Public Works Committee Meeting Date: 04/18/2023 By: Bruce Westby, Engineering/Public Works Title: Consider Recommending City Council Approval of 2023 Temporary Pavement Repairs Plan 5.2. Purpose/Background: During the 2023 budget process, $750,000 was budgeted to the streets maintenance fund for temporary spray patching improvements on an estimated 19 miles of City streets to help hold pavement together on streets experiencing significant surface stripping but that are not identified for overlay or reconstruction improvements in the 2022 - 2031 Capital Improvement Program (CIP). Pavement on these streets will be prone to accelerated deterioration due to water pooling in the surface depressions, which is then forced between the pavement base and the wear courses as vehicle tires drop into the depressions and push the water into pavement voids. The rideability on these streets will also continue to decline while other streets are receiving overlay and reconstruction improvements. Staff therefore recommended spray patching these streets while PMP projects in the 2022 - 2031 CIP are being completed, and as streets constructed between 1975 and 1985 having PASER ratings of 4 or less that are not included in the 2022-2031 CIP can be reconstructed. See attached Public Works Committee case #13431 from July 2022. Staff has since been developing a plan to contract such temporary pavement repair work in 2023, but in the course of developing this plan it was observed that several different types of pavement repairs would be needed to most cost-effectively maintain pavement on streets awaiting overlay and reconstruction improvements. The different types of pavement repairs recommended by Staff for 2023 include spray patching, pothole patching, and spot mill and overlay improvements, along with striping after this contracted work is complete, when needed. Timeframe: Staff estimates 30 minutes will be needed to present this case and respond to questions. Observations/Alternatives: Staff was in the process of finalizing maps and quantities at the time this case was prepared but in the interest of time and the City's immediate pavement repair needs, Staff wanted to bring this case to the Public Works Committee as soon as possible. Staff will present maps and supporting data during the meeting. Funding Source: 2023 budgeted street maintenance funds. Recommendation: Staff will provide their recommendations during the meeting. Action: Based on meeting discussions. AgendaQuick case #13431 Attachments Form Review
