Dredging of the River Grove Park boat launch and lagoon have been set back at least two weeks. Originally, KSA estimated that the job could finish as early as the end of March. According to KSA President Dee Price, that was an estimate from the contractor, Kayden Industries, not a contract requirement.
Lower Lake Level Required Even Smaller Dredge
According to Price, Kayden ran into a problem when the City unexpectedly lowered the level of Lake Houston about two feet. “The reduction in the water level grounded the dredging barge that they were using,” said Price. “To keep moving forward, they removed the first dredge and brought in a smaller one.”
Original dredge now sidelined. Sand stockpile in parking lot is being removed by truck to a location in Humble out of the floodplain.New dredge is even smaller than last one but can operate in shallower water.About one third of the lagoon in front of the boardwalk remains. Note how vegetation is already regrowing on exposed sediment.This afternoon, the new dredge operated by the discharge pipe.The dredge pumps water and sediment into this giant machine that resembles an oil field “shaker.” It separates solids from liquids.The solids drop out. They are then carried to the edge of the boat dock where they dry further before being hauled off.Water minus sediment over a certain size is then returned to the river.
Contractor Will Finish Job With Smaller Dredge
“The water level is back up now,” said Price. “Kayden thinks they can finish the job using the smaller dredge, but it will take a little longer.”
With the corona virus restrictions, there is now very little activity at the park. Reminder: children should NOT use the playground equipment to help restrict the spread of the virus. Soccer leagues have also been affected. Only a handful of people were using the park this afternoon.
After Dredging
The sand pile is still blocking the boat launch. It and Kayden’s equipment will be removed from the park when dredging completes in a couple more weeks.
At that point, KSA intends to repair the asphalt damage from the heavy equipment. KSA will also replace the speed bumps with speed humps to accommodate boat trailers. All that could take till May.

On March 16, 2020, the Texas Water Development Board (TWDB) finally started accepting applications for flood infrastructure projects under Senate Bill 7 signed by the Governor on June 13, 2019. We’re now at 941 days since Hurricane Harvey.
What Took So Long
What took so long?
Harvey happened shortly after the 2017 legislature concluded.
The Governor would immediately release money from the Rainy Day Fund.
The next legislature met in January of 2019.
It took until the end of May, 2019 for SB7 to work it’s way through the Senate and House.
The Governor signed the bill in June.
The bill stipulated that the fund had to be approved to voters in November 2019. It was.
With construction on many projects taking a year or more, the earliest citizens may see benefits from many of these grants will be 4 years post Harvey.

