City of Arden Hills Budget Analysis Report May 04, 2006 Page 2 system ranging from 100 for a newly surfaced pavement to 0 for a failed pavement. Based on the latest available survey data collected for each section, the average PCI of the Arden Hills pavement network using the PCI resulting from the survey is 67.9. The average PCI can also be calculated by projecting the surveyed condition to today's estimated PCI using the decay curves in ICON. Using these curves, the "current average projected" PCI for the network is a 64. The results of Scenario 1 indicate that the current level of funding and funding allocation will result in a higher average PCI each year and will decrease the backlog. Over the twenty-year analysis period, the average PCI increases significantly, from 64 to 77. The results of Scenario 2 indicate that a total of approximately $14.5 million will be required over the next twenty years to maintain the City's current average PCI of 64. Due to a significant amount of budget allocated in the first five years, the pavement can be maintained at a lower budget. The results of Scenario 3 indicate that a total of approximately $16 million will be required over the next twenty years to gradually increase the City's average PCI from a 64 to a 75. In comparison to Scenario 2, more budgets are spent in the first 10 years to increase the PCI to a 75. Then the pavement can be maintained at a 75 at a lower budget. The results of Scenario 4 indicate that the current elP list will maintain an average condition of 65 over the next five years. It is important to note that these scenarios were generated at the network level and were based on pavement repair and rehabilitation costs that may require additional project-level costs such as curb and gutter replacement, water main replacement, and/or right-of-way restoration. Also included in the cost is a 20% increase for engineering fees.
