Water issues are likely to be more of a problem as our area grows. Related is the changing topography of our area and this article discusses potential changes to the flood map as a result.

The next most vulnerable aquifer is a tie between the Edwards and the Gulf Coast, but the Gulf Coast is different. In April 2026, the Gulf Coast Aquifer—which sits beneath Houston—is the epicenter of a geological crisis. Unlike the Ogallala, which is simply running dry, the Gulf Coast region is physically collapsing into the space where water used to be. This phenomenon is called subsidence, and as of 2026, Houston is the fastest-sinking major city in the United States.

The harm being done to the Gulf Coast Aquifer in 2026 is often described as a "slow-motion collapse." Unlike a river that can be refilled by a good rainstorm, the damage here is structural, chemical, and, in many cases, permanent. To understand how this aquifer is being harmed, we have to look at the three main ways humans and nature are "breaking" it.

Imagine the aquifer as a giant, underground layer of sand mixed with wet clay. When they pump out too much water, the weight of the cities on top (like Houston, Katy, and The Woodlands) becomes too heavy for the empty spaces to handle. The layers of clay, which were once held up by water pressure, collapse and pack tightly together. As a result, the land above actually sinks. In 2026, parts of West Houston and Katy are sinking by more than an inch every year!

Once that clay is crushed, it can never hold water again. Even if we stopped pumping today, that section of the aquifer has lost its "storage capacity" forever. It’s like squeezing a sponge so hard that it turns into a solid brick.

Because this aquifer sits right next to the Gulf of Mexico, there is a constant "tug-of-war" between the fresh water in the ground and the salt water in the ocean.
Normally, the fresh water in the aquifer is under enough pressure to push back against the ocean, keeping the salt water at the coast. But as they pump out the fresh water for homes and industry, that "push" disappears. The salt water from the Gulf is then sucked inland like a vacuum.

In coastal counties, drinking wells are becoming "brackish" (salty). Once salt water enters a freshwater well, it’s ruined for drinking and farming unless you spend millions of dollars on a desalination plant to clean it.

In 2026, the surface of the land is just as much of a problem as the pumping below. Aquifers need rain to soak through the dirt to "recharge." But in the Houston-Galveston area, thousands of square miles are covered in concrete, asphalt, and rooftops. Instead of soaking into the ground to refill the aquifer, the rain hits the pavement and immediately runs into bayous and out to the Gulf. So, we are taking more water out than ever before (to support millions of new residents), while simultaneously "paving over" the only way the aquifer has to refill itself.

The "center" of the sinking has shifted. In the 1970s, the sinking was worst in Baytown and Pasadena. Today, because of massive suburban sprawl, the "hole" has moved to the booming suburbs.

The Katy/Fulshear Corridor is currently the most vulnerable area. Some spots near Katy are sinking over 1 inch per year. The Woodlands and Spring continue to see significant rates of subsidence as thousands of new homes rely on groundwater. Jersey Village is historically one of the hardest-hit areas. This neighborhood has sunk nearly 10 feet since the 1940s, making it a permanent "bowl" that traps floodwaters during even moderate rainstorms.

To stop the sinking, the Harris-Galveston Subsidence District (HGSD) has mandated a massive shift. At the beginning of 2026, they are in the middle of a historic transition. Most water utilities in the region were required to convert at least 60% of their total water demand to "surface water" (water from lakes like Lake Houston or Lake Conroe) rather than groundwater. And the mandate moves to 80% conversion by 2035. This is why water bills in Houston have skyrocketed. Building the "Big Pipe" infrastructure to move lake water to suburbs like Katy costs billions of dollars.

The biggest danger in 2026 isn't the city disappearing under the ocean; it's that the "sinking" has changed the drainage. Because the land is no longer sloped the way nature intended, water can't flow to the Gulf. It pools in the newly formed "low spots" in the suburbs. This means that a storm that wouldn't have flooded a house in 1990 is now a "50-year flood" event for a family in 2026. As a result, the sinking in Houston is affecting insurance rates and "flood zone" maps.

A Higher Level of Foundation Evaluation

In addition to our past foundation evaluation offering, Professional Engineering Inspections is offering a higher level of foundation evaluation that includes elevations and deflection criteria. We have been offering the option of a higher level of foundation evaluation for a while now; although, we have not really advertised it. In the past our foundation inspections were completed using a spirit level as the measurement tool when evaluating the levelness of the structure supported by the foundation we were inspecting. ...
