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 has 40 FIRM panels covering Rapides Parish, the newest effective February 2023; 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 Rapides house comes from a licensed surveyor and is often on file with the parish or city building office.
Property lines
