The California Statewide Local Streets and Roads Needs Assessment (October 2014) In now availble. This report details the failing of California’s streets and roads. It provides a critical analysis and information on local transportation networks' condition. Sonoma County ranks 47th of the 58 counties in California based on the Pavement Condition Index (PCI), which is an improvement from two years ago when we were 51st. See pages 16-17. If voters approve a sales tax increase for roads in June 2015 Sonoma County will greatly improve in the coming years.

Ever wonder how bad your road is? Now you can find out the official Pavement Condition Index (PCI) of your road. This is a measure of road condition on a scale from 1 to 100, with 100 being perfect. Below 30 is considered "failing" and between 31-50 "poor". 74 percent of Sonoma County roads are considered poor or failing. 

This report rates the condition of all the 1,370 miles of road in Sonoma County. It was conducted by consultants hired by the county Department of Transportation and Public Works (DTPW). The survey was conducted in 2012 and 2013 and the report was released in the spring of 2014.

The roads are listed alphabetically A-Z beginning on page 24. The first part of the report provides an interesting overview of pavement conditions and describes the methodology for the survey.

The report lists the road segments evaluated for each road, the PCI rating and estimate of remaining life of the road. As you might expect, many of the roads have zero remaining life.

As the board of supervisors move towards implementing the Long-Term Road Plan, the data in this report will be usefull to community groups who are organizing their neighborhoods to bring attention to their failed roads. If you would like more information on how to organize your neighborhood, see

Click here to read the ordinance that the supervisors will consider on Tuesday, August 5, at about 9:00 am that will formally place a ¼ cent sales tax on the November ballot. It includes an advisory measure that will be on the same ballot that will ask for approval of the proposed distribution of the revenue from the increase in sales tax. 

Here is the proposed funding plan for the Long-Term Road Plan adopted by the Board of Supervisors in June. 
The centerpiece is a 1/4 cent county-wide sales tax increase for 20 years that will generate about $8.7 million per year for the county to use on pavement preservation. 
In addition, the nine cities in Sonoma County would receive about $11 million per year for badly needed street repairs. (Santa Rosa would get approximately $5.5 million per year and Petaluma $1.9 million). A maintenance of effort provision would require the county and the cities to maintain their current levels of general funds for roads. 
This means that the county would be committed to sustaining the $8.0 million from the general fund and $2.2 million from the refuse franchise fees for a total of $10.2 from the general fund each year for pavement preservation.
SOSroads congratulates the supervisors for continuing to commit $5.4 million for road maintenance and as well as $10.2 million for pavement preservation from the general fund each year.
Those funds, together with $1.8 in federal funds and the new sales tax revenue would make over $20 million available each year for pavement preservation (Summary, p. 4). 
SOSroads thinks the proposed plan is a major step forward, but we have three concerns.
First, some want to divert funds from rehabilitating roads to transit projects. Given the dire condition of the county road system, we think this would be a mistake and sends a confusing message to voters.
Second, we think the general fund commitment should be indexed to inflation.  The failure to index road repair and maintenance funds to inflation is a major cause of our current problems.
Third, we have advocated for a 10 year plan, given too much can change over 20. We hope there might be ways of front-loading some of this work before the roads deteriorate further and are more expensive to rehabilitate.

The Metropolitan Transportation Commission (MTC) is producing a series of videos on the deteriorating conditions of streets and roads in the nine county Bay Area. This video features one of Sonoma County's worst roads, Sonoma Mountain Road.
MTC is going to use the videos in an effort to convince legislators in Sacramento to make more funding available to repair rapidly declining roads.

The Board of Supervisors will meet Tuesday March 25, 2014 to vote on a list of roads for repair and pavement preservation. Plan on attending to voice your opinion on county road conditions.
