FINDINGS OF FACT. The City Council does hereby make the following findings of fact: A. The approximately 87 -acre Sand Canyon Plaza Mixed Use Project (Project) site is located at the northeast corner of Sand Canyon Road and Soledad Canyon Road. Approximately 84 acres of the Project site are located in the Mixed Use Neighborhood (MXN) zone and General Plan land use designation, and approximately 2.5 acres in the southeast corner of the site are located in the Urban Residential 3 (UR3) zoning and General Plan land use designation. Approximately 34 acres in the southwest corner of the site are located within the Planned Development (PD) overlay zone. No development is proposed in the UR3 zone. The MXN zone is intended for mixed-use development, which is encouraged to integrate residential uses with complementary commercial uses. The MXN zone allows for maximum density of 18 dwelling units per acre. Approximately 77 acres of the site are dedicated to residential land uses and accompanying open space. Under this designation, and not taking into account Hillside Ordinance requirements, the Project site could support up to 1,386 residential units. Under the MXN and UR3 designations, the site could accommodate up to 217,800 square feet of commercial uses. B. The Project site was previously disturbed for the construction of a 123 -unit manufactured home park and associated infrastructure, along with roadway improvements for Soledad Canyon Road and drainage infrastructure along Sand Canyon Road. The park is in the process of being closed, with the site being cleared and coaches being removed from the site. The property owner received approval from the Manufactured Home Rental Adjustment Panel (MHRAP) to close the park on December 17, 2008, and began removing coaches from the Project site. Due to the downturn in the economy, some coaches were returned to the site and rented out on month- to-month leases. The owner has agreements in place for the purchase and relocation of all remaining owner -occupied units on the site, and will continue to remove these coaches from the site, in accordance with Resolution No. MHP 08-03 of the MHRAP. C. Surrounding land uses at the site include a mixture of residential uses and undeveloped property to the north, residential uses to the east, a mix of commercial uses and transportation corridors to the south, with a mix of commercial and residential uses to the west of the site. State Route 14 (SR14) is located to the south of the site, across Soledad Canyon Road, with the Santa Clara River to the south of SR -14. D. On May 28, 2014, an application for Master Case No. 14-077, the Sand Canyon Mixed Use Project, was filed by Sand Canyon Plaza, LLC, (applicant) with the City of Santa Clarita (City). The original entitlement application (collectively, Entitlements) includes: 1. Tentative Tract Ma 5p 3074 to subdivide the property to allow for the construction of 580 residential units (146 detached/attached condominium units, 122 attached townhome units, and 312 apartments), up to 56,000 square feet of commercial uses (retail and restaurants), a 60,000 square -foot assisted living facility (up to 120 beds), other lots for landscape/open space, private streets, and recreation areas. 2. Conditional Use Permit 14-014 to allow for development within a PD overlay zone, and to permit the assisted living facility in the MXN zone. 3. Hillside Development Review 14-001 to allow for development on slopes over 10%. 4. Ridaeline Alteration Permit 14-001 to allow for development in a Ridgeline Preservation (RP) overlay zone, more specifically to allow for development within 100 feet vertically and horizontally of a significant ridgeline. 5. Minor Use Permit 14-016 to allow for the commercial Floor Area Ratio (FAR) to be less than the minimum required by the MXN zone. Under the MXN zone requirements, the minimum FAR of commercial uses on the site would be 0.2:1, or 87,120 square feet. The applicant's original proposal was to develop the site with up to 56,000 square feet of commercial uses, which is an FAR of 0.13. 6. Oak Tree Permit 14-008 to allow for the removal of two non -heritage oak trees and to permit grading to encroach within the protected zone of one heritage oak tree. E. As detailed in Resolution No. P17-12 (in attached Planning Commission Packet, herein incorporated by reference), the Project was revised to include the development of up to 580 residential units, up to 60,000 square feet of commercial uses (retail and restaurants), and an 85,000 square -foot assisted living facility (up to 140 beds). The final residential product mix includes 312 apartment units, 149 attached townhome units, and 119 single-family condominium units, consisting of two planning areas totaling 71 units and 48 units. Additional components of the Project include two private recreation areas, including a two -acre private park, private and public street improvements, private and public trail improvements, and other areas dedicated to required infrastructure and open space. Approximately one acre of the existing Sand Canyon Road right-of-way would be vacated by the City and included in Planning Area 2 of the Project, as it will no longer be necessary for roadway purposes. F. Environmental conditions on the Project site have been altered substantially by existing and historical uses of the property, including the manufactured home park, grading, utility construction and maintenance, and off-road vehicle use. G. The Project concentrates development on the flatter and disturbed portions of the site. The majority of residential units (75%) and commercial land uses are in areas with less than 25% grade. Approximately 461 of the 580 residential units would be located in a portion of the site with an average cross slope of 13% or less. The Project design includes the preservation of the one heritage oak tree located on the site. H. In accordance with the California Environmental Quality Act (CEQA), the City is the lead agency and the City Council is the decision-making body for the Project. The Planning Commission is a recommending body for the Project. The City determined that the Project may have a significant effect on the environment and an Environmental Impact Report (EIR) must be prepared for the Project. The City determined that the following areas must be addressed in the EIR for the Project: aesthetics; agriculture and forestry resources; air quality; biological resources; cultural resources; geology and soils; greenhouse gas/climate change; hazards and hazardous materials; hydrology and water quality; land use; mineral and energy resources; noise; population and housing; parks and recreation; fire protection; police protection; schools; library services; traffic and circulation; solid waste; wastewater; and water supply. J. A Notice of Preparation (NOP) for the Project was circulated to affected agencies, pursuant to CEQA and the State CEQA Guidelines, from April 30, 2015, to May 29, 2015. Agencies that received the NOP include, but are not limited to, the County of Los Angeles, Los Angeles Regional Water Quality Control Board, California Department of Fish and Wildlife, South Coast Air Quality Management District, law enforcement agencies, school districts, waste haulers, water agencies, and transportation agencies serving the Santa Clarita Valley, in accordance with CEQA's consultation requirements. Comments from public agencies and organizations were received in response to the NOP. K. A scoping meeting was held at the City of Santa Clarita Activities Center on May 27, 2015, to obtain information from the public as to issues that should be addressed in the EIR. Notice of the scoping meeting was published in The Signal newspaper on April 30, 2015, and was mailed to all property owners within 1,000 feet of the Project site, in addition to approximately 55 agencies. Three people attended the scoping meeting. L. On January 18, 2017, the Planning Commission conducted a site tour of the Project site. M. The City prepared a Draft EIR for the Project that addressed all comments received on the NOP. The Draft EIR was circulated for review and comment by affected governmental agencies and the public, in compliance with CEQA. Specifically, the Notice of Availability/ Notice of Completion for the Draft EIR was filed, posted, and advertised on March 3, 2017, and the 45 -day public review period ended on April 17, 2017, at 5:00 p.m., in accordance with CEQA. Late written comments received prior to May 10, 2017, were responded to in the Draft Final EIR Responses to Comments. Draft Responses to Comments were forwarded to those commenting agencies and other commenters in advance of the June 6, 2017, Planning Commission public hearing. Oral and written comments received on the Draft EIR have been responded to, and those comments received after the Planning Commission's review of the Project will be responded to prior to certification and approval of the Project by the City Council, if granted. N. The City also prepared a Planning Commission Final EIR (June 2017). The Planning Commission Final EIR complied with all applicable CEQA requirements, and contained draft responses oral and written comments received prior to May 10, 2017. The Planning Commission Final EIR also contained a description of modifications to the Project made in response to public comment and Planning Commission changes. O. The Project was duly noticed in accordance with the noticing requirements for each of the Project entitlements. The Project was advertised in The Signal, through on-site posting 14 days prior to the hearing, and by direct first-class mailing to property owners within 1,000 feet of the Project site. In addition, the date and time of each public hearing was posted on two signs at the ` Project site. P. The Planning Commission held a duly -noticed public hearing on the Project on February 21 that was continued to March 21, May 16, and June 6, 2017. The hearings were held at City Hall, 23920 Valencia Boulevard, Santa Clarita, at 6:00 p.m. The Planning Commission closed the public hearing on June 6, 2017. 1. On February 21, 2017, the Planning Commission opened the public hearing for the Project, received a presentation from staff on the Project setting, a detailed description of the requested entitlements, and a detailed description of the Project proposed under Master Case No. 14-077. In addition, the Planning Commission received a presentation from the applicant, and received public testimony regarding the Project. 2. On March 21, 2017, City staff responded to questions raised by the Planning Commission at the Planning Commission meeting on February 21, 2017. In addition, staff made a detailed presentation on the Draft EIR Sections (Aesthetics, Agricultural and Forestry Resources, Air Quality, Biological Resources, Cultural Resources, Geology and Soils, Greenhouse Gas Emissions/Climate Change, Hazards and Hazardous Materials, Hydrology and Water Quality, Land Use, Mineral and Energy Resources, Noise, Population and Housing, Parks and Recreation, Fire Protection, Police Protection, Schools, Library Services, Traffic and Circulation, Solid Waste, Wastewater, Water Supply, and Project Alternatives). The Planning Commission received a presentation from the applicant regarding modifications proposed to the Project to address comments received at the February 21, 2017, Planning Commission meeting to increase the commercial component of the Project and reduce the development proposed in the RP overlay zone. In addition, the Planning Commission received public testimony regarding the Project. 3. On May 16, 2017, City staff responded to questions raised by the Planning Commission and presented a revised site plan that incorporated the changes presented by the applicant at the March 21, 2017, meeting. At the conclusion of the hearing, the Planning Commission directed staff to incorporate the Project modifications into the revised site plan and/or Conditions of Approval for the Project: a. Elimination of grading on the northern portion of the significant ridgeline through the transfer of 27 units from Planning Area 5 to Planning Area 3. This Project revision incorporates aspects of Draft EIR Alternative 3 (Ridgeline Preservation); b. Creation of a two -acre private park in Planning Area 5 to further enhance recreational opportunities on the Project site; Increase to the assisted living facility by 10,000 square feet (from 75,000 square feet to 85,000 square feet) to accommodate up to 140 beds and an increase to the commercial component of the Project site by 4,400 square feet (from 55,600 square feet to 60,000 square feet). This Project revision incorporates aspects of Draft EIR Alternative 2 (Increased Commercial and Office); d. Addition of a three-level, 264 -space parking structure to Planning Area 1; and e. Require, as a condition of approval, the applicant to re -design the building layout in Planning Area 2 (locating buildings along the Sand Canyon Road frontage) to further reduce noise impacts to adjacent properties. In addition, a condition of approval has been added to require enhanced landscaping along Sand Canyon Road. Q. On June 6, 2017, the modified site plan, Planning Commission Final EIR, resolutions, and Conditions of Approval were presented to the Planning Commission. The Commission also received public testimony regarding the Project. As a result of comments received from the Planning Commission, City staff, governmental agencies, and the public, the Project was modified by the Planning Commission. The revised site plan recommended by the Planning Commission proposes a total of 580 residential units, 60,000 square feet of commercial floor area, an 85,000 square -foot assisted living facility, and a two -acre private park along with other recreational amenities. R. At the conclusion of the June 6, 2017, public hearing, the Planning Commission voted to recommend that the City Council certify the Planning Commission Final EIR (see Resolution P17-11 in Planning Commission Packet) and approve the Project as revised (see Resolution P17-12 in Planning Commission Packet). The Planning Commission also recommended that the City Council adopt: (1) a Statement of Overriding Considerations for those impacts of the Project that cannot be mitigated to less -than -significant levels; and (2) the Mitigation and Monitoring and Reporting Plan (MMRP). S. The Planning Commission considered the Draft EIR (March 2017) and Planning Commission Final EIR (June 2017) prepared for the Project, as well as information in staff reports, public testimony, and letters submitted to the Planning Commission, prior to recommending approval of the Project. T. Following the June 6 public hearing, the City prepared the Final EIR (August 2017). The Final EIR contained copies of all comment letters, responses to oral and written comments received on the Draft EIR, and results from updated biological surveys conducted in the spring of 2017 but not completed by June 6. Notice of the Final EIR's availability was provided on August 30, 2017, to commenting agencies, organizations and persons. U. The City Council held a duly -noticed public hearing on the Project on September 12, 2017. This hearing was held at City Hall, 23920 Valencia Boulevard, Santa Clarita, at 6:00 p.m. V. The City Council received public testimony, closed the public hearing, certified the Final EIR, and adopted all necessary approval documents (e.g., resolutions) for approval of the Project. The Draft EIR (March 2017), Planning Commission Final EIR (June 2017) and Final EIR (August 2017) have been prepared and circulated in compliance with CEQA. W. Based upon the Draft EIR (March 2017), the Planning Commission Final EIR (June 2017), and Final EIR (August 2017), staff and consultant presentations, staff reports, applicant presentations, and public comments and testimony, the City Council finds that the Project will not adversely affect the health, peace, comfort, or welfare of persons residing in the area; nor will the Project be materially detrimental to the use, enjoyment, or valuation of property in the vicinity of the Project site; nor will the Project jeopardize, endanger or otherwise constitute a menace to the public health, safety, or general welfare since the Project conforms with the Zoning Ordinance and is compatible with surrounding land uses. X. Additionally, the City Council finds that all public hearings pertaining to the Project were duly noticed in accordance with noticing requirements for each of the entitlements. The Project was advertised in The Signal, through on-site posting 14 days prior to each hearing, and by direct first-class mailing to property owners within 1,000 feet of the Project site. Y. The location of the documents and other materials that constitute the record of proceedings upon which the decision of the City Council is based for the Master Case No. 14-077 Project file is with the Community Development Department, specifically in the custody of the Director of Community Development. SECTION 2. CEQA REQUIREMENTS. The City Council does hereby make the following findings of fact: A. CEQA provides that "public agencies should not approve Projects as proposed if there are feasible alternatives or feasible mitigation measures available which would substantially lessen the significant environmental effects of such Projects[.]" The procedures required by CEQA "are intended to assist public agencies in systematically identifying both the significant effects of proposed Projects and the feasible alternatives or feasible mitigation measures which will avoid or substantially lessen such significant effects" (Ibid.); B. CEQA also provides that "in the event [that] specific economic, social, or other conditions make infeasible such Project alternatives or such mitigation measures, individual Projects may be approved in