LA TIG Phase 2 Restoration Plan/Environmental Assessment #7.1: Terrebonne HNC Island Restoration Project

This Final Phase 2 Plan evaluated a reasonable range of design alternatives and selects alternative 7A as the preferred design for construction.  The project will restore and conserve bird nesting and foraging habitat and create, restore, and enhance barrier and coastal islands and headlands by increasing the acreage of the island from 27.6 acres up to approximately 45 acres of shrub nesting, ground nesting, and marsh habitat. An existing, degraded perimeter rock dike will be restored, and breakwaters may be constructed on the northeast side of the island to provide further protection as well as calm water for loafing birds. Habitat restoration will be accomplished by raising the elevation of HNC Island using dredged material from a borrow area near Cat Island Pass.
