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 parishwide study for Evangeline Parish has 24 FIRM panels, the newest effective September 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 an Evangeline house comes from a licensed surveyor and is often on file with the parish or city building office.
Property lines
The parcel outline, parcel number and mapped size come from the Louisiana parish parcel layers (each parish publishes its own), so an Evangeline lot shows the same lines the parish assessor draws. Evangeline Parish covers about 423,956 acres of land and 11,036 acres of water.
Mapped lines are approximate. The Evangeline Parish assessor keeps the parcel record (Evangeline Parish website); a licensed surveyor sets the true corners.
