BACKGROUND The City of Santa Clarita (City) has been working with the County of Los Angeles (County) for proposed improvements to two existing bridges along Sierra Highway over the Santa Clara River. Page 1 Packet Pg. 78 O Pursuant to the County's Bridge Inspection Report (BIR), both bridges were identified for needed improvements. The proposed improvements consist of removing and replacing the southbound bridge, widening the northbound bridge, and constructing a 13-foot-wide median between them. The exterior side of both bridges would add six -foot -wide sidewalks with eight -inch curbs, concrete barriers, street lights, and railings. These improvements will increase overall pedestrian safety and fulfill the conditions for both bridges as referenced in the County's BIR. The County Department of Public Works had originally designed the project and completed the design plans on May 12, 2015. The City hired MNS Engineers Inc. to perform a constructability review on the construction documents and comments were provided on April 30, 2019, identifying items that needed to be addressed prior to bidding and constructing the project. A Request for Proposal (RFP) for the design contract was prepared and posted on BidNet on September 28, 2020. The RFP solicited firms to identify their relevant experience with similar projects and demonstrate their design approach for this project. The proposal tasks include addressing the constructability review comments, updating the plans and specifications, furnishing a complete bid package, and becoming the new Engineer of Record for this project. On November 3, 2020, the City received one proposal. Staff reviewed the proposal and, based on their evaluation, scored the submitted proposal on a 100-point scale. Rank Company Score Location 1. Dokken Engineering 94.0 San Diego, CA The scoring system heavily emphasized the understanding of the following: scope and approach to the required work; key development items; potential issues and resolutions; the consultant's previous experience with similar projects and experience working with the City; qualifications of the project team and their resources; and organization of the proposal. Additionally, the firm was asked to provide detailed hours and a scope of work required to complete the construction documents. Based on their design experience, including previous City bridge projects, and the completeness of their proposal, staff recommends the City Council award the design contract to Dokken Engineering. Dokken Engineering demonstrated an in-depth understanding of the project's needs and provided a detailed scope of work. They also illustrated their understanding of the design needs for the project by identifying key design issues, providing valuable engineering ideas and a reasonable schedule of work, and identifying a comprehensive design team for the project. The requested contingency will cover any unforeseen modifications during coordination with utility companies and additional work required by the City. California Government Code 4526 prescribes the selection of architectural and engineering Page 2 Packet Pg. 79 O services be based on demonstrated competence and professional qualifications necessary for the satisfactory performance of the services required and does not authorize the selection of a professional architect and engineering services based on cost.

We understand the challenges this project will present to design, coordinate, and construct. Our team of lead bridge, roadway, and environmental engineers along with utility coordination specialists have visited the project site and developed an understanding of the key project issues presented herein. Project Approach The City of Santa Clarita has been working with the County of Los Angeles on preliminary plans for improvements to the northbound and southbound bridges along Sierra Highway over the Santa Clara River. Based on our understanding of the Project we have developed an approach which minimizes utility relocations, addresses potential structural insufficiencies with the existing bridge, provides pedestrian access which complies with the Americans with Disabilities Act (ADA), and accounts for river hydraulics as well as storm water quality management. We have prepared exhibits, included at the end of this Introduction Section, illustrating a preliminary design using the bridge layout as currently designed in this RFP and an alternative bridge layout which maintains the existing western limits of the southbound bridge by reducing the 13' median. Our alternative layout was developed to protect the existing power poles in place with temporary electric line relocations and temporary power outages during pile driving. However, should the temporary power outages during construction not be allowed by SCE we would propose use of pile splicing techniques that reduce the height of piles during construction. Dokken's in-house capabilities include civil, traffic, structural, environmental, and drainage which improves uniformity of the overall design. Based on our understanding of the Project we have developed the following table to identify key project issues, provide our team's recent experience on such issue, and describe the unique benefit Dokken brings to the City.

