The Town of Corte Madera, Town of San Anselmo, and City of Larkspur, through two selected members from each council, form the Central Marin Police Authority Council. Each category of membership has an alternate member.
Overall management of the Central Marin Police Authority is the function of the Management Committee comprised of the City and Town managers. Operation of the Central Marin Police Authority is assigned to the Chief of Police.
The Central Marin Police Authority was established in January 2013 through a joint powers agreement binding the City of Larkspur and towns of Corte Madera and San Anselmo. CMPA was a consolidation between the Twin Cities Police Authority and San Anselmo Police Department to increase available resources while reducing redundancies. The Authority provides police services to about 35,000 residents in the Communities of Corte Madera, Larkspur, San Anselmo, and portions of Greenbrae.
