Public Works has completed a pavement condition assessment of all of the public streets within the city.
The assessment serves two primary purposes:
1. To provide an objective evaluation of the condition of the city’s pavement infrastructure and provide the
baseline for future maintenance and management of that infrastructure.
2. To provide a complete inventory of pavement area by street with replacement costs and remaining service life.
This information is being used by the city’s Finance department for asset reporting in the city’s financial
reports.
The assessment, conducted by IMS Infrastructure Management Services, consisted of surveys of each roadway segment to measure roughness, rut depth and crack condition. The data collected was used to develop a pavement condition index (PCI) ranging from 0 to 100 for each roadway segment. The overview report attached summarizes the methodology and provides a list of roads with corresponding PCI numbers.
Significant findings of the report include:
- The city has 185 centerline miles of roadway with a replacement cost value of $216 million.
- Although the overall condition of the city’s pavement is described as “fair”, the majority of the city’s pavement
is at a point where it is beginning to deteriorate at an accelerated rate due to its age and lack of maintenance.
- Approximately $2 million per year is needed to maintain the current condition of the overall road system.
- Currently, there is a 13% backlog of roads in “poor” condition. Even at a funding level of $2 million per
year this backlog will remain and may even grow slightly in the first 5 years of the pavement management
program.
Public Works anticipates having approximately $750,000 available for resurfacing in 2010. Based on the results of the pavement condition assessment, the city would need to move towards an annual funding level of $2.5 to $3 million in order to improve the overall condition of the system.
