The Cresheim Valley below Germantown Avenue is part of Fairmount Park. The former railbed within it (see section below) is also an easement for PECO powerlines, which take advantage of the former railbed's grading and open space. In October 2013, the City of Philadelphia extended Fairmount Park ownership of the creek valley almost to the Philadelphia-Montgomery border at Stenton Avenue as part of the Wissahickon East Project, with ongoing and future efforts such as streambed cleanup and invasive species removal to restore the of newly acquired land.
