MI-4 Maple Diversion South Utility Relocation Project Reaches Substantial Completion

-- UPDATE --

December 30, 2021

Phase MI-4A utility relocation in front of the larger MI-4 Maple Diversion project is substantially complete. 2021 marked year two of construction on this phase where all utilities have been installed and the sanitary pump station is now operational.

Phase MI-4A of the Mouse River Enhanced Flood Protection Project (MREFPP) started construction at the end of August 2020. The purpose of MI-4A (Maple Diversion South Utility Relocations) is to relocate municipal utilities in advance of the flood protection features proposed as part of the Phase MI-4A Maple Diversion Project. Construction on this phase is scheduled to be fully completed in 2022.

Highlights from this construction season include:

  • Installation of new underground watermain pipe.

  • Installation of a new sanitary sewer lift station and associated underground piping.

  • New permanent barriers completed at the railway crossing connecting Burdick Expressway to 4th Avenue SW which comply with quiet zone requirements.

  • New asphalt pavement and curb and gutters along Western Avenue SW and 2nd Avenue SW.

Phases MI-4/MI-4A Maple Diversion

urban flood control

After a three-year USACE Feasibility Study, it has been 

determined that there is a federal interest in this phase of the

project. The Souris River Joint Board is waiting to learn if there will

be funding appropriated.

 

The design of Phase MI-4 Maple Diversion has continued and is

nearly complete. Phase MI-4 continues where Phase MI-3 left off

and runs northeasterly to tie into the west end of Phase MI-1. Phase MI-4 includes an excavated high flow diversion channel, upstream and downstream river closure structures, an upstream weir structure, earthen levee segments, and closure structures across the Canadian Pacific Railroad and 6th Street.

 

Both 6th Street and Canadian Pacific Railroad would be realigned as a part of the project and a railroad bridge would be constructed of the diversion channel. Additional features include a shared use path and aquatic recreation opportunities.

 

In order to be in a position to begin construction should funding be appropriated, the project has been broken into several phases including MI-4A which includes the relocation of existing municipal utilities in order to clear the path for the project. This phase began construction in August 2020 and is scheduled to be fully completed in 2022.

The total project cost is estimated at $85 million. If the project is federally authorized and appropriated, the federal share of the cost would be 65% and the state and local share would each be 17.5%.

 

The Feasibly Study only includes the north side levees of the Maple Diversion. In the future, if the project sponsor wishes to add protection on the south side, it would not be a part of the potential federal project.
