Harbour Isles Marina is located at the Fort Pierce Inlet’s mouth and accommodates yachts up to 120 feet in length in the area’s best seawall-enclosed and wind protected harbor. The harbor was dredged to create a protected harbor on Hutchinson Island at the Fort Pierce Inlet and utilizes a series of structural bulkhead systems.

The two 165-foot jetties utilize a steel sheet pile wall with concrete batter piles and a concrete cap. The batter piles are located on the outside of the navigation channel to avoid interference. At the throat of the harbor, 215 feet of rock riprap was used to protect the shoreline. The riprap system transitions to a 4,300-foot-long, tied-back concrete sheet, and king pile seawall designed to accommodate the four-story condominiums surrounding the harbor.

WGI also provided construction phase services for this project, including shop drawing review, RFI responses, and attending pre-construction meetings and periodic milestone meetings. WGI was on-site during construction to observe all construction activities, including concrete placement, pile installation, and floating dock installation. Being the engineer of record and CEI for this project allowed WGI to quickly and efficiently solve any construction-related issues that arose during construction.
