Welcome to Climate Psychotherapy

Two nights ago I started to hug my wife. “Not tonight,” she said. 

“What’s wrong,” I asked. “Headache?”

“No,” she sighed. “Climate change.”

The temperature in the room dropped about 10 degrees.

“I see what you mean,” I said.

Ironically, the next morning, I opened the New York Times to an article by Brooke Jarvis. The title: “Climate Change Is Keeping Therapists Up at Night: How anxiety about the planet’s future is transforming the practice of psychotherapy.”

It began with the experience of one psychotherapist to bring issues into focus. He said that many potential patients are looking for someone to talk to about climate change, only to be told (by others, not him) that they are overreacting.

Climate Psychology Alliance of North America and Eco-Anxiety

Enter stage left a group of about 100 “climate-aware” psychotherapists who call themselves the Climate Psychology Alliance of North America. According to Jarvis, they primarily deal with three types of issues:

  • Acute trauma of living through climate disasters
  • Fear of a collapsing future
  • Psychosocial decay from disruptive changes.

Collectively, they call it “eco-anxiety” or “a chronic fear of environmental doom.”

It’s not clear from the rest of Jarvis’ story whether the psychotherapists have reached any consensus yet about how to treat this emerging malady.

Conflicting Info About Breadth of Concerns

Jarvis cites a nationally representative 2022 survey of more than 1,000 people from Yale and George Mason University. Researchers found that a majority of Americans (64%) say they are at least “somewhat worried” about global warming.

However, Jarvis does not report that the same research also found about 90% of Americans experience no distress at all about global warming.

Should psychotherapists bring climate concerns up even when clients don’t? That’s not clear either.

But the climate psychologists agree that they should validate their clients’ climate-related emotions as “reasonable, not pathological.” The climate shrinks believe they should make clients feel their fear is a “rational response to a world that’s very scary.”

Link between Eco-Reporting and Eco-Anxiety Not Examined

While not denying climate change, I also personally believe the threat may be artificially exaggerated.

The New York Times article does not examine eco-reporting that contributes to eco-anxiety. Some days, I’m afraid to open a newspaper because I may find Republicans can’t elect a speaker…due to climate change. (Just joking.)

Comments on the New York Times article seemed polarized. About half felt eco-anxiety was justified. The other half felt it was manufactured by media.

In that regard, I have previously posted about the Associated Press policy of taking money from foundations with interests in renewable energy to hire 20 reporters who focus on climate change.

Before the Internet undermined local newspapers, news organization sold advertising to generate revenue that paid employees. Ads clearly showed client’s logos. News organizations jealously guarded their editorial integrity; news almost never crossed the line into advertising.

That’s no longer the case. Now, 20 reporters are looking for any way possible to connect random weather events to climate change…using the most tenuous of threads. And if they can’t find one, they say, “So-and-so worries that climate change may make his problem worse in the future.” But they present no real statistical proof.

Not to make light of anyone’s feelings or circumstances, as I scrolled through other headlines this morning, I learned that…

Such stories are rapidly becoming a parody of themselves. Regardless…

Repetition Makes Claims Rise to Level of Assumed Truth

Through sheer repetition of such claims day after day, people assume their truth. Individual events such as a flood, drought, freeze, heatwave or windstorm may or may not exemplify larger trends. But reports rarely present actual proof they do.

Rather, they quote people who have suffered some kind of weather-related damage and who fear such events may become more common in the future…due to climate change.

Of course, who can disprove the future? That’s pretty safe ground for a reporter.

I asked one of the area’s leading psychotherapists in Houston to review the New York Times article. She replied, “Climate change didn’t come up once in my 40 years of private practice.”

Flood Map Accuracy

On December 6, 2022, The Washington Post ran an article titled “America Underwater: Extreme floods expose the flaws in FEMA’s risk maps.” The lengthy story by Samuel Oakford, John Muyskens, Sarah Cahlan and Joyce Sohyun Lee cross-referenced photos and videos with FEMA flood maps from areas around the country that flooded last summer.

