A field investigation was conducted on June 12, 2024, which included site observations at the
intersection of Marshall Street and Chariette Avenue. It was observed that the stop sign and the "STOP"
pavement marking, located on the south-west corner of the intersection, were faded and in poor
conditions. It was noted that the fire hydrant located along the south side of Marshall Street, east of
Chariette Avenue did not have sufficient red curb marking. The available line of sight, for vehicles
turning into Marshall Street, from Chariette Avenue was found to be insufficient.

LINE OF SIGHT REVIEW
A Line -of -Sight analysis consists of reviewing the existing conditions a driver encounters when
approaching an intersection to turn onto the other street and determining if there is limited view for the
driver turning. The driver of a vehicle approaching or departing from an intersection or driveway should
have an unobstructed view of the intersection, including any traffic control devices, and sufficient
lengths along the intersecting highway to permit the driver to anticipate and avoid potential
obstructions. Per California Highway Design Manual, any object within the sight triangle that would
obstruct the driver's view of an approaching vehicle should be removed or modified. Obstructions
within sight triangles could be buildings, vehicles, hedges, trees, bushes, tall crops, walls, fences, or
parked cars. A parked vehicle extends approximately 7 -feet from the curb, for this reason, it's necessary
to consider the width of a vehicle when determining the amount of red curb needed to obtain a clear
line of sight. At intersections in urban areas where street parking is allowed, the common practice by
motorists after stopping at the curb and watching and yielding for any potential pedestrians crossing on
the sidewalk, is to pull a sufficient distance forward to the edge of the parking lane to have a better view
of oncoming traffic. Figure 6 presents an example of a clear sight triangle at an intersection.

ALL -WAY STOP CONTROL CRITERIA FOR DETERMINING IF STOP CONTROL IS WARRANTED
Traffic control devices work in concert with the basic "rules of the road" contained in traffic laws and
ordinances. The California Manual of Uniform Traffic Devices (CAMUTCD) describes applications,
warrants, and placement of STOP signs (111-1). The STOP sign is a regulatory device that is used when
traffic is required to stop. STOP signs are used to assign right-of-way at an intersection. Multi -way control
is used where the volume of traffic on the intersecting roads is approximately equal. Stop signs are not
used as a speed control device. Since a STOP sign causes inconvenience to motorists, it should be used
only where warranted. There are several factors that an intersection needs to meet forthe consideration
of all -way stop control; criteria include minimum volumes on each of the street approaches, collision
investigation, speed of traffic, number of pedestrians and potential sight obstructions.
Prepared By: Transtech Engineers, Inc. I Page 7 of 17
TRAFFIC REVIEW OF THE INTERSECTION OF MARSHALL STREET AND CHARIETTE AVENUE
All -Way Stop Installation
The following briefly outlines the Criteria for the installation of All -Way stop warrants.
The placement of All -Way stop control is warranted when' minimum volume thresholds are exceeded:
A. Traffic control signals are justified.
B. A crash problem exists as indicated by 5 or more collisions in a 12 -month Period.
C. Minimum Volumes are met if:
1. Volume entering intersection from the major approach (total of both approaches) averages
300 vehicles Per hour for any 8 hours of an average day. And
2. The combined vehicle, pedestrian and bicycle volumes entering the intersection from the
minor street approaches averages at least 200 units per hour for the same 8 hours.
3. If the 85th percentile approach speed of the major street exceeds 40 mph the minimum
volumes are 70 percent of the above values.
Peak hours used in Table 2 are from ADT counts taken on each approach on Marshall Street and Chariette
Avenue to determine if the intersection met volume warrants for all -way stop installation.
The following Table 4 summarizes traffic during the highest 8 peak hours of the day on both streets.

