Late Winter on the Bayou

Plus Houston Stronger Survey, Scenic Houston Panel Discussion About Buffalo Bayou, Flood Planning Vacancies, Resiliency, and More

March 7, 2021

Our famous photographer Jim Olive was back in town, so a few days ago we went out into the woods in the drizzle just after dawn to photograph that bend in the bayou in late winter for our years-long series documenting the same bend through the seasons. The backup photographer, fearing that winter would soon be over despite the record freeze, had taken a sunny interim photo, which received some criticism from the master. (“Too flat,” he said.)

But now we were standing in a parking lot off the Picnic Lane/Loop in Memorial Park in the middle of Houston staring at sawed-up pieces of a big, old oak tree, new wooden fencing reinforced with moss-covered oak limbs, and a pile of sawdust.

Apparently it is a priority of the Memorial Park Conservancy to keep people off these lovely trails. In addition to a new wooden fence, there was extensive wire fencing winding along the edge of the tangled woods.

We found a way in, noting the tiny buds of green in the trees. Jim set up his borrowed tripod, and we waited for just the right light in the fog.

Conservancy Plans to Bulldoze, Smother the Bank

We couldn’t help but notice a couple of the conservancy’s Keep Out signs someone had tossed down the bank. The photographer’s helper wandered downstream a bit, contemplating the slumped, eroded bank, the colors of the revealed earth, the powerful forces that shaped the irregular mounds and valleys of the downward sloping bank. This was an area damaged by the Harris County Flood Control District when it removed the stabilizing woody debris, scraped and mucked around in the channel with an excavator and barge during its “maintenance” operations after Harvey.

Studying the slump brought back poignant memories of playing on the wild sandy bank of the bayou as a child in Houston, of being in awe of the force of nature, that early sense of the bayou as a living thing. It was a rare learning experience to have, and a privilege.

These memories were prompted by the sad news that the conservancy is planning to bulldoze and “restore,” smothering and landscaping the public banks of the bayou in the Old Archery Range, a small section of the park west of the 610 Loop off Woodway Drive.

We’ll have more on that soon. But as a historical note, an earlier, far more enlightened and ecologically sensitive master plan for Memorial Park in 2004 (the current plan dates from 2014-15) said that “the recommended course of action for the Bayou is simply to leave it alone and consider it a symbol of dynamic natural process. The Bayou can serve as a valuable environmental education tool that depicts the change inherent in nature. Possible solutions such as concrete surfacing and decreasing the bank slope would only destroy the habitat value and visual amenity of the bayou and conflict with the ability to observe natural process.” (p. 11)

Houston Stronger Survey due Tuesday, March 9

Houston Stronger is a coalition of civic groups and business associations in the Houston region that came together after Harvey in 2017 to advocate for flood and storm resiliency.  A major flood problem during Harvey was too much stormwater flowing too fast into Barker and Addicks reservoirs in west Houston. The normally dry reservoirs drain into Buffalo Bayou.

In response, last October the US Army Corps of Engineers, which owns and operates those flood control dams, announced a tentative proposal to build a new dam and reservoir on Cypress Creek and the Katy Prairie and deepen and widen Buffalo Bayou for some 22 miles from the dams all the way to downtown.

The Corps’ Interim Plan was widely unpopular, and while continuing to gather public input, they are working on the next draft due out in late spring or early summer. In the meantime Houston Stronger has come up with an alternative to the Corps’ proposals. It includes elements of a plan proposed by the Katy Prairie Conservancy, which is part of the Houston Stronger group. Both plans include digging a 23-mile long tunnel, perhaps 40-feet wide, to take stormwater from Addicks and/or Barker dams to the Houston Ship Channel.

Save Buffalo Bayou is opposed to a $4 billion flood tunnel, which has no ancillary public benefit, among other problems, and favors a stronger focus on slowing the flow of stormwater from commercial and residential property into streams that feed into the reservoirs. SBB supports other elements of the Houston Stronger/Katy Prairie plans, including expanding, protecting, and restoring the Katy Prairie.

