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 Marion County has 218 FIRM panels, the newest effective April 2017; 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 Marion house comes from a licensed surveyor and is often on file with the county or city building office (Building Codes, Inspections, Licensing 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 Marion lot shows the same lines the property appraiser draws. Marion County covers about 1,016,604 acres of land and 47,505 acres of water.
Mapped lines are approximate. The Marion County Property Appraiser keeps the parcel record; a licensed surveyor sets the true corners.
An example from the county's own records: parcel 22737-000-00 in Ocala, a lot with one house, about 7,405 square feet as mapped, the house built in 1958. Open it to see every card ParcelSheet draws for a Marion lot.
