PresqueIslePhaseI_1990_Part1.pdf

This is a set of engineering drawings from 1990 for Phase 1 of recreational boating facilities at Presque Isle Harbor, Michigan, prepared for the State of Michigan Department of Management and Budget Office of Facilities. The drawings include detailed plans for breakwater construction, site layouts, soil borings, and walkway details. The project encompasses the construction of northeast and south breakwaters, concrete walkways, and associated marine infrastructure. The documents include an index of 12 drawings covering site plans, soil borings, breakwater plans, cross-sections, concrete walkway details, and quantity sheets.

The drawings show detailed technical specifications including soil boring logs taken in September 1985, site topography and bathymetry, and construction details for 3-ton cover stone breakwaters with concrete walkways and handrails. The project location is specifically situated in Lake Huron at Presque Isle Harbor, with detailed plans showing both northeast and south breakwater components. The engineering drawings include precise measurements, elevations, and construction specifications that would be necessary for contractors to bid on and execute the marine infrastructure work.
