B. MONTHLY UPDATES OF VARIOUS PROJECTS/PROGRAMS:
1. ADAPTIVE TRAFFIC CONTROL SYSTEM (ATCS) – AE/Malpica Staff
continues to monitor the system's performance after receiving the updated
software and database upgrades early this summer.
2. STREET REHABILITATION PROJECTS – AE/Malpica – Area 1
Residential and Collector Streets/Golden Springs Drive from Brea Canyon
Road to Lemon Avenue. As of August 31, 2022, the residential slurry and
cape seal, as well as upgraded concrete ADA curb ramps have been partially
completed. The entire parking lot in front of the YMCA was slurry sealed as
part of the contractor's arrangement for using the parking lot as their staging
area. The YMCA staff and parents will be accessing the facility from their
parking lot on the side of the building while the slurry seal dries. Due to some
material shortages and delayed delivery caused by sup ply chain constraints,
the overall Project schedule was extended to the end of September 2022. Area
1 Residential Slurry Seal is completed, and striping is currently scheduled for
the week of September 12, 2022. The concrete demolition work of curb and
gutters, sidewalks, and a few ramp modifications along Golden Springs Drive
between Brea Canyon Road and Lemon Avenue started on Monday, August
29, 2022. The contractor is set to begin the cold mill grinding of asphalt on
Thursday, September 8th, with paving to take place from Monday, September
12th thru Wednesday, September 14th. Final striping is scheduled to begin
during the week of September 12th, followed by loop detector replacements.
Staff is working closely with the contractor to minimize any impacts on the
streets and/or to other projects within the vicinities of the project areas.
3. CALTRANS PAVEMENT REHABILITATION PROJECT/STATE ROUTE
57 FREEWAY – AE/Malpica - Caltrans will issue the upcoming weekend

closure public notification for September 9th through September 12th due to the
hot weather. The weekend closure is part of the SR-57 Rehabilitation Project.
The public will be notified when the next closure is scheduled.
4. GRAND AVENUE/GOLDEN SPRINGS DRIVE INTERSECTION
IMPROVEMENTS – AE/Malpica – As of September 1, 2022, the Project
continues as scheduled. The contractor completed over 270 feet of pipe
jacking thru the east and west golf course slopes. The contractor will continue
work behind the k-rails for the next couple of weeks, after which they will
commence work on the pre-cast architectural feature lighting and additional
concrete work at the intersection.
5. KIOWA CREST PROTECTIVE LEFT TURN WARRANT STUDY –
AE/Malpica – Today, the consultant provided staff with the traffic signal warrant
study, which staff will be reviewing, along with proposed recommendations for
which staff will provide an update at the next Commission meeting.
6.. “NO U-TURN SIGN” ASSESSMENT AT DIAMOND BAR BOULEVARD
AND PALOMINO DRIVE – AE/Malpica - Earlier this summer, staff received a
request for a "No U-Turn" sign at the intersection of Diamond Bar Boulevard
and Palomino Drive to discourage drivers from using this intersection to avoid
the long wait on the southbound left turn pocket at the SR-60 on and off ramp
traffic signal. The City's traffic consultant conducted an assessment and
recommended the City avoid posting a "No U-Turn" sign at this intersection
because the sign would potentially shift the problem to the Palomino Drive
neighborhood. This may force vehicles to turn left onto Palomino Drive and cut
through the gas station in order to get back onto the Diamond Bar Boulevard
SR-60 east on ramp. Staff decided to report this situation to Caltrans to
address this traffic concern with the following recommendations: To extend the
left-turn pocket to accommodate the capacity of traffic; or to increase the green
signal time at the SR-60 eastbound on/off ramps. However, as the SR-57/60
Confluence Project moves forward, a dual left-turn is being proposed at the
Diamond Bar Blvd and SR 60 East on-ramp.
7. SCHOOL SPEED LIMIT SIGN NEAR DIAMOND RANCH HIGH
SCHOOL - ET/Delgado - The City of Pomona conducted a sign assessment
along the southbound direction of Phillips Ranch Road, approaching Scenic
Ridge Drive/Diamond Ranch Road. This assessment was conducted to
establish a school zone within the City of Pomona's boundary limits. Based on
their assessment, Pomona requested staff to consider the installation of school
signage along northbound Chino Hills Parkway, as well as establish a school
zone within City of Diamond Bar’s jurisdiction. Staff worked with one of the
City's on-call traffic consultants to identify the appropriate spacing and location
of the requested signs. The City’s traffic consultant recommended the
installation of two school signs, which were installed in late August 2022. By
establishing this as a registered school zone, and installing signs in Diamond
Bar, it allows for Pomona police to have more enforcement authority for
Diamond Ranch High School traffic.

