City launches limited traffic‑calming pilot for Meadowbrook, South Johnson and Hillcrest
Summary
Staff proposed a low‑cost traffic‑calming pilot — temporary surface-mounted rumble strips, upgraded radar speed signs and PD speed trailers — for three residential streets after a data screen showed none strictly qualified for permanent measures but neighborhood safety concerns persist.
The board approved staff moving forward with a limited traffic‑calming pilot after a data‑driven screening and discussion of neighborhood safety.
Jason, who presented the program, described a nine‑step traffic‑calming process that screens streets by average daily traffic, crash history and the percentage of vehicles traveling at least 10 mph over the posted limit. He summarized study results for three candidate streets: South Johnson (approximately 1,000 ADT; 0.2% of traffic over the threshold), Meadowbrook (approximately 220 ADT; about 3% over, and adjacent to a school) and Hillcrest (about 400 ADT and the highest percent traveling 10+ mph over). Jason said that, strictly by the screening criteria, none of the streets fully qualified for permanent physical measures, but the pilot will test low‑cost, reversible devices.
"It's a pilot program," Jason said. "I'm going to get them up there, give about 3 months and see if these things have decreased those numbers that I showed you earlier." The pilot will place temporary surface‑mounted rumble strips, upgraded radar speed signs that display driver speed, and PD speed‑trailer deployments at selected locations for a period of evaluation. If numbers do not improve, staff said it will return with options for more substantial measures, neighborhood engagement and cost estimates for permanent installations.
Commissioners emphasized the need for unobtrusive speed measurement (so data are not skewed by visible enforcement) and requested neighborhood meetings before any permanent action. Staff also noted concurrent sidewalk and ADA projects around Meadowbrook and Johnson that will improve walkability around the school.
What’s next: staff will coordinate with PD, public works and neighborhoods to install temporary devices, collect three months of post‑installation data, and report back to the commission with evaluation results and recommendations.
