A field investigation was conducted on June 12, 2024, which included site observations at the
intersection of Grand Avenue and Muscatel Avenue. It was observed that the existing stop signs, and
parking signs were in good condition, as well as the red curb installed along the south side of Grand
Avenue. The shoulder stripping located along Grand Avenue, east and west of Muscatel Avenue, was
observed to be faded. The available line of sight was found to be insufficient, for vehicles turning onto
Grand Avenue, due to the geometrical configuration of the intersection.

LINE OF SIGHT ANALYSIS
Sign and pavement markings conditions along the
north side of Grand Avenue, east of Muscatel
Avenue.
A Line -of -Sight analysis consists of reviewing the existing conditions a driver encounters when
approaching an intersection to turn onto the other street and determining if there is limited view for the
driver turning. 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 obstructions. Any
object within the sight triangle that would obstruct the driver's view of an approaching vehicle should be
removed or modified per the Manual on Uniform Traffic Control Device. 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 line of sight. On intersections
in urban areas where street parking is allowed, the common practice by motorists after stopping at the
curb and watching and yielding for any potential pedestrians crossing on the sidewalk, is to pull a sufficient
distance forward in the parking lane to have a better view of oncoming traffic. Figure 6 presents an
example of a clear sight triangle at an intersection.

TRAFFIC REVIEW OF THE INTERSECTION OF GRAND AVENUE AND MUSCATEL AVENUE
ALL -WAY STOP CONTROL CRITERIA FOR DETERMINING IF STOP CONTROL IS WARRANTED
Traffic control devices work in concert with the basic "rules of the road" contained in traffic laws and
ordinances. The California Manual of Uniform Traffic Devices (CAMUTCD) describes applications,
warrants, and placement of STOP signs (R1-1). The STOP sign is a regulatory device that is used when
traffic is required to stop. STOP signs are used to assign right-of-way at an intersection. Multi -way control
is used where the volume of traffic on the intersecting roads is approximately equal. Stop signs are not
used as a speed control device. Since a STOP sign causes inconvenience to motorists, it should be used
only where warranted. There are several factors that an intersection needs to meet for the consideration
of all -way stop control; criteria include minimum volumes on each of the street approaches, collision
investigation, speed of traffic, number of pedestrians and potential sight obstructions.
All -Way Stop Installation
The following briefly outlines the Criteria for the installation of All -Way stop warrants.
The placement of All -Way stop control is warranted when' minimum volume thresholds are exceeded:
A. Traffic control signals are justified.
B. A crash problem exists as indicated by 5 or more collisions in a 12 -month Period.
C. Minimum Volumes are met if:
1. Volume entering intersection from the major approach (total of both approaches) averages
300 vehicles Per hour for any 8 hours of an average day. And
2. The combined vehicle, pedestrian and bicycle volumes entering the intersection from the
minor street approaches averages at least 200 units per hourforthe same 8 hours.
3. If the 851' percentile approach speed of the major street exceeds 40 mph the minimum
volumes are 70 percent of the above values.
Peak hours used in Table 5 are from ADT counts taken on each approach on Grand Avenue and Muscatel
Avenue to determine if the intersection met volume warrants for all -way stop installation.
The following Table 5 summarizes traffic during the highest 8 peak hours of the day on both streets.

As seen in Table 5, the intersection of Grand Avenue and Muscatel Avenue does not exceed minimum
volume warrants for none of the streets. The vehicular volume along Muscatel Avenue is significantly
low. Additionally, after reviewing the available collision data, in the past three years there has only been
two collisions repoted, which does not meet miminum volumes required. For these reasons, the
intersections does not meet warrants for the installation of an All -Way Stop control at this time.
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, the intersection of Grand Avenue and Muscatel Avenue does not meet the warrants required
for the installation of an all -way stop. There was not enough vehicular traffic traveling through the area,
as well as a low number of collisions over the last 3 -year period. However, it was determined that the
intersection of Grand Avenue and Muscatel Avenue would benefit from the installation of additional
traffic devices. The following measures are recommended and shown in the Recommendation Exhibit
below:

ft of red curb adjacent to the fire hydrant, for a total of 30 -ft of red curb.
b. It is important to note that parking is allowed along Grand Avenue east of the location
where red curb would be installed. Installing red curb along this stretch of curb will not
affect parking for residents living in the area, as there is plenty of parking east and south
of the intersection.
2. INSTALL RED CURB: Install 30 -ft of red curb at the southwest corner of the intersection at
Muscatel Avenue and Grand Avenue.
a. Install 30 -ft of red curb along the south side of Grand Avenue, at the intersection with
Muscatel Avenue.
b. It is important to note that parking is allowed along Grand Avenue west of the location
where red curb would be installed. Installing red curb along this stretch of curb will not
affect parking for residents living in the area, as there is plenty of parking west and south
of the intersection.
3. REFRESH WHITE SIDE STRIPING MARKINGS: Refresh faded white side striping markings that were
installed along Grand Avenue, on the east side and west side of the intersection with Muscatel
Avenue.
a. The white side striping with diagonals is faded, and needs to be refreshed to improve
visibility in the area. It will also alertvehicles that those areas are not allowed to be parked
on, ensuring line -of -sight for vehicles turning onto Grand Avenue from Muscatel Avenue.
4. INSTALL "CROSS TRAFFIC DOES NOT STOP" PLAQUE (W4 — 4P): Install "Cross Traffic Does Not
Stop" plaque (W4 — 4P) on the Stop sign signpost that is located along Muscatel Avenue, at the
intersection with Grand Avenue.
S. REPLACE MISSING SPEED LIMIT SIGN (112 —1): Replace missing "30" MPH Speed Limit Sign that
was located on the west side of Muscatel Avenue, approximately 110 -ft south of Grand Avenue.
a. Speed Limit Sign should be installed adjacent to the existing 30 MPH pavement legend
along Muscatel Avenue for southbound traffic.

Minutes of the Special
ROSEMEAD TRAFFIC COMMISSION MEETING
August 1, 2024
The special meeting of the Rosemead Traffic Commission was called to order by Chair Orange at 7:03 p.m,
in the Council Chambers, 8838 E. Valley Boulevard, Rosemead, California,
FLAG SALUTE: Commissioner Hermosillo
INVOCATION: Vice Chair Lang
PRESENT: Commissioner Chang, Commissioner Hermosillo, and Vice -Chair Lang
ABSENT: Commissioner Nguyen, Chair Drange
STAFF PRESENT: Director of Public Works Wang and Commission Liaison Nguyen

A. ALL WAY STOP REQUEST AT GRAND AVENUE AND MUSCATEL AVENUE
Associate Engineer Richter explained that the City received a resident request to evaluate the intersection
of Grand Avenue and Muscatel Avenue and determine if the intersection qualifies for the installation of an
all -way stop. The resident expressed concern for vehicles speeding through the area along Grand Avenue
and has requested that an all -way stop or other traffic calming measures be installed at this location. In
response to this request and on behalf of the City, engineering staff completed a traffic review to determine
if an all -way stop was warranted to be installed at the intersection of Grand Avenue and Muscatel Avenue,
and recommended appropriate measures.
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 Grand Avenue and Muscatel Avenue does not meet
the requirements for the installation of an all -way stop. However, it was determined that this area along
Grand Avenue and Muscatel Avenue would benefit from the installation of other traffic calming measures.
Commissioner Hermosillo asked by how much this location failed to meet the all -way stop warrant.
Associate Engineer Richter replied it was a significant amount on the minor street. Collision data in the last
three years, as well as the last twelve months is also considered and there was none based off of the
review.
Vice Chair Lang opened the public comment period.
The City received a public comment via Zoom from Donna Chow commenting that the proposed
recommendations to install a cross traffic does not stop sign on the existing stop sign and additional red

curb at the southeast comer of Grand Avenue and Muscatel Avenue would not help with the line of sight
issue due to parked cars and speeding vehicles.
Vice Chair Lang closed the public comment period.
Commissioner Hermosillo commented Grand Avenue does have a bend at the intersection, which would
add to the light of sight issue. He proposed to extend the red curb.
Commissioner Chang commented that there is existing a white hatched zone where cars are not allowed to
park. He added that if speeding is the main issue, then installing additional red curb may not be enough to
help.
Vice Chair Lang asked if there are any additional recommendations to address the line of sight issue.
Associate Engineer Richter replied the red curb is intended to remind drivers to not park in the white hash
zone. She explained further on the line -of -sight analysis at this location and why it was recommended to
install additional red curb and refresh the white hatched lines. For the speeding concern in the area, a traffic
calming review may be conducted in the future, but these are the proposed recommendations specific to the
stop sign request.
Commissioner Chang asked if we could consider installing a stop sign within the white hatched area.
Associate Engineer Richter replied that a stop sign cannot be placed in an area where the vehicle counts do
not meet the requirements.
Commissioner Chang asked if plastic bollards could be installed as delineators in the hatched area as a way
to slow down vehicles.
Associate Engineer Richter replied that is an option we can consider to help vehicles traveling eastbound
see the oncoming intersection and hopefully slow down.
Vice Chair Lang asked if a dome mirror could be proposed.
Associate Engineer Richter replied she does not believe a dome mirror would work in this situation because
the north part of the intersection there is a driveway onto private property that we do not want to encroach.
The delineators would be the best solution to help eastbound vehicles approaching the intersection.
Commissioner Chang asked If a warning sign on Grand Avenue could be warranted due to the curve of the
street along Grand Avenue.
Associate Engineer Richter replied we could place a curve warning sign and mentioned for reference that
there will be a traffic calming study along this street segment as well.
Commissioner Chang asked if it was noticed if there was significant fading or skid marks in the hatched
striping during the field observations.
Associate Engineer Richter replied it did look faded, which is why one of the proposed recommendations is
to refresh the area.

Commissioner Chang commented that appears to be an indicator of people ignoring the white striping and
that refreshing may be a costly and ineffective measure.
Commissioner Chang made a motion, seconded by Commissioner Hermosillo, to approve staff
recommendations, and amend to include installation of a curve road warning sign and flexible
delineators on both southside corners on Grand Avenue. Vote resulted in:
Yes: Chang, Hermosillo, Lang
