Protesters Disrupt Crenshaw Town Hall in Kingwood on Harvey’s 8th Anniversary

8/30/25 – On the eighth anniversary of Hurricane Harvey, more than 400 residents crowded into the Kingwood Community Center to hear Congressman Dan Crenshaw talk. Unfortunately, a group of unruly agitators wouldn’t let the Congressman speak about flood mitigation to an audience whose lives had been upended by flooding.

They kept shouting questions about random, unrelated topics, such as lactation consulting. And before Crenshaw could answer one question, attackers would cut him off with another. Sometimes the attackers even stepped on each other.

Check out this representative 50-second clip of the hour-long audio recording I made…from the FRONT row. Transcription was hopeless.

It appeared as though the provocateurs were trying to get the police to eject them. That would have given them ammunition to slime Crenshaw further on social media.

The experience was an hour-long dystopian view of mob rule. Disruption, disturbance and disparagement replaced civilized discourse and debate. The volume of protesters’ voices drowned out Crenshaw’s attempts to illuminate issues.

That’s a real shame because he has a master’s degree in public administration from Harvard. Crenshaw is smart. Plus…

He has a deep understanding of issues and a gift for explaining them in ways that help people find common ground.

Shouts Overpower Microphone

Even though Crenshaw had a microphone, I had trouble hearing him. So, for those who attended hoping to hear what Crenshaw has done for flood mitigation in the area, here is partial text of his remarks obtained later from his staff.

Crenshaw’s Remarks on Flood Mitigation

“Through my work in Washington, I’ve been able to pull down federal dollars to help our local communities here in Lake Houston.”

“As you probably know, earlier this year we finally wrapped up a project that I had advocated for since I took office. The complete restoration of Lake Houston to pre-Harvey conditions. To date, over $150 million of federal funds have been used to dredge Lake Houston. The last $30 plus million project was completed near the convergence of the East Fork, West Fork and the lake.”

“I look forward to seeing the City maintain the lake with the newly approved Lake Houston Dredging District. This project was a long-fought effort by Charles Cunningham, Fred Flickinger and Twila Carter. It was unfortunate that my opponent, Steve Toth, voted against helping this community. 

“While the Lake Houston Dam is long overdue, I feel confident that we are on a good path and I am committed to expediting any federal permits required to get this project completed. For updates on the project, you should subscribe to Fred Flickinger’s newsletter.”

“Some other projects in the area that I secured Community Project Funding for are as follows:”

FY26 Projects -Submitted but Not Yet Approved

Woodridge Stormwater Detention Basin – $ 1M (We asked for $3 million.)

Purpose: The project aims to decrease flooding elevation within the San Jacinto watershed. It supplements funding obtained in previous years. [See below.]

Designed as a wet-bottom basin with a permanent pool of water and constructed with native wetland vegetation and features, this stormwater detention basin will function to treat and clean stormwater. The permanent pool of water will settle out solids, while the native vegetation will provide habitat for aquatic species that filter and clean stormwater.

FY24 Community Projects Signed into Law

Ford Road Improvement Project – $7 million

Purpose: This request will support Ford Road improvements from US 59 in Montgomery County to the Harris County line. The current road is undersized and serves as one of only three evacuation routes for the Kingwood area. Commissioner Gray is currently constructing this project. 

Kingwood Diversion Channel – Walnut Lane Bridge Project- $4 million

Purpose: The project includes the widening and reconstruction of Walnut Lane Bridge in Kingwood. This bridge, in its current configuration, will restrict flood flows unless widened to accommodate the future expansion of the Kingwood Diversion Channel currently being designed by the Harris County Flood Control District.

Taylor Gully Channel Conveyance Improvements Project-$1.75 million

Purpose: This project is designed to reduce flood risk in the Kingwood area. This project will create a detention basin and improve stormwater conveyance to minimize flood risks. Engineering studies show that completion of this project will result in substantial reductions in flooding along Taylor Gully.  The studies show that this project will remove the 100-year floodplain from over 115 acres of flood area and from 276 structures. 

FY23 Community Projects Signed into Law

Lake Houston Dam Spillway Project – $8 million

Purpose: This recently completed project reinforced the existing dam structure. The aging structure needed reinforcement and a project to replace this structure is underway. The dam gates will not be using this structure.

Woodridge Stormwater Detention Basin Project – $5 million

Purpose: The project involves creating a detention basin to alleviate flood risks in the Kingwood area. This project is critical for flood mitigation efforts in the district. 

Harris County Municipal Utility District (HCMUD) 468 Stormwater Detention Basin Project-$2 million

Purpose: This project is for the excavation of a stormwater detention basin located in the Cypress Creek watershed.  The Cypress Creek watershed is highly developed and has a lack of regional stormwater detention basins for flood mitigation.  This project is critical for flood mitigation efforts in the district and provides upstream detention to Kingwood

FY22 Community Projects Signed Into Law

Kingwood Diversion Channel – $1.6 million

Purpose: The Kingwood Diversion Channel improvements are proposed to divert stormwater runoff from the Bens Branch channel to lower the risk of structural flooding along the portion of Bens Branch within the Kingwood area.  This project will also provide capacity to allow for future local City of Houston neighborhood drainage improvements to outfall into the Kingwood Diversion Channel.

Taylor Gully Channel Conveyance Improvements – $1.6 million

This project will mitigate flooding on the north side of Kingwood. 

TC Jester Stormwater Detention Basin Project – $9.96 million

Purpose: This request is for TC Jester Detention Basin, which is a stormwater detention mitigation project within the Cypress Creek Watershed that is intended to address current flood damage reduction needs within the Cypress Creek Watershed.  This project will provide upstream detention to Kingwood. 

