PAVEMENT PRESERVATION PROGRAM <br />Street preservation and rehabilitation, capital improvements, off-street shared-use path projects, <br />and maintenance efforts make up PPP. Additionally, the City has budgeted funding for <br />Maintenance Operations to repair portions of the unimproved street system through the <br />Enhanced Street Repair Program. Both PW Maintenance and PW Engineering divisions have <br />important roles within the PPP. <br />PWMaintenance Roles <br />Maintenance Division Surface Technical team completes the pavement rating, budget and street <br />life analysis, resulting in a proposed list of projects which is forwarded to Engineering for field <br />testing and final grouping. Surface Technical staff is responsible for producing this report. <br />Operations staff is responsible for the preventative maintenance of all City streets (including <br />concrete streets) and off-street shared-use paths. Preventative maintenance designed to extend <br />the life of the transportation asset is of highest priority. Fully improved asphalt streets receive the <br />highest level of maintenance.Maintenance activities are performed to mitigate hazardous <br />conditions and to extend the useful life of the street. The goal of preventative maintenance is to <br />PCI from slipping from preventative maintenance or minor rehabilitation into a <br />reconstruction category. <br />PW Engineering Roles <br />The Engineering Division typically receives projects proposed for preservation from the <br />Maintenance Division three years in advance of the planned construction. Engineering then <br />performs field investigations to confirm the need for treatment, and reviews historic data on <br />construction and maintenance of the streets. Streets are then prioritized for detailed pavement <br />testing and design recommendations based on the available funding and the assessed condition of <br />the streets. The pavement testing and design reports identify whether a street needs to be <br />reconstructed or rehabilitated (overlaid) and the range of treatment options available. If a street is <br />determined to be a full reconstruct,it is typically deferred until funding is identified and <br />available, such as street repair bond measures. <br />The Engineering Division is responsible for capital project management including design, <br />stakeholder coordination and communication, contract administration, and construction <br />management. For analysis and reporting of projected backlogs, the Engineering Division has <br />provided construction costs based on historic and current road projects. <br />10 <br /> <br />
