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.

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.

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.”
