## History

Bay Point was previously known by several names, including Bella Vista and, until 1993, West Pittsburg. An election was held in 1993 to vote on renaming the community Bay Point, reviving a historical name used in this area. "West Pittsburg," the former name, was sometimes confused with the western unincorporated section of Pittsburg, California. Bay Point is similarly unincorporated.

### Ambrose Park annexation

The neighboring City of Pittsburg annexed Ambrose Park in July 2008. Administrative control remained with the Ambrose Parks and Recreation District, which had owned and operated the site and its facilities since 1946. The move was designed to bring Pittsburg's greater development funding and general resources to a joint project to replace the long-time swimming pool facilities at the park. The new Ambrose Aquatic Center opened on July 4, 2016. By population, about 20% of the Ambrose Parks and Recreation District is within Pittsburg City limits. Ambrose Park features picnic, tennis, basketball and hiking, and picnic facilities in 12.3 acres of unincorporated land at 125 Memorial Way, immediately adjacent to the City of Pittsburg. It was a gift to the community from the local Enes family in 1947.
