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.
Commissioner Radack Responds
“Buffalo Bayou Not a Natural River”
Supporting Costly Engineering to Slow the Flooding River. Spending Money to Stop the River Slowing For Free.
Nov. 30, 2016
Updated April 23, 2017 — The Harris County Flood Control District reports that repair costs through March 2017 are $1.25 million. Terry Hershey Park remains closed until construction work is complete.
Harris County Precinct Three Commissioner Steve Radack called to comment on our article criticizing unnecessarily costly and destructive “repairs” to the north bank of Buffalo Bayou in Terry Hershey Park. The six-mile long park is in Precinct Three in far west Houston and Commissioner Radack is the boss there.
Radack’s main point, apparently in support of needlessly spending an excessive amount of money, was that Buffalo Bayou is not a natural river. Because the bayou is not natural, it “does not naturally meander.”
For background: the naturally meandering bayou in Terry Hershey Park was stripped and straightened in the 1940s and ‘50s. Last spring high waters from record rains and extended high flows from the federal dams immediately upstream ate away at the bank in places and damaged the asphalt hike-and-bike trail on the north side. We pointed out that this had occurred where the old meanders or bends were. The bayou, we said, was seeking out its historic meanders, adjusting to the flow.
Our point was that it would make more sense, in accordance with the most advanced river management practices across the country and around the world, to move the asphalt trail slightly away from the very edge of the water and allow the river room to move and restore itself. This would be far cheaper, prettier and more natural, and healthier for the bayou, the beneficial trees and plants and creatures that grow there, and for the water flowing through it to the bay. Doing that rather than hardening the bank in an artificial straight line is also less likely to cause flooding and erosion downstream and less likely to require expensive repairs all over again. It’s also federal policy.
But according to Radack, this doesn’t matter, because Buffalo Bayou is not natural. It’s not natural because the Corps of Engineers “controls the flow.” The bayou “only has water in it,” Radack explained patiently, if the Corps opens the floodgates. “The water comes from the reservoir system.”
Therefore, according to Radack, the bayou is “not natural.”
Is that all true? Beg pardon, but no.
But here’s a puzzle: Radack supports spending tens of millions in public funds to carve up the banks and engineer some two dozen in-channel detention basins on the bayou in Terry Hershey Park. (See below.) But he opposes allowing the bayou to carve out for free its own detention by widening and restoring its old bends. Instead he approves spending taxpayer funds to keep the bayou from doing that.
Does that make sense? Seems contradictory to us.
State of the Bayou
Downed Trees. New Channel. New Riprap. Washed Out Sidewalks, Beavers, and Turtles
But Some Banks Naturally Rebuilding
Does It Make Sense to Repair?
Sept. 1, 2016
Updated Sept. 11, 2016
You could not step twice into the same river. Heraclitus
We finally had a chance recently to float down beautiful Buffalo Bayou to see how things have changed. Our trip took us past Memorial Park in the middle of Houston. We also biked along the bayou through Terry Hershey Park far upstream in west Houston below the dams to see what was happening there.
The good news is that some of the high banks that had slumped in Memorial Park and the Hogg Bird Sanctuary during the Memorial Day 2015 flooding are naturally rebuilding.
The bad news is that the River Oaks Country Club has added more riprap to the south bank, hard armoring the bank with ugly, damaging concrete rubble, including where it should not be.
Nature’s Miraculous Way of Restoring. For Free.
Houston has had multiple record-breaking rains and flooding since the spring of 2015. When Buffalo Bayou overflows its high banks, as it did in the Memorial Day flood of 2015, the banks in places sometimes slump or slide away. This happens when the overflowing water seeps through the ground and saturates layers of sandy clay that liquefy, sometimes causing the bank to give way. Buffalo Bayou is 18,000 years old, and this has been happening for a very long time.
This natural tendency to slump is one reason why we think attempting to engineer these banks as proposed by the $6 million Memorial Park Demonstration Project won’t work. It’s also the reason why we think building and repeatedly repairing sidewalks at the bayou’s edge is wasteful and foolish.
It’s Not Dead Yet
Flood Control Still Pushing Costly, Destructive “Stabilization” Project on Buffalo Bayou
July 31, 2016
It’s a pointless, wasteful, ill-conceived, and maybe illegal project to rip up and raze trees and plants and wildlife habitat, dig up the banks, plug up tributaries, dredge and reroute the channel along one of the last natural stretches of Buffalo Bayou in Houston. This is a dreamy stretch of the river in the middle of the city, filled with beaver, otter, alligators, fish and flying creatures, and even edible plants. It flows for more than a mile past our great public Memorial Park, a natural detention area and significant geologic site that features very old high bluffs and sandstone formations. All of which would be obliterated.
