Chandeleur Islands
The state of Louisiana constructed two sand berms between 2010 and 2011 to protect the Chandeleur Islands as part of an emergency response plan to mitigate the effects of the Deepwater Horizon oil spill. Most of the sediment placed in the berms mimicked nearshore beneficial use of dredged material applications that are used for barrier island nourishment and restoration. A study found that sediment was transported onto existing island features or across the island into Chandeleur Sound. The build up and reinforcement of the island ensures its viability as wildlife habitat, making this an excellent example of working with natural processes to produce beneficial results. The effort to create the berms and evaluate them was a collaboration between multiple state and federal agencies, including the U.S. Army Corps of Engineers.
