July 18, 1994 as discussed.
II. COMMISSION COMMENTS
C/Gravdahl inquired about the accident rate at the intersection of
Pathfinder Road and Diamond Bar Boulevard with relation to the
northbound Diamond Bar Boulevard traffic turning west onto
Pathfinder Road.
SE/Liu responded that a left -turn signal warrant study was
conducted at the intersection of Pathfinder Road and Diamond Bar
Boulevard last year and at the July 19, 1994, City Council meeting
a budget of $30,000 for left -turn phasing was approved.
August 11, 1994 Page 2 T&T Commission
Sgt. Rawlings asked for clarification regarding the time frame for
the accident count needed. It was decided a one-year report would
be given to staff to forward to Commissioner Gravdahl.
C/Gravdahl commented that the northbound traffic on Diamond Bar
Boulevard, at the left -turn arrows onto SR -60 eastbound near
Palomino Drive, backs up with cars and blocks Palomino Drive.
C/Gravdahl stated that he had been contacted by a resident of
Palomino Drive asking for "DO NOT BLOCK INTERSECTION" pavement
marking on Diamond Bar Boulevard. He further commented that at
3:30 p.m. the right -turn pocket between Diamond Bar Boulevard and
Palomino Drive and the eastbound SR -60 allows for six cars. He
asked about the adequacy of length between the intersection of
Palomino/ Diamond Bar Boulevard and the SR -60 on-ramp and if the
spacing for another signal would be a problem.
Consultant Siecke, responded that these items are taken into
consideration during a traffic signal warrant study.
SE/Liu responded that the intersection of Diamond Bar Boulevard and
Palomino Drive is scheduled for a traffic signal warrant study in
this Fiscal Year along with eight other areas. The findings of
these studies will be brought to the Commission for review.
C/Chavers requested that the geometric options of the intersection
be considered at the time of the traffic signal warrant ctud.1
because of the tight spacing and co-ordination with CalTrans.
III. PUBLIC COMMENTS
Dr. Lawrence Rhodes, 594-8178, requested the Commission to look
into the following items: 1. Parking on the west side of Brea
Canyon Road north of SR -60: 30 -minute parking for commercial
vehicles is constantly violated. He recommends that the area be
posted "No Parking". 2. Brea Canyon Road south of Lycoming Street
and south of the Preschool, he requested a right -turn only lane for
the southbound Brea Canyon Road traffic onto the westbound SR -60.
3. On Lycoming Street east of Brea Canyon Road, he requested "No
Commercial Parking." 4. On Washington Street between Brea Canyon
Road and Lincoln Avenue, he requested "No Overnight Parking".
There is no need for the residents' parking since there is no
access to the homes in the area and because of the number of
abandoned vehicles he has called into the Sheriff's Department. 5.
The green -time for the eastbound SR -60 Off -ramp at Golden Springs
Drive (Brea Canyon Road off -ramp) is 15 seconds too long than it
needs to be for the Golden Springs Drive traffic. He requested a
time study to increase the green- time for the freeway traffic. 6.
The same off -ramp has numerous pot -holes and is need of repair. He
requested the City notify CalTrans to see if they would fix it.
SE/Liu responded that regarding the violation of 30 -minute parking
on the westerly side of Brea Canyon Road north of the SR -60 as well
as the right -turn only lane on Brea Canyon Road onto SR -60
westbound, staff will conduct investigative study and bring back to
August 11, 1994 Page 3 T&T Commission
the Commission for review.Regarding the parking on Lycoming
Street east of Brea Canyon Road, the request for "No Commercial
Parking" has been included in .the item forwarded to the City
Council. However, the addition of Lycoming Street east of Brea
Canyon Road is to have "No Stopping" between Brea Canyon Road and
Silver Fir Road during the hours of 10:00 p.m. and 6:00 a.m. The
Public Works Department will convey Dr. Rhodes' concerns regarding
the Brea Canyon Road off -ramp at eastbound SR -60 to CalTrans.
Dr. Rhodes commented that these restrictions force the residents to
move their cars, but "No Commercial Vehicles" would not.
SE/Liu responded that the State Attorney General's Office issued an
opinion stating that a City has no authority to prohibit the
parking of particular categories of vehicles on its residential
streets.
Sgt. Rawlings commented that the enforcement of time limits is
difficult.
C/Chaver asked for clarification regarding the State law on parking
enforcement and private vendors.
Sgt. Rawlings responded that the passing of AB 408 a year ago makes
parking citations a civil, not a criminal matter. The City of
Diamond Bar is currently using the Sheriff's Department as the
enforcement agency for parking citations, but handles its own
processing of these citations via City Hall. Some cities in the
Los Angeles area have private vendors who process both the citing
and the collecting.
