LA 16 NON-ROCK ALTERNATIVES TO SHORELINE PROTECTION DEMONSTRATION PROJECT
IBERVILLE, JEFFERSON, AND LAFOURCHE PARISHES, LOUISIANA
Several shoreline areas within coastal Louisiana consist of unstable soil conditions, subsurface obstructions, and accessibility problems which severely limit the alternatives of shoreline protection. The purpose of this project, developed under the Coastal Wetlands Planning, Protection, and Restoration Act, is to demonstrate the use of alternative shoreline protection products and methods in environments where rock revetments or foreshore installations may not be advantageous. Under this project, five products will be installed parallel to the shoreline at three sites in coastal Louisiana. Gaea oversaw the design for one of the demonstration products, which included determining the mean high water elevation and wave conditions, designing the product installation, and producing construction plans, specifications, and cost estimates for each site. The product consists of stacked concrete units installed on piles.
