Green infrastructure is a cost-effective, resilient way to manage our stormwater that provides lots of community benefits. This practice reduces and treats stormwater at its source while provided environmental, social, and economic benefits. Stormwater runoff is a major contributor of water pollution in urban areas. When precipitation falls onto our streets, roofs, and parking lots, it does not immediately soak into the ground. As it travels to our infrastructure system, it collects trash, bacteria and other pollutants. Also, higher amounts of urban water flow can cause erosion and flooding in our streams, damaging natural habitats, property and infrastructure. When precipitation falls in undeveloped areas, it is absorbed into the ground and filtered by plants and soil. The stormwater runoff is cleaner and less of an issue.
Green infrastructure uses plants, soils and other elements and practices to restore some of the natural processes to manage stormwater. This can create healthier urban environments. Green infrastructure on a larger scale can create areas that provide habitats, flood protection, cleaner air and water. On a smaller scale, it can create stormwater management systems that replicate nature by soaking up and storing water.
