Collaboration among neighboring municipalities doesn’t always happen in Western Pennsylvania. But for more than a year now, the Planning Directors of several North Hills communities have been working together on creating a regional trail system. And their numbers are growing. Just last week, the Borough of Bradford Woods joined with Cranberry, Pine, Marshall, Jackson, and Adams as part of the area’s Planners in Action group. At its October 26 meeting, Cranberry’s Board of Supervisors agreed to hear a presentation at its regular meeting on November 2 updating the planning group’s efforts.
