Phase MI-2C, also referred to as the West Peterson Coulee Outlet, is a storm sewer project located near the West Hills Acres and West Ridge Estates subdivisions, along Ward County Road 15 immediately west of Minot. Wagner Construction completed the installation of the 48-inch, 60-inch, and 66-inch RCP storm sewer pipe in fall of 2022 despite delays in material procurement as a result of limited precast pipe suppliers in the region. The 9’ x 6’ precast box culvert beneath 41st Street NW and dual 60-inch RCP culverts installed beneath Harmony Street were also installed last fall. Final restoration, seeding, and erosion control measures were completed in spring of 2023.

The newly installed storm sewer serves as a bypass, redirecting storm water runoff that would typically follow the ditch along the US Hwy 83 bypass around the Tierrecita Vallejo and Napa Valley levee system. The bypass allows for runoff to be directed around the City’s levee system, minimizing the infrastructure required to provide interior drainage along the dry side of the levee.
