Harris County, City of Houston Finally Close on Purchase of Woodridge Village Property

Today, almost two years after Perry Homes’ Woodridge Village development first contributed to flooding Elm Grove Village and North Kingwood Forest in Kingwood, Harris County and the City of Houston finally purchased the aborted, ill-conceived development.

Current plans are for the City of Houston to build a wastewater treatment plant on the northern portion. Harris County Flood Control District will use the southern portion to build a regional floodwater detention center. The latter should alleviate flooding problems adjacent to the development as well as other areas farther downstream on Taylor Gully.

Exact Plans for Additional Detention Capacity Not Yet Developed

It is not immediately clear how much additional detention pond capacity HCFCD will build on the property or where. However, on February 9, 2021, HCFCD hired an engineering company to develop preliminary plans.

A press release issued today by Harris County Flood Control said, “The next step is to undergo an engineering analysis to maximize stormwater detention volume, quantify the benefit to the community and determine project cost and funding. Additional community engagement will be scheduled to gather input from area residents on the proposed project and to present project alternatives.”

History of Flooding

The flooding problems began on May 7, 2019 when approximately 200 homes flooded from sheet flow coming from the development. Two to three times that number of homes flooded on September 19th, 2019 during Imelda.

Contributing factors included:

Eventually, Perry Homes, its subsidiaries and contractors managed to build five detention ponds, but their capacity still fell about 40% short of Atlas-14 requirements. Thus, the development would have posed a risk forever after had Harris County and the City not stepped in.

Photos of Property Just Purchased

Here are pictures of Woodridge Village taken on 3/3/2021 from several different angles.

More About the Sale

All of the 267.35 cleared acres fall within Montgomery County. But a provision within the 2018 Flood Bond allows Harris County to purchase land in other counties if it helps control flooding in Harris.

The Harris County Flood Control District and the City of Houston jointly purchased the property for approximately $14 million. The Flood Control District is using funds from the 2018 Bond Program (Bond ID Z-02) to acquire the land. The City of Houston contributed approximately $3.8 million dollars for the use and ownership of 73 acres on the northern part of the property.

Reaction from Government Officials

“This is a great example of government doing what government is supposed to do – listening to the people who live in those neighborhoods and working to protect them from future flooding,” said Harris County Precinct 4 Commissioner R. Jack Cagle, who pushed this project through against opposition in Commissioner’s Court.

Houston Mayor Pro Tem Dave Martin also worked tirelessly to make the deal happen. It involved trading City land to the County for flood control projects and getting the City to adopt the County’s flood control standards. “This purchase is integral for investment in the future of the Kingwood area as well as many homes along the county line. Collaboration like this is essential in providing a sense of security to residents who have endured so much uncertainty these last few years,” said Mayor Pro Tem Dave Martin.

Congressman Dan Crenshaw lauded Cagle, Martin, and community support. “This is an important step forward in building a more resilient community,” he said.

State Senator Brandon Creighton said, “This type of partnership and investment will make Kingwood and surrounding areas better protected.”

State Representative Dan Huberty complimented the City and County for working together. “This is a great example of different areas of government working together to achieve the best outcomes for local residents,” he said.

Additional detention ponds are not yet built, but this is a huge step forward. A big “thank you” and “whew” to all involved.

West Fork Still Running Siltier Than Spring Creek

After 3.5 years since Harvey and dozens of helicopter flights up and down the West Fork of the San Jacinto, it never ceases to amaze me. Despite sediment gage readings that say more silt is coming from Spring and Cypress Creeks than the West Fork, the West Fork appears siltier the vast majority of the time.

Misleading Data Used to Kill Meaningful Legislation

Here’s what the West Fork looked like today. Definitely siltier.

West Fork comes down from top of frame, Spring and Cypress Creeks from right. Photo taken 3/3/2021 from near US59 bridge, looking north.

Approximately 20 squares miles of sand mines line the West Fork. Problem is, the one sediment gage on the West Fork is upstream from virtually all of the mines. But most people don’t understand that. And that lack of understanding has allowed the mines to claim for decades that they are not the dominant source of sediment.

I’ve even heard miners testify on multiple occasions in the state legislature to that effect. That’s how they managed to kill best-practices legislation and minimum setbacks in the legislature in 2019.

When Brown & Root, the SJRA, City of Houston, Montgomery County, and Harris County Flood Control all cite the same misleading statistics, what’s an ordinary citizen to do?

Only a Sediment Gage Below Sand Mines Will Tell Whether This is Serious

To be fair, the engineers and hydrologists point out that the silt you see above and below may float out into Galveston Bay.

