BACKGROUND Originally constructed in the early 1990s, Dockweiler Drive currently connects to Sierra Highway to the east and terminates 500 feet west of Valle del Oro to the west. The City of Santa Clarita's (City) General Plan designates Dockweiler Drive as a secondary highway, which has an ultimate design section of four travel lanes, designed to service both through traffic and to collect traffic from collector and local streets. The extension of Dockweiler Drive, as shown on the attached Location Map, is a critical east -west link that would provide a through connection from Sierra Highway to Railroad Avenue, as indicated in the General Plan. This project supports the Building and Creating Community theme of the City's five-year strategic plan, Santa Clarita 2025. On April 10, 2018, the City Council approved the alignment of Dockweiler Drive to connect to Railroad Avenue at 13th Street. This alignment would require improvements to both Arch Street and 13th Street along with a fully upgraded railroad crossing at 13th Street and Railroad Avenue. The proposed roadway improvements would consist of a four -lane roadway with a 12-foot raised landscaped median, a 13-foot-wide sidewalk/parkway, and a 5-foot-wide bike lane on each side. The typical right-of-way width is 92 feet. Additionally, staff was authorized to submit an application to the California Public Utilities Commission, which was approved, for the required improvements at the 13th Street at -grade rail crossing. On July 9, 2019, the City Council approved a design contract with MNS Engineers, Inc. to design the roadway, drainage, and grading from the current terminus of Dockweiler Drive to connect with Railroad Avenue at 13th Street. The scope of work included coordinating with The Master's University and surrounding property owners; working with Southern California Regional Rail Authority (SCRRA) to complete the design of the rail crossing at 13th Street; designing the intersections at Arch Street, 12th Street, and Placerita Canyon Road; and facilitating extensive public outreach meetings for residents, businesses, and agencies. Right-of- way acquisition is required from several property owners to secure the approved alignment. California Environmental Quality Act Requirements The California Environmental Quality Act (CEQA) requirements were completed when the combined Lyons Avenue and Dockweiler Drive Extension Project Final Environmental Impact Report, Environmental Findings, Mitigation Monitoring and Reporting Program, and Statement of Overriding Considerations (collectively, the EIR) were approved and certified through Resolutions 18-10 and 18-11 by the City of Santa Clarita City Council at its regular meeting on April 10, 2018. A Notice of Determination was posted with the State Clearinghouse on April 16, 2018 (SCH 92013082016). In addition to the EIR, the Addendum to the Lyons Avenue and Dockweiler Drive Extension Project Final EIR (City EIR Addendum) was recently completed. The EIR and City EIR Addendum are available in the City Clerk's Reading File. Page 3 Packet Pg. 24 O The City EIR Addendum evaluated the addition of the following (Modified Project), constituting changes from the originally approved project EIR: • A roundabout at 12th Street and Arch Street and signalized "T" intersection at Dockweiler Drive and Placerita Canyon Road; • Railroad Avenue median modifications and dedicated right -turn pedestrian refuge island from 13th Street to Railroad Avenue; • A Class I bicycle and pedestrian pathway and bridge south of Dockweiler Drive, spanning Newhall Creek and connecting to the Jan Heidt (Newhall) Metrolink Station and Newhall Community Center parking lot; • Two basins to capture and treat stormwater; one interim detention basin and conveyance located on the north side of 13th Street and east of the railroad tracks and one infiltration basin located south of the improvements at Placerita Canyon Road; • Union Pacific and Metrolink Railroad reprofiling approximately a quarter -mile of the railroad line and grading improvements; • Property acquisition and/or easements of up to 29 properties (10 more than the 19 identified in the EIR); • Removal of two additional oak trees (four total) and encroachment on eight oak trees; • A larger grading footprint of approximately seven acres (two acres more than the five acres identified in the EIR) on the northern portion of the project site to accommodate roadway and intersection improvements, grading improvements along the railroad line, and the two stormwater basins; and • A longer grading period of up to 18 months (12 months were identified in the EIR). The City EIR Addendum concluded there is substantial evidence to determine that: 1. The City's Modified Project does not represent a substantial change from the approved project evaluated in the EIR; 2. No substantial changes have occurred with respect to the circumstances under which the City's Modified Project is undertaken; and 3. The City's Modified Project has not introduced new information of substantial importance that was not previously known. The City's Modified Project would not have any new or substantially more severe impacts than what was evaluated in the EIR. No new mitigation measures are recommended in addition to those adopted at the time the EIR was certified. The EIR, in conjunction with this City EIR Addendum, provide adequate documentation, pursuant to CEQA for the City's approved and modified project. On November 6, 2024, the Los Angeles County (County) Board of Supervisors found that the County's Placerita Yard Relocation Project Addendum to the Lyons Avenue and Dockweiler Drive Extension Project Final Environmental Impact Report (County EIR Addendum) (SCH 92013082016), complies with the CEQA pursuant to Title 14 of the California Code of Regulation Article 11 sections 15162 and 15164, for changes to the approved project (the County's Modified Project). The County's Modified Project will relocate the County's roadway maintenance yard from 22234 Placerita Canyon Road, to a two -acre un-subdivided portion of an approximately 21.24-acre undeveloped parcel, owned by the City at the easterly terminus of Page 4 Packet Pg. 25 O Norland Drive, between State -Route 14 and the Santa Clara River, through a Real Property Exchange Agreement between the City and the County. The County EIR Addendum is available in the City Clerk's Reading File. California Department of Housing and Community Development Resolution The approved alignment requires right-of-way acquisition from several property owners including the County, Laurene F. Weste (Ms. Weste), and Prostor Land, LLC. Staff has obtained preliminary approval from the California Department of Housing and Community Development (HCD) of an exemption from the Surplus Lands Act to exchange City -owned property to secure the necessary right-of-way for Dockweiler Drive from these three property owners. The attached HCD Resolution will be submitted for formal approval after it is adopted by the City. The County also prepared a resolution declaring its maintenance yard in Placerita Canyon and portions of Lyons Avenue and Placerita Canyon Road to be exempt from the Surplus Lands Act. The County Board of Supervisors adopted the resolution during its regular meeting on November 6, 2024. County Real Property Exchange Agreement The approved alignment for Dockweiler Drive would render the County's existing Placerita Maintenance Yard unusable. The City and County have negotiated a property exchange to provide similar property in another portion of the City, along Norland Drive, for the County maintenance yard to allow for the City's approved alignment of Dockweiler Drive. City and County staff prepared a Real Property Exchange Agreement that will be approved by the attached City/County Exchange Resolution. The County Board of Supervisors approved their agreement of real property transfer with the City during its regular meeting on November 6, 2024. In accordance with this agreement, the County will quitclaim its interest in the maintenance yard along with its interest in the portions of Lyons Avenue, Emberbrook Drive, and Placerita Canyon Road, located east of the Metrolink railroad tracks, as shown on Page 1 of the attached County Land Exchange Exhibit. In exchange, the City will quitclaim interest in a two -acre sub -parcel between State Route 14 and the Santa Clara River, along Norland Drive, which is part of a larger 21.24-acre parcel adjacent to and east of Oak Springs Canyon Drive as shown on Page 2 of the County Land Exchange Exhibit. The agreement requires the City to pay the County $1,100,000 for expenses associated with relocating its maintenance yard. The City will grant a 24-foot-wide easement to the County to provide ingress, egress, and utility access from Oak Springs Canyon Road to the two -acre sub -parcel. In addition, the City will reserve a 24-foot-wide easement for ingress, egress, and utility purposes across the two -acre sub - parcel to allow the City to pass through. The County's maintenance yard in Placerita Canyon is subject to a lease with the South Coast Air Quality Management District (SCAQMD). The lease allows SCAQMD to operate an air monitoring station on a 1,575-square-foot portion of the County maintenance yard. The lease payments are currently paid on a month -to -month basis for $50 per month. The lease will transfer to the City of Santa Clarita upon close of escrow. Page 5 Packet Pg. 26 O A portion of the Lyons Avenue right-of-way, to be acquired from the County, is not needed for the construction of the Dockweiler Drive Extension project. This land will be exchanged with other land owners to obtain the required right-of-way. Resolution of Vacation of Norland Drive. Portions of Lvons Avenue. and Placerita Canvon Road The County requested that the City support the vacation of Norland Drive as part of the Real Property Transfer Agreement. The offer of dedication for a private and future street to be vacated was originally provided through an offer of dedication to the County on Parcel Map No. 18161, recorded on February 15, 1989. The rights transferred to the City upon annexation on August 15, 2013. The 60-foot-wide dedication is located within the 21.24-acre parcel owned by the City. Based on the criteria outlined in the attached Vacation Resolution, City staff has determined that the offer of dedication is not needed for future public road purposes. The portions of Lyons Avenue and Placerita Canyon Road being acquired from the County were acquired by the County in fee for road purposes. The County also acquired easements for slope purposes and drainage purposes associated with Lyons Avenue. A portion of Lyons Avenue being acquired from the County in fee will be transferred to Ms. Weste and Prostor Land, LLC, in exchange for right-of-way needed for Dockweiler Drive and the Class I bike trail to the Newhall Metrolink Station. The Vacation Resolution will vacate the road, slope, and drainage easements, prior to quitclaiming the fee ownership in exchange for needed right-of-way. The specific easements to be vacated were acquired by the County by instrument numbers listed in the table below. Placenta Canyon Road is maintained as a public road west of Aden Avenue. The Vacation Resolution does not vacate any part of Placerita Canyon Road west of Aden Avenue within the original 40-foot-wide right-of-way. Lvons Avenue and Placerita Canvon Road Easements to be Vacated Instrument Number Date Recorded 3592 June 15, 1967 2999 October 14, 1970 3310 October 6, 1970 2658 January 21, 1971 2660 January 21, 1971 3927 April 1, 1971 2714 January 24, 1972 3184 September 4, 1974 3185 September 4, 1974 3186 September 4, 1974 As outlined in the Vacation Resolution, and per Part 3, Section 8331 and Per Part 3, Section 8333, of the California Streets and Highways Code, these easements may be summarily vacated. Therefore, staff is recommending the easements and offer of dedication be summarily vacated by adopting the resolution for the summary vacation of easements and offer of dedication for private and future street purposes, as described in Exhibit "A" and "G" Legal Descriptions and as shown on Exhibit "B" and "H" Exhibit Maps of the attached resolution. The resolution also includes a reservation of easement for the Southern California Gas Company to continue maintaining and operating its existing gas line facilities and for Charter/Spectrum to continue maintaining and Page 6 Packet Pg. 27 O operating its existing communication line facilities. Laurene F. Weste Real Property Exchange Agreement The approved alignment for Dockweiler Drive goes through portions of Ms. Weste's property. As a City Councilmember, Ms. Weste is required by California conflict of interest laws to recuse herself from making, participating in the making, or otherwise using her official position to influence any of the City's decisions on the Dockweiler Drive Extension project, as the project directly affects her real property. In addition, and absent an available exception to the conflict of interest laws, the City would not be permitted to enter into an agreement with Ms. Weste while she is a councilmember. On August 27, 2021, the California Fair Political Practices Commission (FPPC) determined that an exception applies in this situation to permit the City to enter into an agreement with Ms. Weste because the acquisition of a portion of her property is necessary for the project, provided that Ms. Weste's involvement in this matter is limited to communications with the City in her individual capacity and as a landowner. For these reasons, Ms. Weste has recused herself as a councilmember in matters involving the Dockweiler Drive Extension project, including the consideration of the Weste Land Exchange Agreement. Discussions and negotiations between the City and Ms. Weste, in her private capacity and as a landowner, have occurred between her, her attorney, City staff, and the City's special counsel for this project. With her recusal as a councilmember, the City is not prohibited by the state conflict of interest laws from approving and entering in the proposed agreement with Ms. Weste. The HCD Resolution authorizes a portion of the excess right-of-way of Lyons Avenue to be exchanged with Ms. Weste for a road easement, a slope easement, and a temporary construction easement necessary for Dockweiler Drive. The land and easements being exchanged with Ms. Weste are shown on the attached Weste Land Exchange Exhibit. The real property exchange agreement between the City and Ms. Weste will be approved by and is an exhibit to the City/Weste Exchange Resolution, attached. In this agreement, the City will quitclaim the portion of property obtained from the County that is not needed for the Dockweiler Drive Extension project, and is adjacent to the property owned by Ms. Weste, to Ms. Weste in exchange for Ms. Weste granting easements for public use and road purposes, slope purposes, and temporary construction purposes through her property for the purpose of building Dockweiler Drive. The fee ownership being quitclaimed to Ms. Weste and the right-of-way and easements being granted to the City per the real property exchange agreement between the City and Ms. Weste have been appraised. The land being acquired by Ms. Weste has been valued at $703,000. The right-of-way and easements being acquired by the City have been valued at $686,000. The real property exchange agreement contains a provision for Ms. Weste to pay to the City the difference in value in the amount of $17,000. Page 7 Packet Pg. 28 O As part of the property transfer agreement the City will also agree to the following terms: 1. Following close of escrow, the City will: a. Reimburse Ms. Weste for actual expenses related to relocating the existing septic system, in an amount not to exceed $22,000. Ms. Weste is to relocate the septic system if affected by the proposed project within three months after the close of escrow. b. Compensate Ms. Weste for the relocation of existing animal kennels and cargo containers located within the proposed right-of-way, in the amount of $11,000. The animal kennels and cargo containers will be relocated onto the same parcel outside of the proposed right-of-way. The work is to be completed and expenses to be reimbursed within three months after the close of escrow. c. Compensate Ms. Weste for the relocation of existing water lines, valves, and plant material from the nursery site within the proposed right-of-way, in the amount of $32,000. Ms. Weste is to relocate all irrigation lines and plant material prior to the close of escrow. 2. During construction of Dockweiler Drive, the City will: a. Install construction fencing along the northeast alignment of Dockweiler Drive and County maintenance yard to deter trespassers from entering the Weste property. b. Relocate the existing water meter at the northeast corner of the Weste property, if required due to construction activities. c. Abandon an existing water well located within the Dockweiler Drive alignment and deliver the antique well cap and handle to Ms. Weste. d. Ensure that electrical service to Ms. Weste's residence is retained after undergrounding of electric lines. 3. Following construction of Dockweiler Drive, the City will: a. Maintain landscaping and irrigation within the slope easements adjacent to Dockweiler Drive through Ms. Weste's property. b. Install protective fencing as a barrier to protect animals from wandering into the right-of-way. Both parties have reviewed and commented on the agreement and agree on the terms. Final adjustments will be non -substantive. Prostor Land, LLC Real Property Exchange Agreement The HCD Resolution also authorizes a portion of the excess Lyons Avenue right-of-way and a Page 8 Packet Pg. 29 O portion of the excess County maintenance yard to be exchanged with Prostor Land, LLC, for fee ownership of land needed to construct the Class I bike trail from Dockweiler Drive, including the bridge across the un-named tributary to Newhall Creek, to the Newhall Community Center and the Newhall Metrolink Station as shown on the attached Prostor Land Exchange Exhibit. The real property exchange agreement between the City and Prostor Land, LLC is approved by, and is an exhibit to the City/Prostor Exchange Resolution, attached. This agreement also requires Prostor Land, LLC, to grant temporary construction easements to the City for the construction of Dockweiler Drive. Prostor Land, LLC, will also enter into a new lease with SCAQMD, and the City will provide relocation assistance for SCAQMD to relocate its air monitoring station onto another site on property owned by Prostor Land, LLC. Both parties have reviewed and commented on the agreement and agree on the terms. Final adjustments will be non -substantive. Phase I Environmental Site Assessment A Phase I Environmental Site Assessment has been conducted for the County maintenance yard and the property being acquired in fee from Prostor Land, LLC. The investigations show there were no indications of recognized environmental conditions, and no further studies are recommended or will be completed prior to close of escrow. South Coast Air Quality Management District Lease Agreement A South Coast Air Quality Management District (SCAQMD) air quality sampling station is located on the portion of the County maintenance yard that will be quitclaimed to the City and later quitclaimed to Prostor Land, LLC. The City will work with SCAQMD to relocate its air sampling station to a new mutually agreeable location within Prostor Land, LLC's, storage yard that meets United States Environmental Protection Agency and state air quality monitoring regulations. Agreement with the Newhall School District for Conveyance of Right -of -Way Construction of the Dockweiler Drive Extension project will require the City to obtain right-of- way easements and a license for entry from the Newhall School District at its maintenance yard located at the corner of 12th Street and Arch Street as shown on the attached Newhall School District Exhibit. City staff has coordinated with Newhall School District staff and presented the project to the Newhall School District Governing Board on May 8, 2018, August 11, 2020, and April 25, 2023. The Newhall School District Governing Board approved a resolution and the attached Agreement for Conveyance of Right -of -Way and Grant of License for Entry on May 23, 2023, and June 27, 2023, respectively. The agreement allows the Newhall School District to convey the required easements and grant the City permission to enter the property to construct the project improvements, upon formal approval by the City. Page 9 Packet Pg. 30 O Accept Emberbrook Drive and Street Name Change On June 8, 1971, the County Board of Supervisors set aside a 100-foot strip of land for Emberbrook Drive through Resolution 3414, recorded on June 11, 1971. This 100-foot strip is located within the County's maintenance yard as shown on Page 1 of the attached County Land Exchange Agreement Exhibit. On September 4, 1974, three ownership partners offered to dedicate an easement for public road and highway purposes as instrument numbers 3181, 3182, and 3183. These two triangular parcels are located northwest and southeast of Emberbook Drive described above. The County consented to the recordation, but did not accept the offer. The set - aside strip and the offers to dedicate are within the proposed alignment for Dockweiler Drive and are shown on Page 1 of the attached Los Angeles County Land Exchange Exhibit. To support the right-of-way acquisition for the Dockweiler Drive Extension project, staff recommends the City Council accept these portions of Emberbrook Drive. The attached Resolution to Accept Emberbrook Drive also includes provisions to rename this road to Dockweiler Drive. The City is the entity responsible for authorizing City street name changes and can do so by the adoption of a resolution. City staff has coordinated with the Los Angeles County Fire and Sheriff's Departments, and neither has issues regarding the proposed street name change. There are no parcels with an Emberbrook Drive address. This resolution to accept Emberbrook Drive and rename to Dockweiler Drive will be recorded following the filing of the Notice of Completion of construction. Grant of Easement for Public Use and Road Purposes The Dockweiler Drive Extension project will be constructed across City -owned parcels. Staff recommends that the City grant an easement for public use and road purposes along Dockweiler Drive to allow public utility agencies to construct their facilities within the right-of-way. In addition, an easement for public use and trail purposes will be granted across City -owned parcels to construct the Class I bike trail from Dockweiler Drive to the Newhall Community Center as shown on the Location Map. Budget Appropriation The requested budget appropriation will provide for property acquisition, SCAQMD relocation, Ms. Weste's reimbursable costs, escrow fees, appraisal reports, relocation assistance, staff time, and miscellaneous fees associated with the acquisition and relocation for the project. FISCAL IMPACT Upon approval of the recommended actions, $1,600,000 will be available for right-of-way acquistion in project expenditure account S3023453-516101 (Via Princessa B&T Fee) to support the recommended expenditures and associated project costs.

(CEQA). Staff has determined that an Addendum to the City's previously certified EIR (State Clearinghouse No. 2013082016) for the Dockweiler Extension Project is appropriate for this transaction; and 13001-0007\2934450v20.doc Page 3 of 6 Packet Pg. 36 2.b WHEREAS, by prior action at the same meeting at which this Resolution is considered, the City Council has approved the City's Addendum to the City's previously certified EIR for the Dockweiler Extension Project and also considered a separate County prepared Addendum to the same EIR which evaluated the impacts of the Agreement of Real Property Transfer between the City and the County. The findings contained in the Staff Report for this agenda item, with respect to the approval of both Addendums and the information, content, and analysis contained in those two Addendums, are incorporated herein by this reference as the evidence to support the City Council's determinations that the actions taken by this Resolution are within the scope of the EIR for the Dockweiler Extension Project, and that pursuant to State CEQA Guidelines Section 15164, only minor changes to the EIR were required and that none of the conditions described in State CEQA Guidelines Section 15162 have occurred; and WHEREAS, the accompanying Agenda Report provides supporting information upon which the declarations and findings set forth in this resolution are based. NOW, THEREFORE, the City Council of the City of Santa Clarita, California does hereby resolve as follows: SECTION 1. The above recitals are true and correct and are a substantive part of this Resolution. SECTION 2. The City Council hereby declares: (i) pursuant to Section 54221(b) of the Act, the City Property, the Weste Exchange Property, and the Becker Exchange Property are not necessary for the City's use; and (ii) pursuant to Section 54222(f)(1)(C) of the Act, the City Property is exempt surplus land because the City intends to exchange the City Property for the County Property for the City's use to complete the Dockweiler Extension Project; the Weste Exchange Property is exempt surplus land because the City intends to exchange the Weste Exchange Property for the Weste Property for the City's use to complete the Dockweiler Extension Project; and the Becker Exchange Property is exempt surplus land because the City intends to exchange the Becker Exchange Property for the Becker Property for the City's use to complete the Bike Path Project. SECTION 3. This resolution has been reviewed with respect to the applicability of the California Environmental Quality Act (Public Resources Code Section 21000 et seq.) (CEQA). The City Council concurs in staff s determination that the City's Addendum to the City's previously certified EIR (State Clearinghouse No. 2013082016) for the Dockweiler Extension Project and the County's Addendum to the same EIR appropriately describes and evaluates the potential environmental impacts for the land exchanges described in this Resolution. The City further finds that each of the three land exchanges (between the City and the County, between the City and Laurene F. Weste and between the City and Prostor Land, LLC) contemplate actions that are within the scope of the projects evaluated in the above -described environmental documents, that all potentially significant environmental impacts from the project have been mitigated to level of less than significance and that such mitigation measures are part of and incorporated into the previously adopted Mitigation Monitoring and Reporting Plan that was adopted in connection with each above -described environmental document, and that any impacts that are not mitigated to a level of less than significance are addressed in the Findings and Statement of Overriding Considerations that accompanied the Final EIR for the Dockweiler Drive Extension Project, which findings are incorporated herein as set forth in full and adopted 13001-0007\2934450v20.doc Page 4 of 6 Packet Pg. 37 2.b by this provision. The City Council makes these findings and determinations as an exercise of its independent judgment. SECTION 4. Staff of the City are hereby authorized and directed to provide a copy of this resolution to HCD in the form and manner required by HCD at least 30 days prior to the disposition of the City Property, the Weste Exchange Property and the Becker Exchange Property. SECTION 5. The officers and staff of the City are hereby authorized, jointly and severally, to do all things which they may deem necessary or proper to effectuate the purposes of this resolution, and any such actions previously taken are hereby ratified and confirmed. SECTION 6. This resolution will become effective immediately upon adoption. PASSED, APPROVED, and ADOPTED this day of , 2024.

The proposed Dockweiler Extension Project is a multi -phased capital improvement project being coordinated by the City and The Master's University to improve circulation and access to the Placerta Canyon and Newhall communities in the City. The proposed Dockweiler Extension Project would extend Dockweiler Drive from the existing terminus to Railroad Avenue at 13's Street; and WHEREAS, a portion of the land area to be acquired for the Dockweiler Drive Extension Project is within the land area that has either been already acquired by the County of Los Angeles ("County") for Emberbrook Drive or within land areas subject to offers of dedication for Emberbrook Drive that have not previously been accepted by the County; and WHEREAS, in connection with the Dockweiler Extension Project, the City has concurrently with the adoption of this Resolution, approved an "Agreement of Real Property Transfer" with the County by which the City is acquiring the County's interest in certain properties, including: (i) the property which the County currently uses as a roadway maintenance yard and which is generally located at 22234 Placerta Canyon Road, including a strip of land between the maintenance yard and the southerly side of Placenta Canyon Road; (ii) Emberbrook Drive from its intersection with Placenta Canyon Road through the County's maintenance yard until its southeasterly terminus (the "County Property'); and WHEREAS, the County's interests in Emberbrook Drive that the City is acquiring from the County include, but are not limited to: (i) ownership in fee of certain portions of Emberbrook Drive acquired by deeds and recorded as Document Numbers t 10 and 342 both of which were recorded on May 25, 1960, in Book D856 on pages 887 and 977, which portions were set aside for public road purposes in accordance with Section 941 of the Streets and Highways Code pursuant to Resolution 3414, adopted by the County Board of Supervisors on June 8, 1971, and recorded on June 11, 1971; and (ii) certain offers to dedicate other planned portions of Emberbrook Drive that were shown on Parcel Map 3602 recorded on September 4, 1974, and which offers were separately recorded as Document Nos. 3181, 3182 and 3183 on September 4, 1974; and WHEREAS, Government Code section 66477.2 provides that if an offer of dedication is rejected at the time a final map is approved that offer remains open, then the offer of dedication may be accepted at a later date, and without further action by the subdivider, by resolution of the legislative body; and WHEREAS, upon the City's acquisition of the County's interests in Emberbrook Drive, the City intends to accept the outstanding offers of dedication for road purposes for Emberbrook Drive, change the name of Emberbrook Drive to Dockweiler Drive, construct the Dockweiler 13001-0OOT3024976A da Drive Extension Project, and then accept the extension of Dockweiler Dive into the City's road system; and WHEREAS, on April 10, 2018, the City Council certified the Final Environmental Impact Report ("EIR") for the Dockweiler Extension Project by way of City Council Resolution No. 18-10, and approved the Extension Project by way of City Council Resolution 18-11; and WHEREAS, City staff has reviewed this Resolution with respect to the applicability of the California Environmental Quality Act (Public Resources Code Section 21000 et seq.) ("CEQA"). City staff has determined that an Addendum to the City's previously certified EIR (State Clearinghouse No. 2013082016) for the Dockweiler Extension Project is appropriate to accept the outstanding offers of dedication for road purposes that were provided by Emberbrook Drive and for the renaming of those segments to be part of Dockweiler Drive; and WHEREAS, by prior action at the same meeting at which this Resolution is considered, the City Council has approved the City's Addendum to the City's previously certified EIR for the Dockweiler Extension Project and also considered a separate County prepared Addendum to the same EIR which evaluated the impacts of the Agreement of Real Property Transfer between the City and the County. The findings contained in the agenda report for this agenda item, with respect to the approval of both Addendums and the information, content, and analysis contained in those two Addendums, are incorporated herein by this reference as the evidence to support the City Council's determinations that the actions taken by this Resolution are within the scope of the FIR for the Dockweiler Extension Project, and that pursuant to State CEQA Guidelines Section 15164, only minor changes to the EIR were required and that none of the conditions described in State CEQA Guidelines Section 15162 have occurred; and WHEREAS, the City Council also finds that there is a need to change the street name of Emberbrook Drive to Dockweiler Drive because the land area to be included within Dockweiler Drive includes the land within Emberbrook Drive and there is a need to provide continuity in the time of the roadway through the entirety of the length under the Dockweiler Extension Project; and WHEREAS, no properties, residents or businesses currently have an assigned address of Emberbrook Drive and thus no property owner, resident of business will be impacted by the change in the street time; and WHEREAS, the Los Angeles County Fire Department and Los Angeles County Sheriff s Department have no objection with such a street name change; and WHEREAS, Government Code Section 34091.1 permits the City Council of a City, by resolution, to change the time of streets within its jurisdiction when the City Council find that such existing street time should be changed.

The District and the City may be referred to herein individually as a "Party' and collectively as the "Parties." RECITALS A. The City has undertaken efforts to plan, design, approve, and construct an extension of Dockweiler Drive, which would result in an east -west arterial through the City, from Sierra Highway to Railroad Avenue ("Dockweiler Extension Project"). A primary purpose of the Dockweiler Extension Project is to improve access and circulation for the Placerita Canyon and Newhall communities. B. The District owns real property located within the City's boundaries, at the northwesterly corner of the intersection of Placerita Canyon Drive and 121h Street ("Property"). The Property is identified as Los Angeles County Assessor Parcel Number 2833-001-900, and the Property is depicted in Exhibit "A" attached to this Agreement. The District uses the Property for operations, maintenance and warehouse purposes, and at no time does the District require or permit any of its students to be present at or on the Property. C. As part of the Dockweiler Extension Project, the City has proposed to construct certain improvements to the intersection of Placerita Canyon Drive and 121h Street (the "Intersection") that would require work both within the current public right of way at the Intersection and along portions of Placerita Canyon Drive and 121h Street, and on portions of the Property ("City Work"). The City Work includes, generally: (i) realignment of Placerita Canyon Road and construction of a traffic circle at the Intersection; and (ii) realignment and replacement of curbs, gutters, driveways, and other facilities on the Property. A detailed description of the City Work is set forth in Exhibit "B" attached to this Agreement. D. To facilitate construction of the City Work, the City has requested that the District: (i) convey to the City a right of way over portions of the Property, to accommodate portions of the traffic circle and related street improvements ("Right of Way'); and (ii) grant to the City a temporary license for entry over portions of the Property, to accommodate construction activities ("License for Entry"). Exhibit "C" attached to this Agreement sets forth depictions of: (i) the portions of the Property within the proposed Right of Way; and (ii) the portions of the Property that would be subject to the License for Entry ("Entry Area"). E. Education Code ("EC") Section 17556 etseq. sets forth the authorization and process for a public school district to convey property interests to municipal corporations, for public street or highway purposes. During its regular, open session meeting on June 13, 2023, and in accordance with EC Section 17557, the Governing Board of the Newhall School District ("District Board") took the first step in the process by approving and adopting Resolution No 22.23-27 by not less than a two-thirds affirmative vote of all District Board members, to thereby state, among other things, the District Board's intent: (i) to grant the Right of Way to the City; and (ii) to conduct a public hearing and consider granting the Right of Way to the City, during the District Board's at 6:00 p.m., or as soon thereafter as practicable, on June 27, 2023, in the District Board's meeting room. BWS/06-16-23 -1- Right of Way and License for Entry: Placerita Canyon Road and 12" Street 005379.0008140 354858.2 F. In accordance with EC Section 17558, the District: (i) caused copies of Resolution No. 22.23-27 signed by all or at least a majority of the members of the District Board, to be posted on , at three public places within the District's boundaries; and (ii) caused notice of adoption of Resolution No. 22.23-27 and of the time, date, and place of the meeting at which the District Board would consider conveyance of the Right of Way to the City, to be published in the Santa Clarita Valley Signal, a newspaper of general circulation. G. On June 27, 2023, the District Board duly opened, conducted, and closed the public hearing regarding the proposed conveyance of the Right of Way to the City. During the meeting held on June 27, 2023, no protest against the proposed conveyance of the Right of Way, signed by at least 10 percent of the District's qualified electors, was filed with the District Board. Following close of the public hearing, the District Board approved and adopted Resolution No. 22.23-27 to thereby: (i) approve this Agreement and authorize District staff to cause this Agreement to be fully executed and delivered by both Parties; and (ii) subject to the foregoing, authorize the conveyance of the Right of Way to the City and direct District staff to execute the deed of conveyance and deliver it to the City. H. The purpose of this Agreement is to set forth the terms and conditions for the District to convey the Right of Way to the City, as authorized by EC Section 17556, and to grant the associated License for Entry to the City. Now, in consideration of the foregoing and of the Parties' respective rights and obligations pursuant to this Agreement, consideration that each Party acknowledges is adequate, the Parties hereby agree as follows: AGREEMENT PARTI. CONVEYANCE OF RIGHT OF WAY AND GRANT OF LICENSE FOR ENTRY Section 1.1 Conveyance of Right of Way. Within fifteen calendar days following either the Effective Date or the date both Parties have duly authorized, signed, and delivered this Agreement, whichever is later, the District shall sign and deliver to the City a "Conveyance of Right of Way" substantially in the form set forth in Exhibit "D" attached to this Agreement, notarized to permit recording by the City. Section 1.2 Grant and Scope of License for Entry. Subject to all other provisions of this Agreement, the District hereby grants the License for Entry to the City. The License for Entry is for all purposes a temporary and non-exclusive contractual license for City officers, employees, consultants, contractors and subcontractors (each a "City Representative") to enter in and upon the Entry Area, at any and all reasonable times during the License Term (defined in Section 1.3 herein), for purposes related to performance of the City Work.

Subsection 1.4.2 Preconstruction. On and after the Effective Date, and as authorized by the License for Entry, the City Representatives may enter in and upon the Entry Area for purposes relating to the planning, design, and other pre -construction activities associated with the City Work ("Pre -Construction Activities"). Prior to entry onto the Entry Area in connection with the Pre - Construction Activities, the City shall, in each case, provide written notice of entry to the District (each an "Entry Notice") not less than 24 hours prior to the entry. However, in each case that the City Representatives intend to conduct any soil sampling, boring, or other invasive or destructive testing, the City must: (i) provide the Entry Notice to the District not less than seven calendar days prior to the date the invasive or destructive testing will be performed; and (ii) obtain the District's written consent to the testing, which consent the District shall not unreasonably deny, delay, or condition. Subsection 1.4.3 Construction. Prior to first entering in or upon the Right of Way and/or the Entry Area for purposes of commencing construction activities associated with the City Work (which include, without limitation, staking, grubbing, excavation, grading, installation, etcetera), the City must provide written notice to the District of the City's intent to commence construction of the City Work ("Commencement Notice").

INTRODUCTION (a) Purpose of the EIR The purpose of this Final Environmental Impact Report (Final EIR) is to inform decision makers and the general public of the potential environmental impacts resulting from the proposed Lyons Avenue/Dockweiler Drive Extension Project ("Proposed Project"). The Proposed Project will require approval of certain discretionary actions by the City of Santa Clarita, and therefore, is subject to environmental review requirements under the California Environmental Quality Act (CEQA). For purposes of complying with CEQA, the City of Santa Clarita, located at 23920 Valencia Boulevard, CA 91355 is identified as the Lead Agency for the Proposed Project. As described in Section 15121(a) and 15362 of the CEQA Guidelines, an environmental impact report is an informational document which will inform public agency decision -makers and the public of the significant environmental effects of a project, identify possible ways to mitigate any significant environmental effects, and identify and evaluate a reasonable range of alternatives to the project that have the potential to mitigate or avoid the project's potential significant environmental effects while feasibly accomplishing most of the project's basic purposes. Therefore, the intent of this Final EIR is to focus the discussion on the Proposed Project's potential physical effects on the environment, which may be significant under the methodology and thresholds of significance identified within each Section of this Final EIR. Where applicable, the Final EIR recommends feasible mitigation measures that could potentially reduce or avoid significant environmental impacts. This Final EIR was prepared in accordance with Section 15151 of the CEQA Guidelines, which defines the standards for adequacy of an environmental impact report as follows: An EIR should be prepared with a sufficient degree of analysis to provide decision makers with information which enables them to make a decision which intelligently takes account of environmental consequences. An evaluation of the environmental effects of a Project need not be exhaustive, but the sufficiency of an EIR is to be reviewed in the light of what is reasonably feasible. Disagreement among experts does not make an EIR inadequate, but the EIR should summarize the main points of disagreement among the experts. The courts have looked not for perfection but for adequacy, completeness, and a good faith effort at full disclosure. Lyons Avenue/Dockweiler Drive Extension Project Final EIR 1. Executive Summary State Clearing House No. 2013082016 Page 1-1 City of Santa Clarita February 2018 (b) Overview of the Proposed Project Project Location The Project Site is located in the City of Santa Clarita, California located about 35 miles north of Downtown Los Angeles. The Project Site is located at the intersection of Lyons Avenue and Railroad Avenue and extends eastward towards the General Plan alignment for Dockweiler Drive towards The Master's University and northwest towards the intersection of 12th Street and Arch Street. The Project Site also includes the closure of an at -grade crossing at the intersection of Railroad Avenue and 13th Street. The limits for the Lyons Avenue/Dockweiler Drive extension ("Project Site") are from Railroad Avenue on the west to the future Master's University Master Plan Dockweiler extension to the east. Overview of the Environmental Setting The Project Site is currently zoned for MXN (Mixed Use Neighborhood). The portion of the Project Site that crosses the UP/Metrolink Railroad line is zoned for PI (Public Institutional). The General Plan land use designation of the Project Site is Mixed Use Neighborhood (MXN). The General Plan states that areas with a MXN designation should be developed to create neighborhoods that combine residential uses with complementary commercial services, including retail and office uses. MXN zoned areas should be located in close proximity to public transit and provide roadway and trail linkages to adjacent development. The PI zoning designation identifies lands that are used for various types of public and/or community serving facilities owned and operated by public agencies, special districts, non-profit organizations and other entities. Allowable uses include civic and governmental offices, public works yards, public or private schools, libraries, day care centers, airports, hospitals and supporting medical facilities, museums, fire stations, police stations, landfills, and prisons. The Project Site is also located in the Placerita Canyon Special Standards District (PCSSD) and is part of the North Newhall Area (NNA), which includes a Mixed Use Overlay Zone. Overview of the Proposed Project The proposed Lyons Avenue/Dockweiler Drive Extension Project is a multi -phased capital improvement project being coordinated by the City of Santa Clarita and The Master's University to improve circulation and access to the Placerita Canyon and Newhall Communities. The proposed connection and extension of Lyons Avenue to Dockweiler Drive is identified in the Circulation Element of the City's General Plan as one of the primary east -west arterials through the City of Santa Clarita that would provide a through connection from Sierra Highway to Railroad Avenue. The Proposed Project would extend Lyons Avenue from its existing terminus at Railroad Avenue, eastward to Dockweiler Drive to provide a T-intersection, and would extend northwest to connect with the intersection of Arch Street and 12th Street and southeast towards the General Plan alignment for Dockweiler Drive at The Master's University. The Proposed Project also includes the closure of an at - grade railroad crossing at the intersection of 13th Street and Railroad Avenue and the addition of a new at - Lyons Avenue/Dockweiler Drive Extension Project Final EIR 1. Executive Summary State Clearing House No. 2013082016 Page 1-2 City of Santa Clarita February 2018 grade railroad crossing at the intersection of Railroad Avenue and the proposed Lyons Avenue intersection. The Lyons Avenue/Dockweiler Drive extension would extend to the approved alignment of Dockweiler Drive at The Master's University campus. In coordination with the proposed Railroad Bike Path project, the new Dockweiler Drive extension will result in creating a vital Complete Street link between the communities to the east of the railroad/ Newhall Creek (including The Master's University) and Old Town Newhall and Metrolink station. A detailed description of the Proposed Project including specific street improvements is presented in Section 2 Project Description of the Draft EIR. B. ENVIRONMENTAL REVIEW PROCESS (a) Notice of Preparation/Scoping Meeting In compliance with Section 15082 of the CEQA Guidelines, a Notice of Preparation (NOP) was prepared by the City of Santa Clarita and distributed to the State Clearinghouse, Office of Planning and Research, responsible agencies, and other interested parties on August 5, 2013.

Lyons Avenue/Dockweiler Drive Extension Project Final EIR 1. Executive Summary State Clearing House No. 2013082016 Page 1-5 City of Santa Clarita Table 1-1 Summary of Environmental Impacts and Mitigation Measures February 2018 Environmental Impacts Mitigation Measures Level of Significance After Mitigation Aesthetics Temporary Construction Impacts MM 4.1-1: Construction equipment, debris, and Less Than Significant stockpiled equipment shall be visually Impact. The Proposed Project's construction activities would involve grading, screened to effectively block the line -of -sight debris and soils stockpiles, building materials and construction from the ground level of neighboring equipment, all of which could occupy the field of view of passing residential properties. Such barricades or motorists and pedestrians along Lyons Avenue, Railroad Avenue, enclosures shall be maintained in appearance Market Street, Race Street, and the Arch Street/12'h Street/Placerita throughout the construction period. Graffiti Canyon intersection, and nearby residential properties on Aden shall be removed immediately upon Avenue. The existing visual character of the Project Site would discovery. temporarily change from construction -related activities during the duration of the construction period. This impact would be considered significant but temporary. Long Term Operational Impacts MM 4.1-2: The roadway median and contoured slopes Less Than Significant along the roadway alignment shall be Impact. Upon completion of the Proposed Project, the aesthetic character of the attractively landscaped and maintained in Project Site and its immediate surroundings would be permanently accordance with landscape plans to the altered. Views of the intersection at Lyons Avenue and Railroad satisfaction of the City Planning Department. Avenue will be altered to allow for the construction of a new SCRRA/UP railroad at -grade crossing east of Railroad Avenue and the addition of a new bridge crossing at Newhall Creek. Views of the intersection of Lyons Avenue and Railroad Avenue and the hillside on the southeast portion of the Project Site will be altered by grading for the proposed roadway alignment. Views of the Project Site at the intersection of Railroad Avenue and I P Street will also be altered as a result of the closure of the at -grade railroad crossing. The extension of the proposed roadway is consistent with the City of Santa Clarita's General Plan and with the approved Master's University Master Plan. The roadway extension would be developed in accordance with the City's roadway standards and design guidelines. Lyons Avenue/Dockweiler Drive Extension Project Final EIR 1. Executive Summary SCH No. 2013082016 Page 1-6 City of Santa Clarita February 2018 Environmental Impacts Mitigation Measures Level of Significance After Mitigation Loss of Oak Trees See mitigation measure 4.3-7, below. Less Than Significant Impact. Two oak trees occur within the project limits and would be removed for project construction. The removal of or encroachment to oak trees as a result of project construction would be considered a significant impact under both the City of Santa Clarita and CEQA. Replacement oak trees would be planted in the number necessary to comply with the requirements stipulated in the Oak Tree Permit issued by the City. With approval of the required oak tree permits, and implementation of Mitigation Measure 4.3-7 in Section 4.3, Biological Resources, aesthetic impacts associated with the loss or pruning of any oak tree would be reduced to less than significant levels. Alteration of A Significant Ridgeline No mitigation measures are required. Less Than Significant Impact. Construction of the proposed roadway alignment will permanently alter a significant ridgeline as designated in the City of Santa Clarita General Plan. The eastern segment of the Dockweiler alignment was previously approved under a separate project entitlement for The Master's University in 2009, which included a Ridgeline Alteration Permit for the eastern segment of this ridgeline. As part of the approved entitlements for The Master's College Plan in 2008, the extension of Dockweiler Drive east of the Project Site was found to result in the permanent and irreversible grading and re -contouring of the ridgeline. The grading limits of the proposed Project would retain the gradual elevation profile of the base of the ridgeline. Views of the altered portion of the ridgeline would be visible from limited points along the public rights -of -way along Market Street and Race Street to the south of the Project Site. As a project design feature the grading plan incorporates landform grading practices to blend the manufactured slopes and required drainage benches into the natural topography to the maximum extent feasible. Plant materials will be utilized to protect slopes from slippage and soil erosion and minimize the visual effects of grading and construction on a hillside area. With incorporation of the Dockweiler Drive Alignment Project Final EIR 1. Executive Summary State Clearinghouse No. 2013082016 Page 1-7 City of Santa Clarita February 2018 Environmental Impacts Mitigation Measures Level of Significance After Mitigation project design features to develop and improve a new roadway extension that is consistent with the City's roadway design standards, the Proposed Project would result in a less than significant impact with respect to the loss of an aesthetic natural feature. Visual Character No mitigation measures are required. Less Than Significant Impact. No buildings or development is proposed on the Project Site that would block existing views or substantially degrade the visual character of the existing site. Upon completion, Dockweiler Drive will be improved as a pedestrian and bicycle friendly roadway Project features such as bike routes and pedestrian walkways would increase accessibility to scenic natural resources including Newhall Creek and surrounding ridgelines and mountains. Therefore, the Project would have a less than significant impact with respect to public scenic vistas. Roadway Light and Glare No mitigation measures are required. Less Than Significant Impact. The Project would introduce nighttime lighting to the Project Area, which will include pole -mounted street lights at intersections for public safety purposes, lighted bollards along Dockweiler Drive, flashing safety lighting for the proposed at -grade crossing, and would contribute to additional light and glare from headlights of vehicles utilizing the roadway. Lighting associated with the Proposed Project is not anticipated to substantially impact any surrounding sensitive uses. Overall, the Project would be expected to slightly increase ambient lighting in the area, but compliance with the design standards and requirements established in the Santa Clarita Municipal Code Section 17.50.05 would mitigate lighting impacts to a less than significant level. Dockweiler Drive Alignment Project Final EIR 1. Executive Summary State Clearinghouse No. 2013082016 Page 1-8 City of Santa Clarita February 2018 Environmental Impacts Mitigation Measures Level of Significance After Mitigation Air Quality Construction No mitigation measures are required. Less Than Significant Impact. Construction of the Proposed Project would occur over an approximately 12-month timeframe and would involve clearing, grading, excavation, trenching, and asphalt paving. Construction would require 4,990 cubic yards (cy) of cut, 2,760 cy of fill, and 2,230 cy of soil export associated with grading and excavation. Sources of emissions during construction include: stationary and mobile uses of construction equipment, construction vehicles (heavy-duty construction vehicles and worker vehicles), and energy use. Additionally, earthwork and construction activities would generate fugitive dust emissions. These construction -related emissions and their associated air quality impacts would be short-term in nature and limited only to the period when construction activity is actively taking place. The Proposed Project's construction emissions would be below SCAQMD's significance thresholds for all criteria pollutants. Therefore, the Proposed Project's regional construction air quality emissions would be less than significant. No mitigation measures are required. Less Than Significant AQMP Consistency Impact. The Proposed Project would not exceed the AQMD's significance thresholds for regional construction emissions and thus would not increase the frequency or severity of existing air quality violations or cause or contribute to new air quality violations within the Basin. The Project is consistent with the AQMP and would not interfere with attainment of air quality levels identified in the AQMP. The Project would help reduce congestion and vehicles per miles travelled by providing sidewalks and bicycle lanes and by providing direct access from the residential area and The Master's University area to the Jan Heidt Newhall Metrolink Station and Old Town Newhall. The Project encourages alternative modes of transportation other than motor Dockweiler Drive Alignment Project Final EIR 1. Executive Summary State Clearinghouse No. 2013082016 Page 1-9 City of Santa Clarita February 2018 Environmental Impacts Mitigation Measures Level of Significance After Mitigation vehicles and would be consistent with the goals and objectives of the AQMP to reduce vehicle emissions throughout the Basin.

Application of non -toxic binders to exposed areas after cut and fill operations and hydroseeded areas. g. Plant vegetative ground cover in disturbed areas as soon as possible and where feasible. h. Operate street sweepers that comply with SCAQMD Rules 1186 and 1186.1 on roads adjacent to the construction site so as to minimize dust emissions. Paved parking and staging areas shall be swept daily. i. Scheduling truck deliveries to avoid peak hour traffic conditions, consolidating truck deliveries, and prohibiting truck idling in excess of 5 minutes. j. Reduce traffic speeds on all unpaved roads to 15 miles per hour or less. k. Pave or apply gravel on roads used to access the construction sites when possible. 1. Minimize idling time either by shutting equipment when not in use or reducing the time of idling to 5 minutes as a maximum. M. Limit, to the extent feasible, the hours of operation of heavy-duty equipment and/or the amount of equipment in use. MM 4.2-2 All off -road diesel -powered construction equipment greater than 50 hp shall meet the Tier 4 emission standards, where available. Dockweiler Drive Alignment Project Final EIR 1. Executive Summary State Clearinghouse No. 2013082016 Page 1-11 City of Santa Clarita February 2018 Environmental Impacts Mitigation Measures Level of Significance After Mitigation In addition, all construction equipment shall be outfitted with BACT devices certified by GARB. Any emissions control device used by the contractor shall achieve emissions reductions that are no less than what could be achieved by a Level 3 diesel emissions control strategy for a similarly sized engine as defined by CARB regulations. A copy of each unit's certified tier specification, BACT documentations, and GARB, SCAQMD, or ICAPCD operating permit shall be provided at the time of mobilization of each applicable unit of equipment. MM 4.2-3 An information sign shall be posted at the entrance to each construction site that identifies the permitted construction hours and provides a telephone number to call and receive information about the construction project or to report complaints regarding excessive fugitive dust generation. Any reasonable complaints shall be rectified within 24 hours of their receipt. MM 4.2-4 The contractor shall utilize low-VOC content coatings and solvents that are consistent with applicable SCAQMD and ICAPCD rules and regulations. No mitigation measures are required. Less Than Significant Operational Emissions Impact. Although the Proposed Project would not directly generate any new vehicle trips, the Proposed Project would result in changes to the traffic circulation in the vicinity and would alter the average daily traffic Dockweiler Drive Alignment Project Final EIR 1. Executive Summary State Clearinghouse No. 2013082016 Page 1-12 City of Santa Clarita February 2018 Environmental Impacts Mitigation Measures Level of Significance After Mitigation volumes and peak hour traffic volumes at local intersections. A CO hotspot analysis was conducted, and it was found that, under worst - case conditions, future CO concentrations at each intersection would not exceed the state 1-hour and 8-hour standards with or without the development of the Project. Therefore, no significant project -related impact would occur relative to future carbon monoxide concentrations. The Proposed Project would have a less than significant impact with respect to this criterion. Biological Resources Habitat Modification MM 4.3-1 The applicant shall retain a qualified Less Than Significant biologist with a CDFG Scientific Collection Impact. Permit and Memorandum of Understanding (1) Vegetation to conduct preconstruction surveys for the silvery legless lizard within the Project Site Site grading plans indicate that within the Project Site 2.32 acres of and area.

The only special -status plants observed during the field investigation were two coast live oaks. No other special -status plants are considered to have a high potential for occurrence within the Project Site. A permit is required for the encroachment into the Protected Zone. Native oak trees are protected under City of Santa Clarita Oak Tree Ordinance (Ordinance No. 89-10, passed by the City Council on April 25, 1989) and the City's Oak Tree Preservation and Protection Guidelines Dockweiler Drive Alignment Project Final EIR 1. Executive Summary State Clearinghouse No. 2013082016 Page 1-13 City of Santa Clarita February 2018 Environmental Impacts Mitigation Measures Level of Significance After Mitigation (adopted September 11, 1990). The removal of or encroachment to oak trees as a result of project construction would be considered a significant impact under both the City of Santa Clarita and CEQA. Replacement oak trees would be planted in the number necessary to comply with the requirements stipulated in the Oak Tree Permit issued by the City. With approval of the required oak tree permits, and implementation of Mitigation Measure 4.3-7, impacts upon the loss or pruning of any oak tree would be reduced to less than significant levels. (2) Wildlife MM 4.3-2 Active nests of native bird species are Less Than Significant protected by the Migratory Bird Treaty Act Impact.

Implementation of mitigation measures 4.3-1 and 4.3-2 days have elapsed between the survey and would reduce impacts to the silvery legless lizard and nesting birds to a ground -disturbing activities. less than significant level. Surveys shall include examination of natural habitat for nesting birds. Several bird species such as killdeer and night hawks are known to nest on bare ground. Protected bird nests that are found within the construction zone shall be protected by a buffer deemed suitable by a qualified biologist, and verified by CDFW. Typically, a 300-foot buffer is required for most species and a 500-foot buffer for raptor species. Buffer areas shall be delineated with orange construction fencing or other exclusionary material that would inhibit access within the buffer zone. Installation of the exclusionary material delineating the buffer zone shall be verified by a qualified biologist prior to initiation of construction activities. The buffer zone shall remain intact and maintained while the nest is active (i.e., occupied or being constructed by the adults bird(s)) and until young birds have fledged and no continued use of the nest is observed, as determined by a qualified biologist. (3) Federally Protected Wetlands MM 4.3-3 Prior to project construction, the following is Less Than Significant required to mitigate impacts to jurisdictional Impact. Based on field investigations, two CDFW jurisdictional features occur resources: within the Project Site, the Newhall Creek and a small ephemeral a.

With the Clean Water Act and a 401 implementation of MM 4.3-3, impacts to jurisdictional resources would Certification from the State Water be reduced to a less than significant level. Resources Control Board, and any modification to a streambed, [analysis states none is present], will require a streambed alteration agreement from CDFW pursuant to Section 1600 of the California Fish and Game Code). Both the streambed alteration agreement and the 401 and 404 permits will required specific mitigations for any impacts within their respective jurisdictions. b. Because the proposed bridge is a `span' design, it does not require footings within the bed of the stream. However, plan designs do include approximately 450 feet of bank stabilization on both sides of the stream that would lie within CDFW, ACOE and Regional Water Quality Control Board jurisdiction. Since little vegetation exists within this drainage, it is uncertain what mitigation these regulatory agencies may require. C. The stream in the impacted area would not be conductive to re -vegetation as the area of the project is deeply incised with little existing vegetation and newly planted vegetation would likely be washed away with the next storm event. d. Mitigation can be completed off site. Because there is essentially no riparian Dockweiler Drive Alignment Project Final EIR 1. Executive Summary State Clearinghouse No. 2013082016 Page 1-16 City of Santa Clarita February 2018 Environmental Impacts Mitigation Measures Level of Significance After Mitigation vegetation being removed with implementation of this project, revegetation off site, in a location approved by the City and CDFW, would be accomplished at a 1:1 area ratio. e. Upon City and agency approval of a suitable location, a detailed restoration plan shall be prepared that provides a planting palette, planting methods, and irrigation plan (as appropriate). The plan will also include a 5-year monitoring effort to ensure success of the restoration effort. The monitoring plan will include monitoring methods, monitoring frequency, success criteria, and contingency actions should the success criteria not be met for any reason. Annual monitoring reports shall be provided to both CDFW and the City. (4) Wildlife Movement and Corridors No mitigation measures are required. Less Than Significant Impact. The Project Site is generally surrounded on three sides by development and road networks. However, Newhall Creek does extend through the Site and provides passage through developed areas between the Santa Clarita River and the Angeles National Forest to the southeast and is considered a part of a wildlife movement or migration corridor. To limit impacts to wildlife movement, four 25-foot wide and 8-foot deep openings in a concrete box bridge with 80-foot wide soft base and 2:1 protected side slopes is proposed where the proposed roadway extension crosses Newhall Creek. As designed, this bridge would not result in any barrier to wildlife movement and would serve to protect Newhall Creek as a functioning wildlife movement corridor. The Dockweiler Drive Alignment Project Final EIR 1. Executive Summary State Clearinghouse No. 2013082016 Page 1-17 City of Santa Clarita February 2018 Environmental Impacts Mitigation Measures Level of Significance After Mitigation project as proposed would not result in significant impacts to wildlife movement. Construction Activity MM 4.3-4 The following guidelines shall be Less Than Significant implemented to minimize impacts on Impact.

Implementation of Mitigation Measure 4.3-4 would resources will remain less than significant. reduce these construction -related impacts to a less than significant level. A City -approved biologist shall be retained by the applicant as a construction monitor to ensure that incidental construction impacts on retained biological resources are avoided or minimized. Responsibilities of the construction monitor shall include the following: • Attend all pre -grading meetings to ensure that the timing and location of construction activities do not conflict with mitigation requirements. • Conduct meetings with the contractor and other key construction personnel, describing the importance of restricting work to within the project boundaries and outside of the preserved areas. The monitor shall also work with the contractor to determine the most appropriate staging/storage areas for equipment and materials. • Guide the contractor in marking/flagging the construction area limits, in accordance with the final Dockweiler Drive Alignment Project Final EIR 1. Executive Summary State Clearinghouse No. 2013082016 Page 1-18 City of Santa Clarita February 2018 Environmental Impacts Mitigation Measures Level of Significance After Mitigation approved grading plan. • Periodically and routinely visit the site during construction to coordinate and monitor compliance with the above provisions. The construction contractor shall install temporary erosion control measures to reduce impacts to and protect on site drainages from excess sedimentation, siltation, and erosion. These measures shall consist of minimization of existing vegetation removal; the use of temporary soil covers, such as hydro -seeding with native species, mulch/binder and erosion control blankets to protect exposed soil from wind and rain erosion; and/or the installation of silt fencing, berms, and dikes to protect storm drain inlets and drainages. No changing of oil or other fluids, or discarding of any trash or other construction waste materials shall occur on the Project Site. Vehicles carrying supplies, such as concrete, shall not be allowed to empty, clean out, or otherwise place materials into natural areas on or immediately adjacent to the site. Any equipment or vehicles driven and/or operated within or adjacent to drainages shall be checked and maintained daily, to prevent leaks of materials that if introduced to water Dockweiler Drive Alignment Project Final EIR 1. Executive Summary State Clearinghouse No. 2013082016 Page 1-19 City of Santa Clarita February 2018 Environmental Impacts Mitigation Measures Level of Significance After Mitigation could be deleterious to aquatic life. No equipment maintenance shall be conducted within the drainage channels or within 50 feet of channels. (Fuel -powered vehicles and equipment shall not be left idling or operated beyond periods need to accomplish approved tasks.) Construction personnel shall be prohibited from entry into areas outside the designated construction area, except for necessary construction related activities, such as surveying. All such construction activities in or adjacent to remaining open space areas shall be coordinated with the project biologist. Standard dust control measures of the South Coast Air Quality Management District shall be implemented to reduce impacts on nearby plants and wildlife. This includes a variety of options to reduce dust including replacing ground cover in disturbed areas as quickly as possible, watering active sites regularly, and suspending all excavating and grading operations during periods of high winds. Upon completion of construction, the contractor shall be held responsible to restore any haul roads, access roads, or staging areas that are outside of approved grading limits. This restoration shall be done in consultation with the project biologist. Dockweiler Drive Alignment Project Final EIR 1.

Removal of the fence shall occur only after the project arborist or qualified biologist confirms the health of preserved trees. (3) Stormwater and Urban Runoff No mitigation measures are required. Less than Significant Impact. It is expect that stormwater runoff would be limited to pavement runoff during periodic storm events. It is reasonable to assume runoff could substantially affect special -status species potentially occurring downstream from the Project Site (i.e. Newhall Creek), incrementally diminish habitat, and degrade the quality of the environment. With the compliance to City's standard stormwater requirements and required design criteria, impacts to Newhall Creek resulting from Stormwater runoff would be less than significant. Cultural Resources Cultural and Historic Resources No mitigation measures are required. Less than Significant Impact. No cultural or historic habitable structures are located on -site, and as such, the Project would not have the potential to adversely impact any historic or cultural resources.

Tribal Cultural Resources See MM 4.4-1, above. Less than Significant Impact. Based on a records search conducted through the South Central Coastal Information Center (SCCIC) (see Appendix E to this EIR), no archaeological sites have been identified within a '/z-mile radius of the Project Site. As such, the Proposed Project would not have a direct Dockweiler Drive Alignment Project Final EIR 1.

However, a lack of surface evidence of archeological resources does not preclude their subsurface existence. As such, provisions for the identification and evaluation of accidentally discovered archeological resources would be implemented in accordance with mitigation measure 4.4-1. With the incorporation of mitigation measure 4.4-1, impacts upon tribal resources would be less than significant. Geology/Soils MM 4.5-1 The Proposed Project shall be designed and Less Than Significant constructed in accordance with the City and Impact.

Dockweiler Drive Alignment Project Final EIR 1. Executive Summary State Clearinghouse No. 2013082016 Page 1-24 City of Santa Clarita February 2018 Environmental Impacts Mitigation Measures Level of Significance After Mitigation No oil wells have been drilled on or immediately adjacent to the Project Site. If any undocumented oil wells are encountered during future construction operations at the site, their location(s) should be surveyed and the current well conditions evaluated. Water wells have been drilled in the vicinity of the proposed road alignments. If one of these water well is within the proposed road alignment, or if a water well is encountered during future construction operations at the Project Site, the location should be surveyed and the potential impacts to well conditions should be evaluated. The implementation of Mitigation Measure 4.5-1 would insure that potential Project impacts would be reduced to a less than significant level. Hydrology/Water Quality Construction No mitigation measures are required. Less Than Significant Impact. During the construction phase, the typical pollutants that affect surface water quality are: sediment from soil erosion, petroleum products (gasoline, diesel, kerosene, oil and grease), hydrocarbons from asphalt paving, construction equipment leaks, paints and solvents, detergents, fertilizers, and pesticides. The Proposed Project would be required to prepare and implement a SWPPP prior to earthwork activities that will use best management practices and erosion control measures to prevent pollution in stormwater discharge. All Project construction activities would comply with the City's grading permit regulations, which require the implementation of grading and dust control measures, including a wet weather erosion control plan if construction occurs during rainy season, as well as inspections to ensure that sedimentation and erosion is minimized. Therefore, through compliance with NPDES requirements and City grading regulations, the Project's construction impacts related to water quality would not violate any water quality standards or waste discharge requirements or otherwise substantially degrade water quality. Construction -related impacts to hydrology and water quality would therefore be less than significant. Dockweiler Drive Alignment Project Final EIR 1. Executive Summary State Clearinghouse No. 2013082016 Page 1-25 City of Santa Clarita February 2018 Environmental Impacts Mitigation Measures Level of Significance After Mitigation Operation No mitigation measures are required. Less Than Significant Impact. Once the Project has been constructed, urban runoff could include the aforementioned contaminants, trace metals, landscape maintenance debris, dry product spills, and "nuisance flows" from landscape irrigation during the dry -season. In accordance with NPDES requirements, the Project Applicant would be required to have a Project -specific SUSMP in place during the operational life of the Project to address the management of runoff from the proposed roadway extension. The SUSMP would include site design, source control, low -impact development, and best management practices. Therefore, during the Project's operation implementation of the storm water quality plan would reduce water quality impacts to less than significant. Inundation and Flooding No mitigation measures are required. Less Than Significant Impact. A post -Project hydraulic model was analyzed to understand the impacts of inundation and flooding. The result of the post -Project hydraulic model indicate that the proposed bridge and channel improvements can accommodate the Capital Flood and will not create any flood hazard for the adjacent railroad and proposed street improvements Riprap and vegetation linings are recommended for the high and moderate shear zones, respectively. Impacts associated with inundation and flooding would be less than significant. Land Use/Planning No mitigation measures are required. Less Than Significant Impact. Implementation of the Proposed Project would not disrupt or physically divide an established community. Monument signage would properly guide traffic and identify the entrance to the Placerita Canyon community as a residential community with no through access. Additionally, the Project will provide increased pedestrian and vehicular access in the area. Dockweiler Drive Alignment Project Final EIR 1. Executive Summary State Clearinghouse No. 2013082016 Page 1-26 City of Santa Clarita February 2018 Environmental Impacts Mitigation Measures Level of Significance After Mitigation The Proposed Project would not conflict with any applicable land use plans, policies, or regulations, including: the Regional Transportation Plan / Sustainable Communities Strategy, City of Santa Clarita Municipal Code, City of Santa Clarita General Plan (including the Circulation Element), the Placenta Canyon Special Standards District and North Newhall Area, Old Town Newhall Specific Plan, and the Compass Blueprint Concept Plan. The Proposed Project would require the approval of an Oak Tree Permit and Hillside Review Permit at such time as development occurs or when funding of roadway construction becomes available. These entitlements will be obtained at such time as the proposed alignment is approved and roadway funding is available to implement the Project. With procurement of the required Oak Tree Permit and Hillside Review Permits, land use impacts would be less than significant. As such, Project implementation would create a less than significant impact with regards to land use and planning. Noise 4.8-1.

Construction and grading activities shall be 4.8-7 scheduled in such a way so as to avoid operating several pieces of equipment simultaneously, which causes high noise levels. Construction activities whose specific 4.8-8 location on the site may be flexible (e.g., operation of compressors and generators, cement mixing, general truck idling) shall be conducted as far as possible from the nearest noise -sensitive land uses, particularly away from single-family residences. Temporary construction noise barriers of 4.8-9 sufficient height shall be erected in such a way so as to disrupt line -of -sight between the active construction noise sources and any residences within 500 feet of the Project Site. No mitigation measures are required. Less Than Significant Operational — Roadway Noise Impacts The Proposed Project is anticipated to alter roadway traffic volumes as the Proposed Project would create a new roadway segment connecting Lyons Avenue to Dockweiler Drive. Locations in the vicinity of the Project Site could experience slight changes in noise levels as a result of the change in traffic patterns. The changes in future noise levels along the study -area roadway segments in the project vicinity are for the Proposed Project's near term (Year 2019) impacts would increase local noise levels by a maximum of 2.7 dBA CNEL (at the location of Dockweiler Drive (between Sierra Highway and Valle del Oro).

At all other roadway segments, the resulting noise levels are anticipated to decrease. As such the Proposed Project's potential to generate a substantial permanent increase in ambient noise levels in the project vicinity above levels existing without the project would be less than significant. The Future (2019) With Project noise levels on the new roadway segment from Lyons Avenue to Valle del Oro are expected to be 63.3 dBA (CNEL) within 50 feet of the centerline of the roadway. The resulting noise levels at the three identified sensitive receptors would be below 52.9 dBA. Thus, the anticipated with project noise levels at all off -site receptor locations would be within the "normally acceptable" range of noise for residential areas. Therefore, the Proposed Project's noise impacts would be less than significant. Operational Noise Levels — Railroad Crossing Bells No mitigation measures are required. Less Than Significant The closure of the existing at -grade railroad crossing at 13" Street would reduce the railroad warning signal bell levels in the vicinity of 13" Street and Railroad Avenue as the railroad crossing warning signal devices would be removed at this location and installed at a new at - grade crossing at Lyons Avenue and Railroad Avenue. The relocation of the existing railroad crossing signal at 13" Street and Railroad Avenue approximately 1,150 feet south to the Lyons Avenue and Railroad Avenue crossing would not result in a noticeable change to the ambient noise levels during train events. Noise impacts from at - grade warning signals would be less than significant.

Additions and Corrections to the Draft EIR State Clearinghouse No. 2013082016 Page 2-3 City of Santa Clarita February 2018 Santa Clarita re-examined the feasibility of an alternative route from Market Street to the proposed Dockweiler Drive roadway extension at The Master's University limits. In order for Dockweiler Drive to connect to Market Street and maintain a 6% profile, to comply with roadway standards for secondary highways, the join point on this profile would need to encroach on private property to connect to the terminus of existing Dockweiler Drive, which would conflict with the approved Masters University entitlements and site development design for the portion of the Dockweiler Drive extension that was approved in 2009. Such an alignment would necessitate a complete design change to the Masters University roadway plan, and may result in a change or revocation of the approved Master's University entitlements. Additionally, as shown in Figure 6.1-4 Market Street Alignment Plan and Profile and Figure 6.1-5, Market Street Alignment Geometric Plan, the proposed Dockweiler Drive extension would require a 92' right-of-way for Market Street from the crossing at Newhall Creek to Newhall Avenue to comply with roadway standards for secondary highways. Market Street is currently designated as a collector street with two through lanes and on -street parking. With the proposed 92-foot right-of-way, approximately 17 parcels (approximately 0.49 acres) on Market Street would require partial acquisition as well as improvements to the railroad crossing to facilitate the wider right-of-way and roadway improvements. The acquisition of parcels would include the Newhall Metrolink station and the City of Santa Clarita Newhall Community Center located on the north side of Market Street, residential properties on the south side of Market Street, the Veteran Memorial Plaza at the intersection of Newhall Avenue and Market Street, and additional land at the at -grade railroad crossing at Market Street. Additionally, commercial and residential properties and parking facilities along the north side and south side of Market Street west of Railroad Avenue would be acquired to accommodate the 92' right -of --way.

Market Street Alignment Geometric Plan. Under the Market Street Alternative Proiect. Market Street between Railroad Avenue and Newhall Avenue would be redesignated from a collector street to a secondary highway, and would facilitate traffic flow through the center of the Old Town Newhall community. This change would be in conflict with the City's adopted plans for the Old Town Newhall Specific Plan (ONSP), which was adopted to redevelop and revitalize the planning area to create a mixed use, transit -oriented, pedestrian -friendly, live -work -play environment, while taking advantage of proximate transit facilities. The ONSP re -designated San Fernando Road (Main Street) from a secondary highway to redirect traffic around the central Old Town Newhall area (by redirecting traffic flow to Newhall Avenue and Railroad Avenue) and proposed traffic calming measures to improve walkability and pedestrian safety throughout Old Town Newhall. This alternative would conflict with those objectives as it would create a secondary highway through the center of the district and would essentially divide the established business community of Old Town Newhall. The additional analvsis of the Market Street alternative concludes that despite meeting a 6% grade, this alternative remains infeasible because it would not align with the proposed and approved terminus of Dockweiler Drive to The Master's University. Additionally, this alternative would require the partial acquisition of 17 parcels, including the existing Newhall Metrolink Station and Newhall Community Center, to allow for a 92-foot right-of-way to Lyons Avenue/Dockweiler Drive Extension Project Final EIR 2. Additions and Corrections to the Draft EIR State Clearinghouse No. 2013082016 Page 2-7 City of Santa Clarita February 2018 comply with secondary highway roadway standards, which would disrupt the pedestrian - friendly character and transit oriented environment in Old Town Newhall, which is contrary to the objectives identified in the ONSP. Environmental Impacts The following provides additional analysis of the Market Street Alternative's impacts with respect to aesthetics, air quality, biological resources, cultural resources, geology and soils, hydrology and water quality, land use, noise and transportation and traffic. Aesthetics Temporary Construction Impacts The Market Street Alternative Project would similarly impact existing views and aesthetic character of the area by grading, stockpiles or debris and soil, building materials and construction equipment, all of which could occupy the field of view of passing motorists, pedestrians and nearby residents. The construction site would continue to be visible from the residential properties on Aden Avenue and from passing motorists on Lyons Avenue, Railroad Avenue, Market Street and Race Street. Thus, the existing visual character of the Project Site would be adversely impacted throughout the duration of the construction period. Therefore, impacts related to aesthetic character of the area during construction would be the same as compared to the Proposed Project, where impacts would be considered significant but temporary. Implementation of Mitigation Measure 4.1-1 would also be recommended for the Market Street Alternative Project. Long Term Operational impacts Upon completion of the Market Street Alternative Project the aesthetic character of the Project Site and its immediate surroundings would be permanent altered. Gradnrh proposed roadway extension would similarly alter views of the hillside portion of the Project Site. However, views of the intersection of Railroad Avenue and 13a' Street would remain unchanged, as the Market Street Alternative Project proposes no changes to the 13a' Street crossing. Similarly, the Market Street Alternative Project does not include the roadway extension between Dockweiler Drive and Lyons Avenue. As such, views of this intersection would largely remain unchanged, as compared to the Proposed Project. The Market Street Alternative may result in potentially significant impacts, with respect to views along Market Street and the visual character of the Old Town Newhall community. As shown in Figure 6.1-4 Market Street Alignment Plan and Profile and Figure 6.1-5, Market Street Alignment Geometric Plan, the proposed Dockweiler Drive extension would require a 92' right-of-way for Market Street from the crossing at Newhall Creek to Newhall Avenue to comply with roadway standards for secondary highways. Market Street is currently Lyons Avenue/Dockweiler Drive Extension Project Final EIR 2. Additions and Corrections to the Draft EIR State Clearinghouse No. 2013082016 Page 2-8 City of Santa Clarita February 2018 designated as a collector street with two through lanes and on -street parking. With the proposed 92-foot right-of-way, approximately 17 parcels (approximately 0.49 acres) on Market Street would require partial acquisition as well as roadway widening improvements to facilitate the wider right-of-way and roadway improvements. The acquisition of parcels would include the Newhall Metrolink station and the City of Santa Clarita Newhall Community Center located on the north side of Market Street, residential properties on the south side of Market Street, and the Veteran Memorial Plaza at the intersection of Newhall Avenue and Market Street. Additionally, as discussed further under the Cultural Resources subheading below, these improvements would require demolition of two buildings identified as having historic interest, along Market Street located at 24307 Railroad Avenue (Ye Olde Courthouse) and 24311-24313 Main Street (Frew Blacksmith Shop). Therefore, existing views of Market Street, from Newhall Avenue to Race Street, and the visual character of the Old Town Newhall community may be significantly altered to facilitate the development of a secondary highway. Alteration ofA Significant Ridgeline Similar to the Proposed Project, construction of the proposed roadway alignment between Dockweiler Drive and Market Street would permanently alter a significant ridgeline as designated in the City of Santa Clarita General Plan. However, as noted in Section 4.1, Aesthetics of the Draft EIR, the eastern segment of the Dockweiler alignment was previously approved under a separate project entitlement for The Master's University in 2009, which included a Ridgeline Alteration Permit for the eastern segment of this ridgeline.l As part of the approved entitlements for The Master's University Master Plan in 2009, the irreversible grading and re -contouring of the ridgeline was approved to the western limit of the Master's University Campus. The Market Street Alternative would have a slightly reduced grading footprint on the western portion of ridgeline leading to the Master's University Campus, as compared to the Proposed Project, as the Market Street Alternative does not include the extension of Dockweiler Drive to Lyons Avenue. Limited views of the altered portion of the ridgeline within the Market Street Alternative Project limits would be partially visible from the public rights -of -way along Market Street and Race Street. As a project design feature under this Alternative the grading plan would incorporate landform- grading practices to blend the manufactured slopes and required drainage benches into the natural topography to the maximum extent feasible. Plant materials will be utilized to protect slopes from slippage and soil erosion and minimize the visual effects of grading and construction on a hillside area. With approval of a Hillside Review Permit, aesthetic impacts associated with the grading of the Market Street Alternative Project would be reduced to less than significant levels.

Lyons Avenue/Dockweiler Drive Extension Project Final EIR 2. Additions and Corrections to the Draft EIR State Clearinghouse No. 2013082016 Page 2-9 City of Santa Clarita February 2018 Roadway Light and Glare Ambient nighttime lighting for the Market Street Alternative Project would be similar to that of the Proposed Project. The Market Street Alternative Project would introduce nighttime lighting to the Project Area, which will include pole -mounted streetlights at intersections and lighted bollards along Dockweiler Drive for public safety purposes, and would contribute to additional light and glare from the headlights of vehicles utilizing the roadway. Lighting uses associated with the Market Street Alternative Project are not anticipated to substantially impact any surrounding sensitive uses as the streetlights would be installed with downward directional fixtures and would not create light trespass onto any adjacent properties. Light emanating from the Market Street Alternative Project would be a relatively low-level indirect source of light illuminating the roadway and pedestrian walkways and would not adversely impact other properties in the immediate area. Overall, compliance with the design standards and requirements established in the Santa Clarita Municipal Code Section 17.51.050 would mitigate lighting impacts to a less than significant level. Therefore, impacts related to roadway light and glare would be less than significant. Air Quality Construction Construction of the Market Street Alternative Project would occur over an approximately 12-month timeframe and would involve clearing, grading, excavation, trenching, and asphalt paving. Sources of emissions during construction include: stationary and mobile uses of construction equipment, construction vehicles (heavy-duty construction vehicles and worker vehicles), and energy use. Additionally, earthwork and construction activities would generate fugitive dust emissions. These construction -related emissions and their associated air quality impacts would be short-term in nature and limited only to the period when construction activity is actively taking place. Although additional analysis would be required, it is reasonable to assume that the Market Street Alternative Project's construction emissions would be similar to the emissions generated under the Proposed Project. The increased emissions associated with the improvements to the existing portion of Market Street from Race Street to Newhall Avenue, to facilitate the development of a secondary highway, would be offset by the avoidance of grading associated with the Dockweiler to Lyons connection. As the Proposed Project emissions would be below SCAOMD's significance thresholds for all criteria pollutants, it is reasonable to assume that, similarly, the Market Street Alternative regional construction air quality emissions would be less than significant. AOMP Consistency The Market Street Alternative Project is consistent with the AOMP and would not interfere with attainment of air quality levels identified in the AOMP. Similar to the Proposed Project, Lyons Avenue/Dockweiler Drive Extension Project Final EIR 2. Additions and Corrections to the Draft EIR State Clearinghouse No. 2013082016 Page 2-10 City of Santa Clarita February 2018 the Market Street Alternative Project would help reduce congestion and vehicle miles traveled by providing sidewalks, bicycle lanes and direct access from the residential area and Master's University area to the Jan Heidt Newhall Metrolink Station and Old Town Newhall. The Market Street Alternative Project encourages alternative modes of transportation other than motor vehicles and would be consistent with the goals and objectives of the AOMP to reduce vehicle emissions throughout the Basin. Localized Construction Emissions Similar to the Proposed Project, the Market Street Alternative Project would result in significant localized air emissions in close proximity to residential land uses within 100 meters of the Project Site on a temporary and intermittent basis during construction. Localized NOx and CO emissions would be below the significance thresholds at all sensitive receptor locations. However, localized thresholds would be exceeded for PM,0 and PM2_5 emissions at two locations: (1) the single-family residential land uses located immediately north of the Project Site (within a proximity of 100 meters) and (2) the residential land uses within 100 meters of the Project Site in the vicinity of Market Street and Race Street. The Market Street Alternative would include the redevelopment of Market Street into a secondary highway, which would have increased adverse impacts to the residential land uses abutting Market Street between Race Street and Newhall Avenue. Therefore, notwithstanding implementation of mitigation measures 4.2-1 through 4.2-4, localized air quality impacts resulting from construction activities would be considered significant and unavoidable. Operational Emissions Although the Market Street Alternative Project would not directly generate any new vehicle trips, it would result in changes to the traffic circulation in the vicinity and would alter the average daily traffic volumes and peak hour traffic volumes at local intersections. A CO hotspot analysis was conducted for the Proposed Project and it was found that, under worst - case conditions, future CO concentrations at each intersection would not exceed the state 1- hour and 8-hour standards with or without the development of the Proposed Project. Because the projected roadway volumes under the Market Street Alternative Project are substantially consistent with the roadway volumes calculated under the Proposed Project, and the CO hotspot emissions under the Proposed project were substantially below the State's 1-hour and 8-hour CO standards, it is reasonable to assume that no significant project -related CO hotspot impact would occur relative to future carbon monoxide concentrations of the Market Street Alternative Project. The Market Street Alternative Project would therefore have a less than significant impact with respect to this criterion and impacts would be the same as the Proposed Project. Lyons Avenue/Dockweiler Drive Extension Project Final EIR 2. Additions and Corrections to the Draft EIR State Clearinghouse No. 2013082016 Page 2-11 City of Santa Clarita February 2018 Biological Resources Habitat Modification Vegetation The area of the Market Street Alternative was not surveyed for biological conditions as part of the Biological Survey conducted for the Proposed Project. However, based on prior biological surveys conducted in 2006 within the footprint of the Market Street Alternative project area for the Master's College Master Plan Draft EIR, vegetation communities that would be potentially impacted by the Market Street Alternative Project would primarily include Chamise Chaparral and Coast —Prickly -Pear Succulent Scrub. 2 A Biological Resources Assessment would need to be conducted for the Market Street Alternative to assess current on -site biological resources, the suitability of on -site habitats to support sensitive biological resources, and to analyze impacts to these resources As the Market Street Alternative's footprint is located in close proximity to the Proposed Proiect's footprint, it is reasonable to assume that mitigating potential adverse impacts related to habitat modification of onsite vegetation is feasible, which would result in a less than significant impact. Wildli e Similar to the Proposed Project, construction activity and grading operations of the Project Site for the Market Street Alternative Project would disturb and/or threaten the survival of common wildlife species present on -site. Similar to the Proposed Project, it is reasonable to assume that project implementation would not be expected to cause current wildlife population of common species on or adjacent to the Project Site to drop below self- sustaining levels. A Biological Resources Assessment would need to be conducted for the Market Street Alternative to assess current on -site biological resources, the suitability of site habitats to support sensitive biological resources, and to analyze impacts to these resources. As the Market Street Alternative's footprint is located in close proximity to the Proposed Project's footprint, it is reasonable to assume that mitigating potential adverse impacts related to habitat modification of wildlife is feasible, which would result in a less than significant impact. Project -related activities associated with site preparation and construction could result in the direct loss of individuals of one special -status wildlife species (the silvery legless lizard) and of active nests or the abandonment of active nests by adult birds should grading occur during nesting season. The loss of a California species of s edal concern and active bird nests would be a considered significant without mitigation. Implementation of mitigation measures 4.3-1 and 4.3-2 would reduce impacts to the silvery legless lizard and nesting birds to a less than significant level. The Master's College Master Plan Draft EIR, Figure 5.3-1, dated July 2008, and Final EIR, dated October 2008. SCHNo. 2004021002. Lyons Avenue/Dockweiler Drive Extension Project Final EIR 2. Additions and Corrections to the Draft EIR State Clearinghouse No. 2013082016 Page 2-12 City of Santa Clarita February 2018 Federally Protected Wetlands The Newhall Creek is a CDFW jurisdictional feature that occurs within the Project Site for the Market Street Alterative Project. The Market Street Alternative Project would result in both temporary and permanent impacts to the areas of the Newhall Creek and is classified as "riverine and related permanent water, with continuous flow at least seasonally." However, with the implementation of MM 4.3-3, which would be modified to account for the specific feet of bank stabilization specific to the Market Street Alternative, impacts to jurisdictional resources would be reduced to a less than significant level. Wildlife Movement and Corridors The Project Site for the Market Street Alternative is generally surrounded on three sides by development and road networks. However, Newhall Creek does extend through the Site and provides passage through developed areas between the Santa Clarita River and the Angeles National Forest to the southeast and is considered a part of a wildlife movement or migration corridor. Similar to the Proposed Project, the bridge spanning Newhall Creek at Market Street would be designed to limit impacts to wildlife movement and would serve to protect Newhall Creek as a functioning wildlife movement corridor. Therefore, the Market Street Alternative Project would not result in significant impacts to wildlife movement. Construction Activity Similar to the Proposed Project, construction -related activities, particularly site clearing, grading, and the implementation of the road surface, could have adverse effects on plant and wildlife habitat, and together, would be considered a significant impact. Implementation of Mitigation Measure 4.3-4 would reduce these construction -related impacts to a less than significant level. Overation Increase in Populations ofNon-Native Species Similar to the Proposed Project, non-native plants and wildlife are expected to increase on - site because these species are more adapt to urban environments and can out -compete native species. Historical and ongoing development in the vicinity of the Project Site has already supported continual and ongoing increase and proliferation of non-native plant and wildlife species in the vicinity of the Project Site. Development of the Market Street Alternative Project is not expected to substantially increase the distribution of non-native plants and wildlife. With compliance of Mitigation Measure 4.3-5, the Market Street Alternative Project impacts would be less than significant. Lyons Avenue/Dockweiler Drive Extension Project Final EIR 2. Additions and Corrections to the Draft EIR State Clearinghouse No. 2013082016 Page 2-13 City of Santa Clarita February 2018 Increased Light and Glare Similar to the Proposed Project, it is anticipated that nighttime lighting would increase m areas adjacent to the Project Site, which can disturb breeding and foraging behavior, movement, and can potentially alter breeding cycles of birds, mammals, and nocturnal invertebrates. Because of surrounding development around the Project Site, nearby natural areas already receive some nighttime lighting. The Market Street Alternative Project would increase light and glare effects near to the Newhall Creek corridor. Implementation of Mitigation Measure 4.3-6 would decrease this impact to a less than significant level. Stormwater and Urban Runoff Similar to the Proposed Project, it is expected that stormwater runoff would be limited to pavement runoff during periodic storm events. It is reasonable to assume runoff could substantially affect special -status species potentially occurring downstream from the Project Site (i.e. Newhall Creek), incrementally diminish habitat, and degrade the quality of the environment. With the compliance to City's standard stormwater requirements and required design criteria, impacts to Newhall Creek resulting from Stormwater runoff resulting from the Market Street Alternative Project would be less than significant. Cultural Resources Cultural and Historic Resources Under the Market Street Alternative Project, the proposed Dockweiler Drive extension would require a 92' right-of-way for Market Street from the crossing at Newhall Creek to Newhall Avenue to comply with roadway standards for secondary highways. Market Street is currently designated as a collector street with two through lanes and on -street parking. With the proposed 92-foot right-of-way, approximately 17 parcels (approximately 0.49 acres) on Market Street would require partial acquisition as well as improvements to the railroad crossing to facilitate the wider right-of-way and roadway improvements. Therefore, properties along Market Street, from Newhall Avenue to Race Street, may be altered to facilitate the development of a secondary highway. Based on a records search conducted through the South Central Coastal Information Center (SCCIC) (see Appendix E to the Draft EIR), two properties along Market Street have been identified as having historical interest. As shown in the Historic Resources Study Area, Figure 4.471, of the Draft EIR, these two properties are located at 24307 Railroad Avenue (Ye Olde Courthouse) and 24311-24313 Main Street (Frew Blacksmith Shop). Additional analysis would be required to examine the potentially significant adverse impacts with respect to the Market Street Alternative Project and the demolition of historical resources to accommodate the roadway standards for a secondary highway. Lyons Avenue/Dockweiler Drive Extension Project Final EIR 2. Additions and Corrections to the Draft EIR State Clearinghouse No. 2013082016 Page 2-14 City of Santa Clarita February 2018 Archaeological Resources Based on a records search conducted through the South Central Coastal Information Center SCCICI (see Appendix E to the Draft EIR), no archaeological sites have been identified within a'/2-mile radius of the Project Site. As the Market Street Alternative Project area falls within this '/2 mile search radius of the Proposed Project, the Market Street Alternative would not have a direct impact upon known archaeological resources. While, portions of the Project Site are improved with roadways, the Market Street Alternative Project will consist of earthwork activities, such as grading and excavation, in areas that are currently undeveloped. Construction -related earthwork activities may result in the accidental discovery of prehistoric or historic archaeological resources or Native American burial sites. Implementation of mitigation measures 4.4-1 will reduce impacts to a less than significant level. Paleontological Resources The records search conducted by the Vertebrate Paleontology Department of the Natural History Museum of Los Angeles County (See Appendix E to the Draft EIR) yielded no known fossil localities within the Project Site for the Proposed Project. The closest vertebrate fossil localities are from the Saugus Formation, located directly north of the Project Site. While it is possible that fossilized materials may be discovered during site preparation and construction for the Market Street Alternative, specifically grading and excavation activities, precautionary measures set forth in mitigation measure 4.4-2 would reduce any potential adverse impacts to paleontological resources to a less than significant level. Tribal Cultural Resources Similar to the Proposed Project, the Market Street Alternative Project would not have a direct impact upon known tribal cultural resources. Nevertheless, provisions for the identification and evaluation of accidentally discovered archeological resources would be implemented in accordance with mitigation measure 4.4-1. With the incorporation of mitigation measure 4.4-1, impacts upon tribal resources would be less than significant. Geology And Soils All slopes should be evaluated by the Project Geotechnical engineer at the planning and design stages for the Market Street Alternative. The hillside area of the site is designated on the State of California Seismic Hazard Zone Map to have earthquake -induced slope instability. Remedial measures will be required where ascending or descending cut slopes are not stable as determined by geologic or geotechnical stability analyses. Similar to the Proposed Project, it is reasonable to assume that the potential for earthquake -induced slope Lyons Avenue/Dockweiler Drive Extension Project Final EIR 2. Additions and Corrections to the Draft EIR State Clearinghouse No. 2013082016 Page 2-15 City of Santa Clarita February 2018 failures is considered low provided that future geologic and geotechnical evaluations and recommendations for slope stability are incorporated into design and construction. Additionally, specific recommendations for design and construction should be provided to address soil stability, including: hydro -compression, expansive soils, rippability, the handling of oversized material, soil corrosivity, shirking and bulking of materials, and the handling of the need for retaining wall. Additionally, if any undocumented oil wells are encountered during future construction operations at the site, their location(s) should be surveyed and the current well conditions evaluated. Water wells have been drilled in the vicinity of the proposed road alignments. If one of these water wells is within the proposed road alignment, or if a water well is encountered during future construction operations at the site, the location should be surveyed and the potential impacts to well conditions should be evaluated. Similar to the Proposed Project, the implementation of mitigation measures 4.5-1 and 4.5-2 would insure that potential Market Street Alternative Project impacts would be reduced to a less than significant level. Hydrology And Water Oualitv Construction During the construction phase, the typical pollutants that affect surface water quality are. sediment from soil erosion, petroleum products (gasoline, diesel, kerosene, oil and greasel, hydrocarbons from asphalt paving, construction equipment leaks, paints and solvents, detergents, fertilizers, and pesticides. Similar to the Proposed Project, the Market Street Alternative Project would be required to prepare and implement a SWPPP prior to earthwork activities that will put best management practices and erosion control measures to prevent pollution in stormwater discharge. All project construction activities would comply with the City's grading permit regulations, which require the implementation of grading and dust control measures, including a wet weather erosion control plan if construction occurs during rainy season, as well as inspections to ensure that sedimentation and erosion is minimized. Therefore, through compliance with NPDES requirements and City grading regulations, the Market Street Alternative Prcject's construction impacts related to water quality would not violate any water quality standards or waste discharge requirements or otherwise substantially degrade water quality. Construction -related impacts to hydrology and water quality would therefore be less than significant. Operation Once the Market Street Alternative Project has been constructed, urban runoff could include the aforementioned contaminants, trace metals, landscape maintenance debris, dry product s ills, and "nuisance flows" from landscape irrigation during the dry -season. In accordance with NPDES requirements, the Project Applicant would be required to have a Project - specific SUSMP in place during the operational life of the Project to address the management of runoff from the proposed roadway extension. The SUSMP would include Lyons Avenue/Dockweiler Drive Extension Project Final EIR 2. Additions and Corrections to the Draft EIR State Clearinghouse No. 2013082016 Page 2-16 City of Santa Clarita February 2018 site design, source control, low -impact development, and best management practices. Therefore, implementation of the storm water quality plan would reduce water quality impacts during the Market Street Alternative Project's operation to less than significant. Inundation and Flooding Similar to the Proposed Project, the Market Street Alternative Project would include a roadway extension from Market Street to Dockweiler Drive, which would span a portion of the Newhall Creek. As such, the Market Street Alternative Project would include the development of a new bridge across Newhall Creek and require embankment protection. Any improvements spanning Newhall Creek would be designed in accordance with current regulatory and State permitting agencies. A hydraulic and scour study would be required to examine the potential of adverse impacts with respect to hydrology under the Market Street Alternative. However, is it reasonable to assume that because the Market Street Alternative would have similar design parameters as the Proposed Project, with respect to crossing Newhall Creek, mitigating potential impacts related to inundation and flooding is feasible, which would result in a less than significant impact. Land Use And Planning As discussed above, under the Market Street Alternative Project, Market Street between Railroad Avenue and Newhall Avenue would be re -designated from a collector street to a secondary highway, and would facilitate traffic flow through the center of the Old Town Newhall community. This change would be in conflict with the City's adopted plans for the Old Town Newhall Specific Plan (ONSP), area which was adopted to redevelop and revitalize the planning area to create a mixed use, transit -oriented, pedestrian -friendly, live - work -play environment, while taking advantage of proximate transit facilities. The ONSP re -designated San Fernando Road (Main Street) from a secondary highway to redirect traffic around the central Old Town Newhall area (by redirecting traffic flow to Newhall Avenue and Railroad Avenue) and proposed traffic calming measures to improve walkability and pedestrian safety throughout Old Town Newhall. This alternative would conflict with those objectives as it would create a secondary highway through the center of the district and would essentially divide the established business community of Old Town Newhall. The Market Street Alternative would therefore result in a significant and unavoidable impact with respect to land use and planning. Noise Construction Similar to the Proposed Project, construction of the Market Street Alternative Project would require the use of heavy equipment for ground clearing, site grading, and roadway construction. Several pieces of construction equipment operating simultaneously would Lyons Avenue/Dockweiler Drive Extension Project Final EIR 2. Additions and Corrections to the Draft EIR State Clearinghouse No. 2013082016 Page 2-17 City of Santa Clarita February 2018 generate a noise level of approximately 94.6 dBA. The estimated construction noise levels impacting sensitive receptors are expected to exceed the City's daytime noise standards for residential uses (see Table 4.8-8 of the Draft EIR). The Market Street Alternative would directly abut the residential land uses along Market Street between Race Street and Newhall Avenue. As such it is reasonable to assume that the Market Street Alternative would result in higher noise levels at these sensitive receptors as compared to the Proposed Project. Similar to the construction noise impacts under the Proposed Project, the construction noise levels under the Market Street Alternative Project would result in a significant unavoidable impact. Operational Similar to the Proposed Project, the Market Street Alternative Project is anticipated to alter roadway traffic volumes as the Project would create a new roadway segment connecting Market Street to Dockweiler Drive. Locations in the vicinity of the Project Site could experience changes in noise levels as a result of the change in traffic patterns. The Market Street Alternative Project would direct more traffic through Market Street in lieu of the Dockweiler/Lyons Extension, which would not be constructed as part of this alternative. The land uses to the north and south of Market Street include residential properties, which are considered sensitive receptors with respect to noise impacts. The Market Street Alternative may therefore result in potentially significant operational noise impacts to these residential land uses, and as such, would be more impactful than the Proposed Project. Transportation and Traffic Analysis The City of Santa Clarita also re-examined the traffic impacts of an alternative route from Market Street to the proposed Dockweiler Drive roadway extension at The Master's University limits. The traffic study prepared for the Market Street alternative is incomorated in this Final EIR as Appendix B, Addendum Traffic Impact Analysis. Dockweiler Drive Alignment Proiect Alternative 3, Santa Clarita. CA, prepared by David Evans and Associates, January 4, 2018 ("Traffic Study Addendum"l. Existing Conditions As shown in Figure 6.1-6, the Market Street Alternative Project analyzed in the Traffic Study Addendum extends the Dockweiler Drive alignment to intersect with Market Street and Race Street. Based on potential traffic impacts to the area roadways, twenty intersections were identified for this analysis. Existing study intersections and traffic volumes are shown in Figure 6.1-7 and Figure 6.1-8, respectively. The traffic analysis was conducted with the existing intersection geometrics as shown in Figure 6.1-9. As presented in Table 6.1-2, Intersection Capacity Analysis — Existing Condition, most intersections are operating at LOS "E" or better. There are three intersections that are currently operating at LOS "F", which include, Sierra Highway and SR-14 Southbound Ramps, SR-1 Southbound Ramps and Newhall Avenue, and Market Street (EAST) and Newhall Avenue.

PARKER Figure 6.1-12 ENVIRONMENTAL CONSULTANTS Project Year 2019 With Market Street Alternative Intersection Geometrics City of Santa Clarita February 2018 As presented in Table 6.1-3 under Year 2019 with the Market Street Alternative Condition, most of the study intersections are anticipated to continue to operate at LOS E or better. Similar to the Proposed Project, four intersections are anticipated to operate at LOS F, they are: Sierra Highway and SR-14 Southbound Ramps, Sierra Highway and Placerita Canyon Road, SR-14 Northbound Ramps and Placerita Canyon Road, and SR-14 Southbound Ramps and Newhall Avenue. Under the Market Street Alternative, two additional intersections are anticipated to operate at LOS F, which would include: Newhall Avenue and Lyons Avenue and Market Street (East) and Newhall Avenue. With mitigation, the Sierra Highway and SR-14 Southbound Ramp intersection (Study Intersection 1) level of service would increase from LOS F to LOS C and LOS D during the AM and PM peak hours, respectively. With mitigation, the Sierra Highway and Placerita Canyon Road intersection (Study Intersection 2) level of service would increase from LOS D to LOS B and LOS F to LOS C during the AM and PM peak hours, respectively. With mitigation, the SR-14 Northbound Ramps and Placerita Canyon Road intersection (Study Intersection 3) level of service would increase from LOS B to LOS A and LOS F to LOS A during the AM and PM peak hours, respectively. With mitigation, the SR-14 Southbound Ramps and Newhall Avenue intersection (Study Intersection 5) level of service would increase from LOS F to LOS A and LOS E to LOS A during the AM and PM peak hours, respectively. With mitigation, Newhall Avenue and Lyons Avenue (Study Intersection I level of service would increase from LOS F to LOS C and LOS D to LOS C during the AM and PM peak hours, respectively. With mitigation, Market Street and Main Street (Study Intersection 21) level of service would increase from LOS B to LOS A and LOS D to LOS A during the AM and PM peak hours, respectively. Lastly, with mitigation, Market Street (East) and Newhall Avenue intersection (Study Intersection 22) level of service would increase from LOS D to LOS B and LOS F to LOS B during the AM and PM peak hours, respectively. With implementation of mitigation measures 6.1-1 through 6.1-11, summarized under the subheading Mitigation Measures (Market Street Alternative) on the following pages, the Market Street Alternative Project's impacts during the 2019 build -out year would be less than significant. Similar to the Proposed Project, the Market Street Alternative would include Mitigation Measures 4.9-1 and 4.9-6 through 4.9-9 (Refer to Section 4.9, Transportation and Traffic, of the Draft EIR). The Market Street Alternative Project would include mitigation measures 6.1-2 through 6.1-4, as identified on the following pages, in lieu of the Proposed Project's mitigation measures 4.9-2 through 4.9-5 for Year 2019 Project Mitigation. Additionally, the Market Street Alternative would not require implementation of Mitigation Measure 4.9-10 with respect to Year 2019 Regional Mitigation. Under the Market Street Alternative, Year 2019 project mitigation would include intersection modifications at Main Street (North - South) and Market Street (East-West). The intersection modifications would include installing a traffic signal. The north, south, east, and westbound directions would include a shared through -right turn lane. Intersection modifications at Newhall Avenue (North -South) Lyons Avenue/Dockweiler Drive Extension Project Final EIR 2. Additions and Corrections to the Draft EIR State Clearinghouse No. 2013082016 Page 2-28 City of Santa Clarita February 2018 and Market Street (East-West) would include removal of the traffic signal at the Newhall Avenue (North -South) and Market Street (West) intersection. The Newhall Avenue (North - South) and Market Street (East- West) intersections would be combined and converted to a multilane roundabout. The northbound direction would include a shared left -through lane and shared through -right lane. The southbound direction would include a left turn lane and a shared left -through -right lane. The eastbound and westbound directions would include a shared left -through -right lane. Future (2035) Conditions With Market Street Alternative Proiect The Santa Clarita Valley Consolidated Traffic Model (SCVCTM) for Build -Out Year provided traffic volumes for the Future Year 2035 with the Market Street Alternative Project. The model plots outlined the distribution of future traffic with the construction of the Market Street Alternative Project. The analysis of the Market Street Alternative Proiect utilizes the traffic volume projections for the City of Santa Clarita's traffic model together with the existing traffic flow data. The traffic projections are based on the General Plan Buildout. Like the Proposed Project, the buildout includes construction of future roadways Dockweiler Drive between Railroad Avenue and Valle Del Oro, Magic Mountain Parkway from Railroad Avenue to Via Princessa, Via Princessa between Claibourne Lane and Sheldon Avenue, and Santa Clarita Parkway. This also includes the proposed conceptual development of the North Newhall area (809 dwelling unit plus an approximate 11-acre commercial land use). The Future Year 2035 Market Street Alternative study intersections are provided in Figure 6.1-13 and the traffic volumes are provided in Figure 6.1-14. The intersections were analyzed using the capacity analysis methodology. The analysis was conducted with the Future Year 2035 Market Street Alternative Project Condition existing and mitigated study intersection geometrics illustrated in Figure 6.1-15. The LOS for the study intersections presented in Table 6.1-4 represents the LOS for the critical movement. This is typically the stop controlled left turn from the minor street. As presented in Table 6.1-4 under Future Year 2035 with the Market Street Alternative Project Condition, twelve of the study intersections are anticipated to operate at LOS F. Similar to the Project, four intersections that are anticipated to operate at LOS F, they are: Sierra Highway and Placerita Canyon Road, Sierra Highway and Newhall Avenue, Valle Del Oro and Dockweiler Drive, and Main Street and Newhall Avenue. Under the Market Street Alternative, eight additional intersections are anticipated to operate at LOS F, which would include: Sierra Highway and SR-14 Freeway Southbound Ramps, SR-14 Freeway Northbound Ramps and Placerita Canyon Road, SR-14 Freeway Southbound Ramps and Newhall Avenue, Railroad Avenue and Market Street, Newhall Avenue and Lyons Avenue, Railroad Avenue and 13a' Street, Market Street and Main Street, and Market Street (East) and Newhall Avenue. Mitigation measures are necessary to accommodate the anticipated Future Year 2035 traffic and reduce potential Market Street Alternative Project impacts.

With implementation of mitigation measures 6.1-1 through 6.1-11, summarized under the subheading Mitigation Measures (Market Street Alternative) on the following pages, the Market Street Alternative Project's impacts during the 2035 year would be less than significant. In summary, although the Market Street Alterative would ultimately result in less than significant impacts, it would result in slightly higher traffic delays in the general project area as compared to the Proposed Project. With mitigation, the Market Street Alternative is anticipated to reduce vehicle delays at 8 and 11 of the 16 study intersections analyzed during the A.M. and P.M. peak hours for the 2019 and 2035 buildout year scenarios, respectively when comparing the No Build scenario intersections to the Market Street Alternative intersections). However, with mitigation, the Proposed Project is anticipated to reduce Lyons Avenue/Dockweiler Drive Extension Project Final EIR 2. Additions and Corrections to the Draft EIR State Clearinghouse No. 2013082016 Page 2-34 City of Santa Clarita February 2018 vehicle delays at 9 and 12 of the 16 study intersections analyzed during the A.M. and P.M. peak hours for the 2019 and 2035 buildout year scenarios, respectively (when comparing the No Build scenario intersections to the Proposed Proiect intersections). Additionallv, the Market Street Alternative would result in slightly higher average daily traffic (ADT) along Lyons Avenue, Newhall Avenue and Railroad Avenue as compared to the Proposed Project for buildout year 2035. Under the Market Street Alternative for year 2035, Railroad Avenue (between 13a' Street and Lyons Avenue) would experience ADT of 36,200 vehicles, Lyons Avenue (between Main Street and Newhall Avenue) would experience ADT of 35,200 vehicles, and Newhall Avenue (between Lyons Avenue and Market Street) would experience ADT of 30,010 vehicles. Additionally, Newhall Avenue between Railroad Avenue and Valle Del Oro) would experience ADT of 47,700 vehicles. Under the Proposed Project for year 2035, Railroad Avenue (between 13a' Street and Lyons Avenue) would experience ADT of 32,700 vehicles, Lyons Avenue (between Main Street and Newhall Avenue) would experience ADT of 27,700 vehicles, and Newhall Avenue between Lyons Avenue and Market Street) would experience ADT of 26,100 vehicles. Additionally, Newhall Avenue (between Railroad Avenue and Valle Del Oro l would experience ADT of 44,500 vehicles. Therefore, under the Market Street Alternative, Railroad Avenue (between 13a' Street and Lyons Avenue) would experience a 10% increase in vehicles, Lyons Avenue (between Main Street and Newhall Avenue) would experience a 27% increase in vehicles, Newhall Avenue between Lyons Avenue and Market Street) would experience a 15% increase in vehicles and Newhall Avenue (between Railroad Avenue and Valle Del Oro) would experience a 7% increase in vehicles, as compared to the Proposed Project for buildout year 2035. The Proposed Project would therefore be more consistent with the goals of the Circulation Plan with respect to improving roadway level of service and the circulation network of the proiect area, as compared to the Market Street Alterative. Railroad Crossing Analysis Similar to the Proposed Project, a comparison of the No Build scenario, the Proposed Project scenario, and the Market Street Alternative Project scenario for Daily, AM and PM Peak hour traffic volumes were compiled for the Year 2019 and 2035 conditions as presented in Table 6.1-5 and Table 6.1-6, respectively. Existing conditions remain the same as reported in Section 4.9, Transportation and Traffic. As presented in Table 6.1-5 under the Market Street Alternative Year 2019, the total average daily railroad crossings is anticipated to be higher under the No Build Condition as compared to the Proposed Proiect and the Market Street Alternative Project. The Market Street Alternative Project total average daily railroad crossings would result in 910 fewer crossings than the No Build condition but would result in 4,660 more railroad crossings than the Proposed Project condition. As presented in Table 6.1-6 under The Market Street Alternative Year 2035, the total average daily traffic is Lyons Avenue/Dockweiler Drive Extension Project Final EIR 2.

Main Street, MS 16 Los Angeles, CA 90012 Date: October 9, 2017 COMMENT 1.1 Thank you for including the California Department of Transportation (Caltrans) in the environmental review process for the above referenced project. The project consists of an extension of Lyons Avenue from Railroad Avenue southeast to a proposed connection with Dockweiler Drive, to provide a T- intersection at Dockweiler Drive. Also included are [sic] a new at -grade railroad crossing east of Railroad Avenue and Lyons Avenue as well as an extension of Docweiler [sic] Drive and other various modifications on 13a' Street. RESPONSE TO COMMENT 1.1 This comment letter acknowledges that the California Department of Transportation ("Caltrans") has reviewed the DEIR for the Proposed Project and accurately restates the Project Description. No further response is required. Lyons Avenue/Dockweiler Drive Extension Project Final EIR 3. Responses to Comments State Clearinghouse No. 2013082016 Page 3-4 City of Santa Clarita February 2018 COMMENT 1.2 The nearest State facility to the project site is State Route 14. Caltrans does not expect project approval to result in direct adverse impacts to existing State transportation facilities. RESPONSE TO COMMENT 1.2 Caltrans acknowledges that project approvals are not expected to result in a direct adverse impact to existing State transportation facilities. This comment has been noted for the record, and no further response is required. COMMENT 1.3 Any transportation of heavy construction equipment and/or materials requiring use of oversized transport vehicles on State highways will require a Caltrans transportation permit. Caltrans recommends that large size truck trips be limited to off-peak commute periods. RESPONSE TO COMMENT 1.3 Caltrans's concerns have been noted for the record and will be forwarded to the decision makers for their consideration. Caltrans has discretionary authority with respect to the operation of vehicles or special mobile equipment of a size, weight, or load exceeding the maximum limitations specified in the California Vehicle Code. The Caltrans Transportation Permits Issuance Branch is responsible for the issuance of these special transportation permits for oversize/overweight vehicles on the State Highway System. Project contractors would adhere to obtaining necessary permits, including permits for the use of oversized vehicles. Additionally, the Proposed Project would incorporate the requirement to schedule heavy-duty truck trips outside of peak hours when possible has been incorporated as a mitigation measure. See Section 2, Additions and Corrections and Section 4, Mitigation Monitoring Program of the Final EIR. No further response is required. COMMENT 1.4 Also, storm water run-off is a sensitive issue for Los Angeles and Ventura counties. Be mindful that the project needs to be designed to discharge clean run-off water. RESPONSE TO COMMENT 1.4 The Proposed Project's impacts to hydrology, surface runoff and water quality were thoroughly evaluated and disclosed in Section 4.6 Hydrology and Water Quality, of the DEIR. As noted in the EIR, during the construction phase, the Proposed Project would be required to prepare and implement a Storm Water Pollution Prevention Plan ("SWPPP") prior to earthwork activities that will use best management practices and erosion control measures to prevent pollution in stormwater discharge. Through compliance with National Pollutant Discharge Elimination System ("NPDES") requirements and City grading regulations, the Project's construction impacts related to water quality would not violate any water quality Lyons Avenue/Dockweiler Drive Extension Project Final EIR 3. Responses to Comments State Clearinghouse No. 2013082016 Page 3-5 City of Santa Clarita February 2018 standards or waste discharge requirements or otherwise substantially degrade water quality. Additionally, in accordance with NPDES requirements, the Project Applicant would be required to have a Project - specific Standard Urban Stormwater Mitigation Plan ("SUSMP") in place during the operational life of the Project to address the management of runoff from the proposed roadway extension. The SUSMP would include site design, source control, low -impact development, and best management practices. Therefore, during the Project's construction and operation implementation of regulatory compliance would reduce water quality impacts to less than significant. No further analysis is required.

As noted, one comment letter was submitted by the State of California Public Utilities Commission ("CPUC"), which is included below as Comment Letter No. 3. No further response is required. COMMENT LETTER No. 3 State of California Public Utilities Commission Chi Cheung To, P.E. Utilities Engineer Rail Crossings and Engineering Branch, Safety and Enforcement Division 320 West 4tb Street, Suite 500 Los Angeles, CA 90013 Date: September 5, 2017 COMMENT 3.1 The California Public Utilities Commission (Commission) has jurisdiction over the safety of highway - rail crossings (crossings) in California. The California Public Utilities Code requires Commission approval for the construction or alteration of crossings and grants the Commission exclusive power on the design, alteration, grade separation and closure of crossings. The Commission's Rail Crossings and Engineering Branch (RCEB) is in receipt of the Draft EIR of the Lyons Avenue/ Dockweiler Drive Extension Project. The City of Santa Clarita (City) is the lead agency. As part of the project, the City proposes to create a new at -grade highway -rail crossing of the Los Angeles County Metropolitan Transportation Authority (Metro) tracks and Lyons Avenue, and potentially upgrade or close the at -grade crossing at 13a' Street, identified as CPUC crossing No. IO1VY-30.39 and DOT No. 746016J. Currently, the Southern California Regional Rail Authority (SCRRA) and the Union Pacific Railroad Company (UPRR) operate thirty passenger trains and nine freight trains over this line per day, respectively, at a maximum speed of 70 miles per hour. Lyons Avenue/Dockweiler Drive Extension Project Final EIR 3. Responses to Comments State Clearinghouse No. 2013082016 Page 3-7 City of Santa Clarita February 2018 RESPONSE TO COMMENT 3.1 This comment letter acknowledges that the CPUC has reviewed the DEIR for the Proposed Project. It should be noted that the Proposed Project, as analyzed in the DEIR, includes the closure of the at -grade crossing at 13th Street and Railroad Avenue. No further response is required. COMMENT 3.2 Any development adjacent to or near the railroad right of -way (ROW) should be planned with the safety of the rail corridor in mind. New developments will increase traffic volumes not only on streets and at intersections, but also at any adjacent at -grade rail crossing. Language should be in place so that any traffic impact studies undertaken should also address rail crossing safety analysis and associated proposed mitigation measures, including grade separation. RESPONSE TO COMMENT 3.2 As discussed in Section 2, Project Description, of the DEIR, the Proposed Project includes the addition of an at -grade rail crossing at the current terminus of Lyons Avenue and the Southern Pacific Railroad line and extension of a roadway connection from Lyons Avenue to Dockweiler Drive. The Proposed Project also includes the closure of an at -grade crossing east of the intersection of Railroad Avenue and 13'b Street. The new at -grade crossing would be built to meet all safety requirements and standards. Improvements would include such features as, but not limited to: • New railroad signal house; • Crossing Panels; • Advance Preemption and railroad signal design; • Pedestrian gates (4); • Railroad related signing, striping and legends; • Blank out sign for northbound traffic making right turn into the eastbound Lyons Avenue; • New fencing for railroad; • New driveway to access railroad property for maintenance; • New vehicular gates (6); and • New railroad loops. To clarify, the Proposed Project does not include the construction of any residential, commercial or industrial land uses that would directly create traffic. Rather, the Proposed Project includes the extension of Dockweiler Drive to facilitate a new east -west connection for the Santa Clarita Valley. The Proposed Project is subject to CPUC approval, and as such, the Proposed Project will comply with all applicable construction -related and operational rail crossing safety requirements, including those listed above in this comment. With respect to grade separation analyses, please refer to Response to Comment 3.3 below. No further analysis is required. Lyons Avenue/Dockweiler Drive Extension Project Final EIR 3. Responses to Comments State Clearinghouse No. 2013082016 Page 3-8 City of Santa Clarita February 2018 COMMENT 3.3 The Commission has adopted the Federal Railroad Administration's (FRA) policy to reduce the number of at -grade crossings on freight or passenger railroad mainlines in California. RCEB issued a comment letter in 2009 opposing the grade crossing alternative at Lyons Avenue and a second comment letter issued in 2015 after reviewing the City's Grade Separation Analysis with the same conclusion. While RCEB applauds the City's efforts to upgrade or close the 131h Street crossing, RCEB staff remains consistent in our position and opposes the at -grade option at Lyons Avenue due to the following reasons: • Accident history reveals grade crossings located adjacent to a parallel highway and four -legged intersections are prone to accidents; • Lyons Avenue will be utilized as a major local arterial between Interstate 5 Freeway and State Route 14, therefore traffic volume and roadway function are not comparable to the existing 131h Street crossing; • Existing railroad mainline contains heavy train traffic, with intercity commuter and freight trains operating in high speed; • The grade separation options have not been demonstrated as impracticable at this location. RESPONSE TO COMMENT 3.3 With respect to safety, as discussed above, the Proposed Project is subject to CPUC approval and as such the Proposed Project will comply with all applicable construction -related and operational rail crossing safety requirements, including those listed above in Response to Comment 3.2. With respect grade separation analyses, two alternatives were identified in the DEIR (Refer to Section 6.1 Project Alternatives), but were ultimately rejected as infeasible during the scoping process. The two grade separation alternatives considered but rejected included (1) extending Lyons Avenue to Dockweiler Drive with a bridge over the railroad right-of-way and (2) extending Lyons Avenue to Dockweiler Drive with a below grade underpass under the railroad right-of-way. The physical constraints associated with each of these alternatives led to them being rejected are summarized below. Lyons Avenue Overpass Extension to Dockweiler Drive The Lyons Avenue Overpass Extension to Dockweiler Drive was considered as a potential option to provide a direct connection from Lyons Avenue to Dockweiler Drive without an at -grade crossing. An illustration of the Lyons Avenue connection to Dockweiler Drive with an overpass crossing Railroad Avenue and the railroad right-of-way is shown in Figure 6.1-2, Lyons Avenue Overpass Alignment (see page 6.1-2 of the DEIR). In order to provide sufficient vertical clearance for the passing trains, Lyons Avenue would be raised approximately 30' above the railroad tracks. Two connections via Walnut Street / 9'h Street and Walnut Street / IIth Street between Lyons Avenue and Railroad Avenue would be established to replace the existing intersection. As concluded in the DEIR, in addition to adverse impacts to traffic, circulation, utilities and schools (see page 6.1-4 of the DEIR), most of the properties adjacent to Lyons Avenue, Walnut Street, 9th Street and Lyons Avenue/Dockweiler Drive Extension Project Final EIR 3. Responses to Comments State Clearinghouse No. 2013082016 Page 3-9 City of Santa Clarita February 2018 1 lth Street (shown as pink shading on Figure 6.1-2 of the DEIR), would be fully acquired for the grade separation option due to change of grade on Lyons Avenue and loss of access routes. The adjacent residents and businesses would be relocated. In addition, the grade separation option is not consistent with the City's Old Town Newhall Specific Plan. The grade separation would divide the community and cause an unnecessary burden to the residents within the impacted area. Additionally, raising Lyons Avenue over Railroad Avenue, the railroad tracks, and Newhall Creek would physically bisect the existing Newhall community and create a disconnect to the properties on either side of Lyons Avenue. Especially for residents living south of Lyons Avenue, it would require more effort to get to the Old Town Newhall Library on the north side of Lyons Avenue. The front view of the library would be blocked by a retaining wall supporting the roadway embankment of the grade separation. Additionally, 24 parking stalls in the library parking lot would be lost due to the necessary widening on Railroad Avenue for the grade separation. Because this alternative would be disruptive to the existing established community of Old Town Newhall and for the reasons addressed above, this alternative was rejected from further consideration. Lyons Avenue Underpass Extension to Dockweiler Drive The Lyons Avenue Underpass Extension to Dockweiler Drive was considered as another alternative to provide a direct connection from Lyons Avenue to Dockweiler Drive without an at -grade crossing. An illustration of the Lyons Avenue connection to Dockweiler Drive with an underpass crossing Railroad Avenue, the railroad right-of-way, and Newhall Creek is shown in Figure 6.1-3, Lyons Avenue Underpass on page 6.1-6 of the DEIR. As shown in Figure 6.1-3, a roadway bridge for Railroad Avenue, a railroad bridge for railroad tracks and a water bridge for the creek are needed for the underpass. In order to maintain enough vertical clearance from the underpass to the soffits of the bridges, the underpass near the railroad tracks would be approximately 28' below the existing ground. To maintain traffic circulation between Lyons Avenue and Railroad Avenue, two loop connectors via Walnut Street and I Vh Street to the north, and Walnut Street and 9th Street to the south, would be needed. Minor streets such as Main Street will be cul-de-sacs at Lyons Avenue. For the underpass alternative, a bridge to carry storm water from Newhall Creek would be required so the lowered Lyons Avenue could pass underneath. However, Newhall Creek is a natural flood control channel, instead of a man-made water channel such as the California Aqueduct where flow volume is controlled. The amount of storm water flowing though the bridge would be hard to predict. If a large storm occurred with excess stormwater than the bridge could handle, the underpass would be flooded, and traffic would be interrupted. Moreover, the bridge or the underpass would be susceptible to damage during larger storm events. Similar to the overpass alternative described above, the underpass alternative would be equally disruptive to the existing established community with respect to traffic circulation, relocation of utilities, impacts to Newhall Elementary School, and community disruption as described above for the Lyons Avenue overcrossing alternative. Therefore, for these reasons the underpass alternative was rejected from further consideration. Lyons Avenue/Dockweiler Drive Extension Project Final EIR 3. Responses to Comments State Clearinghouse No. 2013082016 Page 3-10 City of Santa Clarita February 2018 COMMENT 3.4 If the City intends to move forward with the at -grade option, a formal application must be made to the Commission. The normal timeframe for a formal proceeding usually varies from eight (8) to twelve (12) months but can be longer if the application is contested and evidentiary hearings are held. Please be advised that based on site -specific conditions, train traffic and information provided by the City, RCEB will protest the grade crossing application. If you have any questions, please contact Chi Cheung To at (213) 576-5766.

COMMENT LETTER No. 6 County of Los Angeles Sheriffs Department Robert J. Lewis, Captain Santa Clarita Valley Station Date: October 9, 2017 COMMENT 6.1 The Santa Clarita Valley Station (Station) reviewed the Notice of Availability of a Draft Environmental Impact Report (DEIR), dated August 16, 2017, for the Lyons Avenue/ Dockweiler Drive Extension Project (Project). The Proposed Project is located in the Newhall community of the City of Santa Clarita (City), and includes the extension of Lyons Avenue from Railroad Avenue to Dockweiler Drive; the addition of a new at -grade railroad crossing east of the Railroad Avenue and Lyons Avenue intersection; the extension of Dockweiler Drive at The Master's University; and the closure of an existing at -grade railroad crossing at the intersection of 13a' Street and Railroad Avenue. The proposed Project does not include residential, commercial, industrial and other habitable types of development. RESPONSE TO COMMENT 6.1 This comment letter acknowledges that the County of Los Angeles Sheriffs Department Santa Clarita Valley Station ("LASD") has reviewed the DEIR for the Proposed Project and accurately restates the Project Description. No further response is required. COMMENT 6.2 The proposed Project is intended to relieve existing and projected traffic congestion by reconfiguring, abandoning and/or extending certain street segments, relocating an existing at -grade railroad crossing, and Lyons Avenue/Dockweiler Drive Extension Project Final EIR 3. Responses to Comments State Clearinghouse No. 2013082016 Page 3-14 City of Santa Clarita February 2018 creating dedicated pedestrian and bicycle lanes. The Station generally supports these types of public improvements because they typically create well-defined separations between vehicular pedestrian, and rail traffic, often resulting in fewer collisions, injuries and damages to personal and private property. Such improvements also tend to contribute to an overall positive impact on law enforcement patrol operations, emergency access, and response times. The Proposed Project also excludes residential, commercial, office, industrial and other habitable types of development that affect the resident, workforce, and visitor populations of the Station's service area. Accordingly, the Station expects the proposed Project to have a less than significant impact on the demand for law enforcement services we provide. RESPONSE TO COMMENT 6.2 LASD's comments are consistent with the findings of the DEIR as discussed in Section 5.1 Impacts Determined to be Less Than Significant, page 5.1-3, subheading Fire and Police Protection. No further analysis is required. COMMENT 6.3 DEIR Section 4.9 contains detailed analyses of potential Project —related impacts on local traffic and circulation systems, and concludes that such impacts will be less than significant following implementation of mitigation measures described in Section 4.9.5. The Station does not dispute the information or findings contained in the DEIR. However, we are concerned with construction -related traffic because of potentially significant impacts on commuters, pedestrians, emergency responders, and our patrol operations. The Station recommends the preparation of a construction traffic management plan, requests advanced notification of temporary lane closures, realignments, etc., and requires the provision of one or more emergency lane through the Project site at all times. RESPONSE TO COMMENT 6.3 In response to LASD's concerns regarding construction, the Proposed Project will require a Construction Management Plan, which shall be submitted to the City of Santa Clarita Public Works Department (Traffic and Transportation Division) and LASD Santa Clarita Valley Station for review and approval prior to the commencement of any construction. The plans shall show the location of any roadway or sidewalk closures, traffic detours, haul routes, hours of operation, protective devices, warning signs and access to abutting properties, and if applicable, the location of off -site staging areas for haul trucks and construction vehicles, and provide one or more emergency lane through the Project site at all times. All construction related traffic shall be restricted to off-peak hours. The County of Los Angeles Sheriffs Department Santa Clarita Valley Station shall receive advance notice prior to any changes in temporary lane closures or realignments. See Section 2, Additions and Corrections and Section 4, Mitigation Monitoring Program of this Final EIR. No further response is required. Lyons Avenue/Dockweiler Drive Extension Project Final EIR 3.

COMMENT LETTER No. 7 Los Angeles County Metropolitan Transportation Authority (METRO) Derek Hull, Manager, Transportation Planning One Gateway Plaza Los Angeles, CA 90012 Date: October 16, 2017 COMMENT 7.1 Thank you for the opportunity to comment on the Notice of Availability of a Draft EIR for the Lyons Avenue/Dockweiler Drive Extension Project located on the City of Santa Clarita. This letter conveys recommendations from the Los Angeles County Metropolitan Transportation Authority (Metro) concerning issues that are germane to our agency's statutory responsibility in relation to our facilities and services that may be affected by the proposed project. Metro is committed to working with stakeholders across the County to support the development of transit - oriented communities (TOCs). TOCs are built by considering transit within a broader community and creating vibrant, compact, walkable and bikeable places centered around transit stations and hubs with the goal of encouraging the use of transit and other alternatives to driving. Metro looks forward to collaborating with local municipalities, developers, and other stakeholders in their land use planning and development efforts, and to find partnerships that support TOCs across Los Angeles County. Project Description The Proposed Project includes: the extension of Lyons Avenue from Railroad Avenue southeast to the proposed connection with Dockweiler Drive, to provide a T-intersection at Dockweiler Drive; the addition of a new at -grade railroad crossing east of the Railroad Avenue and Lyons Avenue intersection; and the extension of Dockweiler Drive from the approved extension a [sic] the Master's University (The Master's University extension of Dockweiler Drive through the Master's University property was approved and evaluated under a separate EIR) northwest to connect with the intersection of Arch Street and 12a' Street. Lyons Avenue/Dockweiler Drive Extension Project Final EIR 3. Responses to Comments State Clearinghouse No. 2013082016 Page 3-16 City of Santa Clarita February 2018 RESPONSE TO COMMENT 7.1 This comment letter acknowledges that the Los Angeles County Metropolitan Transportation Authority (Metro) has reviewed the DEIR for the Proposed Project and accurately restates the Project Description. No further response is required. COMMENT 7.2 Metro Comments Metrolink Adjacent It is noted that the proposed project would extend Lyons Avenue across an existing LACMTA-owned Railroad Right-of-way (ROW). ROW is operated and maintained by the Southern California Regional Rail Authority (SCRRA) to run the Metrolink commuter rail service and Union Pacific Railroad freight trains also operate on this line. SCRRA will be providing separate comments, however, the following concerns related to the project's proximity to the ROW should be addressed in the EIR: 1. The project sponsor is advised that rail service operates in both directions and that trains may operate, in and out of revenue service, 24 hours a day, seven days a week, in the ROW adjacent to the proposed project. RESPONSE TO COMMENT 7.2 The DEIR recognizes the Southern California Regional Rail Authority (SCRRA) as a responsible Agency in the DEIR. SCRRA has submitted a letter on the DEIR, which is referenced below as Comment Letter No. 9. Response to the SCRRA comment letter are provided below. This comment has been noted for the record and requires no additional analysis with respect to the DEIR. COMMENT 7.3 2. The policy adopted by the SCRRA Board of Director stipulates that if a new at grade crossing is developed, one or more existing at -grade crossings in the area must be closed. RESPONSE TO COMMENT 7.3 The Proposed Project includes the addition of a new at -grade crossing immediately east of the intersection of Lyons Avenue and Railroad Avenue and the closure of an at -grade crossing to the immediate east of the intersection of 13a' Street and Railroad Avenue. As such, the Proposed Project would be consistent with this policy and no further analysis is required. COMMENT 7.4 3. It should be noted that railroad crossings are under jurisdiction of the California Public Utility Commission (CPUC). The project sponsor will be required to obtain the necessary Lyons Avenue/Dockweiler Drive Extension Project Final EIR 3. Responses to Comments State Clearinghouse No. 2013082016 Page 3-17 City of Santa Clarita February 2018 authorization to construct the crossing. This will include demonstrating that a grade separation crossing is not practical. RESPONSE TO COMMENT 7.4 The DEIR acknowledges CPUC as a Responsible Agency. CPUC has submitted a comment letter on the DEIR, which is referenced above as Comment Letter No. 3. Responses to CPUC's letter are provided above. With respect to the grade separation analyses as presented in the DEIR, please refer to Response to Comment 3.3 above. No further response is required. COMMENT 7.5 4. It is likely that this proposed crossing will include the addition of warning devices, traffic signal modifications, and rail road signaling modifications. These modifications, along with the necessary use of train horns will bring additional noise factors as a result of the project. RESPONSE TO COMMENT 7.5 With respect to noise, as discussed in Section 4.8 Noise, of the DEIR, the relocation of the existing railroad crossing signal at 13a' Street and Railroad Avenue (approximately 1,150 feet south to the Lyons Avenue and Railroad Avenue crossing) would not result in a noticeable change to the ambient noise levels during train events. Therefore, the Proposed Project's noise impacts would be less than significant and no further analysis is required. COMMENT 7.6 5. All project development, engineering, and construction efforts must be coordinated with LACMTA Regional Rail, LACMTA Real Estate, and the SCRRA. RESPONSE TO COMMENT 7.6 The DEIR identifies LACMTA and SCRRA as Responsible Agencies. Therefore, the construction of the Proposed Project shall be conducted in coordination with the aforementioned agencies. No further response is required. COMMENT 7.7 6. Any work Performed on the project infrastructure or property requiring access to the railroad ROW, shall be covered by specific Right -of -Entry permits with specific requirements. These may include permits for construction of infrastructure, and any future repairs, painting, graffiti removal, etc., including the use of overhead of cranes or any other equipment that could potentially impact railroad operations and safety. Frequent access for maintenance tasks such as graffiti removal, will necessitate an active license agreement. This agreement will include an annual license fee, and other requirements that meet safety standards for access to a ROW with active rail operations.

Responses to Comments State Clearinghouse No. 2013082016 Page 3-18 City of Santa Clarita February 2018 RESPONSE TO COMMENT 7.7 The Proposed Project is subject to LACMTA, CPUC and SCRRA approval and as such the Proposed Project will comply with all applicable construction -related and operational rail crossing safety requirements, including those listed above in this comment. No further analysis is required. COMMENT 7.8 7. Considering the proximity of the proposed project to the railroad ROW, trains will produce noise, vibration and visual impacts. A recorded Noise Easement Deed in favor of Metro is required, a form of which is attached. The easement recorded in the Deed will extend to successors and tenants, as well. In addition, any noise mitigation required for the project will be borne by the developers of the project and not Metro or the operating railroads. RESPONSE TO COMMENT 7.8 The Proposed Project is subject to LACMTA approval and as such the Proposed Project will comply with all applicable construction -related and operational requirements, including those listed above in this comment. No further analysis is required. COMMENT 7.9 Active Transportation For Option B of the intersection improvements for Arch Street/12a' Street/ Placerita Canyon and proposed Dockweiler Drive: Roundabout design shall accommodate people on bicycles. Refer to AASHTO's Guide for the Development of Bicycle Facilities (2012) for consideration of bicycle travel at roundabouts (§4.12.11). RESPONSE TO COMMENT 7.9 In the event Option B, as identified in the DEIR is selected, the roundabout would be designed in accordance with the appropriate design features and standards to accommodate bicyclists. The Proposed Project would be subject to the site plan review requirements of the City of Santa Clarita. No further analysis is required. COMMENT 7.10 Congestion Management Program Beyond impacts to Metro facilities and operations, Metro must also notify the applicant of state requirements. A Transportation Impact Analysis (TIA), with roadway and transit components, is required under the State of California Congestion Management Program (CMP) statute. The CMP TIA Guidelines are published in the "2010 Congestion Management Program for Los Angeles County," Appendix D (attached). The geographic area examined in the TIA must include the following at a minimum: Lyons Avenue/Dockweiler Drive Extension Project Final EIR 3. Responses to Comments State Clearinghouse No. 2013082016 Page 3-19 City of Santa Clarita February 2018 1. All CMP arterial monitoring intersections, including monitored freeway on/off-ramp intersections, where the proposed project will add 50 or more trips during either the a.m. or p.m. weekday peak hour (of adjacent street traffic). 2. If CMP arterial segments are being analyzed rather than intersections, the study area must include all segments where the proposed project will add 50 or more peak hour trips (total of both directions). Within the study area the TIA must analyze at least one segment between monitored CMP intersections. 3. Mainline freeway -monitoring locations where the project will add 150 or more trips, in either direction, during either the a.m. or p.m. weekday peak hour. 4. Caltrans must also be consulted through the NOP process to identify other specific locations to be analyzed on the state highway system. The CMP TIA requirement also contains two separate impact studies covering roadways and transit, as outlined in Sections D.8.1- D.9.4. If the TIA identifies no facilities for study based on the criteria above, no further traffic analysis is required. However, projects must still consider transit impacts. For all CMP TIA requirements please see the attached guidelines. RESPONSE TO COMMENT 7.10 With respect to a Congestion Management Program (CMP) Transportation Impact Analysis (TIA), the Proposed Project does not include the development of residential, commercial, industrial or other habitable types of development that would generate additional vehicle trips. Rather, the Proposed Project includes implementation of a roadway extension that was previously identified and approved as part of the City's Circulation Element and analyzed and adopted as part of the One Valley One Vision (OVOV) 2010 EIR. With respect to the traffic analysis component of the CMP TIA, the Proposed Project would include the extension of Lyons Avenue from its existing terminus at Railroad Avenue on the west to the future Master's University Master Plan Dockweiler extension to the east of railroad crossing, which would be consistent with the Circulation Element. As concluded in the Circulation Element, the traffic model conducted for the OVOV EIR indicated that all designated CMP roadway segments within the planning area would operate at level of service (LOS) "E" or better at buildout of the City's General Plan and the County's Area Plan. In conformance with the CMP, the maximum acceptable level of service on CMP roadways within the OVOV Planning Area is LOS "E". Therefore, the Circulation Element is consistent with the Congestion Management Plan. The traffic analysis conducted for the Circulation Element utilizes the Santa Clarita Valley Consolidated Traffic Model (SCVCTM). This traffic model produces peak hour and average daily trips (ADT) forecasts for the OVOV area roadway system. Buildout land use data from the proposed City General Plan and County Area Plan Land Use Elements was used as the basis for the traffic forecasts. Consistent with the methodology utilized in the Circulation Element, the traffic analysis for the Proposed Project was also based on the SCVCTM. (Refer also to Traffic Impact Analysis: Dockweiler Drive Alignment Project, Santa Clarita, CA, prepared by David Evans and Associates, dated August 8, 2017, included in Appendix H of the DEIR). As concluded in Section 4.9 Transportation and Traffic of the DEIR, under the future Lyons Avenue/Dockweiler Drive Extension Project Final EIR 3. Responses to Comments State Clearinghouse No. 2013082016 Page 3-20 City of Santa Clarita February 2018 year 2035 Proposed Project condition (See Table 4.9-7 Intersection Capacity Analysis - Year 2035 with Proposed Project Condition, page 4.9-26 of the DEIR), with mitigation all study intersections analyzed for the Proposed Project are anticipated to operate at LOS "E" or better. Additionally, as shown below, the Proposed Project is largely consistent with the anticipated LOS for arterial roadway segments, as analyzed in the OVOV EIR, for the buildout of the proposed City General Plan and County Area Plan. The roadway segments listed below for the Proposed Project would operate at LOS "E" or above. Under the Proposed Project, two roadway segments, Newhall Avenue north of Valle Del Oro and Newhall Avenue north of Sierra Highway, would experience slightly higher ADT as compared to the OVOV plan, and one roadway segment, Sierra Highway north of Dockweiler Drive, would experience slightly less ADT as compared to the OVOV plan. Because the Proposed Project includes a roadway extension and thus would not be generating any new trips, an increase in ADT at one roadway segment would generally be offset by a corresponding decrease of ADT at another intersection.

Responses to Comments State Clearinghouse No. 2013082016 Page 3-21 City of Santa Clarita February 2018 While circulation patterns would differ under the buildout of the proposed roadway extension scenario as compared to a "No Build" scenario, the addition of trips in the project vicinity is anticipated to occur as buildout of the general plan continues. Therefore, the Proposed Project would be consistent with the CMP analysis presented in the Circulation Element and a less than significant impact upon the affected CMP roadway segments would occur. With respect to freeway impacts, under the No Build Scenario for year 2035, SR-14 would experience ADT of approximately 255,900 vehicles. Under the Proposed Project for buildout year 2035, SR-14 would a slight decrease in ADT of approximately 249,500 vehicles.

COMMENT LETTER No. 9 Southern California Gas Company James Chuang, Senior Environmental Specialist 555 Fifth Street Los Angeles, CA 90013 Date: September 15, 2017 COMMENT 9.1 Southern California Gas Company (SoCalGas) appreciates the opportunity to review and respond to the Draft Environmental Impact Report (DEIR) for the Lyons Avenue/Dockweiler Drive Extension Project. SoCalGas understands that the proposed project would involve an extension of Lyons Avenue from Railroad Avenue southeast to connect with Dockweiler Drive, creating a T-intersection. The project would also include the addition of a new at -grade railroad crossing east of the Railroad Avenue and Lyons Avenue intersection, as well as another extension of Dockweiler Drive from the approved extension at The Master's University northwest to connect with the intersection of Arch Street and 12th Street. RESPONSE TO COMMENT 9.1 This comment letter acknowledges that the Southern California Gas Company ("SoCalGas") has reviewed the DEIR for the Proposed Project. No further response is required. COMMENT 9.2 We respectfully request that the following comments be incorporated in the administrative record for the DEIR: • SoCalGas has several underground facilities in the area that the proposed road extension would traverse. These include a high-pressure transmission line 24 inches in diameter, at the Lyons Avenue/Railroad Avenue intersection. Several medium pressure distribution lines located at the Lyons Avenue/Railroad Avenue intersection and along 12th Street and Placerita Canyon Road where the proposed extension would cross. • SoCalGas recommends that the project proponent call Underground Service Alert at 811 at least two business days prior to performing any excavation work for the proposed project. Underground Service Alert will coordinate with SoCalGas and other Utility owners in the area to mark the locations of buried utility -owned lines. Lyons Avenue/Dockweiler Drive Extension Project Final EIR 3. Responses to Comments State Clearinghouse No. 2013082016 Page 3-24 City of Santa Clarita February 2018 • Should it be determined that the proposed project may require SoCalGas to abandon and/or relocate or otherwise modify any portion of its existing natural gas lines, SoCalGas respectfully requests that the County and/or the project proponent coordinate with us by calling (800) 427- 2000 for Non-residential to follow-up on this matter. RESPONSE TO COMMENT 9.2 While impacts to utilities were determined to be less than significant (refer to Section 5.1 Impacts Determined to be Less Than Significant of the DEIR), the Final EIR will include mitigation to ensure that locations of buried utility -owned lines are marked prior to commencement of excavation work for the Proposed Project. Additionally, mitigation will be incorporated into the Final EIR to ensure that the abandonment and/or relocation and/or modification of any portion of an existing natural gas lines is coordinated with SoCalGas. See Section 2, Additions and Corrections, of this Final EIR. The addition of these mitigation measures does not change the impact conclusion with respect to utilities. No further analysis is warranted. COMMENT 9.3 Once again, we appreciate the opportunity to comment on the DEIR. If you have any questions, please feel free to contact SoCalGas Environmental Review at Envreview@semprautilities.com or (213) 244- 5817. RESPONSE TO COMMENT 9.3 This comment letter has been included in the record and will be forwarded to the decision makers for their consideration. No further response is required. COMMENT LETTER No. 10 The Southern California Regional Rail Authority (SCRRA) Roderick Diaz, Director Planning & Development One Gateway Plaza, 12th Floor Los Angeles, CA 90012 Date: October 16, 2017 COMMENT 10.1 The Southern California Regional Rail Authority (SCRRA) has received the above noted DEIR for the Lyons Avenue/Dockweiler Drive Extension Project. Thank you for the opportunity to comment on key issues relative to SCRRA and operations of the railroad that crosses the project location. As background information, SCRRA is a five -county Joint Powers Authority (JPA) that operates the regional commuter rail system known as Metrolink. Additionally, SCRRA provides rail engineering, construction, operations and maintenance services to its five JPA member agencies. The JPA consists of the Los Angeles County Metropolitan Transportation Authority (METRO), San Bernardino County Lyons Avenue/Dockweiler Drive Extension Project Final EIR 3. Responses to Comments State Clearinghouse No. 2013082016 Page 3-25 City of Santa Clarita February 2018 Transportation Authority (SBCTA), Orange County Transportation Authority (OCTA), Riverside County Transportation Commission (RCTC) and Ventura County Transportation Commission (VCTC). The railroad right of way where the project is located is owned by Metro and operated, dispatched and maintained by SCRRA. The Lyons Avenue extension project (as proposed) would be located at railroad milepost 30.16 on our Valley Subdivision rail line. Currently, there are 30 Metrolink commuter trains and 5 Union Pacific (UPRR) freight trains that pass this location on a daily basis. RESPONSE TO COMMENT 10.1 This comment letter acknowledges that the Southern California Regional Rail Authority ("SCRRA") has reviewed the DEIR for the Proposed Project. No further response is required. COMMENT 10.2 As this project involves a new at -grade crossing proposal of the very active rail line we offer the following initial comments: 1. Noise from warning devices and train horns will be generated from creation of new at - grade crossing. Trains operate 7 days a week and 24 hours a day. Trains do generate noise both from operations and also from Federal requirements to sound their horn as warning to pedestrians and motorists when approaching at -grade crossings. RESPONSE TO COMMENT 10.2 While this comment does not raise specific concerns with respect o the environmental analysis of the DEIR, nonetheless, as disclosed in Section 4.8 Noise, of the DEIR, the relocation of the existing railroad crossing signal at 13a' Street and Railroad Avenue (approximately 1,150 feet south to the Lyons Avenue and Railroad Avenue crossing) would not result in a noticeable change to the ambient noise levels during train events. Therefore, the Proposed Project's noise impacts would be less than significant. No further analysis is required. COMMENT 10.3 2. SCRRA's adopted policies discourage the creation of new at -grade cossings. [sic] SCRRA has adopted Resolution 98-21 Regarding Highway -Rail Grade Crossings (Exhibit A) and a new SCRRA Highway -Rail Grade Crossings Recommended Design Practices and Standards Manual. In Chapter 7.4 of the manual it states that "Before considering a new highway -rail grade crossing, the first alternative that should always be considered is a grade -separated crossing." In Resolution 98-21 it states in Item 2 that SCRRA shall oppose the creation of new rail- highway grade crossings to the extent feasible on all regional passenger rail lines. Item 6 of the same resolution states that The SCRRA would support the creation of a new rail -highway grade crossing only if improvements to other grade crossings, including elimination of grade crossing(s), are made part Lyons Avenue/Dockweiler Drive Extension Project Final EIR 3. Responses to Comments State Clearinghouse No. 2013082016 Page 3-26 City of Santa Clarita February 2018 of the creation of the new grade crossing which together clearly improve public convenience and safety. In order for SCRRA to even consider the possibility of supporting a new at -grade crossing the City would have to prove that adequate mitigation measures would be in place to make the new crossing application package safer than what exists today. A closure of a smaller less used at -grade crossing for a new larger multi -lane at -grade crossing (1 for 1 swap) does not prove that the overall safety factor for all crossings would be increased. A clear "reduction in risk" for SCRRA and member agency Metro must be clearly shown. Your DEIR only shows closing 13a' Street and opening of a new multi -lane crossing of Lyons Avenue. Other safety mitigation measures could include the closure of other at -grade crossings within the city's jurisdiction, and upgrade of other existing at -grade crossings to the latest standards as noted in the Design Manual (refer to SCRRA's previous letter response to NOP of DEIR dated 10-22-13 for possible other safety mitigations). RESPONSE TO COMMENT 10.3 With respect to safety, the Proposed Project is subject to SCRRA approval and as such the Proposed Project will comply with all applicable construction -related and operational rail crossing safety requirements, including those listed Section 2, Project Description of, the DEIR. Refer also to Response to Comment 3.2, above. Additionally, the Alternative 2 Project, which was identified as the Environmentally Superior Alternative, as discussed in Section 6.4 and Section 6.5 of the DEIR, would include infrastructure and traffic improvements to the intersection of 13a' Street and Railroad Avenue and the at -grade crossing to accommodate the proposed extension of Dockweiler Drive to Arch Street. Under this alternative, Lyons Avenue would not be extended and the current terminus would remain. As such, no new crossing would occur. This comment has been noted for the record and will be forwarded to the decision makers for their consideration. No further response is required. COMMENT 10.4 3. A formal application to the California Public Utilities Commission (CPUC) needs to be made with letters of concurrence from all stakeholders (Metro, SCRRA and UPRR). The CPUC has ultimate jurisdiction for approval of new at- grade crossings in California. Our preference at this time would be that a grade separated crossing proposal be put in place in lieu of the at -grade option. RESPONSE TO COMMENT 10.4 A formal application for the Proposed Project will be submitted to the CPUC. With respect grade separation analyses, two alternatives were identified in the DEIR (Refer to Section 6.1 Project Alternatives), but were ultimately rejected as infeasible during the scoping process. The two grade separation alternatives considered but rejected included (1) extending Lyons Avenue to Dockweiler Drive with a bridge over the railroad right-of-way and (2) extending Lyons Avenue to Dockweiler Drive with a below grade underpass under the railroad right-of-way. The physical constraints associated with each of these alternatives led to them being rejected. Please refer also to Response to Comment 3.3 above.

Responses to Comments State Clearinghouse No. 2013082016 Page 3-27 City of Santa Clarita February 2018 comment has been noted for the record and will be forwarded to the decision makers for their consideration. No further response is required. COMMENT 10.5 4. At -grade crossing creates operational and safety issues. The location of the proposed crossing would traverse 2 tracks in the immediate vicinity of an SCRRA control point (CP Hood). The location of the crossing signals and gates could impact line of sight for train engineer needing to see the controlling signals for CP Hood to move from one track to another. This potential operational issue could force relocation or modifications to the control point at city's expense. RESPONSE TO COMMENT 10.5 With respect to safety, the Proposed Project is subject to SCRRA approval, and as such, the Proposed Project will comply with all applicable construction -related and operational rail crossing safety requirements, including those listed Section 2, Project Description, of the DEIR. Refer also to Response to Comment 3.2, above. This comment has been noted for the record and will be forwarded to the decision makers for their consideration. No further response is required. COMMENT 10.6 5. A new at -grade crossing so close to an existing station could present additional traffic impacts when the trains are sitting in the station. The gates would either stay down or have to time-out and go back up when the train is stopped in the station. A thorough analysis would have to be done to determine if an at -grade crossing is feasible within the control point location. The traffic impacts if the gates remain in the down position to the new intersection should be studied. This type of situation exists at other Metrolink station locations near crossings and does present some safety concerns and complaints. RESPONSE TO COMMENT 10.6 The Proposed Project would include a new at -grade crossing at the proposed extension of Lyons Avenue from Railroad Avenue. The Proposed Project would include the closure of the existing at -grade crossing at 13th Street and Railroad Avenue. The new crossing would be located approximately 0.25 mile north of the existing at -grade crossing located at Market Street. Similar to existing conditions, the Proposed Project would not provide access between Dockweiler Drive to Market Street. Therefore, in the event that railroad gates are in a down position at the new crossing at Lyons Avenue, when a train is stopped at the Metrolink station to the south, the traffic on Market Street would remain unaffected by the new at -grade crossing. Additionally, under the Alternative 2 Project, the 13t'' Street at -grade crossing would remain and no at -grade crossing would occur at Lyons Avenue and Railroad Avenue. As such, future conditions would be similar to existing conditions at 13t'' Street under the Alternative 2 Project, with respect to when a train is stopped at the Metrolink station to the south. The Proposed Project is subject to SCRRA approval and as such the Proposed Project will comply with all applicable operational rail crossing safety improvements and technology with respect to control point locations, crossing signals and gates to Lyons Avenue/Dockweiler Drive Extension Project Final EIR 3. Responses to Comments State Clearinghouse No. 2013082016 Page 3-28 City of Santa Clarita February 2018 minimize disruptions to both vehicular, pedestrian and train circulation. No further analysis of this issue is warranted at this time. COMMENT 10.7 6. Pedestrian safety and potential trespassing issues to and from the Newhall Station should be considered in the design of Lyons Avenue extension. An additional safety concern would be the fact that the shortest route for pedestrians using the new proposed crossing to get to the station would be to trespass into the railroad right of way from the sidewalk and off the ends of the existing platforms. Trespassing in the right of way to or from the station would need to be addressed. RESPONSE TO COMMENT 10.7 With respect to safety the Proposed Project is subject to SCRRA approval and as such the Proposed Project will comply with all applicable construction -related and operational rail crossing safety requirements, including those listed Section 2, Project Description, of the DEIR.

RESPONSE TO COMMENT 11.1 The Placerita Canyon Property Owner's Association ("PCPOA") has submitted a comment letter on the Proposed Project, responses to their concerns are provided below. No further response is required. Lyons Avenue/Dockweiler Drive Extension Project Final EIR 3. Responses to Comments State Clearinghouse No. 2013082016 Page 3-29 City of Santa Clarita February 2018 COMMENT 11.2 We have always favored the Market Street connection and continue to do so. Here's what we favor: bring Dockweiler, as planned, down to Arch or Pine. Instead of having traffic bear right to 13a' Street crossing, have it bear left to Market Street. Market Street is an already -improved crossing. Traffic can go right, left or straight. It leads both to Railroad for north and south travel or directly into Downtown Newhall. RESPONSE TO COMMENT 11.2 As disclosed in the DEIR in Section 6.1, the Market Street Alternative was rejected from further consideration due to the physical constraints associated with grading, as well as the Alternative's incompatibility with respect to public safety and local residential street standards (See Section 6.1, page 6.1-2 of the DEIR). Specifically, this alternative was rejected from further consideration due to the resulting 11.15% gradient of the roadway profile resulting from the existing topographical gradient between Market Street and Dockweiler Drive and the relatively sharp curve at the base of an incline where the alignment would connect to Market Street. A gradient of 11.15% would not meet the street standards of a secondary highway and would potentially result in unsafe roadway conditions. Additionally, Market Street is a local residential street that directly abuts and provides access to single and multi -family residential land uses. The proposed alignment of Dockweiler Drive through this existing residential neighborhood would not be consistent with the alignment identified within the Circulation Element and would not be compatible with respect to public safety and local residential street standards. This alternative alignment was rejected as infeasible. As further discussed in Response to Comment 12.38 below, and in Section 2 Additions and Corrections, under additional Market Street analysis, in response to public comments, the City of Santa Clarita re- examined the feasibility of an alternative route from Market Street to the proposed Dockweiler Drive roadway extension at The Master's University limits. Despite meeting a 6% grade, this alternative remains infeasible because it would not align with the proposed and approved terminus of Dockweiler Drive to The Master's University. Furthermore, this alternative would require the partial acquisition of 17 parcels, including the existing Newhall Metrolink Station, the Newhall Community Center and the Veteran Memorial Plaza to allow for a 92-foot right-of-way to comply with secondary highway roadway standards, which would disrupt the pedestrian -friendly character and transit oriented environment of Market Street, which is contrary to the objects identified in the Old Town Newhall Specific Plan. Therefore, the Market Street Alternative would actually result in increased impacts with respect to land use and planning impacts. Refer also to Response to Comment 11.3 below. The commenter's opinion has been noted for the record and will be forwarded to the decision makers for their consideration. No further response is required.

It has many drawbacks: • It floods easily. • It is often overcrowded with long waits. • It does not lead directly to any destination. • Traffic waiting to turn in from the north often lines up past 141` Street cutting off a lane of traffic on Railroad. • The U-turn allowed from the north further impedes access. RESPONSE TO COMMENT 11.3 The commenter's concerns with respect to the existing conditions observed at the intersection of 13th Street and Railroad Avenue are noted for the record. Additionally, the Alternative 2 Project, which was analyzed in Section 6.4 of the DEIR, would include infrastructure and traffic improvements to accommodate the proposed extension of Dockweiler Drive and improve vehicle and pedestrian safety and circulation, similar to the Proposed Project. As shown in Figure 6.4-2 (see page 6.4-3 of the DEIR), the existing westbound travel lanes on 13th Street approaching Railroad Avenue would be improved with two westbound lanes and a median, with one dedicated left turn lane, one shared through lane and left turn lane, and one dedicated right turn lane. The eastbound traffic lanes on 13th Street would be improved to provide two through travel lanes. The existing median nose on Railroad Avenue would be removed to reconfigure the four southbound lanes to provide two protected left turn lanes, one dedicated through lane and one shared right turn lane and through lane. The northbound lanes on Railroad Avenue would provide two through lanes, one protected left turn lane and one protected right turn lane. Additionally, Alternative 2, with implementation of mitigation, would result in reduced vehicle delays during A.M. and P.M. peak hours at the intersection of Railroad Avenue and 13'h Street as compared to the No Build Conditions for both the 2019 and 2035 buildout year scenarios. This comment has been included in the record and will be forwarded to the decision makers for their consideration. No further analysis with respect to the environmental analysis is warranted. COMMENT 11.4 The 13th Street crossing is within Placerita Canyon's Special Standards District in which the City guarantees our rural equestrian neighborhood. Directing more traffic into the Special Standards District will require a General Plan Amendment. Lyons Avenue/Dockweiler Drive Extension Project Final EIR 3. Responses to Comments State Clearinghouse No. 2013082016 Page 3-31 City of Santa Clarita February 2018 RESPONSE TO COMMENT 11.4 The 13a' Street crossing is an already existing intersection. The Alterative 2 Project would include infrastructure and traffic improvements to accommodate the proposed extension of Dockweiler Drive to Arch Street and improve vehicle and pedestrian safety and circulation. The commenter does not provide substantial evidence, pursuant to Public Resources Code Section 21080(e) (2), to support their assertion that the Alternative 2 Project is in conflict or inconsistent with the provisions of the PCSSD. As disclosed in the DEIR, similar to the Proposed Project, the Alternative 2 Project would be in compliance with the applicable standards identified in the PCSSD. Additionally, as discussed above in Response to Comment 11.3, Alternative 2, with implementation of mitigation, would result in reduced vehicle delays during A.M. and P.M. peak hours at the intersection of Railroad Avenue and 13'h Street as compared to the No Build Conditions for both the 2019 and 2035 buildout year scenarios. Therefore, no further analysis with respect to the DEIR is warranted. COMMENT 11.5 Please choose the simplest and best alternative and take the Dockweiler traffic down to Arch or Pine and then over to Market Street. RESPONSE TO COMMENT 11.5 As disclosed in the DEIR in Section 6.1, the Market Street Alternative was evaluated and rejected from further consideration due to the physical constraints associated with grading, as well as the Alternative's incompatibility with respect to public safety and local residential street standards (See Section 6.1, page 6.1-2 of the DEIR). See also Response to Comment 12.38, below, and Section 2. Additions and Corrections, Market Street Alignment Additional Analysis. This comment has been noted for the record and will be forwarded to the decision makers for their consideration. The commenter does not raise a specific issue with respect to the environmental analysis presented in the DEIR, and as such no further response is required. COMMENT 11.6 Our horse people are adamant — no roundabout, unsafe!! [sic] That's been stated for years! RESPONSE TO COMMENT 11.6 In the event "Option B", as identified in the DEIR (See Figure 2-12) is selected, the traffic circle would be designed in accordance with the appropriate design features and standards and would be subject to the site plan review requirements of the City of Santa Clarita. No further analysis is required. Lyons Avenue/Dockweiler Drive Extension Project Final EIR 3. Responses to Comments State Clearinghouse No. 2013082016 Page 3-32 City of Santa Clarita February 2018 COMMENT LETTER No. 12 Law Offices, Graham • Vaage LLP Arnold K. Graham 801 North Brand Boulevard, Suite 1180 Glendale California 91203 October 13, 2017 COMMENT 12.1 Re: Objection by Placerita Canyon Property Owner's Association to the Lyons Avenue DEIR Proposed At -Grade Rail Crossing and its relationship to the Dockweiler Drive Alignment Project (`Dockweiler Project') Dear Mayor Smyth and Council Members: This office represents the interests of the Placerita Canyon Property Owner's Association ("PCPOA") and its members in regard to their opposition to the above -referenced proposed Lyons Avenue At -Grade Rail Crossing Project ("Lyons Avenue Project"), and its nexus to the proposed Dockweiler Project. The Lyons Avenue Project is required to be tied to the proposed Dockweiler Project. RESPONSE TO COMMENT 12.1 This comment identifies the commenter and its representation of the PCPOA's interests and objection to the Proposed Project. The commenter's assertion that there is a nexus between the previously proposed Lyons Avenue At -Grade Rail Crossing Project ("Lyons Avenue Project") and the proposed Lyons Avenue/Dockweiler Drive Extension Project (the "Proposed Project") is incorrect. For clarification, the Lyons Avenue At -Grade Rail Crossing Project DEIR was prepared in 2010 as a staged EIR to evaluate the impacts of an at -grade rail crossing at Lyons Avenue and the closure of the 13th Street at -grade rail crossing. The Lyons Avenue At -Grade Rail Crossing Project DEIR did not propose or analyze connecting Lyons Avenue to Dockweiler Drive. That DEIR was published in March 2010 but was never completed or certified as a Final EIR. In response to public comments on the Lyons Avenue At -Grade Rail Crossing Project DEIR, the City decided to abandon that project for the Proposed Dockweiler Drive Extension Project. Due to the length of time that had lapsed between the circulation of the DEIR for the Lyons Avenue At -Grade Crossing EIR, and substantial revisions and analysis entailed with the revised project, the City decided to proceed with an entirely new project and issued a Notice of Preparation (NOP) in August 2013. As such, the proposed Lyons Avenue/Dockweiler Drive Extension Project is a stand-alone Project EIR and does not tier off of the previous DEIR prepared for the Lyons Avenue At -Grade Rail Crossing Project. Responses to the commenter's concerns with respect to CEQA are provided below. COMMENT 12.2 As a first point, the Dockweiler Project is neither wanted nor needed especially by that sector of the Santa Clarita that will be the most significantly and severely adversely impacted, namely, PCPOA. Lyons Avenue/Dockweiler Drive Extension Project Final EIR 3. Responses to Comments State Clearinghouse No. 2013082016 Page 3-33 City of Santa Clarita February 2018 RESPONSE TO COMMENT 12.2 The commenter's opinion has been noted for the record and will be forwarded to the decision -makers for their consideration. No further response with regards to the DEIR is warranted. COMMENT 12.3 The approval of the Dockweiler Project and the Lyons Avenue Crossing Project are in derogation to the protections intended by the Placerita Canyon Special Standards District, enacted "to protect, maintain, preserve and enhance the secluded, rural equestrian character of the community." In fact, if and when constructed, the Dockweiler Project will eviscerate the protections intended Placerita Canon [sic] Special Standards District to protect the community against uncontrolled development in the future, and to protect against harm and damage to the existing community, its structures, and its residents. RESPONSE TO COMMENT 12.3 With respect to the commenter's reference to the Lyons Avenue Crossing Project, see Response to Comment 12.1. The commenter's assertion that Proposed Project would violate the protections guaranteed by the PCSSD is not substantiated. The commenter has not provided any specific examples of how the Project is in conflict or inconsistent with the provisions of the PCSSD, which are established in Chapter 17.39.020, of the Santa Clarita Municipal Code (SCMC). As disclosed in the DEIR, the Proposed Project was properly identified as being located in the PCSSD. Additionally, the DEIR included a detailed analysis evaluating the consistency of the Proposed Project to the specific applicable development standards for the PCSSD area. As analyzed in Section 4.7, Table 4.7-3, page 4.7-18, of the DEIR, the Proposed Project is in substantial compliance with the standards identified in the PCSSD. Therefore, no further analysis with respect to the DEIR is warranted. COMMENT 12.4 The City is proposing to construct the Proposed Dockweiler Drive Alignment Project directly through the heart and in violation of the Placerita Canyon Special Standards District, by extending Dockweiler Avenue to extend it to Lyons Avenue, across the SCRRA railroad tracks, essentially connecting Sierra Highway (even though it will never be connected to an onramp to the 14 Freeway because it is too close to the existing freeway connections at Placerita Canyon and Newhall Avenue), by formalizing Dockweiler into becoming a major bypass to divert and redirect tens of thousands of cars daily from the 14 Freeway directly through the Placerita Special Standards District, across the proposed Lyons Avenue Crossing, and into the commercial center of Santa Clarita, then connecting on to the 1-5 Freeway. (See previous report of Arthur L. Kassan, P.E., dated May 26, 2010, submitted by PCPOA, incorporated herein by this reference.) RESPONSE TO COMMENT 12.4 This comment describes the Proposed Project's alignment of Dockweiler Drive to Lyons Avenue. As noted in the DEIR, the proposed connection and extension of Lyons Avenue to Dockweiler Drive is Lyons Avenue/Dockweiler Drive Extension Project Final EIR 3. Responses to Comments State Clearinghouse No. 2013082016 Page 3-34 City of Santa Clarita February 2018 identified in the Circulation Element of the City's General Plan as one of the primary east -west arterials through the City of Santa Clarita that would provide a through connection from Sierra Highway to Railroad Avenue. The purpose of the EIR is to analyze the environmental impacts that would result from the construction and operation of the Proposed Project and analyze alternatives to the Proposed Project that may be effective in reducing or avoiding environmental impacts. With respect to the incorporation of the letter prepared by Arthur L. Kassen in 2010 (in response to the Lyons Avenue At -Grade Crossing EIR), see Response to Comment 12.1, above. With respect to the Proposed Project's consistency with PCSSD, please refer to Response to Comment 12.3 above. The commenter does not raise specific issues with respect to the DEIR for the Proposed Project and as such, no further analysis is required. COMMENT 12.5 The City attempts to sanctify the intended Dockweiler Project in conjunction with the Lyons Avenue Project premised on its contention that they are consistent with the General Plan which, of course, presupposes that the General Plan was flawless, which it clearly is not because it never proffered a specific combined Dowkweiler / Lyons Project [sic] which was subjected or has met current CEQA standards. The City has admitted such in its DEIR.' RESPONSE TO COMMENT 12.5 With respect to the General Plan, as disclosed and analyzed in the DEIR, the extension of Dockweiler Drive is identified in the Circulation Element as a major new roadway. The extension, as proposed in the Circulation Element, would complete the approved roadway connection from Railroad Avenue to Sierra Highway. The Proposed Project includes the extension of Lyons Avenue from Railroad Avenue to the approved alignment of Dockweiler Drive at The Master's University site. The Master's University extension of Dockweiler Drive through The Master's University property was evaluated under a separate EIR (The Master's College Master Plan DEIR, dated July 2008, and Final EIR, dated October 2008. SCH No. 2004021002), and approved in 2009. As shown in Section 4.7, Table 4.7-2 on page 4.7-10, the Proposed Project would be in substantial compliance with the goals, objectives, and policies of the Circulation Element. The footnote referenced by the commenter is a mischaracterization of the text as it appears in the DEIR. The text is in reference to the Market Street Alignment, not the Proposed Project, as suggested by the commenter. The residential community referenced in this text is located immediately south of Market Street. The paragraph in its entirety is located in Section 6.1 Introduction, page 6.1-2, of the DEIR: "The proposed alignment of Dockweiler Drive through this existing residential neighborhood would not be consistent with the alignment identified within the Circulation Element and would not be compatible with respect to public safety and local residential street standards" Lyons Avenue/Dockweiler Drive Extension Project Final EIR 3. Responses to Comments State Clearinghouse No. 2013082016 Page 3-35 City of Santa Clarita February 2018 "Additionally, Market Street is a local residential street that directly abuts and provides access to single and multi family residential land uses. The proposed alignment of Dockweiler Drive through this existing residential neighborhood would not be consistent with the alignment identified within the Circulation Element and would not be compatible with respect to public safety and local residential street standards. For this reason, this alternative alignment was rejected as infeasible. " Furthermore, it should be noted that the Market Street alignment was considered but dismissed as a feasible project alternative as it would result in increased environmental impacts as compared to the Proposed Project. Pursuant to Section 15126.6(c) of the CEQA Guidelines, "the range of potential alternatives to the proposed project shall include those that could feasibly accomplish most of the basic objectives of the project and could avoid or substantially lessen one or more of the significant effects. The EIR should briefly describe the rationale for selecting the alternatives to be discussed. The EIR should also identify any alternatives that were considered by the lead agency but were rejected as infeasible during the scoping process and briefly explain the reasons underlying the lead agency's determination. Additional information explaining the choice of alternatives may be included in the administrative record. Among the factors that may be used to eliminate alternatives from detailed consideration in an EIR are:(i) failure to meet most of the basic project objectives, (ii) infeasibility, or (iii) inability to avoid significant environmental impacts." Because the Market Street alternative was found to not reduce or eliminate the Project's significant environmental impacts and was found to result in increased environmental impacts in terms of expanding the development footprint through Newhall Creek, requiring additional grading, and connecting a major roadway to a residential street, this alternative was rejected from further consideration. COMMENT 12.6 As a bureaucratic diversion intended to dilute any opposition to the Dockweiler Project and its eventual intended tie to the Lyons Crossing, purported "alternatives" to the Lyons Avenue Crossing have been referenced in the form of crossings at 13a' Street and Market Street, neither of which provides any support for the Dockweiler Project and its intended resulting flow of thousands of additional vehicles through the Placerita Specific Standards District. RESPONSE TO COMMENT 12.6 With respect to the commenter's opinion regarding the alternatives presented in the DEIR, as stated in Section 6.1 Introduction, page 6.1-1, pursuant to CEQA Guidelines Section 15126.6(a), an EIR is required to describe a range of reasonable alternatives to the project, or to the location of the project, which would feasibly attain most of the basic objectives of the project but would avoid or substantially lessen any of the significant effects of the project, and evaluate the comparative merits of the alternatives. The commenter's opinion has been noted for the record and will be forwarded to the decision -makers for their consideration. No further response with regards to the DEIR is warranted. Lyons Avenue/Dockweiler Drive Extension Project Final EIR 3. Responses to Comments State Clearinghouse No. 2013082016 Page 3-36 City of Santa Clarita February 2018 COMMENT 12.7 Aside from the major intended increase in traffic volume on Dockweiler, the proposed construction on Dockweiler itself will not meet current highway safety standards, as the gradient of 11.5% (based on the City's own analyses) far exceeds the legally allowable grade of less than 6%, immediately disqualifying Doweiler [sic] from available federal and state funding, causing the City to have to bear the sole cost and expense of millions of dollars to construct a substandard cross-town highway. In short, the Dockweiler Project effectively drops straight down a cliff to reach the river grade before crossing the railroad. RESPONSE TO COMMENT 12.7 The commenter incorrectly states that the Proposed Project will not meet safety standards based on the grading. As concluded in the DEIR, the Proposed Project would be built to the adopted roadway standards for Secondary Highway of the City's Circulation Element. The extent of grading and contour of the proposed roadway extension is illustrated in Figure 2-14, Proposed Dockweiler Drive Alignment and Grading Plan Profile (See page 2-22 of the DEIR). As shown in Figure 2-14, the maximum gradient of the Dockweiler Drive extension is 4.67%. The commenter's assertion that the proposed alignment has a gradient of 11.5% is incorrect and not supported by the information presented in the DEIR. The commenter's opinion has been noted for the record and will be forwarded to the decision -makers for their consideration. COMMENT 12.8 Even more egregious is that the Dockweiler Project which would funnel these thousands of additional vehicles would be on a roadway that would be only 10-15 feet from some of the existing structures in an established multiple family and condominium community.2 RESPONSE TO COMMENT 12.8 The commenter is referring to the multi -family residential community located along Dockweiler Drive to the southeast of the Proposed Project, which lies outside of the limits of the Proposed Project. Furthermore, the construction of Tract No. 32365 in which the commenter is referring to included the construction of Dockweiler Drive as a major roadway with a 73 foot right-of-way and was designed as a major roadway. While Dockweiler Drive currently terminates at the western limits of Tract No. 32365, it was designed to continue westward as a major roadway consistent with the City's Circulation Element. The portion of Dockweiler that extends from the Master's University to the current terminus of Dockweiler was evaluated under a separate EIR (The Master's College Master Plan DEIR, dated July 2008, and Final EIR, dated October 2008. SCH No. 2004021002), and was approved in 2009. The 2 If Dockweiler is constructed with two lanes of traffic in each direction, it would be extremely close to the existing condominiums at the top of the hill, even though former Community Development Director Paul Brotzman deceptively pledged to those residents that the planned expansion would never be built. Lyons Avenue/Dockweiler Drive Extension Project Final EIR 3. Responses to Comments State Clearinghouse No. 2013082016 Page 3-37 City of Santa Clarita February 2018 commenter's concerns have been noted for the record and will be forwarded to the decision -makers for their consideration. No further environmental analysis is warranted. COMMENT 12.9 An even further defect on the list of defective analyses is the fact that the proposed Lyons Crossing will expose the railroad tracks to erosion and flood damage, as the constriction of the water course by the proposed Lyons Crossing wold [sic] raise the water level under high water storm flows that overtop the elevation of the railroad .3 Placerita Canyon is already susceptible to poor runoff creating flooding on 12a' Street near Placeritos, 13a' Street, and other areas. Such constriction of water flow in the water course will exacerbate the already -existing water flow, flooding, and drainage issues. RESPONSE TO COMMENT 12.9 As discussed in detail in Section 4.6 Hydrology and Water Quality, a post -Project hydraulic model was analyzed to determine the impacts of inundation and flooding (See Hydraulic and Scour Analysis Newhall Creek at Proposed Dockweiler Road Bridge, Newhall, California, prepared by Rivertech, Inc., dated February 2015 ("Hydraulic Report"), (See Appendix G of the DEIR). The hydrology and scour analysis concluded that the Proposed bridge spanning the banks of Newhall Creek would accommodate the Capital Flood, i.e., no overtopping of the road, and will not create any flood hazard for the adjacent railroad and proposed street improvements. The bridge conveys both the 50-year bum/bulk and FIS 100-year flood flows with more than 2 feet of freeboard. Therefore, the construction of the bridge would not be detrimental to adjacent upstream or downstream properties (See also page 4.6-14 of the DEIR). Additionally, improvements to Newhall Creek would be designed in accordance with current regulatory and State permitting agencies. As concluded in the DEIR, impacts associated with flooding would be less than significant and no further analysis of this issue is required. COMMENT 12.10 Yet another unexplored issue relating to any expansion of Dockweiler is MWD's announced intention to expand its services with its planned 20 foot in diameter parallel feed pipe through the Dockweiler alignment. 3 Mike Hennaway [sic] of City of Santa Clarita stated in a December 14, 2009 email to Craig Kwasviewski, Senior Hydrologist/ Project Engineer with HMK Engineering, that "...the profile of the (proposed Lyons) bridge ... is below the Water Surface Elevation ("WSE') for both a 100 year clear flow and a 50 year burned - and -bulked flow, " which means that the bridge would be beneath the level of flood waters in Newhall Creek, and in the event of a heavy rainstorm, the Placerita Canyon community of 450+ homes would be cut off from evacuation and emergency support services by floodwaters cresting over the bridge. The overflows would also inundate the Downtown Newhall area, and the section in front of the new Newhall Library would become a lake due to the built-up roadway required to be raised to meet the top of the tracks for an at -grade Crossing at Lyons. Lyons Avenue/Dockweiler Drive Extension Project Final EIR 3. Responses to Comments State Clearinghouse No. 2013082016 Page 3-38 City of Santa Clarita February 2018 RESPONSE TO COMMENT 12.10 The Metropolitan Water District of Southern California ("Metropolitan") is a commenting agency pursuant to CEQA. Metropolitan submitted a comment letter on the DEIR, dated October 2, 2017 and included herein as Comment Letter No. 8, stating that they own and operate facilities adjacent to but not within the limits of the Proposed Project. Metropolitan's Foothill Feeder, which is an approximate 16- foot, 9-inch inside -diameter pipeline within fee property rights -of -way, is located north of the Proposed Project (Refer to Comment Letter No. 8, Enclosure 1 Location Map of Metropolitan's Foothill Feeder within Project Limits). As specified in Metropolitan's comment letter, design plans for the Proposed Project shall be compatible with Metropolitan's facilities and easements and consistent with Metropolitan's "Guidelines for Development in the Area of Facilities, Fee Properties, and/or Easement of the Metropolitan Water District of Southern California" (Refer to Enclosure 2 of Commenter Letter No. 8). Design plans associated with this project shall be submitted to Metropolitan's Substructures team for approval. As such, no further analysis is required. COMMENT 12.11 Simply, the Lyons Crossing Project does not and cannot exist in the abstract without also fully considering and evaluating of the corresponding impacts of the proposed Dockweiler Project, because they are completely integrated in their intended purpose and use: piecemealing of contemplated Projects to prevent their full analyses and evaluation in their total context is a direct violation of the fundamental requirements of CEQA. The City has failed to comply with CEQA in not completely combining the environmental analyses of Lyons Crossing Project along with the Dockweiler Project. There can be no viable (or legal) alternative Crossing that can be proposed unless and until the full context of the Dockweiler Project is included in the environmental review. RESPONSE TO COMMENT 12.11 The claim that the EIR fails to evaluate the Proposed Project in conjunction with the previously proposed Lyons Avenue At -Grade Crossing Project is incorrect. With respect to the commenter's understanding of the Lyons Avenue At -Grade Crossing Project, see Response to Comment 12.1. COMMENT 12.12 The lesser of evils ---albeit still legally defective in the present context would be the Market Street Alternative, as it would be a better solution to address the access and circulation issues requiring a crossing. That Crossing already exists and could be expanded, and Market Street has the advantage of having access from other parts of Railroad Street prior to the crossing at Railroad/Newhall/Main St. (Pine and Arch St.) The 13th Street alternative will never receive PLC approval. Lyons Avenue/Dockweiler Drive Extension Project Final EIR 3. Responses to Comments State Clearinghouse No. 2013082016 Page 3-39 City of Santa Clarita February 2018 RESPONSE TO COMMENT 12.12 As disclosed in the DEIR in Section 6.1, the Market Street Alternative was evaluated and rejected from further consideration due to the physical constraints associated with grading, as well as the Alternative's incompatibility with respect to public safety and local residential street standards (See Section 6.1, page 6.1-2 of the DEIR). See also Response to Comment 12.38, below, and Section 2. Additions and Corrections, Market Street Alignment Additional Analysis. The commenter's opinion regarding the Market Street and 13th Street alternatives has been noted for the record and will be forwarded to the decision makers for their consideration. No further response is required. COMMENT 12.13 In addition to its objections stated herein, PCPOA restates its previously asserted objections to the proposed Lyons Crossing Project, as follows: Topic 1: Aesthetics There will be significant impact [sic] to the scenic vistas and it will make significant impact [sic] to the rural equestrian nature of the area. An at -grade crossing will mean raising the road bed five to six feet. This will impede the walkability in the section of Downtown Newhall currently undergoing redevelopment, and will virtually bury the historic jailhouse located almost adjacent to the proposed Crossing. The proposed Project will create light, noise and visual blight in a Special Standards District in which these uses are restricted. RESPONSE TO COMMENT 12.13 A detailed analysis of the Proposed Project's impacts to aesthetics including scenic vistas and visual character is provided in Section 4.1 Aesthetics of the DEIR (See pages 4.1-9 through 4.1-14). With respect to the commenter's concerns regarding the Proposed Project's impact to scenic vistas and visual character, no buildings or development is proposed on the Project Site that would block existing views or substantially degrade the visual character of the Old Town Newhall community. Construction impacts would be reduced to less than significant levels with the implementation of mitigation measure 4.1-1, which would require the contractor to erect screening materials such as fences or other closures to effectively block the line of sight of unsightly stockpiles of construction debris and soil, and construction equipment from neighboring residential properties. Mitigation measure 4.1-2 would ensure that the roadway median and contoured slopes along the roadway alignment would be attractively landscaped and maintained in accordance with landscape plans to the satisfaction of the City Planning Department. With the incorporation of mitigation measures 4.1-1 and 4.1-2, impacts upon aesthetics, including scenic vistas and visual character would be less than significant. With respect to access, Dockweiler Drive would include sidewalks for pedestrian use and Class II bike lanes on each side. Class II bike routes would provide a striped lane for one-way bike travel and would be marked with signs and pavement striping. Potential Bike Lane connectors would be proposed from Lyons Avenue/Dockweiler Drive Extension Project Final EIR 3. Responses to Comments State Clearinghouse No. 2013082016 Page 3-40 City of Santa Clarita February 2018 Dockweiler Drive to connect to the Proposed Class I Bike Path along Railroad Avenue and the existing Class II Bike Path along Railroad Avenue. With respect to light, as disclosed in the DEIR, the Project would be expected to slightly increase ambient lighting in the area, but compliance with the design standards and requirements established in the Santa Clarita Municipal Code Section 17.050 would mitigate lighting impacts to a less than significant level. With respect to impacts upon the historic jailhouse, grading for the roadway extension of Lyons Avenue to Dockweiler Drive would not adversely impact the Old Newhall Jail, located at 24522 Spruce Street. This historic property is identified in Figure 4.4-1 in Section 4.4 Cultural Resources. The Proposed Project would not alter or affect the grade within the immediate vicinity of the Old Newhall Jail. Cross section illustrations of the grading plan profile at the Lyons Avenue railroad at -grade crossing and Newhall Creek overcrossing are shown in Figure 2-15, Proposed Grading Plan Profile and Cross Section of the Railroad Crossing at Lyons Avenue (See page 2-23 of the DEIR). Additionally, Figure 2.16 depicts the proposed grading plan profile and cross sections of the railroad crossing at Lyons Avenue and Railroad Avenue, as well as the intersection and at the Newhall Creek overcrossing (See page 2-25 of the DEIR). With respect to noise, as disclosed in Section 4.8 Noise, of the DEIR, the estimated construction noise levels impacting sensitive receptors are expected to exceed the City's daytime noise standards for residential uses (See Section 4.8, Table 4.8-3, page 4.8-9). The construction noise levels would therefore constitute a significant impact. During operation of the Proposed Project, the anticipated noise levels at all off -site receptor locations would be within the "normally acceptable" range of noise for residential areas. The relocation of the existing railroad crossing signal at 13th Street and Railroad Avenue (approximately 1,150 feet south to the Lyons Avenue and Railroad Avenue crossing) would not result in a noticeable change to the ambient noise levels during train events. Therefore, the Proposed Project's noise impacts would be less than significant. In summary, with the exception of temporary construction noise, which would be a significant and unavoidable impact (as discussed above and disclosed in the DEIR), the Proposed Project would be in compliance with the standards identified in the PCSSD. The commenter provides no substantial evidence, pursuant to Public Resources Code Section 21080(e) (2), to support their assertion that the Proposed project would result in significant impacts, not already disclosed in the DEIR, with respect to scenic vistas and visual character. Therefore, no further analysis is required with respect to CEQA. COMMENT 12.14 Topic 2: Agricultural Resources The proposed at -grade Crossing will alter an area near equestrian facilities. Tractors and other farm equipment are common on local streets; they also use the crossing presently at 13th Street. Placerita Canyon is a Rural Equestrian Community, specifically so [sic] designated as a Special Standards District in Santa Clarita's UDC. Lyons Avenue/Dockweiler Drive Extension Project Final EIR 3. Responses to Comments State Clearinghouse No. 2013082016 Page 3-41 City of Santa Clarita February 2018 RESPONSE TO COMMENT 12.14 As analyzed in Section 4.7, Table 4.7-3, page 4.7-18, of the DEIR, the Proposed Project is in substantial compliance with the standards identified in the PCSSD. The proposed connection of Lyons Avenue to Dockweiler Drive would not conflict with, alter or remove any equestrian facilities or trails. To the contrary the Proposed Project would improve access in the PCSSD, as the proposed alignment of Dockweiler Drive would include Class II Bike Routes and pedestrian walkways. COMMENT 12.15 Topic 3: Air quality The Santa Clarita commercial center area is already out of compliance with Federal and State clean air standards, and there will be at least three additional elements that have to be considered: more trains, more traffic, and longer waits for each vehicle to make the crossing, which will create even more air pollution in an area that is already suffering. RESPONSE TO COMMENT 12.15 With respect to the commenter's general concerns regarding impacts to air pollution and clean air standards, see Section 4.2 Air Quality, of the DEIR. As noted in Section 4.2, the DEIR properly disclosed that the Santa Clarita Valley is in non -attainment with the California and Federal Air Quality Standards for ozone (03) and PMIO, and PM2.5. The commenter's assertion that the Proposed Project would result in more trains, more traffic and longer waits for vehicles to cross at -grade crossings is incorrect and unsubstantiated. The Proposed Project would add an additional east west connector to facilitate traffic between the Old Town Newhall community and the neighborhoods to the east. The Proposed Project does not include any commercial or residential land uses that would generate additional traffic. Additionally, the proposed alignment would be used by motorists to reduce travel time or otherwise avoid congested intersections in the local area. As an additional alternative route, the Proposed Project is expected to result in fewer VMT's as the proposed connection between Dockweiler Drive and Railroad Avenue would shorten the distance traveled as compared to existing traffic patterns. Therefore, as concluded in Section 4.2, Air Quality, the Proposed Project's impacts upon regional air quality would be less than significant. COMMENT 12.16 Under the Global Warming Solutions Act of 2006, California emissions must be reduced to 1990 levels by the year 2020. The heavier volume of traffic in the heart of the commercial and governmental center of Santa Clarita, combined with longer wait times, will result in more emissions not less in an already non - attainment area. Lyons Avenue/Dockweiler Drive Extension Project Final EIR 3. Responses to Comments State Clearinghouse No. 2013082016 Page 3-42 City of Santa Clarita February 2018 RESPONSE TO COMMENT 12.16 The commenter's assertion that the Proposed Project would result in longer wait times and generate more air quality emissions is not substantiated. To the contrary, as noted in Section 4.9, Transportation and Traffic, based on an evaluation of the Proposed Project's impact on are roadways, the Proposed Project is anticipated to reduce vehicle delays at nine of the 16 study intersections analyzed during the A.M. and P.M. peak hours for the 2019 buildout year scenario and at 12 of the 16 intersections during the A.M. and P.M. peak hours for the 2035 buildout year scenario. Overall, the Proposed Project would reduce traffic congestion on local roadways and would reduce travel time and the amount of time vehicles idle at intersections. Thus, contrary to the commenter's assertion, the Proposed Project would not result in heavier traffic with an increase in emissions. Nonetheless, with respect to the AB 32, Global Warming Solutions Act of 2006, the City of Santa Clarita adopted a Climate Action Plan (CAP), which provides policies and identifies actions intended to reduce GHG emissions within the City and assist in the fight against Climate Change. Overall the goal of the CAP is to reduce Santa Clarita's community -wide GHG emissions below the 2005 baseline emissions by 2020. Implementation of the strategies identified in the CAP would also exceed the City's goal to reduce 2020 GHG emissions to a level below the 2005 GHG emissions baseline by 4 percent. The commenter's concerns have been noted for the record and will be forwarded to the decision makers for their consideration. No further analysis is required. COMMENT 12.17 Topic 4: Biological Resources The proposed Lyons Avenue at -grade Crossing will adversely affect Newhall Creek, an identified "blue line stream" under Fish and Game jurisdiction, and also likely under federal Fish & Wildlife jurisdiction since Newhall Creek would be considered to be "waters of the United States." To accommodate this Crossing and its required elevation change to be at -grade, Newhall Creek would need to be bridged and channeled. Newhall Creek is a natural highway for wildlife, both large and small, including deer, cougars, bobcats, coyotes, skunks, opossums, rabbits, mice, squirrels, snakes, lizards, raptors, owls, turkey vultures, road runners and other species. RESPONSE TO COMMENT 12.17 With respect to the Proposed Project's impacts to wildlife movement through Newhall Creek, as discussed further in Section 4.3 Biological Resources, of the DEIR, four 25-foot wide and 8-foot deep openings in a concrete box bridge with 80-foot wide soft base and 2:1 protected side slopes is proposed where the proposed roadway extension crosses Newhall Creek. As designed, this bridge would not result in any barrier to wildlife movement and would serve to protect Newhall Creek as a functioning wildlife movement corridor. Impacts upon wildlife were analyzed in the Biological Resources Assessment (contained in Appendix D to the DEIR and summarized in Section 4.3, Biological Resources). As noted in the DEIR, the project as proposed would not result in significant impacts to wildlife movement. With Lyons Avenue/Dockweiler Drive Extension Project Final EIR 3. Responses to Comments State Clearinghouse No. 2013082016 Page 3-43 City of Santa Clarita February 2018 the incorporation of mitigation measures 4.3-1 through 4.3-7, impacts upon biological resources, including vegetation and wildlife resources would be less than significant. No further analysis is warranted. COMMENT 12.18 The local oak trees are also highly protected under Santa Clarita's ordinances; changing the water flow will be a threat to many of these cherished denizens, which has to be evaluated. RESPONSE TO COMMENT 12.18 As disclosed in the DEIR, Section 4.3 Biological Resources, two coast live oaks were the only special - status plants observed during the field investigation. The two oak trees that occur within the project limits would be required to be removed for project construction. A permit is required for the encroachment into the Protected Zone. Native oak trees are protected under City of Santa Clarita Oak Tree Ordinance (Ordinance No. 89-10, passed by the City Council on April 25, 1989) and the City's Oak Tree Preservation and Protection Guidelines (adopted September 11, 1990). Replacement oak trees would be planted in the number necessary to comply with the requirements stipulated in the Oak Tree Permit issued by the City. With approval of the required oak tree permits, and implementation of Mitigation Measure 4.3-7, impacts upon the loss or pruning of any oak tree would be reduced to less than significant levels. No further analysis is required. COMMENT 12.19 There are many City -built hiking and equestrian trails in the area. Changes to the creek bed will affect these crossings and uses. RESPONSE TO COMMENT 12.19 The commenter's assertion that changes to the creek bed will affect City -built hiking and equestrian trails in the area is unsubstantiated. Neither the temporary construction impacts within the footprint of the Newhall Creek, nor any of the grading impacts associated with the proposed alignment of Lyons Avenue or Dockweiler Drive will result in direct impacts upon existing City built hiking or equestrian trails. To the contrary, the Proposed Project would improve access in the project vicinity. Dockweiler Drive would include a Class II Bike Route and sidewalks. The Proposed Project will be designed in accordance with the appropriate design features and standards required for secondary highways and railroad crossings. The bridge crossing above Newhall Creek would not impede wildlife movement or equine access within the creek bed. Further all physical improvements to the proposed roadways, pedestrian walkways and hiking trails to be constructed as part of the Proposed Project would be subject to the site plan review requirements of the City of Santa Clarita. Lyons Avenue/Dockweiler Drive Extension Project Final EIR 3. Responses to Comments State Clearinghouse No. 2013082016 Page 3-44 City of Santa Clarita February 2018 COMMENT 12.20 The proposed at -grade Lyons Crossing will affect the ultimate flow of the Santa Clara River, of which Newhall Creek is a tributary. Full current hydrology studies must be conducted to determine the capacity status of all drains, channels and related facilities. RESPONSE TO COMMENT 12.20 Section 4.6 Hydrology and Water Quality includes a thorough analysis of the Proposed Project's impacts with respect to hydrology and water quality. A post -Project hydraulic model was analyzed to determine the impacts of inundation and flooding (See Hydraulic and Scour Analysis Newhall Creek at Proposed Dockweiler Road Bridge, Newhall, California, prepared by Rivertech, Inc., dated February 2015, which is provided in Appendix G of the DEIR). The hydrology and scour analysis concluded that the Proposed bridge spanning the banks of Newhall Creek would accommodate the Capital Flood, i.e., no overtopping of the road, and will not create any flood hazard for the adjacent railroad and proposed street improvements. The bridge conveys both the 50-year bum/bulk and FIS 100-year flood flows with more than 2 feet of freeboard. Therefore, the construction of the bridge would not be detrimental to adjacent upstream or downstream properties (See page 4.6-14 of the DEIR). Additionally, improvement to Newhall Creek would be designed in accordance with current regulatory and State permitting agencies. As concluded in the DEIR, impacts associated with flooding would be less than significant, and no further analysis of this issue is required. COMMENT 12.21 Topic 5: Cultural Resources The historic Old Jail building in Santa Clarita is a cultural icon that will be threatened with the ramping up of Lyons Avenue to make it an at -grade railroad crossing. RESPONSE TO COMMENT 12.21 The commenter's assertion that the Old Newhall Jail will be threatened with the ramping of Lyons Avenue is unsubstantiated and incorrect. Grading for the roadway extension of Lyons Avenue to Dockweiler Drive would not adversely impact the Old Newhall Jail, located at 24522 Spruce Street. Cross section illustrations of the grading plan profile at the Lyons Avenue railroad at -grade crossing and Newhall Creek overcrossing are shown in Figure 2-15, Proposed Grading Plan Profile and Cross Section of the Railroad Crossing at Lyons Avenue, Figure 2.16, Proposed Grading Plan Profile and Cross Section of the Railroad Crossing at Railroad Avenue, and Figure 2-17, Lyons Avenue Street Widening — Proposed New Crossing. (See pages 2-23, 2-25 and 2-26 of the DEIR). As shown in these renderings, no grading is proposed outside of the existing right-of-way along Railroad Avenue. The proposed elevation change within the right-of-way will not affect the surface parking lot of the existing Newhall Library building, nor would affect the Old Newhall Jail, which is set back over 195 feet from Railroad Avenue. No further analysis with respect to cultural resources is warranted. Lyons Avenue/Dockweiler Drive Extension Project Final EIR 3. Responses to Comments State Clearinghouse No. 2013082016 Page 3-45 City of Santa Clarita February 2018 COMMENT 12.22 Topic 6: Geology The area of the at -grade crossing is a known seismically active area and subject to liquefaction. RESPONSE TO COMMENT 12.22 As concluded in Section 4.5 Geology of the DEIR, the majority of the Project Site is underlain by bedrock materials that are not susceptible to liquefaction. The alluvial soils present at the site, as depicted in Figure 4.5-2 on page 4.5-4 of the DEIR, are not designated on the State of California Seismic Hazard Zone Map for the Newhall Quadrangle as a zone in which investigation of potentially liquefiable materials is required. The depth to historic high ground water at the Project Site is greater than 50 feet. Based on the preceding factors, the potential for liquefaction and associated seismic settlements and lateral spreading is therefore considered very low. (Refer also to Geologic and Geotechnical Report EIR- Level Review Of Road Alignments For Dockweiler Road and Lyons, prepared by Allan E. Seward Engineering Geology, Inc., dated October 17, 2014, included as Appendix F of the DEIR). No further analysis is required. COMMENT 12.23 Topic 7: Hazards and Hazardous Materials San Fernando Road (now, Railroad Ave.) is approved for the transporting of hazardous materials. The area is slated for industrial development and will result in hazardous materials crossing the railroad tracks at Lyons Avenue. Trains will also be carrying hazardous materials. Heavy vehicle traffic congestion will increase the potentiality of vehicle interference, and thus collisions and spills. RESPONSE TO COMMENT 12.23 As discussed in Section 5.1 Impacts Determined to be Less Than Significant, of the DEIR (See pg. 5.1-2) a significant impact may occur if a project involves the use or disposal of hazardous materials as part of its routine operations, which may have the potential to generate toxic or otherwise hazardous emissions that could adversely affect sensitive receptors. The Proposed Project itself would not require the transport, use, and/or disposal of potentially hazardous materials. The commenter's concern has been noted for the record and will be forwarded to the decision -makers for their considerations. No further analysis with respect to the DEIR is warranted. COMMENT 12.24 Topic 8: Hydrology FEMA studies show that much of Placerita Canyon as well as much of the area affected by the proposed Lyons Avenue at -grade Crossing and extension to Dockweiler to be in a floodway. An EIR is required to Lyons Avenue/Dockweiler Drive Extension Project Final EIR 3. Responses to Comments State Clearinghouse No. 2013082016 Page 3-46 City of Santa Clarita February 2018 analyze and to show how that designation will impact all traffic flow and how roads must be designed to avoid the areas of concern. A FEMA letter sent to the City dated August 9, 2013 confirms the vulnerability of Placerita Canyon to flooding. RESPONSE TO COMMENT 12.24 As disclosed in Section 4.6 Hydrology and Water Quality, the western portion of the roadway extension that crosses Newhall Creek, is located in a "Zone A", as identified in the National Flood Insurance Rate Map for Los Angeles County. Zone "A" indicates a special flood hazard area that is subject to inundation by the 1% annual chance flood (100-year flood) (See also Geologic and Geotechnical Report EIR-Level Review Of Road Alignments For Dockweiler Road and Lyons Avenue, dated October 17, 2014, Appendix F of the DEIR). A post -Project hydraulic model was analyzed to determine the impacts of inundation and flooding (See Hydraulic and Scour Analysis Newhall Creek at Proposed Dockweiler Road Bridge, Newhall, California, prepared by Rivertech, Inc., dated February 2015 ("Hydraulic Report"), which is provided in Appendix G of the DEIR). The hydrology and scour analysis concluded that the proposed bridge spanning the banks of Newhall Creek would accommodate the Capital Flood, i.e., no overtopping of the road, and will not create any flood hazard for the adjacent railroad and proposed street improvements. The bridge conveys both the 50-year bum/bulk and FIS 100-year flood flows with more than 2 feet of freeboard. Therefore, the construction of the bridge would not be detrimental to adjacent upstream or downstream properties (See also page 4.6-14 of the DEIR). Additionally, improvement to Newhall Creek would be designed in accordance with current regulatory and State permitting agencies. As concluded in the DEIR, impacts associated with flooding would be less than significant and no further analysis of this issue is required. COMMENT 12.25 The Crawford, Multari & Clark study (April 10, 2008) indicates "Potentially Significant Impacts" to all aspects of Hydrology and Water Quality. The Lyons Avenue Project may violate water quality standards and waste discharge requirements, affects groundwater supplies, alter the existing drainage pattern through the alteration of the course of a stream, and affect erosion or siltation. Further, the Project may also affect the overall drainage pattern and increase runoff, causing flooding both on and off -site. This is in an area in which the City has previously warned residents in writing to pay particular attention to protecting themselves from the danger of flooding. (October 2012 letter.) RESPONSE TO COMMENT 12.25 The commenter is referencing an outdated study that was conducted for the prior Lyons Avenue At -Grade Rail Crossing Project DEIR, which was prepared in 2010. Refer also to Response to Comment 12.1, above. The Proposed Project's impacts to hydrology, surface runoff and water quality were thoroughly evaluated and disclosed in Section 4.6 Hydrology and Water Quality, of the DEIR. As noted in the EIR, the Proposed Project would be required to prepare and implement Storm Water Pollution Prevention Plan ("SWPPP") prior to earthwork activities that will use best management practices and erosion control measures to prevent pollution in stormwater discharge. All Project construction activities would comply Lyons Avenue/Dockweiler Drive Extension Project Final EIR 3. Responses to Comments State Clearinghouse No. 2013082016 Page 3-47 City of Santa Clarita February 2018 with the City's grading permit regulations, which require the implementation of grading and dust control measures, including a wet weather erosion control plan if construction occurs during rainy season, as well as inspections to ensure that sedimentation and erosion is minimized. Therefore, through compliance with National Pollutant Discharge Elimination System ("NPDES") requirements and City grading regulations, the Project's construction impacts related to water quality would not violate any water quality standards or waste discharge requirements or otherwise substantially degrade water quality. Additionally, in accordance with NPDES requirements, the Project Applicant would be required to have a Project -specific Standard Urban Stormwater Mitigation Plan ("SUSMP") in place during the operational life of the Project to address the management of runoff from the proposed roadway extension. The SUSMP would include site design, source control, low -impact development, and best management practices. Therefore, during the Project's construction and operation implementation of regulatory compliance would reduce water quality impacts to less than significant. With respect to potential for flooding, please refer to Response to Comment 12.24, above. No further analysis is required. COMMENT 12.26 Topic 9: Land Use and Planning Previously applied for/approved projects affecting this proposed Project include Master's College and Placerita Baptist Church expansions, and expansions for Our Lady of Perpetual Help Catholic Church. The impact of the Compass Project, a high -density transit oriented development, must be weighed along with traffic from Dockweiler and Valle del Oro that previously used Newhall Avenue to access Lyons, because much of that traffic will be diverted this proposed at -grade Crossing at Lyons. RESPONSE TO COMMENT 12.26 As further discussed in Section 4.9 Transportation and Traffic, the Proposed Project's future year traffic volumes incorporated the growth assumptions pursuant to the Santa Clarita Valley Consolidated Traffic Model ("SCVCTM"). The related projects identified by the commenter, along with other related development anticipated to occur as a result of the General Plan Buildout were incorporated into the SCVCTM and account for expected growth. As such, the commenter's concerns have been addressed in the DEIR and no further analysis is required. COMMENT 12.27 The Lyons at -grade Crossing will facilitate new development which will conflict with Placerita Canyon's Special Standards District which was promised to residents and written into the UDC to maintain the rural equestrian nature of Placerita Canyon. The Special Standards District has no sidewalks, and no curbs or gutters, and special lighting must be designed to be compatible with the area. Such potential development must also be anticipated and evaluated. Lyons Avenue/Dockweiler Drive Extension Project Final EIR 3. Responses to Comments State Clearinghouse No. 2013082016 Page 3-48 City of Santa Clarita February 2018 RESPONSE TO COMMENT 12.27 The commenter raises concerns that the Proposed Project would conflict with the standards established by the PCSSD. As disclosed in the EIR, the Proposed Project is located in the PCSSD and is part of the North Newhall Area ("NNA"). As analyzed in Section 4.7, Table 4.7-3, on page 4.7-18 of the DEIR, the Proposed Project is in substantial compliance with the standards identified in the PCSSD. The commenter does not specify how the Proposed Project would be inconsistent with the PCSSD. Therefore, no further analysis with respect to the DEIR is warranted. COMMENT 12.28 Topic 10: Mineral Resources The area served by the proposed at -grade Crossing is adjacent to an oil production area, whose trucks will traverse the Crossing. RESPONSE TO COMMENT 12.28 As discussed in Section 5.1 Impacts Determined to be Less Than Significant, of the DEIR (See pg. 5.1-2), a significant impact may occur if a project involves the use or disposal of hazardous materials as part of its routine operations, which may have the potential to generate toxic or otherwise hazardous emissions that could adversely affect sensitive receptors. The Proposed Project itself would not require the transport, use, and/or disposal of potentially hazardous materials. Additionally, the Project Site is not located in an area of potential petroleum resources. The commenter's concern has been noted for the record and will be forwarded to the decision -makers for their considerations. No further analysis with respect to the DEIR is warranted. COMMENT 12.29 Topic 11: Noise The design and construction of the proposed at -grade Lyons Crossing, including the lowering of some of the ridgelines called for in OVOV, would allow more noise from trains and traffic to penetrate the entire area. The Crossing remove [sic] or reduce some of the existing physical barriers to noise. The area would clearly become a traffic "hub" if the Lyons Crossing were approved, as it would connect with other major roads throughout the City. The Lyons Avenue at -grade Crossing would carry the highest crossing traffic volume in the Santa Clarita Valley With the possibility of five at -grade Crossings (Newhall Ave., Market St., Lyons Ave., 13th St., and Circle J) in a two-mile stretch, train whistles will sound for an extended period of time every time a train passes through town at all hours of the day and night which will be a significant disturbance to broad swaths of the community. Lyons Avenue/Dockweiler Drive Extension Project Final EIR 3. Responses to Comments State Clearinghouse No. 2013082016 Page 3-49 City of Santa Clarita February 2018 RESPONSE TO COMMENT 12.29 The commenter's statement that the Lyons Avenue At -Grade Crossing would carry the highest crossing traffic volume in the Santa Clarita Valley is unsubstantiated and incorrect. As shown in Table 4.9-8 Railroad Crossing Analysis — Project Year 2019 Conditions, Lyons Avenue would experience 8,060 railroad vehicle crossings, while Newhall Avenue would experience 44,790 railroad vehicle crossings in 2019. Thus under the 2019 analysis year, Lyons Avenue would experience approximately 18 percent of the total volume of crossings experienced at Newhall Avenue. For the Future Year 2035 Conditions, as shown in Table 4.9-10, Lyons Avenue would experience 28,870 railroad vehicle crossings, as compared to 47,100 railroad vehicle crossings that are projected to occur at Newhall Avenue. Thus under the 2035 analysis year, Lyons Avenue would experience approximately 61 percent of the total volume of crossings experienced at Newhall Avenue. Additionally, the commenter is incorrect in their assertion that the Proposed Project would result in the operation of both a crossing at Lyons Avenue and Railroad Avenue and a crossing at 13a' Street and Railroad Avenue. To clarify, the Proposed Project includes the addition of a new at -grade crossing at Lyons Avenue and Railroad Avenue and the closure of the crossing at 13a' Street and Railroad Avenue. With respect to the Project's impacts to noise, as discussed in detail in Section 4.8 Noise of the DEIR, future noise levels on the new roadway segment from Lyons Avenue to Valle del Oro are expected to be 63.3 dBA (CNEL) within 50 feet of the centerline of the roadway. The resulting noise levels at the three identified sensitive receptors would be below 52.9 dBA. Thus, the anticipated with project noise levels at all off -site receptor locations would be within the "normally acceptable" range of noise for residential areas. Therefore, the Proposed Project's noise impacts would be less than significant. As evaluated in the DEIR, the closure of the existing at -grade railroad crossing at 13a' Street would reduce the railroad warning signal bell levels in the vicinity of 13a' Street and Railroad Avenue as the railroad crossing warning signal devices would be removed at this location and installed at a new at -grade crossing at Lyons Avenue and Railroad Avenue. The relocation of the existing railroad crossing signal at 13a' Street and Railroad Avenue approximately 1,150 feet south to the Lyons Avenue and Railroad Avenue crossing would not result in a noticeable change to the ambient noise levels during train events. Noise impacts from at -grade warning signals would be less than significant. The commenter's opinions and concerns have been noted for the record and will be forwarded to the decision makers for their consideration. No further analysis is required. COMMENT 12.30 Topic 12: Population and Housing OVOV has proposed to induce substantial population growth both directly and indirectly, all of which will be using the at -grade Lyons Crossing. Directly, development of the property adjacent to the Lyons Crossing will increase dwelling units by 150% (plus the approved Compass Project), may add 500,000- 700,000 square feet of commercial industrial space, may allow for a hotel/spa, will allow 40,000-50,000 Lyons Avenue/Dockweiler Drive Extension Project Final EIR 3. Responses to Comments State Clearinghouse No. 2013082016 Page 3-50 City of Santa Clarita February 2018 square feet of new local retail, and add (a proposed) additional elementary school. Indirectly, the resulting growth will create a new traffic hub that will adversely affect a long -existing rural equestrian neighborhood, and will displace some of its existing homes and local businesses. RESPONSE TO COMMENT 12.30 The commenter does not raise a specific concern related to the environmental analysis or methodology as presented in the DEIR. The Proposed Project involves the buildout of a proposed roadway alignment that was identified within the City's Circulation Element of the General Plan and assumes for projected growth to occur consistent with the growth projections of the General Plan Buildout. No residential, commercial, or industrial land uses are proposed. The potential displacement of existing properties is noted in the Project Description Section of the DEIR under the heading Property Acquisition and/or Easements. (See Table 2-1, Potential Property Acquisition and/or Easements and Figure 2-18, Dockweiler Drive Study Area — Adjacent Properties Map). COMMENT 12.31 Topic 13: Public Services The proposed Lyons Crossing would be a traffic hub which could impede response time for fire, sheriff, and other emergency vehicles. The resulting proposed new development would further increase demand and need for those services. RESPONSE TO COMMENT 12.31 As discussed in Section 5.1 Impacts Determined to be Less Than Significant, page 5.1-3, subheading Fire and Police Protection, of the DEIR, the Proposed Project would not directly increase the demands for fire and police protection as the Project does not include any new housing units or commercial uses. Emergency access to the Placerita Canyon community would be facilitated through the Proposed Project's alignment, which is consistent with the City's adopted Circulation Element. The Proposed Project's alignment would be an improvement to the current access route into the Placerita Canyon community via 13th Street. The closure of the 13th Street at -grade crossing is a proposed safety feature aimed at reducing potential conflicts between pedestrians, vehicles and trains. Furthermore, as noted in Comment Letters No. 4 and 5, the Los Angeles County Fire Department and the Los Angeles County Sheriff's Department reviewed and commented on the DEIR. (See Comment Letters No. 4 and 5, above). As noted in Comment Letter No. 4, the Los Angeles County Fire Department requests all proposals that include traffic calming measures be submitted for their review. The Proposed Project would comply with this request. As noted in Comment Letter No. 5, the Los Angeles County Sheriffs Station noted that the Proposed Project is intended to relieve existing and projected traffic congestion by reconfiguring, abandoning, and/or extending certain street segments, relocating an existing at -grade railroad crossing, and creating dedicated pedestrian and bicycle lanes. The Station generally supports these types of public improvements because they typically result in an overall positive impact upon law enforcement patrol operations, emergency access, and response times. (See Comment Letter No. 5, above). As such, the Lyons Avenue/Dockweiler Drive Extension Project Final EIR 3. Responses to Comments State Clearinghouse No. 2013082016 Page 3-51 City of Santa Clarita February 2018 Proposed Project's impact upon fire and police services would be less than significant, and no further analysis is warranted. COMMENT 12.32 Topic 14: Recreation Placerita Canyon is a rural equestrian area with a large active facility hosting frequent regional horse shows. A second equestrian facility is planned, increasing the amount of horse trailer traffic across the railroad crossing. Santa Clarita's trail system has many existing paths in Placerita Canyon and more planned. These accommodate hikers, bicyclists, and equestrians, all of whom would access the area by the at -grade railroad Crossing. RESPONSE TO COMMENT 12.32 This comment is noted for the record and will be forwarded to the decision makers for their consideration. COMMENT 12.33 Topic 15: Transportation A second rail line has been constructed in the area, confirming the demand for additional rail traffic. Additional train traffic can be expected from the proposed feeder lines for ExpressRail. The effect of the High Speed Rail Project on existing facilities is yet unknown but must be anticipated. RESPONSE TO COMMENT 12.33 The addition and timeline of the proposed High Speed Rail is speculative and immaterial with respect to addressing the Proposed Project's impacts. The Los Angeles County Metropolitan Transportation Authority (Metro) and the Southern California Regional Rail Authority (SCRRA) have reviewed the DEIR and provided comments addressing the operations of the existing railroad (see Comment Letters No. 7 and 10, respectively). As noted by Metro, rail service currently operates in both directions and trains may operate in and out of revenue service, 24 hours a day, seven days a week, and in the R-O-W adjacent to the Proposed Project. The effects of the High Speed Rail Project are evaluated under a separate EIR authored by the California High Speed Rail Authority. In 2001, the Authority, in cooperation with the Federal Railroad Administration (FRA), started a tiered environmental review process for the statewide high-speed rail system per requirements of the California Environmental Quality Act (CEQA) and the National Environmental Policy Act (NEPA). The 2005 first -tier California High - Speed Rail Program Final Environmental Impact Report/Environmental Impact Statement (Statewide Program EIR/EIS) described the program alignment, which included a corridor between Palmdale and Los Angeles. The environmental document for the Palmdale to Burbank Project Section has not yet been published. However, based on fact sheet for the Palmdale to Burbank Project Section, three alignments along the approximately 40-mile corridor are being considered, known as State Route 14, El, and E2. None of these routes pass through the City of Santa Clarita and as such it is not anticipated that the High Lyons Avenue/Dockweiler Drive Extension Project Final EIR 3. Responses to Comments State Clearinghouse No. 2013082016 Page 3-52 City of Santa Clarita February 2018 Speed Rail Project would have any impacts within the Newhall Area. As such, no further analysis is warranted. COMMENT 12.34 The Lyons Project analysis must fully account for proximity to the Newhall Metrolink Station. Every Metrolink train will bring traffic to a halt whether or not it stops at the station, and the frequency will be greater during peak hour vehicle traffic. When a train is stopped at the Newhall Metrolink Station, the arms will be down for an extended time. RESPONSE TO COMMENT 12.34 The Proposed Project would include a new at -grade crossing at the proposed extension of Lyons Avenue from Railroad Avenue. The Proposed Project would include the closure of the existing at -grade crossing at 13th Street and Railroad Avenue. The new crossing would be located approximately 0.25 mile north of the existing at -grade crossing located at Market Street. Similar to existing conditions, the Proposed Project would not provide access between Dockweiler Drive to Market Street. Therefore, in the event that railroad gates are in a down position at the new crossing at Lyons Avenue, when a train is stopped at the Metrolink station to the south, the traffic on Market Street would remain unaffected by the new at -grade crossing. Under the Alternative 2 Project, the 13t'' Street at -grade crossing would remain and no at -grade crossing would occur at Lyons Avenue and Railroad Avenue, when a train is stopped at the Metrolink station to the south. As such, future conditions would be similar to existing conditions at 13th Street under the Alternative 2 Project. The Proposed Project is subject to SCRRA approval and as such the Proposed Project will comply with all applicable operational rail crossing safety improvements with respect to control point locations, crossing signals and gates to minimize disruptions to both vehicular, pedestrian and train circulation. No further analysis of this issue is warranted at this time. COMMENT 12.35 Placerita Canyon Road is a private road located wildfire/fire [sic] hazard zone, and is gated on its eastern end. While the gate is supposed to be open during emergencies, that has not always been the case, requiring residents to cross over the railroad. RESPONSE TO COMMENT 12.35 The commenter's concerns have been noted for the record and will be forwarded to the decision makers for their consideration. The operation of the private gate on the east end of Placerita Canyon is the responsibility of the PCPOA and is not related to the scope of the Proposed Project. The commenter does not raise any issues related to the DEIR; as such, no further response is required. COMMENT 12.36 In summary, the Lyons Avenue Project DEIR has not met CEQA requirements. It has not properly evaluated the Dockweiler Project in conjunction with the Lyons Project. The Lyons Project creates its Lyons Avenue/Dockweiler Drive Extension Project Final EIR 3. Responses to Comments State Clearinghouse No. 2013082016 Page 3-53 City of Santa Clarita February 2018 own safety hazards, and will create a traffic hub that connects other major streets, but that foreseeable impact has not been fully evaluated. RESPONSE TO COMMENT 12.36 With respect to the commenter's references to the "Dockweiler Project" and the "Lyons Project," as separate but related projects, see Response to Comment 12.1. The commenter does not substantiate their claim that the proposed Project will create a traffic hub with foreseeable impacts that have not been evaluated. As noted in Public Resources Code Section 21080(e) (2), substantial evidence does not consist of argument, speculation, unsubstantiated opinion or narrative, evidence that is clearly inaccurate or erroneous, or evidence of social or economic impacts that do not contribute to, or are not caused by, physical impacts on the environment. The commenter's opinion has been noted for the record and will be forwarded to the decision makers for their consideration. COMMENT 12.37 The alternative crossing at 13t'' Street will never obtain PUC approval, and is also inadequate. RESPONSE TO COMMENT 12.37 It is unclear whether the commenter is referring to the Alternative 1 or the Alternative 2 Project. Nonetheless, Alternative 1 evaluates the Proposed Project with the construction of a new at -grade railroad crossing at Lyons Avenue and Railroad Avenue and the retention of the 13th Street at -grade crossing. While it is acknowledged that the addition of an at -grade crossing without the removal of another grade crossing does not meet the Southern California Railroad Authority's policies, this alternative was analyzed and disclosed in the DEIR for informational purposes. Alternative 2 evaluates the roadway extension of Dockweiler Drive to 12th Street and does not include the extension of Lyons Avenue to Dockweiler Drive. Under Alternative 2, the existing at -grade railroad crossing at 13t'' Street would remain and would be improved. The commenter's opinion is noted for the record and will be forwarded to the decision makers for their consideration. COMMENT 12.38 The Market Street crossing is the only alternative which lessens but does not eliminate the major environmental burdens which adversely impact the rest of the community, and especially Placerita Canyon. RESPONSE TO COMMENT 12.38 As disclosed in the DEIR in Section 6.1, the Market Street Alternative was rejected from further consideration due to the physical constraints associated with grading, as well as the Alternative's incompatibility with respect to public safety and local residential street standards (See Section 6.1, page 6.1-2). Specifically, this alternative was rejected from further consideration due to the resulting 11.15% gradient of the roadway profile resulting from the existing topographical gradient between Market Street Lyons Avenue/Dockweiler Drive Extension Project Final EIR 3. Responses to Comments State Clearinghouse No. 2013082016 Page 3-54 City of Santa Clarita February 2018 and Dockweiler Drive and the relatively sharp curve at the base of an incline where the alignment would connect to Market Street. A gradient of 11.15% would not meet the street standards of a secondary highway and would potentially result in unsafe roadway conditions. Additionally, Market Street is a local residential street that directly abuts and provides access to single and multi -family residential land uses. The proposed alignment of Dockweiler Drive through this existing residential neighborhood would not be consistent with the alignment identified within the Circulation Element and would not be compatible with respect to public safety and local residential street standards. For this reason, this alternative alignment was rejected as infeasible. In response to public comments, the City of Santa Clarita re-examined the feasibility of an alternative route from Market Street to the proposed Dockweiler Drive roadway extension at The Master's University limits. As discussed in Section 2, Additions and Corrections, under the additional Market Street analysis, despite meeting a 6% grade, this alternative remains infeasible because it would not align with the proposed and approved terminus of Dockweiler Drive to The Master's University. Furthermore, this alternative would require the partial acquisition of 17 parcels, including the existing Newhall Metrolink Station, the Newhall Community Center and the Veteran Memorial Plaza to allow for a 92-foot right-of-way to comply with secondary highway roadway standards, which would disrupt the pedestrian - friendly character and transit oriented environment of Market Street, which is contrary to the objects identified in the Old Town Newhall Specific Plan. With respect to traffic impacts, as concluded in the Traffic Addendum Traffic Impact Analysis, prepared by David Evans and Associates (See Appendix B of this Final EIR), under the Market Street Alternative, Year 2019 project mitigation would include intersection modifications at Main Street (North -South) and Market Street (East-West). The intersection modifications would include installing a traffic signal. The north, south, east, and westbound directions would include a shared through -right turn lane. Intersection modifications at Newhall Avenue (North - South) and Market Street (East-West) would include removal of the traffic signal at the Newhall Avenue (North -South) and Market Street (West) intersection. The Newhall Avenue (North -South) and Market Street (East- West) intersections would be combined and converted to a multilane roundabout. The northbound direction would include a shared left -through lane and shared through -right lane. The southbound direction would include a left turn lane and a shared left -through -right lane. The eastbound and westbound directions would include a shared left -through -right lane. As discussed further, and shown in Table 6.5-1 Environmentally Superior Alternative Matrix, in Section 2 Additions and Corrections to the Draft EIR, the Market Street Alternative Project would result in significant unavoidable impacts with respect to air quality, land use and planning and noise. The Market Street Alterative Project may result in potentially significant impacts with respect to aesthetics and cultural resources. Additionally, the Market Street Alternative would result in slightly increased impacts with respect to traffic, as compared to the Proposed Project; however, with implementation of mitigation, traffic impacts would remain less than significant.

