West Fork Sludge Fest

The San Jacinto West Fork has turned into a sludge fest again. I took the picture below on 11/11/23. Not since the day that the West Fork turned white have I seen the contrast so dramatic at the confluence with Spring Creek.

This image has an empty alt attribute; its file name is 20231111-DJI_0872-1024x682.jpg
Looking NW from over US59 Bridge. Confluence of Spring Creek (left) and San Jacinto West Fork (right). Cypress Creek joins Spring Creek 2.7 miles west of this location.

In that prior case, the cause was obvious. Two sand mines were discharging process wastewater into the West Fork. The TCEQ determined that one, the Liberty Materials mine, dumped 56 million gallons of white sludge into the river.

This time, the cause is not so obvious. I can’t even be certain I determined the cause. After taking the photo above, I spent a whole day ruling out various possibilities while searching for others.

Ruling Out Causes

The dramatic difference was not caused by huge variation in rainfall totals across the region.

Rainfall totals from Harris County flood warning system. All of the rain fell in the previous 2.5 days and was relatively spread out.

The highest total on the West Fork was that 2.68 inches south of Conroe at SH242. Further investigation showed that 1 inch fell between 3 and 4PM on 11/09/23. That was the highest intensity at that gage in more than a month.

Uneven soil saturation across the region would also not cause the zebra pattern in the river. The entire region is still rated either “abnormally dry” or in “moderate drought.”

And Lake Conroe did not release any large volumes of water lately that would have scoured river banks. That eliminated another potential cause.

Now here’s where it gets really baffling.

SJRA Study Claims Most Sediment Comes from Spring/Cypress Creeks

The San Jacinto River Basin Master Drainage Study by Freese & Nichols claims that more sediment comes down Spring and Cypress Creeks than the West Fork.

In fact, they say, of all the sediment coming into Lake Houston, two thirds comes from Spring and Cypress Creeks while only 13% comes from the West Fork upstream of US59. So where is all the sludge coming from?

In my opinion, it most likely came from new developments or sand mines that move large volumes of loose sediment.

So the next day, I went out with my drone and found several possibilities.

Possible Sources for Sediment Pollution

Two sand mines had pits open to the river, but I did not see large volumes of sediment oozing out of them as I sometimes do.

The most interesting possibility: new developments very near that gage on SH242 that read 2.68 inches.

Two connected developments straddle FM1314 immediately north of SH242. Early plans called them both Mavera. But now, the one on the east has a sign that says Madera. The sign on the west section calls it Evergreen.

Both are being built on top of wetlands in a 10-year flood zone. Together, they have roughly 1400 acres of exposed soil.

Most of the development’s stormwater drains into Crystal Creek and then into the West Fork about a half mile downstream from where I took this photo.

Sediment-laden stormwater burst through the wall of this detention basin.
Enlarged detail from shot above shows water was strong enough to destroy the outfall pipe.

Now let’s see what’s upstream from this breach.

Evergreen drainage channel. Water flows toward camera and the breached detention basin.
Even farther up the channel. Note all recently exposed sediment.

The ditch above appears to be much wider than it was in January 2021, almost three years ago. Now, let’s jump back south to where this area drains into the West Fork.

Crystal Creek (middle) empties into the West Fork (bottom left). Note how milky water from Crystal compares to the West Fork.

Note that the picture above was taken two days after the heaviest recent rainfall, so the volume may not seem impressive.

There likely were other areas along the West Fork that contributed to the sedimentation you saw in the first photo at the top of this post. But I was not in a helicopter and it’s virtually impossible to cover the entire river with a drone. So I can’t say for sure.

How to Report Issues You May See

This is not the first time I have documented excessive sediment coming off the West Fork.

The zebra effect at the confluence is common.

The angle of the shots above varies. But in each instance, the West Fork is the most polluted branch.

Why is sediment so concerning? After all, it’s natural, right?

Remember the mouth bar that virtually blocked off the West Fork after Harvey? Also the one on the East Fork?

When sediment reduces the conveyance of rivers, they come out of their banks faster and higher on smaller rainfalls. The rivers flood more frequently and increase your flood risk.

So, if you see unnatural situations in rivers or streams, make sure you report them to the TCEQ, which investigates such matters.

Together, we may be able to improve our safety and water quality.

2267 Days since Hurricane Harvey

The thoughts expressed in this post represent opinions on matters of public concern and safety. They are protected by the First Amendment of the US Constitution and the Anti-SLAPP Statute of the Great State of Texas.

Northpark South Starts Clearing Wetlands, Floodplain

Colorado-based Century Land Holdings of Texas, LLC has started clearing land for Northpark South in Porter along the West Fork of the San Jacinto River at the west end of Northpark Drive.

Documents from the Houston Planning Commission, USGS, and FEMA; eyewitness accounts from nearby residents and flood professionals; and aerial photos indicate:

  • Most of the area is in floodplains defined decades ago and not updated since.
  • The entire area – and then some – went underwater during Harvey.
  • The entrance to the property near Northpark Drive and Sorters-McClellan Road sits in a bowl that rescue trucks could not get through during Harvey. That would make evacuation difficult in the event of another large flood.
  • Wetlands dot the property.
  • Abandoned sand mines may pose safety threats.

The same developer just completed a sister development called Northpark Woods across a drainage channel from this one. But so far, the gutsy developer has avoided any consequences for its risky gamble thanks in large part to a multi-year drought and interminable delays at FEMA releasing the new post-Harvey flood maps.

All Underwater During Harvey

Eyewitness accounts and damage reports indicate that Harvey floodwaters stretched about a third of a mile east of Sorters-McClellan to Northpark and Kingwood Place Drive. That’s on the high side of Sorters-McClellan; the new development will be on the low side.

Floodwaters in this area stopped at about 83 feet above sea level. However, the entrance to the new subdivision is at 75 feet, according to the USGS National Map. That means the water was an estimated 8 feet deep at the entrance.

One long-time resident in the area said, “The intersection of Sorters and Northpark sits in a bowl. It was not passable by Montgomery County Precinct 4 constables in an Army deuce and a half [used for high-water rescue]. Water from the river came right up past that intersection and continued up Northpark to just past the intersection of Kingwood Place Dr.”

Also on the high side of Sorters-McClellan, six of nine buildings at nearby Kingwood College flooded during Harvey. Restoration cost: $60 million!

And then there’s Tammy Gunnels‘ former home a quarter mile south of the new development. It flooded 13 times in 11 years and had to be bought out by Montgomery County and FEMA.

Documents obtained from the Houston Planning Commission indicate that RG Miller is the engineer of record for Northpark South.

Bordering River and Sand Mines

During Harvey, 160,000 cubic feet per second rampaged down the West Fork behind this property.

Looking west past Sorters-McClellan Road toward what will become Northpark South. Note clearing starting in the middle in what used to be wetlands (see below).

Looking NW. Intersection of Northpark and Sorters-McClellan in lower left. Another subdivision called Northpark Woods by the same developer is in the upper right. West Fork San Jacinto and sand mines at top of frame.

Here’s what they hope to build on this property.

General plan submitted to Houston Planning Commission in 2021.

Current Floodplains Will Soon Expand

Most of the property already sits in floodway or floodplains. But the FEMA map below has not yet been updated to reflect new knowledge gained as a result of Memorial Day, Tax Day, Harvey and Imelda floods.

In fact, the 2014 date on the map below is misleading. It reflects an update of the base map, but the data that determines the extent of floodplains has not been updated since the 1980s, according to an expert familiar with Montgomery County flood maps.

From FEMA’s National Flood Hazard Layer Viewer.

FEMA and Harris County Flood Control have warned people that when new “post-Harvey” flood maps are released in the next year or two, floodplains will expand 50-100%. The floodway (striped area above) will likely expand into the 100-year floodplain (aqua). In turn, the 100-year will expand into the 500-year (tan). And the 500-year floodplain will extend past any of the colored areas.

That’s consistent with eyewitness accounts. And that could potentially put the entire property in floodplains.

Taking Advantage of Map-Update Window

The developer seems to be taking advantage of a window between post-Harvey flood surveys and release of the new maps.

I’m sure the developer’s lawyers would argue that they are complying with all current, applicable laws. But an ethical question arises. Will the new development expose unsuspecting homebuyers to greater-than-expected risk?

If so, why aren’t officials pushing to update maps and floodplain regs faster?

Could some officials be prioritizing economic development now over public safety later?

Certainly not all are. But many flood professionals worry about that.

Next to 5-Square Miles of Sand Mines

The new development sits next to the largest sand-mining complex on the San Jacinto West Fork. Sand mines in this area occupy almost five square miles. However, not all the mines are active. But they still show signs of heavy sediment pollution.

Looking E toward Sorters-McClellan from over West Fork. Northpark South is at top of frame beyond the sand pits.
The operator of this mine decided not to fish its equipment out when they abandoned the site.
More colors than Crayola. No telling what’s growing in these ponds.

Will routing drainage from Northpark South through these sand mines pose a safety risk for people downstream?

Will it be safe for kids to play or fish near these steep-sided pits?

Floodplain Development Called New Form of Redlining

This is an example of why the population of Texas floodplains is greater than the populations of 30 entire states. Yep. Thirty entire states have populations smaller than that of Texas floodplains.

One former floodplain administrator, who requested to remain anonymous, characterized these types of developments as a new form of redlining.

More than a few floodplain and wetland developers target minorities who may not fully understand the flood risk.

Owner financing often accompanies floodplain developments. Such financing can bypass many flood-risk detection procedures that accompany traditional bank financing.

Then, when floods come, the people who can least afford to repair homes suffer the most and longest. Neighborhoods decay faster. And that makes it harder for people to recover their investments.

Years later, the public is left holding the bag. We are asked to fund expensive flood-mitigation projects that would not be necessary had the developer built in a safer area.

2265 Days since Hurricane Harvey

The thoughts expressed in this post represent opinions on matters of public concern and safety. They are protected by the First Amendment of the US Constitution and the Anti-SLAPP Statute of the Great State of Texas.

Swollen San Jacinto East and West Forks Sweep Through Sand Mines

As floodwaters worked their way down the East and West Forks of the San Jacinto from last week’s heavy rains, they invaded sand mines on both rivers on Easter Sunday, 2023.

Up to 9 inches of rain fell in the headwaters of both rivers during 3 days from 4/5 to 4/7. Atlas-14 rainfall probability statistics indicate that equals a 5-year rain.

The Lake Conroe Dam intercepted much of the West Fork rain and is now releasing it at about 6400 cubic feet per second. There are no dams on the East Fork and the flooding there appears much worse.

West Fork Near Northpark South Development

Near the Northpark South Development on Sorters Road, the West Fork snakes its way through four square miles of sand mines. In the image below, the Hallett Mine on the right seemed secure. But the abandoned sand mines on the left and top center both opened to the river.

Photo taken 4/9/2023 two days after rain stopped.

East Fork Near FM2090 on 4/9/2023

Normally, the East Fork at 2090 is about 30-40 feet wide – the size of the opening in the woods circled in red below. But today, the river swelled to about 2000 feet wide.

Looking south from over East Fork San Jacinto toward FM2090.
Looking East along FM2090 across the East Fork.

As the East Fork rose, it invaded the abandoned Texas Concrete Sand and Gravel Mine in Plum Grove.

Abandoned Texas Concrete Sand and Gravel Plum Grove Mine north of FM2090 between East Fork and FM1010

Water entered the northern end, swept through the mine, and punched through the dikes on the southern end, carrying silt and sand with it. See sequence of pictures below.

