CC Regular Session 7.2. Meeting Date: 01/26/2021 By: Bruce Westby, Engineering/Public Works Information Title: Adopt Resolution #21-022 Approving Plans and Specifications and Authorizing Advertisements for Bids for Riverdale Drive Reconstruction, Improvement Project #21-00 Purpose/Background: Purpose: The purpose of this case is to consider adopting Resolution #21-022 approving plans and specifications and authorizing advertisements for bids for the reconstruction of Riverdale Drive NW between Feldspar Street NW and Sunfish Lake Boulevard, Improvement Project #21-00. Background: City Improvement Project #21-00 proposes to reconstruct Riverdale Drive NW between Feldspar Street NW and Sunfish Lake Boulevard in 2021 per the 2021 - 2030 Capital Improvement Plan (CIP). The segment of Riverdale Drive that is proposed to be reconstructed totals approximately 2,925 lineal feet (0.55 miles). A figure showing the location and scope of the proposed improvements is included on the attached cover sheet of the plans. The pavement on this segment of Riverdale Drive is in very poor condition and Public Works Staff spend an excessive amount of time each year patching the pavement. In addition, Staff has received numerous complaints from the public in recent years regarding the poor condition of this pavement. On November 24, 20201 City Council accepted a proposal from Bolton & Menk, Inc. to provide design services for this project including collecting topographic survey data, completing geotechnical evaluations, preparing plans and specifications complying with Minnesota Department of Transportation (MnDOT) State Aid standards, providing required submittals to State Aid, and bidding services. Riverdale Drive is part of the City's Municipal State Aid (MSA) system and is therefore required to meet 10-ton pavement design strength standards, as well as other applicable MnDOT State Aid standards. Municipal utilities (water supply and sanitary sewer) exist in the project area. Sanitary sewer improvements are not proposed with this project as the sanitary sewer lines were cleaned and televised and the results verified that repairs are not immediately needed or anticipated to be needed during the 60-year design life of the improvements. Water supply improvements are also not proposed. However, water service lines extending from the trunk line to individual properties are proposed to be inspected at the right of way to confirm that each service line is properly tied back to the trunk line. This work will help ensure that service line repairs will not be needed during the design life of the proposed improvements, and is being proposed as repairs to several water service lines were made recently along this segment of Riverdale Drive. The water supply system was recently tested for leaks and the results indicate that repairs are not immediately needed or anticipated to be needed during the design life of the improvements. Storm sewer improvements are proposed with this project. This includes adding trunk storm sewer under Riverdale Drive to better convey stormwater runoff from the Dolomite Street intersection area to the Mississippi River, as well as adding a pollution control structure to remove pollutants from stormwater runoff before it is discharged to the river. Riverdale Drive is currently 44-feet wide from face -of -curb to face -of -curb, but is proposed to be reduced by
