The agreement provides for the responsibility of each party, as well as the cost split. STAFF RECOMMENDATION: Adopt the Resolution Approving the Cooperative Agreement with Alameda County Transportation Commission for the Green Stormwater Infrastructure Project. FINANCIAL IMPACT: As approved in the 2022-2027 Capital Improvement Program (CIP), the total budget for the Green Stormwater Infrastructure Project, CIP No. ST0121, is $2,153,375. The estimated consultant cost for the preliminary engineering, environmental clearance and permitting, and final design for the Green Stormwater Infrastructure - Iron Horse Trail, South of Amador Valley Boulevard portion of the project is $314,250. Alameda County Transportation Commission will fund and reimburse the City 75% of this amount. A subsequent agreement covering the costs and funding for the construction phase and long-term operation and maintenance will be brought to the City Council for consideration at a future date. DESCRIPTION: The 2022-2027 Capital Improvement Program (CIP) includes the Green Stormwater Infrastructure Project (CIP No. ST0121, Attachment 3), which provides for planning, design, and Page 1 of 2 58 construction of various citywide projects that will improve water quality and provide other environmental benefits in accordance with the Green Stormwater Infrastructure Plan, which was approved by the City Council on June 18, 2019. One of the projects included in this CIP is the Green Stormwater Infrastructure - Iron Horse Trail, South of Amador Valley Boulevard project (GSI Project) to treat stormwater runoff from the adjacent neighborhoods prior to discharge into South San Ramon Creek and Alamo Creek. The preliminary engineering for the GSI Project began in September 2022. Alameda County Transportation Commission (Alameda CTC) is the lead agency implementing the Project Approval and Environmental Document, Plans, Specifications & Estimate, and Right -of - Way phases of the SR84 Expressway Widening and SR84/I-680 Interchange Improvements project (Alameda CTC Project), including the improvements to meet stormwater treatment and flow control requirements specified in the San Francisco Bay Regional Water Quality Control Board (RWQCB). Caltrans and the RWQCB have approved off -site stormwater treatment and flow control for the Alameda CTC Project. The City's GSI Project can accommodate the requirements of the Alameda CTC Project by incorporating modifications to increase the tributary area of impervious surface and incorporate flow control, so long as Alameda CTC reimburses the City for the additional costs. The proposed Cooperative Agreement covers the preliminary engineering, environmental clearance and permitting, and final design phase of the combined project. Consultant costs for this phase of the project are estimated at $314,250. The Cooperative Agreement establishes that Alameda CTC funds 75% of these costs, participates in project review, and agrees to future agreements for project construction and long-term project maintenance. Staff will return to the City Council with subsequent agreements or amendments for the construction phase and long- term operation and maintenance for the City Council's consideration.

The GSI Plan and associated implementing projects, as well as trash load reduction requirements, are mandated by the Municipal Regional Stormwater Permit (MRP). Projects include: stormwater full trash capture device installation throughout the City, and construction of GSI associated with phase one of the Iron Horse Nature Park and Open Space Project. GSI planning and planning for the installation of trash capture devices began in FY2021-22. This project is funded by a General Fund Reserve set aside for this purpose. ANNUAL OPERATING IMPACT: To be determined. On -going operations and maintenance (O&M) expenditures for installed facilities are required, but may be equal to current maintenance expenditures, particularly for retrofit and replacement projects.
