I first interviewed Tammy Gunnels and her husband Ronnie almost three years ago. They had flooded ten times at that point even though they weren’t in a flood zone. The Gunnels are devout people and prayed for a buyout. Friday, their prayers were answered. Here is the story of how their faith and persistence paid off in the long run. This interview also included Morgan Lumbley, the Disaster Recovery Manager for Montgomery County who guided the Gunnels through the application process.Ironically, the skies unleashed torrential rains just before the closing. But this time, everyone was smiling instead of worrying.

Early Frustration
Bob: You flooded 13 times in 11 years. Tell me how you finally got the buyout offer.
Tammy: After Harvey, one of my cleaning clients who’s an attorney vowed to find a way to get us a buyout. She put me in touch with the Office of Emergency Management for Montgomery County. Initially, they told me there were no open programs available.
Tammy: That was in 2017. Then in May of 2019, we flooded twice – on May 3rd and again on May 7th. Once more, I contacted their office and went to commissioners meetings, begging for a buyout. But nothing happened. After we flooded a third time that year during Imelda, I called their office just to scream and holler and cry into the phone. But this time, Morgan answered. I told her our story and by the end of the conversation, she was crying and promising that she was going to do everything she could.
Patience Finally Pays Off
Bob: And she wrote a beautiful note.
Tammy: She put it on her computer where it stayed until today. It says, “No one before Miss Tammy. Number one priority.” Later, she called back and said, “Look, I’ve found a couple programs. Which do you want to go with?” I said, “I don’t care. The quickest. Just get us out of this house.”
When Morgan Lumbley came to the Gunnels’ closing today, she brought the note she wrote during her first phone call with them.
Initially, we thought the buyout was going to be done in early 2020. But it kept dragging out. Red tape. Then COVID hit. That changed everything. I would email Morgan nights, weekends, whenever it rained, asking “When?” But never once did she get irritated or say, “I’m doing the best I can.”
All throughout biblical scripture, it says we do not understand His ways or His timing or His plans. If we had been bought out before now, no way would we have gotten the offer we got.
We got full current market value. We hoped the county would pay off the mortgage, which was about $60,000 but FEMA covered full market value…$250,000.
Bob: How did you find these programs, Morgan?
FEMA’s Flood Mitigation Assistance Program
Morgan: There are a couple funding programs for buyouts. The one we got the Gunnels in is FEMA’s Flood Mitigation Assistance Program. It is a “cycle funding” opportunity – available every year. But it’s a competitive grant. So, we have to fill out an application that names the homes you want to buy out – and their values – on the front end. The county collected data for “severe repetitive loss” homes. And when we won the grant, those were the people who got offers.
But buyouts are probably the slowest of all the mitigation processes. So, sometimes people drop out before deals close. And when they do, that opens up room for others.
Bob: Is that how Tammy and Ronnie got in?
Morgan: Yes. Tammy and Ronnie could also have qualified through a HUD program, but we focused on FEMA’s, because they had a current National Flood Insurance Program (NFIP) policy. It was also based on their flood losses. They were considered a “severe repetitive loss.”
Active Flood Insurance Key to Buyout
Not counting our own personal funds, NFIP spent three quarters of a million on that property. They could have bought us out five times.
Tammy Gunnels
Tammy: People said we should just walk away. But we literally had no place to go. When you flood, yeah, you get insurance. But the lien holder on your home gets the money. The lien holder releases it in increments so that you make the repairs. And they inspect the repairs before releasing the next payment. There IS no walking away. Most people don’t understand that. You don’t have money to go anywhere.
We had already drained Ronnie’s 401K and every bit of savings we had. We’re at the age that we’re supposed to be looking forward to retirement. But we don’t. I have nothing left from my kids from when they were growing up. The childhood memories – all those silly little pictures they make for you in birthday cards – I have none of that left. The floods took everything. This has aged us physically and mentally by years.
Ronnie and Tammy as they sign the last of the closing papers.
Ronnie: When we first got insurance, it was fairly cheap and then once we flooded, it skyrocketed. We were just going to handle the losses ourselves. But our neighbor said, “If you’re not insured, you can’t be on any buyout list. That woke us up. We said, “We’ve got to get back on insurance.”
The 13th Time is the Charm
Bob: So Morgan, put this in perspective for me. Flooding 13 times. Where does that rank?
Morgan: 13 is a lot.
Bob: Is it a record?
Morgan: Of those that have come across my desk, it definitely is! Five or six is pretty common, maybe even seven. But 13 is a lot. I think that’s what got me the most. To hear that someone has flooded that many times!
Tammy: Morgan says she’s the low person on the totem pole, but she’s on a throne in my heart forever.
Home Will Be Demolished and Lot Turned to Green Space
Bob: What will Montgomery County do with the home you just bought?
Morgan: Demolish it. The land will be regraded and then it becomes green space to restore the natural flood function. Nothing else. Another residential structure cannot be built on that land.
“I just want to be a normal person again!”
Bob: Tammy, where do you go with your life from here?
Tammy: I don’t think we’ve even thought about it. For the last 13 years, we haven’t been able to plan anything.
Ronnie: We’re just hoping we don’t freak out every time it rains.
Tammy: I just want to go to sleep at night without pacing the floor, wondering when the next flood will hit, and whether the water will come in through the front door, the back door or the patio. I just want to be a normal person again.
Advice for Home Buyers: Research, Ask Right Questions
Bob: What advice would you give people looking for a home to buy?
Morgan: Research! Research is the biggest thing. Diligent research. Too many people take information at face value. They look at the seller’s disclosure. And it asks, “Has the home flooded?” But it doesn’t say when. And it doesn’t say how many times. And no one has to tell you that. Also, the damage amount is not indicated anywhere. And no one has to disclose that either.
If you’re looking at a house, go over to the neighbors. Knock on doors and ask, “Did you flood? Do you know if that house flooded? How high did the water get in your yard? Those are questions that you want to ask.
Ronnie: I’m guilty. I didn’t ask the right questions.
Morgan: A lot of people, when they go looking for their forever home, they’re looking at granite countertops. Is the backyard big enough for the kids? But the questions they really need to ask are, “Am I near a flood plain? Has this house been flooded? How many times? How high? Those kinds of things.”
Tammy: She is exactly right. EXACTLY.

To date, Montgomery County has resisted any mention of a subsidence metric in DFCs for the groundwater management area which includes 14 counties. All must abide by whatever metric the group adopts. The group has been arguing about this metric for years and they’re rapidly approaching a mandatory deadline set by the state.
The Lone Star Groundwater Conservation District (LSGCD) Board which regulates groundwater withdrawals in Montgomery County has favored unlimited groundwater pumping and denied that subsidence affects Montgomery County. Both the southern and northern parts have already seen measurable declines.
Sources close to the controversy do not expect GMA-14 members to reach agreement next week. However, John Martin, head of the management area says, “After we convene and discuss the summary reports submitted by each GCD (a summary of the comments received during the public comment period) the Group will have completed all of the necessary requirements that must be completed prior to the adoption of the DFCs. So, a “final” decision (for this round of planning) could be made at this meeting.”
The Army Corp’s public comment period for adding 1,000 feet of crest gates to the Lake Houston Dam ended on August 23rd. However, I have not yet found any recommendation from the Corps on their site.
The Coastal Water Authority discusses the project at its monthly board meetings.
Minutes from the September meeting have not yet been posted. However, directors did receive an update in their August 11 meeting. The minutes state that engineers presented their modifications of the spillway to support the gates. Next steps (at the time) were to focus on the cofferdam design and structural analysis of the spillway during demolition, interim construction, and post construction.
CWA has not yet responded to an inquiry about how the September meeting went.
Matt Barrett, SJRA’s flood-management director said, “We have not yet selected consultants for the Joint Ops project. My goal would be to start … joint ops by sometime next summer. We are coordinating with CWA/City of Houston on the joint ops schedule to ensure that the project merges as seamlessly and effectively as possible with their ongoing efforts related to the additional Lake Houston gates.”
Makes sense. While FEMA has approved construction of the gates in principle, FEMA has not yet approved the plans. Stephen Costello told a community meeting at the Kingwood Community Center on July 9 that he expects all plans and the environmental study to be completed by the summer of 2022.
The idea is to help people better understand how much water is moving down Winters Bayou, the East Fork, and Peach Creek by adding three gages, one on each at strategic locations.
Barrett says SJRA staff is handling most of this work in-house and has already started.
Locations at both Walnut Creek and Birch Creek have potential to provide flood-mitigation benefits to the watershed. But which to pursue? Here’s the scope of work.
This is another SJRA project. Barrett says, “We recently completed consultant selection and contract negotiation for the Spring Creek project and took the consultant contract to our Board last week (where it was approved). We are aiming for a mid-October start date.”
Location of MoCo projects in San Jacinto River Basin Master Drainage Study
Upper San Jacinto River Basin Sedimentation Study
This SJRA study is also an extension of work started in the San Jacinto River Basin Master Drainage Study. The application for this grant from the state’s Flood Infrastructure Fund states, “Any sedimentation reduction activity in the Upper San Jacinto River Basin (Lake Houston watershed) is anticipated to achieve some level of reduction of sediment load entering Lake Houston, which would in turn reduce storage reduction in the lake, which is the major water supply reservoir for the City of Houston and surrounding communities.”
It could also reduce Lake Houston Area dredging costs which Costello estimates will total $222 million. After taking years to dredge the West Fork, the City is now dredging its way to the East Fork.
Barrett has not yet selected a consultant for the sedimentation project. He hopes to get that started by Spring 2022. The Spring Creek and Joint Operations studies have much shorter timetables, so the SJRA started those first.
Potential vendors interested in developing a long-term dredging plan for Lake Houston had to submit their qualifications by September 23rd last week.
It’s not clear how many vendors responded or who they were. According to Stephen Costello, “It is my understanding that this information is not available due to the quiet period provisions of the city’s procurement process. The information will not be available until the consultant is selected/contract terms negotiated and the contract is on the city agenda for council action.”
That should happen sometime in November. Stay tuned.
Said Barrett, “The Caney Creek project is on hold due to limitations of the CDBG-MIT funding program. Grants for a single project were limited to $100 million in the first round of applications (and the reservoir project as recommended in the San Jacinto Regional Watershed Master Drainage Plan was anticipated to be over $100 million by a decent amount).”
The Texas General Land Office (GLO), which coordinates HUD grants in Texas is committing most of the 2nd round funding to HCFCD after the uproar that followed Harris County’s snub in the first round. Barrett says he is coordinating with appropriate entities to determine how that funding will ultimately be distributed and whether SJRA would be eligible to receive any.

Most of us have seen sinkholes. And most of us have probably given little thought to what causes them.
Retired engineer Chris Bloch, a local flood fighter, measured a 13-foot deep sinkhole near Taylor Gulley earlier this year that had become overgrown with vegetation. Working with the City of Houston and a local homeowner who first reported the problem, they found the sinkhole related to a nearby storm drain.
Bloch lowered this length of PVC pipe into the Taylor Gully sinkhole to measure the depth.Note how the hole had become overgrown with vegetation.
Other things can cause sinkholes, but in this area and in this part of the world, “storm drain gone bad” ranks high on the list of things to investigate.
Corrugated Pipe Commonly Used At Outfalls When Kingwood Built
According to Bloch, when Friendswood built Kingwood, they commonly used corrugated metal pipe (CMP) at storm sewer outfalls. CMP has an expected service life of approximately 35 years, says Bloch. And corrosion commonly causes failure at older outfalls constructed with such pipe.
For example, see the section of pipe below. This photo was taken on Ben’s Branch, not Taylor Gully, but it shows how the pipe rusted, bent, and crimped. Also look just to the right of the wooden posts, and you can even see a large hole in the pipe. It even tilts upward before it reaches the creek.
Bloch frequently walks ditches looking for sinkholes to report to the City. He says he’s aware of at least five right now.
The 72-inch outfall to Taylor Gully serviced drainage area G03408-00-OUT which encompasses all of Greenriver Valley Drive and Mountain Bluff Lane as well as portions of Appalachian Trail, Natural Bridge and Echo Falls Drives. That area comprises 33.4 acres. See below.
Service area for damaged outfall encompasses 33.4 acres where several homes flooded.
The transition from a 72-inch concrete storm sewer to the 72-inch CMP outfall is at a manhole on the edge of the Taylor Gully right of way. See below.
