Gail Dunn, 20124 E. Walnut Drive South, lives near the Sikh Temple where Walnut
Drive East turns in to Flintgate Drive. She is concerned about the City of Industry's
proposal to build 25 homes across from her house because parking is already scarce.
She asked if the City could do permit parking on the Diamond Bar side of the street
and install speed bumps in the street to slow down drivers.

PWD/Liu responded that staff was recently made aware of the proposed 25 single
family development and has been monitoring the planning efforts and coordinating
with Industry staff and their consultants. As the speaker mentioned, this item was
before the City of Industry Planning Commission earlier this week and was continued
to next Tuesday. Staff is aware that parking is potentially an issue. Staff will continue
to monitor the proposed development and stay informed of what is being proposed
and work with neighborhood residents. If traffic mitigation measures are found to be
necessary, staff will bring its recommendations to the Commission.
ITEMS FROM STAFF:
A. Traffic Enforcement Update:
1. Citations: November & December 2017, January 2018
2. Collisions: November & December 2017, January 2018
3. Street Sweeping: November & December 2017, January 2018
Mrs. Dunn, 20124 E. Walnut Drive South spoke again to address her concerns about
citations on east Walnut Drive south. Several cars are left parked on the street during
street sweeping days and they never get cited. PWD/Liu said staff would look into the
matter and would be in touch with the resident.
C/Garg moved, C/Washington seconded to receive and file the Traffic Enforcement
Update for November & December 2017 and January 2018. Motion carried by the

VII. ITEMS FROM COMMISSIONERS:
1,70"
Chair/Mehta stated that when he takes a right or left turn into the Sprouts parking lot,
the driveway is not equally divided and he has seen drivers confused about which
way to turn when leaving the center. There is no demarcation as to which lane allows
February 8, 2018 PAGE 3 T&T COMMISSION
a right or left turn. AE/Aoun responded that there is striping at the beginning of the
driveway. When exiting, the striping indicates either straight and left, or right turns.
- The striping is offset from the center of the decorative concrete because there are
existing traffic loops for the signal, and vehicles were not moving forward enough to
be detected by the loops. Therefore, the striping was installed as a temporary
measure. Staff has required the development to install a video detection camera so
that the loops are no longer needed. The camera has been installed and staff is in
the process of modifying and programming it. Once programming is complete, the
camera will detect the traffic if vehicles stay in the center of the driveway. Also, when
completed, the striping will be removed so there will be no confusion. On the right
side when exiting, there will continue to be two lanes because there has to be both a
left and right turn lane. Staff will verify that the driveway width can accommodate two
lanes to exit while staying centered.
VIII. INFORMATIONAL ITEMS:
A. Traffic Signal Infrastructure Upgrades Project, Phase II through Phase III
— AE/Malpica — The Plans and Specifications for Phase III have been
completed and are currently under review. Upon completion of the review, the
project will be advertised within the next couple of weeks.
B. Adaptive Traffic Control Signal System — RFP — AE/Malpica — Staff is
reviewing and completing the RFP and the project will be advertised in the next
couple of weeks.
C. Copley Drive/Golden Springs Drive Intersection Enhancements —
AE/Malpica — Contract approval has been moved to the February 20th City
Council meeting due to changes to the staff report.
Chair/Mehta asked staff to discuss the changes at the intersection.
AE/Malpica reported that during the morning hours, there are many westbound
left turns from the Golden Springs Drive onto southbound Copley Drive.
Currently, drivers can make a left turn on a green arrow and green ball
(protective/permissive). The signal will be modified to be a "protective" only
signal. In addition, there will be ramp modifications, video detection cameras
to enhance detection, a new CCTV camera to monitor real time traffic and
timing modification to accommodate traffic volumes coming into the westbound
left -turn pocket. There will also be some minor restriping, modifications to the
median on the west side of the intersection, and replacement of current signs
with up-to-date signage including a "no -right turn on red" sign for northbound
vehicles. In general, the purpose of the scope of work is to change the signal
from "protective/permissive" to "protective" only.
D. City Entry Monument Sign Design Concepts —AE/Beshay— Final Plans and
Specifications are near completion with bid opening in early March and start of
construction in April.
