Let’s Work With Nature, Not Against It
What’s the right way to protect Buffalo Bayou?
March 18, 2015 Updated: March 18, 2015 11:20am
Is the traditional vision of local and urban flood control agencies in conflict with federal and state agencies charged with protecting the health of our waterways?
Let me explain how I came to ask myself this question about mission conflict.
I grew up on Buffalo Bayou in Houston, and since early last spring I have been involved with a campaign to stop a flood control project that would destroy and then attempt to rebuild a healthy and relatively untouched riparian forest corridor running through the center of our city. It’s pretty rare to have a stretch of fairly wild river running through the middle of such a large city. The late great conservationist Army Emmott described our Buffalo Bayou as a ribbon of life running through the concrete. And that’s what it is: a living thing, a diverse and dynamic ecosystem that shows us the wondrous process of nature.
We are even more fortunate that in the words of the great river scientist Mathias Kondolf of Berkeley, this enchanting river has “room to move.” Here, in the middle of the city, we have space to “let the river be a river” — to let its banks change and its forest garden grow, as they would naturally. Dr. Kondolf traveled through this reach of the bayou in November, a reach that has never been channelized. The nearly 1.5-mile stretch targeted for destruction flows between the riparian forest and great cliffs of a public park (Memorial Park) and the forested terraces and high banks of a private golf course.

Room for the River: What the River Scientist Had to Say
Nov. 25, 2014
Updated Saturday, Nov. 29, 2014, with a link to the video of the lecture by Mathias Kondolf.
More than 100 people gathered last Friday evening to hear Mathias Kondolf speak about rivers, river restoration, and the state of Buffalo Bayou at the Assembly Hall of St. Theresa Memorial Park Catholic Church.
Kondolf is a professor at the University of California at Berkeley, a world-renowned river scientist, and a leading critic of the destructive and often-failing methods proposed for a $6 million “erosion control” and “bank stabilization” project on Buffalo Bayou. He spoke for nearly two hours to a crowd that included people on all sides of a controversial project to bulldoze the riparian forest and dredge and channelize nearly 1.5 miles of one of the last natural stretches of the bayou in the city.
The project, known as the Memorial Park Demonstration Project, was conceived by the Bayou Preservation Association, which actively promotes the plan. The Army Corps of Engineers is considering whether to issue a permit to the Harris County Flood Control District for the project.
Riparian forest or buffer, also called a riparian zone, consists of specially adapted trees and plants along the edge of a waterway. Among the many important functions of riparian zones are protecting the land from erosion, filtering pollution, cleansing the water, slowing flood water, and providing wildlife and human habitat.
Kondolf had spent hours inspecting the bayou in the rain earlier in the day. The project area is bounded entirely on the south by the River Oaks Country Club golf course, which is currently being renovated. The north bank of the project is our public Memorial Park, along with the Hogg Bird Sanctuary and some private property. Taxpayers are contributing $4 million to this project.

An Outstanding Job by Environment Reporter Dave Fehling on Buffalo Bayou and the Importance of Riparian Forest
Dave Fehling did an outstanding job of reporting for the Houston Matters radio show on the Buffalo Bayou bulldozing project that aired last Wednesday, Oct. 8, 2014. (Segment starts at 18:35.) Fehling is Houston Public Media’s State Impact reporter for Energy and the Environment.
Most importantly Fehling recognized and addressed the main issue completely ignored by the project promoters: the importance of riparian forest, which is basically wetlands necessary for cleansing our waters, controlling erosion and flooding, and providing wildlife habitat. (Yes, in addition to clean water, we need hawks and dragonflies and alligator snapping turtles to survive. We are all linked in the chain of nature.)
This project would destroy most of the perfectly healthy riparian buffer along almost 1.5 miles of the last natural stretch of our 18,000 year-old Buffalo Bayou as it flows between Memorial Park and the Hogg Bird Sanctuary on the north and the golf course of the River Oaks Country Club on the south. (The club happens to be in the process of rebuilding its entire golf course.)
Two important points that we’d like to clarify and that are causing confusion in the public mind:
- This is not a disagreement between conservationists. This is a battle between conservationists on the one side and developers and profiteers on the other. The influential Bayou Preservation Association, which was instrumental in creating this project and which continues to be its strongest advocate, is no longer a preservation group. The president of the BPA works for the Energy Corridor District, the development agency for the Katy Prairie in West Houston, one of the fastest growing areas in Houston and source of Buffalo Bayou. The BPA board is heavy with representatives of major engineering, construction, and landscape design companies. On the board is a representative of KBR, the engineering contractor for this bayou project. Representatives of the flood control district sit on the advisory board.
- This area is not suffering from severe erosion. See below.

