Environmentalists Respond to Draft Coastal Protection Plan

Corps of Engineers Holding Public Meetings and Soliciting Comments


Dec. 13, 2018

[Updated Dec. 31, 2018, with the comment from the Houston Sierra Club.]

[Update Jan. 7, 2019: The Corps of Engineers has extended the comment period until Feb. 8, 2019.]

Climate change is causing the seas to rise and storms to become stronger, more frequent, and more destructive. In order to protect the industry and people of the Texas coast, the State of Texas General Land Office, together with the Galveston District of the US Army Corps of Engineers, is preparing a Texas Coastal Protection Plan.

The $20 million planning process began in 2015 and is expected to be completed by 2021. Upon completion a plan will be presented to Congress for authorization and funding, expected to be in the billions of dollars.

A significant part of the plan, which incorporates both large-scale engineered infrastructure and ecosystem restoration, focuses on the potential for a big storm to send a surge of seawater through Galveston Bay and up Buffalo Bayou into the Port of Houston, inundating the chemical plants and refineries and neighborhoods there along with downtown Houston, as well as houses, businesses, and highways on the coast.

In October the Corps released a draft feasibility study for the plan along with an environmental impact statement for the draft study. Since then they have been holding public meetings about it up and down the coast. The next meeting is Saturday, Dec. 15, in Crystal Beach at Crenshaw Elementary and Middle School, 416 State Highway 87, from 1 to 4 p.m. The next and final meeting is Tuesday, Dec. 18, in Seabrook, at the Bay Area Community Center, 5002 E. Nasa Parkway. The meeting begins at 5:30 p.m.

You can read the documents and find out more about the process and the public meetings here.

On Tuesday, Dec. 11, 2018, a group of regional and national environmental and conservation organizations, including Save Buffalo Bayou, released their response to the draft study and associated environmental impact statement.

One of the primary concerns was that “the information provided in the Feasibility Report and Environmental Impact Statement is insufficient to enable thorough and informed comments.”

The advocacy group response noted that there was no clear indication of where the various structures will be placed and few details on the overall impacts.

The organizations, led by Bayou City Waterkeeper, reiterated their preference for “non-structural solutions such as preservation and enhancement of prairies, riparian areas, barrier islands, and wetlands; buyouts/strategic withdrawal from areas that cannot be adequately protected, and appropriate land-use regulation to implement those concepts.”

They called for greater private sector responsibility for protecting private industry and keeping people out of harm’s way and for regulations preventing development in floodways and floodplains.

They also called for the preservation and restoration of riparian areas, green space, and barrier islands to increase stormwater storage capacity and reduce damage from flooding. “Our bayous, given sufficient floodplain, are our natural storm drains and detention systems. Preserving these areas also provides the important secondary benefit of recreational green space.”

Structural approaches, such as building dams, dikes, and levees, work against nature, encourage development in flood-prone areas, and should only be used where non-structural or nature-based methods are not feasible, they said.

You can read the full statement from the conservation groups here. Read the comment from the Houston Sierra Club here.

More information is available about the coastal protection plan and process through this notice in the Federal Register.

Comments on the draft plan must be postmarked by February 8, 2019. You may submit comments by email to CoastalTexas@usace.army.mil or by mailing to this address:

Giant Turtles and Other Bayou Creatures

Not So Secret Alligator Snapping Turtles


Dec. 12, 2018

So recently the Chronicle blew the secret that there are giant alligator snapping turtles in Buffalo Bayou.

But apparently it wasn’t much of a secret. Turns out that lots of people already knew about alligator snappers in the bayou and elsewhere. We posted the article on our Facebook page, and we were bombarded with stories and photos of close encounters with the big snappers over the years—as near as back yard ravines.

Last year volunteers with Save Buffalo Bayou participated in this long-term project sponsored by the Turtle Survival Alliance to tag and track the massive turtles, the operation described by the Chronicle’s Molly Glentzer. The turtles, the largest freshwater turtles in the world, are designated a threatened species by the State of Texas, which means it is against the law to capture, trap, take, or kill them, or even think about doing that. They happen to be an ingredient in classic New Orleans-style turtle soup and therefore subject to poaching, which continues in the state, even though these days alligator snappers for cooking are farm-raised. We were asked to keep quiet about the turtles until the turtle scientists had a better idea of how they were doing here. Apparently they are doing pretty well.

Explaining How Streams Work to Anxious People

A lot of people flooded on Buffalo Bayou. They are hurting. The impulse is to want to strip, dredge, deepen, straighten and widen our bayous. We are doing our best to explain why this doesn’t work and what will work instead. We continue to fight for sensible, cost-effective nature-based solutions to flooding across the region. It’s what the rest of the world is doing.

Modernizing Maintenance and Flood Management Practices

In the past year our nonprofit has helped improve outdated woody debris removal practices in our bayous. The modern way is to leave some large fallen trees against the banks for sediment control and protection against erosion and flooding. Contractors with Harris County Flood Control were taking all the trees, even cutting down live trees. As a result of our report, a subcontractor was removed.

Not Flooding Your Neighbor: Explaining Legal Rights and Responsibilities on the Bayou

The laws governing what a property owner can and can’t do on our public streams can be confusing. We published an in-depth report explaining all that. Big reveal: the property line is not where you think. We also describe why the bayou banks collapse, how they naturally rebuild, and offer insight into Best Management Practices on the bayou.

Helpful Links and Information

We provide the best collection of recommended books and articles on nature, rivers, and flooding, as well as useful links to flood gauges, floodplain maps, rainfall data, and more. And don’t overlook our Calendar of Events.

Nature: Not Just A Pretty Face

Environmentalism is based on science, not sentiment. We are constantly explaining why it is practical and necessary to understand how nature works, especially in regard to drainage and flooding. But we do love the river, the trees, and the beavers and birds. We regularly post photos and videos of our Buffalo Bayou that most people don’t get a chance to see.

And don’t forget our geology classes on the bayou led by Save Buffalo Bayou board member and consulting geologist Tom Helm. Tom is currently featured in a four-part series on Buffalo Bayou reported by KHOU’s Channel 11’s Brandi Smith.

A Broad Reach

The posts and photos on our website and Facebook Page reach thousands of people. We have more than 7,700 followers on Facebook as well as a mailing list of over a thousand politicians and civic leaders, agency officials, media representatives, and interested people pro and con. We also publish editorials in newspapers—daring to say what is controversial—and have been frequently featured in news reports.

The Future: Stopping Stormwater Before It Floods Our Streams and Neighborhoods

We all have a lot of work to do to save our city from increasing storms and flooding. Help us remain an important part of the conversation about the best way to do that. Flooding begins on the land. Imagine how beautiful and livable Houston could be with more parks, trees, gardens, and green space to help slow and absorb rain runoff.

Commissioners Court Oks Study for Bypasses on Buffalo Bayou Meanders

$350,000 Contract Includes Study of Bridges

Nov. 21, 2018

Harris County Commissioners’ Court has approved a $350,000 contract to study a controversial proposal for installing large concrete culverts through meanders on Buffalo Bayou.

The contract was awarded at a commissioners’ court meeting Nov. 13 to Texas-based engineering firm Huitt-Zollars. It also calls for studying the “hydraulic performance of bridge crossings” on the bayou as well as the “high-flow bypasses” of meanders.

The contract focuses on 33 bridges and 4 pipeline crossings on Buffalo Bayou between Highway 6 in far west Houston and Congress Street downtown. It identifies 13 potential meander bypass locations between Beltway 8 and Shepherd Drive. (pp. 11 and 12)

The meander bypass plan is based on a misunderstanding of the causes of flooding upstream and the beneficial function of meanders in streams. The idea was proposed by neighborhood activists living above Beltway 8 who blame the meanders of the bayou below the beltway for exacerbating flooding of their homes in low-lying floodplains adjacent to a six-mile-long stretch of the bayou that was straightened in the Fifties. That stretch of the bayou is now Terry Hershey Park, owned by the Harris County Flood Control District.

Meanders Not the Cause of Flooding Upstream

A study commissioned by Save Buffalo Bayou found that the bypass plan is likely unfeasible and could increase flooding and erosion of property downstream.  Save Buffalo Bayou is opposed to meander bypasses, which would be highly damaging, counterproductive, and a waste of public funds.

“Preserving old stands of trees, natural swales, wetlands, oxbows, vegetated riparian areas, and meanders; building small weirs, sediment structures, wet gardens, and setback levees; lengthening streams, and accepting large woody debris in the channel are useful techniques. Using these practices to work with the natural motion of the river is more effective – and less expensive – in reducing flood damage and helping us realize benefits from the water.”

