Interview with Corps’ Chief of Evaluation: What’s Next for Romerica?

After receiving 727 public comments, Kingwood Marina developer, Romerica Investments, LLC, asked Corps regulators on April 24, to “temporarily suspend an Individual Permit Application (SWG-2016-00384).”

Romercia’s environmental consultants said in a letter to Corps regulators, they made the request based on the large volume of comments provided by the U.S. Army Corps of Engineers (USACE) on March 28.

The request acknowledged, “It will take several months to conduct the surveys and studies needed to respond fully to these comments.” 

Interview withCorps’ Chief of Evaluation Branch

Last week, I spoke with Janet Botello, Chief of the Evaluation Branch of the U.S. Army Corps of Engineers/Galveston District. We talked about what comes next for Romerica after its permit application for the proposed high-rise development in Kingwood was withdrawn by the Corps. Bottom line: if they reapply, we would likely have another public comment period.

In this satellite image taken on 2/23/19, you can see the West Fork San Jacinto at the bottom, River Grove Park at the left, Kingwood Country Club on the right and the Barrington at the top. Romerica hopes to build multiple 25-50 high rises between the little lake in the center and the golf course fairways below the Barrington.

Difference: Suspension vs. Withdrawal

Rehak: “Romerica requested a suspension of their permit application. The Army Corps withdrew it. What’s the difference? Is there any legal significance?”

Botello: “The correct wording in this case is “withdrawal.” There IS a legal difference. There is a provision within our regulations for suspending a permit. But that only occurs when a permit has actually been issued. In this case, the permit was not issued; there was only an application. We never made a final decision. So the pending application was withdrawn.”

Another Public Comment Period Likely

Rehak: “If they reapply, would there be another public comment period during the evaluation of new application?”

Botello: “I am comfortable in saying that there probably will be another public comment period based on the number of public interest factors and concerns that were raised and potential changes that could occur. But we won’t know for sure until we get the revised packet of information.”

Rehak: “How frequently does this happen?”

Botello: “It’s common. If a significant number of comments are raised during the public comment period and applicants aren’t prepared to address them within 30 days, we withdraw it. Then they go back and try to answer the concerns that were raised or revise their plans. Conversely, if they can answer and fully address concerns within 30 days, we keep evaluating the permit and we go ahead with the next step. If not, we withdraw it and give them time on their own to address the public concerns.”

Next Steps If Romerica Reapplies

Rehak: “What will be the next steps if Romerica reapplies?”

Botello: “First, we will evaluate the new submittal internally for a review of the Corps’ concerns. Then we will draft a public notice for public review – to gather public concerns. Then typically, we gather up the comments and concerns raised after that 30-day period, and forward them again to the applicant. They will have to respond within 30 days and then we will gather their responses and determine what steps are appropriate.”

Where We Are At

Romerica has not returned phone calls to discuss their intentions. If other agencies had concerns as serious as the TCEQ’s, this project could die quietly. If Romerica reapplies, which they have said they will do, the developer will likely have to significantly revise plans, and start over with a lengthy permitting process including a new public comment period.

Senator Creighton Responds to Concerns About SB 2126

Note: I have created several posts about SB 2126, a bill proposed by Senator Brandon Creighton. While I support the Senator’s efforts and objectives, I feel the bill’s language could open the door to river mining. Senator Creighton disagrees and offers following.

After Harvey, fresh sand deposits several feet thick lined both shores of the west fork of the San Jacinto. The issue: What’s the best way to keep sand from migrating downriver where it can accumulate and contribute to flooding?

To the Editor

First off, I would like to thank Mr. Rehak and ReduceFlooding.com for being a leader in our communities on all aspects of flooding. Your efforts represent the sort of grassroots organizations that impact government and the community.  Reduceflooding.com also serves as a useful resource for residents to educate themselves on flooding, policy initiatives and upcoming events. 

Background

Since Harvey made landfall, we have worked tirelessly with one another to do what is best for the Lake Houston area. We have been on tours together with statewide officials and we have been in dozens of roundtables in Austin and in Kingwood. These meetings included state agencies such as the GLO and TCEQ, local representatives like Council Member Dave Martin, myself and Representative Dan Huberty, Commissioner Cagle, Congressional members such as Ted Poe and Dan Crenshaw, and most importantly, members of the community. Our meetings resulted in helpful policy recommendations on what needed to be done back then, and a vision for the long-term. And now, the long-term is here and we must act this session. 

