Marinex To Dredge Savannah and Brunswick Inner Harbors
The Savannah Inner Harbor requires up to seven million cubic yards of annual maintenance dredging by cutterhead dredge, placing the material in eight diked disposal areas on the north side of the channel. Savannah's inner harbor channel is 21 miles long, 42 feet deep and 500 feet wide, with a sediment basin that allows removal of harbor sediment at a reduced cost.
The Brunswick Inner Harbor channels are maintained at 30 feet deep and 400 feet wide through St. Simon's Sound, Brunswick River and East River. Dredged material placement is at Andrews
Island, the sole upland disposal area.
