Abstract: The U.S. Army Corps of Engineers {Corps), Jacksonville District, proposes to continue conducting routine maintenance dredging of Fernandina Harbor, Nassau County, Florida. Approximately 300,000 cubic yards of sediment, resulting from shoaling, will be removed from the harbor's entrance channel on an annual basis. The harbor's inner channel and turning basin will also require dredging every 5 to 10 years. An estimated 300,000 cubic yards of additional material will be removed from these locations during each dredge event. Various types of dredging equipment, possibly including a hopper , dredge, will be used to accomplish the above tasks. Excavated material consisting of suitable sand may be placed at _several different beach locations on Amelia Island. Any dredged material not suitable for beach placement will be taken to the Fernandina Ocean Dredged Material and Disposal Site (ODMDS) or the Nearshore Disposal Area. Periodic removal of accumulated sediments from the entrance channel, inner channel, and turning basin allows commercial vessels and recreational boats access to the port of Fernandina. Dredging the entrance channel also serves the navigational needs of the Navy's Trident submarines stationed at King's Bay, Georgia. This Environmental Assessment will evaluate whether to conduct the maintenance dredging and, if so, where the dredged material should be placed.
