4/7/25 – Last Saturday, 2.5 inches of rain turned the Meritage construction site in Atascocita into Lake Meritage. But by this morning, contractors were draining Lake Meritage into a City of Houston storm sewer.
Close examination of aerial photos shows a series of trenches cut under silt fences to let the water drain from the site quickly and bypass the usually slow filtration process that the fences provide.
Contractors had also cut a series of trenches within the site to move trapped stormwater toward the street. And an excavator was scooping muddy stormwater from the beginnings of a detention basin into yet another trench that led toward the exit rows.

Where did all the water go?
Interior channels brought the stormwater toward the street…The excavator (center left) was scooping buckets of water out of the detention basin and dumping it into another channel that led toward the street.…and a series of shovel-wide trenches let water leak out from under the silt fence.
Much of the muck flowed through a roadside swale to a storm sewer inlet. See below.

But not all of the muck stayed in the swale. The next ten-second video shows part of it running down the street. There was so much at one point that contractors had to partially block it off.
Another 10-second video showing stormwater entering street. Supplied by passing motorist.
Motorist tracks overflowing silty stormwater down street for another 18 seconds until it flows into City storm sewer inlet.
When I drove by about an hour after the last video was shot, the flow through the street had ended and someone had installed a screen over the inlet that’s clearly not on the video. The screen could make them appear compliant with their Stormwater Pollution Protection Plan.
Silt Fence Repairs Not a Priority
Unfortunately, the contractors did not drain the water invading neighbors’ yards. And repairing damaged silt fences that protected neighbors from the muck was not their highest priority.

4/6/2025 – After a little more than two inches of rain in a two hour period on 4/5/25, neighbors of the Meritage development in Atascocita bordering Pinehurst Trail Drive began noticing muddy runoff creeping toward their foundations.
Aerial photos taken today show that Meritage and its contractors have made some improvements to control runoff since previous storms. However, the attempts did not protect neighbors’ property during this storm, most likely because of poor execution and slow construction progress.
Failures Illustrate Need to Complete Drainage Work Faster
In Phase I, Meritage still has yet to install drainage and silt fence in areas it clearcut early in 2024.
In Phase II, dirt pushed silt fencing over in places. Muddy runoff invaded neighbors’ yards. Silty water also flooded Pinehurst Trail Drive.
These failures illustrate the need to complete drainage work faster once land is cleared.
Meritage is creating the same issues for its neighbors in Atascocita that the Perry Homes Woodridge Village development did with its neighbors in Kingwood.
Construction, in general, increases flood risk. For neighbors when construction practices are flawed or incomplete. And for larger, surrounding areas when increases in impervious cover may be insufficiently mitigated.
One-Year Rain Overcame Meritage Efforts
Before looking at photos of yesterday’s rain and its aftermath, let’s look at the rainfall totals. The closest Harris County Flood Control District gage is at West Lake Houston Parkway, a little more than a mile north. It received 2.6 inches of rain in a two-hour period on Saturday.
From Harris County Flood Warning System gage on West Lake Houston Parkway at West Fork.
That’s a one- to two-year rain according to NOAA’s precipitation-frequency estimates for this area. See the 2-hour row in Columns 1 and 2 below.
Atlas 14 Rainfall Probability Statistics for Lake Houston Area
It may have rained intensely yesterday. But the rain did not come close to setting any records. It’s EXPECTED. Statistically, construction companies should PLAN on encountering such rainfalls on virtually EVERY project of this scale.
But yesterday’s experience shows they don’t. At least Meritage and its contractor(s) didn’t.
Attempts to Control Drainage Fall Short
Meritage broke this project up into two phases on opposite sides of Pinehurst Trail Drive.
Contractors finished clearing Phase I on the west by the end of January 2024.
They finished clearing Phase II on the east by early 2025.
They added more silt fencing, staked out wattle rolls to help filter runoff, and built berms in places to help protect neighbors. They also placed sand bags next to storm sewer entrances to help stop sediment before it escaped into storm sewers.
But photos and video taken after yesterday’s rain also show:
In Phase I:
Severe erosion
Storm sewers and drainage pipes stacked and waiting for installation
No silt fencing protecting wetlands
No paving, no visible progress toward completion in months.
In Phase II:
Dirt pushed up against silt fences, knocking them over
Silty stormwater in neighbor’s yards near the damaged silt fence
Ponding water throughout the site
Runoff closing off half of Pinehurst Trail Drive.
See below.
Video and Photos From Day of Storm
A reader sent me these two clips. The first shows street flooding caused by runoff from Phase II. The second shows flooding in the Phase II site itself.

Personally, I hoped for more – especially from a company whose advertising slogan includes the words “Built. Better.” Construction opens a window of vulnerability to flooding. Companies should do everything they can to complete drainage work as fast as they can to close that window.