Westador Stormwater Detention Basin Project – $8.85 million

Purpose: This project will also provide upstream detention to Kingwood. 

Each of these wins – border security funding, energy permitting, flood infrastructure – came from listening to our community and then acting decisively.  

Crenshaw Deserves Even More Credit

Crenshaw didn’t say it, but the money he helped obtain for the Woodridge and Taylor Gully Projects also helped those projects qualify for $33 million dollars in CDBG-MIT grants. Harris County Flood Control District obtained those through the Texas General Land Office and the U.S. Department of Housing and Urban Development.

In contrast, Crenshaw’s primary opponent, State Representative Steve Toth, voted against the bill to create a Lake Houston Dredging District, even though it would not have raised taxes.

Dawn of a Disaster: Harvey Remembered

8/29/25 – Eight years ago today, the Lake Houston Area woke up to the dawn of a disaster. During the previous day and night, the San Jacinto River rose 22 feet above flood stage at US59.

It swept several townhomes in Forest Cove off their foundations. And destroyed all the rest for blocks around.

Rising floodwaters eventually claimed the lives of 15 people in the Kingwood area – 12 of them in a senior center more than a mile from the river.

Harvey was not a single day event. It lasted the better part of a week. Different areas fell to its driving rains and howling winds at different times.

Rainfall during Harvey recorded at the US59 Bridge over the San Jacinto West Fork. From Harris County Flood Control District’s Flood Warning System.

The Lake Houston Area bore the brunt of not only the storm, but water funneled downstream from an area 50% larger than Harris County itself.

That included a massive 79,000 cubic feet per second from Lake Conroe, the largest release ever by the SJRA.

Before It Was All Over…

16,000 homes and 3,300 businesses in the Lake Houston Area flooded.

The flood also destroyed thousands of cars. The owners parked many of them on higher ground that they thought was safe.

Troubles Just Beginning

But the hardest part was still to come: understanding why all this destruction happened and determining what could be done to prevent it from happening again. And finally, organizing politically to build the solutions.

We would soon discover that as much as we were united by disaster, we were also divided by recovery. That would become the dawn of a another disaster. But more on that in a future post.

SCIPP Research Sheds New Light on Key Elements of Tropical Systems

8/28/25 – NOAA’s Southern Climate Impacts Planning Program (SCIPP) just published its annual report. It includes new research findings on three key elements of tropical systems: a lengthening tropical season, stalling storms, and tropical cyclone size at landfall.

SCIPP publishes fascinating reports tailored to the south central region of the U.S. including Texas, Oklahoma and Louisiana.

The government/university partnership conducts research to understand climate hazard trends and patterns that are useful to decision makers. The information below is summarized from their annual report.

Tropical Season Lengthens 16 days

SCIPP analysis of Atlantic hurricane season length from 1970 to 2022 found that storms are forming increasingly earlier AND later in the season. In 1970, the first named storm formed around July 27th. However, by 2022, the date shifted to around May 31st. That represents an increase of season length of 11 days per decade … just on the front end.

On the back end, in 1970, the last named storm dissipated around October 24th. However, in 2022, the last storm dissipated around November 18th. This represents a roughly 5-day per decade shift, say the researchers.

“While improvements in observational practices raised some concerns about data quality,” they say, “our results suggest that the primary driver of season expansion is the earlier onset and prolonged persistence of favorable conditions for tropical cyclones, such as warm sea surface temperatures, elevated humidity, and reduced wind shear.”

The researchers recommend that the National Hurricane Center consider moving the start of hurricane season to May 15th to heighten awareness of these early season storms. They have presented their work widely within the scientific community. For more information, see Dr. Vincent Brown’s virtual presentation to the Inland Marine Underwriters Association.

Stalling Storms Increasing 1.5% Per Year

SCIPP researchers also found seasonality in stalling storms. Stalling is most common in October (17.3% of storms) and least common in August (8.2%).

Their analysis showed a significant increase in annual stalling frequency during the satellite era (1966–2020) at 1.5% per year.

They also found an increase in the proportion of stalling storms relative to all storms.

SCIPP 2024-2025 Annual Report

Stalling storms were also significantly more likely to reach major-hurricane intensity.

These findings have been presented to stakeholders, academic audiences, and emergency managers to help them better prepare for future stalling events in vulnerable regions.

“Size at Landfall” Increasing Later in Season

The third featured project was a database of tropical cyclone size at landfall.

Size at landfall is critical in determining the extent and severity of storm impacts.

SCIPP 2024-2025 Annual Report

Accurate size data allows emergency managers, planners, and policymakers to better estimate potential exposure, improve evacuation planning, allocate resources, and design infrastructure that accounts for the full spatial footprint of storms. Their database supports:

  • Enhanced risk assessments
  • Insurance modeling
  • Building codes
  • Long-term coastal planning.

The analysis found no statistically significant long-term change in size at landfall, However, it did find that:

  • Parts of the season—particularly September through November—exhibited larger landfall sizes compared to other months.
  • Average landfall size was comparable between the Gulf of Mexico and the East Coast.
  • Size did not differ significantly across Category 1–4 storms.

Implications of the Three Studies


SCIPP says that collectively, these three studies highlight the “critical need to better understand tropical cyclone characteristics that directly affect coastal populations.”

The researchers hope to translate their scientific findings into actionable guidance for emergency management, infrastructure planning, and long-term community resilience.

