Detailed Description of Work Consultant shall provide planning, design, and environmental services to the Bay Area Toll Authority (BATA) for completing a Streamlined PSR/PDS, PEAR and the Project Approval/ Environmental Document (PA/ED) for the I-580 Shoulder Running Lane and Bi-directional Bike Lane Project (Project) on the Richmond San Rafael Bridge in Marin and Contra Costa counties. Project Description.. The proposed bi-directional bike lane on the upper deck of the RSR bridge using the right shoulder would connect bike paths from Contra Costa to Marin. Bike lane would start at the toll plaza on the Contra Costa side and end at San Quentin/Main St off-ramp on the Marin side. The bike lane on the bridge deck will be behind either a moveable or a permanent barrier. The project includes the following elements: Element 1 Shoulder Running Lane (RSR Lower Deck). Element 2 Two-Way Bike Lane (RSR Upper Deck) 1

2 Provide a two-way bike lane on the upper deck of the RSR bridge using the right shoulder to connect bike paths from Contra Costa to Marin. Bike lane starts at the Marine St on the Contra Costa side and ends at Main St/Francisco Blvd off-ramp on the Marin side. Bike lane on the bridge deck will be protected from vehicular traffic traffic by either a moveable or a permanent barrier. a. Construction of a pedestrian and bicycle accommodation alternative on the Contra Costa side between the RSR bridge and Marine St interchange. The alternative will be developed during the PID and PA/ED phases and include one of these two options: Option 1) Construction of a bike/ped facility along the WB shoulder of I-580 (North Side Alternative) Option 2) Construction of a bike/ped facility along the EB shoulder of I-580 (South Side Alternative). This option will require relocation of the existing retaining wall further away from the edge of travelway along the I-580 EB from Scofield Ave crossing to the Marine St off-ramp, and excavation of a large amount of soil behind the wall. It is believed that this soil is contaminated and will require special handling. All improvements are proposed to be within Caltrans right-of-way. Project scope does not include any widening or modifications of the RSR bridge structure except for the approach structure at the east end of the bridge (Contra Costa side). PHASE I PROJECT STUDY REPORT/PROJECT DEVELOPMENT STUDY 1.4 Provide agency coordination Consultant shall perform coordination with Agencies as required for project development. Coordinate planning and design effort with team members, including the following: Caltrans Affected utility companies TAM CCTA FHWA Environmental resource agencies (as required) San Francisco Bay Conservation and Development Commission (BCDC) Various cities along the corridor Bicycle Coalitions and Advisory Groups Private property owners such as Chevron Agency coordination tasks include holding one-on-one discussions or meetings with those agencies, seeking input on proposed alternatives and designs, defining impacts and developing mitigation plans, investigating regulatory requirements and expectations of stakeholders for the PA/ED and design phases, and evaluating implementation plans. 2

3 Task 2.0 Prepare PID Attachments Bike Lane Alternatives The scope of this project assumes the following alternatives for the bike lane: East of Richmond San Rafael Bridge Toll Plaza a) Bikes will continue to be allowed on the shoulder of the eastbound direction of I-580 from the RSR bridge to the Marine St off-ramp during the hours when the shoulder running lane is not in operation. b) A shuttle will be provided to transfer bicyclists in the eastbound direction from the RSR bridge to the Marine St off-ramp when the shoulder running lane is in operation. c) Consultant shall evaluate widening the freeway in the westbound direction to accommodate a two-way bike lane from the existing bike lane at Marine St/I-580 WB onramp to the proposed upper deck bike lane on the RSR Bridge. This will include widening of the Scofield Avenue overcrossing. If consensus is reached to include this concept into the preferred project alternative, this two-way bike lane will replace the shuttle concept and the bikes on shoulder in the eastbound direction. d) No build Alternative. West of Richmond San Rafael Bridge Toll Plaza a) The build alternative will include allowing the bicycles on the upper deck of the RSR Bridge from the toll plaza to the San Quentin off-ramp. The bike lane will be behind either a moveable or permanent barrier using the right shoulder. b)no build Alternative Alternatives Development During the PSR/PDS phase, Consultant shall develop the agreed upon alternative for the project with the ultimate goal of project approval. The project will be developed to produce preliminary striping plans, approximately 15% geometric horizontal and vertical design at any locations requiring geometric modification, utility base maps with key conflicts identified (if any), design exceptions identified, preliminary right-of-way needs identified, 30% level typical cross sections, and cost estimates. In addition, Consultant shall conceptually evaluate a full standard alternative that meets Caltrans design standards and prepare a conceptual cost estimate for such alternative and briefly describe the right of way and environmental impacts associated with this alternative. It is assumed that developing detailed geometric plans for this alternative will not be required and therefore are not included in this scope of work. 2.6 Six-Page Cost Estimate Consultant shall prepare a six-page cost estimate in Caltrans format for the build alternatives (preferred build alternative and the full standard alternative). This estimate will include costs 3

4 associated with both the shoulder running lane and the bike lane. Operational costs will include costs to open and close the shoulder running lane, operate the bike shuttle (if included in the project), and moving the barrier on the upper deck if a moveable barrier option is selected. The cost estimate will be developed to provide a detailed breakdown of the capital civil work, including power and communication costs for the Electronic signage. It would also include the cost of support needed for the PA/ED, PS&E and construction phase of the project Viable Alternative Selection Consultant shall prepare an alternative comparison and alternative summary for each alternative studied to provide BATA with tools to uniformly assess various alternatives. Consultant shall also summarize how each alternative ranks relative to other alternatives in a decision matrix or matrices to facilitate BATA and stakeholder selection of alternatives for documentation in the PSR/PDS. Task 3.0 Project Study Report/Project Development Study Consultant shall work with BATA and Caltrans to produce and obtain approval of the PSR/PDS document. Two Build Alternatives (One preferred and one full-standard alternative) and one No-Build Alternative will be identified in the PSR/PDS leading to the selection of the preferred alternative to be carried forward into the Project Report/Environmental Document phase. The PSR/PDS will follow the format and content requirements of the streamlined PSR/ PDS as defined in Caltrans Project Development Procedures Manual (PDPM), Appendix S. PHASE II PROJECT APPROVAL AND ENVIRONMENTAL DOCUMENT Task 4.0 Preliminary Engineering 4.9 Traffic Analysis Consultant shall provide travel forecasting and traffic operational analysis services to support the PSR/PDS and PA/ED phases. This will include preparation of a Traffic Operations Analysis Report (TOAR). The following scope of work and associated budget assumes the following:.. Westbound Bike Path and RSR Bridge The proposed westbound bike path will be a separate path that uses the existing shoulder across the bridge. The scope is predicated on the number of vehicle lanes/geometries not changing on westbound I-580 including the toll plaza approach, the toll plaza, the merge between the booths and the bridge, as well as across the bridge and west through the Sir Francis Drake Boulevard interchange. Analysis will be conducted for the westbound weekday AM peak period only. In addition to existing conditions, analysis will be conducted for two future horizon years: opening day (2015) and design year (2035). 4

5 The study/analysis area will include the westbound segment of I-580 approaching the Toll Plaza, through the Toll Plaza and across the bridge to the Main Street (i.e., San Quentin interchange). A deterministic model will be developed using spreadsheets to establish delay and extent of queues and used for the operational analysis of westbound I-580. The model will encompass the entire study segment and will include the freeway mainline and the toll plaza area as well as local interchange ramps if necessary. A deterministic model is being proposed under the assumption that the westbound I-580 vehicle lane geometries will not change with the project. The deterministic model will cover the 4-hour weekday AM (6:00 AM to 10:00 AM) peak period. The Existing Conditions model will be calibrated to observed 2014 conditions. The model s throughput volumes and delay through the toll plaza will be calibrated to within Caltrans Guidelines. Queues will also be compared visually. For the TOAR, two alternatives (No Build and Build) will be analyzed. Subtask Traffic Operations non-recurring incidents for westbound Bike Path on Bridge In addition to establishing the impact of the westbound Bike Path on AM peak period operations, Consultant shall review INRIX data to identify non-recurring incidents on westbound I-580 across the bridge and obtain from Caltrans incident reports including time and duration. Consultant shall summarize the incidents and identify using deterministic tools the level of delay and extent of congestion associated with a typical incident as well as the likely number of incidents during peak periods of congestion. Consultant shall then use the deterministic model to establish the level of impact from non-recurring incidents when the shoulder is unavailable for breakdowns and other temporary conditions. The results will be documented in a technical memorandum for use by others in a preparation of the Traffic Safety Analysis Report. Subtask Westbound Bike Path on Bridge Consultant shall review the 2007 Draft PSR and 2012 report to identify updates required and gaps in documentation necessary for project approval. Consultant shall provide relevant updates to design guidelines and criteria based on 2014 best practices, including Accommodating Bicyclists and Pedestrian at Interchanges (forthcoming ITE best practice), and conduct several site visits with agency and stakeholder representatives to discuss path routing, alignment, and design. Specific stakeholder outreach will at a minimum include the Marin County Bicycle Coalition, East Bay Bicycle Coalition, Trail for Richmond Action Committee (TRAC), City of Richmond, and other relevant advocacy groups. Consultant shall assist in an iterative review process of design concepts. Consultant shall document work in a technical memorandum supporting the PSR/PDS and the Project Report. 5