February 8, 2018 PAGE 4 T&T COMMISSION
E. Pathfinder Road Rehabilitation (LA County) — AE/Beshay — This project is
being managed by L.A. County. He provided a map of the area and pointed
out the location the project encompasses. The area will be cold milled and
resurfaced with AC pavement. The estimated start date within the City of
Diamond Bar is set for the end of February, with completion slated for early
April.
Chair/Mehta asked about benefits of this project. AE/Beshay explained that it
is a grind and overlay which means brand new pavement surfacing.
F. Citywide Drainage Improvement Project — Phase I and Phase II —
AE/Beshay — This project has three locations: A) Golden Springs Drive, west
of Platina Drive, B) Brea Canyon Road north of Sapphire Canyon Road, and
C) Hipass Drive at Castle Rock Road. This project is to improve the
groundwater conditions at these three locations. Plans and Specifications are
near completion with bid opening in early March and construction beginning in
April
C/Garg asked for more detail regarding Phase 1 and Phase Il. AE/Beshay
responded that there are two locations in Phase 1 (A&B) and one location (C)
in Phase 11.
G. Lemon Avenue Interchange Project— SCENoung —Beginning this weekend
(tomorrow at 10:00 p.m.) there will be a series of closures that will be taking
place over the next few weekends. The closures will consist of the number 3
and 4 lanes along the SR -60 in either the eastbound or westbound direction
depending on the weekend. In addition, there will be some ramp closures to
pave the westbound and eastbound ramps at Lemon Avenue. Starting Friday,
February 9th, along the westbound direction of the SR -60 between Brea
Canyon Road and Fairway Drive, the number 3 and 4 lanes (two lanes on the
right side) will be closed continuously until 5:00 a.m. on Monday, February
12th. In addition to the lanes being closed, the Brea Canyon Road westbound
on-ramp will be closed so that concrete trucks can be staged on the on-ramp
in order to pave the new westbound on-ramp at Lemon Avenue. Traffic
modeling has projected that traffic may back up, up to 10 miles along the SR -
60. Therefore, Diamond Bar may experience heavy congestion on the City
roadways during this time. While the notice ACE released identifies detours,
there will not be signed detour routes within Diamond Bar, which means that
traffic will have to find its own way through the streets should drivers choose to
exit the freeway. The good news is that the Traffic Response System is in
place to automatically adjust signal timing along the major corridors of the City
(Golden Springs Drive, Grand Avenue and Diamond Bar Boulevard) should the
threshold volumes be met. In addition to the Traffic Responsive System, staff
and the City's engineering consultant, who lives locally, will be monitoring
traffic throughout the weekend during the closure. There are no closures next
weekend due to the Presidents' Day holiday. The closures will resume the
weekend of February 23rd and will consist of the following: The number 3 and
February 8, 2018 PAGE 5 T&T COMMISSION
4 lanes will be closed along the SR -60 in the eastbound direction and the
Fairway Drive eastbound on-ramp in unincorporated L.A. County/Rowland
Heights will be closed. The following weekend of March 2"d, the eastbound 3
and 4 lanes will be closed as well as the eastbound Brea Canyon Road off
ramp. If there is a need to continue paving the new eastbound on-ramp at
Lemon Avenue, there will be a closure on the weekend of March 9th as well.
Because the Brea Canyon Road on-ramp will be closed, the signal at
westbound Brea Canyon Road on and off -ramps will be on red -flash for the
weekend beginning Friday, February 9th at 10:00 p.m. The intent of these
closures is to get the ramps paved and the plan is to open the new westbound
on-ramp and eastbound off -ramp along Lemon Avenue sometime in March.
Once the eastbound Brea Canyon Road ramps are closed, there will need to
be additional signal timing modifications for the ramp signal along Golden
Springs Drive and the eastbound ramps, as well as construction of sidewalks
and curb and gutter. The project is on schedule to be completed by this
summer.
