  "description": "The flood zones of FEMA's National Flood Hazard Layer for the United States, assembled from the county-by-county shapefile deliveries into GeoParquet 2.0 with a bbox covering, one file per delivery, checked against FEMA's list every day (last: 2026-10-03): a delivery FEMA republishes replaces its file. Public domain, FEMA. Not a FEMA product and not the effective Flood Insurance Rate Map: do not use it for flood zone determinations, insurance rating, regulatory or legal purposes; use the FEMA Flood Map Service Center for those. FEMA has not reviewed, approved or endorsed this redistribution.",
