Who We Are

The Bay Area Stormwater Management Agencies Association (BASMAA) was formed in 1990 as an informal association under a Memorandum of Understanding and was reformed as a 501(c)(3) non-profit organization in 2009. BASMAA was comprised 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. BASMAA focused on regional challenges and opportunities to improve the quality of stormwater flowing to our local creeks, the Delta, San Francisco Bay, and the Pacific Ocean.
