Patrol Bureau

The Patrol Bureau strives to improve the quality of life in San Mateo County by providing a high level of public service and keeping communities safe through enforcement, prevention, education, and community policing efforts in partnership with communities, other governmental entities, and schools.

The Bureau is comprised of Headquarters Patrol that serves the Bayside areas; Coastside Patrol that serves all coastal beats; and the Sheriff’s Motorcycle Unit. The Patrol Bureau incorporates a strong community policing philosophy into all services and activities provided. This facilitates a sense of partnership with the communities and customers served.

The Patrol Bureau provides general law enforcement services to the unincorporated areas throughout the County, as well. Under separate contracts, it provides full police services within the Towns of Woodside and Portola Valley, the City of Half Moon Bay, the City of San Carlos, as well as Eichler Highlands, in unincorporated San Mateo.

The School Resource/Community Policing Unit is attached to the Patrol Bureau and provides Drug Awareness and Resistance Education, Gang Resistance Education, and Awareness Training classes at elementary and middle schools. This Unit also conducts child safety seat inspections and Sober Prom programs for Woodside and Half Moon Bay High Schools.

The Coastside Patrol Bureau is responsible for law enforcement activities for over 60% of San Mateo County. Because of the large area, Sheriff Horsley found it to be in the best interest of the community to establish a practical and efficient substation located in Moss Beach.

The Moss Beach Substation offers the largest law enforcement facility on the coast. Its' location is ideal since it is easily viewed from State Highway 1. Staffed with 27 full time deputy sheriff's, four Sergeants and one Lieutenant, the Bureau is staffed at a level to consistently supply enforcement resources any time of day, for any emergency.
