How much should we be spending on streets pavement preservation?

• Based off our past historical averages combined with increases - $2,300,000 - $3,600,000

  • Residential Preventative Maintenance (1995 – 2005)
    • Pavement Preventative Maintenance 10 yr average spending is $470,865.
    • Concrete Replacement 10 year average is $200,000.
    • $670,865 has increased to $913,043 (36% Increase) by the Construction Cost Index.
    • 2006 approved budget was $400,000 for overlay and concrete replacement.
  • Arterial, Collector, and Intersections
    • $1,000,000 - $2,000,000 per year dependent on the year.
    • $1,360,000 - $2,720,000 with 36% increase.

• Based upon research studies - $2,400,000 (preservation only no capacity improvements)

  • “Life Cycle Evaluation of Flexible Pavement Preventative Maintenance”, ASCE, Journal of Transportation Engineering
    • Concludes that $10,000 per lane mile is an optimal number where cost and benefit is maximized.
  • Approximately 240 lane miles = $2,400,000 amount of PM dollars annually should be spent.

• Based upon our Audit Reporting - $2,600,000 (preservation only no capacity improvements)

  • $205,096,621 total system replacement cost.
  • Assumption of an average pavement life cycle of 20 years and pm & rehab costs are ¼ the cost of complete replacement cost.
