as submitted. Motion carried by the following Roll Call vote:
AYES: COMMISSIONERS: House, Mahlke, Mok, Chair/Pincher
NOES: COMMISSIONERS: None
ABSENT: COMMISSIONERS: VC/Carrera
II. PUBLIC COMMENTS: Frank Chang asked if bike striped lanes could be added
from the SR -60 to Longview Drive on south and northbound Grand Avenue. SE/Yee
had previously responded to Mr. Chang via e-mail that, after previous consideration of
this matter, the City's Traffic Engineer decided not to add these bike lanes. Mr.
Chang asked the Commission to request another evaluation of the situation due to
increased bike traffic. He also requested speed bumps on Summitridge Drive and he
was told by staff that he needed to collect 50 signatures in order for the City to
consider the request. Mr. Chang felt this to be unreasonable.
FEBRUARY 16, 2012 PAGE 2 T&T COMMISSION
SE/Yee responded to the speaker's comments.. He confirmed that he responded to
the speaker's e-mail regarding his request for a Class II bike lane (a striped lane).
This request was considered in 2008 when the City's Traffic Engineer conducted a
study to determine whether Class II bike lanes would be appropriate to install on
Grand Avenue. As a result of the study, and staff's research involving design
guidelines for bike lanes on arterial roadways including examining slope conditions on
Grand Avenue, the Traffic Engineer's recommendation was to not install Class II
striped bike lanes on the street. This was due to studies indicating that when striping
is installed, it gives a false sense of security for bikers who are less experienced.
Under the current conditions, there is signage that allows for biking on Grand Avenue.
As a result of the Engineer's study and in regard to the design guidelines, staff felt it
was best to follow the Traffic Engineer's recommendation to not install any type of
permanent striping on Grand Avenue.
PWD/Liu added that, with respect to the speaker's request to have "speed bumps"
installed on Summitridge Drive, the City has a very successful Neighborhood Traffic
Management Program (NTMP) and staff will be happy to work with the residents
along Summitridge Drive to determine whether the residents want to pursue traffic
calming devices installed. As everyone knows, when traffic calming devices are
installed, it impacts the residents along the street as well. Collaboration of residents
is needed and staff will provide the speaker and residents with the necessary
information.
Mr. Chang requested to speak again. He questioned what kind of false impression
bike lanes would create with respect to bikers feeling protected within the bike lanes.
SE/Yee explained his understanding of the reason the City has Class II bike lanes on
Diamond Bar Boulevard and Golden Springs Drive. The grades on Grand Avenue
are higher than the grades on Diamond Bar Boulevard and Golden Springs Drive and
because of that fact, there are concerns about bikers picking up unsafe speeds —
especially inexperienced bikers.
Mr. Chang again took exception with staff's explanation and decision. SENee offered
to discuss this matter with Mr. Chang at a future time.
ITEMS FROM STAFF:
A. Received and Filed Traffic Enforcement Updates for:
Citations: November, December 2011 and January 2012
Collisions: November, December 2011 and January 2012
Street Sweeping: November, December 2011 and January 2012
IV. OLD BUSINESS: None
FEBRUARY 16, 2012 PAGE 3
V. NEW BUSINESS:
A. Diamond Canyon Road On -Street Parking
T&T COMMISSION
SENee presented staff's report which included seven written responses. Four
of the responses were from carpoolers who park on the street and asked that
staff retain the parking. Letters were received from the following persons who
spoke in favor of keeping the current parking: James Inouye, Rowland
Heights; Chris Floursch, Chino Hills; Thomas Chen from Diamond Bar. Three
responses against the current parking were received from Brian S.Sim, Qimei
Tang, and one from Evelyn Chu of Diamond Bar. A petition was also
submitted that included the signatures of 45 residents. Staff recommends
that the Traffic and Transportation Commission receive public comments.
Peter Valter, 3503 S. Oak Valley Place, spoke against parking on Diamond
Canyon Road based on safety issues. He said he did not receive a written
notice from the City about this matter and, therefore, did not have an
opportunity to respond in writing.
Eric Chang, 20608 E. Oak Meadow Lane, spoke against parking on Diamond
Canyon Road based on safety issues. There are no sidewalks and people
have to walk in traffic lanes.
Jill Chang, 20608 E. Oak Meadow Lane, speaking for herself and on behalf of
Qiang Ni, 20602 E. Oak Meadow Lane, spoke against parking on Diamond
Canyon Road due to safety concerns for service vehicles and children.