Utility Relocations Within the project envelope, there are multiple existing utilities including overhead electrical and telephone lines, gas mains, water mains, sewer, and various telecommunication lines located around, on, and within the existing bridge structure. Facilities are owned and operated by various agencies including Southern California Edison (SCE), Southern California Gas Company (So Cal Gas), Santa Clarita Valley Water Agency (SCVWA), Castaic Lake Water Agency (CLWA), Los Angeles County Public Works (DPW), AT&T, Clear Channel, Level 3, Spectrum, and Verizon. 0 @ ��.� Page 1 3 L' N G IN E N It NC! SIERRA HIGHWAY BRIDGE NEW ENGINEER OF RECORD TO ADDRESS CONSTRUCTABILITY REVIEW PROPOSAL # EN G-20-21-S3038 The draft set of plans provided with the RFP identifies the existing large, tubular steel poles as well as smaller, wood poles located west of the southbound bridge to be relocated by others (denoted "RU" on the plans). One of the key project issues is bridge construction around these existing SCE transmission and distribution overhead lines on the west side of the bridge. The existing electric poles and overhead lines run parallel to the westside of the Sierra Highway bridge, before splitting east and crossing Sierra Highway just north of the northerly bridge abutment. The original bridge plan replaces the west side of the bridge with a widened bridge structure that requires pile driving activities directly under the existing overhead electrical lines. The proposed sidewalk to tie-in existing Sierra Highway to the widened bridge section would also conflict with the existing steel tubular poles south of the bridge. These direct conflicts require the relocation of the steel transmission poles and electrical overhead lines. From our extensive experience working with SCE and other electrical companies, this type of major relocation typically requires a minimum of one year for development and coordination of relocation plan design and approximately 12-15 months for fabrication of the engineered tubular steel pole. Also note that these estimated durations do not include easement acquisition timelines, or other potential right-of-way coordination that SCE may require, since the pole relocations would likely be outside of available public right-of-way. With these estimated timeframes, SCE would begin work to generate relocation plans and perform pole load calculations at minimum two years from notification of conflict, subsequently delaying the project construction. We note that the preliminary bridge design for the new, widened westerly structure places the new west edge of bridge approximately six feet further under these existing overhead utility lines, which if not relocated, could create constructability issues during installation of foundation piles if proper clearance requirements cannot be met. Our design team's solution would be to reduce the new median from 13.5' to 6', essentially widening the bridge in the middle, and holding the west edge of bridge. By maintaining the west edge of bridge, we can protect the existing steel tubular poles to the south of the bridge, which allows for a new sidewalk towards the east (see "Pile installation at Piers" Figure on the next page). Based on available data and research, the voltages of the electrical line are 66kV and 16kV, with the 66kV lines towards the top of the pole line and the 16kV lines located lower on the poles. One approach we would propose to SCE temporarily relocates the 16kV distribution lines towards the east, on temporary wood poles within right-of-way, and de - energizes the 66kV transmission lines during pile driving activities for the new bridge structure. Temporary relocation of the distribution lines would typically require 6-9 months for design and coordination and approximately 1-2 months for relocation. Once the bridge structure has been constructed, the mom, distribution lines would be reinstalled on the existing transmission poles. A similar temporary relocation was completed for San Diego Gas & Electric (SDG&E) distribution electrical lines for the Mid -Coast Corridor Transit Project in San Diego. Our team worked in close coordination with both the utility company and construction °r contractor to successfully design and execute this temporary relocation work for the proposed trolley bridge construction. Our alternative layout removes the left turn lane that allows for U-turns iG/r n to the south of the bridges. This U-turn movement allows i southbound traffic to avoid the traffic signal at Jake's Way by entering the local residential community at Sand Drive and this ge, TSP h fie SW Qua g Y Y drdht,,, . proposed elimination may require additional traffic analysis, which l�� can be completed in-house staff via an optional task for an expedited traffic analysis if needed. Power line relocations (whether permanent or temporary) are not warranted for the construction of abutment pile foundations, as the foundations are far enough away to clear temporary construction clearance requirements (15 feet for 66 KV lines) required by the California Code of Regulations (CCR) section 2946. (See Pile installation at North Abutment on the following page). 0 @ ��.