Contra Costa County is part of the greater San Francisco Bay area, in the north section of the East Bay region. The county is literally named “opposite coast” in Spanish, as it is located across the bay from San Francisco. Contra Costa County was established in 1850, one of the 27 original counties founded the same year as California statehood. Martinez became the county seat in 1850, although the town lacked the necessary 200 voters to incorporate as a city until 1876. The city was home to naturalist and Sierra Club founder John Muir from 1880 until his death in 1914. Contra Costa County is bordered by Solano County to the north, San Joaquin County to the east, and Alameda County to the south. The county, primarily suburban, is home to the cities of Antioch, Brentwood, Concord, Richmond, San Ramon and Walnut Creek, all with populations greater than 50,000.
