the initial review of the geotechnical report, sub -soil conditions appear to be favorable and the assumed pavement <br />section of 4-inches new bituminous over 5-inches recycled aggregate base is anticipated to meet the required <br />10-ton MSA pavement strength design requirements. Due to construction, traffic counts of this section of Alpine <br />Drive are not current. Staff will perform traffic counts this fall after new traffic patterns from the Armstrong <br />Boulevard roundabout have been established. Traffic levels significant enough to impact the pavement design are <br />not anticipated, but it will be reviewed as part of final design. <br />PASER values have not been collected on this segment of Alpine Drive since 2021. At that time the PASER <br />value was 8, which was potentially high due to the seal coat covering much of the block cracking. Since 2021, <br />City Staff has seen a noticeable deterioration of the pavement, and would no longer recommend an overlay as an <br />appropriate treatment for the pavement. <br />Additional Permitting <br />Alpine Drive is an MSA street, which requires review and approval by the MnDOT MSA department prior to <br />bidding the project. Additionally, a Minnesota Department of Health Water Extension Permit will be required <br />before completing the trunk watermain extension. <br />Project Timelines <br />Staff is proposing to prepare plans and specifications for this project in-house, as part of their normal duties. The <br />following are the proposed general project timelines: <br />August 22, 2023 <br />Sep — Dec 2023 <br />Jan — Feb 2024 <br />Feb — Mar 2024 <br />May — June 2024 <br />Summer 2024 <br />City Council authorization to prepare plans and specifications <br />Staff prepares plans and specifications <br />City Council approves plans, authorizes bidding <br />Bid opening, City Council awards contracts <br />Begin Construction <br />Finish Construction <br />The street and watermain improvements proposed with this project are identified in the City's current 10-year CIP <br />for construction in 2024. They can be funded using a combination of Municipal State Aid Funds, Storm Water <br />Utility Funds, and Water Utility Funds. Staff proposes to construct these improvements as a stand-alone project. <br />Staff proposes to bid and award 2024 projects as close together as practical, which generally allows for a better <br />bidding environment for the City. This project is necessary, feasible, and cost-effective from an engineering <br />standpoint, and can be constructed as proposed herein. <br />Notification: <br />If City Council orders plans and specifications for this improvement project, Staff will send notification letters to <br />residents impacted by these improvements. <br />Observations/Alternatives: <br />Observations: <br />Estimates are CIP level and will be updated during the design process. <br />Alternatives: <br />Motion to adopt Resolution #23-201 ordering plans and specifications for MSA Alpine Drive Reconstruction, <br />Improvement Project #24-11. <br />Funding Source: <br />Funding for this improvement is proposed to come from Municipal State Aid Funds, Storm Water Utility Funds <br />and Water Utility Funds. <br />Municipal State Aid Storm Water Utility <br />Funds (Funds <br />rWater Utility Funds Total Project Funds <br />
