FloodHazardZones
The FIRM is the basis for floodplain management, mitigation, and insurance activities for the National Flood Insurance Program (NFIP). Insurance applications include enforcement of the mandatory purchase requirement of the Flood Disaster Protection Act, which "... requires the purchase of flood insurance by property owners who are being assisted by Federal programs or by Federally supervised, regulated or insured agencies or institutions in the acquisition or improvement of land facilities located or to be located in identified areas having special flood hazards, " Section 2 (b) (4) of the Flood Disaster Protection Act of 1973. In addition to the identification of Special Flood Hazard Areas (SFHAs), the risk zones shown on the FIRMs are the basis for the establishment of premium rates for flood coverage offered through the NFIP. The FIRM Database presents the flood risk information depicted on the FIRM in a digital format suitable for use in electronic mapping applications. The FIRM Database serves to archive the information collected during the Flood Risk Project. (from FEMA metadata)
The FEMA Flood Zones data shows areas that have a 1% annual chance of a flood event (100-year flood zone) and areas that have a 0.2% annual chance of a flood event (500-year flood zone).
FEMA calls flood zone data the Flood Insurance Rate Map (FIRM) database.
DFIRM is a digital version of FEMA's new updated Flood Insurance Rate Maps (FIRM). FEMA is engaged in a multi-year process to update all FIRMs in the US.
