A. Crossing Guard Review for the Intersection at Dorothy Street & Brighton Street, for the Duff
Language Magnet Academy
SUMMARY
The City of Rosemead received a request regarding the addition of an adult crossing guard for the Duff
Language Magnet Academy, at the intersection at Dorothy Street and Brighton Street. The request reported
concerned for students and residents in the community crossing the intersection at Dorothy Street and
Brighton Street and asked that improvements be installed in the area. This intersection is stop controlled for
southbound, and there are existing crosswalks at the north leg and west leg of the intersection. In response
to this request and on behalf of the City, engineering staff has completed a traffic review of this intersection
at Dorothy Street and Brighton Street. The traffic review included a review of existing conditions, 3 -years of
available collision data, Average Daily Traffic (ADT) counts, 24-hour speed survey, Turning Movement
Counts, Pedestrian Movement Counts, and field observations at the intersection.
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,
it was determined that the intersection of Dorothy Street and Brighton Street would benefit from the installation
of traffic devices at the intersection, to improve the overall visibility along Dorothy Street at Brighton Street. It
was also determined that based on engineering judgment, as well as observations and counts gathered during
the field review, a crossing guard is recommended for Dorothy Street and Brighton Street.
CEQA: Not subject to the California Environmental Quality Act.

A. All-Way Stop Requests for the Intersections of Graves Avenue at Gladys Avenue & Graves
Avenue at Charlotte 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 request to review the intersections of Graves
Avenue at Charlotte Avenue and Graves Avenue at Gladys Avenue, to determine if the intersections qualify
for the installation of an all-way stop. The request is to implement traffic calming measures along this segment
of Graves Avenue, due to concerns of speeding vehicles observed along the street. The resident expressed
concern for other drivers and pedestrians in the area. In response to this request, and on behalf of the City,
engineering staff has completed a traffic review at the subject intersections. The traffic review included a
review of existing conditions of the segment, 3-years of available collision data, Average Daily Traffic (ADT)

counts and 24-hour speed survey counts, and a field review of existing conditions along Graves Avenue at
Charlotte Avenue and Graves Avenue at Gladys Avenue.
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 segment of Graves Avenue between San Gabriel Boulevard and Angelus Avenue was found
to qualify for the installation of additional traffic calming measures.
Vice-Chair Nguyen asked about the potential ramifications if the City were to install a four-way stop at either
Gladys Ave or Charlotte Ave.
Associate Engineer Richter responded that, because the locations do not meet the required engineering
warrants, the City could face liability in the event of an accident if a stop sign were installed contrary to the
traffic data and engineering recommendations.
Commissioner Trieu asked whether a crosswalk crossing Graves Ave at either Gladys Ave or Charlotte Ave
had been considered.
Associate Engineer Richter asked for clarification regarding the proposed crosswalk location.
Commissioner Trieu clarified that he was referring to crosswalks along Graves Ave at the mid-block
locations near Gladys Ave and Charlotte Ave.
Associate Engineer Richter replied that a mid-block crosswalk at those locations would likely not be
recommended based on the current traffic volumes and pedestrian counts. She explained that such
requests require additional review and must meet state standards, which typically include a significant
number of pedestrian crossings. Based on the preliminary counts collected, there were not enough students
crossing to meet those criteria. She further noted that mid-block crosswalks require sufficient visibility for
approaching vehicles. One concern at this location is the slight downhill grade and curve along the west side
of Graves Ave near San Gabriel Blvd. Vehicles traveling downhill may not have adequate time to react to a
crosswalk located mid-block. While the City could further evaluate the request, it would not currently be
recommended based on the available information.
Commissioner Trieu agreed, however, he expressed that additional monitoring or potential improvements
may still be beneficial, as drivers traveling eastbound or westbound on Graves Ave may be more inclined to
speed when there are no stop signs present.
Chair Drange does not think crosswalks would be beneficial at that location. He asked if there was a
crosswalk crossing Graves Ave at Angelus Ave.
Associate Engineer Richter confirmed there is an existing crosswalk at Graves Aves and Angelus Ave on
the west leg and north leg. She added that there is a crossing guard near the school as well.
Commissioner Tran asked if there are alternative solutions to help slow down vehicles.
Associate Engineer Richter discussed several potential measures to address the concern, including the
installation of rumble strips. She noted that the speed survey did not indicate a significant speeding issue,
with the 85th percentile speed recorded at 32 mph compared to the posted speed limit of 25 mph. As an
initial measure, she recommended installing additional speed limit signs and monitoring conditions. Staff

