Seitzinger states in the opening that flooding cannot be eliminated when you get as much rainfall as we did with Harvey. But then goes on to say that, “There may be ways to limit the flooded areas in future.” His paper is intended to provide a better understanding of what happened. He hopes this will help design remedies that make the area more resilient to flooding.
River Obstructions Creating Backwater Effects
Seitzinger identifies six river obstructions creating backwaters:
The narrow Riverway near Lonestar College/Kingwood
The I-69 Bridge
A sand bar by the Kingwood Country Club
The Stream Mouth Bar
The 1960 Bridge
The Lake Houston Dam
He then spends the next 70 pages analyzing what happened at each of these during the flood and developing various strategies to deal with them. He breaks his recommendations up into short- and long-term.
Short-Term Recommendations
Short term recommendations include:
Establishing a regional authority to provide multi-county coordination on legislative, operation, mitigation and funding efforts for flood control
Reviewing and updating SJRA and CWA water release protocols.
Installing additional water-flow and level gages on the tributaries and Lake Houston with predictive flow algorithm.
Providing a better flood warning system for the general public.
Reviewing and legislating new sand-mining procedures and enforcement fines to prevent sand loss into the rivers during high water
Reviewing communications. Include clear regional decision maker assignments and house-to-house warnings for all homes in the floodway and below the 100 yr. levels at a minimum
Removing West Fork sand bars to re-establish main channel flow
Annual West Fork maintenance dredging.
Long-Term Recommendations
Longer-range recommendations for investigation and implementation include:
Dredging to return channel depths in West Fork and East Fork to original depths
Adding additional, controlled, water-release capability to Lake Houston
Widening the 59 bridge and FM 1960 bridge channels
Widening the 59 bridge and West Lake Houston Parkway bridge entrance and exit channels
Stopping flood plain re-development west of Hwy 59
Setting new regulations for storm zoning and land reservation
Adding controlled storm reservoirs to Cypress, Spring, and Lake Creeks and East Fork
Develop public-private partnership for river-sand removal and reclamation.
Limitations of Study
Seitzinger’s presentation is very technical; it is not easy reading. He targets other engineers with this and requests peer review.
One thing that will require validation: his velocity calculations. They seem at odds with velocities reported by rescue workers. I talked to an HPD officer, for instance, who estimated velocity in the vicinity of the West Lake Houston Parkway Bridge at 10 to 20 miles per hour. By calculating peaks as they moved downriver, Seitzinger estimates 1.03 mph. The difference could have to do with water jetting through the bottlenecks that Seitzinger describes. Unequal distribution of rainfall across upstream tributaries could also affect offsets among downstream peaks. Regardless…
Value of Study
Seitzinger provides all the data for others to check his calculations. The main value of an effort like this is that it collects all the crucial data in one place for posterity, cross-examination and comparison.
Kingwood is lucky to have many talented engineers, such as Seitzinger. This should stimulate much discussion.

The U.S. Army Corps of Engineers supplied this graphic. It updates the public on the latest dredging progress.
Two dredges, moving west to east (left to right), expect to complete dredging by the end of April, seven weeks from now. It was originally a nine month project scheduled to end around April 1, but heavy weather and multiple floods during December and January set the contractors back.
Great Lakes Dredge and Dock operates the red dredge that started at River Grove Park and is working its way toward the project midpoint.
Callan Marine operates the blue dredge that started at the midpoint and is working its way toward the end.
With roughly 50 days remaining (about 15-20% of the time depending on how many weather days you allow), the corps appears to be about 70% done. That means they must hustle to make up time. The contractors are already working 24/7.
Parents who want to give their kids a treat can take them down to Kings Harbor to watch the dredging. I was there today. It is truly impressive. There’s lots of big equipment on the river moving more sand than the Astrodome can hold. They’re pumping it miles upriver to two old sand pits.
While at Kings Harbor sample some frozen yogurt or one of the restaurants that recently re-opened. Please support the local merchants who bet their financial futures to make your life a little more enjoyable.
Yesterday, I learned about re-traumatization of people suffering PTSD (post-traumatic stress disorder) from Harvey. I had contacted Janice Costa, one of Kingwood’s leading psychotherapists to gain some insight. Keep in mind as you read this that neither Costa, nor I, have any idea how widespread this phenomenon is. However, Stephen Costello, the City of Houston’s flood czar, while speaking to a symposium on flooding at the University of Houston last year stated that 18% of Harris county’s residents suffered some sort of serious psychological distress after Harvey.
From presentation by Stephen Costello to Houston Geological Society in 2018 during a symposium on Flooding in Southeast Texas: The Science Behind the Floods. Costello said 18% of Harris County residents were suffering from “serious psychological distress” after Harvey.
I pointed out to Costa how the traffic on my site spiked when I posted The Night 11,000 Lake Houston Area Residents Became Homeless. Thousands of people have viewed it in the last week and are still viewing it. In fact, it’s my most popular flood post ever with the exception of the one with that snappy headline, Public Notice.

