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.

In three years of writing about flooding, this is one of the most dramatic case studies I have seen about the value of wetlands. It starts with a developer clearing wetlands and ends with the developer at war with a neighboring town.
Wetlands as Protectors
Michael Shrader lived in a modest home in Plum Grove in Liberty County. It was an idyllic, rural lifestyle in many ways. He did tech work remotely while raising animals on his small plot of land near the East Fork of the San Jacinto and Maple Branch. Shrader never flooded for the first 29 years he lived in Plum Grove despite living on a creek. Not in 1994. Not in Allison. Not in Rita. And not in Ike.
Forests filled with wetlands surrounded him. Water ponded during heavy rains. Much of it soaked in and was absorbed by tree roots. The creeks ran clear.
Before Colony Ridge
In this 2008 Google Earth image, you can see the vibrant greens. And if you look closely enough on a desktop display, you can even see the ponds and wetlands east of FM1010.
Note area east (right) of FM1010.
For those reading on smaller displays, here’s the same image, but with data from the US Fish and Wildlife Service National Wetlands Inventory superimposed.
The bright, solid greens represent wetlands in the national inventory. Superimposition courtesy of Michael Shrader.
Then Came the Bulldozers
In 2016, the developer of Colony Ridge started clearing land and replacing wetlands with ditches that fed into Maple Branch. It runs right behind Shrader’s home. As the developer filled in more and more of the wetlands, water started getting higher in the creek after every rain, according to Shrader. Harvey, May 7th, Imelda: those were the high-water marks. And the low points in Shrader’s life. He flooded all three times.
By last year, the developer had replaced virtually all the wetlands by this.
By 2/23/19, most of the wetlands had been turned into streets with ditches in the world’s largest trailer park. Shrader lives on a stream that cuts across the NW portion of the grid.
Since the satellite image above was taken, even more forests and wetlands farther east and north have been replaced by what is now the world’s largest trailer park.
Eastern area in June, 2020.

Lives Disrupted
With the wetlands gone, Shrader’s house flooded in 2017 during Harvey (admittedly an extreme event), and twice in 2019. Not only did his house flood, so did most of Plum Grove, including the City Hall. Now, Shrader says, many homes are vacant.
The fence below, immediately downstream from the Camino Real Subdivision in Colony Ridge, was pushed over three times by the increased flow of floodwaters coming down Maple Branch. The owners of the red-roofed house bought this property just before the first of three floods.
Flooded Plum Grove home near Maple Branch and Colony Ridge. Owners stopped repairing the fence after the second flood.
At least one investigative journalist is exploring alleged predatory lending practices.
Allegations of corruption in Liberty County politics abound.
Commissioner’s Court and City Council meetings have degenerated into heated shouting matches.
Soon, Hollywood screenwriters will develop screenplays based on the Plum Grove experience and pitch them as “the next Erin Brokovich.”
Eroded drainage ditch in Colony Ridge that blew out FM1010 at far end. Three years after Harvey, the road still had not been repaired, much to the dismay of residents.
FM1010, one of the main roads into and out of the development, destroyed by out-of-control stormwater.The loss of this road has led to massive traffic jams on alternate access routes, such as FM2090.
Sadly, a little more respect for Mother Nature could have easily prevented all that trouble for the developer. One wonders whether the engineers and environmental consultants whom he hired to obtain permits served him well.