The Bigger Picture

One of the biggest actions taken thus far was the Senate’s passage of hurricane preparedness and response packages, S.B. 6, S.B. 7, and S.B. 8. My bill, Senate Bill 7, creates the Texas Infrastructure Resiliency Fund, a new fund that will provide unprecedented state funding to cover the nonfederal, local match resulting from Hurricane Harvey as well as provide funding for future mitigation projects that will include upgrading the water gates on the Lake Houston Dam. The state playing the nonfederal role will bring billions of your tax dollars back to Texas from D.C. and will finally result in the feds helping Texas as we have stepped up to assist other states time and again.  

Aggregate Related Proposals

We also filed bills to increase the enforcement of sand mining along the San Jacinto River basin. Senate Bills 2123, 2124, and 2125 were discussed in our roundtable meetings and were generally supported. These bills increase penalties, direct funds to enforce penalties for illegal sand mining, increase the frequency of mandatory sand inspections from every three years to every two, and creates a best practices guide for aggregate producers to follow. 

Where SB 2126 Fits In

Senate Bill 2126 was the next step. This bill passed the entire Senate this week and heads to the House of Representatives. This approach was one of the many discussed at these roundtables and I appreciate you acknowledging the good intentions of this bill. I hear your concerns, and I respect your point of view, however I believe this program will yield many benefits for the community.   

How Safeguards Would Be Implemented

I want it to be clear, this bill will not open up unbridled sand mining in the San Jacinto River basin, and there are many precautions in place to ensure the river basin is protected.   Rather than prescribing arbitrary guidelines in the bill, we will depend on the San Jacinto River Authority and Harris County flood control district expertise to formally and publicly adopt rules, controls, best practices and other safeguards. 

Alternative to Repetitive Dredging

This solution is an outside-the-box approach to a problem identified by the U.S. Army Corps of Engineers. While we have worked hard to expedite and fund the current dredging project underway in the River, it is inefficient and impractical to come back every 10 years to dredge in the River. There must be a long-term solution, and I think this legislation can play a role.

Oversight Authority

SB 2126 will allow the San Jacinto River Authority and the Harris County Flood Control District to place traps in the River. These are stationary traps that will capture sand that naturally deposits in undesirable locations. This does not allow for sand mining to continuously occur in the River or on the banks. We are delegating this authority to these public entities because they are accountable to you. They are entrusted with carrying out many other important duties to protect the resources of all Texans and this is one more way for them to play that role. 

Offsetting Costs Through Sale of Sand

Kaaren Cambio, a newly appointed SJRA board member from Kingwood recently said, “A long term maintenance plan for the San Jacinto River is key to protecting the adjacent communities. We must have many options available to make this plan effective and financially feasible. Public-private partnerships are critical to achieving this goal. SB 2126 gives the SJRA the opportunity to have specific areas dredged and the cost of the dredging is offset by the sale of the sand.”

Council Member Martin’s Endorsement 

Houston City Council Member Dave Martin, who has been an invaluable voice as we address flood mitigation expressed the following sentiment, “Senate Bill 2126 is a key legislation item that will allow aggregate production operators to be part of the sand remediation solution by giving them the ability to introduce sand traps into the West Fork of San Jacinto River. The ability to use sand traps on the West Fork will allow for sediment to fall out of an otherwise sediment rich body of water, thus reducing sediment deposits downstream which can clog up the river and lake. As the Houston Council Member who represents Lake Houston, this bill will help our area avoid additional mouth/sand bars and sediment buildup. I hope this piece of legislation serves as a pilot study the rest of the State can learn from.”

Support of Game Wardens

You noted that Texas Parks and Wildlife testified as a resource for the bill. State agencies remain neutral on legislation because they are agents of the State, but the Texas Game Wardens Peace Officers Association did support the bill at the hearing. They recognize the problem we have and how SB 2126 can be a practical solution. 

Plea to Continue Working Together

Recent floods, and especially Hurricane Harvey exposed serious weaknesses, and I hope that this bill and other components of our legislative flood solution package will serve as effective solutions for Kingwood, Lake Houston and surrounding areas.  If we identify any problems down the road, I hope that you will be a partner and advocate for getting projects back on track.  I know we will continue to work together to ensure the best mitigation efforts are followed.  

Again, I am so appreciative of the work you and all the community leaders have done to make the Lake Houston area a better place to work, live, and raise a family. I look forward to our continued collaboration to achieve that goal. Please feel free to reach out to me and my staff if we can ever be of assistance. We have made some incredible progress – see my newsletter here – and hopefully these policy initiatives will pass during the legislative session and improve our readiness for future storms ahead.

