How does DPW select the streets for treatment?

Every two years, we hire a consultant to inspect and rate the condition of every city-maintained roadway.  The consultant then calculates each roadway segment’s “Pavement Condition Index” (PCI).  The PCI for each road is an initial starting point for us to identify roadways to include in upcoming resurfacing projects. PCI values range from 0-100 with 0 being the worst and 100 being a newly resurfaced roadway.

Each winter, our Engineering Division performs a field inspection on approximately 50 roadways using a list developed based on PCI values.  During this field inspection, we determine which resurfacing treatment to implement on each roadway.  Typically, the roadways selected for a field visit include those with a PCI less than 30 (asphalt overlay applications), and between 50 and 70 (micro-surfacing applications).

Once the field inspection is complete, we develop a list of potential roadways to include in its annual resurfacing project based on a number of factors including (but not limited to): budget, location, the number of curb ramps required, number of vehicles and resident that will be served, additional bicycle/pedestrian/transit improvements, and whether utilities have upcoming projects on the same roadway. If a roadway is recommended for resurfacing and a utility company has a planned project on the same roadway, we will typically defer resurfacing of the roadway for 1-2 years in order to allow the utility to perform their work.
