The Trexler Nature Preserve envisioned various trail development and improvement projects to make the preserve more accessible for pedestrians. The proposed trail system was developed as an interconnected system that allowed park users to navigate the expansive 1,108-acre preserve, which surrounds the 29-acre Lehigh Valley Zoo.
Benesch provided engineering design of the proposed recreational trails, several of which were designed in accordance with ADA standards. We located sites to design new bridge structures for pedestrians to cross the stream and rehabilitated existing bridges. This included retrofitting existing bridges to meet ADA accessibility standards. Benesch also designed boardwalks for wet areas, protective fencing, drainage and all environmental permitting including wetlands, Bog Turtles and cultural resource investigations.
In addition, the project included the engineering design and PennDOT Highway Occupancy Permitting of a proposed driveway improvement which would allow access for hunters to the remote North Range area, open for bowhunting.
Funding for the project was provided by a Pennsylvania Department of Conservation and Natural Resources (DCNR) grant. All park improvements were designed in accordance with DCNR specifications.
