<br /> comprehensive program, which does both It takes care of the best streets first
<br /> (maintenance) and repair the streets beyond a small level of maintenance, with a higher
<br /> dollar value to correct In order to maintain the level of streets in the City, the investment
<br /> must be to maintain the best first and the worst first The best first program will
<br /> concentrate on the collector and arterial streets (McCaslin, 88th, Dillon, Pine and
<br /> Cherry) The worst first focuses on downtown and some other auxiliary streets that are
<br /> over 20 years old and had minimal attention, but have a good base.
<br /> The City paving program relies on various perspectives to create a final plan including
<br /> computer modeling, annual in person street observations, operations staff input, public
<br /> input, City Council input, periodic surveys, and staff pavement experience The
<br /> computer model is a rough score and set of iterative algorithms that helps steer the
<br /> program at a conceptual long term level Ongoing staff field observations verify the
<br /> computer model and validate if it seems accurate and representative of real world
<br /> conditions City Council sets the desired street level of service and budget.
<br /> If the line is set at an OCI of 55, it will ensure all streets are at a condition of fair, good
<br /> or very good condition. A large number of City streets are in good condition, such as in
<br /> the residential area. Some streets downtown have potholes and are in need of
<br /> reconstruction The bulk of the roadway system is above 55 OCI An arterial pavement
<br /> will be rehabbed every 10 to 15 years, depending on the winter and the amount of
<br /> traffic. Typically 10 points will be lost every year for the first ten years and afterwards
<br /> 15 to 20 points will be lost for every one year Every 3 to 5 years staff will complete an
<br /> assessment to redefine the curve to reflect real world conditions. If necessary, the curve
<br /> will be redefined to reflect the actual deterioration Residential streets carry a lot less
<br /> heavy traffic and 10 points will be lost every year Residential streets will be assessed
<br /> and rehabbed every 15 to 25 years, depending on the road condition There is a sense
<br /> of less urgency In terms of budgeting, the cost of paving each segment is calculated
