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.

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.

Can An Urban Stream Restore Itself?

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

June 15, 2016

Updated with August 2016, April 29 and July 11, 2017, photos of self-repaired Hogg Bluff

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.

Radio Talk about Natural Flood Control

Flooding on the Air

June 14, 2016

Susan Chadwick, executive director of Save Buffalo Bayou, and John Jacob, board chair of Galveston Baykeeper, wetlands expert, and director of the Texas Coastal Watershed Program at Texas A&M, were on the radio today talking about bayous, streams, wetlands, floodplains, and natural solutions to flooding. The popular weekly Tuesday program, Eco-Ology, hosted by Pat Greer and H.C. Clark, aired from 3 to 4 p.m. on KPFT 90.1.

Among other things, we talked about proposals from the city and from the county and others to buyout property owners and widen and enlarge our bayous, creeks, and streams to handle increasing rains. This prospect might be alarming to those of us who recognize the importance of trees and vegetation along our waterways — for erosion control, cleansing our water, removing pollutants, slowing runoff, providing wildlife habitat, and many other life-sustaining functions, not to mention social benefits like we need nature to be sane.

But what if they didn’t bulldoze our waterways and widen them artificially? What if they removed the built structures and created parks and allowed room for our rivers and streams to move and adjust on their own by letting them flood into their natural floodplain?

This is in fact the latest thinking in flood control worldwide. Room for the river to move. Even in the Netherlands they are tearing down their big gates and dikes, letting the water in while raising the land where people live and work. Even in Missouri.

A lot cheaper, more cost effective, and more beneficial overall.

Listen to the Eco-Ology program on KPFT 90.1.

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.

Proposed Roads to Damage Katy Prairie Preserve

Urgent Notice of Public Meeting and Comment Deadline

May 1, 2016

Updated May 3, 2016

The Katy Prairie Conservancy has announced that the Harris County Engineering Department has corrected the email link for commenting on proposed changes to the Harris County Major Thoroughfare and Freeway Plan that will damage the Katy Prairie.

The correct email address is:

us290amtstudy@hcpid.org

Update May 8, 2016

The comment period has been extended until May 13.

The Katy Prairie Conservancy has sent out an urgent notice of a Harris County plan to build new roads in and around the Katy Prairie Preserve. The preserve is a nonprofit land trust project to restore and protect historic wetland prairie in Waller and western Harris counties.

Buffalo Bayou originates in the Katy Prairie. Prairie wetlands, rapidly being destroyed and paved over by development, are vital for clean water and flooding mitigation, as are forested riparian zones along the banks of streams such as Buffalo Bayou and its tributaries.

When, Where, and How

The Harris County Engineering Department is holding a public meeting Monday, May 2, 2016, on proposed changes to the Major Thoroughfare and Freeway Plan (see particularly pages 25 through 29) that will “degrade the Katy Prairie Preserve System,” according to the conservancy.

The meeting takes place from 5:30 to7:00 pm at the Hockley Community Center, 28515 Old Washington Road, in Hockley, Texas.

The conservancy urges that if you cannot attend the meeting, please submit your comments in writing by May 13, 2016, via email to us290amstudy@hcpid.org or by mail to:

Harris County Engineering Department

10555 Northwest Freeway, Suite 120

Houston, Texas 77092

Attn: Fred Mathis, P.E.

Key Talking Points

The conservancy says that while Harris County is proposing to dispense with parts of the one-mile road grid through some of the preserves, the county also recommends constructing new roads in sensitive and/or inappropriate areas.

Here are some of the conservancy’s main objections:

  • In general, the plan does not effectively take into consideration the importance of the Katy Prairie preserves in reducing flooding, improving water quality, providing wildlife habitat, and offering recreational opportunities for the residents of the Greater Houston area. Roads should go around the Katy Prairie preserves and not through them. Roads can move, nature cannot.
  • KPC does not support the new proposed east-west road through the upper third of the Warren Ranch; it will cause fragmentation and impair ranch operations.
  • KPC does not support the new proposed north-south road through the conservation easement lands owned by KPC’s conservation easement donors; this land provides sensitive habitat and flood protection as well as other environmental benefits. It should be protected.
  • A number of the proposed new roads, if built, would be under water during flood events if the most recent flood event is any indication of where floodwaters go on the prairie.

A Roundup of Opinion on What Happened and Why

Houston neighborhoods shouldn’t be detention ponds

Commercial developers are dumping their runoff into our homes

By Bruce Nichols for the Houston Chronicle

April 19, 2016

Houston has a lot of great characteristics. It is open to new people, new ideas. It encourages entrepreneurs. Its energy-based economy is strong, despite the slowdown. But one big flaw is our failure to organize local government to protect homeowner investments, a big share of life savings for most of us.

