We'll cover finding a Limestone County address on FEMA's map, what Zone A, AE and X mean, how the county viewer fits in, and what to do if the map looks wrong.
How to check the Limestone County flood zone map
Start at the FEMA Flood Map Service Center and enter the property address in Mexia or anywhere else in the county. Download the FIRM panel FEMA lists as effective for that part of Limestone County. For an interactive view of the county, FEMA's National Flood Hazard Layer viewer draws the zones over aerial imagery and reports the zone wherever you click near Mexia. Switch to the Texas county CAD map and track down the same property near Coolidge. If the Limestone County viewer has a floodplain layer, treat it as a convenience copy and confirm on FEMA's map.
Step one: the free Limestone County viewer
Limestone County publishes its parcels on the Texas county CAD map, which runs on the ProdigyCAD maps portal, free to use for a lot in Mexia or a property near Mart. Rural accounts near Mart list an abstract in the legal description; copy it with the county property ID. Our Limestone County, TX page keeps the official link and the maps next door to Mart in one place.
High, moderate and minimal risk in Limestone County
For a lot in Mexia, the label matters more than the color: A and V zones are Special Flood Hazard Areas, meaning FEMA estimates a 1-percent annual chance of flooding. Zone AE near Coolidge means FEMA published a base flood elevation; plain Zone A means no detailed elevation was studied. Land near Coolidge in shaded X (Zone B on older maps) falls between the base flood and the 500-year flood. Unshaded X (or C) on the Limestone County panel means minimal risk.
The lay of the land around Groesbeck
Unincorporated communities in the county, including Ben Hur, Buffalo Mop, and Forest Glade, show up as small groups of parcels along the roads. Limestone County had an estimated 22,250 people in 2023 (Census Bureau), spread across about 905 square miles. Beyond the town lots in Tehuacana, expect big rural parcels across the county. Limestone County was organized in 1846, so deeds for older farms near Kosse can run back a long way.
Unmapped creeks in Limestone County
A low spot on a Limestone County tract outside any mapped zone, so treat an unmapped channel as a reason to ask questions, not proof the ground stays dry.

What a flood zone means for a Limestone County buyer
The zone lists up again when a loan on a house near Coolidge is underwritten. Where a building in Mexia is mapped in a high-risk zone and is financed by a regulated or federally insured lender, flood insurance is mandatory under the Flood Disaster Protection Act, wherever the community joins the NFIP. For a Limestone County home in shaded or unshaded X, insurance is a choice, not a mandate, although a lender in Texas can still ask for it. If a building near Coolidge sits above the flood line, FEMA's LOMA process allows a review, most frequently backed by an elevation certificate from a surveyor who works in the county. Placing fill on low ground near Mexia frequently requires a permit and an elevation check, and the building office serving Coolidge explains the steps.
Deeds and plats behind the Limestone County map
For land near Mexia, the deed itself lives in the county recording office, and the map is an index to it. For a property near Mart, the appraised value is set by the county appraisal district, which Texas law keeps separate from county government. A deed book and page or instrument number on the county record is the quickest route to order the document for a lot in Mexia.