spite of one or more significant effects." CEQA provides that a public agency has an obligation to balance a variety of public objectives, including economic, environmental, and social factors, and in particular the goal of providing a decent home and satisfying living environment for every Californian. CEQA requires decision -makers to balance the benefits of a proposed Project against its significant unavoidable adverse environmental impacts, and, if the benefits of a proposed Project outweigh the significant unavoidable adverse environmental impacts, the unavoidable adverse environmental impacts may be considered "acceptable" by adopting a Statement of Overriding Considerations. The Statement of Overriding Considerations must set forth the Project benefits or reasons why the lead agency is in favor of approving the Project and must weigh these benefits against the Project's adverse environmental impacts identified in the Final EIR that cannot be mitigated to a less -than -significant level; C. CEQA's mandates and principles are implemented, in part, through the requirement that agencies adopt findings before approving Projects for which EIRs are required. For each significant environmental effect identified in an EIR for a proposed Project, the approving agency must issue a written finding reaching one or more of three permissible conclusions: (1) "[c]hanges or alterations have been required in, or incorporated into, the Project which avoid or substantially lessen the significant environmental effect as identified in the Final EIR," (2) [s]uch changes or alterations are within the responsibility and jurisdiction of another public agency or can and should be adopted by such other agency," or (3) [s]pecific economic, legal, social, technological, or other considerations, including provision of employment opportunities for highly trained workers, make infeasible the mitigation measures or Project alternatives identified in the final EIR." CEQA defines "feasible" to mean capable of being accomplished in a successful manner within a reasonable period of time, taking into account economic, environmental, social, legal and technological factors; D. The concept of "feasibility" also encompasses the question of whether a particular alternative promotes the underlying goals and objectives of a Project. "Feasibility" under CEQA, then, encompasses "desirability" to the extent that desirability is based on a reasonable balancing of the relevant economic, environmental, social, and technological factors; E. CEQA requires that the lead agency exercise its independent judgment in reviewing the adequacy of an EIR, and that the decision of a lead agency in certifying a Final EIR and approving a Project not be predetermined. The City Council has conducted its own review and analysis, and is exercising its independent judgment when acting as herein provided; F. CEQA requires decision -makers to adopt an MMRP for those mitigation measures identified in the Final EIR that would mitigate or avoid each significant impact identified in the EIR, and to incorporate the MMRP, including all mitigation measures, as a condition of Project approval; G. CEQA requires that the responses to comments in the Final EIR demonstrate good faith and a well -reasoned analysis, and not be overly conclusory. In response to several comments received, portions of the Draft EIR have been revised. Although new material has been added to the Draft EIR through preparation of the Final EIR, this new material provides clarification to points and information already included in the Draft EIR, and is not considered to be significant new information or a substantial change to the Draft EIR or to the Project that would necessitate recirculation; and H. State CEQA Guidelines note that State courts have held that the purpose of an EIR is to inform other governmental agencies and the public generally of the environmental impacts of a proposed Project. CEQA does not require technical perfection or exhaustive treatment of issues in an EIR, but rather adequacy, completeness, and a good -faith effort at full disclosure. SECTION 3. CEQA FINDINGS. The City Council finds that the Final EIR, which consists of the Draft EIR (March 2017), Planning Commission Final EIR (June 2017), and Final EIR (August 2017) for Master Case No. 14-077 (Tentative Tract Map 53074, Conditional Use Permit 14-014, Hillside Development Review 14-001, Ridgeline Alteration Permit 14-001, Minor Use Permit 14-016, and Oak Tree Permit 14-008) identifies and discloses Project -specific impacts and cumulative Project impacts. Environmental impacts identified in the Final EIR, findings, and facts in support of findings are herein incorporated by reference as "CEQA Facts and Findings," referred to as Exhibit A, and identified as follows: A. The Final EIR identifies significant unavoidable adverse impacts of the Project, as set forth in Section 7.0 of Exhibit A. Changes or alterations have been required in, or incorporated into, the Project that will avoid or lessen certain of the Project impacts, but that will not avoid or reduce all of the potential impacts to a less -than -significant level. These remaining significant impacts are balanced against Project benefits and are found to be overridden by the Project benefits, as stated in the Statement of Overriding Considerations in Section 6. B. The Final EIR also identifies significant but mitigated impacts, as set forth in Section 5.3 of Exhibit A. Changes or alterations have been required in, or incorporated into, the Project that will avoid or reduce these potential impacts to a less -than -significant level. C. The Final EIR also identifies less -than -significant impacts, as set forth in Section 5.2 of Exhibit A. D. As issues that are noted in Section 3(C) have no significant environmental impacts and require no mitigation, those issues also will have no contribution to cumulative impacts. E. The MMRP, attached as Exhibit B and herein incorporated by reference, is required to mitigate Project impacts. SECTION 4. CONSIDERATION OF A REASONABLE RANGE OF ALTERNATIVES. Based upon the above recitals and the entire record, including the Sand Canyon Plaza Mixed Use Project Final EIR, oral and written testimony and other evidence received at the public hearings held on the Project and the Final EIR and otherwise, upon studies and investigation made by the City Council, and upon reports and other transmittals from City staff to City Council, the City Council further finds that the Final EIR analyzes a reasonable range of Project alternatives that would feasibly attain most of the basic objectives of the Project, would lessen any of the significant impacts of the Project, and adequately evaluate the comparative merits of each alternative. A. The Project objectives are specified in the Draft Final EIR and in Section 2.2 of Exhibit A. These objectives are used as the basis for comparing the Project alternatives and determining the extent that the objectives would be achieved relative to the proposed Project. Only those impacts found to be significant and unavoidable are relevant in making the final determination of whether an alternative is environmentally superior or inferior to the proposed Project. The Project would result in significant and unavoidable impacts in two environmental issue areas: 1. Air Quality — Regional Operational Emissions and Cumulative Operational Emissions 2. Noise — Construction Noise, Construction Vibration Levels (Human Annoyance), and Cumulative Traffic Noise B. Alternative 1 — No Project Alternative. This alternative is required by the State CEQA Guidelines, and compares the impacts that might occur if the site is left in its present condition with those that would be generated by the proposed Project. Under this alternative, no development or redevelopment would occur beyond what exists today. The No Project Alternative would avoid the significant and unavoidable impacts identified in the Final EIR and most other identified significant impacts, and, therefore, is considered environmentally superior to the Project. This alternative would not attain any of the objectives of the Project. Therefore, this alternative is infeasible and also would not provide any of the Project benefits. C. Alternative 2 — Increased Commercial and Office. This alternative would increase the commercial building area by 29,400 square feet and the office building area by 30,000 square feet. Alternative 2 would also remove 60 units from PA2 and would eliminate the assisted living facility in PAL In comparison to the proposed Project, Alternative 2 would result in similar impacts relative to aesthetics, agriculture and forestry resources, air quality, biological resources, cultural resources, greenhouse gas emissions, hazards and hazardous materials, hydrology and water quality, mineral and energy resources, noise, population and housing, parks and recreation, public services, transportation/traffic, solid waste, wastewater, and water supply. None of the significant unavoidable impacts related to air quality and noise impacts would be reduced or eliminated with Alternative 2. Alternative 2 fully meets 14 objectives, and partially meets the remaining six objectives, as shown in Section 5.5 of Exhibit A. Therefore, this alternative is infeasible because it would not fully satisfy these six Project objectives, and would not provide all of the Project benefits. D. Alternative 3 — Ridgeline Preservation. Approximately 1,200 lineal feet of the City -identified significant ridgeline would be preserved under this Alternative due to the elimination of the northerly portion of PA5. To a lesser extent, the Ridgeline Preservation Alternative would remove 29 dwelling units from PA5. This would also increase open space/landscape areas within the Project area. No other site plan specifics would change. In comparison to the proposed Project, Alternative 3 would result in fewer impacts relative to aesthetics, air quality, and geology and soils. Impacts for the remaining 19 topical areas would be similar under Alternative 3 as those anticipated for the proposed Project. Significant unavoidable impacts related to air quality and noise would be reduced, but not eliminated under Alternative 3. The development anticipated under the Alternative 3 includes the same mix of land uses anticipated for the proposed Project. Alternative 3 fully meets all 20 Project objectives. Alternative 3 is the environmentally superior alternative. Modifications made to the Project during the Planning Commission review have resulted in a revised Project that is substantially consistent with this Alternative. Development on the northern portion of the ridgeline has been eliminated consistent with this Alternative. The primary difference is the revised Project would create a two -acre park on a small portion of the ridgeline that was going to be preserved under this Alternative. This park is considered to be beneficial and an enhancement as compared to Alternative 3. Though this Alternative is the environmentally superior alternative, it would not provide all of the benefits associated with the Project as revised by the Planning Commission, more specifically the inclusion of a private park. Therefore, this Alternative is infeasible. E. Alternative 4 -- Army Corps of Engineers/California Department of Fish and Wildlife Avoidance. Alternative 4 would avoid jurisdictional areas associated with Sand Canyon Wash. Specifically, 7,800 square feet of commercial building area would be eliminated in PA1, 44 units would be eliminated in PA2, 10.1 acres of PA3 would be converted from residential use to open space (removing 122 units), PA4 would be reduced by 42 units, and PA5 would be reduced by 42 units. The above modifications would result in an increase of 22.4 acres of open space. In total, Alternative 4 would remove 250 units when compared to the proposed Project. In comparison to the proposed Project, Alternative 4 would result in greater impacts for land use and planning, and population and housing. Alternative 4 would result in fewer impacts for aesthetics, air quality, biological resources, cultural resources, geology and soils, greenhouse gas emissions, hydrology and water quality, noise, public services, transportation and traffic, solid waste, wastewater, and water supply. Alternative 4 would result in similar impacts for agriculture and forestry resources, and hazards and hazardous materials. Significant unavoidable impacts related to air quality and noise would be reduced, but not eliminated, under Alternative 4. The development anticipated under the Alternative 4 includes the same mix of land uses anticipated for the proposed Project, although with fewer residential units and less non- residential square footage. Alternative 4 partially meets 10 Project objectives, and fully meets the remaining 10 Project objectives, as shown in Section 5.5 of Exhibit A. Therefore, this alternative is infeasible because it would not fully satisfy all of the Project objectives. F. Modification of Project Description Based on Alternatives Discussion. During the Planning Commission consideration of this Project, there were discussions regarding the preservation of the northern portion of the ridgeline. As a result, the Project was modified, as detailed in Section 1, and in a manner substantially consistent with Alternative 3. SECTION 5. FINDINGS FOR CERTIFICATION OF THE FINAL EIR. Based upon the above recitals and the entire record, including, without limitation, the Sand Canyon Plaza Mixed Use Final EIR, oral and written testimony and other evidence received at the public hearings held on the Project and the Final EIR, upon studies and investigation made by the City Council, and upon reports and other transmittals from City staff to the City Council, the City Council finds the following: A. That the Final EIR for the Project is adequate, complete, has been prepared in accordance with CEQA, and should be certified on that basis, B. That the City Council has independently reviewed and considered the Final EIR in reaching its conclusions; C. That the Final EIR was presented and reviewed prior to taking final action to certify the Final EIR and approve the Project; D. That, in accordance with State CEQA Guidelines, the Final EIR includes a description of each potentially significant impact, and rationale for finding that changes or alterations have been required in, or incorporated into, the Project, which avoid or substantially lessen the significant environmental effect, as detailed in Exhibit A attached hereto. The analyses included in the Final EIR to support each conclusion and recommendation therein is hereby incorporated into these findings; E. That, in accordance with Public Resources Code Section 21081, modifications have occurred to the Project to reduce significant effects; F. That, in accordance with Public Resources Code Section 21081 and State CEQA Guidelines, changes and alterations have been required and incorporated into the Project that avoid or substantially lessen its significant environmental effects because feasible mitigation measures, including those in the MMRP, are made conditions of approval for the Project; G. That the Statement of Overriding Considerations identifies and weighs the revised Project's significant impacts that cannot be mitigated to a level below significant against the community benefits from this revised Project, and concludes, based on substantial evidence in the record, that the revised Project's benefits outweigh its unavoidable significant impacts; H. That the Final EIR reflects the decision -maker's independent judgment and analysis; I. That an MMRP has been prepared and is recommended for adoption to enforce the mitigation measures required by the Final EIR and Project approvals; and J. That the documents and other materials which constitute the record of proceedings on which this decision is based are with the Community Development Department, specifically in the custody of the Director of Community Development. SECTION 6. STATEMENT OF OVERRIDING CONSIDERATIONS. Based upon the above recitals and the entire record, including the Final EIR, oral and written testimony and other evidence received at the public hearings held on the Project and the Final EIR and otherwise, upon studies and investigation made by the City Council, and upon reports and other transmittals from City staff to the City Council, the City Council finds that there is substantial evidence that supports the conclusion that the Project will 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. A. Significant, unavoidable impacts include the following, as further described in Exhibit A attached hereto and incorporated herein by this reference: • Air Quality — Regional Operational Emissions and Cumulative Operational Emissions Noise — Construction Noise, Construction Vibration Levels (Human Annoyance), and Cumulative Traffic Noise B. The benefits of the Project outweigh its significant unavoidable impacts that cannot be mitigated to a level below significant. These benefits are listed in Section 7.3 of Exhibit A of this Resolution. SECTION 7. The City Council has reviewed and considered the Final EIR, and hereby determines that it is adequate and in compliance with CEQA. In compliance with Public Resources Code Section 12081 and State CEQA Guidelines Section 15093, the City Council has considered the Project benefits as balanced against its unavoidable adverse environmental effects, and hereby determines that the benefits outweigh the unavoidable adverse environmental effects; therefore, the City Council determines that the unavoidable adverse environmental effects are considered acceptable. The City Council hereby certifies the Final EIR and associated documents, and adopts the MMRP and Statement of Overriding Considerations. SECTION 8.

