The State Ports Authority has finalized a $1 million land preservation program tied to its new container terminal being constructed at the former Navy base in North Charleston, officials said today.

The preservation program calls for the maritime agency to protect nearly 1,000 acres of environmental and historically significant properties in the Cooper River watershed, officials said.

There are three properties in the protection, including the 824-acre Buck Hall Plantation property, which is located on the west branch of the Cooper River adjacent to Mepkin Abbey. The property includes 375 acres of wetlands that will be preserved, SPA officials said.

This environmental program ties into its $12 million environmental mitigation plan, which the authority agreed to fund to help offset some of the negative effects of the $600 million shipping terminal it is building in North Charleston.