The basic premise: FEMA’s flood maps “are failing to warn Americans about flood risk.” The authors then claim, “The resulting picture leaves homeowners, prospective buyers, renters and cities in the dark about the potential dangers they face, which insurance they should buy and what kinds of development should be restricted.”

There’s certainly room for improvement in FEMA flood maps.

FEMA Map from National Flood Hazard Layer Viewer. Note how mapping stops at Montgomery County line, one of the issues cited in The Post article.

But is Climate Change the Reason for Inaccuracy?

However, the authors blame climate change for the inaccuracy far more than other contributing factors which are far more obvious.

FEMA is supposed to update flood maps every 5-10 years. It’s hard to imagine climate change invalidating them in that time period.

Climate is an average of weather occurring over much longer time periods. Depending on whether you talk to a meteorologist or a geologist, the time period could range from 30 to millions of years.

At least five major ice ages have occurred throughout Earth’s history: the earliest was over 2 billion years ago, and the most recent one began approximately 3 million years ago and continues today (yes, we live in an ice age!). Currently, we are in a warm interglacial that began about 11,000 years ago. The last period of glaciation, often called the “Ice Age,” peaked about 20,000 years ago. At that time, the world was on average probably about 10°F colder than today.

Interestingly, one day after The Post article, the New York Times ran a story about the DNA of animals found frozen in the permafrost of northern Greenland, just a few hundred miles from the North Pole. The 135 different species scientists found there paint a picture of an arctic once lush with life typical of warmer climates today.

But another thing puzzles me. I see climate change often mentioned as the reason for drought. The US Geological Survey states, “Climate change has further altered the natural pattern of droughts, making them more frequent, longer, and more severe.” But The Post uses almost identical language to blame climate change for frequent flooding in many of the same general areas at the same time. Which is it?

And to what degree can climate change explain flood map inaccuracy? Many more obvious reasons exist that are less of a stretch for any inaccuracies.

Reasons Listed in Post Article for Inaccuracy of Maps

Here’s a list of the references in The Washington Post story used to explain inaccuracies found within FEMA maps. I’ve broken them into two groups so you can see the weight they gave to climate change.

Climate-Change References:
  1. “As climate change accelerates, it is increasing types of flooding that the maps aren’t built to include.”
  2. “Extreme precipitation events are growing increasingly common.”
  3. “A warming climate allows storms to carry more moisture, producing greater rain or snow in a short period of time.”
  4. “Climate has changed so much that the maps aren’t going to keep up.”
  5. Maps are out of date, some decades-old “in a changing climate.”
  6. “The effects of a changing climate.”
  7. Climate change impacts are getting worse.
  8. Climate change is “pushing FEMA’s maps beyond their limits.”
  9.  A gap exists between the data that goes into FEMA maps and current climate conditions.
  10. Climate change baseline is changing.
  11. “Climate change velocities are high.”
  12. “Maps do not take climate change into account.”
  13. “Overestimating the rarity of some events even before climate change…”
Other Possible Explanations Mentioned by The Post:
  1. “Communities may resist expanding designated flood zones because it adds costs and can hamper development.”
  2. Not all areas that flooded are mapped yet.
  3.  “Local communities often resist the expansion of federal flood zones”
  4. “Maps do not forecast flooding. Maps only reflect past flooding…”
  5. “Local governments have been opposed to any maps that show an increasing risk.”
  6. Relatively high imperviousness of gentrifying areas.
  7. Maps don’t reflect intense bursts of rainfall in a short period and the resulting street flooding.
  8. Impervious surface is replacing porous surface.
  9. Maps cover mainly coastal and riverine flooding.
  10. “Rain combining with melted snowpack.”
  11. FEMA flood maps don’t even attempt to model urban flooding
  12. “City neglected drainage problems.”
  13. Local opposition to expanding the floodplain.
  14. No sense of urgency to update maps.
  15. “Multiple compounding factors contribute to the flooding”

However, the article makes no mention of the mathematical limitations of Extreme Value Analysis, the key to understanding the uncertainties associated with rainfall probabilities.

