Building 7,000 Homes Here Would Accelerate Subsidence

4/19/25 – Ryko, a development company, has announced plans to build 7,000 new homes in an environmentally sensitive, flood-prone area immediately west of Kingwood. Moreover, the area already experiences the highest subsidence in the north Houston region.

Residents in the area currently use groundwater. Assuming an average household size of 2.5 people, Ryko would add 17,500 new residents to the area. That could accelerate declines in groundwater levels and increase subsidence.

Reviewing the Subsidence District’s latest annual report revealed that the issue at this one reporting station is part of a larger problem. And the problem is very bad in southern Montgomery County.

Impacts of Subsidence

I have been posting about the issue for five-plus years. Subsidence happens too slowly to notice in most cases. But over time, it can be very disruptive:

  • Excessive groundwater withdrawals can create bowls in the landscape that alter the gradient of rivers and streams. That can increase local flooding. For instance, when land at the county line sinks faster than land at the Lake Houston Dam, it tilts the lake toward the county line.
  • Projected subsidence rates upstream could erase your freeboard factor (the height at which your home was built above the 100-year floodplain). That would increase your flood risk.
  • Subsidence can also crack pipelines, storm sewers, and pavement.
  • Uneven settling can cause your doors and windows to stick; crack foundations; split wallboard; and break tile.
  • Near Galveston Bay, a whole subdivision even sank beneath the waves.
  • Subsidence can also trigger long-dormant geologic faults.

For more examples of the impacts of subsidence in the north Houston area, visit StopOurSinking.com, a site developed by a Woodlands resident. There, subsidence has triggered faults and flooded multi-million-dollar homes through the “bowl effect.”

High Cost of a Little Flooding

Getting even an inch of water in your home can be very costly. According to FEMA, just 1 inch of floodwater in an average 2,000 square foot home can cost $10,000 to $20,000 to repair.

Higher-end finishes, such as wood floors, built-in cabinetry, granite, etc., can push those estimates past $25,000.

Why is one inch so expensive?

  • Flooring usually needs to be completely replaced (carpet, wood, sometimes even tile if the water gets underneath).
  • Baseboards and lower drywall (often up to 2 feet) usually must be cut out and replaced.
  • Insulation in walls may need replacing if water wicks up.
  • Cabinet bases and interior doors are often ruined.
  • Appliances like washers, dryers, and even low-mounted electrical outlets might be affected.
  • Mold prevention requires fast and sometimes professional drying and remediation.

In homes larger than 2,000 square feet, the cost would go up proportionately. For instance, FEMA estimates repair costs for a 3,000 square foot home to be 50% greater – in the $15,000 – $30,000+ range.

Disasters/accidents are rarely caused by one thing. They usually result from a combination of factors eroding margins of safety.

For instance, the risk of a driving accident increases when you’re tired, it’s dark and the pavement is wet. That’s why it’s important to pay attention to little things that can degrade your margin of safety. They may not be so little in the next big storm.

Ramsey, Flickinger Discuss Status of Flood Projects

1/16/2025 – Harris County Precinct 3 Commissioner Tom Ramsey, PE, and Distict E Houston City Council Member Fred Flickinger discussed the status of numerous flood projects at a meeting of the Kingwood Area Republican Women today at the Oakhurst Golf Club.

Ramsey addressing Kingwood Area Republican Women’s Club today.

Among the projects they covered were:

  • Taylor Gully Improvements/Woodridge Village Detention
  • Kingwood Diversion Ditch Improvements/Upstream Detention
  • Additional Floodgates for Lake Houston
  • Legal Changes Governing Pre-Release of Water from Lakes
  • Edgewater Park
  • Dredging
  • Medians
  • Flood Tunnels
  • Subsidence

Below are the highlights. They also discussed other issues such as median maintenance, vine control, crime, taxes, government waste, elections and more. But I will focus primarily on infrastructure issues related to flooding – especially Taylor Gully and Woodridge Village, because of pending approvals this month.

Taylor Gully/Woodridge Village

After Perry Homes clearcut approximately 270 acres in Montgomery County, hundreds of Kingwood homes flooded twice in 2019 along Taylor Gully. Taylor Gully runs through the northern part of Kingwood from Kingwood Park High School to White Oak Creek.

Taylor Gully/Woodridge Village

Harris County Flood Control District (HCDFC) began working on mitigation plans in 2021 and presented preliminary recommendations to the community in December, 2022.

The county had high hopes for funding from the Texas General Land Office (GLO) and U.S. Department of Housing and Urban Development (HUD), but those ran into a potential snag. Taylor Gully improvements fit within available HUD funding, but Woodridge Village (the former Perry Homes Property) did not. HCFCD hoped to build more stormwater detention basin capacity on Woodridge to help control Taylor Gully expenses downstream.

Regardless HCFCD pressed forward. They combined the two projects. And according to HCFCD, both now fit with available funding capacity (see “above the line” list on page 2) of the list being presented to Commissioners Court next week on 1/23/25.

The county purchased Woodridge Village in February 2021. Shortly thereafter, HCFCD began an excavation and removal (E&R) contract to get a “head start” on the basins. Indeed, the head start brought the total stormwater detention on the site almost to Atlas-14 standards.

However, HCFCD was forced to terminate the E&R contract before the basins could be completed. That was to comply with HUD requirements while HUD considered the grant application.

This is potentially great news for the people who live in Sherwood Trails, Elm Grove, Mills Branch and Woodstream.

Watch commissioner’s court closely next Thursday. The Kingwood area drainage study named this project as one of the two most important in Kingwood.

Kingwood Diversion Ditch and Upstream Detention

The Kingwood Diversion Ditch was the other of the two most important projects. The Diversion Ditch takes floodwaters out of Bens Branch, which runs diagonally through the center of Kingwood from St. Martha Catholic Church to River Grove Park.

Improving the Diversion Ditch would reduce flood risk for hundreds of homes and apartments, Kingwood High School, Town Center, and Kings Harbor. Both Bens Branch and the Diversion Ditch currently have a two-year level of service. That means they have a 50% chance of coming out of their banks in any given year.

