Channel Armor Gap Crevasse

PROJECT LOCATION:

PROJECT DESCRIPTION:

The project will utilize available sediment in areas which are currently shallow open water bottoms and create emergent marsh. The project will consist of deepening the invert of the existing 150 foot wide gap in the Mississippi River channel bank armor. The existing invert will be lowered to -4.0 feet NGVD. In addition, an existing earthen channel leading from the armored gap to the open water area beyond the bank will be enlarged. Approximately 125,000 cubic yards of material will be excavated from the outfall channel and cast adjacent to the channel in a manner conducive to marsh nourishment. The result will be the conversion of an area of 60 percent open water to an area of approximately 90 percent emergent wetland.

PROJECT STATUS: (Project Status Last Updated: 17-Jun-2002 )

Cost increase was due to additional project management costs, by both Federal and Local Sponsor.

Surveys identified a pipeline in the crevasse area which would be negatively impacted by the project. US Fish & Wildlife Service reviewed their permit for the pipeline and determined that Shell Pipeline was required to lower it at their own cost. USFWS requested a modification to the alignment on USFWS-owned lands.

Construction complete.

FUND STATUS:

The current project estimate is $884,270 , which includes $495,207 for construction first costs, and $389,063 and $0 for 20 years of monitoring and operations and maintenance, respectively.
