The Louisiana Coastal Wetlands Conservation and Restoration Task Force is initiating procedures to deauthorize the Coastal Wetlands Planning, Protection, and Restoration Act (CWPPRA) Avoca Island Diversion and Land Building (TE-49) project as requested by the local project sponsor, the Coastal Protection and Restoration Authority (CPRA), based on questionable constructability given the substrate in the proposed marsh creation area, lack of progress over several years toward project development and implementation, and an unfavorable benefit to cost ratio.
This 12th Priority Project List project was supposed to be located in the Avoca Island area in St. Mary Parish, Louisiana. The objective of the project was to rebuild eroded wetlands in the area through the diversion of fresh water, sediment, and nutrients into an area that is currently shallow open water. Project features under consideration were installation of a diversion structure through the Avoca levee to allow water from Bayou Shaffer to enter Avoca Lake, utilizing a natural bayou as the primary outfall channel west of the levee, plus possible inclusion of dedicated dredging within Bayou Shaffer to obtain materials to create wetlands near the diversion outfall area within Avoca Lake.
Prior to making a final decision, the Task Force will consider written comments on the request to deauthorize the project. Written comments should be provided by April 30, 2013 to the following address:
