Towns in Gooding County: Gooding, Wendell.
Flood zone by address
ParcelSheet reads FEMA's National Flood Hazard Layer at the lot: the zone, whether it is a high risk area where lenders ask for flood insurance, and the base flood elevation where FEMA lists one. FEMA has 1 FIRM panels covering Gooding County, the newest effective September 2008; no coastal V zones are mapped in it.
The official panel and any Letter of Map Amendment are at FEMA's Map Service Center. An elevation certificate for a Gooding house comes from a licensed surveyor and is often on file with the county or city building office.
Property lines
The parcel outline, parcel number and mapped size come from the State of Idaho public parcels, from counties that share them, so a Gooding lot shows the same lines the county assessor draws. Gooding County covers about 466,767 acres of land and 3,081 acres of water.
Mapped lines are approximate. The Gooding County assessor keeps the parcel record (Gooding County website); a licensed surveyor sets the true corners.
Zoning
Gooding County zones its unincorporated land, and Gooding, Wendell each zone the land inside their limits. ParcelSheet shows the use the county assessor lists for the lot and links the county planning and zoning office for the district, the uses it allows and the lot size it needs.
ADU and guest houses
Under Idaho's Local Land Use Planning Act (Idaho Code Title 67, Chapter 65), local governments can allow an accessory dwelling unit on a lot with a house. Whether a Gooding lot can add one depends on its district; the county planning and zoning office has the rule. ParcelSheet shows the mapped lot size and the ground's slope, the first two things the question turns on.
Septic and soil
ParcelSheet reads the USDA soil survey at the lot: the soil's name, its septic absorption rating and whether it is prime farmland.
