Since June, I’ve posted about problems in the Colony Ridge development in Liberty County. Among them: the washout of FM1010 where it crosses over Rocky Branch. Authorities have closed the busy road which provides access to Colony Ridge for three years, forcing tens of thousands of residents to seek alternate access routes, such as FM1485 and FM2090.
However, it’s difficult to see all the damage. So today I took a drone and captured some previously unseen details.
Colony Ridge drainage ditch leading to Rocky Branch contributed to washing out FM1010 at far end of ditch.
Lack of Functional Detention Capacity Likely Contributed to Washout
The damage is likely the result of inadequate, poorly engineered, or poorly maintained detention. Another contributing factor: a steep drop in elevation as water leaves the massive ditch (see above) in Colony Ridge and descends through a wooded area toward FM1010. That drop accelerated more water than should have been traveling down Rocky Branch, an East Fork San Jacinto tributary. As a result, floodwaters swept trees and other debris downstream.
One Thing Leads to Another
The debris:
Clogged culverts under the road…
Then, when the roadbed became a dam…
…Water churned through the roadbed next to the culverts…
…And deposited more “beaver dams” downstream…
…that, in turn, contributed to the flooding of surrounding homes.
Years of Neglect Still Ignored
Amazingly, no one in Liberty County corrected these problems after Harvey. As a result, many homes flooded again in 2019, during heavy downpours on May 7th and September 19th. The problems still have not been fixed. See the pictures below. I took them this afternoon.
Just yesterday, I had lunch with a couple who were considering moving to Liberty County because they were seeking a quieter lifestyle. I told them about this story. They are reconsidering.
FM1010 Washout at Rocky Branch has not been repaired for more than three years. Note flood debris clogged in culvert. Also note straps around logs!
“Beaver dam” just downstream from culverts is building up and up, contributing to additional flooding.
Not All Business is Good Business
Colony Ridge has grown into the world’s largest trailer park in less than a decade. It brought more than its fair share of problems:
Legendary traffic backups – even on Sunday afternoons.
A hard lesson for some people to learn is that not all business is good business. Lax enforcement of regulations allowed Colony Ridge to grow out of control. Now county commissioners have a nightmare on their hands, cannot fix their problems, and cannot enforce their own regulations.

Fecal contamination of water can have many health consequences. It can also have consequences for your wallet in terms of hospital bills and water treatment costs. The expansion of Houston’s Northeast Water Purification Plant will cost $1.765 billion.
Persistent Sewage Leaks at Colony Ridge
Yesterday, I reported on 48,000 gallons of sewage documented by the TCEQ in ditches and streams near Colony Ridge in Liberty County just before Imelda struck last year. Stormwater from that area flushes into the San Jacinto East Fork and Lake Houston. Any sewage not cleaned up from that particular spill likely wound up in the main source of the City of Houston’s drinking water.
Had it been a one time affair, it could have been explained as an accident. But the problems recur. Neither the developer, sewage contractor, County, nor State have managed to eliminate the frequent leaks.
Sewage Coverup
In fact, yesterday’s post contained photographs of one incident where the leak remained. A bulldozer had simply covered up sewage that leaked into the ditch adjacent to a road. It was as if the people responsible were saying, “out of sight, out of mind.” The sewage leak remains, though, and without remediation, the pollution will eventually wash down toward Tarkington Bayou, which also enters the East Fork.
Putting Water Test Results in Context
Two recent tests of samples taken within Colony Ridge by Eastex Environmental Labs showed fecal contamination on the order of 3,000 to 5,000 “colonies” per 100 milliliters. Just what does that mean?
One-hundred milliliters equals a little more than six tablespoons.
The presence of fecal contamination is an indicator that a potential health risk exists for individuals exposed to this water. Diseases and illnesses that can be contracted in water with high fecal coliform counts include but are not limited to:
Typhoid fever
Hepatitis
Gastroenteritis
Dysentery,
Ear, nose, eye and cut infections.
Cost to Make Drinking Water Safe
On my last flight over Lake Houston, I flew over the expansion of the Northeast Water Purification Plant. Until you’ve seen this in person, it’s hard to believe how large it is.
