STAFF REPORT
TO: THE HONORABLE MAYOR AND CITY COUNCIL
FROM: BEN KIM, ACTING CITY MANAGER
--
DATE: APRIL 26, 2022
SUBJECT: APPROVAL OF THE TRAFFIC COMMISSION RECOMMENDATIONS
FOR TRAFFIC IMPROVEMENTS AT THE INTERSECTION OF
MISSION DRIVE AND BARTLETT AVENUE
SUMMARY
At the March 3, 2022, Traffic Commission Meeting, staff presented recommendations to improve
the existing roadway conditions at the intersection of Mission Drive and Bartlett Avenue. After
discussion and presentation of the item, the Traffic Commission approved the staff
recommendations for the area. 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, and staff would utilize the approved the Fiscal Year
2021-2022 Traffic Signs and Markers available funds.
BACKGROUND
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 at the
intersection of Bartlett Avenue (north of Mission Drive) and Mission Drive to increase visibility
for drivers turning from Bartlett Avenue (north of Mission Drive) onto Mission Drive. The
installation of a red curb along the northside of Mission Drive, just east of Bartlett Avenue, would
deter vehicles from parking up to the curb return and provide a clearer line of sight for vehicles
exiting Bartlett Avenue to see oncoming and approaching traffic on Mission Drive at this location.
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 the intersection of Bartlett
Avenue (North of Mission Drive) and Mission Drive would benefit from the installation of red

curb along the northside of Mission Drive, just east of Bartlett Avenue.
DISCUSSION
During the March 3, 2022, Traffic Commission Meeting, staff provided a presentation regarding
the existing roadway conditions at the intersection of Mission Drive and Bartlett Avenue. The
traffic review included an analysis of the existing roadway conditions, a review of approximately
5 -years of available collision data, and a line -of -sight analysis.
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. Mission Drive is posted at 35 mph. Per A Policy on Geometric Design of
Highways and Streets (AASHTO) Table 3-1, for a roadway with a posted speed of 35 MPH the
clear sight distance needed is 250 feet. Based on the line -of -sight analysis, approximately 35 feet
of red curb is recommended to be installed on the north side of Mission Drive, just east of Bartlett
Avenue. The red curb will deter vehicles from parking up to the curb return and provide a clearer
line of sight for vehicles exiting Bartlett Avenue to see oncoming and approaching traffic on
Mission Drive at this location. The red curb installation equates to the removal of approximately
2 parking spaces. There will still be approximately 178 feet of available curb space for vehicles to
park along the north side of Mission Drive between Bartlett Avenue and Dubonnet 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.
Staff performed a collision analysis and obtained collision data 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 5.5 -year
period between January 2016 through December 2021 (available data at the time of traffic review).
Per the Collision History Analysis, there was a total of one (1) collision reported within the 5 -year
period for the intersection at Mission Drive and Bartlett Avenue. This reported collision was a
broadside collision that resulted in property damage only.
A detailed traffic report and proposed figure diagram is attached as the Technical Report within
Attachment A to this staff report; please refer to the proposed diagram (Figure 7 & 8) in the
attachment.

AND BARTLETT AVENUE
SUMMARY
On behalf of the City of Rosemead, engineering staff completed a traffic review and recommended
appropriate curb markings to increase visibility for drivers turning from Bartlett Avenue (north of
Mission Drive) onto Mission Drive.
The City of Rosemead received a resident request to evaluate the line of sight visibility and existing
roadway conditions at the intersection of Bartlett Avenue (north of Mission Drive) and Mission
Drive. In response to this request and on behalf of the City, engineering staff completed a traffic
review and recommended appropriate measures.
ANALYSIS
The traffic review included an analysis of the existing roadway conditions, a review of
approximately 5 -years of available collision data, and a line of sight analysis.
Mission Drive: Within the City of Rosemead, Mission Drive runs east and west and is considered
a minor arterial road by the California Road Functional Classification Map with a posted speed
limit of 35 mph. Mission Drive is approximately 64 feet wide with two lanes in each direction and
a marked double yellow centerline. Parking is allowed on the north and south side of Mission
Drive except in areas marked by red curb and on Tuesdays from 6AM — I OAM to allow for street
sweeping. This segment of Mission Drive travels through Single Family Residential zoning, per
the City of Rosemead Official Zoning Map.
Bartlett Avenue: Within the City of Rosemead, Bartlett Avenue runs north and south and is
considered a local road by the California Road Functional Classification Map with a prima facie