Houston Stronger is asking for public feedback on its plan, called the Buffalo Bayou Community Plan. So take a look at the plan and answer the eight questions in their brief survey by Tuesday, March 9, if possible.

Here is a link to the Houston Stronger Plan. Here is a link to the survey.

Resilient Houston One-Year Update

The City of Houston has released a one-year update on the progress of its Resilient Houston Plan. The plan, released in February 2020, addressed climate, housing, health, flooding, neighborhoods, parks, and more.

According to a press release from Mayor Sylvester Turner’s office, “56 of 62 prioritized actions (90%) are in progress, five actions (8%) are paused or haven’t started, and one action (2%) is complete.”

Open Positions on Regional Flood Planning Group, Meeting March 11

The San Jacinto Regional Flood Planning Group is looking for two new members.

In April 2020 the Texas Water Development Board set up 15 regional groups to help formulate regional and state flood plans.

The San Jacinto Region 6 includes Harris, Montgomery, Galveston, and parts of Brazoria, Fort Bend, Waller, Grimes, Walker, San Jacinto, Liberty, and Chambers counties.

The two new positions are in the Coastal Communities and Public categories. Nominations are due by March 26.

Here are the current members of San Jacinto Region 6 Flood Planning Group. See also here.

The next meeting of the group is March 11 at 9 a.m.

That Bend in Winter: A Hidden Landscape

Waiting for the Return

Feb. 24, 2021

We are quite a bit late posting a winter photograph for our ongoing series documenting the same bend in Houston’s Buffalo Bayou throughout the seasons. Our devoted and generous photographer Big Jim Olive is living with his beloved in fiery California these days where the air is supposed to be better. But he still frequently returns to his native Texas for photography jobs and visits with his many friends. Founder and executive director of the Christmas Bay Foundation, he also participates with other volunteers in Texas Parks and Wildlife’s annual Abandoned Crab Trap Removal program, which takes place from February 19-28.

Last week he was on his way, driving cross country, stopping to take photos of icy cacti. But by Seguin the frozen, snowy highway was closed, and after two nights in a motel there Jim was forced to turn back, leaving behind the excellent barbecue.

He’s returning this week, despite the forecast for stormy (warm) weather. But in the meantime the backup photographer had already gone out into the forbidden woods of the city’s Memorial Park to document that bend in winter. The fear was that winter would soon be over before Jim returned, despite the historic weather that froze the city and state just a few days earlier, leaving us all in the dark.

Frozen. Still Living. Still Closed. Sighting of a River Otter. Dumping of Picnic Tables

Whether you think a bare winter landscape is lovely is a matter of personal taste. For some people, the sight of seemingly dead trees and plants can be alarming. Will they come back?  But winter, particularly a harsh and deadly winter, however disturbing, does reveal a landscape that would ordinarily be hidden.

On a happy note, we did receive after the freeze a report of multiple sightings of a river otter in the bayou across from the park around Pine Hill. And many have surely noticed the flocks of handsome cedar waxwings in the city flitting from tree to tree, often yaupon, feasting on berries.

The popular trail through the bayou woods on the southeast side of Houston’s Memorial Park was still fenced off and posted with the same fictitious warning signs. In fact, the gates to the Picnic Loop itself were still locked on this sunny, warm Saturday after the horrible freeze. No doubt this was due to a shortage of staff still coping with the disastrous impact of the winter weather. People were forced to park their cars in any spot they could find and squeeze with their kids and bikes and strollers through or around the gates.

Flow in the bayou was around 400 cubic feet per second (cfs) and dropping.

Violets and Dandelions

After documenting the bend upstream and down, we ventured further down the path and reached the steep banks of the creek that flows from the center of the park, noting that there were several new spontaneous foot paths through the woods.