COMMENT LETTER No. 14 Judith and JC Burkhartsmeyer Date: October 2, 207 COMMENT 14.1 Thank you for the recent presentation to the Placerita Canyon Homeowners. My husband and I, 30 year residents of the Canyon, support the extension of Dockwieler so that Masters College can safely expand. But we feel that a connection to Market is much better than Lyons Avenue. -A RR [sic] crossing already exists at Market, and that area is a transportation hub. The grade for the Road [sic], and creek crossing is much easier than Lyons Avenue. -The RR [sic] crossing at 13th could remain open, allowing Canyon residents to maintain their primary exit. The crossing could be improved at a later time, as future development of the plot of land off 13th is developed. -Bringing traffic into downtown Newhall at Market, encourages drivers to become familiar with the shops and restaurants in the area, that the city has worked so hard to promote. Thank you for this opportunity to offer our opinion. Lyons Avenue/Dockweiler Drive Extension Project Final EIR 3.

COMMENT LETTER No. 15 Sandra Cattell October 16, 2017 COMMENT 15.1 Comments on the Dockweiler Extension DEIR I moved to Placerita Canyon 20 years because of the rural equestrian lifestyle it supports. I have 2 horses on the property. My home is very special to me. With that said, I believe the city has continually sidestepped the intention of the special standards district. The new Revelo project and mixed use being introduced into the neighborhood have promised to negatively change the neighborhood forever. This Dockweiler Extension will further the decline. RESPONSE TO COMMENT 15.1 This comment has been noted for the record and will be forwarded to the decision makers for their consideration. The commenter does not raise a specific issue with respect to the environmental analysis presented in the DEIR, and as such no further response is required. COMMENT 15.2 The proposed Lyons crossing was always a bad idea. It would have necessitated raising Railroad Ave and part of Lyons, dumped lots of traffic into the train track crossing and the Railroad/Lyons intersection, and would have created a traffic nightmare for this community. RESPONSE TO COMMENT 15.2 It is reasonable to assume that the commenter is referring to the previous DEIR that was prepared for the Lyons Avenue At -Grade Rail Crossing Project, which was published in 2010 (but was never certified) (See also Response to Comment 12.1). To clarify, the Proposed Project does not necessitate the re - profiling of the Railroad Avenue and Lyons Avenue intersection, as shown in Figure 2-9 Proposed Site Plan at Lyons Avenue, of the DEIR. The commenter does not raise a specific issue with respect to the Lyons Avenue/Dockweiler Drive Extension Project Final EIR 3.

COMMENT 15.3 Alternative 2, the extension of Dockweiler to 13'b Street is only a little better (and is the preferred by the DEIR, less encroaching alternative). RESPONSE TO COMMENT 15.3 As discussed in Section 6.5 of the DEIR, the Alternative 2 Project was selected as the Environmentally Superior Alternative, because it would reduce the footprint of the Project Site, as it excludes the Lyons Avenue Extension to Dockweiler Drive, and maintains the at -grade crossing at 13'b Street. No further response is required. COMMENT 15.4 Both alternatives will further erode the rural equestrian feel of the area, and of course, no one would want to ride their horse anywhere near the road. RESPONSE TO COMMENT 15.4 Both the Proposed Project and the Alternative 2 Project would not conflict with or alter any equestrian facilities or trails. To the contrary the Proposed Project would increase access in the PCSSD, as the proposed alignment of Dockweiler Drive would include a Class II Bike Route and pedestrian walkways. The Proposed Project and the Alternative 2 Project would be designed in accordance with the appropriate design features and standards required for secondary highways and railroad crossings. The Proposed Project would be subject to the site plan review requirements of the City of Santa Clarita. No further analysis is required. COMMENT 15.5 It will increase the traffic flows through our community to a shared track crossing. Your traffic study and its counts are 5 years old, and do not truly reflect the total picture of the traffic in this neighborhood. Long lines when there is a train! Long lines when church gets out (or before church)! These will be exacerbated by more trains and the new development, which most likely (no matter what your counts say) will double the traffic flows across the train tracks. Improvement at the 13th St. crossing will barely improve the built out situation without adding lots of Dockweiler traffic. RESPONSE TO COMMENT 15.5 As further discussed in Section 4.9 Transportation and Traffic, traffic counts were conducted in December 2012 and the Traffic Study was updated in 2017 (refer also to Traffic Impact Analysis: Dockweiler Drive Lyons Avenue/Dockweiler Drive Extension Project Final EIR 3. Responses to Comments State Clearinghouse No. 2013082016 Page 3-59 City of Santa Clarita February 2018 Alignment Project, Santa Clarita, CA, prepared by David Evans and Associates, dated August 8, 2017, included in Appendix H of the DEIR). With respect to future development, traffic projections are based on the General Plan Buildout. The buildout includes construction of future roadways including: Dockweiler Drive, between Railroad Avenue and Valle Del Oro; Magic Mountain Parkway, from Railroad Avenue to Via Princessa; and Via Princessa, between Claibourne Lane and Sheldon Avenue. This also includes the proposed conceptual development of the North Newhall area (809 dwelling unit plus an approximate 11-acre commercial land use). A comparison of the No Build scenario, the Proposed Project scenario, and the Alternative 2 Project scenario for Daily, A.M. and P.M. Peak hour traffic volumes were compiled for the Year 2019 and 2035 conditions as presented in Table 6.4-3 and Table 6.4-4, respectively (see page 6.4-28 of the DEIR). With respect to traffic counts at the 13th Street Crossing under the Alternative 2 Project, as presented in Table 6.4-3 under Alternative 2 Year 2019, the total average daily traffic for the Alternative 2 Project is anticipated to result in a reduction of 3,860 average daily trips at the 13'h Street crossing as compared to the No Build Condition. As presented in Table 6.4-4 under Alternative 2 Year 2035, the total average daily traffic for the Alternative 2 Project is anticipated to result in a slight increase of 730 average daily trips at the 13'h Street crossing as compared to the No Build Condition. The Alternative 2 Project would include infrastructure and traffic improvements to accommodate the proposed extension of Dockweiler Drive and improve vehicle and pedestrian safety and circulation. With implementation of mitigation, the Alternative 2 Project would result in reduced vehicle delays during A.M. and P.M. peak hours at the intersection of Railroad Avenue and 13th Street as compared to the No Build Conditions for both the 2019 and 2035 buildout year scenarios. This comment has been included in the record and will be forwarded to the decision makers for their consideration. No further analysis with respect to the environmental analysis is warranted. COMMENT 15.6 I am suggesting two outlets; an improved, widened, safe 13th St crossing for Placerita Cyn residents and the new mixed -use development, and a smaller connection to Railroad at Market St. It is possible if a gentle curving road is nested into the hillside. It will dilute the amount of traffic going onto the roadway at one time. And, it will protect the Special Standards District of Placerita Cyn, and its residents from extra traffic. I am not sure why it was dismissed and not included as an alternative when it truly can be accomplished. Of course, it might decrease the total flow of traffic on Dockweiler, and although you might not like that, it is the only safe way to have an extra traffic connection and preserve the safety of the people who live on Dockweiler. That community needs protection too. There is an affordable housing crisis, and the homes along Dockweiler and below are both moderate and lower income housing. Sometimes it takes a roommate or two to afford the rent. There are no sidewalks, and no place to park extra cars other than the street, so removing the lane of parking for widening the road is out of the question. Thank you for your consideration of my suggestions. Lyons Avenue/Dockweiler Drive Extension Project Final EIR 3.

An analysis of Alternative 2 is provided in Section 6, Project Alternatives, page 6.4-1, of the DEIR. With respect to the Market Street Alternative, as disclosed in the DEIR in Section 6.1, the Market Street Alternative was evaluated and rejected from further consideration due to the physical constraints associated with grading, as well as the Alternative's incompatibility with respect to public safety and local residential street standards (See Section 6.1, page 6.1-2 of the DEIR) (See also Response to Comment 12.38, above and Section 2, Additions and Corrections, under the Additional Market Street Alternative Analysis).

No further response is required. COMMENT LETTER No. 16 Jim Coffey October 16, 2017 COMMENT 16.1 Good morning Mike. I'm writing you with my Wife in copy to express our opinion of the pending Dockweiler extension in general, and as it relates to both Placerita Canyon Road and the Placerita Canyon neighborhood in general. Both Paige and I are 50 year residents of mostly Newhall, the last 17 of which have been in Placerita Canyon at our current home located at 21551 Placerita Canyon Road. We love our Special Standards District community, and like our neighbors there our goal is to protect it from any negative impact to ourselves or anyone else who created a home there. We're aware of the multiple Dockweiler extension options on the table, one of which I name as an option even though the City seems not to recognize it as one. We are very optimistic about Masters traffic to and from Dockweiler, as it should lighten the congestion on Placerita Canyon Road which is a source of aggravation often. That said, our formal opinion and request toward the Dockweiler extension is as follows: • New Lyons crossing and connection to Dockweiler with spurs to adjacent and/or adjoining streets affected. We are strongly opposed to this in any form. The crossing is far too costly and will negatively affect Old Town Newhall. With Newhall Avenue and Via Princessa pending, there is no reason to open such a major flow of traffic between Lyons and Sierra. Such traffic will negatively inhibit Placerita Canyon Residents in and out of the west end of the neighborhood. RESPONSE TO COMMENT 16.1 As discussed further in Section 4.9, Transportation and Traffic, of the EIR the Proposed Project would add an additional east -west connector to facilitate traffic between the downtown Newhall community and the neighborhoods to the east. The proposed alignment would be used by motorists to reduce travel time Lyons Avenue/Dockweiler Drive Extension Project Final EIR 3. Responses to Comments State Clearinghouse No. 2013082016 Page 3-61 City of Santa Clarita February 2018 or otherwise avoid congested intersections in the local area. The Proposed Project is anticipated to reduce vehicle delays at nine of the 16 study intersections analyzed during the A.M. and P.M. peak hours for the 2019 buildout year scenario and at 12 of the 16 intersections during the A.M. and P.M. peak hours for the 2035 buildout year scenario. Overall, the Proposed Project would reduce traffic congestion on local roadways and would reduce travel time. Thus, as concluded in the DEIR, with implementation of mitigation, the Proposed Project would reduce traffic congestion in the project vicinity and no further analysis is required. The commenter's opinion has been included in the record and will be forwarded to the decision makers for their consideration. COMMENT 16.2 • Expanded 13th Street crossing with connection to Dockweiler and associate connection(s) to 12th Street, Placerita Canyon et al. While we are less opposed to this than the new Lyons crossing, we are opposed to it again because of the traffic it will bring to the west end on our neighborhood. In the end, with this option our now overcrowded 13th Street crossing aka west end entry/exit will be worse off than it currently is even though widened. The "shortcut" created by this connection of Sierra Highway to 13th Street will be a traffic nightmare, especially when any Ravello or similar project is built out. As one of only two canyon exits, we're already in danger of getting out quickly and safely during an emergency. RESPONSE TO COMMENT 16.2 With respect to future development, traffic projections are based on the General Plan Buildout, which includes the proposed conceptual development of the North Newhall area (809 dwelling unit plus an approximate 11-acre commercial land use). The Alternative 2 Project would include infrastructure and traffic improvements to accommodate the proposed extension of Dockweiler Drive and improve vehicle and pedestrian safety and circulation. With implementation of mitigation, the Alternative 2 Project would result in reduced vehicle delays during A.M. and P.M. peak hours at the intersection of Railroad Avenue and 13'h Street as compared to the No Build Conditions for both the 2019 and 2035 buildout year scenarios. As discussed in Section 5.1 Impacts Determined to be Less Than Significant, on page 5.1-3, subheading Fire and Police Protection, of the DEIR, emergency access to the Placerita Canyon community would be facilitated through the Proposed Project's alignment, which is consistent with the City's adopted Circulation Element. The Proposed Project's alignment would be an improvement to the current access route into the Placerita Canyon community via 13th Street. As stated in Comment Letter No. 5, the Los Angeles County Sheriff's Station generally supports public improvements similar to that of the Proposed Project because these improvements typically result in an overall positive impact upon law enforcement patrol operations, emergency access, and response times. (See Comment Letter No. 5, above). The commenter's opinion has been included in the record and will be forwarded to the decision makers for their consideration. No further analysis is warranted.

Responses to Comments State Clearinghouse No. 2013082016 Page 3-62 City of Santa Clarita February 2018 COMMENT 16.3 • No Dockweiler extension past connection to Masters. We would be in favor of this, since the true goal of any Dockweiler extension should be to gain proper access and traffic flow in and out of Masters' campus as necessary to avoid negative impact to the Placerita Canyon residents and neighborhood. RESPONSE TO COMMENT 16.3 This comment has been noted for the record and will be forwarded to the decision makers for their consideration. The commenter does not raise a specific issue with respect to the environmental analysis presented in the DEIR, and as such, no further response is required. COMMENT 16.4 • Dockweiler connection to Market Street. We are in favor of and request this option. We call this an option because it is, even though it would require a few steps back to realign the current approved Dockweiler extension. As a good neighbor should, Masters should allow such a realignment as long as it doesn't negatively impact their new entry/exit. This option will allow direct access to Old Town Newhall for Masters, as well as provide an additional general entry and exit to Old Town Newhall from an additional point of access. Everyone benefits from this option, and other than some additional preconstruction prep and process work there is no downside. Thank you for receiving our formal comments and opinion. Kindly acknowledge your receipt of this and formal entry into the EIR documents. RESPONSE TO COMMENT 16.4 As disclosed in the DEIR in Section 6.1, the Market Street Alternative was evaluated and rejected from further consideration due to the physical constraints associated with grading, as well as the Alternative's incompatibility with respect to public safety and local residential street standards (See Section 6.1, page 6.1-2 of the DEIR).

[sic] I know that a 13a' St crossing closure would certainly create horrendous additional traffic problems. An at grade crossing at Lyons Ave. is a non -workable engineering fiasco. A Dockweiler extension and connection to the existing Marker St. Crossing would do nothing to alleviate any increase in local traffic flow without [sic] a connection to the northerly side of the railroad in the vicinity of Arch St. & thence [sic] to Dockweiler. Another important road improvement need is for our city to give Placerita Canyon residents a connection to an extended Golden Valley Road, as a safety escape route of this area in the event of a serious threat of fire or flooding. Please leave the 13a' St crossing functioning but with an improved egress "right turn lane" at the crossing. It is hazardous at the present time.

The commenter's opinion has been included in the record and will be forwarded to the decision makers for their consideration. COMMENT 20.2 Why is the city fixated on another "east -west" connection at this location? Is it simply because it was in the General Plan to make this happen? If that is the case, we need to amend the General Plan before we build Dockweiler, as a route to nowhere, or the Santa Clarita Parkway. The blatant fact is that we already have an east -west connection. It's Newhall Avenue! If Dockweiler is an east -west connection, so is Newhall Avenue. The absurdity of building and using Dockweiler is that Dockweiler and Newhall Avenue parallel each other and are only one-half mile apart. RESPONSE TO COMMENT 20.2 As discussed in Section 2, Project Description (see page 2-28), of the DEIR, the purpose of the Proposed Project is to achieve CPUC approval of an at -grade rail crossing at the current terminus of Lyons Avenue and the Southern Pacific Railroad line and extend a through roadway connection from Lyons Avenue to Dockweiler Drive. Additionally, as noted in the DEIR, the proposed connection and extension of Lyons Avenue to Dockweiler Drive is identified in the Circulation Element of the City's General Plan as one of the primary east -west arterials through the City of Santa Clarita that would provide a through connection from Sierra Highway to Railroad Avenue. The Proposed Project is being developed to facilitate the increase in vehicles and relieve congestion in the project area as build out of the General Plan continues. As identified in DEIR, objectives of the Proposed Project include: • Implementation of the goals of the Circulation Element of the Santa Clarita General Plan, including the crossing at Lyons Avenue and the extension of Lyons Avenue/Dockweiler Drive; • Improve roadway level of service and circulation network; Provide a safe and efficient at -grade rail crossing that meets the standards of the California Public Utilities Commission (CPUC); • Provide sufficient information for CPUC application and approval of the proposed crossing; • Improve pedestrian and vehicle railroad safety by eliminating an existing substandard at -grade rail crossing at 13a' Street and replacing it with a more advanced and enhanced at -grade rail crossing at Lyons Avenue; • Reduce vehicle miles traveled by creating a more direct route for motorists, eliminating circuitous driving patterns. • Provide greater connectivity between Old Town Newhall, Placerita Canyon, The Master's University and the residents that live along Dockweiler Drive; • Provide an economic stimulus to Old Town Newhall with enhanced connectivity to the Old Town Newhall area; and Lyons Avenue/Dockweiler Drive Extension Project Final EIR 3. Responses to Comments State Clearinghouse No. 2013082016 Page 3-66 City of Santa Clarita February 2018 • Provide an enhanced gateway to Placerita Canyon. The purpose of the EIR is to analyze the environmental impacts that would result from the construction and operation of the Proposed Project and analyze alternatives to the Proposed Project that may be effective in reducing or avoiding environmental impacts. This comment has been noted for the record and will be forwarded to the decision makers for their consideration. No further response is required. COMMENT 20.3 The positives of using Newhall Avenue are the following: • It is already built. • Newhall Avenue extends and/or starts at an existing freeway on and off ramp. • Newhall Avenue does not go through any residential neighborhoods. • Newhall Avenue does not cost the city anything. The negatives of using Newhall Avenue are zero. The only positive of using and building Dockweiler is that it may be a better entrance and exit to Masters' College future building expansion, which would be in addition to an existing route to Newhall Avenue already planned by the college. It can be argued that it provides a faster route to the northern part of the east side of the Santa Clarita Valley. However, this is highly debatable as Newhall Avenue provides a north -south freeway on -ramp to this portion of the eastern portion of the Valley, which may take the same amount of time, or at worst approximately the same amount of time. The negatives of building and using Dockweiler as an east -west route are the following: • The cost of building and maintaining a new road. Some costs, but not all, include the "mitigation" measures for 13t'' street, the railroad crossing upgrades, Placeritos, and Placerita Canyon, the road and signal modifications on Railroad Avenue to enable north and south bound traffic proper access to 13th street. • The road does not serve any benefit, as its primary function would be for the east to the west traffic. However, this route ends at Sierra Highway, with no freeway on or off -ramp access. Traffic traveling south from Dockweiler would turn south and continue on Sierra Highway to the intersection of Newhall Avenue and Sierra Highway. Ironically, this is the same terminus as the Newhall Avenue route! • There would be very little benefit for traffic that wanted to travel north from the intersection of Dockweiler and Sierra Highway, as the distance from 13th street to Dockweiler to Sierra Highway is greater that the distance from 13th Street to the intersection of Newhall Avenue and Sierra highway. • Repercussions for and from the community for making the land at the intersection of 13th Street and Railroad Avenue available for large scale development would be egregious. As a case in point, when the city was considering a Metro Link station at this intersection it was deemed untenable and not in the best interest of the community or Newhall or Placerita Canyon. Lyons Avenue/Dockweiler Drive Extension Project Final EIR 3. Responses to Comments State Clearinghouse No. 2013082016 Page 3-67 City of Santa Clarita February 2018 Additionally, a large scale development's traffic impact on this portion of entrance to Dockweiler would make this an F grade road and intersection. RESPONSE TO COMMENT 20.3 The commenter's opinions regarding the use of Newhall Avenue are noted for the record and will be forwarded to the decision makers for their consideration. The commenter does not raise specific concerns related to the environmental analysis as presented in the DEIR. Nonetheless, as discussed further in Section 4.9, Transportation and Traffic, of the EIR the Proposed Project would add an additional east - west connector to facilitate traffic between the downtown Newhall community and the neighborhoods to the east. The proposed alignment would be used by motorists to reduce travel time or otherwise avoid congested intersections in the local area. The Proposed Project is anticipated to reduce vehicle delays at nine of the 16 study intersections analyzed during the A.M. and P.M. peak hours for the 2019 buildout year scenario and at 12 of the 16 intersections during the A.M. and P.M. peak hours for the 2035 buildout year scenario. Overall, the Proposed Project would reduce traffic congestion on local roadways and would reduce travel time. Thus, as concluded in the DEIR, with implementation of mitigation, the Proposed Project would reduce traffic congestion in the project vicinity, and no further analysis is required. COMMENT 20.4 • The importance of Placerita Canyon's rural nature and the preservation of one of the last symbols of Newhall's history were confirmed with the establishment of a Special Standards District by the City, which states: o The purpose of the Placerita Canyon special standards district (PCSSD) is to protect, maintain, preserve and enhance the secluded, rural equestrian character of the community, to enhance the community's unique appeal and to help mitigate the cumulative impacts of residential development. Additionally, it is the purpose of these special standards to ensure that new and expanded structures are compatible with the characteristics of surrounding single-family residential neighborhoods, and protect the light, air, and privacy of existing single-family residences from negative impacts. These standards are also intended to ensure reasonable access to public riding and hiking trails, and to minimize the need for installation of infrastructure such as sewers, streetlights, concrete sidewalks and concrete flood control systems that would alter the community's character, while providing for adequate drainage and other community safety features. • This route and future mass development of this area of the Canyon is contrapositive to the preservation, and the city's original intent, for the community of Placerita Canyon. RESPONSE TO COMMENT 20.4 The commenter does not provide any specific examples of how the Proposed Project would be in conflict with the provisions of the PCSSD, which are established in Chapter 17.39. 020, of the SCMC. The DEIR Lyons Avenue/Dockweiler Drive Extension Project Final EIR 3. Responses to Comments State Clearinghouse No. 2013082016 Page 3-68 City of Santa Clarita February 2018 included a detailed analysis evaluating the consistency of the Proposed Project to the specific applicable development standards for the PCSSD area. As analyzed in Section 4.7, Table 4.7-3, page 4.7-18, of the DEIR, the Proposed Project is in substantial compliance with the standards identified in the PCSSD. This comment letter will be included in the record and will be forwarded to the decision makers for their consideration. No further response is required. COMMENT 20.5 • No study exists as to the importance or need to build a secondary route to Sierra Highway at this location at this time. • It does not benefit the community of Valencia or the east side of the Santa Clarita Valley, which presently utilizes Newhall Ranch Road and Soledad Canyon Road. RESPONSE TO COMMENT 20.5 With respect to the commenter's concerns regarding the purpose and function of the Proposed Project, please refer to Response to Comment 20.2 and 20.3 above. No further response is required. COMMENT 20.6 So, what is the solution, and why did the EIR not include an alternative route in their report? The solution, if needed at this time, is to build that portion of Via Princessa from the existing terminus of Via Princessa (in circle J Ranch), to Golden Valley Road, at the future and planned intersection of Via Princessa and Golden Valley Road. The benefits of this route are as follows: • It adheres to the General Plan as the planned major east west connection for the valley • It has an existing bridge crossing spanning Railroad Ave. and the train tracks. • It serves the communities of Valencia and Newhall and the eastern communities of the valley, including Vista Canyon and most developments in that area. • The cost of this road will be repaid by future developers, as mandated in their Conditions of Approval. • The distance of connecting from the present terminus in Circle J to Golden Valley Road is less than the distance from 13th Street to the terminus of Dockweiler (1.2 miles to 1.5 miles). • Will lessen the traffic impact on Railroad Ave., Newhall Ave and Soledad Canyon. The negatives of building this route are as follows: • None, as it is the planned major east -west connecter route of the General Plan, evidenced by the completed construction of the Wiley Canyon Bridge. Why didn't the EIR include this alternative in their report? I don't know. Lyons Avenue/Dockweiler Drive Extension Project Final EIR 3. Responses to Comments State Clearinghouse No. 2013082016 Page 3-69 City of Santa Clarita February 2018 RESPONSE TO COMMENT 20.6 As discussed in Section 6.1 Project Alternatives Introduction, of the DEIR, the objective of the project alternatives analysis, as directed by CEQA, is to identify alternatives that could feasibly attain most of the basic objectives of the project but would avoid or substantially lessen any of the significant effects of the project, and evaluate the comparative merits of the alternatives. Objectives of the Proposed Project are discussed in Section 2 Project Description (see page 2-28), of the DEIR, and are also listed above in Response to Comment 20.2. The DEIR does not consider the extension of Via Princessa as an alternative because this extension would be an entirely different project as it does not analyze the extension of Dockweiler Drive as shown on the General Plan, and therefore does not meet the objectives of the Proposed Project. No further response is required. COMMENT 20.7 Nothing exists as to why a second route at the Dockweiler location is needed at this time. Additionally, the EIR did not mention Newhall Avenue as an alternative to Dockweiler, nor did they mention Via Princessa. Everything should stop [sic] until a full analysis, with community participation, of constructing a section of Via Princessa is completed: as well as an in depth study of why we need an additional east -west connection at this time paralleling Newhall Ave [sic] RESPONSE TO COMMENT 20.7 With respect to the commenter's concerns regarding the purpose and function of the Proposed Project, please refer to Response to Comment 20.2 and 20.3 above. With respect to Project alternatives, please refer to Response to Comment 20.3 and 20.6, above. This comment letter will be forwarded to the decision makers for their consideration. No further response is required. COMMENT LETTER No. 21 Tony Matthess Date: October 3, 2017 COMMENT 21.1 In response to Ken Striplin's letter to me, I want to express my gratitude for having the opportunity to put forward my objections to the Dockweiler Extension at this time. I have lived in the canyon for over 40 years; 31 in Placerita Canyon. I am a past Board Member of the PCPOA, and with the help of Buck McKeon, was personally instrumental in moving the proposed Metrolink Placerita station to Soledad Canyon, Rd. I have been involved in the real estate industry in Santa Clarita since 1972, including starting and owning a real estate sales company in the 70's, forming a real estate development and construction company in the 80's, entitling and building several residential and commercial developments in the Santa Clarita, and starting Valencia National Bank in 1985. The Lyons Avenue/Dockweiler Drive Extension Project Final EIR 3. Responses to Comments State Clearinghouse No. 2013082016 Page 3-70 City of Santa Clarita February 2018 reason for describing my personal involvement in the city during my 40+ years in Santa Clarita is meant to assure you that my opposition to the Dockweiler Extension is not a rant. After taking part in the community meeting held at Masters College last Thursday evening, it was evident the PCOPA board members that were there, and several of the most vocal homeowners in attendance, unfortunately spent most of their time on the minutiae of the Dockweiler Extension issue. Additionally, after meeting with several Placerita Canyon homeowners in attendance and over 20 that were not in the meeting, the "Board" is not aligned with our position, and misrepresenting the majority of the homeowners in the Placerita Canyon area. RESPONSE TO COMMENT 21.1 This comment has been noted for the record and will be forwarded to the decision makers for their consideration. The commenter does not raise a specific issue with respect to the environmental analysis presented in the DEIR, and as such no further response is required. COMMENT 21.2 It is our position that the focus of the Dockweiler EIR does not address the merits of not building Dockweiler at this time. Those, but not all, are the following: • Why should Dockweiler be built at this time? Newhall Ave is not impacted at this time and Newhall proper is built -out. Therefore, traffic from Newhall or the surrounding area of Newhall will not increase enough to warrant another east -west connection at this location at this time, RESPONSE TO COMMENT 21.2 With respect to the commenter's concerns regarding the purpose and function of the Proposed Project, please refer to Response to Comment 20.2 and 20.3 above. This comment will be forwarded to the decision makers for their consideration. No further response is required. COMMENT 21.3 • Via Princessa would serve as a better east -west connection for the following reasons: o It serves the communities of Valencia, Newhall, Circle J, Valencia Town Center and other commercial and office communities of Valencia on the west side of the city. o It serves the communities on the east side of the city, such as Vista Canyon, Sand Canyon Plaza, Sand Canyon, Fairoaks, Friendly Valley, developments boarding Via Princessa, Sierra Highway and Golden Valley, and the commercial developments at Sierra Highway, Via Princessa and Golden Valley, along with those traveling on the Antelope Valley freeway. o The overpass of Sierra Highway and the railroad is already constructed via the Wiley Canyon Bridge. Lyons Avenue/Dockweiler Drive Extension Project Final EIR 3. Responses to Comments State Clearinghouse No. 2013082016 Page 3-71 City of Santa Clarita February 2018 It should also be noted that very few people throughout the city, including staff at the Signal newspaper, have any awareness of the Dockweiler Extension. It is my belief that if the general public was aware that the city was contemplating building out Via Princessa, you would have thousands of people responding. In all good conscience, and for the benefit of the whole City of Santa Clarita, an EIR on completing the construction of Via Princessa to Golden Valley prior to building the "Dockweiler Extension" is paramount.

This comment letter will be forwarded to the decision makers for their consideration. No further response is required. COMMENT LETTER No. 22 Joe Morelli Date: September 14, 2017 COMMENT 22.1 Please look at Market St. again and use Pine St. as a second [sic] as well as Dockweiler Drive. If you use Market onto Dockweiler Pine St. does not cross the RR [sic] tracks and any one can get out to Railroad at the end of Pine St. Also Pine St. [sic] is already there to use along with a light at the end of Pine to Railroad. RESPONSE TO COMMENT 22.1 As disclosed in the DEIR in Section 6.1, the Market Street Alternative was evaluated and rejected from further consideration due to the physical constraints associated with grading, as well as the Alternative's incompatibility with respect to public safety and local residential street standards (See Section 6.1, page 6.1-2 of the DEIR).

COMMENT No. 24 Candice Nelson Date: October 15, 2017 COMMENT 24.1 After analyzing the DEIR for the Proposed Lyons Avenue/ Dockweiler Drive Extension the following questions and concerns have sparked my attention: 1) How will all of the properties needed for the construction of the extension be obtained? Will the needed properties be completely acquired by the City of Santa Clarita, or will only the necessary portions needed for the extension be acquired, either by purchase and re -zoning property lines or leasing the needed portion of the property from the owner? RESPONSE TO COMMENT 24.1 Implementation of the Proposed Project may require the potential acquisition of easements over public and private properties that are adjacent to the proposed alignment. Figure 2-18, Dockweiler Drive Study Area — Adjacent Properties Map (see page 2-27 of the DEIR), identifies properties in the project area that are located within or adjacent to the proposed alignment. Table 2-1 of the DEIR (see page 2-24), identifies a total of 19 of the 29 properties identified within the study area would be affected by easements Lyons Avenue/Dockweiler Drive Extension Project Final EIR 3. Responses to Comments State Clearinghouse No. 2013082016 Page 3-73 City of Santa Clarita February 2018 and or acquisitions. The commenter does not raise a specific issue with respect to the environmental analysis presented in the DEIR, as such no further response is required. COMMENT 24.2 2) With the Dockweiler extension, Valle del Oro has a direct connection into Placerita Canyon. With such access, how will The City of Santa Clarita, as well as the Santa Clarita Sheriffs Station enforce and prevent a non -avoidable increase in crime rates. The current layout of Placerita Canyon allows a one-way entrance and exit, resulting in an extremely low rate of crime. However with this connection, there are multiple entrances and exits providing a higher chance of crime. When looking at recent crime maps, the neighborhood surrounding Valle del Oro has numerous incidents (including the recent Lyons Ave. road closure involving LAPD and an armed robbery suspect), while Placerita Canyon has extremely low crime reports. RESPONSE TO COMMENT 24.2 The portion of Dockweiler Drive that would extend to Valle del Oro is beyond the scope of the Proposed Project. The Proposed Project analyzes the extension of Dockweiler Drive from Arch Street to the limits at The Master's University. Refer to Figure 2-1, Project Location Map, of the DEIR. Nonetheless, with respect to the commenter's concerns regarding crime, for purposes of CEQA, a significant impact may occur if the Los Angeles County Sheriffs Department ("LASD") could not adequately serve the areas affected by the Project's circulation plan based upon response time or access. LASD reviewed and commented on the DEIR. (See Comment Letters No. 5, above). As noted in Comment Letter No. 5, the Station generally supports these types of public improvements like the Proposed Project because these improvements typically result in an overall positive impact upon law enforcement patrol operations. No further response is required. COMMENT 24.3 3) When reading the DEIR, all options for the project are said to "avoid direct impact to Placerita Canyon". After analyzing the options, I feel that all rather provide a "direct impact" to Placerita Canyon. Whether it is from a non -avoidable increase in crime, traffic, or the loss of the rural equestrian lifestyle that we all have worked very hard to preserve, this extension will result in a detrimental decline of a neighborhood that is proud of the historical importance it holds. RESPONSE TO COMMENT 24.3 The DEIR does not claim to "avoid direct impacts to Placerita Canyon" as stated by the commenter. The Proposed Project's impacts with respect to each category, pursuant to CEQA, were fully analyzed and disclosed in the DEIR. A summary of each impact category and its impact conclusion is provided in Section 1. Executive Summary of both the DEIR and Final EIR. With respect to impacts related to crime, refer to Response to Comment 24.2. With respect to traffic impacts, refer to Response to Comment 20.3. With respect to the Proposed Project's consistency with the PCSSD and impacts to equestrian uses, please refer to Response to Comments 12.3 and 12.4, respectively.

I recently learned about a proposal to connect Dockweiler Drive to 13a' Street, Lyons Avenue, or Market Street to decrease the traffic on Newhall Avenue. I believe that the problem isn't lying in the traffic on Newhall Avenue, it is the traffic on the 5 and 14 freeways. Many commuters that drive down Newhall Avenue are not driving to Newhall, they are driving to Valencia, Saugus, or other parts of Santa Clarita. The major intersections in Newhall are two and three lanes wide on each side while the intersections in Valencia are around six. You see a fraction of the cars driving through Newhall compared to Valencia. Newhall Avenue is the first exit off the freeway and people would rather get off to drive on side streets than sit on the freeway in stop and go traffic. My point is that possibly the traffic situation would improve if the residents in the Northern part of Santa Clarita had an easier way to commute to and from their homes. Widening the freeways or improving the off ramps near their homes would be more effective for the future and eminent growth of this city. I have lived in Placerita Canyon long enough to remember the days before the gate was installed on our street. As kids, we weren't allowed to go outside our fence at any time because the traffic was terrible and too dangerous. After the gate was installed it changed our lives completely. Placerita Canyon became a neighborhood that some of us had never experienced before. I remember looking out the window and couldn't believe when I saw people walking their dogs on the street! My dad started taking us for bike rides in the evening and that was the first time we were ever able to do that together. For once we could ride our horses and bicycles safely across the street to the little market for ice cream on a warm summer day. To this day I walk down the street with my horse and come across families on bicycles, elderly neighbors dropping off their farm fresh eggs at friends' houses, and people that I would have never even met before walking their dogs. My stand on the proposal is for the "No Build" option. To turn nice quiet residential neighborhoods into major thoroughfares with large amounts of traffic in order alleviate traffic elsewhere is unfair. It is not the responsibility of the residents to solve commuter problems and the issues should be addressed elsewhere. Every person should be able to raise their kids in a nice neighborhood without the concern of their safety. Please take this letter into consideration before moving forward with these proposals.

I have lived in this canyon for over 34 years. There is a quality of life in our canyon that is rare and hard to find elsewhere in the city. By dumping Dockweiler, Casden, and additional Master's College vehicles into the canyon you are greatly disrupting our "quality of Life"! There are several issues I would suggest you review/re-review. RESPONSE TO COMMENT 30.1 This comment has been noted for the record and will be forwarded to the decision makers for their consideration. Responses to the commenter's concerns are provided below. No further response is required. COMMENT 30.2 1). What is the impact of the increased population of Master's College. More students equal more cars equal more traffic. They need an entrance/exit off of Railroad Avenue. Lyons Avenue/Dockweiler Drive Extension Project Final EIR 3. Responses to Comments State Clearinghouse No. 2013082016 Page 3-78 City of Santa Clarita February 2018 RESPONSE TO COMMENT 30.2 As discussed further in Section 4.9 Transportation and Traffic, traffic projections included the construction of future roadway: Dockweiler Drive, between Railroad Avenue and Valle Del Oro. The commenter's opinion has been noted for the record and will be forwarded to the decision makers for their consideration. The commenter does not raise a specific issue with respect to the environmental analysis presented in the DEIR, as such no further response is required. COMMENT 30.3 2). What is the impact of the studio overlay for filming in the Canyon? In addition to Melody Ranch's filming, there has been a huge increase of additional filming in the canyon. Within the last month I have been stopped on Placerita Canyon Road (the private portion) and not allowed to go through until their filming shot was done. There is an additional impact into this canyon related to traffic just from the filming traffic and this is before the possibly additional vehicles are added from Dockweiler, Casden, and Master's. The increase in filming vehicles, trucks, van, etc. is also at a detriment to our quality of life. The oversized trucks from the studios come barreling down the canyon at all hours of the day and night. They even come into contact with the oak trees this city works so hard to protect! What is the impact of all of this additional traffic prior to you adding more vehicles if the proposed option is adopted? RESPONSE TO COMMENT 30.3 An analysis of existing traffic conditions is presented in Section 4.9 Transportation and Traffic of the DEIR. With respect to traffic modeling, Year 2019, or opening year, traffic volumes were provided by the City of Santa Clarita using the Santa Clarita Valley Consolidated Traffic Model ("SCVCTM"). Other area projects anticipated to be constructed by Year 2019 were incorporated into the SCVCTM and account for expected growth. Future Year 2035 utilizes the traffic volume projections for the City of Santa Clarita's traffic model together with the existing traffic flow data. The traffic projections are based on the General Plan Buildout. The buildout includes construction of future roadways: Dockweiler Drive, between Railroad Avenue and Valle Del Oro; Magic Mountain Parkway, from Railroad Avenue to Via Princessa; and Via Princessa, between Claibourne Lane and Sheldon Avenue. This also includes the proposed conceptual development of the North Newhall area (809 dwelling unit plus an approximate 11-acre commercial land use). No further analysis is required. COMMENT 30.4 3). Additionally - what is the impact of accidents on the local freeways? Well I can tell you what happens. Railroad Avenue backs up and trying to get out of Placerita Canyon takes a long time. If you add vehicles from Dockweiler, Casden, and Master's College to this scenario it will be and [sic] even larger nightmare. While everyone is always affected by traffic accidents, it is unfair to put the residents of Placerita in an even worse position. On October 5 and October 10 of this year there were accidents of the southbound 5 freeway. Both days saw the traffic on Railroad Avenue back up and left Placerita Canyon residents waiting for multiple lights to get out of the canyon. Again everyone is affected by accidents buy [sic] this Lyons Avenue/Dockweiler Drive Extension Project Final EIR 3. Responses to Comments State Clearinghouse No. 2013082016 Page 3-79 City of Santa Clarita February 2018 option will make it three times worse for the canyon which I don't believe is fair or the correct thing to do. There are other options that make more sense. RESPONSE TO COMMENT 30.4 As discussed further in Section 4.9, Transportation and Traffic, of the DEIR, because the Proposed Project would add an additional east -west connector to facilitate traffic between the downtown Newhall community and the neighborhoods to the east, the proposed alignment would be used by motorists to reduce travel time or otherwise avoid congested intersections in the local area. The Proposed Project is anticipated to reduce vehicle delays at nine of the 16 study intersections analyzed during the A.M. and P.M. peak hours for the 2019 buildout year scenario and at 12 of the 16 intersections during the A.M. and P.M. peak hours for the 2035 buildout year scenario. Overall, the Proposed Project would reduce traffic congestion on local roadways and would reduce travel time. As concluded in the DEIR, with implementation of mitigation, the Proposed Project would reduce traffic congestion in the project vicinity. No further analysis is required. COMMENT 30.5 Suggestions: I would highly recomend [sic] using the Market Street crossing. There is already more infrastructure at that intersection to handle the amount of vehicles. Cars could go left, right or straight as opposed to only having the option of going left or right with the 13a' street option. Another suggestion would be to spend our hard earned tax payer [sic] money on completing Via Princessa. Have the Casden properties connect with Via Princessa to the North and leave Dockweiler alone. If you must do something with Dockweiler have it connect at Market Street which is better able to handle the traffic. RESPONSE TO COMMENT 30.5 As disclosed in the DEIR in Section 6.1, the Market Street Alternative was evaluated and rejected from further consideration due to the physical constraints associated with grading, as well as the Alternative's incompatibility with respect to public safety and local residential street standards (See Section 6.1, page 6.1-2 of the DEIR). See also Response to Comment 12.38, above, and Section 2. Additions and Corrections, Market Street Alignment Additional Analysis. This comment has been noted for the record and will be forwarded to the decision makers for their consideration. No further response is required. COMMENT 30.6 Lastly, I just would ask that you not ruin the Placerita Canyon way of life. Since this city was incorporated all I hear about is the Quality of Life [sic] that we enjoy and need to protect. Well, please practice what you preach and don't ruin our "Quality of Life"!

We appreciate you holding the meeting, but aren't really sure you came with an open mind and ears to LISTEN to what the community was saying. RESPONSE TO COMMENT 31.1 This comment has been noted for the record and will be forwarded to the decision makers for their consideration. The commenter does not raise a specific issue with respect to the environmental analysis presented in the DEIR, and as such no further response is required. COMMENT 31.2 A very compelling question asked, that was not answered very clearly, was "Why this project at all?" It doesn't make sense to divide traffic in one area, just to bring it back together a mile or two later. Is TMU still even planning to do their previously approved plan? That is another discussion that needs to be had. RESPONSE TO COMMENT 31.2 With respect to the purpose and objectives of the Proposed Project, please refer to Response to Comment 20.2. No further analysis is warranted. COMMENT 31.3 We were also very disappointed that the idea of bringing Dockweiler to Market Street, which already has a large RR [sic] crossing was not readily discussed. This seems like such a natural solution. It seemed that many of the residents were more favorable toward this crossing than the other crossing options. Lyons Avenue/Dockweiler Drive Extension Project Final EIR 3. Responses to Comments State Clearinghouse No. 2013082016 Page 3-81 City of Santa Clarita February 2018 RESPONSE TO COMMENT 31.3 As disclosed in the DEIR in Section 6.1, the Market Street Alternative was evaluated and rejected from further consideration due to the physical constraints associated with grading, as well as the Alternative's incompatibility with respect to public safety and local residential street standards (See Section 6.1, page 6.1-2 of the DEIR). See also Response to Comment 12.38, above, and Section 2. Additions and Corrections, Market Street Alignment Additional Analysis. The commenter's opinion regarding the Market Street Alternative has been noted for the record and will be forwarded to the decision makers for their consideration. No further response is required. COMMENT 31.4 Another question is, who owns the property that will need to be acquired for these projects? Are there any city officials, current or past, that could potentially profit from this Extension Project by selling their land for one or another of the projects and could that be why this is being ramrodded through? (i.e. LaureneWeste) RESPONSE TO COMMENT 31.4 Implementation of the Proposed Project may require the potential acquisition of easements over public and private properties that are adjacent to the proposed alignment. Figure 2-18, Dockweiler Drive Study Area — Adjacent Properties Map (see page 2-27 of the DEIR), identifies properties in the project area that are located within or adjacent to the proposed alignment. Table 2-1 of the DEIR (see page 2-24), identifies a total of 19 of the 29 properties identified within the study area would be affected by easements and or acquisitions. The commenter does not raise a specific issue with respect to the environmental analysis presented in the DEIR, as such no further response is required. COMMENT 31.5 If you have spent any time in the Canyon, you would understand what it is like already, to try and cross at 13a' Street after a train (of which there are many during the day). It is not uncommon for traffic to be backed up to Placeritos and beyond, just waiting to get across the tracks and on to Railroad Avenue. How many 1000s more cars do you hope to add to the mix? And what will happen when hundreds of houses and businesses are added to the mix on the corner of 13a' and Railroad? RESPONSE TO COMMENT 31.5 An analysis of existing traffic conditions is presented in Section 4.9, Transportation and Traffic, of the DEIR. With respect to traffic modeling, Year 2019, or opening year, traffic volumes were provided by the City of Santa Clarita using the Santa Clarita Valley Consolidated Traffic Model ("SCVCTM"). Other area projects anticipated to be constructed by Year 2019 were incorporated into the SCVCTM and account for expected growth. Future Year 2035 utilizes the traffic volume projections for the City of Santa Clarita's traffic model together with the existing traffic flow data. The traffic projections are based on the General Plan Buildout. The buildout includes construction of future roadways: Dockweiler Drive, between Lyons Avenue/Dockweiler Drive Extension Project Final EIR 3. Responses to Comments State Clearinghouse No. 2013082016 Page 3-82 City of Santa Clarita February 2018 Railroad Avenue and Valle Del Oro; Magic Mountain Parkway, from Railroad Avenue to Via Princessa; and Via Princessa, between Claibourne Lane and Sheldon Avenue. This also includes the proposed conceptual development of the North Newhall area (809 dwelling unit plus an approximate 11-acre commercial land use). No further analysis is required. The Proposed Project is anticipated to reduce vehicle delays at nine of the 16 study intersections analyzed during the A.M. and P.M. peak hours for the 2019 buildout year scenario and at 12 of the 16 intersections during the A.M. and P.M. peak hours for the 2035 buildout year scenario. Overall, the Proposed Project would reduce traffic congestion on local roadways and would reduce travel time. Thus, as concluded in the DEIR, with implementation of mitigation, the Proposed Project would reduce traffic congestion in the project vicinity, and no further analysis is required. COMMENT 31.6 Most of the City's decisions regarding this issue lack common sense, which makes the whole situation very suspect to those of us in the Canyon. We implore you to re -think this whole project, and if it MUST [sic] be done, take a long, hard look at using Market Street instead of creating bigger issues with those of us who pay taxes for your paycheck. Finally, our understanding is that there is a legal agreement with the residents of Placerita Canyon to keep the neighborhood rural, as it has been for decades. Perhaps that needs to be looked into as well. Again, please re -consider this outrageous project and the impact that it will have on those who have lived here for many years. RESPONSE TO COMMENT 31.6 The commenter has not provided any specific examples of how the Project is in conflict with the provisions of the PCSSD, which are established in Chapter 17.39. 020, of the SCMC. The DEIR included a detailed analysis evaluating the consistency of the Proposed Project to the specific applicable development standards for the PCSSD area. As analyzed in Section 4.7, Table 4.7-3, page 4.7-18, of the DEIR, the Proposed Project is in substantial compliance with the standards identified in the PCSSD. With respect to the Market Street Alternative, see also Response to Comment 12.38, above, and Section 2. Additions and Corrections, Market Street Alignment Additional Analysis.

My wife sent comments as well. I work for a large city and understand how all this works. We chose to live here for a reason, quiet, little traffic — the 16 years we have lived here we have seen the city is not our friend and has our best interests in mind aside from Mrs West making out on her property - Common since dictate, we dont want this connection to bring MORE traffic in — just to widen 13th Street crossing like it should be to be safe. This is BAD for use and Dockweiler residents. We dont want this — I think you got this from our well informed residents who pay taxes. [sic] Part 2 — We are voters, you are not listening to what we as high paying taxpayers in this canyon — We are here for a reason. All this is going to do — Common sense is to bring more traffic into this canyon. Government normally doesn't listen to people who they are elected by. We dont want any bld out — Save your money — fix crossing at 13th street [sic] Thank you RESPONSE TO COMMENT 32.1 For clarification purposes, the Proposed Project itself would not generate vehicle trips, as it does not include the development any residential, commercial or industrial uses. The Proposed Project is being developed to facilitate the increase in vehicles and relieve congestion in the project area as build out of the General Plan continues. This comment letter has been included in the record and will be forwarded to the decision makers for their consideration. The commenter does not raise a specific issue with respect to the environmental analysis presented in the DEIR, as such no further response is required. COMMENT LETTER No. 33 Tammy Skinner Date: September 15, 2017 COMMENT 33.1 I attended the meeting last night at Masters College. This extension project could ruin the quality of life we in Placerita Canyon appreciate and pay for. I heard many people say that is the reason they purchased their homes in Placerita Canyon (a special standards district established years ago when the city did not want to pay for the road). I also heard homeowners living off Dockweiler opposed to this project because of the increase in traffic that will impact their communities. Lyons Avenue/Dockweiler Drive Extension Project Final EIR 3. Responses to Comments State Clearinghouse No. 2013082016 Page 3-84 City of Santa Clarita February 2018 With the build -out of Santa Clarita I've watched it change tremendously over 25 years. I don't want the traffic and major access to our community that we've fought hard to protect. Placerita Canyon is a special place in Santa Clarita and should stay that way. We have The Masters University, Melody Ranch Studios and churches, along with homeowners here having horses, ranches, etc. I know the Disney Studios will be here soon across the 14 freeway. The rebirth of downtown Newhall is great and I love seeing the community coming together. The City of Santa Clarita seriously needs to reconsider this extension project to protect the Placerita Canyon residents that have lived here for decades, preserve some of our history and what brought people to Santa Clarita in the first place. RESPONSE TO COMMENT 33.1 The commenter does not provided any specific examples of how the Proposed Project would be in conflict with the provisions of the PCSSD, which are established in Chapter 17.39. 020, of the SCMC. The DEIR included a detailed analysis evaluating the consistency of the Proposed Project to the specific applicable development standards for the PCSSD area. As analyzed in Section 4.7, Table 4.7-3, page 4.7- 18, of the DEIR, the Proposed Project is in substantial compliance with the standards identified in the PCSSD.

COMMENT No. 34 Thomas Soracco Date: October 9, 2017 COMMENT 34.1 As briefly discussed at the Master's College meeting, I do believe that the Dockweiler connection is fatally flawed and that another "out of the box" solution should be both considered and explored. Fundamental Problems with Dockweiler First, let me state that if Dockweiler did not exist, in other words if there were just an undeveloped hill there, then I do not think anyone would consider this route. It is not only extremely expensive but it is also very disruptive to existing neighborhoods. RESPONSE TO COMMENT 34.1 This comment has been noted for the record and will be forwarded to the decision makers for their consideration. The commenter does not raise a specific issue with respect to the environmental analysis presented in the DEIR, and as such no further response is required. Lyons Avenue/Dockweiler Drive Extension Project Final EIR 3. Responses to Comments State Clearinghouse No. 2013082016 Page 3-85 City of Santa Clarita February 2018 COMMENT 34.2 More fundamentally, this route does not provide the traffic relief or begin to solve the traffic issues that are being considered. Leaving aside human or quality of life improvement goals, the end game of the Dockweiler extension would be to alleviate traffic and to smooth anticipated future circulation in the Valley. As I will outline later, this extension not only will not ease the anticipated traffic but, if built as planned, it will actually increase traffic "friction" with added stops, delays, blockages and inconvenient routings. RESPONSE TO COMMENT 34.2 The commenter's claim that the Proposed Project would not relieve congestion in the project vicinity is unsubstantiated. As discussed further in Section 4.9, Transportation and Traffic, of the DEIR, the Proposed Project would add an additional east -west connector to facilitate traffic between the downtown Newhall community and the neighborhoods to the east. The Proposed Project does not include any commercial or residential land uses that would generate additional traffic. Additionally, the proposed alignment would be used by motorists to reduce travel time or otherwise avoid congested intersections in the local area. Based on an evaluation of the Proposed Project is anticipated to reduce vehicle delays at nine of the 16 study intersections analyzed during the A.M. and P.M. peak hours for the 2019 buildout year scenario and at 12 of the 16 intersections during the A.M. and P.M. peak hours for the 2035 buildout year scenario. Overall, the Proposed Project would reduce traffic congestion on local roadways and would reduce travel time. Thus, contrary to the commenter's assertion, as concluded in the DEIR, with implementation of mitigation, the Proposed Project would reduce traffic congestion in the project vicinity and no further analysis is required. COMMENT 34.3 There are non -engineering issues created as well. The purpose here is not to expand upon these, but they are important and worthy of mention: • Very high cost of construction due to steep grades and mountain terrain. RESPONSE TO COMMENT 34.3 This comment has been noted for the record and will be forwarded to the decision makers for their consideration. The commenter does not raise a specific issue with respect to the environmental analysis presented in the DEIR, and as such no further response is required. COMMENT 34.4 • Irreversible negative impact upon wildlife (foxes, wild cats, hawks, rabbits, coyotes, deer, native snakes and such). Lyons Avenue/Dockweiler Drive Extension Project Final EIR 3. Responses to Comments State Clearinghouse No. 2013082016 Page 3-86 City of Santa Clarita February 2018 RESPONSE TO COMMENT 34.4 Impacts upon wildlife were analyzed in the Biological Resources Assessment (contained in Appendix D to the Draft EIR) and summarized in Section 4.3, Biological Resources. As noted in the DEIR, the Proposed Project would not result in significant impacts to wildlife. With the incorporation of mitigation measures 4.3-1 through 4.3-7, impacts upon wildlife resources would be less than significant. No further analysis is warranted. COMMENT 34.5 • Highly negative impact upon ridgeline view to the community, this will destroy the hillside ridges and contours that provide invaluable aesthetic value. RESPONSE TO COMMENT 34.5 As disclosed in Section 4.1 Aesthetics, and shown in Figure 4.1 on page 4.1-3 of the DEIR, the eastern segment of the Dockweiler alignment was previously approved under a separate project entitlement for The Master's University in 2009, which included a Ridgeline Alteration Permit for the eastern segment of this ridgeline. The grading limits of the Proposed Project would retain the gradual elevation profile of the base of the ridgeline. Views of the altered portion of the ridgeline would be visible from limited points along the public rights -of -way along Market Street and Race Street to the south of the Project Site. As a project design feature the grading plan incorporates landform grading practices to blend the manufactured slopes and required drainage benches into the natural topography to the maximum extent feasible. Plant materials will be utilized to protect slopes from slippage and soil erosion and minimize the visual effects of grading and construction on a hillside area. With incorporation of the project design features to develop and improve a new roadway extension that is consistent with the City's roadway design standards, the Proposed Project would result in a less than significant impact with respect to the loss of an aesthetic natural feature. No further analysis is required. COMMENT 34.6 • Loss of valuable open space and trails —currently there are several regularly used trails through the hills. RESPONSE TO COMMENT 34.6 Based on the grading footprint (see Figure 2-14 on page 2-22 of the DEIR) the Proposed Project will not result in direct impacts upon existing hiking or equestrian trails. To the contrary, the Proposed Project would improve pedestrian and cycling opportunities in the project vicinity. Dockweiler Drive would include sidewalks for pedestrian use and Class II bike lanes on each side. The Proposed Project will be designed in accordance with the appropriate design features and standards required for secondary highways and railroad crossings. No further response is required. Lyons Avenue/Dockweiler Drive Extension Project Final EIR 3. Responses to Comments State Clearinghouse No. 2013082016 Page 3-87 City of Santa Clarita February 2018 COMMENT 34.7 • Significant quality of life loss in both the Placerita Canyon and in the hilltop Vistas community. RESPONSE TO COMMENT 34.7 The commenter's opinion has been noted. The commenter does not raise a specific issue with respect to the environmental analysis presented in the DEIR, and as such, no further response is required. COMMENT 34.8 • And, as the Placerita Canyon residents have voiced, there is a significant risk of impeded emergency evacuation due to the layout of the proposed extension RESPONSE TO COMMENT 34.8 As discussed in Section 5.1 Impacts Determined to be Less Than Significant, page 5.1-3, subheading Fire and Police Protection, of the DEIR, emergency access to the Placerita Canyon community would be facilitated through the Project's alignment, which is consistent with the City's adopted Circulation Element. The Proposed Project's alignment would be an improvement to the current access route into the Placerita Canyon community via 13a' Street. As stated in Comment Letter No. 5, the Los Angeles County Sheriff's Station generally supports public improvements similar to that of the Proposed Project because these improvements result in an overall positive impact upon law enforcement patrol operations, emergency access, and response times. (See Comment Letter No. 5, above). No further analysis is warranted. COMMENT 34.9 A more practical approach would mitigate all of the above WHILE providing a more effective traffic flow solution as well. RESPONSE TO COMMENT 34.9 As disclosed in Section 4.1 of the DEIR, the Prosed Project's impacts on aesthetics including scenic vistas and visual character would be reduced to a less than significant level with implementation of mitigation measures 4.1-1 and 4.1-2. As disclosed in Section 4.3, Biological Resources, with incorporation of mitigation measures 4.3-1 through 4.3-7, impacts upon wildlife resources would be less than significant. As further discussed in Section 5.1 the Proposed Project's impact to emergency services including police and fire would be less than significant. Refer also to Responses to Comment 34.4 through 34.6 above. With respect to traffic, as concluded in Section 4.9 Transportation and Traffic, with implementation of mitigation measures 4.9-1 through 4.9-14, impacts would be less than significant. Refer to also to Response to Comment 20.3, regarding traffic flow and congestion. No further analysis is warranted. Lyons Avenue/Dockweiler Drive Extension Project Final EIR 3. Responses to Comments State Clearinghouse No. 2013082016 Page 3-88 City of Santa Clarita February 2018 COMMENT 34.10 Before I touch upon the reasons that the proposed extension will not achieve its purpose, let's state the purpose to ensure we are on the same page. There are two potential reasons for the extension: • One, that there is some other reason it is being done than for traffic flow mitigation, such as for expanded development in the hills or simply to finish up a dated plan from 20 years past. • Or, to improve traffic flow and allow for the increased development along the Railroad corridor. This is not just for current traffic but for future anticipated traffic as well. This is the purpose that makes the most sense and the purpose that has been stated, so we will proceed on this path. RESPONSE TO COMMENT 34.10 With respect to the overall purpose and objectives of the Proposed Project, please refer to Response to Comment 20.2. No further analysis is warranted. COMMENT 34.11 The basic problem is that the extension to Dockweiler does not solve this and is a poor solution to the problem. It will create a number of significant "stop" points throughout the area and will lead to further slows and congestions. These are the problematic stops: • Dockweiler via the Placerita entrance to Sierra Highway is a very poor route for a bypass. This route does not cleanly connect any of the flow lines of the Valley, it starts at a t-intersection and stops at a t-intersection—in effect taking one from nowhere to nowhere. • At each of these terminus points there will be a significant increase in stopped, jammed traffic. In less than a mile, along Railroad, there will now be 5 significant stops and adding this one as a major traffic outlet will add lengthy stops and delays. Then, adding the projected traffic increase, this corridor will be increasingly difficult to navigate. • The same is true at Sierra Hwy. Adding lengthy left turn signals and extending stop times will greatly increase the slows along that vital corridor, without achieving much in the way of smoothed traffic. There will be a secondary effect at the Newhall Ave South left turn as this lane will have to be extended and its time length increased. Yet in no way does this route provide easy entrance or exit flow to any desired points, as both ends don't lead anywhere or flow easily. • An analogy can be found in irrigation systems. Every time a turn is introduced this then creates friction, turbulence, slows and loss of pressure. The same is true in traffic, with the added caveat of introducing higher rates of accidents to the process. Lyons Avenue/Dockweiler Drive Extension Project Final EIR 3. Responses to Comments State Clearinghouse No. 2013082016 Page 3-89 City of Santa Clarita February 2018 • As amply discussed in the meetings, this routing will create heavy disruption and slows to the traffic flow in and out of the Placerita Canyon. Enough said. • The Dockweiler extension itself will be a very poor flow. First is the steep grade and potential curves on the route, this never makes for smooth, flowing traffic. Second is the number of stop signs that will be required along the route, minimally these are: at the entrance and exit to Master's College and a minimum of three stop signs through the community on top of the hill (Valle del Oro intersection, apartment exit at the east end and at the Lantana community). It will be very slow going through there. Added to this is the fact that traffic will be merging at both ends from two lanes to a single lane at the top of the hill. So, adding together the longer waits at traffic lights, the merging lanes, the multiple stop signs (or even an additional stop light) and the grades to the fact that this route is NOT convenient to any destination or flow, makes for a very expensive and ineffective plan. RESPONSE TO COMMENT 34.11 The commenter's opinions have been noted for the record. With respect to the Proposed Project's impacts on traffic flow and congestion, please refer to Response to Comment 20.3, above. No further response is required. COMMENT 34.12 TARGET ONE: Aside from a restricted corridor in downtown Newhall, the biggest issues lie in the number of stopping points along the way. These should be addressed and solved as a PRIMARY concern, this is low hanging fruit. Traffic that flows equates to reduced congestion and improved capacity. Proposed improvements would include: • Reposition the bus stop in front of the Metro station. This is the lowest hanging fruit and could be accomplished by eliminating the parking there (there are lots to the rear and south), keeping a drop off zone for passengers and building a pull out for the buses. The stopped bus creates tremendous jams along that area, especially during rush hour. • Consider eliminating the light at Market Street. Make this a right turn only intersection. Yes, this create some inconvenience, but the benefits outweigh the inconvenience. Residents can go south on Pine to exit to the East. Downtown Newhall visitors can go up to Lyons to turn left. Removing this stop will do much to keep traffic flowing. A pedestrian bridge could be built. • The most effective move, but costly, would be to build an overpass directing all Newhall Ave traffic over the intersection and then down to the roundabout. This would eliminate any stops, other than train crossings, for the Railroad to Newhall traffic and keep that flowing. If the Dockweiler extension was not done, this would result in tremendous savings and these funds could be used for the overpass. Lyons Avenue/Dockweiler Drive Extension Project Final EIR 3. Responses to Comments State Clearinghouse No. 2013082016 Page 3-90 City of Santa Clarita February 2018 • There are likely other ways to smooth traffic through Downtown but that should be a priority. TARGET TWO: This would be to find an effective bypass route to pull traffic through the area and also accommodate the increased traffic connected to the planned development along Railroad (vacant land to the west of Placerita Canyon). The ideal here would be to find a less expensive route, to find a more effective route and to find a route that has a lessened negative impact on points mentioned earlier (such as wildlife, scenic views, neighborhood disruption, etc.). In addition, finding a route that could potentially provide traffic flow benefits above and beyond what was sought would be ideal. The goal should not be "to build an extension" but to smoothly move traffic, and projected traffic increases, along the Sierra/Newhall—Santa Clarita Railroad Avenue path. The most effective solution would be to have a direct route between Sierra/Newhall and beyond the Downtown Newhall zone. Ideally this direct route would have a minimum of stops or intersections —an express way or bypass route. With the future planned development along the east side of Railroad as well as the future planned connection of Via Princessa across the valley then this route should ideally facilitate flow through the future development and also connect to the Via Princessa route. The proposed route, given of course in simple terms, would avoid the Dockweiler path completely. It would follow flat land for the most part by building along the edge of the creek bed at the base of the hill which is largely flat land. This would keep the bypass route away from any new railroad crossings and out of most all neighborhoods. There are several vacant lots along Newhall Ave where this route could connect and if built properly this route could flow into and out of Newhall without any stop signs or lights. (This would require one overpass and would only allow for traffic in the most probable and heavily used directions) The route would direct traffic into a properly sized roundabout (large enough to accommodate fire trucks and horse trailers) at the Placerita Canyon intersection. This roundabout would be well to the east of the tracks and the current stoplight, to avoid backups in that tight sector). The route would continue on into the new development and then connect into the Via Princessa future route. There are some engineering issues, such as the need to move significant dirt as the route would pass to the east of the Metro station as well as the need for one -to -three overpasses and potentially a bridge —but all of these are doable and are significantly less expensive than connecting to Dockweiler. The most significant plus is that this route would allow for greatly increased traffic flow and speed through the area, and would provide access to the Masters College and the newly developed area. It would provide safer and increased emergency exit from Placerita, minimize neighborhood disruption and loss of quality of life, it would preserve a valuable piece of open space and scenic ridgelines. Ideally that saved open space could be connected to existing open spaces and further improve the area's appeal Lyons Avenue/Dockweiler Drive Extension Project Final EIR 3. Responses to Comments State Clearinghouse No. 2013082016 Page 3-91 City of Santa Clarita February 2018 and outdoor access. With added trails for hikers and horses, and even an extension of our biking paths, this plus would help gain community support for the project as a whole. Please see attached map for a general outline of the proposed alternative. RESPONSE TO COMMENT 34.12 With respect to the commenter's suggestions for alternatives to the Proposed Project, as noted in the DEIR, the proposed connection and extension of Lyons Avenue to Dockweiler Drive is identified in the Circulation Element of the City's General Plan as one of the primary east -west arterials through the City of Santa Clarita that would provide a through connection from Sierra Highway to Railroad Avenue. The purpose of the EIR is to analyze the environmental impacts that would result from the construction and operation of the Proposed Project and analyze alternatives to the Proposed Project that may be effective in reducing or avoiding environmental impacts. Pursuant to Section 15126.6(c) of the CEQA Guidelines, "the range of potential alternatives to the proposed project shall include those that could feasibly accomplish most of the basic objectives of the project and could avoid or substantially lessen one or more of the significant effects. Among the factors that may be used to eliminate alternatives from detailed consideration in an EIR are:(i) failure to meet most of the basic project objectives, (ii) infeasibility, or (iii) inability to avoid significant environmental impacts." CEQA Guidelines Section 15126.6(b) states that "the discussion of alternatives shall focus on alternatives to the project or its location which are capable of avoiding or substantially lessening any significant effects of the project, even if these alternatives would impede to some degree the attainment of the project objectives, or would be more costly." Thus, the consideration of feasible alternatives was focused on lessening or avoiding the Proposed Project's significant and unavoidable impacts associated with air quality and construction noise and vibration. The alternative that the commenter is suggesting would not support the objectives of the Proposed Project, which include, primarily, the extension of Dockweiler Drive as identified in the General Plan. Objectives of the Proposed Project are discussed in Section 2 Project Description (see page 2-28), of the DEIR, and are also listed above in Response to Comment 20.2. Additionally, the alternative proposed by the commenter would have a larger footprint along Newhall Creek and require more grading and infrastructure improvements, as compared to the Proposed Project or the Alternative 2 Project, and therefore would result in increased adverse impacts. The commenter provides no substantial evidence to indicate that the suggested alternative would substantially lessen one or more of the significant effects as identified DEIR. The commenter's opinions regarding project alternatives have been included in the record and will be forwarded to the decision makers for their consideration. No further analysis is warranted with respect to the DEIR. COMMENT 34.13 In closing, while one has always to deal with the NIMBY factor on any development project, the proposed Dockweiler extension lacks the benefits to justify its construction. It is flawed in many ways, Lyons Avenue/Dockweiler Drive Extension Project Final EIR 3. Responses to Comments State Clearinghouse No. 2013082016 Page 3-92 City of Santa Clarita February 2018 but most importantly in that it does not begin to address the projected traffic problems and will in fact lead to increased traffic congestion. If the traffic flow needs to be resolved then this extension needs to be sidelined while alternative plans and routes that actually solve the problem are explored. This is a proposed alternative that would solve the problem. Of course, I have not done feasibility or engineering studies, but this general scope is worth discussion and review. RESPONSE TO COMMENT 34.13 The commenter's opinions regarding project alternatives have been included in the record and will be forwarded to the decision makers for their consideration. No further analysis is warranted with respect to the DEIR. COMMENT LETTER No. 35 Linda Tarnoff Date: October 16, 2017 COMMENT 35.1 Unless you can convince me otherwise, I am opposed to the Dockweiler extension unless to just the proposed Masters University expansion project. In other words, I support the No Project alternative. The additional traffic proposed to be routed through our rural equestrian neighborhood would without a doubt jeopardize our community which is already anticipating impacts from the proposed new residential construction at 13a' Street. As the Santa Clarita Valley gets built out, obviously there will be a need for additional roads. The success of Golden Valley Road is a prime example. But shunting traffic to an otherwise quiet community is not the solution. RESPONSE TO COMMENT 35.1 With respect to the Proposed Project's consistency with PCSSD, please refer to Response to Comment 12.3 above. The commenter's opinion has been included in the record and will be forwarded to the decision makers for their consideration. No further analysis is required. COMMENT 35.2 Each proposal referenced in the EIR is controversial and not without issues. Market Street is next to an active train station with high numbers of pedestrian traffic especially at peak travel times. No doubt this option is opposed by adjacent residents. Lyons Avenue would be the best scenario as a straight shot across if traveling east on Lyons but appears to have too many construction challenges i.e. need for elevation of existing road to traverse over train tracks and bridge construction over creek. 13a' Street, though easiest for the planners is problematic for Placerita Canyon. Lyons Avenue/Dockweiler Drive Extension Project Final EIR 3. Responses to Comments State Clearinghouse No. 2013082016 Page 3-93 City of Santa Clarita February 2018 RESPONSE TO COMMENT 35.2 The commenter's opinions regarding the Project alternatives has been included in the record and will be forwarded to the decision maker's for their consideration. The commenter does not raise specific concerns with respect to the environmental analysis as presented in the DEIR. No further analysis is warrented. COMMENT 35.3 In addition, at this time-- with the cleanup of Whitaker Bermite on the horizon for 2018 -- it would make sense to initiate the EIR process for the ultimate extension of Via Princessa through to Golden Valley Road. Regardless of which route the city ultimately chooses, the left turn queues will undoubtedly create lengthy back ups jutting into left lanes of traffic as demonstrated by the frequent half mile or more long left turn lanes on Sierra Highway to Golden Valley Road. Just imagine the scenario at a left turn lane from Railroad to Market Street if the road is extended there, on a curve no less. In fact, the left turn lane at 13th Street cannot accommodate traffic as it is at peak times. Change is inevitable but clearly think this one out from the impact [sic] on the local impacted communities whether it be Placerita Canyon, East Newhall or Dockweiler. RESPONSE TO COMMENT 35.3 The commenter's opinion regarding Via Princessa has been included in the record and will be forwarded to the decision maker's for their consideration. The commenter does not raise specific concerns with respect to the environmental analysis as presented in the DEIR. No further analysis is warranted. COMMENT LETTER No. 36 Valerie Thomas Date: September 14, 2017 COMMENT 36.1 Deficiency in dealing with NOP concerns: In the City's summation to concerns raised at the NOP meeting, no concerns are listed relating to greenhouse gases in concerns that I raised. [sic] In the section on Air Quality, I refer to the Global Warming Solutions Act of 2006 (AB 32). This act mandates statewide greenhouse gas emissions must be reduced to 1990 levels by 2020. SB 32, passed in 2016 and signed into law (before this draft EIR was released) expands that mandate to reduce greenhouse gas emissions 40 percent below 1990 levels by 2030. Both are state laws but this report makes no effort to deal with how additional congestion can be dealt with to comply with state law. RESPONSE TO COMMENT 36.1 Overall, the Proposed Project would reduce traffic congestion on local roadways. Thus, the Proposed Project would not result an increase in emissions. Nonetheless, with respect to the AB 32, Global Lyons Avenue/Dockweiler Drive Extension Project Final EIR 3. Responses to Comments State Clearinghouse No. 2013082016 Page 3-94 City of Santa Clarita February 2018 Warming Solutions Act of 2006, the City of Santa Clarita adopted a Climate Action Plan (CAP), which provides policies and identifies actions intended to reduce GHG emissions within the City and assist in the fight against climate change. Overall the goal of the CAP is to reduce Santa Clarita's community -wide GHG emissions below the 2005 baseline emissions by 2020. Implementation of the strategies identified in the CAP would also exceed the City's goal to reduce 2020 GHG emissions to a level below the 2005 GHG emissions baseline by 4 percent. COMMENT 36.2 LOS: PCPOA met with City staff on July 25 for a presentation on the Draft EIR. We were assured LOS levels A-F did not correspond to scholastic letter grades. The Evans Report (page 13) states "The LOS ranges from `A" [sic] (the best) through `F" [sic] (system breakdown)." That's very similar to scholastic grades. RESPONSE TO COMMENT 36.2 There is no correlation between scholastic grades and the level -of -service ("LOS"). The definition for LOS can be found in Section 4.9 on page 4.9-6 of the DEIR. LOS quantitatively describes the operating characteristics of signalized intersections and the maximum delay. The level -of -service is based on the average delay of vehicles at the intersections. Table 4.9-1 provides the LOS thresholds for signalized intersections per the HCM 2010 methodology. No further response is required. COMMENT 36.3 Ongoing transportation issues: • The report posits Lyons as a three -lane avenue. While some of Lyons is three -lanes, the portion from Orchard Village to Railroad allows street parking. Merchants have long fought allowing three lanes since there is inadequate off street parking. OLPH submitted a Master Plan several years ago outlining their proposed expansion; that plan was withdrawn allowing piecemeal expansion. RESPONSE TO COMMENT 36.3 The portion of Lyons Avenue from Walnut Street to Railroad Avenue provides three lanes of travel in each direction with no on -street parking. This comment has been noted for the record, no further response is required. COMMENT 36.4 • The transportation section proposes two left turn lanes, one right turn lane and one straight ahead lane at Lyons where it meets Railroad; where is this additional lane coming from? What provisions are made at this intersection for the traffic from the substantial under -construction parking structure? Or the Laemmle Theater? Lyons Avenue/Dockweiler Drive Extension Project Final EIR 3. Responses to Comments State Clearinghouse No. 2013082016 Page 3-95 City of Santa Clarita February 2018 RESPONSE TO COMMENT 36.4 As discussed above in Response to Comment 36.3, the portion of Lyons Avenue from Walnut Street to Railroad Avenue provides three lanes of travel in each direction with no on -street parking. As shown in Figure 2-17 Lyons Avenue Street Widening - Proposed New Crossing, of the DEIR, the intersection improvements will include widening the northbound direction to accommodate an additional left turn lane and convert a through lane to a shared through -right lane and southbound direction to accommodate an additional left turn lane and convert the right turn lane to a shared through -right turn lane. The north and southbound directions will include two left turn lanes, a through lane, and a shared through -right turn lane. The eastbound direction will provide a left turn lane, a through lane, and a shared through -right turn lane. The westbound direction will provide a left turn lane, two through lanes and a right turn lane. Traffic improvements consider the additional build out of the General Plan as further discussed in Section 4.9, Transportation and Traffic, of the DEIR. No further response is required. COMMENT 36.5 • Peak hour numbers do not allow for Metro train traffic. Please adjust the report. RESPONSE TO COMMENT 36.5 Traffic counts were compiled for the existing railroad crossings at 13a' Street, Market Street, and Newhall Avenue. A.M. and P.M. peak hour traffic counts included the existing vehicles, pedestrians, and bicycle volumes. Refer to Tables 4.9-8 through 4.9-10 on pages 4.9-30 and 4.9-31, respectively, of the DEIR. No further analysis is required. COMMENT 36.6 • How does the closer proximity to Newhall Metro station affect crossing safety/timing at this intersection? RESPONSE TO COMMENT 36.6 The Proposed Project would include a new at -grade crossing at the proposed extension of Lyons Avenue from Railroad Avenue. The Proposed Project would include the closure of the existing at -grade crossing at 13a' Street and Railroad Avenue. The new crossing would be located approximately 0.25 mile north of the existing at -grade crossing located at Market Street. Similar to existing conditions, the Proposed Project would not provide access between Dockweiler Drive to Market Street. Therefore, in the event that railroad gates are in a down position at the new crossing at Lyons Avenue, when a train is stopped at the Metrolink station to the south, the traffic on Market Street would remain unaffected by the new at -grade crossing. Under the Alternative 2 Project, the 13a' Street at -grade crossing would remain and no at -grade crossing would occur at Lyons Avenue and Railroad Avenue. As such, future conditions would be similar to existing conditions at 13a' Street under the Alternative 2 Project. Further, the Proposed Project and Alternative 2 Project are subject to SCRRA approval, and as such, the Proposed Project and Alternative 2 Project would comply with all applicable operational rail crossing safety improvements with respect to Lyons Avenue/Dockweiler Drive Extension Project Final EIR 3. Responses to Comments State Clearinghouse No. 2013082016 Page 3-96 City of Santa Clarita February 2018 control point locations, crossing signals and gates to minimize disruptions to both vehicular, pedestrian and train circulation. No further analysis of this issue is warranted at this time. COMMENT 36.7 • What provisions are made for circulation during construction? Nighttime construction is not an answer with a road being raised six feet or more. (The City is already in a mess with three major construction projects: Railroad, Orchard Village and McBean.) [sic] Simply posting signs "Use alternate routes" is not sufficient, particularly when the City has made no effort to adjust the timing of the affected signals. How will traffic get to Lyons from either direction? RESPONSE TO COMMENT 36.7 As discussed in Response to Comment 6.3, in response to LASD's concerns regarding construction, the Proposed Project will require a Construction Management Plan, which shall be submitted to the City of Santa Clarita Public Works Department (Traffic and Transportation Division) and LASD Santa Clarita Valley Station for review and approval prior to the commencement of any construction. The plans shall show the location of any roadway or sidewalk closures, traffic detours, haul routes, hours of operation, protective devices, warning signs and access to abutting properties, and if applicable, the location of off - site staging areas for haul trucks and construction vehicles, and provide one or more emergency lane through the Project site at all times. See Section 2, Additions and Corrections; and Section 4, Mitigation Monitoring Program. No further response sis required. COMMENT 36.8 • Dockweiler parking: The EIR shows Dockweiler as two lanes in each direction. Much of the road by the condos and apartments has been used for years as supplemental parking. What provisions are being made for these vehicles? Many of the units are within 10 feet of the existing roadway; how will the quality of life for these residents (safety, noise, pollution) be maintained? RESPONSE TO COMMENT 36.8 The existing portion of Dockweiler Drive, referenced by the commenter, is outside the project limits of the Proposed Project. Nonetheless, the construction of Tract No. 32365 in which the commenter is referring to includes the construction of Dockweiler Drive as a secondary highway with a 73-foot right- of-way. While Dockweiler Drive currently terminates at the western limits of Tract No. 32365, it was designed to continue westward as a major roadway consistent with the City's Circulation Element. As noted in the City's Circulation Element, in order to accommodate future traffic volumes, the portion of Dockweiler Drive between Leonard Tree Lane and Sierra Highway would be re -striped from two lanes to four lanes. It is not anticipated that traffic volumes would increase such that re -striping would be necessary; however, should re -striping to four lanes be necessary, notification and public outreach will be conducted prior to re -striping.

Responses to Comments State Clearinghouse No. 2013082016 Page 3-97 City of Santa Clarita February 2018 This comment will be included in the record and forwarded to the decision makers for their consideration. No further analysis with respect to the environmental analysis for the DEIR is required. COMMENT 36.9 • If federal funds are sought for any portion of this construction, does that mean the City will have to allow heavy traffic on Dockweiler? What safety provisions will be made for locals to protect them from trucks barreling down that grade? RESPONSE TO COMMENT 36.9 The Proposed Project would be designed in accordance with the appropriate design features and safety standards (such as speed limits, light signals and striping) required for secondary highways and railroad crossings and would be subject to the site plan review requirements of the City of Santa Clarita. No further analysis is required. COMMENT 36.10 • Roundabout not safe or adequate for truck traffic or horse trailers. RESPONSE TO COMMENT 36.10 In the event "Option B, as identified in the DEIR (See Figure 2-12) is selected, the traffic circle would be designed in accordance with the appropriate design features and standards and would be subject to the site plan review requirements of the City of Santa Clarita. No further analysis is required. COMMENT 36.11 Think outside the Box 1. Take Traffic up to Circle J. Nice to keep your promises to them, but Placerita has promises written into the General Plan and our Special Standards District to protect our rural equestrian way of life. No part of this proposal is compatible with a rural equestrian lifestyle. RESPONSE TO COMMENT 36.11 As analyzed in Section 4.7, Table 4.7-3, page 4.7-18, of the DEIR, the Proposed Project is in substantial compliance with the standards identified in the PCSSD. The proposed connection of Lyons Avenue to Dockweiler Drive would not conflict with or alter any equestrian facilities or trails. To the contrary, the Proposed Project would increase access in the PCSSD, as the proposed alignment of Dockweiler Drive would include a Class II Bike Route and pedestrian walkways on the east side. Lyons Avenue/Dockweiler Drive Extension Project Final EIR 3. Responses to Comments State Clearinghouse No. 2013082016 Page 3-98 City of Santa Clarita February 2018 COMMENT 36.12 2. Flyover at 15th Street. RESPONSE TO COMMENT 36.12 As noted in the DEIR, the proposed connection and extension of Lyons Avenue to Dockweiler Drive is identified in the Circulation Element of the City's General Plan as one of the primary east -west arterials through the City of Santa Clarita that would provide a through connection from Sierra Highway to Railroad Avenue. The purpose of the EIR is to analyze the environmental impacts that would result from the construction and operation of the Proposed Project and analyze alternatives to the Proposed Project that may be effective in reducing or avoiding environmental impacts Pursuant to Section 15126.6(c) of the CEQA Guidelines, "the range of potential alternatives to the proposed project shall include those that could feasibly accomplish most of the basic objectives of the project and could avoid or substantially lessen one or more of the significant effects. Among the factors that may be used to eliminate alternatives from detailed consideration in an EIR are:(i) failure to meet most of the basic project objectives, (ii) infeasibility, or (iii) inability to avoid significant environmental impacts." The commenter does not provide substantial evidence to support the rationale of a flyover at 15th Street as a viable alternative. To the contrary, a flyover at this intersection would not support the objectives of the Proposed Project, which include, primarily, the extension of Dockweiler Drive as identified in the General Plan. Objectives of the Proposed Project are discussed in Section 2 Project Description (see page 2-28), of the DEIR, and are also listed above in Response to Comment 20.2. No further response is required. COMMENT 36.13 3. Bring Dockweiler to Pine Street. Extend to Market and then down to Pine across Newhall Avenue where it goes to NCWD. That avoids trains tracks altogether. RESPONSE TO COMMENT 36.13 As disclosed in the DEIR in Section 6.1, the Market Street Alternative was rejected from further consideration due to the physical constraints associated with grading, as well as the Alternative's incompatibility with respect to public safety and local residential street standards (See Section 6.1, page 6.1-2). Specifically, this alternative was rejected from further consideration due to the resulting 11.15% gradient of the roadway profile resulting from the existing topographical gradient between Market Street and Dockweiler Drive, the relatively sharp curve at the base of an include where the alignment would connect to Market Street. A gradient of 11.15% would not meet the street standards of a secondary highway and would potentially result in unsafe roadway conditions. Additionally, Market Street is a local residential street that directly abuts and provides access to single and multi -family residential land uses. The proposed alignment of Dockweiler Drive through this existing residential neighborhood would not be Lyons Avenue/Dockweiler Drive Extension Project Final EIR 3. Responses to Comments State Clearinghouse No. 2013082016 Page 3-99 City of Santa Clarita February 2018 consistent with the alignment identified within the Circulation Element and would not be compatible with respect to public safety and local residential street standards. For this reason, this alternative alignment was rejected as infeasible. See also Response to Comment 12.38, above, and Section 2. Additions and Corrections, Market Street Alignment Additional Analysis. The commenter's opinion has been noted for the record and will be forwarded to the decision makers for their consideration. No further response is required. COMMENT 36.14 Need more examination of 13t'' Street RESPONSE TO COMMENT 36.14 The commenter does not specify in what context 13th Street needs further examination. Impacts to 13th Street under the Proposed Project and three project alternatives is thoroughly analyzed in the DEIR. No further analysis is warranted. COMMENT 36.15 Flooding RESPONSE TO COMMENT 36.15 The commenter does not provide context with respect to this comment. Nonetheless, as discussed in detail in Section 4.6 Hydrology and Water Quality, a post -Project hydraulic model was analyzed to determine the impacts of inundation and flooding (See Hydraulic and Scour Analysis Newhall Creek at Proposed Dockweiler Road Bridge, Newhall, California, prepared by Rivertech, Inc., dated February 2015 ("Hydraulic Report"), (See Appendix G of the DEIR). Refer also to Response to Comment 12.9. No further response is required.

COMMENT LETTER No. 37 Robert and Teresa Todd Date: October 16, 2017 COMMENT 37.1 1. Regarding the traffic study in the Draft EIR, Dockweiler is a Secondary Highway connecting with Placerita Canyon. Highways and horses do not mix, so this alignment has the potential to negate the rural equestrian lifestyle and/or violate the Special Standards District previously established. RESPONSE TO COMMENT 37.1 As analyzed in Section 4.7, Table 4.7-3, page 4.7-18, of the DEIR, the Proposed Project is in substantial compliance with the standards identified in the PCSSD. The proposed connection of Lyons Avenue to Dockweiler Drive would not conflict with or alter any equestrian facilities or trails. To the contrary, the Proposed Project would increase access in the PCSSD, as the proposed alignment of Dockweiler Drive would include a Class II Bike Route and pedestrian walkways. COMMENT 37.2 2. Dockweiler to 13a' St. creates a bypass artery that avoids Downtown Newhall contrary to the economic development objective of the area (traffic study indicates a 31% decrease in Lyons traffic from 2019 to 2035 if Alternative #2 goes forward). RESPONSE TO COMMENT 37.2 As discussed in Section 6, Project Alternatives, of the DEIR, under the Alternative 2 Project scenario, Lyons Avenue, between Main Street and Railroad Avenue, would experience average daily traffic (ADT) of 10,400 and 14,400 vehicles for years 2019 and 2035, respectively. Under the Proposed Project scenario, Lyons Avenue, between Main Street and Railroad Avenue, would experience ADT of 12,100 and 26,600 vehicles for years 2019 and 2035, respectively. Under the No Build scenario, Lyons Avenue, between Main Street and Railroad Avenue, would experience ADT of 10,700 and 13,700 vehicles for years 2019 and 2035, respectively. Therefore, although the Alternative 2 Project results in fewer trips on this segment of Lyons Avenue when compared to the Proposed Project, the connection of Dockweiler Drive to 13a' Street would still create a new connection to Old Town Newhall that would result in generally the same amount of trips for the 2019 year and an increase in trips along this portion of Lyons Lyons Avenue/Dockweiler Drive Extension Project Final EIR 3. Responses to Comments State Clearinghouse No. 2013082016 Page 3-101 City of Santa Clarita February 2018 Avenue for the 2035 build out year when compared to the No Build scenario. No further analysis with respect to the DEIR is warranted. COMMENT 37.3 3. Dockweiler experiences a 446% increase with Lyons improvement; 272% increase with Alternative #2, yet Railroad Avenue experiences a modest 5% decrease from No Project to Alternative #2. Given the math in the traffic study, neither alternative satisfies the City's objective to reduce volume (as presented as travel time) on Newhall Avenue by nearly half. RESPONSE TO COMMENT 37.3 To clarify, the objective of the Proposed Project is not to specifically reduce traffic volume on Newhall Avenue by half, as stated by the commenter, but rather to develop a major east -west corridor, consistent with the General Plan, to facilitate access to existing and planned development, reduce "cross valley" trip lengths and travel times, provide an alternate travel route, and support a multi -modal transportation network by reducing bus travel times in the City and providing opportunities for increased bike and pedestrian traffic. The commenter does not provide enough context or information to support their methodology. Based on the Traffic Study, under the Proposed Project, the proposed portion of Dockweiler Drive from the extension of Lyons Avenue to the approved connection at The Master's College would experience ADT of 3,900 and 18,300 vehicles for the 2019 and 2035 years, respectively. Under the Alternative 2 Project, the proposed portion of Dockweiler Drive between 12a' Street and The Master's College would experience ADT of 3,400 and 7,800 vehicles for years 2019 and 2035, respectively. Therefore, under the Proposed Project the proposed extension of Dockweiler Drive would experience approximately 15% and 140% more ADT as compared to the Alternative 2 Project for years 2019 and 2035, respectively. With respect to Railroad Avenue, the portion of Railroad Avenue between Lyons Avenue and 13a' Street would experience ADT of 34,700 vehicles for the No Build Scenario for build out year 2035. Under the Alternative 2 Project, the portion of Railroad Avenue between 13a' Street and Lyons Avenue would experience ADT of 30,100 vehicles for buildout year 2035. Therefore, this portion of Railroad Avenue would experience approximately 13% less ADT under the Alternative 2 Project as compared to the No Project scenario. No further analysis with respect to the DEIR is warranted. COMMENT 37.4 4. TMU has a dramatic increase in traffic load with the Lyons crossing, yet with No Project and Alternative #2 that load decreases by 10-13,000 vehicles. Question is where did those vehicles go? The traffic counts on Dockweiler and 13a' do not make up for the variances in the data. The validity of the Alternative #2 traffic load is questionable given the unexplained variances. Lyons Avenue/Dockweiler Drive Extension Project Final EIR 3. Responses to Comments State Clearinghouse No. 2013082016 Page 3-102 City of Santa Clarita February 2018 RESPONSE TO COMMENT 36.4 As shown in the Traffic Study to the DEIR, the portion of Dockweiler Drive between The Master's College and Valle Del Oro would experience ADT of 4,300, 17,300 and 7,400 vehicles for the No Build, Proposed Project and Alternative 2 Project, respectively for the 2035 build out year. The decrease in vehicles utilizing this portion of Dockweiler Drive for the No Project and the Alternative 2 Project is the result of maintaining the existing intersection at 13th Street and Railroad Avenue. The Proposed Project would include the closure of this intersection. The portion of 13th Street between Railroad Avenue and Arch Street would experience ADT of 16,900, 0 (zero) and 17,700 vehicles for the No Build, Proposed Project and Alternative 2 Project, respectively for the 2035 build out year. The commenter's assertions with respect to the traffic analysis are unsubstantiated. No further analysis with respect to the DEIR is warranted. COMMENT 37.5 5. Safety is a key consideration at an active rail crossing with on average 38 trains per weekday (8 freight and 30 commuter). Alternative #2 has a 92% increase in traffic between 2019 and 2035, which amplifies the risk of rail -related incidents. RESPONSE TO COMMENT 37.5 It is unclear how the commenter is arriving at the conclusion that the Alternative 2 project results in a 92% increase in traffic between 2019 and 2035. The commenter does not provide enough context or information to support their methodology. Based on the Traffic Study, under the Alternative 2 Project, as shown in Table 6.4-3 and 6.4-4 on page 6.4-28 of the DEIR, the ADT for all three railroad crossings would be 56,420 and 76,790 vehicles for year 2019 and buildout year 2035, respectively. Therefore, under the Alternative 2 Project the ADT for all three crossings would increase by approximately 36% between 2019 and 2035. With respect to safety the Proposed Project is subject to CPSCRRA approval and as such the Proposed Project would comply with all applicable construction -related and operational rail crossing safety requirements, including those listed Section 2, Project Description of the DEIR. Refer also to Response to Comment 3.2, above. This comment has been noted for the record and will be forwarded to the decision makers for their consideration. No further response is required. COMMENT LETTER No. 38 Pat Willett September 14, 2017 COMMENT 38.1 Traffic: I'm concerned about emergency access in and out of the canyon with all the additional traffic at the 13th St. crossing. Lyons Avenue/Dockweiler Drive Extension Project Final EIR 3. Responses to Comments State Clearinghouse No. 2013082016 Page 3-103 City of Santa Clarita February 2018 RESPONSE TO COMMENT 38.1 As discussed in Section 5.1 Impacts Determined to be Less Than Significant, page 5.1-3, subheading Fire and Police Protection, of the DEIR, emergency access to the Placerita Canyon community would be facilitated through the Project's alignment, which is consistent with the City's adopted Circulation Element. The Project's alignment would be an improvement to the current access route into the Placerita Canyon community via 13a' Street. As stated in Comment Letter No. 5, the Los Angeles County Sheriffs Station generally supports public improvements similar to that of the Proposed Project because these improvements typically result in an overall positive impact upon law enforcement patrol operations, emergency access, and response times. (See Comment Letter No. 5, above). No further analysis is warranted. COMMENT 38.2 What is stopping us from adding a Lyons/Dockweiler crossing and simply keeping or improving the 13a' St crossing? RESPONSE TO COMMENT 38.2 This alternative was identified in the DEIR as the Alternative 1 Project (see Section 6.3-1 of the DEIR). The Alternative 1 Project would involve the development of the proposed roadway alignment and associated infrastructure, which would include a new at -grade crossing and a secondary east -west arterial roadway connecting Lyons Avenue to the proposed Dockweiler Drive extension that would connect Dockweiler Drive to a new five -leg intersection at the Arch Street/12a' Street/Placerita Canyon intersection. The Alternative 1 Project would leave the existing at -grade crossing at the intersection of 13a' Street and Railroad Avenue as is instead of removing the crossing, as proposed by the Proposed Project. The proposed alignment of Dockweiler Drive under Alternative 1 is illustrated in Figure 6.3-1 of the DEIR. The commenter's opinion will be forwarded to the decision makers for their consideration. No further analysis is required. COMMENT LETTER No. 39 Jong Yoon Date: October 23, 2017 COMMENT 39.1 I am out of country until at the end of November.

My house sits on Placerita Canyon, close to Arch St. I do not see how bringing unnecessary traffic onto our rural streets will in any way improve our neighborhood. When the residents of Happy Valley complained to the city about excessive traffic on Valley St due to the gate at Calgrove being available to the Hidden Valley residents via a gate card, the city SHUT down a road that was on the master plan as a public road. So to tell us the Arch St-Dockweiler expansion "has" to be done because it is on the master plan is false. The ONLY person who wants this road is oddly a City Council member with property that might be of value to the city. Makes one wonder who the City is "serving" Certainly NOT the vast majority of Placerita canyon residents. We would prefer the third option; DO NOTHING. Perhaps the City should finally expand Via Pricessa [sic]. That's been promised for years and would actually improve traffic flow in Santa Clarita RESPONSE TO COMMENT 42.1 This comment letter has been included in the record and will be forwarded to the decision makers for their consideration.

INTRODUCTION Section 21081.6 of the Public Resources Code requires a Lead Agency to adopt a "reporting or monitoring program for the changes made to the project or conditions of project approval, adopted in order to mitigate or avoid significant effects on the environment" (Mitigation Monitoring Program, Section 15097 of the CEQA Guidelines provides additional direction on mitigation monitoring or reporting). This Mitigation Monitoring and Reporting Program (MMP) has been prepared in compliance with the requirements of CEQA, Public Resources Code Section 21081.6, and Section 15097 of the CEQA Guidelines. The City of Santa Clarita is the Lead Agency for this project. An Environmental Impact Report (EIR) has been prepared to address the potential environmental impacts of the Lyons Avenue/Dockweiler Drive Extension Project (Proposed Project). Where appropriate, this environmental document identified the Proposed Project's design features, regulatory compliance measures, or recommended mitigation measures to avoid or to reduce potentially significant environmental impacts of the Proposed Project. This MMP is designed to monitor implementation of the mitigation measures identified for the Proposed Project. The MMP is subject to review and approval by the City of Santa Clarita as the Lead Agency as part of the approval process of the Proposed Project, and adoption of project conditions. The required mitigation measures are listed and categorized by impact area, as identified in the EIR. The City of Santa Clarita shall be responsible for implementing all mitigation measures, unless otherwise noted, and shall be obligated to provide documentation concerning implementation of the listed mitigation measures to the appropriate monitoring agency and the appropriate enforcement agency as provided for herein. All departments listed below are within the City of Santa Clarita unless otherwise noted. The entity responsible for the implementation of all mitigation measures shall be the City of Santa Clarita unless otherwise noted. The City shall maintain records demonstrating compliance with each project feature and mitigation measure. Such records shall be made available to the City upon request. As shown on the following pages, each required mitigation measure for the Proposed Project is listed and categorized by impact area, with accompanying discussion of: Enforcement Agency: the agency with the power to enforce the mitigation measure. Monitoring Agency: the agency to which reports involving feasibility, compliance, implementation and development are made, or whom physically monitors the project for compliance with mitigation measures. Monitoring Phase: the phase of the project during which the mitigation measure shall be monitored. Monitoring Frequency: the frequency of which the mitigation measure shall be monitored.

Mitigation Monitoring Program State Clearinghouse No. 2013082016 Page 4-1 City of Santa Clarita February 2018 Action Indicating Compliance: the action of which the Enforcement or Monitoring Agency indicates that compliance with the required mitigation measure has been implemented. The MMP performance shall be monitored annually to determine the effectiveness of the measures implemented in any given year and reevaluate the mitigation needs for the upcoming year. It is the intent of this MMP to: • Verify compliance of the required mitigation measures of the EIR; • Provide a methodology to document implementation of required mitigation; • Provide a record and status of mitigation requirements; • Identify monitoring and enforcement agencies; • Establish and clarify administrative procedures for the clearance of mitigation measures; • Establish the frequency and duration of monitoring and reporting; and • Utilize the existing agency review processes' wherever feasible. • This MMP shall be in place throughout all phases of the Proposed Project. The entity responsible for implementing each mitigation measure is set forth within the text of the mitigation measure. The entity responsible for implementing the mitigation shall also be obligated to provide certification, as identified below, to the appropriate monitoring agency and the appropriate enforcement agency that compliance with the required mitigation measure has been implemented. After review and approval of the final MMP by the Lead Agency, minor changes and modifications to the MMP are permitted, but can only be made subject to the approval by the City of Santa Clarita through a public hearing. The Lead Agency, in conjunction with any appropriate agencies or departments, will determine the adequacy of any proposed change or modification. The flexibility is necessary in light of the proto-typical nature of the MMP, and the need to protect the environment with a workable program. No changes will be permitted unless the MMP continues to satisfy the requirements of CEQA, as determined by the Lead Agency. B. MITIGATION MONITORING PROGRAM The organization of the MMP follows the subsection formatting style as presented within the EIR. Subsections of all of the environmental chapters presented in the EIR are provided below. For environmental issue areas where no mitigation measures were required, the MMP is noted accordingly.

Mitigation Monitoring Program State Clearinghouse No. 2013082016 Page 4-5 City of Santa Clarita February 2018 species, the applicant shall have a qualified biologist conduct surveys for active nests. The project management shall endeavor to avoid the breeding season. In the event it is not feasible to avoid the nesting season, a qualified biologist shall perform weekly nesting bird surveys beginning 30 days prior to initiation of ground -disturbing activities, with the last survey conducted no more than three days prior to the start of clearance/construction work. If ground - disturbing activities are delayed, additional preconstruction surveys shall be conducted so that no more than three days have elapsed between the survey and ground -disturbing activities. Surveys shall include examination of natural habitat for nesting birds. Several bird species such as killdeer and night hawks are known to nest on bare ground. Protected bird nests that are found within the construction zone shall be protected by a buffer deemed suitable by a qualified biologist, and verified by CDFW. Typically, a 300-foot buffer is required for most species and a 500-foot buffer for raptor species. Buffer areas shall be delineated with orange construction fencing or other exclusionary material that would inhibit access within the buffer zone. Installation of the exclusionary material delineating the buffer zone shall be verified by a qualified biologist prior to initiation of construction activities. The buffer zone shall remain intact and maintained while the nest is active (i.e., occupied or being constructed by the adults bird(s)) and until young birds have fledged and no continued use of the nest is observed, as determined by a qualified biologist. 4.3-3 Prior to project construction, the following is California California Pre -construction Once, at plan Issuance of grading required to mitigate impacts to jurisdictional Department of Department of check permit resources: Fish and Fish and a. Areas of impact proposed by the project shall be Wildlife and Wildlife and calculated and permits for these proposed I Community Community Lyons Avenue/Dockweiler Drive Extension Project Final FIR 4. Mitigation Monitoring Program State Clearinghouse No. 2013082016 Page 4-6 City of Santa Clarita February 2018 impacts shall be obtained (the discharge of fill Development Development into ACOE jurisdictional areas will require a Department Department permit pursuant to Section 404 of the Clean (Planning (Planning Water Act and a 401 Certification from the State Division) Division) Water Resources Control Board, and any modification to a streambed, [analysis states none is present], will require a streambed alteration agreement from CDFW pursuant to Section 1600 of the California Fish and Game Code). Both the streambed alteration agreement and the 401 and 404 permits will required specific mitigations for any impacts within their respective jurisdictions. b. Because the proposed bridge is a `span' design, it does not require footings within the bed of the stream. However, plan designs do include approximately 450 feet of bank stabilization on both sides of the stream that would lie within CDFW, ACOE and Regional Water Quality Control Board jurisdiction. Since little vegetation exists within this drainage, it is uncertain what mitigation these regulatory agencies may require. c. The stream in the impacted area would not be conductive to re -vegetation as the area of the project is deeply incised with little existing vegetation and newly planted vegetation would likely be washed away with the next storm event. d. Mitigation can be completed off site. Because there is essentially no riparian vegetation being removed with implementation of this project, revegetation off site, in a location approved by the City and CDFW, would be accomplished at a 1:1 area ratio. e. Upon City and agency approval of a suitable location, a detailed restoration plan shall be prepared that provides a planting palette, planting methods, and irrigation plan (as appropriate). The plan will also include a 5-year monitoring effort to ensure success of the restoration effort. The monitoring plan will Lyons Avenue/Dockweiler Drive Extension Project Final EIR 4. Mitigation Monitoring Program State Clearinghouse No. 2013082016 Page 4-7 City of Santa Clarita February 2018 include monitoring methods, monitoring frequency, success criteria, and contingency actions should the success criteria not be met for any reason. Annual monitoring reports shall be provided to both CDFW and the City. 4.3-4 The following guidelines shall be implemented to Community Community Pre -construction Periodic field Field inspection sign - minimize impacts on remaining biological resources Development Development and construction inspections off on the site as a result of construction and grading Department Department during activities and to ensure that potential impacts on (Planning (Planning construction these resources will remain less than significant.

Responsibilities of the construction monitor shall include the following: • Attend all pre -grading meetings to ensure that the timing and location of construction activities do not conflict with mitigation requirements. • Conduct meetings with the contractor and other key construction personnel, describing the importance of restricting work to within the project boundaries and outside of the preserved areas. The monitor shall also work with the contractor to determine the most appropriate staging/storage areas for equipment and materials. • Guide the contractor in marking/flagging the construction area limits, in accordance with the final approved grading plan. • Periodically and routinely visit the site during construction to coordinate and monitor compliance with the above provisions. The construction contractor shall install temporary erosion control measures to reduce impacts to and protect on site drainages from excess sedimentation, siltation, and erosion. Lyons Avenue/Dockweiler Drive Extension Project Final EIR 4. Mitigation Monitoring Program State Clearinghouse No. 2013082016 Page 4-8 City of Santa Clarita February 2018 These measures shall consist of minimization of existing vegetation removal; the use of temporary soil covers, such as hydro -seeding with native species, mulch/binder and erosion control blankets to protect exposed soil from wind and rain erosion; and/or the installation of silt fencing, berms, and dikes to protect storm drain inlets and drainages. No changing of oil or other fluids, or discarding of any trash or other construction waste materials shall occur on the Project Site. Vehicles carrying supplies, such as concrete, shall not be allowed to empty, clean out, or otherwise place materials into natural areas on or immediately adjacent to the site. Any equipment or vehicles driven and/or operated within or adjacent to drainages shall be checked and maintained daily, to prevent leaks of materials that if introduced to water could be deleterious to aquatic life. No equipment maintenance shall be conducted within the drainage channels or within 50 feet of channels. (Fuel -powered vehicles and equipment shall not be left idling or operated beyond periods need to accomplish approved tasks.) Construction personnel shall be prohibited from entry into areas outside the designated construction area, except for necessary construction related activities, such as surveying. All such construction activities in or adjacent to remaining open space areas shall be coordinated with the project biologist. Standard dust control measures of the South Coast Air Quality Management District shall be implemented to reduce impacts on nearby plants and wildlife. This includes a variety of options to reduce dust including replacing ground cover in disturbed areas as quickly as possible, watering active sites regularly, and suspending all excavating and grading Lyons Avenue/Dockweiler Drive Extension Project Final FIR 4.

Making Conservation a California Way of Life. Thank you for including the California Department of Transportation (Caltrans) in the environmental review process for the above referenced project. The project consists of an extension of Lyons Avenue from Railroad Avenue southeast to a proposed connection with 1.1 Dockweiler Drive, to provide a T-intersection at Dockweiler Drive. Also included are a new at - grade railro id crossing east of Railroad Avenue and Lyons Avenue as well as an extension of Docwcilcr Drive and other various modifications on 13`b Street, The nearest State facility to the project site is State Route 14. Caltrans does not expect project 1.2 approval to result in direct adverse impacts to existing State transportation facilities. Any transportation of heavy construction equipment and/or materials requiring use of oversized - transport vehicles on State highways will require a Caltrans transportation permit. Caltrans ] 1.3 recommends that large size truck trips be limited to off-peak commute periods. Also, storm water run-off is a sensitive issue for Los Angeles and Ventura counties. Be mindful that the project needs 1.4 to be designed to discharge clean run-off water.

The California Public Utilities Code requires Commission approval for the construction or alteration of crossings and grants the Commission exclusive power on the design, alteration, grade separation and closure of crossings. The Commission's Rail Crossings and Engineering Branch (RCEB) is in receipt of the Draft EIR of the Lyons Avenue/ Dockweiler Drive Extension Project. The City of Santa Clarita (City) is the lead agency. As part of the project, the City proposes to create a new at -grade highway -rail crossing of the Los Angeles County Metropolitan Transportation Authority (Metro) tracks and Lyons Avenue, and potentially upgrade or close the at -grade crossing at 13th Street, identified as CPUC crossing No. 101 VY-30.39 and DOT No. 746016J. Currently, the Southern California Regional Rail Authority (SCRRA) and the Union Pacific Railroad Company (UPRR) operate thirty passenger trains and nine freight trains over this line per day, respectively, at a maximum speed of 70 miles per hour. 3.1 Any development adjacent to or near the railroad right-of-way (ROW) should be planned with the safety of the rail corridor in mind. New developments will increase traffic volumes not only on streets and at intersections, but also at any adjacent at -grade rail crossing. Language should be in place 3.2 so that any traffic impact studies undertaken should also address rail crossing safety analysis and associated proposed mitigation measures, including grade separation. The Commission has adopted the Federal Railroad Administration's (FRA) policy to reduce the number of at -grade crossings on freight or passenger railroad mainlines in California. RCEB issued a comment letter in 2009 opposing the grade crossing alternative at Lyons Avenue and a second comment letter issued in 2015 after reviewing the City's Grade Separation Analysis with the same conclusion. While RCEB applauds the City's efforts to upgrade or close the 13th Street crossing, RCEB staff remains consistent in our position and opposes the at -grade option at Lyons Avenue due to the following reasons: • Accident history reveals grade crossings located adjacent to a parallel highway and four - legged intersections are prone to accidents; ■ Lyons Avenue will be utilized as a major local arterial between Interstate 5 Freeway and State Route 14, therefore traffic volume and roadway function are not comparable to the existing 13th Street crossing; ■ Existing railroad mainline contains heavy train traffic, with intercity commuter and freight trains operating in high speed; • The grade separation options have not been demonstrated as impracticable at this location. 3.3 Carla Callahan Page 2 of 2 August 29, 2017 If the City intends to move forward with the at -grade option, a formal application must be made to the Commission. The normal timeframe for a formal proceeding usually varies from eight (8) to twelve (12) months but can be longer if the application is contested and evidentiary hearings are held. Please be advised that based on site -specific conditions, train traffic and information provided by the City, RCEB will protest the grade crossing application.

This letter conveys recommendations from the Los Angeles County Metropolitan Transportation Authority (Metro) concerning issues that are germane to our agency's statutory responsibility in relation to our facilities and services that may be affected by the proposed project. Metro is committed to working with stakeholders across the County to support the development of transit oriented communities (TOCs). TOCs are built by considering transit within a broader community and creating vibrant, compact, walkable, and bikeable places centered around transit stations and hubs with the goal of encouraging the use of transit and other alternatives to driving. Metro looks forward to collaborating with local municipalities, developers, and other stakeholders in their land use planning and development efforts, and to find partnerships that support TOCs across 7. Los Angeles County. Project Description The Proposed Project includes: the extension of Lyons Avenue from Railroad Avenue southeast to the proposed connection with Dockweiler Drive, to provide a T-intersection at Dockweiler Drive; the addition of a new at -grade railroad crossing east of the Railroad Avenue and Lyons Avenue intersection; and the extension of Dockeweiler Drive from the approved extension a the Master's University (The Master's University extension of Dockweiler Drive through the Master's University property was approved and evaluated under a separate EIR) northwest to connect with the intersection of Arch Street and 121" Street. Metro Comments Metrolink Adjacent 7.2 It is noted that the proposed project would extend Lyons Avenue across an existing LACMTA-owned Railroad Right -of -Way (ROW). ROW is operated and maintained by the Southern California Regional Rail Authority (SCRRA) to run the Metrolink commuter rail service and Union Pacific Railroad freight The Lyons Ave/Dockweiler Drive Extension Project Notice of Availability EIR— Metro Comments October 16, 2017 trains also operate on this line. SCRRA will be providing separate comments, however, the following concerns related to the project's proximity to the ROW should be addressed in the EIR: 1. The project sponsor is advised that rail service operates in both directions and that trains may 7.2 operate, in and out of revenue service, 24 hours a day, seven days a week, in the ROW adjacent to the proposed project. 2. The policy adopted by the SCRRA Board of Director stipulates that if a new at grade crossing is 7.3 developed, one or more existing at -grade crossings in the area must be closed. 3. It should be noted that railroad crossings are under jurisdiction of the California Public Utility Commission (CPUC). The project sponsor will be required to obtain the necessary 7.4 authorization to construct the crossing. This will include demonstrating that a grade separation crossing is not practical. 4. It is likely that this proposed crossing will include the addition of warning devices, traffic signal modifications, and railroad signaling modifications. These modifications, along with the 7.5 necessary use of train horns will bring additional noise factors as a result of the project. 5. All project development, engineering, and construction efforts must be coordinated with 7.6 LACMTA Regional Rail, LACMTA Real Estate, and the SCRRA. Any work Performed on the project infrastructure or property requiring access to the railroad ROW, shall be covered by specific Right -of -Entry permits with specific requirements. These may include permits for construction of infrastructure, and any future repairs, painting, graffiti removal, etc., including the use of overhead of cranes or any other equipment that could 7.7 potentially impact railroad operations and safety. Frequent access for maintenance tasks such as graffiti removal, will necessitate an active license agreement. This agreement will include an annual license fee, and other requirements that meet safety standards for access to a ROW with active rail operations. 7. Considering the proximity of the proposed project to the railroad ROW, trains will produce noise, vibration and visual impacts. A recorded Noise Easement Deed in favor of Metro is required, a form of which is attached. The easement recorded in the Deed will extend to 7.8 successors and tenants, as well. In addition, any noise mitigation required for the project will be borne by the developers of the project and not Metro or the operating railroads. Active Transportation For Option B of the intersection improvements for Arch Street/12th Street/Placerita Canyon and 7.9 proposed Dockweiler Drive: Roundabout design shall accommodate people on bicycles. Refer to AASHTO's Guide for the Development of Bicycle Facilities (2012) for consideration of bicycle travel at roundabouts (g4.12.11). Congestion Management Program Beyond impacts to Metro facilities and operations, Metro must also notify the applicant of state 7.10 requirements. A Transportation Impact Analysis (fIA), with roadway and transit components, is required under the State of California Congestion Management Program (CM P) statute. The CM TIA Page 2 of 3 The Lyons Ave/Dockweiler Drive Extension Project Notice of Availability EIR— Metro Comments October 16, 2017 Guidelines are published in the "2010 Congestion Management Program for Los Angeles County," Appendix D (attached). The geographic area examined in the TIA must include the following, at a minimum: 1. All CMP arterial monitoring intersections, including monitored freeway on/off-ramp intersections, where the proposed project will add 50 or more trips during either the a.m. or p.m. weekday peak hour (of adjacent street traffic). 2. If CMP arterial segments are being analyzed rather than intersections, the study area must include all segments where the proposed project will add 50 or more peak hour trips (total of both directions). Within the study area, the TIA must analyze at least one segment between monitored CMP intersections. 3. Mainline freeway -monitoring locations where the project will add 150 or more trips, in either direction, during either the a.m. or p.m. weekday peak hour. 4. Caltrans must also be consulted through the NOP process to identify other specific locations to be analyzed on the state highway system. The CMP TIA requirement also contains two separate impact studies covering roadways and transit, as outlined in Sections D.8.1 — D.9.4. If the TIA identifies no facilities for study based on the criteria above, no further traffic analysis is required. However, projects must still consider transit impacts. For all CMP TIA requirements please see the attached guidelines. 7.10 If you have any questions regarding this response, please contact Derek Hull at 213-922-3051 or by 7.11 email at DevReview@metro.net.

This section provides detailed travel statistics for the Los Angeles area which will he updated on an ongoing basis. Updates will he distrihuted to all local jurisdictions when available. In order to ensure that impact analyses reflect the best available information, lead agencies may also contact MTA at the time ofstudy initiation. Please contact MTA staff to request the most recent release of "Baseline Travel Data for CMP TIAs. " D.1 OBJECTIVE OF GUIDELINES The following guidelines are intended to assist local agencies in evaluating impacts of land use decisions on the Congestion Management Program (CMP) system, through preparation of a regional transportation impact analysis (TIA). The following are the basic objectives of these guidelines: ❑ Promote consistency in the studies conducted by different jurisdictions, while maintaining flexibility for the variety of project types which could be affected by these guidelines. ❑ Establish procedures which can be implemented within existing project review processes and without ongoing review by MTA. ❑ Provide guidelines which can be implemented immediately, with the full intention of subsequent review and possible revision. These guidelines are based on specific requirements of the Congestion Management Program, and travel data sources available specifically for Los Angeles County. References are listed in Section D.10 which provide additional information on possible methodologies and available resources for conducting TIAs. D.2 GENERAL PROVISIONS Exhibit D-7 provides the model resolution that local jurisdictions adopted containing CMP TIA procedures in 1993. TIA requirements should be fulfilled within the existing environmental review process, extending local traffic impact studies to include impacts to the regional system. In order to monitor activities affected by these requirements, Notices of Preparation (NOPs) must be submitted to MTA as a responsible agency. Formal MTA approval of individual TIAs is not required. The following sections describe CMP TIA requirements in detail. In general, the competing objectives of consistency & flexibility have been addressed by specifying standard, or minimum, requirements and requiring documentation when a TIA varies from these standards. 2010 Congestion Management Program for Los Angeles County APPENDIX D -GUIDELINES FOR CMP TRANSPORTATION IMPACT ANALYSIS PAGE D-2 D.3 PROJECTS SUBJECT TO ANALYSIS In general a CMP TIA is required for all projects required to prepare an Environmental Impact Report (EIR) based on local determination. A TIA is not required if the lead agency for the EIR finds that traffic is not a significant issue, and does not require local or regional traffic impact analysis in the EIR. Please refer to Chapter 5 for more detailed information. CMP TIA guidelines, particularly intersection analyses, are largely geared toward analysis of projects where land use types and design details are known. Where likely land uses are not defined (such as where project descriptions are limited to zoning designation and parcel size with no information on access location), the level of detail in the TIA may be adjusted accordingly. This may apply, for example, to some redevelopment areas and citywide general plans, or community level specific plans. In such cases, where project definition is insufficient for meaningful intersection level of service analysis, CMP arterial segment analysis may substitute for intersection analysis. DA STUDY AREA The geographic area examined in the TIA must include the following, at a minimum: ❑ All CMP arterial monitoring intersections, including monitored freeway on- or off -ramp intersections, where the proposed project will add 50 or more trips during either the AM or PM weekday peak hours (of adjacent street traffic). ❑ If CMP arterial segments are being analyzed rather than intersections (see Section D.3), the study area must include all segments where the proposed project will add 50 or more peak hour trips (total of both directions). Within the study area, the TIA must analyze at least one segment between monitored CMP intersections. ❑ Mainline freeway monitoring locations where the project will add 150 or more trips, in either direction, during either the AM or PM weekday peak hours. ❑ Caltrans must also be consulted through the Notice of Preparation (NOP) process to identify other specific locations to be analyzed on the state highway system. If the TIA identifies no facilities for study based on these criteria, no further traffic analysis is required. However, projects must still consider transit impacts (Section D.8.4). D.5 BACKGROUND TRAFFIC CONDITIONS The following sections describe the procedures for documenting and estimating background, or non -project related traffic conditions. Note that for the purpose of a TIA, these background estimates must include traffic from all sources without regard to the exemptions specified in CMP statute (e.g., traffic generated by the provision of low and very low income housing, or trips originating outside Los Angeles County. Refer to Chapter 5, Section 5.2.3 for a complete list of exempted projects). D.5.1 Existing Traffic Conditions. Existing traffic volumes and levels of service (LOS) on the CMP highway system within the study area must be documented. Traffic counts must 2010 Congestion Management Program for Los Angeles County APPENDIX D -GUIDELINES FOR CMP TRANSPORTATION IMPACT ANALYSIS PAGE D-3 be less than one year old at the time the study is initiated, and collected in accordance with CMP highway monitoring requirements (see Appendix A). Section D.8.1 describes TIA LOS calculation requirements in greater detail. Freeway traffic volume and LOS data provided by Caltrans is also provided in Appendix A. D.5.2 Selection of Horizon Year and Background Traffic Growth. Horizon year(s) selection is left to the lead agency, based on individual characteristics of the project being analyzed. In general, the horizon year should reflect a realistic estimate of the project completion date. For large developments phased over several years, review of intermediate milestones prior to buildout should also be considered. At a minimum, horizon year background traffic growth estimates must use the generalized growth factors shown in Exhibit D-1. These growth factors are based on regional modeling efforts, and estimate the general effect of cumulative development and other socioeconomic changes on traffic throughout the region. Beyond this minimum, selection among the various methodologies available to estimate horizon year background traffic in greater detail is left to the lead agency. Suggested approaches include consultation with the jurisdiction in which the intersection under study is located, in order to obtain more detailed traffic estimates based on ongoing development in the vicinity. D.G PROPOSED PROJECT TRAFFIC GENERATION Traffic generation estimates must conform to the procedures of the current edition of Trip Generation, by the Institute of Transportation Engineers (ITE). If an alternative methodology is used, the basis for this methodology must be fully documented. Increases in site traffic generation may be reduced for existing land uses to be removed, if the existing use was operating during the year the traffic counts were collected. Current traffic generation should be substantiated by actual driveway counts; however, if infeasible, traffic may be estimated based on a methodology consistent with that used for the proposed use. Regional transportation impact analysis also requires consideration of trip lengths. Total site traffic generation must therefore be divided into work and non -work -related trip purposes in order to reflect observed trip length differences. Exhibit D-2 provides factors which indicate trip purpose breakdowns for various land use types. For lead agencies who also participate in CMP highway monitoring, it is recommended that any traffic counts on CMP facilities needed to prepare the TIA should be done in the manner outlined in Chapter 2 and Appendix A. If the TIA traffic counts are taken within one year of the deadline for submittal of CMP highway monitoring data, the local jurisdiction would save the cost of having to conduct the traffic counts twice. D.7 TRIP DISTRIBUTION For trip distribution by direct/manual assignment, generalized trip distribution factors are provided in Exhibit D-3, based on regional modeling efforts. These factors indicate Regional Statistical Area (RSA) -level tripmaking for work and non -work trip purposes. 2010 Congestion Management Program for Los Angeles County APPENDIX D -GUIDELINES FOR CMP TRANSPORTATION IMPACT ANALYSIS PAGE D-4 (These RSAs are illustrated in Exhibit D-4.) For locations where it is difficult to determine the project site RSA, census tract/RSA correspondence tables are available from MTA. Exhibit D-5 describes a general approach to applying the preceding factors. Project trip distribution must be consistent with these trip distribution and purpose factors; the basis for variation must be documented. Local agency travel demand models disaggregated from the SCAG regional model are presumed to conform to this requirement, as long as the trip distribution functions are consistent with the regional distribution patterns. For retail commercial developments, alternative trip distribution factors may be appropriate based on the market area for the specific planned use. Such market area analysis must clearly identify the basis for the trip distribution pattern expected. D.8 IMPACT ANALYSIS CMP Transportation Impact Analyses contain two separate impact studies covering roadways and transit. Section Nos. D.8.1-D.8.3 cover required roadway analysis while Section No. D.8.4 covers the required transit impact analysis. Section Nos. D.9.1-D.9.4 define the requirement for discussion and evaluation of alternative mitigation measures. D.8.1 Intersection Level of Service Analysis. The LA County CMP recognizes that individual jurisdictions have wide ranging experience with LOS analysis, reflecting the variety of community characteristics, traffic controls and street standards throughout the county. As a result, the CMP acknowledges the possibility that no single set of assumptions should be mandated for all TIAs within the county. However, in order to promote consistency in the TIAs prepared by different jurisdictions, CMP TIAs must conduct intersection LOS calculations using either of the following methods: ❑ The Intersection Capacity Utilization (ICU) method as specified for CMP highway monitoring (see Appendix A); or ❑ The Critical Movement Analysis (CMA) / Circular 212 method. Variation from the standard assumptions under either of these methods for circumstances at particular intersections must be fully documented. TIAs using the 1985 or 1994 Highway Capacity Manual (HCM) operational analysis must provide converted volume -to -capacity based LOS values, as specified for CMP highway monitoring in Appendix A. D.8.2 Arterial Segment Analysis. For TIAs involving arterial segment analysis, volume -to - capacity ratios must be calculated for each segment and LOS values assigned using the V/ C-LOS equivalency specified for arterial intersections. A capacity of 800 vehicles per hour per through traffic lane must be used, unless localized conditions necessitate alternative values to approximate current intersection congestion levels. 2010 Congestion Management Program for Los Angeles County APPENDIX D -GUIDELINES FOR CMP TRANSPORTATION IMPACT ANALYSIS PAGE D-5 D.8.3 Freeway Segment (Mainline) Analysis. For the purpose of CMP TIAs, a simplified analysis of freeway impacts is required. This analysis consists of a demand -to -capacity calculation for the affected segments, and is indicated in Exhibit D-6. D.8.4 Transit Impact Review. CMP transit analysis requirements are met by completing and incorporating into an EIR the following transit impact analysis: ❑ Evidence that affected transit operators received the Notice of Preparation. ❑ A summary of existing transit services in the project area. Include local fixed -route services within a I/ mile radius of the project; express bus routes within a 2 mile radius of the project, and; rail service within a 2 mile radius of the project. ❑ Information on trip generation and mode assignment for both AM and PM peak hour periods as well as for daily periods. Trips assigned to transit will also need to be calculated for the same peak hour and daily periods. Peak hours are defined as 7:30- 8:30 AM and 4:30-5:30 PM. Both "peak hour" and "daily" refer to average weekdays, unless special seasonal variations are expected. If expected, seasonal variations should be described. ❑ Documentation of the assumption and analyses that were used to determine the number and percent of trips assigned to transit. Trips assigned to transit may be calculated along the following guidelines: ➢ Multiply the total trips generated by 1.4 to convert vehicle trips to person trips; ➢ For each time period, multiply the result by one of the following factors: 3.5 % of Total Person Trips Generated for most cases, except: 10% primarily Residential within 1/4 mile of a CMP transit center 15 % primarily Commercial within 1/4 mile of a CMP transit center 7% primarily Residential within 1/4 mile of a CMP multi -modal transportation center 9% primarily Commercial within 1/4 mile of a CMP multi -modal transportation center 5 % primarily Residential within 1/4 mile of a CMP transit corridor 7% primarily Commercial within 1/4 mile of a CMP transit corridor 0% if no fixed route transit services operate within one mile of the project To determine whether a project is primarily residential or commercial in nature, please refer to the CMP land use categories listed and defined in Appendix E, Guidelines for New Development Activity Tracking and Self Certification. For projects that are only partially within the above one -quarter mile radius, the base rate (3.5 % of total trips generated) should be applied to all of the project buildings that touch the radius perimeter. ❑ Information on facilities and/or programs that will be incorporated in the development plan that will encourage public transit use. Include not only the jurisdiction's TDM Ordinance measures, but other project specific measures. 2010 Congestion Management Program for Los Angeles County APPENDIX D -GUIDELINES FOR CMP TRANSPORTATION IMPACT ANALYSIS PAGE D-6 ❑ Analysis of expected project impacts on current and future transit services and proposed project mitigation measures, and; ❑ Selection of final mitigation measures remains at the discretion of the local jurisdiction/lead agency. Once a mitigation program is selected, the jurisdiction self - monitors implementation through the existing mitigation monitoring requirements of CEQA. D.9 IDENTIFICATION AND EVALUATION OF MITIGATION D.9.1 Criteria for Determining a Significant Impact. For purposes of the CMP, a significant impact occurs when the proposed project increases traffic demand on a CMP facility by 2% of capacity (V/C >_ 0.02), causing LOS F (V/C > 1.00); if the facility is already at LOS F, a significant impact occurs when the proposed project increases traffic demand on a CMP facility by 2% of capacity (V/C >_ 0.02). The lead agency may apply a more stringent criteria if desired. D.9.2 Identification of Mitigation. Once the project has been determined to cause a significant impact, the lead agency must investigate measures which will mitigate the impact of the project. Mitigation measures proposed must clearly indicate the following: ❑ Cost estimates, indicating the fair share costs to mitigate the impact of the proposed project. If the improvement from a proposed mitigation measure will exceed the impact of the project, the TIA must indicate the proportion of total mitigation costs which is attributable to the project. This fulfills the statutory requirement to exclude the costs of mitigating inter -regional trips. ❑ Implementation responsibilities. Where the agency responsible for implementing mitigation is not the lead agency, the TIA must document consultation with the implementing agency regarding project impacts, mitigation feasibility and responsibility. Final selection of mitigation measures remains at the discretion of the lead agency. The TIA must, however, provide a summary of impacts and mitigation measures. Once a mitigation program is selected, the jurisdiction self -monitors implementation through the mitigation monitoring requirements contained in CEQA. D.9.3 Project Contribution to Planned Regional Improvements. If the TIA concludes that project impacts will be mitigated by anticipated regional transportation improvements, such as rail transit or high occupancy vehicle facilities, the TIA must document: ❑ Any project contribution to the improvement, and ❑ The means by which trips generated at the site will access the regional facility. D.9.4 Transportation Demand Management (TDM). If the TIA concludes or assumes that project impacts will be reduced through the implementation of TDM measures, the TIA must document specific actions to be implemented by the project which substantiate these conclusions. 2010 Congestion Management Program for Los Angeles County APPENDIX D -GUIDELINES FOR CMP TRANSPORTATION IMPACT ANALYSIS PAGE D-7 D.10 REFERENCES 1.

The proposed Project includes the extension of Lyons Avcnuc from Railroad Avenue southeast to the proposed connection with Dockweiler Drive, to provide a T-intersection at Dockweiler Drive: the addition of a new at -grade railroad crossing east of the Railroad Avenue and Lyons Avenue intersection; and the extension of Dockweiler Drive from the approved extension at The Master's University northwest to connect with the intersection of Arch Street and 12th Street. The proposed Project also includes the closure of an at-gradc railroad crossing at the intersection of 13th Street and Railroad Avenue. The intersection at 13th Street would be modified, removing the northbound right turn lane and souhbound left turn lane and restricting the eastbound through movement. Metropolitan is a public agency and regional water wholesaler. It is comprised of 26 member public agcncies serving approximately 19 million people in portions of six counties in Southern California, including Los Angeles County. Metropolitan owns and operates facilities adjacent to the proposed Project Limits. As shown on the attached map, Metropolitan's Foothill Feeder, an approximately 16-foot, 9-inch inside - diameter pipeline within fee property rights -of -way, is located north of the proposed Project Limits. There are no Metropolitan facilities within the proposed Project Limits. Metropolitan must be allowed to maintain its rights -of -way and access to its facilities and properties at all times, to repair and maintain the current condition of those facilities. In order to avoid potential conflicts with Metropolitan's facilities and rights -of -way, we require that any design plans for any activity in the area of Metropolitan's pipelines or facilities be submitted for our review and written approval. Approval of the project is contingent on Metropolitan's approval of design plans for portions of the proposed project that could impact its facilities.

Introduction a. The following general guidelines should be followed for the design of proposed facilities and developments in the area of Metropolitan's facilities, fee properties, and/or easements. b. We require that 3 copies of your tentative and final record maps, grading, paving, street improvement, landscape, storm drain, and utility plans be submitted for our review and written approval as they pertain to Metropolitan's facilities, fee properties and/or easements, prior to the commencement of any construction work. 2a Plans, Parcel and Tract Maps The following are Metropolitan's requirements for the identification of its facilities, fee properties, and/or easements on your plans, parcel maps and tract maps; a. Metropolitan's fee properties and/or easements and its pipelines and other facilities must be fully shown and identified as Metropolitan's on all applicable plans. b. Metropolitan's fee properties and/or easements must be shown and identified as Metropolitan's with the official recording data on all applicable parcel and tract maps. C. Metropolitan's fee properties and/or easements and existing survey monuments must be dimensionally tied to the parcel or tract boundaries. d. Metropolitan's records of surveys must be referenced on the parcel and tract maps. 2 3. Maintenance of Access Alona Metropolitan's RiaFhts-of-Way a. Proposed cut or fill slopes exceeding 10 percent are normally not allowed within Metropolitan's fee properties or easements. This is required to facilitate the use of construction and maintenance equipment, and provide access to its aboveground and belowground facilities. b. We require that 16-foot-wide commercial --type driveway approaches be constructed on both sides of all streets crossing Metropolitan's rights -of -way. Openings are required in any -median island. Access ramps, if necessary, must be at least 16-feet-wide. Grades of ramps are normally not allowed to exceed 10 percent. If the slope of an access ramp must exceed 10 percent due to the topography, the ramp must be paved. We require a 40-foot-long level area on the driveway approach to access ramps where the ramp meets the street. At Metropolitan's fee properties, we may require fences and gates. C. The terms of Metropolitan's permanent easement deeds normally preclude the building or maintenance of structures of any nature or kind within its easements, to ensure safety and avoid interference with operation and maintenance of Metropolitan's pipelines or other facilities. Metropolitan must have vehicular access along the easements at all times for inspection,. patrolling, and for maintenance of the pipelines and other. facilities on a routine basis. We require a 20-foot-wide clear zone around all above -ground facilities for this routine access. This clear zone should slope away from our facility on a grade not to exceed 2 percent. We must also have access along the easements with construction equipment. An example of this is shown on Figure 1. d. The footings of any proposed buildings adjacent to Metropolitan's fee properties and/or easements must not encroach into the fee property or easement or impose additional loading on metropolitan's pipelines or other facilities therein. A typical situation is shown on Figure 2. Prints of the detail plans of the footings for any building or structure adjacent to the fee property or easement must be submitted for our review and written approval as. they pertain to the pipeline or other facilities therein. Also, roof eaves of buildings adjacent to the easement or fee property must not overhang into the fee property or easement area. e. Metropolitan's pipelines and other facilities, e.g. structures, manholes, equipment, survey monuments, etc. within its fee properties and/or easements must be protected from damage by the easement holder on Metropolitan's property or the property owner where Metropolitan has an easement, at no expense to Metropolitan. if the facility is a cathodic protection station it shall be located prior to any grading or excavation. The exact location, description and way of protection shall be shown on the related plans . for the easement area. 4. Easements on Metropolitan's PEogerty a. We encourage the use of Metropolitan's fee rights - of -•way by governmental agencies for public street and utility purposes, provided that such use does not interfere with Metropolitan's use of the property, the entire width of the property is accepted into the agency's public street system and fair market value is paid for such use of the right-of-way. b. Please contact the Director of Metropolitan's Right of Way and Land Division, telephone (213) 250-6302, concerning easements for landscaping, street, storm drain, sewer, water ❑r other public facilities proposed within Metropolitan's 1 fee properties. A map and legal description of the requested easements must be submitted. Also, written evidence must be submitted that shows the city or county will accept the easement for the specific purposes into its public system. The grant of the easement will be subject to Metropolitan's rights to use its land for water pipelines and related purposes to the same extent as if such grant had not been made. There will be a charge for the easement. Please note that, if entry is required on the property prior to issuance of the easement, an entry permit must be obtained. There will also be a charge for the entry permit. 5. Landscapinq Metropolitan's landscape guidelines for its fee properties and/or easements are as follows: a. A green belt may be allowed within Metropolitan's fee property or easement. b. All landscape plans shall show the location and size of Metropolitan's fee property and/or easement and the location and size of Metropolitan's pipeline or other facilities therein. - 4 - C. Absolutely no trees will be allowed within 15 feet of the centerline of Metropolitan's existing or future pipelines and facilities. d. Deep-rooted trees are prohibited within Metropolitan's fee properties and/or easements. Shallow - rooted trees are the only trees allowed. The shallow -rooted trees will not be permitted any closer than 15 feet from the centerline of the pipeline, and such trees shall not be taller than 25 feet with a root spread no greater than 20 feet in diameter at maturity. Shrubs, bushes, vines, and ground cover are permitted, but larger shrubs and bushes should not be planted directly over our pipeline. Turf is acceptable. We require submittal of landscape plans for Metropolitan's prior review and written approval. (See Figure 3). e. The landscape plans must contain provisions for Metropolitan's vehicular access at all times along its rights -of -way to its pipelines or facilities therein. Gates capable of accepting Metropolitan's locks are required in any fences across its rights -of -way. Also, any walks or drainage facilities across its access route must be constructed to AASHTO H-20 loading standards. t. Rights to landscape any of Metropolitan's fee properties must be acquired from its Right of Way and Land Division. Appropriate entry permits must be obtained prior to any entry on its property. There will be a charge for any entry permit or easements required. 6. Fencing Metropolitan requires that perimeter fencing of its fee properties and facilities be constructed'of universal chain link, 6 feet in height and topped with 3 strands of barbed wire angled upward and outward at a 45 degree angle or an approved equal for a total fence height of 7 feet. Suitable substitute fencing may be considered by Metropolitan. (please see Figure 5 for details). 7. Utilities in Metropolitan's Fee Properties and/or Easements or Adjacent to Its Pipeline in Public Streets Metropolitan's policy for the alinement of utilities permitted within its fee properties and/or easements and street sights -of -way is as follows: - 5 - a. Permanent structures, including catch basins, manholes, power poles, telephone riser boxes, etc., shall not be located within its fee properties and/or easements. b. We request that permanent utility structures within public streets, in which Metropolitan's facilities are constructed under the Metropolitan Water District Act, be placed as far from our pipeline as possible, but not closer than 5 feet from the outside of our pipeline. C. The installation of utilities over or under Metropolitan's pipeline(s) must be in accordance with the requirements shown on the enclosed prints of Drawings Nos. C-11532 and C-9547. Whenever possible we request a minimum of one foot clearance between Metropolitan's pipe and your facility. Temporary support of Metropolitan's pipe may also be required at undercrossings ❑f its pipe in an open trench. The temporary support plans must be reviewed and approved by Metropolitan. d. Lateral utility crossings of Metropolitan's pipelines must be as perpendicular to its pipeline alinement as practical. Prior to any excavation our pipeline shall be located manually and any excavation within two feet of our pipeline must be done by hand. This shall be noted on the appropriate drawings. e. Utilities constructed longitudinally within Metropolitan's rights -of -way must be located outside the theoretical trench prism for uncovering its pipeline and must be located parallel to and as close to its rights - of -way lines as practical. f. When piping is jacked or installed in jacked casing or tunnel under Metropolitan's pipe, there must be at least two feet of vertical clearance between the bottom of Metropolitan's pipe and the top of the jacked pipe, jacked casing or tunnel. We also require that detail drawings of the shoring for the jacking or tunneling pits be submitted for our review and approval. Provisions must be made to grout any voids around the exterior of the jacked pipe, jacked casing or tunnel. If the piping is installed in a jacked casing or tunnel the annular space between the piping and the jacked casing or tunnel must be filled with grout. :WIM g. Overhead electrical and telephone line requirements: 1) Conductor clearances are to conform to the California State Public Utilities Commission, General Order 950 for Overhead Electrical Line Construction or at a greater clearance if required by Metropolitan. Under no circumstances shall clearance be less than 35 feet. 2) A marker must be attached to the power pole showing the ground clearance and line voltage, to help prevent damage to your facilities during maintenance or other work being done in the area. 3) Line clearance over Metropolitan's fee properties and/or easements shall be shown on the drawing to indicate the lowest point of the line under the most adverse conditions including consideration of sag, wind load, temperature change, and support type. We require that overhead lines be located at least 30 feet laterally away from all above -ground structures on the pipelines. 4) When underground electrical conduits, 120 volts or greater, are installed within Metropolitan's fee property and/or easement, the conduits must be incased in a minimum of three inches of red concrete. Where possible, above ground warning signs must also be placed at the right-of-way lines where the conduits enter and exit the right--of-way. h. The construction of sewerlines in Metropolitan's fee properties and/or easements must conform to the California Department of Health Services Criteria for the Separation of Water Mains and Sanitary Services and the local City or County Health Code Ordinance as it relates to installation of sewers in the vicinity of pressure waterlines. The construction of sewerlines should also conform to these standards in street rights -of- way. i. Cross sections shall be provided for all pipeline crossings showing Metropolitan's fee property and/or easement limits and the location of our pipeline(s). The exact locations of the crossing pipelines and their elevations shall be marked on as -built drawings for our information. - 7 - j. Potholing of Metropolitan's pipeline is required if the vertical clearance between a utility and Metropolitan's pipeline is indicated on the plan to be one foot or less. If the indicated clearance is between one and two feet, potholing is suggested. Metropolitan will provide a representative to assists others a.n locating and identifying its pipeline. Two -working days notice is requested. k. Adequate shoring and bracing is required for the full depth of the trench when the excavation encroaches within the zone shown on Figure 4. 1. The location of utilities within Metropolitan's fee property and/or easement shall be plainly marked to help prevent damage during maintenance or other work done in the area. Detectable tape over buried utilities should be placed a minimum of 12 inches above the utility and shall conform to the following requirements: ly Water pipeline: A two-inch blue warning tape shall be imprinted with: "CAUTION BURIED WATER PIPELINE" 2) Gas, oil, or chemical pipeline: A two-inch yellow warning tape shall be imprinted with: "CAUTION BURIED PIPELINE" 3) Sewer or storm drain pipeline: A two-inch green warning tape shall be imprinted with: "CAUTION BURIED PIPELINE" 4) Electric, street lighting, or traffic signals conduit: A two-inch red warning tape shall be imprinted with: "CAUTION BURIED CONDUIT" 5) Telephone, or television conduits A two-inch orange warning tape shall be imprinted with: "CAUTION BURIED CONDUIT" _ 8 m. Cathodic Protection requirements: 1) If there is a cathodic protection station for Metropolitan's pipeline in the area of the proposed work, it shall be located prior to any grading or excavation. The exact location, description and manner of protection shall be shown on all applicable plans. Please contact Metropolitan's Corrosion Engineering Section, located at Metropolitan's F. E. Weymouth Softening and Filtration Plant, 700 North Moreno Avenue, La Verne, California 91750, telephone (714) 593-7474, for the locations of Metropolitan's cathodic protection stations. 2) If an induced -current cathodic protection system is to be installed on any pipeline crossing Metropolitan's pipeline, please contact Mr. Wayne E. Risner at .(714) 593-7474 or (213) 250-5085. He will review the proposed system and determine if any conflicts will arise with the existing cathodic protection systems installed by Metropolitan. 3) Within Metropolitan's rights -of -way, pipelines and carrier pipes (casings) shall be coated with an approved protective coating to conform to Metropolitan's requirements, and shall be maintained in a neat and orderly condition as directed by Metropolitan. The application and monitoring of cathodic protection on the pipeline and casing shall conform to Title 49 of the Code of Federal,Regulations, Part 195. 4) If a steel carrier pipe (casing) is used: (a) Cathodic protection shall be provided by use of a sacrificial magnesium anode (a sketch showing the cathodic protection details can be provided for the designers information). (b) The steel Carrier pipe shall be protected with a coal tar enamel coating inside and out in accordance with AWWA C203 specification. n. All trenches shall be excavated to comply with the CAL/OSHA Construction Safety Orders, Article 6, beginning with Sections 1539 through 1547. Trench backfill shall be placed in 8-inch lifts and shall be compacted to 95 percent relative compaction (ASTM D698) across roadways and through protective dikes. Trench backf:i.11 elsewhere will be compacted to 90 percent relative compaction (ASTM D698). - 9 - o. Control cables connected with the operation of Metropolitan's system are buried within streets, its fee properties and/or easements. The locations and elevations of these cables shall be shown on the drawings. The drawings shall note that prior to any excavation in the area, the control cables shall be located and measures shall be taken by the contractor to protect the cables in place. p. Metropolitan is a member of Underground Service Alert (USA). The contractor (excavator) shall contact USA at 1-800-422-4133 (Southern California) at least 48 hours prior to starting any excavation work. The contractor will be liable for any damage to Metropolitan's facilities as a result of the construction. 8. Paramount Right Facilities constructed within Metropolitan's fee properties and/or easements shall be subject to the paramount right of Metropolitan to use its fee properties and/or easements for the purpose for which they were acquired. If at any time Metropolitan or its assigns should, in the exercise of their rights, find it necessary to remove any of the facilities from the fee properties and/or easements, such removal and replacement shall be at the expense of the owner of the facility. 9. Modification of Metropolitan's Facilities When a manhole or other of Metropolitan's facilities must be modified to accommodate your construction or recons- truction, Metropolitan will modify the facilities with its forces. This should be noted on the construction plans. The estimated cost to perform this modification will be given to you and we will require a deposit for this amount before the work is performed. Once the deposit is received, we will schedule the work. Our forces will coordinate the work with your contractor. Our final billing will be based on actual cost incurred, and will include materials, construction, engineering plan review, inspection, and administrative overhead charges calculated in accordance with Metropolitan's standard accounting practices. If the cost is less than the deposit, a refund will be made; however, if the cost exceeds the deposit, an invoice will be forwarded for payment of the additional amount. =U6W 10. Drainage a. Residential or commercial development typically increases and concentrates the peak storm water runoff as well as the total yearly storm runoff from an area, thereby increasing the requirements for storm drain facilities downstream of the development. Also, throughout the year water from landscape irrigation, car washing, and other outdoor domestic water uses flows into the storm drainage system resulting in weed abatement, insect infestation, obstructed access and other problems. Therefore, it is Metropolitan's usual practice not to approve plans that show discharge of drainage from developments onto its fee properties and/or easements. b. If water must be carried across or discharged onto Metropolitan's fee properties and/or easements, Metropolitan will insist that plans for development provide that it be carried by closed conduit or lined open channel approved in writing by Metropolitan. Also the drainage facilities must be maintained by others, e.g., city, county, homeowners association, etc. If the development proposes changes to existing drainage features, then the developer shall make provisions to provide Lor replacement and these changes must be approved by Metropolitan in writing. 1.1.. Construction Coordination During construction, Metropolitan's field representative will make periodic inspections. We request that a stipulation be added to the plans or specifications for notification of Mr. of Metropolitan's Operations Services Branch, telephone 213) 250- , at least two working days prior to any work in the vicinity of our facilities. 12. Pipeline Loading Restrictions a. Metropolitan's pipelines and conduits vary in structural strength, and some are not adequate for AASHTO H-20 loading. Therefore, specific loads over the specific sections of pipe or conduit must be reviewed and approved by Metropolitan. However, Metropolitan's pipelines are typically adequate for AASHT0 9-20 Loading provided that the cover over the pipeline is not less than four feet or the cover is not substantially increased. If the temporary cover over the pipeline during construction is between three and four feet, equipment must restricted to that which I mposes loads no greater than AASHTO H-10. If the cover is between two and three feet, equipment must be restricted to that of a Caterpillar D-4 tract -type tractor. If the cover is less than two feet, only hand equipment may be used. Also, if the contractor plans to use any equipment over Metropolitan's pipeline which will impose loads greater than AASHTO H-201 it will be necessary to submit the specifications of such equipment for our review and approval at least one week prior to its use. More restrictive requirements may apply to the loading guideline over the San Diego Pipelines 1 and 2, portions of the Orange County Feeder, and the Colorado River Aqueduct. Please contact us for loading restrictions on all of Metropolitan's pipelines and conduits. b. The existing cover over the pipeline shall be maintained unless Metropolitan determines that proposed changes do not pose a hazard to the integrity of the pipeline or an impediment to its maintenance. 13. Blasting a. At least 20 days prior to the start of any drilling for rock excavation blasting, or any blasting, in the vicinity of Metropolitan's facilities, a two-part preliminary conceptual plan shall be submitted to Metropolitan as follows: b. Part 1 of the conceptual plan shall include a complete summary of proposed transportation, handling, storage, and use of explosions. C. Part 2 shall include the proposed general concept for blasting, including controlled blasting techniques and controls of .noise, fly rock, airblast, and ground vibration. 14. CEQA Requirements a. When Environmental Documents Have Not Been Prepared 1) Regulations implementing the California Environmental Quality Act (CEQA) require that Metropolitan have an opportunity to consult with the agency or consultants preparing any environmental documentation. We are required to review and consider the environmental effects of the project as shown in the'Negative Declaration or Environmental Impact Report (EIR) prepared for your project before committing Metropolitan to approve your request. - 12 - 2) In order to ensure compliance with the regulations implementing CEQA where Metropolitan is not the Lead Agency, the following minimum procedures to ensure compliance with the Act have been established: a) Metropolitan shall be timely advised of any determination that a Categorical Exemption applies to the project. The Lead Agency is to advise Metropolitan that it and other agencies participating in the project have complied with the requirements of CEQA prior to Metropolitan's participation. b) Metropolitan is to be consulted during the preparation of the Negative Declaration or EIR. c) Metropolitan is to review and submit any necessary comments on the Negative Declaration or draft EIR. d) Metropolitan is to be indemnified for any costs or liability arising out of any violation of any laws or regulations including but not limited to the California Environmental Quality Act and its implementing regulations. b. When Environmental Documents Have Seen Prepared If envirormental documents have been prepared for your project, please furnish us a copy for our review and files in a timely manner so that we may have sufficient time to review and comment. The following steps must also be accomplished: 1) The Lead Agency is to advise Metropolitan that it and other agencies participating in the project have complied with the requirements of CEQA prior to Metropolitan's participation. Z) You must agree to indemnify Metropolitan, its officers, engineers, and agents for any costs or liability arising out of any violation of any laws or regulations including but not limited to the California Environmental Quality Act and its implementing regulations. 15. Metropolitan's Plan -Review Cost a. An engineering review of your proposed facilities and developments and the preparation of a letter response - 13 giving Metropolitan's comments, requirements and/or approval that will require 8 man-hours or less of effort is typically performed at no cost to the developer, unless a facility must be modified where Metropolitan has superior rights. If an engineering review and letter response requires more than 8 man-hours of effort by Metropolitan to determine if the proposed facility or development is compatible with its facilities, or if modifications to Metropolitan's manhole(s) or other facilities will be required, then all of Metropolitan's costs associated with the project must be paid by the developer, unless the developer has superior rights. b. A deposit of funds will be required from the developer before Metropolitan can begin its detailed engineering plan review that will exceed 8 hours, The amount of the required deposit will• be determined after a cursory review of the plans for the proposed development. C. Metropolitan's final billing will be based on actual cost incurred, and will include engineering plan review, inspection, materials, construction, and administrative overhead charges calculated in accordance. with Metropolitan's standard accounting practices. If the cost is less than the deposit, a refund will be made; however, if the cost exceeds the deposit, an invoice will be forwarded for payment of the additional amount. Additional deposits may be required if the cost of Metropolitan's review exceeds the amount of the initial deposit. 16. Caution We advise you that Metropolitan's plan reviews and responses are based upon information available to Metropolitan which was prepared by or on behalf of Metropolitan for general record purposes only. Such information may not be sufficiently detailed or accurate for your purposes. No warranty of any kind, either express or implied, is attached to the information therein conveyed as to its accuracy, and no inference should be drawn from Metropolitan's failure to comment on any aspect of your project. You are therefore cautioned to make such surveys and other field investigations as you may deem prudent to assure yourself that any plans for your project are correct. - 14 - 17.

Impact Report (DEIR) for the Lyons Avenue/Dockweiler Drive Extension Project. SoCalGas understands that the proposed project would involve an extension of Lyons Avenue from Railroad Avenue southeast 9.1 to connect with Dockweiler Drive, creating a T-intersection, The project would also include the addition of a new at - grade railroad crossing east of the Railroad Avenue and Lyons Avenue intersection, as well as another extension of Dockweiler Drive from the approved extension at The Master's University northwest to connect with the intersection of Arch Street and 1.2th Street. We respectfully request that the following comments be incorporated in the administrative record for the DEIR: • SoCalGas has several underground facilities in the area that the proposed road extension would traverse. These include a high-pressure transmission line 24 inches in diameter, at the Lyons Avenue/Railroad Avenue intersection. Several medium pressure distribution lines located at the Lyons Avenue/Railroad Avenue intersection and along 121 Street and Placerita Canyon Road where the proposed extension would cross. • SoCalGas recommends that the project proponent call Underground Service Alert at 811 at least two business days prior to performing any excavation work for the proposed project. Underground Service Alert will coordinate with SoCalGas and other Utility owners in the area to mark the locations of buried utility -owned lines. • Should it be determined that the proposed project may require SoCalGas to abandon and/or relocate or otherwise modify any portion of its existing natural gas lines, SoCalGas respectfully requests that the County and/or the project proponent coordinate with us by calling (800) 42.7-2000 for Non-residential to follow-up on this matter. 9.2 N72az Once again, we appreciate the opportunity to comment on the DEIR.

October 16, 2017 Ms. Carla Callahan Senior Engineer SOUTHERN CALIFORNIA REGIONAL RAIL AUTHORITY one Gateway Plaza Twelfth Floor Los Angeles, CA 90012 metrolinktrains.com City of Santa ClaritalPublic Works 23920 Valencia Blvd. — Suite 300 Santa Clarita, CA 91355 RE: Notice of Availability of a Draft Environmental Impact Report (DEIR) for Lyons AvenuelDockweiler Drive Extension Project Dear Ms. Callahan: The Southern California Regional Rail Authority (SCRRA) has received the above noted DEIR for the Lyons AvenuelDockweiler Drive Extension Project. Thank you for the opportunity to comment on key issues relative to SCRRA and operations of the railroad that crosses the project location. As background information, SCRRA is a five -county Joint Powers Authority (JPA) that operates the regional commuter rail system known as Metrolink. Additionally, SCRRA provides rail engineering, construction, operations and maintenance services to its five JPA member agencies. The JPA consists of the Los Angeles County Metropolitan Transportation Authority (METRO), San Bernardino County Transportation Authority (SBCTA), Orange County Transportation Authority 10.1 (OCTA), Riverside County Transportation Commission (RCTC) and Ventura County Transportation Commission (VCTC). The railroad right of way where the project is located is owned by Metro and operated, dispatched and maintained by SCRRA. The Lyons Avenue extension project (as proposed) would be located at railroad milepost 30.16 on our Valley Subdivision rail line. Currently, there are 30 Metrolink commuter trains and 5 Union Pacific (UPRR) freight trains that pass this location on a daily basis. As this project involves a new at -grade crossing proposal of the very active rail line we offer the following initial comments: 1. Noise from warning devices and train horns will be generated from creation of new at -grade crossing. Trains operate 7 days a week and 24 hours a day. 10.2 Trains do generate noise both from operations and also from Federal requirements to sound their horn as warning to pedestrians and motorists when approaching at -grade crossings. 2. SCRRA's adopted policies discourage the creation of new at -grade 10.3 cossings. SCRRA has adopted Resolution 98-21 Regarding Highway -Rail Notice of Availability of a DEIR for Lyons Avenue/Dockweiler Drive Extension Project Page 2 Grade Crossings (Exhibit A) and a new SCRRA Highway -Rail Grade Crossings Recommended Design Practices and Standards Manual. in Chapter 7.4 of the manual it states that "Before considering a new highway -rail grade crossing, the first alternative that should always be considered is a grade -separated crossing." In Resolution 98-21 it states in Item 2 that SCRRA shall oppose the creation of new rail -- highway grade crossings to the extent feasible on all regional passenger rail lines. Item 6 of the same resolution states that The SCRRA would support the creation of a new rail -highway grade crossing only if improvements to other grade crossings, including elimination of grade crossing(s), are made part of the creation of the new grade crossing which together clearly improve public convenience and safety. In order for SCRRA to even consider the possibility of 10.3 supporting a new at -grade crossing the City would have to prove that adequate mitigation measures would be in place to make the new crossing application package safer than what exists today. A closure of a smaller less used at -grade crossing for a new larger multi -lane at -grade crossing (1 for 1 swap) does not prove that the overall safety factor for all crossings would be increased. A clear "reduction in risk" for SCRRA and member agency Metro must be clearly shown. Your DEIR only shows closing 13th Street and opening of a new multi -lane crossing of Lyons Avenue. Other safety mitigation measures could include the closure of other at -grade crossings within the city's jurisdiction, and upgrade of other existing at -grade crossings to the latest standards as noted in the Design Manual (refer to SCRRA's previous letter response to NOP of DEIR dated 10-22- 13 for possible other safety mitigations), 3. A formal application to the California Public Utilities Commission (CPUC) needs to be made with letters of concurrence from all stakeholders (Metro, 10.4 SCRRA and UPRR), The CPUC has ultimate jurisdiction for approval of new at - grade crossings in California. Our preference at this time would be that a grade separated crossing proposal be put in place in lieu of the at -grade option. 4. At -grade crossing creates operational and safety issues. The location of the proposed crossing would traverse 2 tracks in the immediate vicinity of an SCRRA control point (CP Hood). The location of the crossing signals and gates could 10.5 impact line of sight for train engineer needing to see the controlling signals for CP Hood to move from one track to another. This potential operational issue could force relocation or modifications to the control point at city's expense. 5. A new at -grade crossing so close to an existing station could present additional traffic impacts when the trains are sitting in the station. The gates would either stay down or have to time-out and go back up when the train is stopped in the station. A thorough analysis would have to be done to determine if an at -grade crossing is feasible within the control point location. The 10.6 traffic impacts if the gates remain in the down position to the new intersection should be studied. This type of situation exists at other Metrolink station locations near crossings and does present some safety concerns and complaints. Notice of Availability of a DEIR for Lyons Avenue/Dockweiler Drive Extension Project Page 3 6. Pedestrian safety and potential trespassing issues to and from the Newhall Station should be considered in the design of Lyons Avenue extension. An additional safety concern would be the fact that the shortest route for pedestrians using the new proposed crossing to get to the station would be to trespass into 10.7 the railroad right of way from the sidewalk and off the ends of the existing platforms. Trespassing in the right of way to or from the station would need to be addressed If you have any questions on this ❑EIR, please contact Ron Mathieu at 213-452-0456 or 10.8 via e-mail' at mathieur@scrra.net. 67incerely, fid&d,P Roderick Diaz Director Planning & Development Cc: Jeanet Owens, Metro Chi Cheung To, CPUC Ron Mathieu, SCRRA Justin Forneili, SCRRA Jerone Hurst, SCRRA Whitney O'Neil, SCRRA Sherita Coffelt, SCRRA h Po P I or T 1IL 80 O9 Ffi flM CALIFO1TNIA G`ti';'MONA HAR, A(JT1°10l,` IT°Y HUMMING!

We have always favored the Market Street connection and continue to do so. Here's what we favor: bring Dockweiler, as planned, down to Arch or Pine. Instead of having traffic bear right to the 13'h Street crossing, have it bear left to Market Street. Market Street is an already -improved crossing. Traffic can go right, left or straight. It leads both to Railroad for north and south travel or directly into Downtown Newhall. 13' Street, on the other hand, is a T-intersection. No matter how much it is improved, it will remain a T-intersection. It has many drawbacks: • It floods easily. • It is oven overcrowded with long waits. • It does not lead directly to any destination. Traffic waiting to turn in from the north often lines up past 141h Street cutting off a lane of traffic on Railroad. • The U-turn allowed from the north further impedes access. The I P Street crossing is within. Placerita Canyon's Special Standards District in which the City guarantees our rural equestrian neighborhood. Directing more traffic into the Special Standards District will require a General Plan Amendment. Please choose the simplest and best alternative and take the Dockweiler traffic down to Arch or Pine and then over to Market Street.

As a first point, the Dockweiler Project is neither wanted nor needed especially by that sector of the Santa Clarita that will be the most significantly and severely adversely impacted, namely, PCPOA. The approval of the Dockweiler Project and the Lyons Avenue Crossing Project are in derogation to the protections intended by the Placerita Canyon Special Standards District, enacted "to protect, maintain, preserve and enhance the secluded, rural equestrian character of the community." In fact, if and when constructed, the Dockweiler Project w i d eviscerate the protections intended Placerita Canon Special Standards District to protect the community against uncontrolled development in the future, and to protect against harm and damage to the existing community, its structures, and its residents. The City is proposing to construct the Proposed Dockweiler Drive Alignment Project directly through the heart and in violation of the Placerita Canyon Special Standards District, 11� extending Dockweiler Avenuc to extend it to Lyons Avenue, across the SC;RRA railroad tracks, essentially connecting Sierra I Iighway (even though it will never be connected to an onramp to the 14 Freeway because it is too close to the existing freeway connections at Placerita Canyon and Newhall Avenue), by formalizing Dockweiler into becoming a major bypass to divert arld redirect tens of thousands of' cars daily from the 14 Freeway directly through the Placerita Special Standards District, across the proposed Lyons Avenue Crossing, and into the commercial center of Santa Clarita, then connecting on to the I-5 Freeway.

Kassan, P.E., dated May 26, 2010, submitted by PCPOA, incorporated herein by this reference.) 12.2 12.3 12.4 LAW OFFICES GRAHAM • VAAGE LLP Mayor Smyth and Members of the City Council City oi' Santa Clarita October 16, 2017 Page 2 The City attempts to sanctify the intended Dockweiler Project in conjunction with the Lyons Avenue Project premised on its contention that they are consistent with the Gcncral flan which, of course, presupposes that the General Plan was f7awlcss, which it clearly is not because 12.5 it never proffered a specific combined Dowkweiler / Lyons Project which was subjected or has met current CEQA standards. The City has admitted such in its DE.IR..' As a bureaucratic diversion intended to dilute any opposition to the Dockweiler Project and its eventual intended tic to the Lyons Crossing, purported "alternatives" to the Lyons Avenue Crossing have been refercnced in the form of'crossings at 130 Street and Market Street. 12.6 neither- of which provides any support iirr the Dockweiler Project and its intended resulting flow of thousands of additional vehicles through the Placerita Specific Standards District. Aside from the major intended increase in traffic volume on Dockweiler, the proposed construction on Dockweiler itself will not meet current highway safety standards, as the gradient of 11.5% (based on the City's own analyses) far exceeds the legally allowable grade of less than 12.7 6%, immediately disqualifying Doweiter from available federal and state funding, causing the City to have to bear the sole cost and expense of millions of dollars to construct a substandard cross-towtl highway. In short, the Dockweiler Project effectively drops straight down a cliff to reach the river grade before crossing the railroad. Even more egregious is that the Dockweiler Project which would funnel these thousands of additional vehicles would be on a roadway that would be only 10-15 feet frorn some of the existing structures in an established multiple family 12.8 and condominium community.2 An even further defect on the list of defective analyses is the fact that the proposed Lyons Crossing will expose the railroad tracks to erosion and flood damage, as the constriction of the water course by the proposed Lyons Crossing wold raise the water level under high water storm 12.9 flows that overtop the elevation of the railroad.3 Placerita Canyon is already susceptible to poor ' "The proposed alignment of Dockweiler Drive through this existing residential neighborhood would not he consistent with the alignment identified within the Circulation Element and would not be compatible with respect to public safety and local residential street standards" If Dockweiler is constructed with two lanes of traffic in each direction, it would be extremely close to the existing condominiums at the top of the hill, even though fortner Community Development Director Paul Srotzman deceptively pledged to those residents that the planned expaltsioli WOUld never he built. ' Mike Hennaway of City of Santa Clarita stated in a December 14, 2009 email to Craig Kwasviewski, Senior Hydrologist / Project Engineer with HMK Engineering, that "...the profile of the (proposed Lyon's) bridge ... is below, the Water Surface Elevation ("WSF"") for both a 100 year clear flow and a 50 year burned -and -hulked flow," which means that the bridge would be beneath the level of flood waters in Newhall Creek, and in the event of a heavy rainstorm, the Placerita Canyon community of 450+ homes would be cut of'l' from evacuation and emergency support services by floodwaters cresting over the bridge. The overflows would also inundate the Downtown Newhall area, and the section in frorit of the new Newhall Library .could become a lake due to the built-up roadway required to be raised to meet the top of the tracks for an at -grade Crossing at Lyons. LAW OFFII_= GRAHAM ■ VAAGE LLP Mayor Smyth and Mcmbers of the City Council City of Santa Clarita October 16, 2017 Page 3 runoff creating flooding on 12`h Street near Placcritos, 1P Street, and other areas. Such constriction of water flow in the water course will exacerbate the already -existing water flow, 12.9 flooding, and drainage issues. Yet another unexplored issue relating to any expansion of Dockweiler is MWD's announced intention to expand its services with its planned 20 foot in diameter parallel feed pipe 12.10 through the Dockweiler alignment. Simply, the Lyons Crossing Project does not and cannot exist in the abstract without also fully considering and evaluating of the corresponding impacts of the proposed Dockweiler Project, because they are completely integrated in their intended purpose and use: piecemealing of contemplated Projects to prevent their full analyses and evaluation in their total context is a 12.11 direct violation of the fundamental requirements of CEQA. The City has failed to comply with CEQA in not completely combining the environmental analyses of Lyons Crossing Project along with the Dockweiler Project. There can be no viable (or legal) alternative Crossing that can be proposed unless and until the full context of the Dockweiler Project is included in the environmental review. The lesser of evils ---albeit still legally defective in the present context would he the Market Street Alternative, as it would be a better solution to address the access and circulation issues requiring 12.12 a crossing. That Crossing already exists and could be expanded, and Market Street has the advantage of having access from other parts of Railroad Street prior to the crossing at Railroad.. Newhall/Main St. (Pine and Arch St.) The 13"' Street alternative will never receive PIC approval. In addition to its objections stated herein, PCPOA restates its previously asserted objections to the proposed Lyons Crossing Project, as follows: Topic l: Aesthetics There wit] be significant impact to the scenic vistas and it will make significant impact to 12.13 the rural equestrian nature of the area. An at -grade crossing will mean raising the road bed five to six feet. This will impede the walkability in the section of Downtown Newhall currently undergoing redevelopment, and will virtually bury the historic jailhouse located almost adjacent to the proposed Crossing. The proposed Project will create light, noise and visual blight in a Special Standards District in which these uses are restricted. Topic 2: Agricultural Resources The proposed at -grade Crossing will alter an area near equestrian facilities. Tractors and other farm equipment are common on local streets; they also use the crossing presently at 13th 12.14 Street. Placerita Canyon is a Rural Equestrian Cornmunity, specifically so designated as a Special Standards District in Santa Clarita's UDC. LAW OFFICES GRAHAM • VAAGE LLP Mayor Smyth and Members of the City Council City of Santa Clarita October 16, 2017 Page 4 Topic 3: Air quality The Santa Clarita commercial center area is already out of compliance with Federal and 12.15 State clean air standards, and there will be at least three additional elements that have to be considered: more trains, more traffic, and longer waits for each vehicle to make the crossing, which will create even more air pollution in an area that is already suffering. Under the Global Warming Solutions Act of 2006, California emissions must be reduced to 1990 levels by the year 2020. The heavier volume of traffic in the heart of the commercial 12.16 and governmental center of Santa Clarita, combined with longer wait times, will result in more emissions not less in an already non -attainment area. Topic 4: Biological Resources The proposed Lyons Avenue at -grade Crossing will adversely affect Newhall Creek. an identified "blue line stream" under Fish and Came jurisdiction, and also likely under federal Fish & i'ilcilifc jurisdiction since Newhall Creek would be considered to be "waters of the t"nited 12.17 States." to accommodate this Crossing and its required elevation change to be at -grade, Newhall Creek would need to be bridged and channeled. Newhall Creek is a natural highway for wildlife, both large and small, including deer, cougars, bohcats, coyotes, skunks, opossums, rabbits, mice, squirrels, snakes, lizards, raptors, owls, turkey vultures, road runners and other species. The local oak trees are also highly protected under Santa Clarita's ordinances; changing ] 12.18 the water flow will be a threat to many of these cherished denizens, which has to be evaluated. There are many City -built hiking and equestrian trails in the area. Changes to the creek bed will 12.19 affect these crossings and uses. The proposed at -grade Lyons Crossing will affect the ultimate flow of the Santa. Clara River, of which Newhall Creek is a tributary. Full current hydrology studies must be conducted 12.20 to determine the capacity status of all drains, channels and related facilities. Topic 5: Cultural Resources The historic Old Jail building in Santa Clarita is a cultural icon that will be threatened 12.21 with the ramping up of Lyons Avenue to make it an at -grade railroad crossing. Topic 6: Geology The area of the at -grade crossing is a known seismically active area and subject to 12.22 liquefaction. LAW OFFICES GRAHAM + VAAGE LLP Mayor Smyth and Members of the City Council Cite of Santa Clarita October 16, 2017 Page 5 Topic 7: 1 Iazards and I la7ardous Materials San Fernando Road (now, Railroad Ave.) is approved for the transporting of hazardous materials. The area is slated for industrial development and will result in hazardous materials 12.23 crossing the railroad tracks at Lyons Avenue. 'brains will also be carrying hazardous materials. Heavy vehicle traffic congestion will increase the potentiality of vehicle interference, and thus collisions and spills. Topic 8: Hydrology FEMA studies show that much of Placerita Canyon as well as much of the area affected by the proposed Lyons Avenue at -grade Crossing and extension to Dockweiler to be in a 12.24 floodway. An EIR is required to analyze and to show how that designation will impact all traffic flow and how roads must be designed to avoid the areas of concern. A FEMA letter sent to the City dated August 9, 2013 confirms the vulnerability of Placerita Canyon to flooding. The Crawford, Multari & Clark study (April 10, 2008) indicates "Potentially Significant Impacts" to all aspects of Hydrology and Water Quality. The Lyons .Avenue Project may violate water duality standards and waste discharge requirements, affects groundwater supplies, alter the existing drainage pattern through the alteration of the course of a stream, and affect erosion or 12.25 siltation. Further, the Project may also affect the overall drainage pattern and increase runoff; causing flooding both on and off -site. This is in an area in which the City has previously warned residents in writing to pay particular attention to protecting themselves from the danger of flooding. (October 2012 letter.) Topic 9: Land Use and Planning Previously applied for/approved projects affecting this proposed Project include Master's College and Placerita Baptist Church expansions, and expansions for Our Lady of Perpetual Help 12.26 Catholic Church. The impact of the Compass Project, a high -density transit oriented development, must be weighed along with traffic from Dockwciler and Valle del Oro that previously used Newhall Avenue to access Lyons, because much of that traffic will he diverted this proposed at -grade Crossing at Lyons. The Lyons at -grade Crossing will facilitate new development which will conflict with Placerita Canyon's Special Standards District which was promised to residents and written into the UDC to maintain the rural equestrian nature of Placerita Canyon. Tlie Special Standards 12.27 District has no sidewalks, and no curbs or gutters, and special lighting must he designed to be compatible with the area. Such potential development must also be anticipated and evaluated. Topic 10: Mineral Resources The area served by the proposed at -grade Crossing is adjacent to an oil production area. 12.28 whose trucks will traverse the Crossing. LAW OFFICES GRAHAM • VAA,GE LLP Mayor Smyth and Members of the City Council City of Santa Clarita October 16, 2017 Page 6 Topic 11: Noise The design and construction of the proposed at -grade Lyons Crossing, including the lowering of' some of the ridgelines called for in OVOV, would allow more noise from trains and traffic to penetrate the entire area. The Crossing remove or reduce some of tlic existing physical barriers to noise. The area would clearly become a traffic "hub" if the Lyons Crossing were approved, as it would connect with other major roads throughout the City. The Lyons Avenue 12.29 at -grade Crossing would carry the highest crossing traffic volume in the Santa Clarita Valley With the possibility of five at -grade Crossings (Newhall Ave., Market St., Lyons Ave... 13th St., and Circle J) in a two-mile stretch, train whistles will sound for an cxtendcd period of time every time a train passes through town at all hours of the day and night which will be a significant disturbance to broad swaths of the community. fopic 12: Population and housing OVOV has proposed to induce substantial population growth both directly and indirectly, all of which will be using the at -grade Lyons Crossing. Directly, development of' the property adjacent to the Lyons Crossing will increase dwelling units by 150% (plus the approved 12.30 Compass ProJect), may add 500,000-700,000 square feet of commercial industrial space, may allow for a hotel/spa, will aIIow 40,000-50,000 square feet of new local retail, and add (a proposed) additional elementary school. Indirectly, the resulting growth will create a new traffic hub that will adversely affect a long -existing rural equestrian neighborhood, and will displace some of its existing homes and local businesses. Topic 13: Public Services ']'he proposed Lyons (Tossing would be a traffic hub which could impede response time 12.31 for fire, sheriff, and other emergency vehicles. The resulting proposed new development would further increase demand and need for those services. Topic 14: Recreation Placerita Canyon is a rural equestrian area with a large active facility hosting frequent regional horse shows. A second equestrian facility is planned, increasing the amount of horse 12.32 trailer traffic across the railroad crossing. Santa Clarita's trail system has many existing paths in Placerita Canyon and more planned. These accommodate hikers, bicyclists, and equestrians, all of whom would access the area by the at -grade railroad Crossing. Topic 15: Transportation A second rail line has been constructed in the area, confirming the demand for additional 12.33 rail traffic. Additional train traffic can be expected from the proposed feeder lines for LAW OFFICES GRAHAM • VAAGE LLP Mayor Smyth and Members of the City Council City of Santa Clarita October 16. 2017 Page 7 ExpressRail. The effect of the High Speed Rail Project on existing facilities is yet unknown but I 12.33 must be anticipated. The Lyons Project analysis must fully account for proximity to the Newhall Metrolink Station. F'very Metrolink train will bring, traffic to a halt whether or not it stops at the station, 12.34 and the frequency will be greater during peak hour vehicle traffic. When a train is stopped at the Newhall Mctrolink Station, the arms will he down for an extended time. Placerita Canyon Road is a private road located wildfire/fire hazard gone, and is gated on its eastern end. While the gate is supposed to be open during emergencies, that has not always 12.35 been the case, requiring residents to cross over the railroad. In summary, the Lyons Avenue Project I)FIR has not met CEQA requirements. It has not properly evaluated the Dockweiler Project in conjunction with the Lyons Prgject. The Lyom, 12.36 Project creates its own safety° hazards, and will create a traffic hub that connects other major streets, but that foreseeable impact has not been fully evaluated. The alternative crossing at 130' Street will never obtain PUC approval, and is also inadequate. `lhc Market Street crossing is t}�c ] 12.37 only alternative which lessens but does not eliminate the major environmental burdens which adversely impact the rest of the community, and especially I'lacerita Canyon. ] 12.38 Yours very) , K. CRAIIAM cc: Client AKG;'fs Enclosure ARTHUR L. KASSAN, P.E. Consulting Traffic Engineer 5105 Cimarron Lane Culver City, CA 90230 (310) 558-0808; Fax: (310) 558-1829 May 26, 2010 Robert P. Silverstein, Esq. The Silverstein Law Firm 215 North Marengo Avenue Third Floor Pasadena, CA 91101 Subject: Lyons Avenue At -Grade Railroad Crossing Santa Clarita, CA Dear Mr. Silverstein: I have reviewed the Lyons Avenue At -Grade Railroad Crossing Stage I Draft EIR, dated March 2010. I concentrated on the traffic and transportation issues, but I also reviewed the remainder of the text for background purposes. Following are my comments. 1. The document reports on the analysis of the first stage of a two -stage project that, in its second stage, entails the extension of an arterial street and the development of 213 acres of vacant land. As such, the analysis is incomplete, because the potentially significant impacts of the second stage of the project are ignored. The Draft EIR (DEIR) is focused on the analyses of the impacts of the relocating the existing railroad crossing east of Railroad Avenue from its current location at 13"' Street to new location as the extension of Lyons Avenue. However, one of the primary objectives of the relocation is to "Provide greater connectivity between Downtown Newhall, Placerita Canyon, The Master's College, and the residents that live along Dockweiler Drive." [page 7.0-21 Fulfilling that "connectivity" objective will result in significant impacts on the North Newhall area by opening the area to the opportunity for substantial new development, on Dockweiler Drive because of increased traffic flow through the residential sections of the street, and on Lyons Avenue because of increased attraction as a route between the eastern and western parts of Santa Clarita and the two freeways that serve the city. The DEIR recognizes that by saying "... the two components of the project (CPUC approval [of the new railroad crossing], followed by Specific Plan and roadway [Dockweiler Drive] extension) are interdependent The crossing change cannot be done without the development of the NNSP [North Newhall Specific Plan] area." [page 2.0-31 Yet, the effects of one part of the project upon the other and upon the greater environment must be postponed according to the DEIR. "The City will prepare the Stage Robert Silverstein, Esq. May 26, 2010 Page 2 II document upon receipt of a project application from deemed completed by the Community Development Department." [page 2.0-3] That statement is made even though enough is known about the NNSP that it can be described in great detail as to the proposed uses — residential units, research and development, offices, community retail, and a hotel — and as to the exact numbers of units and the exact floor areas of the non- residential components. [page 5.6-5] Certainly, that s enough detail that the specific impacts of that development and of the extension of Dockweiler Drive could be considered as part of a DEIR of the entire "interdependent" project. Postponing consideration of the difficult issues that will arise from the Stage II components may lead the reader to infer that the project proponent is avoiding addressing potentially significant problems for the developer of the NNSP. The fact that the probable developer of the NNSP is funding the preparation of the EIR can only strengthen the inference. [City Council action on May 26, 2009, authorizing the professional services agreement to prepare the EIR. "EIR preparation costs will be borne by the co -applicant, Casden Santa Clarita, LLC," according the City Council Agenda Report. The City of Santa Clarita is the other co -applicant of the project.] 2. As currently configured, the Lyons Avenue railroad crossing will not connect to any existing street east of the railroad in "Stage I" of the project. Therefore, the crossing will not be functional until a street connection — purportedly the extension of Dockweiler Drive — is complete, and the analysis of the railroad crossing should not be separated from the analysis of the street extension, as they are "interdependent." State and federal agencies that are evaluating a road project apply the standard of "independent utility." That is, they determine whether or not the reposed road improvement will function on its own without further construction of another road proj ect. As illustrated in several DEIR figures, the eastern extent of the Lyons Avenue railroad crossing project will be the western edge of Newhall Creek. [Figures 2.0-4, 5.5- 5, and 5.6-1] The new crossing cannot function until it is connected to the rest of the street network. As currently proposed by the City, the extension of Dockweiler Drive is the connection. The "two components of the project... are interdependent. The crossing change cannot be done without the development of the NNSP area." [page 2.0-3] As stated in the DEIR, the existing 13`h Street railroad crossing is not proposed to be closed to traffic until Dockweiler Drive has been extended to connect to the new Lyons Avenue railroad crossing. "Upon approval by the California Public Utilities Commission (CPUC) and the completion of the future extension of Dockweiler Drive as a part of the North Newhall Specific Plan (NNSP) Stage II EIR, the existing 13`h Street at -grade rail crossing would be abandoned." [page 3.0-4] Also, "Upon completion of the future Dockweiler Drive extension and the at -grade rail crossing at Lyons Avenue, the existing 13`h Street at -grade rail crossing would be closed." [page 5.6-22] Robert Silverstein, Esq. May 26, 2010 Page 3 The Southern California Regional Rail Authority (SCRRA), a five -county joint powers authority created by the CPUC, has passed Resolution98-21, which requires that a member agency that is requesting a new highway -railroad crossing also request the closure of an existing highway -railroad crossing, "so there will be no net increase in the number of highway -railroad crossings on SCRRA's commuter rail system." [page 5.6-17] Therefore, the Lyons Avenue crossing could not be opened until the 131h Street crossing can be closed. In the meanwhile, the Lyons Avenue crossing will have to be made unusable by the installation of barricades or similar methods t block traffic flow. There is no substantive explanation of why the proponents of the project are in a hurry to produce the DEIR for the Lyons Avenue railroad crossing when its functionality is entirely dependent on the connection to Dockweiler Drive, and the EIR process for the extension of that street has not yet begun. When will the street extension be constructed, so the new crossing could be opened to traffic? 3. There is no indication in the DEIR that the extension of Dockweiler Drive will be feasible despite several severe physical impediments and substantial impacts on the environment along the existing street. Currently, Dockweiler Drive extends from a tee -intersection with Sierra Highway, near the southeastern limits of the City of Santa Clarita, to a short distance west of Leonard Tree U- Lane, a total length of approximately 9/1 Oths of a mile. Beyond the end of the paved roadway west of Leonard Tree Lane, the extension of Dockweiler Drive is an unpaved, narrow dirt track, less than two lanes wide, along a narrow piece of land that juts out toward the west from the existing residential neighborhood. On either side of the dirt road and at its western end, there are steep embankments to the valleys below. Both the side embankments and the valley to the west appear to be several hundred feet in height. The area on top of the land that is currently occupied by the narrow dirt road is not wide enough to accommodate the proposed street extension. Therefore, there will have to be substantial importing of earth and, perhaps, construction of large retaining walls to fill in the existing side embankments and provide an adequate "platform" upon which to build the new street. Extending the road toward the west across the valley may require further earth fill and retaining walls, or, perhaps, an expensive bridge with no connections to the land and developments on either side. Alternatively, Dockweiler Drive could be extended downward into the valley by way of relatively steep roadway grades and side slopes. Either method of extending the street will require substantial earth -moving that may make it impracticable to build the extension. "According to the Santa Clarita General Plan, Dockweiler Drive is designated as a secondary highway." [page 2.0-19] "The approved Master's College Master Plan amended the Circulation Element to define and re -designate Dockweiler Drive as a four lane secondary highway." [page 10.0-2] Currently, "Dockweiler Drive consists of one lane in each direction with a landscaped median and is used as the primary access to single-family and multiple -family Robert Silverstein, Esq. May 26, 2010 Page 4 residences along Dockweiler Drive." [page 2.0-19] Essentially, the existing street is acting as a Local Residential Street with parking permitted at all times at both curbs. The parking is used extensively throughout the day. The two roadways (including the parking) are each 25 feet wide, and the landscaped median that separates the roadways is 13 to 14 feet wide. Connecting that residential neighborhood street to a secondary highway will change the character of the street and the residential neighborhood that it serves. The proposed Dockweiler Drive -Lyons Avenue -Pico Canyon Road artery will provide a continuous east -west through route from substantially west of the Golden State Freeway (I-5) to the Antelope Valley Freeway (SR-14), an uninterrupted length of more than five miles. Obviously, such a route connecting several of the City of Santa Clarita's communities and the two freeways will attract substantial volumes of through traffic. The existing section of Dockweiler Drive functions as a residential neighborhood street now, because the only development it serves is residential, and there can be no through traffic from other communities, because the street ends at Leonard Tree Lane. Residents who -are used to a relatively peaceful street environment will experience increased noise, vibrations, and potential safety hazards resulting from the intrusion of through traffic when Dockweiler Drive is connected to Lyons Avenue. There is no assurance that the existing street section, with only one traffic lane in each direction, will accommodate the substantial increases in traffic flows throughout the day, and particularly during the peak commuter periods. There may come a time when it will become necessary to eliminate the on -street parking on Dockweiler Drive in order to provide a C-second lane in each direction to match the four -lane divided configuration of the proposed secondary highway that will be built as the street extension toward the west to connect to Lyons Avenue. That elimination of curbside parking will cause a hardship to the residents along the existing section of the street who are used to the availability of on -street parking along Dockweiler Drive through their neighborhood, particularly those who have garages that will accommodate cars but not trucks. Is the City contemplating widening the existing segment of Dockweiler Drive to provide two lanes in each direction while retaining the parking? Adequate widening would essentially eliminate the landscaping, including mature trees, in front of many of the residences that line the street. Will sidewalks be provided along existing Dockweiler Drive to accommodate the school children and other pedestrians where there are no sidewalks now? Considering the increases in traffic volumes and vehicle speeds that will accompany the continuity of the street, the pedestrian safety issues must be addressed before connection can be approved. The City has recognized the potential for through traffic problems on Dockweiler Drive after its extension to Lyons Avenue. "[Tlhe City plans to incorporate traffic calming measures on Dockweiler Drive to limit cut -through traffic to and from Sierra Highway to maintain the residential character of the existing Dockweiler Drive." [page 5.6-6] This is an admission that the proposed connection of the two streets is a flawed Robert Silverstein, Esq. May 26, 2010 Page 5 plan that will immediately lead to significant impacts on the environment in the existing residential neighborhood. In traffic engineering, it is not typical practice to apply traffic calming measures to any arterial street, such as the secondary highway. For any arterial street, the primary purpose is the safe and efficient movement of traffic. The installation of traffic calming devices, with the sole purpose of slowing and making the street unattractive to through traffic flow, is at cross purposes with the secondary highway designation. Either the street will be a secondary highway accommodating substantial traffic flows or it will remain a residential neighborhood street providing access and parking for the homes adjacent to the street and a safe, attractive environment for the residents. The street cannot perform both functions effectively. If Dockweiler Drive is not to become a through traffic route, why not build the new section of the street to be discontinuous from the existing residential section? That is, start the new section in the valley near The Master's College and west of the neighborhood, and then extend it westward to the Lyons Avenue railroad crossing. That new section would serve the college traffic and provide connectivity to downtown Newhall for the NNSP development, which is one of the goals of the crossing project, while protecting the existing residential neighborhood. A discontinuity between existing Dockweiler Drive and the proposed secondary highway extension would have several advantages: 1) it would protect the existing residential neighborhood from through traffic; 2) it could be built without the substantial earth -moving costs and environmental impacts that will result from a connection to the existing Dockweiler Drive; and 3) the extension could be named Lyons Avenue to remove driver confusion that would result from a change of street names for the new section east of the railroad. There would be one disadvantage to the street discontinuity: drivers traveling from and to the NNSP development and other nearby developments could not use the extension as an access route to/from Sierra Highway and the Antelope Freeway. That would be a large component of the undesirable through traffic in the residential neighborhood that would not materialize if the discontinuous design is implemented. 4. One of the stated primary objectives of the Lyons Avenue railroad crossing is the improvement of traffic safety. But, the 13th Street crossing has been relatively safe, and its safety could be further enhanced with modernized traffic control devices. Every traffic accident is regrettable, especially those that could have been prevented by a better physical condition or better application and operation of traffic control devices. "A review of the United States Department of Transportation (U. S. DOT) - Federal Railroad Administration traffic report indicates a total of four train -auto accidents have been recorded at the 13th Street at -grade rail crossing since December 1977, Robert Silverstein, Esq. May 26, 2010 Page 6 including 1 fatality." [page 5.6-9] The DEIR includes the actual accident reports for each of the four accidents as part of the appendix to the Overland Traffic Consultants, Inc. report, which itself is an appendix to the DEIR. Following are data for the four accidents. Date & Time of Arrirlrnt 12/03/1977; 5:35 p.m. 12/06/1990; 10:00 a.m. O1/16/1999; 3:30 p.m. 07/23/1999; 2:32 p.m. Highway Vehicle Driver Artinn Stalled on crossing Stopped on crossing "Drove through gates" Stalled on Crossing Number of Number of People Killed People Injured 0 0 0 0 1 0 (83-year-old driver) 0 0 After the first accident in 1977, it was 13 years until the next accident in 1990. Then, it was more than eight years until the next two accidents, both in 1999. Since the fourth accident (July 1999), there have been more than ten years with no railroad crossing accidents at 13th Street. That current record is better than the experience cited in the DEIR as exemplary for "the crossing at Ruether Avenue where only one accident has been reported in more than 10 years of operation." [page 5.6-29] In three of the four accidents, there was no one killed or injured in either the highway vehicle or on the train. In the one fatal accident, there was probably driver error, as the vehicle was driven through or around the crossing gates that were operating properly. Those four accidents over a 32-year period are not sufficient to warrant the relocation of the 13th Street railroad crossing to Lyons Avenue for safety considerations. All four accidents could have been prevented by the installation of better traffic control devices, that is, the same devices that are being proposed in the DEIR for the relocated crossing and are described as "Sealed corridor safety enhancements". [page 5.6-29] The proposed measures for the Lyons Avenue crossing include "four -quadrant gates to eliminate all travel across the tracks when the signals are activated, ... raised central medians, ...and video cameras to monitor operation of the at -grade rail crossing..." [pages 5.6-29, 30] If those or similar measures had been installed at the 13th Street crossing, all four accidents, especially the fatality, would likely have been prevented. It would be interesting and useful to the public and the decision makers to have a comparison between the experience of four railroad -highway vehicle accidents in 32 years (1977 through 2009) at the existing 13th Street railroad crossing versus the highway vehicle accident history at the nearby Lyons Avenue/Railroad Avenue intersection during the same 32 years. Although we do not have the accident history for the street intersection, the City staff has access to it, and they should be requested to provide the street intersection accident history for comparison purposes. 5. The DEJR conclusion that the proposed railroad crossing relocation project will not be "growth inducing" is contradicted by other statements in the DEIR. Robert Silverstein, Esq. May 26, 2010 Page 7 According to the DEIR, "Generally, a project may foster spatial, economic, or population growth in a geographic area if it meets anyone of four criteria that are identified below: • Removal of an impediment to growth (...the provision of new access to an area)..." [page 10.0-1] Also in the DEIR, "Growth in an area may result from the removal of physical impediments or restrictions to growth. In this context, physical growth impediments may include non-existent or inadequate access to an area or the lack of essential services." [page 10.0-2] The DEIR discussion in Section 10 continues by describing several amendments to the General Plan Circulation Element that called for the extension of Dockweiler Drive, as a four -lane secondary highway, and its connection to Lyons Avenue. The objective of that street project would be "...to allow for traffic flow from Sierra Highway to Interstate (I) 5 Freeway." [page 10.0-2] Then, the DEIR authors come to the following conclusion: "This project [relocation of the railroad crossing is not growth inducing as the proposed project would facilitate circulation within an infill area of the City and does not encourage growth into the area. As such, the proposed project would not be considered growth inducing." [page 10.0-2] That conclusion seems to be based on the theory that a street that is shown in the Circulation Element, although not actually built, can be considered as if it actually exists and is usable by traffic. The conclusion is completely contradicted by a statement in the "Alternatives" section of the DEIR. In describing "Alternative 1 - No Project Alternative", the DEIR states, "The Stage II North Newhall Specific Plan (NNSP) would not occur" if the railroad crossing relocation does not take place. [page 7.0-10] The NNSP is the planned development of "809 dwelling units plus a commercial land use component of approximately 176,500 square feet (sf) of research and development uses, 186,500 sf of office uses, 40,000 sf of community retail, and a hotel of 70,000 s£" [page 5.6-5] Therefore, a substantial and, perhaps, the primary purpose of the railroad crossing relocation (Stage I) project is to facilitate the development planned for the NNSP (the Stage II project). Contrary to the DEIR conclusion, it should be concluded that any street improvement project that will make it feasible to build such an extensive development should be considered growth inducing, and the relocation of the railroad crossing meets that definition. 6. The stoppage of trains at the nearby Metrolink station may impact traffic flow at the proposed Lyons Avenue railroad crossing. "The nearest rail station to the proposed project is located at Railroad Avenue and Market Street approximately 0.2 mile south of the Lyons Avenue and Railroad Avenue Robert Silverstein, Esq. May 26, 2010 Page 8 intersection (project site)." [page 3.0-71 The station is approximately 1,000 feet south of the proposed railroad crossing. Will trains stopped at the station result in the crossing gates and flashers remaining activated for the duration of the stop? If so, the crossing would not be usable for highway vehicle traffic during those stops, which will be most significant during the morning and afternoon commuter traffic and commuter train peak periods. If it can be documented, with technical information about the operation of the crossing gates and signals, that there will be no interference with Lyons Avenue traffic flow as a result of stopped trains and the operation of the crossing protection devices, that should be presented clearly in the DEIR. In either case, the concern that has been expressed by many Santa Clarita residents should be specifically addressed in the DEIR. 7. The analysis of the construction impacts of the project does not address the most important issue - the detouring of traffic from Railroad Avenue and Lyons Avenue while both streets are being elevated and widened. The railroad track east of the Lyons Avenue/Railroad Avenue intersection is approximately 4 to 5 feet higher than the existing surface of the street intersection. To achieve an at -grade crossing of the railroad, substantial sections of both streets will have to be elevated - Lyons Avenue from Main Street to Railroad Avenue, and Railroad Avenue from approximately 91h Street to north of llth Street. In conjunction with the elevation of the two streets, both streets will be widened, and new sidewalks, retaining walls, and improvements to the adjacent properties will have to built. During the time that the two streets are being re -constructed, traffic that currently uses those streets will have to be detoured to other streets. For example, Lyons Avenue traffic heading to the existing 13th Street railroad crossing may be forced to use Walnut Street and 12th Street to bypass the construction area. North -south traffic currently using Railroad Avenue may have to use Main Street, Walnut Street, or Newhall Avenue. The DEIR does not address the significant issue of traffic that will have to be detoured during the substantial street re -construction period. [page 5.6-22] The only construction -related issues addressed are the movements of large construction equipment and the commuting of construction workers, both of which are significant issues, but will be far less disrupting than the closure of two arterial streets to all traffic during the re- construction of both streets. The construction -related questions that should be addressed by the DEIR include the following. 1) Will the streets that are available for detour routing have the capacities to carry the substantial volumes of additional traffic? 2) What will be the impacts on developments, particularly downtown businesses, adjacent to those streets? 3) How far from the construction area will drivers route themselves to the detour streets in order to minimize congestion and delay near the construction area? 4) What will be the impact of construction detouring and related congestion on access to and use of the Metrolink station that is located only two blocks south of the beginning of the Railroad Avenue re- construction section? Robert Silverstein, Esq. May 26, 2010 Page 9 8. The requirements of the construction plan mitigation measure are confusing and contradictory. Mitigation Measure MM 5.6-1 begins with the requirement that "The applicant shall develop and implement a construction traffic control plan (CTCP) prior to the start of construction." [page 5.6-26] Some of the conditions for the plan are as follows: • "The CTCP shall be submitted to, and approved by, the City Engineer." [emphasis added] • "In areas where traffic control necessitates, the contractor shall provide, post and maintain 'No Parking' and 'No Stopping' signs, as directed by the Director of Public Works." [emphasis added] • "The locations of all signs shall be determined in the field by the County Engineer in conjunction with the contractor." [emphasis added] Are those requirements meant to apply to three different people? Or, are the City Engineer and the Director of Public Works the same person? And, why is the County Engineer involved in performing a single task during a construction project that is entirely within the City of Santa Clarita? In summary, my recommendation is that further study be given to the feasibility of connecting Lyons Avenue to Dockweiler Drive and to the practical problems and environmental impacts that will result. As part of that study, there should be serious consideration of my recommendation to extend Lyons Avenue to the vicinity of the Master's College but not connect it to the existing residential section of Dockweiler Drive, as discussed on pages 4 and 5 of this letter. Then, after an agreeable program has been set forth, a single DEIR should be prepared to analyze the impacts of the relocation of the railroad crossing, the extension of the arterial street, and the extensive development proposed for the NNSP area, particularly the Casden project and the Compass Blueprint Project. At that time, sufficient duration should be provided for the public to review the complex, multi -faceted project that is the total of all of the issues that should be considered as an "interdependent" project. I would be pleased to discuss my comments with you, with members of the public, and with the staff and officials of the City of Santa Clarita. Very truly yours, Arthur L. Kassan, P.E.

My husband and I, 30 year residents of the Canyon, support the extension of Dockwieler so that Masters College can safely expand. But we feel that a connection to Market is much better than Lyons Avenue. -A RR crossing already exists at Market. and that area is a transportation hub. The grade for the Road, and creek crossing is much easier than Lyons Avenue. 14.1 -The RR crossing at 13th could remain open, allowing Canyon residents to maintain their primary exit. The crossing could be improved at a later time, as future development of the plot of land off 13th is developed. -Bringing traffic into downtown Newhall at Market, encourages drivers to become familiar with the shops and restaurants in the area, that the city has worked so hard to promote. Thank you for this opportunity to offer our opinion.

I have 2 horses on the property. My home is very special to me. With that said, I believe the city has continually sidestepped the intention of the special standards district. The new Revelo project and mixed use being introduced into the neighborhood have promised to negatively change the neighborhood forever. This Dockweiler Extension will further the decline. The proposed Lyons crossing was always a bad idea. It would have necessitated raising Railroad Ave and part of Lyons, dumped lots of traffic into the train track crossing and the Railroad/Lyons intersection, and would have created a traffic nightmare for this community. Alternative 2, the extension of Dockweiler to 13th Street is only a little better (and is the preferred by the DEIR, less encroaching alternative). Both alternatives will further erode the rural equestrian feel of the area, and of course, no one would want to ride their horse anywhere near the road. It will increase the traffic flows through our community to a shared track crossing. Your traffic study and its counts are 5 years old, and do not truly reflect the total picture of the traffic in this neighborhood. Long lines when there is a train! Long lines when church gets out (or before church)! These will be exacerbated by more trains and the new development, which most likely (no matter what your counts say) will double the traffic flows across the train tracks. Improvement at the 13th St. crossing will barely improve the built out situation without adding lots of Dockweiler traffic. I am suggesting two outlets; an improved, widened, safe 13th St crossing for Placerita Cyn residents and the new mixed -use development, and a smaller connection to Railroad at Market St. It is possible if a gentle curving road is nested into the hillside. It will dilute the amount of traffic going onto the roadway at one time. And, it will protect the Special Standards District of Placerita Cyn, and its residents from extra traffic. I am not sure why it was dismissed and not included as an alternative when it truly can be accomplished. Of course, it might decrease the total flow of traffic on 15.1 15.2 15.3 15.4 HO 15.6 Dockweiler, and although you might not like that, it is the only safe way to have an extra traffic connection and preserve the safety of the people who live on Dockweiler. That community needs protection too. There is an affordable housing crisis, and the homes along Dockweiler and below are both moderate and lower income housing. Sometimes it takes a roommate or two to afford the rent. There are no sidewalks, and no place to park extra cars other than the street, so removing the lane of parking for widening the road is out of the question. Thank you for your consideration of my suggestions. Sandra Cattell 21648 Oak Orchard Rd, in Placerita Canyon Newhall, CA 91321 15.6 COMMENT LETTER No. 16 From: Jim Coffey [mailto:Jim@CORElectric.net] Sent: Monday, October 16, 2017 10:27 AM To: Mike Hennawy; Paige Coffey Subject: Dockweiler extension and Placerita Canyon Road Good morning Mike. I'm writing you with my Wife in copy to express our opinion of the pending Dockweiler extension in general, and as it relates to both Placerita Canyon Road and the Placerita Canyon neighborhood in general. Both Paige and I are 50 year residents of mostly Newhall, the last 17 of which have been in Placerita Canyon at our current home located at 21551 Placerita Canyon Road. We love our Special Standards ❑istrict community, and like our neighbors there our goal is to protect it from any negative impact to ourselves or anyone else who created a home there. We're aware of the multiple Dockweiler extension options on the table, one of which I name as an option even though the City seems not to recognize it as one. We are very optimistic about Masters traffic to and from Dockweiler, as it should lighten the congestion on Placerita Canyon Road which is a source of aggravation often. That said, our formal opinion and request toward the ❑ockweiler extension is as follows: New Lvons crossina and connection to Dockweiler with sours to adjacent and/or adjoining streets affected. We are strongly opposed to this in any form. The crossing is far too costly and will negatively affect Old Town Newhall. With Newhall Avenue and Via Princessa pending, there is no reason to open such a major flow of traffic between Lyons and Sierra. Such traffic will negatively inhibit Placerita Canyon Residents in and out of the west end of the neighborhood. Expanded 1311 Street crossing with connection to Dockweiler and associate connection(s) to 1211 Street, Placerita Canyon et al. While we are less opposed to this than the new Lyons crossing we are opposed to it again because of the traffic it will bring to the west end on our neighborhood. In the end, with this option our now overcrowded 13`h Street crossing aka west end entry/exit will WON 16.2 be worse off than it currently is even though widened. The "shortcut" created by this connection of Sierra Highway to 1 3t" Street will be a traffic nightmare, especially when any Ravello or similar project is built out. As one of only two canyon exits, we're already in danger of getting out quickly and safely during an emergency. No Dockweiler extension past connection to Masters. We would be in favor of this, since the true goal of any Dockweiler extension should be to gain proper access and traffic flow in and out of Masters' campus as necessary to avoid negative impact to the Placenta Canyon residents and neighborhood. Dockweiler connection to Market Street. We are in favor of and request this option. We call this an option because it is, even though it would require a few steps back to realign the current approved Dockweiler extension. As a good neighbor should, Masters should allow such a realignment as long as it doesn't negatively impact their new entry/exit. This option will allow direct access to Old Town Newhall for Masters, as well as provide an additional general entry and exit to Old Town Newhall from an additional point of access. Everyone benefits from this option, and other than some additional preconstruction prep and process work there is no downside. Thank you for receiving our formal comments and opinion. Kindly acknowledge your receipt of this and formal entry into the EIR documents.

