Program• Emergency repairs only• Limited Caltrans maintenance work

on SR 150 and SR33 in city limits• Maintenance staff positions cut• Minimal preventative maintenance

since 2003

Pavement Condition Index (PCI)

• What is it? Computerized quality rating 0-100 0 no structural stability, very deteriorated 100 new street

• How is it calculated? Type and percentage of cracks, thickness of pavement, condition

• City has 147 road segments.• Average PCI Citywide is 48• Other Cities Try to Maintain +/- 65

Current Street Conditions

• 0-20: 21 segments• 21-40: 33 segments• 41-60: 40 segments• 61-80: 39 segments• 81-100: 14 segments

Identifying NeedScheduling Repairs

• Pavement Condition Index (<20)• Traffic Volume (increased volume

= decreased street life)• Truck traffic• 06-07 $400,000 budget (includes

5 years of STP funding)
