July 25, 1996 Page 2 T&T Commission
Craig Clute, Fountain Springs, asked for smaller
warning signs on Fountain Springs Road. He requested
the City research the Diamond Bar High School parking
restrictions and signs. He suggested the City consider
diagonal parking in the redesign phase of Brea Canyon
Road.
DDPW/Liu responded to Chair/Istik that the conceptual
Brea Canyon Road improvement plan is complete.
Discussion for this item is slated for the October
Traffic and Transportation Commission meeting.
Chair/Istik asked DDPW/Liu to make the plans available
to Mr. Clute.
V. OLD BUSINESS
A. Cul-de-sacing Sunset Crossing Road from SR 57 off -
ramp to the westerly City limit. 1_7
Chair/Istik asked staff to revise the report to
include discussion of narrowing Sunset Crossing
Road from the SR 57 off -ramp to the cul-de-sac.
DPW/Wentz stated the City Council directed staff
to determine the feasibility of cul-de-sacing the
end of Sunset Crossing Road and installing a
pocket park. He indicated staff is aware of the
Commission's concerns regarding the width of
Sunset Crossing Road with respect to current and
future street use. With the Traffic and
Tranpsortation's request, staff will research
additional alternatives and pursue further City
Council consideration.
Chair/Istik stated the narrowing of Sunset
Crossing Road would be consistent with the
approved cul-de-sacing.
DPW/Wentz responded to Chair/Istik that raised
barriers are proposed for the end of the cul-de-
sac which causes the traffic to enter the parking
area. The parking will extend to the existing
curb and gutter on both sides and will be striped 7-7
on the existing pavement. The pocket park will be
the full width of the westerly street extending -
about 70 feet easterly from the City limit. City
July 25, 1996 Page 3 T&T Commission
Council has approved the design process of Phase
II.
C/Tamaya stated Mayor Pro Tem Huff is concerned
about the potential cost to narrow the street.
DPW/Wentz responded that staff will consider each
alternative offered by the Commission and estimate
the costs involved.
C/Tamaya indicated that although the MRF is being
relocated, it is feasible to believe that the City
of Industry intends to develop the area at some
future date.
C/Nice suggested the Sunset Crossing Road
residents be surveyed. DPW/Wentz concurred.
Responding to Chair/Istik, DPW/Wentz stated the
intent of Phase II is to remove a portion of
asphalt and create a lack of continuity between
the City's limits. Chair/Istik stated that some
of the right-of-way could be vacated to make it
unavailable for connecting the two cities.
VC/Leonard stated her approval of a street median
alternative.
VC/Leonard made a motion, seconded by C/Tamaya to
request DPW/Wentz to confer with the City Manager
regarding the Commission's direction and direct
staff to present recommendations and related costs
at the Traffic and Transportation Commission's
September meeting. Without objections, the motion
was so ordered.
VI. NEW BUSINESS
A. Draft Speed Hump Policy for the City of Diamond
Bar.
DDPW/Liu read the staff report into the record.
Staff recommends the Traffic and Transportation
Commission discuss and address the issues raised
in the report.
Chair/Istik conducted a straw poll of the
July 25, 1996 Page 4 T&T commission
Commission which resulted in VC/Leonard, C/Nice
and C/Virginkar (by proxy) being opposed to speed
humps and C/Tamaya and Chair/Istik in favor of
speed humps with restrictions.
DDPW/Liu responded to C/Tamaya that he believes
the City of Chino Hills' speed bumps were
installed by San Bernardino County.
Chair/Istik asked for public comments.
Craig Clute stated he is in favor of speed humps
with restrictions to slow the residential traffic.
He asked for the opportunity to review the City's
proposed speed hump policy.
Don Gravdahl stated that in his opinion, speed
humps are a liability and believes the City
Attorney would recommend no speed humps in Diamond
Bar.
DDPW/Liu stated the City Attorney's opinion is
that speed humps are a roadway design feature and
not a traffic control device. He advises that a
speed hump policy is dependent upon a risk
benefits analysis. Consideration would be limited
to speed humps on streets with a grade of 5
percent or less.
DPW/Wentz stated staff's policy is no speed humps.
The discussion concerns whether the Commission
wishes to recommend that the City Council adopt a
different policy.
C/Tamaya reiterated he favors a restricted speed
hump policy for streets of less than 5 percent
grade and with 75 percent of the community
favoring a policy with speed humps placed in
residential areas where small children are
present. He indicated his concern that residents
should be notified prior to any installation
taking place.
C/Nice respectfully disagreed with C/Tamaya. He
suggested that any resident who may wish to
consider a speed hump in their neighborhood be
July 25, 1996 Page 5 T&T Commission
provided City literature explaining the reason for
the City's "No Speed Hump" policy.
Chair/Istik stated he believes speed humps may be
beneficial in some instances. He further stated
that the City of Pasadena has indicated the
vehicle speed has decreased by three to five miles
per hour as a result of speed hump installations.
VC/Leonard recommended "No Speed Hump" policy and
cited the potential liability and the
implementation costs. She reminded the Commission
that C/Virginkar has expressed his opposition to
the speed hump policy.
B. Request to install a stop sign and centerline
striping at the intersection of Morning Canyon
Road and Presado Drive; and,
C. Request to install a stop sign on Minnequa Drive
at Bower Cascade Place.
AA/Aberra stated staff has investigated both
intersections in question and is presenting these
items to the Commission for consideration under
its previously established policy.
