The Valley Ranch area in Porter near US 59 and SH 99 is developing rapidly these days. Signorelli Company calls Montgomery County the 18th fastest growing county in the US.
Medical Plaza Site Cleared
The developer has just cleared a 200+ acre site for a medical plaza in this area. Signorelli’s website says, “Envisioned as the ‘place of wellness’ for the region, the Medical District is a visionary mixed-use concept blending healthcare with restaurants, specialty services, hotels, and high-density residential, providing a broad range of health care services, from primary physicians to acute care and every specialist in between.”

Detention ponds, both in this picture and the developer’s website seem to be planned for the area back from the freeway.Photo taken 5/3/2021.
The Montgomery County Engineer’s office says it does not yet have construction, drainage plans, or an H&H analysis specifically for the medical plaza property. In response to my FOIA Request, the engineer’s office said, “This is all we have on file at this time.” Their drainage mitigation study they sent me was produced in 2014, long before Atlas 14. That means its runoff calculations are likely 40% short of the current standard. The study also does not isolate this portion of the overall development.
It’s unclear at this time whether Signorelli is planning to update its drainage mitigation study and incorporate Atlas-14 standards into its medical plaza drainage.
Amazon Distribution Complex Across Freeway
Right across the freeway from the Valley Ranch medical plaza, Amazon is building a distribution complex.
That green area that snakes its way across 99 and then 59 from the top left to upper right is White Oak Creek. White Oak runs southeast through Porter then joins Taylor Gully and Mills Branch south of the Triple PG Sand Mine near Woodstream Forest. Ultimately, it joins Caney Creek near Dunnam Place and then the East Fork of the San Jacinto. See below.

Today marks the 1349th day since Hurricane Harvey. That’s also how long it took the United States to win World War II. To date, we’ve studied problems, made bold plans and, in a few cases, actually started constructing flood mitigation projects. But none of the $2.1 billion allocated for Texas flood mitigation by the US Department of Housing and Urban Development (HUD) has yet to work its way down to the local level.

In the time it took us to win World War II, we’re still trying to line up flood mitigation financing.
Imagine What That HUD Money Could Have Done By Now
The Texas General Land Office (GLO) administers HUD flood mitigation funds for Texas. However, it has yet to announce the results of a statewide grant application competition for the first half of that $2.1 billion. Hopefully, those announcements will come this month. The GLO intends to hold a second competition for the second half of the money at a later date.
Below are thoughts contributed by others. To encourage their candor, I promised them anonymity.
I. Consolidation Under One Agency
One federal official suggested that all flood mitigation funds should flow from the Federal Emergency Management Agency (FEMA), not HUD.
Rationale: Disaster relief is FEMA’s core competency. FEMA’s good at it. FEMA responds quickly. They are on location after disasters. They collect immense amounts of data, manage the National Flood Insurance Program, and have resources to get the job done quickly.
Right now, HUD, the slowest agency with the most rules and regulations, is responsible for helping the poorest neighborhoods, i.e., those that often need it most. Many think that’s unfair.
Dividing responsibilities among agencies creates needless bureaucracy, complexity, overlap and “stove piping.”
Stove-piping is where people in one bureaucracy are blind to activities in another. Eliminating the stove-piping requires cross checking data between agencies and programs, for instance to eliminate duplication of benefits. But that can also slow projects down.
Rationale: Not all earmarks are meritless. In cases of exceptional need, they can send money directly to cities or counties trying to build important flood mitigation projects. With proper safeguards against bogus earmarks, this idea could shave years off construction projects designed to protect people.
III. Partner with Army Corps More
Another expert suggested directing more money to the Army Corps for “project partnership agreements.” The Corps work directly with a local entity such as a city or county to help construct projects faster.
Rationale: The Corps was originally set up more than 200 years ago as a quick-reaction force for wartime. It now has the responsibility for managing the nation’s water infrastructure. The Corps has the turnkey expertise to gauge the merit of projects and the muscle to make things happen quickly.
Previously, the Corps built the Antoine Stormwater Detention Basin in the Greens Bayou Watershed. HCFCD bought out the properties that comprised that basin and currently maintains the property.
IV. Establish a “Quick Reaction Fund”
A financial expert suggested establishing a “Quick Reaction Fund.” It would be activated by a Presidential Disaster Declaration and provide loans to get projects started quickly. The money could be used to jumpstart upfront activities, such as buyouts, environmental surveys and preliminary engineering reports. It could also be used to build entire projects that are needed quickly.
Rationale: Local entities often don’t have the money or staff to conduct these upfront activities. Buyouts can be especially problematic. They must often be completed before other flood mitigation activities, such as ditch improvements or detention ponds, can start.
“But we often have to wait 18 months or more for approval of buyouts,” said one engineer. “The vast majority of people can’t wait that long.”
So they fix up their homes and become more committed to them. Or they may just leave the area. Either way, this slows flood mitigation down even more.

