Assessing Green Infrastructure Performance and Cost

November 2016

Green infrastructure (GI) systems are installed in strategic locations to capture stormwater runoff after a rain event. GI projects are placed in locations to slow stormwater flows to streams, reduce flooding or fast currents that erode stream banks, or filter pollutants from parking lots or roadways. This fact sheet highlights how GI projects such as rain gardens, permeable pavement, and tree filters are part of a stormwater runoff toolkit for local decision-makers.