Marlene Seng, 3503 S. Oak Valley Place, spoke against parking on Diamond
Canyon Road stating her main concern is for pedestrians. Most days there are
20-24 cars parked on the street. There are no sidewalks and also, people
throw their trash in the street. She also believed it was close to impossible for
the Sheriff's Department to respond to calls on the street in a timely fashion.
She said she did not sign the petition because she did not know about it.
Anna Ching, 3528 S. Diamond Canyon Road, spoke against parking on
Diamond Canyon Road stating her concern was u -turns, lack of accessibility
for service vehicles, double parking and trash in the neighborhood.
Victor Lee, 853 Pinefalls Avenue, Walnut said he understands the pain of the
residents. Because he is a carpooler, he needs a solution because there is
not enough room to park on Pathfinder Road. He does not dump trash and
tries to be respectful of the residents and he believes those who dump trash
should be penalized. No one should be permitted to park close to or at the
curve; however, along the street are safe parking areas. He understands that
people may be walking but because they do not have sidewalks, people
should not be walking in the area. He asked if the City could leave parking
spaces on the street. He also asked if it was possible to request use of church
parking.
FEBRUARY 16, 2012 PAGE 4 T&T COMMISSION
Jack Phone, 3502 S. Oak Valley Place, spoke against parking on the street
due to safety concerns and the amount of trash left on the streets.
PWD/Liu thanked residents for their comments before the Commission for
their consideration. Staff's goal is to continue soliciting comments until the
next Traffic and Transportation Commission meeting in March. At that time,
staff will offer its recommendation. The Park `n Ride lots in the City are owned
and maintained by the State of California (Caltrans); therefore, the City has no
jurisdiction over the lots. The City has little opportunity for input as to what
occurs at those lots. However, staff has observed that these lots are fully
maximized. The City streets are public streets and because the City is at the
crossroads of freeway intersections, individuals utilize this area more
frequently and on a regular basis to carpool. This presents a balancing act
opportunity for residents and the City. Staff hopes to come back to the
Commission with workable solutions.
B. Centerline Striping on Palomino Drive and EI Encino Drive.
AE/Malpica presented staff's report and recommended that the Traffic and
Transportation Commission receive public comments and concur with staff to
install approximately 50 feet of double yellow centerline striping.
Ben Mayorga, 23843 Palomino Drive, spoke against the centerline stripping.
He feels throughout the day there are different volumes of traffic and the issue
is not people crossing over the raised crosswalk; the issue is the speed drivers
are traveling. Some of the mitigation efforts have helped with the speeding, but
unfortunately, there is too much ground to cover for cars to slow down and
drivers use the crosswalk as a launching pad. In his opinion, centerline
striping will do nothing to mitigate the problem of speeding cars. He suggested
installing a stop sign instead.
SENee stated that as part of this analysis, the City's Traffic Engineer
conducted a stop sign warrant analysis for this location and visited the location
during peak hours when children are being dropped off, picked up and when
they are walking home from school. Based on the analysis, the stop sign was
not warranted. Stop signs are not meant to be used for traffic calming; they
are meant to be used for traffic control purposes. When stop signs are placed
in locations where they are not warranted, driver behavior would change. For
example, drivers would feel that they would lose time by having to stop at
Palomino Drive and EI Encino Drive so they would speed up on the approach
or on the departure. A stop sign was considered; however, for this reason, it
was found to be not warranted for this location.
C/Mahlke responded to the speaker that the City has no control over school
parking issues. The City has been advised about what the school is doing but
it is not the City's property and we therefore do not have a say in the matter.
However, she imagined that once the new traffic pattern is implemented at
Golden Springs School, the City would then re-evaluate the issue.
FEBRUARY 16, 2012 PAGE 5 T&T COMMISSION
AE/Malpica explained that the recommendation was an incremental approach
which would allow staff to further monitor the traffic patterns.
C/House moved, C/Mahlke seconded, to approve staff's recommendation to
install approximately 50 feet of double yellow centerline striping on Palomino
Drive and EI Encino Drive. Motion carried by the following Roll Call vote:
AYES: COMMISSIONERS: House, Mahlke, Mok, Chair/Pincher
NOES: COMMISSIONERS: None
ABSENT: COMMISSIONERS: VC/Carrera
C. Centerline Striping on Evergreen Springs Drive at Harmony Hill Drive
AE/Malpica presented staff's report and recommended that the Traffic and
Transportation Commission receive public comments on this matter.
