Pavement Condition

Pavement Condition Index (PCI)

What is PCI?

Pavement Condition Index, or PCI, is a numerical index between 0 and 100, which is used to indicate the condition of a specific section of road pavement. Note that PCI does not apply to dirt and gravel roads.

Pavement Inspections

PCI is determined by a manual inspection process, done on site by professional pavement inspectors. Inspectors score a section of roadway by conducting a detailed examination of pavement features such as cracking and potholes.

Local roads make up the majority of the County's road system. These are in poor condition, and bring down the system-wide average PCI.

Major Collector and Arterial roads have been kept in better condition. These see higher usage, and therefore receive more funding for pavement maintenance.
