Traditional “grey” infrastructure (e.g., stormwater pipes, sewage systems) is expensive to install, maintain, and upgrade. Green infrastructure provides cost-effective solutions by reducing the need for new pipes, wastewater plants, and other expensive infrastructure. Additionally, it enhances property values, attracts investments, and can be eligible for government grants and rebates. Green infrastructure Design uses vegetation, soils, and other elements and practices to restore some of the natural processes required to manage water and create healthier urban environments. At the city or county scale, green infrastructure is a patchwork of natural areas that provides habitat, flood protection, cleaner air, and cleaner water. At the neighborhood or site scale, stormwater management systems that mimic nature soak up and store water.While gray stormwater infrastructure is designed to move urban stormwater, green infrastructure design reduces and treats stormwater at its source while delivering environmental, social, and economic benefits. Stormwater runoff is a major cause of pollution in urban areas. When rain falls on our roofs, streets, and parking lots the water cannot soak into the ground as it should.
