The Public Works Operations and Maintenance Performance Standards is a structured system to set attainable goals for inspecting and maintaining all public works infrastructure. Asset defects, for example, potholes, are noted and prioritized for repair based on risk and severity and scheduled for completion per stated repair time frames in the performance standards. In addition to the internal inspection and reporting system, the program will continue to be supplemented by customer service requests (CSR’s). CSR’s are an important part of the reporting system and all CSR’s will receive an immediate notification response and an estimated repair timeline response within 3 days.
Although Public Works staff shall make every effort to meet the Operations and Maintenance Performance Standards goals, there will be times when seasonal conditions, unsuitable weather, or other factors limit the ability to meet the desired repair timelines.

Public Works Pavement Management System
The Public Works Pavement Management System ( pdf Pavement Management System(488 KB) ) is a hybrid system of traditional Pavement Condition Index (PCI) evaluations and leading-edge data collection and calculation software. PCI ratings are updated in the condition assessment database, and new ratings are created yearly. The Pavement Management System then weights the condition rating with the street classification pdf Transportation Street Classification(1.13 MB) and street population density, on Truro streets resulting in weighted PCI ratings.
This often results in streets with higher classification and population density having a higher priority than lower classification and population density streets with worse conditions, as the higher classification and population density streets have higher traffic volumes and condition will degrade much faster.
Town of Truro Street Ratings and Capital Budget
The pdf Town of Truro Street Ratings(301 KB) is a compilation of the Weighted PCI ratings sorted from lowest PCI (worst condition) to highest PCI (best condition). Each year the PCI ratings are updated in the Pavement Management System and new ratings are created, which are then used to assist with the street capital budget process.
The Street Ratings guide in the capital budget process, along with other factors that need to be considered. Other factors include the type of asphalt defect requiring repair, the sub-base condition of each street, the condition of underground infrastructure (water, sanitary, and storm sewers) on each street, the curb and sidewalk condition on the street, annual degradation of PCI, operational capacity, and budget availability to determine annual budget priority and rehabilitation options for each street.
There are two types of construction for street rehabilitation: overlay and rebuild. An overlay typically consists of milling the existing asphalt and placing new asphalt over the entire street. The catch basins, manholes, and water valves are adjusted to the height of the new asphalt. Minor sidewalk and curb reconstruction are often completed in an overlay project as well. A rebuild project typically includes the removal of all existing asphalt on the street to the gravel subbase, replacement and/or installation of underground infrastructure, complete replacement of curb and sidewalk.
Each year, the Town makes a significant investment in capital replacements of our public works infrastructure (streets, curbs, sidewalks, water lines and sewer systems). To obtain the best value for the capital budget, many other factors are also considered, along with the street ratings, to determine which streets are paved each year.
