Tropical Storm Predicted to Make Landfall on Saturday; Rainfall Estimates Increased

The National Hurricane Center (NHC) has begun advisories on Tropical Depression 8 in the central Gulf of Mexico. Tropical Storm Watches have been issued for the Texas coast from Port Mansfield to High Island including Matagorda and Galveston Bays.

Recent model guidance brings the system to the Texas coast with 48-60 hours over the Gulf waters. Some show the system over Gulf water for 72 hours as the system slows near the coast. NHC forecasts a 45mph tropical storm slamming the middle Texas coast on Saturday. 

Houston should be on the dirty side of the storm.

If this does reach tropical-storm strength, it would be named Hannah. Ironically, another H storm hit Houston called Harvey in 2017. But Harvey happened a full month LATER in the season.

Next USAF reconnaissance flight will depart at 4:45 a.m. CDT tomorrow morning and will determine if a tropical depression or tropical storm has formed.

Rainfall

Jeff Lindner, Harris County meteorologist, says predicted rainfall rates have increased. Widespread rainfall amounts of 3-5 inches will be possible along and generally south of HWY 105 with higher isolated totals. North of HWY 105 rainfall amounts of 1-3 inches will be possible. There is likely to be swaths of higher rainfall amounts where training bands develop, but where this may occur is difficult to pinpoint at this time range.  

Channel 13 tonight predicts that some areas west of Houston could record a three day total of 14-15 inches of rain because of the slow speed of the storm.

Deadlines Converging on Woodridge Deal; Option If Purchase Falls Through

Several deadlines are converging to force a decision on whether to purchase Woodridge Village from Perry Homes and turn it into a giant regional detention pond. Every day that passes makes that deal appear more remote for reasons I will discuss below. Luckily, Elm Grove residents have an option, which I will discuss at the end of this post. But first…

Deadline #1: Detention Ponds Nearing Completion

Contractors for Perry Homes have nearly finished all detention ponds on the site. Last week, they were cementing drainage pipes and pilot channels in place.

Looking north across the western boundary of Woodridge Village and the massive N2 detention pond on 7/12/2020. N2 has 57% of the detention capacity for the entire site.

Contractors also appeared to be building drainage swales designed to intercept runoff and channel it toward the detention ponds.

Drainage swales, looking east along northern boundary of Woodridge Village on 7/12/2020

These swales were Item #6 on J. Carey Gray’s 10/17/19 letter to the City of Houston Attorney, Ronald Lewis.

Gray is the lawyer for Figure Four Partners, Perry’s development subsidiary. In the letter, Gray promised the last item would be completed in 280 days. 280 days from the date of the letter (October 17th, 2019) is July 24 – this coming Friday.

Perry has said that it would not start building homes and roads until they finished work on detention ponds. With that work done, how much longer will they delay?

Deadline #2: 75 Days from County’s Redefining of Deal

Last week, Houston Mayor Pro Tem Dave Martin addressed the Kingwood Executive Group. He said that after the May 19th Commissioners Court meeting in which Commissioners redefined the terms of the purchase, Perry sent a letter saying “you have 75 days or we will sell the property.”

75 days from May 19th is August 2nd.

The City applied for a grant from the TWDB to help pay for its half of the purchase/construction costs. However, the TDWB doesn’t expect to finalize decisions on those until this winter.

Deadline #3: Upcoming Commissioners Court Meeting

The next Harris County Commissioners Court Meeting is July 28th. They don’t meet again until August 11. Precinct 4 Commissioner Jack Cagle is placing an item on the agenda for next Tuesday to discuss the status of the purchase.

Deadline #4: Perry Says It Has Offer Waiting in Wings

At the same meeting of Kingwood executives, Mr. Martin reported that Perry said it had an offer to buy the property. But he also questioned how firm the offer could be, given all the pending litigation.

Deadline #5: Peak of Storm Season Approaching

Nature always gets the last say. Nature could make everyone involved in this deal look bad if Elm Grove and North Kingwood Forest flood again.

We’re now approaching the peak of hurricane season. Beginning in August, storms start to build rapidly. They peak on September 10. See below.

Number of Storms by Date for the last hundred years. Source: NOAA

We have two storms approaching now. One south of Louisiana. The other still in the mid-Atlantic.

Based on satellite and surface observations, a broad surface low pressure center has formed with the tropical wave moving into the central Gulf of Mexico. NHC has increased the chance of formation to 80% and advised that watches and/or warnings could be issued for portions of the TX and LA coast tonight or on Thursday.

Overall, says the National Hurricane Center (NHC), the organization of the system off the Texas coast is increasing and it is likely that a tropical depression or storm will form in the next day or two as the system moves generally toward the WNW around 10mph.

Jeff Lindner, Harris County meteorologist predicts it “could drop 1-3 inches with isolated totals of 4-6 inches. Heaviest rains may end up close to the coast, say south of a line from High Island to Wharton. There’s still much uncertainty, although visible images this morning show a better organized system in the Gulf.”

Latest satellite images show storm in Gulf building.
Gonzalo, the Atlantic storm now looks like it will track into the Caribbean by Sunday and turn into a hurricane.

The second storm intensified this morning and was given the name Gonzalo. According to Lindner, Gonzalo may weaken as it moves across the Caribbean Sea if it encounters wind shear. So forecasters have low confidence in intensity predictions. However, “small systems such as Gonzalo can have rapid fluctuations in intensity,” says Lindner. And most models agree on the path.”

Nature, as they say in poker, could soon call everyone’s hand.

Option if Deal Does Not Happen

The amount of detention that Perry has built is 40% short of Atlas 14 guidelines for this area. What happens if the Woodridge Village purchase falls through? Is it the end of Elm Grove? Not necessarily.

Residents have a fallback. Harris County Flood Control could widen and deepen Taylor Gully. Engineers have reportedly studied that option as part of the Kingwood Area Drainage Analysis, due out in September.

However, widening and deepening Taylor Gully could take some time. And there is intense competition for resources right now. That option could not be constructed in time to head off storms for this hurricane season. So keep your fingers crossed.

More West Lake Houston Parkway Bridge Repairs Scheduled

This post is a bit off topic but it does relate to Hurricane Harvey. Harvey damaged the West Lake Houston Parkway bridge. So you can add this to the list of the area’s damages from Harvey.

Houston Public Works will conduct its final 5-month-long bridge repair project on the West Lake Houston Parkway Bridge beginning Monday, August 3. The project consists of repairing bents 25-28 underneath the bridge. 

What is a Bent?

A “bent” is the combination of the cap and piles. They act as supports for the entire bridge. Here’s an easy-to-read and well illustrated primer on bridge inspection that describes the purpose of bents. (See photo below of the West Lake Houston Parkway Bridge bents.)

Bents underneath the West Lake Houston Parkway Bridge. Photo taken 9/16/2018, one year after Harvey. Note the flood debris still caught in the bents. This is a random photo and not intended to show the damaged bents.

Cost More than $4 Million

The cost of the project is $4,385,197 and will be funded through the Dedicated Drainage and Street Renewal Fund. The contractor for the project is NBG Contracting, Inc. The work is expected to be completed by Saturday, January 9, weather permitting.

Road Closures and Schedule

On Monday, August 3, work will begin at 7:00 a.m. by closing the outer lanes of the bridge. Two-way traffic will be maintained on the inner lanes. Construction activities are expected to take place Monday through Friday from 7:00 a.m. to 7:00 p.m. Crews will occasionally work from Sunday at 5:00 p.m. though Monday at 5:00 a.m. when work requires closure of one side of the bridge. During these occasional work hours, pedestrian sidewalks along both sides of the bridge will be barricaded and closed for safety.

Please be aware of flagmen and orange traffic cones in place on-site assisting with traffic flow through the construction zone. All lanes of the bridge and pedestrian sidewalks will reopen following the completion of the project on Saturday, January 9, weather permitting.

This project follows the completion of repairs done by Houston Public Works this spring and the temporary repairs last October after three bearing pads slipped from their concrete beams. The work completed this month are the final repairs needed for the bridge to ensure the longevity of the infrastructure. 

For more information, please contact Mayor Pro Tem Martin’s office at (832) 393-3008 or via email at districte@houstontx.gov.

