Despite investigations by local, county and state authorities into construction practices at the Laurel Springs RV Resort near Lakewood Cove, contractors seem to have stepped up the pace of construction. They’ve also launched a major cleanup effort around the detention pond. Contractors triggered a cease-and-desist letter from the County Attorney, with the threat of a lawsuit, after it became apparent the developer was emptying its stormwater into Harris County Precinct 4’s Edgewater Park contrary to permits and approved plans. Contractors also apparently cut down a wide swath of trees in the northern part of the park.

The detention pond was to have drained into the Lakewood Cove storm sewer system with the aid of pumps. But there’s no inlet yet at the pond.

Overall, the developer appears to be cleaning up its act. But as you can see in the first shot, they seem to have made a significant and serious intrusion on Edgewater Park.

Several readers recently asked for a an update on the demolition of the remaining Forest Cove townhomes on Marina Drive. Three clusters remain near the Forest Cove Community Center. The vacant townhomes destroyed by Hurricane Harvey have become magnets for gangs, graffiti, dope dealing and illegal dumping. The people who wrote me avoid using the community center facilities because they now fear the area.
Difficulty and Delays with Demolition
Harvey flooded these once-proud buildings to the third floor. The flood swept some buildings off their foundations and rendered everything else structurally unsound. Harris County Flood Control District (HCFCD) has tried to buy out the properties ever since. However, they can’t tear down a building until all units within it have been purchased.
Most of the buildings have been torn down, burned down or swept away at this point. But HCFCD can’t find all owners. Several just moved away after Harvey and abandoned their property. That has stymied demolition efforts.
One Complex Scheduled for Demolition Soon
HCFCD’s property acquisition manager offered this update on the schedule for demolition.
Three buildings remain to demolish (1106, 1110 and 1020 Marina Drive).
1106 Marina Dr. is scheduled to be demolished within the next few weeks. That’s the building directly across Marina from the Community Center.
Two Still in Condemnation Proceedings
1110 and 1020 Marina Dr. will be demolished once the last 2 units are purchased (one in each building). These units are currently in condemnation proceedings.
Of the three remaining complexes, the one in the middle will soon come down. One owner couldn’t be found in this building. It is currently going through condemnation proceedings.One owner couldn’t be found in the building on the right. It is also going through condemnation proceedings.Not much remains. Someone could easily get killed or injured by stepping in the wrong place. Red area censored.Even the graffiti look terrified.What 240,000 cubic feet per second can do to your dream home with a close-up water view.
HCFCD also plans to clean up debris at the former location of 980 Aqua Vista in the near future. When HCFCD demolished that building earlier contractors left some materials behind.
Turning a Negative into a Positive
When HCFCD does finish demolishing these buildings, their long-range plan is to revert these properties back to nature and green space. That could turn what has become a blight on the community into an asset that supports the values of properties on higher ground.
Another good thing may come out of this. The destruction you see here may deter others from building these types of structures this close to a major river. Or even cause a change in building codes.
The theory here was that only garages would be built on the ground floor; living spaces would go safely above. That didn’t work out so well for the Forest Cove townhomes and those who invested their life savings.

