Beautiful Oaks Doomed on Memorial Park Golf Course?

Are Big Trees Part of Massive Tree Felling Project in Public Park?

 

March 21, 2019

Updated March 24, 2019

Strolling along Memorial Drive past the fence obscuring the secret remodel of the public golf course in Houston’s Memorial Park, we noticed these lovely old oaks tagged with ties and surrounded by plastic fencing. We were alarmed. Hundreds of other trees, including mature oaks and pines, are marked for felling with plastic ribbons all over the 1500-acre park, which has already lost innumerable trees as the $200-300 million Master Plan is bulldozed into place. But these trees were on the golf course. Could it be they were marked for preservation? Other trees already have been felled as part of the controversial $13.5 million “upgrade” of the popular course into a PGA Tour tournament-level course.

Waiting for An Answer

We’ve contacted the Memorial Park Conservancy, the private nonprofit that raises funds and manages the park for the benefit of the people of Houston. We’ll have an answer soon, we hope.

Update: Representatives of the Conservancy have responded that the renovation of the golf course for PGA Tour tournaments is the responsibility of the City of Houston Parks and Recreation Department and that we should ask HPARD about the trees. So we sent an email about the trees to HPARD Director Steve Wright late on Thursday, March 21, and we are waiting for a reply.

Developers Plan to Improve Memorial Park by Cutting a Lot of Trees, “Re-establishing” Streams

Business Group Requests Federal Permit for Dredging, Filling Wetlands, Hardening Tributaries to Buffalo Bayou

Public Comment Due by April 4, 2019

 

March 13, 2019

A Galleria-area development group has asked for a federal permit to fill wetlands and dredge and armor streams in Memorial Park in order to build two “earthen land bridges” over Memorial Drive. The project, part of a controversial $200-300 million landscaping plan for the public park, requires the felling of hundreds of trees, including mature pines, digging up and lining the streams with concrete rubble and wire baskets of “rocks,” covering Memorial Drive with concrete tunnels, and relocating playing fields and picnic areas.

The Harris County Improvement District 1, otherwise known as the Uptown Houston District or Uptown Tax Increment Reinvestment Zone (TIRZ) 16, is a local government corporation composed of property owners and developers and funded by local property taxes. In 2013 it was expanded to include Memorial Park, a 1,500-acre semi-forested park on Buffalo Bayou in the center of Houston.

The park, formerly the site of a World War I-era military training camp, is also a State Antiquities Landmark. (See also here.) Parts of a small constructed channel connecting the two originally natural though partially altered tributaries appear to be walled with stone possibly dating from that period. The two tributaries flow through deep wooded ravines lined with lovely dirt paths and empty in Buffalo Bayou.

“Rocks,” other than ancient sandstone, are not natural to Houston’s streams.

Public Comment Period Until April 4

The Improvement District last week filed an application for a permit from the US Army Corps of Engineers, which enforces the federal Clean Water Act. The Corps is seeking public comment on the permit application, including on whether a public hearing should be held. The public has until April 4 to comment. See below for how to comment.

Removing Trees on Buffalo Bayou Because It’s Cheap and Easy

A Stormwater Project with Little Benefit and A Lot of Uncounted Cost

 

February 26, 2019

A large number of trees will be cleared in one of the city’s last remaining public forests on Buffalo Bayou because it’s the “easiest and cheapest” stormwater project to do, city and county flood control officials explain.

The trees are being removed to dig out shallow basins on the bank of upper Buffalo Bayou in Terry Hershey Park in west Houston, a rolling wooded area with paths used by hikers and bikers and wildlife. When the bayou overflows, the basins are meant to hold briefly a modest amount of water which then continues flowing downstream.

But the calculation of “cheapest and easiest” does not include future repair and maintenance costs where now there are none. A similar project on the once-forested opposite bank has required many millions of dollars in taxpayer funds for maintenance and repeat repairs to the bank in the decades since trees were cut.

Nor does this calculation include the additional flow into the bayou from the loss of trees and vegetation, which significantly slow and absorb rainfall and runoff. A study by the University of Arkansas reports that removing forest can increase runoff into streams by as much as four or five times. (p. 3)

It does not consider the financial value that the forest provides by cleansing the water and the air for free. Studies have shown that riparian vegetation is cheaper and more effective at cleansing our polluted water than even sewage treatment plants. A study of Houston’s urban forest by the US Department of Agriculture found that even including invasive trees, our modest tree cover captures carbon and other pollutants from the air worth hundreds of millions of dollars.