8. HAWKWOOD ROAD NEIGHBORHOOD TRAFFIC MANAGEMENT
PROGRAM - ET/Delgado. A second neighborhood meeting was held on July
14, 2022, as a part of the regular Traffic and Transportation Commission
meeting. During this second meeting, staff presented the neighborhood with
traffic calming alternatives. A total of 86 households were invited to attend the
hybrid meeting, four (4) of which participated by providing their feedback and
traffic concerns to the Commission. Based on the traffics data, street
geometrics, and resident feedback, staff has prepared a final construction plan
to send back to the residents for an online survey. If the plans are approved
with a 67% majority vote, staff will proceed with the installation of the traffic
calming measures in this neighborhood.
9. NTMP/DEL SOL LANE NEIGHBORHOOD – ET/Delgado - The Public
Works Director/City Engineer has formally approved the final c onstruction
plans administratively without going to the City Council. Upon approval,
construction bids were procured, and staff completed the final administrative
items in order to award a construction contract to the apparent low bidder. The
tentative schedule is to begin construction in October and complete
construction by November.
10. DIAMOND BAR BOULEVARD COMPLETE STREETS PROJECT-
ET/Delgado - The project plans and specifications were completed in 2020,
and the current construction cost is estimated to be between $6-7 million. To
date, the City has secured only $3 million in Metro grant funding for
construction. In mid-June, the City applied for an additional $3.9 million of
Cycle 6 Active Transportation Program (ATP) grant funds, a program funded
by the State and managed by Caltrans. The ATP grant is a competitive
program that funds active transportation projects throughout the State. The
City was selected by Metro to receive grant assistance for this application.
Metro's consultant, CRA, Inc., employs experienced grant-writing staff and
works with Metro directly to assist Municipalities with writing grants. They
worked with Public Works staff for several months preparing this grant
application and the results of the first round of grant funding applications
should be available in early 2023. If the Project is not selected in the first
round, there is an additional round of State funding that the Project may be
eligible for.
11. INTERNALLY ILLUMINATED STREET NAME SIGN AND TRAFFIC
SIGNAL SAFETY LIGHT REPLACEMENT PROJECT - ET/Delgado – As part
of the Fiscal Year 2022-23 Budget, the City Council allocated funding to
replace all internally illuminated street name signs and traffic signal safety
lights found at all intersections citywide. Most of the current signs and lights at
these intersections have long surpassed their functional expiration;
incandescent bulbs are no longer being produced, and many of the sign panels
are beginning to fade due to sun damage. The new sign and safety light
hardware will feature light-emitting diode (LED) fixtures, which provide brighter
and more efficient illumination for the intersection when compared to the
1.A.a