Update on Our Campaign to Save the Last Natural Stretch of Buffalo Bayou in Houston
Oct. 5, 2014
Where are we now and what should you do?
The Harris County Flood Control District has applied for a permit to bulldoze most of the riparian forest and vegetation along both banks of more a mile of the last remaining stretch of natural Buffalo Bayou in the city. This is our bayou as it passes by Memorial Park. Also targeted are the tributary and high bluffs of the Hogg Bird Sanctuary, as well as other ancient cliffs and prehistoric sandstone used in the past as water crossings by buffalo and people. The project would excavate, fill, grade, and artificially rebuild the banks; dredge, deepen, and reroute the bayou channel, damming tributaries. Hundreds of trees will be cut down, many of them riparian species too small or too young to be counted by the district’s inappropriate tree survey. The shading tree canopy will be removed (project proponents claim there is no tree canopy!); the water temperature increased. The soil, packed with protective, binding roots small and large, will be dug up, tossed around, and compacted by heavy equipment. Wetlands and lovely sandy beaches will be obliterated along with the colonizing and stabilizing plants that have taken root there, a crucial stage of the natural process of building the riparian buffer so important to water quality, flood and erosion control.
All of this and more violates best management practices for riparian zones. It will destroy the bayou’s ecosystem. And this is a project developed and promoted by the Bayou Preservation Association, supported by the Memorial Park Conservancy.
Timelines Are Difficult to Predict — Updated Oct. 30, 2014
The Harris County Flood Control District has responded to the public comments sent to the Army Corps of Engineers during the public comment period, which ended June 30. The district has posted its responses on its website, and you can read them here. (Caution: big pdf.)

Memorial Park, the Master Plan, and Our Wild Buffalo Bayou
Sept. 15, 2014
Proposals for a new master plan for Memorial Park will be presented at a public meeting on Wednesday, Sept. 17, from 6 to 8 p.m. at the Eldorado Ballroom, 2310 Elgin Street. Anyone concerned about the future of our great Memorial Park and Buffalo Bayou as it flows past the park will want to attend this meeting, one of four “update” meetings scheduled about the plan over the next several months.
The prominent national landscape architecture firm of Nelson Byrd Woltz is leading development of the plan. Thomas Woltz, principal of the firm, and his team will share results of their research and analysis, as well as initial design concepts at the Wednesday meeting co-hosted by Houston City Council Members Dwight Boykins and Robert Gallegos.
Do Nothing to Our Wild Bayou is the Best Policy
The last master plan for Memorial Park in 2004 recommended that nothing be done to disturb the natural environment of Buffalo Bayou. After extensive analysis by a team of fluvial geomorphologists and hydraulic engineers, the plan wisely concluded that “the recommended course of action for the Bayou is simply to leave it alone and consider it a symbol of dynamic natural process. The Bayou can serve as a valuable environmental education tool that depicts the change inherent in nature.”
It is not yet known, to us at least, what recommendations the new master plan will make about our treasured last stretch of wild bayou in Houston. However, contradicting the clear conclusions of the 2004 master plan, the Memorial Park Conservancy officially and actively supports the Bayou Preservation Association‘s bizarre project to bulldoze the bayou’s riparian forest, level and grade the banks and cliffs, dredge, channelize, and reroute the bayou. This would forever destroy a valuable and historic natural resource in our great public park, an amazing oasis of riverine wilderness in the middle of the city.

Reminder: Meeting With City Council Members Representing Buffalo Bayou
July 29, 2014
Public Meeting with Council Members Pennington and Cohen
It’s about Shepherd Drive, but go and ask why they support the project to destroy Buffalo Bayou.
Plus The Top Ten Reasons They Give for The Awful Project and The Correct Answers
Don’t forget the public meeting tonight (Wednesday, July 30, 2014) with City Council Members Oliver Pennington (District G) and Ellen Cohen (District C), who represent the wild banks of Buffalo Bayou to be bulldozed by the misguided project known as the Memorial Park Demonstration Project. Even the natives and the early settlers (including mill owners) knew better than to cut down the riparian forest on Buffalo Bayou, recognizing its importance for naturally controlling erosion of the banks, slowing storm waters, filtering pollution and bacteria, trapping sediment, and providing wildlife habitat.