The latest example of what this flaw leads to: Hundreds of homes flooded April 18. It was not a one-off event, a freak of Nature, as we have been assured. It will happen again, to more people, as more and more land is paved over without developers’ controlling their excess runoff.

Don’t blame Mother Nature for flooding. Blame City Council.

The disasters are predictable. Why aren’t we preventing them?

By Cynthia Hand Neely and Ed Browne, Residents Against Flooding, for the Houston Chronicle

April 19, 2016

Man-made, preventable flooding has surged dirty, sewage-ridden water through Houston living rooms three times now in seven years, yet city government fails to prevent these recurring emergencies.

Really? If losing homes, livelihoods, retirement savings, health and sanity (and at least one life) aren’t reasons enough to make emergency detention and drainage improvements, what in the world does it take?

Right now, too many real-estate developments do not detain storm water run-off from their new construction, and instead allow it to flow downstream into other neighborhoods, into people’s homes. This new development is responsible for unnecessary flooding of neighborhoods that previously weren’t flood plains, weren’t prone to flooding. That new development is also responsible for flood insurance rising 100 to 200 percent (before the Tax Day flood) in these non-flood plains.

City government is allowing this to happen. Developers use loopholes and grandfathering to avoid doing what the city’s laws require them to do. Is it ethical to allow a new office building to flood an entire neighborhood even if a loophole makes it legal?

Disaster by design: Houston can’t keep developing this way

We can’t stop growing. But to avoid flooding, we’ve got to be smarter about it.

By John S. Jacob for the Houston Chronicle

April 20, 2016

Let’s review the facts before this teachable moment fades away.

We live on a very flat coastal plain — much of it only a four-foot drop over a mile. And much of it with very clayey, slow-to-drain soils.  We also live in the region of highest-intensity rainfall in the continental U.S. So it is going to flood. Mother Nature will continue to deliver floods no matter what we do. Don’t count her out.

Flooding does not occur uniformly across the region. There are floodplains, and areas near the floodplains. There are low areas and there are higher areas. We need to know where these are. Obviously! — and yet we don’t seem to know.

But humans have screwed things up royally.

Wrecked wetlands lead to flooding. Here’s what you can do.

By Jennifer Lorenz for the Houston Chronicle

April 20, 2016

For the past twenty years, we at Bayou Land Conservancy have watched, horrified, as the Houston region’s wetlands are scraped and filled in — directly resulting in increased flooding.

When wetlands are allowed to function, they’re the kidneys of the area’s watershed. Their special soil types are surrounded by particular wetland plants that help hold water in shallow depressions. They clean the water as they allow some of it to filter slowly into the ground, the rest to drain slowly into our bayous. That process is the foundation of our region’s ecology.

The rampant destruction of our forested and prairie wetlands is upsetting this balance, drastically reducing the land’s ability to absorb water. By allowing so many wetlands to be turned into subdivisions, we’re not just kicking them to the curb; we’re turning them into curbs. We need the ecological equivalent of dialysis.

How policy fills Houston living rooms with water

We know how to lessen flood damage. But will we take the steps?

By David Crossley for the Houston Chronicle

April 21, 2016

The flooding of April 18, 2016, was a profound experience for many reasons. The electrifying videos from drones, so quickly and easily available on Facebook, and hours of television enterprise brought us the clearest picture we’ve ever had of the immensity and the tragedy of flooding in Houston, and another reminder that all neighborhoods are not equal.

It was a spooky and historic picture; that was the most one-day rain in Houston’s history.

Extreme rain events like this are going to be more common as we slide further into climate change. Are we doing things to ease the slide or are we making it worse?

Greenspoint, poverty and flooding

Would low-income families be better or worse off if flood-prone apartments were razed?

By Susan Rogers for the Houston Chronicle

April 22, 2016

Floods, like any natural disaster, are great levelers. All of those affected suffer equally. It is in the wake of a great loss that the disparity emerges. For some, it can be easy to find the resources to rent a new apartment, to move, to turn on your utilities — or at least not extremely hard. For others, those financial challenges are overwhelming.

That division shows sharply in Greenspoint, where some of this week’s worst flooding occurred.

The mall, office towers, multi-family apartment complexes, and strip retail development are disconnected and isolated from each other both physically and demographically. Fundamentally there are two communities: one community that caters to the area’s office workers, and one community for those who call the area home. The stores and restaurants that line Greens Road and Greenspoint Drive, which cater to office workers, are closed during the evenings and on weekends, when the area’s residents would be more likely to shop.

Buffalo Bayou Doesn’t Like Sidewalks, It Seems

Buffalo Bayou Park Was Supposed to Be More Stable

Nov. 16, 2015

Updated Nov. 17, 2015

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).
