EXECUTIVE SUMMARY In December of 1999, the City established speed zones on sections of various arterial and collector streets citywide (see attached Exhibit A). To be valid for radar. enforcement, as per California State Vehicle Code 22357, 22358,...and 22358.3, all speed limit studies must be reviewed and adjusted by ordinance every five (5) years from the date of the study, when development occurs.adjace'nt to a street, or major improvements are made to the roadway. 2. BACKGROUND Traffic speed studies, were conducted and speed zones established by Council in December, 1999, for various arterial, and collector streets .citywide as listed in Exhibit A. As a result of the .5 year time lapse since the existing study, a. request was presented to the traffic engineering division by the Police Department to conduct new studies to amend or re- establish the speed limits for the safety of the traveling public. Subsequent to the Police Department's request, studies were conducted on 33 street'segments citywide,, and the attached results indicate that in some cases, an adjustment to the existing speed limits was warranted. 3. ALTERNATIVES a. Ainend or re- establish. the speed limits to remain radar enforceable'. b. Do not amend speed limits and let the zones lapse, which will render them unenforceable by radar. 4. FINANCIAL IMPACTS Loss of revenue due to vehicular.speeding in an unenforceable speed zone. CONCLUSION Staff believes that the studies indicate an amendment to the. existing speed zones is required in some cases to meet the- present conditions in these sections of the City's street -3- rol 7. system. The'5 -year time-lapse has occurred, and re- establishment or adjustments of the speed zones is appropriate. OUTCOMES OR PERFORMANCE MEASUREMENTs THAT WILL IDENTIFY SUCCESS OR COMPLETION: Speed limits will be enforceable thus reducing the possible safety liability of not having .speed control for the traveling public in an urban setting. RECOMMENDATION Per-.California Vehicle Code 22357, 2235.8, and 22358.3, introduce an. ordinance approving the.recommended revisions, where indicated, or re= establishment of radar enforceable speed zones on various arterial and collector streets, as outlined in Exhibit A. 0 N 1 • -4- City of Petaluma n ideer n - and Traffic E g ' 'g c 'Survey Speed .Zone Summary , r • 1 ORDINANCE NO.