Get Ready for the Rain Train

Forecasters predicted a higher than average hurricane season. We will find out whether they are right in the next three months – the peak of the season. But the rain train has already started.

Other Storms Already Stacking Up in Atlantic

Meanwhile, two more storms are stacked up out in the Gulf and Atlantic. (See below.) The National Hurricane Center gives the orange one a 40% chance of developing and red one a 90% chance in the next five days.

As of 6:30 PM on 7/21/2020 the NHC has upgraded the central Atlantic Storm to a tropical depression, likely to enter the Caribbean this weekend. Source: NOAA
One model has the storm building into a hurricane. However, most don’t at this time. The intensity forecast for days 4-5 is low confidence according to Jeff Lindner, Harris County meteorologist.

Tropical Wave Likely to Arrive Friday

NOAA says that a tropical wave currently over Cuba is producing a large area of disorganized showers and thunderstorms over western Cuba. NHC expects this system to reach the northwestern Gulf on Thursday and Friday. Tropical formation chance currently equals 40 percent.

Jeff Lindner, Harris County meteorologist, says, “Regardless of development, widespread showers and thunderstorms will begin to impact the upper TX coast as early as late Thursday evening. More likely the impact will be Friday and lasting into Saturday. Some of this rainfall will be heavy. Winds will increase into the 15-25kt range with seas building to 3-5 feet by late Thursday and likely higher on Friday.”

90% Chance of Formation for Atlantic Storm

NHC also expects that system midway in the Atlantic (now Tropical Depression 7) to get better organized. However they also say that less favorable conditions could limit additional development of the system by the weekend. Formation chance: 90 percent.

Here’s how it all looks on the GOES-East satellite imagery in earth colors. Note the system about to enter the Gulf and the steady stream of clouds rolling off the western coast of Africa and across the Atlantic.

Note clouds over western Cuba and another mass starting to spin in mid-Atlantic.
Closer shot with land masses outlined.

I nicknamed the steady stream of clouds “the rain train.”

Trade Winds Powered Global Commerce for Centuries

Technically, though, they’re called the trade winds. The term has an interesting origin. For centuries, they powered trade between Europe and the Americas. This time of year, sailors from Europe heading to the Americas would first sail south to Western Africa. There, they would pick up the trade winds (visible in the photos above) that powered them west.

After completing their trade, they would head north along the Eastern Coast of the U.S. and pick up a return flow that would take them back to Europe.

It was a reliable, but often deadly route.

Of the 691 ships identified by the Spanish researchers that were lost between between 1492 and 1898, 91.2% were sunk by severe weather – mainly tropical storms and hurricanes.

Without satellites, hurricanes often caught them by surprise. The storms could snap their masts, at which point they would be “dead in the water.”

There’s an island off the coast of Honduras called Guanaja. The Spanish called it Isla de Los Pinos. Isle of Pines. It’s one of the few islands in the Caribbean with native pine trees. Columbus visited there on his fourth voyage. And according to local legend, Spanish sailors would often stop there after crossing the Atlantic to replenish their masts.

TCEQ Complaints Against Texas Concrete Plum Grove Plant Still Unresolved

On July 14, 2020, the TCEQ completed another investigation into the Texas Concrete Plum Grove Plant. The investigator confirmed that it remains in violation of stabilization requirements before abandonment.

Small part of an estimated 15 acres still without vegetative cover. Photo taken 7/19/2020.

Moreover the company still has not removed rusting equipment.

Excavator and fork lift parked near entrance on 7/19/2020

13 Previous Investigations

TCEQ investigated the plant 13 previous times in the last five years.

The Texas Concrete Plum Grove Plant was already part of an active enforcement case (#57254) due to an unauthorized discharge and for failing to meet final stabilization requirements before terminating coverage under the Texas Discharge Pollutant Elimination System (TPDES).

“Due to the severity of the unauthorized discharge and the facility’s history of past noncompliance, this case will be referred to the Enforcement Division,” said the TCEQ in its report of a September 24, 2019, investigation.

