BACKGROUND/RELATED STRATEGIC GOAL:
The Florida Department of Environmental Protection (FDEP) requires that the responsible entity for each inlet in Florida be guided by an Inlet Management Plan. Inlets along the coast divert sand that would otherwise be propelled by the currents along the beach, traveling in the nearshore area. On the east coast of Florida, the primary currents run from north to south, often driven by strong nor'easter storms. As the sand that is being propelled by the currents hits the improved inlets, some of the sand is redirected, reducing the volume of sand that makes its way to the beach on the south side of the inlet. This scenario also plays out in reverse, with a much milder current periodically running south to north, and a smaller volume of sand is lost to beaches to the north when it reaches the inlet.
An updated management plan for the St. Lucie Inlet (SLIMP) was adopted by the FDEP in January 2016. The plan identifies the average annual sand placement required on beaches north and south of the inlet to mitigate for erosion impacts caused by the St. Lucie Inlet. Martin County has complied with the required sand placement north of the Inlet with beach construction projects on Bathtub Beach and Sailfish Point beach. The SLIM...
