Weighing a property around Walls? A quick look at the Southaven flood zone map shows whether the lot falls inside a mapped floodplain, and it costs nothing to check. This Southaven guide covers: finding the address on FEMA's map, decoding A, AE and X, and pairing it with the DeSoto County ArcGIS parcel map.
Getting started with the Southaven flood zone map
Flood zones come from FEMA's Flood Map Service Center: type an address near Horn Lake, then open the map view for that panel. Vacant ground around Walls is still easy to locate: zoom in from Interstate 269 and click the spot.
Pulling up a parcel
Your first stop is the DeSoto County ArcGIS parcel map; it includes every assessed parcel from Horn Lake to Walls. Without an address in hand, follow Interstate 269 on the aerial until the lines appear, then click inside the one you want. For acreage around Hernando, write down the parcel ID from that panel; each records desk in the county asks for it first.
Water near Horn Lake
Creeks and ditches near Hernando may not have detailed mapping, so look for water marks and debris lines. Marshy spots near Olive Branch can limit building too; check the National Wetlands Inventory mapper for a first look.
Where Southaven fits in
Southaven sits in DeSoto County, Mississippi, so its parcels are on the county's map. For property near Olive Branch, city or town hall handles things like zoning, permits and utilities for lots inside the boundary, and the county still keeps the parcel and deed records. Land beyond the town limits out by Horn Lake generally falls under county rules instead.
A short flood checklist
Request whether the home has flooded on the property near Hernando; getting a quote early keeps the budget honest.
Who handles what
If the acreage or value on a parcel near Olive Branch looks off go to the County Tax Assessor, the office behind the parcel record. Building or septic questions for a lot near Hernando go to planning, building or health offices, town or county, depending on location.
Field tips
Most viewers work in a phone browser, which helps when you're standing on land near Walls, so load it before you lose signal. A printout of the tract near Walls keeps working without signal.
Limits of the parcel data
Listed acreage is an assessed number; just a licensed surveyor establishes the real corners for a parcel near Hernando. For a home near Hernando, records update in batches, so a deed recorded last month can take weeks to appear.
Places you'll see on the map
Hernando serves as the county seat, which is where the courthouse records live. Other places on the map include Horn Lake, Olive Branch, and Walls. About 193,247 people live in DeSoto County (Census Bureau estimate, 2023) spread over about 476 square miles. DeSoto County was formed in 1836, so old deeds can run back a long way.
Reading A, AE and X
Zone AE carries a published BFE, which plain A zones lack; builders around Horn Lake design to it. Out toward Hernando, shaded Zone X is moderate risk, between the 1% and 0.2% annual chance floods; unshaded X is minimal risk.
Parcel lines plus flood zones
FEMA doesn't draw property lines, so open the DeSoto County ArcGIS parcel map next to confirm you have the right parcel near Horn Lake.
Land on the county line
DeSoto County borders Crittenden County, AR, Marshall County, Tate County, Tunica County, and Shelby County, TN; every one of them runs a separate parcel map. A tract near the line by Hernando can show up across two assessors' files, so check the adjacent map as well. For land near Hernando, our state page lists every bordering county map for Mississippi.
Legal descriptions in Mississippi
Mississippi uses the Public Land Survey System, which means a tract near Walls is described by section, township and range. A standard section is about one square mile, roughly 640 acres, and a township holds 36 of them, though sections near Hernando can be irregular. Write down the legal description for the tract near Walls before you request a deed or survey.
Insurance, lenders and building
With a lot near Horn Lake, get the Elevation Certificate if one exists: it can change the insurance price a lot. New construction in a floodplain near Hernando often needs a floodplain permit; check with the county or town building office early.
