Green Infrastructure

Around the world, cities are adopting green infrastructure to help store, absorb and filter precipitation. Green infrastructure can be implemented on a small site scale, neighborhood scale or community-wide scale and performs two important functions — protecting water quality and reducing the quantity of stormwater runoff. 

This website provides tools and resources related to policy, planning and mapping, financing and maintenance to help you explore how green infrastructure could be incorporated into your community.
