EXECUTIVE SUMMARY: Per California State Vehicle Code 22357, 22358, and 22358.3, speed studies must be conducted prior to establishing and posting radar enforceable speed limits on roadways where development adjacent to the street, major road improvement, or changes in traffic conditions have occurred, and radar enforcement is prudent. 2. BACKGROUND: Traffic speed studies are required prior to establishing speeds limits on an existing street. Conditions may change as a result of street improvements, development, or changes in traffic and/or pedestrian use, which necessitate establishing radar enforceable speed limits for the safety of the traveling public and pedestrians. Existing speed zones not changed remain unchanged. The various speed zones Citywide are illustrated in the attached Speed Zone Map. Listed in the following table are the speed zone changes proposed. In some cases the speed limit does not change, however the limits of the zone are changed. As well, there are several clerical corrections from previous Speed Ordinances. The following table summarizes the various speed zones being changed. PROPOSED, CURRENT STREET FROM TO SPEED LIMIT SPEED LIMIT MPH/(Km/Hr.) MPH/(Km/Hr.)

Do not establish radar enforceable speed limits, which will render them unenforceable by the Police Department. 4. FINANCIAL IMPACTS: Loss of revenue, due to inability to issue citations for vehicular speeding in an unenforceable speed zone through the City. 3 5. CONCLUSION: Staff believes that the studies indicate the establishment of speed zones is required to meet the existing conditions in these sections of the City's street system and provide for the safety of the traveling public. 6. 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 in an urban setting. RECOMMENDATION: Approve the ordinance, establishing radar enforceable speed zones on various City of Petaluma streets, as outlined in Exhibit B.