The District started preliminary engineering in mid-2021. HCFCD will finally present that report to Commissioners Court on February 6, 2025.

Ramsey estimated today that the project could cost $60 million. However, he also indicated that U.S. Congressman Dan Crenshaw “got us enough money so we can do the final engineering.”

Eric Heppen, Precinct 3 engineer, later stated that once Commissioners Court approves the preliminary report, it will be made public.

Flickinger emphasized that he is talking with Montgomery County, trying to get them to retain more of their floodwaters. He raised concerns about a new 200,000 sq. ft. convention center planned for US59 at Valley Ranch. “That will generate a lot of runoff that could come down to us, unless we work together to find a way to hold that water up there.”

Houston City Council Member Fred Flickinger at same meeting.

Additional Floodgates for Lake Houston

Shortly after Harvey, many people pinned their flood-mitigation hopes on additional floodgates for the Lake Houston dam. The idea: to lower the lake faster when it becomes certain that a storm will flood the area. The existing gates have 1/15th the capacity of Lake Conroe’s. So Lake Houston must start releasing far earlier in advance of storms than Lake Conroe. And by the time Lake Houston is lowered, storms can veer away, wasting valuable water.

So Conroe tends to hold its water back until it is absolutely certain. At that point, it has no other choice than to release water at high rates that flood people downstream.

Being able to lower Lake Houston faster would let Lake Conroe release earlier and slower, smoothing out flood peaks downstream.

Ramsey estimated the cost of 11 new floodgates that could release 80,000 cubic feet per second at $150 million. He said the final engineering should be completed this year. He also said that bidding and construction could start in 2026.

Legal Changes Governing Pre-Release of Water

Flickinger addressed a related legal issue. State law limits the release of water from lakes; it must be only for defined beneficial uses and flood control is not one of them.

So, Flickinger is working with State Rep. Charles Cunningham to change that and increase the limit. “Bottom line,” he said, “is that we need to release more water sooner rather than holding it back until we’re adding to the crest of the flood.”

Flickinger is also working with the San Jacinto River Authority on these changes.

Edgewater Park

After Harvey, the County acquired land on the northeast corner of the West Fork and US59, which will turn into Edgewater Park. It will also connect the Houston Parks Board’s West Fork Greenway with the Spring Creek Nature Trail. Ramsey said the plans will be made public very soon. After the meeting, Precinct 3 engineer Eric Heppen confirmed the plans were 99% complete.

Ramsey said, “Soon, you’ll be able to go from Kingwood to Tomball and not cross a road.” That should be a tremendous draw for hikers and bikers and the entire area.

Dredging

Flickinger discussed two aspects of dredging not covered in last night’s post. First, he is seeking additional funding to continue the current program while the dredge is on the lake. Second, he feels opportunities exist to increase efficiency.

I asked what he meant by that. FEMA restrictions on the funds currently being used limit the dredging to “pre-Harvey” conditions. That means, Callan Marine, the contractor, must dredge to different depths to match the exact bottom profile that existed before Harvey. And that requires repositioning the dredge more than if you were just dredging to a uniform depth across wide areas.

The search for additional funding has led Flickinger to the City, the Coastal Water Authority (CWA) and former State Representative Dan Huberty. Huberty was appointed to the board of CWA last last year by Houston Mayor John Whitmire.

Medians

Several people from the audience questioned Flickinger about the medians along Kingwood Drive. He touted the success of his first Median Madness event in November 2024 and announced another on February 22, 2025. Mark your calendar now.

More than 50 volunteers participated in the last vine-cutting extravaganza. He hopes for many more volunteers this time.

Flood Tunnels

The county is getting ready to launch the next phase of its flood tunnel study. Ramsey emphasized that there isn’t enough room in Harris County to poke enough holes in the ground to solve all of our flooding problems. He sees tunnels that carry floodwater from strategic locations as essential parts of the solution.

Eric Heppen, Ramsey’s engineer said that by burying the 40 foot tunnels 80 feet underground, you can double the conveyance in some watersheds, sidestep environmental issues, and avoid having to condemn property.

But many issues have yet to be worked out. For instance, will tunnels be constructed to relieve 2-year, 5-year, 10-year, 25-year or 50-year flooding? More to follow when details become available.

Subsidence

Harris County estimates the area east of Lake Houston will grow by 18,000 homes in the next 10 years. But there currently are no plans to provide them with surface water. So, they will pump groundwater. That means subsidence. And subsidence means flooding, according to Ramsey. He pointed to Conroe as an example. The City’s groundwater pumping has caused subsidence as far south as Harris County.

Subsidence District to Study Alternative Water Supply for NE Harris County

11/21/24 – Last week, the Harris-Galveston Subsidence District published a request for qualifications (RFQ) for consultants interested in conducting an alternative water supply feasibility study for Northeast Harris County.

Mike Turco, the District’s general manager, said he is specifically focused on the area east of Lake Houston, which is experiencing tremendous growth. The completion of the Grand Parkway has triggered much of that growth. And with it will come increased water demand, which has the potential to trigger subsidence.

“Alternative Water” Reduces Effects of Subsidence

The District defines “an alternative water supply” as a source that does not trigger subsidence. That most often means a source other than groundwater. Subsidence frequently results from excessive groundwater extraction. That can cause compaction of the earth and a whole range of consequences.

Such compaction caused an entire Baytown subdivision to sink into Galveston Bay.

Subsidence can also cause bowls in the landscape that trap water and increase flood risk Subsidence can even change the gradient of streams, slowing water down and backing it up.

An SMU study found that subsidence can cause faulting and damage structures such as homes, roads, pipelines, storm sewers, sanitary sewers and more.

Differential subsidence can create another set of problems altogether. For instance, the rate of subsidence at the Harris/Montgomery county line is much greater than the rate at the Lake Houston Dam.

That has the potential to tilt the lake toward its headwaters. And that could reduce the freeboard factor (feet above flood level) for homes in northern Harris County.

But alternative water sources can reduce all those impacts.

Examples of Alternative Water

In this region, surface water, i.e., from Lake Houston, is the most common “alternative water source,” according to the District’s definition. Lake Houston provides water for more than 2 million people without causing any subsidence.

alternative water source
One example of an alternative water source. Lake Houston from Kingwood’s East End Park. By Dr. Charles Campbell.