And after almost three years of adamant public opposition, the Harris County Flood Control District is still promoting the project, which will cost the taxpayers at least $4 million plus, not including future costs of maintenance and repair.
It’s mystifying why they want to do this, why they think it would even work, why they don’t realize that the bayou would wash it away or that it would simply all slump away, as has happened in Buffalo Bayou Park downstream, where taxpayers are footing the ever-mounting bill for constantly repairing the banks dug up and stripped of trees and vegetation by Flood Control.
Do They Not Have More Urgent Problems?
Surely, the flood control district has more urgent problems that require our hard-earned tax money. Harris County is one of the most flooded places in the country. And this project, billed as a “stabilization” and “bank restoration” program, will do nothing to address flooding and could even make it worse. The county should focus on the hundreds of miles of channelized bayous and streams unwisely covered in now-aging concrete that should be restored to something more natural and beneficial.
The project, called the Memorial Park Demonstration Project, was first proposed in 2010 by the Bayou Preservation Association under then board chair, Kevin Shanley, landscape architect and principal with SWA Group, the firm responsible for the ugly, obtrusive bridges, collapsing sidewalks, poorly-functioning dog park and non-functioning faux Hill Country fountain and stream in Buffalo Bayou Park.
Can An Urban Stream Restore Itself?
Yes, With Room to Move. Free Rivers Are Healthier and Better for Flood Control

By Susan Chadwick, Executive Director, Save Buffalo Bayou
This article is adapted from a presentation made at the Southwest Stream Restoration Conference in San Antonio, Texas, on June 2, 2016.
Save Buffalo Bayou is a non-profit organization founded two years ago to fight a public project described as a “restoration” project on one of the last natural stretches of Buffalo Bayou as it flows through the middle of Houston, past 1,500-acre Memorial Park and another 15-acre public nature preserve, the Hogg Bird Sanctuary. Since then our organization has expanded into broader, related issues. But today’s topic is restoration.
Here are some of the most common responses I would get when I would say that this mile-long plus stretch of the bayou is natural, along with what were some of the most common defenses of the project.
The river’s not natural because the river changes.
It’s not natural because it’s been altered by high runoff from urbanization.
Trees fall into it.
It has terrible erosion problems. Look at those steep high banks!
It’s terribly eroded. Look at those sandy banks!
It’s eroding terribly. Sediment from the banks in Memorial Park washes up on the sidewalks of Buffalo Bayou Park we built downstream in the floodway right next to the river.
All that sediment carries bacteria. If we stop the banks from eroding so much sediment, we will reduce the bacteria. (Although sediment-laden Buffalo Bayou is less polluted than White Oak Bayou, which runs relatively clear and extremely foul due to being encased in concrete.)
And of course the big one: the river needs to be stabilized because it moves around.
Then there’s the argument, both implied and explicit, that prompted me to select this topic for presentation today: an urban stream cannot restore itself.
A Profound Misconception About How Nature and Rivers Work
All of those statements, of course, indicate a profound misconception about nature, about how a river works and how rivers benefit us.
A river is a living symbol of change. A living system. A dynamic process of nature that works for our benefit. Even the simple grains of sand work on our behalf to cleanse the water.
Radio Talk about Natural Flood Control
Flooding on the Air
June 14, 2016
Susan Chadwick, executive director of Save Buffalo Bayou, and John Jacob, board chair of Galveston Baykeeper, wetlands expert, and director of the Texas Coastal Watershed Program at Texas A&M, were on the radio today talking about bayous, streams, wetlands, floodplains, and natural solutions to flooding. The popular weekly Tuesday program, Eco-Ology, hosted by Pat Greer and H.C. Clark, aired from 3 to 4 p.m. on KPFT 90.1.
Among other things, we talked about proposals from the city and from the county and others to buyout property owners and widen and enlarge our bayous, creeks, and streams to handle increasing rains. This prospect might be alarming to those of us who recognize the importance of trees and vegetation along our waterways — for erosion control, cleansing our water, removing pollutants, slowing runoff, providing wildlife habitat, and many other life-sustaining functions, not to mention social benefits like we need nature to be sane.
But what if they didn’t bulldoze our waterways and widen them artificially? What if they removed the built structures and created parks and allowed room for our rivers and streams to move and adjust on their own by letting them flood into their natural floodplain?
This is in fact the latest thinking in flood control worldwide. Room for the river to move. Even in the Netherlands they are tearing down their big gates and dikes, letting the water in while raising the land where people live and work. Even in Missouri.
A lot cheaper, more cost effective, and more beneficial overall.
