Does the institution have a policy, plan, and/or strategies to reduce stormwater runoff from new development projects? :
Does the institution have a policy, plan, and/or strategies to reduce stormwater runoff from ongoing campus operations? :
A brief description of the institution's stormwater management initiatives:
Green roof designs have been incorporated on two campus buildings, Cumberland Hall and the Adele Stamp Student Union within the last several years. These vegetated roof systems exploit the ability of plants to absorb and transpire rainwater, slowing or eliminating storm water runoff, and to insulate structures from extremes of heat and cold, reducing heating and cooling costs and possibly extending the life of roofing structures as well as reducing heat island effects.
Rain Gardens are used in and near parking lots to slow, cool and filter storm water before it reaches tributaries of the Chesapeake Bay. Cisterns, which capture rainwater for use as needed to irrigate landscape plants, have been incorporated in several areas, including Washington Quad and Knight Hall, further reduce the movement of excess storm water off campus.

Does the institution have a living or vegetated roof?:
A brief description of the institution's living or vegetated roof:
The Department of Residential Facilities installed a green roof system on Cumberland Hall in 2008. The green roof covers approximately 65 percent roof surface with approximately 6,000 square feet of plantings. The Cumberland Hall roof is characterized as an "extensive" green roof meaning the depth of the growing media is between 3" - 6" and the plants are low growing, low maintenance, and drought resistant. Extensive green roof systems are not designed to accommodate foot traffic.
There is also a partial green roof installed at the Stamp Student Union. The original roof installation in 2009 failed in essence by disintegrating to ‘fine’ and preventing the plants from flourishing. In conjunction with the Department of Plant Science & Landscape Architecture, Stamp brought in The Furbish Company, an industry leader in green roof installations to work on the re-installation of the green roofs during the spring of 2013. Once the new vegetated roofs are in place, Stamp has entered in to a stewardship program with Plant Science faculty to use the new system as ‘learning research labs’ for their students and which will also help to insure long term success!
Green roofing systems have also been employed on the Landscape Services Heavy Equipment Building, the Transportation Services Shuttle Facility, and the Physical Sciences Complex.
Does the institution have porous paving?:
A brief description of the institution's porous paving:
Maryland installed permeable pavement at Symons Hall, an academic building used by the College of Agriculture & Natural Resources. Variations of porous paving are being used at the service drive for the Clarice Smith Performing Arts Center, and the Labyrinth and the Memorial Chapel. Gravelpave has been installed on the Denton Quad.
Does the institution have retention ponds?:
A brief description of the institution's retention ponds:
Maryland has bioretention ponds behind the Clarice Smith Performing Arts Center, Comcast Center, the Animal Science Building, and the Chesapeake Building, as well as at other locations on campus.
Does the institution have stone swales?:
A brief description of the institution's stone swales:
Stone swales are used in Lot 1c for pretreatment purposes for a vegetated bioretention facility.
Does the institution have vegetated swales?:
A brief description of the institution's vegetated swales:
Lot FF by Comcast Center and the University House utilize vegetated swales.
Does the institution employ any other technologies or strategies for stormwater management?:
A brief description of other technologies or strategies for stormwater management employed:
A variety of decentralized Low Impact Development (LID) projects are used around campus to help absorb stormwater before it enters local creeks. Read more at http://www.sustainability.umd.edu/content/campus/stormwater.php#LID
