Buffalo Bayou Doesn’t Like Sidewalks, It Seems
Buffalo Bayou Park Was Supposed to Be More Stable

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 (and updated with later photos).

Fighting For Our Public Forests on Buffalo Bayou
On the Radio
Forests Work for Us
Oct. 28, 2015
Listen to Susan Chadwick of Save Buffalo Bayou and Landrum Wise of Save Our Forest talk about community campaigns to protect public forest along some twelve miles of Buffalo Bayou in Houston.
They spoke with Pat Greer and H.C. Clark on Eco-Ology on KPFT 90.1 Tuesday, Oct. 27, 2015, about efforts to keep the City of Houston and the Harris County Flood Control District from destroying woodlands on Buffalo Bayou in Memorial Park in the center of Houston and in Terry Hershey Park in far west Houston.
In addition to their great social value and benefit to our health, well-being, and quality of life, the trees and vegetation that grow naturally along the bayou perform vital ecological services and are a key part of the bayou’s living system. Known as riparian zones or buffers, these specially adapted trees and plants cleanse and filter pollutants from the water. They protect the banks from erosion, absorb and slow storm water runoff and provide natural flood detention. They shade us and cool the stream, and provide wildlife habitat.
Legally Required to Conserve Harris County Forests
The Harris County Flood Control District, according to its 1937 charter, is charged by state law with conserving forests in the county. (See page six.) But for decades the district has been razing forests to build storm water detention basins on our bayous, creeks, tributaries, and elsewhere, and to re-engineer channels and banks. Detention basins are used to hold or slow temporarily surface runoff or high flows in a stream during storms.
The flood control district’s project on Buffalo Bayou in Memorial Park, known as the Memorial Park Demonstration Project, would raze some 80 percent of the trees and vegetation along more than 1.25 miles of the bayou and its tributaries in Memorial Park and the Hogg Bird Sanctuary. The Army Corps of Engineers, which enforces the federal Clean Water Act, is currently considering whether to issue a permit for the controversial $6 million project, which is described by flood control as an “erosion control” and “bank stabilization” project. The project violates Best Management Practices for riparian areas. Virtually every federal and state resource agency has policies and regulations protecting riparian zones, which perform essentially the same function as federally-protected wetlands.
Recent Success for Save Our Forest
The City of Houston recently withdrew a project to cut down the majority of trees and understory on some 42 acres of public forest and excavate up to six large detention basins on the south bank of Buffalo Bayou in Terry Hershey Park between Beltway 8 and Wilcrest Drive. The Capital Improvement Project was to have cost the taxpayers between $3.5 and $8.5 million.
However, the flood control district appears to be continuing with its widely-opposed “Charting Buffalo” study that proposes as many as 24 storm water detention basins along some 10.7 miles of both banks of Buffalo Bayou in the forests of Terry Hershey Park between Beltway 8 and Highway 6 at Barker and Addicks dams. On Nov. 12, 2013, despite public opposition, Harris County Commissioners Court approved flood control’s request for $250,000 for a vegetation and topography survey in the park.
The headwaters of Buffalo Bayou are on the Katy Prairie west of Houston, and the 18,000-year-old “mother bayou,” fed by numerous tributaries, flows for some 53 miles east through the city and the ship channel into Galveston Bay. Buffalo Bayou, unlike major bayous like White Oak and Brays, which join Buffalo Bayou just west and east of downtown, has never been covered with concrete, though parts of it have been channelized.
Listen to the radio broadcast.

This 10.7-mile stretch of the bayou downstream from Barker and Addicks dams was straightened and channelized by the Army Corps of Engineers in the 1950s to speed storm waters.

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.
Let’s work with nature, not against it.
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.

Float In The Air Down Buffalo Bayou With Houston Photographer Jim Olive
October 17, 2015
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
Once-a-Boat-Launch at Woodway to Re-Open by Mid-December
Meanwhile Buffalo Bayou Busy Replanting, Beautifying
Sept. 5, 2015
A contractor has been found at last to take down the heavy-duty chain-link construction fencing, put up some railing, spread some gravel and sod, and restore the informational sign in that western part of Memorial Park that was once a popular boat launch and is now referred to by public officials as a drainage outfall.

