A brief description of the institution’s green infrastructure and LID practices:
Swarthmore College follows a rigid Environmental Sustainability Framework for new construction and major renovation projects, informed by an in-depth analysis of key opportunities for energy conservation and renewable energy and the most effective areas on campus to manage stormwater. As the host of the Scott Arboretum, the College has a great interest in storm water control. The campus boasts 7 green roofs, more than 10 underground stormwater infiltration structures, use of porous asphalt, 2 bioretention ponds and numerous infiltration beds (rain gardens).
The newly completed Singer Hall included a heavy emphasis on rainwater management with features including rainwater harvesting, storage, and usage, which reduces potable water consumption by using rainwater for water flushing of water closets.

A brief description of the institution’s rainwater management policy, plan, and/or guidelines that supports the responses above:
The campus includes one of the last vestiges of natural woodlands in Delaware County, PA bisected by the Crum Creek where virtually all surface run-off accumulates. Slowing the rate of discharge not only limits erosion but aids in limiting flooding downstream of the campus. The college has it's own Crum Woods Committee and is also active with the Chester-Ridley-Crum Watersheds Association. Website: https://www.crcwatersheds.org/
The college has constructed bioswales, green roofs, porous pavement, and in general limited the amount of paved areas to control stormwater runoff.