Meaning of “Final Stabilization Requirements”

Final stabilization requirements include the planting of “vegetative cover” to retard erosion before abandoning the site. Texas Concrete ceased operations at the site and pulled down its signs. However, approximately 15 acres of the site remain unplanted; they have no vegetation.

According to the TCEQ report, the company claims it planted grass, but the grass failed to establish. A company spokesperson was not available for comment.

The definition of final stabilization is as follows: “All soil disturbing activities at the site have been completed and a uniform (e.g. evenly distributed, without large bare areas) perennial vegetative cover with a density of 70% of the native background vegetative cover for the area has been established on all unpaved areas and areas not covered by permanent structures, or equivalent permanent stabilization measures (such as the use of riprap, gabions, or geotextiles) have been employed.”

TCEQ did not respond to a request for an explanation of how it measured 70% of the native background vegetative cover. Background vegetation is this case is a dense pine forest, not grass.

Rusting Equipment Allegedly Sold, But Still on Site

The company also seemingly abandoned rusting equipment on the site. The equipment includes a dredge, excavators, front loaders, dump trucks and trailers. Since the TCEQ’s followup investigations in June 2020, the company removed several dump trucks, but the vast majority of the other equipment remains – despite assurances from the company that it had all been sold. Neither the TCEQ, nor Texas Concrete has volunteered when the company will remove the equipment.

Weeds growing around tanker testify to how long it has remained there. 7/19/2020
Dredge still on site as of 7/19/2020
Cyanobacteria have taken over some of the ponds at the abandoned Texas Concrete Mine. 7/20/2020. The pond was not tested for cyanotoxins.

No Additional Leaks Found

There is some good news from the latest investigation. Texas Concrete plugged previous breaches in its dikes. The investigator did not find any new unauthorized discharges, or discharges that failed to meet water quality specs.

Approaching Peak of Hurricane Season and Year Wasted

Still, three tropical disturbances making their way across the Atlantic at this moment make a stark reminder of why abandonment requirements exist. This site has sat unused for approximately a year. That should have been plenty of time to establish grass at a minimum and to restore this site.

Texas Concrete brags that it is a member of TACA and that TxDoT is one of its customers.

If the State of Texas is serious about enforcing environmental regulations, now would be a good time to start. And this would be a good place.

The only thing that separates neighborhood kids from playing in the sand, climbing on the equipment, and swimming in the colorful water. The security guard sign is a bluff.

Three Online Tools To Help You Better Understand Flood Risk

Hopefully, by now, regular readers of this website should know all about FEMA’s National Flood Hazard Layer Viewer and be able to identify whether they are in a recognized flood zone. But fully understanding flood risk can be far more complicated.

In a heavy rain, will water run toward or away from your home? Exactly how far below the 500-year flood plain is a given location? When water at a river gage reaches X, how much water will you be standing in at Y?

Every week, people alert me to new online tools that help assess different aspects of flood risk. Last week, I learned about three.

Elevation Profiling in Google Earth Pro

One is actually a feature within Google Earth Pro called “Elevation Profiling.” Many parts of Houston are so flat, it’s often hard to tell with the naked eye whether your home is at the high point or low point in your neighborhood. Which way does the land slope? How steep is the grade? What are the average and maximum grades? These are all good things to know if you want to make sure you don’t buy at the bottom of a bowl or waterfall.

For yesterday’s post about a family that flooded in North Kingwood Forest, I checked the elevation profile between various points in Woodridge Village and their neighborhood.

From the NW corner of Woodridge Village to the home on Right Way, the elevation dropped approximately 16 feet. The average slope is 1.4%.

Elevation dropped 15 feet along the eastern border of Woodridge, 12 feet along the western border and 3 feet from west to east along Taylor Gully. No matter which way you look at it, everything on Woodridge sloped in their direction.

To use this feature in Google Earth Pro:

  • Select the Path tool.
  • Define a path. It can contain multiple points. For instance, you might want to trace the elevation along street that curves.
  • Highlight the path in the side bar.
  • In the Edit menu, select “Show Elevation Profile.”
  • The red box will then appear at the bottom of the screen with the profile and related information.
  • Running your cursor across the elevation profile will highlight the corresponding point on the satellite image and show you its elevation, distance from the start, and grade from the start.