C/House stated that there has recently been red curb painting installed at the
location. He observed the crossing guard experiencing problems with cars
parking at the red curb locations and behind cones that were placed to block
parking. Drivers do not obey these traffic barriers and should be cited by law
enforcement. Striping or additional red curb painting will not solve this
problem. The Sheriff's Department needs to provide enforcement in the area.
AE/Malpica responded that he and law enforcement have been to the site
many times and the moment drivers see law enforcement presence, they start
behaving. The deputy has written a couple of tickets and people complain
about receiving tickets when others are not cited. The proposed striping
improvements would open up the corner which would make it easier for drivers
to see oncoming cars.
C/House stated there is already a red curb. He believes the Sheriff's
Department needs to put more time into working these hot spots. The City
needs to stop people from parking in the red zones and no -stopping zones and
the City needs to change the behavior of drivers, not just with signs and
striping. AE/Malpica responded that staff has asked the school to remind the
parents that they should not park at a red curb and that they should not double
park.
Chair/Pincher asked if the striping beyond Harmony Hill Drive down on
Evergreen Springs Drive where the street turns into Castle Rock Road would
be repainted at the same time. She stated the yellow paint is pretty faded.
AE/Malpica said he believed this location was included in the maintenance
schedule together with all of the other area striping. He did not have specific
information about when it was scheduled to be repainted.
C/Mok asked if the restriping would impact any of the nearby residences.
AE/Malpica said he did not believe it would, since no residents currently park
in that area.
FEBRUARY 16, 2012 PAGE 6 T&T COMMISSION
C/House moved, C/Mok seconded, to approve centerline striping and add 55'
of red curb on Evergreen Springs Drive at Harmony Hill Drive. Motion carried
by the following Roll Call vote:
AYES: COMMISSIONERS: House, Mahlke; Mok, Chair/Pincher
NOES: COMMISSIONERS: None
ABSENT: COMMISSIONERS: VC/Carrera
D. Evergreen Springs Drive Lane Striping
SE/Yee presented staff's report and recommended that the Traffic and
Transportation Commission receive public comments and concur with staff to
install the proposed lane striping and red curb.
C/Mok asked if the striping included the wide striping letting traffic know that in
the left lane, drivers can either move forward across Pathfinder Road or make
a left turn, and that the right lane is strictly a right turn lane. He also asked if
there will be signage that indicates "right turn only." SE/Yee responded that all
of C/Mok's statements are correct. Legends will be painted on the pavement
and there will be signage to compliment that legend as well. C/Mok asked if
staff had any comment from the resident who lives on the corner about
painting the curb red. SE/Yee responded that the City notified the resident and
did not receive a response.
C/House moved, C/Mahlke seconded, to concur with staffs recommendation
to install lane striping and red curbing on Evergreen Springs Drive at
Pathfinder Road. Motion carried by the following Roll Call vote:

VIII. INFORMATIONAL ITEMS:
A. Traffic Signal Battery Backup System Project—AE/Malpica stated that staff
has completed testing of all of the units and conducted a project walk on
February 2"d. During the field inspection, staff noticed that a couple of units
were faulty. Staff is working with the contractor and vendor to resolve these
FEBRUARY 16, 2012 PAGE 7 T&T COMMISSION
issues. Initially, staff felt some of the intersections needed to be upgraded with
LED's which are more energy efficient. As a result, the contractor is currently
upgrading those intersections. Once the upgrades are completed, staff will
schedule a final project walk to make certain that the upgrades were correctly
completed. The final punch -list will be done two weeks after the final project
walk and a Notice of Completion will be filed in March. Once the current
project is finalized, 11 locations will be added and the same process will be
followed.
B. Tin Drive and Bridle Drive Striping Improvement—AE/Malpica reported that
the City installed the four -inch channelized line and staff continues to monitor
the site. Staff has not received any complaints and is assuming that the
striping is doing what it was intended to do. Staff will continue to monitor the
striping and make certain it is well-maintained.
C. Median Modification — Diamond Bar Boulevard/Clear Creek Canyon Drive
— AE/Malpica stated that a pre -construction meeting was held on Monday to
discuss with the contractor how this project should be approached, since
construction was scheduled to happen on a main arterial. Construction start
date is set for February 27th. The contractor will engage message boards to
inform residents and other motorists when construction will begin and that the
left turn lane will eventually close. When the lane closes, the contractor will
provide detour signage. Residents in the area have an option to use
Rapidview Drive, which turns into Clear Creek Canyon Drive. Construction is
anticipated to take 30 -days or less.
