Towns in Beckham County: Elk City, Sayre, Erick.
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 59 FIRM panels covering Beckham County, the newest effective May 2021; 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 Beckham 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 Oklahoma county parcel layers (each county publishes its own), so a Beckham lot shows the same lines the county assessor draws. Beckham County covers about 577,072 acres of land and 1,364 acres of water.
Mapped lines are approximate. The Beckham County assessor keeps the parcel record (Beckham County website); a licensed surveyor sets the true corners.
Zoning

ParcelSheet shows the use the county assessor lists for the lot and links the county planning commission or the city planning office for the district, the uses it allows and the lot size it needs.
ADU and guest houses
Under Oklahoma's county planning and zoning laws (Oklahoma Statutes Title 19, sections 865.51 and following), local governments can allow an accessory dwelling unit on a lot with a house. Whether a Beckham lot can add one depends on its district; the county planning commission or the city planning office has the rule. ParcelSheet shows the mapped lot size and the ground's slope, the first two things the question turns on.