Also not included: the value of the mental and physical health benefit that trees provide to Houstonians, who suffer from a deficit of nature, many of whom were traumatized by the flooding from Harvey. Since ancient times wise people have known that the experience of even a small piece of nature has health benefits. (See also here.)

Nature is the Best Engineer

Making room for the bayou to overflow is a good thing, as is a focus on detention or “slowing the flow.” Cutting down trees and removing vegetation next to the bayou is not.

“Engineers have a hard time understanding,” says Bob Freitag, director of the Institute for Hazards Mitigation Planning and Research at the University of Washington and co-author of Floodplain Management, A New Approach for a New Era. “Trees aren’t in their model.

“We want trees,” says Freitag. “Trees do a lot of good things.”

There is a new field of engineering that understands and imitates the process of nature, melding engineering and biology and valuing ecosystem services, points out Freitag. “But those who do it are few and far between. It’s a pretty new field.”

No Reduction in Flooding

The planned detention basins next to the bayou channel do not even reduce flooding, despite a popular belief that they will. Officials confirm that the small basins will do nothing to reduce flooding downstream. “No, they’re not going to save people from flooding downstream,” said Matt Lopez, the Harris County Flood Control District’s Precinct 3 coordinator. “They’re not going to save folks from Harvey or any other storm.”

Winter on the Bayou

The Cycle of Life

 

Feb. 22, 2019

(Updated Feb. 24, 2019)

We were late taking our winter shot of that bend in the bayou. We’ve been photographing the bayou from the same high bank in Memorial Park every season for almost five years now. But photographer Jim Olive has been busy taking photos of Joshua trees and palms in the sunny desert out in California. The clear air there is cleaner, drier, and healthier for his lady counterpart, so Jim, a lifelong East Texan, has pulled up stakes, driving back and forth to Texas for occasional gigs and resuscitating his many friends here with emergency storytelling. It turns out that Jim is a unique and irreplaceable person: a talented and generous professional photographer, a naturalist, herpetologist, passionately and actively devoted to the environment. Among other things, he is the founder of the Christmas Bay Foundation and also, not kidding, an actual Wilderness Advanced First Aid Responder, though that certification does not require lively storytelling.

The weather wasn’t cooperating on the days he was here. But finally last week there was a break in the gloom. Just after sunrise we met in Memorial Park, walked across the grassy picnic area south of Memorial Drive, and headed into the woods and down the winding dirt (unofficial) path with Jim reciting the Latin names of trees and plants.

Walking along one of the many ravines that drain into the bayou, we passed a pile of broken remnants of concrete pipe left over from when the park was part of Camp Logan, a World War I military training camp and hospital, now a State Antiquities Landmark. We paused to see whether the giant Texas rat snake (Elaphe obsoleta lindheimeri) that we saw coiled up in there a few seasons back would appear. It did not. This was not far from where we’d seen the big, beautiful coral snake (Micrurus tener) slithering across the path last November.

Dead Trees Giving Life

We continued down the trail, easily stepping over the disintegrating remnants of what was once a large log, the trunk of a massive Loblolly pine (Pinus taeda), possibly felled by the drought of 2010-2011. Dead trees are, in a sense, not really dead, as they continue to be a vital part of the ecosystem, both on the land, in the water, and along the bank. When we first started years ago, in order to pass over it, we had to step up on top of this fallen elder, with Jim cautioning always to give warning and be wary of the possible presence of a rattlesnake (Cortalus horridus) taking shelter under the log.

Wetlands, Flood Tunnels, and Rewilding Urban Neighborhoods

Texas gulf wetlands face population, development challenges

With urbanization and sprawl ongoing concerns in Texas cities, the question of how to build in ecological resilience grows more pressing. Kevin Sloan, a landscape architect in Dallas and professor at the University of Texas at Arlington, has been a big proponent of “rewilding,” a practice of designing green space to attract wildlife and reframe cities.

What is rewilding and why is it important?

What I, along with others, have come to use this word to describe is a process for how to approach environmental design. Everyone understands that for centuries architects have tailored building designs for the occupants those buildings shelter. If you’re building a house, there are private spaces, public living rooms. But even though we’ve built great gardens, parks, and exterior environments, we’ve never really asked what kinds of fauna these environments shelter. Of course when we design a park and plant trees, we know that birds will nest in those trees. But we’ve never made it anything deliberate.

