Public Works Committee 5. 4. Meeting Date: 04/18/2017 By: Bruce Westby, Engineering/Public Works Title: Consider Recommending City Council Approval of Plans and Specifications for Improvement Project # 17-00, Sunwood Drive Reconstruction Purpose/Background: Purpose: The purpose of this case is to consider recommending City Council approval of plans and specifications for Improvement Project #17-00, Sunwood Drive Reconstruction. Background: Attached are current plans for Improvement Project #17-00, Sunwood Drive Reconstruction. These plans are being reviewed by MnDOT State Aid. Approval by State Aid must be received before the City can bid the project. Staff anticipates receiving State Aid approval prior to requesting City Council approval of plans and specifications and authorization to bid the project on May 9th. This schedule would allow construction to begin in late June and to be substantially complete by September 1st. The design represented in the attached plans is generally consistent with the design as discussed with the City Council and addressed within the Feasibility Report. The only significant difference is that instead of milling 3+ inches off the top of the existing pavement and hauling it off site, all of the existing bituminous pavement will be reclaimed and mixed with the existing aggregate base, then 4 inches of the reclaim material will be hauled off site to allow for 4 inches of new bituminous pavement to maintain existing elevations. The project also proposes to install 6 inches of stabilized reclamation material now instead of 5 inches as proposed in the Feasibility Report, thereby providing a stronger pavement section. The Feasibility Report identified estimated costs in the amount of $607,000. The current estimated project costs per the attached plans are $571,539.48. Special assessments are proposed to pay for 25% of the total project costs. Timeframe: Staff estimates 10 minutes will be required to present this case and respond to questions. Observations/Alternatives: Observations: Staff is working with property owners to ensure they are fully aware of the current plans and tentative schedule to reconstruct their driveway accesses. Alternatives: Alternative # 1 — Motion recommending City Council approval of plans and specifications for Improvement Project #17-00, Sunwood Drive Reconstruction. Alternative #2 — Motion of other. Funding Source: Staff proposes to fund the proposed improvements using a combination of special assessments, street reconstruction bond funds, and stormwater utility funds.
