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 Polk County has 124 FIRM panels, the newest effective December 2016; 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 Polk house comes from a licensed surveyor and is often on file with the county or city building office (Building Permits, Contractor Licenses and Inspections).
Property lines
The parcel outline, parcel number and mapped size come from the Florida statewide cadastral (county property appraiser parcels with the Department of Revenue tax roll), so a Polk lot shows the same lines the property appraiser draws. Polk County covers about 1,151,220 acres of land and 135,627 acres of water.
Mapped lines are approximate. The Polk County Property Appraiser keeps the parcel record; a licensed surveyor sets the true corners.