Reminder: The Threat is Still Alive
Operation Save Buffalo Bayou II
March 14, 2016
Okay, so we harshed the mood a little with our small, silent reminders that regatta contestants were paddling through a historic natural area still threatened with destruction.
“Thanks for polluting my day,” yelled one paddler in the crowd of hundreds of Buffalo Bayou boaters playing loud music and stopping to pee in the woods. We were watching from the sandy bank of the lovely middle meander, forested with young willows and box elder that would all be cut down, the meander filled, graded, and planted with grass.
The event was the 44th Annual Buffalo Bayou Regatta on Saturday, March 12. And once again we hung our beautiful Save Buffalo Bayou banner (Night Heron by Houston artist Frank X. Tolbert 2) from the railroad bridge and set out small white signs alerting participants to the fact that the wild stretch they were passing through would all be bulldozed under a plan proposed by the Harris County Flood Control District and the Bayou Preservation Association (BPA).
The project, known as the Memorial Park Demonstration Project, demonstrates exactly the wrong thing to do. (See Buffalo Bayou Park and Fonteno Park.) It would raze most of the trees and vegetation along more than 1.25 miles of the 18,000-year-old bayou as it passes by Memorial Park and the Hogg Bird Sanctuary. These trees and vegetation and even the sand are part of the riparian zone, essentially wetlands, that hold the banks together, cleanse and filter the water, slow and absorb storm runoff, provide wildlife habitat, among many other important ecological functions. The $6 million “natural channel design” project, financed with $4 million in county and city taxpayer funds, would dredge and reroute the bayou and plug tributaries, obliterate ancient cliffs, destroy 250,000-year-old sandstone formations, and fill in our lovely meander (a natural detention area). Killing the bayou’s ecosystem in the name of “restoration.” And landscape design.
And no, contrary to rumors, the project, although holding its breath, is not dead. The Army Corps of Engineers is still deciding whether to issue a permit for the project, which is otherwise a violation of the federal Clean Water Act.
The Bayou Preservation Association first formulated the plan for the project in private meetings in 2010 and former BPA president Kevin Shanley, then a principal with the landscape architecture firm SWA Group, was the primary promoter. SWA Group is the design firm that is also responsible for the landscape design of Buffalo Bayou Park downstream east of Shepherd.
So this is why we had signs up warning of landscapers lurking. In Buffalo Bayou Park downstream, we set out a few signs pointing out that landscaping has washed away (several times actually) and that removal of vegetation has caused erosion problems, and that repairs were $$$$ (paid with City funds). Yes, we were bad! Those signs did not last long, however.
Upstream around Memorial Park and the Hogg Bird Sanctuary our signs pointed out where beavers live, where banks were being naturally rebuilt by the bayou, and the Pleistocene bluffs that would be graded into a slope. Interestingly, the bayou, during and after the Memorial Day flood in 2015, has already graded the lower banks of those steep bluffs into a slope.
The River Oaks Country Club is theoretically a one-third partner in the demonstration project and owns the entire south half of the project reach. But in the meantime the club in two places has armored its banks with ugly concrete riprap, one of the most environmentally destructive methods of erosion control (pdf), and also, we allege, in this case illegal, as we contend that much of the riprap was placed in public waters, also a violation of the Clean Water Act.
The club, unfortunately, is having erosion problems on its high banks in those places because it cut down a lot of trees and extended the mowed and watered grass of its golf course up to the edge of the banks.
We put out signs pointing out that riprap damages the ecosystem and is part of the problem, not the solution.
But we’re glad people had fun, enjoyed the bayou, and picked up some of trash.
Maybe they’ll think about the future of the bayou.
And special thanks to river guide Tom Helm and to Richard Hyde for extra long duty putting out and picking up our banner and picking up our signs.
Support Your Forest on Buffalo Bayou
Annual District G Meeting with City Officials Thursday, March 3
March 2, 2016
Citizens concerned about our forests on Buffalo Bayou will want to attend the annual District G Capital Improvement Plan meeting tomorrow evening, March 3, 2016. The meeting starts at 6:30 p.m. in the Stratford High School Auditorium, 14555 Fern Drive, and features the district’s new city council member, Greg Travis, who was elected to City Council District G last November.
Capital Improvement Plan meetings “afford citizens an opportunity to learn, voice their concerns and address their respective City Council Members and City of Houston officials regarding project planning and delivery,” according to a statement on Travis’ website.
District G extends along Buffalo Bayou from Shepherd Drive to Barker Reservoir in far west Houston.
Members of Save Our Forest, which was successful last year in persuading the City of Houston to drop its plan to raze forest in Terry Hershey Park for a stormwater detention basin, are urging citizens to “show your support for the forest to our new City of Houston administration.”
