Purpose: This document summarizes the management approach for the Dredged Material Confinement Areas (DMCAs) (located in Jasper County, SCa) at the Savannah Harbor Navigation Project (SHNP) in the Savannah Harbor, Chatham County, GA. The management approach is detailed in the U.S. Army Corps of Engineers (USACE) Savannah District, Long Term Management Strategy (LTMS) (USACE 1996). The LTMS was initiated to mitigate wetland losses in Georgia and South Carolina from ongoing dredged material deposition, harbor deepening efforts, and normal operating activities from maintenance of the Savannah Harbor. Since the inception and implementation of the LTMS in 1996, USACE has recognized that engineering operations, particularly those that involve dredged material deposition, can provide opportunities for infrastructure enhancement by applying improved engineering practices, and by incorporating natural features in the final product, which yield additional environmental benefits. The Engineering With Nature® (EWN) initiative incorporates both infrastructure development and enhancement with environmental management (Banks et al. 2013, USACE 2013, Bridges et al. 2018). Many of the design and management features of the SHNP and implementation of the LTMS on the DCMAs have incorporated principles of EWN. The purpose of this technical note is to: (1) summarize the creation and management of the DMCAs from implementation of the LTMS, (2) identify and describe features of the LTMS in common with EWN principles, and (3) discuss how this approach improves USACE’s ability to meet mission objectives while providing environmental benefits to the local and regional ecosystem.
