Before an offer near Volborg, check the Custer County flood zone map: FEMA's zone label affects insurance, building rules and resale. What this Custer County guide covers: the free FEMA tools, what each zone label means, lender insurance rules and how to challenge a map that looks wrong.
Checking the Custer County flood zone map step by step
For parcel-by-parcel detail, try the National Flood Hazard Layer viewer, where zone shading sits over a photo base, which applies near Volborg as much as anywhere. Vacant ground around Volborg is still easy to locate: pan from the closest town and click the spot.
The viewer Custer County publishes
Begin with the Montana Cadastral; it covers each assessed parcel from Volborg to Miles City. Closer to Kinsey, put in a street address, an owner's name or a parcel number, and the matching parcel lights up. If the land is near Volborg, copy the parcel ID before closing the panel; every office in the county asks for it first.
Zones on the Custer County flood zone map
With a lot near Volborg, any A or V zone mark the Special Flood Hazard Area, which FEMA defines as a 1% annual chance of flooding. On ground around Miles City, a low-risk label isn't a guarantee: FEMA notes that floods happen outside mapped zones too.
Low spots and local drainage
Creeks and ditches near Volborg aren't always studied in detail, so walk the land after rain. Marshy spots near Ismay can limit building too; the National Wetlands Inventory mapper shows mapped wetlands.
Before you lean on the lines
For acreage around Kinsey, acreage on the record is an assessed number; only a licensed surveyor establishes the real boundary on the ground. Out toward Volborg, owner names and values update on a schedule, so a deed recorded last month might lag behind.
Deeds, plats and who keeps them
The map is an index, not the title: deeds, plats and easements covering ground around Kinsey are filed with the County Clerk and Recorder. For a home near Volborg, bring the book and page shown in the record panel to skip a name search.
Questions to ask before you buy
If you're looking near Kinsey, ask the seller about past flood claims before closing; getting a quote early keeps the budget honest.
Which office to call
Questions about value or the owner field for land near Volborg are handled by the Montana Department of Revenue, which maintains the tax roll. Zoning, permits and septic questions near Ismay are for the local planning and health departments, and the answer depends on jurisdiction.
Lining it up with the parcel map
FEMA's map shows zones but not ownership, so pair it with the Montana Cadastral to confirm you have the right parcel near Ismay.
Places you'll see on the map
Miles City holds the county offices, where most land records are kept. You'll also find Ismay, Kinsey, and Volborg, each with its own cluster of lots. Around 11,985 people live in Custer County (Census estimate, 2023) on roughly 3,783 square miles. The county was organized in 1865, and some chains of title near Ismay are long.
Money questions tied to the zone
If you're looking near Volborg, an Elevation Certificate from a surveyor helps: it records the building's elevation against the base flood. Building or adding on near Kinsey in a mapped zone usually means extra permit review; check with the county or town building office early.
Legal descriptions in Montana
Montana uses the Public Land Survey System, which means a tract near Ismay is described by section, township and range. A standard section is about one square mile, roughly 640 acres, with 36 sections to a township, though real sections near Miles City vary in size. Copy the legal description from the record for the parcel near Miles City when you talk to a surveyor.
When a parcel crosses a boundary
Custer County meets Carter County, Fallon County, Garfield County, Powder River County, and Prairie County, all with their own assessor records. Ground near Volborg that runs to the line can show up in two county records, so check the neighboring map before you assume the acreage. For land near Ismay, the Platbookmapper state page lists each bordering county map for Montana.
