This raingarden was implemented in December of 2016 and retrofitted into an existing sod-lined detention basin. Elevating the drain levels above the basin floor allows for infiltration of water and treatment of the 'first flush' off of pavement, instead of immediate discharge into the storm sewer. The drains become secondary measures to capture overflow, preventing flooding. Colorful, seasonal native plants that host and abundance of wildlife, such as birds and pollinators, are beautiful and useful for environmental education. Erosion-prevention techniques, such as rock check dams and native grasses with dense root systems were also employed.