Floods Can Also Be Explained Without Climate Change

The second group of references in The Post article seems far more immediate, compelling and easily provable when explaining any inaccuracy found in flood maps. They’re certainly typical of what I have found in the Houston area.

For the past five years I have been researching instances of flooding in and around Harris County. I published more than 250 articles on different aspects of the 2019 Elm Grove floods alone. And I don’t recall one person ever blaming those on climate change.

Elm Grove did not flood during Harvey, but did flood on two much smaller rains in 2019. The difference? Clearcutting and insufficiently mitigated upstream development. Contractors clearcut approximately 270 acres immediately north of Elm Grove without building sufficient detention capacity before the rains fell.

Similar stories – with variations – have played out over and over again throughout the Houston region. For instance, we see developers filling in wetlands. Exaggerating the infiltration rates of soils. Underestimating impermeable cover. Building in floodplains. Building to outdated codes and floodplain regulations. Being grandfathered under old regulations. Various jurisdictions refusing to update regulations. And more.

Regardless of your position on climate change, this discussion dramatizes the needs to:

  • Understand your local flood risk and the factors that affect it
  • Buy flood insurance.

Hopefully, Harris County Flood Control District’s MAAPnext project will address data deficiencies discussed in The Post article. But it will be years before those maps become official. And when they do, the landscape will have already changed.

1931 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.

NOAA Adopts New Normal: Hotter, Wetter

NOAA has updated its climate statistics for the U.S. Every 10 years, the agency comes up with a “new normal” based on the last 30 years of data. The most recent 30 years, compared to previous averages, shows that our climate is getting hotter and wetter (at least in the Houston area).

Screen capture showing new “normal” temperature and precipitation for Houston Intercontinental Airport. Blue line represents precipitation. Orange = ave. minimum temp. Red = average temp. And dark red = average max temp.
Same data in tabular format.

The “normals” help farmers, energy companies, water managers, transportation schedulers and others whose businesses depend on weather plan their activities. That includes your local TV weather casters who constantly compare what they predict for tomorrow with what has happened in the past.

What’s Normal – From 30 years Down to The Hour

The NOAA stats come in annual, seasonal, monthly, daily and even hourly tables. Because the normals have been produced since the 1930s, they also help put current weather in a historical context.

The New York Times produced a series of animated “heat” maps that show changes in temperature and precipitation for those 30-year windows from the 1930s to today. Heat maps in this sense do not refer to temperature but to colors that reflect temperature or precipition differences. Hotter colors like red and orange reflect increases. Cooler colors like green and blue reflect decreases.

Choose Your Start/Stop Points Carefully

Curiously, the animations show the U.S. getting both hotter and colder through the decades. Likewise with wetter and drier. You can clearly see alternating cycles of hot and cold, wet and dry. As cycles come and go, where you chose your start and stop points lets you support or disprove your favorite climate change hypothesis.

The change is especially drastic between the new normals and the previous ones, from 2010. “Almost every place in the U.S. has warmed,” Dr. Michael Palecki told the Times. He manages the project at NOAA’s National Centers for Environmental Information.

Palecki claims the world has warmed by more than 1 degree Celsius (about 1.8 degrees Fahrenheit) since 1900, and that the pace of warming has accelerated in recent decades.

However, if you compared 1921-50 with 1941-70, you might think the world was cooling. The same goes for large parts of the county with dry/wet cycles. Although the Houston region has experienced increasing wetness on a fairly consistent basis, you can see drought ebb and flow through other parts of the country.

If you use 1900 as your start point and today as your stopping point, Palecki says the world has warmed by more than 1 degree Celsius (about 1.8 degrees Fahrenheit) and that the pace of warming has accelerated in recent decades.  The precipitation maps show the Southwest becoming increasingly drier, while the Central and Eastern parts of the country are getting wetter.

These two “heat” maps show the change in average annual precipitation and temperature during the previous 30-year reporting period and today’s.

