Jekyll Island Oceanfront Shoreline Rehabilitation, Jekyll Island, Georgia
« All Projects

Project Objective

Geosyntec 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 through 1970s as the “Johnson Rocks” following Hurricane Dora and slowly deteriorated over time while sustaining significant damage during the 2016 and 2017 hurricane seasons.

Scope of Services

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 Geosyntec practitioners 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 from an upland sand source, dune restoration, native vegetation planting, dune crossovers, and geotextile tube installation. Geosyntec provided preliminary design, permitting, and final design and bid support for Phase 2 with construction concluding in spring 2021.

Notable Accomplishments

Geosyntec helped secure a significant amount of state and federal emergency funding to cover the project costs based on our detailed FEMA engineering damage estimates and project cost projections.

Note: At the time of this project, Geosyntec practitioners were contracted as ATM, which was acquired by Geosyntec.
