III. OLD BUSINESS:
A. Neighborhood Traffic Management Program — Presentation of proposed
action plan for five (5) districts.
SMA/Gomez presented staffs report on the Pilot Projects for the
Neighborhood Traffic Management Program (NTMP) introduced to the
residents in January 2005. Prior to that time the City was divided into five
districts to make it more manageable. For this fiscal year Council approved
$125,000 ($25,000 per district) for mitigation measures. The slide
presentation represented input received from residents during meetings
held at each of the five areas. SMA/Gomez stated that staff's
recommendation was for the Commission to concur with staff to install the
pilot projects for the five (5) NTMP districts. Once approved staff will send
out press releases to the newspapers advising residents that the projects
will commence. When the pilot projects are installed, signs will be installed
at the entrance to each of the five neighborhoods stating the area is a Pilot
Project for the NTMP.
SMA/Gomez stated that the majority of concerns from the residents in the
northern area were cut -through traffic coming off SR -57 and speeding
through the City. The same was true of Prospectors Road.
AUGUST 4, 2005 PAGE 2 T&T COMMISSION SPECIAL MEET#NG
DPW/Liu said that literally thousands of residents on a neighborhood -wide
basis were invited to attend the neighborhood meetings.
SMA/Gomez stated that the following suggestions for the westerly portion
were proposed by residents: Place red light cameras at Diamond Bar
Boulevard and Sunset Crossing Road; complete the overpass between the
SR57/60; resurface Gentle Springs Lane (to be completed this year under
CIP projects); repair sound wall near Prospectors Road and the SR60
overpass (fixed by Caltrans); extend the sound wall by an additional 80 feet.
SMA/Gomez stated that the following suggestions were offered for the
easterly area from Diamond Bar Boulevard midway into Sunset Crossing
Road just short of Prospectors Road: Install parking lanes along each side
of Sunset Crossing Road to visually narrow the road and cut down on the
speeding; install striped center medians for narrowing the street. Traveling
further west on Sunset Crossing Road toward Prospectors Road, continue
the parking lanes on both sides of the street and a painted center median.
Prospectors Road from Sunset Crossing Road south to Dry Creek Road:
install speed cushions where the grade permits. SMA/Gomez reported that
in order to consider any of the mitigation measures staff would have to
survey the roads and streets to determine location of catch basins,
driveways, etc. before speed cushions or other traffic calming devices could
be installed.
SMA/Gomez continued with the middle third of Prospectors Road: Continue
installing speed cushions where the grades and survey permit. In the final
third of Prospectors Road down to Rock River Road and the SR -60, install
speed cushions to slow traffic on the downgrade to the freeway underpass
down to Golden Springs Drive.
SMA/Gomez reported that the estimated cost to paint the striped median
and parking lanes on Sunset Crossing Road and installation of
approximately nine speed cushions would be within the $25,000 set aside
for the area. Prospectors Road is a CIP project for design of pavement
rehabilitation and it would be cost effective to include installation of the
speed cushions within the design project.
PWD/Liu responded to C/Virginkar that the proposed mitigation measures
were the result of input from the residents, consultant and staff.
SMA/Gomez stated that when the City proceeds in the future with the
NTMP, there would be a petition process that would require a 67% majority
consensus of the residents living along the affected street. However, this is
a pilot project and would be implemented without that majority process.
AUGUST 4, 2005 PAGE 3 T&T COMMISSION SPECIAL MEETING
SMA/Gomez continued with suggestions for the lower section of Sunset
Crossing Road near Diamond Bar Boulevard: Install a sign at both ends of
Sunset Crossing Road (Diamond Bar Boulevard and Golden Springs Drive)
advising drivers that they are entering a residential street and that they
should obey the laws. Parking lanes, striping and speed cushions will be
installed along the street to visually narrow the street and render it more
difficult to speed. The difference between a speed cushion and speed hump
is that a speed cushion has breaks in the center to allow for wide axle
vehicles (fire trucks, trash trucks, etc.) to move smoothly through the area.
SMA/Gomez reported the proposed measures for the center portion of
Sunset Crossing Road to Del Sol Lane: continue installing parking lanes
and striping and speed cushions where the grade permits. To complete
Sunset Crossing Road from Del Sol Lane to Golden Springs Drive, the
proposed measures are a continuation of parking lanes, striping, speed
cushion and an entry sign.
SMA/Gomez said that residents perceive cut through traffic as coming from
outside the area. Instead, it is actually their neighbors who cut through their
neighborhood from other areas. The total cost for striping, parking lanes,
speed cushions and signage was slightly in excess of $31,000 for this area.
SMA/Gomez reported on the green area — Pathfinder Road south to the
Brea Canyon Road border: Based on comments from the residents,
Fountain Springs Road has cut -through traffic coming from SR -57 at
Pathfinder Road, continuing south on Brea Canyon Road to Fountain
Springs Road. The conceptual plan for the easterly half of Fountain Springs
Road between Diamond Bar Blvd. and Castle Rock Road includes speed
cushions and narrowing of the road with Texas dots and striping. Texas
dots are approximately 6-8" in diameter and are 2 Y2 to 3" high. The most
effective and enduring material is ceramic filled with resin. The less
desirable material is a rubberized material. The street sweeper cannot go
over the Texas dot so he will lift the brushes leaving some debris in the
area. Conceptual mitigation for the westerly half of Fountain Springs Road
from Castle Rock Road to Brea Canyon includes speed cushions (beginning
at approximately Sunbright Drive). Proposed measures for Castle Rock
Road close to the Castle Elementary School and problems with congestion
during school hours are: install speed cushions to slow the traffic and
prevent U-turns; install Texas dots down the center lane to prevent U-turns.
Total cost estimated to be within the $25,000 budget.
Third Area (orange) — bounded by Diamond Bar Boulevard, Grand Avenue,
SR60 and the City's easterly boundary: Residents were concerned about
speeding along Rancheria Road and Jubilee Lane where there is no
centerline striping and no stop signs on the side streets as they enter
Rancheria Road. Residents asked for cul-de-sacs in the area. Staff intends
AUGUST 4, 2005 PAGE 4 T&T COMMISSION SPECIAL MEETING
to introduce a new traffic -calming device, the mini -traffic circle at two
locations on Rancheria Road at Casa Loma Drive and Jubilee Lane. Drivers
would be educated that all vehicles must yield to traffic on the left. On
Jubilee Lane, staff proposes the installation of speed cushions subject to
the downhill grade and continue the median with painted striping and Texas
dots at the end to further delineate the road.
The area of Golden Prados Drive on the east side of Golden Springs Drive,
was also reviewed. There are no side streets on the lower portion of
Golden Prados Drive as one proceeds toward Great Bend Drive, so staff is
suggesting speed cushions for the area subject to the downgrade.
Pink Area (the middle of the City) between Grand Avenue and Pathfinder
Road: Staff intends to key into the Maple Hill School area for the pilot
program. Further, staff recommends installation of speed cushions to slow
the traffic in front of the school on the downhill curve to Diamond Bar
Boulevard; install a raised/textured crosswalk; add red curbing in the area of
the raised crosswalk and install speed cushions on Eaglefen Drive downhill
from Birdseye Drive to Maple Hill Road. Cost estimated to be within budget.
Blue Area (northeasterly) — Brea Canyon Road/Golden Springs Drive:
Concerns — speeding and cut through traffic: Install speed cushions along
Lycoming Street on both sides of the mobile home park ingress/egress;
install raised/textured crosswalk with Texas dots at the intersection at
Glenwick Avenue and consider a new traffic circulation program in
conjunction with Walnut Elementary School.
Flintgate Drive — vacant land abutting the freeway. Staff intends to require
that traffic mitigation measures be incorporated into future commercial
construction.
SMA/Gomez reported that the residents were impressed with the proposed
Pilot projects and staff intends to stay within this year's fiscal budget amount
of $125,000. Staff chose one or two areas for pilot projects from each
district. Staff recommends that the Traffic and Transportation Commission
recommend the pilot projects to Council for approval and appropriation of
budget funds for implementation in the five NTMP Districts. Staff will provide
a manual to each Commissioner for perusal prior to the next Commission
meeting. if the project is approved, staff will begin developing articles for the
City News and develop a video for DBTV.
PWD/Liu concurred with Chair/Pincher that this has been an almost two-
year process.