could revisit the location approximately six months after installation to evaluate the effectiveness of the
signage and determine whether additional traffic calming measures are warranted.
Chair Drange asked if there are any existing speed limit signs.
Associate Engineer Richter replied there are no existing speed limit signs.
Commissioner Tran mentioned AB 413 and asked if that was something considered.
Associate Engineer Richter stated that extending the red curb was considered. Because the location is
adjacent to a fire hydrant, the red curb could be extended to 20 feet as part of routine maintenance. She
noted that extending red curbs at every intersection under the new legislation would significantly increase
red curb markings throughout the City. The decision to extend the red curb at this location would ultimately
be at the City's discretion.
Commissioner Tran made a motion, seconded by Vice-Chair Nguyen, to approve staff
recommendations, and revisit this item in six months to evaluate its effectiveness and determine
whether any additional measures are warranted. Vote resulted in:
Yes: Drange, Nguyen, Lang, Tran, Trieu
No: None
Abstain: None
Absent: None
Director of Public Works Gutierrez stated that invitations had been sent to both the Traffic Commission and
Beautification Commission for a joint special meeting regarding a project that requires input from both
commissions.
City Engineer Basilyous explained that the City is undertaking a roadway improvement project along Walnut
Grove Avenue and Valley Boulevard, which includes street resurfacing, ADA curb ramps, sidewalks, and
other infrastructure improvements. As part of the project, the City is also conducting feasibility studies for
bike lanes and raised medians. The City Council approved the project for design and directed staff to
present the completed feasibility studies to the Traffic Commission and Beautification Commission for
review and feedback.
Chair Drange asked whether the joint meeting would be agendized with a quorum of both commissions or
held for informational purposes only.
Director of Public Works Gutierrez responded that the meeting structure has not yet been finalized but
confirmed it will be a joint meeting with both commissions in attendance. He then asked the commissioners
to provide their availability, and the Commission agreed that either April 29 or April 30 would work for the
meeting.

for approximately 50-feet on either side of the intersection on Dorothy Street. Parking along the
north and south side of Dorothy Street is allowed, except where the curbs are marked red and on
Mondays between 6AM-7AM. This segment of Dorothy Street runs parallel to single-family
residential homes, and a commercial area on the north side of the street. On the south side of
Dorothy Street, the street segment runs parallel to the Duff Language Magnet Academy, Garvey
Park, and a commercial area. There area yellow ladder crosswalks marked on the west leg and
north leg of the intersection at Dorothy Street and Brighton Street. At the west leg of the
intersection along Dorothy Street, there are pedestrian crossing signs and down arrows adjacent to
the crosswalk.
Brighton Street runs north and south, and is considered a local road per the California Road
Systems May by Caltrans. Brighton Street has a prima facie speed limit of 25 MPH. Brighton
Street is approximately 40-feet wide, with one lane in each direction and has no marked centerline.
Parking is available on the east and west side of Brighton Street, except where the curb is marked
red and during street sweeping times on Mondays between 10AM-2PM. This segment of Brighton
Street north of the intersection with Dorothy Street is adjacent to single-family residential homes
located on both sides of the street. There are yellow ladder crosswalks marked on the north leg and
west leg of the intersection of Brighton Street at Dorothy Street.
Duff Language Magnet Academy is located along Dorothy Street. Duff Language Magnet
Academy is a public elementary school within the Garvey School District and serves an average
of 335 students in grades kindergarten through sixth grade. The regular bell schedules for
students at Duff Language Magnet Academy are as follows: Monday through Friday – Start
time: 8:20am for all students, End time: 2:35pm for all students; Wednesdays early dismissal at
1:35pm for all students. There are existing yellow ladder crosswalks at the intersection of
Dorothy Street and Brighton Street at the west leg, which has school signage, and at the north leg
of the intersection, at the school frontage of Duff Language Magnet Academy.
BACKGROUND INFORMATION:
This location of Dorothy Street at Brighton Street, adjacent to the Duff Language Magnet
Academy, was previously reviewed in 2023 to review a request for a crossing guard to be
installed adjacent to the school. At the time of the initial review, the Duff Language Magnet
City Traffic Commission Meeting
August 6, 2026
Page 3 of 5
Academy served approximately 215 students in grades K-4. Vehicle and pedestrian counts data
was collected along the segment of Dorothy Street, as well as at the intersection of Dorothy
Street and Brighton Street, to determine the number of vehicles and pedestrians traveling through
the area. At the time, the location did not meet the requirements for a crossing guard to be placed
at the intersection of Dorothy Street and Brighton Street, based on the criteria from the
CAMUTCD. In 2023, was determined that there was not enough pedestrian and vehicular
activity at the subject location to warrant a crossing guard to be placed at the intersection.
However, at the time of the initial review, the Duff Language Magnet Academy was in the
process of expanding the student population and grade levels, from K-4th Grade to K-6th Grade.
The student body was expected to expand by two grade levels for the Fall 2025/Spring 2026
academic school year. It was determined that a secondary review be completed for Fall
2025/Spring 2026, after the school added two grades to the student population.
Currently, the Duff Language Magnet Academy serves approximately 335 students in grades K-
6th Grade, which higher than the approximate 215 students in grades K-4th Grade served in the
Fall 2022/Spring 2023 academic school year. The data collected from the previous review was
compared to the new data in the current review, and it was determined that there are higher
number of pedestrians and vehicles traveling through this area. This is based on the counts
collected during the 2025/2026 academic school year, as compared to the previous counts from
the 2022/2023 academic school year. Given the higher number of students attending the school,
due to the expansion of grades added to the Duff Language Magnet Academy, a crossing guard
would facilitate student crossings at the intersection of Dorothy Street and Brighton Street.
Following the most recent review completed for the Duff Language Magnet Academy, it was
determined that based on engineering judgement, a crossing guard may be placed at the
intersection of Dorothy Street and Brighton Street. Given the higher number of students
attending the school, due to the expansion of grades added to the Duff Language Magnet
Academy, a crossing guard would facilitate student crossings at the intersection of Dorothy
Street and Brighton Street.
Based on the crossing guard criteria from the CAMUTCD and breakdown table shown in the
Traffic Report (Attachment A), it can be determined that this intersection of Dorothy Street and
Brighton Street, although does not meet both hours with 40 school age pedestrians, would benefit
from a crossing guard. It is our recommendation that a crossing guard would benefit this
intersection by providing an additional safety measure for parents to allow students to cross, as
well as increase the number of students using the marked crosswalks by allowing students to
cross the west leg of the intersection during the heavier traffic times of student drop off/pickup
along Dorothy Street.

STAFF RECOMMENDATION
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, it was determined that the intersection of Dorothy Street and
Brighton Street would benefit from the installation of traffic devices at the intersection, to improve
the overall visibility along Dorothy Street at Brighton Street. It was also determined that based on
engineering judgment, as well as observations and counts gathered during the field review, a
crossing guard is recommended for Dorothy Street and Brighton Street.
The Duff Language Magnet Academy may also consider the addition of educational pamphlets
and/or community outreach programs to the parents and students of Duff Language Magnet
Academy, regarding the placement of a crossing guard at the intersection of Dorothy Street and
Brighton Street. Based on the field observations completed at the school, there were several
instances of adults and students crossing the street midblock both east and west of the subject
intersection. The school may consider providing educational tools on using the crosswalk with the
crossing guard, and reduce the number of midblock crossings where there is vehicular traffic along
Dorothy Street.
It is important to note that some improvements were installed along this area of Dorothy Street
and Brighton Street following the first review of this area in the Fall 2022/Spring 2023 school
year. This included pedestrian crossing signage with downward facing arrows at the west leg of
the intersection along Dorothy Street at Brighton Street, as well as some added school signage.
Some additional improvements are recommended to improve the overall visibility at the
intersection of Dorothy Street and Brighton Street.
Please refer to the Installation Exhibit in Attachment A for a conceptual exhibit representation
of the proposed recommendations. These improvements include:
1. INSTALL CROSSING GUARD: Install a Crossing Guard at the northwest corner of the
intersection of Dorothy Street and Brighton Street for students crossing the north leg and
west leg of the intersection, adjacent to Duff Language Magnet Academy. The installation
of a crossing guard at the intersection will help student age pedestrians cross the street along
Dorothy Street, as well as along Brighton Street, during student drop off and pickup times
from the school.
2. REFRESH CROSSWALKS: Refresh the existing crosswalks at the north leg and west leg
of the intersection of Dorothy Street and Brighton Street, to improve the overall visibility
for vehicles and pedestrians at the intersection.

The counts shown above in Table 5, collected on June 2, 2026, only encompassed the morning and
afternoon periods for student drop off/pickup, corresponding with the bell schedule for the Duff
Language Magnet Academy. In order to ensure that the counts were completed before school was out
for the summer break, the critical times of 7AM-9AM and 1PM-3PM were focused on for data collection,
to reflect the drop off and pickup times for students. The total number of pedestrians crossing per hour
are shown in the table above.
As part of the review for pedestrians crossing at the intersection of Dorothy Street and Brighton Street,
an in-person observation as well as pedestrian count was carried out on Tuesday, June 2, 2026, during

FIELD OBSERVATIONS AT BRIGHTON STREET AND DOROTHY STREET
An observation was completed in the morning and afternoon on Tuesday, June 2, 2026, at the
intersection of Dorothy Street and Brighton Street, located north of Duff Language Magnet Academy, an
elementary school in the City of Rosemead. The observations were conducted during school drop off
and pickup times for Duff Language Magnet Academy students, to determine if there is a need for a
crossing guard to be installed at the intersection of Dorothy Street and Brighton Street. During the field
review, vehicular traffic movements were observed along Dorothy Street and Brighton Street during the
morning and afternoon drop off and pickup times for students. It was determined that there was more
traffic during the morning in this area, due to the number of students being dropped off at school. A
backup of cars was observed along Dorothy Street for westbound traffic on the south side of the street,
as vehicles would queue along the curb on Dorothy Street to drop off students.

During the field review, it was observed that there were several cars parking along the north side of
Dorothy Street, as well as along Brighton Street, so parents could walk their students to the school
entrance along Dorothy Street. The majority of pedestrians used the marked crosswalks at the
intersection of Dorothy Street and Brighton Street when crossing the street, however some parents and
students would cross the street midblock along Dorothy Street between Del Mar Avenue and Brighton
Street. The peak time for traffic along Dorothy Street and Brighton Street was for approximately 10
minutes before the school started at 8:20AM.
It was also observed that some parents would park in the parking spaces along the south side of Dorothy
Street in front of Garvey Park during student drop off and pickup, and walk their students to and from
the school entrance along the south side of the street on the sidewalk. It was also observed that some
drivers would stop in the middle of the street (double parking) along Dorothy Street, to drop off or
pickup students during school drop off/pickup times.

CRITERIA FOR DETERMINING IF A CROSSING GUARD IS WARRANTED
The City of Rosemead received a request to review the intersection of Dorothy Street and Brighton Street
and determine if the installation of a crossing guard is warranted. The intersection of Dorothy Street and
Brighton Street is located north of Duff Language Magnet Academy. The intersection at Dorothy Street
and Brighton Street is stop controlled for southbound traffic, and has marked yellow ladder crosswalks on
the north leg and west leg of the intersection. There is an uncontrolled pedestrian crosswalk at the west
leg of the intersection. Duff Language Magnet Academy serves students in grades K-6. As a result of the
initial request, the City commissioned a Traffic Engineering study to assess existing conditions as well as
determine if a crossing guard is warranted.
All Engineering studies and recommendations follow the guidelines found in the CAMUTCD (California
Manual on Uniform Traffic Control Devices) and the California Vehicle Code. Following engineering
standards assures that all devices or measures placed in or on public streets have a universal meaning and
all drivers understand and can anticipate where signs or striping may be placed. This is also true in regard
to the criteria for Adult Crossing Guards. This traffic study is based on the guidelines found in the California
Manual on Uniform Traffic Control Devices (CAMUTCD), California Vehicle Code (CVC), and based on
engineering judgement from a detailed traffic study.
Criteria for Adult Crossing Guards
Adult Crossing Guards normally are assigned where official supervision of school pedestrians is desirable
while they cross a public highway, and at least 40 school pedestrians for each of any two hours (not
necessarily consecutive) daily use the crossing while going to or from school. Table 6 outlines the criteria
and findings. As found in the CAMUTCD 7D.02 the following guidelines are provided.
Adult crossing guards may be used under the following conditions:
1. Adult Crossing Guards normally are assigned where official supervision of school pedestrians is
desirable while they cross a public highway, and at least 40 school pedestrians for each of any
two hours (not necessarily consecutive) daily use the crossing while going to or from school.
2. At uncontrolled crossings where there is no alternate controlled crossing within 600 feet; and
a. In urban areas where the vehicular traffic volume exceeds 350 during each of any two hours
(not necessarily consecutive) in which 40 or more school pedestrians cross daily while
going to or from school; or
b. In rural areas where the vehicular traffic volume exceeds 300 during each of any two hours
(not necessarily consecutive) in which 30 or more school pedestrians cross daily while
going to or from school. Whenever the critical (85th percentile) approach speed exceeds 40
mph, the guidelines for rural areas should be applied.
3. At stop sign-controlled crossing: Where the vehicular traffic volumes on undivided highways of
four or more lanes exceeds 500 per hour during any period when the school pedestrians are
going to or from school.
4. At traffic signal-controlled crossings:
a. Where the number of vehicular turning movements through the school crosswalk exceeds
300 per hour while school pedestrians are going to or from school; or
b. Where justified through analysis of the operations of the intersection.

