South Atlantic Coastal Study - SACS

SACS South Atlantic Coastal Study map graphic

The South Atlantic Coastal study will be modeled closely after the North Atlantic Coast Comprehensive Study (NACCS), a Congressional response and precedent-setting vulnerability and flood risk-reduction study completed for the North Atlantic coastline in the wake of Hurricane Sandy.  The study will conduct regional analyses of coastal risk and identify initial measures/costs that can address vulnerabilities with emphasis on regional sediment management (RSM) as an actionable strategy to sustainably maintain or enhance current levels of coastal storm risk reduction.

Reducing coastal risk is a responsibility shared by all stakeholders including coastal communities, local and state governments, tribes, Federal agencies, and others throughout the study area which covers over 65,000 miles of tidally influenced shorelines. Locations within the USACE South Atlantic Division area of responsibility that are affected by sea level rise, and where hurricane and storm damages occur or are forecast to occur, are included within the study area.

Study Authority

The South Atlantic Coastal Study was authorized by Section 1204 of WRDA 2016. Guidance was issued on Nov. 16, 2017, requiring the study to follow planning guidance for watershed assessments. Public Law 115-123 provided Federal funding in the amount of $16M to cover 100% of the Study costs.

Study Goals

  1. Provide a Common Operating Picture of Coastal Risk
  • Provide decision-makers at all levels with a comprehensive and consistent regional assessment of coastal risk.
  1. Identify High-Risk Locations/Focus Current and future resources
  • Enable resources to be focused on the most vulnerable areas
  1. Identify and Assess Risk Reduction Actions
  • Assess actions that would reduce risk to vulnerable coastal populations
  1. Promote and Support Resilient Coastal Communities
  • Ensure a sustainable coastal landscape system, considering future sea level rise scenarios and climate change. Provide information to stakeholders to optimize existing efforts to reduce risk.
  1. Promote Sustainable Projects and Programs
  • Develop and provide consistent foundational elements to support coastal studies and projects; Regionally manage projects through Regional Sediment Management and other opportunities.
  1. Leverage Supplemental Actions
  • Multiple Federal supplemental studies and construction efforts funded by Public Law 115-123 will inform, and be informed, by the SACS

South Atlantic Coastal Study - Vision Meeting #1
U.S. Army Corps of Engineers, Jacksonville District
Feb. 27, 2019 | 49:46
The South Atlantic Coastal Study (SACS) is located within the coastal areas of the USACE South Atlantic Division which includes the states Alabama, Florida, Georgia, Mississippi and North Carolina.

The study will identify the risks
and vulnerabilities of those areas to increased hurricane and storm damage as a result of sea level rise, and identify specific and detailed actions to mitigate risks.

SACS will proactively address the coastal storm and flood risks of vulnerable coastal populations, property, ecosystems, economies, and infrastructure along the south Atlantic coastline now and into the future.

The assessment will apply lessons learned from the North Atlantic Coast Comprehensive Study (NACCS), a Congressional response and precedent-setting vulnerability and flood risk-reduction study completed for the north Atlantic coastline in the wake of Hurricane Sandy.
