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 .

Our Streets & Roads

Morgan Hill
256
Lane-miles of paved roads ( 126.9 centerline miles )*
67
Current average Pavement Condition Index ( PCI )
70 or higher
Morgan Hill ’ s ( unofficial ) goal for average PCI
$ 1,086,000
Six-year average funding level for pavement maintenance
$ 25 million
Current backlog of deferred maintenance
$ 4.5 million
Additional annual funding needed to gradually increase PCI and reduce backlog
Gilroy
264
Lane-miles of paved roads ( 120 centerline miles )*
66
Current average Pavement Condition Index ( PCI )
70
Gilroy ’ s goal for average PCI
$ 300,000
Current annual funding level for pavement maintenance
$ 10 million
Current backlog of deferred maintenance
$ 2.2 million
Annual funding shortfall
* Centerline miles = road length from start to end point . Lane-miles = centerline length multiplied by number of lanes .