Cohen represents Memorial Park, which belongs to all of us. And Pennington, who is running for mayor, represents the south bank of the project, owned by the River Oaks Country Club, stewards of the riparian forest for which it is named since 1923. Pennington also represents that little-known section of Memorial Park just west of 610, now known as the Bayou Woodlands, formerly the Archery Range. There, just off Woodway, a failing “erosion control” project is spewing mud and silt into the bayou. Previously this was a lovely forested ravine with a nature trail. The TIRZ 16, encompassing the Galleria area, now including Memorial Park, and a special kind of improvement district that gets to keep and spend tax money that would have gone into the city treasury, spent $1,147,934 on this particular drainage boondoggle designed by engineering firm AECOM, which also designed the failing “erosion control” project on the banks of the Houston Country Club.
So go and ask these city council members why they support the destruction of some of the last best, healthiest and most beautiful bayou we have in the city. The project would destroy nearly 1.5 miles of the bayou, including most of the forest on both banks, dredging up and rechanneling our lovely, shady stream, obliterating creeks and prehistoric bluffs too old even to contemplate, killing and driving away wildlife, trampling and removing habitat, and so much more that is wrong. The Army Corps of Engineers is considering whether to issue a permit for the project.
The meeting, held in conjunction with the city Public Works and Engineering Department, is from 6 to 7:30 p.m. at St. Anne’s Catholic Church (St. Basil’s Hall), 2140 Westheimer Road. The purpose is to review a paving and drainage project, set to begin in a few weeks, on Shepherd Drive from Westheimer to Buffalo Bayou. So it’s not exactly about the bayou project. But there will be a question and answer period.
Here are the Top Ten Reasons they give for destroying the bayou and how to answer.

The Bayou Banks We Could Lose
Once again, a flood-control project threatens Buffalo Bayou
By Susan Chadwick for the Houston Chronicle
July 25, 2014 | Updated: July 25, 2014 3:21pm
We have pulled the canoe up to a clean, white sandy beach on Buffalo Bayou in the middle of the city. It’s still early morning, and all along our slow paddle from the bridge at Woodway great white egrets and a great blue heron fly ahead of us, leading us to our destination: the prehistoric cliffs and forested banks that could soon be obliterated by the Harris County Flood Control District.
It’s a bizarre project, all the more incomprehensible in that the project is primarily promoted by the influential Bayou Preservation Association (BPA), founded in the 1960s to prevent the flood-control district from bulldozing the natural beauty of Buffalo Bayou.

A Moving Comment from Preservation Texas
July 6, 2014
The period is now closed for public comment to the Army Corps of Engineers on the application from the Harris County Flood Control District to bulldoze the wild banks of Buffalo Bayou in and around Memorial Park. The fight for the life of our beautiful southern bayou grows stronger. We must continue to raise awareness about this little known project, educate our friends and neighbors about the senseless destruction that is planned, and try to change the minds of our politicians and civic leaders. See What To Do Now.
The Army Corps received numerous comments opposing the project from experts in the field and ordinary citizens who cherish access to this unique treasure in the middle of our city. Among other things, the project violates state (pdf) and federal policy (pdf) protecting riparian buffer on our waterways.
Here is a particularly eloquent comment sent to the ACE from Preservation Texas:
June 30, 2014
Mr. Dwayne Johnson