How soon we forget. Hurricane Harvey was just 4.5 years ago. Since then I have documented dozens, if not hundreds of questionable practices that erode margins of flood safety.
It Didn’t Have to Be That Bad
Harvey was the largest rainfall event in the history of North America. However, with better regulations and construction practices, it didn’t have to be as destructive as it was.
Lax regulations;
Willful blindness;
Development and construction practices that pushed the safety envelope;
Relentless destruction of forests and wetlands near rivers and streams;
And homebuyers who didn’t realize their true flood risk…
…made Harvey’s destruction worse than it otherwise would have been.
No one factor by itself would explain Harvey’s destruction. But put them all together, and it’s like “death of a thousand cuts.”
The sheer volume of material – more than 1,000,000 words on this site – makes it difficult for people to see the big picture sometimes. To put 1,000,000 words into perspective, the average novel contains only about 100,000. So I’m condensing the website into a book that includes the themes below.
No One Wins Arguments with Mother Nature
During an interview with Milan Saunders and his daughter Lori, Milan said, “No one wins arguments with Mother Nature.” How profound! It doesn’t matter how many surveys, studies and engineer stamps you have on your home’s title. If you don’t:
Large islands built up during Harvey blocked both drainage ditches and rivers. Below, you can see a large sand island (top) built up at the confluence of the Kingwood Diversion Ditch where it reaches the San Jacinto West Fork at River Grove Park. This sand bar reached 10-12 feet in height above the waterline and helped back water up into Trailwood, the Barrington and Kingwood Lakes and Kings Forest. Before the Army Corps dredged this island, River Grove flooded five times in six months. It hasn’t flooded since.
The Kingwood Diversion Ditch and West Fork San Jacinto were almost totally blocked by sediment dams deposited during Harvey.
The second photo above was taken a few hundred yards downstream on the West Fork from the first. It shows “Sand Island” – so nicknamed by the Army Corps. It took the Corps months to dredge this island which they say had blocked the West Fork by 90%.
A certain amount of this sedimentation can be explained by natural erosion. But mankind also contributed to the sheer volume by other practices which I will discuss below.
Influence of sand mines of West Fork San Jacinto water quality.
End the War on Wetlands
Wetlands are nature’s detention ponds. During storms, they hold water back so it won’t flood people downstream. But we seem to want to eradicate wetlands. The images below show the Colony Ridge development in Liberty County. Wetlands (right) are being cleared (left) to make way for the world’s largest trailer park. The acceleration of runoff wiped out FM1010 during Harvey. The road still has not been repaired.
Colony Ridge in Liberty County.
Conservation Costs Much Less than Mitigation
Halls Bayou at I-69 near Fiesta. Image on left shows whole subdivisions that that to be bought out before detention ponds on right could be built.
Respecting Individuals’ Property Rights While Protecting Others’
In Texas, it sometimes feels that an individual’s right to do what he/she wants with property trumps others’ rights NOT to flood. You may think you’re protected by all those public servants reviewing and approving plans. But what happens when developers and contractors decide to ignore the approved plans? Here’s a prime example: the Laurel Springs RV Resort near Lakewood Cove.
About 10% of all the water coming down the West Fork at the peak of Harvey came from Crystal Creek in Montgomery County. But the wetlands near the headwaters of Crystal Creek are currently under development. And the developer is avoiding building detention ponds with a “beat-the-peak” survey. This loophole allowed by Montgomery County says that if you get your stormwater to the river faster than the peak of a flood arrives, then you’re not adding to the peak of a flood and you don’t have to build detention ponds. So developers conduct timing surveys to reduce costs and maximize salable land.
What happens when upstream areas develop without consideration for the impact on downstream property owners.
Of course, speeding up the flow of water in a flood is the opposite of what you want to do. To reduce flooding, you should hold back as much water as possible.
The graph on the right shows what happened on Brays Bayou without suitable detention upstream. Floodwaters peak higher, sooner. Harris County has spent more than $700 million in the last 20 years to remediate flooding problems along Brays.
How much will we need to spend when more areas like Mavera get built upstream on the West Fork?
How Quickly We Forget!
FEMA’s Base-Flood-Elevation Viewer shows that in that same area, developers have already built homes that could go under 1-5 feet of water in a 100-year flood. These homes are actually in a ten-year flood zone. And yet more homes are being built nearby. On even more marginal land!
In recent years, the price of land as a percent of a new home’s cost has risen from a historical average of 25% to approximately 40% today. This puts pressure on developers to seek out cheaper land in floodplains, reduce costs by avoiding detention pond requirements, pave over wetlands, and reduce lot sizes resulting in more impervious cover. All contribute to flooding.
Of course, smart homebuyers would not make such risky investments. But few lack the expertise to gauge flood risk. Educating such homebuyers will be one of the major objectives of the book I hope to write.

Laurel Springs RV Resort Construction Pushes Forward Despite Investigations

Investigations Still in Progress
Neither the County, City, nor Texas Commission on Environmental Quality would comment on the status of their investigations this week except to say that they are still ongoing. According to the Harris County District Clerk’s website, Harris County has not yet filed a lawsuit against the developer.
Overall, the developer appears to be cleaning up its act. But as you can see in the first shot, they seem to have made a significant and serious intrusion on Edgewater Park.

