The Flood Insurance Rate Maps (FIRM) provide a basis for determining if a property is within a floodplain. On December 20, 2000, the Federal Emergency Management Agency (FEMA) adopted the latest flood insurance rate maps for Polk County. Copies of the FIRM panels are available from FEMA, at 800-358-9616 or the Map Service Center. The flood maps are also available at area libraries, the East Polk Board of Realtors and the Polk County Builders Association.