The new plant will quintuple the amount of pure, fresh water available to customers in this area. The City is adding 320 million gallons per day (MGD) to the existing 80 MGD capacity for a total of 400 MGD.
In addition to conventional treatment processes, the new plant will include an advanced oxidation process called ozonation. Ozonation helps disinfect water to help ensure that harmful organisms such as Giardia and Cryptosporidium are eliminated. Ozonation also helps eliminate taste and odor causing compounds.
The intake facility shown below will finish next year, but the plant itself won’t finish until mid 2025.
All aerial images below were taken on 6/16/2020. While the plant expansion will make drinking water safe, it won’t make all the water in Lake Houston safe as long as people allow fecal contamination to leak into it.
The expanded plant lies more than a mile from the intake in the foreground.
The expansion will occupy approximately 150 acres of the City’s 252 acre site.
The new intake pump station will be located approximately 900 feet from the shore of Lake Houston to draw water from a deeper depth than the current intake.That, say the partners, will alleviate some water-quality challenges.Construction of the intake pump station should finish in about a year.The pipelines carrying water back to the treatment plant will measure 108″ in diameter.That’s nine feet tall. About the height of that cargo container used as a construction office!Photo cropped and enlarged from wider image above.
The City and its partners have produced an easy-to-understand, yet informative website that documents construction of this project.
This PowerPoint, posted as part of the latest update is packed with photos that may inspire your kids and grandkids to become engineers someday. It shows the meticulous planning and attention to detail that goes into such a project.
Objectives for Project
According to the web site, the project has two objectives:
To support the region’s growth
To reduce subsidence
But the partner’s sell themselves short. The fundamental reason is to provide safe, clean drinking water, despite the pollution from places like Colony Ridge.
For the record, lest you think I’m picking on Colony Ridge, there are many other sources of water pollution. They include livestock, leaky septic tanks, runoff from streets and more.
We can all help by reporting spills and leaks to City, County and State authorities when we see them.

Certainly, there are many honorable developers who try to build high-quality communities for people without adversely affecting downstream residents. I don’t wish to malign a whole profession. Nor do I want to fail to acknowledge the many wonderful communities they have built in this area.
But there are also some developers who put profit before people. They try to cut corners wherever they can and hope that nobody will notice. Especially regarding flood control. It’s expensive and easy because most people don’t understand it.
Grand Parkway Coming Soon To Wetlands Near You
The construction of State Highway 99, aka the Grand Parkway, has opened up vast new areas on the outskirts of Houston to developers. Many of those areas consist of wetlands and forests.
TxDoT is currently prepping land for Section H of the Grand Parkway almost all the way to FM 1960 on the east from US59.
From USGS. Wetlands near the path of Grand Parkway extension. Compare with maps above and below.
Visible Difference in Development Density Where SH99 Completed
The map below shows permit applications in the north Houston area. Compare the density of projects around sections of the Grand Parkway that have already been completed (left) with the areas on the east where the concrete has not yet reached.
This map shows permit applications in the northeast Houston area, both within the City and its ETJ (extra territorial jurisdiction. The Colony Ridge development featured below is outside the ETJ (green area) in the upper right of the map above.
Developers have even more projects underway outside the City’s ETJ (not shown on the map above).
How Development Can Affect Flooding
Kingwood residents have seen how one developer can contribute to flooding hundreds of homes. Last year, Perry Homes clearcut 268 acres north of Elm Grove before installing detention ponds. Hundreds of Elm Grove homes then flooded on May 7 and again on September 19, during Tropical Storm Imelda.
Below are recent photos of a massive 10,000 acre development in Liberty County near Plum Grove. It is about to become a 15,000 development now, thanks in part to Grand Parkway access. And yet it has only one small traditional detention pond.
Detention ponds slow down the rate of runoff to compensate for the loss of trees, wetlands and ground cover that have been replaced by streets and rooftops.
Their goal: to prevent downstream flooding.
Colony Ridge Accounts for All Growth in Liberty County In Last Decade
Colony Ridge can account for all the growth in Liberty County in the last decade. Below are some photos of Colony Ridge and its expansion near Plum Grove. The approach of SH99 will make it more accessible and therefore more attractive (at least from one point of view).
