Secrecy surrounds current dredging plans for the mouth bar of the San Jacinto West Fork. We know that the Corps will finish removing 500,000 cubic yards next week. However…
Unkowns at This Time
… we don’t know exactly where they are removing sediment, how wide the area is, how deep it is, and whether they will cut a channel through the sediment dam or just shave some off the top.

The Corps’ refusal to divulge plans puts residents in a bind. How can we know whether they have restored conveyance and safety? We must take their word. We don’t even have a post-dredge survey showing us how they intend to leave the river.
Two Prominent Geologist Suggest Objectives
With those caveats in mind, I asked Tim Garfield and RD Kissling what objectives they would set to restore conveyance and safety. Garfield and Kissling are two prominent area geologists who first brought the mouth-bar problems to the public’s attention. Between them, they have more than 80 years of oil field experience at the highest levels, studying river basins around the world.
Here’s how they responded: “Our overriding objectives are simple:
Restore flow conveyance of the west fork into Lake Houston
Survey the entire area being dredged for depth upon completion.
Extend the upstream dredging which ended near Kings Harbor through the mouth bar area. Said another way, don’t make water flow uphill. Eliminate the ramp.
Continue the 400’ wide, approximately 20′ deep channel past the SMB until it connects into the relict channel where it is 20’ deep or deeper near the FM1960 bridge.
Develop and implement a plan for regular maintenance dredging.
Define responsibilities, budget and source of funding for future dredging.
Define a schedule of regular depth surveys in order to determine where sediments are re-accumulating and to have a better baseline for future storm events.
Build and utilize 2D- or 3D-models to help guide future dredging decisions.
Resolve disposal issues. Identify long-term placement areas and potential partnerships with industry.”
Who Will Achieve Desired Results?
These objectives make sense to me. They describe what the river used to look like before the mouth bar set up and contributed to flooding 7,000 homes and businesses. They also describe what we need to do to keep the problem from recurring. If the Corps doesn’t achieve the desired result, I hope the City, Harris County and State can. You can help by urging elected representatives to get FEMA to designate the mouth bar sediment as Category A.
Corps May Share Results When Dredging Complete
According to Congressman Dan Crenshaw’s office, the Corps has finally agreed to share with outside sources the 1D HEC-RAS model it built. Reportedly, the Corps sent a copy of the model and data to Stephen Costello, the City of Houston’s Chief Recovery Officer. Crenshaw’s office is also trying to obtain the Corps’ dredging plans and make them public.
It will be interesting to see how the Corps’ dredging results line up with Garfield’s and Kissling’s objectives.

Having barely scratched the surface of the mouth bar of the San Jacinto West Fork, FEMA and the Army Corps will pack up their gear next week and call their job done. Last-ditch pleas by the City of Houston, Harris County and the State of Texas to get the federal government to extend its dredging program have fallen on deaf ears, perhaps because of the shifting of disaster relief funds to the construction of migrant detention facilities.

Regardless, the bottom line is this: the Corps and FEMA will leave millions of cubic yards of sediment in place without restoring conveyance of the West Fork to a prior good condition.
The pullout caps months of arguments over how much sediment Harvey deposited. The City estimated 1.4 million cubic yards and the Corps 500,000.
According to City Council Member Dave Martin, the Corps agreed Harvey deposited 1.4 million cubic yards of sediment in the river near the mouth bar. The Corps also agreed, said Martin, that there was nothing wrong with the Tetra Tech study that arrived at that total.
Waffling by Corps
As late as last Friday, Martin said, the Corps agreed to write a letter to FEMA, recommending dredging more than the 500,000 cubic yards. The letter would say that almost a million cubic yards of Harvey-related sediment remained in the river and should be removed. However, at a meeting in Austin this Tuesday, the Corps revealed that FEMA told it not to write the letter. The Corps now intends to demobilize equipment as soon as it finishes dredging 500,000 cubic yards from the mouth bar. That should only take until next week.
With the year-long dredging program now almost complete and perhaps less than a quarter of the sediment removed that is required to restore the natural flow of the river, what will happen next? We have some hope.
The Corps has finally approved Berry Madden’s property as a storage site for 500,000 cubic yards. That should be enough to get the next phase of the program started while the City seeks additional storage sites.
The City has committed to a maintenance dredging program according to Martin.
The State and Harris County have earmarked $30 million and $10 million respectively to continue dredging.
Tell them that you support the Category A designation and see the mouth bar removal as crucial to public safety with a letter like the one below.
Sample Letter
Subject: PLEASE CLASSIFY MOUTH BAR REMNANTS AS CATEGORY A
Dear _____________:
Thank you for helping to make dredging of the San Jacinto West Fork a priority. It will help reduce flooding, protect property, save lives, and improve public safety.
However, part of the existing mouth-bar located at the confluence of the San Jacinto River and Lake Houston remains.
I’m writing to enlist your support in urging the Federal Emergency Management Administration (FEMA) to designate that remaining debris as Category A for reimbursement.
Category A designation will allow the City of Houston to:
Utilize existing resources and pre-positioned contracts
Save nearly $20 million associated with mobilization
Protect life, property and safety
Field data collected by the City of Houston and provided to FEMA demonstrates that the remaining debris was directly associated with Hurricane Harvey. As of August 20, 2019, the City of Houston has proactively secured a third United States Army Corps of Engineers permitted disposal site needed for the additional debris.
Your assistance is crucial to rehabilitate the San Jacinto River to its prior good condition. Please urge FEMA to grant this Category A designation. It will let the City of Houston continue rebuilding from Harvey.
Sincerely,
INSERT