Based on the crossing guard criteria from the CAMUTCD and breakdown table above, it can be
determined that this intersection of Dorothy Street and Brighton Street, although does not meet both
hours with 40 school age pedestrians, would benefit from a crossing guard. It is our recommendation
that a crossing guard would benefit this intersection by providing an additional safety measure for
parents to allow students to cross, as well as increase the number of students using the marked
crosswalks by allowing students to cross the west leg of the intersection during the heavier traffic times
of student drop off/pickup along Dorothy Street.
Table 6: Summary of Criteria for Adult Crossing Guard Conditions
(Refer to Pedestrian Tables 4, 5, and 6) YES NO
At least 40 school pedestrians for each of any two hours (not

school age pedestrians crossing. Table 6 shows that school age
pedestrians meet the volume threshold at 7:45 to 8:45am and it is
estimated that additional pedestrians would use the crossing if
controlled by a crossing guard. This may reduce the number of parents
dropping students off by car.

BACKGROUND INFORMATION:
This location of Dorothy Street at Brighton Street, adjacent to the Duff Language Magnet Academy, was
previously reviewed in 2023 to review a request for a crossing guard to be installed adjacent to the
school. At the time of the initial review, the Duff Language Magnet Academy served approximately 215
students in grades K-4. Vehicle and pedestrian counts data was collected along the segment of Dorothy
Street, as well as at the intersection of Dorothy Street and Brighton Street, to determine the number of
vehicles and pedestrians traveling through the area. At the time, the location did not meet the
requirements for a crossing guard to be placed at the intersection of Dorothy Street and Brighton Street,
based on the criteria from the CAMUTCD. In 2023, it was determined that there was not enough
pedestrian and vehicular activity at the subject location to warrant a crossing guard to be placed at the
intersection.
However, at the time of the initial review, the Duff Language Magnet Academy was in the process of
expanding the student population and grade levels, from K-4th Grade to K-6th Grade. The student body
was expected to expand by two grade levels for the Fall 2025/Spring 2026 academic school year. It was
determined that a secondary review be completed for Fall 2025/Spring 2026, after the school added two
grades to the student population.
Currently, the Duff Language Magnet Academy serves approximately 335 students in grades K-6th Grade,
which higher than the approximate 215 students in grades K-4th Grade served in the Fall 2022/Spring
2023 academic school year. The data collected from the previous review was compared to the new data
in the current review, and it was determined that there are higher number of pedestrians and vehicles
traveling through this area. This is based on the counts collected during the 2025/2026 academic school
year, as compared to the previous counts from the 2022/2023 academic school year. Given the higher
number of students attending the school, due to the expansion of grades added to the Duff Language
Magnet Academy, a crossing guard would facilitate student crossings at the intersection of Dorothy
Street and Brighton Street.
RECOMMENDATIONS
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, it was determined that the intersection of Dorothy Street and Brighton Street would benefit
from the installation of traffic devices at the intersection, to improve the overall visibility along Dorothy
Street at Brighton Street. It was also determined that based on the existing conditions and vehicle
counts along Dorothy Street and Brighton Street, the requirements for the installation of a crossing
guard were met. At this time, a crossing guard is recommended for Dorothy Street and Brighton Street.
The Duff Language Magnet Academy may also consider the addition of educational pamphlets and/or
community outreach programs to the parents and students of Duff Language Magnet Academy,
regarding the placement of a crossing guard at the intersection of Dorothy Street and Brighton Street.
Based on the field observations completed at the school, there were several instances of adults and
students crossing the street midblock both east and west of the subject intersection. The school may
consider providing educational tools on using the crosswalk with the crossing guard, and reduce the
number of midblock crossings where there is vehicular traffic along Dorothy Street.
