Pavement Condition Index( PCI)
The way it pencils out, according to Morgan Hill and Gilroy city officials, the most cost-efficient scenario is to maintain our local roads at a PCI of 70 or better. If we ignore the roads, deferred maintenance costs will rise faster than PCI values fall. The more we delay, the more we pay.

* Centerline miles = road length from start to end point. Lane-miles = centerline length multiplied by number of lanes.
