Archeological and Historical Investigations of Four Proposed Revetment Areas Located Along the Mississippi River in Southeast Louisiana
Abstract
This report presents the results of archeological and historical research conducted on four proposed revetment areas located along the Mississippi River in southeast Louisiana. The research was carried out by Coastal Environments, Inc. (CEI) under contract to the U.S. Army Corps of Engineers, New Orleans District. The northernmost revetment area, Arrow Bend, consisted of two segments located along the left descending bank of the river in West Feliciana Parish. The second revetment area, Manchac, was located on the left descending bank in East Baton Rouge Parish. The third and fourth areas, Marchand and Aben, were situated on the left descending bank and the right descending bank, respectively, in Ascension Parish. Construction of the revetments will involve clearing and grading the bankline to a stable slope and then laying an articulated concrete mattress from the low water line into the river channel. This may impact an area 200 to 300 ft (61.0 to 91.4 m) back from the water's edge and as much as 10 ft (3.0 m) below the surface. In addition, the ground surface beyond 300 ft from the bankline may be disturbed by movement of heavy equipment. The total area examined by the present surveys was 303.9 ac (123.1 ha).