Many residents left the area because they got tired of waiting for buyouts that are still not complete. That makes buyouts even more time consuming. Photo taken May 3, 2021.
The Quick Reaction Fund could help complete buyouts in months – instead of years – after a flood.
Loans could be paid back later by grant awards from the Feds.
V. Pass a Hazard Tax
To bypass the delays and uncertainties of competitive grant funding through state and federal levels, one local entity suggested passing a “hazard tax.”
Rationale: This would put local entities in charge of their own destinies rather than making them dependent on Washington and Austin for handouts. It would let cities and counties build up a war chest from their own tax revenues. Think of it as a savings account with a dedicated purpose – disaster mitigation. The money could be used to fund projects directly and quickly, or as the basis for matching funds when projects are less time critical.
In my opinion, we desperately need a way to resolve such issues faster. I hope this series of articles will start a public dialogue among political leaders at all levels.

1349 Days after Hurricane Harvey, the number of days in WWII
https://i0.wp.com/reduceflooding.com/wp-content/uploads/2021/05/TS-Harvey-8-30-17-209.jpg?fit=1024%2C768&ssl=17681024adminadmin2021-05-09 14:24:502021-05-09 19:15:39How to Speed Up Flood Mitigation Funding: Part II
As June 1st rapidly approaches, Texas coastal communities are wondering what the 2021 Hurricane Season will hold. Will thousands of Texas families be spared, or will they endure hurricane-force winds and flooding with years of recovery ahead of them?

