Ahead of any purchase around Big Lake National Wildlife Refuge, check the Mississippi County flood zone map: the zone on that map shapes insurance, permits and resale. This county guide covers: finding the address on FEMA's map, decoding A, AE and X, and pairing it with the county ArcGIS parcel map for land near Manila.
The Mississippi County flood zone map: start here
For acreage around Gosnell, start with FEMA's Flood Map Service Center: enter the street address, and choose the dynamic map. A tract near Luxora without an address is still easy to locate: zoom in from Interstate 55 and click inside the land.
Getting to the right map
Your first stop is the Mississippi County ArcGIS parcel map; it maps each tax parcel from Blytheville to Armorel. On ground around Joiner, enter a street address, an owner's name or a parcel number, and the matching parcel lights up. If the land is near Keiser, the parcel card normally shows the owner of record, assessed acreage, the parcel number and sometimes recent sales.
Next door to this county, at least around Big Lake National Wildlife Refuge.
The county touches Craighead County, Crittenden County, Poinsett County, Dunklin County, MO, and Pemiscot County, MO, and each of those keeps its own parcel map for land near Keiser. Ground near Armorel that runs to the line may be split in two county records, so look at the neighboring map before you assume the acreage. Near Armorel, the Platbookmapper state page links each neighboring county map for Arkansas.
Decoding the flood zone labels
On ground around Keiser, A and V zones are Special Flood Hazard Areas, meaning a 1% or greater chance of flooding each year. If you're looking near Manila, shaded Zone X marks moderate flood hazard, roughly the 100- to 500-year range; unshaded X is minimal risk.
Water near Luxora
Low-lying fields near Osceola aren't always studied in detail, so ask neighbors about past flooding. Wet ground around Armorel is a separate issue from flood zones; the National Wetlands Inventory mapper shows mapped wetlands.
Use the county map alongside FEMA
FEMA's map shows zones but not ownership, so check the Mississippi County ArcGIS parcel map too for the outline of the tract near Big Lake National Wildlife Refuge.
What a flood zone means for a buyer
Closer to Armorel, an Elevation Certificate from a surveyor helps: it records the building's elevation against the base flood. Building or adding on near Blytheville in a mapped zone often needs a floodplain permit; check with the county or town building office early.
Sections, lots and bearings
Arkansas uses the Public Land Survey System, which means a tract near Leachville 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 Luxora can be irregular. Write down the legal description for the tract near Joiner when you talk to a surveyor.
What to request from a seller
For land near Leachville, request whether the home has flooded before closing; an insurance quote early avoids surprises.
Taking the map into the field
Most viewers work in a phone browser, handy when you're parked on a road near Armorel, but coverage can be spotty out of town. A printout of the tract near Manila keeps working without signal.
Deeds, plats and who keeps them
For acreage around Gosnell, the map is an index, not the title: recorded deeds, subdivision plats and easements for parcels in the county are kept by the Circuit Clerk. For acreage around Gosnell, have ready the instrument number from the tax record and the lookup takes minutes.
A quick look at the area
Blytheville is the county seat, home to the main records offices. Smaller places on the map include Osceola, Gosnell, Joiner, and Keiser, where town lots give way to larger tracts. About 38,663 people call Mississippi County home (Census estimate, 2023) on roughly 902 square miles. Mississippi County was organized in 1833, which matters when you trace an old farm's title. Places such as Big Lake National Wildlife Refuge make handy reference points on the map.
A word on accuracy
If the land is near Osceola, acreage on the record is an assessed number; only a licensed surveyor establishes the real boundary on the ground. For acreage around Leachville, owner names and values update on a schedule, so a deed recorded last month can take weeks to appear.