The annual report also contains fascinating findings by leading academic institutions in the region on:

  • Hazard mitigation in areas without hazard mitigation planning capabilities
  • Heat stress and football-game kickoff times
  • Impacts of fiscal decentralization on Disaster Risk Reduction
  • Climate migration
  • Case studies
  • Workshop and intern opportunities
  • More

SCIPP’s theme is “Planning for Long-Term Change in a Short-Term World.” To learn more about their excellent work and conferences, or to sign up for their newsletters, visit SouthernClimate.org.

Hurricane Stats for Gulf Coast and Texas Going Back to 1850

8/27/2025 – This week marks the 8th anniversary of Hurricane Harvey and the 20th anniversary of Hurricane Katrina – two of the most destructive storms in recent American history. So I wanted to see what the hurricane stats tell us about this part of the hurricane season as far back as we can reliably see.

The National Hurricane Center has an excellent climatology page for the broader Atlantic basin. But I could not find any lists on their site for the Gulf and Texas. So I asked ChatGPT for some research help narrowing the geographic scope. Here’s what it found in the data.

Notable Late August Major Hurricanes to Strike Gulf Coast

Several major hurricanes have struck the U.S. Gulf Coast in late August (roughly August 20–31) over the years. Here are the most notable ones:

1. Hurricane Katrina (2005)
  • Dates: August 23 – 30, 2005
  • Landfall: August 29 in southeast Louisiana and Mississippi
  • Impact: One of the costliest and deadliest U.S. hurricanes; catastrophic flooding in New Orleans after levee failures.
2. Hurricane Laura (2020)
  • Dates: August 20 – 29, 2020
  • Landfall: August 27 near Cameron, Louisiana (Category 4, 150 mph winds)
  • Impact: Devastated southwest Louisiana, massive storm surge and wind destruction.
3. Hurricane Harvey (2017)
  • Dates: August 17 – September 2, 2017
  • Landfall: August 25 near Rockport, Texas (Category 4)
  • Impact: Record-breaking rainfall in Houston region (up to 60″), catastrophic flooding across southeast Texas.
4. Hurricane Isaac (2012)
  • Dates: August 21 – September 1, 2012
  • Landfall: August 28 in southeast Louisiana (Category 1)
  • Impact: Widespread flooding, long-duration storm surge, power outages.
5. Hurricane Gustav (2008)
  • Dates: August 25 – September 4, 2008
  • Landfall: September 1 in Louisiana (Category 2), but struck the Gulf Coast region late August while strengthening.
6. Hurricane Andrew (1992)
  • Dates: August 16 – 28, 1992
  • Landfall: August 24 in South Florida, then August 26 in Louisiana (Category 3)
  • Impact: One of the most destructive U.S. hurricanes prior to Katrina.
Other Notable Late-August Gulf Hurricanes
  • 1886 Indianola — Aug 20 • TX • Cat 4
  • 1945 Texas Hurricane — Aug 27 • TX • Cat 3.
  • Hurricane Camille (1969): Landfall August 17 (slightly before “late August,” but historic impact on Mississippi).
  • Hurricane Allen (1980): Active early to mid-August, not late August.
  • 1999 Bret — Aug 22 • TX • Cat 3.
  • Hurricane Ida (2021): Formed August 26, made landfall August 29 in Louisiana as Category 4.

✅ Pattern: Late August is part of the peak hurricane season in the Gulf; multiple historic storms—including Katrina, Harvey, Laura, and Ida—all struck between August 25–29.

Two Thirds of All Gulf Coast Hurricanes Strike in August and September

Next, I asked ChatGPT to graph the distribution of all hurricanes (not just majors) to strike the Gulf Coast by month since 1851. NOAA last updated this information in 2020. So, these numbers do not include the last 5 years.

The total was 212; 141 in August and September. That works out to 66.5% of the total.

Counts by month (1851–2020) of all Gulf Coast Hurricanes:

  • June: 9
  • July: 17
  • August: 58
  • September: 83
  • October: 39
  • November: 6

👉 The peak is September, followed by August, then a secondary bump in October. Early (June–July) and late (November) landfalls are much rarer.

Texas Shows Even More Pronounced Concentration in August/September

By contrast, seventy-one percent of all Texas Hurricanes happen in August and September, a slightly higher concentration. We also get proportionately fewer in October compared to the entire Gulf.

Texas hurricane landfalls by month from 1851-2020 include:

  • June: 5
  • July: 7
  • August: 25
  • September: 29
  • October: 9
  • November: 1

Pattern of Active Decades

The distribution suggests clusters of active decades rather than a steady increase or decrease.

List of Texas Hurricane Landfalls

Here’s a historical list of Texas hurricane landfalls (1851–2020), drawn from NOAA’s official Hurricane Research Division dataset. I’ve grouped them by month and included year, name (if available), and Saffir–Simpson category.

June (5 total)
  • 1871 – Indianola hurricane (Cat 3)
  • 1886 – Indianola hurricane (Cat 4, destroyed the city)
  • 1934 – June hurricane (Cat 2)
  • 1957 – Audrey (Cat 3, TX/LA border, strongest in LA but impacted TX)
  • 1960 – Unnamed June storm (Cat 1)

Beryl last year would be a notable addition to this list if we expanded the range of years.