We cannot stop natural disasters from happening, but we can certainly speed recovery efforts. The Texas General Land Office (GLO) has administered recovery programs for seven of the 18 major declared disasters the State of Texas has experienced in the last 15 years. We know firsthand how exhausting and lengthy this process can be. After flood waters have abated and the debris has been cleared, communities face the next hurdle – navigating the arduous and overly burdensome bureaucracy shackling speedy recovery efforts.
Cutting Red Tape
My GLO team and I recognize the importance of following procedures to safeguard federal funds, but also understand bureaucracy is an obstruction to recovery and mitigation. Community Development Block Grants for Disaster Recovery (CDBG-DR) appropriated by the U.S. Department of Housing and Urban Development (HUD) take years to reach disaster survivors. One of the most frequent concerns we hear—from survivors, county and local officials, and other stakeholders—is that CDBG-DR funds do not flow quickly enough to communities in need.
These dollars should be deployed as quickly and flexibly as possible to support recovery with as few additional regulations as possible.
First, we must ensure effective and efficient disaster recovery by providing the framework for programs and activities that provide disaster relief; resiliency; long-term recovery; restoration of infrastructure and housing; economic revitalization; and mitigation in areas impacted by Presidentially declared disasters. This begins with codification of CDBG-DR program rules and regulations.
Reducing Upfront Delays
For every new allocation, a new series of rules are written and published in the Federal Register. In Texas we are currently implementing CDBG supplemental funding for 8 events governed by 22 separate Federal Registers (rule books for how funding allocations may be used). A good amount of those rules, such as the national objectives imposed and the range of eligible activities, remain largely the same each time, but others are entirely new. Based on our experience, it takes between nine to sixteen months for a Federal Register Notice to be published for allocations of recovery funding after the major disaster declaration takes place. These allocations must first be granted to a state or other grantee following a special appropriation from Congress.
The Federal Register for the CDBG-MIT funds was posted two years to the day after Hurricane Harvey made its final landfall on the coast of western Louisiana.
Inspector General Recommends Codifying Rules
HUD going back to the drawing board for each appropriation consumes critical time that could be spent setting up programs at the state and local levels if the rules were codified. In July 2018, the HUD Office of Inspector General (HUD OIG) issued a report that identified 59 common rules HUD issues when drafting Federal Registers. The same report recommended HUD work to codify the CDBG-DR program.
Fund deployment speed can also be enhanced by:
Streamlining processes at the federal level and at HUD
Retaining and developing in-house knowledge
Empowering grantees to move with a purpose.
Five Specific Recommendations to Expedite Process
There are several steps the federal government can take to expedite this process. Here are the five I consider to be the most impactful:
Create Office of Disaster Relief and Recovery – HUD currently has several offices with jurisdiction over CDBG-DR funds. This creates a tangled web of bureaucracy when HUD drafts a Federal Register, approves an Action Plan, or a grantee must seek a waiver or other change to program, vastly delaying the distribution of funds. A distinct disaster recovery division headed by an Assistant Secretary with discretion over disaster recovery funds would limit stove-piped information, reduce redundancies, and expedite decision-making authority within HUD. This change alone would vastly reduce delays in program progress.
Facilitate capacity building – HUD should provide grantees an initial amount of administrative funds prior to approval of the action plan and grant agreement. This would enable grantees to hire staff to provide technical assistance for drafting the action plan and begin to build programs while the action plan is being developed so recovery efforts would not be delayed 6+ months while the process concludes. Many grantees lack the resources to essentially operate on credit until these funds are made available.
Standardize programs and only post changes – Congress should pass legislation standardizing rules so the Federal Register only includes what you cannot do versus everything you can. This would lessen the time waiting for the rules to be written and allow grantees to begin working on the general premise of what the program cannot do.
Codify data coordination between FEMA and HUD – The federal government must build a capable national data system to coordinate data sharing between federal, state, and local agencies. FEMA collects a tremendous amount of data following every disaster. This data is used to inform HUD allocations as well as to develop needs assessments by grantees. However, there is not a system in place that enables this data sharing to happen quickly, safely and effectively.
Codify allocation timeline – HUD is not currently restricted in how long it takes to allocate special appropriations of CDBG-DR and CDBG-Mitigation to grantees. Additionally, grantees cannot begin drafting hundreds of pages of state and local action plans until HUD issues the rules for use of funds in the Federal Register.
Example of Delays in Current System
For example, Congress appropriated nearly $28 billion to help disaster-affected states rebuild on February 9, 2018. Two months later, HUD allocated $4.383 billion to Texas. At the time, HUD also stated it “will issue administrative guidelines shortly for use of the funds to address grantees’ long-term recovery needs.” However, this did not happen for nearly a year and a half.
On August 30, 2019, HUD finallypublished the Federal Register notice enabling the State of Texas to proceed in drafting an action plan for the CDBG-MIT funds. The Federal Register required a robust public outreach component. The GLO went above and beyond HUD’s mandates by extending the required 45-day public-comment period to 50 days and surpassed HUD requirements by hosting eight public hearings – three public hearings prior to the completion of the draft plan and five following publication of the draft plan. Prior to finalizing the draft of the action plan, the GLO responded to thousands of comments collected from 117 meetings and 936 individuals.
While the GLO waited 16 months for rules for the action plan, it only took the GLO approximately five months to draft the nearly 500 page document, conduct a historic public outreach effort, respond to comments, make revisions, and submit the plan to HUD for approval. It then took nearly two months before the GLO received approval from HUD.
The turnaround time for announcing rules should be substantially reduced to expedite the use of disaster recovery funding for those in urgent need of assistance.
Since 2011, the GLO has worked with hundreds of communities and several thousand families to repair homes; reimburse out-of-pocket home repairs; conduct buyouts and acquire flood-prone properties; strengthen infrastructure; and conduct major planning studies to support local government mitigation efforts. The success of our programs can be attributed in part to our staff of dedicated experts as well as our streamlined grant administration.
No additional regulations or rules are added to our programs beyond what the federal government requires.
George P. Bush
The GLO has proven that you can expedite recovery by eliminating unnecessary regulations, pre-positioning resources and putting contracts in place before a disaster. Disaster survivors shouldn’t have to wait years for assistance. It is plain and simple – we can and should lessen the burden on families and communities by reducing redundancies and implementing common-sense reforms.

1348 Days after Hurricane Harvey

Sunday, May 9th will mark a special day in the history of flood mitigation. We will have spent more time responding to Hurricane Harvey – and accomplishing little – than it took us to win World War II. December 7, 1941 to VJ Day on August 15, 1945 was 1349 days. On May 9, 2021, it will have been 1349 days since Hurricane Harvey ravaged Texas and the Gulf Coast.