� Page 1 4 L' N G IN E N It NU! SIERRA HIGHWAY BRIDGE NEW ENGINEER OF RECORD TO ADDRESS CONSTRUCTABILITY REVIEW PROPOSAL # EN G-20-21-S3038 Structural Insufficiency The existing northbound bridge is proposed to be widened by twelve -feet, three -inches (12'-3") to the east by driving additional piles, extending the existing pile caps and pier walls, and the addition a single reinforced concrete T-beams. This widening will accommodate shoulders and a six-foot (6) sidewalk and would eliminate what was, at the time of project initiation, a "functionally obsolete" flag in the inspection report due to inadequate deck width for the three northbound lanes of traffic carried by this bridge, built in 1968. In addition to being "functionally obsolete", the Bridge Inspection Report (BIR) indicates that the bridge is considered "structurally deficient" because of the poor condition of the deck slab. The existing plan set indicates a decktreatment (i.e., high molecular weight methacrylate sealer) to help seal cracks and prevent further deterioration, the BIR also indicates that approximately ten percent of the deck area is in fair to poor condition, which likely means ten percent of the deck has unsound concrete that will need to be removed and patched prior to deck treatment. This work is not reflected in the current plan set. In addition, while the BIR indicates that the bridge foundations were determined to be stable for the assessed or calculated scour condition, the depth of footings do not meet current standards for depth relative to anticipated scour. We understand that the Los Angeles County Department of Public Works performed hydraulic analyses for this project, but no document has been published for review or approval. The geotechnical report prepared by URS indicates a total scour depth of 17 feet, which would be below the bottom of footings shown for both the existing northbound bridge and the proposed southbound bridge. This does not meet requirements in Caltrans Amendments to AASHTO LRFD Bridge Design Specifications, 81' Edition, as detailed in Caltrans Memos to Designers 16-1, Hydraulic Design for Structures over Waterways. New and widened pile footings required to have the top of footing below the long term plus contraction scour depth and the bottom of footing below the total scour depth. The existing portion of the pile cap to remain may either be protected by channel improvements or by the addition of piles, if necessary.

The proposed raised median spanning between the existing northbound and proposed southbound bridges is a concern due to expected differential dead load and live load deflections. This is always a concern when connecting a new bridge deck to an existing one but is especially of concern in this case because the spans on the new bridge are twice as long as on the existing bridge. Consequently, the maximum dead load and live load deflections of the new bridge will occur at the piers of the existing bridge (which cannot deflect). Without isolation, this raised median is likely to be an ongoing maintenance problem and is likely to deteriorate prematurely. From an environmental standpoint, it is usually better to leave an open space if that median area won't be used. Providing barriers at the median would allow for an open space and eliminate the issues with connecting the two differently configured bridges. At a minimum, a construction sequence would need to be shown that specifies that the slab should be placed a minimum of 28 days after the release of the differential displacements between the two different bridge span The plans do not indicate the presence of any seismic retrofits or approach slabs on the existing bridges. While pier walls have generally performed well in earthquakes and often do not require retrofit, the existing pier walls are only one foot, three inches (1'-3") wide and are pinned at the pile caps. Dokken will need to evaluate the seismic vulnerabilities of the existing bridge piers and abutments and conform with Caltrans guidelines for seismic evaluation of bridges to be widened as described in Caltrans Memos to Designers 9-3 and 20-12. Additionally, the performance of the completed structure must conform to Memos to Designers 20-4. 1 As noted in the constructability review, the plans and specifications have inconsistent references to design criteria, standard specifications, and standard plans. The bridge design will need to be updated to the 61h edition of the AASHTO LRFD Bridge Design Specifications with Caltrans Amendments, or optionally to the 81h edition. The seismic design will need to be updated to Caltrans Seismic Design Criteria, Version 1.7 or 2.0 (optional) and Standard Plans and Specifications will need to be updated to Caltrans 2018 versions. Staged Construction There are three lanes of vehicular traffic in each direction along this portion of Sierra Highway with an existing five -foot - wide sidewalk along the eastern side only. An approach to staged construction that provides safe access for vehicles, pedestrians, and cyclists was developed by Dokken during preliminary design and included in the RFP. As shown on these draft staging plans at least two lanes of travel will need to be maintained for vehicles throughout construction, which presents