Who We Are

The Bay Area Municipal Stormwater Collaborative (BAMSC) is an informal collaboration of the municipal stormwater programs in the San Francisco Bay Area representing 103 agencies, including 88 cities and towns, 8 counties, and 7 special districts. BAMSC is focused on regional challenges and opportunities to share information, collaborate, and advocate for permittees working to improve the quality of stormwater flowing to our local creeks, the Delta, San Francisco Bay, and the Pacific Ocean. BAMSC was formed following the dissolution of BASMAA as a non-profit in 2021. Click link below to learn more on BASMAA’s history.
