Thinking about a house near Gattman? A quick look at the Monroe County flood zone map shows whether it sits in a FEMA flood zone, and the lookup is free. In this Monroe County guide: finding the address on FEMA's map, decoding A, AE and X, and confirming the outline on the county map.
Where the Monroe County flood zone map lives
Near Hatley, start with FEMA's Flood Map Service Center: enter the street address, then open the map view for that panel. Rural land near New Hamilton with no street number can still be found: zoom in from the nearest road then click the parcel area.
Getting to the right map
Property in and around Aberdeen appear on the Monroe County ArcGIS parcel map, which opens without registering. In and around Aberdeen, put in a street address, an owner's name or a parcel number, and the viewer zooms to the match. For a tract near Hatley, copy the parcel ID while you have it open; each office in the county asks for it first.
Offices that can help
Anything recorded against property around Athens are with the Chancery Clerk, often with an online index. Zoning, permits and septic questions near Smithville need the planning or permitting office, depending on whether the land is inside town limits.
Land on the county line
The county borders Lamar County, AL, Marion County, AL, Chickasaw County, Clay County, and Itawamba County, and each of those keeps its own parcel map, especially near Bigbee. Ground near New Hamilton that runs to the line can show up across two assessors' files, so check the neighboring map too. In and around New Hamilton, the Platbookmapper state page lists every bordering county map for Mississippi.
Water near New Hamilton
Creeks and ditches near Aberdeen aren't always studied in detail, so walk the land after rain. Marshy spots near Aberdeen can limit building too; check the National Wetlands Inventory mapper for a first look.
Reading A, AE and X
For land near New Hamilton, any A or V zone are Special Flood Hazard Areas, meaning a 1% or greater chance of flooding each year. For land near New Hamilton, minimal risk is not no risk: FEMA notes that many claims come from moderate- and low-risk areas.
Parcel lines plus flood zones
FEMA's map shows zones but not ownership, so open the Monroe County ArcGIS parcel map next to confirm you have the right parcel near Bigbee.
Monroe County in a few facts
Aberdeen holds the county offices, home to the main records offices. Other places on the map include Amory, Nettleton, Hatley, and Smithville. Roughly 33,609 people live in Monroe County (Census Bureau estimate, 2023) on roughly 765 square miles. The county was organized in 1821, so old deeds can run back a long way around Amory.
Reading the legal description
Mississippi follows the Public Land Survey System, which means a tract near Gattman is described by section, township and range. Each section is nominally a mile square, about 640 acres, and a township holds 36 of them, though sections near Aberdeen can be irregular. Copy the legal description from the record for the parcel near Bigbee before you request a deed or survey.
Insurance, lenders and building
If a building sits in a Special Flood Hazard Area and a federally regulated lender is involved, the lender will require flood insurance in communities in the NFIP, and that holds around New Hamilton too. New construction in a floodplain near New Hamilton usually means extra permit review; call the permitting office before you plan.
Taking the map into the field
Most viewers work in a phone browser, which helps when you're standing on land near Gattman, though signal can drop in rural spots. A saved image of the lot near Amory and its lines keeps working without signal.
Questions to ask before you buy
If the land is near Aberdeen, ask the seller for any Elevation Certificate before closing; an insurance quote early keeps the budget honest.
What the map can't tell you
The acreage figure is an estimate; only a licensed surveyor can set the real lines for a parcel near Bigbee. For a tract near Becker, records update in batches, so a deed recorded last month can take weeks to appear.
Frequently asked
How often are flood maps updated in Monroe County?
Good question; a new study can move a zone line near Athens; check the effective date on the panel.
Can I see flood zones on the county ArcGIS parcel map near Nettleton?
Usually, a flood layer may appear in the county ArcGIS parcel map layer list, though it can lag behind FEMA's current panels, at least around Hatley.
Is Zone X safe from flooding near Smithville?
Closer to Becker, shaded X is moderate risk and unshaded X is minimal risk, and floods still happen outside high-risk zones.
What is a LOMA around Bigbee?
For most people, you can ask FEMA for a LOMA if surveyed elevations show the building near Becker is above the BFE; a surveyor's elevation data supports it.
Does the parcel map work on a phone near Bigbee?
For a home near Gattman, no app is needed for most county viewers; screenshots help offline.

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.