The ground was mostly bare, scattered with spikey sweetgum seed balls, which like pine needles (see also here), black willows, American beautyberry, and many other things growing on the bayou, have medicinal qualities. The small green leaves of edible wild violets and dandelions were peeking hopefully out of the earth. (Before the freeze, in another part of the park, we had seen some young stinging nettle, a delicacy served in the finest Parisian restaurants.) The water in the winding creek was clear and made a gentle tinkling sound as it flowed over the sand and woody debris. There were large trees fallen across the creek, and in a youthful past the backup photographer, who grew up on the bayou, might have carefully stepped or scooted across these bridges laid down by nature. Or at least watched her brother do it.

The bare winter landscape revealed a haphazard pile of concrete picnic tables, benches, and grills that had apparently been removed from the Picnic Loop and tossed in the woods near the creek. We’ll ask about this thoughtless trashing of the park.

Slow the Flow

What Houston and Other Cities Are Doing to Reduce Flooding

And Make Life Better

Feb. 11, 2021

Despite flooding issues that threaten lives as well as the future of the city, Houston has lagged behind other cities in the state and around the world in encouraging, implementing, or requiring basic steps that can reduce flooding. Harris County, along with six other Texas cities, scored higher than Houston on Environment Texas’ 2020 Scorecard.

But recently the Houston City Council passed a property tax incentive to large commercial developers who use green (nature-based) infrastructure to slow stormwater runoff from their new projects.

Developers are already required to prevent an increase in the amount of stormwater running off projects built on previously undeveloped land. Now Houston taxpayers will actually pay for the cost of doing that if developers use rooftop gardens (green roofs), vegetated swales, permeable paving, trees, etc., known as Green Stormwater Infrastructure (GSI).  Also known as Low Impact Development (LID) or even Sustainable Urban Drainage Systems (SUDS), though the latter also focuses on reusing stormwater.

Slowing stormwater runoff reduces flooding. And in addition to passing the property tax incentive to large commercial developers, the City of Houston recently increased its stormwater detention requirements for new single-family residential projects. This was forced in response to Harris County requirements. No tax incentive yet.

However, the City does reduce the city drainage fee based on the percentage of pervious surface on a lot. So planting a garden on your roof, for instance, changes the roof from an impervious surface into a pervious surface and reduces your drainage fee. (See below.)

Elsewhere, cities like Toronto and Utrecht require green roofs, which can reduce stormwater runoff by more than 50 percent. (Toronto provides financial assistance.) Simply disconnecting roof downspouts from the public stormwater drainage system can help prevent the system from being overwhelmed, a practice recommended by the Environmental Protection Agency.

From California to Illinois to New England, cities are asking residents to disconnect downspouts and instead allow rainwater to flow and soak into a yard, among many other things. (Directing roof runoff onto a concrete driveway, seemingly common practice in Houston, is not helping, since it runs directly into the paved street and into the stormwater system anyway.)

We’ve been gathering information for a while with the intention of eventually posting about what Houston and other cities are doing about flooding. It’s complicated!

Flooding Begins on the Land

A rooftop garden at Annunciation Orthodox School in Houston.

Stormwater is rain that falls and runs across the ground into our built (pipes) and natural (bayous and creeks) drainage system. The harder the surface, the faster the runoff, the higher the flooding in our streets and streams. Also, the more polluted the water. And the uglier and hotter the city.

In recent years, experts have shown that nature-based drainage and detention systems are cheaper to build and maintain as well as more effective in reducing flood risk than pipes and dams, for instance. (See also here.) There are also more benefits, because you end up with trees and native plants, bees, birds, and butterflies, stuff that actually increases the attractiveness and value of property (and our environment).

