I. PUBLIC MEETING
A. Workshop #4: Neighborhood Traffic Study for the
Rolling Knoll Road/Country View Drive/Quail Summit
Drive Area.
Mr. Foust stated his firm received 170 completed survey
questionnaires from the neighborhood residents which
indicates Quail Summit Drive accommodates approximately 45
percent of the daily traffic leaving the neighborhood and
dropping off children at the school; Rolling Knoll Road
accounts for approximately 30 percent of the daily vehicle
count, and Country View Drive accounts for approximately 2
percent of the daily traffic flow. He indicated his firm
was able to verify the survey figures which were
representative of the actual traffic volume counts. The
total trips per day entering and exiting the neighborhood is
7,000, the majority of which are generated by the residents
entering and exiting the neighborhood and student dropoff
and pickup at the school. The cut -through traffic is
minimal. Prior to the turn restrictions along Grand Avenue,
the neighborhood did experience a significant amount of cut-

through traffic. He indicated that he agrees with the
residents that the traffic considerations involve the
traffic generated by the neighborhood and the school
traffic. Mr. Foust suggested that solutions to the traffic
problems involve such things as policy enforcement and use
of the radar trailer.
Mr. Foust reiterated his suggested traffic and speeding
issue mitigation measures might include additional stop
signs in designated areas (High Bluff Road at Quail Summit
Drive and Country View at Rolling Knoll Road); continued use
of the radar trailer; special street striping for
parking/bike lane/school loading and unloading in the school
area to narrow the street width perception; double
centerline striping on Quail Summit Drive in front of the
school; additional street markings to designate crosswalks
and 25 MPH speeds in the school area; and a warranted
traffic signal light on Diamond Bar Boulevard at Quail
Summit Drive.
Mr. Foust stated that while stop signs may tend to slow
traffic, he does not strongly advocate these installations
because it leads to the need for additional enforcement. He
indicated that with respect to residents' requests, he
recommended a one-way stop on Sand Ridge Road at Coyote
Springs Drive instead of a three way stop. He stated that
although the "Yield" sign on Deer Crossing Drive at Country
View Drive is adequate, he concurs that it should be
replaced by a stop sign. He recommended the Grand Avenue
Botts dots remain in place. He indicated he does not
believe the Botts dots create noise to residents of Country
View Drive. He stated he believes that residents may
experience an increased noise level due to the volume of
traffic on Grand Avenue.
Mr. Foust responded to C/Tamaya that double yellow
centerline striping incorporates approximately one foot of
space on the street and tends to make the street appear
narrower to the driver which tends to slow traffic. It
looks brighter and stays brighter longer than the skip
yellow line. In addition, it is unlawful to drive on the
opposite side of a double yellow line.
C/Tamaya asked if skip centerlines on residential streets
are effective in reducing speed. Mr. Foust responded that
the reduction in speed is approximately two to three miles j
per hour.

T&T Commission
DDPW/Liu responded to VC/Leonard that a solid yellow line is
used as an edge line and not as a center line.
VC/Leonard suggested that staff contact Quail Summit
Elementary School to ascertain the proposed remodeling
plans. DDPW/Liu stated staff will be soliciting further
input from the school and from the residents prior to
forwarding a recommendation to the City Council.
C/Nice stated he is concerned about eliminating street
parking for residents. He would like to see the bus zone
located more southerly on Quail Summit Drive.
Chair/Istik stated he would prefer to see larger front yard
setbacks and narrower residential streets. He indicated the
recommendation for a traffic signal on Diamond Bar Boulevard
at Quail Summit Drive is ironic since residents indicated
traffic volume is a problem. He further stated that "and"
should be corrected to "at" so that Paragraph 3 on Page 1
reads: "A petition was submitted to the City Council
requesting that Country View Drive at Grand Avenue be closed
to eliminate cut -through traffic". He cautioned that the
City should carefully consider future density of homes
because of increased traffic volumes and speeding. He
recommended that the City provide a jogged curb for a school
bus turnout. The parents could then use the street curb for
loading and unloading.
Linda Beltran, 23308 Quail Summit Drive, stated she is
concerned that the proposed mitigation measures would
significantly change the look of her street and create
additional difficulties for entering and exiting the
residences.
Don Lemly, 1387 Rolling Knoll, asked if vehicles are allowed
to back out of driveways across double yellow centerlines.
Mr. Foust responded that although it is unlawful to drive on
the wrong side of a double yellow centerline, it is
permissible for vehicles to cross the double yellow line.
Mr. Foust responded to Mrs. Beltran that the school parking
restriction, if adopted, would be in effect 30 minutes prior
to the commencement of school and 30 minutes following
school dismissal.
Chair/Istik stated the City could subsidize the school bus
program in an attempt to increase ridership. In addition,
August 1, 1996 Page 4 T&T Commission
the City could ask the school district if it would consider
reinitiating staggered hours. He further stated that
because of the in -progress citywide school study, he would
not be ready to vote on a recommendation for the school.
Mr. Foust stated the school is proposing a turnout
loading/unloading area and not proposing loading/unloading
on the sidewalk area. Chair/Istik responded that due to the
fact that the school does not incorporate staggered hours,
it is a certainty that parents will drop off and pickup
their children on the street sidewalk areas.
Chair/Istik opened public testimony.
Claudia Huff, 1641 Fire Hollow Drive, stated she favors
initiating less intrusive solutions and those that involve
the least cost to the City. If those solutions do not work,
move on to the next category. She recommended a stop sign
installations at Sand Ridge Road and Coyote Springs Drive,
Highbluff Drive at Quail Summit Drive, and Deer Crossing
Drive at Coyote Springs Drive to slow the traffic. She
asked the City to consider measures other than Botts dots on
Grand Avenue to mitigate the noise. She indicated she
favors a traffic signal on Diamond Bar Boulevard at Quail
Summit Drive. She further stated she does not favor double
yellow centerline striping, street signs and street painting
to mitigate the school problems. She favors discussion of
the traffic concerns between the residents and the school in
order to reach a compromise.
Jerry Hamilton, 1429 Copper Mountain Drive, stated he
believes the traffic study should respond to the resident's
concerns. He favors use of stop signs.
Jack Tanaka, 23805 Country View Drive, stated he had not
recommended removal of the Botts dots on Grand Avenue. He
asked if a portion of the dots could be removed to lessen
the noise.
DDPW/Liu responded to Mr. Tanaka and Chair/Intik that the
Botts dots installation was part of the Grand Avenue
improvement. The installation was completed in accordance
with State of California standards.
Chair/Istik asked Mr. Foust the feasibility of addressing
the use of thermal plastic in place of Botts dots. Mr.
Foust responded that thermal plastic is preferable to paint
August 1, 1996 Page 5 T&T Commission
and Botts dots. Chair/Istik asked that this option be
included in Mr. Foust's report to the City Council.
Audrey Hamilton, 1429 Copper Mountain Drive, asked why the
Grand Avenue Botts dots are placed so close together. Mr.
Foust reiterated the Botts dots placement on Grand Avenue is
in accordance with State standards. There are different
standards for freeways.
Hubert Wilson, 23649 Country View Drive, stated the
residents would prefer to preserve the character of the
neighborhood street rather than add striping and signage.
He indicated he has not seen enforcement in his neighborhood
recently. Absent enforcement, mitigation measures such as
stop sign and signage will be ineffective. He recommended
the City Council ask with the schools to accommodate the
change in traffic patterns rather than expect the residents
of Quail Summit Drive to incorporate street changes. The
school traffic should be taken off of the streets. Mr.
Foust's traffic study ignores the original concern regarding
noise pollution proposed by the Country View Drive
residents.
Audrey Hamilton suggested that because the school has a
large amount of property available that they install a
drive-through for parking, school buses and student drop off
and pickup.
Frank Beltran indicated he believes that prior to the City
Council voting on mitigation measures, the City should seek
cooperation from the Walnut School District to install a
secondary access to the property.
Don Lemley, 1387 Rolling Knoll Road, stated he is in favor
of initiating mitigation measures such as stop signs in
stages with minimal cost to the City. He agreed with
Chair/Istik that the widening of sidewalks should be
investigated. He further stated he is concerned that
installation of a traffic signal on Diamond Bar Boulevard at
Quail Summit Drive will increase the cut -through traffic in
the neighborhood.
Wanda Tanaka, 23805 Country View Drive, stated that a survey
of Country View Drive residents indicates they wish to
postpone the installation of speed humps on the street until
the noise study is completed.
August 1, 1996 Page 6 T&T Commission
Art Ragazzi, 1335 Rolling Knoll Road, stated he favors a
stop sign on Country View Drive because cars entering
Rolling Knoll Road constitute a traffic hazard to the
Rolling Knoll Road traffic which has the right-of-way.
Hubert Wilson recommended that based upon Mr. Foust's study,
the City Council ask the City of Chino Hills to reopen the
Environmental Impact Report and look at the Grand Avenue
traffic impact.
Chair/Istik stated Chino Hills wanted a road through Tonner
Canyon to relieve the Grand Avenue traffic congestion as a
result of additional homes. Chino Hills could discuss the
possibility of a road through Soquel Canyon or Carbon Canyon
with San Bernardino County.