So if we already have the major source of water in the area, why look at other alternatives? The planning horizon for water projects is typically 50 years. The RFQ specifically mentions recommendations to meet demand through 2070.

Given expected population growth during that period, the region may need more than Lake Houston. So it behooves us to look at all available alternatives.

According to Turco, right now, the City is already aggressively expanding water distribution from Lake Houston to areas like Spring, which has experienced some of the worst subsidence in the region – 30.5 centimeters, slightly more than a foot since 2007. See below.

The City is also expanding the Northeast Waster Purification Plant and bringing in water from Lake Livingston via the Luce Bayou Inter-basin Transfer Project. But will it be enough to meet demand 50 years from now?

Other alternative sources could conceivably reduce demands on Lake Houston. They include but are not limited to:

  • Building a new reservoir
  • Constructing pipelines from existing reservoirs
  • Using reclaimed water for specific needs, such as irrigation or agriculture
  • Desalination of Bay water

For More Information

A District spokesperson said they want to look at all options, costs and timing. To review the RFQ, click here.

For the District’s latest annual report on subsidence, see this six-page executive summary, this 47-page presentation, or the 307-page full report with appendices.

Subsidence is widely considered to be irreversible. It’s comforting to know that people are already planning for the welfare of our grandchildren.

Easy Way to Reduce Water Usage, Costs, Subsidence and Flood Risk

The Texas A&M Agrilife Extension Service, working with local government organizations, has developed a free, customized program that might help you reduce water usage, costs, subsidence and flood risk. It’s called the WaterMyYard program.

A large percentage of the water used in urban areas goes to watering lawns. On average, the EPA estimates 30-60% of residential water irrigates lawns. Your percentage may vary depending on your location, distance inland, average temperature, rainfall, size of yard, etc. But in general, 50% is a good average estimate.

Grass is the most watered crop in America. And many of us overwater our lawns, running up water bills needlessly.

How WaterMyYard Program Works

WaterMyYard uses local weather data in participating areas to provide free, weekly watering advice.

The system collects data from an extensive network of weather stations and rain gauges. It then correlates that data with evapotranspiration rates for major grass types; air and soil temperatures; rainfall; wind; and dew points so you can put the precise amount of water on your lawn that it needs to stay healthy.

Example: data for North Houston in the last 7 Days used as basis for calculations.

When you sign up for the service, you answer a few questions about the type of sprinklers you have and the inches per hour they spread on your lawn. Based on measured weather data, the system then sends you customized weekly water advice for your specific lawn and irrigation system.

The system takes the guess work out of knowing when and how much to water.

Texas A&M Agrilife Extension

For instance, it could tell you how much to cut back after a major rain or how much to increase watering during a dry spell.

If you don’t know how much water your system puts out per hour, don’t worry, you can change the amount after you sign up. You can use typical rates for different types of sprinkler systems. Or you can actually measure it by placing cans around your yard during watering cycles.

You can also add sprinkler systems, for instance, if you have one type for your lawn and another for flower beds and shrubs.

Testimonial: Water Usage Cut in Half

One user I know said he was able to cut his water usage by 50%. “I dropped home consumption in half and my lawn is still green and everything’s still fine,” he said. “Most of us just don’t have enough information. When we go into new homes, we just leave the sprinkler settings the way the last guy had them.”

“I really didn’t pay much attention to them,” he continued. “As long as my grass was green, I was good. But a lot of research out there says that we can be more efficient with that. And that’s what the WaterMyYard program does.”

With water rates constantly going up, it’s easy to see how eliminating wasted water, can save you money. But how does lawn watering affect subsidence and how does that affect flood risk?

Connection to Subsidence, Flooding

Large parts of the region still aren’t on surface water; they use groundwater. And if we use groundwater faster than it’s being replaced, we experience subsidence. Places in northwest Harris County sank 50 centimeters (almost 20 inches) between 2000 and 2022.

From presentation to Harris-Galveston Board of Directors on 12/8/2023.

In a flat area like Houston, an inch per year can be significant. One subsidence expert said it can be enough to reduce the gradient of whole watersheds over a decade or two. That means stormwater doesn’t move away as quickly as it once did. So, in large rainfalls, flood peaks build higher faster.

Now consider this. If lawn irrigation accounts for half of residential water use, and if half of lawn irrigation is unnecessary, up to 25% of water we use could have stayed in the ground. And that could significantly reduce subsidence and flood risk while reducing your monthly water bill.

The sooner you act, the more you save. So sign up for WaterMyLawn weekly watering advisories today.

Jace Houston Resigns as SJRA General Manager Under Pressure from Subsidence Deniers

Jace Houston, the San Jacinto River Authority’s (SJRA) General Manager and point person on subsidence issues, resigned yesterday, 5/25/23, to avert a political war with Montgomery County subsidence deniers that could have taken down the entire SJRA board.

Houston had been with the SJRA for 16 years after spending 10 years with the Harris-Galveston Subsidence District. While at the SJRA, the lawyer/engineer helped put together a Groundwater Reduction Plan that included 80 municipalities and municipal utility districts (MUDs) across Montgomery County. He also helped the SJRA construct a surface-water treatment plant on Lake Conroe.

Goals of Effort to Preserve Groundwater

The half-billion dollar plant supplies surface water to the major population centers in Montgomery County, such as Conroe, The Woodlands and Oak Ridge North. Converting the population centers to surface water preserved groundwater for less populated and rural areas where water pipelines become uneconomical.

When the plant came online in 2015, it also virtually neutralized subsidence (see below).

subsidence
When The Woodlands began using more surface water in 2016 after completion of a surface water pipeline, the rate of subsidence virtually leveled off.

The groundwater preservation effort proved effective at eliminating subsidence. It also helped water utilities avoid major costs associated with declining aquifer levels.

What costs? When water levels in wells drop, suppliers must move pumps deeper and use more electricity to pump water to the surface. In extreme cases, utilities may not be able to get water to the surface at all. Then they must drill new wells, often into deeper aquifers at hefty costs.