We’re coming to realize that any exterior environment can be rewilded for a program of fauna that might include migratory pollinators, butterflies, honeybees, birds, maybe some small amphibians, and that the plant selections and design strategies account for – in a very deliberate way – the accommodation of those species.

Whether it’s a traffic island going into your motor-bank or an urban park or the Trinity River floodway corridor [in Dallas], you just ask the question: What could this area that I am about to affect reasonably accommodate for animals? And then design with that in mind.

Construction to Begin on Stormwater Basins in Forest of Buffalo Bayou

Flood Control Sends Notice to Residents Adjacent to Terry Hershey Park

 

Jan. 29, 2019

The Harris County Flood Control District has notified residents living on upper Buffalo Bayou in west Houston that construction of controversial stormwater detention basins on the forested south bank will begin soon.

The district sent an email, including a flyer about the project, to neighborhood leaders last Thursday, Jan. 24, asking them to spread the word that construction would begin in late January on three initial basins between Eldridge Parkway and Dairy-Ashford Road. The shallow linear detention basins require the clearing of trees and vegetation near the bank of the bayou. They would capture and temporarily hold about 100-acre feet of overflow from the bayou during a storm.

The district says in the flyer that it will attempt to preserve some trees and vegetation between the basins and neighboring property as well as along the water’s edge.

The district owns some 500 acres of land along the bayou for a little over six miles below Barker and Addicks dams. The bayou there was stripped and straightened by the Corps of Engineers in the late Forties. An analysis by Save Buffalo Bayou showed that straightening and narrowing the bayou there actually reduced its capacity, making future residents more vulnerable to flooding. At the time, the land—other than the natural riparian forest along the banks of the meandering bayou—was mostly agricultural.

Trees grew back, and the flood control district purchased the land from the Corps in the Sixties, leased it in the Nineties to Harris County for a public park named after environmentalist Terry Hershey, and began stripping trees again on the north bank for linear detention basins similar to those planned on the south bank. In the meantime, trails through the south bank woods became popular with hikers and bikers, and by 2012 local residents had formed a committee called Save Our Forest to fight plans to remove forest and excavate detention basins there.

Save Our Forest was largely successful until Harvey, after which the district revived its plans for a series of linear basins temporarily holding some 280 acre-feet of bayou overflow on the south bank between Highway 6 and Beltway 8.

Let the Bayou Expand Itself

In line with modern practice, Save Buffalo Bayou is in favor of slowing and holding stormwater before it floods a stream, not after. A better, more effective, less expensive approach would be to allow the bayou to restore its natural meanders, naturally lengthening and increasing the capacity of the stream, which is what it will keep trying to do anyway, eating away at the banks long ago weakened by artificial straightening as well as by ongoing digging and compressing by heavy equipment. Instead the county and the district spend millions repairing the unstable channel in order to keep it straight.

The district has already spent millions on the south bank linear detention basin project, including paying engineering firms for vegetation surveys and design. Lecon, Inc. has the $1.8 million contract to construct the initial basins scheduled to begin any day now.

Looking Back on 2018

Some Things That Did and Did Not Happen

 

January 15, 2019

The year 2018 was a year of adjustment and recovery for a city wounded physically and psychologically by the long-lasting impact of Hurricane Harvey in mid-2017.

Prior to Harvey, Save Buffalo Bayou and its supporters were able to stop a pointless, wasteful, and costly bayou “restoration” project that would have destroyed much of our public forest, a historic nature area, on Buffalo Bayou in Memorial Park, damaging and weakening the ancient high banks and the bayou’s ability to recuperate after floods. In fact, the project, if it had been completed, would likely have washed away during Harvey, as did many other “erosion control” and landscaping projects on the bayou. (See this nine-minute film shot over a year later, referenced below.)

But outdated flood management policy and practice remained in place. The rest of the world is adopting enlightened, practical, and cost-effective ideas like slowing the flow of stormwater (rather than speeding it up), getting out of the way of flooding, and managing flooding in place—practices based on understanding and mimicking nature. But misguided assumptions about streams and drainage—based on faith in heavy engineering and concrete—continue to circulate locally.

SBB spent the year following Harvey trying to explain science-based flood and stream management to distraught homeowners and panicked politicians: how rivers work, why they flood, and why straightening, deepening, and widening the entire length of the bayou (and the rest of our streams) would not work and would not help, and in fact would only make things worse.

