Ahead of any purchase around Myrtlewood, check the Marengo County flood zone map: a mapped flood zone changes insurance, building rules and resale. Covered here for the county: locating a parcel on FEMA's map, decoding A, AE and X, and pairing it with the AlabamaGIS / Flagship GIS - Marengo County Revenue Commission public GIS for land near Linden.
Getting started with the Marengo County flood zone map
Out toward Aimwell, flood zones come from FEMA's Flood Map Service Center: enter the street address, and pick the FIRMette or map view. Vacant ground around Linden can still be found: zoom in from the nearest road and click the spot.
The viewer Marengo County publishes
Lots and tracts near Dayton appear on the AlabamaGIS / Flagship GIS - Marengo County Revenue Commission public GIS, free to use and open without a login. For a home near Aimwell, enter a street address, an owner's name or a parcel number, and the viewer zooms to the match. For a tract near Dayton, the parcel card normally shows the owner of record, assessed acreage, a parcel ID and in many cases the last transfer.
Neighboring parcel maps
The county meets Choctaw County, Clarke County, Dallas County, Greene County, and Hale County, all with their own assessor records, at least around Aimwell. Acreage along the edge near Sweet Water can be split in two county records, so open the neighboring map before you assume the acreage. With a lot near Nanafalia, our state page lists every neighboring county map for Alabama.
A word on accuracy
Acreage on the record is an assessed number; just a licensed surveyor establishes the real boundary on land around Aimwell. For a tract near Putnam, owner names and values update on a schedule, so a deed recorded last month might lag behind.
Legal descriptions in Alabama
Alabama follows the Public Land Survey System, so deeds around Sweet Water reference sections and townships. Each section is nominally a mile square, about 640 acres, with 36 sections to a township, though corrections make some sections near Alfalfa odd-sized. Write down the legal description for the tract near Providence when you talk to a surveyor.
Zones on the Marengo County flood zone map
Out toward Nanafalia, zones beginning with A or V mark the Special Flood Hazard Area, which FEMA defines as a 1% annual chance of flooding. In and around Demopolis, a shaded X area is moderate risk, between the 1% and 0.2% annual chance floods; plain X, or C on older maps, means minimal mapped risk.
A short flood checklist
For a home near Beaver Creek, ask the seller about past flood claims before closing; an insurance quote early keeps the budget honest.
Water near Providence
Low-lying fields near Alfalfa may not have detailed mapping, so ask neighbors about past flooding. Marshy spots near Demopolis can limit building too; check the National Wetlands Inventory mapper for a first look.
Matching the zone to the lot lines
FEMA's map shows zones but not ownership, so open the AlabamaGIS / Flagship GIS - Marengo County Revenue Commission public GIS next to see exactly which lot near Beaver Creek you're looking at.
Places you'll see on the map
Linden holds the county offices, home to the main records offices. You'll also find Demopolis, Dayton, Faunsdale, and Myrtlewood, each with its own cluster of lots. About 18,684 people call Marengo County home (Census estimate, 2023) across roughly 977 square miles. The county was formed in 1818, and some chains of title near Dayton are long.
Field tips
Most viewers work in a phone browser, which helps when you're standing on land near Myrtlewood, though signal can drop in rural spots. A printout of the tract near Aimwell keeps working without signal.
Where the recorded documents are
The map is an index, not the title: deeds, plats and easements covering ground around Alfalfa are kept by the Judge of Probate (probate office). Long-held tracts near Dayton may go back through a long string of deeds, and a title company earns its fee if money is changing hands.
Insurance, lenders and building
For a structure inside an A or V zone and the loan is federally backed or regulated, flood insurance is generally required where the community participates in the National Flood Insurance Program, whether the land is near Providence or elsewhere in the county. Building or adding on near Linden in a mapped zone often needs a floodplain permit; ask the local floodplain administrator before you plan.

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.