What Happened to American Determination and Unity?
After Harvey, we stood united in a sense of grief, loss and determination. We vowed to implement measures that would make us more resilient against such storms in the future.
In the Lake Houston Area, we had a three part mitigation strategy:
More upstream detention to help offset future releases from Lake Conroe.
Dredging to eliminate blockages in the rivers.
Additional flood gates on Lake Houston so we can shed water as fast as Lake Conroe sends it downstream.
We just finished a preliminary engineering study to add more flood gates to the Lake Houston dam. The second phase of the engineering study is just starting. The City hopes to finish it by September 2022 – five years after Harvey.
We’re still waiting to hear aboutgrants to study sedimentation; joint reservoir operations for Lakes Conroe and Houston; and more.
We’re still fighting with each other over which neighborhood gets its flood mitigation projects started first.
Upstream officials still turn a blind eye to violations of their own flood regulations designed to protect public safety…in order to attract new development.
The winners of a HUD Hazard Mitigation Grant competition for Hurricane Harvey have yet to be announced.
And the vast majority of money appropriated by Congress for Hurricane Harvey relief in February of 2018 has yet to work its way down to the local level.
We Need More Emphasis on Action
Imagine if we had still been studying an appropriate response to Pearl Harbor after 1349 Days. Somehow, we’ve confused studying problems with fixing them. Thought has become disconnected from action, or worse, substituted for it. This is not America’s finest hour.
It’s not that we can’t mitigate flooding problems. It’s that we’re not organized to do so in a timely way. We study these things endlessly. We value perfection more than protection.
We have compounded a natural disaster with:
“Paralysis through analysis”
Divided responses on the federal, state and local levels that have no central coordinator
Contradictory priorities between upstream and downstream interests
Complex, often contradictory, organizational requirements.
We CAN Be the Solution
We need to re-engineer business processes to focus on what matters:
Helping people rebuild their homes, businesses and infrastructure…
And reducing the risk of future disasters…
In the least amount of time possible.
That’s it. It’s that simple. The first two are clear statements of intent to unify purpose. And the third is a simple goal by which everyone involved can measure individual efforts.
In the coming days, I will publish a series of articles on how to streamline the business processes built up around flood mitigation and disaster relief. One will be authored by George P. Bush, the state’s highest disaster relief official. And another will be anonymous to allow several people to speak freely and frankly.
My goal is to stimulate a public dialog that can help us get closer to the goals listed above.

1347 Days since Hurricane Harvey
https://i0.wp.com/reduceflooding.com/wp-content/uploads/2021/05/20210507-Arizona.jpg?fit=1200%2C801&ssl=18011200adminadmin2021-05-07 14:33:182021-05-12 15:17:20It’s Official: Harvey Flood Mitigation Is Taking Longer than World War II
The project should help alleviate flooding in Kingwood subdivisions such as Elm Grove, North Kingwood Forest, Mills Branch and Woodstream Forest. Residents in each village experienced disastrous flooding, not once, but twice in 2019. Widening and deepening the gully will increase its conveyance and take more than 400 homes out of harm’s way.
Connected Issues
However, the increased conveyance could also create the need for more more detention capacity to reduce the risk of flooding elsewhere.
This graph of Brays Bayou during the last century shows how runoff accelerates with development. Instead of floodwaters being stored in wetlands and forests, storm drains rush the water to the bayou. That results in higher, faster rises during storms.
Rapid upstream development has put pressure that never existed before on downstream homes. That development decreases the time of accumulation for floodwaters. Without more detention ponds to hold some water back, widening, deepening Taylor Gully could solve a problem in one place and create a problem in another. It could result in faster, higher flood peaks downstream.
Woodridge Village Could Be Part of Taylor Gully Solution
Thanks to the TWDB, the bulk of construction money is now committed to the project through the City of Houston. That means the lead partner on this project, HCFCD, can tell its engineering contractor to accelerate planning.
Development of such projects is often like a dance between political and project leadership. Neither side can get out of step with the other for long.
At this hour, many details have yet to be worked out on the engineering and cost estimating side. But some of the political and funding clouds are parting enough to see a clear path to completion. However, one thing is perfectly clear.
As watersheds develop, it’s important to set aside room for detention pond capacity. Once a watershed is fully developed, homes and businesses must be bought out to create those ponds.

