OLD BUSINESS:
A. PANTERA DRIVE NEIGHBORHOOD TRAFFIC MANAGEMENT PROGRAM
(NTMP)
AE/Malpica updated the Commission on the Pantera Drive NTMP and provided
background to the attendees, as well as a Power Point presentation to explain
the proposed traffic calming devices recommended by staff.
VC/Gonzalez and AE/Malpica discussed peak times of speeding and whether
traffic had slowed down. VC/Gonzalez also asked about what occurs with
traffic when there are games at Pantera Park in progress. He stated when
visiting the area, he observed cars going much faster.
C/Wong asked
about
alternatives
to getting 67
percent of the residents to sign
the petition for
those
who do not
have on-line
access.
AE/Malpica explained that previously, the City had mailed letters and petitions
to affected resident; however, this was found to be an unsuccessful method for
getting people involved. Subsequently, the on-line petition has provided better
aInd positive feedback.
PWD/Liu stated that, in consideration of moving forward with the next steps of
collaboration with residents, staff will need to provide an updated letter to 154
households. This will give them the option of completing the enclosed survey
JANUARY 9, 2020 PAGE 4 T&T COMMISSION
or going on-line to the City's website to provide comments in order to arrive at
the 67 percent (103 households) approval.
C/Mehta
agreed with
the
concept of both
on-line access and a mailing to
residents
because he
felt
it would increase
response.
VC/Gonzalez asked if the City would try one of the traffic calming options or
install all of them at the same time. Center lines look like a good option for
slowing the traffic, he added.
PWD/Liu responded to VC/Gonzalez that based on staffs experience having
implemented many of these neighborhood programs, in order to do a
comprehensive job, it is most prudent to install everything at one time. The
data indicates people are speeding. If, however, residents respond that they
do not like to see a center line or edge lines, staff will make every attempt to
educate them to the fact that this it is the right approach to install everything at
the same time.
Chair/Garg asked for public comments.
Stephanie Lubian, 823 Rexford Court, asked if the City was also monitoring
those cars that run stop signs while assessing the speeders. She feels ninety
percent of the drivers who run the stop signs are not necessarily speeding.
Just two days ago, she was nearly hit when she was trying to turn onto Rexford
Court because the oncoming car did not stop at the stop sign.
AE/Malpica responded that staff will work closely with the Sheriffs Department
regarding this enforcement issue.
Donovan Martinez, 635 Pantera Drive (corner of Shady Place and Pantera
Drive) asked if there was any discussion about addressing this area through
this program (outside of the yellow boundary indicated on the map). Pantera
Drive is a downgrade, east from the school to Leyland Drive. Once drivers get
on the straight line of traffic just past Sentry Drive, drivers tend to increase their
speed. He asked if this area could also be considered for traffic calming
devices.
Cindee Ocon lives at 24309 Sentry Drive, a couple of houses away from
Pantera Drive, just above where the previous speaker lives. She also wanted
to know if that area had been considered from the stop sign at Bowcreek Drive
down to the stop sign at Armitos Place/Leyland Drive. It is a longer stretch and
there are no other stop signs to slow traffic. Ms. Ocon believes a stop sign at
Sentry Drive would help tremendously. She goes to the park often to walk, and
some weeknights there are a lot of people coming from outside the
neighborhood to use the basketball courts.
Chair/Garg said that it was not encouraging to him that only four residents
were present this evening out of 154 households. He asked the speakers to
JANUARY 9, 2020 PAGE 5 T&T COMMISSION
help get their neighbors to sign the petition so that staff could move torward
with the installation.
Cindee Ocon said she has not seen the petition and asked if it had been
circulated.
PWDlLiu responded that this has moved beyond the petition process. This
program was initiated last year when 154 households were invited to the
Commission meeting to discuss the proposal. Prior to that, staff worked with
the neighborhood captains to start talking with their neighbors, around April,
May 2019, about participating in the program. Residents who have been
involved were limited to the two streets and from the comments from folks
outside of the current study area, PWD/Liu suggested that this be done in a
phased approach. Currently, the 154 households have been working with staff
and have been engaged in the process and the City should move forward to
finish the process as initiated. Whether or not the City should expand beyond
the current parameters, he would consider approaching it as a second phase.
