St. Johns River, U.S. Coast Guard Station Mayport, Sector Jacksonville, Florida; Restricted Area

The U.S. Army Corps of Engineers (Corps) is amending its restricted area/danger zone regulations to establish a new restricted area in the waters surrounding U.S. Coast Guard Sector Jacksonville facilities at Station Mayport, Jacksonville, Florida (Station Mayport). Station Mayport is situated on the south side of the St. Johns River which, as the primary federal navigable channel entering the Port of Jacksonville, is heavily transited by commercial and recreational vessels. This United States Coast Guard (USCG) facility maintains a high operational tempo for both routine and emergency operations. This amendment to the existing regulations is necessary to enhance the USCG's ability to counter postulated threats against their personnel, equipment, cutters and facilities by providing a stand-off buffer encompassing the waters immediately contiguous to the Station Mayport. The amendment will also serve to protect the general public from injury or property damage during routine and emergency USCG operations and provide an explosive safety arc buffer during periodic transfer of ammunitions between units, including cutters.
