Chicago's Navy Pier showcases an impressive green infrastructure designed for efficient stormwater management. Featuring seventy-seven tree tubs and permeable pavement, the system effectively captures and filters rainwater runoff, preventing pollutants from contaminating local waterways year after year. Not only do the trees enhance the shore with shade, but they also significantly improve air quality while managing water. This innovative initiative stands as a prime example of urban water management solutions.
