NFHL / FEMA public data
Enter a U.S. street address to find its FEMA flood zone designation, pulled live from the National Flood Hazard Layer.
Privacy: Addresses you enter are sent to Esri, OpenStreetMap and FEMA to find your flood zone. We don't store them.
Geocoding via the Esri World Geocoder, with OpenStreetMap Nominatim as a fallback. Flood zone data via FEMA's National Flood Hazard Layer (hazards.fema.gov). This is a convenience lookup, not an official determination — for insurance or permitting purposes, confirm with FEMA's Map Service Center or a licensed surveyor.
