ATM, a Geosyntec company, provided full-service planning, public outreach, engineering, design, permitting, bidding, and construction administration support on the rehabilitation of 10,000 linear feet of the northern portion of the Jekyll Island oceanfront shoreline. The revetment was built in the late 1960s-1970s as the “Johnson Rocks” following Hurricane Dora and slowly deteriorated over time while sustaining significant damage during the 2016 and 2017 hurricane seasons.
To quickly provide storm protection for critically vulnerable areas, the project was divided into two phases. Phase 1 included maintenance and repair of the revetment, to return the structure cross-section to the original design template. We completed the planning and design and expedited permitting under USACE’s Nationwide Permitting Program. Archeological sites of significance were found in the project area and ATM worked with local, state, federal, and Seminole Nation representatives to quickly resolve project impact issues.
Phase 2 of the project included large scale truck haul terrace beach fill operations from an upland sand source, dune restoration, native vegetation planting, dune crossovers, and geotextile tube installation. ATM provided preliminary design, permitting, and final design and bid support services for Phase 2 with construction concluding in spring 2021.
ATM helped secure millions of dollars in state and federal emergency funding to cover the project costs based on our detailed FEMA engineering damage estimates and project cost projections.
