Before an offer near Sherburn, pull up the Fairmont flood map: FEMA's zone label affects insurance, permits and resale. Covered here for Fairmont: locating a parcel on FEMA's map, decoding A, AE and X, and pairing it with the Martin County Beacon site.
Where the Fairmont flood map lives
The official source is FEMA's Flood Map Service Center: search an address around Welcome, and choose the dynamic map. Rural land near Welcome with no street number can still be found: zoom in from the nearest road and click the spot.
Getting to the right map
The public parcel map for this area is the Martin County Beacon site, and no login is needed to use it. Out toward Northrop, enter a street address, an owner's name or a parcel number, and the viewer zooms to the match. On ground around Sherburn, the record panel usually lists the owner of record, acreage on the tax roll, a parcel ID and in many cases the last transfer.
Backing up the map with records
The map is an index, not the title: deeds, subdivision plats and easements for land near Truman are filed with the County Recorder. For property near Ceylon, have ready the book and page from the tax record and the lookup takes minutes.
Reading the legal description
Minnesota follows the Public Land Survey System, so deeds around Northrop 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 Northrop odd-sized. Write down the legal description for the tract near Welcome before you request a deed or survey.
Where Fairmont fits in
Fairmont sits in Martin County, Minnesota, which means parcel data comes from the county. Fairmont is also the county seat, so deeds and plats are filed in town. For land near Truman, the municipality handles things like zoning, permits and utilities within town limits, but the county runs assessment and recording. Lots just outside the town limits near Sherburn generally answers to county rules, not municipal ones.
Water near Welcome
Low-lying fields near Sherburn aren't always studied in detail, so ask neighbors about past flooding. Marshy spots near Ceylon can limit building too; the National Wetlands Inventory mapper shows mapped wetlands.
What the zone letters mean
For land near Sherburn, any A or V zone are Special Flood Hazard Areas, land with a 1-percent chance of flooding in any year. On ground around Sherburn, a shaded X area is moderate risk, roughly the 100- to 500-year range; unshaded X means minimal mapped risk.
A quick look at the area
Fairmont holds the county offices, which is where the courthouse records live. Other places on the map include Northrop, Granada, Welcome, and Ceylon, each with its own cluster of lots. Roughly 19,657 people call Martin County home (Census Bureau estimate, 2023) across some 712 square miles. Martin County dates to 1857, and some chains of title near Granada are long.
Matching the zone to the lot lines
FEMA doesn't draw property lines, so pair it with the Martin County Beacon site to see exactly which lot near Ceylon you're looking at.
Land on the county line
Martin County borders Emmet County, IA, Kossuth County, IA, Blue Earth County, Faribault County, and Jackson County; every one of them runs a separate parcel map. Acreage along the edge near Truman can be split across two assessors' files, so check the neighboring map as well. For a parcel near Granada, our state page lists every neighboring county map for Minnesota.
Money questions tied to the zone
For a structure inside an A or V zone and a federally regulated lender is involved, flood insurance is generally required in communities in the NFIP, which applies near Truman as much as anywhere. Remodeling a house in a zone near Sherburn usually means extra permit review; check with the county or town building office before you plan.
Questions to ask before you buy
Ask the listing agent whether the home has flooded on the property near Truman; getting a quote early avoids surprises.
Taking the map into the field
Most viewers work in a phone browser, which helps when you're standing on land near Ceylon, but coverage can be spotty out of town. A saved image of the lot near Welcome and its lines keeps working without signal.

Not a survey. County GIS and tax parcel maps are assessment and planning layers. They are not a substitute for a recorded plat, deed, or licensed survey, especially for fences, setbacks, or boundary disputes.
