About this file
This file comprises technical construction plans and profiles for the Lake Linden Trail Restoration project prepared by the State of Michigan Department of Technology, Management and Budget, Facilities and Business Services Administration, Design and Construction Division, located in Hancock, Michigan. The project involves the restoration and reconstruction of a trail segment designated as 7136-20-0040, with a 60-foot right-of-way spanning from station 676+00 to station 682+00. The proposed work includes an 8-inch aggregate surface trail with a 14-foot width centered on the existing trail, installation of a 36-inch culvert with a Class A end section, slope restoration of Type D classification, plunge pool construction, drainage improvements including a diversion ditch for erosion control, and clearing operations limited to 14 feet on either side of the trail centerline. The plans specify a proposed grade at 2.30% relative to the culvert location, with vertical curve data indicating a high point elevation of 630.97 feet and a point of vertical curve at elevation 631.06 feet. The contractor is required to coordinate with the utility company for protection and final location of an existing fiber optic line in the project area.
The technical specifications indicate standard detail references contained on sheets 36 and 37 of the complete plan set, with critical underground utility cautions noted throughout. The project incorporates erosion control measures including discharge bypass pumping into riprap ditch and upland stream channel diversion, with these erosion control costs to be paid separately. Site conditions show existing drainage patterns and clearing limits typical to the proposed trail width, with graphical scale provided at both full and half scales for plan interpretation. The document was prepared on March 28, 2023, and references design file path P:\7101_7200\7136200040_Lake_Linden_Trail_Restoration_, indicating this represents one segment of a larger multi-phase trail restoration initiative.
