Reminder: Buffalo Bayou Watershed Flood Bond Meeting July 30
Also Barker Reservoir Meeting on Aug. 1
July 23, 2018
The Harris County Flood Control District and members of county commissioners’ court continue to hold meetings around the county to present proposals for projects attempting to reduce the hazard of flooding.
The meeting about projects proposed in the Buffalo Bayou watershed will be held on Monday, July 30, from 6 to 8 p.m. at the Memorial Drive United Methodist Church, 12955 Memorial Drive in Houston. A meeting to present projects proposed for the Barker Reservoir watershed is scheduled for Wednesday, Aug. 1, from 6 to 8 p.m. at Memorial Parkway Junior High, 21203 Highland Knolls Drive in Katy. Buffalo Bayou flows from its headwaters near Katy into and through Barker Dam.
The projects are to be funded with the proceeds of a $2.5 billion bond issue should the voters approve on August 25. The bonds would be issued over a period of ten to fifteen years, according to the flood control district, and repaid through a property tax increase of no more than two-three cents per $100 of home valuation. Homeowners with an over-65 or disabled exemption and a home worth $200,000 or less would not pay any additional taxes, according to the district.
Most of the projects proposed are projects that had long been planned. For instance, a controversial project to remove forest and excavate basins to capture and temporarily hold overflow on the south bank of Buffalo Bayou in Terry Hershey Park is listed with a $10 million cost estimate. The project in its initial stages would allegedly create 60-100 acre-feet of temporary storage alongside the bayou. The linear detention, siphoning flow out of the bayou, is planned to compensate for eventual additional City of Houston drainage into the bayou from neighborhood streets.
Barker and Addicks dams both drain into Buffalo Bayou, and overflow from Cypress Creek on the rapidly developing Katy Prairie in northwest Harris County also drains into the overburdened Addicks Reservoir, adding to the pressure of runoff into Addicks and the bayou.
Other than the Hershey Park detention project, some $21 million is slated for a new detention basin north of John Paul’s Landing on Upper Langham Creek, which drains into Addicks.
However, most of the projects listed for these watersheds mainly focus on repairing channels and improving conveyance – making more stormwater flow faster into and through the reservoirs. This has the potential to cause more problems and more flooding. Modern practice elsewhere is to focus on slowing the flow, making room for the river with wider floodplains. We would hope for more money to be spent on land aquisition, buyouts in floodplains, preservation of undeveloped land, forest, wetlands, prairies, and riparian vegetaton; creation of green space, restoring meanders, and programs to encourage slowing of rain runoff beginning with individuals and neighborhoods.
There are also funds proposed to be used in collaboration with Army Corps of Engineers, which owns and operates Addicks and Barker, to evaluate the effectiveness and operation of those 70-year-old dams.
A complete list of projects can be found on the flood control district’s website. The website also offers a way to make comments about the projects.
The meetings are not set up for the public to engage officials or voice opinions. They are informative only – with numerous stations staffed by flood control personnel to explain projects. However, paper and pencils are provided for citizens to write comments.
Engineers Caused the Flood That Led to Creation of Flood Control District
A Fact-Based Response to “Engineers’ View” in the Texas Tribune
March 6, 2017
A few weeks ago the Texas Tribune published an editorial comment written by engineers Michael Bloom and Steve Stagner responding to the excellent investigative work on flooding in the Houston region, “Boomtown, Floodtown,” published by the Tribune and ProPublica on Dec. 7, 2016. See our summary of the report here.
In their TribTalk editorial “Boomtown, Floodtown Reconsidered, An Engineer’s View,” Feb. 6, 2017, Bloom and Stagner repeat a couple of erroneous statements commonly used by representatives of the Harris County Flood Control District in support of the district’s shaky position that paving over the prairie, i.e. development, is not contributing to flooding.
According to this point of view, our native tallgrass prairie and its associated wetlands are hardly better than concrete when it comes to slowing and absorbing rainwater. These deep-rooted grassland prairies, with water-absorbing root systems that can reach 12-15 feet into the ground or more, once existed around and upstream of Buffalo Bayou, in Katy, west of Houston, for instance, source of Buffalo Bayou, as well as up and down the coastal plain. Practical people are trying to preserve and restore what remains.