In addition, there is increasing awareness that it is more practical and effective to manage flooding in place, to stop raindrops where they fall.  As a 2018 study of urban flooding reported, “[m]any cities and towns across the United States are giving considerable attention to plans that support the capture of rain in areas where it falls.” (p. 32)

The American Society of Landscape Architects recommends that every city have a green infrastructure plan, defining urban green infrastructure as “everything from parks to street trees and green roofs to bioswales — really anything that helps absorb, delay, and treat stormwater, mitigating flooding and pollution downstream.”

Nature and Nature-Based Infrastructure is Part of the Resiliency Plan

The City’s Resilient Houston Plan contains our “green infrastructure plan” and more. Creating incentives for green development is part of that resiliency plan.  (p. 36)

Also part of the Resilient Houston Plan is conserving land within the city limits as part of a goal of “increasing the area of the preserved or conserved land in the eight-county Gulf Houston region to 24% by 2040.” (p. 153)

Discouraging development in “sensitive upstream areas,” protecting and restoring prairies and wetlands are also goals of the plan. (p. 151) City boundaries do not extend into the “sensitive upstream areas” beyond the Addicks and Barker federal flood control reservoirs on Buffalo Bayou, for example, although those areas are part of the City’s Extra Territorial Jurisdiction. The  Memorial Villages, which are in the Buffalo Bayou watershed, also are not part of the City. The plan is to work with “regional partners” on resiliency goals.

The initiative to create a tax rebate for green stormwater infrastructure received widespread support. But during review of the legislation over the past year or so, there were also comments, including from a prominent engineering firm, asking why taxpayers should pay for something that essentially costs developers less to install and maintain than conventional grey stormwater infrastructure, works better, and improves the value of their property.

The tax credit is available only to new structures in greenfields (undeveloped land) or redevelopment in brownfields (land polluted by toxic waste) in a tax increment reinvestment zone (TIRZ). The structure must be larger than a building with four residential units, valued at $3 million or more, with at least $200,000 invested in the green stormwater infrastructure.

The credit lasts for ten years and may not exceed the total cost of the green infrastructure. (For details see Ch. 44 here.)

What Some Other Cities and States Are Doing: A Short, Incomplete List

So basically green stormwater infrastructure (GSI) is anything with soil and greenery or a container, or maybe just gravel, even permeable pavement, and, of course, trees, that can divert, absorb, disperse, hold, slow down, and filter rain runoff.  “Daylighting” streams (streams, creeks, etc. that have been buried in concrete pipes) would also be considered green, as are open ditches. We have many creeks and ravines that have been filled in (and built on, flooding as a result). Houston was never so completely flat as advertised.

The City of Houston does provide some small financial incentives to the little people for green infrastructure.  As noted above, the City’s Drainage Fee is based on the amount of impervious surface on your land. That means rooftops, driveways, patios, etc. So reducing the amount of impervious surface on your property reduces your drainage fee.

Here is what some other cities and states are doing or suggesting to make themselves more like “sponge cities”:

Atlanta, Georgia

Austin

Chicago and Illinois

Kansas City, Missouri

Fort Worth

Minnesota and here, too

Nebraska

New York City

North Brook, Illinois

How Non-Native Plants Are Contributing to a Global Insect Decline

Yale Environment 360

The impact of introduced plants on native biodiversity has emerged as a hot-button issue in ecology. But recent research provides new evidence that the displacement of native plant communities is a key cause of a collapse in insect populations and is affecting birds as well.

….

For these reasons, [Doug] Tallamy has proposed a domestic version of Harvard biologist E.O. Wilson’s Half Earth Project. If American homeowners converted half of their lawn to productive native plant communities, he says, they would create a “Homegrown National Park” larger than the Everglades, Yellowstone, Yosemite, Grand Teton, Canyonlands, Mount Rainier, North Cascades, Badlands, Olympic, Sequoia, Grand Canyon, Denali, and Great Smoky Mountains National Parks combined.

Texas Invasives

Texas Invasives is a collaborative effort among various state and federal agencies and other groups to help manage and prevent the spread of nonnative, invasive species in the state.

