How can basketball courts reduce flood risk
A Basketball Court That Becomes Stormwater Infrastructure
A basketball court at NYCHA’s South Jamaica Houses has been designed to do something unusual during a cloudburst: temporarily hold stormwater instead of sending all of it immediately into the sewer system. Most days, it remains a public space for play. During an intense downpour, it becomes part of the neighborhood’s drainage system.
Why the “cloudburst” idea matters Cloudbursts are short, intense rain events that can overwhelm underground pipes even when the total rainfall for the day does not seem extraordinary. In a dense city, there is little exposed soil available to absorb water. Roofs, sidewalks, streets, and paved courtyards move rain quickly toward storm drains, basements, and low points.
The basic adaptation problem is therefore not only about building larger pipes. It is also about slowing the water down, storing it safely for a short period, and giving it more routes into the ground or the drainage network. The South Jamaica project combines green infrastructure with engineered, or “gray,” infrastructure to do that.
A public space with a second job The basketball court is the clearest part of the project because its function is easy to see. Under ordinary conditions, it is a court. During a major storm, it can serve as temporary storage, reducing the speed and volume of runoff moving through the surrounding system.
That dual use is important. Climate adaptation is often presented as a separate category of construction, somewhere behind a fence or buried underground. Here, at least one protective function is integrated into a place residents already use. The design has to work for recreation, accessibility, maintenance, and safety, not just for a model of rainfall.
What this can and cannot solve A project like this will not eliminate basement flooding across Jamaica, and it cannot substitute for maintaining sewers, repairing buildings, improving emergency communication, or addressing broader drainage constraints. The evidence from one completed pilot also cannot tell us everything about performance across different storms.
But it creates a useful local test. City agencies can measure how much water is stored, how quickly the space drains, how the landscaping performs, and whether residents find the design practical. Those observations matter as much as the rendered diagrams that usually accompany infrastructure plans.
The information residents need The next step should be making the project legible to the people who live around it. Clear signs, public performance data, and straightforward explanations of what happens during a storm would help residents understand why a familiar court has a technical role.
NYC’s Department of Environmental Protection describes South Jamaica as its first completed cloudburst stormwater pilot. The project is worth watching not because one basketball court can solve a citywide problem, but because it shows what adaptation looks like when it is attached to an ordinary neighborhood space.
