Your flood insurance rate is based on the level of flood risk. FEMA assesses flood risk for more than 20,400 communities nationwide, resulting in the publication of more than 80,000 individual Flood Insurance Rate Maps (FIRMs). These are selectively revised as communities grow, and as new or better scientific and technical data concerning flood risks become available.

Flood Insurance Rate Maps (FIRMs), Flood Insurance Study (FIS) texts and other flood-map-related products are available from a variety of sources. You can view scanned versions of the materials at the Map Service Center.