It is attached. Please read it and distribute it to the various departments and personnel involved with this proposed project. I am aware that my position is not fully in sync with the PCPOA, but I believe my opposition to this project has merits and hopefully I would have the 20.1 opportunity to discuss or communicate my concerns with the city officials and also present my position points at any public hearing on this matter. In anticipation of your consideration, I thank you. Respectfully, Tony Matthess Anthony Matthess Office Fax: (661) 253-1393 Cell: (661) 816-0663 Home: (661) 254-3750 email: acmatthess(a�gmail.com COMMENT LETTER No. 20 September 25, 2017 The Honorable Members of the City Council of the City of Santa Clarita Ken Striplin, Manager of the City of Santa Clarita Tom Cole, Director of Development The Dockweiler Extension — WHAT'S THE POINT! Why is the city fixated on another "east -west" connection at this location? Is it simply because it was in the General Plan to make this happen? If that is the case, we need to amend the General Plan before we build Dockweiler, as a route to nowhere, or the Santa Clarita Parkway. 20.2 The blatant fact is that we already have an east -west connection. It's Newhall Avenue! If Dockweiler is an east -west connection, so is Newhall Avenue. The absurdity of building and using Dockweiler is that Dockweiler and Newhall Avenue parallel each other and are only one-half mile apart. The positives of using Newhall Avenue are the following: • It is already built. Newhall Avenue extends and/or starts at an existing freeway an and off ramp. Newhall Avenue does not go through any residential neighborhoods. Newhall Avenue does not cost the city anything. The negatives of using Newhall Avenue are zero. The only positive of using and building Dockweiler is that it may be a better entrance and exit to Masters' College future building expansion, which would be in addition to an existing route to Newhall Avenue already planned by the college. It can be argued that it provides a faster route to the northern part of the east side of the Santa Clarita Valley. However, this is highly debatable as Newhall Avenue provides a north -south freeway on -ramp to this portion of the eastern portion of the Valley, which may take the same amount of time, or at worst approximately the same amount of time. The negatives of building and using Dockweiler as an east -west route are the following: • The cost of building and maintaining a new road. Some costs, but not all, include the "mitigation" measures for 131h street, the railroad crossing upgrades, Placeritos, and Placenta Canyon, the road and signal modifications on Railroad Avenue to enable north and south bound traffic proper access to 13th street. • The road does not serve any benefit, as its primary function would be for the east to the west traffic. However, this route ends at Sierra Highway, with no freeway on or off -ramp access. Traffic traveling south from Dockweiler would turn south and continue on Sierra Highway to the Intersection of Newhall Avenue and Sierra Highway. Ironically, this is the same terminus as the Newhall Avenue route! • There would be very little benefit for traffic that wanted to travel north from the intersection of Dockweiler and Sierra Highway, as the distance from 131h street to Dockweiler to Sierra Highway is greater that the distance from 13`" Street to the intersection of Newhall Avenue and Sierra highway. • Repercussions for and from the community for making the land at the intersection of 13th Street and Railroad Avenue available for large scale development would be egregious. As a case in 20.3 point, when the city was considering a Metro Link station at this intersection it was deemed untenable and not in the best interest of the community or Newhall or Placerita Canyon. Additionally, a large scale development's traffic impact on this portion of entrance to Dockweiler would make this an F grade road and intersection. • The importance of Placerita Canyon's rural nature and the preservation of one of the last symbols of Newhall's history were confirmed with the establishment of a Special Standards District by the City, which states: o The purpose of the Placerita Canyon special standards district (PCSSD) is to protect, maintain, preserve and enhance the secluded, rural equestrian character of the community, to enhance the community's unique appeal and to help mitigate the cumulative impacts of residential development. Additionally, it is the purpose of these special standards to ensure that new and expanded structures are compatible with the characteristics of surrounding single-family residential neighborhoods, and protect the light, air, and privacy of existing single-family residences from negative impacts. These standards are also intended to ensure reasonable access to public riding and hiking trails, and to minimize the need for installation of infrastructure such as sewers, streetlights, concrete sidewalks and concrete flood control systems that would alter the community's character, while providing for adequate drainage and other community safety features. • This route and future mass development of this area of the Canyon is contrapositive to the preservation, and the city's original intent, for the community of Placerita Canyon. 20.3 20.4 • No study exists as to the importance or need to build a secondary route to Sierra Highway at this location at this time. • It does not benefit the community of Valencia or the east side of the Santa Clarita Valley, which 20.5 presently utilizes Newhall Ranch Road and Soledad Canyon Road. So, what is the solution, and why did the EIR not include an alternative route in their report? The solution, if needed at this time, is to build that portion of Via Princessa from the existing terminus of Via Princessa (in circle J Ranch), to Golden Valley Road, at the future and planned intersection of Via Princessa and Golden Valley Road. The benefits of this route are as follows: • It adheres to the General Plan as the planned major east west connection for the valley • It has an existing bridge crossing spanning Railroad Ave. and the train tracks. • It serves the communities of Valencia and Newhall and the eastern communities of the valley, including Vista Canyon and most developments in that area. • The cost of this road will be repaid by future developers, as mandated in their Conditions of Approval. • The distance of connecting from the present terminus in Circle J to Golden Valley Road is less than the distance from 13'h Street to the terminus of Dockweiler (1.2 miles to 1.5 miles). • Will lessen the traffic impact on Railroad Ave., Newhall Ave and Soledad Canyon. The negatives of building this route are as follows: • None, as it is the planned major east -west connecter route of the General Plan, evidenced by the completed construction of the Wiley Canyon Bridge. Why didn't the EIR include this alternative in their report? I don't know. Nothing exists as to why a second route at the Dockweiler location is needed at this time. Additionally, the EIR did not mention Newhall Avenue as an alternative to Dockweiler, nor did they mention Via Princessa. Everything should stop until a full analysis, with community participation, of constructing a section of Via Princessa is completed: as well as an in depth study of why we need an additional east - WIN 20.7 west connection at this time paralleling Newhall Ave COMMENT LETTER No. 21 From: Anthony Matthess racmatthess@gmail.com> Date: October 3, 2017 at 6:33:46 PM MDT To: Ken Striplin <KSTRIPLIN@santa-clarita.com> Cc: Robert Newman <RNEWMAN@santa clarita.ccm>, Mike Hennawy <MHENNAWY@santa-clarita.com>, Carla Callahan <CCALLAHAN@santa-clarita.com>, City Council <CityCouncil@santa-clarita.com> Subject: Re: FW: Dockweiler Extension Dear Ms. Callahan: In response to Ken Striplin's letter to me, I want to express my gratitude for having the opportunity to put forward my objections to the Dockweiler Extension at this time. I have lived in the canyon for over 40 years; 31 in Placerita Canyon. I am a past Board Member of the PCPOA, and with the help of Buck McKeon, was personally instrumental in moving the proposed Metrolink Placerita station to Soledad Canyon, Rd. I have been involved in the real estate industry in Santa Clarita since 1972, including starting and owning a real estate sales company in the 70's, forming a real estate development and construction company in the 80's, entitling and building several residential and commercial developments in the Santa Clarita, and starting Valencia National Bank in 1985. The reason for describing my personal involvement in the city during my 40+years in Santa Clarita is meant to assure you that my opposition to the Dockweiler Extension is not a rant. After taking part in the community meeting held at Masters College last Thursday evening, it was evident the PCOPA board members that were there, and several of the most vocal homeowners in attendance, unfortunately spent most of their time on the minutiae of the Dockweiler Extension issue. Additionally, after meeting with several Placerita Canyon homeowners in attendance and over 20 that were not in the meeting, the "Board" is not aligned with our position, and misrepresenting the majority of the homeowners in the Placerita Canyon area. It is our position that the focus of the Dockweiler EIR does not address the merits of not building Dockweiler at this time. Those, but not all, are the following: Why should Dockweiler be built at this time? Newhall Ave is not impacted at this time and Newhall proper is built -out. Therefore, traffic from Newhall or the surrounding area of Newhall will not increase enough to warrant another east -west connection at this location at this time, Via Princessa would serve as a better east -west connection for the following reasons: o It serves the communities of Valencia, Newhall, Circle J, Valencia Town Center and other commercial and office communities of Valencia on the west side of the city. It serves the communities on the east side of the city, such as Vista Canyon, Sand Canyon Plaza, Sand Canyon, Fairoaks, Friendly Valley, developments boarding Via Princessa, Sierra Highway and Golden Valley, and the commercial developments at Sierra Highway, Via Princessa and Golden Valley, along with those traveling on the Antelope Valley freeway. The overpass of Sierra Highway and the railroad is already constructed via the Wiley Canyon Bridge. It should also be noted that very few people throughout the city, including staff at the Signal newspaper, have any awareness of the Dockweiler Extension. It is my belief that if the general public was aware that the city was contemplating building out Via Princessa, you would have thousands of people responding. In all good conscience, and for the benefit of the whole City of Santa Clarita, an El on completing the construction of Via Princessa to Golden Valley prior to building the "Dockweiler Extension" is paramount.

Please provide your comments below: To Whom It May Concern, After analyzing the DEIR for the Proposed Lyons Avenue/Dockweiler Drive Extension the following questions and concerns have sparked my attention: 1) How will all of the properties needed for the construction of the extension be obtained? Will the needed properties be completely acquired by the City of Santa Clarita, or will only the necessary portions needed for the extension be acquired, either by purchase and re -zoning property lines or leasing the needed portion of the property from the owner? 2) With the Dockweiler extension, Valle del Oro has a direct connection into Placerita Canyon. With such access, how will The City of Santa Clarita, as well as the Santa Clarita Sheriffs Station enforce and prevent a non -avoidable increase in crime rates. The current layout of Placerita Canyon allows a one-way entrance and exit, resulting in an extremely low rate of crime. However with this connection, there are multiple entrances and exits providing a higher chance of crime. When looking at recent crime maps, the neighborhood surrounding Valle del Oro has numerous incidents (including the recent Lyons Ave. road closure involving LAPD and an armed robbery suspect), while Placerita Canyon has extremely low crime reports. 24.1 24.2 3) When reading the DEIR, all options for the project are said to "avoid direct impact to Placerita Canyon". After analyzing the options, I feel that all rather provide a "direct impact" to Placenta Canyon. Whether it is from a non -avoidable increase in crime, 24.3 traffic, or the loss of the rural equestrian lifestyle that we all have worked very hard to preserve, this extension will result in a detrimental decline of a neighborhood that is proud of the historical importance it holds. Rather than focusing on increasing the size and profitability of every square inch of Santa Clarita, I truly hope the members of the City Counsel who democratically represent the people of Santa Clarita (including the residents of Placenta Canyon) will listen to, and make an educated decision regarding 24.4 this extension with the residents' concerns and opinions in mind.

It is a small beautiful area with a unique lifestyle. I am concerned with and I am AGAINST the Dockweiler Drive extension. We are constantly threatened by fires. If a passing motorist throws out a cigarette while driving on this new extension our community will be destroyed. I also think it is a waste of taxpayers money. A Golden Valley extension would make more sense. 27 The traffic that would be created at the end of our road is also a big concern. I do not fell this extension is a critical issue at this time and think there should be another solution. Thank you for reading this and I hope you make the correct decision.

I recently learned about a proposal to connect Dockweiler Drive to 13" Street, Lyons Avenue, or Market Street to decrease the traffic on Newhall Avenue. I believe that the problem isn't lying in the traffic on Newhall Avenue, it is the traffic on the 5 and 14 freeways. Many commuters that drive down Newhall Avenue are not driving to Newhall, they are driving to Valencia, Saugus, or other parts of Santa Clarita. The major intersections in Newhall are two and three lanes wide on each side while the intersections in Valencia are around six. You see a fraction of the cars driving through Newhall compared to Valencia. Newhall Avenue is the first exit off the freeway and people would rather get off to drive on side streets than sit on the freeway in stop and go traffic. My point is that possibly the traffic situation would improve if the residents in the Northern part of Santa Clarita had an easier way to commute to and from their homes. Widening the freeways or improving the off ramps near their homes would be more effective for the future and eminent growth of this city. I have lived in Placerita Canyon long enough to remember the days before the gate was installed on our street. As kids, we weren't allowed to go outside our fence at any time because the traffic was terrible and too dangerous. After the gate was installed it changed our lives completely. Placerita Canyon became a neighborhood that some of us had never experienced before. I remember looking out the window and couldn't believe when I saw people walking their dogs on the street! My dad started taking us for bike rides in the evening and that was the first time we were ever able to do that together. For once we could ride our horses and bicycles safely across the street to the little market for ice cream on a warm summer day. To this day I walk down the street with my horse and come across families on bicycles, elderly neighbors dropping off their farm fresh eggs at friends' houses, and people that I would have never even met before walking their dogs. My stand on the proposal is for the "No Build" option. To turn nice quiet residential neighborhoods into major thoroughfares with large amounts of traffic in order alleviate traffic elsewhere is unfair. It is not the responsibility of the residents to solve commuter problems and the issues should be addressed elsewhere. Every person should be able to raise their kids in a nice neighborhood without the concern of their safety. Please take this letter into consideration before moving forward with these proposals.

I have lived in this canyon for over 34 years. There is a quality of life in our canyon 30.1 that is rare and hard to find elsewhere in the city. By dumping Dockweiler, Casden, and additional Master's College vehicles into the canyon you are greatly disrupting our "quality of Life"! There are several issues I would suggest you review/re-review. 1). What is the impact of the increased population of Master's College. More students equal 30.2 more cars equal more traffic. They need an entrance/exit off of Railroad Avenue. 2). What is the impact of the studio overlay for filming in the Canyon? In addition to Melody Ranch's filming, there has been a huge increase of additional filming in the canyon. Within the last month I have been stopped on Placerita Canyon Road (the private portion) and not allowed to go through until their filming shot was done. There is an additional impact into this canyon related to traffic just from the filming traffic and this is before the possibly additional vehicles are 30.3 added from Dockweiler, Casden, and Master's. The increase in filming vehicles, trucks, van, etc. is also at a detriment to our quality of life. The oversized trucks from the studios come barreling down the canyon at all hours of the day and night. They even come into contact with the oak trees this city works so hard to protect! What is the impact of all of this additional traffic prior to you adding more vehicles if the proposed option is adopted? 3). Additionally - what is the impact of accidents on the local freeways? Well I can tell you what happens. Railroad Avenue backs up and trying to get out of Placerita Canyon takes a long time. If you add vehicles from Dockweiler, Casden, and Master's College to this scenario it will be and even larger nightmare. While everyone is always affected by traffic accidents, it is unfair to put the residents of Placerita in an even worse position. On October 5 and October 10 of this 30.4 year there were accidents of the southbound 5 freeway. Both days saw the traffic on Railroad Avenue back up and left Placerita Canyon residents waiting for multiple lights to get out of the canyon. Again everyone is affected by accidents buy this option will make it three times worse for the canyon which I don't believe is fair or the correct thing to do. There are other options that make more sense. Suggestions: I would highly recomend using the Market Street crossing. There is already more infrastructure at that intersection to handle the amount of vehicles. Cars could go left, right or straight as opposed to only having the option of going left or right with the 13th street option. 30.5 Another suggestion would be to spend our hard earned tax payer money on completing Via Princessa. Have the Casden properties connect with Via Princessa to the North and leave Dockweiler alone. If you must do something with Dockweiler have it connect at Market Street which is better able to handle the traffic. Lastly, I just would ask that you not ruin the Placerita Canyon way of life. Since this city was incorporated all I hear about is the Quality of Life that we enjoy and need to protect. Well, please practice what you preach and don't ruin our "Quality of Life"! 30.6 Thank you for addressing these issues. Linda Redmond 21107 Placerita Canyon COMMENT LETTER No. 31 From: Jeff Secor <secor6ksbcg1oba1.net> Date: September 20, 2017 at 11:15:47 PM PDT To: "Ccallahanksanta-clarita.com" <Ccallahanksanta-clarita.com> Subject: Lyons Ave-Dockweiler Extension Reply -To: Jeff Secor <secor6ksbcg1oba1.net> Mr. Callahan, We attended a meeting on September 14, 2017 held at Masters University regarding the Lyons Ave/Dockweiler Extension, along with a number of our neighbors. We appreciate you holding the meeting, but aren't really sure you came with an open mind and ears to LISTEN to what the community was saying. A very compelling question asked, that was not answered very clearly, was "Why this project at all?" It doesn't make sense to divide traffic in one area, just to bring it back together a mile or two later. Is TMU still even planning to do their previously approved plan? That is another discussion that needs to be had. We were also very disappointed that the idea of bringing Dockweiler to Market Street, which already has a large RR crossing was not readily discussed. This seems like such a natural solution. It seemed that many of the residents were more favorable toward this crossing than the other crossing options. 31.2 31.3 Another question is, who owns the property that will need to be acquired for these projects? Are there any city officials, current or past, that could potentially profit from this Extension Project by selling their land for one or another of the 31.4 projects and could that be why this is being ramrodded through? (i.e. LaureneWeste) If you have spent any time in the Canyon, you would understand what it is like already, to try and cross at 13th Street after a train (of which there are many during the day). It is not uncommon for traffic to be backed up to Placeritos and beyond, just waiting to get across the tracks and on to Railroad Avenue. How 31.5 many 1000s more cars do you hope to add to the mix? And what will happen when hundreds of houses and businesses are added to the mix on the corner of 13th and Railroad? Most of the City's decisions regarding this issue lack common sense, which makes the whole situation very suspect to those of us in the Canyon. We implore you to re -think this whole project, and if it MUST be done, take a 31.6 long, hard look at using Market Street instead of creating bigger issues with those of us who pay taxes for your paycheck. Finally, our understanding is that there is a legal agreement with the residents of Placerita Canyon to keep the neighborhood rural, as it has been for decades. Perhaps that needs to be looked into as well. Again, please re -consider this outrageous project and the impact that it will have on those who have lived here for many years.

This extension project could ruin the quality of life we in Placerita Canyon appreciate and pay for. I heard many people say that is the reason they purchased their homes in Placerita Canyon (a special standards district established years ago when the city did not want to pay for the road). I also heard homeowners living off Dockweiler opposed to this project because of the increase in traffic that will impact their communities. With the build -out of Santa Clarita I've watched it change tremendously over 25 years. I don't want the traffic and major access to our community that we've fought hard to protect. Placerita Canyon is a special place in Santa Clarita and should stay that way. We have The Masters University, Melody Ranch Studios and churches, along with homeowners here having horses, ranches, etc. I know the Disney Studios will be here soon across the 14 freeway. The rebirth of downtown Newhall is great and I love seeing the community coming together. The City of Santa Clarita seriously needs to reconsider this extension project to protect the Placerita Canyon residents that have lived here for decades, preserve some of our history and what brought people to Santa Clarita in the first place. Tammy Skinner Placerita Canyon Resident 33.1 COMMENT LETTER No. 34 Proposed Alternative to the Dockweiler Extension As briefly discussed at the Master's College meeting, I do believe that the Dockweiler connection is fatally flawed and that another "out of the box" solution should be both considered and explored. 34.1 Fundamental Problems with Dockweiler First, let me state that if Dockweiler did not exist, in other words if there were just an undeveloped hill there, then I do not think anyone would consider this route. It is not only extremely expensive but it is also very disruptive to existing neighborhoods. More fundamentally, this route does not provide the traffic relief or begin to solve the traffic issues that are being considered. Leaving aside human or quality of life improvement goals, the end game of the Dockweiler extension would be to alleviate traffic and to smooth anticipated future circulation in the Valley. 34.2 As I will outline later, this extension not only will not ease the anticipated traffic but, if built as planned, it will actually increase traffic "friction" with added stops, delays, blockages and inconvenient routings. There are non -engineering issues created as well. The purpose here is not to expand upon these, but they are important and worthy of mention: 34.3 • Very high cost of construction due to steep grades and mountain terrain. • Irreversible negative impact upon wildlife (foxes, wild cats, hawks, rabbits, coyotes, deer, native snakes and such). 34.4 • Highly negative impact upon ridgeline view to the community, this will destroy 34.5 the hillside ridges and contours that provide invaluable aesthetic value. • Loss of valuable open space and trails -currently there are several regularly used 34.6 trails through the hills. • Significant quality of life loss in both the Placerita Canyon and in the hilltop Vistas community. ] 34.7 • And, as the Placerita Canyon residents have voiced, there is a significant risk of 34.8 impeded emergency evacuation due to the layout of the proposed extension A more practical approach would mitigate all of the above WHILE providing a more 34.9 effective traffic flow solution as well. Before I touch upon the reasons that the proposed extension will not achieve its 34.10 purpose, let's state the purpose to ensure we are on the same page. There are two potential reasons for the extension: • One, that there is some other reason it is being done than for traffic flow mitigation, such as for expanded development in the hills or simply to finish up a dated plan from 20 years past. 34.10 • Or, to improve traffic flow and allow for the increased development along the Railroad corridor. This is not just for current traffic but for future anticipated traffic as well. This is the purpose that makes the most sense and the purpose that has been stated, so we will proceed on this path. The basic problem is that the extension to Dockweiler does not solve this and is a poor solution to the problem. It will create a number of significant "stop" points throughout the area and will lead to further slows and congestions. These are the problematic stops: • Dockweiler via the Placerita entrance to Sierra Highway is a very poor route for a bypass. This route does not cleanly connect any of the flow lines of the Valley, it starts at a t-intersection and stops at a t-intersection-in effect taking one from nowhere to nowhere. • At each of these terminus points there will be a significant increase in stopped, jammed traffic. In less than a mile, along Railroad, there will now be 5 significant stops and adding this one as a major traffic outlet will add lengthy stops and delays. Then, adding the projected traffic increase, this corridor will be increasingly difficult to navigate. Kia`I • The same is true at Sierra Hwy. Adding lengthy left turn signals and extending stop times will greatly increase the slows along that vital corridor, without achieving much in the way of smoothed traffic. There will be a secondary effect at the Newhall Ave South left turn as this lane will have to be extended and its time length increased. Yet in no way does this route provide easy entrance or exit flow to any desired points, as both ends don't lead anywhere or flow easily. • An analogy can be found in irrigation systems. Every time a turn is introduced this then creates friction, turbulence, slows and loss of pressure. The same is true in traffic, with the added caveat of introducing higher rates of accidents to the process. • As amply discussed in the meetings, this routing will create heavy disruption and slows to the traffic flow in and out of the Placerita Canyon. Enough said. • The Dockweiler extension itself will be a very poor flow. First is the steep grade and potential curves on the route, this never makes for smooth, flowing traffic. Second is the number of stop signs that will be required along the route, minimally these are: at the entrance and exit to Master's College and a minimum of three stop signs through the community on top of the hill (Valle del Oro intersection, apartment exit at the east end and at the Lantana community). It will be very slow going through there. Added to this is the fact that traffic will be merging at both ends from two lanes to a single lane at the top of the hill. So, adding together the longer waits at traffic lights, the merging lanes, the multiple stop signs (or even an additional stop light) and the grades to the fact that this route is NOT convenient to any destination or flow, makes for a very expensive and ineffective plan. TARGET ONE: Aside from a restricted corridor in downtown Newhall, the biggest issues lie in the number of stopping points along the way. These should be addressed and solved as a PRIMARY concern, this is low hanging fruit. Traffic that flows equates to reduced congestion and improved capacity. Proposed improvements would include: • Reposition the bus stop in front of the Metro station. This is the lowest hanging fruit and could be accomplished by eliminating the parking there (there are lots to the rear and south), keeping a drop off zone for passengers and building a pull out for the buses. The stopped bus creates tremendous jams along that area, especially during rush hour. • Consider eliminating the light at Market Street. Make this a right turn only intersection. Yes, this create some inconvenience, but the benefits outweigh the inconvenience. Residents can go south on Pine to exit to the East. Downtown Newhall visitors can go up to Lyons to turn left. Removing this stop will do much to keep traffic flowing. A pedestrian bridge could be built. • The most effective move, but costly, would be to build an overpass directing all Newhall Ave traffic over the intersection and then down to the roundabout. This would eliminate any stops, other than train crossings, for the Railroad to Newhall traffic and keep that flowing. If the Dockweiler extension was not done, this would result in tremendous savings and these funds could be used for the overpass. • There are likely other ways to smooth traffic through Downtown but that should be a priority. TARGET TWO: This would be to find an effective bypass route to pull traffic through the area and also accommodate the increased traffic connected to the planned development along Railroad (vacant land to the west of Placerita Canyon). The ideal here would be to find a less expensive route, to find a more effective route and to find a route that has a lessened negative impact on points mentioned earlier Kia`I [d0if�� (such as wildlife, scenic views, neighborhood disruption, etc.). In addition, finding a route that could potentially provide traffic flow benefits above and beyond what was sought would be ideal. The goal should not be "to build an extension" but to smoothly move traffic, and projected traffic increases, along the Sierra/Newhall-Santa Clarita Railroad Avenue path. The most effective solution would be to have a direct route between Sierra/Newhall and beyond the Downtown Newhall zone. Ideally this direct route would have a minimum of stops or intersections -an express way or bypass route. With the future planned development along the east side of Railroad as well as the future planned connection of Via Princessa across the valley then this route should ideally facilitate flow through the future development and also connect to the Via Princessa route. The proposed route, given of course in simple terms, would avoid the Dockweiler path completely. It would follow flat land for the most part by building along the edge of the creek bed at the base of the hill which is largely flat land. This would keep the bypass route away from any new railroad crossings and out of most all neighborhoods. There are several vacant lots along Newhall Ave where this route could connect and if built properly this route could flow into and out of Newhall without any stop signs or lights. (This would require one overpass and would only allow for traffic in the most probable and heavily used directions) The route would direct traffic into a properly sized roundabout (large enough to accommodate fire trucks and horse trailers) at the Placerita Canyon intersection. This roundabout would be well to the east of the tracks and the current stoplight, to avoid backups in that tight sector). The route would continue on into the new development and then connect into the Via Princessa future route. There are some engineering issues, such as the need to move significant dirt as the route would pass to the east of the Metro station as well as the need for one -to -three overpasses and potentially a bridge -but all of these are doable and are significantly less expensive than connecting to Dockweiler. The most significant plus is that this route would allow for greatly increased traffic flow and speed through the area, and would provide access to the Masters College and the newly developed area. It would provide safer and increased emergency exit from Placerita, minimize neighborhood disruption and loss of quality of life, it would preserve a valuable piece of open space and scenic ridgelines. Ideally that saved open space could be connected to existing open spaces and further improve the area's appeal and outdoor access. With added trails for hikers and horses, and even an extension of our biking paths, this plus would help gain community support for the project as a whole. 34.12 Please see attached map for a general outline of the proposed alternative. 134.12 In closing, while one has always to deal with the NIMBY factor on any development project, the proposed Dockweiler extension lacks the benefits to justify its construction. It is flawed in many ways, but most importantly in that it does not begin to address the projected traffic problems and will in fact lead to increased traffic congestion. If the traffic flow needs to be resolved then this extension needs to be sidelined while alternative plans and routes that actually solve the problem are explored. This is a proposed alternative that would solve the problem. Of course, I have not done feasibility or engineering studies, but this general scope is worth discussion and review.

COMMENT LETTER No. 35 From: Linda Tarnoff [mailto:haveahunchranch@aol.com] Sent: Monday, October 16, 2017 6:28 PM To: Carla Callahan Subject: LYONS/DOCKWEILER EXTENSION PROJECT Unless you can convince me otherwise, I am opposed to the Dockweiler extension unless to just the proposed Masters University expansion project. In other words, I support the No Project alternative. The additional traffic proposed to be routed through our rural equestrian neighborhood would without a doubt jeopardize our community which is already anticipating impacts from the proposed new residential construction at 13th Street. As the Santa Clarita Valley gets built out, obviously there will be a need for additional roads. The success of Golden Valley Road is a prime example. But shunting traffic to an otherwise quiet community is not the solution. Each proposal referenced in the EIR is controversial and not without issues. Market Street is next to an active train station with high numbers of pedestrian traffic especially at peak travel times. No doubt this option is opposed by adjacent residents. Lyons Avenue would be the best scenario as a straight shot across if traveling east on Lyons but appears to have too many construction challenges i.e. need for elevation of existing road to traverse over train tracks and bridge construction over creek. 13th Street, though easiest for the planners is problematic for Placerita Canyon. In addition, at this time-- with the cleanup of Whittaker Bermite on the horizon for 2018 -- it would make sense to initiate the EIR process for the ultimate extension of Via Princessa through to Golden Valley Road. Regardless of which route the city ultimately chooses, the left turn queues will undoubtedly create lengthy back ups jutting into left lanes of traffic as demonstrated by the frequent half mile or more long left turn lanes on Sierra Highway to Golden Valley Road. Just imagine the scenario at a left turn lane from Railroad to Market Street if the road is extended there, on a curve no less. In fact, the left turn lane at 13th Street cannot accommodate traffic as it is at peak times. Change is inevitable but clearly think this one out from the impact on the local impacted communities whether it be Placerita Canyon, East Newhall or Dockweiler.

In the section on Air Quality, I refer to the Global Warming Solutions Act of 2006 (AB 32). This act mandates statewide greenhouse gas emissions must be reduced to 1990 36.1 levels by 2020. SB 32, passed in 2016 and signed into law (before this draft EIR was released) expands that mandate to reduce greenhouse gas emissions 40 percent below 1990 Ievels by 2030. Both are state laws but this report makes no effort to deal with how the additional congestion can be dealt with to comply with state law. LOS; PCPOA met with City staff on July 25 for a presentation on the Draft EIR. We were assured LOS levels A-F did not correspond to scholastic letter grades. The Evans 36.2 Report (page 13) states "The LOS ranges from `A" (the best) through `F" (system breakdown)," That's very similar to scholastic grades. Ongoing transportation issues: • The report posits Lyons as a three -lane avenue. While some of Lyons is three - lanes, the portion from Orchard Village to Railroad allows street parking. 36.3 Merchants have long fought allowing three lanes since there is inadequate off- street parking. OLPH submitted a Master Plan several years ago outlining their proposed expansion; that plan was withdrawn allowing piecemeal expansion. ■ The transportation section proposes two left turn lanes, one right turn lane and one straight ahead lane at Lyons where it meets Railroad; where is this additional lane 36.4 coming from? What provisions are made at this intersection for the traffic from the substantial under -construction parking structure? Or the Laemmle Theater? • Peak hour numbers do not allow for Metro train traffic. Please adjust the report. :3 36.5 • How does the closer proximity to the Newhall Metro station affect crossing I 36.6 safety/timing at this intersection? • What provisions are made for circulation during construction? Nighttime construction is not an answer with a road be being raised six feet or more. (The City is already in a mess with three major construction projects: Railroad, 36.7 Orchard Village and MCBean.) Simply posting signs "Use alternate routes" is not sufficient, particularly when the City has made no effort to adjust the timing of the affected signals. How will traffic get to Lyons from either direction? • Dockweiler parking: The EIR shows Dockweiler as two lanes in each direction. Much of the road by the condos and apartments has been used for years as supplemental parking. What provisions are being made for these vehicles? Many 36.8 of the units are within 10 feet of the existing roadway; how will the quality of life for these residents (safety, noise, pollution) be maintained? ■ If federal funds are sought for any portion of this construction, does that mean the City will have to allow heavy truck traffic on Dockweiler? What safety provisions 36.9 will be made for locals to protect them from trucks barreling down that grade? • Roundabout not safe or adequate for truck traffic or horse trailers. ] 36.10 Think outside the Sox 1. Take traffic up to Circle J. Nice to keep your promises to them, but Placerita has promises written into the General Plan and our Special Standards District to protect our rural equestrian way of life. No part of this proposal is compatible with a rural equestrian lifestyle. 2. Flyover at 150 Street. 3. Bring Dockweiler to Pine Street. Extend to Market and then down to Pine across Newhall Avenue where it goes to NCY D. That avoids trains tracks altogether. -rice 01-e � r7 � - COMMENT LETTER No. 37 LYONS AVE / DOCKWIELER DRIVE EXTENSION PROJECT EIR PUBLIC OUTREACH MEETING PUBLIC COMMENT FORM This form is provided for your convenience to make written comments regarding the Draft Environmental Impact Report (EIR) prepared for the Lyons Avenue /Dockweiler Drive Extension Project.

Regarding the traffic study in the Draft EIR, Dockweiler is a Secondary Highway connecting with Placerita Canyon. Highways and horses do not mix, so this alignment 37.1 has the potential to negate the rural equestrian lifestyle and/or violate the Special Standards District previously established. 2. Dockweiler to 131h St. creates a bypass artery that avoids Downtown Newhall contrary to the economic development objective of the area (traffic study indicates a 31% decrease 37.2 in Lyons traffic from 2019 to 2035 if Alternative #2 goes forward). 3. Dockweiler experiences a 446% increase with Lyons improvement; 272% increase with Alternative #2, yet Railroad Avenue experiences a modest 5% decrease from No Project to Alternative #2. Given the math in the traffic study, neither alternative satisfies the 37.3 City's objective to reduce volume (as presented as travel time) on Newhall Avenue by nearly half. 4. TMU has a dramatic increase in traffic load with the Lyons crossing, yet with No Project and Alternative #2 that load decreases by 10-13,000 vehicles. Question is where 37.4 did those vehicles go? The traffic counts on Dockweiler and 131h do not make up for the variances in the data. The validity of the Alternative #2 traffic load is questionable given the unexplained variances. 5. Safety is a key consideration at an active rail crossing with on average 38 trains per weekday (8 freight and 30 commuter). Alternative #2 has a 92% increase in traffic between 2019 and 2035, which amplifies the risk of rail -related incidents. 37.5 Name: Robert and Teresa Todd Address: 24760 Oakcreek Avenue Newhall, CA 91321 Email: mccabetodd@gmail.com You may also e-mail comments to Ccallahan@santa-clarita.com on or before October 16, 2017.

Please provide your comments below: The expansion of Arch St to Dockweiler is not in the best interests of the residents of Placerita Canyon. My house sits on Placerita Canyon, close to Arch St. I do not see how bringing unnecessary traffic onto our rural streets will in any way improve our neighborhood. When the residents of Happy Valley complained to the city about excessive traffic on Valley St due to the gate at Calgrove being available to the Hidden Valley residents via a gate card, the city SHUT down a road that was on the master plan as a public road. So to tell us the Arch St-Dockweiler expansion "has" to be done because it is on the master plan is false. The ONLY person who wants this road is oddly a City Council member with property that might be of value to the city. Makes one wonder who the City is "serving" Certainly NOT the vast majority of Placerita canyon residents. We would prefer the third option; DO NOTHING. Perhaps the City should finally expand Via Pricessa. That's been promised for years and would actually improve traffic flow in Santa Clarita Name: Dawn and John Zirbel Address: 22124 Placerita Canyon Rd Newhall CA 661-816-1218 Email: dzirbel@firstam.com You may also e-mail comments to Ccallahan@santa-clarita.com on or before October 16, 2017. 42.1 Lyons Avenue/Dockweiler Road Extension Project Final Environmental Impact Report Appendix B Addendum Traffic Impact Analysis A 111] 2 0111111y'l 0 1007A "AT" ®A\ ►\ r.

one of the fastest growing cities in Los Angeles County. The City's General Plan includes several large developments in the area, and traffic volumes are expected to increase significantly. As such the City of Santa Clarita has identified a project to extend Dockweiler Drive to Lyons Avenue. The proposed Dockweiler Drive Alignment project is located in the City of Santa Clarita, approximately 35 miles northwest of the City of Los Angeles, in the Newhall area of the City. Sierra Highway and the SR-14 (Antelope Valley) Freeway provide a boundary for the study area along the eastern side. Through traffic access on Placerita Canyon Road is restricted with a gate entrance west of Sierra Highway. Placerita Canyon Road currently is the primary connection to The Master's College and residents to the north. Newhall Avenue on the southern boundary of the study area provides a direct connection for cross valley traffic and connects Sierra Highway and Railroad Avenue. The UP/Metrolink Railroad line restricts access to the west with three (3) existing at -grade railroad crossings located at 13th Street, Market Street, and Newhall Avenue. Figure 1-1 illustrates the vicinity map and project location. The extension of Lyons Avenue to Dockweiler Drive across the existing Metrolink line has been identified by the City as one (1) of five (5) key transportation projects. The alignment is part of the City's General Plan and consistent with the goals of the Downtown Newhall Specific Plan, Santa Clarita Valley Consolidated Traffic Model (SCVCTM), and the Compass Blue Print Plan. The purpose of the Dockweiler Drive Alignment Project is to ascertain the feasibility of the General Plan alignment for Dockweiler Drive, which identifies the connection of Dockweiler Drive to Lyons Avenue at Railroad Avenue. The project would extend Lyons Avenue from its existing terminus at Railroad Avenue on the west to future Master College Master Plan Dockweiler extension at north of railroad crossing consistent with the Council -approved Compass Blueprint Concept Plan. This project would include the consideration of a new at -grade rail crossing at Lyons Avenue and Railroad Avenue, which is expected to result in the closure of the 13th Street rail crossing. This Addendum report examines the traffic impacts specifically for the Alternative 3: Market Street and provides a comparison to the alternatives presented in the Dockweiler Drive Alignment Project Traffic Impact Analysis. The report also addresses the impacts of overall projected growth within the area to represent utilization of the proposed Dockweiler Drive Alignment alternative. Consideration will be provided to pedestrian, rail, and vehicular traffic within the study area. The study area is based on the North Newhall Specific Plan Stage II. 1.1 City Circulation Plan The Santa Clarita Valley's circulation system is a comprehensive transportation network of roadways, multi -use trails, bicycle paths, bus transit, and commuter rail. This network provides mobility options to Valley residents and businesses. Figure 1-2 illustrates a portion of the Santa Clarita Valley Circulation Plan bounded by the study area. A major component in the development of the Santa Clarita Valley is the inclusion of alternative travel modes and support facilities. These facilities increase efficiency and capacity of existing systems, by promoting mixed -use development near transit facilities. Bicycle lanes and accessibility to bike paths are a fundamental component to a comprehensive transportation network. Figure 1-3 illustrates a portion of the Santa Clarita Valley's Bicycle Master Plan bounded by the study area. j B(JID JICoLL,ER'S �� GE cy z OI 2 U PLACERITA CANYON RD.

Alternative 3 Alternative 3 extends the Dockweiler Drive alignment to intersect with Market Street and Race Street. The Alternative 3 would extend Dockweiler Drive from its existing terminus, westward to Market Street to provide a T-intersection with Race Street. Alternative 3 is illustrated in Figure 1-4. The Dockweiler Drive Alignment Project Traffic Impact Analysis reviewed the following No Build Condition, the Proposed Project, and the two (2) Alternatives. The Proposed Project and Alternatives consider combinations of constructing a new railroad crossing at Lyons Avenue and removing or improving the at -grade crossing at 13th Street. The alternatives are outlined as follows; Proposed Project The Proposed Project utilizes the City of Santa Clarita's General Plan proposed alignment for Dockweiler Drive, which identifies the connection of Dockweiler Drive to extend to Lyons Avenue. The Proposed Project would extend Lyons Avenue from its existing terminus at Railroad Avenue, eastward to Dockweiler Drive to provide a T-intersection. Included in the Proposed Project is reprofiling the intersection of Lyons Avenue and Railroad Avenue to allow the construction of a new SCRA/UP railroad grade crossing east of Railroad Avenue. The new Lyons Avenue railroad grade crossing will improve traffic movements and safety at the railroad crossing. The new crossing will allow the removal of the existing 13th Street and Railroad grade crossing, which will avoid direct impact to the Placerita Canyon neighborhood. The Proposed Project is illustrated in Figure 1-5. Alternative 1 Alternative 1 utilizes the City of Santa Clarita's General Plan proposed alignment for Dockweiler Drive, which identifies the connection of Dockweiler Drive to extend to Arch Street. The project would extend Lyons Avenue from its existing terminus at Railroad Avenue, eastward to Dockweiler Drive to provide a T-intersection. Included in the Alternative 1 is reprofiling the intersection of Lyons Avenue and Railroad Avenue to allow the construction of a new SCRA/UP railroad grade crossing east of Railroad Avenue and construct improvements to the 13th Street rail crossing. Alternative 1 is illustrated in Figure 1-6. Alternative 2 Alternative 2 utilizes the City of Santa Clarita's General Plan proposed alignment for Dockweiler Drive, which identifies the connection of Dockweiler Drive to extend to Arch Street. The route will continue along Arch Street to 13th Street to link to Railroad Avenue. Alternative 2 proposes improvements to the 13th Street rail crossing.

FIGURE 1-7: ALTERNATIVE 2 ADDENDUM REPORT FOR THE PROPOSED EXPANSION OF DOCKWEILER DRIVE SANTA CLARITA, CALIFORNIA 2 EXISTING CONDITION Existing Street System The following roadways provide access to and within the study area; Dockweiler Drive is designated as an east -west Secondary Highway from Sierra Highway to Railroad Avenue on the City of Santa Clarita Circulation Map Joint Highway Plan. The Existing portion of Dockweiler Drive consists of one lane in each direction with a landscaped median and limited parking throughout the study area. Dockweiler Drive is used as the primary access to single- and multi -family residences. State Route 14 Freeway (SR 14) provides regional access within the study area. The freeway is a four -lane (two in each direction) facility with interchange access at Placerita Canyon Road and Newhall Avenue. Lyons Avenue is designated as an east -west major highway east of Railroad Avenue and Secondary Highway west of Railroad Avenue on the City of Santa Clarita Circulation Map Joint Highway Plan. Three lanes in each direction are provided with traffic signals and left turn channelization at major intersections. Newhall Avenue is designated as a north -south secondary highway from Lyons Avenue to Railroad Avenue with one lane in each direction. From Railroad Avenue to SR-14, Newhall Avenue is designated as a major highway with three northbound lanes and three southbound lanes south of Railroad Avenue. Newhall Avenue roadway designation is identified on the City of Santa Clarita Circulation Map Joint Highway Plan. Railroad Avenue (formerly San Fernando Road) is a north -south major highway from Magic Mountain Parkway to Lyons Avenue and a secondary highway from Lyons Avenue to Newhall Avenue. This roadway provides two lanes in each direction and limited parking throughout the study area. Railroad Avenue roadway designation is identified on the City of Santa Clarita Circulation Map Joint Highway Plan. Sierra Highway is an old alignment of SR-14 from Los Angeles to Mojave. It is designated as a north -south major highway on the City of Santa Clarita Map Joint Highway Plan. It is a four lane (two in each direction) with traffic signals and left turn channelization at major intersections. Placerita Canyon Road is an east -west local roadway. This roadway provides a gate at the western entrance. The gate provides restrictive access to residents of the Placenta Canyon neighborhood. 13t" Street is an east -west unimproved local roadway. This roadway provides access to The Master's College and the Placenta Canyon neighborhood via its intersection with Railroad Avenue. One lane is provided in each direction. Market Street is an east -west local roadway. This roadway provides a rail crossing and access to a residential community. The roadway is primarily two lanes (one in each direction) with a turn lane at key intersections. 10 As presented, in Figure 2-1, the project begins at the terminus of Dockweiler Drive 500 feet west of Valle Del Oro. Based on potential traffic impacts to the area roadways, twenty (20) intersections have been identified for analysis; 1. Sierra Highway and SR-14 SB Ramps 2. Sierra Highway and Placerita Canyon Rd 3. SR-14 NB Ramps and Placerita Canyon Rd 4. Sierra Highway and Dockweiler Dr 5. SR-14 SB Ramps and Newhall Ave 6. Sierra Highway and Newhall Ave 7. Valle Del Oro and Newhall Ave 8.

Market St (West) and Newhall Ave Existing Traffic Volumes As referenced from the City of Santa Clarita Circulation Element, Average Daily Traffic (ADT) is a measurement of the average number of vehicles that travel a segment of roadway during a 24- hour period. The ADT is a useful benchmark for determining roadway capacities. Figure 2-1 illustrates the existing street system ADT and the study intersection locations. The existing 2013 ADT map for the Santa Clarita Valley is referenced from the city website. Figure 2-2 illustrates the existing peak hour traffic volumes in the study area. As referenced from the City of Santa Clarita Circulation Element, Peak hour information, which is the highest volume of traffic to pass over a road in a one -hour period, allows for a more detailed method of evaluating traffic conditions along roadways and intersections, and is used whenever operational analysis is required. The traffic volume data used in the intersection capacity analysis were based on traffic counts conducted by Newport Traffic Studies, an independent traffic data collection company. Turn movement counts were collected during the AM (7-9 AM) and PM (4-6 PM) peak periods at the above -mentioned existing intersections identified for detailed analysis. The counts taken at intersections 1-16 were conducted in December 2012. The counts taken at intersections 21-23 were conducted in December 2017.

SANTA CLARITA, CALIFORNIA Capacity Analysis Methodologies Based on the existing intersection geometrics and traffic volumes during the AM and PM Peak Hour, the intersection capacity analyses were conducted for the signalized and un-signalized intersections using the Synchro Software. Synchro is released by Trafficware Ltd, version 8. Synchro implements the methods of the 2010 Highway Capacity Manual, chapter 15, 16 and 17; Urban Streets and Signalized intersections. The analysis determines a level -of -service (LOS) which quantitatively describes the operating characteristics of signalized intersections and the maximum delay. The LOS ranges from "A" (the best) through "F" (system breakdown). The level - of -service is based on the average delay of vehicles at the intersections. Table 2-1 provides the LOS thresholds for signalized intersections per the HCM 2010 methodology. Table 2-1: HCM 2010 - LOS Criteria for Signalized Intersections LOS Control Delay per Vehicle (s/veh) A <10 B > 10 and <20 C > 20 and <35 D > 35 and <_ 55 E > 55 and <_ 80 F > 80 Source: HCM 2010 For un-signalized intersections the HCM measures the LOS based on the computed or measured control delay for Two Way Stop Controlled intersections (TWSC) and control delay for All Way Stop Controlled (AWSC) intersections. For a TWSC the LOS is computed for each movement and the most critical LOS is the one that describes the effectiveness of that intersection, which is typically the stop controlled left turn movement from the minor street. For an AWSC intersection the LOS defines the whole intersection. Table 2-2 provides the LOS thresholds for TWSC and AWSC intersections per the HCM 2010 methodology. Table 2-2: HCM 2010 - LOS Criteria for TWSC, AWSC, and Roundabout Intersections LOS Control Delay per Vehicle s/veh A <_ 10 B > 10 and <15 C > 15 and <25 D > 25 and <_ 35 E > 35 and <_ 50 F > 50 Source: HCM 2010 The intersection capacity analyses were conducted for the roundabout intersections using the Sidra Intersection Software. Sidra is released by Akcelik & Associated Pty Ltd, version 6.0. Sidra Intersection 6.0 implements the methods of the 2010 Highway Capacity Manual, Chapter 21. For the roundabout intersections the HCM measures the LOS based on the control delay and the LOS defines the whole intersection. The level -of -service is based on the average delay of vehicles at the intersections. Table 2-2 provides the LOS thresholds for roundabout intersections per the HCM 2010 methodology. The City of Santa Clarita preferred maximum acceptable level of service on arterial roads is LOS E. The City of Santa Clarita desired maximum acceptable level of service on residential neighborhood roads is LOS C or better. 14 2.1 Existing Traffic Analysis To determine the impacts of the project to the study intersections, existing traffic intersection capacity analysis was conducted.

The proposed Dockweiler Drive Alignment project is enclosed by a residential community near The Master's College. Sierra Highway provides a boundary for the study area along the eastern side. Through traffic access on Placerita Canyon Road is restricted with a gate entrance west of Sierra Highway. Placerita Canyon Road currently is the primary connection to The Master's College and residents to the north. Newhall Avenue on the southern boundary of the study area provides a direct connection for cross valley traffic and connects Sierra Highway and Railroad Avenue. The UP/Metrolink Railroad line restricts access to the west with three (3) existing at -grade railroad crossings located at 13th Street, Market Street, and Newhall Avenue. The study area is determined based on the North Newhall Specific Plan Stage II. The Dockweiler Drive Alignment project is intended to serve as a major east -west corridor link in the area to facilitate access to existing and planned development. The project is proposed to aid the future traffic consistent with the Santa Clarita Valley Consolidated Traffic Model (SCVCTM). Construction of this link is anticipated to reduce "cross valley" trip lengths and travel times, provide an alternate travel route, support a multi -modal transportation network by reducing bus travel times in the City and by providing the opportunity for increased bike and pedestrian traffic. Project Year 2019 Traffic Analysis A project year of 2019 has been identified as the opening year for the Dockweiler Drive Alignment project. As presented, Alternative 3 extends the Dockweiler Drive alignment to intersect with Market Street and Race Street. The Alternative 3 would extend Dockweiler Drive from its existing terminus, westward to Market Street to provide a T-intersection with Race Street. A major factor in distribution of traffic is the anticipated growth within the study area due to development. The Year 2019 traffic volumes were provided by the City of Santa Clarita using the Santa Clarita Valley Consolidated Traffic Model (SCVCTM) for the Interim Year. The Alternative 3 was modeled to account for the differing distribution of traffic dependent on the other alternatives. It is to be noted that Other Area Projects anticipated to be constructed by Year 2019, have been incorporated into the SCVCTM, and account for expected growth. The Year 2019 intersection turn movements were primarily taken directly from the Interim Year SCVCTM specific to each alternative. A few intersection turn movements were determined using existing counts and the link volumes from the Year SCVCTM specific to the alternative. These values were then used in a 7uture Directional Link Volume (NCHRP 255)' calculator to determine Year 2019 Turn Movement Volumes. The intersections included were Valle Del Oro and Dockweiler Drive, Railroad Avenue and Market Street, Main Street and Lyons Avenue, Main Street and Newhall Avenue, Arch Street and 12th Street/Placerita Canyon Road, Lyons Avenue and Dockweiler Drive, Aden Avenue and Dockweiler Drive, Aden Avenue and Placeritos Boulevard, Aden Avenue and Placerita Canyon Road. 3.1 Alternative 3 Condition The SCVCTM Interim Year model plots provided traffic volumes for the Alternative 3 Project Year 2019 Condition.

This roadway is proposed to aid the future traffic growth consistent with the Santa Clarita Valley Consolidated Traffic Model (SCVCTM). Future Year 2035 Traffic Analysis Future Year 2035 traffic volumes were provided by the City of Santa Clarita using the Santa Clarita Valley Consolidated Traffic Model (SCVCTM) for the Buildout Year. Each alternative was modeled to account for the differing distribution of traffic dependent on the alternative. It is to be noted that Other Area Projects anticipated to be constructed by Year 2035, have been incorporated into the SCVCTM, and account for expected growth. The buildout includes construction of future roadways Golden Valley Road between Newhall Ranch Road to Valley Center Drive, Magic Mountain Parkway from Railroad Avenue to Via Princessa, and Via Princessa between Claibourne Lane and Sheldon Avenue. This also includes the proposed conceptual development of the North Newhall Specific Plan area an 809 dwelling unit plus an approximate 11 acre commercial land use. The Future Year 2035 intersection turn movements were primarily taken directly from the Buildout Year SCVCTM specific to the alternative. A few intersection turn movements were determined using existing counts and the link volumes from the Year SCVCTM specific to the alternative. These values were then used in a 'Future Directional Link Volume (NCHRP 255)' calculator to determine Future Year 2035 Turn Movement Volumes. The intersections included were Valle Del Oro and Dockweiler Drive, Railroad Avenue and Market Street, Main Street and Lyons Avenue, Main Street and Newhall Avenue, Arch Street and 12th Street/Placerita Canyon Road, Lyons Avenue and Dockweiler Drive, Aden Avenue and Dockweiler Drive, Aden Avenue and Placeritos Boulevard, Aden Avenue and Placerita Canyon Road. 4.1 Alternative 3 Condition The Santa Clarita Valley Consolidated Traffic Model (SCVCTM) for Build -Out Year provided traffic volumes for the Future Year 2035 Condition. The model plots provided a No -Build Condition outlining the distribution of future traffic without the project. The analysis of No -Build Condition utilizes the traffic volume projections for the City of Santa Clarita's traffic model together with the existing traffic flow data. The traffic projections are based on the General Plan Buildout. The buildout includes construction of future roadways Dockweiler Drive between Railroad Avenue and Val Del Oro, Golden Valley Road between Newhall Ranch Road to Valley Center Drive, Magic Mountain Parkway from Railroad Avenue to Via Princessa, and Via Princessa between Claibourne Lane and Sheldon Avenue. This also includes the proposed conceptual development of the North Newhall Specific Plan area an 809 dwelling unit plus an approximate 11 acre commercial land use.

Furthermore the City and County must coordinate with regional transportation plan. Consideration to said code the City of Santa Clarita utilized regional plans affecting the Santa Clarita Valley. Those regional plans included California Department of Transportation (Caltrans); the Regional Mobility Plan prepared by the Southern California Association of Governments (SCAG); the Los Angeles Metropolitan Transportation Authority's (MTA or Metro) Congestion Management Program and bicycle way strategic plan; Santa Clarita Transit's Transportation Development Plan (TDP); and Los Angeles County's Airport Land Use Plan. The Santa Clarita Valley's circulation system provides vital connections linking neighborhoods, services, and employment centers throughout the community and the region. A comprehensive transportation network of roadways, multi -use trails and bicycle paths, bus transit, and commuter rail provides mobility options to Valley residents and businesses. Planning for the ultimate location and capacity of circulation improvements will also enhance economic strength and quality of life in the Valley. Consideration to the Santa Clarita Valley's continued development of efficient, cost-effective and comprehensive transportation systems that are consistent with regional plans, and local needs. The Circulation Plan identifies and promotes a variety of techniques for improving mobility that go beyond planning for construction of new streets and highways. A major component in the development of the Santa Clarita Valley is the inclusion of alternative travel modes and support facilities. These facilities increase efficiency and capacity of existing systems, by promoting mixed -use development near transit facilities. Bicycle lanes and accessibility to bicycle paths are fundamental to a comprehensive transportation network. The Santa Clarita Valley's Bicycle and Pedestrian Facilities is provided in Figure 6-1. As illustrated in Figure 6-1, Potential Bike Lane connectors are proposed from Dockweiler Drive to connect to the Proposed Class I Bike Path along Railroad Avenue and the Proposed Class I Bike Path along Railroad Avenue. 29 PROPOSED CLASS 1 BIKEPATH \ PCAOER�TA NYDN RD • 00 \ �FR DR• POTENTIAL \ BIKE LANE Y CONNECTORS w J Q U cn 0 0 z PROPOSED CLASS 2 BIKELANE PROPOSED CLASS 1 BIKEPATH X FIGURE 6-1: SANTA CLARITA VALLEY'S EXISTING' -.

EXECUTIVE SUMMARY A. INTRODUCTION (a) Purpose of the EIR The purpose of this Draft Environmental Impact Report (Draft EIR) is to inform decision makers and the general public of the potential environmental impacts resulting from the proposed Dockweiler Drive Alignment Project ("Proposed Project"). The Proposed Project will require approval of certain discretionary actions by the City of Santa Clarita, and therefore, is subject to environmental review requirements under the California Environmental Quality Act (CEQA). For purposes of complying with CEQA, the City of Santa Clarita, located at 23920 Valencia Boulevard, CA 91355 is identified as the Lead Agency for the Proposed Project. As described in Section 15121(a) and 15362 of the CEQA Guidelines, an environmental impact report is an informational document which will inform public agency decision -makers and the public of the significant environmental effects of a project, identify possible ways to mitigate any significant environmental effects, and identify and evaluate a reasonable range of alternatives to the project that have the potential to mitigate or avoid the project's potential significant environmental effects while feasibly accomplishing most of the project's basic purposes. Therefore, the intent of this Draft EIR is to focus the discussion on the Proposed Project's potential physical effects on the environment, which may be significant under the methodology and thresholds of significance identified within each Section of this Draft EIR. Where applicable, the Draft EIR recommends feasible mitigation measures that could potentially reduce or avoid significant environmental impacts. This Draft EIR was prepared in accordance with Section 15151 of the CEQA Guidelines, which defines the standards for adequacy of an environmental impact report as follows: An EIR should be prepared with a sufficient degree of analysis to provide decision makers with information which enables them to make a decision which intelligently takes account of environmental consequences. An evaluation of the environmental effects of a Project need not be exhaustive, but the sufficiency of an EIR is to be reviewed in the light of what is reasonably feasible. Disagreement among experts does not make an EIR inadequate, but the EIR should summarize the main points of disagreement among the experts. The courts have looked not for perfection but for adequacy, completeness, and a good faith effort at full disclosure. Lyons Avenue/Dockweiler Drive Extension Project 1. Executive Summary SCH No. 2013082016 Page 1-1 City of Santa Clarita August 2017 (b) Overview of the Proposed Project Project Location The Project Site is located in the City of Santa Clarita, California located about 35 miles north of Downtown Los Angeles. The Project Site is located at the intersection of Lyons Avenue and Railroad Avenue and extends eastward towards the General Plan alignment for Dockweiler Drive towards The Master's University and northwest towards the intersection of 12th Street and Arch Street. The Project Site also includes the closure of an at -grade crossing at the intersection of Railroad Avenue and 13th Street. The limits for the Lyons Avenue/Dockweiler Drive extension ("Project Site") are from Railroad Avenue on the west to the future Master's University Master Plan Dockweiler extension to the east. Overview of the Environmental Setting The Project Site is currently zoned for MXN (Mixed Use Neighborhood). The portion of the Project Site that crosses the UP/Metrolink Railroad line is zoned for PI (Public Institutional). The General Plan land use designation of the Project Site is Mixed Use Neighborhood (MXN). The General Plan states that areas with a MXN designation should be developed to create neighborhoods that combine residential uses with complementary commercial services, including retail and office uses. MXN zoned areas should be located in close proximity to public transit and provide roadway and trail linkages to adjacent development. The PI zoning designation identifies lands that are used for various types of public or/and community serving facilities owned and operated by public agencies, special districts, nonprofit organizations and other entities. Allowable uses include civic and governmental offices, public works yards, public or private schools, libraries, day care centers, airports, hospitals and supporting medical facilities, museums, fire stations, police stations, landfills, and prisons. The Project Site is also located in the Placerita Canyon Special Standards District (PCSSD) and is part of the North Newhall Area (NNA), which includes a Mixed Use Overlay Zone. Overview of the Proposed Project The Proposed Dockweiler Drive Alignment Project is a multi -phased capital improvement project being coordinated by the City of Santa Clarita and The Master's University to improve circulation and access to the Placerita Canyon and Newhall Communities. The proposed connection and extension of Lyons Avenue to Dockweiler Drive is identified in the Circulation Element of the City's General Plan as one of the primary east -west arterials through the City of Santa Clarita that would provide a through connection from Sierra Highway to Railroad Avenue. The Proposed Project would extend Lyons Avenue from its existing terminus at Railroad Avenue, eastward to Dockweiler Drive to provide a T-intersection, and would extend northwest to connect with the intersection of Arch Street and 12th Street and southeast towards the General Plan alignment for Dockweiler Drive at The Master's University. The Proposed Project also includes the closure of an at -grade railroad crossing at the intersection of 13th Street and Railroad Avenue and the addition of a new at -grade railroad crossing at the intersection of Railroad Avenue and the proposed Lyons Avenue intersection. The Lyons Avenue/Dockweiler Drive extension would extend to the approved alignment of Lyons Avenue/Dockweiler Drive Extension Project 1. Executive Summary SCH No. 2013082016 Page 1-2 City of Santa Clarita August 2017 Dockweiler Drive at The Master's University campus. In coordination with the proposed Railroad Bike Path project, the new Dockweiler Drive extension will result in creating a vital Complete Street link between the communities to the east of the railroad/ Newhall Creek (including The Master's University) and Old Town Newhall and Metrolink station. A detailed description of the Proposed Project including specific street improvements is presented in Section 2.0 Proposed Project. B. ENVIRONMENTAL REVIEW PROCESS (a) Notice of Preparation/Scoping Meeting In compliance with Section 15082 of the CEQA Guidelines, a Notice of Preparation (NOP) was prepared by the City of Santa Clarita and distributed to the State Clearinghouse, Office of Planning and Research, responsible agencies, and other interested parties on August 5, 2013. The NOP and Notice of a Public Scoping Meeting was circulated for public review and comments for a 30-day period beginning on August 5, 2013 and ending on September 3, 2013. Appendix A to this Draft EIR contains a copy of the NOP and written responses to the NOP, respectively. The public scoping meeting was held on August 21, 2013, to obtain the public's initial views about environmental issues that should be evaluated in the Draft EIR in connection with the Proposed Project. City staff and representative technical consultants involved in the preparation of the EIR attended the scoping meeting. Comment letters were received by the following governmental agencies and organizations: (1) State of California, Governor's Office of Planning and Research (OPR), (2) California Native American Heritage Commission, (3) California Department of Fish and Wildlife; (4) California Public Utilities Commission (5) County of Los Angeles Chief Executive Office; (6) Los Angeles County Metropolitan Transportation Authority (Metro); (7) Southern California Gas Company, (8) the Southern California Regional Rail Authority (Metrolink). In addition to the responding governmental agencies, approximately 47 individuals provided written comments on the NOP. Appendix A to this Draft EIR contains the written comments provided to the City during the public scoping meeting, and the names of those in attendance at the scoping meeting who signed in requesting to be kept informed of the Project. (b) Environmental Issues Analyzed in the Draft EIR Based on a review of environmental issues by the City, the Initial Study, the responses to the NOP, and the input received at the public scoping meeting, this Draft EIR analyzes the following environmental issues: • Aesthetics (Views, Light and Glare) • Air Quality • Biological Resources • Cultural Resources • Geology and Soils • Land Use and Planning • Hydrology and Water Quality • Noise • Traffic and Transportation Lyons Avenue/Dockweiler Drive Extension Project 1. Executive Summary SCH No. 2013082016 Page 1-3 City of Santa Clarita August 2017 A summary of the Proposed Project's environmental impacts, mitigation measures, and level of impact after mitigation is presented in Table 1-1, Summary of Environmental Impacts and Mitigation Measures, beginning on page 1-7. (c) Alternatives to the Proposed Project In compliance with Public Resources Code Section 21100 (4), and Sections 15121, 15126, and 15126.6 of the State CEQA Guidelines, the EIR evaluated a reasonable range of Project Alternatives. As discussed in greater detail in Section 6.0, Alternatives to the Project, the range of alternatives selected was based on the ability to feasibly attain most of the basic objectives of the proposed Project and the alternatives ability to avoid or substantially lessen any of the significant effects of the proposed Project. The Alternative Analysis includes the evaluation of a No Project Alternative (as mandated by CEQA), and two alternative alignments: Alignment Alternative 1 and Alignment Alternative 2. Alignment Alternative 1 would include the proposed roadway alignment and associated infrastructure of a new at -grade crossing at Lyons Avenue and Railroad Avenue and a secondary east -west arterial roadway connecting Lyons Avenue to the approved alignment of Dockweiler Drive at the Master's University Campus that would connect Dockweiler Drive to a new five -leg intersection at the Arch Street/12a' Street/Placerita Canyon intersection. This alignment is similar to the Proposed Project except that the 13a' Street at -grade crossing would remain operational under this alternative as opposed to being closed. Alignment Alternative 2 would involve the development of the proposed roadway alignment and associated infrastructure for Dockweiler Drive, as proposed, connecting Dockweiler Drive from the approved alignment at the Master's University Campus to the Arch Street/12a' Street/Placerita Canyon intersection, but without the construction of a new at -grade crossing and connection from Lyons Avenue at Railroad Avenue. As evaluated in Section 6.5, Environmentally Superior Alternative, Alternative 2 was identified as the environmentally superior alternative as it would feasibly attain most of the basic objectives of the proposed Project to provide an additional connection from the Old Town Newhall community to Dockweiler Drive as contemplated under the Circulation Element of the General Plan, and although it would not reduce or eliminate the proposed Project's significant and unavoidable short-term localized construction air quality and construction noise impacts, it would reduce impacts associated with air quality, biological resources, cultural resources, geology/soils, hydrology, construction noise, aesthetics and traffic. Specifically, Alternative 2 would retain the existing aesthetic conditions and views at the Lyons Avenue and Railroad Avenue intersection, would avoid ground disturbance within Newhall Creek, and would reduce the total combined number of railroad crossing events at 13a' Street, Market Street, Newhall Avenue and Lyons Avenue. The total average daily traffic railroad crossings is anticipated to be lowest under the Alternative 2 alignment for both the 2019 and 2035 buildout years. In 2019, Alternative 2 would result in 820 fewer crossings than the proposed Project and 3,160 fewer crossings than Alternative 1. For Year 2035, the total average daily traffic railroad crossings under Alternative 2 would result in 6,230 fewer crossings than the proposed Project and 8,740 fewer crossings as compared to Lyons Avenue/Dockweiler Drive Extension Project 1. Executive Summary SCH No. 2013082016 Page 1-4 City of Santa Clarita August 2017 Alternative 1. As such the Alternative 2 alignment would minimize railroad crossing events and would therefore be environmentally superior to the proposed Project. (d) Environmental Review Process The Draft EIR will be circulated for review and comment by the public and other interested parties, agencies, and organizations for a period of 60 days. After completion of the 60 day review period, a Final EIR will be prepared that responds to comments on the Draft EIR submitted during the review period and modifies the Draft EIR as required. Public hearings on the proposed Project will be held after completion of the Final EIR. The City will make the Final EIR available to agencies and the public prior to considering certification of the Final EIR. Notice of the time and location will be published prior to the public hearing date.

Views of the intersection of Lyons Avenue and Railroad Avenue and the hillside on the southeast portion of the Project Site will be altered by grading for the proposed roadway alignment. Views of the Project Site at the intersection of Railroad Avenue and 13'h Street will also be altered as a result of the closure of the at -grade railroad crossing. The extension of the proposed roadway is consistent with the City of Santa Clarita's General Plan and with the approved Master's University Master Plan. The roadway extension would be developed in accordance with the Lyons Avenue/Dockweiler Drive Extension Project 1.

Replacement oak trees would be planted in the number necessary to comply with the requirements stipulated in the Oak Tree Permit issued by the City. With approval of the required oak tree permits, and implementation of Mitigation Measure 4.3-7 in Section 43, Biological Resources, aesthetic impacts associated with the loss or pruning of any oak tree would be reduced to less than significant levels. No mitigation measures are required. .41teration ofA Significant Ridgeline Less Than Significant Impact. Construction of the proposed roadway alignment will permanently alter a significant ridgeline as designated in the City of Santa Clarita General Plan. The eastern segment of the Dockweiler alignment was previously approved under a separate project entitlement for The Master's University in 2009. which included a Ridgeline Alteration Permit for the eastern segment of this ridgeline, As part of the approved errlillernents for The Master's College Plant in 2008. the extension of Dockweiler Drive east of the Project Site was found to result in the permanent and irreversible grading and re -contouring of the ridgeline. The grading limits of the proposed Project would retain the gradual elevation profile of the base of the ridgeline. Views of the altered portion of the ridgeline would be visible from limited points along the public rights -of -way along Market Street and Race Street to the south of the Project Site. As a project design feature the grading plan incorporates iandform grading practices to bland the manufactured slopes and required drainage benches into the natural topography to the maximum extent feasible. Plant materials will be utilized to protect slopes from slippage and soil erosion and minimize the visual effects of Dockweiler Drive Alignment Project I.

Sources of emissions during construction include: stationary and mobile uses of construction equipment, construction vehicles (heavy-duty construction vehicles and worker vehicles). and energy use. Additionally. earthwork and construction activities would generate fugitive dust emissions. These construction -related emissions and their associated air quality impacts would be short-term in nature and limited only to the period when construction activity is actively taking place. The Proposed Project's construction emissions would be below SCAQMD's significance thresholds for all criteria pollutants. Therefore, the Proposed Project's regional construction air quality emissions would be No mitigation measures are required. Less Than Significant less than significant. Impact. AQMP Consistency The Proposed Project would not exceed the AQMD's significance thresholds for regional construction emissions and thus would not increase the frequency or severity of existing air quality violations or cause or contribute to new air quality violations within the Basin. The Project is consistent with the AQMP and would not interfere with attainment of air quality levels identified in the AQMP. The Project would help reduce congestion and vehicles per miles travelled by providing sidewalks and bicycle lanes and by providing direct access from the residential area and Master's University area to the Jan Heidt Newhall Metrolink Station and Old Town Newhall.

The Proposed Project would be required to prepare and implement a SWPPP prior to earthworm activities that will use best management practices and erosion control measures to prevent pollution in stormwater discharge. All Project construction activities would comply with the City's grading permit regulations. which require the implementation of grading and dust control measures.. including a wet weather erosion control plan if construction occurs during rainy season, as well as inspections to ensure that sedimentation and erosion is minimised. Therefore, through compliance with NPDES requirements and City grading regulations, the Project's construction impacts related to water quality would not violate any water quality standards or waste discharge requirements or otherwise substantially degrade water quality.

Executive Summary State Clearinghouse No. 2013082016 Page I-37 2.0 PROJECT DESCRIPTION 2.1 PROJECT LOCATION The Project Site is located in the City of Santa Clarita, California, about 35 miles north of Downtown Los Angeles. The Project Site is more specifically located in the Newhall community of the City of Santa Clarita at the intersection of Lyons Avenue and Railroad Avenue and extends eastward towards the General Plan alignment for Dockweiler Drive towards The Master's University and northwest towards the intersection of 12'b Street and Arch Street. The limits for the Lyons Avenue/Dockweiler Drive extension ("Project Site") are from Railroad Avenue on the west to the future Master's University Master Plan Dockweiler extension to the east (see Figure 2-1, Project Location Map). Regional Access Regional access to the Project Site is provided from the State Route 14 Freeway to the east and the Golden State/Santa Ana Freeway (I-5) Freeway to the west. SR-14 is located 1.9 miles southeast of the Project Site via Railroad Avenue and Newhall Avenue. The I-5 Freeway is located 2.1 miles west of the Project Site via Lyons Avenue. The SR-14 and I-5 Freeways run in a north -south direction and provides connections to the Ronald Reagan (CA-118) freeway, the San Diego (I-405) freeway, and the Foothill (I- 210) freeway to south of the Project Site. Local Access The following roadways provide local access to the Project Site: Dockweiler Drive is designated as an east -west secondary highway and consists of one and two lanes of travel in each direction. Lyons Avenue is an east -west major roadway that provides three lanes of travel in each direction and provides access from the project area to I-5. Newhall Avenue is a north -south secondary highway from Lyons Avenue to Railroad Avenue with one lane of travel in each direction. From Railroad Avenue to SR-14, Newhall Avenue is designated as a major highway with three northbound lanes and three southbound lanes south of Railroad Avenue. Placerita Canyon Road, west of SR-14 is an east -west local street with one lane of travel provided in each direction. Through traffic access on Placerita Canyon Road is restricted with a gate entrance west of Sierra Highway. Placerita Canyon Road is currently the primary connection to The Master's University and residential neighborhood to the north. Railroad Avenue is a north -south secondary highway from Lyons Avenue to Newhall Avenue. This roadway provides two lanes of travel in each direction and limited parking throughout the project area. 13'b Street is an east -west unimproved local roadway with one lane of travel in each direction and provides a connection to Placerita Canyon Road.

The nearest Metrolink train station to the Project Site is the Jan Heidt Newhall station located at Railroad Avenue and Market Street, approximately 0.25 mile south of Lyons Avenue. The Newhall station provides passenger service southbound to Los Angeles and northbound to Lancaster. The Newhall station also provides connections to the City's local bus lines 1, 2, 4, 5, 6, 14 and 757. Additionally, the City's Bicycle Master Plan is proposing a Class I Bike Path and Class II Bike Lane in the immediate vicinity of the Project Site, which will improve bicycle and pedestrian circulation. 2.2 ENVIRONMENTAL SETTING The Project Site consists of improved segments of Railroad Avenue and Lyons Avenue roadways and undeveloped land to the east extending towards The Master's University and Arch Street. The west end of the Project Site encompasses portions of Newhall Creek and traverses a storage yard, utilized by Los Angeles County Department of Public Works, and private properties. The portion of the Project Site that includes the intersection of Railroad Avenue and 13a' Street is developed with existing road surface and an at -grade crossing. The UP/Metrolink Railroad line crosses the Project Site east of the intersection of Railroad Avenue and Lyons Avenue and at the intersection of Railroad Avenue and 13a' Street. The proposed road alignments are located on the alluvial flood plain and hillside areas adjacent to Newhall Creek. The Project Site is covered with light to moderate growth of natural grasses and chaparral. Elevations at the Project Site range from approximately 1255 feet to 1370 feet above mean sea level. The current conditions of the Project Site at Railroad Avenue and Lyons Avenue are depicted in Figures 2-2 and 2-3 (Views 1 through 8). The current conditions of the Project Site at Railroad Avenue and 13a' Street are depicted in Figures 2-4 (Views 9 through 12). Placerita Canyon Community The Project Site is located immediately southwest of the Placerita Canyon community. The City of Santa Clarita's General Plan (General Plan) describes the Placerita Canyon community as a rural, equestrian - oriented residential area, which is located northeast of Old Town Newhall. East of SR-14, Placerita Canyon is predominantly undeveloped with much of the land contained in the Angeles National Forest. Placerita Canyon is home to The Master's University, a private four-year liberal arts institution, and the Placerita Canyon Nature Center. The General Plan states that planning issues in Placerita Canyon include; accommodating expansion plans for The Master's University; upgrading non -compliant older structures; extending sewer lines to serve existing uses throughout the area to protect groundwater quality; providing flood control and drainage improvements; providing additional vehicular access, possibly through extension of Dockweiler Drive; and opportunities for future development of the 100-acre site located at the westerly entrance of Placerita Canyon. In addition, development in the area must comply with the City's Special Standards District to maintain the rural community character desired by residents.

As described in the Old Town Newhall Specific Plan (Specific Plan), Newhall was the earliest permanent settlement in the Santa Clarita Valley. Access to Old Town Newhall is provided by three commercial arterial corridors, which include, Railroad Avenue, Lyons Avenue and Newhall Avenue. Old Town Newhall is composed of two neighborhoods, which are separated from one another by the railroad and Downtown, a 15-block Downtown area and the three existing commercial arterial corridors. Old Town Newhall is characterized by commercial uses along Main Street and Lyons Avenue and multi -family and single-family residential uses north and south of Lyons Avenue. William S. Hart Park, Newhall Creek and a number of historic buildings add to the character of the community. The General Plan states that planning issues for Newhall include the implementation of the Specific Plan through redevelopment efforts, creating a mixed use, transit -oriented, pedestrian -friendly, live -work -play environment, the future extension of Dockweiler Drive to Lyons Avenue, the future expansion of The Master's University campus, and providing any needed drainage infrastructure improvements. The Master's University and Dockweiler Drive Extension The Master's University is a private four-year liberal arts college located in the Placerita Canyon and Newhall community of Santa Clarita. The Master's University was founded in 1927 in downtown Los Angeles and moved to Placerita Canyon in 1961. The Master's University offers undergraduate degrees in 13 majors from nearly 60 areas of study, and three Master of Arts degrees in biblical counseling, biblical studies, and education. The Master's University campus is approximately 100 acres in size and has a population of over 1,000 students. The Master's University Master Plan (Master Plan) was approved in 2009 and was designed to guide campus growth over the next ten years. The Master Plan ensures development is consistent with the goals, objectives, principles and policies of stakeholders including the City of Santa Clarita and local community. Key features of the Master Plan include the expansion and addition of educational facilities and dormitories and the construction of a new auditorium. In order to accommodate the future expansion of the campus, the Master Plan includes the proposed extension of Dockweiler Drive from its current terminus near Valle Del Oro, through The Master's University property south of the main campus, to the western boundary of The Master's University property. The extension of Dockweiler Drive is a critical east -west link that would provide a through connection from Sierra Highway to Lyons Avenue. The extension would also relocate the main entry to The Master's University from Placerita Canyon Road and redirect traffic from Placerita Canyon Road onto Dockweiler Drive. Lyons Avenue/Dockweiler Drive Extension Project 2. Project Description SCH No. 2013082016 Page 2-7 City of Santa Clarita August 2017 2.3 ZONING AND LAND USE DESIGNATIONS Pursuant to the Santa Clarita Municipal Code (SCMC), the portion of the Project Site located at 13th Street and Railroad Avenue and Lyons Avenue and Railroad Avenue is currently zoned for MXN (Mixed Use Neighborhood). The portion of the Project Site that crosses the UP/Metrolink Railroad line is zoned for PI (Public Institutional). The General Plan land use designation of the Project Site is Mixed Use Neighborhood (MXN). The General Plan states that areas with a MXN designation should be developed to create neighborhoods that combine residential uses with complementary commercial services, including retail and office uses. MXN zoned areas should be located in close proximity to public transit and provide roadway and trail linkages to adjacent development (See Figure 2-5, Zoning and Land Use Map of Project Site and Surrounding Area). The PI zoning designation identifies lands that are used for various types of public or/and community serving facilities owned and operated by public agencies, special districts, nonprofit organizations and other entities. Allowable uses include civic and governmental offices, public works yards, public or private schools, libraries, day care centers, airports, hospitals and supporting medical facilities, museums, fire stations, police stations, landfills, and prisons. The proposed street improvements within the right-of-way along Railroad Avenue at 13th Street and Lyons Avenue are within the Old Town Newhall Specific Plan area (See Figure 2-6, Old Town Newhall Specific Plan). The Specific Plan encourages mixed -use and transit -oriented development in the historic community of Newhall, in order to promote new investment, spur economic development, and create new residential opportunities in this area. While the public right-of-way does not fall within a specific zone classification, the properties adjacent to the Project Site boundaries along Lyons Avenue are designated as Urban Center (UC) by the Specific Plan. The UC zone is applied to the central portions of the downtown area appropriate for a wide range of land uses in buildings averaging 2.5 stories in height, with ground floor uses including retail, offices, and restaurants, and upper floors accommodating offices or residential. Lodging, restaurant, entertainment, and civic uses are also encouraged. The properties fronting the right- of-way adjacent to the Project Site along west side of Railroad Avenue at 13th Street are designated as Corridor (C). The Corridor designation is slated for more automobile -oriented commercial uses. These areas would be developed to allow "automobile -related development in a way that is consistent with and complimentary to the adjacent Downtown development." Specifically, buildings would be closer to the street with pedestrian considerations applied to transition to the more literal pedestrian environment of the Downtown. Buildings are envisioned as one to two stories tall with little or no housing. Lyons Avenue/Dockweiler Drive Extension Project 2.

Chapter 17.39, Section 020, of the Santa Clarita Municipal Code (SCMC) establishes the PCSSD design standards in order to protect, preserve and enhance the secluded, rural and equestrian character of the Placerita Canyon community. Additionally, the PCSSD serves to help mitigate the cumulative impacts of development and ensure reasonable access to public riding and hiking trails. The North Newhall Area was established in order to stimulate development and redevelopment activities in the area north of Old Town Newhall. The SCMC establishes guidelines for the NNA to ensure that it provides buffering, transitional densities and protection for the existing developed areas and not intrude in or change the character of Placerita Canyon. Additionally, a Mixed Use Overlay Zone was adopted to encourage a mix of residential, commercial, employment, and institutional uses along the Newhall Avenue and Lyons Avenue corridors. The Mixed Use Overlay Zone serves to revitalize older commercial corridors, increase opportunities for infill housing, and encourage development that creates pedestrian -oriented neighborhoods. 2.4 SURROUNDING LAND USES The portion of the Project Site to the east of the intersection of Railroad Avenue and Lyons Avenue (across Newhall Creek), is bounded the Old Town Newhall Library and commercial uses to the west, across Railroad Avenue (See Figure 2-7, View 1, 2 and 3), commercial and industrial uses to the north (See Figure 2-7, View 4), the Newhall Metrolink Station to the south (See Figure 2-7, View 5), residential properties to the east and a landscape nursery to the east and southeast.

The Lyons Avenue/Dockweiler Drive extension is proposed to be one of the primary east -west arterials through the City of Santa Clarita that would provide a through connection from Sierra Highway to Railroad Avenue. The Proposed Project includes the extension of Lyons Avenue from Railroad Avenue southeast to the proposed connection with Dockweiler Drive, the addition of a new at -grade railroad crossing east of the Railroad Avenue and Lyons Avenue intersection, and the extension of Dockweiler Drive from the approved alignment of Dockweiler Drive at The Master's University site (The Master's University extension of Dockweiler Drive through The Master's University property was evaluated under a separate EIR'), and northwest to connect with the intersection of Arch Street and 12a' Street. The Proposed Project would extend Lyons Avenue from its existing terminus at Railroad Avenue, eastward to Dockweiler Drive to provide a T-intersection at Dockweiler Drive. The Proposed Site Plan is depicted in Figure 2-9. In coordination with the proposed Railroad Bike Path project, the new Dockweiler Drive extension will result in creating a vital Complete Street link between the communities to the east of the railroad/ Newhall Creek (including the Master's University) and Old Town Newhall and Metrolink station. The Proposed Project also includes the closure of an at -grade railroad crossing at the intersection of 13a' Street and Railroad Avenue. The intersection at 13a' Street would be modified, removing the northbound right turn lane and southbound left turn lane and restricting the eastbound through movement. The Proposed Site Plan for the at -grade railroad closure at 13a' Street and Railroad Avenue is depicted in Figure 2-10. 1 The Master's College Master Plan Draft EIR, dated July 2008, and Final EIR, dated October 2008.

The proposed at -grade crossing at Lyons Avenue will improve traffic movements and circulation. Roadway construction will include a new bridge crossing over Newhall Creek and would necessitate embankment protection on both sides of the creek. The Newhall Creek improvements will be designed in accordance with current regulatory and State permitting agencies. Street improvements would include: • Installation of a new traffic signal at Lyons and Railroad Avenues; • Installation of intersection improvements at the Arch Street/ 12lb Street/Placerita Canyon and proposed Dockweiler Drive alignment. For purposes of this analysis, the following three intersection configurations were evaluated as potential design options: o A 5-way intersection configuration as shown in Figure 2.11: Option A — 5-Legged Intersection. o A traffic circle as shown in Figure 2.12: Option B, Traffic Circle. o A 3-legged intersection as shown in Figure 2.13: Option C, 3-Legged Intersection. • Street widening for Lyons and Railroad Avenues; • Installation of raised median island on both streets; • New signing, striping and legends such as monument signage to properly identify the entrance to the Placerita Canyon community as a residential community with no through access. Railroad improvements would include: • New railroad signal house; • Crossing Panels; • Advance Preemption and railroad signal design; • Pedestrian gates (4); • Railroad related signing, striping and legends; • Blank out sign for northbound traffic making right turn into the eastbound Lyons Avenue; • New fencing for railroad; • New driveway to access railroad property for maintenance; • New vehicular gates (6); • New railroad loops. The proposed alignment and roadway extension is part of the City's General Plan and consistent with the goals of the Old Town Newhall Specific Plan, Santa Clarita Valley Consolidated Traffic Model (SCVCTM), and the Compass Blueprint Plan. The extension of the proposed roadway (Lyons Avenue) is designated as a Secondary Highway per the City of Santa Clarita's General Plan.

PARKER Figure 2-13 ENVIRONMENTAL CONSULTANTS Option C - 3 Legged Intersection City of Santa Clarita August 2017 is consistent with the approved Master's University Master Plan, in which Dockweiler Drive was re- designated as a 4-lane Secondary Highway. The proposed roadway from the Arch Street/12a' Street/Placerita Canyon/Dockweiler Drive intersection to the future intersection of Lyons Avenue and Dockweiler Drive will be a two-lane facility with a 13-foot landscaped parkway/sidewalk on each side. The proposed roadway from the Lyons Avenue and Dockweiler Drive intersection to the Master's University property line will be a 2-lane facility with a 12-foot raised landscaped median, and 13-foot parkway/sidewalk on each side. The median lanes will be 12 feet wide and the parking lanes 9 feet wide with a 6-foot bike lane. The parking lanes will be capable of being converted into a travel lane to create an ultimate 4-lane facility in compliance with the City's General Plan. The typical right-of-way (R/W) width will be 92 feet. The Proposed Project would also include the closure of an at -grade crossing at the intersection of Railroad Avenue and 13a' Street. Street improvements at the 13a' Street and Railroad Avenue at -grade railroad crossing intersection are illustrated in Figure 2.10, 13a' Street Crossing Closure and would include: • Modify existing traffic signal for a T-intersection operation • Street construction with new curb and gutter and related striping, signing, and legends • New landscaping along 13a' Street near railroad property • Modify signing, striping and legends on 13a' Street and Railroad Avenue to reflect new intersection and new design for 13a' Street Railroad improvements associated with the closure of the 13a' Street at -grade crossing would include: • Remove railroad signal house and modify railroad signal interference with the traffic signal • Remove crossing panels • Modify railroad signal and related work • Remove railroad related signing, striping and legends • Remove all railroad related signals in coordination with City's traffic signal • New fencing for railroad • New driveway to access railroad property for maintenance Construction The construction of the Proposed Project east of Railroad Avenue will join existing roadways in the Placerita Canyon and Newhall communities. Connection points are proposed at the Arch Street/12a' Street intersection, Railroad Avenue and Lyons Avenue, and the proposed Dockweiler Drive extension at The Master's University. See Figures 2.11 through 2.13 for the three optional design configurations for the Arch Street/12a' Street/Placerita Canyon/Dockweiler Drive intersection.

PARKER Figure 2-18 ENvtRONMENTAL CON 5ULTANrs Dockweiler Drive Study Area - Adjacent Properties Map City of Santa Clarita August 2017 2.6 PROJECT OBJECTIVES The purpose of the proposed project is to achieve CPUC approval of an at -grade rail crossing at the current terminus of Lyons Avenue and the Southern Pacific Railroad line and extend a through roadway connection from Lyons Avenue to Dockweiler Drive. The Applicant's stated objectives for the proposed project are as follows: • Implementation of the goals of the Circulation Element of the Santa Clarita General Plan, including the crossing at Lyons Avenue and the extension of Lyons Avenue/Dockweiler Drive; • Improve roadway level of service and circulation network; Provide a safe and efficient at -grade rail crossing that meets the standards of the California Public Utilities Commission (CPUC); • Provide sufficient information for CPUC application and approval of the proposed crossing; • Improve pedestrian and vehicle railroad safety by eliminating an existing substandard at -grade rail crossing at 13a' Street and replacing it with a more advanced and enhanced at -grade rail crossing at Lyons Avenue; • Reduce vehicle miles traveled by creating a more direct route for motorists, eliminating circuitous driving patterns. • Provide greater connectivity between Old Town Newhall, Placerita Canyon, The Master's University and the residents that live along Dockweiler Drive; • Provide an economic stimulus to Old Town Newhall with enhanced connectivity to the Old Town Newhall area; and • Provide an enhanced gateway to Placerita Canyon. 2.7 DISCRETIONARY APPROVALS Lead Agency Under CEQA, the public agency that has the principal responsibility for carrying out or approving a proposed project is referred to as the "Lead Agency" (State CEQA Guidelines Section 15367). For purposes of the Dockweiler Drive Alignment Project, the City of Santa Clarita is identified as both the project proponent ("Applicant") and Lead Agency. The proposed project would be part of the City's Capital Improvement Program. The City Council is the City's decision -making body and is responsible for approving projects to be built within City limits. Prior to approving the Proposed Project, the City Council must certify that (1) this EIR has been reviewed and considered; (2) the EIR has adequately analyzed the potential impacts of the proposed project; (3) it has been completed in compliance with CEQA, the State CEQA Guidelines, and the City's Environmental Guidelines; and (4) it reflects the independent judgment of the City Council. The Proposed Project would also require the approval of an Oak Tree Permit and Hillside Review Permit at such time as development occurs or when funding of roadway construction becomes available. In order to allow for the proposed development to occur, the Proposed Project would require an Oak Tree Permit and a Hillside Review Permit. Depending on the approval of the Proposed Project or one of the Project Alternatives evaluated within the scope of the EIR, the oak tree permit would be required to determine the Lyons Avenue/Dockweiler Drive Extension Project 2. Project Description SCH No. 2013082016 Page 2-28 City of Santa Clarita August 2017 oak tree impacts at the time of project development. The Hillside Review Permit would permit the grading necessary to construct the roadway. These entitlements will be obtained at such time as the proposed alignment is approved and roadway funding is available to implement the Project. Because it is not known at this time when the project would be funded or built and permits expire after two years, it was determined to be more cost effective to wait until such time as construction of the roadway is imminent to secure permits for the project. Additional ministerial actions, such as grading permits, would be required by the City prior to actual grading and construction of the proposed roadway extension. Responsible Agencies Public agencies other than the Lead Agency, that have discretionary approval power or regulatory oversight over the proposed project or project activities are considered "Responsible Agencies" (State CEQA Guidelines Section 15381). If the City approves the Proposed Project, subsequent implementation of various project components could require discretionary approval authority from the following responsible agencies: • California Public Utilities Commission (CPUC); • Southern California Rail Authority; • Los Angeles County Metropolitan Transportation Authority (LACMTA); • California Department of Fish and Wildlife (CDFW); • California Regional Water Quality Control Board (RWQCB); • Los Angeles County Fire Department (LACFD): • Los Angeles County Department of Public Works (LAPW) • South Coast Air Quality Management District (SCAQMD); • U.S. Fish and Wildlife Service (USFWS); and • U.S. Army Corps of Engineers (USACE). Lyons Avenue/Dockweiler Drive Extension Project 2. Project Description SCH No. 2013082016 Page 2-29 3. OVERVIEW OF ENVIRONMENTAL SETTING 3.1 INTRODUCTION This section provides an overview of the Project Site's regional and local setting and describes the basis for the discussion of cumulative impacts addressed in Section 4, Environmental Impact Analysis. More detailed information on the environmental setting as it relates to each of the environmental issues analyzed in the scope of this EIR are included in Sections 4.1 through 4.9, respectively. 3.2 ENVIRONMENTAL SETTING Regional Setting The Project Site is located in Los Angeles County within the City of Santa Clarita. Regional access to the Project Site is provided by State Route 14 Freeway (SR-14), located east of the Project Site, and Golden State/Santa Ana Freeway (I-5), located west of the Project Site. Local Setting The Project Site is located at the intersection of Lyons Avenue and Railroad Avenue and extends eastward towards the General Plan alignment for Dockweiler Drive at The Master's University, and northwest towards the intersection of Arch Street and 12th Street. The Project Site also includes the closure of an at -grade crossing at the intersection of Railroad Avenue and 13th Street. The limits for the Lyons Avenue/Dockweiler Drive extension are from Railroad Avenue on the west to the future Master's University Master Plan Dockweiler extension to the east. Surrounding Land Uses The Project Site is located immediately southwest of the Placerita Canyon community and east of the Old Town Newhall community. The portion of the Project Site to the east of the intersection of Railroad Avenue and Lyons Avenue is bounded by commercial and industrial uses to the north, a landscape nursery to the south east, the Newhall Metrolink Station to the south and the Old Town Newhall Library and commercial uses to the west, across Railroad Avenue. The portion of the Project Site to the east of the intersection of Railroad Avenue is bounded by undeveloped land to the north, commercial and industrial uses to the east, Newhall Creek to the south and one-story commercial buildings to the west, across Railroad Avenue. Project Site The existing Project Site consists of improved segments of Railroad Avenue and Lyons Avenue roadways and undeveloped land to the east extending towards Dockweiler Drive. The west end of the Project Site encompasses portions of Newhall Creek. The portion of the Project Site that includes the intersection of Railroad Avenue and 13th Street is developed with existing road surface and an at -grade crossing. The Lyons Avenue/Dockweiler Drive Extension Project 3. Environmental Setting SCH No. 2013082016 Page 3-1 City of Santa Clarita August 2017 Union Pacific/Metrolink Railroad line crosses the Project Site at the intersection of Railroad Avenue and Lyons Avenue at the intersection of Railroad Avenue and 13a' Street. Aesthetics/Views Views within the vicinity of the Project Site are characterized by the natural and built environment surrounding the area. The existing viewsheds in the project area are defined primarily by commercial land uses in Old Town Newhall, to the west across Railroad Avenue, and views of the Santa Susana Mountains to the south and west, the San Gabriel Mountains to the southeast and Sierra Pelona Mountains to the north. Viewsheds from the Project Site of the Placerita Canyon residential community and The Master's University are largely blocked by steep undeveloped terrain and a ridgeline to the east and southeast. Viewsheds to the north of the Project Site include relatively flat undeveloped open space followed by smaller hills and ridgelines in the background. Portions of the Project Site are visible from the Old Town Newhall area from Lyons Avenue and along Railroad Avenue and from several residential properties within Placerita Canyon near Aden Avenue. The Project Site is visible from The Master's University, the Metrolink Station and recreation trails, located south and southeast of the Project Site. The Project site is also visible from portions of Market Street, south of the Project Site. Air Quality The Project Site is located within the South Coast Air Basin (Basin). The Basin includes all of Orange County and the non -desert portions of Los Angeles, San Bernardino, and Riverside Counties. The regional climate within the Basin is considered semi -arid and is characterized by warm summers, mild winters, infrequent seasonal rainfall, moderate daytime onshore breezes, and moderate humidity. The air quality within the Basin is primarily influenced by a wide range of emissions sources (e.g., dense population centers, heavy vehicular traffic, and industries) and meteorology. The South Coast Air Quality Management District (SCAQMD) is the agency principally responsible for comprehensive air pollution control in the Basin. The SCAQMD divides the Basin into 38 source receptor areas (SRAs) in which 38 monitoring stations track the various concentrations of air pollutants in the region. The Project Site is located within SRA 13, which covers the Santa Clarita Valley. SCAQMD air quality monitoring Station No. 090 is located at 22224 Placerita Canyon Road and is located within the boundaries of the Project Site's northern alignment of Dockweiler Drive extending to Arch Street. This station currently monitors emission levels of CO, NO2, 03, PMIo, PM25, and VOC. The Basin in in attainment for CO. From 2010 to 2013, the ambient air quality levels within SRA 13 exceeded the state standard for 03 by a total of 124 days; measured NO2 concentrations were within the state standards for all four years; and PMIo emissions exceeded the state standard only one day in the four year reporting history. Biological Resources The analysis presented in the Biological Resources section is based on the Biological Resources Assessment, Jurisdictional Delineation and Impact Assessment, Dockweiler Road Extension Project, Lyons Avenue/Dockweiler Drive Extension Project 3. Environmental Setting SCH No. 2013082016 Page 3-2 City of Santa Clarita August 2017 Santa Clarita, California, prepared by Impact Sciences, Inc., dated April 2015 ("Biological Assessment") The Biological Assessment is provided in Appendix D of this Draft EIR. Vegetation Communities Eight vegetation communities occur on the Project Site, which includes: California Sagebrush -California Buckwheat Scrub, Disturbed California Sagebrush- California Buckwheat Scrub, Scale Broom—Mulefat scrub, Scalebroom Scrub, Active Channel, Exotic Trees, Developed/ Ornamental Landscaping, and Cleared. Site grading plans indicate that within the Project Site 2.32 acres of vegetation would be removed (100 percent of the vegetation resources present). Of the vegetation communities impacted Disturbed California Sagebrush -California Buckwheat Scrub is the dominant plant community present by area and approximately 0.63 acre of this habitat would be lost through site grading and project implementation. Wildlife Wildlife diversity on the Project Site is relatively low. The only reptile observed on site was the side - blotched lizard (Uta stansburiana). Tracks, scat, burrows, and other signs observed indicate the presence of California ground squirrel (Spermophilus beecheyi) and Botta's pocket gopher (Thomomys bottae). Common bird species recorded during the field surveys included mourning dove (Zenaida macroura), American crow (Corvus brachyrhynchos), California towhee (Melozone crissalis), house finch (Haemorhous mexicanus), and Say's phoebe (Sayornis saya). All of these species are relatively tolerant of human encroachment. Several additional avian species are expected to occur on site seasonally. Small rodents including Botta's pocket gopher (Thomomys bottae) and deer mouse (Peromyscus maniculatus) are likely present and evidence of California ground squirrel (Otospermophilus beecheyi) and evidence of coyote (Canis latrans) were observed. Wildlife Movement Newhall Creek does provide, a connection between the Santa Clara River and the Angeles National Forest to the southeast. Although, much of the length of the creek occurs adjacent to dense development and wildlife activity is expected to be somewhat limited, Newhall Creek is considered part of a wildlife movement or migration corridor that connects larger areas of natural open space. Special -Status Plant and Animal Resources The only special -status plants observed during the field investigations were two coast live oaks. No other special -status plants are considered to have a high potential for occurrence within the Project Site. Native oak trees are protected under City of Santa Clarita Oak Tree Ordinance (Ordinance No. 89-10, passed by the City Council on April 25, 1989). A permit is required for encroachment into the Protected Zone, defined as 5 feet outside the dripline and further defined as extending no less than 15 feet outward from the trunk of an oak tree. No special -status wildlife species were directly observed during field investigations conducted on the Project Site or area. Although Newhall Creek traverses the Project Site, it is considered a seasonal Lyons Avenue/Dockweiler Drive Extension Project 3. Environmental Setting SCH No. 2013082016 Page 3-3 City of Santa Clarita August 2017 drainage, and it is apparent within the Project Site, when flows do occur, they are rapid enough to scour the channel. The Silvery legless lizard (Anniella pulchra pulchra), is a small lizard is often mistaken for a snake or worm since, as it has no limbs. This special -status reptile is considered to have a moderate potential to occur on site. The Silvery legless lizard spends most of its life below surface soils. It is most commonly found in and around the roots of trees and shrubs, often beneath leaf litter where its prey is most abundant. This species is rarely observed unless one actively seeks it out. Though apparently very dry at the surface, some of areas within the Project Site may have sub -surface soils with the moisture content necessary to support this species. Therefore the Silvery legless lizard is considered to have a moderate potential for occurrence on the proposed Project Site. Jurisdictional Waters, Streambed, and Riparian Resources Based on field investigations, a small area of narrow -leaf willow thicket (300 square feet or 0.007 acre) is present. According to the wetland definition at the State level, narrow -leaf willow thicket present on -site would not meet the criteria of wetland as defined by the State of California. While narrow -leaf willow is a hydrophyte, there is no evidence of continuous or recurrent saturation of the upper substrate and no evidence of anaerobic conditions are present. Two jurisdictional features do occur within the Project Site and area. Newhall Creek and a small ephemeral drainage that is a tributary to Newhall Creek occur on the Project Site and fall under the jurisdiction of the CDFW. Although these jurisdictional features do not support riparian vegetation or sensitive wetland resources, Newhall Creek does support features that lie within the jurisdiction of CDFW. Cultural Resources Although portions of the Project Site are improved with roadways, the Project will include earthwork activities in areas that are currently undeveloped. As such, it is likely that the Proposed Project's earthwork activities may result in the accidental discovery of prehistoric or historic archaeological resources that may be located within the Project limits. The Cultural Resources section addresses the Proposed Project's potential to result in significant impacts upon cultural resources, including archaeological, paleontological and historic resources. On September 20, 2013, the South Central Coastal Information Center and the Vertebrate Paleontology Department at the Natural History Museum of Los Angeles County were contacted to provide expertise on cultural, archeological, and paleontological resources within the Project Site. With respect to cultural, archaeological, and paleontological resources, the analysis is based on feedback from the South Central Coastal Information Center (SCCIC), dated October 2, 2013, and from The Vertebrate Paleontology Department at the Natural History Museum of Los Angeles County, dated October 18, 2013 (See Appendix E of this Draft EIR). Geology and Soils The majority of the Geotechnical analysis is based on the Geologic and Geotechnical Report EIR-Level Review Of Road Alignments For Dockweiler Road and Lyons Avenue (The "Geotechnical Report') prepared by Allan E. Seward Engineering Geology, Inc., dated October 17, 2014 (See Appendix F of this Lyons Avenue/Dockweiler Drive Extension Project 3. Environmental Setting SCH No. 2013082016 Page 3-4 City of Santa Clarita August 2017 Draft EIR). As discussed in the Geotechnical Report and Section 4.5 of the Draft EIR, the proposed road alignments are located on the alluvial flood plain and hillside areas adjacent to Newhall Creek. The majority of the proposed road alignment for Lyons Avenue traverses undeveloped land, except for areas where artificial fill and railroad ballast have been placed to elevate and support the existing railroad double tracks. Dumped fill with abundant blocks of asphalt and concrete and other miscellaneous debris has been placed on the southwest bank of Newhall Creek, just northeast of the proposed at -grade railroad crossing. The proposed road alignment of Dockweiler Drive also traverses undeveloped land and a storage yard utilized by Los Angeles County Department of Public Works. The Project Site is covered with light to moderate growth of natural grasses and chaparral. Elevations at the site range from approximately 1255 to 1370 feet above mean sea level. Regional Geologic Conditions The Project Site is located within the central part of the Transverse Ranges geomorphic province of southern California, in the eastern portion of the Ventura Basin. The Ventura Basin has been tectonically down -warped in the geologic past to produce a large-scale synclinal structure in which a thick sequence of Cenozoic sediments has accumulated. In the vicinity of the proposed road alignments, much of the hillside area along the northeastern margin of Newhall Creek consists of bedrock of the Quaternary -age Pacoima Formation (Qp). The relatively flat flood plain southwest of Newhall Creek is underlain by sub - horizontal alluvium deposited (Qal). The Pacoima Formation and alluvial deposits are underlain by bedrock of the Plio-Pleistocene, nonmarine Saugus Formation (TQs). No faults or folds have been identified at the Project Site on the referenced published geologic map of the area. Seismic Considerations The Project Site lies within the seismically active southern California region. Earthquake -related hazards typically include ground rupture, ground shaking, and ground failure. Review of the Alquist-Priolo Earthquake Fault Zone Map for the Newhall Quadrangle, the Seismic Safety Element of the L.A. County General Plan, and the published Geologic Maps indicates that no active or potentially active faults traverse the Project Site. Review of the site topography and the aerial photographs did not reveal any lineaments or other indicators suggestive of faulting at the site. The nearest known active fault is the San Gabriel Fault, which is 3.7 km from the Project Site at its nearest point. Based on these distances, the probability of fault -related ground rupture at the Project Site is considered to be very low. Ground Failure Review of the referenced published geologic maps indicates that no landslides have been mapped at or adjacent to the Project Site. Review of aerial photographs lack geomorphic features that would indicate prior landslide movement. The majority of the Project Site is underlain by bedrock materials that are not susceptible to liquefaction. The alluvial soils present at the Project Site are not designated on the State of California Seismic Hazard Zone Map for the Newhall Quadrangle as a zone in which investigation of potentially liquefiable materials is required. The depth to historic high ground water at the site is greater than 50 feet. Based on the preceding factors, the potential for liquefaction and associated seismic settlements and lateral spreading is therefore considered very low. Lyons Avenue/Dockweiler Drive Extension Project 3. Environmental Setting SCH No. 2013082016 Page 3-5 City of Santa Clarita August 2017 Hydrology/Water Quality The Hydrology and Water Quality section is heavily based on the findings and conclusions as presented in the following technical report, Hydraulic and Scour Analysis Newhall Creek at Proposed Dockweiler Road Bridge, Newhall, California, prepared by Rivertech, Inc., dated February 2015 ("Hydraulic Report"), which is provided in Appendix G of this Draft EIR. The existing Project Site is generally pervious. The Project Site consists of improved segments of Railroad Avenue and Lyons Avenue roadways and undeveloped land to the east extending towards The Master's University and Arch Street. The west end of the Project Site encompasses portions of Newhall Creek and traverses a storage yard utilized by Los Angeles County Department of Public Works. Groundwater Review of historic ground water data from the Seismic Hazard Map for the Newhall Quadrangle, Water - Resources Investigation using Analog Model Techniques in the Saugus -Newhall Area, and LACFCD water well records indicates that historic high ground water levels are between 75 and 100 feet below the existing surface at the Project Site. In addition, ground water was not encountered in subsurface explorations to a depth of 50 feet in the alluvium for the adjacent Old Town Newhall Library. However, temporary perched ground water conditions may exist below Newhall Creek following periods of significant rainfall and runoff. A low potential exists for temporary, perched ground water conditions to develop within the bedrock of the Pacoima formation. Perched ground water can contribute to slope instability in natural slopes and cut slopes. To prevent build-up of water, subdrains are typically recommended in canyon areas in which fill will be placed and back drains for slopes that are to be constructed as Stability Fills or Buttress Fills. Due to the historic high ground water elevations and the elevated nature of portions of the road alignment, ground water is not expected to significantly affect the Proposed Project, provided the proposed grading is evaluated from a geotechnical standpoint during the design stage and the geotechnical recommendations are implemented during construction.' Inundation and Flooding The western portion of the roadway extension that crosses Newhall Creek, is located in a "Zone A", as indicated in the National Flood Insurance Rate Map for Los Angeles County, which indicates a special flood hazard area that is subject to inundation by the 1% annual chance flood (100-year flood) .2 As concluded in the Hydraulic Report, the existing Newhall Creek Channel does not have the capacity to convey the FIS 100-year and the Capital Flood flow rates. As a result, the 100-year model results show that a significant percentage of the flow spill out the main channel and flood the railroad, entering the Railroad Avenue.

Lyons Avenue/Dockweiler Drive Extension Project 3. Environmental Setting SCH No. 2013082016 Page 3-6 City of Santa Clarita August 2017 Land Use and Planning The existing Project Site consists of improved segments of Railroad Avenue and Lyons Avenue roadways and undeveloped land to the east extending towards Dockweiler Drive. The west end of the Project Site encompasses portions of Newhall Creek. The portion of the Project Site that includes the intersection of Railroad Avenue and 13a' Street is developed with existing road surface and an at grade crossing. The UP/Metrolink Railroad line crosses the Project Site east of the intersection of Railroad Avenue and Lyons Avenue Railroad and at the intersection of Railroad Avenue and 13a' Street. The portion of the Project Site to the east of the intersection of Railroad Avenue and Lyons Avenue is bounded by an industrial and commercial uses to the north, a landscape nursery to the south east, the Newhall Metrolink Station to the south and the Old Town Newhall Library and commercial uses to the west, across Railroad Avenue. The portion of the Project Site to the east of the intersection of Railroad Avenue is bounded by undeveloped land to the north, industrial and commercial uses to the east, Newhall Creek to the south and one-story commercial buildings to the west, across Railroad Avenue. Properties to the north of the Project Site are zoned MXN. Properties to the south of the Project Site are zoned Specific Plan (SP). Properties to the east of the Project Site are zoned Urban Residential 1 (UR1), Urban Residential 3 (UR3) and Public Institutional (PI). Properties to the west, across Railroad Avenue are zoned SP. The General Plan land use designation of the Project Site is Mixed Use Neighborhood (MXN). The General Plan states that areas with a MXN designation should be developed to create neighborhoods that combine residential uses with complementary commercial services, including retail and office uses. MXN zoned areas should be located in close proximity to public transit and provide roadway and trail linkages to adjacent development. The Project Site is located adjacent to the Old Town Newhall Specific Plan area, the Placerita Canyon Special Standards District (PCSSD), and is part of the North Newhall Area (NNA), which includes a Mixed -Use Overlay Zone. In addition, the Project Site is located in the City's Compass Blueprint Concept Plan (Concept Plan) area, which is a conceptual land use and circulation plan that guides development in the Newhall community north of Old Town Newhall and east of Railroad Avenue. Regional plans to which development must conform include the Southern California Association of Government's (SLAG) Regional Comprehensive Plan Guide (RCPG) and the South Coast Air Quality Management District's (SCAQMD) Air Quality Management Plan (AQMP). The City has identified the extension of Lyons Avenue to Dockweiler Drive, across the existing Metrolink line, as one of five key transportation projects. The extension of Dockweiler Drive is identified in the Circulation Element as a major new roadway. The alignment is part of the City's current General Plan and consistent with the goals of the Specific Plan, Santa Clarita Valley Consolidated Traffic Model (SCVCTM), and the Concept Plan. The extension would provide a connection from Railroad Avenue to Sierra Highway. Construction of the extension would include a new four -lane highway, connecting Dockweiler Drive from Railroad Avenue to Leonard Tree Lane. Lyons Avenue/Dockweiler Drive Extension Project 3. Environmental Setting SCH No. 2013082016 Page 3-7 City of Santa Clarita August 2017 Noise Ambient noise levels within the Project Area range from 56.6 dBA Leq at the residential roadway on Aden Avenue to 72.3 to 76.3 dBA along Railroad Avenue at 13a' Street and Lyons Avenue. Noise measurements recorded at Aden Avenue represent typical residential area noise volumes and were influenced by residential activities such as a residential construction remodel, barking dogs, a delivery truck and an airplane flying overhead. Noise levels along Railroad Avenue were slightly higher (72.3 to 76.3 dBA Leq), and were attributable to the roadway volumes. Existing roadway noise levels for selected roadway segments in the vicinity of the Project Site were modeled based on average daily traffic volumes and the roadway noise prediction modeling methodology of the Federal Highway Administration (FHWA) Highway Noise Prediction Model (FHWA-RD-77-108). The modeling data is provided in Appendix I to this Draft EIR. The traffic volumes for each roadway segment are provided in the project Traffic Study (see Appendix I to this Draft EIR). The estimated average 24-hour hour community noise equivalent noise levels (CNEL) for the selected roadway segments are within a range of 64.5 to 75.3 dBA under existing roadway conditions. Transportation and Circulation The traffic analysis is based on the Traffic Study titled, Traffic Impact Analysis: Dockweiler Drive Alignment Project, Santa Clarita, CA, prepared by David Evans & Associates, Inc. dated May 2, 2016. The scope and methodology of this analysis was determined in conjunction with the City of Santa Clarita. The complete Traffic Study is included in Appendix H to this Draft EIR. The extension of Lyons Avenue to Dockweiler Drive across the existing Metrolink line has been identified by the City as one of five key transportation projects. The alignment is part of the City's General Plan and consistent with the goals of the Old Town Newhall Specific Plan, Santa Clarita Valley Consolidated Traffic Model (SCVCTM), and the Compass Blueprint Plan. Regional Access Sierra Highway and the SR-14 (Antelope Valley) Freeway provide a boundary for the study area along the eastern side. Through traffic access on Placerita Canyon Road is restricted with a gate entrance west of Sierra Highway. Placerita Canyon Road currently is the primary connection to the Master's University and residents to the north. Newhall Avenue on the southern boundary of the study area provides a direct connection for cross valley traffic and connects Sierra Highway and Railroad Avenue. The UP/Metrolink Railroad line restricts access to the west with three existing at -grade railroad crossings located at 13a' Street, Market Street, and Newhall Avenue. Existing Street System Dockweiler Drive is designated as an east -west Secondary Highway from Sierra Highway to Railroad Avenue on the City of Santa Clarita Circulation Map Joint Highway Plan. The existing portion of Dockweiler Drive consists of one and two lanes in each direction with a landscaped median and limited parking throughout the study area. Dockweiler Drive is used as the primary access to single- and multi- family residences. Lyons Avenue/Dockweiler Drive Extension Project 3. Environmental Setting SCH No. 2013082016 Page 3-8 City of Santa Clarita August 2017 State Route 14 Freeway (SR 14) provides regional access within the study area. The freeway is a four - lane (two in each direction) facility with interchange access at Placerita Canyon Road and Newhall Avenue. Lyons Avenue is designated as an east -west major highway east of Railroad Avenue and Secondary Highway west of Railroad Avenue on the City of Santa Clarita Circulation Map Joint Highway Plan. Three lanes in each direction are provided with traffic signals and left turn channelization at major intersections. Newhall Avenue is designated as a north -south secondary highway from Lyons Avenue to Railroad Avenue with one lane in each direction. From Railroad Avenue to SR-14, Newhall Avenue is designated as a major highway with three northbound lanes and three southbound lanes south of Railroad Avenue. Newhall Avenue roadway designation is identified on the City of Santa Clarita Circulation Map Joint Highway Plan. Railroad Avenue (formerly San Fernando Road) is a north -south major highway from Magic Mountain Parkway to Lyons Avenue and a secondary highway from Lyons Avenue to Newhall Avenue. This roadway provides two lanes in each direction and limited parking throughout the study area. Railroad Avenue roadway designation is identified on the City of Santa Clarita Circulation Map Joint Highway Plan. Sierra Highway is an old alignment of SR-14 from Los Angeles to Mojave. It is designated as a north - south major highway on the City of Santa Clarita Map Joint Highway Plan. It is a four lane (two in each direction) with traffic signals and left turn channelization at major intersections. Placerita Canyon Road is an east -west local roadway. This roadway provides a gate at the eastern entrance. The gate provides restrictive access to residents of the Placenta Canyon neighborhood. 13`h Street is an east -west unimproved local roadway. This roadway provides access to The Master's University and the Placenta Canyon neighborhood via its intersection with Railroad Avenue. One lane is provided in each direction. Existing Transit Service The Santa Clarita Valley's circulation system is a comprehensive transportation network of roadways, multi -use trails, bicycle paths, bus transit, and commuter rail. This network provides mobility options to Santa Clarita Valley residents and businesses. A major component in the development of the Santa Clarita Valley is the inclusion of alternative travel modes and support facilities. These facilities include efficiency and capacity of existing systems, by promoting mixed -use development near transit facilities. Bicycle lanes and accessibility of bike paths are a fundamental component to a comprehensive transportation network. Existing Peak Hour Levels of Service The level -of -service (LOS) is based on the average delay of vehicles at the intersections. Table 4.9-2, of Section 4.9, Transportation and Traffic, provides the LOS thresholds for roundabout intersections per the Lyons Avenue/Dockweiler Drive Extension Project 3. Environmental Setting SCH No. 2013082016 Page 3-9 City of Santa Clarita August 2017 HCM 2010 methodology. The City of Santa Clarita preferred maximum acceptable level of service on arterial roads is LOS E. The City of Santa Clarita desired maximum acceptable level of service on residential neighborhood roads is LOS C or better. Under existing conditions, most intersections are operating at LOS E or better. There are two intersections that are currently operating at LOS F, they are: Sierra Highway and SR-14 Southbound Ramps and SR-14 Southbound Ramps and Newhall Avenue. 3.3 CUMULATIVE PROJECTS CEQA requires that Environmental Impact Reports analyze "cumulative impacts," defined in CEQA Guidelines Section 15355 as "two or more individual effects which, when considered together, are considerable or which compound or increase other environmental impacts." In addition, CEQA Guidelines Section 15130 indicates that the analysis of cumulative impacts need not be as in-depth as what is performed relative to the proposed project, but instead is to "be guided by the standards of practicality and reasonableness." The cumulative impacts analysis considers the anticipated impacts of the Proposed Project along with reasonably foreseeable growth. According to CEQA Guidelines Section 15130(b)(1), reasonably foreseeable growth may be based on:3 • A list of past, present, and probable future projects producing related or cumulative impacts; and/or • A summary of projections contained in an adopted general plan or related planning document, or in a prior environmental planning document which has been adopted or certified, which described or evaluated regional or area -wide conditions contributing to the cumulative impact. Cumulative study areas are defined based on an analysis of the geographical scope relevant to each particular environmental issue. Therefore, the cumulative study area and the applicable related projects for each individual environmental impact may vary. For example, a cumulative visual impact generally could only affect the area within the view of a project site, while a cumulative air quality impact could affect the entire South Coast Air Basin. City of Santa Clarita - Projections for Population and Households For purposes of the cumulative impact analysis, this Draft EIR references the City of Santa Clarita General Plan "One Valley One Vision," which provides a summary of growth projections for the Santa Clarita Valley. The Future Year 2035 traffic volumes were provided by the City of Santa Clarita using the Santa Clarita Valley Consolidated Traffic Model (SCVCTM) for the Buildout Year. Other Area Projects anticipated to be constructed by Year 2035 have been incorporated into the SCVCTM, and account for expected growth. The buildout includes construction of future roadways including Magic Mountain Parkway from Railroad Avenue to Via Princessa, and Via Princessa between Claibourne Lane and Sheldon Avenue, and Santa Clarita Parkway. The future buildout SCVTM model also includes the proposed conceptual development of the North Newhall Area. 3 Clarification based on Communities for a Better Environment v. California Resources Agency, 2002. Lyons Avenue/Dockweiler Drive Extension Project 3. Environmental Setting SCH No. 2013082016 Page 3-10 City of Santa Clarita August 2017 With respect to growth projections for the Santa Clarita Valley, the Land Use elements notes that the projections generated from the traffic analysis zone (TAZ) analysis represent staff s best efforts to achieve a realistic vision of actual build -out potential for the planning area. In preparing the One Valley One Vision land use projections, staff acknowledged that portions of the planning area are already largely developed, and that the City's General Plan and the County's Area Plan are not based on a "clean slate" of vacant, undeveloped land. Existing uses and development patterns must be recognized in planning for projects and development of new uses. The methodology used by staff to develop these detailed demographic projections is discussed in further detail in the City's General Plan Land Use Element.

AESTHETICS 4.1.1 INTRODUCTION This section evaluates the potential impacts of the Proposed Project on aesthetics, views and vistas, visual character, and light and glare in the Project area. Aesthetics generally refers to visual resources and the quality of what can be seen, or overall visual perception of the environment, and may include such characteristics as building height and mass, development density and design, building condition (i.e., blight), ambient lighting and illumination, vegetation/landscaping, natural landforms, and open space. Views and vistas refer to visual access and obstruction of prominent visual features, including valued visual landmarks and panoramic vistas. Visual character may be defined by the different elements of natural features such as topography, geologic features, water features, or natural vegetation, or urban features such as land use patterns and density, urban form and design, building mass, and any historic resources within the locale. The analysis of light and glare impacts addresses the effects of nighttime illumination and daytime glare on adjacent land uses. 4.1.2 ENVIRONMENTAL SETTING Existing Visual Characteristics and Views The existing visual character of the project area is largely defined by a mix of natural and built features within the environment. The natural environment surrounding the Project Site at Lyons Avenue and Railroad Avenue, and the portion of the Project Site at Railroad Avenue and 13a' Street, is composed of hillsides and ridgelines with diverse topography, open space, the Newhall Creek in the foreground, and scenic mountains and ridgelines in the background. The aesthetic features that characterize the project area includes the rural, equestrian -oriented residential community of Placerita Canyon, located east of the Project Site, and Old Town Newhall, located west of the Project Site, which is primarily developed with commercial retail land uses along Main Street and Lyons Avenue and multi -family and single-family residential uses north and south of Lyons Avenue. The Newhall Library is a prominent public building and architectural feature located on the north side of Lyons Avenue just to the west of the Project Site. Views of the Project Site The Project Site consists of improved roadway segments of Railroad Avenue and Lyons Avenue and undeveloped land with moderate to steep topography to the east extending towards Dockweiler Drive. The most prominent natural feature in the vicinity of Project Site is Newhall Creek and the southern ridgeline of Placerita Canyon. Newhall Creek, which has a north -south orientation within the area of the Project Site, is a prominent natural feature, but is predominately concealed from view by topography, the elevated railroad right of way, and natural vegetation. The east -west trending ridgeline located to the immediate south of the Project Site, which is identified in the City's General Plan as a significant ridgeline, extends from The Master's University upper campus parking lot at its highest point and gradually declines in elevation westward towards the Project Site. The location of the ridgeline relative to Lyons Avenue/Dockweiler Drive Extension Project 4.1 Aesthetics SCH No. 2013082016 Page 4.1-1 of Santa Clarita August 2017 the grading footprint of the proposed roadway alignment is identified in Figure 4.1-1, Significant Ridgelines. Within the confines of the Project Site, the elevation of the ridgeline is 1,280 feet above mean sea level (msl) at the approximate toe of the ridgeline to 1,339 msl at the western limit of the alignment where it connects to The Master's University segment of the future Dockweiler alignment. It should be noted that the eastern segment of the Dockweiler alignment was previously approved under a separate project entitlement for The Master's University in 2009, which included a Ridgeline Alteration Permit for the eastern segment of this ridgeline.' With respect to natural scenic resources, two coast live oaks have been identified within this portion of the Project Site. (See Section 4.3 Biological Resources and Appendix D of this Draft EIR). Native oak trees are recognized as a visual aesthetic and natural resource protected under City of Santa Clarita Oak Tree Ordinance (Ordinance No. 89-10, passed by the City Council on April 25, 1989)and the City's Oak Tree Preservation and Protection Guidelines (adopted September 11, 1990). The City of Santa Clarita requires that all potential impacts to oak trees be preceded by an application to the City that includes a detailed oak tree report and that loss of or damage to protected oaks be mitigated at a minimum 2:1 ratio. The Project Site is prominently visible from the Old Town Newhall area from Lyons Avenue and along Railroad Avenue (See Views 1 and 2 of Figure 4.1-2) and from several residential properties within Placerita Canyon near Aden Avenue and is intermittently visible from The Master's University, the Metrolink Station, recreation trails, located south and southeast of the Project Site, and from portions of Market Street, south of the Project Site (See Views 3 and 4 of Figure 4.1-2). Proximately visible at the terminus of Lyons Avenue is an outdoor advertising billboard. (See View 1 in Figure 4.1-2). The billboard signage is approximately 10 feet by 30 feet in area and is mounted on a monopole approximately 20-25 feet above grade. The sign is illuminated during evening hours. The eastern sidewalk along Railroad Avenue is landscaped and separated from the elevated railroad right-of- way easement by a chain link fence (See Figure 4.1-2, View 2). The Project Site is visible from Market Street to the south and the surface parking lot of the Jan Heidt Metrolink Station. From this vantage, the ridgeline and natural open space vegetation on the east side of Newhall Creek is proximately visible in the background. Views of the Project Site from this vantage point are depicted in Figure 4.2-2, Views 3 and 4. Views of Surrounding Properties The Project Site is located immediately southwest of the Placerita Canyon community and east of the Old Town Newhall community. Land uses in the vicinity of the Project Site include commercial and industrial uses to the north fronting 13a' Street, 12t'' Street, and Arch Street, a landscape nursery to the south east, 1 The Master's College Master Plan Project Master Case No. 04-496: Master Plan 07-001, General Plan Amendment 04-009, Zone Change 04-006, Tentative Tract Map 66503, Conditional Use Permit 04-031, Ridgeline Alteration Permit 07-001, Hillside Review 04-010, Oak Tree Permit 04-050 Environmental Impact Report, SCHNo. 2006101171.

Regulatory Setting Aesthetics is addressed in various sections of the City of Santa Clarita's General Plan and Municipal Code. Each element of the General Plan contains goals, objectives, and policies to map out the development approach for the City. General aesthetic appearance goals, policies, and objectives are discussed below in the General Plan Conservation and Open Space Element and Municipal Code's Hillside Development Ordinance. General Plan Conservation and Open Space Element The Conservation and Open Space Element establish a framework to ensure preservation of an open space greenbelt around large portions of the Santa Clarita Valley, in addition to preserving water quality, historic and cultural resources, scenic views, and providing recreational facilities to enhance the quality of life for residents. Preservation of scenic and accessible open spaces around the urbanized portions of the Valley, and between neighborhoods and districts, contributes to community character and the distinctive sense of place. The Conservation and Open Space Element includes goals, objectives and policies for the following resources: soils and geological resources; water, including water supply, quality and conservation; biological resources; cultural and historical resources; air quality, energy conservation and climate change; parks, recreation, and trails; and open space conservation. Hillside Development Ordinance Section 17.51.080 of the Santa Clarita Municipal Code establishes the Hillside Development Ordinance in order to regulate the development and alteration of hillside areas, to minimize the adverse effects of hillside development and to provide for the safety and welfare of the citizens of the City of Santa Clarita while allowing for the reasonable development of hillside areas. The Hillside Development Ordinance includes the following objectives: 1. Provide hillside development standards to maximize the positive impacts of site design, grading, landscape architecture and building architecture, and provide development consistent with the goals and policies of the General Plan. 2. Maintain the essential natural characteristics of the area such as major landforms, vegetation and wildlife communities, hydrologic features, scenic qualities and open space that contribute to a sense of place. 3. Retain the integrity of predominant off -site and on -site views in hillside areas in order to maintain the identity, image and environmental quality of the City. Projects with slopes that average 10% or greater qualify for hillside plan review. As the Proposed Project encompasses slopes of 10% or greater, the Proposed Project is subject to the provisions of this Ordinance. Lyons Avenue/Dockweiler Drive Extension Project 4.1. Aesthetics SCH No. 2013082016 Page 4.1-7 of Santa Clarita 2017 Oak Trees The City of Santa Clarita recognizes indigenous oak trees for their significant historical, aesthetic and environmental value. Native oak trees are protected under City of Santa Clarita Oak Tree Ordinance (Ordinance No. 89-10, passed by the City Council on April 25, 1989) and the City's Oak Tree Preservation and Protection Guidelines (adopted September 11, 1990). As discussed in further detail in Section 4.3 Biological Resources, the City of Santa Clarita requires that all potential impacts to oak trees be preceded by an application to the City that includes a detailed oak tree report and that loss of or damage to protected oaks be mitigated at a minimum 2:1 ratio. Based upon the development and grading footprint of the proposed project as depicted in Figure 2.9, Proposed Site Plan at Lyons Avenue, it has been determined that the 2 oak trees that occur within the project limits would be required to be removed for project construction. The removal of or encroachment to oak trees as a result of project construction would be considered a significant impact under both the City of Santa Clarita and CEQA. Replacement oak trees would be planted in the number necessary to comply with the requirements stipulated in the Oak Tree Permit issued by the City. With approval of the required oak tree permits, and implementation of Mitigation Measure 4.3-7 in Section 4.3, Biological Resources, aesthetic impacts associated with the loss or pruning of any oak tree would be reduced to less than significant levels. Scenic Highways The Project Site is bounded by Lyons Avenue and Railroad Avenue to the west, 13'h Street to north, and the proposed extension of the Dockweiler Drive realignment to the east. None of these roadways are designated as scenic highways. Furthermore, no historic or archaeological resources have been identified within the Project Site (See Section 4.4 Cultural Resources). Beautification Master Plan The Santa Clarita Beautification Master Plan contains Citywide design guidelines as well as specific guidelines tailored to maintain the aesthetic character of the communities of Canyon Country, Newhall, Saugus, and Valencia. The Beautification Master Plan addresses concepts for streetscape design, landscape enhancement, gateways, and monumentation and signage, on both a regional and a community scale. The Master Plan strives to maintain the identity of individual communities while unifying the entire City through design. The Beautification Plan identifies a goal of providing landscaped medians within major arterial roadways in order to provide aesthetic appeal, control vehicle circulation, calm traffic, and provide area for directional and traffic signs. The Beautification Plan identifies Lyons Avenue and Railroad Avenue as targeted areas for landscape median enhancement. Lyons Avenue/Dockweiler Drive Extension Project 4.1. Aesthetics SCH No. 2013082016 Page 4.1-8 of Santa Clarita 2017 4.1.3 ENVIRONMENTAL IMPACTS Thresholds of Significance In accordance with Appendix G to the State CEQA Guidelines, a project would have a significant impact on the environment if it would: (a) Result in a substantial adverse effect on a scenic vista; or (b) Substantially damages scenic resources, including but not limited to, trees, rock outcroppings, and historic buildings within a state scenic highway; or (c) Substantially degrades the existing visual character or quality of the site and its surroundings; or (d) Creates a new source of substantial light or glare which would affect day or nighttime views in the area. Project Impacts Temporary Construction Impacts Existing views and aesthetic character of the Project Site and surrounding area would be adversely impacted by grading, stockpiles of debris and soil, building materials and construction equipment, all of which could occupy the field of view of passing motorists, pedestrians and nearby residents. Portions of the construction site would be visible from the residential properties on Aden Avenue and from passing motorists on Lyons Avenue, Railroad Avenue, Newhall Avenue, Market and Race Streets, and the Arch Street/12th Street/Placerita Canyon intersection. Thus, the existing visual character of the Project Site would be adversely impacted throughout the duration of the construction period. This impact would be considered significant but temporary. Additionally, construction impacts would be reduced to less than significant levels with the implementation of mitigation measure 4.1-1, which would require the contractor to erect screening materials such as fences or other closures to effectively block the line of sight of unsightly stockpiles of construction debris and soil, and construction equipment from neighboring residential properties. Long Term Operational Impacts Upon completion of the Proposed Project the aesthetic character of the Project Site and its immediate surroundings would be permanently altered. The proposed roadway alignment and associated infrastructure would include street widening for Lyons and Railroad Avenue, new at -grade crossing and a secondary east -west arterial roadway connecting Lyons Avenue to the proposed Dockweiler Drive extension, which would connect Dockweiler Drive to a new five -leg intersection or traffic circle at the Arch Street/12th Street/Placerita Canyon intersection. The Proposed Project also includes the closure of the at -grade crossing at the intersection of 13th Street and Railroad Avenue. Lyons Avenue/Dockweiler Drive Extension Project 4.1. Aesthetics SCH No. 2013082016 Page 4.1-9 of Santa Clarita August 2017 Scenic Vistas Roadway Extension at Lyons Avenue and Railroad Avenue Views of the intersection at Lyons Avenue and Railroad Avenue will be altered, as the Proposed Project includes street widening and re -profiling the intersection of Lyons Avenue and Railroad Avenue to allow the construction of a new SCRRA/UP railroad at -grade crossing east of Railroad Avenue and the addition of a new bridge crossing Newhall Creek. As illustrated in the visual simulation renderings depicted in Figure 4.1-4, Old Town Newhall, Railroad Avenue & Lyons Avenue Visual Simulation, and Figure 4.1-5, Race Street/5th Street Terminus Visual Simulation, views of the intersection of Lyons Avenue and Railroad Avenue and the hillside on the southeast portion of the Project Site will be altered by grading for the proposed roadway alignment. Views of the Project Site at the intersection of Railroad Avenue and 13th Street will also be altered as a result of the closure of the at -grade railroad crossing. The Grading Plan and Grading Plan Profile for the roadway extension from Lyons Avenue are shown in Section 2.0, Project Description, Figures 15 and 16, respectively. Additionally, the proposed street widening of Lyons Avenue is depicted in Figure 2-17 in Section 2.0, Project Description. The extension of the proposed roadway (Lyons Avenue) is designated as a Secondary Highway in the City of Santa Clarita's General Plan. This designation is also consistent with the approved Master's University Master Plan, in which Dockweiler Drive was re -designated as a 4-lane Secondary Highway. The roadway extension would be developed in accordance with the City's roadway standards and design guidelines to ensure the graded hillsides, medians, and walkways are landscaped in a manner that maintains the visual aesthetic quality and character of the City's roadway infrastructure. A visual simulation of the proposed Dockweiler Drive Extension just south of the proposed intersection of Arch Street, 12th Street, Placerita Canyon Road and proposed Dockweiler Drive is depicted in Figure 4.1-6. A shown in Figure 4.1-6, the proposed roadway will be a 2-lane facility with a 13-foot parkway on each side. With respect to scenic vistas within the project vicinity, impacts would be reduced to a less than significant impact with implementation of mitigation measure 4.1-2, which would ensure that the roadway median and contoured slopes along the roadway alignment are attractively landscaped and maintained in accordance with landscape plans to the satisfaction of the City Planning Department. Closure of at -grade crossing at 13`h Street and Railroad Avenue Views of the Project Site at 13th Street and Railroad would be improved as the existing traffic signal for a T-intersection operation would be modified so that traffic to and from 13th Street to Railroad Avenue is closed and the at -grade crossing would be removed. New striping, signage and landscaping would be provided along 13th Street. The railroad crossing closure at 13th Street is depicted in Figure 2-10, 13th Street Crossing Closure. No adverse impacts with respect to views of or from the Project Site would occur as a result of the at -grade crossing at 13th Street. Lyons Avenue/Dockweiler Drive Extension Project 4.1.

However, as noted above, the eastern segment of the Dockweiler alignment was previously approved under a separate project entitlement for The Master's University in 2009, which included a Ridgeline Alteration Permit for the eastern segment of this ridgeline.2 As part of the approved entitlements for The Master's College Master Plan in 2008, the extension of Dockweiler Drive east of the Project Site was found to result in the permanent and irreversible grading and re -contouring of the ridgeline. As shown in Figure 4.1-1, the grading limits of the Proposed Project would retain the gradual elevation profile of the base of the ridgeline. Limited views of the altered portion of the ridgeline would be visible from limited points along the public rights -of -way along Market Street and Race Street to the south of the Project Site. (See Figure 4.1-5, Race Street/5th Street terminus Visual Simulation.) However, as noted in the visual simulation, much of the alteration of the existing ridgeline is within the Master's University property, which was approved and authorized under a separate entitlement and evaluated in a prior environmental impact report. As a project design feature the grading plan incorporates landform grading practices to blend the manufactured slopes and required drainage benches into the natural topography to the maximum extent feasible. Plant materials will be utilized to protect slopes from slippage and soil erosion and minimize the visual effects of grading and construction on a hillside area. With incorporation of the project design features to develop and improve a new roadway extension that is consistent with the City's roadway design standards, the Proposed Project would result in a less than significant impact with respect to the loss of an aesthetic natural feature. Visual Character The roadway portion of the Project Site from Lyons Avenue consists of largely undeveloped land that is surrounded by residential, commercial and industrial development. No buildings or development is proposed on the Project Site that would block existing views or substantially degrade the visual character of the existing site. Upon completion, Dockweiler Drive will be improved as a pedestrian, equestrian and bicycle friendly roadway, providing wide sidewalks, Class II bike lanes on each side, and a multi -purpose trail on the east side. Class II bike routes will provide a striped lane for one-way bike travel and will be marked with signs and pavement striping. Multi -purpose trails are to be unpaved and will be available for equestrian, hiking, and mountain bike use. These project features would increase accessibility to scenic natural resources including the Newhall Creek and surrounding ridgelines and mountains. Additionally, the closure of the at -grade crossing at 13th Street would not create an adverse impact with respect to visual character in the project area. Therefore the Proposed Project would have a less than significant impact with respect to public scenic vistas. z Ibid. Lyons Avenue/Dockweiler Drive Extension Project 4.1. Aesthetics SCH No. 2013082016 Page 4.1-14 of Santa Clarita 2017 Roadway Light and Glare Ambient nighttime lighting on the Project Site and in the vicinity is generated by sources that include streetlights, automobile headlights, and indoor/outdoor building lighting. The Project would introduce nighttime lighting to the Project Area, which will include pole -mounted streetlights at intersections, lighted bollards along Dockweiler Drive, flashing safety lighting for the proposed at -grade crossing, and would contribute to additional light and glare from the headlights of vehicles utilizing the roadway. Lighting associated with the Proposed Project uses is not anticipated to substantially impact any surrounding sensitive uses as the street lights would be installed with downward directional fixtures and would not create light trespass onto any adjacent properties. Light emanating from the Proposed Project would be a relatively low-level indirect source of light illuminating the roadway and pedestrian walkways and would not adversely impact other properties in the immediate area. Additionally, the steep terrain and orientation of the southeastern potion of the Project Site at the road extension from Lyons Avenue would shield vehicle headlights, signage lighting and street lights from impacting the residential properties within the Placerita Canyon community to the east and along Market and Race Streets to the west. Overall, the Proposed Project would be expected to slightly increase ambient lighting in the area, but compliance with the design standards and requirements established in the Santa Clarita Municipal Code Section 17.51.050 would mitigate lighting impacts to a less than significant level. 4.1.4 CUMULATIVE IMPACTS The Proposed Project will involve the grading and re -contouring the lower portion of a significant ridgeline for which a Ridgeline Alteration Permit has already been issued for the eastern segment of Dockweiler Drive, that was approved as part of the City's adopted Circulation Element of the General Plan and the approved land use entitlements under The Master's University Master Plan. While the Proposed Project would involve grading and re -contouring of a significant ridgeline, the Proposed Project is consistent with the General Plan and the previously approved Ridgeline Alteration Permit authorized under The Master's University Master Plan (Master Case No. 04-496 and associated Ridgeline Alteration Permit 07-001). Therefore, the Proposed Project would result in a less than significant cumulative aesthetic impact. 4.1.5 MITIGATION MEASURES The following mitigation measures are recommended to ensure that less -than -significant impacts to visual resources would occur: 4.1-1 Construction equipment, debris, and stockpiled equipment shall be visually screened to effectively block the line -of -sight from the ground level of neighboring residential properties. Such barricades or enclosures shall be maintained in appearance throughout the construction period. Graffiti shall be removed immediately upon discovery. Lyons Avenue/Dockweiler Drive Extension Project 4.1. Aesthetics SCH No. 2013082016 Page 4.1-15 of Santa Clarita August 2017 4.1-2 The roadway median and contoured slopes along the roadway alignment shall be attractively landscaped and maintained in accordance with landscape plans to the satisfaction of the City Planning Department. 4.1.6 LEVEL OF SIGNIFICANCE AFTER MITIGATION The Proposed Project would result in temporary adverse impacts to the aesthetic character of the Project Site and its surroundings during the construction period. Such impacts would be reduced to less than significant levels with the implementation of mitigation measure 4.1-1, above, which would require the contractor to erect screening materials such as fences or other closures to effectively block the line of sight of unsightly stockpiles of construction debris and soil, and construction equipment from neighboring residential properties. With mitigation, temporary aesthetic impacts would be reduced to less than significant levels. With the incorporation of mitigation measures, impacts upon aesthetics, including scenic vistas and visual character would be less than significant.

AIR QUALITY 4.2.1 INTRODUCTION This section examines the degree to which the Proposed Project may result in significant environmental impacts with respect to air quality, including short-term construction emissions occurring from activities such as site grading and haul truck trips, and long-term effects related to the changes in the roadway and vehicular circulation system. The analysis contained herein focuses on air pollution from two perspectives: maximum daily emissions and pollutant concentrations. As used in this study, the term "emissions" refers to the quantity of pollutant measured in pounds per day (ppd). The term "concentrations" refers to the amount of pollutant material per volumetric unit of air as measured in parts per million (ppm), parts per billion (ppb), or micrograms per cubic meter (µg/m3). Documents used in the preparation of this section include, but are not limited to, the South Coast Air Quality Management District's (SCAQMD) CEQA Air Quality Handbook (1993), the 2016 Air Quality Management Plan (AQMP), the Air Quality Element of the City of Santa Clarita General Plan, and other applicable federal and state regulations and guidelines. 4.2.2 ENVIRONMENTAL SETTING The Project Site is located within the South Coast Air Basin (Basin). As shown in Figure 4.2-1, SCAQMD Air Basin and SRA Location Map, on page 4.2-2, the Basin includes all of Orange County and the non -desert portions of Los Angeles, San Bernardino, and Riverside Counties. The City of Santa Clarita is located within source receptor area (SRA) 13. The regional climate within the Basin is considered semi -arid and is characterized by warm summers, mild winters, infrequent seasonal rainfall, moderate daytime onshore breezes, and moderate humidity. The air quality within the Basin is primarily influenced by a wide range of emissions sources (e.g., dense population centers, heavy vehicular traffic, and industries) and meteorology. Air Pollutants Air pollutant emissions within the Basin are generated by stationary and mobile sources. Stationary sources can be divided into two major subcategories: point and area sources. Point sources occur at an identified location and are usually associated with manufacturing and industry. Examples of point sources include boilers or combustion equipment that produce electricity or generate heat. Area sources are widely distributed and produce many small emissions. Examples of area sources include residential and commercial water heaters, painting operations, lawn mowers, agricultural fields, landfills, and consumer products such as lighter fluid and hair spray. Mobile sources are emissions from motor vehicles, including tailpipe and evaporative emissions, and are classified as either on -road or off -road. On -road sources may be legally operated on roadways and highways. Off -road sources include aircraft, Lyons Avenue/Dockweiler Drive Extension Project 4.2 Air Quality SCH No. 2013082016 Page 4.2-1 SOUTH COAST AIR QUALITY MANAG 21865 0)pley DrWc, Diamond Ilar.

Air pollutants can also be generated by the natural environment, such as when fine dust particles are pulled off the ground surface and suspended in the air during high winds. Both the federal and state governments have established ambient air quality standards for outdoor concentrations of various pollutants in order to protect public health and welfare. These pollutants are referred to as "criteria air pollutants" as a result of the specific standards, or criteria, that have been adopted for them. The national and state standards have been set at levels considered safe to protect public health, including the health of "sensitive" populations such as asthmatics, children, and the elderly with a margin of safety; and to protect public welfare, including protection against decreased visibility and damage to animals, crops, vegetation, and buildings. The criteria air pollutants that are most relevant to current air quality planning and regulation in the Basin include ozone (03), carbon monoxide (CO), nitrogen dioxide (NOA respirable particulate matter (PM10), fine particulate matter (PM2 5), sulfur dioxide (SOA and lead (Pb). In addition, toxic air contaminants (TACs) are of concern in the Basin. The characteristics of each of these pollutants are briefly described below. • 03 is a highly reactive and unstable gas that is formed when reactive organic gases (ROGs) and nitrogen oxides (NOX), both byproducts of internal combustion engine exhaust, undergo slow photochemical reactions in the presence of sunlight. 03 concentrations are generally highest during the summer months when direct sunlight, light wind, and warm temperature conditions are favorable to the formation of this pollutant. • CO is a colorless, odorless gas produced by the incomplete combustion of carbon -containing fuels, such as gasoline or wood. CO concentrations tend to be the highest on winter mornings, when little to no wind and surface -based inversions trap the pollutant at ground levels. Because CO is emitted directly from internal combustion engines, unlike 03, motor vehicles operating at slow speeds are the primary source of CO in the Basin. The highest ambient CO concentrations are generally found near congested transportation corridors and intersections. • PM o and PM2.5 consist of extremely small, suspended particles or droplets 10 microns and 2.5 microns or smaller in diameter, respectively. Some sources of particulate matter, like pollen and windstorms, are naturally occurring. However, in populated areas, most particulate matter is caused by road dust, diesel soot, combustion products, abrasion of tires and brakes, and construction activities. • NO2 is a nitrogen oxide compound that is produced by the combustion of fossil fuels, such as in internal combustion engines (both gasoline and diesel powered), as well as point sources, especially power plants. Of the seven types of NOX compounds, NO2 is the most abundant in the atmosphere. Because ambient concentrations of NO2 are related to traffic density, commuters in heavy traffic may be exposed to higher concentrations of NO2 than those indicated by regional monitors. Lyons Avenue/Dockweiler Drive Extension Project 4.2. Air Quality SCH No. 2013082016 Page 4.2-3 of Santa Clarita 2017 • SO2 is a colorless, extremely irritating gas or liquid. It enters the atmosphere as a pollutant mainly as a result of burning high sulfur -content fuel oils and coal and from chemical processes occurring at chemical plants and refineries. When S02 oxidizes in the atmosphere, it forms sulfates (SO4). Collectively, these pollutants are referred to as sulfur oxides (SOX). • Ph occurs in the atmosphere as particulate matter. The combustion of leaded gasoline is the primary source of airborne Pb in the Basin. The use of leaded gasoline is no longer permitted for on -road motor vehicles, so the majority of such combustion emissions are associated with off - road vehicles such as racecars. However, because leaded gasoline was emitted in large amounts from vehicles when leaded gasoline was used for on -road motor vehicles, Pb is present in many urban soils and can be re -suspended in the air. Other sources of Pb include the manufacturing and recycling of batteries, paint, ink, ceramics, ammunition, and the use of secondary lead smelters. • TACs refer to a diverse group of air pollutants that are capable of causing chronic (i.e., of long duration) and acute (i.e., severe but of short duration) adverse effects on human health. TACs include both organic and inorganic chemical substances that may be emitted from a variety of common sources including gasoline stations, motor vehicles, dry cleaners, industrial operations, painting operations, and research and teaching facilities. TACs are different than "criteria" pollutants in that ambient air quality standards have not been established for them, largely because there are hundreds of air toxics and their effects on health tend to be felt on a local rather than regional scale. Health Effects of Criteria Pollutants The health effects of the criteria pollutants (i.e., 03, CO, PMI0 and PM25, NO2, S02, and Pb) and TACs are described below.' In addition, a list of the harmful effects of each criteria pollutant is provided in Table 4.2-1, Summary of Health Effects of Criteria Pollutants. Ozone (03) Individuals exercising outdoors, children and people with preexisting lung disease such as asthma and chronic pulmonary lung disease are considered to be the most susceptible sub -groups for ozone effects. Short-term exposures (lasting for a few hours) to ozone at levels typically observed in Southern California 1 The descriptions of the health effects of the criteria pollutants are taken from Appendix C (Health Effects of Ambient Air Pollutants) of the SCAQAID's "Guidance Document for Addressing Air Quality Issues in General Plans and Local Planning" document. Lyons Avenue/Dockweiler Drive Extension Project 4.2.

Elevated ozone levels are also associated with increased school absences. In recent years, a correlation between elevated ambient ozone levels and increases in daily hospital admission rates, as well as mortality, has also been reported. An increased risk for asthma has been found in children who participate in multiple sports and live in high ozone communities. Ozone exposure under exercising conditions is known to increase the severity of the above mentioned observed responses. Animal studies suggest that exposures to a combination of pollutants that include ozone may be more toxic than exposure to ozone alone. Although lung volume and resistance changes observed after a single exposure diminish with repeated exposures, biochemical and cellular changes appear to persist, which can lead to subsequent lung structural changes. Carbon Monoxide (CO) Individuals with a deficient blood supply to the heart are the most susceptible to the adverse effects of CO exposure. The effects observed include earlier onset of chest pain with exercise, and electrocardiograph changes indicative of worsening oxygen supply to the heart. Inhaled CO has no direct toxic effect on the lungs, but exerts its effect on tissues by interfering with oxygen transport by competing with oxygen to combine with hemoglobin present in the blood to form carboxyhemoglobin (COHb). Hence, conditions with an increased demand for oxygen supply can be adversely affected by exposure to CO. Individuals most at risk include patients with diseases involving heart and blood vessels, fetuses, and patients with chronic hypoxemia (oxygen deficiency) as seen in high altitudes. Lyons AvenuelDockweiler Drive Extension Project 4.2. Air Quality SCH No. 2013082016 Page 4.2-5 of Santa Clarita August 2017 Reduction in birth weight and impaired neurobehavioral development has been observed in animals chronically exposed to CO resulting in COHb levels similar to those observed in smokers. Recent studies have found increased risks for adverse birth outcomes with exposure to elevated CO levels. These include pre -term births and heart abnormalities. Additional research is needed to confirm these results. Particulate Matter (PMlo and PM2.5) A consistent correlation between elevated ambient particulate matter (PM10 and PM2 5) levels and an increase in mortality rates, respiratory infections, number and severity of asthma attacks, and the number of hospital admissions has been observed in different parts of the United States and various areas around the world. In recent years, some studies have reported an association between long-term exposure to air pollution dominated by fine particles and increased mortality, reduction in life -span, and lung cancer. Daily fluctuations in fine particulate matter concentration levels have also been related to hospital admissions for acute respiratory conditions in children, school and kindergarten absences, a decrease in respiratory lung volumes in normal children, and increased medication use in children and adults with asthma. Recent studies show that lung function growth in children is reduced with long-term exposure to particulate matter. The elderly, people with pre-existing respiratory or cardiovascular disease, and children appear to be more susceptible to the effects of PM,o and PM2 5• Nitrogen Dioxide (NO2) Population -based studies suggest that an increase in acute respiratory illness, including infections and respiratory symptoms in children (not infants), is associated with long-term exposures to NO2 at levels found in homes with gas stoves, which are higher than ambient levels found in Southern California. Increase in resistance to air flow and airway contraction is observed after short-term exposure to NO2 in healthy individuals. Larger decreases in lung functions are observed in individuals with asthma or chronic obstructive pulmonary disease (e.g., chronic bronchitis, emphysema) than in healthy individuals, indicating a greater susceptibility of these sub -groups. In animals, exposure to levels of NO2 considerably higher than ambient concentrations results in increased susceptibility to infections, possibly due to the observed changes in cells involved in maintaining immune functions. The severity of lung tissue damage associated with high levels of ozone exposure increases when animals are exposed to a combination of 03 and NO2. Sulfur Dioxide (SO2) A few minutes of exposure to low levels of S02 can result in airway constriction in some asthmatics, all of whom are sensitive to its effects. In asthmatics, increase in resistance to air flow, as well as reduction in breathing capacity leading to severe breathing difficulties, are observed after acute exposure to S02. In contrast, healthy individuals do not exhibit similar acute responses even after exposure to higher concentrations of S02. Lyons Avenue/Dockweiler Drive Extension Project 4.2. Air Quality SCH No. 2013082016 Page 4.2-6 of Santa Clarita August 2017 Animal studies suggest that despite S02 being a respiratory irritant, it does not cause substantial lung injury at ambient concentrations. However, very high levels of exposure can cause lung edema (fluid accumulation), lung tissue damage, and sloughing off of cells lining the respiratory tract. Some population -based studies indicate that the mortality and morbidity effects associated with fine particulate matter show a similar association with ambient S02 levels. In these studies, efforts to separate the effects of S02 from those of fine particles have not been successful. It is not clear whether the two pollutants act synergistically or whether one pollutant alone is the predominant factor. Sulfates (SO4) Most of the health effects associated with fine particulate matter and S02 at ambient levels are also associated with SO4. Thus, both mortality and morbidity effects have been observed with an increase in ambient SO4 concentrations. However, efforts to separate the effects of SO4 from the effects of other pollutants generally have not been successful. Clinical studies of asthmatics exposed to sulfuric acid suggest that adolescent asthmatics are possibly a subgroup susceptible to acid aerosol exposure. Animal studies suggest that acidic particles such as sulfuric acid aerosol and ammonium bisulfate are more toxic than non -acidic particles like ammonium sulfate. Whether the effects are attributable to acidity or to particles remains unresolved. Lead Fetuses, infants, and children are more sensitive than others to the adverse effects of lead exposure. Exposure to low levels of lead can adversely affect the development and function of the central nervous system, leading to learning disorders, distractibility, inability to follow simple commands, and lower intelligence levels. In adults, increased lead levels are associated with increased blood pressure. Lead poisoning can cause anemia, lethargy, seizures, and death. It appears that there are no direct effects of lead on the respiratory system. Lead can be stored in the bone from early -age environmental exposure, and elevated blood lead levels can occur due to the breakdown of bone tissue during pregnancy, hyperthyroidism (increased secretion of hormones from the thyroid gland), and osteoporosis (breakdown of bony tissue). Fetuses and breast-fed babies can be exposed to higher levels of lead because of previous environmental lead exposure of their mothers. Toxic Air Contaminants (TACs) TACs are a broad class of compounds known to cause or contribute to cancer or non -cancer health effects such as birth defects, genetic damage, and other adverse health effects. Adverse effects from TACs may be both chronic and acute on human health. Acute health effects are attributable to sudden exposure to high quantities of air toxics. These effects include nausea, skin irritation, respiratory illness, and, in some cases, death. Chronic health effects can result from low -dose, long-term exposure from routine releases of air toxics. The effect of major concern for this type of exposure is cancer, which typically requires a period of 10 to 30 years after exposure to develop. Lyons Avenue/Dockweiler Drive Extension Project 4.2. Air Quality SCH No. 2013082016 Page 4.2-7 of Santa Clarita August 2017 TACs are found in ambient air, especially in urban areas, and are caused by industry, agriculture, fuel combustion, and commercial operations (e.g., dry cleaners). TACs are typically found in low concentrations, even near their source (e.g., benzene near a freeway). Because chronic exposure can result in adverse health effects, TACs are regulated at the regional, state, and federal level. Diesel exhaust, which is comprised of a complex mixture of gases, vapors, and fine particles, is the predominant TAC in urban air and is estimated to represent about two-thirds of the cancer risk from TACs (based on the statewide average). This complexity makes the evaluation of health effects of diesel exhaust a complex scientific issue. Some of the chemicals in diesel exhaust, such as benzene and formaldehyde, have been previously identified by the CARB as TACs, and are listed as carcinogens either under California's Proposition 65 or under the federal Hazardous Air Pollutants programs. The United States Environmental Protection Agency (U.S. EPA) has adopted Ultra Low Sulfur Diesel (ULSD) fuel standards to reduce diesel particulate matter. As of December 10, 2010, only ULSD fuel is available for highway use nationwide. In California, which was an early adopter of ULSD fuel and engine technologies, 100 percent of the diesel fuel sold — downstream from refineries, up to and including fuel terminals that store diesel fuel — has been ULSD fuel since July 15, 2006. Multiple Air Toxics Exposure Study In May 2015, the SCAQMD published the MATES IV, Multiple Air Toxics Exposure Study (the "MATES IV Study"), which provides a comprehensive regional air toxics study for the entire South Coast Air Basin. The MATES IV Study is an update to previous air toxics studies in the Basin and is part of the SCAQMD Governing Board Environmental Justice Initiative. It consists of a one-year monitoring study, an updated air toxic emissions inventory, as well as updates to monitored and modeled exposures and risk estimated from air toxics. The objective of the Study is to update the characterization of ambient air toxic concentrations and potential exposures to air toxics in the Basin. The MATES IV Study concluded that average risks throughout the Basin are dramatically reduced from previous studies. Generally, the risk from air toxics is lower near the coastline and increases inland, with higher risks concentrated near large diesel sources (e.g., freeways, airports, and ports). The average carcinogenic risk Basin -wide is about 420 cases per million over a 70-year duration. This compares to about 1,400 per million in the MATES II Study, and about 1,200 per million in the MATES III Study. For comparison purposes, Table 4.2-2, Modeled Air Toxics Risk Comparisons Using the CAMx Model, below, shows the estimated population weighted risk across the Basin for the MATES III and MATES IV periods. The population weighted risk was about 57% lower compared to the MATES III period (2005).2 The MATES -IV interactive map, published on the SCAQMD's web site, provides model -calculated cancer risks over the Basin on a 2 km by 2 km grid overlay. Based on this geo-referenced database, TAC- related cancer risk in the Newhall area is estimated at approximately 334 per million, which is below the average Basin -wide estimate of 420 per million. 2 SCAQMD, Final Draft Report, Multiple Air Toxics Exposure Study IV Model Estimated Carcinogenic Risk, at page ES-3.

Regulatory Setting Air quality within the Basin is addressed through the efforts of various federal, state, regional, and local government agencies. These agencies work jointly, as well as individually, to improve air quality through legislation, regulations, planning, policy -making, education. and a variety of programs. At the federal level air quality is governed by the Federal Clean Air Act (CAA). The CAA is administered by the U.S. EPA. In California, air quality is also governed by more stringent regulations under the California Clean Air Act (CCAA). The CCAA is administered by the CARB at the state level and by the Air Quality Management Districts at the regional and local levels. The agencies responsible for improving the air quality within the Basin are discussed below. Federal Standards The U.S. Environmental Protection Agency (U.S. EPA) The U.S. EPA is responsible for setting and enforcing the federal ambient air quality standards for atmospheric pollutants. It regulates emission sources that are under the exclusive authority of the federal government, such as aircraft, ships, and certain locomotives. The U.S. EPA also has jurisdiction over emissions sources outside state waters (outer continental shelf) and establishes various emissions standards for vehicles sold in states other than California. As part of its enforcement responsibilities, the U.S. EPA requires each state with nonattainment areas to prepare and submit a State Implementation Plan (SIP). The SIP is a plan for each state which identifies how that state will attain and/or maintain the primary and secondary National Ambient Air Quality Standards (NAAQS) set forth in section 109 of the CAA. These plans are developed through a public process, formally adopted by the state. and submitted by the Governor's designee to the U.S. EPA. The CAA requires the U.S. EPA to review each plan and any plan revisions and to approve the plan or plan revisions if consistent with the CAA. State Standards California Air Resources Board (CARB) The GARB, a part of the California Environmental Protection Agency, is responsible for the coordination and administration of both federal and state air pollution control programs within California. In this Lyons Avenue/Dockweiler Drive Extension Project 4.2. Air Quality SCH No. 2013082016 Page 4.2-9 of Santa Clarita August 2017 capacity, the CARB conducts research, sets California Ambient Air Quality Standards, compiles emission inventories, develops suggested control measures, and provides oversight of local programs. The CARB establishes emissions standards for motor vehicles sold in California, consumer products (such as hair spray, aerosol paints, and lighter fluid), and various types of commercial equipment. It also sets fuel specifications to further reduce vehicular emissions. In some cases, the state standards are more restrictive than the federal standards established under the CAA. Table, 4.2-3, Ambient Air Quality Standards, above, identifies the applicable state ambient air quality standards alongside the federal standards for comparison. Measurements of ambient concentrations of the criteria pollutants are used by the U.S. EPA and the CARB to assess and classify the air quality of each air basin, county, or, in some cases, a specific urbanized area. The classification is determined by comparing actual monitoring data with national and state standards. If a pollutant concentration in an area is lower than the standard, the area is classified as being in "attainment." If the pollutant exceeds the standard, the area is classified as a "non -attainment" area. If there is not enough data available to determine whether the standard is exceeded in an area, the area is designated "unclassified." Off -road diesel vehicles, which include construction equipment, are also regulated by the CARB for both in -use (existing) and new engines. Four sets of standards implemented by the CARB for new off -road diesel engines, known as Tiers. Tier 1 standards began in 1996. Tiers 2 and 3 were adopted in 2000 and were more stringent than the Tier 1 standards. Tier 2 and Tier 3 standards were completely phased in by 2006 and 2008, respectively. Tier 4 standards became effective in 2011. Tier 4 emission standards will reduce particulate matter and NOx emissions of late model cars to 90 percent below current levels. Since off -road vehicles that are used in construction and other related industries can last 30 years or longer, most of those that are in service today are still part of an older fleet that do not have emission controls. On July 26, 2007, the CARB approved a regulation, the "In -Use Off -Road Diesel Fueled Fleets Regulation" to reduce emissions from existing (in -use) off -road diesel vehicles that are used in construction and other industries. This regulation became effective on June 15, 2008, and sets an anti - idling limit of five minutes for all off -road vehicles 25 horsepower and up. It also establishes emission rates targets for the off -road vehicles that decline over time to accelerate turnover to newer, cleaner engines and require exhaust retrofits to meet these targets. Revised in October 2016, the regulation enforced off -road restrictions on fleets adding vehicles with older tier engines, and started enforcing beginning July 1, 2014. By each annual compliance deadline, a fleet must demonstrate that it has either met the fleet average target for that year, or has completed the Best Available Control Technology requirements (BACT). Large fleets have compliance deadlines each year from 2014 through 2023, medium fleets each year from 2017 through 2023, and small fleets each year from 2019 through 2028.

Regional Standards Southern California Association of Governments (SLAG) The Southern California Association of Governments (SCAG) is a council of governments for Imperial. Los Angeles, Orange, Riverside, San Bernardino, and Ventura Counties. SCAG is a regional planning agency and forum for regional issues relating to transportation, the economy and community development, and the environment. Although SCAG is not an air quality management agency, it is responsible for developing transportation, land use, and energy conservation measures that affect air quality. SCAG's 2008 Regional Comprehensive Plan (2008 RCP) provides growth forecasts that are used in the development of air quality -related land use and transportation control strategies by the SCAQMD. The 2008 RCP is a framework for decision -making for local governments, assisting them in meeting federal and state mandates for growth management, mobility. and environmental standards, while maintaining consistency with regional goals regarding growth and changes through the year 2035, and beyond. The 2008 RCP is Lyons Avenue/Dockweiler Dfive Extension Project 4.2. Air Quality SCH No. 2013082016 Page 4.2-11 of Santa Clarita August 2017 laid out much like a General Plan and organizes recommended policies into nine chapters; land use, open space and habitat, water, energy, air quality, solid waste, transportation, security and emergency preparedness, economy and education. The 2008 RCP is closely tied to the 2016 Regional Transportation Plan/Sustainable Communities Strategy (RTP/SCS), which is summarized below. The 2016-2040 RTP/SCS, adopted on April 7, 2016, is the culmination of a multi -year effort involving stakeholders from across the SCAG Region. The 2016-2040 RTP/SCS provides a blueprint for improving quality of life for residents by providing more choices for where they will live, work, and play, and how they will move around. The 2016-2040 RTP/SCS encourages strategic transportation investments that add appropriate capacity and improve critical road conditions in the region. Improved placemaking and strategic transportation investments would help to improve air quality. Based on the regional growth projections in the 2016-2040 RTP/SCS, in 2012, the City of Santa Clarita had an estimated population of approximately 202,000 persons, approximately 67,300 residences, and 73,500 jobs. By the year 2040, SCAG forecasts the City of Santa Clarita will increase to 262,200 persons (an approximate 30% increase from the year 2012), approximately 90,300 residences (an approximate 34% increase from the year 2012), and approximately 95,900 jobs (an approximate 30% increase since year 2012) citywide. These growth projections form the basis for the strategies identified in the SCAQMD's 2016 Air Quality Management Plan (AQMP). South Coast Air Quality Management District (SCAQMD) The SCAQMD is the agency principally responsible for comprehensive air pollution control in the Basin. To that end, the SCAQMD, a regional agency, works directly with SCAG, county transportation commissions and local governments, and cooperates actively with state and federal government agencies. The SCAQMD develops air quality related rules and regulations, establishes permitting requirements, inspects emissions sources, and provides regulatory enforcement through such measures as educational programs or fines, when necessary. The SCAQMD is directly responsible for reducing emissions from stationary (area and point), mobile, and indirect sources to meet federal and state ambient air quality standards. SCAQMD has responded to this requirement by preparing a series of AQMPs. The most recent AQMP was adopted by the Governing Board of the South Coast Air Quality Management District (SCAQMD) on March 3, 2017 ("2016 AQMP"). The 2016 AQMP represents a thorough analysis of existing and potential regulatory control options, includes available, proven, and cost-effective strategies, and seeks to achieve multiple goals in partnership with other entities promoting reductions in greenhouse gasses and toxic risk, as well as efficiencies in energy use, transportation, and goods movement. The 2016 AQMP recognizes the critical importance of working with other agencies to develop funding and incentives that encourage the accelerated transition to cleaner vehicles, and the modernization of buildings and industrial facilities to cleaner technologies in a manner that benefits not only air quality, but also local businesses and the regional economy. In addition, the Southern California Association of Governments (SCAG) recently approved their 2016 RTP/SCS that include transportation programs, measures, and strategies generally designed to reduce vehicle miles traveled (VMT), which are contained within baseline emissions inventory in the 2016 AQMP. The transportation strategy and transportation control measures (TCMs), Lyons Avenue/Dockweiler Drive Extension Project 4.2. Air Quality SCH No. 2013082016 Page 4.2-12 of Santa Clarita August 2017 included as part of the 2016 AQMP and SIP for the South Coast Air Basin, are based on SCAG's 2016 RTP/SCS and Federal Transportation Improvement Program (FTIP). For purposes of assessing a project's consistency with the AQMP, projects that are consistent with the growth forecast projections of employment and population forecasts identified in the RTP/SCS are considered consistent with the AQMP, since the growth projections contained in the RTP/SCS form the basis of the land use and transportation control portions of the AQMP. The future air quality levels projected in the 2016 AQMP are based on several assumptions. For example, the SCAQMD assumes that general new development within the Basin will occur in accordance with population growth and transportation projections identified by SCAG's 2016-2040 RTP/SCS. The 2016 AQMP also assumes that general development projects will include feasible strategies (i.e., mitigation measures) to reduce emissions generated during construction and operation in accordance with SCAQMD and local jurisdiction regulations, which are designed to address air quality impacts and pollution control measures. The 2016 AQMP incorporates new scientific data, primarily in the form of updated emissions inventories, ambient measurements, new meteorological episodes, and new air quality modeling. General development projects would be affected in the form of any applicable rules and regulations — if any — that are adopted as a result of the 2016 AQMP. While economic growth for the region is desirable, it presents a challenge to air quality improvement efforts since the projected growth could offset the impressive progress made in reducing VOC, NOx, and PM2.5 emissions through adopted regulations. Meeting the U.S. EPA's current and more -stringent future air quality standards will require the continuation of emission reduction efforts from all levels of government. In addition to the AQMP, the SCAQMD has prepared the CEQA Air Quality Handbook (1993) to assist lead agencies, as well as consultants, project proponents, and other interested parties, in evaluating potential air quality impacts of projects and plans proposed in the Basin. The AQMD is in the process of developing an `Air Quality Analysis Guidance Handbook" to replace the CEQA Air Quality Handbook approved by the AQMD Governing Board in 1993. Among the SCAQMD rules applicable to the Proposed Project are Rule 403 (Fugitive Dust), Rule 1108 (Cutback Asphalt) and Rule 1108.1 (Emulsified Asphalt), and Rule 1120 (Asphalt Pavement Heaters). Rule 403 requires the use of stringent best available control measures to minimize PM,o emissions during grading and construction activities. Rules 1108 and 1108.1 would limit the VOC content of asphalt materials. Rule 1120 would place restrictions on the use of asphalt pavement surface heaters and asphalt heater-remixers for the purpose of maintaining, reconditioning, reconstructing, or removing asphalt pavement. Additional details regarding these rules are presented below. • Rule 403 (Fugitive Dust): This rule requires fugitive dust sources to implement Best Available Control Measures for all sources and all forms of visible particulate matter are prohibited from crossing any property line. SCAQMD Rule 403 is intended to reduce PM1O emissions from any transportation, handling, construction, or storage activity that has the potential to generate fugitive dust (see also Rule 1186). Lyons Avenue/Dockweiler Drive Extension Project 4.2. Air Quality SCH No. 2013082016 Page 4.2-13 of Santa Clarita 2017 • Rule 1108 (Cutback Asphalt): This rule restricts the use of any cutback asphalt containing more than 0.5 percent by volume of organic compounds which evaporate at 260 °C (500 °F) or lower. Rule 1108 is intended to reduce VOC emissions from the application of asphalt. • Rule 1108.1 (Emulsified Asphalt): This rule restricts the use of any emulsified asphalt containing organic compounds which evaporate at 260 °C (500 °F) or lower. Rule 1108.1 is intended to reduce VOC emissions from the application of asphalt. • Rule 1120 (Asphalt Pavement Heaters): This rule restricts the use of asphalt pavement surface heaters or asphalt heater remixer for the purpose of maintaining, reconditioning, reconstructing or removing asphalt pavement. This rule is intended to reduce smoke and emissions which contain sulfur, VOCs, and other TACs. Local Regulations Local governments, such as the City of Santa Clarita, share the responsibility to implement or facilitate some of the control measures of the AQMP. These governments have the authority to reduce air pollution through local policies and land use decision -making authority. Specifically, local governments are responsible for the mitigation of emissions resulting from land use decisions and for the implementation of transportation control measures as outlined in the AQMP. The AQMP assigns local governments certain responsibilities to assist the SoCAB in meeting air quality goals and policies. In general, the first step towards assigning a local government's responsibility is accomplished by identifying the air quality goals, policies, and implementation measures in its general plan. The City of Santa Clarita has done this through its proposed General Plan Conservation and Open Space Element. Through capital improvement programs, local governments can fund infrastructure that contributes to improved air quality, by requiring such improvements as bus turnouts, energy -efficient streetlights and synchronized traffic signals .3 In accordance with the CEQA requirements and the CEQA review process, local governments assess air quality impacts, require mitigation of potential air quality impacts by conditioning discretionary permits, and monitor and enforce implementation of such mitigation. Ambient Air Quality Conditions Existing Regional Air Quality Ambient air quality is determined primarily by the type and amount of pollutants emitted into the atmosphere, as well as the size, topography, and meteorological conditions of a geographic area. The Air Basin has low mixing heights and light winds, which help to accumulate air pollutants. The most current average daily emissions inventory for the entire Basin and the Los Angeles County portion of the Basin is summarized in Table 4.2-4, 2012 Estimated Annual Average Emissions.4 As shown, exhaust emissions from mobile sources generate the majority of ROG, CO, NOX, and SOX emissions in the Basin and the Los Angeles County portion of the Basin. Area -wide sources generate the most airborne particulates (i.e., PM10 and PM2 5) in both the Basin and Los Angeles County. South Coast Air Quality Management District, CEQA Air Quality Handbook, (1993) 2-2. 4 The estimated regional annual average emissions for 2013 through 2014 have not yet been published.

Existing Local Air Quality The SCAQMD divides the Basin into 38 source receptor areas (SRAs) in which 38 monitoring stations track the various concentrations of air pollutants in the region. As shown in Figure 4.1.1, SCAQMD Air Basin and SRA Location Map, the Project Site is located within SRA 13, which covers the Santa Clarita Valley. SCAQMD air quality monitoring Station No. 090 is located at 22224 Placerita Canyon road and is located within the boundaries of the Project Site's northern alignment of Dockweiler Drive extending to Arch Street. This station currently monitors emission levels of CO, NO2, 03, PMIO, PMZ 5, and VOC, Table 4.2-5.

Localized Carbon Monoxide Emissions The SCAQMD recommends the use of CALINE4, a dispersion model for predicting CO concentrations, as the preferred method of estimating localized pollutant concentrations at sensitive receptors near congested roadways and intersections. For this analysis, localized CO concentrations were calculated based on a simplified CALINE4 screening procedure developed by the Bay Area Air Quality Management District and widely accepted by the SCAQMD for CEQA based analyses. The simplified procedure is intended as a screening analysis, which identifies a potential CO hotspot. This methodology assumes worst -case conditions and provides a screening of maximum. worst -case CO concentrations. The emission factors used in the analysis are from the latest CAIZB Emission Factors (EMFAC) model, ENTAC2011. Lyons Avenue/Dockweiler Drive Extension Project 4.2. Air Quality SCH No. 2013082016 Page 4.2-16 City of Santa Clarita August 2017 SCAQMD recommends an evaluation of potential localized CO impacts when volume to capacity (V/C) ratios are increased by two percent or more at intersections with a level of service (LOS) of C or worse, or when LOS changes from an A. B, or C to a D or worse. As shown in the Project Traffic Study, this criteria was met at 10 intersections under the Future With Project scenario, and 6 intersections under the Existing With Project scenario. Thus, existing CO concentrations have been estimated for all 10 corresponding intersections. The results of the existing CO concentration calculations are presented in Table 4.2-6. Existing (2015) Localized Carbon Monoxide Concentrations, for representative receptors located distances of 25 and 50 feet from each roadway. These sensitive receptor locations were selected because they represent locations where a person may be living or working for one to eight or more hours at a time. The national 1-hour CO ambient air quality standard is 35.0 ppm, and the State 1-hour CO ambient air quality standard is 20.0 ppm. The 8-hour national and State standards for localized CO concentrations are 9.0 ppm. As shown in Table 4.2-6, existing CO concentration levels at the study intersections currently do not exceed the national and State 1-hour and 8-hour CO standards.

Sensitive Receptors Local governments have a responsibility for determining land use compatibility in the case of sensitive receptors. For the purposes of a CEQA analysis, the SCAQMD considers a sensitive receptor to be a receptor such as residence, hospital, convalescent facility were it is possible that an individual could remain for 24 hours.6 The SCAQMD has also defined the term sensitive receptor to include private homes, condominiums, apartments, and living quarters. schools, preschools. daycare centers, and health facilities such as hospitals or retirement and musing homes, long term care hospitals, hospices, prisons, and dormitories or similar live-in housing.'

Consistency with the Applicable AQMP Violation of Standards or Substantial Contribution to Air Quality Violations As the agency principally responsible for comprehensive air pollution control in the Basin, the SCAQMD recommends that projects should be evaluated in terms of air pollution control thresholds established by the SCAQMD and published in the CEQA Air Quality Handbook. These thresholds were developed by the SCAQMD to provide quantifiable levels to which projects can be compared. The most current significance thresholds are shown in Table 4.2-7, SCAQMD Air Quality Significance Thresholds. The SCAQMD has adopted criteria for consistency with regional plans and the regional AQMP in its CEQA Air Quality Handbook. Specifically, the indicators of consistency are: 1) whether the project would increase the frequency or severity of existing air quality violations or cause or contribute to new air quality violations; and 2) whether the project would exceed the assumptions utilized in preparing the AQMP. According to the guidance set forth in SCAQMD CEQA Air Quality Handbook, the consistency criteria for the first criterion pertains to pollutant concentrations rather than to total regional emissions. As such, an analysis of the Proposed Project's pollutant emissions relative to localized pollutant concentrations is used as the basis for evaluating Project consistency with the first criterion. With regard to the second criterion, projects that are consistent with the regional population, housing, and employment forecasts identified by SCAG are considered to be consistent with the AQMP growth projections, since the forecast assumptions by SCAG forms the basis of the land use and transportation control portions of the AQMP. The Proposed Project does not include the development of any residential uses. Furthermore, because the Proposed Project consists of building out a roadway segment that was previously adopted as part of the City's Circulation Element of the General Plan, the Proposed Project would not be considered growth -inducing. Therefore, this criterion is not applicable to the Proposed Project. Lyons Avenue/Dockweiler Drive Extension Project 4.2.

Air Quality SCH No. 2013082016 Page 4.2-21 of Santa Clarita 2017 Cumulatively Considerable Net Increase of Criteria Pollutants The SCAQMD's CEQA Air Quality Handbook identifies several methods to determine the cumulative significance of land use projects (i.e., whether the contribution of a project is cumulatively considerable). However, the SCAQMD no longer recommends the use of these methodologies. Instead, the SCAQMD recommends that any construction -related emissions and operational emissions from individual development projects that exceed the project -specific mass daily emissions thresholds identified above also be considered cumulatively considerable.9 The SCAQMD neither recommends quantified analyses of the emissions generated by a set of cumulative development projects nor provides thresholds of significance to be used to assess the impacts associated with these emissions. CO Hotspot Concentrations The SCAQMD recommends that impacts to sensitive receptors be considered significant when a project generates localized pollutant concentrations of NO2, CO, PM10, or PM25 at sensitive receptors near a Project Site that exceed the localized pollutant concentration thresholds or when a project's traffic causes CO concentrations at sensitive receptors located near congested intersections to exceed the national or state ambient air quality standards. The roadway CO thresholds would also apply to the contribution of emissions associated with cumulative development. Localized Significance Thresholds To assess localized impacts, SCAQMD developed mass -based localized significance thresholds (LSTs) that determine the amount of pounds of emissions per day that can be generated by a project that would cause or contribute to adverse localized air quality impacts. These localized thresholds, which are found in the mass rate look -up tables in the "Final Localized Significance Threshold Methodology" guidance document prepared by the SCAQMD,10 apply to projects that are less than or equal to five acres in size and are only applicable to the following criteria pollutants: NOX, CO, PM10, and PM2 5. LSTs represent the maximum emissions from a project that are not expected to cause or contribute to an exceedance of the most stringent applicable federal or state ambient air quality standards, and are developed based on the ambient concentrations of that pollutant for each SRA. In terms of NOX emissions, the two principal species of this pollutant are nitric oxide (NO) and NO2, with the vast majority (95 percent) of the NOX emissions being comprised of NO. However, because adverse health effects are associated with NO2, the analysis of localized air quality impacts associated with NOX emissions is focused on NO2 levels. NO is converted to NO2 by several processes, the two most important of which are (1) the reaction of NO with ozone, and (2) the photochemical reaction of NO with hydrocarbons. When modeling NO2 emissions from combustion sources, the SCAQMD assumes that the conversion of NO to NO2 is complete at a distance of 5,000 meters from the source. For PM10 LSTs, the thresholds were derived based on 9 White Paper on Regulatory Options for Addressing Cumulative Impacts from Air Pollution Emissions, SCAQMD Board Meeting, September 5, 2003, Agenda No. 29, Appendix D, p. D-3. 10 SCAQMD, Final Localized Significance Threshold Methodology, June 2003, Revised July 2008. Lyons Avenue/Dockweiler Drive Extension Project 4.2. Air Quality SCH No. 2013082016 Page 4.2-22 of Santa Clarita August 2017 requirements in SCAQMD Rule 403 — Fugitive Dust. For PM2 5 LSTs, the thresholds were derived based on a general ratio of PM2 5 to PM,o for both fugitive dust and combustion emissions. Exposure to Objectionable Odors A significant impact may occur if objectionable odors occur that would adversely impact sensitive receptors. Odors are typically associated with industrial projects involving the use of chemicals, solvents, petroleum products, and other strong -smelling elements used in manufacturing processes, as well as sewage treatment facilities and landfills. Project Impacts Construction Construction of the Proposed Project would occur over an approximate 12-month timeframe and would involve clearing, grading, excavation, trenching, and asphalt paving. Construction would require 4,990 cubic yards (cy) of cut, 2,760 cy of fill, and 2,230 cy of soil export associated with grading and excavation. During construction, on -site stationary sources, heavy-duty construction vehicles, construction worker vehicles, and energy use would generate emissions. Additionally, grading, excavation, and other construction activities on the Project Site would generate fugitive dust emissions. Construction activities and their associated air quality impacts would be short-term in nature and limited only to the period when construction activity is actively taking place on the Project Site. The Project Site is approximately 5 acres in size and consists of natural land area. For purposes of this analysis it is assumed that a maximum of approximately 2 acres would be disturbed on a daily basis during the development of the Proposed Project. Clearing and grubbing of the area is expected to begin in December of 2019 and last through the end of 2020. Construction emission calculations were obtained from the Roadway Construction Emissions Model, Version 7.1.5.1, which was developed by the Sacramento Metropolitan Air Quality Management District (SMAQMD). The Roadway Construction Emissions Model is used to assess the emissions from linear construction projects, such as roadways and incorporates factors from California Air Resource Board's (CARB's) EMFAC2011 on -road vehicle emissions model and CARB's OFFROAD2011 off -road vehicle emissions model. Both EMFAC2011 and OFFROAD2011 contain the most up-to-date emission factors for on -road and off -road vehicles. Emission calculations and air quality modeling data is provided in Appendix C, Air Quality Worksheets. The emission calculations assume the use of standard construction practices, such as compliance with SCAQMD Rule 403 (Fugitive Dust), to minimize the generation of fugitive dust. Compliance with Rule 403 is mandatory for all construction projects. In the Road Construction Emissions Model, Version 7.1.5.1, the emission calculations take into account compliance with Rule 403 by incorporating watering of the site during construction. Table 4.2-8, Estimated Construction Emissions, identifies the maximum daily emissions for each pollutant during each phase of project construction. As shown in Table 4.2-8, the Proposed Project's construction emissions would be below the SCAQMD's significance thresholds for all criteria pollutants. Therefore, the Proposed Project's regional construction air quality emissions would be less than significant. Lyons Avenue/Dockweiler Drive Extension Project 4.2.

Calculation streets areprovided in Appendix C to this EIR AQMP Consisten(y As noted above, the Proposed Project would not exceed the AQMD's significance thresholds for regional construction emissions and thus would not increase the frequency or severity of existing air quality violations or cause or contribute to new air quality violations within the Basin. The 2016 AQMP was prepared to accommodate growth, to reduce the high levels of pollutants within the area under the jurisdiction of SCAQMD, to return clean air to the region, and to tminitni a the impact on the economy. Projects that are considered consistent with the AQMP would not interfere with attainment because this growth is included in the projections utilized in the formulation of the AQMP. Therefore, projects, uses, and activities that are consistent with the applicable assumptions used in the development of the AQMP would not jeopardize attainment of the air quality levels identified in the AQMP, even if they exceed the SCAQMD's recommended daily emissions thresholds. The Proposed Project would complete a segment of an approved Secondary Highway of the Circulation Element of the General Plan which would improve traffic conditions associated with the future buildout of the Santa Clarita Valley. Reductions in congestion and vehicle miles travelled (VMT) will also occur from the addition of bicycle and pedestrian facilities. Class H bicycle lanes and 8 foot sidewalks will be constructed on both sides of the road resulting in reduced trip lengths from the current circuitous route and provide direct access from the residential and Master's University area to the Jan Heidt Newhall Metrolink Station and Old Town Newhall. These project features would also serve to provide alternative modes of transportation other than motor vehicles and would be consistent with the goals and objectives of the AQMP to reduce vehicle emissions throughout the Basin. Consistency with the City of Santa Clarity Air Quality Element Local jurisdictions, including the City, have the authority and responsibility to reduce air pollution through its police power and decision. -snaking authority. Specifically, the City is responsible for the assessment and mitigation of air emissions resulting from its land use decisions. Lyons Avenue/Dockweiler Drive Extension Project 4.2. Air Quality SCH No. 2013082016 Page 4.2-24 City of Santa Clarita August 2017 The City's Air Quality Element describes the local and regional setting, conditions and environment, which affect the air quality in the Valley. A detailed analysis of the consistency of the Proposed Project with relevant policies in the City's Air Quality Element is presented in Table 4.2-9, Project Consistency with Applicable Policies of the City's General Plan Air Quality Element. As shown in Table 4.2-9, the Project would be consistent with the applicable goals, objectives, and policies set forth in the City's Air Quality Element." Therefore, impacts related to consistency with the applicable air quality policies in the General Plan would be less than significant.

Policy- 5.2: Promote synchronization of traffic Consistent: As previously discussed, the Proposed lights to reduce emissions from delays. Project's mitigation measures listed in Section 4.9 Transportation and Traffic would modify circulation and traffic signals in the Project area in order to reduce delays at intersections.

The Proposed Project would also implement mitigation measure 4.2-4 which requires the use of low-VOC materials during the construction phase. Among the SCAQMD rules applicable to the Proposed Project are Rule 403 (Fugitive Dust), Rule 1108 (Cutback Asphalt) and Rule 1108.1 (Emulsified Asphalt), and Rule 1120 (Asphalt Pavement Heaters). Rule 403 requires the use of stringent best available control measures to minimize PMIo emissions during grading and construction activities. Rules 1108 and 1108.1 would limit the VOC content of asphalt materials. Rule 1120 would place restrictions on the use of asphalt pavement surface heaters and asphalt heater-remixers for the purpose of maintaining, reconditioning, reconstructing, or removing asphalt pavement. Therefore, with implementation of the mitigation measures listed below, the Proposed Project would be consistent with this policy. Consistent. Construction activities associated with the Project would be required to comply with SCAQMD Rule 403—Fugitive Dust, which requires appropriate dust control measures to be implemented during each phase of development. (See Mitigation Measure 4.2-1). Consequently, particulate emissions at the Project Site during construction of the Proposed Project would be minimized. The Proposed Project would not utilize any unpaved roads for access. During the earthwork phases of construction, the Project Site would be watered to suppress dust emissions as required through SCAQMD Rule 403. Additionally, as stated above, Rules 1108 and 1108.1 would limit the VOC content of asphalt materials. Rule 1120 would place restrictions on the use of asphalt pavement surface heaters and asphalt heater-remixers for the purpose of maintaining, reconditioning, reconstructing, or removing asphalt pavement. Therefore, the Proposed Proiect would be consistent with this nolicv. Souree: Policies applicable to the Project were derived from the City's General Plan Air Quality Element, Amended May 23, 2000; Project consistency analysis by Parker Environmental Consultants, 2016. Localized Construction Emissions The Proposed Project would result in significant localized air emissions in close proximity to residential land uses within 100 meters of the Project Site on a temporary and intermittent basis during construction. The daily on -site construction emissions generated by the Project were analyzed against the SCAQMD's localized significance thresholds for the specified criteria pollutants to determine whether the Proposed Project's on -site construction emissions would cause or contribute to adverse localized air quality resulting in impacts to sensitive receptors. For purposes of estimating on -site construction emissions, Roadway Construction Emissions Model, Version 7.1.5.1, was used to estimate only the on -site emissions (e.g., Lyons Avenue/Dockweiler Drive Extension Project 4.2. Air Quality SCH No. 2013082016 Page 4.2-26 of Santa Clarita August 2017 excluding factors associated with off -site hauling and worker commuting emissions). Under this scenario, the localized air quality impacts were then compared to the SCAQMD's localized significance thresholds screening criteria for a 2-acre site, as it is anticipated that no more than 2 acres would be disturbed at the same time. The specific thresholds of significance for the sensitive receptors identified in Figure 4.2-2, Air Quality Sensitive Receptor Map, were derived from the Localized Significance Threshold's Appendix C mass look up rates, based on their location relative to the Proposed Project's grading footprint. As shown in Table 4.2-10, localized NOx and CO emissions would be below the significance thresholds at all sensitive receptor locations. However, localized thresholds would be exceeded for PMI0 and PM25 emissions at two locations: (1) the single family residential land uses located immediately north of the Project Site on Aden Avenue (within a proximity of 100 meters of the edge of the Project Site) and (2) the residential land uses within 100 meters south of the Project Site in the vicinity of Market Street and Race Street. Localized emissions would be below the stated thresholds for any land use located further than 100 meters from the Project Site. Therefore, localized air quality impacts resulting from construction activities would be considered significant. Operational Emissions Although the Proposed Project would not directly generate any new vehicle trips, the Proposed Project would result in changes to the traffic circulation in the vicinity and would alter the average daily traffic volumes and peak hour traffic volumes at local intersections. As such, a CO hotspot analysis was conducted for selected study intersections meeting the evaluation criteria discussed above utilizing the simplified CALINE4 screening model developed by the Bay Area Air Quality Management District (BAAQMD). The simplified model is intended as a screening analysis that identifies a potential CO hotspot. If a hotspot is identified, the complete CALINE4 model is then utilized to determine precisely the CO concentrations predicted at the intersections in question. This methodology assumes worst -case conditions (i.e., wind direction is parallel to the primary roadway and 90 degrees to the secondary road, wind speed of less than 1 meter per second and extreme atmospheric stability) and provides a screening of maximum, worst -case, CO concentrations. This model is utilized to predict existing and future CO concentrations 0 feet from the intersections in the study area based on projected traffic volumes from these intersections contained in the project traffic study. Interim year 2019 with -project conditions CO concentrations were calculated for peak hour traffic volumes for those intersections that are anticipated to operate at LOS D or worse, based on the traffic analysis for the project (See Section 4.9, Transportation and Traffic). Background (existing) ambient CO concentrations were also factored into the analysis. The results of these CO Hotspot concentration calculations are presented in Table 4.2-11, Existing Conditions Plus Project (2019) Carbon Monoxide Concentrations. As shown in Table 4.2-11, the screening calculations predict that, under worst -case conditions, future CO concentrations at each intersection would not exceed the state 1-hour and 8-hour standards with or without the development of the Proposed Project. As a result, no significant Project -related impacts would occur relative to future carbon monoxide concentrations. Therefore, the Proposed Project would have a less than significant impact with respect to this criterion. Lyons Avenue/Dockweiler Drive Extension Project 4.2.

Pursuant to the study methodology identified in the SCAQMD's CEQA Air Quality Handbook, projects that are within the project -level emission thresholds identified above should be considered less than significant on a cumulative basis. Individual development projects that generate construction or operational emissions that exceed the SCAQMD recommended daily thresholds for project -specific impacts would be considered to cause or contribute to a cumulatively considerable increase in emissions for those pollutants for which the Basin is in non -attainment. Thus, as discussed in the Section above, because the construction -related emissions associated with the Proposed Project would not exceed the SCAQMD's recommended thresholds, the Proposed Project's construction emissions would not be cumulatively considerable. Therefore, cumulative air quality impacts would be less than significant. The Proposed Project would not generate any operational source emissions and thus would not contribute to cumulative emissions within the Basin. Therefore operational impacts would be less than significant on a cumulative basis. Lyons Avenue/Dockweiler Drive Extension Project 4.2.

The Construction Emission Management Plan shall require the use of Best Available Control Measures, as specified in Table 1 of SCAQMD's Rule 403. The Construction Emission Management Plan shall include the following additional elements: a. Use of water trucks or sprinkler systems in sufficient quantities to prevent airborne dust from leaving the site. When wind speeds exceed 15 mules per hour the operators shall increase watering frequency. b. Active sites shall be watered at least three times daily during dry weather. c. Suspend grading and excavation activities during windy periods (i.e., surface winds in excess of 25 miles per hour). d. Suspend the use of all constriction equipment during first -stage smog alerts. e. Application of non -toxic chemical soil stabilizers or apply water to form and maintain a crust on inactive construction areas (disturbed lands within construction projects that are unused for at least four consecutive days). f. Application of non -toxic binders to exposed areas after cut and fill operations and hydroseeded areas. g. Plant vegetative ground cover in disturbed areas as soon as possible and where feasible.

Operate street sweepers that comply with SCAQMD Rules 1186 and 1186.1 on roads adjacent to the construction site so as to minimize dust emissions. Paved parking and staging areas shall be swept daily. i. Scheduling truck deliveries to avoid peak hour traffic conditions, consolidating truck deliveries, and prohibiting truck idling in excess of 5 minutes. j. Reduce traffic speeds on all unpaved roads to 15 miles per hour or less. k. Pave or apply gravel on roads used to access the construction sites when possible. 1. Minimize idling time either by shutting equipment when not in use or reducing the time of idling to 5 minutes as a maximum. in. Limit, to the extent feasible, the hours of operation of heavy-duty equipment and/or the amount of equipment in use. 4.2-2 All off -road diesel -powered construction equipment greater than 50 hp shall meet the Tier 4 emission standards, where available. In addition, all construction equipment shall be outfitted with BACT devices certified by GARB. Any emissions control device used by the contractor shall achieve emissions reductions that are no less than what could be achieved by a Level 3 diesel emissions control strategy for a similarly sized engine as defined by CARB regulations. A copy of each unit's certified tier specification, BACT documentations, and GARB, SCAQMD, or ICAPCD operating permit shall be provided at the time of mobilization of each applicable unit of equipment. 4.2-3 An information sign shall be posted at the entrance to each construction site that identifies the permitted construction hours and provides a telephone number to call and receive information about the construction project or to report complaints regarding excessive fugitive dust generation. Any reasonable complaints shall be rectified within 24 hours of their receipt. 4.2-4 The contractor shall utilize low-VOC content coatings and solvents that are consistent with applicable SCAQMD and ICAPCD rules and regulations. 4.2.6 LEVEL OF SIGNIFICANCE AFTER MITIGATION The Proposed Project would result in less -than -significant impacts associated with regional construction and operational air quality emissions. Localized emissions of PM10 and PM25, however, would be significant and unavoidable. Lyons Avenue/Dockweiler Drive Extension Project 4.2. Air Quality SCH No. 2013082016 Page 4.2-31 4. ENVIRONMENTAL IMPACT ANALYSIS 3. BIOLOGICAL RESOURCES 43.1 INTRODUCTION The following section addresses the Proposed Project's potential to result in significant impacts upon biological resources, including vegetation and wildlife resources. The analysis presented below is based on the Biological Resources Assessment, Jurisdictional Delineation and Impact Assessment, Dockweiler Road Extension Project, Santa Clarita, California, prepared by Impact Sciences, Inc., dated April 2015 ("Biological Assessment"). The Biological Assessment is provided in Appendix D of this Draft EIR. 43.2 ENVIRONMENTAL SETTING Description of the Study Area The Project Site is located at the intersection of Lyons Avenue and Railroad Avenue and extends eastward towards the General Plan alignment for Dockweiler Drive towards The Master's University and northwest towards the intersection of 12'h Street and Arch Street. The Project Site also includes related infrastructure improvements that will include the closure of an at -grade crossing at the intersection of Railroad Avenue and 13'h Street. Due to the irregular shape of the Proposed Project, several terms are used to describe the Project Site in the Biological Assessment. "Project Site" is defined as the disturbance area associated with the Proposed Project inclusive of the road right-of-way and adjacent areas disturbed by grading. "Project Area" includes the Project Site as well as a 200-foot buffer occurring on either side of the grading limit line. The "Project Region" includes the Newhall, California US Geologic Survey (USGS) 7.5-minute quadrangle, in which the Project Site is located, as well as the following eight surrounding quadrangles: Mint Canyon, Green Valley, Warm Springs Mountain, Whitaker Peak, Val Verde, Santa Susana, Oat Mountain and San Fernando. Elevations on the Project Site range from approximately 1,260 to 1,285 feet and the Project Site totals approximately 6.67 acres. Approximately 2 acres of this area is already paved or otherwise developed. Figure 4.3-1, Project Location Map, depicts the Project Site location and topography. Existing land uses in the vicinity of the Project Site include railroad tracks and a train station to the south, industrial and commercial development to the southwest, west, and northwest and north. Rural residential land uses occur to the northeast and undeveloped open space occurs east of the Project Site.

April 2015 PARKER Figure 4.3-1 ENVIRONMENTAL CONSULTANTS Project Location Map City of Santa Clarita August 2017 Literature Search The literature search conducted in the Biological Assessment indicated several special -status plant and wildlife species have been recorded from the Project Region. Only observed species and those with a moderate to high potential of occurrence on the Project Site or area are described in the Biological Assessment. However, all species defined within a 9-quad search, including the Project Site, are presented, and analyzed in the Special Status Species Tables (See Appendices A and B of the Biological Assessment). Special status species include species listed as Endangered, Threatened, or Rare under the federal or state Endangered Species Acts, Candidate Species for listing as Endangered or Threatened, California Fully Protected Species, and, pursuant to State CEQA Guidelines Section 15380(d), all other species tracked by the California Natural Diversity Database (CNDDB) which are considered by the California Department of Fish and Wildlife (CDFW) to be those species of greatest conservation concern. Plant species with a California Rare Plant Rank (Rank) of 1 (plants presumed extinct in California, or Rare, Threatened, or Endangered in California and elsewhere), Rank 2 (plants that are Rare, Threatened, or Endangered in California but more common elsewhere), or Rank 4 (plants of limited distribution in California) are included in this definition. Plant species with a Rare Plant Rank of 3 (plants for which insufficient information is available to determine their status) are not included in this definition. Species tracked by the CNDDB are listed in CDFW's lists of Special Plants and Special Animals. Field Surveys On June 17, July 17, and October 10, 2013, on -site field surveys were conducted by Impact Sciences biologists to delineate jurisdictional resources, inventory wildlife and plants, and map vegetation associations that occur within the project site and area. The entire project area was traversed along meandering transects. Vegetation associations were mapped in the field using aerial photographs and direct observation. For the jurisdictional delineation, features within the project area were assessed for indicators of stream, riparian, or wetland functions. Plant taxonomy used in the delineation followed the current flora of California. Vegetation Communities Seven distinct native vegetation communities were identified within the Project Site. In descending order of prevalence, these include chamise chaparral, rubber rabbitbrush scrub, scale broom/mulefat scrub, California sagebrush/California buckwheat scrub, scale broom scrub, coast prickly pear scrub, and narrow -leaf willow thicket. Developed and disturbed areas were also mapped, and include developed/ornamental landscaping, cleared/disturbed areas, exotic trees, and components of the native plant communities listed above. Each of these vegetation communities is shown in Figure 4.3-2, Vegetation Communities, and described below.

