Summary: In July 2015, the Savannah District awarded a contract to begin building dissolved oxygen injection system systems upstream on Plant McIntosh and downstream of Hutchinson Island. Both of the plants are completed and testing process was completed in September 2020. Status: Awarded $99.6 million contract to CDM Constructors Inc. The final batches of conserved artifacts were sent to the U.S. Archeologists recovered more than 30,000 artifacts, most of which are related to the mechanics of the vessel. The Corps of Engineers removed the remains from their location to protect them from further damage. Construction began in January 2015 when archaeologists mobilized for the first contract on the recovery of the CSS Georgia ironclad. The CSS Georgia’s location impeded the channel expansion. Summary: The remains of the CSS Georgia, a Confederate ship, previously rested on the bottom of the Savannah River adjacent to the shipping channel, near Old Fort Jackson. Conservation was completed by Texas A&M University’s Conservation Research Laboratory. ![]() Navy, which owns the vessel, recovered major pieces of the ironclad. Panamerican Consultants of Memphis, Tennessee conducted field work. Data collection contract was awarded to Dial Cordy and Associates of Jacksonville, Florida. Status: Recovery and conversation is completed. ![]() Inner harbor work will also include constructing three bend wideners and two meeting areas, and enlarging the Kings Island Turning Basin at the Garden City Terminal. This deepening will allow larger, more efficient container vessels to use the East Coast’s second busiest container harbor with fewer weight and tidal restrictions. Summary: The SHEP will deepen the Savannah harbor and the associated shipping channel from an authorized depth of 42 feet to 47 feet. Status: First of two contracts awarded to Norfolk Dredging Company completed in August 2021 Second contract awarded to Weeks Marine in November 2019 and work is approximately 94% completed. Dredging the outer harbor is the first step to deepening the entire 40-mile shipping channel and harbor from deep ocean to the Georgia Ports Authority terminal in Garden City. The contract covers extending the entrance channel by 7 miles, and deepening of the outer harbor from approximately Fort Pulaski for 18.5 miles into the Atlantic Ocean. 10, 2015 to begin deepening the harbor from its current 42-foot depth to 47 feet (slightly deeper in the ocean end of the harbor). Summary: The Dredge Alaska moved into the Atlantic Ocean Sept. The $134.5 million contract was executed by Great Lakes Dredge & Dock Company of Oak Brook, Illinois These breaking waves are extremely hazardous to incoming, and outgoing vessels and pose a particular danger to individuals walking on either of the jetties.Began January 2015, completed in January 2022īegan September 2015, complete March 2018īegan September 29, 2019, complete March 2022 Shoaling conditions caused by littoral sand drift produce dangerous and unpredictable breaking wave formations at the harbor’s entrance. Impeding sand is then dredged from the entrance channel and deposited in the inter-tidal zone where the existing littoral drift carries it down-coast, nourishing those beaches east of the Santa Cruz Harbor entrance.īecause of sand incursion at the mouth of the harbor, it is essential that an annual dredging effort be maintained to assure sufficient depth at the harbor entrance to permit the safe passage of vessels transiting the entrance. Constantly moving, the sand mass builds up against the west jetty and flows around it, shoaling the Santa Cruz Harbor entrance channel. Sand indicated by orange dotted areas, is carried down the San Lorenzo River and thence moved down-coast by wave and tidal action called littoral drift. This constant movement of masses of sand is termed littoral drift. The amount of material moved and deposited is directly proportional to the severity of current and wave conditions. Such movement is generated by the ongoing forces of waves and currents. Dredging of the harbor is required because of the constant easterly movement of sand along our coast and thus, across our harbor entrance.