Houston Public Works Floodplain Map

Houston Public Works Floodplain Map

Houston Public Works offers a variation on FEMA’s floodplain maps. It shows you in one foot increments how far below the 500-year floodplain (the City’s new benchmark for building) you are at any given location in the City. Are you barely in it? Or more than five feet below it? Knowing the answer can help you assess how much risk you’re taking on when you buy a new home. Said another way, it gives you much more detail.

National Weather Service Inundation Viewer

Want to know how deep the water will be in your home when a river gage near you reaches a certain level? This is the tool for you.

Gage is at the green marker. Click on any point in the blue, and it will tell you how deep water will get at that point for a selected gage height (left).

Start by clicking on Inundation and a gage height in the left hand column. As you click on different levels, watch the floodwaters expand or contract. (This shows the extent of floodwaters when the gage is at 66 feet.) Then click on another point within the floodwaters. A pop up box tells you how deep the floodwater will get at that location.

As you click on different gage heights in the left column, watch the water increase or decrease within the pop up box. At a gage height of 78 feet, people at the red dot could expect to be under 12 to 14 feet of water.

This viewer is not available for all gages. However, it is available for two in the Lake Houston Area. The two are at US59 on the West Fork and FM1485 on the East Fork. There are five others in the Houston region.

Here’s how it works:

  • Locate your gage then click on Inundation in the left column.
  • Next, select a level of flooding.
  • Within categories (Minor, Moderate, Major), you can select one foot increments.
  • Then on the map, click on any other nearby location.
  • Within a pop-up box, it will tell you how much water you can expect for any given gage height.
  • This information will be useful in deciding when and whether to evacuate. For instance, clicking on a bridge will tell you at what point it goes under water.

Clicking on other tabs, will show you hydrographic and probability information, and more.

I look forward to the expansion of this powerful tool to other gages.

The First Responder During Harvey Who Flooded During Imelda

This is the story of a first responder who helped rescue dozens of families during Harvey. His own home later flooded during Imelda. Then he was the one calling for help. But that’s just the start of this gripping story. A house he rented (next to Woodridge Village) had flooded months earlier in May 2019, but Camillo Properties, the management company, said it had not. Within days of moving in last September, it flooded again. And that was after being in the emergency room most of the previous night with his stepson, who was diagnosed with pneumonia. Then the management company sued him for non-payment of rent – which he had paid. You don’t want to stand next to this guy in a lightning storm. Despite all his troubles, though, he says his relationship with his fiancé is stronger than ever. For job reasons, he needs to remain anonymous. I will refer to him only as John.


Rescue of Friend Turns into 12-Hour Marathon

Rehak: You had worked for a fire department in Montgomery County before Harvey. During the storm, you got a call from a terrified friend in the Barrington who was trapped in rising floodwaters. Tell me what happened.

John: Six to eight hours before calling me, she posted to Facebook saying she was in her living room, watching a movie, sipping wine, and “Everything is normal.” Then she called at 2 a.m. asking if I had any contacts who could rescue her.

Every back-channel contact was overwhelmed. So, I went down there in my Jeep to see if I could make it in. When I arrived, it was a lot deeper than I thought. Then a gentleman showed up with a huge aluminum boat – the kind that HFD uses for water rescues. 

He said, “Hey, I’ve got a couple of friends back here, too. Let’s go see what we can find.” This was just before dawn. We got everyone into the boat. Then we started looking and realized, “It’s not just a few people who didn’t evacuate.” There were hundreds upon hundreds back there.

That’s about when rescue organizations started showing up. Eventually, there were dozens of boats pulling people out.

Rehak: How many times did you go back in?

John: I couldn’t say. But I didn’t leave till about four that afternoon.

Rehak: You evacuated people for 12 hours!

John: We had to stop when we ran low on fuel.

Rehak: Could you estimate the speed of the current in the Barrington?

John: No. But I’ll tell you that it got real hairy, real quick, even with a 150 horsepower motor. 

Delayed Emotional Impact and Navigating Hidden Dangers

Rehak: What was it like emotionally as the day wore on?

John: After the fact, it was like…”Holy crap! How many people just lost everything that they had?” But at the time, we were too busy to think about it.

