The County of Contra Costa embodies an area approximately 750
square miles and a population of over one million. The Sheriff’s
Patrol Division provides uniformed law enforcement services to
approximately 517,454 residents who either live in part of Contra
Costa’s 521 square miles of unincorporated land, a contract city,
or a special district such as the Town of Discovery Bay.
The Contra Costa County Sheriff’s Office maintains a network of
Station Houses, each of which is commanded by a Lieutenant, and
enables efficient provision of law enforcement services to the
163,000 residents of the unincorporated areas of the County.
Deputies assigned to the unincorporated Patrol Services Division
respond to over 600,000 citizen-generated calls and
Deputy-initiated events per year, generating over 38,000 written
Discovery Bay Sheriff’s Annex
In September 2009, the Sheriff’s Office unveiled its new annex
located on Discovery Bay Boulevard in Discovery Bay, and
introduced the community to their two new resident deputies as
well as a crime specialist. In addition, the town also christened
a new patrol car that is assigned to patrol Discovery Bay.
The resident deputies, crime prevention specialist and additional
patrol car were paid for with P6 zone funds—more than $500,000
per year earmarked for enhanced police services and collected
from residents living in the specialized P6 tax areas in
Discovery Bay West. Beginning in 2010, a new P6 Committee began
meeting to ensure that these funds are spent appropriately, and
to also provide input into future needs.
