Climate Adaptation Plan for Sea Level Rise (Subregional Shoreline Adaptation Plan)

Climate AdaptClimate Adaptation Plan Community Workshopation Plan Community Workshop #1

The City needs your feedback to shape how our community prepares for sea level rise. Your input will help shape a coordinated, actionable plan that protects our community, critical infrastructure and natural resources while preparing San Mateo for future climate impacts. 

In 2024, the City of San Mateo obtained a Caltrans Sustainable Transportation Planning Grant to create a Climate Adaptation Plan for Sea Level Rise (Project/Plan), which will fulfill the new requirements of Senate Bill 272 and the San Francisco Bay Conservation and Development Commission’s (BCDC) Regional Shoreline Adaptation Plan (RSAP) to prepare a Subregional Shoreline Adaptation Plan (Subregional Plan) for the City. The initiative is supported by funding from the California Department of Transportation (Caltrans) Sustainable Planning Grant Program and will meet new regional requirements for shoreline resilience planning. San Mateo is among the first agencies in the region to formally initiate a plan aligned with RSAP requirements. BCDC has issued an Initiation Notice recognizing the City’s effort. 

Existing Conditions Report

The City of San Mateo’s Subregional Shoreline Adaptation Plan (SSAP) will be organized into seven elements: A – Planning Process; B- Existing Conditions; C- Vulnerability Assessment; D- Adaptation Strategies and Pathways; E – Land Use and Policy Plan; F – Project Implementation and Funding Plan; and G – Project List. The project team completed the Existing Conditions report, that documents current conditions along San Mateo’s shoreline, as required by BCDC’s RSAP Guidance. The report provides a foundation for the City’s Subregional Shoreline Adaptation Plan by identifying existing plans and policies, describing shoreline and habitat conditions, and evaluating the people, infrastructure, services, and land uses that may be vulnerable to sea level rise and coastal flooding.
