Before you buy or build near Mildred, check the Prairie County flood zone map: a mapped flood zone changes insurance, permits and resale. In this Prairie County guide: locating a parcel on FEMA's map, reading the zone codes, and pairing it with the Montana Cadastral.
Checking the Prairie County flood zone map step by step
If the land is near Mildred, flood zones come from FEMA's Flood Map Service Center: enter the street address, and choose the dynamic map. Rural land near Zero with no street number can still be found: pan from the closest town and click the spot.
Pulling up a parcel
Begin with the Montana Cadastral; it includes every assessed parcel in the county, Terry included. If you only know roughly where the land is, follow the nearest road on the aerial and select the outline, which applies near Zero as much as anywhere. If the land is near Mildred, a pop-up or side panel usually lists the owner of record, assessed acreage, a parcel ID and often a sale date.
Water near Mildred
Creeks and ditches near Saugus may not have detailed mapping, so look for water marks and debris lines. Marshy spots near Terry can limit building too; check the National Wetlands Inventory mapper for a first look.
The paper trail behind a parcel
For anything that matters, request the recorded deed through the County Clerk and Recorder; the parcel line is a drawing of it, which applies near Saugus as much as anywhere. Out toward Mildred, bring the document number from the tax record to skip a name search.
Getting your bearings
Terry is the county seat, which is where the courthouse records live. You'll also find Fallon, Mildred, Saugus, and Zero. About 1,112 people live in Prairie County (Census estimate, 2023) spread over roughly 1,737 square miles. Prairie County dates to 1915, so old deeds can run back a long way.
Decoding the flood zone labels
For a tract near Zero, A and V zones are Special Flood Hazard Areas, land with a 1-percent chance of flooding in any year. For a tract near Saugus, minimal risk is not no risk: FEMA notes that many claims come from moderate- and low-risk areas.
Reading the legal description
Montana follows the Public Land Survey System, which means a tract near Mildred is described by 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 Zero odd-sized. Copy the legal description from the record for the parcel near Mildred before you request a deed or survey.
Neighboring parcel maps
Prairie County touches Custer County, Dawson County, Fallon County, Garfield County, and McCone County, all with their own assessor records. A tract near the line by Saugus can be split in two county records, so check the adjacent map too. Out toward Zero, the Platbookmapper state page links each neighboring county map for Montana.
Using it on a phone
Most viewers work in a phone browser, useful out on a road near Zero, but coverage can be spotty out of town. A printout of the tract near Mildred is a good backup.
Questions to ask before you buy
For a home near Zero, ask the seller about past flood claims before closing; an insurance quote early avoids surprises.
Matching the zone to the lot lines
FEMA's map shows zones but not ownership, so check the Montana Cadastral too to confirm you have the right parcel near Zero.
Before you lean on the lines
If the land is near Saugus, the acreage figure is an assessed number; just a licensed surveyor establishes the real boundary on the ground. Around Zero, owner names and values update on a schedule, so a deed recorded last month may not show yet.
Getting answers from the right desk
Deeds, mortgages and recorded plats for land near Mildred are with the County Clerk and Recorder, usually searchable by name or document number. Questions about what you can build around Zero go to planning, building or health offices, and the answer depends on jurisdiction.
Lenders and permits
Out toward Zero, an Elevation Certificate from a surveyor helps: it compares the building to the BFE. New construction in a floodplain near Fallon often needs a floodplain permit; ask the local floodplain administrator early.
