GrimDeeper was contracted to perform third-party turbidity monitoring on this beach renourishment and protection project. The City of Boca Raton was the customer, in partnership with The Greater Beach & Park District, Florida Department of Environmental Protection (FDEP), and Palm Beach County. Weeks Marine, Inc. was the prime dredging contractor.
The North Boca Raton Beach Renourishment project initially started in March 2016, but stopped in April 2016 for sea turtle nesting. The project involved the dredging and placement of approximately 104,000 cubic yards of material from various offshore borrow areas to fill approximately 1,100 linear feet of shoreline north of the Boca Inlet, utilizing the Cutter Suction Dredge (CSD) “R.S. WEEKS”. The borrow areas are situated between inner and outer reef complexes, which required particular attention during construction.
Additional monitoring at the reef locations was sometimes required, depending on the proximity of the dredge to the hard bottom resources. Scientific diver surveys were also being performed (by another vendor), and coordination with all equipment was necessary to ensure their safety. Turbidity monitoring included sampling at the borrow areas, hard bottom locations, and beach fill sites, three times daily (12-hour schedule).
The project resumed in February 2017 and completed March 2017. The project involved the dredging and placement of approximately 400,000 cubic yards of material from various offshore borrow areas to fill approximately 4,000 linear feet of shoreline north of the Boca Inlet, utilizing the Cutter Suction Dredge (CSD) “C.R. McCASKILL”. Turbidity monitoring included sampling at the borrow areas, hard bottom locations, and beach fill sites, three times daily (12-hour schedule).