July (7 total)

  • 2008 – Dolly (Cat 1, near Brownsville)
  • 2008 – Ike (Cat 2, Galveston/Houston, catastrophic surge)
  • 2017 – Harvey (Cat 4, Rockport/Port Aransas, record flooding in Houston area)
    (and numerous weaker Cat 1–2 storms in between)
September (29 total)
  • 1900 – Galveston hurricane (Cat 4, deadliest natural disaster in U.S. history)
  • 1919 – Florida Keys / Corpus Christi hurricane (Cat 4, catastrophic in Corpus Christi)
  • 1933 – September hurricane (Cat 3, Brownsville)
  • 1967 – Beulah (still active early September after Aug landfall)
  • 2002 – Lili (weaker in TX, major in LA)
  • 2020 – Hanna (Cat 1, South Padre region)
    (plus ~20 others Cat 1–3 from NOAA HRD record, mostly South Texas landfalls)
October (9 total)
  • 1837 – Racer’s Storm (Cat 3, Galveston/Houston area, extensive damage)
  • 1886 – October hurricane (Cat 2, south TX)
  • 1912 – October hurricane (Cat 2, Gulf coast TX/LA border)
  • 1949 – October hurricane (Cat 2, Freeport area)
  • 1989 – Jerry (Cat 1, near Galveston)
November (1 total)
  • 1980 – Hurricane Jeanne (Cat 1, weakened quickly at landfall in south Texas)
✅ Key Pattern:
  • Peak months for Texas hurricane landfalls are August & September
  • The most destructive TX hurricanes historically include:
    • 1900 Galveston (Cat 4)
    • 1915 Galveston (Cat 4)
    • 1919 Corpus Christi (Cat 4)
    • 1961 Carla (Cat 4)
    • 1983 Alicia (Cat 3)
    • 2008 Ike (Cat 2, massive surge)
    • 2017 Harvey (Cat 4, catastrophic flooding)
1900 Galveston Hurricane Still Deadliest Ever

The 1900 Galveston Hurricane (September 8, 1900) remains the deadliest natural disaster in U.S. history. Estimated deaths range from 6,000 to 12,000. But the most widely cited figure is 8,000. Roughly one-third of Galveston’s population perished, thousands of homes were destroyed, and the disaster reshaped how the U.S. approached hurricane forecasting and preparedness.

By contrast, Hurricane Harvey in 2017 killed 68 people statewide and 36 in Harris County. You can attribute the improvement (reduction) to better forecasting and infrastructure.

MoCo Adopts New Drainage Criteria Manual 8 Years After Harvey

Montgomery County has finally updated its drainage criteria manual…eight years after Hurricane Harvey caused widespread flooding that exposed shortcomings in its previous manual which dated to the 1980s.

Unanimously Approved

MoCo Commissioners approved the new manual unanimously this morning. The draft of the new manual was first proposed in early 2024. That followed a minor update in 2019 from the county’s old 1988 drainage criteria manual in effect at the time of Harvey.

The new manual does not adopt all of the minimum drainage recommendations proposed by Harris County for areas draining into Harris, though it is a vast improvement over the previous iteration.

Minimum Drainage Requirements Proposed by Harris County

The minimum drainage requirements proposed by Harris County included five key measures:

1. Using Atlas 14 rainfall rates for sizing storm water conveyance and detention systems.
2. Requiring a minimum detention rate of 0.55 acre-feet per acre of detention for any new development on tracts one acre or larger. A single-family residential structure and accessory building proposed on an existing lot is exempt from providing detention.
3. Prohibiting the use of hydrograph timing as a substitute for detention on any project, unless it directly outfalls into Galveston Bay.
4. Requiring “no net fill” in the current mapped 500-year floodplain, except in areas identified as coastal zones only.
5. Requiring the minimum Finished Flood Elevation of new habitable structures be established at or waterproofed to the 500-year flood elevation as shown on the effective Flood Insurance Study.

Major Changes in New MoCo Drainage Criteria Manual

MoCo’s new drainage criteria manual includes some, but not all, of those recommendations.

Comparison of Recommendations
MeasureHarris Montgomery 
Use of Atlas 14 Rainfall StandardsYesYes
Minimum Detention Rate.55 acre feet/acre.55 acre feet/acre for areas greater than 20 acres (see page 57)
Prohibit Hydrographic TimingYesYes, but with limitations (see page 68)
No Net Fill in 500-Yr FloodplainProhibitedStill allowed
Finished Floor ElevationAt 500-yr flood elevationRequires drainage be maintained one foot below lowest finished floor elevation for 100-year event (See page 54)

It’s not perfect. But it’s a vast improvement. Assuming the county enforces them.

For ease of future reference, you can find Montgomery County’s new, updated Drainage Criteria Manual on the Reports page under the Regulations tab.

Suggestions by MoCo Resident

Montgomery County resident Chad Price addressed Commissioners Court before the vote. He applauded most of the updates in the manual. However, he also urged commissioners to adopt ALL of Harris County’s minimum requirements.

Chad Price addressing MoCo Commissioners Court. The drainage discussion starts at 1:14 into the video.

Price emphasized the uncertainty surrounding rainfall rates, the increasing frequency of storms that exceed predicted maximums, and flood maps that have yet to be updated to reflect Atlas-14.

He made two excellent points:

  • We must not design drainage systems based on outdated data.
  • Better flood regulations are not about stopping growth—they’re about making sure growth is sustainable and safe. 

In that regard, Price urged commissioners to update building codes, require smarter drainage planning, preserve natural floodplains, and use science-based floodplain mapping. He said, “These steps will reduce long-term costs to taxpayers, protect property values, and most importantly, safeguard our communities.”

Next Up

Montgomery County’s Floodplain Manager currently shows floodplain regulations adopted in 2014. That’s before the Tax Day, Memorial Day, Harvey, Imelda and May Day 2024 floods. Given the thousands of homes in MoCo that flood repeatedly, there may be some opportunities for improvement in those floodplain regs.

Northpark Shaping Up

8/25/25 – For the first time since authorities broke ground for the Northpark expansion project in April 2023, it’s possible to clearly see the outlines of the finished project on the ground. The first all-weather evacuation route from Kingwood is shaping up nicely.

