Room, 21865 East Copley Drive, Diamond Bar, California.

ROLL CALL:
Commissioners: Chairman Istik, Vice Chairman Leonard,
Gravdahl
Absent: Commissioner Ortiz
Staff: Senior Engineer, David Liu; Administrative
Assistant, Tseday Aberra; Consultant Engineer
Michael Myers; Sergeant Rawlings; and
Recording Secretary, Carol Dennis
Chair/Istik stated that Commissioner Ortiz would be absent and
excused from the meeting.
Chair/Istik requested that the Traffic and Transportation
Commission dispense with the stated meeting Agenda and begin with
the Neighborhood Traffic Management Study. The Commission
concurred.
V. OLD BUSINESS:
A. Neighborhood Traffic Management Study.
Chair/Istik declared the public comments open.
Craig Clute, 21217 Fountain Springs Road, stated that
although he had not read the report in detail, it
appears that most of the items discussed in previous
public meetings and with the steering committee have
been included. He requested that Page 4 indicate that
Castle Rock Elementary School is located on Castle Rock
Road between Bronco Lane and Cool Springs Drive. He
took exception with the statement on Page 4 of the
study which states that "the overall traffic
circulation operates with minimal constraints when
school ends in the afternoon". Regarding the Trip
Generation, Table 2-3 on Page 14, he suggested that
August 10, 1995 Page 2 T&T Commission
some of the figures might be too high. He further
stated that he would like to see "No Commercial Truck"
signs on Cold Springs Lane as well as on Fountain
Springs Road. He requested that the study indicate the
existing four-way stop at Cold Springs Lane and Brea
Canyon Road.
Chair/Istik referred the Commission to the study's
recommended actions beginning on Page 35.
Robert Close, DKS Associates, stated that the thrust of
the improvement is to put chokers on Fountain Springs
Road and Cold Springs Lane. In light of the cost of
this improvement, staff questions the effectiveness of
chokers. He cited a DKS Associates study conducted in
Atherton located in San Mateo County. Atherton
installed an active series of chokers. This
effectively reduced cut -through traffic by 75 percent.
In addition, the average speed was reduced by 10
percent. DKS Associates believes that the
implementation of chokers is an integral part of the
solution to the cut -through traffic and vehicular
speeding problems associated with the neighborhood..
DKS Associates has included the chokers as Part Two of
Plan I because the funding and plan design for this
implementation may require greater consideration on the
part of the City. However, DKS Associates considers
Part One and Two of the implementation plan to be
equally important. DKS Associates believes Part One
of Plan I can be implemented immediately. Prior to
implementing Plan II, Plan I implementations should be
analyzed for their effectiveness. The City may
determine that Plan II will be unnecessary if Plan I is
effective in eliminating most, if not all, of the
current traffic problems.
Responding to Chair/Istik, Mr. Close stated DKS
Associates recommends that Plan I be implemented in its
entirety.
Chair/Istik stated that if the City Council approved
Plan I the funding would be immediately available. He
indicated the total cost of Plan I, Part One and Two,
is approximately the cost of one traffic signal.

Mr. Close, responding to C/Gravdahl, stated that the
current trend indicates truck traffic enters Country
Hills Towne Center from Cold Springs Lane and exits the
center onto Fountain Springs Road, or enters the main
entrance from Diamond Bar Boulevard and exits onto
Fountain Springs Road. With the implementation of Plan
I, it is expected that trucks travelling through the
neighborhood and finding chokers would most likely use
another route.
In response to Chair/Istik, Mr. Close stated that he
did not believe trucks would use alternative routes to
avoid the physical restrictions on Cold Springs Lane
and Fountain Springs Road. In his opinion, the
effectiveness of Plan I should be studied in order to
avoid the implementation of Plan II which would be
overkill.
Chair/Istik suggested that the Commission consider a
motion to send a recommendation to the City Council
which would not include any financial considerations.
A motion was made by C/Gravdahl and seconded by
C/Leonard to recommend that the City Council adopt Plan
I, Part One and Two and conduct a follow up study to
determine the effectiveness of Plan I prior to
implementation of Plan II.
Chair/Istik stated that he would support the motion if
it included a recommendation for a "right turn -out
only" reconstruction of the Country Hills Towne Center
driveway at Fountain Springs Road. He recommended that
the shopping center management discuss the neighborhood
concerns for truck traffic with the tenants and seek
their cooperation.
C/Gravdahl and Vice-Chair/Leonard concurred with
Chair/Istik and the motion was revised.
The motion was approved 3-0 with the following roll
call:
AYES: COMMISSIONERS: Gravdahl, VC/Leonard,
Chair/Istik
NONE: COMMISSIONERS: None
ABSTAIN: COMMISSIONERS: None
ABSENT: COMMISSIONERS: Ortiz