What Are Invasive Species?

An “invasive species” is defined as a species that is non-native (or alien) to the ecosystem under consideration and whose introduction causes or is likely to cause economic or environmental harm or harm to human health. (Executive Order 13112).

An invasive species grows/reproduces and spreads rapidly, establishes over large areas, and persists. Species that become invasive succeed due to favorable environmental conditions and lack of natural predators, competitors and diseases that normally regulate their populations.

This includes a wide variety of plants, insects and animals from exotic places. As invasive species spread and take over ecosystems, they decrease biodiversity by threatening the survival of native plants and animals. In fact, invasive species are a significant threat to almost half of the native U.S. species currently listed as federally endangered.

Insect Decline in the Anthropocene: Death by a Thousand Cuts

National Academy of Sciences

Many numerically abundant insects provide ecosystem services upon which humans depend: the pollination of fruits, vegetables, and nuts; the biological control of weeds, agricultural pests, disease vectors, and other organisms that compete with humans or threaten their quality of life; and the macrodecomposition of leaves and wood and removal of dung and carrion, which contribute to nutrient cycling, soil formation, and water purification. Clearly, severe insect declines can potentially have global ecological and economic consequences.

More Plants, Less Concrete: Houston Now Will Offer Tax Incentives for Eco-Friendly Development

[SBB is working on a follow-up about this tax abatement program, including a review of what other cities are doing to slow the flow and reduce flooding.]

The Houston Chronicle

The city last month launched a new property tax abatement program for developers who incorporate green stormwater infrastructure, a type of design aimed at minimizing the downstream impacts of development, into their projects. It also boosted incentives for LEED-certified (Leadership in Energy and Environmental Design) projects, an abatement program that has never been utilized, despite being on the city’s books for 10 years.

The stormwater strategies can take different forms, from natural landscapes and gardens with plants and other vegetation that seek to collect or slow runoff, to “green roofs” that apply similar concepts on top of buildings, to permeable pavement that allows water to seep into the ground.

Developers already must meet minimum detention requirements for how much water their projects can detain. Green storm-water infrastructure would not necessarily increase that capacity, but it could retain the water for longer than more traditional projects.

Commercial developers could save as much as 10 percent against their property tax increases when they incorporate green stormwater infrastructure into their developments. The program is open to $3 million projects that include at least an $100,000 investment in the eco-friendly strategy. The maximum abatement is the total cost of the green stormwater infrastructure, effectively reimbursing developers for including it.

Zooming on Buffalo Bayou and Addicks Dam

Public Online Meeting, Tuesday, Jan. 19, to Discuss Issues and Alternatives to the Corps of Engineers’ Answers to Dam and Flood Problems

Jan. 17, 2021

Neighborhood activists in the Addicks watershed in west Houston and beyond have organized an informal online meeting Tuesday, Jan. 19, to discuss alternatives to the Corps of Engineers’ much derided proposals to deal with flooding in and around the overburdened Addicks and Barker flood control dams on upper Buffalo Bayou.

Specifically the Zoom meeting was set up to answer Save Buffalo Bayou’s questions about alleged “bottlenecks” or “flow restrictions” in meandering Buffalo Bayou below Beltway 8 in west Houston. SBB has asked for a definition and the locations of these “bottlenecks.”

The Addicks Watershed Flood Mitigation Network, a coalition of property owners and neighborhood associations around Addicks Reservoir, generally opposes deepening and widening Buffalo Bayou. Nevertheless organizers have tentatively included “de-bottlenecking” as one of their remedies for speeding up drainage from the dams.

Save Buffalo Bayou is in favor of slowing drainage into the dams (and into the bayou below the dams). We are also in favor of restoring meanders on the straightened and narrowed stretch of the bayou upstream of Beltway 8. Unfortunately in the last few years, the county has spent millions of dollars reinforcing the channelized section there with riprap and scraping out the forest to build shallow overflow basins.