The Statement of Facts and Findings is the first set of findings where the Lead Agency identifies the significant impacts, presents facts supporting the conclusions reached in the analysis, makes one or more of three potential findings for each impact, and explains the reasoning behind the agency's findings. The following statement of facts and findings has been prepared in accordance with the California Environmental Quality Act (CEQA) and Public Resources Code Section 21081. CEQA Guidelines Section 15091 (a) provides that: No public agency shall approve or carry out a project for which an EIR has been certified which identifies one or more significant environmental effects of the project unless the public agency makes one, or more written findings for each of those significant effects, accompanied by a brief explanation of the rationale for each finding. The three finding categories available for the Statement of Facts and Findings pursuant to CEQA Guidelines Section 15091. Changes or alterations have been required in, or incorporated into, the project which avoid or substantially lessen the significant environmental effect as identified in the Final EIR. 2. Such changes or alterations are within the responsibility and jurisdiction of another public agency and not the agency making the finding. Such changes have been adopted by such other agency or can and should be adopted by such other agency. 3. Specific economic, legal, social, technological, or other considerations, including provision of employment opportunities for highly trained workers, make infeasible the mitigation measures or project alternatives identified in the Final EIR, The Statement of Overriding Considerations is the second set of findings. Where a project would cause unavoidable significant impacts, the Lead Agency may still approve the project where its benefits outweigh the adverse impacts. Further, as provided in the Statement of Overriding Considerations, the Lead Agency sets forth specific reasoning by which benefits are balanced against effects, and approves the project. These findings in the Statement of Overriding Considerations are presented in Section 7.0. September 2017 Statement of Facts and Findings and Statement of Overriding Considerations forthe Sand Canyon Plaza Mixed -Use Project Final Environmental Impact Report The City of Santa Clarita (City), the CEQA Lead Agency, finds and declares that the Sand Canyon Plaza Mixed Use Project Final Environmental Impact Report (EIR) has been completed in compliance with CEQA and the CEQA Guidelines. The City Council finds and certifies that the EIR was reviewed and information contained in the EIR was considered prior to approving the Sand Canyon Plaza Mixed Use Project herein referred to as the "project." Based upon its review of the EIR, the City Council finds that the EIR is an adequate assessment of the potentially significant environmental impacts of the proposed project, represents the independent judgment of the City, and sets forth an adequate range of alternatives to this project. The Final EIR (August 2017) is composed of the following elements: • Sand Canyon Plaza Mixed Use Project Draft Environmental Impact Report (dated March 2017) • Planning Commission Final EIR (June 2017) • Draft EIR Technical Appendices • Mitigation Monitoring and Reporting Program • A list of persons commenting on the Draft EIR, Comments, and Responses • Errata for Final EIR September 2017 Statement of Facts and Findings and Statement of Overriding Considerations forthe Sand Canyon Plaza Mixed -Use Project Final Environmental Impact Report 2.0 PROJECT SUMMARY 2.1 DESCRIPTION OF PROJECT PROPOSED FOR APPROVAL DESCRIPTION OF PROJECT The following discussion describes the types and amounts of new land uses as revised by the Planning Commission and the infrastructure improvements necessary to construct the development. Table 1 below summarizes the statistics associated with the project.

Also proposed on the Project site are 580 residential units comprising 461 multi -family units (including up to 312 apartment units and 149 attached townhomes) and 119 single-family detached condominiums. If approval of the Project is granted, Project conditions of approval would permit modifications to building locations, building footprints, and product types. The approximately 87 -acre project site is divided into five Planning Areas (PA), described below. Planning Area 1 (Commercial) — Approximately 145,000 square feet of commercial/residential floor space including 60,000 square feet of commercial (retail and restaurants) and an 85,000 -square -foot assisted living facility (up to 140 beds) on approximately 9.6 acres. Planning Area 1 is located at the northeast intersection of Sand Canyon Road and Soledad Canyon Road. PA 1 also includes a water quality/water feature located at the southwest corner of the project site. Consistent with the requirements of the September 2017 Statement of Facts and Findings and Statement of Overriding Considerations forthe Sand Canyon Plaza Mixed -Use Project Final Environmental Impact Report MXN zone, the maximum building height in PA -1 would be 50 feet (assisted living facility). The remaining commercial buildings in PA -1 would range in height from 20 to 35 feet. Access to PA -1 would occur via Soledad Canyon Road and "A" Drive (left in/right in and right out) and Sand Canyon Road and "A" Drive (left in/right in and right out). Up to 415 parking spaces would be provided for the retail commercial area contingent upon final uses and square footage, which includes 151 surface spaces and 264 spaces in a parking structure. Of the total 415 parking spaces, up to 70 spaces would be provided for the assisted living facility contingent upon the final bed count. Planning Area 2 (Multi -Family Attached) — 312 multi -family units (intended to be rental units) and required parking per the MXN zone requirements would be developed on 12.2 acres. One private recreational area with a pool, internal drive aisles, water quality improvements, and other open areas would be provided within PA -2. The maximum building height in PA -2 is 50 feet. Access to PA -2 would be from Sand Canyon Road via "A" and "B" Drives. Approximately 1 acre of the existing Sand Canyon Road right-of-way would be vacated by the City and included in PA -2, as it would no longer be needed for roadway purposes. Planning Area 2 is located directly north of PA 1 along Sand Canyon Road. Planning Area 3 (Multi -Family Attached Townhomes) — 149 townhomes with required parking (per the MXN zone requirements) on approximately 10.3 acres. Water quality improvements, internal drive aisles, trails and other open areas would be provided within PA -3. The maximum building height in PA 3 is 40 feet. Access to PA -3 would be from Sand Canyon Road via "B", "C" and "D" Drives. Planning Area 3 is located north of Planning Area 2 along Sand Canyon Road. Planning Area 4 (Single -Family Detached Condominiums) — 71 units with required parking (per MXN and UR -3 zone requirements) on approximately 7.3 acres. Internal drive aisles, water quality improvements, trails, and other open areas would be provided within PA -4. The two -acre private recreational area located in PA -5 would also service PA 4. Access to PA -4 would be from Sand Canyon Road via "B," "C," and "D" Drives. Planning Area 4 is located in the central portion of the project site north and east of Planning Area 2 and is depicted in Figure 3-12, Planning Area 4. Planning Area 5 (Single -Family Detached Condominiums) — 48 units with required parking (per MXN and UR -3 zone requirements) on approximately 6.3 acres. A two -acre private recreational area, internal drive aisles, water quality improvements, trails and other open areas would be provided within PA -5. Access to PA -5 would be from Sand Canyon Road via "B", "C" and "D" Drives. Planning Area 5 is located in the eastern and northern portions of the project site. The project includes a total of 580 residential units (replacing the existing 123 mobile homes), 60,000 square feet of retail commercial uses, and an 85,000 -square -foot assisted living facility. September 2017 Statement of Facts and Findings and Statement of Overriding Considerations for the Sand Canyon Plaza Mixed -Use Project Final Environmental Impact Report Project Design Features The following Project Design Features have been incorporated into the project. PDF -1 Landscape irrigation plans shall include drought -tolerant and native plants (consistent with General Plan EIR Mitigation Measures 3.13-6 and 3.13-11). PDF -2 Landscape irrigation plans shall incorporate low -water -use devises (such as ET controllers and drip irrigation), to the extent feasible (consistent with General Plan EIR Mitigation Measures 3.13-6 and 3.13-11). PDF -3 Water conservation measures as required by the State of California shall be incorporated into all irrigation systems. PDF -4 The Project Applicant, or responsible party, shall require the installation of low -flow fixtures in all residential units, which may include but are not limited to water conserving shower heads, toilets, waterless urinals and motion -sensor faucets, and encourage use of such fixtures in building retrofits as appropriate (consistent with General Plan EIR Mitigation Measures 3.13-7 and 3.13-13). PDF -5 Prior to commencement of use, all uses of recycled water shall be reviewed and approved by the State of California Health and Welfare Agency, Department of Health Services. PDF -6 Prior to the issuance of building permits, the Project Applicant, or responsible party, shall finance the expansion costs of water service extension to the subdivision through the payment of connection fees to the appropriate water agency(ies). PDF -7 For sensitive uses within 500 feet of the SR -14 Freeway, incorporate air filtration systems with filters meeting or exceeding the ASHRAE 52.2 Minimum Efficiency Reporting Value (MERV) of 11. MERV 11 filters are effective in improving indoor air quality as compared to lower efficiency filters for PM10 and PM2.5. PDF -8 Locate open space areas associated with sensitive uses (e.g., courtyards, patios, balconies) as far from the freeway sources as possible. PDF -9 Plant vegetation between sensitive receptors and freeway sources. PDF -10 Utilize site plan design that minimizes operable windows and building entries along the freeway. PDF -11 For sensitive uses within 500 feet of the SR -14 Freeway, utilize options for mechanical and ventilation systems (i.e., supply or exhaust based systems). If a supply -based system is proposed (i.e., actively bringing outside air through intake ducts), consider locating intakes as far from the freeway sources as possible. PDF -12 The Applicant shall implement all control measures required and/or recommended by the SCAQMD (i.e., Rules 403, 1108, and 1113), including but not limited to the following: September 2017 Statement of Facts and Findings and Statement of Overriding Considerations forthe Sand Canyon Plaza Mixed -Use Project Final Environmental Impact Report Use watering to control dust generation during demolition of structures or break- up of pavement; • Water active grading areas and unpaved surfaces at least three times daily; a Cover stockpiles with tarps or apply non-toxic chemical soil binders; • Limit vehicle speed on unpaved roads to 15 miles per hour; Sweep daily (with water sweepers) all paved construction parking areas and staging areas; • Provide daily clean-up of mud and dirt carried onto paved streets from the Project site; • Suspend excavation and grading activity when winds (instantaneous gusts) exceed 15 miles per hour over a 30 -minute period or more; and • An information sign shall be posted at the entrance to the 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. Grading Demolition/Site Clearin The project would require demolition of the remaining mobile home units and site clearing, In addition to the removal of the mobile homes, demolition would include the removal of asphalt, concrete, other ancillary structures to the existing mobile home park, trees, fences, and other existing debris. Grading/Foundation The project would include grading approximately 2.1 million cubic yards of cut and fill balanced on-site. Additional remedial grading (approximately 850,000 cubic yards) would be necessary to accommodate site development. Mobility Plan The project provides for non -vehicular modes of transportation in a system of trails, sidewalks and pedestrian pathways commonly known as the Mobility Plan. The Mobility Plan achieves Project Objectives by creating and enhancing opportunities for non -vehicular travel through encouraging pedestrian mobility from the project's residential areas to the commercial uses. Drainage/Water Quality The Drainage and Water Quality Plan incorporates methodologies to meet or exceed the ongoing National Pollution Discharge Elimination System (NPDES) permit requirements. The plan includes a comprehensive series of drainage, flood control and water quality improvements designed for the project. Project Design Features (PDFs) incorporated into the project include site design, source control, treatment control and infiltration. As currently planned, storm water runoff from all developed areas of the project would be routed to bioretention areas, vegetated swales and infiltration treatment control devices. These water September 2017 Statement of Facts and Findings and Statement of Overriding Considerations forthe Sand Canyon Plaza Mixed -Use Project Final Environmental Impact Report quality improvements would be designed to operate off-line, receiving dry weather flows, small storm flows and the initial portion of large storm flows. Conceptual Landscape Plan The conceptual landscape plan focuses primarily on the use of native and drought tolerant trees and plant species to create a natural and vibrant environment. All plant species have been selected due to their ability to thrive in the Santa Clarita climate and their potential to add complexity and texture to the open space/landscaped areas within the project. The use of turf shall be very limited and only used in locations where it would serve for passive or active recreation. The irrigation systems would be designed, installed, operated and maintained in conformance with the State Water Efficient Landscape Ordinance and the City of Santa Clarita Landscaping Standards. The main objective for the irrigation design is to minimize water use and maximize efficiency. These objectives would be met using Smart ET Based controllers, hydro -zoning, moisture sensors, rain shut-off devices, and drip irrigation. Although portions of the native planting areas may receive temporary irrigation, a permanent irrigation system is important for a majority of the landscape areas to comply with the Los Angeles County Fire Department Fuel Modification Guidelines. Local Roadway Circulation and Access The project's roadway network is designed as an orderly extension of the regional circulation patter in the Santa Clarita Valley. The network is designed to integrate modes of travel, accommodate anticipated traffic demands generated by the project and surrounding development and provide roadway improvements that connect the project to SR -14 and the rest of the Valley. Vehicular access to and from the project site is proposed from two existing roadways (Sand Canyon Road and Soledad Canyon Road). More specifically, access to the site would be from: 1) Soledad Canyon Road via "A" Drive; 2) Sand Canyon Road via "A" Drive; 3) Sand Canyon Road via "B" Drive; and 4) Sand Canyon Road via "C" Drive. Sand Canyon Road is a north - south arterial with two lanes between Sierra Highway and Soledad Canyon Road, four lanes between Soledad Canyon Road and SR -14 northbound ramps, and back down to two lanes south of SR -14 northbound ramps. It is designated as a Major Highway between Soledad Canyon Road and Lost Canyon Road, a Secondary Highway between Sierra Highway and Soledad Canyon Road, and a Limited Secondary Highway south of Lost Canyon Road. The project would complete various improvements to Soledad Canyon Road to include widening for roadway purposes. The project would also widen Sand Canyon Road for roadway and trail purposes and construct two single lane roundabouts; one at "B" Drive and Sand Canyon Road and the other at "C" Drive and Sand Canyon Road. Most of Sand Canyon Road would remain at two lanes (one in each direction), with grading of the full right-of-way to potentially accommodate widening if needed in the future. The interior of the project would be served by private roadways. September 2017 Statement of Facts and Findings and Statement of Overriding Considerations forthe Sand Canyon Plaza Mixed -Use Project Final Environmental Impact Report Recreation Two private recreational areas are planned for the Project, including a two -acre private park. At least one of the facilities would contain a pool, a spa, a restroom facility, and a recreation building. Open Space The Project includes 31.4 acres of open space throughout the site, including natural habitat areas along on the northern portion of the ridgeline. PROJECT PHASING The Sand Canyon Plaza Mixed -Use Project would likely be developed in a single phase. Grading and site development would occur site -wide. It is expected that the three residential product types, the commercial area, and various on-site and off-site infrastructure would be constructed at or near the same time. AGREEMENTS, PERMITS, AND APPROVALS The City of Santa Clarita is the Lead Agency for the project and has discretionary authority over the project which includes the following: Tentative Tract Map No. 53074. The Applicant is proposing to subdivide the property to facilitate construction of 580 residential units (119 detached condominium units, 149 attached townhcmes/condominium units, and 312 apartment units), up to 60,000 square feet of commercial uses (retail and restaurants), an 85,000 -square -foot assisted living facility (up to 140 beds), other lots for landscape/open space, private streets, and recreation areas. 2. Conditional Use Permit No. 14-014. The Applicant is requesting approval of a Conditional Use Permit (CUP) to allow for development within a Planned Development (PD) Overlay Zone. Any new proposal for development in a PD Overlay requires the submittal of a Conditional Use Permit, which is intended to provide for additional discretion for previously vacant or underutilized parcels. Additionally, the Applicant is requesting approval of an 85,000 -square -foot assisted living facility with up to 140 beds. A Conditional Use Permit is required to permit the assisted living facility within the MXN zone. 3. Hillside Development Review No, 14-001. The Applicant is requesting approval of a Hillside Development Review Permit to allow development on slopes over 10%. 4. Ridgeline Alteration Permit No. 14-001. The Applicant is requesting approval of a Ridgeline Alteration Permit to allow for development in a Ridgeline Preservation (RP) Overlay Zone, more specifically to allow for development within 100 feet vertically and horizontally of a significant ridgeline. 5. Minor Use Permit No. 14-016. The Applicant is requesting approval of a Minor Use Permit to allow for the commercial floor area ratio (FAR) to be less than the minimum required by the MXN zone. Under the MXN zone requirements, the minimum floor area September 2017 Statement of Facts and Findings and Statement of Overriding Considerations forthe Sand Canyon Plaza Mixed -Use Project Final Environmental Impact Report ratio of commercial uses on the site would be 0.2:1 or 83,635 square feet of commercial floor area. The Applicant is proposing to develop the site with up to 60,000 square feet of commercial uses, which is a floor area ratio of 0.14. 6. Oak Tree Permit No. 14-008. The Applicant is requesting approval of an Oak Tree Permit to allow for removal of two non -heritage oak trees and to permit Project grading to encroach within the protected zone of one heritage oak tree. 2.2 STATEMENT OF OBJECTIVES The Sand Canyon Plaza Mixed Use Project includes the following objectives: Land Use Planning Objectives 1.