Sam Cleveland, a Houston Police Officer, started working in Kingwood the day Harvey made landfall two years ago. He is now running for City Council District E. Below are some of his observations on flooding, in part, based on his experience as a first responder.
The night of May 7th in Elm Grove Village
Reporting for Duty as Harvey Struck
Two years ago, almost to the day, I reported to Kingwood Police Station for duty at 07:00 am for my first day back after two days off. That day was August 25, 2017, and it would become an event that would leave a lasting impact on our city.
As we sat in roll call, we knew Hurricane Harvey would be making its appearance at some point during our shift. My day started off dry, then to light rain and eventually into heavy downpours. As the day continued, I found myself increasingly active in rescue operations alongside other emergency responders and citizens alike.
Lessons of Harvey
Over the next several days, it became painfully obvious that the city was not prepared to handle a disaster of this magnitude. To be honest, I’m not sure any amount of planning could have prepared us for what was coming. The issues we faced were far greater than what our current systems of flood control and emergency services were capable of handling. Harvey should have been a lesson to us all, and should have reminded us that nature is always in control. This catastrophic event should have also acted as an incentive to repair long neglected drainage systems throughout the city, find ways to increase detention systems and adjust current infrastructure to accommodate future needs.
Street Flooding on May 7th
On the evening of May 7th, I again found myself in a significant flood event that brought back memories of Harvey. I experienced the street flooding that made traveling impossible, the flooding of homes and asking myself, `What has changed since Harvey?’ As I was wading through thigh-high water, I noticed that water simply did not seem to be draining. I would expect to see some indication of a current flowing into the storm drains, but I saw nothing. As the water receded it became apparent that our existing infrastructure could not support the rainfall amounts that fell on that day. Roadways in Houston are essentially part of our drainage systems and should be viewed as such. When debris, organic or otherwise, falls into the roadway our drainage system runs the risk of backing up. Then, back up leads to flooding.
Flooding a Multifaceted Problem
So what’s the point of this? Instead of looking at flooding as a singular issue, we should apply an objective view and find additional contributing factors that we can address through a more comprehensive proactive approach to flooding. Let’s look at flood control like a system and view everything as inter-related. Flooding involves more than just water, just as crime involves more than just an offender. Let’s look at what contributing factors are present in smaller flood events, just as much as we look at the conditions present in combating the catastrophic events.
Contributing Factors to Street Flooding
In looking at the small rain events, we need to ask where our storm-drain backups come from. The answer might be more simplistic than we think. How often do we drive down a street in Kingwood and go to make a turn, only to be forced to creep out so we can see on-coming traffic? When was the last time you drove down the road and saw a dead tree toppled over or a yard crew blowing lawn clippings into a drain? Most importantly, prior to the May 7thfloods, when was the last time anyone of us saw basic service or maintenance being done to any of our rain water sewer systems?
Recommendations to Help Reduce Flooding
The catastrophic flooding that hit Kingwood during Harvey must be addressed by: adding gates to the dam on Lake Houston; dredging the river and mouth bar; and adding detention basins.
I cannot help but wonder, however, about the condition of our drainage systems in this city. Are our drainage systems working as intended and designed? It has recently come to light that our sewage systems are in such poor condition that they are leaking raw sewage, leading to a consent decree that will ultimately cost the taxpayers around $2 billion. I question if our sewage lines are clogged or cracked, why should we not at least consider the possibility that our drainage system may be too?
We need to address the major issues: gates for Lake Houston, dredging of the lake, and additional detention basins. The gates will allow for greater water flow, the dredging allows for proper conveyance and additional detention basins will help control run off and allow for our homes to stay dry during major flooding events. With that however, we must also focus ensuring our drainage systems work as intended. This can be accomplished through regular and routine maintenance.
Need Greater Emphasis on Infrastructure, Maintenance
We need to face reality and that reality is that, for too long, we have ignored and neglected the infrastructure in this city. We need to ask if the lack of investment into our infrastructure has led to a greater risk of flooding. We need to focus on addressing those areas of neglect that have been allowed to increase the potential of significant flood events.
We need to focus on the neglect that impacts our ability to effectively and efficiently respond to significant flood events. We need to focus on keeping our medians and storm drains free from obstructions and ensure that proper and regular service is being given to the system that is designed to keep us dry.

These developments confirm speculation that the Corps “backed into” the 500,000 cubic yard number for reasons unrelated to Harvey. Mystery still surrounds how they arrived at that number. The Corps refused to release many documents related to their decision. A review of their 4-page analysis obtained from the City found numerous issues, logical flaws, and questionable assumptions – uncharacteristic of the Corps.
Next Steps
With the year-long dredging program now almost complete and perhaps less than a quarter of the sediment removed that is required to restore the natural flow of the river, what will happen next? We have some hope.
Your Help Is Needed
However, to make that money stretch far enough to finish the job, we will need FEMA and the Corps to designate the remaining sediment as Category A.
