FEBRUARY 27, 1992
CALL TO ORDER: Chairman Chavers called the meeting to order at
6:36 p.m. at the South Coast Air Quality Management
District Hearing Room, 21865 East Copley Drive,
Diamond Bar, California.
ROLL CALL: Commissioners Ortiz, Beke, Vice Chairman Gravdahl,
and Chairman Chavers. Commissioner Fritz arrived
at 7:24 p.m.
Also present were City Engineer Sid Mousavi,
Administrative Analyst Tseday Aberra, Associate
Engineer David Liu, Deputy Clark, and Contract
Secretary Liz Myers.
MINUTES:
Feb. 13, 1992 Motion was made by C/Beke, seconded by C/Ortiz and
CARRIED UNANIMOUSLY to approve the Minutes of
February 13, 1992.
COMMISSION C/Ortiz and Chair/Chavers thanked staff and the
COMMENTS: Sheriff Department for all the work they've done
for the Commission in the last couple of years.
PUBLIC COMMENTS: Leslie Stoltz, residing at 1755 Ano Nuevo, and Judy
MacFadden, residing at 1344 Spruce Tree expressed
their concern that the traffic pattern at the Maple
Hill Elementary School is hazardous to the school
children. They inquired if the Commission could
advise them how to mitigate the situation.
Chair/Chavers stated that the traffic situation at
the Maple Hill Elementary School was reviewed about
two years ago, and some changes were made at that
time. He requested staff to determine what changes
had been made, and to revisit the site to determine
the changes in the traffic patterns. The matter is
to be placed as an agenda item for the next
meeting. It is suggested that the parents and the
school officials attend the meeting for discussion.
Leslie Stoltz informed the Commission that the "No
Parking" signs posted are not being observed. Two
years ago, the school had a staggered start time,
however, presently, all children arrive and leave
school at the same time.
OLD BUSINESS:

C/Beke informed
the Commission that
the sub -
Median island
committee met to
review the traffic situation at
Modification
the Century 21/Medical Plaza to determine
possible
Grand, between
solutions for a
safe ingress and egress
from the
Montefino and
driveway. One of
the problems is turning
right out
Diamond Bar Blvd.
of the driveway.
The other problem is
the left
February 27, 1992 Page 2
turn moves out of the driveway, and the right exit,
plus weave to make left turns at the corner.
AE/Liu reviewed the possible solutions considered
for the right turn movements: modify or widen the
drive approach, between Century 21 and the Medical
Plaza, to an alley type drive approach; and make a
10 foot stripe area, basically from Montefino Ave.
to the Fire Station, creating a channelization area
for an easier turning movement. There are two
existing vents, belonging to Southern California
Edison, at the drive approach for the Medical Plaza
and Century 21. The cost to relocate the two vents
and modify the drive approach is about $3,000
dollars. The cost for the other drive approach,
between the Lucky Center and the Medical Plaza, is
included in the Grand Ave. modification project
that will probably commence next week. As a
possible solution for the left turn movements,
ingressing and egressing out of the site, the
timing plans should be studied at the
Montefino/Grand signal and the Diamond Bar
Blvd./Grand signal, to possibly create a lag to
hold part of the queue moving down to Diamond Bar
Blvd.
C/Beke stated that it was also considered creating
an alley type return, and putting a center line
stripe on the driveways. He suggested that the
timing plans be looked at by DKS as a project.
Chair/Chavers suggested that prohibiting the left
turn movements on Grand, during peak hours, be
considered, particularly from Grand into the
driveways.
AE/Liu stated that the owners of the driveways have
not yet been approached regarding funding for the
driveway modification.
Motion was made by C/Beke, seconded by VC/Gravdahl
and CARRIED UNANIMOUSLY to recommend to the City
Council to proceed with the modifications of the
three driveways, and the two utility vents on Grand
Ave., to facilitate right turns out of the Century
21/Medical Plaza and to create a 10 foot
channelized island along the curb from Montefino to
past the Fire Station/Library.
AYES: COMMISSIONERS: Beke, Ortiz, VC/Gravdahl
and Chair/Chavers.
NOES: COMMISSIONERS: None.
ABSENT: COMMISSIONERS: Fritz.
February 27, 1992 Page 3
Motion was made by C/Beke to explore the timing
sequence between the Montefino Ave./Grand Ave. and
the Diamond Bar Blvd./Grand Ave. intersection to
see if we could do something to create a break in
the queue between Montefino Ave. and Diamond Bar
Blvd. by adjusting the timing.
Summitridge/ CE/Mousavi reported that the sub -committee met to
Brookwood evaluate the circulation problems in the
Summitridge/Brookwood community. He reviewed the
recommendations made: restripe the old, faded
striping; installing bop dots (white markers);
installing 25 mph speed limit signs in certain
areas; red curbing; centerline yellow striping; and
studying the intersections of Thunder
Trail/Summitridge, Brookwood/Long View, and
Brookwood/Summitridge for stop signs. Currently,
there are funds available in the budget to do the
suggested projects.
VC/Gravdahl informed staff that the stop sign at
Carpio is set back too far, there's no stop bar,
and it's visibility is hindered by a tree. Also,
there is no sign posted for the Fire Station in the
area.
Motion was made by Chair/Chavers, seconded by
' C/Ortiz and CARRIED to direct staff to proceed with
the striping, the guide signs, the bop dots, design
effort notification, and to initiate the count
program for the stop signs previously indicated.
Chair/Chavers suggested that C/Beke's motion be
tabled until the other recommendations have been
completed, and observed.
C/Beke suggested that DKS study the project, if
funding is available.
CE/Mousavi stated that there has been discussion
regarding the possibility of the synchronization of
the signals on Grand Ave. There's money available
as part of that pilot program.
Chair/Chavers, in response to VC/Gravdahl inquiry
regarding prohibiting left hand turns exiting the
Century 21/Medical Plaza, suggested that it be
considered when no other alternative exists.
Motion was made by C/Ortiz, seconded by VC/Gravdahl
and CARRIED UNANIMOUSLY to table C/Beke's first
motion.
Summitridge/ CE/Mousavi reported that the sub -committee met to
Brookwood evaluate the circulation problems in the
Summitridge/Brookwood community. He reviewed the
recommendations made: restripe the old, faded
striping; installing bop dots (white markers);
installing 25 mph speed limit signs in certain
areas; red curbing; centerline yellow striping; and
studying the intersections of Thunder
Trail/Summitridge, Brookwood/Long View, and
Brookwood/Summitridge for stop signs. Currently,