U.S. Army Corps of Engineers
P.O. Box 1229

Re: SWG-2012-01007 (Memorial Park Demonstration Project)
Dear Mr. Johnson:
We write this letter to urge denial of the permit application referenced above.
Preservation Texas included the site of the Memorial Park Demonstration Project on our 2014 Texas’ Most Endangered Places list. The scope of the project far exceeds the limited erosion problem this particular stretch of Buffalo Bayou faces. The project should be narrowed to address only portions of the Bayou that are actively eroding and in a manner that does not destroy significant vegetation, rock outcroppings, potential archaeological sites and otherwise alters the slowly, naturally evolving course of the historic waterway by cutting and filling.
A recent 14-mile paddle down the Bayou reveals that most of the erosion in the project area has been caused by the removal of trees. Coupled with increased water volumes caused by overdevelopment of areas in the Bayou’s watershed, it becomes clear that the challenges of the Bayou extend beyond the waterway itself. A radical grading and replanting project does not address root causes.
Deadline Monday, June 30, for Comments Opposing the Bulldozing of Our Beautiful, Wild Buffalo Bayou
June 29, 2014
The deadline is Monday, June 30, for the Army Corps of Engineers to receive your comments opposing a permit for Harris County to destroy nearly 1.5 miles of our wild Buffalo Bayou in and around Memorial Park, including the Hogg Bird Sanctuary. The fight for the life of our proud, southern bayou will continue, and we will prevail with your help.
However, you must let the ACE as well as all our political representatives know that you oppose this bizarre, wasteful $6 million project. Here’s how to do that. In addition you can sign the MoveOn.org petition that will be sent to the proper authorities on Monday.
The pointless, destructive project that we oppose is being dishonestly promoted as a “restoration project aimed at reducing erosion and sedimentation and improving water quality, while providing for improved aquatic resource functions,” according to the permit application from the Harris County Flood Control District. (See page 13 of the permit application. Warning: big pdf file.)
Their project will do none of those things, and the plain proof is in their own permit application.
Our Buffalo Bayou Is Not in Need of Restoration
1. The first thing to know is that the bayou here is not in need of restoration. Buffalo Bayou as it flows between Memorial Park and the Hogg Bird Sanctuary on the north and the River Oaks Country Club on the south is some of our last natural bayou and riparian wilderness remaining to the people of Houston.
This, our most beautiful reach of the bayou, long preserved as part of our public park, is in better condition than any altered stretch of the bayou, and to know why it’s important to understand what a riparian forest buffer is. A riparian forest already does everything that they claim to be the purpose of this boondoggle: it controls erosion and sedimentation, improves water quality, filters pollution, slows storm waters, etc. Every single academic and professional paper you can find emphasizes the importance of protecting riparian buffer. No true river scientist advocates bulldozing riparian buffer.
- The condition of most of the riparian buffer on the banks of our Memorial Park is rated as near-perfect, a score of 4.5 out of 5, according to the county’s own permit application. See page 450 in the permit application.
- A magnificent, very old high bluff in the Hogg Bird Sanctuary, and the lovely tributary it overlooks, have perfect riparian buffer. (Pages 533 and 557).
- Even much of the south bank owned by the country club has near perfect riparian buffer.
- Overall the riparian forest in the entire project area has a near-perfect average score of 4.5, and there will be no significant improvement from this costly project. “The overall Riparian Buffer Variable is anticipated to stay at high sub-optimal (Score 4.5) level.” (Page 452.)
- The average score of our natural riparian forest in this area is significantly reduced by the eroding lawns of a few large, private homes on the north bank and the inclusion of edges of the manicured golf course on the south bank.
The riparian forest of our public park is functioning as it should. Why should we sacrifice our beautiful, naturally functioning bayou because private homeowners stripped the riparian buffer on their property to create lawns? Why should we taxpayers pay millions to restore private property while destroying our own public property?
When They Say Restoration, They Mean Destruction
2. What do they mean by “restoration?”
Since our bayou forest is fine, in order to “restore” it, they first have to destroy it.
They will do this by bringing heavy equipment into our park and cutting access roads to the bayou through the forest. (See Map 1.) They will use the bulldozers and backhoes to strip the trees and vegetation from eighty percent of the project area (not thirty percent as claimed by the Bayou Preservation Association), regardless of its condition and including in the scenic Hogg tributary. (See Map 2.) They will scrape up the riparian sand and soil in the banks, the ancient sandstone and red clay (our geologic history) and archeological remains, and cart it away somewhere. They will dig out and cut new channels in the bayou, lay down logs and other stuff, fill in parts of the bayou, which includes more than two dozen wetlands, deface and cover up the thousands-year-old high bluffs, bring the soil and sand back, grade the banks and create new slopes, cover the new banks with fiber mats and Bermuda grass, and plant some lilies and trees.
