Solution Establish a cross-jurisdictional public entity to plan, coordinate, and advance resilience projects for flooding, sea level rise, and other water-related climate risks across an entire county Key challenge Climate risks do not align with city boundaries, but planning, funding, and delivery are often fragmented across jurisdictions Context One Shoreline was established in 2020 as an independent public agency to address the water-related impacts of climate change across San Mateo County. It provides a regional platform for planning, project development, funding, and coordination where no single city can address the full risk alone. Solution in practice One Shoreline advances shoreline resilience plans, creek and flood resilience projects, planning policy guidance, early warning systems, and multi-jurisdictional project development across the county. Its work includes Brisbane, the southern Bayside cities, San Bruno Creek, and other shoreline and flood-prone areas. Impact / outcome County-wide agency (since 2020) advancing shoreline, creek and flood resilience projects across San Mateo County. Next steps Advance multi-jurisdictional shoreline resilience plans, develop future-conditions guidance for public infrastructure, build funding-ready project pipelines, and test links between property-level risk reduction and improved insurability.
