Before you buy or build near Lavaca, look at the Greenwood flood zone map: the zone on that map shapes insurance, permits and resale. What this Greenwood guide covers: locating a parcel on FEMA's map, decoding A, AE and X, and pairing it with the Sebastian County ArcGIS parcel map.
Where the Greenwood flood zone map lives
Flood zones come from FEMA's Flood Map Service Center: search an address around Bonanza, and choose the dynamic map. Rural land near Barling with no street number is still easy to locate: search the nearest road then click the parcel area.
The viewer Sebastian County publishes
Go first to the Sebastian County ArcGIS parcel map; it includes every assessed parcel from Barling to Bonanza. Closer to Fort Smith, type a street address, an owner's name or a parcel number, and the matching parcel lights up. Closer to Bonanza, the parcel card typically gives the owner of record, acreage on the tax roll, the parcel number and in many cases the last transfer.
Sections, lots and bearings
Arkansas is laid out under the Public Land Survey System, so deeds around Bonanza reference sections and townships. A standard section is about one square mile, roughly 640 acres, with 36 sections to a township, though corrections make some sections near Central City odd-sized. Write down the legal description for the tract near Hackett for any title or survey request.
Field tips
Most viewers work in a phone browser, which helps when you're standing on land near Fort Smith, though signal can drop in rural spots. A saved image of the lot near Central City and its lines is a good backup.
Where Greenwood fits in
Greenwood lies within Sebastian County, Arkansas, which means parcel data comes from the county. As the county seat, Greenwood hosts the courthouse, handy when you need recorded documents. For land near Lavaca, the municipality handles things like zoning, permits and utilities for lots inside the boundary, and the county still keeps the parcel and deed records. Acreage past the city limits out by Barling usually answers to county rules rather than the town's.
Water near Bonanza
Low-lying fields near Lavaca may not have detailed mapping, so walk the land after rain. Marshy spots near Central City can limit building too; the National Wetlands Inventory mapper shows mapped wetlands.
Zones on the Greenwood flood zone map
For a parcel near Central City, any A or V zone are Special Flood Hazard Areas, land with a 1-percent chance of flooding in any year. For land near Hackett, a shaded X area marks moderate flood hazard, roughly the 100- to 500-year range; plain X, or C on older maps, is minimal risk.
Offices that can help
Anything recorded against property around Bonanza sit in the index kept by the Circuit Clerk, sometimes only in person. Questions about what you can build around Bonanza are for the local planning and health departments, town or county, depending on location.
Before you lean on the lines
Tax maps are drawn for assessment, not measured on the ground, so a fence near Bonanza may sit some distance off the line on screen. Records update in batches, so a fresh transfer around Hackett may not show yet.
Deeds, plats and who keeps them
The map is an index, not the title: deeds, plats and easements covering ground around Hackett are kept by the Circuit Clerk. Long-held tracts near Bonanza can go back through a long string of deeds, and a title company can sort it out before a purchase.
A quick look at the area
Fort Smith is the county seat, where most land records are kept. Other places on the map include Barling, Central City, Bonanza, and Hackett. Around 129,098 people live in Sebastian County (Census estimate, 2023) across some 531 square miles. Sebastian County was formed in 1851, and some chains of title near Barling are long. Landmarks such as Ouachita National Forest are easy to spot when you zoom out from Fort Smith.
Use the county map alongside FEMA
FEMA's map shows zones but not ownership, so pair it with the Sebastian County ArcGIS parcel map to see exactly which lot near Central City you're looking at.
Questions to ask before you buy
Request for any Elevation Certificate on the property near Lavaca; an insurance quote early keeps the budget honest.
Insurance, lenders and building
For acreage around Central City, ask for an Elevation Certificate: it compares the building to the BFE. Remodeling a house in a zone near Hackett can trigger elevation rules; check with the county or town building office early.
Quick answers
Can a flood zone near Lavaca change?
Good question; zones near Central City can shift when FEMA updates a panel; check the effective date on the panel.
What is a base flood elevation in Greenwood?
It depends, but a BFE near Hackett tells builders how high the lowest floor should be; surveyors near Fort Smith use it often.
Is AE a high-risk flood zone in Greenwood?
Good question; AE is a Special Flood Hazard Area with a published base flood elevation, which shapes building rules near Bonanza.
Can I challenge a flood zone near Lavaca?
In most cases, you can ask FEMA for a LOMA if surveyed elevations show the building near Hackett is above the BFE; it starts with an elevation survey.
Does the parcel map work on a phone around Barling?
Most viewers run in a mobile browser; load it before you lose coverage near Lavaca.

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.
