Transportation and Public Works is now Sonoma Public Infrastructure - Website updates coming soon!
What We Do
Maintenance crews work every day to keep County roads safe and passable. This entails constant work, including repairing damaged pavement, cleaning and repairing signs, cleaning drainage channels, mowing grass and removing vegetation, removing landslides, as well as responding to public complaints and requests.
Call to Report Hazards
As our crews cannot monitor the entire road system simultaneously, we encourage citizens to report hazardous conditions whenever they are seen. This helps us respond to incidents as quickly as possible.
Reporting a Dangerous Situation
To report a dangerous situation, such as a tree down across a road or a road inundated with water, please call us right away:
During Business Hours:
Road Maintenance at (707) 565-5100 .
During Off Hours:
Sheriff's Office at (707) 565-2121 .
You can report non-emergency road issues (such as potholes, broken signs, overgrown vegetation, etc.) using SoCo Connect, Sonoma County's application for submitting service requests. SoCo Connect allows County of Sonoma residents, businesses and visitors the ability to report and track non-emergency issues in the unincorporated areas of Sonoma County 24-hours a day, 7 days a week.
To report issues in areas not serviced by the County of Sonoma, please contact the appropriate Local Government Agency.
Keeping Stormwater Clean
Sonoma County is required by the State Water Quality Board and US Environmental Protection Agency to report pollution in stormwater channels. Businesses and individuals are responsible for illicit discharge to the storm drain system. If you notice discharge into a local stream or municipal storm drain, please contact us.
