About this file

This presentation outlines maintenance dredging projects for the Jacksonville Harbor and U.S. Naval Station Mayport in Florida. The projects involve dredging portions of the federal channels for both locations to depths of 47 feet and 50 feet respectively. Material dredged from specific portions of the Jacksonville Harbor channel will be disposed of at the Jacksonville Offshore Dredged Material Disposal Area or placed on Mayport Beach, subject to screening requirements. The Naval Station Mayport project will place all dredged material in the Jacksonville disposal area. The presentation provides details on dredging areas and depths for both projects, identifies adjacent construction work, and is intended to coordinate the related efforts.

The related federal contract opportunity is solicitation number GROUP1-18-R-J028 from the Department of the Army Corps of Engineers Engineering District Jacksonville for maintenance dredging of the U.S. Naval Station Mayport to a depth of 50 feet, and the Jacksonville Harbor to 47 feet. Dredged materials will be disposed of as indicated on the drawings.