Coast Guard Rescue in Barrington filmed by John during boat rescue.

John: Coast Guard Seahawks were doing hoist rescues in areas boats couldn’t get to. And we were dodging submerged obstacles. We hit a couple of communal mailboxes. Those aren’t typical hazards you think about when operating a boat.

Rehak: Were there any other dangers that made things hairy?

John: Desperate people. Many weren’t thinking clearly. Some families didn’t want to leave, including those with kids.

Rehak: Were they in two-story homes?

John: Yes. But they had no access to resources past the initial push. Food, fresh water, working toilets.

Rehak: It was unsafe.

John: And water was creeping up to power meters. CenterPoint had not yet killed the area.

Rehak: Were there cars under water, too?

John: Oh, yeah. You could barely see the tops of some. 

Rehak: Any other stories stand out in your mind? 

John: Some families with kids had to make decisions about who would get in the lifeboat first and who would stay behind. It was heartbreaking.

“No. No. No. That House Never Flooded”

Rehak: Let’s talk about YOUR flood experience now in September of 2019 during Imelda.

John: We had been leasing an apartment at the front of Kingwood. The lease was coming up for renewal. So, we started looking at houses to lease and found one in North Kingwood Forest. It looked brand new even though the neighborhood was several years old. Looking back, that should’ve been a red flag. 

Camillio owned many properties on the street where John lived. Photo taken 12/22/2019, after homes had been repaired from Imelda on 9/19/2019.

Rehak: What attracted you?

John: It had more space. It was affordable, and there were many young families with kids. We applied, were approved within a couple of days, and set a move in date. As luck would have it, that turned out to be just SEVEN days before Imelda.

Rehak: Your pictures looked as though you weren’t even fully unpacked when the flood hit. 

Still unpacking after move when flood hit.

John: We had only unpacked essentials. And we had just done a big Costco run with cases of water, six-packs of chili, everything you need to stock a pantry. And then…

Rehak: Before you signed the lease, did you ask whether this place flooded before?

John: Unfortunately, we asked just after signing. My dad talked to our neighbor next door when we were moving in. She asked him whether they told us that the house had flooded in May.

View of street from John’s garage during Imelda

Rehak: Surprise!

John: So, I called the landlord and asked, “Did that house ever flood?” I was told, “Oh, no, no, no. That never flooded. Only the other side of the neighborhood flooded.”

8 days after the flood

Relocation to Spring Triggers Landlord Lawsuit

Rehak: Did that become a point of contention between you and the owners?

John: Not immediately. The landlord offered us another place in Spring. It seemed like they were trying to be accommodating. So, I didn’t really call out their lie at the time.

Rehak: What happened later to change your mind?

John: Towards the end of October, beginning of November, we got a letter from them saying that we had not paid our rent at the Spring location. Of course, we had, so I called them and said, “Hey, this is an error.” I sent them copies of bank statements showing the rent payments cleared. We had even paid through their online portal. They said, “OK, we’ll look into it.” 

Fast forward, two weeks later, a Constable serves us with an eviction lawsuit. This was a couple months after losing 70 percent of everything we owned.

Rehak: What did you do?

John: I contacted an attorney friend and he began calling them. They fed him the same line, “Oh, we will need to look into it.”

My attorney called me two days before court and said, “I have not gotten any response from them. We’ll have to go to court.” 

There, we met Camillo’s representative from Nationwide Evictions. We showed her our bank statements. But their paperwork showed only a move in and then nothing being paid. The judge found our evidence overwhelming and ruled in our favor. That was the end of that. But it left a sour taste. 

At that point, I thought to myself, “As soon as our lease is up and we can get away from this management company, we’re going to.” And we did.

Impact on Relationship

Rehak:. You have a fiancé who is a paramedic. How did this affect your relationship? 

John: I tell people, “After two moves in 10 days, on top of a flood, you’re either going to split up or you’re going to last a lifetime. We’re still together! 

Trip to Emergency Room Night Before Imelda

John: To top it off, the night before Imelda, he developed pneumonia. We were in the Kingwood Emergency Room with him until the wee hours. Fast-Forward to 9:30 or 10 the next morning. My fiancé woke me up and said, “We’re flooding.” 

