The City of Clive’s Pavement Management, Design Standards and Specifications Study provides guidance for sustainable pavement infrastructure through the use of improved design standards and proper asset management principles and allows the City to ensure, with sufficient funding, that roadways are designed properly, are adequately maintained and rehabilitated, and reconstructed at a high level of service and safety.

The project consisted of:

  • Review of the City’s standards for street construction and maintenance practices, then making recommendations for improvements to achieve long-lasting pavements
  • Developing an inventory of the City’s street system, which consists of 75 centerline miles and 170 lane-miles
  • Evaluating the system’s current roadway conditions
  • Determining major rehabilitation and reconstruction alternatives and the thresholds that will trigger their selection, to be used in the data analysis, condition projections, and their life cycle cost analysis
  • Developing two (2) pavement replacement schedules, one using current design standards and the other utilizing the recommended long-life standards, for all existing and future full build-out streets (presumed to occur by 2035), then comparing the long term costs
  • Using the agreed-upon new design standards, developing sustainable maintenance/replacement schedules with annualized costs and condition projections for the following scenarios:
  • A “Baseline Scenario” with funding that stays the same as it currently exists and continues for the next 100 years
  • “Minimum-Performance-Based Scenarios” that maintain a minimum pavement condition levels based on a pavement condition index (PCI) of either 70, 60, 50, 40, or 30, to aid in determining optimal treatment trigger ranges
  • “Average-Performance-Based Scenarios” that maintain a network-wide average condition of PCI greater than 70, 60, and 50, respectively, to determine achievable performance metrics
  • A “Funding-Based Scenario” with an annual budget that decreases with the elimination of the franchise fee and the resulting future PCI
  • Various Funding Based Scenarios with increased funding levels to determine what the optimal annual budget allocation would be
  • A “Hybrid Performance-Based” Scenario target based on achievable goals for different functional classifications of roads, and within recommended budget parameters.
  • Develop 10-year Capital Improvement Plans (CIPs) with various annual funding amounts to illustrate specific projects that may be completed with each funding scenario
  • With the City Council-determined annual budget amount, prepare a 10-year CIP with annual project selections.