For the most part, contractors have straightened out the zigs and zags. They have finished large sections of the westbound lanes. Drainage for the eastbound lanes is progressing nicely. And soon they will start pouring concrete for large sections of the remaining eastbound lanes.

Pictures Taken on 8/25/25

The drone pictures below show the progress…starting from Russell Palmer Road and heading east.

Notice how virtually all of the old Eastbound concrete has been removed as far as the eye can see.
Looking W from near Warren’s Southern Gardens

Contractors are installing drainage under the westbound lanes. However, the drainage work is moving from west to east.

Looking West from near the Kolache Factory and the entrance to Kings Mill.
Today, they were working near the Kolache Factory.
Father west, sidewalks have already been installed on the north side of the street.

The photo above shows approximately where the bridge over the railroad tracks and Loop 494 will start. Notice how two lanes veer right to make room for the bridge.

Connecting the drainage from the east and west sides of the railroad tracks will require the twin five foot steel pipes stockpiled in the foreground.

However, work on boring under the tracks has stalled for now. But the Lake Houston Redevelopment Authority believes that the utility conflicts which have delayed that operation will soon be resolved. Then boring under the tracks can resume.

Looking N along Loop 494. Note how one of the bore pits is blocking completion of the northbound expansion lanes.
Looking S along 494 from over Northpark.
Between Loop 494 and 59, crews are still connecting drainage under the roadway.
Right now, they’re finishing the connection in front of Whataburger.
Almost at US59, crews are making room for the surface lanes that will flank the bridge.

Looking in the opposite direction…

Those surface lanes will also connect to the surface lanes east of Loop 494 (right of the pavement.
The new development on the SE corner of Northpark and Loop 494 will be called the Enclave.

The developer plans to build a 100 homes in the Enclave.

Massive Sand-Mine Breach Empties Hundreds of Acre-Feet into West Fork

8/24/25 – The abandoned Hanson Aggregate sand-mine on the San Jacinto West Fork had a massive breach of its northern dike this evening – unrelated to weather. According to the Montgomery County Appraisal District, Heidelberg Materials Southwest AGG LLC now owns the property where the breach occurred.

Location of breach circled in red.

Breach Discovered Shortly after 6 PM on 8/24/25

A thousand acre-feet of water or possibly more rushed out of the 140-acre pond, obliterating everything in its path, and depositing enough sand and silt in the San Jacinto West Fork to back water up in the river.

I received a call from a neighbor who alerted me to the breach at 6:38 PM. And by the time I arrived shortly after 7 PM, the water level in the pond had dropped an estimated 8-10 feet he said.

Water was still rushing out of the pond fast enough to cause large chunks of the shore to break away, endangering onlookers who had to back away.

The water eroded a channel approximately 800 feet long, 50 to 200 feet wide and perhaps 15-20 feet deep – all in a matter of minutes.

The cause of the breach is unknown. However, aerial photos showed a small excavator and piles of drain pipe near the breach.

Photos, Video Taken Between 7 and 8 PM on 8/24/25

Below are photos and video of the devastation.

There Must Be A Better Way!

Ironically, this mine had one of the largest setbacks on the West Fork. (See satellite image above.) The setback varied from approximately 400 feet to more than 1,000. However, there was a small drainage channel running along the northern edge of the mine that had a narrower setback And that’s where the breach occurred.

This disaster underscores the need to find a permanent, safe solution for abandoned sand mines along area rivers and streams.

I previously proposed aggregating them over time into a West Fork Greenway which could become a state park. I tentatively named the concept the Montgomery County Lake District.

Instead of letting such mines remain a dangerous blight, turn them into a recreational amenity that could add value to area homeowners and developers.

ChaptGPT Develops Harris County Flood Resilience Plan for Free in 2 Minutes 52 Seconds

8/23/25 – ChatGPT produced a detailed Flood Resilience Plan for Harris County for free in less than three minutes. Meanwhile, after almost a year, the engineering firm hired by Harris County for $3 million is still trying to define a vision for the plan.

Flood Resilience Plan on Agenda for Tuesday’s Commissioners Court Meeting

Item #407 on the agenda for Harris County Commissioners Court on 8/26/2025 is an update by Harris County Flood Control District (HCFCD) on the status of its effort to develop a county-wide Flood Resilience Plan. On October 8, 2024, the County approved hiring AECOM, a private engineering company, for $2,998,388, to develop the plan. See Item 336 on that agenda.

Almost a year later, the participants are still trying to establish a vision. They hope to finalize their goals by Spring 2026.

From Flood Resilience Plan Plan status update to Commissioners Court for discussion on 8/26/25

It seems like it’s taking the company a long time to get out of the starting blocks. So, I decided to see how long it would take ChatGPT to develop a resilience plan for the county. It took two minutes and 52 seconds and cost nothing.

Now, I am sure that experts at AECOM and Flood Control would still have to review and validate the recommendations. But this seems like a great start to me. It’s clear, concise, readable, and actionable. And it potentially saved about half of a $3 million contract. Below, see the simple question I asked and the response I got.

“Chat, can you develop a flood resilience plan for Harris County, Texas?”

Chat: Absolutely, here’s a practical, Harris-County–specific flood resilience plan you can put to work now. I’ve organized it as (1) guiding principles, (2) 12 action pillars with concrete steps, (3) a 100-day / 1–2 yr / 5–10 yr timeline, and (4) funding + governance + metrics. Sources are cited throughout.

