Pre-2006 Pavement Management

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)
