Flood Control Project Would Destroy Vital Wildlife Habitat
Buffalo Bayou protects diverse wildlife and acts as corridor
Predators help control control diseases by consuming rodent and insect pests
Mosquitoes more dangerous than coyotes
The Houston Chronicle recently published an informative article about wildlife in the city. It has special relevance to Buffalo Bayou at a time when the Harris County Flood Control District, supported by the City of Houston, the Bayou Preservation Association, the Memorial Park Conservancy, and the Buffalo Bayou Partnership, is planning to destroy nearly 1.5 miles of one of the last natural stretches of Buffalo Bayou as it flows past Memorial Park and the Hogg Bird Sanctuary.
Wild animals in the city: It’s time to stop being surprised
Gray Matters, the Houston Chronicle, July 1, 2015
Several times this spring, coyotes made national headlines when spotted roaming the streets of New York, from Manhattan to Queens.
In recent years, a host of charismatic wild species, the coyote being only the most famous, have returned to American cities in numbers not seen for generations. Yet the official response in many areas has been, at best, disorganized, and people’s responses varied. The time has come for us to accept that these animals are here to stay, and to develop a new approach to urban wildlife.
Most big American cities occupy sites that were once rich ecosystems. Large parts of Houston, Chicago, and New Orleans rest atop former wetlands. New York and Boston overlook dynamic river mouths. San Francisco and Seattle border vast estuaries, and even Las Vegas sprawls across a rare desert valley with reliable sources of life-giving fresh water, supplied by artesian aquifers the nearby Spring Mountains. All of these places once attracted diverse and abundant wildlife.

Permeable Paving Can Help Save Us and Our Bayous
Impervious Surface Is A Major Cause of Flooding in Houston
Yes, porous paving does work in Houston. We need to use more of this, on our hot, sunbaked parking lots, on our sidewalks, driveways, patios, and more. (It’s cooler too!)
Storm water runoff is a major problem for our bayous (especially those that have had protective trees and plants stripped from their banks). And impervious surface is the major cause of flooding and contributes to water pollution too. Instead of soaking into the ground (or being deflected by trees and leaves), filtering naturally and slowly through the soil and being cleansed of pollutants, storm water runoff gathers quickly, racing through toxic streets and highways, into drainage systems and pouring all at once into our bayous and creeks.
Here is an interesting and timely article in the Houston Chronicle by the founder of Houston-based TrueGrid, a permeable paving company that even creates permeable grass parking lots.
(Note to Houston park and street planners: we don’t need to have ugly, hot impermeable concrete or asphalt sidewalks to accommodate wheelchairs and runners. TrueGrid makes ADA compliant, permeable sidewalks.)
There is, in fact, also a permeable asphalt, recommended by the Environmental Protection Agency (EPA).
But here’s another interesting fact: in a typical urban residential area, rooftops account for 30-40 percent of the total impervious area. What can you do about that? Individuals can do a lot!
As the EPA says, “Slow it down, spread it out, soak it in.”
We don’t need to keep flooding and destroying our bayous, making them into bigger, uglier drainage ditches.
Leave It Alone: Buffalo Bayou Will Naturally Repair Itself
Opponents of the Memorial Park Demonstration Project Say Buffalo Bayou Is Fine Post-Flood
By Dianna Wray, Houston Press, Wednesday, June 10, 2015
After the rains started coming down on Memorial Day weekend, geologist Bill Heins, an ardent opponent of the Memorial Park Demonstration Project, couldn’t stop thinking about what was happening as the waterway continued to swell and slop over its usual banks along the last natural stretch of Buffalo Bayou that exists in Houston.
The flood waters haven’t fully receded yet, but both those in favor of the project and those against it have been out on the bayou looking for anything to back up their arguments. Project proponents point to signs of erosion on the soggy banks as evidence that we need this project. Those against it, including Heins, argue that the banks are showing signs of only minor erosion and that the evidence so far shows the natural system of the bayou — even during a record-setting flood — is working perfectly, meaning the Memorial Park Demonstration Project is unnecessary.
What Flood Control Is Not Telling Us
“Maintenance” Road Planned Along Bulldozed Bank
Updated June 8, 2015. See below.
