This amount reflects the original contract amount of $765,000, plus quantity changes totaling $7,779.61, or 1% more than the original contract amount.

BACKGROUND The Public Works Services Department (“PWSD”) is responsible for the maintenance and repair of approximately 147 miles of paved streets within the City. As part of the City’s Pavement Management Program, the conditions of all City streets were inspected and rated on a scale of 0-100, with scores below 40 generally being considered a street that has failed. Scores between 40 and 60 are poor/fair in nature. This rating is called the Pavement Condition Index (“PCI”) and is used to help determine which streets require asphalt pavement rehabilitation. According to the Citywide Pavement Management Program, the following street segments were included in this year’s project: Accept 2020-21 Pavement Rehabilitation Project March 15, 2022 Page 2 of 3 • Arbolada Drive from San Carlos Road to Rancho Road – PCI of 53 • Camino Real Avenue from Sixth Avenue to Eighth Avenue – PCI of 46 • Lemon Avenue from West City Limits to Baldwin Avenue – PCI of 48 • Lemon Avenue from Holly Avenue to El Monte Avenue – PCI of 55 • Wilson Avenue from Grand View Avenue to Virginia Drive – PCI of 43 It should be noted that PCIs alone do not determine which streets should be rehabilitated; for instance, the City also takes into consideration the streets that have high traffic volume. Furthermore, it is more cost efficient to repave streets prior to their PCIs lowering to very poor condition. Once a street falls into the lower scoring ranges, grind and overlay would not be sufficient, and a more extensive rehabilitation such as a full depth reconstruction would be needed. DISCUSSION On August 3, 2021, the City Council approved a contract with Onyx Paving Company, Inc. for the Fiscal Year 2020-21 Pavement Rehabilitation Project. The work performed included repairing localized potholes and failed pavement, grinding the edges of the pavement adjacent to the gutters to transition the new pavement to the existing gutter, replacing broken curb and gutter as necessary, and installing new ADA-compliant curb ramps at the intersections. The new pavement surface utilized recycled rubber in the pavement mix to help reduce future cracking and to add strength to the asphalt pavement. The rubber in the pavement mixture also reduces road noise. Following the repairs, the condition of all relevant street sections was raised to a PCI of 100. During construction Macadam base material was discovered on Arbolada Drive, Camino Real Avenue, and Wilson Avenue. Macadam material cannot be recycled at a normal site and had to be transported to a special dumpsite. Additional asphalt material was also needed due to the required removal. Furthermore, various PCC concrete quantities of items of work were deducted or added to the project based on actual requirements in the field. Below is a full list of change orders that show the deductions or additions to the Project. CCO Description Amount 1.
