South Atlantic Coastal Study - SACS

Technical Study Products

There will be a total of 12 study products in this study. Information on each technical product will be provided here when available.

Regional Sediment Management (RSM) Optimization Update


RSM Update 
The 2020 South Atlantic Division (SAD) Regional Sediment Management (RSM) Optimization Update builds on the efforts of the 2016 SAD RSM Optimization Pilot (OP) which was developed to help identify additional means to streamline existing processes and ensure solutions are increasingly economical and environmentally sustainable across U.S. Army Corps of Engineers (USACE) authorities and missions.

Sand Availability and Needs Determination (SAND)


SAND Report
The Sand Availability and Needs Determination (SAND) study quantifies sand needs and available sand resources for all current beach nourishment projects, both federal and non-federal, in the South Atlantic Division (SAD) of the U.S. Army Corps of Engineers (USACE) for the next 50 years.

Focus Area Action Strategies (FAAS)


FAAS will use SACS products in combination with other resources to develop actionable risk reduction strategies with stakeholders. FAAS will serve as examples of how vulnerabilities in other high risk locations can be addressed.

Study Overview

The 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.