No One Wins Arguments with Mother Nature
During an interview with Milan Saunders and his daughter Lori, Milan said, “No one wins arguments with Mother Nature.” How profound! It doesn’t matter how many surveys, studies and engineer stamps you have on your home’s title. If you don’t:
…you will flood.
Understanding the Causes of Flooding
Excess sedimentation is one of them. Sediment pollution is the single most common source of pollution in U.S. waters. Approximately 30% is caused by natural erosion, and the remaining 70% is caused by human activity.
Large islands built up during Harvey blocked both drainage ditches and rivers. Below, you can see a large sand island (top) built up at the confluence of the Kingwood Diversion Ditch where it reaches the San Jacinto West Fork at River Grove Park. This sand bar reached 10-12 feet in height above the waterline and helped back water up into Trailwood, the Barrington and Kingwood Lakes and Kings Forest. Before the Army Corps dredged this island, River Grove flooded five times in six months. It hasn’t flooded since.
The second photo above was taken a few hundred yards downstream on the West Fork from the first. It shows “Sand Island” – so nicknamed by the Army Corps. It took the Corps months to dredge this island which they say had blocked the West Fork by 90%.
A certain amount of this sedimentation can be explained by natural erosion. But mankind also contributed to the sheer volume by other practices which I will discuss below.
Respect the Rivers
The red polygons in the satellite image below surround 20-square miles of sand mines on the West Fork of the San Jacinto in a 20 mile reach of river between I-45 and I-69. That exposes a mile-wide swath of sediment to erosion during floods and increases the potential for erosion by 33x compared the river’s normal width.
Even without floods, mines sometimes flush their waste into the rivers. The shot below on the top right shows the day the West Fork turned white. The TCEQ found the source of the pollution upstream: a sand mine that had flushed 56 million gallons of sludge into the West Fork (bottom right).
End the War on Wetlands
Wetlands are nature’s detention ponds. During storms, they hold water back so it won’t flood people downstream. But we seem to want to eradicate wetlands. The images below show the Colony Ridge development in Liberty County. Wetlands (right) are being cleared (left) to make way for the world’s largest trailer park. The acceleration of runoff wiped out FM1010 during Harvey. The road still has not been repaired.
Conservation Costs Much Less than Mitigation
All across Harris County, especially in older areas inside Beltway 8, apartment complexes, homes and businesses are built right next to bayous and channels. This makes it difficult to enlarge streams or build detention ponds when necessary. One study showed that preservation of floodplains is 5X more cost effective than mitigation after homes flood. Yet private developers keep crowding bayous and residents keep demanding public solutions.
Respecting Individuals’ Property Rights While Protecting Others’
In Texas, it sometimes feels that an individual’s right to do what he/she wants with property trumps others’ rights NOT to flood. You may think you’re protected by all those public servants reviewing and approving plans. But what happens when developers and contractors decide to ignore the approved plans? Here’s a prime example: the Laurel Springs RV Resort near Lakewood Cove.
The approved plans said that “Stormwater runoff shall not cross property lines.” So what did the contractors do? They pumped their stormwater over the development’s detention pond wall. When that took too long, they dug a trench through the wall. Then they laid pipes through the wall to permanently empty the sludge into the wetlands of Harris County’s new Edgewater Park.
This apparently violated the developer’s City of Houston permit, the Texas Water Code, TCEQ’s construction permit and the developer’s stormwater pollution prevention plan. Four investigations are currently swirling around this development. The contractor also cut down approximately 50 feet of trees in Edgewater Park along the entire boundary line and received a cease-and-desist letter from the Harris County Attorney. But the damage is done.
Balance Upstream and Downstream Interests
About 10% of all the water coming down the West Fork at the peak of Harvey came from Crystal Creek in Montgomery County. But the wetlands near the headwaters of Crystal Creek are currently under development. And the developer is avoiding building detention ponds with a “beat-the-peak” survey. This loophole allowed by Montgomery County says that if you get your stormwater to the river faster than the peak of a flood arrives, then you’re not adding to the peak of a flood and you don’t have to build detention ponds. So developers conduct timing surveys to reduce costs and maximize salable land.
Of course, speeding up the flow of water in a flood is the opposite of what you want to do. To reduce flooding, you should hold back as much water as possible.
The slide above shows part of a new development called Mavera at SH242 and FM1314 being built on wetlands near Crystal Creek.
The graph on the right shows what happened on Brays Bayou without suitable detention upstream. Floodwaters peak higher, sooner. Harris County has spent more than $700 million in the last 20 years to remediate flooding problems along Brays.
How much will we need to spend when more areas like Mavera get built upstream on the West Fork?
