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.
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:
us290amtstudy@hcpid.org
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 us290amstudy@hcpid.org 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.

A Roundup of Opinion on What Happened and Why

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.

Support Your Forest on Buffalo Bayou
Annual District G Meeting with City Officials Thursday, March 3
March 2, 2016
Citizens concerned about our forests on Buffalo Bayou will want to attend the annual District G Capital Improvement Plan meeting tomorrow evening, March 3, 2016. The meeting starts at 6:30 p.m. in the Stratford High School Auditorium, 14555 Fern Drive, and features the district’s new city council member, Greg Travis, who was elected to City Council District G last November.
Capital Improvement Plan meetings “afford citizens an opportunity to learn, voice their concerns and address their respective City Council Members and City of Houston officials regarding project planning and delivery,” according to a statement on Travis’ website.
District G extends along Buffalo Bayou from Shepherd Drive to Barker Reservoir in far west Houston.
Members of Save Our Forest, which was successful last year in persuading the City of Houston to drop its plan to raze forest in Terry Hershey Park for a stormwater detention basin, are urging citizens to “show your support for the forest to our new City of Houston administration.”
“We now have a new city council representative, a new mayor and a new [Public Works and Engineering] director since we began our campaign to Save Our Forest,” wrote community activist George Crosby in an email. “It is important that they know how much you care about Buffalo Bayou.
Detention Alternatives Without Destroying Forests
“Last year there were two major rainfall events which caused structural flooding in Houston. Regional detention alternatives that can reduce local flooding without having to destroy the forested areas of Buffalo Bayou are not happening. Cooperation between the City, County and Federal governments is required for a successful regional detention initiative.
“A cooperative inter-governmental effort begins with the City of Houston understanding our support for this approach. Please help us give emphasis to Save Our Forest,“ wrote Crosby.
The public forests of Buffalo Bayou are still threatened by a Harris County Flood Control District plan to build some 24 detention basins on both banks of Buffalo Bayou in Terry Hershey Park.
The flood control district is also waiting for a federal permit to raze the forest along more than 1.25 miles of one of the last natural stretches of the bayou as it flows past Memorial Park and the Hogg Bird Sanctuary.
It makes no scientific sense to destroy forests to create detention basins. Forests provide valuable natural detention by slowing, absorbing, and deflecting rainwater, in addition to many other valuable ecological services, including cleansing and filtering the water and protecting against erosion.
In October of 2015, the Obama administration issued an executive order directing all federal agencies to incorporate the value of ecosystem services in their decision-making.
In addition, the Harris County Flood Control District is obligated by state law to conserve forests. (PDF. See page 6.)
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.

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.

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.

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 .