Guiding Principles (What “Good” Looks Like)

  • Design to today’s risk (Atlas 14) and rising extremes. NOAA’s 2018 Atlas 14 raised the region’s 1%-annual-chance (24-hr) rainfall from ~13″ to ~17–18″; plan to that (and stress-test above it).
  • Map the real pathways of flooding, not just rivers. Use MAAPnext’s overland “community flooding” products while FEMA reviews new FIRMs.
  • No Adverse Impact (NAI). New development should not increase risk elsewhere—codify and enforce NAI countywide.
  • One watershed system. Coordinate cities, county, TxDOT, USACE, upstream counties, and sand-mine operators so conveyance, detention, and maintenance work as a system.

12 Action Pillars

1) Finish modern risk mapping & put it to work
  • Operationalize MAAPnext (overland flooding, velocities, mobility impacts) for capital planning and development review now, while FEMA finalizes the maps. Continue public-facing tools (M3, Flood Education Mapping Tool) with clear “effective vs. preliminary” labeling.
  • Close the FEMA gap. Press FEMA and the State to accelerate preliminary→effective FIRMs (current public reporting notes continued delays into 2026). Use county policy to consider MAAPnext where it’s the best availabledata. (Houston Chronicle)

Quick metric: % of permits reviewed against MAAPnext + Atlas 14 criteria (target: 100%).

2) Lock in stronger, uniform standards (countywide + cities)
  • Keep Atlas-14 standards in the HCFCD PCPM (2019) and Harris County infrastructure regs, and close any variance loopholes. Align municipalities to the same floor.
  • Freeboard: Maintain City of Houston’s 2 ft above 500-yr (Ch.19) standard citywide; aim for 2 ft freeboard in AO, A, AE, and shaded X in unincorporated areas as a county minimum.
  • Detention & outflow controls: Enforce post-Atlas-14 detention rates and multi-frequency release; require on-site peak and volume controls sized to tailwater realities.
  • Adopt NAI ordinance language (ASFPM model) to make “no measurable rise/no new harms” enforceable.

Quick metric: % plats meeting NAI and Atlas-14 detention without variances.

3) Deliver a prioritized capital program by watershed

Focus on the 23 watersheds with a scored, public list: benefits per $1, structures removed from risk, equity (CFRTF lens), and O&M burden.

Countywide priorities:

  • Regional detention & conveyance upgrades tied to Atlas 14, coordinated with city storm sewers and TxDOT outfalls.
  • Sediment management at scale. Expand the FEMA-funded channel desilt program that secured nearly $250M in 2021; make “design for maintainability” standard in new projects.
  • Stormwater tunnels as a targeted tool (e.g., Buffalo/Greens/Halls corridors) advancing feasibility toward a pilot where they outperform surface options—stay evidence-led and transparent on cost/benefit.
  • SAFER planning build-out. Use the new SAFER study (covering ~half the county’s watersheds) to feed the project hopper and federal asks.
  • Lake Houston spillway gates & dredging. Support the City/Coastal Water Authority in completing gate design and long-term maintenance dredging strategy for the West Fork delta reach.

Watershed notes (examples):

  • Buffalo Bayou / Addicks & Barker: Coordinate with ongoing USACE Buffalo Bayou & Tributaries work; keep options open (selective widening, detention, or tunnels) per federal study direction.
  • Greens/Halls: Prioritize conveyance + storage + potential tunnel pilot (equity win with high benefit density).
  • San Jacinto (Spring, Cypress, mainstem): Accelerate regional detention partnerships upstream; integrate sediment traps and set-back rules near pits to reduce delta growth in Lake Houston. (See Pillar 6 & 7.)

Quick metric: public “Top 50” project list with BCR, equity score, O&M cost.

4) Buyouts & floodplain preservation at scale
  • Two tracks: (a) Voluntary buyouts (HCFCD) where projects are infeasible; (b) county Project Recovery mandatory area program where risk is intolerably high. Keep the “stay in-county” relocation incentives.
  • Greenways & storage: Convert acquired land to passive storage/greenways to reduce future risk and add value.

Quick metric: buyouts closed per quarter; open-space acres added.

5) Maintenance: make capacity durable
  • Fund a permanent desilt & repair program using FEMA/NRCS where eligible; publish a rolling 3-yr maintenance map.
  • Design for maintainability (access benches, hardened inlets, riparian stabilization) in every capital project.

Quick metric: miles of channel restored to design capacity per year.

6) Sand-mine & pit-capture risk reduction (San Jacinto focus)
  • Codify river set-backs, armored crossings, and flood emergency plans for in-floodplain pits; align local criteria with TCEQ quarry BMP rules (30 TAC 311 Subchapter J).
  • Create a pit-capture remediation fund seeded by performance bonds/fees; require post-mining reclamation to flood-safe end uses.

Quick metric: % pits with compliant flood plans; # of reclaimed pits.

7) Streets as secondary channels (urban flooding)
  • City/County program to upsize storm sewers and raise sag points where MAAPnext shows ponding; synchronize with roadway rehab.
  • Critical facility hardening & dry access (hospitals, shelters, EOCs) against MAAPnext mobility maps.

Quick metric: lane-miles where depth–velocity at 1% event drops below hazardous thresholds.

8) Early warning, gauges, & comms
  • Expand Harris County Flood Warning System (more gages in sheet-flow basins; redundant power/comms), integrate push alerts and low-water crossing sensors.
  • Neighborhood-level nowcasts and standardized evacuation/road closure criteria.

Quick metric: % population within 3 miles of a rain+stage gage.

9) Coastal surge interface (doing both: surge and rain)
  • Track Coastal Texas / “Ike Dike” components and ensure interior drainage (gate-closed conditions) is accounted for in our designs. Surge protection won’t fix rainfall flooding—plan for both.
10) Equity & community governance

Quick metric: % of projects with documented CFRTF input; equity score trend.

