| Abstract: | This technical report provides a description of Regional Sediment Management (RSM) investigations performed by the U.S. Army Corps of Engineers, Jacksonville District, along Florida’s northeast coast in Nassau and Duval Counties. Provided first is an overview of the study area, including previous RSM activities, pertinent studies, and stakeholder discussions. Next is a discussion of the various Federal projects in the study area, including authorization, funding, and permitting. Finally, management alternative strategies are provided for each project, as well as recommendations for future actions to improve management of the sediments. The most successful implementation of RSM principles in northeast Florida involves beneficial use of navigation maintenance sediment to serve as shore protection and mitigation for navigation projects’ disruption to the natural sediment transport patterns and morphology. The beneficial use of dredged sediment from the Mayport Navy project and the Jacksonville Harbor Federal Navigation project has been successful to date but could be expanded through the use of nearshore placement. Additional opportunities outlined in this report that would enhance the RSM program in northeast Florida are currently under investigation or need further investigation. A more robust data collection program is needed to develop a greater understanding of the physical processes that influence sediment transport in the vicinity of northeast Florida Federal projects. Geotechnical investigations are required to ensure sediment compatibility between areas of identified sources and areas of need, including delineation of borrow areas. The multitude of stakeholders that have an interest in the coastal system within the northeast Florida area requires that management strategies and alternatives are actively coordinated. |