and do not meet the minimum vehicular volumes stated in the CAM UTCD warrants. Additionaly, the
intersection does not meet the minimum collision volumes. For or these reason, the intersection of
Marshall Street and Chariette Avenue does not qualify for the installation an All -way Stop control at the
moment.
After a thorough review of existing traffic conditions and per the California Manual on Uniform Traffic
Control Devices (CAMUTCD), California Vehicle Code (CVC), based on the traffic review and engineering
judgement, the intersection of Marshall Street and Chariette Avenue does not qualify for the installation
of an All -Way Stop control. The intersection did not meet the minimum vehicular volumes, as well as did
not meet the required number of collisions in a 12 -month period. However, it was determined that the
intersection of Marshall Street and Chariette Avenue qualifies for the following improvements:
Recommendations:
1. REMOVE AND REPLACE STOP SIGN (117 —1): Remove and replace faded stop sign with new Stop Sign
(Rl — 1) located on the east side of Chariette Avenue, at the intersection with Marshall Street, for
northbound traffic approaching the intersection.
2. INSTALL "CROSS TRAFFIC DOES NOT STOP" PLAQUE (W4 —4P): Install "Cross Traffic Does Not Stop"
plaque (W4 — 4P) beneath existing stop sign that is located on the east side of Chariette Avenue, at
the intersection with Marshall Street, for northbound traffic approaching the intersection.
3. INSTALL RED REFLECTIVE STRIP: Install red reflective strip on the existing stop signpost, located on
the east side of Chariette Avenue, at the intersection with Marshall Street for northbound traffic.
4. REFRESH "STOP" AND STOP BAR PAVEMENT MARKINGS: Refresh Stop Bar and "STOP" pavement
legend markings located along Chariette Avenue, at the intersection with Marshall Avenue, for
northbound traffic.
S. INSTALL RED CURB AT SOUTHWEST CORNER OF THE INTERSECTION: Install 20 -feet of red curb along
the south side of Marshall Street, west of Chariette Avenue. The addition of this red curb will improve
the line of sight at the intersection for vehicles approaching Marshall Street from Chariette Avenue.
6. INSTALL RED CURB AT THE SOUTHEAST CORNER OF THE INTERSECTION: Install an additional 15 -feet
of red curb east of the fire hydrant that is located along the south side of Marshall Street, west of
Chariette Avenue. (CVC Section 22514).

3. NEW BUSINESS
A. ALL WAY STOP REQUEST AT OLNEY STREET AND ELLIS LANE
Chair Drange opened the public comment period
The City received a public comment from Belinda Rosales stating she is in favor of installing a stop sign at
Olney Street and Ellis Lane, mentioning vehicles are speeding on Olney Street. Ms. Rosales asked if speed
bumps could be another option as there are no sidewalks and cars do not slow down. She also mentioned
an incident involving a police vehicle pursuit and how these drivers tend to end up driving through Olney
Street. It was also mentioned that the residents residing on Olney Street have been requesting sidewalks,
closure of the Olney Street freeway on-ramp, and speed bumps.
Chair Orange closed the public comment period.
Associate Engineer Richter provided a brief description of the item and presented a PowerPoint
presentation of the studies that were conducted.
Rosemead Traffic Commission Meeting
Minutes of July 11, 2024
Page 1 of 8
Associate Engineer Richter explained that the City received a resident request to review the intersection for
Olney Street at Ellis Lane to determine if the intersection meets the requirements for an all -way stop. The
request reported vehicles will often travel on Olney Street at a high rate of speed and is concerned for
vehicles and pedestrians traveling through this area. The resident requested that an all -way stop be
installed at the intersection. In response to this request and on behalf of the City, engineering staff
completed a traffic review to determine if an all -way stop was warranted to be installed at the intersection of
Olney Street and Ellis Lane, and recommended appropriate measures.
After a thorough review of existing field and traffic conditions and per the guidelines in the California Manual
on Uniform Traffic Control Devices (CAMUTCD), California Vehicle Code (CVC), and based on engineering
judgement, it was determined that the intersection of Olney Street at Ellis Lane does not meet the
requirements for the installation of an all -way stop. However, it was determined that this area along Olney
Street at Ellis Lane would benefit from the installation of other traffic calming measures.
Chair Drange asked if there was a reason no other traffic calming measures were considered such as
roadway side striping.
Associate Engineer Richter replied there are a few items to consider with side striping, including if there is
enough space for the parked cars as well as the travel lanes. At this time, the side striping would not work
due to the street not being wide enough.
Vice Chair Lang commented that he occasionally walks along Olney Street and although there is no
sidewalk, he stated he feels relatively safe. He reiterated the resident's public comment mentioning that the
concerns appear to be coming from speeding vehicles traveling eastbound trying to enter the freeway on-
ramp. He asked if there was any data that showed this and what time of the day the studies were
conducted.
Associate Engineer Richter replied the data was collected over a 24 hour period for the average daily traffic
as well as the speed.
Traffic Engineer Robbins added that within the 24 hour speed survey, the summary indicates that the 85t"
percentile is at 30, meaning 85% of vehicles are traveling 30 miles per hour or less. There were 14%
between 30 to 39, which is higher than the posted 25 miles per hour speed limit.
Chair Drange asked the commissioners if they would like to table this item until after the next item is
discussed regarding the All Way Stop Request at Olney Street and Marybeth Avenue.
Commissioner Chang made a motion, seconded by Commissioner Nguyen, to table item 3A until
after discussion of item 3B on the agenda. Vote resulted in:
Yes: Chang, Nguyen, Lang, Drange
No: None
Abstain: None
Absent: Hermosillo

