Abstract: The U.S. Army Corps Engineers, Jacksonville District (Corps) in partnership with its non-federal sponsor, the Jacksonville Port Authority (JAXPORT), proposes to improve berthing areas located within Jacksonville Harbor, Florida. In short, the work would include deepening Blount Island Berths 30 through 35 and Dames Point Berths 16 through 18. These berths are currently constructed to -40 feet plus 2 feet of depth, and would be deepened to -47 feet plus 2 feet of depth. An estimated 1,301,521 cubic yards of sediment and rock would be dredged from the berths and placed within the designated Ocean Dredged Material Disposal Site (ODMDS) or upland placement locations (Bartram or Buck Island Dredged Material Management Area (DMMA)). Periodic maintenance dredging will also be required to remove accumulated sediments and maintain the depth of the berthing area for navigation purposes. Excavated material from future maintenance dredging events may be placed either within the designated ODMDS or Bartram or Buck Island DMMAs. Maintenance dredging is expected to occur on an annual basis and will be completed by JAXPORT; however, frequency may vary due to storm induced shoaling and availability of funds. Berthing area costs associated with federal harbor projects, whether construction costs or maintenance costs, are generally paid in total by others, not the Federal government. In this case, JAXPORT will be paying 100% for deepening of the berths. However, construction or maintenance dredging at berthing areas, and placement of that material, sometimes occurs simultaneously with dredging of a Federal channel.
