#60 Recommendation to execute a Partnership Agreement with TXDoT for preliminary engineering and environmental review for a railroad grade separation on Hamblen Road, from Loop 494 to Laurel Springs Lane.
#83 Authorization to negotiate an interlocal agreement for a partnership project with the SJRA, Humble, and five utility districts for a feasibility study and conceptual design on the Spring Creek Watershed Flood Control Reservoirs.
This would improve traffic flow and expand the development area of the 90-acre park that will serve as a key anchor park along the Spring Creek Greenway trail. The current two-lane asphalt segment of Hamblen Road runs across the Union Pacific Railroad track through the middle of the proposed park. Plans include rerouting the new segment diagonally from Loop 494 at Sorters-McClellan Road to Laurel Springs Lane and upgrading it to a four-lane concrete with a bridge over the railroad track. The previous Hamblen Road segment could then be repurposed to serve park visitors. If approved, construction will not affect the park’s cypress ponds.
The bridge would also provide an evacuation route from Kingwood in the event of a railroad accident. UP plans to increase the length of its trains making a bridge more important than ever. In the event of a derailment, the longer trains (without the bridge) could block all Kingwood exits to US59.
Also, the current intersection is one of the most dangerous in Kingwood. Danny Sullivan, of Sullivan’s Automotive, says he tows vehicles almost daily from this stretch of road. There are a number of blind turns with people trying to cut across multiple lanes as traffic zooms north off the San Jacinto bridge.
Spring Creek Reservoirs: Feasibility Study, Conceptual Design
Additional upstream detention is one of the three main legs of the Lake Houston Areas flood-reduction strategy. Upstream detention would reduce the inbound flow; dredging is restoring conveyance of the West Fork; and additional gates on the Lake Houston Dam will help eliminate backups.
In 2018, Lake Houston area leaders identified a three-pronged strategy to help mitigate flooding. They dubbed it the “Plea for DDG.” Additional dredging, detention, and gates. Since then, dredging and gates have garnered the most media attention. Yesterday, however, we received some good news regarding additional upstream detention.
HCFCD Buys First Part of Raveneaux Club
The Harris County Flood Control District (HCFCD) closed on the purchase of the Raveneaux Country Club on January 30, 2020. The final purchase price for 27.63 acres of land was $11,496,427.20 which is also the current appraised value for the property.
The final deal includes a leaseback allowing the Country Club to continue operating for up to one year.
The Flood Control District will begin discussions with the Cypress Forest Public Utility District in February regarding an agreement to acquire the remaining 206 acres that primarily make up the golf course. HCFCD intends to use the land for a future flood risk reduction project in the Cypress Creek watershed.
Benefit to Cypress Creek AND Lake Houston Area
That project could help the Champion Forest area where hundreds of homes flooded during Harvey and other recent storms. It could also help the Lake Houston Area. By reducing and delaying floodwaters coming down Cypress and Spring Creeks, it could help offset releases from the Lake Conroe Dam.
The Flood Control District realizes that community interest in this matter is very high. At this time, project specifics have not been determined. The Flood Control District will have community engagement meetings to solicit input and ideas about the future project.
Some feel the loss of the Club could adversely impact surrounding home values. However, the Club had reportedly been losing close to a million dollars per year for several years and was no longer financially viable.
In a special web page devoted to the acquisition, HCFCD says it cannot predict how property values will change as a result of this proposed project. However, HCFCD “knows that properties with a lower risk of flooding have a higher value than properties with a high risk of flooding.”
First Part of a Larger Solution
It is unlikely that HCFCD will find one undeveloped tract of land large enough to reduce flooding in the Lake Houston Area by itself. Acquiring a combination of smaller tracts such as Raveneaux will likely be necessary. Yesterday, HCFCD took the first step toward a larger solution.

As we enter 2020, keep your eyes on these stories.
Elm Grove Lawsuits and Mitigation
In 2019, Elm Grove flooded twice with runoff from the Perry Homes/Woodridge Village development in Montgomery County. Hundreds of homeowners sued Perry Homes’ subsidiaries (PSWA and Figure Four Partners) and their contractors.