Closed to the public for more than two years, including more than a year after the $1.36 million taxpayer-funded solar-irrigated “erosion control” project was completed, the ugly, massively enlarged outfall draining Post Oak Road is still officially a Texas Parks and Wildlife Paddling Trail boat launch. Previously it was also a forested area with a nature trail.
But officials with the Uptown Tax Increment Reinvestment Zone (TIRZ) 16 now seem genuinely eager to do “what we can to get it open to the public,” said John Breeding, administrator, at the Uptown board meeting in a Galleria high-rise last Wednesday, Aug. 26.
The board voted without discussion to award a contract for $219,272.10 to Jerdon Enterprise, LP, which was the sole bidder for the long-delayed project. With “add-ons” the cost could go to $335,615.10. That seems like a lot of public money for taking down some chain-link fencing, putting up some standard railing, laying down some loose gravel, etc. But apparently no one else wanted to do it.
Work on the Outfall Phase II is now scheduled to begin this month and be completed by December 15, 2015.
And if you’re confused about why a TIRZ and not the parks department or the city council would be making these decisions, well, it is confusing. But the TIRZ has control of the money.
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.

Crazy Widespread Disappearance of Wetlands around Houston
Wetlands in Buffalo Bayou Threatened Too
Aug. 3, 2015
The Army Corps of Engineers is not keeping track of whether developers are replacing tens of thousands of acres of wetlands lost to development in the Houston region as required by law.
Wetlands, according to the Environmental Protection Agency, “are part of the foundation of our nation’s water resources and are vital to the health of waterways and communities that are downstream. Wetlands feed downstream waters, trap floodwaters, recharge groundwater supplies, remove pollution, and provide fish and wildlife habitat.”
Under the federal Clean Water Act, the Corps of Engineers is charged with protecting our wetlands.
A study by the Houston Advanced Research Center (HARC), reported by the Houston Chronicle Friday, July 31, 2015, found that “more than 38,000 acres of wetlands vanished in greater Houston over the past two decades despite a federal policy that ‘no net loss’ can be caused by encroaching development.”

While We Wait
The Flood Control District’s Failing “Natural Channel Design” Projects
July 11, 2015
Well, the comments are in to the Army Corps of Engineers. The comment period that ended June 5 was not extended. So now we wait to find out what the Corps will do next about a permit for the Harris County Flood Control District’s controversial $6 million Memorial Park Demonstration Project. The flood control district wants to destroy one of the last natural stretches of Buffalo Bayou as it flows past Memorial Park in the middle of the city so that engineers can “build it better,” thus demonstrating exactly the wrong thing to do for erosion control and bank stabilization on the bayou.
It’s the wrong thing to do because the specially adapted trees and plants on the bayou (known as the riparian zone) protect the land from erosion, slow storm water and runoff, filter pollution and bacteria (and trash) from the water, provide shade and habitat, among many other vital functions. Razing the riparian buffer, as this project would do, digging up and running heavy equipment over the banks and bayou bottom are all contrary to Best Management Practices and the policies of virtually every federal and state agency charged with protecting the health of our waters, our wildlife habitat, and our soil.
What Are the Options?
So what are the Corps’ options?

Permeable Paving Can Help Save Us and Our Bayous
Impervious Surface Is A Major Cause of Flooding in Houston
June 17, 2015
Yes, porous paving does work in Houston. We need to use more of this, on our hot, sunbaked parking lots, on our sidewalks, driveways, patios, and more. (It’s cooler too!)
Storm water runoff is a major problem for our bayous (especially those that have had protective trees and plants stripped from their banks). And impervious surface is the major cause of flooding and contributes to water pollution too. Instead of soaking into the ground (or being deflected by trees and leaves), filtering naturally and slowly through the soil and being cleansed of pollutants, storm water runoff gathers quickly, racing through toxic streets and highways, into drainage systems and pouring all at once into our bayous and creeks.
Here is an interesting and timely article in the Houston Chronicle by the founder of Houston-based TrueGrid, a permeable paving company that even creates permeable grass parking lots.
(Note to Houston park and street planners: we don’t need to have ugly, hot impermeable concrete or asphalt sidewalks to accommodate wheelchairs and runners. TrueGrid makes ADA compliant, permeable sidewalks.)
There is, in fact, also a permeable asphalt, recommended by the Environmental Protection Agency (EPA).
But here’s another interesting fact: in a typical urban residential area, rooftops account for 30-40 percent of the total impervious area. What can you do about that? Individuals can do a lot!
The Houston Arboretum has programs about how to build rain barrels and rain gardens. And here is an EPA slideshow about the importance of rain gardens and how to build them.
As the EPA says, “Slow it down, spread it out, soak it in.”
We don’t need to keep flooding and destroying our bayous, making them into bigger, uglier drainage ditches.
