FROM: BILL CROWE" CITY MANAGER
DATE: JUNE 16, 2004
RE: REQUEST TO INSTALL
AVENUE AT JACKSON
GRAVES AVENUE
TRAFFIC SIGNAUSTOP SIGN ON GRAVES
AVENUE AND INSTALL RED CURB ON
A letter was received from Ms. Lisa Chan, 2468 Jackson Avenue, for the installation of a
traffic signal and red curb at the intersection of Jackson Avenue and Graves Avenue.
Ms Chan has indicated that it is difficult to exit from Jackson Avenue on to Graves
Avenue because of the volume of traffic on Graves Avenue and a parked school bus
blocking visibility.
As stated in the attached Traffic Commission staff report dated May 19, 2004,
installation of a traffic signal or stop controls were not warranted pursuant to Caltrans
guidelines. However, based on field observations of where vehicles were parked and
the reported collision history, staff recommended that 30 feet of red curb be installed on
the north side of Graves Avenue east of Jackson Avenue to provide additional visibility
of approaching westbound traffic. In addition, it was recommended that 30 feet of red
curb be removed from the east side of Jackson Avenue north of Graves Avenue.
The Traffic Commission concurred with staffs recommendation and also recommended
that staff conduct a further investigation of the intersection for the installation of a traffic
signal and to ask the Sheriffs Department to place the speed trailer at this location.
RECOMMENDATION
It is recommended that the City Council approve the Traffic Commission's
recommendation to install red curb on the north side of Graves Avenue east of Jackson
Avenue and to remove 30 feet of red curb from the east side of Jackson Avenue north
of Graves Avenue.

exit from Jackson Avenue on to Graves Avenue because of the volume of traffic
on Graves Avenue and a vehicle blocking visibility.
CONDITIONS

each direction. A two-way left-turn lane separates opposing lanes of traffic.
Parking is allowed on both sides of Graves Avenue except where red curb exists.
Jackson Avenue is a 40-foot wide north-south roadway with one lane of traffic in

Field observations were made of the intersection during the mid-moming hours.
At that time, the vehicle M5. Chan described as being parked on Graves Avenue
east of Jackson Avenue was not present. However, other vehicles were parked
at that location which limited some of the visibility of southbound vehicles. The
traffic volumes on Graves Avenue did not appear to be heavy enough to cause a
significant delay to southbound vehicles on Jackson Avenue,
Traffic signals and stop signs are traffic control devices used. to determine right-
of-way at intersections. They are not speed control devices and, when not
properly installed, can increase speeds. The installation of signals and stop
signs are based on guidelines provided by Caltrans. These guidelines are based
on years of study and are the standard used by the City.
The 24-hour traffic volumes were compared to the Caltrans guidelines. Exhibits
C and D depict how the intersection of Graves Avenue/Jackson Avenue
measures up to the Caltrans guidelines. For both multi-way stop signs and traffic
signals, this intersection does not satisfy the guidelines. Therefore, the
installation of stop signs or signals is not recommended at this time.
RECOMMENDA710N
However, based on field observations and the reported collision history, it is
recommended that 30 feet of red curb be installed on the north side of Graves
Avenue east, of Jackson Avenue to provide additional visibility of westbound
traffic. In addition, 30 feet of red curb should be removed from the east side of
Jackson Avenue north of Graves Avenue. Exhibit A depicts these
recommendations.

Dear W. Wagner.
TEL:626-307-9218
#291U P.UUY/UUY
Per out telephone conversation on April 12, 2004, I have shared with you some concerns
regarding the Dttham wbool bus that is pinked in the coma of Jackson Avenue and
()raves 'Ilia school bus blocks the view of on coming traffic on Graves Avenue, wbkb
makes it very difficult to see and not to memion dangerous to turn left from Jackson
Avenue going east of Graves. As a Rosemead resident living on Jackson Avenue with
Macy others, we do not feel safe traveling in that direction. In fact, most reside= tae
&a:m and would avoid making turns in then area hecatue of the heavy and rapid traffic.
Years ago, it was not so bad. Recently, with new housing development between Qmvca
and Del Mar Avenue, traffic has been much more congested. As a result of this problem,
marry car accidents have been caused in that particular mr4L
To ensure safety and prosperity in our community, we are pnoposing that the city have A
uafftelight on (Graves and Jackson Avenue. Due to the growing population and the fast
and heavy flow of teaffiq it is to eity,s best intarst to consider having a traffic ligld
these, It is-also critical that the City of Rosemead paint the curb red on the comer of
Jackson Avenue and Graves, so that no vehicles are allowed to park them at anytime- .
This way, it would not block the view of a driver trying to make a left from Jackson
Avenue heading east of Graves.
It is imperative that the City of Rosemead resolves this matter as soon as possible to
avoid many more accidents in the area
Your quick response to this matter is deeply appreciated.
Sincerely,
Lisa Chan 2QbQj ~c.C' ~~~r 11 P. 002

ROSEMEAD TRAFFIC COMMISSION MEETING - I0
TUNE 3, 2004 41A~
A regular meeting of the Rosemead Traffic Commission was called to order by

Rosemead.

Present: Chairperson Knapp, Commissioner Quintanilla, Commissioner
Matsdorf & Commissioner Benjamin
Absent Commissioner Baffo
Ex-Officio: Assistant City Manager:
Traffic Engineering Deputy:
Traffic Liaison
CALL TO ORDER
Pledge of Allegiance: Commissioner Matsdorf
Invocation: Commissioner Benjamin
1. APPROVAL OF MINUTES
Donald J. Wagner
Joanne Itagaki
Sgt. Izell
The minutes for April 1, 2004, were deferred to the July meeting; due to a lack of
quorum.
II. ORAL COMMUNICATIONS FROM THE AUDIENCE - NONE
III. OLD BUSINESS - NONE
IV. NEW BUSINESS
A. REQUEST TO INSTALL TRAFFIC SIGNAL/STOP SIGN ON GRAVES ,
AVENUE AT JACKSON AVENUE AND INSTALL RED CURB ON GRAVES
AVENUE
Deputy Traffic Engineer Itagaki presented the staff report.
RECOMMENDATION:
Based on field observations and the reported collisiori history, it is recommended that
30 feet of red curb be installed on the north side of Graves Avenue east of Jackson
Avenue to provide additional visibility of westbound traffic. In addition, 30 feet of red
curb should be removed from the east side of Jackson Avenue north of Graves Avenue.
Speaking before the Commission was:
Lisa Chan
2468 Jackson Avenue
Rosemead, California 91770
Ms. Chan stated that with the growing population and a Durham Bus that parks at
Jackson and Graves makes it very difficult to see. In addition, to the accidents that have
occurred, she feels this recommendation is needed.
Speaking before the Commission was:
Michael Jerome
Director at Maryvale
Mr. Jerome presented the Commission with pictures and a letter. Mr. Jerome feels most
of the problem is coming from the west to the east and that one of their children nearly
got hit. There are also two school (Williams and Monterey Vista), where cars build up
speed and feels there is a need for a stop sign for safety reasons.
Deputy Traffic Engineer Itagaki stated she was looking at the collision history and there
was only 1 reported incident, but not all collisions are reported.
Assistant City Manager Wagner stated that traffic signals are very expensive and
therefore, further studies should be made.
Deputy Traffic Engineer Itagaki stated that when a stop sign is installed where it is not
warranted, people have a tendency to run it. Therefore, more data would need to be
collected in order to see if a signal is warranted at this location.
Speaking before the Commission was:
. Crystal Orozco
Student Q Rosemead High School
Ms. Orozco stated that perhaps the Commission should look in placing blinking lights
in the middle of the street, she feels this helps with slowing down traffic.
Commissioner Benjamin stated that there is a "law of unattended consequences", when
putting a light or a stop sign, it not only changes the traffic pattern on the street, but it
extends it and changes traffic patterns in all directions and on other streets. The
Commission always keeps this in mind when making a change to a street.
It was moved by Commissioner Matsdorf, seconded by Commissioner Benjamin, and
carried unanimously to approve the Traffic Engineer's recommendation and direct staff
to do some further studies for a traffic signal. In addition, to ask the Sheriffs
Department to place the speed trailer at this location.
V. STAFF REPORTS
Deputy Traffic Engineer Itagaki stated that at the last Council meeting all the items
were approved regarding traffic issues.
Sgt. Izell stated that in April the City of Rosemead had a DUI Checkpoint, and there
will be another one in the near future, and were very successful.
Sgt. Izell informed the Commission that pocket bikes are illegal on the road and off-
road, and can only be ridden on a closed-controlled track, i.e., Irwindale, and continue
to be an enforcement problem for the Sheriffs.
VI. COMMISSIONER REPORTS
Commissioner Benjamin stated that at Rosemead Boulevard and Mission the students
from the high-school seem to be jay-walking and ignoring the signals, causing a very
dangerous situation.
Deputy Traffic Engineer Itagaki stated that the reason there is a left turn arrow at this
location, is because when there is a break in traffic it seems to help, and possibly
enforcement could look into it.
VII. ADTOURNMENT_.
There being no further business to come before the Commission, the meeting was
adjourned at 7:32 p.m., with 23 people in the audience. The next meeting will be held
on July 8, 2004.