In the continuing saga of the Woodridge Village fiasco, lawyers Jason Webster and Kimberley Spurlock have filed a new lawsuit on behalf of approximately 50 Porter residents who flooded on May 7th and/or September 19th in 2019. Webster and Spurlock previously filed lawsuits on behalf of Elm Grove and North Kingwood Forest residents who flooded on those same days.
Beating Statute of Limitations
Webster and Spurlock filed the new suit on May 5th, 2021. Normally, a two-year statute of limitations applies in such cases, according to one lawyer I talked to. So these plaintiffs just beat the deadline.
Contractors built Woodridge Village (right) up about 3 feet relative neighbors (left) without providing a path for water to drain. Note ponding water on left where plaintiff Chris Yates lives.Photo courtesy of Yates.
Legal Basis for Claims
Defendants allege that the proximate cause of flooding to their homes was an illegal impoundment of surface water caused by defective construction practices. They cite Section 11.086 of the Texas Water Code. It states that “No person may divert or impound the natural flow of surface waters in this state, or permit a diversion or impounding by him to continue, in a manner that damages the property of another by the overflow of the water diverted or impounded.”
In relation to the alleged “defective construction practices, plaintiffs claim “Negligence, Negligent Retention, Negligent Supervision, Negligence Per Se, and Gross Negligence for the May 7, 2019 floods.” Pages 14 and 15 of their complaint claim 34 separate failures.
Plaintiffs also claim Negligence, Negligence Per Se and Gross Negligence against the developer defendants for the September 19th flood. In regard to those claims, they list 29 separate failures relating to inadequate construction.
Plaintiffs further allege defendants created a nuisance and “trespassed” on their property. From a legal point of view, trespass includes “causing something to enter another’s property.” In this case, the something was water.
List of Defendants
Defendants in the lawsuit include the developers, engineering company and contractors. They include:
Perry Homes, LLC (developer)
Figure Four Partners, LTD (a Perry Subsidiary)
PSWA, Inc. (another Perry Subsidiary)
LJA Engineering Inc.
Rebel Contractors, Inc.
Double Oak Construction, Inc.
Texasite, LLC
Concourse Development, LLC
LJA Played Central Role
LJA played a central role in the flooding. Perry and its subsidiaries hired LJA to engineer the development and help supervise contractors to ensure they were working to plan. Plaintiffs allege LJA:
Failed to follow the correct drainage guidelines for Montgomery County
Failed to enforce the construction schedule
Failed to provide adequate drainage
Failed to adequately model the development
Removed drainage channels
Caused water elevations to increase downstream
Failed to design adequate detention ponds
Failed to use the correct hydrology method
Failed to design emergency overflows
Failed to comply with the soil report produced by Terracon Consultants, Inc.
Failed to protect water runoff from flooding Plaintiff’s homes
Violated the contractors duty and standard of care.
Plaintiffs Seeking Compensation For…
Plaintiffs seek compensation for damages including:
Cost of repairs
Cost of replacement or fair market value of personal property lost, damaged, or destroyed
Loss of use of personal property
Loss of income and business income
Consequential costs incurred such as hotel accommodations and replacement costs
Mental anguish and/or emotional distress
Prejudgment interest
Post judgment interest
Attorneys’ fees
Court costs
Exemplary and punitive damages
Finally, the plaintiffs seek a jury trial to decide issues of fact in the case.

