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 Wetzel County has 36 FIRM panels, the newest effective September 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 Wetzel 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 Wetzel lot shows the same lines the county assessor draws. Wetzel County covers about 229,166 acres of land and 2,085 acres of water.
