Buffalo Bayou Doesn’t Like Sidewalks, It Seems

Buffalo Bayou Park Was Supposed to Be More Stable

Update: “Endless Repairs: Buffalo Bayou Sets Its Own Terms,” Houston Chronicle, Nov. 20, 2019

Well, we can’t help but wonder if constantly scraping and repairing the sidewalks, forever reinforcing the collapsing banks somehow, and repeatedly replacing the trees and landscaping is fully covered by the $2 million annual maintenance budget for Buffalo Bayou Park paid by Houston city taxpayers.

The popular, much praised, and much needed park on the banks of the bayou between Allen Parkway and Memorial Drive is suffering from some serious erosion problems. And that matters to us not just because of the expense and waste. This $53.5 million project, a boon to adjacent property owners and those who live and work nearby, was touted as a successful example of what the Harris County Flood Control District, egged on by the Bayou Preservation Association, wants to do to our healthy, historic wild bayou further upstream in and around Memorial Park. Buffalo Bayou Park was supposed to be more stable! The flood control district calls it Natural Stable Channel Design, but it always looked to us like they were doing everything you’re not supposed to do on the banks of streams: dig up the banks, run heavy equipment over the banks, remove the trees and vegetation (yes, they did a lot of that), build concrete and asphalt sidewalks on the banks, plant grass and mow it.

Let’s Work With Nature, Not Against It

Once you’ve done all that, and the banks and channel start falling apart, it’s pretty difficult to fix it. Best to let the bayou do what it will do anyway. (And eventually the bayou will rebuild and replant it all.) But it seems unlikely that the City and the Buffalo Bayou Partnership are going to sit back and patiently let millions of dollars worth of sidewalks, lamps, and bridges collapse into the bayou. Can they stop it? Time will tell.

In the meantime, it does make one wonder about all those concrete trails they are carving out of the banks and floodplains of the bayous for the Bayou Greenways project. A nice idea, but is that going to work?

Here’s what we’re talking about. What this slide show of photos of Buffalo Bayou Park between Shepherd and Montrose taken on Nov. 15, 2015 (and updated with later photos).

Film: Letting the River Heal

Learning to Respect A River’s Natural Process

October 18, 2015

“We have to be patient,” says Steve Nelle, Natural Resources Conservation Service, retired.

“Nature’s going to recover that area at her own timetable in her own way. It’s best to accommodate that natural process.”

Watch this moving and informative 14-minute documentary about a river’s natural process and Best Management Practices for protecting against erosion and preserving a river’s important role in cleansing our water, slowing storm water and runoff, and providing wildlife habitat.

All of this applies to Buffalo Bayou as well as our other bayous, creeks, and streams in Harris County. Even a small riparian buffer of native trees and vegetation a few feet wide is important for our waterways and the cleanliness of the water flowing through our neighborhood streams and into our bays and oceans. But on Buffalo Bayou, especially as it flows past Memorial Park, we are fortunate to have room for the river to move. Letting the river be a river is the most current scientific thinking on river management, even in cities. A dynamic river creates the most beneficial and biologically diverse environment.

Let’s work with nature, not against it.

This lovely, short film was made about the Blanco River and the impact of the 2015 Memorial Day flood on Wimberly, Texas. We can all learn from it.

Watch the film.

Float In The Air Down Buffalo Bayou With Houston Photographer Jim Olive

October 17, 2015

Travel down the remarkable historic stretch of our 18,000-year-old bayou proposed for “restoration” by the Harris County Flood Control District and the City of Houston. The $6 million project, violating virtually every Best Management Practice for riparian areas, would pointlessly destroy and rebuild over 1.25 miles of a naturally-functioning bayou as it flows past Memorial Park and the Hogg Bird Sanctuary on the north and the River Oaks Country Club on the south.

Photos taken on October 2, 2015. Thank you, Jim Olive!

  • This massive new drainage outfall on Buffalo Bayou at Woodway, soon to be once-again a public boat launch, is not in the project area targeted for "restoration" by the proposed $6 million Harris County Flood Control project. But this formerly forested area in Memorial Park, destroyed for a $1.3 million City "erosion control" project, is for many the beginning of a float trip through the threatened historic natural area in the park. Photo by Jim Olive, Oct. 2, 2015
  • The same drainage outfall/boat launch in Memorial Park at Woodway one year later after an "accidental" mowing of riparian plants by a Memorial Park maintenance crew and now, apparently, bulldozing of what remained for some reason. Photo by Jim Olive on Sept. 29, 2016
  • Concrete riprap placed by the River Oaks Country Club in August 2015 on a terrace below the high bank and adjacent to a wetland at the beginning of the proposed $6 million Harris County Flood Control project. The young box elder and other vegetation naturally planted there by the bayou were destroyed by soil-damaging heavy equipment. The mowed golf course extending to the edge of the high bank and the concrete path for motorized golf carts likely contributed to erosion of the high bank. Memorial Park on the left.

  • Aerial view of a lovely meander in Memorial Park showing very old high bluffs on the right. The meander would be filled and the high bluffs leveled by the proposed Memorial Park Demonstration Project. Jim Olive photo, Oct. 2, 2015

  • Brush on the banks taken down by the Memorial Day 2015 Flood is collecting sediment and naturally rebuilding the banks. The project proposed by Flood Control mimics this natural bank stabilizing process but would pointlessly spend millions of public dollars to destroy the superior work of nature and replace it with costly engineering likely to fail.

  • Aerial view of the tributary and high banks of the Hogg Bird Sanctuary on the north, a public park, and the River Oaks Country Club golf course on the south near the downstream limit of the area targeted for dredging, grading, and filling by the Harris County Flood Control District. The high bank in the sanctuary slumped during the spring high waters, but the brush lying there is collecting sediment and naturally rebuilding the bank. Photo by Jim Olive on Oct. 2, 2015

Update on Puzzling Project to Bulldoze Wild Buffalo Bayou

Damaging, Expensive, Contradictory Plan Still Threatens

Conflicts Still Apparent, Purpose Still Unclear

No Permit Yet

October 8, 2015

The Harris County Flood Control District has responded to largely critical public comments to the Army Corps of Engineers about Flood Control’s misguided project to destroy one of the last natural stretches of Buffalo Bayou in Houston, a most remarkable asset to have in the middle of a city. The Corps is reviewing the Flood Control District’s responses, says Jayson Hudson, who has been the Corps’ Galveston District project manager for the permit application.

Flood Control must apply for a permit from the Corps of Engineers because the Clean Water Act requires the Corps to ensure that projects on federal waters do not damage the health of our waters. Federal waters are defined as navigable streams (Buffalo Bayou) up to the Ordinary High Water Mark, their tributaries and adjacent wetlands, all of which form the great living veins and arteries of our limited water supply. Some studies argue that all riparian areas , the highly biologically diverse natural gardens and forests along stream banks so vital for clean water, should be considered protected wetlands .

This beautiful meander, a natural detention area, would be filled in and graded, the woods and high cliffs destroyed, and the entire floodplain area obliterated by a permanent road. Aerial photo on Oct. 3, 2015, by Jim Olive