In its May 6 board meeting tomorrow, the Texas Water Development Board will vote on whether to approve financial assistance from the Texas Flood Infrastructure Fund to widen and deepen Taylor Gully. That would increase the “level of service” from 10 to 100 years.
The channel would then be able to handle a 100-year rain without flooding instead of just a 10-year rain as it does now. And that would benefit more than 400 homes.
To put a ten-year rainfall into perspective, the eight inches received in two days last week by areas northwest of Lake Houston qualified as a ten-year year event. Luckily, the rain that fell over the Taylor Gully watershed only qualified as a 1- to 2-year rain.
Taylor Gully is the channel below Woodridge Village that experienced disastrous flooding twice in 2019 on May 7th and September 19th (during Imelda).
Explanation of Partnerships and Financing
The City of Houston has requested a $10.1 million loan for construction of the Taylor Gully project. The financial assistance that the TWDB will vote on would take the form of a purchase of City of Houston bonds.
Harris County Flood Control District (HCFCD) would lead the project all the way through construction. The Flood Control District (and hopefully, federal money) will provide the balance of project funds up to $20.2 million out of Bond Project ID F-14 and a Community Project Funding request by US Congressman Dan Crenshaw.
The project will require a considerable amount of upfront work that includes engineering, design, surveying, geotechnical work, environmental permitting and more. The project won’t be ready for actual construction for at least a year. And the City cannot tap into a construction loan until construction starts.
Therefore, the Harris County Flood Control District (HCFCD) will use County money to cover those upfront costs, according to Alan Black, Director of Operations for HCFCD. Some land acquisition may also be necessary, though that has not been fully investigated yet.
Congressman Dan Crenshaw has requested federal dollars to help supplement HCFCD funds for the Taylor Gully and Kingwood Diversion Ditch improvements identified in the Kingwood Area Drainage Analysis. Federal dollars could help stretch local dollars to help develop more projects. (See below about Cypress Creek projects.)
Crucial TWDB to Vote Tomorrow
But everything hinges on the City’s application for a loan from the Texas Flood Infrastructure fund. The City’s request will be #6 on the TWDB meeting agenda. Here is the packet for the board that explains the proposal. It includes cost breakdowns and a timetable, which will likely be accelerated according to project insiders.
The TWDB staff has recommended that the board approve the project.
TWDB
The Taylor Gully watershed currently has a 10-year level of service because the area upstream has undergone significant development with limited flood mitigation or detention.
Elm Grove debris pile from Imelda flood. This is one of hundreds of homes that flooded near Taylor Gully.
The proposed project includes improvements along the Taylor Gully channel to upgrade the conveyance capacity to provide a 100-year level of service. The improvements include channel widening, deepening, and lining. The project will benefit more than 400 structures. 387 will see direct benefit during 100-year inundations. An additional 62 structures benefit indirectly.
How to Attend the TWDB Meeting
The Texas Water Development Board (TWDB) meeting to consider approving financial assistance for Flood Infrastructure Fund projects will be held on Thursday, May 6, at 9:30 a.m. There are two ways that the public and interested stakeholders may attend the Board meeting:
State Senator Brandon Creighton sponsored the bill that created the state’s Flood Infrastructure Fund in the 2019 legislature. This link tracks expenditures from the Flood Infrastructure Fund. To date, the TWDB has committed almost $200 million from the fund.
The TWDB has recognized the importance of the project. The City of Houston is putting up the lion’s share of the money for the project. HCFCD is fronting the upfront costs and half of construction dollars. And Congressman Dan Crenshaw is helping to stretch local dollars by supplementing them with federal funds.
HCFCD, Crenshaw Also Working on Cypress Creek Improvements
Crenshaw’s funding request would also help fund the Westador and TC Jester Detention Basins on Cypress Creek. Those are two large basins being planned by HCFCD. Together they would hold about 1,600 acre-feet of stormwater.
To put that in perspective, 1,600 acre feet is enough to contain a foot of rain falling over 2.4 square miles. That could provide benefits both upstream and down. More news to follow on those projects.