D. Silver Fir Road and Windwood Drive Stop Sign —AE/Malpica reported that
the stop sign legend was installed on January 25th. Staff has received no
comments and continues to monitor the site.
E. "The Rock" Move — SE/Yee reported that there has been significant progress
since staff's last update to the Commission. The hauling company notified
staff that they now have a target date of March 2nd and 3'a for moving. This
move will occur in the middle of the night between those two dates, with
temporary lane closures on Chino Avenue, Chino Hills Parkway, Grand
Avenue, Diamond Bar Boulevard and Pathfinder Road. The hauler will be
accompanied by a fleet of CHP vehicles and notifications to affected
businesses will be out at least 72 hours prior to the move. In addition,
notification boards will be posted along the route three days prior to the move.
Chair/Pincher asked if there would be restricted parking on Pathfinder Road
during the move. SE/Yee responded affirmatively.
C/Mok asked how many lanes the hauler would occupy during the move and
about how much time the hauler would spend on DB streets. SE/Yee
responded two lanes for the transport vehicle and time is estimated to be
about six or seven hours beginning at 11:00 p.m. or midnight on March 2nd and
be out of DB by about 6:30 a.m. on March P. PDW/Liu explained that the
FEBRUARY 16, 2012 PAGE 8 T&T COMMISSION
vehicle travels at about 2-3 mph. C/Mok asked if any traffic would be allowed
to pass the vehicle and CHP. SE/Yee responded that most likely, only
emergency vehicles would be permitted to go around the transport vehicle(s).
All other vehicles will be detoured to other routes. Message boards and the
CHP will advise and monitor all vehicles.
C/Mahlke said she would like to witness the transport and asked if anyone has
been tasked with documenting this historical event for the City. SE/Yee said
staff believes that either National Geographic or Discovery Channel will
complete a video of the move. He said he would personally be present
because he is concerned with the move and is sure there will be video footage
to capture the event.
F. U.S. Post Office Parking Lot (Diamond Bar Boulevard/Montefino Avenue)
— SE/Yee reported that staff met with the branch manager to discuss
circulation issues. He explained that changes were made due to a significant
amount of cut -through traffic coming through Montefino Avenue and cutting
through the post office drive to get to the Albertson's shopping center. The
post office is Federal property and the City has no leverage to suggest
particular changes; however, staff did suggest that they install more permanent
regulatory type signage to replace the homemade signs currently in place.
SE/Yee drove by the site today and discovered that proper signage had been
installed for the "do not enter" portion of the driveway.
G. Lemon Avenue On/Off-Ramps Project — AE/Young explained that she has
no additional information to report at this time. The E76 is still with Caltrans
Headquarters and until staff receives further word from Caltrans staff, the
project is at a standstill with respect to moving forward with the right-of-way
phase. She received a call from a resident who received notice from Caltrans
about the upcoming property appraisal, indicating that the notice phase is
moving forward.
H. Residential Area 1(a)/Arterial Zone 6 Road Maintenance Project —
AE/Young reported that design is currently under way by Onward Engineering
and is expected to be completed by the end of March. The City will go out to
bid shortly thereafter with a scheduled bid opening at the end of April.
Assuming that the low bid comes in responsive and City Council awards the
contract, staff anticipates construction will commence the beginning of June.
CDBG Curb Ramp Project (FY 2011-2012)—AE/Young stated that bids were
opened yesterday. Nine bids were received and the apparent low bidder was
Gentry Brothers with a bid of $165,500. The engineer's estimate for this
project was $195,000 for 82 curb ramps in the vicinity of Maple Hill Elementary
and Chaparral Middle Schools. The high bid was $268,000. The award of
contract for Gentry Brothers is expected to go to Council on February 21St. If
approved, construction will commence the beginning of March.
FEBRUARY 16, 2012 PAGE 9 T&T COMMISSION
J. Chino Hills Parkway/Chino Avenue Street Rehabilitation Project —
AE/Young indicated that this week staff received word that the City's right-of-
way certification was approved for this project and the E76 was sent to
Caltrans Headquarters. Staff hopes to have authorization in the next few
months and be able to go out to bid shortly thereafter.
