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.

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

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.

March/April Newsletter Available

Coastal Hazard System Now Available
The Coastal Hazards System (CHS) is a coastal storm hazards data storage and mining system and is now available. It stores comprehensive, high-fidelity, numerical modeling storm-responses such as storm surge, water level, wave height, wave period, wave direction and current magnitude.  Please click here for more information.

Request for Photos
We are looking for photos to include within the SACS report. Photos should capture the focus of SACS which is to provide a common understanding of risk from coastal storms and sea level rise to support resilient communities and habitats.  We specifically are interested in photos that depict: property, assets, infrastructure, environmental resources and cultural resources in ocean-front, back bay and tidally influenced riverine settings during storm events or during non-storm events.  If you have photos that you or your agency/association/associated group has rights to publish or that are public domain, please email SACS@usace.army.mil for further coordination.

Quarterly Progress Briefing
The most recent SACS quarterly progress briefing was held on April 22nd and covered the Environmental Resources Vulnerability and Risk Analysis, Priority Environmental Area Identification, and Environmental Analysis StoryMap. Slides from the presentation can be found here and a recording is available in the video playlist.

Geoportal
The SACS Geoportal is now live and available to explore here. Various SACS created datasets and web mapping applications are available for viewing.
