2. Collisions: December 2017, January & February 2018
3. Street Sweeping: December 2017, January & February 2018
C/Gonzalez asked if enforcement concerns were addressed by the Commission
directly to the Sheriff's Department for particular areas of the City. Chair/Quan
responded that the Commission does not articulate directly with the Sheriff's
Department. PWD/Liu stated that questions and concerns regarding public safety
should be directed to the City Manager's office which oversees the Sheriff's contract,
Fire Department contract and overall public safety program.
Chair/Quan said she is always relieved to see the numbers down.
C/Mehta asked why the total number of citations was down from 960 in January to
688 in February and PWD/Liu responded that the main reason is because for the
MARCH 8, 2018 PAGE 3 T&T COMMISSION
VI.
11r11I
months of December and January streets are scheduled for street sweeping on a
weekly basis, and beginning with the month of February the schedule reverts to a bi-
weekly basis, which accounts for the nearly 50 percent reduction.
C/Mehta moved, C/Gonzalez seconded to receive and file the Traffic Enforcement
Update for December 2017, January & February 2018. Motion carried by the
following Roll Call vote:
AYES: COMMISSIONERS: Gonzalez, Mehta, Washington,
VC/Garg, Chair/Quan
NOES: COMMISSIONERS: None
ABSENT: COMMISSIONERS: None
C/Gonzales asked if there was a motor officer assigned to Diamond Bar and PWD/Liu
said that in terms of the City's traffic enforcement program, for many years the City
had a motor officer (Sergeant) and when he retired, traffic enforcement was
reassigned to a black and white unit dedicated to certain traffic enforcement duties.
PWD/Liu said that staff would arrange a time to give C/Gonzalez an overall
understanding of how the Public Safety Program is structured and managed is the
City of Diamond Bar.
C/Gonzalez said his question was that because the citations are down because there
is a direct correlation between accidents and the citations that are written, perhaps
the City could talk with the Sheriff's Department and ask fora motor to be assigned to
the City of Diamond Bar. PWD/Liu said there are two components involved in this
statistical report. With respect to the street sweeping enforcement activities, there is
a dedicated Community Services Officer (CSO) who works full time in the City of
Diamond Bar. Parking citations numbers are a direct result of his enforcement
efforts. Any other traffic related issues are the responsibility of different assigned
deputies.
OLD BUSINESS: None
NEW BUSINESS: None
VIII. STATUS OF PREVIOUS ACTION ITEMS: None
IX.
ITEMS FROM COMMISSIONERS: None
X. INFORMATIONAL ITEMS:
A. Traffic Signal Infrastructure Upgrades Project, Phase III — AE/Malpica —
Phase III is the final phase of enhancements to the City's infrastructure system
by replacing some of the existing traffic controllers, replacing copper with new
fiber optics to enhance communication, switches, wireless radios, and other
items in the traffic signal cabinets. The project is currently being advertised
and has a bid due date of Monday, March 12. The Engineer's estimate for this
project is $409,000.
MARCH 8, 2018 PAGE 4 T&T COMMISSION
B. Adaptive Traffic Control Signal System —AE/Malpica —This project involves
enhancements to the existing Traffic Control Signal System. The primary goal
of the system is to reduce delay, manage queue lengths, and reduce stopping,
travel time and side street delays along the main arterials. The Request for
Proposal (RFP) was released this week inviting companies/Vendors to submit
proposals to furnish, install and integrate the system along the three main
arterials (48 intersections). Bids are due on March 30tH
C. Copley Drive/Golden Springs Drive Intersection Enhancements —
AE/Malpica — This project was approved by the City Council at its February
20th City Council meeting with the contract awarded to PTM Engineering, Inc.
The contractor is currently working with staff to schedule a pre -construction
meeting. Enhancements for this intersection will include the west bound left
turn at Copley Drive on Golden Springs Drive being changed from a
protective/permissive left turn to protective only to improve traffic circulation in
the intersection. In addition, three (3) curb ramps, newvideo detection system
and CCTV cameras, signage, and one signal pole will be upgraded to
accommodate the new protective only left turn. Construction will commence
immediately after the pre -construction meeting.
AE/Malpica further stated that for the signals there would be very little concrete
work. The median's nose located west of that intersection is encroaching into
the crosswalk which will involve removing the nose and push it back and make
it clear for pedestrians to use the full width of the crosswalk. No restriping will
be needed.
D. City Entry Monument Signs — AE/Beshay — There are two new monument
signs proposed along Diamond Bar Boulevard south of Temple Avenue and
Golden Springs Drive west of Calbourne Drive. Plans and Specs have been
completed and the project will be advertised next week with bid opening in
early April. Construction is scheduled to commence the end of April.