The hearing was held at City Hall, 23920 Valencia Boulevard, Santa Clarita, California. September 2017 12 Statement of Facts and Findings and Statement of Overriding Considerations for the Sand Canyon Plaza Mixed -Use Project Final Environmental Impact Report 4.0 INDEPENDENT JUDGMENT AND FINDING The City solicited proposals from independent consultants to prepare the Sand Canyon Plaza Mixed Use Project and EIR. Subsequently, the City selected and retained Tebo Environmental Consulting, Inc. to prepare the Sand Canyon Plaza Mixed -Use Project EIR. Tebo Environmental Consulting, Inc. prepared the EIR under the supervision and direction of the City of Santa Clarita staff. All findings set forth herein are based on substantial evidence in the record as indicated with respect to each specific finding. FINDING: The EIR for the project reflects the City's independent judgment. The City has exercised independent judgment in accordance with Public Resources Code Section 21082.1(c)(3) in retaining its own environmental consultant, and directing the consultant in the preparation of the EIR. The City has independently reviewed and analyzed the EIR and accompanying studies and finds that the report reflects the independent judgment of the City. The City Council has considered all the evidence presented in its consideration of the project and the EIR, including, but not limited to, the Final EIR and its supporting studies, written and oral evidence presented at hearings on the project, and written evidence submitted to the City by individuals, organizations, regulatory agencies, and other entities: On the basis of such evidence the City Council finds that with respect to each environmental impact identified in the review process the impact (1) is less than significant and would not require mitigation; or (2) is potentially significant but would be avoided or reduced to a less than significant level by implementation of identified mitigation measures; or (3) would be significant and not fully mitigatible but would be, to the extent feasible, lessened by implementation of identified mitigation measures. The Final EIR identifies certain significant adverse environmental effects of the project which cannot be avoided or substantially lessened. Prior to approving this project, the City Council will adopt a Statement of Overriding Considerations which finds, based on specific reasons and substantial evidence in the record (as specified in Section 7.0), that certain identified economic, social, or other benefits of the project outweigh such unavoidable adverse environmental effects.

Mitigation Measures: MM Geo -29 Foundation • General: Buildings may be supported on continuous or individual spread footings established in properly compacted fill soils. Foundations and floor slabs should be designed by a structural engineer, in accordance with the minimum requirements of the CBC. • Design Criteria: The recommendations presented in this section are based on the assumption that the proposed structures will have column loads not exceeding approximately 100 kips and continuous foundation loads not exceeding 3 kips per lineal foot. A bearing value of 2,000 pounds per square foot (psfi may be used in the design of spread foundations. This value can be increased by one-third when considering seismic and wind forces. The bearing material shall consist of compacted fill soil. Individual column pads and continuous wall footings shall be designed to meet the minimum width September 2017 30 Statement of Facts and Findings and Statement of Overriding Considerations forthe Sand Canyon Plaza Mixed -Use Project Final Environmental Impact Report and depth requirements as set forth in the CBC. Foundation depths shall be measured from the lowest adjacent final grade. Building Setbacks: Building setbacks for structures located adjacent to either ascending or descending slopes shall be in accordance with the standards set forth in the CBC. All foundation excavations shall be observed and approved by a representative from our firm prior to placement of reinforcing steel. Foundations shall be deepened, where necessary, to prevent surcharge loads from being imposed on adjacent foundations or utilities. Observation of foundation excavations may also be required by the appropriate reviewing governmental agencies. The contractor shall be familiar with the requirements of the governing reviewing agencies. Lateral Design: Lateral restraint at the bases of footings or slabs may be assumed to be the product of the dead load and a coefficient of friction of 0.4. Passive pressure on the faces of footings may also be used to resist lateral forces. A passive pressure of zero at the surface of finished grade, increasing at the rate of 250 psf per foot of depth, to a maximum value of 2,500 psf, may be used at this site. The passive pressure and friction may be combined without reduction when evaluating lateral resistance. Settlement: Provided that the proposed buildings are supported on shallow foundations established in compacted fill soils, as recommended, column loads do not exceed 100 kips, and continuous footings do not exceed 3 kips per lineal foot, it is estimated that the maximum static settlement will be about 0.75 inches. The total static and seismic settlement is estimated to be about 1.5 inches. It is further estimated that static and seismic differential settlements will be less than 1.0 inches of vertical movement across a horizontal distance of 30 feet. RTF&A shall review the foundation loads after plans are developed to verify the applicability of our recommendations to the proposed structures. MM Geo -30 Floor Slab Support • General: Thefloor slab design recommendations presented in this section are based upon the assumption that the soil subgrade in proposed floor slab areas will consist of compacted fill soil and that floor slabs will be subjected to normal loads with no special requirements. Any surficial soils that become dried or disturbed during the course of construction shall be moisture - conditioned and compacted prior to casting the floor slab. Conventional floor slabs may be utilized at the subject development, provided the subgrade soils consist of compacted fill soils with a very low (Expansion Index of 0 to 20) potential for expansion. If the subgrade soils are determined to have an expansion potential in the low or higher range (Expansion Index greater than 21), post -tensioned floor slabs, as indicated below, are recommended. Post - tensioned floor slabs can also be used in soils with a very low potential for expansion. • Conventional Floor Slabs: Conventional slabs -on -grade should be designed per the recommendations of the CBC. However, as a minimum, the building floor slabs should have a nominal thickness of at least 4 inches and should be reinforced with a No. 4 rebar spaced at 16 inches on center, in each direction, or equivalent. Thicker slabs may be required depending on CBC September 2017 31 Statement of Facts and Findings and Statement of Overriding Considerations forthe Sand Canyon Plaza Mixed -Use Project Final Environmental Impact Report requirements, the floor loads, and the structural requirements; we defer to the Project Structural Engineer for design of the floor slabs. Post -Tensioned Floor Slabs: Post -tensioned floor slabs should be designed per the recommendations of the CBC. The design values, presented following this paragraph, assume that the proposed floor slabs will be poured monolithic with continuous perimeter edge footings. Perimeter edge footings should have a minimum depth of 12 inches. Footing depths should be measured from the lowest adjacent grade for perimeter footings or the top of slab for interior footings. • Net Bearing Value: An allowable net bearing value of 2,000 psf may be used for footings with a minimum width of 12 inches and a minimum depth of 12 inches below the top of slab or 12 inches below the lowest adjacent grade. • Coefficient of Friction: 0.75 Passive Pressure: 250 pcf for level ground condition • Modulus of Subgrade Reaction (K): 150 pounds per cubic inch (pci) for a footing width of one foot. For larger footings or floor slabs, this value should be reduced using the following equation: Kr = K where: Kr = Reduced Modulus Value K = Modulus of Subgrade Reaction for a One -Foot -Wide Plate B = Width of Large Footing or Slab • Modulus of Elasticity: 1,000 pounds per square inch (psi) • Edge Moisture Variation Distance: Me (Center Lift): 5.25 feet Me (Edge Lift): 2.5 feet Estimated Differential Movements My (swelling): Low — 0.4; Medium — 0.9 My (shrink): Low — 0.3; Medium — 0.7 Water Vapor: Water vapor transmitted through floor slabs is a common cause of floor covering problems. An impermeable membrane vapor barrier should be installed to reduce excess vapor drive through the floor slab. The function of the impermeable membrane is to reduce the amount of water vapor transmitted through the floor slab. Vapor -related impacts should be expected in areas where a vapor barrier is not installed. Floor slabs shall be underlain by a vapor barrier surrounded by 2 inches of sand above and below it. The membrane should be at least 10 millimeters thick; care shall be taken to preserve the continuity and integrity of the membrane beneath the floor slab. The sand shall be sufficiently moist to remain in place and be stable during construction; however, if the sand above the membrane becomes saturated before placing concrete, the moisture in the sand can become a source of water vapor. Another factor affecting vapor transmission through floor slabs is a high water -to -cement ratio in the concrete used for the floor slab. A high water -to -cement ratio increases the porosity of the concrete, thereby facilitating the transmission of water and water vapor through the slab. The Project Structural Engineer or a concrete mix specialist should provide recommendations for design of concrete for footings and floor slabs in accordance with CBC. MM Geo -31 Retaining Walls September 2017 32 Statement of Facts and Findings and Statement of Overriding Considerations forthe Sand Canyon Plaza Mixed -Use Project Final Environmental Impact Report General: A bearing value of 2,000 psf may be used in the design of retaining wall footings. Backfill placed behind retaining walls shall be compacted to a minimum of 90% of the maximum dry density, as determined by the Soil Compaction Test Method (ASTM Standard D1557). When backfilling, walls should be braced. Heavy compaction equipment shall not be used any closer to the back of the wall than the height of the wall. Soils that have an expansion index in excess of 30 shall not be utilized for backfill behind walls that are greater than 3 feet in height. The backs of retaining walls shall be water -proofed where aesthetics are concerned. Lateral Earth Pressure: Cantilevered retaining walls separate and independent of buildings, where the surface of the backfill is level and the retained height of soils is less than 15 feet, may be designed assuming that drained, nonexpansive soils will exert a lateral pressure equal to that developed by a fluid with a density of 30 pounds per cubic foot (pcf). The indicated pressure assumes that a lateral deflection of up to about 1 % of the wall height is acceptable at the top of the wall. If it is desired to decrease the amount of potential wall deflection, a greater lateral pressure could be used in the wall design. Where the surface of the backfill is inclined at 2:1, it may be assumed that drained soils will exert a lateral pressure equal to that developed by a fluid with a density of 45 pcf. For the design of a rigid wall where rotation and lateral movement are not acceptable, as in the case of buildings, it may be assumed that drained, nonexpansive soils will exert a rectangular lateral pressure with a maximum pressure equal to 22H psf, where "H" is the wall height in feet. The pressure value and distribution may vary significantly when considering wall rigidity and restraining conditions. The structural characteristics of the wall are referred to the Project Structural Engineer. If requested, we can provide additional geotechnical design parameters for specific restrained conditions. In addition to the recommended earth pressure, walls should be designed to resist any lateral surcharges due to nearby buildings, storage, or traffic loads. A drainage system should be provided behind the walls to reduce the potential for development of hydrostatic pressure. If a drainage system is not installed, walls should be designed to resist an additional hydrostatic pressure equal to that developed by a fluid with a density of 55 pcf for the full height of the wall. Seismic Lateral Earth Pressure: The preceding recommended values indicate earth pressures for conventional static loading conditions. Ground shaking associated with earthquakes may cause additional pressure on walls. In addition to the previously mentioned lateral earth pressures, it is recommended that all rigid (building) walls of any height, and cantilevered retaining walls greater than 6 feet in height, be designed to support an additional seismic earth pressure equal to an inverted equivalent fluid pressure of 29 pcf. Density of Backfill: When designing retaining walls to resist over -turning, it can be assumed that compacted, on-site soils will have a density of 125 pcf. Drainage: A drainage system should be provided behind retaining walls, or the walls should be designed to resist hydrostatic pressures. September 2017 33 Statement of Facts and Findings and Statement of Overriding Considerations for the Sand Canyon Plaza Mixed -Use Project Final Environmental Impact Report The drainage system could consist of a 4 -inch -diameter perforated pipe placed 6 inches from the base of the wall, with the perforations down, and connected to an outlet device. The pipe should be sloped at least 1 inch per 50 feet and surrounded on all sides by at least 6 inches of clean gravel. The gravel should be "burrito - wrapped" with filter fabric, such as Mirafi 140N, or equivalent. As an alternative to the gravel and filter fabric, filter material meeting the requirements of LACFCD Designated F-1 Filter Material, and slotted pipe, may be used. The backside of the wall should be water -proofed. • A vertical, 6 -inch -wide gravel chimney drain, or a drainage geocomposite such as Miradrain, should be placed against and behind retaining walls that are higher than 3 feet. The top of the back drain should be capped with 18 inches of on-site soils. • The installed drainage system should be observed by the Geotechnical Consultant of Record prior to backfilling the system. Inspection of the drainage system may also be required by the reviewing governmental agencies. MM Geo -32 Pavement Design: Samples of the on-site soil should be obtained from near final grade elevation in proposed pavement areas, following the grading operations, to perform R -value tests. The R -value test results would be used to prepare pavement section recommendations. The preliminary pavement section recommendations presented below are based on the assumption that the on- site soils have an R -value of at least 20. The final pavement section recommendations could vary depending on the results of the actual R -value tests. We would be pleased to provide pavement section recommendations for alternative Traffic Index values upon request. Traffic Asphalt Thickness (CAB) Base Course Thickness Index (inches) (inches) 4 3 5 6 4 9 8 5 14 Base course material should consist of crushed aggregate base (CAB), as defined by Section 2002.2 of the Standard Specifications for Public Works Construction ("Greenbook"), or crushed miscellaneous base (CMB), as defined by Section 200-2.4 of the Greenbook. Base course material should be compacted to at least 95% of the maximum dry density of that material. Base course material should be purchased from a supplier who will certify that it will meet or exceed the specifications in the Greenbook, as indicated. We could, upon request, perform sieve analysis and sand equivalency tests on material delivered to the site that appears suspect. Additional tests could be performed, upon request, to determine if the material is in compliance with the remainder of the specifications indicated in the Greenbook. The pavement section recommendations presented above are based upon assumed Traffic Index values. RTF&A does not take responsibility for the numerical determination of the Traffic Index values, nor the areas where they apply within the site. September 20`17 34 Statement of Facts and Findings and Statement of Overriding Considerations forthe Sand Canyon Plaza Mixed -Use Project Final Environmental Impact Report MM Geo -33 Seismic Design. The following factors are recommended for seismic force design of structures at the subject site. The parameters were determined using the U.S. Seismic Design Maps at the United States Geological Survey (USGS) Earthquakes Hazard website.

