Quality The DFIRM Database consists of countywide vector files and associated
attributes produced in conjunction with the hard copy FEMA FIRM. The published
effective FIRM and DFIRM maps are issued as the official designation of the
SFHAs. As such they are adopted by local communities and form the basis for
administration of the NFIP. ... View entire text
Access Constraints None
Use Constraints 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 match 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.
