Second Dredge Reaches Start Point at River Grove Park

Dredge #2 has moved down the West Fork of the San Jacinto River to River Grove Park, the western limit of the U.S. Army Corps of Engineers Emergency Dredging Project.

An aerial view of the starting point at River Grove Park for Dredge #2; photo taken 9/14/2017.

At River Grove, the second dredge, which is owned by Great Lakes Dredge & Dock, the primary contractor, will cut a 150-foot-wide opening in the giant sand bar above that blocks the drainage ditch. That ditch empties the western third of Kingwood. Approximately 650 homes flooded above this blockage. The opening should allow the drainage ditch to flow directly into the river again. It will also let boaters use the launch at the park.

Ugly Photo, Beautiful Sight

Dredge #2 has reached its starting point at River Grove Park. It should begin dredging in the next day or so once pipe reaches Placement Area 2. Here, the dredge is seen behind the 10-12 foot high “side bar” seen in the first photo above. Foliage in the foreground has grown since the first photo was taken shortly after Harvey.

Plans for the 150-foot-wide path through the giant sand bar.

Second Dredge Will Start This Week

Even though the dredge has moved into position, it has not yet started dredging. The dredge pipe that will carry sediment is still several thousand feet short of an old sand mine, Placement Area #2 on Sorters Road south of Kingwood College.

The second dredge will begin working after pipe reaches the old mine.

Sediment in the West Fork has made it difficult to float the pipe upstream. Mechanical dredges have had to cut a path through the sediment, which has reduced the river’s depth to one foot or less in places.

Easterly Direction for Dredging

Both dredges will work in a downstream direction until they complete their respective portions of the river.

That is because the river is so shallow. Dredge #1 reportedly bottomed out five times on its way to its starting point between Kingwood Greens and King’s Lake Estates. Mechanical dredges also had to clear a path for it. Starting west and working east reduces the amount of time it takes for each dredge to get to its starting point.

By completion of the project, expected around April 1 next year, West Fork channel conveyance between River Grove and Chimichurri’s should be restored to pre-Harvey conditions.

Meanwhile, Officials Continue to Plan Phase II

Between now and then, the City, County and State will work with FEMA and the U.S. Army Corps of Engineers to plan and launch Phase II of the dredging. Phase II would include the mouth bar area. Details yet to be worked out include an environmental survey and identification of a placement area for the spoils.

As of this morning, Houston City Council Member Dave Martin was confident that both could be accomplished and that the mouth-bar dredging could be approved before the current project is done. If so, that would save taxpayers $17 million on mobilization and demobilization costs for a second, separate job.

New Difference Map Confirms Buildup of West Fork Sediment Around Mouth Bar, Underscores Need for Removal

A new “difference map” published by the Texas Water Development Board (TWDB) shows the rapid build up of sediment in the West Fork of the San Jacinto River where it meets Lake Houston. Difference maps show changes in sediment levels over time.

When Stephen Costello, Chief Resiliency Officer for the City of Houston, presented this map at the Kingwood Town Hall Meeting on October 9, it was to describe three potential phases of West Fork dredging..

Having had several days to review and discuss this map, several other things became clear. See the map and legend below.

West Fork Difference Map. Brown/red/orange/yellow/green areas represent decreases in sediment since last survey. Blue, violet, pink and white represent increases.

Conclusion #1:

The worst sediment buildup in the West Fork is near the mouth…exactly where retired Lake-Houston-area  geologists Tim Garfield and RD Kissling said it was when they raised the alarm about the mouth bar month’s ago.

Conclusion #2:

The problem is much worse than even they suspected. This clearly shows the extent of the West Fork’s mouth bar.  Like an iceberg, the part you see above water is only a small part of the bigger picture.  Vast new sediment deposits extend down to FM1960.

Conclusion #3:

Even Harvey-strength currents could not cut through the mouth bar. Therefore, smaller floods won’t be able to either.

