Green Stormwater Infrastructure (GSI) uses natural processes like rain gardens and cisterns to slow, capture, and clean polluted runoff before it harms our lakes, rivers, and streams. It also helps add color and beauty to our homes and communities
In 2013, Seattle set a target to manage 700 million gallons of polluted runoff per year with green stormwater infrastructure (GSI) by 2025. This is being addressed through City Council led projects. inclusion of guidance within the Seattle Stormwater Code, and a community focused media campaign. More information can be found here.
