Deepwater Horizon Barrier Island Project Builds on Pre-Spill Restoration Efforts

Restoration efforts in the Barataria Barrier Island complex in Louisiana.

April 24, 2015

This year, NOAA will break ground on the restoration of Chenier Ronquille Island, which is one of the islands in the Barataria Basin in Louisiana. The project is a component of the $318.4 million Louisiana Outer Coast Restoration Project, which includes Shell Island, North Breton Island, and Caillou Lake Headlands. These islands were oiled during the Deepwater Horizon spill.

Restoring Chenier Ronquille will create approximately 500 acres of barrier island habitat, including beaches, dunes, and back-barrier marsh. This new habitat will bolster the Gulf’s environmental recovery from the effects of the spill.

Barrier islands are the first line of defense during storms that threaten coastal communities, as they are very important for reducing the devastating effects of wind and waves and for absorbing storm energy. They also serve as habitat for important fish such as red drum, as well as birds, sea turtles, and other wildlife.

NOAA’s support for this project builds on the agency’s 15-year record of restoring barrier islands off the Louisiana coast. With funding from the Coastal Wetlands Planning, Protection, and Restoration Act, NOAA began work in Barataria Basin in 2006. That nearly-$70 million project included reconstruction of the Chaland Headlands and Pelican Island.

With the restoration of Chenier Ronquille and Shell Island, NOAA and our partners will have undertaken restoration on nearly all of the barrier islands in Barataria Basin.
