LOCATION AND DESCRIPTION:  The Savannah District’s portion of the Atlantic Intracoastal Waterway consists of 161 miles of shallow draft channel from Port Royal Sound, SC to Cumberland Sound, FL.  The authorized depth of the project is -12 ft Mean Lower Low Water (MLLW).  The project provides safe movement of goods between major deep draft ports and offers vast recreational opportunities. The current controlling depth of the project is -3 feet below MLLW. 

ACTIVITIES COMPLETED FOR FY2022Conduct maintenance dredging of two critical reaches on the waterway.  Conduct minimal caretaker activities, i.e., condition surveys and minor project operations.  Prepare plans and specifications for a small maintenance dredging contract.  Continue monitoring activities for beneficial use pilot project contract. 

ACTIVITIES FOR FY2023:  Conduct maintenance dredging of two critical reaches on the waterway.  Conduct minimal caretaker activities, i.e., condition surveys and minor project operations.  Prepare plans and specifications for a small maintenance dredging contract. Continue monitoring activities for beneficial use pilot project contract.

ISSUES AND OTHER INFORMATION:  There are some major shoaling areas along the Georgia portion of the AIWW.  Jekyll Creek, Buttermilk Sound, Hell Gate, Fields Cut were dredged in FY 2019.  Elba Cut and Altamaha sound were dredged in FY2022.  Lack of environmentally acceptable disposal areas would limit dredging to only certain reaches should funding become available.  Vessel traffic must rely on accurate surveys and the Georgia Coast’s 7.0-foot tidal range in order to utilize the AIWW.  The District is coordinating with all resource agencies to find an alternate method of placement of dredged material that is cost efficient yet environmentally sound. 

ADMINISTRATION POSITION:  Project is consistent with current Administration policy.