Harris County Flood Control Issues Storm Report for Last Friday, Saturday: Here’s What Hit Us

Someone on Facebook asked, “How did the May 3 and 4 storms in Kingwood compare to surrounding areas?” Here’s the answer – from Jeff Lindner, Harris County Flood Control’s chief meteorologist.

Storm Report for Lake Houston Area

Kingwood, Harris: Straight line winds of 65-70mph produced a swath of damage across a portion of Kingwood including damage to some roofs as well as trees and power lines.

Woodland Hills between River Grove Park and Romerica Property. Brief rainfall on 5/3/19 exceeded capacity of drainage ditches and culverts, forcing part of the water to divert down greenbelt trail toward wetlands in River Grove Park. Video courtesy of Mohamad-Khaled Chaouki Jrab.

Lake Houston, Harris: public video of waterspout over Lake Houston just north of the FM 1960 bridge and near the eastern shore of Lake Houston

Storm Report for Surrounding Areas

LaGrange, Fayette: Tornado ***EF-2** * 120mph winds. 2.48 miles long and 75 yards wide.

Tornado began south of the airport where heavy tree damage occurred and then approached HWY 71 where heavy damage occurred to a business where vehicles were overturned. A 90,000 pound piece of machinery was shifted and overturned…rated EF 2 at this location. The tornado continued north and crossed HWY 71 destroying a metal building and heavily damaging a church. The tornado dissipated just south of the Colorado River.

Eagle Lake, Colorado: Tornado ***EF-0*** 65-85mph. Spotter, fire department, and emergency management officials reported and recorded on video a couple of weak tornado touchdown in open rural farm land SW and S of Eagle Lake. Damage was confined to trees over open land. 

4SW Monaville, Waller: wind damage to trees….possible tornado. Public cell phone video near the time of the report and radar data showing a velocity couplet supports a brief and weak tornado touchdown. This was the start of the supercell cell that would produce wind damage across N Harris County and another tornado near Tomball.

Tomball, Harris: Tornado ***EF-0*** 65-85mph. Trained storm spotter recorded a large funnel cloud west of Tomball that appeared to have at least one portion of the funnel reach the ground. Wind damage occurred near FM 2920 and Telge Rd, which was near the video of the funnel cloud. Additional wind damage occurred north of FM 2920 and north of Tomball along Hufsmith Rd.

Spring, Harris: wind damage including a large pine tree onto a house.

Matagorda, Matagorda: 46mph wind gust recorded by Weatherflow site

Santa Fe, Galveston: roof and damage to a home on Gamble Rd from straight line winds

San Leon, Galveston: 62mph wind gust recorded by Eagle Point PORTS site

Galveston, Galveston: 45mph wind recorded near Fort Crockett

614 Days after Hurricane Harvey

Severe Weather, Heavy Rainfall Threats Return for Much of This Week

Keep your eye on the sky for more severe-weather threats this week. Harris County Flood Control Meteorologist Jeff Linder warns that the coming week could bring us 5-7 inches of rain, and higher totals in places. He says the upper level trough setting up over the southwestern US will send us one storm after another. Linder compared the current pattern to those in the springs of 2015 and 2016. We saw multiple floods across Texas in both of those years.

Rainfall total forecast for May 5 through 12.

Monday Night/Tuesday: Saturating Soils

A strong disturbance will move into southeast Texas on Monday night and Tuesday with widespread showers and thunderstorms. Heavy rainfall of 1-2 inches with higher isolated totals will be possible along with a slight severe weather threat. Lindner thinks “most of the area will be able to handle this round of rainfall as long as there is no sustained cell training that develops and the overall forward progression of the system remains fast enough to prevent rainfall totals from piling up.” What this system will likely accomplish is further saturation of the soil over the area. Lindner calls it a “primer” event for more sustained heavy rainfall toward the end of the week.

Thursday-Saturday: Flood, Severe Weather Threats

Another strong storm system will approach toward the end of the week along with a slow moving and stalling surface frontal boundary. An extremely moist air mass along with the overall slow eastward progression of the storm system moving out of Mexico are significant heavy-rainfall signals during this period. Lindner expects several inches as several rounds of slow-moving thunderstorms impact the region. Flooding and severe weather will be possible during this period. 

Rainfall Totals and Flood Risk

Rainfall totals over the next 5 days should average 4-5 inches over much of southeast Texas and there will almost certainly be higher isolated totals. The widespread nature of the incoming weather this week on top of increasingly saturated grounds, and already swollen rivers, creek, and bayous increases the flooding threat. Main concern will be the Brazos, Trinity, and San Jacinto River basins and toward the end of the week the Harris County bayous and creeks if the current forecast holds. 

