Green Stormwater Infrastructure
Green stormwater infrastructure (GSI) employs natural elements to manage and treat stormwater, enhance water quality, and provide environmental and community benefits. By integrating vegetation, soils, and natural systems, GSI reduces runoff, filters pollutants, and mitigates flooding. Common GSI practices include rain gardens, permeable pavements, green roofs, bioswales, urban forests and trees, low impact development, and stream and wetland restoration. These approaches not only manage stormwater effectively, but also improve air quality, reduce urban heat islands, and create green spaces for community recreation.
