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 Monongalia County has 32 FIRM panels, the newest effective April 2019; 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 Monongalia 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 Monongalia lot shows the same lines the county assessor draws. Monongalia County covers about 230,460 acres of land and 3,703 acres of water.
Mapped lines are approximate. The Monongalia County assessor keeps the parcel record (Monongalia County website); a licensed surveyor sets the true corners.
Zoning
Monongalia County zones its unincorporated land, and Morgantown 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.

ParcelSheet shows the mapped lot size and the ground's slope, the first two things the question turns on.
Septic and soil