12/7/24 – One of the leading environmental groups in the Houston region is the Bayou Land Conservancy (BLC). Their motto: “We preserve land along streams for flood control, clean water, and wildlife.”
Last year, BLC volunteers logged thousands of hours maintaining and improving natural areas and trails that help others appreciate nature’s wonders.
One such volunteer is Jeff Hodges. He helped restore land along Spring Creek in BLC’s Arrowwood Preserve, which is being used for environmental education. His story is a testament to the tenacity of BLC volunteers in their service of nature.Below are excepts from Hodges’ responses to my questions.
Preserve’s Contribution to Flood Reduction
Rehak: How does the Bayou Land Conservancy help reduce flooding?
Hodges: Development in the Houston area will continue. We need to understand how this can lead to increased flood risk of flooding if not managed correctly.
BLC is a land trust. It protects lands where rain water is absorbed and held as flood waters, slowing down the release of water into creeks, streams and rivers. That helps reduce or eliminate flooding downstream.
These lands are increasingly important. They let water soak into the land providing much needed water, to the water table and aquifers.
Currently, ever major aquifer in the U.S. is being depleted, except in the Pacific Northwest. This depletion contributes to subsidence, which increases flood risk. Areas in the Woodlands have lost two feet of elevation from subsidence.
The lands that BLC protects also provide habitat for wildlife and give people a chance to enjoy nature.
Rehak: Specifically, how does Arrowwood reduce flooding along Spring Creek.
Hodges: Arrowwood is a natural flood plain. It slows and stores rainwater flowing toward Spring Creek. A large portion of the preserve floods in heavy rains. It gives stormwater someplace to sit and wait instead of moving quickly downstream and flooding other areas already developed.
Restoring the Natural Environment
Rehak: I hear that in trying to make Arrowwood more user friendly, you and your fellow volunteers removed more than a mile of silt fence. How did it get there?
Hodges: A sand-and-gravel company installed the silt fence when it applied for a permit to turn the property into a quarry. But neighbors blocked approval of the permit. The mining company, after a number of years, donated the land to Bayou Land Conservancy.
Rehak: Removing that silt fence must have been a chore!
Hodges: We actually made a short movie about it. The preserve comprises 117 acres and the fence surrounded 22 acres. As work began to make the preserve accessible, we realized that we did not have the correct equipment to remove the silt fence.
Bayou Land Conservancy Volunteer Jeff Hodges led the Arrowwood Silt Fence Removal Project
We originally estimated the preserve had 2 miles of silt fencing containing approximately 700 posts, each weighing 5 pounds.
Jeff Hodges
The task seemed overwhelming. But we were very concerned about the impact of the fence on wildlife. Turtles and other small wildlife couldn’t get over or around it.
Volunteers Discover Task is Herculean
Rehak: What kind of problems did you encounter?
Hodges: I started to wonder if we could remove the silt fence manually. Bayou Land Conservancy gave me and a small team permission to work on it. The first day, two of us tried to develop a process to remove the silt fencing. In a half day, we could only remove about 10 posts and 50 feet of fencing.
Most of the posts had to be dug out by hand. Each was four feet and originally pounded into the ground to a depth of two feet. But over time, silt built up around the fence. Many sections were totally buried.
The silt fencing has three components: posts, heavy metal fencing, and a plastic tarp. The combination prevents silt, sand and rocks from washing into the creek.
After the first day, most people would have been discouraged. But our volunteers proved it could be done. It was just going to take a lot of time and effort.
Volunteers decided to separate the fence and post removal operations to speed things up.
We decided we would remove the metal fence along with the black tarp first. We left the posts until we were able to develop a better way to remove them.
But the removal of the fencing was not without problems. Portions of the fencing were buried, so we had to dig them out. Worse, the fencing had become overgrown. Before we could remove it, we first had to remove fallen trees, and cut away vines and brambles.
Triumph of Ingenuity, Sweat and Safety Goggles
Rehak: Did you ever develop a faster system?
Hodges: As we removed fencing over the next couple of months, we worked on developing a technique to remove posts without digging. Eventually, we developed a technique that sped up the operation. We hit the posts with a sledge hammer on all four sides to loosen them. Then we hooked up a farm jack to pry them out of the ground.
Working as a team, we could remove about 15 posts per hour. Some, buried to the top in heavy clay, still had to be dug out by hand. Those just took longer.
Everyone working on this project had to wear long pants, long sleeves, safety glasses, and heavy-duty work gloves. We also had to be up to date on our tetanus shots, too for obvious reasons.
Rehak: What did the final boxscore say?
Hodges: All in all, the team ended up removing 499 posts and more than 1.5 miles of fencing. While working on the fencing, we also removed trash and litter which seemed to be everywhere. Fencing and trash filled two industrial dumpsters.
Some of the trash and fencing materials removed from the BLC Arrowwood Preserve.
It was grueling work. But the transformation of the land is overwhelming. And very satisfying. The beauty of what this preserve will become is now evident.
Postscript: Jill Boullion, Bayou Land Conservancy Executive Director, said, ““Jeff was awarded our Trailblazer Award for 2024 because of his leadership on this project. It’s an important part of our restoration plan for Arrowwood that will make the preserve even more ecologically valuable for the community. We appreciate volunteers like Jeff and the crew that did this very difficult project.”

