Weighing a property around Ismay? Checking the Miles City flood zone map reveals whether it sits in a FEMA flood zone, and no account is needed. What this Miles City guide covers: locating a parcel on FEMA's map, decoding A, AE and X, and pairing it with the Montana Cadastral.
Getting started with the Miles City flood zone map
Start with FEMA's Flood Map Service Center: type an address near Ismay, then open the map view for that panel. Rural land near Ismay with no street number can still be found: pan from the closest town and click the spot.
Getting to the right map
Go first to the Montana Cadastral; it covers every assessed parcel around Kinsey and Ismay. For a parcel near Kinsey, enter a street address, an owner's name or a parcel number, then pick the result to center the map on it. For a home near Kinsey, the parcel card typically gives the owner of record, acreage on the tax roll, a parcel ID and often a sale date.
Deeds, plats and who keeps them
The map is an index, not the title: recorded deeds, plats and easements covering ground around Ismay sit with the County Clerk and Recorder. Inherited tracts near Kinsey may go back through a long string of deeds, and a title company can sort it out on a real sale.
Water near Kinsey
Low-lying fields near Ismay may not have detailed mapping, so ask neighbors about past flooding. Wetlands near Kinsey can limit building even outside a flood zone; the National Wetlands Inventory mapper shows mapped wetlands.
Sections, lots and bearings
Montana is laid out under the Public Land Survey System, so deeds around Ismay 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 Kinsey odd-sized. Keep the legal description for land near Ismay for any title or survey request.
Questions to ask before you buy
Ask the listing agent for any Elevation Certificate for the house near Ismay; getting a quote early avoids surprises.
Using it on a phone
Most viewers work in a phone browser, which helps when you're standing on land near Kinsey, but coverage can be spotty out of town. A screenshot of the parcel near Kinsey with its ID keeps working without signal.
Miles City and the county around it
Miles City sits in Custer County, Montana, which means parcel data comes from the county. Miles City is also the county seat, handy when you need recorded documents. For a tract near Kinsey, City or town hall handles things like zoning, permits and utilities for lots inside the boundary, while the county keeps the tax map. Lots just outside the town limits out by Ismay usually answers to county rules rather than the town's.
Reading A, AE and X
An AE label includes a base flood elevation (BFE), which plain A zones lack; that elevation drives building rules near Kinsey. For a home near Ismay, minimal risk is not no risk: according to FEMA, floods happen outside mapped zones too.
Parcel lines plus flood zones
FEMA doesn't draw property lines, so pair it with the Montana Cadastral for the outline of the tract near Ismay.
Next door to Custer County
Custer County borders Carter County, Fallon County, Garfield County, Powder River County, and Prairie County, and each of those keeps its own parcel map. Ground near Kinsey that runs to the line may be split in two county records, so open the neighboring map as well. Our state page links every neighboring county map for Montana.
Getting your bearings
Miles City serves as the county seat, home to the main records offices. Smaller places on the map include Ismay and Kinsey, where town lots give way to larger tracts. About 11,985 people call Custer County home (Census Bureau estimate, 2023) spread over about 3,783 square miles. Custer County was formed in 1865, and some chains of title near Ismay are long.
Money questions tied to the zone
Closer to Ismay, ask for an Elevation Certificate: it compares the building to the BFE. Remodeling a house in a zone near Kinsey usually means extra permit review; call the permitting office early.
Before you lean on the lines
Listed acreage is a tax-roll number; only a licensed surveyor sets the real boundary on land around Kinsey. Records update in batches, so a recent sale near Ismay might lag behind.
Questions about the Miles City flood zone map
Is flood insurance mandatory near Kinsey?
Good question; for a building near Ismay in an A or V zone with a federally backed or regulated mortgage, it's generally required; elsewhere it's optional.
How often are flood maps updated around Ismay?
Good question; a new study can move a zone line near Ismay; your community is notified before changes take effect.
Do I need to worry about flooding in Zone X for land near Ismay?
For most people, Zone X near Ismay means moderate (shaded) or minimal (unshaded) mapped risk, and floods still happen outside high-risk zones.
Is AE a high-risk flood zone near Kinsey?
It depends, but an AE zone has a 1% annual chance of flooding and a base flood elevation, so builders near Ismay design to that elevation.
What's a legal description for land near Kinsey?
If the land is near Ismay, deeds use lot and block, metes and bounds or survey descriptions, and the parcel record often summarizes it.
