MI-1 4th Avenue Project Ready for Flood Protection
-- UPDATE --
December 30, 2021
2021 was a busy construction season for crews working on Phase MI-1 4th Avenue bringing nearly all of this phase of the flood protection project to substantial completion. Phase MI-1 of the Mouse River Enhanced Flood Protection Plan (MREFPP) is ready for the 2022 flood fight if needed. The project is scheduled for completion in 2022 and a ribbon cutting to mark this milestone is on the horizon.
A portion of the Mouse River Enhanced Flood Protection Plan, Phase MI-1 4th Avenue, includes over 2,250 feet of floodwalls located between just west of Broadway and just west of Third Street NE. The project also includes earthen levees on both sides of where the Broadway Bridge connects on the north side of the river and two removable closure structures in the flood wall.
Highlights from this construction season include:
Successful testing of the Broadway Pump Station, a stormwater pump station at Broadway and Fourth Avenue NW. In June, successful tests of all seven pumps (4-40,000+ gpm and 3-7,000 gpm) were completed, with crews monitoring all operations of the equipment and the station.
New sidewalks and curbs on the east side of Broadway allow for safer access to pedestrians and easier maintenance of sidewalks for businesses along 4th Avenue.
Landscaping completed on the north side of the floodwall which brings in the finishing touch to highlight the flood wall and main intersection of Broadway and 4th Avenue NW.
Privacy fences were installed for homeowners along 4th Avenue NW.
