Project Description

This project will partially supplement the natural sediment budget for the Perdido Key Unit of Gulf Islands National Seashore by placing at least 400,000 cubic yards of sediment dredged from Pensacola Pass onto the easternmost two miles of Perdido Key. The National Park Service (NPS) will work in close coordination with U.S. Army Corps of Engineers (USACE) to do so. Specifically, the project will: - Re-introduce sand into the barrier-island system using a pipeline from the dredging location. The exact placement location will depend on the condition of the shoreline at the time the dredging occurs. - Complete a National Historic Preservation Act (NHPA) Section 106 survey for the entire seven-mile southern shoreline of the Perdido Key Unit to support future sediment placement projects. The goals of the project are to improve wildlife and plant habitat at Perdido Key and improve the ability of Perdido Key to withstand the natural erosive effects of storms. A historical sediment deficit exists in the system due to recurring maintenance dredging of the lower harbor federal navigation channel. This dredging, with offshore deposition of the sediment, has interrupted the natural westward littoral drift of sand, leading to unnaturally narrow beaches and diminished habitat, storm protection, and recreational opportunities on Perdido Key. Project activities include planning/design, implementation, and monitoring. If project activities are coordinated with USACE or Navy operations and maintenance dredging in Pensacola Pass or Bay, then dredging activities will be partially funded by those agencies and the project will require on "More Info" link below
