FEMA's countywide study for Leon County has 86 FIRM panels, the newest effective August 2009; 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 Leon house comes from a licensed surveyor and is often on file with the county or city building office (Building Plans Review 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 Leon lot shows the same lines the property appraiser draws. Leon County covers about 427,794 acres of land and 21,354 acres of water.
Mapped lines are approximate. The Leon County Property Appraiser keeps the parcel record; a licensed surveyor sets the true corners.
