The 2025 Florida Department of Environmental Protection report warned erosion threatens roads, buildings, drainage systems, natural habitats, wildlife and ancient sites on Jupiter Island. The threat stretches from Blowing Rocks Preserve to Peck Lake, where a breach could turn a thin strip of land into an open inlet. A storm breached Peck Lake in the early 1960s before the U.S. Army Corps of Engineers filled it back in with sand.
Jupiter Island Commissioner Marshall Field said the town continues to fight erosion through constant maintenance. In April 2025, the town completed a major beach renourishment project, dumping enough sand to fill nearly 400 Olympic-sized swimming pools. Field said about $3 million in town taxpayer dollars goes toward beach renourishment every year. He said no oceanfront homes are in immediate danger but only because of ongoing work.
Mark Perry with the Florida Oceanographic Society said the consequences extend well beyond the shoreline. The Joseph Reed Mound, a 3,000- to 4,000-year-old archaeological site, is already half lost to erosion, according to the report. Wildlife refuges including Blowing Rocks Preserve, Hobe Sound Wildlife Refuge and St Lucie Inlet Preserve State Park are also at risk. Perry said over 33 threatened and endangered species inhabit those areas.
