How do I get the speed limit changed on my street?
After receiving a request for a speed zone, Public Works staff completes the required Engineering and Traffic Study. The study includes:
• A review of all speed related collisions for a three year period.
• The measurement of existing speeds with a radar meter, using an unmarked vehicle.
• Calculating the critical speed (also called the 85th percentile speed).
• A survey of the roadway and roadside conditions.

If the Agency agrees that a speed zone is justified, a recommendation is presented to the
Board of Supervisors. Should the Board approve the zone, signs are posted and enforcement can begin. Where local speed limits are to be enforced by radar or other electronic devices (such as laser meters), the studies must be no more than seven years old.
