Green infrastructure is a cost-effective, resilient approach to managing impacts of climate change that can also provide many community benefits. For example, single-purpose gray stormwater infrastructure—conventional piped drainage and water treatment systems—is designed to move urban stormwater away from the built environment. Green infrastructure reduces and treats stormwater at its source while delivering environmental, social, and economic benefits.
Some examples include rain gardens, bioswales, permeable pavement, and green roofs.
