RECOMMENDATION Itis recommended that-.the CityCouncil introducean ordinarice'to establish radar enforceable speed limits on,certain'streets withinthe City of Petaluma. BACKGROUND The City must conduct engineering,andctraffic surveys prior to establishing speed limits on an existing street. Over time, traffic conditions change as a result of street' improvements, development, or changes•in'traffic and/or"pedestrian use which necessitate reviewing, resetting or establishing radar enforceable:;speed limits for the safety of the traveling public and pedestrians. Existing speed zones will not change if there is no significant change to existing . traffic conditions: - • DISCUSSION The.California Vehicle Code(CMC) and°California Manual on Uniform Traffic Control Devices (MUTCD) require that an engineering-and traffic survey be performed to determine and establish prevailing speeds on street segments 40' in width or greater and requires agencies to set posted limits atsthe85`h percentile of speeds obtained during the speed survey. (i.e. 15%of surveyed ' vehicles•went faster and 859'0 went slower) The Traffic Engineering Division of the Public Works and Utilities Department and the Traffic Enforcement,and Safety Division of the Police Department coordinate on a regular basis to make certain speed surveys exist and,are updated as necessary in`accordance:with State law and local regulations:The Traffic Engineering Division has conducted a'study to establish posted speed limits on Redwood Way between North McDowell Boulevard and Old:Redwood Highway, and on 2"d Street;between D';Street,and G Street. Both-street:segments'exceed 40 feet in width, measured curb to curb and therefore require.a speed surveytoestablish posted speed limits.

The posted speeds on both sections of Petaluma Boulevard South have been re-established at 35 MPH, based:on the results of the,speed survey, This-new posted:limit is.10 MPH less than the previous speed limit of 45 MPH..
