Phase WC-1 Tierrecita Vallejo Currently Awaiting Construction
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 levels within the existing cutoff meander.
Design has been completed on this phase of the project. The initial field work consisting of soil borings, topographic survey, and wetland delineation have been completed. Preconsolidation piles have been set. The project is expected start construction in 2020.