This community is dominated by chamise along with gray California buckwheat (Eriogonum fasciculatum var. polifolium), occasional chaparral yucca (Hesperoyucca whipplei). This alliance dominates the southeastern portion of the Project Site and includes a small pocket of coast prickly pear cactus scrub (Opuntia littoralis). Disturbed Chamise Chaparral (0.32 acre): An area of Disturbed Chamise Chaparral Alliance also occurs in the southeastern portion of the Project Site, adjacent to cleared/disturbed areas. Rubber Rabbitbrush (Ericameria nauseosa) Scrub Alliance (0.74 acre): This Alliance is dominated by rubber rabbitbrush, along with occasional big sagebrush (Artemisia tridentata) and California buckwheat (Eriogonum fasciculatum) and occurs in three areas of the Project Site. Rubber rabbitbrush is a fast- growing shrub that develops quickly after disturbance. Scalebroom—Mulefat Scrub (Lepidospartum squamatum—Baccharis salicifolia Shrubland Alliance) (0.43 acre): Scalebroom-mulefat scrub occurs on the banks (0.32 acre) and in the active channel of Newhall Creek (0.11 acre). Dominant plants present within this alliance include scalebroom and mulefat, occurring together in densities ranging from 10 percent to 40 percent cover. Figure 4.3-2 illustrates the separation, but for the purposes of this discussion, it is considered one habitat. Vegetation is sparse within the Newhall Creek channel. The most common species include scalebroom and mulefat, together resulting in less than 10 percent cover. With the exception of a small cluster of narrow -leaf willow (described below), the creek channel is characterized as a scoured sandy streambed. California Sagebrush -California Buckwheat Scrub (Artemisia californica-Eriogonum fasciculatum Shrubland Alliance) (0.18 acre): The area identified as California Sagebrush -California Buckwheat Scrub supports approximately 80 percent native cover where it occurs on a south -facing slope above Newhall Creek in the southwestern portion of the Project Site. Sawyer and Keeler -Wolf describe this plant community as Artemisia californica-Eriogonum fasciculatum Shrubland Alliance since the dominant shrub is California sagebrush and the codominant shrub is California buckwheat. Other shrubs present include chamise (Adenostoma fasciculatum), black sage (Salvia mellifera), non-native grasses and forbs such as wild oats (Avena sp.), and brome (e.g., Bromus sp.). Disturbed California Sagebrush -California Buckwheat Scrub (1.28 acres): An additional area of disturbed California Sagebrush -California Buckwheat Scrub occurs near the center of the Project Site. This community has undergone disturbance in the recent past, evidenced by the sparse nature of the vegetation and influx of non-native species. Remnants of California sagebrush and California buckwheat remain, though the area is now co -dominated by non-native grasses and forbs including summer mustard (Hirschfeldia incana), tree tobacco (Nicotiana glauca) and yellow star thistle (Centaurea solstitialis). The weedy native cocklebur (Xanthium strumarium) is also present. Scalebroom Scrub (Lepidospartum squamatum Shrubland Alliance) (0.02 acre): Areas dominated by scalebroom are present on both sides of Newhall Creek in the south-western portion of the Project Site Lyons Avenue/Dockweiler Drive Extension Project 4.3 Biological Resources SCH No. 2013082016 Page 4.3-5 City of Santa Clarita August 2017 within a relatively flat area. This community includes a few scattered mulefat and big sagebrush (Artemisia tridentata) shrubs. Coast Prickly Pear Scrub - Opuntia littoralis Shrubland Alliance (0.015 acre): One small patch of coast prickly pear is found in the extreme southeast extent of the property, surrounded entirely by chamise chaparral. Narrow -Leaf (Sandbar) Willow Thickets - Salix exigua Shrubland Alliance (0.007 acre): Narrow -leaf willows occur in a small stand (25 feet x 12 feet) within the alignment of the proposed bridge. While this species is a wetland indicator, other wetland indicators are absent. The vegetation occurs on the opposite side of Newhall Creek from the ephemeral tributary, and likely receives periodic dry -season runoff from streets to the west. Coast Live Oak (0.008 acre): Two coast live oak trees (Quercus agrifolia) occur within the Proposed Project area along with one blue elderberry (Sambucus nigra ssp. caerulea). Developed/Ornamental Landscaping (1.98 acre): These areas support structures, pavement, or non- native ornamental landscaping associated with development. This is the second largest vegetation association within the Project Site. Two small clusters of non-native locust trees (Robinia sp.) are situated within the Project Site, between the railroad tracks and Newhall Creek in the southern portion of the Project Site, and occupy approximately 178 square feet (0.004 acre). These exotic (non-native) either volunteered or where planted. This species is considered undesirable because of its tendency to invade natural areas where it may out -compete native plants. Cleared/Disturbed Areas (0.46 acre): This area occurs in several small locations generally in the southern portion of the Project Site. These areas are nearly devoid of vegetation, supporting mostly open bare soil. Wildlife During the surveys conducted for the Biological Assessment weather was warm and clear, providing conditions suitable for high wildlife activity. However, due to the relatively small size of the Project Site and area, combined with the presence of nearby urban development and the associated human disturbance, wildlife diversity on the Project Site is relatively low. The only reptile observed on site was side -blotched lizard (Uta stansburiana). Tracks, scat, burrows, and other sign observed indicate the presence of California ground squirrel (Spermophilus beecheyi) and Botta's pocket gopher (Thomomys bottae). Common bird species recorded during the field surveys included mourning dove (Zenaida macroura), American crow (Corvus brachyrhynchos), California towhee (Melozone crissalis), house finch (Haemorhous mexicanus), and Say's phoebe (Sayornis saya). All of these species are relatively tolerant of human encroachment. Several additional avian species are expected to occur on site seasonally. Small rodents including Botta's pocket gopher (Thomomys bottae) and deer mouse (Peromyscus maniculatus) are likely present and evidence of California ground squirrel (Otospermophilus beecheyi) and evidence of coyote (Canis latrans) were observed. Lyons Avenue/Dockweiler Drive Extension Project 4.3 Biological Resources SCH No. 2013082016 Page 4.3-6 City of Santa Clarita August 2017 Wildlife Movement Habitat used by wildlife as a movement corridor generally link large areas of open space that are otherwise separated by rugged terrain, changes in vegetation, human disturbance, or the encroachment of urban development. The fragmentation of natural habitat creates isolated `islands' of vegetation that may not individually provide sufficient area to accommodate sustainable populations and can adversely impact genetic and species diversity. Corridors mitigate the effects of this fragmentation by: (1) allowing animals to move between remaining habitats, which allows depleted populations to be replenished and promotes genetic exchange with separate populations; (2) provide escape routes from fire, predators, and human disturbances, thus reducing the risk that catastrophic events (such as fire, flood, or disease) will result in population or species extinction; and (3) serving as travel paths for animals that require larger home ranges to meet their normal requirements of food, water and cover. The Project Site is generally surrounded on three sides by development, including road networks. However, Newhall Creek provides a passage through the developed areas between the Santa Clara River and the Angeles National Forest to the southeast. Stream corridors in general are considered important movement corridors for wildlife, because they provide water, food, and often cover by riparian vegetation for protection from predators. On and near the Project Site Newhall Creek does not flow year-round. Riparian vegetation on the Project Site is limited to sparse shrubs, and steep banks on the Project Site also limit available cover. However, Newhall Creek does provide, as stated above, a connection between the Santa Clara River and the Angeles National Forest to the southeast. Although, much of the length of the creek occurs adjacent to dense development and wildlife activity is expected to be somewhat limited, Newhall Creek is considered part of a wildlife movement or migration corridor that connects larger areas of natural open space. Special -Status Plant and Animal Resources Based upon review of the California Natural Diversity Database (CNDDB) database for special -status plant species of the Newhall, CA and eight adjacent quadrangles, 37 special -status plant and 39 special - status animal species have been reported from the region. The potential for special -status species to occur on the Project Site is based on the proximity of the Project Site to previously recorded occurrences in the CNDDB database, habitat requirements of each species, evaluation of on -site vegetation and habitat quality, topography, elevation, soils, surrounding land uses, and geographic ranges of special -status plant and wildlife species known to occur in the region. Potential special -status plant species that may occur on project site is summarized in Appendix A of the Biological Assessment, Special -Status Plant Species Recorded from the Project Region. Likewise, special status wildlife species recorded in the region that may occur on the Project Site are summarized in Appendix B of the Biological Assessment, Special -Status Wildlife Species Recorded from the Project Region. The occurrence potential described in Appendices A and B are classified according to the following: Lyons Avenue/Dockweiler Drive Extension Project 4.3 Biological Resources SCH No. 2013082016 Page 4.3-7 City of Santa Clarita August 2017 Not Expected: There is no suitable habitat present on the proposed project site (i.e., habitats on the proposed project site are clearly unsuitable for the species requirements [e.g., foraging, breeding, cover, substrate, elevation hydrology, plant community, disturbance regime, etc.]). The species has an extremely low probability of being found on the proposed project site and no further surveys are required. Low Potential: Either significantly limited quantity and/or quality of suitable habitat is present on the proposed project site (i.e., not enough area of the habitat is present to support the species, few of the habitat components meeting the species requirements are present and/or the majority of habitat on the proposed project site is unsuitable or of very low quality). There are no or few recent known records of occurrence in the near vicinity of the proposed project site. The species has a low probability of being found on the proposed project site and no further surveys are required. Moderate Potential: Some suitable habitat is present on the proposed project site (i.e., some of the habitat components meeting the species requirements are present and/or the quantity the habitat on the proposed project site is marginal). Additionally, there are known records of occurrences in the region of the proposed project site, but not necessarily in the immediate vicinity. The species has a moderate probability of being found on the proposed project site and additional surveys may be required. High Potential: Suitable quantity and quality of habitat is present on the proposed project site (i.e., all habitat components meeting the species requirements are present and/or habitat(s) on the proposed project site is highly suitable or of high quality). Additionally, there are recent known records of occurrences in the vicinity of the proposed project site. Species having a high probability of being found on the proposed project site may require additional surveys to fully determine presencelabsence. Present: Species was observed on the proposed project site during surveys associated with this report or by other persons. Special -Status Plants Based on habitat conditions and the small size of Project Site, only general botanical surveys were conducted on the Project Site and area. Focused rare plant surveys were performed adjacent to and east of the Project Site. The only special -status plants observed during the field investigations were two coast live oaks. No other special -status plants are considered to have a high potential for occurrence within the Project Site. Native oak trees are protected under City of Santa Clarita Oak Tree Ordinance (Ordinance No. 89-10, passed by the City Council on April 25, 1989) and the City's Oak Tree Preservation and Protection Guidelines (adopted September 11, 1990). The City of Santa Clarita's Oak Tree Preservation ordinance (Unified Development Code § 17.51.040) requires the preservation of all healthy oak trees and that Lyons Avenue/Dockweiler Drive Extension Project 4.3 Biological Resources SCH No. 2013082016 Page 4.3-8 City of Santa Clarita August 2017 removal, cutting, pruning, relocation, damage, or encroachment into the protected zone of any oak trees measuring 6 inches or larger in circumference (DBH, diameter at breast height) on public or private property can only be done in accordance with a valid oak tree permit issued by the City. Special -Status Wildlife No special -status wildlife species were directly observed during field investigations conducted on the Project Site or area. Although Newhall Creek traverses the Project Site, it is considered a seasonal drainage, and it is apparent within the Project Site, when flows do occur, they are rapid enough to scour the channel. Therefore, none of the special -status fish defined in Appendix B of the Biological Assessment are expected to occur on site, with the possible exception of a potential temporary presence after storm events. Likewise, aquatic conditions are not suitable for special -status amphibians defined in Appendix B of the Biological Assessment. In most areas of the Project Site the banks of Newhall Creek are too severe for amphibians to traverse. As such, they too are expected to have no more than a low potential for occurrence. Some of the more highly motile species such as birds and bats may briefly and infrequently occur on site to forage. However, there is no on -site habitat of a size or quality that could reasonably support a sustainable resident population of any of the special -status wildlife species identified in Appendix B of the Biological Assessment. Notwithstanding, one special -status reptile is considered to have a moderate potential to occur on site. Silvery legless lizard (Anniella pulchra pulchra), California Species of Special Concern. This small lizard is often mistaken for a snake or worm since, as it has no limbs. Silvery legless lizard spends most of its life below surface soils where it forages on insects and larvae. It is most commonly found in and around the roots of trees and shrubs, often beneath leaf litter where its prey is most abundant. Moisture is a key ingredient in its habitat requirement. Silvery legless lizards will dig deeper into the soils to reach the correct moisture level. As such, this species is rarely observed unless one actively seeks it out. Though apparently very dry at the surface, some of areas within the Project Site may have sub -surface soils with the moisture content necessary to support this species. Therefore silvery legless lizard is considered to have a moderate potential for occurrence on the proposed Project Site. Jurisdictional Waters, Streambed, and Riparian Resources The portion of Newhall Creek present on the proposed Project Site is under the jurisdictional authority of federal and state regulatory agencies. Impacts to "Waters," streambeds and adjacent riparian vegetation, as defined in the regulations cited below, typically require authorizations from these agencies. Regulatory agencies and the limits of their jurisdiction are discussed below. Lyons Avenue/Dockweiler Drive Extension Project 4.3 Biological Resources SCH No. 2013082016 Page 4.3-9 City of Santa Clarita August 2017 Regulatory Setting Federal Regulations U.S. Army Corps of Engineers (ACOE) Federal regulations of "Waters of the United States" stem from Section 10 of the Federal Rivers and Harbors Act of 1899, enacted to regulate activities within navigable waters. In 1972, the federal Clean Water Act was passed. This act regulates discharges into Waters of the United States and Section 404 of this act regulates activities including fills placed into wetlands that are adjacent to navigable waters. Waters of the United States are defined in 33 CFR 328.3(a) as: • All waters that are currently used, were used in the past, or may be susceptible to use in interstate or foreign commerce, including all waters that are subject to the ebb and flow of the tide. • All interstate waters including interstate wetlands. • All other waters such as intrastate lakes, rivers, streams (including intermittent streams), mudflats, potholes, wet meadows, playa lakes, or natural ponds, the use, degradation or destruction of which could affect interstate or foreign commerce including any such waters. • Waters that are or could be used by interstate or foreign travelers for recreational or other purposes. • Waters from which fish or shellfish are or could be taken and sold in interstate or foreign commerce. • Waters that are used or could be used for industrial purpose by industries in interstate commerce. • All impoundments of waters otherwise defined as Waters of the US under the definition. • The territorial seas. • Tributaries of Waters of the US. • Wetlands adjacent to Waters of the US. USACE jurisdiction in non -tidal waters typically extends to the ordinary high water mark (OHWM). The OHWM for intermittent streams, for example, can be determined by "the fluctuations of water as indicated by physical characteristics such as clear, natural lines impressed on the bank, shelving, changes in the character of soil, destruction of terrestrial vegetation, the presence of litter and debris, or other appropriate means that consider the characteristics of the surrounding areas" (33 CFR 328.3(e)). In and areas of the southwest, the OHWM may occur at a lower level than where the typical physical indicators are present, due to unusually high flows not occurring on a typical annual cycle (Allen, et al. 2001). Most impacts to areas delineated as Waters of the United States, if determined to be jurisdictional by the USACE, require a project to obtain approval under the authority of the Clean Water Act and its implementing regulations. Lyons Avenue/Dockweiler Drive Extension Project 4.3 Biological Resources SCH No. 2013082016 Page 4.3-10 City of Santa Clarita August 2017 State Regulations California Department of Fish and Wildlife (CDFW) The State of California regulates water resources under Sections 1600 to 1619 of the Fish and Game Code of California. Section 1602 mandates that: An entity may not substantially divert or obstruct the natural flow of, or substantially change or use any material from the bed, channel, or bank of any river, stream, or lake or dispose of debris, waste, or other material where it may pass into any river stream, or lake. Unless certain requirements are met, CDFW considers most natural drainages to be streambeds unless it can be demonstrated otherwise. Streambeds are defined in the California Code of Regulations Title 14, Chapter 1, Section 1.72 as follows: A stream is a body of water that flows at least periodically or intermittently through a bed or channel having banks and that support fish or other aquatic life. This includes watercourses having surface or subsurface flow that supports or has supported riparian vegetation. CDFW jurisdiction includes ephemeral, intermittent, and perennial watercourses, and is often extended to the limit of riparian habitats that are located contiguous to the water resource that function as part of the watercourse system. In this analysis, the area generally corresponding to the limit of riparian habitats located contiguous to the water resource is referred to as the "resource line." Section 2785(e) of the Fish and Game Code of California states: Riparian habitat means lands which contain habitat which grows close to and which depends on soil moisture from a nearby freshwater source. Local Regulations Regional Water Quality Control Board Section 401 of the Federal Clean Water Act authorizes the State of California to certify federal permits and licenses. The state's implementing regulations to conduct certifications are codified under the California Code of Regulations Title 23 Waters, Sections 3830-3869. Projects qualifying for an ACOE Section 404 Permit must submit materials for review to the appropriate Regional Water Quality Control Board (RWQCB) and request a Section 401 Certification. Much of the same information (project description, potential impacts, and mitigation measures) necessary to apply for ACOE Section 404 and Fish and Game Code Section 1603 Permits is required for the Section 401 Certification. Direct and indirect impacts on wetland and riparian areas may also be subject to the jurisdiction of several additional state and federal agencies, including the Los Angeles RWQCB.

A map illustrating the vegetation and jurisdictional features in the survey area is depicted in Figure 4.3-3. Two jurisdictional features are defined within the Project Site, area and region: Newhall Creek. Upstream of its confluence with Placerita Creek and the south fork of the Santa Clara River. This creek is mapped by the USGS as a "blue -line" intermittent stream. On and near the Project Site the direction of flow is from southeast to northwest. Banks of the creek are nearly vertical, with the south bank containing artificial fill (pieces of concrete and asphalt). Railroad tracks and Railroad Avenue are situated to the west, beyond the top of the bank. Areas immediately east of the creek are vacant except for an industrial yard northeast of the proposed bridge location. No surface water was present during the April survey and sparse vegetation cover within the channel indicates frequent scour during the rainy season. Therefore, this wetland feature on the Project Site is best described as an intermittent riverine, relatively permanent water ("RPW") that has seasonal continuous flow, is a tributary to the Santa Clara River which flows into the Pacific Ocean, and can be defined as a traditionally navigable water (TNW). On the Project Site, vegetation and surface features indicate that seasonal flows migrate across the entire channel, which averages 35 feet in width at the base (Federal jurisdiction). The distance between the tops of the banks (limits of State jurisdiction) average approximately 100 feet. No indicators of prolonged water saturation or ponding, such as surface mud cracks, were observed on -site during the field survey. 2. Un-named ephemeral tributary to Newhall Creek. This narrow tributary is about 3.5 feet in width at its base (Federal jurisdiction) and is entirely within State jurisdiction over Newhall Creek. It is assumed that flow from this tributary enters the project area from a culvert underneath the railroad tracks and Railroad Avenue (this could not be confirmed during the survey due to presence of a homeless camp at the presumed culvert location). The distinct bed and bank structure of this feature, and regional topography, indicate this tributary is more than a "gully" resulting from localized erosion. Wetland indicators are absent from this feature. Appendix C of the Biological Assessment provides details regarding the vegetation occurring within the delineation survey boundaries. Of the vegetation identified in this area, only narrow -leaf willow thicket is a wetland indicator (Salix exigua — Facultative Wet). However, it is concluded that this thicket is probably not a jurisdictional wetland at the Federal or State level. Wetland Determination Federal Hydrology and soils present in the Project Site and area (floodplains/gravel bars and sand) are naturally problematic for wetland delineation. The following paragraphs include excerpts (in italics) from the Arid Lyons Avenue/Dockweiler Drive Extension Project 4.3 Biological Resources SCH No. 2013082016 Page 4.3-13 City of Santa Clarita August 2017 West supplement of the wetland determination procedure for problematic sites where soils may meet the definition of a hydric soil but do not exhibit typical indicators. Our observations are described for each step of the procedure. 1. Verify that one or more indicators of hyrophytic vegetation are present or that the vegetation is disturbed or problematic. If so, proceed to step 2. Site observations: Narrow -leaf willow has an indicator ranking for the Arid West of Facultative Wetland. Therefore, it can be concluded hydrophytic vegetation is present. 2. Verify that at least one primary or two secondary indicators of wetland hydrology are present or that indicators are absent due to disturbance or other factors. If so, proceed to step 3. If indicators of hydrophytic vegetation and/or wetland hydrology are absent, then the area is probably no -wetland and no further analysis is required. Site observations: No other primary indicators of wetland hydrology are present. Only one secondary indicator of wetland hydrology (dominance of Facultative Wet vegetation) is present. Based on this information, and the observation that redoximorphic soil features are sparse and, where present, are faintly expressed, it can be concluded that the willow thicket (300 square feet or 0.007 acre) is probably not a Federally jurisdictional wetland. Unfortunately, the Arid West procedure does not allow for a more definitive conclusion. State According to the wetland definition at the State level, it is concluded that the narrow -leaf willow thicket would not meet the definition of wetland. While narrow -leaf willow is a hydrophyte, there is no evidence of continuous or recurrent saturation of the upper substrate and no evidence of anaerobic conditions are present. Non -Wetland Jurisdiction The proposed bridge will impact Newhall Creek in a section of the creek that is classified as "riverine and relatively permanent water, with continuous flow at least seasonally". The bridge may also impact a narrow, ephemeral tributary to Newhall Creek. The extent of permanent and temporary construction impacts need to be known in order to provide a more precise analysis of impacts. 31L1u-1 DION 111 010 17X�1 _1 Methodology Direct impacts of a proposed project on biological resources typically involve the loss, modification, or disturbance of natural habitat (i.e., plant communities or other naturally occurring areas) which in turn, directly and indirectly affect plant and wildlife species dependent on that habitat. The significance of Lyons Avenue/Dockweiler Drive Extension Project 4.3 Biological Resources SCH No. 2013082016 Page 4.3-14 City of Santa Clarita August 2017 potential impacts on biological resource is determined by an evaluation of the overall biological value of a habitat area in comparison with significance threshold criteria that are described below. The relative value of each of the plant communities present on site is measured by such factors as disturbance history, biological diversity, importance to particular plant and wildlife species, uniqueness or sensitivity status, as well as the surrounding environment and the presence of special -status resources. The significance of impacts with respect to direct impacts on individuals or populations of plant and animal species takes into consideration the number of individual plants or animals potentially affected, how common or uncommon the species is both on the Project Site and from a regional perspective, and the sensitivity status if the species is considered special status by resource agencies. These factors are evaluated based on the results of on -site biological surveys and studies, results of literature and database reviews, and established and recognized ecological and biodiversity theories and assumptions. CEQA Guidelines Thresholds of Significance According to Checklist Questions IV(a) through V(f) in Appendix G of the State CEQA Guidelines, a project may have a significant environmental impact if it were to • Have a substantial adverse effect, either directly or through habitat modifications, on any species identified as a candidate, sensitive, or special -status species in local or regional plans, policies, or regulations or by the CDFW or USFWS; • Have a substantial adverse effect on any riparian habitat or other sensitive natural community identified in local or regional plans, policies, or regulations or by the CDFW or USFWS; • Have a substantial adverse effect on federally protected wetlands as defined by Section 404 of the Clean Water Act (including, but not limited to, marsh, vernal pool, coastal, etc.) through direct removal, filling, hydrological interruption, or other means; • Interfere substantially with the movement of any native resident or migratory fish or wildlife species or with established native resident or migratory wildlife corridors, or impede the use of native wildlife nursery sites; • Conflict with any local policies or ordinances protecting biological resources, such as a tree preservation policy or ordinance; or • Conflict with the provisions of an adopted Habitat Conservation Plan, Natural Community Conservation Plan, or other approved local, regional, or state Habitat Conservation Plan. Project Impacts Habitat Modification Vegetation As described above, and depicted in Figure 4.3-2, eight vegetation communities occur on the Project Site that include: California Sagebrush -California Buckwheat Scrub, Disturbed California Sagebrush - California Buckwheat Scrub, Scale Broom—Mulefat scrub, Scalebroom Scrub, Active Channel, Exotic Trees, Developed/ Ornamental Landscaping, and Cleared. Site grading plans indicate that within the Project Site 2.32 acres of vegetation would be removed (100 percent of the vegetation resources present). Lyons Avenue/Dockweiler Drive Extension Project 4.3 Biological Resources SCH No. 2013082016 Page 4.3-15 City of Santa Clarita August 2017 Of the vegetation communities impacted Disturbed California Sagebrush -California Buckwheat Scrub is the dominant plant community present by area and approximately 0.63 acre of this habitat would be lost through site grading and project implementation. Due to its proximity to adjacent developed areas, the Project Site has been subject to historic disturbances. Combined with its small size (2.32 acres), invasive plant species observed on the Project Site (e.g. mustard, tree tobacco, cocklebur, yellow star thistle) indicate a high percentage of plants that are generally associated with ruderal or highly disturbed places. As concluded in the Biological Assessment, the loss of 2.32 acres of vegetation on the Project Site is considered adverse. However, due to the disturbance history, its small size, the lack of sensitive plant communities, the lack of structure for wildlife, and high percentage of invasive and non-native plant species generally associated with disturbed areas, impacts associated with the loss of 2.32 acres of vegetation present on -site is considered less than significant. Special -Status Plants As discussed above, the only special -status plants observed during the field investigations were two coast live oaks. No other special -status plants are considered to have a high potential for occurrence within the Project Site. Native oak trees are protected under City of Santa Clarita Oak Tree Ordinance (Ordinance No. 89-10, passed by the City Council on April 25, 1989) and the City's Oak Tree Preservation and Protection Guidelines (adopted September 11, 1990). A permit is required for encroachment into the Protected Zone, defined as 5 feet outside the dripline and further defined as extending no less than 15 feet outward from the trunk of an oak tree. The City of Santa Clarita requires that all potential impacts to oak trees be preceded by an application to the City that includes a detailed oak tree report and that loss of or damage to protected oaks be mitigated at a minimum 2:1 ratio. Based upon the development and grading footprint of the proposed project as depicted in Figure 2.9, Proposed Site Plan at Lyons Avenue, it has been determined that the 2 oak trees that occur within the project limits would be required to be removed for project construction. The removal of or encroachment to oak trees as a result of project construction would be considered a significant impact under both the City of Santa Clarita and CEQA. Replacement oak trees would be planted in the number necessary to comply with the requirements stipulated in the Oak Tree Permit issued by the City. With approval of the required oak tree permits, and implementation of Mitigation Measure 4.3-7, impacts upon the loss or pruning of any oak tree would be reduced to less than significant levels. Wildlife Common Wildlife Construction activity and grading operations of the Proposed Project would disturb and/or threaten the survival of common wildlife species present. Some species would be expected to relocate to other areas of similar habitat within the local area. However, wildlife that emigrate to off -site areas are vulnerable to mortality by predation, potential conflicts with people and cars, and unsuccessful competition for food Lyons Avenue/Dockweiler Drive Extension Project 4.3 Biological Resources SCH No. 2013082016 Page 4.3-16 City of Santa Clarita August 2017 and territory. It is expected that species of low mobility (particularly small mammals, amphibians, and reptiles) would be lost during site preparation, grading and construction. Site grading and project implementation would eliminate approximately 2.32 acres of natural habitat present on -site, and would result in an incremental reduction in native wildlife species abundance and diversity. However, due to nearby urban development and the associated human disturbance, field investigations indicate wildlife diversity and abundance on the Project Site is relatively low. The only reptile observed on site was side -blotched lizard (Uta stansburiana). Tracks, scat, burrows, and other sign observed indicate the presence of California ground squirrel (Spermophilus beecheyi) and Botta's pocket gopher (Thomomys bottae). Small rodents including deer mouse (Peromyscus maniculatus) are likely also present and evidence of coyote (Canis latrans) was observed. Common bird species recorded during the field surveys included mourning dove (Zenaida macroura), American crow (Corvus brachyrhynchos), California towhee (Melozone crissalis), house finch (Haemorhous mexicanus), and Say's phoebe (Sayornis saya). All of these species are relatively tolerant of human encroachment. Several additional avian species are expected to occur on site seasonally. Because of the relatively common occurrence of these wildlife species that would be displaced or lost, project implementation is not expected to cause a current wildlife population on or adjacent to the Project Site to drop below self-sustaining levels. Therefore, impacts to common wildlife species is not considered significant. Special -Status Wildlife An assessment of biological resources present on the Project Site determined that one special -status wildlife species has a moderate potential to occur within the Project Site and could be directly impact through project implementation. Silvery legless lizard is a California species of special concern. On the Project Site, some limited habitat suitable for this species is present in the sandier terraces of Newhall Creek and possibly within the areas of scrub habitat north of the creek. This species is almost completely fossorial (i.e., occurring beneath the surface) and is dependent upon moisture levels in the soils where they live. During dry periods they will burrow deeper to find the necessary levels of moisture. As such, silvery legless lizard can be difficult to find, especially in dry seasons or years. Although sands within the Newhall Creek bed may currently be suitable for silvery legless lizard, they are unlikely to occur within the creek itself as it periodically supports storm flows and would scour any away legless lizards that could be seeking refuge. Therefore, the only suitable habitat remaining is a small area above the ordinary high water mark, north of the creek. This area may support individual species of silvery legless lizard, but is not likely to support a sustainable population. The grading plan indicates the areas north of the Project Site would be disturbed during grading and project construction. Although it can be concluded that bridge construction associated with the Proposed Project would not impact populations of silvery legless lizard, disturbances associated with grading and implementation of the road extension may impact individuals of this California species of special concern. Therefore, impacts are considered significant without mitigation. Lyons Avenue/Dockweiler Drive Extension Project 4.3 Biological Resources SCH No. 2013082016 Page 4.3-17 City of Santa Clarita August 2017 Additionally, most native bird species when nesting, are protected by the Migratory Bird Treaty Act and the California Fish and Game Code, which prohibit the take (defined as destroy, harm, harass, etc.) of bird nests with eggs or young. Project -related activities associated with site preparation and construction could result in the direct loss of active nests or the abandonment of active nests by adult birds should grading occur during the nesting season. The loss of active bird nests would be in conflict with the Migratory Bird Treaty Act and the California Fish and Game Code. As such, impacts to active nests are a significant impact without mitigation. Without mitigation, the Proposed Project could result in potentially significant impacts to silvery legless lizard and active nesting birds. Implementation of Mitigation Measures 4.3-1 and 4.3-2 would reduce impacts to silvery legless lizard and nesting birds to a less than significant level. Federally Protected Wetlands Based on field investigations, a small area of narrow -leaf willow thicket (300 square feet or 0.007 acre) is present. Where it occurs on -site, redoximorphic soil features are sparse and faintly expressed and as such the narrow -leaf willow thicket present on the Project Site is probably not a Federally jurisdictional wetland. Further, according to the wetland definition at the State level, narrow -leaf willow thicket present on -site would not meet the criteria of wetland as defined by the State of California. While narrow -leaf willow is a hydrophyte, there is no evidence of continuous or recurrent saturation of the upper substrate and no evidence of anaerobic conditions are present. Two jurisdictional features do occur within the Project Site and area. Newhall Creek and a small ephemeral drainage that is a tributary to Newhall Creek occur on the Project Site and fall under the jurisdiction of the CDFW. Although these jurisdictional features do not support riparian vegetation or sensitive wetland resources, Newhall Creek does support features that lie within the jurisdiction of CDFW. As discussed above, the proposed bridge and associated infrastructure would result in both temporary and permanent impacts to areas of the Newhall Creek and its associated tributary and are classified as "riverine and relatively permanent water, with continuous flow at least seasonally" and as such are under CDFW jurisdiction. Without consultation with, and a formal agreement with CDFW, such impacts would be in violation of the Fish and Game Code and, are considered a significant impact. Without mitigation, the project would result in potentially significant impacts to CDFW jurisdictional resources (i.e. Newhall Creek and its associated tributary). Mitigation Measure 4.3-3 would reduce impacts to jurisdictional resources to a less than significant level. Wildlife Movement and Corridors The Project Site is generally surrounded on three sides by development and road networks. However, Newhall Creek does extend through the site and provides a passage through developed areas between the Santa Clara River and the Angeles National Forest to the southeast. Stream corridors in general are considered important movement corridors for wildlife, because they provide water, food, and often cover by riparian vegetation for protection from predators. On and near the Lyons Avenue/Dockweiler Drive Extension Project 4.3 Biological Resources SCH No. 2013082016 Page 4.3-18 City of Santa Clarita August 2017 proposed Project Site Newhall Creek does not flow year-round. Vegetation on the Project Site is limited to sparse shrubs, and steep banks on the Project Site limit cover. However, Newhall Creek does provide, as stated above, a connection between the Santa Clara River and the Angeles National Forest. Though much of the length of the creek occurs adjacent to dense development and wildlife activity is expected to be somewhat limited, Newhall Creek is considered part of a wildlife movement or migration corridor that connects larger areas of natural open space. To limit impacts to wildlife movement, four 25-foot wide and 8-foot deep openings in a concrete box bridge with 80-foot wide soft base and 2:1 protected side slopes is proposed where the proposed roadway extension crosses Newhall Creek. As designed, this bridge would not result in any barrier to wildlife movement and would serve to protect Newhall Creek as a functioning wildlife movement corridor. The project as proposed would not result in significant impacts to wildlife movement. Construction Activity Project construction (particularly site clearing and grading operations and implementation of the road surface) would have the potential to impact surrounding areas including adjacent plant communities and plant and animal species. Specifically, these impacts can include displacement and disturbance of wildlife, which could result in possible nest or den abandonment during the breeding season, siltation and erosion into drainages, excessive dust accumulation on vegetation that could result in the degradation or loss of some plant species, and soil compaction. Construction -related activities could have adverse effects on plant and wildlife habitat, and together, would be considered a significant impact. Implementation of Mitigation Measure 4.3-4 would reduce these construction -related impacts to less a less than significant level. Operation Increase in Populations of Non -Native Species Subsequent to project completion, the number of non-native plant and wildlife species occurring in the vicinity of the roadway alignment would be expected to increase. These species are more adapted to urban environments could potentially displace native species because of their ability to compete more effectively for resources. Non-native plants tend to be more adaptable to urban or disturbed settings and can out -compete native plants for available resources. However, observations indicate historical and ongoing development in the vicinity of the Project Site have already supported continual and ongoing increases and proliferation of non-native plant and wildlife species populations in the area adjacent to the Project Site. Consequently, the Proposed Project is not expected to substantially increase the distribution of non-native plants and wildlife in adjacent open space areas situated to the east. Therefore, impacts to the remaining natural areas as a result of potential increases in non-native plants and wildlife resulting from project implementation are expected to be less than significant, given compliance with Mitigation Measure 4.3-5. Lyons Avenue/Dockweiler Drive Extension Project 4.3 Biological Resources SCH No. 2013082016 Page 4.3-19 City of Santa Clarita August 2017 Increased Light and Glare It is logical to assume that nighttime headlamp illumination would increase in areas adjacent to the Project Site. Nighttime light can disturb breeding and foraging behavior and can potentially alter breeding cycles of birds, mammals, and nocturnal invertebrates. Headlamp illumination could deter some animal species, especially the larger mammals, from using Newhall Creek as a wildlife movement corridor. If uncontrolled, such light could adversely impact the composition and behavior of the animal species that occur in these areas. The Project Site is currently surrounded on three sides by development, and much of the Project Site and nearby natural area already receives some nighttime illumination from the adjacent urban areas. However, the Proposed Project would increase light and glare effects proximal to the Newhall Creek corridor. Mitigation Measure 4.3-6 would decrease this impact to less than significant. Stormwater and Urban Runoff It is expected that stormwater runoff would be limited to pavement runoff during periodic storm events. Runoff from paved surfaces can increase eutrophication, deplete oxygen levels, increase long-term buildup of toxic compounds and heavy metals, and other adverse effects to biological resources associated with aquatic systems. Although this impact is not quantifiable, it is reasonable to assume runoff could substantially affect special -status species potentially occurring downstream from the Project Site and incrementally diminish habitat values for fish, wildlife, or plants, and degrade the quality of the environment. As described above, any runoff that flows into the Newhall Creek could result in increased eutrophication, depleted oxygen levels, long-term build-up of toxic compounds and heavy metals downstream as Newhall Creek connects to the Santa Clara River. Although potentially significant, the City's standard stormwater requirements are specifically designed to minimize these effects. Therefore, with implementation of the required design criteria, impacts to Newhall Creek resulting from Stormwater runoff would be less than significant. 43.4 CUMULATIVE IMPACTS As discussed above, the development of the Project Site would potentially result in impacts to biological resources if left unmitigated. The outlined mitigation measures would reduce those impacts to a less than significant level. There are no proposed developments in the immediate vicinity of the site. The only exception to this would be The Masters University project situated to the east, which is currently being evaluated. However, the impacts from both The Masters University project (which are being evaluated within a separate EIR) and the Dockweiler Road extension that is the subject of this analysis have been previously evaluated as part of the City's General Plan. The extension of Dockweiler Road would not be growth inducing as this project is consistent with the City's General Plan for this area. Therefore, development associated with the proposed project and other development in the vicinity of the Project Site in the City Santa Clarita, would not result in a significant cumulative impact related to biological resources. Lyons Avenue/Dockweiler Drive Extension Project 4.3 Biological Resources SCH No. 2013082016 Page 4.3-20 City of Santa Clarita August 2017 43.5 MITIGATION MEASURES With incorporation of the following Mitigation Measures, impacts associated with the Proposed Project would be mitigated to a less than significant level. The Mitigation Measures are defined below: 4.3-1 The applicant shall retain a qualified biologist with a CDFG Scientific Collection Permit and Memorandum of Understanding to conduct preconstruction surveys for the silvery legless lizard within the Project Site and area. Should this species be located on the Project Site during preconstruction surveys all individuals shall be relocated, with the concurrence of the City and CDFW, to an approved site with suitable habitat. Surveys and relocation of silvery legless lizard may occur prior to construction; however, focused surveys must occur within 30 days prior to construction. Survey and relocation methods shall be approved by CDFW prior to commencement of grading. 4.3-2 Active nests of native bird species are protected by the Migratory Bird Treaty Act (16 U.S.C. 704) and the California Fish and Game Code (Section 3503). If activities associated with construction or grading are planned during the bird nestingibreeding season, generally January through March for early nesting birds (e.g., Coopers hawks or hummingbirds) and from mid -March through September for most bird species, the applicant shall have a qualified biologist conduct surveys for active nests. The project management shall endeavor to avoid the breeding season. In the event it is not feasible to avoid the nesting season, a qualified biologist shall perform weekly nesting bird surveys beginning 30 days prior to initiation of ground -disturbing activities, with the last survey conducted no more than three days prior to the start of clearance/construction work. If ground -disturbing activities are delayed, additional pre - construction surveys shall be conducted so that no more than three days have elapsed between the survey and ground -disturbing activities. Surveys shall include examination of natural habitat for nesting birds. Several bird species such as killdeer and night hawks are known to nest on bare ground. Protected bird nests that are found within the construction zone shall be protected by a buffer deemed suitable by a qualified biologist, and verified by CDFW. Typically, a 300-foot buffer is required for most species and a 500-foot buffer for raptor species. Buffer areas shall be delineated with orange construction fencing or other exclusionary material that would inhibit access within the buffer zone. Installation of the exclusionary material delineating the buffer zone shall be verified by a qualified biologist prior to initiation of construction activities. The buffer zone shall remain intact and maintained while the nest is active (i.e., occupied or being constructed by the adults bird(s)) and until young birds have fledged and no continued use of the nest is observed, as determined by a qualified biologist. 4.3-3 Prior to project construction, the following is required to mitigate impacts to jurisdictional resources: Lyons Avenue/Dockweiler Drive Extension Project 4.3 Biological Resources SCH No. 2013082016 Page 4.3-21 City of Santa Clarita August 2017 a. Areas of impact proposed by the project shall be calculated and permits for these proposed impacts shall be obtained (the discharge of fill into ACOE jurisdictional areas will require a permit pursuant to Section 404 of the Clean Water Act and a 401 Certification from the State Water Resources Control Board, and any modification to a streambed, [analysis states none is present], will require a streambed alteration agreement from CDFW pursuant to Section 1600 of the California Fish and Game Code). Both the streambed alteration agreement and the 401 and 404 permits will required specific mitigations for any impacts within their respective jurisdictions. b. Because the proposed bridge is a `span' design, it does not require footings within the bed of the stream. However, plan designs do include approximately 450 feet of bank stabilization on both sides of the stream that would lie within CDFW, ACOE and Regional Water Quality Control Board jurisdiction. Since little vegetation exists within this drainage, it is uncertain what mitigation these regulatory agencies may require. c. The stream in the impacted area would not be conductive to re -vegetation as the area of the project is deeply incised with little existing vegetation and newly planted vegetation would likely be washed away with the next storm event. d. Mitigation can be completed off site. Because there is essentially no riparian vegetation being removed with implementation of this project, revegetation off site, in a location approved by the City and CDFW, would be accomplished at a 1:1 area ratio. e. Upon City and agency approval of a suitable location, a detailed restoration plan shall be prepared that provides a planting palette, planting methods, and irrigation plan (as appropriate). The plan will also include a 5-year monitoring effort to ensure success of the restoration effort. The monitoring plan will include monitoring methods, monitoring frequency, success criteria, and contingency actions should the success criteria not be met for any reason. Annual monitoring reports shall be provided to both CDFW and the City. 4.3-4 The following guidelines shall be implemented to minimize impacts on remaining biological resources on the site as a result of construction and grading activities and to ensure that potential impacts on these resources will remain less than significant. A City -approved biologist shall be retained by the applicant as a construction monitor to ensure that incidental construction impacts on retained biological resources are avoided or minimized. Responsibilities of the construction monitor shall include the following: • Attend all pre -grading meetings to ensure that the timing and location of construction activities do not conflict with mitigation requirements. • Conduct meetings with the contractor and other key construction personnel, describing the importance of restricting work to within the project boundaries and Lyons Avenue/Dockweiler Drive Extension Project 4.3 Biological Resources SCH No. 2013082016 Page 4.3-22 City of Santa Clarita August 2017 outside of the preserved areas. The monitor shall also work with the contractor to determine the most appropriate staging/storage areas for equipment and materials. • Guide the contractor in marking/flagging the construction area limits, in accordance with the final approved grading plan. • Periodically and routinely visit the site during construction to coordinate and monitor compliance with the above provisions. The construction contractor shall install temporary erosion control measures to reduce impacts to and protect on site drainages from excess sedimentation, siltation, and erosion. These measures shall consist of minimization of existing vegetation removal; the use of temporary soil covers, such as hydro -seeding with native species, mulch/binder and erosion control blankets to protect exposed soil from wind and rain erosion; and/or the installation of silt fencing, berms, and dikes to protect storm drain inlets and drainages. No changing of oil or other fluids, or discarding of any trash or other construction waste materials shall occur on the Project Site. Vehicles carrying supplies, such as concrete, shall not be allowed to empty, clean out, or otherwise place materials into natural areas on or immediately adjacent to the site. Any equipment or vehicles driven and/or operated within or adjacent to drainages shall be checked and maintained daily, to prevent leaks of materials that if introduced to water could be deleterious to aquatic life. No equipment maintenance shall be conducted within the drainage channels or within 50 feet of channels. (Fuel -powered vehicles and equipment shall not be left idling or operated beyond periods need to accomplish approved tasks.) Construction personnel shall be prohibited from entry into areas outside the designated construction area, except for necessary construction related activities, such as surveying. All such construction activities in or adjacent to remaining open space areas shall be coordinated with the project biologist. Standard dust control measures of the South Coast Air Quality Management District shall be implemented to reduce impacts on nearby plants and wildlife. This includes a variety of options to reduce dust including replacing ground cover in disturbed areas as quickly as possible, watering active sites regularly, and suspending all excavating and grading operations during periods of high winds. Upon completion of construction, the contractor shall be held responsible to restore any haul roads, access roads, or staging areas that are outside of approved grading limits. This restoration shall be done in consultation with the project biologist. 4.3-5 Any landscaping plan(s) associated with the project shall be reviewed by a qualified biologist or resource specialist, who shall recommend appropriate provisions to prevent invasive plant species from colonizing in natural areas. These provisions may include the following: (a) Lyons Avenue/Dockweiler Drive Extension Project 4.3 Biological Resources SCH No. 2013082016 Page 4.3-23 City of Santa Clarita August 2017 review and screening of proposed plant palette and planting plans to identify and avoid the use of invasive species; (b) weed removal during the initial planting of landscaped areas; and (c) the monitoring for and removal of weeds and other invasive plant species as part of ongoing landscape maintenance activities. 4.3-6 All street lighting shall be downcast luminaries or directional lighting with light patterns directed away from natural areas. 4.3-7 Prior to issuance of a grading permit, an Oak tree report shall be prepared and approved. All oaks that will not be removed that are regulated under the City of Santa Clarita's Oak Tree Preservation and Protection Guidelines with driplines within 50 feet of land clearing (including brush clearing) or areas to be graded shall be enclosed in a temporary fenced zone for the duration of the clearing or grading activities. Fencing shall extend to the root protection zone (i.e., the area at least 15 feet from the trunk or 5 feet beyond the drip line, whichever distance is greater). No parking or storage of equipment, solvents, or chemicals that could adversely affect the trees shall be allowed within 25 feet of the trunk at any time. Removal of the fence shall occur only after the project arborist or qualified biologist confirms the health of preserved trees. 4.3.6 LEVEL OF SIGNIFICANCE AFTER MITIGATION With the incorporation of mitigation measures, impacts upon biological resources, including vegetation and wildlife resources would be less than significant.

CULTURAL RESOURCES 4.4.1 INTRODUCTION The following section addresses the proposed Project's potential to result in significant impacts upon cultural resources, including archaeological, paleontological and historic resources. On September 20, 2013, the South Central Coastal Information Center (SCCIC) and the Vertebrate Paleontology Department at the Natural History Museum of Los Angeles County were contacted to conduct a records search for cultural resources within the Project Site at the intersection of Lyons Avenue and Railroad Avenue and extends eastward towards the General Plan alignment for Dockweiler Drive towards The Master's University and northwest towards the intersection of 12'h Street and Arch Street and immediate Project vicinity. The analysis presented below is based on the record search results provided from the SCCIC, dated October 2, 2013, and written correspondence from The Vertebrate Paleontology Department at the Natural History Museum of Los Angeles County, dated October 18, 2013. Correspondences from both agencies are included in Appendix E to this Draft EIR. 4.4.2 ENVIRONMENTAL SETTING Description of the Study Area The Project Site is located at the intersection of Lyons Avenue and Railroad Avenue and extends eastward towards the General Plan alignment for Dockweiler Drive towards The Master's University and northwest towards the intersection of 12'h Street and Arch Street. The Project Site also includes the closure of an at - grade crossing at the intersection of Railroad Avenue and 13'h Street. The portion of the Project Site that extends eastward towards the General Plan alignment for Dockweiler Drive towards The Master's University is located in an area of primarily undeveloped land within the city limits of Santa Clarita. The vicinity consists of the single-family residential community of Placerita Canyon and The Masters University campus to the northeast, and the Newhall community (e.g. Old Town Newhall) including commercial and residential land uses to the west. The Project Site encompasses Newhall Creek which flows through the Project Site from northwest to southeast. The Project Site also encompasses a section of the active railroad tracks owned by the Southern California Regional Rail Authority (SCRRA) and the Union Pacific Railroad (UPRR). The SCRRA/UPRR rail tracks run parallel to Railroad Avenue and are perpendicular to Lyons Avenue. As discussed in the Downtown Newhall Historic Survey and Specific Plan Impact Analysis, "the buildings in the Downtown Newhall Specific Plan area lack the historic coherence and architectural cohesion necessary to form a historic district."' The City of Santa Clarita General Plan and the One Valley One Vision Plan, acknowledges that the City of Santa Clarita is working to maintain the remaining character within Old Town Newhall and many buildings are City Points of Historical Interest. 1 Palmer, Christine, Downtown Newhall Historic Survey And Specific Plan Impact Analysis, (2005) at page]]. Lyons Avenue/Dockweiler Drive Extension Project 4.4 Cultural Resources SCH No. 2013082016 Page 4.4-1 City of Santa Clarita August 2017 Paleontological Conditions Surficial deposits in most of the portion of the Project Site that extends eastward towards the General Plan alignment for Dockweiler Drive towards The Master's University consists of younger Quaternary gravels and sands associated with Newhall Creek that borders on the south and west and the Placerita Creek that flows through the Project Area. Both of these drainages flow into the Santa Clara River just to the northwest of the Proposed Project area. Generally, significant vertebrate fossils are not contained in such recent deposits. However, it is possible that fossils may have been carried to the Project Site area from surrounding hillsides and further upstream. The older deposits to the north of the Project Site may contain fossils. In the more elevated terrain in the southeastern portion of the Proposed Project area there are dissected older Quaternary fluvial and fan deposits as well as exposures of the terrestrial Pliocene Saugus Formation. These deposits may also occur at depth in the Proposed Project area. There are no fossil vertebrate localities nearby from the younger Quaternary alluvial deposits. The closest vertebrate fossil localities documented are from the Saugus Formation, or possibly the older Quaternary sediments, which are directly north of the Proposed Project. The fossils recorded were of a camel, Camelidae, and a horse Equus (LACM 6803-6804). Archaeological and Cultural Conditions No archaeological sites were identified on the portion of the Project Site that extends eastward towards the General Plan alignment for Dockweiler Drive towards The Master's University or within a '/2-mile radius of the Project Site. Two isolates were identified within a'/2-mile radius of the Project Site, and no isolates are identified within the Project Site. An isolate is an artifact found occurring by itself and is not indicative of an archaeological site. Fourteen historic structures were identified on SCCIC maps within a '/2-mile radius of the Project Site and no historic structures were identified within the Project Site. The California Point of Historical Interest (SPHI) and California Historical Landmarks (SHL), both within the Office of Historic Preservation within the Department of Parks and Recreation, list no historical structures or landmarks within the Project search radius or within the Project Site boundaries. Additionally, the California Register of Historical Resources (CAL REG) and the National Register of Historical Places (NRHP) list no properties within the Project search radius or within the Project Site boundaries. A list of the historical structures identified within the Project search radius can be found with the SCCIC response letter in Appendix E. Historic Setting There is little documentation about the specific cultural history of the Project area, including the ethnographic history of the native groups. The Tataviam tribe began occupying the Santa Clara River Valley around A.D. 450 and primarily lived in the upper reaches of the Santa Clara River and northward to the southern part of Antelope Valley and the San Gabriel Mountains. The Tataviam tribe was Uto- Lyons Avenue/Dockweiler Drive Extension Project 4.4 Cultural Resources SCH No. 2013082016 Page 4.4-2 City of Santa Clarita August 2017 Aztecan speakers of Shoshonean descent .2 Prior to the Tataviam habitation in the Santa Clara River Valley, archaeological discoveries suggest that humans may have occupied the entire Los Angeles region in excess of 20,000 years.3 Archaeological studies indicate that the Tataviam have similar patterns and ritual practices to the neighboring Chumash and Gabrielino/Tongva groups. The Gabrielino/Tongva were generally located to the south and the Chumash were generally located to the east of the Tataviam. Tataviam village sites with known names were located at San Francisquito, Piru, Camulos, Castaic Reservoir, Piru Creek, Elizabeth Lake, and in the Newhall environs .4 The three societies were primarily hunter and gatherer societies and hunted small game and lived in small villages and camps around water sources. The hunter and gatherer groups depended on stone tools and baskets .s Seasonal settlements and resource exploration have also been found along the Santa Clara River and Vasquez Rocks, and along natural springs and creeks that drain into the Santa Clara River. Bowers Cave near Val Verde, California (northwest of the Project Site) is of extreme cultural significance. Bowers Cave, discovered in 1884, yielded "one of the most significant assemblages of American Indian religious and ceremonial artifacts ever found in North America." Spanish explorer, Pedro Fages, first encountered the Tataviam in 1776.E In 1769, Gaspar de Portola led an expedition from San Diego to Monterey and documented the Santa Clarita region. The expedition passed north through the San Fernando Valley to Newhall and the Castaic Junction area. Then the expedition headed west, following the Santa Clara River, to San Buenaventura and travelled north to Monterey. The trail became know as "El Camino Viejo' (The Old Road). In 1797, the Mission San Fernando used much of Santa Clarita Valley for ranching and became known as the "Estancia de San Francisco Xavier." The native tribes of the area were displaced from their lands and were relocated on Mission grounds. The native tribes were baptized and forced to work. The Tataviam workers constructed the Estancia buildings near the confluence of Castaic Creek and the Santa Clara River. Today, the buildings no longer exist, but the area is still a protected site and is considered archaeologically rich. The Mexican Revolution in the 1820-1830s secularized the missions in California; and in 1839, Mexican army officer Ignacio del Valle was granted the Rancho San Francisco (comprising roughly 48,000 acres). The land encompasses Newhall and Placerita Creeks. Henry M. Newhall later purchased Rancho San Francisco in 1875. 2 Santa Clarita Valley Area Plan — One Valley, One Vision, Chapter 4: Conservation and Open Space Element, 2012. 3 Starzak, Richard, Historic Properties Survey Roort for the Proposed Alameda Corridor from the Ports ofLong Beach and Los Angeles to Downtown Los Angeles, in Los Angeles County.

Lyons Avenue/Dockweiler Drive Extension Project 4.4 Cultural Resources SCH No. 2013082016 Page 4.4-3 City of Santa Clarita August 2017 The first documentation of gold discovery in California occurred in Placerita Canyon in 1842, and nearly 1,300 pounds of gold were retrieved between 1842-1847. The discovery of gold prompted the development of mining camps and settlements throughout the mineral -rich Santa Clarita Valley. At the same time, in 1847, American explorer John C. Fremont arrived in Castaic Junction with his Buckskin Battalion, and he accepted the surrender of California from General Andres Pico. Fremont's crossing point through the Santa Susana Mountains became known as Fremont Pass, and was later renamed as Newhall Pass. In 1854, Fremont Pass was later expanded to allow for stagecoach access and provided a major route from St. Louis to San Francisco throughout the late 1850s. Oil seeps were discovered in Pico Canyon in 1865, and the area became the first location to be drilled for oil. Soon after Henry M. Newhall purchased Mission of San Francisco land, he opened the land up for the development of the Transcontinental Railroad. This, along with the development of Pico oil field and construction of the Pioneer Oil Refinery in the mid-1870s, prompted an oil boom in the Santa Clarita Valley. Additionally, with the completion of the railroad in the area in 1876, the town of Newhall began forming. From 1875-forward, much of the Valley's history can be tied to Newhall and his heirs.' Henry Newhall died in 1882, and his heirs formed The Newhall Land and Farming Company. Between 1936 through the mid-1950s, the Newhall Ranch underwent a radical change when Atholl McBean, grandson -in-law of Henry Newhall, struck oil. In the late 1950s, McBean shifted the Newhall Ranch into the land -development sector due to the housing patterns occurring in Southern California after World War II. During this transition from open land to master -planned community, the modern district of Newhall within the City of Santa Clarita has a number of historic properties within "Old Town Newhall" (west of the Project Site).8 Adding to the rich history of the Santa Clarita Valley, the Valley was commonly used as the setting for many western films during the 1930s and 1940s. Some of these western relics can be found in downtown Newhall, such as the Tom Mix Cottages. Regulatory Setting Historic resources fall within the jurisdiction of several levels of government. Federal laws provide the framework for the identification, and in certain instances, protection of historic resources. Additionally, states and local jurisdictions play active roles in the identification, documentation, and protection of such resources within their communities. The National Historic Preservation Act (NHPA) of 1966, as amended, and the California Register of Historical Resources (California Register) are the primary federal and state laws and regulations governing the evaluation and significance of historic resources of national, state, regional, and local importance. As archaeological resources are also considered historic, regulations applicable to historic resources are also applicable to archaeological resources and are discussed and analyzed in this section. Descriptions of these relevant laws and regulations are presented below. 7 Santa Clarita Valley Area Plan — One Valley, One Vision, Chapter 4: Conservation and Open Space Element, 2012. 8 Lyons Avenue At -Grade Rail Crossing, Impact Science, Inc. Draft EIR, March 2010. Lyons Avenue/Dockweiler Drive Extension Project 4.4 Cultural Resources SCH No. 2013082016 Page 4.4-4 City of Santa Clarita August 2017 Federal Regulations National Register of Historic Places The National Register of Historic Places (National Register) was established by the NHPA, as "an authoritative guide to be used by Federal, State, and local governments, private groups and citizens to identify the Nation's cultural resources and to indicate what properties should be considered for protection from destruction or impairment."9 The National Register recognizes properties that are significant at the national, state, and/or local levels. (i) Criteria To be eligible for listing in the National Register, a property must be at least 50 years of age (unless the property is of "exceptional importance") and possess significance in American history and culture, architecture, or archaeology. A property of potential significance must meet one or more of the following four established criteria:10 a) Associated with events that have made a significant contribution to the broad patterns of our history; or b) Associated with the lives of persons significant in our past; or c) Embody the distinctive characteristics of a type, period, or method of construction or that represent the work of a master, or that possess high artistic values, or that represent a significant and distinguishable entity whose components may lack individual distinction; or d) Yield, or may be likely to yield, information important in prehistory or history. (ii) Integrity According to National Register Bulletin #15, "to be listed in the National Register of Historic Places, a property must not only be shown to be significant under National Register criteria, but it also must have integrity." Integrity is defined in National Register Bulletin #15 as "the ability of a property to convey its significance."" Within the concept of integrity, the National Register recognizes the following seven aspects or qualities that in various combinations define integrity: feeling, association, workmanship, location, design, setting, and materials. (iii) Context To be eligible for listing in the National Register, a property must also be significant within a historic context. National Register Bulletin #15 states that the significance of a historic property can be judged only when it is evaluated within its historic context. Historic contexts are "those patterns or trends in history by which a specific occurrence, property, or site is understood and its meaning... within history or 9 36 Code of Federal Regulations (CFR) Section 60.2. 10 Title 36 Code ofFederal Regulations, Part 60.4 (2011). 11 National Register Bulletin #15, pp 44. (revised 2002). Lyons Avenue/Dockweiler Drive Extension Project 4.4 Cultural Resources SCH No. 2013082016 Page 4.4-5 City of Santa Clarita August 2017 prehistory is made clear." 12 A property must represent an important aspect of the area's history or prehistory and possess the requisite integrity to qualify for the National Register. (iv) Historic Districts The National Register includes significant properties, which are classified as buildings, sites, districts, structures, or objects. A historic district "derives its importance from being a unified entity, even though it is often composed of a wide variety of resources. The identity of a district results from the interrelationship of its resources, which can... be an arrangement of historically or functionally related properties."13 A district is defined as a geographically definable area of land containing a significant concentration of buildings, sites, structures, or objects united by past events or aesthetically by plan or physical development.14 A district's significance and historic integrity should help determine the boundaries. Other factors include: • Visual barriers that mark a change in the historic character of the area or that break the continuity of the district, such as new construction, highways, or development of a different character; • Visual changes in the character of the area due to different architectural styles, types, or periods, or to a decline in the concentration of contributing resources; • Boundaries at a specific time in history, such as the original city limits or the legally recorded boundaries of a housing subdivision, estate, or ranch; and • Clearly differentiated patterns of historical development, such as commercial versus residential or industrial. 15 Within historic districts, properties are identified as contributing and noncontributing. A contributing building, site, structure, or object adds to the historic associations, historic architectural qualities, or archeological values for which a district is significant because: • It was present during the period of significance, relates to the significance of the district, and retains its historical integrity or is capable of yielding importation information about the period; or • It independently meets the criterion for listing in the National Register. 16 Archaeological Resources The federal Archaeological Resources Protection Act of 1979 (Public Law 96-95) protects archaeological resources and sites on federal and Indian lands, including requirements for issuance of permits by federal land managers to excavate or remove archaeological resources.

Paleontological Resources In 2009, the Paleontological Resources Preservation Act (PRPA) became law when President Barack Obama signed the Omnibus Public Land Management Act (OPLMA) of 2009, Public Law I I1-011.17 The PRPA requires the Secretaries of the Interior and Agriculture to manage and protect paleontological resources on Federal land using scientific principles and expertise. The PRPA includes specific provisions addressing management of these resources by Federal agencies. It provides authority for the protection of paleontological resources on Federal lands including criminal and civil penalties for fossil theft and vandalism. The PRPA only applies to Federal lands and does not affect private lands. State Regulations California Register of Historical Resources In 1992, Governor Wilson signed Assembly Bill 2881 into law establishing the California Register of Historical Resources. The California Register is an authoritative guide used by state and local agencies, private groups, and citizens to identify historic resources and to indicate what properties are to be protected, to the extent prudent and feasible, from substantial adverse impacts.'$ The California Register consists of properties that are listed automatically as well as those that must be nominated through an application and public hearing process. The California Register automatically includes the following: • California properties listed in the National Register and those formally Determined Eligible for the National Register; • State Historical Landmarks from No. 0770 onward; and • Those California Points of Historical Interest that have been evaluated by the State Office of Historic Preservation (SOHP) and have been recommended to the State Historical Resources Commission for inclusion on the California Register.19 The criteria for eligibility of listing in the California Register are based upon National Register criteria, but are identified as 1-4 instead of A-D. To be eligible for listing in the California Register, a property generally must be at least 50 years of age and must possess significance at the local, state, or national level, under one or more of the following four criteria: 1. It is associated with events that have made a significant contribution to the broad patterns of local or regional history, or the cultural heritage of California or the United States; or 2. It is associated with the lives of persons important to local, California, or national history; or 3. It embodies the distinctive characteristics of a type, period, or method of construction or represents the work of a master, or possesses high artistic values; or 17 P.L. 111-011, Title VI, Subtitle D on Paleontological Resources Preservation (known by its popular name, the PRPA) (123 Stat. 1172; 16 U.S. C. 470aaa). 18 Public Resources Code Section 5024. ](a). 19 Public Resources Code Section 5024.1(d).

It has yielded, or has the potential to yield, information important in the prehistory or history of the local area, California, or the nation. Historic resources eligible for listing in the California Register may include buildings, sites, structures, objects, and historic districts. Resources less than 50 years of age may be eligible if it can be demonstrated that sufficient time has passed to understand its historical importance. While the enabling legislation for the California Register is less rigorous with regard to the issue of integrity, there is the expectation that properties reflect their appearance during their period of significance.20 The California Register may also include properties identified during historic resource surveys. However, the survey must meet all of the following criteria:21 1. The survey has been or will be included in the State Historic Resources Inventory; 2. The survey and the survey documentation were prepared in accordance with office [OHP] procedures and requirements; 3. The resource is evaluated and determined by the office [OHP] to have a significance rating of Category 1 to 5 on a DPR Form 523; and 4. If the survey is five or more years old at the time of its nomination for inclusion in the California Register, the survey is updated to identify historical resources which have become eligible or ineligible due to changed circumstances or further documentation and those which have been demolished or altered in a manner that substantially diminishes the significance of the resource. California Office ofHistoric Preservation Survey Methodology The evaluation instructions and classification system prescribed by the OHP in its Instructions for Recording Historical Resources provide a three -digit evaluation rating code for use in classifying potential historic resources. In 2003, the codes were revised to address the California Register. The first digit indicates the general category of evaluation. The second digit is a letter code to indicate whether the resource is separately eligible (S), eligible as part of a district (D), or both (B). The third digit is a number, which is coded to describe some of the circumstances or conditions of the evaluation. The general evaluation categories are as follows: 1. Listed in the National Register or the California Register. 2. Determined eligible for listing in the National Register or the California Register. 3. Appears eligible for listing in the National Register or the California Register through survey evaluation. 4. Appears eligible for listing in the National Register or the California Register through other evaluation. 5. Recognized as historically significant by local government. 6. Not eligible for listing or designation as specified. 7. Not evaluated or needs re-evaluation. 20 Public Resources Code Section 4852. 21 Public Resources Code Section 5024.1(g). Lyons Avenue/Dockweiler Drive Extension Project 4.4 Cultural Resources SCH No. 2013082016 Page 4.4-8 City of Santa Clarita August 2017 Native American Tribal Consultation In 2014 the California legislature added new requirements for tribal cultural resources through the approval of Assembly Bill (AB) 52. Pursuant to the provisions of AB 52, Public Resources Code (P.R.C.) Section 21084.2 establishes that "[a] project with an effect that may cause a substantial adverse change in the significance of a tribal cultural resource is a project that may have a significant effect on the environment." To help determine whether a project may have such an effect, CEQA requires a lead agency to consult with any California Native American tribe that requests consultation and is traditionally and culturally affiliated with the geographic area of a proposed project. Specifically, P.R.C. Section 21080.3.1(b) states: "Prior to the release of a negative declaration, mitigated negative declaration, or environmental impact report for a project, the lead agency shall begin consultation with a California Native American tribe that is traditionally and culturally affiliated with the geographic area of the proposed project if.• (1) the California Native American tribe requested to the lead agency, in writing, to be informed by the lead agency through formal notification of proposed projects in the geographic area that is traditionally and culturally affiliated with the tribe, and (2) the California Native American tribe responds, in writing, within 30 days of receipt of the formal notification, and requests the consultation. " The tribal notification requirements of AB 52 and P.R.C. Section 21080.3.1 became effective on July 1, 2015, and after the release of the Notice of Preparation (NOP) for this project.22 To date, no California Native American tribes have requested in writing to be informed by the lead agency through formal notification or have otherwise requested consultation. A copy of the NOP was submitted to the Native American Heritage Commission (NAHC) (see Appendix B to this EIR for a copy of the NAHC comment letter on the NOP). As recommended by the NAHC, provisions for the identification and evaluation of accidentally discovered archaeological resources have been incorporated into this EIR (See the Archaeological Resources and Tribal Cultural Resources subheadings below). Local Regulations City of Santa Clarita General Plan Chapter 2 of the General Plan, Land Use Element, addresses the objectives and policies to guide land uses within the City of Santa Clarita. Specifically, Objective LU 2.2 protects significant community resources from encroachment by incompatible uses, where feasible and appropriate. To achieve this objective, Policy LU 2.2.2 identifies sites and areas of cultural and historical value to the community, and ensure that uses in or adjacent to these areas will not impact their historical integrity. Additionally, Goal LU 6 aims to protect the community history and natural setting through building a scenic and beautiful urban environment. Objective LU 6.4 protects the Santa Clarita Valley's historical and cultural resources in a scenic setting through appropriate land use designations. The policies to achieve this goal and objective include: maintaining the historic buildings in Newhall through 22 The NOP was published on August 5, 2013. Lyons Avenue/Dockweiler Drive Extension Project 4.4 Cultural Resources SCH No. 2013082016 Page 4.4-9 City of Santa Clarita August 2017 implementation of preservation measures in the Downtown Newhall Specific Plan; enhancing the area around historic Land Station; maintain cultural resources from pre -historical Native American habitation and historical settlement in the identified areas around Santa Clarita, including along the Santa Clara River; and maintain the historic area of the Rancho San Francisco Estancia. Chapter 6 of the General Plan, Conservation and Open Space Element, addresses the objectives and policies to preserve open space. Goal CO 10 states that the preservation of open space is to meet the multiple objects for resource preservation. Objective CO 10.1 states that areas throughout the Santa Clarita Valley are to be identified and preserved as open space in order to conserve significant resources for long-term community benefit. To accomplish this goal and objective, Policy CO 10.1.4 aims to maintain and acquire, where appropriate, open space to preserve cultural and historic resources. It should be noted that the General Plan does not indicate any specific policies or goals with respect to preserving paleontological resources. One Valley One Vision General Plan Chapter 15, Goals, Objectives, and Policies, of the One Valley One Vision General Plan for the City of Santa Clarita addresses the objectives and policies to help implement the various goals. Goal CO-5 is to protect the historical and culturally significant resources that contribute to community identity and a sense of history. Objective CO-5.2 is to protect and enhance the historic character of Downtown Newhall. To achieve this goal and objective, the City of Santa Clarita requires that the City supports the Downtown Specific Plan policies to ensure that the character of new development is compatible with and does not detract from the context of historic buildings and block patterns; ensures that all aspects of community design in Newhall are of appropriate for this historic character of the district; and supports the diverse historical resources that illustrate the various phases of settlement within the Santa Clarita Valley. Objective CO-5.3 aims to encourage conservation and preservation of Native American cultural places, including prehistoric, archaeological, cultural, spiritual, and ceremonial sites on both public and private lands, throughout all stages of the planning and development process. To achieve this objective, the City of Santa Clarita requires that all proposed development projects that may have a potential impact on Native American cultural resources, provide notification to California Native American tribes, and consider the input received prior to a discretionary decision; and the City requires that studies be conducted on cultural resources for any new grading and development in areas identified as having a high potential for Native Americans resources, and incorporate recommendations to mitigate impacts. These goals and objects are also included in the Santa Clarita General Plan, Conservation Element. Downtown Newhall Specific Plan Although, the Project Site is not physically located in the Downtown Newhall Specific Plan study area, all fourteen historic structures identified by the SCCIC search are located in the Newhall Specific Plan study area. The Specific Plan states that it is important to preserve the historic resources downtown Newhall to provide value and appeal. This includes the restoration and the preservation of culturally significant Lyons Avenue/Dockweiler Drive Extension Project 4.4 Cultural Resources SCH No. 2013082016 Page 4.4-10 City of Santa Clarita August 2017 buildings. The Downtown Newhall Specific Plan asks that temporary fencing may be necessary to protect archaeological or historic resources during site preparation and construction. Historic Resources Study Area History of the Study Area For purposes of this analysis, the Project Site and surrounding Add Area properties were identified for evaluation using the City of Santa Clarita General Plan, Conservation and Open Space Element Historical Resources map and supplemented with additional historical properties identified by SCCIC. The Historic Resources Study Area is identified in Figure 4.4-1, below. The following presents an overview of the history of development within the study area. 4.4.3 ENVIRONMENTAL IMPACTS Methodology The historic resources assessment of the Lyons Avenue / Dockweiler Extension Project involved a multi- step methodology. In conducting the analysis of potential historic resources, SCCIC performed the following tasks: 1. Established the study area for the report as a larger area than the actual portion of the Project Site that extends eastward towards the General Plan alignment for Dockweiler Drive towards The Master's University. A '/2-mile radius was established as the study area for the archaeological and cultural search. 2. Reviewed the SCCIC database and maps for historic built -environment resources and archeological resources. Reviewed the California Historic Resources Inventory (HRI), the California Point of Historical Interest (SPHI), the California Historical landmarks (SHL), the California Register of Historical Resources (CAL REG), and the National Register of Historical Places (NRHP) for historical structures within the Project Site boundary and within the '/2-mile radius. No historical structures were identified within the Project Site. The HRI found 31 properties that have been evaluated for historical significance within a '/2—mile radius of the Project Site. Evaluation of a structure does not independently qualify the structure as historical. 3. Reviewed historic map of Santa Susana, California. The map indicates that in 1903, there was a significant amount of development with the Project Site. The Project Site was located within a dense urban environment with numerous roads and buildings. By 1941, the Project Site was still located within a dense urban environment with several roads and buildings. 4. Identified previous Cultural Resources investigations that were conducted within a '/2-mile radius of the Project Site. Twenty-four studies were identified within the '/2-mile radius of the Project Site, and eight studies are located within the Project Site.

Provides recommendations to minimize potential Project impacts to cultural and archeological resources. The Vertebrate Paleontology Department at the Natural History Museum of Los Angeles County conducted a Vertebrate Paleontology records search of the Natural History Museum of Los Angeles County for any fossils vertebrate localities that lie directly within the Project boundaries and the surrounding area for the portion of the Project Site that extends eastward towards the General Plan alignment for Dockweiler Drive towards The Master's University. No vertebrate fossil localities were identified within the Project Site. Two vertebrate fossil localities from the Saugus Formation (or possibly the older Quaternary sediments), directly north of the Project Site, produced fossil specimens of a camel (Camelidae) and horse (Equus). The Vertebrate Paleontology Department further provides recommendations to minimize potential Project impacts to paleontological resources. CEQA Guidelines Thresholds of Significance According to Checklist Questions V(a) through V(d) in Appendix G of the State CEQA Guidelines, a project may have a significant environmental impact if it were to: • Cause a substantial adverse change in significance of a historical resource as defined in § 15064.5; • Cause a substantial adverse change in significance of an archaeological resource pursuant to § 15064.5; • Directly or indirectly destroy a unique paleontological resource or site or unique geologic feature; or • Disturb any human remains, including those interred outside of formal cemeteries; The State Legislature has amended CEQA to clarify which properties are significant, as well as which project impacts are considered to be significantly adverse. A project with an effect that may cause a substantial adverse change in the significance of a historic resource is a project that may have a significant effect on the environment.23 A substantial adverse change in the significance of a historic resource means demolition, destruction, relocation, or alteration of the resource or its immediate surroundings such that the significance of an historical resource would be materially impaired.2a The Guidelines further provide that "the significance of an historic resource is materially impaired when a project... demolishes or materially alters in an adverse manner those physical characteristics of an historical resource that convey its historical significance and that justify its inclusion in, or eligibility for, inclusion in the California Register of Historical Resources... local register of historic resources... or its identification in a historic resources survey. ,25 Additionally, in accordance with the amended CEQA Guidelines adopted in response to AB 52, a project 23 CEQA Guidelines, Section 15064.5(b). 24 CEQA Guidelines, Section 15064.5(b)(1). 25 CEQA Guidelines, Section 15064.5(b)(2). Lyons Avenue/Dockweiler Drive Extension Project 4.4 Cultural Resources SCH No. 2013082016 Page 4.4-13 City of Santa Clarita August 2017 may have a significant environmental impact if it would cause a substantial adverse change in the significance of a tribal cultural resource, defined in P.R.0 Section 21074 as either a site, feature, place, cultural landscape that is geographically defined in terms of the size and scope of the landscape, sacred place, or object with cultural value to a California Native American tribe, and that is: (a) Listed or eligible for listing in the California Register of Historical Resources, or in a local register of historical resources as defined in P.R.C. Section 5020.1(k); or (b) A resource determined by the lead agency, in its discretion and supported by substantial evidence, to be significant pursuant to criteria set forth in subdivision (c) of P.R.C. Section 5024.1. In applying the criteria set forth in subdivision (c) of P.R.C. Section 5024.1, the lead agency shall consider the significance of the resource to a California Native American tribe. Project Impacts Cultural and Historic Resources A project that may cause a substantial adverse change in the significance of a historical resource is a project that may have a significant effect on the environment. There are no habitable structures located within the Project Site. The Project Site includes the roadway extension and widening of the intersection of Lyons Avenue and Railroad Avenue and extends eastward towards the General Plan alignment for Dockweiler Drive towards The Master's University and northwest towards the intersection of 12"' Street and Arch Street, the closure of an at -grade crossing at the intersection of Railroad Avenue and 13a' Street. The portion of the Project Site located at the intersection of Lyons Avenue and Railroad Avenue that extends eastward towards the General Plan alignment for Dockweiler Drive towards The Master's University and northwest towards the intersection of 12a' Street and Arch Street would have the potential to adversely impact historic or cultural resources as it includes improving roadway segments and a road extension over undeveloped open space area. Archaeological Resources Section 15064.5 of the State CEQA Guidelines defines significant archaeological resources as resources that meet the criteria for historical resources, as described above, or resources that constitute unique archaeological resources. A project -related significant impact may occur if the Proposed Project were to affect archaeological resources. Moreover, a significant impact may occur if project activities, such as grading or excavation, were to disturb previously untouched archeological resources or Native American burial sites. No known archeological sites are identified within the Project Site. While, portions of the Project Site are improved with roadways, the Proposed Project will consist of earthwork activities, such as grading and excavation, in areas that are currently undeveloped. Construction -related earthwork activities may result in the accidental discovery of prehistoric or historic archaeological resources or Native American burial sites. In the unlikely event archaeological resources are discovered during excavation, grading, or construction activities, work will be halted in the area of the find until a qualified archaeologist has evaluated the find in accordance with federal, State, and local guidelines, including Lyons Avenue/Dockweiler Drive Extension Project 4.4 Cultural Resources SCH No. 2013082016 Page 4.4-14 City of Santa Clarita August 2017 those set forth in California Public Resources Code Section 21083.2. State law prohibits the collection or disturbance of any suspected archaeological materials until a qualified archaeologist is contacted to survey the find. Construction activity may continue unimpeded on other portions of the Project site. The found deposits would be treated in accordance with federal, State, and local guidelines, including those set forth in California Public Resources Code Section 21083.2(i). Thus, with implementation of Mitigation Measure 4.4-1, impacts would be reduced to less than significant levels. Paleontological Resources A significant adverse effect could also occur if grading or excavation activities associated with the project were to disturb any paleontological remains within the Project Site. The records search conducted by the Vertebrate Paleontology Department of the Natural History Museum of Los Angeles County yielded no known fossil localities within the Project Site. The closest vertebrate fossil localities are from the Saugus Formation, located directly north of the Proposed Project Site. The fossil specimens are of a camel, Camelidae, and a horse, Eguus. While it is possible that fossilized materials may be discovered during site preparation and construction, specifically grading and excavation activities, precautionary measures set forth in Mitigation Measure 4.4-2 would reduce any potential adverse impacts to paleontological resources to a less than significant level. Tribal Cultural Resources As noted above, the NOP for the proposed project preceded AB 52 and the CEQA amendments pertaining to the public notification requirements of Native American Tribes. CEQA requires a lead agency to consult with any California Native American tribe that requests consultation and is traditionally and culturally affiliated with the geographic area of a proposed project. No California Native American tribes have requested in writing to be informed by the lead agency through formal notification or have otherwise requested consultation. Based on a records search conducted through the South Central Coastal Information Center (SCCIC) (see Appendix E to this EIR), no archaeological sites have been identified within a '/2-mile radius of the Project Site. As such, the Proposed Project would not have a direct impact upon known archaeological resources, including Native American tribal resources. However, as noted in the NAHC's response letter to the NOP, a lack of surface evidence of archeological resources does not preclude their subsurface existence. As such, provisions for the identification and evaluation of accidentally discovered archeological resources would be implemented in accordance with mitigation measure 4.4-1, below. With the incorporation of mitigation measure 4.4-1, impacts upon tribal resources would be less than significant. 4.4.4 CUMULATIVE IMPACTS In accordance with Section 15130(b)(1)(A)(B) of the CEQA Guidelines, an adequate discussion of a project's significant cumulative impact, in combination with other closely related projects, can be based on either: (1) a list of past, present, and probable future producing related impacts; or (2) a summary of projections contained in an adopted local, regional, or statewide plan or related planning document that describes conditions contributing to the cumulative effect. The lead agency may also blend the "list" and "plan" approaches to analyze the severity of impacts and their likelihood of occurrence. For purposes of Lyons Avenue/Dockweiler Drive Extension Project 4.4 Cultural Resources SCH No. 2013082016 Page 4.4-15 City of Santa Clarita August 2017 assessing the Project's cumulative impact with respect to impacts upon cultural resources (including archaeological, paleontological and historic resources), the analysis below is appropriately based on a combination of the plan -based approach and the list -based approach to determine the Project's contributing effect on potential cumulative impacts on cultural resources. The Proposed Project would result in the development of an undeveloped surrounding area, and provide improved access to The Masters University, Old Town Newhall, and the rural residential community of Placerita Canyon. However, impacts to cultural resources tend to be site -specific and are assessed on a site -by -site basis. Additionally, the historic resource assessment for the Proposed Project concluded that the Project will not result in significant adverse impacts on identified historic resources located within and adjacent to the Project Site following appropriate mitigation. Therefore, the Proposed Project's incremental contribution to a cumulative impact would not be considerable, and cumulative impacts to cultural resources would be less than significant. 4.4.5 MITIGATION MEASURES 4.4-1 In the event any archaeological materials are encountered during the course of Project development, all construction activity shall halt in the area of the find and the services of a qualified archaeologist shall be secured to assess the discovered material(s) and prepare a survey, study or report evaluating the significance of the materials encountered. The archaeologist's written assessment shall contain a detailed description of the materials encountered, and recommendations if necessary, for the preservation, conservation, or relocation of the resource. Project development activities may resume once copies of the archaeological survey, study or report are submitted to the satisfaction of the Planning Director and copies distributed to the SCCIC Department of Anthropology. 4.4-2 In the event any suspected paleontological materials are encountered during the course of Project development, all construction activity shall halt in the area of the find and the services of a qualified paleontologist shall be secured to assess the discovered material(s) and prepare a survey, study or report evaluating the significance of the materials encountered. The paleontologist's written assessment shall contain a detailed description of the materials encountered, and recommendations if necessary, for the preservation, conservation, or relocation of the resource. Project development activities may resume once copies of the paleontological survey, study or report are submitted to the satisfaction of the Planning Director and copies distributed to the Los Angeles County Natural History Museum. 4.4.6 LEVEL OF SIGNIFICANCE AFTER MITIGATION With the incorporation of mitigation measures, impacts upon cultural resources, including archaeological, paleontological, historic, and Native American Tribal resources would be less than significant.

GEOLOGY/SOILS 4.5.1 INTRODUCTION The following section of the Draft EIR evaluates potential impacts related to geology, including seismicity and soils associated with development of the Proposed Project. The majority of the analysis is based on the Geologic and Geotechnical Report EIR-Level Review Of Road Alignments For Dockweiler Road and Lyons Avenue (The "Geotechnical Report') prepared by Allan E. Seward Engineering Geology, Inc., dated October 17, 2014. The Geotechnical Report is included as Appendix F of this Draft EIR. 4.5.2 ENVIRONMENTAL SETTING The Project Site is generally located in the Old Town Newhall area of the City of Santa Clarita. The Project Site is located at the intersection of Lyons Avenue and Railroad Avenue and extends eastward towards the General Plan alignment for Dockweiler Drive towards The Master's University and northwest towards the intersection of 12'h Street and Arch Street. The Project Site also includes the closure of an at - grade crossing at the intersection of Railroad Avenue and 13'h Street and associated street modification improvements. With respect to the Geotechnical Report, and the analysis presented below, the Project Site is defined as the area that consists of future road alignments for extension of Lyons Avenue from its current northeastern terminus at Railroad Avenue to a future intersection with proposed Dockweiler Drive approximately 600 ft. to the northeast. This includes a proposed at -grade crossing over the existing Southern Pacific railroad tracks and a crossing over Newhall Creek using a box culvert to connect to the proposed extension of Dockweiler Drive. Dockweiler Drive is proposed to extend from a point of connection at the Master's University property boundary northwesterly for approximately 2,000 feet to the intersection of Arch Street and 13a' Street. Aden Avenue is to extend from its current southerly terminus to intersect with the future Dockweiler Drive approximately 250 ft. to the south (See Figure 4.5- 1, Geologic Overview Map). The proposed road alignments are located on the alluvial flood plain and hillside areas adjacent to Newhall Creek. The majority of the proposed road alignment for Lyons Avenue traverses undeveloped land, except for areas where artificial fill and railroad ballast have been placed to elevate and support the existing railroad double tracks. Dumped fill with abundant blocks of asphalt and concrete and other miscellaneous debris has been placed on the southwest bank of Newhall Creek, just northeast of the proposed at -grade railroad crossing. The proposed road alignment of Dockweiler Drive also traverses undeveloped land and a storage yard utilized by Los Angeles County Department of Public Works. The Project Site is covered with light to moderate growth of natural grasses and chaparral. Elevations at the site range from approximately 1255 to 1370 feet above mean sea level.

PARKER Figure 4.5-1 ENVIRONMENTAL CONSULTANTS Geological Overview Map City of Santa Clarita August 2017 Regional Geologic Conditions The Project Site is located within the central part of the Transverse Ranges geomorphic province of southern California, in the eastern portion of the Ventura Basin. The Ventura Basin has been tectonically down -warped in the geologic past to produce a large-scale synclinal structure in which a thick sequence of Cenozoic sediments has accumulated. In the vicinity of the proposed road alignments, much of the hillside area along the northeastern margin of Newhall Creek consists of bedrock of the Quaternary -age Pacoima Formation (Qp). The relatively flat flood plain southwest of Newhall Creek is underlain by sub - horizontal alluvium deposited (Qal). The Pacoima Formation and alluvial deposits are underlain by bedrock of the Plio-Pleistocene, nonmarine Saugus Formation (TQs). No faults or folds have been identified at the Project Site on the referenced published geologic map of the area. Figure 4.5-1 provides a Geologic Overview Map, which is based on the Geologic Map of the Newhall Quadrangle (Dibblee, 1996). Geological Structure The natural slopes at the Project Site are underlain by sub -horizontally bedded Pacoima Formation in erosional unconformable contact over Plio-Pleistocene non -marine sediments of the Saugus Formation. The Saugus Formation in the vicinity of the Project Site generally strikes roughly east to west and dips gently to the north (Treiman, 1987; and Dibble, 1996). The Saugus Formation bedding measured in northern bank of the Newhall Creek strikes N70W and dips 5° north. The measured bedding is generally consistent with regional geologic maps and the geologic structure as documented during a previous investigation and published report. Geologic Units As depicted in Figure 4.5-2, Geologic Map, Plate I, the approximate limits of exposed geologic units based on field observations and the referenced published geologic maps. Artificial fill and railroad ballast have been placed below the railroad tracks. Pavement and aggregate base have been placed beneath existing roadways. General descriptions of geologic units provided below are based the prior geologic observation in the vicinity of the Project Site, and the exposures in the banks of Newhall Creek in the vicinity of the proposed box culvert. Saugus Formation (TQs) Bedrock of the Plio-Pleistocene-age Saugus Formation (TQs) is exposed along the lower portion of the northerly eroded bank of Newhall Creek, just east of the proposed road alignment. The Saugus Formation sediments consist dominantly of gray to light brown sandstone and conglomeratic sandstone with scattered greenish -gray siltstone and silty sandstone (Treiman, 1987). Bedding within the Saugus Formation varies from predominately massive and indistinct to cross -bedded to locally well -developed planes on lensing, fine-grained units. Local variance in bedding orientations is common and is due to cross bedding and/or channelized (erosional) contacts.

This formation has been designated as "Older Dissected Surficial Sediments or Qog" after Dibblee, 1996; however, these terrace deposits have been assigned to the Pacoima Formation (of Oakeshott, 1958) by Treiman (CDMG, 1987). In the Geotechnical Report, the nomenclature by Treiman is used. The bedrock generally consists of lensing, crudely stratified, light yellowish -brown to yellowish -brown to brown, silty to clayey, fine- to coarse -grained sandstone with some gravel, cobbles and rare boulders. Bedding is generally crude to locally well defined. Generally the bedrock is concealed by a mantling of soil and colluvium. However, the eroded banks of the Newhall Creek expose unweathered bedrock. Quaternary Alluvium (Qal) Quaternary Alluvium (Qal) underlies the existing surficial artificial fill materials located westerly of Newhall Creek south of 12th Street, and easterly of Newhall Creek north of 12th Street. Based on data obtained by this firm for the adjacent Old Town Newhall Library site, the alluvium is anticipated to consist of interbedded layers of poorly graded sand, silty sand, and gravelly sand. Interbedded layers of sandy silts and clays may also be present. These materials are typically medium dense to dense in the upper 30 to 40 feet with locally loose conditions in the upper 10 feet. Recent Stream Channel Deposits (Qsc) Quaternary Stream channel deposits (Qsc) are located within the active Newhall Creek channel. These deposits consist of recent alluvium that has been reworked due to heavy runoff during periodic rains. Stream channel deposits are very similar to the Quaternary alluvium and generally consist of silty sands, sands, and gravels with cobbles. Quaternary Colluvium (Qc) Colluvium (Qc) is a non -bedded, heterogeneous accumulation of soil and weathered bedrock deposited by gravity on all but the steepest slopes. These deposits have been mapped based on review of the topography where the estimated thickness is greater than about 3 feet. Artificial Fill (afi Artificial fill (af) was apparently placed below the existing railroad tracks to elevate the tracks above the Newhall Creek Flood Plain. The engineering characteristics of this material are currently unknown. Dumped Fill (dfi Dumped fill (df) is present along the active stream margins of Newhall Creek at the vicinity of the proposed Lyons Avenue road alignment. The dumped fill consists of fill soils with abundant debris (asphalt, concrete, construction trash, metal, vehicle tires). Also present near the proposed alignment is an abandoned vehicle that is partially buried. Lyons Avenue/Dockweiler Drive Extension Project 4.5 Geology/Soils SCH No. 2013082016 Page 4.5-5 City of Santa Clarita August 2017 Railroad Ballast (rb) Railroad ballast (rb) consisting of crushed natural rock was placed to support and elevate the two sets of railroad tracks at the site. Landslides Review of the referenced published geologic maps indicates that no landslides have been mapped at or adjacent to the site. Review of aerial photographs lack geomorphic features that would indicate prior landslide movement. Ground Water Review of historic ground water data from the Seismic Hazard Map for the Newhall Quadrangle, Water - Resources Investigation using Analog Model Techniques in the Saugus -Newhall Area (Robson, 1972), and Los Angeles Flood Control District (LACFCD) water well records indicates that historic high ground water levels are between 75 and 100 feet below the existing surface at the Project Site. The locations of nearby water wells are shown in Figure 4.5-3, Water Well Location Map. The historic ground water levels for each well obtained from LACFCD records are provided in Table 4.5-1, Summary of LAFCD Water Well Data. In addition, ground water was not encountered in subsurface explorations performed by this firm to a depth of 50 ft in the alluvium for the adjacent Old Town Newhall Library. However, temporary perched ground water conditions may exist below Newhall Creek following periods of significant rainfall and runoff.

Perched ground water can contribute to slope instability in natural slopes and cut slopes. To prevent build-up of water, subdrains are typically recommended in canyon areas in which fill will be placed and back drains for slopes that are to be constructed as Stability Fills or Buttress Fills. Due to the historic high ground water elevations and the elevated nature of portions of the road alignment, ground water is not expected to significantly affect the project, provided the proposed grading is evaluated from a geotechnical standpoint during the design stage and the geoteclmical recommendations are implemented during construction. Seismic Considerations The Project Site lies within the seismically active southern California region. Earthquake -related hazards typically include ground rupture, ground shaking, and ground failure. Review of the Alquist-Priolo Earthquake Fault Zone Map for the Newhall Quadrangle, the Seismic Safety Element of the L.A. County General Plan, and the published Geologic Maps indicates that no active or potentially active faults traverse the Project Site. Review of the site topography and the aerial photographs did not reveal any lineaments or other indicators suggestive of faulting at the Project Site. The nearest known active fault is the San Gabriel. Fault, which is 3.7 km from the site at its nearest point. Table 4.5-2 provides a list of regional faults near the Project Site, Figure 4.5-4 provides a map of the fault locations. and Figure 4.5-5 provides a Seismic Hazards Map. Based on these distances, the probability of fault -related ground rupture at the site is considered to be very low.

The mapped MCE geometric mean (MCEG) peak ground accelerations (PGAM) adjusted for Site Class effects were first evaluated using the U.S. Seismic Design Maps web tool provided by the United States Geological Survey (USGS). The MCEG PGAM was then evaluated for a two percent probability of exceedance within a 50-year period using the USGS 2008 Interactive Deaggregation web tool. The PGAM calculated using the probabilistic procedure is based on estimated values of shear wave velocity (Voo) within the range designated for the corresponding Site Class. The estimated PGAM for bedrock (L 17g) and alluvial (1.03g) soil conditions was taken as the lesser of the mapped geometric mean pear ground accelerations and the probabilistic geometric mean peak ground accelerations indicated in the Table 4.5-3.

Seward Engineering Geology, Inc., October 2014. Ground Failure Ground failure is a general term for seismically induced, secondary, permanent ground deformation caused by strong ground motion. This includes liquefaction, lateral spreading, ground lurching, seismic settlement of poorly consolidated materials (dynamic densification), differential materials response, sympathetic movement on weak bedding planes or non -causative faults, slope failures, and shattered ridge effects. The majority of the Project Site is underlain by bedrock materials that are not susceptible to liquefaction. The alluvial soils present at the site, as depicted in Figure 4.5-2. are not designated on the State of California Seismic Hazard Zone Map for the Newhall Quadrangle as a zone in which investigation of potentially liquefiable materials is required. The depth to historic high ground water at the Project Site is greater than 50 feet. Based on the preceding factors, the potential for liquefaction and associated seismic settlements and lateral spreading is therefore considered very low. Relatively loose granular alluvial soils located within and adjacent to the active Newhall Creek channel and within minor tributary canyons adjacent to the road alignment may be prone to dynamic densification as a result of future earthquake shaking. Evaluation of the potential for dynamic densification should be performed at the design stage. Typically the potential for dynamic densification of these materials can be Lyons Avenue/Dock-weiler Drive Extension Project 4.5 Geology/Soils SCH No. 2013082016 Page 4.5-11 City of Santa Clarita August 2017 mitigated by removal of the materials and then replacing them as compacted fill. Potential for seismic settlement (dynamic densification) is negligible in the bedrock portions of the site. The hillside areas directly adjacent to the road alignment are designated on the State of California Seismic Hazard Zone Map for the Newhall Quadrangle as a zone in which investigation of potential for earthquake -induced landslides is required (see Figure 4.5-5). The potential for earthquake -induced slope failures and surficial failures on the critical natural and proposed design slopes will need to be evaluated at the design stage. Cut and fill slopes constructed per the California Building Code typically are not subject to earthquake -induced failures. Typical mitigation for slopes prone to earthquake -induced failures include avoidance, removal of surficially unstable materials, laying back the slope to a shallower gradient, buttressing, construction of shear keyways, or debris basins and walls that may be designed to divert and/or collect the calculated volume of material expected to fail. Additionally, no landslides have been mapped at the Project Site. Due to the relatively shallow dip of the bedding of the Pacoima Formation and the Saugus Formation bedrock, and of the flat -lying alluvial deposits that underlie the site, the potential for differential materials response and slippage along weak bedding planes is considered to be negligible. Slope Stability It is anticipated that both cut and fill slopes will be necessary at various locations along the proposed alignments and that cut slopes will expose Saugus Formation and Pacoima Formation bedrock. These proposed slopes should be designed and constructed at gradients of 2:1 horizontal to vertical or shallower. All constructed slopes should be evaluated by a geotechnical firm for conformance to applicable requirements/standards for gross and surficial slope stability. If it is determined that proposed slopes do not satisfy required factor of safety requirements for gross slope stability, mitigation measures will have to be designed based on results of slope stability analyses. If surficial stability of the proposed slopes is determined to be insufficient, measures to mitigate surficial stability will be required. This may include but not be limited to the following: 1. Avoidance 2. Stability fills 3. Flattening of slopes to 3:1 (h:v), or flatter 4. Seeding/planting of slopes 5. Guniting of slopes 6. Mechanically Stabilized Earth (MSE) slopes Natural slopes adjacent to the proposed road alignments exposing adverse geologic bedding conditions or steep gradients should be evaluated. If it is determined that these slopes do not satisfy required factor of safety requirements the natural slopes may be stabilized with Buttress Fills or Shear Keys designed by the Project Geotechnical Engineer. Laboratory testing fill source materials is required to evaluate both gross and surficial stability of the proposed fill slopes, including remedial Buttress Fills and Stability Fills. Shear strength testing should be performed on soil samples that represent the mixture of materials that will be placed in the proposed fills. Lyons Avenue/Dockweiler Drive Extension Project 4.5 Geology/Soils SCH No. 2013082016 Page 4.5-12 City of Santa Clarita August 2017 Steep natural slopes adjacent to the proposed road alignment should also be evaluated for potential debris flow hazards. Avoidance of the hazard by selective structural locations, construction of impact or debris walls and/or debris basins, control of run-off or removal of loose surficial materials can be used to mitigate debris flow hazards. Deep Fills Based on preliminary review of the proposed road alignments, deep fill areas (i.e. fills deeper than 40 ft below proposed grade) are not anticipated. Soil Compressibility Rapidly buried, unsaturated sediments, such as colluvium and alluvium, commonly contain extensive voids and, as a consequence, are subject to hydro -compression (collapse) settlement when inundated. Hydro -compression occurs when water enters sediments and reorients the sediment particles into a more compact arrangement with fewer and smaller voids. Compacted fills and structures constructed over deposits prone to hydro -compression may experience settlement and associated distress and damage. Based on explorations for the adjacent Old Town Newhall Library site, alluvial soils at the Project Site are anticipated to be typically medium dense to depths of 30 to 40 ft, with local loose zones in the upper 10 feet. The density of the artificial fill placed below the railroad tracks is currently undefined. The potential for settlement within these units should be addressed in more detail during a future geotechnical investigation at the design stage. If soils subject to hydro -compression or consolidation are identified at the Project Site, settlement and potential adverse impacts to the proposed road improvements can be mitigated by removal and recompaction of loose or soft material. The phenomenon of hydro -compression does not apply to the bedrock deposits that underlie most of the Project Site. Further exploration should be performed at the site to evaluate if hydro -compression -prone materials, such as colluvium, are present in areas where pavements or compacted fills are proposed. Erosion Potential and Drainage Fill, bedrock, and soil materials at the site will be susceptible to erosion if drainage features to control sheet flow over the ground surface are not provided. The drainage features should be designed to prevent water from ponding on graded areas and from flowing over natural or constructed slopes, and should direct surface water to designed debris basins or natural drainage courses, where applicable. Debris material generated by erosion of site materials should be contained inside the site boundaries. The potential for erosion of the banks of Newhall Creek should be evaluated by the project civil engineer. Dam Inundation and Flooding No dams currently exist in the Newhall Creek Drainage and the Project Site is not in a dam inundation area per the Flood and Inundation Hazard Map (Plate 6) of the Los Angeles County Safety Element of the Lyons Avenue/Dockweiler Drive Extension Project 4.5 Geology/Soils SCH No. 2013082016 Page 4.5-13 City of Santa Clarita August 2017 General Plan. The potential for dam inundation is therefore considered nonexistent. The potential for flooding of Newhall Creek is addressed in Section 4.6, Hydrology and Water Quality. Regulatory Framework Applicable State Regulations/Policies Alquist-Priolo Earthquake Fault Zoning Act California's Alquist-Priolo Act (Public Resources Code § 2621 et seq.), originally enacted in 1972 as the Alquist-Priolo Special Studies Zone Act and renamed in 1994, is intended to reduce the risk of life and property from surface fault rupture during earthquakes. The Alquist-Priolo Act prohibits the location of most types of structures intended for human occupancy across the traces of active faults and strictly regulates construction in the corridors along active faults (Earthquake Fault Zone). It also defines criteria for identifying active faults, giving legal weight to terms such as "active," and establishes a process for reviewing building proposals in and adjacent to Earthquake Fault Zones. Under the Alquist-Priolo Act, fault zones are defined, and construction along or across them is strictly regulated if they are "sufficiently active" and "well-defined." A fault is considered sufficiently active if one or more of its segments or strands shows evidence of surface displacement during Holocene time (defined for the purposes of the Act as within the last 11,000 years). A fault is considered well-defined if its trace can be clearly identified by a trained geologist at the ground surface or in the shallow subsurface, using standard professional techniques, criteria, and judgment. Seismic Hazards Mapping Act The Seismic Hazards Mapping Act of 1990 (Public Resources Code §§ 2690-2699.6) is intended to reduce the damage resulting from earthquakes. While the Alquist-Priolo Act addresses surface fault rupture, the Seismic Hazards Mapping Act addresses other earthquake -related hazards, including strong ground shaking, liquefaction, and seismically induced landslides. Its provisions are similar in concept to those of the Alquist-Priolo Act; the State is charged with identifying and mapping areas at risk of strong ground shaking, liquefaction, landslides, and other corollary hazards; and cities and counties are required to regulate development within mapped Seismic Hazard Zones. Under the Seismic Hazards Mapping Act, permit review is the primary mechanism for local regulation of development. Specifically cities and counties are prohibited from issuing development permits for sites in Seismic Hazard Zones until appropriate site -specific geologic or geotechnical investigations have been carried out, and measures to reduce potential damage have been incorporated into the development plans. California Building Standards Code The State of California's minimum standards for structural design and construction are given in the California Building Standards Code (CBSC) (California Code of Regulations Title 24). The CBSC is based on the IBC (International Code Council, 1997), which is used widely throughout the United States (generally adopted on a state -by -state or district -by -district basis) and has been modified for California Lyons Avenue/Dockweiler Drive Extension Project 4.5 Geology/Soils SCH No. 2013082016 Page 4.5-14 City of Santa Clarita August 2017 conditions with numerous, more detailed or more stringent regulations. The CBSC requires that "classification of the soil at each building site will be determined when required by the building official" and that "the classification will be based on observation and any necessary test of the materials disclosed by borings or excavations." In addition, the CBSC states that "the soil classification and design -bearing capacity will be shown in the building plans, unless the foundation conforms to specified requirements." The CBSC provides standards for various aspects of construction, including but not limited to: excavation, grading, and earthwork construction; fills and embankments; expansive soils; foundation investigations; and liquefaction potential and soil strength loss. In accordance with California law, the Project would be required to comply with all provisions of the CBSC. Applicable Local Regulations/Policies City of Santa Clarita Unified Development Code All grading and excavation activities are subject to comply with Chapters 17.20 to 17.30 (Division 3) of the City of Santa Clarita Unified Development Code (UDC). Rules and regulations contained within these chapters provide for the control of excavation, grading, and earthwork construction, including fills or embankment activities. During the grading permit application process, the City Engineer may require engineering geological and soil reports, as well as seismic hazard zone studies be prepared for proposed developments. The engineering geological report would require an adequate description of the geology of the site, along with conclusions and recommendations regarding the effect of geologic condition of any proposed development. Soil reports would be required to characterize the existing soil resources on a site, and provide recommendations for grading and design criteria. Development in seismic hazard zone will require studies that evaluate the potential for seismically induced liquefaction, soil instability, and earthquake induced landslides to occur on a site. The City of Santa Clarita enforces structural requirements of the building code, the Alquist-Priolo Special Studies Zones, and sound engineering and geotechnical practices in evaluating structural stability of proposed new development. 4.5.3 ENVIRONMENTAL IMPACTS Thresholds of Significance In accordance with guidance provided in the Environmental Checklist Form contained in Appendix G to the State CEQA Guidelines, lead agencies are encouraged to address the questions from the Checklist that are relevant to the Project's environmental effects. With respect to Geology and Soils, the following Checklist Questions are addressed under the Project Impacts/Environmental Consequences subheading below. Would the Project: (a) Expose people or structures to potential substantial adverse effects, including the risk of loss, injury, or death involving: i) Rupture of a known earthquake fault, as delineated on the most recent Alquist-Priolo Earthquake Fault Zoning Map issued by the State Geologist for the area or based on other substantial evidence of a known fault (Refer to Division of Mines and Geology Special Publication 42); Lyons Avenue/Dockweiler Drive Extension Project 4.5 Geology/Soils SCH No. 2013082016 Page 4.5-15 City of Santa Clarita August 2017 ii) Strong seismic ground shaking; iii) Seismic -related ground failure, including liquefaction; or iv) Landslides; (b) Result in substantial soil erosion or the loss of topsoil; (c) Be located on a geologic unit or soil that is unstable, or that would become unstable as a result of the project, and potentially result in on- or off -site landslide, lateral spreading, subsidence, liquefaction, or collapse; (d) Be located on expansive soil, as defined in Table 18-1-B of the Uniform Building Code (1994) creating substantial risks to life or property; or (e) Have soils incapable of adequately supporting the use of septic tanks or alternative waste water disposal systems where sewers are not available for disposal of waste water? As discussed in the Initial Study, the Proposed Project would have a potentially significant impact on Geology and Soils Checklist questions (a)-(d) and less than significant impact on Checklist question (e), reproduced above. Project Impacts Strong Seismic Ground Shaking Potential for primary ground rupture on a fault at the Project Site is considered to be low. Peak ground acceleration (PGA) consistent with maximum considered earthquake (MCE) ground motions is expected to be 1.03g in alluvial portions of the site and 1.10g in portions of the site where bedrock outcrops or is present at shallow depth. Therefore, with implementation of Mitigation Measure 4.5-1, impacts with respect to strong seismic ground shaking would be less that significant. Seismic -Related Ground Failure, Including Liquefaction The alluvium that underlies portions of the Project Site is not designated as potentially liquefiable on the State of California Seismic Hazard Zone Map for the Newhall Quadrangle. In addition, historic high ground water elevations are greater than 50 ft in depth. Therefore the potential for liquefaction of alluvium is considered very low. The potential for seismic settlement (dynamic densification) during future seismic events is non-existent in the bedrock portions for the Project Site but should be evaluated in site alluvial soils, colluvium, and existing artificial fills to remain in place. All slopes should be evaluated by the Project Geotechnical Engineer at the planning and design stages. The hillside area of the Project Site is designated on the State of California Seismic Hazard Zone Map to have earthquake -induced slope instability. However, the potential for earthquake -induced slope failures is considered low provided that future geologic and geotechnical evaluations and recommendations for slope stability is incorporated into design and construction. Therefore, with implementation of Mitigation Measure 4.5-1, impacts with respect to seismic -related ground failure would be less that significant. Lyons Avenue/Dockweiler Drive Extension Project 4.5 Geology/Soils SCH No. 2013082016 Page 4.5-16 City of Santa Clarita August 2017 Landslides No landslides have been mapped on the subject Project Site. Stability of cut slopes that are constructed at gradients of 2:1 or shallower are anticipated to expose favorable bedding conditions and be grossly stable. However, cut slopes will require subsurface investigation to determine the specific geologic conditions for evaluation by the Geotechnical Engineer. Remedial measures will be required where ascending or descending cut slopes are not stable as determined by geologic or geotechnical stability analyses. A study should be conducted at the design stage to confirm the geologic conditions of natural slopes. This study should include subsurface investigation to determine the specific geologic conditions for evaluation by the Geotechnical Engineer. Remedial measures will be required where ascending or descending slopes are not stable as determined by geologic or geotechnical stability analyses. A study should be conducted at the design stage to evaluate potential debris flow hazards on steep natural slopes ascending from the proposed road alignments. Avoidance of the hazard by selective structural locations, construction of impact or debris walls and/or debris basins, control of run-off or removal of loose surficial materials can be used to mitigate debris flow hazards. Therefore, with implementation of Mitigation Measure 4.5-1, impacts with respect to landslides would be less that significant. Soil Stability Rapidly buried silty sediments such as thick colluvium and alluvium may be subject to hydro - compression. A study should be conducted to evaluate the hydro -compression potential of colluvial deposits and portions of the alluvium. Materials characterized as susceptible to hydro -compression tests in the laboratory can be mitigated by removal prior to the placement of fill. Specific recommendations should be provided at the design stage. The bedrock is moderately consolidated, which indicates that grading operations can be performed with conventional equipment. Cobbles and small boulders are likely present within the alluvium and bedrock. This oversize material may present difficulties during cutting operations with some types of equipment. In addition, oversize material will require special handling during fill construction. A study should be conducted to evaluate the expansive potential of fine-grained soils during the design stage. If potentially expansive units are encountered in the street grades during construction, they should be evaluated by Expansion Index (EI) tests by the Project Geotechnical Engineer relative to mitigations. The expansive material can be removed to a specified depth determined by the Project Geotechnical Engineer and replaced with soil with very low to non -expansive characteristics. Alternatively, the expansive soil may be treated with additives to lower the expansion potential. Soils on the Project Site may be corrosive to concrete and ferrous metals. Soil moisture, chemistry, and other physical characteristics all have important effects on corrosivity. Testing during development will indicate what special measures, such as cement type in concrete and corrosion protection for metallic pipes, may be required for construction. Planting and irrigation of cut slopes and fill slopes should be included in future design phases in order to improve surficial stability of slopes and to mitigate potential Lyons Avenue/Dockweiler Drive Extension Project 4.5 Geology/Soils SCH No. 2013082016 Page 4.5-17 City of Santa Clarita August 2017 for erosion. Therefore, with implementation of Mitigation Measure 4.5-1, impacts with respect to soil stability would be less that significant. Construction Considerations Rippability The Project Site is underlain by Saugus Formation, Pacoima Formation, Quaternary alluvium and artificial fill. These materials can be ripped with standard grading equipment. Oversized Material The alluvial and bedrock materials underlying the site may contain significant quantities of oversized material. Additionally, the dumped fill located along the southwest bank of Newhall Creek contains common blocks of asphalt and concrete as well as scattered boulders, car parts, and other oversized debris. Any oversized material that may be encountered during construction should not be incorporated into potential compacted fill during grading operations. Specifications and guidelines for handling and disposal should be addressed by the project geotechnical engineer at the design stage. Expansion Potential of Soils The site alluvial materials are generally granular and are not typically expansive in nature. However, fine-grained units of the Saugus Formation are known to have significant expansion potential when exposed to water. In addition, Pacoima formation bedrock, artificial fill, colluvium and alluvial deposits present at the site may contain material with significant expansion potential. Expansive materials at the site should be evaluated by the Project Geotechnical Engineer during the grading plan stage of development. Expansion potential of site soils can be mitigated by controlling the water content and density of fill soils, by specifying embedment and reinforcement of structures, and by removing the expansive materials and replacing them with compacted material with low expansion potential. Soil Corrosivity Past experience with similar soils on nearby sites suggests that the on -site soils likely have a low concentration of sulfate and chloride, and low acidity. This indicates a low potential for corrosion of concrete and, therefore, it is anticipated that Type I or II Portland cement will be satisfactory for use at the site. The resistivity of similar soils near the site tested by this firm indicates that they are typically moderately corrosive to ferrous metals. The corrosive characteristics of the site soils should be verified with laboratory testing at the design stage. If corrosive soils are encountered, options to mitigate potential corrosive soils include protective wraps and coatings for buried metal pipes and special types of cement that are resistant to corrosion. Shrinkage and Bulking of Materials Typically, soil, colluvium, uncompacted artificial fill, alluvial deposits, and terrace deposits (i.e. Pacoima formation bedrock) reduce in volume ("shrink") by up to about 10 percent when excavated and Lyons Avenue/Dockweiler Drive Extension Project 4.5 Geology/Soils SCH No. 2013082016 Page 4.5-18 City of Santa Clarita August 2017 subsequently recompacted. In contrast, Saugus Formation bedrock typically increases in volume ("bulk") by up to about 5 percent when excavated and recompacted. In order to evaluate the cut -fill balance of the proposed grading, shrinkage/bulking of on -site materials including landslide debris should be estimated at the design stage. Retaining Walls The grades at the northeast end of Lyons Avenue and adjacent portions of Railroad Avenue will need to be raised in order to tie into the existing grade at the railroad crossing. It is the geotechnical engineer's understanding that retaining walls may be used to accommodate the changes from the proposed grades to adjacent properties proposed to remain at existing grades. Geotechnical parameters for these walls and for design of the proposed box culvert and associated wing walls for the Newhall Creek crossing should be addressed at the design stage. Oil Wells and Water Wells Review of the Munger Map Book and California Division of Oil and Gas records indicates that no oil wells have been drilled on or immediately adjacent to the site. If any undocumented oil wells are encountered during future construction operations at the site, their location(s) should be surveyed and the current well conditions evaluated. Review of LACFCD records indicates that water wells have been drilled in the vicinity of the proposed road alignments. If one of these water well is within the proposed road alignment, or if a water well is encountered during future construction operations at the site, the location should be surveyed and the potential impacts to well conditions should be evaluated. Therefore, with implementation of Mitigation Measure 4.5-1, impacts relating to geology and soils would be less that significant. 4.5.4 CUMULATIVE IMPACTS Geotechnical impacts related to future development in the City of Santa Clarita would involve hazards related to site -specific soil conditions, erosion, and ground -shaking during earthquakes. Such conditions are site -specific and would not be common to (nor shared with, in an additive sense) the impacts on other sites that are not physically connected. Cumulative development in the area would increase the overall population for exposure to seismic hazards by increasing the number of people potentially exposed. However, with adherence to applicable State and Federal regulations, buildings codes and sound engineering practices, geologic hazards could be reduced to less -than -significant levels. Furthermore, development of each of the related projects and the Proposed Project would be subject to uniform site development and construction review standards that are designed to protect public safety. Therefore, cumulative geotechnical impacts would be less than significant. 4.5.5 MITIGATION MEASURES 4.5-1 The Proposed Project shall be designed and constructed in accordance with the City and State Building Codes and shall adhere to all modern earthquake standards, including the recommendations provided in the Project's Geotechnical Report, which shall be reviewed by the Lyons Avenue/Dockweiler Drive Extension Project 4.5 Geology/Soils SCH No. 2013082016 Page 4.5-19 City of Santa Clarita August 2017 City's Building and Safety Division. 4.5-2 Prior to the issuance of a grading permit, the Applicant shall provide grading plans to the City's Building and Safety Division for review and approval. Grading plans shall comply with the City's requirements for slope stability. Grading plans shall also comply with City requirements for stability under static and pseudo static loading conditions to mitigate risks associated with earthquake induced landslides. 4.5.6 LEVEL OF SIGNIFICANCE AFTER MITIGATION With the implementation of mitigation measure listed above, impacts related to geology and soils would be less than significant. Lyons Avenue/Dockweiler Drive Extension Project 4.5 Geology/Soils SCH No. 2013082016 Page 4.5-20 4. ENVIRONMENTAL IMPACT ANALYSIS 6. HYDROLOGY / WATER QUALITY 4.6.1 INTRODUCTION This section describes existing hydrology and water quality conditions in the project area and its immediate surroundings and addresses the federal state and local regulations and standards that govern impacts to hydrology, water quality and drainage as it pertains to the Project. Following a description of the regulations and existing conditions, potentially significant impacts associated with the Proposed Project are identified, along with mitigation measures to reduce potential project impacts. This section is heavily based on the findings and conclusions as presented in the following technical report: • Hydraulic and Scour Analysis Newhall Creek at Proposed Dockweiler Road Bridge, Newhall, California, prepared by Rivertech, Inc., dated February 2015 ("Hydraulic Report"), which is provided in Appendix G of this Draft EIR. 4.6.2 REGULATORY SETTING Federal Regulations National Flood Insurance Program The National Flood Insurance Act of 1968 and the Flood Disaster Protection Act of 1973 mandate the Federal Emergency Management Agency (FEMA) to evaluate flood hazards. FEMA provides flood insurance rate maps (FIRMS) for local and regional planners to promote sound land use and floodplain development, identifying potential flood areas based on the current conditions. To delineate a FIRM, FEMA conducts engineering studies referred to as flood insurance studies (FIS). Using information gathered in these studies, FEMA engineers and cartographers delineate special flood hazard areas (SFHA) on FIRMS. The Flood Disaster Protection Act requires owners of all structures in identified SFHAs to purchase and maintain flood insurance as a condition of receiving federal or federally -related financial assistance, such as mortgage loans from federally -insured lending institutions. Community members within designated areas are able to participate in the National Flood Insurance Program (NFIP) afforded by FEMA. The NFIP is required to offer federally -subsidized flood insurance to property owners in those communities that adopt and enforce floodplain management ordinances that meet minimum criteria established by FEMA. The National Flood Insurance Reform Act of 1994 further strengthened the NFIP by providing a grant program for state and community flood mitigation projects. The act also established the Community Rating System, a system for crediting communities that implement measures to protect the natural and beneficial functions of their floodplains, as well as manage erosion hazards. Lyons Avenue/Dockweiler Drive Extension Project 4. Hydrology / Water Quality SCH No. 2013080216 Page 4.6-1 City of Santa Clarita August 2017 Clean Water Act The United States Environmental Protection Agency (EPA) regulates water quality under the Clean Water Act (also known as the Federal Water Pollution Control Act). Enacted in 1972, and significantly amended in subsequent years, the Clean Water Act is designed to restore and maintain the chemical, physical, and biological integrity of waters in the United States. The Clean Water Act provides the legal framework for several water quality regulations, including National Pollutant Discharge Elimination System (NPDES) Permits, effluent limitations, water quality standards, pretreatment standards, anti - degradation policy, non -point source discharge regulation, and wetlands protection. The Clean Water Act requires NPDES permits for the discharge of pollutants to waters of the United States. The Clean Water Act requires that the EPA establish regulations for permitting of municipal and industrial storm water discharges under the NPDES permit program. The regulations require that municipal separate storm sewer system (MS4) discharges to surface waters be regulated by a NPDES permit. In implementing the Clean Water Act, the EPA has delegated the responsibility for administration of portions of the Clean Water Act to state and regional agencies. The Clean Water Act requires states to adopt water quality standards for receiving water bodies and to have those standards approved by the EPA. Water quality standards consist of designated beneficial uses for a particular receiving water body (e.g., wildlife habitat, agricultural supply, fishing, etc.), along with water quality criteria necessary to support those uses. Water quality criteria are prescribed concentrations or levels of constituents, such as lead, suspended sediment, and fecal coliform bacteria, or narrative statements that represent the quality of water that support a particular use. Federal Antidegradation Policy The Federal Antidegradation Policy (Title 40, CFR § 131.12) requires states to develop statewide anti - degradation policies and identify methods for implementing them. Pursuant to this policy, state anti - degradation policies and implementation methods shall, at a minimum, protect and maintain: (1) existing in -stream water uses; (2) existing water quality where the quality of the waters exceeds levels necessary to support existing beneficial uses, unless the state finds that allowing lower water quality is necessary to accommodate economic and social development in the area; and (3) water quality in waters considered an outstanding national resource. State permitting actions must be consistent with the Federal Antidegradation Policy. State And Local Regulations California Porter -Cologne Act The Porter -Cologne Water Quality Control Act (embodied in the California Water Code) established the principal California legal and regulatory framework for water quality control. The California Water Code authorizes the State Water Resources Control Board (SWRCB) to implement the provisions of the Federal Clean Water Act including the authority to regulate waste disposal sites and to require cleanup of discharges of hazardous materials and other pollutants. The California Water Code also establishes reporting requirements for unintended discharges of hazardous substance, sewage, or oil or petroleum Lyons Avenue/Dockweiler Drive Extension Project 4. Hydrology / Water Quality SCH No. 2013082016 Page 4.6-2 City of Santa Clarita August 2017 products. Under the California Water Code, the State of California is divided into nine regions governed by regional water quality control boards (RWQCB) that, under the guidance and review of the SWRCB, implement and enforce provisions of the California Water Code and the Clean Water Act. Each RWQCB must formulate and adopt a water quality control plan (Basin Plan) for its region. The Basin Plan must conform to the policies set forth in the California Water Code and established by the SWRCB in its state water policy. The California Water Code also provides RWQCBs the authority to include within its regional plan water discharge prohibitions applicable to particular conditions, areas, or types of waste. Los Angeles Regional Board Basin Plan The Los Angeles Regional Board's Basin Plan is designed to preserve and enhance water quality and protect the beneficial uses of all regional waters. Specifically, the Basin Plan: (i) designates beneficial uses for surface and ground waters; (ii) sets narrative and numerical objectives that must be attained or maintained to protect the designated beneficial uses and conform to the state's antidegradation policy; and (iii) describes implementation programs to protect all waters in the Region. In addition, the Basin Plan incorporates (by reference) all applicable State and Regional Board plans and policies and other pertinent water quality policies and regulations. Those of other agencies are referenced in appropriate sections throughout the Basin Plan. California Toxics Rule The EPA has established water quality criteria for certain toxic substances via the California Toxics Rule. The California Toxics Rule establishes acute (i.e., short-term) and chronic (i.e., long-term) standards for bodies of water such as inland surface waters and enclosed bays and estuaries that are designated by the Los Angeles Regional Water Quality Control Board (LARWQCB) as having beneficial uses protective of aquatic life or human health. Due to the intermittent nature of storm water runoff, especially in southern California, the acute criteria are considered to be more relevant to storm water than are the chronic criteria. California Toxics Rule criteria for certain metals are expressed as a function of hardness because hardness and/or water quality characteristics that are usually correlated with hardness can reduce or increase the toxicities of some metals. Hardness is used as a surrogate for a number of water quality characteristics that affect the toxicity of metals: increasing hardness has the effect of decreasing the toxicity of metals. At higher hardness values for the receiving water, copper, lead, and zinc are more likely to be bound with components in the water column; this in turn reduces the bioavailability and resulting potential toxicity of these metals. Therefore, the California Toxics Rule criteria increase with increasing levels of hardness. Lyons Avenue/Dockweiler Drive Extension Project 4. Hydrology / Water Quality SCH No. 2013082016 Page 4.6-3 City of Santa Clarita August 2017 Construction Permits Pursuant to the Clean Water Act Section 402(p), requiring regulations for permitting of certain storm water discharges, the SWRCB has issued a statewide General Permit for Stormwater Discharges Associated with Construction Activity and Land Disturbance Activities (Order No. 2010-0014-DWQ, adopted by the SWRCB on November 16, 2010 and effective February 14, 2011). Under this Construction General Permit, discharges of storm water from construction sites with a disturbed area of one or more acres are required to either obtain individual NPDES permits for storm water discharges or be covered by the Construction General Permit. Coverage under the Construction General Permit is accomplished by completing and filing permit registration documents, which include a Notice of Intent (NOI), Storm Water Pollution Prevention Plan (SWPPP), and other documents required by this General Permit, and mailing the appropriate permit fee to the State Water Board, prior to the commencement of construction activity. SWPPPs incorporate erosion control, sediment removal, and construction waste management control measures during construction, site stabilization measures in the short-term post -construction period, and may identify best management practices (BMPs) for post - construction land use. Dischargers must file a Notice of Termination with the Regional Water Board when construction is complete and final stabilization has been reached or ownership has been transferred. The discharger must certify that all State and local requirements have been met in accordance with this General Permit. In order for construction to be found complete, the discharger must install post -construction storm water management measures and establish a long-term maintenance plan. Los Angeles County MS4 Permit The State's Municipal Storm Water Permitting Program regulates storm water discharges from Municipal Separate Storm Sewer Systems (MS4s). Under Phase I of the Program, which started in 1990, the RWQCBs have adopted NPDES storm water permits for medium (serving between 100,000 and 250,000 people) and large (serving 250,000 people) municipalities. Most of these permits were issued to a group of co-permittees encompassing an entire metropolitan area. In 2001, the LARWQCB issued an NPDES Permit and Waste Discharge Requirements (Order No. 01- 182) under the Clean Water Act and the Porter -Cologne Act for discharges of urban runoff in public storm drains in Los Angeles County. The Permit was most recently amended on April 14, 2011, pursuant to the peremptory writ of mandate in L.A. Superior Court Case No. BS122724, which voided and set aside a 2006 amendment. The Permittees are the Los Angeles County incorporated cities (including the City but excluding the City of Long Beach) and the County (collectively "the Co-permittees"). An important element incorporated into the NPDES MS4 Permit is the requirements associated with development or redevelopment of a site. The NPDES MS4 Permit requires many development projects to incorporate permanent (post -construction) storm water mitigation measures. These measures are addressed by developers through the preparation of a Standard Urban Stormwater Mitigation Plan (SUSMP) or a Site -Specific Mitigation Plan. The primary purpose of these plans is to reduce the quantity Lyons Avenue/Dockweiler Drive Extension Project 4. Hydrology / Water Quality SCH No. 2013082016 Page 4.6-4 City of Santa Clarita August 2017 and improve the quality of storm water runoff that leaves a site. To implement the requirements of the NPDES permit, the Co-permittees have created development planning guidance and control measures that control and mitigate storm water quality and quantity impacts to receiving waters as a result of new development and redevelopment. The Co-permittees are also required to implement other municipal source detection and elimination programs, as well as maintenance measures. Floodplain Management Pursuant to City of Santa Clarita Municipal Code (Chapter 10.06) the City of Santa Clarita regulates development within flood -prone areas via a City Floodplain Management Ordinance. This ordinance states that within special flood hazard areas no structure or land shall be constructed, located, extended, converted, or altered without full compliance with the terms of the ordinance and without obtaining a floodplain area development permit before any construction or other development begins within any area of special flood hazard. The City has adopted its floodplain management ordinance to implement the NFIP and other federal requirements established by FEMA. The City has adopted Chapter 11.60 of the Los Angeles County Code by reference, which establishes floodway maps, governs land uses and construction of structures within floodways, and establishes water surface elevations. Floodplains are divided into two types of hazard areas: • The "floodway," which is the portion of the stream channel that carries deep, fast moving water (usually defined as the area needed to contain a 100-year storm flow); and • The "flood fringe" area, the remainder of the floodplain outside the floodway, which is subject to inundation from shallow, slow -moving water. The standards described below are required for all types of construction in all areas of special flood hazards. Drainage requirements set forth by the City are also addressed in other portions of the Uniform Development Code and in the Building Code, in order to ensure that stormwater flows are directed away from buildings into drainage devices to prevent flooding. Stormwater and Urban Runoff Pollution Control Stormwater and Urban Runoff Pollution Control Section 10.04.070 of the City's Municipal Code implements federal and state water runoff and discharges within the City of Santa Clarita. Each person applying to the City for a grading or building permit, for projects for which compliance with regulations governing State Construction Activity Stormwater Permits (SCASP) is required, must submit satisfactory proof to the City: • (i) NOI to comply with the SCASP has been filed; and • (ii) That a stormwater pollution prevention plan has been prepared before the City shall issue any grading or building permit on the construction project. A copy of the NOI and the SWPPP shall Lyons Avenue/Dockweiler Drive Extension Project 4. Hydrology / Water Quality SCH No. 2013082016 Page 4.6-5 City of Santa Clarita August 2017 be maintained on site during grading and construction and shall be made available for inspection, review and copying upon the request of any City inspector. It shall be a violation of this chapter for any person or entity required under federal or state law to comply with the requirements for SCASP for construction activity in the City to conduct, authorize or permit construction activities in the City at any facility which discharges to the City's MS4 without complying with all applicable requirements for a SCASP. Each person applying for a grading or building permit for any project for which compliance with regulations governing SCASP is not required shall submit to the City for information, and shall implement a grading and construction activity runoff control program adequate to accomplish all of the following: 1. Retain on site the sediments generated on or brought to the project site, using treatment control or structural BMPs; 2. Retain construction -related materials and wastes, spills and residues at the project site and prevent discharges to streets, drainage facilities, the MS4, receiving waters or adjacent properties; 3. Contain non-stormwater runoff from equipment and vehicle washing at the project site; and 4. Control erosion from slopes and channels through use of effective BMPs, such as limitation of grading during the wet season, inspection of graded areas during rain events; planting and maintenance of vegetation on slopes, if any, and covering any slopes susceptible to erosion. Additionally, Section 10.04.070 requires that: • No person generating or producing pavement sawcutting wastes in any street, curb or sidewalk in the City shall fail to recover and properly dispose of such sawcutting wastes, and in no case shall such wastes be permitted or suffered to enter any part of the MS4, including, but not limited to, any storm drain; • No person performing street and road maintenance in any street in the City shall fail to manage street and road maintenance materials in a manner which prevents such materials from being discharged to the MS4; and • No person shall wash any concrete truck or any part of any concrete truck, including, but not limited to, any chute, pump or tools, in any place in the City except an area designated for that purpose by the City, if the City has designated such a place. No person shall permit or suffer any concrete rinseate or washwater from any truck, pump, tool, or equipment to enter any drain, open ditch, street or road or any catch basin or any other part of the MS4. Existing Conditions Local Hydrology The existing Project Site is generally pervious. The site consists of improved segments of Railroad Avenue and Lyons Avenue roadways and undeveloped land to the east extending towards The Master's University and Arch Street. The west end of the Project Site encompasses portions of Newhall Creek and Lyons Avenue/Dockweiler Drive Extension Project 4. Hydrology / Water Quality SCH No. 2013082016 Page 4.6-6 City of Santa. Clarita August 2017 traverses a storage yard utilized by Los Angeles County Department of Public Works. The portion of the Project Site that includes the intersection of Railroad Avenue and 13'b Street is developed with existing road surface and an at grade crossing. The Newhall Creek study reach boundaries, as described in the Hydraulic Report, are Placerita Creek and the survey limits, approximately 3,000 feet downstream of the SR14 crossing, at the downstream and upstream limits, respectively. Based on the available topographic survey, the average channel slope of 0.4% was applied to determine the downstream normal depth, which is added to the channel invert to arrive at the starting water -surface elevation. Figure 4.6-1 depicts the topography and river stationing. The proposed bridge, an extension of Dockweiler Road and Lyons Avenue over Newhall Creek Channel crossing, was modeled using the culvert hydraulics computer program HY-8. One of the sources of hydrologic data utilized for the Hydraulic Report is the Los Angeles County Flood Control District (LACFCD) Design Division, who provided hydrologic data for Newhall Creek Channel, which was part of 2001 to 2005 LACFCD comprehensive study for the South Fork of the Santa Clara River watershed. Peak flows for Newhall Creek sub -areas are provided for 50-year clear -flow, 50-year burned -flow and 50-year bturnedlbulked (Capital Flood). The second source of hydrologic data is the Federal Emergency Management Agency, as part of the Flood Insurance Study, which provides 100-year peak flows. Table 4.6-1 below, summarizes the flood flows.

Based on the LACFCD Sedimentation Manual recommendation for the Santa Clara River watershed, it is prescribed that the Newhall Creek be improved as a soft bottom channel with protected levees. To convey the Capital Flood, a discharge of 9,200 cubic feet per second (ffs), the proposed channel section will require a trapezoidal section with an 80-foot wide base and 2.1 lined side slopes. This section is similar to the existing upstream improvements at Del Oro Street crossing with Newhall Creek. HEC-RAS model input and output data, including cross sections and detailed tables are provided in the Appendix of the Hydraulic Report. The proposed four 24-feet wide and 8-feet deep opening reinforced concrete bridge will accommodate the Capital Flood. Lyons AvenuelDockA-eiler Drive Extension Project 4.

The locations of nearby water wells are shown in Figure 4.5-3, Water Well Location Map in Section 4.5. The historic ground water levels for each well obtained from LACFCD records are provided in Table 4.5-1, Summary of LAFCD Water Well Data, in Section 4.5. In addition, ground water was not encountered in subsurface explorations to a depth of 50 feet in the alluvium for the adjacent Old Town Newhall Library. However, temporary perched ground water conditions may exist below Newhall Creek following periods of significant rainfall and runoff. A low potential exists for temporary, perched ground water conditions to develop within the bedrock of the Pacoima formation. Perched ground water can contribute to slope instability in natural slopes and cut slopes. To prevent build-up of water, subdrains are typically recommended in canyon areas in which fill will be placed and back drains for slopes that are to be constructed as Stability Fills or Buttress Fills. Due to the historic high ground water elevations and the elevated nature of portions of the road alignment, ground water is not expected to significantly affect the project, provided the proposed grading is evaluated from a geotechnical standpoint during the design stage and the geotechnical recommendations are implemented during construction. 1 Inundation and Flooding No dams currently exist in the Newhall Creek Drainage and the Project Site is not in a dam inundation area per the Flood and Inundation Hazard Map of the Los Angeles County Safety Element of the General Plan. The potential for dam inundation is therefore considered nonexistent. a The western portion of the roadway extension that crosses Newhall Creek, is located in a "Zone A", as indicated in the National Flood Insurance Rate Map for Los Angeles County, which indicates a special flood hazard area that is subject to inundation by the 1% annual chance flood (100-year flood) .3 The floodplain map for Capital peak flow is provided in the Appendix of the Hydraulic Report. The cut sections using the Watershed Modeling System (WMS) river tools were imported into HECRAS as georeferenced geometry. This geometric data was then modified and amended to accurately reflect the hydraulic characteristics, e.g., bridges, channel banks, roughness, etc. The model includes the Railroad Avenue and Southern Pacific Railway bridges. Boundary conditions (i.e., flows and starting water -surface elevations) were added to complete the model. Figure 4.6-2 and Figure 4.6-3 depict the hydraulic sections and existing conditions of the water profile, respectively.

The existing Newhall Creek Channel does not have the capacity to convey the FIS 100-year and the Capital Flood flow rates. As a result, the 100-year model results show that a significant percentage of the flow spill out the main channel and flood the railroad, entering the Railroad Avenue. 4.6.3 ENVIRONMENTAL IMPACTS Thresholds of Significance In accordance with Appendix G to the CEQA Guidelines, a project could result in a significant impact if the project would result in one or more of the following: (a) Violate any water quality standards or waste discharge requirements; Substantially deplete groundwater supplies or interfere substantially with groundwater recharge such that there would be a net deficit in aquifer volume or a lowering of the local groundwater table level (e.g., the production rate of pre-existing nearby wells would drop to a level which would not support existing land uses or planned uses for which permits have been granted); (b) Substantially alter the existing drainage pattern of the site or area, including through the alteration of the course of a stream or river, in a manner, which would result in substantial erosion or siltation on- or off -site; (c) Substantially alter the existing drainage pattern of the site or area, including through the alteration of the course of a stream or river, or substantially increase the rate or amount of surface runoff in a manner which would result in flooding on- or off -site; (d) Create or contribute runoff water which would exceed the capacity of existing or planned stormwater drainage systems or provide substantial additional sources of polluted runoff, (e) Otherwise substantially degrade water quality; (f) Place housing within a 100-year flood hazard area as mapped on a federal Flood Hazard Boundary or Flood Insurance Rate Map or other flood hazard delineation map; (g) Place within a 100-year flood hazard area structures which would impede or redirect flood flows; (h) Expose people or structures to a significant risk of loss, injury or death involving flooding, including flooding as a result of the failure of a levee or dam; or (i) Expose people or structures to a significant risk of loss, injury or death involving inundation by seiche, tsunami, or mudflow. Lyons Avenue/Dockweiler Drive Extension Project 4. Hydrology / Water Quality SCH No. 2013082016 Page 4.6-12 City of Santa Clarita August 2017 Project Impacts Water Quality Construction During construction, sediment is typically the constituent of greatest potential concern. The greatest risk of soil erosion during the construction phase occurs when site disturbance peaks due to grading activity and removal and re -compaction or replacement of fill areas. Sediment is not typically a constituent of concern during the long-term operation of developments similar to the Project because sites are usually paved or landscaped, and proper drainage infrastructure is installed. Other pollutants that could affect surface -water quality during the Project construction phase include petroleum products (gasoline, diesel, kerosene, oil, and grease), hydrocarbons from asphalt paving, construction equipment leaks, paints and solvents, detergents, fertilizers, and pesticides (including insecticides, fungicides, herbicides, and rodenticides). Development projects within the City of Santa Clarita are required to prepare and implement a SWPPP, in accordance with the NPDES General Permit for Discharges of Storm Water Associated with Construction Activity and Land Disturbance Activities. The site -specific SWPPP would be prepared prior to earthwork activities and would be implemented and monitored for compliance during project construction activities. The SWPPP would include BMPs and erosion control measures to prevent pollution in storm water discharge. Typical BMPs that could be used during construction include good -housekeeping practices (e.g., street sweeping, proper waste disposal, vehicle and equipment maintenance, concrete washout area, materials storage, minimization of hazardous materials, proper handling and storage of hazardous materials, etc.) and erosion/sediment control measures (e.g., silt fences, fiber rolls, gravel bags, storm water inlet protection, and soil stabilization measures, etc.). The SWPPP would be subject to review and approval by the City for compliance with the City's Stormwater and Urban Runoff Pollution Control, Section 10.04.070 of the City's Municipal Code. Additionally, all Project construction activities would comply with the City's grading permit regulations, which require the implementation of grading and dust control measures, including a wet weather erosion control plan if construction occurs during rainy season, as well as inspections to ensure that sedimentation and erosion is minimized. The site specific BMPs that are required to be incorporated into the Project's SWPPP are identified below in Section (3), Regulatory Compliance. Therefore, through compliance with NPDES requirements and City grading regulations, the Project's construction impacts related to water quality would not violate any water quality standards or waste discharge requirements or otherwise substantially degrade water quality. Construction -related impacts to hydrology and water quality would therefore be less than significant. Operation Once the Proposed Project has been constructed, urban runoff could include the above -mentioned contaminants. Trace metals from road surface runoff and landscape maintenance debris may be mobilized in storm runoff and in dry -season in "nuisance flows" from landscape irrigation. Liquid product spills occurring at the Project Site could also enter the storm drain. Dry product spills could enter Lyons Avenue/Dockweiler Drive Extension Project 4. Hydrology / Water Quality SCH No. 2013082016 Page 4.6-13 City of Santa Clarita August 2017 the storm drain via runoff in wet weather conditions or dry -season "nuisance flows." The existing Project Site is generally pervious. In accordance with NPDES requirements, the Project Applicant would be required to have a Project -specific SUSMP in place during the operational life of the Project to address the management of runoff from the proposed roadway extension. The SUSMP would include site design, source control, low -impact development, and treatment control BMPs and would address site design BMPs (such as minimizing impervious areas, maximizing permeability, minimizing directly connected impervious areas, and creating reduced or "zero discharge" areas); incorporate applicable source control BMPs; incorporate treatment control BMPs as described in the Los Angeles County SUSMP; describe long-term operation and maintenance requirements for the treatment control BMPs; and describe the mechanism for funding the long-term operation and maintenance of the treatment control BMPs. The final selection of BMPs would be completed through coordination with the City. Also, per the NPDES, the storm water quality plan would be subject to review and approval by the City for compliance with the City's Development Best Management Practices Handbook, Low Impact Development Manual, Part B Planning Activities. Therefore, implementation of the storm water quality plan as discussed above water quality impacts during operation would be less than significant. Inundation and Flooding The implementation of the proposed bridge and channel widening are two significant components of the post -project hydraulic model. The bridge has four 25-foot wide and 8-foot deep openings. The approach to the bridge is an improved channel that is trapezoidal in shape with an 80-foot bottom width and 2:1 aide slopes. The hydraulic sections and input from the existing condition model was the basis for the post project with the implementation of the proposed bridge and channel widening. The results of the HEC- RAS hydraulic model output indicate that the proposed bridge and channel improvement will accommodate the Capital Flood, i.e., no overtopping of the road, and will not create any flood hazard for the adjacent railroad and proposed street improvements. The bridge conveys both the 50-year bum/bulk and FIS 100-year flood flows with more than 2 feet of freeboard. Figure 4.6-4 illustrates the resulting water -surface profiles for the post -project scenario. The detailed input and output of the post -project scenario hydraulic model is exhibited in the Appendix of the Hydraulic Report. The results of this study provide the calculated shear stress on the streambank. In order to protect the streambank from erosion, a lining with a permissible shear stress, rp, greater than r, must be installed. Riprap and vegetation linings are recommended for the high and moderate shear zones, respectively. Regulatory Compliance The Proposed Project will span the Newhall Creek. Roadway construction will include a new bridge across Newhall Creek and provide embankment protection to the roadway and creek. The Newhall Creek improvements will be designed in accordance with current regulatory and State permitting agencies, which include: Lyons Avenue/Dockweiler Drive Extension Project 4.

As such, future development would likely result in a net beneficial impact by reducing surface water runoff flows during storm events and improving the overall quality of water draining from the area. Additionally, similar to the Proposed Project, each of the applicants of proposed development projects would be required to prepare and implement a SWPPP (construction) and SUSMP (operation) and would be subject to preliminary Site Plan review by the City to determine what drainage improvements and BMPs would be required to ensure no significant water quality issues. As discussed above, the Proposed Project would not result in any significant hydrology and water quality impacts and together with future development, would not create an impact that is cumulatively considerable, as each development project would have to comply with site specific development standards and state water quality regulations. Compliance with these standards would ensure that the related projects would further the objectives of applicable regional water quality plans. Therefore, cumulative impacts to hydrology and water quality would not be cumulatively considerable. 4.6.5 MITIGATION MEASURES No project specific mitigation measures are required. 4.6.6 LEVEL OF SIGNIFICANCE AFTER MITIGATION With implementation of the regulatory compliance measures identified above, construction and operational hydrology and water quality impacts would be less than significant prior to mitigation. Therefore no mitigation measures are required. Lyons Avenue/Dockweiler Drive Extension Project 4. Hydrology / Water Quality SCH No. 2013082016 Page 4.6-17 4. ENVIRONMENTAL IMPACT ANALYSIS 7. LAND USE AND PLANNING 4.7.1 INTRODUCTION The following analysis discusses the consistency of the Proposed Project with the corresponding land use and zoning designations and guidelines within the City of Santa Clarita. The following land use analysis is presented as an informational document to disclose the project's consistency or inconsistency with the existing adopted regional land use plans and local land use and zoning regulations. 4.7.2 ENVIRONMENTAL SETTING Existing and Adjacent Land Uses The existing Project Site consists of improved segments of Railroad Avenue and Lyons Avenue roadways and undeveloped land to the east extending towards Dockweiler Drive. The west end of the Project Site encompasses portions of Newhall Creek and traverses a storage yard utilized by Los Angeles County Department of Public Works. The portion of the Project Site that includes the intersection of Railroad Avenue and 13th Street is developed with existing road surface and an at -grade crossing. The UP/Metrolink Railroad line crosses the Project Site east of the intersection of Railroad Avenue and Lyons Avenue Railroad and at the intersection of Railroad Avenue and 13t'' Street. The portion of the Project Site to the east of the intersection of Railroad Avenue and Lyons Avenue is bounded by commercial and industrial uses to the north a landscape nursery to the south east, the Jan Heidt Newhall Metro Link Station and open space to the south, and the Old Town Newhall Library and commercial uses to the west across Railroad Avenue. The portion of the Project Site to the east of the intersection of Railroad Avenue and 13t'' Street is bounded by undeveloped land to the north, commercial and industrial uses to the east, Newhall Creek to the south, and one-story commercial buildings to the west, across Railroad Avenue. Relevant Land Use Policies The Project Site is subject to the designations and regulations of several local and regional land use and zoning plans. At the regional level, the Project Site is located within the planning area of the Southern California Association of Governments (SLAG), the region's federally -designated metropolitan planning organization, and therefore is subject to SCAG's Regional Comprehensive Plan and Guide (RCPG) and the 2016 Regional Transportation Plan/Sustainable Communities Strategy (RTP/SCS). The Project is also located within the South Coast Air Basin (SCAB) and therefore is within the jurisdiction of the South Coast Air Quality Management District (SCAQMD) and is subject to SCAQMD's Air Quality Management Plan (AQMP). The Project Site is located within the Los Angeles Watershed Basin and is subject to the regulatory oversight of the Los Angeles Regional Water Quality Control Board (LARWQCB). In addition, the Project Site is subject to the Congestion Management Plan (CMP) for Los Angeles County. Lyons Avenue/Dockweiler Drive Extension Project 4.7. Land Use and Planning SCH No. 2013082016 Page 4.7-1 of Santa Clarita August 2017 At the local level, development of the Project Site is guided by the General Plan of the City of Santa Clarita (General Plan). The General Plan provides general guidance on land use issues and planning policy for the entire City. The Circulation Element of the General Plan is applicable to the Proposed Project, as it promotes a variety of techniques for improving mobility within the City of Santa Clarita. The City of Santa Clarita Municipal Code (SCMC) guides zoning, land use decisions and development patterns for individual properties. Within the City of Santa Clarita, the Project Site is located in the Placerita Canyon Special Standards District (PCSSD) and is part of the North Newhall Area (NNA), which includes a Mixed -Use Overlay Zone. In addition, the Project Site is located in the City's Compass Blueprint Concept Plan (Concept Plan) area, and is adjacent to the Old Town Newhall Specific Plan (Specific Plan) area. Southern California Association of Governments SCAG is a federally designated Metropolitan Planning Organization (MPO) representing six counties (Ventura, Orange, San Bernardino, Riverside, Imperial, and Los Angeles). SCAG is mandated by federal and State law to research and draw up plans for transportation, growth management, hazardous waste management, and a regional growth forecast that is the foundation for these plans and regional air quality plans developed by the South Coast Air Quality Management District (SCAQMD). SCAG divides its planning area into 15 subregions. The Project Site is located within the North Los Angeles County subregion. As part of its regional planning efforts, SCAG prepared and has adopted the 2012 Regional Transportation Plan/Sustainable Communities Strategy (RTP/SCS) to address regional growth and measure progress toward achieving regional planning goals and objectives. Regional Transportation Plan/ Sustainable Communities Strategy (RTP/SCS) On April 2016, SCAG's Regional Council adopted the 2016-2040 Regional Transportation Plan/Sustainable Communities Strategy (RTP/SCS): A Plan for Mobility, Accessibility, Sustainability, and a High Quality of Life. The RTP/SCS is the culmination of a multi -year effort involving stakeholders from across the SCAG Region. The 2016-2040 RTP/SCS balances the Southern California region's future mobility and housing needs with economic, environmental, and public health goals. Based on the regional growth projections in the 2016-2040 RTP/SCS, the City of Los Angeles had an estimated permanent population of approximately 3,845,500 persons, approximately 1,325,500 residences, and 1,696,400 jobs.' By the year 2040, SCAG forecasts the City of Los Angeles will increase to 4,609,400 persons (or a 20 percent increase from the year 2012) with approximately 1,690,300 residences (or an 28 percent increase from the year 2012) and approximately 2,169,100 jobs (or an 1 Southern California Association of Government, 2016-2040 Regional Transportation Plan / Sustainable Communities Strategy, Demographics and Growth Forecast Appendix, adopted April 2016. Lyons Avenue/Dockweiler Drive Extension Project 4.7. Land Use and Planning SCH No. 2013082016 Page 4.7-2 of Santa Clarita 2017 approximate 28 percent increase from year 2012)2 . The RTP/SCS incorporates SCAG's Compass Growth Vision, adopted in 2004, which encourages better relationships between housing, transportation, and employment. The Growth Vision is driven by four key principles: (1) Mobility — Getting where we want to go, (2) Livability — Creating positive communities, (3) Prosperity — Long-term health for the region, and (4) Sustainability — Preserving natural surroundings. Additionally, the Compass Growth Vision incorporates a 2% Growth Strategy that will increase the region's mobility by putting new employment centers and new neighborhoods near major transit systems. Compass Blueprint Concept Plan As part of SCAG's Sustainability Program, the Compass Blueprint program partners SCAG with local governments to develop demonstration projects that promote land use and transportation planning and implement regional visions at the local level. Compass Blueprint is guided by four core principles, which include, mobility, livability, prosperity and sustainability. The City of Santa Clarita's Compass Blueprint Concept Plan is a conceptual land use and circulation plan that guides development in the Newhall community north of Old Town Newhall and east of Railroad Avenue. The Concept Plan consists of a mix of commercial, office and residential uses that serve to strengthen the Old Town Newhall area, encourage the use of public transit, and be compatible with the rural and equestrian character of Placerita Canyon. South Coast Air Quality Management District The Project Site is located within the South Coast Air Basin (SCAB) and is therefore within the jurisdiction of the South Coast Air Quality Management District (SCAQMD). In conjunction with SLAG, the SCAQMD is responsible for formulating and implementing air pollution control strategies. The Air Quality Management Plan (AQMP) is intended to establish a comprehensive regional air pollution control program leading to the attainment of state and federal air quality standards in the SCAB area. Air quality impacts of the Proposed Project and consistency of the Project impacts with the AQMP is analyzed in greater detail in Section 4.2, Air Quality of this Draft EIR. Congestion Management Program The Congestion Management Program (CMP) is a state -mandated program that was enacted by the State Legislature with the passage of Proposition I I I in 1990. The program is intended to address the impact of local growth on the regional transportation system. As required by the 2010 Congestion Management Program for Los Angeles County, a Traffic Impact Assessment (TIA) has been prepared to determine the potential impacts on designated monitoring locations on the CMP highway system. The analysis has been prepared in accordance with procedures outlined in the 2010 Congestion Management Program for Los Angeles County, County of Los Angeles 2 Ibid. Lyons Avenue/Dockweiler Drive Extension Project 4.7. Land Use and Planning SCH No. 2013082016 Page 4.7-3 of Santa Clarita August 2017 Metropolitan Transportation Authority. Refer to Section 4.9, Transportation and Traffic, for a complete discussion and project impact analysis related to the CMP. The City of Santa Clarita General Plan Land use decisions are guided by the City of Santa Clarita's General Plan, which establishes goals and policies related to land use, transportation, population growth and distribution, development, open space, resource preservation and utilization, air and water quality, noise impacts, public safety, infrastructure, and other related physical, social, and economic factors. As stated in the General Plan, in addition to serving as a basis for local decision making, the General Plan establishes a clear set of development guidelines for citizens, developers, neighboring jurisdictions and agencies, and provides the community with an opportunity to participate in the planning process. The purpose of this General Plan is to comply with state requirements and to provide the City with a comprehensive, long-range policy guideline for future development. Pursuant to the City of Santa Clarita's General Plan the portion of the Project Site located at 13th Street and Railroad Avenue and Lyons Avenue and Railroad Avenue has a General Plan land use designation of Mixed Use Neighborhood (MXN). The General Plan states that areas with a MXN designation should be developed to create neighborhoods that combine residential uses with complementary commercial services, including retail and office uses. MXN zoned areas should be located in close proximity to public transit and provide roadway and trail linkages to adjacent development. Circulation Element The Circulation Element of the General Plan aims to guide the development of efficient, cost-effective and comprehensive transportation systems that are consistent with regional plans and local needs of the City of Santa Clarita. Planning for the location and capacity of circulation improvements serves to enhance economic strength and quality of life in Santa Clarita. The Santa Clarita Valley's circulation system provides vital connections linking neighborhoods, services, and employment centers throughout the community and the region. A comprehensive transportation network of roadways, multi -use trails and bike paths, bus transit, and commuter rail provides mobility options to Santa Clarita residents and businesses. The Circulation Element identifies and promotes a variety of techniques for improving mobility, which includes: development of alternative travel modes and support facilities; increased efficiency and capacity of existing systems through management strategies; and coordination of land use planning with transportation planning by promoting concentrated, mixed -use development near transit facilities. The extension of Dockweiler Drive is identified in the Circulation Element as a major new roadway. The proposed roadway from the Arch Street/12th Street/ Placerita Canyon/Dockweiler Drive intersection to the future intersection of Lyons Avenue and Dockweiler Drive will be a two-lane facility with a 13- foot landscaped parkway/sidewalk on each side. The proposed roadway from the Lyons Avenue and Dockweiler Drive intersection to the Master's University property line will be a 2-lane facility with a 12- Lyons Avenue/Dockweiler Drive Extension Project 4.7. Land Use and Planning SCH No. 2013082016 Page 4.7-4 of Santa Clarita August 2017 foot raised landscaped median, and 13-foot parkway/sidewalk on each side. The median lanes will be 12 feet wide and the parking lanes 9 feet wide with a 6-foot bike lane. The parking lanes will be capable of being converted into a travel lane to create an ultimate 4-lane facility in compliance with the City's General Plan. The typical right-of-way (R/W) width will be 92 feet. Santa Clarita Municipal Code All development activity on the Project Site is subject to the Santa Clarita Municipal Code (SCMC), particularly Chapter I7, Zoning. The Planning and Zoning Code establishes requirements for the Project Site, with respect to permitted uses, building height, density, yard setbacks, and parking. The portion of the Project Site located at 13a' Street and Railroad Avenue and Lyons Avenue and Railroad Avenue is currently zoned for MXN (Mixed -Use Neighborhood). Pursuant to SCMC Chapter 17.35, Section 020, the residential density range in mixed -use neighborhoods designates a minimum of 6 to a maximum of 18 dwelling units per acre, and maximum floor area ratio (FAR) for the nonresidential portion of the development is 0.5. The maximum building height of a project is 50 feet. The portion of the Project Site that crosses the UP/Metrolink Railroad line is zoned for PI (Public Institutional). The PI zoning designation identifies lands that are used for various types of public or/and community serving facilities owned and operated by public agencies, special districts, nonprofit organizations and other entities. Allowable uses include civic and governmental offices, public works yards, public or private schools, libraries, day care centers, airports, hospitals and supporting medical facilities, museums, fire stations, police stations, landfills, and prisons. Oak Trees Native oak trees are protected under City of Santa Clarita Oak Tree Ordinance (Ordinance No. 89-10, passed by the City Council on April 25, 1989) and the City's Oak Tree Preservation and Protection Guidelines (adopted September 11, 1990). The City of Santa Clarita's Oak Tree Preservation ordinance (Unified Development Code §17.51.040) requires the preservation of all healthy oak trees and that removal, cutting, pruning, relocation, damage, or encroachment into the protected zone of any oak trees measuring 6 inches or larger in circumference (DBH, diameter at breast height) on public or private property can only be done in accordance with a valid oak tree permit issued by the City. Placerita Canyon Special Standards District Chapter 17.39, Section 020, of the SCMC establishes the PCSSD design standards in order to protect, preserve and enhance the secluded, rural and equestrian character of the Placerita Canyon community. The PCSSD ensures that development is compatible with the characteristics of surrounding single-family residential neighborhoods and that development does not negatively impact light, air, and privacy of the existing single-family residences. The PCSSD serves to help mitigate the cumulative impacts of development and ensure reasonable access to public riding and hiking trails. Lyons Avenue/Dockweiler Drive Extension Project 4.7. Land Use and Planning SCH No. 2013082016 Page 4.7-5 of Santa Clarita 2017 North Newhall Area The North Newhall Area (NNA) was established to stimulate development and redevelopment activities in the area north of Old Town Newhall. Most of the NNA is located within the PCSSD. The northern portion of the NNA is undeveloped with a hillside to the north, oak trees and Placerita Creek. The commercial corridor along the west side of Railroad Avenue consists of mixed retail and commercial uses. The SCMC establishes guidelines for the NNA to ensure that it provides buffering, transitional densities and protection for the existing developed areas and not intrude in or change the character of Placerita Canyon located east of the NNA. Additionally, a Mixed Use Overlay Zone was adopted to encourage a mix of residential, commercial, employment, and institutional uses along the Newhall Avenue and Lyons Avenue corridors. The Mixed Use Overlay Zone serves to revitalize older commercial corridors, increase opportunities for infill housing, and encourage development that creates pedestrian - oriented neighborhoods. Old Town Newhall Specific Plan As shown in Figure 2-6, of the Project Description, portions of the Project Site are located in the Old Town Newhall Specific Plan area. The Specific Plan encourages mixed -use and transit -oriented development in the historic community of Newhall, in order to promote new investment, spur economic development, and create new residential opportunities in this area. The Specific Plan transformed San Fernando Road into a pedestrian -oriented 'Main Street' with public buildings, parking garages, an open-air market and mixed commercial and residential development. 4.7.3 ENVIRONMENTAL IMPACTS Thresholds of Significance In accordance with Appendix G of the State CEQA Guidelines, a project may have a significant environmental impact if it were to: (a) Physically divide an established community; (b) Conflict with any applicable land use plan, policy, or regulation of an agency with jurisdiction over the project (including, but not limited to the general plan, specific plan, coastal program, or zoning ordinance) adopted for the purpose of avoiding or mitigating an environmental effect; or (c) Conflict with any applicable habitat conservation plan or natural community conservation plan. Project Impacts The Proposed Project would not physically divide an established community. Rather, the extension of Dockweiler Drive is proposed by the Circulation Element to be one of the primary east -west arterials through the City of Santa Clarita that would provide a through connection from Sierra Highway to Lyons Avenue/Dockweiler Drive Extension Project 4.7. Land Use and Planning SCH No. 2013082016 Page 4.7-6 City of Santa Clarita August 2017 Railroad Avenue. The Project includes the extension of a segment of Lyons Avenue from Railroad Avenue to the future connection with Dockweiler Drive at The Master's University site and northwest towards the intersection of Arch Street and 12a` Street, The Proposed Project will include re -profiling the intersection of Lyons Avenue and Railroad Avenue to allow the construction of a new SCRRA/UP railroad at -grade crossing east of Railroad Avenue. The Proposed Project's anticipated closure of the at - grade crossing at the intersection of Railroad Avenue and 13d' Street would not divide an established community as the re-routing of traffic from the 13ffi Street at -grade crossing to the proposed alignment extending from Lyons Avenue to the northern proposed five -leg intersection at Arch Street/lfl Street/Placerita Canyon would provide an alternative route into the Placenta Canyon neighborhood. The proposed intersection alignment of Lyons Avenue and Dockweiler Drive would include monument signage to properly identify the entrance to the Placenta Canyon community as a residential community with no through access. Traffic signage and a dedicated right -turn alignment will appropriately direct through -traffic to the southern alignment of the roadway towards Dockweiler Drive to prevent passing motorists from inadvertently making a left turn into the Placerta Canyon neighborhood. The Proposed roadway alignment will span the Newhall Creek which will also serve to increase pedestrian and vehicular access in the area. Accordingly, implementation of the Proposed Project would not disrupt or divide the physical arrangement of the established community, and no impact would occur. Land Use Compatibility The Proposed Project would not conflict with any applicable land use plans, policies, or regulations. Provided below is a plan consistency analysis with the applicable governing plans that guide land use development in the project area. Regional Transportation Plan/ Sustainable Communities Strategy As discussed in the consistency analysis in Table 4.7-1 below, the Proposed Project would substantially comply with the goals identified in the 2016-2040 RTP/SCS.

City of Santa Clarita Municipal Code Pursuant to the Santa Clarita Municipal Code (SCMC), a portion of the Project Site at 13ffi Street and Railroad Avenue acid Lyons Avenue is currently zoned for MXN (Mixed -Use Neighborhood) and a portion of the Project Site that crosses the UP/Metrolink Railroad line is zoned for PI (Public Institutional). The Proposed Project does not include the development of residential, commercial or industrial buildings and therefore no impact would occur with respect to zoning. As discussed above and in Sections 2.0, Project Description, and 4.3, Biological Resources, native oak trees are protected under City of Santa Clarity Oak Tree Ordinance (Ordinance No. 89-10, passed by the City Council on April 25, 1989). The City of Santa Clarita requires that all potential impacts to oak trees be preceded by an application to the City that includes a detailed oak tree report and that loss of or damage to protected oaks be mitigated at a minimum 2:1 ratio. Based upon the development and grading footprint of the Proposed Project, constriction of the proposed roadway would require the removal of two oak trees. As such, the Proposed Project would require the approval of an Oak Tree Permit and Hillside Review Permit at such time as development occurs or when funding of roadway construction becomes available. These entitlements will be obtained at such time as the proposed alignment is approved and roadway funding is available to implement the Project. With procurement of the required Oak Tree Permit and Hillside Review Permits, land use impacts would be less than significant. Cite of Santa Clarita General Plan Pursuant to the City of Santa Clarita's General Plan the portion of the Project Site located at 13* Street and Railroad Avenue and Lyons Avenue and Railroad Avenue has a General Plan land use designation of Mixed Use Neighborhood (MW. The portion of the Project Site that crosses the UP/Metrolink Railroad line is zoned for PI (Public Institutional). The Proposed Project does not include the development of any residential, commercial or industrial buildings and as such, no impact would occur with respect to the land use designation of the Project Site. Circulation Element The extension of Dockweiler Drive is identified in the Circulation Element as a major new roadway. The extension, as proposed in the Circulation Element, would complete the approved roadway connection from Railroad Avenue to Sierra Highway. Construction of the extension would include a new four -lane secondary highway, connecting Dockweiler Drive from Railroad Avenue to Leonard Tree Lane. The Lyons Avenue/Dockweiler Drive Extension Project 4.7. Land Use and Planning SCH No. 2013082016 Page 4.7-9 City of Santa Clarita August 2017 Proposed Project includes the extension of Lyons Avenue from Railroad Avenue to the approved alignment of Dockweiler Drive at The Master's University site. As shown in Table 4.7-2 below, the Proposed Project would be in substantial compliance with the goals, objectives and polices of the Circulation Element. Table 4.7-2 City- of Santa Clarita Circulation Element Consistency Anahvsis City- of Santa Clarita Circulation Element I Project Consistency Analysis Street and Hiuhwav System Goals. Uhiectives and Policies Goal C 2: A unified and well -maintained network of streets and highways which provides safe and efficient movement of people and goods between neighborhoods, districts, and regional centers_ while maintaining community character. Objective C 2.1: Implement the Circulation Plan (as shown on Exhibit C-2) for streets and highways to meet existing and future travel demands for mobility. access, connectivity, and capacity. Policy C 2.1.1: Protect mobility on arterial highways by limiting excessive cross traffic. access points, and turning movements; traffic signals on arterial highways should be spaced at least 1/2-mile apart, and the minimum allowable separation should be at least 1/i- niile. Consistent: The Proposed Project would expand ail existing roadway system by linking Lyons Avenue, from Railroad Avenue, to the future connection of Dockweiler Drive at The Master's University site. The roadway expansion includes connection points to the 12'h Street/Arch Street/Placerita Canyon intersection_ which will link Old Town Newhall with the Placenta Canyon neighborhood. and The Master's University. The design of Dockweiler Drive will include Class H pedestrian sidewalks and bike lanes on each side. Bike Lane connectors are proposed from Dockweiler Drive to connect to the Proposed Class I Bike Path along Railroad Avenue and the existing Class III Bike Path along Railroad Avenue. As such the Proposed Project is consistent with this goal. Consistent: The expansion of Lyons Avenue from Railroad Avenue. to the future connection of Dockweiler Drive at The Master's University site is consistent with the proposed roadway as indicated on Exhibit C-2 of the Circulation Plan. The extension of the proposed roadway (Lyons Avenue) was designated as a Secondary Highway. Thus. the Project is consistent with the Circulation Plan acid the approved Master's University Master Plan, in which Dockweiler Drive was designated as a 4-lane Secondary Highway. The proposed roadway will be a 2-lane facility with a 12- foot raised landscaped median, and 13-foot parkway/sidewalk on each side. The parking lanes will be capable of being converted into a travel lane to create an ultimate 4-lane facility in compliance with the City's General Plan connecting Dockweiler Drive from Railroad Avenue to Leonard Tree Lane. The proposed roadway expansion will meet existing and future travel demands for mobility, access, connectivity. and capacity and is therefore consistent with this objective. Partially Consistent: The Proposed Project will include re -profiling the intersection of Lyons Avenue and Railroad Avenue to allow the construction of a new SCRRA/UP railroad at -grade crossing east of Railroad Avenue. Consistent with the CPUC policy for limiting new at -grade crossings. the Project proposes the closure of an at -grade crossing east of the intersection of Railroad Avenue and 13`h Street. However, the Proposed Lyons Avenue/Dockweiler Drive Extension Project 4.7. Land Use and Planning SCH No. 2013082016 Page 4.7-10 City of Santa Clarity August 2017 C my of Santa Claritar Circulation Element Project Consistency Analysis Project would result in a signalized T-intersection at the proposed intersection of Lyons Avenue and Dockweiler Road, which is less than 0.10 mile east of the existing signalized intersection of Lyons Avenue and Railroad Avenue. Thus, the Project would be partially consistent with this policy. Policy C 2.1.2: Enhance connectivity of the roadway Consistent: The Proposed Project will span Newhall network to the extent feasible given the constraints of Creek to the east of the intersection of Railroad Avenue topography, existing development patterns. and and Lyons Avenue.

The roadway construction will construct a new bridge across Newhall Creek and provide embankment protection to the roadway and creek. The Newhall Creek improvements will be designed in accordance with current regulatory and State permitting agencies. As such, the Proposed Project would be consistent with this standard. Consistent: As discussed in Section 4.6. Hydrology/ Water Quality, the hydrology and scour analysis concluded that the Proposed bridge sparuiing the banks of Newhall Creek would accommodate the Capital Flood, i.e.. no overtopping of the road. and will not create any flood hazard for the adjacent railroad and proposed street improvements. The bridge conveys both the 50-year biuu %ulk and F IS 100-year flood flows with more than 2 feet of freeboard. Therefore, the construction of the bridge would not be detrimental to adiacent unstrearn or downstream nromerties. Consistent: A Notice of Preparation for the Draft EIR for the Proposed Project was filed on August 5, 2013 and was available for public review and continent until September 3. 2013. A public scoping meeting for the Draft EIR was held on August 21. 2013 at City Hall in Santa Clarita. Through these outreach efforts the City received continent letters from various community members including the Placenta Canyon Property Owners' Association. Public comments were considered in the preparation of this Draft EIR. As such, the Proposed Project is consistent with this standard.

The Proposed also includes the closure of an at -grade crossing east of the intersection of Railroad Avenue and 13" Street to minimize the number of at -grade crossings in the Newhall area and improve public safety. While the Project will increase traffic flows through the planned roadway extension, the design of Dockweiler Drive will include sidewalks for pedestrian use and Class II bike lanes on each side. Class H bike routes will provide a striped lane for one-way bike travel andwill be marked with signs and pavement striping. Therefore the Proposed Project would be consistent with this standard. Consistent: The Proposed Project has been planned with special consideration to avoid misdirecting through traffic into the Placerta Canyon neighborhood which does not provide through traffic to Sierra Highway for non-residents. The planned T intersection at Lyons Avenue and Dockwieler Drive will include a dual right turn lane souhbound and a single left turn lane northbound for eastbound traffic. For northbound traffic, the alignment would include a dual left turn lane and a single through lane. Appropriate signage would also be placed to warn drivers that Placerta Canyon does not provide through access to non-residents. Thus, the Project would be consistent with this Policy. Furthermore, the gate located at the western entrance to Placenta Canyon Road would remain. The gate provides restrictive access to residents of the Placenta Canyon neighborhood. As such, the Proposed Project would be consistent with this standard. Consistent: While the proposed monument signage has not yet been designed, as a city sponsored capital improvement project it is anticipated that the Proposed Project would be consistent with this policy in ensuring appropriate signage is provided informing motorists that the Placenta Canyon neighborhood does not provide through access to Siena Highway. Consistent: the Proposed Project's impact on transportation and traffic is based on the Traffic Study titled.

Consistent: Dockweiler Drive will include sidewalks for pedestrian use. Class 11 bike lanes on each side, and a multi -purpose trail on the east side. Class H bike routes will provide a striped lane for one-way bike travel and will be marked with signs and pavement striping. Multi -purpose trails are to be unpaved and will be available for equestrian, hiking. and mountain bike use. Potential Bike Lane connectors are proposed from Dockweiler Drive to connect to the Proposed Class I Bike Path along Railroad Avenue and the existing Class H Bike Path along Railroad Avenue. As such the Proposed Project is consistent with this standard. Not Applicable. This policy is not applicable to the Proposed Project as the Project is not located within or adjacent to the M-%VD right -or -way. Consistent. As discussed in Section 4.6. Hydrology/Water Quality, the LACFCD Sedimentation Manual recommendation for the Santa Clara River watershed prescribes that the Newhall Creek be improved as a soft bottom channel with protected levees. To convey the Capital Flood, a discharge of 9.200 cubic feet per second WAX the proposed channel section will require a trapezoidal section with an 80-foot wide base and 2:1 lined side slopes. This section is similar to the existing upstream improvements at Del Oro Street crossing with Newhall Creek. HEC-RAS model input and output data, including cross sections and detailed tables are provided in the Appendix of the Hydraulic Report. The proposed four 24-feet wide and 8-feet deep opening reinforced concrete bridge will accommodate the Capital Flood. Consistent: The proposed channel section will require a trapezoidal section with an 80-foot wide base and 2:1 lined side slopes.

Odd Town Newhall Specific Plan The Proposed Project would create a new segment of roadway that would connect Lyons Avenue to the existing roadways east of Railroad Avenue. The Proposed Project would improve local and regional circulation by connecting the Old Town Newhall community west of the Project Site to the Placerita Canyon community and The Master's University east of the Project Site and is therefore consistent with the Specific Plan. Compass Blueprint Concept Plan As described in the Concept Plan, the extension of Dockweiler Drive will be designed as a two-lane artery, which will become the primary route through the Concept Plan area east of Railroad Avenue. The proposed roadway from the Arch Street/12'h Street/ Placerita Canyon/Dockweiler Drive intersection to the future intersection of Lyons Avenue and Dockweiler Drive will be a two-lane facility with a 13-foot landscaped parkway/sidewalk on each side. The proposed roadway from the Lyons Avenue and Dockweiler Drive intersection to the Master's University property line will be a 2-lane facility with a 12- foot raised landscaped median, and 13-foot parkway/sidewalk on each side. The median lanes will be 12 feet wide and the parking lanes 9 feet wide with a 6-foot bike lane. The parking lanes will be capable of being converted into a travel lane to create an ultimate 4-lane facility in compliance with the City's General Plan. The typical right-of-way (RAW) width will be 92 feet. The Concept Plan proposes that Dockweiler Drive be a divided roadway with a wide center median to facilitate the efficient movement of traffic. Therefore the Proposed Project would be consistent with the Concept Plan. Conservation Plans The Project Site is not located in a habitat conservation plan or natural community conservation plan. The Project Site is largely surrounded by development and road networks and is not zoned for conservation. However, as discussed in Section 4.3 Biological Resources, two California Department of Fish and Wildlife (CDFW) jurisdictional features occur within the Project Site, the Newhall Creek and a small ephemeral drainage that is a tributary to Newhall Creek. The Project would result in both temporary and permanent impacts to the areas of the Newhall Creek and its associated tributary and are classified as "riverine and related permanent water, with continuous flow at least seasonally." With the implementation of MM 4.3-3. impacts to jurisdictional resources would be reduced to a less than significant level. Lyons Avenue/Dockweiler Drive Extension Project 4.7. Land Use and Planning SCH No. 2013082016 Page 4.7-22 of Santa Clarita August 2017 Additionally, Newhall Creek, which extends through the Project Site and provides passage through developed areas between the Santa Clarita River and the Angeles National Forest to the southeast and is considered a part of a wildlife movement or migration corridor. To limit impacts to wildlife movement, four 25-foot wide and 8-foot deep openings in a concrete box bridge with 80-foot wide soft base and 2:1 protected side slopes is proposed where the proposed roadway extension crosses Newhall Creek. As designed, this bridge would not result in any barrier to wildlife movement and would serve to protect Newhall Creek as a functioning wildlife movement corridor. The project as proposed would not result in significant impacts to wildlife movement. Therefore, with incorporation of Mitigation Measure 4.3-3 and the aforementioned project design features, impacts with respect to conservation plans would be less than significant. 4.7.4 CUMULATIVE IMPACTS Cumulative land use impacts could occur if other related projects in the vicinity of the proposed project site would result in land use incompatibility impacts in conjunction with the impacts of the proposed project. However, development of each related project would be subject to all adopted plans and regulations. Based upon the information available regarding the project growth as forecasted in the City's General Plan, it is reasonable to assume that the related projects under consideration in the surrounding community would implement and conform to local and regional planning goals and policies. Therefore, development of the Proposed Project would not result in a significant cumulative land use impact. 4.7.5 MITIGATION MEASURES No mitigation measures are required. 4.7.6 LEVEL OF SIGNIFICANCE AFTER MITIGATION The Proposed Project would result in less than significant impacts associated with land use and planning.

NOISE 4.8.1 INTRODUCTION This section evaluates the potential for noise and groundborne vibration impacts resulting from implementation of the Proposed Project, including impacts associated with a substantial temporary and/or permanent increase in ambient noise levels in the vicinity of the Project Site; exposure of people in the vicinity of the Project Site to excessive noise or groundborne vibration levels; and whether the anticipated exposure would exceed acceptable standards established in the local general plan or noise ordinance. Mitigation measures intended to reduce impacts to noise and vibration are proposed, where appropriate, to avoid or reduce significant impacts of the Proposed Project. Data used to prepare this analysis was obtained from the City of Santa Clarita General Plan Noise Element, the City of Santa Clarita Municipal Code (SCMC), the Federal Transit Administration Transit Noise and Vibration Impact Assessment (Harris Miller Miller & Hanson, 2006), and by measuring and modeling existing and future noise levels at the Project Site and surrounding areas. Noise prediction modeling conducted in this analysis is based on the Federal Highway Administration (FHWA) Highway Noise Prediction Model (FHWA-RD-77-108). The noise measurement data and modeling calculation worksheets are provided in Appendix H to this Draft EIR. Fundamentals of Sound And Environmental Noise Sound is technically described in terms of amplitude (i.e., loudness) and frequency (i.e., pitch). The standard unit of sound amplitude measurement is the decibel (dB). The dB scale is a logarithmic scale that describes the physical intensity of the pressure vibrations that make up any sound. The pitch of the sound is related to the frequency of the pressure vibration. Since the human ear is not equally sensitive to a given sound level at all frequencies, a special frequency -dependent rating scale has been devised to relate noise to human sensitivity. The A -weighted dB scale (dBA) provides this compensation by emphasizing frequencies in a manner approximating the sensitivity of the human ear. Noise, on the other hand, is typically defined as unwanted sound audible at such a level that the sound becomes an undesirable by-product of society's normal day-to-day activities. Sound becomes unwanted when it interferes with normal activities, causes actual physical harm, or results in adverse health effects. The definition of noise as unwanted sound implies that it has an adverse effect, or causes a substantial annoyance, to people and their environment. However, not every unwanted audible sound interferes with normal activities, causes harm, or has adverse health effects. For unwanted audible sound, i.e. noise, to be considered adverse it must occur with sufficient frequency and at such a level that these adverse impacts are reasonably likely to occur. Thresholds of significance, set forth below, are established to differentiate between benign, unwanted audible sound and potentially significant and adverse unwanted audible sound. Lyons Avenue/Dockweiler Drive Extension Project 4.8 Noise SCH No. 2013080216 Page 4.8-1 City of Santa. Clarita August 2017 A typical noise environment consists of a base of steady ambient noise that is the sum of many distant and indistinguishable noise sources. Superimposed on this background noise is the sound from individual local sources. These can vary from an occasional aircraft or train passing by to virtually continuous noise, such as traffic on a major highway. Table 4.8-1, Representative Environmental Noise Levels, illustrates representative noise levels in the environment.

Several rating scales have been developed to analyze the adverse effects of community noise on people. Since environmental noise fluctuates over time, these scales consider that the effects of noise on people is largely dependent upon the total acoustical energy content of the noise, as well as the time of day when the noise occurs. Those that are applicable to this analysis are as follows: • Lam,: An Lam,, or equivalent energy noise level, is the average acoustic energy content of noise for a stated period of time. Thus, the Let, of a time -varying noise and that of a steady noise are the same if they deliver the same acoustic energy to the ear during exposure. For evaluating community impacts, this rating scale does not vary, regardless of whether the noise occurs during the day or the night. • L.. The maximum instantaneous noise level experienced during a given period of time. Lyons Avenue/Dockweiler Drive Extension Project 4.8 Noise SCH No. 2013082016 Page 4.8-2 City of Santa Clarita August 2017 • Li,,: The minimum instantaneous noise level experienced during a given period of time. • CNEL: The Community Noise Equivalent Level (CNEL) is a 24-hour average Leq with a 5 dBA "weighting" during the hours of 7:00 P.M. to 10:00 P.M. and a 10 dBA "weighting" added to noise during the hours of 10:00 P.M. to 7:00 A.M. to account for noise sensitivity in the evening and nighttime, respectively. The logarithmic effect of these additions is that a constant 60 dBA 24 hour Leq would result in a CNEL of 66.7 dBA. Noise environments and consequences of human activities are usually well represented by median noise levels during the day, night, or over a 24-hour period. For residential uses, environmental noise levels are generally considered low when the CNEL is below 60 dBA, moderate in the 60-70 dBA range, and high above 70 dBA. Frequent exposure to noise levels greater than 85 dBA over time can cause temporary or permanent hearing loss. Examples of low daytime levels are isolated, natural settings with noise levels as low as 20 dBA and quiet suburban residential streets with noise levels around 40 dBA. Noise levels above 45 dBA at night can disrupt sleep. Examples of moderate level noise environments are urban residential or semi -commercial areas (typically 55-60 dBA) and commercial locations (typically 60 dBA). People may consider louder environments adverse, but most will accept the higher levels associated with more noisy urban residential or residential -commercial areas (60-75 dBA) or dense urban or industrial areas (65-80 dBA). It is widely accepted that in the community noise environment the average healthy ear can barely perceive CNEL noise level changes of 3 dBA. CNEL changes from 3 dBA to 5 dBA may be noticed by some individuals who are extremely sensitive to changes in noise. A 5 dBA CNEL increase is readily noticeable to most people, while a 10 dBA increase in sound pressure is perceived as a doubling of sound. However, there is no direct correlation between increasing or even doubling noise -generating uses and what is detectable by the human ear as an increase in noise level. The human ear perceives a 10 dB(A) increase in sound level to be a doubling of sound volume, but doubling the sound energy, i.e., the noise - generating activity, only results in a 3 dB(A) increase in sound. This means that a doubling of sound wave energy (e.g., doubling the volume of traffic on a roadway) would result in a barely perceptible change in sound level to the human ear. Thus, relatively sizeable increases in baseline noise generation are not necessarily perceived as significant noise increases by the human ear. Noise levels from a particular source generally decline as the distance to the receptor increases. Other factors, such as the weather and reflective barriers, also help intensify or reduce the noise level at any given location. A commonly used rule of thumb for roadway noise is that for every doubling of distance from the source (assume a starting point of 50 feet), the noise level is reduced by about 3 dBA at acoustically "hard" locations (i.e., the area between the noise source and the receptor is nearly complete asphalt, concrete, hard -packed soil, or other solid materials) and 4.5 dBA at acoustically "soft" locations (i.e., the area between the source and receptor is normal earth or has vegetation, including grass). Noise from stationary or point sources is reduced by about 6 to 7.5 dBA for every doubling of distance at acoustically hard and soft locations, respectively. Noise levels are also generally reduced by about 1 dBA for each 1,000 feet of distance due to air absorption. Noise levels may also be reduced by intervening structures — generally, a single row of buildings between the receptor and the noise source reduces the Lyons Avenue/Dockweiler Drive Extension Project 4.8 Noise SCH No. 2013082016 Page 4.8-3 City of Santa. Clarita August 2017 noise level by about 5 dBA, while a solid wall or berm can reduce noise levels by 5 to 10 dBA. The normal noise attenuation within residential structures with open windows is about 17 dBA, while the noise attenuation with closed windows is about 25 dBA.' Fundamentals Of Environmental Groundborne Vibration Vibration is sound radiated through the ground. Vibration can result from a source (e.g., train operations, motor vehicles, machinery equipment, etc.) causing the adjacent ground to move and creating vibration waves that propagate through the soil to the foundations of nearby buildings. This effect is referred to as groundborne vibration. The peak particle velocity (PPV) or the root mean square (RMS) velocity is usually used to describe vibration levels. PPV is defined as the maximum instantaneous peak of the vibration level and is typically used for evaluating potential building damage. RMS is defined as the square root of the average of the squared amplitude of the level. RMS velocity in decibels (VdB) is typically more suitable for evaluating human response. The background vibration velocity level in residential areas is usually around 50 VdB. The vibration velocity level threshold of perception for humans is approximately 65 VdB. A vibration velocity level of 75 VdB is the approximate dividing line between barely perceptible and distinctly perceptible levels for many people. Most perceptible indoor vibration is caused by sources within buildings, such as the operation of mechanical equipment, movement of people, or slamming of doors. Typical outdoor sources of perceptible groundborne vibration are construction equipment, steel -wheeled trains, and traffic on rough roads. If a roadway is smooth, the groundborne vibration from traffic is rarely perceptible. The range of interest is from approximately 50 VdB, which is the typical background vibration velocity level, to 100 VdB, which is the general threshold where minor damage can occur in fragile buildings, such as historic buildings. The general human response to different levels of groundborne vibration velocity levels is described in Table 4.8-2. Human Response to Different Levels of Groundborne Vibration.

Lyons Avenue/Dock-weiler Drive Extension Project 4.8 Noise SCH No. 2013082016 Page 4.8-4 City of Santa Clarita August 2017 4.8.2 REGULATORY SETTING City of Santa Clarita General Plan The California Government Code requires that a noise element be included in the general plan of each county and city in the state. Each local government's goals, objectives, and policies for noise control are established by the noise element of the general plan and the passage of specific noise ordinances. The Noise Element of the City of Santa Clarita General Plan, adopted in 2011, establishes policies for the compatibility of new land uses with various noise levels. These policies have been used to set and adopt exterior and interior noise compatibility criteria for various land uses within the City. The purpose of these criteria is to reduce the various potential effects of noise on people, including sleep disturbance, reduced physical and mental performance, annoyance, and interference with speech communication. The land use -noise compatibility guidelines for noise are identified in Figure 4.8-1, City of Santa Clarita Land Use Compatibility Guidelines for Noise. The Noise Element identifies 65 dBA and 55 dBA as the established exterior noise standards for residential uses during daytime and nighttime hours, respectively. When averaged over a 24-hour period, these noise levels average to approximately 65 dBA CNEL. The established exterior noise standard for schools, childcare centers, senior housing and other sensitive uses is also 65 dBA during the daytime hours when these uses would be occupied. The exterior noise standard for commercial and industrial uses is 80 dBA during the day and 70 dBA during nighttime hours. These levels average out to approximately 80 dBA CNEL over a 24-hour period. Part 2 of the Noise Element identifies the City's goals,' objectives,' and policies' that are associated with community noise impacts. Several of the goals, policies, and objectives listed in the Noise Element are oriented towards new residential, commercial or industrial development projects and are thus not applicable to the Proposed Project. As such, the goals,' objectives,' and policies' that are relevant to the Proposed Project are identified as follows: Noise Environment Goal N 1: A healthy and safe noise environment for Santa Clarita Valley residents, employees, and visitors. Objective N 1.1: Protect the health and safety of the residents of the Santa Clarita Valley by the elimination, mitigation, and prevention of significant existing and future noise levels. Policy N 1.1.1 Use the Noise and Land Use Compatibility Guidelines contained on Exhibit N-8 of the General Plan, which are consistent with State guidelines, as a policy basis for decisions on land use and development proposals related to noise. Policy N 1.1.2 Continue to implement the adopted Noise Ordinance and other applicable code provisions, consistent with state and federal standards, which establish Lyons Avenue/Dockweiler Drive Extension Project 4.8 Noise SCH No. 2013082016 Page 4.8-5 City of Santa Clarita August 2017 noise impact thresholds for noise abatement and attenuation, in order to reduce potential health hazards associated with high noise levels. Policy N 1.1.3 Include consideration of potential noise impacts in land use planning and development review decisions. Policy N 1.1.4 Control noise sources adjacent to residential, recreational, and community facilities, and those land uses classified as noise sensitive. Policy N 1.1.5 Monitor and update data and information regarding current and projected noise levels in the planning area. Policy N 1.1.6: Provide development review comments on projects proposed by other agencies and special districts that may generate noise impacts affecting land uses within the Santa Clarita Valley, including any freeway and high-speed rail projects. Reduction of Noise from Traffic Goal N 2: Protect residents and sensitive receptors from traffic -generated noise. Objective N 2.1: Prevent and mitigate adverse effects of noise generated from traffic on arterial streets and highways through implementing noise reduction standards and programs. Policy N 2.1.1: Encourage owners of existing noise -sensitive uses, and require owners of proposed noise sensitive land uses, to construct sound barriers to protect users from significant noise levels, where feasible and appropriate. Policy N 2.1.2: Encourage the use of noise absorbing barriers, where appropriate. Policy N 2.1.4: Reduce significant noise levels related to through -traffic in residential areas by promoting subdivision circulation designs to contain a hierarchy of streets, which efficiently direct traffic to highways. Policy N 2.1.6: Work with the City of Santa Clarita Transit to improve and expand current public transit services and routes to reduce vehicle trips and resulting noise levels. 2 Policies N 2.1.3, N 2.1.5 and N2.1.7 are not applicable to the Proposed Project. Lyons Avenue/Dockweiler Drive Extension Project 4.8 Noise SCH No. 2013082016 Page 4.8-6 City of Santa Clarita August 2017 Residential Neighborhoods Goal N 3: Protect residential neighborhoods from excessive noise. Objective N 3.1: Prevent and mitigate significant noise levels in residential neighborhoods. Policy N 3.1.3: Through enforcement of the applicable Noise Ordinance, protect residential neighborhoods from noise generated by machinery or activities that produce significant discernable noise exceeding recommended levels for residential uses. Policy N 3.1.4: Require that those responsible for construction activities develop techniques to mitigate or minimize the noise impacts on residences, and adopt standards that regulate noise from construction activities that occur in or near residential neighborhoods. City of Santa Clarita Municipal Code The City of Santa Clarita has also adopted a Noise Ordinance (Chapter 11.44 of the Santa Clarita Municipal Code), which identifies noise standards for various sources, specific noise restrictions, exemptions, and variances for sources of noise within the City. The Noise Ordinance applies to all noise sources with the exception of any vehicle that is operated upon any public highway, street or right-of- way, or to the operation of any off -highway vehicle, to the extent that it is regulated in the State Vehicle Code, and all other sources of noise that are specifically exempted. Noise Ordinance Section 11.44.040, Noise Limits, codifies the noise limits for various land uses that were established in the City of Santa Clarita General Plan. The City's noise limit standards for specified land uses are identified in Table 4.8-3, City Ordinance Noise Limits. Section 11.44.080 of the Noise Ordinance provides noise standards for construction and building activities. Pursuant to Section 11.44.080, no person shall engage in any construction work which requires a building permit from the City on sites within three hundred (300) feet of a residentially zoned property except between the hours of 7:00 A.M. to 7:00 P.M., Monday through Friday, and 8:00 A.M. to 6:00 P.M. on Saturday. Further, no work shall be performed on the following public holidays: New Year's Day, Independence Day, Thanksgiving, Christmas, Memorial Day and Labor Day. Emergency work as defined in Section 11.44.020(D) is permitted at all times. The Department of Community Development may issue a permit for work to be done "after hours"; provided, that containment of construction noises is provided.

SUITABLE INTERIOR ENVIRONMENTS One objective of locating residential units relative to a known noise source is to maintain a suitable interior noise environment at no greater than 45 d8 CNEL. This requirement, coupled with the measured or calculated noise reduction performance of the type of structure under consideration, should govern the minimum acceptable distance to a noise source. D. ACCEPTABLE OUTDOOR ENVIRONMENTS Another consideration. which in some communities is an overriding factor, is the desire for an acceptable outdoor noise environment. The acceptable outdoor noise level is 65 CNEL for rear yard areas, neighborhood parks, and pool rec+eation areas at fnulti-family developments C. PARKER Figure 4.8-1 ENVIRONMENTAL CONSULT:'.' a .

Existing Ambient Noise Levels Noise measurements were taken with a Larson Davis 831 sound level meter, which conforms to industry standards set forth in ANSI S1.4-1983 (R2001) - American National Standard Specification for Sound Level Meters. Consistent with protocol for community noise analysis, the sound level meter was programmed to record the "A" weighted average sound level (L q) over a continuous period of 15 minutes in duration. The average recorded sound event noise level (Leq), the minimum noise level (L„.) and the maximum noise level (L.,.) for each location is summarized below. The Southern Pacific Railroad rums parallel to Railroad Avenue in the vicinity of the Project Site and is a contributing factor affecting the ambient noise conditions. For this reason, noise measurements documented two conditions: ambient noise levels without train activity and ambient noise with train activity. Noise measurements documenting ambient noise levels took place at five locations discussed below. Noise Monitoring Locations are shown in Figure 4.8-2, below. A summary of noise observations at each of the measurement locations is provided below. Lyons AvenuelDock-weiler Drive Extension Project 4.8 Noise SCH No. 2013082016 Page 4.8-9 Solace.

Primary noise sources as this location included vehicle traffic, construction trucks, and delivery trucks. The ambient noise levels with and without a train passing by were identical (74.8 dBALeq) indicating there was no difference in the ambient noise levels when a train passed by as compared to when no trains were passing by. This observation is due to the relatively close distance between the primary noise source (traffic) and the monitoring location (adjacent sidewalk). During these measurement events, noise from a single vehicle passing by was noticeably louder than the noise attributable to the train passing by. • Location 2 is located on the north side of 13th Street approximately 250 feet east of the 13th Street and Railroad Avenue at -grade crossing. The primary source of noise at this location is vehicle and delivery truck traffic on 13th Street. The ambient noise levels without a train passing and with a train passing were 65.4 and 65.5 dBALeq, respectively, indicating there was no noticeable difference in the ambient noise levels when a train passed by as compared to when no trains were passing by. • Location 3 is located on the north side of Lyons Avenue at the intersection of Lyons Avenue and Main Street, directly in front of the Old Newhall Library. The primary sources of noise at this location are pedestrian activity and vehicle traffic. This site is within 350 feet of the railroad right-of-way. The ambient noise levels without a train passing and with a train passing were 66.3 and 65.7 dBALeq, respectively. Based on observations during both measurements, the predominant noise source was vehicular traffic on Lyons Avenue. The observed noise level was 0.6 dBA louder during the measurement event without the train passing. • Location 4 is located on the north side of Market Street at the Jan Heidt Metrolink Station approximately 250 feet east of the railroad right-of-way. The ambient noise at this location is influenced by vehicles on Market Street and Railroad Avenue and trains entering and leaving the Metrolink Station. The ambient noise levels without a train passing and with a train passing were 60.5 and 72.3 dBALeq, respectively, indicating an increase of approximately 11.8 dBA louder during the measurement event with the train stopping at the station. • Location 5 is located at the terminus of Aden Avenue, south of Placerita Canyon. This location is approximately 900 feet east of the railroad right -of way and the line -of -sight between the residences and the Old Town Newhall community to the west (including Railroad Avenue and the railroad right-of-way) is obscured by the intervening topography. Noise observations during this measurement reading were consistent with typical residential activities. During the measurement without a train event the following noise sources were noted: barking dogs, contractors dumping trash in bins, a lawn mower, a delivery truck, and a plane passing overhead. The ambient noise levels without a train passing and with a train passing were 41.9 and 47.0 dBALeq, respectively, indicating the ambient noise level increased by approximately 5.1 dBA when trains pass through the Metrolink Station.

Lyons Avenim/Dockweiler Drive Extension Project 4.8 Noise SCH No. 2013082016 Page 4.8-13 City of Santa Clarita August 2017 • A substantial temporary or periodic increase in ambient noise levels in the project vicinity above levels existing without the project. • For a project located within an airport land use plan or, where such a plan has not been adopted, within two miles of a public airport or public use airport, would the project expose people residing or working in the project area to excessive noise levels? • For a project within the vicinity of a private airstrip, would the project expose people residing or working in the project area to excessive noise levels? The following thresholds of significance are based on the City of Santa Clarita's City Land Use Compatibility Guidelines, as well as the noise standards outlined in the City's Noise Ordinance. Construction Noise Impacts Construction Noise A significant on -site noise impact would occur if off -site noise -sensitive land uses would be exposed to project -related construction noise levels originating on or off the project site that would be in violation of Sections 11.44.040, and Section 11.44.080 (as amended) of the City's Noise Ordinance. Construction and Operational Vibrations The City of Santa Clarita has not adopted any local threshold level for vibration impacts. In absence of local thresholds, the following analysis relies on the Federal Transit Administration Vibration Criteria for residential land uses .4 Per this guidance, a significant vibration annoyance impact would occur if the Proposed Project generated vibration levels in excess of 80 VdB at the receptor location. Operational Noise Mobile Source Noise Thresholds Evaluation of off -site mobile source noise impacts considers the City Land Use Compatibility Guidelines and community responses to changes in noise levels. Based on this information, a significant off -site project operational noise impacts would occur under the following criteria: • Criterion 1: An increase of 5.0 dB(A) or greater in noise level occurs from project -related activities if levels remain within the same land use compatibility classification (e.g., noise levels remain within the normally acceptable range); or • Criterion 2: An increase of 3.0 dB(A) or greater in noise level occurs from project -related activities which results in a change in land use compatibility classification (e.g., noise levels change from normally acceptable to conditionally acceptable); or 4 Caltrans, Transportation and Construction Vibration Guidance Manual (2013) at page 23. Lyons Avenue/Dockweiler Drive Extension Project 4.8 Noise SCH No. 2013082016 Page 4.8-14 City of Santa Clarita August 2017 • Criterion 3: Any increase in noise levels occurs where existing noise levels are already considered unacceptable under the City Land Use Compatibility Guidelines. The City's noise ordinance exempts emergency operations from noise regulation. Therefore, the assessment of roadway noise impacts does not account for roadway noise that may be generated by emergency vehicles. Interior Noise Thresholds A significant noise impact would occur if the Proposed Project causes or contributes to interior noise levels from exterior sources to exceed 45 dB(A) Ldt, or CNEL in any habitable room of a multi -residential use facility (e.g., hotels, motels, dormitories, long-term care facilities, and apartment houses and other dwellings, except detached single-family dwellings) with doors and windows closed. Project Impacts Construction -Related Noise Impacts Construction of the Proposed Project would require the use of heavy equipment for ground clearing, site grading, and roadway construction. Development activities would also involve the use of smaller power tools, generators, and other sources of noise. During each stage of development, there would be a different mix of equipment operating and noise levels would vary based on the amount of equipment in operation and the location of the activity. The U.S. Environmental Protection Agency (EPA) has compiled data regarding the noise generating characteristics of specific types of construction phases and specific construction equipment. These data are presented in Table 4.8-7 and Table 4.8-8 for a reference distance of 50 feet from the source. These noise levels can be expected to occur on a temporary and intermittent basis throughout the construction period. As discussed previously, Section 11.44.080 of the Santa Clarita Municipal Code prohibits construction work requiring a building permit on sites within 300 feet of a residentially zoned property from operating except between the hours of 7:00 A.M. and 7:00 P.M. Monday through Friday, and between 8:00 A.M. and 6:00 P.M. on Saturday. As such, construction activities would not measurably affect the L& noise levels or CNEL since no construction activities would occur after 7:00 P.M. The representative construction phasing and equipment noise levels identified in Tables 4.8-7 and 4.8-8 would, however, increase daytime ambient noise levels in excess of the noise limits set forth in Municipal Code Section 14.44.040, Noise Limits (See Table 4.8-3, above).

Using the reference noise level data presented in Table 4.8-8, it is estimated that several pieces of construction equipment operating simultaneously would generate a noise level of approximately 94.6 dBA. As shown in Figure 4.8-2 the sensitive receptors within 500 feet of the Project Site are the residential communities bound by Market Street to the north, the single-family homes to the north at the terminus of Aden Avenue, the residences west of railroad Avenue and north of Lyons Avenue. the Master's University Campus, and the Old Town Newhall Library.

Clarita August 2017 impacting each receptor are identified in Table 4.8-9, below. As shown in Table 4.8-9. when factoring in attenuation rates for distance over a soft (i.e., vegetated) ground surface, the anticipated construction noise levels are expected to exceed the City's daytime noise standards for residential uses (see Table 4.8- 3); although_, temporary and episodic construction noise levels would be similar to the existing noise levels of passing trains (see Table 4.8-5). As such, construction noise would produce noise levels that are similar to existing temporary and episodic noise levels. Nevertheless, construction noise would exceed the threshold levels, and the construction noise levels would therefore constitute a significant impact.

Construction -Related Groundborne Vibration Construction activities that would occur at the Project Site would involve the use of heavy earthmoving equipment and vibratory rollers, which have the potential to generate low levels of groundbome vibration. Table 4.8-10, below, identifies various vibration velocity levels at specific distances for the types of construction equipment that would operate at the Project Site during construction. Site clearing and grading activities would not occur within 100 feet of any occupied residential structure within the Project area. Based on the information in Table 4.8-10, the nearest homes to the north on Aden Avenue would be exposed to vibration levels in the range of 69 VdB, which is below the dividing line between barely perceptible and distinctly perceptible levels for many people. Also, as discussed previously, constriction activities that would occur within 300 feet of a residential zone would be limited Lyons Avenue/Dockweiler Drive Extension Project 4.8 Noise SCH No. 2013082016 Page 4.8-17 City of Santa. Clarita August 2017 to the hours of 7:00 A.M. through 7:00 P.M. Monday through Friday and 8:00 A.M. through 6:00 P.M. on Saturday. Therefore, vibration impacts would not occur during recognized sleep hours for residences. The Proposed Project would not generate vibration levels in excess of the 80 VdB threshold at any residences and/or buildings where people normally sleep. Thus, the Proposed Project's potential impact upon exposing persons to excessive groundborne vibration or groundborne noise levels would be less than significant.

Operational Noise Levels--Off-Site Roadway Noise Impacts The Proposed Project is anticipated to alter roadway traffic volumes, as the Proposed Project would create a new roadway segments and crossings, including removing the crossing at Railroad Avenue and 13`h Street and connecting Lyons Avenue to Dockweiler Drive, which would also include extending Dockweiler Drive to connect with Arch Street. Locations in the vicinity of the Lyons Avenue/Dockweiler Drive Extension and the crossing closure at 13th Street portions of the Proposed Project could experience slight changes in noise levels as a result of the change in traffic patterns. The proposed roadway crossing would be located at the intersection of Railroad Avenue and Lyons Avenue, where Location IT was monitored. The noise measurements recorded at Locations 2T and 4T are representative of what noise levels would be at the proposed railroad crossing at Lyons Avenue and Railroad Avenue, as these locations were proximate to the existing at grade crossings along Railroad Avenue at I P Street and Market Streets. The highest 15-minute average Leq noise level experienced during a train event at either location was 72.3 dB at Location 4T, which is approximately 2.5 dB lower than the 15-minute Leq noise level at Location IT (74.8 dB). A 2.5 dB change in the ambient noise level (either higher or lower) would be inaudible/imperceptible to the nearest sensitive receptors, which are the old Town Newhall Library (located 290 feet west) and the residences west of Railroad Avenue and north of Lyons Avenue (located 490 feet northwest). Furthermore, it is also important to note that the highest noise level (L.,) at Location IA (ambient noise level without a train crossing) was 92.0 dB which was attributable to heavy vehicle traffic such as transit buses, delivery trucks, and motorcycles. Therefore, heavy vehicle traffic is observed to contribute to higher noise levels than a passing train. The new noise sources from the proposed railroad crossing at Lyons Avenue and Railroad Avenue would have a less than significant impact on sensitive receptors. Lyons Avenue/Dockweiler Drive Extension Project 4.8 Noise SCH No. 2013082016 Page 4.8-18 City of Santa. Clarita August 2017 The changes in future noise levels along the study -area roadway segments in the Project Site vicinity are identified in Table 4.8-11, below. As shown, the Proposed Project's near term (Year 2019) impacts would increase local noise levels by a maximum of 2.7 dBA CNEL (at the location of Dockweiler Drive (between Sierra Highway and Valle del Oro), which is inaudible/imperceptible to most people and would not exceed the identified thresholds of significance. At all other roadway segments, the resulting noise levels are anticipated to decrease. As such the Proposed Project's potential to generate a substantial permanent increase in ambient noise levels in the project vicinity above levels existing without the project would be less than significant.

Operational Noise Lei-els - On -Site Roadway Noise Impacts The Proposed Project improvements which includes the 13d' Street crossing closure does not include modifications to roadway circulation and are not expected to affect on -site operational noise levels. This portion of the Proposed Project would result in a less than significant impact to on -site roadway operational noise. The Lyons Avenue/Dockweiler Drive Extension portion of the Proposed Project would result in a future roadway segment over an existing creek bed and over an area that is largely vacant and undeveloped. The proposed roadway segment would connect Arch Street to the future planned extension of Dockweiler Drive and would provide a link from Lyons Avenue crossing the Newhall Creek to the proposed extension of Dockweiler Drive. As shown in Figure 4.8-2, the proposed alignment would construct a Secondary Highway roadway segment within 130 feet of existing residential homes on Aden Avenue, within 245 feet of the residential uses on Market and Race Streets, and within 490 feet of The Master's University. Based on the noise prediction modeling using the FHWA's Highway Noise Prediction Model Lyons Avenue/Dockweiler Drive Extension Project 4.8 Noise SCH No. 2013082016 Page 4.8-19 City of Santa. Clarita August 2017 (FI WA-RD-77-108), the Future (2019) With Project noise levels on the new roadway segment from Lyons Avenue to Valle del Oro are expected to be 63.3 dBA (CNEL) within 50 feet of the centerline of the roadway. The resulting noise levels at the sensitive receptors identified in Table 4.8-12, below, would be below 52.9 dBA. It should be noted that the line of sight between the proposed roadway segment and Aden Avenue is blocked at its closest point by a ridgel me that extends approximately 20 feet higher thane the roadway surface elevation. The residences are also located at a lower surface elevation than the roadway. Thus, the topography in this area will provide additional attenuation of approximately 5 dBA Lm. In any case, the anticipated with Project noise levels at all off -site receptor locations would be within the "normally acceptable" range of noise for residential areas. Therefore, the Proposed Project's noise impacts would be less than significant.

Operational Noise Levels -- Railroad Crossing Bells The Proposed Project would result in the closure of the 13"' Street railroad right-of-way crossing and the improvement of a new at -grade railroad crossing at Lyons Avenue and Railroad Avenue. The closure of the existing at grade railroad crossing at 13'b Street would reduce the railroad warning signal bell levels in the vicinity of 13" Street and Railroad Avenue as the railroad crossing warning signal devices would be removed at this location and installed at a new at -grade crossing at Lyons Avenue and Railroad Avenue. As previously discussed and shown in Table 4.8-4 and 4.8-5 (ambient Noise Levels Without and With Train Events) and Figure 4.8-2, Noise Monitoring Location Map, the ambient noise levels with and without the railroad crossing signals activated produced a wide range of noise levels showing little to no effect at locations 1 through 3 (where local vehicle traffic noise was the dominant noise source) to an increase of up to 5.1 to 11.8 dBA Lq at locations 5 and 4 respectively. The relocation of the existing Lyons AvenuelDock-weiler Drive Extension Project 4.8 Noise SCH No. 2013082016 Page 4.8-20 City of Santa Clarita August 2017 railroad crossing signal at 13a' Street and Railroad Avenue approximately 1,150 feet south to the Lyons Avenue and Railroad Avenue crossing would not result in a noticeable change to the ambient noise levels during train events. Noise impacts from at -grade warning signals would be less than significant. 4.8.4 CUMULATIVE IMPACTS Cumulative impacts refer to two or more individual effects which, when considered together, are considerable or which compound or increase other environmental impacts. Cumulative impacts may be analyzed by considering a list of past, present, and probable future projects producing related or cumulative impacts. For purposes of assessing the Project's cumulative roadway noise levels, the Future Year 2035 Traffic Analysis was applied to the Federal Highway Administration (FHWA) Highway Noise Prediction Model (FHWA-RD-77-108). The Future Year 2035 traffic volumes were provided by the City of Santa Clarita using the Santa Clarita Valley Consolidated Traffic Model (SCVCTM) for the Buildout Year. Other Area Projects anticipated to be constructed by Year 2035 have been incorporated into the SCVCTM, and account for expected growth. The buildout includes construction of future roadways Golden Valley Road between Newhall Ranch Road to Valley Center Drive, Magic Mountain Parkway from Railroad Avenue to Via Princessa, and Via Princessa between Claibourne Lane and Sheldon Avenue. The future buildout SCVTM model also includes the proposed conceptual development of the North Newhall Specific Plan area an 809 dwelling unit plus an approximate 11-acre commercial land use. Based on this data, cumulative traffic -generated noise impacts were quantified based on the change in noise levels from the Future (2035) Without Project scenario and the Future (2035) With Project scenario, as shown in Table 4.8-13, below. As shown in Table 4.8-13, cumulative development with the Proposed Project would result in increased local noise levels by a maximum of 2.9 dBA CNEL at Lyons Avenue (between Main Street and Railroad Avenue), 2.3 dBA CNEL at Lyons Avenue (between Newhall Avenue and Main Street), and 2.4 dBA CNEL at Dockweiler Rd. (between Sierra Highway and Valle del Oro). At all other roadway segments, the noise levels are expected to remain unchanged or slightly decrease. This impact is largely due to the reduction in "cross valley" trip lengths and travel times and the diffusion of traffic volumes over the existing roadway segments. Because the resulting noise levels would be under 3 dBA, the resulting roadway noise level increase would not be considered substantial and, therefore, would not constitute a significant cumulative impact.

The following measures are recommended to reduce the potential noise levels associated with construction activities to the maximum extent feasible. 4.8-1. Pursuant to Section 11.44.080 of the City's Noise ordinance, no construction work shall occur within 300 feet of occupied residences except between the hours of 7:00 AM and 7:00 PM Monday through Friday, and between 8:00 AM and 6:00 PM on Saturday. No construction work shall occur on Sunday, New Year's Day, Independence Day, Thanksgiving Day, Christmas Day, Memorial Day, and Labor Day. 4.8-2. The construction schedule (including the various types of activities that would be occurring throughout the duration of construction phases, anticipated truck routes, and the potential for noise impacts along local roadways from construction -related vehicles) shall be prominently posted on -site during construction stages. When construction activities are anticipated to occur within 200 feet of residences, notice of the construction schedule shall be mailed to such residences two weeks prior to commencement of activity. 4.8-3. The phone number of the job superintendent shall be clearly posted at all construction entrances to allow for surrounding owners and residents to contact the job superintendent. If the job superintendent receives a complaint, the superintendent shall investigate, take appropriate corrective actions, and report the action taken to the reporting party. Contract specifications shall be included in the Project's construction document. Lyons Avenue/Dockweiler Drive Extension Project 4.8 Noise SCH No. 2013082016 Page 4.8-22 City of Santa Clarita August 2017 4.8-4. All internal combustion engine construction equipment shall be properly muffled or equipped with other noise attenuating devices capable of achieving a sound attenuation of at least 3 dB(A) at 50 feet of distance. Such equipment shall also be in good working condition. 4.8-5. As feasible, construction activities shall use specially quieted equipment, such as electric air compressors and similar power tools, rather than diesel equipment. 4.8-6. Construction staging areas shall be located away from sensitive land uses, particularly away from the single-family properties on Aden Street, the single-family residences near Market Street and Race Street, and dormitories on the Master's University Campus. 4.8-7. Construction and grading activities shall be scheduled in such a way so as to avoid operating several pieces of equipment simultaneously, which causes high noise levels. 4.8-8. Construction activities whose specific location on the site may be flexible (e.g., operation of compressors and generators, cement mixing, general truck idling) shall be conducted as far as possible from the nearest noise -sensitive land uses, particularly away from single-family residences. 4.8-9. Temporary construction noise barriers of sufficient height shall be erected in such a way so as to disrupt line -of -sight between the active construction noise sources and any residences within 500 feet of the Project Site. 4.8.6 LEVEL OF SIGNIFICANCE AFTER MITIGATION With implementation of the mitigation measures recommended in this report, the noise levels associated with Project -related construction activities would be reduced; although, they would continue to either exceed City standards and/or cause an increase of at least 10 dBA Leq at the nearby residential areas. Therefore, this impact would continue to be significant and unavoidable regarding the exposure persons to or generation of noise levels in excess of standards established in the local general plan or noise ordinances, or applicable standards of other agencies, and the creation of a substantial temporary or periodic increase in ambient noise levels in the Project vicinity above levels existing without the Project. The Proposed Project's operational impacts would be less than significant prior to mitigation. Lyons Avenue/Dockweiler Drive Extension Project 4.8 Noise SCH No. 2013082016 Page 4.8-23 4. ENVIRONMENTAL IMPACT ANALYSIS 9. TRANSPORTATION AND TRAFFIC 4.9.1 INTRODUCTION The following section addresses the Proposed Project's impact on transportation and traffic based on the Traffic Study titled, Traffic Impact Analysis: Dockweiler Drive Alignment Project, Santa Clarita, CA, prepared by David Evans and Associates, dated August 8, 2017. The scope and methodology of this analysis was determined in conjunction with the City of Santa Clarita. The complete Traffic Study is included in Appendix H to this Draft EIR. The purpose of the Dockweiler Drive Alignment Project is to ascertain the feasibility of the General Plan alignment for Dockweiler Drive, which identifies the connection of Dockweiler Drive to Lyons Avenue at Railroad Avenue. The Project would extend Lyons Avenue from its existing terminus at Railroad Avenue on the west to future Master's University Master Plan Dockweiler extension to the east of railroad crossing consistent with the Circulation Element. This Project would include the consideration of a new at -grade rail crossing at Lyons Avenue and Railroad Avenue and includes the closure of the 13th Street rail crossing. 4.9.2 ENVIRONMENTAL SETTING Existing Conditions The City of Santa Clarita is one of the fastest growing cities in Los Angeles County. The City's General Plan includes several large developments in the area, and traffic volumes are expected to increase significantly. As such the City of Santa Clarita has identified a Project to extend Dockweiler Drive to Lyons Avenue. The proposed Dockweiler Drive Alignment Project is located in the City of Santa Clarita, approximately 35 miles northwest of the City of Los Angeles, within the Newhall community. Sierra Highway and the SR-14 (Antelope Valley) Freeway provide a boundary for the study area along the eastern side. Through traffic access on Placerita Canyon Road is restricted with a gate entrance west of Sierra Highway. Placerita Canyon Road currently is the primary connection to the Master's University and residents to the north. Newhall Avenue on the southern boundary of the study area provides a direct connection for cross valley traffic and connects Sierra Highway and Railroad Avenue. The UP/Metrolink Railroad line restricts access to the west with three existing at -grade railroad crossings located at 13th Street, Market Street, and Newhall Avenue. The extension of Lyons Avenue to Dockweiler Drive across the existing Metrolink line has been identified by the City as one of five key transportation projects. The alignment is part of the City's General Plan and consistent with the goals of the Old Town Newhall Specific Plan, Santa Clarita Valley Consolidated Traffic Model (SCVCTM), and the Compass Blueprint Plan. Lyons Avenue/Dockweiler Drive Extension Project 4.9 Transportation and Traffic SCH No. 2013082016 Page 4.9-1 City of Santa Clarita August 2017 Existing Street System Dockweiler Drive is designated as an east -west Secondary Highway from Sierra Highway to Railroad Avenue on the City of Santa Clarita Circulation Map Joint Highway Plan. The existing portion of Dockweiler Drive consists of one and two lanes in each direction with a landscaped median and limited parking throughout the study area. Dockweiler Drive is used as the primary access to single- and multi- family residences. State Route 14 Freeway (SR 14) provides regional access within the study area. The freeway is a four - lane (two in each direction) facility with interchange access at Placerita Canyon Road and Newhall Avenue. Lyons Avenue is designated as an east -west major highway west of Railroad Avenue and Secondary Highway east of Railroad Avenue on the City of Santa Clarita Circulation Map Joint Highway Plan. Three lanes in each direction are provided with traffic signals and left turn channelization at major intersections. Newhall Avenue is designated as a north -south secondary highway from Lyons Avenue to Railroad Avenue with one lane in each direction. From Railroad Avenue to SR-14, Newhall Avenue is designated as a major highway with three northbound lanes and three southbound lanes south of Railroad Avenue. Newhall Avenue roadway designation is identified on the City of Santa Clarita Circulation Map Joint Highway Plan. Railroad Avenue (formerly San Fernando Road) is a north -south major highway from Magic Mountain Parkway to Lyons Avenue and a secondary highway from Lyons Avenue to Newhall Avenue. This roadway provides two lanes in each direction and limited parking throughout the study area. Railroad Avenue roadway designation is identified on the City of Santa Clarita Circulation Map Joint Highway Plan. Sierra Highway is an old alignment of SR-14 from Los Angeles to Mojave. It is designated as a north - south major highway on the City of Santa Clarita Map Joint Highway Plan. It is a four lane (two in each direction) with traffic signals and left turn channelization at major intersections. Placerita Canyon Road is an east -west local roadway. This roadway provides a gate at the eastern entrance. The gate provides restrictive access to residents of the Placerita Canyon neighborhood. 13`h Street is an east -west unimproved local roadway. This roadway provides access to The Master's University and the Placerita Canyon neighborhood via its intersection with Railroad Avenue. One lane is provided in each direction. Lyons Avenue/Dockweiler Drive Extension Project 4.9 Transportation and Traffic SCH No. 2013082016 Page 4.9-2 City of Santa Clarita August 2017 Study Intersections A total of seventeen study intersections have been identified for analysis based on potential traffic impacts to the area roadways. Figure 4.9-1 shows the locations of the study intersections. The intersections identified for analysis are as follows: 1. Sierra Highway and SR-14 Freeway Southbound Ramps 2. Sierra Highway and Placerita Canyon Road 3. SR-14 Freeway Northbound Ramps and Placerita Canyon Road 4. Sierra Highway and Dockweiler Drive 5. SR-14 Freeway Southbound Ramps and Newhall Avenue 6.

