II. PUBLIC COMMENTS:
Dr. Steven Christopher, Principal, and Keith Lovell, Facilities Manager, Mt. Calvary
Lutheran Church, offered his recommendation to the Commission regarding the
school's staff and parents concerns about trees that are proposed to be re -planted on
the public right-of-way on Golden Springs Drive (near the school's entry/exit
driveways). He provided three scenarios outlined in a detailed letter with exhibits
dated October 10t" which he verbalized to the Traffic and Transportation Commission,
Dr. Christopher indicated a best -case scenario that there be no plantings of any kind.
This would ensure the line -of -sight for drivers be preserved at the school entry/exit off
of Golden Springs Drive.
C/Quan asked if parents' park on the street or drive up to the campus and Dr.
Christopher responded that there is no street parking.
C/Mehta stated that he understood the concern about the trees and wondered if Dr.
Christopher felt safe making a left turn, even if there were no trees. Dr. Christopher
responded it is not safe, but better without the trees. 45 miles per hour in front of a
school entrance and exit seems to him to be extreme and generally, traffic travels at a
higher speed than what is posted.
C/Wong shared that, as a parent of children who attend Mt. Calvary, he can attest to
the difficulty of making right and left turns. The line -of -sight is of concern because
vehicles traveling eastbound on Golden Springs Drive travel at a high rate of speed.
Also, it becomes difficult to turn into and exit the school grounds.
VC/Gonzalez added that he can also attest to difficulty with line -of -sight issues. He
hoped there might be compromise to plant something other than pine trees.
AE/Aoun provided an update to the Commission regarding the City's responses to the
church/school stating that upon originally receiving this inquiry from the school
principal, he and another staff member visited the site and drove the area. He is
familiar with the turning movements at the school. Based on his observation, there
was an opportunity between the trees to see oncoming vehicles. That being the case,
perhaps it would not warrant full removal of the trees. Also, they observed four pine
trees previously at that location and all four were removed due to the health condition
of the trees and the cause of sidewalk damage. Subsequently, it was determined that
only three trees will be replaced. There was one pine tree that was on the curb face,
closest to the street, which would have created the most visual obstruction. That
particular tree is not proposed to be replaced with another tree. With his
observations, discussions with engineering staff and maintenance staff, it was
determined that replacing the pine trees in order to maintain the consistency along the
corridor would be the best action. However, with that said, if there is a desire to have
staff look further into the matter, staff could utilize consultant services and engineering
services for that purpose. With regard to speed of vehicles coming down the
roadway, and in lieu of not replacing any of the trees, the plan would have been to
plant the pine trees and to look further into any opportunities for signage to warn

T&T COMMISSION
oncoming drivers that there is a school zone ahead and that they should maintain
their speed. Whether or not there are trees, if vehicles are driving faster than the
allowed 45 mph on the roadway, it could potentially cause more time for drivers to
make a right turn. He is not aware that there is a permitted left turn out of the
driveway and that matter could be researched as well.
Chair/Garg asked for confirmation that the City will review this request again and
provide a determination. PWD/Liu responded that staff will make a formal assessment
of the line -of -sight issue pertaining to the replanting of the canary pine trees. As a
reminder, the City has worked hard to retain as many trees as possible and have a
consistent streetscape, which is the ultimate goal.

projects for Area 7, The City is on a seven-year cycle for road
maintenance. Area 7 is on the northeastern end of the City and
includes the neighborhood of Pantera Drive, where the current NTMP
program is being considered. This project will include rehabilitation of
all local and collector streets within Area 7 for slurry seal and some for
cape seal which require more rehabilitation and localized repairs.
Diamond Bar Boulevard's heavy rehabilitation will include grind and
overlay. This part of the project will begin mid -November and continue
through to the end of the month. The location on Diamond Bar
Boulevard is between Mountain Laurel Way and Clear Creek Canyon
Drive. Currently, the contractor is in Area 7 demolishing the curb ramps
to install new ADA compliant curb ramps, where required by law.

OCTOBER 10, 2019 PAGE 5 T&T COMMISSION
PWD/Liu indicated that, prior to tonight's meeting, the Commission was given the
latest request for information with respect to the Commission's consideration of
revising the commission meeting schedule. Four Commissioners, present at last
month's meeting, concurred with the option to change from meeting monthly to bi-
monthly (every other month). C/Quan, C/Mehta and VC/Gonzalez responded to staff
that they prefer Option A, beginning with the month of January (January, March, May,
July, September and November). Should the needs arise, a special meeting may be
scheduled. Chair/Garg stated he responded by email and C/Wong stated he prefers
Option A as well.
PWD/Liu reported that staff is preparing a staff report to present to the City Council.
This change requires an amendment to the Municipal Code Ordinance, which must be
approved by the City Council and will be introduced for a First Reading on November
5th. Subsequently, on November Igth, the City Council will have a Second Reading
and upon conclusion, if approved, the change will become effective 30 days
thereafter. Since the Commission historically adjourns during the month of
December, this would take effect in January 2020,
VI. ITEMS FROM COMMISSIONERS:
C/Mehta stated that many of the residents have complained to him that the median
shrubs on Grand Avenue at Shotgun Lane, are overgrown again and obscuring the
line -of -sight turning into the entrance of The Country Estates. AE/Malpica explained
that the City's Public Works Maintenance Division continues to work with the
landscape contractor to determine the best -case scenario; whether to continue
trimming the shrubs on a more regular basis; replace it with other landscaping; or
remove the shrubs altogether. In the meantime, staff will continue to trim the shrubs.
C/Quan thought it would be better if the shrubs are removed because Bougainvillea
grows fast. The City does a good job of trimming them, but they grow back quickly,
especially when the weather is warm.
Chair/Garg said that VC/Gonzalez brought up an item at the last meeting about the
area just off the intersection of Gold Rush Drive and Pantera Drive, where one of the
stop signs is obstructed by tree growth. He wanted to know if staff was working on
this issue.
PWD/Liu responded that the request was forwarded to the Maintenance
Superintendent, who is in charge of bundling and scheduling trimming work. Staffwill
follow up and report back to the Commission at the next meeting.
VII. SCHEDULE OF FUTURE CITY EVENTS: As noted in the Agenda
ADJOURNMENT: There being no further business to come before the Traffic and
Transportation Commission, Chair/Garg adjourned the meeting at 7:20 p.m.