current equipment. As part of the sign replacement, the panel design will be
updated to march the City’s template, which includes the windmill logo over a
white highway gothic typeface on a green background. Examples of the new
sign panels are shown in Exhibit A, and these signs are currently installed at
the Grand Avenue intersections of Summitridge Drive and Lavender Drive. The
Public Works Department recently issued a Request for Proposals (RFP) for
prospective contractors to submit bids to perform this work. Bids will close on
September 22, 2022, and staff anticipates awarding this Project to the selected
contractor by late October. Hardware procurement should commence shortly
thereafter, with sign and light replacements beginning in January 2023. All
work should be completed by June 2023.
12. LOCAL ROAD SAFETY PLAN AND HSIP GRANT – AE/Malpica –
Several options were presented by staff in order to apply for a cycle HSIP
Cycle 11 Projects and engaged a consultant to review the report and provide
recommendations for which potential projects could be considered. Based on
the consultant’s review, it was recommended that nine (9) intersections were
listed as potentials to be upgraded. The application has been completed for
submission and staff expects announcements to be forthcoming . If the City’s
application is selected, which can be as early as the summer of 2023, we
anticipate receiving the grant money by early 2024, or sooner. The total
engineer’s estimate cost to complete the Project is approximately $332,000,
out of which 90 percent is covered by HSIP with the City contributing 10
percent. Further updates will be provided to the Commission as they become
available.
Staff responded to general Commission questions and concerns regarding
various projects.
C/Plunkett moved, C/Sulakhe seconded, to receive and file the Monthly
Updates of Various Projects/Programs report. Motion carried by the following

VIII. ITEMS FROM COMMISSIONERS:
C/Plunkett thanked DWP/Liu and staff for responding to her concerns regarding the
parking difficulties at Summitridge Park.
When she was at the August 2nd Concerts in the Park, a neighbor asked if she would
mention that they feel the traffic light on Diamond Bar Boulevard and Sugarpine Place
is too long. AE/Malpica responded that staff was made aware of the concern and
resolved the issue. C/Plunkett received the flyer for the curb addressing service and
the company was a no-show. AE/Delgado responded that there is a non-profit
organization that has a permit from the City of Diamond Bar to repaint the curb
addresses. The contractor is currently performing this work at all addresses south of
Grand Avenue and is delayed due to the current roadway project.
Chair/Busteed inquired as to whether staff had looked into a concern regarding
pedestrian safety at the northbound right turn from Brea Canyon Road onto Diamond
Bar Boulevard. AE/Malpica has requested the consultan t to revisit the location two
additional times and provide staff with a recommendation that is forthcoming.
IX. SCHEDULE OF FUTURE CITY EVENTS:
As listed in the agenda and reported by Chair/Busteed.
ADJOURNMENT: There being no further business to come before the Traffic and
Transportation Commission, Chair/Busteed adjourned the meeting at 7:39 p.m. to Thursday,

B. Grand Avenue/Golden Springs Drive Intersection Improvements
As of January 2023, concrete footings and base have been completed for the west
tunnel. The installation of wall structural reinforcement lining is near completion in
anticipation of the concrete pour in the next couple of weeks. The west side tunnel is
anticipated to be completed by the end of this month.
C. Diamond Bar Boulevard/Kiowa Crest Drive Protective Left-Turn Warrant Study
The City's traffic consultant completed the left-turn signal warrant study at Diamond Bar
Boulevard and Kiowa Crest Drive. As reported in the past meeting, this study originated
due to previously reported accidents between left-turn movements and through traffic at
this intersection. The study concluded that this intersection location did not meet the
warrant thresholds for protected left-turn signals for both northbound and southbound
directions along Diamond Bar Boulevard due to low movement vol umes. It is
recommended to keep the existing permissive left-turn phasing.
D. Diamond Bar Boulevard Complete Streets Project
To date, the City has secured $3 million in Metro grant funding for construction. On
Wednesday, June 15th, the City applied for an additional $3.9 million of Cycle 6 Active
Transportation Program (ATP) grant funds, a program funded by the California
Transportation Commission (CTC) and managed by Caltrans. The grant results were
released on October 20, 2022. While the project scored well (87 out of 100 possible
points), the cutoff for projects that were awarded funding was 89 out of 100. The project
scored well in all areas except the Disadvantaged Community category. The City of
Diamond Bar is not a Disadvantaged Community as defined by the State, and therefore
received zero points for this category.
There is a second round of funding available through Metro's local allocation of $192.1
million. The results for this second round of funding are scheduled to be decided in May
of 2023. Staff is hopeful this project will be successful in this second round.
E. NTMP/Hawkwood Road Neighborhood – Neighborhood Traffic Management
Program
The final construction striping plan was shared with the residents with an online survey
to gain feedback on the design. Staff procured construction quotes for the
implementation of the approved plan and is in the process of awarding the construction
contract to the low bidder. Construction contract has been approved. Next step is to
schedule the work during the month of February. The project should be completed
within 2 weeks.

