Giving Rivers More Room: Who Wants to Give Up The Freedom to Flood?

A CBS 60-Minutes segment last Sunday brought into focus many thoughts I have been struggling to articulate since Hurricane Harvey. The segment featured an interview with a Dutch flood expert named Henk Ovink. Mr. Ovink has some impressive credentials and consults with other countries and cities around the world. At a strategic level, he looks at America and scratches his strikingly bald head. You can sum up his observations in a paragraph.

Simple Flooding Solution: Reimagine, Don’t Replace

America, he says, spends hundreds of billions of dollars to repair flood damage and restore communities to the way they were. The Dutch, he says, focus on re-imagining their cities to move structures and people out of harm’s way. The idea is to give floods more room to spread out rather than to confine them within dikes. Instead of incentivizing people with below-cost national flood insurance to build ever closer to danger areas, reward them for moving to safer places.

Unfortunately, the 60-minutes segment is behind a pay wall. If you’re not a subscriber already, you can see many of the same thoughts in this 10-minute interview he did with the Canadian Broadcasting Company right after Hurricane Harvey and other massive floods in 2017.

Why Change is So Difficult

It’s not as if these are new ideas. We hear people talking about them ad nauseam – at conferences, on TV, in City Council chambers, in newspaper reports. Yet we never take action on them. As a result, homes and businesses flood repetitively. And people die. In contrast, no one has died in a Dutch flood since 1955, says Mr. Ovink.

This raises an obvious question.

What keeps us from adopting simple, low-cost, proven solutions?

The answer should be blindingly obvious, but isn’t … at least to Americans … and especially Texans, who believe in individual freedom and competition more than most.

If you take the time to watch Mr. Ovink’s other speeches and interviews on YouTube, you’ll get a hint. He talks a lot about the spirit of cooperation among the Dutch people. It’s not as if American’s don’t know how to cooperate. It’s that we don’t LIKE to cooperate – if there’s money to be made.

Cooperation Vs. Competition

From a sociological and psychological perspective, humans have two great survival strategies: cooperation and competition. You can see them built into our political fabric at every level, dating back to the U.S. Constitution. We built America on both. Fifty states work together to provide for things like a common defense. But we also have fifty states competing with each other for jobs, economic development, and the freedom to pursue different values.

The contradiction and tension between these two survival strategies defines the American mindset and American politics. Two local, recent examples:

  • Romerica is trying to build a 3.2 million square foot development in wetlands near the floodway of the San Jacinto West Fork. They know it’s not safe, but they can make money by buying up cheap flood plain land and then sell river views at a profit. Taxpayer-subsided flood insurance protects everyone. So why not?
  • In Montgomery County, a private water utility is fighting what it calls a “government monopoly” on the supply of water. QuadVest and Simon Sequeira want unlimited groundwater pumping to pump up their profits. They dispute the science that points to the subsidence it will generate, endangering other people’s property.

Lessons from the Pursuit of Loneliness

As I reflected on this, it reminded me of a book I read in 1970, The Pursuit of Loneliness by Phillip Slater. For a sociology book, it became a blockbuster success. It sold more than half a million copies, a monster number at the time.

The New York Times said in a review, “…the book explored the tension between the Lone Ranger individualist who occupies center stage in American myth and the communal interdependence that defines democracy in reality.”

The example I remember best from Slater’s book, which I read almost 50 years ago, concerned migration to suburbs and exurbs. For thousands of years, Slater said, to be civilized meant to be citified. We love all the benefits of living in a city (like jobs, shopping, cultural and sporting events), but our dream is a ranch far out in the country that lets us escape. So we buy it, then lobby to build an eight-lane divided highway to it. Use up two to three hours a day commuting. And pollute the air along the way. We wake up years later only to find that we have destroyed the very lifestyle we we fought so hard to attain.

The book is filled with contradictions like this. For instance, when connectedness brings us happiness, why do we work so hard to live in walled-off homes? I highly recommend it.

Group Vs. Individual

This conflict between cooperation and competition, independence and interdependence, defines the contradictions in our ambitions, politics and lifestyles. It’s what makes America and Texas so insanely great. It’s also one of the things that makes flood mitigation so difficult and expensive. Our belief in individual rights blinds us to the obvious. Maybe we should just give the river room to flood by turning that flood plain property into communal parks that everyone can enjoy. But who will give up their river view? Or the freedom to flood?

All thoughts expressed in this post are my opinions on matters of public policy. They are protected by the First Amendment of the US Constitution and the Anti-SLAPP law of the great State of Texas.

Upstream Development Should Not Affect Kingwood Like It Affected Bellaire, But…

Two new subdivisions, Northpark Woods and Woodridge Village, made me worry about the impact of upstream development on Kingwood and the rest of the Lake Houston area. Could these developments overwhelm the capacity of our drainage ditches? Could they increase our chances of flooding? The consensus among flood professionals: It’s not likely. But they also qualify their answers. Here’s why.

