Reminder: Buffalo Bayou Watershed Flood Bond Meeting July 30

Also Barker Reservoir Meeting on Aug. 1

 

July 23, 2018

The Harris County Flood Control District and members of county commissioners’ court continue to hold meetings around the county to present proposals for projects attempting to reduce the hazard of flooding.

The meeting about projects proposed in the Buffalo Bayou watershed will be held on Monday, July 30, from 6 to 8 p.m. at the Memorial Drive United Methodist Church, 12955 Memorial Drive in Houston. A meeting to present projects proposed for the Barker Reservoir watershed is scheduled for Wednesday, Aug. 1, from 6 to 8 p.m. at Memorial Parkway Junior High, 21203 Highland Knolls Drive in Katy. Buffalo Bayou flows from its headwaters near Katy into and through Barker Dam.

The projects are to be funded with the proceeds of a $2.5 billion bond issue should the voters approve on August 25. The bonds would be issued over a period of ten to fifteen years, according to the flood control district, and repaid through a property tax increase of no more than two-three cents per $100 of home valuation. Homeowners with an over-65 or disabled exemption and a home worth $200,000 or less would not pay any additional taxes, according to the district.

Most of the projects proposed are projects that had long been planned. For instance, a controversial project to remove forest and excavate basins to capture and temporarily hold overflow on the south bank of Buffalo Bayou in Terry Hershey Park is listed with a $10 million cost estimate. The project in its initial stages would allegedly create 60-100 acre-feet of temporary storage alongside the bayou. The linear detention, siphoning flow out of the bayou, is planned to compensate for eventual additional City of Houston drainage into the bayou from neighborhood streets.

Barker and Addicks dams both drain into Buffalo Bayou, and overflow from Cypress Creek on the rapidly developing Katy Prairie in northwest Harris County also drains into the overburdened Addicks Reservoir, adding to the pressure of runoff into Addicks and the bayou.

Other than the Hershey Park detention project, some $21 million is slated for a new detention basin north of John Paul’s Landing on Upper Langham Creek, which drains into Addicks.

However, most of the projects listed for these watersheds mainly focus on repairing channels and improving conveyance – making more stormwater flow faster into and through the reservoirs. This has the potential to cause more problems and more flooding. Modern practice elsewhere is to focus on slowing the flow, making room for the river with wider floodplains. We would hope for more money to be spent on land aquisition, buyouts in floodplains, preservation of undeveloped land, forest, wetlands, prairies, and riparian vegetaton; creation of green space, restoring meanders, and programs to encourage slowing of rain runoff beginning with individuals and neighborhoods.

There are also funds proposed to be used in collaboration with Army Corps of Engineers, which owns and operates Addicks and Barker, to evaluate the effectiveness and operation of those 70-year-old dams.

A complete list of projects can be found on the flood control district’s website. The website also offers a way to make comments about the projects.

The meetings are not set up for the public to engage officials or voice opinions. They are informative only – with numerous stations staffed by flood control personnel to explain projects. However, paper and pencils are provided for citizens to write comments.

Engineers Caused the Flood That Led to Creation of Flood Control District

A Fact-Based Response to “Engineers’ View” in the Texas Tribune

March 6, 2017

A few weeks ago the Texas Tribune published an editorial comment written by engineers Michael Bloom and Steve Stagner responding to the excellent investigative work on flooding in the Houston region, “Boomtown, Floodtown,” published by the Tribune and ProPublica on Dec. 7, 2016. See our summary of the report here.

In their TribTalk editorial “Boomtown, Floodtown Reconsidered, An Engineer’s View,” Feb. 6, 2017, Bloom and Stagner repeat a couple of erroneous statements commonly used by representatives of the Harris County Flood Control District in support of the district’s shaky position that paving over the prairie, i.e. development, is not contributing to flooding.

According to this point of view, our native tallgrass prairie and its associated wetlands are hardly better than concrete when it comes to slowing and absorbing rainwater. These deep-rooted grassland prairies, with water-absorbing root systems that can reach 12-15 feet into the ground or more, once existed around and upstream of Buffalo Bayou, in Katy, west of Houston, for instance, source of Buffalo Bayou, as well as up and down the coastal plain. Practical people are trying to preserve and restore what remains.

In support of their argument, Bloom and Stagner summon up a point commonly made by members of the local engineering community: that the 1935 flood on Buffalo Bayou that devastated downtown Houston and led to the creation of the Harris County Flood Control District happened even though the Katy Prairie way upstream was then a big natural tallgrass prairie.

