FOW Sustainable Trails Initiative

Project details

  • Project Name: FOW Sustainable Trails Initiative (Stages 1 & 2)
  • Project Client: Friends of the Wissahickon
  • Project Location: Philadelphia, Pennsylvania

Friends of the Wissahickon developed the Sustainable Trails Initiative (STI) with a goal to monitor and enhance the existing 50-mile natural surface trail system throughout the park.

A.D. Marble served as the prime for Phase 3 (Construction) of the STI initiative. Phase I (assessment) included monitoring the trails, assessment of stormwater impacts, and development of sustainable trail ratings. Phase II (planning) involved the development of sustainability trail mapping, park signage, public meetings, and two demonstration trail-building projects.

The Stage 1 trail section is located from the Bells Mills parking lot downstream to the covered bridge. The entire trail network within Stage 1 is approximately 1.25 miles long; however, 0.25 mile of this section included trail closures. The goal of this trail enhancement stage was to install measures to improve its stability and reduce erosion associated with seeps and stormwater runoff. In addition, this section was constructed to provide Americans with Disabilities Act (ADA) accessibility to a picnic pavilion and also included trail signage.

Stage II is a 3-mile trail section that required re-routes, trail armoring, removal of pedestrian bridges, and the installation of three rock staircases to direct traffic along Cresheim Creek and access Wissahickon Creek. The project also required the completion of a hydrologic and hydraulic study for a proposed pedestrian bridge over Cresheim Creek.
