STAFF REPORT
TO: THE HONORABLE MAYOR AND CITY COUNCIL
FROM: BEN KIM, ACTING CITY MANAGER 1 �
DATE: MARCH 22, 2022
SUBJECT: APPROVAL OF THE TRAFFIC COMMISSION RECOMMENDATIONS
FOR TRAFFIC IMPROVEMENTS AT THE INTERSECTION OF
MISSION DRIVE AND DELTA AVENUE
SUMMARY
At the February 3, 2022, Traffic Commission Meeting, staff presented recommendations to
improve the existing roadway conditions at the intersection of Mission Drive and Delta Avenue.
After discussion and presentation of the item, the Traffic Commission approved the staff
recommendations for the area. Public Works Field Services staff will be able to complete all the
recommended items. If necessary, additional materials and supplies may be purchased at a minimal
expense to complete the recommended work and staff would utilize the approved Fiscal Year
2021-2022 Traffic Signs and Markers available funds.
BACKGROUND
Staff completed a traffic review and recommended appropriate traffic measures at the intersection
of Mission Drive and Delta Avenue.
The City received a resident request to review the line of sight and existing conditions at the
intersection of Mission Drive and Delta Avenue. In response to this request and on behalf of the
City, staff completed a traffic review and recommended appropriate curb markings and traffic
measures along Mission Drive to increase visibility for drivers turning left onto Mission Drive
from Delta Avenue. The resident reported that citizens making a left-hand turn from Delta Avenue
onto Mission Drive have an obstructed view due to parked vehicles along Mission Drive. The
installation of red curb along Mission Drive would improve overall visibility for drivers at the
intersection.
After a thorough review of existing field and traffic conditions and per the guidelines in the
AGENDA ITEM 5.G
City Council Meeting
March 22, 2022
Page 2 of 3
California Manual on Uniform Traffic Control Devices (CAMUTCD), California Vehicle Code
(CVC), and based on engineering judgement, it was determined that red curb should be installed
at the intersection of Delta Avenue and Mission Drive as well as upgrading the striping of the
existing crosswalks.
DISCUSSION
During the February 3, 2022, Traffic Commission Meeting, staff provided a presentation regarding
the existing roadway conditions at the intersection of Mission Drive and Delta Avenue. The traffic
review included an analysis of the existing roadway conditions, 5.5 -years of available collision
data and a line -of -sight analysis.
Staff obtained collision data from the computerized collision records system maintained by the
State of California called the Statewide Integrated Traffic Records Systems (SWITRS). An
analysis was conducted of available collisions that were reported to SWITRS and that occurred
within 250 -feet of the subject intersection of Mission Drive and Delta Avenue.
The collision analysis was conducted over approximately a 5.5 -year period between January 2016
through October 2021 (available data at the time of traffic review). Per the Collision History
Analysis, there were a total of nine collisions within 250 -feet of the intersection at Delta Avenue
and Mission Drive over the last 5.5 years. Out of the nine collisions, four were broadside collisions
and five were rear end collisions.
A line -of -sight analysis was conducted to determine the stopping sight distance for vehicles to
clearly see oncoming traffic to safely proceed onto the roadway and to determine how much red
curb should be installed.
A detailed traffic report and proposed recommendations diagram are included in the Technical
Report within Attachment A; please refer to Figure 8 in Attachment A for the proposed
recommendations diagram.
STAFF RECOMMENDATION
The Traffic Commission voted 5-0 to approve the staff recommended measures at the intersection
of Mission Drive and Delta Avenue. It is recommended that the City Council authorize approval
for the following improvements at the intersection of Mission Drive and Delta Avenue:
1. Install yellow ladder striping for the existing crosswalks at Mission Drive and Delta
Avenue in the west and north legs.

2. Install approximately 40 -feet of red curb along the north side of Mission Drive. This red
curb is recommended to provide a clear line of sight for any waiting pedestrians. The red
curb should be installed between the curb return to the yield line.
3. Install approximately 20 -feet of additional red curb along the south side of Mission
Drive. This red curb is recommended to provide a clear line of sight for any waiting
pedestrians. The existing red curb should be extended up to the driveway.

SUMMARY
On behalf of the City of Rosemead, engineering staff completed a traffic review and recommended
appropriate measures at the intersection of Mission Drive and Delta Avenue.
The City of Rosemead received a resident request to review the line of sight and existing conditions
at the intersection of Mission Drive and Delta Avenue. In response to this request and on behalf
of the City, engineering staff completed a traffic review and recommended appropriate curb
markings and traffic measures along Mission Drive to increase visibility for drivers turning left
onto Mission Drive from Delta Avenue. The resident reported that citizens making a left-hand turn
from Delta Avenue onto Mission Drive have an obstructed view due to parked vehicles along
Mission Drive. The installation of red curb along Mission Drive would improve overall visibility
for drivers at the intersection.
ANALYSIS
The traffic review included an analysis of the existing roadway conditions, 5.5 -years of available
collision data and a line -of -sight analysis.
Mission Drive: In the City of Rosemead, Mission Drive is an east/west minor arterial roadway and
is 64' (feet) wide. Mission Drive has a posted speed limit of 40 MPH and has two lanes in each
direction divided by a solid double yellow centerline. Parking is allowed along the north and south
side of Mission Drive except in areas marked by red curb and on street sweeping days. Land use
along this segment of Delta Avenue is a mixture of Single Family Residential, Open Space, and
Planned Development. The west leg of the intersection of Mission Drive at Delta Avenue consists
of an uncontrolled regular striped crosswalk outlined with in -road lights and a solar powered

Page 2 of 3
Pedestrian Crossing Assembly (SW24-2) with Flashing lights, which appear to not be functioning
properly based on a field review. Public Works is aware and working to address the functionality
of the equipment. The curb along the north and south side of Mission Drive also consists of marked
red curb as shown on Figure 2. As motorists approach Delta Avenue, Mission Drive consists of
solid white side striping along the north and south sides of Mission Drive to prevent vehicles from
parking too close to the corner as EB & WB motorists turn left and right onto Delta Avenue from
Mission Drive.
Delta Avenue: In the City of Rosemead, Delta Avenue is a north/south local roadway with a Prima
Facie speed limit of 25 MPH and is 40' (feet) wide with one lane in each direction and no marked
centerline south of Mission Drive. Delta Avenue, north of Mission Drive also has one lane in each
direction with approximately 50' (feet) of double yellow centerline located at the intersection with
Mission Drive. Parking is allowed along the east and west side of Delta Avenue except in areas
marked by red curb and on street sweeping days. Land use along this segment of Delta Avenue is
a mixture of Single Family Residential, Open Space, and Planned Development.
A Collision History Analysis 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 (S WITRS). An analysis was conducted of available
collisions that were reported to SWITRS and that occurred within 250 -feet of the subject
intersection of Mission Drive and Delta Avenue.
The collision analysis was conducted over approximately a 5.5 -year period between January 2016
through October 2021 (available data at the time of traffic review). Per the Collision History
Analysis, there were a total of nine collisions within 250 -feet of the intersection at Delta Avenue
and Mission Drive over the last 5.5 years. Out of the 9 collisions, 4 were broadside collisions and
5 were rear end collisions. A broadside collision back in 2017 occurred when a SB vehicle driving
on the wrong side of the road collided with an EB bicyclist and resulted as other visible injury.
A line -of -sight analysis was conducted to determine the stopping sight distance for vehicles to
clearly see oncoming traffic to safely proceed onto the roadway and to determine how much red
curb should be installed.
STAFF RECOMMENDATION
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 red curb should be installed

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 collisions (Maze and Plazak 2000). These
unobstructed views form triangular areas known as sight

Any object within the sight triangle that would obstruct the driver's view of an approaching vehicle should
be removed or modified or appropriate traffic control measures should be installed as per the Manual on
Uniform Traffic Control Devices (CAMUTCD). 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, so it is necessary to consider the width of a vehicle when determining
the amount of red curb needed to obtain a clear sight triangle.

Per A Policy on Geometric Design of Highways and Streets (AASHTO) Table 3-1, for a roadway with a
posted speed of 40 MPH the clear sight distance needed is 305 feet. Table 2 below summarizes the
Stopping Sight Distance based on design speeds and Figure 4 above presents an example of a clear sight
triangle at an intersection. Figure 5 below shows an Example of Stopping Sight Distance Triangle with
Vehicles Parked Along Curb and Figure 6 and Figure 7 shows the calculated amount of clear sight that is

and reiterated that bicyclist should not be on the sidewalk, She also mentioned of a broken sewer
lid in that area and a raised bolt on the yellow section of the ADA curb ramp that needs to be fixed,

ADA compliant.
