Project Overview

ATM was selected to provide engineering, design, permitting, and construction phase services to Jekyll Island – State Park Authority (JIA) for rehabilitation of nearly two miles of oceanfront rock revetment along the northeast portion of the Jekyll Island Shoreline. The revetment was built in the late 1960s-1970s as the “Johnson Rocks” following Hurricane Dora, but has slowly deteriorated over time and sustained significant damage during the 2016 and 2017 hurricane seasons. ATM was hired as the coastal engineering consultant and tasked with:

  1. Initial planning of the project, including public and stakeholder outreach
  2. Design for rehabilitation of the revetment
  3. State and federal permitting
  4. Project bidding and construction phase support

The ATM team worked closely with Jones Hooks – JIA Executive Director and Ben Carswell – JIA Director of Conservation, who worked diligently to bring this project to fruition, as well as the GA Dept. of Natural Resources Coastal Resources Division and USACE Savannah’s District office.

Additionally, 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. Together with JIA, we were able to significantly expedite the permitting process for the large-scale Phase 1 project under the USACE Nationwide Permitting program, including working together with the Seminole Nation of Oklahoma to protect a recently discovered archeologic site adjacent to the project area.

Construction on the Phase 1 Revetment Rehabilitation commenced in late June and is targeted for completion by the end of 2018.

Design and permitting of Phase 2 of the project has also begun and will include a significant sand placement and revegetation effort to help restore the eroded uplands and dune systems landward of the revetment that have deteriorated over the years. Fronted by the rehabilitated revetment that is currently under construction, the completed project will restore and create resilient natural habitat, create beachfront recreational areas, and protect critical infrastructure and properties.