A seven-month-long TCEQ investigation of Colony Ridge construction practices resulted in a 184-page report that confirmed allegations of erosion and silt flowing uncontrolled into ditches and streams. The investigation resulted in a “notice of enforcement.”
TCEQ Alleges Permit Violations Affecting Human Health
TCEQ found the Colony Ridge developer in violation of its Construction General Permit for failure to install even minimum controls such as silt fences and vegetative buffer strips.
As a result, the report says the developer failed to prevent discharges that “contribute to a violation of water quality standards” and that have “a reasonable likelihood of adversely affecting human health or the environment.”
Investigators found unstabilized and unprotected drainage channels connecting 3,678.69 acres of disturbed land to unprotected streams and creeks. Sediment now almost completely fills some of those streams. They lead to Luce Bayou and and the East Fork San Jacinto River, which empty into Lake Houston, the source of drinking water for 2 million people.
Lack of Construction Best Management Practices
Colony Ridge’s Construction General Permit does not authorize discharges into Texas surface waters. Yet investigators found:
Drainage ditches with unstabilized soil on their sides
A drainage ditch with completely destabilized sides
Sediment deposition in multiple creeks
One creek channel almost completely filled by sediment
Culverts blocked with sediment
A washed out road
Water samples with elevated levels of dissolved and suspended solids as high as 1370 milligrams/liter (suspended) and 6360 (solid)…
...All tied to inadequate or non-existent best management practices
See photos below.
Self-Reports in Stark Contrast to TCEQ Report
In contrast, the construction superintendent’s own inspection checklists (pages 51-78) rated virtually all erosion-prevention measures that the company did employ as “acceptable.” However, he also indicated that the company did not use most common protective measures, such as vegetation, sod, silt fences and detention basins; claiming they were “not applicable.” His report on 2/19/20 contained a note indicating the construction site “Looks good.” His last weekly report before the complaint that triggered the investigation found no “action items.”
Below is a sampling of ten photos from the report. The TCEQ investigator took them all on 6/16/2020. He also provided the captions. Page numbers refer to the full TCEQ report.

Personal Observations Corroborate Report
Based on personal observations, I don’t think the investigator exaggerated. On the contrary, he may not have captured the full scope the hazards. Some can only be seen from the air. As luck would have it, I flew a helicopter over Colony Ridge on the same day the investigator captured his photos. Here are two from the air and one from the ground.
Washed out ditches abounded.
The developer was clearing more land before previously developed areas could be stabilized.
Silt fence being propped up to allow raw sewage to flow underneath it into Luce Bayou, which empties into Lake Houston.
Other Strangeness
Colony Ridge hired Merit Professional Services in Flower Mound, a Dallas/Fort Worth suburb. Merit obtains stormwater pollution prevention permits and also provides stormwater inspection services. However, according to the complainant in this case, Merit claimed they only provided the permit, but not inspection services. Lack of local oversight may have been a large part of the problem.
Ironically, Double Oak Construction is a defendant in the Elm Grove lawsuits against Perry Homes and its contractors on the Woodridge Village project in Montgomery County. That case involves many of the same issues involved in both the TCEQ report and the City of Plum Grove’s lawsuit against the developer of Colony Ridge. The report does not mention exactly when Double Oak started working for Colony Ridge.

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.

More recent independent laboratory testing has verified fecal contamination in at least two drainage ditches in Colony Ridge. Moreover, residents claim they have found fecal contamination in other Colony Ridge ditches and streams, too. It’s not clear whether those additional spills have been tested.
During heavy rains, fecal contamination can quickly wash downstream and eventually wind up in Lake Houston.
A major concern of residents is the frequency of sewage leaks.
Results of TCEQ Investigation
Maple Branch Creek carried black water into the East Fork.
TCEQ cited Quadvest L.P., the sewage and water provider for Colony Ridge, for “unauthorized discharge of wastewater which resulted in a documented serious impact to the environment.”
A month after TCEQ documented this discharge, 33 inches of rain fell on nearby Plum Grove during TS Imelda.
Here are results of the first test and pictures of the sewage.
The first site on a ditch next to County Road 5023 showed 3090 and 3130 units of fecal coliform, with none detected in the control sample. Maria Acevedo photographed this problem on June 4, 2020.

