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 of Dorothy Street and Brighton Street ANALYSIS The traffic review included an analysis of the existing roadway conditions, a field review at the Duff Language Magnet Academy, and a review of approximately 3-years of available collision data. City Traffic Commission Meeting August 6, 2026 Page 2 of 5 Existing Conditions: Dorothy Street runs east and west, and is considered a local road per the California Road Functional Classification by Caltrans. Dorothy Street has a posted speed limit of 25 MPH. Dorothy Street is approximately 38-feet wide, with one lane of travel in each direction and a no marked center line. Along Dorothy Street at the intersection with Brighton Street, the street width narrows with a bulb out at the west leg crosswalk area to 28-feet wide, and a double yellow line is marked 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. City Traffic Commission Meeting August 6, 2026 Page 4 of 5 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.

Brighton St CROSSING GUARD REVIEW FOR DOROTHY STREET AND BRIGHTON STREET CITY OF ROSEMEAD Prepared By: Transtech Engineers, Inc. | Page 15 of 32 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. CROSSING GUARD REVIEW FOR DOROTHY STREET AND BRIGHTON STREET CITY OF ROSEMEAD Prepared By: Transtech Engineers, Inc. | Page 16 of 32 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 necessarily consecutive) daily use the crossing while going to or from school? Whenever the critical (85th percentile) approach speed exceeds 40 mph, the guidelines for rural areas should be applied. 30 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. X X Uncontrolled crossings where there is no alternate controlled crossing within 600 feet? Del Mar Avenue is approximately 400’ from Brighton Street. X 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? Figures 4 thru 8 illustrate vehicle approach volume, none of the peak count time exceeded the minimum approach volume threshold. X 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?

Where justified through analysis of the operations of the intersection N/A N/A CROSSING GUARD REVIEW FOR DOROTHY STREET AND BRIGHTON STREET CITY OF ROSEMEAD Prepared By: Transtech Engineers, Inc. | Page 17 of 32 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.
