It is recommended that the Citizen's Oversight Committee receive an update from staff on the Public Works Department's Five-Year Paving Plan.
Body
BACKGROUND/DISCUSSION
The South San Francisco community identified street maintenance as high priority in feedback related to Measure W. The City is planning for $19 million in street maintenance repairs with funding from Measure W and other transportation-related funding sources.
The City is responsible for the maintenance and repair of approximately 138 centerline miles, comprised of 33 arterial miles, 38 collector miles, and 67 residential miles.

The PMP also recommends optimal maintenance and rehabilitation strategies for a given year with a certain budget.
The PMP provides:
* A multi-year road rehabilitation and maintenance program;
* A preventative maintenance program for a desired PCI; and
* Identification of cost-effective repairs for a certain budget.

Typically, a newly constructed road would have a PCI of 100 and an older failed road would have a PCI of 25 or less. In a recent PMP network survey, the average PCI of the entire roadway network to the City of South San Francisco is 76, which i...
