• 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
![Page 5: Pavement Management Systems -- Bay Area Perspective](https://reader034.fdocuments.us/reader034/viewer/2022042817/55a6a2821a28ab27578b4844/html5/thumbnails/5.jpg)
Average Pavement Condition Index
68 (2008)
66 (2014)

Statewide Average PCI = 66
This doesn’t look too bad…

PCI Trends
54 counties have average PCI that is “at risk” or “poor”

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
![Page 13: Pavement Management Systems -- Bay Area Perspective](https://reader034.fdocuments.us/reader034/viewer/2022042817/55a6a2821a28ab27578b4844/html5/thumbnails/13.jpg)
Unpaved Roads
• 4.4 % of total network – gravel & dirt
• Mostly rural counties
• 9,801 miles
• $960 million in needs

Existing Funding
We only have $1.66 B/year ….
![Page 16: Pavement Management Systems -- Bay Area Perspective](https://reader034.fdocuments.us/reader034/viewer/2022042817/55a6a2821a28ab27578b4844/html5/thumbnails/16.jpg)
Maintain PCI = 66
We need $3.3 B/year!
![Page 17: Pavement Management Systems -- Bay Area Perspective](https://reader034.fdocuments.us/reader034/viewer/2022042817/55a6a2821a28ab27578b4844/html5/thumbnails/17.jpg)
Reach Best Mgmt Practices
We need $7.3 B/year!
![Page 18: Pavement Management Systems -- Bay Area Perspective](https://reader034.fdocuments.us/reader034/viewer/2022042817/55a6a2821a28ab27578b4844/html5/thumbnails/18.jpg)
What Is a Failed Road?
The percent of roads in failedcondition will increase from 6.2% to almost 25% by 2024
under current funding
![Page 19: Pavement Management Systems -- Bay Area Perspective](https://reader034.fdocuments.us/reader034/viewer/2022042817/55a6a2821a28ab27578b4844/html5/thumbnails/19.jpg)
Local Bridges
![Page 20: Pavement Management Systems -- Bay Area Perspective](https://reader034.fdocuments.us/reader034/viewer/2022042817/55a6a2821a28ab27578b4844/html5/thumbnails/20.jpg)
Who Owns Bridges?
• 50% of California’s bridges are owned by cities & counties
• NBI (11,863 bridges)• Non-NBI bridges
(3500)
![Page 21: Pavement Management Systems -- Bay Area Perspective](https://reader034.fdocuments.us/reader034/viewer/2022042817/55a6a2821a28ab27578b4844/html5/thumbnails/21.jpg)
Bridges Are Getting Old
55% require rehabilitation or
replacement
![Page 22: Pavement Management Systems -- Bay Area Perspective](https://reader034.fdocuments.us/reader034/viewer/2022042817/55a6a2821a28ab27578b4844/html5/thumbnails/22.jpg)
Structurally Deficient Bridges
33% will be structurally
deficient with existing level of
funding
![Page 23: Pavement Management Systems -- Bay Area Perspective](https://reader034.fdocuments.us/reader034/viewer/2022042817/55a6a2821a28ab27578b4844/html5/thumbnails/23.jpg)
It’s Not Just Roads and Bridges
• Street lights
• Signs
• Retaining walls
• Sidewalks• Curb ramps• Curb &
gutter• Storm drains

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%

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
