Report release pending

The final NACCS report will be released on or about Jan. 28, pending Congressional approval. Please check back at a later time or, if you believe the report has been released, try refreshing your browser. For questions, contact Justin Ward at 347-370-4550. Thank you.

North Atlantic Coast Comprehensive Study

The goals of the Comprehensive Study are to:
1) Provide risk reduction strategies—reduce risk to which vulnerable coastal populations are subject
2) Promote coastal resilient communities—ensure a sustainable and robust coastal landscape system—considering future sea level rise and climate change scenarios—to reduce risk to vulnerable population, property, ecosystems, and infrastructure.

The $19.5 million Comprehensive Study is due to congress in January 2015. The final study will include a coastal framework as well as storm suite modeling, coastal GIS analysis, and related evaluations, for the affected coastlines. The study will identify existing nature-based infrastructure, include an evaluation of the performance of nature-based infrastructure during Hurricane Sandy and other recent storms, and consider the performance of nature-based infrastructure in reducing the impacts of coastal storm flooding, as well as other impacts at a larger scale and as a system.

Comprehensive Study Background

The congressional response to the devastation in the wake of Hurricane Sandy represents a need to address as a regional system the vulnerability of populations at risk in coastal regions within the boundaries of the U.S. Army Corps of Engineers' North Atlantic Division.

Along with a recent increase in high-magnitude storm events such as Hurricanes Katrina and Rita in 2005, recent storms with larger areal extents creating larger damage areas as evident by the size of Hurricane Irene in 2011 and Hurricane Sandy in 2012, and sea level rise as a probable future condition, there is a need to comprehensively evaluate the existing and planned measures to reduce the flooding risk from tidally influenced storm surges as well as other alternatives for areas at risk to future storm damages.
