About this area:
Contra Costa County belongs to one of California’s busiest urban centers—the San Francisco Bay Area. There are nine counties contributing to the economy of the Bay Area: Contra Costa, Alameda, Marin, Napa, Santa Clara, San Francisco, San Mateo, Solano and Sonoma. While there is a tremendous amount of growth and development in Contra Costa County, much of the land is still rural, providing many recreational opportunities. The western and northern area shorelines are highly industrialized, while the interior sections are residential, commercial and light industrial.
