City of Houston launches pilot program to promote stormwater infrastructure growth

The City of Houston has launched a pilot project that will speed up the permitting process for environmentally friendly stormwater projects.

The Green Stormwater Infrastructure Expedited Permitting Pilot Program, announced August 4, will approve at least 10 projects in the Houston area by August 2022. In conjunction with the Resilient Houston initiative, the city is targeting 100 green stormwater infrastructure projects by 2025.

The city is working on rules and regulations that will govern development of green stormwater infrastructure. Mayor Sylvester Turner rolled out a tax abatement program for green stormwater infrastructure projects last December.

According to a city news release, green stormwater infrastructure improves the performance of drainage systems and can make real estate projects more attractive to buyers, while delivering benefits such as heat reduction, improvement of air and water quality, and conservation of native habitats.

Green stormwater infrastructure helps reduce the downstream impact of development and mimics how rain behaves when it falls onto an undeveloped green landscape. Techniques that fit into this category include green roofs, rain gardens, rainwater harvesting, permeable pavement, and urban forests.

"In the aftermath of Hurricane Harvey, we have taken critical steps to address our flooding and drainage challenges. As Houston has rapidly developed, we have relied on traditional gray infrastructure systems to keep us safe. However, as we build forward, we must consider new and innovative approaches for achieving greater flood resilience in Houston," the city says in a 2019 report about green stormwater infrastructure.

Traditional "gray" infrastructure, designed to move urban stormwater away from the built environment, includes curbs, gutters, drains, piping, and collection systems, according to the U.S. Environmental Protection Agency (EPA). Generally, gray infrastructure collects and moves stormwater from impervious surfaces, such as roadways, parking lots, and rooftops, and into a series of pipes that ultimately send untreated stormwater into local waterways.

In tandem with Houston's new permitting program, the city has created the Green Stormwater Infrastructure Awards and Recognition Program. The program salutes green development and redevelopment projects. It "is intended to recognize some of the most effective and exemplary of 'green' building in Houston and encourage more development projects to adopt resilient measures," according to the news release.

Projects considered for the awards program will be judged on factors such as:

  • Proximity to nearby communities.
  • Impact on nearby communities.
  • Efforts to conserve native plants.

Turner says the permitting and awards programs are part of an initiative aimed at "futureproofing our city" to ease harm caused by hurricanes and flooding.

"In Houston and in towns across the U.S., climate change is no longer knocking on our front door; it's broken into the house," Turner wrote in an opinion piece published in July by The Hill.

Building Houston

University of Houston researchers and students are bringing multiple realities together to help improve the design process for crewed space missions.

Helmed by Vittorio Netti, a researcher for UH and a space architect, the university has launched an XR Lab within the University of Houston architecture building. The lab allows researchers to combine mixed reality (MR), virtual reality (VR), augmented reality (AR) and extended reality (XR) to "blend the physical and digital worlds" to give designers a better understanding of life in space, according to a release from UH.

In the lab researchers can wear MY space suits and goggles, take a VR space walk, or feel what it's like to float to the International Space Station with the help of XR and a crane.

The area in which the researchers conduct this work is known as the "cage" and was developed during a six-month research and design study of lunar surface architecture sponsored by Boeing, which aimed to learn more about the design of a lunar terrain vehicle and a small lunar habitat.

The work is part of UH's Sasakawa International Center of Space Architecture (SICSA), which is led by Olga Bannova, a research associate professor and director of the space architecture graduate program at UH.

She says work like this will drastically cut down research and development time when designing space structures.

“These technologies should be harnessed to mitigate the dependency on physical prototyping of assets and help optimize the design process, drastically reducing research-and-development time and providing a higher level of immersion,” Bannova said in a statement.

Today the research team is shifting its focus on designing for a Mars landing. In the future, they aim to demonstrate and test the system for habitats designed for both lunar and Martian surfaces. They are also working with Boeing to test designs in microgravity, or zero gravity, which exists inside the International Space Station.
