About this file
This document summarizes the results of a grain size analysis conducted for the U.S. Army Corps of Engineers' proposed maintenance dredging of the Sandy Hook Channel in New York Harbor. The analysis involved taking sediment core samples from nine locations within the channel and analyzing the grain size distribution of composite samples from each location. The dredging project will remove approximately 200,000 cubic yards of primarily sandy and gravelly material from the channel to restore it to the authorized depth of 35 feet below MLLW plus a 2-foot overdepth allowance. Dredged material will be placed in the Sea Bright Offshore Borrow Area or at an upland site provided by the contractor. The solicitation for the dredging contract is expected to be available in June 2023 with a bid opening in July and contract award in August. The contractor must commence work within 5 days of notice to proceed and complete dredging within 32 days, maintaining a production rate of at least 8,000 cubic yards per day. Liquidated damages of $2,693 per day will be assessed for delays in project completion. The work is estimated to cost between $1 million and $5 million.
