Spring 2017 on Buffalo Bayou
Never the Same River Twice
March 18, 2017
Out on Buffalo Bayou early this morning, Saturday, March 18, 2017, with photographer Jim Olive. We were looking for our Spring 2017 shot of the same bend of the bayou we have been documenting for the last three years throughout the seasons. Flow was low base flow, about 150 cubic feet per second. Birds singing. Frogs burping. Squirrels quarreling. Warmth wafting off the water. Was foggier than Jim had hoped, and he had to be patient, as always, for just the right shot. We’d been waiting for a clear morning for days.
For the entire series see A Bend in the River under Photos and Films. This scene is in the historic nature area targeted for destruction and “restoration” by the Harris County Flood Control District, the Memorial Park Conservancy, and the Bayou Preservation Association.
An update on that costly, misguided project, which sadly still threatens, is coming up next.

State of the Bayou
Downed Trees. New Channel. New Riprap. Washed Out Sidewalks, Beavers, and Turtles
But Some Banks Naturally Rebuilding
Does It Make Sense to Repair?

You could not step twice into the same river. Heraclitus
We finally had a chance recently to float down beautiful Buffalo Bayou to see how things have changed. Our trip took us past Memorial Park in the middle of Houston. We also biked along the bayou through Terry Hershey Park far upstream in west Houston below the dams to see what was happening there.
The good news is that some of the high banks that had slumped in Memorial Park and the Hogg Bird Sanctuary during the Memorial Day 2015 flooding are naturally rebuilding.
The bad news is that the River Oaks Country Club has added more riprap to the south bank, hard armoring the bank with ugly, damaging concrete rubble, including where it should not be.
Nature’s Miraculous Way of Restoring. For Free.
Houston has had multiple record-breaking rains and flooding since the spring of 2015. When Buffalo Bayou overflows its high banks, as it did in the Memorial Day flood of 2015, the banks in places sometimes slump or slide away. This happens when the overflowing water seeps through the ground and saturates layers of sandy clay that liquefy, sometimes causing the bank to give way. Buffalo Bayou is 18,000 years old, and this has been happening for a very long time.
This natural tendency to slump is one reason why we think attempting to engineer these banks as proposed by the $6 million Memorial Park Demonstration Project won’t work. It’s also the reason why we think building and repeatedly repairing sidewalks at the bayou’s edge is wasteful and foolish.