Looking N toward northern end of mine. Water entered mine in upper left and cut off house.
Water then swept under and around house moving south.
Looking S. The water then exited back into the river through several breaches in dikes.
Rushing water carrying silt and sand found two more breaches close to 2090. Left unchecked, the force of this water will eventually erode the banks of FM2090.
Baptist Church Loop Road south of FM2090 was also underwater.

Mine Fails to Meet Guidelines for Abandonment

This mine does not meet TCEQ guidelines for abandonment. The miners left equipment, including a dredge. They also failed to grade stockpiles, remove buildings, and plant grass. Yet somehow, the TCEQ gave them a pass.

This is the second time in less than two years that this mine has been inundated. The public will bear the cost of dredging all the sand carried downriver.

Ironically, a bill introduced by State Rep. Charles Cunningham requiring financial surety for sand mine reclamation remains bottled up in the House Natural Resources Committee. See HB1093.

I guess the miners need the money more than you do.

SJRA Seeks Public Input on Sediment Trap Proposal

The San Jacinto River Authority (SJRA) recently completed a 246-page conceptual design study, in partnership with the Harris County Flood Control District, that explored the feasibility of implementing sediment trapping facilities (“sand traps”). The purpose: to remove sediment from the West or East Fork of the San Jacinto River. The results and findings of this study have been documented in an engineering report entitled “San Jacinto River and Tributaries Sediment Removal and Sand Trap Development.” 

Prior to proceeding to preliminary engineering design and any subsequent project phases, SJRA is seeking public input on the proposed project alternatives detailed in the report. The full report, as well as a brief summary document, are located on SJRA’s Flood Management Division website. 

How to Provide Input or Ask Questions

Please submit input and questions via email to floodmanagementdivision@sjra.net

Deadline: No later than April 29, 2022

Caution: The full study is dated 1/7/22. But the “brief summary” is dated 3/9/22. Make sure you at least read the executive study of the full report as well as the brief summary. There are important differences.

Overview/Purpose

SJRA says the purpose of the sediment trap study was to assess the feasibility of implementing a pilot project to trap and remove sediment from the West OR East Fork of the San Jacinto. The study only assessed locations where one or more Aggregate Production Operations (APOs) could partner with the the SJRA. They restricted the study this way to reduce costs; the SJRA does not have a source of funding to clean out sand traps and would rely on sand miners.

Initial Concerns

The decisions to:

  • Define the study objective as sediment reduction, not damage reduction and…
  • Only consider locations near sand mines…

…give me mixed emotions about this project.

Pros

On one hand, I look at this and say, “It’s a pilot project. Try it and see if there’s a benefit.” Sediment IS a problem and they believe they can remove up to 100% of the annual sediment load (from the West Fork).

Cons

On the other hand, the study authors, Freese & Nichols (F&N) claimed (in the San Jacinto River Basin Master Drainage Study) that of all the sediment coming into Lake Houston, two thirds comes from Spring and Cypress Creeks while only 13% comes from the West Fork upstream of US59.

Perhaps that’s because they’re using model inputs from a sediment gage at I-45 located 8.5 miles upstream from most of the large West Fork sand mines (page 34, paragraph 3 of full study).

Also, in their discussion of downstream sedimentation mitigation (page 51, paragraph 3 of full study), F&N says that their evaluation was confined to areas where natural processes rather than breeches of sand mine ponds likely contributed to sediment deposition. To see how limiting that is, see the photos of sand mine breeches and their results in this post.

West Fork Mouth Bar
The “Mouth Bar,” a giant sand bar that blocked the West Fork of the San Jacinto, backing the river up into Kingwood and Humble. Thousands of homes and businesses flooded behind this blockage. The above-water portion has since been removed, but most of the underwater portion remains.

In the entire 246-page F&N study and the three-page summary, the word “damage” occurs only once…in relation to erosion damage, NOT flood damage.

It appears that F&N did not even look at creating sand traps where they were most needed, in the headwaters of Lake Houston, because of cost and logistical considerations. Yet the Army Corps, City of Houston, and State of Texas are spending $200 million to dredge that area. One wonders whether SJRA should have looked harder for partners to clean out the traps.

Finally, if sediment traps only work financially near sand mines, the “solution” will not work on other tributaries that F&N alleges contribute 5X more sediment than the West Fork. They just don’t have the sand mines that the West Fork has.

Nature of Proposed Solution

Five years after Harvey, we have a conceptual design and a recommended location: rock-lined channels cut through one or two point bars at the West Fork Hallett mine.

Page 8 of the F&N study shows this schematic of the recommended solution.

The shot below shows the same area in real life. To put the magnitude of the proposed solution into perspective, the solution would cover a little more than an acre. But sand mines like Hallett cover 20 square miles on the banks of the West Fork between US59 and I-45.

2021 photo of sand bar outsde Hallett mine that would have a narrow channel cut through it to trap sand.

My Biggest Fears

My biggest fears with the proposed pilot study are that it:

  1. Asks people to chose from a limited menu.
  2. Could divert attention from better solutions that would reduce flood risk faster in the headwaters of Lake Houston.
  3. Might make the public think the problem is solved.
  4. Could open the door to river mining and further destabilize the riverine environment.
  5. Is not a transferrable solution.

For a pilot study, that last point is troubling.

Also, F&N worries that removing too much sediment from the West Fork could create a “hungry-water” effect that increases erosion downstream. But they have no way of directly measuring how much sediment the West Fork transports. Or what percentage they would remove. That’s because they’re relying on a sediment gage upstream from the sand mines. This introduces an element of risk in the pilot study.

Recommendations Should Be Based on a Holistic Examination of Alternatives

Note lack of vegetation on this steep-sided, eroding bank of Hallett mine on West Fork in foreground.

