Water Quality projects mitigate the various pollutants generated by urbanized areas that are negatively impacting the receiving water bodies and their designated beneficial uses. The Water Quality program establishes the means to plan, design, and construct specific water quality projects within priority basins in order to treat stormwater runoff and meet the current TMDL for E.coli that exists on the South Platte River and future regulations for nutrients. Water quality facilities, also known as green infrastructure, provide other citywide benefits including increased open space, heat island mitigation, improved air quality, enhanced community livability and linkages for connectivity in urban corridors.
Green Infrastructure (GI) opportunities can occur on several different scales and have been identified from large (regional) and sub-regional through smaller site-scale practices. On a regional scale, green infrastructure refers to a network of parks, open spaces, drainageways, and floodplains which help mitigate the impacts of impervious surfaces and urbanization. Site scale smaller controls, such as green streets, include smaller controls that are often well suited for urban settings. Regardless of scale, green infrastructure design mimics nature and uses vegetation, soils and roots to soil, filter and treat stormwater runoff.
