Engineering Criteria Used to Rate Projects

• ADT (Average Daily Traffic)
• Condition of Roadway
• Classification of Roads
• Remaining Service Life (RSL)
• Drainage
• Safety

14
Additional Factors Considered

• Equitable Distribution Evaluation
• Economic Impact Evaluation

15
Explanation of Evaluations

• Engineering Evaluation consists of the criteria
  outlined in the previous slide (ADT, RSL, etc.)
• Equitable Distribution consists of dividing the
  County up geographically and identifying
  prioritized roads within those geographical
  areas.
• Economic Impact consists of identifying roads in
  areas of high commercial activity within the
  County (the primary concentration is within the
  Pagosa Lakes area).

Why Pavement?

• !!!!!
• By investing money now, it precludes the
  necessity to rebuild at a much higher cost
• Consensus of the Public Works Staff
• Protects existing investments
