SCE/Young reported with respect to an observation from Chair/Mahlke regarding the
intersection of Carpio Drive and Golden Springs Drive. Staff investigated the traffic
data and the City's Traffic Engineer reviewed the site conditions and determined there
was no line of site issues for vehicles turning right from Carpio Drive onto Golden
Springs Drive. Staff will continue to monitor the intersection.
SCE/Young reported to C/Sulakhe regarding her inquiry concerning the intersection of
Cahill Place and Grand Avenue. Since C/Sulakhe mentioned her concern involved a
school bus stop, staff will look at that situation once school is again in session in
August/September. It would allow staff to have a clearer understanding of all of the
roadway characteristics and vehicular interaction. Once staff has completed its
investigation, there will be a report back to the Commission.
NEW BUSINESS: None
STATUS OF PREVIOUS ACTION ITEMS: None
VII. ITEMS FROM COMMISSIONERS:
C/Pechy provided a photograph of an area of concern which included barriers and a
very untidy hillside that is visible to all who travel on Diamond Bar Boulevard across
from the trail head to Sycamore Canyon Park. He asked for information so that he
could pass along to concerned citizens. SCE/Young responded that the address of
the property is 1007 Banner Ridge, which is a hillside erosion failure issue that
occurred in December 2010. The hillside eroded into the street which required
emergency services to provide mitigation. As a result, this matter was turned into a
code violation case since the owners failed to properly respond to the repair. The
Courts took over the case from the City and it now follows due process according to
the violation. During the past couple of months, a Receiver was appointed to the
property (a third party) to repair the damage; however, the geotechnical reports that
are required to be approved by the City in order for the Receiver to obtain permits for
the repair are under review. Staff is hopeful that within the next few months the
reports can be approved and permits for the repair can be issued. C/Pechy asked if
the repair involved cleanup of the debris. SCE/Young responded she would consult
with the City's Code Enforcement officer to see if he can work with the property owner
to clean up the visqueen; however, no one is allowed to touch the slope in terms of
grading without a City permit. SCE/Young further stated that the k -rails have been in
place since the erosion occurred and because the hillside has not been deemed
stable and actually failed once and impeded both lanes of street traffic, the k -rail will
remain in place to protect the public right-of-way.
JULY 10, 2014 PAGE 3 T&T COMMISSION
C/Sulakhe asked if staff has a geotechnical report that describes what happened.
SCE/Young responded that there is a geotechnical report available. These hillsides
are 1 '/z:1 which is a steeper hillside than what is currently permitted for construction.
In addition, gophers can cause instability in hillsides and overall poor property
maintenance is a large factor in hillside erosion issues. This particular property has
two v -ditches along the benches (specific drainage devices installed on hillsides) and
if those are not properly maintained, can also lead to erosion issues.
VC/Carrera stated that coming across Pathfinder Road and Peaceful Hills Road, the
traffic signal was not operating on Tuesday evening. He asked if there was a battery
backup system in place at that signal because he expected to see flashing red;
however, the signal was not operating. AE/Malpica responded that currently, there is
no battery backup system at that location. PWD/Liu stated that the City's ultimate
goal is to have battery backup systems at all signals.
VC/Carrera asked if the block walls along Diamond Bar Boulevard are City -owned or
private property walls. He commented that during the recent earthquake, several of
the walls were damaged. PWD/Liu indicated that staff is in the process of
investigating that matter upon receiving inquiries from the public. There are at least
three or four property owners (three private properties and one county owned parcel
at the flood control channel) who contacted the City about the repair work. Staff is
looking into ownership of these the walls as well as, where the wall is located; i.e. in
the public right-of-way or on the private property side.
VIII. INFORMATIONAL ITEMS:
A. Grand Avenue Beautification Project — SCE/YoungreportedthatattheJuly
1St City Council meeting, staff presented the final design plan for approval and
sign -off to complete final plans and specs for submission to Caltrans next
week. Their review is necessary since a portion of this project is being funded
with federal dollars. Staff is hoping to entice Caltrans to complete its review
within 30 days so that bids can be let for commencement of construction no
later than October. If construction does not begin by October, construction will
likely be postponed until the new calendar year so as not to impose on
businesses and residences during the holiday season.
B. 2014 Citywide Speed Zone Survey — AE/Malpica said that in order to
continue to legally enforce the speed limits Citywide, the California Vehicle
Code requires speed limits to be developed on the basis of traffic and
engineering speed zone studies. These are required to be updated every
seven years to ten years. In 2004, the City Council adopted a resolution for a
Citywide Speed Zone Study which will terminate in August 2014. The updated
study was presented to the City Council on June 17th and was approved for
first reading. The second reading occurred on July 1St. The Speed Zone
Study recommended the speed limits to remain unchanged based on the 85th
percentile except for certain locations including: Brea Canyon Road at
JULY 10, 2014 PAGE 4 T&T COMMISSION
Fountain Springs Road to Copper Canyon Drive recommended to be reduced
from 45 mph to 40 mph; Diamond Bar Boulevard at Mountain Laurel Way to
Grand Avenue to be reduced from 45 mph to 40 mph; Diamond Bar Boulevard
at Golden Springs Drive to the SR -60 eastbound ramp reduced from 40 mph
to 35 mph; Diamond Bar Boulevard at Highland Valley Road to Temple
Avenue reduced from 50 mph to 45 mph; Golden Springs Drive at Lemon
Avenue to 900' west of Gona Court increased from 40 mph to 45 mph;
Lycoming Street at Lemon Avenue to Brea Canyon Road reduced from 35
mph to 25 mph; Pathfinder Road at Brea Canyon Road/South Fernhollow
Drive to Diamond Bar Boulevard reduced from 45 mph to 40 mph; Via Sorella
at Brea Canyon Road to northerly terminus (Institute of Knowledge) to be
posted at 35 mph.
