Selling Land in a Flood Zone in McLennan County: What Owners Should Know

By Stonepath Land · November 3, 2026

Maybe you found out your McLennan County land is in a flood zone when you tried to sell it. Maybe a buyer backed out, or a lender asked about flood insurance. Either way, a lot of owners assume floodplain land can’t be sold.

It can. A flood zone changes who will buy the land and what they’ll pay, but it doesn’t make the land worthless. This guide explains how to check your parcel, what buyers look at, and how to sell.

Where the Floodplain Is in McLennan County

According to McLennan County’s floodplain information, parts of the county are in FEMA’s 100-year floodplain, mainly:

• Along the Brazos River, which fans out across low areas south and east of Waco
• Along the North, Middle, and South Bosque rivers and their creeks

Lake Waco, Lake Whitney, and Aquilla Lake help control river flooding. The current FEMA flood maps for the county took effect on December 20, 2019. If you last looked at your parcel before then, the designation may be different now.

Step 1: Check Your Parcel’s Flood Zone

You can look up any parcel yourself:

1. Get the property ID from the McLennan Central Appraisal District at mclennancad.org by searching your name or the property address.
2. Enter the address or location at the FEMA Flood Map Service Center to see which zone applies.
3. For questions about a specific parcel, the McLennan County Engineer’s office (254-757-5028) handles floodplain questions for unincorporated land (Floodplain Information).

It’s common for only part of a tract to be in the mapped floodplain. A 20-acre tract with 4 acres along a creek in the flood zone is a very different property from a lot that’s fully in the floodplain. Find out which one you have.

Step 2: Understand What a Flood Zone Changes for a Buyer

Building and permits

Unincorporated land in McLennan County generally has no county zoning, but building in a mapped floodplain usually means extra permitting and construction requirements. Inside city limits, the city’s own rules apply. Either way, a buyer who plans to build will factor that in.

Septic and wells

Without city sewer, a home needs a septic system (OSSF). In McLennan County, the Waco-McLennan County Public Health District permits every system regardless of acreage (OSSF program). Low, wet ground can make septic design harder. Rural water usually comes from one of the many water supply corporations in the county or from a private well. Wells are regulated by the Southern Trinity Groundwater Conservation District.

Dividing the land

If a buyer wants to split the tract, dividing land in the county usually requires a plat under the county’s subdivision regulations, unless the County Engineer’s office signs off on an exemption affidavit. Under those regulations, the minimum lot size is 5,000 sq ft with sewer and 1/2 acre without sewer, subject to septic rules. Floodplain acreage can limit how many usable lots a tract will produce.

Financing and insurance

Lenders often require flood insurance on structures in mapped flood zones, and that can narrow the pool of financed buyers. Cash buyers aren’t held to a lender’s requirements.

Step 3: Know Who Buys Floodplain Land

Floodplain land still has uses, and some buyers specifically look for it:

• Neighbors who want extra acreage, a buffer, or more pasture
• Recreational buyers looking for hunting or riverfront land they don’t plan to build on
• Agricultural users who want grazing or hay ground
• Direct land buyers who price the flood zone into a cash offer and handle the research themselves

A traditional listing can work, especially for a tract that’s only partly in the floodplain and has good road frontage. Expect more buyer questions and possibly more time on the market.

Step 4: Price It Honestly

The flood zone is public information, and any serious buyer will look it up. Being upfront about it builds trust and keeps deals from falling apart late. When you set your expectations, think about:

• How much of the parcel is in the floodplain versus above it
• Road access and frontage
• Whether water and electricity are available nearby

A Note on Title, Disclosures, and Taxes

What you have to disclose when you sell, and how a sale affects your taxes, depends on your situation. Talk to a title company or attorney before you sign anything. This article isn’t legal or tax advice.

How Stonepath Land Handles Flood Zone Land

Stonepath Land LLC buys vacant land directly in McLennan County, including Waco, Hewitt, Woodway, Robinson, Lorena, McGregor, Mart, and West, and that includes land in a flood zone. We research location, access, utilities, flood zone, and taxes using McLennan Central Appraisal District data, public records, and FEMA maps. Then we send you a written offer that states the price, the closing timeline, and how closing costs are handled. Floodplain land can still sell. We just factor it in, and we’ll tell you how.

You don’t need to clear, mow, or survey the land first. A licensed title company or attorney handles the closing, and most documents can be e-signed or signed with a mobile notary. Nothing is binding until both sides sign a written purchase agreement.