The Addicks network has graciously made the Tuesday Zoom meeting open to the public. It starts at 2 p.m. Anyone interested in these issues or with expertise to add is welcome to join.

Here is how to join the meeting along with an explanation of the meeting objectives. These objectives also include a discussion of a recent presentation of Houston Stronger’s Buffalo Bayou Community Plan.

Here is a description of the issues from the Addicks Flood Mitigation Network.

Not Bottlenecks

As Save Buffalo Bayou has pointed out, the issue of bayou meanders being “kinks” or “bottlenecks” was studied by Harris County Flood Control in 2019. Proposals to build artificial meander “bypasses” or even raise bridges were found to have little benefit. However, SBB also has pointed out the numerous stormwater outfalls, installed in violation of federal and county regulations, that block the flow during high water.

The issue of “de-bottlenecking” has been brought up by the Addicks group as part of their many thoughtful alternatives to the Corps of Engineers’ roundly rejected proposal to deepen and widen Buffalo Bayou and build a dam and reservoir on Cypress Creek and the Katy Prairie.

Led by One Creek West, the network is attempting to build a consensus to present to the Corps and congressional representatives. Most if not all of these property owners were flooded in 2017 by the unprecedented level of the flood pool as Harvey stormwater flowing rapidly into the reservoir through tributary streams backed up behind closed Addicks Dam. (Property owners in the flood pool behind Barker Dam also flooded but this group is addressing only Addicks Dam.)

In the very early morning of Aug. 28, 2017, the Corps, fearing that the stormwaters would overtop Addicks Dam, opened the floodgates. This flooded a great many properties along the straightened and narrowed section of Buffalo Bayou above and around Beltway 8. This stretch runs for six miles or so from the two federal flood control dams in far west Houston to just below Beltway 8.

Further downstream, the disastrous flood peak from Harvey, resulting from stormwater draining too quickly from the paved and built city, had already passed on Aug. 27, flooding many properties. This happened with the dam floodgates closed.

Stop Stormwater Before It Floods. Take Responsibility!

Save Buffalo Bayou believes the focus should be on stopping and slowing stormwater runoff before it enters the reservoirs—and before it floods our bayou, our natural and built drainage system downstream. Stopping, slowing, spreading out and soaking in runoff happens with pervious surface (gravel and dirt), disconnecting downspouts, trees, native gardens, swales, green roofs, prairies, wetlands, greenspace and parks, and more. This also cleanses the water and generally makes for a healthier, cooler, and more attractive community.

Neighborhood associations and individuals need to take responsibility for slowing the flow. Every action counts. The longer it takes for rain to hit the ground and enter the stream, the lower the peak flow in the stream. It’s called lag time.

So think of joining the Zoom meeting, which may or may not include representatives of Houston Stronger and others.

Dec. 31, 2020

So 2020 is going out with a boom, possibly some tornadoes, and a lot of rain, which brings up flooding. And watching movies.

We’ve been sort of urgently silent. We’ve been busy listening and working with others, questioning and answering questions, attending virtual meetings, researching the issues to help come up with the best, most effective, most environmentally sound alternative to the Corps of Engineers outrageously backwards plan to widen and deepen 22 miles of Buffalo Bayou and destroy tens of thousands of acres of the Katy Prairie.

Bayou City

In the meantime, today is the last day to watch the FREE lovely films in the Wild Texas Film Tour. These 26 short films include the informative and inspiring “Bayou City,” featuring Armand Bayou Nature Center, Save Buffalo Bayou, Bayou Land Conservancy, and the excellent riparian and urban wildlife programs in our city and state parks departments.

