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 Lauderdale County has 54 FIRM panels, the newest effective September 2007; 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 Lauderdale 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 Tennessee Comptroller property boundaries layer (from each county assessor of property), so a Lauderdale lot shows the same lines the assessor of property draws. Lauderdale County covers about 302,013 acres of land and 19,831 acres of water.
