Mark Your Calendar: Important Meetings Related to Flooding

This month, you have three opportunities to attend meetings that could help reduce flooding in the Lake Houston area.

TWDB Visits Tomball to Solicit Input on State’s First Flood Plan

On Friday, August 9, the Texas Water Development Board (TWDB) will hold a meeting in Tomball. Purpose: to solicit public opinion on rules and guidelines for Texas’ first statewide flood plan. Here’s more information about the event and the TWDB. The TWDB is the state’s water agency. It’s primary mission is developing and maintaining lakes and reservoirs that support economic growth. This year, the legislature put them into the flood mitigation business, too. They’re looking for the best ways to spend $800 million on flood mitigation from the state’s Rainy Day Fund. TWDB will hold the event at:

  • 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. You can also contact the TWDB at (512) 463-8725 or flood@twdb.texas.gov.

TWDB Makes Repeat Appearance at Houston City Hall

If you can’t make the event in Tomball, you have another chance. TWDB will repeat the event at:

  • Houston City Hall
  • Council Chamber, 2nd Floor
  • 901 Bagby Street
  • Houston, TX 77002
  • 9:30 to 11:30
  • Friday, August 23

Montgomery County Will Hear Testimony on Closing Detention Loophole

On Tuesday, August 27th, Montgomery County Commissioners will consider a motion to close a loophole that allows developers to avoid building detention ponds. Expect developers to testify against closing the “flood routing study” loophole. You can testify FOR closing it, however.

The meeting starts at 9:30. Montgomery County has special sign-up procedures for citizens who wish to testify; make sure you sign up beforehand. Check the agenda beforehand to plan your time. You can also register your opinion with county commissioners via phone or email.

You don’t have to be a Montgomery County resident to testify. As downstream residents of the Lake Houston Area, you may be affected by this more than Montgomery County residents are.

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.

Humankind’s Love-Hate Attraction to Water

Two days ago, I posted a story about a community on the Bolivar Peninsula that Hurricane Ike totally destroyed. Owners have virtually rebuilt it. This isn’t a unique story. Around the world, around the county, on coast after coast and river after river, similar stories abound. FEMA calls floods the most common form of natural disaster. The Agency says Americans have a 26 percent chance of experiencing a flood during the life of a 30-year mortgage, compared to a four percent chance of fire. So people obviously love water views despite the risk. They even pay a premium for them. Why is there such an attraction to water?

Pragmatic Attractions

Historically, oceans were our earliest highways and busiest trade routes.

Water attracts us for other logical reasons, too. We need water for drinking, cooking and bathing. According to the U.S. Geological Survey, each person in the United States uses eighty to one hundred gallons of water every day for what we consider our “basic needs.” The United Nations declared, “Safe and clean drinking water is a human right essential to the full enjoyment of life.” We can’t live without it. But given modern technology and our ability to pump water over long distances, pragmatic considerations alone cannot explain our attraction to it.

Oceans and rivers also provide abundant protein year round. Wallace Nichols, author of the Blue Mind, wrote in Salon.com that, “The number of food and material resources provided in or near the water often trumped what could be found on land. The supply of plant-based and animal food sources may vanish in the winter, Eriksen observed, but our ancestors could fish or harvest shellfish year-round. And because the nature of water is to move and flow, instead of having to travel miles to forage, our ancestors could walk along a shore or riverbank and see what water had brought to them or what came to the water’s edge.”*

Biological Attractions

Nichols, also notes that, “Our innate relationship to water goes far deeper than economics, food, or proximity, however. Our ancient ancestors came out of the water and evolved from swimming to crawling to walking. Human fetuses still have “gill-slit” structures in their early stages of development, and we spend our first nine months of life immersed in the “watery” environment of our mother’s womb.”

“When we’re born, our bodies are approximately 78 percent water. As we age, that number drops to below 60 percent — but the brain continues to be made of 80 percent water. The human body as a whole is almost the same density as water, which allows us to float. In its mineral composition, the water in our cells is comparable to that found in the sea. Science writer Loren Eiseley once described human beings as “a way that water has of going about, beyond the reach of rivers.”

Psychological Attractions

Nichols cites the story of researchers at Plymouth University in the United Kingdom. In 2010, they asked forty adults to rate more than one hundred pictures of different natural and urban environments. Respondents gave higher ratings for positive mood, preference, and perceived restorativeness to any picture containing water, whether it was in a natural landscape or an urban setting, as opposed to those photos without water.

One of my close friends and photographic mentors is Gary Faye. Faye is one of America’s greatest living landscape photographers. His images exude serenity and often mystery…as in this shot of a swing in the Salton Sea. At a root level, it says, “This doesn’t belong here.” Much like the homes once destroyed by Ike, rebuilt just feet from the Gulf of Mexico on a dwindling spit of sand barely five feet above sea level.

Years ago, Faye told me that his images showing water outsold his other work by a considerable margin. He has since refined his explanation. “It’s not just the presence of water in the image,” he says. “It’s the sense of peacefulness and serenity that it communicates.”

Indi Maxon writing in Basmati agrees. “Spending time near natural bodies of water instills a feeling of calmness and ease of mind.”

Population Distribution Reflects Attraction to Water

Regardless of the reason, you can see people’s preference for living near water in the world’s population distribution. Recent studies have shown that the overwhelming bulk of humanity is concentrated along or near coasts on just 10% of the earth’s land surface.

In the United States, counties directly on the shoreline constitute less than 10 percent of the total land area (not including Alaska), but account for 39 percent of the total population. From 1970 to 2010, the population of these counties increased by almost 40% and are projected to increase by an additional 10 million people or 8% by 2020. Coastal areas are substantially more crowded than the U.S. as a whole, and population density in coastal areas will continue to increase in the future. In fact, says NOAA…

The population density of coastal shoreline counties is over six times greater than the corresponding inland counties.

The U.S. Census Bureau’s official population estimates, Between 1960 and 2008, the population in coastline counties along the Gulf of Mexico soared by 150 percent, more than double the rate of increase of the nation’s population as a whole.

Eight of the top ten largest cities in the world are located by coastlines.

As of 1998, over half the population of the planet — about 3.2 billion people — lives and works in a coastal strip just 200 kilometers wide (120 miles), while a full two-thirds, 4 billion, are found within 400 kilometers of a coast.

Living and Dying with the Water Paradox

So are people who build homes mere feet from the shoreline crazy? Or are others crazy for thinking they are crazy? It would seem that:

  • Proximity to water is hardwired into our DNA
  • Living near water, which has both benefits and dangers, is the norm.

I call this attraction to living in a danger zone the Water Paradox. What to do about it? You can’t fight it. Maybe we just need to plan and build better. Personally, I’m still searching for answers.
