Wasting Money the Old-Fashioned Way
Costly Bayou Repairs Do More Harm Than Good, Won’t Last
Nov. 21, 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.

From a distance you could hear the monstrous roar of the heavy equipment in the woods. Following deep, wide tracks smashed into the bare dirt along the bank of Buffalo Bayou, passing large cottonwoods apparently cut to make way for the big equipment, we came across a scene of troubling destruction.
A gigantic articulated 30-ton dump truck with six massive wheels was slowly rolling towards us with a large load of fresh dirt and dripping mud dug up from the bayou bank. Further along a 60-ton excavator on tracks sat on the very edge of the bank, expertly swiveling back and forth, scraping up the dirt bank and dumping it into the truck, scooping up loads of white limestone rock and dropping it in a layer where the excavated bank once was.
We’d seen the eroded bank before the “repairs” began. This damage was far worse.
It didn’t have to be this way.

But Some Banks Naturally Rebuilding
Does It Make Sense to Repair?

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.
This map prepared by the Harris County Flood Control District shows the areas to be excavated (yellow) and filled (orange) in the proposed Memorial Park Demonstration Project. Note also the rerouting of the channel. Memorial Park and the Hogg Bird Sanctuary, including a tributary, are on the north, with houses in between. The entire south bank is River Oaks Country Club golf course.
Can An Urban Stream Restore Itself?
Yes, With Room to Move. Free Rivers Are Healthier and Better for Flood Control

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.
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.

Float In The Air Down Buffalo Bayou With Houston Photographer Jim Olive

Travel down the remarkable historic stretch of our 18,000-year-old bayou proposed for “restoration” by the Harris County Flood Control District and the City of Houston. The $6 million project, violating virtually every Best Management Practice for riparian areas, would pointlessly destroy and rebuild over 1.25 miles of a naturally-functioning bayou as it flows past Memorial Park and the Hogg Bird Sanctuary on the north and the River Oaks Country Club on the south.
Photos taken on October 2, 2015. Thank you, Jim Olive!
This massive new drainage outfall on Buffalo Bayou at Woodway, soon to be once-again a public boat launch, is not in the project area targeted for "restoration" by the proposed $6 million Harris County Flood Control project. But this formerly forested area in Memorial Park, destroyed for a $1.3 million City "erosion control" project, is for many the beginning of a float trip through the threatened historic natural area in the park.

Update on Puzzling Project to Bulldoze Wild Buffalo Bayou
Damaging, Expensive, Contradictory Plan Still Threatens
Conflicts Still Apparent, Purpose Still Unclear
No Permit Yet
October 8, 2015
The Harris County Flood Control District has responded to largely critical public comments to the Army Corps of Engineers about Flood Control’s misguided project to destroy one of the last natural stretches of Buffalo Bayou in Houston, a most remarkable asset to have in the middle of a city. The Corps is reviewing the Flood Control District’s responses, says Jayson Hudson, who has been the Corps’ Galveston District project manager for the permit application.
Flood Control must apply for a permit from the Corps of Engineers because the Clean Water Act requires the Corps to ensure that projects on federal waters do not damage the health of our waters. Federal waters are defined as navigable streams (Buffalo Bayou) up to the Ordinary High Water Mark, their tributaries and adjacent wetlands, all of which form the great living veins and arteries of our limited water supply. Some studies argue that all riparian areas , the highly biologically diverse natural gardens and forests along stream banks so vital for clean water, should be considered protected wetlands .
This beautiful meander, a natural storm water detention area, would be filled in and graded, the woods and high cliffs destroyed, and the entire floodplain area obliterated by a permanent road. Aerial photo on Oct. 3, 2015, by Jim Olive
The Piles of Concrete Came Down
Country Club Armors High Banks with Chunks of Rubble
August 12, 2015
For months we watched with suspense the towering piles of concrete riprap. They hung heavily over the edge of a high bank on the south side of Buffalo Bayou near the downstream end of one of the loveliest natural stretches of the bayou in the city. It’s a long stretch of the bayou that the Harris County Flood Control District wants to bulldoze and “restore” to a “more natural state,” so we were apprehensive.
A row of small telltale colored flags had first appeared near the waterline here and upstream at the upper limit of the area targeted for flood control’s highly destructive Memorial Park Demonstration Project.
The south bank of the nearly 1.5 mile project area is owned by the River Oaks Country Club, which is a one-third partner in the $6 million public project initiated and promoted by the Bayou Preservation Association. The club, which has nearly completed a renovation of its golf course on the bayou, had long threatened to armor its banks with riprap if the “stabilization” project didn’t go through.
And now the club has carried through on its threat, laying down black plastic sheeting on the steep banks at those two locations downstream and upstream, distributing chunks of concrete on the slopes, and covering the blocks with dirt. Club member Steve Lindley, who is overseeing the riprap work as well as the golf course upgrade for the club, said that the plastic sheeting is porous and biodegradable and that club plans to seed the dirt with grass to keep it from washing away and eventually to plant it with native vegetation such as chili pequin.
