Flood Insurance Rate Maps (FIRM)

What is a Flood Insurance Rate Map (FIRM) & How Do I Use It?

A FIRM is a map created by the NFIP for floodplain management and insurance purposes. Digital versions of these maps are called DFIRMs.

A FIRM will generally show a community's base flood elevations, flood zones, and floodplain boundaries. As a property owner/renter, you can use this map to get a reliable indication of what flood zone you're in. However, maps are constantly being updated due to changes in geography, construction and mitigation activities, and meteorological events. Therefore, for a truly accurate determination, contact your insurance agent or company, or your community floodplain manager.