In support of their argument, Bloom and Stagner summon up a point commonly made by members of the local engineering community: that the 1935 flood on Buffalo Bayou that devastated downtown Houston and led to the creation of the Harris County Flood Control District happened even though the Katy Prairie way upstream was then a big natural tallgrass prairie.
This argument is wrong on two points. Read why in this fact-based response by Save Buffalo Bayou to an “Engineers’ View” published as a comment in the Tribune’s TribTalk.

Flying Down Buffalo Bayou
The Mother Bayou from Beginning to End
June 24, 2016
“Visualizing Nature, The Art and The Science” was the title of a class at Rice University taught this spring by photographer Geoff Winningham, professor of photography in the Art Department and holder of the Lynette S. Autrey Chair in the Humanities, and by Adrian Lenardic, professor of geophysics and planetary science in the Department of Earth Science. One theme of the class was the visual and scientific aspects of Buffalo Bayou.
Connor Winn was a student in that class, and he made a lovely fourteen-minute video using a flying drone that follows our Mother Bayou from its quiet beginnings west of Houston. The film allows us to watch the bayou evolve from its source near Cane Island Branch, a creek, one of many feeding into the bayou, that runs through the town of Katy, which in the 1800s was known as Cane Island, named after the creek filled with cane. We see the bayou growing into the mighty ship channel and joining the San Jacinto River at Burnet Bay, part of Galveston Bay, near the San Jacinto Monument just upstream of Baytown.
Proposed Roads to Damage Katy Prairie Preserve
Urgent Notice of Public Meeting and Comment Deadline
May 1, 2016
Updated May 3, 2016
The Katy Prairie Conservancy has announced that the Harris County Engineering Department has corrected the email link for commenting on proposed changes to the Harris County Major Thoroughfare and Freeway Plan that will damage the Katy Prairie.
The correct email address is:
Update May 8, 2016
The comment period has been extended until May 13.
The Katy Prairie Conservancy has sent out an urgent notice of a Harris County plan to build new roads in and around the Katy Prairie Preserve. The preserve is a nonprofit land trust project to restore and protect historic wetland prairie in Waller and western Harris counties.
Buffalo Bayou originates in the Katy Prairie. Prairie wetlands, rapidly being destroyed and paved over by development, are vital for clean water and flooding mitigation, as are forested riparian zones along the banks of streams such as Buffalo Bayou and its tributaries.
When, Where, and How
The Harris County Engineering Department is holding a public meeting Monday, May 2, 2016, on proposed changes to the Major Thoroughfare and Freeway Plan (see particularly pages 25 through 29) that will “degrade the Katy Prairie Preserve System,” according to the conservancy.
The meeting takes place from 5:30 to7:00 pm at the Hockley Community Center, 28515 Old Washington Road, in Hockley, Texas.
The conservancy urges that if you cannot attend the meeting, please submit your comments in writing by May 13, 2016, via email to email@example.com or by mail to:
Harris County Engineering Department
10555 Northwest Freeway, Suite 120
Houston, Texas 77092
Attn: Fred Mathis, P.E.
The conservancy says that while Harris County is proposing to dispense with parts of the one-mile road grid through some of the preserves, the county also recommends constructing new roads in sensitive and/or inappropriate areas.
Here are some of the conservancy’s main objections:
- In general, the plan does not effectively take into consideration the importance of the Katy Prairie preserves in reducing flooding, improving water quality, providing wildlife habitat, and offering recreational opportunities for the residents of the Greater Houston area. Roads should go around the Katy Prairie preserves and not through them. Roads can move, nature cannot.
- KPC does not support the new proposed east-west road through the upper third of the Warren Ranch; it will cause fragmentation and impair ranch operations.
- KPC does not support the new proposed north-south road through the conservation easement lands owned by KPC’s conservation easement donors; this land provides sensitive habitat and flood protection as well as other environmental benefits. It should be protected.
- A number of the proposed new roads, if built, would be under water during flood events if the most recent flood event is any indication of where floodwaters go on the prairie.

No Changes in Operation of Buffalo Bayou Dams
Release Rates May Be Looked At in Future
March 13, 2016
It was a dark and stormy night. Thunder boomed and heavy rain pelted the roof as a small group of us sat nervously in the middle of the rising Addicks Reservoir in far west Houston listening to the district commander of the Army Corps of Engineers tell us Addicks and Barker dams are safe.
