Weighing a property around Gorham? A quick look at the Billings County flood zone map shows whether FEMA puts it in a high-risk zone, and it costs nothing to check. Covered here for the county: the free FEMA tools, what each zone label means, lender insurance rules and what a LOMA is for land near Little Missouri National Grassland.
The Billings County flood zone map: start here
If you'd rather pan and zoom, use the National Flood Hazard Layer viewer, which draws the zones over aerial imagery, whether the land is near North Billings or elsewhere in the county. A tract near Little Missouri River without an address can still be found: pan from the closest town and click inside the land.
Opening the official parcel viewer
Your first stop is the Billings County parcel viewer; it maps each tax parcel from South Billings to Theodore Roosevelt National Park. For land near South Billings, type a street address, an owner's name or a parcel number, and the matching parcel lights up. For a tract near North Billings, the record panel typically gives the owner of record, assessed acreage, a parcel ID and sometimes recent sales.
Zones on the Billings County flood zone map
For a home near Medora, A and V zones are Special Flood Hazard Areas, meaning a 1% or greater chance of flooding each year. In and around Theodore Roosevelt National Park, a shaded X area marks moderate flood hazard, between the 1% and 0.2% annual chance floods; plain X, or C on older maps, means minimal mapped risk.
Matching the zone to the lot lines
FEMA's map shows zones but not ownership, so open the Billings County parcel viewer next to see exactly which lot near Fryburg you're looking at.
Field tips
The parcel map usually runs in a mobile browser, useful out on a road near Fryburg, but coverage can be spotty out of town. A screenshot of the parcel near Fryburg with its ID keeps working without signal.
Before you lean on the lines
In and around North Billings, listed acreage is an assessed number; just a licensed surveyor sets the real lines on the ground. Closer to Fryburg, records update in batches, so a deed recorded last month might lag behind.
Offices that can help
Deeds, mortgages and recorded plats for land near Gorham sit in the index kept by the County Recorder, usually searchable by name or document number. Questions about what you can build around Gorham are for the local planning and health departments, depending on whether the land is inside town limits.
What to request from a seller
Near Little Missouri River, ask the seller whether the home has flooded before closing; an insurance quote early avoids surprises.
Money questions tied to the zone
For a structure inside an A or V zone and the loan is federally backed or regulated, mandatory purchase rules apply in communities in the NFIP, whether the land is near Theodore Roosevelt National Park or elsewhere in the county. Remodeling a house in a zone near Medora usually means extra permit review; ask the local floodplain administrator early.
Low spots and local drainage
Small streams around Gorham aren't always studied in detail, so walk the land after rain. Wetlands near Theodore Roosevelt National Park can limit building even outside a flood zone; the National Wetlands Inventory mapper shows mapped wetlands.
Neighboring parcel maps
The county touches Dunn County, Golden Valley County, McKenzie County, Slope County, and Stark County, all with their own assessor records, at least around Little Missouri National Grassland. Ground near South Billings that runs to the line may be split across two assessors' files, so check the adjacent map before you assume the acreage. For a home near Fryburg, our state page lists every bordering county map across North Dakota.