F. NTMP/Del Sol Lane Neighborhood – Neighborhood Traffic Management
Program
Construction began on December 8, 2022, and was completed on December 22, 2022.
All improvements were installed per plan and approved by City staff. Traffic data will be
collected six (6) months after the improvements were installed to determine if the
improvements have had the intended effect on speed and traffic behavior. This project
has been completed within budget.
G. Area 2 CBDG Curb Ramp Project
Construction began on October 10, 2022, and was completed on December 19, 2022.
All 16 ramps were installed per plan with the exception of 4 ramps that were relocated in
order to improve neighborhood drainage. This project has been completed under
budget.
H. Upcoming Utility Construction Projects
Staff approved plans and issued encroachment permits for several utility improvement
projects that are anticipated to start construction in the coming weeks:
• SoCalGas – Kiowa Crest Drive, from Eldertree Drive to Santaquin Drive
o Residential Gas Service Mainline Replacement

SUBJECT: Marked Crosswalk Study at Quail Summit Elementary
School
RECOMMENDATION: Receive and Concur
BACKGROUND/DISCUSSION:
Crossing guard services are to assure the safety of school -aged children, pedestrians,
parents, and others when crossing streets utilizing c rosswalks in the vicinity of their
respective schools during the school drop-off and pickup hours. The City requires all
crossing guards to be properly trained and supervised to carry out their responsibilities
at their designated post locations.
The City awarded a new three-year contract to All City Management Services (ACM) on
June 2022 to provide crossing guard services at 17 locations within the Walnut Valley
Unified School District and Pomona Unified School District. City’s crossing guards have
been providing services to the Quail Summit Elementary School for over 20 years at two
locations (Quail Summit Drive/Winterwood Lane & Forest Canyon Road near Paul C.
Grow Park (mid-block behind the school).
All City Management Services informed the City that they were unable to provide
service at the Forest Canyon location due to a missing marked or unmarked crosswalk.
ACM conveyed to staff that deploying personnel at a non -legally established marked or
unmarked crosswalk would create liabilities. Additionally, ACM’s insurance provider

limits their deployment of personnel to only legally established crossing. The City
agreed to conduct a crosswalk study and ACM agrees to resume service at this location
if a crosswalk is legally marked. Staff immediately convey ed this information to both
Walnut Valley School District and Quail Summit Elementary School principal. The
school principal was able to convey this information to all school parents at their back -
to-school night meeting, just before school resumed in early August 2022. Additionally,
the City posted a sign indicating that no crossing guard service is provided at the
subject location.
Staff retained one of the City’s on-call traffic consultants to conduct a marked crosswalk
study. The study, provided in Attachment 1, determined that due to low vehicular
volumes and low pedestrian activities, the requirement for a marked crosswalk and, as
a result, a crossing guard warrant was not met at the location. Additionally, staff looked
into potentially adding school signage along Forest Canyon Road, however, per CA
MUTCD, the school warning signage can be used with prima facie 25 MPH speed limits
that are contiguous to a school building or school grounds. Since Forest Canyon Road
is contiguous to the Paul C. Grow Park and not the school grounds, school warnings are
not applicable either.
Later this month, PW staff will provide an update to ACM and to both, the Walnut Valley
School District and Quail Summit Elementary School staff.

Date: October 20, 2022
Subject: Marked Crosswalk Study at Quail Summit Elementary School
1.0 BACKGROUND
Kimley-Horn and Associates, Inc. (“Kimley-Horn”) has been retained by the City of Diamond Bar to
prepare a marked crosswalk study along Forest Canyon Drive in the vicinity of Quail Summit
Elementary School. The study assesses the need for a crosswalk in the vicinity of 23288 Forest Canyon
Drive and the driveway to Paul C. Grow Park (“study location”). The parking lot of the park provides
rear access to Quail Summit Elementary School and is utilized during school pickup and drop-off
periods. Exhibit 1 shows the school and surrounding roadway network.