Second Eastex Report Shows VERY STRONG Fecal Contamination
Samples collected and analyzed by Eastex Environmental Labs, eliminating chain of custody issues.
The lab told Acevedo that they found “very strong fecal contamination.”
Maria acevedo
Residents who wish to remain anonymous for fear of retaliation, contacted me about this site a week before Eastex sampled it.
Location of Second Sample Photographed on 6/12/2020
I photographed that ditch on Friday, 6/12/2020. It’s on the southeast corner of Colony Ridge. While there, I photographed cloudy water bubbling up out of the ground and running down a ditch toward Tarkington Bayou (see photos below).
Foul water and trail of greenish-brown sludge (left) bubbling up through ground……then flowed into ditch toward Tarkington Bayou at bottom of hill.Close up of water/sludge in ditch.Silt fence in ditch was propped up, ensuring foul water could ooze under it.Farther down the ditch, contaminated water was pooling, and turning green and black.In places, it had dried due to extreme heat. Temp was in 90’s.
Photos Taken Two Days Later Show Attempted Coverup
I came back two days later on 6/14 to explore the same area some more. The foul water still bubbled up, but someone with a bulldozer attempted to cover up the evidence in the ditch.
Sludge and contaminated water bubbled up from same hole on 6/14/2020.However, the evidence in the ditch near the road had been freshly covered up by a bulldozer.
The Leaks Go On
If the incidents above were isolated, one might dismiss them. But they seem to be part of a larger, recurring pattern that neither Colony Ridge, Quadvest, nor Liberty County have stopped.
A resident says this sanitary sewer was leaking for more than two months into a ditch in a residential neighborhood and stunk like sewage.Photo by Maria Acevedo on CR5006 on March 18, 2020.
The largely Hispanic residents complain among themselves. But few reportedly file reports for fear of raising their profiles with authorities and perhaps answering difficult questions in court. Meanwhile, the sewage leaks go on. Both Colony Ridge residents and those downstream pay the price.

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.

The world’s largest trailer park in Liberty County, Colony Ridge, currently covers more than 10,000 acres and has only a handful of fire hydrants. This may sound unrelated to flooding, but it shows the general quality – or lack thereof – of development practices. That same lack of quality in other practices contributes to flooding, which I will discuss later in this post.
Three Hydrants Spotted in 8,400 Acre Portion of Development
In four hours of driving through Colony Ridge, I saw only three hydrants. Two were at a school under construction and behind fences. The Plum Grove Volunteer Fire Department directed me to the third. It services an 8,400 acre portion of the development.
When I got there, a pumper truck from the Cleveland Fire Department (10 miles to the north) was filling its water tank. I followed it to a fire almost two miles away.
Member of Cleveland, TX, fire department re-filling his pumper to fight a fire almost two miles away.
At the fire, it joined four other pieces of equipment fighting the same fire.
Firefighters from Porter, Cleveland and Plum Grove respondedto a brush fire that threatened several homes.
Brush Fires Common Threat
The Cleveland firefighter told me that brush fires were the most common call they received from Colony Ridge. In fact, while driving around, I saw a dozen brush fires that people deliberately started to help clear their property. Most fires were contained, but on a windy day, the risk soars with the embers. The risk above got out of control.
Another brush fire near the one that got out of control. Residents commonly burn brush cleared from their property.
It felt as though homes on every block had brush piles near them. Burning reduces disposal costs but also creates a high fire risk and air pollution. Therefore, most areas forbid such burning. But it is a common practice in Liberty County, especially in Colony Ridge.
Note brush pile on leftbehind house.
What Happens When There’s No Water Near the Fire
Pumper trucks are one of the most common pieces of fire fighting equipment, especially in rural areas. They bring water to a fire when hydrants are not available. But Colony Ridge is far from rural at this point. It covers an area almost as large as Kingwood. Kingwood has four fire stations. It also has hydrants every few hundred feet.
This area is big enough and densely populated enough that it should have its own fire station. Plus fire hydrants on every block. Instead, firefighters must shuttle pumpers.
Ten Minutes of Water Per Load
The firefighter from Cleveland told me that most of their pumper trucks hold 1,000 gallons of water. Some hold 2,000. But fighting a fire requires 100 gallons a minute, he said. That means they usually run out of water within 10 minutes. And that means they must shuttle multiple pumper trucks to a fire.
Because firefighters can’t directly hook into a hydrant for a continuous supply of water, some must fill tanks while others fight the fire. He also said, it usually takes at least 5,000 gallons of water to put out a house fire of the size they usually encounter in Colony Ridge.
“In a water-shuttling operation, you’ll have someone dumping, someone refilling and someone on the way to refill. It’s a continuous operation and very labor intensive,” said a fire expert in this Houston Chronicle article.
Fighting Other Obstacles on Way to Fires
Just getting to a fire in Colony Ridge can take valuable time. With washed out roads, limited access, heavy traffic and firefighters coming from up to 10 miles away, fires can consume homes before units even arrive.
The Challenge of Multiple Fires
I wondered, “What would happen if there were multiple fires?” When I got home, I learned that there WERE multiple fires on Sunday afternoon. While I was photographing one, a second grass fire occurred in another part of the development. Two firefighters monitored it to make sure it didn’t spread. Luckily, it was in an area where homes had not yet been built.
Such are the joys of living in a development where fire hydrants are virtually non-existent.