E. Pathfinder Road Street Rehabilitation Project (LA County)—AE/Beshay—
Pathfinder Road between Peaceful Hills Road and Canyon Ridge within the
City of Diamond Bar will be cold -milled and resurfaced with new pavement.
This project is anticipated to be completed in early April.
F. Citywide Drainage Improvement Project — Phase I and Phase II —
AE/Beshay — This project was advertised on February 28th with bid opening
scheduled for March 14th. Construction commences mid to late April.
G. Lemon Avenue Interchange Project —AE/Malpica — Construction continues
on the westbound and eastbound on and off ramps on the SR60 at Lemon
Avenue near Golden Springs Drive. The ramps should be open soon. Due to
forecasted rain this weekend, the scheduled 55 hour closure of the number 3
and 4 lanes on the eastbound SR60 was canceled. It will likely be scheduled
for the March 16 through 19 weekend depending on Caltrans approval.
MARCH 8, 2018 PAGE 5 T&T COMMISSION
Overall, this cancellation will not delay the westbound on ramp and eastbound
off ramp openings which are scheduled for March 318t. The project remains on
track for completion in the summer of 2018. Once the new eastbound on
ramp at Lemon Avenue is constructed, the existing eastbound onramp at Brea
Canyon Road will close (projected for May/June 2018).
H. SRS7/60 Confluence Project—AE/Malpica —The westbound loop on ramp at
Grand Avenue is scheduled to be opened on March 26th. The contractor will
attempt to work this weekend before the forecasted rain on Saturday evening
in an effort to keep the March 26th opening as scheduled. The overall project
for the westbound loop onramp and westbound off -ramp at Grand Avenue is
60 days ahead of schedule with full completion projected for May 2018, barring
any unforeseen conditions and weather delays. The westbound slip on ramp
is progressing with Edison working on the relocation of the facilities. This
phase of the project was severely delayed due to this relocation and nesting
birds but has since re -commenced with construction and will move toward
completion by the end of the calendar year.
I. Grand Avenue/Golden Springs Intersection Improvements Update —
AE/Beshay — This project is part of the overall Confluence Project. The
improvements will be to widen the intersection at Grand Avenue and Golden
Springs Drive to create the following configurations: Add a third through lane
on both sides of Grand Avenue (northbound and southbound) north of Golden
Springs Drive, add a dedicated right -turn lane on Golden Springs Drive in the
westbound direction at the golf course parking lot corner and add a through -
lane on Grand Avenue in the northerly direction at the Mobile Gas station
corner. All right-of-way acquisitions are being done on the golf course side
only and none on the business side (Chili's and Mobil). While this project is
entirely within the City of Diamond Bar, the City of Industry is funding the
project and taking the lead in the design phase. Similar to the Grand
Avenue/Diamond Bar Boulevard intersection elements, staff is working with a
landscape designer to provide landscape plans for the intersection that
incorporates streetscape elements including decorative pavers, crosswalks,
street trees, and post and rail fencing. The consultant is working to enhance
the lighting for the seal panels to improve the intersection and once the lighting
plan is completed, the plans will be finalized and sent to City of Industry's
designer/engineer to incorporate those changes within their plans.
J. Morning Canyon Road Rehabilitation Project —AE/Beshay—The contractor
requested repair of the roadway to be completed in late spring/early summer.
Cold weather, rain and shade trees in the parkway do not provide adequate
conditions for the repair work and the contractor has asked to be able to do it
in the warmth of late spring/early summer when the curing process would be
much faster. When work is completed, the City will file the Notice of
Completion.
K. TR 63623 — Southpointe Residential Development/Larkstone Park —
AE/Aoun — This is a residential development with 99 new single family
MARCH 8, 2018 PAGE 6 T&T COMMISSION
residential units in the hills near the South Pointe Middle School within a gated
community. The developer is currently building Phase 7 of 10 and are in the
process of pulling permits for Phases 9, 10, and the build -out phase. Larkstone
Park is a new public park that is being constructed as part of this development.
The park is in the final phases of inspection and the contractor continues
readying the park so that it can be opened to the public.
VC/Garg asked the date of opening for Larkstone Park and AE/Aoun
responded that there is no exact date as of this moment. There are a few
items being taken care of with Edison to provide power to the park and the
contractor is finishing items as well. It is likely the park will open during
summer.
Diamond Bar Ranch Shopping Center (Sprouts/Chipotle/Coffee
Bean/Ross/The Habit & McDonald's) — Development Update - AE/Aoun —
Sprouts, Chipotle and Coffee Bean and Tea Leaf have opened. Ross is
planning to open this Friday and the final construction for the plaza will be for
The Habit restaurant. The Habit pad is close to pulling final grading permits
and commence grading within the nextfewweeks. The McDonald's within that
center is being remodeled and plans are that if all goes well, it will reopen in
early April. They are currently paving the parking lot and preparing the
restaurant interior for opening.
