This chart provides detail of the current cost for treatment of the entire improved system excluding
<br />concrete streets at the end of the 2010 rating period. The total estimated treatment cost backlog at the
<br />end of 2010 is $139,021,000.

<br />Using the PMS software, an analysis for a 10-year period (2011 through 2020) has been completed
<br />based on the current funding. The PMS software evaluates the deterioration of each segment based on
<br />individual OCI ratings. The software then projects when to apply the necessary treatment at the
<br />proper time. When possible, the system applies a less expensive treatment earlier in the degradation
<br />curve. In the following four graphs this projected evaluation has been shown with historical data to
<br />present a more comprehensive view of the street system. The graphs show the impact of past and
<br />percentage
<br />current funding over a 20-year period (2001 to 2020). Each graph indicates the of streets
<br />which 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. Graphs
<br />from previous years, which focused on funding scenarios without differentiating between the
<br />treatment types, are not included in this report.