Page 2 of 8
Associate Engineer Richter explained that the City received a resident request to review the intersection for
Olney Street and Marybeth Avenue. to determine if the intersection meets the requirements for an all -way
stop. The request reported vehicles will often travel on Olney Street at a high rate of speed and is
concerned for vehicles and pedestrians traveling through this area. The resident requested that an all -way
stop be installed at the intersection. In response to this request and on behalf of the City, engineering staff
completed a traffic review to determine if an all -way stop was warranted to be installed at the intersection of
Olney Street and Marybeth Avenue, and recommended appropriate measures.
After a thorough review of existing field and traffic conditions and per the guidelines in the California Manual
on Uniform Traffic Control Devices (CAMUTCD), California Vehicle Code (CVC), and based on engineering
judgement, it was determined that the intersection of Olney Street at Ellis Lane does not meet the
requirements for the installation of an all -way stop. However, it was determined that this area along Olney
Street at Ellis Lane would benefit from the installation of other traffic calming measures.
Commissioner Chang asked if striping down the center line could be considered as an alternative option to
side striping.
Associate Engineer Richter replied that either a dashed or a double yellow could be considered.
Traffic Engineer Robbins added that for an all -way stop, there needs to be minimum threshold volumes for
each direction over a period of eight hours, and both these intersection locations do not have enough
volume to meet the warrant.
Vice Chair Lang asked why there is an all -way stop at the intersection of Olney Street and Vane Avenue.
Traffic Engineer Robbins replied it was likely grandfathered, as they did not place it, and as consultants,
standards and guidelines need to be followed.
Chair Orange asked if the striping would go just to the stop sign or from east and west end of the street
segment.
Commissioner Chang made a motion, seconded by Vice Chair Lang, to approve staff
recommendations for both item 3A and 36, with addition of installing a double yellow striping from
Temple City Boulevard to Rio Hondo Avenue. Vote resulted in:
Yes: Chang, Nguyen, Lang, Orange
No: None
Abstain: None
Absent: Hermosillo
C. ALL WAY STOP REQUEST AT JACKSON AVENUE AND GARVALIA AVENUE
Associate Engineer Richter provided a brief description of the item and presented a PowerPoint
presentation of the studies that were conducted.
Associate Engineer Richter explained that the City received a resident request to evaluate the intersection
of Jackson Avenue and Garvalia Avenue and determine if the intersection qualifies for the installation of an
all -way stop. The resident expressed concern for vehicles speeding through the area along Jackson Avenue
and has requested that an all -way stop or other traffic calming measures be installed at this location. In
response to this request and on behalf of the City, engineering staff completed a traffic review to determine

