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 Bowman County has 95 FIRM panels, the newest effective April 2016; 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 Bowman 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 North Dakota GIS Hub parcel layer (from each county), so a Bowman lot shows the same lines the county director of tax equalization draws. Bowman County covers about 743,558 acres of land and 3,357 acres of water.
Mapped lines are approximate. The Bowman County director of tax equalization keeps the parcel record (Bowman County website); a licensed surveyor sets the true corners.

Code chapters 11-33 for counties and 40-47 for cities), the county, the township or the city, depending on where the lot is can allow an accessory dwelling unit on a lot with a house. Whether a Bowman lot can add one depends on its district; the county, township or city zoning office has the rule. ParcelSheet shows the mapped lot size and the ground's slope, the first two things the question turns on.
Septic and soil