Chair/Quan commented that the center looks really nice. She spends a lot of
time at Sprouts and is excited about the Ross opening this Friday. The other
day she was getting gas at Sam's Club in Chino and coming back to Diamond
Bar and she noticed how nice the median and improvements look whetheryou
arrive via Golden Springs, Diamond Bar Boulevard or some other route. The
site really ties the City together very nicely.
PWD/Liu explained that the section of Diamond Bar Boulevard from the on/off
ramps to Golden Springs Drive will be redone in the next year or two. There
are conceptual plans in development, there have been some community
meetings where staff received feedback from residents and businesses. In the
near future, once the plans are finalized, that section of Diamond Bar
Boulevard will be enhanced to create a synergy that will hopefully attract
people into that area to shop and dine more frequently rather than going
outside of the City.
Chair/Quan felt it was working because there is kind of a "wow" factor when
one drives into the City and she is glad all of the medians do not all look the
same. It holds one's interest when coming off the SR57 down Diamond Bar
Boulevard where one sees animal shapes and windmills. It is quite pleasing
and thanks to everyone involved for improving the City.
VC/Garg asked if staff had followed up with Gail Dunn regarding her parking
issues on Walnut Street. PWD/Liu said that staff is following that housing
development very closely. The last information that was confirmed is that their
MARCH 8, 2018 PAGE 7 T&T COMMISSION
City of Industry planning commission rejected the proposal and that the
developer intends to appeal that decision to their city council. At this morning's
meeting of City of Industry City Council's meeting, the couple who spoke here
attended that meeting to remind the Industry City Council to not forget about
the parking and traffic concerns they have expressed for some time. Staff
wants to be sure that if there are any impacts or mitigation measures required
as a result of the project, staff will work to address those impacts.
XI. SCHEDULE OF FUTURE CITY EVENTS: As noted in the agenda. Chair/Quan
pointed out upcoming events such as the E -Waste Roundup. She encouraged
everyone to spring forward with their clocks this weekend. PWD/Liu pointed out that
the March 20, 2018 City Council Meeting (Item D) has been adjourned to April 31d due
to lack of quorum. In addition, the Mayor's State of the City will be held at the
Diamond Bar Center on Wednesday, March 28th at 6:30 p.m. (Reception at 6:00 p.m.)
PWD/Liu spoke about the updated Commissioners Handbook and pointed out various
items and information contained within the document.
PWD/Liu stating that beginning with the April agenda, the format will be revised to be
consistent with the Parks and Recreation Commission and as much information as
possible with respect to Informational Items will be given to the Commission in written
report form. As in the past, Action items will be acted on separately with staff
providing written reports and recommendations.
ADJOURNMENT: There being no further business to come before the Traffic and
Transportation Commission, Chair/Mehta adjourned the meeting at 7:53 p.m.
The foregoing minutes are hereby approved this day of 2018.
Respectfully Submitted,
David G. Liu, Secretary

TRAFFIC AND TRANSPORTATION COMMISSION
MEMORANDUM
DATE: April 5, 2018 MEETING DATE: April 12, 2018
TO: Chair and Members of the Traffic and Transportation Commission
FROM: Christian Malpica, Associate Engineer
VIA: David G. Liu, Director of Public Works/City Engineer p
SUBJECT: Castle Rock Road Neighborhood Traffic Management Program (NTMP)
between Fountain Springs Road and Cold Spring Lane
BACKGROUND/DISCUSSION:
At the October 2017 Traffic & Transportation Commission meeting, a resident from
Castle Rock Road expressed his traffic concerns along Castle Rock Road between
Fountain Springs Road and Cold Spring Lane. Castle Rock Road is being impacted by
school traffic during school rush hours. The neighboring schools are Castle Rock
Elementary School which is located south of Cold Springs Lane and Evergreen
Elementary School located north of Fountain Springs Road (see attached Vicinity Map).
Staff reached out to the resident after the meeting to obtain additional details regarding
his traffic concern and provided him with an information packet on the City's
Neighborhood Traffic Management Program (NTMP).
In February 2018 staff received a formal request for traffic calming tools along Castle
Rock Road with a petition of 51% of the residents in the neighborhood in favor of
launching the NTMP as required by the NTMP guidelines. For tonight's meeting,
approximately 120 invitation letters were sent to the residents living along Hidden Pines
Drive, Hipass Drive, Lasso Drive, Hideout Drive, Silver Cloud Drive, Sunbright Drive and
Castle Rock Road (see attached Study Area Map).
