Road Improvements and SB1

Published:  April 17, 2018

On April 17th, 2018, the Sonoma County Board of Supervisors approved a list of road improvement projects which will make it easier and safer to travel in Sonoma County. These improvements will be funded with the new State gas tax, also known as Senate Bill 1 (SB 1), the Road Repair and Accountability Act of 2017.

The improvements include over 15 miles of resurfaced roads, 12 miles of ditching, 13 culvert replacements, and two viaduct replacements. These projects are budgeted with the $9.8 million in new gas tax funding that County of Sonoma is projected to receive in Fiscal Year 2018-19.

The projects include:

The new gas tax comes with transparency and accountability: transportation agencies must submit project lists like the one approved today to the State in order to receive funding. This ensures that the $5 billion each year generated from the new state gas tax is dedicated wisely.
