The Preserve at Woodridge is a novel single-family-home rental development going in off Woodridge Parkway between St. Martha Church and Kingwood Park High School. As with Woodridge Village, on the other side of the high school, the developer claimed the property was in no known flood zone. Even though it’s just outside the pre-Atlas 14 flood zones for Ben’s Branch, those zones are based on 40% less rainfall than the current standard for the Kingwood Area.
The Developer’s plansshow this note about floodplains on virtually every page.Atlas 14 was implemented in 2018.
A major drainage ditch also runs along one side of the development and contributes to flooding along Northpark Drive almost annually. I owned property on the other side of that ditch for 20 years and can attest to frequent flooding.
And even though runoff calculations are based on Atlas 14 estimates, those estimates are based on Conroe’s rainfall which gets about 10% less than Kingwood (48 vs. 53 inches).
The ditch in question was developed for what is now the high school. The earliest photo of it in Google Earth dates to 1995. Around 2008, the ditch was extended to handle drainage from Woodridge Forest. The developer’s plans do not specify the capacity of the ditch as far as I can see.
Hundreds of homeowners next to Woodridge Village in Elm Grove, North Kingwood Forest, Sherwood Trails and Porter subsequently flooded twice in May and September of 2019. They wound up suing Perry Homes, its subsidiaries and contractors, including LJA. Those cases recently settled.
The area immediately south of the Preserve at Woodridge includes approximately 40 businesses along Northpark Drive, the high school, St. Martha’s school, two churches, and dozens of homes in North Woodland Hills.
Let’s hope the engineers got this one right. Claiming “no floodplains” based on pre-Atlas 14 data and an old ditch whose level of service has diminished over time does not inspire confidence. How do they know for sure it won’t flood? But that’s not the only worry.
Rental Homes As Small as Studio Apartments
Guefen, the developer says it plans to build 131 homes on the 17 acres you see below. But the detention pond takes up five acres. That makes about 11 homes per acre of usable land with about 5 feet between many homes. You can see how close they are in the photo below.

Foundation forms in NW corner of subdivision along Woodridge Parkway.See corresponding plans below.Note how three of these homes could fit in the back yard of the home in the upper right corner of the photo.
Five of the eight homes above will have access only by sidewalks, not streets.
The same holds true for most of the homes in the subdivision.
In case of an emergency, that firetruck may be parking 250 feet away from some homes. That’s almost the length of a football field.
According to RentCafe.com, the average size of an apartment in Houston is 881 square feet. These detached rental homes will range in size from 668 square feet to 1,255 square feet. At the low end of that range, the square footage is about that of most studio apartments. For those of you who have never lived in one, a studio apartment hasone big common area that triples as a living room, bedroom, and kitchen. Only the bathroom has walls.