It’s Not Dead Yet
Flood Control Still Pushing Costly, Destructive “Stabilization” Project on Buffalo Bayou
July 31, 2016
It’s a pointless, wasteful, ill-conceived, and maybe illegal project to rip up and raze trees and plants and wildlife habitat, dig up the banks, plug up tributaries, dredge and reroute the channel along one of the last natural stretches of Buffalo Bayou in Houston. This is a dreamy stretch of the river in the middle of the city, filled with beaver, otter, alligators, fish and flying creatures, and even edible plants. It flows for more than a mile past our great public Memorial Park, a natural detention area and significant geologic site that features very old high bluffs and sandstone formations. All of which would be obliterated.
And after almost three years of adamant public opposition, the Harris County Flood Control District is still promoting the project, which will cost the taxpayers at least $4 million plus, not including future costs of maintenance and repair.
It’s mystifying why they want to do this, why they think it would even work, why they don’t realize that the bayou would wash it away or that it would simply all slump away, as has happened in Buffalo Bayou Park downstream, where taxpayers are footing the ever-mounting bill for constantly repairing the banks dug up and stripped of trees and vegetation by Flood Control.
Do They Not Have More Urgent Problems?
Surely, the flood control district has more urgent problems that require our hard-earned tax money. Harris County is one of the most flooded places in the country. And this project, billed as a “stabilization” and “bank restoration” program, will do nothing to address flooding and could even make it worse. The county should focus on the hundreds of miles of channelized bayous and streams unwisely covered in now-aging concrete that should be restored to something more natural and beneficial.
The project, called the Memorial Park Demonstration Project, was first proposed in 2010 by the Bayou Preservation Association under then board chair, Kevin Shanley, landscape architect and principal with SWA Group, the firm responsible for the ugly, obtrusive bridges, collapsing sidewalks, poorly-functioning dog park and non-functioning faux Hill Country fountain and stream in Buffalo Bayou Park.
This map prepared by the Harris County Flood Control District shows the areas to be excavated (yellow) and filled (orange) in the proposed Memorial Park Demonstration Project. Note also the rerouting of the channel. Memorial Park and the Hogg Bird Sanctuary, including a tributary, are on the north, with houses in between. The entire south bank is River Oaks Country Club golf course.
The Flood Czar Answers His Own Phone
But What Causes Urban Flooding?
July 12, 2016
Steve Costello explained for probably the hundredth time or more that he is not really the flood czar of Houston but the chief resilience officer.
The soft-spoken Costello, a civil engineer, former member of the Houston City Council (serving six years), former president and current board member of the Memorial Park Conservancy, and former candidate for mayor of Houston, was speaking at a meeting of the Briar Forest Super Neighborhood in west Houston a few weeks ago. Buffalo Bayou runs through the Briar Forest Super Neighborhood.
Appointed by Mayor Sylvester Turner in early May, Costello has been making the rounds, speaking at public meetings, attending others, such as the highly emotional town hall meeting with US Rep. John Culberson in June. Costello also has been giving interviews. Recently he flew off to Washington D.C. with the mayor and members of the Houston City Council to meet with officials of the Army Corps of Engineers about a multi-billion dollar plan to dredge and deepen Lake Houston in order to enlarge its capacity and alleviate flooding in northeast Harris County. Lake Houston is a major source of Houston’s drinking water.
But back in late June he was explaining to the Briar Forest crowd of about twenty-five neighborhood activists that while his sole mission was to do something about flooding, and his wife liked the idea of being a czarina, really he was the chief resilience officer. The concept, he explained, was a response to the Rockefeller Foundation’s 100 Resilient Cities project. Mayor Annise Parker had applied to the program for funding and support for a resilience officer, who would have focused not just on flooding but also on broader social issues like unemployment and transportation. Mayor Turner decided he wanted to focus on drainage and flooding, and the Rockefeller Foundation decided not to fund a position for Houston, said Costello.
No Staff and No Budget
As a result, Costello answers his own phone and emails himself. He has no staff. Apparently he has no funds or budget. (He also said in a later email exchange that he wasn’t sure where the funds for his salary were coming from and didn’t answer how much he was being paid.) Yet he has been bravely handing out his card, offering his cell phone number and email to myriad people in a city drowning in outrage and misery over increasing and repeated flooding, lost homes, cars, property, savings, and lives.

Can An Urban Stream Restore Itself?
Yes, With Room to Move. Free Rivers Are Healthier and Better for Flood Control

This article is adapted from a presentation made at the Southwest Stream Restoration Conference in San Antonio, Texas, on June 2, 2016.
Save Buffalo Bayou is a non-profit organization founded two years ago to fight a public project described as a “restoration” project on one of the last natural stretches of Buffalo Bayou as it flows through the middle of Houston, past 1,500-acre Memorial Park and another 15-acre public nature preserve, the Hogg Bird Sanctuary. Since then our organization has expanded into broader, related issues. But today’s topic is restoration.
Here are some of the most common responses I would get when I would say that this mile-long plus stretch of the bayou is natural, along with what were some of the most common defenses of the project.

