Committee weighs removing speed humps, testing speed tables in Tanyard Springs

Public Works told the Transportation Advisory Committee that measured hump profiles in Tanyard Springs are borderline with some readings near the policy threshold, and staff requested direction on whether to pilot alternative devices.

"They're they're at the 3 inch mark...There's some that's a little shy of this 2 and 3 quarter," Public Works staff said, summarizing field measurements. Gerald Bolden of Cordino Group explained options: speed tables tend to reduce average speeds only 1–3 mph compared with existing humps, while the current humps can reduce speeds to about 10–15 mph when crossed.

Committee members raised concerns about accessibility and emergency access. Bolden said the street’s narrow width, closely spaced driveways and parked cars limit horizontal-deflection options and that Fire/EMS historically opposed measures that could create one-way sections. He emphasized coordination: "we'll have to coordinate with emergency services...to make sure we're not creating a situation for them that reduces response time."

Members discussed a data-driven pilot. Public Works proposed collecting pre-change speed data, removing the humps for a trial period (staff suggested about two weeks) to observe any increase in travel speeds, then installing and evaluating speed tables or other devices. "I would recommend...get some pre...data which is what's in the field currently," Bolden said.

Several committee members and a citizen commenter asked for adherence to standards and noted that devices should balance speed reduction with accessibility. The committee asked staff to develop the pilot plan, collect baseline data, coordinate with emergency services and return with findings and costs.

The committee did not authorize construction at this meeting; members instructed staff to run a short test and report results for a follow-up decision.
