Location: Fort Clinch State Park; Fernandina Beach, Florida

Client: State of Florida, Div. of Parks & Recreation, Florida Park Service

This project required the construction and rehabilitation of five (5) rock groins located seaward of historic Fort Clinch, near the Florida/Georgia border.  Fort Clinch was constructed in 1847 and has been constantly endangered by erosion due to its location along the dynamic shoreline of the St. Marys River Entrance.  Olsen Associates, Inc. was the Engineer of Record for this project, performing all aspects of design, permitting, construction review and performance monitoring.  The firm likewise provided liaison required for sand placement to the beach and completed groin field from maintenance dredging of the adjacent navigation channel by the U.S. Army Corps of Engineers.  Construction of the rock groins was completed in 2000 at a cost of $1.7M.  Since then, Olsen Associates, Inc. has continued to assist with the planning and permitting of work to place maintenance dredged sand from the federal navigation channel onto the Fort Clinch shoreline on an as-needed basis - typically every three years.