a challenge with complete replacement of the easterly structure. Because of this need to maintain two lanes of traffic in each direction for vehicles, while providing safe passage for bicycles and pedestrians, it becomes evident that the widening of the easterly structure must occur first in order to utilize the newly widened structure for all traffic while the westerly structure is replaced. A brief description of the approach to staging follows as such; Stage 1) Reduce vehicular traffic to 2-lanes each direction and shift bikes and pedestrians onto the westerly structure while the easterly structure is widened, Stage 2) Shift all traffic onto the widened easterly structure to demolish and replace the westerly structure, Stage 3) Shift southbound traffic back onto the new easterly structure (leaving northbound traffic to the west) to complete median work. In general, we concur with the approach to staging as depicted on the draft staging plans, however we will revisit these plans in greater detail during design to ensure impacts to the travelling public are minimized throughout construction. 0��.N Page 1 6 L'DN G IN E N It NU! SIERRA HIGHWAY BRIDGE NEW ENGINEER OF RECORD TO ADDRESS CONSTRUCTABILITY REVIEW PROPOSAL # EN G-20-21-S3038 Due to the location of the overhead electrical lines crossing Sierra Highway at the northerly bridge abutment and multiple stages of construction, existing utilities around and within the bridge structures will require temporary relocation to maintain clearances during construction. This includes visible overhead utilities, an existing AT&T duct package on the east side of the easterly bridge, and an existing 6" gas main within the easterly structure. In the figure below (titled "Pile Installation — North Abutment") we have illustrated that construction of the northerly abutment piles will not impact the existing overhead utility lines that cross Sierra Highway. Dokken will work closely with the utility companies to identify viable interim and/or permanent relocations to maintain services during construction. Our team will obtain facility maps and record drawings, mapping of existing utilities, verifying mapping through potholing/surveying, and re-evaluate the utility conflicts identified on the draft plans. We will identify design and/or construction strategies that allow for protection of existing utilities in place wherever feasible. For utilities determined to be in conflict, Dokken Engineering work with the City to re-engage utility representatives and identify resolutions to conflicts, prepare a composite utility relocation plan, incorporate a utility relocation schedule in the project specifications, evaluate the need for an approach to staged construction, and provide design support during construction for all relocation efforts. 66 W TRANSMISSION LINES T.yp 15" Min CLEARANCE Affill ` PILE DRIVING LOAD PRECAST PATTERED PILE AT ABUTMEI'dT TOE TE10PORA,RY SHORING FOR ABUTMENT EXCAVATION BOT-1 OM OF FOOTING ELEVATION Environmental Understanding Exist POWER POLE.

Dokken is committed to providing complete environmental services to our clients. This goes beyond the environmental document process and includes coordination with regulatory agencies for all necessary environmental permits. Dokken has experience coordinating with the U.S. Army Corps of Engineers, California Department of Fish and Wildlife, California State Water Quality Control Board, Regional Water Quality Control Boards, Flood Control Districts, and many other agencies. Dokken regularly facilitates coordination with the permitting agencies to ensure permits for waters and wetlands are issued in a timely fashion and commitments are minimized the those necessary to the specific project. Public Engagement Dokken has extensive experience in public involvement and meetings, which has proven to be an invaluable tool for our past clients by providing a comprehensive public outreach program that goes above and beyond what is required under State and Federal environmental guidelines. By including the public in the process and encouraging public input on our projects, Dokken is able to identify potentially controversial issues and provide responses in the form of design alternatives in the project planning process prior to project's going to bid and construction. Constructability Review Dokken has read the Constructability Analysis Memo, dated 4/30/19, we acknowledge that current plans are in draft format. We understand what it will take to complete the PS&E Package in preparation for construction to achieve a biddable and buildable plan set that minimizes costly Construction Change Orders. We are prepared to provide a set of Responses to Comments provided via this Constructability Analysis Memo as a first order of work, to gain concurrence on the design approach before proceeding. Optional Tasks in Scope of Work In addition to the key project issues explained herein we wanted to utilize this section of our proposal to identify potential items of work that may be needed to complete this project, beyond those discussed in the RFP. We have included these additional items in our scope of work (i.e. work statement) and elaborated on why they have been included as optional tasks.

