About this file
This is a design and construction document for trail rehabilitation at the Detroit River International Wildlife Refuge in Michigan, prepared by the U.S. Fish and Wildlife Service, Region 3 Engineering in Denver, Colorado.
The project involves rehabilitation of two trails within the refuge: the Green River Trail and the Walnut Grove Trail, both located in Wayne, Michigan. The rehabilitation work includes installation of gravel trail surfaces with specific construction details, installation of concrete decking at select locations, and transitions between proposed trails and existing concrete or improved surfaces. Key specifications include 4 inches of gravel base material with geofaric edging, 4 inches of concrete with expansion joints placed every 10 feet for deck areas, and transitions occurring at 1 inch elevation change over 1 linear foot. The document contains three sheets: a cover sheet with vicinity map and approval signature blocks, trail rehabilitation details with photographic references and cross-sectional diagrams, and deck rehabilitation details with plan views and section drawings. All construction is noted as "not to scale," and the document includes provisions for existing trails that may not be 8 feet in width to be widened where feasible to meet design standards.
