Biennial Report Regulations
Every two years FEMA collects data from communities participating in the NFIP through the Biennial Report process. This provides communities an opportunity to identify floodplain mapping needs and request assistance in implementing a floodplain management program. The Biennial Report provides FEMA information on a community’s floodplain management program and changes in its flood hazard areas, which assists FEMA to evaluate the effectiveness of a community’s floodplain management activities. The Biennial Report shows FEMA nationwide trends and patterns, which FEMA uses to help guide improvements to the NFIP.
