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.

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.

Measures & Costs Library

Detailed list of CSRM measures and their costs developed to a screening level for use in USACE and stakeholder planning

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.

Planning Aid Report

Report of priority biological resource habitats in the South Atlantic region that are vulnerable to harm from coastal storms and sea level rise with a focus on areas used by federally-listed species. Report will also include a description of risk to coastal National Wildlife Refuges

Planning Aid Report

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.

Environmental and Cultural Resources Workshops
Workshops were recently held to present the environmental and cultural resources at risk to increased coastal storm damages. A recording of the Environmental Workshop on Priority Environmental Areas is available in the video playlist. Slides from the previous workshops on environmental and cultural resources are available under Presentations

Shared Vision

"The SACS vision is to provide a common understanding of risk from coastal storms and sea level rise to support resilient communities and habitats.  This collaborative effort will leverage stakeholders' actions to plan and implement cohesive coastal storm risk management strategies along the South Atlantic and Gulf Coast shorelines, including the territories of Puerto Rico and the U.S. Virgin Islands."
