• What are pavement conditions statewide? • How much will it cost to maintain pavements?
Bridges? Essential components? • What is the funding shortfall? • What is impact of different funding scenarios?
Study Objectives
Local Streets Huge Part of State Network
81% of California’s pavements are owned by cities and counties!

Average Statewide PCI
67.8 (2008)
65.8 (2012)68 (Cities)62 (Counties)
Statewide Average PCI = 66
This doesn’t look too bad …
So Why is 66 Critical?
Statewide Trends

Pavement Condition Index
2012
87% of counties have average
rating of “at risk” or “poor”

Sustainable Practices
Recycling technologies
If just 50% of eligible projects use recycled
materials, we can save $8.8 billion!

Bridges
Who Owns Bridges? National Bridge Inventory• 11,863 bridges
• 6,300 are on-system• 5,584 off-system
Non-NBI bridgesApprox. 3,500
Bridges Are Getting Old
55% require rehabilitation
or replacement
It’s Not Just Roads and Bridges
• Sidewalks• Curb ramps• Curb & gutter• Storm drains
• Street lights• Signs• Retaining walls

Pavement Funding Scenarios
1. Existing funding ($1.33 billion/year)2. Transportation CA measure ($1B/yr)
a. Bond i.e. $4.23 billion/year for first 5 years, $1.33 billion for next 5 years
b. No bond i.e. $2.33 billion/year
3. Maintain current PCI at 664. Efficiency scenario5. Best mgmt practices

The percent of roads in failed
condition will increase from 6.6% to
25% by 2022 under current funding.

What’s “failed” condition?
Average Sufficiency Rating
Existing budget will result in SR = 75
Percent Structurally Deficient
Existing budget will result in 38% structurally deficient
bridges.

Conclusions
• Transportation system is not great and it’s not getting better– 25% of roads will be failed in 10 years– 38% of bridges will be structurally deficient
• Additional funding required to hold infrastructure together
• Deferring repairs will cost much more later!
Conclusions
• Delays in funding will cost
