Current City Practices Current Stormwater Projects Redwood City is advancing several major stormwater projects to address aging infrastructure, flood protection, water quality, and regulatory compliance. Key efforts include rehabilitation of the Bradford and Price stormwater pump stations, early planning for the Redwood Shores Sea Level Rise Protection Project, and watershed studies focused on Redwood Creek. The City budgets for targeted storm drain upgrades, annual maintenance of tidal-adjacent channels, and green infrastructure projects such as the Red Morton Stormwater Capture Project. Additional investments include trash capture systems and other best management practices to maintain compliance with the Municipal Regional Stormwater Permit, which regulates stormwater discharges and requires municipalities to reduce pollutants and protect water quality. Maintenance Practices The City’s stormwater system is maintained by the Public Works Services Department through a combination of routine inspections, preventive care, and contracted support. Pump stations are serviced regularly, with wet well cleaning and debris removal timed to storm season demands. Catch basins, channels, and culverts are cleared annually and after major storms, while levees receive semi-annual inspections to ensure integrity and access. The City also contracts for annual lagoon maintenance in Redwood Shores and manages bioretention facilities on a five-year cycle, coordinating with property owners where green infrastructure is privately installed. Funding Sources Stormwater projects are financed through a mix of local capital and operating funds as well as regional, state, and federal grants. The Capital Outlay Fund, supported by the Utility Users Tax, provides limited internal funding for stormwater infrastructure improvements, while Federal Emergency Management Agency (FEMA) and Congressional Community Project Funding have supported major rehabilitation projects. Additional grants have been secured from the California Natural Resources Agency, Environmental Protection Agency (EPA), and the City/County Association of Governments of San Mateo County. Routine maintenance relies primarily on Public Works Services’ operating budget, but without a dedicated stormwater utility or revenue stream, the City continues to depend on one-time allocations and competitive grants for larger scale projects. Stormwater Challenges Redwood City’s stormwater system faces significant challenges related to aging infrastructure, limited capacity, regulatory compliance, and increasing climate risks. Localized flooding occurs due to tidal backflow from the Bay, undersized and/or aging pipes, and sediment or debris accumulation. These problems are compounded by sea-level rise and shallow groundwater emergence, which are expected to increase flood risk in low-lying neighborhoods such as Redwood Shores, Friendly Acres, Centennial and 11.A. - Page 2 of 53 433