Conclusion #4:

The mouth bar creates a sediment dam in the river that will exacerbate flooding. If the mouth bar area is not dredged, it will cause higher-than-normal flooding on smaller-than-normal rainfall.

Google Earth shows that the area between the mouth bar and FM1960 comprises 1700 acres. According to the difference map, this area received an average of approximately 2 feet of sediment. This means the channel and lake lost 3400 acre feet of capacity in this area.

Conclusion #5:

The mouth bar must be removed immediately. It and adjacent shoal areas get higher with every passing day and storm as water becomes shallower. If the mouth bar is left in place, it will slow the river, causing the area upstream (that is now being dredged) to fill more rapidly than normal with sediment.

Difference Map Proves Mouth Bar Must Go NOW

The mouth-bar area was the focus of the Corps’ survey efforts. They have known for months that it is the major problem. As they stated in Galveston at a meeting I attended, it is the primary driver for backwater and upstream flooding. Their value engineering report also states that in the event of another heavy rainfall, there is a “near certain likelihood” that wide-spread flooding will occur impacting even more homes than before Harvey, due to the river’s inability to pass high volumes of water. See Page 2 for the words engineers almost never use without cause.

We’ve been lucky so far this hurricane season. But minor floods earlier this year on March 28/29 and July 4 proved how serious this problem is. Had the City not lowered the level of Lake Houston for July 4, homes almost certainly would have flooded according to Houston City Council Member Dave Martin.

This Week’s Holdups

At a meeting in Austin last week, the City, Army Corps, FEMA, County and State of Texas all agreed in principle that the mouth bar needs to be removed. Further, if it can be added to the current dredging project, taxpayers can likely save $17 million or more in mobilization fees for a second, separate project at a later date.

Only two hurdles remain: a disposal site for the dredged material and an environmental survey.

A large disposal site is already under review that is much closer to the area of concern than either of the two current sites.

The proposed disposal site’s proximity could save taxpayers tens of millions of dollars more.

However, the environmental survey could delay the project beyond April when current dredging is expected to finish. If so, that could also increase flood risk.

Trees on the mouth bar initially led the Corps to exclude the bar from dredging for two reasons: one was environmental, the other legal. According to the Stafford Act, the enabling legislation for FEMA, FEMA funds cannot be spent to fix things that existed before Harvey. The existence of the trees proved that at least part of the mouth bar existed before Harvey.

The “Mouth Bar.” Note the trees on the right end.

Let’s Get Real

If the trees on the island raise an environmental concern, leave the part of the island that existed pre-Harvey. Dredge the channel and other parts of the island first.

This area includes 3-5+ft of Harvey derived sediment which should qualify for FEMA disaster recovery funds under the Stafford Act based on the new TWDB map.

The longer we wait to dredge this island, the more vegetation will grow on it, the more resistant to erosion it will be, and the more expensive it will be to dredge.

Are the Army Corps and FEMA trying to save an invasive species that USDA wants to eradicate?

Close examination from a boat showed the trees in question to be Chinese tallow trees, an invasive species that the USDA has been trying to eradicate from here to Florida. It’s actually poisonous to local animals. If this tree costs taxpayers tens of millions of dollars in delays and opportunity costs, it will become the new poster child for government waste and folly…especially if Humble, Kingwood and Atascocita flood in the meantime. This is one delay I certainly wouldn’t want my name associated with. That’s the wrong way to go down in history.

This tree on the mouth bar which initially caused the Army Corps to exclude the bar from dredging is a Chinese tallow, an invasive species which the USDA is trying to eradicate. Note the heart-shaped, aspen-like leaves – the tell-tale identifier.

