5.02: Consider Recommendation to City Council to Temporarily Increase Funding for Pavement Management Program and Street Maintenance Budget City Engineer Westby reviewed the staff report and recommendation of staff to temporarily increase annual PMP funding to mitigate unmet street reconstruction bubble needs, to minimize annual maintenance costs, and to minimize the term of the increased funding as much as practical to reduce impacts to the street maintenance budget including equipment and material costs, professional services, and staffing. However, as annual PMP funding amounts increase, so will impacts to engineering costs including engineering staff and professional services. Staff recommends increasing the street maintenance budget by $750,000 to allow an estimated 19 miles of streets to be spray patched while PMP projects in the 2022-2031 CIP are completed, and as streets constructed between 1975 and 1985 having PASER ratings of 4 or less that are not included in the 2022-2031 CIP can be reconstructed. Chairperson Riley commented that the roads are in the worst shape they have been and in discussions with staff it seems that spray patching helps to delay the deterioration of the roads. He stated that all this work needs to be done as soon as possible and acknowledged that the budget is one issue as is staffing and equipment. He asked if there were a budget for it, could the spray patching be done in two years through contracted services. He also asked if it would be more economical to purchase the equipment necessary to do spray patching. Public Works Streets Supervisor Turner replied that he could reach out to the contractor to determine if that would be feasible. Councilmember Woestehoff asked the realistic extension of life that spray patching provides. Public Works Streets Supervisor Turner replied that realistically the spray patching provides another five years, which is a band -aid to help the City through this bubble it is in. Councilmember Woestehoff noted the mention of completing this in two years but stated that perhaps it is done over five years and then perhaps that helps to stagger the needed overlay improvements. City Engineer Westby stated even if a street is spray patched, areas of the street that were not patched will continue to decay and require patching over time. Councilmember Woestehoff asked the right amount of spray patching per year and whether a set amount should be budgeted each year for spray patching until it is no longer needed. City Engineer Westby stated that staff could reach out to contractors to develop some options and recommendations that could come back next month. He noted that those discussions could also occur during the budget work sessions. Chairperson Riley asked the type of work being done on Xkimo near Alpine.