Bayou City was produced by Olivia Haun, the 2018 Wild Texas Film Tour Grant Recipient and Outreach Specialist for the Texas Parks and Wildlife Department’s Wildlife Diversity Program. Over the past two years, Olivia has been traveling to Houston, home to 22 bayou systems, totaling over 2,500 miles of waterways throughout Harris County. Her beautiful short film captures stories from some of Houston’s most passionate and dedicated bayou conservationists and sheds light on the issues the bayou ecosystem has faced over the past century.

Donate

And yes, please. Don’t forget your last minute tax-deductible donation to Save Buffalo Bayou. We need everyone’s help to stay afloat.

It’s Giving Tuesday: So Give It Up for Buffalo Bayou!

They Want to Kill It. We Have to Defend It.

Plus: New Film About Houston’s Bayous Premieres Today!

Dec. 1, 2020

Giving Tuesday is a worldwide day of giving. Today is Giving Tuesday. You probably know this because you’ve already received way too many requests for donations to worthy causes.

Save Buffalo Bayou rarely makes public requests for donations. We are a small organization with a small budget and a big punch. We are fortunate to be able to spend our time doing what we were founded to do: research and write and tell people about Buffalo Bayou and our many streams and creeks, educate the public and our public officials about how forested, meandering streams work for our benefit, why nature is the best engineer. We have nearly 8,000 Facebook followers, plus thousands on our email list, including politicians, agency officials, journalists, tree huggers, and other local residents.

Yes, we are critical and controversial. Who else is going to tell the Harris County Flood Control District (and its bosses) that its policies and practices are counterproductive, contradictory, wasteful, damaging, and outdated? Stripping vegetation and bulldozing the banks of our bayou and tributary streams, for instance? Spending millions to “improve conveyance” of streams flowing into our federal dams that already have too much water flowing into them? (See here and here.) Scientists all over the world, as well as Houston, have known for years that “improving conveyance” to reduce flooding doesn’t work. (See p. 17 and here.)

Now Buffalo Bayou faces its greatest threat in fifty years. The Galveston District of the Corps of Engineers has traveled back in time and come up with the idea of “improving conveyance” in Buffalo Bayou by stripping, deepening and widening this irreplaceable public resource for some 22-24 miles from the dams in west Houston all the way to downtown. In places they would use concrete block to line the bottom and banks.

This would kill the river, destroy its natural functions, as well as all life in it. It would be a costly, never-ending maintenance nightmare.

So the battle continues. Please donate to help us continue the fight. All donations are tax-deductible. Save Buffalo Bayou is a 501c3 nonprofit association.

Bonus: New Film Premieres Online Today!

Maybe you had a chance to watch photographer and conservationist Jim Olive’s beautiful short film Buffalo Bayou: A Right to Life. Take the time to watch Olive’s film, Coastal Essence, about Christmas Bay on the Texas coast and the Christmas Bay Foundation that he started. Coastal Essence was the opening film at the second night of the Wild About Houston film festival Nov. 18, which also featured his Buffalo Bayou film.

Now Texas Parks and Wildlife has produced a new film, Bayou City, premiering online today, Dec. 1, as part of the Wild Texas Film Tour. Produced by Olivia Haun, outreach specialist for the TPWD Wildlife Diversity Program, Bayou City was made to “shed light on the issues the bayou ecosystem have faced over the past century, and to share the successes that provide an alternative vision and relationship between Houston and its bayous.”

Bayou City is one of four short films in the Wild Texas Film Tour. Hosted by filmmaker and conservationist Ben Masters, the films showcase “wildlife, adventure, and conservation stories from across the state.”

The films are available online for free from Dec. 1 through 31, 2020.

FEMA Updates Flood Policy to Support Nature-Based Solutions Rejected by Corps Plan

Nov. 25, 2020

So much happening!

Buffalo Bayou and Tributaries Interim Report

We had an excellent discussion recently about the US Army Corps of Engineers’ controversial ideas for reducing flood risk in the Buffalo Bayou watershed. Mary Anne Piacentini of the Katy Prairie Conservancy and Susan Chadwick of Save Buffalo Bayou talked about the impact of the Corps’ plans and alternatives.

