Triple PG Sand Mine Agrees to Terms of Restraining Order

The Triple PG Sand Mine in Porter has agreed to the terms of a restraining order. The order will force the mine owner to build dikes that can withstand the force of future rains and that can prevent future discharges of process wastewater into the City of Houston’s drinking water.

Certification by Licensed Professional Engineer Required

Furthermore, according to the agreement, a licensed, professional engineer must certify that the dikes can withstand the force of future rains. No more building dikes out of sand. Given where the mine is located – at the confluence of two floodways – it’s not clear whether future breaches are 100% avoidable. It’s also unclear whether a professional engineer would put his or her reputation on the line with such a promise given this particular mine’s history and location.

Southern Perimeter Lacks Effective Dikes

The entire southern perimeter of the mine is flush with the land south of the mine. There appear to be no dikes. So this could be a massive construction job. Dozens of homes south of the mine flooded during Imelda. Debris and damage patterns suggest that floodwaters entered their homes directly from the mine, not from White Oak or Caney Creeks.

Background of Case

In May and again in September, the Texas Commission on Environmental Quality (TCEQ) reported that multiple breaches in dikes at the Triple PG Sand Mine on Caney Creek led to the escape of process water and sediment into the City of Houston’s drinking water supply. The TCEQ had previously cited the mine for similar environmental violations in 2015.

As a result of leaving the breaches open for prolonged periods, the Texas Attorney General sued the mine earlier this month. If the suit is successful, Triple PG could be liable for penalties exceeding $1 million.

Goals of Attorney General

Two weeks ago, I described what the original petition involved. The AG wants to force the mine to stop alleged pollution of the drinking water of the nation’s fourth largest city.

Both the injunction and restraining orders seek the same things: to get the mine to fix breaches so it stops allegedly emitting process water. The initial focus: sealing the mine off so that process water stops intermingling with drinking water. In the long term, however, the state wants to force the mine to build dikes sufficient to withstand the force of future floodwaters.

Requirements of Restraining Order

The agreed temporary restraining order requires the defendant to:

  • Not engage in any operations at its dredge facility that discharge process wastewater from the defendant’s property
  • Not PRODUCE any process wastewater that must be discharged
  • Immediately begin repairing damaged or breached berms
  • Hydraulically isolate any industrial waste within the mine
  • Halt the influx of water from creeks
  • Halt the outflow of waste from pits
  • Construct the repairs to prevent discharges from pits during future rain events
  • Cease and prevent all discharges of any industrial waste and or process wastewater from the mine into waters of the state
  • Within 14 days, hire a professional engineer to assess whether the berms can permanently prevent future discharges
  • Not destroy records
  • Certify all efforts at compliance, also within 14 days

The amended restraining order reset the date for the hearing on a temporary injunction from October 24 to 28th. The last order again resets the hearing date to November 12th.

So why the restraining orders when the original suit asked for an injunction? Generally, restraining orders are sought as a form of immediate relief while a plaintiff pursues a more permanent injunction, although injunctions can also be temporary.

Full Text of Legal Filings to Date

Below are links to the full text of documents filed to date in the case. I obtained them from the Travis County District Clerk in Austin.

Explanation of “Agreed Order”

Notice the word “agreed” in many of the document titles above. An Agreed Order refers to a written agreement submitted by both parties to a case resolving issues between them.

After rendering decisions, courts will often command counsel for both parties to see if they can come up with wording of an order satisfactory to both. If they can, it becomes an “agreed order,” which the court will then enter. (If not, the judge will formulate his/her own order.

Turning the Tide on the East Fork?

If this sticks, it could change the way Triple PG does business forever. It could also improve life on the East Fork of the San Jacinto for residents who have complained about sediment buildups, flooding, polluted water, loss of riparian vegetation, destruction of wetlands, fish kills, and more.

793 Days after Hurricane Harvey and 42 since Imelda

Two Inches of Rain Should Never Have Caused This

Today, we got two inches of rain between 1:30 and 3:20. That’s according to the closest official gage at US59 and the West Fork. See the graph below. Ben’s Branch came out of its banks almost immediately and nearly flooded St. Martha’s Catholic School and Kids in Action again.

Today’s Rainfall in 10-minute Increments

The closest gage at the West Fork and US59 registered a total of 2.08 inches for the event. In ten-minute increments, it looked like this. Source: HarrisCountyFWS.org.

