Project Location
This project is located in Vermilion Parish in southwest Louisiana. The project addresses critical areas along the eastern bank of the Freshwater Bayou Navigation Canal, starting just north of the intersection of Humble Canal and the Freshwater Bayou Navigation Canal.
Project Description
This project utilized $1.3 million in surplus funding from the completed Marsh Creation Near Freshwater Bayou (ME-0025 SF) project to augment the foreshore rock dike feature along Freshwater Bayou in Vermilion Parish constructed as part of the CIAP Freshwater Bayou Bank Stabilization (TV-0011-B [EB]) project.
Issue Addressed
In 2014, the CIAP Freshwater Bayou Bank Stabilization Project TV-11b(EB) constructed approximately 33,000- linear feet of foreshore rock dike in five reaches (Southwest Reach 12 - 541 L.F., Southeast Reach #2 - 3,936 L.F., Northeast Reach- 7,222 L.F., Northwest Reach #1- 7,498 L.F., Northwest Reach #2- 1,777 L.F.). The pre-construction surveys showed a change in the elevation of the channel relative to the design survey included in the plans where the foreshore rock dike was to be constructed, resulting in increased stone quantity required to construct the foreshore rock dike to the target elevation. As a result of the required increased quantities due to differing site conditions, the CIAP Freshwater Bayou Bank Stabilization Project (TV-11b(EB) was only able to construct 60% of Southeast Reach #2 (3,936 L.F. of the required 6,217 L.F.) and unable to construct any of Southeast Reach # 1(927 L.F.).
Project Goals
This Project involves constructing approximately 3,200 linear feet of foreshore rock dike along the east bank of the Freshwater Bayou Canal in order to reduce bank erosion from vessel wakes and minimize saltwater intrusion into the deteriorated marsh adjacent to the Freshwater Bayou Canal.