Over the years, the CMP at the connection to the manhole failed. The earth above the failed pipe washed into the outfall and then downstream where it helped reduce the conveyance of Taylor Gully.
Repairs Started But Not Complete
The City of Houston has already repaired several storm sewers with failed corrugated metal outfalls. At least five additional storm sewer outfalls with sinkholes have been identified that have not yet been repaired.
Vegetation frequently hides the presence of these sinkholes. In addition to posing a danger to citizens walking along the banks of the drainage channels, the soil that falls into the sewer can be held up by the corrugations of the metal pipe reducing the flow capacity of the sewer, says Bloch.
Even without obstruction from soil falling into a sewer outfall, the rough surface of the corrugated metal pipe generates greater friction than smooth concrete. The friction slows the flow of storm water and reduces flow capacity which becomes critical during high intensity rains that cause street flooding.
Bloch somehow convinced the City of Houston Public Works Department to replace the damaged CMP at Taylor Gully with concrete pipe. See below.
“This upgrade in the outfall piping will significantly improve the flow capacity of the storm sewer system,” says Bloch.
Concrete pipe replaced CMP at the location of the 13-foot sinkhole on Taylor Gully. Installed by City of Houston Public Works Departmentafter HCFCD repaired Gully.
Concrete Better for New Atlas-14 Rainfall Intensities
When Friendswood Development installed stormwater sewers in Kingwood, they met standards which applied at that time. With new Atlas-14 rainfall projections, we now understand that we should expect more rainfall. Several homes along Appalachian Trial suffered flood damage during Tropical Storm Imelda.
How to Report Sinkholes When You Find Them
As they say, it takes a village to reduce flooding. Now that you know the story behind sinkholes…
If you jog or walk along drainage ditches, exercise caution. Look out for developing sinkholes. And report them to 3-1-1 when you find them. They can pose dangers to children and even grown adults. To put that in perspective, Bloch (shown in the first photo) is more than 6 feet tall, but the sinkhole dwarfs him.
This NBC News story on YouTube has some spectacular examples of sinkholes in Florida along with easy to understand animations that show how they form.
Another 7 minute YouTube video from a series called Practical Engineering focuses on how sinkholes form. It contains both real world examples and table-top experiments that bring the processes to life.

Flood Mitigation Digest: Updates on Nine Lake Houston Area Efforts
Here’s a digest of several efforts relating to flood mitigation in the Lake Houston Area and recent developments.
Subsidence
Groundwater Management Area 14 has another Discussion of Desired Future Conditions (DFCs) on the agenda for its upcoming October 5 meeting. Notice Item #7: “Discussion and possible action regarding the DFCs/Proposed DFCs and the path forward for GMA 14 to accomplish statutory mandates for Round 3 Joint Planning.”
To date, Montgomery County has resisted any mention of a subsidence metric in DFCs for the groundwater management area which includes 14 counties. All must abide by whatever metric the group adopts. The group has been arguing about this metric for years and they’re rapidly approaching a mandatory deadline set by the state.
The Lone Star Groundwater Conservation District (LSGCD) Board which regulates groundwater withdrawals in Montgomery County has favored unlimited groundwater pumping and denied that subsidence affects Montgomery County. Both the southern and northern parts have already seen measurable declines.
Here’s a paper that SJRA presented to the LSGCD board that corrects several LSGCD misstatements and misperceptions. It shows charts and graphs dramatizing the amount of measured subsidence.
Sources close to the controversy do not expect GMA-14 members to reach agreement next week. However, John Martin, head of the management area says, “After we convene and discuss the summary reports submitted by each GCD (a summary of the comments received during the public comment period) the Group will have completed all of the necessary requirements that must be completed prior to the adoption of the DFCs. So, a “final” decision (for this round of planning) could be made at this meeting.”
Projected future subsidence could tilt Lake Houston toward its headwaters because it would affect areas near the county line more than the Lake Houston Dam.
Follow this link to register to attend the meeting on the 5th. That’s next Tuesday from 9:30 AM to 12 PM. GMA 14 uses the GoToWebinar app.
Additional Gates for Lake Houston Dam
The Army Corp’s public comment period for adding 1,000 feet of crest gates to the Lake Houston Dam ended on August 23rd. However, I have not yet found any recommendation from the Corps on their site.
