San Anselmo

Marin County

Heart of the Ross Valley

A creek-side town with a vibrant downtown, where the Ross Valley's residential neighborhoods and independent commerce converge

San Anselmo lies at the center of the Ross Valley in central Marin County, along San Anselmo Creek and the corridors connecting San Rafael to Fairfax and Sir Francis Drake Boulevard. Incorporated in 1907, the city developed as a railroad stop and commuter suburb for San Francisco residents. Today San Anselmo is known for its downtown San Anselmo Avenue commercial district, creek-side parks, and residential neighborhoods that form the civic core of the Ross Valley alongside Fairfax and Ross.

Indigenous / Early History

Coast Miwok communities inhabited the Ross Valley for thousands of years, establishing villages along San Anselmo Creek and tributaries flowing from Mount Tamalpais. Oak woodlands and freshwater resources supported sustainable land use patterns that shaped the valley's ecology.

Spanish missionaries and Mexican rancheros later claimed the region. American settlement brought dairy farming, logging, and eventually railroad development that anchored San Anselmo's late 19th-century growth.

Twentieth-Century Growth

Postwar suburban expansion increased housing throughout the Ross Valley. San Anselmo maintained its downtown commercial district while residential neighborhoods expanded on available hillside and valley-floor parcels. Flood events along San Anselmo Creek prompted engineering studies, creek restoration projects, and downtown building modifications to reduce future risk.

The city's identity strengthened around independent retail, community events, and civic participation in regional planning for transportation and housing.