speed limit of 25 mph. Bartlett Avenue is approximately 36 feet wide with one lane of travel in
each direction and no marked center line. Parking is allowed on the east and west side of Bartlett
Avenue except in areas marked by red curb and on Tuesdays from 6AM — l OAM to allow for street
sweeping. Bartlett Avenue is stop controlled at Mission Drive, and the northern and southern
segments are offset at Mission Drive. This segment of Bartlett Avenue travels through Single
Family Residential zoning, per the City of Rosemead Official Zoning Map.
Line Of Sight Analysis: 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. Mission Drive is posted at 35 mph. Per A Policy
on Geometric Design of Highways and Streets (AASHTO) Table 3-1, for a roadway with a posted
speed of 35 MPH the clear sight distance needed is 250 feet. Based on the line of sight analysis,
approximately 35 feet of red curb is recommended to be installed on the north side of Mission

LINE OF SIGHT ANALYSIS
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
LOCAL I
Is,nEET
AREA TO BE CLEAR OF I —
VIEW OBSTRUCTION

\ 10. W EDGE OF PAVEMENT
® (y) STATE HIGHWAY
sight triangles as seen in Figure 3. Any object within the Figure 3: Example of Stopping Sight Distance Triangle
sight triangle that would obstruct the driver's view of an approaching vehicle should be removed or
modified or appropriate traffic control devices should be installed as per the Manual on Uniform Traffic
Control Devices. 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's
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 35 MPH the clear sight distance needed is 250 feet. Table 1 below summarizes the
Stopping Sight Distance based on design speeds and Figure 4 presents an example of a clear sight triangle
at an intersection.

Figure 5: Line of Sight Analysis for Vehicles Turning onto Mission Drive from SB Bartlett Avenue
As shown in Figure 5 above, and based on the line of sight analysis, approximately 35 feet of red curb is
recommended to be installed on the north side of Mission Drive, just east of Bartlett Avenue. The red curb
will deter vehicles from parking up to the curb return and provide a clearer line of sight for vehicles exiting
Bartlett Avenue to see oncoming and approaching traffic on Mission Drive at this location. Mission Drive
is posted at 35 mph. The red curb installation equates to the removal of approximately 2 parking spaces.
There will still be approximately 178 feet of available curb space for vehicles to park along the north side
of Mission Drive between Bartlett Avenue and Dubonnet Avenue.
COLLISION INVESTIGATION
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 (SWITRS). The collision analysis was conducted over approximately a
5.5 -year period between January 2016 through December 2021 (available data at the time of traffic
review). Based on the information provided, a summary breakdown of the number of collisions within the
studied segment are listed below and shown in Table 2.

A. TRAFFIC REVIEW OF LINE OF SIGHT FOR VEHICLES EXITING CUL-DE-SAC
LOCATED ON THE WEST SIDE OF MUSCATEL AVENUE NORTH OF LAWRENCE
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 the installation
of red curb to improve line of sight for vehicles exiting from the cul-de-sac located on the West Side
of Muscatel Avenue North of Lawrence Avenue near the address of 4301 Muscatel Avenue. The
resident reported having difficulty exiting the cul-de-sac onto Muscatel Avenue during peak school
hours due to cars being parking up to the curb return on Muscatel Avenue.
Traffic Engineer Robbins explained as part of the traffic review, engineering staff looked at the
existing roadway conditions and a line -of -sight analysis for vehicles exiting onto Muscatel Avenue.
On behalf of the City of Rosemead, Traffic Engineer Robbins provided recommendations for the
installation of 20' of red curb starting at the end of the curb returns on the west side of Muscatel
Avenue on the north and south corners by the cul-de-sac in order to improve line of sight visibility.
Chair Masuda opened the Public Comment period.
The City received a Public Comment via email from Resident James Bui thanking staff for looking
into this item and for the recommendation of red curb installation. The resident expressed that 20'
of red curb is too much and would result in taking away four parking spaces on the street. The
resident suggested the following: 12' or up to 15' of red curb, 20' of no parking within the school
pick up and drop off time, or 20' of red curb allow and the property owners to park in the cul-de-
sac.
The City received a Public Comment via email from the Chen Residence expressing her concerns
with the line of sight visibility when exiting the cul-de-sac. The resident requested to have the line
of sight defined only to allow two cars parked in a row and away from their mailbox.
The City received a Public Comment via email from Resident Yuen Yu Moy expressing how it is
difficult to safely exit from his driveway and from the street parking along Muscatel Avenue due to
the speeding. The resident suggested a stop sign to be installed on the southeast corner of
Muscatel Avenue and Lawrence Avenue or to allow for the construction of a driveway on their
property so they can exit through Lawrence Avenue.
Chair Masuda closed the Public Comment period.