Says NOAA, “Most of the U.S. was warmer, and the eastern two-thirds of the contiguous U.S. was wetter, from 1991–2020 than the previous normal period, 1981–2010. The Southwest was considerably drier on an annual basis, while the central northern U.S. has cooled somewhat.”

NY Times Covers Harris County Flood-Bond Spending, but Omits Spending Data

The New York Times ran a story on flood-bond spending, but forgot to look at where the budget to date has gone.

The story by Christopher Flavelle was titled, “A Climate Plan in Texas Focuses on Minorities. Not Everyone Likes It.” It outlined arguments on each side of the equity debate in flood-bond spending. From a balance point of view, it did a great job. However, it came up short in two areas.

Problems with Article

First, the headline misleads. This isn’t about climate. The story is about how to distribute flood-bond dollars equitably.

Second, it makes no mention of where flood-bond dollars to date have actually gone. Nor does it mention historical spending except in a generalized way. It implies poor people got none; rich people got it all. By avoiding research into actual current and historical spending, it perpetuated myths that do little to protect people from flooding.

Had the author checked, he would have found that those “underfunded,” disadvantaged neighborhoods have actually received 79% of the flood-bond projects to date.

Had he bothered to check historical or federal spending, he might have found an even more exaggerated pattern.

Trap Laid by Ellis

Mr. Clavelle fell into the trap that Commissioner Ellis laid. In effect, the argument goes like this. “Because homes in poor neighborhoods cost less than those in rich neighborhoods, it brings down the benefit/cost ratio for poor neighborhoods. FEMA considers that ratio in grant requests. That disadvantages grants for poor neighborhoods and perpetuates a downward cycle.”

That’s literally true – if you look only at FEMA grants. But it’s the exact opposite for HUD grants which heavily favor disadvantaged neighborhoods. Mr. Clavelle fails to mention that. As do Mr. Ellis and his surrogates whenever they talk on this subject.

Approximately 70% of those HUD grants MUST go to disadvantaged neighborhoods. The actual percentage varies by storm and type of grant. After Harvey, Harris County received a billion dollars. And the City of Houston received $1.1 billion. Together, that’s almost as much money as in the $2.5-billion flood bond. And there are still billions of additional dollars available from HUD through the General Land Office.

Preserve Your Community

If more of this money continues to go south, the Lake Houston Area is sunk in the next big storm.

But the County is considering a Community Resilience Task Force that would institutionalize this spending bias for the next 30 years.

The County Judge’s office is inviting the public to share their thoughts and ideas on the proposed draft bylaws of the Community Resilience Task Force. You can register your opinion from now until July 30th, 2020, via one of the following methods:

  • Email CRTF@cjo.hctx.net and submit comments digitally, beginning July 21
  • Join a virtual focus group via Zoom. After registering, participants will receive a confirmation email containing information about joining the meeting.
  • Offer input during the July 28th Commissioner’s Court

Please express your opinions to the county judge. Nothing is more important to the future of the Lake Houston Area than achieving more balance in flood-bond spending.

Some Key Facts to Consider

Some key points I intend to make:

  • 79% of flood bond projects to date have gone to neighborhoods that rate high on the social vulnerability index leaving only 21% to everyone else. We need to tweak the formula to achieve greater balance.
  • The argument that FEMA’s emphasis on Benefit/Cost Ratios disadvantages minority neighborhoods ignores the fact that billions of dollars in HUD grants advantage minority neighborhoods. Focusing only on one without acknowledging the other is intellectually dishonest.
  • HCFCD and USACE have historically underfunded flood mitigation projects in the Lake Houston Area. In the history of HCFCD, the District has not developed ONE USACE-funded project in this area.

For More Information

For more information on the “equity bias,” see this series on “Where Flood Mitigation Dollars Have Really Gone.” It was developed a year ago so the focus is on historical spending.

EPA Suspends Enforcement of Pollution Rules During Virus Epidemic

The EPA has suspended normal enforcement of air and water pollution rules during the corona virus epidemic. Critics fear it could cause more deaths. They also fear that rules forced through during the emergency could hamper future pollution control efforts. Specifically, a new, broadened rule would limit use of research based on confidential health information in regulatory decisions.

