These Houston entrepreneurs and startups are searching for flooding solutions

Flood tech

The feeling is all too familiar for Houstonians. Tropical Storm Imelda hit Houston with devastating flood waters just two years after Hurricane Harvey did its damage.

With any obstacle or challenge, there is room for innovation. Over the past year, InnovationMap has covered various flood tech startups in Houston. Here are six innovations that can make a difference the next time a storm decides to take its toll on Houston.

Self-deploying flood protection for buildings

A self-deploying flood damage prevention device caught Tasha Nielsen's eye on a trip to Denmark, and then launched the U.S. iteration of FloodFrame to bring the technology here.

FloodFrame works by using buoyancy. A lightweight cloth is wrapped around a tube is installed underground outside the perimeter of your home or business. One end of that cloth is attached to a box that is also installed underground. As flooding begins, an automatic system will release the lids to deploy the inflation of the tube that will protect the structure. When the flood comes in, the system will float on top of the flood — kind of like a pool noodle — and protect the structure from the water.

FloodFrame adds a level of security during flooding events and can be considered more cost-effective when compared to the high cost of renovating or rebuilding after flooding.

"Right now we are focused on residential but I think there's a huge potential for it to go commercial. A lot of commercial buildings are self insured, and commercial developers, industrial developers, this would be a drop in the bucket for the overall cost of the entire project," Nielsen tells InnovationMap. "For homeowners, it's kind of a bigger expense, but I think there is the potential for homebuilders to include it as an option in the entire package of a new house because when you put it in to a mortgage, it's only another like $0.50 a month."

Floodwaters from Hurricane Harvey seriously damaged about 600,000 vehicles in the Houston area, which included Rahel Abraham's 2008 Infiniti G35. Now, Abraham's brainchild forms the backbone of her Houston-based startup, ClimaGuard LLC. The company's waterproof, temperature-resistant, portable Temporary Protective Enclosure (TPE) can entirely cover a compact car, sedan, or midsize SUV. It comes in three sizes; the cost ranges from $349 to $499.

To protect a vehicle, someone sets a TPE on the ground, a driveway, or another flat surface, then drives the vehicle onto the bottom part of the product, and connects the bottom and top parts with the zipper. Abraham likens it to a clamshell preserving a pearl.

"My goal is not to make it to where it's an exclusive product — available only to those who can afford it — but I want to be able to help those who it would make even more of an economic impact for," Abraham tells InnovationMap.

It only took a natural disaster for Reda Hicks to make her startup idea into a reality.

"I had been thinking on what it would be like to help people find space to do business in and how businesses find a way to stay in business a long time," Hicks tells InnovationMap. "But, I was afraid of the tech."

Hicks, who has practiced law for almost 15 years, wanted to create a website that allows for people with commercial space — a commercial kitchen, conference room, spare desks, etc. — to list it. Then, space seekers — entrepreneurs, nonprofits, freelancers, etc. — can rent it. When Hurricane Harvey hit, Hicks was kicking herself for not acting on her idea sooner.

"It was really Harvey and having so many people desperate to find space for emergency purposes that made me realize there are so many contexts in which people need space right away for something specific," she says. "Certainly the primary user is the entrepreneur trying to grow their business, but there are so many other reasons why a community would need better access to the space it already has."

Now Hicks is growing GotSpot in hopes that short-term rental space and emergency housing can be smooth sailing no matter the circumstances. Recently, the company was named a finalist for MassChallenge Texas in Austin.

In the wake of Hurricane Harvey, many Houstonians began to think of solutions for the next time Mother Nature struck with her full-force of flooding. Gensler designers Chelsea Bryant, Jordan Gomez, Luisa Melendez, Barbara Novoa, Benjamin Nanson, Maria Qi, and Melinda Ubera created a solution as a part of Gensler's By Design program called Fil Trat. The tower can absorb, filter, and store flood waters until the bayou is ready for the water to be released — cleaner than it was before.

During Harvey, thousands of people were displaced, but Fil Trat has a solution for that too. The tower's floors would alternate between filtration floors and shelters, which could house up to 24 families per floor.

While the suggested Houston locale would be by Buffalo Bayou, the group suggests putting the tower in other coastal cities at risk of devastating flooding.

Nearly two years after Hurricane Harvey battered the Houston area, a flock of electronic "rubber ducks" flew above homes in Katy in a broader endeavor to keep first responders and victims connected during natural disasters.

Developers and backers of Project Owl, an Internet of Things (IoT) hardware and software combination, conducted a pilot test of this innovation June 1 — the first day of this year's hurricane season. In the Katy test, 36 "ducks" took flight.

"So, our technology can be deployed to help communities that have been destroyed after natural disasters by providing quickly accessible communications network to coordinate and organize a response," Bryan Knouse, co-founder and CEO of Project Owl, tells InnovationMap.

The DuckLink network comprises hubs resembling rubber ducks, which can float in flooded areas if needed. It takes only five of these hubs to cover one square mile. This network sends speech-based communications using conversational systems (like Alexa and Facebook Messenger) to a central application. The app, the Owl software incident management system, relies on predictive analytics and various data sources to build a dashboard for first responders.

Before it was the fourth largest city in America, Houston was a prairie. That type of ecosystem — thick with prairie grass — is very absorbing when it comes to rain water. Cassidy Brown Johnson, a Rice University lecturer and president of the Coastal Prairie Partnership, has been taking every opportunity to raise awareness on the importance of prairie restoration.

"It's really surprising to people that the trees and all this lushness is actually all artificial," Johnson says. "We know that this ecosystem evolved with the cyclical flooding events that happened here."

This movement to bring back Houston's ancient ecosystem is a new focus on a few prairie conservationist groups — and even the Harris County Flood Control. This has been going on for a while, but recent flooding events have opened the eyes of people now looking for reliable solutions to flooding problems.