GEO-4 WOULD THE PROJECT 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? Findings Changes or alterations have been required in, or incorporated into, the project which avoid or substantially lessen the significant environmental effect as identified in the Final EIR. Facts in Support of Findings The potential impacts associated with ground failure, landslides, unstable soils, or expansive soils have been eliminated or substantially lessened to a level of less than significant by virtue of the mitigation measures identified in the Final EIR. Mitigation Measures; MM Geo -1 Potential debris flow shall be further evaluated once a 40 -scale rough grading plan has been developed for the Project site. Appropriate mitigation measures can be provided for any additional debris flow areas identified on the rough grading plan. September 2017 35 Statement of Facts and Findings and Statement of Overriding Considerations forthe Sand Canyon Plaza Mixed -Use Project Final Environmental Impact Report MM Geo -2 Cut Slope CS -3: Bedrock shall be eliminated during removals within the adjacent canyons and the slope grades re-established as a 25 -foot -wide, 3 -foot - deep stability fill slope. The stability fill slope should be constructed with backdrains in accordance with the recommendations presented in the "Conclusions and Recommendations" section of the RTF&A report, and as shown on the Stability Fill Details for Grossly Stable Slopes, presented as Figure 4 (Frankian Study). MM Geo -3 Cut Slope CS -6 shall be constructed entirely as a 20 -foot -wide, 3 -foot -deep stability fill slope after landslide removal. MM Geo -4 Cut Slope CS -7: Bedrock shall be eliminated during the removals within the adjacent canyons and the slope grades reestablished as a 25 -foot -wide, 3 -foot - deep stability fill slope. MM Geo -5 Cut Slope CS -8: Bedrock shall be eliminated during the removals within the adjacent canyons and the slope grades reestablished as a 25 -foot -wide, 3 -foot - deep stability fill slope. MM Geo -6 Cut Slope CS -11: A small canyon is situated in the central portion of Cut Slope CS 11, below future Lot Nos. 19 and 20. The removals as part of the canyon cleanout in this area, and eventual fill placement, shall extend to the bottom of the cut slope at "D" Drive to eliminate a potential fill -over -cut condition. MM Geo -7 Site Preparation Requirements; • Prior to performing earthwork, the existing vegetation and any deleterious debris should be removed from the site. • All unsuitable soils in the areas of grading that are receiving fill should be removed to competent bedrock materials and replaced with engineered fill. • The depth of removal and recompaction of unsuitable soils is noted on the Geotechnical Map. Any fill required to raise the site grades should be properly compacted. Removal of the exposed natural soils should extend to at least the depths indicated on the Site Geology Map (Figure 4.6-1). MM Geo -8 Removal Depth Requirements: The required depth of removal and recompaction of the natural soils is indicated on the Geotechnical Map. • Deeper removals will be required if disturbed or unsuitable soils are encountered. • After excavation of the upper natural soils on hillsides and in canyons, further excavation should be performed, if necessary, to remove slope wash or other unsuitable soils. • The Geotechnical Consultant of Record may require that additional shallow excavations be made periodically in the exposed bottom to determine that sufficient removals have been made prior to recompacting the soil in-place. Deeper removals may be recommended by RTF&A, based on observed field conditions during grading. • During grading operations, the removal depths should be observed by a representative of RTF&A and surveyed by the Project Civil Engineer for September 2017 36 Statement of Facts and Findings and Statement of Overriding Considerations forthe Sand Canyon Plaza Mixed -Use Project Final Environmental Impact Report conformance with the recommended removal depths shown on the grading plan (Figure 4.6-1). MM Geo -9 Fill Material Requirements: The on-site soils, less any debris or organic matter, may be used in the required fills. • Any expansive clays should be mixed with nonexpansive soils to result in a mixture having an expansion index less than 30 if they are to be placed within the upper 8 feet of the proposed rough grades. • Rocks or hard fragments larger than 8 inches may not be placed in the fill without special treatment. Rocks or hard fragments larger than 4 inches shall not be clustered or compose more than 25% by weight of any portion of the fill or a lift. Soils containing more than 25% rock or hard fragments larger than 4 inches must be removed or crushed with successive passes (e.g., with a sheepsfoot roller) until rock or hard fragments larger than 4 inches constitute less than 25% of the fill or lift. MM Geo -10 Oversized Material Requirements: • Rocks or material greater than 8 inches in diameter, but not exceeding 4 feet in largest dimension, shall be considered oversized rock. The oversized rocks can be incorporated into deep fills where designated by the Geotechnical Consultant of Record. Rocks should be placed in the lower portions of the fill and should not be placed within the upper 10 feet of compacted fill, or nearer than 15 feet to the surface of any fill slope. Windrows should be excluded from areas of proposed utilities, pools, and other types of future underground improvements. Additional costs and construction difficulties should be anticipated if future improvements are located in areas where there will be conflicts with existing windrows. • Rocks between 8 inches and 4 feet in diameter shall be placed in windrows or shallow trenches located so that equipment can build up and compact fill on both sides. The width of the windrows shall not exceed 4 feet. The windrows should be staggered vertically so that one windrow is not placed directly above the windrow immediately below. • Rock greater than one foot in diameter shall not exceed 30% of the volume of the windrows. Granular fill shall be placed on the windrow, and enough water should be applied so that soil can be flooded into the voids. Fill should be placed along the sides of the windrows and compacted as thoroughly as possible. After the fill has been brought to the top of the rock windrow, additional granular fill should be placed and flooded into the voids. Flooding is not permitted in fill soils placed more than 1 foot above the top of the windrowed rocks. • Where utility lines or pipelines are to be located at depths greater than 15 feet, rock shall be excluded in that area. Excess rock that cannot be included in the fill, or that exceeds 4 feet in diameter, should be stockpiled for export or used for landscaping purposes. • The oversized material recommendations presented in this report provide for the geotechnical consultant to coordinate with the grading contractor to develop a procedure for construction of compacted fills that have a satisfactory fill performance for the intended use of the fill. It should be understood that it is not feasible and/or cost effective to eliminate all September 2017 37 Statement of Facts and Findings and Statement of Overriding Considerations for the Sand Canyon Plaza Mixed -Use Project Final Environmental Impact Report oversized material from constructed fills as part of a conventional grading operation. The exclusion of all oversized material is not necessary for satisfactory fill performance on the majority of projects. MM Geo -11 Compaction Requirements: After the site is cleared and excavated as recommended, the exposed soils should be carefully observed for the removal of all unsuitable material. Next, the exposed subgrade soils should be scarified to a depth of at least 6 inches, brought to above optimum moisture content, and rolled with heavy compaction equipment. The upper 6 inches of exposed soils should be compacted to at least 90% of the maximum dry density obtainable by the ASTM D1557 Method of Compaction. After compacting the exposed subgrade soils, all required fills should be placed in loose lifts, not more than 8 inches in thickness, and compacted to at least 90% of their maximum density. For fills placed at depths greater than 40 feet below proposed finish grade, a minimum compaction of 93% of the maximum dry density is required. The moisture content of the fill soils at the time of compaction should be above the optimum moisture content. Compacted fill should not be allowed to dry out before subsequent lifts are placed. Rough grades should be sloped so as not to direct water flow over slope faces. Finished exterior grades should be sloped to drain away from building areas to prevent ponding of water adjacent to foundations. MM Geo -12 Shrinkage and Bulking Requirements: Shrinkage of about 10% to 15% is estimated for the on-site natural alluvial soils when removed and placed as compacted fill. A bulking value of about 3% to 10% is estimated for materials generated from Mint Canyon Formation bedrock cut areas for use as compacted fill. The actual shrinkage and bulking will depend upon the relative compaction obtained by the contractor during grading operations and would be expected to change on a daily basis. MM Geo -13 Permanent Slope Requirements: Permanent cut and fill slopes may be inclined at 2:1 or flatter. The current site plan indicates that the steepest slope to be constructed at the site during grading will be 2:1. MM Geo -14 Proposed Cut Slope Requirements: Cut slopes proposed for the rough grading of the Project site have been designated as shown on the Geotechnical Map. Each cut slope is discussed with specific recommendations presented below. All grading should conform to the minimum recommendations presented in this report. If these slopes are modified from those that are discussed in this report, the modifications should be reviewed by RTF&A to ascertain the applicability of our recommendations. MM Geo -15 Fill Slope Requirements: • Where the toe of a fill slope terminates on natural, fill, or cut materials, a keyway is required at the toe of the fill slope. The fill slope keyway should be a minimum width of 12 feet, be founded within competent material, and September 2017 38 Statement of Facts and Findings and Statement of overriding Considerations for the Sand Canyon Plaza Mixed -Use Project Final Environmental Impact Report extend a horizontal distance beyond the toe of the fill to the depth of the keyway. The keyway should be sloped back at a minimum gradient of 2% into the slope. The width of fill slopes shall be no less than 8 feet, and under no circumstances should the fill widths be less than what the compaction equipment being used can fully compact. Benches should be cut into the existing slope to bind the fill to the slope. Benches should be step-like in profile, with each bench not less than 4 feet in height and established in competent material. Compressible or other unsuitable soils should be removed from the slope prior to benching. Competent material is defined as being essentially free of loose soil, heavy fracturing, or erosion -prone material and is established by the Geotechnical Consultant of Record during grading. Where the top or toe of a fill slope terminates on a natural or cut slope and the natural or cut slope is steeper than a gradient of 3:1, a drainage terrace with a width of at least 6 feet is recommended along the contact. As an alternative, the natural or cut portion of the slope can be excavated and reconstructed as a stability fill slope to provide an all -fill slope condition. Where the contact between the face of the fill slope and the face of a lower natural or cut slope is inclined at 45 degrees or steeper, a drainage terrace would not be required. When constructing fill slopes, the grading contractor shall avoid spillage of loose material down the face of the slope during the dumping and rolling operations. Preferably, the incoming load shall be dumped behind the face of the slope and bladed into place. After a maximum of 4 feet of compacted fill has been placed, the contractor shall backroll the outer face of the slope by backing the tamping roller over the top of the slope, thoroughly covering all of the slope surface with overlapping passes of the roller. The foregoing should be repeated after the placement of each 4 -foot thickness of fill. As an alternative, the fill slope can be overbuilt and the slope cut back to expose a compacted core. If the required compaction is not obtained on the fill slope, additional rolling will be required prior to placement of additional fill, or the slope shall be overbuilt and cut back to expose the compacted core. MM Geo -16 Stability Fill Requirements: Stability fills have been recommended for several of the cut slopes on-site, as discussed in the "Slope Stability" section of this report. The stability fill slopes should be constructed in accordance with Stability Fill Details for Grossly Stable Slopes (Figure 4), Frankian study. Backdrains should be installed at the backcut of the stability fill as recommended below in Mitigation Measures MM Geo -17 and MM Geo -18. MM Geo -17 Subdrain Requirements; • Canyon subdrains are recommended to intercept and remove groundwater within canyon fill areas. All subdrains should extend up -canyon, with the drain inlet carried to within 15 feet of final pad grade. The approximate locations for recommended subdrains are shown on Figure 4.6-1, Site Geology Map. Specific subdrain locations should be determined in the field during grading operations. The subdrains should be surveyed by the Project Surveyor to establish line and grade during construction, and for future September 2017 39 Statement of Facts and Findings and Statement of Overriding Considerations forthe Sand Canyon Plaza Mixed -Use Project Final Environmental Impact Report location reference. Subdrain and backdrain excavations should be observed by the Geotechnical Consultant. The subdrains should be installed in accordance with the manufacturer's specifications. A minimum 2% gradient is to be maintained in the subdrain pipes and the pipe shall have at least eight uniformly spaced narrow slots per foot. The width of the slots should not exceed one -sixteenth of an inch. If PVC pipe with drilled perforations is utilized, the diameter of the holes should not exceed three-eighths of an inch if gravel and filter fabric is used, or one- eighth inch -diameter perforations if Los Angeles County Flood Control District (LACFCD) Designation F-1 Filter Material is used. There should be at least eight uniformly spaced sets of two perforations per lineal foot of pipe. When constructing the subdrain, the pipe should be placed so that the drilled perforations are positioned on the bottom half of the pipe. The upstream end of subdrains should be capped. The final 20 feet of pipe at the downstream end of canyon, stabilization, buttress, and side hill fills shall not be slotted or perforated. Provisions should be made at all times during construction to prevent damage to the subdrain from construction equipment, and to prevent soils from being washed into an exposed subdrain by surface waters. For runs up to 500 feet, subdrains for the bottom of canyon fills should consist of at least 6 -inch -diameter pipe. For runs of 500 to 1,500 feet, 8 -inch - diameter pipe shall be used. For runs over 1,500 feet, 10 -inch -diameter pipe shall be used. Canyon subdrains may be installed in a rectangular trench excavated to expose competent material and shall be approved by the Geotechnical Consultant. The subdrains should be surrounded by at least 3 cubic feet per lineal foot of granular filter material and there should be at least 6 inches of compacted granular filter material or gravel on all sides of the pipe. The granular filter material for subdrains should meet the F1 material criteria, or have a gradation approved by the Geotechnical Consultant prior to placement. As an alternative to the granular filter material, three -quarter - inch -diameter gravel may be placed around the pipe. The gravel should be separated from the surrounding soils by a filter fabric such as Mirafi 140N, or equivalent, wrapped around the gravel ("burrito wrapped"). MM Geo -18 Backdrains Requirements: Backdrains are required for all stability fills or buttress fills. • Backdrains shall consist of 4 -inch -diameter perforated or slotted pipe. • The vertical spacing of the backdrains shall be a maximum of 15 feet, with a horizontal spacing of 100 feet. • Backdrain outlets shall consist of non -perforated pipe. • The backdrain gradient shall be at least 2% to the discharge end. • The exact location of the backdrains shall be determined in the field by the Geotechnical Consultant after the backcut has been made, so that it can be best positioned to intercept potential seepage. MM Geo -19 Surface Drainage Requirements: September 2017 40 Statement of Facts and Findings and Statement of Overriding Considerations forthe Sand Canyon Plaza Mixed -Use Project Final Environmental Impact Report All surface drainage shall be directed away from proposed structures through non-erosive devices. The ponding of water must not be allowed, especially adjacent to foundations. The pad gradients shall not slope toward any descending slopes in order to reduce the potential for surficial erosion. Water that flows towards slopes shall be conducted to appropriate discharge locations via non -erodible drainage devices. Drainage devices, including drainage terraces on graded slopes shall be inspected periodically and kept clear of debris. Drainage and erosion control shall be designed in accordance with the standards set forth in the CBC. Any modification of the grades of building pads, parking areas, etc., could adversely affect drainage at the site. Future landscaping, construction of walkways, planters and walls, etc. must never modify site drainage unless additional measures to enhance drainage (e.g., area drains, additional grading) are designed and constructed in accordance with the applicable City of Santa Clarita. MM Geo -20 Erosion Protection Requirements • To reduce the potential for erosion, all permanent cut -and -fill slopes on-site should be seeded or planted with lightweight, deep -rooting, drought -resistant vegetation. A landscaping expert should be consulted for ground cover recommendations. Excessive landscape irrigation or leakage from irrigation lines can cause localized slope failures. Therefore, irrigation systems for slope vegetation should be designed and maintained to minimize leakage onto graded slopes. If automatic sprinkler systems are used, they should be adjusted for seasonal variations in rainfall. Vegetation on natural slopes should remain natural and not be landscaped or irrigated in the same manner as graded slopes. • Rodent burrows are known to provide direct conduits for water flow