Improvements in dealing with storm water can be seen in a variety of decentralized Low Impact Development (LID) projects, like those visible at the south east edge of the Comcast parking lots, which catch and filter contaminated runoff from these paved surfaces before the runoff reaches Campus Creek. Other areas on campus that serve to filter or catch storm water include a large retrofit bioretention pond behind the Clarice Smith Performing Arts Center and a sand filter on the south lawn of the University House. Also, the women's field hockey field filters, slows, and reduces the temperature of storm water runoff before it reaches the Paint Branch. Campus Creek, which is a high priority for restoration, includes four LID projects within the stream buffer of the creek. At the eastern border of Lot 4i, the university partnered with the Maryland State Highway Administration to install a bioretention facility that treats uncontrolled runoff from the parking area before it reaches the Paint Branch. Throughout the campus new plantings and expansion of the riparian buffer are planned.
