• What are pavement conditions statewide?

• How much will it cost to maintain roads? Bridges? Essential components?

• What is the funding shortfall?

• What are impacts of different funding scenarios?

Local Roads Are A Huge Part of California’s Network

More than 80% of California’s roads are

owned by cities & counties!

Pavements

Average Pavement Condition Index

68 (2008)

66 (2014)

Statewide Average PCI = 66

This doesn’t look too bad…

So Why is 66 Critical?

PCI Trends

Complete Streets Policies

• Primarily bike and pedestrian facilities

• 28% of total agencies have a complete streets policy (triple the number from 2012)

• 21% have elements of policy in place

• Large range in costs - $15/sy to $700/sy

Unpaved Roads

• 4.4 % of total network – gravel & dirt

• Mostly rural counties

• 9,801 miles

• $960 million in needs

Funding Strategies for Pavements

RTPA

RCTF

Existing Funding

We only have $1.66 B/year ….

Maintain PCI = 66

We need $3.3 B/year!

Reach Best Mgmt Practices

We need $7.3 B/year!

What Is a Failed Road?

The percent of roads in failedcondition will increase from 6.2% to almost 25% by 2024

under current funding

Local Bridges

Who Owns Bridges?

• 50% of California’s bridges are owned by cities & counties

• NBI (11,863 bridges)• Non-NBI bridges

(3500)

Bridges Are Getting Old

55% require rehabilitation or

replacement

Structurally Deficient Bridges

33% will be structurally

deficient with existing level of

funding

It’s Not Just Roads and Bridges

• Street lights

• Signs

• Retaining walls

• Sidewalks• Curb ramps• Curb &

gutter• Storm drains

What Are Funding Shortfalls?

Sources of Funding

• State funding is 54% of the total, and it’s almost all gas tax

• Local funding is about 34%• Federal funding is about 13%

Potential Funding Solutions

($M/year)

New technologies to stretch existing dollars $ 912

Restore gas tax to 1994 levels $ 1,700

Index gas tax to CPI (2%) $ 48

Raise gas tax by 10 cents/gallon $ 1,330

Return weight based fees $ 950

Mile-based fee (SB 1077) Unknown

Additional Local Sales Tax Measures (15 counties)

$300

Findings

• Local road network is deteriorating, and by 2024:• Average PCI will deteriorate from 66 to 55

• Unfunded backlog will grow to from $40 to $61 billion

• Almost 25% of roads will be in failed condition

• Similar conclusions for bridges, safety and other essential transportation components

• An additional $7.8 billion/year is needed

Conclusions

• Californians and our economy relies on the local transportation system

• New sustainable sources of revenues must be created that are focused on preservation of existing local road network

• Californians need to work together to find ways to fund local streets & roads
