What is Green Infrastructure?

Green Infrastructure is an overarching term used to capture the wide range of natural assets and strategies used in the built environment to improve the quality of our natural resources and contribute to healthier natural habitat, increased recreational opportunities, and improved aesthetics. Working at several scales (municipal, neighborhood, and site), it is the strategic integration of nature into urban environments to enhance environmental values.

Green Infrastructure Woordle By weaving natural processes into the built environment, green infrastructure provides a range of benefits including:
  • stormwater management
  • flood mitigation
  • air quality improvements
  • mitigation of urban heat island effect
  • reduced water and energy use
  • habitat enhancement
  • facilitate walking and biking
  • increased recreational opportunities
  • improved aesthetics

Green Stormwater Infrastructure

Specifically with respect to stormwater management, green infrastructure can provide source control of stormwater, limit its transport and pollutant conveyance to the collection system, restore predevelopment hydrology to the extent possible, and provide environmentally enhanced systems. American Rivers, describes it as follows:

"On the local level, green infrastructure practices include rain gardens, permeable pavements, green roofs, infiltration planters, trees and tree boxes, and rainwater harvesting systems. At the largest scale, the preservation and restoration of natural landscapes (such as forests, floodplains and wetlands) are critical components of green infrastructure."