C/Mok asked if the signals would be recalibrated based on the new speed
limits. PWD/Liu responded that it will depend on driver behavior and roadway
conditions. In 2015, staff will be looking at the timing at all signalized
intersections along the major boulevards to consider the level of service and
the efficiency of timing. Staff believes that data can be compiled after the new
speed limit signs are in place and become effective on August 15t
C/Sulakhe asked how drivers will know about the new speed limits. PWD/Liu
responded that there will be a learning curve. In addition, staff will be working
with the Public Information Department to get information out via the City's
newsletters beginning in August along with the signs being replaced with the
new speed limit signs. C/Mok shared that typically, the Sheriff's Department
will work with the public by issuing warnings for a certain amount of time
before issuing citations.
VC/Carrera commented that the various speed limits on Diamond Bar
Boulevard appear to be somewhat confusing because it appears the same
traffic will be flowing through that area. PWD/Liu responded that when Speed
Limit Studies are performed, there are various criteria considered. As an
example, Diamond Bar Boulevard speed limits were determined within each
segment based on land uses, such as commercial/shopping centers, lane
width/geometrics, etc.
C. Traffic Signal Battery Backup Project—AE/Malpica reported thatthe Traffic
Development Services, Inc. construction contract for $131,138 was approved
by the City Council on June 17th. A pre -construction meeting is scheduled for
July 141h and construction for the 30 -day project to install battery back-up
systems at 14 additional locations is slated to commence the end of
July/beginning of August.
D. NTMP — Castle Rock Road/Crooked Creek Drive Neighborhood —
AE/Malpica stated that the $29,366 Carvajal Truck & Tractor, Inc. construction
contract was approved by the City Council on June 17th. The pre -construction
JULY 10, 2014 PAGE 5 T&T COMMISSION
meeting is scheduled for July 151h with construction to begin the end of
July/early August and be completed by the end of August/early September.
The contract includes speed cushions, speed limit signs, centerline striping
and parking striping.
E. Diamond Bar Boulevard and Kiowa Crest Median Modification Project -
AE/Mosley stated that the scope of work for this project is to modify the
northbound median along Diamond Bar Boulevard at Kiowa Crest Median for
the purpose of improving the line -of -sight. The pre -construction meeting with
CT&T, Inc. and other utility agencies is scheduled for July 15th. Once begun,
construction is scheduled to be completed within 30 working days.
F. Morning Canyon Rehabilitation Project — AE/Mosley indicated that the
scope of work includes rehabilitation of the roadway from Diamond Bar
Boulevard to Stone Pine as well as, removal of 16 pine trees that are uplifting
the pavement/curb and gutter. Staff anticipates letting bids on July 22nd and
move forward to award a contract by August 12th
VC/Carrera asked if root barriers will be installed with the new species of trees
and AE/Mosely responded affirmatively and said that he is working closely with
the Community Services staff to plant less invasive species.
G. Lemon Avenue Interchange Project— SCE/Young reported that the project
is still in the right-of-way acquisition phase. All appraisals have been
completed and all offers have been presented to the affected property owners
and minus those who have settled, negotiations continue with the remaining
property owners. Staff hopes to have the right-of-way completed by the end of
the calendar year.
H. Area 2/Zone 1 Road Maintenance Project — SCE/Young stated that this
project was started this week with concrete demolition for new curb ramps.
Concrete will be poured in the new ADA compliant curb ramps beginning
Monday, July 14th. Localized asphalt removal and replacement will also begin
next week with the streets that received edge grind and overlay. Next will be
the chip seal and slurry seal for completion. During the pre -construction
meeting, staff learned that the slurry seal contractor will not be able to
complete his portion of the project until after school begins so that work will
likely be scheduled for Saturdays to avoid conflict with school traffic. However,
a lot of the streets including Mountain Laurel will be completed before school
because these are grind and overlay streets.
Willow Heights — Diamond Bar Boulevard and Brea Canyon Road (Site D)-
SCE/Young reported that mass grading operations continue. She encouraged
Commissioners to drive by the site because the walls have all been
constructed and mass grading is expected to be completed within the next two
to three weeks which will significantly reduce the amount of construction noise
affected residences are experiencing. Next week the sewer tie-in will be
installed which will put the contractor out on Diamond Bar Boulevard and
JULY 10, 2014 PAGE 6 T&T COMMISSION
Cherrydale. All of the residents have been notified of the impending work
because their ingress and egress will be impacted but not shut off. The lanes
will be reduced to one during work hours only. Staff has received a number of
complaints from residents in the Cherrydale neighborhood with respect to
noise and construction dust. AQMD has been to the site several times and
found the site to be in complete compliance with all air and noise quality
regulations. The contractor has been working within the designated hours
which are stipulated by the City's Municipal Code of 7:00 a.m. to 7:00 p.m.
The contractor has worked a few Saturdays and will be working this coming
Saturday; however, as a courtesy to the residents, on Saturdays they do not
begin work until 8:00 a.m. even though the code permits a 7:00 a.m. start time.
Staff has investigated and addressed all complaints received.
IX. SCHEDULE OF FUTURE CITY EVENTS: As stated in the agenda.

Transportation Commission, Chair/Mahlke adjourned the meeting at 7:45 p.m.