Our team will provide the resources and tools necessary to deliver this project with minimal oversight from the City staff. LINES OF COMMUNICATION It's critical that the project team receives confirmation of the scope, budget and schedule from the City' Project Manager. This review allows all parties to understand the project scope and schedule and the submittal milestones. In addition to monthly project team meetings, Dokken Engineering will keep the City Project Manager aware of progress through weekly emails and team conference calls. This approach allows the City Project Manager to provide any required input thoughout the project development process 0 @ �„ Page 1 14 L' N G IN E N It NC! SIERRA HIGHWAY BRIDGE NEW ENGINEER OF RECORD TO ADDRESS CONSTRUCTABILITY REVIEW PROPOSAL # EN G-20-21-S3038 SCHEDULE AND BUDGET CONTROL In order to manage the three interdependent elements found in every project — scope, schedule, and budget — it is necessary to implement a sustainable project control methodology. Charles, our Project Manager, will develop and implement the project controls plan. The plan outlines the procedures for conducting work, managing project resources and reporting project status and progress. The project management tools identified on the right assures on time and within budget project deliverables. These tools will enable Charles to provide a systematic approach to deliver any project. All project participants, including the City and Dokken Engineering Team, will be aware of the project status in order to make informed management decisions. Our tools and system are designed to respond to these requirements. Dokken Engineering prepares and maintains project schedules for every project. The schedules are monitored and staffing adjusted to meet milestones. Performance is monitored through quality control checks, review of actual versus planned progress, completion of action items prepared after meetings, monthly invoicing, and progress reporting. Dokken Engineering will use the City standards and formats, making invoice review streamlined and familiar to the City. For our team, quality is not just a priority, it is a core value. Dokken Engineering has found that the best way to control budget is to ensure the project schedule is followed. This method avoids costly over- runs and extended production times. The key to preserving budgets is to start on time, get it right, and submit the deliverable on time. Utilizing the same design working group from the beginning of the project to the end ensures consistent thought and engineering practice, while eliminating wasteful hours spent "getting familiar" with a project. 21 The MS Project Schedule will be supplemented with a deliverables schedule that identifies all project deliverables and submittal dates. The deliverables schedule is a critical project management tool because it specifies what is being delivered to the client and when it is to be submitted. The deliverables schedule will be updated monthly and submitted as part of the monthly invoice to report on the status of completed, in -progress and upcoming deliverables. The combination of the budget and schedule showing task durations and sequencing will enable us to produce a time - phased budget. With a time -phased budget and a work -based method of measuring progress, a reliable comparison on planned versus actual can be made. PROJECT COMMUNICATION As an extension of the City staff, Charles and his team will use a suite of communication mechanisms to keep the City informed and to maintain the project schedule. The following diagram identifies the key communication methods to deliver this project. 0 @ �„ Page 1 15 L' N G IN E N It NC! SIERRA HIGHWAY BRIDGE NEW ENGINEER OF RECORD TO ADDRESS CONSTRUCTABILITY REVIEW PROPOSAL # EN G-20-21-S3038 Dokken Engineering has long-standing history of delivering projects with multiple team members and stakeholders, and we have established communication protocols that all team members understand. We host weekly internal team conference calls to track progress and keep everyone current on project status and recent decisions that affect their awareness and productivity. Our number one goal when working with our clients is successful project delivery. We identify risks early in the process and develop ways to mitigate these risks. We work closely with our clients to keep them informed on the status of their project and any pending decisions, and we are extremely responsive to their needs. QUALITY CONTROL/QUALITY ASSURANCE Dokken Engineering and our Team members are committed to the City of La Mesa in delivering project documents whose quality exceeds the Industry standards. Quality is not just a priority; it is one of our core values. From the project outset, QA/QC procedures will be implemented in accordance with the project Scope of Work. Our procedures incorporate continuous product review cycles during plan development, as well as a series of formal review procedures completed for major project deliverables. The review of deliverables needed to satisfy the QA/QC procedure is built into our proposed schedule. The flow chart below outlines our process: We take quality very seriously, as a quality plan set provides the most competitive bidding opportunities for projects and helps keep projects within their overall budgets, ultimately resulting in a high -quality project being built, on time, and with minimal or no change orders. ASSIGNED STAFF The Dokken Engineering team will be led by Project Manager, Charles Tornaci, PE.