The river’s not natural because the river changes.
It’s not natural because it’s been altered by high runoff from urbanization.
Trees fall into it.
It has terrible erosion problems. Look at those steep high banks!
It’s terribly eroded. Look at those sandy banks!
It’s eroding terribly. Sediment from the banks in Memorial Park washes up on the sidewalks of Buffalo Bayou Park we built downstream in the floodway right next to the river.
All that sediment carries bacteria. If we stop the banks from eroding so much sediment, we will reduce the bacteria. (Although sediment-laden Buffalo Bayou is less polluted than White Oak Bayou, which runs relatively clear and extremely foul due to being encased in concrete.)
And of course the big one: the river needs to be stabilized because it moves around.
Then there’s the argument, both implied and explicit, that prompted me to select this topic for presentation today: an urban stream cannot restore itself.
A Profound Misconception About How Nature and Rivers Work
All of those statements, of course, indicate a profound misconception about nature, about how a river works and how rivers benefit us.
A river is a living symbol of change. A living system. A dynamic process of nature that works for our benefit. Even the simple grains of sand work on our behalf to cleanse the water.
Cottonwood Down
A Giant Falls
June 14, 2016
We have been watching this magnificent cottonwood on the south bank of Buffalo Bayou in Buffalo Bayou Park. Beginning in 2012 the Harris County Flood Control District realigned the banks and removed a lot of trees and stabilizing vegetation from the banks of the bayou between Sabine and Shepherd streets for its “natural stable channel design” improvements in the park.
Those “channel conveyance” alterations left many of the few remaining large trees on the weakened banks in a vulnerable state. In the Fall of 2015 part of this grand old tree broke apart.
And now, finally, sadly, the great tree has fallen. Others will go eventually.
Big trees fall into the bayou all the time. It’s part of the natural process, and fallen trees collect sediment for bank building, provide fish and wildlife habitat, and slow storm waters. But trees, whose massive roots help hold the bank together, are not supposed to fall in the water because in the name of progress we dug up and destroyed the structure of the surrounding banks, breaking up the intricate root systems of the vegetation that had been there for a very long time.
Still, we have had unusually high rainfall and stream flow in our bayous. The banks in many places are now lush with new green growth and wildflowers. For nearly two months we have had record high flows in Buffalo Bayou as the Army Corps of Engineers attempts to empty the flood control reservoirs behind Barker and Addicks dams in western Harris County. We have reports of trees downed all along the bayou.
Watch this slideshow of the great cottonwood as it maintained its lonely vigil until the end.

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.

Cutting, Removing Fallen Trees on Bayou Banks is Wrong
Brush Creates New Banks and Needs to Stay
Aug. 28, 2015
Updated Aug. 29, 2015, with a response from the Harris County Flood Control District.
We were afraid of this.
Big floods are powerful. Anyone who has lived on or spent any time on a river in the wild knows that a river can rearrange its banks with an awesome, even frightening force. Yet floods in nature are necessary.
Buffalo Bayou is an 18,000-year-old river, our Mother Bayou. We are privileged to have a forested stretch of the bayou passing through the middle of the city in our great public Memorial Park. But during the Memorial Day flood and the record-high water released by the Army Corps of Engineers from the upstream dams during the days that followed, the rushing bayou took down trees and shrubs in Memorial Park, the Hogg Bird Sanctuary and elsewhere. The bayou was reordering its banks, replenishing and reseeding the floodplain, adjusting to the changing flow, as it has done for a very long time.

Not all of this was erosion exactly. Our geologists explain that some of it was slumping caused by the overflowing of the banks. The overflowing floodwater saturated the high ground and seeped into the internal layers of clay soil that turned to pudding and slid out, creating the concave look that you see on some of the banks. This particular slippery geologic makeup of Buffalo Bayou is one reason why we believe the Harris County Flood Control District’s costly and misguided $6 million “stabilization” project, known as the Memorial Park Demonstration Project, won’t work on the high banks of our untamed Buffalo Bayou, a rare natural asset to have and learn from in the middle of the city.
Our Muddy, Maligned, Mistreated Bayou Knows Better
But trees and brush falling onto the banks (and into the water) is part of a natural process, an important natural rebuilding process. The brush collects sediment from the waters of the bayou, building up new banks that the bayou replants with stabilizing and colonizing native vegetation. Yes, amazingly, our muddy, maligned and mistreated living bayou does that, with its own superior intelligence and life force. The bayou restores itself, replenishing its important ability to filter pollutants, neutralize bad bacteria, cleanse the water, protect against further erosion and provide aquatic habitat, among many other important functions, including trapping our trash and plastic debris before it ends up in the bay and oceans.
