Adopt Resolution #21-305 Ordering Plans and Specifications for Improvement Project #22-05, Riverdale Drive Trunk Utility Improvements, Llama Street to Bowers Drive

Purpose:
The purpose of this case is to adopt Resolution #21-305 ordering Plans and Specifications for Improvement Project #22-05, Riverdale Drive Trunk Utility Improvements, Llama Street to Bowers Drive.
 
Background:
The case is need to prevent the long plan review schedule required for Improvement Project #20-05, Riverdale Drive Extension, Llama Street to Bowers Drive, as outlined in the previous case, from unnecessarily delaying construction of the proposed Riverstone South residential development.
 
Since LPP funds are being utilized as source of funding for Improvement Project #20-05, MnDOT requires a significantly more complex plan review process that will extend the anticipated plan approval schedule for that project to the summer of 2022, meaning construction of those improvements may not occur until late summer or fall of 2022.
 
To better facilitate the proposed construction schedule for Riverstone South, the trunk utilities work (Improvement Project #22-05) is being pulled out of Improvement Project #20-05, which will prevent the trunk utility plans from needing to run through the same MnDOT LPP plan review process, thereby allowing this work to be bid this winter and constructed next spring/early summer.
 
This work is expected to take up to 8 weeks to construct, including the lift station within the Riverstone South plat.  Staff will work to properly coordinate this trunk utility work with the developers private utilities work.  
 

Notifications are not required for this case. 
 

Observations:
The extension of Riverdale Drive between Llama Street and Bowers Drive is needed to support future development in this area. Capstone Homes currently proposes to begin construction in 2022 on the first phase of Riverstone South, a 244-unit residential development east of Bowers Drive and south of U.S. Highway 10/169.
 
Commercial development is also proposed in the area between U.S. Highway 10/169 and the proposed extension of Riverdale Drive. These developers will pay into the trunk utility fund at the time they develop, helping to replenish the enterprise funds.
