Our area of patrol includes some 65 different parks over a 1,750 square mile area covering all of Alameda and Contra Costa Counties. In fact, we are the largest regional park system in the United States. We also patrol over 1,200 miles of trails. Through policing contracts we also provide law enforcement services in the East Bay Municipal Utilities District (EBMUD) watershed and recreation facilities. By special agreement we additionally provide police service in the East Bay lands of the San Francisco Public Utilities Commission's watershed, and for several state owned parklands located in the East Bay.
