Drivers throughout Healdsburg during the past week found their attention directed to speed limit signs by red flags, installed at the top of the signs. The flags were nearly ubiquitous, as existing speed limits all over town were adjusted down, in many cases, to conform with lower speeds set by the City Council about a year ago.
In fact, though the attention-getting flags were installed just a few days ago, the speed limits they signal went into effect in July 2025, one year ago. That came after a long process that included two City Council meetings in June 2025, followed by staff-prepared work orders for every speed limit sign in town. The work order process included visiting every location to confirm sight distances and potential conflicts with underground utilities.
“A widespread update like this takes time to implement carefully and effectively,” said Ray Holley, the city’s public information officer.
The signage contractor was engaged in April, the signs and hardware ordered in June. The installation of 87 new or modified speed limit signs, which began on July 1, will continue the rest of the month—at which time, their mission accomplished, the flags will be removed.
An additional 37 signs near local schools that will warn drivers of special speed limits “when children are present” will be installed when they arrive. Speed limits in school zones when children are present will be a 15 mph speed zone within 500 feet of a school and 25 mph between 500-1,000 feet.
The school zones include not only the elementary schools (both public and private) but the middle schools and Healdsburg High as well. As the high school and the Fitch Mountain Campus of the elementary school abut, the area they share along University, Monte Vista, Sanns and neighboring streets is a fairly large zone of school speed reduction.
The changes are tied to safety initiatives like Vision Zero, a collaborative nonprofit campaign that originated in Sweden in 1997 and “operates on the core principle that life and health should never be compromised for speed or convenience.” The Sonoma County Vision Zero project, as well as a county Safe Routes to School campaign, both figured into the staff’s proposed new speed limits.
How fast, how slow?
Notable adjustments in speed limits affecting key routes include Healdsburg Avenue at both the north entrance and the south entrance of town. In both cases, the speed limits are reduced by five miles per hour—the former 40 mph speed limit from the northern city limit to Parkland Farms Boulevard is reduced to 35, and from Parkland Farms into town at Powell Avenue it drops to 30 mph from 35.
Similarly, the south entrance was formerly 45 mph to Bailache and is now 35. The downtown speed limit from Piper to Mill Street is now just 20 mph. The 20 mph limit also applies to other downtown streets, such as Center and Plaza. (Speed limits apply to traffic going in both directions, of course).
The changes, all reductions, are adjustments to what is called the state default “prima facie” speed limit in residential areas of 25 mph. The reasons for the lower speed limits given by the Sonoma County Transportation and Climate Authorities (SCTCA) are, “Lower speeds reduce crash severity, give drivers more time to stop, and improve road visibility.” The lower speed limits also “enable safer street design improvement,” according to the SCTCA.
The City Council approved the new speed zones map on June 2, 2025. The vote was 4-1, with Ron Edwards voting “no.” Before the vote Ariel Kelley gave an impassioned endorsement of the goals of the Vision Zero initiative, which strives to reduce pedestrian fatalities to zero.
“I want to support the recommendations,” she said from the dais. “I feel really strongly that this is one of those things that we have the ability to actually improve people’s ability to get in and around our town, to get out of their cars, should they want to, or just to slow down. Frankly, lives will be saved because of it. That feels like a pretty compelling reason to me.”
