Ahead of any purchase around Underwood, look at the Fergus Falls flood zone map: FEMA's zone label affects insurance, building rules and resale. What this Fergus Falls guide covers: locating a parcel on FEMA's map, reading the zone codes, and pairing it with the Otter Tail County ArcGIS parcel map.
The Fergus Falls flood zone map: start here
The official source is FEMA's Flood Map Service Center: search an address around Elizabeth, and pick the FIRMette or map view. Rural land near Erhard with no street number is still easy to locate: pan from the closest town and click inside the land.
The free map to start with
Property in and around Underwood are published on the Otter Tail County ArcGIS parcel map, which opens without registering. On ground around Pelican Rapids, type a street address, an owner's name or a parcel number, and the viewer zooms to the match. For acreage around Erhard, the record panel typically gives the owner of record, assessed acreage, the parcel number and in many cases the last transfer.
Getting answers from the right desk
If the acreage or value on a parcel near Rothsay looks off are handled by the County Assessor, which maintains the tax roll. Questions about what you can build around Underwood are for the local planning and health departments, town or county, depending on location.
Getting your bearings
Fergus Falls is the county seat, where most land records are kept. Other places on the map include Elizabeth, Underwood, Dalton, and Erhard, where town lots give way to larger tracts. About 60,626 people live in Otter Tail County (Census estimate, 2023) spread over some 1,972 square miles. Otter Tail County dates to 1858, so old deeds can run back a long way. Landmarks such as Otter Tail River, Red River of the North, and Glendalough State Park make handy reference points on the map near Dalton.
How land is described here
Minnesota is laid out under the Public Land Survey System, which means a tract near Elizabeth is described by section, township and range. Each section is nominally a mile square, about 640 acres, with 36 sections to a township, though corrections make some sections near Underwood odd-sized. Keep the legal description for land near Pelican Rapids for any title or survey request.
Fergus Falls, MN: the basics
Fergus Falls is part of Otter Tail County, Minnesota, and the county assessor maps its lots. As the county seat, Fergus Falls hosts the courthouse, so deeds and plats are filed in town. On ground around Pelican Rapids, city or town hall 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 toward Pelican Rapids often answers to county rules, not municipal ones.
Decoding the flood zone labels
Zone AE comes with a base flood elevation, which plain A zones lack; that elevation drives building rules near Underwood. In and around Underwood, minimal risk is not no risk: FEMA notes that many claims come from moderate- and low-risk areas.
Lining it up with the parcel map
FEMA's map shows zones but not ownership, so check the Otter Tail County ArcGIS parcel map too to confirm you have the right parcel near Elizabeth.
Insurance, lenders and building
For a structure inside an A or V zone and a federally regulated lender is involved, the lender will require flood insurance in communities in the NFIP, which applies near Dalton as much as anywhere. Building or adding on near Erhard in a mapped zone often needs a floodplain permit; check with the county or town building office early.
Water near Rothsay
Low-lying fields near Pelican Rapids aren't always studied in detail, so walk the land after rain. Wet ground around Rothsay is a separate issue from flood zones; check the National Wetlands Inventory mapper for a first look.
Taking the map into the field
The parcel map usually runs in a mobile browser, useful out on a road near Underwood, but coverage can be spotty out of town. A screenshot of the parcel near Erhard with its ID keeps working without signal.
Questions to ask before you buy
Ask the listing agent whether the home has flooded for the house near Elizabeth; an insurance quote early keeps the budget honest.
Recorded documents worth pulling
For anything that matters, get the recorded deed through the County Recorder; the parcel map near Erhard only summarizes it. With a lot near Rothsay, have ready the book and page shown in the record panel and the lookup takes minutes.
