Green infrastructure (GI) is a term that has evolved, originally referring to a strategic landscape approach to using open space for environmental, social, and economic benefits. GI now more often refers specifically to an approach for managing Stormwater runoff that relies on using natural processes in the soil and vegetation to infiltrate, evapotranspirate and/or harvest Stormwater runoff. Rain gardens, bioswales, and pervious paving are all examples of green infrastructure.