"After Hurricane Harvey, people started realizing that this might be one of the solutions we could actually investigate and see if it can help us," Johnson says. "A green space is going to absorb way more water than a parking lot."

Memorial Park Conservancy's master plan redevelopment project, which is being supported by the Kinder Foundation, includes a lot of prairie restoration plans is expected to deliver by 2028.

The project is a collaborative effort between MPC, Uptown Houston TIRZ, and Houston Parks, Kinder Foundation, and Recreation Department to redevelop the 1,500-acre park. An ongoing part of the transformation will be stormwater management upgrades. MPC has budgeted $3 million to this asset of the renovation. While a part of the plan is tributaries for run-off water, bringing back prairie and wetlands will do a great deal to help abate stormwater.

"We're taking ball fields, parking lots, and roads and converting them back to what was here — native wetland coastal prairie," MPC president and CEO Shellye Arnold tells InnovationMap. "This serves important stormwater purposes."

2 Houston space tech cos. celebrate major tech milestones

big wins

Two Houston aerospace companies — Intuitive Machines and Venus Aerospace — have reached testing milestones for equipment they’re developing.

Intuitive Machines recently completed the first round of “human in the loop” testing for its Moon RACER (Reusable Autonomous Crewed Exploration Rover) lunar terrain vehicle. The company conducted the test at NASA’s Johnson Space Center.

RACER is one of three lunar terrain vehicles being considered by NASA for the space agency’s Artemis initiative, which will send astronauts to the moon.

NASA says human-in-the-loop testing can reveal design flaws and technical problems, and can lead to cost-efficient improvements. In addition, it can elevate the design process from 2D to 3D modeling.

Intuitive Machines says the testing “proved invaluable.” NASA astronauts served as test subjects who provided feedback about the Moon RACER’s functionality.

The Moon RACER, featuring a rechargeable electric battery and a robotic arm, will be able to accommodate two astronauts and more than 880 pounds of cargo. It’s being designed to pull a trailer loaded with more than 1,760 pounds of cargo.

Another Houston company, Venus Aerospace, recently achieved ignition of its VDR2 rocket engine. The engine, being developed in tandem with Ohio-based Velontra — which aims to produce hypersonic planes — combines the functions of a rotating detonation rocket engine with those of a ramjet.

A rotating detonation rocket engine, which isn’t equipped with moving parts, rapidly burns fuel via a supersonic detonation wave, according to the Air Force Research Laboratory. In turn, the engine delivers high performance in a small volume, the lab says. This savings in volume can offer range, speed, and affordability benefits compared with ramjets, rockets, and gas turbines.

A ramjet is a type of “air breathing” jet engine that does not include a rotary engine, according to the SKYbrary electronic database. Instead, it uses the forward motion of the engine to compress incoming air.

A ramjet can’t function at zero airspeed, so it can’t power an aircraft during all phases of flight, according to SKYbrary. Therefore, it must be paired with another kind of propulsion, such as a rotating detonation rocket engine, to enable acceleration at a speed where the ramjet can produce thrust.

“With this successful test and ignition, Venus Aerospace has demonstrated the exceptional ability to start a [ramjet] at takeoff speed, which is revolutionary,” the company says.

Venus Aerospace plans further testing of its engine in 2025.

METRO rolls out electric shuttles for downtown Houston commuters

on a roll

The innovative METRO microtransit program will be expanding to the downtown area, the Metropolitan Transit Authority of Harris County announced on Monday.

“Microtransit is a proven solution to get more people where they need to go safely and efficiently,” Houston Mayor John Whitmire said in a statement. “Connected communities are safer communities, and bringing microtransit to Houston builds on my promise for smart, fiscally-sound infrastructure growth.”

The program started in June 2023 when the city’s nonprofit Evolve Houston partnered with the for-profit Ryde company to offer free shuttle service to residents of Second and Third Ward. The shuttles are all-electric and take riders to bus stops, medical buildings, and grocery stores. Essentially, it works as a traditional ride-share service but focuses on multiple passengers in areas where bus access may involve hazards or other obstacles. Riders access the system through the Ride Circuit app.

So far, the microtransit system has made a positive impact in the wards according to METRO. This has led to the current expansion into the downtown area. The system is not designed to replace the standard bus service, but to help riders navigate to it through areas where bus service is more difficult.

“Integrating microtransit into METRO’s public transit system demonstrates a commitment to finding innovative solutions that meet our customers where they are,” said METRO Board Chair Elizabeth Gonzalez Brock. “This on-demand service provides a flexible, easier way to reach METRO buses and rail lines and will grow ridership by solving the first- and last-mile challenges that have hindered people’s ability to choose METRO.”

The City of Houston approved a renewal of the microtransit program in July, authorizing Evolve Houston to spend $1.3 million on it. Some, like council member Letitia Plummer, have questioned whether microtransit is really the future for METRO as the service cuts lines such as the University Corridor.

However, the microtransit system serves clear and longstanding needs in Houston. Getting to and from bus stops in the city with its long blocks, spread-out communities, and fickle pedestrian ways can be difficult, especially for poor or disabled riders. While the bus and rail work fine for longer distances, shorter ones can be underserved.

Even in places like downtown where stops are plentiful, movement between them can still involve walks of a mile or more, and may not serve for short trips.

“Our microtransit service is a game-changer for connecting people, and we are thrilled to launch it in downtown Houston,” said Evolve executive director Casey Brown. “The all-electric, on-demand service complements METRO’s existing fixed-route systems while offering a new solution for short trips. This launch marks an important milestone for our service, and we look forward to introducing additional zones in the new year — improving access to public transit and local destinations.”
