5. 8. CC Regular Session Meeting Date: 08/08/2023 Primary Strategic Plan Initiative: Address infrastructure needs. Information Title Adopt Resolution #23-177 Accepting Quotes and Awarding Contract for Street Maintenance Project #23-23, 2023 Spray Patching Contracted Services. Purpose/Background: Purpose: The purpose of this case is to adopt Resolution #23-177 accepting quotes and awarding a construction contract for Street Maintenance Project #23-23, 2023 Spray Patching Contracted Services. Background: Many miles of City streets have significant numbers of potholes deeper than 2-inches and/or numerous areas where the upper 2-inches or less of pavement are missing, generally termed surface stripping, resulting in poor and unsafe conditions for drivers and pedestrians. The number of streets with deep and shallow (surface stripping) potholes have grown significantly in recent years, resulting in Public Works staff spending more and more time patching potholes and less time completing other core duties. In 2023, the number of streets with significant numbers of deep potholes and surface stripping have increased to the point that Public Works staff are able to maintain only a small portion of them. This is due in part to last winter's severe weather conditions, but also due to the age and composition of the pavement sections, as well as not receiving regular proactive maintenance treatments over the life of the pavement sections. In April, Staff finalized the attached overall pavement repair plan showing all streets proposed to receive temporary 2-inch mill and overlays, temporary deep pothole patching, and temporary spray patching to most cost-effectively maintain pavement sections on the worst streets until they can be reconstructed. Deep pothole patching involves removing all debris and water from potholes deeper than 2-inches using compressed air, applying bituminous tack coat on existing bituminous pavement surfaces within the potholes, placing hot asphalt mix in the potholes, then compacting the hot mix. Spray patching involves using a spray patching truck to clean debris and water out of potholes 2-inches deep or shallower using compressed air, then applying a bituminous spray patch mix within the shallow potholes. On April 25, 2023, the City Council adopted Resolution #23-089 approving plans and specifications and authorizing advertisements for bids for Improvement Project #23-14, 2023 Critical Mill and Overlay Improvements. The intent of this project, which is complete, was to temporarily repair distressed pavement sections in 21 of the most critical areas by completing 2-inch mill and overlay improvements. That same evening, the City Council directed the City Engineer to solicit quotes for contracted pavement patching services to immediately patch as many of the highest priority potholes as practical. This project, which was designated project #23-15, Priority Pothole Patching, was completed in early June. On April 25, 2023, the City Council also directed the City Engineer to prepare plans for enlisting contracted services to patch all remaining streets shown on the overall pavement repair plan and to present said plans to the City Council on May 9, 2023, to authorize bids. Attached are two figures showing the remaining streets that Staff identified as requiring temporary pavement repairs in the form of deep pothole patching (Figure 1) and spray
