The National Flood Hazard Layer (NFHL) data incorporates all Digital Flood Insurance Rate
Map(DFIRM) databases published by FEMA, and any Letters Of Map Revision (LOMRs) that have been
issued against those databases since their publication date. The DFIRM Database is the digital,
geospatial version of the flood hazard information shown on the published paper Flood Insurance Rate
Maps(FIRMs). 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 NFHL data are 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
specifications for the horizontal control of DFIRM data are consistent with those required for
mapping at a scale of 1:12,000. The NFHL data contain layers in the Standard DFIRM datasets except
for S_Label_Pt and S_Label_Ld. The NFHL is available as State or US Territory data sets. Each State
or Territory data set consists of all DFIRMs and corresponding LOMRs available on the publication
date of the data set.
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" (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 NFHL data present the flood risk information depicted on the FIRM in a digital format
suitable for use in electronic mapping applications. The NFHL database is a subset of the
information created for the FIS and serves as a means to archive a portion of the information
collected during the FIS.

When FEMA revises an FIS, adjacent studies are checked to ensure agreement between flood
elevations at the boundaries. Likewise flood elevations at the confluence of streams studied
independently are checked to ensure agreement at the confluence. The FIRM and the FIS are developed
together and care is taken to ensure that the elevations and other features shown on the flood
profiles in the FIS agree with the information shown on the FIRM. However, the elevations as shown
on the FIRM are rounded whole-foot elevations. They must be shown so that a profile recreated from
the elevations on the FIRM will match the FIS profiles within one half of one foot.
The individual components of the National Flood Hazard Layer data are compiled in
conjunction with the hardcopy FIRM and the final FIS report. The specifics of the hydrologic and
hydraulic analyses performed are detailed in the FIS reports available for each community. The
results of these studies are submitted in digital format to FEMA. These data and unrevised data from
effective FIRMs are compiled onto the base map used for DFIRM publication and checked for accuracy
and compliance with FEMA standards. As new DFIRM data sets are received the individual DFIRM layers
are sewn into the nationwide layers of the NFHL. LOMRs for the DFIRMs in the NFHL are cut directly
into the NFHL data layers as they are being produced and finalized.
