SIGNIFICANT SYNOPSIS EXCERPTS

Scenario 1: City’s Existing Funding ($3.45 million/10 Years) Based on the City’s existing funding level of $345,000 per year for the next 10 years, this scenario predicts the consequences on the network. The deferred maintenance will slightly increase from $2.1 million to $2.3 million and the overall PCI will decrease to 72 by 2028.

This scenario determines the impacts of the City’s existing funding of $345,000 per year for the next 10 years. The results indicate that the network PCI will decrease to 72 by 2028 and approximately two-thirds of the network will be in “Good/Very Good” condition. The deferred maintenance will fluctuate between $1.8 million to $2.3 million and the projected remaining service life (RSL) is 19 years (see Table 4 and Figure 7). Appendix D provides a list of candidate sections selected for treatment in Scenario 1.

Scenario 2: Maintain PCI at 78 ($4.9 million/10 Years)
This scenario aims to maintain the overall pavement network PCI at 78 over the next ten years. To maintain the current PCI at 78, the City would need an average budget of $490,000 per year. The deferred maintenance will decrease to $300,000 by 2028.

In order to maintain the pavement condition at existing conditions (i.e., PCI=78), a total of $4.9 million over the next ten years is required. Approximately 70.8 percent of the network will be in the “Good/Very Good” condition, and there will be no streets in the “Poor” or “Very Poor/Failed” Condition Category. The deferred maintenance will decrease to $300,000, and the projected remaining service life (RSL) will be 22 years (see Table 4 and Figure 8).

Scenario 3: Funding required to reach Best Management Practice ($5.9 million/10 Years) 
The optimal scenario is to bring all pavements into a state of good repair so that best management practices (BMP) can prevail. This scenario would improve the network PCI to 80 and eliminate the deferred maintenance by 2028. This requires an average of $588,000 per year over the next 10 years.

In order to reach a pavement condition where best management practices can be applied, $5.9 million over the next ten years is required. The PCI will reach 80 and the deferred maintenance will be eliminated by 2028 (Figure 9). Approximately, 80 percent of the network will be in “Good/Very Good” condition with 20 percent in the “Fair” condition category. No streets will be in poor or very poor condition categories. The remaining service life (RSL) will be 23 years. Table 6 and Figure 9 below summarize the results.

Note: The term “deferred maintenance” consists of pavement maintenance that is needed but cannot be performed due to lack of funding. Shrinking budgets have forced many cities and counties to defer much needed pavement maintenance. By deferring maintenance, not only does the frequency of citizens' complaints about the condition of the network increase, but the cost to repair these streets rises as well.