C/Shah said he liked the presentation and especially liked the introduction
of the traffic circle because in many countries they work very well.
AUGUST 4, 2005 PAGE 5
T&T COMMISSION SPECIAL MEETING
Yesterday he viewed a traffic circle in Thousand Oaks and was impressed
with what he saw. it seems that there are too many speed cushions
recommended on several streets and perhaps staff would consider limiting
speed cushions to the areas near schools. He also questioned the
effectiveness of a sign that read, "please drive carefully" and felt the City
could save money by eliminating the sign. He was concerned about the
raised crosswalk and a speed cushion being in very close proximity on
Lycoming Street. in his opinion, a short median does not work well because
if drivers are not paying attention they tend to hit the median and felt the
median should be longer and wider at Lycoming Street. He liked the idea of
a textured crosswalk and believed it could work very well. He reiterated that
he was very pleased about the team's work.
C/Shay concurred that SMA/Gomez made a magnificent presentation. He
was amazed that the City could move forward with the pilot project and stay
within the budget amount of $125,000. Two major issues were cut through
traffic and speeding and he felt that the majority of mitigation measures
would help to nullify speeding. However, he did not believe that many
drivers would avoid cutting through certain areas and law enforcement
would have to be called in to help with the problem. if cut through traffic is
not eliminated, only a portion of the safety problem is eliminated. People in
a hurry that drive recklessly at the wrong time may accentuate the problem
of safety because they are out of control. He also concurred with staffs
statement that upon further evaluation the number of speed cushions could
be reduced. He asked for clarification about safety vehicles being able to
circumvent the speed cushions and wondered why a vehicle would not be
able to do the same thing. SMA/Gomez explained that the speed cushions
are broken in such a way that a wide -axle vehicle could go between the
humps whereas a smaller passenger vehicle could not circumvent the
cushion because at least one side of the vehicle would have to traverse the
cushion.
C/Virginkar complimented staff and the consultant for their great effort. He
was comfortable that the proposed mitigation measures would achieve their
intended purposes. He concurred with C/Shah's comments and concerns.
He felt that a speed cushion would not be necessary for the exit in zone 5
and perhaps all speed cushions should be eliminated from all exits. He also
felt the raised crosswalk and speed cushions were too close in proximity.
One general concern about crosswalks is that crosswalks tend to provide a
false sense of safety and by texturing the crosswalk it is further highlighted
and he was concerned that the driver might not be aware he was
approaching the crosswalk. He agreed that signs asking drivers to drive
carefully would be somewhat ineffective because the streets were filled with
too many signs. Regarding Sunset Crossing Road and the installation of a
striped center median, he wondered if it would be preferable to have a
raised island median that would send a strong signal that drivers could not
AUGUST 4, 2005 PAGE 6
T&T COMMISSION SPECIAL MEETING
cross over to the opposite side of the street. He asked why staff was not
proposing to install speed humps instead of speed cushions and whether
this was creating new criteria.
PWD/Liu explained that the use of speed humps is part of the program. In
fact, speed humps are tools (an adopted program) included in the manual
for the traffic management program. The introduction and added benefit of
speed cushions is a compromise with the County's concern about the
reduction in response time for safety vehicles. The cost is about the same
for speed cushions as it is for speed humps and the criteria is almost the
same. C/Virginkar felt that criteria should be modified to include speed
cushions. DPW/Liu responded that the City would introduce a toolbox of
measures and physical devices with this Neighborhood Traffic Management
Program for consideration. Currently, the only physical device approved by
City Council to date was speed humps. C/Virginkar asked if striping for
street parking to narrow a street had been done in other cities. DPW/Liu
said that paint has been used to strip parking in many jurisdictions. In this
case, the City is taking small steps. If the painted lines do not work staff will
move on to the next step after the six month study identifies the outcome.
