Emerson Place and Hellman Avenue is approximately 1,275' (feet) in length.
Emerson Place: Within the City of Rosemead, Emerson Place runs east and west, and is considered
a major collector road with a speed limit of 30 MPH per the adopted 2013 City of Rosemead
Engineering and Traffic Survey (Speed Survey). Emerson Place is approximately 36' (feet) wide
with one lane of travel in each direction, and a dashed yellow center line dividing eastbound and
westbound traffic. Parking is permitted on the north and south side of Emerson Place where the
curbs are not marked red and outside of hours marked for street sweeping. This segment of
Emerson Place runs through light multiple family zoning, per the Rosemead General Plan.
Hellman Avenue: Within the City of Rosemead, Hellman Avenue runs east and west, and is
considered a major collector road with a posted speed limit of 30 MPH per the adopted 2013 City
of Rosemead Engineering and Traffic Survey (Speed Survey). Hellman Avenue is signal
controlled at the intersection with Jackson Avenue. Hellman Avenue is approximately 39.75' (feet)
wide with one lane of travel in each direction and a protected left turn pocket for traffic making a
left turn onto Jackson Avenue. Parking is available on the north and south side of the street except
during street sweeping and areas marked with red curb. This segment of Hellman Avenue travels
through light and medium multiple family zoning per the Rosemead General Plan.
Collision Investigation: A Collision History Analysis and investigation was conducted for the
subject location. Collision data was obtained from the computerized collision records system
maintained by the State of California called the Statewide Integrated Traffic Records Systems
(SWITRS). The collision analysis was conducted over approximately a 5 -year period between
January 2017 through December 2021 (available data at the time of traffic review) along the
segment of Jackson Avenue between Emerson Place and Hellman Avenue). There were 6 reported
collisions with no reported collisions in the years of 2021 or 2020. Out of the 6 collisions reported,
3 were reported as improper turning as the primary collision factor, 2 due to reported speeding,

damage only.
Average Daily Traffic (ADT): Average Daily Traffic (ADT) data was obtained from counts taken
on February 3rd, 2022, for Jackson Avenue between Emerson Place and Hellman Avenue. The
traffic count indicates that 1,909 vehicles per day travel on this section of Jackson Avenue.
Speed Survey: To assess the speed at which vehicles were traveling along Jackson Avenue, a
speed sample was taken over a 24-hour period on February 3rd, 2022. Based on the Speed Survey,
the 85th percentile speed of vehicles along Jackson Avenue was determined to be 33 mph. This
translates to mean that 85 percent of the vehicles sampled were traveling at 33 mph or below,
which is slightly above the speed limit of 25 mph. It is recommended to notify the Sheriff's
Department of speeding concerns and to request the Department conduct monitoring and targeted
enforcement of the area.
STAFF RECOMMENDATION
The Traffic Commission voted 4-0 to approve all staff recommended items with a modification to
include the installation of a speed limit pavement legend striping (Recommendation No. 4 below).

Traffic calming is the process of reducing vehicle speeds using both passive devices, such as signs and
striping, and physical devices such as changes in road elevation or path. As part of this study, traffic
speeds, collisions and traffic volumes were used to assess existing conditions along this segment. The
type, design and placement of traffic calming devices depend upon the road classification, desired traffic
speed and types of traffic issues along Jackson Avenue between Hellman Avenue and Emerson Place.
A single traffic calming device placed along a long stretch of road will be marginally effective at slowing
down speed at that isolated location. Implementation of a series of traffic calming devices that work
CITY OF ROSEMEAD

TRAFFIC REVIEW ON JACKSON AVENUE BETWEEN EMERSON PLACE AND HELLMAN AVENUE
together have been shown to reduce traffic speeds along the length of the corridor. There are various
traffic calming measures that can reduce the flow and speed of traffic on a street. The following is a list of
common traffic calming measures that can be installed to aid in slowing traffic.
The below traffic calming measures and strategies were reviewed for this roadway segment.
1) Traffic Education Campaign: This consists of flyers, neighborhood meetings, banners and other
notices to assist is making the public aware of the traffic conditions in a certain area.
2) Signage and Pavement Legends: Modifying the signage along the road or change the striping to
narrow travel lanes to effectively slows speeds by changing the travel environment. Signs alert the
Driver to their speed, such as larger speed limit signs or a speed feedback sign. Too many signs can
have an opposite effect on traffic. Therefore, usage of signs should be subject to careful consideration
and compliance with local and regional standards.
3) Larger Dimension Signs: Installation of larger dimensioned signage are recommended as treatments
to increase the motorist's awareness and other Driver conditions by highlighting various areas of the
roadway. All sign dimensions should comply with the dimensions specified in the California Manual of
Uniform Traffic Control Devices (CAMUTCD) Table 2B-1 Regulatory Sign and Plaque Sizes. The larger
sizes are shown in the multi -lane column as 36"x36" for stop signs and 30"x36" for speed limits.
Table 2B-1. Regulatory Sign and Plaque Sizes (Sheet 1 of 4)
4) Traffic Striping: Roadway striping can be implemented as an option that is a low-cost alternative to
Vertical/horizontal traffic calming measures. This includes a white stripe painted along both sides of
the travel way or a center stripe both give the driver a perception of a narrower road.
5) Targeted Police Enforcement: The police department should be notified of speeding concerns along
this segment and officers should conduct monitoring and targeted enforcement for this area.

RECOMMENDATIONS
After a thorough review of existing field and 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, it was determined that the segment along Jackson Avenue between Emerson
Place and Hellman Avenue would benefit from a combination of traffic calming measures and
improvements. Per the analysis of existing roadway conditions, the speed survey, and average daily traffic
count (ADT) it was determined that further oversized signage should be installed on Jackson Avenue to
alert drivers of the speed limit for both northbound and southbound travel as well as installation of a
center stripe to visually narrow the roadway and designate the travel lanes. Please refer to the Figure 4.
for the proposed recommendations for this study location.
The recommended items include:
1. INSTALL NEW OVERSIZED SPEED LIMIT SIGN: Install new oversized 25 MPH speed limit (112-1) sign
(30"X36") approximately 23 -feet north of the Emerson Place and Jackson Avenue intersection on
for northbound traffic as shown below in Figure 4. (Per CAMUTCD Section 28.13 and CAMUTCD
Table 2B-1).
2. INSTALL NEW DOUBLE YELLOW CENTER LINE (CAMUTCD 38.01) NO PASSING along Jackson
Avenue between Emerson Place and Hellman Avenue. This will serve to visually narrow the
roadway and designate he travel lanes, which is effective in reducing vehicle speeds. (Per