Buffalo Bayou Update With Egrets, Hawks, and a Beaver

Floating Down the Bayou Into the Rising Sun


Nov. 20, 2018

It was just after sunrise on a beautiful fall day. Save Buffalo Bayou advisory board member Janice Van Dyke Walden had suggested a paddle down the bayou. We slid her wooden canoe into the water at the Woodway boat launch in Memorial Park and cast ourselves into the current.

The water was high and the flow fairly fast, about 700 cubic feet per second, strong enough to keep us moving without doing much except dip our paddles in occasionally. Janice did most of that.

The opaque brown water was roiling, disturbed by mysterious conflicts below. The fin and scaly back of a huge creature suddenly broke the surface—an alligator gar, one of the largest freshwater fishes in North America, and maybe one of the oldest, having been around for over a hundred million years.

Our route passed by the Houston Arboretum, Memorial Park, and the Hogg Bird Sanctuary. On the right bank there were private residences and the long edge of the golf course belonging to the River Oaks Country Club. We floated all the way past Shepherd (Buffalo Bayou is tidal to about 440 yards upstream of the Shepherd Bridge) into Buffalo Bayou Park, passing by numerous new and failed private erosion control projects. The best erosion control is not to landscape, water, or disturb the ground above or on the bank, to leave the trees and vegetation in place, leave fallen trees against the bank as protection against the flow and reinforcement of the bank, and let slumped material and vegetation naturally regrow. The bayou will take care of itself. And it will also seek out its historic path, which is one reason why they are having so much trouble with collapsing banks in Buffalo Bayou Park downstream, stripped and straightened in the Fifties and recently altered by Harris County Flood Control. (See also this slideshow of the historic meanders in Buffalo Bayou Park by geologist Tom Helm.)

We were pleased to see that some large trees had been left parallel to the bank with their roots towards the current. This is the science-based practice that floodplain managers recommend. We were critical of contractors hired by the Harris County Flood Control District to remove debris in the channel after Harvey. Paid by the pound, they were cutting down live trees and pulling up all the large wood. Large woody debris on the banks is essential for collecting and controlling sediment, protecting against erosion, and rebuilding the banks after floods.

Harvey made big changes in the bayou. Among other things, a small stream that drains the eastern edge of Memorial Park had shifted and cut through the sandy bank of what we call the middle meander. Further downstream another small tributary flowing through the Hogg Bird Sanctuary had likewise shifted slightly upstream and now cuts through a narrow spit of land that was clearly going to go some day. The former mouth of the stream below a high bluff in the public park had been blocked with sediment.

Watch this nine-minute video of our early morning float down Buffalo Bayou.

Fall Photographing with Jim Olive, a Butterfly, and a Coral Snake

Monarch Discovers Daisies on That Bend in the Bayou. Big Coral Snake Slithers By

Nov. 17, 2018

We were a little delayed for a fall photo of that Bend in the River. We have been documenting this particular place on Buffalo Bayou through the seasons for more than four years. Photographer Jim Olive has obligations elsewhere these days, so we had to go with the day he could be here and the early morning weather on that day.

It was overcast and the flow was a high, a little under 2,000 cubic feet per second (cfs). It had been raining. Base flow in the bayou–normal flow when it’s not raining–is about 150-200 cfs.

But we waited and waited for the right moment, which is what a professional photographer does. We were standing on that same high bank in Memorial Park in the middle of Houston looking at the bayou flowing downstream with River Oaks Country Club property on the opposite bank. It was the same location, but as you can see if you look at Jim’s series of photos, it has changed through the years. Nature is not static.

Jim patiently shifted position and cameras and lenses. In the meantime, as usual, the photographer’s assistant wandered off, looking around, mainly for something edible to forage, and found some small puffball mushrooms growing on a rotting log. These little, round white mushrooms are variously described as “edible” or “choice.” The latter means delicious. “Edible” means they won’t kill you but they don’t necessarily taste good.

There were daisies growing on the high bank, and suddenly a big orange and black Monarch butterfly was fluttering there, feeding on the flowers on its way to Mexico. If you look closely, you can see where it had been in Jim’s photo.

