UNIVERSAL ACCESS TRAIL CONSTRUCTION AT THE ROCK CREEK CONFLUENCE PROPERTY - MT
Project Description: Five Valleys is seeking proposals from qualified entities to construct 5,100 linear feet of universal access trail at the Confluence property beginning in Fall 2023. This includes the “Confluence Gateway Trail” (see Appendix B map) and the “Wetland Discovery Loop Trail” (see Appendix C map). Along the existing 1/3-mile (approximately 1,850 linear feet) gravel trail, the contractor will excavate existing tread material; install geotextile; and install, crown, and compact aggregate tread. The remainder of the trail (approximately 3,250 linear feet) will be new construction where the contractor will excavate, bench cut where necessary, install geotextile, and install and compact aggregate tread.
The goal of the project is to create a sustainable trail system that is optimized for use by people of all abilities and mobilities, including people who use wheelchairs and people who are blind or who have low vision. The trail should be built in a manner that minimizes impacts to the natural environment. General universal trail design parameters are included in Appendix D. More information on universal trails can be found in Penn Trails publication “Trails for All People: Guidance for Accessibility and Inclusive Design.”

Additional Project Bid Information: PROJECT BACKGROUND:
Five Valleys Land Trust (Five Valleys) is a non-profit 501(c)(3) organization based in Missoula, MT. Five Valleys owns and manages the 300-acre Confluence Property, located at the confluence of Rock Creek and the Clark Fork River east of Clinton, MT and directly south of Interstate 90. Rich in history, the site was once slated to be developed into a residential subdivision. Initial work undertaken for the development resulted in substantial disturbance on site, creating a large pond and conditions that resulted in the proliferation of non-native and noxious invasive plant species. For the last ten years, Five Valleys has undertaken extensive efforts to restore habitat in these disturbed areas and establish trails and related visitor services. An existing 1/3-mile gravel pedestrian trail exists on site, accessed from the main trailhead and parking area along Rock Creek Road.