This project originally began as part of a residential development project. When adverse economic conditions affected the developer, the City of Santa Clarita took ownership of the street improvements to complete the project. Dokken Engineering assisted the City in securing Federal funds under the Active Transportation Program (ATP), and helped the City through the required Federal processes and documentation required by the ATP grant. Sierra Highway is a principal arterial in the City of Santa Clarita and is an un- relinquished part of the State Highway System. Dokken Engineering worked with Caltrans to identify that work within Caltrans Right -of -Way was under $1 million dollars, allowing the City to develop the improvements under a Caltrans Encroachment Permit, with oversight from Caltrans to approve the widening and pedestrian bridge. The widening of Sierra Highway provided an additional dedicated right turn lane to serve the high volume of westbound to northbound turning vehicles and Other key project components included multiple agency coordination (Caltrans District 7, Caltrans Local Assistance, Caltrans Structures Headquarters, and City of Santa Clarita), grant assistance, staged construction, detour routing, utility coordination/relocation, and special non - fracture critical design of the steel box -truss pedestrian bridge to meet Caltrans design and maintenance requirements while also matching the aesthetics of other pedestrian bridges within the City.

The McBean Parkway Bridge crosses over the Santa Clara River and is approximately 0.25- miles north of the Magic Mountain Parkway and McBean Parkway intersection. The main purpose of the project was to widen the McBean Parkway Bridge to its ultimate planned width and increase vehicular, pedestrian, and bicyclist mobility in the vicinity of the project site. The existing McBean Parkway Bridge consisted of seven spans of concrete slab on precast, prestressed concrete girder superstructure. The bridge carried three -lanes of southbound traffic and four -lanes of northbound traffic, with a 6- foot sidewalk on the west side and a 10-foot sidewalk on the east side. The project provided gap closure; the existing bridge has seven travel lanes and the approach roads have eight travel lanes. The reduced number of lanes across the bridge restricts traffic movement. The project widened the bridge to eight travel lanes and closed the gap in the current McBean Parkway transportation system between Magic Mountain Parkway and Avenue Scott. The project included the addition of a traffic lane and Class I bike trail to the McBean Parkway Bridge by widening the bridge on the west side. On the north end of the bridge the existing pedestrian/bicycle trails, which connect directly to McBean Parkway, were extended to cross beneath the bridge and run parallel to the north abutment, allowing for a continuous trail. Also, a concrete barrier along the sidewalk on the east side of the bridge was constructed to improve pedestrian/bicycle safety. On the west side of the bridge, a Class I path was constructed and separated from the traffic lanes by a concrete barrier.

The following is a list of sheets proposed to be submitted with the 95% PS&E Package: • Title Sheet, General Notes, Index of Plans (2) • Survey Control Sheet (1) • Typical Cross Sections (2) • Roadway Plans/Profiles (3) • Construction Details — Roadway (4) • Roadway Q's matching Bid Items (2) • Drainage Plans/Profiles, Details, & Q's (6) • Stage Construction / Traffic Handling (20) • Utility Plans with Pothole Information (3) • Erosion Control Plans with ESA Fencing (3) • Sign Plans, Details, & Q's (3) • Striping Plans, Details, & Q's (3) • Hardscape / Aesthetic Details & Q's (2) • Electrical / Bridge Lighting, Details, & Q's (3) • Retaining Wall Plans, Details, & Q's (12) • Bridge Plans, Details, & Q's (40) TOTAL Plan Sheets =109 Sub-Subtask 4.1.2: Final PS&E The Dokken Team will review and respond to any City comments from the 95% PS&E submittal. Once all comments are addressed, we will continue with the design effort to reach Final PS&E. Dokken will prepare a revised, final set of plans, construction specifications, and construction cost estimate with bid schedule. Any changed unit items or cost from the 95% submittal will be identified to the City for clarity. Dokken will review and respond to the comments on the geotechnical report, hydrology study, structural calculations, and foundation report and will prepare or coordinate preparation of final reports, studies, and calculations. When the project is complete, Dokken will provide AutoCAD files for all plan sheets via file share (MS-OneDrive) link. Subtask 4.2: Guardrail and Fencing Treatment Dokken will research local preferences as well as Caltrans' standards for guardrail and fencing and will work with City staff to incorporate the requirements. We will maintain the proposed bridge and sidewalk widths, compliant with HBP funding constraints, and will maintain the necessary roadway widths with the addition of traffic rated barriers to protect pedestrians. Dokken will produce layout sheets to show the limits of the guardrail and fencing pay items and will include those sheets with the 95% Submittal, to be updated with the Final Submittal. Subtask 4.3: Environmental Requirements Dokken will review the CEQA, NEPA, and environmental permits and assist in incorporating any environmental commitments into the project PS&E. The CEQA Initial Study with Mitigated Negative Declaration (CEQA IS/MND) and the NEPA Categorical Exclusion (NEPA CE) contain a number of environmental commitments, and it