Installing concrete sidewalks and parking areas will increase the quantity of the rainwater that is discharged from a site. Rainwater is the water that falls as precipitation on a site. Rainwater discharge is the amount of rainwater that leaves a site as surface runoff or subsurface flow. Rainwater discharge can affect the quantity and quality of water resources downstream by causing erosion, flooding, sedimentation, pollution, and habitat loss. Concrete sidewalks and parking areas are examples ofimpervious surfaces that prevent rainwater from infiltrating intothe soil and increase rainwater discharge by creating more runoff1 . References: LEED v4 Green Associate Candidate Handbook1, EPA’s Stormwater Management