IV. CONSENT CALENDAR - None
V. OLD BUSINESS - None
VI. NEW BUSINESS - None
A. City Wide speed Zone survey
SE/Liu reported that the City of Diamond Bar conducted a City
Wide Speed Zone Survey in June of 1989 and the City Council,
on September 19, 1989, adopted Ordinance No. 22(1989) to
approve said survey.
In order to enforce speed limits
by radar or other electronic
devices, a speed study must be
conducted
every five years.
Section 40802 of the California
limit enforced by radar and "...which
Vehicle Code defines a speed
speed limit is not
justified by
an engineering and traffic
survey conducted
within five
years prior to
the date
of the alleged
violation..."
constitutes a speed
trap.
Since speed traps
are illegal,
the lack of an
adequate
study effectively
precludes the
Sheriff Department
from using
radar enforcement.
August 11, 1994 Page.4 T&T commission
Through adoption of this study, the Sheriff Department will be
able to enforce posted speed limit with radar equipment.
The report being presented reflects the result of an
engineering and traffic survey for the establishment of speed
limits on City streets as required by Sections 22357 and 22358
of the California Vehicle Code.
In this update five streets have been added: Chino Avenue,
Kiowa Crest Drive, Palomino Drive, Walnut Drive and Washington
Street. This report is given to the Commissions for review
and comments. The same report will be presented to the City
Council on August 16, 1994, and staff is recommending the
adoption of a resolution to continue radar enforcement on
these City streets.
Chair/Ortiz asked for clarification on Chino Hills Parkway as
presented in the study.
Consultant Siecke responded that the recommendation is to
maintain the existing speed limit of 45 mph based upon
critical speeds, condition of the roadway, consistency with
the connecting speed limits in neighboring cities of Pomona
and Chino Hills, and the accident rate comparison of actual to
expected.
Chair/Ortiz asked if 55 mph or 50 mph were considered since
the limit had once been 55 mph on Chino Hills Parkway, and the
day, and time the speed Zone Survey was conducted. He asked
if there would be a safety issue involved if the speed limit
was raised to 50 mph or 55 mph from 45 mph.
SE/Liu responded that the speed zone study for Chino Hills
Parkway was conducted in 1991 after the completion of the
road, and that the study also recommended 45 mph and was
posted as such.
Consultant Siecke responded that maintaining the 45 mph
existing speed is appropriate for the roadway, re -iterating
continuity as a major factor. He further stated that the
length of the segment is slightly over one-half mile, and
planners try to avoid fluctuation of speed limits over a
roadway that is consistent in character. Regarding the day of
the week, Consultant Siecke, responded the study was done on
Friday, April 29, 1994, from 13:15 to 13:45, one -hundred
samples. He commented that speed zone studies are typically
done in off-peak hours when traffic flows freely and speeds do
not tend to vary day to day. Regarding 50 mph and 55 mph, he
said that enforcement might be difficult for the other cities,
but that he did not think a safety issue would be involved.
Chair/Ortiz asked about the speeds on Kiowa Crest Drive.
August 11, 1994 Page 5 T&T Commission
Consultant Siecke responded that Kiowa Crest Drive is a
residential street, but due to its uninterrupted length over
a mile, it requires a traffic and engineering survey to
establish the speed limit. In accordance with the CalTrans
Traffic Manual, the recommendation justifies a greater than 25
mph speed limit for this residential street. The study
concluded the traffic at the 85 percentile was traveling at 39
mph, so the recommendation is for 30 mph. This is an increase
of 5 mph, but is enforceable by radar. Radar cannot be used
for enforcement if the street is posted 25 mph. He commented
that the research data indicates that the speed of a driver is
typical with the driver,'s comfort level regardless of the
posting. Therefore, with a 30 mph posting and radar
enforcement there is a potential to lower the speed from the
85 percentile traveling at 39 mph.
Sgt. Rawlings commented that with enforcement the average
speed could possibly be reduced rather than increased.
Chair/Ortiz asked staff about the concerns of Craig Clute,
21217 Fountain Springs Road, brought to the Traffic and
Transportation Commission on July 14, 1994. AA/Aberra
responded that she had made contact with Mr. Clute and staff
was handling the matters administratively while maintaining
contact with him.
Chair/Ortiz asked staff to comment on the recommendation for
30 -mph, including comments regarding the accidents, citizen
concerns and letters to City Hall.
