For years people in West Philly have walked past Squirrel Hill Falls Park on the northwest corner of 48th and Chester and wondered what had happened.

The former vacant lot, which was transformed into a neighborhood gem complete with a mural, solar-powered waterfall, seating, lighting and sound system 15 years ago, is now just a dressed-up, locked-down vacant lot again. But the park’s controversial history will take a turn for the better this week when a group of volunteers will meet there on Sunday from 1 p.m. to 5 p.m. to clean the lot up and try to make it a park again.

The park was the brainchild of West Philly artist Danielle Rousseau Hunter, whose name is still emblazoned in large letters on the park’s grand metal entrance gate. Hunter raised hundreds of thousands of dollars from a fairly astonishing list of donors (see the full story here and here) to design and build the park, which includes a three-story waterfall mural on the side of an apartment building.

The park opened with a black tie ceremony in September 1996. Since then many residents say Hunter has treated it like her fiefdom, locking it and only allowing visitors to enter under her supervision. But for many years the park has not been used and is now littered with trash and debris and overgrown with weeds. A bicycle cable lock still keeps the front gate closed.

But contrary to popular belief, Hunter does not own the land, the Friends Rehabilitation Program Inc., an affordable housing provider located at 247 S. 48th St., does. One or two people there have taken a renewed interest in the park and have been able to get insurance to again allow limited access. There are no plans for an official “opening” of the park, although if there is community interest more access could be possible in the future.

The first step is Sunday’s clean-up. Volunteers and some equipment, particularly garbage bags and garden disposal bag (the big paper ones) are still needed. There is no need to RSVP or anything. Just show up. They could use the help.