What Did I Tap Into?
I had accidentally tapped into some powerful emotions, but I wasn’t sure what or why and hoped Costa could help. Costa said victims sometimes feel such images and stories “validate” what they went through. “Yes! See. It was that bad!”
In the case of Harvey, it’s difficult for some people to let go, because they are constantly getting “re-traumatized” from related sources, she says. The examples below represent my interpretation of what she said, not literally what she said. I added dozens of examples that people have shared with me along the lines she mentioned.
Re-Traumatization, Day after Day
As if Harvey weren’t a big enough disaster, how about these complications? Do any of them sound familiar?
Flooding, but not having flood insurance, because you thought you were safely outside the 500-year flood plain
Power outages, spoiled food, Igloo coolers and grilling in the rain
Food lines, second-hand shops and shelter life
Separation from families, not being able to find loved ones in the shelter system
Loss of important papers, tax documents, and family albums
Losing the Bible that had been in your family for five generations
Gutting your own house, often with the help of strangers
Not being able to monitor everything they dragged to the curb
Seeing your life’s work piled on the street and picked over by looters
Your first Christmas without wallboard
Family heirlooms destroyed
Showering with a garden hose
Being displaced and dispossessed
Being forced to accept charity instead of feeling privileged to give it
Finding temporary lodging with friends, family or in hotels
Moving every few weeks so you didn’t wear out your welcome
Finding a vehicle and then finding out it had concealed flood damage
Stress at work from not being able to focus on your job while you rebuilt your life
The bad performance review at work that you knew was coming
Losing a business
Kids who cried themselves to sleep every time it rained
Breaking out in a cold sweat when you hear a helicopter
Feeling guilty about not being able to thank all the people who helped you
The two extra hours a day you didn’t get to spend with your kids because they were being bussed cross town to another high school.
Report cards that showed plummeting grades because your kids were traumatized
Educational handicaps that your kids may face for the rest of their lives as a result of effectively losing a year
Living in a camper
Your insurance benefits running out before repairs were completed
Losing your job
Losing your mind
Losing your spouse from all the stress
Trying to find money to rebuild
Living out of your car
Not having a car to live out of
Battling with the insurance adjuster
Battling with FEMA
Looking for help and battling a million other people looking for help
Struggling to find a contractor
Struggling to get the contractor to show up and do the work
Giving up the family vacation to supervise a contractor who didn’t show up
The contractor who ran off with your check
Finding out that the contractor hung your new front door upside down
Shoddy repairs with inferior materials
The City inspector who said the contractor did it all wrong
Lung ailments from breathing that unique Houston brew of mold, varnish, plaster dust and Clorox
Seeing friends and relatives succumb to the stress
Friends moving away to escape the stress
Going to the laundromat and using the machine next to the guy who was washing the clothes he had on
Living upstairs for a year and a half
Using your garage as a walk-in closet
Actually beginning to think of Taco Bell as haute cuisine
Learning to cook with a hot plate and a microwave
The stress zit that looked like a third eye in your forehead
Your favorite stores and restaurants being out of business for a year … or disappearing altogether
Going to college classes in a rented warehouse
Commuting two extra hours a day because the 59 bridge was out
Draining your retirement funds to rebuild
Then finding that wasn’t enough and tapping into your kids’ college funds
Not knowing how you’ll replenish them
Gaining 20 pounds from Chunky-Monkey stress relief
Jaw and neck pain from constantly grinding your teeth
FEMA and HUD help that arrived after you’d already rebuilt your home
Discovering that you lost all your repair receipts
Aches and pains from doing-it-all-yourself
Learning to love scratch-and-dent sales
Refurnishing your house from “Flooding Kingwood with Kindness”
Losing someone to cancer or heart-disease while trying to cope with everything else
The neighbor that abandoned the house next door…affecting your home’s value
Fearing what the next storm front could bring
My apologies to anyone I omitted!
More Re-traumatization!
Now consider the political systems around you. While we struggled individually, government offered help. Then came other kinds of re-traumatization.
The money from the drainage fee that wasn’t there when the City needed it to jumpstart flood mitigation projects
Being told you could build a firewall around drainage fees by approving the same leaky-bucket, Prop-A language that led to the problem in the first place
Learning that it took FEMA, the SJRA, Montgomery County, Harris County, and the City of Houston a year to fund a $2 million San Jacinto watershed study.
Wondering what that portends for the future of other flood mitigation projects
Watching that wonderful feeling of post-Harvey bipartisanship degenerate into political bickering while you…
Fear what the next storm could bring
The Lifeboat Mentality
In my opinion, people are looking for help and seeing hurt ahead. Many SAW the flood bond as a lifeboat. It buoyed their hopes and dreams for a return to safer shores. They were counting on the mitigation projects in it to protect them. Now, they feel thrown overboard by the struggle over prioritization of projects, i.e., who gets theirs first.
Our county judge called it “class warfare.” Fox News called it “bait and switch.” I call it maddening. I think residents rich and poor would agree.
Residents who suffer from PTSD, have suffered re-traumatization – so severely, so many times – that they may feel there is no escape. Political jousting just re-traumatizes them.
No one is telling them that more than half of the flood bond projects have started already.
Meanwhile, depression, anxiety and related illnesses are starting to surface. One of my dear friends lost her home to Harvey, her husband to cancer, and now is struggling with cardiac issues as she tries to rebuild her home. Alone.
Turning Negatives into Positives
Costa did offer a ray of hope. Some people have managed to find something positive in the flood experience, she said. For instance, those intent on remodeling might suddenly have the insurance money to do it.
One of my dreams is that Republicans and Democrats find a way to work together again. Maybe, collectively, we’ll find a way to create a functioning government that reduces flood risk and restores a sense of order to our lives in time to handle the next big hurricane. I think that would be a positive outcome from all of this. For all of us.

Seitzinger Contributes Second Study on Harvey, Addressing Timing and Backwater Issues
David Seitzinger, P.E., a Kingwood-based engineer, has contributed another study to the discussion of Hurricane Harvey. He titled the first one, SJR Flooding: Causes, Impacts, Potential Solutions. The second, SJR Flooding: Water Levels, Flows and Timing, does an even deeper, 92-page dive into the data.
Scope and Purpose
Seitzinger states in the opening that flooding cannot be eliminated when you get as much rainfall as we did with Harvey. But then goes on to say that, “There may be ways to limit the flooded areas in future.” His paper is intended to provide a better understanding of what happened.