C/Virginkar felt that by using Texas dots the point would be driven home
that the parking lanes were a serious mitigation measures. DPW/Liu said
that Texas dots are not pretty. Staff believes it is prudent to take small steps
and get the residents to buy into the program and support the use of
physical devices. C/Virginkar asked why staff preferred Texas dots to Botts
dots. DPW/Liu explained that Texas dots were much larger and more
difficult to traverse. CNirginkar asked if the Sheriffs Department would be
able to issue citations to drivers who ignored the parking strips and
DPW/Liu responded "absolutely" - all of the pilot projects will be supported
by the Sheriff's Department. C/Virginkar said that in his opinion the mini -
circle was a great idea and felt it could and should be used in many of the
areas throughout the City and that the mini -circle should be built up as high
as possible without obstructing views. C/Virginkar said he agreed somewhat
with C/Shah that a short median island was not effective but believed it was
more effective than Botts dots or striping and that wherever possible, the
length of the median should be extended.
Chair/Pincher asked if Sunset Crossing Road residents, upon witnessing
the effectiveness of the pilot program could ask for permanent
enhancements such as requesting median heights to be raised,
landscaped, etc. in order to make their street a gateway into the northern
end of the City. PWD/Liu responded that all requests would be considered.
In fact, residents of that area -have been expecting the City to propose some
type of traffic mitigation and beautification to solve a chronic situation.
Chair/Pincher felt that the location of Botts dots on the north side of
Fountain Springs Road off Diamond Bar Boulevard might be too close and
that the speed cushion should be moved closer to Crooked Creek Drive.
AUGUST 4, 2005 PAGE 7 T$T COMMISSION SPECIAL MEETING
SMA/Gomez said that a physical survey of the streets would be required
before the proposed measures could be instituted. For example, in the area
of concern there are commercial entries, an overpass to the storm drain
channel, fire hydrants, residential driveways, etc. that must be taken into
consideration. Chair/Pincher was concerned about the standing water in the
gutter and the possible conflicting use of Texas dots. SMA/Gomez said that
staff was aware of settling in that older area of the City and the inherent
problems with respect to street maintenance.
Chair/Pincher wondered how much the crosswalk that crossed Lycoming
Street was utilized and if there should be a more defined crosswalk across
Glenwick Avenue. SMA/Gomez said that many students cross Lycoming
Street with their parents during peak morning and afternoon school hours
and there are many who cross at Glenwick Avenue as well.
C/Shay commented that the biggest challenge facing the City is attempting
to control what amounts to too many cars. Human behavior dictates that
people look for a way to circumvent new features and typically that behavior
results in breaking the law. Therefore, it is very important for law
enforcement to buy into this equation. He was concerned that medians
could lead to new problems and he believed that the proposed mitigation
measures would have to be looked at very delicately prior to
implementation.
C/Shah suggested that stop signs in certain areas like the stop sign on
Montefino Drive might work better than speed humps. He said he liked
Texas dots for the parking lanes because it would be a cheaper solution
and prevent people from crossing over parking lanes. His opinion was that
traffic circles work and people generally respect such features and those
who break the law will do so regardless of what measures are taken. In
conclusion he asked staff to consider three options: speed cushion versus
the stop sign or number of speed cushions; installation of "please drive
safely" signs and whether or not it was cost effective, and if speed cushions
are installed close to a raised crosswalk study the area to make sure the
installations are safe. He thanked staff for a job well done.
C/Virginkar moved, C/Shay seconded to accept staffs recommendation to
install the pilot projects for the five (5) NTMP districts with the provision that
the Commissioner's comments be included in the recommendation to
Council.
SE/Alamolhoda said it was his understanding that all of the Commissioners
and residents comments and City policies were to be included in the
toolbox.
Motion carried by the following Roll Call vote:
AUGUST 4, 2005 PAGE 8 T&T COMMISSION SPECIAL MEETING

C/Virginkar expressed his enthusiasm that this program was moving
forward at a fast pace and that the residents would soon see positive action
in their community. PWD/Liu said that staff was excited about the City's
proactive approach and was very pleased with Council's support of the
program.
IV. BUSINESS: None
V. STATUS OF PREVIOUS ACTION ITEMS: None
VI. ITEMS FROM COMMISSIONERS:
C/Shah recommended that members of IT[ take this item to their next meeting. He
said he noticed that workers were walking along the edge of the medians and felt
that it presented a safety hazard. Also, when a lane is closed, the lane delineators
should start further back to better warn traffic in advance of the situation.
VII. INFORMATIONAL ITEMS:
Vlll. SCHEDULE OF FUTURE CITY EVENTS — as adgendized.
IX. FUTURE AGENDA ITEMS: None