Before moving forward with the pilot study, I suggest a more holistic examination of additional alternatives that might have a greater impact on reducing flood damage, not just sedimentation. Examples include, but are not limited to:

More on the sand trap proposal in coming days. In the meantime, please review the SJRA’s sediment trap proposal and forward your comments to the SJRA. I will also print thoughtful letters, both pro and con, from responsible parties. Send them to: https://reduceflooding.com/contact-us/.

1671 Days since Hurricane Harvey

The thoughts expressed in this post represent opinions on matters of public concern and safety. They are protected by the First Amendment of the US Constitution and the Anti-SLAPP Statute of the Great State of Texas.

How Soon We Forget!

How soon we forget. Hurricane Harvey was just 4.5 years ago. Since then I have documented dozens, if not hundreds of questionable practices that erode margins of flood safety.

It Didn’t Have to Be That Bad

Harvey was the largest rainfall event in the history of North America. However, with better regulations and construction practices, it didn’t have to be as destructive as it was.

  • Lax regulations;
  • Willful blindness;
  • Development and construction practices that pushed the safety envelope;
  • Relentless destruction of forests and wetlands near rivers and streams;
  • And homebuyers who didn’t realize their true flood risk…

…made Harvey’s destruction worse than it otherwise would have been.

No one factor by itself would explain Harvey’s destruction. But put them all together, and it’s like “death of a thousand cuts.”

The sheer volume of material – more than 1,000,000 words on this site – makes it difficult for people to see the big picture sometimes. To put 1,000,000 words into perspective, the average novel contains only about 100,000. So I’m condensing the website into a book that includes the themes below.

No One Wins Arguments with Mother Nature

During an interview with Milan Saunders and his daughter Lori, Milan said, “No one wins arguments with Mother Nature.” How profound! It doesn’t matter how many surveys, studies and engineer stamps you have on your home’s title. If you don’t:

  • Respect the rivers.
  • Give them room to roam.
  • Protect wetlands.
  • Allow plenty of margin for safety…

…you will flood.

Thought courtesy of Milan Saunders, Chairman/CEO of Plains State Bank. That’s his daughter Lori’s house during Harvey.

Understanding the Causes of Flooding

Excess sedimentation is one of them. Sediment pollution is the single most common source of pollution in U.S. waters. Approximately 30% is caused by natural erosion, and the remaining 70% is caused by human activity.

Large islands built up during Harvey blocked both drainage ditches and rivers. Below, you can see a large sand island (top) built up at the confluence of the Kingwood Diversion Ditch where it reaches the San Jacinto West Fork at River Grove Park. This sand bar reached 10-12 feet in height above the waterline and helped back water up into Trailwood, the Barrington and Kingwood Lakes and Kings Forest. Before the Army Corps dredged this island, River Grove flooded five times in six months. It hasn’t flooded since.

The Kingwood Diversion Ditch and West Fork San Jacinto were almost totally blocked by sediment dams deposited during Harvey.

The second photo above was taken a few hundred yards downstream on the West Fork from the first. It shows “Sand Island” – so nicknamed by the Army Corps. It took the Corps months to dredge this island which they say had blocked the West Fork by 90%.

A certain amount of this sedimentation can be explained by natural erosion. But mankind also contributed to the sheer volume by other practices which I will discuss below.

Respect the Rivers

The red polygons in the satellite image below surround 20-square miles of sand mines on the West Fork of the San Jacinto in a 20 mile reach of river between I-45 and I-69. That exposes a mile-wide swath of sediment to erosion during floods and increases the potential for erosion by 33x compared the river’s normal width.

Even without floods, mines sometimes flush their waste into the rivers. The shot below on the top right shows the day the West Fork turned white. The TCEQ found the source of the pollution upstream: a sand mine that had flushed 56 million gallons of sludge into the West Fork (bottom right).

Influence of sand mines of West Fork San Jacinto water quality.

End the War on Wetlands

Wetlands are nature’s detention ponds. During storms, they hold water back so it won’t flood people downstream. But we seem to want to eradicate wetlands. The images below show the Colony Ridge development in Liberty County. Wetlands (right) are being cleared (left) to make way for the world’s largest trailer park. The acceleration of runoff wiped out FM1010 during Harvey. The road still has not been repaired.

Colony Ridge in Liberty County.

Conservation Costs Much Less than Mitigation

Halls Bayou at I-69 near Fiesta. Image on left shows whole subdivisions that that to be bought out before detention ponds on right could be built.

All across Harris County, especially in older areas inside Beltway 8, apartment complexes, homes and businesses are built right next to bayous and channels. This makes it difficult to enlarge streams or build detention ponds when necessary. One study showed that preservation of floodplains is 5X more cost effective than mitigation after homes flood. Yet private developers keep crowding bayous and residents keep demanding public solutions.

Respecting Individuals’ Property Rights While Protecting Others’

In Texas, it sometimes feels that an individual’s right to do what he/she wants with property trumps others’ rights NOT to flood. You may think you’re protected by all those public servants reviewing and approving plans. But what happens when developers and contractors decide to ignore the approved plans? Here’s a prime example: the Laurel Springs RV Resort near Lakewood Cove.

The approved plans said that “Stormwater runoff shall not cross property lines.” So what did the contractors do? They pumped their stormwater over the development’s detention pond wall. When that took too long, they dug a trench through the wall. Then they laid pipes through the wall to permanently empty the sludge into the wetlands of Harris County’s new Edgewater Park.

This apparently violated the developer’s City of Houston permit, the Texas Water Code, TCEQ’s construction permit and the developer’s stormwater pollution prevention plan. Four investigations are currently swirling around this development. The contractor also cut down approximately 50 feet of trees in Edgewater Park along the entire boundary line and received a cease-and-desist letter from the Harris County Attorney. But the damage is done.