11) Funding stack & federal alignment
  • Annualized grant calendar & “shovel-ready” shelf: FEMA BRIC/FMA/HMGP; TWDB Flood Infrastructure Fund (FIF) 2024–25 cycle; CDBG-MIT; NRCS EWP; USACE/WRDA; Texas Water Fund.
  • Bond program transparency. Keep the 2018 Bond dashboards, “completed Bond IDs,” and press updates current to maintain match-making credibility with federal partners. (Harris County Flood Control District)

Quick metric: external $ leveraged per local $ (target: ≥2:1).

12) Data, transparency, and O&M lifecycle costs
  • Single public map integrating: project pipeline & status, MAAPnext layers, buyout tracts, maintenance backlog, mowing/repairs, and 12-month bid outlook.
  • O&M endowment concept: dedicate a slice of every capital dollar to long-term upkeep.

Timeline

First 100 days
  • Publish a Top-50 priority projects list (with BCR, equity, O&M).
  • Adopt NAI ordinance language and reaffirm Atlas-14 PCPM as the countywide minimum.
  • Stand up a MAAPnext-based development review policy for best available data.
  • Announce an expanded desilt/repair schedule (3-yr horizon) and launch low-water crossing sensor pilots.
  • File pre-applications for FEMA BRIC/FMA, TWDB FIF, NRCS EWP on the Top-50 set.
1–2 years
  • Let construction for the first 15–20 high-BCR projects across multiple watersheds.
  • Close 1,000+ buyouts in deepest risk pockets; green them into storage/greenways.
  • Complete SAFER recommendations → add to pipeline and federal asks.
  • Advance Lake Houston gate design and a long-term delta dredging framework.
5–10 years
  • Deliver full regional detention + conveyance corridors (multi-benefit parks where feasible).
  • If merited by feasibility, design/construct a tunnel pilot in the corridor with the strongest cost-effectiveness and equity benefits.
  • Integrate interior drainage with Coastal Texas components as they progress.

Funding (How to Pay for It)

  • Federal: FEMA BRIC/FMA/HMGP, USACE (WRDA), NRCS EWP, FHWA ER.
  • State: TWDB FIF (planning, design, construction), Texas Water Fund; coordinate with GLO on CDBG-MIT.
  • Local: HCFCD 2018 Bond balances; city drainage funds; utility/impact fees aligned to Atlas-14/NAI. Keep the Completed Bond ID reporting up to date to strengthen match prospects. (Harris County Flood Control District)

Governance & Roles

  • HCFCD: capital delivery, maintenance, MAAPnext/M3, bond & grant execution. (Harris County Flood Control District)
  • Harris County Engineering + cities: subdivision codes, storm sewers, streets-as-channels, floodplain regs.
  • CFRTF: equity scoring, community co-design, transparency. (Harris County Judge)
  • USACE/TxDOT/TWDB/FEMA/GLO: federal/state partners (funding and big-ticket works).

Toth Fights for Right to Build Kids’ Camps in Floodplains

8/21/25 – State Representative Steve Toth, who has announced his intention to run against U.S. Congressman Dan Crenshaw in the next election cycle, posted a video on Facebook today. In it, he says prohibiting the building of youth camps in floodplains is “ridiculous.” He also worries that it would “destroy camping in Texas.”

His comment about destroying camping is a slap in the face to the parents who lost children at Camp Mystic in the July disaster on the Guadalupe River. More than 135 people died in flash flooding, many of them young girls at Camp Mystic.

Toth Video

Below is the 48-second video that Toth posted.

Text of Toth Video

Because of background noise in the video, I’ve transcribed the text below.

Toth: “HB-1 sets up legislation to protect kids from the devastating floods that took so many lives at Camp Mystic. Only the amendment that the Democrats put on it basically restricts the building of any kind of sleeping quarters in floodways, not floodplains. The kids that were killed at Mystic were actually in a floodway.”

“This is going to basically close most of the youth camps in Texas. Twenty percent of Texas is in floodplains – not floodways – floodplains. And while, yes, we want to keep camps out of floodways … the idea of trying to say that you can’t build in a floodplain is ridiculous. This is going to destroy camping in the state of Texas.“

Specifics of Bill and Amendments

HB-1 is the Youth CAMPER Act. CAMPER stands for youth Camp Alert, Mitigation, Preparedness and Emergency Response. The bill requires youth camps to develop emergency plans; train employees how to implement them; make the plans available to campers and their parents; and share them with emergency response personnel in the vicinity.

Here’s the full text of the bill as introduced, which Toth co-authored with dozens of his colleagues. For more on HB-1, see the House analysis.

Representative Donna Howard, a Democrat from Austin (another co-author of the bill) offered the amendment that Toth complained about. It says that a state license may not be issued or renewed “for a youth camp that operates one or more cabins located within a floodplain.” Elsewhere in her amendment, Howard defines “floodplain” as the FEMA 100-year floodplain.

Howard’s amendment passed 73 to 59. Toth voted against it, even though he later voted for the bill itself as amended. HB-1 passed in the House by 135 to 1. The engrossed (as amended) version now goes to the Senate.

Problems with Toth Claims

Toth makes several misleading statements in his video.

Implying All Victims in Floodway

Toth implies all fatalities occurred in cabins located in the floodway of the Guadalupe. However, news reports indicate that many of the victims were in cabins outside the floodway although I can’t find an official count at this time.

Implying It’s Safe to Build in Floodplains

Mr. Toth implies that if all the campers had slept in the floodplain instead of the floodway, they would have been safe. That’s like a drug company downplaying a dangerous side effect.

