SUBJECT: ALL WAY STOP REQUEST AT ENCINITA AVENUE AND PITKIN STREET
SUMMARY
On behalf of the City of Rosemead, engineering staff has completed an all-way stop and line-of-
sight review, as well as recommended appropriate improvements at the location of Encinita
Avenue and Pitkin Street.
The City of Rosemead received a resident request regarding the installation of an all-way stop at
the intersection of Encinita Avenue and Pitkin Street. The resident expressed concerns for
pedestrians crossing the existing uncontrolled crosswalk on the north leg of Encinita Avenue at
Pitkin Street, and stated that there is not enough visibility for vehicles and pedestrians in the area.
The resident also expressed concern regarding the flashing pedestrian crossing signage, and stated
that not all of the lights are functioning at the intersection. The resident also stated that at night it
is difficult to see in this area along Encinita Avenue, and expressed that residents feel unsafe to
cross due to the lights not functioning at the crosswalk. 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 Encinita Avenue and Pitkin Street, and
recommended appropriate measures.
ANALYSIS
The traffic review included an analysis of existing conditions, 3-years of available collision data,
Average Daily Traffic (ADT) counts, 24-hour speed survey counts, peak hour turning movement
counts (TMC), peak hour pedestrian movement counts, and a field review at the intersection of
Encinita Avenue and Pitkin Street.

Existing Conditions:
Encinita Avenue runs north and south and is considered a major collector road. Encinita Avenue
has a speed limit of 30 MPH, and a marked school speed limit of 25 MPH. Encinita Avenue is
approximately 36-feet wide north of the intersection with Pitkin Street, with one lane in each
direction and is marked with a dashed yellow centerline. Encinita Avenue is approximately 42-
feet wide south of the intersection with Pitkin Street, with one lane in each direction and a dashed
yellow centerline. Parking is available on the east and west side of Encinita Avenue, except where
the curb is marked red. This segment of Encinita Avenue is adjacent to single-family residential
homes located on the east side of the street, and parallels Encinita Elementary School, which is
located on the west side of the street. There is an existing uncontrolled pedestrian crosswalk at the
intersection with Encinita Avenue and Pitkin Street at the south leg and east leg of the intersection,
and a crossing guard who is stationed at this intersection for morning school drop off and afternoon
school pick up.
Pitkin Street runs east and west and is considered to be a local road by the California Road
Functional Classification. Pitkin Street has a prima facie speed limit of 25 MPH. Pitkin Street is
approximately 40-feet wide, with one lane of travel in each direction and no marked centerline.
Parking along the north and south side of Pitkin Street is permitted where the curbs are not marked
red. This segment of Pitkin Street runs along single-family residential homes on both sides of the
street, and dead ends at the intersection with Encinita Avenue, adjacent to Encinita Elementary
School.
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 the intersection of Encinita
Avenue and Pitkin Street does not meet the requirements 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 this area along Encinita
Avenue and Pitkin Street would benefit from the installation of other traffic calming measures.
Please refer to the Installation Exhibit in Attachment A for a conceptual exhibit
representation of the proposed recommendations.
These improvements include:

FIELD INVESTIGATION
A field investigation was conducted on Tuesday, March 25, 2025, which included site observations at the
intersection of Encinita Avenue and Pitkin Street. It was observed that the flashing pedestrian crossing
signage and in-road lights at the south leg of the intersection are not functioning properly. Most of the
in-road lights do not work, and the ones that light up are very faint. The lights in the pedestrian crossing
signage are also faded, and difficult to see. There is a crossing guard posted at the southeast corner of
the intersection of Encinita Avenue and Pitkin Street, who assists pedestrians crossing the south leg and
east leg of the intersection. The crossing guard used the pedestrian push button when crossing the
crosswalk, and vehicles traveling along Encinita Avenue stopped for the crossing guard. Due to the
signalized intersection approximately 300-feet north of Pitkin Street, there was a backup of vehicles on
Encinita Avenue as well as on Lower Azusa Road during both the morning drop off and afternoon pickup.
Northbound vehicles traveling along Encinita Avenue would back up approaching Lower Azusa Road,
and vehicles would often queue into the middle of the intersection with Pitkin Street.
During the field review in the morning, it was observed that the drop-off time between 7:30 – 8:30 AM
has the most vehicular and pedestrian traffic. Vehicles frequently parked in designated "No Parking"
zones, contributing to congestion and reducing visibility for both drivers and pedestrians. Some drivers
stopped in the middle of the roadway to drop off students, prompting children to cross Encinita Avenue
in the middle of the segment. It was also observed that some vehicles completed U-turns and sudden
lane changes in the middle of the street, causing additional congestion due to drivers attempting to
navigate the traffic. This issue did not occur in the afternoon based on the observations that were
completed. The majority of the traffic issues in this area occurred in the morning.
The speed feedback sign on the north leg of the intersection is non-functional and fails to flash,
rendering it ineffective in alerting drivers to their speed traveling southbound within the school zone.
This sign needs to be replaced, to better alert drivers of their travel speed in front of Encinita
Elementary School. It was also observed that the rumble dots along Encinita Avenue for both
northbound and southbound traffic had some dots missing and should be replaced. These rumble dots
help alert drivers to travel slower in the area, as well as bring awareness to their surroundings along the
street segment. Due to the number of student age pedestrians in this area, it is important that drivers
travel along Encinita Avenue with additional caution.

