SUBJECT: TRAFFIC CALMING MEASURES FOR IVAR AVENUE NORTH (BETWEEN
GRAND AVENUE AND MISSION ROAD) AND IVAR AVENUE SOUTH
(BETWEEN VALLEY BOULEVARD AND MARSHALL STREET)
SUMMARY
In March 2011, Traffic Commission asked staff to evaluate traffic conditions along Ivar
Avenue (between Valley Boulevard and Marshall Street) in response to resident concerns
regarding excessive speeding. As a result, several actions have been taken to help
encourage safe driving in this neighborhood, including installing new speed and warning
signs, mobile speed radar trailers and a Sheriffs Department 'decoy' car. Additionally, on
May 28, 2011, a public meeting was held at the Rosemead Community Center to gain
additional information regarding the continued speeding issues along Ivar Avenue and
present effective ways to reduce speeding along this residential corridor.
At the recent August 4, 2011 Traffic Commission meeting, another request was made to
investigate dangerous conditions along Ivar Avenue between Mission Road and Grand
Avenue. At the August meeting, the Traffic Commission requested that staff review
findings for both segments of Ivar Avenue and report back with recommendations for street
striping /traffic calming and report back to the Commission. Staff developed a set of safety
measures to address these traffic conditions.
Staff Recommendation
It is recommended that the Traffic Commission:
1. Provide input on proposed traffic safety measures proposed by staff along
both segments of Ivar Avenue; and
2. Authorize the Traffic Commission to recommend to the City Council that traffic
safety measures be made along both north and south segments of Ivar
Avenue, including the installation of additional street striping, rumble strips,
and speed feedback signs.
ANALYSIS
At the March 3, 2011 Traffic Commission meeting, several residents along Ivar Avenue

between Valley Boulevard and Marshall Street expressed the need to seek solutions to
speeding along this residential corridor. As a result, several actions have been taken to
help encourage safe driving in this neighborhood, including:
• The installation of new speed limit signs and street markings;
• The installation of speed warning signs ( "Watch Your Speed, We Do" with an icon of
a motorcycle traffic enforcement officer and speed radar gun); and
• The use of a Sheriff's Department "decoy" car and mobile speed radar trailer.
However, indications were that speeding violations have continued to persist along this
corridor. The Traffic Commission asked that staff investigate possible solutions to the
speeding problems along Ivar Avenue and report back with recommendations.
On May 28, 2011, the City held a community meeting to obtain additional input to address
unsafe traffic conditions along Ivar Avenue. At this meeting, several possible solutions
were introduced that would effectively slow down traffic. The attendees were presented
with an introduction to the methods of addressing excessive speed including the three 'E's
(Education, Enforcement, and Engineering). The three 'E's include the use of radar speed
feedback and other traffic calming signs, bicycle lane striping and rumble strips.
At the recent August 4, 2011 Traffic Commission meeting, another request was made to
investigate dangerous conditions along Ivar Avenue between Mission Road and Grand
Avenue. The Traffic Commission requested that staff review findings for both segments of
Ivar Avenue and report back with recommendations for consideration.
In August 2011, staff initiated a study to research previous accidents along the Ivar Avenue
corridor using the State's Statewide Integrated Traffic Records System or SWITRS
database as a way to identify incidences of traffic related collisions. The records show that
during the last three years, Ivar Avenue between Valley Boulevard and Marshall Street
reported seven collisions and Ivar Avenue between Grand Avenue and Mission Road
reported one traffic collision. It was concluded that Ivar Avenue between Valley Boulevard
and Marshall Street had an unusually high incident of reported traffic collisions. However,
the data did not support the same high incidents along Ivar Avenue between Grand Avenue
and Mission Road where only one traffic collision occurred during the same three -year
period.
Based on continued and ongoing research of the traffic situation on Ivar. Avenue (for the
two north and south roadway segments) and inputs from the recent community meeting,
staff recommends that the Traffic Commission consider the following traffic measures be
installed at both Ivar Avenue locations (Grand Avenue to Mission Road and Valley
Boulevard to Marshall Street):
• Installation of radar speed feedback signs at mid -block locations,
• Installation of "Traffic Calming Zone" signs at the both ends of the roadway

segments,
• Striping of new edge lanes on along both sides of the roadway,
• Striping and /or restdping of center lane markers, and
• Installation of rumble strips at appropriate locations of the roadways.
In addition, the Sheriff's Department will continue to enforce speed laws and deploy 'decoy'
vehicles for both Ivar Avenue roadway segments.
Staff anticipates a budget not -to- exceed $30,000 to implement for this Ivar Avenue Traffic
Safety Improvement Project. This includes the purchase and installation of all above
recommended improvements. Staff will continue to monitor the conditions of the
recommended traffic safety measures and report to the Traffic Commission of their
effectiveness to reduce speeding along Ivar Avenue.
