CC Regular Session 7, 5, Meeting Date: 08/08/2022 By: Bruce Westby, Engineering/Public Works Information Title: Adopt Resolution #22-176 Accepting Bids and Awarding Contract for Improvement Project #20-05, Riverdale Drive Extension, Llama Street to Bowers Drive Purpose/Background: Purpose: The purpose of this case is to adopt Resolution #22-176 accepting bids and awarding a construction construct for Improvement Project #20-05, Riverdale Drive Extension, Llama Street to Bowers Drive. Background: The extension of Riverdale Drive between Llama Street and Bowers Drive is needed to support future development in the area. Capstone Homes is currently constructing the first phase of the Riverstone South residential development, which upon completion will include 244 single-family units northeast of Bowers Drive and south of U.S. Highway 10/169. Commercial development is also proposed between U.S. Highway 10/169 and the proposed extension of Riverdale Drive. Also, approximately 100 acres of undeveloped property exists immediately east of the Riverstone South development. Improvement Project #22-05 is currently under construction to extend trunk municipal utilities (sanitary sewer and watermain) along the proposed extension of Riverdale Drive between Llama Street and Bowers Drive, a sanitary sewer list station, and required storm sewer improvements for Riverdale Drive. These utility improvements are being constructed ahead of Improvement Project #20-05 to facilitate the construction schedule of Riverstone South. Improvement Project #20-05 proposes to reconstruct the segment of Riverdale Drive east of Llama Street that was not reconstructed with the Armstrong Boulevard and Highway 10 interchange improvements, which measures approximately 1,280 linear feet (0.24 miles). This project also proposes to extend Riverdale Drive and a regional trail from Llama Street to Bowers Drive, which measures approximately 4,250 linear feet (0.8 miles). Both street segments will be constructed with bituminous pavement meeting a 10-ton design strength measuring 40-feet wide between the concrete curb and gutter faces. The bituminous trail will be 10-feet wide. This extension of Riverdale Drive will become part of the City's Municipal State Aid (MSA) street system, meaning it will generate MSA funds moving forward and must therefore be constructed to MnDOT design standards. Additionally, this project proposes to construct a trunk watermain line to connect the trunk watermain lines under Riverdale Drive and Bunker Lake Boulevard. This watermain will be installed in a sleeve under Highway 10 and the BNSF railway, and will provide a looped watermain system. Notification: Advertisements for bids were published in the Anoka Union Herald and in Finance & Commerce as required by State Statute. The project was also advertised and bid electronically through QuestCDN. Engineering Staff maintains a project webpage, which will be updated with new information throughout construction.
