Galt council directs staff to pursue speed-control measures on Adairway and develop citywide policy

The Galt City Council voted 5-0 on July 1 to direct staff to pursue a package of traffic-control measures on Adairway — including multiple speed-control devices and an entrance island — and to return with a draft speed-control policy for the city.

Public Works Director Griffin opened the discussion by reviewing options and describing three primary device types: "speed humps, speed lumps, [and] speed tables," and presented a staff draft modeled on Elk Grove's neighborhood-driven process.

The council and staff emphasized that the draft program would be iterative and community-driven. Griffin said the model includes two steps: a neighborhood petition (staff noted a 75 percent-signature threshold in the draft), followed by technical evaluation and then direct outreach to the properties that would be immediately affected. "Step 1 is the neighborhood will get together and submit a formal request," Griffin said. He added that if the local buy-in and engineering analysis indicate a device is appropriate, staff would seek approval to install the device and handle signage, striping and traffic control.

Fire Chief Felipe Rodriguez said he favored designs with gaps that allow emergency vehicles to pass and recommended 8-foot gaps to match fire-engine widths. "We prefer the lumps because they do provide a space for the fire engines to drive through," Rodriguez said, noting that the department does not recommend such devices on collectors or arterials where posted speeds are higher.

Public commenters described experience from other cities and warned of side effects. Ken Lee said improperly installed devices can push drivers onto sidewalks or other streets, and residents living next to humps can feel vibrations inside their homes. Chris Brostman urged caution about adopting a high signature threshold; he called the 75 percent figure "unobtainable" in some neighborhoods.

Council members asked staff to make sure noninfrastructural interventions were tried or considered and requested clear technical thresholds for when a street becomes eligible for the program (for example, how speed and volume data would be used to qualify a street). Police and fire also urged that enforcement and temporary measures (radar trailers, extra patrols) be part of the toolkit before permanent devices are installed.

After discussion the council directed staff to move forward on Adairway specifically with the combination of measures Griffin identified (the staff exhibit showed 4–5 proposed speed lumps in the neighborhood, plus the entrance island and striping continuity), and to apply the draft community process for implementation on that corridor while staff finalizes a citywide policy. The motion included follow-up outreach to affected properties to confirm buy-in under the draft thresholds and to return with an implementation plan and cost estimate. The motion passed 5-0.

Staff estimated the installation cost for a set of speed-control devices (including striping and signage) at roughly $15,000–$18,000 per device; a program combining multiple devices and striping could range from about $60,000 up to roughly $170,000 depending on scope and options.

Next steps: staff will proceed with neighborhood outreach on Adairway per the draft criteria, coordinate with police and fire on device geometry and emergency access, return with final cost estimates and a draft citywide policy that documents eligibility criteria, technical thresholds and an appeals path for council review.
