Olsen Associates, Inc. is the Engineer-of-Record for a shoreline stabilization and marsh restoration project adjacent to the 18th Green of Harbour Town Golf Links on Calibogue Sound at Hilton Head Island, SC.  The project, which is required to address high shoreline retreat rates and extensive spartina marsh loss, will include the construction of six detached rock breakwaters, sand fill, and the planting of more than 3 acres of Spartina alternifloramarsh grass.  To minimize impacts to the highly developed residential community, golf course, and golf course operations, all equipment and materials will be transported to the project site by barge and all work will be performed from water and a floating plant.  The project, a first of its kind in the State of South Carolina, will be monitored for shoreline performance and marsh grass success.
