Atlantic Intracoastal Waterway, GA

PROJECT NAME AND STATE:  Atlantic Intracoastal Waterway, GA

AUTHORIZATION:  Rivers and Harbors Act of 1880, as amended.



Allocation for FY 2015


Allocation for FY 2016


Allocation for FY 2017


Supplemental funds for FY 2017


President's Budget for FY 2018


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 FY2017Performed minimal caretaker activities, i.e. condition surveys and minor project operations.  Prepared plans and specifications for a regional sediment management pilot project for Jekyll Creek material and maintenance dredging of additional sites.

ACTIVITIES FOR FY2018Conduct minimal caretaker activities, i.e. condition surveys and minor project operations.  Award the beneficial use pilot project contract.

ISSUES AND OTHER INFORMATIONThere 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.
