11 8TH 9TH 6TH 7TH 3RD 6TH 7TH You Will See Ecoroofs An ecoroof is a lightweight, low maintenance vegetated roof that soaks up rain and reduces stormwater runoff. Ecoroofs also reduce the heat island effect that warms the air over cities, and naturally insulate buildings to reduce energy use. Naturescaping Naturescaping is landscaping with native plants that require less water and little or no fertilizers or pesticides. Planters, Swales, and Rain gardens Planters, swales, and rain gardens are landscaped areas that collect stormwater and filter it as it flows through plants and soil. There are many ways to direct stormwater to these facilities, including curb cuts in parking lots and open grates. Green Streets A Green Street is a natural stormwater management approach that uses plants and soil to slow, filter, and cleanse stormwater from streets. Green Streets convert stormwater from a waste directed into a pipe, into a resource that replenishes groundwater supplies. Other Technologies Porous paving, rainwater harvesting, innovative conveyance, art pieces, and disconnected downspouts are examples of other sustainable stormwater management technologies.
