{"jsonrpc":"2.0","id":1,"method":"tools/list"}nfhl_flood_zone_at_point — 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.nfhl_query — Query any layer of the FEMA National Flood Hazard Layer with an ArcGIS WHERE clause and optional bounding box — flood hazard zones, base flood elevations, floodways, LOMRs and LOMAs, FIRM panels with their effective dates, levees, cross-sections, political jurisdictions. Use for area questions ("every floodway polygon in this county", "LOMRs issued on this DFIRM"). Layer ids come from nfhl_layers.nfhl_layers — List every layer in the FEMA National Flood Hazard Layer MapServer with its id, name and geometry type, plus a plain-English guide to the layers that matter (flood hazard zones, base flood elevations, LOMRs, LOMAs, FIRM panels, levees, NFHL availability). Call this before nfhl_query.Code samples (curl / TypeScript / one-click client install), schemas, and the live playground are on the pack page:
