Maps of Floodplains
Maps of Floodplains
Floodplain maps provide the basis for floodplain management, regulation, and insurance requirements by identifying flood-prone areas that may threaten life and property. Floodplain maps are reviewed and approved by FEMA. Once approved, the floodplain maps guide flood management programs, including floodplain regulation, safety, preservation, preparation and mitigation.
Use the interactive Map of Floodplains (Interactive) to see if your property is in a floodplain.
