Towns in Perkins County: Grant.
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's countywide study for Perkins County has 32 FIRM panels, the newest effective September 2005; 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 Perkins 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 NebraskaMAP statewide parcel layer (from each county assessor), so a Perkins lot shows the same lines the county assessor draws. Perkins County covers about 565,320 acres of land and 702 acres of water.
Mapped lines are approximate. The Perkins County assessor keeps the parcel record (Perkins County website); a licensed surveyor sets the true corners.
Zoning
Perkins County zones its unincorporated land, and Grant zones the land inside its limits. ParcelSheet shows the use the county assessor lists for the lot and links the county zoning office for the district, the uses it allows and the lot size it needs.
ADU and guest houses
Under Nebraska's county zoning law (Neb. Rev. Stat. 23-114) and each city's zoning powers, local governments can allow an accessory dwelling unit on a lot with a house. Whether a Perkins lot can add one depends on its district; the county 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. Perkins County is soil survey area NE135, Perkins County, Nebraska, last updated September 2026, on Web Soil Survey.