“We now have a new city council representative, a new mayor and a new [Public Works and Engineering] director since we began our campaign to Save Our Forest,” wrote community activist George Crosby in an email. “It is important that they know how much you care about Buffalo Bayou.
Detention Alternatives Without Destroying Forests
“Last year there were two major rainfall events which caused structural flooding in Houston. Regional detention alternatives that can reduce local flooding without having to destroy the forested areas of Buffalo Bayou are not happening. Cooperation between the City, County and Federal governments is required for a successful regional detention initiative.
“A cooperative inter-governmental effort begins with the City of Houston understanding our support for this approach. Please help us give emphasis to Save Our Forest,“ wrote Crosby.
The public forests of Buffalo Bayou are still threatened by a Harris County Flood Control District plan to build some 24 detention basins on both banks of Buffalo Bayou in Terry Hershey Park.
The flood control district is also waiting for a federal permit to raze the forest along more than 1.25 miles of one of the last natural stretches of the bayou as it flows past Memorial Park and the Hogg Bird Sanctuary.
It makes no scientific sense to destroy forests to create detention basins. Forests provide valuable natural detention by slowing, absorbing, and deflecting rainwater, in addition to many other valuable ecological services, including cleansing and filtering the water and protecting against erosion.
In October of 2015, the Obama administration issued an executive order directing all federal agencies to incorporate the value of ecosystem services in their decision-making.
In addition, the Harris County Flood Control District is obligated by state law to conserve forests. (PDF. See page 6.)
Buffalo Bayou Doesn’t Like Sidewalks, It Seems
Buffalo Bayou Park Was Supposed to Be More Stable
Nov. 16, 2015
Updated Nov. 17, 2015
Update: “Endless Repairs: Buffalo Bayou Sets Its Own Terms,” Houston Chronicle, Nov. 20, 2019
Well, we can’t help but wonder if constantly scraping and repairing the sidewalks, forever reinforcing the collapsing banks somehow, and repeatedly replacing the trees and landscaping is fully covered by the $2 million annual maintenance budget for Buffalo Bayou Park paid by Houston city taxpayers.
The popular, much praised, and much needed park on the banks of the bayou between Allen Parkway and Memorial Drive is suffering from some serious erosion problems. And that matters to us not just because of the expense and waste. This $53.5 million project, a boon to adjacent property owners and those who live and work nearby, was touted as a successful example of what the Harris County Flood Control District, egged on by the Bayou Preservation Association, wants to do to our healthy, historic wild bayou further upstream in and around Memorial Park. Buffalo Bayou Park was supposed to be more stable! The flood control district calls it Natural Stable Channel Design, but it always looked to us like they were doing everything you’re not supposed to do on the banks of streams: dig up the banks, run heavy equipment over the banks, remove the trees and vegetation (yes, they did a lot of that), build concrete and asphalt sidewalks on the banks, plant grass and mow it.
Let’s Work With Nature, Not Against It
Once you’ve done all that, and the banks and channel start falling apart, it’s pretty difficult to fix it. Best to let the bayou do what it will do anyway. (And eventually the bayou will rebuild and replant it all.) But it seems unlikely that the City and the Buffalo Bayou Partnership are going to sit back and patiently let millions of dollars worth of sidewalks, lamps, and bridges collapse into the bayou. Can they stop it? Time will tell.
In the meantime, it does make one wonder about all those concrete trails they are carving out of the banks and floodplains of the bayous for the Bayou Greenways project. A nice idea, but is that going to work?
Here’s what we’re talking about. What this slide show of photos of Buffalo Bayou Park between Shepherd and Montrose taken on Nov. 15, 2015.
Film: Letting the River Heal
Learning to Respect A River’s Natural Process
October 18, 2015
“We have to be patient,” says Steve Nelle, Natural Resources Conservation Service, retired.
“Nature’s going to recover that area at her own timetable in her own way. It’s best to accommodate that natural process.”
Watch this moving and informative 14-minute documentary about a river’s natural process and Best Management Practices for protecting against erosion and preserving a river’s important role in cleansing our water, slowing storm water and runoff, and providing wildlife habitat.
All of this applies to Buffalo Bayou as well as our other bayous, creeks, and streams in Harris County. Even a small riparian buffer of native trees and vegetation a few feet wide is important for our waterways and the cleanliness of the water flowing through our neighborhood streams and into our bays and oceans. But on Buffalo Bayou, especially as it flows past Memorial Park, we are fortunate to have room for the river to move. Letting the river be a river is the most current scientific thinking on river management, even in cities. A dynamic river creates the most beneficial and biologically diverse environment.
This lovely, short film was made about the Blanco River and the impact of the 2015 Memorial Day flood on Wimberly, Texas. We can all learn from it.