Improving building codes to mandate higher home elevations
Requiring greater setbacks from rivers, streams and bayous
De-snagging to prevent log-jams from backing water up
Preserving wetlands, grasslands and forests to absorb and slow runoff, and to create recreational opportunities for nearby homeowners
Bio-swales and ditches to create more stormwater storage and positive drainage around homes
Buying out flood-prone homes and converting the property to recreational or flood-mitigation space.
I’m sure more techniques exist. But those represent the big categories.
Complex Decisions Involving Many Factors
No one tool works for all situations. And many of the tools that reduce flood risk fly in the face of other human values. They may conflict with other values beyond safety, that we hold dear. Consider, for instance, property rights, individual freedom, job formation, expanding the tax base, a desire to live near water, and risk-taking.
So how do professionals decide which tools to apply where and when?
Again, it depends on a number of factors. To name a few:
Is State or Federal disaster-mitigation aid available?
Is Disaster Relief aid available?
Homeowner Inquiry Prompted Exploration
A homeowner reacted to one of my posts today. She lives in a low-lying area near FM1485 and the San Jacinto East Fork. It flooded badly on May2, 2024. She was certain that dredging and tree removal from the East Fork would help. But after investigating the area online, then from the ground and air, I wasn’t sure.
The normal river elevation in that area is 47.25 feet.
But on May 2, the river rose to 77.4 feet – 17 feet above the top of the river banks and 30 feet above normal!
Jeff Lindner, Harris County Meteorologist, had this to say about the May flood. “Since 1994, this was the second highest crest of the river at FM 1485. It exceeded Tropical Storm Imelda by 4.0 ft and the October 1994 flood by 1.0 ft.”
Lindner continued, “The flood of record remains Harvey which was 4.0 ft higher than the May 2024 event. The river exceeded the .2% (500-yr) exceedance probability elevation at the FM 1485 bridge by 1.5 ft. The table below shows the top five highest peaks on the East Fork of the San Jacinto River since 1994 at that location.”
Residents in this neighborhood experienced five 100-year-or-greater floods in 20 years. That’s one every four years. Is the risk 1% or 25% per year?
See the FEMA floodplain map below for the area in question.
It shows you how difficult flood prediction can be. It also shows you why even nature lovers should give water in Texas a wide berth unless they are prepared to lose everything. The May flood wasn’t even related to a tropical event!
Yellow/green diagonal line is the Harris/Montgomery County line. Image shows neighborhood S of FM1485 near East Fork. Crosshatch=floodway, Aqua=100-year and Tan=500 year floodplain.
Unfortunately, most of the homes in this neighborhood didn’t look like people could afford to lose everything. And I saw several that had been totally obliterated along with two roads that washed out.
I’m not sure what this was. But it was the only structure semi-standing for blocks around.
Professionals Say Buyouts Best Option In This Case, But…
In an area like this, flood-mitigation professionals have few good options. Given the depth of flooding, three professionals told me that intervention would have to be on a massive and costly scale to make a difference. As a result, each suggested buyouts as the best, most cost-effective alternative in this area.
Shortly after the May event, I interviewed a young couple named Daniel and Kathleen Moore. They lived on some of the highest land in the subdivision, but had flooded three times in the seven years that they owned their home (Harvey, Imelda, and May 2024).
They were hoping for a buyout. I called again today to see if they succeeded, but they were selling their property and moving out of state with their new baby. Why?
While Daniel was restoring the home, someone burned it to the ground on July 28th. Nothing stands there now but a charred chimney.
This was a heartbreaking story that deeply affected me personally. I once lived in a home near a creek that flooded frequently when I had two young babies.
While buyouts may sometimes be the most cost-effective option, they are not easy, according to a County Emergency Management Director that I interviewed. Counties must apply for FEMA buyout money and then it can take years to evaluate and rank all the applications and distribute the money.
Forest Cove buyouts took five years after Harvey to complete.
Ironically, the fact that the Moore’s were in a 500-year floodplain may have hurt their buyout chances. FEMA likes money to go to homes that are insured but which flood frequently.
So What About Dredging and Tree Removal?
The Moore’s lived in Montgomery County. But the other family that contacted me lived on the Harris side of the county line in the same neighborhood.
Typical scene in East Fork south of FM1485Area has trees down everywhere.
Experts I talked to suggested dredging wouldn’t make an appreciable difference given the narrow width of the river channel and the height of flooding. Plus, it could undermine more trees along the heavily wooded banks.
Removing trees that have already fallen, they say, is a good idea. They could float downstream, form log dams that flood other homes, and/or harm boaters in Lake Houston. But who is responsible for removing them?
I asked Matt Barrett, head of SJRA’s Flood Management Division. Said Barrett, “SJRA’s jurisdiction does not include Harris County, so projects constructed in Harris County would have to be led by HCFCD.”
Distant Chances for Other Flood Mitigation
That said, Barrett also volunteered that SJRA has partnerships with both HCFCD and the City of Houston. The entities work together on multiple projects from the San Jacinto River Basin Master Drainage Plan. But finding funding remains a challenge. And large scale projects are not quick to implement.
That brings us full circle to the original question in the headline. What was or is the best thing(s) homeowners can do to reduce their flooding chances? In my opinion:
Avoid buying property near water if you have a flooding concern
I’m not a professional engineer and I do not render professional engineering opinions. But I have interviewed a lot of flood victims who wish they could turn back the hands of time and build on higher ground.
Foundation being endangered by riverbank erosion.
If you have the slightest qualms about flooding when purchasing property, make sure you consult a professional engineer to evaluate your risk and mitigation options.

