Green Stormwater Infrastructure (GSI)

Detroiters are using natural solutions to capture and filter excess rainwater to help reduce flooding and untreated combined sewage discharges into our rivers. The Detroit Stormwater Hub provides a place to share Green Stormwater Infrastructure projects, access resources and learn from one another.

Together, we’re committed to making Detroit the greenest city in America!

Projects shared on Detroit Stormwater Hub provide local examples of GSI in action. This helps make all of our stormwater management work more visible, encourages our neighbors to install GSI of their own, and demonstrates the collective impact that residents, businesses, non-profits, and the city can have when we come together.

“As a life-long resident of Detroit, my vision is one of a vibrant and healthy community with nature all around. Green Stormwater Infrastructure’s goal is to keep our rivers clean by reducing sewage overflows, but the practices are also wonderful examples of how to bring us closer to nature. I am grateful for the accomplishments by city government, businesses and organizations. I am most inspired and in awe of the projects and efforts by everyday people who care.”
