Types of Flood Map Indexes

The Index shows the outline of the mapped community and the numbers and positions of the individual Map Panels. There are three different types of Indexes depending upon the map format used for the community you are interested in:

  • Flood Hazard Boundary Map (FHBM) Index
  • Flood Insurance Rate Map (FIRM) Index or Flood Boundary and Floodway Map (FBFM) Index
  • Countywide Flood Insurance Rate Map (FIRM) Index