Full Text of EPA Memo

This 7-page memo from the EPA outlines the new policy. It says, the EPA will “generally not seek stipulated or other penalties for noncompliance…” The thrust of the memo: EPA is counting on industry to self-report violations. If violations relate to worker shortages due to the virus, EPA will not seek penalties. EPA will also give offenders time to remedy the situation.

Reaction from Interceptor

Sharon Lerner writes in The Interceptor that “EPA IS JAMMING THROUGH ROLLBACKS THAT COULD INCREASE CORONAVIRUS DEATHS.” The article cites the case of a Pasadena refinery exceeding benzene emission limits. It also cites problems in St. Johns, Louisiana. St. John reportedly has the highest cancer risk from air pollutants in the country. Area residents are routinely exposed to dozens of air pollutants, including the carcinogen chloroprene.

Residents worry that their weakened immune response from the chemicals will make them even more susceptible to the virus.

Review by New York Times

Lisa Friedman writes in The New York Times that “E.P.A., Citing Coronavirus, Drastically Relaxes Rules for Polluters.” The EPA, says the article, will focus during the outbreak “on situations that may create an acute risk or imminent threat to public health or the environment” and said it would exercise “discretion” in enforcing other environmental rules. In other words, they will focus primarily on the worst cases.

Ms. Friedman interviewed former EPA administrators. Gina McCarthy, who led the E.P.A. under the Obama administration and now serves as president of the Natural Resources Defense Council, called it “an open license to pollute.” Cynthia Giles, who headed the E.P.A. enforcement division during the Obama administration, said: “This is essentially a nationwide waiver of environmental rules. It is so far beyond any reasonable response. I am just stunned.”

A current spokesperson for the EPA, Andrea Woods, disagreed. “For situations outside of routine monitoring and reporting,” she said, “the agency has reserved its authorities and will take the pandemic into account on a case-by-case basis.”

Protest by 21 Environmental and Watchdog Groups

Meanwhile, Rebecca Beitsch reports in The Hill that “Coalition petitions EPA for disclosure as agency OKs suspension of environmental monitoring.” She says, “Environmental groups have characterized the memo as a license to pollute, as companies will not have to submit regular reports to the EPA showing they are not violating environmental laws.” She cites a petition spearheaded by the Natural Resources Defense Council which was signed by 21 environmental and watchdog groups. “We fully appreciate the disruption and harm caused by the COVID‐19 pandemic. But EPA’s unprecedented non‐enforcement policy creates a clear opportunity for abuse,” states the petition.

LA Times Reports on Reaction by California Officials

The Los Angeles Times reports in an article by Susanne Rust, Louis Sahagun and Rosanna Xia. “Citing coronavirus, EPA suspends enforcement of environmental laws.” The LA Times article focuses on the response of California officials. “The severity of the COVID-19 crisis should not be used as an excuse by the EPA to relax enforcement of federal environmental laws designed to protect public health and safety,” said Serge Dedina, mayor of Imperial Beach. His city, on the Mexican border, is under constant siege from pollution. “This crisis has only underscored why protecting public health and safety and our environment is more critical than ever.”

Is EPA Using Crisis as Cover to Make Concessions to Polluters?

Vox in an article by By Zeeshan Aleem claimed that “The EPA appears to be using coronavirus to make huge concessions to polluters.” It says the rule will remain in place indefinitely. And it gives factories, power plants, and other major polluters tremendous discretion. Now they can decide whether or not the coronavirus will prevent them from meeting legal requirements on air and water pollution and hazardous waste management. “Many experts and environmental advocates say that while case-by-case relaxation of rules for companies that are short-staffed due to the pandemic makes sense, the expansiveness of the EPA’s directive appears both unprecedented and designed to give a green light to polluters to act recklessly at a time when air quality is acutely important for public health.”

