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 Sarasota County has 151 FIRM panels, the newest effective March 2024; coastal V zones, where waves add to the flood, are mapped along its shore.
The official panel and any Letter of Map Amendment are at FEMA's Map Service Center. An elevation certificate for a Sarasota house comes from a licensed surveyor and is often on file with the county or city building office (Building).
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 Sarasota lot shows the same lines the property appraiser draws. Sarasota County covers about 355,899 acres of land and 268,454 acres of water.
Mapped lines are approximate. The Sarasota County Property Appraiser keeps the parcel record; a licensed surveyor sets the true corners.
