Park Trail

Campbell Grading Inc. was selected to design and construct 3,500 linear feet by 6 feet wide outdoor accessible trail in the Presidio. The Park Trail acts as the main north-south pedestrian way through the middle of the Presidio. The trail runs from the Mountain Lake trail on Washington (near the golf course), semi-parallels Park Boulevard, crosses Lincoln Boulevard, and continues down to intersect the Promenade Trail (west of McDowell). The trail design provides important views and reflection points of the San Francisco National Cemetery, Historic Forest, and Presidio Habitats art installation.  From May 2010 to May 2011 eleven Presidio Habitats art installations were on display in the Presidio, two of which were on Park Trail. These installations were site-specific art exhibitions that celebrated the wildlife that inhabits the Presidio.

The Park Trail goes through the Historic Forest, a large stand of cypress and the most photographed forest in the Presidio. This landscape is highly sensitive to change, although with Barth's extensive experience and reputation for successfully working within highly constrained and sensitive landscapes Campbell Grading Inc was entrusted to do work in this area. An outdoor accessible grade trail was built through the cypress stand, removing and repairing the extensive network of social trails and erosion gullies that had formed over the years. The decommissioning, erosion control, and restoration work throughout the entire Park Trail project utilized the trees that were removed in order to create enough room for this accessible trail.

The completed trail was surfaced with 920 tons of amended chert shale tread surface. This tread surface is engineered and developed by Campbell Grading, Inc. Additionally, we built a 16 linear foot bridge overlooking the San Francisco National Cemetery, several hundred feet of sutter wall, and sustainably-harvested redwood railings. All of Campbell Grading, Inc's trail construction methods/techniques were, and still are, specially engineered to minimize environmental impact.
