About this file
This is a Plans Set document for the Lexington Harbor Marina Redevelopment project in Lexington, Michigan (Bid 751/17282), prepared by Edgewater Resources, LLC. The project scope encompasses dredging operations within Lexington Harbor with two designated dredge areas: Area A requiring a depth of 571.15' (NAVD88) with an estimated volume of 2,800 cubic yards, and Area B requiring a depth of 570.15' (NAVD88) with an estimated volume of 8,100 cubic yards. The total dredge volume including 2:1 side slopes is estimated at 11,600 cubic yards. The project includes temporary dredge disposal and dewatering operations at the existing MDNR boat launch parking lot located at 7390 Huron Avenue, Lexington, Michigan. Dredging controls and survey data utilize Michigan State Plane Grid coordinates with eleven defined control points (DP1-DP11) and are based on bathymetric surveys completed May 26, 2023, and legal boundary surveys completed November 20, 2024. Dredging must comply with turbidity curtain requirements as specified by EGLE and USACE permits, with a maximum allowable overdredge of 6 inches beyond required depths.
The plans include detailed specifications for sediment and erosion control (SESC) measures, including turbidity curtain placement, silt fencing with minimum 6-inch embedment and 5-foot maximum post spacing, and dewatering area management. Additional construction elements include gangway platform improvements with specifications for steel pile construction (12-inch diameter ASTM A252 Grade 3 steel pipe piles with 14-inch diameter steel plate caps), timber decking using Kebony material, and railing systems with hot-dip galvanized steel components. The contractor is responsible for all dredge material testing, final disposal site approval from the engineer, coordination with EGLE and USACE for alternate dewatering locations, restoration of disturbed areas and parking lot to pre-existing conditions, and coordination with other concurrent work within the harbor. The project plans set indicates project number 18-036 with a revision date of April 24, 2026.
