About this file

This is a construction plan document prepared by the State of Michigan Department of Technology, Management and Budget, Facilities and Business Services Administration, Design and Construction Division for the Lake Linden Trail Restoration project (Project ID: 7136-20-0040). The plans detail proposed trail improvements along a segment of the Lake Linden Trail, including the installation of culverts, slope restoration, riprap placement, and plunge pool construction. The project encompasses trail work from station 658+50 to station 664+50, with trail width standardized at 14 feet centered on the existing trail alignment. Key infrastructure elements include a 48-inch class A aggregate surface culvert with an 8-inch elevation change, a 12-foot by 5-foot precast concrete box culvert, and various grade transitions with slope percentages ranging from 0.31% to 2.12%. The plans indicate approximate excavation limits and require contractor coordination with utility companies for protection and final location of an existing fiber optic line positioned within the project area.

The technical specifications include vertical curve calculations with stationing and elevation data, graphic scales for plan and profile views, and notation of a 60-foot right-of-way. The document incorporates standard "Call Before You Dig" safety notifications and indicates this represents the first bid package of the overall trail restoration initiative. Construction details reference additional sheets within the specification set (Detail 1 on Sheet 36 and plunge pool details on Sheet 37), suggesting a comprehensive design package accompanies these plans. The design was completed on March 28, 2023, and prepared by OHM-Advisors, an architecture, engineering, and planning firm, with the project administered from the state facilities office in Hancock, Michigan.
