FEMA's countywide study for Washington County has 37 FIRM panels, the newest effective July 2011; 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 Washington house comes from a licensed surveyor and is often on file with the county or city building office (Building and Permits).
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 Washington lot shows the same lines the property appraiser draws. Washington County covers about 374,193 acres of land and 20,017 acres of water.
Mapped lines are approximate. The Washington County Property Appraiser keeps the parcel record; a licensed surveyor sets the true corners.