6 Task 6.0 Project Report/Project Approval 6.9 Advance Planning Study/Structural Analysis Consultant shall prepare the Advanced Planning Studies (APS) for the following: 1) Widening of the Scofield Ave bridge either to the North or South Side of the bridge. 2) Widening approximately 1000 of the eastern end of the RSR bridge (Richmond touchdown) to accommodate the bi-directional bike lane. The APS will be prepared in Caltrans format using Caltrans Office of Special Funded Project (OSFP) Memo 3-2 and Caltrans Memos to Designers (MTD) 1-8. The Design Memo will have sufficient information that can be used in developing a preliminary construction cost estimate. No quantitative seismic analysis will be performed on the existing bridges, including the Richmond-San Rafael Bridge. The APS will include plans, design memo and cost estimate for each structure. Consultant shall provide the following services: For the eastbound PM peak shoulder running lane: Conduct Data collection and review of available bridge plans and as-built drawings Conduct Windshield Survey type site visit Conduct Preliminary review of existing bridge superstructures Conduct Preliminary fatal flaw type review of typical bridge superstructures to evaluate if the existing bridge superstructures are capable of carrying a third lane of eastbound traffic Attend one coordination meeting Prepare Narrative of structural findings related to the Eastbound PM Peak Hour Lane and recommendations for further areas of study for inclusion in the project report For the bike lane accommodation on the Contra Costa side: Conduct data collection and review of available bridge plans and as-built drawings Conduct evaluation of widening options, including cantilevering a bike lane off the existing structure Attend one coordination meeting Conduct one site visit with Chevron Prepare APS drawing and square foot estimate for new widening For the bike lane on upper deck: Conduct data collection and review of available bridge plans and as-built drawings Conduct evaluation of widening options of the eastern end of the bridge 6

7 Review of recommended barrier types/systems for providing separation between vehicles and bicyclists in the 2007 PSR Review possible modifications needed for outside railings Confirm findings from APS prepared with the previous PSR Attend one coordination meeting Prepare an APS that covers the new widening of the bridge eastern section Prepare a separate narrative of structural findings (in the form of a technical memo) related to the addition of a bike lane and potential impacts to the bridge and recommendations for further areas of study for inclusion in the Project Report. Assumptions: The APS scope does not include preparing an APS for reconstruction of the retaining walls along Eastbound I-580 on the Contra Costa side. If the final selected alternative would require reconstruction of any of these walls, a separate scope and fee estimate for preparing the necessary APS and Structure Preliminary Geotechnical Report (SPGR) would be provided. It is also assumed that APSs will not be needed for other standard retaining walls or culvert extensions. All shoulder running lane overhead signs will be post mounted and no signs will be placed on the Overcrossings. Design of overhead sign structures will meet the criteria established in the Caltrans Standard Plans and additional structural design work is not required. The only widening of the RSR Bridge that would be required is the widening of approximately 1000 of the eastern end of the bridge to accommodate the bidirectional bike lane. No additional widening or modification of the truss or the trestle section of the RSR Bridge is required. Task 9.0 Public Outreach Consultant shall conduct outreach throughout this phase of the project to keep the public informed of current project status, involve key stakeholders, educate the public on the benefits of the proposed project, and fulfill CEQA/NEPA requirements for public outreach. Before outreach begins, Consultant shall draft a brief communications plan that will outline key stakeholders that may require specific outreach (such as the City of Richmond, the City of San Rafael, the East Bay Bicycle Coalition, the Marin County Bicycle Coalition, Chevron, San Quentin State Prison, Contra Costa Transportation Authority and the Transportation Authority of Marin). The plan will also develop key messaging during outreach, such as the use of shoulder running lanes and the benefits of bicycle pedestrian access on the Richmond-San Rafael Bridge. Outreach will include the production of one fact sheet (to be updated quarterly) that explains the scope, timeline, cost, and benefits of the project. Consultant shall assist with stakeholder meetings to involve key stakeholders in the process, which will include creating a stakeholder list, invitations for meetings, and production of meetings materials. Consultant shall also host public meetings as needed to comply with CEQA/NEPA standards (we anticipate up to two public meetings during this phase of the project). Tasks would include drafting and sending 7

8 mailed and ed invitations to the public meetings, advertising in local newspapers, drafting a press release to be sent by the project sponsor, assisting with the creation of a Microsoft Powerpoint presentation, drafting and producing exhibit boards (up to 20), producing meeting materials, and writing a summary report after the meeting. This will also involve creation of an online version of the public meeting, for people to access meeting documents and provide comments online if they cannot attend a meeting in person. 8