View out front door when John woke up.

Rehak: What went through your mind?

John: I felt this has got to be a nightmare. That’s what she told to me later – that I rolled out of bed half awake and said, “This has got to be a nightmare.” Then I stepped down into water. That woke me up real fast!

From Pneumonia to “Water Park”

John: You’d think my stepson would have been sad or scared. But like a typical 4-year old, he thought it was a freakin’ WATER PARK! I can’t help but think that contributed to his pneumonia. It took him two weeks to get over that. There were a lot of sleep-deprived nights for us. We were mentally drained.

Rehak: So, on top of the flood, you’ve got a sick kid during your second move in two weeks! How did the people at your workplace react?

John: They came together. I have to say. They gave me time off work. They established a “go fund me.” Financially, they took care of us. They did right by us. 

“Start Taking Out Fence Pickets”

Rehak: Tell me more about what happened during the Imelda flood after you woke up.

John: We reached out to family and friends and started stacking things on couches, countertops, anything to get stuff up off the floor. Then we called Camillo and said, “We are actively flooding. What do we do?”

She said to start taking out fence pickets to allow the water to flow around the house versus through the house. That’s when I suspected that they knew this house had a tendency to flood. Otherwise, why would you say, “Take out fence pickets”?

Water Coming From Back, Not Street

Rehak: Your video shows water flowing quickly from the back yard toward the street. How deep was the water in your back yard?

John: About a foot above my knees. It was that much higher in the back than on the street side. There was sand and silt throughout the house after the water receded.

Rehak: That didn’t come from the street.

John: Nope. There was only one place it could have come from. The 268-acres they had just cleared next to us.

1054 Days after Hurricane Harvey

City of Houston Will Now Require Developers to Identify Flood-Prone Areas on Their General Plans

It’s a minor victory. And it may not actually change anything on the ground. But the City of Houston today sent a signal to developers, who now have to identify flood prone areas on their general plans.

The move should eliminate any doubt among bankers, buyers and real estate agents as to whether a particular property is in a floodway or flood plain.

By following all the other guidelines, developers can still get their plans approved. This change helps people seeking truth and full disclosure in the sales process.

There’s one other key change. Another new requirement is that, as each section of a general plan is platted, it has to adhere to the then current standards. That is important so that the entire development isn’t grandfathered by the approval date of the general plan.

These changes may make some developers think twice about buying and developing flood-prone property. Especially if they target unknowledgeable buyers, such as young people or foreigners, who may be unfamiliar with American flood standards.

Today’s press release by the City of Houston’s Planning and Development department says the changes will go into effect July 24, 2020.

The release is being blasted out to developers also. It’s titled “Platting Updates for Flood Prone Areas.” I have reprinted the full text verbatim below.


IDENTIFICATION OF FLOOD PRONE AREAS ON GENERAL PLAN

Effective July 24, 2020

Flooding events have been increasingly severe in the City of Houston and our region. The 2018 amendment to Chapter 19 City of Houston Code of Ordinances mandated that it was necessary to evaluate development within the 100-year and 500-year floodplains to protect investments made by residents and business owners in real property within the City. Harris County and others have developed their own needs in improving the drainage in their regions.

To mitigate and reduce the risk of flood loss for future development, the 100-year, 500-year floodplains and floodway will be required to be identified on all General Plans submitted to the Department with the Plat Tracker application. Applicants will be required to graphically depict the location of the floodplains and or floodway on their General Plans and provide related note.

This information must be provided as part of initial submittal of a General Plan for Planning Commission consideration. The General Plan application will be marked incomplete if this information is not included as part of the initial submittal.

HOW TO ILLUSTRATE

The way to depict this information correctly is to go to the FEMA website through the following link: https://msc.fema.gov/portal/search#searchresultsanchor.Enter the address, place, or coordinates. The site will produce a map that will identify whether the property is located in the 100-year, 500-year flood plains or floodway. Provide a dashed line on your General Plan identifying the 100-year, 500-year flood plains or floodway as depicted on the FEMA map.