that can decrease slope stability. Therefore, to maintain the integrity of graded slopes, a rodent abatement program shall be instituted. • Even with the implementation of these recommendations, it is not possible to eliminate erosion within hillside developments. Removal of debris from drainage devices, slope maintenance, and landscaping shall be required, especially after periods of heavy rainfall. MM Geo -21 General Grading Requirements • All fills, unless otherwise specifically designed, shall be compacted to at least 90% of the maximum dry unit weight as determined by the ASTM D1557 Method of Soil Compaction. • No fill shall be placed until the area to receive the fill has been adequately prepared, and subsequently approved by the Geotechnical Consultant of Record or his representative. • Fill soils should be kept free of debris and organic material. • Rocks or hard fragments larger than 8 inches may not be placed in the fill without approval of the Geotechnical Consultant of Record or his representative, and in a manner specified for each occurrence. • Bedrock fragments larger than 8 inches, or fill soils containing greater than 25% of bedrock fragments larger than 4 inches in diameter, must be September 2017 41 Statement of Facts and Findings and Statement of Overriding Considerations for the Sand Canyon Plaza Mixed -Use Project Final Environmental Impact Report removed or processed using successive passes of a sheepsfoot compactor until rock fragments constitute less than 25% of the fill material. • The fill material shall be placed in layers which, when compacted, shall not exceed 8 inches per layer. Each layer shall be spread evenly and shall be mixed thoroughly during the spreading to ensure uniformity of material and moisture. When moisture content of the fill material is too low to obtain adequate compaction, water shall be added and thoroughly dispersed until the soil is approximately 2% to 4% above optimum moisture content. - When the moisture content of the fill material is too high to obtain adequate compaction, the fill material shall be aerated by blading, or other satisfactory methods, until the soil is approximately 2% to 4% above optimum moisture content. Fill and cut slopes shall not be constructed at gradients steeper than 2:1 (horizontal:vertical). MM Geo -22 Grading Observation, Construction observation shall be made by the Geotechnical Consultant of Record during any grading activities within the Project site, to verify the findings within this report. Additional recommendations may be required for landfill design based on conditions uncovered during grading. MM Geo -23 Temporary Excavation. Based on review of the subject plans, it does not appear that significant temporary excavations will be required during the construction of the proposed development. However, the following recommendations are applicable in areas where excavations are to be made. Temporary excavations are not expected to stand vertically in cuts that exceed 4 feet in height. Temporary excavations in excess of 4 feet may be sloped at a gradient of %:1, to a maximum height of 12 feet in favorably oriented Mint Canyon Formation or Terrace Deposits. Temporary slopes within alluvial soils and slopes greater than 12 feet may be sloped at gradients of 1:1. "Temporary" means a period not exceeding 60 days. All regulations of State or Federal OSHA shall be followed. If excavations are made during the rainy season (normally from November through April), particular care shall be taken to protect slopes against erosion. Measures to help mitigate erosion, such as the installation of berms, plastic sheeting, or other devices, may be warranted. Surface water shall be prevented from flowing over or ponding at the top of excavations. MM Geo -24 Expansive Bedrock. It is anticipated that bedrock materials exposed at pad grade may contain expansive claystone beds that could cause differential expansion. Therefore, within building areas at locations where expansive bedrock units are exposed at pad grade, it is recommended that the bedrock be removed and recompacted to a depth at least 8 feet below the proposed final pad elevations or 5 feet below the bottom of proposed footings, whichever is greater. It is also recommended that the bedrock be removed and recompacted to a depth at least 3 feet below proposed soil subgrade in exposed bedrock areas receiving pavement or hardscape improvements. The soils generated by these over - September 2017 42 Statement of Facts and Findings and Statement of Overriding Considerations forthe Sand Canyon Plaza Mixed -Use Project Final Environmental Impact Report excavations should be mixed with nonexpansive soils to yield a relatively nonexpansive mixture. If the resulting fill soil is still expansive, special construction techniques, such as pad subgrade saturation or post -tensioned slabs, may be required to reduce the potential for expansive soil—related distress. MM Geo -25 Transition Lots. Proposed building pads located in a cut and fill transition zone may experience cracking and movement of the footings and slab due to differing compressibility of the fill, as compared to the bedrock material. To reduce the potential for cracking and differential settlement, the portion of the lot in cut bedrock or terrace deposits should be aver -excavated to a depth at least 5 feet below the proposed finished pad elevation or 3 feet below the bottom of proposed footings, whichever is greater. The over -excavation shall extend at least 5 feet laterally beyond the building limits. Where removal and recompaction for potentially expansive soils or bedrock is also required that the 8 -foot removals be performed as described in the "Expansive Bedrock" section of the RTF&A 2015 report. MM Geo -26 The applicability of the preliminary recommendations for foundation and retaining wall design should be confirmed at the completion of grading. MM Geo -27 Paving studies and soil corrosivity tests should be performed at the completion of rough grading, to develop detailed recommendations for protection of utilities and structures and for construction of the proposed roads.

The project's regional operational air quality emissions associated with area sources, energy demand, and mobile sources (motor vehicles) would exceed the regional thresholds of significance set by the SCAQMD for ROG and NOx during the summertime and the wintertime. Findings Changes or alterations have been required in, or incorporated into, the project that avoid or substantially lessen the significant environmental effect as identified in the Final EIR. 2. Pursuant to CEQA Guidelines Section 15091 (a)(3), specific economic, legal, social, technological, or other considerations, including provision of employment opportunities for highly trained workers, make infeasible the mitigation measures or project alternatives identified in the EIR. Facts in Support of Findings The net increase in regional operational emissions generated by the project would exceed the regional thresholds of significance set by the SCAQMD for ROG and NOx during the summertime and the wintertime. These emissions are primarily due to motor vehicles and area source emissions associated with the operation of a relatively high number of proposed residential uses. These emissions are typical for a mixed-use commercial and residential project of this size. Impacts associated with project implementation have been reduced to the extent feasible. There are no feasible mitigation measures that would reduce ROG or NOx emissions; thus, the impacts would constitute a significant and unavoidable impact. Mitigation Measures: MM AQ -1 The Project Applicant, or designee, shall require that all commercial -related landscaping activities utilize electric lawn mowers and electric leaf blowers to the extent feasible. Cumulative Operational Air Emissions. The project's cumulative operational air quality emissions associated with area sources, energy demand, and mobile sources (motor vehicles) would exceed the regional thresholds of significance set by the SCAQMD for ROG and NOX. Findings Changes or alterations have been required in, or incorporated into, the project that avoid or substantially lessen the significant environmental effect as identified in the Final EIR. 2. Pursuant to CEQA Guidelines Section 15091 (a)(3), specific economic, legal, social, technological, or other considerations, including provision of employment opportunities for highly trained workers, make infeasible the mitigation measures or project alternatives identified in the EIR. September 2017 60 Statement of Facts and Findings and Statement of Overriding Considerations forthe Sand Canyon Plaza Mixed -Use Project Final Environmental Impact Report September 2017 61 Statement of Facts and Findings and Statement of Overriding Considerations forthe Sand Canyon Plaza Mixed -Use Project Final Environmental Impact Report Facts in Support of Findings Due to the non -attainment status of 03, PM10, and PM2.5, the generation of daily operational emissions associated with cumulative development would result in a cumulative significant impact associated with the cumulative net increase of any criteria pollutant for which the region is in non -attainment. With respect to operational emissions, the SCAQMD has indicated that if an individual project results in air emissions of criteria pollutants (CO, ROG, NOX, SOX, PM10, and PM2.5) that exceed the SCAQMD-recommended daily thresholds for project -specific impacts, then it would also result in a cumulatively considerable net increase of these criteria pollutants for which the project region is in non -attainment under an applicable federal or state ambient air quality standard. As discussed previously, the operational emissions associated with the project would exceed the established SCAQMD thresholds for ROG and NOX during the operation of the Project. Because ROG and NOX are considered 03 precursors, and given the region's non -attainment status of 03, the cumulative impact of the project's operational emissions would be significant. Impacts associated with project implementation have been reduced to the extent feasible. There are no feasible mitigation measures that would reduce ROG and NOX; thus, the impacts would constitute a significant and unavoidable impact. NOISE Construction Noise. The project's construction -related noise levels at the above mentioned sensitive receptors would have the potential to exceed the City's exterior daytime noise standards. Findings Changes or alterations have been required in, or incorporated into, the project that avoid or substantially lessen the significant environmental effect as identified in the Final EIR. 2. Pursuant to CEQA Guidelines Section 15091 (a)(3), specific economic, legal, social, technological, or other considerations, including provision of employment opportunities for highly trained workers, make infeasible the mitigation measures or project alternatives identified in the EIR. Facts in Support of Findings The project's construction -related noise levels at the above mentioned sensitive receptors would have the potential to exceed the City's exterior daytime noise standards. However, it should be noted that the project would be consistent with section 11.44.080 of the SCMC (special noise sources—construction and building), which states no person shall engage in any construction work which requires a building permit from the city on sites within 300 feet of a residentially zoned property except between the hours of 7:00 a.m. and 7:00 p.m., Monday through Friday, and from 8:00 a.m. to 6:00 p.m. on Saturday. Impacts associated with construction noise have been reduced to the extent feasible. However, after implementation of regulatory compliance measures and mitigation measures contained in the EIR, temporary construction noise levels would exceed exterior daytime noise standards and the impacts would constitute a significant and unavoidable impact. September 2017 62 Statement of Facts and Findings and Statement of Overriding Considerations forthe Sand Canyon Plaza Mixed -Use Project Final Environmental Impact Report Regulatory Compliance and Mitigation Measures: MM N-1 The Project shall adhere to Section 11.44.080 of the SCMC (Special Noise Sources—Construction and Building). As stated therein, no person shall engage in any construction work which requires a building permit from the City on sites within 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. MM N-2 Noise and ground -borne vibration construction activities whose specific location on the Project 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 off-site land uses. MM N-3 When possible, construction activities shall be scheduled so as to avoid operating several pieces of equipment simultaneously, which causes high noise levels. MM N-4 Flexible sound control curtains shall be placed around all drilling apparatuses, drill rigs, and jackhammers when in use. MM N-5 The Project contractor shall use power construction equipment with state-of-the-art noise shielding and muffling devices. MM N-6 Barriers such as flexible sound control curtains shall be erected around heavy equipment to minimize the amount of noise on the surrounding land uses to the maximum extent feasible during construction. MM N-7 All construction truck traffic shall be restricted to truck routes approved by the City, which shall avoid residential areas and other sensitive receptors to the extent feasible. MM N-8 A construction notice shall be prepared and shall include the following information: job site address, permit number, name and phone number of the contractor and owner or owner's agent, hours of construction allowed by code or any discretionary approval for the site, and City telephone numbers where violations can be reported. The notice shall be posted and maintained at the construction site prior to the start of construction and displayed in a location that is readily visible to the public and approved by the City. Construction Vibration Levels (Human Annoyance). Construction activities that would occur within the project site would have the potential to generate low levels of ground -borne vibration to off-site receptors. September 2017 63 Statement of Facts and Findings and Statement of Overriding Considerations forthe Sand Canyon Plaza Mixed -Use Project Final Environmental Impact Report Findings 1. Changes or alterations have been required in, or incorporated into, the project that avoid or substantially lessen the significant environmental effect as identified in the Final EIR. 2 Pursuant to CEQA Guidelines Section 15091 (a)(3), specific economic, legal, social, technological, or other considerations, including provision of employment opportunities for highly trained workers, make infeasible the mitigation measures or project alternatives identified in the EIR. Facts in Support of Findings Vibration velocities could reach as high as approximately 0.089 inches per second PPV at 25 feet from the source activity, depending on the type of construction equipment in use. This corresponds to a RMS velocity level (in VdB) of 87 VdB at 25 feet from the source activity. With respect to human annoyance, residential sensitive receptors located within 75 feet of the project site boundaries (Sensitive Receptor No. 1 located as close as 20 feet from project site) could experience construction related vibration levels of up to approximately 73-87 VbB. These levels would exceed the FTA's vibration impact threshold of 72 VdB for residences and buildings where people normally sleep. However, similar to construction noise sources, it should be noted that the project would be consistent with Section 11.44.080 of the SCMC (Special Noise Sources—Construction and Building), which states that no person shall engage in any construction work that requires a building permit from the City on sites within 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, impacts associated with construction vibration levels have been reduced to the extent feasible through imposition of mitigation measures. Nevertheless, as temporary construction vibration levels would exceed residential annoyance thresholds, impacts would be significant and unavoidable. Regulatory Compliance and Mitigation Measures: Refer to Mitigation Measures MM N-1 through MM N-8 for construction vibration. Traffic Noise on Exterior Space for Residential and Assisted Living Facility. Exterior noise levels from traffic noise for the Project's residential uses, the assisted living facility, rear yard areas, open space areas, and recreational areas would be inconsistent with the City's exterior noise standard of 65 dBA CNEL. Findings Changes or alterations have been required in, or incorporated into, the project that avoid or substantially lessen the significant environmental effect as identified in the Final EIR. 2. Pursuant to CEQA Guidelines Section 15091 (a)(3), specific economic, legal, social, technological, or other considerations, including provision of employment opportunities for highly trained workers, make infeasible the mitigation measures or project alternatives identified in the EIR. September 2017 64 Statement of Facts and Findings and Statement of Overriding Considerations forthe Sand Canyon Plata Mixed -Use Project Final Environmental Impact Report September 2017 65 Statement of Facts and Findings and Statement of Overriding Considerations forthe Sand Canyon Plaza Mixed -Use Project Final Environmental Impact Report Facts in Support of Findings Future cumulative exterior noise levels could reach up to 71.5 dBA CNEL and 73.6 dBA CNEL for the Project frontages along the segments of Sand Canyon Road and Soledad Canyon Road, respectively. In addition to these arterial roadway noise levels, the SR -14 Freeway to the south of the Project site could cause future cumulative on-site noise levels to reach up to 74.7 dBA CNEL along the southern boundary of the Project site fronting Soledad Canyon Road. While the Project would contribute to these future cumulative traffic noise levels (less than 0.8 dBA CNEL increase at worst-case location), these noise levels are primarily a result of traffic from existing conditions, ambient growth, cumulative development, and general plan buildout to the future year 2030. Based on a review of the Project plans, exterior spaces fronting Sand Canyon and Soledad Canyon Roads with a direct line -of -sight to these roadways may experience exterior noise levels above the City's exterior noise standard of 65 dBA CNEL. Specifically, such uses fronting Sand Canyon Road include multi -family attached units in Planning Areas 2 and 3, and open space and recreational areas in Planning Areas 2 and 3. And, such uses fronting Soledad Canyon Road include the assisted living facility in Planning Area 1, and open space areas in Planning Area 1, However, it should be noted that these calculations are based on