Review of Trash Collection Impacts Section 2 - 2 occurs after roadways drop to a PCI score of 60 or lower. Studies have shown that every dollar spent performing preventative maintenance on a roadway with a PCI of 70 or higher saves $4 in future costs — it would otherwise cost about $5 to rehabilitate the same roadway once rapid deterioration occurs' (as shown in Figure 1). Ensuring adequate funding for an effective pavement management system is, therefore, critical to achieving a cost effective pavement management system. Pavement Condition Index Figure 1 Good Roads Cost Less to Maintain Pavement Condition Index Goal 70+ st $5 5 years 10 years 15 years 20 years 25 years The goal of a pavement management program is to bring all roads up to a "good" to "excellent" condition where they can be maintained most cost effectively. The strategy often recommended is referred to as the "Best First Approach ", which concentrates spending initially on routine and preventative maintenance on those roads that are currently in "fair" to "good" condition. This extends the useful life of those roads, preventing rapid deterioration. Spending money on routine maintenance now prevents additional spending in the future on more expensive repairs. The City's goal is to maintain a PCI of greater than 70 which falls within the "Good" range. The City has been able to maintain its streets at or near this target which has allowed it to provide cost effective maintenance. The 2008 and 2009 approved budgets, however, do not provide sufficient funding to maintain streets at their current level. The 2008 budget is more than $1.0 million less than that required to maintain streets at their current level while the 2009 budget is more than $2.5 million less than required. If ' J.