Consultant Siecke, responded that the recommendation for
Prospectors Road is 30 mph. He further indicated that the 85
percentile is at 38 mph and is therefore similar to the Kiowa
Crest situation. In order to enforce the speed limit with
radar, not constituting a speed trap, the posting cannot be"25
mph. Within the school .zone, 25 mph would still be
applicable. The traffic accident count is very low and is not
considered a safety hazard.
SE/Liu responded that he was unaware of any citizen concerns.
C/Chavers commented that prima-facie speed limit is 25 mph in
residential areas. By raising the speed limit on Kiowa Crest
Drive, Palomino Drive, and Prospectors Road, it - would be
setting a precedent. Since the City of Diamond Bar has no
adopted General Plan, including a Circulation Element with
certain street classifications, a policy has not been
established. Such a policy may yet be established.
Therefore, the Commission should recommend to the City Council
that a closer look be taken with regard to these residential
streets.
SE/Liu commented that Ordinance 22 will need to be amended and
that the additional streets would be discussed at that time.

T&T Commission
The Resolution which will be brought before the City Council
on August 16, 1994, if adopted, will approve the study and
allow the Sheriff's Department to continue radar enforcement
on City streets based on the current Speed Zone Study only.
C/Gravdahl asked about the Palomino Drive enforcement.
Sgt. Rawlings responded that radar enforcement is easier and
that pacing a vehicle on a residential street is very
difficult. -
C/Chavers moved, seconded C/ Gravdahl, to recommend to City
Council the adoption of Speed Zone Survey as presented with
exception of Kiowa Crest Drive and Palomino Drive, and
recommend that a policy discussion be considered with regard
to the raising of speed limits in residential streets from the
prima-facie speed limit of 25 mph.
The Motion was passed unanimously with the following ROLL CALL
vote:
AYES: Chavers, Gravdahl, Esposito, Chair/Ortiz
NOES: None
ABSTAIN: None
ABSENT: None
Chair/Ortiz turned the meeting over to C/Ghavers and was excused at
8:00 P.M.
VII. STATUS OF PREVIOUS ACTION ITEMS
SE/Liu commented that the recommendation for parking restrictions
on Brea Canyon Road is being forwarded to the August 16, 1994 City
Council meeting.
VIII. ITEMS FROM COMMISSIONERS
C/Chavers requested information or an overview on the Regional
Studies of the Four Corners Study lead by SLAG, the San Gabriel
Valley Bikeway Master Plan conducted by LACMTA which is in
progress, and the Pomona Valley's Traffic Signal Synchronization
Program for inter -jurisdictional arterial co-ordination.
Consultant Siecke responded that he had attended a meeting this
afternoon of the Four Corners Group. The issues of Soquel Canyon
and Tonner Canyon are being discussed and there is a difference of
opinion. The north Orange County cities are opposed to a road
coming through Tonner Canyon, and the cities of Chino Hills and
Diamond Bar have the position that the road is necessary. The
Counties involved are Orange, San Bernardino, and Los Angeles. The
road is on the San Bernardino Master Plan, but not on the Orange
County or Los Angeles County Master Plans. A sub -committee will be

T&T Commission
formed to look into ways of solving the disagreement and a
September meeting is scheduled.
SE/Liu commented that he will keep the Commission abreast of the
updates/ developments of these subject matters and would convey the
request for information to the City Manager who is a member of the
Four Corners Committee. Regarding the San Gabriel Valley Bikeway
Master Plan, he has been in touch with the MTA and they are still
gathering data.
AA/Aberra commented that the draft San Gabriel Valley Bikeway
Master Plan Study is scheduled for discussion by LACMTA on
September 13, 1994.
IX. ITEMS FROM STAFF
CalTrans' standards of Bike Lanes and sound walls were forwarded to
the Commissioners for their information. With regard to the bike
lanes, staff is reviewing Diamond Bar's bicycle lane system, as
well as, working with the San Gabriel Valley Bikeway Mater Plan for
compliance with state requirements. This will be brought back to
the Commission at a later date.
C/Chavers asked Sgt. Rawlings to comment on the vehicle code with
respect to a motorist and adjacent bike lane at the intersection or
e7 solid white line. In his readings he has read,."when making a
right turn, pull as far right as possible." Does this mean to the
curb or the solid white line?
Sgt. Rawlings commented that this section of the California Vehicle
Code is used most often when evaluating accidents to determine
causes more than for enforcement.
Consultant Siecke commented by saying that he thought there was a
section of the Code that states no motorized vehicle will drive in
a bicycle lane except within 200' of the intersection.
C/Chavers commented 200' is the distance between Palomino Drive and
the freeway ramps and asked staff to provide a copy of the state
standards to Mr. Van Winkle who has expressed concerns on this
matter.
X. INFORMATIONAL ITEMS - None