Colony Ridge No Longer Rural
In rural areas, pumper trucks may be the only cost-effective alternative. Stretching water lines from ranch to ranch just is not financially feasible. But in urban areas, it’s a different story. Firefighters prefer hooking up to a hydrant so they can pump water continuously. Colony Ridge turned from rural to urban overnight.
The infrastructure no longer supports the new reality of the development.
In a development designed for tens of thousands of people, you would think county authorities would require hydrants.
In the not too distant future, thousands of additional residents will crowd into this area. With the one fire hydrant by the Dollar-General store miles away, residents will face big risks.
Cost of Adding Fire Hydrants
Ironically, the water supplier for this area, Quadvest, already runs water to all the properties.
Letter from Quadvest to resident. Rancho San Vicente is one of the subdivisions within Colony Ridge.
It would be easy to add hydrants, but they cost money. How much?
Recommended spacing for hydrants is every 500 feet in most urban areas. If hydrants were installed in Colony Ridge at that spacing, it would cost millions of dollars. Neither Quadvest nor the developer has yet seen fit to make that investment and Liberty County has not required it.
Same Story with Ditches
Here’s where the story comes back to flooding.
This same cut-rate approach permeates other facets of development such as drainage.
Harris County requires the banks of ditches to be planted in grass. But that requires seeding and mowing. In Colony Ridge, they avoid those costs, but pay a price in erosion.
Heavily eroded drainage ditch in Colony Ridge sends sediment downstream.Water from this ditch blew out FM1010 (Plum Grove Road) during Harvey and it has not yet been fixed.
Where roads cross the ditch in the photo above, small pipes constrict the outflow. However, the water under pressure in those pipes starts jetting. Turbulence on the downstream side further erodes the beds and banks of such ditches. Eventually, they will collapse and require extensive maintenance.
Water flows right to left. Notice erosion downstream of bridge from turbulence caused by water jetting through pipes.
This is a common hazard of inline detention.

As one flood expert said, “These homeowners may wake up someday to find the ditch in their backyards.” Such ditches will also be in rivers and streams.
Harris County discourages inline detention, such as you see in the photos above for another reason. First, offline detention is more efficient. It can capture more water, hold it until after a flood, then release it slowly.
Developers tend to like inline detention, though, because it lets them sell more lots. Meanwhile, others downstream pay the price.

Rapid runoff from Colony Ridge, perhaps the world’s largest trailer park, in Liberty County contributed to a washout of FM1010. Nearby residents in Plum Grove say it also contributed to the flooding of their homes. Moreover, erosion from the development has contributed to the buildup of sedimentation in the East Fork.
Nine years ago, this area was mostly forested wetlands. Today, it’s mostly mobil homes, many on barren lots, stretching mile after mile.
World’s Largest Trailer Park?
There is no definitive source ranking the size of trailer parks, but multiple references to Sun Valley in Nevada come up when you Google “world’s largest trailer park.” That development is one third the size of this one!
Nine years ago, Colony Ridge didn’t exist.
Satellite image from 2011.The land that would become Colony Ridge was covered with forests, wetlands and rice fields.Paper companies owned most of this land for decades and periodically harvested timber.Colony Ridge today. This is just the southern section. Two more sections are out of frame on the north.
By the end of 2019, Colony Ridge had grown to cover approximately 10,000 acres and it’s still expanding. It has transformed the landscape massively, and it’s not clear whether the development has provided sufficient detention to keep runoff at its predevelopment rate. Judging by the frequency of flood damage to surrounding homes and roads since Colony Ridge was developed, many local residents believe the answer is no.
Documentation about the design and effectiveness of the drainage systems is hard to come by. Authorities in Liberty County have not returned emails or phone calls. And the information is not posted online.
Entire Population Growth of Liberty County in Last Decade
Colony Ridge alone can account for all of the population growth in Liberty County in the last decade. The U.S. Census Bureau officially estimates that Liberty County’s population grew from 75,000 to 88,000 between 2010 and 2019. Unofficially, one local politician estimates the population of Colony Ridge to be about 20,000. Firm numbers are difficult to come by because many residents are undocumented and uncounted.
Contributing to Flooding?
Thousands of acres of trailer homes with open-ditchdrainageand no deed restrictions.Typical landscape in Colony Ridge is highly susceptible to erosion and rapid runoff.
The lack of deed restrictions means many have not planted grass. That accelerates runoff.
Also consider that the developer created many of the lots by filling in wetlands and clearing trees that used to retain water in storms. The absence of wetlands and trees also accelerates runoff.

