  • What is a DFIRM?

    The DFIRM Database is a digital version of the FEMA flood insurance rate map that is designed for use with digital mapping and analysis software.

    The DFIRM is designed to provide the user with the ability to determine the flood zone, base flood elevation and the floodway status for a particular location. It also has NFIP community information, map panel information, cross section and hydraulic structure information, and base map information like road, stream, and public land survey data.
