What is a flood map?
Flood maps show a community’s risk of flooding. Specifically, flood maps show a community’s flood zone, floodplain boundaries, and base flood elevation.
Property owners, insurance agents, and lenders can use flood maps to determine flood insurance requirements and policy costs.
Because your flood risk changes over time, the National Flood Insurance Program (NFIP) and the Federal Emergency Management Agency (FEMA) work with communities across the country to identify and map flood risk on an ongoing basis.