Exact timing of the rainfall and storms as well as amounts and locations of the higher totals will be in flux over the next 5 days. 

Although some street flooding is possible, I suspect the main threat will be river flooding this time.

Things You Can Do to Prepare

The Tax and Memorial Day Floods in 2015 and 2016 did as much damage as many hurricanes. So it would be good to prepare an evacuation kit, just in case. Here are some tips.

Get a backup battery charger for your cell phone in case of extended power outages. Remember the 13 days Kingwood went without power after Hurricane Ike?

Change out the batteries in your flashlights and weather radio. Remember those? They still work!

Learn how to read cloud formations and what they mean. Here’s a link to a well-illustrated article about threatening cloud formations. You may also want to search for “cloud formations before tornados.”

Move your vehicle to higher ground, preferably inside a garage. Remember, large hail often occurs with severe storms and can destroy a car’s finish.

After a flash flood, stay home or stay at work.

One Less Thing to Worry About in Latest Storm: How Seasonal Lowering of Lake Conroe Helped

Storms during the last two days were traumatic for virtually everyone in the Kingwood area. Tragically, one person lost her life when her car hit a downed tree.

  • Others lost vehicles, trees, and sleep.
  • Torrential rains for a brief period – at the rate of 4-5 inches in an hour – flooded streets and vehicles.
  • They also brought water near or into homes.
  • Parents picking children up from school waited in rising waters as their students sheltered in place.
  • A small tornado may have briefly touched down near Town Center.
  • Kingwood Drive was shut down for hours during the Friday afternoon rush hour.
  • People traumatized by Harvey were re-traumatized.
  • People without power waited and wondered for hours about what was going on around them.

Lake Conroe: One Less Worry This Time

Despite all that, we did NOT have to worry about one thing: Lake Conroe opening its flood gates again during this storm. The seasonal lowering policy established last year worked.

The SJRA board voted to lower the lake’s level one foot to 200 mean feet above sea level (MSL) from April 1 to May 31.

That action may have saved the Lake Houston area from additional flooding in the last round of storms.

Releasing Water Continuously At Low Rate Created Extra Capacity

Lake Conroe had released water continuously since April 1 at a slow, controlled rate of 350 to 550 cubic feet per second. However, because of spring rains, Lake Conroe had only dropped about a half foot from 201 to 200.66 feet MSL. Had the releases not happened, the lake would have been an estimated 1-1.5 feet higher, according to Mark Micheletti, an SJRA board member from Kingwood. That means the lake level would have been approaching 202 feet, the level at which the SJRA automatically begins releasing water, when the storm hit. That would have forced the SJRA to release water at a higher rate that could have overloaded the downstream watershed.

Buffer Against Downstream Flooding Worked

In other words, the policy worked. The seasonal lowering provided a buffer against downstream flooding. NOAA shows a double crest on the San Jacinto West Fork at US59 during the last two days that coincided with two waves of storms. At peak flow, the river came within about two feet of going out of its banks.

An additional foot of water released from Lake Conroe would have added two feet to Lake Houston and created flooding.

About a mile downstream at River Grove Park, the water was up, but still within its banks.

Despite torrential rains last night and early this morning, the West Fork remained in its banks. The river was up, but no homes flooded from the river.

Success: No Rivers or Streams Out of Banks

At this hour, neither NOAA, the SJRA, nor Harris County Flood Control, predicts any flooding from yesterday’s storms. In fact, all streams and bayous seem to be receding at this time. That’s one less thing to worry about as we clean up from the latest storm. The SJRA’s seasonal lowering DID help.

Remember, Lake Conroe is almost twice as big as Lake Houston (33 sq. mi. vs 18.5 sq. mi.). So one foot released there translates into almost two feet here. And two feet would likely have forced the San Jacinto out of its banks for the fifth time in a year.

Kudos to the SJRA board, the City of Houston, and the TCEQ for enabling this policy. That, in conjunction with the City’s pre-release policy for Lake Houston, have made a difference.

Street Flooding vs. River Flooding

During Harvey, most of the damage in Kingwood happened from river flooding. Yesterday, it happened from street flooding. What are the respective causes? Differences? Fixes?

River Grove Park the morning after the street flooding during the previous day and night. The river was still well within its banks and is not predicted to come out.

River Flooding Overview

River flooding happens when heavy rainfall exceeds the conveyance capacity of a river. In other words, the river comes up and out of its banks. This happened to the San Jacinto during Harvey. The river, normally a couple hundred feet wide, became three to four miles wide, inundating miles from the main current.

