USA: Dredging Plan for Kings Bay Entrance Channel Unveiled

Dredging Plan for Kings Bay Entrance Channel Unveiled

U.S. Army Corps of Engineers has announced details about the maintenance dredging project at the Kings Bay Entrance Channel.

Base work consists of maintenance dredging of Kings Bay Entrance Channel from Station 80+00 to Station 350+00 to a required depth of 49 feet.

Option A consists of dredging shoal material of the North Settling Basin (NSB) to a required depth of 39 feet. Dredged material from the Entrance Channel is either placed on the beach or disposed of at the Ocean Disposal Area.

Beach compatible material will be placed in the North Beach Disposal Area (D/A-NB) as shown on the drawings and will be excavated within Stations 100+00 to 200+00 of the base dredging portion of the contract and entirely within Option A-NSB. The D/A-NB is located approximately 3.5 miles from the dredging area.

Non-beach compatible material is found entirely within the base and will be placed in the Fernandina Ocean Disposal Area (D/A-O). D/A-O is approximately 14 miles southeast of the dredging areas. This contract incorporates two feet of allowable overdepth throughout. Incidental work includes endangered species monitoring, sea turtle non-capture trawl sweeping, turbidity monitoring, beach tilling, and vibration monitoring.

Only hopper dredges will be allowed to work on this task order. Only Coast Guard Certified Hopper Dredges will be allowed to work on this task order. The dredging work is located at the Kings Bay Entrance Channel (KBEC). Kings Bay is 31 miles north of Jacksonville, Florida and 30 miles south of Brunswick Georgia.

The entrance channel separates Amelia Island, Florida to the south from Cumberland Island, Georgia to the North. The Entrance Channel is the main ocean entrance to the US Navy Submarine Base at Kings Bay Georgia and also provides access between the Atlantic Ocean and the Atlantic Intracoastal Waterway (AIWW).

Magnitude of Construction is between $10,000,000.00 and $25,000,000.00.