Clear-cut area for new Northpark Woods development in Porter. This 90-acre area will contain hundreds of starter homes in the flood plain of the West Fork (background), ranging from 1200 to 2400SF.

Changes in Detention Requirements Over Time

In the past, upstream development definitely contributed to downstream flooding in places like Bellaire and Meyerland. But that was back before regulations in most cities and counties required detention ponds in new developments. In many cases, no detention was provided for a development because it simply wasn’t part of the requirements of the time.

It’s different now for places like Kingwood because much of the upstream development has required and continues to require detention.

I found that very comforting. However, we also have some challenges ahead to reduce flood risk.

Not All Counties Have Fill Requirements As Stringent as Harris’

As we’ve seen with the Romerica development, Harris County has stringent requirements about filling in floodplains. Not all surrounding counties have those same restrictions. Can we do anything about that?

Kingwood can certainly advocate among all areas upstream that drain to Lake Houston. For instance, take Montgomery County, Waller County, Grimes County, Walker County, San Jacinto County, and Liberty County. Those and associated incorporated areas (e.g., City of Conroe) should not only require detention for new developments, they should adopt drainage criteria and regulations similar to Harris County.  

This would mean that new developments would have to mitigate not only for the increased stormwater runoff, but for any fill they add to the floodplain. 

Problems in Harmonizing Flood Plain Regulations

This is a big ask for many areas that are looking to attract development and growth. The problem: Many places on the fringes of the City see lax regulations (or a reputation for lax enforcement) as a way to attract growth. The implied pitch to developers is, “Your costs will be lower here.”

Complicating matters, many residents of those counties moved away from the City because they like the freedom. You just have fewer people telling you what to do out in the country.

So expect political pushback.

Consider as Part of First Statewide Flood Plan?

Even right here in the Lake Houston area, we have widely varying flood plain regulations.

Fortunately, we have a forum to debate this: the new statewide flood plan authorized by SB8 this year. Harmonizing flood-plain regulations should be part of our first-ever statewide flood plan. The lack of harmony certainly contributed to many of our woes during Harvey – especially when it comes to flood plain developments like Northpark Woods.

Statewide Flood Plan Meetings Coming Up

The Texas Water Development Board (TWDB) is inviting interested Texans to attend one of 13 flood outreach meetings during the first two weeks of August. They will solicit comments on the new state and regional flood planning process and the new flood financing program, both established during the 2019 legislative session under SB8 and SB500.

Texans are beginning the first stages in the development of a first-ever statewide flood plan.

Jeff Walker, Executive Administrator of the TWDB says the group is holding these meetings prior to the required formal rulemaking process to help ensure that the new programs meet the needs of Texas communities.

The flood planning program will result in regional flood plans in 2023 and the first state flood plan in September 2024. Intended to make drainage and flood projects more affordable for Texas communities, the flood financing program will be funded through a $793 million transfer from the Rainy Day Fund and will become available in 2020.

The 13 meetings are widely scattered throughout the state. The closest to the Houston area is in Tomball.

  • Beckendorf Conference Center at Lone Star College–Tomball
  • 30555 Tomball Pkwy. 
  • Tomball, TX 77375
  • 9:30-11:30 a.m.
  • Friday, August 9

Sign up for more information about these meetings and other flood information at the TWDB’s website.

Said Walker, “Your comments will help us craft programs that reflect the diversity and magnitude of the flood needs in Texas. We hope we will see you in August.”

Monitor Master Watershed Study

Additionally, the Kingwood area should closely monitor the San Jacinto River Watershed Master Drainage Plan currently underway.  This study will be the critical document that guides future decisions (and funding) for large flood damage reduction projects upstream of Kingwood. 

That includes more upstream detention like the Addicks and Barker Reservoirs. Additional detention was one of three critical remediation measures to help improve flood safety in the Lake Houston Area (detention, dredging and gates for Lake Houston – DDG).

Already some areas have been ruled out for additional detention because of new developments going in upstream. The study began last March after Houston, Harris County, Montgomery County and the SJRA obtained FEMA Hazard Mitigation Grant Program funds.

Those Who Deny History Are Doomed To Repeat It: Subsidence in 1974 and 2019

My post about Conroe escalating the Montgomery County water wars and putting millions of people in the crossfire from subsidence drew a response from Simon Sequeira, president of Quadvest. Sequiera is one of the litigants arguing for unlimited pumping of groundwater. On Facebook, he dismissively said, “Rehak has an elementary understanding of the issues.”

Who are Simon Sequiera and Quadvest?

Quadvest claims to be the “fastest growing, privately-owned utility company in Southeast Texas.” It has aggressive growth goals. Unlimited pumping of cheap groundwater would help them attain those goals. I consider Mr. Sequeira’s criticism with that in mind. He has some self-interest in this fight. If he wins, he gets even richer. Unfortunately, for millions of people in the Gulf Coast region, money has a short memory.