Arch Street and 12a' Street/Placerita Canyon Road 17. Lyons Avenue and Dockweiler Drive (This intersection is a future intersection) Existing Intersection Conditions Existing Traffic Volumes As referenced from the City of Santa Clarita Circulation Element, Average Daily Traffic (ADT) is a measurement of the average number of vehicles that travel a segment of roadway during a 24-hour period. The ADT is a useful benchmark for determining roadway capacities. Figure 4.9-1 illustrates the existing street system ADT and intersection locations. Figure 4.9-2 illustrates the existing peak hour traffic volumes in the study area. As referenced from the City of Santa Clarita Circulation Element, Peak hour information, which is the highest volume of traffic to pass over a road in a one -hour period, allows for a more detailed method of evaluating traffic conditions along roadways and intersections, and is used whenever operational analysis is required. The traffic volume data used in the intersection capacity analysis were based on traffic counts conducted by Newport Traffic Studies, an independent traffic data collection company. Turn movement counts were collected during the AM (7-9 AM) and PM (4-6 PM) peak periods at the above -mentioned existing intersections identified for detailed analysis. These counts were conducted in December 2012. The resulting turning movement volumes are presented in the Intersection Capacity Analysis Appendix of the Traffic Study.

The analysis determines a level -of -service (LOS) which quantitatively describes the operating characteristics of signalized intersections and the maximum delay. The LOS ranges from "A" (the best) through "F" (system breakdown). The level -of -service is based on the average delay of vehicles at the intersections. Table 4.9-1 provides the LOS thresholds for signalized intersections per the HCM 2010 methodology.

For a TWSC the LOS is computed for each movement and the most critical LOS is the one that describes the effectiveness of that intersection, which is typically the stop controlled left turn movement from the minor street. For an AWSC intersection the LOS defines the whole intersection. Table 4.9-2 provides the LOS thresholds for TWSC and AWSC intersections. Table 4.9-2 HCM 2010 — LOS Criteria for 11WSC.

The level -of -service is based on the average delay of vehicles at the intersections. Table 49- 2 provides the LOS thresholds for roundabout intersections per the HCM 2010 methodology. The City of Santa Clarita preferred maximum acceptable level of service on arterial roads is LOS E. The City of Santa Clarity desired maximum acceptable level of service on residential neighborhood roads is LOS C or better.

This network provides mobility options to Santa Clarita Valley residents and businesses. Figure 4.9-4 illustrates the portion of the Santa Clarita Valley Circulation Plan bounded by the study area. A major component in the development of the Santa Clarita Valley is the inclusion of alternative travel modes and support facilities. These facilities include efficiency and capacity of existing systems, by promoting mixed -use development near transit facilities. Bicycle lanes and accessibility of bike paths are a fundamental component to a comprehensive transportation network. Figure 4.9-5 illustrates a portion of the Santa Clarita Valley's Bicycle Master Plan bounded by the study area. Opening Year (2019) Conditions Without Proposed Project A Project year of 2019 has been identified as the opening year for the Dockweiler Drive Alignment Project. A major factor in distribution of traffic is the anticipated growth within the study area due to development. The Year 2019 traffic volumes were provided by the City of Santa Clarita using the Santa Clarita Valley Consolidated Traffic Model (SCVCTM) for the Interim Year. It is to be noted that Other Area Projects anticipated to be constructed by Year 2019, have been incorporated into the SCVCTM, and account for expected growth. The Santa Clarita Valley Consolidated Traffic Model (SCVCTM) for Interim Year provided traffic volumes for the Project Year 2019 Condition. The model plots provided a No -Build Condition outlining the distribution of future traffic without the Project. The Project Year 2019 No -Build study intersections are provided in Figure 4.9-6 and the volumes are provided in Figure 4.9-7. The intersections were analyzed using the capacity analysis methodology described in the above. The analysis was conducted with the existing intersection geometries illustrated in Figure 4.9-8. The LOS for the study intersections presented in Table 4.9-4 represents the LOS for the critical movement. This is typically the stop controlled left turn from the minor street. As presented in Table 4.9-4 under Year 2019 No -Build Condition, most of the study intersections are anticipated to continue to operate at LOS E or better. There are four intersections that are anticipated to operate at LOS F, they are: Sierra Highway and SR-14 Southbound Ramps, Sierra Highway and Placerita Canyon Road, SR-14 Northbound Ramps and Placerita Canyon Road, and SR-14 Southbound Ramp and Newhall Avenue.

Future (2035) Conditions Without Proposed Project Future Year 2035 traffic volumes were provided by the City of Santa Clarita using the Santa Clarita Valley Consolidated Traffic Model (SCVCTM) for the Buildout Year. The model plots provided a No - Build Condition outlining the distribution of future traffic without the Project. The analysis of No -Build Condition utilizes the traffic volume projections for the City of Santa Clarita's traffic model together with the existing traffic flow data. It is to be noted that Other Area Projects anticipated to be constructed by Year 2035, have been incorporated into the SCVCTM, and account for expected growth. The buildout includes construction of future roadways Dockweiler Drive between Railroad Avenue and Valle Del Oro, Magic Mountain Parkway from railroad Avenue to Via Princessa, Via Princessa between Claibounzne Lane and Sheldon Avenue, and Santa Clarita Parkway. This also includes the proposed conceptual development of the North Newhall area (809 dwelling unit plus an approximate 11-acre commercial land use). The Future Year 2035 No -Build study intersections provided in Figure 4.9-9. the volumes provided in Figure 4.9-10. The intersections were analyzed using the capacity analysis methodology described above. The analysis was conducted with the Future Year 2035 No -Build Condition existing and mitigated study intersection geometries illustrated in Figure 4.9-11, Future Year 2035 No Build Intersection Configurations. The LOS for the study intersections presented in Table 4.9-5 represents the LOS for the critical movement. This is typically the stop controlled left turn from the minor street.

As discussed above, the LOS ranges from "A" (the best) through "F" (system breakdown). The level -of - service is based on the average delay of vehicles at the intersections. View Tables 4.9-1 and 4.9-2, for the LOS criteria for signalized intersections and unsignalized intersections, respectively. The City of Santa Clarita preferred maximum acceptable level of service on arterial roads is LOS E. The City of Santa Clarita desired maximum acceptable level of service on residential neighborhood roads is LOS C or better. Project Impacts Opening Year (2019) Conditions With Proposed Project The Santa Clarita Valley Consolidated Traffic Model (SCVCTM) for Interim Year provided traffic volumes for the Project Year 2019 with Proposed Project Condition. The model plots outlined the distribution of future traffic with the construction of the Proposed Project. The Project Year 2019 Proposed Project study intersections are provided in Figure 4.9-12, and the volumes provided in Figure 4.9-13. The analysis for the intersection of Arch Street/Dockweiler Drive and 12th Street/Placerita Canyon Road was conducted as a 5-leg all way stop controlled intersection. The analysis for the intersection of Lyons Avenue and Dockweiler Drive was conducted as a signalized intersection. The railroad crossing at the intersection of Railroad Avenue and 13th Street is proposed to be closed. The intersection will be modified, removing the northbound right turn lane and southbound left turn lane and restricting the eastbound through movement. The intersections were analyzed using the capacity analysis methodology described above. The analysis was conducted with the Project Year 2019 with Proposed Project existing and mitigated study intersection geometries illustrated in Figure 4.9-14. The LOS for the study intersections presented in Table 4.9-6 represents the LOS for the critical movement. This is typically the stop controlled left turn from the minor street. As presented in Table 4.9-6 under Year 2019 with Project Proposed Condition, most of the study intersections are anticipated to continue to operate at LOS E or better. There are four intersections that are anticipated to operate at LOS F, they are: Sierra Highway and SR-14 Southbound Ramps, Sierra Highway and Placerita Canyon Road, SR-14 Northbound Ramps and Placerita Canyon Road, SR-14 Southbound Ramps and Newhall Avenue. Mitigation measures are necessary to accommodate the anticipated Year 2019 traffic and reduce potential Project impacts. Lyons Avenue/Dockweiler Drive Extension Project 4.9 Transportation and Traffic SCH No. 2013082016 Page 4.9-20 City of Santa Clarita August 2017 With mitigation, the Sierra Highway and SR-14 Southbound Ramp intersection (Study Intersection 1) levels of service will increase to LOS B and LOS C during the AM and PM peak hours, respectively. With litigation. the Sierra Highway and Placenta Canyon Road intersection (Study Intersection 2) level of service will remain the salve at LOS C during the AM peak hour and will increase to LOS D during the PM peak hour. With mitigation. the SR-14 Northbound Ramps and Placerta Canyon Road intersection (Study Intersection 3) level of service will remain the same at LOS B during the AM peak hour and will increase to LOS B during the PM peak hour. With mitigation, the SR-14 Southbound Ramps and Newhall Avenue intersection (Study Intersection 5) levels of service will increase to LOS A during both AM and PM peak hours. With the implementation of the mitigation measures summarized at the end of this chapter, the Proposed Project's impacts dining the 2019 build -out year will be less than significant.

The model plots outlined the distribution of future traffic with the construction of the Proposed Project. The analysis of Proposed Project utilizes the traffic volume projections for the City of Santa Clarita's traffic model together with the existing traffic flow data. The traffic projections are based on the General Plan Buildout. The buildout includes construction of future roadways Dockweiler Drive between Railroad Avenue and Valle Del Oro„ Magic Mountain Parkway from Railroad Avenue to Via Princessa, and Via Princessa between Claibourne Lane and Sheldon Avenue. This also includes the proposed conceptual development of the North Newhall area (809 dwelling unit plus an approximate 11-acre commercial land use). The Future Year 2035 Proposed Project study intersections provided in Figure 4.9-15, the volumes provided in Figure 4.9-16. The intersections were analyzed using the capacity analysis methodology described above. The analysis was conducted with the Future Year 2035 Proposed Project Condition existing and mitigated study intersection geometries illustrated in Figure 4.9-17. The LOS for the study intersections presented in Table 4.9-7 represents the LOS for the critical movement. This is typically the stop controlled left turn from the minor street. As presented in Table 4.9-7 under Future Year 2035 with Proposed Project Condition, most of the study intersections are anticipated to continue to operate at LOS E or better. There are four intersections that are anticipated to operate at LOS F, they are: Sierra Highway and Placerita Canyon Road, Sierra Highway and Newhall Avenue, Valle Del Oro and Dockweiler Drive, and Main Street and Newhall Avenue. Mitigation measures are necessary to accommodate the anticipated Future Year 2035 traffic and reduce potential Project impacts. With mitigation, the Sierra Highway and Placerita Canyon Road intersection (Study Intersection 2) levels of service will increase to LOS D during both AM and PM peak hours. With mitigation, the Sierra Highway and Newhall Avenue intersection (Study Intersection 6) levels of service will increase from LOS E to LOS D during the AM peak hour and LOS F to LOS D during the PM peak hour. With mitigation, the Valle Del Oro and Dockweiler Drive intersection (Study Intersection 8) levels of service will increase to LOS C and LOS D during the AM and PM peak hours, respectively. With mitigation, the Main Street and Newhall Avenue intersection (Study Intersection 15) levels of service will increase from LOS F to LOS B during the AM peak hour and LOS E to LOS A during the PM peak hour. With the implementation of the mitigation measures summarized at the end of this chapter, the Proposed Project's impacts during the 2035 year will be less than significant.

The nearest Metrolink train station to the Proposed Project is the Jan Heidt Newhall Station located at Railroad Avenue and Market Street, approximately 0.25 mile south of Lyons Avenue. Currently the rail line serves approximately eight freight trains per day with thirty Metrolink commuter trains per weekday; twelve on Saturday and six trains Sunday. Passenger service from the Newhall station southbound to Los Angeles is provided by fourteen trains per weekday starting at approximately 5:00 AM and ending at 7:30 PM. Passenger service northbound to Lancaster from the Newhall station is also provided by nine trains starting at 7:00 AM until approximately 10:00 PM. Traffic Counts were compiled for the existing railroad crossings at 13's Street, Market Street. and Newhall Avenue. AM and PM peak hour traffic counts included the existing vehicles, pedestrians, and bicycle volumes. Table 4.9-8 presents the existing traffic counts. For a comparison of the No Build scenario and the Proposed Project scenario, Daily and AM and PM Peak hour traffic volumes were compiled for the Year 2019 and 2035 conditions as presented in Table 4.9-9 and Table 4.9-10. respectively.

Bicycle and Pedestrian Facilities The Califonva State Government Code outlines that a city must develop a Circulation Plan included in its General Plan that shall include the general location and extent of existing and proposed major thoroughfares, transportation routes, terminals and other local public utilities and facilities. Furthermore the City and County must coordinate with regional transportation plans. Regional plans affecting the Santa Clarita Valley included the California Department of Transportation (Caltrans) plan: the Regional Mobility Flan, prepared by the Southern California Association of Governments (SCAG); the Los Angeles Metropolitan Transportation Authority's (MTA or Metro) Congestion Management Program and bicycle way strategic plan; the Santa Clarita Transit's Transportation Development Plan (TDP); and the Los Angeles County's Airport Land Use Plan. Lyons Avenue/Dockweiler Drive Extension Project 4.9 Transportation and Traffic SCH No. 2013082016 Page 4.9-31 City of Santa Clarita August 2017 The Santa Clarita Valley's circulation system provides vital connections linking neighborhoods, services, and employment centers throughout the community and the region. A comprehensive transportation network of roadways, multi -use trails and bicycle paths, bus transit, and commuter rail provides mobility options to Valley residents and businesses. Planning for the ultimate location and capacity of circulation improvements will also enhance economic strength and quality of life in the Valley. Consideration to the Santa Clarita Valley's continued development of efficient, cost-effective and comprehensive transportation systems that are consistent with regional plans, and local needs. The Circulation Plan identifies and promotes a variety of techniques for improving mobility that go beyond planning for construction of new streets and highways. A major component in the development of the Santa Clarita Valley is the inclusion of alternative travel modes and support facilities. These facilities increase efficiency and capacity of existing systems, by promoting mixed -use development near transit facilities. Bicycle lanes and accessibility to bicycle paths are fundamental to a comprehensive transportation network. The Santa Clarita Valley's Bicycle and Pedestrian Facilities is provided in Figure 4.9-18. As illustrated in Figure 4.9-18, Potential Bike Lane connectors are proposed from Dockweiler Drive to connect to the Proposed Class I Bike Path along Railroad Avenue and the Proposed Class II Bike Path along Dockweiler Drive. Vehicle Miles Traveled California's Sustainable Communities and Climate Protection Act, also referred to as Senate Bill 375 (SB 375) became effective January 1, 2009. The goal of SB 375 is to help achieve AB 32's GHG emissions reduction goals by aligning the planning processes for regional transportation, housing, and land use. SB 375 requires CARB to develop regional reduction targets for GHGs, and prompts the creation of regional plans to reduce emissions from vehicle use throughout the state. California's 18 Metropolitan Planning Organizations (MPOs) have been tasked with creating "Sustainable Community Strategies" (SCS) in an effort to reduce the region's vehicle miles traveled (VMT) in order to help meet AB 32 targets through integrated transportation, land use, housing and environmental planning. On April 6, 2016, SCAG's Regional Council adopted the 2016-2040 Regional Transportation Plan/Sustainable Communities Strategy: Towards a Sustainable Future (2016-2040 RTP/SCS). The SCAG 2016 RTP/SCS is an update to the 2012-2035 RTP/SCS that further integrates land use and transportation in certain areas so that the region as a whole can grow smartly and sustainably. Between 2015 and 2040, the SCAG region is anticipated to experience increases in population, households and jobs. The 2016 RTP/SCS includes land use strategies, based on local general plans, as well as input from local governments, to achieve the AB 32 state -mandated reductions in GHG emissions through decreases in regional per capita VMT. As part of the 2016-2040 RTP/SCS, transportation network improvements would be included, and more compact, infill, walkable and mixed -use development strategies to accommodate new region's growth would be encouraged to accommodate increases in population, households, employment, and travel demand.

C LASS 1 BIKEPATH r PARKER Figure 4.9-18 ENVIRONMENTAL CONSULTANTS Santa Claiita Valley's Existing Bicycle and Pedestrian Facilities City of Santa Clarita August 2017 The Proposed Dockwelier Drive Extension Project is identified as one of the financially constrained projects within the RTP/SCS, as shown in Appendix B, 2016 RTP/SCS Project List.' As such, the project is recognized as part of the regional strategy that is consistent with SCAG's policies to reduce VMTs. The Proposed Project is also identified in the City's Circulation Element as an addition route of travel connecting Lyons Avenue to Dockweiler Drive. Because no new land uses are being proposed, the Proposed Project would not generate any new vehicle trips and thus would not have the potential to increase VMTs on a per capita basis. 4.9.4 CUMULATIVE IMPACT Development of the Proposed Project in conjunction with the related projects would increase the amount of traffic in the Proposed Project area within the City of Santa Clarita. Cumulative traffic impacts are addressed by comparing the Existing Conditions as presented in the "Environmental Setting" portion of this Section, to the Future with Project for 2019 and 2035 (which includes the Proposed Project plus ambient and related project growth), as presented in the "Project Impacts" portion of this Section. As discussed under "Project Impacts," the Proposed Project would not result in a significant impact at any of the analyzed intersections in the study area with the incorporation of mitigation measures. With respect to traffic from each of the related projects, mitigation measures for each related project would be implemented individually in coordination with the Lead Agency. The Proposed Project would not result in a significant impact related to traffic, emergency access, design hazards, or alternative modes of transportation that currently serve the Project area. With respect to each of these areas, the design of each related project would be evaluated individually in coordination with the appropriate Lead Agency department to minimize any potential impacts. Overall, the Proposed Project's cumulative transportation and traffic impacts would be less than significant. 4.9.5 MITIGATION MEASURES Year 2019 Project Mitigation Measures 4.9-1 Dockweiler Drive extension: Construct to full Secondary Highway Pavement width, from Aden Avenue to west of Valle Del Oro, providing two lanes eastbound (uphill) and one lane westbound (downhill), as necessary.

INTRODUCTION In addition to the environmental impact categories analyzed in detail in the DEIR, the City of Santa Clarita has determined that the development and operation of the Proposed Project would not result in potentially significant impacts to the environmental impact topics listed below. Section 15128 of the CEQA Guidelines states: "An EIR shall contain a statement briefly indicating the reasons that various possible significant effects of a project were determined not to be significant and were therefore not discussed in detail in the EIR. Such a statement may be contained in an attached copy of an Initial Study. " It has been determined that there is no evidence that the Proposed Project would cause significant environmental effects in the following areas and that no further environmental review of these issues is necessary for the reasons described below. Agricultural Resources The California Department of Conservation, Division of Land Protection, lists Prime Farmland, Unique Farmland, and Farmland of Statewide Importance under the general category of "Important Farmland." The Extent of Important Farmland Map Coverage maintained by the Division of Land Protection indicates that the Project Site is not included in the Important Farmland category.' In addition, locally the Project Site is zoned for a mix of commercial and residential uses and not "agricultural" uses. Therefore, the Proposed Project would not result in the conversion of Prime Farmland, Unique Farmland, or Farmland of Statewide Importance to a non-agricultural use. Additionally, there are no known Williamson Act Contract agreements associated with the Project Site. The Project Area contains the following land use and zoning designations: "SP(3)" (Old Town Newhall Specific Plan) and MXN (Mixed Use Neighborhood). Therefore, the Project site would have no impact associated with the conversion of agricultural uses or forested lands. No further analysis of this issue is required. Greenhouse Gas Emissions On August 28, 2012, the City of Santa Clarita adopted a Climate Action Plan (CAP), which provides policies and identifies actions intended to reduce GHG emissions within the City and assist in the fight against Climate Change. Overall the goal of the CAP is to reduce Santa Clarita's community -wide GHG emissions below the 2005 baseline emissions by 2020. The CAP includes a set of strategies the City can use to reduce the amount of greenhouse gas emissions produced in the community. Implementation of the measures proposed in the Proposed CAP would result in an annual community -wide reduction in Source: State of California Department of Conservation, Division of Land Resource Protection, Farmland Mapping and Monitoring Program, Los Angeles County Important Farmland Map, 2002 Los Angeles Area Map. Lyons Avenue/Dockweiler Drive Extension Project 5.1 Impacts Determined to be Less Than Significant SCH No. 2013082016 Page 5.1-1 City of Santa Clarita August 2017 GHG emissions of approximately 193,000 MTCO2e by 2020 from local measures and an additional reduction of approximately 148,952 MTCO2e by 2020 from statewide measures. This would reduce GHG emissions from the Business -as -usual projections for 2020 by 17 percent and would exceed the GHG reduction targets of 16 percent established by CARB in its revised scoping plan. Implementation of the strategies identified in the CAP would also exceed the City's goal to reduce 2020 GHG emissions to a level below the 2005 GHG emissions baseline by 4 percent. The CAP defines a local threshold of significance for green house gas emissions (GHG) for project level submittals that are subject to environmental review under CEQA. Goals, objectives and policies approved under the General Plan are forecast to meet the GHG emission reduction targets mandated by AB 32. Therefore, development projects that are able to demonstrate consistency with the General Plan and zoning ordinance are by association consistent with the CAP and are not subject to further environmental review. Development proposals that are not consistent with the City's General Plan and/or Unified Development Code (Zone Changes/General Plan Amendments) must demonstrate a 12 percent reduction in the GHG emissions from the Controlled 2020 Business as Usual Scenario, to be deemed consistent with the CAP. Development proposals that are not consistent with the City's General Plan and/or Unified Development Code and that can not demonstrate a 12 percent reduction in GHG emissions from the Controlled Business as Usual Scenario shall be deemed to have a significant impact on GHG emissions. The Project is consistent with the Circulation Element of the General Plan and will not require a zone change or General Plan amendment. As such, the Project's potential to generate GHGs will be less than significant with respect to consistency with all applicable plans, policies or regulations adopted for the purpose of reducing the emissions of greenhouse gases, and no further analysis of this issue is warranted. Hazards and Hazardous Materials A significant impact may occur if a project involves the use or disposal of hazardous materials as part of its routine operations which may have the potential to generate toxic or otherwise hazardous emissions that could adversely affect sensitive receptors. Since the Project would not require the transport, use, and/or disposal of potentially hazardous materials, the potential for an impact to occur is considered low. In addition, California Government Code Section 65962.5 requires various state agencies to compile lists of hazardous waste disposal facilities, unauthorized releases from underground storage tanks, contaminated drinking water wells and solid waste facilities from which there is known migration of hazardous waste and submit such information to the Secretary for Environmental Protection on at least an annual basis. No properties within or immediately adjacent to the Project site appear on the State's list of hazardous materials sites. Therefore, further analysis of this issue is not warranted. Mineral Resources There are no known economic mineral resources located beneath the Project Site. The Project Site is not within a known source area for aggregate or other mineral resources. Additionally, the Project Site is not located in an area of potential petroleum resources. Therefore, development of the Proposed Project would not result in the loss of availability of a known mineral resource that would be of value to the Lyons Avenue/Dockweiler Drive Extension Project 5.1 Impacts Determined to be Less Than Significant SCH No. 2013082016 Page 5.1-2 City of Santa Clarita August 2017 region and the residents of the state. In addition, development of the Proposed Project would not result in the loss of availability of a locally important mineral resource recovery site. As the Proposed Project would not result in any potentially significant impacts to mineral resources, no further analysis of this issue is warranted. Population and Housing The Project involves the buildout of a proposed roadway alignment that was identified within the City's Circulation Element of the General Plan. No residential, commercial, or industrial land uses are proposed. Therefore, the Project would not have the potential to induce substantial population growth in the area. As such, the Proposed Project would not significantly impact the existing housing stock. Additionally, the Project would not displace any existing housing units, necessitating the construction of replacement housing elsewhere. Therefore, no impact would occur and no further analysis is required. Public Services (Fire and Police Protection, Schools, Parks, Libraries, and other Public Facilities) Fire and Police Protection A significant impact may occur if the County of Los Angeles Fire Department (LACoFD) and Los Angeles County Sherriffs Department (LASD) could not adequately serve the areas affected by the Project's circulation plan based upon response time, access, or fire hydrant/water availability. The Project would not directly increase the demands for fire and police protection as the Project does not include any new housing units or commercial uses. Emergency access to the Placerita Canyon community would be facilitated through the Project's alignment, which is consistent with the City's adopted Circulation Element. The Project's alignment would be an improvement to the current access route into the Placerita Canyon community via 13a' Street. The potential upgrade or closure of the 13a' Street at -grade crossing is a proposed safety feature aimed at reducing potential conflicts between pedestrians, vehicles and trains. The Project's impact upon fire and police services would be less than significant and no further analysis is warranted. Schools There are no residential properties on the Project Site and none are planned as part of the development of the Proposed Project. Therefore, development of the Proposed Project would not result in a direct increase in the resident population or in any associated school -aged children. Therefore, with respect to local schools, no impact would occur and no further analysis of this issue is warranted. Parks There are no residential properties on the Project Site and none are planned as part of the development of the Proposed Project. Therefore, development of the Proposed Project would not result in a direct increase in the resident population that would use park facilities. Therefore, no impacts on local parks would occur and no further analysis of this issue is warranted. Lyons Avenue/Dockweiler Drive Extension Project 5.1 Impacts Determined to be Less Than Significant SCH No. 2013082016 Page 5.1-3 City of Santa Clarita August 2017 Libraries As the Proposed Project does not include residential or commercial uses, no new residents or employees would utilize existing library services in the project area. Therefore, impacts on local libraries as a result of the development of the Proposed Project would not occur. No further analysis of this issue is warranted. Other Public Facilities Proposed Project operations would utilize and, to some extent, affect the maintenance of public roads. However, wear and tear on City streets resulting from project -related traffic is not expected to be excessive or beyond normal requirements. Furthermore, the City would be required to implement roadway improvements (including any required street repairs due to any relocation of public utilities, project construction damage, and traffic mitigation measures), as monitored and enforced by the City. Therefore, impacts to public facilities as a result of the development of the Proposed Project would be less than significant. No further analysis of this issue is warranted. Recreation The Proposed roadway alignment does not include the development of new residential or commercial uses. As such, the Proposed Project will not directly impact existing recreation facilities such that substantial physical deterioration of the facilities would occur or be accelerated in the existing neighborhood, regional parks or other recreational facilities. Therefore, no further analysis of this issue is warranted. Utilities The Proposed Project includes the development of a roadway alignment. The Proposed Project does not include the development of residential, commercial or industrial uses. As such the Proposed Project would not require any connections to a sanitary sewer. Thus, no impact to wastewater treatment facilities would be created. The drainage system of the Project will be developed so that post development peak runoff discharge rates are equal to or less than pre development peak runoff rates, as required by the City of Santa Clarita and the Countywide MS4 Permit. As such, the Project would not result in the construction of new stormwater drainage facilities or expansion of existing facilities. The Project would not create a demand for potable water or for solid waste resources. Therefore impacts associated with the Proposed Project, with respect to utilities, would be less than significant and no further analysis is warranted. Lyons Avenue/Dockweiler Drive Extension Project 5.1 Impacts Determined to be Less Than Significant SCH No. 2013082016 Page 5.1-4 5. GENERAL IMPACT CATEGORIES 117,1\ 1.10 M-05 I zlx 1 I-v Section 15126.2(b) of the State CEQA Guidelines requires that an EIR describe any significant environmental impacts which cannot be avoided. Specifically, Section 15126.2(b) states: "Describe any significant impacts, including those which can be mitigated but not reduced to a level of insignificance. Where there are impacts that cannot be alleviated without imposing an alternative design, their implications and the reasons why the project is being proposed, notwithstanding their effect, should be described. " Based on the analysis contained in Section 4.0. Environmental Impact Analysis, of this Draft EIR, implementation of the Proposed Project would result in significant and unavoidable environmental impacts associated with the following environmental issues: • Construction air quality (localized PM10 and PM2 5 emissions); • Construction related noise impacts. As discussed in greater detail in Section 4.2, Air Quality, the Proposed Project would result in significant localized air emissions in close proximity to residential land uses within 100 meters of the Project Site on a temporary and intermittent basis during construction. Localized NOx and CO emissions would be below the significance thresholds at all sensitive receptor locations. However, localized thresholds would be exceeded for PM,o and PM2 5 emissions at two locations: (1) the single family residential land uses located immediately north of the Project Site (within a proximity of 100 meters) and (2) the residential land uses within 100 meters south of the Project Site in the vicinity of Market Street and Race Street. Localized emissions would be below the stated thresholds for any land use located further than 100 meters from the Project Site. Therefore, localized air quality impacts resulting from construction activities would be considered significant and unavoidable. As discussed in greater detail in Section 4.8, Noise, the Proposed Project's construction noise impacts would exceed the maximum allowable exterior noise levels. Thus, the Proposed Project's construction noise impacts would be considered a significant impact on a short term and intermittent basis during the construction period. Lyons Avenue/Dockweiler Drive Extension Project 5.2 Significant Unavoidable Impacts SCH No. 2013082016 Page 5.2-1 5. GENERAL IMPACT CATEGORIES Section 15126.2(c) of the State CEQA Guidelines states that the "uses of nonrenewable resources during the initial and continued phases of the project may be irreversible since a large commitment of such resources makes removal or nonuse thereafter unlikely. Primary impacts and, particularly, secondary impacts (such as highway improvement which provides access to a previously inaccessible area) generally commit future generations to similar uses.... Irretrievable commitments of resources should be evaluated to assure that such current consumption is justified." IRREVERSIBLE ENVIRONMENTAL CHANGES The Project would necessarily consume limited, slowly renewable and non-renewable resources, resulting in irreversible environmental changes. This consumption would occur during construction of the Project and would continue throughout its operational lifetime. The development of the Project would require a commitment of resources that would include: (1) building materials; (2) fuel and operational materials/resources; and (3) the transportation of goods and people to and from the Project Site. Construction of the Project would require consumption of resources that are not replenishable or which may renew so slowly as to be considered non-renewable. These resources would include certain types of lumber and other forest products, aggregate materials used in concrete and asphalt (e.g., sand, gravel and stone), metals (e.g., steel, copper and lead), petrochemical construction materials (e.g., plastics), and water. Fossil fuels, such as diesel, gasoline and oil, would also be consumed in the use of construction vehicles and equipment. The commitment of resources required for the type and level of proposed development would limit the availability of these resources for future generations for other uses during the operation of the Project. However, the consumption of natural resources associated with the Project would be of a relatively small scale and would be consistent with regional and local growth forecasts in the City of Santa Clarita and the Southern California region as a whole. Therefore, although irreversible environmental changes would result from the Project, such changes would be considered less than significant. SECONDARY IMPACTS To the extent the Project has the potential to result in secondary impacts to the environment, those impacts are addressed within the environmental impact analyses contained within Sections 4.1 through 4.9 of this Draft EIR. The extension of the proposed roadway (Lyons Avenue) was designated as a Secondary Highway per the City of Santa Clarita's General Plan. While the project is anticipated to have localized impacts with respect to air quality and construction noise, the construction of this roadway segment will reduce "cross valley" trip lengths and travel times, provide an alternate travel route and support a multi -modal "Complete Street" transportation network by reducing bus travel times in the City. Completion of this gap will also serve an increase in bike and pedestrian traffic, as well as close a vital gap in these facilities leading to the Newhall Metrolink station. The resultant decrease in congestion and encouragement of active transportation modes will have an enriching effect on the environment by Lyons Avenue/Dockweiler Drive Extension Project 5.3 Significant Irreversible Environmental Changes SCH No. 2013082016 Page 5.3-1 City of Santa Clarita August 2017 decreasing vehicle related pollutants and thereby improving community health and the quality of life. As such, secondary impacts associated with utilities and public services would be less than significant. Lyons Avenue/Dockweiler Drive Extension Project 5.3 Significant Irreversible Environmental Impacts SCH No. 2013082016 Page 5.3-2 5. GENERAL IMPACT CATEGORIES C�113�1ii� �L11i [!J i►l iZ,X"_ j Section 15126.2(d) of the State CEQA Guidelines requires a discussion of the ways in which a proposed project could be growth -inducing. This would include ways in which the project would foster economic or population growth, or the construction of additional housing, either directly or indirectly, in the surrounding environment. Section 15126.2(d) requires an EIR to: "Discuss the ways in which the proposed project could foster economic or population growth or the construction of additional housing, either directly or indirectly, in the surrounding environment. Included in this are projects that would remove obstacles to population growth (a major expansion of a wastewater treatment plant might, for example, allow for more construction in service areas). Increases in the population may further tax existing community service facilities so consideration must be given to this impact. Also discuss the characteristic of some projects which may encourage and facilitate other activities that could significantly affect the environment, either individually or cumulatively. It must not be assumed growth in any area is beneficial, detrimental, or of little significance to the environment. " This project is part of the City of Santa Clarita's proposed 10 year plan to upgrade the city road network, as presented in the City's General Plan. This project would meet the anticipated demand for improved traffic circulation resulting from the growth of the City. The extension of Dockweiler Drive from between 12th Street through the Master's University to the existing Dockweiler Drive roadway has been designated as a 4-lane secondary highway in the City's General Plan. Currently, Dockweiler Drive extends from Sierra Highway near State Route 14 and terminates approximately 0.8 miles to west near Valle Del Oro and Lyons Avenue extends from I-5 to Railroad Avenue. This proposed segment of the Lyons Avenue / Dockweiler Drive connection serves as a critical link in one of the City's major east -west arterial highways. The City of Santa Clarita is one of the fastest growing cities in Los Angeles County. The City's General Plan Circulation Element includes the subject project. This roadway segment and its extension have been re -designated as a 4-lane secondary highway in the City's updated General Plan. The existing local roadway network including Newhall Avenue, Sierra Highway, State Route 14, and Interstate 5, cannot accommodate the forecasted increase in cross -valley traffic. As such, the City's adopted General Plan identifies a future Dockweiler Drive connection to Railroad Avenue as a needed roadway to accommodate future traffic levels. Lyons Ave / Dockweiler Drive improvements will provide this vital link by implementing a new east -west connection and will function as a Complete Streets corridor. The only other east -west roadway in the vicinity is Newhall Avenue which experiences significant peak -hour congestion. This results in increased motorist travel times, difficulty in keeping transit services on -time, delays in emergency vehicle response times (including wildfire suppression), and traffic safety concerns. Newhall Avenue is a heavily traveled corridor, exceeding 43,000 in daily traffic volumes as of April 2013. The current Level of Service (LOS) for the intersection of Newhall Avenue and Lyons Avenue is Lyons Avenue/Dockweiler Drive Extension Project 5.4 Growth Inducing Impacts SCH No. 2013082016 Page 5.4-1 City of Santa Clarita August 2017 LOS C during the AM peak hour and LOS D in the PM peak hour. If the proposed project is not built, the daily traffic volumes are anticipated to exceed 56,000 with the LOS for this intersection projected to be LOS E in the PM peak hour. The Proposed Project will provide a second east -west arterial and benefits all types of vehicular traffic (commuters, transit goods movement, and emergency responders) as an alternate to Newhall Avenue, ultimately reducing the peak hour delay from 115 to 75 vehicle -hours (a difference of 45 vehicle -hours) per day. The Santa Clarita General Plan envirions several large developments in the area, and as such traffic volumes have the potential to increase significantly. The project is intended to serve as a major east -west corridor link segment in the area and to facilitate access to existing and planned development. The proposed segment of Dockweiler Drive must be improved to ultimate width prior to the City's build out (year 2030 and beyond) according to Santa Clarita's General Plan (adopted June 26, 1991 and amended in December 1997 and June 2011). With Construction of the Project„ this segment of the Lyons Avenue/Dockweiler Drive extension will connect with Lyons Avenue west of the railroad and to Dockweiler. Construction of the proposed roadway segment will reduce "cross valley" trip lengths and travel times, provide an alternate travel route and support a multi -modal "Complete Street" transportation network by reducing bus travel times in the City. Completion of this gap will also serve an increase in bike and pedestrian traffic, as well as close a vital gap in these facilities leading to the Newhall Metrolink station. The resultant decrease in congestion and encouragement of active transportation modes will have an enriching effect on the environment by decreasing vehicle related pollutants and thereby improving community health and the quality of life. Thus the Proposed Project would accommodate the planned and anticipated growth within the City and would not create or induce substantial growth -inducing impacts that have not already been accounted for within the City's General Plan.

PROJECT ALTERNATIVES i►Y�Z�111i��1-1I[��►1 Pursuant to CEQA Guidelines Section 15126.6(a), an EIR is required to describe a range of reasonable alternatives to the project, or to the location of the project, which would feasibly attain most of the basic objectives of the project but would avoid or substantially lessen any of the significant effects of the project, and evaluate the comparative merits of the alternatives. The discussion of alternatives need not be exhaustive, but rather it must consider a reasonable range of potentially feasible alternatives that will foster informed decision -making and public participation. An EIR must also evaluate a "no project" alternative. An EIR is not required to consider alternatives that are infeasible. Analytical Assumptions and Methodology The level of detail required in the alternatives analysis does not need to be as detailed as required for the environmental analysis of the Proposed Project. Rather, an EIR should include "sufficient information about each alternative to allow meaningful evaluation, analysis, and comparison with the proposed project." As such, the alternatives analysis is presented as a comparative qualitative and quantitative analysis to the Proposed Project, and assumes that all applicable mitigation measures proposed for the Proposed Project would apply to each alternative. Impacts associated with each alternative are evaluated in comparison to the Proposed Project's impacts and are classified as increased, reduced, or essentially equivalent to the level of impact associated with the Proposed Project. Alternatives Considered But Rejected From Further Study CEQA Guidelines Section 15126.6(b) states that "the discussion of alternatives shall focus on alternatives to the project or its location which are capable of avoiding or substantially lessening any significant effects of the project, even if these alternatives would impede to some degree the attainment of the project objectives, or would be more costly." Thus, the consideration of feasible alternatives was focused on lessening or avoiding the Project's significant unavoidable impacts associated with air quality and construction noise and vibration. In accordance with CEQA Guidelines Section 15126.6(c), there were three alternative alignments that were considered by the Lead Agency but rejected as infeasible during the scoping process. The alternatives considered but rejected included (1) connecting Dockweiler Drive to Railroad Avenue via Market Street (2) extending Lyons Avenue to Dockweiler Drive with a bridge over the railroad right-of- way, and (3) extending Lyons Avenue to Dockweiler Drive with a below grade underpass under the railroad right-of-way. The physical constraints associated with each of these alternatives that led to them being rejected without further evaluation are addressed below. Lyons Avenue/Dockweiler Drive Extension Project 6.1 Introduction SCH No. 2013082016 Page 6.1-1 City of Santa Clarita August 2017 Market Street Alignment The Dockweiler Drive to Market Street alignment was considered as another option that would indirectly connect Dockweiler Drive to Lyons Avenue without resulting in an additional at -grade crossing. Under this alternative alignment, Dockweiler Drive would connect to Railroad Avenue via Market Street as shown in Figure 6.1-1, Market Street Alignment. This alignment would indirectly connect to Lyons Avenue via Railroad Avenue, Main Street, Walnut Street or Newhall Avenue. This alternative was rejected from further consideration due to the resulting 11.15% gradient of the roadway profile resulting from the existing topographical gradient between Market Street and Dockweiler Drive, the relatively sharp curve at the base of an include where the alignment would connect to Market Street. A gradient of 11.15% would not meet the street standards of a secondary highway and would potentially result in unsafe roadway conditions. Additionally, Market Street is a local residential street that directly abuts and provides access to single and multi -family residential land uses. The proposed alignment of Dockweiler Drive through this existing residential neighborhood would not be consistent with the alignment identified within the Circulation Element and would not be compatible with respect to public safety and local residential street standards. For this reason, this alternative alignment was rejected as infeasible. Lyons Avenue Overpass Extension to Dockweiler Drive The Lyons Avenue Overpass Extension to Dockweiler Drive was considered as a potential option to provide a direct connection from Lyons Avenue to Dockweiler Drive without an at -grade crossing. An illustration of the Lyons Avenue connection to Dockweiler Drive with an overpass crossing Railroad Avenue and the railroad right-of-way is shown in Figure 6.1-2, Lyons Avenue Overpass Alignment. As shown in Figure 6.1-2, Lyons Avenue starts ascending at the Chestnut Street / Lyons Avenue intersection at a 5% slope, passes above Railroad Avenue, the railroad tracks and Newhall Creek, and descends at a 5% grade to touch down on the existing ground approximately 600' east of the creek. Lyons Avenue would need an overhead bridge over Railroad Avenue, the railroad tracks, and Newhall Creek. In order to provide sufficient vertical clearance for the passing trains, Lyons Avenue will be raised approximately 30' above the railroad tracks. Two connections via Walnut Street / 9 b Street and Walnut Street / I I b Street between Lyons Avenue and Railroad Avenue will be established to replace the existing intersection.

S­ D—d E— & A—, I-- May 2017 PARKER Figure 6.1-2 ENVIRONMENTAL CONSULTANTS Lyons Avenue Overcrossing City of Santa Clarita August 2017 With respect to traffic circulation, the existing configuration of a direct intersection connection between Lyons Avenue and Railroad Avenue could not be kept for all of the grade separation alternatives. In order to maintain traffic circulation between the two major streets, two connector roads, one on each side of Lyons Avenue, would have to be established. Although the connection between the two major roads could be re-established, traffic would need to make additional turning movements to go from one street to another. This new configuration will provide unnecessary delays and will create congestion within the area. Different utilities such as sewer, water, gas, found within Lyons Avenue and Railroad Avenue would need to be relocated and/or abandoned. In order to build a grade separation with an overhead crossing, most of the utilities within the construction limits would be impacted and would need to be relocated at a significant cost. With respect to impacts upon Newhall Elementary School, as shown in Figure 6.1-2, the southeast corner of Newhall Elementary School might be impacted by the reconfiguration of Walnut Street and 1 la' Street for the grade separation option. Walnut Street and 1 la' Street, which would be the necessary link between Lyons Avenue and Railroad Avenue for the grade separation, would have heavier traffic than their current configuration and this might potentially pose a risk to the nearby school route. In regards to community impacts, most of the properties adjacent to Lyons Avenue, Walnut Street, 9 b Street and I I b Street, shown as pink shading on Figure 6.1-2, would be fully acquired for the grade separation option due to change of grade on Lyons Avenue and loss of access routes. The adjacent residents and businesses would be relocated. In addition, the grade separation option is not consistent with the City's Old Town Newhall Specific Plan. The grade separation will divide the community and cause an unnecessary burden to the residents within the impacted area. Additionally, raising Lyons Avenue over Railroad Avenue, the railroad tracks, and Newhall Creek would physically bisect the existing Newhall community and create a disconnect to the properties on either side of Lyons Avenue. Especially for residents living south of Lyons Avenue, it would require more effort to get to the Old Town Newhall Library on the north side of Lyons Avenue. The front view of the library would be blocked by a retaining wall supporting the roadway embankment of the grade separation. Additionally, 24 parking stalls in the library parking lot would be lost due to the necessary widening on Railroad Avenue for the grade separation. Because this alternative would be disruptive to the existing established community of Old Town Newhall and for the reasons addressed above, this alternative was rejected from further consideration. Lyons Avenue Underpass Extension to Dockweiler Drive The Lyons Avenue Underpass Extension to Dockweiler Drive was considered as another alternative to provide a direct connection from Lyons Avenue to Dockweiler Drive without an at -grade crossing. An illustration of the Lyons Avenue connection to Dockweiler Drive with an underpass crossing Railroad Avenue, the railroad right-of-way, and Newhall Creek is shown in Figure 6.1-3, Lyons Avenue Underpass.

M PARKER Figure 6.1-3 ENVIRONMENTAL I.ONSOLTANTS Lyons Avenue Undercrossing City of Santa Clarita August 2017 Street intersection at a 5% slope and goes beneath Railroad Avenue, the railroad tracks and Newhall Creek. After the new lowered Lyons Avenue passes below Newhall Creek, it starts ascending to existing ground level approximately 1,100' east of the creek. A roadway bridge for Railroad Avenue, a railroad bridge for railroad tracks and a water bridge for the creek are needed for the underpass. In order to maintain enough vertical clearance from the underpass to the soffits of the bridges, the underpass near the railroad tracks will be approximately 28' below the existing ground. To maintain traffic circulation between Lyons Avenue and Railroad Avenue, two loop connectors via Walnut Street and I Vh Street to the north, and Walnut Street and 9th Street to the south, will be needed. Minor streets such as Main Street will be cul-de-sacs at Lyons Avenue. For the underpass alternative, a bridge to carry storm water from Newhall Creek would be required so the lowered Lyons Avenue could pass underneath. However, Newhall Creek is a natural flood control channel, instead of a man-made water channel such as the California Aqueduct whose flow volume is controlled. The amount of storm water flowing though the bridge would be hard to predict. If a larger storm occurred than the bridge could handle, the underpass would be flooded and traffic would be interrupted. Moreover, the bridge or the underpass would be susceptible to damage during storm events. Similar to the overpass alternative described above, the underpass alternative would be equally disruptive to the existing established community with respect to traffic circulation, relocation of utilities, impacts to Newhall Elementary School, and community disruption as described above for the Lyons Avenue overcrossing alternative. Therefore, for these reasons the underpass alternative was rejected from further consideration. Selection of Alternatives The objective of the project alternatives analysis, as directed by CEQA, is to identify alternatives that could feasibly attain most of the basic objectives of the project but would avoid or substantially lessen any of the significant effects of the project, and evaluate the comparative merits of the alternatives. Based on this directive, the Project Alternatives evaluated within the scope of this EIR are as follows: 1. No Project Alternative; 2. Alternative 1 (Proposed Alignment With Improvements at the 13th Street Rail Crossing); and 3. Alternative 2 (Proposed Alignment to Arch Street Without Lyons At -Grade Crossing). A detailed description and environmental analysis for each of these alternatives is provided within Section 6.2 through Section 6.4 The identification of the alternative that would be most capable of reducing the Proposed Project's adverse environmental impacts is presented in Section 6.5, Environmentally Superior Alternative. Lyons Avenue/Dockweiler Drive Extension Project 6.1 Introduction SCH No. 2013082016 Page 6.1-7 6. PROJECT ALTERNATIVES The No Project Alternative is the circumstance under which the Proposed Project does not proceed. CEQA Guidelines (Section 15126.6(e)) provides that the "no project" analysis shall discuss the existing conditions at the time the Notice of Preparation is published, as well as what can reasonably be expected to occur in the foreseeable future if the project is not approved based on current plans and consistent with available infrastructure and community services. A Notice of Preparation (NOP) was prepared by the City of Santa Clarita and distributed to the State Clearinghouse, Office of Planning and Research, responsible agencies, and other interested parties on August 5, 2013. The Project Site consists of improved segments of Railroad Avenue and Lyons Avenue roadways and undeveloped land to the east extending towards The Master's University and Arch Street. The west end of the Project Site encompasses portions of Newhall Creek and traverses a storage yard utilized by Los Angeles County Department of Public Works. The portion of the Project Site that includes the intersection of Railroad Avenue and 13'b Street is developed with existing road surface and an at -grade crossing. The UP/Metrolink Railroad line crosses the Project Site east of the intersection of Railroad Avenue and Lyons Avenue Railroad and at the intersection of Railroad Avenue and 13'b Street. The proposed road alignments are located on the alluvial flood plain and hillside areas adjacent to Newhall Creek. The Project Site is covered with light to moderate growth of natural grasses and chaparral. Under the No Project Alternative, the Project Site would remain in its current state, as no roadway extension would occur from Lyons Avenue to Dockweiler Drive and Arch Street. The 13'b Street at -grade crossing would remain open. ENVIRONMENTAL ANALYSIS Aesthetics The existing visual character of the Project Site would temporarily change from construction -related activities during the duration of the construction period of the Proposed Project. This impact would be considered significant but temporary. Additionally, upon completion of the Proposed Project, the aesthetic character of the Project Site and its immediate surroundings would be permanently altered as the Proposed Project would result in the permanent and irreversible grading and re -contouring of the westernmost segment of the ridgeline. The No Project Alternative would not involve any new construction or demolition associated with the Proposed Project. No improvements or physical modifications would occur and the Project Site would remain in its present form. Therefore, views of the Proposed Project would remain unchanged (for existing views of and from the Project Site refer to Figures 2-2, 12.3, 2.4, 2.7 and 2.8 in Section 2, Project Description, as well as Figures 4.1-2 and 4.1-3 in Section 4.1, Aesthetics). Additionally, the No Project Alternative would not alter any ridgelines in the Project Site vicinity, would not result in the loss of oak trees, and would retain the existing sources of lighting and glare on the Project Site and in the surrounding area. Since the No Project Alternative Lyons Avenue/Dockweiler Drive Extension Project 6.2 No Project Alternative SCH No. 2013082016 Page 6.2-1 City of Santa Clarita August 2017 includes no physical alterations to the current site, the No Project Alternative would have no impact when compared to the Proposed Project. Air Quality Construction Construction -related emissions and their associated air quality impacts for the Proposed Project would be short-term in nature and limited only to the period when construction activity is actively taking place. The Proposed Project's construction emissions would be below SCAQMD's significance thresholds for all criteria pollutants. The No Project Alternative would not create any construction emissions, as grading, demolition and construction activities would not occur. The No Project Alternative would have no impact when compared to the Proposed Project with respect to air quality during the construction phase. Operation No operational air pollutant emissions are generated at the Project Site as the Project Site does not contain any buildings and consist largely of undeveloped land and road surface. Although the Proposed Project would not directly generate any new vehicle trips, the Proposed Project would result in changes to the traffic circulation in the vicinity and would alter the average daily traffic volumes and peak hour traffic volumes at local intersections. The similar utilization of the Project Site as compared to existing conditions would create similar air pollution emissions from mobile sources from existing roadways. The No Project Alternative would not violate any air quality standards. Compared to existing conditions, the No Project Alternative would result in no increased air quality impacts. The No Project Alternative would have reduced air quality impacts when compared to the Proposed Project. Biological Resources Construction -related activities, particularly site clearing, grading, and the implementation of the road surface, could have adverse effects on plant and wildlife habitat, and together, would be considered a significant impact. With implementation of mitigation measures, impacts from the Proposed Project would reduce these construction -related impacts to a less than significant level. Portions of the Project Site that are undeveloped and contain plant and wildlife habitat would be left undistributed by the No Project Alternative, as no development would occur. Therefore, no impact would occur with respect to biological resources under the No Project Alternative. Cultural Resources Historic Resources As no cultural or historic habitable structures are located on -site, similar to the Proposed Project, the No Project Alternative would not have the potential to adversely impact any historic or cultural resources. Lyons Avenue/Dockweiler Drive Extension Project 6.2 No Project Alternative SCH No. 2013082016 Page 6.2-2 City of Santa Clarita August 2017 Archaeological Resources Construction -related earthwork activities may result in the accidental discovery of prehistoric or historic archaeological resources or Native American burial sites. Implementation of mitigation measures would reduce impacts resulting from the Proposed Project to a less than significant level. As the No Project Alternative would not involve any earthwork or ground disturbing activities no adverse impacts would occur to archaeological resources. Paleontological Resources The Proposed Project includes construction -related earthwork activities may result in the accidental discovery of paleontological resources. Implementation of mitigation measures would reduce impacts resulting from the Proposed Project to a less than significant level. The No Project Alternative would not involve any earthwork or ground disturbing activities. As such there would be no potential for any adverse impacts to occur to paleontological resources. Tribal Cultural Resources The No Project Alternative would not involve any earthwork or ground disturbing activities. As such there would be no potential for any adverse impacts to occur to tribal cultural resources. Geology and Soils Under the No Project Alternative, the Project Site remains in its current condition and no new construction of any infrastructure would occur. As such, the No Project Alternative would not result in any new sources or increased risk of loss, injury, or death involving strong seismic ground shaking, liquefaction, landslides, or ground failure on -site. The No Project Alternative would have no impact to geology and soils. When compared to the Proposed Project, the No Project Alternative would have a reduced impact upon potential geotechnical hazards. Hydrology And Water Quality The Proposed Project would be required to prepare and implement a SWPPP prior to earthwork activities that will put best management practices and erosion control measures to prevent pollution in stormwater discharge. Additionally, in accordance with NPDES requirements, the Project Applicant would be required to have a Project -specific SUSMP in place during the operational life of the Project to address the management of runoff from the proposed roadway extension. Therefore, water quality impacts during the Project's construction and operation would be less than significant. The Proposed Project would also span the Newhall Creek. Roadway construction would include a new bridge across Newhall Creek and provide embankment protection to the roadway and creek. Under the No Project Alternative, the Project Site remains in its current condition and no new construction of any infrastructure would occur. As such, the No Project Alternative would not result in any impacts to water quality or substantially alter the existing drainage pattern of the site or area, including through the alteration of the course of a stream or river, or substantially increase the rate or Lyons Avenue/Dockweiler Drive Extension Project 6.2 No Project Alternative SCH No. 2013082016 Page 6.2-3 City of Santa Clarita August 2017 amount of surface runoff in a manner which would result in flooding on- or off -site. When compared to the Proposed Project, the No Project Alternative would have a reduced impact upon water quality and inundation and flooding. Land Use and Planning Under the No Project Alternative, the Project Site would experience no changes in land uses or changes to the condition of the Project Site. The Project Site includes four land use categories that guide development on -site defined by the General Plan. Since the No Project Alternative would result in no changes to the current land use and zoning designations or to the physical condition of the Project Site, the No Project Alternative would have no impact to land use and planning. The extension of Dockweiler Drive is identified in the Circulation Element as a major new roadway. The extension would provide a connection from Railroad Avenue to Sierra Highway. Therefore, the No Project Alternative would be inconsistent with the Circulation Element. However, compared to the Proposed Project, the No Project Alternative would result in a reduced impact with regards to land use and planning as no permits or approvals would be required. As compared to the Proposed Project, which would require an Oak Tree Removal Permit for the removal of two oak trees and a Hillside Development Permit, the No Project Alternative would not require any land use approvals or entitlements. As such land use and zoning impacts would be less than significant. Noise Construction Construction of the Proposed Project would require the use of heavy equipment for ground clearing, site grading, and roadway construction. Several pieces of construction equipment operating simultaneously would generate a noise level of approximately 94.6 dBA. The estimated construction noise levels impacting sensitive receptors are expected to exceed the City's daytime noise standards for residential uses (see Table 4.8-3). The construction noise levels would therefore constitute a significant impact. The No Project Alternative would involve no new construction. As such, no construction noise or vibration is anticipated to occur under this alternative. Under the No Project Alternative, impacts with respect to construction noise or vibration would be reduced as compared to the Proposed Project. Operation The Proposed Project is anticipated to alter roadway traffic volumes as the Proposed Project would create a new roadway segment connecting Lyons Avenue to Dockweiler Drive. Locations in the vicinity of the Project Site could experience slight changes in noise levels as a result of the change in traffic patterns. The No Project Alternative would not introduce any new activities to the Project Site with the potential to create operational noise impacts or sensitive receptors with the potential to be impacted by noise impacts. Operation noise on -site would be consistent with existing uses on -site. Under the No Project Alternative, no increased impact would occur with respect to operational noise. Impacts with respect to operational noise would be reduced when compared to the Proposed Project's less than significant impact. Lyons Avenue/Dockweiler Drive Extension Project 6.2 No Project Alternative SCH No. 2013082016 Page 6.2-4 City of Santa Clarita August 2017 Transportation and Traffic The Traffic Report analyzed sixteen intersections for existing year conditions (2014), opening year conditions (2019), and future year conditions (2035). Potential Project traffic impacts were found for opening year conditions and future year conditions. With the incorporation of the mitigation measures identified in Section 4.9, Traffic and Transportation, potential traffic impacts associated with the Proposed Project would be reduced to a less than significant level. Opening Year (2019) Conditions Without Proposed Project The Santa Clarita Valley Consolidated Traffic Model (SCVCTM) for Interim Year provided traffic volumes for the Project Year 2019 Condition. The model plots provided a No -Build Condition outlining the distribution of future traffic without the Project. The Project Year 2019 No -Build study intersections provided in Figure 4.9-6, the volumes provided in Figure 4.9-7. The intersections were analyzed using the capacity analysis methodology described in Section 4.9. The analysis was conducted with the existing intersection geometries illustrated in Figure 4.9-8. The LOS for the study intersections presented in Table 4.9-4 represents the LOS for the critical movement. This is typically the stop controlled left turn from the minor street. As presented in Table 4.9-4 under Year 2019 No -Build Condition, most of the study intersections are anticipated to continue to operate at LOS E or better. There are four intersections that are anticipated to operate at LOS F, they are: Sierra Highway and SR-14 Southbound Ramps, Sierra Highway and Placerita Canyon Road, SR-14 Northbound Ramps and Placerita Canyon Road, and SR-14 Southbound Ramp and Newhall Avenue. Future (2035) Conditions Without Proposed Project Future Year 2035 traffic volumes were provided by the City of Santa Clarita using the Santa Clarita Valley Consolidated Traffic Model (SCVCTM) for the Buildout Year. The model plots provided a No - Build Condition outlining the distribution of future traffic without the Project. The analysis of No -Build Condition utilizes the traffic volume projections for the City of Santa Clarita's traffic model together with the existing traffic flow data. It is to be noted that Other Area Projects anticipated to be constructed by Year 2035, have been incorporated into the SCVCTM, and account for expected growth. The buildout includes construction of future roadways Dockweiler Drive between Railroad Avenue and Valle Del Oro, Magic Mountain Parkway from Railroad Avenue to Via Princessa, Via Princessa between Claibourne Lane and Sheldon Avenue, and Santa Clarita Parkway. This also includes the proposed conceptual development of the North Newhall area (809 dwelling unit plus an approximate 11-acre commercial land use). The Future Year 2035 No -Build study intersections are provided in Figure 4.9-9 and the volumes are provided in Figure 4.9-10. The intersections were analyzed using the capacity analysis methodology described above. The analysis was conducted with the Future Year 2035 No -Build Condition existing and mitigated study intersection geometries illustrated in Figure 4.9-11, Future Year 2035 No Build Intersection Configurations. The LOS for the study intersections presented in Table 4.9-5 represents the LOS for the critical movement. This is typically the stop controlled left turn from the minor street. As Lyons Avenue/Dockweiler Drive Extension Project 6.2 No Project Alternative SCH No. 2013082016 Page 6.2-5 City of Santa Clarita August 2017 presented in Table 4.9-5 under Future Year 2035 No -Build Condition, several intersections are anticipated to operate at LOS F, these intersections are: Sierra Highway and SR-14 Southbound Ramps, Sierra Highway and Placerita Canyon Road, SR-14 Northbound Ramps and Placerita Canyon Road, SR- 14 Southbound Ramps and Newhall Avenue, Sierra Highway and Newhall Avenue, Newhall Avenue and Lyons Avenue, and Main Street and Newhall Avenue. Railroad Crossing Analysis For a comparison of the No Build scenario and the Proposed Project scenario, Daily and AM and PM Peak hour traffic volumes were compiled for the Year 2019 and 2035 conditions as presented in Table 4.9-9 and Table 4.9-10, respectively. As presented in Table 4.9-9 under Project Year 2019, the total average daily traffic is anticipated to be highest for the No Build Condition. As presented in Table 4.9-10 under Project Year 2035, the total average daily traffic is anticipated to be highest for the Proposed Project. Therefore, when compared to the Proposed Project, the No Project Alternative would have an increased impact to railroad crossings for the 2019 conditions as compared to the Proposed Project. Bicycle and Pedestrian Facilities The No Project Alternative would be inconsistent with the Santa Clarita Valley's Bicycle and Pedestrian Facilities map, which is provided in Figure 4.9-18. As illustrated in Figure 4.9-18, Potential Bike Lane connectors are proposed from Dockweiler Drive to connect to the Proposed Class I Bike Path along Railroad Avenue and the Proposed Class I Bike Path along Railroad Avenue. Lyons Avenue/Dockweiler Drive Extension Project 6.2 No Project Alternative SCH No. 2013082016 Page 6.2-6 6. PROJECT ALTERNATIVES 3. ALTERNATIVE 1 (PROPOSED ALIGNMENT WITH THE 13TH STREET RAIL CROSSING) Similar to the Proposed Project, the Alternative 1 Project would involve the development of the proposed roadway alignment and associated infrastructure, which would include a new at -grade crossing and a secondary east -west arterial roadway connecting Lyons Avenue to the proposed Dockweiler Drive extension that would connect Dockweiler Drive to a new five -leg intersection at the Arch Street/12'b Street/Placerita Canyon intersection. The Alternative 1 Project differs from the Proposed Project by leaving the existing at -grade crossing at the intersection of 13'b Street and Railroad Avenue as is instead of removing the crossing, as proposed by the Proposed Project. The proposed alignment of Dockweiler Drive under Alternative 1 is illustrated in Figure 6.3-1. Figure 6.2-2 provides an aerial photograph depicting the existing configuration of the at -grade railroad crossing at 13'b Street and Railroad Avenue, which will remain in its current configuration without any future improvements. Similar to the Proposed Project, the intersection of Arch Street, 12'b Street, Placerita Canyon and Dockweiler Drive would be improved with one of three intersection design configurations. For an illustration of the proposed design configurations, see Figure 2-11, Option A - 5-Legged Intersection (Option A), Figure 2-12 - Option B — Traffic Circle, and Figure 2-13 — Option C - 3-Legged Intersection, respectively, in Section 2.0, Project Description.' 1 It should be noted that Figures 2-11, 2-12 and 2-13 are referred to for purposes of illustrating the three potential intersection configurations at the Arch Street/121h Street/Placerita Canyon/Dockweiler Drive intersection. Those figures show the closure of the 131h Street railroad crossing and intersection at Railroad Avenue, which would be retained in its current configuration under Alternative 1. Lyons Avenue/Dockweiler Drive Extension Project 6.3 Alternative 1 SCH No. 2013082016 Page 6.3-1 4 •T � a s RQ d A i wAT GRADERAILROAD C-. 4 s �- 'tER EXrENsrQ,ry �.�, NETT SALE .. _ rw City of Santa Clarita August 2017 ENVIRONMENTAL ANALYSIS Aesthetics Temporary Construction Impacts The Alternative 1 Project would similarly impact existing views and aesthetic character of the area by grading, stockpiles or debris and soil, building materials and construction equipment, all of which could occupy the field of view of passing motorists, pedestrians and nearby residents. The construction site would continue to be visible from the residential properties on Aden Avenue and from passing motorists on Lyons Avenue, Railroad Avenue, Market and Race Streets, and at the Arch Street/12th Street/Placerita Canyon intersection with the development of the Alternative 1 Project. Thus, the existing visual character of the approximate 5-acre Project Site would be adversely impacted throughout the duration of the construction period. Therefore, impacts related to aesthetic character of the area during construction would be the same as compared to the Proposed Project, where impacts would be considered significant but temporary. Implementation of Mitigation Measure 4.1-1 would also be recommended for the Alternative 1 Project. Long Term Operational impacts Upon completion of the Alternative 1 Project the aesthetic character of the Project Site and its immediate surroundings would be permanently altered. Views of the intersection at Lyons Avenue and Railroad Avenue will be altered, as the Proposed Project includes re -profiling the intersection of Lyons Avenue and Railroad Avenue to allow the construction of a new SCRRA/Union Pacific railroad at -grade crossing east of Railroad Avenue and the addition of a new bridge crossing Newhall Creek. Views of the intersection of Lyons Avenue and Railroad Avenue and the hillside on the southeast portion of the Project Site will be altered by grading for the proposed roadway alignment. Views of the Project Site at the intersection of Railroad Avenue and 13th Street would be similar to existing views of the intersection, since the Alternative 1 Project includes the improvement of the at -grade railroad crossing. Like the Proposed Project, the roadway extension would be developed in accordance with the City's roadway standards and design guidelines to ensure the graded hillsides, medians, and walkways are landscaped in a manner that maintains the visual aesthetic quality and character of the City's roadway infrastructure. Therefore, impacts related to long-term operation would be the same as compared to the Proposed Project, which would have a less than significant impact. Similar to the Proposed Project, Alternative 1 would require an oak tree permit for the loss of two oak trees that are located within the proposed grading limits and right-of-way alignment and a Hillside Review Permit for the grading of an existing hillside. Approval of the Oak Tree Permit and Hillside Review Permit would reduce aesthetic impacts to less than significant levels. Lyons Avenue/Dockweiler Drive Extension Project 6.3 Alternative 1 SCH No. 2013082016 Page 6.3-4 City of Santa Clarita August 2017 Alteration of A Significant Ridgeline Similar to the Proposed Project, construction of the proposed roadway alignment under Alternative 1 will permanently alter a significant ridgeline as designated in the City of Santa Clarita General Plan. However, as noted in Section 4.1, Aesthetics, the eastern segment of the Dockweiler alignment was previously approved under a separate project entitlement for The Master's University in 2009, which included a Ridgeline Alteration Permit for the eastern segment of this ridgeline.2 As part of the approved entitlements for The Master's University Master Plan in 2009, the irreversible grading and re -contouring of the ridgeline was approved to the western limit of the Master's University Campus. As shown in Figure 4.1-1, the grading limits of the Proposed Project would retain the gradual elevation profile of the base of the ridgeline leading to the Master's University Campus. Limited views of the altered portion of the ridgeline within the Proposed Project limits would be partially visible from the public rights -of -way along Market Street and Race Street to the south of the Project Site. As a project design feature the grading plan incorporates landform grading practices to blend the manufactured slopes and required drainage benches into the natural topography to the maximum extent feasible. Plant materials will be utilized to protect slopes from slippage and soil erosion and minimize the visual effects of grading and construction on a hillside area. With incorporation of the project design features to develop and improve a new roadway extension that is consistent with the City's roadway design standards, the Proposed Project would result in a less than significant impact with respect to the loss of an aesthetic natural feature. Therefore, impacts related to the loss of a significant ridgeline would be the same as compared to the less than significant impact anticipated for the Proposed Project. With approval of a Hillside Review Permit, aesthetic impacts associated with the grading of Alternative 1 would be reduced to less than significant levels. Visual Character Similar to the Proposed Project, the Alternative 1 Project would not introduce buildings or development that would block existing views or substantially degrade the visual character of the existing site. The Alternative 1 Project also includes pedestrian, equestrian, and bicycle improvements to Dockweiler Drive that would include wide sidewalks, Class II bike lanes on each side, and a multi -purpose trail on the east side. Class II bike routes will provide a striped lane for one-way bike travel and will be marked with signs and pavement striping. Multi -purpose trails are to be unpaved and will be available for equestrian, hiking, and mountain bike use. These project features would increase accessibility to scenic natural resources including the Newhall Creek and surrounding ridgelines and mountains. Therefore, impacts related to visual character would be less than significant. Roadway Light and Glare Ambient nighttime lighting for the Alternative 1 Project would be similar to that of the Proposed Project. The Alternative 1 Project would introduce nighttime lighting to the Project Area, which will include pole - mounted street lights at intersections, bollards along Dockweiler Drive, flashing safety lighting for the proposed at -grade crossing, and would contribute to additional light and glare from the headlights of z Ibid. Lyons Avenue/Dockweiler Drive Extension Project 6.3 Alternative 1 SCH No. 2013082016 Page 6.3-5 City of Santa Clarita August 2017 vehicles utilizing the roadway. Lighting associated with the Alternative 1 Project uses is not anticipated to substantially impact any surrounding sensitive uses as the street lights would be installed with downward directional fixtures and would not create light trespass onto any adjacent properties. Light emanating from the Alternative 1 Project would be a relatively low-level indirect source of light illuminating the roadway and pedestrian walkways and would not adversely impact other properties in the immediate area. Additionally, the steep terrain and orientation of the southeastern portion of the Project Site would shield vehicle headlights, signage lighting and street lights from impacting the residential properties within the Placerita Canyon community to the east and along Market and Race Streets to the west. Overall, the Alternative 1 Project would be expected to slightly increase ambient lighting in the area, but compliance with the design standards and requirements established in the Santa Clarita Municipal Code Section 17.51.050 would mitigate lighting impacts to a less than significant level. Therefore, impacts related to roadway light and glare would be less than significant. Air Quality Construction Construction of the Alternative 1 Project would occur over an approximately 12-month timeframe and would involve clearing, grading, excavation, trenching, and asphalt paving. Similar to the Proposed Project, construction of the Alternative 1 Project would require 4,990 cubic yards (cy) of cut, 2,760 cy of fill, and 2,230 cy of soil export associated with grading and excavation. Sources of emissions during construction include: stationary and mobile uses of construction equipment, construction vehicles (heavy- duty construction vehicles and worker vehicles), and energy use. Additionally, earthwork and construction activities would generate fugitive dust emissions. These construction -related emissions and their associated air quality impacts would be short-term in nature and limited only to the period when construction activity is actively taking place. The Alternative 1 Project's construction emissions would be below SCAQMD's significance thresholds for all criteria pollutants. Therefore, the Alternative 1 regional construction air quality emissions would be less than significant. AQMP Consistency The Alternative 1 Project would not exceed the AQMD's significance thresholds for regional construction emissions and thus would not increase the frequency or severity of existing air quality violations or cause or contribute to new air quality violations within the Basin. The Alternative 1 Project is consistent with the AQMP and would not interfere with attainment of air quality levels identified in the AQMP. Similar to the Proposed Project, the Alternative 1 Project would help reduce congestion and vehicles per miles travelled by providing sidewalks and bicycle lanes and by providing direct access from the residential area and Master's University area to the Jan Heidt Newhall Metrolink Station and Old Town Newhall. The Alternative 1 Project encourages alternative modes of transportation other than motor vehicles and would be consistent with the goals and objectives of the AQMP to reduce vehicle emissions throughout the Basin. Lyons Avenue/Dockweiler Drive Extension Project 6.3 Alternative 1 SCH No. 2013082016 Page 6.3-6 City of Santa Clarita August 2017 Localized Construction Emissions Similar to the Proposed Project, the Alternative 1 Project would result in significant localized air emissions in close proximity to residential land uses within 100 meters of the Project Site on a temporary and intermittent basis during construction. Localized NOx and CO emissions would be below the significance thresholds at all sensitive receptor locations. However, localized thresholds would be exceeded for PM10 and PM2.5 emissions at two locations: (1) the single family residential land uses located immediately north of the Project Site (within a proximity of 100 meters) and (2) the residential land uses within 100 meters south of the Project Site in the vicinity of Market Street and Race Street. Localized emissions would be below the stated thresholds for any land use located further than 100 meters from the Project Site. Therefore, notwithstanding implementation of mitigation measures 4.2-1 through 4.2-4, localized air quality impacts resulting from construction activities would be considered significant and unavoidable. Operational Emissions Although the Alternative 1 Project would not directly generate any new vehicle trips, it would result in changes to the traffic circulation in the vicinity and would alter the average daily traffic volumes and peak hour traffic volumes at local intersections. A CO hotspot analysis was conducted for the Proposed Project, and as the Alternative 1 Project is within the same envelope as the Proposed Project, it was found that, under worst -case conditions, future CO concentrations at each intersection would not exceed the state 1- hour and 8-hour standards with or without the development of the Proposed Project. Therefore, no significant project -related impact would occur relative to future carbon monoxide concentrations of the Alternative 1 Project. The Alternative 1 Project would have a less than significant impact with respect to this criterion. Biological Resources Habitat Modification Vegetation The Alternative 1 Project Site grading plans for the roadway extension of Lyons Avenue to Dockweliler drive to the south, and Arch Street to the north, would be identical to the Proposed Project. The grading plans indicate that within the Project Site 2.32 acres of vegetation would be removed (100 percent of the vegetation resources present). Of the vegetation communities impacted Disturbed California Sagebrush - California Buckwheat Scrub is the dominant plant community present by area and approximately 0.63 acre of this habitat would be lost through site grading and project implementation. The loss of 2.32 acres of vegetation is considered adverse; although, due to the Site's disturbance history, its small size, the lack of sensitive plant communities, the lack of structure for wildlife, and high percentage of invasive and non- native plant species generally associated with disturbed areas, impacts associated with the loss of 2.32 acres of vegetation present on -site is considered less than significant. Similar to the Proposed Project, this alternative would require the removal of two oak trees, which would be considered a significant impact under both the City of Santa Clarita and CEQA. Replacement oak trees would be planted in the Lyons Avenue/Dockweiler Drive Extension Project 6.3 Alternative 1 SCH No. 2013082016 Page 6.3-7 City of Santa Clarita August 2017 number necessary to comply with the requirements stipulated in the Oak Tree Permit issued by the City. With approval of the required oak tree permits, and implementation of Mitigation Measure 4.3-7, impacts upon the loss or pruning of any oak tree would be reduced to less than significant levels. Wildlife Similar to the Proposed Project, construction activity and grading operations of the Project Site for the Alternative 1 Project would disturb and/or threaten the survival of common wildlife species present on - site. It is expected that species of low mobility, particularly small mammals, amphibians, and reptiles, would be lost during site preparation, grading, and construction. Site grading and project implementation would eliminate approximately 2.32 acres of natural habitat present on -site, and would result in an incremental reduction in native wildlife species abundance and diversity. However, due to nearby urban development and the associated human disturbance, field investigations indicate wildlife diversity and abundance on the Project Site is relatively low. Most the species of mammals, birds, and reptiles observed on -site or thought to occur on -site are relatively common. Project implementation is not expected to cause current wildlife population of common species on or adjacent to the Project Site to drop below self- sustaining levels. Therefore, impacts to common wildlife species are not considered significant. Project -related activities associated with site preparation and construction could result in the direct loss of individuals of one special -status wildlife species (the silvery legless lizard) and of active nests or the abandonment of active nests by adult birds should grading occur during nesting season. The loss of a California species of special concern and active bird nests would be a considered significant without mitigation. Implementation of mitigation measures 4.3-2 and 4.3-3 would reduce impacts to the silvery legless lizard and nesting birds to a less than significant level. Federally Protected Wetlands Based on field investigations, two CDFW jurisdictional features occur within the Project Site, the Newhall Creek and a small ephemeral drainage that is a tributary to Newhall Creek. There is also a small area of narrow -leaf willow thicket, which probably does not qualify as a Federally jurisdictional wetland. The Alternative 1 Project would result in both temporary and permanent impacts to the areas of the Newhall Creek and its associated tributary and are classified as "riverine and related permanent water, with continuous flow at least seasonally." With the implementation of MM 4.3-3, impacts to jurisdictional resources would be reduced to a less than significant level. Wildlife Movement and Corridors The Project Site for Alternative 1 is generally surrounded on three sides by development and road networks. However, Newhall Creek does extend through the Site and provides passage through developed areas between the Santa Clarita River and the Angeles National Forest to the southeast and is considered a part of a wildlife movement or migration corridor. To limit impacts to wildlife movement, four 25-foot wide and 8-foot deep openings in a concrete box bridge with 80-foot wide soft base and 2:1 protected side slopes is proposed where the proposed roadway extension crosses Newhall Creek. As designed, this bridge would not result in any barrier to wildlife movement and would serve to protect Newhall Creek as Lyons Avenue/Dockweiler Drive Extension Project 6.3 Alternative 1 SCH No. 2013082016 Page 6.3-8 City of Santa Clarita August 2017 a functioning wildlife movement corridor. The Alternative 1 Project as proposed would not result in significant impacts to wildlife movement. Construction Activity Construction -related activities, particularly site clearing, grading, and the implementation of the road surface, could have adverse effects on plant and wildlife habitat, and together, would be considered a significant impact. Implementation of Mitigation Measure 4.3-4 would reduce these construction -related impacts to a less than significant level. Operation Increase in Populations of Non -Native Species Non-native plants and wildlife are expected to increase on -site, because these species are more adapt to urban environments and can out -compete native species. Historical and ongoing development in the vicinity of the Project Site has already supported continual and ongoing increase and proliferation of non- native plant and wildlife species in the vicinity of the Project Site. Development of the Alternative 1 Project is not expected to substantially increase the distribution of non-native plants and wildlife. With compliance to the mitigation measure 4.3-5, Project impacts would be less than significant. Increased Light and Glare It is anticipated that nighttime lighting would increase in areas adjacent to the Project Site, which can disturb breeding and foraging behavior, movement, and can potentially alter breeding cycles of birds, mammals, and nocturnal invertebrates. Because of surrounding development around the Project Site, nearby natural areas already receive some nighttime lighting. The Alternative 1 Project would increase light and glare effects near to the Newhall Creek corridor. Implementation of mitigation measure 4.3-6 would decrease this impact to a less than significant level. Stormwater and Urban Runoff Similar to the Proposed Project, it is expected that stormwater runoff from the Alternative 1 Project would be limited to pavement runoff during periodic storm events. It is reasonable to assume runoff could substantially affect special -status species potentially occurring downstream from the Project Site (i.e. Newhall Creek), incrementally diminish habitat, and degrade the quality of the environment. With the compliance to City's standard stormwater requirements and required design criteria, impacts to Newhall Creek resulting from Stormwater runoff would be less than significant. Cultural Resources Cultural and Historic Resources No cultural or historic habitable structures are located on -site, and as such, the Alternative 1 Project would not have the potential to adversely impact any historic or cultural resources. Lyons Avenue/Dockweiler Drive Extension Project 6.3 Alternative 1 SCH No. 2013082016 Page 6.3-9 City of Santa Clarita August 2017 Archaeological Resources No known archeological sites are identified within the Project Site for the Alternative 1 Project. While, portions of the Project Site are improved with roadways, the Alternative 1 Project will consist of earthwork activities, such as grading and excavation, in areas that are currently undeveloped. Construction -related earthwork activities may result in the accidental discovery of prehistoric or historic archaeological resources or Native American burial sites. Implementation of mitigation measures 4.4-1 will reduce impacts to a less than significant level. Paleontological Resources The records search conducted by the Vertebrate Paleontology Department of the Natural History Museum of Los Angeles County yielded no known fossil localities within the Project Site. The closest vertebrate fossil localities are from the Saugus Formation, located directly north of the Proposed Project Site. While it is possible that fossilized materials may be discovered during site preparation and construction, specifically grading and excavation activities, precautionary measures set forth in mitigation measure 4.4- 2 would reduce any potential adverse impacts to paleontological resources to a less than significant level. Tribal Cultural Resources Similar to the Proposed Project, Alternative 1 would not have a direct impact upon known tribal cultural resources. Nevertheless, provisions for the identification and evaluation of accidentally discovered archeological resources would be implemented in accordance with mitigation measure 4.4-1. With the incorporation of mitigation measure 4.4-1, impacts upon tribal resources would be less than significant. Geology And Soils The Project Site is underlain by Saugus Formation, Pacoima Formation, Quaternary alluvium and artificial fill and has historic high groundwater elevations greater than 50 feet in depth. The Project Site is located in the State of California Seismic Hazard Zone map for the Newhall Quadrangle. Hazards related to seismic -related ground failures (including ground rupture and liquefaction) are considered low. All slopes should be evaluated by the Project Geotechnical engineer at the planning and design stages. The hillside area of the site is designated on the State of California Seismic Hazard Zone Map to have earthquake -induced slope instability. No landslides have been mapped on the Project Site. Remedial measures will be required where ascending or descending cut slopes are not stable as determined by geologic or geotechnical stability analyses. The potential for earthquake -induced slope failures is considered low provided that future geologic and geotechnical evaluations and recommendations for slope stability is incorporated into design and construction. Additionally, specific recommendations for design and construction should be provided to address soil stability, including: hydro -compression, expansive soils, rippability, the handling of oversized material, soil corrosivity, shirking and bulking of materials, and the handling of the need for retaining wall. Lyons Avenue/Dockweiler Drive Extension Project 6.3 Alternative 1 SCH No. 2013082016 Page 6.3-10 City of Santa Clarita August 2017 No oil wells have been drilled on or immediately adjacent to the Project Site. If any undocumented oil wells are encountered during future construction operations at the site, their location(s) should be surveyed and the current well conditions evaluated. Water wells have been drilled in the vicinity of the proposed road alignments. If one of these water well is within the proposed road alignment, or if a water well is encountered during future construction operations at the site, the location should be surveyed and the potential impacts to well conditions should be evaluated. The implementation of mitigation measure 4.5-1 would insure that potential Alternative 1 Project impacts would be reduced to a less than significant level. Hydrology And Water Quality Construction During the construction phase, the typical pollutants that affect surface water quality are: sediment from soil erosion, petroleum products (gasoline, diesel, kerosene, oil and grease), hydrocarbons from asphalt paving, construction equipment leaks, paints and solvents, detergents, fertilizers, and pesticides. Similar to the Proposed Project, the Alternative 1 Project would be required to prepare and implement a SWPPP prior to earthwork activities that will put best management practices and erosion control measures to prevent pollution in stormwater discharge. All project construction activities would comply with the City's grading permit regulations, which require the implementation of grading and dust control measures, including a wet weather erosion control plan if construction occurs during rainy season, as well as inspections to ensure that sedimentation and erosion is minimized. Therefore, through compliance with NPDES requirements and City grading regulations, the Alternative 1 Project's construction impacts related to water quality would not violate any water quality standards or waste discharge requirements or otherwise substantially degrade water quality. Construction -related impacts to hydrology and water quality would therefore be less than significant. Operation Once the Alternative 1 Project has been constructed, urban runoff could include the aforementioned contaminants, trace metals, landscape maintenance debris, dry product spills, and "nuisance flows" from landscape irrigation during the dry -season. In accordance with NPDES requirements, the Project Applicant would be required to have a Project -specific SUSMP in place during the operational life of the Project to address the management of runoff from the proposed roadway extension. The SUSMP would include site design, source control, low -impact development, and best management practices. Therefore, implementation of the storm water quality plan would reduce water quality impacts during the Alternative 1 Project's operation to less than significant. Inundation and Flooding A post -Project hydraulic model was analyzed for the Proposed Project to understand the impacts of inundation and flooding. The result of the post -Project hydraulic model indicate that the proposed bridge and channel improvements can accommodate the Capital Flood and will not create any flood hazard for the adjacent railroad and proposed street improvements. Riprap and vegetation linings are recommended Lyons Avenue/Dockweiler Drive Extension Project 6.3 Alternative 1 SCH No. 2013082016 Page 6.3-11 City of Santa Clarita August 2017 for the high and moderate shear zones, respectively. As the Alternative 1 Project is generally the same as the Proposed Project, with respect to the roadway extension from Lyons Avenue to Dockweiler Drive to the south and Arch Street to the north, the same aforementioned conclusions and recommendations are applicable to the Alternative 1 Project. Land Use And Planning Implementation of the Alternative 1 Project would not disrupt or physically divide an established community. Monument signage will properly guide traffic and identify the entrance to the Placerita Canyon community as a residential community with no through access. Additionally, similar to the Proposed Project, the Alternative 1 Project will provide increased pedestrian and vehicular access in the area. The Alternative 1 Project would not conflict with any applicable land use plans, policies, or regulations, including: the Regional Transportation Plan / Sustainable Communities Strategy, City of Santa Clarita Municipal Code, City of Santa Clarita General Plan (including the Circulation Element), the Placerita Canyon Special Standards District and North Newhall Area, Old Town Newhall Specific Plan, and the Compass Blueprint Concept Plan. As such, implementation of Project Alternative 1 would create a less than significant impact with regards to land use and planning. Similar to the Proposed Project, Alternative 1 would require an oak tree permit for the loss of two oak trees that are located within the proposed grading limits and right-of-way alignment and a Hillside Review Permit for the grading of an existing hillside. Approval of the Oak Tree Permit and Hillside Review Permit would reduce land use impacts to less than significant levels. Noise Construction Similar to the Proposed Project, construction of the Alternative 1 Project would require the use of heavy equipment for ground clearing, site grading, and roadway construction. Several pieces of construction equipment operating simultaneously would generate a noise level of approximately 94.6 dBA. The estimated construction noise levels impacting sensitive receptors are expected to exceed the City's daytime noise standards for residential uses (see Table 4.8-8). The construction noise levels would therefore constitute a significant impact. Operational Similar to the Proposed Project, the Alternative 1 Project is anticipated to alter roadway traffic volumes as the Alternative 1 Project would create a new roadway segment connecting Lyons Avenue to Dockweiler Drive. Locations in the vicinity of the Project Site could experience slight changes in noise levels as a result of the change in traffic patterns. The changes in future noise levels along the study -area roadway segments in the project vicinity are for the Proposed Project's near term (Year 2019) impacts would increase local noise levels by a maximum of 2.7 dBA CNEL (at the location of Dockweiler Drive Lyons Avenue/Dockweiler Drive Extension Project 6.3 Alternative 1 SCH No. 2013082016 Page 6.3-12 City of Santa Clarita August 2017 (between Sierra Highway and Valle del Oro). This increase would be inaudible/imperceptible to most people and would not exceed the identified thresholds of significance. At all other roadway segments, the resulting noise levels are anticipated to decrease. As such the Alternative 1 Project's potential to generate a substantial permanent increase in ambient noise levels in the project vicinity above levels existing without the project would be less than significant. The Future (2019) With Project noise levels on the new roadway segment from Lyons Avenue to Valle del Oro are expected to be 63.3 dBA (CNEL) within 50 feet of the centerline of the roadway. The resulting noise levels at the three identified sensitive receptors would be below 52.9 dBA. Thus, the anticipated with project noise levels at all off -site receptor locations would be within the "normally acceptable" range of noise for residential areas. Therefore, the Alternative 1 Project's noise impacts would be less than significant. Transportation and Traffic Alternative 1 to the Proposed Project utilizes the City of Santa Clarita's General Plan proposed alignment for Dockweiler Drive, which identifies the connection of Dockweiler Drive to extend to Arch Street. The Alternative 1 Project would extend Lyons Avenue from its existing terminus at Railroad Avenue, eastward to Dockweiler Drive to provide a T-intersection. Included in the Alternative 1 is re -profiling the intersection of Lyons Avenue and Railroad Avenue to allow the construction of a new SCRA/UP railroad grade crossing east of Railroad Avenue. Alternative 1 is illustrated in Figure 6.3-1. Alternative 1 differs from the Proposed Project by retaining the existing railroad crossing at 13th Street instead of removing it. The following section addresses Alternative 1 Project's impact on transportation and traffic based on the Traffic Study titled, Traffic Impact Analysis: Dockweiler Drive Alignment Project, Santa Clarita, CA, prepared by David Evans and Associates, dated August 8, 2017. The complete Traffic Study is included in Appendix H to this Draft EIR. Opening Year (2019) Conditions With Alternative I Project The Santa Clarita Valley Consolidated Traffic Model (SCVCTM) for Interim Year provided traffic volumes for the Project Year 2019 with the Alternative 1 Project Condition. The model plots outlined the distribution of future traffic with the construction of the Alternative 1 Project. The Project Year 2019 Alternative 1 study intersections are provided in Figure 6.3-3, and the volumes provided in Figure 6.3-4. The analysis for the intersection of Arch Street/Dockweiler Drive and 12th Street/Placerita Canyon Road was conducted as a 5-leg all way stop controlled intersection. The analysis for the intersection of Lyons Avenue and Dockweiler Drive was conducted as a signalized intersection. Unlike the Proposed Project, the intersection of Railroad Avenue and 13th Street would continue to operate. The intersections were analyzed using the capacity analysis methodology. The analysis was conducted with the Project Year 2019 with Alternative 1 Project existing and mitigated study intersection geometries illustrated in Figure 6.3-5. The LOS for the study intersections presented in Table 6.3-1 represents the LOS for the critical movement. This is typically the stop controlled left turn from the minor street. Lyons Avenue/Dockweiler Drive Extension Project 6.3 Alternative 1 SCH No. 2013082016 Page 6.3-13 City of Santa Clarita August 2017 As presented in Table 6.3-1 under Year 2019 with Alternative 1 Condition, most of the study intersections are anticipated to continue to operate at LOS E or better. Like the Proposed Project, the same four intersections are anticipated to operate at LOS F. they are. Sierra Highway and SR-14 Southbound Ramps. Sierra Highway and Placenta Canyon Road. SR-14 Northbound Ramps and Placenta Canyon Road, SR-14 Southbound Ramps and Newhall Avenue. The same mitigation measures presented for the Proposed Project would generally be necessary to accommodate the anticipated Year 2019 traffic and reduce potential impacts for the Alternative I Project.

With mitigation, the SR-14 Northbound Ramps and Placerita Canyon Road intersection (Study Intersection 3) level of service will remain the same at LOS B during the AM peak hour and would increase from LOS F to LOS B during the PM peak hour. With mitigation, the SR-14 Southbound Ramps and Newhall Avenue intersection (Study Intersection 5) levels of service will increase to LOS A from LOS F during both AM and PM peak hours. With the implementation of the mitigation measures summarized in Section 4.9, Traffic and Traffic, Alternative 1 Project's impacts during the 2019 build -out year would also be less than significant. However, Alternativel would not require implementation of mitigation measures 4.9-5 and 4.9-10, as compared to the Proposed Project. Therefore, the Proposed Project and the Alternative 1 Project would both result in a less than significant impact after mitigation. Future (2035) Conditions With Alternative I Project The Santa Clarita Valley Consolidated Traffic Model (SCVCTM) for Build -Out Year provided traffic volumes for the Future Year 2035 with Alternative 1 Condition. The model plots outlined the distribution of future traffic with the construction of the Alternative 1 Project. The analysis of Alternative 1 utilizes the traffic volume projections for the City of Santa Clarita's traffic model together with the existing traffic flow data. The traffic projections are based on the General Plan Buildout. Like the Proposed Project, the buildout includes construction of future roadways Dockweiler Drive between Railroad Avenue and Valle Del Oro, Magic Mountain Parkway from Railroad Avenue to Via Princessa, Via Princessa between Claibourne Lane and Sheldon Avenue, and Santa Clarita Parkway. This also includes the proposed conceptual development of the North Newhall area (809 dwelling unit plus an approximate 11-acre commercial land use). The Future Year 2035 Alternative 1 study intersections are provided in Figure 6.3-6 and the volumes are provided in Figure 6.3-7. The intersections were analyzed using the capacity analysis methodology. The analysis was conducted with the Future Year 2035 Alternative 1 Project Condition existing and mitigated study intersection geometries illustrated in Figure 6.3-8. The LOS for the study intersections presented in Table 6.3-2 represents the LOS for the critical movement. This is typically the stop controlled left turn from the minor street. As presented in Table 6.3-2 under Future Year 2035 with Alternative 1 Project Condition, several of the study intersections are anticipated to operate at LOS F. There are four intersections that are anticipated to operate at LOS F, they are: Sierra Highway and Placerita Canyon Road, Sierra Highway and Newhall Avenue, Valle Del Oro and Dockweiler Drive, and Main Street and Newhall Avenue. Similar to the Proposed Project, mitigation measures are necessary to accommodate the anticipated Future Year 2035 traffic and reduce potential Alternative 1 Project impacts. Lyons Avenue/Dockweiler Drive Extension Project 6.3 Alternative 1 SCH No. 2013082016 Page 6.3-18 City of Santa Clarita August 2017 With mitigation, the Sierra Highway and Placerita Canyon Road intersection (Study Intersection 2) levels of service will increase to LOS D during both AM and PM peak hours. With mitigation, the Sierra Highway and Newhall Avenue intersection (Study Intersection 6) levels of service will increase from LOS E to LOS D during the AM peak hour and LOS F to LOS D during the PM peak hour.

Clarita August 2017 Railroad Crossing Analysis Similar to the Proposers Project, a comparison of the No Build scenario, the Proposed Project scenario, and the Alternative 1 Project scenario for Daily. AM and PM Peak hour traffic vohunes were compiled for the Year 2019 and 2035 conditions as presented in Table 6.3-3 and Table 6.3-4, respectively. Existing conditions remain the same as reported in Section 4.9, Transportation and Traffic. As presented in Table 6.3-3 under Alternative 1 Year 2019, the total average daily railroad crossings is anticipated to be higher under the No Build Condition as compared to the Proposed Project and Alternative 1. Alternative 1 total average daily railroad crossings would result in 3,230 fewer crossings than the No Build condition but would result in 2,340 more railroad crossings than the Proposed Project condition. As presented in Table 6.3-4 under Alternative 1 Year 2035, the total average daily traffic is anticipated to be highest for the Alternative 1 condition as compared to the Proposed Project and No Build Scenario. Alternative 1 total average daily railroad crossings would result in 5,370 more crossings than the No Build condition and 2,510 more railroad crossings as compared to the Proposed Project condition. Accordingly, Alternative 1 would not be preferable over the Proposed Project with respect to minimizing railroad crossings. Bi(yele and Pedestrian Facilities Similar to the Proposed Project, the Alternative 1 would comply with Santa Clarita's circulation goals and enhancing the circulation system by providing bicycle lanes and accessibility to bicycle paths that are fundamental for a comprehensive transportation network.

PROJECT ALTERNATIVES 4. ALTERNATIVE 2 (PROPOSED ALIGNMENT TO ARCH STREET WITHOUT LYONS AT GRADE CROSSING) Similar to the Proposed Project, the Alternative 2 Project would involve the development of the proposed roadway alignment and associated infrastructure for Dockweiler Drive, which would extend Dockweiler Drive to Arch Street. The route would continue along Arch Street to 13'b Street to link the Railroad Avenue. Unlike the Proposed Project, Alternative 2 does not include the roadway segment between the Dockweiler extension and Lyons Avenue, which spans a portion of the Newhall Creek. Additionally, Alternative 2 proposes to maintain and improve the 13th Street rail crossing. The proposed alignment of Dockweiler Drive under Alternative 2 is illustrated in Figure 6.4-1. The proposed street improvements at 13'b Street are depicted in Figure 6.4-2, Alternative 2 13'b Street Improvements. As shown in Figure 6.4-2, the existing westbound travel lanes on 13'b Street approaching Railroad Avenue would be improved with two westbound lanes and a median, with one dedicated left turn lane, one shared through lane and left turn lane, and one dedicated right turn lane. The eastbound traffic lanes on 13'b Street would be improved to provide two through travel lanes. The existing median nose on Railroad Avenue would be removed to reconfigure the four southbound lanes to provide two protected left turn lanes, one dedicated through lane and one shared right turn lane and through lane. The northbound lanes on Railroad Avenue would provide two through lanes, one protected left turn lane and one protected right turn lane. Similar to the Proposed Project, the intersection of Arch Street, 12th Street, Placerita Canyon and Dockweiler Drive would be improved with one of three intersection design configurations. For an illustration of the proposed design configurations for Alternative 2, see Figure 6.4-3, Alternative 2 Option A - 5-Legged Intersection, Figure 6.4-4 — Alternative 2 Option B — Traffic Circle, and Figure 6.4-5 Alternative 2 Option C - 3-Legged Intersection, respectively. The Alternative 2 Project would require improvements to Arch Street and 13th Street to accommodate traffic from the extension of Dockweiler Drive to Arch Street. Roadway improvements would require increasing the width of Arch Street and 13th Street, which would affect several surrounding properties. Figure 6.4-6 depicts the properties that would be impacted at 13th Street at Arch Street under the Alternative 2 Project. The portion of the Project Site to the east of the intersection of Railroad Avenue and 13th Street is bounded by one-story commercial buildings to the west, across Railroad Avenue (See Figure 4.1-3, View 9), industrial and commercial uses to the east (See Figure 2-4, Views 9 and 12), undeveloped land to the north (See Figure 4.1-2, View 5), and Newhall Creek to the south. Photographs of existing surrounding land uses at Railroad Avenue and Lyons Avenue are depicted in Figures 2-3 through 2-4 of the Project Description.

Properties to the south of this portion of the Project Site are zoned SP with a General Plan land use designation of Specific Plan. Properties to the east of this portion of the Project Site are zoned UR1, UR3 and PI, with a General Plan land use designation of Urban Residential One, Urban Residential Three and Public Institutional, respectively. Properties to the west, across Railroad Avenue are zoned SP with a General Plan land use designation of Specific Plan. (See Figure 2-4, Zoning and Land Use Map of Project Site and Surrounding Area). ENVIRONMENTAL ANALYSIS Aesthetics Temporary Construction Impacts The Alternative 2 Project would similarly impact existing views and aesthetic character of the area by grading, stockpiles or debris and soil, building materials and construction equipment, all of which could occupy the field of view of passing motorists, pedestrians and nearby residents. The construction site would continue to be visible from the residential properties on Aden Avenue and from passing motorists on Lyons Avenue, Railroad Avenue, Market and Race Streets, and at the Arch Street/12th Street/Placerita Canyon intersection with the development of the Alternative 2 Project. Thus, the existing visual character of the Project Site would be adversely impacted throughout the duration of the construction period. Therefore, impacts related to aesthetic character of the area during construction would be the same as compared to the Proposed Project, where impacts would be considered significant but temporary. Implementation of Mitigation Measure 4.1-1 would also be recommended for the Alternative 2 Project. Long Term Operational Impacts Upon completion of the Alternative 2 Project the aesthetic character of the Project Site and its immediate surroundings would be permanently altered, but to a lesser extent than the Proposed Project. Views of the hillside on the southeast portion of the Project Site would be similarly altered by grading for the proposed roadway extension. Views of the Project Site at the intersection of Railroad Avenue and 13th Street would be similar to existing views of the intersection, since the Alternative 2 Project includes the improvement of the at -grade railroad crossing. A visual simulation of the views at the Arch Street/12th Street/Placerita Canyon/Dockweiler Drive Intersection is depicted in Figure 4.1-6 in Section 4.1, Aesthetics. The resulting aesthetic impacts under the Alternative 2 Project would be similar to the proposed project and would be as shown in Figure 4.1-6. As the proposed infrastructure improvements would be made in accordance with the City's roadway standards and would be attractively landscaped, aesthetic impacts would be less than significant. Additionally, as noted in Section 2.0, Project Description, the loss of the oak tree at this location (See Figure 4.1-6, Before View, Looking South) would require an oak tree permit and would require replacement tree to be planted as part of the permit approval process, aesthetic impacts associated with the loss of oak trees would be reduced to less than significant levels. Lyons Avenue/Dockweiler Drive Extension Project 6.4 Alternative 2 SCH No. 2013082016 Page 6.4-8 City of Santa Clarita August 2017 As the Alternative 2 Project does not include the roadway extension between Dockweiler Drive and Lyons Avenue, views of this intersection would largely remain unchanged, as compared to the Proposed Project. Like the Proposed Project, the roadway extension would be developed in accordance with the City's roadway standards and design guidelines to ensure the graded hillsides, medians, and walkways are landscaped in a manner that maintains the visual aesthetic quality and character of the City's roadway infrastructure. Therefore, impacts related to long-term operation would be the same as compared to the less than significant impact anticipated for the Proposed Project. Alteration of A Significant Ridgeline Similar to the Proposed Project, construction of the proposed roadway alignment between Dockweiler Drive and Arch Street would permanently alter a significant ridgeline as designated in the City of Santa Clarita General Plan. However, as noted in Section 4.1, Aesthetics, the eastern segment of the Dockweiler alignment was previously approved under a separate project entitlement for The Master's University in 2009, which included a Ridgeline Alteration Permit for the eastern segment of this ridgeline.' As part of the approved entitlements for The Master's University Master Plan in 2009, the irreversible grading and re -contouring of the ridgeline was approved to the western limit of the Master's University Campus. As shown in Figure 4.1-1, the grading limits of the Proposed Project (which would be the same under this Alternative) would retain the gradual elevation profile of the base of the ridgeline leading to the Master's University Campus. Limited views of the altered portion of the ridgeline within the Proposed Project limits would be partially visible from the public rights -of -way along Market Street and Race Street to the south of the Project Site (see Figure 4.1-5 in Section 4.1, Aesthetics). As a project design feature under this Alternative the grading plan would incorporate landform grading practices to blend the manufactured slopes and required drainage benches into the natural topography to the maximum extent feasible. Plant materials will be utilized to protect slopes from slippage and soil erosion and minimize the visual effects of grading and construction on a hillside area. With approval of a Hillside Review Permit, aesthetic impacts associated with the grading of Alternative 2 would be reduced to less than significant levels. Visual Character Similar to the Proposed Project, the Alternative 2 Project would not introduce buildings or development that would block existing views or substantially degrade the visual character of the existing site. The Alternative 2 Project also includes pedestrian, equestrian, and bicycle improvements to Dockweiler Drive that would include wide sidewalks, Class II bike lanes on each side, and a multi -purpose trail on the east side. Class II bike routes will provide a striped lane for one-way bike travel and will be marked with signs and pavement striping. Multi -purpose trails are to be unpaved and will be available for equestrian, hiking, and mountain bike use. These project features would increase accessibility to scenic natural resources including the Newhall Creek and surrounding ridgelines and mountains. Therefore, impacts related to visual character would be the less than significant. I Ibid. Lyons Avenue/Dockweiler Drive Extension Project 6.4 Alternative 2 SCH No. 2013082016 Page 6.4-9 City of Santa Clarita August 2017 Roadway Light and Glare Ambient nighttime lighting for the Alternative 2 Project would be similar to that of the Proposed Project. The Alternative 2 Project would introduce nighttime lighting to the Project Area, which will include pole - mounted streetlights at intersections and lighted bollards along Dockweiler Drive, and would contribute to additional light and glare from the headlights of vehicles utilizing the roadway. Compared to the Proposed Project, Alternative 2 would introduce less lighting and glare sources, as Alternative 2 does not include the roadway connection between Dockweiler Drive and Lyons Avenue. Lighting uses associated with the Alternative 2 Project are not anticipated to substantially impact any surrounding sensitive uses as the streetlights would be installed with downward directional fixtures and would not create light trespass onto any adjacent properties. Light emanating from the Alternative 2 Project would be a relatively low-level indirect source of light illuminating the roadway and pedestrian walkways and would not adversely impact other properties in the immediate area. Additionally, the steep terrain and orientation of the southeastern portion of the Project Site would shield vehicle headlights, signage lighting and streetlights from impacting the residential properties within the Placerita Canyon community to the east and along Market and Race Streets to the west. Overall, the Alternative 2 Project would be expected to slightly increase ambient lighting in the area, but compliance with the design standards and requirements established in the Santa Clarita Municipal Code Section 17.51.050 would mitigate lighting impacts to a less than significant level. Therefore, impacts related to roadway light and glare would be less than significant. Air Quality Construction Construction of the Alternative 2 Project would occur over an approximately 12-month timeframe and would involve clearing, grading, excavation, trenching, and asphalt paving. Sources of emissions during construction include: stationary and mobile uses of construction equipment, construction vehicles (heavy- duty construction vehicles and worker vehicles), and energy use. Additionally, earthwork and construction activities would generate fugitive dust emissions. These construction -related emissions and their associated air quality impacts would be short-term in nature and limited only to the period when construction activity is actively taking place. The Alternative 2 Project's construction emissions would similar to the emissions generated under the Proposed Project, but slightly reduced as this alternative would involve less mass grading. The increased emissions associated with the Arch Street to 13th Street improvements would be offset by the avoidance of grading associated with the Dockweiler to Lyons connection. As the Proposed Project emissions would be below SCAQMD's significance thresholds for all criteria pollutants, the Alternative 2 regional construction air quality emissions would be less than significant. AQMP Consistency The Alternative 2 Project would not exceed the AQMD's significance thresholds for regional construction emissions and thus would not increase the frequency or severity of existing air quality violations or cause or contribute to new air quality violations within the Basin. The Alternative 2 Project is consistent with Lyons Avenue/Dockweiler Drive Extension Project 6.4 Alternative 2 SCH No. 2013082016 Page 6.4-10 City of Santa Clarita August 2017 the AQMP and would not interfere with attainment of air quality levels identified in the AQMP. Similar to the Proposed Project, the Alternative 2 Project would help reduce congestion and vehicles per miles travelled by providing sidewalks and bicycle lanes and by providing direct access from the residential area and Master's University area to the Jan Heidt Newhall Metrolink Station and Old Town Newhall. The Alternative 2 Project encourages alternative modes of transportation other than motor vehicles and would be consistent with the goals and objectives of the AQMP to reduce vehicle emissions throughout the Basin. Localized Construction Emissions Similar to the Proposed Project, the Alternative 2 Project would result in significant localized air emissions in close proximity to residential land uses within 100 meters of the Project Site on a temporary and intermittent basis during construction. Localized NOx and CO emissions would be below the significance thresholds at all sensitive receptor locations. However, localized thresholds would be exceeded for PMIO and PM25 emissions at two locations: (1) the single family residential land uses located immediately north of the Project Site (within a proximity of 100 meters) and (2) the residential land uses within 100 meters south of the Project Site in the vicinity of Market Street and Race Street. Localized emissions would be below the stated thresholds for any land use located further than 100 meters from the Project Site. Therefore, notwithstanding implementation of mitigation measures 4.2-1 through 4.2-4, localized air quality impacts resulting from construction activities would be considered significant and unavoidable. Operational Emissions Although the Alternative 2 Project would not directly generate any new vehicle trips, it would result in changes to the traffic circulation in the vicinity and would alter the average daily traffic volumes and peak hour traffic volumes at local intersections. A CO hotspot analysis was conducted for the Proposed Project, and as the Alternative 2 Project is within the same envelope as the Proposed Project, it was found that, under worst -case conditions, future CO concentrations at each intersection would not exceed the state 1- hour and 8-hour standards with or without the development of the Proposed Project. Therefore, no significant project -related impact would occur relative to future carbon monoxide concentrations of the Alternative 2 Project. The Alternative 2 Project would have a less than significant impact with respect to this criterion. Biological Resources Habitat Modification Vegetation The Alternative 2 Project Site grading plans for the roadway extension of Dockweiler Drive to the to Arch Street would be similar to the Proposed Project; however, the Alternative 2 Project would not include the roadway extension of Lyons Avenue to Dockweiler Drive. As such, the Alternative 2 Project would be within the envelope of the Project Site analyzed for the Proposed Project; however, less acres of Lyons Avenue/Dockweiler Drive Extension Project 6.4 Alternative 2 SCH No. 2013082016 Page 6.4-11 City of Santa Clarita August 2017 vegetation would be removed as compared to the Proposed Project. Of the vegetation communities impacted by the Alternative 2 Project, Disturbed California Sagebrush -California Buckwheat Scrub would be the dominant plant community present by area and approximately less than 0.63 acre of this habitat would be lost through site grading and project implementation. The loss of less than 2 acres of vegetation is considered adverse; although, due to the Site's disturbance history, its small size, the lack of sensitive plant communities, the lack of structure for wildlife, and high percentage of invasive and non- native plant species generally associated with disturbed areas, impacts associated with the loss of less than 2 acres of vegetation present on -site is considered less than significant. The only special -status plants observed during the field investigation were two coast live oaks. No other special -status plants are considered to have a high potential for occurrence within the Project Site. A permit is required for the encroachment into the Protected Zone. Wildlife Similar to the Proposed Project, construction activity and grading operations of the Project Site for the Alternative 2 Project would disturb and/or threaten the survival of common wildlife species present on - site. It is expected that species of low mobility, particularly small mammals, amphibians, and reptiles, would be lost during site preparation, grading, and construction. Site grading and project implementation would eliminate approximately less than approximately 2 acres of natural habitat present on -site, and would result in an incremental reduction in native wildlife species abundance and diversity. However, due to nearby urban development and the associated human disturbance, field investigations indicate wildlife diversity and abundance on the Project Site is relatively low. Most the species of mammals, birds, and reptiles observed on -site or thought to occur on -site are relatively common. Project implementation is not expected to cause current wildlife population of common species on or adjacent to the Project Site to drop below self-sustaining levels. Therefore, impacts to common wildlife species are not considered significant. Project -related activities associated with site preparation and construction could result in the direct loss of individuals of one special -status wildlife species (the silvery legless lizard) and of active nests or the abandonment of active nests by adult birds should grading occur during nesting season. The loss of a California species of special concern and active bird nests would be a considered significant without mitigation. Implementation of mitigation measures 4.3-2 and 4.3-3 would reduce impacts to the silvery legless lizard and nesting birds to a less than significant level. Federally Protected Wetlands Based on field investigations, two CDFW jurisdictional features occur within the Project Site for the Proposed Project, the Newhall Creek and a small ephemeral drainage that is a tributary to Newhall Creek. There is also a small area of narrow -leaf willow thicket, which probably does not qualify as a Federally jurisdictional wetland. As the Alternative 2 Project does not include the extension of Lyons Avenue to Dockweiler Drive, the Alternative 2 Project would not result in either temporary or permanent impacts to the areas of the Newhall Creek and its associated tributary and are classified as "riverine and related Lyons Avenue/Dockweiler Drive Extension Project 6.4 Alternative 2 SCH No. 2013082016 Page 6.4-12 City of Santa Clarita August 2017 permanent water, with continuous flow at least seasonally." As such no impacts to jurisdictional resources would occur. Wildlife Movement and Corridors Similar to the Proposed Project, the Project Site for Alternative 2 is generally surrounded on three sides by development and road networks. Although the Newhall Creek is located to the west of the Project Site for the Alternative 2 Project, the Project would not would not result in any barrier to wildlife movement and would not impede the ability of Newhall Creek to function as a wildlife movement corridor. The Alternative 2 Project as proposed would not result in significant impacts to wildlife movement. Construction Activity Similar to the Proposed Project, construction -related activities, particularly site clearing, grading, and the implementation of the road surface, could have adverse effects on plant and wildlife habitat, and together, would be considered a significant impact. Implementation of Mitigation Measure 4.3-4 would reduce these construction -related impacts to a less than significant level. Operation Increase in Populations of Non -Native Species Similar to the Proposed Project, non-native plants and wildlife are expected to increase on -site, because these species are more adapt to urban environments and can out -compete native species. Historical and ongoing development in the vicinity of the Project Site has already supported continual and ongoing increase and proliferation of non-native plant and wildlife species in the vicinity of the Project Site. Development of the Alternative 2 Project is not expected to substantially increase the distribution of non- native plants and wildlife. With compliance to Mitigation Measure 4.3-5, Alternative 2 Project impacts would be less than significant. Increased Light and Glare Similar to the Proposed Project, it is anticipated that nighttime lighting would increase in areas adjacent to the Project Site, which can disturb breeding and foraging behavior, movement, and can potentially alter breeding cycles of birds, mammals, and nocturnal invertebrates. Because of surrounding development around the Project Site, nearby natural areas already receive some nighttime lighting. The Alterantive 2 Project would increase light and glare effects near to the Newhall Creek corridor. Implementation of Mitigation Measure 4.3-6 would decrease this impact to a less than significant level. Stormwater and Urban Runoff Similar to the Proposed Project, it is expected that stormwater runoff would be limited to pavement runoff during periodic storm events. It is reasonable to assume runoff could substantially affect special -status species potentially occurring downstream from the Project Site (i.e. Newhall Creek), incrementally diminish habitat, and degrade the quality of the environment. With the compliance to City's standard Lyons Avenue/Dockweiler Drive Extension Project 6.4 Alternative 2 SCH No. 2013082016 Page 6.4-13 City of Santa Clarita August 2017 stormwater requirements and required design criteria, impacts to Newhall Creek resulting from Stormwater runoff would be less than significant. Cultural Resources Cultural and Historic Resources No cultural or historic habitable structures are located on -site, and as such, similar to the Proposed Project the Alternative 2 Project would not have the potential to adversely impact any historic or cultural resources. Archaeological Resources No known archeological sites are identified within the Project Site for the Alternative 2 Project. While, portions of the Project Site are improved with roadways, the Alternative 2 Project will consist of earthwork activities, such as grading and excavation, in areas that are currently undeveloped. Construction -related earthwork activities may result in the accidental discovery of prehistoric or historic archaeological resources or Native American burial sites. Implementation of mitigation measures 4.4-1 will reduce impacts to a less than significant level. Paleontological Resources The Alternative 2 Project is within the envelope of the Project Site for the Proposed Project. The records search conducted by the Vertebrate Paleontology Department of the Natural History Museum of Los Angeles County yielded no known fossil localities within the Project Site for the Proposed Project. The closest vertebrate fossil localities are from the Saugus Formation, located directly north of the Project Site. While it is possible that fossilized materials may be discovered during site preparation and construction, specifically grading and excavation activities, precautionary measures set forth in mitigation measure 4.4-2 would reduce any potential adverse impacts to paleontological resources to a less than significant level. Tribal Cultural Resources Similar to the Proposed Project, Alternative 2 would not have a direct impact upon known tribal cultural resources. Nevertheless, provisions for the identification and evaluation of accidentally discovered archeological resources would be implemented in accordance with mitigation measure 4.4-1. With the incorporation of mitigation measure 4.4-1, impacts upon tribal resources would be less than significant. Geology And Soils The Project Site is underlain by Saugus Formation, Pacoima Formation, Quaternary alluvium and artificial fill and has historic high groundwater elevations greater than 50 feet in depth. The Project Site is located in the State of California Seismic Hazard Zone map for the Newhall Quadrangle. Hazards related to seismic -related ground failures (including ground rupture and liquefaction) are considered low. Lyons Avenue/Dockweiler Drive Extension Project 6.4 Alternative 2 SCH No. 2013082016 Page 6.4-14 City of Santa Clarita August 2017 All slopes should be evaluated by the Project Geotechnical engineer at the planning and design stages. The hillside area of the site is designated on the State of California Seismic Hazard Zone Map to have earthquake -induced slope instability. No landslides have been mapped on the Project Site. Remedial measures will be required where ascending or descending cut slopes are not stable as determined by geologic or geotechnical stability analyses. The potential for earthquake -induced slope failures is considered low provided that future geologic and geotechnical evaluations and recommendations for slope stability is incorporated into design and construction. Additionally, specific recommendations for design and construction should be provided to address soil stability, including: hydro -compression, expansive soils, rippability, the handling of oversized material, soil corrosivity, shirking and bulking of materials, and the handling of the need for retaining wall. No oil wells have been drilled on or immediately adjacent to the Project Site. If any undocumented oil wells are encountered during future construction operations at the site, their location(s) should be surveyed and the current well conditions evaluated. Water wells have been drilled in the vicinity of the proposed road alignments. If one of these water well is within the proposed road alignment, or if a water well is encountered during future construction operations at the site, the location should be surveyed and the potential impacts to well conditions should be evaluated. The implementation of mitigation measure 4.5-1 would insure that potential Alternative 2 Project impacts would be reduced to a less than significant level. Hydrology And Water Quality Construction During the construction phase, the typical pollutants that affect surface water quality are: sediment from soil erosion, petroleum products (gasoline, diesel, kerosene, oil and grease), hydrocarbons from asphalt paving, construction equipment leaks, paints and solvents, detergents, fertilizers, and pesticides. Similar to the Proposed Project, the Alternative 2 Project would be required to prepare and implement a SWPPP prior to earthwork activities that will put best management practices and erosion control measures to prevent pollution in stormwater discharge. All project construction activities would comply with the City's grading permit regulations, which require the implementation of grading and dust control measures, including a wet weather erosion control plan if construction occurs during rainy season, as well as inspections to ensure that sedimentation and erosion is minimized. Therefore, through compliance with NPDES requirements and City grading regulations, the Alternative 2 Project's construction impacts related to water quality would not violate any water quality standards or waste discharge requirements or otherwise substantially degrade water quality. Construction -related impacts to hydrology and water quality would therefore be less than significant. Lyons Avenue/Dockweiler Drive Extension Project 6.4 Alternative 2 SCH No. 2013082016 Page 6.4-15 City of Santa Clarita August 2017 Operation Once the Alternative 2 Project has been constructed, urban runoff could include the aforementioned contaminants, trace metals, landscape maintenance debris, dry product spills, and "nuisance flows" from landscape irrigation during the dry -season. In accordance with NPDES requirements, the Project Applicant would be required to have a Project -specific SUSMP in place during the operational life of the Project to address the management of runoff from the proposed roadway extension. The SUSMP would include site design, source control, low -impact development, and best management practices. Therefore, implementation of the storm water quality plan would reduce water quality impacts during the Alternative 2 Project's operation to less than significant. Inundation and Flooding Unlike the Proposed Project, the Alternative 2 Project does include the roadway extension from Lyons Avenue to Dockweiler Drive, which spans a portion of the Newhall Creek. As such, the Alternative 2 Project would not include the development of a new bridge across Newhall Creek or require embankment protection to the roadway and creek and this alternative would not have any impacts upon hydrologic flows within Newhall Creek. Land Use And Planning Implementation of the Alternative 2 Project would not disrupt or physically divide an established community. Monument signage will properly guide traffic and identify the entrance to the Placerita Canyon community as a residential community with no through access. Additionally, similar to the Proposed Project, the Alternative 2 Project will provide increased pedestrian and vehicular access in the area. The Alternative 2 Project would not conflict with any applicable land use plans, policies, or regulations, including: the Regional Transportation Plan / Sustainable Communities Strategy, City of Santa Clarita Municipal Code, City of Santa Clarita General Plan (including the Circulation Element), the Placerita Canyon Special Standards District and North Newhall Area, Old Town Newhall Specific Plan, and the Compass Blueprint Concept Plan. As such, implementation of Project Alternative 2 would create a less than significant impact with regards to land use and planning. Similar to the Proposed Project, Alternative 2 would require an oak tree permit for the loss of two oak trees that are located within the proposed grading limits and right-of-way alignment and a Hillside Review Permit for the grading of an existing hillside. Approval of the Oak Tree Permit and Hillside Review Permit would reduce land use impacts to less than significant levels. Lyons Avenue/Dockweiler Drive Extension Project 6.4 Alternative 2 SCH No. 2013082016 Page 6.4-16 City of Santa Clarita August 2017 Noise Construction Similar to the Proposed Project, construction of the Alternative 2 Project would require the use of heavy equipment for ground clearing, site grading, and roadway construction. Several pieces of construction equipment operating simultaneously would generate a noise level of approximately 94.6 dBA. The estimated construction noise levels impacting sensitive receptors are expected to exceed the City's daytime noise standards for residential uses (see Table 4.8-8). The construction noise levels would therefore constitute a significant impact. Operational Similar to the Proposed Project, the Alternative 2 Project is anticipated to alter roadway traffic volumes as the Proposed Project would create a new roadway segment connecting Lyons Avenue to Dockweiler Drive. Locations in the vicinity of the Project Site could experience slight changes in noise levels as a result of the change in traffic patterns. The changes in future noise levels along the study -area roadway segments in the project vicinity are for the Proposed Project's near term (Year 2019) impacts would increase local noise levels by a maximum of 2.7 dBA CNEL (at the location of Dockweiler Drive (between Sierra Highway and Valle del Oro). This increase would be below the identified thresholds of significance. At all other roadway segments, the resulting noise levels are anticipated to decrease. As such the Alternative 2 Project's potential to generate a substantial permanent increase in ambient noise levels in the project vicinity above levels existing without the project would be less than significant. The Future (2019) With Project noise levels on the new roadway segment from Lyons Avenue to Valle del Oro are expected to be 63.3 dBA (CNEL) within 50 feet of the centerline of the roadway. The resulting noise levels at the three identified sensitive receptors would be below 52.9 dBA. Thus, the anticipated with project noise levels at all off -site receptor locations would be within the "normally acceptable" range of noise for residential areas. Therefore, the Alternative 2 Project's noise impacts would be less than significant. The Alternative 2 Project would direct more traffic through Arch Street and 13th Street in lieu of the Dockweiler/Lyons Extension, which would not be constructed as part of this alternative. The land uses along Arch Street and 13th Street are commercial properties and are not considered sensitive land uses for purposes of evaluating noise impacts. Thus noise impacts associated with the change of traffic flows under this alternative would be less than significant. Transportation and Traffic Alternative 2 to the Proposed Project utilizes the City of Santa Clarita's General Plan proposed alignment for Dockweiler Drive, which identifies the connection of Dockweiler Drive to extend to Arch Street. The route will continue along Arch Street to 13th Street to link to Railroad Avenue. Unlike the Proposed Project, Alternative 2 does not include the roadway segment between the Dockweiler extension and Lyons Avenue. Additionally, Alternative 2 proposes to maintain and improve the 13th Street rail crossing. Lyons Avenue/Dockweiler Drive Extension Project 6.4 Alternative 2 SCH No. 2013082016 Page 6.4-17 City of Santa Clarita August 2017 Compared to the Proposed Project, the Alternative 2 Project includes sixteen study intersections and does not contain Intersection 17, which is Lyons Avenue and Dockweiler Drive. Alternative 2 is illustrated in Figure 6.4-1. The following section addresses Alternative 2 Project's impact on transportation and traffic based on the Traffic Study titled, Traffic Impact Analysis: Dockweiler Drive Alignment Project, Santa Clarita, CA, prepared by David Evans and Associates, dated August 8, 2017. The complete Traffic Study is included in Appendix H to this Draft EIR. Opening Year (2019) Conditions With Alternative 2 Project The Santa Clarita Valley Consolidated Traffic Model (SCVCTM) for Interim Year provided traffic volumes for the Project Year 2019 with Alternative 2 Project Condition. The model plots outlined the distribution of future traffic with the construction of the Alternative 2 Project. The Project Year 2019 Alternative 2 study intersections are provided in Figure 6.4-7, and the volumes provided in Figure 6.4-8. The analysis for the intersection of Arch Street/Dockweiler Drive and 12th Street/Placerita Canyon Road was conducted as a 5-leg all way stop controlled intersection. The intersections were analyzed using the capacity analysis methodology. The analysis was conducted with the Project Year 2019 with Alternative 2 Project existing and mitigated study intersection geometries illustrated in Figure 6.4-9. The LOS for the study intersections presented in Table 6.4-1 represents the LOS for the critical movement. This is typically the stop controlled left turn from the minor street. As presented in Table 6.4-1 under Year 2019 with Alternative 2 Condition, most of the study intersections are anticipated to continue to operate at LOS E or better. Four intersections are anticipated to operate at LOS F, they are: Sierra Highway and SR-14 Southbound Ramps, Sierra Highway and Placerita Canyon Road, SR-14 Northbound Ramps and Placerita Canyon Road, SR-14 Southbound Ramps and Newhall Avenue. The same mitigation measures presented for the Proposed Project would generally be necessary to accommodate the anticipated Year 2019 traffic and reduce potential impacts for the Alternative 2 Project.

With mitigation, the Sierra Highway and Placerita Canyon Road intersection (Study Intersection 2) level of service will remain the same at LOS C during the AM peak hour and will increase to LOS D during the PM peak hour. With mitigation, the SR-14 Northbound Ramps and Placerita Canyon Road intersection (Study Intersection 3) level of service will remain the same at LOS B during the AM peak hour and will increase to LOS B during the PM peak hour. With mitigation, the SR-14 Southbound Ramps and Newhall Avenue intersection (Study Intersection 5) levels of service will increase to LOS A during both AM and PM peak hours. With the implementation of the mitigation measures summarized in Section 4.9, Traffic and Circulation, Alternative 2 Project's impacts during the 2019 build -out year would also be less than significant. However, Alternative 2 would not require implementation of mitigation measures 4.92-2. 4.9- 4 and 4.9-5, as compared to the Proposed Project. Therefore, the Proposed Project and the Alternative 2 Project would both result in a less than significant impact after mitigation. Future (2035) Conditions With Alternative 2 Project The Santa Clarita Valley Consolidated Traffic Model (SCVCTM) for Build -Out Year provided traffic volumes for the Future Year 2035 with Alternative 2 Condition. The model plots outlined the distribution of future traffic with the construction of the Alternative 2 Project. The analysis of Alternative 2 utilizes the traffic volume projections for the City of Santa Clarita's traffic model together with the existing traffic flow data. The traffic projections are based on the General Plan Buildout. The buildout includes construction of future roadways Dockweiler Drive between 13lb Street and Valle Del Oro, Magic Mountain Parkway from Railroad Avenue to Via Princessa, Via Princessa between Claibourne Lane and Sheldon Avenue, and Santa Clarita Parkway. This also includes the proposed conceptual development of the North Newhall area (809 dwelling unit plus an approximate 11-acre commercial land use). The Future Year 2035 Alternative 2 study intersections provided in Figure 6.4-10, the volumes provided in Figure 6.4-11. The intersections were analyzed using the capacity analysis methodology. The analysis was conducted with the Future Year 2035 Alternative 2 Project Condition existing and mitigated study intersection geometries illustrated in Figure 6.4-12. The LOS for the study intersections presented in Table 6.4-2 represents the LOS for the critical movement. This is typically the stop controlled left turn from the minor street. As presented in Table 6.4-2 under Future Year 2035 with Alternative 2 Project Condition, several of the study intersections are anticipated to operate at LOS F. There are five intersections that are anticipated to operate at LOS F, they are: Sierra Highway and Placerita Canyon Road, Sierra Highway and Newhall Avenue, Valle Del Oro and Dockweiler Drive, Railroad Avenue and 13th Street, and Main Street and Newhall Avenue. Mitigation measures are necessary to accommodate the anticipated Future Year 2035 traffic and reduce potential Alternative 2 Project impacts. With mitigation, the Sierra Highway and Placerita Canyon Road intersection (Study Intersection 2) levels of service will increase from a LOS F to LOS D during both AM and PM peak hours. With mitigation, the Sierra Highway and Newhall Avenue intersection (Study Intersection 6) levels of service will increase from LOS E to LOS D during the AM peak hour and LOS F to LOS D during the PM peak hour.

Alternative 2's total average daily railroad crossings would result in 6,390 fewer crossings as compared to the No Build condition and 820 fewer railroad crossings as compared to the Proposed Project condition. For the Year 2035 Condition, the total average daily traffic is anticipated to be highest under the Proposed Project Condition. Alternative 2 would result in 3,370 fewer crossings under Alternative 2 as compared to the No Build condition and 6,230 fewer crossings than the Proposed Project condition. As such, Alternative 2 would be preferable over the No Build and Proposed Project scenarios. Bicycle and Pedestrian Facilities Similar to the Proposed Project, the Alternative 2 would comply with Santa Clarita's circulation goals and enhancing the circulation system by providing bicycle lanes and accessibility to bicycle paths that are fundamental for a comprehensive transportation network.

PROJECT ALTERNATIVES 5. ENVIRONMENTALLY SUPERIOR ALTERNATIVE Section 15126.6 of the State CEQA Guidelines requires that an "environmentally superior" alternative be selected among the alternatives that are evaluated in the EIR. In general, the environmentally superior alternative is the alternative that would be expected to generate the fewest adverse impacts. The environmentally superior alternative would be the No Project Alternative. The No Project Alternative would eliminate the Project's significant and unavoidable impacts related to localized construction emissions, and construction noise and vibration impacts. However, the No Project Alternative would not achieve any of the stated Project Objectives, as it would maintain the status quo. As required by CEQA, when the No Project Alternative is shown to be environmentally superior over the Proposed Project, a separate Environmentally Superior Project Alternative shall be identified among the alternatives analyzed within the EIR. Based on a review of the project alternatives identified in this EIR, neither of the alternatives would be effective in eliminating the Project's significant and unavoidable impacts. Table 6.5-1, Environmentally Superior Alternative Matrix presents a summary of the impact conclusions for each alternative relative to the impact statements for each impact areas evaluated in the EIR for the Proposed Project. Of the alternatives evaluated, the Alternative 2 Project would reduce the footprint of the Project Site, as it excludes the Lyons Avenue Extension to Dockweiler Drive, and maintains the at -grade crossing at 13th Street. A comparison of the Alternative 1 Project to the Alternative 2 Project is provided below in Table 6.5-1. As shown in the table below, although both alternatives are very similar with respect to environmental impacts; however, the Alternative 2 Project's reduced Project Site footprint has the potential to reduce impacts more so than the Alternative 1 Project. For that reason, the Alternative 2 Project is identified as the environmentally superior alternative. A discussion of the changes to impacts between the Alternative 1 Project and the Alternative 2 Project are further discussed below. Similar to the Proposed Project, the Alternative 1 Project would involve the development of the proposed roadway alignment and associated infrastructure, which would include a new at -grade crossing and a secondary east -west arterial roadway connecting Lyons Avenue to the proposed Dockweiler Drive extension that would connect Dockweiler Drive to a new five -leg intersection at the Arch Street/12th Street/Placerita Canyon intersection. The Alternative 1 Project differs from the Proposed Project by improving the existing at -grade crossing at the intersection of 13th Street and Railroad Avenue instead of removing the crossing, as proposed by the Proposed Project. Lyons Avenue/Dockweiler Drive Extension Project 6.5 Environmentally Superior Alternative SCH No. 2013082016 Page 6.5-1 City of Santa Clarita August 2017 Table 6.5-1 Euiironinentaliy Superior Alternative Matrix No Project Environmental Impacts Proposed Project Altermative 1 Alternative 2 LTS LTS Aesthetics LTS NI (same) (reduced) SU SU Air Quality SU NI (same) (same) LTS LTS Biological Resources LTS NI (same) (reduced) LTS LTS Cultural Resources LTS NI (sane) (reduced) LTS LTS Geology/Soils LTS NI (sane) (reduced) Hydrology/Water LTS LTS LTS NI Quality (sane) (reduced) LTS LTS Land Use and Planning LTS NI (same) (same) SU SU Noise SU NI (same) (same) Traffic LTS NI LTS LTS (same) (reduced) Notes: LTS = Less Than Significant Impact after mitigation (where mitigation is needed); SU= Significant and Unavoidable Impact: NI = No Impact. All impact conclusions refer to the level of impact after mitigation. Impact comparisons as to the same, increased or reduced refers to the level of impact as compared to the Proposed Project. The Alternative 2 Project would involve the development of the proposed roadway alignment and associated infrastructure for Dockweiler Drive, which would extend Dockweiler Drive to Arch Street. The route would continue along Arch Street to 13a` Street to link the Railroad Avenue. Unlike the Proposed Project. Alternative 2 does not include the roadway segment between the Dockweiler extension and Lyons Avenue, which spans a portion of the Newhall Creek. Additionally. Alternative 2 proposes to maintain and improve the 13'b Street rail crossing. Therefore, as further discussed below, the Alternative 2 Project would result in slightly reduced impacts with respect to aesthetics, biological resources, hydrology and water quality impacts, and traffic and transportation. Aesthetics With respect to aesthetics, both project alternatives would result in less than significant impacts with respect to the loss of a significant ridgeline, as both alternatives would extend south to the extension of Dockweiler Drive to the westerly limits of the approved segment of the Master's University Campus. AS noted in Section 4.1.. Aesthetics, the eastern segment of the Dockweiler alignment was previously approved under a separate project entitlement for The Master's University in 2009, which included a Lyons AvenueDockweiler Drive Extension Project 6.5 Envirannentally Superior Alternative SCH No. 2013082016 Page 6.5-2 City of Santa Clarita August 2017 Ridgeline Alteration Permit for the eastern segment of this ridgeline.' As part of the approved entitlements for The Master's University Master Plan in 2009, the irreversible grading and re -contouring of the ridgeline was approved to the western limit of the Master's University Campus. However, the Alternative 2 Project would not alter existing views of the Lyons Avenue and Railroad Avenue intersection and would therefore have a slightly reduced impact to existing views as compared to the Proposed Project and Alternative 1. Additionally, while Alternative 2 would still require a Hillside Review Permit and an Oak Tree Permit for the loss of one oak tree that is located within the proposed alignment, this Alternative would require the removal of one less oak tree than the Proposed Project and Alternative 1. Air Quality Both the Alternative 1 Project and Alternative 2 Project would result in significant localized air emissions in close proximity to residential land uses within 100 meters of the Project Site on a temporary and intermittent basis during construction. However, notwithstanding implementation of mitigation measures 4.2-1 through 4.2-4, localized air quality impacts resulting from construction activities would be considered significant and unavoidable for all both project alternatives. With respect to operational Air Quality impacts, although neither project alternatives would directly generate new vehicle trips, both alternatives would result in changes to the traffic circulation in the vicinity and would alter the average daily traffic volumes and peak hour traffic volumes at local intersections. However, as discussed in Section 4.2 Air Quality, under worst -case conditions, future CO concentrations at each intersection of the CO hot spot analysis conducted for the Proposed Project would not exceed the state 1-hour and 8-hour standards with or without the development of the Proposed Project. Therefore, no significant project -related impact would occur relative to future carbon monoxide concentrations. As the both alternative projects are within the envelope of the Proposed Project, the alternative projects would have a less than significant impact with respect to operational air quality impacts. Biological Resources As the Alternative 2 Project does not include the extension of Lyons Avenue to Dockweiler Drive, it would not result in either temporary or permanent impacts to the two CDFW jurisdictional features that occur within the Project Site for the Proposed Project and Alternative 1 Project, which includes the Newhall Creek and a small ephemeral drainage that is a tributary to Newhall Creek. As such, the Alternative 2 Project would have no impact with respect to federally protected wetland and implementation of mitigation Measures 4.3-3 would not be applicable to the Alternative 2 Project. Although all three alternatives would result in a less than significant impact with respect to biological resources with implementation of mitigation measures 4.3-1 through 4.3-6, Alternative 2 would result in slightly reduced impacts, as it would not require implementation of mitigation measure 4.3-3. I Ibid. Lyons Avenue/Dockweiler Drive Extension Project 6.5 Environmentally Superior Alternative SCH No. 2013082016 Page 6.5-3 City of Santa Clarita August 2017 Cultural Resources No cultural or historic habitable structures are located on -site, and as such, neither Alternative would have the potential to adversely impact any known historic or cultural resources. Additionally, no known archeological or paleontological sites are identified within the Project Site. While, portions of the Project Site are improved with roadways, both alternatives will consist of earthwork activities, such as grading and excavation, in areas that are currently undeveloped. Construction -related earthwork activities may result in the accidental discovery of prehistoric or historic archaeological or paleontological resources or Native American burial sites. Implementation of mitigation measures 4.4-1 and 4.4-2 would reduce impacts to a less than significant level for both alternatives. However, because Alternative 2 would involve less grading, and would avoid grading within the floodplain, it would have a reduced potential for inadvertent finds associated with archaeological, paleontological and tribal cultural resources. Geology and Soils The Project Site is underlain by Saugus Formation, Pacoima Formation, Quaternary alluvium and artificial fill and has historic high groundwater elevations greater than 50 feet in depth. The Project Site is located in the State of California Seismic Hazard Zone map for the Newhall Quadrangle. Hazards related to seismic -related ground failures (including ground rupture and liquefaction) are considered low. Therefore, with implementation of mitigation measure 4.5-1, both alternatives would result in a less than significant impact with respect to geology and soils. However, because Alternative 2 would involve less grading, and would avoid grading within the floodplain, it would have a reduced potential for soil erosion, loss of topsoil and potential for altering natural landforms. Hydrology and Water Quality Unlike the Proposed Project and Alternative 1 Project, the Alternative 2 Project does not include the roadway extension from Lyons Avenue to Dockweiler Drive, which spans a portion of the Newhall Creek. As such, the Alternative 2 Project would not include the development of a new bridge across Newhall Creek or require embankment protection to the roadway and creek. Although all three project scenarios would result in a less than significant impacts with respect to hydrology and water quality, as all the three projects would be required to comply with the current regulatory and State permitting agencies, under the Alternative 2 Project, impacts related to hydrology and water quality would be reduced as Alternative 2 would avoid grading within the floodplain. As such the potential to alter existing storm flows through Newhall Creek would be avoided. Land Use and Planning Implementation of the both alternative projects would not disrupt or physically divide an established community. Monument signage will properly guide traffic and identify the entrance to the Placerita Canyon community as a residential community with no through access. Additionally, similar to the Proposed Project, both alternative projects will provide increased pedestrian and vehicular access in the area. Both alternatives would not conflict with any applicable land use plans, policies, or regulations, including: the Regional Transportation Plan / Sustainable Communities Strategy, City of Santa Clarita Lyons Avenue/Dockweiler Drive Extension Project 6.5 Environmentally Superior Alternative SCH No. 2013082016 Page 6.5-4 City of Santa Clarita August 2017 Municipal Code, City of Santa Clarita General Plan (including the Circulation Element), the Placerita Canyon Special Standards District and North Newhall Area, Old Town Newhall Specific Plan, and the Compass Blueprint Concept Plan. As such, implementation of either alternative would create a less than significant impact with regards to land use and planning. Noise Construction Similar to the Proposed Project, construction of both alternatives would require the use of heavy equipment for ground clearing, site grading, and roadway construction. Several pieces of construction equipment operating simultaneously would generate a noise level of approximately 94.6 dBA. The estimated construction noise levels impacting sensitive receptors are expected to exceed the City's daytime noise standards for residential uses (see Table 4.8-8). The construction noise levels would therefore constitute a significant impact with respect to both alternative projects. Operational Similar to the Proposed Project, the Alternative 2 Project is anticipated to alter roadway traffic volumes as the Proposed Project would create a new roadway segment connecting Lyons Avenue to Dockweiler Drive. Locations in the vicinity of the Project Site could experience slight changes in noise levels as a result of the change in traffic patterns. The changes in future noise levels along the study -area roadway segments in the project vicinity are for the Proposed Project's near term (Year 2019) impacts would increase local noise levels by a maximum of 2.7 dBA CNEL (at the location of Dockweiler Drive (between Sierra Highway and Valle del Oro). This increase would be below the identified thresholds of significance. At all other roadway segments, the resulting noise levels are anticipated to decrease. As such the Proposed Project's potential to generate a substantial permanent increase in ambient noise levels in the project vicinity above levels existing without the project would be less than significant. The Future (2019) With Project noise levels on the new roadway segment from Lyons Avenue to Valle del Oro are expected to be 63.3 dBA (CNEL) within 50 feet of the centerline of the roadway. The resulting noise levels at the three identified sensitive receptors would be below 52.9 dBA. Thus, the anticipated with project noise levels at all off -site receptor locations would be within the "normally acceptable" range of noise for residential areas. Therefore, the Alternative 2 Project's noise impacts would be less than significant. The Alternative 2 Project would direct more traffic through Arch Street and 13th Street in lieu of the Dockweiler/Lyons Extension, which would not be constructed as part of this alternative. The land uses along Arch Street and 13th Street are commercial properties and are not considered sensitive land uses for purposes of evaluating noise impacts. Thus noise impacts associated with the change of traffic flows under this alternative would be less than significant. Lyons Avenue/Dockweiler Drive Extension Project 6.5 Environmentally Superior Alternative SCH No. 2013082016 Page 6.5-5 City of Santa Clarita August 2017 Transportation and Traffic Opening Year (2019) Conditions As presented in Table 6.3-1 under Year 2019 with Alternative 1 Condition and Table 6.4-1 under Year 2019 with Alternative 2 Condition, most of the study intersections are anticipated to continue to operate at LOS E or better. Like the Proposed Project, the same four intersections are anticipated to operate at LOS F, they are: Sierra Highway and SR-14 Southbound Ramps, Sierra Highway and Placerita Canyon Road, SR-14 Northbound Ramps and Placerita Canyon Road, SR-14 Southbound Ramps and Newhall Avenue. The same mitigation measures presented for the Proposed Project would generally be necessary to accommodate the anticipated Year 2019 traffic and reduce potential impacts for the Alternative 1 Project and Alternative 2 Project. Alternative 1 Project would not require implementation of mitigation measures 4.9-5 and 4.9-10, as compared to the Proposed Project. Alternative 2 would not require implementation of mitigation measures 4.9-2. 4.9-4 and 4.9-5, as compared to the Proposed Project. Future (2035) Conditions As presented in Table 6.3-2 under Future Year 2035 with Alternative 1 Project Condition, several of the study intersections are anticipated to operate at LOS F. There are four intersections that are anticipated to operate at LOS F, they are: Sierra Highway and Placerita Canyon Road, Sierra Highway and Newhall Avenue, Valle Del Oro and Dockweiler Drive, and Main Street and Newhall Avenue. Similar to the Proposed Project, mitigation measures are necessary to accommodate the anticipated Future Year 2035 traffic and reduce potential Alternative 1 Project impacts. As presented in Table 6.4-2 under Future Year 2035 with Alternative 2 Project Condition, several of the study intersections are anticipated to operate at LOS F. There are five intersections that are anticipated to operate at LOS F, they are: Sierra Highway and Placerita Canyon Road, Sierra Highway and Newhall Avenue, Valle Del Oro and Dockweiler Drive, Railroad Avenue and 13a' Street, and Main Street and Newhall Avenue. Mitigation measures are necessary to accommodate the anticipated Future Year 2035 traffic and reduce potential Alternative 2 Project impacts With the implementation of the mitigation measures identified in Section 6.3 and 6.4, the Alternative 1 Project and Alternative 2 Project's impacts during the 2035 year will be less than significant. Therefore, the Proposed Project and two alternatives would both result in a less than significant impact after mitigation. Railroad Crossing Analysis As presented in Table 6.3-3 under Alternative 1 Year 2019, the total average daily traffic is anticipated to be highest for the No Build Condition. Alternative 1 total average daily traffic is lower than the No Build condition but higher than the Proposed Project condition. As presented in Tables 6.3-3 and 6.4-3, the total average daily railroad crossings is anticipated to be lowest for the Alternative 2 Project condition in Year 2019. In 2019, Alternative 2 would result in 820 fewer crossings than the proposed Project and 3,160 fewer crossings than Alternative 1. For the Year 2035 buildout scenario, the total average daily railroad Lyons Avenue/Dockweiler Drive Extension Project 6.5 Environmentally Superior Alternative SCH No. 2013082016 Page 6.5-6 City of Santa Clarita August 2017 crossings is also anticipated to be lowest for the Alternative 2 Project condition. In 2035, Alternative 2 would result in 6,230 fewer crossings than the proposed Project and 8,740 fewer crossings as compared to Alternative 1. As such the Alternative 2 alignment would minimize railroad crossing events and would therefore be environmentally superior to the proposed Project. Bicycle and Pedestrian Facilities Similar to the Proposed Project, both the Alternative 1 and Alternative 2 would comply with Santa Clarita's circulation goals and enhancing the circulation system by providing bicycle lanes and accessibility to bicycle paths that are fundamental for a comprehensive transportation network.

The Project is located at the intersection of Lyons Avenue and Railroad Avenue and extends eastward towards the General Plan alignment for Dockweiler Drive towards The Master's College. The Project also includes the potential upgrade or closure of an at -grade crossing at the intersection of Railroad Avenue and 131h Street. The limits for the Lyons Avenue/Dockweiler Drive extension ("Project Site') are from Railroad Avenue on the west to the future Master's College Master Plan Dockweiler extension to the east (see Figure 1, Project Location Map). Project Proponent: City of Santa Clarita General Plan Designation: Specific Plan (SP) and Mixed Use Neighborhood (MXN) Zoning Designation: SP and MXN Project Description: The Lyons Avenue/Dockweiler Drive extension is proposed to be one of the primary east -west arterials through the City of Santa Clarita that would provide a through connection from Sierra Highway to Railroad Avenue. The Lyons Avenue and Dockweiler Drive extension is being coordinated by the City of Santa Clarita to improve circulation and access to the Placerita Canyon and Newhall Community. The Project includes the extension of Lyons Avenue from Railroad Avenue to the future connection with Dockweiler Drive at the Master's College site (The Master's College extension of Dockweiler Drive through the Master's College property was evaluated under a separate EIR). The Project will include reprofiling the intersection of Lyons Avenue and Railroad Avenue to allow the construction of a new SCRRA/UP railroad grade crossing east of Railroad Avenue. The new Lyons Avenue railroad grade crossing will improve traffic movements and safety at the railroad crossing. The City anticipates the Project may also include the potential upgrade or closure of an at -grade crossing at the intersection of Railroad Avenue and 131h Street. The Lyons Avenue/Dockweiler Road Extension Project will span the Newhall Creek. The roadway construction will construct a new bridge across Newhall Creek and provide embankment protection to the roadway and creek to allow the design flood to pass Lyons Avenue. The Newhall Creek improvements will be designed in accordance with current regulatory and State permitting agencies. The extension of the proposed roadway (Lyons Avenue) was previously designated as a Major Lyons Avenue/Dockweiler Drive Extension Page 1 of 22 .,, :f;=;, ., Clarity August 233 Highway p(,,=r ,he City of Santa Clarita`s Cameral Plan, however as pa-, al aojprravz,d Master's Master Plan, Doc.icweiler Drive has been re -designated as a four lar.�: secon1ii- hi hr ry Tllf.. proposed Project will be approximately 0-40 miles in length and Wou d inCIL11JO a tour -lane: failiiy With 12-foot raised lan€iscapod rnedir)n, and a 13-Foot Par;:tivD ;i_t-fuot birlcwdlk ,and '}-foot parkway) on each side.

A "No Impact" answer is adequately supported if the referenced information sources show that the impact simply does not apply to projects like the one involved (e.g., the project falls outside a fault rupture zone). A "No Impact" answer should be explained where it is based on project -specific factors as well as general standards (e.g., the project will not expose sensitive receptors to pollutants based on a project -specific screening analysis). 2) All answers must take account of the whole action involved, including off -site as well as on -site, cumulative as well as project -level, indirect as well as direct, and construction as well as operational impacts. 3) Once the lead agency has determined that a particular physical impact may occur, then the checklist answers must indicate whether the impact is potentially significant, less that significant with mitigation, or less than significant. "Potentially Significant Impact" is appropriate if there is substantial evidence that an effect may be significant. If there are one or more "Potentially Significant Impact" entries when the determination is made, an EIR is required. 4) "Negative Declaration: Less Than Significant With Mitigation Incorporated" applies where the incorporation of a mitigation measure has reduced an effect from "Potentially Significant Impact" to "Less Than Significant Impact." The lead agency must describe the mitigation measures, and briefly explain how they reduce the effect to a less than significant level (mitigation measures from Section XVII, "Earlier Analysis," cross referenced). 5) Earlier analysis must be used where, pursuant to the tiering, program EIR, or other CEQA process, an effect has been adequately analyzed in an earlier EIR, or negative declaration. Section 15063 (c)(3)(D). In this case, a brief discussion should identify the following: 1) Earlier Analyses Used. Identify and state where they are available for review. 2) Impacts Adequately Addressed. Identify which effects from the checklist below were within the scope of and adequately analyzed in an earlier document pursuant to applicable legal standards, and state whether such effects were addressed by mitigation measures based on the earlier analysis. 3) Mitigation Measures. For effects that are "Less Than Significant With Mitigation Measures Incorporated," describe the mitigation measures which were incorporated or refined from the earlier document and the extent to which they address site -specific conditions for the project. 6) Lead agencies are encouraged to incorporate into the checklist references to information sources for potential impacts (e.g., general plans, zoning ordinances). Reference to a previously prepared or outside document should, where appropriate, include a reference to the page or pages where the statement is substantiated 7) Supporting Information Sources: A sources list should be attached, and other sources used or individuals contacted should be cited in the discussion. 8) This is only a suggested form, and lead agencies are free to use different formats; however, lead agencies should normally address the questions from this checklist that are relevant to a project's environmental effects in whichever format is selected. 9) The explanation of each issue should identify: Lyons Avenue/Dockweiler Drive Extension Page 3 of 22 City of Santa Clarita August 2013 1) The significance criteria or threshold, if any, used to evaluate each question; and 2) The mitigation measure identified, if any, to reduce the impact to less than significance. ENVIRONMENTAL FACTORS POTENTIALLY AFFECTED: The environmental factors checked below would be potentially affected by this project, involving at least one impact that is a "Potentially Significant Impact" as indicated by the checklist on the following pages. Q Aesthetics ❑ Agricultural and Forestry Resources Q Air Quality Q Biological Resources Q Cultural Resources 0 Geology/Soils ENVIRONMENTAL IMPACTS I. AESTHETICS.

Create a new source of substantial light or glare which would 1Z ❑ ❑ ❑ adversely affect day or nighttime views in the area? Lyons Avenue/Dockweiler Drive Extension Page 4 of 22 City of Santa Clarita August 2013 Responses a-d: Potentially Significant Impact. The Project will involve grading and re -contouring of undeveloped land that is over and east of Newhall Creek at Lyons Avenue. The Project will include the development of a new roadway connection with street lighting. The Project would not affect a designated scenic area. However, the Project site is visible from the downtown Newhall area from Lyons Avenue and along Railroad Avenue and from several residential properties within Placerita Canyon. As such, the Project has the potential to alter the aesthetic character of a currently undeveloped area, including a ridgeline. The ridgeline located to the east of the Project limits is designated as a Significant Ridgeline in the City's General Plan.' A Ridgeline Alteration Permit was granted by the City Council in 2009 as a part of the Master's College Master Plan approval. Thus, the Project's potential impacts upon views, aesthetics, and light and glare will be evaluated in greater detail within the scope of the EIR. II. AGRICULTURAL RESOURCES. In determining whether impacts to agricultural resources are significant environmental effects, lead agencies may refer to the California Agricultural Land Evaluation and Site Assessment Model (1997) prepared by the California Department of Conservation as an optional model to use in assessing impacts on agriculture and farmland. In determining whether impacts to forest resources, including timberland, are significant environmental effects, lead agencies may refer to information compiled by the California Department of Forestry and Fire Protection regarding the state's inventory of forest land, including the Forest Range and Assessment Project and Forest Legacy Assessment project; and forest carbon measurement methodology provided in Forest Protocols adopted by the California Air Resources Board. Would the project: a. Convert Prime Farmland, Unique Farmland, or Farmland of Statewide Importance, as shown on the maps prepared pursuant to the Farmland Mapping and Monitoring Program of the California Resources Agency, to non-agricultural use? b. Conflict the existing zoning for agricultural use, or a Williamson Act Contract? Less Than Significant Potentially with Less Than Significant Mitigation Significant Impact Incorporated Impact ❑ ❑ ❑ ❑ ❑ ❑ C. Conflict with existing zoning for, or cause rezoning of, forest ❑ land (as defined by Public Resources Code section 12220(g)), timberland (as defined by Public Resources Code section 4526, or timberland zoned Timberland Production (as defined by Government Code section 51104 (g)?

Involve other changes in the existing environment which, due ❑ ❑ ❑ 1Z to their location or nature, could result in conversion of Farmland, to non-agricultural use? Responses a-e. No Impact. A significant impact may occur if the Project were to result in the conversion of state -designated agricultural land from agricultural use to another non-agricultural use, the conversion of land zoned for agricultural use or under a Williamson Act contract from agricultural use to another non-agricultural use, results in the rezoning of forest land s Data Source: Ridgelines, City of Santa Clarita Planning, 1991. USGS 30m DEMs Description: Map showing Significant Ridgelines as identified by the 1991 General Plan. Lyons Avenue/Dockweiler Drive Extension Page 5 of 22 City of Santa Clarita August 2013 or timberland, or involves other changes in the existing environment which, could result in conversion of Farmland, to non- agricultural use. The Project Area contains the following land use and zoning designations: "SP(3)" (Downtown Newhall Specific Plan) and MXN (Mixed Use Neighborhood). Therefore, the Project site would have no impact associated with the conversion of agricultural uses or forested lands. No further analysis of this issue is required. Less Than III. AIR QUALITY. Where applicable, the significance criteria Significant established by the South Coast Air Quality Management District Potentially with Less Than (SCAQMD) may be relied upon to make the following Significant Mitigation Significant determinations. Would the project result in: Impact Incorporated Impact No Impact a. Conflict with or obstruct implementation of the SCAQMD Air 1Z ❑ ❑ ❑ Quality Management Plan or Congestion Management Plan? b. Violate any air quality standard or contribute substantially to 1Z ❑ ❑ ❑ an existing or projected air quality violation? c. Result in a cumulatively considerable net increase of any 1Z ❑ ❑ ❑ criteria pollutant for which the air basin is non -attainment under an applicable federal or state ambient air quality standard (including releasing emissions which exceed quantitative thresholds for ozone precursors)? d. Expose sensitive receptors to substantial pollutant 1Z ❑ ❑ ❑ concentrations? e. Create objectionable odors affecting a substantial number of ❑ ❑ 1Z ❑ people? Responses a-d. Potentially Significant Impact. A significant impact could occur if the Project is not consistent with the applicable Air Quality Management Plan (AQMP) and/or if implementation of the Project creates a substantial hindrance to the policies or goals of the AQMP. The project will involve the use of heavy construction equipment for grading and excavation and, as such, has the potential to generate air pollution from combustible gas and diesel engines. Operation of the Project would not increase the number of vehicle trips of the road, but will alter the pattern of traffic flow within the City. Therefore, the construction and operational air quality emissions will be quantified and analyzed in the EIR. Response e. Less Than Significant Impact. A significant impact may occur if objectionable odors occur which would adversely impact sensitive receptors. Odors are typically associated with the use of chemicals, solvents, petroleum products, and other strong -smelling elements used in manufacturing processes. The Project involves the expansion of a roadway and the potential upgrade or closure of a railroad crossing. No activities with the potential for generating odors would be involved with the long-term operation of the Project. Therefore, the potential for the Project to result in objectionable odors is less than significant and no further analysis is this issue is warranted. IV. BIOLOGICAL RESOURCES. Would the project: a. Have a substantial adverse effect, either directly or through habitat modification, on any species identified as a candidate, sensitive, or special status species in local or regional plans, policies, or regulations by the California Department of Fish and Game or U.S. Fish and Wildlife Service?

Affect a Significant Ecological Area (SEA) or Significant Natural ❑ ❑ ❑ 1z Area (SNA) as identified on the City of Santa Clarita ESA Delineation Map? Response a-f: Potentially Significant Impact. The existing Project site consists of improved segments of Lyons Avenue and Railroad Avenue roadways and undeveloped land to the east extending towards Dockweiler Drive. The Project Area encompasses portions of Newhall Creek and the proposed Project would include the construction of a structural bridge crossing over Newhall Creek. Accordingly, the EIR will include a detailed biological assessment of the vegetation and species that are known and presumed to occur within the Project's area of impact. The biological assessment will determine the extent of jurisdictional lands present on site that are subject to the permitting authority of the Army Corps. of Engineers (ACOE), U.S. Fish and Wildlife Service (USFWS), and/or the California Department of Fish and Game (CDFG). Thus, the Project's potential to result in a substantial adverse effect, either directly or through habitat modification, on any species identified as a candidate, sensitive, or special status species in local or regional plans, policies, or regulations by the CDFG or USFWS will be evaluated within the scope of the EIR. Response to g: No Impact. A significant impact may occur if a project is located within the Significant Ecological Area or Significant Natural Area as identified on the City of Santa Clarita ESA Delineation Map. The Project site is not located within the Significant Ecological Area or Significant Natural Area as identified on Exhibit CO-5 of the City's General Plan, and therefore, no impact would occur. V. CULTURAL RESOURCES: Would the project: a. Cause a substantial adverse change in significance of a historical resource as defined in State CEQA §15064.5? Less Than Significant Potentially with Less Than Significant Mitigation Significant Impact Incorporated Impact ❑ ❑ ❑ No Impact 161 Lyons Avenue/Dockweiler Drive Extension Page 7 of 22 City of Santa Clarita August 2013 b. Cause a substantial adverse change in significance of an 1z archaeological resource pursuant to State CEQA §15064.5? c. Directly or indirectly destroy a unique paleontological resource 1z or site or unique geologic feature? d. Disturb any human remains, including those interred outside 1z of formal cemeteries? Response a. No Impact. A project that may cause a substantial adverse change in the significance of a historical resource is a project that may have a significant effect on the environment. There are no habitable structures located within the Project site. The Project site consists of improved roadway segments and undeveloped open space areas. Therefore, the Project would not have the potential to adversely impact any historic resources. Response b-d. Potentially Significant Impact. Section 15064.5 of the State CEQA Guidelines defines significant archaeological resources as resources that meet the criteria for historical resources, as discussed above, or resources that constitute unique archaeological resources. A project -related significant adverse effect could occur if the Project were to affect archaeological or paleontological resources, which fall under either of these categories. A significant adverse effect could also occur if grading or excavation activities associated with the Project were to disturb previously interred human remains. Although portions of the Project site are improved with roadways, the Project will include earthwork activities in areas that are currently undeveloped. As such, it is likely that the Project's earthwork activities may result in the accidental discovery of prehistoric or historic archaeological resources that may be located within the Project limits. The EIR will include a records search to determine whether any archaeological resources, paleontological resources, or native American burial sites occur within the project area. Precautionary mitigation measures will be recommended, as appropriate, to ensure that if such resources are encountered, proper procedures would be implemented to mitigate any potential adverse impacts.

A significant impact may occur if the Project is located within a State - designated Alquist-Priolo Zone or other designated fault zone, and appropriate building practices are not employed. Based on the City of Santa Clarita, Seismic Hazards Zone Map, the Project site is not located on or adjacent to a known mapped fault line or within a designated Alquist-Priolo Zone .Z The Project site is located within the vicinity of a mapped Earthquake Induced Landslide Hazard Zone .3 The Project will include a substantial amount of earthwork and grading activities to realign and extend an existing roadway through a currently undeveloped area. The Project would also include a bridge crossing over the Newhall Creek. As such, a site -specific soils and geotechnical investigation will be prepared to evaluate the suitability of the site to support the roadway infrastructure being planned. Further detailed analysis to address geotechnical engineering and safety issues will be included within the scope of the EIR. Response e: No Impact. This question would apply to the Project only if it generated a demand for sewer conveyance or treatment systems. The Project consists of a roadway infrastructure project and will not generate any wastewater effluent. No habitable structures are proposed. Therefore, no impact would occur and no further analysis is required. Z Data Source: City of Santa Clarita, Seismic Hazard Zones Map, map update as of September 2012. 3 Ibid. Lyons Avenue/Dockweiler Drive Extension Page 9 of 22 City of Santa Clarita August 2013 Response f-i: Potentially Significant Impact. A significant impact may occur if the Project results in a change in topography, requires earth movement of 10,000 cubic yards or more, development or grading on a slope greater than 10%, or the disturbance of unique geological or physical features. The Project will include a substantial amount of earthwork and grading activities to realign and extend an existing roadway through a currently undeveloped area. The Project would also include a bridge crossing over the Newhall Creek. Accordingly, further detailed analysis to address topography, earth movement, grading and disturbance of unique geological and physical features issues will be included within the scope of the EIR. Less Than Significant Potentially with Less Than VII. GREENHOUSE GAS EMISSIONS Significant Mitigation Significant Would the project: Impact Incorporated Impact No Impact a. Generate greenhouse gas emissions, either directly or L3 L3 1Z indirectly, that may have a significant impact upon the environment? b. Conflict with an applicable plan, policy or regulation adopted L3 L3 1Z for the purpose of reducing the emissions of greenhouse gasses? Responses a-b: Less than Significant Impact. On August 28, 2012, the City of Santa Clarita adopted a Climate Action Plan (CAP), which provides policies and identifies actions intended to reduce GHG emissions within the City and assist in the fight against Climate Change. Overall the goal of the CAP is to reduce Santa Clarita's community -wide GHG emissions below the 2005 baseline emissions by 2020. The CAP includes a set of strategies the City can use to reduce the amount of greenhouse gas emissions produced in the community. Implementation of the measures proposed in the Proposed CAP would result in an annual community -wide reduction in GHG emissions of approximately 193,000 MTCO2e by 2020 from local measures and an additional reduction of approximately 148,952 MTCO2e by 2020 from statewide measures. This would reduce GHG emissions from the Business -as -usual projections for 2020 by 17 percent and would exceed the GHG reduction targets of 16 percent established by CARB in its revised scoping plan. Implementation of the strategies identified in the CAP would also exceed the City's goal to reduce 2020 GHG emissions to a level below the 2005 GHG emissions baseline by 4 percent. The CAP defines a local threshold of significance for green house gas emissions (GHG) for project level submittals that are subject to environmental review under CEQA. Goals, objectives and policies approved under the General Plan are forecast to meet the GHG emission reduction targets mandated by AB 32. Therefore, development projects that are able to demonstrate consistency with the General Plan and zoning ordinance are by association consistent with the CAP and are not subject to further environmental review. Development proposals that are not consistent with the City's General Plan and/or Unified Development Code (Zone Changes/General Plan Amendments) must demonstrate a 12 percent reduction in the GHG emissions from the Controlled 2020 Business as Usual Scenario, to be deemed consistent with the CAP. Development proposals that are not consistent with the City's General Plan and/or Unified Development Code and that can not demonstrate a 12 percent reduction in GHG emissions from the Controlled Business as Usual Scenario shall be deemed to have a significant impact on GHG emissions. The Project is consistent with the Circulation Element of the General Plan and will not require a zone change or General Plan amendment. As such, the Project's potential to generate GHGs will be less than significant with respect to consistency with all applicable plans, policies or regulations adopted for the purpose of reducing the emissions of greenhouse gases, and no further analysis of this issue is warranted.

Create a significant hazard to the public or the environment through the routine transport, use, or disposal of hazardous materials? b. Create a significant hazard to the public or the environment through reasonably foreseeable upset and accident conditions involving the release of hazardous materials into the environment? c. Emit hazardous emissions or handle hazardous or acutely hazardous materials, substances, or waste within one -quarter mile of an existing or proposed school? d. Be located on a site which is included on a list of hazardous materials sites compiled pursuant to Government Code Section 65962.5 and, as a result, would it create a significant hazard to the public or the environment? e. For a project located within an airport land use plan or, where such a plan has not been adopted, within two miles of a public airport or public use airport, would the project result in a safety hazard for people residing or working in the project area? f. For a project within the vicinity of a private airstrip, would the project result in a safety hazard for the people residing or working in the area? g. Impair implementation of or physically interfere with an adopted emergency response plan or emergency evacuation plan? h. Expose people or structures to a significant risk of loss, injury or death involving wildland fires, including where wildlands are adjacent to urbanized areas or where residences are intermixed with wildlands?

Exposure of people to existing sources of potential health hazards (e.g. electrical transmission lines, gas lines, oil pipelines)? ❑ ❑ ❑ Q Response a-c: Less Than Significant Impact. A significant impact may occur if a project involves the use or disposal of hazardous materials as part of its routine operations which may have the potential to generate toxic or otherwise hazardous emissions that could adversely affect sensitive receptors. Since the Project would not require the transport, use, and/or disposal of potentially hazardous materials, the potential for an impact to occur is considered low. Therefore, further analysis of this issue in an EIR is not warranted. Lyons Avenue/Dockweiler Drive Extension Page 11 of 22 City of Santa Clarita August 2013 Response d: Less Than Significant Impact. California Government Code Section 65962.5 requires various state agencies to compile lists of hazardous waste disposal facilities, unauthorized releases from underground storage tanks, contaminated drinking water wells and solid waste facilities from which there is known migration of hazardous waste and submit such information to the Secretary for Environmental Protection on at least an annual basis. No properties within or immediately adjacent to the Project site appear on the State's list of hazardous materials sites. Therefore, further analysis of this issue is not warranted. Responses e & f: No Impact. The Project is not located near a private airstrip. No impacts involving airports would occur, and no further analysis is required. Response g: Less Than Significant Impact. A significant impact may occur if a project were to interfere with roadway operations used in conjunction with an emergency response plan or emergency evacuation plan or would generate traffic congestion that would interfere with the execution of such a plan. Construction of the Project involves buildout of a roadway extension that was identified in the City's Circulation Element of the General Plan. As the proposed Project would be consistent with the City's adopted Circulation Element, the Project would not impair implementation of or physically interfere with an adopted emergency response plan or emergency evacuation plan. Impacts would be less than significant. Response h: Less Than Significant Impact. A significant impact may occur if a project is located in proximity to wildland areas and poses a potential fire hazard, which could affect persons or structures in the area in the event of a fire. The Project does not include the construction of any habitable structures. Therefore, no further analysis of this issue is warranted. Response is No Impact. The site is not known or expected to contain any electrical transmission lines, gas lines, oil lines, or other hazardous material conduits or storage facilities. Therefore, the proposed project would not expose people to existing sources of potential health hazards, and the project would have no related impacts. Therefore, no further analysis of this issue is warranted. Less Than Significant Potentially with Less Than IX. HYDROLOGY AND WATER QUALITY.

Storm water discharges that would significantly impair or 1Z contribute to the impairment of the beneficial uses of receiving waters or areas that provide water quality benefits (e.g. riparian Lyons Avenue/Dockweiler Drive Extension Page 13 of 22 City of Santa Clarita August 2013 corridors, wetlands, etc.) vi, Cause harm to the biological integrity of drainage systems, 1Z watersheds, and/or water bodies? vii, Does the proposed project include provisions for the 1Z separation, recycling, and reuse of materials both during construction and after project occupancy? Response a-f: Potentially Significant Impact. A significant impact may occur if a project discharges water which does not meet the quality standards of agencies that regulate surface water quality and water discharge into storm water drainage systems. Significant impacts would also occur if a project does not comply with all applicable regulations with regard to surface water quality as governed by the State Water Resources Control Board (SWRCB). The Project involves the development of a roadway extension and bridge alignment over Newhall Creek. The Project will involve a substantial amount of earthwork and grading which has the potential to alter the hydrological conditions within the Project Area and downstream from the Project site. The project's potential to violate any water quality standards or waste discharge requirements will be further analyzed in an EIR. Response g-i: No Impact. The Project does not involve the construction of any habitable structures. Therefore, the Project would not place housing within an area susceptible to flooding or mudflows. No impact would occur and no further analysis of this issue is required. Response j: Potentially Significant Impact. The Project includes a planned roadway extension with a bridge crossing over Newhall Creek. As such, detailed hydrologic studies will be included in the EIR to determine the potential risk of mudflow both upstream and downstream of the Project site. Response k-m: Potentially Significant Impact. A significant impact may occur if a project changes the flow, current, course, or direction of surface or groundwater, modifies a wash, channel creek or river, or impacts Stormwater Management. The Project includes a planned roadway extension with a bridge crossing over Newhall Creek. As such, detailed hydrologic studies will be included in the EIR to determine the potential impacts associated with the hydrology of the Project site.

Conflict with any applicable habitat conservation plan or 1Z natural community conservation plan? Lyons Avenue/Dockweiler Drive Extension Page 14 of 22 City of Santa Clarita August 2013 Response a: Potentially Significant Impact. A significant impact may occur if a project were sufficiently large enough or otherwise configured in such a way as to create a physical barrier within an established community (a typical example would be a project that involved a continuous right-of-way such as a roadway which would divide a community and impede access between parts of the community). The proposed roadway extension, addition of a CPUC railroad crossing and the potential upgrade or closure of an existing at grade crossing at 131h Street will alter the access and circulation system affecting the Placerita Canyon homeowners. Accordingly, this issue will be further evaluated within the EIR. Response b: Potentially Significant Impact. A significant impact may occur if a project is inconsistent with the Circulation Element of the General Plan. The proposed Dockweiler Drive extension to Lyons Avenue was identified in the City's Circulation Element of the General Plan. Nevertheless, the EIR will provide additional analysis to assess the Project's consistency with applicable General Plan policies, zoning code restrictions, Southern California Association of Governments (SCAG) policies, any other applicable City or County plans, and any required mitigation measures. Response c: Potentially Significant Impact. As discussed in Question IV(f) above, the Project's potential to conflict with any applicable habitat conservation plan or natural community conservation plan will be evaluated within the EIR. XI. MINERAL RESOURCES. Would the project: a. Result in the loss of availability of a known mineral resource that would be of value to the region and the residents of the state? b. Result in the loss of availability of a locally -important mineral resource recovery site delineated on a local general plan, specific plan, or other land use plan? c. Use nonrenewable resources in a wasteful and inefficient manner? Less Than Significant Potentially with Less Than Significant Mitigation Significant Impact Incorporated Impact ❑ ❑ 1Z ❑ ❑ ❑ ❑ No Impact Response a-b: Less Than Significant Impact. The Project is not located near any oil fields and no oil extraction activities have historically occurred on or are presently conducted at the Project site. Furthermore, the Project site is not in an area identified by the City of Santa Clarita as containing a significant mineral deposits site that would be of value to the region and the residents of the state. Therefore, no impact would occur to mineral resources and no further analysis of this issue is required. Response c: Less Than Significant Impact. Nonrenewable resources associated with building materials will be utilized during the construction and operational phases of the Project. The project would utilize building materials and nonrenewable resources for construction of the proposed bridge and roadway alignment. Many of the resources utilized for construction are nonrenewable, including sand, gravel, earth, iron, steel, and hardscape materials. Other construction resources that are expected to be used, such as lumber, are slowly renewable resources. In addition, the Project would commit energy and water resources as a result of the construction, operation, and maintenance of the proposed development. Much of the energy that will be utilized on -site will be generated through combustion of fossil fuels, which are nonrenewable resources. Market -rate conditions encourage the efficient use of raw materials and non-renewable Lyons Avenue/Dockweiler Drive Extension Page 15 of 22 City of Santa Clarita August 2013 resources during construction. Similarly, the energy and water resources that would be utilized by the Project would be minimal and would be supplied by the regional utility purveyors, which participate in various conservation programs. Water would only be used during construction. The Project would utilize a minimal amount energy as needed for roadway lighting. Therefore, the proposed project would not use nonrenewable resources in a wasteful and inefficient manner, and the project would have no related significant impacts. XII. NOISE. Would the project: a. Exposure of persons to or generation of noise in level in excess of standards established in the local general plan or noise ordinance, or applicable standards of other agencies? b. Exposure of people to or generation of excessive groundborne vibration or groundborne noise levels? c.

For a project within the vicinity of a private airstrip, would the ❑ project expose people residing or working in the project area to excessive noise levels? No Impact 1Z 1Z Response a-d: Potentially Significant Impact. A significant impact would occur if the Project exposes people to or generated excessive groundborne vibration or groundborne noise levels. Construction of the Project would require the use of construction equipment during grading, hauling, establishing structural foundations, installation of utility lines and services, and other construction activities. Construction of the Project has the potential to generate groundborne vibration that could impact surrounding uses and sensitive receptors, specifically with respect to the neighboring Placerita Canyon and Downtown Newhall communities. The Project's potential to generate both short-term construction related impacts and long-term operational noise impacts to the surrounding land uses will be evaluated within the EIR. Response a-f: No Impact. A significant impact may occur if the Project were located within an airport land use plan and would introduce substantial new sources of noise or substantially add to existing sources of noise within or near the Project site. The Project site is not located within two miles of a public or private airport or airstrip. Therefore, no impact would occur and no further analysis of this issue is required.

Displace substantial numbers of existing housing necessitating L3 L3 L3 1z the construction of replacement housing elsewhere? c. Displace substantial numbers of people necessitating the L3 L3 L3 1z construction of replacement housing elsewhere? Response a: No Impact. A significant impact may occur if a project were to locate new development such as homes, businesses, or infrastructure, with the effect of substantially inducing population growth that would otherwise not have occurred as rapidly or in as great a magnitude. The Project involved the buildout of a proposed roadway alignment that was identified within the City's Circulation Element of the General Plan. No residential, commercial ,or industrial land uses are proposed. Therefore, the Project would not have the potential to induce substantial population growth in an area either directly. Response b-c: No Impact. A significant impact may occur if a project would result in displacement of existing housing, necessitating construction of replacement housing elsewhere. The Project would not displace any existing housing units, necessitating the construction of replacement housing elsewhere. Therefore, no impact would occur and no further analysis is required. XIV.

A significant impact may occur if the County of Los Angeles Fire Department (LACoFD) and Los Angeles County Sherriffs Department (LASD) could not adequately serve the areas affected by the Project's circulation plan based upon response time, access, or fire hydrant/water availability. The Project would not directly increase the demands for fire and police protection as the Project does not include any new housing units or commercial uses. Emergency access to the Placerita Canyon community would be facilitated through the Project's alignment, which is consistent with the City's adopted Circulation Element. The Project's alignment would be an improvement to the current access route into the Placerita Canyon community via 131h Street. The potential upgrade or closure of the 131h Street at -grade crossing is a proposed safety feature aimed at reducing potential conflicts between pedestrians, vehicles and trains. The Project's impact upon fire and police services would be less than significant and no further analysis is warranted. Schools: No Impact. A significant impact may occur if a project includes substantial employment or population growth, which could generate a demand for school facilities that would exceed the capacity of the local school District. The Project would not directly impact any local schools as the Project does not include any new housing units. The Project would not have any impact upon schools. Thus, no further analysis of school capacity is warranted. Parks: No Impact. A significant impact may occur if a project includes substantial employment or population growth, which could generate a demand for park and recreation facilities that would result in the need to construct park and recreation facilities to accommodate the Project. The Project would not directly impact any local park and/or recreational facility, as the Project does not include any new housing units or commercial uses.

A significant impact would occur if a project exceeds wastewater treatment requirements of the applicable Regional Water Quality Control Board or increase water consumption or wastewater generation to such a degree that the capacities of facilities currently serving the Project site would be exceeded. The Project does not include the construction of any habitable uses and would not require any connections to a sanitary sewer. Thus, no impact to wastewater treatment facilities would be created and no further analysis of this issue is warranted. Response c: Less Than Significant Impact. The drainage system of the Project will be developed so that post development peak runoff discharge rates are equal or less than pre development peak runoff rates, as required by the City of Santa Clarita and the Countywide MS4 Permit. As such, the Project would not result in the construction of new stormwater drainage facilities or expansion of existing facilities and no further analysis is warranted. Response d: No Impact. A significant impact may occur if a project were to increase water consumption to such a degree Lyons Avenue/Dockweiler Drive Extension Page 20 of 22 City of Santa Clarita August 2013 that new water sources would need to be identified, or that existing resources would be consumed at a pace greater than planned for by purveyors, distributors, and service providers. The Project does not include the construction f any habitable uses and would not create a demand for potable water. Thus, no impact to water resources would occur and no further analysis of this issue is warranted. Response e: No Impact. A significant impact may occur if a project would increase wastewater generation to such a degree that the capacity of facilities currently serving the Project site would be exceeded. The Project does not include the construction of any habitable uses and would not require any connections to a sanitary sewer. Thus, no impact to wastewater treatment facilities would be created and no further analysis of this issue is warranted. Response f: Less Than Significant Impact. A significant impact may occur if a project were to increase solid waste generation to a degree such that the existing and projected landfill capacity would be insufficient to accommodate the additional solid waste. The Project does not include the construction of any habitable uses and would not generate a demand for solid waste resources. No further analysis of this issue is warranted. Response g: No Impact. A significant impact may occur if a project would generate solid waste that was not disposed of in accordance with applicable regulations. The Project will comply with all federal, State, and local statutes and regulations related to solid waste generated during the construction phase. The Project does not include the construction of any habitable uses and would not generate a demand for solid waste resources on an ongoing basis during the life of the Project. No further analysis of this issue is warranted. Less Than Significant Potentially with Less Than Significant Mitigation Significant XVIII. MANDATORY FINDINGS OF SIGNIFICANCE. Impact Incorporated Impact No Impact a. Does the project have the potential to degrade the quality of 1z the environment, substantially reduce the habitat of fish or wildlife species, cause a fish or wildlife population to drop below self-sustaining levels, threaten to eliminate a plant or animal community, reduce the number or restrict the range of a rare or endangered plant or animal or eliminate important examples of the major periods of California history or prehistory? b. Does the project have impacts which are individually limited, 1z but cumulatively considerable? ("Cumulatively considerable" means that the incremental effects of an individual project are considerable when viewed in connection with the effects of past projects, the effects of other current projects, and the effects of probable future projects). c. Does the project have environmental effects, which cause 1z substantial adverse effects on human beings, either directly or indirectly? Responses a-c: Potentially Significant Impact. A significant impact may occur if a project would degrade the quality of the environment, substantially reduce the habitat of a fish or wildlife species, cause a fish or wildlife population to drop below Lyons Avenue/Dockweiler Drive Extension Page 21 of 22 City of Santa Clarita August 2013 self-sustaining levels, threaten to eliminate a plant or animal community, reduce the number or restrict the range of a rare or endangered plant or animal or eliminate important examples of the major periods of California history or prehistory. The Project will involve the grading and disturbance of land that is currently undeveloped. The planned roadway extension will cross Newhall Creek, which is an intermittent streambed. Thus the Project has the potential to impact riparian and upland habitat and sensitive species. Accordingly, the Project's potential to substantially reduce the habitat of a fish or wildlife species, cause a fish or wildlife population to drop below self-sustaining levels, threaten to eliminate a plant or animal community, reduce the number or restrict the range of a rare or endangered plant or animal or eliminate important examples of the major periods of California history or prehistory will be evaluated within the scope of the EIR.

In the 1985 Appellate Court decision (170 Cal App 3rd 604), the court held that the NAHC has jurisdiction and special expertise, as a state agency, over affected Native American resources impacted by proposed projects, including archaeological places of religious significance to Native Americans, and to Native American burial sites. The California Environmental Quality Act (CEQA) states that any project that causes a substantial adverse change in the significance of an historical resource, which includes archeological resources, is a significant effect requiring the preparation of an EIR (CEQA guidelines 15064.5(b). To adequately comply with this provision and mitigate project -related impacts on archaeological resources, the Commission recommends the following actions be required: Contact the appropriate Information Center for a record search to determine :If a part or all of the area of project effect (APE) has been previously surveyed for cultural places(s), The NAHC recommends that known traditional cultural resources recorded on or adjacent to the APE be listed in the draft Environmental Impact Report (DEIR). If an additional archaeological inventory survey is required, the final stage is the preparation of a professional report detailing the findings and recommendations of the records search and field survey. We suggest that this be coordinated with the NAHC, if possible. The final report containing site forms, site significance, and mitigation measurers should be submitted immediately to the planning department. All information regarding site locations, Native American human remains, and associated funerary objects should be in a separate confidential addendum, and not be made available for pubic disclosure pursuant to California Government Code Section 6254.10. A list of appropriate Native American Contacts for consultation concerning the project site has been provided and is attached to this letter to determine if the proposed active might impinge on any cultural resources. Lack of surface evidence of archeological resources does not preclude their subsurface existence. Lead agencies should include in their mitigation plan provisions for the identification and evaluation of accidentally discovered archeological resources, pursuant to California Health & Safety Code Section 7050.5 and California Environmental Quality Act (CEQA) §15064.5(f). In areas of identified archaeological sensitivity, a certified archaeologist and a culturally affiliated Native American, with knowledge in cultural resources, should monitor all ground -disturbing activities. Also, California Public Resources Code Section 21083.2 require documentation and analysis of archaeological items that meet the standard in Section 15064.5 (a)(b)(f). Lead agencies should include in their mitigation plan provisions for the disposition of recovered artifacts, in consultation with culturally affiliated Native Americans. Lead agencies should include provisions for discovery of Native American human remains in their mitigation plan. Health and Safety Code §7050.5, CEQA §15064.5(e), and Public Resources Code §5097.98 mandates the process to be followed in the event of an accidental discovery of any human remains in a location other than a dedicated cemetery. 0-a-v-e Sin2gQe` Program An CC: State Clearinghouse Attachment: Native American Contacts list Native American Contacts Los Angeles County August 20, 2013 Beverly Salazar Folkes 1931 Shadybrook Drive Thousand Oaks, CA 91362 folkes9@msn.com 805 492-7255 (805) 558-1154 - cell folkes9@msn.com Chumash Tataviam Ferrnandeno Fernandeno Tataviam Band of Mission Indians Larry Ortega, Chairperson 1019 - 2nd Street, suite #1 Fernandeno San Fernando CA 91340 Tataviam (818) 837-0794 Office (818) 837-0796 Fax LA City/County Native American Indian Comm Ron Andrade, Director 3175 West 6th St, Rm. 403 Los Angeles , CA 90020 randrade@css.lacounty.gov (213) 351-5324 (213) 386-3995 FAX Kitanemuk & Yowlumne Tejon Indians Delia Dominguez, Chairperson 115 Radio Street Yowiumne Bakersfield , CA 93305 Kitanemuk deedominguez@ juno.com (626) 339-6785 This list is current only as of the date of this document.

BROWN JR., Governor CHARLTON H. BONHAM, Director Subject: Notice of Preparation for an Environment Impact Report and Public Scoping Meeting for the Proposed Lyons Avenue /Dockweiler Drive Extension Project, City of Santa Clarita, Los Angeles County Dear Mr. Hennawy: The California Department of Fish and Wildlife (Department) has received the Notice of Preparation for the Draft Environmental Impact Report (DEIR) for the proposed Lyons Avenue / Dockweiler Drive Extension Project (project). The project is located at the eastern terminus of Lyons Avenue in the City of Santa Clarita and includes the extension of Lyons Avenue from Railroad Avenue to the future connection with Dockweiler Drive at the Master's College site. The project will include re -profiling the intersection of Lyons Avenue and Railroad Avenue to allow the construction of a new railroad grade crossing east of Railroad Avenue. The project area encompasses portions of Newhall Creek and would include the construction of a structural bridge crossing over Newhall Creek. The Department is California's Trustee Agency for fish and wildlife resources, holding these resources in trust for the People of the State pursuant to various provisions of the California Fish and Game Code (Fish & G. Code, §§ 711.7, subd. (a); 1802.). The Department submits these comments in that capacity under the California Environmental Quality Act (CEQA) (See generally Pub. Resources Code, §§ 21070; 21080.4.). Given its related permitting authority under the California Endangered Species Act (CESA) and Fish and Game Code section 1600 et seq., the Department also submits these comments likely as a Responsible Agency for the project under CEQA (Pub. Resources Code, § 21069.). The California Wildlife Action Plan, a recent Department guidance document, identified the following stressors affecting wildlife and habitats within the project area: 1) growth and development; 2) water management conflicts and degradation of aquatic ecosystems; 3) invasive species; 4) altered fire regimes; and 5) recreational pressures. The Department looks forward to working with the City of Santa Clarita to minimize impacts to fish and wildlife resources with a focus on these stressors. Please let Department staff know if you would like a copy of the California Wildlife Action Plan to review. To enable Department staff to adequately review and comment on the proposed project the Department recommends the following information, where applicable, be included in the DEIR: 1. A complete, recent assessment of flora and fauna within and adjacent to the project area, with particular emphasis upon identifying endangered, threatened, and locally unique species and sensitive habitats including: Conserving Ca fornia's Wifd(fe Since 1870 Mr. Mike Hennawy, Senior Engineer City of Santa Clarita September 6, 2013 Page 3 of 5 butterfly roost sites and neo-tropical bird and waterfowl stop -over and staging sites. All migratory nongame native bird species are protected by international treaty under the Federal Migratory Bird Treaty Act (MBTA) of 1918 (50 C.F.R. § 10.13). Sections 3503, 3503.5 and 3513 of the California Fish and Game Code prohibit take of birds and their active nests, including raptors and other migratory nongame birds as listed under the MBTA e. Active Breeding and/or Nest. If the nesting season cannot be avoided and construction or vegetation removal occurs between March 1st to September 15t" (January 1st to July 31st for raptors), the Permittee will do one of the following to avoid and minimize impacts to nesting birds'; 1) Implement default 300 foot minimum avoidance buffers for all passerine birds _and 500 foot minimum avoidance buffer for all raptors species. The breeding habitat/nest site shall be fenced and/or flagged in all directions, and this area shall not be disturbed until the nest becomes inactive, the young have fledged, the young are no longer being fed by the parents, the young have left the area, and the young will no longer be impacted by the project2. 2) Develop a project specific Nesting Bird Management Plan. The site -specific nest protection plan shall be submitted to lead agency for review and the Department. The Plan should include detailed methodologies and definitions to enable a Department qualified avian biologist to monitor and implement nest -specific buffers based upon the life history of the individual species; species sensitivity to noise, vibration, and general disturbance; individual bird behavior; current site condition (screening topography, vegetation, etcetera), ambient levels of activities; and the various project -related activities necessary to construction the project. ,. This Nesting Bird Management Plan shall be supported by a Nest Log which tracks each nest and its outcome. The Nest Log will be submitted to the Lead Agency and the Department at the end of each week. 3) The Permittee may propose an alternative plan for avoidance of nesting birds for the lead agencies concurrence and the Department review. Impacts from project activities that will result in disturbances to habitat that may provide maternity roosts for bats (e.g., tree cavities, under loose bark, buildings), should occur outside of the bat breeding season which generally runs from March 1-August 31. Bats are considered non -game mammals and are afforded protection by state law from take and/or harassment, (Fish and Game Code § 4150, California Code of Regulations, § 251.1). Several bat species are also considered special status species and meet the CEQA definition of rare, threatened or endangered species (CEQA Guidelines 15065). ' Qualified avian biologist shall establish the necessary buffers to avoid take of nest as defined in FGC 3503 and 3503.5. 2 NOTE: Buffer area may be increased if any endangered, threatened, or CDFW species of special concern are identified during protocol or pre -construction presence/absence surveys. Mr. Mike Hennawy, Senior Engineer City of Santa Clarita September 6, 2013 Page 5 of 5 maps) and/or the channelization of natural and manmade drainages or conversion to subsurface drains. All wetlands and watercourses, whether intermittent, ephemeral, or perennial, must be retained and provided with substantial setbacks which preserve the riparian and aquatic habitat values and maintain their value to on -site and off -site wildlife populations. The Department recommends a minimum natural buffer of 100 feet from the outside edge of the riparian zone on each side of drainage. a. The Department also has regulatory authority with regard to activities occurring in streams or lakes that could adversely affect any fish or wildlife resource. For any activity that will divert or obstruct the natural flow, or change the bed, channel, or bank (which may include associated riparian resources) or a river or stream or use material from a streambed, the project applicant (or "entity") must provide written notification to the Department pursuant to Section1602 of the Fish -arid Game Code. __Based -on-this- notification and other information, the Department then determines whether a Lake and Streambed Alteration (LSA) Agreement is required. The Department's issuance of an LSA Agreement is a project subject to CEQA. To facilitate issuance of a LSA Agreement, if necessary, the environmental document should fully identify the potential impacts to the lake, stream or riparian resources and provide adequate avoidance, mitigation, monitoring and reporting commitments for issuance of the LSA Agreement. Early consultation is recommended, since modification of the proposed project may be required to avoid or reduce impacts to fish and wildlife resources. Again, the failure to include this analysis in the project's environmental impact report could preclude the Department from relying on the Lead Agency's analysis to issue a LSA Agreement without the Department first conducting its own analysis, as Lead Agency for subsequent or supplemental analysis for the project.

The California Public Utilities Code requires Commission approval for construction or alteration of crossings and grants the Commission exclusive power on design, alteration, and/or closure of rail crossings in California. The Commission's Rail Crossings Engineering Section (RCES) has received a copy of the Notice of Preparation (NOP) from the State Clearinghouse for the proposed City of Santa Clarita (City) Lyons Avenue and Dockweller Drive Extension project. The proposed project includes the extension of Lyons Avenue from Railroad Avenue to the future connection with Dockweller Drive. The extension will cross over the rail tracks owned by the Southern California Regional Rail Authority (SCRRA) and the Union Pacific Railroad (UPRR� Company. The project may also include the potential upgrade or closure of the at -grade 13' Street crossing. The project will increase traffic volumes not only on streets and at intersections, but also at crossings. The project will create a new crossing. Safety factors to consider include, but are not limited to, the pedestrian circulation patterns/destinations with respect to railroad right-of-way (ROW), the planning for grade separations for major thoroughfares, and improvements to existing at -grade highway -rail crossings due to increase in traffic volumes and appropriate fencing to limit the access of trespassers onto the railroad ROW. Commission Rules and Regulations The following link provides resources on the Commission's rules and regulations in regard to rail safety: http://www.cpuc.ca.gov/PUC/safety/Rail/. Any modification to an existing or proposed new crossing is subject to a number of rules and regulations involving the Commission, including: California Public Utilities Code, Sections 1201 et al, which requires Commission authority to construct rail crossings; Commission's Rules of Practice and Procedure, which details the Formal Application process for construction or modification of a public crossing; and Commission's General Order (GO) 88-B, Rules for Altering Public Highway -Rail Crossings. The design criteria for any proposed modification or new crossing construction shall comply with the following GOs: Mike Hennewy Page 2 of 36 August 29, 2013 • GO 26-D, Clearance on Railroads and Street Railroads as to Side and Overhead Structures, Parallel Tracks and Crossings; • GO 72-B, Construction and Maintenance of Crossings — Standard Types of Pavement Construction at Railroad Grade Crossings; • GO 75-D, Warning Devices for At -Grade Railroad Crossings; • GO 118, Construction, Reconstruction and Maintenance of Walkways and Control, of Vegetation Adjacent to Railroad Tracks; and • GO 128, Construction or Underground and Electrical Supply and Communication. Federal Rules and Reaulations The project shall ensure compliance with federal regulations as well, including: • Code of Federal Regulations, Title 49, Part 213 (49 CFR Part 213), Track Safety Standards; • 49 CFR Part 214 Railroad Workplace Safety; • 49 CFR Part 234, Grade Crossing Signal System; • 49 CFR Part 236, Rules Standards and Instructions Governing the Installation, Inspection Maintenance, and Repair of Signal and Train Control Systems Devices, and Appliances. Crossing Authorizations RCES staff is available for consultation on crossing safety matters. The following link provides more information on the Commission's GO 88-B and formal crossing application process: http://www.cpuc.ca.gov/PUC/safety/Rail/Crossings/formalapps.htm. 1. Formal Application A Formal Application is required for construction of all new at -grade and grade separated crossings along the corridor in accordance with the Commission's Rules of Practice and Procedure. When the project is clearly defined and prior to submission of a Formal Application, City should contact RCES staff to arrange a diagnostic meeting with Commission staff and all interested parties to discuss relevant safety issues at each proposed crossing location, if any. As part of its mission to reduce hazards associated with at -grade railroad crossings, the Commission's policy is to reduce the number of such crossings. New at -grade crossings would typically not be supported by Commission staff and long-term planning for the grade separation of the existing at -grade rail crossings should be considered. 2. GO 88-B Requests Modification (including closure) of existing rail crossings is typically authorized through the Commission's GO 88-B process. If interested parties do not reach agreement regarding proposed modifications, a Formal Application to the Commission will be required in order to obtain authorization to implement the modifications. Prior to submission of a GO 88-B request for authorization, City should arrange a diagnostic meeting with Commission staff and all interested parties to discuss relevant safety issues at Mike Hennewy Page 3 of 36 August 29, 2013 the crossing location. Commission crossing safety web page is found at this link: http://www.cpuc.ca.gov/PUC/safety/Rail/Crossings/contactrces.htm. General Safety Concerns The project will involve the construction of a new crossing and upgrade/closure of the existing at - grade 13t" Street crossing. Due to serious rail safety concerns, especially given the number of trains, their rate of speed and the volume of vehicular traffic, Commission staff recommends that any newly proposed crossing of roadways/highways by this project be grade separated to prevent vehicle/pedestrian vs. train collisions. This is the only way to guarantee no future at -grade crossing accidents. We appreciate the opportunity to provide comments on the project. We are available to meet and further discuss the comments presented herein with City, SCRRA, UPRR and other relevant parties. We hope to assist in the identification of acceptable mitigation measures that will effectively address the concerns we have identified.

ANTONOVICH Fifth District NOTICE OF PREPARATION OF DRAFT ENVIRONMENTAL IMPACT REPORT FOR THE CITY OF SANTA CLARITA LYONS AVENUE/DOCKWEILER DRIVE EXTENSION PROJECT On August 5, 2013, the City of Santa Clarita released the notice of preparation (NOP) for a Draft Environmental Impact Report (DEIR) for the proposed Lyons Avenue/Dockweiler Drive Extension Project for public review and comment. The planned DEIR will evaluate the impacts of the proposed construction of a new railroad grade crossing, traffic improvements, new bridge across Newhall Creek, and joining existing roadways in the Placerita Canyon and Newhall communities. Included in this letter are comments on behalf of the County Department of Public Works and the County of Los Angeles Fire Department. Department of Public Works (DPW) Hydrology/Water Quality The DEIR must address possible impacts of the project on any Los Angeles County Flood Control District facilities. In addition, the DEIR must identify any pollutants that may be discharged into the flood control,system and provide measures to prevent such discharges. If you have any questions regarding these items, please contact Juan Sarda of the Watershed Management Division at (626) 458-5911, or via e-mail at jsarda(a-)dpw.lacounty.gov. "To Enrich Lives Through Effective And Caring Service" Please Conserve Paper— This Document and Copies are Two -Sided Infra -County Correspondence Sent Electronically Only Mike Hennawy September 3, 2013 Page 2 DPW will review the DEIR's hydrology study for any impacts from the project. If you have any questions regarding hydrology impacts, please contact Toan Duong of the Land Development Division at (626) 458-4910, or via e-mail at tduonq(a-)dpw.lacounty.gov. Transportation/Traffic DPW Traffic Studies is concerned about the potential increase in traffic expected to be generated by the project at the County -maintained intersection of Pico Canyon Road and The Old Road, and requests that the DEIR study this intersection. Since Lyons Avenue becomes Pico Canyon Road upon crossing the 1-5 freeway, the Lyons Avenue extension to Dockweiler Drive will provide a more direct connection between the northeast portion of the Santa Clarita Valley to Stevenson Ranch and the retail centers in the vicinity of the intersection. In addition, the extension may also provide a bypass route for motorists wanting to avoid the southbound SR-14 Freeway to the northbound 1-5 Freeway interchange to access the Stevenson Ranch area and adjacent retail uses. Traffic Studies also requests that the DEIR study the intersection of The Old Road at the 1-5 Freeway Southbound ramps, which is located within the County, but it is maintained by Caltrans.

General Safety Concerns The project will involve the construction of a new crossing and upgrade/closure of the existing at - grade 13th Street crossing. Due to serious rail safety concerns, especially given the number of trains, their rate of speed and the volume of vehicular traffic, Commission staff recommends that any newly proposed crossing of roadways/highways by this project be grade separated to prevent vehicle/pedestrian vs. train collisions. This is the only way to guarantee no future at -grade crossing accidents. We appreciate the opportunity to provide comments on the project. We are available to meet and further discuss the comments presented herein with City, SCRRA, UPRR and other relevant parties. We hope to assist in the identification of acceptable mitigation measures that will effectively address the concerns we have identified.

This letter conveys comments concerning issues that are germane to LACMTA's statutory responsibilities in relation to the proposed project as well as issues that may impact transportation operations on LACMTA owned facilities. It is noted that the proposed project would extend Lyons Avenue across an existing LACMTA-owned Railroad Right -of -Way (ROW). This ROW is operated and maintained by the Southern California Regional Rail Authority (SCRRA) and is used for the Metrolink commuter rail service and Union Pacific Railroad (UPRR) freight operations. The following concerns related to the project's proximity to the ROW should be addressed in the Environmental Impact Report (EIR): 1. The project sponsor is advised that SCRRA and the UPRR operate service in both directions and that trains may operate, in and out of revenue service, 24 hours a day, seven days a week. 2. The policy adopted by the SCRRA Board of Directors stipulates that if a new at - grade crossing is developed, two existing at -grade crossings in the area must be closed. 3. It should be noted that railroad crossings are under the jurisdiction of the California Public Utilities Commission (CPUC). The project sponsor will be required to obtain the necessary authorization to construct the crossing. This will include demonstrating that a grade separated crossing is not practical. 4. It is likely that this proposed crossing will include the addition of warning devices, traffic signal modifications, and railroad signaling modifications. These modifications, along with the necessary use of train horns will bring additional noise factors as a result of the project. All project development, engineering, and construction efforts must be coordinated with LACMTA Regional Rail, LACMTA Real Estate, and the SCRRA. 6. Any work performed on the project infrastructure or property requiring access to the railroad ROW, shall be covered by specific Right -of -Entry permits with specific requirements. These may include permits for construction of infrastructure, and any future repairs, painting, graffiti removal, etc., including the use of overhead cranes or any other equipment that could potentially impact railroad operations and safety. Frequent access for maintenance tasks such as graffiti removal, will necessitate an active license agreement. This agreement will include an annual license fee, and other requirements that meet safety standards for access to a ROW with active rail operations. 7. During construction, a protection barrier shall be constructed to prevent objects, material, or debris from falling onto the ROW. In addition, railroad flagging will be needed during construction to ensure the safety of passengers and train crews. 8. The project sponsor will be required to notify LACMTA of any changes to the construction/building plans that may or may not impact the ROW. 9. Improvements to existing facilities as part of the proposed project may result in an increase in foot traffic adjacent to the railroad ROW. To prevent trespassing along the active railroad ROW, the project sponsor may be required to install enhanced fencing to secure the ROW. Please note that the SCRRA may have additional comments concerning the operation and maintenance of the ROW which would come in the form of a separate correspondence from those parties. If you have any questions regarding this response, please contact me at 213-922-4313 or by email at SaponaraN@metro.net. Sincerely, Nick Saponara CEQA Review Manager, Countywide Planning cc.

As background information, SCRRA is a free -county JCinl Prrvrers Authority (JPA) that operates the regional commuter rail system known as Mctrolink. Additionally, SCRRA provides rail engineering, construction, operations and maintenance services to its five ,IPA member agencies. The JPA consists of the Los tangelos County Metropolitan 'transportation Authority (METRO), San Bernardino Associated Governments (SANBAG), Orange County Transportation Authority (OCTA), riverside County Transportation Commission (RCTQ and Ventura County Transportation Commission (VCTC). 'l'rc railroad right of way portion adjacent to the proposed project is operated and maintained by SCRRA. The proposed project is also located in the vicinity of Metrolink's Newhall Station at Market Street near Raitrvad Avenue. SCRRA is considered a "Re,"ponsihle Agency„ and should be included as such in any future EIR. Below is a list of general comments that are of concern for all proposed prujeUts near or adjacent to the railroad right of way. These are based on our initial cursory review of the NOP for the DEIR and its passible impact on the railroad. Please note that these are initial general comments submitted to meet the public comment period. SCRRA may follow up with more specific comments for consideration if further analysis deems it necessary. The t6lLowing concerns related to the projects proximity to the railroad right of way (�UW) should be addressed in the FIR. 1. Please be advised that MetrolinI uperates approximately 30 passenger trains and GPRR operates 6 height trains daily within this corridor. Trairrs operate 24 hours per day, seven days per week and are suhjet:t to change. IETROLI I , Southern Callornia Regional Rail Authority 2. City is advised that the SCRRA Board has adopted a policy on establishment on new at - grade crossings. Phis policy encourages all new crossings of the commutcr rail lines to be grade separated to eliminate the potential for future at -grade crossing accidents with vehicles and/or pedestrians. At -grade crossing options may he considered only in the event of drastic: risk reduction measures that would include closing two or more crossings in the vicinity and making other safety enhancements to the remaining crossings that would handle the additional traffic flaws across the rail tracks. 3. Any approval of an at -grade crossing option would have to be supported by SCRRA Member Agency (Metro), operating railroads, SCRRA and the C:alifamia Public- utilities Commission (UUC). 4, Now at -grave crossings would need to be equipped with many new automatic warning devit=, vehicular and pedestrian signals and gates. Federal Railroad requires that train hums be sounded when approaching these highway -rail grade crossings. Considerable noise would be created at the new grade crossing by the sounding -of the bells and train hams. S. [ether transportation related impm.ts to new at -grade crossings is the potential for exposure to wxidcltts involving trains, vehicles and pedestrians. Thcsc incidents create significant delays to all related modes of transportation. 6. All Engineering for project development within the railroad R/W must be coordinated with SCRRA and meet all SCIJR-A required standards for elmssiags and construction aver rail limes. Metrolink has adopted a new SCRRA Highway -Rail Grade Crossings Recommended Design Practices and Standards Mannair This docurnonted can be found on our websitc at %vwvv.raetruIinktrains.c_om. 7. The location of your new crossing of Lyons Avenue is proposed to be over the existing railroad tracks between the 13Th Street and Markct Street at -grace crossings. ncc new crossing location is in the immediate vicinity of the end of our control paint C:P Hood_ An at -grade crossing in the vicinity of these control signals and switch could be problematic in the design. Construction of this at -grade option could costs millions of dollars with having to reloeatc CP Hoard to avoid these conflicts and the actual costs of a new crossing which meets all current standards. Options to this crossing location include utilizing and improving 13* and/or Market Streets to Dockweller Drive and subsequently Plaue,rita Canyon Rd. to connect the Newhall cunuuunities. Other option is to grade separate the proposed Lyons Avenuc extension with an overpass that would span over the switch and control point location. 8. During construction of your project, City's contractor will be required to fallow SCPJZA Right of Way Encroachment Pmwdures, including obtaining a Right of Entry agreement (SCRRA Form 6) and have an SCRRA Employee in Charge (flagman) present to protect train operations. `hose requirements can also be found an our website at www.meirolinkir-ains.com.

NOP of an Environmental Impact Report (EIR) for the Lyons Avenue At - Grade Rail Crossing/Extension Dear Mr. Chow, Thark you for the Notice of Preparation of and EIR for the Lyons Avenue At - Grade Crossing Project. Over the past thre-e years, the Southern Califcmm Ragbnal Rail Authority (SCRRA) and the City have been working on this project. In May 2008, SCRRA submitted comments on the North Newhall Specific Plan EIR Notice of Preparation (NOP). Our recommendations and cornrnents relating to the Lyons Avenue at -grade crossing and other crossing improvemants have not changed. Although the focus of this project is the grade crossing only (Stage 1), the new Ei R should consider the future land uses and future traf€ic impacts as propused in the North Newhall Specific Plan. Consequently, a copy of SCFRRA's letter on the prior EIR NOP is attached as a restatement of our comments for the preparation of this new EIR. The SCRRA has recently updated the grade crossing standards and guidelines, which incorporate the most current industry standards for vehicular and pedestrian crossing treatments. A oapy of the new guideline is available for download at www+r.metrolinktrains_ cm. These standards replace the guidelines submitted in the May 20D8 comment letter. As the project moves forward, we request and expect to receive timely notice, in accordance with PublFc Resources Code Section 21002.5 and State CEGA Guideline Section 15088, of subsequent environmental documents relating to this project, and the time and place of any scheduled public meetings or public hearings by the agency decision makers at least 10 days prior to such a meeting. 1 700 a, Flower Street 26th Floor Los Angeles CA 90017 TO [2131 452.0200 Fax [2131 452.0461 www.rnetr hPktrains,tom €f yDu have any questicns regarding these comments please centart Elizabeth Mahoney, Government and Regulatory Affairs Manager at 213 452-0259 cr maheneyL,@scrra.net.