Mr. Foust responded to Chair/Istik that according to his
traffic count, approximately 35,000 to 36,000 vehicles per
day cross the intersection of Grand Avenue and Diamond Bar
Boulevard.,
DDPW/Liu responded to Chair/Istik that although certain
issues may not be addressed by the Neighborhood Traffic
Study, the areas of concern addressed by the citizens will
be identified and included in the report to the City
Council.
Chair/Istik closed public testimony.
C/Tamaya made a motion, seconded by C/Virginkar, that the
Traffic and Transportation not endorse the recommendation
for double yellow centerline striping and white parking
striping. The motion was carried 5-0.
VC/Leonard made a motion, seconded by C/Tamaya, to recommend
installation of all -way stop signs at the following
intersections: Sand Ridge Road and Coyote Springs Drive;
Deer Crossing Drive and Country View Drive, and Highbluff
Drive and Quail Summit Drive, if warranted. The motion was
approved 4-1 with Chair/Istik voting no.
C/Nice made a motion, seconded by C/Tamaya to recommend
installation of a three-way stop sign on Country View Drive
at Rolling Knoll Road. The motion was approved 5-0. ^ry

C/Tamaya made a motion, seconded by VC/Leonard to make no
recommendation with respect to the school issue until the
August 1, 1996 Page 7 T&T commission
school/school district is involved with the pick-up/drop-off
issue. The motion was approved 5-0.
Mrs. Beltran responded to C/Tamaya that she objects to a
traffic signal on Diamond Bar Boulevard at Montefino Avenue.
However, because a signal will be installed at that
location, there will most likely be a need to install a
traffic light on Diamond Bar Boulevard at Quail Summit
Drive. Mr. Beltran indicated a traffic signal at Quail
Summit Drive and Diamond Bar Boulevard will help the
residents entering and exiting the neighborhood.
DDPW/Liu responded to VC/Leonard that redesign
recommendations will be made with respect to the shopping
center driveway at Diamond Bar Boulevard and Quail Summit
Drive which will involve negotiations and, ultimately,
cooperation of the property owner.
RECESS: Chair/Istik recessed the workshop at 9:22 p.m.
RECONVENE: Chair/Istik reconvened the workshop at 9:35 p.m.
C/Virginkar made a motion, seconded by C/Nice to postpone
consideration of a traffic signal at Quail Summit Drive and
Diamond Bar Boulevard for one year.
DDPW/Liu responded to Chair/Istik that a traffic signal has
been warranted for Diamond Bar Boulevard at Quail Summit
Drive. It is more cost effective to design both the
Montef ino Avenue/Diamond Bar Boulevard and Quail Summit
Drive/Diamond Bar Boulevard traffic light installations
simultaneously.
The motion failed 3-2 with the following Roll Call voter
AYES: COMMISSIONERS: Virginkar, Nice
NOES: COMMISSIONERS: Tamaya, VC/Leonard,
Chair/Istik
ABSTAIN: COMMISSIONERS: None
ABSENT: COMMISSIONERS: None
C/Tamaya made a motion, seconded by VC/Leonard, to concur
with the Neighborhood Traffic Study finding that a traffic
signal is warranted at the intersection of Diamond Bar
Boulevard and Quail Summit Drive, and to defer any further
action on the subject until staff provides the Traffic and
Transportation Commission with a design assessment of both
August 1, 1996 Page 8 T&T Commission
the Montefino Avenue and Quail Summit Drive traffic signals.
The motion was approved 4-1 with Chair/Istik voting no.
Chair/Istik stated his "no" vote is because he is concerned
about a potential increase in cut -through traffic as a
result of a traffic signal installation at Quail Summit
Drive and Diamond Bar Boulevard.
VC/Leonard made a motion, seconded by C/Nice to proceed with
the Neighborhood Traffic Study recommendation for a ladder
crosswalk marking at Winterwood Lane and Quail Summit Drive.
The motion was approved 5-0.
VC/Leonard made a motion, seconded by C/Virginkar, to
recommended that broken yellow centerline striping be
installed the entire length of Coyote Springs Drive. The
motion failed 3-2 with the following Roll Call vote:
AYES: COMMISSIONERS: VC/Leonard, C/Virginkar.
NOES: COMMISSIONERS: Nice, Tamaya, Chair/Istik
ABSTAIN: COMMISSIONERS: None
ABSENT: COMMISSIONERS: None
Chair/Istik reiterated that the Neighborhood Traffic Study
report to the City Council should include the discussions
regarding the Grand Avenue noise concerns.
Chair/Istik made a motion, seconded by VC/Leonard, to
recommend that the City Council consider conducting a Noise
Study to address the Country View Drive resident's concerns.
The motion was approved 5-0.
C/Nice made a motion, seconded by C/Tamaya, to recommend
the Walnut Sheriff's Department Radar Trailer be placed on
the streets referred to in the Neighborhood Traffic Study
on a regular basis. The motion was approved 5-0.
