The Jekyll Creek team was recently awarded the FY20 USACE Sustainability Green Dream Team Award and will be featured in the upcoming “Engineering With Nature: An Atlas Vol. 2” available on 7 April 2021 at:

The Jekyll Creek Beneficial Use Pilot Project is a collaboration between USACE (RSM Center, Savannah District, Jacksonville District), state and federal agencies, stakeholders, academia, and industry to develop both environmentally and economically sustainable beneficial use of dredged material solutions for maintaining Navigation projects in the State of Georgia and to support coastal resilience throughout SAD.

Through collaboration and the shared vision of the team, USACE and our partners developed and successfully executed two innovative beneficial use placement strategies consistent with RSM principles which are Open Water Dispersal and Thin Layer Placement (TLP).

The strategies were the first to be executed by USACE in SAD and a first for the State of Georgia. These environmentally acceptable and economically efficient strategies provide opportunities for future RSM applications in Georgia and throughout the southeast with potential applications across USACE divisions. Incorporation of these two placement strategies could help the USACE Navigation program take a big step towards the goal 100% beneficial use of dredged material.




The SACS was initiated in 2018 and will identify risks and vulnerabilities to increased hurricane and storm damage as a result of sea level rise, emphasize Regional Sediment Management practices to sustain/enhance current coastal storm risk management measures, recommend measures to address coastal vulnerability of areas affected by SLR, and develop a long-term strategy to address increased hurricane/storm damages resulting from SLR, enhance resiliency, and lower risks. The study will be completed in August 2022 and information about the study and associated products and data is available at: and

SACS includes 12 study products and completed products include the Tier 1 Risk Assessment, 2020 RSM Optimization Update, and Sand Availability and Need Determination (SAND) study. The 2020 RSM Optimization Update and SAND study were RSM-focused products and are highlighted below.


The SAND study quantifies sand needs and available sand resources for all current beach nourishment projects, both federal and non-federal, in SAD for the next 50 years. SACS utilized a stakeholder and consensus building approach to achieve Congressional requirements for SACS. The SAND study exemplifies this collaborative approach by executing the project with 12 federal and state agencies led by technical experts from all five SAD districts and a contracted coastal engineering firm.


Sand needs for all beach nourishment projects and available sand resources (e.g. offshore, RSM, and/or upland sources) were quantified by county. Regionally, a total of 1.3 billion CY of sand are needed to support the 50-year sand needs and 1.5 billion CY of sand resources were identified. While regional sand resources are greater than documented sand needs as of today, economically viable long-term sources are limited in many areas across the region. Sand shortages are documented in numerous counties of every state in SAD and municipalities in Puerto Rico. Further, critical sand shortages were identified across regions of North Carolina, South Carolina, Florida, Alabama, and Mississippi. Considering the SAND study only accounted for permitted or near-permitted projects across SAD, it’s likely that additional projects will be permitted in the coming years, increasing the demand for beach quality sand.

The 2020 RSM Optimization Update builds on the efforts of the 2016 SAD RSM Optimization Pilot which was developed to help identify additional means to streamline existing processes and ensure solutions are increasingly economical and environmentally sustainable across USACE authorities and missions. The 2020 RSM Optimization Update was initiated through SACS to support the identification and continued implementation of sustainable solutions under current authorities.

The Update analyzed over 70 USACE Navigation and Coastal Storm Risk Management projects in SAD and includes fact sheets for each project that include placement strategies, volumes, frequencies, cost, and future opportunities. The report highlights beneficial use strategies implemented across SAD including beach placement, nearshore placement, thin layer placement (TLP), open water dispersal, and habitat creation.

The Charleston District has numerous active RSM initiatives in progress and on the horizon at Charleston Harbor, Folly River, and Folly Beach. Offshore artificial reefs (see imagery below), berms around the Ocean Dredged Material Disposal Site (ODMDS) to support fish habitat and sediment containment, restoration of Crab Bank, and beach placement of sand at Morris Island to support the south jetty terminus are all in the works at Charleston Harbor.



The Folly River Entrance Channel is scheduled to be dredged in spring/summer of 2021 and approximately 60,000 cubic yards of sand will be placed in the nearshore at Folly Beach. To evaluate the effectiveness of the placement strategy, the district is supporting a 2-year sediment tracer study and Argus camera system deployment. Nearshore placement is a RSM strategy to reduce storm damage impacts and increase coastal resilience. 


The Jacksonville District is in the process of offloading approximately 140,000 cubic yards from the Manatee Harbor Dredge Material Management Area (DMMA) to Washington Park (see image to left), owned by Manatee County (FL).  Dredged material capacity at Manatee Harbor was nearly exhausted and the project provides capacity for future dredging events to support for future maintenance dredging. 


Using the offloaded dredged material as fill, the County has a master plan to convert the Washington Park borrow pit into an environmental preserve aiming to mimic the historical ratio of wetland and upland habitats. The beneficial use offloading strategy supports long-term maintenance of the Manatee Harbor Channel and provides social and environmental benefits for Manatee County. For additional information about how the project is fits into Manatee County’s plan for Washington Park, visit


The Mobile District recently completed the construction of the Mississippi Coastal Improvements Comprehensive Barrier Island Restoration project with the placement of over 22 million cubic yards of sediment to restore the system.  The project was recently highlighted in a podcast “Engineering with Nature”, exploring how infrastructure will play a role in worldwide recovery as they highlight success in coastal collaboration and will also be featured in the upcoming “Engineering With Nature: An Atlas Vol. 2” available on 7 April 2021 at:

The Mississippi Coastal Improvements Comprehensive Barrier Island Restoration project is a testiment to the collaboration between USACE,  state and federal agencies, stakeholders, academia, and industry to develop a triple win that provides environmental, economic and social benefits; integrating in regional sediment management practices and engineering with nature techniques.
