Guthrie Green Bioswales

BY Ryan Howell, Guthrie Green Staff

Rock-lined bioswales are designed into the landscape elements of Guthrie Green. These “drainages” located on both the east and west sides of the Green are specifically designed to remove silt and small trash from surface runoff water. They consist of a swaled drainage course with gently sloped sides and planted with a variety of native vegetation. As water runs down the bioswales, the plants and rocks slow the flow of water and allowing silt and pollutants like trash to settle in place instead of running into the city sewer systems.