Rosemead Traffic Commission Meeting
Minutes of May 5, 2022
Page 1 of 9
Traffic Engineer Robbins explained that the resident requested the City to conduct a traffic review
along Jackson Avenue between Emerson Place and Hellman Avenue due to reported speeding
concerns.
Traffic Engineer Robbins explained as part of the traffic review, engineering staff looked at the
existing roadway conditions, a review of approximately 5 years of available collision data, Average
Daily Travel (ADT) counts, and a 24-hour Speed Survey.
On behalf of the City of Rosemead, Traffic Engineer Robbins provided a combination of traffic
calming measures and improvements along Jackson Avenue between Emerson Place and
Hellman Avenue.
Vice Chair Quintanilla opened the Public Comment period
Sherman Rourman, business owner of 8424 Garvey Avenue, questioned the validity of the data
collected for the traffic review stating the police does not take traffic accident reports anymore,
unless a personal injury is involved.
Vice Chair Quintanilla reiterated Mr. Rourman's comment to confirm if he was saying that there are
accidents not documented by the sheriffs.
Mr. Rourman confirmed that is correct. He explained that the sheriffs either arrive too late or do not
respond or take in traffic accident reports for damage or theft under $2,000. He commented that
the number of accidents indicated in the traffic review does not reflect the actual numbers, which is
significantly higher.
Vice Chair Quintanilla asked if Mr. Rourman has personally called the Rosemead Public Safety
Center or sheriffs station.
Mr. Rourman replied that he just knows from personal fact and experiences. He mentioned of
multiple accidents that have occurred in the area and the police do not show up.
Vice Chair Quintanilla thanked Mr. Rourman for his public comments.
The City received a Public Comment via email from Resident Stan Lam explaining he has
witnessed cars speeding and racing on the street. He also commented that both the tenants and
owners of the property should receive the courtesy notification letters.
The City received a Public Comment via email from Resident Howard Thio requesting a four hour
time limit for street parking from Monday to Friday between 8:00 AM to 5:00 PM along Jackson
Avenue due to heavy traffic.
The City received a Public Comment via email from Resident Julie Jacks expressing her concerns
for safety of residents on Jackson Avenue due to speeding and cars not stopping at the
intersection of Emerson and Jackson. She also mentioned an overgrown tree in front of the school
Rosemead Traffic Commission Meeting
Minutes of May 5, 2022
Page 2 of 9
on the southwest corner of Emerson and Jackson that is covering the stop sign that needs to be
removed or trimmed.
Vice Chair Quintanilla closed the Public Comment period.
Commissioner Escobar agreed with staff recommendations.
Commissioner Drange asked if the center double yellow lines will be installed on the whole street.
Traffic Engineer Robbins responded it will be from Emerson Place to Hellman Avenue.
Commissioner Drange asked if we could paint the speed limit on the road, which he explained
would be more useful than a speed limit sign as there is a lot of parked cars and trees along the
street.
Traffic Engineer Robbins responded a pavement legend is an option we can also include.
Commissioner Drange asked if we could add the pavement legend to the recommendations.
Director of Public Works Chung responded we can add the recommendation.
Vice Chair Quintanilla asked if we have similar issues with the parallel streets.
Traffic Engineer Robbins replied there have not been complaints received for the other streets and
that Jackson Avenue would be the first street to get the double yellow center lines.
Commissioner Drange commented that it would make more sense to install the double yellow
center lines all the way to Garvey Avenue, instead of ending it at Emerson Place.
Traffic Engineer Robbins replied that they would need to measure how wide the street is to ensure
there is nine and a half to ten feet minimum of travel lane.
Vice Chair Quintanilla opened the Public Comment period
The City received a Public Comment via Zoom from Resident Ken explaining that the previous
homeowners of their home mentioned of a speeding car that crashed into the living room. He
mentioned that he noticed cars have been driving fifty to sixty miles per hour on Jackson Avenue.
He stated that the cars are speeding in the morning and afternoon while school children are
present, as well as in the evenings. He expressed concerns for the safety of the children and the
homeowner's property. He agrees with the recommendations, however, does not feel it will prevent
speeding. Instead, he suggested to install speed bumps.
Vice Chair Quintanilla closed the Public Comment period.
Vice Chair Quintanilla asked staff to explain the policy on speed bumps.
Rosemead Trak Commission Meeting
Minutes of May 5, 2022
Page 3 of 9
Director of Public Works Chung responded that the City currently does not have a speed hump
policy, so there are no speed humps installed within the city. There has been discussion at the last
City Council meeting regarding the speed hump policy and it is currently in preliminary stages to
bring to the Traffic Commission meeting in June or July to discuss implementing speed humps in

B. PARKING REVIEW: GREEN CURB INSTALLATION REQUEST AT 8408 GARVEY
AVENUE
Traffic Engineer Robbins provided a brief description of the item and presented a PowerPoint
presentation of the studies that were conducted.
Traffic Engineer Robbins explained that the received a request from a business owner to install
green curb in front of the new Live Work development at 8408 Garvey Avenue which is located on
the southeast corner of Garvey Avenue and Delta Avenue.
Traffic Engineer Robbins explained as part of the traffic review, engineering staff completed a
parking review and analysis of existing conditions as well as conducted a parking study on the
south side of Garvey Avenue between Delta Avenue and Earle Avenue on one (1) weekday to
determine the existing parking conditions and patterns.
On behalf of the City of Rosemead, Traffic Engineer Robbins provided recommendations and
options for the City to determine on what type of parking and curb markings should be installed and
enforced for this location.
Commissioner Drange asked if the entrance on Delta Avenue for this property has designated
spaces for pickups and drop-offs.
Traffic Engineer Robbins replied she did not have access to the information.
Vice Chair Quintanilla opened the Public Comment period.
Sherman Rourman, business owner of 8424 Garvey Avenue, commented that the side street is not
designed for regular entry and inconvenient to enter the subterranean parking. They would need a
space for vehicles to quickly pull in for pick-ups and drop-offs, which is usually located in the front
of the building. There is already no parking available along the 8400 block of Garvey Avenue and
cars ignore the two-hour parking signs.
Vice Chair Quintanilla closed the Public Comment period.