River flooding can be caused by heavy rain, upstream snow melt, dam/levee breaks, dam releases, and more. Most commonly, it takes hours to days for water to work its way through a river system and affect people downstream.

River Flooding Remedies

Fixes for river flooding include things like:

  • Building dams upstream to reduce the flow downstream.
  • Increasing the conveyance of the river through widening, deepening or dredging
  • Removing blockages such as the mouth bar on the West Fork of the San Jacinto
  • Increasing the outflow capacity, for instance by adding gates to dam
  • Building levees
  • Diverting water to tunnels.

Street Flooding Overview

Street flooding, on the other hand, is often much more local and happens over shorter periods of time. It is often referred to as flash flooding because it comes up quickly and goes down quickly. That’s what the Lake Houston Area experienced yesterday. The San Jacinto, its tributaries and drainage ditches were and still are well within their banks.

Flash flooding occurs when the rainfall RATE temporarily exceeds the drainage capacity of storm drains, sewers, swales, and ditches that lead to rivers.

Yesterday, we received 1/20th the amount of rainfall that we did during Harvey, but many people reported the water coming up higher. That’s because storm sewers could not handle the intense rainfall that happened during approximately a one hour period.

Drains on Valley Manor could not handle the sudden surge.

Streets Designed as Part of Flood Retention System

The streets in Kingwood (and most cities) are actually designed to be part of the flood retention system. When developers excavate streets, they often use the fill to build up homesites. By increasing the elevation difference between street level and your foundation, they reduce the chances that you will flood.

They size the sewers so as not to make drainage ditches overflow. Rainfall rates like we experienced yesterday don’t happen for very long. The storm passes. The water in the street goes down and life returns to normal. You just don’t want to be caught out on the road in your car when it happens. Nor do you want to have your car parked on the street!

Street Flooding Remedies

The Greater Houston Flood Mitigation Consortiums’ report on Harvey contains an extensive discussion of the different types of flooding. Their discussion of street flooding starts on page 14. Page 15 identifies solutions, including:

  • Communicate the role of streets in the drainage system. Many residents may not be aware that roads are intended to act as a secondary short-term storage system and/or conveyance pathway for water. This can lead to severe property damage and loss of life when residents do not move property out of harm’s way. For example, recent street flooding has caused severe flooding of cars, which are frequently parked in the street. It is also important to note that 12 inches of water can float a sedan and 18-24 inches can float a larger vehicle, creating hazardous road conditions during extreme events. It is critical to develop a strategy to communicate to the public that streets are designed to be a secondary short-term storage system so that people can take action to prevent loss of property and life. 
  • Address debris in streets and waterways. Maintaining clear openings to storm sewer inlets is a great way to help reduce street flooding. Flooding in many neighborhoods can be made worse by debris and floating trashcans that clog inlets. Additional city, county and MUD maintenance, or organized community efforts may be required. 
  • Ensure that developers have sufficient “upstream” information. Land development engineers typically focus on mitigating the runoff generated by their development project, and as such, flows entering onto their site from other sources may not be considered in their design analysis. Examining strategies to share information about upstream conditions with developers during the design analysis phase could help maximize site-based mitigation. 
  • Maximize on-site retention. Green infrastructure may provide a viable alternative for managing stormwater and reducing nuisance flooding through implementing on-site retention or by providing additional in-line storage capacity within the street (examples include Cottage Grove and Bagby Street). 
  • Identify & target high-risk areas. Determining the neighborhoods most vulnerable to flooding from local drainage challenges would be a pivotal step to targeting public education and mitigation strategies. 

For More Information

The flooding yesterday happened so quickly that it scared people. For many, it brought back vividly the trauma of Harvey and the pain that followed. One person even died when her car ran into a downed tree that fell across Kingwood Drive.

The most damage happened, not to homes, but to vehicles caught in high water on flooded streets – streets DESIGNED to hold water. There’s a simple answer to that. Unfortunately many people did not get the warnings that could have kept them off the streets.

For more information on different types of flooding, see the first part of this FloodWarn Training Seminar that Katie Landry-Guyton of the National Weather Service presented last year at Kingwood College.

Overnight Rains Could Add to This Afternoon’s Woes

A strong line of thunderstorms with high winds, torrential rains and possible tornadoes swept through the Lake Houston area this afternoon. It left widespread power outages, snarled traffic, flooded streets, and swollen creeks and ditches. People still suffering PTSD from Harvey were re-traumatized by the sound of news helicopters and water creeping up their front steps. More heavy rains tonight will add to the area’s woes, even as people are still cleaning up from this afternoon’s flooding.