Balance Upstream and Downstream Interests

About 10% of all the water coming down the West Fork at the peak of Harvey came from Crystal Creek in Montgomery County. But the wetlands near the headwaters of Crystal Creek are currently under development. And the developer is avoiding building detention ponds with a “beat-the-peak” survey. This loophole allowed by Montgomery County says that if you get your stormwater to the river faster than the peak of a flood arrives, then you’re not adding to the peak of a flood and you don’t have to build detention ponds. So developers conduct timing surveys to reduce costs and maximize salable land.

What happens when upstream areas develop without consideration for the impact on downstream property owners.

Of course, speeding up the flow of water in a flood is the opposite of what you want to do. To reduce flooding, you should hold back as much water as possible.

The slide above shows part of a new development called Madera at SH242 and FM1314 being built on wetlands near Crystal Creek.

The graph on the right shows what happened on Brays Bayou without suitable detention upstream. Floodwaters peak higher, sooner. Harris County has spent more than $700 million in the last 20 years to remediate flooding problems along Brays.

How much will we need to spend when more areas like Madera get built upstream on the West Fork?

How Quickly We Forget!

FEMA’s Base-Flood-Elevation Viewer shows that in that same area, developers have already built homes that could go under 1-5 feet of water in a 100-year flood. These homes are actually in a ten-year flood zone. And yet more homes are being built nearby. On even more marginal land!

In recent years, the price of land as a percent of a new home’s cost has risen from a historical average of 25% to approximately 40% today. This puts pressure on developers to seek out cheaper land in floodplains, reduce costs by avoiding detention pond requirements, pave over wetlands, and reduce lot sizes resulting in more impervious cover. All contribute to flooding.

Of course, smart homebuyers would not make such risky investments. But few lack the expertise to gauge flood risk. Educating such homebuyers will be one of the major objectives of the book I hope to write.

1639 Days since Hurricane Harvey

Sand-Mine Structural Control BMPs Could Make Difference in Next Flood

In an effort to reduce sediment escaping into the San Jacinto River from sand mines, the Texas Commission on Environmental Quality (TCEQ) has issued Draft Guidelines on Best Management Practices (BMPs). Yesterday, I discussed vegetative controls for erosion. Today, I will discuss structural control. The two types often work together or in sequence.

At the very end of this post, I make some recommendations to strengthen BMPs, and describe how to submit public comments.

Structural Controls

Structural controls do several things:

  • Divert runoff away from disturbed areas
  • Reduce runoff velocities
  • Filter sediment
  • Remove sediment by ponding.

They include the following.

Temporary Structures (Section 2.2.1)

Installed before and during construction. After removing temporary stormwater controls the areas disturbed by the temporary structures must be revegetated.

Permanent Structures (Section 2.2.2)

Permanent structures remaining after construction. Once construction of areas outside of the sand-mining pit has ceased, permanent structural control BMPs must be implemented and operational.

Diversion Ridges, Berms or Channels of Stabilized Soil (Section 2.2.3)

These divert runoff into “sediment basins.” If they remain in place more than 30 days, they must be covered with temporary or permanent vegetation. Maximum allowable drainage area is five acres.

Silt Fences (Section 2.2.4)

Silt fences capture sediment from sheet flow. Six to eight inches of the fence material must be buried in a trench about four inches deep and four inches wide. Silt fences that are not buried have no useful function. They must never be installed across streams. Fencing must be removed when sediment deposits reach one-half the fence height.

Straw Bales (Section 2.2.4 Continued)

Can also be used as sediment barriers in small areas. Maximum grade: 3:1. Water depth must not exceed one foot at any point. Bales with bindings must be entrenched a minimum of four inches and anchored with stakes. Straw bales that are not buried are improperly installed.

Sediment Basins (Section 2.2.5)

Allow retention of sediment “prior to discharge” or recycling. Side slopes must be 2:1 or less. Sediment must be removed when the volume has been reduced to 27 cubic yards per acre of drainage area. Dikes must be well compacted and vegetated. Installed prior to construction but not in flowing streams. Use diversions to direct drainage to basins.

Better structural controls might have prevented a sand mine upstream from discharging 56,000 million gallons of white sludge into the West Fork in 2019.
Riprap Outlet Protection (Section 2.2.6)

Riprap outlet protection must be placed at the outlet end of culverts or channels to reduce the depth, velocity, and energy of water so that the flow will not erode the receiving stream.

Check Dams (Section 2.2.7)

Small dams across swales or drainage ditches that reduce flow velocity and erosion. Not used in flowing streams. Maximum height: two feet. Center must be at least six inches lower than the outer edges to prevent erosion around the edges. The maximum spacing between dams must be such that the toe of the upstream dam is at the same elevation as the top of the downstream dam.

Accumulated sediment must be removed from behind the check dams when it reaches one half the dam height. Erosion around dam edges must be corrected immediately, ensuring that the dam center is six inches lower than the edges.

 Construction Entrance/Exits (Section 2.2.8)

Aggregate must stabilize entrances and exits to reduce sediment tracked onto public roads. Aggregate must be at least six inches thick and 50 feet long. Tire washing may also be needed.

Housekeeping Practices (Section 2.2.9)

Petroleum products, paints, solvents, litter, debris, sanitary waste, and sediment from unstabilized areas, TCEQ BMPs specify:

  • Designated areas for equipment maintenance and repair;
  • Waste receptacles at convenient locations;
  • Regular collection of waste;
  • Protected storage areas for chemicals, paints, solvents, fertilizers, and other potentially toxic or hazardous materials; and
  • Adequately maintained sanitary facilities.
Post-Construction/Stormwater-Management Measures (Section 2.2.10)

Control measures must be installed to control pollutants in stormwater after construction is complete. These controls include, but are not limited to:

  • Retention ponds. Minimum volume is the first inch or half inch of stormwater runoff containing the first flush of pollutants.
  • Vegetated Swales and Natural Depressions. There are grass-lined areas that filter sediments from runoff, thus helping to prevent erosion. Vegetated swales must have side slopes of 4:1 or less.