The online discussion Nov. 18 was moderated by independent journalist Sam Oser and hosted by Residents Against Flooding. Here is a link to the discussion.

Engineers Be Engineers

The Galveston District of the Corps of Engineers has $6 million to come up with plans to deal with the problem of increasing storms and increasing development causing too much stormwater flowing too quickly into the federal dams, Addicks and Barker, on upper Buffalo Bayou in far west Houston. The Corps released an Interim Report in early October that focused on deepening and widening Buffalo Bayou for some 22 miles from the dams to downtown Houston. This would be in conjunction with a new dam on Cypress Creek and a 22,000-acre reservoir on the Katy Prairie.

Despite strong support for nature-based alternatives expressed at public meetings sponsored by the Corps in 2019 (p. 199), the Corps outright rejected nature-based alternatives, such as prairies, wetlands, green spaces, restored streams, etc. (p. 6)

However, environmental organizations, including Save Buffalo Bayou, have urged the Corps to reject deepening and widening Buffalo Bayou and building a reservoir on the Katy Prairie. Nature-based approaches are less costly, more practical and effective, quicker, more flexible, and produce a wider range of benefits for the community, including cleaner water and air, cooling, as well as social, mental, and health benefits.

Here is Save Buffalo Bayou’s comment to the Corps.

Here is the Katy Prairie Conservancy’s alternative plan.

Here is environmental attorney Jim Blackburn’s discussion of the plan with the Houston Chronicle’s Lisa Gray.

While the formal public comment period ended Nov. 20, the Corps says it will continue to consider public input and alternatives. The federal agency, founded during the Revolutionary War, expects to have a final draft report and environmental impact statement by late spring or early summer of 2021. There will be another public comment period then.

Here is how to send comments to the Corps about the study.

Here is how to contact federal representatives about the proposals and alternatives.

Note that the Federal Emergency Management Agency just recently updated its flood policy to support nature-based solutions in flood-risk mitigation projects. The Corps itself is under a mandate to incorporate Environmental Operating Principles in its projects and to “engineer with nature.”

Public Meetings, Public Comment: Corps’ Proposed Coastal Barrier

In the meantime the Galveston District, together with the Texas General Land office, is also working on a plan to protect the upper Texas coast and the Houston Ship Channel from a storm surge. (Buffalo Bayou becomes the ship channel four miles east of downtown.)

Recently the Corps released the Draft Feasibility Report and Draft Environmental Impact Statement for the Coastal Texas Protection and Restoration Study, also known as the Coastal Texas Study.

The Corps is holding virtual public meetings on the study on Dec. 3 and 8 from 11 a.m. to 1 p.m. and 6 to 8 p.m.

The deadline for public comment is Dec. 14.

For a highly informed explanation and discussion about the problems and impacts of the Corps’ proposed coastal barrier, watch this Nov. 19 presentation sponsored by Bayou City Waterkeeper, the Galveston Bay Foundation, Healthy Gulf, and the Turtle Island Restoration Network.

Harris County’s Community Flood Resilience Task Force Seeking Nominations. Deadline Dec. 11

Harris County Commissioners Court has approved the first five members of the new Community Flood Resilience Task Force. The new task force takes the place of the long outdated Harris County Flood Control Task Force, established nearly fifty years ago and long dominated by engineers and developers, many of whom did business with the Flood Control District.

The first five members of the task force will select the remaining twelve members of the task force. Their charge is to “ensure Harris County develops and implements equitable flood resilience planning and projects that take into account community needs and priorities.”

The initial task force members were approved by Commissioners Court on Sept. 29. They are:

The new task force is looking for “multi-disciplinary members who are committed to serving the community and represent the geographic, gender, age, racial, and ethnic diversity of Harris County,” according to Judge Hidalgo’s office.

Anyone interested in serving on this task force should submit an application by December 11.