As part of tonight's presentation, staff will be introducing the program to residents along
these affected streets and give them the opportunity to express their traffic concerns.
Upon conclusion of the meeting, staff will follow up with speed and volume data
collection based on the comment received and subsequently a conceptual plan of
proposed tools for the roadway will be prepared. A second meeting will be held at a
later date with the neighborhood to present the conceptual plan once it has been
completed.
RECOMMENDATION:
It is recommended that the Traffic and Transportation Commission receive staff's
presentation and public comments on the Castle Rock Road NTMP.

E. Pathfinder Rehabilitation (LA County)
The cold milling and the final paving of the road have been completed along

City of Diamond Bar jurisdiction. This project is being completed in conjunction
with Los Angeles County as a cost saving measure since they are rehabilitating
Fullerton Road and Pathfinder Road within their jurisdictional limits. The project is
anticipate to be completed Mid -April.

The award of the project was approved at the April 3'd Council meeting to wright
Construction for the total base bid amount of $400,873.20, plus a contingency
amount of $40,087.32, for Contract Change Orders to be approved by the City
Manager, for a total authorization amount of $440,960.52. Construction will start
in late April.
G. Lemon Avenue Interchange Project
The WB on-ramp and EB Off -ramp are scheduled to be opened in the near future.
The simultaneous closure of the EB off -ramp at Brea Canyon Road will also occur
once the new EB off -ramp at Lemon Ave. is opened. The existing EB on-ramp at
Brea Canyon Road will remain open until the new EB on-ramp at Lemon Ave. is
opened in summer. Paving of the new EB on-ramp will take place this weekend
with a 55 -hour closure of the #3 & #4 eastbound lanes between Fairway and Brea
Canyon Road beginning 9:OOpm on Friday, April 6th to 5:OOam Monday, April 9th.
H. SR -57/60 Confluence Project
Phase I — New WB Slip Ramp: The new WB slip ramp was able to resume
construction with Edison working on the relocation of their facilities. This ramp is
expected to be opened in the fall, barring any further unforeseen circumstances.
z
Phase II — Reconstruction of the existing WB off -ramp and WB loop on-ramp: The
WB loop on-ramp at Grand Ave. along SR 57/60 was re -opened on Monday, March
26th. Vehicles traveling northbound on Grand Ave. are now able to access the WB
on-ramp. However, access to the ramp is still closed for vehicles traveling
southbound on Grand Ave. Detours are in place for vehicles to use Grand Crossing
to Baker Parkway to Brea Canyon Road to the WB on-ramp at that location for
vehicles using southbound Grand Ave. Additionally, the WB off -ramp at Grand
Ave. is still restricted to right turn only. All restrictions for the WB on-ramp and off -
ramp are expected to be removed by late April or May.
Grand Avenue/Golden Springs Drive Intersection Improvements
Referred to as Phase IIA for the SR 57/60 Confluence Project, the final design
continues with construction scheduled to begin in January 2019. Industry will
finalize all plans and specs and is preparing to go out to bid in June 2018. The
landscape design for this project is scheduled to be presented to the City Council
at a study session on April 17tH
J. Morning Canyon Road Rehabilitation Project
The contractor requested repair of the roadway to be completed in late
spring/early summer. Cold weather, rain and shade trees in the parkway do not
provide adequate conditions for the repair work and the contractor has asked to
be able to do it in the warmth of late spring/early summer when the curing
process would be much faster. When work is completed, the City will file the
Notice of Completion.
K. TR 63623 — Southpointe Residential Development/Larkstone Park
The first 7 phases of the housing development have been finalized. The developer
has modified the access gate on Morning Sun Drive to ensure it is an entrance
only gate. Residents of the South Pointe Development will be able to enter the
development from Morning Sun, but not exit. Larkstone Park is close to completion.
Final inspections are taking place over the next month to review the final changes.
L. Diamond Bar Ranch Shopping Center (Sprouts/Chipotle/ Coffee Bean/ Ross/
The Habit) & McDonald's Development
The Habit Pad has been approved to begin grading. No update has been received
regarding who could be occupying the empty tenant spaces next to Ross and
Sprouts. McDonalds is nearing completion as well. Opening day has been pushed
to the middle of April.
M. Diamond Bar Blvd. Complete Streets Corridor
The conceptual design with two alternatives has been completed. Staff will be
presenting both alternatives as well as the public input received at the September
2017 open house to the City Council at a study session on April 17th. The goal is
to receive direction from the City Council on the preferred alternative in order to
complete construction drawings and specifications. Once the final Plans, Specs
and Estimates are submitted, staff will diligently work on grant funding
opportunities to fund the approximately $4.7 Million Project. Construction is
currently programmed to begin in FY19-20.