Denying History Means Learning the Hard Way

The history of Quadvest goes back only 40 years, so this 1974 Texas Monthly article about subsidence may not be part of Mr. Sequeira’s or the company’s institutional memory. William Broyles wrote it. Broyles helped found Texas Monthly and won numerous national magazine awards, one of the highest honors in journalism. Broyles later went on to a distinguished film career as a screenwriter.

The article, titled Disaster, Part Two: Houston, discusses subsidence. It begins with the story of a home – built less than 10 feet above sea level – that had subsided 10 feet in the previous 30 years, three of those feet in just the previous 10 years. The home was separated from the shore and surrounded by sand bags when Broyles wrote the article.

It was one of 448 homes in Brownwood, an exclusive subdivision in Baytown, that actually sank into Galveston Bay.

Cause of Subsidence

In the next paragraph Broyles discusses the cause: “Across the Houston Ship Channel, … the booming plants and industries of the world’s largest petro-chemical complex and the nation’s third largest port had set in motion an inexorable geologic process which destined their quiet neighborhood for the bottom of Galveston Bay. This great agricultural, industrial, and refining economy—and its population—have been fueled by 190 billion gallons of water a year, available easily and cheaply from industrial and municipal wells. These wells have steadily drained the Evangeline and Chicot aquifers (underground water storage systems) faster than they are refilled by annual rainfall. Each year the wells must go deeper to find water. Because of the region’s geology, water is a vital structural component of the clay and sand underlying the land surface; when it is removed, the land sinks.”

One aquifer in Montgomery County is being depleted 500 times faster than its recharge rate. This is clearly not sustainable.

Alternate Doomsday Scenario

Because of its proximity to sea level, Brownwood felt the effects of subsidence first. But the article goes on to discuss the effects of subsidence in the Sixties and Seventies on Pasadena, League City, Clear Lake, the San Jacinto Battle Ground, Galveston, Texas City, and the Johnson Space Center.

The doomsday scenario most feared then and now is a giant hurricane pushing storm surge up the Bay.

The specter of subsidence was so feared by the people of the time that it led to the creation of the Houston-Galveston Subsidence District by the Texas Legislature in 1975, just months after Broyles wrote the article.

Of course, most of Montgomery County is higher than the area bordering Galveston Bay. So why should Montgomery County residents worry?

Red contours show subsidence in last century. Blue contours show subsidence in first 16 years of this century. Note how the small red circle near Jersey Village (A) quickly expanded to the large blue circle around it. Also note (B) the widening gap between red and blue at the top of the frame. This shows that areas that depend on groundwater, i.e., Montgomery County, are subsiding faster than those on surface water, i.e., most of Harris County. Source: Harris-Galveston Subsidence District.

Water level declines start at the well locations where the aquifer is being overpumped.  They call the drawdown curves “cones of depression.” Any local district allowing unlimited groundwater pumping would be impacted first and most. Then the effects would spread to neighboring counties such as Harris and Liberty. This could reduce the gradient of the San Jacinto, causing floodwaters to move slower or accumulate in certain places. Jersey Village is already experiencing this type of flooding due to excessive pumping that put it in the center of a giant bowl.

Fault Activation and Property Damage

Broyles’ article goes on to describe another fear: the activation of faults. “Subsidence caused by massive water withdrawal from regions of high compressibility has also nudged into activity more than 1000 miles of faults. These faults, which generally run parallel to the coast, range in displacement from several inches to eight feet. Such a fault has caused the variation in subsidence at the San Jacinto Monument, where one end of the reflecting pool has sunk three feet and the other end six feet.” 

“This faulting,” continues Broyles, “… exacerbates the problems caused by relatively even subsidence; sewers, pipelines, foundations, sensitive catalytic units, and other highly sophisticated structures cannot survive faulting.”

A recent study by SMU, funded by NASA, confirms that fault activation is still a very real threat from subsidence in Montgomery County.

One economic geologist quoted by Broyles in 1975 characterized faults as “slow motion earthquakes.” There’s no shortage of pipelines, wells, and oilfield instructure. We should not forget that Humble Oil Company turned into one of the world’s largest brands, Exxon, and started right here. Also, there’s other infrastructure like roads, sewers and water distribution networks to be concerned about in northern Harris and southern Montgomery Counties.

Private Vs. Public Interest

If Mr. Sequeira is smart, he will pay close attention to the end of Broyles’ article. Broyles concludes with a discussion of a massive and messy class-action lawsuit between those fighting for unlimited pumping and those whose property was damaged.

Broyles said, “…People … endangered by subsidence are not accepting the extinction of their property … stoically.”

That should give everyone on both sides of the current water war lots to think about.

Many wells and pipelines run through the Lake Houston watershed. Hmmmm. Subsidence, faulting, ruptures, drinking water for 2 million people. It’s easy to see how this could get even uglier. Before there is any resolution, history may repeat itself.
