Item C: General Obligation Bonds for Street Maintenance

pedestrian paths. In all cases, bond funds would be used only to preserve existing elements, not to expand the capacity of the system, for instance, by installing new traffic lights or bike lanes. An initial list of street preservation projects to be funded from the bond proceeds has been developed based on data from the pavement management system. The pavement management system incorporates street data including surface descriptions and associated mileage, pavement condition and current treatment programs and costs. The system then uses that data to project future treatment needs. The 2008 Pavement Management Report generated from this system is included as Attachment B. Attachment C sets out the initial list of projects generated by the pavement management system. This list allocates all of the bond proceeds, except for the portion that would be used for the annual $350,000 allocation for preserving off-street bike and pedestrian paths. The next step in developing this list into a set of projects for the bond measure is to consolidate some of the street segments identified as needing overlay or reconstruction during the next 10 years into logical street preservation projects that would be done concurrently. For instance, the list contains several segments of a street, such as Willamette, with some gaps in-between. The actual project undertaken might include a contiguous length of Willamette, including those short portions not originally identified by the pavement management system, depending on the condition rating of those other portions. In that way, staff would ensure that a single street is not under construction each year to repair different small segments, but the street is repaired in a more comprehensive way. When staff brings back the bond resolution for council consideration in July, the project list will be refined to take this consolidation of street preservation projects into account. The council also expressed interest in ensuring that any list of street preservation projects to be associated with the bond measure be geographically distributed throughout the community to make certain that all areas of the City receive a benefit from the bond proceeds. In order to allow council and the public to more easily see the geographic distribution of streets on the project list, a map of the initial list of street preservation projects is included in Attachment D. Note that the map does not include the off-street bike and pedestrian paths that will be overlaid or reconstructed with the $350,000 annual allocation. Project Implementation Over the life of the bond measure, pavement conditions or circumstances could change, making it more fiscally prudent or a higher community priority to spend funds on street preservation projects which were not anticipated in 2008. For example, current street condition ratings, as determined by the City’s pavement management system and additional testing, may change due to unanticipated severe weather which might warrant priority overlays on streets not previously identified as “at risk” or not otherwise due for an overlay for several years. In addition, future street repair costs cannot be predicted with absolute accuracy, and adjustments to the project list might be needed to match the list of projects to the amount of available bond proceeds. To address the flexibility needed to conform the GO Bond project list to the amount of bond proceeds available over the 10-year period, the resolution would include a provision for a Department Advisory Committee named the Street Preservation Advisory Committee (Committee). The Committee would advise the Public Works Department about the street preservation projects to be funded by each year’s capital budget. It would be comprised of a variety of stakeholders from various geographic areas of the City and would include members with expertise in street preservation activities. The Public Works Department would take the recommendation of the Committee into account when compiling the annual Z:\CMO\2008 Council Agendas\M080609\S080609C.doc