Declining well levels are especially worrisome in drought years when/where no alternative sources of water are available. Lack of water can limit population and economic growth as well as agricultural production.

However, preserving groundwater came at a cost. All members of the plan paid a fee to help pay for the surface water treatment plant even if they didn’t buy water from it. The need for such a plan became apparent more than 20 years ago, long before Houston joined the SJRA.

Need to Use Less Groundwater Validated by Legislature, But…

The Texas Leglislature validated the need to use less groundwater when it created the Lone Star Groundwater Conservation District (LSGCD) in 2001.

But in recent years, all that was forgotten. The LSGCD board denied subsidence was a problem and advocated unlimited groundwater pumping as a way to lower water costs.

In the meantime, subsidence has returned. So have water well declines.

As you can see below, since the Lone Star Groundwater Conservation District began moving to deregulate groundwater usage, well levels have dropped significantly across the county, setting up a day of reckoning in the future.

A Shot Across the Bow of the Board

Undeterred by these signals, the City of Conroe and the LSGCD board took their fight to the state legislature. They got State Representative Will Metcalf of Conroe to propose an amendment to the SJRA Sunset Review Bill that would replace Jace Houston. The amendment passed and emboldened Metcalf, Conroe and the LSGCD.

The amended bill then went to the Senate Water, Agricultural and Rural Affairs Committee where the Conroe/LSGCD contingent testified again. But Senator Charles Perry, the committee chair, talked his fellow members out of adopting their proposals.

However, during the committee debate, Senator Lois Kolkorst, who represents Magnolia, fired a shot across the bow of the SJRA. She suggested making SJRA board-member terms one year.

That would have been disastrous, according to one seasoned SJRA board member, “It takes a year just to learn the job,” he said.

After defeat of all suggested amendments in Perry’s committee, it didn’t take long for back-channel rumors to mushroom. A whisper campaign suggested that sympathetic senator(s) might offer the Metcalf amendment or a one-year board amendment when the bill came up for a vote on the Senate floor.

Within days, the SJRA called a special board meeting to discuss Houston’s employment. While Houston reportedly had many supporters on the SJRA Board, he ultimately chose to resign and avoid a political battle royal that could have damaged the SJRA.

Board Accepts Houston’s Resignation

An article in Community Impact quoted SJRA Board President Ronald Anderson as saying: “At today’s meeting, the SJRA board of directors received and reluctantly accepted a resignation letter from our general manager, Jace Houston. Jace has served with honor and distinction for almost 16 years and has made the SJRA one of the most respected water agencies in the state of Texas.”

Anderson continued, “Even through these recent circumstances involving the legislature, Jace has once again placed the best interests of our organization and customers above his own, and the board wishes him the best in his future endeavors, which we know will be marked by continued success.”

Houston will remain at the SJRA until June 30th. But even on his way out the door, he seems less concerned about his own future than Montgomery County’s water future.

Impact of LSGCD on Water Future of MoCo and More

When asked about the impact of the LSGCD moves, Houston predicted, “They’re not going to regulate the aquifers. They’re going to allow pumpage to increase significantly.”

Houston added, “A lot of great work has been done to put a program together that allows Montgomery County to be able to afford the future water supplies it needs. And all of that is at risk. This just puts the county’s future at risk. They don’t understand the science. LSGCD is just dead wrong on the science.”

Because aquifers flow toward the coast, depleting groundwater in Montgomery County affects Harris and Galveston communities as well. But Metcalf and the LSGCD board never seemed to consider the impact on neighboring counties even though Metcalf’s district represents only about one thirtieth of the population in the San Jacinto watershed.

Because of differential subsidence, the impact of unlimited groundwater pumping in southern Montgomery County could actually tilt Lake Houston toward the north. That’s because the Kingwood/Porter area would subside more than the Lake Houston Dam by about two feet. And that could put many homes near floodplains into floodplains.

Projected subsidence in the northern Lake Houston Area could be 3.25 feet.
subsidence in Harris County
Meanwhile, projected subsidence at the Lake Houston Dam would only be 1.25 feet.

The US Geological Survey (USGS) should release new, updated models later this year that could affect the rates shown approve (plus or minus).

In the meantime, for anyone who doubts the relationship between water-well declines and subsidence, USGS has published a 432-page scientific report on the subject based on 120 years of data from northeast Texas aquifers.

Houston’s resignation seems to have averted a San Jacinto showdown for now. But some fear this fight isn’t over yet. Stay tuned for the next exciting episode of “As the Swamp Sinks.”

2096 Days since Hurricane Harvey

The thoughts expressed in this post represent opinions on matters of public concern and safety. They are protected by the First Amendment of the US Constitution and the Anti-SLAPP Statute of the Great State of Texas.

Amendment to H.B. 1540 Could Force Changes in SJRA Management

H.B. 1540 passed in the Texas House on Friday, April 28, 2023. The bill concerns recommendations from the Sunset Advisory Commission affecting the board of the SJRA.

However, Representative Will Metcalf from Conroe offered a last-minute amendment from the House floor that would effectively fire Jace Houston, the SJRA’s general manager, who reports to the board. The amendment has the potential to upset the delicate balance between upstream and downstream interests mandated by the Governor after Harvey.

The senate version of the bill does not include Metcalf’s amendment. So, this fight isn’t over yet.

Let me cover the bill, the amendment, and implications in that order.

Key Provisions of H.B. 1540

The House analysis summarizes key provisions of H.B. 1540. It revises provisions governing SJRA. It implements – across-the-board – all Sunset Advisory Commission policy recommendations relating to the following:

  • Gubernatorial designation of the presiding officer of SJRA’s board of directors;
  • Specific grounds for removal of a board member;
  • Board member training;
  • Separation of the board’s policy-making responsibilities and the staff’s management responsibilities;
  • Maintenance of complaint information; and
  • Public testimony at board meetings.

The bill also provides for the transition to the new training requirements for current board members. Significantly, it also adds an additional member to SJRA’s board of directors, decreases the length of a member’s term from six years to four years, and provides for the transition to this new membership and term length.

H.B. 1540 would require at least four of the seven SJRA board members to reside in Montgomery County.

