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 Lea County has 100 FIRM panels, the newest effective December 2008; 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 Lea house comes from a licensed surveyor and is often on file with the county or city building office.
Property lines
The parcel outline, parcel number and mapped size come from the New Mexico county parcel layers (each county publishes its own), so a Lea lot shows the same lines the county assessor draws. Lea County covers about 2,810,593 acres of land and 2,013 acres of water.
Mapped lines are approximate. The Lea County assessor keeps the parcel record (Lea County website); a licensed surveyor sets the true corners.
