Before you buy or build near Bonanza, look at the Sebastian 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, reading the zone codes, and pairing it with the county ArcGIS parcel map for land near Ouachita National Forest.
Where the Sebastian County flood zone map lives
If you'd rather pan and zoom, use the National Flood Hazard Layer viewer, which lets you click a spot and read its zone, and that holds around Huntington too. Vacant ground around Lavaca can still be found: zoom in from Interstate 49 then click the parcel area.
Opening the official parcel viewer
Your first stop is the Sebastian County ArcGIS parcel map; it includes every assessed parcel in the county, Fort Smith included. For land near Lavaca, put in a street address, an owner's name or a parcel number, then pick the result to center the map on it. In and around Fort Smith, copy the parcel ID while you have it open; each clerk in the county uses it to find the file.
Water near Barling
Creeks and ditches near Lavaca aren't always studied in detail, so look for water marks and debris lines. Wetlands near Hartford can limit building even outside a flood zone; check the National Wetlands Inventory mapper for a first look.
Zones on the Sebastian County flood zone map
For a home near Lavaca, zones beginning with A or V mark the Special Flood Hazard Area, meaning a 1% or greater chance of flooding each year. For acreage around Hackett, a shaded X area is moderate risk, between the 1% and 0.2% annual chance floods; unshaded X means minimal mapped risk.
A word on accuracy
Out toward Hackett, acreage on the record is a tax-roll number; only a licensed surveyor sets the real corners on the ground. If the land is near Barling, records update in batches, so a deed recorded last month might lag behind.
Matching the zone to the lot lines
FEMA doesn't draw property lines, so open the Sebastian County ArcGIS parcel map next to see exactly which lot near Hartford you're looking at.
Sections, lots and bearings
Arkansas follows the Public Land Survey System, so deeds around Huntington reference sections and townships. A standard section is about one square mile, roughly 640 acres, and a township holds 36 of them, though corrections make some sections near Bonanza odd-sized. Keep the legal description for land near Greenwood before you request a deed or survey.
Where the recorded documents are
For anything that matters, get the recorded deed through the Circuit Clerk; the parcel line is a drawing of it, and that holds around Barling too. If the land is near Bonanza, use the book and page shown in the record panel so staff can find the deed fast.
Taking the map into the field
The parcel map usually runs in a mobile browser, which helps when you're standing on land near Ouachita National Forest, but coverage can be spotty out of town. A saved image of the lot near Lavaca and its lines keeps working without signal.
What a flood zone means for a buyer
For a home near Hackett, ask for an Elevation Certificate: it compares the building to the BFE. Remodeling a house in a zone near Greenwood can trigger elevation rules; call the permitting office before you plan.
Getting your bearings
Fort Smith serves as the county seat, home to the main records offices. You'll also find Greenwood, Barling, Bonanza, and Hackett, where town lots give way to larger tracts. Around 129,098 people call Sebastian County home (Census estimate, 2023) across about 531 square miles. Sebastian County was organized in 1851, so old deeds can run back a long way. Landmarks such as Ouachita National Forest make handy reference points on the map.
What to request from a seller
On ground around Huntington, ask the listing agent whether the home has flooded before closing; getting a quote early avoids surprises.
Neighboring parcel maps
Sebastian County touches Crawford County, Franklin County, Logan County, Scott County, and Le Flore County, OK, and each of those keeps its own parcel map. A tract near the line by Bonanza can show up in two county records, so look at the adjacent map too. For a parcel near Huntington, our state page lists every bordering county map for Arkansas.

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.
