Public Works staff are constantly maintaining, constructing, and improving our transportation infrastructure; although State Route 29 is not a City facility, we are constantly developing new ways to improve traffic flow through the City in coordination with CalTrans. We maintain streets, the storm drain system, street lights, and traffic signals.
If your concern involves an immediate threat to life or safety please dial 911.
Traffic signal timing, missing signs, streetlight outages, potholes, roadway debris, and other maintenance concerns can be reported online or by calling (707) 647-4550.
