Ahead of any purchase around North River, check the Fargo flood map: FEMA's zone label affects insurance, permits and resale. In this city guide: locating a parcel on FEMA's map, reading the zone codes, and pairing it with the Cass County ArcGIS parcel map for land near Arthur.
Getting started with the Fargo flood map
The official source is FEMA's Flood Map Service Center: type an address near West Fargo, then open the map view for that panel. A tract near Frontier without an address can still be found: pan from the closest town then click the parcel area.
The viewer Cass County publishes
Begin with the Cass County ArcGIS parcel map; it maps every assessed parcel from Frontier to North River. In and around Briarwood, put in a street address, an owner's name or a parcel number, and the viewer zooms to the match. Out toward North River, the parcel card normally shows the owner of record, assessed acreage, the parcel number and sometimes recent sales.
Where Fargo fits in
The city lies within Cass County, North Dakota, which means parcel data comes from the county for land near Alice. As the county seat, Fargo hosts the courthouse, which puts the County Recorder close by. Closer to Prairie Rose, city or town hall handles things like zoning, permits and utilities for lots inside the boundary, while the county keeps the tax map. Acreage past the town limits toward Frontier often follows county rules, not municipal ones.
Beyond the mapped zones
Creeks and ditches near West Fargo may not have detailed mapping, so walk the land after rain. Marshy spots near West Fargo can limit building too; check the National Wetlands Inventory mapper for a first look.
Places you'll see on the map
The city serves as the county seat, where most land records are kept, at least around Arthur. Smaller places on the map include Prairie Rose, West Fargo, Frontier, and Reile's Acres. Roughly 196,362 people call Cass County home (Census estimate, 2023) across roughly 1,765 square miles. Cass County was organized in 1873, and some chains of title near North River are long. Features like Red River of the North help you orient on the aerial around North River.
A word on accuracy
Acreage on the record is a tax-roll number; only a licensed surveyor can set the real boundary on land around Briarwood. With a lot near Reile's Acres, owner names and values update on a schedule, so a deed recorded last month might lag behind.
What the zone letters mean
An AE label carries a published BFE, which plain A zones lack; that elevation drives building rules near Prairie Rose. For a home near Frontier, a shaded X area is moderate risk, between the 1% and 0.2% annual chance floods; plain X, or C on older maps, means minimal mapped risk.
Deeds, plats and who keeps them
For anything that matters, get the recorded deed from the County Recorder; the parcel map near North River only summarizes it. Inherited tracts around Reile's Acres can go back through a long string of deeds, so a title company is worth hiring before a purchase.
Using it on a phone
The parcel map usually runs in a mobile browser, useful out on a road near Briarwood, so load it before you lose signal. A saved image of the lot near Prairie Rose and its lines keeps working without signal.
A short flood checklist
Ask the listing agent about past flood claims for the house near Prairie Rose; getting a quote early keeps the budget honest.
Matching the zone to the lot lines
FEMA doesn't draw property lines, so check the Cass County ArcGIS parcel map too for the outline of the tract near West Fargo.
Legal descriptions in North Dakota
North Dakota follows the Public Land Survey System, which means a tract near Frontier is described by section, township and range. Each section is nominally a mile square, about 640 acres, with 36 sections to a township, though sections near West Fargo can be irregular. Write down the legal description for the tract near North River when you talk to a surveyor.
Lenders and permits
For a parcel near West Fargo, get the Elevation Certificate if one exists: it compares the building to the BFE. Building or adding on near Reile's Acres in a mapped zone often needs a floodplain permit; ask the local floodplain administrator early.
Fargo: common questions
Do I need to worry about flooding in Zone X near Reile's Acres?
Shaded X is moderate risk and unshaded X is minimal risk; many owners near Frontier buy coverage anyway.
Does the county parcel map show flood zones for land near Frontier?
Short answer: a flood layer may appear in the Cass County ArcGIS parcel map layer list, but FEMA's own map is the official source.
How often are flood maps updated near Prairie Rose?
For most people, a new study can move a zone line near Frontier; check the effective date on the panel.
What is a LOMA near Reile's Acres?
Usually, you can ask FEMA for a LOMA if surveyed elevations show the building near Frontier is above the BFE, and lenders accept the result.
Is the parcel map a survey for land near Prairie Rose?
No; boundary questions near Prairie Rose need a licensed surveyor; a survey sets the real corners

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.