Subject: NOP of an Environmental Impact Report (EIR) for the Proposed North Newhall Specific; Plan (NNSP) Stage 1; Lyons Avenue At -Grade Cross i ng Dear Mr. Smisko, Thank you for the Notice of Preparation of and F-IR for the Lyons Avenue At-Grede Crossing Project. Over the past two years, the SCRRA and the City have been working 4n this project. In the ;nterest of improving railroad safety, the SCRRA continues to recommend that the crossing be grade separated, rather than at -grade. In that regard, the following comments are submitted as applicable to the CFQA EIR process. As you are aware, the SCRRA is a five -county Joint Powers Authority (JPA) that operates the regional commuter rail system known as Metrolink on member agency -owned and cn private freight railroad rights of way. Additionally, SCRRA provides a range of raid engineering, construction, operations and maintenance sarvims to its five JPA member agencies. The JPA member agencies are the Los Angeles County Metropolitan Transportation Authority (Metro) — previously referred to as MTA, t-he Orange! County Transportation Authority (CCTA), San Bernardino Associated Governments (SANBAG), the Riverside County Transportation Commission (RCTC) and the Ventura County Transportation Commission (VCTC), The railroad right of way in the project area is owned by Metro, not the Southern Pacific Railroad as noted in the Initial Study, SCRRA operates one commuter rail route, the Antelope Valley Line alorg this right of way. The proposed Lyons Avenue would crass the existing two tracks just south of railroad control point Hood (CP Hood). Based on the projact's impact to the rail line and Newhall station, the following recommendations concerning issues that are germane to our agency's statutory responsibilities in relation to the proposed project are being conveyed by SCRRA for inclusion in the LIR development: 200 S. Flower Street 25th Floor Los Angeles CA 40017 'Cot (2131 452.0200 Fax 1213) 452.0425 www.metraHnktrai n!:. roams N'NSF Lyons Ave. At grade Crossing Fagn 2 1. The SCRF A's Grade Crossing Resolution 9$-21 and Grade Grossing Design Guidelines outline all pertinent policies and procedures that wial he required by the City for considerabon of adding a new crossing, and copies are attached. The SCRRA's policy is to support the creation of a new rail -highway grade crossing only if #mprovements to other grade crossings, including the elimination of grade crossings are made part of the creation of the new crossing, which together clearly improve public convanience and safety. Therefore, the SORRA requests that as par# of the DEIR development, the City analyze and evaluate nDt only the closing of the 13'h Street crossing, as described in the NUP. but also: the closing of the Market Street at -grade Grossing to vehicular traffic (and the necessary redirected mess from Lyons to the station parking area); the closing of the Calex Grossing; corridor-wida crossing improvements at the Sanitatbri District private Grossing to the south; safety enhancemerts at Sarr Fernando Read (sidewa)k, signal preemption, pedestrian facilities), and Drayton Street safety erhancernents_ The SCRRA also requests that these improvements be made prior to or in conjunction with the apenFng of the Lyon Street cressing (if approved)_ 2. Please note that as part of our grade crossing policies, the City will also need approval from Metro to add a crossing on the Metro -owned ROW. Metro, as a SCRRA member agency, would make the request on the City's behalf to the SCRRA Board of Directors for support of the City's application to the PUG. 3. The NOP states that the implementation of the NNSR will be incorporated into the traffic analysis and will he discussed generally in this stage of the EiR. The traffic analysis in the Stage 1 EIR should evaluate the cumulative impacts of ail development in the project area inc)uding, but nct limited to, the Downtown Newhall plan, the Masters College Plan and the Ncrth Newhall 5peciliG Plan {NNSPj. 4. The traffic analysis should canaider the traffic circulation related to this proposed at -grade crossing at the extension of Lyons Avenue, particularly in light of the proximity of San Fernando Road. 5. The traffic circulation plan should also consider kinking the three major east side streets, Lyon, Via Princesse and Magic Mountain to provide similar parallel traffic flow as San Femando Road on the west side. It is our understanding that the City has prior plans for an overcrossing at Magic Mountain, which SCRRA would support in concept. 5. For train activity and vehicle dwell -time analysis in the project area, please use the following service characteristics: There are currently 24 weekday Metrolink trains and an average of 5 daily freight trains through this location; the SCRRA Strategic Assessment projects 32 weekday Matrclink trains by 2015 and 42 weekday Metrolink trains by 2020. Weekend service is projected to increase from 12 daily NNSP Lyons Ave. At Grade Grassing P32e � trains to 20 trains by 2020. Future freight trains volumes are expected to increase by at least 4 daily trains within a couple of years. 7. The crossing area would traverse two tracks and potentially impact the existing CP Hood. The City shall be responsible for the costs asscciated with any changes needed in the control point as a result of the crossing, if approved. 8. Existing or proposed traffic signals within close proximity of the railroad must be interconnected with the railroad signal controls. This will allow for proper preemption to allow vehirolar traffic to clear track area prior to arrival of trains. Close coordination with the City and railroad is critical to allow for safe movements of vehicles. 9. SCRRA, along with the CPUG. shall participate in the design and construction of the crossing and this work should be coordinated with our Engineering department. As the project moves forward, we request and expect to receive timely notice, in accordance with Public Resources Code Section 21092.5 and State CFQA Guideline Section 15088, of subsequent environmental documents relating to this project, and the time and place of any scheduled public meetings or public hearings by the agency decision makers at least 10 days prior tc such a meeting.

Santa Clarita, CA g 1355 Subject: NOP of an Environmental Impact Report (EIR) for the Proposers North Newhall Specific Plan (NNSP) Stagg 1: Lyons Avenue At -Grade Crossing Dear Mr. Smisko, Thank you for the Notice of Preparation of and EIR for the Lyons Avenue At -Grade Crossing Project. Over the past two years, the SCRRA and the City have been working on this project. In the interest of improving railroad safety, the SCRRA continues to recommend that the crossing be grade separated, rather than at -grade. In that regard, the following comments are submitted as applicable to the CEQA FIR process. As you are aware, the SCRRA is a five -county Joint Powers Authority (JPA) that operates the regional commuter rail systern known as Metrolink on member agency -owned and on private freight railroad rights of way_ Additionally, SCRRA provides a range of rail engineering, construction, operations and maintenance services to its five JPA member agencies. The JPA member agencies are the Los Angeles County Metropolitan Transportation Authority (Metro) — previously referred to as MTA, the Orange County Transportation Authority (CCTA)T San Bernardino Associated Governments (SANSAG), the Riverside County Transportation Commission (ROTC) and the Ventura County Transportation Commission (VCTC). The railroad right of way in the project area is owned by Metm, not the Southern Parlfio Railroad as noted in the Initial Study. SCRRA operates ❑ne commuter rail route, the Antelope Malley Line along this right cf way. The proposed Lyons Avenue would crass the existing two tracks just south of railroad control point Hood (CP Hood). Eased on the project's impact to the rail line and Newhall station, the following recommendations conceming issues that are germane to our agency's statutory responsibilities in relation to the proposed project are being conveyed by SCIRRA for inclusion in the EIR development: 700 5_ Flower Street 26th Flour Los Angeles CA 90017 Tel [213] 452.0200 Fax [213] 452_0429 w ww.metrol i» kt rai [is.co m NNSP Lyons Avr,_ At Grade Crossing Pape 2 1. The SCRRA's Grade Crossing Resolution 95-21 and Grade Crossing Design Guidelines outline all pertinent policies and procedures that will be required by the City for consideration of adding a new crossing, and copies are attached. The SCRRA's policy is to support the creation of a new rail -highway grade crossing only if improvements to other grade crossings, including the elimination of grade crossings are made part of the creation of the new crossing, which together clearly improve public convenience and safety. Therefore, the SCRRA requests that as part of the DE I R development, the City analyze and evaluate not only the closing of the 1 31h Street crossing, as described in the NQP, but also: the closing of the Market Street at -grade crossing to vehicular traffic (and the necessary redirected access from Lyons to the statiun parking area); the closing of the Calex crossing; corridor -wide crossing improvements at the Sanitation District private crossing to the south; safety enhancements at San Fernando Road (sidewalk, signal preemption, pedestrian facilities), and Drayton Street safety enhancements, The SCRRA also requests that these Emprovements be made prior to or in conjunction with the opening of the Lyon Street crossing (if approved). 2- Please note that as park of our grade crossing policies, the City will also noed approval from Metro to add a crossing on the Metrc-owned ROW. Metro, as a SGRF A member agency, would make the request on the City's behalf to the SCRRA Board of Directors for support of the City's application to the PUC. 3, The NQP states that the implementation cf the NNSP will be incorporated into the traffic analysis and will be discussed generally in this stage of the EiR. The traffic analysis in the Stage 1 EI R should evaluate the cumulative impacts of ad development �n the project area including, but not limited to, the Downtown Newhall plan, the Masters College Plan and the North Newhall Specific Plan (NNSP). 4. The traffic analysis should consider the traffic circulation related to this proposed at -grade crossing at the extension of Lyons Avenue, particularly in light of the proximity of San Fernando Road. S. The traffic circulation plan should also consider linking the three major east side streets, Lyon, Via Princessa and Magic Mountain to provide similar parallel traffic Cow as San Fernando Road on the west side. It is our understanding that the City has prior plans for an overcrossing at Magic Mountain, which SCRRA would support in cuncept. S. For train activity and vehicle dwell -time analysis in the project area, please use the following service characteristics: There are currently 24 weekday Metrolink trains and an average of 5 daily freight trains through this location; the SCRRA Strategic Assessment projects 32 weekday Metrolink trains by 2015 and 42 weekday Metroi nk trains by 2020. Weekend service is projected to increase from 12 daily NNSP Lyons Ave_ At GradrCirussulg Page 3 trains to 20 trains by 2020. Future freight trains volumes are expected to increase by at least 4 daily trains within a couple of years. 7. The crossing area would traverse two tracks and potentially impact the existing CP Flood. The City shall be responsible for the costs associated with any changes needed in the control point as a result of the crossing, if approved. 8. Existing or proposed traffic signals within close proximity of the railroad must be interconnected with the railroad signal controls, This will allow for proper preemption to allow vehicular traffic to clear track area prior to arrival of trains. Close coordination with the City and railroad is critical to allow for safe movements of vehicles. 9. SCRRA, along with the CPUG, shall participate iri the design and construction of the crossing and this work should be coordinated with our Engineering department. As the project moves forward, we request and expect to receive timely notice, in accordance with Public Resources Code Section 21092.5 and State GFQA Guideline Section 1,50U, of subsequent environmental documents relating to this project, and the time and place of any scheduled public meetings or public hearings by the agency decision makers at least 10 days prior to such a meeting.

Santa Clarita, CA91355 Delivered via email to: MHennawy@santa-clarita.com Re: Notice Of Preparation - Lyons Ave. Extension Project Dear Mr. Hennawy: Past road extensions, i.e., Via Princessa extension, received no review before the Planning Commission and no public scoping hearings. Although a community meeting was held recently for this project, it did not include a presentation of the City's proposal, nor did it provide a hearing opportunity for formal community input. Because of the impacts of this project on the community, impacts to Placerita Creek, and the railroad crossings, we urge the City to provide all opportunities to receive public input so that all concerns may be heard and addressed to help develop a project proposal that meets everyones' needs. Piece-mealing The California Environmental Quality Act (CEQA) requires that the whole project and its impacts be considered. It is not permissible under CEQA to divide a project into smaller pieces or sections to reduce project impacts that would occur if the whole project were considered. We assert that his project is being piece-mealed to reduce project impacts. The City fully intends to extend this road to Highway 14. We urge the City to include the impacts of the next phase of this road extension. Obviously it is not going to stop as indicated on the map, but is intended to be built to connect to Highway 14. The next phase will meet several obstacles including a roadway that is to close to existing houses, a steep grade, grading of a significant ridgeline and associated impacts to aesthetics, and the potential for requiring removal of many oaks. Some of these obstacles may make the extension impractical. If that is the case, these obstacles should be discussed now, rather than wasting money and time on a phase of a roadway that cannot be completed. Indeed, piece-mealing a project, as is proposed by this NOP, is contrary to CEQA guidelines and may open the project to a legal challenge. GHG Production - Wrong Baseline The NOP states that there will be no impact to Greenhouse gas production. CEQA requires that the impacts produced by a project be weighed against existing conditions. It is obvious that the NOP analysis has reached conclusions of less than significant impacts throughout the document by first using the wrong baseline. It is well known that in Save our Peninsula v. Monterey County Board of Supervisors (2001), 87 Cal.App.4rh 99, 125, the Court of Appeal stated: SCOPE Comments on the NOP for Lyons Ave. Extension 2 "Section 15125, subdivision (a), now provides: "An EIR must include a description of the physical environmental conditions in the vicinity of the project, as they exist at the time the notice of preparation is published, or if no notice of preparation is published, at the time environmental analysis is commenced.... This environmental setting will normally constitute the baseline physical conditions by which a lead agency determines whether an impact is significant. " (Italics added.) Furthermore, the section 15126.2 now provides as follows: "In assessing the impact of a proposed project on the environment, the lead agency should normally limit its examination to changes in the existing physical conditions in the affected area as they exist at the time the notice of preparation is published, or where no notice of preparation is published, at the time environmental analysis is commenced" These amendments reflect and clarify a central concept of CEQA, widely accepted by the courts, that the significance of a project's impacts cannot be measured unless the EIR first establishes the actual physical conditions on the property. (County of Amador v. El Dorado County Water District, supra, 76 Cal.App.4t' at p. 953, 91 Cal.Rptr.2d 66; Environmental Planning & Information Council v. County of Carmel -by —the-Sea v. Board of Supervisors, supra, 183 CalApp.3d 229, 227 Cal.Rptr. 899.) In other words, baseline determination is the first rather than the last step in the environmental review process." We urge the City to include GHG analysis in the DEIR that is weighed against the proper base line. Noise We concur with the NOP analysis that this project will create substantial levels of noise and vibration for the existing residential neighborhoods. We urge the City to include alternative and mitigation to reduce noise levels to existing residents. Air Quality Per our comments on GHG, it appears that the City may intend to use the wrong baseline for air quality and traffic analysis. The Santa Clarita Valley is in a non -attainment area for ozone, PM2.5 and PM10 air pollution. In a rating from marginal to extreme, the SCV was rated severe. Approval of the 2007 Air Quality Management Plan allowed local entities to request a "bump up" to the Extreme classification. This "bump -up" applies to ozone only. The category change allowed an extension of time to comply, but required instituting certain mitigation measures and the attainment of "milestones". We do not see the required mitigation measures in the DEIR. Nor is there a discussion of the milestones that must be reached in order to comply with the 2007 Air Quality Plan. Without compliance, Federal funding for road expansion will be denied. The health effects of this pollutant as described on the EPA air quality website are as follows: Ozone —"(a) Pulmonary function decrements and localized lung edema in humans and animals; (b) Risk to public health implied by alterations in pulmonary morphology and host defense in animals; (c) Increased mortality risk; (d) Risk to public health implied by altered connective tissue metabolism and altered pulmonary morphology in animals after long-term exposures and pulmonary function decrements in chronically exposed humans; (e)Vegetation damage; and (f) Property damage." SCOPE Comments on the NOP for Lyons Ave. Extension The attainment date for PM2.5 is much earlier then the 2024 extended date for the ozone extreme designation. The PM2.5 plan, due in 2008, is still being processed with the US EPA. Adverse health effects for particulate pollution as described by the EPA website are as follows: PM10 "(a) Exacerbation of symptoms in sensitive patients with respiratory or cardiovascular disease; (b) Declines in pulmonary function growth in children; and (c) Increased risk of premature death from heart or lung diseases in the elderly". PM2.5 Same as above. Based on the thresholds of significance identified in Appendix G of the 2005 CEQA Guidelines, a project would have a significant effect on the environment if it would: (a) conflict with or obstruct implementation of the applicable air quality plan; (b) violate any air quality standard or contribute substantially to an existing or projected air quality violation; (c) result in a cumulatively considerable net increase of any criteria pollutant for which the project region is non -attainment under an applicable federal or state ambient air quality standard (including releasing emissions which exceed quantitative thresholds for ozone precursors); The DEIR should address these issues. Wildlife corridors and impacts to Placerita Creek Placerita Creek is a tributary to the Santa Clara River which serves as a major wildlife corridor. The DEIR should thoroughly discuss these issues and provide alternatives that would reduce impacts to Placerita Creek and its function as a wild life corridor. An alternative should be provided that would enhance the function of this tributary by replanting with native riparian plants, thus enhancing the re -charge and corridor values of the tributary. At Grade Railroad Crossings The project proposes an at -grade railroad crossing immediately north of the existing Newhall MetroLink station. At grade crossings are permitted through the California Public Utilities Commission (CPUC). In the past, the CPUC has not granted approval for such crossings. This issue should be discussed in the DEIR. An alternative should be included that provides for a bridge going over the railroad crossing, in the event that such a crossing does not receive approval. The financial requirements for building a bridge should also be discussed in the DEIR. An at -grade crossing may slow or otherwise impede MetroLink trains on this railroad line, as well as adding to the potential for train/car accidents that already exists at several crossings. The DEIR should evaluate this increased risk. Also, a stalled train may impede emergency access to the Placerita Canyon neighborhood as has occurred in other areas of the Santa Clarita Valley. While the potential for such an impact already exists, it would be increased by the proposal at hand. Traffic and Circulation It appears that his project may impact access or create other traffic related problems for the Newhall Library as well as increasing traffic and noise on Lyons Ave. Please address these issues in the DEIR. SCOPE Comments on the NOP for Lyons Ave. Extension E Conclusion We believe that conducting the environmental analysis for this project at this time is premature, unless the City has the funding to begin work and complete the entire (not just this first phase). It appears that the project will have substantial major negative impacts on adjacent residents, reducing both their home values and their quality of life. It will increase cumulative air pollution and add to GHG production in the Santa Clarita Valley. We therefore urge the City to re -consider moving forward with this project at this time. At a minimum, the City should conduct noticed hearings on this NOP to hear from residents and consider the financial impacts of the project. We will be providing additional comments as the public process continues and request to receive a copy of the DEIR when it becomes available. Thank you for the opportunity to participate.

This project would substantially damage the community I live in, as well as create an unsafe crossing of the railroad tracks. Currently there are about 460 homes in Placerita Cyn, and a smattering of commercial business. Residents are able to use the south gated entrance whenever going in that direction with the use of a gate card, which many residents take advantage of, but we still use 13th street when going into Newhall. In spite of the decreased traffic due to the south access, residents must still often wait at the tracks for trains to clear the station and the crossing. The plan will increase the traffic using the crossing over the tracks by making it convenient to go down Lyons and use the proposed Dockweiller Extension. The increase in traffic would come from the revitalization of Newhall, additional proposed development in Placerita Canyon to the tune of over 750 new homes and a lot of commercial development, and the revitalization of Lyons Corridor. Additionally, there will be increased traffic from the development of the approved Disney Project and the approved Gates -King Project. Even if the crossing was expanded to 4 lanes (2 in each direction) it could not adequately handle the destined increase in traffic. It would increase the wait times for ingress and egress of Placerita Canyon residents. Another problem would be the additional impacts to the lifestyle of Placerita Canyon residents like myself. Taking Page 1 of2 down the bluffs that shelter the canyon, and actually define the canyon would open it up for noise and light pollution, from both trains and the city. Placerita Canyon is a low-key, rural equestrian community, where kids still ride their horses down to the Sidestore on hot days for a soda. Also negatively impacted would be the residents along Dockweiller, who depend upon the street as a place to park their cars, but more importantly, as a place to walk, as their are NO SIDEWALKS, and actually, no place to put them either. In some places the walls of homes are within feet of the street. The proposed crossing at Lyons would also be over the Newhall creek, creating the possibility of pollution of our local Newhall water, as well as a disruption to the flora and fauna that depend upon the creek. It would be adjacent to a large floodway area. Lastly, I do not see how Newhall Avenue could possibly be raised the 4 1/2 to 5 feet necessary for an at -grade crossing without seriously impacting the neightborhood and surrounding neighbors who use Newhall Avenue daily for their north -south commute. It would be endangering the community, as it would hinder the ability of residents to get out of the community, as we have seen when traffic has been diverted to Newhall Ave. in freeway emergencies. Please protect our community, and do not put in the Dockweiller extension, nor the Lyons crossing. Preferred by myself and my neighbors would be a safety upgrade of the 13th street crossing, without encouraging additional usage.

Here are three points I'd add to your draft checklist: i. I don't see reference to vertical or horizontal alternatives to this proposed railroad grade crossing at Lyons Avenue, which one would expect in a Draft EIR. In particular, it is the policy of Metrolink and the CPUC to discourage new railroad grade crossings in favor of grade separations, especially for such a major arterial as Lyons/Dockweiler: "Any new highway -rail grade crossings are strongly discouraged by not only the SCRRA but by the CPUC and FRA and other State and Federal Agencies." Page 3, SCRRA HIGHWAY —RAIL GRADE CROSSINGS, June 30, 2009. A further difficulty— and construction impact— of such a grade crossing is the significant elevation difference between Railroad Avenue and the adjacent railroad tracks that would have to be filled in. 2. I'd elaborate on the note under XVI. Transportation/Circulation, Response a-g, "The potential of the Project to cause a substantial change in traffic patterns in relation to existing traffic loads and capacity on local streets will be analyzed in the EIR." Cumulative impacts of revitalizing downtown Newhall, development of the new Gates King and Disney projects, and the projected over 75o new homes and commercial development in Placerita Canyon would likely turn quiet, narrow Dockweiller (currently with no sidewalks) into a major traffic corridor. 3. And in addition to the Response under I. Aesthetics, substantial bulldozing of hills that create the Newhall Creek canyon would potentially impact the larger Placerita Canyon community with increased noise and light.

We think it is an unnecessary expense for something that doesn't need fixing in the first place. We have lived in Placenta Canyon for over 40 years and have found the crossing at 13`h. Street to be more than adequate. The money to move the crossing could be much Metter spent finishing some of the other read projects going on around Santa Clarita. The extension of Dockweiler would benefit no one in our opinion except Lorene Weste in the sale of her property to build the road. Moving the roads would necessitate removing the storage units and maybe other businesses in that area. it would add more conjestion at Sierra Hwy as it does not lead onto the freeway and would hinder the already congested intersection of Sierra Hwy and Newhall Ave in trying to get to the freeway. I really don't see that it would be convenient for anybody to use that road. As for moving the crossing to Lyons Ave we feel that would only add more congestion and confusion in trying to get out of the canyon and would put the businesses out of business that are along the railroad tracks and Arch Street. That location would be too close to the metrolink station and would cause the gates to close every time a train is in the station adding more waiting to get out of the canyon even if the train is stopped at the station. If homes are ever built ( which would destroy the canyon ) they should be re- routed over to the Wiley Cyn bridge area and money better sent on putting the Via Princessa roars through to the freeway. Thera is only a short distance to span to complete that road and would serve many more people than Dockweiler would. It would be much less expensive and not necessary to move the railroad crossing. If the city has extra money they want to spend it would be much appreciated it it went to aid Some of our schools or other causes that would benefit the people of Santa Clarita. 1k � x .t • "� ��`.� � ��+.�� �,✓J�"fir? 1 LYONS AVENUE/DOCKWEILER DRIVE EXTENSION PROJECT SCOPING MEETING COMMENT FORM City of Santa Clarita August 21, 2013 Name: & Organization (if any): Address: 2kl � I , City, State, Zip: 4 Phone (optional): E-mail: (optional)r may Yes No Would you like to remain on our mailing list to receive future project updates?

Rendall and family and I have lived in the Placerita Canyon area of Santa Clarita for 32 years. I want to thank you for the opportunity to be heard to express my concerns about this subject. The question WHY is this issue on the City Santa Clarita master plan reoccurring? City staff states that this road development is needed to provide and improved traffic flow and emergency access to the Placerita canyon community. When the private road Placerita Canyon Rd. was closed at one end only by the Placerita Canyon Association. The through traffic was curtailed, when Placerita Canyon was gated at one end. This limited and reduced the number of crossings at the 13th street at grade rail crossing. If Dockweiler is s connected to Placerita Canyon Rd. traffic would double or triple at an at grade crossing, whether 13th street or Lyons avenue extend is the at grade crossing. The ideal solution would be a road crossing under or over the railroad tack and the elimination of one of the existing at grade crossing. Also develop Arch street east side of the railroad to and include Placerita Canyon, Dockweiler connection and Newhall Ave. south of the at grade crossing at Railroad avenue and Newhall avenue. The City of Santa Clarita City Planning must be asked the following questions: 1. What is the purpose of moving the existing crossing at 13' Street to a larger Lyons Ave crossing? Which would cause three at grade crossings within 3/8 of a mile. (Newhall / Railroad Ave., Market Street and the new purposed Lyons Ave.) 2. Where is traffic going to or from east of the purposed Lyons Ave new at grade crossing? 3. What is going to handle the traffic presently using the 13th Street at grade crossing? 4. Is Dockweiler going to connect to Lyons Ave. to provide an east/west route across the Santa Clarita Valley to Sierra Highway? 5. Is Wiley Canyon / Via Princessa bridged railroad over crossing to provide an east/west route across the Santa Clarita Valley to the 14 Fwy. and/or Sierra Highway? 6. Has the City of Santa Clarita studied the possibility of using the existing Market Street at grade crossing and extending the -connection to Dockweiler? (no additional R/R crossing needed) 7. How will the purposed future development impact the Lyons Ave. crossing and the removal of the I3th Street at grade crossing. The 13th Street at grade railroad crossing presently accommodates the vehicular traffic; of Placerita Canyon residents, 4 Churches, 1500 student most which don't drive daily and staff at Masters College and Town & Country preschool all, use 13th Street on a daily basis and is gated that restricts options to the traffic volume. If the 13th Street at grade crossing where eliminated and Lyons extension railroad crossing allowed. What will Dockweiler's, future development? Additional through traffic must be considered at peak traffic times, not the average rate as stated in the Stage I EIR. A tentative concept approval from the CPUC must be formed prior to presentation to the communiy-y with mediation measures. A full financial impact must be communicated to community on each of the purposed alternatives. In Conclusion: I believe it is unconscionable to install an at grade railroad crossing when other option are available. The manipulating of the EIR process by omitting the facts that are needed for the CPUC to measure the true impact. Also omitting the required information in Stage I EIR in order to minimizes the migration measures or sway a reasonable persons judgment is gross negligence on the part of the City of Santa Clarita and staff. If the PUC is given the full information in the (Stage I EIR) of an at grade railroad crossing with the knowledge of the increased vehicular traffic, and increased rail future usage of the tracts when they are being used for freight and metro link schedules, Bullet Train etc. Options to follow: 1. The CPUC would likely conclude that a new bridged over crossing at Lyons Ave, is in best interest of public safety. 2. The CPUC must deny the Lyons Ave request until the Stage II EIR is complete for review. 3. Or/ Deny the new Lyons Ave crossing to explore the utilization of the - existing Market -Street at grade railroad croSS with no impact to the Rail system, and connect to Dockweiler via Arch St, from the development east side transition road. 4. Leave the 13th Street at grade rail crossing as it is.

City staff and project consultants will be available at the scoping meeting to provide information on the project and the environmental review process. Comment cards will be provided for you to provide your written comments regarding the scope of the environmental areas to be analyzed. You may submit your written comments at the meeting or any time prior to the end of the comment period. PROJECT DESCRIPTION: The Lyons Avenue / Dockweiler Drive extension project is being coordinated by the City of Santa Clarita to implement the General Plan and to improve circulation and access to the Placerita Canyon and Newhall communities. The project includes the extension of Lyons Avenue from Railroad Avenue to the future connection with Dockweiler Drive at the Master's College site. The project will include reprofiling the intersection of Lyons Avenue and Railroad Avenue to allow the construction of a new SCRRA/UP railroad grade crossing east of Railroad Avenue. The new Lyons Avenue railroad grade crossing would improve traffic movements and safety at the railroad crossing. The City proposes the potential closure of and/or modification to the existing 13th Street railroad crossings, as part of this project. The proposed project will be approximately 0.40 :Hiles in length and would include a four -lane facility with a 12-foot raised landscaped median and a 13-foot parkway (8-foot sidewalk and 5-foot parkway) on each side. The travel lanes would be 11 feet wide with a five-foot bike lane. The typical right of way width will be 92 feet, consistent with the General Plan. ENVIRONMENTAL REVIEW: An Environmental Impact Report (EIR) will be prepared as part of the review of this project. A Notice of Preparation (NOP) of the EIR for the project has been distributed to responsible agencies and the review period for the NOP is from August 5, 2013 to September 3, 2013. On Wednesday, August 21, 2013, the City of Santa Clarita will be conducting a scoping meeting for public input on areas of interest to be analyzed within the EIR.

Placenta Canyon is a Rural Equestrian Community so designated as a Special Standards District in Santa Clarita's UDC TvpiG 3, Air guaMy • The area is already in non -attainment with federal and State clean air standards. Three additional elements: more trains, more traffic, and longer waits for each vehicle to make the crossing, will create more air pollution in an area already suffering. • Under the Global Warming Solutions Act of 2006 (AB 32) California emissions MUSt be reduuetl to 1,9g0 levels by 2020 The heavier volume of traffic combined with longer wait times will result in more emissions not less in an already non- attainnient area. Topic 4 Blologicai Resources • The at -grade crossing will adversely aftect Newhall Creek. a "blue line" stream that +s under Fish and Game turisdlction.

Under the most exigent of circurnstances, the gate was useless for evacuation and residents, many with horse trailers in tow had to bring the!r possessions and vehicles to cross at the railroad tracks Topic 8. Hydrology ■ New FEMA studies have been done: they show much of Placenta Canyon as well as mu& of the area affected by the proposed Lyons Ave. at -grade crossing and extension to Dockweller to be in a Floodway. The EIR will have to show how that designation impacts traffic flow and how roads must be designed to avoid the areas of concern. (Attached are the first 2 pages of an October 2012 letter from Santa Clarita which was sent to residents of Placerita Canyon.) The very recent FEMA letter to the City dated ALAgL!St 9. 2013 confirms the vulnerability of Placenta Canyon to flooding • I he engineering study commissioned by the City of Santa Clarita for the Backbone Sewer System In Placenta Canyon showed the system could be built WithOUt PUMPS Of lifts- glaVity Was Stlffl6ellt [0 chair PlaCefita Carryon plOpetlies from Sierra Highway to the field 0-e_ the former Casden property) where the connection could be rvadte to existing sewer lines along Railroad Ave- (foiri,,eiiy San Fernando Road) That 'Indicates all water tFOrn rains also drains to that field.

The project site does not contain known hazardous materials sites. Compliance with the California Environmental Quality Act (CEQA) must precede an application to the CPUC. In addition, this approval is sought prior to the completion of the North Newhall Specific Plan. The City has prepared an initial study for this activity and has found that the project may result in one or more significant effects on the environment; therefore, an environmental impact report (EIR) is being prepared. The City is seeking comments regarding the scope of the environmental document being prepared. Please submit comments, in writing, within 30 days of receipt of this notice, but no later than 5:00 p.m. on May 18, 2008. Comments may be submitted to Jason Smisko at the above address, or may be emailed to 1Sj IIS O Rysanta- clarita.com. A scoping meeting will be held for the project on April 28, 2008 at 6:00 p.m. in the City Council chambers. A copy of the NOP is available for review at the Planning Counter, and at the Los Angeles County Library, Valencia Branch. All references are available for review by request from Mr. Smisko. For this and other information, please contact Mr. Smisko at 661.255.4306.

North NewhallArea.................................................................................................................................................12 INTRODUCTION The City of Santa Clarita has prepared an application to the California Public Utilities Commission (CPUC) for approval of an at -grade roadway and pedestrian crossing of the Southern Pacific Railroad tracks within the city limits at the current eastern terminus of Lyons Avenue. The project consists of the detailed design and analysis of the Lyons Avenue at -grade crossing, lane configuration, signal timing, gate design, traffic analysis/traffic study, etc. in accordance with CPUC requirements. Approval of the at -grade crossing by the CPUC is a central component in the development of a Specific Plan for the North Newhall Specific Plan area, and for the implementation of the City General Plan Circulation Element, which specifies the extension of Lyons Avenue/Dockweiler Drive to the east. If the at -grade crossing is not approved, the General Plan Circulation Plan will need to be reconsidered and possibly amended, and the North Newhall Specific Plan will need to respond to a different circulation system. The City anticipates a number of significant impacts related to this project, and is therefore preparing an environmental impact report (EIR). The City will prepare a Staged EIR for the project. Project Description. The project for this first stage of the EIR is CPUC approval, and construction of, the at - grade crossing at Lyons Avenue. The second stage would consist of the extension of Lyons Avenue/Dockweiler Drive to Via Princessa and the development and implementation of a larger Specific Plan. Only the portions of the CPUC application relating to the crossing itself are considered in detail at this stage of the environmental review process. Other aspects of the project are considered to the extent they have bearing on the CPUC application process, and to the extent details are known. Accordingly, this stage of the EIR will not allow for approval of the Dockweilet Drive extension or approval of the Specific Plan with its associated development potential However, assumptions about the eventual extension of this roadway and the implementation of the Specific Plan will be incorporated into the traffic analysis and will be discussed generally in this stage of the EIR. The City action is limited to approval of an application to the CPUC for the following: Lyons Avenue at grade crossing 13th Street at -grade crossing abandonment, Assuming CPUC approval, Stage II of the EIR will provide a full analysis of the construction of the crossing as well as potential impacts associated with the extension of Lyons Avenue/Dockweiler Drive and impacts associated with the North Newhall Specific Plan. COMPLIANCE WITH CEQA The City of Santa Clarita (the City), as the lead agency, has entered into the environmental review process to assess potential impacts that could arise from the implementation of the proposed project. Through this documentation process, the City ensures that all possible environmental effects are fully disclosed in compliance with the California Environmental Quality Act (CEQA). The proposed Lyons Avenue Crossing requires the approval of the California Public Utilities Commission (CPUC). Whether or not this crossing can be relocated is central to the ultimate design and use of the area known as the North Newhall Specific Plan area. The project proponents are therefore seeking CPUC approval to locate the crossing at Lyons Avenue prior to going forward with a Specific Plan for North Newhall. Other than zoning potential outlined in the Development Code and land use potential based on the General Plan, it is not yet known what will occur at the North Newhall site. Based on these documents, the following could occur on site: Residential Development Commercial Development Dockweiler Extension Lyons Avenue at -grade crossing (connected with Dockweiler Extension) Ultimately, the Specific Plan may propose amendments to the General Plan and Development Code to allow different uses, a larger or smaller amount of development, and particular proposals regarding the Dockweiler Extension. All of these variables may affect the type and magnitude of impact which would be analyzed in the second stage EIR- As stated previously, whether or not the CPUC will approve the crossing has significant implications for the larger project area. Therefore, a Staged EIR is considered appropriate. This type of document is used when a project involves more than one component, the details of later components are not yet known, and an approval is required at least two years in advance of construction of the later components which affects only a portion of the project. The City of Santa Clarita will be the lead agency for the preparation of a Staged EIR for the North Newhall Specific Plan. CEQA Guidelines Section 15167 describes the use of a staged EIR as follows: (a) Where a large capital project will require a number of discretionary approvals from government agencies and one of the approvals will occur more than two years before construction will begin, a staged EIR may be prepared covering the entire project in a general form. The staged EIR shall evaluate the proposal in light of current and contemplated plans and produce an informed estimate of the environmental consequences of the entire project. The aspect of the project before the public agency for approval shall be discussed with a greater degree of specificity. The approval of the at -grade crossing followed by consideration of the roadway extension and Specific Plan are consistent with this description. The purpose of using a Staged EIR is to avoid unnecessary and premature analysis, and to focus the review on the aspects of the project necessary to present to the CPUC a grade crossing permit. As stated previously, the two components of the project (CPUC approval, followed by Specific Plan and roadway extension) are interdependent. The crossing change would not likely be done without the development of the North Newhall Specific Plan area, and vice a versa. Preparing two separate CEQA documents could be considered segmenting the analysis, which is not allowed. Stages of the EIR STAGE 1: This EIR will focus upon environmental effects of establishing an at -grade crossing at Lyons Avenue, pursuant to the City's General Plan and consistent with CPUC requirements. This EIR will assess the potential adverse environmental consequences associated with the detailed design of the crossing; lane configuration, signal timing, gate design, etc. such that the CPUC permit requirements are satisfied. Impacts associated with the various road extensions and specific plan development would be considered in a generalized programmatic approach, as set forth in the table below. Once the Stage 1 document is certified it will serve as the CEQA compliance document for the CPUC application process. Assuming approval by the CPUC, the City will prepare the Stage II document. STAGE 2: Detailed analysis of Dockweiler and Via Princessa extensions and a full analysis of the North Newhall Specific Plan development. Analysis of Specific Plan site biology, geotechnical, archaeology, etcetera will occur at this stage (the majority of the analytical detail). A subsequent Notice of Preparation will be circulated and the public will have additional opportunities to comment on the scope of the document, to participate in public hearings, and comment on the EIR. The following table will help the reader understand the project and the stages at which detailed environmental analysis will occur.

As described by Section 15063 of the CEQA Guidelines, an Initial Study can be used to: • Provide a preliminary analysis of potential project -specific and cumulative environmental effects of a proposed project; • Identify environmental issue areas where the proposed project may have the potential to result in significant impacts that should be evaluated in a project -specific EIR; • Enable the lead agency to modify a project to avoid or mitigate adverse impacts before an EIR is prepared, thereby allowing a Negative Declaration or a Mitigated Negative Declaration to be prepared for the project; and • Document the factual basis for the finding in a Negative Declaration or a Mitigated Negative Declaration that a project will not have a significant impact on the environment. The project will be the subject of an Environmental Impact Report; therefore, this document serves as notice to the public and interested agencies of the proposed scope of the document. City of Santa Clarita Community Development Department 23920 Valencia Boulevard, Suite 300 Santa Clarita, California 91355 Contact: Mr. Jason Smisko Senior Planner JSAOSKO@santa-clatita.com (661) 255-4306 Fax: (661) 259-8125 LEAD AGENCY LOCATION The project is located in the Newhall area of the City of Santa Clarita, east of the Santa Susana Mountains in northern Los Angeles County, California (refer to Figures 1 and 2). Santa Clarita lies east of the I-5 south of Castaic junction and the intersection with San Fernando Road, formerly known as Highway 126. Major landmarks in the area include Magic Mountain to the northwest, Interstate 5 to the west, and the Santa Clara River to the north. The project area is at the current terminus of Lyons Avenue at the Southern Pacific Railroad tracks in the community known as Newhall. The general area affected by the project is shown in Figure 3. BACKGROUND General Plan. The Santa Clarita General Plan was adopted in 1991 and has been amended over the intervening years. The Circulation Element for the City identifies the Lyons Avenue corridor as a major roadway, and programs for Dockweiler Drive to connect the city with Sierra Highway and Highway 14. In order to achieve this goal, the present terminus of Lyons Avenue at San Fernando Road must be removed and crossing must be installed. The City General Plan also designates the North Newhall Specific Plan area, east of the railroad tracks and north of Old Town Newhall (see Figure 3). The North Newhall Specific Plan area is to contain a mix of residential and non-residential uses. Zoning. In the immediate vicinity of the proposed crossing, land uses include Industrial Commercial and Special Purpose (railroad). As mentioned previously, the North Newhall area is designated a Specific Plan area, with a mix of residential and non-residential uses. OBJECTIVES The purpose of the project is to achieve CPUC approval of an at -grade crossing at the current terminus of Lyons Avenue and the Southern Pacific Railroad line. The project has the following objectives: • Develop and implement a Specific Plan for the North Newhall area as designated in the General Plan • Implementation of the goals of the Circulation Element of the Santa Clarita General Plan, including the crossing at Lyons Avenue and the eventual extension of Lyons Avenue/Dockweiler Drive • Provide a crossing meeting the standards of the CPUC • Provide sufficient information for CPUC application and approval of the proposed crossing APPROVALS Responsible agencies are defined in Section 15381 of the CEQA Guidelines as all public agencies other than the lead agency which have discretionary approval power over the project." Possible responsible agencies for the project or components of the project include: • California Public Utilities Commission • Metrolink/Southern California Regional Rail Authority • Army Corps of Engineers • California Department of Fish and Game • Los Angeles County Fire Department • Los Angeles County Public Works Department • Metropolitan Transportation Authority • Regional Water Quality Control Board • South Coast Air Quality Management District • U.S. Fish and Wildlife Service The roles of the responsible agencies vary according to their jurisdictional powers. Specific future approvals by agency include, but are not limited to: • City of Santa Clarita o Approval of an application to the CPUC for the at -grade crossing at Lyons Avenue, including certification of the Stage I EIR • CPUC o Approval of the application for the crossing, and certification of the Proponent's Environmental Assessment (the Stage I EIR) • City of Santa Clarita o City Council approval of North Newhall Specific Plan and certification of the Stage II EIR • Army Corps of Engineers (Section 404 IvWI' for future creek crossing) • California Department of Fish and Game (1601 Streambed Alteration Agreement for future creek crossing) • Regional Water Quality Control Board (NPDES for individual projects >1 acre, 401 Water Quality Certification for fixture creek crossing) Figure 1.

The evaluation of potential environmental impacts determined that the project would not result in environmental impacts or less than significant impacts in the issue areas that are listed below and that are denoted with a The project has the potential to result in significant environmental impacts in issue areas denoted with a "✓ ✓ Aesthetics ✓ Agriculture Resources ✓ Air Quality ✓ Biological Resources ✓ Cultural Resources ✓ Geology/Soils/Geotechnical ✓ Hazards & Hazardous Materials ✓ Hydrology/Water Quality ✓ Land Use/Planning * Mineral Resources ✓ Noise ✓ Population/Housing ✓ Public Services ✓ Recreation ✓ Transportation/Traffic ✓ Utilities/Service Systems ✓ Mandatory Findings of Significance * No impact or less than significant impact ✓ Significant or potentially significant impact CEQA GUIDANCE The State CEQA Guidelines were used in answering the checklist questions: 1. A brief explanation is required for all answers except "No Impact" answers that are adequately supported by the discussion. A "No Impact" answer is adequately supported if the discussion shows that the impact simply does not apply to projects like the one involved (e.g., the project falls outside a fault rupture zone). A "No Impact" answer should be explained when it is based on project -specific factors as well as general standards (e.g., the project will not expose sensitive receptors to pollutants, based on a project -specific screening analysis). 2. All answers must take account of the whole action involved, including offsite as well as onsite, cumulative as well as project -level, indirect as well as direct, and construction as well as operational impacts. 3. Once the lead agency has determined that a particular physical impact may occur, then the checklist answers must indicate whether the impact is potentially significant, less than significant with mitigation, or less than significant. "Potentially Significant Impact" is appropriate if there is substantial evidence that an effect may be significant. If there are one or more "Potentially Significant Impact" entries when the determination is made, an EIR is required. 4. "Negative Declaration: Less than Significant with Mitigation Incorporated" applies where the incorporation of mitigation measures has reduced an effect from "Potentially Significant Impact" to a "Less Than Significant Impact." The lead agency must describe the mitigation measures, and briefly explain how they reduce the effect to a less -than -significant level (mitigation measures from earlier analyses may be cross- referenced). 14 5. .Earlier analyses may be used where, pursuant to the tiering, program EIR, or other CEQA process, an effect has been adequately analyzed in an earlier EIR or negative declaration (State CEQA Guidelines Section 15063[c][D]). In this case, a brief discussion should identify the following. a). EarkerAnaysif Used. Identify and state where they are available for review. b). Impacts AdequateyAddressed. Identify which effects from the above checklist were within the scope of and adequately analyzed in an earlier document pursuant to applicable legal standards, and state whether such effects were addressed by mitigation measures based on the earlier analysis. c). Mitigation Measures. For effects that are "Less than Significant with Mitigation Measures Incorporated," describe the mitigation measures which were incorporated or refined from the earlier document and the extent to which they address site -specific conditions for the project. 6. Lead agencies are encouraged to incorporate into the checklist references to information sources for potential impacts (e.g., general plans, zoning ordinances). Reference to a previously prepared or outside document should, where appropriate, include a reference to the page or pages where the statement is substantiated. 7. Supporting Information Sources: A source list should be attached, and other sources used or individuals contacted should be cited in the discussion. S. This is only a suggested form, and lead agencies are free to use dififerent formats; however, lead agencies should normally address the questions from this checklist that are relevant to a project's environmental effects in whatever format is selected. 9. The explanation of each issue should identify: a) the significance criteria or threshold, if any, used to evaluate each question; and b) the mitigation measure identified, if any, to reduce the impact to less than significance Identification of the potential for residual significant adverse environmental impacts would trigger the need for preparation of an EIR. For, issue areas in which no significant adverse impact would result or impacts would be reduced to a less -than -significant level by mitigation, further analysis is not required. 15 Less Than Potentiall Significant y with Less Than Significan Mitigation Significan No Issues t Impact Incorporated t Impact Impact a. Have a substantial adverse effect on a scenic vista? X c. Substantially degrade the existing visual character or quality X of the site and its surroundings? Setting Scenic Vistas Scenic vistas are publicly accessible viewpoints that provide views of areas that exemplify a community's environment (ie., scenic resources). The Santa Clarita General Plan identifies the Angeles National Forest and the Los Padres National Forest as major scenic resources in the area, as well as woodlands extending into area canyons, and waterways such as the Santa Clara River, Placerita Canyon and Newhall Creek. The General Plan states that these resources represent "the feeling of development placed within a country or rural area." These resources are visible from numerous locations throughout the city, including I-5, Main Street and Soledad Canyon Road. Scenic Quality and Character The analysis of visual impacts is not an exact science. There have been few comprehensive programs designed to incorporate visualization tools into modeling systems, or evaluate the usefulness and applicability of such systems. Quantitative analysis is therefore difficult at best. As a result, visual quality is often rated on a relative qualitative scale, which places high value on expansive, prominent features, variation in topography and items of visual interest such as rock outcroppings or peaks. High value visual environments in urban areas include those that impart a strong sense of unity and proportion, as well as unique or interesting design features. Impacts to scenic quality and character are assessed from publicly accessible viewpoints; there are no state or federal designated scenic routes in the planning area. Locally, views from major roadways such as I-5 and Main Street are considered important. Within the project area, views from Main Street and passing trains are considered of primary importance. As mentioned previously views from the project area are both urban and rural in nature. In the project area, the visual quality of the environment is diminished by the lack of uniformity in terms of both type and design of existing structures, and the presence of relatively denuded natural areas. The overall scenic quality and character is considered common to low. 16 Light and Glare Sources of light in the planning area include streetlights, and exterior lighting. The project area and city are largely lit, with the exception of undeveloped portions of Newhall Creek. Glare is light reflected off of reflective surfaces, including expanses of glass, and certain siding and paving materials, as well as metal roofing. Significance Criteria State CEQA Guidelines consider an impact significant if the project will have "a substantial, demonstrable negative aesthetic effect." Impacts are generally considered significant if the proposed project would substantially block an existing view from a scenic corridor or if the character of an area were impaired. Impacts are also considered potentially significant if substantial light and glare would be generated by the project, or if residents would be subject to substantial light or glare. Discussion of Checklist Answers a-b. Scenic features visible from the project area include Placerita Canyon and the Newhall Creek corridor. The EIR will evaluate impacts to important aesthetic features in the area from the at -grade crossing, in detail, and from the North Newhall Specific Plan and roadway connections, in general. C. As discussed above, the existing quality and character of the visual environment within the planning area is diminished and obscured to a large degree by the form of existing development and the degraded quality of the natural environment. However, the EIR will evaluate, in detail, the impact of the crossing on the quality and character of the environment, and will discuss, in general, the impacts of the North Newhall Specific Plan and roadway connections. d. The EIR will evaluate the potential for light and glare from the proposed crossing, and will address, in general, the impacts of the North Newhall Specific Plan and roadway connections. Conclusion The EIR will address impacts related to scenic vistas, scenic features, aesthetic quality and character, and added light and glare_ Potentially Potentiall Significant y with Less Than Signifiican Mitigation Significan No Issues t Impact Incorporated t Impact Impact a.

The EIR will evaluate whether the implementation of the project would lead to conversion of farmland to non-agricultural use. Conclusion The EIR will evaluate the project area potential to support farmland, and will address whether the project will lead to further conversion of farmland. The area is not zoned for agricultural use and is not subject to a Williamson Act contract; therefore, these topics will not be addressed further in the EIR.

Setting The planning area is located within the South Coast Air Basin and is subject to the regulation of the South Coast Air Quality Management District (SCAQMD). The planning area is in non -attainment for both the federal and state standards for ozone, carbon monoxide, and nitrogen dioxide, and the state standard for PM10. The air quality monitoring station for the Santa Clarita Valley is located in Newhall; the historical reading for the various pollutants is included in the following table: Pollutant 1999 2000 2001 2002 2003 2004 Ozone, ppm — Maximum Concentration 1-Hour 0.12 0.13 0.18 0.17 0.19 0.16 Number of days state standard exceeded >0.09 m 18 36 49 81 89 69 Number of days federal standard exceeded >0.12 m 0 1 9 32 35 13 Carbon Monoxide, ppm — Maximum Concentration - 8 Hour 3.6 4.8 3.14 1.9 1.7 3.7 Number of days state standard exceeded >20.0/9.0 m 0/0 0/0 0/0 0/0 0/0 0/0 Number of days federal standard exceeded >35.0/9.0 m 0/0 0/0 0/0 0/0 0/0 0/0 Nitrogen Dioxide, ppm — Maximum Concentration — 1-Hour 0.099 0.096 0.10 0.10 0.12 0.09 Number of days state standard exceeded >025 m 0 0 0 0 0 0 Particulate Matter, <10 microns, µg/m3 — Maximum Concentration - 24 Hours 75 55 62 61 72 54 Number of samples exceeding state threshold >50 µ /m3 12 2 4 7 10 2 Number of samples exceeding federal threshold (> 150 µ /m3 0 0 0 0 0 0 Annual Geometric Mean State Standard = 30 /m3 34.5 29.0 28.5 32.5 NA NA Annual Arithmetic Mean(Federal Standard = 50 /m3 38.3 31.2 32.0 33.3 31.8 28.1 Source: Ly,&nx.a md. ov stro " Alr ua11t b,,Ye-r.htm accessed 4/2/08 Ozone is of particular concern in the valley. Review of SCAQMD data shows that the Santa Clarita Valley has some of the highest ozone readings in the air basin. This is due in large part to transport of pollutants from the 19 Los Angeles Basin. In general, ozone levels are in decline throughout California, due mainly to reductions in automobile emissions due to engine alterations. Discussion of Checklist Answers a. The applicable Clean Air Plan for the project is the SCAQMD 2003 Air Quality Management Plan. Consistency with the CAP is determined through answering the following questions: Is the project consistent with the population projections contained in the CAP? Does the project increase the rate of travel or VMT in a manner inconsistent with the CAP? Does the project include TCMs and other measures contained in the CAP? The EIR will contain a detailed evaluation of the crossing's consistency with the CAP, and will address consistency of the North Newhall Specific Plan and roadway connections in general. b-d. The EIR will contain a detailed evaluation of the crossing's potential to violate standards, including through project -specific and cumulative increases in pollutants, and the project's potential to impact sensitive receptors, including pollutant buildup at intersections. The EIR air quality analysis will include general assumptions about the North Newhall Specific Plan and roadway connections. e. Objectionable odors can include livestock, waste, or industrial emissions. The project will not be a source of such odors. This issue will not be addressed further in the EIR. Conclusion The EIR will address consistency of the project with the applicable CAP, and the potential for the project to generate pollutants. The EIR will not address the issue of odors further. Less Than Significant Potentially with Less Than Significant Mitigation Significant No Issues Impact Incorporated Impact Impact a. Have a substantial adverse effect, either directly or X through habitat modifications, on any species identified as a candidate, sensitive, or special status species in local or regional plans, policies, or regulations, or by the California Department of Fish and Game or U.S. Fish and Wildlife Service? 20 Less Than Significant Potentially with Less Than Significant Mitigation Significant No Issues Impact Incorporated Impact Impact c. Have a substantial adverse effect on federally X protected wetlands as defined by Section 404 of the Clean Water Act (including, but not limited to, marsh, vernal pool, coastal, etc.) through direct removal, filling, hydrological interruption, or other means? e. Conflict with any local policies or ordinances X protecting biological resources, such as a tree preservation policy or ordinance? Setting Newhall Creek and its environs represent the major natural feature in the project vicinity. Newhall Creek has been somewhat disturbed. Upper story or canopy vegetation is limited, and the creek banks and channel show evidence of erosion. An informal equestrian crossing currently exists in the vicinity of the intersection of Market Street and Race Street, and pedestrians from The Master's College also use the crossing to connect from a trail to the downtown area. Because it is somewhat disturbed, the potential for sensitive plants and animals is diminished. However, sensitive plants and/or animals may persist, including the San Fernando Valley spineflower (Chon.Zanthe panyi var. fernaniina), Slender -horned spineflower (Dodecahema leptoceras), Davidon's bush mallow (Malacothamnus damdsonu), Spreading navarretia (Navametia fossahs), Coastal western whiptail (Cnemidophoms tigm multiscutatus), and Two -striped garter snake (Thamnophis hammon&i). Raptors and other various sensitive birds may forage along the creek channel. Similar habitat and species mix can be expected in relatively undeveloped areas in and surrounding the North Newhall Specific Plan area and the areas affected by roadway connections. Discussion a. The project may impact sensitive species, particularly during construction activities. The EIR will address potential impacts to sensitive species in the short and long-term. b. The project may result in direct and indirect impacts to Newhall Creek. The EIR will address short and long-term impacts of the project on Newhall Creek. C. Newhall Creek may provide wetland functions. The EIR will address whether the project will impact wetlands during both the construction and operational phases_ 21 d. The Newhall Creek corridor and surrounding natural areas may provide wildlife movement opportunities. The EIR will address whether the project will create impediments to wildlife movement through direct means (introduction of structures) or indirect means (presence of nuisances such as light and population). C. The EIR will evaluate whether the project conflicts with any applicable policies and ordinances protecting biological resources. There are no Habitat Conservation Plans or Natural Community Conservation Plans that apply to the project area. This issue will not be addressed further in the EIR. Conclusion Impacts related to sensitive species, wetlands and riparian areas, wildlife corridors, and policies and ordinance protecting biological resources, will be addressed further in the EIR. The EIR will not contain further discussion of Habitat Conservation Plans or Natural Community Conservation Plans.

A records search was completed for the Downtown Newhall Specific Plan EIR which included the project site. No resources were identified in the search. Historical Resources. The Downtown Newhall Specific Plan EIR identified several historic buildings and features in the Old Town Newhall area, which may be affected by the project. 22 Discussion a. The EIR will evaluate whether the proposed crossing, North Newhall Specific Plan, or roadway connections will impact known historic resources in the area. b. Based on work completed for the Downtown Newhall Specific Plan EIR, there are no known archaeological resources on the project site. However, resources may be discovered during construction of any of the project components. The EIR will evaluate the potential for impact to archaeological resources during construction. C. No known paleontological resources are located within the planning area. However, paleontological resources may be discovered during construction of project components. The EIR will evaluate the potential for impact to paleontological resources during construction. d. Based on work completed for the Downtown Newhall Specific Plan EIR, there are no known cemeteries or other human burials located in the planning area. However, construction activity may disturb previously unknown burials_ The EIR will evaluate the potential for discovery of burials, and outline procedures to follow in case of discovery. Conclusion Impacts associated with historic, archaeological, and paleontological resources, as well as burials, will be addressed further in the EIR.

Have soils incapable of adequately supporting the X use of septic tanks or alternative wastewater disposal systems where sewers are not available for the disposal of wastewater? Setting The Safety Element of the General Plan provides general information about the geology and seismicity of the project area. Seismicity. Santa Clarita is located in a seismically active portion of California with numerous earthquakes in recent history. The nearest fault is the San Gabriel Fault, located northeast of the project area. Other faults in the vicinity include the Holser and Santa Susana. The most likely significant event in the area could occur along the San Andreas Fault, located 16 miles northeast of the City. None of the faults are mapped through the project area. Geology. The project area is underlain primarily by alluvium, which is found throughout the canyon bottoms and river areas of the City. Alluvium is silt deposited by creeks and rivers. The major hazard associated with alluvium is liquefaction. Alluvium tends to be unconsolidated, meaning there is space between the "grains" of soil. If alluvium is sufficiently saturated, and an earthquake occurs, the soil can take on more liquid characteristics, damaging structures. Discussion of Checklist Answers ai. Rupture is primarily of concern where a project site overlies or is immediately adjacent to a known fault. No known faults are located within the project area_ This issue will not be addressed further in the EIR. aii. The entire valley is at risk of damage from strong seismic groundshaking. As mentioned above, a number of active faults cross or are near to the City. An earthquake of sufficiently high magnitude along any of the faults could damage structures or lead to loss of life within the City. The EIR will evaluate the potential for groundshaking to affect the proposed crossing in detail, and the North Newhall Specific Plan and roadway connection development, in general. aiii. The EIR will evaluate the project's potential for risks related to liquefaction. aiv. The EIR will evaluate the project's potential for risks related to landslide. 24 b. The EIR will evaluate the project's risk of exposure to, or generation of, erosion. C. The EIR will evaluate the project's risks related to unstable soils. d.

Impair implementation of or physically interfere X with an adopted emergency response plan or emergency evacuation plan? Setting Hazardous Materials. The transport and clean-up of hazardous materials in the community is subject to regulation by a number of agencies, including Caltrans, and the Los Angeles County Fire Department. Risks associated with hazardous materials in the vicinity of the project site include the following: Area Roadways. According to the City's Safety Element, roadways in the vicinity of the planning area pose the highest risk of release of hazardous materials. Roadways such as San Fernando Road, the Antelope Valley Freeway (14) and the I-5 are approved for use by trucks carrying hazardous materials_ Accidents involving such trucks, especially along San Fernando Road could release hazardous substances that would affect the project site. Bail lines. Union Pacific Railroad transports hazardous materials through the community. Risk of accident and upset conditions exist along these lines, and would affect the project site. Industrial facilities. Industrial facilities around the project site pose risk of hazardous materials release. Automobile service operations in the planning area could release oil, lubricants, and other materials into the environment, for example, and manufacturing plants outside of the planning area have historically contaminated groundwater supplies and soils through improper operation. I Taturalgas lines. A number of natural gas transmission lines traverse areas near the project site. Rupture of these lines due to construction activity or seismic activity would release natural gas into the immediate area. Known Hazardous Alatenals Sites. There are no documented hazardous materials sites located within the planning area. Wildland Fire. According to the City's GIS Maps available at h!W:/Lwww.santa- clarit t com /cityhallladtnin /technology/gis,/ roducts5.asti, the project site is within an identified high fire hazard area. Discussion of Checklist Answers a-b. The EIR will evaluate the project's potential to impact the routine use, transport, and storage of hazardous materials, and will address the project's potential to result in upset or accident conditions. In particular, the EIR will evaluate the potential for the crossing and roadway connections to affect transport and accident potential for truck and freight rail traffic, and will address generation and use of hazardous materials at the North Newhall Specific Plan area in general terms. The project will not affect locations for disposal of hazardous materials; therefore, this topic will not be addressed further in the EIR. C. The planning area is within '/a -mile of William S. Hart High School, located on Newhall Avenue. The EIR will address the potential for use, transport, and accidents to affect the school. 26 d. Based on a review of the state Cortese List (accessed 4/08), there are no known hazardous materials sites located within the project area. e-f. The project area is not located within and airport land use plan area nor is it proximate to a public or private airport. g. The project -will alter circulation routes and may therefore affect both emergency access and evacuation routes_ The EIR will address the project's impacts on both. h. The project is located near wildland areas at risk of severe fire events. The EIR will address the project's risk of damage or loss of life from fires, and will address access for fire protection personnel and equipment. Conclusion The EIR will address potentially significant impacts related to the routine use, transport or storage of hazardous materials, impacts to schools, impacts to emergency access and evacuation routes, and risks related to wildfire. The EIR will not address issues related to disposal of hazardous materials, sites on the Cortese List, or impacts related to airport safety.

Expose people or structures to a significant risk of X loss, injury or death involving flooding, including flooding as a result of the failure of a levee or dam? Setting Groundwater Supplies. The project area is served by the Newhall County Water District (NCWD). NCWD obtains its water from groundwater sources in the Santa Clarita Valley and from the State Water Project via the Castaic Lake Water Agency (CLWA). Drainage and Runoff. The project area is relatively undeveloped. Runoff sheet flows from the North Newhall area and runoff along Lyons Avenue is captured in existing City storm drains which terminate in the Santa Clara River, located north of the project area. Flooding. Areas generally east of San Fernando Road are located within the 100-year flood zone of Newhall Creek. The extent of the 100 to 500-year flood zone follows Newhall Avenue to Lyons :avenue. Tsunami, Seiche, Mudflow. The project area is too distant from both the ocean and major waterbodies for tsunami or seiches to pose a risk. Significant landslides in the hills surrounding the project area could result in some debris reaching low-lying areas. 28 Discussion of Checklist Answers a. The EIR will address impacts related to water quality standards, particularly the contribution of new paved surfaces and construction activities to pollutants in stormwater flows. b. The proposed crossing will not impact groundwater supplies through additional water demand. However, implementation of the North Newhall Specific Plan, to the extent it will increase demand for water, may adversely affect groundwater supplies, and additional development in the area may decrease recharge potential. The EIR will address, in general, the impact of the project on groundwater supplies. c-f. The EIR will evaluate the potential for both construction and operation of the crossing, implementation of the North Newhall Specific Plan, and construction and operation of other roadway connections to disturb the drainage pattern of the area, and the potentially for erosion, siltation or flooding. g-i. Portions of the project area are within the 100-year flood hazard zone associated with Newhall Creek. The EIR will evaluate risks association with flooding for the crossing, and will address, in general, impacts related to development of the North Newhall Specific Plan and the roadway connections. The planning area is not located in an area at risk of tsunami or seiche: Therefore, these risks will not be addressed further in the EIR. The EIR will evaluate the potential for mud —flow to impact the project area, and whether the project will increase risk of mudflow in the area. Conclusion The EIR -will address impacts related to hydrology and water, except for impacts related to tsunami and seiche. Less Than Significant Potentially With Less Than Significant Mitigation Significant No Issues Impact Incorporated Impact Impact a. Physically divide an established community? X c. Conflict with any applicable habitat conservation X plan or natural community conservation plan? 29 Discussion a. The EIR will evaluate whether the project would physically divide established communities through road design impediments or other means. b. The EIR will evaluate whether the project is consistent with all applicable land use plans and regulations of agencies with jurisdiction over the project, including the Santa Clarita General Plan and Development Code, and the CPUC regulations for at -grade crossings. C. There are no habitat conservation plans or natural community conservation plans applicable to the project area. This issue will not be addressed further in the EIR. Conclusion Impacts relating to division of communities and consistency will plans and regulations are considered potentially significant and will be addressed in the EIR. Impacts related to habitat conservation plans and natural community conservation plans will not be addressed further in the EIR. Less than Significant Potentially With Less Than.

There are mineral resources through the City, particularly gravel and aggregate materials, and oil resources. Mineral resource extraction operations are neither active nor possible in the project area given the existing level of development surrounding and within the project area. This issue will not be addressed further in the EIR- Conclusions Impacts related to mineral resources will not be addressed further in the EIR. 30 Less Than Significant Potentially With Less Than Significant Mitigation Significant No Issues Impact Incorporated Impact Impact a. Exposure of persons to or generation of noise X levels in excess of standards established in the local general plan or noise ordinance, or applicable standards of other agencies? c. A substantial permanent increase in ambient noise X levels in the project vicinity above levels existing without the project? e. For a project located within an airport land use X plan or, where such a plan has not been adopted, within two miles of a public airport or public use airport, would the project expose people residing or working in the project area to excessive noise levels? Setting Noise Sources. The dominant noise sources affecting the planning area are vehicle traffic along major roadways such as Lyons Avenue, and San Fernando Road (plain Street). Rail operations along the Metrolink line are also a source of noise in the area. Secondary noise sources include existing industrial and automobile -related service operations. Existing Noise Levels and Issues. According to the Technical Background Report prepared for the Valleywide Plan (February 2004), noise levels at the Metrolink station are just over 65 decibels, with occasional spikes over 70 decibels. Within the project area, noise levels along San Fernando Road (Main Street) range between 52 and 63 decibels. Vibration. The major source of potential vibration in the project area is the rail line. 31 Discussion of Checklist Answers a. The proposed crossing will alter the flow of traffic in the area and the noise related to traffic. Additional persons could be exposed to noise as a result. The implementation of the North Newhall Specific Plan would introduce additional population in the area, and would further alter traffic volumes, flow and attendance noise. The EIR will evaluate noise based on information provided by the traffic study. b. The major source of vibration in the area is the rail line. The proposed crossing would not affect operations on the rail line, such as number or frequency of trains, such that vibration levels would be altered. The implementation of the North Newhall Specific Plan may expose additional persons to vibration. The EIR will evaluate vibration. c-d. As stated in (a) above, the proposed crossing, Specific Plan, and roadway connections would alter traffic patterns in the area and noise related to traffic_ The EIR will evaluate both temporary and long-term sources of noise. e-£ The planning area is not located within the vicinity of a public or private airport. This issue will not be addressed further in the EIR. Conclusion Impacts are considered potentially significant and will be addressed further in the EIR, with the exception of impacts related to public and private airports. Less Than Significant Potentially With Less Than Significant Mitigation Significant No Issues Impact Incorporated Impact Impact a. Induce substantial population growth in an area, X either directly (for example, by proposing new homes and businesses) or indirectly (for example, through extension of roads or other infrastructure)? c. Displace substantial numbers of people, X necessitating the construction of replacement housing elsewhere? Discussion of Checklist Answers a. The proposed crossing would alter the manner in which populations access the east side of Newhall Creek. The implementation of the North Newhall Specific Plan would directly induce growth through new homes and businesses, and the roadway connections would indirectly induce growth through the extension of infrastructure. The EIR will address these effects, with particular emphasis on the crossing 32 impacts. Impacts related to the North Newhall Specific Plan and roadway connections will be addressed in more general terms. b-c. The EIR will evaluate the impacts of the crossing, North Newhall Specific Plan, and roadway connections on existing housing and populations. Conclusion Impacts to population and housing will be addressed further in the EIR. Less Than Significant Potentially With Less -Than - Significant Mitigation Significant No Issues Impact Incorporated Impact Impact a. Would the project result in substantial adverse physical impacts associated with the provision of new or physically altered governmental facilities, need for new or physically altered governmental facilities, the construction of which could cause significant environmental impacts, in order to maintain acceptable service ratios, response times or other performance objectives for any of the public services: ii. Police protectio& x iv Parks? F:7 Setting Fire. The planning area is served by the Los Angeles County Fire Department. The nearest fire station to the project area is located at 24875 North San Fernando Road between 14t'� and 15th Streets. Police. The Los Angeles County Sheriff's Department handles crime prevention and response within the planning area and the city. The main sheriff s office is located north of the project area in Valencia.. The sheriff's department maintains a storefront in Newhall, which is typically operated between 8 and 10 hours per day and is sometimes staffed by civilians. Schools. Schools serving the planning area include the Newhall Elementary School District and the William S. Hart High School District. Most of the schools within the districts are over capacity. The Newhall Elementary School District has recently completed a number of construction projects aimed at relieving the overcrowding. Parks. The City of Santa Clarita provides and maintains a number of park facilities, totaling over 200 acres. The William S. Hart Park, located south of the planning area, is operated by Los Angeles County Parks and 33 Recreation, and totals over 364 acres. The Newhall Community Park is the nearest City -owned park to the planning area, totaling over 14 acres. The City also offers a trail system, in some places connecting to the Pacific Crest Trail. The City is currently aiming for 4 acres of parkland per 1,000 residents. The City is currently deficient in local parkland_ Libraries. The Newhall Library comprises over 4,800 square feet of facility space. All libraries in the city are operated by the County of Los Angeles. Current facilities appear to be undersized for the population served. Discussion of Checklist Answers ai-v. The proposed crossing will not generate new population which will increase demand for public services. However, the new crossing would alter routes and access for public safety services, such as fire and police. Implementation of the North Newhall Specific Plan would increase population demanding services. Future roadway connections would further alter access for public safety services. The EIR will evaluate impacts related to access vis a vis the crossing, and will address, in general, impacts to services related to Specific Plan implementation and roadway connections. Conclusion Impacts related to public services will be addressed further in the EIR. Less Than Significant Potentially With Less Than Significant Mitigation Significant No Issues Impact Incorporated Impact Impact a. Would the project increase the use of existing X neighborhood and regional parks or other recreational facilities such that substantial physical deterioration of the facility would occur or be accelerated? Setting Existing recreational facilities are described in the Public Services section. Discussion of Checklist Answers a-b. The proposed crossing will not impact existing neighborhood or regional parks, or other recreational facilities, since none presently existing in the vicinity of the crossing. However, the population generated by the North Newhall Specific Plan may increase use of existing recreational facilities, and deterioration of existing facilities or construction of new facilities may be required. The EIR will address these issues in general terms. 34 Conclusion Impacts to recreational facilities will be addressed in the EIR in general terms. Less Than Significant Potentially With Less Than Significant Mitigation Significant No Issues Impact Incorporated Impact Impact a.

Result in inadequate emergency access? X ........................... . g. Conflict with adopted policies, plans, or programs X supporting alternative transportation (e.g., bus turnouts, bicycle racks)? Setting Major roadways serving the project area include I-5, San Fernando Road (Main Street), Newhall Avenue, Lyons .avenue, Railroad Avenue, and the antelope Valley Freeway (14). The nearest public airport is located in Burbank, approximately 15 miles from Santa Clarita. The Jan Heidt Metrolink Station 0.25 miles south of the proposed crossing provides access to the regional rail system and commuter service. Discussion of Checklist Answers a-b. The proposed project would alter the circulation pattern in the area by: • Closing the existing at -grade crossing at 131" Street • Introducing a new crossing at the current terminus of Lyons Avenue 35 The CPUC requires traffic analysis for proposals of new at -grade crossings. The CPUC seeks evidence that the introduction of an at -grade crossing will not cause significant deficiencies in the operation of roadways such that motorists would be tempted to engage in unsafe crossings of the tracks. Therefore, the Stage I EIR will include a detailed traffic analysis. The traffic analysis will assume completion of the General Plan circulation network, including the extension of Lyons Avenue/Dockweiler to Via Ptincessa. Impacts will be analyzed in detail in the EIR. c. The project site is not located near a private or public airport. This topic will not be considered further in the EIR. d-e. The EIR will analyze impacts associated with potential hazards at the crossing. As mentioned previously, the CPUC is primarily concerned with safety at at -grade crossings. The EIR analysis will provide detail regarding hazards affecting motorists, trains, and pedestrians in the area. The EIR analysis will also address emergency access via the crossing. £ The proposed relocation of the crossing does not affect existing parking areas and would not include the development of parking. However, the North Newhall Specific Plan will include parking and development of roadway connections may impact existing parking areas. Impacts to parking will be addressed in general terms in the EIR. g. The EIR will address impacts to alternative transportation, including rail, bicycle, and bus traffic in the area resulting from the crossing, and, in general terms, those impacts resulting from the implementation of the North Newhall Specific Plan and roadway connections. Conclusion Impacts related to traffic operations will be addressed in detail in the EIR. Because there are no public or private airports in the area affected by the project, impacts related to airports will not be considered further in the EIR. Less Than Significant Potentially With Less Than Significant Mitigation Significant No Issues Impact Incorporated Impact Impact a.

Result in a determination by the wastewater Y, treatment provider which serves or may serve the project that it has adequate capacity to serve the project's projected demand in addition to the provider's existing commitments? g. Comply with federal, state, and local statutes and X regulations related to solid waste? Setting Wastewater. Los Angeles County Sanitation District No. 26 provides wastewater conveyance, treatment, and disposal for the project area. The Valencia Water Reclamation Plant is the treatment/reclamation plant serving the project area. Stormwater. The Santa Clarita Valley contains many natural streams and creeks that function as storm drain channels. These streams and creeks empty into the Santa Clara River, which flows westerly into the Pacific Ocean. The drainage system (both natural and County/City storm drain infrastructure) is adequate to handle the normal precipitation in the region (15 to 19 inches per year). However, abnormal rainfall amounts, as in the case of the 100-year flood event, can strain the system. The General Plan calls for localized channel repairs; cleaning of debris basins; cleaning, widening, and/or lining segments of channels; post -construction BW maintenance; and culvert maintenance, among other measures to address ongoing deficiencies. Potable Water. Water in the project area comes from a variety of sources. Imported water and groundwater are the primary sources of potable (drinkable) water in the Citv. Recycled water also contributes to the water supply. Newhall County Water District serves the Newhall area NCWD provides both local groundwater and Castaic Lake Water Agency (CLWA)-imported water. Landfills/Solid Waste. The Santa Clarita Valley is served primarily by three Class III (nonhazardous) landfills, Chiquita Canyon Landfill, Antelope Valley Landfill, and Sunshine Canyon Landfill. The city exports a majority of its wastes to the Chiquita Canyon Landfill. The city provides a variety of waste management services and waste reduction programs. 37 Discussion of Checklist Answers a. The proposed crossing will not generate wastewater. However, implementation of the North Newhall Specific Plan will increase generation of wastewater. Analysis in the Stage I EIR will include general information about wastewater generation, including impacts to treatment systems, associated with the North Newhall Specific Plan. b. The Stage I EIR will evaluate the impact of the crossing on existing water distribution and wastewater collection infrastructure. The EIR analysis will include general information about impacts to infrastructure related to the North Newhall Specific Plan and roadway connections. C. The analysis in the EIR will address temporary and long-term impacts to storrnwater infrastructure related to the crossing, and will provide a general assessment of impacts to stormwater infrastructure stemming from implementation of the North Newhall Specific Plan and the installation of roadway connections. d. The proposed crossing will not be a source of water demand in the long-term. The analysis in the EIR will evaluate in general terms the impacts to water supply from implementation of the North Newhall Specific Plan. e. The proposed crossing will not generate wastewater on an ongoing basis. However, implementation of the North Newhall Specific Plan will increase wastewater generation over existing conditions. The EIR will analyze, in general terms, the impacts to wastewater resulting from the Plan implementation. f-g. The proposed crossing will not be a source of solid waste in the long term. Short-term, construction activities will generate waste. Development under the North Newhall Specific Plan will be a source of solid waste long term. The EIR will analyze short and long-term sources of waste (the latter in more general terms) and compliance with applicable statutes. Conclusion Impacts to utilities will be addressed further in the EIR. 38 Less Than Significant Potentially With Less Than Significant Mitigation Significant No Issues Impact Incorporated Impact Impact a. Does the project have the potential to degrade X the quality of the environment, substantially reduce the habitat of a fish or wildlife species, cause a fish or wildlife species population to drop below self-sustaining levels, threaten to eliminate a plant or animal community, reduce the number or restrict the range of a rare or endangered plant or animal or eliminate important examples of the major periods of Ca 1+ ornia history or prehistory? c. Does the project have environmental effects X which will cause substantial adverse effects on human beings, either directly or indirectly? Conclusion The project may have significant impacts related to degradation of environmental quality, cumulatively significant impacts, or impacts to human beings as described elsewhere in this Initial Study. 39 DETERMINATION Pursuant to Sections 15152 and 15168 of the State CEQA Guidelines, this initial study has been prepared to evaluate the potential impacts of the proposed project. On the basis of this initial evaluation: I find that the proposed project COULD NOT have a significant effect on the environment, and a NEGATIVE DECLARATION will be prepared. I find that although the proposed project could have a significant effect on the environment, there will not be a significant effect in this case because of the mitigation measures described in the initial study. A NEGATIVE DECLARATION will be prepared. X I find that the proposed project MAY have a significant effect on the environment, and an ENVIRONMENTAL IMPACT REPORT is required. I find that the proposed project MAY have a significant effect(s) on the environment, but at least one effect 1) has been adequately analyzed in an earlier document pursuant to applicable legal standards, and 2) has been addressed by mitigation measures based on the earlier analysis as described on attached sheets, if the effect is a "potentially significant impact" or "potentially significant unless mitigated." An ENVIRONMENTAL IMPACT REPORT is required, but it must analyze only the effects that remain to be addressed. I find that although the proposed project could have a significant effect on the environment, there WILL NOT be a significant effect in this case because all potentially significant effects (a) have been analyzed adequately in an earlier EIR pursuant to applicable standards and (b) have been avoided or mitigated pursuant to that earlier EIR, including revisions or mitigation measures that are imposed upon the proposed project.

Marengo Avenue Third Floor Pasadena, CA 91101 Subject: Lyons Avenue At -Grade Railroad Crossing Stage I Draft EIR Santa Clarita, CA Dear Mr. Silverstein: I have reviewed the Lyons Avenue At -Grade Railroad Crossing Stage I Draft EIR, dated March 2010. 1 concentrated on the traffic and transportation issues, but I also reviewed the remainder of the text for background purposes. Following are my comments. 1. The document reports on the analysis of the first stage of a two -stage project that, in its second stage, entails the extension of an arterial street and the development of 213 acres of vacant land. As such, the analysis is incomplete, because the potentially significant impacts of the second stage of the project are ignored. The Draft EIR (DEIR) is focused on the analyses of the impacts of relocating the existing railroad crossing east of Railroad Avenue from its current location at 13t' Street to a new location as the extension of Lyons Avenue. However, one of the primary objectives of the relocation is to "Provide greater connectivity between Downtown Newhall, Placenta Canyon, The Master's College, and the residents that live along Dockweiler Driven [page 7.0-2] Fulfilling that "connectivity" objective will result in significant impacts on the North Newhall area by opening the area to the opportunity for substantial new development, on Dockweiler Drive because of increased traffic flow through the residential sections of the street, and on Lyons Avenue because of increased attraction as a route between the eastern and western parts of Santa Clarita and the two freeways that serve the city. The DEIR recognizes that by saying "... the two components of the project (CPUC approval [of the new railroad crossing], followed by Specific Plan and roadway [Dockweiler Drive] extension) are interdependent. The crossing change cannot be done without the development of the NNSP [North Newhall Specific Plan] area." [page 2.0-3] Yet, the effects of one part of the project upon the other and upon the greater environment must be postponed according to the DEIR. "The City will prepare the Stage II document upon receipt of a project application form deemed completed by the Community Development Department." [page 2.0-3] That statement is made even though enough is known about the NNSP that it can be described in great detail as to the proposed uses — residential units, research and development, offices, community retail, and a hotel — and as to the exact numbers of units and the exact floor areas of the non-residential components. [page 5.6-5] Telephone 5105 Cimarron Lane FAX (310) 558-0808 Culver City, CA 90230 (310) 558-1829 Mr. Robert P. Silverstein, Esq. May 26, 2010 Page 2 Certainly, that is enough detail that the specific impacts of that development and of the extension of Dockweiler Drive could be considered as part of a DEIR of the entire "interdependent" project. Postponing consideration of the difficult issues that will arise from the Stage II components may lead the reader to infer that the project proponent is avoiding addressing potentially significant problems for the developer of the NNSP. The fact that the probable developer of the NNSP is funding the preparation of the EIR can only strengthen that inference. [City Council action on May 26, 2009, authorizing the professional services agreement to prepare the EIR. "EIR preparation costs will be borne by the co -applicant, Casden Santa Clarita, LLC", according to the City Council Agenda Report. The City of Santa Clarita is the other co -applicant of the project.] 2. As currently configured, the Lyons Avenue railroad crossing will not connect to any existing street east of the railroad in "Stage 1" of the project. Therefore, the crossing will not be functional until a street connection — purportedly, the extension of Dockweiler Drive — is completed, and the analysis of the railroad crossing should not be separated from the analysis of the street extension, as they are "interdependent". State and federal agencies that are evaluating a road project apply the standard of "independent utility". That is, they determine whether or not the proposed road improvement will function on its own without further construction of another road project. As illustrated in several DEIR figures, the eastern extent of the Lyons Avenue railroad crossing project will be the western edge of Newhall Creek. [Figures 2.0-4, 5.5-5, and 5.6-1 ] The new crossing cannot function until it is connected to the rest of the street network. As currently proposed by the City, the extension of Dockweiler Drive is the connection. The "two components of the project ... are interdependent. The crossing change cannot be done without the development of the NNSP area." [page 2.0-3] As stated in the DEIR, the existing 13th Street railroad crossing is not proposed to be closed to traffic until Dockweiler Drive has been extended to connect to the new Lyons Avenue railroad crossing. "Upon approval by the California Public Utilities Commission (CPUC) and the completion of the future extension of Dockweiler Drive as a part of the North Newhall Specific Plan (NNSP) Stage 11 EIR, the existing 13th Street at -grade rail crossing would be abandoned." [page 3.0-4] Also, "Upon completion of the future Dockweiler Drive extension and the at -grade rail crossing at Lyons Avenue, the existing 13th Street at -grade rail crossing would be closed." [page 5.6-22] The Southern California Regional Rail Authority (SCRRA), a five -county joint powers authority created by the CPUC, has passed Resolution 98-21, which requires that a member agency that is requesting a new highway -railroad crossing also request the closure of an existing highway -railroad crossing, "so there will be no net increase in the number of highway -railroad crossings on SCRRA's commuter rail system." [page 5.6-17] Therefore, the Lyons Avenue crossing could not be opened until the 13th Street crossing can be closed. In the meanwhile, the Lyons Avenue crossing will have to be made unusable by the installation of barricades or similar methods to block traffic flow. Mr. Robert P. Silverstein, Esq. May 26, 2010 Page 3 There is no substantive explanation of why the proponents of the project are in a hung to produce the DEIR for the Lyons Avenue railroad crossing when its functionality is entirely dependent on the connection to Dockweiler Drive, and the EIR process for the extension of that street has not yet begun. When will the street extension be constructed, so the new crossing could be opened to traffic? 3. There is no indication in the DEIR that the extension of Dockweiler Drive will be feasible despite several severe physical impediments and substantial impacts on the environment along the existing street. Currently, Dockweiler Drive extends from a tee -intersection with Sierra Highway, near the southeastern limits of the City of Santa Clarita, to a short distance west of Leonard Tree Lane, a total length of approximately 9/10ths of a mile. Beyond the end of the paved roadway west of Leonard Tree Lane, the extension of Dockweiler Drive is an unpaved, narrow dirt track, less than two lanes wide, along a narrow piece of land that juts out toward the west from the existing residential neighborhood. On either side of the dirt road and at its western end, there are steep embankments to the valleys below. Both the side embankments and the valley to the west appear to be several hundred feet in height. The area on top of the land that is currently occupied by the narrow dirt road is not wide enough to accommodate the proposed street extension. Therefore, there will have to be substantial importing of earth and, perhaps, construction of large retaining walls to fill in the existing side embankments and provide an adequate "platform" upon which to build the new street. Extending the road toward the west across the valley may require further earth fill and retaining walls, or, perhaps, an expensive bridge with no connections to the land and developments on either side. Alternatively, Dockweiler Drive could be extended downward into the valley by way of relatively steep roadway grades and side slopes. Either method of extending the street will require substantial earth -moving that may make it impracticable to build the extension. "According to the Santa Clarita General Plan, Dockweiler Drive is designated as a secondary highway." [page 2.0-19] "The approved Master's College Master Plan amended the Circulation Element to define and re -designate Dockweiler Drive as a four lane secondary highway." [page 10.0-2] Currently, "Dockweiler Drive consists of one lane in each direction with a landscaped median and is used as the primary access to single-family and multiple -family residences along Dockweiler Drive." [page 2.0-19] Essentially, the existing street is acting as a Local Residential Street with parking permitted at all times at both curbs. The parking is used extensively throughout the day. The two roadways (including the parking) are each 25 feet wide, and the landscaped median that separates the roadways is 13 to 14 feet wide. Connecting that residential neighborhood street to a secondary highway will change the character of the street and the residential neighborhood that it serves. The proposed Dockweiler Drive -Lyons Avenue -Pico Canyon Road artery will provide a continuous east - west through route from substantially west of the Golden State Freeway (1-5) to the Antelope Valley Freeway (SR-14), an uninterrupted length of more than five miles. Obviously, such a Mr. Robert P. Silverstein, Esq. May 26, 2010 Page 4 route connecting several of the City of Santa Clarita's communities and the two freeways will attract substantial volumes of through traffic. The existing section of Dockweiler Drive functions as a residential neighborhood street now, because the only development it serves is residential, and there can be no through traffic from other communities, because the street ends at Leonard Tree Lane. Residents who are used to a relatively peaceful street environment will experience increased noise, vibrations, and potential safety hazards resulting from the intrusion of through traffic when Dockweiler Drive is connected to Lyons Avenue. There is no assurance that the existing street section, with only one traffic lane in each direction, will accommodate the substantial increases in traffic flows throughout the day, and particularly during the peak commuter periods. There may come a time when it will become necessary to eliminate the on -street parking on Dockweiler Drive in order to provide a second lane in each direction to match the four -lane divided configuration of the proposed secondary highway that will be built as the street extension toward the west to connect to Lyons Avenue. That elimination of curbside parking will cause a hardship to the residents along the existing section of the street who are used to the availability of on -street parking along Dockweiler Drive through their neighborhood, particularly those who have garages that will accommodate cars but not trucks. Is the City contemplating widening the existing segment of Dockweiler Drive to provide two lanes in each direction while retaining the parking? Adequate widening would essentially eliminate the landscaping, including mature trees, in front of many of the residences that line the street. Will sidewalks be provided along existing Dockweiler Drive to accommodate the school children and other pedestrians where there are no sidewalks now? Considering the increases in traffic volumes and vehicle speeds that will accompany the continuity of the street, the pedestrian safety issues must be addressed before connection can be approved. The City has recognized the potential for through traffic problems on Dockweiler Drive after its extension to Lyons Avenue. "[T]he City plans to incorporate traffic calming measures on Dockweiler Drive to limit cut -through traffic to and from Sierra Highway to maintain the residential character of the existing Dockweiler Drive." [page 5.6-6] This is an admission that the proposed connection of the two streets is a flawed plan that will immediately lead to significant impacts on the environment in the existing residential neighborhood. In traffic engineering, it is not typical practice to apply traffic calming measures to any arterial street, such as the secondary highway. For any arterial street, the primary purpose is the safe and efficient movement of traffic. The installation of traffic calming devices, with the sole purpose of slowing and making the street unattractive to through traffic flow, is at cross purposes with the secondary highway designation. Either the street will be a secondary highway accommodating substantial traffic flows or it will remain a residential neighborhood street providing access and parking for the homes adjacent to the street and a safe, attractive environment for the residents. The street cannot perform both functions effectively. If Dockweiler Drive is not to become a through traffic route, why not build the new section of the street to be discontinuous from the existing residential section? That is, start the new section in the valley near The Master's College and west of the neighborhood, and then Mr. Robert P. Silverstein, Esq. May 26, 2010 Page 5 extend it westward to the Lyons Avenue railroad crossing. That new section would serve the college traffic and provide connectivity to downtown Newhall for the NNSP development, which is one of the goals of the crossing project, while protecting the existing residential neighborhood. A discontinuity between existing Dockweiler Drive and the proposed secondary highway extension would have several advantages: 1) it would protect the existing residential neighborhood from through traffic; 2) it could be built without the substantial earth -moving costs and environmental impacts that will result from a connection to the existing Dockweiler Drive; and 3) the extension could be named Lyons Avenue to remove driver confusion that would result from a change of street names for the new section east of the railroad. There would be one disadvantage to the street discontinuity: drivers traveling from and to the NNSP development and other nearby developments could not use the extension as an access route to/from Sierra Highway and the Antelope Freeway. That would be a large component of the undesirable through traffic in the residential neighborhood that would not materialize if the discontinuous design is implemented. 4. One of the stated primary objectives of the Lyons Avenue railroad crossing is the improvement of traffic safety. But, the 13t' Street crossing has been relatively safe, and its safety could be further enhanced with modernized traffic control devices. Every traffic accident is regrettable, especially those that could have been prevented by a better physical condition or better application and operation of traffic control devices. "A review of the United States Department of Transportation (U. S. DOT) — Federal Railroad Administration traffic report indicates a total of four train -auto accidents have been recorded at the 13t" Street at -grade rail crossing since December 1977, including 1 fatality." [page 5.6- 9] The DEIR includes the actual accident reports for each of the four accidents as part of the appendix to the Overland Traffic Consultants, Inc. report, which itself is an appendix to the DEIR. Following are data for the four accidents. Date & Time of Accident 12/0311977; 5:35 p.m. 12/06/1990; 10:00 a.m. 01/16/1999; 3:30 p.m 07/2311999; 2:32 p.m Highway Vehicle Driver Action Stalled on crossing Stopped on crossing "Drove through gates" Stalled on crossing Number of Number of People Killed People Iniured 0 0 0 0 1 0 (83-year-old driver) 0 0 After the first accident in 1977, it was 13 years until the next accident in 1990. Then, it was more than eight years until the next two accidents, both in 1999. Since the fourth accident (July 1999), there have been more than ten years with no railroad crossing accidents at 13t" Street. That current record is better than the experience cited in the DEIR as exemplary for "the crossing at Ruether Avenue where only one accident has been reported in more than 10 years of operation." [page 5.6-29] Mr. Robert P. Silverstein, Esq. May 26, 2010 Page 6 In three of the four accidents, there was no one killed or injured in either the highway vehicle or on the train. In the one fatal accident, there was probably driver error, as the vehicle was driven through or around the crossing gates that were operating properly. Those four accidents over a 32-year period are not sufficient to warrant the relocation of the 13t' Street railroad crossing to Lyons Avenue for safety considerations. All four accidents could have been prevented by the installation of better traffic control devices, that is, the same devices that are being proposed in the DEIR for the relocated crossing and are described as "Sealed corridor safety enhancements". [page 5.6-29] The proposed measures for the Lyons Avenue crossing include "four -quadrant gates to eliminate all travel across the tracks when the signals are activated, ... raised central medians, ... and video cameras to monitor operation of the at -grade rail crossing ..." [pages 5.6-29, 30] If those or similar measures had been installed at the 1 e Street crossing, all four accidents, especially the fatality, would likely have been prevented. It would be interesting and useful to the public and the decision makers to have a comparison between the experience of four railroad -highway vehicle accidents in 32 years (1977 through 2009) at the existing 13t' Street railroad crossing versus the highway vehicle accident history at the nearby Lyons Avenue/Railroad Avenue intersection during the same 32 years. Although we do not have the accident history for the street intersection, the City staff has access to it, and they should be requested to provide the street intersection accident history for comparison purposes. 5. The DEIR conclusion that the proposed railroad crossing relocation project will not be "growth inducing" is contradicted by other statements in the DEIR. According to the DEIR, "Generally, a project may foster spatial, economic, or population growth in a geographic area if it meets any one of four criteria that are identified below: • Removal of an impediment to growth (... the provision of new access to an area) ..." [page 10.0-1 ] Also in the DEIR, "Growth in an area may result from the removal of physical impediments or restrictions to growth. In this context, physical growth impediments may include non- existent or inadequate access to an area or the lack of essential services." [page 10.0-2] The DEIR discussion in Section 10 continues by describing several amendments to the General Plan Circulation Element that called for the extension of Dockweiler Drive, as a four -lane secondary highway, and its connection to Lyons Avenue. The objective of that street project would be "... to allow for traffic flow from Sierra Highway to Interstate (1) 5 Freeway." [page 10.0-2] Then, the DEIR authors come to the following conclusion: "This project [relocation of the railroad crossing] is not growth inducing as the proposed project would facilitate circulation within an infill area of the City and does not encourage growth into the area. As such, the proposed project would not be considered growth inducing." [page 10.0-2] That conclusion Mr. Robert P. Silverstein, Esq. May 26, 2010 Page 7 seems to be based on the theory that a street that is shown in the Circulation Element, although not actually built, can be considered as if it actually exists and is usable by traffic. The conclusion is completely contradicted by a statement in the "Alternatives" section of the DEIR. In describing "Alternative 1 — No Project Alternative", the DEIR states, "The Stage 11 North Newhall Specific Plan (NNSP) would not occur" if the railroad crossing relocation does not take place. [page 7.0-10] The NNSP is the planned development of "809 dwelling units plus a commercial land use component of approximately 176,500 square feet (sf) of research and development uses, 186,500 sf of office uses, 40,000 sf of community retail, and a hotel of 70,000 sf." [page 5.6-5] Therefore, a substantial and, perhaps, the primary purpose of the railroad crossing relocation (Stage 1) project is to facilitate the development planned for the NNSP (the Stage II project). Contrary to the DEIR conclusion, it should be concluded that any street improvement project that will make it feasible to build such an extensive development should be considered growth inducing, and the relocation of the railroad crossing meets that definition. 6. The stoppage of trains at the nearby Metrolink station may impact traffic flow at the proposed Lyons Avenue railroad crossing. "The nearest rail station to the proposed project is located at Railroad Avenue and Market Street approximately 0.2 mile south of the Lyons Avenue and Railroad Avenue intersection (project site)." [page 3.0-7] The station is approximately 1,000 feet south of the proposed railroad crossing. Will trains stopped at the station result in the crossing gates and flashers remaining activated for the duration of the stop? If so, the crossing would not be usable for highway vehicle traffic during those stops, which will be most significant during the morning and afternoon commuter traffic and commuter train peak periods. If it can be documented, with technical information about the operation of the crossing gates and signals, that there will be no interference with Lyons Avenue traffic flow as a result of stopped trains and the operation of the crossing protection devices, that should be presented clearly in the DEIR. In either case, the concern that has been expressed by many Santa Clarita residents should be specifically addressed in the DEIR. 7. The analysis of the construction impacts of the project does not address the most important issue — the detouring of traffic from Railroad Avenue and Lyons Avenue while both streets are being elevated and widened. The railroad track east of the Lyons Avenue/Railroad Avenue intersection is approximately 4'/ to 5 feet higher than the existing surface of the street intersection. To achieve an at - grade crossing of the railroad, substantial sections of both streets will have to be elevated — Lyons Avenue from Main Street to Railroad Avenue, and Railroad Avenue from approximately 9t' Street to north of 11#h Street. In conjunction with the elevation of the two streets, both streets will be widened, and new sidewalks, retaining walls, and improvements to the adjacent properties will have to built. During the time that the two streets are being re -constructed, traffic that currently uses those streets will have to be detoured to other streets. For example, Lyons Avenue traffic heading to the existing 1 e Street railroad crossing may be forced to use Walnut Street and 12t' Mr. Robert P. Silverstein, Esq. May 26, 2010 Street to bypass the construction area. North -south traffic currently using Railroad Avenue may have to use Main Street, Walnut Street, or Newhall Avenue. The DEIR does not address the significant issue of traffic that will have to be detoured during the substantial street re -construction period. [page 5.6-221 The only construction - related issues addressed are the movements of large construction equipment and the commuting of construction workers, both of which are significant issues, but will be far less disrupting than the closure of two arterial streets to all traffic during the re -construction of both streets. The construction -related questions that should be addressed by the DER include the following. 1) Will the streets that are available for detour routing have the capacities to carry the substantial volumes of additional traffic? 2) What will be the impacts on developments, particularly downtown businesses, adjacent to those streets? 3) How far from the construction area will drivers route themselves to the detour streets in order to minimize congestion and delay near the construction area? 4) What will be the impact of construction detouring and related congestion on access to and use of the Metrolink station that is located only two blocks south of the beginning of the Railroad Avenue re -construction section? 8. The requirements of the construction plan mitigation measure are confusing and contradictory. Mitigation Measure MM 5.6-1 begins with the requirement that "The applicant shall develop and implement a construction traffic control plan (CTCP) prior to the start of construction." [page 5.6-26] Some of the conditions for the plan are as follows: • "The CTCP shall be submitted to, and approved by, the City Engineer." [emphasis added] • "In areas where traffic control necessitates, the contractor shall provide, post and maintain 'No Parking' and `No Stopping' signs, as directed by the Director of Public Works." [emphasis added] • "The locations of all signs shall be determined in the field by the County Engineer in conjunction with the contractor." [emphasis added] Are those requirements meant to apply to three different people? Or, are the City Engineer and the Director of Public Works the same person? And, why is the County Engineer involved in performing a single task during a construction project that is entirely within the City of Santa Clarita? In summary, my recommendation is that further study be given to the feasibility of connecting Lyons Avenue to Dockweiler Drive and to the practical problems and environmental impacts that will result. As part of that study, there should be serious consideration of my recommendation to extend Lyons Avenue to the vicinity of the Master's College but not connect it to the existing residential section of Dockweiler Drive, as discussed on pages 4 and 5 of this letter. Mr. Robert P. Silverstein, Esq. May 26, 2010 Page 9 Then, after an agreeable program has been set forth, a single DEIR should be prepared to analyze the impacts of the relocation of the railroad crossing, the extension of the arterial street, and the extensive development proposed for the NNSP area, particularly the Casden project and the Compass Blueprint Project. At that time, sufficient duration should be provided for the public to review the complex, multi -faceted project that is the total of all of the issues that should be considered as an "interdependent" project. I would be pleased to discuss my comments with you, with members of the public, and with the staff and officials of the City of Santa Clarita. Very truly yours, Arthur L. Kassan, P.E.

The City of Santa Clarita (City) is working on ways to improve and increase its circulation of, and accessibility to, information that pertains to the floodplain in an effort to better educate and assist its citizens about developing and living in the floodplain. Please take the time to read the information below, and if you have further questions, or would like additional information, a variety of contact information has been supplied at the end of this document. Overview The City features one large river and several smaller tributaries or streams, which are susceptible to annual flooding events, pose threats to life and safety, and cause significant property damage. The main river is the Santa Clara River while streams include Bouquet Canyon Creek, San Francisquito Creek, Piacerita Creek, Newhall Creek, Railroad Canyon Creek, Mint Canyon Creek, Sand Canyon Creek, Iron Canyon Creek and the South Fork of the Santa Clara River. The City has approximately 3,600 acres of floodplain and nearly 4,400 individual parcels that are partially or entirely located within the floodplain. Runoff from storm events in the surrounding watershed contributes substantially to flooding, and ongoing development within the City continues to displace natural areas that have historically functioned as flood storage. Recent Flooding Events The flooding and associated landslide events in January and February of 2005 represent the most recent significant flooding in the Santa Clarita Valley. Average annual rainfall for the valley is typically around 17 inches and in the early part of 2005, the City experienced over 42 inches of rainfall. Damage was mostly limited to banks along San Francisquito Creek, Newhall Creek and the Santa Clara River. Trail systems that are directly adjacent to the San Francisquito Creek and the Santa Clara River were washed out in areas that did not have buried bank stabilization. The Polynesian Mobile Home Park which is located adjacent to Newhall Creek experienced up to four feet of flooding when the banks of Newhall Creek were overtopped. The Sand Canyon Mobile Home Park lost one residence where approximately 75 feet of bank eroded away prior to reaching the mobile home. Claims filed under the Federal Emergency Management Agency (FEMA) National Flood Insurance Program (NFIP) from the City were approximately $2.5 million. Although the floods of 2005 represented a larger scale event, they are not unprecedented within the recent past. The floods in February 1998, January and February 1995 and the winter storms Flood Hazards in the City of Santa Clarita �J - in 1992 all caused severe flooding and resulted in FEMA declaring Los Angeles County a disaster area. Causes of Flooding in the Santa,Clarita Valley Flooding occurs when climate (or weather patterns), geology and hydrology combine to create conditions where river and stream waters flow outside of their usual course and "overspill" beyond their banks. In the Santa Clarita Valley; the combination of these factors, augmented by ongoing, development create seasonal flooding conditions. Two types of flooding primarily affect the Santa Clarita Valley; riverine flooding and urban flooding. Riverine flooding is the overbank flooding of rivers and streams. Flooding in large river systems typically results from large scale weather systems that generate prolonged rainfall over a wide geographic area, causing flooding in hundreds of smaller streams, which then drain into the major rivers. In addition, any low-lying area has the potential to flood. The flooding of developed areas may occur when the amount of water generated from rainfall and runoff exceeds a storm water system's (channel or storm drain) capacity to remove it. The Santa Clara River and its tributary streams play a major part in moving the large volume of runoff that is generated from the valley and surrounding foothills and mountains. The drainage system, including natural streams as well as constructed storm drain infrastructure within City and County areas, is adequate to handle normal precipitation in the region (15-19 inches per year). With the rapid urbanization of the Santa Clarita Valley since 1960, storm water volumes have increased due to increased impervious surface area from parking lots, rooftops and streets. FIood control facilities have been: ponstructed to mitigate the impacts of development on drainage patterns, including flood control channels, debris basins and runoff control systems. Flood Insurance The City participates in the NFIP that makes available federally backed flood insurance for all structures, whether or not they are located within the floodplain. More than 25 percent of NFIP claims are fled by properties located outside the 100-year floodplain, also known as the Special Flood Hazard Area (SFHA). Following the purchase of flood insurance, the NFIP imposes a 30- day waiting period, so residents should purchase insurance before the onset of the rainy season to ensure coverage during the flooding season. Please be aware that standard homeowner or renter insurance policies do not cover losses due to flooding. Membership within NFIP, and the availability to City residents of flood insurance, requires the City to manage its floodplains in ways that meet or exceed standards set by FEMA. The NFIP insures buildings with two types of coverage: structural and contents. Structural coverage includes walls, floors, insulation, furnace and other items permanently attached to the structure. Contents coverage may be purchased separately to cover the contents of an insurable building. FIood insurance also pays a portion of the costs of actions taken to prevent flood damage. Since July 1, 1997, all NFIP policies include Increased Cost of Compliance coverage that assists with bringing structures into compliance with current building standards, such as elevating structures 1 foot or more above the height of the one -percent annual chance flood. The limit of this coverage is $30,000. Federal financial assistance requires the purchase of flood insurance for buildings located within the SFHA; a requirement that affects nearly all mortgages financed through commercial lending Flood Hazards in the City of Santa Clarita L__ t'rino, Inc.

In addition, the proposed project includes a road extension that would connect the proposed Dockweiler Drive extension with Lyons Avenue. This extension would include a proposed bridge crossing of Newhall Creek (Figure 1). The proposed bridge will be comprised of four 25-foot-wide and 8-foot-deep openings in a concrete box bridge at the crossing of the Newhall Creek channel and the channel improvement to trapezoidal sections with 80-foot-wide soft base and 2:1 slopes. Elevations on the project site range from approximately 1,260 to 1,285 feet and the project site totals approximately 6.67 acres. Approximately 2 acres of this area is already paved or otherwise developed. 2.0 INTRODUCTION This report summarizes the methods and results of a literature search and field investigations conducted by Impact Sciences, Inc. These investigations focused on the identification of biological resources existing or potentially occurring on the project site. The purpose of this report is to provide the project applicant, the City of Santa Clarita (City), and reviewing regulatory agencies information regarding current on -site biological resources, the suitability of on -site habitats to support sensitive biological resources, and analyze impacts to these resources should the project be implemented. 3.0 METHODS 3.1 Project Site Descriptions Due to the irregular shape of the proposed project, several terms are used to describe the project site in this report. "Project site" is defined as the disturbance area associated with the proposed project inclusive of the road right-of-way and adjacent areas disturbed by grading. "Project area" includes the project site as well as a 200 foot buffer occurring on either side of the grading limit line. The "project region' includes the Newhall, California US Geologic Survey (USGS) 7.5-minute quadrangle, in which the project site is located, as well as the following eight surrounding quadrangles: Mint Canyon, Green Valley, Warm Springs Mountain, Whitaker Peak, Val Verde, Santa Susana, Oat Mountain, and San Fernando. 3.2 Literature Search Prior to any field investigations, documentation pertinent to biological resources that may occur on and near the proposed project site were reviewed and analyzed. Data sources reviewed included: (1) the Impact Sciences, Inc. 1 Dockweiler Road Extension Project 1186.001 April 2015 Biological Assessment Federal Register listing package for the federally listed species known to occur in the areal (2) literature pertaining to habitat requirements of sensitive species potentially occurring on the project site; (3) the most recent updates of California Natural Diversity Data Base2 (CNDDB) information regarding sensitive species potentially occurring on and near the project site; and (4) the most recent updates of the California Native Plant Society3 (CNPS) database. The CNPS database query focused on the project region and as such, included the Newhall, California USGS 7.5-minute quadrangle, in which the project site is located, as well as the surrounding Mint Canyon, Green Valley, Warm Springs Mountain, Whitaker Peak, Val Verde, Santa Susana, Oat Mountain and San Fernando quadrangles. Additional information pertinent to biological resources that may occur within the project site, area, and region was also reviewed and analyzed.

Although focused special -status plant surveys were not conducted specifically for this project, they were conducted in spring of 2014 on the adjacent Masters College site situated to the east and included the eastern portion of this project's boundaries. Similarly, focused US Fish and Wildlife Service (USFWS) protocol surveys for California gnatcatcher were performed on the adjacent Master's College site and the survey reach did extend to the west and included all suitable habitats within the project area associated with the proposed Dockweiler Road extension project. 4.0 RESULTS 4.1 General As described, the proposed project involves the extension of Dockweiler Drive from the Masters College site generally northward, connecting with the existing Arch Street at its intersection with Placerita Canyon Road and 12th Street. In addition, the proposed project includes a road extension that would connect the proposed Dockweiler Drive extension with Lyons Avenue. This extension would include a proposed bridge crossing of Newhall Creek (Figure 1). As described above, elevations on -site range from approximately 1,260 to 1,285 feet and the project site totals approximately 2.32 acres. Existing land uses in the vicinity of the project site include railroad tracks and a train station to the south, industrial and commercial development to the southwest, west, and northwest and north. Rural residential land uses occur to the northeast and undeveloped open space occurs east of the project site. 4.2 Literature Search The literature search indicated several special -status plant and wildlife species have been recorded from the project region. Only observed species and those with a moderate to high potential of occurrence on the project site or area are described in this report. However, all species defined within a nine -quad search, including the project site, are presented, and analyzed in the Special Status Species Tables (Appendices A and B). Impact Sciences, Inc. 5 Dockweiler Road Extension Project 1186.001 April 2015 Biological Assessment Special status species include species listed as endangered, threatened, or rare under the federal or state Endangered Species Acts, Candidate Species for listing as endangered or threatened, California Fully Protected Species, and, pursuant to California Environmental Quality Act (CEQA) Guidelines Section 15380(d), all other species tracked by the California Natural Diversity Database (CNDDB) which are considered by the California Department of Fish and Wildlife (CDFW) to be those species of greatest conservation concern. Plant species with a California Rare Plant Rank (Rank) of 1 (plants presumed extinct in California, or rare, threatened, or endangered in California and elsewhere), Rank 2 (plants that are rare, threatened, or endangered in California but more common elsewhere), or Rank 4 (plants of limited distribution in California) are included in this definition. Plant species with a Rare Plant Rank of 3 (plants for which insufficient information is available to determine their status) are not included in this definition. Species tracked by the CNDDB are listed in CDFW's lists of Special Plants and Special Animals. 4.3 Field Surveys 4.3.1 Vegetation Communities Seven distinct native vegetation communities were identified within the project site. In descending order of prevalence, these include chamise chaparral, rubber rabbitbrush scrub, scale broom/mulefat scrub, California sagebrush/California buckwheat scrub, scale broom scrub, coast prickly pear scrub, and narrow -leaf willow thicket. Developed and disturbed areas were also mapped, and include developed/ornamental landscaping, cleared/disturbed areas, exotic trees, and components of the native plant communities listed above (Figure 2). Each of these vegetation communities is described below. Chamise Chaparral (Adenostoma fasciculatum) Alliance (1.64 acres) This is the dominant native vegetation association within the project site. This community is dominated by chamise along with gray California buckwheat (Eriogonum fasciculatum var. polifolium), occasional chaparral yucca (Hesperoyucca whipplei). This alliance dominates the southeastern portion of the site and includes a small pocket of coast prickly pear cactus scrub (Opuntia littoralis). Disturbed Chamise Chaparral (0.32 acre) An area of Disturbed Chamise Chaparral Alliance also occurs in the southeastern portion of the site, adjacent to cleared/disturbed areas. Impact Sciences, Inc. 6 Dockweiler Road Extension Project 1186.001 April 2015 Biological Assessment Rubber Rabbitbrush (Ericaineria nauseosa) Scrub Alliance (0.74 acre) This Alliance is dominated by rubber rabbitbrush, along with occasional big sagebrush (Artemisia tridentata) and California buckwheat (Eriogonum fasciculatum) and occurs in three areas of the site. Rubber rabbitbrush is a fast-growing shrub that develops quickly after disturbance. Scalebroom—Mulefat Scrub (Lepidospartum squamatum—Baccharis salicifolia Shrubland Alliance) (0.43 acre) Scalebroom-mulefat scrub occurs on the banks (0.32 acre) and in the active channel of Newhall Creek (0.11 acre). Dominant plants present within this alliance include scalebroom and mulefat, occurring together in densities ranging from 10 percent to 40 percent cover. Figure 2 illustrates the separation, but for the purposes of this discussion, it is considered one habitat. Vegetation is sparse within the Newhall Creek channel. The most common species include scalebroom and mulefat, together resulting in less than 10 percent cover. With the exception of a small cluster of narrow -leaf willow (described below), the creek channel is characterized as a scoured sandy streambed. California Sagebrush -California Buckwheat Scrub (Artemisia californica-Eriogonum fasciculatum Shrubland Alliance) (0.18 acre) The area identified as California Sagebrush -California Buckwheat Scrub supports approximately 80 percent native cover where it occurs on a south -facing slope above Newhall Creek in the southwestern portion of the project site. Sawyer and Keeler -Wolf describe this plant community as Artemisia californica- Eriogonum fasciculatum Shrubland Alliance since the dominant shrub is California sagebrush and the co - dominant shrub is California buckwheat. Other shrubs present include chamise (Adenostoma fasciculatum), black sage (Salvia mellifera), non-native grasses and forbs such as wild oats (Avena sp.), and brome (e.g., Bromus sp.). Disturbed California Sagebrush -California Buckwheat Scrub (1.28 acres) An additional area of disturbed California Sagebrush -California Buckwheat Scrub occurs near the center of the site. This community has undergone disturbance in the recent past, evidenced by the sparse nature of the vegetation and influx of non-native species. Remnants of California sagebrush and California buckwheat remain, though the area is now co -dominated by non-native grasses and forbs including summer mustard (Hirschfeldia incana), tree tobacco (Nicotiana glauca) and yellow star thistle (Centaurea solstitialis). The weedy native cocklebur (Xanthium strumarium) is also present.

This community includes a few scattered mulefat and big sagebrush (Artemisia tridentata) shrubs. Coast Prickly Pear Scrub - Opuntia littoralis Shrubland Alliance (0.015 acre) One small patch of coast prickly pear is found in the extreme southeast extent of the property, surrounded entirely by chamise chaparral. Narrow -Leaf (Sandbar) Willow Thickets - Salix exigua Shrubland Alliance (0.007 acre) Narrow -leaf willows occur in a small stand (25 feet x 12 feet) within the alignment of the proposed bridge. While this species is a wetland indicator, other wetland indicators are absent. The vegetation occurs on the opposite side of Newhall Creek from the ephemeral tributary, and likely receives periodic dry -season runoff from streets to the west. Coast Live Oak (0.008 acre) Two coast live oak trees (Quercus agrifolia) occur along with one blue elderberry (Sambucus nigra ssp. caerulea) immediately adjacent to and outside the development limits along Newhall Creek, north of the proposed bridge location. Developed/Ornamental Landscaping (1.98 acre) These areas support structures, pavement, or non-native ornamental landscaping associated with development. This is the second largest vegetation association within the project site. Two small clusters of non-native locust trees (Robinia sp.) are situated within the project site, between the railroad tracks and Newhall Creek in the southern portion of the project site, and occupy approximately 178 square feet (0.004 acre). These exotic (non-native) either volunteered or where planted. This species is considered undesirable because of its tendency to invade natural areas where it may out -compete native plants. Cleared/Disturbed Areas (0.46 acre) This area occurs in several small locations generally in the southern portion of the site. These areas are nearly devoid of vegetation, supporting mostly open bare soil. Impact Sciences, Inc. 9 Dockweiler Road Extension Project 1186.001 April 2015 Biological Assessment 4.3.2 Wildlife Weather during the surveys was warm and clear, providing conditions suitable for high wildlife activity. However, due to the relatively small size of the project site and area, combined with the presence of nearby urban development and the associated human disturbance, wildlife diversity on the project site is relatively low. The only reptile observed on site was side -blotched lizard (Uta stansburiana). Tracks, scat, burrows, and other sign observed indicate the presence of California ground squirrel (Spermophilus beecheyi) and Botta s pocket gopher (Thomomys bottae). Common bird species recorded during the field surveys included mourning dove (Zenaida macroura), American crow (Corvus brachyrhynchos), California towhee (Melozone crissalis), house finch (Haemorhous mexicanus), and Says phoebe (Sayornis saya). All of these species are relatively tolerant of human encroachment. Several additional avian species are expected to occur on site seasonally. Small rodents including Botta's pocket gopher (Thomomys bottae) and deer mouse (Peromyscus maniculatus) are likely present and evidence of California ground squirrel (Otospermophilus beecheyi) and evidence of coyote (Canis latrans) were observed. 4.3.3 Wildlife Movement Habitat used by wildlife as a movement corridor generally link large areas of open space that are otherwise separated by rugged terrain, changes in vegetation, human disturbance, or the encroachment of urban development. The fragmentation of natural habitat creates isolated 'islands' of vegetation that may not individually provide sufficient area to accommodate sustainable populations and can adversely impact genetic and species diversity. Corridors mitigate the effects of this fragmentation by: (1) allowing animals to move between remaining habitats, which allows depleted populations to be replenished and promotes genetic exchange with separate populations; (2) provide escape routes from fire, predators, and human disturbances, thus reducing the risk that catastrophic events (such as fire, flood, or disease) will result in population or species extinction; and (3) serving as travel paths for animals that require larger home ranges to meet their normal requirements of food, water and cover. The proposed project site is generally surrounded on three sides by development, including road networks. However, Newhall Creek provides a passage through the developed areas between the Santa Clara River and the Angeles National Forest to the southeast. Stream corridors in general are considered important movement corridors for wildlife, because they provide water, food, and often cover by riparian vegetation for protection from predators. On and near the proposed project site Newhall Creek does not flow year-round. Riparian vegetation on the project site is limited to sparse shrubs, and steep banks on the project site also limit available cover. However, Newhall Creek does provide, as stated above, a connection between the Santa Clara River and the Angeles National Forest to the southeast. Although, much of the length of the creek occurs adjacent to Impact Sciences, Inc. 10 Dockweiler Road Extension Project 1186.001 April 2015 Biological Assessment dense development and wildlife activity is expected to be somewhat limited, Newhall Creek is considered part of a wildlife movement or migration corridor that connects larger areas of natural open space. 4.3.4 Special -Status Plant and Animal Resources Based upon review of the California Natural Diversity Database (CNDDB) database for special -status plant species of the Newhall, California and eight adjacent quadrangles, 37 special -status plant and 39 special -status animal species have been reported from the region. The potential for special -status species to occur on the project site is based on the proximity of the project site to previously recorded occurrences in the CNDDB database, habitat requirements of each species, evaluation of on -site vegetation and habitat quality, topography, elevation, soils, surrounding land uses, and geographic ranges of special -status plant and wildlife species known to occur in the region. Potential special -status plant species that may occur on project site is summarized in Appendix A, Special -Status Plant Species Recorded from the Project Region. Likewise, special status wildlife species recorded in the region that may occur on the project site are summarized in Appendix B, Special -Status Wildlife Species Recorded from the Project Region. The occurrence potential described in Appendices A and B are classified according to the following: Not Expected: There is no suitable habitat present on the proposed project site (i.e., habitats on the proposed project site are clearly unsuitable for the species requirements [e.g., foraging, breeding, cover, substrate, elevation hydrology, plant community, disturbance regime, etc.]). The species has an extremely low probability of being found on the proposed project site and no further surveys are required. Low Potential: Either significantly limited quantity and/or quality of suitable habitat is present on the proposed project site (i.e., not enough area of the habitat is present to support the species, few of the habitat components meeting the species requirements are present and/or the majority of habitat on the proposed project site is unsuitable or of very low quality). There are no or few recent known records of occurrence in the near vicinity of the proposed project site. The species has a low probability of being found on the proposed project site and no further surveys are required. Moderate Potential: Some suitable habitat is present on the proposed project site (i.e., some of the habitat components meeting the species requirements are present and/or the quantity the habitat on the proposed project site is marginal). Additionally, there are known records of occurrences in the region of the proposed project site, but not necessarily in the immediate vicinity. The species has a moderate probability of being found on the proposed project site and additional surveys may be required. High Potential: Suitable quantity and quality of habitat is present on the proposed project site (i.e., all habitat components meeting the species requirements are present and/or habitat(s) on the proposed project site is highly suitable or of high quality). Additionally, there are recent known Impact Sciences, Inc. 11 Dockweiler Road Extension Project 1186.001 April 2015 Biological Assessment records of occurrences in the vicinity of the proposed project site. Species having a high probability of being found on the proposed project site may require additional surveys to fully determine presencelabsence. Present: Species was observed on the proposed project site during surveys associated with this report or by other persons. 4.3.4.1 Special -Status Plants Based on habitat conditions and the small size of the proposed project site, only general botanical surveys were conducted on project site and area. Focused rare plant surveys were performed adjacent to and east of the project site. The only special -status plants observed during the field investigations were two coast live oaks. No other special -status plants are considered to have a high potential for occurrence within the project site. Native oak trees are protected under City of Santa Clarita Oak Tree Ordinance (Ordinance No. 89-10 passed by the City Council on April 25, 1989). A permit is required for encroachment into the Protected Zone, defined as 5 feet outside the dripline and further defined as extending no less than 15 feet outward from the trunk of an oak tree. 4.3.4.2 Special -Status Wildlife No special -status wildlife species were directly observed during field investigations conducted on the proposed project site or area. Although Newhall Creek traverses the project site, it is considered a seasonal drainage, and it is apparent within the project site, when flows do occur, they are rapid enough to scour the channel. Therefore, none of the special -status fish defined in Appendix B are expected to occur on site, with the possible exception of a potential temporary presence after storm events. Likewise, aquatic conditions are not suitable for special -status amphibians defined in Appendix B. In most areas of the proposed project site the banks of Newhall Creek are too severe for amphibians to traverse. As such, they too are expected to have no more than a low potential for occurrence. Some of the more highly motile species such as birds and bats may briefly and infrequently occur on site to forage. However, there is no on -site habitat of a size or quality that could reasonably support a sustainable resident population of any of the special -status wildlife species identified in Appendix B. Notwithstanding, one special -status reptile is considered to have a moderate potential to occur on site. Silvery legless lizard (Anniella pulchra pulchra), California Species of Special Concern. This small lizard is often mistaken for a snake or worm since, as it has no limbs. Silvery legless lizard spends most of its life below surface soils where it forages on insects and larvae. It is most commonly found in and around the roots of trees and shrubs, often beneath leaf litter where its prey is most abundant. Moisture is a key ingredient in its habitat requirement. Silvery legless lizards will dig deeper into the soils to reach the Impact Sciences, Inc. 12 Dockweiler Road Extension Project 1186.001 April 2015 Biological Assessment correct moisture level. As such, this species is rarely observed unless one actively seeks it out. Though apparently very dry at the surface, some of areas within the project site may have sub -surface soils with the moisture content necessary to support this species. Therefore silvery legless lizard is considered to have a moderate potential for occurrence on the proposed project site. 4.3.5 Jurisdictional Waters, Streambed, and Riparian Resources The portion of Newhall Creek present on the proposed project site is under the jurisdictional authority of federal and state regulatory agencies. Impacts to "Waters," streambeds and adjacent riparian vegetation, as defined in the regulations cited below, typically require authorizations from these agencies. Regulatory agencies and the limits of their jurisdiction are discussed below. 4.3.5.1 US Army Corps of Engineers (USAGE) Federal regulations of "Waters of the United States" stem from Section 10 of the Federal Rivers and Harbors Act of 1899, enacted to regulate activities within navigable waters. In 1972, the federal Clean Water Act was passed. This act regulates discharges into Waters of the United States and Section 404 of this act regulates activities including fills placed into wetlands that are adjacent to navigable waters. Waters of the United States are defined in 33 CFR 328.3(a) as: • All waters that are currently used, were used in the past, or may be susceptible to use in interstate or foreign commerce, including all waters that are subject to the ebb and flow of the tide. • All interstate waters including interstate wetlands. • All other waters such as intrastate lakes, rivers, streams (including intermittent streams), mudflats, potholes, wet meadows, playa lakes, or natural ponds, the use, degradation or destruction of which could affect interstate or foreign commerce including any such waters. • Waters that are or could be used by interstate or foreign travelers for recreational or other purposes. • Waters from which fish or shellfish are or could be taken and sold in interstate or foreign commerce. • Waters that are used or could be used for industrial purpose by industries in interstate commerce. • All impoundments of waters otherwise defined as Waters of the US under the definition. • The territorial seas. • Tributaries of Waters of the US. • Wetlands adjacent to Waters of the US. Impact Sciences, Inc. 13 Dockweiler Road Extension Project 1186.001 April 2015 Biological Assessment USACE jurisdiction in non -tidal waters typically extends to the ordinary high water mark (OHWM). The OHWM for intermittent streams, for example, can be determined by "the fluctuations of water as indicated by physical characteristics such as clear, natural lines impressed on the bank, shelving, changes in the character of soil, destruction of terrestrial vegetation, the presence of litter and debris, or other appropriate means that consider the characteristics of the surrounding areas" (33 CFR 328.3(e)). In and areas of the southwest, the OHWM may occur at a lower level than where the typical physical indicators are present, due to unusually high flows not occurring on a typical annual cycle (Allen, et al. 2001). Most impacts to areas delineated as Waters of the United States, if determined to be jurisdictional by the USACE, require a project to obtain approval under the authority of the Clean Water Act and its implementing regulations. 4.3.5.2 California Department of Fish and Wildlife (CDFW) The State of California regulates water resources under Sections 1600 to 1619 of the Fish and Game Code of California. Section 1602 mandates that: An entity may not substantially divert or obstruct the natural flow of, or substantially change or use any material from the bed, channel, or bank of any river, stream, or lake or dispose of debris, waste, or other material where it may pass into any river stream, or lake. Unless certain requirements are met, CDFW considers most natural drainages to be streambeds unless it can be demonstrated otherwise. Streambeds are defined in the California Code of Regulations Title 14, Chapter 1, Section 1.72 as follows: A stream is a body of water that flows at least periodically or intermittently through a bed or channel having banks and that support fish or other aquatic life. This includes watercourses having surface or subsurface flow that supports or has supported riparian vegetation. CDFW jurisdiction includes ephemeral, intermittent, and perennial watercourses, and is often extended to the limit of riparian habitats that are located contiguous to the water resource that function as part of the watercourse system. In this analysis, the area generally corresponding to the limit of riparian habitats located contiguous to the water resource is referred to as the "resource line." Section 2785(e) of the Fish and Game Code of California states: Riparian habitat means lands which contain habitat which grows close to and which depends on soil moisture from a nearby freshwater source. 4.3.5.3 Regional Water Quality Control Board Section 401 of the Federal Clean Water Act authorizes the State of California to certify federal permits and licenses. The state's implementing regulations to conduct certifications are codified under the California Impact Sciences, Inc. 14 Dockweiler Road Extension Project 1186.001 April 2015 Biological Assessment Code of Regulations Title 23 Waters, Sections 3830-3869. Projects qualifying for an USACE Section 404 Permit must submit materials for review to the appropriate Regional Water Quality Control Board (RWQCB) and request a Section 401 Certification. Much of the same information (project description, potential impacts, and mitigation measures) necessary to apply for USACE Section 404 and Fish and Game Code Section 1603 Permits is required for the Section 401 Certification. Direct and indirect impacts on wetland and riparian areas may also be subject to the jurisdiction of several additional state and federal agencies, including the Los Angeles RWQCB. 4.3.6 Delineation Results A delineation of regulatory agency jurisdictional limits was performed in September 2013 (Appendix C). A map illustrating the topography of the region, as well as photographs showing the project site are provided in Appendix C. Figure 4 shows the vegetation and jurisdictional features in the survey area. Two jurisdictional features are defined within the project site, area, and region: 1. Newhall Creek, upstream of its confluence with Placerita Creek and the south fork of the Santa Clara River. This creek is mapped by the USGS as a "blue -line" intermittent stream. On and near the project site the direction of flow is from southeast to northwest. Banks of the creek are nearly vertical, with the south bank containing artificial fill (pieces of concrete and asphalt). Railroad tracks and Railroad Avenue are situated to the west, beyond the top of the bank. Areas immediately east of the creek are vacant except for an industrial yard northeast of the proposed bridge location. No surface water was present during the April survey and sparse vegetation cover within the channel indicates frequent scour during the rainy season. Therefore, this wetland feature on the project site is best described as intermittent riverine, relatively permanent water (RPW) that has seasonal continuous flow, is a tributary to the Santa Clara River which flows into the Pacific Ocean, and can be defined as a traditionally navigable water (TNW). On the project site, vegetation and surface features indicate that seasonal flows migrate across the entire channel, which averages 35 feet in width at the base (federal jurisdiction). The distance between the tops of the banks (limits of state jurisdiction) average approximately 100 feet. No indicators of prolonged water saturation or ponding, such as surface mud cracks, were observed on site during the field survey. 2. Un-named ephemeral tributary to Newhall Creek. This narrow tributary is about 3.5 feet in width at its base (federal jurisdiction) and is entirely within state jurisdiction over Newhall Creek. It is assumed that flow from this tributary enters the project area from a culvert underneath the railroad tracks and Railroad Avenue (this could not be confirmed during the survey due to presence of a homeless camp at the presumed culvert location). The distinct bed and bank structure of this feature, and regional topography, indicate this tributary is more than a "gully" resulting from localized erosion. Wetland indicators are absent from this feature. Impact Sciences, Inc. 15 Dockweiler Road Extension Project 1186.001 April 2015 Biological Assessment Appendix C provides details regarding the vegetation occurring within the delineation survey boundaries. Of the vegetation identified in this area, only narrow -leaf willow thicket is a wetland indicator (Salix exigua — Facultative Wet). However, it is concluded that this thicket is probably not a jurisdictional wetland at the federal or state level. More detail is provided in the discussion that follows. 4.3.7 Wetland Determination 4.3.7.1 Federal Hydrology and soils present in the project area and site (floodplains/gravel bars and sand) are naturally problematic for wetland delineation. The following paragraphs include excerpts (in italics) from the Arid West supplements of the wetland determination procedure for problematic sites where soils may meet the definition of a hydric soil but do not exhibit typical indicators. Our observations are described for each step of the procedure. 1. Verify that one or more indicators of hydrophytic vegetation are present or that the vegetation is disturbed or problematic. If so, proceed to step 2. Site observations: Narrow -leaf willow has an indicator ranking for the Arid West of Facultative Wetland. Therefore, it can be concluded hydrophytic vegetation is present. 2. Verify that at least one primary or two secondary indicators of wetland hydrology are present or that indicators are absent due to disturbance or other factors. If so, proceed to step 3. If indicators of hydrophytic vegetation and/or wetland hydrology are absent, then the area is probably no -wetland and no further analysis is required. Site observations: No other primary indicators of wetland hydrology are present. Only one secondary indicator of wetland hydrology (dominance of Facultative Wet vegetation) is present. Based on this information, and the observation that redoximorphic soil features are sparse and, where present, are faintly expressed, it can be concluded that the willow thicket (300 square feet or 0.007 acre) is probably not a federally jurisdictional wetland. Unfortunately, the Arid West procedure does not allow for a more definitive conclusion. 4.3.7.2 State According to the wetland definition at the state level, it is concluded that the narrow -leaf willow thicket would not meet the definition of wetland. While narrow -leaf willow is a hydrophyte, there is no evidence of continuous or recurrent saturation of the upper substrate and no evidence of anaerobic conditions are present. 5 USACE, 2008. Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Arid West Region (Version 2.0). Report No. ERDC/EL TR-08-28, issued September 2008. Impact Sciences, Inc. 16 Dockweiler Road Extension Project 1186.001 April 2015 Biological Assessment 4.3.8 Non -Wetland Jurisdiction The proposed bridge will impact Newhall Creek in a section of the creek that is classified as "riverine and relatively permanent water, with continuous flow at least seasonally." The bridge may also impact a narrow, ephemeral tributary to Newhall Creek. The extent of permanent and temporary construction impacts need to be known in order to provide a more precise analysis of impacts. 5.0 PROJECT IMPACTS 5.1 Methodology Direct impacts of a proposed project on biological resources typically involve the loss, modification, or disturbance of natural habitat (i.e., plant communities or other naturally occurring areas) which in turn, directly and indirectly affect plant and wildlife species dependent on that habitat. The significance of potential impacts on biological resource is determined by an evaluation of the overall biological value of a habitat area in comparison with significance threshold criteria that are described below. The relative value of each of the plant communities present on site is measured by such factors as disturbance history, biological diversity, importance to particular plant and wildlife species, uniqueness or sensitivity status, as well as the surrounding environment and the presence of special -status resources. The significance of impacts with respect to direct impacts on individuals or populations of plant and animal species takes into consideration the number of individual plants or animals potentially affected, how common or uncommon the species is both on the project site and from a regional perspective, and the sensitivity status if the species is considered special status by resource agencies. These factors are evaluated based on the results of on -site biological surveys and studies, results of literature and database reviews, and established and recognized ecological and biodiversity theories and assumptions. 5.2 Direct Impacts 5.2.1 Vegetation As described in Section 4.3.1, eight vegetation communities occur on the project site that include: California Sagebrush -California Buckwheat Scrub, Disturbed California Sagebrush- California Buckwheat Scrub, Scale Broom—Mulefat scrub, Scalebroom Scrub, Active Channel, Exotic Trees, Developed/Ornamental Landscaping, and Cleared (Figure 2). Site grading plans indicate that within the project site 2.32 acres of vegetation would be removed (100 percent of the vegetation resources present). Of the vegetation communities impacted Disturbed California Sagebrush -California Buckwheat Scrub is the dominant plant community present by area and approximately 0.63 acre of this habitat would be lost through site grading and project implementation. Impact Sciences, Inc. 17 Dockweiler Road Extension Project 1186.001 April 2015 Biological Assessment Due to its proximity to adjacent developed areas, the site has been subject to historic disturbances. Combined with its small size (2.32 acres), invasive plant species observed on the project site (e.g., mustard, tree tobacco, cocklebur, yellow star thistle) indicate a high percentage of plants that are generally associated with ruderal or highly disturbed places. The loss of 2.32 acres of vegetation on the project site is considered adverse. However, due to the disturbance history, its small size, the lack of sensitive plant communities, the lack of structure for wildlife, and high percentage of invasive and non-native plant species generally associated with disturbed areas, impacts associated with the loss of 2.32 acres of vegetation present on -site is considered less than significant. 5.2.2 Wildlife Construction activity and grading operations of the proposed project would disturb and/or threaten the survival of common wildlife species present. Some species would be expected to relocate to other areas of similar habitat within the local area. However, wildlife that migrates to off -site areas is vulnerable to mortality by predation, potential conflicts with people and cars, and unsuccessful competition for food and territory. It is expected that species of low mobility (particularly small mammals, amphibians, and reptiles) would be lost during site preparation, grading, and construction. Site grading and project implementation would eliminate approximately 2.32 acres of natural habitat present on -site, and would result in an incremental reduction in native wildlife species abundance and diversity. However, due to nearby urban development and the associated human disturbance, field investigations indicate wildlife diversity and abundance on the project site is relatively low. The only reptile observed on site was side -blotched lizard (Uta stansburiana). Tracks, scat, burrows, and other sign observed indicate the presence of California ground squirrel (Spermophilus beecheyi) and Botta s pocket gopher (Thomomys bottae). Small rodents including deer mouse (Peromyscus maniculatus) are likely also present and evidence of coyote (Canis latrans) was observed. Common bird species recorded during the field surveys included mourning dove (Zenaida macroura), American crow (Corvus brachyrhynchos), California towhee (Melozone crissalis), house finch (Haemorhous mexicanus), and Say's phoebe (Sayornis saya). All of these species are relatively tolerant of human encroachment. Several additional avian species are expected to occur on site seasonally. Because of the relatively common occurrence of these wildlife species that would be displaced or lost, project implementation is not expected to cause a current wildlife population on or adjacent to the project site to drop below self-sustaining levels. Therefore, impacts to common wildlife species is not considered significant. Impact Sciences, Inc. 18 Dockweiler Road Extension Project 1186.001 April 2015 Biological Assessment 5.3 Significance Threshold Criteria The City of Santa Clarita's Environmental Guidelines are the City's Thresholds of Significance for the purpose of CEQA. Because these guidelines incorporate all minimum thresholds of significance identified in the State CEQA Guidelines, thresholds of significance defined in Appendix G of the State CEQA Guidelines are not repeated here. 5.3.1 City of Santa Clarita Environmental Guidelines/Thresholds of Significance According to the City of Santa Clarita Environmental Guidelines, a project would have a significant effect on the environment if it would: • have a substantial adverse effect, either directly or through habitat modifications, on any species identified as a candidate, sensitive, or special -status species in local or regional plans, policies, or regulations or by the CDFW or USFWS; • have a substantial adverse effect on any riparian habitat or other sensitive natural community identified in local or regional plans, policies, or regulations or by the CDFW or USFWS; • have a substantial adverse effect on federally protected wetlands as defined by Section 404 of the Clean Water Act (including, but not limited to, marsh, vernal pool, coastal, etc.) through direct removal, filling, hydrological interruption, or other means; • interfere substantially with the movement of any native resident or migratory fish or wildlife species or with established native resident or migratory wildlife corridors, or impede the use of native wildlife nursery sites; • conflict with any local policies or ordinances protecting biological resources, such as a tree preservation policy or ordinance; or • conflict with the provisions of an adopted Habitat Conservation Plan, Natural Community Conservation Plan, or other approved local, regional, or state Habitat Conservation Plan. The first five criteria in the Santa Clarita Environmental Guidelines are addressed in the Direct Impacts analysis provided below. The sixth criterion is not relevant to the proposed project, because the project site is not located within an area defined as a Habitat Conservation Plan or Natural Community Conservation Plan. 5.3.2 Consistency with Defined Thresholds of Significance 5.3.2.1 Threshold 1 Will the project have a substantial adverse effect, either directly or through habitat modifications, on any species identified as a candidate, sensitive, or special -status species in local or regional plans, policies, or regulations or by the CDFW or USFWS? Impact Sciences, Inc. 19 Dockweiler Road Extension Project 1186.001 April 2015 Biological Assessment Analysis An assessment of biological resources present on the project site determined that one special -status wildlife species has a moderate potential to occur within the project site and could be directly impact through project implementation. Silvery legless lizard is a California species of special concern. On the project site, some limited habitat suitable for this species is present in the sandier terraces of Newhall Creek and possibly within the areas of scrub habitat north of the creek. This species is almost completely fossorial (i.e., occurring beneath the surface) and is dependent upon moisture levels in the soils where they live. During dry periods they will burrow deeper to find the necessary levels of moisture. As such, silvery legless lizard can be difficult to find, especially in dry seasons or years. Although sands within the Newhall Creek bed may currently be suitable for silvery legless lizard, they are unlikely to occur within the creek itself as it periodically supports storm flows and would scour any away legless lizards that could be seeking refuge. Therefore, the only suitable habitat remaining is a small area above the ordinary high water mark, north of the creek. This area may support individual species of silvery legless lizard, but is not likely to support a sustainable population. The grading plan indicates the areas north of the site would be disturbed during grading and project construction. Although it can be concluded that bridge construction associated with the proposed project would not impact populations of silvery legless lizard, disturbances associated with grading and implementation of the road extension may impact individuals of this California species of special concern. Therefore, impacts are considered significant without mitigation. Additionally, most native bird species when nesting, are protected by the Migratory Bird Treaty Act and the California Fish and Game Code, which prohibit the take (defined as destroy, harm, harass, etc.) of bird nests with eggs or young. Project -related activities associated with site preparation and construction could result in the direct loss of active nests or the abandonment of active nests by adult birds should grading occur during the nesting season. The loss of active bird nests would be in conflict with the Migratory Bird Treaty Act and the California Fish and Game Code. As such, impacts to active nests are a significant impact without mitigation. Conclusion Without mitigation, the project could result in potentially significant impacts to silvery legless lizard and active nesting birds. Implementation of Mitigation Measure BIO-1 and Mitigation Measure BIO-2 would reduce impacts to silvery legless lizard and nesting birds to a less than significant level. Impact Sciences, Inc. 20 Dockweiler Road Extension Project 1186.001 April 2015 Biological Assessment 5.3.2.2 Threshold BIO-2 Will the project have a substantial adverse effect on any riparian habitat or other sensitive natural community identified in local or regional plans, policies, or regulations or by the CDFW or USFWS? Analysis Riparian habitat or other habitat defined as significant does not occur on the project site or within the project area. Conclusion Given that riparian habitat is not present on site direct impacts would not occur and impacts are not considered significant. No mitigation is proposed or is required. 5.3.2.3 Threshold 13I0-3 Will the project have a substantial adverse effect on federally protected wetlands as defined by Section 404 of the Clean Water Act (including, but not limited to, marsh, vernal pool, coastal, etc.) through direct removal, filling, hydrological interruption, or other means? Analysis Based on field investigations, a small area of narrow -leaf willow thicket (300 square feet or 0.007 acre) is present. Where it occurs on -site, redoximorphic soil features are sparse and faintly expressed and as such the narrow -leaf willow thicket present on the project site is probably not a federally jurisdictional wetland. Further, according to the wetland definition at the state level, narrow -leaf willow thicket present on -site would not meet the criteria of wetland as defined by the State of California. While narrow -leaf willow is a hydrophyte, there is no evidence of continuous or recurrent saturation of the upper substrate and no evidence of anaerobic conditions are present. Two jurisdictional features do occur within the project site and area. Newhall Creek and a small ephemeral drainage that is a tributary to Newhall Creek occur on the project site and fall under the jurisdiction of the CDFW. Although these jurisdictional do not support riparian vegetation or sensitive wetland resources, Newhall Creek does support features that lie within the jurisdiction of CDFW. As discussed in above, the proposed bridge and associated infrastructure would result in both temporary and permanent impacts to areas of the Newhall Creek and its associated tributary and are classified as "riverine and relatively permanent water, with continuous flow at least seasonally" and as such are Impact Sciences, Inc. 21 Dockweiler Road Extension Project 1186.001 April 2015 Biological Assessment under CDFW jurisdiction. Without consultation with, and a formal agreement with CDFW, such impacts would be in violation of the Fish and Game Code and, are considered a significant impact. Conclusion Without mitigation, the project would result in potentially significant impacts to CDFW jurisdictional resources (i.e., Newhall Creek and its associated tributary). Mitigation Measure 13I0-3 would reduce impacts to jurisdictional resources to a less than significant level. 5.3.2.4 Threshold 13I04 Would the project, interfere substantially with the movement of any native resident or migratory fish or wildlife species or with established native resident or migratory wildlife corridors, or impede the use of native wildlife nursery sites Analysis The proposed project site is generally surrounded on three sides by development and road networks. However, Newhall Creek does extend through the site and provides a passage through developed areas between the Santa Clara River and the Angeles National Forest to the southeast. Stream corridors in general are considered important movement corridors for wildlife, because they provide water, food, and often cover by riparian vegetation for protection from predators. On and near the proposed project site Newhall Creek does not flow year-round. Riparian vegetation on the project site is limited to sparse shrubs, and steep banks on the project site limit cover. However, Newhall Creek does provide, as stated above, a connection between the Santa Clara River and the Angeles National Forest. Though much of the length of the creek occurs adjacent to dense development and wildlife activity is expected to be somewhat limited, Newhall Creek is considered part of a wildlife movement or migration corridor that connects larger areas of natural open space. To limit impacts to wildlife movement, an open span bridge is proposed where the proposed roadway extension crosses Newhall Creek. As designed, this bridge would not result in any barrier to wildlife movement and would serve to protect Newhall Creek as a functioning wildlife movement corridor. Conclusion The project as proposed would not result in significant impacts to wildlife movement. No mitigation measures are proposed or are required. Impact Sciences, Inc. 22 Dockweiler Road Extension Project 1186.001 April 2015 Biological Assessment 5.3.2.5 Threshold BIO-5 Would the project conflict with any local policies or ordinances protecting biological resources, such as a tree preservation policy or ordinance. Analysis The City of Santa Clarita Open Space Element includes several goals that focus on the preservation and protection of biological resources. Each relevant goal is defined below followed by an analysis of the consistency of this project with that goal of the Open Space Element. Goal 3: Goal 3 of the Santa Clarita General Plan Open Space and Conservation Element is "to protect significant ecological resources and ecosystems, including, but not limited to, sensitive flora and fauna habitat areas." Consistency: Riparian habitat or other sensitive biological habitat does not occur on the project site or within the project area. As such, no impact to riparian or sensitive other sensitive biological resources would occur as a result of project implementation. The project is consistent with Goal 3 of the City of Santa Clarita Open Space Element. Policy 3.1: Incorporate standards for a Significant Ecological Areas (SEA) Overlay Zone in the Municipal Zoning Code. Consistency: The project site does not occur in an area defined by the City of Santa Clarita as a Significant Ecological Area (SEA). Given that this project would not disturb any portion of a defined SEA the project is considered consisted with Policy 3.1 of the City of Santa Clarita Open Space Element. Policy 3.2: Encourage the preservation of oak woodlands, oak savannahs, and individually significant oak trees through enforcement and revisions to the Oak Tree Ordinance. Consistency: Oak trees, oak woodlands, or oak savannah do not occur on the project site and none would be directly or indirectly impacted by project implementation. Therefore, the project as proposed is considered consisted with Policy 3.2 of the City of Santa Clarita Open Space Element. Policy 3.7 Preserve to the extent feasible natural riparian habitat and ensure that adequate setback is provided between riparian habitat and surrounding urbanization. Impact Sciences, Inc. 23 Dockweiler Road Extension Project 1186.001 April 2015 Biological Assessment Consistency: Riparian habitat does not occur on the project site or within the project area. As such no impact to riparian habitat would occur as a result of project implementation. The project is consistent with Policy 3.7 of the City of Santa Clarita Open Space Element. Policy 3.10: Development shall consider to the extent feasible, preservation of wildlife corridors and provide adequate setbacks. Consistency: The proposed project site is generally surrounded on three sides by development, including road networks. However, Newhall Creek does extend through the site and provides a passage through developed areas between the Santa Clara River and the Angeles National Forest to the southeast. Stream corridors in general are considered important movement corridors for wildlife, because they provide water, food, and often cover by riparian vegetation for protection from predators. On and near the proposed project site, Newhall Creek does not flow year-round. Riparian vegetation on the project site is limited to sparse shrubs, and steep banks on the project site limit available cover. However, Newhall Creek does provide a connection between the Santa Clara River and the Angeles National Forest. Although, much of the length of the creek occurs adjacent to dense development in the vicinity of the project site, wildlife activity is expected to be somewhat limited. However, Newhall Creek is considered part of a wildlife movement or migration corridor that connects larger areas of natural open space. To limit impacts to wildlife movement, an open span bridge is proposed where the proposed roadway extension crosses Newhall Creek. As designed, this bridge would eliminate any barrier to wildlife movement and would serve to protect Newhall Creek as a functioning wildlife movement corridor. Therefore, the project as proposed would not result in direct or indirect impacts to wildlife movement and no mitigation measures are proposed or are required. Therefore, the project is consistent with Policy 3.7 of the City of Santa Clarita Open Space Element. 5.4 Indirect Impacts Indirect impacts to biological resources would occur in those habitat areas that remain proximal to the project site subsequent to project construction and operation. It is expected that implementation of the proposed project would result in indirect impacts to biological resources in the following ways: • Construction activity; • Increase in populations of non-native plant species; • Increased light and glare; Impact Sciences, Inc. 24 Dockweiler Road Extension Project 1186.001 April 2015 Biological Assessment • Stormwater runoff Indirect impacts associated with the proposed project are not quantifiable but are reasonably foreseeable. As such, the discussion that follows provides a common-sense identification of the types and magnitude of indirect or secondary impacts such that decision makers and the general public are aware of this project's indirect impact potential. This type of analysis is consistent with the requirements of CEQA. 5.4.1 Construction Activity Project construction (particularly site clearing and grading operations and implementation of the road surface) would have the potential to impact surrounding areas including adjacent plant communities and plant and animal species. Specifically, these impacts can include displacement and disturbance of wildlife, which could result in possible nest or den abandonment during the breeding season, siltation and erosion into drainages, excessive dust accumulation on vegetation that could result in the degradation or loss of some plant species, and soil compaction. Construction -related activities could have adverse effects on plant and wildlife habitat, and together, would be considered a significant impact. Implementation of Mitigation Measure BIO-4 would reduce these construction -related impacts to levels that are not considered significant. 5.4.2 Increase in Populations of Non -Native Species Subsequent to project completion, the number of non-native plant and wildlife species occurring in the vicinity of the roadway alignment would be expected to increase. These species are more adapted to urban environments could potentially displace native species because of their ability to compete more effectively for resources. Non-native plants tend to be more adaptable to urban or disturbed settings and can out -compete native plants for available resources. However, observations indicate historical and ongoing development in the vicinity of the project site have already supported continual and ongoing increases and proliferation of non-native plant and wildlife species populations in the area adjacent to the project site. Consequently, the proposed project is not expected to substantially increase the distribution of non-native plants and wildlife in adjacent open space areas situated to the east. Therefore, impacts to the remaining natural areas as a result of potential increases in non-native plants and wildlife resulting from project implementation are expected to be less than significant, given compliance with Mitigation Measure BIO-5. Impact Sciences, Inc. 25 Dockweiler Road Extension Project 1186.001 April 2015 Biological Assessment 5.4.3 Increased Light and Glare It is logical to assume that nighttime headlamp illumination would increase in areas adjacent to the project site. Nighttime light can disturb breeding and foraging behavior and can potentially alter breeding cycles of birds, mammals, and nocturnal invertebrates. Headlamp illumination could deter some animal species, especially the larger mammals, from using Newhall Creek as a wildlife movement corridor. If uncontrolled, such light could adversely impact the composition and behavior of the animal species that occur in these areas. The project site is currently surrounded on three sides by development, and much of the site and nearby natural area already receives some nighttime illumination from the adjacent urban areas. However, the project would increase light and glare effects proximal to the Newhall Creek corridor. Mitigation Measure BIO-6 would decrease this impact to less than significant. 5.4.4 Stormwater and Urban Runoff It is expected that stormwater runoff would be limited to pavement runoff during periodic storm events. Runoff from paved surfaces can increase eutrophication, deplete oxygen levels, increase long-term buildup of toxic compounds and heavy metals, and other adverse effects to biological resources associated with aquatic systems. Although this impact is not quantifiable, it is reasonable to assume runoff could substantially affect special -status species potentially occurring downstream from the project site and incrementally diminish habitat values for fish, wildlife, or plants, and degrade the quality of the environment. As described above, any runoff that flows into the Newhall Creek could result in increased eutrophication, depleted oxygen levels, long-term build-up of toxic compounds and heavy metals downstream as Newhall Creek connects to the Santa Clara River. Although potentially significant, the City's standard stormwater requirements are specifically designed to minimize these effects. Therefore, with implementation of the required design criteria, impacts to Newhall Creek resulting from stormwater runoff would be less than significant. 6.0 MITIGATION MEASURES Mitigation measures defined in defined below would eliminate impacts associated with this project to levels that are not considered significant. 6.1 Direct Impacts Mitigation Measures BIO-1: The applicant shall retain a qualified biologist with a CDFW Scientific Collection Permit and Memorandum of Understanding to conduct preconstruction surveys for the silvery Impact Sciences, Inc. 26 Dockweiler Road Extension Project 1186.001 April 2015 Biological Assessment legless lizard within the project site and area. In the event this species is located on the project site during preconstruction surveys all individuals shall be relocated, with the concurrence of the City and CDFW, to an approved site with suitable habitat. Surveys and relocation of silvery legless lizard may occur prior to construction; however, focused surveys must occur within 30 days prior to construction. Survey and relocation methods shall be approved by CDFW prior to commencement of grading. BI0-2: Active nests of native bird species are protected by the Migratory Bird Treaty Act (16 USC 704) and the California Fish and Game Code (Section 3503). If activities associated with construction or grading are planned during the bird nesting/breeding season, generally January through March for early nesting birds (e.g., Coopers hawks or hummingbirds) and from mid -March through September for most bird species, the applicant shall have a qualified biologist conduct surveys for active nests. The project management shall endeavor to avoid the breeding season. In the event it is not feasible to avoid the nesting season, a qualified biologist shall perform weekly nesting bird surveys beginning 30 days prior to initiation of ground - disturbing activities, with the last survey conducted no more than three days prior to the start of clearance/construction work. If ground -disturbing activities are delayed, additional pre -construction surveys shall be conducted so that no more than three days have elapsed between the survey and ground -disturbing activities. Surveys shall include examination of natural habitat for nesting birds. Several bird species such as killdeer and night hawks are known to nest on bare ground. Protected bird nests that are found within the construction zone shall be protected by a buffer deemed suitable by a qualified biologist, and verified by CDFW. Typically, a 300-foot buffer is required for most species and a 500-foot buffer for raptor species. Buffer areas shall be delineated with orange construction fencing or other exclusionary material that would inhibit access within the buffer zone. Installation of the exclusionary material delineating the buffer zone shall be verified by a qualified biologist prior to initiation of construction activities. The buffer zone shall remain intact and maintained while the nest is active (i.e., occupied or being constructed by the adults bird(s)) and until young birds have fledged and no continued use of the nest is observed, as determined by a qualified biologist. Impact Sciences, Inc. 27 Dockweiler Road Extension Project 1186.001 April 2015 Biological Assessment BI0-3: Prior to project construction, the following is required to mitigate impacts to jurisdictional resources: Areas of impact proposed by the project shall be calculated and permits for these proposed impacts shall be obtained (the discharge of fill into USACE jurisdictional areas will require a permit pursuant to Section 404 of the Clean Water Act and a 401 Certification from the State Water Resources Control Board, and any modification to a streambed, including removal of riparian vegetation, will require a streambed alteration agreement from CDFW pursuant to Section 1600 of the California Fish and Game Code). Both the streambed alteration agreement and the 401 and 404 permits will require specific mitigations for any impacts within their respective jurisdictions. Because the proposed bridge is a 'span' design, it does not require footings within the bed of the stream. However, plan designs do include approximately 450 feet of bank stabilization on both sides of the stream that would lie within CDFW, USACE and Regional Water Quality Control Board jurisdiction. Since little vegetation exists within this drainage, it is uncertain what mitigation these regulatory agencies may require. The stream in the impacted area would not be conductive to re -vegetation as the area of the project is deeply incised with little existing vegetation and newly planted vegetation would likely be washed away with the next storm event. Mitigation can be completed off site. Because there is essentially no riparian vegetation being removed with implementation of this project, revegetation off site, in a location approved by the City and CDFW, would be accomplished at a 1:1 area ratio. Upon City and agency approval of a suitable location, a detailed restoration plan shall be prepared that provides a planting palette, planting methods, and irrigation plan (as appropriate). The plan will also include a five-year monitoring effort to ensure success of the restoration effort. The monitoring plan will include monitoring methods, monitoring frequency, success criteria, and contingency actions should the success criteria not be met for any reason. Annual monitoring reports shall be provided to both CDFW and the City. Impact Sciences, Inc. 28 Dockweiler Road Extension Project 1186.001 April 2015 Biological Assessment BI0-4: The following guidelines shall be implemented to minimize impacts on remaining biological resources on the site as a result of construction and grading activities and to ensure that potential impacts on these resources will remain less than significant. A City -approved biologist shall be retained by the applicant as a construction monitor to ensure that incidental construction impacts on retained biological resources are avoided or minimized. Responsibilities of the construction monitor shall include the following: • Attend all pre -grading meetings to ensure that the timing and location of construction activities do not conflict with mitigation requirements. • Conduct meetings with the contractor and other key construction personnel, describing the importance of restricting work to within the project boundaries and outside of the preserved areas. The monitor shall also work with the contractor to determine the most appropriate staging/storage areas for equipment and materials. • Guide the contractor in marking/flagging the construction area limits, in accordance with the final approved grading plan. • Periodically and routinely visit the site during construction to coordinate and monitor compliance with the above provisions. The construction contractor shall install temporary erosion control measures to reduce impacts to and protect on site drainages from excess sedimentation, siltation, and erosion. These measures shall consist of minimization of existing vegetation removal; the use of temporary soil covers, such as hydro -seeding with native species, mulch/binder and erosion control blankets to protect exposed soil from wind and rain erosion; and/or the installation of silt fencing, berms, and dikes to protect storm drain inlets and drainages. No changing of oil or other fluids, or discarding of any trash or other construction waste materials shall occur on the project site. Vehicles carrying supplies, such as concrete, shall not be allowed to empty, clean out, or otherwise place materials into natural areas on or immediately adjacent to the site. Any equipment or vehicles driven and/or operated within or adjacent to drainages shall be checked and maintained daily, to prevent leaks of materials that if introduced to water could be deleterious to aquatic life. No equipment maintenance shall be conducted within the drainage channels or within 50 feet of channels. (Fuel -powered vehicles and equipment shall not be left idling or operated beyond periods needed to accomplish approved tasks.) Impact Sciences, Inc. 29 Dockweiler Road Extension Project 1186.001 April 2015 Biological Assessment Construction personnel shall be prohibited from entry into areas outside the designated construction area, except for necessary construction related activities, such as surveying. All such construction activities in or adjacent to remaining open space areas shall be coordinated with the project biologist. Standard dust control measures of the South Coast Air Quality Management District shall be implemented to reduce impacts on nearby plants and wildlife. This includes a variety of options to reduce dust including replacing ground cover in disturbed areas as quickly as possible, watering active sites regularly, and suspending all excavating and grading operations during periods of high winds. Upon completion of construction, the contractor shall be held responsible to restore any haul roads, access roads, or staging areas that are outside of approved grading limits. This restoration shall be done in consultation with the project biologist. BIO-5: Any landscaping plan(s) associated with the project shall be reviewed by a qualified biologist or resource specialist, who shall recommend appropriate provisions to prevent invasive plant species from colonizing in natural areas. These provisions may include the following: (1) review and screening of proposed plant palette and planting plans to identify and avoid the use of invasive species; (2) weed removal during the initial planting of landscaped areas; and (3) the monitoring for and removal of weeds and other invasive plant species as part of ongoing landscape maintenance activities. BIO-6: All street lighting shall be downcast luminaries or directional lighting with light patterns directed away from natural areas. 7.0 CUMULATIVE IMPACTS As discussed, the development of the project site would potentially result in impacts to biological resources if left unmitigated. The outlined mitigation measures would reduce those impacts to a less than significant level. There are no proposed developments in the immediate vicinity of the site. The only exception to this would be the proposed Masters College project situated to the east, which is currently being evaluated. However, the impacts from both the Masters College project and the Dockweiler Road extension that is the subject of this analysis have been previously evaluated as part of the City's General Plan. The extension of Dockweiler Road would not be growth inducing as this project is consistent with the City's General Plan for this area. Therefore, development associated with the proposed project and other development in the vicinity of the project site in the City Santa Clarita, would not result in a significant cumulative impact related to biological resources.

The road extension includes a bridge over Newhall Creek, a tributary of the Santa Clara River. The project is located in an un-numbered section of Township 4 North, Range 16 West, of the U.S. Geological Survey ("USGS") Newhall 7.5' quadrangle (Figure 1). Newhall Creek is at an elevation of about 1,264 feet above mean sea level at the bridge location. The Project will require notification to State and Federal agencies with jurisdiction over stream resources. However, the potential disturbance area for bridge construction is not known at this time. The purpose of this Delineation is to describe the limits of State and Federal jurisdiction within 200 feet upstream and downstream of the bridge location. 2 METHODS 2.1 Document Review Site -Specific Data. A desktop analysis of potential jurisdictional features was conducted for guidance in the field, based on the USGS topographic map of the project area and aerial photographs. Soil survey data available from the National Cooperative Soil Survey (USDA-NRCS) were not used because these data are not intended to be used at the fine scale of this project. Delineation Protoco/s. Documents consulted for delineation of Federal jurisdiction consisted of Lichvar and McColley (2008) regarding identification of "ordinary high water mark" in arid regions, the U.S. Army Corps of Engineers (USACE) guidelines for interpretation of Federal jurisdiction following the Rapanos, Carabell, and SWANCC decisions (USACE, 2007; USACE and EPA, 2007), the USACE 1987 Wetland Delineation Manual (Environmental Laboratory, 1987), and USACE guidelines and forms for jurisdictional determination in the arid southwest (USACE, 2001, 2008). Delineation of California State jurisdiction (CDFW and RWQCB) was based on definitions and regulations specified by Sections 1600-1616 of the Fish and Game Code, Title 14 of the California Code of Regulations, and Section 13050 of the California Water Code. Page 4 JD - Dockweiler Bridge 2.2 Field Survey A field survey of the site was conducted by Edith Read on .June 17, 2013. Site features were assessed for indicators of stream, riparian, or wetland functions. Indicators of stream functions, particularly surface flows, typically include a clearly defined bed and bank structure, bank shelving, deposits of organic debris, cracked mud or clay, and/or water marks on rocks or soil. Indicators of wetland functions typically include wetland or riparian vegetation, and/or soils with anaerobic, redoxymorphic, or hydric features. Plant taxonomy followed the current flora for California (Baldwin et al., 2012). Plant community designations for indigenous vegetation types were based on Sawyer et al. (2009). Determination of the wetland occurrence rating of plant species was based on the 2012 ratings for the Arid West Regional Supplement (USACE, 2012). 2.3 Delineation Criteria CDFW At the State level, the California Department of Fish and Wildlife (CDFW; formerly CDFG) has jurisdiction over rivers, streams, and lakes.] The California Code of Regulations defines a stream as "a body of water that flows at least periodically or intermittently through a bed or channel having banks and supports fish and other aquatic life including watercourses having a surface or sub surface flow that supports or has supported riparian vegetation."2 CDFW jurisdiction typically extends between the top of each bank or to the outer edge of contiguous riparian vegetation, whichever is greater. For this project, limits of CDFW jurisdiction within the potential work area were drawn to the tops of the levees on both sides of Newhall Creek. USA CE At the Federal level, the USACE regulates placement of "dredge" and "fill" in waters of the U.S. including adjacent wetlands under the authority of Section 404 of the Clean I Fish & Game Code §§ 1600 - 1616 2 California Code of Regulations (C.C.R.), Title 14 § 1.72 JD - Dockweiler Bridge Water Act.3 The Code of Federal Regulations defines "waters of the U.S." as intrastate lakes, rivers, streams, mudflats, sand flats, wetlands, sloughs, prairie potholes, wet meadows, playa lakes, or natural ponds. Wetlands are defined as "areas that are inundated or saturated by surface water or ground water at a frequency and duration sufficient to support, and that under normal circumstances do support, a prevalence of vegetation typically adapted for life in saturated soil conditions." Assessment of Federal jurisdiction is based on two main factors: 1) nexus or connectivity to "traditionally navigable waters" or "relatively permanent waters"; and 2) presence of "ordinary high water marks." RWQCB Federal authority over water quality under Section 401 of the Federal Clean Water Act is typically delegated to regional water quality control boards unless a project encompasses more than one region, in which case the State Water Resources Control Board may assert regulatory authority. The current Project falls under the authority of the Los Angeles Regional Water Quality Control Board. Section 401 of the Clean Water Act requires that "any applicant for a Federal permit for activities that involve a discharge to Waters of the U.S., shall provide the Federal permitting agency a certification from the State in which the discharge is proposed that states that the discharge will comply with the applicable provisions under the Federal Clean Water Act." In addition to Section 401 of the Federal Clean Water Act, the RWQCB exerts authority over "Waters of the State" and water quality by means of State law. "Waters of the State" are broadly defined by sections of the California Water Code, known as the Porter -Cologne Water Quality Control Act, as "any surface water or groundwater, including saline waters, within the boundaries of the state."4 As of this writing, the State Water Resources Control Board is considering adoption of a Wetland Area Protection Policy and regulations governing the discharge of dredge or fill material into waters of the State that would apply at State and regional levels 3 Clean Water Act of 1972 § 404. See also 33 U.S.C. § 1 341 4 California Water Code § 13050(e) Page 6 JD - Dockweiler Bridge (California State Water Resources Control Board, 2013). This policy is intended to improve consistency in the definition of a wetland and regulatory mechanisms affecting wetland protection, and an approach for collecting and tracking aquatic resource monitoring data. One difference between existing regulations and the new policy is in the definition of a wetland, wherein wetland vegetation does not have to be present for a feature to qualify as a wetland. Specifically, an area is defined as a wetland if, under normal circumstances: 1) the area has continuous or recurrent saturation of the upper substrate caused by groundwater, or shallow surface water, or both; 2) the duration of such saturation is sufficient to cause anaerobic conditions in the upper substrate; and 3) the area either lacks vegetation or the vegetation is dominated by hydrophytes. This definition is adopted here in anticipation of the new regulations. 3 RESULTS AND DISCUSSION Figure 2 shows topography of the region, and Figure 3 shows photographs representing the project site. Figure 4 shows vegetation and jurisdictional features in the survey area. 3.1 Watershed Connectivity, Geomorphology and Hydrology There are two jurisdictional features at the project location: 1 . Newhall Creek, upstream of its confluence with Placerita Creek and the south fork of the Santa Clara River. This creek is mapped by the USGS as a "blue -line" intermittent stream. The direction of creek flow is from southeast to northwest. Banks of the creek are nearly vertical, with the south bank containing artificial fill (pieces of concrete and asphalt). Railroad tracks and Railroad Avenue are to the west, beyond the top of the bank. Areas immediately east of the creek are vacant except for an industrial yard northeast of the proposed bridge location. No surface water was present during the .June survey, but sparse vegetation cover within the channel indicates frequent scour during the rainy season. Therefore this feature is best described as an intermittent riverine, relatively permanent water ("RPW") that has seasonal continuous flow and is tributary to the Santa Clara River, which flows into the Pacific Ocean, a traditionally navigable water ("TNW"). Vegetation and surface features indicate that seasonal JD - Dockweiler Bridge flows migrate across the entire width of the channel, which averages 35 feet in width at the base (Federal jurisdiction). The distance between the tops of the banks (limits of State jurisdiction) averages 100 feet. No indicators of prolonged water saturation or ponding, such as surface mud cracks, were observed during the survey. 2. Un-named ephemeral tributary to Newhall Creek. This narrow tributary is about 3.5 feet in width at its base (Federal jurisdiction) and is entirely within State jurisdiction over Newhall Creek. It is assumed that flow enters the project area from a culvert underneath the railroad tracks and Railroad Avenue - this could not be confirmed during the survey due to presence of a homeless camp at the presumed culvert location. The distinct bed and bank structure of this feature, and regional topography shown prior to extensive development in the area, indicate that it is more than just a gully resulting from localized erosion. Wetland indicators are absent from this feature. 3.2 Vegetation The following vegetation types occur within the survey area. Of these types, only the narrow -leaf willow thicket is a wetland indicator (Sa/ix exiqua - FACW). This vegetation is discussed in more detail below. Active Channel Vegetation is sparse within the active channel. The most common species are not wetland indicators. They include scalebroom (Lepidospartum squamatum -- FACU) and mulefat (Baccharis sa/icifo/ia - FAC). Narrow -Leaf Willow Thicket Narrow -leaf willows (Sa/ix exiqua - FACW) occur in a small stand (25 ft x 12 ft) within the alignment of the proposed bridge. While this species is a wetland indicator, other wetland indicators are absent. The vegetation occurs on the opposite side of Newhall Creek from the ephemeral tributary, and likely receives periodic dry -season runoff from streets to the west. We conclude that this thicket is probably not a jurisdictional JD - Dockweiler Bridge wetland at the Federal level, and is not a jurisdictional wetland at the State level. See Section 3.4 for additional discussion. Scrub Vegetation Scrub vegetation consists of scalebroom, mulefat, California sagebrush (Artemisia ca/ifornica -- NI), and buckwheat (Eriogonum fascicu/atum -- NI) in a range of densities on slopes above the active channel of Newhall Creek. None of these species are wetland indicators. Trap-, Three native trees occur adjacent to the northwest boundary of the survey area, about 200 feet northwest of the bridge location. Two of the trees are large California live oaks (Quercus agrifo/ia - NI) with trunk diameters ranging from four inches to two feet. The third tree is an elderberry (Sambucus nigra - FAC) and located under the oak canopy. Small groves of exotic trees (tentatively identified as locust - Robinia sp.) occur on the west side of Newhall Creek along the railroad right-of-way. 3.3 Soil Soil was evaluated at one location under the canopy of the narrow -leaf willow thicket. Figure 4 shows a photograph of the test pit. Below the litter, two stratified layers are visible, consisting of rock/cobble/sand in the first 12 inches, then six inches of sand down to the base of the pit. This sand layer changes in color, value, and chroma from light gray (5YR 7/1 ) to black (5YR 2.5/ 1) toward the bottom of the test profile. No odor was detected during sampling. While a few of the coarse fragments in the upper part of the profile had some faint orange streaks (5YR 5/8) indicative of reducing conditions, these features were not dominant. 3.4 Wetland Determination 3.4.7 Federal The hydrology and soils of the survey area (flood plains/gravel bars and sand) are naturally problematic for wetland delineation. The following paragraphs include Page 9 JD - Dockweiler Bridge excerpts (in italics) from the Arid West supplement (USACE 2008, page 98) of the wetland determination procedure for problematic sites where soils may meet the definition of a hydric soil but do not exhibit typical indicators. Our observations are described for each step of the procedure. 7. Verify that one or more indicators of hydrophytic vegetation are present or that the vegetation is disturbed or problematic. 7fso, proceed to step Z. Site observations: Narrow -leaf willow has an indicator ranking for the Arid West of Facultative Wetland. Therefore hydrophytic vegetation is present. Z. Verify that at least one primary or two secondary indicators of wet/and hydrology are present or that indicators are absent due to disturbance or other factors. 7f so, proceed to step 3. 7f indicators of hydrophytic vegetation and/or wet/and hydrology are absent, then the area is probably non -wetland and no furtherana/ysis is required. Site observations: no primary indicators of wetland hydrology are present. Only one secondary indicator of wetland hydrology (dominance of FACW vegetation) is present. Based on this information, and the observation that redoximorphic soil features are sparse and (where present) faintly expressed, we conclude that the willow thicket (300 square feet or 0.007 acre) is probably not a Federally jurisdictional wetland. Unfortunately, the Arid West procedure does not allow for a more definitive conclusion. 3.4. Z State According to the wetland definition under review at the State level, we conclude that the narrow -leaf willow thicket would not meet this definition. While narrow -leaf willow is a hydrophyte, there is no evidence of continuous or recurrent saturation of the upper substrate and no evidence of anaerobic conditions. 3.5 Non -Wetland Jurisdiction The proposed bridge will impact Newhall Creek, in a section of the creek that is classified as riverine and relatively permanent water, with continuous flow at least seasonally. The bridge may also impact a narrow, ephemeral tributary to Newhall Page 10 JD - Dockweiler Bridge Creek. The extent of permanent and temporary construction impacts need to be known in order to provide a more precise analysis of impacts. 4 RECOMMENDATIONS The narrow -leaf willow thicket, occupying 300 square feet (25 linear feet and 0.007 acre) within the bridge footprint, could not be definitely concluded to be a wetland using Federal jurisdictional delineation procedures. The only conclusions that could be reached are that the willow thicket is "probably" a non -wetland under Federal criteria, and is not a wetland under State criteria. Given the uncertainty at the Federal level, we recommend the following: 1 . Disclosure of the uncertain determination when applying for a permit under the Clean Water Act; and 2. If the bridge project is delayed for more than one year from the date of this report (i.e. beyond 2014), consider one or both of the following two actions: a) re-evaluate the wetland status of the willow thicket site in the field, using evaluation procedures for problematic sites specified in the Arid West manual (USACE 2008), with special focus on soils; and/or b) to avoid a possible permitting issue, assume the willows constitute a wetland and mitigate accordingly. 5 SOURCES CITED Baldwin, B.G., D.H.

If the aquatic resource Is a TNW, complete Section 11loA.1 and Section llloDol . only; If the aquatic resource Is a wetland adjacent to a TNW, complete Sections 11loA.1 and 2 and Section llloDol otherwise, see Section 111o13 below. 11�1►11�i�1 Summarize rationale supporting determination: 2. Wetland adjacent to TNW Summarize rationale supporting conclusion that wetland is "adjacent": B. CHARACTERISTICS OF TRIBUTARY (THAT IS NOT A TNW) AND ITS ADJACENT WETLANDS (IF ANY): This section summarizes information regarding characteristics of the tributary and its adjacent wetlands, if any, and it helps determine whether or not the standards for jurisdiction established under Rapanos have been met. The agencies will assert jurisdiction over non -navigable tributaries of TNWs where the tributaries are "relatively permanent waters" (RPWs), i.e. tributaries that typically flow year-round or have continuous flow at least seasonally (e.g., typically 3 months). A wetland that directly abuts an RPW is also jurisdictional. If the aquatic resource is not a TNW, but has year-round (perennial) flow, skip to Section III.D.2. If the aquatic resource is a wetland directly abutting a tributary with perennial flow, skip to Section III.D.4. 7 Supporting documentation is presented in Section III.F. 21 A wetland that is adjacent to but that does not directly abut an RPW requires a significant nexus evaluation. Corps districts and EPA regions will Include In the record any available Information that documents the existence of a significant nexus between a relatively permanent tributary that Is not perennial (and Its adjacent wetlands If any) and a traditional navigable water, even though a significant nexus finding Is not required as a matter of law. If the waterbodyg is not an RPW, or a wetland directly abutting an RPW, a JD will require additional data to determine if the waterbody has a significant nexus with a TNW. If the tributary has adjacent wetlands, the significant nexus evaluation must consider the tributary in combination with all of its adjacent wetlands. This significant nexus evaluation that combines, for analytical purposes, the tributary and all of its adjacent wetlands is used whether the review area identified in the JD request is the tributary, or its adjacent wetlands, or both. If the JD covers a tributary with adjacent wetlands, complete Section IILB.1 for the tributary, Section IILB.2 for any onsite wetlands, and Section III.B.3 for all wetlands adjacent to that tributary, both onsite and offsite. The determination whether a significant nexus exists is determined in Section III.0 below. 1.

Where there is a break in the OHWM that is unrelated to the waterbody's flow regime (e.g., flow over a rock outcrop or through a culvert), the agencies will look for indicators of flow above and below the break. 11Ibid. 24 (iv) Blologuca0 Characteristics.

(Y/N) Size (in acres) 26 Summarize overall biological, chemical and physical functions being performed: Co SIGNIFICANT NEXUS DETERMINATION A significant nexus analysis will assess the flow characteristics and functions of the tributary itself and the functions performed by any wetlands adjacent to the tributary to determine if they significantly affect the chemical, physical, and biological integrity of a TNW. For each of the following situations, a significant nexus exists if the tributary, in combination with all of its adjacent wetlands, has more than a speculative or insubstantial effect on the chemical, physical and/or biological integrity of a TNW. Considerations when evaluating significant nexus include, but are not limited to the volume, duration, and frequency of the flow of water in the tributary and its proximity to a TNW, and the functions performed by the tributary and all its adjacent wetlands. It is not appropriate to determine significant nexus based solely on any specific threshold of distance (e.g. between a tributary and its adjacent wetland or between a tributary and the TNMo Similarly, the fact an adjacent wetland lies within or outside of a floodplain is not solely determinative of significant nexus. Draw connections between the features documented and the effects on the TNW, as identified in the Rapanos Guidance and discussed in the lnstructional Guidebook. Factors to consider include, for example: • Does the tributary, in combination with its adjacent wetlands (if any), have the capacity to carry pollutants or flood waters to TNWs, or to reduce the amount of pollutants or flood waters reaching a TNW? • Does the tributary, in combination with its adjacent wetlands (if any), provide habitat and lifecycle support functions for fish and other species, such as feeding, nesting, spawning, or rearing young for species that are present in the TNW? • Does the tributary, in combination with its adjacent wetlands (if any), have the capacity to transfer nutrients and organic carbon that support downstream foodwebs? • Does the tributary, in combination with its adjacent wetlands (if any), have other relationships to the physical, chemical, or biological integrity of the TNW? Note: the above list of considerations is not inclusive and other functions observed or known to occur should be documented below: 1.

The search includes a review of all recorded archaeological sites within a 1/2-mile radius of the project site as well as a review of cultural resource reports on file. In addition, the California Points of Historical Interest (SPHI), the California Historical Landmarks (SHL), the California Register of Historical Resources (CAL REG), the National Register of Historic Places (NRHP), and the California State Historic Resources Inventory (HRI) listings were reviewed for the above referenced project site. The following is a discussion of the findings. Due to the sensitive nature of cultural resources, archaeological site locations are not released. Newhall, CA USGS 7,5-Qodrano% ARCHAEOLOGICAL RESOURCES: No archaeological sites have been identified on our maps within a 1/2-mile radius of the project site. No sites are located within the project site. This does not preclude the potential for archaeological sites to be identified during project activities. Two isolates (19-100340, 19-100503) have been identified within a 1/2-mile radius of the project site. No isolates are located within the project site. HISTORIC BUILT -ENVIRONMENT RESOURCES: Fourteen above -ground historic resources (19-180765, 19-187086, 19-187092, 19-188109, 19-188269, 19-188598, 19-188599, 19-188600, 19-188601, 19-188602, 19-188603, 19-188604, 19-188605, 19-188606) have been identified on our maps within a 1/2-mile radius of the project site. No above -ground historic resources are located within the project site. ADDITIONAL CULTURAL RESOURCE LISTINGS: The California Historic Resources Inventory (HRI) lists thirty-one properties that have been evaluated for historical significance within a 1/2-mile radius of the project site (see enclosed list). These are additional resources that are listed in the Historic Properties Data file and are located either within the project site or within the search radius. The California Point of Historical Interest (SPHI) of the Office of Historic Preservation, Department of Parks and Recreation, lists no properties within a 1/2-mile radius of the project site. The California Historical Landmarks (SHL) of the Office of Historic Preservation, Department of Parks and Recreation, lists no properties within a 1/2-mile radius of the project site. The California Register of Historical Resources (CAL REG) lists no properties within a 1/2-mile radius of the project site. These are properties determined to have a National Register of Historic Places Status of 1 or 2, a California Historical Landmark numbering 770 and higher, or a Point of Historical Interest listed after 1/1/1998. The National Register of Historic Places (NRHP) lists no properties within a 1/2-mile radius of the project site. HISTORIC MAP REVIEW Santa Susana, CA (1903 & 1941) 15' USGS - indicated that in 1903, there was a significant amount of development within the project site. The project site was located within a dense urban environment with numerous roads and buildings present. The Southern Pacific Railroad (San Francisco & New Orleans Line) and Newhall Creek both ran through the project site. Placerita Creek ran to the north of the project site and historic place names nearby included Newhall and Elayton. In 1941, the project site was still located within a dense urban environment with several roads and buildings present in the project site. There was one school present within the vicinity of the project area and all other previously mentioned features still remained. PREVIOUS CULTURAL RESOURCES INVESTIGATIONS: Twenty-four studies (LA274, LA834, LA852, LA856, LA984, LA1153, LA3289*, LA3644, LA3661, LA3690*, LA3731*, LA5844*, LA6860, LA7167, LA8129, LA8255*, LA8785, LA8958*, LA9422, LA9867*, LA10405, LA10642*, LA11985, LA12200) have been conducted within a 1/2-mile radius of the project site. Of these, eight are located within the project site. There are eleven additional investigations located on the Newhall, CA 7.5' USGS Quadrangle that are potentially within a 1/2-mile radius of the project site. The reports are not mapped due to insufficient locational information. (* = Located within the project site) RECOMMENDATIONS Significant portions of the project site have not been previously surveyed for archaeological resources. Therefore it is recommended that a Phase -I archaeological survey be conducted in areas unobstructed by urban development within the project footprint and area of potential effect. It is also recommended that any previously unidentified historic properties (45 years and older) be recorded, and evaluated for local, state, or national significance prior to the approval of project plans. Finally, the Native American Heritage Commission should be consulted to identify if any additional traditional cultural properties or other sacred sites are known to be in the area. The professional consultant you retain may request the records search map, archaeological site records, and bibliography from the Information Center referencing the SCCIC number listed above for a fee (per the fee schedule). For your convenience, you may find a professional consultant* at www.chrisinfo.ora. Any resulting reports by the qualified consultant should be submitted to the South Central Coastal Information Center as soon as possible. *The SCCIC does not endorse any particular consultant and makes no claims about the qualifications of any person listed.

We do not have any fossil vertebrate localities that lie directly within the boundaries of the proposed project area, but we do have localities nearby from the same sedimentary deposits that occur within the proposed project area. Surficial deposits in most of the proposed project area, the less elevated portion, consist of younger Quaternary gravels or sands associated with the Newhall Creek that borders on the south and west and the Placerita Creek that flows through the northern part of the proposed project area. Both of these drainages flow into the Santa Clara River just to the northwest of the proposed project area. These deposits usually do not contain significant vertebrate fossils, at least in the uppermost layers. In the more elevated terrain in the southeastern portion of the proposed project area, however, there are dissected older Quaternary fluvial and fan deposits as well as exposures of the terrestrial Pliocene Saugus Formation. These deposits may also occur at depth in the proposed project area. We have no fossil vertebrate localities nearby from the younger Quaternary alluvial deposits. Our closest vertebrate fossil localities from the Saugus Inspiring wonder, discovery and responsibility for our natural and cultural worlds. Formation, or possibly the older Quaternary sediments, are LACM 6803-6804, directly north of the proposed project area in Saugus south of Bouquet junction on the east side of Bouquet Canyon Road, that produced fossil specimens of camel, Camelidae, and horse, Equus. Shallow excavations in the younger Quaternary alluvial deposits found at the surface in the less elevated portions of the proposed project area probably will not encounter significant fossil vertebrate remains. Deeper excavations that extend down into older Quaternary deposits or any excavation in the Saugus Formation, however, may well uncover significant vertebrate fossils. Any substantial excavations in the proposed project area, therefore, should be monitored closely to quickly and professionally recover any fossil remains while not impeding development. Any fossils recovered during mitigation should be deposited in an accredited and permanent scientific institution for the benefit of current and future generations. This records search covers only the vertebrate paleontology records of the Natural History Museum of Los Angeles County. It is not intended to be a thorough paleontological survey of the proposed project area covering other institutional records, a literature survey, or any potential on -site survey.

The proposed road alignments are located on the alluvial flood plain and hillside areas adjacent to Newhall Creek. The majority of the proposed road alignment for Lyons Avenue traverses undeveloped land, except for areas where artificial fill and railroad ballast have been placed to elevate and support the existing railroad double tracks. Dumped fill with abundant blocks of asphalt and concrete and other miscellaneous debris has been placed on the southwest bank of Newhall Creek, just northeast of the proposed at -grade railroad crossing. The proposed road alignment of Dockweiler Drive also traverses undeveloped land and a storage yard utilized by Los Angeles County Department of Public Works. The site is covered with light to moderate growth of natural grasses and chaparral. Details of the site topography are shown on the base map used for the Geologic Map (see Plate I). Elevations at the site range from approximately 1255 to 1370 ft above mean sea level. Allan E. Seward Engineering Geology, Inc. Geology and Geotechnology Hall and Foreman, Inc. Job No: 14-2393 October 17, 2014 Page 4 4.0 GEOLOGIC AND GEOTECHNICAL CONDITIONS 4.1 Geologic Setting The site is located within the central part of the Transverse Ranges geomorphic province of southern California, in the eastern portion of the Ventura Basin. The Ventura Basin has been tectonically down -warped in the geologic past to produce a large-scale synclinal structure in which a thick sequence of Cenozoic sediments has accumulated. In the vicinity of the proposed road alignments, much of the hillside area along the northeastern margin of Newhall Creek consists of bedrock of the Quaternary -age Pacoima Formation (Qp). The relatively flat flood plain southwest of Newhall Creek is underlain by sub - horizontal alluvium deposited (Qal). The Pacoima Formation and alluvial deposits are underlain by bedrock of the Plio-Pleistocene, nonmarine Saugus Formation (TQs). No faults or folds have been identified at the project site on the referenced published geologic map of the area. A Geologic Overview Map (see Figure 2) based on Geologic Map of the Newhall Quadrangle (Dibblee, 1996) is provided at the end of this report. 4.2 Geologic Structure The natural slopes at the project site are underlain by sub -horizontally bedded Pacoima Formation in erosional unconformable contact over Plio-Pleistocene non -marine sediments of the Saugus Formation. The Saugus Formation in the vicinity of the subject site generally strikes roughly east to west and dips gently to the north (Treiman, 1987; and Dibble, 1996). The Saugus Formation bedding measured in northern bank of the Newhall Creek strikes N70W and dips 5° north. The measured bedding is generally consistent with regional geologic maps and the geologic structure as documented during a previous investigation and published report (see references). 4.3 Geologic Units The Geologic Map (see Plate I) enclosed in the Appendix of this report illustrates the approximate limits of exposed geologic units based on field observations and the referenced published geologic maps. Artificial fill and railroad ballast have been placed below the railroad tracks. Pavement and aggregate base have been placed beneath existing roadways. General descriptions of geologic units provided below are based the prior geologic observation in the vicinity of the project site, and the exposures in the banks of Newhall Creek in the vicinity of the proposed box culvert. Allan E. Seward Engineering Geology, Inc. Geology and Geotechnology Hall and Foreman, Inc. Job No: 14-2393 October 17, 2014 Page 5 4.3.1 Saugus Formation (TQs) Bedrock of the Plio-Pleistocene-age Saugus Formation (TQs) is exposed along the lower portion of the northerly eroded bank of Newhall Creek, just east of the proposed road alignment. The Saugus Formation sediments consist dominantly of gray to light brown sandstone and conglomeratic sandstone with scattered greenish -gray siltstone and silty sandstone (Treiman, 1987). Bedding within the Saugus Formation varies from predominately massive and indistinct to cross -bedded to locally well -developed planes on lensing, fine-grained units. Local variance in bedding orientations is common and is due to cross bedding and/or channelized (erosional) contacts. 4.3.2 Pacoima Formation (Qp) Bedrock of the Quaternary -age Pacoima Formation (Qp) mantles the majority of the hillside area along the northern margin of Newhall Creek. This formation has been designated as "Older Dissected Surficial Sediments or Qog" after Dibblee, 1996; however, these terrace deposits have been assigned to the Pacoima Formation (of Oakeshott, 1958) by Treiman (CDMG, 1987). For this report, the nomenclature by Treiman is used. The bedrock generally consists of lensing, crudely stratified, light yellowish -brown to yellowish -brown to brown, silty to clayey, fine- to coarse -grained sandstone with some gravel, cobbles and rare boulders. Bedding is generally crude to locally well defined. Generally the bedrock is concealed by a mantling of soil and colluvium. However, the eroded banks of the Newhall Creek expose unweathered bedrock. 4.3.3 Quaternary Alluvium (Qal) Quaternary Alluvium (Qal) underlies the existing surficial artificial fill materials located westerly of Newhall Creek south of 121h Street, and easterly of Newhall Creek north of 12th Street. Based on data obtained by this firm for the adjacent Old Town Newhall Library site, the alluvium is anticipated to consist of interbedded layers of poorly graded sand, silty sand, and gravelly sand. Interbedded layers of sandy silts and clays may also be present. These materials are typically medium dense to dense in the upper 30 to 40 ft. with locally loose conditions in the upper 10 ft. 4.3.4 Recent Stream Channel Deposits (Qsc) Quaternary Stream channel deposits (Qsc) are located within the active Newhall Creek channel. These deposits consist of recent alluvium that has been reworked due to heavy runoff during periodic rains. Stream channel deposits are very similar to the Quaternary alluvium and generally consist of silty sands, sands, and gravels with cobbles. Allan E. Seward Engineering Geology, Inc. Geology and Geotechnology Hall and Foreman, Inc. Job No: 14-2393 October 17, 2014 Page 6 4.3.5 Quaternary Colluvium (Qc) Colluvium (Qc) is a non -bedded, heterogeneous accumulation of soil and weathered bedrock deposited by gravity on all but the steepest slopes. These deposits have been mapped based on review of the topography where the estimated thickness is greater than about 3 feet. 4.3.6 Artificial Fill (af) Artificial fill (af) was apparently placed below the existing railroad tracks to elevate the tracks above the Newhall Creek Flood Plain. The engineering characteristics of this material are currently unknown. 4.3.7 Dumped Fill (df) Dumped fill (df) is present along the active stream margins of Newhall Creek at the vicinity of the proposed Lyons Avenue road alignment. The dumped fill consists of fill soils with abundant debris (asphalt, concrete, construction trash, metal, vehicle tires). Also present near the proposed alignment is an abandoned vehicle that is partially buried. 4.3.8 Railroad Ballast Railroad ballast consisting of crushed natural rock was placed to support and elevate the two sets of railroad tracks at the site. 4.4 Landslides Review of the referenced published geologic maps indicates that no landslides have been mapped at or adjacent to the site. Review of aerial photographs lack geomorphic features that would indicate prior landslide movement. 4.5 Ground Water Review of historic ground water data from the Seismic Hazard Map for the Newhall Quadrangle, Water -Resources Investigation using Analog Model Techniques in the Saugus -Newhall Area (Robson, 1972), and Los Angeles Flood Control District (LACFCD) water well records indicates that historic high ground water levels are between 75 and 100 ft. below the existing surface at the project site. The locations of nearby water wells are shown on the Water Well Location Map (see Figure 2) and the historic ground water levels for each well obtained from LACFCD records are provided in Summary of LAFCD Water Well Data (see Table 1). In addition, ground water was not encountered in subsurface explorations performed by this firm to a depth of 50 ft in the alluvium for the adjacent Old Town Newhall Library. However, temporary perched ground water Allan E. Seward Engineering Geology, Inc. Geology and Geotechnology Hall and Foreman, Inc. October 17, 2014 Job No: 14-2393 Page 7 conditions may exist below Newhall Creek following periods of significant rainfall and runoff. A low potential exists for temporary, perched ground water conditions to develop within the bedrock of the Pacoima formation. Perched ground water can contribute to slope instability in natural slopes and cut slopes. To prevent build-up of water, subdrains are typically recommended in canyon areas in which fill will be placed and back drains for slopes that are to be constructed as Stability Fills or Buttress Fills. Due to the historic high ground water elevations and the elevated nature of portions of the road alignment, ground water is not expected to significantly affect the project, provided the proposed grading is evaluated from a geotechnical standpoint during the design stage and the geotechnical recommendations are implemented during construction. 5.0 POTENTIAL CONSTRAINTS, IMPACTS, AND MITIGATION OPTIONS 5.1 Seismic Considerations 5.1.1 Introduction The subject site lies within the seismically active southern California region. Earthquake -related hazards typically include ground rupture, ground shaking, and ground failure. 5.1.2 Ground Rupture Review of the Alquist-Priolo Earthquake Fault Zone Map for the Newhall Quadrangle, the Seismic Safety Element of the L.A. County General Plan, and the published Geologic Maps referenced at the end of this report indicates that no active or potentially active faults traverse the project site. Review of the site topography and the aerial photographs listed at the beginning of this report did not reveal any lineaments or other indicators suggestive of faulting at the site. The nearest known active fault is the San Gabriel Fault, which is 3.7 km from the site at its nearest point (see Table 2 for a list of regional faults near the site and Figure 3 for a map of the fault locations). Therefore, the probability of fault -related ground rupture at the site is considered to be very low. 5.1.3 Ground Motion Peak ground acceleration (PGA) consistent with maximum considered earthquake (MCE) ground motions were evaluated at the site for bedrock (Site Class B) and alluvial (Site Class C) soil conditions in accordance with the 2013 California Building Code and ASCE 7-10. The mapped MCE geometric mean (MCEG) peak ground accelerations Allan E. Seward Engineering Geology, Inc. Geology and Geotechnology Hall and Foreman, Inc. October 17, 2014 Job No: 14-2393 Page 8 (PGAM) adjusted for Site Class effects were first evaluated using the U.S. Seismic Design Maps web tool provided by the United States Geological Survey (USGS). The MCEG PGAM was then evaluated for a 2 percent probability of exceedance within a 50- year period using the USGS 2008 Interactive Deaggregation web tool. The PGAM calculated using the probabilistic procedure is based on estimated values of shear wave velocity (VOO) within the range designated for the corresponding Site Class. The estimated PGAM for bedrock (1.10g) and alluvial (1.03g) soil conditions was taken as the lesser of the mapped geometric mean peak ground accelerations and the probabilistic geometric mean peak ground accelerations indicated in the table below. Geologic Unit Site Class Estimated shear wave velocity, V,30 (m/s) MCEG PGAM Mapped Probabilistic Bedrock C 455 1.10g 1.17g Alluvium D 270 1.10g 1.03g 5.1.4 Ground Failure Ground failure is a general term for seismically induced, secondary, permanent ground deformation caused by strong ground motion. This includes liquefaction, lateral spreading, ground lurching, seismic settlement of poorly consolidated materials (dynamic densification), differential materials response, sympathetic movement on weak bedding planes or non -causative faults, slope failures, and shattered ridge effects. The majority of the project site is underlain by bedrock materials that are not susceptible to liquefaction. The alluvial soils present the site (see Geologic Map, Plate I) are not designated on the State of California Seismic Hazard Zone Map for the Newhall Quadrangle as a zone in which investigation of potentially liquefiable materials is required. The depth to historic high ground water at the site is greater than 50 ft. Based on the preceding factors, the potential for liquefaction and associated seismic settlements and lateral spreading is therefore considered very low. Relatively loose granular alluvial soils located within and adjacent to the active Newhall Creek channel and within minor tributary canyons adjacent to the road alignment may be prone to dynamic densification as a result of future earthquake shaking. Evaluation of the potential for dynamic densification should be performed at the design stage. Typically the potential for dynamic densification of these materials can be mitigated by removal of the materials and then replacing them as compacted fill. Potential for seismic settlement (dynamic densification) is negligible in the bedrock portions of the site. Allan E. Seward Engineering Geology, Inc. Geology and Geotechnology Hall and Foreman, Inc. October 17, 2014 Job No: 14-2393 Page 9 The hillside areas directly adjacent to the road alignment are designated on the State of California Seismic Hazard Zone Map for the Newhall Quadrangle as a zone in which investigation of potential for earthquake -induced landslides is required (see Figure 4). The potential for earthquake -induced slope failures and surficial failures on the critical natural and proposed design slopes will need to be evaluated at the design stage and, if necessary, provide mitigation measures. Cut and fill slopes constructed per the California Building Code typically are not subject to earthquake -induced failures. Typical mitigation for slopes prone to earthquake -induced failures include avoidance, removal of surficially unstable materials, laying back the slope to a shallower gradient, buttressing, construction of shear keyways, or debris basins and walls that may be designed to divert and/or collect the calculated volume of material expected to fail. Additionally, no landslides have been mapped at the project site. Due to the relatively shallow dip of the bedding of the Pacoima Formation and the Saugus Formation bedrock, and of the flat -lying alluvial deposits that underlie the site, the potential for differential materials response and slippage along weak bedding planes is considered to be negligible. 5.2 Slope Stability Proposed slopes, future grades, and existing grades are not shown on the current project plans. It is anticipated that both cut and fill slopes will be necessary at various locations along the proposed alignments and that cut slopes will expose Saugus Formation and Pacoima Formation bedrock. These proposed slopes should be designed and constructed at gradients of 2:1 horizontal to vertical or shallower. All constructed slopes should be evaluated by a geotechnical firm for conformance to applicable requirements/standards for gross and surficial slope stability. If it is determined that proposed slopes do not satisfy required factor of safety requirements for gross slope stability, mitigation measures will have to be designed based on results of slope stability analyses. If surficial stability of the proposed slopes is determined to be insufficient, measures to mitigate surficial stability will be required. This may include but not be limited to the following: 1. Avoidance. 2. Stability fills. 3. Flattening of slopes to 3:1 (h:v), or flatter. 4. Seeding/planting of slopes. 5. Guniting of slopes. 6. Mechanically Stabilized Earth (MSE) slopes. Natural slopes adjacent to the proposed road alignments exposing adverse geologic Allan E. Seward Engineering Geology, Inc. Geology and Geotechnology Hall and Foreman, Inc. October 17, 2014 Job No: 14-2393 Page 10 bedding conditions or steep gradients should be evaluated. If it is determined that these slopes do not satisfy required factor of safety requirements the natural slopes may be stabilized with Buttress Fills or Shear Keys designed by the Project Geotechnical Engineer. Laboratory testing of fill source materials is required to evaluate both gross and surficial stability of the proposed fill slopes, including remedial Buttress Fills and Stability Fills. Shear strength testing should be performed on soil samples that represent the mixture of materials that will be placed in the proposed fills. Steep natural slopes adjacent to the proposed road alignment should also be evaluated for potential debris flow hazards. Avoidance of the hazard by selective structural locations, construction of impact or debris walls and/or debris basins, control of run-off or removal of loose surficial materials can be used to mitigate debris flow hazards. 5.3 Deep Fills Based on preliminary review of the proposed road alignments, deep fill areas (i.e. fills deeper than 40 ft below proposed grade) are not anticipated. 5.4 Soil Compressibility Rapidly buried, unsaturated sediments, such as colluvium and alluvium, commonly contain extensive voids and, as a consequence, are subject to hydro -compression (collapse) settlement when inundated. Hydro -compression occurs when water enters sediments and reorients the sediment particles into a more compact arrangement with fewer and smaller voids. Compacted fills and structures constructed over deposits prone to hydro - compression may experience settlement and associated distress and damage. Based on explorations for the adjacent Old Town Newhall Library site, alluvial soils at the project site are anticipated to be typically medium dense to depths of 30 to 40 ft, with local loose zones in the upper 10 ft. The density of the artificial fill placed below the railroad tracks is currently undefined. The potential for settlement within these units should be addressed in more detail during a future geotechnical investigation at the design stage. If soils subject to hydro -compression or consolidation are identified at the site, settlement and potential adverse impacts to the proposed road improvements can be mitigated by removal and recompaction of loose or soft material. The phenomenon of hydro -compression does not apply to the bedrock deposits that underlie most of the site. Further exploration should be performed at the site to evaluate if hydro -compression -prone materials, such as colluvium, are present in areas where pavements or compacted fills are proposed. Allan E. Seward Engineering Geology, Inc. Geology and Geotechnology Hall and Foreman, Inc. Job No: 14-2393 October 17, 2014 Page 11 5.5 Erosion Potential and Drainage Fill, bedrock, and soil materials at the site will be susceptible to erosion if drainage features to control sheet flow over the ground surface are not provided. The drainage features should be designed to prevent water from ponding on graded areas and from flowing over natural or constructed slopes, and should direct surface water to designed debris basins or natural drainage courses, where applicable. Debris material generated by erosion of site materials should be contained inside the site boundaries. The potential for erosion of the banks of Newhall Creek should be evaluated by the project civil engineer. 5.6 Dam Inundation and Flooding No dams currently exist in the Newhall Creek Drainage and the site is not in a dam inundation area per the Flood and Inundation Hazard Map (Plate 6) of the Los Angeles County Safety Element of the General Plan. The potential for dam inundation is therefore considered nonexistent. The potential for flooding of Newhall Creek should be evaluated by the project Civil Engineer. 5.7 Construction Considerations 5.7.1 Rippability The site is underlain by Saugus Formation, Pacoima Formation, Quaternary alluvium and artificial fill. These materials can be ripped with standard grading equipment. 5.7.2 Oversized Material The alluvial and bedrock materials underlying the site may contain significant quantities of oversized material. Additionally, the dumped fill located along the southwest bank of Newhall Creek contains common blocks of asphalt and concrete as well as scattered boulders, car parts, and other oversized debris. Any oversized material that may be encountered during construction should not be incorporated into potential compacted fill during grading operations. Specifications and guidelines for handling and disposal should be addressed by the project geotechnical engineer at the design stage. 5.7.3 Expansion Potential of Soils The site alluvial materials are generally granular and are not typically expansive in nature. However, fine-grained units of the Saugus Formation are known to have significant expansion potential when exposed to water. In addition, Pacoima formation bedrock, artificial fill, colluvium and alluvial deposits present at the site may contain Allan E. Seward Engineering Geology, Inc. Geology and Geotechnology Hall and Foreman, Inc. October 17, 2014 Job No: 14-2393 Page 12 material with significant expansion potential. Expansive materials at the site should be evaluated by the Project Geotechnical Engineer during the grading plan stage of development. Expansion potential of site soils can be mitigated by controlling the water content and density of fill soils, by specifying embedment and reinforcement of structures, and by removing the expansive materials and replacing them with compacted material with low expansion potential. 5.7.4 Soil Corrosivity Past experience with similar soils on nearby sites suggests that the on -site soils likely have a low concentration of sulfate and chloride, and low acidity. This indicates a low potential for corrosion of concrete and, therefore, it is anticipated that Type I or 11 Portland cement will be satisfactory for use at the site. The resistivity of similar soils near the site tested by this firm indicates that they are typically moderately corrosive to ferrous metals. The corrosive characteristics of the site soils should be verified with laboratory testing at the design stage. If corrosive soils are encountered, options to mitigate potential corrosive soils include protective wraps and coatings for buried metal pipes and special types of cement that are resistant to corrosion. 5.7.5 Shrinkage and Bulking of Materials Typically, soil, colluvium, uncompacted artificial fill, alluvial deposits, and terrace deposits (i.e. Pacoima formation bedrock) reduce in volume ("shrink") by up to about 10 percent when excavated and subsequently recompacted. In contrast, Saugus Formation bedrock typically increases in volume ("bulk") by up to about 5 percent when excavated and recompacted. In order to evaluate the cut -fill balance of the proposed grading, shrinkage/bulking of on -site materials including landslide debris should be estimated at the design stage. 5.8 Retaining Walls The grades at the northeast end of Lyons Avenue and adjacent portions of Railroad Avenue will need to be raised in order to tie into the existing grade at the railroad crossing. It is our understanding that retaining walls may be used to accommodate the changes from the proposed grades to adjacent properties proposed to remain at existing grades. Geotechnical parameters for these walls and for design of the proposed box culvert and associated wing walls for the Newhall Creek crossing should be addressed at the design stage. 5.9 Oil Wells and Water Wells Review of the Munger Map Book and California Division of Oil and Gas records indicates Allan E. Seward Engineering Geology, Inc. Geology and Geotechnology Hall and Foreman, Inc. October 17, 2014 Job No: 14-2393 Page 13 that no oil wells have been drilled on or immediately adjacent to the site. If any undocumented oil wells are encountered during future construction operations at the site, their location(s) should be surveyed and the current well conditions evaluated. Review of LACFCD records indicates that water wells have been drilled in the vicinity of the proposed road alignments (see Water Well Location Map, Figure 2). If one of these water well is within the proposed road alignment, or if a water well is encountered during future construction operations at the site, the location should be surveyed and the potential impacts to well conditions should be evaluated. 6.0 PROJECT FEASIBILITY The proposed development is feasible from a geologic and geotechnical standpoint and will be safe from geologic hazards provided that the geologic and geotechnical recommendations outlined in this report, along with appropriate building and grading codes, are taken into account during the planning, design and construction phases of the project. 7.0 CONCLUSIONS AND RECOMMENDATIONS The following conclusions and recommendations summarize the primary geologic and geotechnical issues that may impact the proposed development: 1. Potential for primary ground rupture on a fault at the site is considered to be low. 2. Peak ground acceleration (PGA) consistent with maximum considered earthquake (MCE) ground motions is expected to be 1.03g in alluvial portions of the site (and 1.10g in portions of the site where bedrock outcrops or is present at shallow depth. 3. The alluvium that underlies portions of the site is not designated as potentially liquefiable on the State of California Seismic Hazard Zone Map for the Newhall Quadrangle. In addition, historic high ground water elevations are greater than 50 ft in depth. Therefore the potential for liquefaction of alluvium is considered very low. 4. The potential for seismic settlement (dynamic densification) during future seismic events is non-existent in the bedrock portions for the site but should be evaluated in site alluvial soils, colluvium, and existing artificial fills to remain in place. 5. All slopes should be evaluated by the Project Geotechnical Engineer at the planning and design stages. The hillside area of the site is designated on the State of California Seismic Hazard Zone Map to have earthquake -induced slope instability. However, the potential for earthquake -induced slope failures is considered low provided that future Allan E. Seward Engineering Geology, Inc. Geology and Geotechnology Hall and Foreman, Inc. October 17, 2014 Job No: 14-2393 Page 14 geologic and geotechnical evaluations and recommendations for slope stability are incorporated into design and construction. 6. No landslides have been mapped on the subject site. 7. Stability of cut slopes that are constructed at gradients of 2:1 or shallower are anticipated to expose favorable bedding conditions and be grossly stable. However, cut slopes will require subsurface investigation to determine the specific geologic conditions for evaluation by the Geotechnical Engineer. Remedial measures will be required where ascending or descending cut slopes are not stable as determined by geologic or geotechnical stability analyses. 8. A study should be conducted at the design stage to confirm the geologic conditions of natural slopes. This study should include subsurface investigation to determine the specific geologic conditions for evaluation by the Geotechnical Engineer. Remedial measures will be required where ascending or descending slopes are not stable as determined by geologic or geotechnical stability analyses. 9. A study should be conducted at the design stage to evaluate potential debris flow hazards on steep natural slopes ascending from the proposed road alignments. Avoidance of the hazard by selective structural locations, construction of impact or debris walls and/or debris basins, control of run-off or removal of loose surficial materials can be used to mitigate debris flow hazards. 10. Rapidly buried silty sediments such as thick colluvium and alluvium may be subject to hydro -compression. A study should be conducted to evaluate the hydro -compression potential of colluvial deposits and portions of the alluvium. Materials characterized as susceptible to hydro -compression tests in the laboratory can be mitigated by removal prior to the placement of fill. Specific recommendations should be provided at the design stage. 11. The bedrock is moderately consolidated, which indicates that grading operations can be performed with conventional equipment. 12. Cobbles and small boulders are likely present within the alluvium and bedrock. This oversize material may present difficulties during cutting operations with some types of equipment. In addition, oversize material will require special handling during fill construction. 13. A study should be conducted to evaluate the expansive potential of fine-grained soils during the design stage. If potentially expansive units are encountered in the street grades during construction, they should be evaluated by Expansion Index (EI) tests by Allan E. Seward Engineering Geology, Inc. Geology and Geotechnology Hall and Foreman, Inc. October 17, 2014 Job No: 14-2393 Page 15 the Project Geotechnical Engineer relative to mitigations. The expansive material can be removed to a specified depth determined by the Project Geotechnical Engineer and replaced with soil with very low to non -expansive characteristics. Alternatively, the expansive soil may be treated with additives to lower the expansion potential. 14. Soils on site may be corrosive to concrete and ferrous metals. Soil moisture, chemistry, and other physical characteristics all have important effects on corrosivity. Testing during development will indicate what special measures, such as cement type in concrete and corrosion protection for metallic pipes, may be required for construction. 15. Planting and irrigation of cut slopes and fill slopes should be included in future design phases in order to improve surficial stability of slopes and to mitigate potential for erosion. 8.0 LIMITATIONS This report has been prepared by Allan E. Seward Engineering Geology, Inc. for the exclusive use of the City of Santa Clarita and its design consultants for the specific site discussed herein. This report should not be considered transferable. Prior to use by others, this firm must be notified, as additional work may be required to update this report. In the event that any modification in the location or design of the proposed development is planned, the conclusions and recommendations contained in this report will require a written review by this firm with respect to the planned modifications. The proposed development is located in southern California, a geologically and tectonically active region, where large magnitude, potentially destructive earthquakes are common. Therefore, ground motions from moderate or large magnitude earthquakes could affect the project site during the design life of the project. The current standards for construction provided in the California Building Code are designed to safeguard against major failures and loss of life, but are not intended to prevent damage, maintain function or provide for easy repair. Conformance to code standards does not constitute any kind of guarantee or assurance that significant structural damage will not occur in the event of a maximum level of earthquake ground motion. However, it is reasonable to expect that a well -planned and constructed structure will not collapse in a major earthquake and that protection of life will be reasonably provided, but not with complete assurance. Typically, faulting is confined to the area adjacent to a known fault. However, absolute assurance against future fault displacement in other areas is not possible in tectonically active regions because new faults can form over time and long inactive (pre -Holocene) faults may be reactivated in response to evolving tectonic stresses and geologic conditions in the earth's Allan E.

Therefore, the timing, location and magnitude of new ground surface ruptures during a seismic event cannot be known with certainty. In performing these professional services, this firm has used the degree of care and skill ordinarily exercised under similar circumstances by reputable geologists and geotechnical engineers practicing in this or similar localities. It should be recognized that subsurface conditions can vary in time, and laterally, and with depth at a given site. Therefore, our conclusions and recommendations are professional opinions and are not meant to be a control of nature. We make no other warranty either expressed or implied. Allan E.

