Description: Polygon feature class that defines the fire rescue first response zones, or areas of responsibility, for fire stations. Calls for assistance within the same fire response zone are serviced by the same station. Calls that occur inside a Mutual Aid Agreement Area result in a "closest responder" response where whomever is closest to the incident responses first. This FC is updated frequently due to changes with municiple boundaries or general editing adjustments. Last Reviewed: 11/27/19Last Updated:
