Urban Riparian Symposium
The Challenges of Healthy Urban Streams
Jan. 14, 2017
There is still time to register for a February symposium in Houston on urban riparian areas — those special zones of trees and plants along stream banks so important for clean water, flood and erosion control, and wildlife.
The Texas Riparian Association has organized a three-day conference Feb. 15-17 largely directed at natural resource professionals but useful to anyone interested in the health of our urban bayous and creeks flowing into Galveston Bay.
Save Buffalo Bayou is a co-sponsor of the event, titled “Balancing the Challenges of Healthy Urban Streams,” to be held at Rice University’s BioScience Research Collaborative (BRC), 6500 Main Street. The registration deadline is Feb. 8. To register or find out more info, click here.
Save Buffalo Bayou’s Tom Helm, geologist, naturalist, and river guide, will be presenting Friday morning, Feb. 17, on the topic “Searching for the Original Meanders of Buffalo Bayou.”
Helm and Save Buffalo Bayou will also be offering float trips on Buffalo Bayou past Memorial Park and into Buffalo Bayou Park in the middle of Houston to symposium participants. The three-hour trips take place Friday afternoon from 1:30 p.m. to 4:30 p.m. and Saturday morning starting at 10 a.m. Cost is $50 per person. For more info or to reserve a place, contact Tom Helm.
Among other topics to be addressed: daylighting buried urban streams, the capacity of Houston’s urban forest to cleanse polluted stormwater, the economics of using natural drainage systems in development, how Austin protects riparian areas, incorporating the value of ecosystem services into regional policy decisions, managing large woody debris in urban streams, and more.
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.
Proposed Roads to Damage Katy Prairie Preserve
Urgent Notice of Public Meeting and Comment Deadline
May 1, 2016
Updated May 3, 2016
The Katy Prairie Conservancy has announced that the Harris County Engineering Department has corrected the email link for commenting on proposed changes to the Harris County Major Thoroughfare and Freeway Plan that will damage the Katy Prairie.
The correct email address is:
Update May 8, 2016
The comment period has been extended until May 13.
The Katy Prairie Conservancy has sent out an urgent notice of a Harris County plan to build new roads in and around the Katy Prairie Preserve. The preserve is a nonprofit land trust project to restore and protect historic wetland prairie in Waller and western Harris counties.
Buffalo Bayou originates in the Katy Prairie. Prairie wetlands, rapidly being destroyed and paved over by development, are vital for clean water and flooding mitigation, as are forested riparian zones along the banks of streams such as Buffalo Bayou and its tributaries.
When, Where, and How
The Harris County Engineering Department is holding a public meeting Monday, May 2, 2016, on proposed changes to the Major Thoroughfare and Freeway Plan (see particularly pages 25 through 29) that will “degrade the Katy Prairie Preserve System,” according to the conservancy.
The meeting takes place from 5:30 to7:00 pm at the Hockley Community Center, 28515 Old Washington Road, in Hockley, Texas.
The conservancy urges that if you cannot attend the meeting, please submit your comments in writing by May 13, 2016, via email to email@example.com or by mail to:
Harris County Engineering Department
10555 Northwest Freeway, Suite 120
Houston, Texas 77092
Attn: Fred Mathis, P.E.
The conservancy says that while Harris County is proposing to dispense with parts of the one-mile road grid through some of the preserves, the county also recommends constructing new roads in sensitive and/or inappropriate areas.
Here are some of the conservancy’s main objections:
- In general, the plan does not effectively take into consideration the importance of the Katy Prairie preserves in reducing flooding, improving water quality, providing wildlife habitat, and offering recreational opportunities for the residents of the Greater Houston area. Roads should go around the Katy Prairie preserves and not through them. Roads can move, nature cannot.
- KPC does not support the new proposed east-west road through the upper third of the Warren Ranch; it will cause fragmentation and impair ranch operations.
- KPC does not support the new proposed north-south road through the conservation easement lands owned by KPC’s conservation easement donors; this land provides sensitive habitat and flood protection as well as other environmental benefits. It should be protected.
- A number of the proposed new roads, if built, would be under water during flood events if the most recent flood event is any indication of where floodwaters go on the prairie.

Informative Articles in Response to Tax Day Flooding
A Roundup of Opinion on What Happened and Why
April 25, 2016
Houston neighborhoods shouldn’t be detention ponds
Commercial developers are dumping their runoff into our homes
By Bruce Nichols for the Houston Chronicle
April 19, 2016
Houston has a lot of great characteristics. It is open to new people, new ideas. It encourages entrepreneurs. Its energy-based economy is strong, despite the slowdown. But one big flaw is our failure to organize local government to protect homeowner investments, a big share of life savings for most of us.
The latest example of what this flaw leads to: Hundreds of homes flooded April 18. It was not a one-off event, a freak of Nature, as we have been assured. It will happen again, to more people, as more and more land is paved over without developers’ controlling their excess runoff.
Don’t blame Mother Nature for flooding. Blame City Council.
The disasters are predictable. Why aren’t we preventing them?
By Cynthia Hand Neely and Ed Browne, Residents Against Flooding, for the Houston Chronicle
April 19, 2016
Man-made, preventable flooding has surged dirty, sewage-ridden water through Houston living rooms three times now in seven years, yet city government fails to prevent these recurring emergencies.
Really? If losing homes, livelihoods, retirement savings, health and sanity (and at least one life) aren’t reasons enough to make emergency detention and drainage improvements, what in the world does it take?
Right now, too many real-estate developments do not detain storm water run-off from their new construction, and instead allow it to flow downstream into other neighborhoods, into people’s homes. This new development is responsible for unnecessary flooding of neighborhoods that previously weren’t flood plains, weren’t prone to flooding. That new development is also responsible for flood insurance rising 100 to 200 percent (before the Tax Day flood) in these non-flood plains.
City government is allowing this to happen. Developers use loopholes and grandfathering to avoid doing what the city’s laws require them to do. Is it ethical to allow a new office building to flood an entire neighborhood even if a loophole makes it legal?
Disaster by design: Houston can’t keep developing this way
We can’t stop growing. But to avoid flooding, we’ve got to be smarter about it.
By John S. Jacob for the Houston Chronicle
April 20, 2016
Let’s review the facts before this teachable moment fades away.
We live on a very flat coastal plain — much of it only a four-foot drop over a mile. And much of it with very clayey, slow-to-drain soils. We also live in the region of highest-intensity rainfall in the continental U.S. So it is going to flood. Mother Nature will continue to deliver floods no matter what we do. Don’t count her out.
Flooding does not occur uniformly across the region. There are floodplains, and areas near the floodplains. There are low areas and there are higher areas. We need to know where these are. Obviously! — and yet we don’t seem to know.
But humans have screwed things up royally.
Wrecked wetlands lead to flooding. Here’s what you can do.
By Jennifer Lorenz for the Houston Chronicle
April 20, 2016
For the past twenty years, we at Bayou Land Conservancy have watched, horrified, as the Houston region’s wetlands are scraped and filled in — directly resulting in increased flooding.
When wetlands are allowed to function, they’re the kidneys of the area’s watershed. Their special soil types are surrounded by particular wetland plants that help hold water in shallow depressions. They clean the water as they allow some of it to filter slowly into the ground, the rest to drain slowly into our bayous. That process is the foundation of our region’s ecology.
The rampant destruction of our forested and prairie wetlands is upsetting this balance, drastically reducing the land’s ability to absorb water. By allowing so many wetlands to be turned into subdivisions, we’re not just kicking them to the curb; we’re turning them into curbs. We need the ecological equivalent of dialysis.
How policy fills Houston living rooms with water
We know how to lessen flood damage. But will we take the steps?
By David Crossley for the Houston Chronicle
April 21, 2016
The flooding of April 18, 2016, was a profound experience for many reasons. The electrifying videos from drones, so quickly and easily available on Facebook, and hours of television enterprise brought us the clearest picture we’ve ever had of the immensity and the tragedy of flooding in Houston, and another reminder that all neighborhoods are not equal.
It was a spooky and historic picture; that was the most one-day rain in Houston’s history.
Extreme rain events like this are going to be more common as we slide further into climate change. Are we doing things to ease the slide or are we making it worse?
Greenspoint, poverty and flooding
Would low-income families be better or worse off if flood-prone apartments were razed?
By Susan Rogers for the Houston Chronicle
April 22, 2016
Floods, like any natural disaster, are great levelers. All of those affected suffer equally. It is in the wake of a great loss that the disparity emerges. For some, it can be easy to find the resources to rent a new apartment, to move, to turn on your utilities — or at least not extremely hard. For others, those financial challenges are overwhelming.
That division shows sharply in Greenspoint, where some of this week’s worst flooding occurred.
The mall, office towers, multi-family apartment complexes, and strip retail development are disconnected and isolated from each other both physically and demographically. Fundamentally there are two communities: one community that caters to the area’s office workers, and one community for those who call the area home. The stores and restaurants that line Greens Road and Greenspoint Drive, which cater to office workers, are closed during the evenings and on weekends, when the area’s residents would be more likely to shop.
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.
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.
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 .
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.
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.
Note: This opinion piece is adapted from a presentation delivered February 12, 2015, at Texas’ first Urban Riparian Symposium, sponsored by the Texas Water Resources Institute, the Texas Riparian Association, and the City of Austin.
Operation Save Buffalo Bayou: Banners, Signs Erected During Big Regatta Saturday, March 7
March 8, 2015
Defenders of Buffalo Bayou traipsed through clumps of wild chives and violets on the banks of the bayou Saturday, March 7, in order to hang colorful banners from bridges and trees and set out signs informing more than a thousand participants in the annual Buffalo Bayou Regatta about the grave threat to our wild bayou.
Operation Save Buffalo Bayou was a huge success as competitors paddling down the bayou waved and shouted “No bulldozers!” and “Leave it natural!” to members of the Buffalo Bayou defense team sitting on the banks in the project area.
Bayou defenders also handed out informational flyers at the end of the race in Sesquicentennial Park adjacent to the Wortham Center downtown and engaged participants and officials in conversation.
The regatta was organized by the Buffalo Bayou Partnership (BBP), a non-profit organization in charge of developing the $58 million Buffalo Bayou Park between Memorial Drive and Allen Parkway downstream of the project area. The partnership officially supports the $6 million plan to bulldoze one of the last natural stretches of the bayou as it flows past Memorial Park in the middle of Houston.
Sand on the Sidewalks
BBP President Anne Olson wrote a letter of support for the destruction project to the Army Corps of Engineers in June 2014 saying that the plan would “significantly prevent” the bayou from “depositing silt on Buffalo Bayou’s downtown parks and trails.” She also claimed that the project, known as the Memorial Park Demonstration Project, would demonstrate “a prototype that can be employed by bayou property owners who currently remedy their property erosion by all different types of inappropriate stabilization methods.”
In fact the amount of silt and sediment contributed by the historic nature area targeted for destruction by the Harris County Flood Control District is minimal. But the project itself would likely greatly increase the sediment flowing downstream as a result of dredging the bayou, removing trees and plants, and breaking up the soil structure of the banks.
