Mahoney Creek Tributary Detention Basin

Our team was hired for the establishment and improvement of two stormwater detention basins along the Mahoney Creek Tributary. A key goal of this project was to ensure successful establishment of native prairie vegetation for both basins. Our restoration work included native seeding, installing erosion control blanket, native plugs and trees, as well as a turf berm and traditional landscape trees. Additional improvements included installing a new storm sewer, removing an existing sanitary sewer, and installing new sanitary at a lower elevation. To ensure the long-term success of this native restoration, we are performing three years of site monitoring and ecological maintenance.