the worst- case locations immediately adjacent to the property lines along the roadways. Uses with greater setbacks and without a direct line -of -sight to these roadways are expected to experience exterior noise levels below the City's exterior noise standard of 65 dBA CNEL (i.e., locations where Project building facades along the site's boundary will shield internal on-site uses from the roadway noise). Based on data published by the Federal Highway Administration, such conditions can reduce line -of -sight noise levels by approximately 10 dBA for some locations. Assuming a 10 dBA reduction described above, uses with greater setbacks and without a direct line -of -sight to the roadways would experience exterior noise levels of approximately 61.5 dBA CNEL to 64.7 dBA CNEL. These noise levels would be within the City's exterior noise standard of 65 dBA CNEL. Nevertheless, because exterior spaces fronting Sand Canyon and Soledad Canyon Roads with a direct line -of -sight to these roadways may experience exterior noise levels above the City's exterior noise standard of 65 dBA CNEL, this impact would be potentially significant. Regulatory compliance and Project -specific mitigation (i.e., Mitigation Measures MM N-9, MM N-10, MM N-12, and MM N-13) would reduce this impact to the maximum extent feasible. However, as exterior noise levels of 65 dBA CNEL cannot be guaranteed for all areas of the Project site, this impact would be significant and unavoidable. Regulatory Compliance and Mitigation Measures: MM N-9 Consistent with Policy N 3.1.2 of the City's Noise Element, where the Projected exterior noise levels could exceed 65 CNEL at single-family residences (rear yards), open space areas, and common recreational and open space areas for multi -family developments, the Applicant shall provide noise barriers, setbacks, and site design standards to reduce future on-site traffic noise levels to the maximum extent feasible. MM N-10 Consistent with Policy N 3.1.9 (Mixed -Use Developments) of the City's Noise Element, the Project shall implement a buyer and renter notification program for September 2017 66 Statement of Facts and Findings and Statement of Overriding Considerations forthe Sand Canyon Plaza Mixed -Use Project Final Environmental Impact Report residences where appropriate, to educate and inform potential buyers and renters of the sources of noise in the area and/or new sources of noise that may occur in the future. As determined by the reviewing authority, notification may be appropriate in the following areas: within 200 feet of commercial uses in mixed-use developments, potential buyers and renters should receive notice that the commercial uses within the mixed-use developments may generate noise in excess of levels typically found in residential areas, that the commercial uses may change over time, and the associated noise levels and frequency of noise events may change along with the use. MM N-12 Prior to the issuance of building permits for uses fronting Sand Canyon and Soledad Canyon Roads, the Project developer shall submit evidence demonstrating that all feasible design features have been considered to meet the City's exterior noise standard of 65 dBA CNEL. Locations that could be exposed to future exterior noise levels above 65 dBA CNEL shall consider at least the following: 1) Increase setbacks along Sand Canyon and Soledad Canyon Roads to the maximum extent feasible; 2) Consider the use of noise barriers between the roadway sources and the receptors (earthen berms, masonry walls, and vegetation may be appropriate); and/or 3) Prohibit balconies for multi -family units facing Sand Canyon and Soledad Canyon Roads. MM N-13 The Project shall implement a buyer and renter notification program for residences where appropriate, to educate and inform potential buyers and renters that due to traffic levels on Sand Canyon Road, Soledad Canyon Road and the SR -14 Freeway, noise in excess of levels typically found in residential areas may be possible. Cumulative Traffic Noise. Cumulative mobile source noise impacts would occur primarily as a result of increased traffic on local roadways due to the project, ambient growth, and related projects/cumulative development within the study area. Findings Changes or alterations have been required in, or incorporated into, the project that avoid or substantially lessen the significant environmental effect as identified in the Final EIR. 2. Pursuant to CEQA Guidelines Section 15091 (a)(3), specific economic, legal, social, technological, or other considerations, including provision of employment opportunities for highly trained workers, make infeasible the mitigation measures or project alternatives identified in the EIR. Facts in Support of Findings Cumulative mobile source noise impacts would occur primarily as a result of increased traffic on local roadways due to the project, ambient growth, and related projects/cumulative development within the study area. Cumulative traffic noise levels for the year 2030 would increase by a maximum of 4.3 dBA CNEL for the roadway segment of Sand Canyon Road, between Sand Canyon "C" Project Driveway & S. Silver Saddle Circle. Additional increases September 2017 67 Statement of Facts and Findings and Statement of Overriding Considerations forthe Sand Canyon Plaza Mixed -Use Project Final Environmental Impact Report along Sand Canyon Road would range from 1.8 dBA CNEL to 4.0 dBA CNEL. All increases along Soledad Canyon Road would be less than 1.7 dBA CNEL. Although the project would only contribute a maximum increase of 0.8 dBA CNEL for future 2030 traffic noise levels, cumulative impacts would be considered significant for the following roadway segments along Sand Canyon because cumulative increases exceed 3 dBA between: N, Silver Saddle Circle & Sand Canyon "C" Project Driveway Sand Canyon "C" Project Driveway & S. Silver Saddle Circle S. Silver Saddle Circle & Sand Canyon "A" Project Driveway Sand Canyon "A" Project Driveway & Soledad Canyon Road Cumulative mobile source noise impacts would occur primarily as a result of increased traffic on local roadways due to the project, ambient growth, and related projects/cumulative development within the study area. Although the project would only contribute a maximum increase of 0.8 dBA CNEL for future 2030 traffic noise levels, cumulative traffic noise level increases would be considered significant for the following roadway segments along Sand Canyon: between N. Silver Saddle Circle and Sand Canyon "C" Project Driveway, between Sand Canyon "C" Project Driveway and South Silver Saddle Circle, between South Silver Saddle Circle and Sand Canyon "A" Project Driveway, and between Sand Canyon "A" Project Driveway and Soledad Canyon Road. As no feasible mitigation is available to reduce this impact, cumulative traffic noise impacts would be significant and unavoidable. 5.5 ALTERNATIVES TO THE PROPOSED PROJECT As set forth in these findings, the implementation of the proposed project will result in significant impacts that are considered unavoidable. CEQA requires that an EIR include an analysis of a reasonable range of feasible alternatives to a proposed project capable of avoiding or substantially lessening any significant adverse environmental impact associated with the project. The Final EIR addresses the environmental effects of alternatives to the proposed project. A description of these alternatives, a comparison of their environmental impacts to the proposed project, and the City's findings are listed below. These alternatives are compared against the project relative to the identified project impacts, summarized in the sections above, to the project objectives, as stated in Chapter 3.0, Project Description, of the Final EIR. In making the following alternatives findings, the City independently reviewed and considered the information EIR, including the information provided in the comments thereto. Alternatives Analyzed of Santa Clarita certifies that it has on alternatives provided in the Final on the Final EIR and the responses Four alternatives to the Project were analyzed in the Final EIR: ■ Alternative 1: No Project Alternative ■ Alternative 2: Increased Commercial and Office ■ Alternative 3: Ridgeline Preservation September 2017 68 Statement of Facts and Findings and Statement of Overriding Considerations forthe Sand Canyon Plaza Mixed -Use Project Final Environmental Impact Report ■ Alternative 4: ACOE-CDFW Avoidance September 2017 69 Statement of Facts and Findings and Statement of Overriding Considerations forthe Sand Canyon Plaza Mixed -Use Project Final Environmental Impact Report Off -Site Alternatives. Alternative sites of generally the same size in the eastern of the City of Santa Clarita do not exist. Consistent with General Plan intent, the Project involves development of an infill parcel. No potential alternative project sites in the local vicinity are similar in acreage or provide similar characteristics. No potential alternative sites could serve primary project objectives. For the reasons cited above, no alternative sites were analyzed for this Project. Table 2 provides a comparison of environmental impacts for each of the alternatives in relation to environmental impacts associated with the Project.

Under this Alternative, no development or redevelopment would occur beyond what exists today, and the project area would retain the existing general plan and zoning designations of Mixed Use Neighborhood (MXN) and Urban Residential 3 (UR -3). In addition, the existing circulation system would remain the same. Findings Alternative 1 would eliminate the significant and unavoidable air quality and noise impacts. 2. Alternative 1 would reduce and eliminate potentially significant impacts for, aesthetics, air quality, biological resources, cultural resources, geology and soils, hazards, noise, public services, traffic and circulation, and utilities. 3. The findings of the proposed project set forth in this document and the overriding social, economic, and other issues set forth in the Statement of Overriding Considerations provide support for the proposed project and the elimination of this alternative from further consideration. Facts in Support of Findings: With the No Project Alternative, the Sand Canyon Plaza Mixed -Use Project would not be implemented and the existing mobile home units would remain. Because no grading, construction, or operational activities would occur under this alternative, there would not be associated impacts related to aesthetics, air quality, biological resources, cultural resources, geology and soils, greenhouse gas, hazards, hydrology and water quality, land use and planning, noise, population and housing, public services, traffic and circulation, and utilities. Adoption of Alternative 1 would not necessarily preclude ultimate development of the Project site in accordance with the existing General Plan and zoning regulations for the site, or land use designations or regulations subsequently adopted by the City. However, if development is proposed in the future, like the Project, such development would be subject to environmental review. In comparison to the proposed project, the No Project Alternative results in greater impacts for aesthetics; hazards and hazardous materials; land use; and population and housing. The No Project Alternative results in similar impacts for agriculture and forestry resources; cultural resources; and mineral and energy resources. The No Project Alternative results in fewer impacts to air quality; biological resources; geology and soils; greenhouse gas emissions; hydrology and water quality; noise; public services; trans portationitraffic; solid waste; wastewater; and water supply. All significant unavoidable impacts related to air quality and noise impacts would be eliminated with this Alternative. The No Project Alternative would not implement any of the overarching objectives of the proposed project to create a new mixed-use community with connected neighborhoods that provides for residential, commercial, and recreational uses in close proximity to each other; provide a rich set of public spaces; implement sustainable development principles, including greater energy efficiency, waste reduction, drought -tolerant landscaping, use of water efficiency measures, and use of recycled materials and renewable energy sources; provide a September 2017 71 Statement of Facts and Findings and Statement of Overriding Considerations forthe Sand Canyon Plaza Mixed -Use Project Final Environmental Impact Report tax base to support public services and infrastructure; create permanent jobs on-site through the incorporation of commercial land uses to assist the City in meeting its jobs/housing balance, and restore and minimize impacts to important biotic resources, including heritage oak trees. Therefore, none of the project objectives would be met under the No Project Alternative.

Alternative 2 would also remove 60 dwelling units from Planning Area 2. None of the assisted living units would be constructed in Planning Area 1. All other uses on the project site would remain as proposed. Findings 1 Alternative 2 would not reduce or eliminate the significant and unavoidable air quality and noise impacts. 2. Alternative 2 would not reduce or eliminate potentially significant impacts for, aesthetics, air quality, biological resources, cultural resources, geology and soils, hazards, noise, public services, traffic and circulation, and utilities. 3. The findings of the proposed project set forth in this document and the overriding social, economic, and other issues set forth in the Statement of Overriding Considerations provide support for the proposed project and the elimination of this alternative from further consideration. Facts in Support of Findings: In comparison to the proposed project, Alternative 2 would result in similar impacts relative to aesthetics; agriculture and forestry resources; air quality; biological resources; cultural resources; greenhouse gas emissions; hazards and hazardous materials; hydrology and water quality; mineral and energy resources; noise; population and housing; parks and recreation; public services; transportation/traffic; solid waste; wastewater, and water supply: Air Quality, Under Alternative 2, commercial building area would increase by 29,400 square feet and office building area would increase by 30,000 office square feet. These uses would replace the assisted living facility and 60 residential units. This Alternative would result in a change in project trip generation; however, this change would be minor and therefore would result in similar air quality impacts as compared to the Project. Noise. Under this alternative, the development footprint would remain the same as the Project. There would be no changes to project grading, installation of infrastructure and building construction, and therefore no change in construction related noise impacts. As indicated previously, there will be no significant change in vehicle trip generation with this alternative. Consequently, operational noise impacts would remain substantially the same as compared to the Project. As noted above, the significant unavoidable impacts related to air quality and noise would be similar to the Project, and thus, would not be reduced or eliminated under Alternative 2. September 2017 73 Statement of Facts and Findings and Statement of Overriding Considerations forthe Sand Canyon Plaza Mixed -Use Project Final Environmental Impact Report Alternative 2 fully meets 14 objectives and partially meets the remaining six objectives, as shown below, September 2017 74 Alternative 2: Project Objective Increased Commercial and Office Land Use Planning Objectives Create a new mixed-use community with connected neighborhoods that provides for residential, Partially Meets commercial and recreational uses in close proximity to each other.

To a lesser extent, the Ridgeline Preservation Alternative would remove 29 dwelling units from Planning Area 5. This alternative would also increase open space/landscape areas within the project area. None of the other site plan specifics would be changed. Findings Alternative 3 would reduce but not eliminate the significant and unavoidable air quality impacts, and would not eliminate the significant and unavoidable noise impacts. 2. Alternative 3 would reduce but not eliminate potentially significant impacts for aesthetics, air quality, biological resources, and geology and soils. 3. Alternative 3 would not reduce or eliminate potentially significant impacts for cultural resources, hazards, noise, public services, traffic and circulation, and utilities. 4. The findings of the proposed project set forth in this document and the overriding social, economic, and other issues set forth in the Statement of Overriding Considerations provide support for the proposed project and the elimination of this alternative from further consideration. Facts in Support of Findings: The development anticipated under the Alternative 3 includes the same mix of land uses anticipated for the proposed Sand Canyon Plaza Mixed -Use Project, although with less residential units. In comparison to the proposed project, Alternative 3 would result in fewer impacts relative to aesthetics; air quality; and geology and soils. Impacts for the remaining 19 topical areas would be similar under Alternative 3 as those anticipated for the proposed project. Air Quality. Under Alternative 3, 29 dwelling units would not be constructed, resulting in a reduction in Project grading and an increase in open space. This reduction in project grading would reduce construction related impacts. From an operational standpoint, this alternative would reduce vehicle trips, which in turn would reduce emissions. Alternative 3 would result in a reduction of air quality impacts as compared to the Project. Noise. Under this alternative, the development footprint would remain substantially the same as the Project. There would be minor reductions in project grading, the development footprint, installation of infrastructure, and building construction. However, these changes would not be significant. Consequently, noise impacts would remain substantially the same as compared to the Project. As noted above, the significant unavoidable impacts related to air quality would be reduced but not eliminated under Alternative 3. And the noise impacts would not be reduced or eliminated under Alternative 3. September 2017 76 Statement of Facts and Findings and Statement of Overriding Considerations forthe Sand Canyon Plaza Mixed -Use Project Final Environmental Impact Report Alternative 3 fully meets all 20 project objectives, as shown below. Project Objective Land Use Planning Objectives Create a new mixed-use community with connected neighborhoods that provides for residential, commercial and recreational uses in close proximity to each other.