H.B. 1540 requires SJRA’s board of directors to develop and implement a comprehensive policy that provides a structure for public engagement in advance of major actions and projects. The policy must include a clear and detailed description of how SJRA will seek to actively engage stakeholders, including the possible use of the following:

  • Advisory committees;
  • Community panels;
  • Town hall meetings;
  • Surveys;
  • Other strategies on a recurring basis.

General-Manager Amendment

After the bill was voted out of the House Natural Resources Committee, Representative Metcalf offered an amendment on the House floor that surprised Committee Chair Tracy King.

Rep. Will Metcalf
Rep. Metcalf from Conroe

The terse amendment requires that the board appoint a new SJRA General Manager within 30 days who hasn’t been employed by the SJRA as general manager within the last six months. It’s a dagger in Jace Houston’s back.

Chairman King spoke against the amendment, but in the end voted for the bill. King stated that the amendment tried to usurp the Governor’s authority. He pointed out that the Governor appoints the board and that the board hires the general manager. The legislature should not get in the middle of that, he said.

Why Try to Fire Houston?

During Metcalf’s testimony, he complained bitterly about SJRA’s:

  • Water rates
  • Groundwater reduction plan
  • Water treatment plant
  • Insistence that the City of Conroe uphold its SJRA contract
  • Seasonal-lowering policy of Lake Conroe that protects downstream residents
  • Battles with the Lonestar Groundwater Conservation District over subsidence.

As SJRA General Manager, Jace Houston has played a prominent role in all these controversies.

Let’s Go to the Videotape!

If you want to watch how this debate unfolded, here’s a link to the Texas House proceedings on H.B. 1540 and Metcalf’s amendment.

  • Discussion starts around 2:27:15.
  • Rep. Metcalf introduces his amendment at 2:28:20.
  • Chairman King raises a point of order against the amendment at 2:29:10. He says the amendment is not germane to the subject of the bill. Then there’s a long break in the action while they confer on the point of order.
  • At 2:41:10, discussion resumes. King has withdrawn his point of order and rises to speak in opposition to the amendment. Metcalf follows him. Then they hold a vote. The bill passes with the amendment.
  • At 2:47:50, discussion moves to the next bill.

Amended Bill Overwhelmingly Passes, But…

The House bill passed with 145 Yeas, 2 Nays, and 1 Present but not voting. However…

Four days earlier, on 4/24/23, the Senate passed S.B. 2586, an identical companion bill (minus the Metcalf amendment). It’s now in King’s House Natural Resources Committee.

That means the bill could go to a conference committee to iron out the difference and find a compromise. Then the House, Senate or both will have to vote on it again. Exactly one month remains in this session.

In the meantime, you can bet heavy-duty politicking will happen in Austin.

What’s Next? 

Does the Senate have the appetite to engage in a local water war this late in session? 

Will Senator Brandon Creighton whose district now includes Lake Conroe intervene?

Will Jace Houston fight to stay? Or will he throw in the towel? 

Is Metcalf trying to scare the SJRA into concessions?

Will the Governor weigh in? Stay tuned.  

San Jacinto River Basin

The San Jacinto river basin encompasses more than 5,000 square miles and 6.4 million people in 11 counties.

Yet Representative Metcalf seems concerned with only a small portion of them. Montgomery County has a tenth of that population in only a 1,000 square miles. And Metcalf represents only part of Montgomery County and a third of its population. Yet Mr. Metcalf seems to want to manage the SJRA for the benefit of 1 out of every 30 people in the watershed.

Last session, he introduced a bill that would have prohibited any downstream representation on the SJRA board. Luckily, it failed.

The San Jacinto river basin is much larger than Conroe, Metcalf, and his district.

That point seems to have eluded everyone who voted for Metcalf’s amendment. I hope calmer minds prevail.

Had this vote happened after Harvey, I think few would have defended the SJRA or Jace Houston. But since then, I have seen a concerted effort to find balance between upstream and downstream interests, as the Governor directed.

Metcalf’s amendment could potentially tilt the balance back upstream, the way it was before Harvey. We just don’t know. The uncertainty worries me. Will we be saying goodbye to lake lowering and hello to more subsidence?

MoCo District Judge Slams Door on Subsidence Deniers

In a devastating ruling for Quadvest, L.P., and Woodland Oaks Utility, L.P., John Delaney, visiting judge in the 284th District Court in Montgomery County, rejected their pre-trial arguments and granted a summary judgment that validated the San Jacinto River Authority’s Groundwater Reduction Plan (GRP) contract. Both Quadvest and Woodland Oaks have been subsidence deniers in the past.

The only question now is whether the SJRA’s water rates are fair. However, Jace Houston, SJRA general manager, points out that SJRA makes no profit from selling water and that the defendants have cost the river authority more than $12.7 million by withholding contractual payments due under the GRP contract.

Other signers of the contract who did not contest it have had to pick up the slack for Quadvest and Woodland Oaks, placing an unfair burden on them. Both companies are private companies that pump groundwater in Montgomery County.

Excessive groundwater production in Montgomery County has been linked to subsidence and flooding there and in Harris County.

Content of Rulings

In a terse, one paragraph order, the judge ruled that the arguments, pleadings, papers and evidence of Quadvest and Woodland Oaks should be denied under applicable law. Delaney signed the order on December 16th, 2022.

In a separate order on the same day, Judge Delaney ruled on the defendant’s defenses. Quadvest and Woodland Oaks claimed:

  • Lack of consideration
  • Failure of consideration
  • Fraud
  • Illegality
  • Mutual Mistake

In the second order, the Judge simply stated that those defenses were DENIED.

The order concluded, “The Court has determined as a matter of law that “SJRA’s GRP Contracts are incontestable, valid, and enforceable according to their terms.”

Why Contract is Incontestable

State law makes it clear that when a contract is signed that relates to a bond offering and which has been approved by the State Attorney General, the contract is incontestable. In this case, the SJRA issued $550 million of bonds and the Texas Attorney General approved the contract.

SJRA used the bonds to build its surface water treatment plant on Lake Conroe and a distribution system. The distribution system also required acquiring rights of way.