GENERAL PLAN RELATED NOTE

Also, include on the face of the General Plan the following related note as follows: Portions of the property included in this General Plan lie within the known floodway and the 100 and 500-year floodplains. As each section or parcel is platted and developed, the then-current standards of City of Houston [or if ETJ: Harris County] drainage, elevation, and building regulations must be adhered to. 

DISTRIBUTION

This document is being circulated to our customer eblast and posted on our Development Services web page https://www.houstontx.gov/planning/DevelopRegs/..

For additional information contact Dipti Mathur at 832-393-6560.


Imagine how the general plan of “Orchard Seeded Ranches” would look. It would clearly show that virtually every property was subject to severe flooding. Also imagine now how those new townhomes in Kings Harbor will look to Chinese investors.

Developers who specialize these types of distress properties may have to rethink their marketing strategies.

How High Water Marks Help Fill Gaps in Flood Knowledge

Note: the post below was condensed and adapted from a longer USGS article. The U.S. Geological Survey (USGS) records continuous stream stage (height of a river) and streamflow (how much water is flowing) with thousands of gages throughout the nation. But how can they determine flood height where no gages exist?

Simple, USGS correlates high water marks after floods with peak gage heights during floods.

“If, for example, records show that stream stage reached 17 feet during a storm, a high-water mark will show the hydrologist what a stage of 17 feet means in terms of how high the water was on the riverbanks and surrounding land.”

USGS Water School Website

Finding high water marks on or near buildings is easy. You look for the mud line or the edge of debris fields. The same principle applies in nature. Sometimes it’s easy.

Think of high water marks like a bathtub ring around a flooded area. Shown here: East End Park after Imelda.

But they’re not always that obvious.

Can You Spot High Water Marks In Pictures Below?

Below are two pictures used by USGS for demonstration purposes. They took the pictures a few days after a record storm. High-water marks show in both pictures, although a hydrologist would only regard one of the marks as being reliable.

The pictures below are close-ups of the high-water indicators in the top pictures. Did you spot them?

Pictures showing high water marks on vegetation.

The left picture shows a poison ivy vine with the bottom leaves covered in dried mud. Where the mud stops shows how high the floodwaters reached.

The right-side picture shows a limb that hangs over the same creek. During a flood, rapidly-moving water carries leaves and pine needles, etc.! They stick on limbs that are partially submerged. When the stream recedes the signs remain. The top of the leaves and pine straw indicate how high the creek was during the storm.

The mud on the vine is a much better high-water mark than the tree limb, though. During high water, the fast-moving water will cause partially submerged limbs to move up and down. Therefore, hydrologists would not use the limb to estimate high water.

How High Water Marks Are Used

Planning Development

Documenting high water marks helps plan development near floodplains. If you know that water reaches a certain mark on the bank every few years, you certainly don’t want people building homes and businesses there.

Determining Extent and Severity of Flooding

Gages can determine the height of a flood. But high water marks can also show the width and extent relative to topography.

After most major flood events, USGS partners with FEMA and other state and federal agencies to flag and survey high water marks in areas that flooded. USGS did so here after Harvey to determine the extent and severity of the flooding.

Prediction of Future Floods

Forecasters can use the data associated with high-water marks to predict the severity of future floods, delineate flood zones, and update current maps that may account for changes in upstream conditions.

Flood Frequency Calculations

High-water mark data is also part of the flood-frequency (or recurrence interval) calculations that FEMA uses to identify areas that are likely to experience a 1 percent chance of happening in any given year. These floods, known as 100-year floods, serve as the foundation for flood management planning.

Inundation Mapping

Another significant use: Flood-Inundation Mapping. A flood-inundation map shows the extent and depth of flooding that occurred in various communities as a result of a major storm or flood event. Inundation maps help determine things like:

  • Changes needed in building codes
  • Evacuation routes
  • Heights of bridges and roads.

Once inundation maps are complete, USGS documents them and makes them publicly available online.

Recreating Data from Damaged Gages

If a flood knocks out a gage, as it did with the one at US59 bridge and the Kingwood Country Club on the San Jacinto West Fork, high-water marks can provide maximum height of a flood after the fact. If the cross section of the river is known (or surveyed), hydrologists can even back-calculate the flow rate.