8/10/2024 – Sometimes Randy Reagan must feel that he has struggled for most of his adult life against rising floodwaters, sand mines and the San Jacinto River Authority (SJRA). He has flooded six times in the last nine years. Still, he’s rebuilding on a lot he bought 30 years ago. But he’s doing it differently this time.
May 2024 Flood. Reagan property in background. Note roof of submerged vehicle in foreground.
Erosion of Country Lifestyle
Reagan grew up not far from the San Jacinto West Fork. He remembers a time as a child before Lake Conroe when the river ran clear and teemed with fish.
His wife grew up in the same neighborhood. Her parents were the first settlers in an area that came to be known as Bennett Estates between FM1314 and the San Jacinto West Fork.
They loved living near the river and all the abundant wildlife. So Reagan bought 5.5 acres for $10,000 back in the mid-’90s. He put a mobile home on it and started raising a family. He hunted all the meat his family ate from his own property and the surrounding forests. Life was good.
The 1994 flood was the highest ever in that area. The SJRA released 56,000 cubic feet per second (CFS) from Lake Conroe during the storm. So Reagan elevated his home a foot above the high water mark from that storm and figured he was safe.
But gradually, his dream of peaceful, country living turned sour. In the mid-2000s, two companies started mining sand near his home – one a few blocks north, the other immediately south of his property.
The mines accelerated runoff and erosion. They also changed local drainage patterns in ways that flooded his property.
In the meantime, upstream areas grew, also increasing runoff. And by the time I first met Reagan in early 2020, his property had flooded five times in four years. The worst: Harvey in 2017. Ninety-three inches of water invaded his home. That’s almost 8 feet! See that story here.
Eventually, Reagan tore down the mobil home. Repeat flooding had caused the foundation to shift and destabilized it. He and his wife began living in his workshop or with relatives.
Reagan tried to get a low-interest SBA loan through FEMA to rebuild. But they denied him because he had “let his flood insurance lapse after Harvey.”
“Of course I let it lapse,” said Reagan. “There was nothing left to insure. The home was gone.”
Fast Forward Four Years
The May flood this year swamped his property again after the SJRA opened the gates on Lake Conroe and began releasing 72,000 CFS, the second highest release rate in SJRA history.
Reagan points to high water mark on his shop from May 2024 flood – 52 inches.
Only Harvey exceeded that rate. SJRA released 79,000 CFS in 2017 during Harvey.
Since then, Reagan began planning his comeback against Mother Nature, the sand mines and SJRA.
His dream now is to build a foundation for a new home up 10 feet above the original level of the land. That would make the land higher than the Harvey high-water mark.
Then he wants to build a new home up on stilts, another ten feet above the elevated foundation. It would be elevated 20 feet above his first home on the property and more than 10 feet above Harvey. Hopefully, that will keep him safe for a few years.
The retired oil-field worker and bull rider is looking at designs from UB Homes. He also hired a MoCo excavation company, Graham Land Services, to excavate a pond at the back of the property.
Dirt from pond excavation (background) is being used to build up home pad (foreground).
Dirt from the pond is building up the foundation where his new home will go.
Pros and Cons of Rebuilding in Location that Floods
On the plus side:
Mining behind his property has ceased. He now has a 42-acre pond behind him. No one will ever build behind him and spoil his view.
He can still hunt on his property.
Despite the flooding, property values have appreciated. Not far away, a home recently went up for sale at $1.4 million.
Development in surrounding areas has brought shopping, services and hospitals closer to home without changing his country-living atmosphere.
The May flood deposited fish in Reagan’s pond, which are now thriving.

On the minus side:
All the tractor work has taken a toll on Reagan’s aging body. He complains of aching joints and bulging disks in his back and neck. He’s also fighting knee and shoulder pain from a lifetime of backbreaking work in the oil fields and on his property.
He wishes SJRA would pre-release water from Lake Conroe at much slower rates in advance of major storms, but has little hope that they will. “This May flood could have been totally avoided if they would have let water out sooner,” said Reagan. “SJRA needs to start operating the Lake Conroe Dam a lot better than what they’re doing.”
Reagan feels SJRA places Lake Conroe recreation above the protection of downstream property.
He feels he would have to move north of Huntsville to find the kind of flood-safe country living he once enjoyed. “It’s hard to get a piece of country living anymore in Montgomery County. It’s all going away,” said Reagan.
A Pioneer Spirit
Reagan typifies the struggle many Houstonians feel. He loves nature and living near water – until floods exact their terrible price. Still, he returns. To fight for a life he loves.
Reagan takes a break from moving in front of the property being raised for a new home.
I admire the fact that he’s not waiting for others to protect him from the ravages of West Fork flooding. By elevating his property and home, he’s protecting himself and his family.

