The U.S. Army Corps of Engineers, St. Paul District, in cooperation with the Flood Diversion Board of Authority, announced on Thursday the final diversion channel alignment for the proposed Fargo-Moorhead (FM) Area Diversion Project.

The Corps of Engineers revised the diversion channel alignment and associated features since publishing its Final Feasibility Study and Environmental Impact Statement, or EIS. The changes result in significant cost savings, reduce the number of impacted residential structures, reduce impacts to Richland and Wilkin counties, and increase efficiency and operation of the diversion channel.

Changes were made to the western alignment, south of the Maple River to the Sheyenne River, and the southern alignment. The western alignment change resulted in moving the diversion channel west of the Highway 94/Raymond interchange and the existing Sheyenne Diversion Project, leaving the Horace to West Fargo diversion channel separate from the proposed diversion channel.

Changes to the southern portion of the project included adding gates on the inlet structure, moving the diversion approximately one mile north, adding levees through town and eliminating Storage Area 1.

Update: four alignment maps show the overall alignment, the Maple River to the Diversion Outlet, the Sheyenne River to the Maple River, and the Inlet to the Sheyenne River.

It is important to note that these changes are not considered final until the supplemental Environmental Assessment is complete, which is scheduled for August 2013.

The Corps and Diversion Authority will continue to work together to improve the project and inform the public of all decisions.

Pdf copies of PowerPoint presentations made to the Diversion Authority on November 8 are available in the Technical Documents section.