The Result

St. Martha’s School after two inches of rain in a two hour period. This is what the parking lot of the school looked like 1.5 hours after the rain ended. The floodwaters came from Ben’s Branch which was at a virtual standstill in this area. Water under the Woodland Hills Bridge just south of Northpark Drive barely moved.

St. Martha’s has not yet finished repairs from Imelda. No floodwater actually got in the school today, but it came dangerously close for a rain that was not unusual for this area. The school is at least two feet above the hundred year flood plain and this was a one-year rain at best (see table below).

Across the creek, Heather Jensen at Kids In Action wrote, “We’re currently rebuilding Kids In Action for the second time since May. Can’t stomach a third.” Many people would agree with that!

Expect a Rainfall This Intense at Least Annually

The latest NOAA Atlas-14 rainfall chart for this area shows that we can expect a two-inch rain in two hours at least once a year. If you measure the 10-minute peak, it also works out to a one-year event. Which we’ve had several of this year.

I have lived in Kingwood for 35 years and used to own commercial property near St. Martha’s for twenty years. I have never seen Ben’s Branch do this on a rain like we had today.

During those 35 years, not much has changed along the creek. With few exceptions, the bridges, homes and businesses along this portion of Ben’s Branch have been there the entire time.

New Upstream Development is Major Change

However, new upstream development could be adding to the peaks. The City of Houston confirmed after Imelda that the western tail of Woodridge Village empties into the City storm drains. See two images below.

The storm drains, which also empty Sherwood, in turn empty into Ben’s Branch. See image below.

Looking north along Woodland Hills Drive toward Kingwood Park High School, Sherwood Trails and Woodridge Village. The City says this drain helps empty Woodridge Village.

The shot above is looking north, parallel to Woodland Hills Drive. Below, you can see the reverse angle, looking south. The shot was taken from the second floor of Kids in Action on the north side of the creek. Notice how water from that drain is shooting across the creek, creating more turbulence than the flood itself.

Below St. Martha’s, A Different World

Compare the width of the Ben’s Branch channel in the photos above to the width in the photos below, where the stream goes through a natural area.

Upstream from St. Martha’s, Ben’s Branch is a wide channel. Downstream, shown here, it turns into a narrow, twisting, turning creek. Photo from 9/25/2019, courtesy of St. Martha’s.

In the foreground, you can clearly see evidence of erosion from Imelda. This shot was taken on 9/25/2019. Note the fallen tree in the background. Such blockages create “beaver dams” during heavy rains when other debris catches on them. Photo courtesy of St. Martha’s.

Such obstructions, turns, tangles and narrow beds slow the velocity of the water, causing it to back up. No doubt, these factors play a role in the repetitive flooding, as does upstream development.

Political and Legal Obstructions Complicate Matters

Maintenance responsibilities for this portion of Ben’s Branch are in flux. That may be the kindest way to say it. Nothing has really changed since Harvey.

The Bear Branch Trail Association owns the property according to this deed and the Harris County Appraisal District.

However, from reading the deed, you can see that Friendswood still exercises deed restrictions on the property, especially those applying to drainage. When it comes to saying yea or nay to major changes that affect the character of the greenbelt on either side of Ben’s Branch, Friendswood appears to be in control to this day.

Major Friendswood deed restrictions include:

  • Friendswood reserves for itself multiple easements for drainage. (sec. 3)
  • BBTA must keep the area “healthful” (sec. 8)
  • BBTA may not remove any trees except those that are dead or dying (sec. 8)
  • BBTA may not transfer the land (with a few exceptions that don’t apply to this discussion) (sec. 9)
  • The deed restrictions do not have an expiration date like those for many HOAs.

What Next for Ben’s Branch

Last year, the City reportedly agreed with Harris County Flood Control to assume responsibility for all underground drainage in the county would assume responsibility for all above ground drainage. Since then, the two have been trying to sort out responsibilities.

Harris County Flood Control has sought an easement at least since January from Friendswood and Bear Branch Trail Association. Reportedly, they want to remove some trees, and widen and straighten the channel. However, according to a frustrated Houston City Council Member Dave Martin, no agreement has been reached.

Meanwhile the school for more than 500 children almost flooded for the third time in six months. It’s hard to imagine Kingwood without its largest parochial school or one of its most popular day care/after school facilities. It’s time for

Harris County Flood Control should be concluding a major study of all Kingwood drainage soon…including Ben’s Branch. Let’s hope that helps wake Friendswood up to some new realities.

792 Days since Hurricane Harvey and 40 since Imelda

Is Flood Frequency Really Increasing?