8/5/24 – Harris County Flood Control District (HCFCD) has released its final report on Hurricane Beryl. The amazingly detailed, fact-filled, 30-page report by Jeff Lindner, Harris County’s meteorologist, covers the storm’s origins, rainfall, storm surge, high-water marks, wind speeds, flooding, and more for locations throughout the County.
Every sentence contains nuggets of information that you can use to amaze your friends, relatives in other states, and insurance agents.
Wind Speeds Up to 99 MPH
I’m not joking about insurance agents. One homeowner told me an adjuster denied her claim based on the fact that the wind was “only 37 MPH.” This report shows both average wind speeds and gusts. According to the official report, peak gusts in the Lake Houston Area were 69 MPH – almost double what the adjuster said.
Kyle Field at Texas A&M recorded the highest gust – 99 MPH.
Highest Storm Surge since Ike
Have a home near the shore? You may be interested to know that Beryl produced the highest storm surge since Hurricane Ike in 2008.
Storm surge averaged 5-7 feet above ground level along the coast, near the west side of Galveston Bay, Clear Lake, and the lower San Jacinto.
Water levels at the ship-channel turning basin reached 9 feet above ground level.
The high surge levels are likely the result of freshwater descending in watersheds as wind drove seawater into the upper portions of the ship channel.
Rainfall Intensity
Rainfall intensity was very high in places at times.
The Houston Transtar Center in the Buffalo Bayou watershed received 9.9 inches in 6 hours. There’s only a 2% annual chance of that (meaning it was a 50-year rainfall at that location). Transtar also received the highest 24-hour total – 12 inches (a 4% annual chance or 25-year total).
Out of 193 gages, 82 (42%) recorded an inch of rainfall in 15 minutes.
Rainfall Totals
Rainfall totals were less impressive due largely to the speed of the storm.
Most of the county received 24-hour totals of 6-9 inches. Higher totals generally fell south of I-10.
Six-hour rainfall amounts averaged 4-7 inches across most of the county.
Rainfall rates on the Atlas 14 chart for both 6- and 12-hour periods generally fell between 2- and 10-year events.
24-Hour Rainfall Totals during Beryl. HCFCD report also contains totals from shorter time periods.
The report noted that storms before Beryl had left the ground highly saturated. That increased runoff.
Only 10 Homes in County Flooded
Channel flooding was moderate. Approximately 10 structures flooded throughout the county. All suffered flooding in the past. They were built in areas with very low elevations.
Forty out of 193 gages reached or exceeded “flooding-likely” levels. That means the channels were full to the top of their banks.
Had the storm moved slower, Beryl could have been a very different story!
2.26 million homes lost power – some for up to 11 days. The Lake Houston Area was among the hardest hit because of the dense forests here. The density adds a degree of difficult for both maintenance and repair crews.
Note uprooted tree to left of bend in trail still leaning over power lines in Kings Forest. Photo taken 8/4/24.
Twenty-eight days after the storm, dead trees and limbs still clog streets and lean on power lines.
Intense rainfall occasionally caused flooding of streets and roadways. Portions of SH288, I-10 and I-45 flooded and became impassable at times.
Beaches eroded along most of the upper Texas Coast. High tides and storm surge overtopped and destroyed entire dune systems.
Beryl also damaged coastal roadways, beach access walkways, and private as well as public properties.
High-Water Marks
A table on page 30 compares the high-water marks at dozens of locations with those from previous storms dating, in some cases, back to 1973.
At Clear Creek and I-45, Beryl flooding reached almost as high as Tropical Storm Allison (7.7 feet in Beryl vs. 7.8 feet in Allison).
HCFCD did not record any high-water marks in the Lake Houston Area.
Deaths
As of July 31, Hurricane Beryl had directly caused five deaths in Harris County: three from drowning, two from falling trees.
Additionally, the County recorded 13 indirect deaths: eight heat related, five recovery related.
The report notes that Beryl continues a recent trend of more fatalities occurring in the aftermath of landfalling storms than from the storms themselves.
I’m not quite sure what to infer from that. Is our preparation for flooding getting better? Or is our infrastructure maintenance getting worse?

8/3/24 – Yesterday was a start. Kingwood residents and political leaders met in several areas hard hit by Hurricane Beryl to discuss ways to improve recovery efforts. The idea: to start a dialog about steps that Houston Public Works, CenterPoint, community leaders, and residents can take together to reduce disruptions from future flooding and power outages.
Connectedness of Issues and Domino Effects
The recovery discussions took place on streets still clogged with debris that were near power line corridors, greenbelt trails, a school and two sewage “lift stations.”

Lift stations pump sewage uphill to treatment plants. When treatment plants are downhill, gravity does the work – a much more reliable solution. Without power, or when flooded, sewage from the lift stations can back up into people’s homes and overflow.
The City of Houston has hundreds of such lift stations. And during Beryl, Houston Public works shuttled backup generators back and forth between them. They tried to buy enough time to keep the lift stations from backing up and overflowing.
Unfortunately, the shuttling didn’t work in parts of Woodstream Village. There, residents talked about backed up sewage flowing from homes into streets and then Lake Houston.
Chris Kalman, Woodstream resident, talked about how problems are becoming progressively worse. “Centerpoint was awfully quiet when asked about repeated power outages in this area going on 18-plus years now. No real answer.”
The solution, according to a Public Works spokesperson Greg Eyerly, is to buy more generators. But that could take years in a city struggling with other urgent budget issues. And recovery can’t wait.

