Before an offer near Southaven, check the Hernando flood zone map: the zone on that map shapes insurance, permits and resale. This Hernando guide covers: locating a parcel on FEMA's map, decoding A, AE and X, and pairing it with the DeSoto County ArcGIS parcel map.
The Hernando flood zone map: start here
The official source is FEMA's Flood Map Service Center: search an address around Horn Lake, then open the map view for that panel. Vacant ground around Olive Branch is still easy to locate: search the nearest road and click the spot.
Opening the official parcel viewer
Go first to the DeSoto County ArcGIS parcel map; it maps each tax parcel around Southaven and Horn Lake. In and around Horn Lake, type a street address, an owner's name or a parcel number, and the matching parcel lights up. If the land is near Olive Branch, write down the parcel ID while you have it open; every clerk in the county asks for it first.
Legal descriptions in Mississippi
Mississippi follows the Public Land Survey System, so rural legal descriptions near Olive Branch cite section, township and range. Each section is nominally a mile square, about 640 acres, with 36 sections to a township, though corrections make some sections near Horn Lake odd-sized. Write down the legal description for the tract near Olive Branch when you talk to a surveyor.
Hernando, MS: the basics
Hernando is part of DeSoto County, Mississippi, and the county assessor maps its lots. As the county seat, Hernando hosts the courthouse, so deeds and plats are filed in town. On ground around Horn Lake, 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 Olive Branch often answers to county rules instead.
On site with the map
Most viewers work in a phone browser, which helps when you're standing on land near Horn Lake, though signal can drop in rural spots. A screenshot of the parcel near Horn Lake with its ID keeps working without signal.
Decoding the flood zone labels
Zone AE carries a published BFE, and an unnumbered A zone has none; builders around Horn Lake design to it. For land near Southaven, shaded Zone X is moderate risk, between the 1% and 0.2% annual chance floods; plain X, or C on older maps, is minimal risk.
Land on the county line
DeSoto County meets Crittenden County, AR, Marshall County, Tate County, Tunica County, and Shelby County, TN, and each of those keeps its own parcel map. Ground near Olive Branch that runs to the line may show up across two assessors' files, so check the neighboring map too. For a parcel near Horn Lake, our state page links every bordering county map for Mississippi.
Use the county map alongside FEMA
FEMA's map shows zones but not ownership, so open the DeSoto County ArcGIS parcel map next for the outline of the tract near Horn Lake.
Questions to ask before you buy
Ask the listing agent for any Elevation Certificate for the house near Olive Branch; getting a quote early keeps the budget honest.
What a flood zone means for a buyer
With a lot near Horn Lake, an Elevation Certificate from a surveyor helps: it compares the building to the BFE. Remodeling a house in a zone near Olive Branch often needs a floodplain permit; call the permitting office early.
Water near Horn Lake
Low-lying fields near Southaven aren't always studied in detail, so ask neighbors about past flooding. Marshy spots near Walls can limit building too; check the National Wetlands Inventory mapper for a first look.
Before you lean on the lines
The acreage figure is an assessed number; only a licensed surveyor sets the real boundary for a parcel near Olive Branch. On ground around Walls, owner names and values update on a schedule, so a deed recorded last month might lag behind.
Offices that can help
Recorded documents for a parcel near Southaven come from the Chancery Clerk, often with an online index. Questions about what you can build around Southaven go to planning, building or health offices, depending on whether the land is inside town limits.

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.
