Public Works Committee 5. 5. Meeting Date: 01/19/2021 By: Bruce Westby, Engineering/Public Works Title: Consider Recommending City Council Approval of Plans and Specifications and Authorization to Advertise for Bids for 2021 Crack Seal Improvements, Improvement Project #21-06 Purpose/Background: Purpose: The purpose of this case is to consider recommending City Council approval of plans and specifications and authorization to advertise for bids for 2021 Crack Seal Improvements, Improvement Project #20-06. Background: Crack seal improvements are completed on numerous public street segments annually to cost-effectively maximize the life of the bituminous pavement. Crack sealing protects pavement by preventing stormwater runoff from seeping through cracks in the pavement and joints between the pavement and concrete curb and gutter and utility castings, reducing future pavement damage due to wet subgrade soils, especially during freeze -thaw cycles. The City's typical maintenance schedule calls for public streets to be crack sealed 3 years after construction, reconstruction, or overlay improvements. While this is the typical maintenance schedule, it is important to note that Staff reviews the condition of all streets annually and adjusts the schedule of maintenance operations based on actual pavement conditions. Although the City has indefinitely suspended sealcoat projects, Staff is evaluating the potential for completing a new pavement rejuvenation project in 2021, similar but in larger scale than the project completed in 2020. Staff proposes to discuss this in more detail with the Committee at their February meeting. Plans and specifications for the 2021 Crack Seal Improvements were prepared in-house as part of Staff's normal duties. A copy of the plans are attached to this case. A total of 21.05 miles of public street segments are proposed to receive crack seal improvements in 2021. These street segments were selected based on their maintenance history, age, and Pavement and Surface Evaluation Rating (PASER). Timeframe: Staff estimates 10 minutes will be required to present this case and respond to questions. Observations/Alternatives: Alternative #1 — Motion recommending City Council approval of plans and specifications and authorization to advertise for bids for 2021 Crack Seal Improvements, Improvement Project #20-06. Alternative #2 — Motion of other. Funding Source:
