Ralston Center

Description

The Ralston Center, located adjacent to the University of Pennsylvania at 3615 Chestnut Street, is a 100-year old, three-story stone facility providing services for the elderly. As landscape improvements were made in two phases, Ralston elected to design the landscape to include stormwater management including two retrofit bio-retention areas to capture an existing parking lot, paths, and lawn in a combined sewer area. The site previously discharged directly to the combined sewer.

The first phase included the vegetated swale and expansive bio-retention area designed to capture an existing parking lot. The second phase reduced the lawn area and included a bio-retention area underlain by a stone infiltration bed. The site serves as an example of a retrofitted high-performing stormwater systems that meets the aesthetic expectations of a traditional landscape in a formal setting. The improvements were not required by regulation.
