VDOT briefs Campbell County on traffic-calming process; Sherbrooke falls short of intrusive‑measure threshold

VDOT staff walked the Campbell County board through the state traffic‑calming program and local data for Sherbrooke and Rainbow Forest, explaining eligibility rules, community‑support thresholds and lower‑cost alternatives the county can deploy without full traffic‑calming designation.

Jerry Carter, a VDOT engineer presenting the program, said the traffic‑calming process is eight steps and that the chief eligibility conditions are (1) the road must be a local residential road with a posted limit of 25 mph or less, and (2) the 85th‑percentile operating speed must be at least 10 mph above the posted limit. "Lowering speeds. Again, lowering speeds is critical to enhancing safety," Carter said while describing the program’s goals.

VDOT presented local speed counts that show Sherbrooke Drive and Lighthouse Drive carry roughly 1,200 vehicles per day; measured 85th‑percentile speeds were about 34 mph on the study segment, which the presenters said does not meet the 10‑mph‑over threshold required to qualify for intrusive measures such as speed tables. By contrast, Rainbow Forest met the program threshold on the counts VDOT took and could qualify for traffic‑calming under the guidance.

VDOT explained the public‑support test: an initial engagement (10 residents or 10% of addresses) is used to trigger a formal engineering study; if intrusive measures are proposed, the county must show 50% approval from affected addresses before moving forward. VDOT staff noted lower‑cost, non‑intrusive options such as speed display signs (ballpark installed cost $4–6k), targeted enforcement, and temporary land‑use permits to place signs on state right of way while the formal process proceeds.

Funding and long‑term maintenance were discussed: VDOT said eligible construction can sometimes be paid from local secondary road (telecom) funds or other local sources, but long‑term maintenance responsibilities vary depending on whether the devices are integrated into the roadway or are stand‑alone signs. The presenters also summarized candidate 'smart‑scale' projects in county planning (passing lanes on Route 501; safety improvements on US‑29; Timberlake Road; Candler's Mountain improvements) and flagged the Rustburg High School entrance as an area under active review after recent near‑misses.

Next steps and requests - VDOT offered to perform counts and additional studies on request and said staff will work with the county on lower‑cost deployments while helping neighborhoods pursue formal traffic‑calming where they meet thresholds. - Board members asked the sheriff’s office to provide enforcement data; VDOT and county staff said directed enforcement patrols are already being used and that the sheriff’s office will provide historical ticket counts where available.

VDOT emphasized caution about changing speed limits or installing intrusive measures without broad neighborhood support and a complete engineering record. The agency urged starting with less intrusive measures and thorough public engagement before committing to permanent, higher‑cost interventions.