The Coastal Water Authority discusses the project at its monthly board meetings.
Minutes from the September meeting have not yet been posted. However, directors did receive an update in their August 11 meeting. The minutes state that engineers presented their modifications of the spillway to support the gates. Next steps (at the time) were to focus on the cofferdam design and structural analysis of the spillway during demolition, interim construction, and post construction.
CWA has not yet responded to an inquiry about how the September meeting went.
Joint Lake-Operation Plan Development
The SJRA received a grant to develop a joint operation plan for the dams at Lake Conroe and Lake Houston. This will involve the SJRA working with the Coastal Water Authority.
Matt Barrett, SJRA’s flood-management director said, “We have not yet selected consultants for the Joint Ops project. My goal would be to start … joint ops by sometime next summer. We are coordinating with CWA/City of Houston on the joint ops schedule to ensure that the project merges as seamlessly and effectively as possible with their ongoing efforts related to the additional Lake Houston gates.”
Makes sense. While FEMA has approved construction of the gates in principle, FEMA has not yet approved the plans. Stephen Costello told a community meeting at the Kingwood Community Center on July 9 that he expects all plans and the environmental study to be completed by the summer of 2022.
Flood Early Warning System
The SJRA also applied for and received a grant to develop a Flood Early Warning System for San Jacinto County.
The idea is to help people better understand how much water is moving down Winters Bayou, the East Fork, and Peach Creek by adding three gages, one on each at strategic locations.
Barrett says SJRA staff is handling most of this work in-house and has already started.
Spring Creek Flood-Control Reservoir
The purpose of this project is to perform a conceptual engineering feasibility study of two potential dams/reservoirs within the Spring Creek watershed. This is a the next phase of the Spring Creek Siting Study which came out of the San Jacinto River Basin Master Drainage Study.
Locations at both Walnut Creek and Birch Creek have potential to provide flood-mitigation benefits to the watershed. But which to pursue? Here’s the scope of work.
This is another SJRA project. Barrett says, “We recently completed consultant selection and contract negotiation for the Spring Creek project and took the consultant contract to our Board last week (where it was approved). We are aiming for a mid-October start date.”
Upper San Jacinto River Basin Sedimentation Study
This SJRA study is also an extension of work started in the San Jacinto River Basin Master Drainage Study. The application for this grant from the state’s Flood Infrastructure Fund states, “Any sedimentation reduction activity in the Upper San Jacinto River Basin (Lake Houston watershed) is anticipated to achieve some level of reduction of sediment load entering Lake Houston, which would in turn reduce storage reduction in the lake, which is the major water supply reservoir for the City of Houston and surrounding communities.”
It could also reduce Lake Houston Area dredging costs which Costello estimates will total $222 million. After taking years to dredge the West Fork, the City is now dredging its way to the East Fork.
Barrett has not yet selected a consultant for the sedimentation project. He hopes to get that started by Spring 2022. The Spring Creek and Joint Operations studies have much shorter timetables, so the SJRA started those first.
The grant application states that this study could take up to four years, though the SJRA hopes to complete it faster.
Long-Term Dredging Plan Development
Potential vendors interested in developing a long-term dredging plan for Lake Houston had to submit their qualifications by September 23rd last week.
It’s not clear how many vendors responded or who they were. According to Stephen Costello, “It is my understanding that this information is not available due to the quiet period provisions of the city’s procurement process. The information will not be available until the consultant is selected/contract terms negotiated and the contract is on the city agenda for council action.”
That should happen sometime in November. Stay tuned.
SJRA CDBG-MIT Caney Creek Grant
The SJRA also applied for a HUD Community Development Block Grant for Mitigation from the US Department of Housing and Urban Development (HUD). The purpose was to develop a Caney Creek Reservoir Upstream of FM 1097.
Said Barrett, “The Caney Creek project is on hold due to limitations of the CDBG-MIT funding program. Grants for a single project were limited to $100 million in the first round of applications (and the reservoir project as recommended in the San Jacinto Regional Watershed Master Drainage Plan was anticipated to be over $100 million by a decent amount).”
The Texas General Land Office (GLO), which coordinates HUD grants in Texas is committing most of the 2nd round funding to HCFCD after the uproar that followed Harris County’s snub in the first round. Barrett says he is coordinating with appropriate entities to determine how that funding will ultimately be distributed and whether SJRA would be eligible to receive any.
