2013 – ASFPM Releases Its First Flood Mapping For The Nation Report

The objective of Flood Mapping for the Nation is to develop an overall estimate of the cost to adequately complete the mapping of flood hazards and communicate flood risk for all communities in the United States. According to the report, the US has invested $4.3 billion in flood mapping to date, and has enjoyed multiple benefits from that investment, including providing the basis for guiding development that saves over $1 billion/year in flood damages. ASFPM identified criteria of what constitutes adequate flood mapping for the country, and has produced an estimate showing the initial cost to provide flood mapping for the nation ranging from $4.5 billion to $7.5 billion. The steady-state cost to then maintain accurate and up-to-date flood maps ranges from $116 million to $275 million annually. The report is updated in 2020.