“Consideration” received by the 80 entities signing the contract included:

Quadvest and Woodland Oaks claimed they received no consideration because LSGCD had since changed its rules after the current Board became elected in 2018 – thanks in large part to major contributions by Quadvest.

The goal of reducing groundwater usage was an attempt by suppliers in the region to reduce subsidence.

Since 2020, Quadvest and Woodlands Oaks have refused to pay the rate due under the contract, but have continued to charge their customers as if they are abiding by the contracted amount. 

Jace Houston, SJRA general manager, points out that the defendants had 30 other groundwater reduction plans they could have joined back in 2010 (when the contract went into effect) if they felt they weren’t getting fair consideration.

Subsidence reduced, then leveled off for several years after the contract. However, it is now accelerating again thanks to virtually unlimited groundwater pumping by Quadvest and others.

Second Lawsuit Still Winding its Way Through Courts

Although the ruling applied only to Quadvest and Woodland Oaks, it also has implications for two other entities, the Cities of Magnolia and Conroe.

Both signed the SJRA GRP contract. And both withhold payments. Magnolia is currently $800,000 in arrears and Conroe owes $15.8 million. With Quadvest and Woodland Oaks, that brings the total owed to the SJRA up to $29.3 million.

However, Magnolia and Conroe are not making the same claims as the two private entities. They claim “governmental immunity.”

Interestingly, the attorney general is worried about such claims BETWEEN governmental entities. If for some reason a judge allows the claim, a high percentage of regional water supply contracts in the State of Texas could become unenforceable, according to Mr. Houston. As a result, the Texas Water Development Board has stopped making loans and grants to entities in breach of such contracts. Interestingly, of the 80 parties signing the SJRA GRP contract, virtually half are governmental entities of some sort.

Next Steps

“Quadvest and others have tried for years to cloud the issues and confuse the public about the GRP Contracts, and today all of that has been put to rest,” said Mr. Houston.  “Decisions up to this point have been on pre-trial matters such as jurisdiction and venue. We are pleased to have a ruling on the merits that declares the GRP contracts valid and incontestable in any court.”

“Any further proceedings in Montgomery County should only be to verify that the rates are reasonable,” said Houston. “We look forward to presenting to the court how SJRA takes great care to prepare a very conservative and reasonable budget, and charge rates that are ultimately voted on by our customers.”

Judge Delaney’s rulings, though not directly on the subject of subsidence, have the potential to impact it. Without a financial incentive by companies like Quadvest to deny subsidence, perhaps the LSGCD board will quit trying to deny it, too.

New UH Study Finds Subsidence Increasing in Houston Suburbs

A hot-spot analysis of subsidence in the Houston metro area during the period from 2016 to 2020 revealed total subsidence of up to 9 centimeters in some areas. Rates of subsidence approached 2 cm per year. (Two centimeters equals 0.8 inches. Nine centimeters = 3.54 inches.)

The scientific study, named “Surface Deformation Analysis of the Houston Area Using Time Series Interferometry and Emerging Hot Spot Analysis” appeared in a scientific journal called Remote Sensing. Authors included Shuhab D. Khan, Otto C. A. Gadea, Alyssa Tello Alvarado and Osman A. Tirmizi from the Department of Earth and Atmospheric Sciences at the University of Houston.

Correlating InSAR Data with Well Data

The authors correlated observations of surface deformation using interferometric synthetic aperture radar (InSAR) data with an analysis of 71,000 water and and 5,000 oil-and-gas wells in the Houston area. They collected the InSAR data over 5 years and the well data going back 31 years.

USGS calls InSAR an effective way to measure changes in land-surface altitude. The images are compiled by using radar signals with a very high degree of resolution bounced off Earth from orbiting satellites. By measuring the time for the signals to travel to earth and back, researches can measure altitude. And by superimposing images taken at different times, researchers can measure changes in altitude over time.

Documenting Link between Subsidence and Groundwater Pumping

Khan and his team sought to determine how much groundwater pumping contributed to subsidence (sinking ground). They performed the same analysis for oil and gas pumping.

The researchers found the greatest subsidence – which had not been previously reported – in some of the region’s fast-growing suburbs – Katy, Spring, The Woodlands, Fresno and Mont Belvieu. They identified groundwater pumping as the primary cause in the first four, and oil and gas pumping as the primary cause in Mont Belvieu.

Otto Gadea, a graduate student from Khan’s team is quoted in Phys.org as saying, “We determined for the suburbs that excessive groundwater extraction appears to be the primary driver of subsidence.”

Population Growth Drives Groundwater Pumping

With population growth, groundwater extraction has become more prevalent in the Houston area. But subsidence is no longer substantial in areas that regulate it through entities such as the Harris-Galveston Subsidence District.

The Appearance of Regulation as Cover for Private Interests

Other counties have set up entities to regulate ground water withdrawal, such as the Lone Star Groundwater Conservation District (LSGCD) in Montgomery County. However, the elected board chose not to include a subsidence limit in its desired future conditions. Many of the board members were backed by money from Quadvest, the area’s largest private groundwater pumper.

Website’s such as StopOurSinking.com have long linked excessive groundwater pumping in Montgomery County with a host of issues ranging from subsidence, flooding, pavement breaks, and foundation shifting to pipeline problems. However, the LSGCD Board has cherry-picked scientific evidence that supports unlimited groundwater pumping.

This latest study by the UH team will make that harder. It validates many of the claims StopOurSinking has made for years. Khan’s team even concluded that subsidence may even cause fault movement in the area.

Link to Fault Movement, Too

“If current ground pumping trends continue, faults in Katy and The Woodlands will likely become reactivated and increase in activity over time,” the authors write. No seismic activity is reported along these faults yet they say. They believe the movement is happening by “aseismic creep.” However, Khan and his team found evidence of fault activity in “damages to roads, buildings and other infrastructure in the vicinity of these faults. Displacement along some is measured by up to 3 cm/year.”

August Flood Digest: Brief Summaries of Nine Items in the News

Here’s a short digest of nine flood-related items in the news this month.

