Board of Supervisors approves list of SB1 infrastructure projects for 2025-26 fiscal year

The Sonoma County Board of Supervisors today approved a list of local streets and road projects to be completed during the 2025-26 construction seasons using more than $14.5 million in anticipated revenue from SB1, the Road Repair and Accountability Act. The state’s SB1 Road Maintenance and Rehabilitation Account is derived primarily from per-gallon fuel excise taxes. All SB1 funds go to infrastructure repair and improvement projects, in alignment with the Resilient Infrastructure pillar of Sonoma County’s Five-year Strategic Plan. 

“This crucial public investment allows County road crews to repair and pave more secondary roads and rural roads, resulting in more overall road miles being maintained on an annual basis,” said Supervisor Lynda Hopkins, chair of the Board of Supervisors. “State law requires SB1 funds to be used on the most high-priority and cost-effective projects that also meet community priorities.” 

SB1 was signed into law in 2017 and contributes to the design, construction, management and equipment required for basic road maintenance, rehabilitation, and critical safety needs that improve and extend the useful life of the county road system. Eligible projects include culvert installation, road striping and stenciling, vegetation management, bridge construction and road paving.  

Sonoma County has 1,368 miles of roads and 328 bridges, which is the largest road network in the San Francisco Bay Area. The selection process for road projects is based on a two-year budget cycle and takes multiple criteria into consideration, including pavement condition, type and amount of usage, design characteristics, and geographic location within the county. 

State gas tax revenue from SB1 is distributed based on the number of vehicle registrations in a particular county, rather than the number of road miles, so rural counties receive disproportionately less road funding. Other funding sources for county road repairs include contributions from the county’s General Fund, PG&E settlement funds, Measure L transient occupancy tax and Measure M sales tax.  

In 2012, the Sonoma County Board of Supervisors began using General Funds to bolster pavement preservation efforts and today contributes more to road repairs than any other California county.   

A summary report for today’s Board item, including the resolution and a full list of approved roads and equipment, is available.
