Wayne Dolcefino, one of the country’s great investigative journalists, has been digging into Colony Ridge, as I have. So when he asked me last week if his videographer could hitch a ride on my helicopter, I said “sure.”
New Dolcefino Video Covers More Dimensions of Flooding Problem
While I shot hundreds of stills over Colony Ridge, his videographer shot 90 minutes of video. Dolcefino edited it together with other footage. His 8-minute video includes:
The most recent Liberty County Commissioner’s meeting
Attempted interviews with Trey Harris, the Colony Ridge developer
Some mind-boggling political donations made by Harris
An interview with a Harris County flood official
Articles from ReduceFlooding.com, including my recent Colony Ridge post, Rivers of Mud.
Wayne Dolcefino begs Liberty County Judge Jay Knight and commissioners to watch video of drainage violations at Colony Ridge before voting on new plats for the developer. They approved the plats without watching his video.
While I have focused primarily on the physical issues involved in flooding, Dolcefino has also focused on political issues. He literally digs deeper into the problem.
From Colony Ridge to the Liberty County Courthouse
The background for Dolcefino’s latest video is a Liberty County Commissioner’s Court meeting in which he attempted to show Commissioners video of drainage violations in Colony Ridge before they voted on additional plats for the developer.
Commissioners approved the plats after refusing to watch the video. Then, incredibly, one said he didn’t see any proof of violations.
And that – in one brief soundbite – explains why flooding is such a difficult problem to solve.
Colony Ridge violates Liberty County drainage standards because ditches have no backslope interceptor swales to reduce erosion.Most also lack grass.
I highly recommend Dolcefino’s video if you want to understand – in your gut – how politics can affect local flooding.
Out-Scrooging Scrooge
You may also find Trey Harris’ refusal to answer questions about deplorable living conditions in Colony Ridge, coupled with interest rates up to 13% on land purchases, quite interesting. It only took 177 years for someone to out-Scrooge Ebenezer Scrooge, the protagonist from Charles Dicken’s A Christmas Carol. But, in my opinion, the Colony Ridge developer now sets the standard.

Two new developments in Montgomery County, Audubon in Magnolia and Country Colony in Porter, will have no detention ponds. The two developments total almost 3,400 acres. During heavy rainfalls, they will dump their floodwater directly into local streams.
The commissioners expressed concern in their 2019 meeting about placing economic hardships on developers. Residents complained about the economic hardships caused by flooding. The developers won.
Theory and Problems with Flood Routing Studies
The idea behind flood routing is simple. If you can show you can get your floodwater to the river faster than a flood’s peak arrives, theoretically, you’re not adding to the peak. Therefore, theoretically, you’re not making flooding worse.
However, engineers and hydrologists point out several flaws with this “beat the peak” theory.
Flood-routing studies don’t consider the cumulative effects of other developments.
They are almost always based on outdated hydrologic models.
They assume “ideal” storm conditions.
“If you start with a brand new hydrologic model,” said one county engineer, “the modeling a developer does could theoretically be accurate. But his/her runoff changes the model. That runoff rarely gets incorporated into the model that the next developer uses.”
And, of course, if everybody rushes floodwater to a river during a flood, that’s the exact opposite of what you want. Holding water back in detention and retention ponds is the best way to reduce flooding.
The two new developments in MoCo exploit this routing-study loophole to avoid the cost of building detention ponds.
Audubon in Magnolia
The first, called Audubon Magnolia will contain 5,000 homes at buildout. It occupies 3,300 acres that drain into Mill Creek, Spring Creek and then the West Fork San Jacinto.
From Audubon’s drainage impact analysis. Note school being placed at edge of floodplain…before new floodplain maps are redrawn based on Atlas-14.
Section 3.1 of the Impact Analysis includes a description of the flood routing study and concludes, “Therefore, the increased flows are able to exit into Mill Creek before the flow from the bulk of the upper drainage basin arrives at the mouth of the stream.”
Correspondence with Montgomery County officials at the front of the document shows their concerns: use of pre-Atlas 14 data; impact on wetlands; building in floodplain; roughness co-efficients used to model speed of water over various terrains; and impact on water surface elevations.
Clearly, the floodplain administrator had major concerns about use of pre-Atlas 14 rainfall data. However, the developer was grandfathered based on the date of the original permit application.
Montgomery County’s new Atlas 14 standards increased the total for a 24-hour, hundred-year rain by 4 inches. The Flood Plain administrator encouraged the developer to model the higher rainfall totals and build to higher elevations. Why? To ensure the likelihood of compliance for those homes in the future.
These documents, dated 2019, are the latest available from Montgomery County. The county engineer’s office indicated that no detention ponds are being planned by the developer or demanded by the County.
Country Colony in Porter
The second development, Country Colony, lies just north of the Harris County/Montgomery County line at the end of West Lake Houston Parkway. Country Colony occupies approximately 80 acres immediately west of the Triple PG sand mine.
Note county line at southern edge of development. Also note how some of the lots are actually in the floodplain of White Oak Creek.Country Colony. Taken December 7, 2020, looking east toward Triple PG Sand Mine in background.
No detention ponds here either! A big heads up to the people downstream in Walden Woods, Woodstream Forest and beyond.

