SUBJECT: Discussion andTntroduction (First Reading) of an Ordinance to Establish Radar
Enforceable'Speed Limits on Certain Streets within the City of Petaluma.
IBC®MIVIENDATION
Introduce an ordinance establishing radar enforceable speed limits, on certain streets within the
City of Petaluma.
BACKGROUND
Engineering 'and traffic surveys must be conducted prior. to establishing speeds limits on an
existing street. Traffic 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 will not
change if there is no significant change to existing traffic conditions.
I)ISCIJSSLON
The Traffic Engineering pvision of the Public Works Department has conducted updated
studies to amend or re-establish the speed .limit on thirteen City street segments for the safety of
the traveling public. These.sections are in addition to the segments updated in December of
2009, with the exception. of Weaverly Drive. Subsequent to adoption of the December 2009
ordinance, Public Works staff discovered a typographical error on the Weaverly Drive survey.
Based on this, Weaverly Drive has been adjusted accordingly in this agenda bill to accurately
reflect the speed survey data. -
The California Vehicle Code (CVC) and California Manual on Uniform Traffic Control Devices
(MUTCD) require that an engineering aril traffic survey be performed to determine and establish
prevailing speeds. Agencies are required by the CVC and MUTCD to set posted limits at the
8S`" percentile speeds; obtained during the speed survey,, There are four street segments, shown in
bold letters on the table below, in which speed limits are. .required to be increased by 5 MPH.
The 85`h percentile speed for each of these four segments was 9-10 MPH above the current
posted limit. In these cases, the engineer of record ,has. the authority and discretion to
Agenda Review
Dept. Director City Attorney finance Director ~ City Mana
recommend dropping the new limit by 5 MPH for reasons such as higher than expected
collisions, road width, curvature, grade and other alignment conditions. The speed limit does not
change for the other nine segments, but the surveys are still required to revalidate existing posted
speed limits. Individual street segments for the speed surveys are available for review upon
request.
Recusal of the Mayor or any council members is not necessary because all street segments
proposed to be modified are not within 500 feet of any of the Mayor/council members' real
property.

F>(NANCLAL IMPACTS
Total Cost of Proposal or Project: Updating the speed survey is a responsibility of Public
Works Department's~Engineering Division, and as such, the work is anticipated and included in
the operating budget. Updating the surveys allows the Police Department patrol officers to issue
citations for speeding violations, which promotes increased safety on public streets.
Additionally, if the City did not update its speed surveys, a loss of revenue would occur, due to
the inability of the Police Department to issue citations for vehicular speeding in unenforceable
speed zones.
