Corte Madera BPAC tentatively backs advisory radar speed signs but notes limits on enforcement

BPAC considered a staff proposal to install two solar, radar-based speed-feedback signs on multiuse paths to remind users of appropriate speeds and flash a “slow down” warning when thresholds are exceeded. Staff estimated a purchase cost of roughly $11,000 per sign and explained that posted path speed limits would still require a formal speed study before they become enforceable.

Committee members and the public supported installing advisory signs but cautioned the signs alone cannot fully address safety concerns, particularly those caused by throttle-equipped electric motorcycles that exceed the speed range of normal e-bikes. Members suggested locating one sign along the San Clemente Bay Trail corridor near a recent accident and placing the other near the Hart Street connector or the Hart Street/Hard Street connector rather than both on the same stretch of path.

BPAC members emphasized that design-based speed management (optical narrowing with trees, targeted curb treatments and other traffic-calming measures) must accompany signage. Several members also asked staff to pursue enforcement-team briefings and to explore whether nearby jurisdictions’ regulations (Mill Valley and others) or additional policies could help address illegal e-motorcycle use.

Why it matters: Advisory radar signs are lower-cost, immediate measures that provide feedback to path users, but the committee noted their limits without enforcement and complementary engineering changes.

What’s next: Staff will take BPAC input on sign locations to the town and return with a recommendation that includes preferred sites and an estimated implementation timeline.
