This Request for Information (RFI) seeks industry input for rehabilitating the seaward 400 feet of the St. Lucie South Jetty in Martin County, Florida. The jetty, constructed between 1978-1982, has deteriorated significantly due to asphalt and grout degradation, armor stone instability, and slope instability, particularly at its head section. This degradation threatens the inlet's stability and Jupiter Island's northern end, potentially increasing federal project maintenance costs. The project aims to repair and rehabilitate the most damaged section by restabilizing the foundation and adding a second layer of armor stone, incorporating future sea-level rise and storm severity. The RFI asks specific questions regarding equipment transport, rehabilitation methods, feasibility concerns, land vs. water-based work, access road improvements, staging area needs, health and safety concerns, winter construction protections, runoff management, estimated duration, and procurement lead times. Responses are due by January 2, 2026, with an industry conference call on January 6, 2026.

This government file details the proposed South Jetty rehabilitation project at St. Lucie Inlet, Martin County, FL, undertaken by the US Army Corps of Engineers. The project involves significant structural improvements, including excavation, marine mattress placement, and armor stone rework and placement. Key elements include foundation excavation to varying depths, the extension of marine mattresses, and the use of specific armor stone sizes (W50 = 8 tons and 11 tons) to enhance structural integrity and protection. The document provides detailed overviews of the existing conditions, proposed layouts for excavation and stone placement, and typical cross-sections for the West Head, East Head, and fishing platforms. Survey data from March and April 2023 by Survtech Solutions informed the design. The project aims to restore and fortify the jetty, ensuring the continued navigability of the St. Lucie Inlet Federal Navigation Channel.
