Wasting Money the Old-Fashioned Way
Costly Bayou Repairs Do More Harm Than Good, Won’t Last
Nov. 21, 2016
Updated April 23, 2017 — The Harris County Flood Control District reports that repair costs through March 2017 are $1.25 million. Terry Hershey Park remains closed until construction work is complete.

From a distance you could hear the monstrous roar of the heavy equipment in the woods. Following deep, wide tracks smashed into the bare dirt along the bank of Buffalo Bayou, passing large cottonwoods apparently cut to make way for the big equipment, we came across a scene of troubling destruction.
A gigantic articulated 30-ton dump truck with six massive wheels was slowly rolling towards us with a large load of fresh dirt and dripping mud dug up from the bayou bank. Further along a 60-ton excavator on tracks sat on the very edge of the bank, expertly swiveling back and forth, scraping up the dirt bank and dumping it into the truck, scooping up loads of white limestone rock and dropping it in a layer where the excavated bank once was.
We’d seen the eroded bank before the “repairs” began. This damage was far worse.
It didn’t have to be this way.
A Giant Falls
June 14, 2016
We have been watching this magnificent cottonwood on the south bank of Buffalo Bayou in Buffalo Bayou Park. Beginning in 2012 the Harris County Flood Control District realigned the banks and removed a lot of trees and stabilizing vegetation from the banks of the bayou between Sabine and Shepherd streets for its “natural stable channel design” improvements in the park.
Those “channel conveyance” alterations left many of the few remaining large trees on the weakened banks in a vulnerable state. In the Fall of 2015 part of this grand old tree broke apart.
And now, finally, sadly, the great tree has fallen. Others will go eventually.
Big trees fall into the bayou all the time. It’s part of the natural process, and fallen trees collect sediment for bank building, provide fish and wildlife habitat, and slow storm waters. But trees, whose massive roots help hold the bank together, are not supposed to fall in the water because in the name of progress we dug up and destroyed the structure of the surrounding banks, breaking up the intricate root systems of the vegetation that had been there for a very long time.
Still, we have had unusually high rainfall and stream flow in our bayous. The banks in many places are now lush with new green growth and wildflowers. For nearly two months we have had record high flows in Buffalo Bayou as the Army Corps of Engineers attempts to empty the flood control reservoirs behind Barker and Addicks dams in western Harris County. We have reports of trees downed all along the bayou.
Watch this slideshow of the great cottonwood as it maintained its lonely vigil until the end.
