PresqueIslePhaseI_1990_Part4.pdf

This file contains engineering drawings and site plans from the Michigan Department of Natural Resources and Department of Management and Budget Office of Facilities for the Presque Isle Harbor project from 1990. The drawings include existing and proposed site plans, soil boring logs, dredging sections, and details for an information station structure. The project involves dredging work for a basin and entrance channel, with dredge depths specified at -6' and -10' LWD (Low Water Datum), as well as construction of launching ramps and associated facilities.

The technical drawings show detailed cross-sections at various stations (11+00 through 18+40), soil boring data from 5 test locations, and construction specifications for concrete work, staging areas, and temporary facilities. The site plans indicate a water surface elevation of 577.48 feet and include designated construction storage areas, prohibited areas, and specifications for silt screens and other environmental protection measures. The drawings also detail an information station structure with dimensional specifications and construction requirements that must comply with Michigan Department of Transportation 1984 Standard Specifications.
