flood_storm_information
Federal flood mapping for the property: zone classification, insurance requirement, community and panel identifiers, and evacuation designation.
FEMA flood and storm information data containing flood zone classifications, insurance requirements, and evacuation zone designations for property locations.
The question it answers
What is this house, physically?
The feature vector, taken from the source of record rather than from a listing agent. Assessor and parcel records are authoritative; listing fields are agent-entered, inconsistent between markets, and absent entirely for a property that was never listed.
Why it matters
Flood zone determines whether insurance is mandatory, which is a monthly cost and, in some markets, a financeability question rather than a preference. Evacuation designation is a separate and locally-defined overlay that does not follow the flood map.
In practice
The panel and version identifiers are carried alongside the zone because maps are revised, and a determination is only as good as the panel it was read from. A zone without the panel it came from cannot be re-checked.

Provenance and coverage
A record of this class is validated against the same definition whatever jurisdiction it came from, which is what makes two counties comparable without a per-county adapter. A jurisdiction appears below only where a committed configuration serves this class's surface.
