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.

Regional Sediment Management (RSM) Optimization 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)

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

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.

Study Goals

Click here to expand
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.
2. Identify High-Risk Locations and Focus Current and Future Resources
- Enable resources to be focused on the most vulnerable areas.
3. Identify and Assess Risk Reduction Actions
- Assess actions that would reduce risk to vulnerable coastal populations.
4. 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.
5. 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.
6. Leverage Supplemental Actions
- Multiple supplemental studies and construction efforts will inform, and be informed by, the SACS.

Authority

Section 1204, WRDA 2016
- Identify risks and vulnerabilities of [coastal areas within SAD AOR] to increased hurricane and storm damage as a result of sea level rise (SLR).
- (b)(1) Conduct a comprehensive analysis of current coastal storm risk management measures with an emphasis on regional sediment management practices to sustain/enhance current storm protection.
- (b)(3) Recommend measures to address coastal vulnerability of areas affected by SLR.
- (b)(4) Develop a long-term strategy to address increased hurricane/storm damages resulting from SLR and identify opportunities to enhance resiliency and lower risks in –
  - populated areas
  - areas of concentrated economic development; and
  - areas with vulnerable environmental resources
- (c) Submit a report recommending specific and detailed actions

Statement of Study Area

Click here to expand
Over 65,000 miles of tidally influenced coastline in the South Atlantic Division area of responsibility affected by sea level rise (SLR) where hurricane and storm damages are occurring, or are forecast to occur.
- Areas that are not subject to hurricane and storm damage associated with coastal processes are outside the scope of the study (i.e., areas subject to inland/freshwater flooding).

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."