Harvey Experiences of Robert Westover and Pat Klemz at Kingwood Village Estates  

Harvey’s floodwaters at Kingwood Village Estates in the heart of Kingwood, 1.4 miles from the San Jacinto River

Interviewed by Bob Rehak:

In 50 years of professional writing, this is the hardest story I have ever written. Twelve people died. Seniors. People like me. Had they evacuated sooner, many might still be alive. But there was no warning until water started creeping under the doors of Kingwood Village Estates at 3 a.m., on August 29th, 2017.

Kingwood Village Estates is a gorgeous retirement community in the heart of Kingwood. It contains 120 condominiums and a clubhouse nestled around tranquil, tree-lined streets.

Today, a casual observer would never know Kingwood Village Estates flooded. 

Residents range in age from 65 to 95. Some have lived there 20 years. That’s remarkable given the age of residents. Many are widowed. Many have impairments. But all still live independently … with help from each other. It’s a tight-knit community.

Robert Westover is the property manager. Pat Klemz, at 65, is the youngest resident and president of the condo association. This is the story of how they got more than 75 people out alive during Harvey. Sadly, it’s also the story of how twelve later died of injuries sustained during the surprise evacuation or the stress that followed.

The Day Before the Flood

Rehak: “Tell me about the day before the evacuation.”

Westover: “We had never flooded before. The day before they opened the gates at the Lake Conroe Dam, we felt like we could manage. The drains were clear. The streets were clear. There were no evacuation warnings. However, we did encourage people to move to higher ground just to be safe and some left to stay with their families. Then at 3 a.m. the next morning, water began crawling up the staircases. The fire department came in and said, ‘You have to leave.’”

Rehak: “What was their concern?”

Westover: “Electricity. Fear of electrocution. We started waking people up and they carried them out mostly by airboats brought in by the Cajun navy. We evacuated 75 to 80 people who were still here. Every first-floor unit flooded.”

“Water Rising Right Before Our Eyes”

Klemz: “I got a phone call early in the morning of August 29th while I was still sleeping. One of our buildings already had four or five inches of water. It just kept coming. You could see it rising right in front of your eyes; it was that fast. I got another person and we went door to door waking people up. Some people didn’t want to leave. All we had to do was ask them to look out of the window. When they did, everybody cooperated. We sent them upstairs first.”

Lobby of Windsor House at Kingwood Village Estates today after flood repairs. Residents waited at the top of these stairs to be rescued by boats the night of the flood.

Westover: “The elevators had been knocked out by then. No electricity. Everything was dark. Some people couldn’t get upstairs by themselves, so we had to help them.”

Rescue Boats Came Through Front Doors

Klemz: “It took two or three hours for first responders to get here. They literally had to break down doors to float their boats into our lobbies.”

In the dark, early hours of August 29, 2017, rescuers broke down these doors to rescue people with airboats.

“I did triage at the top of the stairs, while Kay Lake, another resident (age 68), went around with first responders to make sure everyone was out. They also had to break down the doors of some units. Some people simply refused to open their doors. They were scared and didn’t want to leave.”

“Most left only with the clothes on their backs. Many people had pets. Some forgot their identification. Some forgot their medicines. And some had to be carried down the stairs in wheelchairs. It was frantic. But when it came to loading boats, everybody cooperated fantastically. We had to balance the boats to make sure they didn’t tip.”

Evacuating In Darkness

Westover: “All this happened in darkness. It was a couple hours before the sun came up. It only took four or five hours for the water to go from the gate to the highest building. The flooding started at 3 a.m. By 5 a.m., we already had four or five inches of water everywhere. The water didn’t stop rising until it reached Wendy’s about three quarters of a mile up the road. Ultimately, we had to rip out sheetrock to the top of door frames.”

“No One Died that Night, but…”

Klemz: “No one died that night, thank God.”

Westover: “However, by the end of the year, 12 of our residents died. The flood and the stress were just too much for them to go through.”

Rehak: “What was the most poignant story from that night?”

Klemz: One man in the early stages of Alzheimer’s was also afraid of heights. His wife came up to me and said, “I don’t know if he’ll make it down the stairs.” So I sat with him for about ten minutes and just talked with him. When first responders came to pick up his wheelchair, I walked down the stairs next to him.”