It is our hope that the contents of this application are sufficient for an expedient review and approval process. This drainage concept study evaluates the hydraulic and scour impacts of the proposed box culvert in Newhall Creek and documents on -site and off -site hydrology and drainage patterns. This report summarizes findings and proposed channel improvements and modifications including recommended scour countermeasures. Rivertech performed a scour analysis at the future Dockweiler Road Bridge to determine the scour potential per the methodology accepted by the County of Los Angeles. Provided in this study are the hydraulic conceptual design to evaluate the need for potential countermeasures for scour protection. The Location of the site is shown on Figure 1. Figure 1. Site Location Map. INTRODUCTION/PURPOSE OF STUDY The purpose of this study is to evaluate the future extension of Dockweiler Road and conceptually the planned Dockweiler Road Bridge, which will connect to Lyons Avenue, over Newhall Creek. This hydraulic and scour study associated with the proposed Dockweiler Road and Lyons Avenue extension is focusing on following tasks: Hydraukc and Scour Study, Newhall Creek at Proposed Dockweiler Road Extension, Santa Clarita, California • To determine the scour and channel stability characteristics, perform hydraulic analysis applying the Capital Flood and Flood Insurance Study (FIS) flows of the Newhall Creek Channel between Master College and existing 15t' Street bridge. • To determinate the existing and post -project scour potential with implementation the proposed bridge over Newhall Creek Channel To recommend Newhall Channel countermeasure that will provide more channel stability and mitigate the scour potential. LITERATURE REVIEW Rivertech reviewed and implemented all the relevant information and data, specifically but not limited to the site plans, design plans and prior reports and studies. TECHNICAL APPROACH The basis for this hydraulic and scour study is the existing technical data and field reconnaissance. Existing technical data such as record plans, available hydrology data and flood studies, floodplain maps and topographic data were reviewed for relevance and applicability for this study of the proposed site. Data sources included the LACFCD, FEMA and the US Army Corps of Engineers. Hydrology Data The hydraulic, sedimentation and scour analyses require both steady-state and unsteady flow. For the one-dimensional hydraulic and scour analyses, peak flows are needed as input data. Peak Flow One of the sources of hydrologic data is the Los Angeles County Flood Control District (LACFCD) Design Division who provided hydrologic data for Newhall Creek Channel, which was part of 2001 to 2005 LACFCD comprehensive study for the South Fork of the Santa Clara River watershed. Peak flows for Newhall Creek sub -areas are provided for 50-year clear -flow, 50-year burned -flow and 50-year burned/bulked (Capital Flood). The second source of hydrologic data is the Federal Emergency Management Agency, as part of the Flood Insurance Study, which provides 100-year peak flows. Table 1.

Hydraukc and Scour Study, Newhall Creek at Proposed Dockweiler Road Extension, Santa Clarita, California Reviewing the drainage information associated with Newhall Creek Channel as provided in these studies, the LACFCD public works policy of flood protection, and the drainage policy for Santa Clara River per Section 2.2 of the LACFCD Sedimentation Manual it can be concluded that the Newhall creek channel shall be designed based on the Capital flood rates (50-year rainfall, burned and bulked) and channel section of soft bottom with protective levee. These design requirements are consistent with the existing flood control improvements per LACFCD as -built plans "Newhall Creek unit IA" and Storm Drain Plans in Tract No.32365. Unsteady Flow The sediment transport modeling requires time -varied flow as the upstream boundary condition. The hydrologic data, which was furnished by the aforementioned sources, is for steady-state conditions. Although there are no streamflow gages along Newhall Creek and one abandoned short-term gage along the South Fork of the Santa Clara River, there are a few gages in the Santa Clara River watershed that exhibit similar hydrologic characteristics to Newhall Creek. The USGS streamflow gages that are meet the minimum record length (10 years) criterion and are located in the same hydrologically region, are: Santa Clara River Near Saugus, CA (11108000), Santa Clara River Ab Rr Station Near Lang, CA (107745) and Bouquet Canyon Near Saugus, CA (11107860). The annual peak flows were determined from each of the gage records and used as input to a Log Pearson Type III streamflow gage analysis.4 The peak flows from this flood frequency analysis was plotted as a function of the drainage area of the respective gage, as shown in Figure 2. From these points, least -squares best -fit lines were fit to the data and the equation of each line is shown in Figure 2. The drainage area of Newhall Creek at the proposed is 7.7 mi2, which would extrapolate all of the flows of the frequencies in Figure 2 well below 100 fees. Therefore, using these curves to establish historical flows by relating to other gage sites is not feasible. Alternatively, the records for all three gages were reviewed for flow magnitudes that are comparable to the peak flows estimated in Table 1. From these records, "wet' and "average" water years, corresponding to 2003 and 1962, respectively, were selected. There are several dry years but these do not yield significant aggradation and degradation. 4 Guidelines for Determining Flood Flow Frequency, Bulletin 17B, Interagency Advisory Committee on Water Data, USGS, March 1982. Hydraukc and Scour Study, Newhall Creek at Proposed Dockweiler Road Extension, Santa Clarita, California Figure 2. Flow -Drainage Area Relationship of Regional Gages Existing Topographic Conditions The digital terrain model of existing conditions was based on the 2 feet interval aerial topography provided from the City of Santa Clarita. Hydraulic Modeling Rivertech will develop an existing and post -project HEC-RASS hydraulic model of the Newhall Creek Channel at the proposed Dockweiler Road bridge crossing to determine the hydraulics parameters to be used in the scour analysis. The river tools of the Watershed Modeling System (WMS)6 software was used to develop a terrain model from the CAD drawings, from which a flow line was delineated and cross sections were cut. This georeferenced data was exported to HEC—RAS, which served as the existing hydraulic model geometric base. Modifications were made to reflect the existing bridges, roughness and other input parameters. One bridge/culvert structure was included in HEC-RAS model. The Newhall Creek Channel Bridge consists of four box culverts with 24' span and 8' rise at the crossing with Lyons Avenue extension. Using the HEC-RAS tool, the proposed Newhall Creek Channel floodplain limits ' HEC-RASRiver Analysis System, Version 4.1, US Army Corp of Engineers, Hydrologic Engineering Center, 2010. 6 Watershed Modeling System (WMS), Version 9.1. Aquaveo, www.aquaveo.com, May 2014. Hydraukc and Scour Study, Newhall Creek at Proposed Dockweiler Road Extension, Santa Clarita, California were established. Water surface profiles and their associated hydraulic parameters were derived for Newhall Creek Channel Capital Flood scenario. Figure 3. Topography and River Stationing Study Boundary Conditions The Newhall Creek study reach boundaries are Placerita Creek and the survey limits (approximately 3,000 feet downstream of the SR14 crossing) at the downstream and upstream limits, respectively. Based on the available topographic survey, the average channel slope of 0.4% was applied to determine the downstream normal depth, which is added to the channel invert to arrive at the starting water -surface elevation. HYDRAULIC ANALYSIS AND RESULTS The proposed bridge, an extension of Dockweiler Road and Lyons Avenue over Newhall Creek Channel crossing was modeled using the culvert hydraulics computer program HY-8.' The proposed four 24-feet wide and 8-feet deep opening reinforced concrete bridge will accommodate the Capital Flood. 7 Culvert Hydraulics, HY8, Version 7.3, Federal Highway Administration developed in cooperation with Aquaveo LLC and Environmental Modeling Research Laboratory.

Hydraulic Sections, Plan View Based on the LACFCD Sedimentation Manual recommendation for the Santa Clara River watershed, it is proscribed that the Newhall Creek be improved as a soft bottom channel with protected levees. To convey the Capital Flood, a discharge of 9,200 fel, the proposed channel section will require a trapezoidal section with an 80-foot wide base and 2:1 lined side slopes. This section is similar to the existing upstream improvements at Del Oro Street crossing with Newhall Creek. HEC-RAS model input and output data, including cross sections and detailed tables are provided in the Appendix for reference. The floodplain map for Capital peak flow is provided in the Appendix. Existing Condition The cut sections using the WMS river tools were imported into HECRAS as georeferenced geometry. This geometric data was then modified and amended to accurately reflect the hydraulic characteristics, e.g., bridges, channel banks, roughness, etc. The model includes the Railroad Avenue and Southern Pacific Railway bridges. Boundary conditions, i.e., flows and starting water -surface elevations, were added to complete the model. Figure 5 illustrates the resulting water -surface profiles for the existing condition. The detailed input and output of the existing condition hydraulic model is exhibited in the appendix.

Water -Surface Profile, Existing Condition Post -Project Condition The implementation of the proposed bridge and channel widening are two significant components of the post -project hydraulic model. The bridge has four 25-foot wide and 8-foot deep openings. The approach to the bridge is an improved channel that is trapezoidal in shape with na 80-foot bottom width and 2:1 aide slopes. The hydraulic sections and input from the existing condition model was the basis for the post - project with the implementation of the proposed bridge and channel widening. The results of the HEC-RAS hydraulic model output indicate that the proposed bridge and channel improvement will accommodate the Capital Flood, i.e., no overtopping of the road, and will not create any flood hazard for the adjacent railroad and proposed street improvements. The bridge conveys both the 50-year bum/bulk and FIS 100-year flood flows with more than 2 feet of freeboard. Figure 6 illustrates the resulting water -surface profiles for the post -project scenario. The detailed input and output of the post -project scenario hydraulic model is exhibited in the appendix.

Water -Surface Profile, Post -Project Scenario SCOUR ANALYSIS The results of the post -project hydraulic model were used to determine the long-term aggradation/degradation process. We will determine total maximum scour, which would include bank and bed erosion, bend (if measurable) and contraction/expansion influences. Scour Analysis The first part of the study is to determine the potential scour due to the implementation of the project. The three scour processes that occur are long-term, contraction and bend scour — the latter due to the natural bend in the exit segment of the study reach. The results of the HEC-RAS model were used to define the hydraulic characteristics required as input for the scour and shear stress analyses. Long -Term Scour, Sediment Transport The bed -material load models available in the HEC-RAS program are, as follows: Yang (1973), Laursen (1958), Ackers and White (1973), Engelund and Hansen (1967), Meyer -Peter and Hydraukc and Scour Study, Newhall Creek at Proposed Dockweiler Road Extension, Santa Clarita, California Muller (1948) and Einstein (1950).8 The Meyer -Peter and Muller equation is recommended for bed material coarser than 5 mm, which does not apply for this stream system in this model, so it was not used. Ackers and White or Engelund and Hansen's equation is recommended for subcritical flow in the lower flow regime. However, there is a mixed flow where some reaches are subcritical and supercritical flow, so this system may not be the most appropriate application of these methods. The Laursen equation is best suited for laboratory flumes and shallow rivers with fine sand or coarse silt. The Yang equation is recommended for sand transport in laboratory flumes and natural rivers, which is an appropriate application for this stream system. Fall velocity is computed using the Toffaletti equation, the recommended method for sand -bed rivers, which is the case for this application. The default extent of erodible lining is set to the cross section bank limits. The maximum depth of erodibility is a user -defined input and limits the lower limit to which degradation is set. Boundary Conditions: Sediment Load The input options in the HEC-RAS sediment transport module for sediment load are equilibrium load, rating table and user -defined sediment load series. Lacking any historical sediment load data, the equilibrium load was applied. Sensitivity analysis, Sediment Transport The various applicable transport functions, including Yang, Ackers and White, Engelund and Hansen, Copeland and Laursen were considered and evaluated for this model. The results of these bed -material load models yielded similar results but the Yang method was most consistent and stable, so it is the recommended method. The modeling results in this study reflect the Yang method. Using the nationwide guidelines for long-term aggradation/degradation, and the HEC-RAS hydraulic model implementation of HEC-6, we developed a sediment transport model, using the Yang (sand) methodology. This type of scour is not a result of a specific single event but rather a series of events over time. Observed (gage) data is not available in Newhall Creek or the South Fork of the Santa Clara River so an approximation of the flood flow is made to estimate the potential long-term scour. The sediment transport model simulated a series of time -varied flows with varying durations for a poorly graded sandy channel to determine the maximum scour depth for peak flows of 4,620 and 7,290 fees, corresponding to water years 1962 and 2003. Soil samples were taken along the bed and bank and used in the laboratory sieve analyses, which yielded particle size distribution curves, shown in Figure 7, that were input in the sediment transport models. As can be seen in Figure 7, the median grain size for the two samples are 1.0 and 2.0 mm, respectively. a Sedimentation Engineering, Processes, Measurements, Modeling and Practice, ASCE Manual No. 110, American Society of Civil Engineers, Reston, VA, 2007.

Particle Size Distribution Curves Figure 8 illustrates the maximum aggradation and degradation event, which corresponds to water year 1962. The system is in balance with the upper reaches deposit zones and the lower reaches erosion zones. As can be seen, the proposed bridge causes aggradation in the approach sections and a minor scour depth in the exit sections adjacent to the bridge. Hence, the computed maximum scour depth, set to 0.3 feet, corresponds to a simulation time of one year. The results of this analysis are presented in the appendix.

Particle Size Distribution Curves Contraction Scour Using the nationwide guidelines for contraction scour9 and the HEGRAS hydraulic model developed for the site, we estimated the potential scour due to contraction caused by the transition in the exit section back to the existing channel.

Hydraukc and Scour Study, Newhall Creek at Proposed Dockweiler Road Extension, Santa Clarita, California Where: ys is the average contraction scour depth; yl and y2 are average depth in upstream main channel and contracted section, respectively; yo is existing depth in contracted section before scour; QI and Q2 are flows in upstream and contracted sections, respectively; and WI and Wz are bottom widths in upstream main channel and contracted section, respectively. For this analysis, the relevant grain sizes were obtained from a sieve analysis of a soil sample in the scour zone.10 The input and output for this analysis are exhibited in the appendix. The HEC- RAS results yield a contraction scour depth of 0.0 feet for the proposed bridge. The pier scour, using the CSU equation, is negligible but the abutment scour is estimated to be 22.2 feet and 27.3 feet, for the Capital Flood and FIS 100-year, respectively. The total maximum potential scour is the sum of the long-term, contraction, pier and abutment scour which is conservative estimate of 27.6 feet. Bend Scour We estimated the potential scour at the bend using Maynord's equation, as documented in HEG 23:" D.b =1.8 — 0.051 R` + 0.0084 W Dmn� W Dmnc Where: Dmxb is the maximum water depth in the bend; Dm„, is the average water depth in the crossing upstream of the bend; W is the width of the bend; and R, is the centerline radius of the bend. For this stream bend, we determined that R,, Wand length of curvature, L, are 265, 137 and 500 feet, respectively. The computations for this analysis are exhibited in the appendix. The results for the Capital Flood and FIS 100-year yield bend scour depths of 2.4 and 2.3 feet, respectively. Streambank Mechanics There is a bend that is located approximately 500 downstream of the proposed bridge and is therefore within the hydraulic zone of influence. Associated with this bend is a concentration of shear stress directed to the right (east) bank of the Newhall Creek channel. Erodibility Index Method Erosion potential within the channel can be assessed using the Erodibility Index Method (EIM)12 and Shields Parameter. These approaches have been used in this study to assess the stability of the study reach. EIM determines that power of the stream flow and compares it to the power to resist by the channel lining, which in this case is sand. 10 Laboratory Soil Test Results, performed by Kling Consulting Group, Inc., February 2014 11 Bridge Scour and Stream Instability Countermeasures, Experience, Selection and Design Guidance, Third Edition, Hydraulic Engineering Circular No. 23, Publication No. FHWA NHI-09-111, p. 4.10, Federal Highway Administration, September 2009. 12 Scour Technology, Annandale, G.W.

Stream Power Radial Stress We estimated the shear stress at the bend using Begin's approach, as documented in HEC-23: 13The radial stress, i.e., the shear stress on the outer bank in a bend is defined as: F pQV �Y=A = W b YR, + � Where: Ab is area of the outer bend; tp, is radial stress; F is centripetal force; pis fluid density; Q is discharge; V is velocity; and Y is mean flow depth. The computations for this analysis are exhibited in the appendix. The results of the Capital Flood and FIS 100-year yield bend shear stresses of 60.4 and 47.2 lb/fe, respectively. From the HEC- 13 Bridge Scour and Stream Instability Countermeasures, Experience, Selection and Design Guidance, Third Edition, Hydraulic Engineering Circular No. 23, Publication No. FHWA NHI-09-111, p. 4.11, Federal Highway Administration, September 2009. Hydraukc and Scour Study, Newhall Creek at Proposed Dockweiler Road Extension, Santa Clarita, California RAS hydraulic model, the average shear stresses on the bed in the bend reach are 1.3 and 0.9 lb/ft2. Therefore, the total shear stress is the sum of the average shear stress on the bed and radial shear stress which is 61.7 and 48.1 lb/ft2, respectively. These estimates are extremely conservative, so verification with another methodology would be advisable. Chang's Stream Power As an alternative approach, we applied the more robust Chang Transverse Stream Power methodology with the aid of the Mathcad14Computer program. This application is too complex to summarize in the body of this letter so the input and output for this analysis are exhibited in the appendix. The results yield a total calculated shear stress, -cc, on the outer streambank of 7.7 lb/fe, which is the design shear stress that is recommended. So any lining of the channel along the bend would have to greater than or equal to 7.7 lb/ft2 to be stable. SCOUR COUNTERMEASURES In addition to the vegetative treatment proscribed in the prior section, there are high shear zones in the exit section of the proposed bridge where more robust countermeasures may be required. Based on the results of the hydraulic and scour analyses, we are prescribing lining and energy dissipators to resist the computed erosive forces and recommend mitigation measures. With the aid of HY8 and the methodology of HEC-1415, countermeasures to mitigate the highly -erosive exit velocities of the proposed bridge were evaluated. The feasible alternatives, whose criteria were met by the proposed bridge and hydraulic characteristics, are limited to the following streambed level structures: riprap basin, CSU Basin and Contra Cost Basin, the latter two being rigid structures. The riprap basin, illustrated in typical plan and sections in Figure 10, is recommended but comes with a relatively large footprint, with a total length of 400 feet and width of 366 feet, both of which will need to be reduced to fit the channel physical constraints.

Riprap Basin, Profile View I,'IDIM 0101AL1I17.IV0[1 L1MA1►11ZKIIL1IMP11MML1I In summary, the existing Newhall Creek Channel does not have the capacity to convey the FIS 100-year and the Capital Flood flow rates. As a result, the 100-year model results show that a significant percentage of the flow spill out the main channel and flood the railroad, entering the Railroad Avenue. As part of the proposed Dockweiler Road / Lyons Avenue extension, there are four 25-foot wide and 8-foot deep openings in a concrete box bridge at the crossing of the Newhall Creek channel and the channel improvement to trapezoidal sections with 80-foot wide soft base and 2:1 protected side slopes. The proposed improvements accommodate Capital Flood, with no overtopping, and will not create any flood hazard for the adjacent railroad and proposed street improvements. The results of this study provide the calculated shear stress on the streambank. In order to protect the streambank from erosion, a lining with a permissible shear stress, zp, greater than z, must be installed. Riprap and vegetation linings are recommended for the high and moderate shear zones, respectively. The two methodologies that we applied yield similar results, albeit, the HEC-23 radial stress approach is more conservative. In the respective documentations for the two approaches, it is stated that the HEC-23 has limited field verification, whereas, the Chang method has been more thoroughly verified with field data. Therefore, despite the conservatism of the HEC-23 approach, we recommend implementing a countermeasure that has a permissible shear stress, zp greater than the calculated shear stress, -cc as determined using the Chang Stream Power methodology. Sensitivity analysis, Sediment Transport The various applicable transport functions, including Yang, Ackers and White, Engelund and Hansen, Copeland and Laursen were considered and evaluated for this model. The results of these bed -material load models yielded similar results but the Yang method was most consistent and stable, so it is the recommended method. The modeling results in this study reflect the Yang method.

Conventional construction, but with closed windows and fresh air supply systems or air conditioning will normally suffice. NORMALY UNACCEPTABLE New construction or development should generally be discouraged. If new construction or development does proceed, a detailed analysis of the noise reduction requirements must be made and needed noise insullation features included in the design. Sound walls, window upgrades, and site design modifications may be needed in order to achieve City standards. CLEARLY UNACCEPTABLE New construction or development should generally not be undertaken. CONSIDERATIONS IN DETERMINATION OF NOISE -COMPATIBLE LAND USE A. NOISE EXPOSURE INFORMATION DESIRED Where sufficient data exists, evaluate land use suitability with respect to a worst -case value of CNEL. Usually, a future projection of noise levels represents the worst -case. Existing and future noise contours for freeways, roadway, airport and railroads are provided in the Noise Element. B. NOISE SOURCE CHARACTERISTICS The land use -noise compatibility recommendations should be viewed in relation to the specific source of the noise. For example, aircraft and railroad noise is normally made up of higher single noise events than auto traffic but occurs less frequently. Therefore, different sources yielding the same composite noise exposure do not necessarily create the same noise environment. The State Aeronautics Act uses 65 dB CNEL as the criterion which airports must eventually meet to protect existing residential communities from unacceptable exposure to aircraft noise. In order to facilitate the purposes of the Act, one of which is to encoumge land uses compatible with the 65 dB CNEL criterion wherever possible, and in order to facilitate the ability of airports to comply with the Act, residential uses located in areas with an aircraft noise level greater than 65 CNEL should be discouraged and considered located within normally unacceptable areas. Source: City of Santa Clarita Noise Element, 2011. C. SUITABLE INTERIOR ENVIRONMENTS One objective of locating residential units relative to a known noise source is to maintain a suitable interior noise environment at no greater than 45 dB CNEL. This requirement, coupled with the measured or calculated noise reduction performance of the type of structure under consideration, should govern the minimum acceptable distance to a noise source. D. ACCEPTABLE OUTDOOR ENVIRONMENTS Another consideration, which in some communities is an overriding factor, is the desire for an acceptable outdoor noise environment. The acceptable outdoor noise level is 65 CNEL for rear yard areas, neighborhood parks, and pool recreation a reas at multi -family developments. PARKER Figure 4.8-1 ENVIRONMENTAL.

The City's General Plan includes several large developments in the area, and traffic volumes are expected to increase significantly. As such the City of Santa Clarita has identified a project to extend Dockweiler Drive to Lyons Avenue. The proposed Dockweiler Drive Alignment project is located in the City of Santa Clarita, approximately 35 miles northwest of the City of Los Angeles, in the Newhall area of the City. Sierra Highway and the SR-14 (Antelope Valley) Freeway provide a boundary for the study area along the eastern side. Through traffic access on Placerita Canyon Road is restricted with a gate entrance west of Sierra Highway. Placerita Canyon Road currently is the primary connection to The Master's College and residents to the north. Newhall Avenue on the southern boundary of the study area provides a direct connection for cross valley traffic and connects Sierra Highway and Railroad Avenue. The UP/Metrolink Railroad line restricts access to the west with three (3) existing at -grade railroad crossings located at 13t" Street, Market Street, and Newhall Avenue. Figure 1-1 illustrates the vicinity map and project location. The extension of Lyons Avenue to Dockweiler Drive across the existing Metrolink line has been identified by the City as one (1) of five (5) key transportation projects. The alignment is part of the City's General Plan and consistent with the goals of the Downtown Newhall Specific Plan, Santa Clarita Valley Consolidated Traffic Model (SCVCTM), and the Compass Blue Print Plan. The purpose of the Dockweiler Drive Alignment Project is to ascertain the feasibility of the General Plan alignment for Dockweiler Drive, which identifies the connection of Dockweiler Drive to Lyons Avenue at Railroad Avenue. The project would extend Lyons Avenue from its existing terminus at Railroad Avenue on the west to future Master College Master Plan Dockweiler extension at north of railroad crossing consistent with the Council -approved Compass Blueprint Concept Plan. This project would include the consideration of a new at -grade rail crossing at Lyons Avenue and Railroad Avenue, which is expected to result in the closure of the 13th Street rail crossing. This report examines the traffic impacts specifically for the No Build Condition, the Proposed Project, and two (2) Alternatives. The report also addresses the impacts of overall projected growth within the area to represent utilization of the proposed Dockweiler Drive Alignment alternative. Consideration will be provided to pedestrian, rail, and vehicular traffic within the study area. The study area is based on the North Newhall Specific Plan Stage II. 1.1 City Circulation Plan The Santa Clarita Valley's circulation system is a comprehensive transportation network of roadways, multi -use trails, bicycle paths, bus transit, and commuter rail. This network provides mobility options to Valley residents and businesses. Figure 1-2 illustrates a portion of the Santa Clarita Valley Circulation Plan bounded by the study area. A major component in the development of the Santa Clarita Valley is the inclusion of alternative travel modes and support facilities. These facilities increase efficiency and capacity of existing systems, by promoting mixed -use development near transit facilities. Bicycle lanes and accessibility to bike paths are a fundamental component to a comprehensive transportation network. Figure 1-3 illustrates a portion of the Santa Clarita Valley's Bicycle Master Plan bounded by the study area. OAKO Q RCyq RD DR, p ' MASTER' COLLEGES PLACERITA CANYON RD.

The Proposed Project and Alternatives consider combinations of constructing a new railroad crossing at Lyons Avenue and removing or improving the at -grade crossing at 131" Street. The alternatives are outlined as follows; Proposed Project The Proposed Project utilizes the City of Santa Clarita's General Plan proposed alignment for Dockweiler Drive, which identifies the connection of Dockweiler Drive to extend to Lyons Avenue. The Proposed Project would extend Lyons Avenue from its existing terminus at Railroad Avenue, eastward to Dockweiler Drive to provide a T-intersection. Included in the Proposed Project is reprofiling the intersection of Lyons Avenue and Railroad Avenue to allow the construction of a new SCRA/UP railroad grade crossing east of Railroad Avenue. The new Lyons Avenue railroad grade crossing will improve traffic movements and safety at the railroad crossing. The new crossing will allow the removal of the existing 13t" Street and Railroad grade crossing, which will avoid direct impact to the Placerita Canyon neighborhood. The Proposed Project is illustrated in Figure 1-4. Alternative 1 Alternative 1 utilizes the City of Santa Clarita's General Plan proposed alignment for Dockweiler Drive, which identifies the connection of Dockweiler Drive to extend to Arch Street. The project would extend Lyons Avenue from its existing terminus at Railroad Avenue, eastward to Dockweiler Drive to provide a T-intersection. Included in the Alternative 1 is reprofiling the intersection of Lyons Avenue and Railroad Avenue to allow the construction of a new SCRA/UP railroad grade crossing east of Railroad Avenue and construct improvements to the 13t" Street rail crossing. Alternative 1 is illustrated in Figure 1-5.

The Existing portion of Dockweiler Drive consists of one lane in each direction with a landscaped median and limited parking throughout the study area. Dockweiler Drive is used as the primary access to single- and multi -family residences. State Route 14 Freeway (SR 14) provides regional access within the study area. The freeway is a four -lane (two in each direction) facility with interchange access at Placerita Canyon Road and Newhall Avenue. Lyons Avenue is designated as an east -west major highway east of Railroad Avenue and Secondary Highway west of Railroad Avenue on the City of Santa Clarita Circulation Map Joint Highway Plan. Three lanes in each direction are provided with traffic signals and left turn channelization at major intersections. Newhall Avenue is designated as a north -south secondary highway from Lyons Avenue to Railroad Avenue with one lane in each direction. From Railroad Avenue to SR-14, Newhall Avenue is designated as a major highway with three northbound lanes and three southbound lanes south of Railroad Avenue. Newhall Avenue roadway designation is identified on the City of Santa Clarita Circulation Map Joint Highway Plan. Railroad Avenue (formerly San Fernando Road) is a north -south major highway from Magic Mountain Parkway to Lyons Avenue and a secondary highway from Lyons Avenue to Newhall Avenue. This roadway provides two lanes in each direction and limited parking throughout the study area. Railroad Avenue roadway designation is identified on the City of Santa Clarita Circulation Map Joint Highway Plan. Sierra Highway is an old alignment of SR-14 from Los Angeles to Mojave. It is designated as a north -south major highway on the City of Santa Clarita Map Joint Highway Plan. It is a four lane (two in each direction) with traffic signals and left turn channelization at major intersections. Placerita Canyon Road is an east -west local roadway. This roadway provides a gate at the western entrance. The gate provides restrictive access to residents of the Placenta Canyon neighborhood. 131" Street is an east -west unimproved local roadway. This roadway provides access to The Master's College and the Placenta Canyon neighborhood via its intersection with Railroad Avenue. One lane is provided in each direction. 9 As presented, in Figure 2-1, the project begins at the terminus of Dockweiler Drive 500 feet west of Valle Del Oro. Based on potential traffic impacts to the area roadways, seventeen (17) intersections have been identified for analysis; 1. Sierra Highway and SR-14 Freeway Southbound Ramps 2. Sierra Highway and Placerita Canyon Road 3. SR-14 Freeway Northbound Ramps and Placerita Canyon Road 4. Sierra Highway and Dockweiler Drive 5. SR-14 Freeway Southbound Ramps and Newhall Avenue 6.

Arch Street and 121" Street/Placerita Canyon Road 17. Lyons Avenue and Dockweiler Drive* The intersection denoted with an (*) is a future intersection Existing Traffic Volumes As referenced from the City of Santa Clarita Circulation Element, Average Daily Traffic (ADT) is a measurement of the average number of vehicles that travel a segment of roadway during a 24- hour period. The ADT is a useful benchmark for determining roadway capacities. Figure 2-1 illustrates the existing street system ADT and the study intersection locations. The existing 2013 ADT map for the Santa Clarita Valley is referenced from the city website. Figure 2-2 illustrates the existing peak hour traffic volumes in the study area. As referenced from the City of Santa Clarita Circulation Element, Peak hour information, which is the highest volume of traffic to pass over a road in a one -hour period, allows for a more detailed method of evaluating traffic conditions along roadways and intersections, and is used whenever operational analysis is required. The traffic volume data used in the intersection capacity analysis were based on traffic counts conducted by Newport Traffic Studies, an independent traffic data collection company. Turn movement counts were collected during the AM (7-9 AM) and PM (4-6 PM) peak periods at the above -mentioned existing intersections identified for detailed analysis. These counts were conducted in December 2012. The resulting turning movement volumes are presented in the Intersection Capacity Analysis Appendix of this report. 10 Q 0 j W OAK ORCHA RD DR.

Synchro is released by Trafficware Ltd, version 8. Synchro implements the methods of the 2010 Highway Capacity Manual, chapter 15, 16 and 17; Urban Streets and Signalized intersections. The analysis determines a level -of -service (LOS) which quantitatively describes the operating characteristics of signalized intersections and the maximum delay. The LOS ranges from "A" (the best) through "F" (system breakdown). The level - of -service is based on the average delay of vehicles at the intersections. Table 2-1 provides the LOS thresholds for signalized intersections per the HCM 2010 methodology. Table 2-1: HCM 2010 - LOS Criteria for Signalized Intersections LOS Control Delay per Vehicle (s/veh) A <10 B > 10 and <20 C > 20 and <35 D > 35 and <_ 55 E > 55 and <_ 80 F > 80 Source: HCM 2010 For un-signalized intersections the HCM measures the LOS based on the computed or measured control delay for Two Way Stop Controlled intersections (TWSC) and control delay for All Way Stop Controlled (AWSC) intersections. For a TWSC the LOS is computed for each movement and the most critical LOS is the one that describes the effectiveness of that intersection, which is typically the stop controlled left turn movement from the minor street. For an AWSC intersection the LOS defines the whole intersection. Table 2-2 provides the LOS thresholds for TWSC and AWSC intersections per the HCM 2010 methodology. Table 2-2: HCM 2010 - LOS Criteria for TWSC, AWSC, and Roundabout Intersections LOS Control Delay per Vehicle s/veh A <_ 10 B > 10 and <15 C > 15 and <25 D > 25 and <_ 35 E > 35 and <_ 50 F > 50 Source: HCM 2010 The intersection capacity analyses were conducted for the roundabout intersections using the Sidra Intersection Software. Sidra is released by Akcelik & Associated Pty Ltd, version 6.0. Sidra Intersection 6.0 implements the methods of the 2010 Highway Capacity Manual, Chapter 21. For the roundabout intersections the HCM measures the LOS based on the control delay and the LOS defines the whole intersection. The level -of -service is based on the average delay of vehicles at the intersections. Table 2-2 provides the LOS thresholds for roundabout intersections per the HCM 2010 methodology. The City of Santa Clarita preferred maximum acceptable level of service on arterial roads is LOS E. The City of Santa Clarita desired maximum acceptable level of service on residential neighborhood roads is LOS C or better. 13 Wo � 2.1 Existing Traffic Analysis To determine the impacts of the project to the study intersections, existing traffic intersection capacity analysis was conducted.

The proposed Dockweiler Drive Alignment project is enclosed by a residential community near The Master's College. Sierra Highway provides a boundary for the study area along the eastern side. Through traffic access on Placerita Canyon Road is restricted with a gate entrance west of Sierra Highway. Placerita Canyon Road currently is the primary connection to The Master's College and residents to the north. Newhall Avenue on the southern boundary of the study area provides a direct connection for cross valley traffic and connects Sierra Highway and Railroad Avenue. The UP/Metrolink Railroad line restricts access to the west with three (3) existing at -grade railroad crossings located at 13t" Street, Market Street, and Newhall Avenue. The study area is determined based on the North Newhall Specific Plan Stage II. The Dockweiler Drive Alignment project is intended to serve as a major east -west corridor link in the area to facilitate access to existing and planned development. The project is proposed to aid the future traffic consistent with the Santa Clarita Valley Consolidated Traffic Model (SCVCTM). Construction of this link is anticipated to reduce "cross valley" trip lengths and travel times, provide an alternate travel route, support a multi -modal transportation network by reducing bus travel times in the City and by providing the opportunity for increased bike and pedestrian traffic. Project Year 2019 Traffic Analysis A project year of 2019 has been identified as the opening year for the Dockweiler Drive Alignment project. As presented, a Proposed Project and two (2) alternatives have been identified and will provide varying distributions of traffic consistent with anticipated roadway utilization. A major factor in distribution of traffic is the anticipated growth within the study area due to development. The Year 2019 traffic volumes were provided by the City of Santa Clarita using the Santa Clarita Valley Consolidated Traffic Model (SCVCTM) for the Interim Year. Each alternative was modeled to account for the differing distribution of traffic dependent on the alternative. It is to be noted that Other Area Projects anticipated to be constructed by Year 2019, have been incorporated into the SCVCTM, and account for expected growth. The Year 2019 intersection turn movements were primarily taken directly from the Interim Year SCVCTM specific to each alternative. A few intersection turn movements were determined using existing counts and the link volumes from the Year SCVCTM specific to the alternative. These values were then used in a'Future Directional Link Volume (NCHRP 255)' calculator to determine Year 2019 Turn Movement Volumes. The intersections included were Valle Del Oro and Dockweiler Drive, Railroad Avenue and Market Street, Main Street and Lyons Avenue, Main Street and Newhall Avenue, Arch Street and 12t" Street/Placerita Canyon Road, Lyons Avenue and Dockweiler Drive, Aden Avenue and Dockweiler Drive, Aden Avenue and Placeritos Boulevard, Aden Avenue and Placerita Canyon Road. 3.1 No- Build Condition The Santa Clarita Valley Consolidated Traffic Model (SCVCTM) for Interim Year provided traffic volumes for the Project Year 2019 Condition. The model plots provided a No -Build Condition outlining the distribution of future traffic without the project.

This roadway is proposed to aid the future traffic growth consistent with the Santa Clarita Valley Consolidated Traffic Model (SCVCTM). Future Year 2035 Traffic Analysis Future Year 2035 traffic volumes were provided by the City of Santa Clarita using the Santa Clarita Valley Consolidated Traffic Model (SCVCTM) for the Buildout Year. Each alternative was modeled to account for the differing distribution of traffic dependent on the alternative. It is to be noted that Other Area Projects anticipated to be constructed by Year 2035, have been incorporated into the SCVCTM, and account for expected growth. The buildout includes construction of future roadways Golden Valley Road between Newhall Ranch Road to Valley Center Drive, Magic Mountain Parkway from Railroad Avenue to Via Princessa, and Via Princessa between Claibourne Lane and Sheldon Avenue. This also includes the proposed conceptual development of the North Newhall Specific Plan area an 809 dwelling unit plus an approximate 11 acre commercial land use. The Future Year 2035 intersection turn movements were primarily taken directly from the Buildout Year SCVCTM specific to the alternative. A few intersection turn movements were determined using existing counts and the link volumes from the Year SCVCTM specific to the alternative. These values were then used in a 'Future Directional Link Volume (NCHRP 255)' calculator to determine Future Year 2035 Turn Movement Volumes. The intersections included were Valle Del Oro and Dockweiler Drive, Railroad Avenue and Market Street, Main Street and Lyons Avenue, Main Street and Newhall Avenue, Arch Street and 12t" Street/ Placerita Canyon Road, Lyons Avenue and Dockweiler Drive, Aden Avenue and Dockweiler Drive, Aden Avenue and Placeritos Boulevard, Aden Avenue and Placerita Canyon Road. 4.1 No- Build Condition The Santa Clarita Valley Consolidated Traffic Model (SCVCTM) for Build -Out Year provided traffic volumes for the Future Year 2035 Condition. The model plots provided a No -Build Condition outlining the distribution of future traffic without the project. The analysis of No -Build Condition utilizes the traffic volume projections for the City of Santa Clarita's traffic model together with the existing traffic flow data. The traffic projections are based on the General Plan Buildout. The buildout includes construction of future roadways Dockweiler Drive between Railroad Avenue and Val Del Oro, Golden Valley Road between Newhall Ranch Road to Valley Center Drive, Magic Mountain Parkway from Railroad Avenue to Via Princessa, and Via Princessa between Claibourne Lane and Sheldon Avenue. This also includes the proposed conceptual development of the North Newhall Specific Plan area an 809 dwelling unit plus an approximate 11 acre commercial land use.

The nearest Metrolink train station to the proposed project is the Jan Heidt Newhall station located at Railroad Avenue and Market Street, approximately 0.25 mile south of Lyons Avenue. Currently the rail line serves approximately eight (8) freight trains per day with thirty (30) Metrolink commuter trains per weekday; twelve (12) on Saturday and six (6) trains Sunday. Passenger service from the Newhall station southbound to Los Angeles is provided by fourteen (14) trains per weekday starting at approximately 5:00 AM and ending at 7:30 PM. Passenger service northbound to Lancaster from the Newhall station is also provided by nine (9) trains starting at 7:00 AM until approximately 10:00 PM. Traffic Counts were compiled for the existing railroad crossings at 131" Street, Market Street, and Newhall Avenue. AM and PM peak hour traffic counts included the existing vehicles, pedestrians, and bicycle volumes. Table 5-1 presents the existing traffic counts. For a comparison of the three Dockweiler Drive extension alternatives, Daily and AM and PM Peak hour traffic volumes were compiled for the Year 2019 and 2035 conditions as presented in Table 5-2 and Table 5-3 respectively.

Furthermore the City and County must coordinate with regional transportation plan. Consideration to said code the City of Santa Clarita utilized regional plans affecting the Santa Clarita Valley. Those regional plans included California Department of Transportation (Caltrans); the Regional Mobility Plan prepared by the Southern California Association of Governments (SCAG); the Los Angeles Metropolitan Transportation Authority's (MTA or Metro) Congestion Management Program and bicycle way strategic plan; Santa Clarita Transit's Transportation Development Plan (TDP); and Los Angeles County's Airport Land Use Plan. The Santa Clarita Valley's circulation system provides vital connections linking neighborhoods, services, and employment centers throughout the community and the region. A comprehensive transportation network of roadways, multi -use trails and bicycle paths, bus transit, and commuter rail provides mobility options to Valley residents and businesses. Planning for the ultimate location and capacity of circulation improvements will also enhance economic strength and quality of life in the Valley. Consideration to the Santa Clarita Valley's continued development of efficient, cost-effective and comprehensive transportation systems that are consistent with regional plans, and local needs. The Circulation Plan identifies and promotes a variety of techniques for improving mobility that go beyond planning for construction of new streets and highways. A major component in the development of the Santa Clarita Valley is the inclusion of alternative travel modes and support facilities. These facilities increase efficiency and capacity of existing systems, by promoting mixed -use development near transit facilities. Bicycle lanes and accessibility to bicycle paths are fundamental to a comprehensive transportation network. The Santa Clarita Valley's Bicycle and Pedestrian Facilities is provided in Figure 6-1. As illustrated in Figure 6-1, Potential Bike Lane connectors are proposed from Dockweiler Drive to connect to the Proposed Class I Bike Path along Railroad Avenue and the Proposed Class I Bike Path along Railroad Avenue. 58 PROPOSED CLASS 1 BIKEPATH w J a U cn 0 0 z PLA CFRITA =N�,oNR D PROPOSED CLASS 2 BIKELANE POTENTIAL \ 9\ BIKE LANE CONNECTORS PROPOSED CLASS 1 BIKEPATH 3 `s FIGURE 6-1: SANTA CLARITA VALLEY'S EXISTING wE BICYCLE & PEDESTRIAN FACILITIES mE PROPOSED EXPANSION OF O DAVID EVANS DOCKWEILER DRIVE z$ aN°A880CIATE8 1NC• SANTA CLARITA, CALIFORNIA o 7 PROJECT IMPACT, MITIGATION, AND SUMMARY The following is an outline of the recommended traffic mitigation measures for the Proposed Project and each of the alternatives. 7.1 Proposed Project Year 2019 Project Mitigations 1.

approved Dockweiler Drive Extension Project. Modifications to the Lyons Avenue/Dockweiler Drive Extension Project will require approval of certain discretionary actions by the City of Santa Clarita, and therefore, is subject to environmental review requirements under the California Environmental Quality Act (CEQA). For purposes of complying with CEQA, the City of Santa Clarita, located at 23920 Valencia Boulevard, CA 91355, is identified as the Lead Agency for the Project. The analysis presented below conservatively evaluates the comparison of environmental impacts associated with the Lyons Avenue/Dockweiler Drive Extension Project (herein referred to as "Original Project"), the approved Alternative 2 Project (herein referred to as "Approved Project") and the Modified Project, and provides substantial evidence to demonstrate that any potential environmental impacts associated with the Modified Project would not result in new significant environmental effects or a substantial increase in the severity of previously identified significant effects. This section contains an assessment and discussion of impacts associated with the environmental issues and subject areas identified in the Initial Study Checklist (Appendix G to the State CEQA Guidelines, (C.C.R. Title 14, Chapter 3, 15000-15387), as amended on January 1, 2019. 1.2 ADDENDUM TO AN EIR Pursuant to Section 15164 of the State CEQA Guidelines (a) and (d), the lead agency shall prepare an addendum to a previously certified EIR if some changes or additions are necessary but none of the conditions described in Section 15162 calling for preparation of a subsequent EIR have occurred. The decision -making body shall consider the addendum with the final EIR prior to making a decision on the project. Pursuant to Section 15162 of the State CEQA Guidelines, the requirement to prepare a Supplemental or Subsequent EIR is only triggered when an EIR has been certified for a project, and one or more of the following occur: a) Substantial changes are proposed in the project which will require major revisions of the previous EIR due to the involvement of new significant environmental effects or a substantial increase in the severity of previously identified significant effects; Lyons Avenue/Dockweiler Drive Extension Project Addendum 1. Introduction SCH No. 2013082016 Page 1-1 City of Santa Clarita May 2021 b) Substantial changes occur with respect to the circumstances under which the project is undertaken which will require major revisions of the previous EIR due to the involvement of new significant environmental effects or a substantial increase in the severity of previously identified significant effects; or c) New information of substantial importance, which was not known and could not have been known with the exercise of reasonable diligence at the time the previous EIR was certified as complete, shows any of the following: i. The project will have one or more significant effects not discussed in the previous EIR or negative declaration; ii. Significant effects previously examined will be substantially more severe than shown in the previous EIR; iii. Mitigation measures or alternatives previously found not to be feasible would in fact be feasible, and would substantially reduce one or more significant effects of the project, but the project proponents decline to adopt the mitigation measure or alternative; or iv. Mitigation measures or alternatives which are considerably different from those analyzed in the previous EIR would substantially reduce one or more significant effects on the environment, but the project proponents decline to adopt the mitigation measure or alternative. The following information provides substantial evidence to support the conclusion that none of the conditions described in Section 15162 calling for preparation of a Supplemental or Subsequent EIR have occurred. Provided below is a discussion of each environmental category and CEQA checklist questions with respect to the changes between the Approved Project and the Modified Project, and where applicable, the Original Project and the Modified Project. The analysis presented below provides substantial evidence to demonstrate that any potential environmental impacts associated with the Modified Project would not be substantially greater than the impacts that were previously identified in the adopted Final EIR, and that no new significant impacts would result. Based on the findings presented below, the proposed modifications would not rise to the level warranting re -circulation of the Final EIR. A summary of the Original Project, and Approved Project, and details of the Modified Project, are provided below in Section 2, Project Description, of this Addendum. 1.3 OVERVIEW OF THE LYONS AVENUE/DOCKWEILER DRIVE EXTENSION PROJECT The Original Project was analyzed in the Final EIR as a multi -phased capital improvement project being coordinated by the City of Santa Clarita and The Master's University to improve circulation and access to the Placerita Canyon and Newhall Communities. The proposed connection and extension of Lyons Avenue to Dockweiler Drive is identified in the Circulation Element of the City's General Plan as one of the primary Lyons Avenue/Dockweiler Drive Extension Project Addendum 1. Introduction SCH No. 2013082016 Page 1-2 City of Santa Clarita May 2021 east -west arterials through the City of Santa Clarita that would provide a through connection from Sierra Highway to Railroad Avenue. CEQA Findings Based on the analysis of the Final EIR (see Section 4.0 Environmental Analysis of the EIR), implementation of the Original Project would result in significant and unavoidable environmental impacts associated with the following environmental issues: • Construction air quality (localized PM,o and PM2.5 emissions) • Construction related noise impacts As discussed in Section 4.2 Air Quality, of the EIR, the Original Project would result in significant localized air emissions in close proximity to residential land uses within 100 meters of the Project Site on a temporary and intermittent basis during construction. Localized NO,, and CO emissions would be below the significance thresholds at all sensitive receptor locations. However, localized thresholds would be exceeded for PM,o and PM2.5 emissions at two locations: (1) the single-family residential land uses located immediately north of the Project Site (within a proximity of 100 meters) and (2) the residential land uses within 100 meters south of the Project Site in the vicinity of Market Street and Race Street. Localized emissions would be below the stated thresholds for any land use located further than 100 meters from the Project Site. Therefore, localized air quality impacts resulting from construction activities would be considered significant and unavoidable. As discussed in Section 4.8 Noise, of the EIR, the Original Project's construction noise impacts would exceed the maximum allowable exterior noise levels. Thus, the Original Project's construction noise impacts would be considered a significant impact on a short term and intermittent basis during the construction period. As summarized in Section 1.0 Executive Summary, Table 1-1 Summary of Environmental Impacts and Mitigation Measures, of the EIR, all other environmental impacts were mitigated to less than significant levels with mitigation. Project Alternatives The Final EIR analyzed four alternatives to the Original Project: No Project, Alternative 1 Project (Proposed Alignment with the 13th Street Rail Crossing), Alternative 2 Project (Proposed Alignment to Arch Street without Lyons at Grade Crossing) and the Market Street Alignment. Based on a review of the alternatives identified in the EIR, none of the Alternatives would be effective in eliminating the Original Project's significant and unavoidable impacts. A summary of the impact conclusions for each alternative relative to the impact statements for each impact areas evaluated in the EIR Lyons Avenue/Dockweiler Drive Extension Project Addendum 1. Introduction SCH No. 2013082016 Page 1-3 City of Santa Clarita May 2021 for the Original Project is presented in Section 6.5 Environmentally Superior Alternative, Table 6.5-1, Environmentally Superior Alternative Matrix. Of the alternatives evaluated, the Alternative 2 Project (Approved Project) would reduce the footprint of the Project Site, as it excludes the Lyons Avenue Extension to Dockweiler Drive and maintains the at -grade crossing at 13th Street. The Approved Project would involve the development of the proposed roadway alignment and associated infrastructure for Dockweiler Drive, which would extend Dockweiler Drive to Arch Street. The route would continue along Arch Street to 13th Street to link to Railroad Avenue. Unlike the Original Project, the Approved Project does not include the roadway segment between the Dockweiler extension and Lyons Avenue, which spans a portion of the Newhall Creek. Additionally, the Approved Project proposes to maintain and improve the 13th Street rail crossing. As evaluated in Section 6.5 Environmentally Superior Alternative, of the EIR, the Approved Project was identified as the environmentally superior alternative as it would feasibly attain most of the basic objectives of the Original Project to provide an additional connection from the Old Town Newhall community to Dockweiler Drive as contemplated under the Circulation Element of the General Plan, and although it would not reduce or eliminate the Original Project's significant and unavoidable short-term localized construction air quality and construction noise impacts, it would reduce impacts associated with air quality, biological resources, cultural resources, geology/soils, hydrology, construction noise, aesthetics and traffic. Specifically, the Approved Project would retain the existing aesthetic conditions and views at the Lyons Avenue and Railroad Avenue intersection, would avoid ground disturbance within Newhall Creek, and would reduce the total combined number of railroad crossing events at 13th Street, Market Street, Newhall Avenue and Lyons Avenue. Adoption of the Final EIR The City Council considered the environmental information contained in the Final EIR, Statement of Facts and Findings and Statement of Overriding Considerations Regarding Environmental Effects for the Original Project and determined that it is adequate pursuant to CEQA. The City Council found there is substantial evidence that supports the conclusion that the environmentally superior alternative (Alternative 2/Approved Project) would result in community benefits, including specific ecological, economic, legal, social, technical, and other benefits, that outweigh the significant effects of the project on the environment that cannot be mitigated to a level less than significant. The City Council certified the Final EIR and associated documents and adopted the MMRP and Statement of Overriding Considerations'. ' City of Santa Clarita, Resolution No. 18-11.

Introduction SCH No. 2013082016 Page 1-4 City of Santa Clarita May 2021 1.4 OVERVIEW OF THE ENVIRONMENTAL REVIEW PROCESS The Notice of Preparation (NOP) and Notice of a Public Scoping Meeting was circulated for public review and comments for a 30-day period beginning on August 5, 2013 and ending on September 3, 2013. The public scoping meeting was held on August 21, 2013, to obtain the public's initial views about environmental issues that should be evaluated in the EIR. The EIR was published on August 16, 2017 and circulated for review and comment for a period of 60 days. The public review period ended on October 16, 2017. The Notice of Completion/Notice of Availability (NOC/NOA) was published in The Signal and was posted with the Los Angeles County Clerk's office on August 16, 2017. Additionally, two public outreach meeting were held on September 14, 2017 and September 28, 2017 at The Master's University. City staff and representative technical consultants involved in the preparation of the EIR attended the outreach meetings to provide the public with a summary of the EIR and obtain questions and comments on the EIR from the public. On February 27, 2018 the City conducted a Public Hearing and received the staff report, presentation and public comments for the Dockweiler Drive Extension Project. On April 10, 2018 the City Council continued the Public Hearing, certified the Final EIR and adopted a resolution approving the alignment of the Dockweiler Drive Extension as described in the Final EIR as the Alternative 2 Project. Lyons Avenue/Dockweiler Drive Extension Project Addendum 1. Introduction SCH No. 2013082016 Page 1-5 [Page left intentionally blank.] 2.0 PROJECT DESCRIPTION 2.1 PROJECT LOCATION The Project Site is located in the City of Santa Clarita, California, about 35 miles north of Downtown Los Angeles. The Project Site is located in the Newhall community of the City of Santa Clarita at the intersection of 13th Street and Railroad Avenue and extends eastward towards the General Plan alignment for Dockweiler Drive towards The Master's University and northwest towards the intersection of 12th Street and Arch Street. The limits for the Dockweiler Drive extension ("Project Site") are generally from Railroad Avenue and 13th Street on the west to the future The Master's University Master Plan Dockweiler extension to the east (see Figure 2-1). 2.2 PROJECT SETTING The Project Site consists of segments of Railroad Avenue, 13th Street, Arch Street, 12th Street, and Placenta Canyon Road roadways, the UP/Metrolink Railroad line, which runs parallel to Railroad Avenue between 13th Street and 15th Street, and undeveloped land to the east extending towards Arch Street and The Master's University. The west end of the Project Site traverses a storage yard, utilized by Los Angeles County Department of Public Works, and private properties. The portion of the Project Site that includes the intersection of Railroad Avenue and 131h Street is developed with existing road surface and an at -grade crossing. The UP/Metrolink railroad line crosses the Project Site at the intersection of Railroad Avenue and 13th Street and extends north along Railroad Avenue to approximately 15th Street. The conditions of the Project Site are depicted in Figure 2-2. 2.3 SURROUNDING LAND USES The Project Site is located immediately southwest of the Placenta Canyon community and east of the Old Town Newhall community. The portion of the Project Site to the east of the intersection of Railroad Avenue and Lyons Avenue is bounded by commercial and industrial uses to the north, a landscape nursery to the southeast, the Newhall Metrolink Station to the south and the Old Town Newhall Library and commercial uses to the west, across Railroad Avenue. A portion of the Project Site to the east of the intersection of Railroad Avenue is bounded by undeveloped land to the north, commercial and industrial uses to the east, Newhall Creek to the south and commercial buildings to the west, across Railroad Avenue. Subsequent to the adoption of the EIR, a five -story parking garage and five -story mixed -use apartment complex (Newhall Crossings) were constructed at the southwest corner of Railroad Avenue and Lyons Avenue.

The Modified Project would include roadway and grading improvements along Placenta Canyon Road to connect to the proposed Arch Street, Dockweiler Drive and 12th Street roundabout. The Modified Project would also include the reprofiling of the UP/Metrolink railroad line between approximately 13th Street to approximately 15th Street to meet grade and the improved 13th Street and Railroad Avenue intersection. As such, land uses within the Project Site vicinity would include additional single-family residential uses located near the intersection of Placerita Canyon Road and Aden Avenue, and additional single- and multi -family residential uses located between Railroad Avenue and Walnut Street between 13th Street to 15th Street. Surrounding land uses are depicted in Figure 2-3. 2.4 ZONING AND GENERAL PLAN LAND USE DESIGNATIONS The Project Site is currently zoned for MXN (Mixed Use Neighborhood). The portion of the Project Site that crosses the UP/Metrolink Railroad line is zoned for PI (Public Institutional). The General Plan land use designation of the Project Site is Mixed Use Neighborhood (MXN). The Project Site is also located in the Placerita Canyon Special Standards District (PCSSD) and is part of the North Newhall Area (NNA), which includes a Planned Development Overlay Zone. Properties to the north of the Project Site are zoned MXN. Properties to the south of the Project Site are zoned Specific Plan (SP). Properties to the east of the Project Site are zoned Urban Residential 1 (URI), Urban Residential 3 (UR3) and Public Institutional (PI). Properties to the west, across Railroad Avenue are zoned SP (see Section 2.0 Project Description, Figure 2-5, Zoning and Land Use Map of Project Site and Surrounding Area, of the EIR). 2.5 APPROVED PROJECT Lyons Avenue/Dockweiler Drive Extension Project (Original Project) The Original Project included the extension of Lyons Avenue from Railroad Avenue southeast to the proposed connection with Dockweiler Drive, the addition of a new at -grade railroad crossing east of the Railroad Avenue and Lyons Avenue intersection, a roadway bridge overcrossing above Newhall Creek, and the extension of Dockweiler Drive from the approved alignment of Dockweiler Drive at The Master's University site, and northwest to connect with the intersection of Arch Street and 12th Street. The Original Project would have extended Lyons Avenue from its existing terminus at Railroad Avenue, eastward to Dockweiler Drive to provide a T-intersection at Dockweiler Drive (see Figure 2-3 Photographs of Surrounding Land Uses and Figure 2-4 Lyons Avenue/Dockweiler Drive Extension Project Site Plan). In coordination with the proposed Railroad Bike Path project, the extension of Dockweiler Drive would result in creating a vital Complete Street link between the communities to the east of the railroad/ Newhall Creek (including The Master's University) and Old Town Newhall and Metrolink station. The Original Project also included the closure of an at -grade railroad crossing at the intersection of 13th Street and Railroad Avenue. The intersection at 13th Street would be modified by removing the northbound right turn lane and southbound left turn lane and restricting the eastbound through movement. Lyons Avenue/Dockweiler Drive Extension Project Addendum 2. Project Description SCH No. 2013082016 Page 2-4 City of Santa Clarita May 2021 Alternative 2 Project (Approved Project) Similar to the Original Project, the Approved Project would involve the development of the proposed roadway alignment and associated infrastructure for Dockweiler Drive, which would extend Dockweiler Drive to Arch Street. The route would continue along Arch Street to 13th Street to link to Railroad Avenue. Unlike the Original Project, the Approved Project does not include the roadway segment between the extension of Dockweiler Drive and Lyons Avenue, which spans a portion of the Newhall Creek. Additionally, the Approved Project avoids the addition of a new at -grade railroad crossing and instead proposes to maintain and improve the 13th Street rail crossing (see Figure 2-5 Alternative 2 Project Site Plan). Under the Approved Project, the existing westbound travel lanes on 13th Street approaching Railroad Avenue would be improved by adding two westbound lanes and a median, with one dedicated left turn lane, one shared through lane and left turn lane, and one dedicated right turn lane. The eastbound traffic lanes on 13th Street would be improved to provide two through travel lanes. The existing median nose on Railroad Avenue would be removed to reconfigure the four southbound lanes to provide two protected left turn lanes, one dedicated through lane and one shared right turn lane and through lane. The northbound lanes on Railroad Avenue would provide two through lanes, one protected left turn lane and one protected right turn lane. Similar to the Original Project, the intersection of Arch Street, 12th Street, Placenta Canyon and Dockweiler Drive would be improved with one of three intersection design configurations. The Approved Project would require improvements to Arch Street and 13th Street to accommodate traffic from the extension of Dockweiler Drive to Arch Street. Roadway improvements would require increasing the width of Arch Street and 13th Street, which would affect several surrounding properties. As discussed above in Section 1.3, and evaluated in Section 6.5 Environmentally Superior Alternative, of the EIR, the Approved Project was identified as the environmentally superior alternative as it would feasibly attain most of the basic objectives of the Original Project. Although it would not reduce or eliminate the Original Project's significant and unavoidable short-term localized construction air quality and construction noise impacts, it would reduce impacts associated with air quality, biological resources, cultural resources, geology/soils, hydrology, construction noise, aesthetics and traffic.

PARKER Figure 2-5 erwi--N-1..1 11 Alternative 2 Project Site Plan City of Santa Clarita May 2021 2.6 MODIFIED PROJECT Similar to the Approved Project, the Modified Project would extend Dockweiler Drive from its existing terminus, westward to intersect with Arch Street and 13th Street, providing a 4-legged roundabout with a signalized offset T-intersection with Placerita Canyon Road, as depicted in Figure 2-6 Modified Project Site Plan. A proposed pedestrian and bicycle bridge would cross over Newhall Creek to connect with the northwest end of the Newhall Metrolink Station parking lot, located to the south of the proposed Dockweiler Drive roadway extension. Railroad Avenue and 13`h Street Improvements Like the Approved Project, the existing westbound travel lanes on 13th Street approaching Railroad Avenue would be improved by adding two westbound lanes and a median, with one dedicated left turn lane, one shared through lane and left turn lane, and one dedicated right turn lane. The eastbound traffic lanes on 13th Street would be improved to provide two through travel lanes. The existing median nose on Railroad Avenue would be removed to reconfigure the four southbound lanes to provide two protected left turn lanes, one dedicated through lane and one shared right turn lane and through lane. The northbound lanes on Railroad Avenue would provide two through lanes, one protected left turn lane and one protected right turn lane (see Figure 2-7). Arch Street, Dockweiler Drive and 12`h Street Roundabout As depicted in Figure 2-8, the roundabout will have one main lane in the circle with one lane approach from Arch Street, Dockweiler Drive and 12th Street. At the roundabout, Arch Street will accommodate right turning movements to the east and west legs of 12th Street and through access to Dockweiler Drive. Dockweiler Drive will accommodate left (southbound) and right (northbound) turning movements to Placerita Canyon Road at the offset signalized T-intersection. Placenta Canyon Road (westbound) will accommodate right turning movements to Dockweiler Drive. Dockweiler Drive Extension The Modified Project would also include the extension of the Dockweiler Drive roadway. The extension would be constructed to full Secondary Highway Pavement width (92 feet), from Aden Avenue to west of Valle Del Oro, and would provide two lanes eastbound (uphill) and two lanes westbound (downhill). The extension will be striped for one lane westbound with a buffered bike lane in interim condition. Class II bike lanes, multiuse path and pedestrian sidewalks would be provided to enhance non -auto travel safety and promote connectivity between The Master's University, the Newhall Metrolink Station and Old Town Newhall (see Figure 2-9). Additionally, as shown in Figure 2-10, the Modified Project would include a bicycle and pedestrian pathway and bridge south of Dockweiler Drive, that spans Newhall Creek, to connect with the northwest end of the Newhall Metrolink Station parking lot, located to the south of the proposed Dockweiler Drive extension.

Project Description SCH No. 2013082016 Page 2-9 City of Santa Clarita May 2021 Infrastructure Improvements As shown in Figure 2-6 Modified Project Site Plan the Modified Project would include the addition of two basins for stormwater capture and treatment; one interim detention basin would be located to the north of 13th Street and east of Railroad Avenue (see Figure 2-7) and one infiltration basin would be located south of the improvements at Placenta Canyon Road and east of the proposed Dockweiler Drive Alignment (see Figure 2-8). The stormwater basins would capture and treat stormwater runoff associated with the roadway improvements in accordance with the National Pollutant Discharge Elimination System (NPDES) requirements and City grading regulations. Additionally, as shown in Figure 2-11 and Figure 2-12, the Modified Project would include the reprofiling of the UP/Metrolink railroad line, which runs parallel to Railroad Avenue and extends north (approximately 0.25 mile) from 13th Street to approximately 15th Street. This portion of the railroad track would include regrading within the existing UP/Metrolink track right-of-way to connect to the profile and intersection improvements at 13th Street and Railroad Avenue.

S G� 4 ■ L3 rx Project Limits / Master's Property Line PARKER a Properties 2-13 ENVIRONMENTAL CONSULTANTS Adjacent Properties Map City of Santa Clarita May 2021 Construction and Grading Construction of the Modified Project would occur over an approximate 18-month timeframe and would involve clearing, grading, excavation, trenching, and asphalt paving. Construction is anticipated to begin in the spring of 2022 with operation beginning in 2025. Construction would require approximately 148,000 cubic yards (cy) of cut and 25,000 cy of fill. Approximately 123,000 cubic yards of soil export would be hauled to The Master's University Expansion Project Site to recycle and use as base material for the extension of the Dockweiler Drive roadway alignment from The Master's University limits on the west to the Valle Del Oro to the east. The Project Site is approximately 15 acres in size, and it is assumed that a maximum of approximately seven acres would be disturbed on a daily basis during the development of the Modified Project. Construction of the Modified Project would occur during four different phases as described below: • Phase 1 (9 months): Construction of the widening of 13th Street and Arch Street; and Dockweiler Drive, east of Placenta Canyon Road, to the Master's University's portion of Dockweiler Drive • Phase 2 (4 months): Construction of 12th Street Roundabout • Phase 3 (3 months): Reconstruction of existing 13th Street and Arch Street • Phase 4 (2 months): Whole corridor landscaping, street lighting, signing and striping The limits of grading for the Modified Project are illustrated in Figure 2-6 through Figure 2-12. The southeastern grading limits for the Modified Project (between Arch Street and The Master's University project limits) are generally within the grading limits that were analyzed for both the Original Project and the Approved Project. Unlike the Original Project, the Modified Project would not include the roadway extension of Lyons Avenue from Railroad Avenue to the proposed Dockweiler Drive extension, which would span a portion of Newhall Creek. The Modified Project would include a bicycle and pedestrian path that extends from the proposed Dockweiler Drive extension to the Newhall Metrolink Station to the south, which spans a smaller footprint of the Newhall Creek. The Modified Project would include a larger grading footprint on the northern portion of the Project Site (approximately seven acres), as compared to the Original Project and Approved Project, to accommodate the roadway improvements at Arch Street, 13th Street and Placerita Canyon Road, the intersection improvements at 13th Street and Railroad Avenue, grading improvements along the UP/Metrolink Railroad line north of Railroad Avenue, and the addition of two new stormwater treatment basins and associated stormwater drainage improvements. Construction of the Modified Project would require the addition of a temporary roadway along 13th Street between Railroad Avenue and Arch Street. The temporary roadway would provide a detour for vehicles during construction of the roadway improvements to 13th Street. The temporary roadway would be located on the north side of 13th Street and run parallel to 13th Street. The temporary roadway would be located within the Modified Project's grading limits. Lyons Avenue/Dockweiler Drive Extension Project Addendum 2. Project Description SCH No. 2013082016 Page 2-20 City of Santa Clarita May 2021 2.7 PROJECT OBJECTIVES The purpose of the Original Project is to achieve CPUC approval of an at -grade rail crossing at the current terminus of Lyons Avenue and the Southern Pacific Railroad line and extend a through roadway connection from Lyons Avenue to Dockweiler Drive. The City's stated objectives for the Project are as follows: • Implementation of the goals of the Circulation Element of the Santa Clarita General Plan, including the crossing at Lyons Avenue and the extension of Lyons Avenue/Dockweiler Drive; • Improve roadway level of service and circulation network; • Provide a safe and efficient at -grade rail crossing that meets the standards of the California Public Utilities Commission (CPUC); • Provide sufficient information for CPUC application and approval of the proposed crossing; • Improve pedestrian and vehicle railroad safety by eliminating an existing substandard at -grade rail crossing at 13th Street and replacing it with a more advanced and enhanced at -grade rail crossing at Lyons Avenue; • Reduce vehicle miles traveled by creating a more direct route for motorists, eliminating circuitous driving patterns. • Provide greater connectivity between Old Town Newhall, Placerita Canyon, The Master's University and the residents that live along Dockweiler Drive; • Provide an economic stimulus to Old Town Newhall with enhanced connectivity to the Old Town Newhall area; and • Provide an enhanced gateway to Placenta Canyon. Like the Original Project and Approved Project, the Modified Project would remain consistent with the objectives identified in the EIR. The Modified Project would be consistent with the City's Circulation Element as an additional route of travel connecting Railroad Avenue to Dockweiler Drive. The Modified Project would include upgrades to the at -grade railroad crossing at the intersection of Railroad Avenue and 13th Street, including new turn lanes, roadway widening, and median improvements. The Modified Project would also introduce a roundabout at the 12th Street/ Arch Street/ Dockweiler Drive intersection and modify the roadway connection from Dockweiler Drive to Placenta Canyon Road. These roadway improvements would improve traffic operations and enhance the safety of pedestrians and bicyclists. Additionally, the extension of Dockweiler Drive would promote non -auto travel by including bicycle and pedestrian pathways along Dockweiler Drive and south of Dockweiler Drive that spans Newhall Creek, to connect with the northwest end of the Newhall Metrolink Station parking lot, located to the south of the proposed Dockweiler Drive roadway extension. These improvements would provide connectivity from, Old Town Newhall and the Metrolink Station to The Master's University. Lyons Avenue/Dockweiler Drive Extension Project Addendum 2. Project Description SCH No. 2013082016 Page 2-21 City of Santa Clarita May 2021 2.8 DISCRETIONARY ACTIONS Lead Agency The City of Santa Clarita is the Lead Agency as set forth in CEQA Guidelines §21067 and is responsible for reviewing and approving this EIR Addendum to the Original Project's Final EIR based on the City's independent judgement. Like the Approved Project, the Modified Project would also require the approval of an Oak Tree Permit and Hillside Review Permit at such time as development occurs or when funding of roadway construction becomes available. The Oak Tree Permit would be required to determine the oak tree impacts at the time of project development. The Hillside Review Permit would permit the grading necessary to construct the roadway. Additional discretionary actions include acquisition of right-of-way and awarding of a contract for construction of the roadway. Additional ministerial actions, such as grading permits, would be required by the City prior to actual grading and construction of the proposed roadway extension. Responsible Agencies Public agencies other than the Lead Agency, that have discretionary approval power or regulatory oversight over the proposed project or project activities are considered "Responsible Agencies" (State CEQA Guidelines Section 15381). If the City approves the Proposed Project, subsequent implementation of various project components could require discretionary approval authority from the following responsible agencies: • California Public Utilities Commission (CPUC); • Southern California Rail Authority; • Los Angeles County Metropolitan Transportation Authority (LACMTA); • California Department of Fish and Wildlife (CDFW); • California Regional Water Quality Control Board (RWQCB); • Los Angeles County Fire Department (LACFD): • Los Angeles County Department of Public Works (LAPW) • South Coast Air Quality Management District (SCAQMD); • U.S. Fish and Wildlife Service (USFWS); and • U.S. Army Corps of Engineers (USACE).

Environmental Determination SCH No. 2013082016 Page 3-1 [Page left intentionally blank.] 4.0 ENVIRONMENTAL IMPACT ANALYSIS This section contains a summary of the Approved Project's impacts, as presented in the EIR (see Section 6.4 Alternative 2 of the EIR), and an assessment of the Modified Project's impacts associated with the environmental issues and subject areas identified in the Initial Study Checklist (Appendix G to the State CEQA Guidelines, (C.C.R. Title 14, Chapter 3, 15000-15387), as amended on January 1, 2019. Section 4.5 Energy, Section 4.11 Tribal Cultural Resources and Section 4.12 Wildfire, have been included below in this Addendum to be consistent with the amended CEQA Guidelines. The Modified Project's impacts are then compared to the impacts and level of significance identified for the Approved Project and in some instances where applicable the Original Project. 4.1 AESTHETICS Approved Project Temporary Construction Impacts Under the Approved Project, the existing visual character of the Project Site would be adversely impacted throughout the duration of the construction period. Impacts related to aesthetic character of the area during construction would be considered significant but temporary. Implementation of Mitigation Measure 4.1-1, which would require the screening of construction equipment, would reduce impacts to less than significant. Long Term Operational Impacts Under the Approved Project, the Dockweiler Drive roadway extension would be developed in accordance with the City's roadway standards and design guidelines to ensure the graded hillsides, medians, and walkways are landscaped in a manner that maintains the visual aesthetic quality and character of the City's roadway infrastructure. Implementation of Mitigation Measure 4.1-2 would ensure that the roadway median and contoured slopes of the roadway alignment would be landscaped and maintained. Therefore, impacts related to long-term operation would be less than significant. Alteration ofA Significant Ridgeline As concluded in the Final EIR, construction of the proposed roadway alignment between Dockweiler Drive and Arch Street would permanently alter a significant ridgeline as designated in the City of Santa Clarita General Plan .2 As a project design feature the Approved Project's grading plan would incorporate landform grading practices to blend the manufactured slopes and required drainage benches into the natural 2 As noted in Section 4.1, Aesthetics, of the EIR, the eastern segment of the Dockweiler alignment was previously approved under a separate project entitlement for The Master's University in 2009, which included a Ridgeline Alteration Permit for the eastern segment of this ridgeline. As part of the approved entitlements for The Master's University Master Plan in 2009, the irreversible grading and re -contouring of the ridgeline was approved to the western limit of The Master's University Campus. Lyons Avenue/Dockweiler Drive Extension Project Addendum 4. Environmental Impact Analysis SCH No. 2013082016 Page 4-1 City of Santa Clarita May 2021 topography to the maximum extent feasible. Plant materials would be utilized to protect slopes from slippage and soil erosion and minimize the visual effects of grading and construction on a hillside area. As concluded in the EIR, with approval of a Hillside Review Permit, aesthetic impacts associated with the grading of the Approved Project would be reduced to less than significant levels. Visual Character The Approved Project would include pedestrian and bicycle improvements to Dockweiler Drive. These project features would increase accessibility to scenic natural resources including the Newhall Creek and surrounding ndgelines and mountains. Therefore, impacts related to visual character would be the less than significant. Roadway Light and Glare The Approved Project would introduce nighttime lighting to the vicinity, which would include pole - mounted streetlights at intersections and lighted bollards along Dockweiler Drive and would contribute to additional light and glare from the headlights of vehicles utilizing the roadway. Although, the Approved Project would be expected to slightly increase ambient lighting in the area, compliance with the design standards and requirements established in the Santa Clarita Municipal Code Section 17.51.050 would mitigate lighting impacts to a less than significant level. Therefore, impacts related to roadway light and glare would be less than significant. Modified Project Temporary Construction Impacts Similar to the Approved Project, the existing visual character of the Project Site would be adversely impacted throughout the duration of the construction period under the Modified Project. The Modified Project would include a larger grading footprint on the northern portion of the Project Site (approximately seven acres), as compared to the Approved Project, to accommodate the roadway improvements at Arch Street, 13th Street and Placerita Canyon Road, the intersection improvements at 13th Street and Railroad Avenue, grading improvements along the UP/Metrolink Railroad line, and the addition of two new stormwater treatment basins. Grading, temporary storage of building materials and use of construction equipment could occupy the field of view of passing motorists, pedestrians and nearby residents. The construction site would continue to be visible from the residential properties on Aden Avenue and from passing motorists on Lyons Avenue, Railroad Avenue, Market and Race Streets, and at the Arch Street/12th Street/Placenta Canyon intersection. The Modified Project would also include a temporary roadway detour on the north side of 13th Street to provide access between Arch Street and Railroad Avenue to allow for construction on 13th Street. Like the Approved Project, impacts related to aesthetic character of the area during construction under the Modified Project would be considered significant but temporary. Like the Approved Project, the Modified Project would implement Mitigation Measure 4.1-1, which would require the screening of construction equipment, which would reduce impacts to less than significant. Therefore, Lyons Avenue/Dockweiler Drive Extension Project Addendum 4. Environmental Impact Analysis SCH No. 2013082016 Page 4-2 City of Santa Clarita May 2021 impacts related to aesthetic character of the area during construction would be comparable to impacts identified under the Approved Project. Long Term Operational Impacts Underthe Modified Project, the aesthetic character of the Project Site and its immediate surroundings would be permanently altered to generally the same degree as that which would occur under the Approved Project. Views of the hillside on the southeast portion of the Project Site (between Arch Street and Dockweiler Drive at The Master's University project limits) would be similarly altered by grading for the proposed Dockweiler Drive roadway extension as the grading limits of the Modified Project are largely within the grading limits of the Approved Project. Views of the Project Site at the intersection of Railroad Avenue and 13th Street would be similar to existing views of the intersection, as the Modified Project also includes the improvement of the at -grade railroad crossing. Views of the intersection of the Arch Street/12tn Street/Placenta Canyon intersection would be altered to include the four-way legged roundabout intersection. The Modified Project would also include a pedestrian and bicycle pathway that would span Newhall Creek, reprofiling of the UP/Metrolink railroad track between 13th Street and 15th Street, and the addition of two stormwater treatment basins. Like the Approved Project, implementation of Mitigation Measure 4.1-2, would ensure that the proposed roadway median and contoured slopes of the roadway alignment under the Modified Project would be landscaped and maintained in accordance with the City's roadway standards and design guidelines. Overall, impacts related to long-term operation would remain less than significant and would not result in more severe or new impacts as those identified under the Approved Project. Loss of Oak Trees As shown in the Oak Tree Inventory (see Appendix B of this Addendum), construction of the Modified Project would result in the encroachment of eight oak trees within the immediate vicinity of Modified Project's grading limits and require the removal of four oak trees within the Modified Project's grading limits. As concluded under the Approved Project, the removal or encroachment of oak trees as a result of project construction would be considered a significant impact under both the City of Santa Clanta and CEQA. Replacement oak trees would be planted in the number necessary to comply with the requirements stipulated in the Oak Tree Permit issued by the City. Although the Modified Project would result in the encroachment and removal of additional oak trees, as compared to the Approved Project, with approval of the required oak tree permits, and implementation of Mitigation Measure 4.3-7 in Section 4.3, Biological Resources, aesthetic impacts associated with the loss or pruning of any oak tree would be reduced to less than significant levels. Therefore, under of the Modified Project, impacts related to oak trees would be marginally higher but would remain less than significant with mitigation. Lyons Avenue/Dockweiler Drive Extension Project Addendum 4. Environmental Impact Analysis SCH No. 2013082016 Page 4-3 City of Santa Clarita May 2021 Alteration ofA Significant Ridgeline Similar to the Approved Project, construction of the Modified Project would include the roadway alignment between Dockweiler Drive at The Master's University project limits and Arch Street. The hillside on the southeast portion of the Project Site would be similarly altered by grading for the proposed roadway extension as the grading limits of the Modified Project are largely within the grading limits of the Approved Project. Like the Approved Project, the Modified Project would also incorporate landform grading practices and plant materials as a Project Design Feature to protect slopes from slippage and soil erosion and minimize the visual effects of grading and construction on a hillside area. Similarly, the Modified Project would require approval of a Hillside Review Permit. As such aesthetic impacts associated with the grading of the Modified Project would be reduced to less than significant levels and impacts would be similar to that of the Approved Project. Visual Character Similar to the Approved Project the Modified Project also includes pedestrian and bicycle improvements to Dockweiler Drive that would include wide sidewalks and Class II bike lanes on each side. These project features would increase accessibility to scenic natural resources including the Newhall Creek and surrounding ndgelines and mountains. Additionally, as shown in Figure 2-10 Modified Project Bike Path, the Modified Project would include a bicycle and pedestrian pathway south of Dockweiler Drive, that spans Newhall Creek, to connect with the northwest end of the Newhall Metrolink Station parking lot, located to the south of the proposed Dockweiler Drive extension. Therefore, impacts related to visual character would be the less than significant and impacts would be similar to that of the Approved Project. Roadway Light and Glare The Modified Project would be expected to slightly increase ambient lighting in the area in the same manner as the Approved Project. Lighting uses associated with the Modified Project are not anticipated to substantially impact any surrounding sensitive uses as the streetlights would be installed with downward directional fixtures and would not create light trespass onto any adjacent properties. Light emanating from the Modified Project would be a relatively low-level indirect source of light illuminating the roadway and pedestrian walkways and would not adversely impact other properties in the immediate area. Additionally, the steep terrain and orientation of the southeastern portion of the Project Site would shield vehicle headlights, signage lighting and streetlights from impacting the residential properties within the Placenta Canyon community to the east and along Market and Race Streets to the west. Similarly, compliance with the design standards and requirements established in the Santa Clanta Municipal Code Section 17.51.050 would mitigate lighting impacts to a less than significant level. Therefore, impacts related to roadway light and glare would be the same as those identified under the Approved Project. Lyons Avenue/Dockweiler Drive Extension Project Addendum 4. Environmental Impact Analysis SCH No. 2013082016 Page 4-4 City of Santa Clarita May 2021 4.2 AIR QUALITY Approved Project Construction As discussed in the EIR construction of the Original Project would occur over an approximate 12-month timeframe and would involve clearing, grading, excavation, trenching, and asphalt paving. Construction would require 4,990 cubic yards (cy) of cut, 2,760 cy of fill, and 2,230 cy of soil export associated with grading and excavation. During construction, on -site stationary sources, heavy-duty construction vehicles, construction worker vehicles, and energy use would generate emissions. Additionally, grading, excavation, and other construction activities on the Project Site would generate fugitive dust emissions. Construction activities and their associated air quality impacts would be short-term in nature and limited only to the period when construction activity is actively taking place on the Project Site. The Project Site under the Original Project would be approximately 5 acres in size and consists of natural land area. For purposes of the analysis it was assumed that a maximum of approximately 2 acres would be disturbed on a daily basis during the development of the Proposed Project. Clearing and grubbing of the area was expected to begin in December of 2019 and last through the end of 2020. Like the Original Project, construction of the Approved Project would occur over an approximately 12- month timeframe and would involve clearing, grading, excavation, trenching, and asphalt paving. As discussed in the EIR, the Approved Project's construction emissions would be similar to the emissions generated under the Original Project (see Section 4.2 Air Quality and Section 6.4 Alternative 2, of the EIR) but slightly reduced as the Approved Project would involve less mass grading. The increased emissions associated with the Arch Street to 13th Street improvements would be offset by the avoidance of grading associated with the Dockweiler to Lyons connection. As the Original Project emissions would be below South Coast Air Quality Managements District's (SCAQMD's) significance thresholds for all criteria pollutants, the Approved Project's regional construction air quality emissions would also be less than significant. AQMP Consistency Like the Original Project, the Approved Project would not exceed the AQMD's significance thresholds for regional construction emissions and thus would not increase the frequency or severity of existing air quality violations or cause or contribute to new air quality violations within the Basin. The Approved Project is consistent with the AQMP and would not interfere with attainment of air quality levels identified in the AQMP. The Approved Project would help reduce congestion and vehicles per miles travelled by providing sidewalks and bicycle lanes and by providing direct access from the residential area and The Master's University area to the Jan Heidt Newhall Metrolink Station and Old Town Newhall. The Approved Project encourages alternative modes of transportation other than motor vehicles and would be consistent with the goals and objectives of the AQMP to reduce vehicle emissions throughout the Basin. Lyons Avenue/Dockweiler Drive Extension Project Addendum 4. Environmental Impact Analysis SCH No. 2013082016 Page 4-5 City of Santa Clarita May 2021 Localized Construction Emissions Like the Original Project, the EIR concluded that the Approved Project would result insignificant localized air emissions inclose proximity to residential land uses within 100 meters of the Project Site on a temporary and intermittent basis during construction. Localized NO,, and CO emissions would be below the significance thresholds at all sensitive receptor locations. However, localized thresholds would be exceeded for PM,o and PM2.5 emissions at two locations: (1) the single-family residential land uses located immediately north of the Project Site (within a proximity of 100 meters) and (2) the residential land uses within 100 meters south of the Project Site in the vicinity of Market Street and Race Street (see Section 4.2 Air Quality, Table 4.2-10, of the EIR). Localized emissions would be below the stated thresholds for any land use located further than 100 meters from the Project Site. Therefore, notwithstanding implementation of Mitigation Measures 4.2-1 through 4.2-4, which require best management practices to minimize construction -related emissions, localized air quality impacts resulting from construction activities would be considered significant and unavoidable. Operational Emissions A CO hotspot analysis was conducted for the Original Project, which includes the roadway extension of Lyons Avenue to Dockweiler Drive and the closure of the railroad crossing and vehicular access at the intersection of 13th and Railroad Avenue. As discussed in Section 4.2 Air Quality, of the EIR, modeling of future CO concentrations from the intersections in the study area was based on projected traffic volumes from the intersections contained in the Original Project Traffic Study'. Interim year 2019 with -project conditions CO concentrations were calculated for peak hour traffic volumes for those intersections that are anticipated to operate at LOS D or worse, based on the traffic analysis for the Project (see Section 4.9, Transportation and Traffic of the EIR). Background (existing) ambient CO concentrations were also factored into the analysis. The results of these CO Hotspot concentration calculations are presented in Section 4.2 Air Quality, Table 4.2-11, Existing Conditions Plus Project (2019) Carbon Monoxide Concentrations, of the EIR. As shown in Table 4.2-11, the screening calculations predict that, under worst - case conditions, future CO concentrations at each intersection would not exceed the state 1-hour and 8-hour standards with or without the development of the Original Project. Although the Approved Project would not directly generate any new vehicle trips, it would result in changes to the traffic circulation in the vicinity and would alter the average daily traffic volumes and peak hour traffic volumes at local intersections. As the Approved Project is within the same envelope as the Original Project, it was found that, under worst -case conditions, future CO concentrations at each intersection would not exceed the state 1-hour and 8-hour standards with or without the development of the Project. Therefore, no significant project -related impact would occur relative to future carbon monoxide concentrations of the 3 Traffic Impact Analysis: Dockweiler Drive Alignment Project, Santa Clarita, CA, prepared by David Evans and Associates, dated August 8, 2017. See Appendix H of the Final EIR. Lyons Avenue/Dockweiler Drive Extension Project Addendum 4. Environmental Impact Analysis SCH No. 2013082016 Page 4-6 City of Santa Clarita May 2021 Approved Project. The Approved Project would have a less than significant impact with respect to this criterion. Modified Project Construction Construction of the Modified Project would be slightly different as compared to the Approved Project as the Modified Project would occur over an approximate 18-month timeframe during four different phases as described below: • Phase 1 (9 months): Construction of the widening of 13th Street and Arch Street; and Dockweiler Drive, east of Placenta Canyon Road, to the Master's University's portion of Dockweiler Drive; • Phase 2 (4 months): Construction of 12th Street Roundabout • Phase 3 (3 months): Reconstruction of existing 13th Street and Arch Street • Phase 4 (2 months): Whole corridor landscaping, street lighting, signing and striping Construction of the Modified Project would involve site clearing, grading, excavation, trenching, and asphalt paving, and utility relocation. Construction would require a total of 148,000 cubic yards (cy) of cut/export and 25,000 cy of fill associated with grading and excavation. Approximately 123,000 cubic yards of export would be hauled to The Master's University to recycle and use as base material. During construction, on -site stationary sources, heavy-duty construction vehicles, construction worker vehicles, and energy use would generate emissions. Additionally, grading, excavation, and other construction activities on the Project Site would generate fugitive dust emissions. Construction activities and their associated air quality impacts would be short-term in nature and limited only to the period when construction activity is actively taking place on the Project Site. The entire Project Site is approximately 15 acres in size and consists of natural land area. For purposes of this analysis, it is assumed that a maximum of approximately 7 acres would be disturbed on a daily basis during the development of the Proposed Project. As discussed above, construction of the Modified Project would occur over an approximately 18-month timeframe during four different phases and would involve clearing, grading, excavation, trenching, and asphalt paving. Construction is anticipated to begin in the spring of 2022 with operation beginning in 2025. Sources of emissions during construction include stationary and mobile uses of construction equipment, construction vehicles (heavy-duty construction vehicles and worker vehicles), and energy use. As shown in Table 4-1, the Modified Project's construction emissions would be higher than the emissions generated under the Original Project (see Section 4.2 Air Quality) since the Modified Project would involve more mass grading activity and anticipates a longer construction schedule. The increased emissions associated with the Arch Street to 13th Street improvements would be offset by the avoidance of grading associated with the Dockweiler to Lyons connection. Additionally, a majority of the anticipated soil export would be hauled to Master's University, which would reduce the amount of fugitive dust and diesel emissions, compared to soil export that would typically be hauled to a disposal site much farther away from the Project Lyons Avenue/Dockweiler Drive Extension Project Addendum 4. Environmental Impact Analysis SCH No. 2013082016 Page 4-7 City of Santa Clarita May 2021 Site. As the Original Project emissions would be below South Coast Air Quality Managements District's (SCAQMD's) significance thresholds for all criteria pollutants, the Modified Project's regional construction air quality emissions would remain less than significant and no new impacts or severity in impacts would occur.

Environmental Impact Analysis SCH No. 2013082016 Page 4-8 City of Santa Clarita May 2021 AQMP Consistency The Modified Project would not exceed the AQMD's significance thresholds for regional construction emissions and thus would not increase the frequency or severity of existing air quality violations or cause or contribute to new air quality violations within the Basin. Like the Approved Project, the Modified Project would also be consistent with the AQMP and would not interfere with attainment of air quality levels identified in the AQMP. The Modified Project would help reduce congestion and vehicles per miles traveled by providing sidewalks and bicycle lanes and by providing direct non -auto travel access from the residential area and Master's University area to the Jan Heidt Newhall Metrolink Station and Old Town Newhall. The Modified Project encourages alternative modes of transportation other than motor vehicles and would be consistent with the goals and objectives of the AQMP to reduce vehicle emissions throughout the Basin. Localized Construction Emissions Like the Approved Project, the Modified Project would also result in significant localized air emissions in close proximity to residential and institutional land uses within 100 meters of the Project Site on atemporary and intermittent basis during construction. Three additional sensitive receptors were identified that would be impacted by localized emissions from the Modified Project construction: residential uses at Newhall Crossings, residential uses fronting Walnut Street and Newhall Avenue, and the mobile homes fronting Railroad Avenue (added as Sensitive Receptor 5 to 7 in Table 4-2, below). See Figure 4-1, Air Quality Sensitive Receptor Map, for all identified sensitive receptors within 0.25-mile of the Modified Project's construction. As mentioned previously, the entire Project Site is approximately 15 acres in size, and it is assumed that a maximum of approximately 7 acres would be disturbed on a daily basis during the development of the Modified Project. As such, under this scenario, the localized air quality impacts were then compared to the SCAQMD's localized significance thresholds screening criteria for a 5-acre site as a conservative estimate. The Modified Project's localized construction emissions would be higher than the emissions generated under the Original Project, since the Modified Project would involve more mass grading activity and anticipates a longer construction schedule. As shown in Table 4-1, below, localized NO,, and CO emissions would be below the significance thresholds at all sensitive receptor locations. However, localized thresholds would be exceeded for PM,o and PM2.5 emissions at all residential sensitive receptor locations within a proximity of 200 meters. Localized emissions would be below the stated thresholds for any land use located further than 200 meters from the Project Site. Therefore, notwithstanding implementation of Mitigation Measures 4.2-1 through 4.2-4, which require best management practices to minimize construction -related emissions, localized air quality impacts resulting from construction activities would be considered significant and unavoidable, similar to the Approved Project.

The analysis of localized air quality impacts associated with NOx emissions is focused on NOz levels as they are associated with adverse health effects. Distances from the Project Site to the sensitive receptors are expressed in meters. Calculation sheets are provided in Appendix A to this Addendum. Operational Emissions Although the Modified Project would not directly generate any new vehicle trips, the Project would result in changes to the traffic circulation in the vicinity and would alter the average daily traffic volumes and peak hour traffic volumes at local intersections, similar to the Approved Project and Original Project. As discussed above under the Approved Project, a CO hotspot analysis was conducted for the Original Project. Modeling of future CO concentrations from the intersections in the study area was based on projected traffic volumes from the intersections contained in the Original Project Traffic Study4. With respect to roadway improvements, the Modified Project includes the extension of Dockweiler Drive to Arch Street, as well as the installation of a roundabout at the intersection of the Arch Street/12th 4 Ibid. Lyons Avenue/Dockweiler Drive Extension Project Addendum 4. Environmental Impact Analysis SCH No. 2013082016 Page 4-10 City of Santa Clarita May 2021 Street/Placenta Canyon intersection. As discussed further below in Section 4.10 Transportation, the traffic volumes for the Modified Project's Traffic Study (see Appendix D of the Addendum) were based on results of the Traffic Impact Study for the EIR and its assumptions for traffic forecast modeling. Based on updated modeling for the project area with respect to traffic distribution and the Modified Project's roadway configurations at the Arch Street/12th Street/Placenta Canyon intersection, traffic volume actually decreased on the roadway segments between Railroad Avenue and 13th Street and 12th Street and Dockweiler Drive under the 2035 horizon year project scenarios, as compared to the Approved Project. As no new significant vehicle delays were identified with respect to the Modified Project's roundabout configuration at the Arch Street/ 12th Street/Placerita Canyon intersection 6, and the extension of Dockweiler Drive between Arch Street and The Master's University project site limits are largely within the footprint that was analyzed under the Original Project, no significant project -related impact would occur relative to future carbon monoxide concentrations of the Modified Project. Therefore, similar to the Approved Project, the Modified Project would have a less than significant impact with respect to operational air quality emissions. 5 As discussed in the Traffic Study (see Appendix D), a project year of 2025 was identified as the opening year for the Modified Project. Traffic volumes for year 2025 were calculated by interpolation between the EIR Alternative 2 Year 2019 and Year 2035 traffic volumes. 6 The Traffic Study (see Appendix D) notes that based upon the proposed intersection alternatives and discussion with the City ofSanta Clarita, it was determined that comparing Level ofService (LOS) would not be appropriate, as roundabouts and standard intersections operate differently. Therefore, Vehicle Queue Lengths and Vehicle Delay at the approaches of the Dockweiler Drive/12' Street/Placenta Canyon Road study intersection would be estimated to determine how the project performs.

Environmental Impact Analysis SCH No. 2013082016 Page 4-11 City of Santa Clarita May 2021 4.3 BIOLOGICAL RESOURCES Approved Project Habitat Modification Vegetation The Final EIR concluded that of the vegetation communities impacted by the Approved Project, Disturbed California Sagebrush -California Buckwheat Scrub would be the dominant plant community present by area and approximately less than 0.63 acre of this habitat would be lost through site grading and project implementation. Due to the Project Site's disturbance history, its small size, the lack of sensitive plant communities, the lack of structure for wildlife, and high percentage of invasive and non-native plant species generally associated with disturbed areas, impacts associated with the loss of less than 2 acres of vegetation present on -site is considered less than significant. The only special -status plants observed during the field investigation were two coast live oaks. No other special -status plants are considered to have a high potential for occurrence within the Project Site. With implementation of Mitigation Measure 4.3-7, which would ensure compliance with the City's Oak Tree Preservation and Protection Guidelines, impacts would be mitigated to less than significant. ii. Wildlife Project -related activities associated with site preparation and construction of the Approved Project could result in the direct loss of individuals of one special -status wildlife species (the silvery legless lizard) and of active nests or the abandonment of active nests by adult birds should grading occur during nesting season. The loss of a California species of special concern and active bird nests would be a considered significant without mitigation. However, implementation of Mitigation Measures 4.3-1 and 4.3-2 would reduce impacts to the silvery legless lizard and nesting birds to a less than significant level. Federally Protected Wetlands The Approved Project would not result in either temporary or permanent impacts to the areas of the Newhall Creek and its associated tributary. The Approved Project does not include the extension of Lyons Avenue to Dockweiler Drive, which would span a portion of the Newhall Creek. As such no impacts to jurisdictional resources would occur. Wildlife Movement and Corridors The Project Site is generally surrounded on three sides by development and road networks. Although the Newhall Creek is located to the west of the Project Site, the Approved Project would not result in any barrier to wildlife movement and would not impede the ability of Newhall Creek to function as a wildlife movement corridor. The Approved Project would not result in significant impacts to wildlife movement. Lyons Avenue/Dockweiler Drive Extension Project Addendum 4. Environmental Impact Analysis SCH No. 2013082016 Page 4-13 City of Santa Clarita May 2021 Construction Activity Construction -related activities, particularly site clearing, grading, and the implementation of the road surface, could have adverse effects on plant and wildlife habitat, and together, would be considered a significant impact. Implementation of Mitigation Measure 4.3-4, which specifies guidelines to minimize impacts on remaining biological resources on the site as a result of construction and grading activities, would reduce these construction -related impacts to a less than significant level. Operation Increase in Populations of Non -Native Species Historical and ongoing development in the vicinity of the Project Site has already supported continual and ongoing increase and proliferation of non-native plant and wildlife species in the vicinity of the Project Site. Development of the Approved Project is not expected to substantially increase the distribution of non- native plants and wildlife. Compliance with Mitigation Measure 4.3-5, which requires provisions to avoid the use of, or growth of, invasive plant species, would reduce impacts to a less than significant level. ii. Increased Light and Glare As concluded in the Final EIR, it is anticipated that nighttime lighting would increase in areas adjacent to the Project Site, which can disturb breeding and foraging behavior, movement, and can potentially alter breeding cycles of birds, mammals, and nocturnal invertebrates. The Approved Project would increase light and glare effects near to the Newhall Creek corridor. Implementation of Mitigation Measure 4.3-6 would require that lighting is directed away from natural areas, which would decrease this impact to a less than significant level. Stormwater and Urban Runoff It is expected that stormwater runoff associated with the Approved Project would be limited to pavement runoff during periodic storm events. Runoff could substantially affect special -status species potentially occurring downstream from the Project Site (i.e. Newhall Creek), incrementally diminish habitat, and degrade the quality of the environment. With the compliance to City's standard stormwater requirements and required design criteria, impacts to Newhall Creek resulting from Stormwater runoff from the Approved Project would be less than significant. Lyons Avenue/Dockweiler Drive Extension Project Addendum 4. Environmental Impact Analysis SCH No. 2013082016 Page 4-14 City of Santa Clarita May 2021 Modified Project Habitat Modification Vegetation Based on the Biological Resources Assessment prepared for the EIR, (see Appendix D of the EIR)', of the vegetation communities impacted by the Modified Project, Disturbed California Sagebrush -California Buckwheat Scrub would be the dominant plant community present within the Project Site, similar to the Approved Project. Although the Modified Project would include a larger grading footprint on the northern portion of the Project Site to accommodate grading improvements associated with the UP/Metrolink rail trail and stormwater treatment basins, as compared to the Approved Project, due to the Project Site's disturbance history, its small size, the lack of sensitive plant communities, the lack of structure for wildlife, and high percentage of invasive and non-native plant species generally associated with disturbed areas, impacts associated with the loss of the vegetation present on -site would be considered less than significant. As shown in the Oak Tree Inventory (see Appendix B of this Addendum), construction of the Modified Project may result in the encroachment of eight oak trees within the immediate vicinity of Modified Project's grading limits and require the removal of four oak trees within the Modified Project's grading limits. Although the Modified Project would result in the encroachment and removal of additional oak trees, as compared to the Approved Project, with approval of the required oak tree permits, and implementation of Mitigation Measure 4.3-7, which would ensure compliance with the City's Oak Tree Preservation and Protection Guidelines, impacts would be mitigated to less than significant. Therefore, under of the Modified Project, impacts related to vegetation would be marginally higher but would remain less than significant with mitigation, like the Approved Project. ii. Wildlife Like the Approved Project, activities associated with site preparation and construction of the Modified Project could result in the direct loss of individuals of one special -status wildlife species (the silvery legless lizard) and of active nests or the abandonment of active nests by adult birds should grading occur during nesting season. Although the Modified Project would include a larger grading footprint on the northern portion of the Project Site, as compared to the Approved Project, like the Approved Project implementation of Mitigation Measures 4.3-1 and 4.3-2 would reduce impacts to the silvery legless lizard and nesting birds to a less than significant level. Therefore, impacts associated with wildlife underthe Modified Project would be the same as those identified under the Approved Project.

A portion of this pathway would cross over Newhall Creek; however, no footings within Newhall Creek would be required. Nevertheless, the Modified Project would require implementation of Mitigation 4.3-3, which would reduce impacts to jurisdictional resources to a less than significant level. When compared to the Original Project, which includes the extension of Lyons Avenue to Dockweiler Drive, which would span a portion of Newhall Creek, the Modified Project has a smaller footprint and span with respect to Newhall Creek. While impacts under the Modified Project would be marginally higher as compared to the Approved Project, impacts would be less than those identified under the Original Project. Wildlife Movement and Corridors Like the Approved Project, the Modified Project would not result in any barrier to wildlife movement. The Modified Project would include a pedestrian/bicycle pathway and bridge that connects from the proposed Dockweiler Drive extension to the Newhall Metrolink Station to the southwest. A portion of this pathway would span the Newhall Creek; however, no footings within Newhall Creek would be required. Therefore, the Approved Project would not impede the ability of Newhall Creek to function as a wildlife movement corridor. The Modified Project would not result in significant impacts to wildlife movement. Impacts related to wildlife movement would be similar to those identified under the Approved Project. Construction Activity Like the Approved Project, construction -related activities of the Modified Project, particularly site clearing, grading, and the implementation of the road surface, could have adverse effects on plant and wildlife habitat, and together, would be considered a significant impact.

Similar to the Approved Project, runoff could substantially affect special -status species potentially occurring downstream from the Project Site (i.e. Newhall Creek), incrementally diminish habitat, and degrade the quality of the environment. The Modified Project would include two basins for stormwater capture and treatment; one interim detention would be located to the north of 13th Street and east of Railroad Avenue (see Figure 2-7 Modified Project Grading Plan at Railroad Avenue and 13th Street) and one infiltration basin would be located south of the improvements as Placenta Canyon Road and east of the proposed Dockweiler Drive Alignment (see Figure 2-8 Modified Project Grading Plan at Arch Street/ 12th Street/ Placenta Canyon Road/ Dockweiler Drive Extension Intersection). The stormwater basins would capture and treat stormwater runoff associated with the roadway improvements in accordance with the National Pollutant Discharge Elimination System (NPDES) requirements and City grading regulations. Similar to the Approved Project, compliance with the City's standard stormwater requirements and required design criteria would reduce impacts to Newhall Creek stormwater runoff impacts to a less than significant level. Impacts from stormwater runoff would be marginally less, due to the addition of the stormwater basins on the Project Site, as compared to the Approved Project.

Archaeological Resources and Human Remains No known archeological sites are identified within the Project Site for the Approved Project. However, construction -related earthwork activities may result in the accidental discovery of prehistoric or historic archaeological resources or Native American burial sites. Implementation of Mitigation Measures 4.4-1, which would ensure the preservation, conservation, or relocation in the event any resources are discovered during construction -related earthwork activities, would reduce impacts to a less than significant level. Modified Project Cultural and Historic Resources Like the Approved Project, no cultural or historic habitable structures are located on the Project Site, and as such, the Modified Project would not have the potential to adversely impact any historic or cultural resources. Project impacts associated with historic and cultural resources would therefore be the same under the Modified Project as that which was analyzed under the Approved Project. Archaeological Resources and Human Remains The southeastern grading limits for the Modified Project (between Arch Street and The Master's University project limits) are generally within the grading limits that were analyzed for both the Original Project and the Approved Project. The Modified Project would include a larger grading footprint on the northern portion of the Project Site (approximately seven acres), as compared to the Original Project and Approved Project, to accommodate the roadway improvements at Arch Street, 13th Street and Placerita Canyon Road, the intersection improvements at 13th Street and Railroad Avenue, grading improvements along the UP/Metrolink railroad line between 13th Street and 15th Street, and the addition of two new stormwater basins. Similar to the Approved Project, construction -related earthwork activities may result in the accidental discovery of prehistoric or historic archaeological resources or Native American burial sites. Like the Approved Project implementation of Mitigation Measures 4.4-1 would ensure the preservation, conservation, or relocation in the event any resources are discovered during construction -related earthwork activities, would reduce impacts to a less than significant level. Impacts under the Modified Project would therefore be similar to those identified under the Approved Project. Lyons Avenue/Dockweiler Drive Extension Project Addendum 4. Environmental Impact Analysis SCH No. 2013082016 Page 4-18 City of Santa Clarita May 2021 4.5 ENERGY Approved Project Subsequent to the adoption of the EIR, the State CEQA Guidelines have been amended to require lead agencies to determine a project's demand on electricity, natural gas, and transportation energy. This section analyzes the Modified Project's impacts to energy conservation and resources. Modified Project In accordance with guidance provided in Appendix G to the state CEQA Guidelines, the Modified Project would have a significant impact on energy if it would: (a) Result in potentially significant environmental impact due to wasteful, inefficient, or unnecessary consumption of energy resources, during project construction or operation; (b) Conflict with or obstruct a state or local plan for renewable energy or energy efficiency; Impact Analysis a) Would the Project result in potentially significant environmental impact due to wasteful, inefficient, or unnecessary consumption of energy resources, during project construction or operation? A significant impact would occur if the Modified Project results in potentially significant environmental impacts due to wasteful, inefficient, or unnecessary consumption of energy resources, during project construction or operation. Construction Energy would be consumed during the grubbing/land clearing, grading/excavation, drainage/utilities/sub- grade, and paving phases of the Modified Project for grading and materials transfer by heavy-duty equipment, which is usually diesel powered. Construction of the Modified Project would generate an increased demand for electricity use related to the treatment and conveyance of water for dust suppression activities during the excavation and grading phase, and the consumption of gasoline and diesel fuels associated with haul trucks, deliveries, and worker commute trips. However, due to the relatively short duration of the construction process, and the fact that the extent of fuel consumption is inherent to construction projects of this size and nature, fuel consumption impacts would not be considered excessive or substantial with respect to regional fuel supplies. Further, compliance with regulatory compliance measures, such as restricting haul trucks to off-peak hours and not allowing engines to idle excessively when not in use (AQMD Rule 403), and meeting specified fuel and fuel additive requirements and emission standards (C.C.R. Title 13, Sec. 2485), would further serve to increase energy efficiency and reduce consumption of fossil fuels. The energy demands during construction would be typical of construction projects for projects of this size and would not necessitate additional long-term Lyons Avenue/Dockweiler Drive Extension Project Addendum 4. Environmental Impact Analysis SCH No. 2013082016 Page 4-19 City of Santa Clarita May 2021 energy facilities or distribution infrastructure or cause wasteful, inefficient or unnecessary consumption of energy. Accordingly, energy demands during construction would be less than significant. Operation The Modified Project consists of a roadway extension project aimed to improve circulation and access in the Placerita Canyon and Newhall communities and does not include any buildings or land uses. Therefore, the Modified Project would not generate electricity or natural gas demands during operation. Transportation Energy The Modified Project consists of a roadway extension to Dockweiler Drive, aimed to improve circulation and access in the Placenta Canyon and Newhall communities. As discussed in the Transportation section below, the Modified Project would alter traffic distribution, which would also reduce delays in the area when compared to existing conditions (2019). Thus, the Modified Project would promote reductions in vehicle -miles -traveled (VMT) and would lessen the amount of time spent along these roadways. Additionally, Class II bike lanes, multiuse paths and pedestrian sidewalks would be provided to enhance non -auto travel safety and promote connectivity between The Master's University, the Newhall Metrolink Station and Old Town Newhall. The Modified Project would include a bicycle and pedestrian pathway south of Dockweiler Drive, that spans Newhall Creek, to connect with the northwest end of the Newhall Metrolink Station parking lot, located to the south of the proposed Dockweiler Drive extension. This would aim to reduce trips and promote the use of other modes of transportation. Therefore, the operation of the Modified Project would result in improved circulation in the local area, reduce VMT, decrease delays, promote alternate modes of transportation, and reduce its reliance on transportation energy. Thus, impacts from transportation energy would be less than significant. b) Would the Project conflict with or obstruct a state or local plan for renewable energy or energy efficiency? The Modified Project consists of a roadway extension project aimed to improve circulation and access in the Placerita Canyon and Newhall communities and does not include any buildings or land uses. Therefore, the Modified Project would not generate electricity or natural gas demands during operation. With respect to transportation energy, vehicle trips generated during the Modified Project operations would comply with CAFE fuel economy standards. During construction activities, the Modified Project would be required to comply with CARB anti -idling regulations and the In -Use Off -Road Diesel Fleet regulations. As such, the Modified Project would not conflict with or obstruct a state or local plan for renewable energy or energy efficiency, and impacts would be less than significant. Lyons Avenue/Dockweiler Drive Extension Project Addendum 4. Environmental Impact Analysis SCH No. 2013082016 Page 4-20 City of Santa Clarita May 2021 4.6 GEOLOGY AND SOILS Approved Project As concluded in the EIR, the potential for earthquake -induced slope failure at the Project Site is considered low provided that future geologic and geotechnical evaluations and recommendations for slope stability are incorporated into design and construction of the Approved Project. Additionally, specific recommendations for design and construction would address soil stability, including: hydro -compression, expansive soils, rippability, the handling of oversized material, soil corrosivity, shirking and bulking of materials, and the handling of the need for retaining wall. As concluded in the Final EIR, the implementation of Mitigation Measure 4.5-1 and 4.5-2 would ensure that potential project impacts associated with geotechnical stability and earthwork would be reduced to a less than significant level. Paleontological Resources As discussed in the EIR, the records search conducted by the Vertebrate Paleontology Department of the Natural History Museum of Los Angeles County yielded no known fossil localities within the Project Site. While it is possible that fossilized materials may be discovered during site preparation and construction, specifically grading and excavation activities, precautionary measures set forth in Mitigation Measure 4.4- 2 would reduce any potential adverse impacts related to the discovery of paleontological resources during construction -related earthwork activities to a less than significant level. Modified Project Like the Approved Project, the potential for earthquake -induced slope failure at the Project Site is considered low provided that future geologic and geotechnical evaluations and recommendations for slope stability are incorporated into design and construction of the Modified Project. Additionally, specific recommendations for design and construction would address soil stability, including: hydro -compression, expansive soils, rippability, the handling of oversized material, soil corrosivity, shirking and bulking of materials, and the handling of the need for retaining wall. Similar to the Approved Project, implementation of Mitigation Measure 4.5-1 and 4.5-2 would ensure that potential project impacts associated with geotechnical stability and earthwork would be reduced to a less than significant level. The Modified Project would not result in impacts that are more severe than those that were identified under the Approved Project in the EIR. Paleontological Resources The southeastern grading limits for the Modified Project (between Arch Street and The Master's University project limits) are generally within the grading limits that were analyzed for both the Original Project and the Approved Project. The Modified Project would include a larger grading footprint on the northern portion of the Project Site (approximately seven acres), as compared to the Original Project and Approved Project, to accommodate the roadway improvements at Arch Street, 13th Street and Placerita Canyon Road, the intersection improvements at 13th Street and Railroad Avenue, grading improvements along the Lyons Avenue/Dockweiler Drive Extension Project Addendum 4. Environmental Impact Analysis SCH No. 2013082016 Page 4-21 City of Santa Clarita May 2021 UP/Metrolink railroad line between 13th Street and 15th Street, and the addition of two new stormwater treatment basins. Like the Approved Project, site preparation and construction, specifically grading and excavation activities may unearth fossilized materials. Precautionary measures as identified in Mitigation Measure 4.4-2 would reduce any potential adverse impacts related to the discovery of paleontological resources during construction -related earthwork activities to a less than significant level. Therefore, impacts related to paleontological resources would be the same as compared to the Approved Project. 4.7 HYDROLOGY AND WATER QUALITY Approved Project Construction The Approved Project would be required to prepare and implement a Storm Water Pollution Prevention Plan (SWPPP) prior to earthwork activities that will put best management practices and erosion control measures to prevent pollution in stormwater discharge. Through compliance with National Pollutant Discharge Elimination System (NPDES) requirements and City grading regulations, the Approved Project's construction impacts related to water quality would not violate any water quality standards or waste discharge requirements or otherwise substantially degrade water quality. Construction -related impacts to hydrology and water quality would therefore be less than significant. Operation In accordance with NPDES requirements, the Project Applicant would be required to have a Project -specific Standard Urban Storm Water Mitigation Plan (SUSMP) in place during the operational life of the Project to address the management of runoff from the proposed roadway extension. The SUSMP would include site design, source control, low -impact development, and best management practices. Therefore, implementation of the storm water quality plan would reduce water quality impacts during the Approved Project's operation to less than significant. Inundation and Flooding As concluded in the Final EIR, unlike the Original Project, the Approved Project, does not include the roadway extension from Lyons Avenue to Dockweiler Drive, which spans a portion of the Newhall Creek. As such, the Approved Project would not include the development of a new bridge across Newhall Creek or require embankment protection to the roadway and creek and would not result in impacts upon hydrologic flows within Newhall Creek. Lyons Avenue/Dockweiler Drive Extension Project Addendum 4. Environmental Impact Analysis SCH No. 2013082016 Page 4-22 City of Santa Clarita May 2021 Modified Project Construction Like the Approved Project, the Modified Project would be required to prepare and implement a Storm Water Pollution Prevention Plan (SWPPP) prior to earthwork activities that will implement best management practices and erosion control measures to prevent pollution in stormwater discharge. Through compliance with National Pollutant Discharge Elimination System (NPDES) requirements and City grading regulations, the Modified Project's construction impacts related to water quality would not violate any water quality standards or waste discharge requirements or otherwise substantially degrade water quality. The Modified Project's construction -related impacts to hydrology and water quality would therefore be less than significant. Operation As shown in Figure 2-6 Modified Project Site Plan the Modified Project would include the addition of two basins for stormwater capture and treatment associated with the roadway improvements; one interim detention basin would be located to the north of 13th Street and east of Railroad Avenue (see Figure 2-7 Modified Project Grading Plan at Railroad Avenue and 13th Street) and one infiltration basin would be located south of the improvements as Placenta Canyon Road and east of the proposed Dockweiler Drive Alignment (see Figure 2-8 Modified Project Grading Plan at Arch Street/ 12th Street/ Placenta Canyon Road/ Dockweiler Drive Extension Intersection). Like the Approved Project, the Modified Project would be required to have a Project -specific SUSMP in place during the operational life of the Project to address the management of runoff from the proposed roadway extension in accordance with NPDES requirements. The SUSMP would include site design, source control, low -impact development, and treatment control BMPs and would address site design BMPs (such as minimizing impervious areas, maximizing permeability, minimizing directly connected impervious areas, and creating reduced or "zero discharge" areas); incorporate applicable source control BMPs; incorporate treatment control BMPs as described in the Los Angeles County SUSMP; describe long-term operation and maintenance requirements for the treatment control BMPs; and describe the mechanism for funding the long-term operation and maintenance of the treatment control BMPs. The final selection of BMPs would be completed through coordination with the City. Also, per the NPDES, the storm water quality plan would be subject to review and approval by the City for compliance with the County's Development Best Management Practices Handbook, Low Impact Development Manual, Part B Planning Activities. As stated in the Low Impact Development Manual, because the Modified Project would result in the construction of a roadway of more than 10,000 square feet, the Modified Project would be required to comply with the US Environmental Protection Agency's (USEPA) guidance on "green streets",' to the maximum extent feasible. The EPA's green streets manual provides guidance on a variety of design 8 US Environmental Protection Agency, Managing Wet Weather with Green Infrastructure: Green Streets 26, EPA-833-F-08-009, December 2008.

Environmental Impact Analysis SCH No. 2013082016 Page 4-23 City of Santa Clarita May 2021 elements including street trees, permeable pavements, bioretention, and swales, in an effort to provide source control of stormwater, limit its transport and pollutant conveyance to the collection system, restore predevelopment hydrology to the extent possible, and provide environmentally enhanced roads.' Therefore, like the Approved Project, with implementation of the storm water quality plan as discussed above, water quality impacts during operation of the Modified Project would be less than significant. Inundation and Flooding Portions of the roadway improvements along Arch Street and 13th Street, and the bicycle and pedestrian pathway and bridge south of Dockweiler Drive, are located in a "Zone A", as indicated in the National Flood Insurance Rate Map for Los Angeles County, which indicates a special flood hazard area that is subject to inundation by the 1% annual chance flood (100-year flood).10 Like the Approved Project, the Modified Project does not include the roadway extension from Lyons Avenue to Dockweiler Drive, which spans a portion of the Newhall Creek. However, the proposed bicycle and pedestrian pathway south of Dockweiler Drive, would span a portion of the Newhall Creek, to connect with the northwest end of the Newhall Metrolink Station parking lot, located to the south of the proposed Dockweiler Drive extension. With respect to the Original Project, the EIR concluded that the proposed bridge and channel improvements, associated with the roadway extension, could accommodate the Capital Flood and would not create any flood hazard for the adjacent railroad and proposed street improvements with implementation of regulatory code compliance. Installation of the bicycle and pedestrian bridge would be implemented by placing the footings upland and outside of Newhall Creek. Unlike the Original Project, which included the installation of footings within the creek channel, this alternative would avoid direct impacts within the creek bed. As the bicycle and pedestrian bridge proposed under the Modified Project is generally within the same outer footprint as the roadway alignment analyzed for the Original Project, and would generally be smaller in scale and scope, as compared to the roadway alignment, impacts associated with inundation and flooding would be less than significant and would not result in new or more severe impacts as those analyzed in the Final EIR under the Approved Project.

Lyons Avenue/Dockweiler Drive Extension Project Addendum 4. Environmental Impact Analysis SCH No. 2013082016 Page 4-24 City of Santa Clarita May 2021 4.8 LAND USE AND PLANNING Approved Project The Approved Project would involve the development of the proposed roadway alignment and associated infrastructure for Dockweiler Drive, which would extend Dockweiler Drive to Arch Street. Unlike the Original Project, the Approved Project does not include the roadway segment between the Dockweiler extension and Lyons Avenue. The route would continue along Arch Street to 13th Street to link to Railroad Avenue. Additionally, Approved Project proposes to maintain and improve the 13th Street rail crossing. As discussed in the Final EIR, the Approved Project is in substantial compliance with the applicable land use plans, policies, or regulations, including: the Regional Transportation Plan / Sustainable Communities Strategy (RTP/SCS), City of Santa Clanta Municipal Code, City of Santa Clanta General Plan (including the Circulation Element), the Placenta Canyon Special Standards District and North Newhall Area, Old Town Newhall Specific Plan, and the Compass Blueprint Concept Plan. As such, implementation of the Approved Project would create a less than significant impact with regards to land use and planning. Modified Project Like the Original Project and Approved Project, the Modified Project would be consistent with the City's Circulation Element as an additional route of travel connecting Railroad Avenue to Dockweiler Drive. The Modified Project would include upgrades to the at -grade railroad crossing at the intersection of Railroad Avenue and 13th street, new turn lanes, roadway widening, and median improvements. The Modified Project would also introduce a roundabout at the 12th Street/ Arch Street/ Dockweiler Drive intersection and modify the roadway connection from Dockweiler Drive to Placenta Canyon Road. These roadway improvements would improve traffic operations and enhance the safety of pedestrians and bicyclists. Additionally, the extension of Dockweiler Drive would promote non -auto travel by including a bicycle and pedestrian pathway south of Dockweiler Drive, that spans Newhall Creek, to connect with the northwest end of the Newhall Metrolink Station parking lot, located to the south of the proposed Dockweiler Drive extension. These improvements would provide connectivity from, Old Town Newhall and the Metrolink Station to The Master's University. As such, the Modified Project would similarly not conflict with any applicable land use plans, policies, or regulations identified under the Approved Project. Implementation of the Modified Project would create a less than significant impact with regards to land use and planning and would be similar to those impacts analyzed for the Approved Project. 4.9 NOISE Approved Project Construction The Approved Project would require the use of heavy equipment for ground clearing, site grading, and roadway construction. Several pieces of construction equipment operating simultaneously would generate a noise level of approximately 94.6 dBA. The estimated construction noise levels impacting sensitive Lyons Avenue/Dockweiler Drive Extension Project Addendum 4. Environmental Impact Analysis SCH No. 2013082016 Page 4-25 City of Santa Clarita May 2021 receptors are expected to exceed the City's daytime noise standards for residential uses (see Section 4.8, Noise, Table 4.8-9, Estimated Exterior Construction Noise at Nearest Sensitive Receptors, of the EIR). Notwithstanding implementation of Mitigation Measures 4.8-1 through 4.8-9, which would require best practices to reduce construction related noise, construction noise levels would still constitute a significant unavoidable impact. Operational Section 4.8 Noise, of the EIR, analyzed operational noise impacts resulting from the proposed Original Project, which included the extension of the proposed Dockweiler Drive roadway to Lyons Avenue, a new at grade railroad crossing at Lyons Avenue and Railroad Avenue, and the closure of the 13th Street and Railroad Avenue intersection. The changes in future noise levels along the study -area roadway segments in the project vicinity for the Original Project near term (Year 2019) impacts would increase local noise levels by a maximum of 2.7 dBA CNEL (at the location of Dockweiler Drive (between Sierra Highway and Valle del Oro) (see Section 4.8, Noise, Table 4.8-11 Future (2019) Project Roadway Noise Impacts at Off -Site Locations, of the EIR). This increase would be below the identified thresholds of significance. At all other roadway segments, the resulting noise levels are anticipated to decrease. Similarly, the EIR concluded that the Approved Project's potential to generate a substantial permanent increase in ambient noise levels in the project vicinity above existing levels would also be less than significant as the Approved Project would exclude the extension of Dockweiler Drive to Lyons Avenue but would include improvements to the intersection of Arch Street, 12th Street and Placenta Canyon Road, and at -grade railroad crossing and roadway improvements at the intersection of 13th Street and Railroad Avenue. Under the proposed Original Project scenario, the Future (2019) With Project noise levels on the new roadway segment from Lyons Avenue to Valle del Oro are expected to be 63.3 dBA (CNEL) within 50 feet of the centerline of the roadway. The resulting noise levels at the three identified sensitive receptors would be below 52.9 dBA (see Section 4.8, Noise, Table 4.8-12 Estimated Roadway Noise at Nearest Sensitive Receptors, of the EIR). Thus, the anticipated with project noise levels at all off -site receptor locations would be within the "normally acceptable" range of noise for residential areas. The Approved Project would direct more traffic through Arch Street and 13th Street. The land uses along Arch Street and 13th Street are commercial properties and are not considered sensitive land uses for purposes of evaluating noise impacts. Thus, noise impacts associated with the change of traffic flows under the Approved Project would be less than significant. Lyons Avenue/Dockweiler Drive Extension Project Addendum 4. Environmental Impact Analysis SCH No. 2013082016 Page 4-26 City of Santa Clarita May 2021 Modified Project Construction Like the Original and Approved Project, the Modified Project would require the use of heavy equipment for ground clearing, site grading, and roadway construction. Subsequent to the preparation of the EIR, a new mixed -use apartment complex located at 24480 Main Street (Newhall Crossings) has been completed (see Sensitive Receptor No. 6, Figure 4-2). This property is located more than 500 feet from a majority of where the Modified Project's construction would occur and would only be subject to potential construction noise impacts during the construction of the bicycle and pedestrian path and bridge that would connect Dockweiler Drive and the Metrolink Station parking lot. As discussed above, the Original Project's construction noise analysis analyzed the extension of Lyons Avenue, which would span Newhall Creek, to connect to the proposed Dockweiler Drive. The Modified Project would not include the roadway extension of Lyons Avenue and instead would include a pedestrian and bicycle bridge that would cross Newhall Creek to connect with the northwest end of the Newhall Metrolink Station parking lot (see Figure 2-10 Modified Project Bike Path). Construction of the pedestrian and bicycle bridge would require cast -in -drilled -hole concrete piling to install three piles per bridge abutment (six piles total). Drilling activity associated with the piles would occur over approximately ten days during Phase I of construction." The use of drilling equipment for the piles would be limited to the permissible hours of construction and building activity pursuant to the City's Municipal Code12. Table 4-4 shows the estimated noise levels from the identified sensitive receptors and the location of drilling activity. As shown in Table 4-4, construction noise related to drilling activity would exceed the threshold level for the residential uses at Sensitive Receptor No. 6 (Newhall Crossings). Pursuant to the City of Santa Clarita Municipal Code, Section 11.44.040 (B), Noise Limits, Noise Condition (1), a -5 dBA correction to the noise limits for the sensitive receptors would be applied to adjust for the repetitive impulsive noise resulting from use of drilling equipment. 13 Therefore, construction noise generated by the drilling activities would impact one of the eight " As discussed above under Subsection 2.6, Modified Project, Phase I includes the construction of the widening of 13' Street and Arch Street, and Dockweiler Drive, east of Placerita Canyon Road, to the Master's University's portion of Dockweiler Drive to the southeast. 12 Section 11.44.080 of the Noise Ordinance provides noise standards for construction and building activities. Pursuant to Section 11.44.080, no person shall engage in any construction work which requires a buildingpermit from the City on sites within three hundred (300) feet of a residentially zoned property except between the hours of 7: 00 A.M. to 7: 00 P.M., Monday through Friday, and 8: 00 A.M. to 6: 00 P.M. on Saturday. Further, no work shall be performed on the following public holidays: New Year's Day, Independence Day, Thanksgiving, Christmas, Memorial Day and Labor Day. Emergency work as defined in Section 11.44.020(D) is permitted at all times. 13 See Table 4.8-3, City Ordinance Noise Limits, Part B, Corrections to Noise Limits, (1) Repetitive Impulsive Noise, of the EIR, for additional factors and circumstances. Pursuant to the City of Santa Clarita Municipal Code, Section 11.44.040 (B), Noise Limits. Lyons Avenue/Dockweiler Drive Extension Project Addendum 4. Environmental Impact Analysis SCH No. 2013082016 Page 4-27 City of Santa Clarita May 2021 sensitive receptors within the Project Site vicinity but would not result in more severe impacts as compared to impacts identified in the EIR under the Original Project. Notwithstanding implementation of Mitigation Measures 4.8-1 through 4.8-9, and the addition of Mitigation Measure 4.8-10 (see below), which would require best practices to reduce drilling noise, the noise levels associated with drilling activity would still constitute a significant and unavoidable impact, similar to the Original and Approved Project. With respect to any vibration impacts from drilling activity, because of the distances from the nearest sensitive receptors to the location of drilling, the drilling activities would not result in any structural vibration impacts to any sensitive receptors. Although drilling activity would only occur for a duration of approximately ten days during Phase I of construction, and notwithstanding Mitigation Measure 4.8-9 (Temporary Noise Barrier), the addition of Mitigation Measure 4.8-10, below, would ensure that noise impacts to sensitive receptors resulting from drilling activity would be reduced to the maximum extent feasible: 4.8-10 The project contractor shall erect a temporary noise -attenuating sound barrier along the perimeter(s) where drilling activity associated with the installation of piles occurs on the Project Site. The sound barrier will be a minimum of 8 feet in height to block the line -of -sight of construction equipment and off -site receptors. Additionally, the Modified Project would include roadway improvements along Placenta Canyon Road to connect the existing street with the proposed roundabout at the Arch Street/12th Street and Placerita Canyon Road intersection. Several single-family homes near the intersection of Placenta Canyon Road and Aden Avenue are located within 500 feet of the Modified Project's grading limits (see Sensitive Receptor No. 7, Figure 4-2). The Modified Project's grading limits would also extend further north along Railroad Avenue as compared to the Approved Project. Therefore, the residential mobile homes fronting Railroad Avenue and the residences further west of Railroad Avenue, fronting Walnut Street, would be located within 500 feet of the Project Site (see Sensitive Receptor No. 8, Figure 4-2). The estimated construction noise levels impacting these sensitive receptors (Sensitive Receptor No. 6, 7 and 8) are shown in Table 4-4, below. As shown in Table 4-4, construction noise would exceed the threshold level for the residential uses at Sensitive Receptor No. 6, 7 and 8. Therefore, construction noise generated by the Modified Project would affect three additional sensitive receptors in the Project Site vicinity but would not result in more severe impacts as compared to impacts identified in the EIR under the Original and Approved Project. Notwithstanding implementation of Mitigation Measures 4.8-1 through 4.8-9, which would require best practices to reduce construction related noise, construction noise levels would still constitute a significant and unavoidable impact, similar to the Approved Project.

PARKER Figure 4-2 ENVIRONMENTAL CONSULTANTS Noise Monitoring Location Map City of Santa Clarita May 2021 Operational Similar to the Approved Project, the Modified Project would alter roadway traffic volumes as the Modified Project would create a new roadway segment connecting 13th Street and Arch Street to the proposed Dockweiler Drive roadway extension. As such, the Modified Project would not directly generate any new vehicle trips; however, locations in the vicinity of the Project Site could experience slight changes in noise levels as a result of the change in traffic patterns. As discussed above under the Approved Project, the changes in future noise levels along the study -area roadway segments in the project vicinity area for the Original Project near term (Year 2019) impacts would be below the identified thresholds of significance. In addition, the resulting noise levels from the additional vehicle trips generated by the Original Project at the identified sensitive receptors would be within the "normally acceptable" range of noise for residential areas. The Modified Project includes the extension of Dockweiler Drive to Arch Street, as well as the installation of a roundabout at the intersection of the Arch Street/12th Street/Placenta Canyon intersection, a pedestrian and bicycle pathway that would span Newhall Creek, reprofiling of the UP/Metrolink railroad track, and the addition of stormwater treatment basins. Since the preparation of the EIR, a new apartment complex located at 24480 Main Street (Newhall Crossings), has been completed (see Sensitive Receptor No. 6, Figure 4-2). This property is located more than 600 feet southwest from the roadway extension portion of Dockweiler Drive and as such, would not incur additional operational noise impacts associated with vehicle traffic along the roadway extension. Additionally, the Modified Project would include grading improvements along Placenta Canyon Road to match the profile of the street to the proposed roundabout. Several single-family homes near the intersection of Placerita Canyon Road and Aden Avenue are located within 500 feet of the Modified Project's grading limits (see Sensitive Receptor No. 7, Figure 4-2) but are located over 700 feet from the proposed roundabout configuration. As such, these residences would not experience a significant increase related to roadway traffic along Placenta Canyon Road or the proposed roundabout. The Modified Project's grading limits would also extend further north along Railroad Avenue to accommodate the reprofiling of the UP/Metrolink railroad track (within the railroad's right-of-way, largely between 13th Street and 15th Street). Although the residential mobile homes fronting Railroad Avenue (located one block south of 15th Street and Railroad Avenue) (see sensitive Receptor No. 8, Figure 4-2) and the residences further west of Railroad Avenue, fronting Walnut Street, would be located within 500 feet of the Project Site, no new traffic configurations are proposed along this section of the Project Site, as modifications are limited to grading. The infrastructure improvements related to stormwater capture and railroad track reprofiling would not generate new roadway noise. With respect to roadway noise generated under the Modified Project at the intersection of 13th Street and Railroad Avenue, and 13th Street and Arch Street, land uses along Arch Street and 13th Street are commercial properties and are not considered sensitive land uses for purposes of evaluating noise impacts. Lastly, the footprint of the extension of Dockweiler Drive from Arch Street on the northwest to The Master's University project site limits to the southeast is largely within the same footprint of the Original Project that was analyzed in the EIR. As such, operational noise impacts on the residential uses along Aden Avenue would be similar to those analyzed under the Approved Project. Lyons Avenue/Dockweiler Drive Extension Project Addendum 4. Environmental Impact Analysis SCH No. 2013082016 Page 4-32 City of Santa Clarita May 2021 Therefore, like the Approved Project, the Modified Project's potential to generate a substantial permanent increase in ambient noise levels in the project vicinity above existing levels would be less than significant. In summary, operational noise impacts associated with the change of traffic flows under the Modified Project would be less than significant and would not result in new or more severe impacts as compared to impacts analyzed in the EIR under the Approved Project. 4.10 TRANSPORTATION Approved Project The summary of the Approved Project's traffic impacts discussed below is based on Section 6.4 Alternative 2, of the EIR, and the Traffic Study titled, Traffic Impact Analysis: Dockweiler Drive Extension Project, Santa Clarita, CA, prepared by David Evans and Associates, dated August 8, 2017. The complete Traffic Study is included in Appendix H of the EIR. Opening Year (2019) Conditions The Santa Clarita Valley Consolidated Traffic Model (SCVCTM) for Interim Year provided traffic volumes for the Project Year 2019. The Project Year 2019 Approved Project study intersections and the volumes are provided in Section 6.4 Alternative 2, Figure 6.4-7 and Figure 6.4-8, respectively, of the EIR. The analysis for the intersection of Arch Street/Dockweiler Drive and 12th Street/Placenta Canyon Road was conducted as a 5-leg all way stop controlled intersection. The intersections were analyzed using the capacity analysis methodology. The analysis was conducted with the Project Year 2019 with the Approved Project existing and mitigated study intersection geometries illustrated in in Section 6.4 Alternative 2, Figure 6.4-9, of the EIR. The LOS for the study intersections presented in Section 6.4 Alternative 2, Table 6.4-1 of the EIR, represents the LOS for the critical movement. As concluded in the Final EIR, most of the study intersections are anticipated to continue to operate at LOS E or better under the Approved Project. Four intersections are anticipated to operate at LOS F, they are: Sierra Highway and SR-14 Southbound Ramps, Sierra Highway and Placenta Canyon Road, SR-14 Northbound Ramps and Placenta Canyon Road, SR-14 Southbound Ramps and Newhall Avenue. Conclusion With mitigation, the Sierra Highway and SR-14 Southbound Ramp intersection (see Study Intersection 1, Section 6.4 Alternative 2, Figure 6.4-7) levels of service will increase to LOS B and LOS C during the AM and PM peak hours, respectively. With mitigation, the Sierra Highway and Placenta Canyon Road intersection (see Study Intersection 2, Section 6.4 Alternative 2, Figure 6.4-7) level of service will remain the same at LOS C during the AM peak hour and will increase to LOS D during the PM peak hour. With mitigation, the SR-14 Northbound Ramps and Placenta Canyon Road intersection (see Study Intersection 3, Section 6.4 Alternative 2, Figure 6.4-7) level of service will remain the same at LOS B during the AM peak hour and will increase to LOS B during the PM peak hour. With mitigation, the SR-14 Southbound Lyons Avenue/Dockweiler Drive Extension Project Addendum 4. Environmental Impact Analysis SCH No. 2013082016 Page 4-33 City of Santa Clarita May 2021 Ramps and Newhall Avenue intersection (see Study Intersection 5, Section 6.4 Alternative 2, Figure 6.4-7) levels of service will increase to LOS A during both AM and PM peak hours. In summary, with the implementation of Mitigation Measures 4.9-1, 4.9-3, and 4.9-6 through 4.9-16 the Approved Project's impacts during the 2019 build -out year would be less than significant. Future (2035) Conditions The Santa Clarita Valley Consolidated Traffic Model (SCVCTM) for Build -Out Year provided traffic volumes for the Future Year 2035. The analysis of the Approved Project utilizes the traffic volume projections for the City of Santa Clanta's traffic model together with the existing traffic flow data. The traffic projections are based on the General Plan Buildout. The buildout includes construction of future roadways Dockweiler Drive between 13th Street and Valle Del Oro, Magic Mountain Parkway from Railroad Avenue to Via Princessa, between Claibourne Lane and Sheldon Avenue, and Santa Clanta Parkway. This also includes the proposed conceptual development of the North Newhall area (809 dwelling unit plus an approximate 11-acre commercial land use). The Future Year 2035 Approved Project study intersections and the volumes are provided in Section 6.4 Alternative 2, Figure 6.4-10 and Figure 6.4-11, respectively, of the EIR. The intersections were analyzed using the capacity analysis methodology. The analysis was conducted with the Future Year 2035 Approved Project existing and mitigated study intersection geometncs illustrated in Section 6.4 Alterative 2, Figure 6.4-12 of the EIR. The LOS for the study intersections presented in Section 6.4 Alterative 2, Table 6.4-2, of the EIR, represents the LOS for the critical movement. As presented in Section 6.4 Alterative 2, Table 6.4-2 under Future Year 2035 with the Approved Project, several of the study intersections are anticipated to operate at LOS F. There are five intersections that are anticipated to operate at LOS F, they are: Sierra Highway and Placenta Canyon Road, Sierra Highway and Newhall Avenue, Valle Del Oro and Dockweiler Drive, Railroad Avenue and 13th Street, and Main Street and Newhall Avenue. Conclusion With mitigation, the Sierra Highway and Placenta Canyon Road intersection (see Study Intersection 2, Section 6.4 Alternative 2, Figure 6.4-10) levels of service will increase from a LOS F to LOS D during both AM and PM peak hours. With mitigation, the Sierra Highway and Newhall Avenue intersection (see Study Intersection 6, Section 6.4 Alternative 2, Figure 6.4-10) levels of service will increase from LOS E to LOS D during the AM peak hour and LOS F to LOS D during the PM peak hour. With mitigation, the Valle Del Oro and Dockweiler Drive intersection (see Study Intersection 8, Section 6.4 Alternative 2, Figure 6.4-10) levels of service will increase from a LOS F to LOS C during the AM peak hour and remain at a LOS C during the PM peak hour. With mitigation, the Railroad Avenue and 13th Street intersection (see Study Intersection 13, Section 6.4 Alternative 2, Figure 6.4-10) levels of service will remain at a LOS D during the AM peak hour and increase from a LOS F to LOS D during the PM peak hour. With mitigation, the Main Street and Newhall Avenue intersection (see Study Intersection 15, Section 6.4 Alternative 2, Figure Lyons Avenue/Dockweiler Drive Extension Project Addendum 4. Environmental Impact Analysis SCH No. 2013082016 Page 4-34 City of Santa Clarita May 2021 6.4-10) levels of service will increase from LOS F to LOS A during the AM peak hour and LOS F to LOS B during the PM peak hour. In summary, with the implementation of Mitigation Measures 4.9-1, 4.9-3, and 4.9-6 through 4.9-16 the Approved Project's impacts during the 2035 year would be less than significant. Railroad Crossing Analysis The Approved Project scenario for Daily, AM and PM Peak hour traffic volumes were compiled for the Year 2019 and 2035 conditions as presented in Section 6.4 Alternative 2, Table 6.4-3 and Table 6.4-4, respectively. As presented in Table 6.4-3, the total average daily traffic is anticipated to be higher under the No Build Condition as compared to the Original Project and the Approved Project. The Approved Project's total average daily railroad crossings would result in 6,390 fewer crossings as compared to the No Build condition and 820 fewer railroad crossings as compared to the Original Project. For the Year 2035 Condition, the total average daily traffic is anticipated to be highest under the Original Project. The Approved Project would result in 3,370 fewer crossings as compared to the No Build condition and 6,230 fewer crossings than the Original Project. Bicycle and Pedestrian Facilities The Approved Project would comply with Santa Clarita's circulation goals and enhancing the circulation system by providing bicycle lanes and accessibility to bicycle paths that are fundamental for a comprehensive transportation network. Vehicle Miles Traveled As discussed in Section 4.9 Transportation and Traffic, of the EIR, The Original Project is identified as one of the financially constrained projects within the RTP/SCS, as shown in Table 1, 2020-2045 RTP/SCS Project LiSt. 14 As such, the Approved Project is recognized as part of the regional strategy that is consistent with SCAG's policies to reduce vehicle miles traveled (VMTs). The Approved Project is also consistent with the City's Circulation Element as an additional route of travel connecting Railroad Avenue to Dockweiler Drive. Because no new land uses are being proposed, the Approved Project would not generate any new vehicle trips and thus would not have the potential to increase VMTs on a per capita basis. Modified Project The summary of the Modified Project's traffic impacts, discussed below, is based on the Dockweiler Drive Extension Project Traffic Study, prepared by ADVANTEC Consulting Engineers, dated September 2020. The complete Traffic Study is included in Appendix D of this Addendum. 14 Southern California Association of Governments, Connect SoCal (2020-2045 Regional Transportation Plan/Sustainable Communities Strategy), Technical Report, Project List, Table 1, FTIP Projects, page 27. Lyons Avenue/Dockweiler Drive Extension Project Addendum 4. Environmental Impact Analysis SCH No. 2013082016 Page 4-35 City of Santa Clarita May 2021 The Traffic Study analyzed three alternatives at the intersection of Arch Street, 12th Street, Placenta Canyon and Dockweiler Drive. Alternative 2 of the Traffic Study is consistent with the Modified Project as identified in this Addendum. In summary, the Modified Project proposes to extend Dockweiler Drive from its existing terminus, westward to intersect with Arch Street, and 12th Street providing a 4-legged roundabout with a signalized offset T-intersection with Placenta Canyon Road. The roundabout will have one main lane in the circle, with one lane approach from Arch Street, Dockweiler Drive, and 12th Street. Methodology The Traffic Study notes that based upon the proposed intersection alternatives and discussion with the City of Santa Clarita, it was determined that comparing Level of Service (LOS) would not be appropriate, as roundabouts and standard intersections operate differently. Therefore, Vehicle Queue Lengths and Vehicle Delay at the approaches of the Dockweiler Drive/12th Street/Placerita Canyon Road study intersection would be estimated to determine how each alternative performs. Synchro/Simtraffic simulation was used to estimate vehicle queue lengths and vehicle delay. A 30-minute simulation was run using the peak hour volumes (AM and PM) for 2025 and 2035. A 2019 No -Build simulation was also created using existing traffic volumes. The simulations were then used to record the maximum queue (feet) and total delay (seconds per vehicle) experienced. The maximum queue was reported per lane group (i.e., exclusive lefts, through/shared, or exclusive rights). The total delay was reported per intersection approach. Traffic volumes for year 2025 and 2035 were obtained from the Traffic Impact Study15 of the Final EIR. The EIR's Year 2035 scenarios (Alternative 2 and No Build) traffic volumes were then adjusted to remove the traffic volumes corresponding to the Traffic Analysis Zone that represents the currently undeveloped area north of 13th Street/Arch Street. The removed traffic volumes were then replaced with the projected volumes for the Placerita Meadows development16, with access points at 13th Street and at 12th Street. The Placerita Meadows development was assumed to be fully built by Year 2025. A project year of 2025 was identified as the opening year for the Modified Project. Traffic volumes for year 2025 were calculated by interpolation between the EIR Alternative 2 Year 2019 and Year 2035 traffic volumes. Opening Year (2025) Conditions Table 4-5 and Table 4-6 below summarize the Opening Year 2025 maximum queue length and delay per vehicle for the study intersections, respectively. Figure 4-3 and Figure 4-4 provide the Modified Project's is Traffic Impact Analysis: Dockweiler Drive Alignment Project, Santa Clarita, CA, prepared by David Evans and Associates, dated August 8, 2017.

Horizon Year (2035) Conditions Table 4-7 and Table 4-8 below summarize the Horizon Year 2035 maximum queue length and delay per vehicle for the study intersections, respectively. Figure 4-5 and Figure 4-6 provide the Modified Project's traffic volumes for Horizon Year 2035 for Railroad Avenue/13th Street and the Dockweiler Drive/12tn Street/Placerita Canyon Road study intersections, respectively. Conclusion As concluded in the Traffic Study, the results of the Vehicle Queue Length analysis for 13th Street/Railroad Avenue intersection show that the Modified Project produced maximum queue lengths between 74 feet and 276 feet during AM period and between 22 feet and 362 feet during PM period for the Opening Year 2025 scenario. Additionally, the Modified Project produced maximum queue lengths between 96 feet and 298 feet during AM period and between 96 feet and 397 feet during PM period for the Horizon Year 2035 scenario. The results of the Vehicle Queue Length analysis for Dockweiler Drive/ 12th Street intersection show that the Modified Project produced maximum queue lengths between 32 feet and 174 feet during AM period and between 32 feet and 202 feet during PM period for the Opening Year 2025 scenario. Additionally, the Modified Project produced maximum queue lengths between 53 feet and 153 feet during AM period and between 53 feet and 228 feet during PM period for the Horizon Year 2035 scenario. The results of the Vehicle Queue Length analysis for Dockweiler Drive/Placerita Canyon Road intersection show that the Modified Project produced maximum queue lengths between 97 feet and 124 feet during AM period and between 72 feet and 92 feet during PM period for the Opening Year 2025 scenario. Additionally, the Modified Project produced maximum queue lengths between 74 feet and 117 feet during AM period and between 96 feet and 190 feet during PM period for the Horizon Year 2035 scenario. These results indicate that the average queues expected to be experienced by drivers should not cause blockage of turn pockets or through lanes. As noted above, traffic volumes for the Traffic Study were based on results of the Traffic Impact Study for the EIR and its assumptions for traffic forecast modeling. According to the Model Plots supplied in Appendix A of the Traffic Study, the No Build 2035 model assumes that there will be an additional roadway link extending from the existing Dockweiler Drive terminus to Master's University. This assumption in the No Build 2035 model alters the traffic distribution in the area and reduces the volumes at the intersection of 13th Street/Railroad Avenue intersection. The Model Plot for No Build 2019 does not assume this additional link. For this reason, traffic volumes at 13th Street/Railroad show a decrease from 2019 to 2035, which in turn causes a decrease in delay in future year (2035) when compared to existing (2019) and opening year (2025). Lyons Avenue/Dockweiler Drive Extension Project Addendum 4. Environmental Impact Analysis SCH No. 2013082016 Page 4-37 City of Santa Clarita May 2021 which in turn causes a decrease in delay in future year (2035) when compared to existing (2019) and opening year (2025). Traffic volumes for 2035 horizon year were updated with more recent information on the Placerita Meadows development and the Traffic Analysis Zone it lies in. This caused volumes to decrease substantially on the segment between Railroad Ave and 13th Street and 12th Street and Dockweiler Drive. The decrease in volumes caused delays to also decrease. Therefore, like the Approved Project, with implementation of Mitigation Measures 4.9-1, 4.9-3, and 4.9- 5 through 4.9-16 the Approved Project's impacts during the 2035 year would be less than significant. Mitigation Measure 4.9-3 would be modified to accommodate the proposed 4-legged roundabout with a signalized offset T-intersection with Placenta Canyon Road. Mitigation Measure 4.9-5 would be modified to accommodate the proposed upgrades and improvements at the 13th Street and Railroad Avenue intersection. Mitigation Measure 4.9-2 and 4.9-4 would no longer be applicable to Modified Project, as the Project does not include the extension of Lyons Avenue to Dockweiler Drive. Modifications to Mitigation Measures 4.9-3 and 4.9-5 are noted in by strikeout (deleted text) and underline (added text), below. These modifications would not result in new impacts or increase the severity of impacts above those which were previously analyzed under the Approved Project in the Final EIR.

As the Modified Project is generally consistent with the roadway improvements and configurations identified in the Final EIR for the Approved Project it is reasonable to assume that Modified Project would result in a similar number of railroad crossings at the Railroad Avenue and 13' Street as compared to the Approved Project. Therefore, it is reasonable to assume that the Modified Project's traffic impacts from railroad crossings would be similar as those identified for the Approved Project and would not result in new or more severe impacts as those analyzed in the Final EIR under the Approved Project. Bicycle and Pedestrian Facilities Additionally, as shown in Figure 2-10 the Modified Project would include a bicycle and pedestrian pathway and bridge south of Dockweiler Drive, that spans Newhall Creek, to connect with the northwest end of the Newhall Metrolink Station parking lot, located to the south of the proposed Dockweiler Drive extension. The additional bicycle and pedestrian access would promote non -auto travel and connectivity from Old Town Newhall and the Metrolink Station to The Master's University. Similar to the Approved Project, the Modified Project would comply with Santa Clarita's circulation goals and enhancing the circulation system by providing bicycle lanes and accessibility to bicycle paths that are fundamental for a comprehensive transportation network. Construction Traffic Construction of the Modified Project would require the addition of a temporary roadway along 13th Street between Railroad Avenue and Arch Street. The temporary roadway would provide a detour for vehicles during construction of the roadway improvements to 13th Street. The temporary roadway would be located on the north side of 13th Street, running parallel to 13th Street. The temporary roadway would be located within the Modified Project's limits. Implementation of Mitigation Measure 4.16 would require the submittal of a Construction Management Plan City of Santa Clarita Public Works Department (Traffic and Transportation Division) and LASD Santa Clarita Valley Station for review and approval prior to the commencement of any construction. The plans would show the location of any roadway or sidewalk closures, traffic detours, haul routes, hours of operation, protective devices, warning signs and access to abutting properties, and if applicable, the location of off -site staging areas for haul trucks and construction vehicles, and provide one or more emergency lane through the Project Site at all times. The County of Los Angeles Sheriff's Department Santa Clarita Valley Station shall receive advance notice priorto any changes in temporary lane closures or realignments. Therefore, impacts associated with construction traffic would be less than significant, similar to the Approved Project. Lyons Avenue/Dockweiler Drive Extension Project Addendum 4. Environmental Impact Analysis SCH No. 2013082016 Page 4-46 City of Santa Clarita May 2021 Vehicle Miles Traveled On January 20, 2016, the Governor's Office of Planning and Research released the Revised Proposal on Updates to the CEQA Guidelines on Evaluating Transportation Impacts in CEQA. In November 2018, the California Natural Resources Agency finalized the updates to the CEQA Guidelines and the updated guidelines became effective on December 28, 2018. Subsequent to the adoption of the Final EIR, on April 10, 2018, the City of Santa Clanta adopted transportation thresholds to adhere to the new CEQA transportation requirements and to implement SB 743. In an effort to reduce greenhouse gas (GHG) emissions, SB 743 changes the focus of transportation impact analysis in CEQA from measuring impacts based on vehicle delay, LOS and similar measurements of vehicular roadway capacity and traffic congestion as the basis for determining significant traffic impacts, to measuring the traffic impacts based on VMT. The justification for this paradigm shift is that auto delay/LOS impacts lead to improvements that increase roadway capacity and therefore induce more traffic and GHG emissions. As concluded in the Final EIR, the Approved Project is recognized as part of the regional strategy that is consistent with SCAG's policies to reduce VMTs." As the Modified Project is substantially consistent with the roadway alignment identified in the Final EIR for the Approved Project, the Modified Project would also be consistent with the City's Circulation Element as an additional route of travel connecting Railroad Avenue to Dockweiler Drive. Like the Approved Project, because no new land uses are being proposed, the Modified Project would not generate any new vehicle trips, but instead would provide an alternative and more direct route for motorists to get to and from their destination. As such, the Modified Project would not have the potential to increase VMTs on a per capita basis. Like the Approved Project, the Modified Project would include upgrades to the at -grade railroad crossing at the intersection of Railroad Avenue and 13t' street, new turn lanes, roadway widening, and median improvements. To improve traffic control, the Modified Project would also introduce a roundabout at the 12t'' Street/ Arch Street/ Dockweiler Drive intersection and modify the roadway connection from Dockweiler Drive to Placenta Canyon Road. These roadway improvements would improve traffic operations and enhance the safety of pedestrians and bicyclists. Additionally, the extension of Dockweiler Drive would promote non -auto travel by including a bicycle and pedestrian pathway south of Dockweiler Drive, that spans Newhall Creek, to connect with the northwest end of the Newhall Metrolink Station parking lot, located to the south of the proposed Dockweiler Drive extension. These improvements would provide connectivity from Old Town Newhall and the Metrolink Station to The Master's University.

Environmental Impact Analysis SCH No. 2013082016 Page 4-47 City of Santa Clarita May 2021 Project is exempt from requiring further VMT analysis.18 Impacts with respect to VMT would remain less than significant, similar to the Approved Project. 4.11 TRIBAL CULTURAL RESOURCES Approved Project As concluded in the Final EIR (see Section 4.4, Cultural Resources), the Approved Project would not have a direct impact upon known tribal cultural resources. Nevertheless, provisions for the identification and evaluation of accidentally discovered archeological resources would be implemented in accordance with Mitigation Measure 4.4-1. With the incorporation of Mitigation Measure 4.4-1, impacts upon tribal resources would be less than significant. Modified Project The southeastern grading limits for the Modified Project (between Arch Street and The Master's University project limits) are generally within the grading limits that were analyzed for both the Original Project and the Approved Project. The Modified Project would include a larger grading footprint on the northern portion of the Project Site (approximately seven acres), as compared to the Original Project and Approved Project, to accommodate the roadway improvements at Arch Street, 13th Street and Placerita Canyon Road, the intersection improvements at 13th Street and Railroad Avenue, grading improvements along the UP/Metrolink railroad line between 13th Street and 15th Street, and the addition of two new stormwater treatment basins. Like the Approved Project, provisions for the identification and evaluation of accidentally discovered archeological resources under the Modified Project would be implemented through Mitigation Measure 4.4-1, which would reduce impacts related to the accidental discovery of archeological resources to less than significant. Therefore, impacts related to tribal cultural resources would be the same as compared to the Approved Project. 4.12 WILDFIRE Approved Project Subsequent to the adoption of the Final EIR, the State CEQA Guidelines have been amended to require lead agencies to determine a project's potential risks to wildfires. A significant impact may occur if a project is located in proximity to wildland areas and poses a potential fire hazard, which could affect persons or structures in the area in the event of a fire, or exacerbate wildfire risk.

Environmental Impact Analysis SCH No. 2013082016 Page 4-48 City of Santa Clarita May 2021 Modified Project Like the Approved Project, the Modified Project includes the development of a roadway alignment. Although the Project Site is located within a very high fire hazard severity zone (VHFHSZ)19, the Modified Project does not include the construction of any habitable structures and would therefore not expose people or structures to significant risks associated with wildfire. Additionally, the Modified Project would be subject to the City's property development standards as specified in Chapter 17.51 of the Santa Clanta Municipal Code, which would require a fuel modification plan. The Modified project would also comply with applicable landscaping and brush abatement requirements for development within a VHFHSZ as determined by the Los Angeles County Fire Department. Therefore, with implementation of regulatory code compliance, impacts would be less than significant, and no further analysis of this issue is warranted. 19 State of California, Department of Forestry and Fire Protection (CAL FIRE).

Lyons Avenue/Dockweiler Drive Extension Project Addendum 4. Environmental Impact Analysis SCH No. 2013082016 Page 4-49 [Page left intentionally blank.] 5.0 IMPACTS DETERMINED TO BE LESS THAN SIGNIFICANT Like the Approved Project, it has been determined that there is no evidence that the Modified Project would cause significant environmental effects in the following areas discussed below, and that no further environmental review of these issues is necessary. This section contains an assessment and discussion of impacts associated with the environmental issues and subject areas identified in the Initial Study Checklist (Appendix G to the State CEQA Guidelines, (C.C.R. Title 14, Chapter 3, 15000-15387), as amended on January 1, 2019. 5.1 AGRICULTURAL RESOURCES The Project Site is zoned for a mix of commercial and residential uses; therefore, the Modified Project would not result in the conversion of Prime Farmland, Unique Farmland, or Farmland of Statewide Importance to a non-agricultural use. Additionally, there are no known Williamson Act Contract agreements associated with the Project Site. Therefore, like the Approved Project, the Modified Project would have no impact associated with the conversion of agricultural uses or forested lands. No further analysis of this issue is required. 5.2 GREENHOUSE GAS EMISSIONS As presented in the EIR, the City of Santa Clarita adopted a Climate Action Plan (CAP) on August 28, 2012, which provides policies and identifies actions intended to reduce GHG emissions within the City and assist in the fight against Climate Change. Overall, the goal of the CAP is to reduce Santa Clarita's community wide GHG emissions below the 2005 baseline emissions by 2020. The CAP includes a set of strategies the City can use to reduce the amount of greenhouse gas emissions produced in the community. Implementation of the measures proposed in the Proposed CAP would result in an annual community -wide reduction in GHG emissions of approximately 193,000 MTCO2e by 2020 from local measures and an additional reduction of approximately 148,952 MTCO2e by 2020 from statewide measures. This would reduce GHG emissions from the Business -as -usual projections for 2020 by 17 percent and would exceed the GHG reduction targets of 16 percent established by CARB in its revised scoping plan. Implementation of the strategies identified in the CAP would also exceed the City's goal to reduce 2020 GHG emissions to a level below the 2005 GHG emissions baseline by 4 percent. The CAP defines a local threshold of significance for greenhouse gas emissions (GHG) for project level submittals that are subject to environmental review under CEQA. Goals, objectives and policies approved under the General Plan are forecast to meet the GHG emission reduction targets mandated by AB 32. Therefore, development projects that are able to demonstrate consistency with the General Plan and zoning ordinance are by association consistent with the CAP and are not subject to further environmental review. Development proposals that are not consistent with the City's General Plan and/or Unified Development Code (Zone Changes/General Plan Amendments) must demonstrate a 12 percent reduction in the GHG emissions from the Controlled 2020 Business as Usual Scenario, to be deemed consistent with the CAP. Development proposals that are not consistent with the City's General Plan and/or Unified Development Lyons Avenue/Dockweiler Drive Extension Project Addendum 5. Impacts Determined To Be Less Than Significant SCH No. 2013082016 Page 5-1 City of Santa Clarita May 2021 Code and that cannot demonstrate a 12 percent reduction in GHG emissions from the Controlled Business as Usual Scenario shall be deemed to have a significant impact on GHG emissions. Like the Approved Project, the Modified Project is consistent with the Circulation Element of the General Plan and will not require a zone change or General Plan amendment. As such, the Modified Project's potential to generate GHGs will be less than significant with respect to consistency with all applicable plans, policies or regulations adopted for the purpose of reducing the emissions of greenhouse gases, and no further analysis of this issue is warranted. 5.3 HAZARDS AND HAZARDOUS MATERIALS Like the Approved Project, the Modified Project would not require the transport, use, and/or disposal of potentially hazardous materials, the potential for an impact to occur is considered low. In addition, no properties within or immediately adjacent to the Project Site appear on the State's list of hazardous materials sites. Therefore, further analysis of this issue is not warranted. 5.4 MINERAL RESOURCES There are no known economic mineral resources located beneath the Project Site. The Project Site is not within a known source area for aggregate or other mineral resources. Additionally, the Project Site is not located in an area of potential petroleum resources. Therefore, development of the Modified Project would not result in the loss of availability of a known mineral resource that would be of value to the region and the residents of the state. The Modified Project would not result in any potentially significant impacts to mineral resources and no further analysis of this issue is warranted. 5.5 POPULATION AND HOUSING Similar to the Approved Project, the Modified Project involves the buildout of a proposed roadway alignment that was identified within the City's Circulation Element of the General Plan. No residential, commercial, or industrial land uses are proposed. Therefore, the Modified Project would not have the potential to induce substantial population growth in the area. As such, the Modified Project would not significantly impact the existing housing stock. Additionally, the Modified Project would not displace any existing housing units, necessitating the construction of replacement housing elsewhere. Therefore, no impact would occur and no further analysis is required. 5.6 PUBLIC SERVICES Like the Approved Project, the Modified Project would not directly increase the demands for fire and police protection as the Modified Project does not include any new housing units or commercial uses. Emergency access to the Placenta Canyon community would be facilitated through the Project's alignment, which is consistent with the City's adopted Circulation Element. The Project's alignment would be an improvement to the current access route into the Placerita Canyon community via 13th Street. The upgrade of the 13th Street at -grade crossing is a proposed safety feature aimed at reducing potential conflicts between Lyons Avenue/Dockweiler Drive Extension Project Addendum 5. Impacts Determined To Be Less Than Significant SCH No. 2013082016 Page 5-2 City of Santa Clarita May 2021 pedestrians, vehicles and trains. The Modified Project's impact upon fire and police services would be less than significant and no further analysis is warranted. Like the Approved Project, there are no residential properties on the Project Site and none are planned as part of the development of the Modified Project. Therefore, development of the Modified Project would not result in a direct increase in the resident population which would in turn not result in any increase demand for schools, parks, recreational facilities, libraries or other governmental facilities. Therefore, with respect to local schools, park, recreation, libraries and other governmental facilities, no impact would occur, and no further analysis of this issue is warranted. 5.7 UTILITIES Construction The Modified Project's construction activities would require the conveyance of water for dust suppression activities during the demolition/grading/excavation phases. However, due to the relatively short duration of construction, water consumption and impacts to water conveyance infrastructure would not be considered excessive or substantial. Additionally, as discussed further in Section 4.5, Energy, of this Addendum, energy demands during construction would be typical of construction projects of this size and nature, and would not necessitate additional long-term energy facilities or distribution infrastructure, or cause wasteful, inefficient or unnecessary consumption of energy. Lastly, the temporary duration and scope of construction activities associated with the Modified Project would not result in a substantial increase in wastewater or solid waste generation, nor require telecommunication resources. Therefore, impacts related to the demand, and or consumption, of the aforementioned resources and facilities, would be less than significant. Operation Like the Approved Project, the Modified Project includes the development of a roadway alignment. The Modified Project does not include the development of residential, commercial or industrial uses. As such, during operation, the Modified Project's demand for potable water would be limited to landscaping associated with the roadway improvements and would be subject to applicable State and City regulatory code compliance for water consumption and conservation. Irrigation would ultimately connect to the City's expanding recycled water pipeline system. As such the Modified Project's limited use of potable water for landscaping would not be considered excessive or substantial and operational water demand on local water supplies and conveyance would be less than significant. With respect to runoff discharge and stormwater drainage associated with the Modified Project, as discussed further in Section 4.7 Hydrology, of this Addendum, the Modified Project would include the addition of two basins for stormwater capture and treatment associated with the roadway improvements. The Modified Project would be required to have a Project -specific SUSMP in place during its operational life to address the management of runoff from the roadway extension in accordance with NPDES requirements. With implementation of the stormwater quality plans and regulatory code compliance as discussed in Section 4.7 Lyons Avenue/Dockweiler Drive Extension Project Addendum 5. Impacts Determined To Be Less Than Significant SCH No. 2013082016 Page 5-3 City of Santa Clarita May 2021 Hydrology, of this Addendum, impacts to stormwater drainage facilities during operation would be less than significant. Lastly, operation of the Modified Project would not create demand for solid waste resources, telecommunications and natural gas services, or generate wastewater, and would therefore have no impact to these facilities or systems. As presented in the Final EIR (see Section 2. Additions and Corrections to the EIR, pg. 2-2), the Modified Project would include MM 5.1-1 to ensure that locations of buried utility -owned lines are marked prior to commencement of excavation work for the Modified Project. Additionally, MM 5.1-2 would ensure that the abandonment and/or relocation and/or modification of any portion of an existing natural gas lines would be coordinated with Southern California Gas Company. Therefore, like the Approved Project, impacts associated with the Modified Project, with respect to utilities, would be less than significant and no further analysis is warranted.

INTRODUCTION A. PURPOSE OF THIS ADDENDUM The purpose of this Addendum to the 2018 Lyons Avenue/Dockweiler Drive Extension Project Final Environmental Impact Report (2018 Dockweiler FEIR) is to evaluate the environmental effects associated with the relocation, construction, and operation of the Placerita Maintenance Yard (Proposed Project). The Proposed Project would involve the relocation of an existing County -owned maintenance yard from its current location at 22234 Placerita Canyon Road in the City of Santa Clarita (within the area analyzed in 2018 Dockweiler FEIR) to a new location at 15601 Norland Drive, also within the Santa Clarita Valley. The relocated Placerita maintenance yard would accommodate the same uses and activities as the existing maintenance yard. Under the Proposed Project, the County would vacate the maintenance yard located at 22234 Placerita Canyon Road and move to the Norland Drive site (to be acquired from the City). The relocation is necessary to accommodate the City's roadway improvement project.1 Los Angeles County Public Works (County) currently uses 22234 Placerita Canyon Road as a maintenance yard. This existing maintenance yard is owned by the County of Los Angeles. As described below, in 2018, the City of Santa Clarita approved roadway improvements that will require the vacation of the Placerita Canyon maintenance yard to allow for the development of the City's roadway project. The City has proposed 15601 Norland Drive as a new location for the County's maintenance yard. The City has proposed the sale of the 15601 Norland Drive, Santa Clarita to the County and the County has displayed interest in acquiring the property. The 15601 Norland Drive site was not evaluated as part of the 2018 Dockweiler FEIR. With the relocation of the County's maintenance yard to 15601 Norland Drive, the Project Site, as described in the 2018 Dockweiler EIR, is modified. The Project Site now includes the area evaluated 2018 Dockweiler FEIR and the 15601 Norland Drive site. The Placerita Canyon maintenance yard is within the boundary of the area evaluated in the City's 2018 Dockweiler FEIR, which was certified April 10, 2018, for the Lyons Avenue/Dockweiler Drive Extension Project.2,3 The 2018 Dockweiler FEIR, evaluated the extension of Lyons Avenue from Railroad Avenue to the future connection with Dockweiler Drive (Original Project). The City' s Original Project would include 2018 FEIR, Figure 2-9 shows that the approved extension of Dockweiler Drive as a part of the Lyons Avenue/Dockweiler Drive Extension Project would traverse 2223 Placerita Canyon Road. Therefore, the County's maintenance yard must be relocated to accommodate the approved extension. City of Santa Clarita, City of Santa Clarita Agenda Report.

City of Santa Clarita, Lyons Avenue/Dockweiler Drive Extension Project Final Environmental Impact Report, February 2018. Available online at: hM2s://santaclarita.gov/capital-improvement-projects/proposed-dockweiler-drive- extension/, accessed August 9, 2024 Impact Sciences, Inc. 1 Placerita Yard Relocation Project 1250.020 Lyons Avenue/Dockweiler Drive Extension Final EIR 2nd Addendum 1. Introduction re -profiling the intersection of Lyons Avenue and Railroad Avenue to allow the construction of a new Southern California Regional Rail Authority (SCRRA) / Union Pacific railroad grade crossing. The Original Project would also include the potential upgrade or closure of an at -grade crossing at the intersection of Railroad Avenue and 1311, Street. Further, the installation of intersection improvements at the Arch Street / 1211, Street / Placerita Canyon and proposed Dockweiler Drive alignment is also proposed as part of the Original Project. Three intersection improvements were analyzed and approved in the 2018 Dockweiler FEIR (Options A through C), all three options traverse the Placerita Canyon maintenance yard. As a result, the City will need to acquire the site from the County. In addition to the three options considered as part of the 2018 Dockweiler FEIR, four alternatives to the Original Project were also analyzed: No Project, Alternative 1 Project (Proposed Alignment with the 13th Street Rail Crossing), Alternative 2 Project (Proposed Alignment to Arch Street without Lyons at Grade Crossing) and the Market Street Alignment. Of the alternatives evaluated, the Alternative 2 Project was selected as the Environmentally Superior Alternative, as it would reduce the footprint of the Project Site, as it excludes the Lyons Avenue Extension to Dockweiler Drive and maintains the at -grade crossing at 13th Street. With its selection, Alternative 2 became the Approved Project. The Approved Project would involve the development of the proposed roadway alignment and associated infrastructure for Dockweiler Drive, which would extend Dockweiler Drive to Arch Street. The route would continue along Arch Street to 13th Street to link to Railroad Avenue. Unlike the Original Project, the Approved Project does not include the roadway segment between the Dockweiler extension and Lyons Avenue, which spans a portion of Newhall Creek. Additionally, the Approved Project proposes to maintain and improve the 13th Street rail crossing. At the intersection of Arch Street, 12th Street, Placerita Canyon and Dockweiler Drive would be improved with one of three intersection design configurations under the Approved Project. The Approved Project will require the acquisition of several parcels, including the parcel which is the site of the County's Placerita maintenance yard. Under separate cover, the City has indicated that it is currently preparing an addendum to the 2018 FEIR which analyzes a proposed extension of Dockweiler Drive from its existing terminus westward to intersect Arch Street and 131h Street. The existing median nose on Railroad Avenue would be removed to reconfigure the four southbound lanes to provide two protected left turn lanes, one dedicated through lane and one shared right turn lane and through lane. Additionally, a new pedestrian and bicycle bridge would cross over Newhall Creek to connect with the northwest end of the Newhall Metrolink Station parking lot. Similar to the Approved Project, the proposed modifications propose a four -legged roundabout with a signalized offset T-intersection with Placerita Canyon Road, which would require the acquisition of the County's Placerita maintenance yard. It should be noted that the City's addendum is currently under Impact Sciences, Inc. 2 Placerita Yard Relocation Project 1250.020 Lyons AvenuelDockweiler Drive Extension Final EIR 2nd Addendum 1. Introduction review by the City and has not been formally approved; therefore, any changes to the Approved Project have not been implemented at this time and the analysis within this Addendum is appropriately based on the Approved Project. Because the County is proposing to acquire 15601 Norland Drive from the City, the purpose of this Addendum is to evaluate potential environmental impacts that may occur as a result of the transfer of the property and the resulting proposed relocation of the Placerita maintenance yard to 15601 Norland Drive (Proposed Project).. Because the proposed relocation is a reasonably foreseeable consequence of the Approved Project, an addendum to the 2018 Dockweiler FEIR is being prepared. As demonstrated in detail herein, the changes associated with the Proposed Project would not trigger any of the conditions identified in Section 15162 of the State CEQA Guidelines calling for the preparation of a subsequent EIR or negative declaration (see Section B, below). Construction and operation of the Proposed Project would be required to comply with applicable mitigation measures identified in the 2018 Dockweiler FEIR and adopted by the City of Santa Clarita. Furthermore, as the Project Site is located within the Santa Clarita Valley, and because the Proposed Project would be consistent with its land use designation under the Santa Clarita Valley Area Plan, mitigation in the One Valley One Vision Final Environmental Impact Report (2011 OVOV FEIR), the programmatic EIR of the Santa Clarita Valley Area Plan, would also be applied to the Proposed Project.4,5 The Santa Clarita Valley Area Plan is a component of the County's General Plan and a joint effort between the County of Los Angeles and the City of Santa Clarita to create a programmatic document with a set of guidelines for the future growth of the Santa Clarita Valley and the preservation of natural resources. The Santa Clarita Valley Area Plan encompasses the jurisdiction of the City of Santa Clarita and all unincorporated areas of the County of Los Angeles within the Santa Clarita Valley. The 2011 OVOV EIR analyzed the environmental impacts of the implementation of the OVOV per Sections 15091 and 15092 of the State CEQA Guidelines and is the EIR that was certified for the Santa Clarita Valley Area Plan. City of Santa Clarita, One Valley One Vision Final Environmental Report, May 2011. Available online at: hUs://santaclarita. gov/planning/environmental-impact-reports-completed/one-valley-one-vision-general-plan/, accessed August 9, 2024. The One Valley One Vision Plan and associated EIR was adopted by the County Board of Supervisors on November 27, 2012, and took effect on December 27, 2012. The County portion of the plan is known as the Santa Clarita Valley Area Plan; however, the same EIR was certified for both plans. Impact Sciences, Inc. 3 Placerita Yard Relocation Project 1250.020 Lyons Avenue/Dockweiler Drive Extension Final EIR 2nd Addendum 1. Introduction B. CEQA REQUIREMENTS AND REVISIONS TO CEQA GUIDELINES CEQA Requirements with Respect to Preparation of an Addendum An Addendum to an EIR is the appropriate tool to evaluate the environmental effects associated with minor modifications to previously approved projects. It is appropriate when proposed modifications to a previously approved project would not result in new or increased significant adverse impacts. According to Section 15164(a) of the State CEQA Guidelines, "the lead agency or a responsible agency shall prepare an addendum to a previously certified EIR if some changes or additions are necessary but none of the conditions described in Section 15162 calling for preparation of a subsequent EIR have occurred." An addendum may be prepared if only minor technical changes or additions are necessary. A brief explanation of the decision not to prepare a subsequent EIR must also be provided in the addendum, findings or the public record. Section 15162 of the State CEQA Guidelines lists the conditions that would require the preparation of a subsequent EIR or negative declaration rather than an addendum. These include the following: Substantial changes are proposed in the project which will require major revisions of the previous EIR or negative declaration due to the involvement of new significant environmental effects or a substantial increase in the severity of previously identified significant effects; Substantial changes occur with respect to the circumstances under which the project is undertaken which will require major revisions of the previous EIR or negative declaration due to the involvement of new significant environmental effects or a substantial increase in the severity of previously identified significant effects; or 3. New information of substantial importance which was not known and could not have been known with the exercise of reasonable diligence at the time the previous EIR was certified as complete or the negative declaration was adopted, shows any of the following: A. The project will have one or more significant effects not discussed in the previous EIR or negative declaration; B. Significant effects previously examined will be substantially more severe than shown in the previous EIR; C. Mitigation measures or alternatives previously found not to be feasible would in fact be feasible, and would substantially reduce one or more significant effects of the project, but the project proponents decline to adopt the mitigation measures or alternative; or D. Mitigation measures or alternatives which are considerably different from those analyzed in the previous EIR would substantially reduce one or more significant effects on the environment, but the project proponents decline to adopt the mitigation measure or alternative. Impact Sciences, Inc. 4 Placerita Yard Relocation Project 1250.020 Lyons AvenuelDockweiler Drive Extension Final EIR 2nd Addendum 1. Introduction Unlike a subsequent EIR, per Section 15162, a supplement to an EIR may be prepared per Section 15163 under the following conditions. (a) The Lead or Responsible Agency may choose to prepare a supplement to an EIR rather than a subsequent EIR if. (1) Any of the conditions described in Section 15162 would require the preparation of a subsequent EIR, and (2) Only minor additions or changes would be necessary to make the previous EIR adequately apply to the project in the changed situation. A supplement to an EIR may be distinguished from a subsequent EIR by the following: a supplement augments a previously certified EIR to the extent necessary to address the conditions described in Section 15162 and to examine mitigation and project alternatives accordingly. It is intended to revise the previous EIR through supplementation. A subsequent EIR, in contrast, is a complete EIR, which focuses on the conditions described in Section 15162. The currently Proposed Project is described in Section 2 of this Addendum. The Proposed Project has been reviewed by the County of Los Angeles in light of Sections 15162, 15163 and 15164 of the State CEQA Guidelines. As the CEQA Lead Agency, the County of Los Angeles has determined, based on the analysis presented herein, that none of the conditions apply which would require preparation of a subsequent or supplemental EIR and that an Addendum to the certified 2018 Dockweiler FEIR is the appropriate environmental documentation under CEQA for the Proposed Project. Section 3 discusses issue -by -issue how the impacts anticipated for the Proposed Project would be within those previously identified in the 2018 Dockweiler FEIR. The Mitigation Monitoring and Reporting Program (MMRP), Findings, and Statement of Overriding Considerations were adopted with the 2018 Dockweiler FEIR as it was certified on April 10, 2018. The MMRP would continue to apply to the Proposed Project to ensure that all significant impacts remain less than significant where it is feasible to mitigate such impacts. Revisions to State CEQA Guidelines The California Natural Resources Agency adopted revisions to the State CEQA Guidelines that became effective on December 28, 2018. The Notice of Preparation for the Lyons Avenue/Dockweiler Drive Extension Project was released August 5, 2013, and the Draft EIR was published August 16, 2017. While the Final EIR was certified in 2018, EIR preparation occurred well in advance of the revisions to the State CEQA Guidelines and, as a result, many of the changes were not addressed within the 2018 Dockweiler FEIR. The most recent State CEQA Guidelines Appendix G is used in this document, as it is the latest Impact Sciences, Inc. 5 Placerita Yard Relocation Project 1250.020 Lyons AvenuelDockweiler Drive Extension Final EIR 2nd Addendum 1. Introduction checklist reflecting a clearer organization of issues; the changes did not add topics compared to what was evaluated in the 2018 Dockweiler FEIR, rather topics are reorganized and clarified. As each topic is discussed in Section 3, the analysis notes where each topic was discussed in the 2018 Dockweiler FEIR. C. ADOPTED MITIGATION MEASURES The 2018 Dockweiler FEIR identified the mitigation measures shown in Table 1. These measures have been reviewed and selected as applicable to both the Approved Project and the Proposed Project and were included in the Mitigation Monitoring and Reporting Program (MMRP) adopted by the City of Santa Clarita along with certification of the FEIR on April 10, 2018. Table 1 Adopted Mitigation Measures 2018 Dockweiler FEIR Aesthetics 4.1-1. Construction equipment, debris, and stockpiled equipment shall be visually screened to effectively block the line -of -sight from the ground level neighboring residential properties. Such barricades or enclosures shall be maintained in appearance throughout the construction period. Graffiti shall be removed immediately upon discovery. 4.1-2 The roadway median and contoured slopes along then roadway alignment shall be attractively landscaped and maintained in accordance with landscape plans to the satisfaction of the City Planning Department Air Quality 4.2-1: Prior to grading permit issuance, the Project contractor shall develop a Construction Emission Management Plan to minimize construction -related emissions. The Construction Emission Management Plan shall require the use of Best Available Control Measures, as specified in Table 1 of SCAQMD's Rule 403. The Construction Emission Management Plan shall include the following additional elements: a) Use of water trucks or sprinkler systems in sufficient quantities to prevent airborne dust from leaving the site. When wind speeds exceed 15 miles per hour the operators shall increase watering frequency. b) Active sites shall be watered at least three times daily during dry weather. c) Suspend grading and excavation activities during windy periods (i.e., surface winds in excess of 25 miles per hour). d) Suspend the use of all construction equipment during first -stage smog alerts. E e) Application of non -toxic chemical soil stabilizers or apply water to form and maintain a crust on inactive construction areas (disturbed lands within construction projects that are unused for at least four consecutive days). f) Application of non -toxic binders to exposed areas after cut and fill operations and hydroseeded areas. g) Plant vegetative ground cover in disturbed areas as soon as possible and where feasible. h) Operate street sweepers that comply with SCAQMD Rules 1186 and 1186.1 on roads adjacent to the construction site so as to minimize dust emissions. Paved parking and staging areas shall be swept daily. Schedule truck deliveries to avoid peak hour traffic conditions, consolidating truck deliveries, and prohibiting truck idling in excess of 5 minutes. i) Reduce traffic speeds on all unpaved roads to 15 miles per hour or less. k. Pave or apply gravel on roads used to access the construction sites when possible. j) Minimize idling time either by shutting equipment when not in use or reducing the time of idling to 5 minutes as a maximum. m. Limit, to the extent feasible, the hours of operation of heavy-duty equipment and/or the amount of equipment in use. 4.2-2: All off -road diesel -powered construction equipment greater than 50 hp shall meet the Tier 4 emission standards, where available. In addition, all construction equipment shall be outfitted with BACT devices certified by CARB. Any emissions control device used by the contractor shall achieve emissions reductions that are no less than what could be achieved by a Level 3 diesel emissions control strategy for a similarly sized engine as defined by CARB regulations. A copy of each unit's certified tier specification, BACT documentations, and CARB, SCAQMD, or ICAPCD operating permit shall be provided at the time of Impact Sciences, Inc. 6 Placerita Yard Relocation Project 1250.020 Lyons Avenue/Dockweiler Drive Extension Final EIR 2nd Addendum 1. Introduction mobilization of each applicable unit of equipment. 4.2-3: An information sign shall be posted at the entrance to each construction site that identifies the permitted construction hours and provides a telephone number to call and receive information about the construction project or to report complaints regarding excessive fugitive dust generation. Any reasonable complaints shall be rectified within 24 hours of their receipt. 4.2-4: The contractor shall utilize low-VOC content coatings and solvents that are consistent with applicable SCAQMD and ICAPCD rules and regulations. Biological Resources 4.3-1: The applicant shall retain a qualified biologist with a CDFG Scientific Collection Permit and Memorandum of Understanding to conduct preconstruction surveys for the silvery legless lizard within the Project Site and area. Should this species be located on the Project Site during preconstruction surveys all individuals shall be relocated, with the concurrence of the City and CDFW, to an approved site with suitable habitat. Surveys and relocation of silvery legless lizard may occur prior to construction; however, focused surveys must occur within 30 days prior to construction. Survey and relocation methods shall be approved by CDFW prior to commencement of grading. 4.3-2: Active nests of native bird species are protected by the Migratory Bird Treaty Act (16 U.S.C.704) and the California Fish and Game Code (Section 3503). If activities associated with construction or grading are planned during the bird nesting/breeding season, generally January through March for early nesting birds (e.g., Coopers hawks or hummingbirds) and from mid -March through September for most bird species, the applicant shall have a qualified biologist conduct surveys for active nests. The project management shall endeavor to avoid the breeding season. In the event it is not feasible to avoid the nesting season, a qualified biologist shall perform weekly nesting bird surveys beginning 30 days prior to initiation of ground -disturbing activities, with the last survey conducted no more than three days prior to the start of clearance/construction work. If ground disturbing activities are delayed, additional preconstruction surveys shall be conducted so that no more than three days have elapsed between the survey and ground -disturbing activities. Surveys shall include examination of natural habitat for nesting birds. Several bird species such as killdeer and night hawks are known to nest on bare ground. Protected bird nests that are found within the construction zone shall be protected by a buffer deemed suitable by a qualified biologist and verified by CDFW. Typically, a 300-foot buffer is required for most species and a 500-foot buffer for raptor species. Buffer areas shall be delineated with orange construction fencing or other exclusionary material that would inhibit access within the buffer zone. Installation of the exclusionary material delineating the buffer zone shall be verified by a qualified biologist prior to initiation of construction activities. The buffer zone shall remain intact and maintained while the nest is active (i.e., occupied or being constructed by the adult bird(s)) and until young birds have fledged and no continued use of the nest is observed, as determined by a qualified biologist. 4.3-3: Prior to project construction, the following is required to mitigate impacts to jurisdictional resources: a. Areas of impact proposed by the project shall be calculated and permits for these proposed impacts shall be obtained (the discharge of fill into ACOE jurisdictional areas will require a permit pursuant to Section 404 of the Clean Water Act and a 401 Certification from the State Water Resources Control Board, and any modification to a streambed, [analysis states none is present], will require a streambed alteration agreement from CDFW pursuant to Section 1600 of the California Fish and Game Code). Both the streambed alteration agreement and the 401 and 404 permits will require specific mitigations for any impacts within their respective jurisdictions. b. Because the proposed bridge is a 'span' design, it does not require footings within the bed of the stream. However, plan designs do include approximately 450 feet of bank stabilization on both sides of the stream that would lie within CDFW, ACOE and Regional Water Quality Control Board jurisdiction. Since little vegetation exists within this drainage, it is uncertain what mitigation these regulatory agencies may require. C. The stream in the impacted area would not be conducive to re -vegetation as the area of the project is deeply incised with little existing vegetation and newly planted vegetation would likely be washed away with the next storm event. d. Mitigation can be completed off site. Because there is essentially no riparian vegetation being removed with implementation of this project, revegetation off site, in a location approved by the City and CDFW, would be accomplished at a 1:1 area ratio. e. Upon City and agency approval of a suitable location, a detailed restoration plan shall be prepared that provides a planting palette, planting methods, and irrigation plan (as appropriate). The plan will also include a 5-year monitoring effort to ensure success of the restoration effort. The monitoring plan will include monitoring methods, monitoring frequency, success criteria, and contingency actions should the success criteria not be met for any reason. Annual monitoring reports shall be provided to both CDFW and the City. Impact Sciences, Inc. 7 Placerita Yard Relocation Project 1250.020 Lyons Avenue/Dockweiler Drive Extension Final EIR 2nd Addendum 1. Introduction 4.3-4: The following guidelines shall be implemented to minimize impacts on remaining biological resources on the site as a result of construction and grading activities and to ensure that potential impacts on these resources will remain less than significant. A City -approved biologist shall be retained by the applicant as a construction monitor to ensure that incidental construction impacts on retained biological resources are avoided or minimized. Responsibilities of the construction monitor shall include the following: • Attend all pre -grading meetings to ensure that the timing and location of construction activities do not conflict with mitigation requirements. • Conduct meetings with the contractor and other key construction personnel, describing the importance of restricting work to within the project boundaries and outside of the preserved areas. The monitor shall also work with the contractor to determine the most appropriate staging/storage areas for equipment and materials. • Guide the contractor in marking/flagging the construction area limits, in accordance with the final approved grading plan. • Periodically and routinely visit the site during construction to coordinate and monitor compliance with the above provisions. The construction contractor shall install temporary erosion control measures to reduce impacts to and protect on site drainages from excess sedimentation, siltation, and erosion. These measures shall consist of minimization of existing vegetation removal; the use of temporary soil covers, such as hydroseeding with native species, mulch/binder and erosion control blankets to protect exposed soil from wind and rain erosion; and/or the installation of silt fencing, berms, and dikes to protect storm drain inlets and drainages. No changing of oil or other fluids or discarding of any trash or other construction waste materials shall occur on the Project Site. Vehicles carrying supplies, such as concrete, shall not be allowed to empty, clean out, or otherwise place materials into natural areas on or immediately adjacent to the site. Any equipment or vehicles driven and/or operated within or adjacent to drainages shall be checked and maintained daily, to prevent leaks of materials that if introduced to water could be deleterious to aquatic life. No equipment maintenance shall be conducted within the drainage channels or within 50 feet of channels. (Fuel -powered vehicles and equipment shall not be left idling or operated beyond periods needed to accomplish approved tasks.) Construction personnel shall be prohibited from entry into areas outside the designated construction area, except for necessary construction related activities, such as surveying. All such construction activities in or adjacent to remaining open space areas shall be coordinated with the project biologist. Standard dust control measures of the South Coast Air Quality Management District shall be implemented to reduce impacts on nearby plants and wildlife. This includes a variety of options to reduce dust including replacing ground cover in disturbed areas as quickly as possible, watering active sites regularly, and suspending all excavating and grading operations during periods of high winds. Upon completion of construction, the contractor shall be held responsible for restoring any haul roads, access roads, or staging areas that are outside of approved grading limits. This restoration shall be done in consultation with the project biologist. 4.3-5: Any landscaping plan(s) associated with the project shall be reviewed by a qualified biologist or resource specialist, who shall recommend appropriate provisions to prevent invasive plant species from colonizing in natural areas. These provisions may include the following: (a) review and screening of proposed plant palette and planting plans to identify and avoid the use of invasive species; (b) weed removal during the initial planting of landscaped areas; and (c) the monitoring for and removal of weeds and other invasive plant species as part of ongoing landscape maintenance activities. 4.3-6: All street lighting shall be downcast luminaries or directional lighting with light patterns directed away from natural areas. 4.3-7: Prior to issuance of a grading permit, an Oak tree report shall be prepared and approved. All oaks that will not be removed that are regulated under the City of Santa Clarita's Oak Tree Preservation and Protection Guidelines with driplines within 50 feet of land clearing (including brush clearing) or areas to be graded shall be enclosed in a temporary fenced zone for the duration of the clearing or grading activities. Fencing shall extend to the root protection zone (i.e., the area at least 15 feet from the trunk or 5 feet beyond the drip line, whichever distance is greater). No parking or storage of equipment, solvents, or chemicals that could adversely affect the trees shall be allowed within 25 feet of the trunk at any time. Removal of the fence shall occur only after the project arborist or qualified biologist confirms the health of preserved trees. Cultural Resources 4.4-1: In the event any archaeological materials are encountered during the course of Project development, all construction activity shall halt in the area of the find and the services of a qualified archaeologist shall be secured to assess the discovered material(s) and prepare a survey, study or report evaluating the significance of the materials encountered. The archaeologist's written assessment shall contain a detailed description of the materials encountered, and recommendations, if necessary, for the preservation, Impact Sciences, Inc. 8 Placerita Yard Relocation Project 1250.020 Lyons Avenue/Dockweiler Drive Extension Final EIR 2nd Addendum 1. Introduction conservation, or relocation of the resource. Project development activities may resume once copies of the archaeological survey, study or report are submitted to the satisfaction of the Planning Director and copies distributed to the SCCIC Department of Anthropology 4.4-2: In the event any suspected paleontological materials are encountered during the course of Project development, all construction activity shall halt in the area of the find and the services of a qualified paleontologist shall be secured to assess the discovered material(s) and prepare a survey, study or report evaluating the significance of the materials encountered. The paleontologist's written assessment shall contain a detailed description of the materials encountered, and recommendations, if necessary, for the preservation, conservation, or relocation of the resource. Project development activities may resume once copies of the paleontological survey, study or report are submitted to the satisfaction of the Planning Director and copies distributed to the Los Angeles County Natural History Museum. Geology and Soils 4.5-1: The Proposed Project shall be designed and constructed in accordance with the City and State Building Codes and shall adhere to all modern earthquake standards, including the recommendations provided in the Project's Geotechnical Report, which shall be reviewed by the Division of the City's Building and Safety Division 4.5-2: Prior to the issuance of a grading permit, the Applicant shall provide grading plans to the City's Building and Safety Division for review and approval. Grading plans shall comply with the City's requirements for slope stability. Grading plans shall also comply with City requirements for stability under static and pseudo static loading conditions to mitigate risks associated with earthquake induced landslides. Noise 4.8-1: Pursuant to Section 11.44.080 of the City's Noise Ordinance, no construction work shall occur within 300 feet of occupied residences except between the hours of 7:00 AM and 7:00 PM Monday through Friday, and between 8:00 AM and 6:00 PM on Saturday. No construction work shall occur on Sunday, New Year's Day, Independence Day, Thanksgiving Day, Christmas Day, Memorial Day, and Labor Day. 4.8-2: The construction schedule (including the various types of activities that would be occurring throughout the duration of construction phases, anticipated truck routes, and the potential for noise impacts along local roadways from construction related vehicles) shall be prominently posted on -site during construction stages. When construction activities are anticipated to occur within 200 feet of residences, notice of the construction schedule shall be mailed to such residences two weeks prior to commencement of activity. 4.8-3: The phone number of the job superintendent shall be clearly posted at all construction entrances to allow for surrounding owners and residents to contact the job superintendent. If the job superintendent receives a complaint, the superintendent shall investigate, take appropriate corrective actions, and report the action taken to the reporting party. Contract specifications shall be included in the Project's construction document. 4.8-4: All internal combustion engine construction equipment shall be properly muffled or equipped with other noise attenuating devices capable of achieving a sound attenuation of at least 3 dB(A) at 50 feet of distance. Such equipment shall also be in good working condition. 4.8-5: As feasible, construction activities shall use specially quieted equipment, such as electric air compressors and similar power tools, rather than diesel equipment. 4.8-6: Construction staging areas shall be located away from sensitive land uses, particularly away from single-family residences near Dockweiler Drive's current western terminus, single-family residences near Deputy Jake Drive's western cul-de-sac, single-family residences near Market Street and Race Street, and existing on -site dormitories. 4.8-7: Construction and grading activities shall be scheduled in such a way so as to avoid operating several pieces of equipment simultaneously, which causes high noise levels. 4.8-8: Construction activities whose specific location on the site may be flexible (e.g., operation of compressors and generators, cement mixing, general truck idling) shall be conducted as far as possible from the nearest noise -sensitive land uses, particularly away from single-family residences. 4.8-9: Temporary construction noise barriers of sufficient height shall be erected in such a way so as to disrupt line -of -sight between the active construction noise sources and any residences within 500 feet of the Project Site.

Source: 2018 Dockweiler FEIR Relationship to the One Valley One Vision EIR As mentioned above, 15601 Norland Drive is located outside the area reviewed as part of the Lyons Ave / Dockweiler Extension project. However, the entirety of the Project Site, including the Norland Drive site, is located within the Santa Clarita Valley Area Plan Planning Area. The Santa Clarita Valley Area Plan is a joint effort between the City, the County, and Santa Clarita Valley (Valley) residents and businesses to create a single vision and guidelines for the future growth of the Valley and the preservation of natural resources. Realizing that development within both jurisdictions can have regional implications, the City and County jointly endeavored to prepare planning policies and guidelines to guide future development within the Valley. As a result of the effort two separate documents were adopted. The City adopted a new General Plan Element and EIR to update the City's 1991 General Plan, while the County adopted a new Santa Clarita Valley Area Plan to replace the 1990 Santa Clarita Valley Area Plan. The Santa Clarita Valley Area Plan became a part of the County's General Plan upon adoption. The City adopted the One Valley One Vision Plan and certified the EIR on June 14, 2011. The County adopted the Santa Clarita Valley Area Plan (Area Plan) and certified the OVOV EIR on November 27, 2012. Both planning documents used the same EIR, the 2011 OVOV EIR that is referenced throughout this Addendum. Impact Sciences, Inc. 11 Placerita Yard Relocation Project 1250.020 Lyons Avenue/Dockweiler Drive Extension Final EIR 2nd Addendum 1. Introduction The 2011 OVOV FEIR evaluates the potential impacts of the goals, objectives, and policies of the Area Plan. The 2011 OVOV EIR is a Program EIR that evaluates the broad -scale impacts of the Area Plan. A Program EIR, addressing the potential impacts of the City's goals, objectives, and policies can be thought of as a "first tier" document. It evaluates the large-scale impacts on the environment that can be expected to result from the adoption of the Area Plan but does not necessarily address the site -specific impacts that each of the individual development projects that will follow may have. CEQA requires each of those subsequent development projects to be evaluated for their site -specific impacts. These site -specific analyses are typically encompassed in second -tier documents, such as project EIRs, focused EIRs, and mitigated negative declarations on individual development projects subject to the General Plan, which typically evaluate the impacts of a single activity undertaken to implement the overall plan. The program EIR can be incorporated by reference into subsequent documents to focus on new or site -specific impacts. As part of the EIR process, the County adopted the policies and mitigation measures included in the 2011 OVOV Final EIR. State CEQA Guidelines Section 15183 provides that when projects are consistent with the development density established by existing zoning, community plan or general plan policies for which an EIR was certified, those projects shall not require additional environmental review, except as might be necessary to examine whether there are project -specific significant effects which are peculiar to the project site. Section 158183 (c) further states that if an impact is not peculiar to the parcel or to the project or has been addressed as a significant effect in the prior EIR or can be substantially mitigated by the imposition of uniformly applied development policies or standard, then an additional EIR need not be prepared. State CEQA Guidelines Section 15183(f) provides that if uniformly applied development policies or standard have been previously adopted with a finding that the policies or standard will substantially mitigate that environmental effect when applied to future projects, effects should not be considered peculiar to the project. The policies or standards need only be applied to the area in which the project is located. In the case of the Proposed Project, the County adopted the policies and mitigation measures within the Santa Clarita Valley Area Plan and its associated 2011 OVOV FEIR. The County adopted the Findings, MMRP, and Statement of Overriding Considerations as part of the 2011 OVOV FEIR, and certified the 2011 OVOV FEIR on November 27, 2012.6 The County made findings that the mitigation measures and policies would substantially reduce the significant effects of the Area Plan. These adopted policies and measures County of Los Angeles Board of Supervisors, A Resolution of The Board of Supervisors of the County Of Los Angeles Relating to the Adoption of General Plan Amendment Number 2009-00006- (5).

Available online at: https:llsantaclarita.gov/capital-improvement-projects/proposed-dockweiler-drive-extension/ Other impacts analyzed in the 2018 Dockweiler FEIR were determined to be less than significant (i.e., hazards and hazardous materials, population and housing; public services; recreation; and utilities) or less than significant with mitigation (i.e., aesthetics; biological resources, cultural resources, geology and soils; hydrology and water quality; and traffic and transportation). As discussed in the detailed analyses below, even though the Project Site extends beyond the Approved Project site boundaries analyzed 2018 Dockweiler FEIR, the mitigation measures identified in the 2018 Dockweiler FEIR, when applied to the Proposed Project, in combination with the 2011 OVOV FEIR mitigation measures and policies, would reduce impacts to a less than significant level for the same issues that are reduced to a less than significant level in the 2018 Dockweiler FEIR.

Impact Sciences, Inc. 17 Placerita Yard Relocation Project 1250.020 Lyons Avenue/Dockweiler Drive Extension Final EIR 2nd Addendum 2. DESCRIPTION OF PROPOSED PROJECT A. PROJECT LOCATION AND BACKGROUND The Project Site is located in the northern area of Los Angeles County (see Figure 1, Regional Location). The limits for the Lyons Avenue/Dockweiler Drive extension are from Railroad Avenue on the west to the future Master's University Master Plan Dockweiler extension to the east. The Los Angeles County Department of Public Works (County) currently owns and uses 22234 Placerita Canyon Road as a maintenance yard. The City of Santa Clarita approved roadway improvements in the vicinity that will require the vacation of the County's maintenance yard located at 22234 Placerita Canyon Road yard, and has proposed 15601 Norland Drive as a new location for the County's maintenance yard. See Figure 2 Project Site. A discussion of the Project Sites' environmental setting is detailed below. 22234 Placerita Canyon Road The County's maintenance yard is located within the Newhall Community in the City (see Figure 1, Regional Location, and Figure 3, Aerial Photograph of Existing Location). As shown in Figure 1, the maintenance yard is within the 2018 Dockweiler FEIR Plan Area and the Santa Clarita Valley Area Plan. Local roadway access to 22234 Placerita Canyon Road is provided through 121h Street and Placerita Canyon Road, and regional roadway access is provided via the Antelope Valley Freeway (California State Route [SR] 14). While 22234 Placerita Canyon Road is mostly paved, it is adjacent to a vacant, unpaved lot (located southeast) and located near the Newhall Creek and tributary (located approximately 312 feet southwest). Additional surrounding uses of the existing location include: school facilities to the north, a single-family residence and vacant lot to the east, and a mini storage area to the south and west. 15601 Norland Drive The maintenance yard would be relocated to 15601 Norland Drive. 15601 Norland Drive is located in the City of Santa Clarita (see Figure 1, Regional Location, and Figure 2, Project Site) approximately 9.5 miles north east of the 22234 Placerita Canyon Road. As shown in Figure 1, 15601 Norland Drive is within the Santa Clarita Valley Area Plan. The surrounding community is within the City of Santa Clarita. The 15601 Norland Drive parcel is approximately 2 acres (87,120 square feet [sf]) located in northern Los Angeles County south of the SR-14 at the terminus of the Oak Springs Canyon Road cul-de-sac. Norland Drive is a service road that bisects the parcel and connects to the existing Oak Springs Canyon Road cul-de-sac. As shown in Figure 4, Aerial Photograph of the Proposed Location, 15601 Norland Drive is currently vacant, with some evidence of previous disturbance. State Route (SR) 14 is directly north of the parcel at an elevation of approximately 15-20 feet higher than the parcel. Sensitive receptors (i.e., single-family residences) are located approximately 400 feet to the north, across SR 14. A deteriorated foundation and an Impact Sciences, Inc. 18 Placerita Yard Relocation Project 1250.020 Lyons AvenuelDockweiler Drive Extension Final EIR 2nd Addendum 2. Description of Currently Proposed Project area of broken concrete/asphalt paving is located off site, on the parcel immediately adjacent to the northeast. Vacant Los Angeles County unincorporated land is located to the east. A major sewer utility easement runs through the center of the site and the Santa Clara River is located immediately to the south. A small pump station operated by Santa Clarita Valley Water is located immediately to the southwest on a separate parcel (see Figure 5, View of Proposed Maintenance Yard Location). A self -storage facility (Sand Canyon RV & Self Storage) is located immediately west, across the cul-de-sac. The topography in the vicinity of the parcel is relatively flat. 2018 Dockweiler FOR The 2018 Dockweiler FEIR evaluated the proposed roadway extension of the Dockweiler Drive eastward to intersect with 13th Street. Specifically, the 2018 Dockweiler FEIR evaluated the extensions impacts to all uses of that may be traversed by the Original Project from Railroad Avenue on the west to the Master's University Campus on the east. The 2018 Dockweiler FEIR also evaluated the proposed upgrade to the existing railroad crossing at the 131h Street and Railroad Avenue intersection. The area analyzed in the 2018 Dockweiler FEIR includes 22234 Placerita Canyon Road. The 2018 Dockweiler FEIR determined that the implementation of the Original Project would result in significant and unavoidable impacts related to localized air emissions and noise related to construction. The 2018 Dockweiler FEIR also determined that impacts related to aesthetics (temporary construction impacts and long-term operational impacts), biological resources (habitat modifications, wildlife, federally protected wetlands, and wildlife movement corridors [construction activities]), cultural resources (archaeological resources, paleontological resources, tribal cultural resources), geology and soils and noise (operational -roadway noise impacts) would be potentially significant but mitigable. As discussed above and in the 2018 Dockweiler FEIR, the Approved Project was identified as the environmentally superior alternative as it would feasibly attain most of the basic objectives of the Original Project. Although it would not reduce or eliminate the Original Project's significant and unavoidable short- term localized construction air quality and construction noise impacts, it would reduce impacts associated with air quality, biological resources, cultural resources, geology/soils, hydrology, construction noise, aesthetics and traffic.

Description of Currently Proposed Project Santa Clarita Valley Area Plan The Santa Clarita Valley Area Plan (Area Plan), also referred to as the One Valley One Vision Plan, serves as a joint planning document between the County and the City, and also serves as a portion of the County's General Plan pursuant to Government Code Sections 65300 et. seq. The Area Plan serves as a foundation for making land use decisions based on goals and policies related to land use, transportation, population growth and distribution, development, open space, resource preservation and utilization, air and water quality, noise impacts, public safety, infrastructure, and other related physical, social, and economic factors. In addition, the Area Plan establishes a clear set of development guidelines for citizens, developers, neighboring jurisdictions and agencies, and provides the community with an opportunity to participate in the planning process. The Plan Area is approximately 485.40 acres in size and encompasses the incorporated boundaries of the City of Santa Clarita, the City's Sphere of Influence,9 and areas within the United States Forest Service (USFS) jurisdiction. One Valley One Vision FEIR The EIR associated with the Santa Clarita Valley Area Plan is the OVOV EIR. The 2011 OVOV FEIR was certified by the County of Los Angeles on November 27, 2012,10 and evaluated the potential impacts related to following environmental topics: • Aesthetics • Agricultural Resources • Air Quality • Biological Resources • Community Services • Cultural Resources • Geology, Soils, Seismicity • Global Warming and Climate Change • Hazards and Hazardous Materials • Hydrology and Water Quality • Land Use • Mineral Resources • Noise • Population and Housing • Public Services • Parks and Recreation • Transportation and Circulation • Utilities and Infrastructure • Water Service The 2011 OVOV FEIR determined that the implementation of the Santa Clarita Valley Area Plan would result in significant and unavoidable impacts related to air quality, agriculture, global climate change, 9 Please note that the City's Sphere of Influence include unincorporated area of Los Angeles County that are in close proximity to the City's boundaries. 10 The 2011 OVOV FEIR was also certified by the City of Santa Clarita on June 14, 2011 Impact Sciences, Inc. 25 Placerita Yard Relocation Project 1250.020 Lyons AvenuelDockweiler Drive Extension Final EIR 2nd Addendum 2. Description of Currently Proposed Project biological resources, noise, and utilities with mitigation implemented. Impacts related to cultural resources, geology, soils, and seismicity, hydrology and water quality, transportation and circulation, public services, utilities, and water services were determined to be potentially significant but mitigable. B. 2018 DOCKWEILER FEIR ASSUMPTIONS The 2018 Dockweiler FEIR assumes that the construction duration for the Approved Project would be the same as the construction duration and use the same construction equipment assumed for the Original Project. The 2018 Dockweiler FEIR generally evaluated the Approved Project's potential construction impacts. Construction activities were envisioned as a multi -phase process. Construction vehicle trips are assumed to occur from heavy-duty construction vehicles and construction worker vehicles Specifically, as detailed in Appendix C to the Dockweiler Draft EIR, construction related analyses included phases associated with grubbing/land clearing, grading/excavation, drainage/utilities/sub-grade, and paving. Key assumptions included: • Construction start year of 2019; • 12 months of construction; • 5 acres for total Project area; • 2 acres of maximum area disturbed per day; and • 223 cubic yards of soil imported/exported per day. C. PROPOSED PROJECT — PLACERITA MAINTENANCE YARD RELOCATION Project Characteristics The Proposed Project would include the relocation of the County's Placerita maintenance yard to a new location on Norland Drive. Consistent with the uses at the Placerita maintenance yard, the following structures/areas would be used at 15601 Norland Drive: • Seven 10' by 40' cargo containers • Two 24' by 40' modular office buildings to accommodate up to 15 staff members • Two (portable) restrooms • 12' by 25' area for heavy equipment vehicle parking (up to 20 vehicles) • Staff parking • Open storage area • Storage Area (approximately 3,400 square feet) The Proposed Project does not include the expansion of any uses from what occurs at the Placerita maintenance yard location. Norland Drive bisects Oak Springs Canyon Road and would need to be Impact Sciences, Inc. 26 Placerita Yard Relocation Project 1250.020 Lyons AvenuelDockweiler Drive Extension Final EIR 2nd Addendum 2. Description of Currently Proposed Project widened approximately three to four feet to accommodate the County's maintenance vehicles. The Proposed Project will also include new water, power, and communications connections to 15601 Norland Drive for operational purposes. The location would be used by County maintenance crews as an area to assemble at the beginning of their shifts before deploying to worksites. Office space (within modular trailers) for administrative and scheduling work, areas to store maintenance vehicles and equipment containers, and employee parking would also be provided. Other than minor repairs, no heavy vehicle maintenance, servicing, or refueling would take place. Therefore, no fuel storage tanks or vehicle maintenance bays that may require the storage and use of petroleum products and solvents will be included. No new permanent structures are proposed. All proposed uses would be accommodated within temporary trailers. All new structures, including restrooms, will be in compliance with the Americans with Disabilities Act (ADA) as per federal and State regulations County Public Works or its designee will undertake any necessary construction activities associated with the Proposed Project such as minor paving and relocation of equipment. Hours of Operation & Staffing The Placerita maintenance yard currently employs 15 staff who generally work from 7:00 AM to 3:00 PM Monday through Thursday, with observances for County holidays. Although the hours of operation are established, the County is ready to respond to urgent requests 24/7. The Proposed Project once relocated would operate in the same hours as the Placerita maintenance yard and is expected to employ the same number of staff. Work hours generally would commence in the early morning (7:00 AM) and would end in the early afternoon (3:00 PM) with the ability to respond to urgent requests at any time. While some staff may remain at the location for the day, most staff would be deployed to work sites throughout the County and would be at the location sporadically throughout the day. Construction Activities & Schedule This analysis assumes a construction schedule of approximately nine months with site cleanup beginning in 2025, and with the Proposed Project fully operational by the end of 2025. This assumption is conservative and yields the maximum daily impacts. The 15601 Norland Drive site is currently vacant, and no demolition will be required. As such, construction activities associated with the Proposed Project would be undertaken in two main steps: (1) site preparation and (2) building construction. This analysis assumes implementation of the Proposed Project would occur within the next year, however, improvements would be based on funding but are expected to occur within one to five years. Nonetheless, these assumptions present a conservative analysis. Impact Sciences, Inc. 27 Placerita Yard Relocation Project 1250.020 Lyons AvenuelDockweiler Drive Extension Final EIR 2nd Addendum 2. Description of Currently Proposed Project Site preparation would occur for approximately three months and this analysis assumes minimal cut/fill operations would balance soil on site and no soil export is required. Building construction would occur for approximately eight months and would include the /placement of the proposed modular buildings, connection of utilities, and paving. Architectural coating and paving are assumed to occur over the final month of the building construction phase. Similar to the assumptions in the 2018 Dockweiler EIR (see above), the Proposed Project involves the same basic phases of construction and conventional construction equipment would be used, such as excavators, backhoes, and both light- and heavy-duty trucks. Equipment and construction staging for the Project will take place onsite. Truck trips are expected to reach the Project Site via Norland Drive. Discretionary Actions and Approvals The development of the Proposed Project requires approval by the County as part of a land purchase from the City. Additional ministerial actions would be required by the County prior to construction. Impact Sciences, Inc. 28 Placerita Yard Relocation Project 1250.020 Lyons AvenuelDockweiler Drive Extension Final EIR 2nd Addendum 3. ENVIRONMENTAL SETTING & IMPACT ANALYSIS The certified Final EIR for the Lyons Avenue/Dockweiler Drive Extension (2018 Dockweiler FEIR) determined the Approved Project (Alternative 2) would be considered the environmentally superior alternative compared to the Original Project. The 2018 Dockweiler FEIR also determined that the Approved Project result in significant and unavoidable impacts in the issue areas identified below. The following discussion also compares impacts of the Proposed Project to the conclusions of the 2018 Dockweiler FEIR. • Air Quality. The 2018 Dockweiler FEIR determined that the Approved Project would result in significant localized air emissions in close proximity to sensitive receptors (residential land uses) within 100 meters of the Project Site on a temporary and intermittent basis during construction. Implementation of Mitigation Measures 4.2-1 through 4.2-4 would require best management practices to minimize construction -related emissions of NOx and CO. However, the 2018 Dockweiler FEIR indicates that construction activities associated with the Approved Project would result in significant and unavoidable impacts with respect to localized air quality The closest sensitive receptor to 15601 Norland Drive is located 400 feet to the north. Additionally, construction activities would be much less intense compared to the Approved Project, as construction activities under the Proposed Project are limited to minimal clearing/ grading and some foundation work. Further, 15601 Norland Drive is much smaller than the Approved Project and therefore would result in a much smaller area of disturbance. Given its distance from sensitive receptors, the Proposed Project would not exceed localized thresholds. Thus, the Proposed Project would result in reduced impacts compared to the Approved Project. • Construction Noise. The 2018 Dockweiler FEIR identified and evaluated the anticipated significant impacts related to construction -noise. The 2018 Dockweiler determined that construction activities associated with the Approved Project (i.e., the use of heavy equipment for ground clearing, site grading, and roadway construction) would generate a noise level of approximately 94.6 dBA, which would exceed acceptable thresholds. Implementation of Mitigation Measures 4.8-1 through 4.8-9 require best management practices to reduce significant temporary increases in noise levels that could exceed established thresholds during construction of the Approved Project to the maximum extent feasible. However, the noise related impacts conservatively are considered to remain a significant adverse impact for the Approved Project. Construction activities associated with the Proposed Project would be minimal compared to the Approved Project. As stated, the closest sensitive receptor to 15601 Norland Drive is located 400 feet to the north, across SR 14, and the Proposed Project would use less construction equipment overall compared to the Approved Project. Therefore, noise and vibration impacts of construction would be Impact Sciences, Inc. 29 Placerita Yard Relocation Project 1250.020 Lyons AvenuelDockweiler Drive Extension Final EIR 2nd Addendum 3. Environmental Setting & Impact Analysis within those evaluated in the 2018 Dockweiler FEIR. Thus, the Project would result in reduced impacts compared to the Approved Project. As documented in the analyses below and summarized in Table 4 below, with the mitigation measures previously adopted with the 2018 Dockweiler FEIR, impacts previously identified as significant would not be worsened, and no new significant or potentially significant impacts to the physical environment would occur as a result of the Proposed Project. The City of Santa Clarita City Council approved the Dockweiler project and made findings regarding the significant and unavoidable impacts, and adopted a Statement of Overriding Considerations.11 Accordingly, the following discussion supports the County's conclusion, pursuant to State CEQA Guidelines Section 15164, that an Addendum is appropriate, and supports a determination by the County that no subsequent EIR is required.