Yesterday, I wrote how the San Jacinto East Fork seemed to have re-routed itself through an abandoned sand mine. This morning I got a call from a couple who live near the mine. The woman and her husband had been trapped in their home for three days by the river which is now – incredibly – running right beneath their home. As of 5 p.m. Tuesday, floodwaters subsided enough for them to boat to safety. But their story is a gripping lesson in how quickly life can change.
Dream Turned into Nightmare
Jack Arnold bought 25 acres in the country back in 2002 to have a retreat from the noise of the city. He works in structural steel and quiet Plum Grove in Liberty County seemed like the perfect place to unwind. He and his sons built a home in 2011 on steel poles 21 feet in the air about 400 feet east of the San Jacinto East Fork.
The spot Arnold cleared for his home in 2011, east of the East Fork San Jacinto which runs through the woods to the left of the red box.
Then three things happened.
In 2012, a sand mine started up about 1100 feet south of him.
Later that year, Colony Ridge started building northeast of him.
His ex-wife sold 16.5 acres of their property to the sand mine, which then expanded around him.
It didn’t take long for Arnold’s flooding woes to start.
Sand Mine and Colony Ridge Permanently Alter Hydrology of Area
Here’s what the surrounding area looks like today.
FEMA’s National Flood Hazard Layer Viewer shows that the sand mine’s dikes have constricted the East Fork floodway (cross-hatched area) about 90%. This puts tremendous pressure on the mine’s dikes as water tries to squeeze through a fraction of the space. That also increases erosion which further breaks down the dikes.The constrictions could be one reason why the river rose 10 feet in 24 hours at this location.
Arnold says his property never flooded in the first five years he lived there. Then in 2015, as Colony Ridge and the sand mine expanded around him, he started flooding regularly. Last Sunday, the water started rising again. This time, it was from an 8-inch rain that areas upstream received. Plum Grove itself received only a little more than 3 inches. Harris County’s meteorologist characterized the 8-inch rain, which fell over a two-day period, as a ten-year rain.
Near Death Experience, Not to Mention…
As floodwater rose around the Arnolds last Sunday morning, they had a hard time understanding why. But it kept coming up and up. Three days later, it’s still four-feet deep (waist high) under their house and moving so fast it could knock strong men over.
Arnold nearly died in a previous flood event when he was swept away. He clung to a tree for two hours until his second wife and stepdaughter rescued him. Then all three had to be rescued by the game warden three days later. Now, Arnold takes no chances. He and his wife have been holed up alone for three days waiting for the water to go down. They each have missed two days of work so far this week, because they couldn’t reach their cars which they parked on higher ground.
Altogether, they have lost nine vehicles, two campers, and a boat since the flooding started. Another reason they were reluctant to leave their home despite being trapped: looters stole all their valuables after they evacuated during a previous flood.
Begging For a Buyout that Hasn’t Yet Come As Flooding Gets Worse
The Arnolds don’t want to move; after all, Arnold built the home with his own hands. But he and his wife just can’t take any more flooding. Now, they just want out. They’re begging for a buyout that hasn’t yet come.
Perhaps worse, the sand mine has been sold to a company that wants to turn it into an RV park. Which means there’s no one to fix the dikes which ruptured during the latest flood. In a phenomenon that geologists call pit capture (or river capture), the East Fork rerouted itself through the sand mine and then filled the mine up like a water balloon. The water balloon then broke more dikes on the southern end of the mine in a location that is not aligned with the bridge openings over the East Fork.
The main current of the river has been running through the mine and under the Arnolds’ home for days now.
House Built in the New River Bed?
Now the Arnolds worry they may have a house built in the river. Of course, they won’t know until the flood water goes down. And even though the water level has lessened slightly since yesterday, it is still too high and too dangerous to venture out. See images below.
Looking SE. Sand mine dikes have broken on the lower right and now water rushes out of the west fork, crosses the mine and goes under Arnolds’ house in the trees on the left.
Looking NW. Note how the pressure of the water has collapsed the swimming pool in their side yard.
Looking NW.The water then rushes back into the mine from the south side of the property.

As of Monday morning, the threat to Lake Conroe had passed, but now floodwaters from the rain soaked northwestern portion of the region are converging on Lake Houston. Here’s a roundup of what’s happening where.
Lake Conroe Going Down
The San Jacinto River Authority reduced its discharge rate to from 9275 cubic feet per second (CFS) to 8120 CFS as the level of Lake Conroe continued to recede, but the West Fork came out of its banks at US 59. The West Fork also began flooding Kingwood’s River Grove Park and the abandoned Noxxe Oil Fields between the river and the Forest Cove Little League Fields.
As of 5:09 pm on 5/3/2021
Lake Conroe Re-Opening With Caution
The SJRA issued a press release at 10:15 am. stating that Lake Conroe will reopen to normal lake traffic at noon Monday, May 3. However, boaters are still urged to use extreme caution due to floating debris and submerged objects that may not be fully visible. With submerged bulkheads, lake area residents should also be cautious of electrical outlets and equipment coming into contact with water.
SJRA is currently releasing water from the Lake Conroe dam to gradually lower the water level back to conservation pool of 201’, but SJRA must strike a balance between upstream recovery and downstream danger. For real-time information on Lake Conroe levels, releases, rainfall totals, or stream flows visit www.sjra.net.
SJRA clarified that it intends to return Lake Conroe to 200 until June 1 per its seasonal lake lowering policy as soon as emergency operations restore it to 201. Normally, SJRA would begin recapture on June 1, not May 1. The seasonal release rate is much lower than the current rate.
Floodwaters Converging Toward South and East
Meanwhile, the glut of rainfall that inundated the northwest portions of Houston last week is starting to converging on areas downstream.
As of 10:30 am, the San Jacinto East Fork is also way out of its banks at FM1485 and FM1485 is reportedly closed until Friday. That leaves one way in and out of Colony Ridge – FM2090.
The San Jacinto East Fork at FM2090 peaked overnight and is starting to recede, but is still out of its banks. The East Fork is not influenced by the Lake Conroe Dam, which is on the West Fork.
FM2090 at East Fork near Plum Grove on May 3, 2021 at noon.
FM2090 is still open, but Plum Grove resident Michael Shrader reported a steady line of traffic trying to get out of Colony Ridge up to 11:30 PM Sunday night. This underscores the need to develop alternate evacuation routes for the fast growing subdivision.
Meanwhile, the flood threat is receding at Peach Creek and FM2090.
Caney Creek at FM2090 is getting back within its banks.
And the West Fork, however, is still rising. By 9 a.m. (six hours after the hydrograph below) it was out of its banks at US59.
Flood Warning Remains in Effect for West Fork Until Further Notice
Minor flooding is occurring and minor flooding is forecast.
Forecast…The river is expected to rise to a crest of 49.7 feet late this afternoon. It will then fall below flood stage late Wednesday morning.
Impact…At 49.3 feet, Minor lowland flooding begins in the vicinity of the gage. North side turnaround at US 59 begins to flood. Low points on Thelma Road, Aqua Vista Drive, and Riverview Drive begin to flood.
Flood History…This crest compares to a previous crest of 49.7 feet on 11/13/2008.
Here are photos taken along the West Fork this morning.
A young couple surveys rising floodwaters at the turnaround under the US59 bridge. The river bank is about a hundred yards in front of them at the sign in the background.This is the northwestern extent of Lake Houston.
A log jam forms from flood debris under the pedestrian bridge over the West Fork.
Floodwater had crept past the edge of Harris County’s Edgewater Park.
However traffic was still flowing on US59 in both directions.
About a third of the abandoned Noxxe Oil Field by the Forest Cove Little League fields was under water.
The soccer fields at River Grove were partially submerged. Yesterday they were mostly dry.
The boardwalk at River Grove was underwater except for the entrance.
There was no immediate threat to Kings Harbor though the dock was only inches above water.
As floodwaters work their way downstream, Lake Houston continues to rise. As of 5:30PM on 5/3, the lake is now up more than 1.6 feet and many docks are starting to go under.
No widespread flooding is expected in the Lake Houston Area. But people who live in low-lying areas or near the lake should take precautions.

