LCA Critical Nerm-Term Restoration Projects

The 15 critical, near-term restoration projects identified in the Louisiana Coastal Area program are intended to provide relief from coastal landloss and supplement large-scale, long-term restoration programs and studies that will restore natural features and ecosystem processes.  Several restoration techniques are employed in these projects, including river diversions, marsh creation and barrier island restoration.

Small Diversion at Hope Canal
