Weighing a property around Broadus? The Powder River County flood zone map tells you whether FEMA puts it in a high-risk zone, and it costs nothing to check. This Powder River County guide covers: locating a parcel on FEMA's map, reading the zone codes, and pairing it with the Montana Cadastral.
Getting started with the Powder River County flood zone map
For a more interactive look, use the National Flood Hazard Layer viewer, which draws the zones over aerial imagery, and that holds around Custer National Forest too. Rural land near Coalwood with no street number can still be found: pan from the closest town and click inside the land.
Getting to the right map
For property near Coalwood, the public parcel map for this area is the Montana Cadastral, and it opens in a browser with no account. With a lot near Custer National Forest, type a street address, an owner's name or a parcel number, and the viewer zooms to the match. With a lot near Coalwood, save the parcel ID from that panel; every office in the county uses it to find the file.
How land is described here
Montana follows the Public Land Survey System, so deeds around Coalwood reference sections and townships. Each section is nominally a mile square, about 640 acres, and a township holds 36 of them, though corrections make some sections near Elkhorn Crossing odd-sized. Copy the legal description from the record for the parcel near Broadus when you talk to a surveyor.
What the zone letters mean
For a parcel near Belle Creek, A and V zones are Special Flood Hazard Areas, which FEMA defines as a 1% annual chance of flooding. If the land is near Broadus, shaded Zone X is moderate risk, roughly the 100- to 500-year range; plain X, or C on older maps, means minimal mapped risk.
Land on the county line
Powder River County meets Big Horn County, Carter County, Custer County, Rosebud County, and Campbell County, WY; every one of them runs a separate parcel map. Acreage along the edge near Coalwood may show up across two assessors' files, so check the adjacent map too. If the land is near Elkhorn Crossing, our state page lists each bordering county map across Montana.
A quick look at the area
Broadus holds the county offices, home to the main records offices. You'll also find Biddle, Belle Creek, Coalwood, and Elkhorn Crossing, each with its own cluster of lots. About 1,743 people call Powder River County home (Census Bureau estimate, 2023) spread over about 3,298 square miles. Powder River County was formed in 1919, so old deeds can run back a long way. Landmarks such as Custer National Forest are easy to spot when you zoom out.
Backing up the map with records
For property near Elkhorn Crossing, the map is an index, not the title: recorded deeds, subdivision plats and easements for parcels in the county sit with the County Clerk and Recorder. Older tracts around Broadus may trace back through several deeds, and a title company is worth hiring on a real sale.
Use the county map alongside FEMA
FEMA doesn't draw property lines, so check the Montana Cadastral too to see exactly which lot near Custer National Forest you're looking at.
Field tips
The parcel map usually runs in a mobile browser, useful out on a road near Coalwood, though signal can drop in rural spots. A screenshot of the parcel near Elkhorn Crossing with its ID is a good backup.
Questions to ask before you buy
For a home near Broadus, request about past flood claims before closing; an insurance quote early avoids surprises.
What a flood zone means for a buyer
For a tract near Biddle, an Elevation Certificate from a surveyor helps: it can change the insurance price a lot. New construction in a floodplain near Elkhorn Crossing can trigger elevation rules; ask the local floodplain administrator early.
Water near Broadus
Small streams around Elkhorn Crossing aren't always studied in detail, so walk the land after rain. Wet ground around Epsie is a separate issue from flood zones; check the National Wetlands Inventory mapper for a first look.
Limits of the parcel data
For land near Broadus, acreage on the record is an estimate; only a licensed surveyor sets the real lines on the ground. In and around Biddle, owner names and values update on a schedule, so a deed recorded last month may not show yet.
