COASTAL RESTORATION

Aucoin & Associates, Inc. has been involved in several efforts to restore Louisiana’s eroding coastline with state and federal agencies.  The Pecan Island Terrace Creation is an effective project which is designed to trap sediment and ultimately recreate valuable marshland.  Approximately 197,000 linear feet of earthen terraces were constructed in a pattern to maximize the trapping of sediment.  

In addition to design, Aucoin & Associates, Inc. has provided construction oversight and layout surveying services for numerous terracing projects throughout coastal Louisiana.  We are dedicated to protecting our coastal areas for our future generations.

PECAN ISLAND TERRACE CREATION

Completed August 2003

 SYNOPSIS

Pecan Island Terrace Creation was a Louisiana Department of Natural Resources project awarded to Aucoin & Associates, Inc. to create new vegetated marsh in the present shallow open water lake.  The scope of the project was to construct earthen terraces in a pattern conducive to reducing wave energy which would enhance propagation of submerged aquatic vegetation.  The project is located in Vermilion Parish and comprises approximately 3,550 acres and consists of primary open water and former pasture land of approximately 1,950 acres and approximately 1,600 acres of brackish marsh and open water.

 The terraces were constructed of in-place dredged soil deposited in berms.  Smooth cordgrass was planted along the water’s edge of the terraces to stabilize the earthen berm and provide habitat for aquatic life.
