The following graph identifies the trigger points (PCI) for each treatment based on Functional Class. Project Prioritization Selecting streets or street segments for treatment is done through a process involving analysis, testing, and staff experience. Using the data produced by MicroPaver, and combining this information with estimated revenues allows staff to approximate backlogs and group potential street segments for consideration for treatment under the Pavement Preservation Program. Streets are not prioritized on a "worst first" basis. Public Works' main objective is to keep street segments from slipping into the reconstruction category, which typically costs four to five times more per lane mile than rehabilitation. By rehabilitating (overlaying) a street before it significantly deteriorates, 15 to 20 years of useful life can be added to a street at a substantial cost savings over reconstruction. Once a street has deteriorated to the point that it must be reconstructed, the opportunity for preventive street maintenance (overlay) is lost. For these reasons, streets that are categorized as overlay projects receive the highest priority for corrective treatment. If at some point in the future there are additional funds available, or if the majority of overlay projects have been addressed, reconstruction projects will be scheduled. A prioritized list of 32 street repair projects to be funded by a local bond measure was approved by Eugene voters in 2008. The list, approved by City Council, was developed by staff based on citizen input, information about needed street rehabilitation and reconstruction from the pavement management system, and equitable geographic distribution of projects throughout the 14 PCI Treatment Range by Functional Cllass NMI 2,122,111"M ANN Ammr16cis�c1 .......................... ............................ .... ................. 0 10 20 30 4110 50 60 70 80 90 100 Project Prioritization Selecting streets or street segments for treatment is done through a process involving analysis, testing, and staff experience.