Fifth Anniversary of Harvey

This month marks the fifth anniversary of Hurricane Harvey. It’s hard to pinpoint an exact day for Harvey. The system moved off of Africa on August 13, 2017. It became a tropical storm on the 17th; moved into the Gulf on the 22nd; became a Cat 4 hurricane; and made landfall at Port Aransas on the 25th. The outer bands reached Harris County on the 26th.

Harvey dumped heavy rain over Houston for four days. It started moving back offshore on the 29th and 30th. Ninety percent of the river forecast points in southeast Texas reached flood stage; forty-six percent reached new record levels. Harvey dumped more rain than any storm in the history of North America. For more information, see the Hurricane Harvey tab on the Reports Page.

New SJRA Director From Lake Conroe

Most flooding in the Lake Houston Area during Harvey happened after the SJRA started releasing 79,000 cubic feet per second (CFS) from Lake Conroe to save homes there. Many Lake-Houston-Area residents blamed the absence of downstream representation on the SJRA board for what they saw as disregard for their property.

After touring the extensive damage by helicopter, Governor Abbott appointed two Lake-Houston-Area residents (Kaaren Cambio and Mark Micheletti) to the seven-person board. Cambio later resigned to avoid a conflict of interest when she joined Congressman Dan Crenshaw’s staff. Last month, the Governor appointed a Lake Conroe resident to fill her vacancy, Stephanie Johnson. That now leaves Micheletti as the lone downstream representative.

Lone Star Groundwater Conservation District Elections

Sometimes it seems that the main requirements for membership on the LSGCD board are half a brain, a willingness to kiss Simon Sequiera’s ring and indifference to science. Sequiera owns Quadvest, the largest private groundwater pumping company in Montgomery County. And excessive groundwater pumping in MoCo has been linked to subsidence and flooding. But concerned citizens will have a chance to take back the LSGCD board from a slate of directors backed by Sequiera. The deadline for applying is August 22. This page on the LSGCD site is all about the election and how to file if you are interested.

Edgewater Park

Harris County Precinct 3 is trying to jumpstart the development of Edgewater Park at 59 and the San Jacinto West Fork. The county has stated it is hiring a new consultant to re-design the park and that construction could begin 1 to 2 years from now. Quiddity Engineering will get the nod. The project will provide a boat launch, an additional park for the Humble/Kingwood Area, and a connection to the Spring Creek Greenway hike and bike trail. Quiddity’s contract will cover design, engineering, and other pre-construction expenses. Quiddity is the new name for Jones and Carter.

Houston Planning & Development Department News

The Planning and Development Department has a new initiative called Livable Places. The objective: create more housing options for Houstonians. The four options they visualize all increase housing density and impervious cover. I wrote them asking, “Won’t that increase flooding?” In essence, they said, “But it may help other places stay green.” True. But that’s not going to help flooding in the City much. Wasn’t our Drainage Fee designed to provide an incentive to REDUCE impervious cover. Oh well. These are different times. Can we get our drainage fees back now?

Flood Tunnels

Harris County Flood Control District (HCFCD) released Phase 2 of its $30 billion flood tunnel study last month – along with a recommendation to study the recommendations in more detail. The current plan for Phase 3 is to spend the next 4-6 months:

  • Working with the Army Corps to explore possible federal involvement
  • Scoping the Phase 3 study
  • Beginning procurement.

HCFCD hopes to start Phase 3 in early 2023. Said Scott Elmer, P.E. CFM and Assistant Director of Operations for HCFCD, “We expect it to take approximately 3 years to complete.” For the complete Phase 2 study, click here.

GLO HARP Program Deadline

The Texas General Land Office (GLO) announced that applications for its Homeowner Assistance and Reimbursement Program (HARP) will close at 5 p.m. on Aug. 31, 2022. Those include applications for repairs/rebuilds from Tropical Storm Imelda in 2019. To be eligible, you must submit applications by the deadline … unless funding runs out first. So hurry. 

The program includes repair or reconstruction of owner-occupied single-family homes and reimbursement up to $50,000 for certain out-of-pocket expenses incurred for reconstruction, rehabilitation, or mitigation. Repayment of SBA loans is also eligible for reimbursement.

The GLO has $71,604,000 to help residents of Harris, Chambers, Liberty, Jefferson, Montgomery, Orange, and San Jacinto counties. HARP is only available for a primary residences, not second homes. Interested homeowners should visit recovery.texas.gov/harp to apply online or download an application.

Harris County Attrition and Pay Reports

As reported in April, the loss of employees and managers in dozens of Harris County departments has created a brain drain that impacts delivery of county services. On Tuesday, 8/2/22, Commissioners considered two related reports. The first had to do with attrition. The second had to do with pay and benefits.

Commissioners did not discuss the first, but they did discuss the second at length. They also voted unanimously to have the Office of Management and Budget investigate pay disparities. Certain commissioners wanted to apply equity guidelines to low-paid employees and freeze pay for those making more. I didn’t hear the words “Pay for Performance” once during the discussion.

In the end, commissioners recommended having HR create a job architecture, pay structure, and new evaluations that would determine pay increases or freezes. More in future posts.

New Bond Package

Discussion of a new $1.2 billion bond package consumed the last 90 minutes of commissioners court this week. The County Administrator still cannot say where the money is actually needed. Commissioners Adrian Garcia and Rodney Ellis want to apply equity guidelines to this bond. And neither wants to say which projects they would spend the money on. Garcia even threatened in a previous meeting that Republican-leaning precincts would not get ANY of the money if their commissioners voted NO on the bond.

When Hidalgo suggested guidelines for distribution of the money, Garcia stomped out of the meeting. He later reluctantly agreed to a split that would give his precinct and Ellis’ $380 million each while Republican precincts would get only $220 million each.

During the debate, it came out that much of the money from the 2015 bond program still has not been spent. That raised the question, “Why do we need another bond?”

Bragging About Trickery on One Bond While Pitching Another

Also, Commissioner Rodney Ellis publicly bragged that he purposefully didn’t define “equity” in the 2018 flood bond. “It was side language,” he said. “It was not in the language that was on the ballot, but that was the side agreement we agreed to.”