On 12/17/19, attorney’s for the plaintiffs filed a fourth amended petition. Since the original filing, plaintiffs have named Double Oak Construction and Texasite LLC as additional defendants.
The judge set a jury trial date for July 13, 2020. To date, Perry Homes has done nothing to reduce the threat of flooding from their job site.
That brings us to the subject of mitigation.
What can be done to restore the safety of residents?
Perry Homes has demonstrated no interest in reducing the threat to downstream flood victims.
Protecting homeowners will require massive intervention from an outside source. But who? And how?
I recently learned of two new developments in the Ben’s Branch watershed.
A developer intends to build 18 acres of apartments where the woods adjacent to the new St. Martha Church now stand.
Another developer intends to build hundreds of homes on tiny lots on an 80-acre site just north of St. Martha’s.
These two projects represent dozens of others gobbling up farm and forest land in southeast Montgomery County.
Businesses such as the St. Martha School and Kids in Action already flooded twice this year. So did dozens of homes along Ben’s Branch.
Additional upstream development has the potential to make flooding even worse. This is like death by a thousand cuts. Residents just don’t have the time or energy to monitor each development to ensure that owners follow rules and regulations for wetlands, floodplains, drainage, etc. Neither evidently does Montgomery County. Which brings us to…
Montgomery County Standards and Enforcement
Montgomery County competes for development by touting its lack of regulations. That’s a huge problem for downstream residents.
Montgomery County still bases flood maps on data from the 1980s.
Large parts of the county remain unmapped for flood hazards.
The County last updated its Drainage Criteria Manual in 1989.
Developers ignore many provisions within it.
County Commissioners voted to leave loopholes open that allow developers to avoid building detention ponds.
The County even paid an engineering company to investigate itself for its role in the Elm Grove Disaster.
You get the idea. If you thought some benign government entity watched over new developments to protect downstream residents, think again. Below you can see the 80-acre site I mentioned above.
Note how it was covered in wetlands. Developers did not ask permission from the Corps to remove them. They just decided on their own that they didn’t need to ask.
Below, you can see how virtually half the site is in a flood zone or floodway.
Here’s how it looks in Google Earth. Developers have already cleared the site.
Developers intend to build high-density homes in the floodplains. They will also build their detention pond in the floodway. Those hazard areas will likely expand when and if the County incorporates new Atlas-14 data into their flood maps.
None of this seems to bother the leadership of Montgomery County. And that’s a bigger problem than any one development.
In 2020, expect more focus on the decision-making process and decision makers who have created a permissive culture of indifference to flooding problems.
During Harvey, the release of 80,000 cubic feet per second from Lake Conroe added to downstream flooding. The goal: to find enough upstream detention capacity to help offset future releases. The San Jacinto River Basin Study will examine that possibility. It’s unlikely that one reservoir will provide enough capacity. However, multiple smaller reservoirs may.
The study partners will release their results in the second half of 2020. Land acquisition and construction could take several additional years.
Luckily, State Representative Dan Huberty sponsored legislation that allocated another $30 million. The Harris County Flood Bond allocated $10 million. The City of Houston allocated $6 million. Plus two more grant requests are still pending that could increase the total even more. And a disposal site for the material has already been permitted.
Last week, Harris County commissioners voted to proceed with additional dredging. Project managers are studying the most cost effective ways to proceed. We should see more dredging soon.
This money could also be used on the growing mouth bar of the East Fork.
State Highway 99 Extension
The extension of the Grand Parkway (State Highway 99) east and south to I-10 will open up vast new expanses of forest and farmland to high density development. The biggest threat will be to the East Fork watershed as construction moves through southeast Montgomery County and the northeast tip of Harris County into Liberty County.
Those are my predictions for the biggest stories of 2020. There’s a lot of good news in the forecast and much to remain vigilant about. Life seems to be a constant struggle between those who would increase and decrease our margin of safety when it comes to flooding.
