CHARLESTON, S.C. -- The U.S. Army Corps of Engineers has completed taking samples from Charleston Harbor to see what sort of material must be removed for the planned deepening of the harbor.
Corps officials are meeting with the media Friday to discuss what they have found.
The samples are needed before work can begin on the deepening, which could cost $350 million.
Rocks could require blasting and increase the time and cost of the project,
Maritime interests want the channel deepened from its current 45 feet to 50 feet to handle larger container ships that will routinely visit once the widened Panama Canal is open in 2015.