H. SR57/60 Confluence Project — SCENoung — Construction continues. The
westbound on-ramp at Grand Avenue remains closed. Originally, it was
projected to be opened in February; however, the contractor now estimates
that it will not open until mid-March. Similarly, the westbound off -ramp right -
turn -only restriction at Grand Avenue will stay in place until mid-March. The
new westbound slip ramp along Grand Avenue that is under construction is still
on track to be opened by the end of the calendar year, which has been
delayed due to SC Edison poles that are currently in the ramp location. The
poles need to be relocated out of the construction area.
I. Grand Avenue/Golden Springs Intersection Improvements Update —
SCENoung — This project is still in design phase for the landscape
improvements. Staff asked the consultant to include steel panels and accent
lighting in the medians. As a result, the consultant sent the plans out to an
electrical engineer for design. Once completed, the design can be finalized
and sent to the City of Industry, since it is their project that is taking place
within Diamond Bar's jurisdiction. Industry intends to have the project go out
to bid and be under construction sometime this summer.
J. Morning Canyon Road Rehabilitation Project — SCE/Young — Staff
continues to work with the contractor to get the final road repair underway.
She has asked that the contractor complete this project by February 22nd
Once the repair plan is submitted and approved, the contractor will make the
repairs as ordered so that the project can be finalized and closed.
K. TR 63623 — Southpointe Residential Development/Larkstone Park —
AE/Aoun — The residential development has opened six of the 10 phases for
residents to move in, and the developer is currently working on construction of
phases 7, 8 and 9. For Larkstone Park, the contractor is completing the punch
list items which should be finished this month, allowing for further plan check
and opening of the park by the middle of this year.
February 8, 2018 PAGE 6 T&T COMMISSION
L. Diamond Bar Ranch Shopping Center (Sprouts) — Development Update
AE/Aoun—Construction continues. The Habit recently resubmitted plans and
is moving forward with plan check. There is no current estimated date for
construction. McDonald's is moving forward quickly with the building under
construction and grand opening planned by April. Sprouts, Chipotle, and
Coffee Bean & Tea Leaf are opened. There is not yet a potential opening date
for Ross.
M. Diamond Bar Strategic Plan Mid -Year Update — PWD/Liu — Staff provides
an update of the City's Strategic Plan to the City Council on a quarterly basis.
The current update is a mid -year update for the period from July 2017 to
December 2017. Copies were provided to each Commissioner. The update is
provided in table form that includes a total of 79 action items. The vision that
was created for this strategic plan is "Celebrating our roots, Building a thriving
future". Under this vision are three overarching goals: 1) Responsible
stewardship of public resources, 2) Open, engaged and responsive
government, and 3) Safe, sustainable, healthy community. Under each of
these goals are the corresponding action items. For the current Fiscal Year
2017-18, out of the 35 action items listed for this year, 10 have been
completed, 24 are in progress and 1 item has not yet been started. For year
two of this plan, there are a total of 24 items, and of those 24, 3 have been
completed, 17 are underway and 4 have not yet been started. For year 3,
Fiscal Year 2019-20, there are a total of 20 items, one of which has been
completed, 15 are underway and 4 are not yet started. These action items
sum up the commitment of the City to continue providing services that the
residents and businesses expect.
Under the goal of Safe, Sustainable and Healthy Community, progress
continues on the SR -57/60 Confluence Project, as well as the Lemon Avenue
Project. PWD/Liu pointed out other projects that are underway that are listed
under the umbrella of Safe, Sustainable and Healthy Community. Staff will
continue to provide the Commission with monthly updates on the projects that
are in process. This three-year plan is a working document and staff
continues to provide updates and status to the Commission and the City
Council moving forward.
Chair/Mehta asked the status of the missing SR -57/60 connector. PWD/Liu
responded that as of June 2017, the Supplemental Needs Study has been
completed, which is a cost -benefit analysis. Diamond Bar is working to
convince the state to make some local improvements at the Diamond Bar
Boulevard on and off ramp locations within the next two to three years. Staff
believes this would increase capacity to a certain extent. Second is to
convince the state to conduct a more detailed engineering study such as a
Project Study Report for the missing components. Moving forward, Diamond
Bar is doing everything possible as a City while making sure that Caltrans and
Metro are aware this should be on their action plan.
