STOP SIGN WARRANT STUDY AT THE INTERSECTION OF NEW AVENUE AND GRAVES AVENUE
The City of Monterey Park requested an evaluation of the intersection of New Avenue and Graves Avenue
to see if existing conditions warrant the installation of All -Way Stop control at this intersection. To provide
a complete evaluation, a traffic review included an evaluation of existing roadway conditions, 3 years of
available collision data and completion of Stop Sign Warrants as found in the California Manual on
Uniform Traffic Control Devices (CAMUTCD) Section 26.07. The assessment included the collection of 24-
hour vehicle counts, a 24-hour speed survey on Graves Avenue near New Avenue, an intersection turning
movement count, and a review of line of sight for vehicles exiting New Avenue onto Graves Avenue. The
traffic operations at this intersection were also observed during arrival and pick up times at Monterey
Vista Elementary school.

To determine how many pedestrians are crossing at the intersection of Graves Avenue and New Avenue,
peak hour pedestrian counts were taken during the same count periods as the intersection turning
movement counts on Tuesday, September 20`", 2022. The pedestrian counts tally the number of adult
and school age pedestrians crossing in each leg of the intersection during the count times of 7-9AM, 1-
3PM and 4-6PM. Each hour is shown in Table 1. The west or east leg counts reflect pedestrians crossing
Graves Avenue. Please refer to Attachment 1.2 at the end of the report for the count sheet.

A second pedestrian count was taken on Tuesday, October 18`", 2022, during the school drop off and
pick up time for Monterey Vista Elementary School. The pedestrian counts shown in Table 2 and Table 3
tally the number of adult and school age pedestrians in each leg of the intersection. The pedestrian
counts took place at the beginning of the school day between 7:45 and 8:45AM, and at the end of the
school bell between 2:OOPM and 3:OOPM. The counts were divided into 15 -minute increments in the
tables below (Table 2 and Table 3).

STEVENS AVENUE AT GRAVES AVENUE -PEDESTRIAN COUNT AND OBSERVATIONS
An additional pedestrian count was conducted at the intersection of Stevens Avenue and Graves Avenue,
which is located approximately 359 -feet eastof the intersection of Graves Avenue and New Avenue. There
is a marked crosswalk in the west leg of this intersection. Observations were made to determine the
number of pedestrians crossing the intersection at the marked crosswalk.
These counts were taken on Tuesday, October 18'h, 2022, during the school drop off and pick up time for
Monterey Vista Elementary School. The pedestrian counts shown in Table 4 and Table 5 tally the number
of adult and school age pedestrians in each leg of the intersection. The pedestrian counts took place at
the beginning of the school day between 7:45 and 8:45AM, and at the end of the school bell between
2:OOPM and 3:OOPM. The counts were divided into 15 -minute increments in the tables below (Table 4 and
Table 5). As shown in the tables there were only a few pedestrians that are using this uncontrolled
crossing.

Figure 6: Vehicle Movement Observations during pick up from Monterey Vista Elementary School
On Tuesday, October 18", 2022, student pick-up from Monterey Vista Elementary School was observed
between 2:OOPM-3:OOPM. Prior to the end of the school day at 2:35PM, it was observed that vehicles
parked along both sides of the street on Graves Avenue, as well as on both sides of the street at New
Avenue. Cars parked eastbound and westbound along Graves Avenue had difficulty re-entering traffic
following student pickup in the afternoon, due to the number of vehicles traveling along Graves Avenue
as well as the speed of the drivers traveling eastbound along Graves Avenue. Graves Avenue is on a
downhill slope. It was observed that eastbound vehicles seemed to be traveling faster than westbound
vehicles along Graves Avenue.
Vehicles also parked northbound and southbound along New Avenue north of Graves Avenue for student
pickup. Most of the vehicles parking along New Avenue for pickup parked on the west side of the street
parallel to Monterey Vista Elementary, however some drivers parked on the east side of the street as well.
It was observed during student pickup that several pedestrians, both adult and student age, crossed the
street midblock along New Avenue north of the intersection at Graves Avenue. The midblock crossing of
pedestrians affected the northbound and southbound vehicle traffic along New Avenue, as drivers
traveling along New Avenue were having to break for pedestrians in the area. The midblock crossing was
mostly occurring adjacent to the teacher's parking lot driveway entrance along New Avenue.
Observations were also conducted in the morning and the afternoon on Tuesday, October 18`", 2022, at
the intersection of Stevens Avenue and Graves Avenue. During the morning observations, very few
pedestrians crossed at the intersection of Stevens Avenue and Graves Avenue. Of the pedestrians that
crossed Graves Avenue at the intersection in the morning, most were not dropping off students at
Monterey Vista Elementary School. For the afternoon observations at Stevens Avenue and Graves Avenue,
even less pedestrians were counted than in the morning of the same day. Almost all adults picking up
students crossed midblock to the west of the intersection of Graves Avenue and Stevens Avenue, so there
were very few pedestrians that used the existing crosswalk.

