Alamo is an unincorporated community and census-designated place (CDP) in Contra Costa County, California, in the United States. It is a suburb located in the San Francisco Bay Area’s East Bay region, c. 28 miles (45 km) east of San Francisco. Alamo is equidistant between the city of Walnut Creek and the incorporated town of Danville. As of the 2010 census, the population was 14,750. The community of Alamo is well known for its bucolic country feel, notable residents, and its affluent lifestyle with the median home price being $1,890,000.
Alamo (from the Spanish álamo, “poplar”) was named for the poplar trees that lined San Ramon Creek.
As an unincorporated community, Alamo does not have a government of its own. Police services are provided by the Contra Costa County Office of the Sheriff. Fire and EMS services are provided by the San Ramon Valley Fire Protection District.
Alamo has a median household income of $140,561 (as of 2011). In August, 2007, a group of citizens launched a new initiative to incorporate the community, the latest in a series of attempts that go back to the early 1960s or before. Previous failed Alamo incorporation efforts always included parts of other nearby unincorporated areas: Alamo-Danville (1964) and Alamo-Danville-San Ramon (1976). This latest Alamo incorporation effort was defeated by referendum in March, 2009.
