Florence renourishment project – PHASE III

Great Lakes Dredge & Dock (GLDD) is about to begin preparations for the Phase 3 of the Post-Florence Renourishment project.

According to Carteret County, GLDD is planning to mobilize land- and water-based pipe, heavy equipment, personnel, etc. starting this December with the dredging/pumping to begin in the final week of January 2021.

For the project, GLDD will use hopper dredges Liberty Island and Ellis Island. – similar to the Phase I and Phase II efforts in 2019 and 2020, respectively.

The dredge Liberty Island will arrive on-site first and will generally progress and “leapfrog” west to east in Central & East Emerald Isle. At some point in mid-March the larger hopper dredge, the Ellis Island will accompany the Liberty Island and serve the Bogue Inlet Ocean Reach, the county said.

Phase III of the Post Florence Renourishment Project will utilize 2,012,850 cubic yards (cy) of sand obtained from the Offshore Dredged Material Disposal Site (ODMDS) associated with Morehead City Federal Navigation Project.

The project includes four discrete reaches totaling 9.4 linear miles of beach in Emerald Isle – Bogue Inlet Ocean (166,350 cy), West Emerald Isle (708,750 cy), Central Emerald Isle (537,750 cy), and East Emerald Isle (600,000 cy).

The project is scheduled to be conducted between January 1 to April 30, 2021, when environmental window closes for the sea turtle nesting season and other biological resources.
