In 2002, the Philadelphia Housing Authority partnered with the Philadelphia Water Department (PWD) on the redevelopment of the Mill Creek housing project, a 12.6 acre site located in West Philadelphia. The plan called for the demolition of 440 dilapidated public housing units and the construction of 360 new units.

The Mill Creek basin is prone to a variety of water-related issues, including combined sewer overflows, flooding, and subsidence from an underground stream. PWD’s role was to design a stormwater management plan that sought to prevent 100% of the runoff generated by new development from leaving the site. As implemented, the plan designed by Wallace Roberts & Todd, LLC, consists of a 2.6 acre on-site park that is underlain by a water detention/infiltration area. The park serves as an accessible public open space for the Mill Creek community, while it also functions as permeable surface area that allows runoff to seep down into the underground storage area. The storage area reduces the peak amount of runoff discharged to the Mill Creek storm sewer system.
