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.

The official panel and any Letter of Map Amendment are at FEMA's Map Service Center. An elevation certificate for a Carroll 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 Arkansas GIS Office, statewide parcels from county assessors (CAMA), so a Carroll lot shows the same lines the county assessor draws. Carroll County covers about 403,154 acres of land and 5,613 acres of water.
