Floodplain mapping is a sound investment that saves lives, reduces flood losses, and keeps communities thriving, all at a 2-to-1 cost benefit for taxpayers.
In its Flood Mapping for the Nation report, ASFPM estimates the cost to complete flood mapping in the US at $3.2 billion to $11.8 billion. The steady-state cost to then maintain accurate and up-to-date flood maps ranges from $107 million to $480 million annually.
Floods are the leading cause of natural disaster losses in the US, and more than half of American voters are personally impacted by flooding. Without complete or accurate flood maps, local officials face serious difficulties in guiding development away from the most hazardous areas or ensuring that development is properly built to protect lives and property.
