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 Gilmer County has 53 FIRM panels, the newest effective June 2009; 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 Gilmer 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 West Virginia statewide parcel layer (WV GIS Technical Center, from each county assessor), so a Gilmer lot shows the same lines the county assessor draws. Gilmer County covers about 216,642 acres of land and 1,009 acres of water.
Mapped lines are approximate. The Gilmer County assessor keeps the parcel record (Gilmer County website); a licensed surveyor sets the true corners.
Zoning
Gilmer County zones its unincorporated land, and Glenville zones the land inside its limits. ParcelSheet shows the use the county assessor lists for the lot and links the county planning commission for the district, the uses it allows and the lot size it needs.
ADU and guest houses
Under West Virginia's land use law (W. Va. Code chapter 8A), local governments can allow an accessory dwelling unit on a lot with a house. Whether a Gilmer lot can add one depends on its district; the county planning commission 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. Gilmer County is soil survey area WV021, Gilmer County, West Virginia, last updated August 2026, on Web Soil Survey.
