Consider recommending City Council authorization to prepare plans and specifications for 2024 MSA Pavement Overlay Improvements, Improvement Project #24-06

Purpose:
The purpose of this case is to consider recommending City Council authorization to prepare plans and specifications for 2024 MSA Pavement Overlay Improvements, Improvement Project #24-06.
 
Background:
The proposed 2024 – 2033 Capital Improvement Program (CIP) identifies five (5) Municipal State Aid (MSA) street segments for pavement overlay improvements for 2024. Street segment summaries are attached to this case.
 
Project Scope
This project proposes to mill and overlay 5 street segments, generally spread across 3 areas across the City. The projects total approximately 1.44 miles in length, and all segments are anticipated to receive a 2-inch thick mill and overlay improvements. The project areas include:

• 142^nd Avenue & Armstrong Boulevard
  • Generally located south of Riverdale Drive
  • Construction between 1981 and 1986
    • 0.84 miles of 24’ wide rural section
  • Overlay improvement in 2006
  • Crack seal / seal coat improvement in 2011
• 160^th Lane & Jasper Street
  • Generally located west of Ramsey Boulevard
  • Construction in 1985
    • 0.47 miles of mix 24’ wide rural and urban section with bituminous curbing
  • Overlay improvement in 2000
  • Crack seal / seal coat in 2007 and 2018
• McKinley Street
  • Generally located west of Azurite Street
    • West end terminates at the property line for the Public Works Facility
  • Construction in 1997
    • 0.14 miles of 40’ wide urban section with concrete curb and gutter
  • Crack seal / seal coat in 2003 and 2012

 
Proposed Improvements
Review of ground penetrating radar (GPR) data indicates sufficient existing bituminous thickness to perform a 2-inch mill and bituminous overlay in all project areas, which is being proposed. Per typical overlay improvements, spot concrete curb and gutter repairs will be performed on damaged curb. Where feasible, the City has switched to a saw & seal method for curb cracks at a significant cost savings. This is performed on hairline cracks, without vertical displacement. For the areas of bituminous curbing, repairs are not anticipated.
 
Municipal sewer and water only exist under McKinley Street. Staff is not proposing any repairs to watermain or sanitary sewer with this project. Minor storm sewer structure repairs, typically re-grouting catch basins, is proposed.
 
The project areas do not have any pedestrian facilities, so no upgrades to pedestrian ramps will be required with these improvements.
 
Project Timelines
Staff is proposing to prepare plans and specifications for these improvements in-house, as part of their normal duties. The following are the proposed general project timelines:
 

• November 28, 2023    City Council authorization to prepare plans and specifications
• Jan. – Mar. 2024         Staff prepares plans and specifications
• Mar. – Apr. 2024        City Council approves plans, authorize bidding
• May – June 2024        Bid opening, City Council awards contracts
• Summer 2024              Construction

 
Staff proposes to bid 2024 projects separately, but to bid and award projects as close together as practical, which generally allows for a better bidding environment for the City.

Notification is not required for this case.

Timeframe:
Staff anticipates this case will take approximately 10 minutes to present and respond to questions.
 
Observations:
Estimates are CIP level and will be updated during the design process.
 
Alternatives:
Alternative #1: Motion to recommend City Council authorization to prepare plans and specifications for 2024 MSA Pavement Overlay Improvements, Improvement Project #24-06.
 
Alternative #2: Motion of other.

Funding for this improvement is proposed to come from Municipal State Aid Funds and Stormwater Utility Funds.
 

• Street project costs                  $366,900
• Stormwater project costs        $18,345
• Total project costs                   $385,245

Staff recommends alternative #1.