K. Caltrans Slope Repair — Golden Springs Drive — AE/Young reported that
staff met with the contractor and Caltrans inspector. All construction for this
project is anticipated to be completed by next Wednesday. The anchors are
installed, the netting along the face of the slope has been installed, and the
next steps are to repair some broken sidewalk and hydro seed the slope which
is expected to be done next week.
L. SCAG East-West Freight Corridor Proposal — PWD/Liu reported that this
week staff prepared and submitted written comments on the EIR for the draft
2012 RTP. SCAG staff continues to focus the truck lanes on the SR -60 and
the San Jose Creek as part of the east -west freight corridor between the SR -
710 and the SR -15 freeways. Staff raised a few issues: 1) staff believes it is
premature to identify these two alignments as a viable east -west freight
corridor when the EIR indicates that further studies are necessary; 2) DB also
believes SCAG has understated the environmental impacts by including three
segments of the east -west freight corridor in the financially constrained plan
and; 3) inaccurately assumed that all of the trucks that would be using this
corridor would produce zero emissions by the year 2035. DB's ongoing effort
is to request that SCAG continue considering all possible east -west routes in
order to meet the demands of the growing regional goods movement.
However, it appears that DB's ongoing efforts have proven futile because
when he attended this afternoon's meeting of COG's Transportation
Committee meeting, they voted "yes" on SCAG's proposal. DB was the Ione
negative vote. While the process is not over, SCAG will continue to receive
public comment and the 2012 RTP will go before the Regional Council of
SCAG in early April, at which time SCAG will take formal action to adopt the
RTP.
On another note, SE/Yee referred to a letter received by staff from PUSD. A
copy was distributed to the Commissioners before tonight's meeting. This was
in regard to memorializing the items and status of the new parking/drop
off/playground construction project and status of last meetings updates to the
Commission.

FROM: Rick Yee, Senior Civil Engineer
SUBJECT: DIAMOND CANYON ROAD ON STREET PARKING
RECOMMENDATION
Background/Discussion:
At the February 2012 Traffic and Transportation Commission Meeting, residents and
other affected persons were invited to present their concerns related to proposed
parking restrictions on Diamond Canyon Road. This item originated because of a
petition that was signed by homeowners in the Diamond Canyon Community requesting
elimination of all on street parking due to concerns with double parking and unsafe u-
turns.
Based on resident input and comments from those who park along Diamond Canyon
Road, it was learned that several of the parked vehicles are carpoolers (several of
whom are Diamond Bar'residents) that are unable to park at designated Park n Ride
facilities in the area. After evaluating the site, consulting with our traffic engineering
consultant, and considering both written and oral comments, staff recommends
installation of parking restrictions on the curved portion of Diamond Canyon Road. This
installation would include approximately 600 feet of red curb as shown in the attached
exhibit. In order to eliminate the double parking and u -turn movements in areas where
the line of sight for oncoming traffic is obscured, it is necessary to restrict parking on the
curved portion of the road. Street parking would still be permissible along the straight
segment of Diamond Canyon Road.
A notice (see attached) regarding the intent of the Traffic and Transportation
Commission to consider approval of this recommendation was sent to Diamond Canyon
Christian Church, Biosense Webster, and all residents in the Diamond Canyon
Community. Notices were also placed on the vehicles parked along Diamond Canyon
Road.
If approved by the Traffic Commission, the proposed improvements will be brought
forward to the City Council for their approval at the next regularly scheduled meeting.
Recommendation: It is recommended that the Traffic and Transportation Commission
concur with staff and approve the proposed red curb installation on Diamond Canyon
Road.

Dear Diamond Bar Resident:
SUBJECT: Diamond Canyon Road On -Street Parking
At the City's most recent Traffic and Transportation Commission Meeting on
February 12th, residents and other affected persons were invited to present their
concerns related to proposed parking restrictions on Diamond Canyon Road. This
item originated because of a petition that was signed by homeowners in the
Diamond Canyon Community requesting elimination of all on street parking due to
concerns with double parking and unsafe u -turns.
Based on resident input and comments from those who park along Diamond
Canyon Road, it was learned that several of the parked vehicles are carpoolers
(several of whom are Diamond Bar residents) that are unable to park at designated
Park n Ride facilities in the area. After evaluating the site, consulting with our traffic
engineering consultant, and considering both written and oral comments, the City's
Public Works Department is recommending parking restrictions on the curved

600 feet of red curb as shown in the attached exhibit. In order to eliminate the
double parking and u -turn movements in areas where the line of sight for oncoming
traffic is obscured, it is necessary to restrict parking on the curved portion of the
road. Street parking would still be permissible along the straight segment of

The City's Traffic and Transportation Commission will be considering approval of
this proposed parking restriction on Thursday. March 8th, at Diamond Bar City
Hall, Windmill Community Room, 21810 Copley Drive, Diamond Bar, at 7:00

Dear Diamond Bar Resident:
SUBJECT: Diamond Canyon Road On -Street Parking
At the City's most recent Traffic and Transportation Commission Meeting on
February 12th, residents and other affected persons were invited to present their
concerns related to proposed parking restrictions on Diamond Canyon Road. This
item originated because of a petition that was signed by homeowners in the
Diamond Canyon Community requesting elimination of all on street parking due to
concerns with double parking and unsafe u -turns.
Based on resident input and comments from those who park along Diamond
Canyon Road, it was learned that several of the parked vehicles are carpoolers
(several of whom are Diamond Bar residents) that are unable to park at designated
Park n Ride facilities in the area. After, evaluating the site, consulting with our traffic
engineering consultant, and considering both written and oral comments, the City's
Public Works Department is recommending parking restrictions on .the curved
portion of Diamond Canyon Road. This installation would include approximately
600 feet of red curb as shown in the attached exhibit. In order to eliminate the
double parking and u -turn movements in areas where the line of sight for oncoming
traffic is obscured, it is necessary to restrict parking on the curved portion of -the
road. Street parking would still be permissible along the straight segment of
Diamond Canyon Road.
The City's Traffic and Transportation Commission will be considering approval of
this proposed parking restriction on Thursday. March 8th, at Diamond Bar City
Hall, Windmill Community Room, 21810 Copley Drive, Diamond Bar, at 7:00
P.M.

Dear Sir/Madam:
Concerning the letter sent to Diamond Bar Residents informing us of the city's considerations to
amend the parking situation along Diamond Canyon Rd., I am very pleased and grateful to hear
the city is recommending parking restrictions on the curved portion of Diamond Canyon Road. I
am, however, very disappointed to learn the Public Works Department of Diamond Canyon City
has decided it safe to permit carpoolers to still park along the straight segment of Diamond
Canyon Road.
I cannot stress enough that Diamond Canyon Road, the entire street, is the only major route—the
only major entrance and exit—that residents of Diamond Canyon Road, workers of Biosense
Webster, and parishioners of Diamond Canyon Christian Church (including the Diamond
Canyon preschool and kindergarten) have available to them to safely enter and exit the street.
When or if implemented, it is my strong belief that the city's decision to consider allowing
carpoolers to continue to park on Diamond Canyon Rd., even if it is only on the straight segment
of the street, will not stop or prevent the problems we have had to face for the past year. That is
to say, it will not eliminate the occurrence of carpoolers making unsafe U-turns and blocking
traffic when they double park to drop off and pick up passengers. The problem of trash along the
street is also something I see persisting, if say, carpoolers are allowed to continue parking on the
street.
Furthermore, and more importantly, in the event of a personal emergency situation ---a situation
in which fire engines, ambulances, or any other emergency personnel need quick access to enter
and exit the street to provide aid ---or in the case that there is a need for an evacuation of
residents, workers, or parishioners, or all three, it is vital that the street be clear of any heavy
traffic or problematic hold ups. If hypothetically an accident were to result from a carpooler
making an unsafe U-turn, this will no doubt impede the flow of traffic and may, unfortunately,
prove costly when time is of the essence.
I understand and appreciate that the city has made an effort to amend the parking situation,
striving to accommodate both residents and carpoolers--some of whom are residents themselves.
And I do sympathize with those residents who are unable to park at designated Park n Ride
facilities. However, as a resident of Diamond Bar who happens to live on Diamond Canyon Rd.,
I would greatly like for things to return to how they were more than years ago when no parking
was permitted on the street --along both curved and straight portions.
What I am still asking is that the city considers re -implementing the "No Parking" signs that
were once posted all along Diamond Canyon Rd. However, if in the case that this cannot be
done, then perhaps the city should then consider something as drastic as proposing a plan to
construct an alternate street/route for all to safely enter and exit without the worry of running into
any problems like the ones mentioned above. I make these requests for our safety, peace of mind,
and the longevity of the community.
Thank you for your time and patience. And thank you for providing a platform upon which to
voice my concerns.
Sincerely,
S Ching
A resident of the City of Diamond Bar
