BACKGROUND/RELATED STRATEGIC GOAL:
Bathtub Beach and the adjacent Sailfish Point beaches have faced chronic erosion issues since the late 1990s, escalating significantly in fall 2007. Repeated dune breaches threatened MacArthur Boulevard and infrastructure, prompting emergency sand replenishment projects. Prior to 2016's engineered solutions, the dune served as a natural barrier, protecting MacArthur Boulevard, and experienced natural erosion to a stable limit along the shoreline.
Bathtub Beach and Sailfish Point beaches are a unique system, bound by an eastern reef hindering natural sand movement onshore and offshore and a southern inlet/jetty blocking northward sand movement. This necessitates a holistic, system-wide approach to beach management. This systematic approach is addressed by the State of Florida mandated St. Lucie Inlet Management Plan which facilitates sand bypass distribution from the inlet, impoundment basin, and navigation channels to replenish beaches north to Bathtub Beach and south on Jupiter Island.
Other management strategies include the first engineered beach project which was originally was built in 2016, stretching for about a mile north of Bathtub Reef Beach Park and extending south to Sailfish Point. This cyclic project replenishes sand every three to five years to continuously combat erosion. In 2019, a long-term agreement was established between the County, Sailfish Point Property Owners and Country Club Association (SPPOA), to share the costs of the Sailfish Point/Bathtub Beach Restoration Project after grant funding was secured. Most recently, in 2023, the County utilized a Federal Emergency Management Agency (FEMA) grant to construct a seawall buried beneath the dune at Bathtub Reef Beach. This seawall aims to prevent future emergency sand hauling responses during hurricane season or high intensity coastal storm events.
The presentation will be added via a Supplemental Memorandum.
