2016 Annual Report • Public Works Department • St. Anthony Village, Minnesota <br /> <br /> <br /> <br />9 <br /> <br />Central Park Bio-Swale <br />The Central Park Stormwater Biofiltration System is located on the north end of Central Park in <br />the existing depression near the hockey rink and south of the homes on Skycroft Drive. The <br />system uses a sand and compost filtration bed where stormwater enters the pond, filters <br />through the sand and compost filter, and then a series of pipes underneath the pond collect that <br />water and drain it downstream. The project’s purpose is to remove phosphorus and total <br />suspended sediments that come into the pond from the adjacent park, school and parking lot <br />areas. The system was completed in the spring of 2015 and fully operational in 2016. The <br />pollinator species planted in the swale have successfully taken root and are part of the <br />pollinator pathway. <br />The City aims to reduce stormwater pollutants conveyed downstream into Rice Creek County <br />Ditch System 3, which is tributary to Long Lake in the City of New Brighton. <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br />