Westover: “His wife said, ‘He wouldn’t have made it out of the building had it not been for Pat.” He was diabetic. Had lots of problems. He went into the hospital. Came out. Went back in.”

Klemz: “Sadly, he passed two months later. There are so many memories like that from that night. I had one woman who came up to me after we moved back in. She said, ‘You saved my life.’”

At this point, Klemz’ eyes turn bleary and she chokes back tears. “She said if I hadn’t been there to talk her down the stairs, she wouldn’t have been able to get down. She told me, ‘You saved my life.’”

Memory Loss, Short Tempers, Symptoms of PTSD

Klemz: “This was extremely stressful for anyone, but especially for older people. Many didn’t even know whether their families were safe; cell phones weren’t working. They were shuffled from shelter to shelter or taken in by strangers.”

“Later, many would come up and tell me, “I’m having a terrible time with my memory; I’m short tempered; things like that. I saw the same symptoms after Katrina. Most in their seventies and eighties never expected to go through something like this.”

Rehak: “What kind of symptoms?”

Klemz: “People are distracted. They can’t concentrate. They anger easily. They can’t sleep. They become agitated every time it rains. The stress is overwhelming. People in their eighties lost homes and all their belongings. Some people were so traumatized they couldn’t remember their names.”

Rehak: “What triggers the PTSD?”

Klemz: “Rainstorms set people off. Also, if you feel like you’re not in control, you more easily lose your temper. People lost that sense of control; they couldn’t stay. Even when the water went down, there was nothing around us. Toilets would not work. Everything was backed up. There were: no alarm systems, no doors on the first floor, no elevators, spotty electricity. We didn’t get electricity back completely till the third week of December!”

12 Deaths Attributed to Injuries and Stress

Rehak: “Tell me about the people who died? How was their health before the evacuation?”

Westover: “They were generally in good health, but fragile in the sense of hips, knees and that kind of thing. Six died within 30 days. They were on the staircase being handed down into a boat. Of the six, one was male; the rest were female. All were in their eighties.”

“Six more died within six months – we think from the stress of not being able to come back to their homes. We lost 12 altogether from injuries directly related to the event or from the stress that resulted from it.”

Rehak: “How does that compare to the normal mortality rate for people in this age group?”

Westover: “Normally, we might lose one or two folks a year. Twelve in six months is highly unusual.”

Lack of Warning

Rehak: What was the most terrifying part of the experience?”

Klemz: “When my phone rang at 5 a.m.”

Westover: “Monday everything was fine. We were totally unprepared for Tuesday. There was no warning whatsoever of what would happen when Lake Conroe opened its gates.”

Klemz: “Harvey was diminishing at that point. There was no indication so much water was going to come down the West Fork. That’s why most people didn’t evacuate. If they had said Monday night that so much water was coming, people would have been out of here.”

Rehak: “What was the best part of the experience?”

Both: “Getting everybody out alive.”

A Second Miracle

Westover: “The repairs were our second miracle.”

Rehak: “How so?”

Westover: “Because of the ownership structure, no banks would loan us money. They were concerned about our ability to pull everyone together and rehab the place. Residents own their own units. They also own a percentage of the common areas proportional to the size of their units. We had to rehab 64,000 square feet at a cost of $3.5 million. Every penny of that came from the owners.

Less than 5% had flood insurance and most are widows. People had to come up with $20,000 to $50,000 depending on the size of their condo. It was amazing how folks came together. They found a way to finance repairs and wrote a check. If that hadn’t happened, it would have affected all of Kingwood.”

Kingwood Village Estates today. 

“Ninety percent of the owners are back in their units now. The rest should be back in their units soon. They like it here. They miss it.”

Rehak: “How did you manage? Your personal home was flooded, too!”

Westover (choking up): “One day at a time.”