All aerial photos below were taken on 6/126/2020.
Looking north across the Grand Parkway extension toward Colony Ridge in Liberty County near Plum Grove.Just north of the Grand Parkway (upper left), you can see roads going in that will accommodate even more manufactured homes, aka trailer homes.The developer puts in roads, ditches, water and sewer. Fire hydrants? Forget it.
Developer’s Marketing Strategy
The developer tries to pass as many costs along to lot buyers as he can to maximize profit. He targets Hispanics. Residents tell me that sometimes two or three families may live in one of the homes you see here.
Nobody knows the real population of Colony Ridge because many residents are reportedly undocumented and uncounted.
Site work before parking a home is the responsibility of site buyers, many of whom openly burn brush to clear their lots. Like the developer, they’re trying to cut costs.
Land of Fire and the Forgotten
Resident burning brush on his property last Sunday afternoon.Residents aren’t the only ones burning.That smoke you see on the horizon is from dozens of brush fires set by the developer as he continues to clear land.Here’s one still smoldering.At this point, a major storm would bring the potential for uncontrolled erosion,just as it did in Woodridge Village in Montgomery County, above Elm Grove.As dry as it has been lately, the developer is burning brush piles next to woodlands. That increases fire risk. The barren surface also accelerates runoff and erosion, increasing flood risk.Note the haze and plums of smoke on the horizonand the vast expanse of exposed, packed dirt.The smoke is coming from burning piles of brush, such as these. If a fire spread into surrounding woods, local volunteer fire departments would be overwhelmed.No fire hydrants anywhere in sight.
If this were Houston, hydrants would be spaced at a minimum of every 500 feet. A firefighter told me that the spacing often depends of home values and population. Based on population alone, he believes this area should have hydrants.
One Small Detention Pond for 15,000 Acres
The developer has one detention pond (center) for the entire 15,000 acres. He relies on less efficient, in-ditch detention for additional capacity.Note the proximity to SH99 in the upper right.There are no detention ponds anywhere in the new areas being cleared. This is reminiscent of Woodridge Village which contributed to the flooding of hundreds of homes in Elm Grove.But Woodridge was only 268 acres. The developer relies on this and other drainage ditches to double as detention ponds in storms. But at the far end of this ditch……FM 1010 washed out during Harvey and destroyed one of the two major access roads into the development. The in-ditch detention failed. So has the county. The road has been out now for 1025 days, increasing the commute time for residents and the response time for firefighters.
Endless Loop of Construction and Destruction
State Highway 99 represents more than just a third loop around the City of Houston.
SH 99 will bring more developersand more people eager to escape downstream flooding issues.
Tapayer funded roads such as these create endless loops of construction and destruction. They are like a perpetual motion machine. Building one area floods another, causing people to move farther out and the cycle to repeat itself.
No one will admit it’s intentional, of course. The flooding is just a byproduct of greed. Cut a detention pond here. Substitute in-line detention there. Don’t bother planting grass to reduce erosion. Send your problems downstream. Let someone else worry about them.
One Chance
Do all developers think that way? Of course not. Many have principles and wonderful communities to show for them.
That notwithstanding, as one Splendora resident said, “They really only have one chance to get this right. If they screw this up, it will be almost impossible to fix and they will argue over who is going to pay for it for centuries.”
We are at that inflection point now.

Construction of State Highway 99, also known as the Grand Parkway, has turned south. It is now approximately 4.5 miles from FM1960, but more than 20 miles from reaching its goal of I-10. In the image below, taken on 6/16/2020, you can see it crossing the Luce Bayou Inter-Basin Transfer project and then heading through open farm land.
Looking southeast. Grand Parkway construction has now passed the Luce Bayou Inter-Basin Transfer Project. Approximately 4.5 miles remains before construction reaches FM1960 to the south.
The Grand Parkway will open up vast areas in Montgomery, Harris and Liberty counties for development. All of that will put pressure on Lake Houston, shown in the lower left of the satellite image below (which was taken seven months ago.
Now, more than ever, it’s important for these counties to work together to reduce the risk of flooding for downstream residents in Houston, which is the economic center of the region.
Without a vital, safe center, growth in the entire region could falter.
