David Bodin who lives near the intersection of Temple Avenue and Golden Springs Drive. He believes

signal on Temple Avenue.
DPW/Liu indicated that Diamond Bar staff is working with Pomona to effect a solution for this location.
A Randy Akner from La Petite Academy, 722 S. Grand Avenue, requested a barrier be installed to
protect the students from vehicles that might enter the playground area. A recent accident occurred at
this location with a truck landing in the playground area.
DSA/ Smith indicated a block wall with reinforcement could be placed on private property. The City's
Planning Division would be required to approve any construction of walls or guard rails with regard to
height and placement.

DSA/Smith presented staff's report. Staff recommends that the Traffic and Transportation
Commission receive public comments and concur with staff's recommendations to install 50 feet
of red curb markings at the northeast and southeast corners of Twin Canyon Lane/High Knob
Road, and the southeast corner of Golden Springs Drive/High Knob Road, respectively.
David Bodin, 1129D Golden Springs Drive, drives out of High Knob Road daily. He agrees with

T&T COMMISSION
Jim DeVries, 1100 Twin Canyon Lane, is concerned about the length of the red curbing and
potential lack of parking for the condominiums.
DSA/Smith explained to Mr. DeVries that staff concluded that 50 feet of red curb would ensure
minimum sight.
Jim DeVries said he would like to see a left turn lane on Golden Springs Drive at High Knob
Road prior to re -paving as well as, red striping on all four corners. He suggested consideration of
additional striping (approximately 50 feet) on the west side of Golden Springs Drive from High
Knob Road toward Temple Avenue.
Sally Wagner, 1101 Twin Canyon Lane, does not believe 50 feet is sufficient to allow for safe
entry onto Golden Springs Drive from High Knob Road. There have been too many near -miss
accidents in the past to allow this situation to continue.
Following discussion, C/Istik moved, C/Leonard-Colby seconded, to instruct staff to install 50
feet of red curb markings at the northeast and southeast corners of Twin Canyon Lane/High
Knob Road, the northwest and southeast corners of Golden Springs Drive/High Knob Road,
respectively. Furthermore, the Commission requested staff to install additional red curbs as
determined by staff at all corners of the abovementioned intersections.

Speeding concerns along Cold Spring Lane, between Barbi Lane and Diamond Bar Boulevard.
DSA/Joe presented staff's report. Staff received four e-mails from individuals expressing
concerns about speeding on Cold Spring Lane. Staff recommends that the Traffic and
Transportation Commission receive public input and discuss the speeding concerns along Cold
Spring Lane, between Barbi Lane and Diamond Bar Boulevard.
Chris Chung, 21470 Cold Spring Lane, said he became aware of vehicles speeding on Cold
Spring Lane when he was moving into his home two years ago. The pavement was torn up by
INOVEMBER 9, 2000 PAGE 4 T&T COMMISSION
the utility company and not sufficiently repaired. The pavement is deteriorating. The warning
signs do not appear to deter speeding vehicles. He believes staff needs to conduct a one week
study rather than a one day study. He believes it is an unsafe environment. He would like for
the street re -paving to take place this fiscal year rather than next fiscal year. He suggested
installation of a stop sign at Diamond Ridge Road and Cold Spring Lane and the use of stamped
concrete or Botts dots to break up the consistency of the roadway.
Chair/Morris cautioned Mr. Chung that Botts dots create a certain amount of noise in the
neighborhood.
Mr. Chung indicated to C/Kung that the peak hour for speeding vehicles is in the evening and
most especially on Friday when people are traveling home from work.
Trey Hughes, 21485 Cold Spring Lane, has witnessed about 10 vehicle accidents in the 14 years
he has lived at this location. He believes the solution is police presence. The worst time is
between 4:00 and 8:00 p.m. and throughout the night.
Xi Song, 21451 Cold Spring Lane, believes a stop sign at the intersection of Diamond Ridge
Road would help to slow down the uphill traffic. He is concerned about the school children who
walk the street to Castle Rock Elementary School.
Kenneth Suh, 21506 Barbi Lane, has a great deal of difficulty getting out of his driveway because
of the traffic. He believes a three-way stop at Cold Spring Lane and Barbi Lane would help the
situation.
In response to Chair/Morris' concern for notifying residents of traffic concerns, DPW/Liu stated
that the City's postcard Community News could be used to advise residents of traffic concerns.
VC/Virginkar believes part of the solution is increased enforcement.
Chair/Morris suggested that "Watch Downhill Speed" signs be painted on the pavement.
Following discussion, Chair/Morris moved, C/Kung seconded, to instruct staff to proceed as
follows. Send a general mailing to residents regarding residential speed limits and enforcement;
increase enforcement, and conduct a more extensive study of the situation and present potential
mitigation recommendations to the Commission. Motion carried by the following Roll Call vote:

Decorah Road Traffic Concerns
Chery Cooper, 23826 Decorah Road, and her colleague Steve Granger, Board of Directors of the
Diamond Ridge, representing over 600 homeowners living in the area bounded by Sunset
Crossing Road, Golden Springs Drive and the Pomona Freeway, are also concerned about
speeding traffic in their area. There is no stop signal along the entire length of Decorah Road and
vehicles gain a considerable amount of speed on the decline. She cited driver behavior and lack
of consideration as a factor and said she believes measures like Botts dots are needed to change
driver behavior. She invited the Commission to attend a homeowners meeting to discuss this
urgent matter.
C/Kuo asked if stop signs at N. Platina Drive and N. El Encino Drive would help the situation to
which Ms. Cooper responded that she believes it would be a tremendous help.
DPW/Liu stated that soon after staff received this request from the homeowners association, staff
requested increased enforcement. In addition, staff is recommending that this matter be
discussed at the December 14 Traffic and Transportation Commission meeting which begins at
6:00 p.m. He asked Ms. Cooper to provide staff with the homeowners association mailing list in
order to advise the 670 residents of the .meeting. Staff's report may contain recommendations for
multi -way stop signs at certain intersections and if the homeowners have any comments or
recommendations the Commission would like to hear it from both the board members and the
residents.
Ms. Cooper offered to include a statement in the November 15 newsletter from the board to the
membership that it is important that residents provide input regarding stop signs at any or all of
the intersections.

VIII ITEMS FROM COMMISSIONERS: C/Kung stated that he observed that the parking area on
Brea Canyon Road in front of the Metrolink Station is nearly fully occupied and there may again be a
parking problem in the adjacent residential areas of Diamond Bar. He suggested that the current street
parking be expanded on one or both sides of Brea Canyon Road.
DPW/Liu stated that the City of Industry intends to expand the Metrolink parking lot. In the interim, if
condition warrants, staff will contact the City of Industry for possible additional temporary mitigation
measures.
C/Istik reported on his attendance at the Traffic Commissioners Workshop. He believes that the
Commission should once again consider speed humps for residential streets. He suggested that in order
to be of more immediate assistance to the residents, some things such as red curbing could be
implemented immediately after approval by the Commission unless it is appealed or unless a Council
Member wants to have the matter agendized for the Council. He asked that this matter be agendized for
a future meeting.
DPW/Liu agreed to highlight for the Commission staff's ability to implement various mitigation
measures in accordance with the Municipal Code provisions.