Minutes of March 3, 2022
Page 2 of 8
Chair Masuda commented that the reason there is no parking within the cul-de-sac is because it is
a fire lane and there are signs posted at the entrance, exit, and sides of the curve.
Vice Chair Quintanilla asked if 20' is standard for red curb.
Director of Public Works Chung asked Traffic Engineer Robbins to confirm if 20' is based on
MUTCD Guidelines.
Traffic Engineer Robbins responded that the recommendation of 20' was based on the California
MUTCD Guidelines and also commented that 20' of red curb would only remove one vehicle
parking space on each side.
Commissioner Drange asked if the houses have driveways since they are not allowed to park in
the street.
Director of Public Works Chung responded that each house has a driveway.
A resident who did not identify themselves attempted to make a Public Comment via Zoom,
however, we were unable to receive the comment due to technical issues on the user's end,
Chair Masuda commented he would like to hear the resident's comment regarding the agenda item
before voting on a decision.
Commissioner Liaison Nguyen asked the resident for their contact information, however, did not
receive a response.
Chair Masuda suggested to table the agenda item.
Commissioner Drange asked if we could table the item for the end of the agenda and see if we
could obtain the resident's information before adjourning.

B. TRAFFIC REVIEW FOR RED CURB REQUEST FOR 3247 JACKSON 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 City received a "General Curb Marking Request" from a
resident to evaluate the installation of red curb on either side of the driveway at the address of
3247 Jackson Avenue. The resident requested for the City to install driveway red tipping. In
response to this request and on behalf of the City, engineering staff completed a traffic review and
recommended appropriate measures.
Traffic Engineer Robbins explained as part of the traffic review, engineering staff looked at the
existing roadway conditions as well as an examination of guidelines within the CAMUTCD, CVC,
and City of Rosemead's curb marking policy.
On behalf of the City of Rosemead, Traffic Engineer Robbins provided recommendations for the
installation of red curb on either side of the driveway, often referred to as red tipping in front of the
address of 3247 Jackson Avenue. The recommended 1 foot of red curb will not affect the parking
that is allowed on Jackson Avenue.
Chair Masuda opened the Public Comment period.
There were no Public Comments from the audience.
Chair Masuda closed the Public Comment period.
Vice Chair Quintanilla asked how common is the driveway red tipping in the City.
Traffic Engineer Robbins responded there are quite a few, but mostly seen on the narrower streets.
Vice Chair Quintanilla asked if these requests are received on a conditional basis.
Traffic Engineer Robbins responded if it looks like their driveway is narrow and meets the City of
Rosemead curb marking policy and procedures.
Director of Public Works Chung commented that parked cars were encroaching into their driveway
and making it difficult for the homeowners to safely enter and exit.
Vice Chair Quintanilla asked if a resident presented a narrow driveway and a narrow street, would
we approve their request for red curb also.
Director of Public Works Chung replied that staff would evaluate the request and provide
recommendations to the Traffic Commission for approval.
Chair Masuda commented that the request would be received on a case by case basis.

