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 Putnam County has 105 FIRM panels, the newest effective February 2012; 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 Putnam house comes from a licensed surveyor and is often on file with the county or city building office (Building, Permits 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 Putnam lot shows the same lines the property appraiser draws. Putnam County covers about 466,180 acres of land and 63,049 acres of water.
Mapped lines are approximate. The Putnam County Property Appraiser keeps the parcel record; a licensed surveyor sets the true corners.
An example from the county's own records: parcel 02-10-26-0000-0630-0013 in Palatka, a lot with one house, about 7,405 square feet as mapped, the house built in 1976. Open it to see every card ParcelSheet draws for a Putnam lot.

ADU and guest houses
Florida Statute 163.31771 lets local governments allow an accessory dwelling unit on a lot with a house. Whether a Putnam lot can add one depends on its district; Planning and Zoning has the rule.