A friend, Dr. Matthew Berg, CEO and Principal Scientist of Simfero Consultants, observed that flooding and the corona virus are alike. The more I thought about that, the more intrigued I became. Controlling both requires similar strategies.
Controlling Convergence is Key
Of course, when looking at the corona virus, it spreads from “one-to-many.” And when looking at flooding, the relationship is reversed, “many-to-one.” But stay with me for a moment. Because similarities will become apparent at the point of convergence.
Dozens of creeks and streams flow into Lake Houston from approximately 2,600 square miles.
Creeks and streams from 2,600 square miles converge on Lake Houston during heavy rains. That can cause flooding. Likewise, thousands of corona virus victims could soon flood the area’s limited number of hospitals.
Harvard Study Shows Hospitals Rapidly Becoming Overwhelmed
Last week, ProPublic published an article, “Are Hospitals Near Me Ready for Coronavirus? Here Are Nine Different Scenarios.” The article is about a Harvard Global Health Institute study. It modeled different rates for the spread of the virus: 20%, 40% and 60% of the population infected over 6, 12 and 18 months. The authors then compared results against the number of available hospital beds in various areas.
Interestingly, they used the Houston region as their first test case. In only one of the nine scenarios, did we have enough hospital beds to handle the flood of corona victims. That scenario was for 20% infected (the smallest percentage) over 18 months (the longest period).
Darkest blue represents 6-month peak, middle blue a 12-month peak, and lightest an 18-month peak.
In the graph above, the areas shaded with crosshatching represent the normal baseline level of bed occupancy for non-corona patients in Houston hospitals. The colored areas represent the percentage of the area’s population projected to seek admission within a 6-, 12- or 18-month period.
2.8X Available Hospital Beds
The ProPublica article about the Harvard study goes into much more detail. It looks at all 50 states, the number of ICU beds, available ventilators, people etc.
In Houston, the researchers found, “The influx of patients would require 14,300 beds over 12 months, which is 2.8 times the available beds in that time period. The Harvard researchers’ scenarios assume that each coronavirus patient will require 12 days of hospital care on average, based on data from China.”
ProPublica Article on Harvard Study
One hospital administrator said, ““The reality is that you can’t create unlimited hospital beds and ventilators. We have what we have, so we really have to hope that it’s enough, and that we’re prepared enough.”
Flattening the Curve Prevents Avoidable Deaths
Said the authors, “By modeling the data over the three time periods, the scenarios illustrate how much the nation could “flatten the curve” with social measures to ensure hospitals have greater capacity to care for coronavirus patients.”
Epidemiologist Dr. Marc Lipsitch, head of the Harvard T.H. Chan School of Public Health’s Center for Communicable Disease Dynamics said, “The way to permanently stop new cases from setting off long chains of transmission is to have each case infect considerably less than one case on average. The numbers will go down. There will still be little outbreaks, but not big ones.”
Basically, Dr. Lipsitch argues that controlling the flood of victims early at the source is the only way to avoid overwhelming health care resources.
This YouTube video from Vox about Avoidable Deaths shows how slowing things down and flattening the curve helps everyone.
It’s much the same in physical flooding. Too much water in too little time overwhelms the available capacity of streams, rivers and lakes. Property is destroyed. People die.
The beat the peak loophole in MoCo regulations says that if developers can prove they can get their runoff to the river before the peak of a flood, they don’t have to build detention ponds. That’s what happened in the 2200-acre Artavia development. Of course, this incentivizes developers to get their water to the river ASAP.
And that’s exactly the opposite of what you need to protect lives and property downstream.
It’s kind of like saying, “Let’s infect everybody as fast as we can.”
Slowing down the spread of the virus will give researchers time to develop a vaccine or for the population to develop herd immunity … before hospitals become overwhelmed.
Unfortunately, there is no vaccine or herd immunity to protect downstream residents from greed. And there never will be. That’s why we need to close the “beat the peak” loophole before it’s too late.

What Took So Long
What took so long?
We Aren’t to Goal Line Yet
What happens next?
Construction of projects can then begin. If they were construction projects. Some grants will cover planning activities such as:
Different Types of Projects Eligible
The Flood Infrastructure Fund established by SB7 provides grants and 0% loans totaling $793 million. Eligible projects fall into four categories.
Here’s a 36-minute video that explains the incredibly complicated rules for distribution of the funds. Warning: the video is not geared toward the public, but toward City and County employees who will apply for grants. Nevertheless, it’s interesting to see what goes on behind the scenes. Here’s a printed version of the Flood Infrastructure Fund Intended Use Plan that also describes all the rules.
Need to Move Quickly
With construction on many projects taking a year or more, the earliest citizens may see benefits from many of these grants will be 4 years post Harvey.
I understand the need to be cautious when handing out close to a billion dollars. But I also feel the need to act quickly with yet another hurricane season boring down on us. We should not forget that just last September, the fourth wettest storm in US history, Imelda, wiped out large areas between Houston and Beaumont. Sixty-two percent of the homes flooded during Imelda were outside of the 100-year floodplain. So we have lots of room for improvement.

Parallel With Physical Flooding
It’s much the same in physical flooding. Too much water in too little time overwhelms the available capacity of streams, rivers and lakes. Property is destroyed. People die.
That’s why flood experts argue for upstream detention. This post about closing the detention pond loophole in Montgomery County flood regulations contains two FEMA case studies from Texas about the value of detention ponds. Slowing water down prevented flooding.
The beat the peak loophole in MoCo regulations says that if developers can prove they can get their runoff to the river before the peak of a flood, they don’t have to build detention ponds. That’s what happened in the 2200-acre Artavia development. Of course, this incentivizes developers to get their water to the river ASAP.
