Before you buy or build near Manvel, check the Grand Forks flood map: FEMA's zone label affects insurance, building rules and resale. What this Grand Forks guide covers: finding the address on FEMA's map, decoding A, AE and X, and pairing it with the Grand Forks County ArcGIS parcel map.
Getting started with the Grand Forks flood map
Start with FEMA's Flood Map Service Center: search an address around Thompson, and pick the FIRMette or map view. Rural land near Manvel with no street number can still be found: zoom in from the nearest road and click the spot.
Opening the official parcel viewer
Lots and tracts near Reynolds can be looked up on the Grand Forks County ArcGIS parcel map, free to use and open without a login. Closer to Gilby, put in a street address, an owner's name or a parcel number, and the viewer zooms to the match. For property near Thompson, the record panel typically gives the owner of record, assessed acreage, the parcel number and often a sale date.
Legal descriptions in North Dakota
North Dakota follows the Public Land Survey System, so deeds around Inkster reference sections and townships. Each section is nominally a mile square, about 640 acres, and a township holds 36 of them, though sections near Thompson can be irregular. Keep the legal description for land near Gilby before you request a deed or survey.
Grand Forks County in a few facts
Grand Forks serves as the county seat, where most land records are kept. You'll also find Thompson, Manvel, Emerado, and Reynolds. Roughly 72,708 people live in Grand Forks County (Census estimate, 2023) spread over roughly 1,436 square miles. Grand Forks County dates to 1873, so old deeds can run back a long way. Features like Red River of the North, Forest River, and Kellys Slough National Wildlife Refuge help you orient on the aerial around Gilby.
A short flood checklist
Request for any Elevation Certificate for the house near Reynolds; an insurance quote early avoids surprises.
Neighboring parcel maps
Grand Forks County borders Marshall County, MN, Polk County, MN, Nelson County, Steele County, and Traill County; every one of them runs a separate parcel map. Acreage along the edge near Emerado may be split in two county records, so look at the adjacent map too. On ground around Emerado, the Platbookmapper state page links each neighboring county map for North Dakota.
City limits and county records
Grand Forks lies within Grand Forks County, North Dakota, and the county assessor maps its lots. As the county seat, Grand Forks hosts the courthouse, so deeds and plats are filed in town. If you're looking near Reynolds, the municipality handles matters such as zoning, permits and utilities for lots inside the boundary, but the county runs assessment and recording. Land beyond the town limits toward Manvel generally answers to county rules rather than the town's.
Beyond the mapped zones
Low-lying fields near Thompson may not have detailed mapping, so walk the land after rain. Wet ground around Emerado is a separate issue from flood zones; check the National Wetlands Inventory mapper for a first look.
What the zone letters mean
An AE label carries a published BFE, and an unnumbered A zone has none; builders around Reynolds design to it. Out toward Thompson, shaded Zone X marks moderate flood hazard, between the 1% and 0.2% annual chance floods; unshaded X is minimal risk.
Use the county map alongside FEMA
FEMA doesn't draw property lines, so check the Grand Forks County ArcGIS parcel map too to confirm you have the right parcel near Gilby.
What a flood zone means for a buyer
If a building sits in a Special Flood Hazard Area and a federally regulated lender is involved, flood insurance is generally required where the community participates in the National Flood Insurance Program, which applies near Reynolds as much as anywhere. Remodeling a house in a zone near Inkster often needs a floodplain permit; ask the local floodplain administrator early.
A word on accuracy
Tax maps are drawn for assessment, not measured on the ground, so a fence near Inkster may sit a few yards off the line on screen. In and around Inkster, owner names and values update on a schedule, so a deed recorded last month might lag behind.
Questions about the Grand Forks flood map
Where can I see the Grand Forks flood map for free?
Good question; FEMA's free map shows the zone for any spot near Reynolds, and the zone code appears on the map.
Can I see flood zones on the county ArcGIS parcel map near Manvel?
A flood layer may appear in the county ArcGIS parcel map layer list, but FEMA's own map is the official source around Manvel.
How often are flood maps updated in Grand Forks?
In most cases, zones near Emerado can shift when FEMA updates a panel, so look at the panel date.
What is a base flood elevation for land near Emerado?
Good question; the base flood elevation is the water level expected in the 1% annual chance flood; surveyors near Gilby use it often.
What's the tax parcel number used for in Grand Forks?
It's the number the Director of Tax Equalization uses to track a tract near Emerado, and it's on the record panel and tax bills.

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.