LINE OF SIGHT AT INTERSECTIONS
As part of the review a line -of -sight assessment was prepared for vehicles exiting New Avenue onto Graves
Avenue. The driver of a vehicle approaching or departing from an intersection should have an
unobstructed view of the intersection, including any traffic control devices, and enough clear view along
the intersecting highway to permit the driver to anticipate and avoid potential collisions. These
unobstructed views form triangular areas known as sight triangles. 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 devices should be installed as per A Policy on Geometric Design of Highways
and Streets (AASHTO). 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 if red curb is needed to obtain
a clear sight triangle. Looking at existing sight triangles at the corner it is suggested that 20' of red curb
be painted from the ECR to the driveway apron of the first house on the NE corner on Graves Avenue. The
red curb would improve sight distance for exiting vehicles from New Avenue as well as provide for added
sight distance of crossing pedestrians and provide drive space for a WB right turning vehicle.

SPEED SURVEY
To assess the speed at which vehicles are traveling along Graves Avenue, speed samples were taken. A
24-hour speed sample was taken on Tuesday, September 20`", 2022, on Graves Avenue east of New
Avenue. The 85`" percentile speed of vehicles along Graves Avenue is shown to be at 40 MPH which is
higher than the posted speed limit of 35 mph outside of school hours. During school let out and pick up it
was noted in the speed survey that some vehicles were still traveling above the 25 MPH posted school
speed limit. This suggests that some vehicles are not slowing during the times students are on the

CONCLUSIONS AND RECOMMENDATIONS
As a result of extensive field data collection and review, including reviewing all of the counts, line of sight,
roadway conditions and observations at this location, and engineering judgement, staff has determined
that the intersection of New Avenue and Graves Avenue would benefit from the installation of all -way
STOP control as determined by the guidelines in the California Manual on Uniform Traffic Control Devices
(CAMUTCD) Section 26.07 and the California Vehicle Code (CVC). The installation of all -way -stop control
is recommended based on street conditions, pedestrians crossing midblock as well as the street
grade/slope on Graves Avenue west of New Avenue. In addition to all -way stop, there are several other
improvements that should be implemented. These are listed below and shown in the Installation Exhibit.
After careful consideration a crosswalk was not striped in the WL of the intersection. A marked crosswalk
was not included in the WL due to physical conditions on either curb (electric vault, power cabinet, water
meters on south side and power pole and catch basin along the north curb) these items make it so a
marked crosswalk would not meet ADA requirements for an accessible ramp so is infeasible to install.
However, although no crosswalk is striped pedestrians can legally cross in the west leg per the California
Vehicle Code Section 21950, The driver of a vehicle shall yield the right of way to a pedestrian crossing the
roadway within any marked or unmarked crosswalk at an intersection. There is existing a yellow midblock
crosswalk at Stevens Avenue to the east and at Pomelo Avenue to the west of the intersection.
City of Monterey Nark I Nage 1r of [s
STOP SIGN WARRANT STUDY AT THE INTERSECTION OF NEW AVENUE AND GRAVES AVENUE
Based upon engineering judgment, where the improvement of the
conspicuity of a standard regulatory, warning, or guide sign is desired, any
of the following methods may be used, as appropriate, to enhance the
sign's conspicuity. This includes:
• Adding one or more red or orange flags (cloth or retroreflective
sheeting) above a standard regulatory or warning sign, with the
flags oriented so as to be at 45 degrees to the vertical.
• Or where engineering judgment indicates a need to draw
attention to the sign during nighttime conditions, a strip of
retroreflective material may be used on regulatory and warning
sign supports.
6. Remove One "Left Turn Arrow" and S' of the Center Yellow line for EB Traffic and Install New Stop
Bar and STOP Pavement Legend in both EB Lanes
Removal the easternmost "Left Turn Arrow' located in the EB left turn pocket at Graves Avenue and New
Avenue. Remove about 5' of the yellow center line and then install Stop Bar and STOP Pavement Legend
in both the left turn pocket and the through traffic lane for eastbound traffic on Graves Avenue. The Stop
Bar and STOP legends should be shifted around 5' to the west to be in line with the NW curb face.
7. Install 20' of red curb on the north side of Graves New Avenue (NE Corner)
The red curb will improve sight distance of pedestrians waiting to step off the curb to cross in the NL
crosswalk as well as provide room for a right turn vehicle to make the turn without being stuck behind a
parked car.
8. Install "Stop Ahead" Signage (W3-1) ahead of the intersection at New Avenue and Graves Avenue for
Both EB and WB Directions.
Install "Stop Ahead" Signage (W3-1) ahead of the intersection at New Avenue and Graves Avenue. Install
EB sign approximately 160 -ft west of the intersection and the WB sign approximately 200 -ft east of the
intersection at Graves Avenue and New Avenue. Both new signs require the installation of new signposts,
with the base of the sign at least 7' from the ground.
9. Install New STOP AHEAD Pavement Legends along Graves Avenue.
Install new STOP AHEAD pavement legends adjacent to the STOP AHEAD signs on Graves Avenue for both
directions. Pavement legends will serve to provide an added reminder that Graves Avenue at New will be
STOP controlled.
Recommendations for the intersection of Graves Avenue and New Avenue are shown in the following
Exhibit.