But I would also point out that:

  • The giant sand bar above didn’t exist before Harvey.
  • Neither did the multiple sand bars blocking the West Fork up to 90% (according to the Army Corps) after Harvey.
  • A misrepresentative gage placement, no matter how many times you repeat the sample in different studies, will always yield the same sampling error.
  • Most sediment moves during floods and far more sand is exposed to floodwater on the West Fork.

Finally, I would point out that the dikes of sand mines routinely breach and many mines routinely pump sediment laden water into the West Fork.

The point is: we will never really know what’s going on here until we get a gage downstream from the sand mines.

Photos of same location taken from different angles in previous months. In each case, the West Fork is siltier.

Time Of Essence

When I pointed out the data error caused by a misrepresentative gage location, the partners in the San Jacinto River Basin Master Drainage Study promised to re-evaluate claims they made based on the gage. The originally found, as did Brown & Root, that the vast majority of the sediment is coming from Spring and Cypress Creeks – based on the gage upstream of the sand mines. They also promised to consider installing a new gage downstream from the mines. But nothing has happened yet. And we’re already well into this legislative session.

Until changes are actually made to the study and a new gage is added, I fear the same miners may again repeat the same self-serving and misleading statistics in the legislature. That’s how they have killed bills that could help clean up our water more than once.

We’re now into the third month of the legislative session. And until the San Jacinto Master Drainage Plan consultants modify their findings, we’re all at risk. People will likely reference that study for another two decades, just as they have referenced Brown & Root’s. So this is important. Tick tock.

Huberty Files HB2525 to Create Lake Houston Dredging and Maintenance District

State Representative Dan Huberty filed HB2525 on March 1, 2021 to create a dredging district to perform ongoing maintenance dredging on Lake Houston. However, the boundaries of the District will be the boundaries of Harris County. As of March 2, Huberty’s bill does not yet have a senate sponsor, nor has it yet been referred to a committee.

Back in 2018, before the Army Corps finished its emergency dredging program, the Corps recommended a maintenance dredging program. Since then, the City has continued dredging with financial assistance from FEMA and a TWDB grant stemming from Huberty’s amendment to SB500, a senate appropriations bill in the 2019 legislative session. That amendment provided $30 million for additional dredging. The Harris County Flood Bond also provided money for additional dredging.

Need for Maintenance Dredging Recognized Decades Ago

Back in 2000, the Brown & Root Report, which came out of the 1994 flood, recommending maintenance dredging to prevent the kind of sediment buildups that contributed to Harvey flooding. But nothing was ever done until after thousands of homes and businesses flooded during Harvey.

Meanwhile, more sediment comes downstream with each flood. And that 2019 money won’t last forever. So ever since the last legislative session, Huberty has sought a permanent solution.

City of Houston has had three mechanical dredges working in the vicinity of the West Fork Mouth Bar for a year.

What HB2525 Does and Doesn’t Do

Here are the details of HB2525. The bill will:

  • Create a special purpose dredging and maintenance district whose operations are limited to Harris County and Lake Houston (including East Fork, West Fork and mouths of tributaries such as Rogers Gully, Luce Bayou and Ben’s Branch.
  • Maintenance will consist of the removal of floating debris, such as trees that clogged the waterways after Harvey.
  • The district will be governed by a board of seven.
  • Harris County Commissioners will appoint three directors.
  • Houston City Council will appoint three.
  • The County Judge and Mayor will jointly name the board’s presiding officer.
The District may:
  • Form interlocal agreements with other political subdivisions and corporate entities or persons to perform the work.
  • Seek grants of money, equipment or other resources to assist in its operations.
It may not:
  • Finance, develop or maintain a recreational facility.
  • Exercise eminent domain.
  • Perform the same functions as an overlapping conservation or reclamation district.

Financial Provisions

In addition to raising money from grants, HB2525 gives the District power to issue revenue bonds, but it may NOT levy a tax.

In formulating this bill, financing District operations received considerable discussion. Casey Christman, Huberty’s assistant, said, “We will have a committee substitute on this bill that makes several changes. But this bill would let the Lake Houston Dredging and Maintenance District (LHDMD) create individual interlocal agreements with each entity that purchases water, which at last count was about 68 organizations.”

“The terms of each agreement may differ (i.e. commercial vs. residential) but will outline how and where the fees are assessed. Also, LHDMD would be eligible to apply for grants or funds from other governmental entities, like FEMA or TWDB. Lastly, the new language will permit LHDMD to sell any materials collected. All options could help pay down bonds,” said Christman.

For the full text of the bill, amendments to it, and to track its progress through the legislature, see this page at Texas Legislature Online.

Thanks to Representative Dan Huberty for his persistence and leadership on this issue.
