GREEN Infrastructure 101Read Now
Green Infrastructure is defined in the Water Infrastructure Improvement Act as “the range of measures that use plant or soil systems, permeable pavement or other permeable surfaces or substrates, stormwater harvest and reuse, or landscaping to store, infiltrate, or evapotranspirate stormwater and reduce flows to sewer systems or to surface waters.” Examples of some local green infrastructure include rain barrels or gardens, designating areas as open space, and bioswales. Most stormwater management materials used in development are considered “grey infrastructure” which includes pipes, culverts, tunnels, and more. These engineered systems regulate our watershed drainage and will likely never be phased out; however, many developers are now supplementing the grey with the green for a variety of reasons.
The naming convention alone promotes sustainability—these practices have significantly lower carbon footprints just by the reduction in the amount of material that must be mined/extracted, used in production, and transported to the site where they will be installed. Along with requiring less energy and resources to route stormwater runoff, these practices have aesthetic value and economic benefits. Communities have been able to save money by reducing the diameters of piping by directing flow through a rain garden or an open space to allow for infiltration. A lower flow rate can also lead to less transport of pollutants from urban stormwater runoff and the ability to manage higher volumes during flood events.
