PREVIOUS RELATED ACTION:
On June 1, 2020, the Council approved the award of a sole source agreement with Stantec to implement the Regional Board's required Monitoring Program on behalf of the Watershed Group. On January 4, 2021, City Council approved Addendum No. 1 for an infiltration study. On August 15, 2022, City Council approved Amendment No. 2 to continue to complete the required Regional Board monitoring efforts. On May 15, 2023, City Council approved Amendment No. 3 to continue to implement the required monitoring. On June 3, 2024, City Council approved Amendment No. 4 to continue to implement the required monitoring.
DISCUSSION:
In an effort to meet the Regional Board’s requirements relating to storm water quality, for the past 13 years the Watershed Group have joined forces to comply with said requirements, and again have all agreed they would like to continue using Stantec because of their institutional knowledge of the four cities MS4 systems, understanding of the permitting needs and knowledge of the basins and tributaries within each city. Stantec is in the process of compliance needs for the group that extends over into multiple fiscal years. Due to the upcoming TMDL deadlines approaching in December, Stantec was in the process of working on a Time Schedule Order with the cities and the regional board to remain in compliance with our NPDES permit. Due to the overlap in fiscal years, staff is asking for an extension to keep the momentum of the discussions with the regional board.
At this juncture, staff is seeking approval of the final Amendment No. 5, to complete the FY 2025-26 required Regional Board monitoring and reporting activities. The City will continue to work with our neighboring cities to cost-share and share data. The attached agreement has been approved as to form by the City Attorney. This will be the final amendment to Stantec’s contract and staff will go out to bid for a new contract for FY 2026-2027.
