Flood zone by address

FEMA's countywide study for Holmes County has 44 FIRM panels, the newest effective December 2010; 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 Holmes house comes from a licensed surveyor and is often on file with the county or city building office (Building, Planning, & Zoning).
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 Holmes lot shows the same lines the property appraiser draws. Holmes County covers about 306,469 acres of land and 6,521 acres of water.
Mapped lines are approximate. The Holmes County Property Appraiser keeps the parcel record; a licensed surveyor sets the true corners.