White Paper AA/Aberra reported that, at the last meeting, the
Chairman requested that the Commission members
provide additional input to the items in the draft
"White Paper".
Chair/Chavers distributed copies of the draft
"White Paper", and indicated that it is a
consolidation of the input received from the
Commission.
Chair/Chavers called a recess at 7:30 p.m. to
review the item. The meeting was called back to
order at 7:35 p.m.
VC/Gravdahl suggested that item #16, referring to
speed humps/bumps, have an attachment.
Chair/Chavers maintained that the issue of speed
humps/bumps should not be decided at the Commission
level, but be discussed at a higher and broader
level.
The Commission briefly discussed the issue of speed
humps/bumps. They concurred that any further
discussion should be separate from this item.
Motion was made by C/Fritz, seconded by C/Ortiz and
CARRIED UNANIMOUSLY to present to the City Council
this finalized "White Paper".
AYES: COMMISSIONERS: Ortiz, Beke, Fritz,
VC/Gravdahl, and
Chair/Chavers.
NOES: COMMISSIONERS: None.
ABSENT: COMMISSIONERS: None.
Speed Humps/BumpsAA/Aberra reported that the comments made by the
City Attorney, regarding the issue of speed
humps/bumps, has been forwarded to the Commission,
as requested.
Deputy Clark stated that the two different cities'
traffic committee meetings he has attended, nobody
has been in favor of speed humps/bumps.
C/Beke and C/Fritz stated that the City Attorney
has already stated his view, opposing the use of
February 27, 1992 Page 5
speed humps/bumps, to the Council. There is no
reason for the Commission to dispute this.
Chair/Chavers pointed out that it is up to the
Council to create a policy one way or the other.
The burden should not be upon this Commission.
Motion was made by C/Fritz, seconded by C/Beke and
FAILED to recommend to the Council that they adopt
a policy which is against the installation of speed
humps based on the advise from Council that it
would enhance the liability of the City. It is
recommended that the decision be made in a public
hearing fashion.
AYES: COMMISSIONERS: Beke and Fritz.
NOES: COMMISSIONERS: Ortiz, VC/Gravdahl, and
Chair/Chavers.
ABSTAIN: COMMISSIONERS: None.
VC/Gravdahl indicated that it was suggested by two
Councilmembers that all documentation, pro and con,
be attached to item #16 of the "White Paper" for
Motion was made by C/Fritz, seconded by VC/Gravdahl
and CARRIED UNANIMOUSLY to add item #17 to the
"White Paper" relating to speed humps, which in
effect states that speed humps have come up
frequently as a request, and opinions are divided
both on the Commission, and in the literature, and
we think that given the frequency with which the
issue comes up, the City should have formally a
policy position on whether or not speed humps are
an appropriate traffic control measure. The matter
is to be tabled until after discussion with the
Council with the "White Paper".

discussion at the study session.
CE/Mousavi, in response to C/Beke, stated that
staff has received various requests for speed
humps. One request was denied by the Commission.
The other requests are pending discussion by the
Commission regarding this issues.
C/Fritz stated that, to conserve the Commission's
time, a policy should be established one way or the
other. He suggested that item #17 be added to the
"White Paper", as a speed hump item, explaining
that opinion is divided.

