High Bank on Bayou Damaged by Bike Riders

Fools Dug Up Vegetation and Drove Boards Into Top of Bluff

But Boy Scouts Do More Good Deeds, Plant Vegetation

March 7, 2018

Riding a bike along the edge of a cliff above a river is bad enough. Even walking on top of a high bank can be damaging. But the high banks of Buffalo Bayou in Houston’s Memorial Park are already stressed and attempting to recover from the overbank flooding that came with Harvey last summer. Large sections of the bank slid away, taking down trees and vegetation. With time, however, the vegetation will grow back, the downed trees will collect sediment, and the banks will rebuild.

Now that recovery will be much more difficult. In the past weeks, off-road cyclists built a bike jump and wooden ramp right at the very edge of the bank near the main tributary draining the center of the park. This is very near the Bend in the River that Save Buffalo Bayou and photographer Jim Olive have been documenting through the seasons for the past four years.

The culprits apparently removed vegetation, dug holes, and drove large boards into ground. And then, of course, they’ve been pounding the edge of the bank with their bikes. They also dug up dirt to mound it into a jump further down the bank.

Representatives of the Greater Houston Off-Road Biking Association (GHORBA) condemned the construction.

“We would never approve this type of activity,” said C.J. Bernard, trails director for the biking association, in an email. “For anything we do at GHORBA related to trail development and maintenance, we follow the IMBA Sustainable Trails guidelines which highly emphasizes ways to identify potential erosion concerns and provides ways to eliminate and/or minimize.” (IMBA is the International Mountain Bicycling Association.)

“Most likely it is from a mountain biker that isn’t associated with GHORBA, as our trail stewards must approve features before they are built and this one, to my knowledge, was not,” wrote Christy Jones, president of GHORBA, in an email.

The dirt paths through the woods along Buffalo Bayou south of the Picnic Loop in Memorial Park are unofficial trails. However, they are much used by walkers and runners. Other trails in the park are officially open to bike riders as well as others. The neighboring Arboretum, however, does not allow bikers on its paths.

A representative of the Memorial Park Conservancy said the structure would be removed. “We are very grateful that you alerted us to this and will assess and remove the structure ASAP,” wrote Cara Rudelson, chief operating officer of the Memorial Park Conservancy, the private nonprofit organization running the public park. “We always have our eyes out for unauthorized use of the unofficial trails!”

Boy Scouts Plant Riparian Rebar on Bank of Buffalo Bayou

In the meantime, some more positive news: members of Boy Scout Troop 55 are doing good deeds again. This time, under the leadership of Boy Scout Austen Furse, who developed the plan for his Eagle Scout project, they planted 200 buckets of native eastern gamagrass on the upper banks of the ugly stormwater outfall, formerly a nature trail, also known as the Woodway Boat Launch, in the Old Archery Range of Memorial Park west of Loop 610. This happened Saturday morning, March 3.

Eastern gamagrass is an herbaceous stabilizer plant, described as “riparian rebar” and a “big, green leafy cousin of corn.” Though slow to establish, once established, eastern gamagrass can grow to six feet or more and has “extremely good root stability,” according to Your Remarkable Riparian, a field guide to riparian plants found in Texas.

Take note, property owners contemplating ugly and damaging concrete riprap for bayou banks.

Let’s hope the young gamagrass doesn’t get mowed down.

Austen is planning to photograph the site every week or two to document the results, says his mother, Anne Furse.

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?

Sept. 1, 2016

Updated Sept. 11, 2016

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.

Cool Off With Geology Classes On The Bayou

A Good Time for Floating with Tom Helm

August 13, 2016

You may think it’s way too hot to go outside. But it’s actually much cooler down on the bayou, thanks to the water and the shade from overhanging trees.

Also it’s free of mosquitoes since the damselflies eat them up. Nature works that way. Bats eat mosquitoes too. Mosquitoes don’t breed in flowing water anyway.

So now is the perfect time (unless it’s raining) to cool off and learn about the amazing geology of one of the last natural stretches of our 18,000-year-old Buffalo Bayou as it flows past Memorial Park.

Float for a couple of hours through this historic nature area with geologist, naturalist, and river guide Tom Helm. Tom will explain the ancient sandstone formations and high Pleistocene bluffs, the patterns in the sand, why the river changes course and how sediment taken away from one side gets deposited on the other. And much more. See mole cricket tracks and watch diving hawks! Witness the grace of a great blue heron flying in front of your canoe!

Right here in the middle of Houston.

Tom takes care of everything. Look under Classes at the top page of this website. Or contact Tom directly. Scheduling is flexible so arrange a time that suits you and your family and friends.

Get outside, have a good time, and learn something new! The water is low now so the sandstone formations and sandy banks are visible.

But if it’s raining or the flow is too high, classes will be postponed.

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.

Excavate fill

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.

Can An Urban Stream Restore Itself?

Yes, With Room to Move. Free Rivers Are Healthier and Better for Flood Control

By Susan Chadwick, Executive Director, Save Buffalo Bayou

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.

It’s for the Birds

Report on Plans for the Hogg Bird Sanctuary on Buffalo Bayou

May 11, 2016

First the positives about the presentation Monday evening, May 9, by the Houston Parks Board about plans for the little-known 15.56-acre nature preserve on Buffalo Bayou known as the Hogg Bird Sanctuary.

The sanctuary at the end of Westcott Street south of Memorial Drive is probably better recognized as the mostly impenetrable woods next to the parking lot for the Houston Museum of Fine Arts’ Bayou Bend Collection and Gardens, located across the bayou, accessible by a footbridge. Bayou Bend is the former home of the Hogg Family, who developed River Oaks and in 1924, along with partner Henry Stude, sold at cost to the city the 1,503 acres that became Memorial Park. (The Hogg Brothers also sold to the city at cost 133.5 acres of land intended to be part of Hermann Park. In 1943 the city sold that land for the establishment of the Medical Center, which provoked the continuing ire of their sister, Ima Hogg.) Ima Hogg, a cultural and civic leader and one of the city’s most revered philanthropists, donated the family house and gardens to the museum in 1957 and then donated to the City of Houston the woods on the north side of the bayou as a nature preserve.

Ima Hogg a Defender of Nature and Public Parks

Ima Hogg, who died in 1975, was also an ardent conservationist, early civil rights activist, mental health activist, and defender of park space for the public, in particular Memorial and Hermann parks. In her letters to city officials over the years, available in the archives of the Museum of Fine Arts, she described her firm belief that woodland parks should be kept as natural as possible and criticized in a 1964 letter to then Mayor Louie Welch, who famously thought public parks unnecessary, the “alarming situation” of rapidly diminishing park areas in Houston and “throughout America,” including through construction in the parks by “worthy institutions” that really ought to look for building sites elsewhere, she wrote. Miss Ima was still angry that the city had “relinquished so much of the acreage” in Memorial Park for highways and a golf course and in an earlier letter to then city director of public works, Eugene Maier, demanded that the money the city received from the state for the highway land be used to acquire and improve additional park sites. Let’s guess that probably didn’t happen.
