Fire District Batallion Territory

A polygon feature class of Miami-Dade County Fire Rescue (MDFR) Fire District Battalion Territories. The territories represent MDFR fire battalion jurisdiction or responsibility. Therefore, the five municipalities that have their own fire departments - Miami, Miami Beach, Coral Gables, Hialeah, and Key Biscayne - are excluded from the MDFR territories with the exception of the Port of Miami (station 39) which is in the City of Miami and the northeastern corner of Fisher Island (station 42) which is inside Miami Beach. Large areas of water and uninhabited islands, such as those of the Atlantic Ocean and Biscayne Bay, are also excluded from the MDFR territories, although this exclusion is currently considered inconsistent with the true definition of territory (meaning, jurisdiction/responsibility), since the MDFR Fire Boat at station 39 and many stations with rigid-hull inflatable boats (RHIBs) can and do respond in these unincorporated areas of water. FireDistrictBattalionTerritory is created and updated by performing a dissolve on the FireStationDistrictTerritory feature class. Each time FireDistrictStationTerritory is updated, FireDistrictBattalionTerritory must also be updated.
