SUBJECT: APPROVAL OF TRAFFIC IMPROVEMENTS ON RAMONA
BOULEVARD BETWEEN BURTON AVENUE TO THE I-10 EB OFF
RAMPS/ROSEMEAD BOULEVARD
SUMMARY
At the November 3, 2022, Traffic Commission Meeting, staff presented recommendations and
options for traffic improvements on Ramona Boulevard from Burton Avenue to Rosemead
Boulevard. After discussion and presentation of the item, the Traffic Commission approved the
staff recommendations for the area as shown on the "Installation Exhibit' in Attachment C. Public
Works Field Services staff will complete all the recommended items. If necessary, additional
materials and supplies may be purchased at a minimal expense to complete the recommended work

BACKGROUND
The City of Rosemead received a resident request to evaluate the installation of speed humps along
the segment of Ramona Boulevard from Burton Avenue to Rosemead Boulevard. In response to
this request and on behalf of the City, engineering staff completed a traffic review and
recommended appropriate measures on Ramona Boulevard.
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 Ramona
Boulevard between Burton Avenue and Rosemead Boulevard would benefit from a combination
of Traffic Calming Measures. At this time, the City of Rosemead does not have a Speed Hump
Policy in place. Speed humps are usually only installed on roadways that meet certain criteria such
as being classified as a local street with minimum and maximum vehicles per day as well as posted

speed limits of 25 mph or less. Using this criteria Ramona Boulevard would not be eligible for
installation of speed humps.
At the November 3, 2022, Traffic Commission Meeting, staff provided a presentation regarding
existing field and traffic conditions along the segment of Ramona Boulevard from Burton Avenue
to Rosemead Boulevard. The traffic review included an analysis of the existing roadway
conditions, a review of approximately 3 years of available collision data, an average daily traffic
count (ADT), a 24-hour speed survey as well as an examination of existing field conditions.
Ramona Boulevard is an East/West Road classified by Caltrans as a major collector roadway.
Ramona Boulevard is approximately 28 -feet wide east of Ivar Avenue and approximately 32 -feet
wide west of Ivar Avenue, with one lane in each direction, with a dashed yellow centerline
separating opposing traffic. Ramona Boulevard has a posted speed limit of 30 MPH. Parking is
restricted to no stopping anytime on the north side of Ramona Boulevard and is restricted from
6:00 AM to 10:00 AM on Thursdays on the south side due to street sweeping. Land use through
this segment of Ramona Boulevard is Single Family Residential on the south with the Interstate
10 Freeway on the north.
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 3 -year period between August 2020 through August
2022 (available data at the time of traffic review). A review of available collisions that were
reported to SWITRS along the segment of Ramona Boulevard was conducted. Based on the
Collision History Analysis, investigation, and data, it was determined that there were 3 total
collisions reported.
Average Daily Traffic (ADT) data was obtained from counts taken on September 29th, 2021 for
Ramona Boulevard between Burton Avenue and Rosemead Boulevard. All counts were taken
when schools were open and back in session. It was determined that there were a total of
approximately 3,460 vehicles per day (vpd).
To assess the speed at which vehicles are traveling along Ramona Boulevard, speed samples were
taken over a 24-hour period on September 29th, 2021. The 85th percentile speed of vehicles along
Ramona Boulevard was determined to be at 38 mph. This translates to mean that 85 percent of the
vehicles sampled are traveling at 38 mph or below which is above the speed limit of 30 mph. Table
3 below shows the September 29th, 2021, speed survey results.

TRAFFIC CALMING DEVICES AND STRATEGIES
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 Ramona Boulevard between Burton Avenue and Rosemead
Boulevard. At this time the City of Rosemead does not have a Speed Hump Policy in place. Speed humps
are usually only installed on roadways that meet certain criteria such as being classified as a local street

TRAFFIC REVIEW ON RAMONA BOULEVARD BETWEEN BURTON AVENUE TO THE 1-10 EB OFF RAMPS/ROSEMEAD BOULEVARD
with minimum and maximum vehicles per day as well as posted speed limits of 25 mph or less. Using this
criteria Ramona Boulevard would not be eligible for installation of speed humps.
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
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
1) Traffic Education Campaign: This consists of flyers, neighborhood meetings, banners and other
notices to assist in 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"06" for stop signs and 30"x36" for speed limits.
Table 2B-1. Regulatory Sign and Plague Sizes (Sheet 1 of 4)
5) Radar Feedback Signs: Radar feedback signs are an effective way to alert Drivers of their speed. The
speed of each passing vehicle is taken and displayed next to the posted speed limit.
Targeted Police Enforcement: The police department deploys officers to perform enforcement on
residential streets for at least an hour a day.

