Weighing a property around Bozeman? A quick look at the Belgrade flood zone map shows whether it sits in a FEMA flood zone, and it costs nothing to check. What this Belgrade guide covers: finding the address on FEMA's map, reading the zone codes, and pairing it with the Gallatin County parcel viewer.
The Belgrade flood zone map: start here
The official source is FEMA's Flood Map Service Center: search an address around Manhattan, and choose the dynamic map. Vacant ground around Manhattan can still be found: zoom in from the nearest road and click inside the land.
The free map to start with
Go first to the Gallatin County parcel viewer; it includes each assessed parcel from Three Forks to Bozeman. For a parcel near Bozeman, 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 Bozeman, a pop-up or side panel usually lists the owner of record, acreage on the tax roll, a parcel ID and sometimes recent sales.
A short flood checklist
Request for any Elevation Certificate for the house near Three Forks; an insurance quote early keeps the budget honest.
When a parcel crosses a boundary
Gallatin County touches Fremont County, ID, Broadwater County, Jefferson County, Madison County, and Meagher County; every one of them runs a separate parcel map. Ground near West Yellowstone that runs to the line can show up across two assessors' files, so look at the adjacent map as well. Near Bozeman, our state page links every neighboring county map across Montana.
Places you'll see on the map
Bozeman is the county seat, home to the main records offices. You'll also find Manhattan, Three Forks, and West Yellowstone, where town lots give way to larger tracts. Roughly 126,409 people call Gallatin County home (Census estimate, 2023) on some 2,605 square miles. Gallatin County dates to 1865, and some chains of title near Three Forks are long. Features like Yellowstone National Park help you orient on the aerial around Three Forks.
Low spots and local drainage
Low-lying fields near Bozeman may not have detailed mapping, so look for water marks and debris lines. Wet ground around Three Forks is a separate issue from flood zones; the National Wetlands Inventory mapper shows mapped wetlands.
City limits and county records
Belgrade is part of Gallatin County, Montana, which means parcel data comes from the county. If you're looking near West Yellowstone, the municipality handles things like zoning, permits and utilities for lots inside the boundary, and the county still keeps the parcel and deed records. Acreage past the city limits near Three Forks often answers to county rules rather than the town's.
Offices that can help
Recorded documents for a parcel near West Yellowstone are with the County Clerk and Recorder, often with an online index. Questions about what you can build around West Yellowstone go to planning, building or health offices, and the answer depends on jurisdiction.
Decoding the flood zone labels
An AE label carries a published BFE, while plain Zone A does not; surveyors near Three Forks use that number. Closer to West Yellowstone, a shaded X area is moderate risk, roughly the 100- to 500-year range; unshaded X is minimal risk.
Use the county map alongside FEMA
FEMA doesn't draw property lines, so check the Gallatin County parcel viewer too to confirm you have the right parcel near Manhattan.
A word on accuracy
Acreage on the record is a tax-roll number; only a licensed surveyor sets the real boundary on land around Bozeman. For a tract near Manhattan, owner names and values update on a schedule, so a deed recorded last month might lag behind.
Backing up the map with records
The map is an index, not the title: recorded deeds, subdivision plats and easements covering ground around Bozeman are filed with the County Clerk and Recorder. For property near Three Forks, bring the instrument number shown in the record panel so staff can find the deed fast.
Insurance, lenders and building
If a building sits in a Special Flood Hazard Area and a federally regulated lender is involved, mandatory purchase rules apply where the community participates in the National Flood Insurance Program, whether the land is near West Yellowstone or elsewhere in the county. Building or adding on near Bozeman in a mapped zone can trigger elevation rules; check with the county or town building office early.