It’s always nice to start the new year by looking at the big picture. And big pictures don’t get much bigger than this. The image below comes from NOAA’s Global Data Explorer. It shows sea surface temperature anomalies in the Pacific and Atlantic. Reds show areas with warmer than normal temperatures. Blues are cooler.
Sea surface temperature anomalies from 12/20/21 to 12/26/21. Source: NOAA.
Degrees of Variation
The dark red areas are a whopping 4-5 degrees Celsius above normal. The dark blues are 3-4 degrees Celsius below normal. It takes 1.8 degrees Fahrenheit to equal 1 degree Celsius. So in terms of the temperature scale that most people in the US use, that’s up to 9 degrees warmer and 7.2 degrees cooler – a 16.2 degree spread.
This helps to explain the record warm December we just had. Houston is in that band of red that stretches across the northern hemisphere. Also notice how red the Gulf of Mexico is.
According to the EPA, an increase in sea surface temperatures can lead to an increase in the amount of atmospheric water vapor over the oceans. “This water vapor feeds weather systems that produce precipitation, increasing the risk of heavy rain and snow.” And we just had extreme snowfalls from the Sierras to the Rockies.
Role of Ocean Currents
Ocean currents help distribute this moisture around the world. According to NOAA, “almost all rain that falls on land starts off in the ocean.”
“Ocean currents act much like a conveyor belt, transporting warm water and precipitation from the equator toward the poles and cold water from the poles back to the tropics,” says NOAA. “Thus, ocean currents regulate global climate, helping to counteract the uneven distribution of solar radiation reaching Earth’s surface. Without currents in the ocean, regional temperatures would be more extreme—super hot at the equator and frigid toward the poles—and much less of Earth’s land would be habitable.”
Cyclical Variation
Sea surface temperatures vary in cyclical, but irregular patterns (roughly every 3-6 years). Right now, we are under the influence of a La Niña pattern, that recurs every few years and can last as long as two years. This page on NOAA’s site explains what causes the changes. They often start with ocean currents veering off course for a period of time or stronger than normal trade winds.
To compensate for the potential shortfall, Commissioners established a flood-resilience trust with money from other Harris County departments and changed equity guidelines in June.
To help you follow this story, I make quarterly FOIA requests for Harris County Flood Control District spending and post the analyses on a dedicated funding page.
Sand-Mining Best Management Practices
Activists led by the Lake Houston Area Flood Prevention Initiative and the Bayou Land Conservancy petitioned the Texas Commission on Environmental Quality (TCEQ) to establish best management practices for sand mines in the San Jacinto watershed. We didn’t get everything we wanted, but we got a vast improvement over what we had. And the new BMPs may help reduce erosion that contributes to future floods in this area.
West Fork Sand Mine illustrates need for vegetative controls to reduce erosion.
May 9, 2021, was 1349 days after Hurricane Harvey ravaged Texas and the Gulf Coast. That’s the number of days it took the US and its allies to win World War II. But during that time we’ve had few victories in the fight against future flooding in the Lake Houston Area with the exception of dredging, So far, we’ve mainly completed studies. And many of those are still in the works.
For instance, the City of Houston has been studying ways to increase the release capacity of the Lake Houston Dam. Right now, the release capacity is one-fifteenth that of the gates on Lake Conroe. That makes it difficult to shed water quickly before and during floods. FEMA gave the City money to study the problem, but is still finalizing recommendations. The City hopes to make an announcement in January.
The Texas Attorney General is still suing the Triple PG Sand Mine in Porter on behalf of the TCEQ. There has been little movement on the case in the last 18 months. The mine’s owner changed legal counsel in July 2020. A TCEQ representative says the AG has not given up. The two sides are still in discovery.
Approximately 1700 homeowners in the Lake Houston Area sued sand mines for contributing to flooding during Harvey. The cases were consolidated in the 281st Harris County District Court under Judge Sylvia Matthews. She recently set deadlines in the first half of next year for motions, depositions, joinder, expert witness testimony and more. The case is known as “Harvey Sand Litigation.”
Various lawsuits against the SJRA for flooding during Harvey are still working their way through the legal system.
Kingwood residents reached a settlement with Perry Homes, its subsidiaries and contractors this year over two floods that damaged hundreds of homes in Elm Grove and North Kingwood Forest during 2019. The incidents had to do with development of Woodridge Village, just across the Harris/Montgomery County line.

Bens Branch and Taylor Gully Cleanouts
In Kingwood, HCFCD finished excavating both Bens Branch and Taylor Gully to help restore their conveyance. Through gradual sediment built up, both had been gradually reduced to a 2-year level of service in places. That means they would come out of their banks after a 2-year rain.

LJA Parallels?
LJA, the engineer for Woodridge Village a block east also claimed “no floodplains.” That claim turned out to be tragically wrong. There were flood plains. They just hadn’t been mapped, like the ditch in question. And LJA used pre-Atlas 14 data in its calculations.
Hundreds of homeowners next to Woodridge Village in Elm Grove, North Kingwood Forest, Sherwood Trails and Porter subsequently flooded twice in May and September of 2019. They wound up suing Perry Homes, its subsidiaries and contractors, including LJA. Those cases recently settled.

