Contra Costa County (Spanish for "opposite coast"[1]) is a suburban county in the San Francisco Bay Area of the U.S. state of California. As of the 2000 census, it had a population of 1,024,319. The county seat is Martinez. According to the U.S. Census Bureau, the county has a total area of 802 square miles (2,078 km²), of which, 720 square miles (1,865 km²) of it is land and 82 square miles (213 km²) of it (10.25%) is water. It is bounded on the south and west by Alameda County; on the northwest San Francisco Bay (San Francisco and Marin Counties); on the North by San Pablo Bay, the Carquinez Strait, and Suisun Bay (Solano and Sacramento Counties); and on the east by the San Joaquin River (San Joaquin County). Contra Costa County's physical geography is dominated by the bayside alluvial plain, the Oakland-Berkeley Hills, and Mount Diablo, an isolated 3,849-foot (1,173 m) upthrust peak at the north end of the Diablo Range of hills. The summit of Mount Diablo is the origin of the Mount Diablo Meridian and Base Line, on which surveying of much of California and western Nevada are based. The Hayward Fault Zone runs through the western portion of the county, from Kensington to Richmond. The Calaveras Fault runs in the south-central portion of the county, from Alamo to San Ramon. The Concord Fault runs through part of Concord and Pacheco, and the Clayton-Marsh Creek-Greenville Fault runs from Clayton at its north end to near Livermore. These slip-strike earthquake faults and the Diablo thrust fault near Danville are all considered capable of significantly destructive earthquakes and many lesser related faults are present in the area that cross critical infrastructure such as water, natural gas, and petroleum product pipelines, roads, highways, railroads, and BART rail transit.