is understood that the City is currently revalidating the NEPA environmental document which may contain additional environmental commitments. Similarly, the environmental permits are currently requesting extensions, and may contain updated requirements, which will be incorporated into the plans and specifications. Dokken will review plan sheets and proposed project improvements to determine if there are any project changes not previously analyzed, in which an addendum under CEQA or a revalidation under NEPA would be necessary and can assist the City with preparation of any necessary documentation. Additionally, Dokken will assist with preparation of contract specifications to ensure environmental commitments within the CEQA IS/MND and NEPA CE are accurately and adequately conveyed to the contractor. The Dokken team will review the approved environmental document and will incorporate all requirements into the plans and specifications. The Dokken team will determine the risk level for the project site and will prepare a draft Storm Water Pollution Prevention Plan for the appropriate risk level. This Draft SWPPP will become property of the Contractor at the start of Construction and will require update and input into the statewide SMARTS system. This approach is consistent with other recent Dokken projects and comments on the Constructability Analysis Memo. Because the total disturbed area (including staging) is anticipated to exceed 1 acre, a NPDES General Construction Activity Storm Water Permit (CGP) will be required. To obtain coverage under this permit, Dokken Engineering's 0 @ �„ Page 1 30 L' N G IN E N It NC! SIERRA HIGHWAY BRIDGE NEW ENGINEER OF RECORD TO ADDRESS CONSTRUCTABILITY REVIEW PROPOSAL # EN G-20-21-S3038 Qualified Stormwater Developer (QSD) will prepare a draft Storm Water Pollution Prevention Plan (SWPPP) for the City. Preparation of the SWPPP will involve the following tasks: • Documenting the existing site conditions and proposed project information, including the total disturbed and percent impervious area of the project site, and preparing a project information exhibit. • Calculating the risk level classification of the project. • Identifying the sources that could add pollutants to storm water discharges or could result in non -storm water discharges. • Selecting risk level appropriate Best Management Practices (BMPs) that will control each of the identified pollutants. • Preparing Water Pollution Control Drawings. • Identifying the required construction site monitoring efforts and, dependent on risk level, preparing a monitoring and sampling exhibit. • Integrating appropriate post -construction storm water BMPs. • Developing a maintenance, inspection, and repair program. • Assembling the required supporting documentation and reporting forms as Attachments/Appendices. A Preliminary Draft SWPPP will be provided to the City for review and comment. Upon receipt of City's comments, Dokken will make the necessary modifications to the SWPPP and prepare a Final Draft SWPPP to provide to the project Contractor for finalization and implementation. It is assumed that all permit fees will be paid directly by the City. Dokken will provide QSD services to handoff to the project construction Contractor. Subtask 4.4: Plan Approvals and Permits The Dokken team will coordinate and track timelines required for all plan checks including Engineering Services, Traffic, Building & Safety, Environmental Services, and any outside agencies needed for construction permits. Dokken will provide a final set of approved plans, specifications, and estimate after all plan reviews are completed. Subtask 4.5: Bidding Dokken will assist the City in answering written questions during the biding process, attend the Pre -Bid conference, and respond to technical questions from the prospective bidders. Dokken will assist with an addendum to the PS&E package (as needed) resulting from the comments and questions from the Pre -Bid conference. Dokken will assist the City in analyzing the contractor's bids for competency and completeness and will recommend the lowest responsible bidder. Dokken will assist the City's RFP preparation for Material Testing and Special Inspection. osk 4 Deli✓erobles.. 95% and Finol PS&Esubmittols feoch. (r) holfsi7e sets on I I°x17" and digi of file.

TASK 5: CONSTRUCTION SUPPORT — OPTIONAL TASKS Dokken will provide a cost proposal for construction engineering support services during the construction phase to address any design concerns on an as -needed basis and we understand this to be an optional task. Subtask 5.1: Construction Support The Dokken Team will attend contractor progress meetings as requested by the City, attend regular jobsite meetings and inspection visits, respond to request for information, review shop drawing submittals, revise the construction documents (as needed), analyze the City on contractor change order requests, prepare construction correction notices as needed, and prepare the punch list for the contractor. Dokken will implement and/or ensure compliance with measures of the project's Mitigation Monitoring and Reporting Plan (MMRP) and Environmental Commitment Record (ECR). The MMRP and ECR are a compilation of Environmental Document commitments that the City is obligated to implement to receive project approval. Qualified Dokken staff will sign off the MMRP and ECR as each measure is complied with. Throughout construction, Dokken staff will monitor the site to ensure project proponents are complying with all MMRP and ECR measures and will coordinate with the Resident 0 @ �„ Page 1 31 L' N G IN E N It NC!

