Which of the following best describes the institution’s approach to rainwater management?:
Less comprehensive policies, plans or guidelines that incorporate green infrastructure

A brief description of the institution’s green infrastructure and LID practices:

The Penn "Stormwater Management Plan" describes guidelines for managing existing infrastructure along with a catalog of potential new projects and revised details for best management practices in stormwater management. Penn has implemented many elements of green infrastructure, including over 20 green roofs, bioswales, meadow grass lawns, gardens and lawns where rainwater is allowed to infiltrate into the soil, detention basins, underground cisterns, and permeable paving. The landscape standard for sidewalks adjacent to Penn properties, for example, includes a linear tree pit set with loose-laid cobbles in a sand bed.

Shoemaker Green, a public commons, combines welcoming open spaces of lawns, tree-lined walkways, and sitting areas with robust stormwater management techniques. This green space is both a destination and a heavily-trafficked pedestrian route in the athletics precinct of campus, two blocks from College Green. Shoemaker Green's sustainable site management improves water quality and minimize runoff, reduces the effect of the urban heat island by greening large paved areas, restores biomass on site, increases local biodiversity, and improves the overall environment for the community.

The 24-acre Penn Park, completed in 2011 and built on the site of a former brownfield, increased the green/open space on campus by 20 percent. One of the appealing features of Penn Park is the return of vegetation and plant life to an area that was paved in asphalt and an industrial site for decades. Specific native and adaptive plants are used throughout the site to reduce irrigation requirements. Of the 548 trees planted in Penn Park at its completion, species included: catalpa, hackberry, swamp white oak, white pine, metasequoia, larch and balsam pine. These species were selected with specific attention to where they appear relative to their position on the land, with trees that prefer wet soil conditions planted in the lower levels, and hedgerow trees, which are more drought resistant, planted along the top of the landforms. A cistern was installed as part of Penn Park thar can hold up to 300,000 gallons of rainwater that is used for irrigation. In 2015, an orchard was planted at the south end of Penn Park, as well as a strawberry patch. Each year, new species are added in the orchard, which now includes apples, pears, pawpaws, peaches, almond, and other fruit bearing trees.

In addition to Shoemaker Green and Penn Park, many new construction buildings on campus feature green roofs and cisterns for stormwater management. Of note is New College House which was completed in 2016 and features nine green roofs with 95 percent water retention abilities. The large sloping lawn of the dormitory features a below grade cistern for stormwater management and irrigation and also provides a tenth green roof and open lawn for the campus.

The University of Pennsylvania is a major research institution, with over 3,000 degrees granted annually from twelve professional and academic schools at the Bachelor's, Master's, and Doctorate levels. Penn is committed to reducing emissions and energy use, as stated in the 2014 "Climate Action Plan 2.0". This submission documents Penn's efforts during the FY17 year and compares them to the FY14 baseline year which corresponds with the University's "Climate Action Plan. 2.0". The submission relies on information related to the main, academic, West Philadelphia campus, but to more fully document efforts across the Penn system, information related to the Morris Arboretum and New Bolton has also been referenced and noted as outside the boundary in descriptions. The information is used to enrich examples of University efforts and is not intended to be the primary justification for credits. The responses for each of the questions and sub-questions are drawn from University materials, both internal and public documents. Each section notes the website where the information can be found.