Contributing to Road Blow Out
FM1010 lies in the path of a drainage ditch more than 2.5 miles long and 60 yards wide in places. It cuts like a butcher knife through the heart of Colony Ridge.
Satellite image shows massive erosion in straight-line drainage ditch that stretches for 2.5 miles toward Plum Grove Road, out of frame on the left.
The straight line nature of such ditches accelerates water and erosion even more. During Harvey, a combination of factors (population growth, lack of ground cover and deed restrictions, design of drainage, loss of forests and wetlands, impervious cover and extreme rainfall) all contributed to washing out FM1010. (See images below.)
Acceleration of runoff also shortens the time of accumulation during floods which heightens flood peaks.
The developer of Colony Ridge had an attractive vision for a niche market: to provide affordable plots of land without deed restrictions (at least in the early stages) to low-income families trying to escape the City. He marketed mainly to Hispanics who dreamed of owning their own land in America. The result may be a dream for some, but it’s turning into a nightmare for others.

Unintended Consequences or Foreseeable Tragedy
The giant ditch shown above leads directly to where FM1010 washed out. Along the way, there’s little to slow water down. The developer has installed twin culverts under a road that crosses the ditch. They may help. But judging by the results, they’re not working very well.
Cropped and enlarged from wide image above of Colony ditch.
From the bridge above, the elevation drops more than 27 feet in three quarters of a mile before stormwater goes into a strip of woods between FM1010 and the development. There, it gathered the momentum to blow out the road.

Detours and Delays
More than 2.5 years after Harvey, this road has yet to be repaired.
The loss of FM1010 makes northbound traffic detour through Colony Ridge or up US59 and then back east. As a result, residents say that it can now take an hour during rush hour to go the five miles from US59 to Plum Grove on FM 2090. But that’s not the only problem.
Rapid Sedimentation Downstream
Downstream from Colony Ridge, we’re now getting rapid sand build ups on the East Fork, much like we have on the West Fork from sand mines. According to boaters, the area shown below was 18 feet deep before Imelda. The deepest point in the channel when this picture was taken last December was 3 feet.

Here’s an update to last week’s watchlist. It includes seven Lake Houston Area developments – four from last week and three new.
Perry Homes’ Woodridge Village
On April 28, 2020, Harris County Commissioners approved the purchase of Woodridge Village from Perry Homes with two conditions: 1) that the City of Houston would defray half the cost by contributing $7mm worth of land that HCFCD needed for other flood control costs, 2) that the City would adopt new Atlas-14 rainfall statistics.
The next day, Houston Mayor Pro Tem Dave Martin discussed the deal on a Facebook live “virtual lunch” with the Lake Houston Area Chamber. At about 26:20 into the video, he said that the stipulations had already been agreed to. He said the City had already identified 11 pieces of property, 6 of which were presented to the County during its consideration of the deal in executive session the previous night. He also said the City would divert water from Taylor Gully to the Kingwood Diversion Ditch and build a barrier between Elm Grove and Woodridge, while the county built a regional detention facility.
Perry contractors went back to work the next day before Martin spoke. They continued working all week. They worked near Mace in Porter, on N2 (the large detention pond in the middle of the western border), and N3 (another detention pond on the eastern border).
A reliable source who needs to remain anonymous told me that the work was at the request of Perry’s lawyers. The source said that Perry and its contractors were simply complying with their contract.
This week marks the anniversary of the first storm (May 7th) that landed Perry in hot water. And forecasters predict an above-average hurricane season, which starts in four weeks. The lawyers may have had that on their minds, too. As they say in legal circles, “The third time is the pen.” Woodridge contributed to flooding Elm Grove twice last year, in May and September.

