The rooftop garden, on the top of an eight-story section of the building at 2013 Market Street, holds growing media of up to eight inches thick, and the vegetative covering reduces rainwater runoff by up to 70%, and also insulates the building.
Spanning more than 45,000 square feet, it is the largest green roof on an existing building in Philadelphia. The planting design for the PECO roof contrasts low-growing, non-native succulents over the extensive area with native perennials and ornamental grasses in the planting beds surrounding the viewing deck.
PHS leads public tours of the green roof on the third Tuesday of each month, April through October, at 5 pm. The fee for tours is $5 for PHS members and $10 for nonmembers. Pre-registration and payment are required two days in advance of the tour. Participants must be 18 years of age, and there is a limit of 25 people per tour. The tours meet in the lobby at the PECO building, and include a short orientation followed by the tour. For more information, please contact PHS here or call Carol Dutill at 215-988-8869.