Other Reaction from Around the Country

For additional perspectives see:

Business Insider: The Environmental Protection Agency says it won’t enforce its own rules during the coronavirus pandemic.

USA Today: EPA suspends some public health monitoring and enforcement because of coronavirus crisis.

Texas Tribune: Citing coronavirus pandemic, Trump administration stops enforcing environmental laws.

CBS News: “An open license to pollute”: Trump administration indefinitely suspends some environmental protection laws during coronavirus pandemic.

An Associated Press Article in Marketwatch: Citing coronavirus, EPA has stopped enforcing environmental laws

The list goes on. A google search returned 11,800,000 results.

Will TCEQ Follow EPA Lead?

To say this is controversial would be an understatement.

At the very time when people’s lives and health are threatened by the virus, the EPA is dialing back enforcement of pollution rules that protect their lives and health.

At best, you could characterize the reaction to the new rule as “practical” given new constrictions we all operate under.

But, like the national press, I worry that this is part of a broader effort to dial back enforcement against polluters. We see examples of pollution threats right here in the Lake Houston area almost every month. And we saw them before the pandemic.

The day the West Fork ran white. TCEQ alleges Liberty Materials mine upstream dumped 56 million gallons of process water into the San Jacinto.
Aerial photo taken March 6 shows neighboring properties in foreground flooded by process water from the Triple PG mine in Porter, Tx. This process water migrated through the forest into the floodplain of White Oak Creek which ultimately leads to Lake Houston and the drinking water of 2 million people.

It will be interesting to see how the TCEQ reacts to the new EPA stance. Will they fall in line? I expect their report on the latest concerns about the Triple PG mine on Friday. The mine allegedly violated the terms of a temporary injunction in its case with the Texas Attorney General. Stay tuned.

946 Days after Hurricane Harvey

When Measured by Growth of Impervious Cover, Texas Has 9 of Top 20 Counties in U.S.

According to a recent New York Times article, nine of the 20 counties in the U.S. that have experienced the most development the last decade are in Texas. Prominent among them is Harris County. The article does not cite population growth. Rather, it relies on computer analysis of satellite imagery that detects the growth of impervious cover.

Analysis of Satellite Imagery Shows Land Newly Paved or Topped With Buildings

The Times cites the work of Santa-Fe-based Descartes Labs, which positions itself as a data refinery. The company trained a computer model to automatically identify newly impervious surfaces — land that appears paved or topped with buildings — in satellite imagery. It then produced dozens of paired images that show the effects of development. It also produced a map that shows where that development took place.

This Descarte map clearly shows the pattern in Texas. Each of the major cities looks like a bullet hole in the map with development splashing out ward…a ring of concrete.

Return of Suburban and Exurban Growth

The data suggests that the growth of suburbs and exurbs has returned. There was a brief hiatus of suburban development after the housing bust in 2008, which saw people returning to the inner city. But that trend appears to be over, according to this analysis.

I’m not sure if this should be a source of pride, alarm or both.

Texas Grows While Other Areas Lose Population

Many Rust Belt cities are experiencing population shrinkage. That presents another set of problems altogether. The Times article shows how several northern cities, including Detroit, are clearing thousands of dilapidated and abandoned homes. In the process, they are restoring pervious (natural) cover.

As luck would have it, another article in The NY Times the next day talked about a slowdown in U.S. population growth. Population grew at its slowest pace in decades in 2019. A decline in the number of new immigrants, fewer births and the graying of America accounted for the decline, which the Census Bureau estimated.

Given slow population growth on the national level, local growth in Texas and Houston must come from migration. I’m not talking about foreign immigration. I’m talking about one area attracting residents and businesses from another.

Texas Has Seven of Fifteen Fastest Growing Cities in U.S.

In marketing, if the market itself is not growing, the only way for a company to grow is to steal share from its competitors. And that is exactly what Texas seems to be doing. Markets such as New York and California are losing population while Texas gained more than 14% in the last decade. From 2010 to 2018, Texas had the largest population growth in America: 3,555,731.