VI. NEW BUSINESS
A. Request to install speed bumps on Decorah Road.
AA/Aberra stated that in February, 1992, the Traffic
and Transportation Commission discussed the issue of
speed bumps and recommended to the City Council denial
of installation.
Staff recommends that the Traffic and Transportation
Commission deny the request to install speed bumps on
Decorah Road. Staff recommends the installation of 25
MPH" signs and double -yellow centerline striping on
Decorah Road as indicated in the plan attached to the
staff report.
Responding to Chair/Istik, SE/Liu stated that the City
does not have a formal policy with respect to speed
bumps. He stated there was an opinion issued by the
previous City Attorney.
Chair/Istik declared the public comments open.
Chinh Pham, 24145 Decorah Road, related the hazards of
speeding vehicles in his neighborhood. Since a 25 MPH
would involve voluntary compliance on the part of the
driver, he indicated he feels a speed bump would
promote involuntary compliance. He stated that is very
concerned about numerous near -accidents and he fears
for the safety of children who might move into the
area. In lieu of a speed bump, he indicated he would
favor the installation of a 25 MPH speed sign and
double yellow striping.
Mercedes Hernandez, 23943 Decorah Road, stated her
residence is located two houses from Del Sol Lane. She
indicated she cannot allow her children to be outside
of the house because of the vehicles speeding down the
hill. She indicated she would like to have a stop sign
or a speed bump to slow the traffic. She further
stated that she believes law enforcement targets Del
Sol Lane for speeding.
Dennis Block, 23746 Decorah Road, stated he has lived -"
in the neighborhood for 23 years and his street has
been a drag strip since he moved there. He further
stated he would hope that stop signs and speed bumps

T&T Commission
would deter the speeding traffic. He indicated that
during a week the law enforcement officers patrolled
the street there was no speeding. He stated he is not
aware of any accidents in the area during the time he
has lived there.
Chair/Istik stated he concurs with staff's
recommendation. City's such as Pasadena have adopted
speed hump policies. In these instances, speed humps
are not permitted when the street grade exceeds five
percent because of the safety concerns. Sixty-five
percent of residents who would be effected by the
installation of speed humps must concur by signing an
agreement. In addition, the City's Engineer and the
City Council must agree that such an installation is
safe. If there is a request to remove the speed hump,
sixty-five percent of the residents must agree to the
removal.
C/Gravdahl stated he drove the area and concurs with
the residents that there is a need for mitigation of
the speeding problems. He further stated he is
concerned that the installation of speed bumps in the
tract would increase the noise level. Regarding the
hairpin turn at Navajo Springs and Decorah Road,
striping is needed. He recommended the City install
downhill speed and curve signs to alert motorists. He
stated with the addition of the signs he would concur
with staff's recommendation.
SE/Liu, in response to C/Gravdahl, stated "Watch
Downhill Speed" and "Curve" signs can be supplemented
with the 25 MPH signs.
C/Gravdahl stated there are hills all through the 30
year old tract and that there are no center lines and
no speed control signs. He recommended that staff
review the entire tract for striping at the curves.
A motion was made by C/Gravdahl and seconded by
C/Leonard to approve staff's recommendation and
supplement "Watch Downhill Speed" and "Curve" signs.
The motion was approved 3-0 with the following roll
call:
AYES: COMMISSIONERS: Gravdahl, VC/Leonard,

Chair/Istik requested concurrence from the Commission to have a
discussion regarding a speed bump policy for the City of Diamond
Bar.
C/Gravdahl requested an opinion on speed bump policy from the
City Attorney.
Responding to Chair/Istik's request, SE/Liu stated staff will
work with the City Manager to obtain an opinion from the City
Attorneyfs office. In addition, staff will provide copies of the
three year old Speed Bump Study as an informational item for the
September 14 Traffic and Transportation Commission meeting.
A motion was made by VC/Leonard and seconded by C/Gravdahl to
carry over the balance of the agenda items to the September 14,
1995 Traffic and Transportation meeting. The motion was approved
3-0 with the following roll call:
AYES: COMMISSIONERS: VC/Leonard, Gravdahl,