As part of this study, data was collected in the form of traffic counts and field observations during the
school drop-off and pick-up periods. Based on these data collection efforts and a review of relevant
published guidelines, such as the Federal Highway Administration (FHWA) Field Guide for Selecting
Countermeasures at Uncontrolled Pedestrian Crossing Locations and California Manual on Uniform
Traffic Control Devices (CA MUTCD), recommendations were identified.
2.0 DATA COLLECTION
This section describes the data collection efforts undertaken in support of this study, including traffic
counts and field observations.
2.1 Traffic Counts
Traffic counts were collected along Forest Canyon Drive during the school pick-up and drop-off periods
for vehicles, bikes, and pedestrians at the following locations:
• Meadow Glen Road & Forest Canyon Drive
• Paul C. Grow Park Driveway & Forest Canyon Drive
• High Bluff Drive & Forest Canyon Drive
Counts were taken on Thursday, August 18th, 2022, between 7:00 to 9:00 AM for the morning drop-off
period and 11:00 AM to 2:00 PM for the pick-up period. The traffic counts are included in Appendix A.
Vehicle Traffic
Vehicle counts are summarized for the morning drop-off peak hour (7:30 – 8:30 AM) in Table 1 and the
mid-day pick-up peak hour (12:45 – 1:45 PM) in Table 2. Overall vehicle volumes were higher at each
intersection during the morning drop-off peak hour than during the afternoon pick-up peak hour. Along
Forest Canyon Drive, west of Paul C. Grow Park Driveway, 139 vehicles were observed during the AM
drop-off hour and 84 vehicles were observed during mid-day pick-up hour. Additionally, around 15
vehicles utilized the Paul C. Grow Park Driveway during both the morning drop-off peak hour and the
mid-day pick-up peak hours.

2.2 Field Observations
A field visit was conducted to observe conditions during school drop-off and pick-up periods based on
the school bell schedule. Observations were made on Wednesday, August 24th, 2022, during the
following 30-minute periods:
• Drop-Off: 7:50 to 8:20 AM - morning bell at 8:20 AM
• Pick-Up: 2:45 to 3:15 PM - dismissal at 1:30 PM for Kindergarten; 2:45/2:50 PM for 1st – 5th
grades
The following observations were made during the field visit at Forest Canyon Drive and the Paul C.
Grow Park driveway.
Pedestrian Activity
• Five (5) students were observed crossing Forest Canyon Drive at the Paul C. Grow Park
driveway during the drop-off period.
• A parent in a nearby house with two (2) children attending Quail Summit Elementary School
indicated that around 15 students will typically cross at this location during the drop-off and
pick-up periods.

• School staff indicated around 20 children utilize the rear access gate at the Paul C. Grow
Park driveway during drop-off and pick-up periods.
Exhibit 2: Parent with children crossing Forest Canyon Drive at Paul C. Grow Park Driveway
Vehicle Activity
• Parents utilize the parking lot for Paul C. Grow Park to wait for their children during the pick-up
period.
• No extensive queuing or vehicle back-up was observed at this location during either period.
• School staff suggested that as the schoolyear progresses and word spreads, more parents will
utilize this location.
• During the pick-up period, a posted school staff member ensures that parents are not
blocking the Paul C. Grow Park driveway and abiding by posted parking regulations.
• Speeding is a concern in both directions on Forest Canyon Drive, but particularly in the
westbound direction due to the downhill slope, lack of school signage, and lack of houses or
driveways on the north side of the street east of the Paul C. Grow Park driveway.

Former Crossing Guard
• School staff indicated that a crossing guard was posted just east of the Paul C. Grow Park
driveway during the last schoolyear, utilizing cones to delineate where to cross.
• Both school staff and parents that were spoken to voiced appreciation for the crossing guard
presence and spoke in favor of a marked crosswalk at this location.
• Generally, younger students would arrive/depart with parents, while older students would
walk by themselves.
• With the absence of a crossing guard this year, school staff indicated that children are not
allowed to cross Forest Canyon Drive at this location without an adult present.

Other
• School staff indicated that on weekends, sports games held at Paul C. Grow Park draw heavy
pedestrian activity as people park along and cross the street at numerous locations to and from
the park and their vehicles.
3 .0 EXISTING LITERATURE
3.1 Crosswalk Markings
Per Section 7C.02 of CA MUTCD, crosswalks should be marked at all intersections on established
routes to a school where there is substantial conflict between motorists, bicyclists, and student
movements; where students are encouraged to cross between intersections; where students would not
otherwise recognize the proper place to cross; or where motorists or bicyclists might not expect
students to cross.
Per Section 3B.18 of CA MUTCD, at non-intersection locations, crosswalk markings legally establish
the crosswalk. Crosswalk lines should not be used indiscriminately. An engineering study should be
performed before a marked crosswalk is installed at a location away from a traffic control signal or an
approach controlled by a STOP or YIELD sign. The engineering study should consider the number of
lanes, the presence of a median, the distance from adjacent signalized intersections, the pedestrian
volumes and delays, the average daily traffic (ADT), the posted or statutory speed limit or 85th-
percentile speed, the geometry of the location, the possible consolidation of multiple crossing points,
the availability of street lighting, and other appropriate factors. Mid-block pedestrian crossings are
generally unexpected by the motorist and should be discouraged unless, in the opinion of the engineer,
there is strong justification in favor of such installation.
Further, per California Vehicle Code (CVC) 21106, local authorities, by ordinance or resolution, may
establish crosswalks between intersections.
3.2 Crossing Supervision
Per Section 7D.02 of CA MUTCD, adult crossing guards may be used to provide gaps in traffic at school
crossings where an engineering study has shown that adequate gaps need to be created, and where
authorized by law. Adult crossing guards normally are assigned where official supervision of school
pedestrians is desirable while they cross a public highway, and at least 40 school pedestrians for each
of any two hours (not necessarily consecutive) daily use the crossing while going to or from school.
Specifically, adult crossing guard may be used in urban areas where the vehicular traffic volume
exceeds 350 during each of any two hours (not necessarily consecutive) in which 40 or more school
pedestrians cross daily while going to or from school at uncontrolled crossings where there is no
alternate controlled crossing within 600 feet.
4.2.a
Packet Pg. 39 Attachment: Marked Crosswalk Study - Quali Summit Elementary School (Marked Crosswalk Study at Quail Summit Elementary School)
Page | 7
4 .0 RECOMMENDATIONS
Crosswalks are marked at intersections where there is substantial conflict between vehicle and
pedestrian movements, where significant pedestrian concentrations occur, where pedestrians could
not otherwise recognize the proper place to cross, and where traffic movements are controlled. Mid-
block crosswalks should only be used where necessary to direct pedestrians along the safest route.
Based on traffic data, 139 vehicles were observed during the AM drop-off hour and 84 vehicles were
observed during mid-day pick-up hour along Forest Canyon Drive, west of Paul C. Grow Park Driveway.
Further, eight (8) and four (4) pedestrians were observed to cross Forest Canyon Drive at the study
location during the AM drop-off and mid-day pick up hour, respectively. These vehicle volumes and
low pedestrian activity indicate that a marked crosswalk/adult crossing guard is not required at
the study location at this time.
In the event that pedestrian crossings in the immediate vicinity of the Park Driveway increases
significantly (for instance, more than 40 pedestrians in any two hours of a day), the following strategies
could be considered in order to improve safety for crossing Forest Canyon Drive at the Paul C. Grow
Park driveway:
• Install a yellow ladder crosswalk across Forest Canyon Drive approximately 40 feet east of the
Paul C. Grow Park driveway. Install “School Crosswalk Warning Assembly B” sign on either
end of the crosswalk per latest CA MUTCD.
o On either end of the proposed crosswalk, construct Case C pedestrian curb ramps with
ADA detectable warning surfaces per latest California Department of Transportation
(Caltrans) Standard Plan A88A.
o Alternatively, construct curb extensions at either end of the crosswalk with Case A
pedestrian curb ramps with ADA detectable warning surfaces per Caltrans Standard
Plan A88A.
• Install advance yield markings 50 feet ahead of the proposed crosswalk in either direction along
with CA MUTCD “Yield Here to Pedestrians” sign (R1-5).
• Install “SLOW SCHOOL XING” yellow pavement markings 100 feet in advance of the proposed
crosswalk in either direction.
• Install CA MUTCD “School Advance Warning Assembly D” sign at least 100 feet in advance of
the proposed crosswalk in either direction.
• Consider posting a crossing guard at the location of the proposed crosswalk per Chapter 7D.02
of CA MUTCD.
• Consider installing CA MUTCD “School Warning Assembly A” signage on Forest Canyon Drive.
These optional improvements are shown in the concept plans included in Appendix B.