Environmental Setting & Impact Analysis A. AESTHETICS The potential for the Proposed Project to result in new or substantially more adverse significant impacts to aesthetics was evaluated in relation to the 2018 Dockweiler FEIR. (a) Does the Proposed Project require Subsequent or Supplemental CEQA Documentation with respect to impacts on scenic vistas? Yes No New Significant Environmental Effect Caused by a Change in the ❑ Q Project or Circumstances Substantial Increase in the Severity of a Previously Identified ❑ Q Significant Effect Caused by a Change in the Project or Circumstances New or Substantially More Severe Significant Impacts Shown by New ❑ Q Information Ability to Substantially Reduce a Significant Effect Shown by New ❑ Q Information but Declined by Proponent 2018 Dockweiler FEIR Views of the intersection at Lyons Avenue and Railroad Avenue will be altered, as the Approved Project includes street widening and re -profiling the intersection of Lyons Avenue and Railroad Avenue to allow the construction of a new SCRRA/UP railroad at -grade crossing east of Railroad Avenue and the addition of a new bridge crossing Views of the intersection of Lyons Avenue and Railroad Avenue and the hillside on the southeast portion of the Project Site will be altered by grading for the proposed roadway alignment. According to the 2018 Dockweiler FEIR, Lyons Avenue is designated as a Secondary Highway. The 2018 Dockweiler FEIR identified project design features suitable to modifications associated with the landform for a secondary highway. As such, implementation of the Approved Project may result in potentially significant impacts to the Project. Implementation of Mitigation Measure 4.1-2 would reduce impacts to less than significant levels. With incorporation of the project design features and mitigation measures to develop and improve a new roadway extension that is consistent with the City's roadway design standards, the Approved Project would result in a less than significant impact with respect to the loss of an aesthetic natural feature Proposed Project Impacts to scenic vistas under CEQA occur when a project impacts a scenic vista from a publicly available viewing location, such as a roadway. The proposed maintenance yard location, 15601 Norland Drive, sits approximately 20 feet below the SR-14 Freeway. Scenic vistas in the vicinity include the San Gabriel Mountains, located to the southwest. The Proposed Project consists of a limited number of trailers and vehicle parking, none of the proposed uses would be tall enough to impede views from SR 14 of the San Gabriel Mountains from the SR 14. This is due to the parcel's location below the SR 14 roadbed and the Impact Sciences, Inc. 34 Placerita Yard Relocation Project 1250.020 Lyons AvenuelDockweiler Drive Extension Final EIR 2nd Addendum 3. Environmental Setting & Impact Analysis low-rise nature of the proposed buildings and maintenance yard. Due to the limited amount of construction and the temporary nature of construction, as well as the location below the SR 14, construction and operation impacts related to scenic resources would be less than significant. As such, the Proposed Project would not significantly impact on any scenic vistas within the viewshed of the Project Site. As such, there would be no new or greater impacts than those identified in the 2018 Dockweiler FEIR. (b) Does the Proposed Project require Subsequent or Supplemental CEQA Documentation with respect to substantially damaging scenic resources, including, but not limited to, trees, rock outcroppings, and historic buildings within a state scenic highway? Yes No New Significant Environmental Effect Caused by a Change in the ❑ Q Project or Circumstances Substantial Increase in the Severity of a Previously Identified ❑ Q Significant Effect Caused by a Change in the Project or Circumstances New or Substantially More Severe Significant Impacts Shown by New ❑ Q Information Ability to Substantially Reduce a Significant Effect Shown by New ❑ Q Information but Declined by Proponent 2018 Dockweiler FEIR The 2018 Dockweiler FEIR identified no State scenic highways as visible from the Approved Project Site. The 2018 Dockweiler FEIR also concluded that no impacts to scenic resources within a state scenic highway would occur. Proposed Project The closest designated State scenic highway to 15601 Norland Drive is State Route 2 (SR-2), located approximately 18 miles to the east. Due to the distance between this scenic route and the Project Site, as well as the proposed maintenance yard locations overall flat topography, the Proposed Project would result in no impact on scenic highways. As such, the Proposed Project would not result in new or greater impacts in relation to scenic resources within a state scenic highway. Therefore, there would be no new or greater impacts than those identified in the 2018 Dockweiler FEIR. Impact Sciences, Inc. 35 Placerita Yard Relocation Project 1250.020 Lyons AvenuelDockweiler Drive Extension Final EIR 2nd Addendum 3. Environmental Setting & Impact Analysis (c) Does the currently Proposed Project require Subsequent or Supplemental CEQA Documentation with respect to: In non -urbanized areas, substantially degrading the existing visual character or quality of public views of the site and its surroundings? (Public views are those that are experienced from publicly accessible vantage point). In an urbanized area, project conflict with applicable zoning and other regulations governing scenic quality? Yes No New Significant Environmental Effect Caused by a Change in the ❑ .7 Project or Circumstances Substantial Increase in the Severity of a Previously Identified ❑ .7 Significant Effect Caused by a Change in the Project or Circumstances New or Substantially More Severe Significant Impacts Shown by New ❑ .7 Information Ability to Substantially Reduce a Significant Effect Shown by New ❑ Q Information but Declined by Proponent 2018 Dockweiler FEIR The 2018 Dockweiler FEIR determined that the Approved Project result in less than significant impacts with respect to views of existing ridgelines with the application of mitigation measures, which are identified in the 2018 Dockweiler FEIR as a prominent natural feature and a scenic resource. However, visual character would temporarily be adversely impacted due to the visibility of construction materials associated with the Approved Project (i.e., stockpiles of debris and soil, building materials and construction equipment). Implementation of Mitigation Measure 4.1-1 would require the contractor to erect screening materials to effectively block the line of sight of unsightly stockpiles of construction debris and soil from sensitive viewers. As such, impacts were found to be less than significant with mitigation. Proposed Project Impacts to scenic vistas under CEQA occur when a project impacts a scenic vista from a publicly available viewing location, such as a roadway. The San Gabriel Mountains are located southwest from 15601 Norland Drive and are visible from SR-14. As stated above, the Proposed Project consist of a limited number of trailers and vehicle parking, none of the proposed uses would be tall enough to impede views of the San Gabriel Mountains from the SR-14 freeway. Further, the overall visual character of the Norland Drive site is one of disturbed vegetation, as is evidenced both on and around the area. Surrounding uses are similarly disturbed. More urbanized uses are located to the north (approximately 400 feet north of the SR 14 Freeway) and east, across the Norland Drive cul-de-sac. The addition of the new uses would not conflict with surrounding uses but would generally be a continuation of such uses. During construction, most activity would be shielded from view due to the elevation changes and therefore, there would be no need for additional screening such as was required for the Approved Project. Therefore, impacts related to visual Impact Sciences, Inc. 36 Placerita Yard Relocation Project 1250.020 Lyons AvenuelDockweiler Drive Extension Final EIR 2nd Addendum 3. Environmental Setting & Impact Analysis quality would be less than significant. As such, there would be no new or greater impacts than those identified in the 2018 Dockweiler FEIR. (d) Does the Proposed Project require Subsequent or Supplemental CEQA Documentation with respect to creating a new source of substantial light or glare which would adversely affect day or nighttime views in the area? Yes No New Significant Environmental Effect Caused by a Change in the ❑ Q Project or Circumstances Substantial Increase in the Severity of a Previously Identified ❑ Q Significant Effect Caused by a Change in the Project or Circumstances New or Substantially More Severe Significant Impacts Shown by New ❑ Q Information Ability to Substantially Reduce a Significant Effect Shown by New ❑ Q Information but Declined by Proponent 2018 Dockweiler FEIR The 2018 Dockweiler FEIR determined that the Approved Project would introduce nighttime lighting to the vicinity and would be expected to slightly increase ambient lighting in the area. However, compliance with the design standards and requirements established in the Santa Clarita Municipal Code Section 17.51.050 would mitigate lighting impacts to a less than significant level. Proposed Project Construction activities associated with the Proposed Project may introduce new night-time lighting for nighttime construction. However, nighttime light or glare spillover to sensitive uses would not occur due to the existing topography and distance to nearest off site uses (i.e., 400 feet). During operation, maintenance yard would be active during the day due to the type of use and any use during the evenings would be limited as the workers hours are generally 7:00 AM to 3:00 PM. In some cases, the maintenance yard may be utilized at night, but such instances would be rare. As such, the Proposed Project would not create a new source of substantial light or glare. Therefore, there would be no new or greater impacts than those identified in the 2018 Dockweiler FEIR. B. AGRICULTURAL AND FOREST RESOURCES The potential for the Proposed Project to result in new or substantially more adverse significant impacts to agricultural and forest resources was evaluated in relation to the 2018 Dockweiler FEIR and five questions recommended for consideration by the State CEQA Guidelines. Impact Sciences, Inc. 37 Placerita Yard Relocation Project 1250.020 Lyons AvenuelDockweiler Drive Extension Final EIR 2nd Addendum 3. Environmental Setting & Impact Analysis Does the Proposed Project require Subsequent or Supplemental CEQA Documentation with respect to any of the following: (a) Convert Prime Farmland, Unique Farmland, or Farmland of Statewide Importance (Farmland), as shown on the maps prepared pursuant to the Farmland Mapping and Monitoring Program of the California Resources Agency, to non-agricultural use? (b) Conflict with existing zoning for agricultural use, or a Williamson Act contract? (c) Conflict with existing zoning for, or cause rezoning of, forest land (as defined in Public Resources Code section 12220(g)), timberland (as defined by Public Resources Code section 4526), or timberland zoned Timberland Production (as defined by Government Code section 51104(g))? (d) Result in the loss of forest land or conversion of forest land to non -forest use? (e) Involve other changes in the existing environment which, due to their location or nature, could result in conversion of Farmland to non-agricultural use or conversion of forest land to non -forest use? Yes No New Significant Environmental Effect Caused by a Change in the ❑ .7 Project or Circumstances Substantial Increase in the Severity of a Previously Identified ❑ .7 Significant Effect Caused by a Change in the Project or Circumstances New or Substantially More Severe Significant Impacts Shown by New ❑ Q Information Ability to Substantially Reduce a Significant Effect Shown by New ❑ .7 Information but Declined by Proponent 2018 Dockweiler FOR The 2018 Dockweiler FEIR concluded no impacts to agricultural and forestry resources as there are no such resources in the vicinity. The Approved Project is zoned for a mix of commercial and residential use. There is no farmland, timberland or forest land located in the vicinity. The Approved Project location did not contain farmland or agricultural uses, nor are any such lands located within close proximity to the site such that the project could potentially create indirect impacts. Proposed Project There are no agricultural or forestry resources within the Project Site or its vicinity. The Norland Drive site is zoned Open Space (OS) by the County of Los Angeles12 and identified as 'Other Land' by the California Department of Conservation, which is defined as "land that is not included in any other mapping category. Common examples include low density rural developments; brush, timber, wetland, and riparian areas not suitable for livestock grazing; confined livestock, poultry or aquaculture facilities; strip mines, borrow pits; and water bodies 12 County of Los Angeles, "Z-Net Zoning Map."

Vacant and nonagricultural land surrounded on all sides by urban development and greater than 40 acres is mapped as Other Land.-13 As such, the Proposed Project would have no impact on Agricultural and Forestry Resources. Therefore, there would be no new or greater impacts than those identified in the 2018 Dockweiler FEIR. C. AIR QUALITY Air quality impacts of the Proposed Project were evaluated with regard to the 2018 Dockweiler FEIR. The potential for the Proposed Project to result in new or substantially more adverse significant impacts to air quality than analyzed in the 2018 FEIR was evaluated in relation to four questions recommended for consideration by the State CEQA Guidelines. (a) Does the currently Proposed Project require Subsequent or Supplemental CEQA Documentation with respect to conflict with or the potential to obstruct im lementation of the applicable air uali lan? Yes No New Significant Environmental Effect Caused by a Change in the ❑ Q Project or Circumstances Substantial Increase in the Severity of a Previously Identified ❑ Q Significant Effect Caused by a Change in the Project or Circumstances New or Substantially More Severe Significant Impacts Shown by New ❑ Q Information Ability to Substantially Reduce a Significant Effect Shown by New ❑ Q Information but Declined by Proponent 2018 Dockweiler FEIR The 2018 Dockweiler FEIR determined the Approved Project would not exceed the SCAQMD's significance thresholds for regional construction emissions and thus would not increase the frequency or severity of existing air quality violations or cause or contribute to new air quality violations within the Basin. The Approved Project is consistent with the AQMP and would not interfere with attainment of air quality levels identified in the AQMP. The Approved Project would help reduce congestion and vehicles per miles travelled by providing sidewalks and bicycle lanes and by providing direct access from the residential area and the Master's University area to the Jan Heidt Newhall Metrolink Station and Old Town Newhall. The Approved Project encourages alternative modes of transportation other than motor vehicles and would be consistent with the goals and objectives of the AQMP to reduce vehicle emissions throughout the Basin. 13 California Department of Conservation, "Important Farmland Categories." Available online at: htWs://www.conservation.ca.gov/dlrp/fmmp/Pages/Important-Farmland-Categories.asi2x, accessed August 9, 2024. Impact Sciences, Inc. 39 Placerita Yard Relocation Project 1250.020 Lyons Avenue/Dockweiler Drive Extension Final EIR 2nd Addendum 3. Environmental Setting & Impact Analysis Proposed Project The Proposed Project would be within the assumptions made in the 2018 Dockweiler FEIR and would not contribute to a significant impact with respect to the AQMP. The Proposed Project would relocate the existing maintenance yard located at 22234 Placerita Canyon Road to 15601 Norland Drive due to roadway improvements in the vicinity of the current maintenance yard. The Proposed Project would carry out the same operations that are taking place at the Placerita maintenance yard and implement those operations in at 15601 Norland Drive. No new or expanded use would occur. Therefore, Proposed Project impacts related to consistency with the AQMP are less than significant and there would be no new or greater impacts than those identified in the 2018 Dockweiler FEIR. (b) Does the currently Proposed Project require Subsequent or Supplemental CEQA Documentation with respect to the potential to result in a cumulatively considerable net increase of any criteria pollutant for which the project region air basin is non -attainment under an applicable federal or state ambient air quality standard? Yes No New Significant Environmental Effect Caused by a Change in the ❑ Q Project or Circumstances Substantial Increase in the Severity of a Previously Identified ❑ Q Significant Effect Caused by a Change in the Project or Circumstances New or Substantially More Severe Significant Impacts Shown by New ❑ Q Information Ability to Substantially Reduce a Significant Effect Shown by New ❑ Q Information but Declined by Proponent 2018 Dockweiler FEIR Construction As discussed in the 2018 Dockweiler FEIR, construction of the Original Project would occur over an approximate 12-month timeframe and would involve clearing, grading, excavation, trenching, and asphalt paving. Construction would require 4,990 cubic yards (cy) of cut, 2,760 cy of fill, and 2,230 cy of soil export associated with grading and excavation. During construction, on -site stationary sources, heavy-duty construction vehicles, construction worker vehicles, and energy use would generate emissions. Additionally, grading, excavation, and other construction activities on the Project Site would generate fugitive dust emissions. Construction activities and their associated air quality impacts would be short- term in nature and limited only to the period when construction activity is actively taking place on the Project Site. The Project Site under the Original Project would be approximately 5 acres in size and consist of natural land area. For purposes of the analysis, it was assumed that a maximum of approximately 2 acres would be disturbed daily during the development of the Approved Project. Clearing and grubbing of the area was expected to begin in December of 2019 and last through the end of 2020. Like the Original Project, construction of the Approved Project would occur over an approximately 12-month timeframe and would Impact Sciences, Inc. 40 Placerita Yard Relocation Project 1250.020 Lyons AvenuelDockweiler Drive Extension Final EIR 2nd Addendum 3. Environmental Setting & Impact Analysis involve clearing, grading, excavation, trenching, and asphalt paving. As discussed in the 2018 Dockweiler FEIR, the Approved Project's construction emissions would be similar to the emissions generated under the Original Project (see Section 4.2, Air Quality, and Section 6.4, Alternative 2, of the 2018 Dockweiler FEIR) but slightly reduced as the Approved Project would involve less mass grading. The increased emissions associated with the Arch Street to 13th Street improvements would be offset by the avoidance of grading associated with the Dockweiler to Lyons connection. As the Original Project emissions would be below South Coast Air Quality Managements District's (SCAQMD's) significance thresholds for all criteria pollutants, the Approved Project's regional construction air quality emissions were also found to be less than significant. Operation A CO hotspot analysis was conducted for the Original Project, which includes the roadway extension of Lyons Avenue to Dockweiler Drive and the closure of the railroad crossing and vehicular access at the intersection of 13th and Railroad Avenue. As discussed in Section 4.2 Air Quality, of the EIR, modeling of future CO concentrations from the intersections in the study area was based on projected traffic volumes from the intersections contained in the Original Project Traffic Study. Interim year 2019 with -project conditions CO concentrations were calculated for peak hour traffic volumes for those intersections that are anticipated to operate at LOS D or worse, based on the traffic analysis for the Project (see Section 4.9, Transportation and Traffic of the EIR). Background (existing) ambient CO concentrations were also factored into the analysis. The results of these CO Hotspot concentration calculations are presented in Section 4.2 Air Quality, Table 4.2-11, Existing Conditions Plus Project (2019) Carbon Monoxide Concentrations, of the EIR. As shown in Table 4.2-11, the screening calculations predict that, under worst case conditions, future carbon monoxide (CO) concentrations at each intersection would not exceed the state 1-hour and 8-hour standards with or without the development of the Original Project. Although the Approved Project would not directly generate any new vehicle trips, it would result in changes to the traffic circulation in the vicinity and would alter the average daily traffic volumes and peak hour traffic volumes at local intersections. As the Approved Project is within the same envelope as the Original Project, it was found that, under worst -case conditions, future CO concentrations at each intersection would not exceed the state 1-hour and 8-hour standards with or without the development of the Project. Therefore, no significant project -related impact would occur relative to future carbon monoxide concentrations of the Approved Project. The Approved Project was found to have a less than significant impact with respect to this criterion. Impact Sciences, Inc. 41 Placerita Yard Relocation Project 1250.020 Lyons AvenuelDockweiler Drive Extension Final EIR 2nd Addendum 3. Environmental Setting & Impact Analysis Proposed Project Construction Similar to the assumptions in the 2018 Dockweiler FEIR (see above), the Proposed Project involves the same basic phases of construction and conventional construction equipment would be used, such as excavators, backhoes, and both light- and heavy-duty trucks. The Proposed Project generally requires less daily and total construction activity and associated equipment. As such, the daily construction emissions from the establishment of the new maintenance yard at Norland Drive would be less than those disclosed for the Approved Project and there would be no new or greater impacts than those identified in the 2018 Dockweiler FEIR. Operation The Proposed Project would not increase the number of trips compared to existing conditions at the Placerita maintenance yard. Given that the operations from the Placerita maintenance yard would simply be relocated to a new location, it is reasonable to assume that the operational emissions generated would be comparable to the Placerita maintenance yard. Therefore, no mitigation would be required and there would be no new or greater impacts than those identified in the 2018 Dockweiler FEIR. W Does the currently Proposed Project require Subsequent or Supplemental CEQA Documentation with respect to the potential to expose sensitive receptors to substantial pollutant concentrations? Yes No New Significant Environmental Effect Caused by a Change in the ❑ Q Project or Circumstances Substantial Increase in the Severity of a Previously Identified ❑ Q Significant Effect Caused by a Change in the Project or Circumstances New or Substantially More Severe Significant Impacts Shown by New ❑ Q Information Ability to Substantially Reduce a Significant Effect Shown by New ❑ Q Information but Declined by Proponent 2018 Dockweiler FEIR Construction The Approved Project would result in significant localized air emissions in close proximity to residential land uses within 100 meters (328 feet) of the Approved Project Site on a temporary and intermittent basis during construction. Localized NOx and CO emissions would be below the significance thresholds at all sensitive receptor locations. However, localized thresholds would be exceeded for PM10 and PM2.5 emissions at two locations: (1) the single-family residential land uses located immediately north of the Approved Project Site (within a proximity of 100 meters) and (2) the residential land uses within 100 meters Impact Sciences, Inc. 42 Placerita Yard Relocation Project 1250.020 Lyons AvenuelDockweiler Drive Extension Final EIR 2nd Addendum 3. Environmental Setting & Impact Analysis south of the Approved Project Site in the vicinity of Market Street and Race Street (see Section 4.2 Air Quality, Table 4.2-10, of the 2018 Dockweiler FEIR). Localized emissions would be below the stated thresholds for any land use located further than 100 meters from the Approved Project Site. Therefore, notwithstanding implementation of Mitigation Measures 4.2-1 through 4.2-4, which require best management practices to minimize construction -related emissions, localized air quality impacts resulting from construction activities would be considered significant and unavoidable. Operation Localized operational emissions were not discussed in the 2018 Dockweiler FEIR, however operational emissions on a regional level were determined to be less than significant. Proposed Project Construction Similar to the assumptions in the 2018 Dockweiler FEIR, the Proposed Project involves the same basic phases of construction and conventional construction equipment would be used, such as excavators, backhoes, and both light- and heavy-duty trucks. However, the Proposed Project generally requires less daily and total construction activity and associated equipment; the Proposed Project seeks to relocate the Placerita maintenance yard to a new location as opposed to the parameters of the Approved Project, which includes street and railroad improvements over a larger acreage. Only minor construction trips would occur as a result of moving and placement of trailer, grading and minor clearing. The emissions associated with construction would be well within the parameters of the Approved Project which requires earthmoving and paving. As such, the localized daily construction emissions from the establishment of the new maintenance yard would be less than those disclosed for the Approved Project. Furthermore, as stated above, the 2018 Dockweiler FEIR determined that localized emissions would be below the thresholds for any land use located more than 100 meters (328 feet) away from the Approved Project Site. The closest sensitive receptors to 15601 Norland Drive are more than 400 feet to the north. Given the distance to the closest air quality sensitive receptor exceeds 100 meters, the Proposed Project would not exceed localized thresholds As such, localized air quality construction impacts under the Proposed Project would be less than significant without mitigation, and there would be no new or greater impacts than those identified in the 2018 Dockweiler FEIR. Operation Implementation of the Proposed Project would result in the relocation of the current maintenance yard located at 22234 Placerita Canyon Road to 15601 Norland Drive.

Environmental Setting & Impact Analysis proposed compared to the existing operations. Consistent with the 2018 Dockweiler FEIR, impacts on local receptors from operation of the Proposed Project would be less than significant and there would be no new or greater impacts than those identified in the 2018 Dockweiler FEIR. (d) Does the Proposed Project require Subsequent or Supplemental CEQA Documentation with respect to creating objectionable odors affecting a substantial number of peo le? Yes No New Significant Environmental Effect Caused by a Change in the ❑ Q Project or Circumstances Substantial Increase in the Severity of a Previously Identified ❑ Q Significant Effect Caused by a Change in the Project or Circumstances New or Substantially More Severe Significant Impacts Shown by New ❑ Q Information Ability to Substantially Reduce a Significant Effect Shown by New ❑ Q Information but Declined by Proponent 2018 Dockweiler FEIR The 2018 FEIR acknowledges that a significant impact may occur if objectionable odors occur that would adversely impact sensitive receptors but does not make a determination if the Approved Project would result in objectionable odors. Despite this, it is reasonable to assume that construction associated with the Approved Project would be required to comply with California Code of Regulations (CCR), Title 13, sections 2449(d)(3) and 2485, which minimizes the idling time of construction equipment. With respect to operation, uses that are typically considered by the SCAQMD to be a source of odor complaints (agriculture uses, food processing and chemical plants, composting refineries, landfills and other uses) are not proposed and therefore impacts are deemed to be less than significant. Proposed Project The Proposed Project would not result in unusual or objectionable odors. Clearing and grading of the site would involve equipment that can produce discernible odors typical of most construction sites. In addition, paving and the application of paints and coatings can also be a source of discernable odors. The construction of the Proposed Project would be subject to regulations established in CCR Title 13, sections 2449(d)(3) and 2485 as well as SCAQMD rules and regulations, such as Rule 1113. Any temporary odors would be typical in an urban environment and would be short-term in nature. Therefore, like the Approved Project, they would not be considered a significant environmental impact and there would be no new or greater impacts than those identified in the 2018 Dockweiler FEIR.

BIOLOGICAL RESOURCES The potential for the Proposed Project to result in new or substantially more adverse significant impacts to biological resources than analyzed in the 2018 Dockweiler FEIR was evaluated in relation to the six questions recommended for consideration by the State CEQA Guidelines. Does the Proposed Project require Subsequent or Supplemental CEQA Documentation with respect to the following: a) Have a substantial adverse effect, either directly or through habitat modifications, on any species identified as a candidate, sensitive, or special status species in local or regional plans, policies, or regulations, or by the California Department of Fish and Wildlife or U.S. Fish and Wildlife Service (USFWS)? Yes No New Significant Environmental Effect Caused by a Change in the ❑ .7 Project or Circumstances Substantial Increase in the Severity of a Previously Identified ❑ Q Significant Effect Caused by a Change in the Project or Circumstances New or Substantially More Severe Significant Impacts Shown by ❑ .7 New Information Ability to Substantially Reduce a Significant Effect Shown by New ❑ Q Information but Declined by Proponent 2018 Dockweiler FEIR The 2018 Dockweiler FEIR involves a roadway expansion as described above. As part of the Approved Project, the 2018 Dockweiler FEIR identified the potential for project -related activities associated with site preparation and construction to result in the direct loss of individuals of one special status wildlife species (the silvery legless lizard) and of active nests or the abandonment of active nests by adult birds should grading occur during nesting season. The loss of a California species of special concern and active bird nests was determined to be significant without mitigation. The 2018 Dockweiler EIR also identified the loss of 2.32 acres of habitat and determined that due to its proximity to adjacent developed areas, combined with its small size (2.32 acres), the lack of sensitive plant communities, the lack of structure for wildlife, and high percentage of invasive and non-native plant species generally associated with disturbed areas, impacts associated with the loss of 2.32 acres of vegetation present on -site was considered less than significant. Implementation of Mitigation Measures 4.3-1 through 4.3-2, 4.3-4, 4.3-6 and 4.3-7 would reduce impacts to sensitive species to a less than significant level. These measures require preconstruction surveys (MM 4.3-1), compliance with the MBTA (MM4.3-2), and use of a qualified biologist to monitor construction (MM 4.3-4) Impact Sciences, Inc. 45 Placerita Yard Relocation Project 1250.020 Lyons AvenuelDockweiler Drive Extension Final EIR 2nd Addendum 3. Environmental Setting & Impact Analysis Proposed Project As described in the Project Description, 15601 Norland Drive is not within the area analyzed by the 2018 Dockweiler FEIR and is primarily comprised of disturbed habitat and sparse vegetation. As such, a biological resources assessment was prepared to assess the potential for special status species or habitat to occur. The assessment is provided in Appendix A of this Addendum. The findings indicate there is no suitable habitat for special status plant species and no special status plants were observed during field observations. However, three special status wildlife taxa were determined to have moderate potential for occurrence in the Study Area:14 1. California Gnatcatcher (Polioptila californica californica) prefer to inhabit Sagescrub communities with nesting habitat in the form of scrub species taller than three feet in height. Suitable habitat is found within the Project site as Sage (Salvia ssp.) were detected but at low densities. No individuals were detected during the survey. 2. Arroyo Toad (Anaxyrus californicus) require slow moving, narrow, and shallow aquatic habitat with nearby upland areas for burrowing. The Santa Clara River provides suitable habitat for this species especially during rain events. 3. Western Spadefoot (Spea hammondii) inhabit areas where they can burrow to hide against predators and have water sources for breeding. The western spadefoot becomes active for a short period between October and March. Four special status wildlife taxa were determined to have low potential for occurrence in the Study Area: 1. Least Bell's vireo (Vireo belhi pusillus) occur in riparian areas with dense vegetation cover and trees for nesting. The Project Site is unlikely to support this species due to the lack of riparian habitat present. 2. Southwestern pond turtle (Actinemys pallida) occupy riparian habitat with slow moving waters with dense vegetation for foraging and hiding from predators. There is low potential for the Project Site to support this species due to the long distance an individual would have to travel from the perennial stream. 3. Monarch Butterfly (Danaus Plexippus) utilize milkweed (Asclepias ssp.) as a host plant. The site survey was conducted in May 2024 which is outside of the appropriate time to survey for the plant. 14 The Study Area for the Biological Resources Assessment is the parcel located at 15601 Norland Drive and a 500- foot buffer. Impact Sciences, Inc. 46 Placerita Yard Relocation Project 1250.020 Lyons AvenuelDockweiler Drive Extension Final EIR 2nd Addendum 3. Environmental Setting & Impact Analysis 4. CrotcWs Bumble Bee (Bombus crotchii) inhabit largely undisturbed habitat where there is sufficient flower production by plants and can utilize burrows for nesting sites. Outside of nesting season the species will burrow underground to hide from predators and rest. The study area is unlikely to host this species as the density of flowering species is low. The Biological Resources Assessment determined no impacts to special status species or habitat are expected to result from implementation of the Proposed Project. The Norland Drive location has already been disturbed and provides little to no habitat for wildlife with the exception of shrub nesting birds along Norland Drive. Raptors may utilize the open area for hunting lizards and small rodents, but no trees are tall enough to support nesting raptors. Vegetation along Norland Drive may be too dense for burrowing and ground nesting species, but this vegetation does provide refuge for small mammals and reptiles. No burrows were found on the vacant lot of the proposed maintenance yard but soils along the eastern half of the lot may be suitable for burrowing species.15 However, because there is low potential for four species and moderate potential for three species to occur, similar to the Approved Project, preconstruction surveys are necessary. The Santa Clarita Valley Area Plan, as described above, covers a broad area of both County and City jurisdiction, including the proposed maintenance yard site. Potentially significant impacts associated with the Santa Clarita Valley Area Plan include those relating to special -status species and sensitive communities; specifically, previously adopted OVOV mitigation measures MM 3.7-1 through 3.7-2 reduce potential impacts related to special status species. MM 3.7-1 requires preparation of biological site survey reports prepared by a qualified biological consultant for proposed projects. MM 3.7-2 addresses direct mortality of special -status species through construction activities. As discussed above, the Dockweiler EIR also identified impacts to special status species that would require mitigation. Dockweiler EIR Mitigation Measure MM 4.3-4 includes guidelines related to construction when biological resources are present. As discussed above, mitigation measures included in the 2011 OVOV FEIR and 2018 Dockweiler FEIR, are required for the Proposed Project. With implementation of required mitigation, impacts associated with habitat modifications and any species identified as a candidate, sensitive, or special status would be less than significant. Therefore, there would be no new or greater impacts than those identified in the 2018 Dockweiler FEIR. 15 Bargas Environmental, Placerita Maintenance Yard Project Biological Resources Assessment, May 2024. Impact Sciences, Inc. 47 Placerita Yard Relocation Project 1250.020 Lyons AvenuelDockweiler Drive Extension Final EIR 2nd Addendum 3. Environmental Setting & Impact Analysis Does the Proposed Project require Subsequent or Supplemental CEQA Documentation with respect to the following: b) Have a substantial adverse effect on any riparian habitat or other sensitive natural community identified in local or regional plans, policies, regulations or by the California Department of Fish and Wildlife or U.S. Fish and Wildlife Service? Yes No New Significant Environmental Effect Caused by a Change in the ❑ .7 Project or Circumstances Substantial Increase in the Severity of a Previously Identified ❑ Q Significant Effect Caused by a Change in the Project or Circumstances New or Substantially More Severe Significant Impacts Shown by ❑ .7 New Information Ability to Substantially Reduce a Significant Effect Shown by New ❑ Q Information but Declined by Proponent 2018 Dockweiler FOR The 2018 Dockweiler EIR did not identify any riparian habitat. Two jurisdictional features were determined to occur within the Project Site and area: Newhall Creek and a small ephemeral drainage that is a tributary to Newhall Creek. Both fall under the jurisdiction of the CDFW. Although these jurisdictional features do not support riparian vegetation or sensitive wetland resources, Mitigation Measure 4.3-3 was identified to reduce impacts to jurisdictional waters to less than significant. Proposed Project The Project results from the approved Dockweiler project. Although the Norland Drive location is not within the Dockweiler EIR project area, it is located within the Santa Clarita Valley Area Plan area. The Norland drive location is vacant with disturbed vegetation. As described under impact (a) above, there is low potential for riparian species to occur on the site due to the lack of riparian habitat.16 Nonetheless, the Proposed Project would comply with previously adopted Mitigation Measures MM 3.7-1 through 3.7-2 reduce potential impacts related to special status species. MM 3.7-1 requires preparation of biological site survey reports by a qualified biological consultant for proposed projects. MM 3.7-2 addresses direct mortality of special -status species through construction activities. Dockweiler Mitigation Measure MM 4.3- 4 includes guidelines related to construction when biological resources are present. Therefore, implementation of the Project would not have a substantial adverse effect on any riparian or sensitive natural communities identified by regional plans, policies, regulations, or California Department of Fish and Game or U.S. Fish and Wildlife Service. There would be no new or greater impacts than those identified in the certified 2018 Dockweiler FEIR. 16 Bargas Environmental, Placerita Maintenance Yard Project Biological Resources Assessment, May 2024. Impact Sciences, Inc. 48 Placerita Yard Relocation Project 1250.020 Lyons AvenuelDockweiler Drive Extension Final EIR 2nd Addendum 3. Environmental Setting & Impact Analysis Does the Proposed Project require Subsequent or Supplemental CEQA Documentation with respect to the following: c) Have a substantial adverse effect on federally protected wetlands as defined by Section 404 of the Clean Water Act (including, but not limited to, marsh, vernal pool, coastal, etc.) through direct removal, filling, hydrological interruption, or other means? Yes No New Significant Environmental Effect Caused by a Change in the ❑ .7 Project or Circumstances Substantial Increase in the Severity of a Previously Identified ❑ Q Significant Effect Caused by a Change in the Project or Circumstances New or Substantially More Severe Significant Impacts Shown by ❑ .7 New Information Ability to Substantially Reduce a Significant Effect Shown by New ❑ Q Information but Declined by Proponent 2018 Dockweiler FOR As part of the Approved Project, the 2018 Dockweiler FEIR identified the potential for both temporary and permanent impacts to areas of the Newhall Creek and its associated tributary and are classified as "riverine and relatively permanent water, with continuous flow at least seasonally" and as such are under CDFW jurisdiction. Without consultation and a formal agreement with CDFW, such impacts would be in violation of the Fish and Game Code and considered a significant impact. Without mitigation, the project would result in potentially significant impacts to CDFW jurisdictional resources (i.e., Newhall Creek and its associated tributary). Mitigation Measure 4.3-3 was determined to reduce impacts to jurisdictional resources to a less than significant level. Proposed Project According to the BRA (see Appendix A) there are no aquatic, wetland, or riparian habitat, or other sensitive natural communities on the Norland Drive location and no signatures of wetlands were present on the site during the site visit.17 The 2018 Dockweiler FEIR identifies mitigation measure MM 4.3-3 which relates to development in Newhall Creek, a jurisdictional water. The OVOV FEIR determined that protection of sensitive wetland and woodland habitats, state- and federally listed species habitats, and habitats within SEAs and along the Santa Clara River and its tributaries (Policies CO 3.2.1, 3.2.2, 3.2.3, and 3.2.4, 3.3.1) would help to protect wetland habitats within the Santa Clarita Valley Area Plan Area. The Proposed Project would be in compliance with the above policies. Therefore, impacts related to adverse effects on federally protected wetlands as defined by Section 404 of the Clean Water Act through direct removal, filling, hydrological interruption, or other means were determined to be less than significant. The Proposed 17 Bargas Environmental, Placerita Maintenance Yard Project Biological Resources Assessment, May 2024. See Appendix A. Impact Sciences, Inc. 49 Placerita Yard Relocation Project 1250.020 Lyons AvenuelDockweiler Drive Extension Final EIR 2nd Addendum 3. Environmental Setting & Impact Analysis Project would comply with OVOV policies and applicable Dockweiler mitigation measures. As such, implementation of the Proposed Project would not cause a significant impact to potentially environmentally sensitive jurisdictional wetlands. Therefore, there would be no new or greater impacts than those identified in the certified 2018 Dockweiler FEIR. Does the Proposed Project require Subsequent or Supplemental CEQA Documentation with respect to the following: (d) Interfere substantially with the movement of any native resident or migratory fish or wildlife species or with established native resident or migratory wildlife corridors, or impede the use of native wildlife nursery sites? Yes No New Significant Environmental Effect Caused by a Change in the ❑ .7 Project or Circumstances Substantial Increase in the Severity of a Previously Identified ❑ Q Significant Effect Caused by a Change in the Project or Circumstances New or Substantially More Severe Significant Impacts Shown by ❑ Q New Information Ability to Substantially Reduce a Significant Effect Shown by New ❑ Q Information but Declined by Proponent 2018 Dockweiler FEIR The 2018 Dockweiler FEIR determined direct loss of active nests or the abandonment of active nests by adult birds should grading occur during nesting season would be a significant impact. The loss of California species active bird nests was determined to be significant without mitigation. Implementation of Mitigation Measure 4.3-2 would reduce impacts by requiring the Project to comply with all measures outlined in the Migratory Bird Treaty Act. As such, impacts to nesting birds would be less than significant. The 2018 Dockweiler FEIR also determined that the Approved Project Site provides passage through developed areas between the Santa Clarita River and the Angeles National Forest to the southeast and is considered a part of a wildlife movement or migration corridor. To limit impacts to wildlife movement, mitigation was required. With mitigation, the Approved Project would not result in any barrier to wildlife movement and would serve to protect Newhall Creek as a functioning wildlife movement corridor. Therefore, the 2018 Dockweiler FEIR determined the Approved Project would not result in significant impacts to wildlife movement. Proposed Project As previously discussed, the Norland Drive site is relatively flat, but the Santa Clara River and Santa Clarita City discharge channel are located immediately outside the site boundary. Impact Sciences, Inc. 50 Placerita Yard Relocation Project 1250.020 Lyons AvenuelDockweiler Drive Extension Final EIR 2nd Addendum 3. Environmental Setting & Impact Analysis Implementation of the Proposed Project would not have a direct impact on the movement of wildlife. Construction noise may temporarily deter movement from the adjacent Santa Clara River, but construction would be limited to daylight hours and wildlife would not be disturbed during the times they typically travel (dawn, dusk, and night). Few trees are located within the proposed maintenance yard site, which limits the opportunities for birds to nest. However, some shrub or ground nesting species might find suitable nesting locations at the far west end of Norland Drive where the vegetation is dominated by Common Sagebrush (Artemesia tridentata). All nesting birds and their eggs are protected by the Migratory Bird Treaty Act. Compliance with the MBTA is required under Dockweiler Mitigation Measure MM 4.3- 2 and would reduce any potential impacts to less than significant. Therefore, implementation of the Proposed Project would not have the potential to interfere with the movement of wildlife or impact wildlife nursery sites. Therefore, there would be no new or greater impacts than those identified in the 2018 Dockweiler FEIR. Does the Proposed Project require Subsequent or Supplemental CEQA Documentation with respect to the following: (e) Does the currently Proposed Project require Subsequent or Supplemental CEQA Documentation with respect to conflict with any local policies or ordinances protecting biological resources, such as tree reservation policy or ordinance? Yes No New Significant Environmental Effect Caused by a Change in the ❑ Q Project or Circumstances Substantial Increase in the Severity of a Previously Identified ❑ Q Significant Effect Caused by a Change in the Project or Circumstances New or Substantially More Severe Significant Impacts Shown by ❑ Q New Information Ability to Substantially Reduce a Significant Effect Shown by New ❑ Q Information but Declined by Proponent 2018 Dockweiler FEIR The 2018 Dockweiler FEIR determined the Approved Project would adhere to all local policies and ordinances protecting biological resources, such as tree preservation policy or ordinance. Therefore, impacts were found to be less than significant. Proposed Project The Norland Drive site is vacant within a relatively undeveloped area. Land uses in the surrounding area include Public Facilities (SR 14), Light Industrial (a public storage facility), Open Space, and the Santa Clara River. There are no protected tree species and no trees are anticipated to be removed as part of the Proposed Project. As such, impacts related to protected trees would be less than significant. Therefore, there would be no new or greater impacts than those identified in the certified 2018 Dockweiler FEIR. Impact Sciences, Inc. 51 Placerita Yard Relocation Project 1250.020 Lyons AvenuelDockweiler Drive Extension Final EIR 2nd Addendum 3. Environmental Setting & Impact Analysis Does the Proposed Project require Subsequent or Supplemental CEQA Documentation with respect to the following: W Does the currently Proposed Project require Subsequent or Supplemental CEQA Documentation with respect to an adopted Habitat Conservation Plan, Natural Community Conservation Plan, or other approved local, regional, or state habitat conservationplan? Yes No New Significant Environmental Effect Caused by a Change in the ❑ .7 Project or Circumstances Substantial Increase in the Severity of a Previously Identified ❑ .7 Significant Effect Caused by a Change in the Project or Circumstances New or Substantially More Severe Significant Impacts Shown by ❑ .7 New Information Ability to Substantially Reduce a Significant Effect Shown by New ❑ Q Information but Declined by Proponent 2018 Dockweiler FOR The 2018 Dockweiler FEIR determined the Approved Project would adhere to all provisions of an adopted Habitat Conservation plan, Natural Community Conservation plan, or other approved local, regional, or State Habitat Conservation plan. Because the Approved Project is not within the purview of an adopted Habitat Conservation Plan, Natural Community Conservation plan, or other approved local, regional, or State Habitat Conservation Plan, impacts were determined to be less than significant. Proposed Project The County created the Significant Ecological Areas (SEA) Program to officially identify areas within Los Angeles County that contain irreplaceable biological resources. The SEA Program seeks to conserve genetic and physical diversity within the County by designating biological resource areas that are capable of sustaining themselves into the future. The Norland Drive site is within an SEA.18 SEAs are not "preserves," and limited development is allowed within these designated areas. However, in order to conserve important biological resources, land -intensive development in SEAs within County areas requires approval of a Conditional Use Permit and an additional level of review by the SEA Technical Advisory Committee. However, these conditions are not applicable to the Proposed Project as it is both an allowed use within the zone and would not create a land intensive use. Rather, any improvements would be minor in the form of temporary modular buildings and minor clearing. Further, the Proposed Project is incorporating all applicable mitigation measures from both the 2018 Dockweiler FEIR and the 2011 OVOV FEIR. 18 Los Angeles County, "Significant Ecological Areas."

Impact Sciences, Inc. 52 Placerita Yard Relocation Project 1250.020 Lyons Avenue/Dockweiler Drive Extension Final EIR 2nd Addendum 3. Environmental Setting & Impact Analysis In addition, the Proposed Project is required to be designed to be compatible with biological resources, maintain watercourses and water bodies in a natural state, maintain wildlife corridors, preserve adequate buffer areas or barriers between development and natural resources, and ensure that roads and utilities are designed to mitigate impacts to biological resources. Adherence to the mitigation measures included in the 2011 OVOV FEIR and 2018 Dockweiler FEIR would accomplish these requirements. As such, implementation of the Project would not conflict with any conservation plans. Therefore, there would be no new or greater impacts than those identified in the certified 2018 Dockweiler FEIR. E. CULTURAL RESOURCES The potential for the Proposed Project to result in new or substantially more adverse significant impacts to cultural resources was evaluated in relation to the 2018 Dockweiler FEIR and three questions recommended for consideration by the State CEQA Guidelines. (a) Does the Proposed Project require Subsequent or Supplemental CEQA Documentation with respect to causing a substantial adverse change in the significance of a historical resource as defined in §15064.5? Yes No New Significant Environmental Effect Caused by a Change in the ❑ Q Project or Circumstances Substantial Increase in the Severity of a Previously Identified ❑ Q Significant Effect Caused by a Change in the Project or Circumstances New or Substantially More Severe Significant Impacts Shown by New ❑ Q Information Ability to Substantially Reduce a Significant Effect Shown by New ❑ Q Information but Declined by Proponent 2018 Dockweiler FEIR Cultural and Historic Resources No cultural or historic habitable structures are located on -site, and as such, the Approved Project would not have the potential to adversely impact any historic or cultural resources. Proposed Project The Norland Drive site is currently undeveloped with no structures and does not contain any known historic resources. Therefore, no impacts would occur, and there would be no new or greater impacts than those identified in the certified 2018 Dockweiler FEIR. Impact Sciences, Inc. 53 Placerita Yard Relocation Project 1250.020 Lyons AvenuelDockweiler Drive Extension Final EIR 2nd Addendum 3. Environmental Setting & Impact Analysis (b) Cause a substantial adverse change in the significance of an archaeological resource pursuant to §15064.5? (c) Disturb any human remains, including those interred outside of formal cemeteries? Yes No New Significant Environmental Effect Caused by a Change in the ❑ Q Project or Circumstances Substantial Increase in the Severity of a Previously Identified ❑ Q Significant Effect Caused by a Change in the Project or Circumstances New or Substantially More Severe Significant Impacts Shown by New ❑ Q Information Ability to Substantially Reduce a Significant Effect Shown by New ❑ Q Information but Declined by Proponent 2018 Dockweiler FEIR Archeological Resources and Human Remains No known archeological sites are identified within the Project Site for the Approved Project. However, construction -related earthwork activities may result in the accidental discovery of prehistoric or historic archaeological resources or Native American burial sites. Implementation of Mitigation Measure 4.4-1, which would ensure the preservation, conservation, or relocation in the event any resources are discovered during construction -related earthwork activities, would reduce impacts to a less than significant level. Proposed Project The Norland Drive site is currently undeveloped and does not contain any structures. Although limited, like the 2018 Dockweiler FEIR, construction -related earthwork during development of the Proposed Project has potential to encounter prehistoric or historic archeological resources and or Native American burial sites. Consistent with the 2018 Dockweiler FEIR, implementation of Mitigation Measure 4.4-1, would be necessary to ensure that impacts to these cultural and tribal resources remain less than significant. Therefore, there would be no new or greater impacts than those identified in the certified 2018 Dockweiler FEIR. F. ENERGY As part of the 2018 State CEQA Guidelines updates, new Energy checklist questions were added that require lead agencies to determine a project's demand on electricity, natural gas, and transportation energy. Subsequent to the adoption of the 2018 Dockweiler FEIR, the State CEQA Guidelines have been amended to require lead agencies to determine a project's potential impacts to energy conservation and resources. The potential for the Proposed Project to result in new or substantially more adverse significant impacts related to Energy were evaluated in relation to two questions recommended for consideration by the State CEQA Guidelines. Impact Sciences, Inc. 54 Placerita Yard Relocation Project 1250.020 Lyons AvenuelDockweiler Drive Extension Final EIR 2nd Addendum 3. Environmental Setting & Impact Analysis Does the Proposed Project require Subsequent or Supplemental CEQA Documentation with respect to the following: (a) Result in potentially significant environmental impact due to wasteful, inefficient, or unnecessary consumption of energy resources, during project construction or operation? (b) Conflict with or obstruct a state or local plan for renewable enerKT or energy efficiency? Yes No New Significant Environmental Effect Caused by a Change in the ❑ .7 Project or Circumstances Substantial Increase in the Severity of a Previously Identified ❑ .7 Significant Effect Caused by a Change in the Project or Circumstances New or Substantially More Severe Significant Impacts Shown by New ❑ Q Information Ability to Substantially Reduce a Significant Effect Shown by New ❑ Q Information but Declined by Proponent Proposed Project The California Green Building Standards Code (CALGreen Code) establishes mandatory measures for new non-residential buildings, which includes requirements for energy efficiency, water conservation, material conservation, planning and design, and overall environmental quality. Although minimal construction is proposed, any and all construction would comply with or exceed the applicable provisions of the Title 24 Building Standards Code and the California Green Building Standards in effect at the time of building permit issuance. Transportation fuels are utilized for necessary on -site activities and off -site transportation associated with facility employees traveling to and from the site. Operation of the Proposed Project would utilize energy in the same capacity as the Placerita maintenance yard. The amount of energy used would not represent a substantial fraction of the available energy supply in terms of equipment and transportation fuels. As a result, impacts related to energy conservation and resources would be less than significant and there would be no new or greater impacts than those identified in the 2018 Dockweiler FEIR. G. GEOLOGY AND SOILS Impacts with respect to geology and soils of the Proposed Project were evaluated with regard to the 2018 Dockweiler FEIR and adopted mitigation measures. The potential for the Proposed Project to result in new or substantially more adverse significant impacts to geology and soils was evaluated in relation to eight questions recommended for consideration by the State CEQA Guidelines. Does the currently Proposed Project require Subsequent or Supplemental CEQA Documentation with respect to the following: (a) Expose people or structures to potential substantial adverse effects, including the risk of loss, injury, or death involving: i) Rupture of a known earthquake fault, as delineated on the most recent Alquist-Priolo Earthquake Fault Zoning Map issued by the State Geologist for the area or based on other substantial evidence of a known fault? Refer to Division of Mines and Geology Special Publication 42. ii) Strong seismic Impact Sciences, Inc. 55 Placerita Yard Relocation Project 1250.020 Lyons AvenuelDockweiler Drive Extension Final EIR 2nd Addendum 3. Environmental Setting & Impact Analysis iii) Seismic -related ground failure, including liquefaction as delineated on the most recent Seismic Hazards Zones Map issued by the State Geologist for the area or based on other substantial evidence of known areas of liquefaction? iv) Landslides as delineated on the most recent Seismic Hazards Zones Map issued by the State Geologist for the area or based on other substantial evidence of known areas of landslides? Yes No New Significant Environmental Effect Caused by a Change in the ❑ Q Project or Circumstances Substantial Increase in the Severity of a Previously Identified ❑ Q Significant Effect Caused by a Change in the Project or Circumstances New or Substantially More Severe Significant Impacts Shown by ❑ Q New Information Ability to Substantially Reduce a Significant Effect Shown by New ❑ Q Information but Declined by Proponent 2018 Dockweiler FOR The 2018 Dockweiler FEIR determined the potential for earthquake -induced slope failure at the Approved Project Site is considered low provided that future geologic and geotechnical evaluations and recommendations for slope stability are incorporated into design and construction of the Approved Project. The 2018 Dockweiler FEIR also determined that the Approved Project Site is not susceptible to liquefaction - related hazards. As concluded in the Final EIR, the implementation of Mitigation Measure 4.5-1 and 4.5-2 would ensure that potential impacts associated with geotechnical stability would be reduced to a less than significant level. Proposed Project The Proposed Project is not located within an Alquist-Priolo Earthquake Fault Zone.19 Additionally, the Norland Drive site is relatively flat and is not located within an identified landslide zone.20 However, the Norland Drive site is located within an area that is susceptible to liquefaction hazards.21 Similar to the Approved Project, the Proposed Project would implementation Mitigation Measure 4.5-1 and 4.5-2 would ensure that potential impacts associated with geotechnical stability would be reduced by requiring compliance with the County and State Building Codes and shall adhere to all modern earthquake standards. Therefore, there would be no new or greater impacts than those identified in the 2018 FEIR. 19 California State Geoportal, "CGS Seismic Hazards Program: Alquist-Priolo Fault Hazard Zones."

As concluded in the Final EIR, the implementation of Mitigation Measure 4.5-1 and 4.5-2 would ensure that potential impacts associated with geotechnical stability and earthwork would be reduced to a less than significant level. Proposed Project The Proposed Project would not result in the exacerbation of any substantial adverse effects related to earthquake/seismic shaking, ground failure or result in the substantial erosion or loss of topsoil. According to USGS, the site geology is currently composed of Miocene non marine rock.22 As with the Approved Project, the Proposed Project would include implementation of the 2018 Dockweiler FEIR Mitigation Measure 4.5-1 ensuring that the Proposed Project shall be designed and constructed in accordance with the County and State Building Codes and shall adhere to all modern earthquake standards. Therefore, there would be no new or greater impacts than those identified in the 2018 FEIR. Does the currently Proposed Project require Subsequent or Supplemental CEQA Documentation with respect to the following: 22 California Department of Conservation, "Geologic Map of California."

Proposed Project Consistent with the analysis and conclusions of the 2018 Dockweiler FEIR, Mitigation Measure 4.4-2 would continue to reduce impacts related to the destruction of unique paleontological resources or unique geologic features below the level of significance; there would be no new or greater impacts than those identified in the 2018 FEIR. H. GREENHOUSE GAS EMISSIONS Greenhouse gas emissions associated with the Proposed Project were evaluated based on a review of the 2018 Dockweiler FEIR. The potential for the Proposed Project to result in new or substantially more adverse significant impacts related to greenhouse gas emissions was evaluated in relation to two questions recommended for consideration by the State CEQA Guidelines. Impact Sciences, Inc. 58 Placerita Yard Relocation Project 1250.020 Lyons AvenuelDockweiler Drive Extension Final EIR 2nd Addendum 3. Environmental Setting & Impact Analysis Does the currently Proposed Project require Subsequent or Supplemental CEQA Documentation with respect to the following: (a) Generate greenhouse gas emissions, either directly or indirectly, that may have a significant impact on the environment (b) Conflict with an applicable plan, policy or regulation adopted for the purpose of reducing the emissions of greenhousegases? Yes No New Significant Environmental Effect Caused by a Change in the ❑ Q Project or Circumstances Substantial Increase in the Severity of a Previously Identified ❑ .7 Significant Effect Caused by a Change in the Project or Circumstances New or Substantially More Severe Significant Impacts Shown by ❑ Q New Information Ability to Ability to Substantially Reduce a Significant Effect Shown ❑ .7 by New Information but Declined by Proponent 2018 Dockweiler FEIR The 2018 Dockweiler FEIR determined there was no evidence that the Approved Project would cause significant environmental impact in regard to greenhouse gas emissions. Proposed Project The Proposed Project would relocate the existing maintenance yard located at 22234 Placerita Canyon Road to 15601 Norland Drive. Operations of the Placerita maintenance yard would take place at a new location; no new or expanded operations are proposed with the Proposed Project. Like the determination of the 2018 Dockweiler FEIR, the Proposed Project is consistent with the applicable General Plan and would not require a zone change or General Plan amendment. As such, the Proposed Project would not have the potential to generate substantive GHG emissions and would not conflict with any applicable plans, policies, or regulations adopted for the purpose of reducing the emissions of greenhouse gases. There would be no new or greater impacts than those identified in the 2018 Dockweiler FEIR. I. HAZARDS AND HAZARDOUS MATERIALS Hazards and hazardous materials of the Proposed Project were evaluated based on a review of the studies included in the 2018 Dockweiler FEIR. Impacts were evaluated and compared to impacts identified in the 2018 Dockweiler FEIR and the required mitigation measures. Hazardous waste can pose a potential or substantial hazard to human health or the environment when improperly managed. Designated hazardous waste possesses at least one of four defined characteristics-ignitability, corrosivity, reactivity, or toxicity - or appears on special U.S. Environmental Protection Agency lists. The potential for the Proposed Project to result in new or substantially more adverse significant impacts related to hazards and hazardous materials was evaluated in relation to eight questions recommended for consideration by the State CEQA Guidelines. Impact Sciences, Inc. 59 Placerita Yard Relocation Project 1250.020 Lyons AvenuelDockweiler Drive Extension Final EIR 2nd Addendum 3. Environmental Setting & Impact Analysis The 2018 Dockweiler FEIR addressed the Approved Project's impacts related to Hazards and Hazardous Materials in Section 5.1, Impacts Determined to be Less Than Significant, and in Appendix A, Notice of Preparation and CEQA Initial Study Checklist (July 2013). Although each impact was not specifically addressed, impacts as they pertain to Hazards and Hazardous Materials were found to collectively be less than significant, with some impact questions addressed and some left unaddressed. Does the Proposed Project require Subsequent or Supplemental CEQA Documentation with respect to the following: (a) Create a significant hazard to the public or the environment through the routine transport, use, or disposal of hazardous materials? (d) Be located on a site which is included on a list of hazardous materials sites compiled pursuant to Government Code Section 65962.5 and, as a result, would it create a significant hazard to the public or the environment? Yes No New Significant Environmental Effect Caused by a Change in the ❑ .7 Project or Circumstances Substantial Increase in the Severity of a Previously Identified ❑ Q Significant Effect Caused by a Change in the Project or Circumstances New or Substantially More Severe Significant Impacts Shown by New ❑ Q Information Ability to Substantially Reduce a Significant Effect Shown by New ❑ .7 Information but Declined by Proponent 2018 Dockweiler FEIR The 2018 Dockweiler EIR determined that the Approved Project would not require the transport, use, or disposal of potentially hazardous materials. Additionally, the 2018 Dockweiler EIR did not identify any properties within or immediately adjacent to the Approved Project Site that is included on a list of hazardous materials sites compiled pursuant to Government Code Section 65962.5. Therefore, impacts were found to be less than significant. Proposed Project No identified Envirostor hazardous waste or cleanup sites pursuant to Government Code Section 65962.5 have been identified on 15601 Norland Drive.23 Therefore, the site is not included on a list of hazardous materials sites compiled pursuant to Government Code Section 65962.5. However, the Norland Drive site does exhibit evidence of previous disturbance supported by an old asphalt. A Phase II Environmental Site Assessment (ESA) prepared as part of the County's due diligence efforts (see Appendix B) indicates dumping of construction debris including asphalt, wood, bricks, concrete, household trash, etc. on the site. Any construction activity would occur in accordance with County, State and federal requirements related 23 California Environmental Protection Agency, "Cortese List Data Resources."

Impact Sciences, Inc. 60 Placerita Yard Relocation Project 1250.020 Lyons Avenue/Dockweiler Drive Extension Final EIR 2nd Addendum 3. Environmental Setting & Impact Analysis to removal of hazardous materials. Therefore, no new or greater impacts would occur compared to the 2018 Dockweiler FEIR. Limited amounts of some hazardous materials could be transported during the short-term construction phase of the Project and could expose construction workers and the general public (e.g., diesel, paints, solvents), vehicle fuel, and other hazardous materials. However, these uses would be typical of construction sites and would be similar to what would occur as part of the Approved Project. In the event of a release of hazardous material the Project would be required to notify the following State agencies under the following State statutes, respectively: • Department of the California Highway Patrol: California Vehicle Code Section 23112.5; • Office of Emergency Services and the California Public Utilities Commission: Public Utilities Code Section 7673, (PUC General Orders #22-13, 161); • State Fire Marshal: Government Code Sections 51018 • Office Emergency Services: Water Codes Sections 13271, 13272; and • Division of Occupational Safety and Health (Cal/OSHA): California Labor Code Section 6409.1 (b)10. Compliance with these statutes would reduce the Proposed Project's impacts related to location on a hazardous waste site to less than significant. Therefore, no mitigation would be required and there would be no new or greater impacts than those identified in the 2018 Dockweiler FEIR. Does the Proposed Project require Subsequent or Supplemental CEQA Documentation with respect to the following: (b) Create a significant hazard to the public or the environment through reasonably foreseeable upset and accident conditions involving the release of hazardous materials into the environment? (c) Emit hazardous emissions or handle hazardous or acutely hazardous materials, substances, or waste within one -quarter mile of an existing or proposed school?

However, the 2018 Dockweiler FEIR did not provide a specific analysis or conclude the Approved Project's impacts related to creating a significant hazard to the Impact Sciences, Inc. 61 Placerita Yard Relocation Project 1250.020 Lyons AvenuelDockweiler Drive Extension Final EIR 2nd Addendum 3. Environmental Setting & Impact Analysis public or the environment through reasonably foreseeable upset and accident conditions, nor were the Approved Project's impacts related to emitting hazards near schools analyzed. Proposed Project The closest existing school to the Norland Drive site is the Sulphur Springs Elementary School, located 0.8 miles to the southwest. There are no planned school projects within the vicinity of the Norland Drive site.24 As such, the Project would not emit hazardous emissions or handle hazardous or acutely hazardous materials, substances, or waste within one -quarter mile of an existing or proposed school and there would be no new or greater impacts than those identified in the 2018 Dockweiler FEIR. Does the Proposed Project require Subsequent or Supplemental CEQA Documentation with respect to the following: (e) Be located within an airport land use plan or, where such a plan has not been adopted, within two miles of a public airport or public use airport, would the project result in a safety hazard for people residing or working in the Project Area? (f) Be located within the vicinity of a private airstrip, would the project result in a safety hazard for people residing or working in the Project Area?

Accordingly, the 2018 Dockweiler FEIR did not provide a specific analysis or conclude the Approved Project's impacts related to a public or private airstrip. However, the 2018 Dockweiler FEIR did conclude that the Approved Project would not be two miles of a public airport or public use airport. Proposed Project Similar to the Approved Project analyzed in the 2018 Dockweiler FEIR, Norland Drive site is not near a public or private airstrip nor is it within an airport land use plan. Thus, the Proposed Project would have 24 City of Santa Clarita, "Major Development Projects."

Environmental Setting & Impact Analysis no impacts related to airport land use. Therefore, there would be no new or greater impacts than those identified in the 2018 Dockweiler FEIR. Does the Proposed Project require Subsequent or Supplemental CEQA Documentation with respect to the following: (g) Impair implementation of or physically interfere with an adopted emergency response plan or emergency evacuation plan? Yes No New Significant Environmental Effect Caused by a Change in the ❑ .7 Project or Circumstances Substantial Increase in the Severity of a Previously Identified ❑ .7 Significant Effect Caused by a Change in the Project or Circumstances New or Substantially More Severe Significant Impacts Shown by ❑ .7 New Information Ability to Substantially Reduce a Significant Effect Shown by New ❑ .7 Information but Declined by Proponent 2018 Dockweiler FEIR Construction of the Approved Project involves buildout of a roadway extension that was identified in the City's Circulation Element of the General Plan. Thus, the Approved Project would not impair implementation of or physically interfere with an adopted emergency response plan or emergency evacuation plan, and impacts would be less than significant. As such, no impacts would occur. Proposed Project The Proposed Project would not impede existing emergency and evacuation plans. The Norland Drive site would be accessed by Norland Drive, which is not an identified emergency route in the County.25 Further, emergency access to and from the Norland Drive site would adhere to all regulatory requirements of the County. Thus, the Proposed Project would not impair the implementation of or physically interfere with an adopted emergency response plan or emergency evacuation plan and there would be no new or greater impacts than those identified in the 2018 Dockweiler FEIR. 25 Los Angeles County Public Works, "Disaster Route Maps (by City)."

Environmental Setting & Impact Analysis Does the Proposed Project require Subsequent or Supplemental CEQA Documentation with respect to the following: (h) Expose people or structures, either directly or indirectly, to a significant risk of loss, injury or death involving wildland fires? Yes No New Significant Environmental Effect Caused by a Change in the ❑ .7 Project or Circumstances Substantial Increase in the Severity of a Previously Identified ❑ Q Significant Effect Caused by a Change in the Project or Circumstances New or Substantially More Severe Significant Impacts Shown by ❑ .7 New Information Ability to Substantially Reduce a Significant Effect Shown by New ❑ Q Information but Declined by Proponent 2018 Dockweiler FEIR As stated, impacts related to Hazards and Hazardous Materials were generalized in the 2018 Dockweiler FEIR. Accordingly, the 2018 Dockweiler FEIR did not provide a specific analysis or conclude the Approved Project's impacts related to wildland fires. Proposed Project The Norland Drive site is within a Fire Hazard Severity Zone in a State Responsibility Area (FHSZ in SRA) categorized as 'Very High.'26 As previously mentioned, other than minor repairs, no heavy vehicle maintenance, servicing, or refueling would take place. Therefore, no fuel storage tanks or vehicle maintenance bays that may require the storage and use of petroleum products and solvents will be included as part of the Proposed Project, making fire risks associated with the presence of petroleum -based fuels less than significant. Additionally, the Proposed Project would comply with the provisions of Title 32, Section 326, Activities in Wildfire Risk Areas, which includes Section 326.7, Fire Protection Facilities Required.27 Section 326.7 establishes required fire protection facilities as well as conditions and/or limitations that are necessary to maintain reasonable fire safety, which includes but is not limited to the removal of dry grass and weeds from around buildings, along roadways, and automobile parking areas, providing adequate water supply, pumps, hydrants, and hoses, as well as including firebreaks as necessary to prevent a fire on the premises from spreading to adjacent brush or grass -covered areas.28 Lastly, as best practice and as the 26 Cal Fire, "Fire Hazard Severity Zone Viewer."

Environmental Setting & Impact Analysis lead agency, the County would ensure that the Proposed Project would incorporate wildfire -reduction BMPs included in the LACDPW Construction Site BMPs Manual and adhere to the policies related to minimizing fire risks to existing and new land uses that were established in the Fire Hazard Planning and Technical Advisory published by the OPR.29,30 Compliance with regulations established in the County Code, the Fire Hazard Planning and Technical Advisory, and BMPs established in the LACDPW Construction BMPs Manual would ensure that implementation of the proposed Project would not expose people or structures to wild land fires. Impacts would be less than significant, and no new or greater impacts would occur. J. HYDROLOGY AND WATER QUALITY Hydrology and water quality impacts of the Proposed Project were evaluated in relation to the 2018 Dockweiler FEIR and required mitigation measures established in the 2011 OVOV FEIR. The potential for the Proposed Project to result in new or substantially more adverse significant impacts related to hydrology and water quality was evaluated in relation to 8 questions recommended for consideration by the State CEQA Guidelines. Does the Proposed Project require Subsequent or Supplemental CEQA Documentation with respect to the following: (a) Violate any water quality standards or waste discharge requirements or otherwise substantially degrade surface or ground water quality? (b) Substantially decrease groundwater supplies or interfere substantially with groundwater recharge such that the project may impede sustainable groundwater management of the basin? (e) Conflict with or obstruct implementation of a water quality control plan or sustainable groundwater managementplan?

Impact Sciences, Inc. 65 Placerita Yard Relocation Project 1250.020 Lyons Avenue/Dockweiler Drive Extension Final EIR 2nd Addendum 3. Environmental Setting & Impact Analysis would be required to have a project -Specific Standard Urban Storm Water Mitigation Plan (SUSMP) in place during the operational life of the Approved Project to address the management of runoff from the proposed roadway extension. Implementation of the SUSMP ensures are reduction of impacts to water quality, making operations of the Project less than significant. However, the 2018 Dockweiler FEIR did not discuss the Approved Project's impacts on groundwater supplies, groundwater recharge, and consistency with the Basin's groundwater management plan or water quality control plan. Proposed Project With implementation of the adopted Mitigation Measure 3.12-1 and Mitigation Measures 3.12: 3 through 3.12-5 established in the 2011 OVOV FEIR to reduce impacts on hydrology and water quality and compliance with existing regulations, the Proposed Project would result in less than significant impacts with respect to violating any water quality standards or waste discharge requirements. These mitigation measures include prohibiting alterations of floodways and channelization and design standards for development within a riverine floodplain. The Proposed Project would entail both construction and operational elements. The clearing of the 15601 Norland Drive could contribute to erosion, sediment -laden runoff, discharge of non -storm water runoff, or other water quality —related events. All construction activities would include implementation of best management practices (BMPs) to reduce or eliminate non - storm discharges to the storm water system. Implementation of BMPs would result in meeting the water quality standards set forth by responsible agencies, and would address storm runoff quantity and flow rate, suspended solids (primarily from erosion), and contaminants such as phosphorus and hydrocarbons. BMPs from the County's Construction Site BMPS's Manual31 would be incorporated in accordance with the National Pollution Discharge Elimination System (NPDES permit issued to the County by the Regional Water Quality Control Board (RWQCB), the County Storm Water Management, and the County's General Plan. Since the currently Proposed Project would be operating at the same capacity as the current maintenance yard; impacts regarding a decrease in groundwater supplies and quality would be less than significant. Development of the replacement maintenance yard would not conflict with the County's Urban Water Management Plan or the Los Angeles Regional Water Quality Control Board's Basin Plan. The Proposed Project would not pose any new or greater impacts than those identified in the certified 2018 Dockweiler FEIR. 31 Los Angeles County Department of Public Works, Construction Site Best Management Practices Manual, August 2010.

Environmental Setting & Impact Analysis Does the Proposed Project require Subsequent or Supplemental CEQA Documentation with respect to the following: (c) Substantially alter the existing drainage pattern of the site or area, including through the alteration of the course of a stream or river or through the addition of impervious surfaces in a manner which would: (i) result in substantial erosion or siltation on- or off -site? (ii) substantially increase the rate or amount of surface runoff in a manner which would result in flooding on- or off -site? (iii) create or contribute runoff water which would exceed the capacity of existing or planned stormwater drainage systems or provide substantial additional sources of polluted runoff? (iv) impede or redirect flood flows? Yes No New Significant Environmental Effect Caused by a Change in the ❑ .7 Project or Circumstances Substantial Increase in the Severity of a Previously Identified ❑ .7 Significant Effect Caused by a Change in the Project or Circumstances New or Substantially More Severe Significant Impacts Shown by ❑ .7 New Information Ability to Substantially Reduce a Significant Effect Shown by New ❑ .7 Information but Declined by Proponent 2018 Dockweiler FEIR Construction During construction, sediment is typically the constituent of greatest potential concern. The 2018 Dockweiler FEIR states that development projects within the City of Santa Clarita are required to prepare and implement a SWPPP, in accordance with the NPDES General Permit for Discharges of Storm Water Associated with Construction Activity and Land Disturbance Activities. The site -specific SWPPP would be prepared prior to earthwork activities and would be implemented and monitored for compliance during project construction activities. The SWPPP would include BMPs and erosion control measures to prevent pollution in storm water discharge. Typical BMPs that could be used during construction include good -housekeeping practices (e.g., street sweeping, proper waste disposal, vehicle and equipment maintenance, concrete washout area, materials storage, minimization of hazardous materials, proper handling and storage of hazardous materials, etc.) and erosion/sediment control measures (e.g., silt fences, fiber rolls, gravel bags, storm water inlet protection, and soil stabilization measures, etc.). The SWPPP would be subject to review and approval by the City for compliance with the City's Stormwater and Urban Runoff Pollution Control and Section 10.04.070 of the City's Municipal Code. Additionally, all Approved Project construction activities would comply with the City's grading permit regulations, which require the implementation of grading and dust control measures, including a wet weather erosion control plan if construction occurs during rainy season, as well as inspections to ensure that sedimentation and erosion is minimized. The site specific BMPs that are required to be incorporated into the Project's SWPPP are identified below in Section (3), Regulatory Impact Sciences, Inc. 67 Placerita Yard Relocation Project 1250.020 Lyons AvenuelDockweiler Drive Extension Final EIR 2nd Addendum 3. Environmental Setting & Impact Analysis Compliance. Therefore, through compliance with NPDES requirements and City grading regulations, the Approved Project's construction impacts related to water quality would not violate any water quality standards or waste discharge requirements or otherwise substantially degrade water quality. Construction - related impacts to hydrology and water quality would therefore be less than significant. Operation The 2018 Dockweiler FEIR determined that once the Approved Project has been constructed, urban runoff could include the above -mentioned contaminants. Trace metals from road surface runoff and landscape maintenance debris may be mobilized in storm runoff and in dry -season in "nuisance flows' from landscape irrigation. Liquid product spills occurring at the Project Site could also enter the storm drain. Dry product spills could enter the storm drain via runoff in wet weather conditions or dry -season "nuisance flows. The Approved Project Site is generally pervious. In accordance with NPDES requirements, the Project Applicant would be required to have a Project -specific SUSMP in place during the operational life of the Project to address the management of runoff from the proposed roadway extension. The SUSMP would include site design, source control, low -impact development, and treatment control BMPs and would address site design BMPs (such as minimizing impervious areas, maximizing permeability, minimizing directly connected impervious areas, and creating reduced or "zero discharge" areas); incorporate applicable source control BMPs; incorporate treatment control BMPs as described in the Los Angeles County SUSMP; describe long-term operation and maintenance requirements for the treatment control BMPs; and describe the mechanism for funding the long-term operation and maintenance of the treatment control BMPs. The final selection of BMPs would be completed through coordination with the City. Also, per the NPDES, the storm water quality plan would be subject to review and approval by the City for compliance with the City's Development Best Management Practices Handbook, Low Impact Development Manual, Part B Planning Activities. Therefore, implementation of the storm water quality plan as discussed above water quality impacts during operation would be less than significant. Proposed Project The Norland Drive site is located within a Special Flood Hazard Area Regulatory Floodway due to its proximity to the Santa Clara River.32 Like the Approved Project, the Proposed Project would be subject to 32 FEMA, FEMA Flood Map Service Center, 2021.

Impact Sciences, Inc. 68 Placerita Yard Relocation Project 1250.020 Lyons Avenue/Dockweiler Drive Extension Final EIR 2nd Addendum 3. Environmental Setting & Impact Analysis all applicable regulations related to the reducing the potential to alter existing drainage patterns, including implementation of erosion and sediment control BMPs and adherence to County regulations, including the County Code. Construction and operational activities associated with the Proposed Project would result in less than significant erosion and siltation impacts with adherence to mitigation measures and development regulations, such as County Code Title 22, Chapter 22.118, Flood Control, and other regulations related to drainage patterns, erosion, siltation, rate of runoff, capacity of the drainage system or substantial sources of polluted runoff (see Mitigation Measures 3.12-1 through 3.12-5 of the 2011 OVOV FEIR). These mitigation measures include prohibiting alterations of floodways and channelization and design standards for development within a riverine floodplain. Therefore, no additional mitigation would be required and there would be no new or greater impacts than those identified in the 2018 Dockweiler FEIR. Does the Proposed Project require Subsequent or Supplemental CEQA Documentation with respect to the following: (d) In flood hazard, tsunami, or seiche zones, risk release of pollutants due to ro'ect inundation? Yes No New Significant Environmental Effect Caused by a Change in the ❑ Q Project or Circumstances Substantial Increase in the Severity of a Previously Identified ❑ Q Significant Effect Caused by a Change in the Project or Circumstances New or Substantially More Severe Significant Impacts Shown by ❑ Q New Information Ability to Substantially Reduce a Significant Effect Shown by New ❑ Q Information but Declined by Proponent 2018 Dockweiler FEIR The 2018 Dockweiler Initial Study assessed the Approved Project's potential impacts of placing development, including housing, within a 100-year flood plain as mapped on a federal Flood Hazard Boundary or a Flood Insurance Map or other flood hazard delineation maps. The 2018 Dockweiler Initial Study determined that the Approved Project would not involve the construction of habitable structures. Therefore, the Approved Project would not place housing within an area susceptible to flooding or mudflows. No impact would occur in regard to this issue. Proposed Project Unlike the 2018 Dockweiler FEIR, the Norland Drive site is located within a Special Flood Hazard Area Regulatory Floodway.33 As mitigation measures pertaining to development within a flood zone would not have been provided in the 2018 Dockweiler FEIR, the Proposed Project will incorporate Mitigation 33 FEMA, FEMA Flood Map Service Center, 2021.

Impact Sciences, Inc. 69 Placerita Yard Relocation Project 1250.020 Lyons Avenue/Dockweiler Drive Extension Final EIR 2nd Addendum 3. Environmental Setting & Impact Analysis Measures 3.12-3 and 3.12-5 of the 2011 OVOV FEIR that were previously adopted by the County to ensure that impacts are less than significant related to flood hazards. Mitigation Measure 3.12-3 states that all structures be flood -proofed from the 100-year storms by elevating the structure so that the lowest floor is at or above the Base Flood Elevation in accordance with the effective Flood Insurance Rate Map. Mitigation Measure 3.12-5 states that any development that is located within a Regulatory Floodway must not increase base flood elevations and requires a hydrologic and hydraulic analysis prior to the start of development and must demonstrate that the development would not cause any rise in base flood levels and not allow any rise within regulatory floodways. In accordance with the mitigation measures, the modular buildings proposed would be on stilts to elevate the buildings to a level that would not be impacted by a potential flood. Further, this facility would not be accessible to the public and would be restricted to County Public Works Department staff. Although many of the structures on site will be cargo containers and modular buildings, the Proposed Project would be consistent with all required regulations regarding development within flood areas and preserving water quality and, to further minimize risks, would incorporate BMPs established by the County as well as mitigation measures provided in the 2011 OVOV FEIR. Despite the Norland Drive site being located in a flood zone, the Proposed Project would not exacerbate flood risks in the area and would comply with all regulations related to development in a flood zone. Therefore, there would be no new or greater impacts than those identified in the 2018 Dockweiler FEIR. K. LAND USE AND PLANNING Land use and planning impacts of the Proposed Project were evaluated in light of the 2018 Dockweiler FEIR. The potential for the Proposed Project to result in new or substantially more adverse significant impacts related to land use and planning was evaluated in relation to two questions recommended for consideration by the State CEQA Guidelines.

Environmental Setting & Impact Analysis Proposed Project The Proposed Project is the relocation of the County's Placerita maintenance yard to 15601 Norland Drive. The need for the relocation is due to the City's approved roadway improvements. 15601 Norland Drive is vacant and largely undeveloped and is located adjacent to the SR 14 roadway. No homes are located in the vicinity of the Norland Drive site that could be divided by the Proposed Project. Therefore, the Proposed Project would be consistent with the analysis and conclusions of the 2018 Dockweiler FEIR and there would be no impact related to land use and planning resulting in a physical division to the established community. Therefore, there would be no new or greater impacts than those identified in the 2018 Dockweiler FEIR. (b) Does the Proposed Project require Subsequent or Supplemental CEQA Documentation with respect to causing a significant environmental impact due to a conflict with any land use plan, policy, or regulation adopted for the purpose of avoiding or mitigating an environmental effect? Yes No New Significant Environmental Effect Caused by a Change in the ❑ Q Project or Circumstances Substantial Increase in the Severity of a Previously Identified ❑ Q Significant Effect Caused by a Change in the Project or Circumstances New or Substantially More Severe Significant Impacts Shown by New ❑ Q Information Ability to Substantially Reduce a Significant Effect Shown by New ❑ Q Information but Declined by Proponent 2018 Dockweiler FEIR The 2018 Dockweiler FEIR found the Approved Project would not conflict with applicable land use plans, policies, or regulations. Proposed Project The Proposed Project would relocate the existing maintenance yard to 15601 Norland Drive due to roadway improvements in the vicinity of the current maintenance yard. The land use and zoning designation for the 15601 Norland Drive parcel is Open Space (OS) which allows for the development of a use such as a maintenance yard.34,35 The relocation of the Placerita maintenance yard would be consistent with all 34 City of Santa Clarita, "Mapping Your City - Santa Clarita's Web -Based Mapping Tool."

Environmental Setting & Impact Analysis applicable plans, polices and regulations and there would be no new or greater impacts than those identified in the 2018 Dockweiler FEIR. L. MINERAL RESOURCES The potential for the Proposed Project to result in new or substantially more adverse significant impacts to mineral resources than what was evaluated in relation to the 2018 Dockweiler FEIR and two questions recommended for consideration by the State CEQA Guidelines. Does the Proposed Project require Subsequent or Supplemental CEQA Documentation with respect to the following: (a) Result in the loss of availability of a known mineral resource that would be of value to the region and the residents of the state? (b) Result in the loss of availability of a locally -important mineral resource recovery site delineated on a local general plan, specific plan or other land useplan? Yes No New Significant Environmental Effect Caused by a Change in the ❑ Q Project or Circumstances Substantial Increase in the Severity of a Previously Identified ❑ .7 Significant Effect Caused by a Change in the Project or Circumstances New or Substantially More Severe Significant Impacts Shown by ❑ Q New Information Ability to Substantially Reduce a Significant Effect Shown by New ❑ .7 Information but Declined by Proponent 2018 Dockweiler FEIR The 2018 Dockweiler FEIR determined that impacts to mineral resources were less than significant. The Approved Project was not within a known source area for aggregate or other mineral resources. Development of the Approved Project would not result in the loss of availability of a known mineral resource that would be of value to the region and the residents of the State. Additionally, development of the Approved Project would not result in the loss of availability of a locally important mineral resource recovery site. Proposed Project The Norland Drive site is located within an MRZ-2 zone, an area where geologic information indicates the presence of significant Portland cement concrete aggregate resources.36 Although mineral resources may exist on -site, recovery of such resources is not anticipated; though the Norland Drive site is within a mineral 36 California Geologic Survey, Updated Mineral Resource Zones for Portland Cement Concrete Aggregate in the San Fernando Valley and Saugus -Newhall Production -Consumption Regions, 2021.

Impact Sciences, Inc. 72 Placerita Yard Relocation Project 1250.020 Lyons Avenue/Dockweiler Drive Extension Final EIR 2nd Addendum 3. Environmental Setting & Impact Analysis resource classification of MRZ-2, the site is not currently nor has it ever been used to extract aggregate resources. Further, the design of the project (i.e., use of modular/not permanent structures) would not preclude the recovery of mineral resources from the site in the future. The Proposed Project would involve nominal earthwork activities (i.e., paving) and would have limited opportunity to impact any aggregate resources that could potentially be on -site and would not impede future extraction. Further, the U.S. Geological Survey (USGS) also has focused on identifying areas that may have the potential to contain critical mineral resources. Mapping of focus areas was based on a framework of mineral systems and their associated mineral deposit types that could possibly host critical minerals. USGS Mineral Resources Data Map shows there are no critical minerals within the Norland Drive site.37 Therefore, Project implementation would not result in the loss of a locally important mineral resource recovery site delineated on a local general plan, specific plan or other land use plan; and the Proposed Project would result in no impacts in relation to mineral resources, consistent with the 2018 Dockweiler FEIR. No new or greater impacts would occur. M. NOISE The potential for the Proposed Project to result in new or substantially more adverse significant impacts related to noise was evaluated in relation to the 2018 Dockweiler FEIR and six questions recommended for consideration by the State CEQA Guidelines. 37 USGS, Mineral Resources Online Spatial Data. Available online at: https:Hmrdata.usgs.gov/general/map-us.html, accessed August 16, 2024. Impact Sciences, Inc. 73 Placerita Yard Relocation Project 1250.020 Lyons Avenue/Dockweiler Drive Extension Final EIR 2nd Addendum 3. Environmental Setting & Impact Analysis Does the Proposed Project require Subsequent or Supplemental CEQA Documentation with respect to the following: (a) Generate a substantial temporary or permanent increase in ambient noise levels in the vicinity of the project in excess of standards established in the local general plan or noise ordinance, or applicable standards of other agencies? (b) Generate excessive groundborne vibration or groundborne noise levels? Yes No New Significant Environmental Effect Caused by a Change in the ❑ Q Project or Circumstances Substantial Increase in the Severity of a Previously Identified ❑ .7 Significant Effect Caused by a Change in the Project or Circumstances New or Substantially More Severe Significant Impacts Shown by ❑ Q New Information Ability to Substantially Reduce a Significant Effect Shown by New ❑ .7 Information but Declined by Proponent 2018 Dockweiler FOR Construction The Approved Project would require the use of heavy equipment for ground clearing, site grading, and roadway construction. Several pieces of construction equipment operating simultaneously would generate a noise level of approximately 94.6 dBA. The estimated construction noise levels impacting sensitive receptors are expected to exceed the City's daytime noise standards for residential uses (see Section 4.8, Noise, Table 4.8-9, Estimated Exterior Construction Noise at Nearest Sensitive Receptors, of the EIR). Notwithstanding implementation of Mitigation Measures 4.8-1 through 4.8-9, which would require best practices to reduce construction related noise, construction noise levels would still constitute a significant unavoidable impact. The Approved Project site clearing and grading activities would not occur within 100 feet of any occupied residential structure within the Project area. The nearest homes to the Approved Project are approximately 400 feet north of the Project site. These homes would be exposed to vibration levels in the range of 69 VdB, which is below the dividing line between barely perceptible and distinctly perceptible levels for many people. Construction activities that would occur within 300 feet of a residential zone would be limited to the hours of 7:00 A.M. through 7:00 P.M. Monday through Friday and 8:00 A.M. through 6:00 P.M. on Saturday. Therefore, vibration impacts would not occur during recognized sleep hours for residences. The Approved Project would not generate vibration levels in excess of the 80 VdB threshold at any residences and/or buildings where people normally sleep. Thus, the Proposed Project's potential impact upon exposing persons to excessive groundborne vibration or groundborne noise levels would be less than significant. Impact Sciences, Inc. 74 Placerita Yard Relocation Project 1250.020 Lyons AvenuelDockweiler Drive Extension Final EIR 2nd Addendum 3. Environmental Setting & Impact Analysis Operation Section 4.8, Noise, of the EIR, analyzed operational noise impacts resulting from the Approved Project. The changes in future noise levels along the study -area roadway segments in the project vicinity for the Approved Project near term (Year 2019) impacts would increase local noise levels by a maximum of 2.7 dBA CNEL (at the location of Dockweiler Drive (between Sierra Highway and Valle del Oro) (see Section 4.8, Noise, Table 4.8-11, Future (2019) Project Roadway Noise Impacts at Off -Site Locations, of the EIR). This increase would be below the identified thresholds of significance. At all other roadway segments, the resulting noise levels were determined to have an anticipated decrease. The EIR concluded that the Approved Project's potential to generate a substantial permanent increase in ambient noise levels in the project vicinity above existing levels would also be less than significant as the Approved Project would exclude the extension of Dockweiler Drive to Lyons Avenue but would include improvements to the intersection of Arch Street, 12th Street and Placerita Canyon Road, and at -grade railroad crossing and roadway improvements at the intersection of 13th Street and Railroad Avenue. Under the Approved Project, the Future (2019) With Project noise levels on the new roadway segment from Lyons Avenue to Valle del Oro are expected to be 63.3 dBA (CNEL) within 50 feet of the centerline of the roadway. The resulting noise levels at the three identified sensitive receptors would be below 52.9 dBA (see Section 4.8, Noise, Table 4.8-12, Estimated Roadway Noise at Nearest Sensitive Receptors, of the EIR). Thus, the anticipated with project noise levels at all off -site receptor locations would be within the "normally acceptable" range of noise for residential areas. The Approved Project would direct more traffic through Arch Street and 131h Street. The land uses along Arch Street and 13th Street are commercial properties and are not considered sensitive land uses for purposes of evaluating noise impacts. Thus, noise impacts associated with the change of traffic flows under the Approved Project would be less than significant. Proposed Project Construction Similar to the assumptions in the 2018 Dockweiler FEIR, the Proposed Project involves the same basic phases of construction and conventional construction equipment would be used, such as excavators, backhoes, and both light- and heavy-duty trucks. The Proposed Project generally requires less daily and total construction activity and associated equipment. As such, construction -related noise levels would be less than those disclosed for the Approved Project. Impact Sciences, Inc. 75 Placerita Yard Relocation Project 1250.020 Lyons AvenuelDockweiler Drive Extension Final EIR 2nd Addendum 3. Environmental Setting & Impact Analysis Furthermore, the 2018 Dockweiler FEIR identified noise -sensitive land uses within 130 feet of the Approved Project Site. The closest sensitive receptors to 15601 Norland Drive are located more than 400 feet to the north, across the Antelope Valley Freeway (SR 14). Given the distance to the closest sensitive receptor, construction noise impacts on sensitive receptors would be generally reduced under the Proposed Project. Thus, noise and vibration impacts from construction would be within those evaluated in the 2018 Dockweiler FEIR. The Proposed Project would implement Mitigation Measures 4.8-1 through 4.8-9. These mitigation measures are designed to minimize noise impacts during construction activities near sensitive receptors. They include restrictions on construction hours, requirements for advance notice to residents when work is close by and require noise control through proper equipment use and placement of construction activities. Additionally, they mandate the posting of construction schedules and a superintendent's contact information on -site, the use of quieter equipment where feasible, and the use of temporary noise barriers to protect nearby sensitive receptors from excessive noise. No additional mitigation would be required and there would be no new or greater impacts than those identified in the 2018 Dockweiler FEIR. Operation The Proposed Project could include new mechanical equipment, HVAC units and exhaust fans that could be audible to nearby sensitive receptors. However, the Proposed Project would be subject to compliance with Los Angeles County Code of Ordinances Section 12.08, which prohibits project mechanical equipment from elevating noise levels at nearby residences above 50 dB(A) and the nearest residential sensitive receptor is across the Antelope Valley Freeway over 400 feet away. Various noise events would occur periodically from the Project's storage and parking of vehicles. Automobile movements would comprise the most continuous noise source and would generate a noise level of approximately 65 dB(A) at a distance of 25 feet. Car alarm and horn noise events generate sound levels as high as 75 dB(A) at a reference distance of 25 feet, however these noise sources would be sporadic and there are no sensitive receptors located in close proximity to the Norland Drive site. Therefore, no additional mitigation would be required and there would be no new or greater stationary - source noise impacts than those identified in the certified 2018 FEIR. There would be no vibration impacts associated with operation of the Proposed Project. Therefore, no additional mitigation would be required and there would be no new or greater impacts than those identified in the certified 2018 Dockweiler FEIR. Impact Sciences, Inc. 76 Placerita Yard Relocation Project 1250.020 Lyons AvenuelDockweiler Drive Extension Final EIR 2nd Addendum 3. Environmental Setting & Impact Analysis Does the Proposed Project require Subsequent or Supplemental CEQA Documentation with respect to the following: (c) For a project located within -the vicinity of a private airstrip or -an airport land use plan or, where such a plan has not been adopted, within two miles of a public airport or public use airport, would the project expose people residing or working in the project area to excessive noise levels? Yes No New Significant Environmental Effect Caused by a Change in the ❑ .7 Project or Circumstances Substantial Increase in the Severity of a Previously Identified ❑ .7 Significant Effect Caused by a Change in the Project or Circumstances New or Substantially More Severe Significant Impacts Shown by ❑ .7 New Information Ability to Substantially Reduce a Significant Effect Shown by New ❑ Q Information but Declined by Proponent 2018 Dockweiler FEIR The 2018 Dockweiler FEIR concludes no impact with respect to noise from airports and airstrips. As indicated in the 2018 FEIR the Project Site for the Approved Project is neither located within two miles of a public or private airstrip nor is it located within an airport land use plan. Proposed Project The Norland Drive site is not located within two miles of a public or private airstrip nor is it located within an airport land use plan. Therefore, the Proposed Project would not change impacts as compared to the evaluation included in the 2018 FEIR. Therefore, there would be no new or greater impacts than those identified in the certified 2018 FEIR. N. POPULATION AND HOUSING Population and housing impacts of the Proposed Project were evaluated with regard to the 2018 Dockweiler FEIR. The potential for the Proposed Project to result in new or substantially more adverse significant was evaluated in relation to three questions recommended for consideration by the State CEQA Guidelines. The 2018 Dockweiler FEIR addressed the Approved Project's impacts related to Population and Housing in Section 5.1, Impacts Determined to be Less Than Significant, and in Appendix A, Notice of Preparation and CEQA Initial Study Checklist (July 2013). Impacts related to Population and Housing were generalized. Impact Sciences, Inc. 77 Placerita Yard Relocation Project 1250.020 Lyons AvenuelDockweiler Drive Extension Final EIR 2nd Addendum 3. Environmental Setting & Impact Analysis Does the currently Proposed Project require Subsequent or Supplemental CEQA Documentation with respect to the following: (a) Induce substantial unplanned population growth in an area, either directly (for example, by proposing new homes and businesses) or indirectly (for example, through extension of roads or other infrastructure)? (b) Displace substantial numbers of existing people or housing, necessitating the construction of replacement housing elsewhere? Yes No New Significant Environmental Effect Caused by a Change in the ❑ Q Project or Circumstances Substantial Increase in the Severity of a Previously Identified ❑ .7 Significant Effect Caused by a Change in the Project or Circumstances New or Substantially More Severe Significant Impacts Shown by ❑ Q New Information Ability to Substantially Reduce a Significant Effect Shown by New ❑ .7 Information but Declined by Proponent 2018 Dockweiler FEIR The 2018 Dockweiler FEIR concluded less than significant impacts would occur with respect to population, and no impact with respect to displacement of housing and people. No residential, commercial, or industrial land uses were proposed. Therefore, the Approved Project would not have the potential to induce substantial population growth in the area. Proposed Project The Proposed Project is a relocation of the County's Placerita maintenance yard and does not include any housing. Therefore, no new population would occur. Further, because the project is the relocation of an existing use, no new employment would result from the Proposed Project. The Norland Drive site is currently vacant and partially paved. No housing is present that would need to be removed or relocated. As such, the Proposed Project would not induce substantial unplanned population growth in an area, nor would it displace any existing housing. Therefore, there would be no impact to Population and Housing, and there would be no new or greater impacts than those identified in the 2018 Dockweiler FEIR. O. PUBLIC SERVICES Public Services impacts of the Proposed Project were evaluated based on a review of the 2018 Dockweiler FEIR. The potential for the Proposed Project to result in new or substantially more adverse significant impacts to public services was evaluated in relation to one question (relevant to each public service) recommended for consideration by the State CEQA Guidelines. The 2018 Dockweiler FEIR addressed the Approved Project's impacts related to Public Services in Section 5.1, Impacts Determined to be Less Than Significant, and in Appendix A, Notice of Preparation and CEQA Initial Study Checklist (July 2013). Impacts related to the Public Services were generalized. Impact Sciences, Inc. 78 Placerita Yard Relocation Project 1250.020 Lyons AvenuelDockweiler Drive Extension Final EIR 2nd Addendum 3. Environmental Setting & Impact Analysis (a) Does the Proposed Project require Subsequent or Supplemental CEQA Documentation with respect to substantial adverse physical impacts associated with the provision of new or physically altered governmental facilities, need for new or physically altered governmental facilities, the construction of which could cause significant environmental impacts, in order to maintain acceptable service ratios, response times or other performance objectives for any of the public services: (i) Fire protection? (ii) Police protection? (iii) Schools (iv) Parks (v) Other public facilities Yes No New Significant Environmental Effect Caused by a Change in the ❑ .7 Project or Circumstances Substantial Increase in the Severity of a Previously Identified ❑ .7 Significant Effect Caused by a Change in the Project or Circumstances New or Substantially More Severe Significant Impacts Shown by ❑ .7 New Information Ability to Substantially Reduce a Significant Effect Shown by New ❑ .7 Information but Declined by Proponent i and ii) Fire and Police Protection 2018 Dockweiler FEIR The 2018 Dockweiler FEIR determined that the Approved Project would not directly increase the demands for fire and police protection as the Approved Project does not include any new housing units or commercial uses. Adequate emergency access would be provided and facilitated, and the Approved Project would include new safety features aimed at reducing potential conflicts between pedestrians, vehicles and trains. As such, the Approved Project would not result in substantial adverse effects to the existing fire and police protection facilities, therefore no mitigation was required. Proposed Project The Proposed Project involves the relocation of the County's Placerita maintenance operation to a vacant, partially paved site at 15601 Norland Drive. The Proposed Project would not increase employment as it is a relocation of an existing use. Therefore, the Proposed Project would not lead to additional population growth in the area and the Proposed Project would not necessitate additional fire or police protection services. The Proposed Project would not result in any changes to the operations of local governmental facilities such as police protection or fire protection, and therefore would not create any additional demand for fire or police protection beyond what was analyzed. Therefore, there would be no new or greater impacts than those identified in the 2018 Dockweiler FEIR. Impact Sciences, Inc. 79 Placerita Yard Relocation Project 1250.020 Lyons AvenuelDockweiler Drive Extension Final EIR 2nd Addendum 3. Environmental Setting & Impact Analysis iii) Schools 2018 Dockweiler FEIR The 2018 Dockweiler FEIR indicated a less than significant impact on schools as a result of the implementation of the Approved Project. The Approved Project would not generate a substantial population increase. Therefore, the Approved Project would not generate an increased demand for school services and facilities. Proposed Project The Proposed Project is a relocation of the Placerita maintenance yard to 15601 Norland Drive and would not generate population; it would therefore have no impact on school facilities consistent with the evaluation in the 2018 Dockweiler FEIR. Therefore, there would be no new or greater impacts than those identified in the 2018 Dockweiler FEIR. iv) Parks 2018 Dockweiler FEIR As stated, the Approved Project would not generate population and, therefore, would not increase the demand for park facilities. Further, the Approved Project would not require potential property acquisitions of existing parkland. As such, the 2018 Dockweiler FEIR indicated a less than significant impact to parks as a result of the implementation of the Approved Project. Proposed Project The Proposed Project would not generate population increase; it would therefore have no impact on parks and recreational facilities consistent with the evaluation in the 2018 Dockweiler FEIR. There would be no new or greater impacts to parks than those identified in the 2018 Dockweiler FEIR. v) Other Public Facilities / Libraries 2018 Dockweiler FEIR As stated, the Approved Project would not generate a substantial population increase resulting in demand for other library facilities or services. As such, the 2018 Dockweiler FEIR indicates a less than significant impact on other public facilities as a result of the implementation of the Approved Project. Impact Sciences, Inc. 80 Placerita Yard Relocation Project 1250.020 Lyons AvenuelDockweiler Drive Extension Final EIR 2nd Addendum 3. Environmental Setting & Impact Analysis Proposed Project The Proposed Project would not generate population increase and would have no impact to other public facilities or libraries, consistent with the discussion in the 2018 Dockweiler FEIR. Therefore, there would be no new or greater impacts than those identified in the 2018 Dockweiler FEIR. P. RECREATION The potential for the Proposed Project to result in new or substantially more adverse significant impacts to recreation was evaluated in relation to the 2018 Dockweiler FEIR and two questions recommended for consideration by the State CEQA Guidelines. Does the currently Proposed Project require Subsequent or Supplemental CEQA Documentation with respect to the following: (a) Increased use of existing neighborhood and regional parks or other recreational facilities such that substantial physical deterioration of the facility would occur or be accelerated? (b) On -site recreational facilities or require the construction or expansion of recreational facilities which might have an adverse physical effect on the environment? Yes No New Significant Environmental Effect Caused by a Change in the ❑ Q Project or Circumstances Substantial Increase in the Severity of a Previously Identified ❑ .7 Significant Effect Caused by a Change in the Project or Circumstances New or Substantially More Severe Significant Impacts Shown by ❑ Q New Information Ability to Substantially Reduce a Significant Effect Shown by New ❑ .7 Information but Declined by Proponent 2018 Dockweiler FEIR According to the 2018 Dockweiler FEIR, there are no existing recreational facilities that are adjacent to the Approved Project Site. The Approved Project would not increase the use of existing regional parks, nor would the Approved Project require the expansion of recreational facilities. Therefore, no impacts to recreation as a result of the implementation of the Approved Project would occur. Proposed Project The Proposed Project would involve relocating the County's Placerita maintenance yard to 15601 Norland Drive. Because the Proposed Project would not generate any new population there would be no increase in demand for park facilities as a result of the Proposed Project. The Proposed Project would not require the expansion of regional parks or recreational facilities. Further, the Proposed Project does not include the construction of recreational facilities. The Proposed Project therefore would not have an impact on Impact Sciences, Inc. 81 Placerita Yard Relocation Project 1250.020 Lyons AvenuelDockweiler Drive Extension Final EIR 2nd Addendum 3. Environmental Setting & Impact Analysis recreational facilities consistent with the evaluation in the 2018 Dockweiler FEIR. Therefore, there would be no new or greater impacts than those identified in the 2018 Dockweiler FEIR. Q. TRANSPORTATION AND CIRCULATION Transportation and traffic impacts of the Proposed Project were evaluated in light of the 2018 Dockweiler FEIR. The potential for the Proposed Project to result in new or substantially more adverse significant impacts related to transportation and traffic was evaluated in relation to four questions recommended for consideration by the State CEQA Guidelines. As part of the 2018 State CEQA Guidelines updates, the checklist was revised to address consistency with State CEQA Guidelines Section 15064.3, subdivision (b), which relates to use of vehicle miles traveled (VMT) as the methodology for evaluating traffic impacts. The County published a VMT methodology in June 2020, updated September 2, 2020. Does the currently Proposed Project require Subsequent or Supplemental CEQA Documentation with respect to the following: (a) Conflict with a program plan, ordinance or policy addressing the circulation system, including transit, roadway, bicycle, and pedestrian facilities? (b) Would the project conflict or be inconsistent with CEQA Guidelines section 15064.3, subdivision (b)? Yes No New Significant Environmental Effect Caused by a Change in the ❑ Q Project or Circumstances Substantial Increase in the Severity of a Previously Identified ❑ Q Significant Effect Caused by a Change in the Project or Circumstances New or Substantially More Severe Significant Impacts Shown by ❑ Q New Information Ability to Substantially Reduce a Significant Effect Shown by New ❑ Q Information but Declined by Proponent 2018 Dockweiler FEIR The 2018 Dockweiler FEIR concludes less than significant impacts with respect to adopted plans and policies regarding transit or bicycle. The Approved Project would comply with the City's Circulation Element goals of enhancing the circulation system by providing bicycle lanes and accessibility to bicycle paths that are fundamental for a comprehensive transportation network. In further support of the Circulation Element, the Approved Project would provide an additional route of travel connecting Railroad Avenue to Dockweiler Drive. Construction of the Approved Project was estimated to occur over an approximate 12-month timeframe and would involve clearing, grading, excavation, trenching, and asphalt paving. Construction would require 4,990 cubic yards (cy) of cut, 2,760 cy of fill, and 2,230 cy of soil export associated with grading and excavation. Construction trips were estimated to be 125 trips per day based on truck capacity and cubic yards of material import and export during construction. Impact Sciences, Inc. 82 Placerita Yard Relocation Project 1250.020 Lyons AvenuelDockweiler Drive Extension Final EIR 2nd Addendum 3. Environmental Setting & Impact Analysis At the time that the Approved Project was analyzed, Vehicle Miles Traveled (VMT) was not the standard for analyzing impacts to traffic. However, 2018 Dockweiler FEIR did include information related to the Approved Project's consistency with a VMT based approach to CEQA analysis. In addition, the roadway improvement, Class II bike lanes, multiuse paths and pedestrian sidewalks would be provided to enhance non -auto travel safety and promote connectivity between The Master's University, the Newhall Metrolink Station and Old Town Newhall. This would aim to reduce trips and promote the use of other modes of transportation reducing VMT. Further, the Approved Project is recognized as a part of the regional strategy that is consistent with the SCAG's policies to reduce VMT. Because no land uses such as residential or commercial, are being proposed, the Approved Project would not generate any new vehicle trips and thus would not have the potential to increase VMTs on a per capita basis. Proposed Project Construction The Proposed Project would relocate the County's Placerita maintenance yard to 15601 Norland Drive. Construction of the Proposed Project would largely be limited to clearing and grading activities. A small number of construction trips would occur to and from the Norland Drive site to complete these activities, as well as one-time trips associated with moving the existing equipment to the new site, including the modular buildings. No import or export of soil would be necessary, compared to the approximately 125 haul truck trips that would be necessary for the Approved Project. Due to the small number of construction trips generated and the one time nature of the trips, they would be well within the assumptions of the much larger overall Approved Project Vehicle trips generated during construction would mainly stem from the movement of equipment of other structures from the existing maintenance yard. However, these trips would be nominal and would cease upon completion. Trips associated with construction of the Proposed Project would not exceed what was analyzed in the 2018 Dockweiler FEIR. Operation The Proposed Project would continue to operate at the capacity of the Placerita maintenance yard. No additional employees or operations would occur at the Norland Drive site. Vehicle trips to the Norland Drive site would be comparable to the Placerita maintenance yard. There would be no change to any intersection impacts identified in the Dockweiler EIR as the maintenance yard was assumed to be acquired as part of the Approved Project and therefore would not be operational and would have no effect on local trips. With regard to regional trips (i.e., VMT), the maintenance yard would continue to generate the same number of trips and at the regional level, there would be no change in VMT as a result of this change. Overall, the Approved Project was determined to reduce VMT and the change in the maintenance yard location would not change this finding. With a new location approximately 9.5 miles from the existing Impact Sciences, Inc. 83 Placerita Yard Relocation Project 1250.020 Lyons AvenuelDockweiler Drive Extension Final EIR 2nd Addendum 3. Environmental Setting & Impact Analysis location, the length of trips associated with maintenance activities could change. While some trips could be longer, other trips would likely be shorter, overall resulting in no change to VMT. Further, the County deploys team members based on a number of factors including proximity to job sites. As such, it is expected that overall trip lengths and number of trips would not change based on the relocation of the maintenance yard. Therefore, there would be no new or greater impacts under the Proposed Project. (c) Does the Proposed Project require Subsequent or Supplemental CEQA Documentation with respect to substantially increasing hazards due to a geometric design feature (e.g., sharp curves or dangerous intersections) or incompatible uses (e.g., farm equipment)? Yes No New Significant Environmental Effect Caused by a Change in the ❑ Q Project or Circumstances Substantial Increase in the Severity of a Previously Identified ❑ Q Significant Effect Caused by a Change in the Project or Circumstances New or Substantially More Severe Significant Impacts Shown by New ❑ Q Information Ability to Substantially Reduce a Significant Effect Shown by New ❑ Q Information but Declined by Proponent 2018 Dockweiler FOR The 2018 Dockweiler did not identify any potential hazards due to geometric design features, such as sharp curves or dangerous intersection, or incompatible uses. Proposed Project The Proposed Project would relocate the County's Placerita maintenance yard to 15601 Norland Drive. Ingress and egress would be designed to meet County roadway standards, allowing maintenance vehicles to enter and exit safely. Similar to the existing location, the Norland Drive site would not be accessible to the public and would be limited to use by County employees. As such, the Proposed Project would not introduce a new design feature that would increase hazards. Therefore, there would be no new or greater impacts than those identified in the certified 2018 Dockweiler FEIR. (d) Does the Proposed Project require Subsequent or Supplemental CEQA Documentation with respect to inadequate emergency access? Yes No New Significant Environmental Effect Caused by a Change in the ❑ Q Project or Circumstances Substantial Increase in the Severity of a Previously Identified ❑ Q Significant Effect Caused by a Change in the Project or Circumstances New or Substantially More Severe Significant Impacts Shown by New ❑ Q Information Ability to Substantially Reduce a Significant Effect Shown by New ❑ Q Information but Declined by Proponent Impact Sciences, Inc. 84 Placerita Yard Relocation Project 1250.020 Lyons AvenuelDockweiler Drive Extension Final EIR 2nd Addendum 3. Environmental Setting & Impact Analysis 2018 Dockweiler FEIR Construction of the Approved Project involves buildout of a roadway extension that was identified in the City's Circulation Element of the General Plan. Thus, the Approved Project would not impair implementation of or physically interfere with an adopted emergency response plan or emergency evacuation plan, and impacts would be less than significant. As such, no impacts would occur. Proposed Project As previously discussed in Hazards and Hazardous Materials, the Norland Drive location would be accessed by Norland Drive, which is not identified as a disaster route for the City. Further, emergency access to and from Norland Drive would adhere to all regulatory requirements of the Los Angeles County Fire Department (LACFD) for access points. No permanent lane closures or obstructions that could impede emergency response to or from the site from surrounding streets would occur with the Proposed Project. Consequently, the Proposed Project would result in a less than significant impacts related to emergency access and impacts. Therefore, there would be no new or greater impacts than those identified in the certified 2018 Dockweiler FEIR. R. TRIBAL CULTURAL RESOURCES Tribal Cultural Resources of the Proposed Project were evaluated with regard to the 2018 Dockweiler FEIR. Assembly Bill (AB) 52 went into effect on July 1, 2015, and requires that for a project for which a Notice of Preparation (NOP) for a Draft EIR was filed on or after July 1, 2015, the lead agency is required to consult with a California Native American tribe that is traditionally and culturally affiliated with the geographic area of a proposed project, if: (1) the tribe requested to the lead agency, in writing, to be informed by the lead agency of proposed projects in that geographic area; and (2) the tribe requests consultation, prior to the release of a negative declaration, mitigated negative declaration or environmental impact report for a project. The Notice of Preparation (NOP) for the Draft EIR was published on August 5, 2013, and therefore, the lead agency was not required to comply with the requirements of AB 52. AB 52 also required an update to Appendix G of the State CEQA Guidelines to include questions related to impacts to tribal cultural resources. Changes to Appendix G were approved by the Office of Administrative Law on September 27, 2016. The potential for the Proposed Project to result in new or substantially more adverse significant impacts was evaluated with respect to the 2018 Dockweiler FEIR and in relation to two questions recommended for consideration by the State CEQA Guidelines (see also Section E. Cultural Resources above). Impact Sciences, Inc. 85 Placerita Yard Relocation Project 1250.020 Lyons AvenuelDockweiler Drive Extension Final EIR 2nd Addendum 3. Environmental Setting & Impact Analysis Does the Proposed Project require Subsequent or Supplemental CEQA Documentation with respect to causing a substantial adverse change in the significance of a tribal cultural resource, defined in Public Resources Code section 21074 as either a site, feature, place, cultural landscape that is geographically defined in terms of the size and scope of the landscape, sacred place, or object with cultural value to a California Native American tribe, and that is: (i) Listed or eligible for listing in the California Register of Historical Resources, or in a local register of historical resources as defined in Public Resources Code section 5020.1(k), or (ii) A resource determined by the lead agency, in its discretion and supported by substantial evidence, to be significant pursuant to criteria set forth in subdivision (c) of Public Resources Code Section 5024.1. In applying the criteria set forth in subdivision (c) of Public Resource Code Section 5024.1, the lead agency shall consider the significance of the resource to a California Native American tribe. Yes No New Significant Environmental Effect Caused by a Change in the ❑ Q Project or Circumstances Substantial Increase in the Severity of a Previously Identified El Q Significant Effect Caused by a Change in the Project or Circumstances New or Substantially More Severe Significant Impacts Shown by New El Q Information Ability to Substantially Reduce a Significant Effect Shown by New El Q Information but Declined by Proponent 2018 Dockweiler FEIR The 2018 Dockweiler FEIR did not directly evaluate impacts related to Tribal Cultural Resources, but instead evaluated Tribal Cultural Resources as a part of Cultural Resources. The NOP for the Approved Project was released in 2013 and therefore preceded AB 52 and the CEQA amendments pertaining to the public notification requirements of Native American Tribes. Based on a records search conducted through the South Central Coastal Information Center, no archaeological sites were identified within a 1/2 mile radius of the Approved Project Site. As such, the Proposed Project would not have a direct impact upon known archaeological resources, including Native American tribal resources. However, as noted in the Native American Heritage Commissions response to the NOP, a lack of surface evidence of archaeological resources does not preclude their subsurface existence. As such, provisions for the identification and evaluation of accidentally discovery of tribal resources would be less than significant with the implementation of Mitigation Measure 4.4-1; this mitigation states that upon the discovery of any archaeological materials during the course of development, all construction is to be halted and requires the services of a qualified archaeologist to assess the materials and prepare a report evaluating its significance. The archaeologist's written assessment shall contain a detailed description of the materials encountered, and recommendations, if necessary, for the preservation, conservation, and relocation of the resource. With the incorporation of Mitigation Measure 4.4-1, impacts upon tribal resources would be less than significant. Impact Sciences, Inc. 86 Placerita Yard Relocation Project 1250.020 Lyons AvenuelDockweiler Drive Extension Final EIR 2nd Addendum 3. Environmental Setting & Impact Analysis Proposed Project As previously mentioned, the Approved Project did not separately evaluate potential impacts to Tribal Cultural Resources outside of the Cultural Resources section. Per Section 21080.3 of the State CEQA Guidelines and as described above, AB 52 consultation is not applicable to the Proposed Project and as such, no tribal consultation was undertaken. The Norland Drive location shows evidence of previous disturbance. Nonetheless, although limited ground disturbance would occur, the possibility to unearth human remains, and tribal cultural resources remains. Consistent with the 2018 Dockweiler FEIR, implementation of Mitigation Measure 4.4-1 would be applied to ensure that impacts to archaeological as well as tribal resources remain less than significant. Further, as the County or its designee would be performing any ground disturbing activities, the County would, as necessary, enlist trained experts in cultural and tribal cultural resources awareness to ensure appropriate treatment of any finds. Therefore, there would be no new or greater impacts than those identified in the certified 2018 Dockweiler FEIR. S. UTILITIES Utilities and service systems impacts of the Proposed Project were evaluated with regard to the 2018 Dockweiler FEIR. The potential for the Proposed Project to result in new or substantially more adverse significant impacts to utilities and service systems was evaluated in relation to seven questions recommended for consideration by the State CEQA Guidelines. Does the Proposed Project require Subsequent or Supplemental CEQA Documentation with respect to the following: (a) Require or result in the relocation or construction of new or expanded water, wastewater treatment or storm water drainage, electric power, natural gas, or telecommunications facilities, the construction or relocation of which could cause significant environmental effects? (b) Does the currently Proposed Project require Subsequent or Supplemental CEQA Documentation with respect to having sufficient water supplies available to serve the currently Proposed Project and reasonably foreseeable future development during normal, dry, and multiple dry years? (c) Does the currently Proposed Project require Subsequent or Supplemental CEQA Documentation with respect to resulting in a determination by the wastewater treatment provider which serves or may serve the Project that it has adequate capacity to serve the Project's projected demand in addition to the provider's existing commitments? (d) Generating solid waste in excess of State or local standards, or in excess of the capacity of local infrastructure, or otherwise impair the attainment of solid waste reduction goals? (e) Compliance with federal, state, and local management and reduction statutes and regulations related to solid waste? Yes No New Significant Environmental Effect Caused by a Change in the ❑ Q Project or Circumstances Substantial Increase in the Severity of a Previously Identified ❑ .7 Significant Effect Caused by a Change in the Project or Circumstances New or Substantially More Severe Significant Impacts Shown by ❑ Q New Information Impact Sciences, Inc. 87 Placerita Yard Relocation Project 1250.020 Lyons AvenuelDockweiler Drive Extension Final EIR 2nd Addendum 3. Environmental Setting & Impact Analysis Ability to Substantially Reduce a Significant Effect Shown by New ❑ Q Information but Declined by Proponent 2018 Dockweiler FEIR The Approved Project included the development of a roadway alignment and did not include the development of residential, commercial or industrial uses. As such no sanitary sewer connections were required. The 2018 FEIR determined the drainage system would be developed so that post development peak runoff discharge rates are equal to or less than predevelopment peak runoff rates, as required by the City of Santa Clarita and the Countywide MS4 Permit. Therefore, the Approved Project would not result in the construction of new stormwater drainage facilities or expansion of existing facilities. The Approved Project would not create a demand for potable water or for solid waste resources. Therefore, the 2018 FEIR determined impacts, with respect to utilities, would be less than significant. Proposed Project The Proposed Project would not alter the operations of local utility services, including water supply or treatment facilities. During construction temporary power would be used for construction equipment and debris would be taken to local landfills. While the Proposed Project would necessitate a limited extension of power and water to the site, these extensions would not require the relocation or expansion of existing facilities for water, wastewater treatment, stormwater drainage, electricity, natural gas, or telecommunications in the area as any use would be limited and minor. Operational activities would also result in some limited generation of solid waste during both construction and operation; however, all solid waste would be disposed of in accordance with local requirements. Further, as the Proposed Project is a relocation of an existing use, there would be no change in the amount of solid waste, water, and electricity generated at the regional level. Thus, the Proposed Project would have a less than significant impact on Utilities and Service Systems. Therefore, there would be no new or greater impacts than those identified in the 2018 Dockweiler FEIR. T. WILDFIRE As part of the 2018 State CEQA Guidelines updates, new Wildfire checklist questions were added that pertain to projects that are located in, or near, state responsibility areas, lands classified as very high fire hazard severity zones, and other conditions that could pose a hazard with respect to Wildfire. The potential for the Proposed Project to result in new or substantially more adverse significant impacts to wildfire was generally evaluated in relation to the 2018 Dockweiler FEIR hazards section and four questions recommended for consideration by the State CEQA Guidelines. Impact Sciences, Inc. 88 Placerita Yard Relocation Project 1250.020 Lyons AvenuelDockweiler Drive Extension Final EIR 2nd Addendum 3. Environmental Setting & Impact Analysis Do the Proposed Project require Subsequent or Supplemental CEQA Documentation with respect to being located in or near state responsibility areas or lands classified as very high fire hazard severity zones, and any of the following: (a) Substantially impairing an adopted emergency response plan or emergency evacuation plan? (b) Due to slope, prevailing winds, and other factors, exacerbating wildfire risks, and thereby expose project occupants to, pollutant concentrations from a wildfire or the uncontrolled spread of a wildfire? (c) Requiring the installation or maintenance of associated infrastructure (such as roads, fuel breaks, emergency water sources, power lines or other utilities) that may exacerbate fire risk or that may result in temporary or ongoing impacts to the environment? (d) Exposing people or structures to significant risks, including downslope or downstream flooding or landslides, as a result of runoff,post-fire slope instability, or drains a chan es? Yes No New Significant Environmental Effect Caused by a Change in the ❑ Q Project or Circumstances Substantial Increase in the Severity of a Previously Identified ❑ Q Significant Effect Caused by a Change in the Project or Circumstances New or Substantially More Severe Significant Impacts Shown by ❑ Q New Information Ability to Substantially Reduce a Significant Effect Shown by New ❑ .7 Information but Declined by Proponent 2018 Dockweiler EIR Impacts related to Hazards and Hazardous Materials were generalized in the 2018 Dockweiler FEIR and no separate Wildfire chapter was included within the 2018 Dockweiler FEIR. Accordingly, the 2018 Dockweiler FEIR did not provide an analysis or conclude the Approved Project's impacts related to wildland fires. Proposed Project The Norland Drive site is within a Fire Hazard Severity Zone in a State Responsibility Area (FHSZ in SRA) categorized as 'Very High'.38 As previously mentioned, other than minor repairs, no heavy vehicle maintenance, servicing, or refueling would take place as part of the Proposed Project. Therefore, no fuel storage tanks or vehicle maintenance bays that may require the storage and use of petroleum products and solvents will be included stored on site, making fire risks associated with the presence of petroleum -based fuels less than significant. Additionally, the Proposed Project would comply with the provisions of Title 32, Section 326, Activities in Wildfire Risk Areas, which includes Sections 326.7, Fire Protection Facilities Required.39 Section 326.7 establishes required fire protection facilities as well as conditions and/or limitations that are necessary to maintain reasonable fire safety, which includes but is not limited to the 38 Cal Fire, Fire Hazard Severity Zone Viewer, Available online at: hM2s://experience.arcgis.com/experience/03beab8511814e79a0e4eabf0d3e7247/, accessed August 7, 2024 39 County of Los Angeles, County of Los Angeles Code: Title 32, Section 326 —Activities in Wildfire Risk Areas.

Environmental Setting & Impact Analysis removal of dry grass and weeds from around buildings, along roadways, and automobile parking areas, providing adequate water supply, pumps, hydrants, and hoses, as well as including firebreaks as necessary to prevent a fire on the premises from spreading to adjacent brush or grass -covered areas.40 The Proposed Project would incorporate BMPs included in the LACDPW Construction Site BMPs Manual and adhere to the policies related to minimizing fire risks to existing and new land uses that were established in the Fire Hazard Planning and Technical Advisory published by the OPR.41,42 Compliance with regulations established in the County Code, the Fire Hazard Planning and Technical Advisory, and BMPs established in the LACDPW Construction BMPs Manual and regularly implemented by LACDPW, would ensure that implementation of the Proposed Project would not expose people or structures to wildfires. Therefore, impacts would be less than significant, and no new or greater impacts would occur. As the topography of the Norland Drive site is generally flat and there are no other nearby structures in the vicinity, the Proposed Project would not expose people or structures to significant downslope or downstream risks of flooding or landslides resulting from post -fire slope instability or drainage changes. Therefore, there would be no new or greater impacts than those identified in the 2018 Dockweiler FEIR. U. GROWTH INDUCING IMPACTS 2018 Dockweiler FEIR The 2018 Dockweiler FEIR determined that the Approved Project would not result in substantial growth inducing impacts. Proposed Project The Proposed Project would not induce growth in an area that is not already developed with infrastructure to accommodate any population growth. The Proposed Project would involve the relocation of an existing use and does not propose an expansion of use. Overall, as with the 2018 Dockweiler FEIR, the Proposed Project would not result in an increase in the population that could tax existing community service facilities or encourage or facilitate other activities 40 County of Los Angeles, County of Los Angeles Code: Title 32, Section 326.7 — Fire Protection Facilities Required.

Environmental Setting & Impact Analysis that could significantly affect the environment or the area, either individually or cumulatively. Thus, the Proposed Project would not result in significant growth -inducing impacts. The Norland Drive site is currently vacant with a minimally paved access road. However, the Proposed Project would not require extending or improving infrastructure in a manner that would facilitate off -site growth, as the maintenance yard would be served by existing adjacent streets for vehicles and the any utilities would only be for the County's use. There would be no change to existing staffing levels. Overall, the Proposed Project would not remove obstacles to population growth, result in an increase in the population that may tax existing community service facilities, or encourage or facilitate other activities that could significantly affect the environment or the area, either individually or cumulative. Thus, as discussed in the 2018 Dockweiler FEIR, the currently Proposed Project would not result in significant growth -inducing impacts. No new or greater impacts would occur. V. MANDATORY FINDINGS OF SIGNIFICANCE Mandatory Findings of Significance were evaluated with respect to the 2018 Dockweiler FEIR and three questions. (a) Does the Proposed Project require Subsequent or Supplemental CEQA Documentation with respect to the potential to substantially degrade the quality of the environment, substantially reduce the habitat of fish or wildlife species, cause a fish or wildlife population to drop below self-sustaining levels, threaten to eliminate a plant or animal community, substantially reduce the number or restrict the range of a rare or endangered plant or animal or eliminate important examples of the major periods of California history or prehistory? Yes No New Significant Environmental Effect Caused by a Change in the ❑ Q Project or Circumstances Substantial Increase in the Severity of a Previously Identified ❑ Q Significant Effect Caused by a Change in the Project or Circumstances New or Substantially More Severe Significant Impacts Shown by ❑ Q New Information Ability to Substantially Reduce a Significant Effect Shown by New ❑ Q Information but Declined by Proponent 2018 Dockweiler FEIR The 2018 Dockweiler FEIR concluded that the Approved Project would have significant impacts with respect to the issue areas identified below. • Air Quality — Construction: Emissions would exceed regional daily thresholds for VOCs and NOx and localized thresholds for NOx, PM2.5 and PM10 based on assumed equipment use and distance to sensitive receptors. Impact Sciences, Inc. 91 Placerita Yard Relocation Project 1250.020 Lyons AvenuelDockweiler Drive Extension Final EIR 2nd Addendum 3. Environmental Setting & Impact Analysis • Construction Noise: The 2018 FEIR indicates that construction noise levels would generate a noise level of 94.6 dBA, exceeding daytime noise standard levels at nearby sensitive receptors. Therefore, noise impacts from construction, while temporary, were identified as significant and unavoidable. The 2018 FEIR found, with mitigation, the Approved Project would not have the potential to substantially reduce the habitat of fish or wildlife species, cause a fish or wildlife population to drop below self- sustaining levels, threaten to eliminate a plant or animal community, reduce the number or restrict the range of a rare or endangered plant or animal or eliminate important examples of the major periods of California prehistory. Proposed Project The Proposed Project relates to each of the significant impacts identified in the 2018 Dockweiler FEIR as follows: • Air Quality — Construction: Construction activities associated with the Proposed Project would not result in peak daily emissions exceeding those analyzed in the 2018 FEIR. • Construction Noise: Noise and vibration impacts of construction would be within those evaluated in the 2018 Dockweiler FEIR. No additional mitigation would be required and there would be no new or greater impacts than those identified in the 2018 FEIR. The significant impacts identified in the 2018 Dockweiler FEIR have the potential to degrade the quality of the environment. No additional mitigation has been identified and there would be no new or greater impacts than those identified in the certified 2018 FEIR with respect to these issue areas. The Proposed Project would not increase impacts compared to those analyzed in the 2018 FEIR and therefore similarly would not substantially impact the habitat of fish or wildlife species, cause a fish or wildlife population to drop below self-sustaining levels, threaten to eliminate a plant or animal community, reduce the number or restrict the range of a rare or endangered plant or animal or eliminate important examples of the major periods of California prehistory. Impact Sciences, Inc. 92 Placerita Yard Relocation Project 1250.020 Lyons AvenuelDockweiler Drive Extension Final EIR 2nd Addendum 3. Environmental Setting & Impact Analysis (b) Does the Proposed Project require Subsequent or Supplemental CEQA Documentation with respect to impacts, which are individually limited, but cumulatively considerable? ("Cumulatively considerable "means that the incremental effects of an individual project are considerable when viewed in connection with the effects of past projects, the effects of other current projects, and the effects of probable future ro'ects.) Yes No New Significant Environmental Effect Caused by a Change in the ❑ Q Project or Circumstances Substantial Increase in the Severity of a Previously Identified ❑ Q Significant Effect Caused by a Change in the Project or Circumstances New or Substantially More Severe Significant Impacts Shown by ❑ Q New Information Ability to Substantially Reduce a Significant Effect Shown by New ❑ Q Information but Declined by Proponent 2018 Dockweiler FOR Other than the significant impacts identified above, the 2018 FEIR did not identify any other impacts that would be individually limited, but cumulatively considerable. Proposed Project All impacts associated with the Proposed Project would be within those analyzed in the 2018 Dockweiler FEIR and therefore would not result in individually limited impacts that could be cumulatively considerable. (c) Does the Proposed Project require Subsequent or Supplemental CEQA Documentation with respect to environmental effects, which cause substantial adverse effects on human beings, either directly or indirectly? Yes No New Significant Environmental Effect Caused by a Change in the ❑ Q Project or Circumstances Substantial Increase in the Severity of a Previously Identified ❑ Q Significant Effect Caused by a Change in the Project or Circumstances New or Substantially More Severe Significant Impacts Shown by ❑ Q New Information Ability to Substantially Reduce a Significant Effect Shown by New ❑ Q Information but Declined by Proponent 2018 Dockweiler FEIR The two significant impacts identified above (air quality and noise) that were analyzed in the 2018 FEIR would have the potential to cause substantial adverse effects on human beings, either directly or indirectly. Impact Sciences, Inc. 93 Placerita Yard Relocation Project 1250.020 Lyons AvenuelDockweiler Drive Extension Final EIR 2nd Addendum 3. Environmental Setting & Impact Analysis Proposed Project The Proposed Project would not require additional mitigation or result in new or greater impacts than those identified in the 2018 Dockweiler FEIR with respect to adverse effects to human beings. W. CONCLUSION The Proposed Project is described in Section 2 of this Addendum and would be within the assumptions analyzed in the 2018 Dockweiler FEIR. The Proposed Project has been reviewed by the County of Los Angeles in light of Sections 15162 and 15163 of the State CEQA Guidelines. As the CEQA Lead Agency, the County of Los Angeles has determined, based on the analysis presented herein, that none of the conditions (identified in Section 1) apply which would require preparation of a subsequent or supplemental EIR and that an Addendum to the certified Lyons Avenue/Dockweiler Drive Extension Final EIR is the appropriate environmental documentation under CEQA for the Proposed Project. Section 3 discusses issue -by -issue how the impacts anticipated for the Proposed Project would be within those previously identified in the 2018 Dockweiler FEIR. The MMRP adopted with the 2018 Dockweiler FEIR would apply as appropriate to the Proposed Project to ensure that all impacts are reduced as necessary and feasible. Further, the Proposed Project is consistent with the 2011 OVOV FEIR. As discussed throughout this Addendum, the Proposed Project would result in environmental impacts within those analyzed for Lyons Avenue/Dockweiler Drive Extension Project for every issue with implementation of applicable mitigation measures from the 2018 Dockweiler FEIR.

The Placerita Maintenance Yard Project (Project) proposes to construct on 1.72 acres of vacant land between Highway 14 and the Santa Clara River. This Assessment analyzes the potential for special status endangered, threatened, and sensitive species and their habitats to occur within the proposed project limits and an appropriate buffer (Biological Survey Area). 1.1 Summary of Findings The Biological Survey Area includes potential habitat for no special status plant species and four special status wildlife species. These include one federally threatened species: California Gnatcatcher (Polioptila californica californica), one federally endangered species: Arroyo Toad (Anaxyrus californicus), one federally proposed as threatened species: Western Spade Foot (Spec hammondii), and one California candidate endangered species: Crotch Bumble Bee (Bombus crotchii). The Santa Clara River is found immediately south of the Project Area and approximately 35 feet south of Norland Drive. Some erosional undercutting leading directly to the Santa Ana River was found along Norland Drive. Additionally, the City's water discharge was identified at the far east boundary of the Project Site. 1.2 Project Location The proposed Project is approximately 1.72 acres of vacant land and 0.87 acres of road along Norland Drive, south of Highway 14 and north of the Santa Clara River in Santa Clarita, Los Angeles County, CA. The site is generally located in Section 13, Township 4 North, Range 15 West San Bernardino Meridian of the U.S. Geological Survey's (USGS) 7.5 minute Mint Canyon quadrangle (Figure 1). 1.3 Project Description The project proposes to construct a maintenance yard on approximately 1.72 acres of vacant land at the end of Norland Drive. Additionally, the client has proposed to expand the road along Norland Drive by 12 feet north and south. The vacant lot proposed for the maintenance yard is devoid of vegetation for approximately 1.0 acre, with the remaining 0.72 acre consisting of mostly disturbed vegetation. Vegetation along Norland Drive is made up of scrubland and disturbed vegetation. Immediately south of the Project site is the Santa Clara River, containing a sparsely vegetated stream bed with riparian scrub species. North and west of the Project boundaries is developed land with roads and residential buildings. The Project will involve vegetation removal and leveling of the land while avoiding impacts to the Santa Clara River. Travel to and from the site will be on existing, maintained roads. The staging areas will occur onsite or within already developed areas adjacent to the Project Site. 1.4 Definitions The following definitions for areas are illustrated in Figure 2 and will be followed throughout this report: • Project site: The Project site is defined as the 1.72 acres being analyzed for Project entitlements. • Biological Study Area: The Biological Study Area is defined as the Project site and a 500-foot buffer (approximately 80.37 acres). This is the area within which biological resources were fully analyzed. Providing Environmental Solutions for a Developing World 1 Biological Resources Assessment Placerita Maintenance Yard Project 204'7-24 May 2024 • Regional Study Area: The Regional Study Area is defined as the Project site and a 3-mile buffer. The Regional Study Area was used as the basis for determining special -status biological resource records for consideration in this report.

FESA is jointly implemented by the United States Fish and Wildlife Service (USFWS) and the National Marine Fisheries Service (NMFS, addressing marine resources only). FESA protects species using the following status designations: • A federally endangered species is a species of invertebrate, plant, or wildlife formally listed by the USFWS under FESA as facing extinction throughout all or a significant portion of its geographic range. • A federally threatened species is one formally listed by the USFWS as likely to become endangered within the foreseeable future throughout all or a significant portion of its range. • A proposed threatened or endangered species is one officially proposed by the USFWS for addition to the federal threatened or endangered species list. • Candidate species are "plants and animals for which the USFWS has sufficient information on their biological status and threats to propose them as endangered or threatened under FESA, but for which development of a proposed listing regulation is precluded by other higher priority listing activities" (USFWS 2017). "Take" of a federally endangered or threatened species or its habitat is prohibited by federal law without a special permit. The term "take," under FESA, means to harass, harm, pursue, hunt, shoot, wound, kill, trap, capture, or collect, or to attempt to engage in such conduct. "Harm" is defined by the USFWS to encompass "an act which actually kills or injures wildlife. Such an act may include significant habitat modification or degradation where it actually kills or injures wildlife by significantly impairing essential behavioral patterns, including breeding, feeding or sheltering" (50 CFR § 17.3). Section 10(a)(1)(13) of the FESA allows for take of a threatened or endangered species incidental to development activities once a Habitat Conservation Plan (HCP) has been prepared to the satisfaction of the USFWS and a Section 10(a) incidental take permit has been issued to an applicant. For federal projects (including those involving federal funding), Section 7 of the FESA allows for consultation between the affected agency and the USFWS to determine what measures may be necessary to compensate for the incidental take of a listed species. A federal project is any project that is proposed by a federal agency or is at least partially funded or authorized by a federal agency. Additionally, if the listed species or its habitat occurs in a portion of the project subject to federal jurisdiction (such as waters of the United States by the United States Army Corps of Engineers [USACE] under Section 404 of the Clean Water Act [CWA]), then consultation under Section 7 of the FESA is usually permissible and may be required. FESA also requires the USFWS to consider whether there are areas of habitat essential to conservation for each listed species. Critical habitat designations protect these areas, including habitat that is currently unoccupied but may be essential to the recovery of a species. An area is designated as critical habitat after the USFWS Providing Environmental Solutions for a Developing World Biological Resources Assessment Placerita Maintenance Yard Project 2047-24 May 2024 publishes a proposed federal regulation in the Federal Register and then receives and considers public comments on the proposal. The final boundaries of critical habitat are officially designated when published in the Federal Register. 2.1.2 Migratory Bird Treaty Act The Migratory Bird Treaty Act of 1918 (MBTA) is a federal law governing the taking, killing, possession, transportation, and importation of various birds, their eggs, parts, and nests. The take of any number of a bird species listed as protected on any one of four treaty lists is governed by the MBTA's regulation of taking migratory birds for educational, scientific, and recreational purposes and requiring harvest to be limited to levels that prevent over utilization. The MBTA also prohibits taking, possession, import, export, transport, selling, purchase, barter, or offering for sale, purchase or barter, certain bird species, their eggs, parts, and nests, except as authorized under a valid permit (50 CFR 21.11). 2.1.3 Clean Water Act of the United States The regulatory setting with regards to aquatic resources is framed by current enabling legislation and case law. Under Section 404 of the CWA, the USACE regulates the discharge of dredged and fill materials into "waters of the U.S." Jurisdictional waters of the U.S. include "territorial seas, and waters which are currently used, or were used in the past, or may be susceptible to use in interstate or foreign commerce, including waters which are subject to the ebb and flow of the tide; tributaries; lakes and ponds, and impoundments of jurisdictional waters; and adjacent wetlands" (33 CFR § 328.3). Certain waters of the U.S. are considered "special aquatic sites" because they are generally recognized as having ecological value; such sites include sanctuaries and refuges, wetlands, mudflats, vegetated shallows, and riffle and pool complexes (40 CFR § 230). Special aquatic sites are defined by the U.S. Environmental Protection Agency (USEPA) and may be afforded additional consideration in a project's permit process. The USACE also regulates navigable waters under Section 10 of the Rivers and Harbors Act of 1899. Navigable waters are defined as "... those waters of the U.S. that... are presently used, or have been used in the past, or may be susceptible to use to transport interstate or foreign commerce" (33 CFR § 322.2). Projects that place fill in jurisdictional wetlands and non -wetland waters of the U.S. require a permit from the USACE under Section 404 of the CWA. The USACE issues nationwide permits for specific types of activities with minimal individual or cumulative adverse environmental impacts. Individual permits are required for large and/or complex projects or projects that exceed the impact threshold for nationwide permits. Recent federal rulemaking has modified how the USACE defines certain waters of the U.S. The most pertinent rules are summarized below. The regulatory setting is framed by current enabling legislation and case law. As of August 29, 2023, the USEPA and USACE amended the definition for "waters of the United States" per the Supreme Court Sackett v. USEPA decision. The previous overarching regulatory decision — the 2023 Rule — has had three distinct components modified. Under the Sackett v. USEPA. decision, waters are no longer jurisdictional under the CWA due to the "significant nexus standard." 2. Under the Sackett v. USEPA. decision, wetlands are not defined as "adjacent" or jurisdictional under the CWA solely because they are "bordering, contiguous, or neighboring or separated" from other "waters of the United States" by man-made dikes or barriers, natural river berms, beach dunes. Providing Environmental Solutions for a Developing World Biological Resources Assessment Placerita Maintenance Yard Project 2047-24 May 2024 3. Under the Sackett v. USEPA decision, the USEPA and USACE are removing "interstate wetlands" from the 2023 Rule. The Court ruled that the use of the term "waters" referred to "open waters" and not wetlands so determined that a wetland is not jurisdictional due to singularly being interstate. The remainder of the 2023 Rule will continue to regulate the interpretation of defining "waters of the United States." These recent regulatory modifications require interpretation by USACE regulatory staff who will make jurisdictional determinations for any mapped aquatic features within the Project site. In a previous determination the USEPA published a revised definition of "waters of the United States" on December 7, 2021, in response to President Biden's Executive Order 13990 (86 Federal Register 7037) and after Pascua Yaqui Tribe v. EPA in which the U.S. District Court of the District of Arizona "vacated and remanded" the Navigable Waters Protection Rule (86 Federal Register 69372). The proposed revision was published in the Federal Register on January 18, 2023, and took effect on March 20, 2023. Due to litigation, the agencies interpreted "waters of the United States" consistent with pre-2015 regulations and the Supreme Court cases of Rapanos v. United States and Carabell v. United States (USEPA 2008), meaning the USACE asserted jurisdiction over traditional navigable waters (TNW) and the following types of features determined to have "significant nexus" to a TNW: 1. wetlands adjacent to TNWs 2. non -navigable tributaries of TNWs that are relatively permanent where the tributaries typically flow year-round or have continuous flow at least seasonally 3. wetlands that directly abut non -navigable tributaries of TNWs However, the Sackett decision to remove the significant nexus standard and adjacency criteria with regards to what constitutes a jurisdictional wetland substantially redefines the pre-2015 regulations. 2.2 State of California 2.2.1 California Environmental Quality Act The California Environmental Quality Act (CEQA) is a public disclosure process codified by California Public Resources Code 21000, requiring decision -makers to analyze the environmental impacts of a project, disclose those impacts to the public, and mitigate environmental impacts to the extent feasible. The state or local lead agency provides an evaluation of project effects on biological resources; determining the significance of those effects is guided by Appendix G of the CEQA Guidelines (AEP 2023). These evaluations must consider direct effects on a biological resource within the project site itself, indirect effects on adjacent resources, and cumulative effects within a larger area or region. Effects can be locally important but not significant according to CEQA if they would not substantially affect the regional population of the biological resource. Significant adverse impacts on biological resources would include the following: • Substantial adverse effects on any species identified as candidate, sensitive, or special status in local or regional plans, policies, or regulations or by the California Department of Fish and Wildlife (CDFW) or the USFWS (these effects could be either direct or via habitat modification); • Substantial adverse impacts to species designated by the CDFW as Species of Special Concern (SSC); Providing Environmental Solutions for a Developing World Biological Resources Assessment Placerita Maintenance Yard Project 2047-24 May 2024 • Substantial adverse effects on riparian habitat or other sensitive habitat identified in local or regional plans, policies, or regulations or by CDFW and USFWS; • Substantial adverse effects on federally protected wetlands defined under Section 404 of the CWA (these effects include direct removal, filling, or hydrologic interruption of marshes, vernal pools, coastal wetlands, or other wetland types); • Substantial interference with movements of native resident or migratory fish or wildlife species population, or with use of native wildlife nursery sites; • Conflicts with local policies or ordinances protecting biological resources (e.g., tree preservation policies); and; • Conflict with provisions of an adopted HCP, Natural Community Conservation Plan (NCCP), or another approved local, regional, or state habitat conservation plan. 2.2.2 California Endangered Species Act The California Endangered Species Act (CESA) prohibits the take of state -listed threatened and endangered species. Under CESA, state agencies are required to consult with CDFW when preparing CEQA documents. Under CESA, CDFW is responsible for maintaining a list of rare, threatened, and endangered species designated under state law (California Fish and Game Code [CFGC] § 2070-2079). CDFW also maintains lists of candidate species, SSC, and fully -protected species. Candidate species are those taxa that have been formally recognized by the CDFW and are under review for addition to the state threatened and endangered list. Species of special concern are those taxa that are considered sensitive, and this list serves as a "watch list." The CDFW can authorize "take" if an incidental take permit is issued by the Secretary of the Interior or of Commerce in compliance with FESA, or if the director of the CDFW issues a permit under Section 2080 in those cases where it is demonstrated that the impacts are minimized and mitigated. 2.2.3 California Fish and Game Code Section 1600 et seq. — Lake and Streambed Alteration Agreement. Section 1600 provides provisions for protecting riparian systems, including the bed, banks, and riparian habitat of lakes, seasonal and perennial streams, and rivers. This section requires an applicant to notify CDFW and obtain a Lake and Streambed Alteration Agreement (LSAA) if their project would divert or obstruct the natural flow of any river, stream, or lake; change the bed, channel, or bank of any river, stream, or lake; use material from any river, stream, or lake; or deposit or dispose of material into any river, stream, or lake. Section 2050 et seq. — California Endangered Species Act. CESA establishes the policy of the state to conserve, protect, restore, and enhance threatened or endangered species and their habitats. CESA is administered by CDFW and prohibits the take of any species that the California Fish and Game Commission determines to be a threatened or endangered species. CESA also mandates that "state agencies should not approve projects as proposed which would jeopardize the continued existence of any endangered species or threatened species" if reasonable and prudent alternatives are available that would avoid jeopardy. CDFW administers CESA and authorizes take through CFGC 2081 Incidental Take Permits or through Section 2080.1. (For species also listed under FESA, consistency determination is with a USFWS Biological Opinion). Providing Environmental Solutions for a Developing World Biological Resources Assessment Placerita Maintenance Yard Project 2047-24 May 2024 Section 3511 —Fully Protected Species. The legislature of the State of California designated certain species as "fully protected" prior to the creation of CESA. Section 3511 states that "fully protected" birds or parts thereof may not be taken or possessed at any time. Lists of fully protected species were initially developed to provide protection to those animals that were rare or faced possible extinction and included fish, mammals, amphibians and reptiles, and birds. Most fully protected species have since been listed as threatened or endangered under CESA and/or FESA. Sections 3503, 3503.5, 3505, 3513 — Birds. These CFGC sections protect all birds, including birds of prey and all nongame birds, as well as their eggs and nests, for species that are not already listed as fully protected and that occur naturally within the state. Sections 3503 and 3503.5 of the CFGC stipulate the following regarding eggs and nests: Section 3503 states that it is unlawful to take, possess, or needlessly destroy the nest or eggs of any bird, except as otherwise provided by CFGC or any regulation made pursuant thereto; and Section 3503.5 states that is it unlawful to take, possess, or destroy any birds in the orders Falconiformes or Strigiformes (birds -of - prey) or to take, possess, or destroy the nest or eggs of any such bird except as otherwise provided by CFGC or any regulation adopted pursuant thereto. Section 3513 states that it is unlawful to take or possess any migratory nongame bird as designated in the MBTA or any part of such migratory nongame bird except as provided by rules and regulations adopted by the Secretary of the Interior under provisions of the MBTA. 2.2.4 California Native Plant Protection Act The California Native Plant Protection Act of 1977 (GFGC § 1900-1913) affords the CDFW Commission the authority to designate native plants as endangered or rare and protect them from "take." The California Native Plant Society (CNPS) maintains a list of sensitive plant species native to California and assigns each a rank in the California Rare Plant Rank (CRPR) system defined below: • List 1A: Plants presumed extirpated in California and either rare or extinct elsewhere; • List 113: Plants are rare, threatened, or endangered in California and elsewhere; • List 2A: Plants presumed extirpated in California, but more common elsewhere; • List 213: Plant are rare, threatened, or endangered in California, but more common elsewhere; • List 3: Plants about which more information is needed (on a review list); • List 4: Plants of limited distribution (on a watch list). This list is further defined as described below: • 0.1: Seriously threatened in California, meaning there is a high degree (over 80% of occurrences) and immediacy of threat; • 0.2: Moderately threatened in California, meaning there is a moderate degree (20-80% of occurrences) and immediacy of threat; • 0.3: Not very threatened in California, meaning there is a low degree (less than 20% of occurrences) and immediacy of threat. Providing Environmental Solutions for a Developing World Biological Resources Assessment Placerita Maintenance Yard Project 2047-24 May 2024 All plants on Lists 1 and 2 meet the standards for state listing under the CEQA Guidelines (14 CCR § 15380). CNPS recommends that plants on Lists 3 and 4 be evaluated for consideration under CEQA. 2.2.5 Porter -Cologne Water Quality Control Act The Porter -Cologne Water Quality Control Act of 1969 established the State Water Resources Control Board (SWRCB) and the nine Regional Water Quality Control Boards (RWQCB), collectively referred to as the Water Boards, and authorized them to provide oversight for water rights and water quality. It uses the National Pollutant Discharge Elimination System (NPDES) to monitor point source discharges into the waters of the State to prevent water quality degradation. It also protects wetlands, surface waters, and groundwater from both point and nonpoint sources of pollution. 2.2.6 State Wetland Definition and Procedures The SWRCB adopted the State Wetland Definition and Procedures for Discharges or Fill Material to Waters of the State in 2019 and completed revisions to this set of procedures in 2021 (SWRCB 2021). Four major elements are included in these procedures as described below, in addition to procedures for the submittal, review and approval of CWA Section 401 permits not described in this report. 1. Wetland definition: An area is wetland if, under normal circumstances, (1) the area has continuous or recurrent saturation of the upper substrate caused by groundwater, or shallow surface water, or both; (2) the duration such saturation is sufficient to cause anaerobic conditions in the upper substrate; and 3) the area's vegetation is dominated by hydrophytes or the area lacks vegetation. 2. Framework for determining waters of the state: Waters of the state are broadly defined by the Porter -Cologne Water Quality Control Act as "any surface water or groundwater, including saline waters, within the boundaries of the state." The 2021 procedures expand upon this definition to clearly include natural wetlands, wetlands created by modification of a surface water of the state, and artificial wetlands meeting specific criteria. The criteria for an artificial wetland include wetlands created for agency -approved compensatory mitigation; those identified in a water quality control plan; and those greater than or equal to one acre in size unless they are constructed and maintained for wastewater treatment or disposal, sediment settling, stormwater permitting program pollutant or runoff management, surface water treatment, agricultural crop irrigation or stock watering, fire suppression, industrial processing and cooling, active surface mining, log storage, recycled water management, maximizing groundwater recharge, or rice paddies. 3. Wetland delineation procedures: USACE-defined procedures for aquatic resources delineation (USACE 1987; USACE 2008 used to assess the presence or absence of hydrophytic vegetation, hydric soils, and wetland hydrology are required by the SWRCB to delineate waters of the state, with one modification being that "the lack of vegetation does not preclude the determination of such an area that meets the definition of wetland."

This plan functions to act as a more focused component of the Los Angeles County and City of Santa Clarita General Plans. Open space preservation, trail planning, hillside development, and historic preservation for the Santa Clarita Valley are specifically outlined. The plan was developed with the idea that there should be a unified effort to adequately distribute land use to provide long lasting infrastructure and conserve natural resources. The plan mentions its commitment to avoiding and minimizing impacts to sensitive species and their habitat during development activities. An Environmental Impact Report was prepared for this document to address concerns of the areas biological, cultural, water, and open space resources. This includes protecting critical habitat for the sensitive species known to occur in the region. 2.3.2 City of Santa Clarita General Plan The City of Santa Clarita General Plan is a set of goals, objectives, policies, implementation measures, and maps that inform land use decisions to provide its citizens with acceptable infrastructure. The General Plan contains numerous goals, policies, and strategies to protect and/or preserve its biological resources. The Conservation and Open Space Element of the General Plan defines the resource conservation issues relevant to the city. This section of the General Plan defines Significant Ecological Areas within the city. It details the habitat type present, the sensitive communities and species known to inhabit the areas and the impacts they have faced thus far. Guidelines to reduce and minimize impacts to these sensitive resources are outlined in this section. If impacts have a substantial adverse effect on special -status species, mitigation measures include supporting State and Federal policies for preservation and enhancement of riparian and wetland habitats by incorporating, as applicable, standards published by the California Department of Fish and Wildlife and the U.S. Fish and Wildlife Service into site -specific development proposals. 3 Methods This Assessment is informed by data from a desktop analysis of the literature and numerous resource databases, as well as field surveys. The methods used to complete these surveys and desktop analyses are described below. 3.1 Desktop Review Prior to conducting field surveys, Bargas conducted an initial review of literature and data sources to characterize biological conditions and to compile records of sensitive biological resources that could potentially occur in the Biological Study Area. The methods used for this analysis are described below. Providing Environmental Solutions for a Developing World 11 Biological Resources Assessment Placerita Maintenance Yard Project 2047-24 May 2024 3.1.1 Biological Setting The biological setting includes terrain, hydrology, soils, land uses, and other features that support or inhibit biological resources in an area. In order to better understand the biological setting of the project, the following resources were reviewed in detail: • USFWS's National Wetlands Inventory to determine if surface waters and wetlands have been mapped on or adjacent to the Biological Study Area. • U.S. Department of Agriculture National Resource Conservation Service Web Soil Survey to map and describe soil(s) within the Biological Study Area. • Google Earth Pro aerial map images of the Biological Study Area, including historical aerial images. 3.1.2 Special Status Species & Habitats It is important to create a well-defined list of habitats and species that could reasonably be expected to occur on the Project site in order to analyze potential Project effects on biological resources effectively. The following describes how the list of potentially occurring special status biological resources was assembled. 3.1.2.1 Data Sources Species and habitat occurrences were queried from the following resources: • USFWS's Information for Planning and Consultation portal (IPaC) for a list of federally listed species and designated critical habitat recommended for impact analysis consideration, based on an upload of the Biological Study Area limits. • CDFW's California Natural Diversity Database (CNDDB) for special status species and habitat records within the Regional Study Area. • CNPS's Inventory of Rare and Endangered Plants for a list of special status plant species occurrences within the USGS 7.5-minute quadrangles that overlap the Regional Study Area. 3.1.2.2 Special Status Designations Considered A variety of agencies and respected non-profit organizations assess the conservation status of plant and wildlife species; however, not all are applicable to this Assessment. The following special status designations were considered when determining special status species to be discussed in this Assessment: • Federal Status: Species listed as Endangered (FE) or Threatened (FT), as well as species Proposed as Endangered (FIRE), Proposed as Threatened (FPT), Proposed for Delisting (FPD), and Candidates (FC) for listing under the FESA. • California Status: Species listed as Endangered (CE) or Threatened (CT), as well as species that are Candidates for Endangered (CCE) status, Threatened (CCT) status, or Delisting (CCD) under the California Endangered Species Act. Also considered are species listed as Fully Protected (FP) and Species of Special Concern (SSC). • CNPS Status: All California Rare Plant Ranks (CRPR) maintained by the CNPS Inventory of Rare and Endangered Plants. • Vegetation Communities: All vegetation communities mapped by the CNDDB. Providing Environmental Solutions for a Developing World 12 Biological Resources Assessment Placerita Maintenance Yard Project 2047-24 May 2024 3.1.3 Occurrence Potential Following the desktop review, field surveys, and habitat analyses, Bargas assessed the potential for the occurrence of special status species in the Biological Study Area. Biological conditions (vegetation communities, wildlife habitats, disturbances, etc.) and the habitat and life cycle requirements of special status species identified for analysis in the desktop review were considered. "Recent" occurrences are defined as observed within the past 30 years. Based on these considerations, species were assigned to the following categories: • Present: Species is known to occur in Biological Study Area based on recent surveys, CNDDB (within 30 years), or other records. • High: Species with known recent recorded occurrences/populations near the Biological Study Area and highly suitable habitat occurs within the Biological Study Area. Highly suitable habitat includes all necessary elements to support the species (e.g., elevation, hydrology, soils, cover, habitat type, food resources). • Moderate. Species with known recent recorded occurrences/populations near the Biological Study Area; however, habitat within the Biological Study Area has been moderately disturbed, fragmented, or is small in extent. Moderately suitable habitat includes several elements to support the species (e.g., elevation, hydrology, soils, cover, habitat type, food resources). Furthermore, moderately suitable habitat may also be located at the edge of the species' range, or there are no reported occurrences nearby. • Low. Species with few known recent recorded occurrences/populations near the Biological Study Area and habitat within the Biological Study Area is highly disturbed or extremely limited. A low potential is assigned to annual or perennial plant species that may have been detectable during a focused survey in the appropriate blooming period but was not found; however, small populations or scattered individuals are still considered to have a low potential to occur. Additionally, species for which poor -quality habitat may support the species within the Biological Study Area, but the reported extant range is far outside the Biological Study Area and/or any species observations would anticipate being migratory (i.e., not likely to reproduce within the Biological Study Area). Presumed Absent/No Potential. Focused surveys were conducted, and the species was not detected, or the species was found in the desktop review but suitable habitat (soil, vegetation, elevational range) was not found in the Biological Resource Assessment (BRA), or the BSA is not within the known geographic range of the species. The potential for bird species were further distinguished into those that may: 1) nest within or near the Biological Study Area; 2) forage within or near the Biological Study Area; and/or 3) occur on or near the Biological Study Area only as transients during migratory flights or other dispersal events. 3.2 Field Surveys A field assessment was conducted for the Biological Survey Area on May 3, 2024. Meandering transects were conducted on foot throughout the entire Biological Survey Area. Habitat types were documented, and plant and wildlife species were recorded. Habitats that were determined to be potential habitat for a special status species were further assessed for suitability. Providing Environmental Solutions for a Developing World 13 Biological Resources Assessment Placerita Maintenance Yard Project 204'7-24 May 2024 3.3 Taxonomy and Nomenclature Every effort was made to use naming standards that are recognized by the scientific community, with the understanding that —for many wildlife groups —scientists may not always agree on a standard source. Because of this, some common names used in this report may not be the same as those used by the underlying data sources for species records. Bargas maintains a yearly -updated reference species list which uses the following taxonomic sources: • Birds — American Ornithological Society Checklist and Supplements (AOS 1998). • Mammals — The reference list in the CDFW's California Wildlife Habitats Relationships Database (CDFW 2014), with updates based on the American Society of Mammologists Mammal Diversity Database (2020). • Reptiles and Amphibians — The technical website californiaherps.com, which is regularly updated based on the latest taxonomic literature. • Fish — Common and Scientific Names of Fishes from the United States, Canada, and Mexico, 7th edition (AFS 2013) • Invertebrates — No naming standard was identified that was current and applicable to freshwater and terrestrial invertebrates. Names used by the underlying data sources when a species was first identified were retained. • Plants — The Jepson eFlora database (Jepson Flora Project 2021) Providing Environmental Solutions for a Developing World 14 Biological Resources Assessment Placerita Maintenance Yard Project 2047-24 May 2024 4 Results This section discusses in detail what is known about biological resources in the Biological Study Area based on information from field surveys, nine CNDDB records, two CNPS records, seventeen IPaC records, and no critical habitat determinations in the Regional Study Area. A list of plant and wildlife species observed within the Biological Survey Area is included in Appendix A. 4.1 Biological Setting The Project site is comprised of an existing vacant lot adjacent to the Santa Clara River. The northern and western boundaries of the Project site are developed while riparian scrub habitat can be found on the southern and eastern boundaries of the Project Site. The western section of the vacant lot is primarily unvegetated, flat, rocky terrain, while the eastern section is made of softer sandy loam soils with scrub and forb species. The previously developed land is primarily dominated by exotic and disturbed plant species. The road expansion Project area along Norland Drive, is densely vegetated with scrub species on sandy loam soils. Riparian scrub habitat can be found immediately south in the Santa Clara River. The Project site is terraced with the streambed located approximately four feet below the Project site. Plant species observed within the Project site include California Sagebrush (Artemisia californica), Common Sagebrush (Artemisia tridentate), Maltese Star Thistle (Centaurea melitensis), and Short -podded Mustard (Hirschfeldia). A City water discharge site was observed at the far eastern portion of the vacant lot but is located outside of the Project boundary. Taller tree and shrub species were found at the City water discharge site, including Arroyo Willow (Salix lasiolepsis) and Mexican FanpaIm (Washingtonia robusta). The Project site is owned by the City and access is limited by a gate at the far western end of Norland Drive. The Project site also contains barbed wire fencing along the northern border to prevent access to the public. The Santa Clara River and Scrub habitat along Norland Drive provides suitable habitat for several species. Birds were seen utilizing larger shrubs and trees outside of the Project boundaries but were only seen foraging within the Project site. Nesting habitat within the Project site is marginal. Scrub and shrub species are less than three feet in height and plant cover is minimal even in the more densely vegetated areas. No amphibian species were detected; however, the streambed provides suitable habitat for amphibians during heavy rain events and for burrowing species during the dry seasons. Species observed within the BSA include Western Fence Lizard (Sceloporus occidentalis), Audubon's Cottontail (Sylvilagus adubonii), Ash -throated Flycatcher (Myiarchus cinerascens), and California Scrub -Jay (Aphelocoma californica). A full list of plant and animal species observed within the BSA is included as Appendix A. Providing Environmental Solutions for a Developing World 15 Biological Resources Assessment Placerita Maintenance Yard Project 204'7-24 May 2024 4.2 Soils The soils identified in the BSA include Hanford sandy loam, Riverwash, Sandy Alluvial land, and Saugus loam. Prior to development this area was a part of the Santa Clara River. All areas north of the Project Site have been heavily developed. A map of soils within the Project site is shown in Figure 3. 4.3 Habitats Three habitat types were mapped within the Biological Study Area. These include Urban Developed, Riparian Scrub, and Disturbed as described below. The habitats mapped within the Biological Study Area are shown in Figure 4 and photographs are included in Appendix B.

Vegetation is sparse along the western half of the vacant lot with exotic species being found on the eastern portion of the Project site and along Norland Drive. Reptile species were observed basking on rocks and hiding under vegetation cover. Bird species were observed perching on electrical lines, utility poles, and fencing. This area had been previously flattened and graded with a paved road spanning both sides of the Project Site. 4.3.2 Riparian Scrub South of the Project site is the Santa Clara River with a sparsely vegetated stream bed. This area is dry for most of the year and is largely undisturbed. Species of Saltbush (Atriplex ssp.), California Sagebrush (Artemesia Californica), Common Sagebrush (Artemesia tridentada), and Tamarisk (Tamarix ssp.) were observed. This area was utilized by a number of taxa; Audubon's Cottontail (Sylvilagus audubonii), Ash -throated Flycatcher (Myiarchus cinerascens), and Lazuli Bunting (Passerina amoena) were observed. This land may be used by amphibian species during the wet season and by burrowing species during the dry season. No amphibian species were detected during the survey. 4.3.3 Urban Developed A majority of the area north and west of the Project site is urban developed landscape. Highway 14 is located immediately north of the Project site and residential homes are found adjacent to the highway. At the access point west of Norland Drive there are storage units used by the public. Santa Clarita is largely developed with residential homes, businesses, and open spaces found throughout the Santa Clara Valley. These developed areas are made up of ornamental vegetation that do not provide suitable habitat for wildlife. 4.4 Aquatic Resources No aquatic resources were observed within the Project site. A formal ACOE protocol -level wetland delineation was not conducted within the total 1.72 acre Project site, but no signatures of wetlands were present. The site is relatively flat, but the Santa Clara River and Santa Clarita City discharge channel were found immediately outside the Project site boundary. The City discharge channel is to be fenced off to avoid impacts to the vegetation. Erosional undercutting that leads directly to the Santa Clara River was observed along Norland Drive. Road expansion may impact the streambed where the channel meets the road lens. The road expansion may impact the river if debris and asphalt enter the channel. 4.5 Special Status Species 4.5.1 Special Status Plants The desktop review determined that nine plant taxa with special status had been documented as occurring within the Regional Study Area. All nine species were determined to have no potential for occurrence.

Of these, eight species were determined to have No potential to occur due to lack of required habitat components. Four species were determined to have Moderate potential to occur, and three species was determined to have Low potential to occur. These taxa and their occurrence potential within the Study Area are summarized below.

Providing Environmental Solutions for a Developing World 21 Biological Resources Assessment Placerita Maintenance Yard Project 2047-24 May 2024 4.5.2.3 Taxa With Moderate Potential for Occurrence Three special status wildlife taxa were determined to have Moderate potential for occurrence in the Biological Study Area. 1. California Gnatcatcher prefer to inhabit Sagescrub communities with nesting habitat in the form of scrub species taller that three feet in height. Suitable habitat is found within the Project site as Sage (Salvia ssp.) were detected but at low densities. No individuals were detected during the survey. 2. Arroyo Toad require slow moving, narrow, and shallow aquatic habitat with nearby upland areas for burrowing. The Santa Clara River provides suitable habitat for this species especially during rain events. 3. Western Spadefoot inhabit areas where they can burrow to hide against predators and have water sources for breeding. The western spadefoot becomes active for a short period between October and March. 4.5.2.4 Taxa With Low Potential for Occurrence Four special status wildlife taxa from desktop analysis and pedestrian survey were determined to have Low potential for occurrence in the BSA, and all have low potential to occur. 1. Least Bell's vireo occur in riparian areas with dense vegetation cover and trees for nesting. The project site is unlikely to support this species due to the lack of riparian habitat present. 2. Southwestern pond turtle occupy riparian habitat with slow moving waters with dense vegetation for foraging and hiding from predators. There is low potential for the project site to support this species due to the long distance an individual would have to travel from the perennial stream. 3. Monarch Butterfly utilize milkweed (Asclepius ssp.) as a host plant. The site survey was conducted in May which is outside of the appropriate time to survey for the plant. 4. Crotch's Bumble Bee inhabit largely undisturbed habitat where there is sufficient flower production by plants and can utilize burrows for nesting sites. Outside of nesting season the species will burrow underground to hide from predators and rest. The project site is unlikely to host this species and the density of flowering species is low. 4.5.2.5 Taxa With No Potential for Occurrence Eight special status wildlife taxa from desktop analysis were determined to have No potential for occurrence in the Biological Study Area. The Project site lacks vernal pool, wetland, and woodland habitats needed to support vernal pool fairy shrimp, riverside fairy shrimp, quino checkerspot butterfly, yellow -billed cuckoo, southwestern willow flycatcher, and California condor. Unarmored threespine stickleback and Santa Ana sucker are unable to access the BSA since the Project site lacks long term water sources for the species to travel. 4.6 Other Considerations 4.6.1 Wildlife Movement The Santa Clara River is largely undisturbed habitat with the potential for species to wander onto the Project site. While there is a four -foot height difference that separates the bank of the river from the Project site, small mammalian and herpetofauna may be able to climb this barrier. Migrating species such as birds and Monarch butterfly have the potential to pass through the area as well. Providing Environmental Solutions for a Developing World 22 Biological Resources Assessment Placerita Maintenance Yard Project 2047-24 May 2024 4.6.2 Nesting Birds Few trees are located within the Project site, which limits the opportunities for birds to nest. However, some shrub or ground nesting species might find suitable nesting locations at the far west end of Norland Drive where the vegetation is dominated by Common Sagebrush (Artemesia tridentate). All nesting birds and their eggs are protected by the Migratory Bird Treaty Act. Therefore, conservation measures described in Section 1.5 of this assessment should be followed. Specifically, a nesting bird survey should be conducted no less than five days before construction begins if work is to be conducted during the nesting bird season (February 1 to September 31). 5 Project Impacts The following impacts may result from implementation of the Proposed Project: 5.1.1 Impacts to Special Status Species and Habitat No impacts to special status species or habitat are expected to result from implementation of the proposed Project. The Project site has already been disturbed and provides little to no habitat for wildlife with the exception of shrub nesting birds along Norland Drive. Raptors may utilize the open area within the Project site for hunting lizards and small rodents, but no trees within the Project site are tall enough to support nesting raptors. Vegetation along Norland Drive may be too dense for burrowing and ground nesting species, but this vegetation does provide refuge for small mammals and reptiles. No burrows were found on the vacant lot of the proposed maintenance yard but soils along the eastern half of the lot may be suitable for burrowing species. There is low potential for four species and moderate potential for three species to occur within the BSA. Implementation of the proposed avoidance, minimization and mitigation measures described below would reduce the potential to impact any special status species or their habitat. 5.1.2 Impacts to Aquatic Resources No aquatic resources were observed within the Project site during a site visit on May 3, 2024, except for erosional undercutting observed along Norland Drive that leads to the Santa Clara River. No aquatic resources were mapped on the NWI mapper for the Project site, and a review of aerial photography does not show evidence of any resources. Implementation of the proposed avoidance, minimization and mitigation measures described below would reduce the potential to impact the portion of the Santa Clara River within the BSA. Specifically, best management practices (BMPs) such as storm water containment and erosion control on the Project site would reduce the potential to have any impacts on aquatic resources. 5.1.3 Impacts to Nesting Birds Impacts to nesting birds may occur as a result of vegetation clearing and grading along Norland Drive. Most plant species are not suitable for nesting birds with the exception of a large population of Common Sagebrush (Artemisia tridentate) located at the far west end of Norland Drive. Avoidance and minimization measures should be implemented to reduce the potential to impact to nesting birds. Specifically, surveys and/or exclusion methods should be conducted and implemented. If an active nest is discovered, an avoidance buffer may be required until the young have fledged. Providing Environmental Solutions for a Developing World 23 Biological Resources Assessment Placerita Maintenance Yard Project 2047-24 May 2024 5.1.4 Impacts to Wildlife Movement Implementation of the proposed Project would not have a direct impact on the movement of wildlife. Construction noise may temporarily deter movement from the adjacent Santa Clara River, but construction would be limited to daylight hours and wildlife would not be disturbed during the times they typically travel (dawn, dusk, and night). 5.2 Avoidance and Minimization Measures The following Avoidance and Minimization Measures are recommended to reduce the potential to impact special status species, sensitive habitats, and aquatic resources: 1. Ground disturbing work should take place in the dry season when rain is not forecasted. 2. Work should be restricted to periods of low rainfall (less than 0.25-inch per 24-hour period) and periods of dry weather (with less than a 50% chance of rain). No work will occur for a period of 24 hours after a rain event. 3. Erosion control measures should be installed prior to any storm events. 4. All work equipment will be washed at an offsite location. 5. All fueling and maintenance of vehicles and equipment will occur a minimum of 100 feet from aquatic resources. 6. All vehicles and equipment will be inspected for leaks prior to use. 7. Protocol level surveys should be conducted by a qualified biologist for the presence of Arroyo Toad, Western Spadefoot, and Southwestern Pond Turtle. If present, CDFW should be consulted to determine appropriate avoidance, minimization, and mitigation measures. 8. Pre -construction surveys should be conducted by a qualified biologist for California Gnatcatcher. 9. Pre -construction surveys should be conducted by a qualified biologist during the appropriate bloom time to determine if milkweed (host plant for the monarch butterfly) is present. If present, CDFW should be consulted to determine appropriate avoidance, minimization, and mitigation measures. 10. If work is to be conducted during the nesting bird season (February 1 to September 31), a nesting bird survey will be conducted no less than five days before the start of work. 6 Conclusions and Recommendations 6.1 Special Status Plant Species There is no suitable habitat for special status plant species within the Biological Study Area. No special status plants were observed during the site Assessment. 6.2 Special Status Wildlife Species The BSA has medium quality habitat for three special status species. Arroyo Toad, Western Spadefoot, and Southwestern Pond Turtle have potential to occur in the adjacent Santa Clara River, particularly during a rain event. Preconstruction surveys for these species should be conducted by a qualified biologist prior to any Providing Environmental Solutions for a Developing World 24 Biological Resources Assessment Placerita Maintenance Yard Project 204'7-24 May 2024 construction activities to determine if the species are present in the BSA. If present, CDFW should be contacted to determine if additional avoidance, minimization, and mitigation measures are required. Asurveyforthe presence of milkweed should be conducted to determine if potential habitatfor monarch butterfly is present within the BSA. If the host plant is discovered in the BSA, additional avoidance, minimization, and mitigation measures may be required. Preconstruction surveys for California Gnatcatcher and nesting birds should be conducted prior to the start of construction to avoid impacts to these species. Any species or nests observed should be mapped and appropriate buffer distances should be adhered to. The CDFW should be consulted regarding appropriate buffers. The potential for Least Bell's Vireo to occur within the BSA is unlikely as riparian woodland habitat is not present. Crotch Bumble Bee are also unlikely to occur in the BSA due to the lack of flowering plants in the BSA and the Project site is largely disturbed from previous development.

Providing Environmental Solutions for a Developing World iv BARGAS A Decade of Excellence June 25, 2024 Margaret Lin Phone: (323) 253-6577 Email: margaret@impactsciences.com Subject: California Gnatcatcher, Arroyo Toad, Southwestern Pond Turtle, Western Spadefoot, and Milkweed Survey Results for Placerita Maintenance Yard Project in Santa Clarita, Los Angeles County, California Dear Margaret, Bargas Environmental Consulting (Bargas) is pleased to provide this biological survey report for the construction of the Placerita Maintenance Yard Project (Project) located in the City of Santa Clarita, Los Angeles County, California (Figure 1). A field assessment survey conducted on May 3, 2024 determined that suitable habitat for California gnatcatcher, arroyo toad, southwestern pond turtle, western spade foot, and milkweed occurs within the Project site. Therefore, a focused pre -construction survey was conducted by Bargas biologist, Gregory Garcia for California gnatcatcher (Polioptila californica californica, CAGN) and monarch butterfly host plant milkweed species (Asclepius sp.) within the Project site and an adjacent 500-foot buffer surrounding the Project site on June 19, 2024. In addition, a second focused survey was conducted by Komodo Biological Services biologist, Christopher Taylor on June 22, 2024 for arroyo toad (Anaxyrus californicus), southwestern pond turtle (Actinemys pallida), and western spadefoot toad (Spec hammondii).. No California gnatcatcher or milkweed species were observed within the Biological Study Area during the June 19 survey. No arroyo toads, southwestern pond turtles, or western spadefoot toads were observed within the Biological Study Area during the June 22, 2024 survey. Project Location & Description The Project proposes to construct a maintenance yard on approximately 1.72 acres of vacant land at the end of Norland Drive with an expansion of the road by 12 feet. The Project site is located in Santa Clarita, Los Angeles County and is located between California State Route 14 (SR 14) and the Santa Clara River. Methods This report is informed by data collected during the field surveys on June 19 and June 22, 2024, the methods for which are described below. Definitions This report will use the following definitions for areas referred to herein: • Project site: The Project site is defined as the 1.72 acres being analyzed for Project entitlements. • Biologic al Study Area: The Biological Study Area is defined as the Project site and a 500-foot buffer as shown on Figure 2 (approximately 80.37 acres). Sacramento Valley w.- Inland Empire w.- Greater Los Angeles 'W.- San Diego 'W.- San Francisco Bay Area www.Bargas.com Z] Field Surveys Biological Resources Letter Report 2101-24 Placerita Maintenance Yard Focused Surveys June 25, 2024 Bargas biologist, Gregory Garcia, performed a reconnaissance -level biological survey on June 19, 2024. The survey began at 9:00 AM and was completed at 10:45 AM. The survey focused on determining the presence or absence of any California gnatcatcher or milkweed species located within the Project site and a 500 foot buffer. Meandering transects were conducted on foot throughout the entire survey area where possible. The area immediately north of the Project site is entirely developed and does not support wildlife species. A second reconnaissance -level biological survey was conducted on June 22, 2024 for arroyo toad, western spadefoot toad and southwestern pond turtle. The survey began at 10:00 AM and was completed at 2:00 PM. The survey focused on determining the presence or absence of any arroyo toad, western spadefoot toad and southwestern pond turtle. Biologist, Christopher Taylor, walked transects in suitable areas, including both sides of the stream banks and associated flood plain for the entirety of the survey area and 500 foot buffer. Results No California gnatcatcher, milkweed species, arroyo toads, western spadefoot toads, or southwestern pond turtles were observed within the Biological Study Area. However, due to the presence of suitable habitat within the previously mapped ranges for arroyo toads, western spadefoot toads, and southwestern pond turtles, presence should be assumed. Western toads in all life stages were also observed within the Biological Study Area. Discussion Seasonal and temporal factors may have influenced species detected. Wildlife activity was low during the June 19 and 22 surveys. When temperatures are high, California gnatcatcher may seek refuge in shadier areas. Additionally, it may be difficult to detect milkweed species through the brush due to the high density of vegetation in the Santa Clara River and along Norland Drive. It is the biological opinion of the survey biologist, Gregory Garcia, that any impacts to these species from the Project would be minimal. Suitable nesting and foraging habitat are found along Norland Drive. Noise from SR 14 and construction activities could deter individuals from using the Project site. It is recommended that a preconstruction survey be conducted prior to any vegetation removal on Norland Drive to mitigate any affects against California Gnatcatcher. While no arroyo toad, western spadefoot toad, or southwestern pond turtle were observed, suitable habitat providing sandy, gravelly soils and a slow moving stream were present to support all life stages for these species. It is the biological opinion of the survey biologist, Christopher Taylor, that any impacts to these species from the Project would be minimal. The location of the construction yard is upland from the streambed and associated flood plain and would not impact its bed, banks or flood zone. All three species are known to use suitable upland habitat; however, the proposed disturbance area includes previously disturbed hard packed ground that is unlikely to present significant opportunities for these species. Toads and turtles may use the disturbance area for overland travel or foraging, but are unlikely to be affected by construction. To mitigate risk to traveling toads and turtles, the following minimization measures are recommend: 1. A monitoring biologist should be present to relocate any excavated toads or turtles if excavation is occurring in previously undisturbed habitat. 2. Wildlife ramps should be installed in every trench at no more than a 30 foot inerval with a maximum slope of 3:1 if excavations are to be left open, or trenches should be completely covered after excavation and gaps should be sealed with soil around the perimeter. The greatest risk of project personnel impacting one of these three species comes during or immediately after a rain event. 3. A worker environmental awareness program (WEAP) should be conducted to train construction personel on the identification of these species. Providing Environmental Solutions for a Developing World 2 ZI Biological Resources Letter Report 2101-24 Placerita Maintenance Yard Focused Surveys June 25, 2024 Construction personel should contact a biologist immediately if any toad or turtle is observed. Western toads in all life stages were observed within the survey area. As it can be difficult to distinguish listed toads from common toads, we recommend that a biologist should be notified if any toads are observed.

Martha Lira, Contracts Administrator 811 W. 7th Street, Suite 200 Los Angeles, California 90017 TECHNICAL MEMORANDUM Subject: Phase II Environmental Site Assessment Placerita Yard Relocation Site 28837 Oak Springs Canyon Rd, Santa Clarita, CA 91387 Assessor's Parcel Number: 2840-001-271 EFI Global Project Number 045.12755 EFI Global (EFI) presents this Technical Memorandum to summarize the Phase II Environmental Site Assessment (ESA) activities conducted on a portion of Assessor's Parcel No. (APN) 2840-001-271, which is currently owned by the City of Santa Clarita, California (the Site; Figure 1). The Site is proposed as a replacement for the property currently occupied by Public Works' Placerita Yard (APNs 2833-005-902, - 903, and -904), which is used by the Operational Services and Road Maintenance Divisions. The Site is proposed to be land swapped with the Placerita Yard property under an agreement between the City and Los Angeles County (County) to support the City's Dockweiler Drive Extension Project. Based on the project description provided from Survey/Mapping & Property Management Division, the Site is a trapezoidal -shaped, 90,000-square foot lot located within the City of Santa Clarita limits. This assessment was performed based on the findings Los Angeles County Public Works Geotechnical and Materials Engineering Division Geology Investigations Section's Phase I Environmental Site Assessment (Phase 1), dated March 6, 2024, which identified construction debris piles located on -site consisting of trash, concrete, rebar, pipes, crushed asphalt, household trash and used oil filters. Additionally, stockpiles of undocumented soil and large aggregate stones were also reportedly present at the Site. Given the on -site conditions observed and the threatened or potential release of hazardous materials and/or contamination associated with the construction debris piles, the observed Site conditions were considered a recognized environmental concern (REC) for the Site. Therefore, the Phase I recommended a Phase II ESA to assess for potential impacts from apparent historical onsite dumping activities. Accordingly, EFI collected soil samples from a total of six (6) of the dumped stockpile locations to collect discrete soil samples representative of Site conditions for chemical analyses. The six shallow soil borings (SP1 through SP6) were advanced into stockpiles to approximately 1.5 feet below ground surface (bgs) at representative locations throughout the Site to assess for impacts from the former apparent dumping activities. Soil samples were collected and analyzed for total petroleum hydrocarbons, carbon chain analyses (TPH-cc), volatile organic compounds (VOCs) and Title 22 Metals. Presented in the following sections is a description of the Site, a summary of field activities, a summary of analytical results and EFI's conclusions/recommendations. SITE DESCRIPTION The Site is a mostly undeveloped, trapezoidal shaped, 90,000-square foot plot of land located south of California State Route 14 on Norland Drive (Figure 1). According to the County Assessor, the Site is fee - owned by the City of Santa Clarita with boundaries located within APN 2840-001-271, is zoned for 317 South Isis Avenue, Suite 207, Inglewood, CA 90301 Toll Free: 888-705-6300 Phone: 310-854-6300 Fax: 310-854-0199 www.EFIGlobal.com Pagel of 7 Technical Memorandum — Phase 11 Environmental Site Assessment Placenta Yard Relocation EFl Global Project Number 045.12755 commercial use, and borders the Lost Canyon River Trail Open Space. The Site appears to be minimally graded, is transected by an asphalt access road (Norland Drive) and does not contain any structures. The southern portion of the Site is partially located within the banks of the Santa Clara River. A tree -lined, southerly flowing, blue -line tributary of the Santa Clara River is located adjacent to the eastern border of the Site. The Site appears to be vacant and unoccupied; however, piles of construction debris from former dumping are located on -site. A Santa Clarita Valley water well (Pinetree Well 5) is located west of the Site. State Route 14 is located immediately to the north, and the area to the south, west, and east of the Site is bordered by the Los Canyon Open Space preserve consisting of the unchanneled Santa Clara River. FIELD ACTIVITIES Initial field activities pertaining to this investigation were completed on May 9, 2024, in general conformance with the email workplan. EFI returned to the Site on May 16 to collect the deeper samples, which were not collected during the first mobilization. Soil Sampling Locations The locations of the six (6) soil excavations (SP1 through SP6) advanced as part of this assessment are presented on Figure 2. Borings SP1 through SP6 were advanced at stockpile locations throughout the Site to assess the Site for potential impacts from the construction debris piles. Soil Sample Collection and Handling Procedures On May 9, 2024, at each sampling location SP1 through SP6, a soil sample was initially collected at depths of 0 to 0.5 foot bgs. Hand tools (shovel and trowel) were used to excavate to the sampling depth of 0.5- feet bgs. On May 16, 2024 a deeper sample was collected similarly from each location at a depth of 1.5 feet bgs. Soil samples were collected at the designated sampling depth by retrieving a representative volume of soil from the shovel and immediately transferring the soil into pre -cleaned, laboratory -provided, glass jars. The glass jars were immediately sealed with Teflon@ lined, tight fitting caps. All collected soil samples intended for VOC analysis were additionally subsampled using US Environmental Protection Agency (EPA) Method 5035 sampling methodology for VOC analysis. The soil sampling locations are shown in Figure 2. All soil samples were labeled, recorded on a chain -of -custody form, and chilled pending transportation and submittal to Pace Analytical Laboratory (Pace) of Bakersfield, California, a State -certified analytical laboratory. Chain -of -custody documentation and protocol were maintained during sample collection through submittal to the analytical laboratory. Following completion of soil sampling, each shallow excavation was backfilled with soil cuttings. No investigation -derived waste was generated during this investigation. Descriptions and classifications of soil encountered in the stockpiles are provided below. Encountered Soil Types Soil types encountered during this investigation were generally classified as well -graded Sand (USCS soil type symbol "SW"); fine to coarse grain sand; generally light brown, brown or dark brown where mixed with asphalt; loose to medium dense; dry (at surface) to moist. It should be noted that steel, polyvinyl chloride (PVC), concrete and asphalt debris were noted in location SP1; concrete chunks were additionally noted in locations SP2 and SP6; additional asphalt chunks were noted in locations SP3 and as mixed with soil in location SP5. Wooden pallets and debris were noted in location SP4. Asphalt was most prevalent in borings SP3 and SP5, which indicated brown and dark drown color. The presence of asphalt was generally recognizable in the soil making up the stockpiles and was noticeably absent in other areas. Groundwater was not encountered during our soil sampling activities. With the exception of asphalt discoloring the soil where present and mixed (i.e., locations SP5), chemical staining and/or odors were not present in any soil samples. �` efi global Page 2 of 7 Technical Memorandum — Phase 11 Environmental Site Assessment Placenta Yard Relocation EFI Global Project Number 045.12755 CHEMICAL ANALYSIS Each of the 0.5-foot soil samples collected from borings SP1 through SP6, were analyzed for total petroleum hydrocarbons (TPH), full carbon chain analysis (TPH-cc) by EPA Method 8015B, VOCs by EPA Method 8260B and Title-22 Metals by EPA Methods 6010B/7471A. The remaining deeper soil samples collected from each location were initially placed on hold with the laboratory for potential future analysis pending results from the 0.5-foot samples. Upon receipt of the shallow soil data, the deeper soil sample collected below the most impacted shallow soil sample was analyzed. Soil chemical analysis was completed off -site by Pace. The laboratory analytical reports are included as Appendix A SOIL ANALYTICAL RESULTS This section presents the chemical analytical results of soil sample analyses. Petroleum Hydrocarbons in Soil Petroleum hydrocarbons can be characterized by the length of their constituent carbon chains. Carbon C4- C12, C13-C22, and C23-C36 are commonly interpreted as gasoline (TPH-g), diesel (TPH-d), and oil (TPH- o) range hydrocarbons, respectively. TPH-cc (a full carbon chain analysis) includes all the petroleum hydrocarbons C4 through C36. TPH-d and/or TPH-o were detected in each of the seven soil samples collected and analyzed from the stockpiles for this assessment. Soil analytical results for TPH-cc are included in Table 1 and summarized below: • TPH-g was not detected in any of the seven soil samples submitted for laboratory analysis. • TPH-d was detected in three of the seven shallow (0.5-foot) soil samples up to a maximum concentration of 74 milligrams per kilogram (mg/kg) in sample SP5-S-0.5. TPH-d was not detected in the other four soil samples analyzed. • TPH-o was detected in all seven soil samples collected and analyzed, up to a maximum concentration of 2,400 mg/kg in sample SP5-S-0.5. In general, exposure to contaminants in soil through dermal contact, inhalation of particulate matter, and ingestion may pose risks to human health (including cancer and non -cancer risks). To evaluate if contaminants represent a significant risk to human receptors, the detected concentrations are compared to regulatory screening levels that have been established for this purpose. Human Health Screening Levels (HHSLs) are developed using default exposure and toxicity criteria to provide conservative screening levels for cancer and non -cancer risks. Concentrations of contaminants below such screening levels are not considered to represent a significant risk to human receptors. Applicable HHSLs have been established by the EPA, the California Department of Toxic Substances Control (DTSC), and the San Francisco Bay Regional Water Quality Control Board (SFBRWQCB) as follows: Regional Screening Levels (RSLs) have been developed by the EPA using default exposure and toxicity criteria to provide conservative screening levels, whereby concentrations of contaminants below such levels are not considered to represent a significant risk to human receptors (including cancer and non -cancer risks). EPA publishes RSLs periodically. The most current release is dated May 2024. In general, the "Target Risk = 1 E-06, Target Hazard Quotient = 1.0" RSL data set is appropriate to use. DTSC recommends the use of alternative screening levels based on toxicity criteria reviewed by DTSC's Human and Ecological Risk Office (HERO). DTSC-modified Screening Levels (DTSC-SLs) are updated periodically and published in Human Health Risk Assessment (HHRA) Note Number 3, DTSC-modified Screening Levels (DTSC-SLs), Release Date: June 2020 — Revised May 2022 (Note 3). For compounds that have screening criteria listed in Note 3, the DTSC-SLs are used instead of RSLs. efi globa I Page 3 of 7 Technical Memorandum — Phase 11 Environmental Site Assessment Placenta Yard Relocation EFl Global Project Number 045.12755 SFBRWQCB has established Environmental Screening Levels (ESLs) for HHSLs and for Leaching to Groundwater. ESLs are updated periodically, and the most recent publication is dated January 24, 2019. ELS are used for compounds that do not have established DTSC-SLs or RSLs. To evaluate if the TPH-d and TPH-o concentrations detected in soil represent an unacceptable risk to human receptors, the detected concentrations were compared to the ESLs for Commercial/Industrial Soil (1,200 and 180,000 mg/kg, respectively). As shown in Table 1, the detected concentrations are well below the human health screening levels. Thus, TPH-d and TPH-o detected in soil do not represent an unacceptable risk to the health of commercial occupants of the Site. In addition to potentially impacting human health, contaminants in soil (i.e., secondary sources) also have the potential for vertical migration into groundwater bodies farther below grade. Lithologic structures between the impacted soil and the groundwater table often serve as attenuating features, which may restrict or retard vertical migration to concentrations that do not represent significant risks to groundwater. To evaluate whether the TPH concentrations detected in the soil samples from the Site represent a significant risk to groundwater quality, the concentrations were compared to the ESLs for Leaching to Groundwater, as established by the SFBRWQCB. As shown in Table 1, the detected TPH-d concentrations did not exceed the ESL of 7,300 mg/kg; no screening level for TPH-o has been established for the protection of groundwater. Thus, TPH in soil does not represent a potential threat to groundwater quality at the Site. Additionally, a deeper soil sample (SP5-S-1.5) collected below the impacted sample with the highest concentrations (sample SP5-S-0.5) also showed concentrations below the applicable human health and groundwater screening levels. The soil samples analyzed for this assessment did not contain TPH at concentrations exceeding existing HHSLs for the protection of human health or ESLs for the protection of groundwater. Therefore, the soil sampled in the stockpile areas does not represent a potential threat to human health or to groundwater. Volatile Organic Compounds in Soil As shown in Table 1, VOCs were not detected at or above their respective laboratory practical quantitation limit (PQL), therefore, VOCs in soil do not represent a significant environmental concern at the Site. Title 22 Metals in Soil A summary of analytical results of Title 22 Metals in soil is presented in Table 1. In general, exposure to contaminants in soil through dermal contact, inhalation of particulate matter and ingestion may pose risks to human health (including cancer and non -cancer risks). To evaluate if the detected metals in soil represent a significant risk to human receptors, the detected concentrations were compared to regulatory screening levels that have been established using default exposure and toxicity criteria to provide conservative human health screening levels for cancer and non -cancer risks. Concentrations of contaminants below such screening levels are not considered to represent a significant risk to human receptors. RSLs have been developed by the EPA using default exposure and toxicity criteria to provide conservative screening levels, whereby concentrations of contaminants below such levels are not considered to represent a significant risk (including cancer and non -cancer risks) to human receptors. EPA publishes RSLs periodically and the most recent iteration was published in May 2024. The California DTSC recommends the use of alternative screening levels based on toxicity criteria reviewed by DTSC's HERO. DTSC SLs are updated periodically and published in Note 3, Release Date: June 2020 -revised May 2022. For compounds that have screening criteria listed in Note 3, the alternative screening levels are used instead of RSLs. To evaluate if the metals detected in soil represent a significant risk to human receptors, the concentrations of metals detected in soil were evaluated against screening levels for commercial/industrial soil. None of e-fi gioba I Page 4 of 7 Technical Memorandum — Phase 11 Environmental Site Assessment Placerita Yard Relocation EFl Global Project Number 045.12755 the detected concentrations of metal constituents exceeded their respective commercial/industrial human health screening levels. Accordingly, the presence of metals in the soil samples collected and analyzed from the soil stockpiles are not indicative of a threat to human health nor would the detected concentrations of any metals indicate they would be classified as a hazardous waste (state or federal). CONCLUSIONS AND RECOMMENDATIONS EFI conducted this Phase II ESA on a portion of APN 2840-001-271, which is currently owned by the City of Santa Clarita, California, and is proposed as a replacement for the property currently occupied by Public Works' Placerita Yard (APNs 2833-005-902, -903, and -904; see Figure 2). A total of six (6) soil borings (SP1 through SP6) were advanced at dumped stockpile locations throughout the Site to facilitate the collection of soil samples to assess for shallow soil impacts resulting from the historical soil, household and construction debris dumping. The 0.5-foot soil samples collected from each boring were analyzed for TPH- cc, VOCs and Title 22 Metals. A deeper sample (SP5-S-1.5) from the location with the highest concentrations observed in the shallow samples (SP5-S-0.5) was additionally analyzed for TPH-cc and VOCs. The following provide the results and EFI's Conclusions and Recommendations: TPH-d and TPH-o were detected at maximum concentrations of 74 mg/kg and 2,400 mg/kg in the 0.5-foot soil samples collected from stockpile SP5 (sample SP5-S-0.5). A deeper sample collected from this boring (SP5-S-1.5) was ND for TPH-g and TPH-d, and indicated a TPH-o concentration of 2,000 mg/kg. None of the detected TPH exceeds their respective ESLs for the protection of human health or groundwater. Therefore, the detected TPH in soil is considered de minimis and is not considered a threat to human health or groundwater. VOCs were not detected at or above the laboratory PQL in any of the samples analyzed, therefore, VOCs in soil are not a significant concern in the areas assessed. Several Title 22 Metals were detected in the six (6) 0.5-foot soil samples analyzed, all at concentrations well below the established human health screening levels established for metals concentrations in soil or within background concentrations, therefore, the metals detected in soil during this investigation are considered background and de minimis in nature. Based on the results of this investigation, a significant risk to human health or the environment has not been identified. However, it is obvious that dumping of construction debris including asphalt, wood, bricks, concrete, household trash, etc, has occurred at the Site and the TPH-impacted soil stockpiles will need to be properly handled and disposed. Accordingly, it is EFI's opinion that no further investigation is warranted in regard to the historical dumping identified in the Phase I ESA as a REC. However, it is recommended that the existing stockpiles be profiled for disposal, accepted at an appropriate waste receiving facility, and that the soil stockpiles are loaded, transported and properly disposed. The laboratory data attached herein can be used to profile the stockpiled soil for disposal at an appropriate facility. Based on the sampling performed on the soil stockpiles for this assessment, the previously dumped material may be disposed under profile as regulated non -hazardous waste at an appropriate licensed receiving facility. Additionally, EFI recommends the excavation, loading and disposal activities be performed under a Soils Management Plan (SMP) prepared forthe Site, forthe instance that unknown or unanticipated contaminants or containers (sludge, buckets or bottles of unknown liquids, drums or other unknown containers) are encountered in the dumped stockpiles during removal. efi globa I Page 5 of 7 Technical Memorandum — Phase 11 Environmental Site Assessment Placenta Yard Relocation EFl Global Project Number 045.12755 SIGNIFICANT ASSUMPTIONS, LIMITATION, AND RELIANCE This report has been prepared in accordance with generally accepted environmental methodologies and industry standards as they relate to the Data Quality Objectives of the assessment. No warranties, expressed or implied, are made as to the professional services provided under the terms of EFI Global's contract(s) or specified in this report. This assessment has been conducted, in part, based on information, data or reports provided or prepared by others. EFI Global reviews and interprets these documents in good faith and relies on that the provided data and documents are true and accurate. Environmental conditions at the site were assessed or interpreted within the context of EFI Global's contract(s) and existing environmental regulations of applicable jurisdiction(s) as of the date of the report. Regulatory requirements, regulations and guidance are subject to change after the date of the report. Unless otherwise stated in the report, evaluating compliance of past, present, or future owners with applicable local, provincial, and federal government laws and regulations was not included within the scope of the assessment. The environmental assessment is limited by the availability of information at the time of the assessment. The conclusions and recommendations regarding environmental conditions presented in this report are based on a scope of work authorized by the Client. It is possible that unreported conditions impairing the environmental status of the site may have occurred which could not be identified. EFI Global's opinions cannot be extended to portions of the site that were unavailable for direct access and observation reasonably beyond the control of EFI Global or outside of the scope of the assessment. Environmental assessment activities, particularly the sampling of soil, vapor (air), groundwater and structure materials, represent those conditions which are present at the time of sampling within the immediate vicinity of the sample(s) collected. Although sampling plans are developed to provide what is interpreted as sufficient coverage within the assessment area to achieve the investigative objectives, no extent of sampling can guarantee all environmental conditions, potential chemicals of concern (man-made or naturally occurring) and concentrations at which they occur have been identified and quantified absolutely.

A concentration of ten times the STLC is sometimes used as a trigger to conduct further analysis (i.e., the soluble analysis) of a sample to determine disposal requirements. Wastes with soluble concentrations above this value are considered hazardous for the purposes of disposal under California regulations. TCLP = Toxicity Characteristic Leaching Procedure concentration in mg/L as identified in the Code of Federal Regulations. A concentration of 20 times the TCLP is sometimes used as a trigger to conduct further analysis (i.e., the soluble analysis) of a sample to determine disposal requirements. Wastes with soluble concentrations above this value are considered hazardous for the purposes of disposal under federal regulations. TTLC = Total Threshold Limit Concentration as identified in Title 22 of the California Code of Regulations.

Introduction ��� efi global Impact Sciences, Inc., (referred to hereunder as the client) retained EFI Global to perform limited sampling of suspect asbestos containing materials (ACM) located on and around stockpiles of soil and construction debris located within the Project Area (See project area map in Appendix I). The limited assessment was performed on May 9, 2024, by Joshua Everett, a DOSH Certified Asbestos Consultant (DOSH Cert No. 19-6687). Please note that the subject property is a vacant lot, and no physical structures were present at the time of the assessment. 2. Asbestos Assessment The purpose of this assessment was to conduct bulk sampling in order to determine the presence or absence of Asbestos Containing Material (ACM) in at the subject property. The scope of this assessment included reviewing any provided building records and/or previous investigation records, visually identifying homogeneous sample areas, collecting bulk samples of suspect ACM / ACCM, recording the friability and condition of suspect ACM/ACCM, interpreting the laboratory results, and producing a written report of findings and recommendations. The sampling was performed in accordance with requirements of the following regulations: • Asbestos Hazard Emergency Response Act (AHERA); 40 CFR 763 Subpart E • Asbestos School Hazard Abatement Reauthorization Act (ASHARA); Section 206 of the Toxic Substance Control Act • National Emissions Standards for Hazardous Air Pollutants (NESHAPS); 40 CFR 61 Subpart M. This report is a record of activities, observations, analytical results, and recommendations performed to date. >., i Asbestos Results Summary The laboratory results indicate that the materials sampled during this assessment were found to be None Detected for asbestos content. Page 1 of 4 Placertio Yard Relocation Project Limited Asbestos Assessment EFI Global Project Number: 045.12755 No other materials were sampled as part of this assessment. Please refer to the Homogenous Material Sampling Table and Appendices for Materials, their locations and approximate quantities. 2.2 Methodology All samples were collected using a clean knife, chisel or the appropriate tools. Each sample was extracted carefully so as not to disturb adjacent materials while still penetrating through all layers of the material sampled. Each sample was sealed in the appropriately sized plastic zip lock bag and the bag then labeled with a unique identification number. The sample number, description and location were then recorded on a log and plotted on a floor plan of the structure or area. Sampling tools were cleaned after collecting each sample. Any excess dust or debris from the sample location was cleaned using a moistened cloth. Whenever possible, samples were collected from previously damaged portions of the material in order to minimize damage to the material. A total of twenty-four (24) samples were submitted to LA Testing in South Pasadena, CA which is accredited under the NIST/NVLAP program for asbestos in bulk material by polarized light microscopy and the State of California for asbestos analysis. AIH Laboratory is NIST/NVLAP and California ELAP certified. LA Testing is located at 520 Mission Street, South Pasadena, CA 91030 and can be reached at 323-254-9960. The analyses of the samples in this report were performed using polarized light microscopy using the EPA method 600/R-93/116. The phase abundances provided are visually estimated and expressed as percent area. Total percentage of sample constituents may total greater than 100 due to trace amounts. The limit of detection for this analytical method is less than one percent. In multilayer samples, unless otherwise specified, the asbestos concentration is reported for the layer where asbestos is found. These results lie within the statistical limits of variability calculated for standard reference samples routinely analyzed in the laboratory. On a per sample basis, the accuracy and precision of the results depend on the type of sample and its asbestos content. 2.3 Regulatory Limits Government agencies have promulgated different regulatory threshold levels to classify materials containing asbestos. The levels of asbestos content and the terms used to classify them differ. Listed below are the current regulatory agencies that have defined materials containing asbestos, along with the respective action levels, regulatory terminology and applicability: Q _j efi global Page 2 of 4 Placertio Yard Relocation Project Limited Asbestos Assessment EFI Global Project Number: 045.12755 Agency / Action Level (% Regulation Regulatory Code Weight) Terminology Applicability Asbestos -Containing CAL OSHA 8 CCR Section > 0 10� Construction Material Removal Work in 341.6(c) (ACCM) California Fed OSHA 29 CFR Section > 1.0% Asbestos -Containing Removal Work in 1926.1101(b) Material (ACM) United States 40 CFR Part 61 > 1% and Regulated Asbestos- Transport and NESHAP Subpart M Friable Containing Material (RACM) Disposal of Waste in United States 2.4 Homogeneous Sample Materials Table Homogeneous materials are defined as surfacing materials, thermal system insulation materials or miscellaneous materials that are uniform in color and texture. Homogenous sample areas are the areas where homogenous materials are located. Multiple sample locations are selected within each homogenous sample area to be a true representation of each homogenous material. Typically, a minimum of three (3) samples must be collected from each homogeneous area when sampling materials that may have variable asbestos content because it was batch mixed or applied by different contractors. High asbestos content variability is especially true of surfacing materials (sprayed -on and troweled on materials like plaster, fireproofing, acoustic ceiling, plaster) and thermal system insulation (TSI) used to insulate pipes, boilers, tanks or ducts to prevent heat loss. As many as 9 samples may be collected of surfacing materials when they cover large surface areas. Materials that appear to be homogeneous may in fact be different materials, installed at different times and have different material content in terms of asbestos; only laboratory testing can determine whether they are really the same homogeneous area. The below table presents the homogenous materials identified during the assessment and the asbestos content of those identified materials. The homogenous materials found to contain asbestos are listed in bold type. Asbestos Material Sample Material Friability Location Content Quantity Condition Number Description *** (% Weight) * ** None CC-1A to CC-1E Asphalt Debris Project Site Detected None CC-2A to CC-2E Concrete Debris Project Site Detected None CC-3A to CC-3E Fibrous Debris Project Site Detected Drywall and None CC-4A to CC-4C Project Site --- --- --- Plaster Debris Detected Paper / Mastic None CC-5A to CC-5C Project Site Debris Detected Insulation None CC-6A to CC-6C Project Site Debris Detected ** All quantities are approximations and should be verified by an abatement contractor. *** Non friable materials may be rendered friable during removal by mechanical or other aggressive methods.

Interpretation and use of test results are the responsibility of the client. This report relates only to the samples reported above, and may not be reproduced, except in full, without written approval by LA Testing. LA Testing bears no responsibility for sample collection activities or analytical method limitations. The report reflects the samples as received. Results are generated from the field sampling data (sampling volumes and areas, locations, etc.) provided by the client on the Chain of Custody. Samples are within quality control criteria and met method specifications unless otherwise noted. The above analyses were performed in general compliance with Appendix E to Subpart E of 40 CFR (previously EPA 600/M4-82-020 "Interim Method") but augmented with procedures outlined in the 1993 ('final") version of the method. This report must not be used by the client to claim product certification, approval, or endorsement by NVLAP, NIST or any agency of the federal government. Non -friable organically bound materials present a problem matrix and therefore LA Testing recommends gravimetric reduction prior to analysis. Unless requested by the client, building materials manufactured with multiple layers (i.e. linoleum, wallboard, etc.) are reported as a single sample. Estimation of uncertainty is available on request.
