The idea for an 11-mile Greenway along the Delaware River in Philadelphia goes all the way back to 1995, with U.S. Rep. Bob Borski's vision for reconnecting northeast Philly neighborhoods with the riverfront. Kensington native Mariann "Mare" Dempsey was in on the plan from the beginning as an aide to Congressman Borski, and over the following decades she helped guide the Greenway through thickets of red tape and litigation to become a reality. On the occasion of her retirement this year, PEC's Patrick Starr (another early leader in the initiative) reminisces with Dempsey about the journey they've shared.
