Project work includes construction of a dune and beach berm along approximately 3.4 miles of shoreline in St. Lucie County between Florida Department of Environmental Protection (FDEP) Range Monuments R-98 in St. Lucie County and R-01 in Martin County. Beach compatible sand will be dredged from borrow area A1 and A2, located approximately 3.5 nautical miles offshore in Federal waters. Due to the extensive hardbottom areas located offshore of the fill area, offshore pipeline access is limited to specified corridors. Work also includes but is not limited to endangered species observers (hopper dredges only), sea turtle trawling (hopper dredges only), turbidity monitoring, beach tilling, beach fill quality control, screening, MEC construction support, and vibration control and monitoring.
