Abstract: Lake Worth Inlet connects Palm Beach Harbor to the Atlantic Ocean. The port is located in Riviera Beach, Palm Beach County, Florida. Lake Worth Inlet, serving as the entrance channel to the port, is inadequate both in width and depth, negatively impacting future port potential and creating economic inefficiencies with the current fleet of vessels. Based on existing vessel sizes, the port is operating with insufficient channel width and depth. These deficiencies cause the local harbor pilots in conjunction with the U.S. Coast Guard to place restrictions on vessel transit to ensure safety resulting in economic inefficiencies translating into costs to the national economy. The recommended plan proposes the following (Refer to Figure ES‐4 for a graphic depiction of the recommended plan and refer to the foldout at the end of the report showing existing and recommended plans): deepen the entrance channel from 35 feet to 41 feet and widen from 400 feet to between 440‐460 feet plus a southern approach flare; deepen the inner channel from 33 feet to 39 feet and widen from 300 feet to 450 feet; deepen the main turning basin from 33 feet to 39 feet and extend the southern boundary of the turning basin an additional 150 feet. Suitable sand would be placed in the nearshore. Some material would be beneficially used for proposed mitigation; unsuitable material would be taken to the Palm Beach Ocean Dredged Material Disposal Site. Approximately 4.5 acres of seagrass habitat and 4.9 acres of hardbottom habitat would be affected through implementation of the recommended plan. In addition, immediately south of the main turning basin, a warm water outfall from the Florida Power and Light Riviera Plant creates a warm water refugium for manatees during cold periods.
