In 2023, the City/County Association of Governments of San Mateo County (C/CAG) received a
California Integrated Climate Adaptation and Resilience Program (ICARP) Adaptation Planning
Grant Program grant to develop and pilot the OneWatershed Framework, an equitable climate
adaptation approach focused on integrated watershed management.
Climate risks in San Mateo County include flooding due to sea level rise and extreme precipitation,
water supply stress due to hydrologic drought, emergent groundwater, and urban heat. Underserved
and vulnerable communities in San Mateo County are at disproportionate risk of climate impacts. The OneWatershed Framework brings together a collaboration of public infrastructure and water resource agencies to embark on a coordinated effort to ensure a climate reslient and equitable approach to watershed management in San Mateo County. Specifically, the OneWatershed Framework will assess the regional and shared-risk of climate change to water infrastructure and resources (sewer, water, stormwater) and develop opportunities to build adaptive capacity to climate impacts for the most vulnerable communities.
and Community-Led Plan Factsheet
The OneWatershed Framework approach will then be piloted in the San Bruno Creek Watershed. Data and results will be publicly available through the OneWatershed Dashboard, which will be integrated into the existing C/CAG GI Tracking Tool.
The OneWatershed Framework Project is supported by the Adaptation Planning Grant Program implemented by the Governor’s Office of Planning and Research.
This website will provide information on the development of the OneWatershed Framework, including planned public workshops and opportunities to provide input on the project deliverables.
