Unlike pipes and treatment plants that collect and clean polluted runoff after it travels for miles, GSI uses plants, trees, soil, and engineering inspired by natural drainage systems to manage stormwater where it falls. By mimicking natural processes, we protect our waterways AND enjoy numerous other benefits. Green Stormwater Infrastructure increases the number of trees and plants in our neighborhoods, provides habitat for pollinators, improves air quality, and naturally replenishes groundwater.
Increasing the reach and effectiveness of GSI through technical innovation is a long-standing practice. Learn more about the history of GSI in Seattle, and what’s next for innovative GSI solutions.