As we were leaving we encountered the most beautiful coral snake on the path through the woods, right where we had seen a gigantic, sleeping king snake coiled up in the old, broken drainage pipes left over from Camp Logan, the World War I training camp and military hospital that occupied this land back then. This snake was “red and yellow, kill a fellow” and not “red and black, all right, Jack,” so definitely a coral snake. Turns out there are numerous variations of this ditty we learned as children to distinguish a highly venomous coral snake from the harmless milk snake. But a coral snake is not aggressive. And it can hardly bite. So not really dangerous at all unless you try to pick it up. This one was very large and shiny. Jim, an expert naturalist, thought maybe it had just shed its skin.

Here is a video of the coral snake.

As for the little puffballs, they were okay. Ordinary, really. Not as delicious as the honey mushrooms or oyster mushrooms one can find growing in the park and along the bayou. The photographer’s assistant made a mushroom omelette.

How Katy Prairie Landowners Could Help Houston Fight Flooding

A Conversation with Jim Blackburn

Blackburn is an environmental lawyer, founder of the Bayou City Initiative, and co-director of the  Severe Storm Prediction, Education and Evacuation from Disasters Center (SSPEED) at Rice University in Houston

Nov. 13, 2018

Q: How could preserving the Katy Prairie help minimize flooding?

A: Preserving the Katy Prairie alone can be useful and, with management, even private lands that are in cattle production can be useful. Mainly, it is about getting roots to penetrate the soil and water following the roots down into the ground. If you combine that will a small levee like what is in rice fields, you can perhaps pond another foot of water on the flat land. Together, the potential to store water is substantial.

Q: It’s been said that the Katy Prairie acts like a natural sponge. How does this work?

A: The roots of prairie grasses penetrate and break the soil, and in doing so, they create natural pathways. There is space around the root, and the water naturally penetrates. Those roots go down five or six feet. With roots in the soil, a very impermeable clay soil can become permeable.

KPFT Radio Accidentally Revives Dead Bayou Project

Five-Year-Old Interview About Memorial Park Demonstration Project Causes Confusion

Nov. 12, 2018


Well, we were confused too and a little upset as we listened to Evelyn Merz of the Houston Sierra Club being interviewed this afternoon on KPFT by Mike Honig of Thinkwing Radio about the Memorial Park Demonstration Project. That project would have stripped, dredged, and rerouted over a mile of Buffalo Bayou flowing past Memorial Park in the middle of Houston. The stretch is a historic nature area, one of the last remaining publicly-accessible forested stretches of the bayou in the city.

But the more we listened, the odder is seemed. Above all because the project is dead. Save Buffalo Bayou was founded over four years ago to stop this pointless project, which was promoted by Kevin Shanley of SWA Group, the landscape architecture firm responsible for Buffalo Bayou Park. (See the problems here.) The firm also happened to be on retainer with the Harris County Flood Control District, which became the official sponsor of the project, believing it had community support. Shanley was then the president of the Bayou Preservation Association. And for a time the project manager for the engineering firm hired to do the project was also on the board of the association.

In any case, it was a terrible, unpopular idea that served no good purpose and wasn’t going to work anyway. Based on a faulty analysis of bank collapse on the bayou, the project cost had increased from $6 million to $12 million. And after Harvey in August 2017, Flood Control District Director Russ Poppe, who inherited the project from his predecessor, publicly declared at a Bayou Preservation Association symposium that the project would not be going forward.

It turned out that the radio interview with Merz was five years old, and someone at KPFT had pulled it off the shelf to fill air time.

Merz, a member of Save Buffalo Bayou’s advisory board, was outside doing chores during the broadcast and just as surprised as everyone else to hear about it. She is also chair of the conservation committees of the Lone Star (Texas state) Chapter of the Sierra Club as well as the Houston Regional Group of the Sierra Club,

Station manager Don Freeman was apologetic, explaining the station operates “on a shoestring.” We urge everyone to support the nonprofit KPFT, a valuable public resource.

Birds of the Bayou

Report from Buffalo Bayou beat correspondent Janice Van Dyke Walden

Nov. 11, 2018

I had the great pleasure this weekend to take wildlife photographer Greg Lavaty canoeing down Buffalo Bayou to photograph birds. In the three hours of an overcast morning in the section of Memorial Park/River Oaks, Greg heard or spotted 33 bird species (full list below, along with some of his photos). Many thanks to Gary Studwell who helped crew so Greg could have a stable experience in fast water. It is truly wonderful that we have this wild corridor in the middle of our nation’s fourth largest city. Let’s keep it wild.
