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 DFIRM Database presents the flood risk information depicted on the FIRM in a digital format suitable
for use in electronic mapping applications. The DFIRM database is a subset of the Digital FIS database that
serves to archive the information collected during the FIS. |

<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN><SPAN>The Digital Flood Insurance Rate Map (DFIRM) Database depicts flood risk information and supporting data used to develop the risk data. The primary risk classifications used are the 1-percent-annual-chance flood event, the 0.2-percent-annual-chance flood event, and areas of minimal flood risk. The DFIRM Database is derived from Flood Insurance Studies (FISs), previously published Flood Insurance Rate Maps (FIRMs), flood hazard analyses performed in support of the FISs and FIRMs, and new mapping data, where available. The FISs and FIRMs are published by the Federal Emergency Management Agency (FEMA). The file is georeferenced to earth's surface using the UTM projection and coordinate system. The specifications for the horizontal control of DFIRM data files are consistent with those required for mapping at a scale of 1:12,000</SPAN></SPAN></P><P><SPAN /></P></DIV></DIV></DIV> |

<DIV STYLE="text-align:Left;"><P STYLE="font-size:16ptmargin:7 0 7 0;"><SPAN><SPAN>The hardcopy FIRM and DFIRM and the accompanying FISs are the official designation of SFHAs and Base Flood Elevations (BFEs) for the NFIP. For the purposes of the NFIP, changes to the flood risk information published by FEMA may only be performed by FEMA and through the mechanisms established in the NFIP regulations (44 CFR Parts 59-78). These digital data are produced in conjunction with the hardcopy FIRMs and generally matches the hardcopy map exactly. However the hardcopy flood maps and flood profiles are the authoritative documents for the NFIP. Acknowledgement of FEMA would be appreciated in products derived from these data.</SPAN></SPAN></P><DIV><P><SPAN /></P></DIV></DIV> |
