The BART Board approved the name
Pleasant Hill in December 1965. Service at the station began on May 21, 1973.
AC Transit bus service began in Pleasant Hill on December 8, 1975, with Pleasant Hill station as a hub. The service was taken over by
County Connection in 1982. By 2002, Pleasant Hill had the most parking spaces of any BART station, with 3,398 spaces in a garage and surface lots. Walnut Creek station was originally intended to serve the surrounding low-density suburban neighborhoods. However, apartment complexes and mid-rise office buildings were soon constructed nearby. County plans approved in 1983 and 1984 initiated the concept of a "transit village" of mixed-use
transit-oriented development around the station. Planning began around 2001 to replace the surface parking lots with a transit village. Construction of mixed-use buildings (Block A and Block B) began the next month. The two buildings, as well as a $12 million footbridge carrying the
Iron Horse Regional Trail over Treat Boulevard, were opened in October 2010. On September 23, 2010, the BART Board voted to change the station name to
Pleasant Hill/Contra Costa Centre to reflect the name of the transit village. The name change was supported by the transit village developer and the Contra Costa County Redevelopment Agency, but opposed by the city of Pleasant Hill. The Contra Costa County Redevelopment Agency and the developer paid the $413,800 cost of changing station signage and system maps. In March 2024, the BART Board approved plans to change the approved office building (Block D) to residential use. == References ==
