About this file
This file 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 No. 7136-20-0040). The document presents detailed engineering plans and profiles for Segment 1 of the proposed trail, spanning from Station 670+00 to Station 676+00, and includes specifications for trail surface construction, grading, drainage infrastructure, and utility coordination. The plans specify an 8-inch aggregate surface trail with slope restoration (Type D), a 60-inch diameter culvert (Class A), and a plunge pool with associated erosion control measures. Key elevation data, vertical curve calculations, and grade percentages are provided throughout the profile, with proposed trail centerline grades ranging from approximately -2.01% to 0.67%. The project location is in Hancock, Michigan, with site access from Woodside Lane, First Street, and Montreal Road.
The construction plans indicate contractor responsibilities for coordinating with utility companies regarding an existing fiber optic line and implementing erosion control measures including diversion ditches and bypass pumping if streamflow occurs during work activities. Dewatering of scour holes is identified as incidental to other pay items on the site. The document emphasizes utility location awareness with the "Call Before You Dig" notation and specifies underground utility caution for critical infrastructure. The plans were last revised on March 28, 2023, and were prepared by OHM Advisors, with oversight by Adam P. Lach, RA, Director of the Design and Construction Division at 424 Hancock Street, Hancock, Michigan 49930.