General

As with vegetative controls, operators must inspect structural controls once every seven (7) calendar days. That includes controls in areas used for storage of materials; maintenance areas; plus site entrances and exits.

Operators must replace or modify ineffective or damaged structural controls “in a timely manner, but no later than the next anticipated storm event.”

Recommendations for Public Comment Structural Controls

As we saw in yesterday’s post on vegetative controls, I have often seen gaps between real and ideal. However, for this post, I realized in looking back through thousands of aerial photos today, that I have never photographed one:

  • Stabilized channel
  • Silt fence
  • Straw bale
  • Check dam
  • Outlet stabilized by riprap or
  • Vegetated swale

…on a sand mine site. Period. Let alone one that met these requirements.

I’m not saying they don’t exist. I’m just saying that I’ve never seen them on the days I flew over.

Maybe operators feel they don’t need them. Or maybe they’re just not using them for other reasons.

So once again, I recommend that you write the TCEQ and ask them to put teeth into their BMP requirements.

In addition, I recommend you request:

  • Stronger wording on the general requirement to fix damaged or ineffective structural controls in a “timely manner.” That’s just too subjective. It lets operators defer maintenance way past the point it may be needed.
  • Clarification on “prior to discharging” in section 2.2.5. Are operators capturing sediment only to discharge it into the river at a later time? What do they mean by discharge? Where?
  • Detention ponds big enough to catch an inch of rain in an area where Atlas 14 requirements specify 16.9 inches of rain in 24 hours? (Section 2.2.10) That seems wholly inadequate. Harris County Flood Control District recommends minimum detention volumes for developments at .65 acre feet per acre for areas up to 640 acres. That’s about 8 inches of rainfall.

Please submit your thoughts on structural control and other BMPs to the TCEQ by emailing Macayla.Coleman@Tceq.Texas.gov with the subject line “BMPs Guidance Document” before August 19, 2021.

The house you save could be your own.

Environmental Regulation Committee Taking Public Comments on Three APO Bills

The Environmental Regulation Committee of the Texas House of Representatives will hear public testimony on three bills concerning sand mines/aggregate production operations on Monday, April 19, 2021. You don’t need to go all the way to Austin to testify. You can leave your comments on the Committee’s website. Just remember, there’s a 5000 character limit. See more about the bills below.

HB 767: Best Practices for Sand Mines

HB767 by Dan Huberty would require the TCEQ to establish best practices for sand mines and publish them on its website. Right now, Texas is one of the few states that doesn’t have a codified set of best practices. Granted, though, some are embodied in the terms of permits and federal laws. But the public never sees these. And many best practices common in other states are notably absent in Texas. For instance, there are no setbacks specified for sand mines from rivers in Texas. Companies can mine right up to the edge of rivers…in the floodway. Then when floods happen, dikes collapse and sediment gets washed downstream.

The Bayou Land Conservancy submitted this letter in support of HB 767. Two key points:

  • Best management practices (BMPs) would provide guidance for the industry and expectations for the community about how these facilities will be managed and the legacy they will leave.
  • BMPs would aid stakeholders in identifying which companies are interested in working with and protecting nearby communities.

HB 767 is scheduled for public hearings in Environmental Regulation on 4/19/2021. To learn more about the bill, click here. To support the bill, go to this web page and leave your comments. It’s quick and easy.

HB 291: Reclamation Plans and Performance Bonds for Sand Mines

HB 291 by Representatives Murr and Wilson calls for sand mines to file a reclamation plan before they get a permit to start mining, estimate the cost of the reclamation, and post a performance bond in that amount. Every time the mine expands, the owners would have to update the plan. The purpose of this bill is to ensure that miners simply don’t walk away from mines after the last ounce of profit is milked from them. That’s what many do now. The East and West Forks of the San Jacinto are littered with abandoned mines and rusting equipment. This bill also specifies the types of things that would have to go into the reclamation plan. It is scheduled for a hearing in the Environmental Regulation committee on 4/19/2021. To learn more about the bill, click here.
To support the bill, go to this web page and leave your comments.

HB 1912: Limiting Sand Mine Pollution

HB 1912 by Wilson would limit air-, light-, noise-, and water pollution; and soil erosion. It also sets limits, mandates monitoring equipment, and requires financial assurance for handling violations. Aggregate production operations throughout the state have had these problems. To learn more about the bill, click here. To support the bill, go to this web page and leave your comments.

Video Broadcast of Meeting

A live video broadcast of this hearing will be available here: https://house.texas.gov/video-audio/. The meeting starts at 2 p.m. or after adjournment of the House for the day.

Texas residents who wish to electronically submit comments related to this and other bills without testifying in person can do so until the hearing is adjourned by visiting: https://comments.house.texas.gov/home?c=c260.

One Sneaky, Bad Bill to Fight

Representative Harris of Hillsboro, TX has introduced HB 2144. Keep this on your radar. It takes away a private citizen’s right to sue for nuisance. For instance, if a sand mine were spewing silicon dust on your property, polluting your water, or flooding your home, you would have to convince the state to sue them. Good luck with that.

“Only the state or a political subdivision of this state may bring a public nuisance action…”

HB2144

This bill has already passed out of committee. So the only way to fight it now is with amendments or on the house floor when it comes up for a vote. I suggest you contact your representatives and try to get them to fight this bill. To learn more about the bill, click here. It does not have a companion bill in the senate but, if approved in the House, would go there for consideration.