This argument is wrong on two points. Read why in this fact-based response by Save Buffalo Bayou to an “Engineers’ View” published as a comment in the Tribune’s TribTalk.

Petition to End Avoidable Flooding

Citizens Call for Regional Oversight Based on Science, Transparency, and Enforcement

Jan. 17, 2017

A Houston group called Citizens Solutions to Flooding is circulating a petition calling for the creation of a long-overdue Houston-Galveston regional body to ensure that new construction and development does not increase flooding.

The petition focuses on the inadequacy and lack of enforcement of current regulations regarding stormwater drainage and detention. It calls for transparency in the permitting process and financial incentives for property owners to retrofit properties to conform to more effective standards for controlling stormwater running off impervious surface.

Houston’s natural tendency to flood has been greatly worsened by uncontrolled development and the proliferation of hard surface like parking lots, building rooftops, and roadways that rapidly collect and concentrate rainwater rather than slowing, absorbing, and dispersing it.

In calling for regional oversight, the petition notes that “watersheds know no county boundaries.” And development in one watershed can worsen flooding in another watershed.

Notably, the petition does not call for widening and deepening our bayous and streams, an outmoded, costly, ineffective, and environmentally damaging solution preferred by city and county engineers. More green space, not less, is the consensus of leading experts, including Phil Bedient, director of the SSPEED storm center at Rice University.

Science vs Engineers

Flood Control District and Scientific Experts In Opposite Corners

“You need to find some better experts.” — Former Harris County Flood Control District Director Mike Talbott to reporters for the Texas Tribune

Dec. 9, 2016

Excellent reporting from the Texas Tribune and PropPublica on the battle over what causes flooding in the Houston area and what to do about it.  The Houston Press has also published an informative follow-up interview with the current director of the Flood Control District, Russ Poppe, after the recent retirement of Talbott.

Some excerpts:

Scientists say the fundamental problem is that Houstonians have assumed they can simply engineer their way out of flooding.

They can’t. And widening and deepening our bayous and streams is the wrong answer. We need to understand and work with nature. It’s cheaper, more effective, and better for us. Storm water needs to be absorbed, slowed down, and spread out before it reaches our streams.

Houston-area officials could work to preserve green space; strengthen regulation on development; plan for a changing climate; and work harder to remove the 140,000 homes that remain in the 100-year floodplain. …

As wetlands have been lost, the amount of impervious surface in Harris County increased by 25 percent from 1996 to 2011, [Sam] Brody [of Texas A&M Galveston] said. And there’s no way that engineering projects or flood control regulations have made up for that change, he said.

Between 2001 and 2005, his research found, the loss of flood-absorbing land along the Gulf of Mexico increased property damage from floods by about $6 million — much of that outside floodplains.

“There’s no doubt that the development … that we’re putting in these flood-prone areas is exacerbating flooding over time,” Brody said. “There’s a huge body of research out there beyond Houston, across the world” supporting that argument.

Research by [then Director Mike] Talbott’s own Harris County Flood Control District points to the effectiveness of prairie grass to absorb floodwater. ‘The restoration of one acre of prairie,’ a 2015 report by the district wrote, would offset the extra volume of runoff created by two acres of single-family homes or one acre of commercial property. (The district says that data is preliminary.)

But Talbott and his successor, Russ Poppe, don’t buy the research.

Commissioner Radack Responds

“Buffalo Bayou Not a Natural River”

Supporting Costly Engineering to Slow the Flooding River. Spending Money to Stop the River Slowing For Free.

Nov. 30, 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.

Harris County Precinct Three Commissioner Steve Radack called to comment on our article criticizing unnecessarily costly and destructive “repairs” to the north bank of Buffalo Bayou in Terry Hershey Park. The six-mile long park is in Precinct Three in far west Houston and Commissioner Radack is the boss there.

Radack’s main point, apparently in support of needlessly spending an excessive amount of money, was that Buffalo Bayou is not a natural river. Because the bayou is not natural, it “does not naturally meander.”

For background: the naturally meandering bayou in Terry Hershey Park was stripped and straightened in the 1940s and ‘50s. Last spring high waters from record rains and extended high flows from the federal dams immediately upstream ate away at the bank in places and damaged the asphalt hike-and-bike trail on the north side. We pointed out that this had occurred where the old meanders or bends were. The bayou, we said, was seeking out its historic meanders, adjusting to the flow.

