About this file
These documents are engineering design drawings for the South Jetty rehabilitation project at St. Lucie Inlet in Martin County, Florida, prepared by the US Army Corps of Engineers. The project involves comprehensive jetty reconstruction, including excavation, marine mattress installation, and armor stone placement. Key technical specifications include: foundation excavation to depths ranging from -1' to -15' NAVD88, marine mattress extensions, armor stone placement with stones weighing 11 tons and approximately 5.88 feet in diameter, and a proposed jetty crest elevation of 11 feet. The rehabilitation focuses on the west and east heads of the jetty, with specific foundation preparation and stone placement strategies to enhance structural integrity. The project site is located adjacent to the St. Lucie Inlet Preserve State Park on Jupiter Island, with the jetty positioned near a federal navigation channel.