Meets Alternative 3 was identified as the environmentally superior alternative to the Project. September 2017 77 Statement of Facts and Findings and Statement of Overriding Considerations forthe Sand Canyon Plaza Mixed -Use Project Final Environmental Impact Report The modifications made by the Planning Commission during their review have resulted in a revised Project that is similar to this Alternative. Additionally, those modifications have resulted in the creation of a two -acre private park, which is a benefit as compared to this Alternative. ALTERNATIVE 4 — ACOE-CDFW AVOIDANCE Alternative 4 would avoid jurisdictional areas associated with Sand Canyon Wash. Specifically, 7,800 square feet of commercial building area would be eliminated in Planning Area 1, 44 units would be eliminated in Planning Area 2, Planning Area 3, consisting of 10.1 acres, would be converted from residential use to open space (removing 122 units), Planning Area 4 would be reduced by 42 units, and Planning Area 5 would be reduced by 42 dwelling units. The above modifications would result in an increase of 22.4 acres of open space. In total, Alternative 4 would remove 250 units when compared to the project. Findings Alternative 4 would reduce but not eliminate the significant and unavoidable air quality and noise impacts. 2. Alternative 4 would reduce but not eliminate potentially significant impacts for aesthetics, air quality, biological resources, cultural resources, geology and soils, noise, public services, traffic and circulation, and utilities. 3. Alternative 4 would not reduce or eliminate potentially significant impacts for hazards. 4. The findings of the proposed project set forth in this document and the overriding social, economic, and other issues set forth in the Statement of Overriding Considerations provide support for the proposed project and the elimination of this alternative from further consideration. Facts in Support of Findings: The development anticipated under the Alternative 4 includes the same mix of land uses anticipated for the proposed Sand Canyon Plaza Mixed -Use Project, although with much less residential units and non-residential square footage. In comparison to the proposed project, the Alternative 4 would result in greater impacts for land use and planning and population and housing. Alternative 4 results in fewer impacts for aesthetics; air quality; biological resources; cultural resources; geology and soils; greenhouse gas emissions; hydrology and water quality; noise; public services; transportation/traffic; solid waste; wastewater, and water supply. Alternative 4 results in similar impacts for agriculture and forestry resources and hazards and hazardous materials. Air Quality. Under Alternative 4, 250 residential units and 7,800 square feet of commercial space would not be constructed, resulting in a reduction in Project grading and increase in open space. This reduction in Project grading would reduce construction related impacts. From an operational standpoint, this alternative would reduce vehicle trips, which in turn would reduce emissions. Alternative 4 would result in a reduction of air quality impacts as compared to the Project. September 2017 78 Statement of Facts and Findings and Statement of Overriding Considerations for the Sand Canyon Plaza Mixed -Use Project Final Environmental Impact Report Noise. Under Alternative 4, the development footprint would be reduced as compared to the proposed Project. There would be reductions in project grading, the installation of infrastructure, and building construction. From an operational standpoint, there would be fewer residential units and less commercial square footage, resulting in reduced on-site noise generation. Consequently, noise impacts would be reduced as compared to the Project. As noted above, the significant unavoidable impacts related to air quality and noise would be reduced but not eliminated under Alternative 4.

The City of Santa Clarita City Council hereby recommends certification of Final Environmental Impact Report based on the following findings and conclusions. 6.1 FINDINGS The project would have the potential for creating significant adverse impacts. These significant adverse environmental impacts have been identified in the EIR and will require mitigation as set forth in the Findings. Significant adverse impacts which cannot be mitigated to a level of insignificance after mitigation include air quality and noise. 6.2 CONCLUSIONS 1. Except as to those impacts stated above relating to air quality and noise, all other significant environmental impacts from the implementation of the proposed project have been identified in the EIR and, with implementation of the mitigation measures identified, will be mitigated to a less than significant level. 2. Alternatives to the proposed project, which could potentially achieve the basic objectives of the proposed project, have been considered and rejected in favor of the proposed revised project. 3 Environmental, economic, social, and other considerations and benefits derived from the development of the proposed project, as further discussed in Section 7.0, override and make infeasible any alternatives to the proposed project or further mitigation measures beyond those incorporated into the proposed project. September 2017 81 Statement of Facts and Findings and Statement of Overriding Considerations forthe Sand Canyon Plaza Mixed -Use Project Final Environmental Impact Report 7.0 STATEMENT OF OVERRIDING CONSIDERATIONS 7.1 INTRODUCTION The City of Santa Clarita (City) is the Lead Agency under CEQA for preparation, review, and certification of the Final EIR for the Sand Canyon Plaza Mixed -Use Project (project). As the Lead Agency, the City is also responsible for determining the potential environmental impacts of the proposed action and which of those impacts are significant, and which can be mitigated through imposition of mitigation measures to avoid or minimize those impacts to a level of less than significant. CEQA then requires the Lead Agency to balance the benefits of a proposed action against its significant unavoidable adverse environmental impacts in determining whether or not to approve the proposed project. In making this determination the City is guided by CEQA Guidelines Section 15093, which provides as follows: a) CEQA requires the decision-making agency to balance, as applicable, the economic, legal, social, technological, or other benefits of a proposed project against its unavoidable environmental risks when determining whether to approve the project. If the specific economic, legal, social, technological, or other benefits of a proposal (sic) project outweigh the unavoidable adverse environmental effects, the adverse environmental effects may be considered "acceptable." b) When the lead agency approves a project which will result in the occurrence of significant effects which are identified in the final EIR but are not avoided or substantially lessened, the agency shall state in writing the specific reasons to support its action based on the final EIR and/or other information in the record. The statement of overriding considerations shall be supported by substantial evidence in the record. c) If an agency makes a statement of overriding considerations, the statement should be included in the record of the project approval and should be mentioned in the notice of determination. This statement does not substitute for, and shall be in addition to, findings required pursuant to Section 15091. In addition, Public Resources Code Section 21081(b) requires that where a public agency finds that specific economic, legal, social, technological, or other considerations, including considerations for the provision of employment opportunities for highly trained workers, make infeasible the mitigation measures or alternatives identified in an EIR and thereby leave significant unavoidable effects, the public agency must also find that overriding economic, legal, social, technological, or other benefits of the project outweigh the significant effects of the project. Pursuant to Public Resources Code Section 21081(b) and the CEQA Guidelines Section 15093, the City has balanced the benefits of the project against the following unavoidable adverse impacts associated with the project and has adopted all feasible mitigation measures with respect to these impacts. The City also has examined alternatives to the project, none of September 2017 82 Statement of Facts and Findings and Statement of Overriding Considerations forthe Sand Canyon Plaza Mixed -Use Project Final Environmental Impact Report which both meet the project objectives and is environmentally preferable to the project for the reasons discussed in the Statement of Facts and Findings (above). The City of Santa Clarita City Council, having reviewed and considered the information contained in the Sand Canyon Plaza Mixed Use Project, the Final EIR, Responses to Comments, and the public record in its entirety, hereby adopts the following Statement of Overriding Considerations that have been balanced against the unavoidable adverse impacts in reaching a decision on this project. 7.2 SIGNIFICANT UNAVOIDABLE IMPACTS Although all potential project impacts have been substantially avoided or mitigated as described in the preceding findings, there is no complete mitigation for the following project impacts: • Air Quality: Regional Operational Emissions • Air Quality: Cumulative Operational Emissions • Noise: Construction Noise • Noise: Construction Vibration Levels (Human Annoyance) • Noise: Traffic Noise on Exterior Space for Residential and Assisted Living Facility • Noise: Cumulative Traffic Noise Details of these significant unavoidable adverse impacts were discussed in the Final EIR and are summarized or were otherwise provided in the Statement of Facts and Findings (above). 7.3 OVERRIDING CONSIDERATIONS To the extent that the significant effects of the project are not avoided or substantially lessened to below a level of significance, the City of Santa Clarita City Council, having reviewed and considered the information contained in the Final EIR and the public record, and having balanced the benefits of the project against the unavoidable effects which remain, finds such unmitigated effects to be acceptable in view of the following overriding economic, social and other considerations, each of which the City Council finds is individually sufficient to justify issuance of a Statement of Overriding Considerations: The City Council hereby finds that each of the specific economic, legal, social, technological, environmental, and other considerations, and the benefits of the project separately and independently outweigh these remaining significant, adverse impacts and is an overriding consideration independently warranting approval of the project. The remaining significant adverse impacts identified in Section 7.2, above are acceptable in light of each of these overriding considerations, and the substantial evidence that supports the enumerated benefits of the project can be found in the Statement of Facts and Findings herein, the Final EIR, the project itself, and the record of all proceedings in connection with the approval of the project. In the event that any court decision or regulatory action results in a determination that there are additional remaining significant impacts resulting from the City's approval of the project that cannot be avoided even with the incorporation of all feasible mitigation measures into the project, September 2017 83 Statement of Facts and Findings and Statement of Overriding Considerations forthe Sand Canyon Plaza Mixed -Use Project Final Environmental Impact Report the Statement of Facts and Findings and Statement of Overriding Considerations herein shall be deemed to apply to such additional remaining significant impacts. 2. The project establishes various objectives that will improve the project site and provide a benefit to the community, namely: • Create a new mixed-use community with connected neighborhoods that provides for residential, commercial and recreational uses in close proximity to each other. • Provide a sensitive and compatible Project through the use of appropriate grading, landscape, and water quality methods. • Provide development and transitional land use patterns that do not conflict with surrounding communities and land uses. • Arrange land uses to reduce vehicle miles traveled and energy consumption, and to encourage pedestrian mobility. • Design neighborhoods to create a unique identity and sense of place. Design neighborhoods to locate a variety of residential and non-residential land uses in close proximity to each other and major road corridors, transit, and trails. • Provide a rich set of public spaces. • Implement sustainable development principles, including greater energy efficiency, waste reduction, drought -tolerant landscaping, use of water efficiency measures, and use of recycled materials and renewable energy sources. • Create and enhance opportunities for non -vehicular travel and encourage pedestrian mobility by providing an internal pedestrian circulation system that links residential neighborhoods to on-site recreation areas, regional trail systems, and neighborhood retail/commercial areas. • Foster the design and integration of a mutually beneficial relationship between the natural and built environments, and implement sensitive land use transition treatments, attractive streetscapes, and high quality design themes. • Integrate a new community into the City's existing and planned circulation network. • Provide a landscape design emphasizing a pleasant neighborhood character and inviting streetscapes. • Provide on-site recreational facilities to meet the demands of future residents. • Enhance and augment the housing market by providing a variety of housing types and densities to meet the varying needs of future residents. • Adopt development regulations that provide flexibility to respond and adjust to changing economic and market conditions. • Provide a tax base to support public services and infrastructure. • Create permanent jobs on-site through the incorporation of commercial land uses to assist the City in meeting its jobs/housing balance. • Adopt development regulations and guidelines that allow site, parking and facility sharing, and other innovations that reduce the costs of providing public services. • Restore and minimize impacts to important biotic resources. September 2017 84 Statement of Facts and Findings and Statement of Overriding Considerations forthe Sand Canyon Plaza Mixed -Use Project Final Environmental Impact Report • Minimize impacts to oak trees and incorporate, where possible, oak trees into public spaces. 3. The project establishes the general type, parameters, and character of the development in order to develop an integrated mixed-use development that is compatible with the surrounding area. 4. The project incorporates objectives and visioning efforts for the area from the One Valley One Vision Plan. Furthermore, the project is intended to implement the City of Santa Clarita's General Plan, 5. The project will positively contribute to the economic vitality and revitalization in the City by developing a project that supports a market driven economy, creates a mixed-use environment, and redevelops an underutilized site with the highest and best use. 6. The project will enhance the aesthetic environment by replacing existing mobile home units with new buildings and providing increased and improved landscaping and open space areas. 7. The project provides a spectrum of housing which will help to meet the long-term housing needs of the City of Santa Clarita Valley, and will satisfy a wide array of economic and social needs, and lifestyles. Project housing includes: multi -family rental apartments; multi -family attached townhomes; and multi -family detached or attached condominiums. 8. The project will provide a range of quality housing opportunities, including 580 residential units, as well as on-site recreation and landscaped areas, that contribute to the projected housing needs in the City of Santa Clarita and the Santa Clarita Valley. 9. The project will provide 60,000 square feet of retail commercial uses and an 85,000 - square -foot assisted living facility to contribute to the commercial space needs in the City of Santa Clarita and for future residents of the project. 10. The project will result in the creation of up to 149 permanent jobs within its commercial areas on a site where no jobs currently exist. 11. The project will create a highly livable, sustainable, pedestrian -friendly environment that encourages alternative means of transportation. 12. The project provides for non -vehicular modes of transportation in a system of trails, sidewalks and pedestrian pathways. The project's Mobility Plan creates and enhances opportunities for non -vehicular travel through encouraging pedestrian mobility from the project's residential areas to the commercial uses, and to existing and future off-site bicycle facilities and trails. 13. The project would complete various improvements to Soledad Canyon Road to include widening for roadway purposes. The project would also widen Sand Canyon Road for roadway and trail purposes and construct two single lane roundabouts; one at "B" Drive and Sand Canyon Road and the other at "C" Drive and Sand Canyon Road. Most of September 2017 85 Statement of Facts and Findings and Statement of Overriding Considerations forthe Sand Canyon Plaza Mixed -Use Project Final Environmental Impact Report Sand Canyon Road would remain at two lanes (one in each direction), with grading of the full right-of-way to potentially accommodate widening if needed in the future. 14. The project will provide off-site roadway and intersection improvements to the arterial highway system and to the SR -14 SB Ramps at Soledad Canyon, which will benefit residents and businesses within the area. 15. The project will preserve or replace biotic resources and heritage oaks. 16. The project will encourage the use of drought -tolerant, fire -retardant, and native plants in landscaping, and thereby promote water conservation. 17, The applicant has voluntarily entered into a school mitigation agreements with the Sulphur Springs Union School District and will be entering into an agreement with the William S. Hart Union High School District. These agreements call for payments that are in excess of the current development fees required by State law. 18- The project's residents and businesses would generate revenue in the form of sales taxes, property taxes, fees, etc. that would be available to the City to fund public services. Therefore, the City of Santa Clarita City Council, having reviewed .and considered all of the information contained in the Final EIR and the public record, adopts the Statement of Overriding Considerations that has been balanced against the unavoidable adverse impacts in reaching a decision on this project.