LINE OF SIGHT ANALYSIS
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 7 presents an
example of a clear sight triangle at an intersection.

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 2 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 hour for the same 8 hours.
3. If the 85th 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 6 summarizes traffic during the highest 8 peak hours of the day on both streets.

As seen in Table 5, the intersection of Encinita Avenue and Pitkin Street does not exceed minimum
volume warrants for none of the streets. The vehicular volume along Pitkin Street is significantly low.
Additionally, after reviewing the available collision data, in the past three years there has only been one
collision reported, which does not meet miminum volumes required. For these reasons, the intersection
does not meet warrants for the installation of an All-Way Stop control at this time for Encinita Avenue
and Pitkin 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, the intersection of Encinita Avenue and Pitkin Street 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 Encinita Avenue and Pitkin Street would benefit from the installation of additional traffic
devices. The following measures are recommended and shown in the Recommendation Exhibit below:
Recommendations:
1. INSTALL 20-FT OF RED CURB: Install 20-ft of red curb at the northeast corner of the intersection
at Encinita Avenue and Pitkin Street, on the east side of the street along Encinita Avenue.
a. Install 20-ft of red curb at the northeast corner of Encinita Avenue and Pitkin Street, along
the east side of Encinita Avenue.
b. It is important to note that parking is allowed along Encinita Avenue north 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 north and east
of the intersection.
2. REMOVE AND REPLACE NON-FUNCTIONING FLASHING PED CROSSING SIGNAGE WITH NEW
DOUBLE SIDED SCHOOL CROSSING SIGNAGE (S1-1 & W16-7P) WITH RRFBS AND PED CROSSING
PUSH BUTTONS (R23E (CA)): Remove and replace the non-functioning Flashing Pedestrian
Crossing Signage with new Retroreflective Double Sided Pedestrian Crossing Signage with RRFBs
(S1-1 & W16-7P) at the intersection of Encinita Avenue and Pitkin Street on the south leg of the
intersection.
a. Install new pedestrian push buttons with signage (R23E (CA) variation) on existing poles
for new flashing pedestrian crossing signage at the southeast and southwest corners of
the intersection at Encinita Avenue and Pitkin Street.
b. Remove the non-functioning signage and in-road lights system at the intersection along
Encinita Avenue.
3. REFRESH EXISTING CROSSWALKS AT INTERSECTION: Refresh the existing crosswalks on the east
leg and south leg of the intersection at Encinita Avenue and Pitkin Street.
4. REMOVE AND REPLACE NON-FUNCTIONING SPEED FEEDBACK SIGNAGE: Remove and replace
the non-functioning Speed Feedback Signage along Encinita Avenue for southbound traffic
approaching Pitkin Street.

5. REFRESH EXISTING PAVEMENT LEGENDS ALONG ENCINITA AVENUE: Refresh the existing “SLOW
SCHOOL XING” and “KEEP CLEAR” pavement legends along Encinita Avenue approaching and at
the intersection with Pitkin Street.
6. REPLACE MISSING RUMBLE DOTS ALONG ENCINITA AVENUE: Replace the missing rumble dots
along Encinita Avenue for northbound and southbound traffic both north and south of the
intersection with Pitkin Street.
7. REFRESH CENTERLINE ALONG ENCINITA AVENUE: Refresh the pavement centerline along
Encinita Avenue, between Lower Azusa Road and Dell Rio Street.
8. TRIM VEGETATION: Maintain a periodic maintenance of the vegetation along Encinita Avenue
and Pitkin Street to prevent sight obstructions caused by overgrown vegetation.