CE/Mousavi stated that staff will inform those
requesting speed humps that the issue is being
considered.
TTC CE/Mousavi reported that, as per Commission's
Sub -committee request, this item was placed on the agenda for a
five minute discussion on determining if it is
desired to have a sub -committee handle some
transportation issues, or if it should remain
handled by the Commission as a whole.
Motion was made by Chair/Chavers, seconded by
C/Ortiz and CARRIED UNANIMOUSLY to indefinitely
table the matter, until after the formation of the
new Commission, and until such time that it is
appropriate to discuss it again.
The Commission noted that items #1,12 and #10, of
the attached miscellaneous items included in the
staff report, can be handled administratively.
CE/Mousavi stated that staff will handle the items
and place them on the Consent Calendar.
I
Queuing Analysis CE/Mousavi reported that the queuing analysis shows
Intersection that it is possible to create two lanes, each
Pathfinder/ direction, with the right lane westbound, from
Brea Cnyn. Rd. Pathfinder to Brea Canyon Rd. northbound; and the
left turn from eastbound Pathfinder to northbound
Brea Canyon Rd.; as well as the exclusive right
turn to the freeway southbound 57. It is
recommended that the Commission review the attached
conceptual design and recommend the installation of
the 3 -way stop signs and striping modification to
the City Council.

NEW BUSINESS:
Install a Deer AA/Aberra addressed the Commission regarding the
Crossing Sign request for "Deer Crossing" signs on Grand Ave.,
near Golden Springs Drive. The Public Works
Department has researched the issue. According to
Ontario's Station's records, accidents which
involved deer have not been reported. The
southeast quadrant of the Grand Ave./Golden Springs
Drive intersection has not been identified as deer
passage by the Department of Fish and Game.
Furthermore, the Pomona Humane Society report that
no deceased deer were picked up within the City of
Diamond Bar, in the month of January 1992. It is
recommended that the Commission deny the request.
Motion was made by VC/Gravdahl, seconded by C/Beke
and CARRIED UNANIMOUSLY to accept staff's
recommendation.
AYES: COMMISSIONERS: Beke, Fritz, VC/Gravdahl,
and Chair/Chavers.
NOES: COMMISSIONERS: Ortiz.
ITEMS FROM
ABSTAIN: COMMISSIONERS: None.
C/Ortiz informed staff that there is still not a
COMMISSIONERS:
"No Parking" sign by the In and Out Burger.
C/Fritz noted that the High School still does not
have it's "Loading Zone" signs.
AE/Liu stated that, as of this date, staff has not
received any money. However, per a phone
conversation with a member of the School District,
the money will be forthcoming.
VC/Gravdahl indicated that the Metro Disabled
Persons Bus Service went into service for the City
of Diamond Bar on September 23, 1991.
Chair/Chavers stated that, after reviewing the
draft Traffic Impact/Fee Assessment Report he has
found the following five fatal flaws in the
recommendations contained in the document: the
credits are not considered; there is no
consideration of trip length; there is no
consideration for diverted or passerby trips
(linked trips); cases 3 and 4, of the fair share
cost allocations, are unacceptable because we are
'
charging for available capacity which is not legal
under AB1600; and we cannot base an impact fee
structure on possible improvement.
February 27, 1992
Page 8
Chair/Chavers noted more flaws within the document:
because we used a needs based format, the entire
program will have to be revisited any time any
modifications are made, and therefore, it is
possible that those people who have already paid
into the program will have to be refunded by the
City; the land use types are ridiculously broad;
the cost projections are primitive; the statistical
accuracy of the model will not be able to achieve
.02; there are many mistakes in the ICU
calculations; and he questioned the veracity of the
model itself.
Chair/Chavers suggested that the Report be
reworked. He further encouraged that a Consumptive
Model Approach be used instead of a Needs Based
Format.
ITEMS FROM STAFF:CE/Mousavi reported that GPAC is finishing up their
comments on the draft General Plan. Staff will
forward a copy of the Traffic Circulation Element
to the Commission when it is available. The item
is scheduled for discussion at the April 9th
Commission meeting.
CE/Mousavi stated that three consultants have been
interviewed for the Transit Route Study. Staff is
in the process of negotiating with one of them.
CE/Mousavi reported that Diamond Bar has been asked
if we would consider Grand Ave. for the
synchronization programs that may link into Amar,
in the City of Walnut, and go westward. The item
will be on the next meeting's agenda for
discussion.
C/Fritz noted that there are cars parked on the
overpass, by the 60/57 freeway, on Grand Ave.
Deputy Clark stated that it will be looked in to.
ADJOURNMENT: Motion was made by C/Beke, seconded by VC/Gravdahl
and CARRIED UNANIMOUSLY to adjourn the meeting at
8:44 p.m.
