Phase WC-1B Tierrecita Vallejo Currently In Construction

August 1, 2022
PHASE WC-1B CONSTRUCTION UPDATE
Phase WC-1 of the Mouse River Enhance Flood Protection Project has been underway in the Tierrecita Vallejo neighborhood since Wagner Construction began in August of 2021. This phase was divided into two construction contracts which allowed for an extension on negotiations of property acquisitions. The second contract for this phase was also secured by Wagner Construction and began in the spring of 2022.
The second phase, WC-1B, began in the spring of 2022 with clearing and grubbing of trees and foliage. This section features a seepage cutoff like those installed in the Burlington Phases using the one pass trenching method. The seepage cutoff wall extends to a depth of 35’ and was installed in early July. Levee fill is on-going and will continue through late summer. Levee fills, upwards of 30 feet, are required through this low-lying area to meet design specifications for proper flood protection. The existing water control structure in the Mouse River will also be replaced as part of this phase. A rock riffle will be constructed utilizing a series of cascading steps created with boulders which provides a similar gradient control for the river in a more natural and environmentally friendly fashion. Construction of both contracts for Phase WC-1 are scheduled to be completed by the end of the 2022 construction season.
Phase WC-1 Tierrecita Vallejo
urban flood control
Tierrecita Vallejo is a rural residential subdivision located near the northwest corner of the US 83 bypass and Highway 2 intersection, directly west of Jack Hoeven Park. Shortly after the flood of 1907, the USACE constructed a flood control project for the subdivision consisting of a levee, gate wells, and a portable pump. Following the 2011 flood, the Tierrecita Vallejo neighborhood was included in the scope of the Preliminary Engineering Report (PER) with the recommendation for the reconstruction of the levees, a railroad crossing structure, and storm water lift station. Ultimately, the proposed levee system will serve as the west tieback for the MREFPP Phase MI-2 project and provide an increased level of protection for the City of Minot.
Since the PER was developed, other projects are either under construction or have been constructed that will allow for modifications to the proposed PER recommendations that will both save construction time and cost. The proposed levee will extend west from the new US 83 bridge and follow the north bank of the Mouse River, cross the Canadian Pacific Railroad and head north. The levee will feature a closure structure across the railroad allowing Canadian Pacific Railroad continued operation while still protecting the Tierrecita Vallejo residents. Work completed as a part of the Phase MI-2 project will allow the design team to modify the preliminary design by removing the ponding area, eliminating the proposed storm water lift station, and modifying the existing gate wells to maintain water