Almost six million people live in Texas floodplains. And according to USGS, Texas consistently leads the nation in flood-related fatalities. In fact, we have more than twice the number of the next nearest state. 

Serious Omissions

In Mr. Toth’s black-and-white view of flood risk (Floodway is bad; floodplain is safe), he fails to disclose the considerable uncertainty, politicking, and protesting that accompanies flood maps, largely because of the way they affect developers and flood insurance. Toth should know that if he’s running for Congress.

FEMA’s maps are based on statistical probabilities and often revised after major storms to reflect new knowledge. In the case of Camp Mystic, FEMA last revised that area’s flood maps in 2011, years before Hurricane Harvey and Atlas 14. Both the floodway and floodplains will expand based on newly acquired data. So, cabins shown outside the floodway are, in all likelihood, deep into it. That’s another potentially fatal misleading statement by Toth.

Camp Mystic in FEMA’s National Flood Hazard Layer Viewer. Cross-hatch = floodway. Aqua = 100-year floodplain. Tan = 500-year floodplain. Note small green type showing date of map: 2011. Great enlargement shows many of the cabins appear to be built in the aqua and tan areas in the upper right next to the floodway.
“Saying You Can’t Build in a Floodplain is Ridiculous”

Mr. Toth seems to be trying to legitimize building in floodplains. It’s true that many people do. In fact, about 20% of the people in Texas (5.9 million) live in 100- and 500-year floodplains. Toth seems to dismiss the risks, costs, deaths, and disruptions to the economy, like many before him.

Because of thinking like that, more people live in Texas floodplains than the populations of 30 states. And that comes at a tremendous cost to taxpayers, not just those who pay with their lives.

As a society, we spend trillions of dollars on flood mitigation, flood repairs, and flood insurance. The Joint Economic Committee (JEC) estimates that the total annual economic cost of flooding—covering infrastructure damage; lost productivity; home and commercial damage; ecosystem losses; and more—ranges between $179.8 billion and $496.0 billion in 2023 dollars.

That’s a pretty hefty share of the annual federal budget. But I guess Mr. Toth isn’t thinking that far ahead. That’s not good for a man who wants to represent you in Congress.

Need for Performance Audits To Ensure Timely Flood-Plan Implementation

8/20/25 – Everyone understands the need for financial audits; they prevent fraud. But what about performance audits? They can prevent waste. Yet how many government agencies routinely audit the implementation of plans they adopt?

Vermont Failed to Implement Half of Priorities in Emergency Plan

In Vermont last year, the state audited its performance in achieving its five-year hazard-mitigation plan. According to the Associated Press story, the plan is developed by Vermont Emergency Management every five years to identify natural hazards facing the state and take steps to reduce risk, including flooding risk.

But an audit released last year after a major flood found that only a third of the 96 actions, and half of the priority actions in the 2018 plan had been completed. Had flood-mitigation measures been completed in a timely manner, the audit says, communities affected by the floods would have been better able to withstand them.

State lawmakers said they were gravely concerned over the lack of progress. “The findings in this report are shocking and deeply troubling,” one said.

The director of the State’s Emergency Management Department called the plan “aspirational.”

But the audit focused on missed opportunities that could have lessened the severity of the floods, such as improved building codes, that would have helped communities recover faster. That sounds pretty practical to me.

Improved Harris County Building Codes Reduced Flood Damage 20X

A study by a former Harris County Engineer John Blount found subdivisions built to new, higher building codes before Hurricane Harvey experienced 20 times less damage than those that weren’t. Building codes are updated internationally every year, but Texas last updated its building codes in 2021.

New Floodplain Maps Years Past Due

Everyone agrees on the need for updated flood maps based on Atlas 14. But Harris County’s are years behind schedule. And some counties still base their flood maps on data acquired in the 1980s. In the meantime, people keep building and buying in floodplains based on outdated information. And one in every five Texans lives in a floodplain. Are we creating the conditions for future disasters?

Plans Without Financial Pathways

Why do we continually build plans that are not actionable? That are so long, no one can read or remember them?

  • We spent seven years building a state flood plan. It has a $54.5 billion price tag. But since 2019, the state legislature has allocated only $1.4 billion to the state’s Flood Infrastructure Fund.
  • Houston’s Resilience Plan? Just five years after its introduction, it’s now a maze of dead links and appears to have virtually disappeared from the web.
  • Harris County’s Flood Bond? Eight years into a ten year plan that’s 40% complete, HCFCD’s executive director claims they are $1.3 billion short already, but has been trying for months to explain why.
  • Ike Dike? Hurricane Ike struck Houston in 2008. Congress approved the project in 2022. The Corps estimated the cost at $57 billion in 2023. TWDB is still studying ways to break it down into bite sized chunks.
  • Flood Tunnels? In 2022, HCFCD produced a 1,860 page study projecting the cost for eight to be $30 billion. We’re still studying pilot projects on that one.
  • In the summer of 2020, the San Jacinto River Authority, City of Houston, Montgomery County and Harris County Flood Control District released a 3,600 page study about how to reduce flooding in the San Jacinto River Basin. At the time, it had a $3.3 billion price tag. So far, the partners have not constructed one recommendation.

We Need More of a Business Mentality in Government

In my opinion, we need less nonsense and more commonsense. Who would accept a position with a job description that’s 3,600 pages long? Or a monumental list of deliverables without any budget?

It’s good to dream. But we need government leaders who know how to produce results on a budget. Just like business leaders do.

I’d rather see one project in construction than a hundred sitting on a credenza.

Bob Rehak

Perhaps performance auditors can help us turn that around.