SUBJECT: Marked Crosswalk Study at Castle Rock Elementary
School
RECOMMENDATION: Receive and Concur
BACKGROUND/DISCUSSION:
In August 2022 staff received a request to assess the existing crosswalks within the
vicinity of Castle Rock Elementary School for the need to update the existing
crosswalks along Castle Rock Road between Cold Spring Lane and Cool Springs Drive.
All current crosswalks at Cool Springs Dr.; at front of school; at Bronco Ln. and at Cold
Spring Ln. were installed as part of the 1998 Citywide School Traffic Circulation Study,
except the intersection at Trigger Ln. Staff retained the City’s traffic consultant to
perform a marked crosswalk study for potential improvements. See Attachment 1.
Based on the study, the recommendations are as follows:
• Castle Rock Road/Cold Spring Lane – install a new yellow ladder crosswalk at
the south leg and stop sign relocation
• Castle Rock Road/Trigger Lane – Install a new yellow ladder crosswalk at the
west leg across Trigger Ln
• Castle Rock Road/Bronco Lane – Install a new yellow crosswalk at the west leg

across Bronco Ln. with new ADA-compliant curb ramp at the east end of the
crosswalk spanning Castle Rock Road. Add a new 20 -feet red curb in either
direction of the crosswalk spanning Castle Rock Road and install ne w signage
• Castle Rock Road/In-front of School – Relocate existing crosswalk to
approximately 40 feet south of its current location to allow for ADA-compliant
curb ramps. Add a new 20-feet red curb in either direction of the crosswalk
spanning Castle Rock Road and install new signage; and
• Castle Rock Road/Cool Springs Drive – Relocate the existing crosswalk
spanning Castle Rock at the north leg to the south leg with new ADA -compliant
curb ramp and install new signage.
All existing Texas botts dots along Castle Rock Road yellow centerline will be removed.
Crossing guards are posted at approved crosswalk locations to assure the safety of
school-aged children, pedestrians, parents, and others when crossing streets utilizing
crosswalks in the vicinity of their respective schools. There are two (2) crossing guards
currently providing crossing support at Castle Rock Road/In-front of the school and
Castle Rock Road/Cold Spring Lane. There is no need to relocate any of the existing
crossing guards per the study.
RECOMMENDATION:
It is recommended that the Traffic and Transportation Commission receives the staff
report and concurs with the recommendations prepared in the October 27, 2022 Kimley -
Horn’s Marked Crosswalk Study at Castle Rock Elementary School.

1.0 BACKGROUND
Kimley-Horn and Associates, Inc. (“Kimley-Horn”) has been retained by the City of Diamond Bar to
prepare a marked crosswalk study in the vicinity of Castle Rock Elementary School. The study
assesses the need for a marked crosswalk in the vicinity of Castle Rock Road and Trigger Lane.