Examples of Damage Reported

Among the damage reported:

  • Several flooded homes in Bear Branch and Woodland Hills near creeks or ditches
  • Flooded locker rooms at Kingwood High School
  • Trees down and blocking Kingwood Drive at rush hour
  • Power lines down on Kingwood Drive
  • Knee-high water on Kingwood Drive at Town Center
  • Kingwood Drive traffic rerouted up Valley Manor
  • New pad sites for the retail expansion of the HEB center under water
  • Street flooding from one end of Kingwood to the other

Streets Designed as Part of Flood Retention System

Note: the streets in Kingwood are DESIGNED as part of the flood retention system. When rainfall rates exceed what creeks, ditches and bayous can handle, water backs up into streets. and drainage swales.

The amount of rain we received today was not great. But the intensity was off the charts. In about a half hour at my house, we received almost two inches. That’s between 3 and 4 inches per hour. Here’s an example: the swale beside my house.

Valley Manor just north of Kingwood Drive at 4PM on 5.3.19. Two neighbors across the street reports water on their front steps. One said water started to come through her front door. The family is still repairing from Harvey. Her entire family is traumatized.

Rainfall Totals for Friday Storm

Rainfall totals for last 24 hours as of 10PM 5.3.19. Note higher totals upstream from Lake Houston area.

River Report: Minor Flooding Possible on West Fork

Harris County Flood Warning System’s Real Time Inundation Mapping shows most streams within their banks. But note the warning for Humble at US59. While the river is 2 feet below the top of bank as of 10PM, it could easily go out of bank tonight.

More Storms on Way

As of 9PM a severe thunderstorm watch is still in effect for much of southeast Texas until 3PM Saturday.. A large line of strong to severe thunderstorms has developed from E of Austin to NW of San Antonio and is moving ESE/SE at 15-20mph. Expect an average 1-2 inches with the line passage. Isolated total up to 3 inches be common. Creeks and bayous should be able to handle that amount of rainfall, according to Jeff Lindner of Harris County Flood Control.

NOAA forecast clearly shows the line of strong thunderstorms that should hit us overnight.

Here is an updated radar image as of 12:01 AM Saturday morning.

Image courtesy of RadarScope, an amazing app!

Expect minor flooding at 59 and River Grove Park, that could be exacerbated by the mouth bar and other sediment still in the river.

This does not account for any local effects to the mouth bar.

Hoping you stay dry!

Possible Street Flooding Today

Jeff Lindner, Director of Hydrologic Operations and Division Meterologist for Harris County Flood Control, just issued this warning”

“Multiple rounds of thunderstorms with heavy rainfall and some severe weather likely today into tonight.”

“Large cluster of thunderstorms with heavy rainfall extends from near Sealy to College Station and is moving eastward and will overspread much of the region N of I-10 over the next several hours. A second…powerful…bow echo with 70-80mph is rapidly approaching Corpus Christi and the coastal bend and may impact the Matagorda Bay area later this morning.”

“Active pattern will remain in place as several disturbances and a weak cold front move across the area today and tonight and into Saturday. Rounds of thunderstorms will produce heavy rainfall and isolated severe weather. Main severe threats today will be mainly west of I-45 and some of the storms this morning over south-central TX have shown some weak rotation.”

“Expect the current round of storms to move across the area between now and 1-2pm followed by a brief break and then another…potentially stronger round this evening into the overnight period.”

“Rainfall amounts of 1-3 inches will be possible today into early Saturday with isolated higher totals. In fact some of the higher resolution models are showing isolated amounts up to 4-5 inches under training bands today and tonight. Air mass is certainly moist and will be able to support some 1-2 inch per hour rainfall rates which will lead to street flooding.”

River Forecast 

“Area rivers are responding to the recent heavy rainfall and will remain elevated and in flood (Trinity). Additional rains today and tonight and then again next week will only increase rises. The area river and hydro situation is starting to become worrisome given the potential for this pattern to maintain for the next 1-2 weeks.”

What 470 Cubic Yards of Muck Per Hour Looks Like at 1/8000th of a Second

I visited Placement Area 1 this morning . Muck was shooting out of the “diffuser pipe” at 470 cubic yards per hour. That’s enough to fill up 47 dump trucks every hour! A truly impressive sight. So I grabbed my Nikon D5 and started clicking. Only after downloading the images did I realize that I had the shutter set to 1/8000th of a second.

Liquid Looks Like Glass at 1/8000th

Normally, when shooting flowing water, you want to use shutter speeds in the range of 1/8th to 1/60th of a second. Slower speeds blur the liquid and create a sense of motion. The faster speed, however, froze the motion and made the liquid look like glass.