Romerica’s “Orchard Seeded Ranches”
This is the 331-acre project formerly known as the Heron’s Kingwood. It wound around the Barrington and River Grove Park. Romerica is now trying to develop the same land under a different name, “Orchard Seeded Ranches.”
However, on Thursday, 4/30/2020, the Houston Planning Commission deferred approval of the developer’s General Plan.
General Plan of Orchard Seeded Ranches in Kingwood Texas
The Commission then asked the developer to consult with the City Engineer; the Planning and Development Department; and Harris County Flood Control before bringing further requests back to the Commission.
That should send a strong signal to the developer that rough waters lie ahead. Any proposal will likely be debated publicly when/if the developer returns.
The development is still listed in CoH’s PlatTracker. So we will continue to watch this one.
Holley’s Kingwood Cove Golf Course Redevelopment
A review of the City of Houston’s PlatTracker Plus Map indicates that Holley has not yet applied for any permits on the golf course in Forest Cove. City of Houston confirmed that via a FOIA request (Freedom of Information Act).
Note how golf course on left is unshaded. That indicates no activity with the Planning Commission. Compare that to the purple area on the right for Romerica’s property. That indicates approval of a General Plan is still pending.
A review of the Harris County Appraisal District website indicates a limited liability company in Pittsburgh, PA, actually owns the golf course.

It’s not unusual for developers to use other people’s money. I shall continue to watch this. Holley says his engineer is reworking plans based on input from people surrounding the course.
Ryko Property Near Confluence of Spring Creek and West Fork
This property is in Montgomery County and the City of Houston’s Extra Territorial Jurisdiction. The Montgomery County Engineers office says the company has not yet filed any plans that have been approved. The City of Houston PlatTracker Plus Map also shows the owner has not yet filed any applications.

New Caney ISD High School #3
Dark green area in center between Sorters Rd. and 59 is future home of New Caney ISD High School #3.
The New Caney Independed School District plans to build a third high school south of the HCA Kingwood Medical Center and behind the car dealerships that front US59. I don’t know much more about this except that they plan to extend roads into the area that is now forest. High schools usually have large parking lots. And that means rapid drainage. It is unclear at this time whether MoCo will require detention ponds.
Northpark Woods

This high-density development along the West Fork San Jacinto River in Montgomery County is now about one-third to one-half built. Construction continues.
The Colonies in Plum Grove
North of SH99 in Plum Grove and east of the East Fork in Liberty County, lies one of the largest developments in the Houston region without detention ponds.
Formally known as Colony Ridge, some locals call it “The Colonies.” Colony Ridge bills itself as a “master-planned” community with six major subdivisions: Sante Fe, Camino Real, Grand San Jacinto, Rancho San Vincente, Montebello, and Bella Vista. Together they comprise 30,478 lots on approximately 10,000 acres at present. And they’re still growing!
The Colonies currently cover an area almost as large as Kingwood. Photo 4/21/2020.Drainage empties into the East Fork San Jacinto. While flying over the area, I did not see one detention pond. Mobil homes make up most of the housing stock.Note open-ditch drainage.
Colony Ridge advertises itself as “an escape from the city, land on which to grow and build a home, no restrictions and easy credit.” Aerial photos reveal people scratching out hardscrabble lives on barren lots.
This is a blue collar neighborhood. The developer says his target market is poor Latino laborers. They see this as a step up from apartment living and a chance to own a part of the American dream.
But while flying over it, I did not see one detention pond.
As SH99, the Grand Parkway, pushes east from 59, this area will boom. Without better drainage regulations, Liberty County and Plum Grove will heap their drainage problems on those downstream.

The good news is that Liberty County has joined with seven other counties to form a Southeast Texas Drainage District. The bad news is that Harris County is not one of the seven.