C/Wong asked if studies have shown that placing speed cushions strategically
tend to stop drivers from blowing through stop signs.
PWD/Liu responded there are many studies that show how traffic calming
measures work together with stop sign controlled intersections. However, stop
sign controlled intersections are regulated very differently.
Sam Ocon, 24309 Sentry Drive, said it appears the focus is on Pantera Drive.
He wondered a there was going to be another phase to this program because
traffic on Sentry Drive, between Pantera Drive and Claywood Drive, is being
used as a cut -through by speeding traffic.
PWnil iu explained how staff arrived at the highlighted area. 1) Staff wants to
have a clearly defined area to focus the studies on and 2) staff wants to make
sure that, even for residents who are not close to proposed improvements,
staff can identify who might be using that stretch of roadway. This is why the
area goes beyond the area in and around the school. It is very clear that
based on traffic counts along Pantera Drive, they exceed 1300 which indicates
to staff that it is a busy street. Based on his experience, PWD/Liu is reluctant
to classify traffic as cut -through, because the fact is that the people who are
using those streets may actually be residents. Also, for the most part, people
who use those streets are familiar with the neighborhood, which is why they
use that street. In this case, staff wants to quantify the problem because the
majority of those people are speeding, which is directly related to "safety"
ssues for residents, drivers, pedestrians and children. While he sees the need
to follow up with additional households and perhaps additional streets, the
focus has been to address the bulk of the problem, which is speeding along
Pantera Drive. The only effective way to deal with the speeding is with speed
cushions — not the stop signs, not the edge line, and not the centerline.

C/Mehta thanked PWD/Liu for explaining the process to the speakers from
Sentry Drive and stated the Commission appreciated their presence and
bringing these matters to the attention of the Commissioners and staff.
C/Mehta moved, C/Quan seconded, to concurwith staffs recommendation to
move forward by reaching out to the residents to sign the petition for the City to
move forward with conclusion of the design plans and implementation of the
traffic calming tools. Motion carried by the following Roll Call vote:
AYES: COMMISSIONERS: Mehta, Quan, Wong,
VC/Gonzalez, Chair/Garg
NOES: COMMISSIONERS: None
ABSENT: COMMISSIONERS: None
NEW BUSINESS: None.
STATUS OF PREVIOUS ACTION ITEMS:
AE/Malpica responded to concerns expressed by C/Mehta at the last Commission
meeting regarding the storage length and timing of the left turn lane being too short at
the north SR-57 at Diamond Bar Boulevard. ET/Delgado determined that the lane is
150 to 160 feet long; therefore, during the last few weeks, staff extended the green
light phase so that it is now consistent with the traffic signal crossing at Sunset
Crossing Road and Diamond Bar Boulevard. At times, the lane may become
congested; however, after the adjustments were made, the lane is cleared, most of
the time. C/Mehta said he noticed the change/improvement.
AE/Malpica indicated that in addition, staff added green time during peak hours
(school rush hour) to the left -turn pocket on Golden Springs Drive proceeding
eastbound at Diamond Bar Boulevard. The reason the lane is short is that there is a
direct conflict with the left -turn on Golden Springs Drive at Torito Lane. Staff
continues to monitor the intersection.
ITEMS FROM COMMISSIONERS:
C/Quan said that while visiting family in Claremont, as she exited the freeway, she
noticed a sign "red right turn yields to green U-turn" and wondered if that would be
possible to post in Diamond Bar, especially at the intersection of Grand Avenue and
Diamond Bar Boulevard.
PWD/Liu responded to C/Quan that Diamond Bar has several locations that indicate
"right turn must yield to U-turn", such as the one at the south end of Diamond Bar
Boulevard in the area of Evangelical Free Church. At other intersections, such as on
Grand Avenue at Longview Drive, there are signs that simply say "no right turn on red"
and on Copley Drive at Golden Springs Drive. PWD/Liu said he would work with staff
to consider C/QuanIs comments.
VIII. SCHEDULE OF FUTURE CITY EVENTS; As noted in the Agenda

letter will remind Commissioners to reach out to the Council Member who appointed
them, if they wish to continue to serve on our T&T Commission.
