BACKGROUND: Palm Beach County residents and the area’s vital marine industry will benefit from easier navigation following the completion of the IWW maintenance project. The FIND is committed to ensuring safe navigational waterways that allow for the passage of commercial and private vessels. The project will result in significant increased economic benefits while providing for continued operation of the area as a boating destination and international marine hub. In order to remain competitive with other emerging popular marine destinations, Palm Beach County waterways must remain open and accessible to all vessels. Palm Beach County residents who make up the marine industry are some of the hardest-working people in our community; continued and necessary maintenance of the IWW facilitates vessel access to marine facilities and helps protect marine industry jobs. The marine industry’s estimated 8,300 marine-related jobs in Palm Beach County comprise one of the largest portions of the estimated industry’s $874 million annual economic revenue to the county.
DESIGN: The federally-authorized navigation channel is 125-ft wide (base width) with 3 (horizontal):1(vertical) side slopes, and a bottom elevation of -10 ft MLLW. The project will also include up to 2-ft of allowable overdepth dredging (Figure 1). Based on a February 2016 bathymetric survey, the project will remove approximately 84,000 cubic yards (cy) over a project area of 67 acres. Placement within the Tarpon Cove Restoration Area will occur at locations identified by Palm Beach County. Placement will occur by barge mounted mechanical equipment.

Material from this project will be use by Palm Beach County's Tarpon Cove project.