Preventing/Reducing Outages
Related recovery discussions about preventing or reducing power outages took place throughout the morning. According to the Federal Energy Regulatory Commission’s final 2004 report on Utility Vegetation Management, “tree touches” are generally cited as the single largest cause of electric power outages. They occur when trees, or portions of trees, grow or fall into overhead power lines.
In Kingwood, trees have grown up under or around power lines in many places. In fact, many residents have commented that if not for recent Beryl-related trimming, they would’t even have known power lines were there.
Trees touching power lines near Deerwood Elementary where group first gathered yesterday.Power to nearby residents was out for 9.5 days after Beryl.
Unfortunately, from a recovery/electric reliability point of view, Kingwood is in a region that experiences frequent high winds and heavy rainfall. The heavy rainfall supports fast growth of tall trees. And frequent high winds push those trees into power lines.
So another major focus of recovery discussions included:
CenterPoint vegetation management practices, especially maintenance intervals (which they avoided disclosing)
Trees that fall from trail association property onto CenterPoint power lines
Removal of debris that can clog storm sewers
Who is responsible for what
How one group’s performance or lack thereof can affect electric reliability and related issues for others.
Need for a New Approach Involving Trail and Community Associations
At-Large City Council Member Twila Carter said, “CenterPoint must have a collective conversation, resulting in a plan with KSA, the HOAs and Trail Associations to address maintenance. The thoughts of “In the past, that’s the way we’ve always done it,” or “the way it’s always been” no longer work for this community. We need to address the community as it is today, not how it was planned 50 years ago.”
District E City Council Member Fred Flickinger said, “A meeting between the trail associations and CenterPoint will make a significant difference. It was the best thing to come out of today.”
Flickinger was referring to a discussion with Dee Price, KSA President. Price agreed to set up a meeting with Kingwood trail associations, community associations, CenterPoint and the council members.
Flickinger continued, “There has to be significantly more aggressive vegetation management in the future.”
Kaaren Cambio, Dan Crenshaw’s assistant, explained how the homeowner and trail associations around Lake Conroe regularly inspect resident properties for trees and branches that threaten power lines. She said they send letters to residents requiring them to take down such trees or trim them back.
CenterPoint can trim back limbs and trees that encroach on their easements. But CenterPoint cannot take down trees on private property. That includes trail association property. So recovery needs to be a cooperative effort.
Chris Bloch, a long-time Bear Branch Trail Association (BBTA) Board Member, was not at the meeting, but observed, “The number of trees and limbs that fell during Beryl was easily 2X+ what we had during Ike. I attribute this to two summers of drought which stressed the trees and then an exceptionally wet spring.”
Costs of Burying Power Lines Not Clear
Flickinger also said, “I’m pushing for more underground electrical lines. I want to see the analysis of the costs. I know it’s expensive, but I believe we are paying for it incrementally every time there is a storm.” Flickinger cited lost wages, the cost of backup generators, debris cleanup, and more.
CenterPoint responded that the costs of burying wires are location specific and the costs of repairing underground cables, when cut, are much higher. However, CenterPoint offered no specifics about the cost of burying power lines in Kingwood.
Impacts on the Elderly and Ill
Cambio also talked extensively about the impact of power outages on hospitals plus nursing and retirement homes.
Many operate in multi-story buildings. Elderly in wheel chairs rely on elevators. But without power, they are trapped. They can’t get up or down stairs to get to doctors. Nor do they have power for dialysis, breathing machines, etc.
Kingwood Hospital had a backup generator. But, reportedly, it was insufficient to power the entire facility.
Cambio recommended changes to state law, requiring hospitals, nursing homes and retirement homes to have sufficient backup-generator power to operate elevators and air conditioning.
The only problem: According to Chris Coulter of Texas Power Agents, such backup generators require regular maintenance. They also require oil and fuel, such as gasoline, which may be hard to find during widespread power outages. After Beryl, the lines I found at functioning gasoline stations stretched for more than a half mile.
Voluntary Best Management Practices May Not Be Enough
I asked Coulter, who was not at yesterday’s roving recovery meeting, for recommendations about how to improve electric reliability.
He immediately focused on vegetation management and tied the growth of vegetation over time with the increasing frequency of power outages.
The FERC report cited above says that utility vegetation management programs represent one of the largest recurring maintenance expenses for electric utility companies in North America.
Coulter jokingly characterized companies like CenterPoint as “tree trimming companies that happen to distribute power.”
“The odds are that every single electric customer in the US and Canada has, at one time or another, experienced a sustained electric outage as a direct result of a tree and power line conflict.”
This FERC report is well written and easy to understand. It makes dozens of common-sense recommendations to improve electric reliability. I recommend it.
Coulter also referred me to NERC, the North American Electric Reliability Corporation. NERC describes itself as “… an international regulatory authority whose mission is to assure the effective and efficient reduction of risks to the reliability and security of the grid.”
Coulter said that NERC rules recognize different sizes of lines in regard to vegetation management requirements. Heavy fines apply if vegetation is ignored around lines that carry more than 100 kV.
However, lines that carry less power often get neglected – something that hampers recovery.
Coulter said that many of his Kingwood customers told him about seeing several such lines for the first time after Beryl. They didn’t even know the lines were there because they were so badly overgrown!
Said Coulter, “The NERC rules are very specific about frequency and minimum vegetation clearance distances for larger transmission (above 100 kV). Fines are steep so the utilities pay close attention and abide by the rules. However, Kingwood has a large spiderweb of distribution lines that are below that bright-line designation.”
Perhaps the fines need to apply to smaller power lines.
Next Step: Broaden the Discussion
Dee Price is reaching out to trail and community associations to set up a meeting about vegetation management. It will also involve our elected representatives, CenterPoint and Houston Public Works.
At a minimum, I came away from yesterday’s discussions with a feeling that we need to:
Raise awareness of vegetation management issues within the community
Handle those on private property that could affect electric lines by ourselves
Report problems on or near CenterPoint easements that they may not be aware of.

