Before an offer near White River National Wildlife Refuge, look at the Desha County flood zone map: a mapped flood zone changes insurance, building rules and resale. What this county guide covers: locating a parcel on FEMA's map, decoding A, AE and X, and confirming the outline on the county map, especially near McGehee.
The Desha County flood zone map: start here
If the land is near Tillar, start with FEMA's Flood Map Service Center: enter the street address, and pick the FIRMette or map view. Vacant ground around Kelso is still easy to locate: zoom in from Interstate 69 then click the parcel area.
Pulling up a parcel
Your first stop is the Desha County ArcGIS parcel map; it covers each assessed parcel in the county, Dumas included. When a rural tract has no street number, pan along Interstate 69 and click the parcel itself. For a tract near Arkansas City, write down the parcel ID before closing the panel; every records desk in the county will want it.
Desha County in a few facts
You'll also find Arkansas City, Dumas, McGehee, and Mitchellville, where town lots give way to larger tracts. About 10,479 people call Desha County home (Census estimate, 2023) across about 741 square miles. Desha County was organized in 1838, so old deeds can run back a long way. Features like White River National Wildlife Refuge help you orient on the aerial.
A word on accuracy
In and around Halley, the acreage figure is an estimate; only a licensed surveyor establishes the real lines on the ground. If the land is near Arkansas City, owner names and values update on a schedule, so a deed recorded last month can take weeks to appear.
Recorded documents worth pulling
If you're looking near Dumas, the map is an index, not the title: recorded deeds, plats and easements for parcels in the county are kept by the Circuit Clerk. For land near Pickens, use the document number shown in the record panel and the lookup takes minutes.
Questions to ask before you buy
Ask the listing agent about past flood claims on the property near Kelso; an insurance quote early keeps the budget honest.
Taking the map into the field
The parcel map usually runs in a mobile browser, which helps when you're standing on land near McGehee, though signal can drop in rural spots. A screenshot of the parcel near Pea Ridge with its ID helps when you meet an owner or agent.
What the zone letters mean
Zone AE includes a base flood elevation (BFE), and an unnumbered A zone has none; surveyors near Back Gate use that number. For a tract near White River National Wildlife Refuge, shaded Zone X marks moderate flood hazard, roughly the 100- to 500-year range; unshaded X means minimal mapped risk.
Next door to the county around Mitchellville.
The county meets Arkansas County, Chicot County, Drew County, Lincoln County, and Phillips County, all with their own assessor records, especially near Halley. Ground near Tillar that runs to the line can show up in two county records, so open the adjacent map too. On ground around McGehee, our state page links each neighboring county map for Arkansas.
Matching the zone to the lot lines
FEMA's map shows zones but not ownership, so pair it with the Desha County ArcGIS parcel map to see exactly which lot near White River National Wildlife Refuge you're looking at.
What a flood zone means for a buyer
If you're looking near Arkansas City, an Elevation Certificate from a surveyor helps: it can change the insurance price a lot. Remodeling a house in a zone near Kelso can trigger elevation rules; call the permitting office early.
Low spots and local drainage
Small streams around Mitchellville may not have detailed mapping, so ask neighbors about past flooding. Wet ground around White River National Wildlife Refuge is a separate issue from flood zones; check the National Wetlands Inventory mapper for a first look.
Which office to call
Questions about value or the owner field for land near Dumas go to the County Assessor, since that office keeps the assessment data. Building or septic questions for a lot near Tillar need the planning or permitting office, and the answer depends on jurisdiction.
Questions about the Desha County flood zone map
Do I need flood insurance near Kelso?
In most cases, for a building near Arkansas City in an A or V zone with a federally backed or regulated mortgage, it's generally required, in communities that take part in the NFIP.
Is AE a high-risk flood zone around McGehee?
It depends, but an AE zone has a 1% annual chance of flooding and a base flood elevation, so builders near White River National Wildlife Refuge design to that elevation.
Can I see flood zones on the Desha County ArcGIS parcel map?
For most people, a flood layer may appear in the county ArcGIS parcel map layer list; confirm a lot near Pea Ridge on FEMA's map either way.
How do I check the flood zone for an address near Pickens?
Good question; FEMA's free map shows the zone for any spot near Watson; then confirm the parcel on the county viewer.
What's the tax parcel number used for around Arkansas City?
Every office uses it to pull the same file for land near Watson; you'll see it in the viewer and on tax statements.
