By mutual agreement, the Los Angeles County Sheriff’s Department and the forty-seven (47) local police departments within the county have agreed to provide each other with mutual aid in the event of a major unplanned event which would impact law enforcement resources. In order to best utilize mutual aid resources, the county has been divided into eight geographic areas, “A” through “H.” These areas are currently based on Disaster Management Area configurations which were redefined in the mid 1990s.
Also, within each area are LASD “contact” stations. These contact stations are typically the closest geographically located station to a particular local police department.

Area “D” Police Departments Contact Station
Arcadia PD Temple

Claremount PD Walnut
Covina PD Walnut
El Monte PD Temple
Glendora PD Walnut

Each mutual aid Area selects a local police department agency to be the “lead” police department. Glendora PD is the lead agency in Area “D”. An agency acting as the lead agency for their Area Platoon will have one (1) designated person from their department to oversee the mutual aid activities, Lt. James De Mond is the designated Law Enforcement Coordinator (LEC) with assistance from Area D, Disaster Management Area Coordinator as the Civilian Suport (CS).
Area D Platoon Activation
When a mutual aid request is made from a local police department for their Area, the request goes through the Area D DMAC Diana Manzano-Garcia by calling 24/7 mobile number 626-201-0919. Example: Claremont PD has a major disturbance at a night club that escalates into a riot in their downtown area. Their request for Area D Platoon Activaton to handle the situation would consist of a notification to the Area D DMAC. Area D CS will, in turn, contact the lead agency LEC, and begin calling other agencies withing Area D.
Mutual aid is a request from an Area for 50% of a police department’s uniformed field force for a major event/incident such as civil unrest, large fire, earthquake, or other type incidents that have overwhelmed the local law enforcement’s ability to respond effectively to the incident.
Assistance is an immediate request for help by a mutual aid law enforcement agency such as Monterey Park PD requesting three units to help with a barricaded suspect situation.
The following procedures are to be implemented when a mutual aid law enforcement agency from Area “D” requests mutual aid, not assistance.
