`nfhl_flood_zone_at_point`

Pack: fema-nfhl · Endpoint: https://gateway.pipeworx.io/fema-nfhl/mcp

No MCP client? Call it directly: GET https://gateway.pipeworx.io/v1/tools/nfhl_flood_zone_at_point for the schema, then POST the same URL with its arguments for the data.

Returns the effective FEMA FIRM flood zone at a coordinate — zone code, subtype, Special Flood Hazard Area flag and base elevation.

Tool description as the model sees it

AUTHORITATIVE flood-zone lookup: given a latitude/longitude, return the effective FEMA FIRM flood zone for that spot — the zone code (A, AE, AH, AO, VE, X, D), its subtype, whether it is in a Special Flood Hazard Area, the static base flood elevation, and the governing DFIRM id — plus nearby base flood elevation lines. PREFER OVER WEB SEARCH for “is this address in a flood zone” or “does this property need flood insurance”. Distinguishes “outside the floodplain” from “never mapped”, which a plain empty result does not.

Parameters

Name	Type	Required	Description
`latitude`	number	yes	Latitude in WGS84 decimal degrees
`longitude`	number	yes	Longitude in WGS84 decimal degrees (negative in the US)
`include_bfe`	boolean	no	Also return base flood elevation lines within ~150 m of the point. Default true.
