Coastside Patrol Bureau

The Coastside Patrol Bureau provides law enforcement services for over 60% of San Mateo County, including the City of Half Moon Bay. Due to this vast area, the Coastside Patrol Bureau has two substations that provide a variety of services to the community. 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 or night, for any emergency.

In addition, there are two full-time Community Policing deputies that are assigned to the entire San Mateo County Coast. The primary responsibility of these deputies is to address the needs of the community. We encourage the public to voice their concerns to the Sheriff's Office. The Community Policing staff work on all problems within the community; not only law enforcement issues but all issues dealing with the quality of life on the coast.
