Checking the Marshall County flood zone map step by step
For land near Englund, flood zones come from FEMA's Flood Map Service Center: enter the street address, and choose the dynamic map. Vacant ground around Florian is still easy to locate: zoom in from US Route 59 and click inside the land.
The free map to start with
Go first to the Marshall County parcel viewer; it maps each assessed parcel in the county, Agassiz National Wildlife Refuge included. Without an address in hand, pan along US Route 59 until the lines appear, then click inside the one you want, for land near Florian included. For a home near Englund, the record panel normally shows the owner of record, assessed acreage, the parcel number and in many cases the last transfer.
Places you'll see on the map
Warren holds the county offices, home to the main records offices. Smaller places on the map include Alvarado, Argyle, Grygla, and Holt. Roughly 8,810 people call Marshall County home (Census Bureau estimate, 2023) spread over roughly 1,775 square miles. Marshall County was formed in 1879, and some chains of title near Agassiz Wilderness are long. Places such as Agassiz National Wildlife Refuge are easy to spot when you zoom out.
Questions to ask before you buy
On ground around Agassiz National Wildlife Refuge, request whether the home has flooded before closing; getting a quote early avoids surprises.
What the zone letters mean
Zone AE includes a base flood elevation (BFE), which plain A zones lack; builders around Agassiz Wilderness design to it. With a lot near Agassiz Wilderness, a shaded X area marks moderate flood hazard, between the 1% and 0.2% annual chance floods; unshaded X is minimal risk.
Who handles what
Recorded documents for a parcel near Argyle are with the County Recorder, sometimes only in person. Questions about what you can build around Florian are for the local planning and health departments, depending on whether the land is inside town limits.
Use the county map alongside FEMA
If only part of a parcel near Englund is shaded, what matters is where the building sits.
Lenders and permits
Out toward Holt, ask for an Elevation Certificate: it can change the insurance price a lot. Building or adding on near Warren in a mapped zone often needs a floodplain permit; ask the local floodplain administrator before you plan.
Deeds, plats and who keeps them
Before you sign anything, get the recorded deed from the County Recorder; the parcel line is a drawing of it, whether the land is near Middle River or elsewhere in the county. If the land is near Newfolden, older tracts in the county can sit on several deeds, and a title company is worth hiring before a purchase.
Low spots and local drainage
Creeks and ditches near Argyle may not have detailed mapping, so walk the land after rain. Wetlands near Gatzke can limit building even outside a flood zone; check the National Wetlands Inventory mapper for a first look.
Land on the county line
Marshall County touches Beltrami County, Kittson County, Pennington County, Polk County, and Roseau County; every one of them runs a separate parcel map. Acreage along the edge near Gatzke can be split across two assessors' files, so open the neighboring map too. If the land is near Alvarado, our state page lists each neighboring county map for Minnesota.
Legal descriptions in Minnesota
Minnesota follows the Public Land Survey System, so rural legal descriptions near Warren cite section, township and range. Each section is nominally a mile square, about 640 acres, and a township holds 36 of them, though real sections near Agassiz National Wildlife Refuge vary in size. Write down the legal description for the tract near Florian when you talk to a surveyor.
On site with the map
The parcel map usually runs in a mobile browser, which helps when you're standing on land near Agassiz National Wildlife Refuge, though signal can drop in rural spots. A printout of the tract near Argyle is a good backup.
