• Receive mill and overlay when deemed preventative maintenance will not benefit pavement life Poor condition • Minimize maintenance dollars • Reconstruction Mr. Schwartz noted that priorities are based on condition, as well as proximity to other construction projects; provided examples of various street conditions; and addressed installation of curb and gutter as part of projects, with the only street without City jurisdiction at this time not having curb and gutter was Victoria Street south of County Road B. Mr. Schwartz also provided a number of twenty (20)-year graphs, as a bench handout, regarding current funding levels and budgets versus a backlog for capital improvements, as used by staff in budget modeling for current spending and current street conditions for recommendation to the City Manager and City Council for future funding needs in the PMP. Mr. Schwartz noted the current 80% overall condition network versus how it diminished at the end of twenty (20) years for the overall PCI. Mr. Schwartz noted that a significant part of this diminished fund availability was due to reduced interest rates and return on investment for the PMP at approximately a 3% return versus previous returns of between 5-7%. Mr. Schwartz noted that other impacts were inflation related, as well as increased cost of materials while interest rates continued to decline. Mr. Schwartz noted the dramatic difference shown by the graphs in maintaining street conditions in "perfect" condition; assumptions of the program for bringing segments up to 100% compared to the City's standard practice to achieve an overall condition at 75-80%; and whether the City needed to reconsider desired standards for future maintenance and construction. Mr. Schwartz noted that pavements as now constructed throughout the City lasted about thirty (30) years versus projected twenty (20) years, particularly lesser traffic volume streets. Discussion included projected traffic patterns in the future (e.g. fewer and lighter cars, more bicycles, economics, and trends of multi-modal options) dependent on which part of the metro area was addressed (e.g. inner-ring suburbs versus those further out). Mr. Schwartz noted that there were a number of variables affecting road conditions, including the type of traffic, and impacts of freeze/thaw cycles. Further discussion included private streets inadvertently included on the condition map; current projections by staff to the City Manager and City Council over the next 3-7 years to add an additional $1 million funding to the PMP to maintain current PCI, and allowing time to make adjustments during that period based on how the fund perform; with the CIP Task Force addressing that with their Page 8 of 11