TRAFFIC REVIEW ON RAMONA BOULEVARD BETWEEN BURTON AVENUE TO THE 1-10 EB OFF RAMPS/ROSEMEAD BOULEVARD
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 Ramona Boulevard between Burton
Avenue and Rosemead Boulevard would benefit from a combination of Traffic Calming Measures. The
improvements are listed below and shown on the installation exhibit.
1. INSTALL NEW OVERSIZED SPEED LIMIT SIGN AND PAVEMENT LEGEND: Install new Oversized
Speed Limit (112-1) Sign and Pavement legend, approximately 150 -feet west of Ramona Boulevard
and Barton Avenue intersection for eastbound traffic on existing light pole. (PerCAMUTCDSection
2B.13 and CAMUTCD Table 2B-1.)
2. INSTALL "CROSS TRAFFIC DOES NOT STOP" (W4 -4P) PLAQUES ON EXISTING STOP SIGNS: Add
"Cross Traffic Does Not Stop" (W4 -4P) Plaques to existing Stop Signposts at side streets that
intersect with Ramona Boulevard.
• Install "Cross Traffic Does Not Stop" Plaque to Existing Stop Signposts at the intersections
of Ramona Boulevard and Bartlett Avenue, Ramona Boulevard and Muscatel Avenue, and
Ramona Boulevard and Ivar Avenue.
3. REMOVE AND REPLACE EXISTING SPEED LIMIT SIGN WITH NEW OVERSIZED SPEED LIMIT SIGN:
Remove and Replace existing 30 -MPH Speed Limit Sign (R2-1) with oversized Speed Limit Sign and
Pavement Legend for westbound traffic on Ramona Boulevard. (Per CAMUTCD Table 2B-1). Sign
should be posted at least 8' high so that it does not hang over into the street and passing vehicles
would not strike the sign since there is a tall sound wall on the north side of Rosemead Boulevard.
Also add pavement legends opposite the speed limit sign.
4. INSTALL WHITE SIDE STRIPE 8 feet from curb with an angled diagonal stripe to denote this is a
parking lane not another travel lane on the south side of Ramona Boulevard from Burton Avenue
to Ivar Avenue. This stripe will visually narrow the roadway to help slow speeding traffic.
5. REMOVE THE 35MPH SPEED LIMIT SIGN under the curve sign at the 1-10 EB Ramp and replace
with 20 MPH sign warning sign
6. ADD NEW W1-8 CHEVRONS (BI-DIRECTIONAL) along the metal barricades at the curve east of
Ivar Avenue. Remove old OM1 -3 reflectors. A set of 3 W1-8 signs posted back-to-back in highly
reflective neon yellow. (post at the beginning, end and in the middle of the metal barricade.)
7. ADD YELLOW RPMS IN THE CENTER YELLOW STRIPE in the curve so that the curve is more visible
to motorists at night. Approximately 150 feet.

difficult due to Caltran's design standards for lane width being more restrictive that most cities

4. NEW BUSINESS
A. TRAFFIC REVIEW ON RAMONA BOULEVARD BETWEEN BURTON AVENUE TO THE
1-10 EB OFF RAMPSIROSEMEAD BOULEVARD
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 resident requested the City to evaluate the installation
of speed humps along the segment of Ramona Boulevard from Burton Avenue to Rosemead
Boulevard.
Traffic Engineer Robbins explained as part of the traffic review, engineering staff looked at the
existing roadway conditions, a review of approximately 3 years of available collision data, an
average daily traffic count (ADT), a 24-hour speed survey as well as an examination of existing
field conditions. On behalf of the City of Rosemead, Traffic Engineer Robbins provided
recommendations for a combination of traffic calming measures that include the installation of
oversized speed limit signs, installing striping and pavement markers, removing the 35 MPH speed
limit sign under the curve sign at the 1-10 EB ramp and replace with 20 MPH sign, install chevron
signs along the metal barricades at the curve east of Ivar Avenue, as well as warnings placed
under the existing signposts alerting drivers that CROSS TRAFFIC DOES NOT STOP at the
intersection of Ramona Boulevard and Bartlett Avenue, Ramona Boulevard and Muscatel Avenue,
and Ramona Boulevard and Ivar Avenue.
Chair Drange opened the public comment period.
The City received a Public Comment via email from Jeff Che expressing gratitude towards the
Traffic Commission and City staff for implementing the traffic calming measures at the intersection
of Ramona Boulevard and Burton Avenue. The resident agreed with the proposed staff
recommendations for Ramona Boulevard between Burton Avenue and Rosemead Boulevard.
Chair Drange closed the public comment period.
Rosemead Traffic Commission Meeting
Minutes of November 3, 2022
Page 2 of 7
Commissioner Lang asked if the proposed recommendation to install white side striping would
remove parking.
Traffic Engineer Robbins responded it would not remove parking space and the purpose of the
white side stripes is to visually narrow the street.
Chair Drange commented that he rides his bicycle on this street frequently and noticed the lane
closer to the freeway is narrower than the other lane. He asked with the proposed
recommendations, what would be the width of the lane on the north side and the width of the lane
of the south side.
Traffic Engineer Robbins replied that the south side lane is about 22 feet and the north side lane is
about 13 feet. With 8 feet for parking, that would leave 12 feet for the eastbound lane. If the lanes
were made equal, it would make it more convenient for bicyclist, however, it would not assist with
the lane narrowing.
Commissioner Lang commented he agrees with the recommendation to add chevrons signs along
the metal barricades at the curve and asked if there is a process for the City to review and install
those signs without having a resident bring it up.
City Engineer Chan commented that the portion of Ramona Boulevard next to the freeway off ramp
may be within Caltrans jurisdiction and may require the City to obtain a permit through Caltrans to
make any changes to the configuration.
Commissioner Lang asked if there was a general process to remove outdated signs or update
signs that are not within Caltrans jurisdiction.
City Engineer Chan replied yes and if it were not within Caltrans area, we would not need to go
through them.
Traffic Engineer Robbins commented that usually when the City is performing their pavement
management, the field crew would note any outdated signs that need to be replaced as long as it is
not a regulatory sign.
City Engineer Chan commented that we can also submit a service request through the Caltrans
portal.
Chair Drange asked when it comes time to repave this portion of the road if there is a mechanism
to make sure to include moving the centerline slightly over if requested.
City Engineer Chan replied there is a process for shifting centerlines which involves land surveyors
and submitting centerline ties to county to be approved and recorded.
Chair Drange asked if this agenda item is approved as is if there is a way to record or remember to
assess the centerline when the time comes.
Rosemead Traffic Commission Meeting
Minutes of November 3, 2022
Page 3 of 7
Traffic Engineer Robbins replied the City has a pavement management program which usually list
all the streets in the city and their time frame as to when they are slated for repavement. We would
have to look at the pavement plan to see when Ramona Boulevard is to be repaved. If it is years
from now, staff would likely have to remind the City when it comes due. We also have the meeting
minutes to refer to.
Chair Drange asked if we are generally apprised of repaving schedules.
Traffic Engineer Robbins replied that it may just go to city council.
Commissioner Hermosillo made a motion, seconded by Vice Chair Nguyen, to approve staff
recommendations. Vote resulted in:
Yes: Hermosillo, Lang, Quintanilla, Nguyen, Drange
No: None
Abstain: None
Absent: None
B. RED CURB REVIEW AT 7430 GARVALIA 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 resident requested the City to evaluate installation of
red curb due to reported parked vehicles encroaching into the resident's driveway path, resulting in
the parked vehicle hanging over and blocking their driveway access.
Traffic Engineer Robbins explained as part of the traffic review, engineering staff looked at the
existing roadway conditions, as well as an examination of existing field conditions. On behalf of the
City of Rosemead, Traffic Engineer Robbins recommended that red curb should be installed on
either side of the request curb location on the driveway aprons, often referred to as "red tipping."
Vice Chair Nguyen commented that it likely would not deter a regular sized vehicle from parking
there unless there was constant patrolling.
Commissioner Hermosillo asked how the parking conditions on the street is.
Traffic Engineer Robbins replied there is some multi -family across the street so parking can be
heavy during the weekends and afterhours. During the weekday parking is scattered. The street is
not as dense as other streets, but parking can be heavy.
Commissioner Quintanilla asked if the City has guidelines or a policy on painting driveway aprons
Traffic Engineer Robbins replied residents have to fill out a curb marking request application. The
resident for this address submitted the application and it met the criteria for further review.
Rosemead Traffic Commission Meeting
Minutes of November 3, 2022
Page 4 of 7
City Engineer Chan commented if the resident notices a car is encroaching into their driveway
approach, they could submit a request for the City to review it.
Traffic Engineer Robbins mentioned that there is a curb marking policy and procedures and
explained the process for driveway red tipping.
Chair Drange asked to clarify what it means when the policy states "striped appropriately."
Traffic Engineer Robbins explained the striping is referring to the painting of the curb.
Commissioner Quintanilla asked if we know how many other areas in the city are similar to this with
non-standard parking space.
City Engineer Chan replied there are a few throughout the city.
Chair Drange asked if it the parking space between two driveways was more than the 18 feet
indicated in the policy for non-standard parking space, would it be eligible for driveway red tipping,
Traffic Engineer Robbins replied if the applicant is able to prove that cars are overhanging into their
driveway, for example having two cars parking in a 25 foot space, they could still request for the
driveway red tipping.
Traffic Engineer Robbins explained the commission would need to decide whether to paint the curb
as proposed in the recommendation or to paint the whole curb red.
Commissioner Lang suggested we should revisit this item in 3 to 6 months to see if the resident is
content with the recommendation.
Chair Drange asked if it was one car or two cars parking in the space. He also commented he is
inclined to paint the whole curb red as the red tipping would likely not deter a car from parking
there unless there is enforcement.
Traffic Engineer Robbins mentioned the applicant did not mention specifically if it was one or two
cars.
Commissioner Lang referred to the proposed diagram which indicates the curb to be approximately
10 feet with 4 feet 10 inches of driveway apron on one side and 4 feet of driveway apron the other
side. He asked how long a sedan car is.
Traffic Engineer Robbins replied about 12 or 13 feet.
Commissioner Lang commented a parked car would be clearly encroaching the red curb.
Commissioner Quintanilla asked if we have enforcement records of cars encroaching red curb.
Traffic Engineer Robbins replied we do not have those records.
Rosemead Traffic Commission Meeting
Minutes of November 3, 2022
Page 5 of 7
Vice Chair Nguyen commented their discussion on the red curb suggest the commission feels cars
would still park normally even with red tipping and would be inclined to paint the whole curb red.
Commissioner Hermosillo agreed with Vice Chair Nguyen to paint the whole curb red.
Commissioner Quintanilla asked what the purpose is for painting the driveway aprons if 10 feet of
curb is going to be painted red.
Traffic Engineer Robbins replied it just makes it more obvious, however, it is not necessary if you
are already going to paint the 10 feet curb space red.
Commissioner Lang agreed with Commissioner Quintanilla's approach of not painting the driveway
apron because it does not look visually appealing.
Commissioner Hermosillo agreed to amend the recommendation to have only the 10 feet curb
space painted red.
Vice Chair Nguyen made a motion, seconded by Commissioner Hermosillo, to change staff
recommendation to install red curb for the 10 feet curb portion. Vote resulted in:
Yes: Hermosillo, Lang, Quintanilla, Nguyen, Drange
No: None
Abstain: None
Absent: None
5. MATTERS FROM STAFF None
6. COMMISSIONER REPORTS
Commissioner Quintanilla reported an unsafe condition on the roadway at Glendon Way where it
meets Rosemead Boulevard, going eastbound on Glendon Way, and adjacent to the UFC Gym.
When going eastbound on Glendon Way, as you approach the interstate pavement marking, you
have the option to either turn right onto the freeway on-ramp or go straight to make a left turn.
When you are on the left turn lane, the centerline is faded. Cars coming southbound on Rosemead
Boulevard wanting to make a left onto the freeway on-ramp are making wide turns thinking there
are two lanes, but it is actually the lane for eastbound cars. The pavement markings in the area
need to be refreshed.
City Engineer Chan replied staff can look into it. He also mentioned that intersection, the on and off
ramp at Rosemead Boulevard and interstate 10 freeway is planned to be reconfigured in a future
project.
Chair Drange commented a lot of people when driving eastbound on Glendon Way as they
approach the interstate pavement marking, they go straight because they do not want to make a
right onto the freeway.