Flanking Col. Richard Pannell last Wednesday, March 9, was a panel of officials from the Corps’ Galveston District office, as well as representatives from the Harris County Flood Control District and Granite Construction, the company awarded the $71.9 million contract to replace the leaky conduits in the 70-year-old earthen dams. The audience was a small crowd of about thirty hardy citizens who had braved the heavy traffic and heavy rain and managed to find the Bear Creek Community Center in the middle of a dark, wet forest despite the wrong address in the Corps’ public notice.
Col. Pannell made a thorough and convincing presentation of the history of the dams, the current problems, and what is being done about them. Among other work, the conduits in the two dams will be entirely replaced by new conduits in separate locations. This process will take about three years. He emphasized that the dams were in no immediate danger of failing and explained that the dams are labeled “extremely high risk” because of the potential consequences to Houston, the nation’s fourth most populous city, in the unlikely event that the dams failed.
Dams Operating Normally Despite Leaks
There were several questions about the capacity of the dams and the impact of repairs on the rate of future releases of water impounded behind the dams. The pattern of extended high releases and rapid drops has been criticized for damaging property on the bayou and killing trees and vegetation that control erosion.
After the enormous Memorial Day storm last year, the Corps began releasing impounded stormwater at 3000 cubic feet per second (cfs) for the first time. Normally the release rate is limited to 2000 cfs as measured by the Piney Point gauge. The Corps does not release water from the dams during a rain event, and the high releases began on June 1 and continued for ten days, finally dropping on June 12. The banks were already saturated from the storm, and the damage from the extended high flow was plainly visible up and down the bayou.
Engineers Vote for More Work for Engineers on Buffalo Bayou
Developers Eager to Pave More Streets and Parking Lots
Oct. 21, 2014
Raise your hand if you ever heard of the Harris County Flood Control Task Force.
Try looking on the Internet for any mention of this 31-member semi-secret committee and you’ll find almost nothing except for an occasional reference in someone’s bio and a brief note on the website of the Bayou Preservation Association. Founded in the 1970s to create “a community collaboration of engineers, developers, and interested citizens,” according to the BPA, the task force is now mostly a collaboration of engineers and developers, as is the BPA.
County Judge Bill Elliot is reported to have said at the time: “How can Harris County government adequately protect homes and businesses from the hazards of flooding and facilitate economic development, while at the same time preserving the God-given resources we have that are still in their natural state for the present and future enjoyment of our citizens?”
Last Tuesday, Oct. 15, a county task force committee looking into that question voted 5-1 in favor of spending $6 million to wreck the last natural stretch of Buffalo Bayou in Houston, a perfectly healthy 1.5 miles of wild bayou flowing in and around our Memorial Park. The project would destroy riparian forest crucial to the health of our water, to erosion and flood control. Riparian zones are increasingly being recognized as wetlands that should be federally protected for our own health and survival.
On Monday, Oct. 27, 2014, at a public meeting in the Harris County Flood Control District headquarters, 9900 Northwest Freeway, the full flood control task force will be voting on whether to go ahead with the controversial project. Update: The chairman of the task force, Ranney McDonough, said in phone call late Thursday afternoon to Save Buffalo Bayou that the doors of the meeting will be closed and the public will be turned away. But we are going anyway.
The flood control district declined to provide us with the names of the current members of the full task force, suggesting we contact the Harris County Commissioners’ Court since the commissioners’ court created and appoints the task force. No response to those emails by press time. Update: Courtesy of one of the members, we now have a reasonably current list of the members of the task force. And generally we know that of the 31 positions approved by the commissioners, about nine seats go to engineers and architects, another eight go to developers and builders, another two go to business groups, three or four go to government agencies, and another seven go to environmental or civic groups or individuals. Several positions are empty.
We will do our best to provide their contact information. These task force members need to be contacted and informed. Please let them know of your opposition and why. In addition, please note that Harris County Precinct 4 Commissioner Jack Cagle, who represents Memorial Park, is up for election on Nov. 4.
Not In. In a Meeting. On the Other Line.
As of this writing, it is unknown how many of the five task force committee members who voted in favor of the bulldozing project have seen this part of the bayou. We’ve made fruitless calls and left messages and talked to one engineer on the committee who voted in favor of bulldozing and channelizing the last wild bayou. He’d never seen the area to be destroyed; he thought there was no vegetation there.