Today, nuisance is the most frequently pled theory of liability under common law tort for environmental litigation. Under public nuisance, a plaintiff, either a government entity or a private individual, may bring suit if there are damages, interference, or inconvenience to the health or safety of the public at large. 

HB 2144 would restrict public nuisance law only to cases where a person causes an unlawful condition, namely “an ongoing circumstance or effect … that is expressly prohibited by the laws of [Texas].” Further, the bill specifically provides that persons or entities engaged in “lawful manufacturing, distributing, selling, advertising, or promoting a lawful product” cannot be a public nuisance.  This ignores the fact that people and property can be seriously harmed even though no statute or regulation is violated – that’s one of the reasons we have common law causes like nuisance to begin with!  HB 2144 would remove the ability for the government or individuals to stop such harms from occurring or to seek redress.

Action Alert: Aggregate Production Testimony Needed

Deadline 5pm today, Friday, 9/25: We need you!

Please sign up to speak at an ONLINE/VIRTUAL town hall meeting about sand mines and/or other aggregate production operations (APOs). The meeting will be Thursday, 10/1 for the House Interim Committee on Aggregate Production Operations. Please send an email to both jeff.frazier_hc@house.texas.gov and jeff.frazier@house.texas.gov stating your name, contact info, and your request to speak at the 10/1 town hall.

Probably not everyone will be called on to speak, but we want the committee to know that this affects vast numbers of people. It’s CRITICAL to communicate how many of us are negatively affected by existing and planned sand mines, quarries, concrete plants, and other APOs.

All of the House Interim Committee members will be present and this will be similar to speaking in front of the committee at the Capitol in Austin–but online.

Speakers will also come from the Hill County where APOs are severely impacting quality of life.

Examples of Problems in Lake Houston Area

Speak for Up to 3 Minutes

Be prepared to speak for up to three minutes about how YOU personally have been or will be impacted by quarries, concrete batch plants, or asphalt plants. Pick one or two of these key issues that most affect you personally:

???? Air particulate emissions
???? Water use and availability
???? Water pollution and flooding
???? Rapid development of APOs without adequate regulatory oversight, mine planning, or reclamation
???? Truck traffic
???? Nuisance issues: blasting, noise, odor, light trespass, visible blight
???? Economic impacts, devaluation of property

URGENT: DO TODAY BEFORE 5pm

Just send in an email requesting to speak. You’ll have a week to plan and prep. Thanks for helping protect our families and community!

If possible, it is VERY IMPORTANT to speak at this meeting. However, if you aren’t selected to speak, or you don’t get your request submitted in time, there will be an additional opportunity later this month to submit written testimonial. We’ll send more info on this in the upcoming days and weeks.

Approximately 1,000 Plaintiffs File Suit Against Sand Mines in Harvey Flooding

On February 20th of this year, approximately 1,000 plaintiffs filed a 118-page lawsuit against 55 sand mining companies in the San Jacinto River Basin. Plaintiffs allege that the miners harmed them by decreasing the capacity and depth of Lake Houston and its tributaries by wrongfully discharging and negligently allowing the release of materials into waterways. That reduction of capacity, they say, contributed to flooding their homes and businesses.

Background

To support their claims (¶613), plaintiffs cite violations of Texas Commission on Environmental Quality (TCEQ) regulations and the U.S. Clean Water Act. They claim:

  • Excessive, unauthorized discharge of silt into waterways
  • Failure to:
    • Obtain stormwater discharge permits
    • Prevent unauthorized discharges
    • Minimize generation of dust and off-site tracking

Past and Present Activities Cited

Some defendants, they say, operated above permit limits and others operated without any permits at all (¶614).

Plaintiffs say (¶615) that defendants have operated immediately adjacent to various waterways and in the flood plain, clearcutting all vegetation, and digging pits within feet of the riverbanks. Thus, there are no real barriers between mines and the rivers, they claim. Further, they allege that defendants have no plans in place for protection and preservation of their pits and loose sand during flood events, which occur frequently.

Then Came Harvey

Hurricane Harvey, they say, inundated mines and “thousands of acres of sand washed downstream, clogging the rivers and lakes, resulting in flood waters moving outside the banks and outside the flood plain, causing hundreds of millions of dollars in damages.”

Alleged Violations of Water Code

The defendants had a duty to implement procedures to reduce the discharge of sediment into waterways, but did not, according to the plaintiffs. Thus, the proximate cause of plaintiffs’ injuries involved negligence and negligence per se. Defendants allegedly breached their duties under sections 11.086, 26.039, and 26.121 of the Texas Water Code, thus causing flooding and damage to plaintiffs’ property.

To prove negligence, personal injury plaintiffs must show that the defendants’ conduct fell below the applicable standard of care and that their actions were the actual and proximate cause of harm. 

In cases of negligence per se, defendants’ actions are assumed to be unreasonable if the conduct violates an applicable rule, regulation, or statute. That’s why lawyers cite the Texas Water Code, plus TCEQ and EPA regulations.

  • 11.086 of the Texas Water Code provides that no person impound the natural flow of surface waters, or permit impounding to continue, in a manner that damages property of another by the overflow of the water diverted or impounded.
  • 26.039 specifies that mine operators must notify the TCEQ of accidental discharges or spills that cause or may cause pollution as soon as possible.
  • 26.121 prohibits discharge of pollutants. Both the EPA and TCEQ consider sediment a pollutant.

Specific Omissions

Specific omissions, say the plaintiffs, include failing to:

  • Locate sand mines outside of floodways
  • Increase the width of dikes
  • Decrease the slope of dikes
  • Control erosion with vegetation
  • Replant areas not actively being mined
  • Protect stockpiles from flooding
  • Mine only above the deepest part of the river

Nuisance Claim

The plaintiffs also allege nuisance. Under Texas law, nuisance refers to a type of legal injustice involving interference with the use and enjoyment of property. Specifically, plaintiffs say that the defendants’ negligent conduct caused paintiffs’ flooding, thus depriving them of the use of their homes.

