The Stormwater Roadmap is an innovative approach to system planning, allowing the City to both utilize existing data and studies and move forward with purposeful and consistent next steps by utilizing funding as it becomes available. The Roadmap will review existing data from past studies and identify data gaps, consider the impacts of climate change, both from anticipated tidal and precipitation changes, on the stormwater system, provide a sequence of tasks to complete a system-wide stormwater master plan, and identify possible funding mechanisms. Ideally, a stormwater master plan for the whole City could be funded at once, but the Roadmap will provide a path toward a holistic study that can be broken into smaller pieces to be completed as funding allows. Stormwater pump stations are maintained monthly, but rehabilitation and replacement of pumps is limited due to their high costs. Capital projects are developed based on available funding. Staff seek regional, state, and federal grants to supplement City funding. Upstream stormwater flows from multiple jurisdictions impact downstream channel conditions. All of the City’s stormwater and associated pollutants are conveyed to the San Francisco Bay. Dredging to clear sediment and other pollutants requires regulatory permits from agencies such as the Regional Water Quality Control Board and the U.S. Army Corps of Engineers, as well as specialty equipment, crews, and material disposal. The City will need to engage other agencies, including the City of San Carlos and the County of San Mateo, to develop comprehensive stormwater management and flooding mitigation solutions and obtain necessary funding. OneShoreline could be a valuable partner in this effort. The City maintains and operates the Redwood Shores Lagoon to provide additional stormwater capacity. The Lagoon Management Plan identifies best practices to meet water quality objectives set forth by the San Francisco Regional Water Quality Control Board. Localized sediment build-up will require dredging; as noted above, dredging requires significant regulatory permitting and funding. Staff continue to explore dredging opportunities for the Redwood Shores Lagoon. In recent years, staff observed increased need for algae management due to warmer weather experienced in late winter and early spring. This may be attributable to the overall effects of climate change. To support these efforts, Redwood Shores property owners pay into the Redwood Shores Maintenance Fund to support the maintenance and improvements of water channels and infrastructure. A summary can be seen in Table 4, with a preliminary estimate for recommended funds for FY 25-26. 9.A. - Page 15 of 20 500
