Map Information

The above map displays the pavement condition of County-maintained roads, as determined by periodic field inspections. NOTE: Roads that are within city limits, state highways, or private property do not belong to the County-Maintained Road System.

What is PCI?

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