The sign outside the abandoned Texas Concrete Sand and Gravel Mine in Plum Grove tells readers that an RV resort is coming soon. They might want to rethink that concept. Yesterday, rampaging floodwaters destroyed most of the mine except for a small area near the entry on FM1010.
Classic Example of Pit Capture
The East Fork rerouted itself right through the heart of the mine, sweeping away almost everything in its path. The river swelled to more than half a mile wide and ruptured dikes in at least four places when the river rose 10 feet in 24-hours.
The East Fork at this location rose 15 feet in three days, 10 of those in one day.
Normal course of river is red line on west side of mine. During flood, the river broke through the dike on the north side. Then floodwater filled the mine like a water balloon which burst in multiple places on the south side. Water now follows the yellow line.
This is a classic example of what geologists call pit or river capture. The East Fork entered the northern side of the mine and exited at multiple points on the south. Current coming out of the mine exceeded that in the river itself, carrying mud and muck downstream.
Flooding Based on Less than 10-Year Rain
The gage at this location indicated Plum Grove received only 3.36 inches of rain over a three-day period. However, up to 8 inches fell upstream from here, primarily during a two-day period. Jeff Lindner, Harris County’s meteorologist characterized the rains that produced the flood as, “Generally less than a 10-year event for the 48-hour time period.”
Pictures Taken on 5/3/2021
I took all of the shots below on 5/3/2021, three days after the major portion of the rain fell on April 30.
Looking north at the northernmost portion of the mine. The river appears to have entered the mine in this area.Note the dike in the far distance that’s not visible in the tree-line on the left.
Wider shot, still looking north toward entry point shows white water ripping through mine.
Looking south, you can see that the water in the mine is now higher and faster than the water in the river to the right.
Still looking south toward FM2090, now the only way in and out of Plum Grove. FM1485 is closed due to high water and FM1010 was washed out during Harvey by runoff from Colony Ridge to the southeast.
Looking north across FM2090. Where the water exits the mine, you can see that the force of the main flow is now misaligned with the bridge opening.
The width of the mine is now the width of the river…plus the river.Only the entry of the mine at the upper right remains above water at this time.
Looking east from over FM2090.
Danger of 2090 Washout in Next Big Flood?
Unless someone reroutes the river back to its original course and fixes the dikes, the current through the mine will continue to erode the banks of the roadway at the top of the image above.
These images dramatize the need for real sand-mining reform in Texas. There’s some evidence that Imelda did the same thing to this mine two years ago. But the TCEQ forced the company to repair the dikes. Now that the miners are gone, who will do that?
Plum Grove was lucky that upstream rains only amounted to a ten-year event. A larger storm could have cut the City and Colony Ridge off from the only viable evacuation route. More than 20,000 people would have been affected.
