The Association of State Floodplain Managers continues to use the cost estimates from this report to promote increased funding for flood hazard mapping. Completed in 2013, this internally-funded project developed an estimate of the total cost to complete floodplain mapping of the country based on parameters specified in the Biggert-Waters Flood Insurance Reform Act of 2012, and ASFPM’s projection of what constitutes adequate flood mapping for the country. This estimate shows the initial cost to complete flood mapping for the nation ranges from $4.5 billion to $7.5 billion. These cost estimates are repeatedly being cited by Congress justifying the need for increased funding for flood hazard mapping.
