Mutual Aid

California’s Law Enforcement Mutual Aid Program is intended to augment local resources that have become overwhelmed as a result of unplanned circumstances requiring an emergency response.

The Operational Area Mutual Aid Coordinator is the liaison to the County, Regional, State and Federal agencies for law enforcement related resource requests, to include human caused and natural disasters, civil disturbances and other significant events requiring large numbers of law enforcement personnel and equipment, including the county's Mutual Aid Mobile Field Force (MAMFF).