Updated June 7, 2015. See below.
The Harris County Flood Control District is planning to create a 12-foot wide pathway for maintenance vehicles along the graded bank of Buffalo Bayou in Memorial Park.
The maintenance road parallel to the bayou is not included in the plans to “restore” the wild banks of the bayou submitted to the Army Corps of Engineers by the flood control district.
The district revealed the plan for what it is calling a “Monitoring Access Zone” at an invitation-only meeting Tuesday, June 2, 2015. The meeting was one of a series to develop a planting plan for the $6 million “erosion control,” “bank restoration,” “water quality improvement,” “flood conveyance” project known as the Memorial Park Demonstration Project. Apparently the planting plan is not progressing well, as at the meeting the district proposed planting tall fescue, an invasive exotic almost impossible to control. Tall fescue has been the scourge of Texas prairies for several decades at least.
“Tall fescue forms a near-monoculture and is responsible for the loss of otherwise undisturbed prairie remnants throughout Texas and the Midwest,” reports one of our landscape ecologists.
Well, so much for the district’s native plant expertise and commitment to a native-only riparian forest.
No trees, no “better than ever” riparian forest
Little is known about the previously undisclosed but long-suspected “Monitoring Access Zone.” According to a source who was at the meeting, the 12-foot wide pathway will be planted with some sort of seed mix for several years until the district is certain the “restored” banks will hold. They won’t hold, of course, so this grassy, flat “access zone” is likely to be permanent.
Which means no trees, no “better than ever” riparian forest and wildlife habitat, banks bulldozed and leveled even through the so-called “no-work zones.”
What is Federal Jurisdiction
The district explained at the meeting that it was not required to reveal the “monitoring” road to the Army Corps of Engineers because it does not impact federal waters, presumably because the road will be above the Ordinary High Mark, which is the lateral limit of federal jurisdiction.
But it will not be above the OHWM, which in a significant section of the park extends deep into the forest as part of the flood plain, a natural detention area, including swales and wetlands, all of which are under federal jurisdiction. The road and the “bankfull bench” upon which it will sit will also fill and block at least two tributaries, which also are under federal jurisdiction, although on its plans the district labels both tributaries “gullies,” thereby attempting to remove the tributaries from federal jurisdiction. (See sheets 16 and 18.) Gullies are classified as an “erosional feature” by federal law. An actual gully leading from the South Picnic Loop parking lot is oddly labeled a “tributary.” (See sheet 16.)
So far we don’t know the length of “Monitoring Access Zone,” whether it extends along the entire north bank of the project area, including private property, or whether a “Monitoring Access Zone” will also be built on the south bank of the project, land which belongs to the River Oaks Country Club.
Guess we’ll have to ask the flood control district. And object to the Corps.
What else is the flood control district not telling us?
Update June 7, 2015
There is no “road” planned for maintenance vehicles on the wild banks of Buffalo Bayou targeted for “restoration” by the Harris County Flood Control District.
Jason Krahn, manager for the district’s controversial $6 million project to “improve” one of the last natural stretches of Buffalo Bayou, wrote in an email to Save Buffalo Bayou on June 5 that “there is no road proposed for the post construction monitoring activities associated with MPDP [Memorial Park Demonstration Project].”
Participants in the district’s Vegetation Advisory Workgroup for the dredging and channelizing project had been told that for several years after “restoration” there would be a grassy 12-foot wide “Monitoring Access Zone” for maintenance vehicles to access the bulldozed and reconstructed banks of what is now a perfectly healthy historic natural area in need of no monitoring or maintenance whatsoever.
This “Monitoring Access Zone,” workgroup participants were told, would remain in place until there was no longer any need for monitoring, replanting, watering, removal of noxious invasive vegetation, or repairs to failing “stabilized” banks, etc. Presumably removal of noxious invasive vegetation would not include the tall fescue, a noxious invasive plant, described above, that the district earlier this month was contemplating planting. Responding to objections, the district reportedly has changed its mind about the tall fescue.
Krahn said that monitoring activities would take place on both the north and south banks of the bayou in the project area, which includes Memorial Park and the Hogg Bird Sanctuary on the north and the River Oaks Country Club on the south.
