President's Budget for FY 2020 $200,000


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 and economical movement of goods between major deep draft ports that cannot be moved via highway or rail.  The current controlling depth of the project is -2 feet below MLLW.

ACTIVITIES COMPLETED FOR FY2019Award the beneficial use pilot project contract and perform dredging in Jekyll Creek for the beneficial use of dredged material pilot project and perform  maintenance dredging in the next three most critical sections; Buttermilk Sound, Hell Gate, and Field Cut.  Also conduct minimal caretaker activities, i.e. condition surveys and minor project operations.

ACTIVITIES FOR FY2020Conduct minimal caretaker activities, i.e. condition surveys and minor project operations.  Award the beneficial use pilot project contract.

ISSUES AND OTHER INFORMATION: There are nine major shoaling areas along the Georgia portion of the AIWW.  Hell Gate was dredged in FY 2009; Florida Passage, Buttermilk and Altamaha Sounds, and Fields Cut were dredged in FY 2010.  No dredging activities have been performed since FY 2010 resulting in continued shoaling and increased safety risks due to groundings and possible environmental impacts to natural resources.  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 pilot project is being coordinated 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.