if an all -way stop was warranted to be installed at the intersection of Jackson Avenue and Garvalia Avenue,
and recommended appropriate measures.
After a thorough review of existing field and traffic conditions and per the guidelines in the California Manual
on Uniform Traffic Control Devices (CAMUTCD), California Vehicle Code (CVC), and based on engineering
judgement, it was determined that the intersection of Jackson Avenue and Garvalia Avenue does not meet
the requirements for the installation of an all -way stop. However, it was determined that this area along
Jackson Avenue and Garvalia Avenue would benefit from the installation of other traffic calming measures.
Chair Drange opened the public comment period.
The City received a public comment via Zoom from Ping Lau expressing safety concerns stating they have
lived along Jackson Avenue for over 15 years and have witnessed vehicles speeding up to 40 miles per
hour from Fern Avenue all the way to south of Graves Avenue. He mentioned in 2022, his dog ran out of
their gate and got hit by a driver. He also added that the intersection of Jackson Avenue and Garvalia
Avenue is a two-way stop, however, many drivers are unaware that Jackson Avenue does not have a stop
sign and will sometimes drive forward or make an unsafe tum.
Chair Drange closed the public comment period
Vice Chair Lang asked when the pedestrian study was performed and if it was during or after the school
year.
Associate Engineer Richter replied the study was performed at the end of the school year.
Commissioner Chang reiterated the residents' concerns regarding the intersection of Jackson Avenue and
Garvalia Avenue being a two-way stop, and drivers not knowing that. The proposed recommendations
should address help address that issue.
Vice Chair Lang asked for clarification on the recommendation to install red reflective strip on the stop
signpost.
Associate Engineer Richter replied it is a reflective tape that is placed on the stop signpost to allow more
visibility for approaching vehicles.
Vice Chair Lang made a motion, seconded by Commissioner Nguyen, to approve staff
recommendations. Vote resulted in:
Yes: Chang, Nguyen, Lang, Drange
No: None
Abstain: None

all -way stop. The resident expressed concern for vehicles speeding through the area along Marshall Street
and has requested that an all -way stop or other traffic calming measures be installed at this location. In
response to this request and on behalf of the City, engineering staff completed a traffic review to determine
if an all -way stop was warranted to be installed at the intersection of Marshall Street and Chariette Avenue,
and recommended appropriate measures.
After a thorough review of existing field and traffic conditions and per the guidelines in the California Manual
on Uniform Traffic Control Devices (CAMUTCD), California Vehicle Code (CVC), and based on engineering
judgement, it was determined that the intersection of Marshall Street and Chariette Avenue does not meet
the requirements for the installation of an all -way stop. However, it was determined that this area along
Marshall Street and Chariette Avenue would benefit from the installation of other traffic calming measures.
Chair Drange opened the public comment period
The City received a public comment from Betty Rodriguez stating she would prefer not to have a stop sign
placed at the intersection as it would be placed right in front of her house, however, understands the need
for it due to speeding vehicles between Walnut Grove Avenue and San Gabriel Boulevard. She commented
that there are more car accidents at Delta Avenue and Marshall Street and suggested a stop sign be placed
at that intersection.
The City received a public comment via email from Jenny Zhang expressing her safety concerns and
approval of speed limit and stop sign at the intersection.
The City received a public comment via email from Alfred & Carmen Fong supporting the installation of stop
signs at the intersection.
The City received a public comment via email from Lisa Ng supporting the installation of the all -way stop
signs at the intersection.
The City received a public comment via email from Mary Perez & Olga Perez supporting the installation of
the all -way stop signs at the intersection.
Chair Drange closed the public comment period.
Vice Chair Lang asked to confirm that the intersection will not have additional stop signs installed, and that
the proposed recommendations are to only refresh the existing sign and add red curb.
Associate Engineer Richter replied that is correct.
Chair Drange asked why the speed limit at this location 35 miles per hour and not 25 miles per hour.
Associate Engineer Richter replied the city conducts a citywide speed survey every ten years to review
vehicle speeds traveling along a segment and look at the 85 percentile and it recently conducted in 2023.
The speed limit on this segment was already 35 miles per hour before the speed survey was completed and
there were no recommendations to change or adjust because that is how fast the vehicles were traveling.
Traffic Engineer Robbins added that Marshall Street has different speed limits, with some segments being
30 and this segment at 35. In the speed survey, the 85 percentile for this segment was at 36 so the speed
limit was set at 35.

Chair Drange asked if at the time of the speed survey, would the question to lowering the speed limit been
possible.
Traffic Engineer Robbins replied there are certain items to look at in order to reduce the speed limit and one
being the number of collisions, accident rate, and land use around that segment. At the time it was
determined that 35 miles per hour was appropriate. In order to change the speed limit, another speed
sample on the segment would need to be conducted to see if the data justifies changing the speed limit. An
amendment to the speed survey would also be needed, which would then have to be adopted by City
Council.
Vice Chair Lang commented that all four traffic items discussed reported zero collisions within the last three
years, so it appears that as a city we are not reporting accidents or another issue.
Chair Drange asked for this specific report, was just this particular intersection looked at for the collision
survey or also the street segments a few blocks away.
Traffic Engineer Robbins replied it was just at this particular intersection looked at for the collision survey. It
was also mentioned that in a lot of cities, the police department and sheriffs typically do not report collisions
if it is only property damage. For City of Rosemead, data is collected from Statewide Integrated Traffic
Records System (SWITRS).
Vice Chair Lang commented that if a speed survey were redone, the data likely would not change since
there are no new traffic calming measures in place. For the next speed survey, if the traffic calming
measures are effective on Marshall Street, we could propose changing the speed limit.
Commissioner Nguyen commented that it is alarming that the data shows 20% of the traffic going above 35
miles per hour and 1% of traffic is going above 45 miles per hour. With around 5,000 vehicles, that is
approximately 50 vehicles driving at those speeds.
Commissioner Chang commented that Marshall Street appears to be categorized as a major collector road
as opposed to the other streets looked at which are local roads. He asked if Marshall Streets serves some
other purpose such as for evacuation and if that needs to be considered.
Traffic Engineer Robbins replied Marshall Street was classified as a major collector by Caltrans, and
mentioned that the city receives certain funds for collectors and above, while local roads do not receive road
funds from Caltrans or Metro. There is a process required to change that road designation.
Commissioner Nguyen commented that the city should revisit the discussion on speed hump policy as the
traffic calming measures may not be sufficient in certain areas.
Director of Public Works Wang replied that the commission and city council did recommend for the city to
move forward with developing a speed hump policy and staff is currently working on it to bring to City
Council meeting on July 23rd.
Commissioner Chang commented that a temporary measure to help slow down traffic could be using plastic
bollards to narrow the road.
Chair Drange recalled in a few past traffic items, as part of the traffic calming measures, side striping and
double yellow center line was recommended.

Vice Chair Lang asked how it looks east of Walnut Grove Avenue along this segment
Chair Drange replied traffic is slower due to Janson Elementary being over there, as well as a stop sign at
Bartlett Avenue and another stop sign at Muscatel Avenue,
Commissioner Nguyen made a motion, seconded by Vice Chair Lang, to approve staff
recommendations, and to include white side striping and double yellow center lines on Marshall
Street from Walnut Grove Avenue to the westerly city limits. Vote resulted in:
Yes: Chang, Nguyen, Lang, Drange
No: None
Abstain: None
Absent: Hermosillo
4. MATTERS FROM STAFF None
5. COMMISSIONER REPORTS
Commissioner Nguyen commented that she had recently attended a Los Angeles Board of Supervisors
Leadership Conference and one of the key topics included discussions on public transportation within the
City of Los Angeles and Los Angeles County in preparation of FIFA 2026 and the Olympic Games in 2028.
She wanted to just put a reminder on that to keep in consideration as we may get a lot of visitors in the
Rosemead area.
Vice Chair Lang recalled an item that was brought up in the previous meeting regarding Rosemead
Boulevard and Mission Drive, by the In -N -Out that has been causing a lot of traffic at the intersection. Part of
the discussion also included potentially looking into Mission Drive and the lighting in the area. He asked
what the SLA or the response time.
Director of Public Works Wang replied she did not have a response time, however, the item was added to
the qua for traffic review.
Chair Drange commented that there has been an increase of motorized vehicles such as mopeds and
electric scooters riding on the sidewalk, especially along Valley Boulevard and Garvey Avenue. The city
does allow for bicycles on sidewalk, however, questioned if mopeds or electric scooters would be included.
He asked if it could be looked into to make it safer for pedestrians.
Commissioner Chang agreed with Chair Drange's comment and mentioned that nearby jurisdictions are
looking into that issue to address these alternative modes of transportation.
Director of Public Works Wang replied it will be looked into.
6. ADJOURNMENT