Daniel and Kathleen Moore live with their 8-month old baby near the East Fork San Jacinto in Montgomery County. The young couple desperately wants a buyout after their house on Idle Glen in New Caney flooded three times in seven years. But no buyout is in sight.
When they bought the home, they were told it was in the 500-year floodplain. In fact, Montgomery County flood maps still show their home is in the 500-year (.2% annual chance) floodplain.
However, that determination is based on floodplain data from the 1980’s – before the Moores were even born. And since then, the area upstream from them has boomed with new development.
New Upstream Development Invalidates Old Data
For instance, Colony Ridge, just 2.5 miles to the northeast on the other side of the river, has grown 50% larger than Manhattan since 2010 – with virtually no flood mitigation measures on the East Fork side of the area.
In one seven year stretch (2017 to 2024), the Moores flooded three times. During Harvey, they flooded to nine feet. In Imelda, they got one foot. And in the no-name storm of May 2024, five feet of floodwater destroyed everything in the bottom floor of their home.
Said Daniel, “I figured Harvey was extreme. I didn’t worry too much about that. But the next two storms were different. We just can’t afford to rebuild every two or three years.” Daniel works as a mechanic. “The pay isn’t that great,” he says. “We need to move.”
Rebuilding Without Flood Insurance
After the first two floods, they rebuilt the home with money from their own pockets – without benefit of insurance. But with a new baby, they can no longer afford that.
The Moores’ story underscores how inexperience can hamstring young couples on technical issues, such as floodplain delineation and flood insurance.
The moral of this story: before you invest in a new home, consult with a professional hydrologist about the risk. Talk to neighbors about past flooding. Look for tell-tale signs like mold on neighbors’ homes, rotting wood, and elevated structures.
And buy flood insurance. It’s available through FEMA and the National Flood Insurance Program. Not all agents feel the commission justifies the trouble of handling it, especially if the home has a history of flooding, so you may get mixed signals from them. Shop around.
Moore Photos During and After May 2024 Flood
Daniel tried to return home after spending the first night with his family in a motel. He couldn’t get onto the feeder road from SH99. This picture shows FM1485 totally flooded.

Cleanup after the Flood
I took the following shots on 5/18/24. As Daniel worked to gut his uninhabitable home once again, his wife tended the baby at her mother’s home.
Living room of Daniel and Kathleen Moore destroyed by flooding in May 2024Daniel points to height of flood waters. For reference, he is 6’5″ tall.Possessions carted to curb and picked over by scavengers.
Scavengers feel, “What difference does it make? They’re throwing this out anyway.” But it makes flood victims feel victimized all over again. Daniel says he’s found people picking through his belongings every day since the flood.
Floodwater reached the top of Kathleen’s Tahoe. It floated during the flood and turned 90 degrees. No one knows where the phone pole came from.Daniel, tired, bewildered, and still a bit dazed.
But the Moores’ trials and tribulations are not over.
Buyout Chances
The Moores have had a hard time connecting with anyone in Montgomery County who will offer them a buyout.
Ironically, the fact that they are in a 500-year floodplain that hasn’t been updated in 40 years could hurt their buyout chances. FEMA scoring generally favors those with higher risk.
FEMA also favors homeowners with flood insurance. That’s because buying out the homeowners would likely save FEMA money on insurance reimbursements after multiple floods.
But that’s not all.
River Rising Again
Before leaving the Moores’ home, I put my drone up and saw this.
East Fork rising again. Out of banks and flooding FM1485 (right) near 1 PM on May 18, 2024. Looking E.Note river on middle right already had risen over one road in the neighborhood.Daniel says FM1485 is totally under water now.
As of 6 PM, the National Weather service shows the river is still rising. They predict it will crest tonight just under major flood stage near 69 feet.
NWS prediction as of 5:52 PM on 5/28/24 for gage within blocks of Moore home.
That should bring the water close to the Moores’ front door again.
As I drove around his neighborhood, I marveled at the number of abandoned and flooded homes. One can only wonder whether this neighborhood will survive.
Please pray for the safety of all who live there.

Today, it wasn’t Republicans vs. Democrats. It was humans helping humans. And how refreshing it was!
86-Year Old, Mobility-Challenged Woman Gets New Home, New Life
Texas General Land Office (GLO) Commissioner Dawn Buckingham and her staff gathered to turn over the keys to the newly rebuilt home of Earnestine Henry. Ms. Henry is an 86-year old African-American great grandmother who relies on a wheelchair and walker to get around. Hurricane Harvey displaced her from the 79-year old home she owned for 50 years.
Neighbors, friends and family – the entire street – all joined in the festivities. It was the 1000th such home that the GLO built in Houston and Harris County in the last two years.
When Commissioner Buckingham gave Ms. Henry a bouquet of flowers as a housewarming gift, Ms. Henry began to cry tears of joy.
Henry left, Buckingham right.
Then, the deeply religious Henry threw up her arm and went silent for a second.
Finally, she shouted “Thank you, Lord.”
She was so overcome with emotion that Commissioner Buckingham reached out to steady her in case she started to fall.
The room went silent as she sobbed and dried her tears. Everyone else dried theirs, too, including seasoned journalists. Yes, even I sniffled.
Then Ms. Henry flashed a beatific smile. The gracious and grateful octogenarian then took her guests on a tour of her new home as she thanked all the GLO staff in attendance.
She never thought she would recover from Harveyand couldn’t believe her beautiful new surroundings.
Before/After Photos
Here’s what the home looked like before the rebuild.
And here’s what it looked like today, including the handicapped ramp. All homes built through the GLO’s Homeowner Assistance plan meet the needs of the residents with mobility challenges. Not only is the homeowner’s investment protected, their safety is as well.
Ms. Henry had originally applied to the City of Houston for help after Harvey, but reportedly never heard back. Her daughter and granddaughter helped her reapply to the GLO when the GLO took over the program in 2021.
Better, Safer
JW Turner Construction built the new home, which is fully code compliant and energy efficient. The rebuild happened as part of the GLO’s Homeowner Assistance Program (HAP).
In accordance with federal law and City of Houston codes, new homes located in a flood plain are elevated to 2 feet above base flood elevation.
Property Values Increase, but Not Taxes
On average, homes rebuilt through the Homeowner Assistance Program increase the value of the property by more than $85,765. To address concerns about increased property taxes, in 2019 the Texas Legislature passed Senate Bill 812 to protect homeowners from drastic increases after the GLO reconstructs homes.
The GLO’s Homeowner Assistance Program reaches the hardest hit, low- and moderate-income, vulnerable families and individuals.
1000th Rebuild Part of a Continuing Effort
Of all approved applicants, nearly 90 percent identify as Black or Hispanic. 89 percent are considered low-to-moderate income. And 63 percent make less than 30 percent of the area median income.
The GLO currently has another 1000 homes under construction in the Houston area.
“No other state or territory has performed like Texas in the recovery from Harvey,” said Buckingham. “A large part of that credit goes to the GLO. In two years, GLO has rebuilt 18 times as many homes as Houston and Harris County combined.”
“Texas stands to lose billions of available federal disaster recovery dollars if we do not use them before they expire in August 2026,” she added.
“Programs administered by the GLO in assisting the poorest Texans have significantly outperformed the federal requirement,” said Buckingham. 80% of GLO disaster recovery funds help those most in need, even though the US Department of Housing and Urban Development only requires 70%.
Buckingham, upper right, applauds her team and contractors who commemorated the occasionwith Ms. Henry.
Thank you, Lord, for people like Ms. Henry and all the others above. They remind us that we’re all in this together.

