Ahead of any purchase around Myers, look at the Treasure County flood zone map: FEMA's zone label affects insurance, building rules and resale. What this county guide covers: the free FEMA tools, what each zone label means, lender insurance rules and what a LOMA is, at least around Sanders.
Checking the Treasure County flood zone map step by step
Flood zones come from FEMA's Flood Map Service Center: type an address near Interstate 94, then open the map view for that panel. Vacant ground around Hysham can still be found: zoom in from Interstate 94 then click the parcel area.
Getting to the right map
Go first to the Montana Cadastral; it maps every tax parcel around Hysham and Interstate 94. If you only know roughly where the land is, zoom in from Interstate 94 until the lines appear, then click inside the one you want. If the land is near Hysham, save the parcel ID before closing the panel; every records desk in the county asks for it first.
Low spots and local drainage
Creeks and ditches near Interstate 94 may not have detailed mapping, so walk the land after rain. Wet ground around Interstate 94 is a separate issue from flood zones; check the National Wetlands Inventory mapper for a first look.
Zones on the Treasure County flood zone map
With a lot near Sanders, A and V zones are Special Flood Hazard Areas, meaning a 1% or greater chance of flooding each year. If you're looking near Sanders, minimal risk is not no risk: according to FEMA, floods happen outside mapped zones too.
Next door to Treasure County
Treasure County borders Big Horn County, Rosebud County, and Yellowstone County, and each of those keeps its own parcel map. Acreage along the edge near Interstate 94 may be split in two county records, so open the neighboring map before you assume the acreage. For a parcel near Interstate 94, the Platbookmapper state page links every bordering county map for Montana.
Backing up the map with records
Before you sign anything, pull the recorded deed through the County Clerk and Recorder; the parcel line is a drawing of it, which applies near Interstate 94 as much as anywhere. For acreage around Sanders, have ready the document number from the tax record to skip a name search.
Limits of the parcel data
Parcel lines are drawn for taxes, not measured on the ground, so a fence near Interstate 94 often sits some distance off the line on screen. Owner names and values update on a schedule, so a recent sale near Interstate 94 might lag behind.
Matching the zone to the lot lines
Where a floodplain cuts across acreage near Interstate 94, the location of the house or building pad decides a lot.
Using it on a phone
The parcel map usually runs in a mobile browser, which helps when you're standing on land near Interstate 94, but coverage can be spotty out of town. A saved image of the lot near Interstate 94 and its lines keeps working without signal.
What to request from a seller
Ask the listing agent for any Elevation Certificate on the property near Interstate 94; an insurance quote early keeps the budget honest.
Treasure County in a few facts
Hysham serves as the county seat, which is where the courthouse records live. You'll also find Myers, Sanders, and Interstate 94, where town lots give way to larger tracts. Roughly 772 people live in this county (Census Bureau estimate, 2023) spread over about 978 square miles around Hysham. Treasure County was organized in 1919, which matters when you trace an old farm's title.
Sections, lots and bearings
Montana uses the Public Land Survey System, so rural legal descriptions near Interstate 94 cite section, township and range. A standard section is about one square mile, roughly 640 acres, and a township holds 36 of them, though corrections make some sections near Sanders odd-sized. Keep the legal description for land near Interstate 94 for any title or survey request.
Lenders and permits
With a lot near Interstate 94, ask for an Elevation Certificate: it compares the building to the BFE. New construction in a floodplain near Interstate 94 can trigger elevation rules; check with the county or town building office early.
Which office to call
Questions about value or the owner field for land near Interstate 94 belong with the Montana Department of Revenue, since that office keeps the assessment data. Questions about what you can build around Hysham need the planning or permitting office, town or county, depending on location.
