10 Dredge ILLINOIS 30 inch discharge diameter Capable of pumping 2500 cubic yards of sand 25,000 feet per hour Great Lakes Dredge and Dock Company

11 Schedule 90 Day contract time Mobilized second week of April Begin pumping second week of May End pumping second week of June Demobilize third week of June

12 What To Expect Pipeline on the beach Closing of a minimum 1000 foot sections of beach –Provide public safety and adequate staging 24 hour operation with continuous State inspection Structure Monitoring –Contractor will set up vibration monitors adjacent to structures

13 Environmental Concerns Piping Plover –Current conditions not favorable for plover habitat but they have historically used the area Shipwrecks –Known Cultural Resources Outside of Project Area Munitions/Debris –Double Screening At Cutterhead At Discharge Pipe