Texas also had 7 of the top 15 fastest growing cities in the country between 2017 and 2018.

So clearly, from a marketing point of view, Texas must be seen as a desirable place to live by many people. We’re doing many things right.

Can Texas Meet the Challenge of Rapid Growth?

But in my 45 year career in marketing and advertising, I have seen many instances where companies had record growth one year only to have record losses later. It comes down to how you manage growth.

Can you deliver what you promise and keep product quality up as you grow?

Many areas can. Many areas can’t.

County officials face a conundrum: growing rapidly while maintaining quality of life. You want to attract growth, but you don’t want to be overwhelmed by it.

Montgomery Vs. Fort Bend Counties: Strategic Differences

Some compete for growth by relaxing regulations. For instance, this video from the East Montgomery County Improvement District boasts, “We don’t have rules that confine us.” The no-hassle upfront, anything-goes, follow-your-dream approach tempts many, especially those coming from other areas with onerous regulations.

Meanwhile, other fast-growing counties, such as Fort Bend, are adopting new flood plain regulations, designed to protect the quality of life they are selling.

Tougher Fort Bend County Regulations Went Into Effect New Year’s Day.

As of 1/1/2020, Fort Bend County adopted new Atlas 14 rainfall statistics and updated their drainage criteria manual accordingly to protect new homes AND existing downstream developments. Fort Bend is the fastest growing county in the region.

There you have it. Two opposite ends of the spectrum.

It will be interesting to see the outcomes that these two development strategies produce ten years from now.

NY Times Article Says Quarter of Humanity Facing Looming Water Crisis

An article in the New York Times about a looming water crisis caught my eye today. Datelined Bangalore, India, the article describes how “Countries that are home to one-fourth of Earth’s population face an increasingly urgent risk: The prospect of running out of water.” So what does that have to do with flooding? Many of those countries also experience cyclic flooding. Sound familiar?

Uncanny Parallels to Houston

In yet another uncanny parallel to our situation – i.e., with the Water Wars in Montgomery County – “…some are squandering what water they have. Several are relying too heavily on groundwater, which instead they should be replenishing and saving for times of drought.”

And then we have the subsidence parallel. Mexico City, claim the authors, draws groundwater so fast that the city is literally sinking.

In Chennai, India’s fourth largest city, residents accustomed to relying on groundwater for years now find none left. So the city is forced to transport water from farther and farther away (like our Luce Bayou Project). They lose significant amounts in the process due to evaporation and leakage.

The World Resources Institute expects the number of people worldwide living in “extremely high water stress” to nearly double in the next decade.

Cape Town, a city roughly the size of Houston, had to ration water last year.

Drought and Flooding Solutions Often Overlap

In Bangalore, lakes that once dotted the city have been filled in, much the way we fill in wetlands, so they can no longer collect rainwater and serve as the city’s water storage tanks.

That parallel reminded me of the dwindling water capacity in Lake Houston due to sedimentation. With backup supplies in Lake Livingston and Lake Conroe, Houston certainly doesn’t have to worry about running out of water any time soon. But as recent sedimentation surveys near the mouth bar showed, we do have to worry about loss of lake capacity.

Difference map developed by Tetra Tech for City of Houston in Feb/March, 2019, showing areas of deposition and scour near the West Fork Mouth Bar. Overall, Tetra Tech estimates that this small 350-acre area of Lake Houston gained 504-acre feet of sediment since the previous survey in 2011. Brown areas represent more than 5 FEET of deposition.

Drought and floods represent two sides of the same coin. This article reminded me that solutions to one problem can also help solve the other. For instance…

  • Developing adequate surface water supplies and saving ground water as the backup. This can reduce subsidence which can lead to flooding.
  • Improving lake/river capacity by dredging can eliminate blockages that also cause flooding.

As we move forward with West Fork and maintenance dredging, we should remember this. We aren’t just looking at costs that benefit Lake Houston residents. We’re looking at costs that benefit millions of residents in the larger metropolitan area. It’s not just about flooding. It’s also about water capacity for a rapidly growing population.