By Debbie Z. Harwell, PhD, Editor of Houston History Magazine

Many claims have been made about increasing local flood frequency. They raise the question, “How accurate are those statements?” The report “Significant Houston Area Floods” by Jill F. Hasling, CCM, offers an interesting list for analysis that ranges from April 1837 through February 2019 (two more floods have since occurred in May and September 2019). 

Increase in Flood Frequency

Our first flood took place in April 1837, just eight months after Houston was founded at the confluence of Buffalo and White Oak Bayous. Six months later another flood found Main Street under four feet of water. But Houstonians persisted…and so did the flooding.

In the first 100 years following Houston’s founding, it experienced 36 floods, in the next 82 years, it has seen an additional 146 floods, or four times as many as in the first century.

Broken down into 30-year periods, the trend looks like this. Note that only 3 years exist in the last column so far and it already has more floods than each of the first two 30-year periods.

Note: Last column contains only three years and already has more floods than each of the first two thirty-year periods.

Percentage of Tropical Vs. Non-Tropical Floods

One might think that our location along the Gulf Coast and the tropical systems that come ashore are to blame for this phenomenon, but tropical systems account for only 15% (27) of these events. The other 85% (155) were caused by rain that either fell in large quantities in a short period of time or lingered in the area for multiple days; this includes 22 winter storms.

Early Flood Mitigation Efforts

With the exception of the 1900 Storm, which hit Galveston but also caused fatalities and flooding on the mainland, the worst of Houston’s early floods occurred in 1929 and 1935 (watch video), causing multiple deaths and wiping out homes, businesses, bridges, and the main water plant. With two back to back floods of this magnitude it was time to take action.

In the midst of the New Deal, the federal government put the Army Corps of Engineers in the flood control business. Houston benefited with funding for the Barker and Addicks Reservoirs, completed in 1946 and 1948 respectively, after a delay during World War II. Although creation of two proposed drainage channels north and south of Buffalo Bayou to relieve flooding did not come to fruition, the reservoirs brought some relief along Buffalo Bayou.  

Influence of Urban Growth on Flooding

As Houston grew, so did it’s flooding problem, going beyond Buffalo and White Oak Bayous to include the other 22 Harris County watersheds. By 1983, Houston floods regularly saw the number of inundated homes reach into the thousands. In 1994, ninety subdivisions, including 3,400 homes, flooded. This flood was considered the benchmark for many Kingwood residents to determine the probability that their home might flood in the future. As a result, many did not have flood insurance when Harvey hit because they believed they were safe since their home did not have water in 1994. 

Today some people point fingers at others, saying their flooding problem is of their own making because they built or bought a house in the floodplain, when in fact the area where their homes are located did not have a flooding problem years earlier. Rather, development around them or upstream created issues. (View Kinder Institute’s interactive map of Houston development.)

This has been documented in Meyerland in the last four years, and the most recent floods in Kingwood’s Elm Grove in May and September 2019 also make a  similar case. The Elm Grove homes had never flooded and did not flood in Harvey, but now they have flooded twice in four months with the water levels increasing. Although a definitive cause for the May flood is in litigation, homeowners believe development north of them created the flooding problem. Sadly some of these residents also did not have flood insurance because they figured they were safe after Harvey.

How Quickly We Forget!

Increasingly, these rain events leave our infrastructure overtaxed, whether trying to handle street runoff or rising water in our bayous, streams, and rivers. It seems, though, that many people have let flooding fall off their radar if they were not personally impacted or time has passed, putting flooding out of sight, out of mind.

When the Kinder Institute asked Houstonians in its annual survey what they thought was the “biggest problem in Houston” prior to Harvey but after the Memorial Day 2015 and Tax Day 2016 floods, only 1% spontaneously replied “flooding.” That number grew to 15% in 2018 when asked post-Harvey. But when surveyed in 2019, with only street flooding the year before, the number who identified flooding as our biggest problem dropped down to 7%. Traffic was the leader, going from 24% in 2017 to 36% in 2019. 

The list of Houston area floods clearly shows that Houston has experienced more frequent flooding of an increasingly serious nature. Everyone thought Tropical Storm Allison was “off the charts” until Harvey hit. Imelda was not as bad as Harvey, but in just two short days it managed to be the seventh leading rain event in the nation.

Need for New Ways to Address Flooding

Major floods in four of the last five years demonstrate that the old ways of addressing flooding a little at a time, or doing nothing at all, are not adequate to protect our families, homes, and businesses and maintain our quality of life in Houston.