Director of Public Works Chung responded to Commissioner Drange's question earlier regarding
parking spaces at the property. There are 43 at grade parking spots and 96 subterranean parking
spots.
Commissioner Drange asked if the City has its own parking enforcement or is it the sheriff.
Director of Public Works Chung replied the City has their own Code Enforcement division.
Commissioner Drange commented it does not seem like the two-hour parking is enforced on
Garvey Avenue and added that installing green curb would not do much if there is no enforcement.
Director of Public Works replied that Code Enforcement has been informed of the issue and to
monitor and patrol this area.
Commissioner Drange asked if any of the parked vehicles were ticketed when they did the parking
survey.
Director of Public Works Chung replied he does not have that information since it was the traffic
team who conducted the parking survey and not Code Enforcement.
Commissioner Nguyen asked if the medical office requesting the green curb has a location to park.
Traffic Engineer Robbins replied when developments come in, they have to park to code onsite.
Planning division informed that this location needed 43 at grade parking spaces and 96
subterranean parking spaces. It is assumed that the subterranean parking is for the residents.
Director of Public Works Chung further explained that the 43 at grade parking spaces and 96
subterranean parking spaces is for the entire development. There is no parking in the front, only
parking in the back.
Traffic Engineer Robbins explained the request for green curb was primarily for dropping off and
picking up patients at the adult health care facility.
Vice Chair Quintanilla commented that the green curb could also serve as a handicap parking
zone.
Traffic Engineer Robbins mentioned vehicles parked in the space would not be cited as long as
they have a handicap placard. It was also not informed how long the visits would be, whether it
would be a quick office visit or all day.
Director of Public Works Chung commented the developers were requested to attend the meeting,
but there was no response received.
Commissioner Drange commented he would not make the entire 100' of curb just green. He asked
how many parking spaces is the proposed 100' of green curb.

Director of Public Works Chung replied approximately five parking spaces
Commissioner Drange suggested making a few spaces green and the remaining space as two-
hour parking. He also asked whether the business is looking for space to receive deliveries, which
would be yellow curb.
Director of Public Works Chung replied the request was for twenty minute green curb.
Commissioner Escobar asked about whether there would be inconsistencies with the parking
enforcement and if individuals would be able to call parking enforcement to notify of vehicles
parked longer than the permitted time allowed.
Director of Public Works Chung replied there should not be inconsistencies and that individuals
could report those vehicles.
Commissioner Escobar mentioned that there is existing green curb in front of 8424 Garvey Avenue
and asked whether it is currently being enforced.
Director of Public Works Chung replied that the green curb was not installed by the City.
Commissioner Nguyen asked if there is any benefit to having a yellow loading only or passenger
loading only instead of the green curb.
Traffic Engineer Robbins replied the yellow is for freight and passenger loading activities, typically
limited to three minutes.
Commissioner Nguyen asked about the 30 minute limit indicated on the yellow loading only sign
used in the presentation.
Traffic Engineer Robbins replied the signs used in the presentation were sample signs from
California Manual on Uniform Traffic Control Devices and that the signs would conform to
Rosemead's municipal code. She also explained that green curb allows vehicles to park, whereas
the yellow loading only is strictly for loading and unloading.
Commissioner Nguyen suggested to install one yellow and one green space, and the rest to be
two-hour parking.
Director of Public Works Chung replied the request was for green curb and it is assumed the green
curb would be sufficient for their operational needs.
Commissioner Drange asked if there is a time limit on the two-hour parking spaces.
Traffic Engineer Robbins replied it is from 7:00 a.m. to 6:00 p.m., except Friday.
Vice Chair Quintanilla asked if we could make sure to enforce the green curb once installed.