Forest Cove Golf Course Redevelopment
This doesn’t exactly fall into the category of flood mitigation efforts, but Ron Holley today reportedly withdraw his application to the CoH Planning Commission to replat the Kingwood Cove Golf for single family homes. The City of Houston Public Works department requested more details on the drainage analysis which raised many questions.

Sinkholes Often Sign of Damaged Storm Drains
Most of us have seen sinkholes. And most of us have probably given little thought to what causes them.
Retired engineer Chris Bloch, a local flood fighter, measured a 13-foot deep sinkhole near Taylor Gulley earlier this year that had become overgrown with vegetation. Working with the City of Houston and a local homeowner who first reported the problem, they found the sinkhole related to a nearby storm drain.
Other things can cause sinkholes, but in this area and in this part of the world, “storm drain gone bad” ranks high on the list of things to investigate.
Corrugated Pipe Commonly Used At Outfalls When Kingwood Built
According to Bloch, when Friendswood built Kingwood, they commonly used corrugated metal pipe (CMP) at storm sewer outfalls. CMP has an expected service life of approximately 35 years, says Bloch. And corrosion commonly causes failure at older outfalls constructed with such pipe.
For example, see the section of pipe below. This photo was taken on Ben’s Branch, not Taylor Gully, but it shows how the pipe rusted, bent, and crimped. Also look just to the right of the wooden posts, and you can even see a large hole in the pipe. It even tilts upward before it reaches the creek.
Taylor Gully Sinkhole One of Many In Area
Bloch frequently walks ditches looking for sinkholes to report to the City. He says he’s aware of at least five right now.
The 72-inch outfall to Taylor Gully serviced drainage area G03408-00-OUT which encompasses all of Greenriver Valley Drive and Mountain Bluff Lane as well as portions of Appalachian Trail, Natural Bridge and Echo Falls Drives. That area comprises 33.4 acres. See below.
The transition from a 72-inch concrete storm sewer to the 72-inch CMP outfall is at a manhole on the edge of the Taylor Gully right of way. See below.
Repairs Started But Not Complete
The City of Houston has already repaired several storm sewers with failed corrugated metal outfalls. At least five additional storm sewer outfalls with sinkholes have been identified that have not yet been repaired.
Vegetation frequently hides the presence of these sinkholes. In addition to posing a danger to citizens walking along the banks of the drainage channels, the soil that falls into the sewer can be held up by the corrugations of the metal pipe reducing the flow capacity of the sewer, says Bloch.
Even without obstruction from soil falling into a sewer outfall, the rough surface of the corrugated metal pipe generates greater friction than smooth concrete. The friction slows the flow of storm water and reduces flow capacity which becomes critical during high intensity rains that cause street flooding.
Bloch somehow convinced the City of Houston Public Works Department to replace the damaged CMP at Taylor Gully with concrete pipe. See below.
“This upgrade in the outfall piping will significantly improve the flow capacity of the storm sewer system,” says Bloch.
Concrete Better for New Atlas-14 Rainfall Intensities
When Friendswood Development installed stormwater sewers in Kingwood, they met standards which applied at that time. With new Atlas-14 rainfall projections, we now understand that we should expect more rainfall. Several homes along Appalachian Trial suffered flood damage during Tropical Storm Imelda.
How to Report Sinkholes When You Find Them
As they say, it takes a village to reduce flooding. Now that you know the story behind sinkholes…
If you jog or walk along drainage ditches, exercise caution. Look out for developing sinkholes. And report them to 3-1-1 when you find them. They can pose dangers to children and even grown adults. To put that in perspective, Bloch (shown in the first photo) is more than 6 feet tall, but the sinkhole dwarfs him.
For More Information about Sinkholes
I highly recommend:
The US Geological Survey has an in-depth discussion of different types of sinkholes in different parts of the country and how each forms. This is geared toward students in science classes.
This NBC News story on YouTube has some spectacular examples of sinkholes in Florida along with easy to understand animations that show how they form.
Another 7 minute YouTube video from a series called Practical Engineering focuses on how sinkholes form. It contains both real world examples and table-top experiments that bring the processes to life.
