Current Treatment Costs
<br />This chart provides detail of the current cost for treatment of the entire improved system excluding
<br />concrete streets at the end of the 2012 rating period. The total estimated treatment cost backlog at the
<br />end of 2012 is $100 million down from $118 million reported in 2011.

<br />Historical and Projected Funding Outcomes
<br />Using the PMS software, an analysis for a 10 -year period (2013 through 2022) has been completed
<br />based on the current funding, including the 2012 bond measure. The PMS software evaluates the
<br />deterioration of each segment based on individual OCI ratings. The software then projects when to
<br />apply the necessary treatment at the proper time. When possible, the system applies a less expensive
<br />treatment earlier in the degradation curve to prevent the street from falling into an overlay or
<br />reconstruct range. In the following four graphs this projected evaluation includes historical data to
<br />present a more comprehensive view of the street system. The graphs show the impact of past and
<br />current funding over a 20 -year period (2002 to 2022). Each graph indicates the percentage of streets
<br />that fall within a specific treatment range (reconstruct, overlay and no treatment). Plotting the
<br />percentages of streets within a treatment range over time visually demonstrates the overall condition
<br />of streets within that class. This is useful when deciding how to allocate funds in future years.