2025 Days since Hurricane Harvey
https://i0.wp.com/reduceflooding.com/wp-content/uploads/2023/03/20230316-RJR_1258.jpg?fit=1200%2C800&ssl=18001200adminadmin2023-03-16 20:45:152023-03-17 08:48:58“Thank You, Lord!” and “Thank You, GLO!”
Says Lindner, “Early on the 24th, surface low pressure developed over south-central Texas. It helped draw a warm front northward. It eventually formed a line from near Sealy to Downtown Houston to Chambers County. This warm front when combined with strong lift, impressive low level wind shear, and winds changing direction, resulted in the formation of supercell thunderstorms along a line from near Victoria to Sealy to Conroe.
They trained across northwest Harris County. Rainfall amounts southeast of US59 ranged from 1-2 inches, but 2-6 inches northwest of 59.
One of the storms along the front produced a tornado over southern Fort Bend County. Another formed over northern Brazoria county near Pearland. Rotation increased as it tracked through SE Houston, Pasadena, Deer Park and Baytown.
Duration and Rates
The heaviest rainfall occurred over portions of west, northwest, and northern Harris County in a 3 to 6 hr period. Several locations in northwest Harris County recorded 1.0-3.0 inches of rainfall in an hour during the late morning hours. Additionally, as the line of storms moved eastward, numerous locations recorded 1.0-2.0 inches of rainfall in 15-45 minutes. That resulted in rapid street flooding over many portions of Harris County during the early to mid afternoon hours.
Total 6-hr rainfall amounts ranged from 3.0-6.0 inches from north of Katy along west/north of FM 1960 into the Humble and Kingwood areas. The highest amount was at John Paul Landing Park in northwest Harris County where 5.48 inches was recorded in 3 hours. Unfortunately, most of this rain fell on grounds that were still wet from heavy rainfalls on January 8 and 9. This maximized runoff into area creeks.
Lindner points out that, “Heavy rainfall and flooding can occur every month of the year in Harris County and there have been other recent heavy rainfall events in January. Compare rainfall duration and intensity in the table below.”
“Cool season” events tend to be short in duration with the majority of the rain occurring in 6 hours or less,” says Lindner.
Interestingly, all of the January flooding events listed above had identical contributing factors: a surface warm front, high moisture levels, and training movement over the same area.
Rainfall amounts for the 1- and 3-hour time periods ranged from 2- to 10-year rains on the Atlas 14 scale. For the most part, channels could accommodate the rainfall. No widespread house flooding occurred although streams came out of their banks at numerous locations and came dangerously close to homes. See below.
Homes surround by floodwaters near West Fork San Jacinto on 1/30/23.
Tornado Impacts
The tornados were a different story, though. As they swept across the southern part of the county at 40 to 60 mph, they produced significant damage.
Lindner said, “Video obtained from the City of Deer Park indicated a tornado heavily shrouded in heavy rainfall with very little if any visibility of a condensation funnel or lofted debris. Unlike tornadoes in the Great Plains, many of the tornados along the US Gulf coast are hidden within heavy rainfall and very difficult to observe.”
Damage assessments as of February 7, from the cities impacted indicate approximately 1,635 single family homes were damaged, 855 multi family units, and 15 mobile homes. The tornados ranged from EF0 to EF2 in intensity. EF2 winds range from 111-135 mph.
Jeff Lindner, Harris County Meteorologist
For a complete listing of rainfall intensities and damage assessments at different locations through the county, see Lindner’s report here. It contains an interesting history of tornados in Harris County.
The pictures below were taken by a retired Kingwood resident, John Knoerzer, who owned a business in one of the hardest hit areas. They illustrate damage in Pasadena at one of his former employee’s home and shop.
Roof and walls torn away by winds. Note sheet metal twisted around tree in upper right. That came from a neighbors home several hundred feet away.Sheet metal from same building shredded the power lines in this 23-second video.
Never Bet Against Mother Nature
Lindner’s report and these images provide powerful reminders of why we should never take flood or wind risk for granted. And why we need to see flood-mitigation projects through to completion.
These were only 5-year storms. But remember. Those exceedance probabilities are like odds on a Las Vegas roulette wheel. I once saw the same number come up six consecutive times!
Don’t bet against Mother Nature. Insurance gives you much better odds.