Subtask 5.2: As -Built Plans The Dokken team will acquire the daily red lined plans from the contractor and the subcontractors and will prepare the As - built drawings upon completion of the project. Final record drawings will be submitted in electronic (CAD and PDF) and hard copies. 7sk 5 Defi✓erobles As -Bulk drowings to include (1) hill i7ed se on myfor ond digitol files; C"arrnpleted '79'7RP EC R TASK 6: HYDROLOGY & HYDRAULICS — ADDED OPTIONAL TASKS Subtask 6.1: Location Hydraulic Study (Confirmation of No -Rise) The widening of the Sierra Highway over Santa Clara River will involve widening of the existing bridge and construction of a new bridge. As a result, the federal guidelines provided in Executive Order 11988 - Floodplain Management require that a Location Hydraulic Study and Floodplain Evaluation Report Summary be prepared in support of the environmental document and is required for all Federally funded projects. These studies include a hydraulic analysis that will be performed to evaluate the impact of the proposed improvements on the floodplain during 100-year flood conditions. An existing condition hydraulic model will be obtained from the LA County Flood Control District or Federal Emergency Management Agency. Any existing studies previously compiled for the project will also be obtained and reviewed for their reuse or amendment. Dokken will review the existing model and update as necessary to reflect current conditions. Once verified and updated, the existing condition model will be used to create a Post Project model that reflects the preferred bridge improvements. The results of the model will be assessed to determine the impact of the proposed project on the hydraulic conveyance of Santa Clara River as well as the risk to floodplain values and adjacent properties. Dokken will prepare a Draft Location Hydraulic Study and Floodplain Evaluation Report Summary to discuss the results of the analysis and compare the impacts/risks of each project being considered. The study will include a discussion of the following items, commensurate with the significance of the risk or environmental impact: a) The risks associated with implementation of the action. b) The impacts on natural and beneficial flood -plain values. c) The support of probable incompatible flood -plain development. d) The measures to minimize flood -plain impacts associated with the action. e) The measures to restore and preserve the natural and beneficial floodplain values impacted by the action. f) An evaluation and discussion of the practicability of alternatives to any longitudinal encroachments. g) Evaluation and discussion of the practicability of alternatives to any significant encroachments or any support of incompatible floodplain development. This draft document will be submitted to the City and Caltrans for review. Comments on the draft report will be addressed and the Location Hydraulic Study will be updated and finalized. Subtask 6.2: Bridge Design Hydraulic Report (Scour and Hydraulic Analysis) Dokken will utilize the existing and proposed condition hydraulic models prepared for the Location Hydraulic Study to conduct a detailed hydraulic analysis for the selected project alternative. The objective of this analysis will be to evaluate the freeboard, overtopping, and stage increases using the 50- and 100-year frequencies as required by the various agencies with jurisdiction in this project area. We will use the results of this analysis to confirm the selected structure design such that upstream and downstream impacts are reduced and/or eliminated as needed to satisfy Federal, State, and local requirements. The scour analysis will consider pier, abutment, and contraction scour. Aggradation or degradation potential will also be evaluated based on a review of any recent survey data together with historic data collected from USGS quadrangles. Based on the results of the hydraulic and scour analyses, Dokken will prepare a Draft Bridge Hydraulic Design Report to satisfy Federal, State, and local criteria. A draft report will be submitted for review by the City with the 95% PS&E Submittal, comments will be addressed, and the report will be finalized and submitted with the Final PS&E Submittal. Subtask 6.3: SUSMP for MS4/Water Quality Permit Compliance Dokken Engineering will prepare a Specific Urban Stormwater Mitigation Plan (SUSMP) in accordance with the County of LA Low Impact Development (LID) Standards Manual and the County of LA Municipal Separate Storm Sewer Systems (MS4) Permit (Order No. R4-2012-0175).
