PROJECT STATUS REPORT as of 19-Aug-2019

Pass-a-Loutre Crevasse DEAUTHORIZED

PROJECT LOCATION:

PROJECT DESCRIPTION:

The area north of Pass a Loutre and east of the Mississippi River no longer receives marsh-nourishing sediment from the river due to the enhancement of the bank line. The hopper dredge disposal material that is routinely placed into this pass is retained in the channel bed usually until the low water season, at which time it is scoured away and carried out to the mouth of Pass a Loutre. A crevasse will allow the sediments to enter near the mouth of the pass and be deposited in the shallow open water area between Pass a Loutre and Raphael Pass to create new emergent marsh. As a direct result of construction, about 80 acres of shallow open water bottom will be converted to prime fresh marsh, and another 80 acres would be gained when the excavation is repeated after 10 years. However, over the 20-year life of the project, the crevasse will create about 1,000 acres of emergent marsh.

PROJECT STATUS: (Project Status Last Updated: 1-Jan-1990 )

Two pipelines and two power poles are in the area of the crevasse, increasing relocation costs by approximately $2.15 million. LA DNR asked that the Corps investigate alternative locations to avoid or minimize impacts to the pipelines, but there are no more suitable locations for the cut. The Corps has also reviewed the design to determine whether relocations cost-savings could be achieved. Reducing the bottom width of the crevasse from 430 feet as originally proposed to 200 feet reduced the relocation cost only marginally.

A draft memorandum dated December 5, 1997 was sent to the CWPPRA Technical Committee Chairman requesting the Task Force to deauthorize the project. COE requested deauthorization at the January 16, 1998 Task Force meeting. Task Force formally deauthorized project July 23, 1998.

FUND STATUS:

The current project estimate is $119,835 , which includes $108,114 for construction first costs, and $11,721 and $0 for 20 years of monitoring and operations and maintenance, respectively.
