Section 1204 of WRDA 2016 authorizes the Secretary to conduct a comprehensive coastal study within the geographic boundaries of the South Atlantic Division (SAD) to identify the risks and vulnerabilities of those areas to increased hurricane and storm damage as a result of sea level rise; recommend measures to address the vulnerabilities; develop a long-term strategy addressing increased hurricane and storm damages that result from rising sea levels; and identify opportunities to enhance resiliency, increase sustainability, and lower risks in populated areas, areas of concentrated economic development, and areas with vulnerable environmental resources. The South Atlantic Coastal Study (SACS) is a response to this authorization. The study area includes the tidally-influenced coastal areas of Alabama, Florida, Georgia, Mississippi, North Carolina, Puerto Rico and the U.S. Virgin Islands. In addition to regional analyses of coastal vulnerability, the SACS will identify initial measures/costs that can address vulnerabilities with emphasis on regional sediment management as an actionable strategy to sustainably maintain or enhance current levels of storm protection.


a. P.L. 115-123: Bi-Partisan Budget Act of 2018, Supplemental:

Current Working Estimate $16,000,000
Allocation thru FY18 $300,000
Allocation for FY19 $6,200,000




The SACS was initiated in August 2018 by a regional Project Delivery Team comprising members from all five districts across the USACE South Atlantic Division. The team has drafted a ‘Tier 1’ regional risk assessment and is in the process of validating that risk assessment with the districts for rollout and feedback from stakeholders across the region. Project Performance Evaluations for all coastal storm risk projects within SAD have been completed, and a desktop analysis of regional sand resources will begin shortly. The US Army Engineer Research and Development Center (ERDC) is underway with the development of a Coastal Hazard System database to be used in refining hazards associated with wave and water elevations by both federal and non-federal partners. Vision Meeting 1 (held Feb 2019) kicked off an extensive Outreach program that will engage all interested stakeholders and non-federal partners in the development of study conclusions. Development of risk reduction measures and associated parametric costs are also in-progress.  All SAD districts have begun coordination on their respective State Appendices.