As part of this study, roadway characteristics were examined along Castle Rock Road using aerial
imagery and Google Street View. Additionally, field observations were conducted during the school
morning drop-off and afternoon pick-up periods. Based on these data collection efforts and a review of
relevant published guidelines, such as the Federal Highway Administration (FHWA) Field Guide for
Selecting Countermeasures at Uncontrolled Pedestrian Crossing Locations and California Manual on
Uniform Traffic Control Devices (CA MUTCD), recommendations were identified for the proposed
crosswalk location and its surroundings, including traffic calming devices, pavement markings, and
signage to be installed.
2.0 DATA COLLECTION
This section describes the data collection efforts undertaken in support of this study, including an
examination of existing roadway characteristics and field observations.
2.1 Roadway Characteristics
The segment of Castle Rock Road between Cold Spring Lane and Cool Springs Drive is approximately
1/3 of a mile in length and oriented northeast-southwest. The roadway is considered a local street in
the City’s General Plan, with one travel lane in each direction. There is a yellow centerline north of the
school driveway and no centerline south of the school. The speed limit is 25 mph and there is curbside
parking on both sides of the street. Besides Castle Rock Elementary School, the surrounding land uses
are single-family residential in nature.
Marked school crosswalks are present at the following intersections along this segment of Castle Rock
Road.
• Cold Spring Lane (north, east, west legs)
• Bronco Lane (south leg)
• School driveway (exit only, south leg)
• Cool Springs Drive (north, west legs)
It was noted that the east end of the crosswalk at Bronco Lane and both ends of the crosswalk at the
school driveway currently do not have curb ramps.
Within 500 feet of the school, each of these school crosswalks are accompanied by “SLOW SCHOOL
XING” yellow pavement markings, “School Crosswalk Warning” Assembly B signage, and “School
Advance Warning” Assembly D signage.
A series of speed cushions with
advance warning pavement markings
are also present along this stretch of
Castle Rock Road. Additionally, Botts’
dots (as shown in Exhibit 2) are
present along the yellow centerline
near the school parking lot driveway,
at Bronco Lane, and at Cold Spring
Lane, with some showing damage due
to impacts from vehicles.

2.2 Field Observations
A field visit was conducted to observe conditions during school drop-off and pick-up periods based on
the school bell schedule. Observations were made on Wednesday, August 24th, 2022, during the
following 30-minute periods:
• Drop-Off: 7:50 to 8:20 AM - morning bell at 8:20 AM
• Pick-Up: 12:50 to 1:20 PM – early dismissal on Wednesdays at 12:50 PM (1st through 5th
grades)
The following observations were made during the field visit along Castle Rock Road between Cold
Spring Lane and Cool Springs Drive:
• Crossing guards are typically posted at the intersections of Castle Rock Road with Cold Spring
Lane and the school driveway during school drop-off and pick-up.
• School traffic circulation during the morning drop-off and afternoon pick-up periods is directed
by school staff. Parents in vehicles are directed southbound along Castle Rock Road to conduct
curbside passenger loading activities curbside at the school.
• Parents in vehicles traveling northbound along Castle Rock Road are not allowed to stop for
passenger loading activities. They must utilize curbside parking and walk with their children to
a marked crosswalk.
Southbound vehicles queuing along Castle Rock Road frequently stop in and block the
crosswalks at both Cold Spring Lane and at Bronco Lane during both morning drop-off and
afternoon pick-up periods.
Exhibit 3: Southbound queuing vehicles on Castle Rock Road blocking crosswalks at Cold Spring Lane
• Parents were observed double parking along Castle Rock Road. This blocks visibility of
oncoming vehicles for the crossing guards and pedestrians.

Exhibit 4: Vehicles double-parking on Castle Rock Road
• Parents park vehicles along Trigger Lane and Bronco Lane and walk with children to the
school.
• Most pedestrian activity occurs along the west side of Castle Rock Road, particularly during
the morning pick-up period.
• Few parents or students were observed using the crosswalk at Bronco Lane to cross Castle
Rock Road during the morning drop-off period or afternoon pick-up period.
• Crossing guard at school driveway primarily assisting parents and students walking from
south of the school, though some parents were observed parking on east side of Castle Rock
Road and utilizing this crosswalk.
• During afternoon pick-up, parents and students were observed crossing Castle Rock Road at
school driveway and heading north or south.
• According to the crossing guards:
o Afternoon pick-up traffic is more congested and chaotic than morning drop-off.
o Parents will actively disobey crossing guards and school staff.
o More cones are needed by school to prevent parents from parking vehicles too close
to the crosswalk or from blocking private driveways.
o Would desire a marked crosswalk on south leg of intersection at Cold Spring Lane.