Ellis later said, “Those poor neighborhoods are the ones who have gotten the short end of the process.” But the HCFCD July flood-bond update shows that Halls, Greens, White Oak, Brays and Hunting Bayou Watersheds have received $400 million out of the $1 billion spent to date from the flood bond. Twenty percent of the watersheds are getting 40% of the money. Short end?

I personally don’t plan to vote for another bond until I start seeing some benefit from the last two. Especially when there’s no guarantee how, where or on what the money will be spent. To me, this looks like a $1.2 billion dollar slush fund for Garcia and Ellis.

1803 Days since Hurricane Harvey

Top Stories of 2021 in Review

Below are my personal picks for the top flood-mitigation stories of 2021.

The Fight for Funding

In 2019, Commissioners Court established “equity” guidelines that prioritized projects in Low-to-Moderate Income watersheds. Then this year:

Still no word from HUD on a possible direct allocation of $750 million. We may hear in January.

To help you follow this story, I make quarterly FOIA requests for Harris County Flood Control District spending and post the analyses on a dedicated funding page.

Sand-Mining Best Management Practices

Activists led by the Lake Houston Area Flood Prevention Initiative and the Bayou Land Conservancy petitioned the Texas Commission on Environmental Quality (TCEQ) to establish best management practices for sand mines in the San Jacinto watershed. We didn’t get everything we wanted, but we got a vast improvement over what we had. And the new BMPs may help reduce erosion that contributes to future floods in this area.

West Fork Sand Mine illustrates need for vegetative controls to reduce erosion.

Relentless Development

Fueled by low interest rates and flight from city crowds during Covid, suburban and rural development surged in 2021. Flood-mitigation felt like an afterthought in many developments. We saw that with Colony Ridge in Liberty County. Colony Ridge clearcut wetlands, paved over floodplains and ignored county regs designed to reduce erosion.

In the Kingwood Area, the Laurel Springs RV resort took advantage of a grandfathering clause in permitting to build a detention pond one-half the size of current requirements. These represent just two examples of many.

The Laurel Springs RV Resort got its detention pond approved one day before stiffer regs went into effect.

After Harvey, we saw how such practices made flooding worse. How soon we forget!

Houston Housing and Community Development Meltdown

Houston’s Housing and Community Development Department, which was responsible for distributing more than a billion dollars in Harvey disaster relief funds, came unglued again this year. Last year, it sued the Texas General Land Office to keep money it couldn’t give away. This year, the Department’s Director publicly denounced the Mayor of Houston for trying to steer multi-family housing subsidies to the Mayor’s former law partner. The Mayor claimed ignorance of the partner’s involvement and announced a City Attorney investigation which never materialized.

Meanwhile, flood victims were victimized a second time. Bureaucratic bungling denied aid to people who deserved it.

World War II And Lake Houston Gates

May 9, 2021, was 1349 days after Hurricane Harvey ravaged Texas and the Gulf Coast. That’s the number of days it took the US and its allies to win World War II. But during that time we’ve had few victories in the fight against future flooding in the Lake Houston Area with the exception of dredging, So far, we’ve mainly completed studies. And many of those are still in the works.

For instance, the City of Houston has been studying ways to increase the release capacity of the Lake Houston Dam. Right now, the release capacity is one-fifteenth that of the gates on Lake Conroe. That makes it difficult to shed water quickly before and during floods. FEMA gave the City money to study the problem, but is still finalizing recommendations. The City hopes to make an announcement in January.

Lawsuits

The Lake Conroe Association had its lawsuit against the SJRA thrown out of court…with prejudice. The LCA hoped to prohibit the SJRA’s policy of seasonal lake lowering, which was designed to help protect the Lake Houston Area until other flood mitigation efforts could be put in place.

The Texas Attorney General is still suing the Triple PG Sand Mine in Porter on behalf of the TCEQ. There has been little movement on the case in the last 18 months. The mine’s owner changed legal counsel in July 2020. A TCEQ representative says the AG has not given up. The two sides are still in discovery.

Approximately 1700 homeowners in the Lake Houston Area sued sand mines for contributing to flooding during Harvey. The cases were consolidated in the 281st Harris County District Court under Judge Sylvia Matthews. She recently set deadlines in the first half of next year for motions, depositions, joinder, expert witness testimony and more. The case is known as “Harvey Sand Litigation.”

Various lawsuits against the SJRA for flooding during Harvey are still working their way through the legal system.

Kingwood residents reached a settlement with Perry Homes, its subsidiaries and contractors this year over two floods that damaged hundreds of homes in Elm Grove and North Kingwood Forest during 2019. The incidents had to do with development of Woodridge Village, just across the Harris/Montgomery County line.

Woodridge Village

Harris County Flood Control District purchased Woodridge Village from Perry Homes in February this year and hired a contractor to begin doubling the current floodwater-detention capacity on the site. When complete, the additional capacity will help protect homes in Elm Grove, North Kingwood Forest and downstream along Taylor Gully.

Expansion of Dredging

After three and a half years of dredging in the San Jacinto West Fork, dredging has now moved to the East Fork. State Representative Dan Huberty secured $50 million earlier this year to extend the dredging program to other inlets around Lake Houston in the future.

Bens Branch and Taylor Gully Cleanouts

In Kingwood, HCFCD finished excavating both Bens Branch and Taylor Gully to help restore their conveyance. Through gradual sediment built up, both had been gradually reduced to a 2-year level of service in places. That means they would come out of their banks after a 2-year rain.

Final phase of Bens Branch maintenance between Kingwood Drive and Rocky Woods. Note Kingwood High School in upper right.

Subsidence

Years of fighting over subsidence between the Lone Star Groundwater Conservation District and Groundwater Management Area 14 came to a head earlier this year. LSGCD fought any mention of subsidence in Desired Future Conditions (DFCs) for Montgomery County. GMA-14 wanted to include it, but finally recommended allowing each groundwater conservation district to make a subsidence measure optional. Unlimited groundwater pumping in southern Montgomery County could tilt Lake Houston toward homes at the northern end of the lake. That’s because subsidence would be greater there than at the Lake Houston Dam by TWO FEET.

GMA-14 will take a final vote on January 5 on the final DFCs. You still have time to protest.
