payable

FEMA flood zone for an address. Perfect for: 'flood zone for an address', 'FEMA flood designation', 'is this property in a floodplain', 'is this address in a 100-year flood zone', 'flood risk lookup'. Returns the FEMA NFHL flood-zone designation, 0.2%-annual-chance and BFE/floodway flags at the geocoded point, with source provenance. National. Not a flood insurance quote or a safe/unsafe verdict.