That important discussion continues.

January

Shocker! Save Buffalo Bayou finds itself defending the Army Corps of Engineers which announces a project, called the Metropolitan Houston Regional Watershed Assessment, to study the big picture of drainage and flooding in the Houston region: where raindrops fall, how they move across rooftops and pavement and land, through drain pipes and into our bayous and streams, and ultimately into Galveston Bay. We need to be talking about this.

At the same time Save Buffalo Bayou continues its defense of forests on the bayou, opposing questionable Harris County Flood Control District plans to rip out trees in Terry Hershey Park to create a series of detention basins along the channel for holding a small amount of overflow from the bayou in exchange for allowing the City to send more water into the bayou.

Result: So far the detention basins have not happened, though they are still a threat. (See below.) But for now we still have soothing trees to hug and thank for deflecting, slowing, and absorbing the rain and for holding the bayou banks together, among other vital functions. SBB is in favor of detention. Slow the flow! But it makes no sense to cut down trees to create detention, since trees serve as natural detention devices.

And in case you missed it, here is geologist and Save Buffalo Bayou board member Tom Helm  explaining the origin of sand and the different kinds of sandstone in Buffalo Bayou. Because in January 2018 there was still a huge amount of sediment piled up the banks of the bayou downstream, and we were trying to explain to people where it comes from, why the banks slide away, and what can and cannot be done about that. (Hint: leaving some large woody debris, i.e. fallen trees, against the banks helps.)

Details of Memorial Park PGA Golf Agreement: Unanswered Questions. Who Benefits. Lack of Public Involvement.

An Open Letter to Houston City Council

 

Jan. 8, 2019

(Updated Jan. 28, 2019. The Houston City Council voted on Jan. 9, 2019 to allow the golf course plan to go forward. The Mayor’s Office has refused our Public Information request for the details of the plan, among other information.)

Dear Members of Houston City Council,

Regarding the agreement to transform the Memorial Park golf course into a PGA Tour golf course and hold an annual tournament there, I remain concerned about the financial benefit to the people of Houston and the lack of public involvement in this decision.

Houston is severely lacking in public park and green space. According to a 2018 report from the Trust for Public land, spending on public parks in Houston is about half the national median expenditure per resident. Houston ranks 77 out of the 100 largest cities in the country for park access and amenities, receiving an overall park score of 37.5 out of 100.

These figures are no doubt well known to you. But it’s not just a matter of park equity for Houstonians. Our city has been suffering from severe flooding and likely will experience increased flooding. Trees, vegetation, green space are vital for slowing and absorbing the rainfall and runoff that rapidly overwhelms our drainage system, including our streams and reservoirs. Not to mention the role of trees and green space in absorbing carbon dioxide.

A $1 million donation to the city parks department, as proposed by Council Member Laster, is an improvement to the proposed agreement. But what percentage of the tournament revenue is that? How much profit will the Astros Golf Foundation and the PGA Tour be making from this tournament in our great public park? We don’t know. Maybe it’s a generous donation. Maybe not. The PGA Tour, as noted previously, reports revenues of over $1 billion annually. Yes, both organizations give money to charities of their choosing (and making). But if it’s our public park being used to make money, why shouldn’t we get to choose? Shouldn’t more of the revenue be directed towards our public parks generally? The parks department and our city council representatives should decide where the money should go – and more money should go towards more green space.

We have been told very little about the financial details of this agreement because there have been virtually no public meetings about it. I have previously complained that this change in use of public parkland requires public notice and a public hearing under state law, specifically Ch. 26 of the Texas Parks and Wildlife Code. This complaint has been ignored.

Will local people be hired to do the work building the stands, running the event, etc.? Or will the PGA Tour bring in its own people from outside the area?

No one has asked the people of Houston whether they want this golf tournament in our lovely forested park on Buffalo Bayou. Maybe they do. We don’t know.

The proponents claim that the city overall will see a $50-90 million benefit from the economic impact of the week-long tournament annually. Dr. John Crompton, Distinguished Professor in the Department of Recreation, Park and Tourism Sciences at Texas A&M, did a study of the Phoenix Open some years ago. In a recent email, he said that his estimates showed “total expenditures from external visitors amounted to $29.5 million with an economic impact on incomes in the local economy of $22.4 million (this is the appropriate measure of economic impact).”

I urge you, please, to ask more questions at your council meeting on Wednesday, Jan. 9.

Thank you.

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.