Our point was that it would make more sense, in accordance with the most advanced river management practices across the country and around the world, to move the asphalt trail slightly away from the very edge of the water and allow the river room to move and restore itself. This would be far cheaper, prettier and more natural, and healthier for the bayou, the beneficial trees and plants and creatures that grow there, and for the water flowing through it to the bay. Doing that rather than hardening the bank in an artificial straight line is also less likely to cause flooding and erosion downstream and less likely to require expensive repairs all over again. It’s also federal policy.

But according to Radack, this doesn’t matter, because Buffalo Bayou is not natural. It’s not natural  because the Corps of Engineers “controls the flow.” The bayou “only has water in it,” Radack explained patiently, if the Corps opens the floodgates. “The water comes from the reservoir system.”

Therefore, according to Radack, the bayou is “not natural.”

Is that all true? Beg pardon, but no.

But here’s a puzzle: Radack supports spending tens of millions in public funds to carve up the banks and engineer some two dozen in-channel detention basins on the bayou in Terry Hershey Park. (See below.) But he opposes allowing the bayou to carve out for free its own detention by widening and restoring its old bends. Instead he approves spending taxpayer funds to keep the bayou from doing that.

Does that make sense? Seems contradictory to us.

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.

See also “Commissioner Radack Responds.”

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.

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.

County Commissioner Provokes Wrath of Flood Victims

Aug. 8, 2016

Updated Aug. 9. Radack Doubles Down, Stands His Ground. Read Here.

Harris County Precinct 3 Commissioner Steve Radack has unleashed a flood of outrage by telling an audience of several hundred citizens in an area of the city heavily damaged by flooding that “some people enjoy flooding.”

The large audience at a meeting of the Cypress Coalition Thursday, Aug. 4, gasped and groaned when Radack took the podium, waved his hands, and said that “some people frankly over the years, in the years I’ve been doing this, that frankly enjoy floods about every seven years, because they want new cars, they want their homes redone.”

Only Rain Causes Flooding!

Cynthia Neely, board member of Residents Against Flooding (RAF), was at the meeting at the Metropolitan Baptist Church with RAF Chair Ed Browne. She reports that both Radack, who’s been in office for 27 years, and Mike Talbott, retiring director of the Harris County Flood Control District, blamed Mother Nature for flooding.

The Flood Czar Answers His Own Phone

But What Causes Urban Flooding?

July 12, 2016

Steve Costello explained for probably the hundredth time or more that he is not really the flood czar of Houston but the chief resilience officer.

The soft-spoken Costello, a civil engineer, former member of the Houston City Council (serving six years), former president and current board member of the Memorial Park Conservancy, and former candidate for mayor of Houston, was speaking at a meeting of the Briar Forest Super Neighborhood in west Houston a few weeks ago. Buffalo Bayou runs through the Briar Forest Super Neighborhood.

Appointed by Mayor Sylvester Turner in early May, Costello has been making the rounds, speaking at public meetings, attending others, such as the highly emotional town hall meeting with US Rep. John Culberson in June. Costello also has been giving interviews. Recently he flew off to Washington D.C. with the mayor and members of the Houston City Council to meet with officials of the Army Corps of Engineers about a multi-billion dollar plan to dredge and deepen Lake Houston in order to enlarge its capacity and alleviate flooding in northeast Harris County. Lake Houston is a major source of Houston’s drinking water.

But back in late June he was explaining to the Briar Forest crowd of about twenty-five neighborhood activists that while his sole mission was to do something about flooding, and his wife liked the idea of being a czarina, really he was the chief resilience officer. The concept, he explained, was a response to the Rockefeller Foundation’s 100 Resilient Cities project. Mayor Annise Parker had applied to the program for funding and support for a resilience officer, who would have focused not just on flooding but also on broader social issues like unemployment and transportation. Mayor Turner decided he wanted to focus on drainage and flooding, and the Rockefeller Foundation decided not to fund a position for Houston, said Costello.

No Staff and No Budget

As a result, Costello answers his own phone and emails himself. He has no staff. Apparently he has no funds or budget. (He also said in a later email exchange that he wasn’t sure where the funds for his salary were coming from and didn’t answer how much he was being paid.) Yet he has been bravely handing out his card, offering his cell phone number and email to myriad people in a city drowning in outrage and misery over increasing and repeated flooding, lost homes, cars, property, savings, and lives.