C. LINE OF SIGHT REVIEW AT THE INTERSECTION OF MISSION DRIVE AND BARTLETT
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 the line of sight
visibility and existing roadway conditions are the intersection of Bartlett Avenue (north of Mission
Drive) and Mission Drive.
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, and a
line of sight analysis.
On behalf of the City of Rosemead, Traffic Engineer Robbins provided recommendations for the
installation of approximately 35' of red curb on the north side of Mission Drive, east of Bartlett
Avenue,

The City received a Public Comment via email from Resident Donna stating it is difficult to see
oncoming westbound traffic when turning on to Mission Drive from Bartlett Avenue due to cars
parking too close to the corner at the northeast corner of Mission Drive and Bartlett Avenue.
The City received a Public Comment from Resident Ryan C. expressing safety concerns when
turning on to Mission Drive from Bartlett Avenue on the south side of Mission Drive due to parked
cars blocking line of sight. The resident suggested extending the existing red curb.
Chair Masuda closed the Public Comment period.
Commissioner Drange commented that several of the Public Comments received were regarding
Bartlett Avenue on the south side of Mission Drive, which is not specific to the agenda item.
Commissioner Drange asked if the residents would need to submit a request for the City to look
into this side of the street or if the City would automatically look into it.
Director of Public Works Chung responded the Traffic Commission could direct staff to look into it.
Chair Masuda confirmed to have staff look into the request regarding extending the red curbing at
the intersection of Mission Drive and Bartlett Avenue, on the south side of Mission Drive.
Director of Public Works Chung asked Traffic Engineer Robbins if the existing red curb on the
south side of Mission Drive meets the requirements of the stopping sight distance.
Traffic Engineer Robbins replied that the red curb on the south side met the MUTCD guidelines. In
order to extend the red curb, staff would need to do a traffic review similar to the other side.
Commissioner Drange commented that since Mission Drive is diagonal, it would seem like
additional red curb would be needed to get the same line of sight as a perpendicular road.
Director of Public Works Chung agreed with Commissioner Drange that the angle of the road is
what is compounding a lot of these line of sight issues. Director of Public Works Chung
recommended to evaluate requests as they are received or to evaluate the entire roadway on
Mission Drive.
Director of Public Works Chung asked the Traffic Commission if they would like to have the
evaluation of Mission Drive as a topic of discussion for a future meeting.
Chair Masuda confirmed they would like to have staff first look into the south side of Bartlett
Avenue and then we can bring back for discussion the option of evaluating the entire roadway on
Mission Drive.
Traffic Engineer Robbins commented that parking spaces will be removed as a result of line of
sight analysis and is something the Traffic Commission would need to consider if evaluating the
entire roadway on Mission Drive.

Director of Public Works Chung agreed with Traffic Engineer Robbin's comment regarding less
parking spaces due to installing red curb.
Resident Ken made a public comment expressing safety concerns when turning left onto Mission
Drive from Bartlett Avenue on the south side of Mission Drive and that safety is more important
than parking spaces.
Chair Masuda asked the Commissioners if there are any questions or comments regarding the
agenda item.
Commissioner Escobar commented that it is evident based on the Public Comment received from
Resident Donna that there is a line of sight issue for turning left onto Mission Drive coming from the
north side of Bartlett Avenue and agrees with staff recommendation.
Vice Chair Quintanilla commented why we would not also look into the parallel streets such as
Dubonnet Avenue on the north side since it also has the same issue with the angle of the road.
Director of Public Works Chung responded staff will take a look at the entire stretch and see if it is
feasible.
Chair Masuda commented it is good to be proactive but that not all streets along Mission Drive may
have a line of sight issue.
Vice Chair Quintanilla agreed with Chair Masuda and commented evaluating from Rosemead
Boulevard up to at least Muscatel Avenue or even up to the City limit as the entire road is at an
angle.
Resident Ernesto Rios made a Public Comment asking if they will receive a letter or email
notification regarding their non -agenda item submitted via email and when it will be addressed.
Director of Public Works Chung confirmed the Public Comment was received and staff can follow
up to provide more information and steps moving forward if the request warrants being brought to
Traffic Commission.
Commissioner Escobar made a motion, seconded by Commissioner Drange, to accept Staff
recommendations. Vote resulted in:
Yes: Masuda, Quintanilla, Drange, Escobar
No: None
Abstain: None
Absent: Nguyen
