Buffalo Bayou Flood Bond Meeting

New Meetings Scheduled

June 28, 2018

Updated July 23, 2018

The Harris County Flood Control District has scheduled new meetings, including a meeting on Buffalo Bayou for July 30, to explain the proposed projects to be funded with to be funded with $2.5 billion in proceeds from the bond election to be held Aug. 25.

Officials with the Harris County Flood Control District are holding public meetings in each of the county’s 23 watersheds to receive public input about proposed flood mitigation and protection projects.

The meeting on projects related to Buffalo Bayou will be held on July 30 from 6 to 8 p.m. at the Memorial Drive United Methodist Church, 12955 Memorial Drive, Houston 77079.

County officials have recently held meetings on projects near Addicks Reservoir, which drains into Buffalo Bayou, and Cypress Creek, which overflows and drains into Addicks during floods. Politicians and others are proposing a new dam somewhere on Cypress Creek to deal with flooding there, although a new dam would be a federal responsibility, not a local project.

Stormwater draining into Addicks Reservoir is an acute problem as the too much runoff during Harvey forced federal authorities to open the floodgates during the storm, flooding thousands of homes and killing three people along Buffalo Bayou. The stormwater capacity of Barker Reservoir, which also drains into Buffalo Bayou, is also a problem. Among other issues, residential subdivisions were developed within the known flood pool behind the dam and many homes were flooded during Harvey.

A meeting on Barker Reservoir projects is scheduled for August 1 from 6 to 8 p.m. at Memorial Parkway Junior High School, 21203 Highland Knolls Drive in Katy 77450.

The location for the July 10 meeting about projects related to the San Jacinto River has been changed. The new location is Kingwood Park High School, 4015 Woodland Hills Drive in Kingwood, 77339, from 6 to 8 p.m.

Also upcoming is a meeting on projects related to Little Cypress Creek. That meeting is scheduled for July 31 from 6 to 8 p.m. at the Richard & Meg Weekley Community Center, 8440 Greenhouse Road in Cypress, 77433.

These meetings have been declared to be special meetings of Harris County Commissioners Court so that members of Commissioners Court may attend and participate.

The purpose of each meeting is to describe some of the projects proposed for the anticipated 2018 flood bond election and to solicit residents’ input on which projects should be included.

For a comprehensive description of the types of projects the county intends to fund, as well as further information about meetings, a map of projects, and how to comment, visit the flood control district’s webpage.

Meetings are also listed on Save Buffalo Bayou’s Calendar of Events.

Are Costly Flood Basins Proposed Where Natural Basins Already Exist on Buffalo Bayou?

Swales Holding Overflow May Be Natural Remnants of Bayou’s Original Meanders

Numerous Large Trees Cut Along Bayou Banks

June 19, 2018

Went for a stroll in the late morning heat a week ago Saturday along the south bank of Buffalo Bayou in Terry Hershey Park in west Houston. Started out on the pedestrian bridge at Eldridge Parkway and walked mostly but not always in the shade downstream. This is the area where the Harris County Flood Control District plans to remove trees and build the first of three linear detention basins at the edge of the stream to hold overflow from it.

The surprising find was that a significant amount of natural floodwater detention in the form of deep swales or depressions and levees already exists in this wooded area alongside the bayou.

These trees and bushes are growing in an apparently natural swale serving as detention on the south bank of Buffalo Bayou in Terry Hershey Park. Photo June 9, 2018

Disturbingly, we also found that numerous large trees, sycamores and oaks, on both sides of the bayou recently had been pointlessly cut down, likely by Flood Control employees or by contractors clearing woody debris from the channel. Flood Control pays maintenance contractors by the weight of the wood they collect. Trees on the banks are important for protecting against erosion and cooling the stream, as well as absorbing water, among other important functions.

The Natural Path of the Bayou

The swales and depressions, filled with trees and bushes, may correspond to the original path of the bayou, once a meandering wooded stream through this 6.2-mile long linear park. In the late 1940s, in conjunction with construction of the two federal dams, Addicks and Barker, immediately upstream, the US Army Corps of Engineers razed the forest and dug a straight, artificial channel for the bayou, a costly, environmentally-destructive practice long ago abandoned because it increases flooding, among other problems.

The Bat Trip

Happy Hour with Bats

June 13, 2018

Float with geologist, river guide, and Save Buffalo Bayou board member Tom Helm on a relaxing sunset trip to watch the hundreds of thousands of Mexican free-tailed bats emerging from under the Waugh Bridge on Buffalo Bayou to catch their evening meal while evading the high-flying avian predators hoping to make a meal of them. The Bat Paddle is one of Helm’s most popular float trips. Meet about an hour before sunset for an easy paddle upstream from downtown to the bridge. Park the canoes on the beach and enjoy some locally brewed beverages. Enjoy the Houston skyline in the moonlight.  Trip lasts for three hours. All skill levels welcome. Cost is $50 per person. For more information, contact Tom Helm.

  • Another tree cut on the south bank of Buffalo Bayou owned by the River Oaks Country Club, which apparently dumped concrete debris onto the bank in an effort to protect against erosion. Trees and their roots, including fallen trees, protect banks against erosion.
  • Stump of a sycamore, barely visible on left, recently cut among a group of sycamores on the bayou bank in Memorial Park.
  • Close up of the sycamore cut down on the bank in Memorial Park.
  • More stumps of trees cut down on the south bank of Buffalo Bayou. These trees, surrounded by concrete debris apparently dumped on the bank for protection against erosion, would have helped protect against erosion.
  • Upright tree on north bank of Buffalo Bayou in Memorial Park recently cut by maintenance contractor for Harris County Flood Control District.
  • More upright trees chopped by maintenance contractors on the south bank of Buffalo Bayou.

Flood Control’s Destructive Bayou Maintenance Will Lead to More Erosion, More Maintenance

Practices Fall Behind Standards Elsewhere

June 3, 2018

For months we have been receiving complaints about the damage the Harris County Flood Control District is doing to Buffalo Bayou.

Citizens have been sending us video and photographs of contract workers dredging, banging, mucking, bulldozing, slamming and damming the channel and banks; dragging, cutting, and removing large trees, live trees, trees fallen against the banks, trees fallen in the woods.

And now we have reports that they’ve done the same to Cypress Creek in northern Harris County.

The “maintenance” they have done – virtually clearing out the channel and banks — will lead to greater erosion and instability, more sediment and more flooding. And more costly maintenance.

Harvey and the flooding that followed left a huge amount of woody and other sorts of debris in our bayous, our natural drainage system. Buffalo Bayou, our main river, flows from its source in the Katy Prairie for some 53 miles east through the center of Houston, becoming the Houston Ship Channel and emptying into Galveston Bay. For much of that route, the 18,000-year-old bayou remains one of the few relatively natural streams in the city. It accumulated a lot of debris, logjams and snags during Harvey, as did Cypress Creek.

The Importance of Fallen Trees

There are trees along Buffalo Bayou, great tall trees in places, and they sometimes fall into it. Trees have been doing this on rivers for over a hundred million years. Trees, before and after they fall, are a crucial part of the river’s natural system. Overhanging trees shade the water, regulating the temperature. Their extensive roots, together with the roots of riparian plants, anchor the bank, protecting the bank from washing out. When trees fall into the channel, they continue to provide stability to the stream and its banks, trapping sediment, fortifying against and deflecting heavy flows, helping the channel to maintain a healthy width and depth and to form riffles and pools, helping the stream to restore itself more quickly after a flood, and providing food and habitat for the diversity of creatures large and small that sustain the bayou’s ecosystem.