Top Stories of 2021 in Review
Below are my personal picks for the top flood-mitigation stories of 2021.
The Fight for Funding
In 2019, Commissioners Court established “equity” guidelines that prioritized projects in Low-to-Moderate Income watersheds. Then this year:
Still no word from HUD on a possible direct allocation of $750 million. We may hear in January.
To help you follow this story, I make quarterly FOIA requests for Harris County Flood Control District spending and post the analyses on a dedicated funding page.
Sand-Mining Best Management Practices
Activists led by the Lake Houston Area Flood Prevention Initiative and the Bayou Land Conservancy petitioned the Texas Commission on Environmental Quality (TCEQ) to establish best management practices for sand mines in the San Jacinto watershed. We didn’t get everything we wanted, but we got a vast improvement over what we had. And the new BMPs may help reduce erosion that contributes to future floods in this area.
Relentless Development
Fueled by low interest rates and flight from city crowds during Covid, suburban and rural development surged in 2021. Flood-mitigation felt like an afterthought in many developments. We saw that with Colony Ridge in Liberty County. Colony Ridge clearcut wetlands, paved over floodplains and ignored county regs designed to reduce erosion.
In the Kingwood Area, the Laurel Springs RV resort took advantage of a grandfathering clause in permitting to build a detention pond one-half the size of current requirements. These represent just two examples of many.
After Harvey, we saw how such practices made flooding worse. How soon we forget!
Houston Housing and Community Development Meltdown
Houston’s Housing and Community Development Department, which was responsible for distributing more than a billion dollars in Harvey disaster relief funds, came unglued again this year. Last year, it sued the Texas General Land Office to keep money it couldn’t give away. This year, the Department’s Director publicly denounced the Mayor of Houston for trying to steer multi-family housing subsidies to the Mayor’s former law partner. The Mayor claimed ignorance of the partner’s involvement and announced a City Attorney investigation which never materialized.
Meanwhile, flood victims were victimized a second time. Bureaucratic bungling denied aid to people who deserved it.
World War II And Lake Houston Gates
May 9, 2021, was 1349 days after Hurricane Harvey ravaged Texas and the Gulf Coast. That’s the number of days it took the US and its allies to win World War II. But during that time we’ve had few victories in the fight against future flooding in the Lake Houston Area with the exception of dredging, So far, we’ve mainly completed studies. And many of those are still in the works.
For instance, the City of Houston has been studying ways to increase the release capacity of the Lake Houston Dam. Right now, the release capacity is one-fifteenth that of the gates on Lake Conroe. That makes it difficult to shed water quickly before and during floods. FEMA gave the City money to study the problem, but is still finalizing recommendations. The City hopes to make an announcement in January.
Lawsuits
The Lake Conroe Association had its lawsuit against the SJRA thrown out of court…with prejudice. The LCA hoped to prohibit the SJRA’s policy of seasonal lake lowering, which was designed to help protect the Lake Houston Area until other flood mitigation efforts could be put in place.
The Texas Attorney General is still suing the Triple PG Sand Mine in Porter on behalf of the TCEQ. There has been little movement on the case in the last 18 months. The mine’s owner changed legal counsel in July 2020. A TCEQ representative says the AG has not given up. The two sides are still in discovery.

Various lawsuits against the SJRA for flooding during Harvey are still working their way through the legal system.
Kingwood residents reached a settlement with Perry Homes, its subsidiaries and contractors this year over two floods that damaged hundreds of homes in Elm Grove and North Kingwood Forest during 2019. The incidents had to do with development of Woodridge Village, just across the Harris/Montgomery County line.
Woodridge Village
Harris County Flood Control District purchased Woodridge Village from Perry Homes in February this year and hired a contractor to begin doubling the current floodwater-detention capacity on the site. When complete, the additional capacity will help protect homes in Elm Grove, North Kingwood Forest and downstream along Taylor Gully.
Expansion of Dredging
After three and a half years of dredging in the San Jacinto West Fork, dredging has now moved to the East Fork. State Representative Dan Huberty secured $50 million earlier this year to extend the dredging program to other inlets around Lake Houston in the future.
Bens Branch and Taylor Gully Cleanouts
In Kingwood, HCFCD finished excavating both Bens Branch and Taylor Gully to help restore their conveyance. Through gradual sediment built up, both had been gradually reduced to a 2-year level of service in places. That means they would come out of their banks after a 2-year rain.
Subsidence
Years of fighting over subsidence between the Lone Star Groundwater Conservation District and Groundwater Management Area 14 came to a head earlier this year. LSGCD fought any mention of subsidence in Desired Future Conditions (DFCs) for Montgomery County. GMA-14 wanted to include it, but finally recommended allowing each groundwater conservation district to make a subsidence measure optional. Unlimited groundwater pumping in southern Montgomery County could tilt Lake Houston toward homes at the northern end of the lake. That’s because subsidence would be greater there than at the Lake Houston Dam by TWO FEET.
GMA-14 will take a final vote on January 5 on the final DFCs. You still have time to protest.
