Island Road Marsh Creation & Nourishment

State/Territory:

This project will restore 295 acres of tidal marsh that had severely degraded from erosion, subsidence, storms, and canal and pipeline construction. Marsh restoration will reduce risks from storms and sea-level rise, and improve the coastal resiliency of communities in the Parish. The goals of this project are to rebuild the structural framework of degraded marsh and restore resilient habitat by marsh creation and nourishment. Sediment from Lake Tambour will be placed in the restoration area, and dikes will be gapped to allow for dewatering. This, combined with native plantings, will allow the marsh to recover and become critical habitat for many species.