In photography, sometimes mistakes make the shot. This may have been one of those times. As I stared at the effluent, I became transfixed by the thousands of bursting bubbles within it. You can also see how the further the “spray” gets from the pipe, the bursting bubbles begin to reform into smaller droplets.

Effect of Diffusion Pipe

Dredgers call this a diffusion pipe because of those rings on the end of it. They allow the dredger to control the spread of the effluent. By adjusting the spread, they can make it shoot out far like a fire hose or spread out wide.

In this case, they had it set to “wide” so that it would be more controllable.

Diffuser pipe at Placement Area #1 shooting out effluent at 470 cubic yards per minute. Shot with a Nikon D5 at 1/8000th of a second.
A slightly wider shot shows sand piling up. All the water in the effluent finds its way back into the river after sediment drops out of suspension and it is filtered by gravity.
This shot shows three separate activities: a) the pit being filled, b) an excavator moving sand out of the flow, and c) loading a sand truck which will haul it away.

Now Selling Sand from Placement Area #1

A worker told me that early last week, the pit owner started selling sand from the site to an asphalt company. At the present rate, they are hauling it away about half as fast as the pit is being filled. This will help create extra storage area in the pit should the US Army Corps of Engineers choose to use it for the next phase of dredging – the mouth bar.

Max Flow Rates

As impressive as this flow is, I’m told it can go even higher – up to about 1,000 cubic yards per hour. The rate depends on factors such as the density and hardness of the spoils, as well as the distance they are pumped.

Details Still Being Worked Out on Mouth Bar

Still no official word yet on details of Phase 2 – the mouth bar project. The Corps is still evaluating placement areas. It could be that they need to permit more than one to contain the entire mouth bar. However, they also need to move quickly to make sure the dredgers don’t move on to another job.

Because of the lengthy amount of time permitting a placement area can take, the Corps may try to buy time by directing spoils to one or both of the current placement areas which are already permitted.

The more sand that pit owners can sell, the more capacity they will have, and the faster phase two of West Fork dredging can start.

FEMA will not pay to remove the entire mouth bar. FEMA has been working with the Corps and the City of Houston to determine how much of the mouth bar was due to Harvey. By statute, that’s all FEMA can pay to remove.

Variables Complicate Decisions

The City, State and Harris County will have to pay to remove the rest. That’s part of the contingency planning at this point. No details have yet been released about how all the pieces of this jigsaw puzzle will fit together.

Planners are now trying to optimize for at least ten variables that I have heard discussed.

  • Volume due to Harvey
  • Time required to dredge it
  • Available storage in existing placement areas
  • Additional cost to move it to those placement areas (pipe, booster pumps, fuel, etc.)
  • Productivity loss due to additional distance from mouth bar
  • Cost versus amount funded by FEMA
  • Placement areas and cost for any volume FEMA does not fund
  • Time required to permit new placement area(s)
  • Where money will come from to cover what FEMA does not cover
  • When additional funds will be available

Not simple! We can only wish that they could make the decision in 1/8000th of a second.

TCEQ Lists Water-Quality Concerns About Romerica High-Rise Permit

Last week, SWCA, Romerica’s environmental consultant, requested more time to respond to concerns about the proposed high-rise development in Kingwood. On April 30, the Corps withdrew Romerica’s permit application. The Corps suggested that Romerica resubmit a new application once they worked out issues with the first submittal.

Eight Pages of Concerns

All along, Kingwood residents have expressed skepticism about the suitability of this project for the Kingwood location. Turns out the 727 residents and groups that submitted protest letters weren’t the only ones with questions.

The Texas Commission on Environmental Quality’s (TCEQ’s) letter to the Corps expresses eight pages of concerns. Keep in mind that it was dated March 1. So the developer had it for TWO MONTHS. Also remember! TCEQ was reviewing ONLY water-quality issues posed by the development.

Full Text of Letter

Reading the TCEQ letter makes one realize how deficient the original application must have been. Here is the complete text for those who want all the detail.

Summary of Key Points

For everyone else, I have summarized the main concerns below.

  1. Title 30, Texas Administrative Code (TAC), Chapter 279.ll(c)(l), states that “No discharge shall be certified if there is a practicable alternative to the proposed discharge which would have less adverse impact on the aquatic ecosystem, … ” “Please have the applicant clarify the purpose and need for the project, as portions of the proposed project are not aquatic-dependent.”
  2. From the public notice, the applicant states that “they have avoided and minimized environmental impacts by configuring the location of the proposed structures and reducing the size of the lakes within each district.” “This statement does not detail how and where wetland and stream impacts were avoided or minimized. Please have the applicant explain how and where impacts to stream and wetland resources were minimized and avoided.”
  3. “The applicant proposes to develop a mitigation site or purchase credits but says nothing more…The compensatory mitigation plan must include the objectives, site selection, the site protection instrument, baseline information, how the compensatory mitigation will provide required compensation for unavoidable impacts to aquatic resources, a mitigation work plan, maintenance plan, ecological performance standards, monitoring requirements, long-term management plan, adaptive management plan, financial assurances, and other information per the mitigation rule requirements.”
  4. “During the site visit, the resource agencies and the applicant’s representative noticed several streams that were not accounted for in the impacts tables. Please have the applicant incorporate the additional streams and revise the total amount of project impacts accordingly.”
  5. “There are several impacts within the commercial district that appear to be unaccounted for or are unidentified. Please have the applicant revise the impacts table to account for all resources that will be converted.”
  6. “Please have the applicant determine if project specific locations (PSLs) such as borrow, stockpiling, staging, and equipment parking areas associated with the project will impact wetlands. These PSL impacts should be included in the accounting of total project impacts.”
  7. “Several wetlands within the proposed project boundary will be hydrologically disconnected from the current floodplain. Please have the applicant revise the impacts tables to include wetland and stream resources that will be affected secondarily by the proposed project and address the cumulative effect of each district on the interconnectedness of the onsite wetlands.”
  8. “Please have the applicant explain in detail what measures will be taken to avoid groundwater and surface water contamination from construction activities.”
  9. “Please have the applicant provide a hydraulic analysis of the site to account for current site conditions, projected increased impervious surface runoff, as well as drainage patterns for the site, and describe how water quality on and off the project site will be protected from impacts such as erosion.”
  10. “Stormwater drainage from residential and commercial lots should be routed away from the West Fork San Jacinto River, the marina, and stream resources onsite. Stormwater should be redirected and routed to stormwater treatment features before entering the aforementioned resources. Please have the applicant provide details on how the replacement of lost onsite water quality functions will be addressed.”

Other Issues Outlined in Letter

  1. How an expanded Woodland Hills Drive would affect stream crossings
  2. The purpose and design of the so-called “water-quality ponds”
  3. The design of channels and marinas; their connectivity to the San Jacinto; and their impact on water quality
  4. The impact of boat channels on water-oxygen levels
  5. Channels that cross wetland habitat
  6. Box culverts instead of bridges
  7. Channel widths (100-foot wide for a channel 4-feet deep)
  8. Channels crossing property Romerica doesn’t own
  9. Slope of channels
  10. Diversion of stormwater from roads and parking lots away from channels
  11. Dead-end channels
  12. How domestic wastewater will be collected and treated
  13. Dissolved oxygen monitoring and reporting
  14. Applicants characterization of stream types (intermittent vs. perennial); requests “an accurate assessment.”
  15. Conservation easements on the property. (21.90 acres of wetlands are covered by a conservation easement located within the residential and commercial portions of the proposed development. “Please have the applicant verify that the conservation easement will be protected from potential development and ensure the preserved wetlands will not be impacted, directly or indirectly, from the construction of the proposed project.”

Start Over?

There may be no good answers to some of these questions and concerns. SWCA, CivilTech and Romerica must be re-evaluating the impact of these questions on the economics of their project.

This isn’t the type of stuff you need another week to figure out. These questions will make the developers rethink their commitment to the entire project.

Finding answers will likely involve a redesign of the project and that could cost more than the land itself.

Keep in mind that water quality was just one of 20 different areas that the Corps is evaluating.

TCEQ Didn’t Have Enough Info to Make Decision

I asked Peter Schaefer, a team leader within the TCEQ Water Quality Assessment Section, whether the TCEQ had made a recommendation to the Corps on this project. He said “No.”

The reason: “Because TCEQ did not receive a response to our comment letter, and the applicant had not begun the process of working with us and the Corps to address the concerns raised in the letter, TCEQ was not in a position to make a decision on the project,” said Schaeffer. Hence the detailed requests for more information.

Schaefer added, “A typical 404/401 permitting process would normally take several months, if not a year or more, for the applicant to address comments from TCEQ, Corps, resource agencies, and the public. Because of the magnitude and nature of this project, it would likely have required much more time, coordination, discussion, project revision(s), and perhaps additional public notice(s) to get to the point where the Corps was prepared to complete a Decision Document.”