Two daredevil sand mining companies, Triple PG Sand Development, LLC and Texas Concrete, have stepped up their efforts to mine sand between pipelines that carry natural gas and highly volatile liquids.
AG Lawsuit Filed in 2019
In October of last year, the Texas Attorney General sued the Triple PG mine in Porter for up to $1 million on behalf of the Texas Commission on Environmental Quality (TCEQ). The original petition in the case cited repeated breaches in the mine’s dikes over a period of several years that let process water and sediment from the mine escape into the headwaters of Lake Houston. Lake Houston supplies drinking water for approximately two million people.
Days after the AG filed the suit, the mine’s owner, Dr. Prabhakar R. Guniganti, a cardiologist from Nacogdoches, tried to shuffle ownership of the mine through a series of trusts controlled by his family. In June of this year, the AG filed an amended petition, naming all the trusts and their officers (both individually and as directors) as additional defendants.
Both the TCEQ and AG’s office have declined to comment on ongoing legal matters relating to the Triple PG operation. However, while flying over the mine on Monday this week, I saw something very disturbing.
Mining Between Pipeline Corridors
Kinder Morgan has an easement for a natural gas pipeline through the mine. You can see the pipeline path on the left in the photo below. Their pipeline was exposed during Harvey by erosion and had to be buried deeper. Luckily, no explosions or fires resulted.
Looking NW. Mining between pipelines at the Triple PG mine in Porter.Natural gas line on left; HVL lines in utility corridor at top of frame.
Now, Triple PG and Texas Concrete are mining sand from between the pipelines. This will increase the potential for erosion in future storms. That could expose pipelines and potentially lead to pipeline ruptures, spills, and/or explosions.
Looking west. Removing additional ground cover makes the pipelines on either side more susceptible to erosion and exposure during floods.Looking south. Notice on right how mine has run heavy equipment across both pipeline corridors, a dangerous practice according to pipeline engineers.
To adapt a phrase about pilots from the aviation industry, “There are old miners and bold miners.” Those daredevils at Triple PG sure are Bold. With a capital B. As in Boom.

Two New MoCo Developments Will Total Almost 3,400 Acres, Have No Detention Ponds
Two new developments in Montgomery County, Audubon in Magnolia and Country Colony in Porter, will have no detention ponds. The two developments total almost 3,400 acres. During heavy rainfalls, they will dump their floodwater directly into local streams.
How Do They Get Away With That?
Sixteen months ago, on the second anniversary of Harvey, Montgomery County commissioners voted to leave open a loophole that lets developers avoid detention pond requirements. They said they would revisit the issue after the San Jacinto River Basin Study was completed. Even though partners shared study results with the public last August, MoCo commissioners have still not revisited the loophole called a “flood routing study,” also known as hydrograph timing.
The commissioners expressed concern in their 2019 meeting about placing economic hardships on developers. Residents complained about the economic hardships caused by flooding. The developers won.
Theory and Problems with Flood Routing Studies
The idea behind flood routing is simple. If you can show you can get your floodwater to the river faster than a flood’s peak arrives, theoretically, you’re not adding to the peak. Therefore, theoretically, you’re not making flooding worse.

Audubon in Magnolia
The first, called Audubon Magnolia will contain 5,000 homes at buildout. It occupies 3,300 acres that drain into Mill Creek, Spring Creek and then the West Fork San Jacinto.
Here is the entire 186-page Drainage Impact Analysis for section one. It also shows project plans and location.
Section 3.1 of the Impact Analysis includes a description of the flood routing study and concludes, “Therefore, the increased flows are able to exit into Mill Creek before the flow from the bulk of the upper drainage basin arrives at the mouth of the stream.”
Correspondence with Montgomery County officials at the front of the document shows their concerns: use of pre-Atlas 14 data; impact on wetlands; building in floodplain; roughness co-efficients used to model speed of water over various terrains; and impact on water surface elevations.

In that amended petition, we learned that a new operator started managing the mine in May of this year. However, Guniganti still owns it, according to the Montgomery County Appraisal District. The new operator is Texas Concrete, the same company that TCEQ fined in Plum Grove on the East Fork – for multiple breaches and other violations.
Both the TCEQ and AG’s office have declined to comment on ongoing legal matters relating to the Triple PG operation. However, while flying over the mine on Monday this week, I saw something very disturbing.
Mining Between Pipeline Corridors
Kinder Morgan has an easement for a natural gas pipeline through the mine. You can see the pipeline path on the left in the photo below. Their pipeline was exposed during Harvey by erosion and had to be buried deeper. Luckily, no explosions or fires resulted.
Additional pipelines carrying highly volatile liquids run through the utility corridor at the top of the frame. LMI exposed those same pipelines further northwest when it mined on both sides of them. Then erosion ate the sand out from under them.
Now, Triple PG and Texas Concrete are mining sand from between the pipelines. This will increase the potential for erosion in future storms. That could expose pipelines and potentially lead to pipeline ruptures, spills, and/or explosions.
To adapt a phrase about pilots from the aviation industry, “There are old miners and bold miners.” Those daredevils at Triple PG sure are Bold. With a capital B. As in Boom.
