T he Rybovich Marina Redevelopment project in West Palm Beach transformed the waterfront in the City. The marina includes 147 wet slips to accommodate megayachts. Coastal Systems designed the following marine works for the project:
- 3,400 linear feet of steel sheet piling bulkhead
- 125,000 cubic yards of dredging
- Dredged material placement areas near Little Munyon Island
- Concrete piers for the 660-ton marine travelift
Coastal Systems performed a site-specific coastal engineering study to provide design loads for the concrete floating docks proposed for the marina. Numerical modeling utilizing the MIKE-21 software was conducted to evaluate wave attenuation for the marina. Tidal currents were also simulated with the MIKE-21 hydrodynamic model to evaluate flushing and to provide design criteria for vessel navigation. The design effort required a multi-disciplined team coordinating between the marine works contractor, floating dock manufacturer, upland civil engineers, architects and specialty boatyard consultants.
As part of the marina environmental permitting, Coastal Systems collaborated with the marina owner to develop site plans that would avoid and minimize impacts to seagrass. A site alternatives analysis was prepared and detailed marine resource and hydrographic surveys were conducted within the existing and proposed marina basin areas, as well as along the access corridors. Coastal Systems coordinated with marina and regulatory agencies to design mitigation and habitat restoration for the unavoidable impacts using the UMAM. Mitigation included seagrass habitat restoration offsite through the use of clean dredged material from the Project expansion area to fill a 2.9-acre dredge hole, as well as protection of adjacent seagrass habitat and out-of-kind native wetland/upland habitat restoration at Little Munyon Island.
Construction administration services were provided for the marine works that were completed in phases between 2007-2010. Rybovich is FDEP designated Clean Marina, FDEP designated Clean Vessel Act Compliance Pump-Out Facility and FDEP Clean Boatyard.
