Jacksonville Harbor, 47-Foot Deepening Project, Contract C, Duval County, Florida

The Jacksonville Harbor Federal navigation project encompasses approximately 20 river miles from the mouth of the St. Johns River at Mayport to the Talleyrand terminal near downtown Jacksonville. The current authorized channel depth is 40 feet for the main channel and 38 feet for the West Blount Island Channel. Channel improvements will allow existing fleet and new deeper draft vessels to utilize the channel more efficiently and safely, thereby reducing transportation cost. The Recommended Plan (preferred alternative) is the locally preferred plan (LPP) of 47-feet MLLW as identified in the 16 April 2014 Chiefs Report. This plan includes deepening from the existing 40-foot channel to 47 feet from the entrance channel to approximately River Mile 13. The following areas of widening are included as part of the new channel footprint for the LPP: • Mile Point: Widen to the north by 200 feet from Cuts 8 to 13 (~River Miles 3 to 5). • Training Wall Reach: Widen to the south 100 feet from Cuts 14 to 16 (~River Miles 5 to 6) transitioning to 250 feet for Cut 17 (~River Mile 6) and back to 100 feet from Cuts 18 to 19 (~River Mile 6). St. Johns Bluff Reach: Widen both sides of the channel varying amounts up to 300 feetfrom Cuts 40 to 41 (~River Miles 7 to 8). The following turning basin areas are included in the Recommended Plan. •Blount Island: ~2,700 feet long by 1,500 feet wide located in Cut 42 (~River Mile 10). •Brills Cut: ~2,500 feet long by 1,500 feet wide located in Cut 45 (~River Mile 13) Construction of the recommended plan involves dredging of approximately 18 million cubic yards of material. All material dredged for construction will to go to the Ocean Dredged Material Disposal Site (ODMDS) located approximately 7.7 nautical miles offshore. Coast Guard Certification is required.
