can a classic campus green and urban social space perform as hard-working, green infrastructure?

SHOEMAKER GREEN @ THE UNIVERSITY OF PENNSYLVANIA

Shoemaker Green unfurls like a green carpet, welcoming you into the University of Pennsylvania’s iconic athletic precinct. The central, semicircular lawn and large rain garden are bordered by precisely-detailed stone retaining walls and elegantly-graded pathways. The design draws on the character of the classic college green while integrating adjacent building entrances, pathways, curbs, and steps across a steeply sloping site. But that deceptively simple campus green is also an urban work-horse. It manages an impressive amount of stormwater, supports native plant and animal habitats, and accommodates gatherings large and small, while seamlessly providing universal access throughout the park. We know that Shoemaker Green works because of an interdisciplinary, 3-year, post-occupancy research and monitoring project.

The design of Shoemaker Green stems from a systems-based thinking that integrates natural systems (soils, plants, insects, birds and human beings) with man-made systems (building components and infrastructure) to function as a whole. The design has a two-pronged approach to manage the site’s stormwater. The first strategy is to convey stormwater runoff to a large, two-tiered rain garden that contains designed soils and native plant species to manage, filter, store, and transpire a significant amount of stormwater. A second approach is to collect stormwater runoff from the site, as well as runoff from the roof and condensate from adjacent buildings, and release the water into the soil under the main green. This water is cleaned while percolating through the designed soils as it makes its way to a large storage bed several feet below the green. A large portion of the existing tennis courts were left in-place under the main green to support a recycled aggregate storage bed. Any excess water that is not taken up by the soils and plants is captured in this bed through an underdrainage system and conveyed to a large cistern and stored for reuse. Once the entire system reaches full capacity, very large storms overflow to the existing municipal sewer line preventing flooding.