Chair/Istik asked for public testimony.
Mr. Gravdahl reiterated his request for a stop
sign on Minnequa Drive at Bower Cascade Place. He
indicated that in his opinion, potential exists
for a fatal accident at the intersection.
DPW/Wentz
stated that the
potential liability
involving
speed humps rests
with the City.
C/Tamaya made a motion, seconded
by Chair/Istik to
continue with the City's
current policy of "No
Speed Humps".
The motion
passed with the
following

Chair/Istik asked for public testimony.
Mr. Gravdahl reiterated his request for a stop
sign on Minnequa Drive at Bower Cascade Place. He
indicated that in his opinion, potential exists
for a fatal accident at the intersection.
July 25, 1996 Page 6 T&T Commission
Mr. Clute stated that in general, stop signs are
permanent and require warrant justification and
enforcement.
DPW/Wentz stated that if the Commission finds
merit for installation of a stop sign at one leg
of an intersection, the Commission must state the
reasons for justification. If the Commission
recommends stop signs at all three legs of an
intersection, staff recommends a warrant study.
With respect to Item C., C/Tamaya made a motion,
seconded by VC/Leonard, to install a stop sign on
Minnequa Drive at Bower Cascade Place. Without
objections, the motion was so ordered.
With respect to Item B., VC/Leonard made a motion,
seconded by C/Tamaya, to install a stop sign on
Presado Drive at Morning Canyon Road. The motion
failed with the following Roll Call vote:
AYES: COMMISSIONERS: VC/Leonard, Tamaya
NOES: COMMISSIONERS: Nice, Chair/Intik
ABSTAIN: COMMISSIONERS: None
ABSENT: COMMISSIONERS: None
The Commission concurred to accept staff's
recommendation for no centerline striping at the
intersection of Morning Canyon Road and Presado
Drive.
DPW/Wentz indicated that it is staff's intention
not to put stop signs at T -Intersections unless
there is potential need based upon sight distance,
grade and/or other vision related problems. In
the future, staff reports will detail, in an
adopted standardized format, the basis upon which
a conclusion has been reached as a foundation for
staff's recommendation. In addition, as policies
are adopted, they will be included in a Policies
Handbook.
D. Standard of practice for installation of
centerline striping for residential streets in the
City of Diamond Bar.
July 25, 1996 Page 7 T&T Commission
DDPW/Liu read the staff report into the record.
Staff recommends that the Traffic and
Transportation Commission concur with staff's
recommended standard of practice for installation
of centerline striping for residential streets in
the City of Diamond Bar.
Chair/Istik asked for public testimony.
Debbie O'Connor, Bower Cascade Place, referred to
Commission at her letter of July 25. She
indicated that if it is the City's practice to
visit the residential street, complete an analysis
of the number of reported accidents, and the
width, length and grade of the street, visibility,
sight distance and other potential concerns, she
would like to see the results of the study for her
neighborhood prior to installation of the of the
double yellow centerline striping. She stated
that since her March inquiry to the Department of
Public Works, she has not had a response.
Mr. Gravdahl asked when the City plans to finish
the centerline striping on Minnequa Drive. He
suggested the centerline striping consideration
include street width.
C/Tamaya asked if Mr. Gravdahl believes the
Minnequa Drive striping should be a double yellow
centerline striping. Mr. Gravdahl responded that
either a single or double yellow centerline stripe
may be acceptable.
Mr. Clute stated in his opinion, centerline
striping is not effective. Stop signs appear to
be more effective in causing motorists to stay on
the proper side of the street.
DDPW/Liu responded to C/Tamaya that in accordance
with the Commission's request, the question of
centerline striping on Minnequa Drive will be
readdressed by the Commission after the Commission
has established a centerline striping policy. In
response to Mrs. O'Connor, the City did not, at
the time of centerline striping the residential
streets, notify the residents. Staff agrees that
July 25, 1996
Page 8 T&T commission
notification should be considered with respect to
future requests. He indicated the residents views
are mixed with respect to vehicles passing on the
wrong side of Minnequa Drive.
VC/Leonard stated that she believes a single
yellow centerline stripe on Minnequa Drive would
suffice. Double yellow centerline striping is
overkill. She indicated she was able to drive on
the proper side of the street except in the curved
area where the motorhome is parked. In general,
sight visibility is good and she observed
motorists driving safely.
Chair/Istik voiced his concerns that too many stop
signs and too much striping is being installed
within the City. He stated he would prefer to
have certain criteria such as sight distance and
accident history trigger a yellow center line
installation.
DDPW/Liu responded to C/Nice that staff's
observations are reflected in the staff report
presented to the Commission.
Responding to Mrs. O'Connor and VC/Leonard,
DDPW/Liu indicated that the Commission could
request staff to re-evaluate and/or sandblast
certain portions of a street in order to remove a
double yellow centerline stripe. Staff's
recommendation is to keep the Minnequa Drive
double yellow centerline striping in place.
DPW/Wentz stated staff will reconsider the double
yellow centerline striping on Minnequa Drive and
bring a recommendation back to the Traffic and
Transportation Commission on September 12, 1996.
C/Tamaya made a motion, seconded by C/Nice, if
staff's recommendation is to stripe the unstriped
areas of Minnequa Drive, that it be striped with
dashed yellow centerline striping. The existing
double yellow centerline striping will be
reconsidered for dashed yellow centerline. i
DPW/Wentz responded to Chair/Istik that staff will
