PRESENTATION: Rockefeller Refuge Gulf Shoreline Stabilization
DESCRIPTION: Rockefeller Wildlife Refuge in southwest Louisiana is managed by the Louisiana Department of Wildlife and Fisheries to provide refuge for wildlife and fisheries, opportunity for in the field research, and public education, outreach, and outdoor recreation. Erosion is claiming approximately 50 feet of Gulf shoreline along the Refuge each year. This is the equivalent loss of about 40 acres per year. The Louisiana Coastal Protection and Restoration Authority (CPRA) teamed with the National Marine Fisheries Service (NMFS) through the Coastal Wetlands Planning, Protection and Restoration Act (CWPPRA) program to combat erosion at the Refuge. Due to the very soft clay soils along the shoreline and lack of sand in the littoral system it became apparent that conventional stone breakwaters and beach nourishment techniques would not be appropriate. Considering the wave field, soil bearing capacity, project budget, and protection criteria, several options were subsequently identified that could provide the needed protection. These options included a reef breakwater, reef breakwater with lightweight aggregate core, and gravel beach fill. These options were constructed as part of a $7 million demonstration project prior to implementation of the full project. The options constructed for the demonstration phase were monitored for one year. Data collected during the monitoring of the demonstration project was utilized to select the preferred alternative for implementation along the project shoreline. Based on available funding, approximately 4 miles of breakwater was constructed through the CWPPRA program. Additional funding sources are currently being assessed to continuing constructing the breakwater along the remaining project length.