Complaint against Forestar by Barrington Residents

On page 108, a subset of plaintiffs (those who live in the Barrington), lodge a complaint against Forestar (USA) Real Estate Group Inc. They allege that Forestar developed, marketed and sold homes in the subdivision without any standards for determining the elevation of a house relative to flood risk.

“Despite having actual knowledge of the possibility of flooding in the Barrington Subdivision, Forestar did not advise homebuyers to purchase flood insurance,” says the complaint (¶640). “Nor did Forestar advise the residents of the Barrington Subdivision of its location on a floodplain, or that their elevations were changed due to lots being filled with dirt” when residents purchased homes.

Nevertheless, the complaint continues (¶643), homes were built at an “unreasonably low” elevation, given their location near the West Fork San Jacinto. “Forestar knew, or should have known, that houses needed to be built at an elevation adequate to prevent and/or reduce the likelihood of flooding.”

Damages Alleged

Plaintiffs allege damages that include:

  • Cost of repairs to real property
  • Cost of replacing personal property
  • Lost of use of real and personal property
  • Diminution of market value
  • Loss of income, business income, profits and business equipment
  • Loss of good will and reputation
  • Consequential costs, such as loss of time from work and alternate living expenses
  • Mental anguish
  • Pre- and post-judgement interest
  • Court costs

Conscious Indifference and Gross Negligence

¶658 asserts that the conduct of all defendants (sand mines and Forestar) qualifies as gross negligence under Texas law. The plaintiffs say that the defendants acts of omission involved an extreme degree of risk, considering the probability and magnitude of harm to others. Plus, “Defendants had actual subjective awareness of the risk involved in the above described acts or omissions, but nevertheless proceeded with conscious indifference to the rights, safety and welfare of plaintiffs and others.”

Where Case Stands

129th District Court Judge Michael Gomez signed a docket control order on 2/28/2020 that calls for:

  • All parties in the suit to be added and served with notice by 8/19/2020
  • Close of pleadings and start of mediation on 12/16/2020
  • End of discovery on 1/15/2021
  • All motions and pleas heard by 1/15/2021
  • Trial, if necessary, on 2/15/2021

To date, there have been several motions to transfer venue, dismiss the case, and change the judge.

Only Triple PG Sand Development, LLC has filed an answer to the plaintiffs’ claims; the company filed a general denial.

In a separate case, the Attorney General of Texas is suing Triple PG for failing to prevent and repair breaches in dikes that resulted in repeated unauthorized discharges of process wastewater and sediment into Caney Creek. Caney Creek joins the East Fork San Jacinto just downstream from Triple PG. Triple PG currently operates under an injunction that bars it from dredging.

Editorial Opinion

If successful, this case may force sand mines to operate more responsibly, now and in the future. For instance, it might force them to move farther back from rivers and out of floodways. Having taken thousands of photos of leaking sand mines from the air since Harvey, in my opinion, that might benefit everyone, not just the plaintiffs.

As Heavy Rains Approach, Triple PG Wastewater Higher on Neighboring Properties Than In Its Settling Pond

Aerial photos taken on 5/11/2020 show wastewater on neighboring properties outside the Triple PG mine in Porter are higher than in the mine’s settling pond. If heavy rains materialize this weekend as predicted, that wastewater could be flushed downstream into the drinking water for 2 million people.

Mine Has History of Dumping and Pumping

Earlier this year, I photographed the mine pumping wastewater from its settling pond toward the neighboring properties. A TCEQ investigation confirmed that wastewater had exited the mine for the fourth time in a year. Investigators found that the wastewater had levels of suspended solids 676% higher than water from nearby White Oak Creek. But they also found that elevation differences had confined the wastewater and kept it from entering the wetlands near White Oak Creek.

Heavy Rains, Flash Flooding Could Flush Water Downstream

However, heavy rains predicted for later today and Saturday could change that. Jeff Lindner, Harris County Flood Control meteorologist says rainfall rates of 1-3 inches per hour will be possible and there is a slight (10-20%) risk of flash flooding, both days. Isolated totals could reach 6 inches on Saturday, he predicts.

How High Is Water On Neighboring Properties

So how high is the water outside the mine compared to inside?

In the photo below, note the two sets of arrows on either side of the road. The strip of trees under the upper right arrow does not belong to the mine. However, the land under the lower right arrow does belong to the mine. I included the second set of arrows because they are closer to the camera and that makes it easier to see the elevation difference in the water. Notice how much higher the water is on the right than on the left relative to the road.

Looking east over flooded properties (inside tree-line) that neighbor mine. Photo taken 5/11/2020.
Terms of a temporary injunction restrict the mine from using its dredge. So the mine has started dry (or semi-dry) excavation. That meant removing wastewater from this pit. Photo taken 5/11/2020.

On January 20, 2020, I photographed the mine pumping water out of its settling pond toward adjoining properties. See below. The pit above can be seen in the upper left of the photo below.

See the pipe cutting diagonally from the middle of the frame to the lower right. Also note, the pond in the upper left of this image corresponds to the pond in the foreground of the image below. Note water level on January 20, 2020
By February 13, three weeks later, that pond was largely empty. It is common for mines to pump water from one pond to another. But illegal to pump water outside the mine.

Why Mines Should Not Flaunt Rules

If approaching storms flush sediment- and chloride-laden wastewater downstream, it will end up in the San Jacinto East Fork and Lake Houston, the source of drinking water for 2 million people.

This underscores the need for the state legislature to pass laws that move mines out of the floodway. The Triple PG mine actually sits at the confluence of two floodways. That makes it vulnerable and dangerous…especially when an operator apparently flaunts rules designed to protect the safety of the public.
