The Napa Valley segment of the project begins at the west edge of Minot at the Highway 83 Bypass and ends at 16th Street SW across the Mouse River from the Minot Water Treatment Plant, on the north side of the Mouse River. The features through this segment of the project are predominantly earthen levees with an average height of approximately 14 feet. The existing levees through this stretch have an average height of approximately 7 feet. The Napa Valley segment includes a transportation closure structure at 16th Street SW which consists of a removable barrier floodwall which is put in place only during large flood events. The Napa Valley segment of the project includes a storm water pump station in the vicinity of 7th Ave and 20th Street SW, approximately 2 blocks south of Perkett Elementary School.

The Napa Valley levee impacts the Souris Valley and Wee Links Golf Courses. Impacts to these courses were mitigated by modifying the course layout and moving and reconstructing the features that are impacted. The Dakota Bark Park, located on the west end of the project, is impacted by the new levee. These impacts were mitigated to the park by re-configuring the existing fences and shelter in locations close to the existing park.

The access to Wee Links will changed with new access off of 16th Street in the vicinity of Forest Road. The new access and parking lot for Wee Links will also serve area fishermen. The fishing pier near the Minot Water Treatment Plant was relocated to the north side of the river, adjacent to the new Wee Links parking lot.

Construction began in 2018 and was completed in 2020.
