The Bay Area Region

The Bay Area region encompasses Alameda, Contra Costa, Marin, Napa, San Francisco, San Mateo, Santa Clara, Solano, and Sonoma counties.

How We Govern

ABAG is part regional planning agency and part local government service provider. We perform a broad range of activities for our member cities, towns and counties—and ultimately for everyone in the Bay Area.
