Jacksonville Harbor Maintenance Dredging, 2018
On behalf of the U.S. Army Corps of Engineers, Jacksonville District, Cashman was contracted to conduct maintenance dredging of 38- and 40-foot projects (Cut-7 through Cut-45, Cut-55, Cut-G, and the Lower Terminal Channel) at various locations within Jacksonville harbor. This allows larger vessels to access the channel, reducing transportation costs, providing increased navigational safety, while avoiding or minimizing impacts to environmental resources.
