McMahon, in collaboration with the Brandywine Conservancy, led development of a multi-municipal trail plan in central Chester County.. The project included evaluation of alignment options and development of conceptual plans for over nine miles of continuous bicycle and pedestrian facilities connecting the Struble Trail, Hibernia County Park, and destinations in between. The project included analysis of existing conditions, evaluation of trail alignments and facility types, development of on-road design treatments, development of conceptual plans, property owner coordination, PennDOT and Chester County coordination, and wayfinding recommendations. The plan incorporates a broad range of bicycle and pedestrian facility types, such as off-road multi-use trails, shared lane on-road bicycle facilities, striped shoulders, and sidewalks. The trail corridor was divided into over 20 segments for implementation. The implementation plan includes next steps and funding strategies for priority trail segments.

Community engagement for the project included two community workshops, four study task force meetings, and individual property owner coordination meetings. At the community workshop, table-top mapping exercises allowed participants to play an active role in the planning process by drawing and providing comments on draft conceptual plans.