Map 1: The dotted red lines show the 14.35 acres of riparian forest to be scraped and bulldozed. According to the HCFCD, 80 percent of the vegetation in the targeted area will be removed. Note the areas to be cleared of trees extends into the interior of Memorial Park towards the maintenance facility. This is for access by heavy equipment to the bayou. Also note the land and forest to be lost by the River Oaks Country Club on the south, and the destruction of a scenic tributary and a magnificent high bluff in the Hogg Bird Sanctuary on the north.
Why Do They Need to Bulldoze the Forest In Order to Restore It?
3. Why don’t they just plant trees and shrubs, etc. on the few bank areas where the riparian buffer is poor? Much cheaper and less complicated. The Bayou Preservation Association, which bizarrely supports this destructive project, in a four-page position paper dated June 23, 2014, says that “the pattern of storm water releases … from the Addicks and Barker Reservoirs makes the re-vegetation approach untenable.”
But doesn’t this also apply to their purported plans to re-vegetate the 80 percent of the project length that they plan to strip and recreate? Or do they plan to leave their newly “restored” banks essentially bare and shadeless?
Erosion and Sedimentation Will Not Be Reduced, and Water Quality Will Not Be Improved.
4. The HCFCD permit application claims that this small natural riparian area contributes “approximately 359 tons per year of soil erosion.” (Page 447.) That sounds like a lot, but our analysts have put that into perspective. If you spread out that entire year’s worth of soil erosion on a football field between the twenty and forty yard lines, the sediment would be only nine inches high.
The vast majority of the sediment comes from further upstream. (See page 446.) Buffalo Bayou is twenty-six miles long from the Addicks and Barker dams in Katy to the Sabine Street bridge downtown. This short but significant project area in and around our Memorial Park is our best natural, functioning bayou. It contributes only an infinitesimal amount of sediment to the waterway. There is no evidence anywhere in the application permit, no scientific studies, no explanation of how or why excavating and filling in and rechanneling the bayou reduces erosion better than the natural system already in place.
Furthermore, removal of sediment from the water has no impact on the amount of bacteria in the water. This is according to the expert analysis of Dr. George Guillen, executive director of the Environmental Institute of Houston and an associate professor of biology and environmental science at UH-Clear Lake.
But don’t listen to us. Read the HCFCD’s application permit. Page 452: Water quality will not be improved.
Map 2: Areas of the natural banks of Buffalo Bayou to be excavated and filled. Yellow is excavate. Orange is fill.
This Project to Destroy Our Beautiful Buffalo is Nothing Other than the Same Old Flood Control Project to Make Buffalo Bayou a Bigger Drainage Ditch.
“The project purpose is … improvements to the dimension, pattern, and profile allowing the stream to convey storm water and sediment loads more efficiently.” Page 2 of the permit application.
This stealth flood control project is a joint venture between Harris County, the City of Houston, and the River Oaks Country Club. Each entity is contributing $2 million to the $6 million cost of the “demonstration” project, and the Houston city council voted last June to approve and fund it. This zombie channelization plan, a “holistic” variant of proposals long opposed by the Bayou Preservation Association, was largely conceived by the board of the BPA, who must be in need of work, do-nothing preservation being too passive and non-remunerative to somebody, and is actively promoted by the BPA and the Memorial Park Conservancy despite the huge of loss of trees and wildlife habitat, and damage to the bayou and our great public park.
A Misguided Project and Waste of Public Funds
July 19, 2014
Often the best project is to let the river fix itself. — Mathias Kondolf, “Meander Bends, Landscape Preferences, and River Restoration.” p. 51
Mathias Kondolf is one of the world’s leading river scientists. He recently wrote a letter to the Army Corps of Engineers recommending that the corps deny Harris County a permit to bulldoze the wild banks of Buffalo Bayou in and around Memorial Park.
The $6 million project would remove most of the riparian buffer from nearly 1.5 miles of some of the last remaining stretch of natural bayou in our city, demonstrating to landowners up and down the bayou and elsewhere the exact wrong thing to do. By far the most beautiful and healthiest stretch of the bayou, as it flows past Memorial Park and the Hogg Bird Sanctuary this shady, slow-moving wild bayou belongs to all of us. And amazingly, it is right here in the middle of our big city.
The project, promoted by the Bayou Preservation Association and officially a project of the Harris County Flood Control District, has no scientific or any other justification, says Kondolf. He points out that even the HCFCD says in its permit application that the stream is “recovering” (from something) and questions the county’s odd claim that razing the trees and vegetation, excavating and filling in the banks, and realigning the channel would “decrease the time needed for natural recovery.”
Kondolf points out that the existing riparian habitat is of “high quality,” that the erosion rate of the banks in the target area as estimated by the county is “not really problematic,” and notes that the construction project itself would likely dump three times more sediment into the waterway than this area does in a year.
Read Mathias Kondolf’s letter to the Army Corps of Engineers.