He also wrote that “no work zones” on the bayou were in fact “no work zones,” despite the fact that heavy equipment would be driven over the banks, according to the district’s plans. However, above the Ordinary High Water Mark these “no work zones” would not be graded into bankfull benches, wrote Krahn, because “these are portions of the project area that already have the necessary geomorphic characteristics for a sustainable, stable channel.” A bankfull bench is a flat or sloping area above the bank of a stream that slows overflowing floodwater.
Asked to clarify the “Monitoring Access Zone,” Krahn has not yet replied.
But it’s not a “road,” Krahn insisted. So we won’t call it a “road.”
How about sendero?
Updated June 8, 2015
Project Manager Jason Krahn has clarified the “monitoring access zone.” In an email to Save Buffalo Bayou Monday morning, Krahn wrote:
“To provide for the monitoring access as outlined in the Atkins report [the post-construction monitoring plan included in the revised permit application], the District is working to define the appropriate spacing for vegetation within a portion of the flood plain planting zone. A spacing of 12-foot in width is currently being considered to allow for this access, or ‘monitoring access zone’ as you’ve referenced it in your previous email correspondence.”
Immutable Plan. Invisible Rocks.
“Revised” plan to destroy Buffalo Bayou not really “revised” at all.
Project manager says no significant changes to much criticized original plan.
No sandstone in project area, says flood control, contradicting itself.
Despite the hundreds of comments criticizing the purpose, methods, impact, cost, benefit, and harm of Harris County Flood Control District’s proposed “erosion control” project on Buffalo Bayou in and around Memorial Park, the district has made no significant changes to the plans recently re-submitted to the Army Corps of Engineers.
Jason Krahn, project manager for the controversial Memorial Park Demonstration Project, told Dianna Wray of the Houston Press that the district was “simply following the guidelines” and that there were “no significant changes” to the original project plan.
Indeed, many of the “revised” plan sheets posted by the Army Corps of Engineers on its website appear to have been simply relabeled with new dates, though there are some with new details.
The public has until June 5 to send comments to the Corps about the district’s “revised” permit application and the district’s responses to previous comments. There is no limit on the number of comments one can make. So if you’ve already made a comment, make another!
Revised plan to destroy Buffalo Bayou announced: Public has till June 5th to comment
Updated May 15, 2015.
Today, May 5, 2015, the US Army Corps of Engineers posted a new public notice announcing a revised permit application from the Harris County Flood Control District to destroy nearly 1.5 miles of one of the last natural stretches of Buffalo Bayou in Houston. The flood control project, called the Memorial Park Demonstration Project, is in a historic natural area with high cliffs and sandstone formations hundreds of thousands of years old.
Comments must be submitted by June 5, 2015.
The Flood Control District’s first application was announced in a public notice last April, and public comments were received through June 30. The comments were overwhelmingly negative. The revisions to the permit application are in response to those comments.
The Corps is now soliciting comments from the public, governmental agencies and officials, and other interested parties in advance of making a determination about the permit application. The Corps requests that comments be limited to the clarifications and updates made by the Flood Control District to the Memorial Park Demonstration Project plans, monitoring plan and planting plan, as well as the District’s responses to comments received by the Corps and made by the Corps. The summary of updates and clarifications are contained in the following document under the “Response to Comments” tab on the Corps’ website:
You can read the revised plan here.
Houston and Harris County taxpayers are funding $4 million of this destructive “restoration” project, which would shorten, reroute, dredge, and channelize the bayou, eliminating a healthy riparian zone and rebuilding it using “natural, stable, channel design” methods prone to failure. The River Oaks Country Club, which owns the entire south bank of the “restoration” project, is paying $2 million. Riparian zones are crucial to the cleanliness of our waters, and are generally protected by policies and programs of our state and federal governments.
The north bank of the project is mostly Memorial Park and the Hogg Bird Sanctuary, with some private property in between.

Your Time Is Up: Cohen Cuts Off Criticism of Costly Memorial Park Plan
What’s the Rush?
Full Council to Consider Unfinished $3.2 Million Plan Wednesday, April 1
Public Comments to Council on Tuesday, March 31
Update Monday, March 30: Council Member Steve Costello’s office has responded that as a member of the board of directors of the Memorial Park Conservancy, he will recuse himself from voting on the proposed master plan.
Public comments were limited to two minutes due to the large number of people signed up to speak on the city’s proposed master plan to spend $200-300 million on Memorial Park. A few of the nine members of the council’s Quality of Life Committee, chaired by Ellen Cohen, met last Wednesday afternoon to hear Parks Director Joe Turner and landscape architect Thomas Woltz present the ambitious, vague, and costly master plan for the 1500-acre-plus woodland park.
Dozens of people spoke in favor of the plan. Most of them were members of the board of or connected to the Memorial Park Conservancy, and many of them, users of the park, gave moving testimony about their reasons for joining the conservancy: the devastating impact of the 2011 drought, which has killed more than half the trees in the park.
But there were also strong critics of the unfinished $3.2 million proposal, which so far does not seem to be an actual written plan specifically identifying and prioritizing what should be done and when, two key elements for a successful master plan, according to a recent report on urban park conservancies from the Trust for Public Land.
A large contingent of critics were residents or property owners adjoining the park concerned about the increase in traffic, noise, lights, and people using the park. A smaller group of conservationists also expressed concern about the increase in traffic and parking, the loss of trees and natural areas, the expense, inappropriate planting plans, and lack of detail about costs and maintenance. It was suggested that new facilities be placed instead in new parkland purchased with some of the millions of public dollars to be used for the project.
The new master plan proposes to increase parking by thirty percent. However, the 2004 master plan for the park, much of which has never been carried out, identified parking lots as “undesirable intrusions on the natural landscape” and recommended “no net change to the quantity of daily use parking spaces” in the park. To manage peak demand, the 2004 plan recommended the use of shuttles and the construction of “an ‘over-flow only’ parking using environmentally sensitive construction techniques along the rail and power line right of way.”
The Blinged-Out Master Plan for Memorial Park
City Council Quality of Life Committee Should Send Expensive, Overdone Master Plan Back to Drawing Board
The Memorial Park Conservancy is sending its $3.2 million unfinished master plan for Memorial Park to the Houston City Council’s Quality of Life Committee on Wednesday, March 25. The plan is so far a gaudy, overstuffed mish-mosh of bad, hazy, contradictory, wrong, and incomplete ideas developed apparently with the main goal of spending some $200-300 million, half of it public money.
The committee should reject this tacky, impractical document and consider directing hundreds of millions of dollars towards the purchase of new parkland instead.
Among other things, the plan misleadingly describes Buffalo Bayou as it flows along Memorial Park as “altered.” A slide shown at the final presentation of the plan to a packed audience at the Museum of Fine Arts Houston March 9 outlined the bayou in bright red and identified it as “altered Buffalo Bayou.” (See slide 18.)
We were stunned. Reasonable people would assume that “altered” meant channelized, dug up, scraped, engineered, rebuilt, etc. by humans or machines. In fact, the bayou flowing past Memorial park is one of the last unaltered stretches remaining in the city.
But no, “altered” in this case means “changed over time,” explains Shellye Arnold, executive director of the park conservancy. The bayou has adjusted to increased water flows from increased runoff due to development and paving; therefore the bayou is “altered,” says Arnold in an email.
The conservancy is developing the ten-twenty-thirty-year plan with the Houston Parks and Recreation Department and the Uptown TIRZ 16, which is funneling our tax money into the blinged-out project. It’s not clear who is in charge of the master plan, or even who is now in charge of Memorial Park, for that matter.
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.

In Memory of Frank Salzhandler, Longtime Defender of Buffalo Bayou
Longtime environmentalist and defender of Buffalo Bayou Frank Salzhandler died unexpectedly last month at his home in Houston’s Cherryhurst neighborhood. He was much too young.
Frank was a respected activist and the founder in 1989 of the Endangered Species Media Project, a nonprofit organization that graciously sponsored Save Buffalo Bayou before it became an independent nonprofit last fall.
We offer this opportunity to listen to the River Oaks Chamber Orchestra playing the lovely Buffalo Bayou Suite in honor of Frank Salzhandler.
