VC/Pincher said she thought that a bill had passed the Assembly that would allow
street sweepers to have cameras for enforcement in 2011. PWD/Liu shared that
Request for Proposals (RFP's) have been distributed for street sweeping services and
are due by February 15th . One optional item under consideration is this automated
parking enforcement tool. The language of the bill refers to "public agency owned or
public agency operated street sweepers" that can have this tool to provide parking
FEBRUARY 10, 2011 PAGE 2 T&T COMMISSION
enforcement on street sweeping days. There are many questions to be answered
before D.B. implements such a tool. VC/Pincher asked if this service would eliminate
a compliance officer position. PWD/Liu responded that the system, if implemented,
would supplement the regular service because there is currently only one CSO
position.
IV. OLD BUSINESS: None
V. NEW BUSINESS: None
VI. STATUS OF PREVIOUS ACTION ITEMS: None
ITEMS FROM COMMISSIONERS:
C/Mok said he received a call from a resident who told him the green was short -
cycling at the northbound SR -57 off -ramp traffic signal at Pathfinder Road.
AE/Malpica-Perez responded that staff received several calls about the signal. He
was able to pass on the information to Caltrans and the issue was resolved
yesterday.
C/Carrera asked if staff is alerted to system problems only when residents call in or if
there is some kind of diagnostics that alerts staff. SENee responded that there are
two answers to the question depending on who owns the signal. If Caltrans owns and
maintains the signal, generally, they are notified about the problem. If the City owns
and maintains the signal, there is not necessarily an alarm about the problem
because there are certain parameters that need to be refined and set up to detect
such problems. Staff is typically alerted regarding traffic signals that are in red flash
mode. C/Carrera said that residents should be encouraged to notify staff with any
and all concerns.
Chair/House recalled at the last meeting that there was discussion regarding signage
on Pathfinder Road next to DBHS reflecting school speed zone. He shared that he
did not observe any signage on Pathfinder Road. AE/Malpica-Perez responded that
there is a "25 mph when children are present" sign by the Chevron gas station and a
second sign by the school on Brea Canyon Road. The 40 mph sign is posted after
the 25 mph sign (a white and yellow sign). He was not sure if there was a 25 mph
sign on Pathfinder Road. PWD/Liu said that staff would have to check about whether
a sign is required on Pathfinder Road.
VII. INFORMATIONAL ITEMS:
A. Traffic Signal Battery Backup System Project—AE/Malpica-Perez reported
that staff continues to work with the manufacturer and the City's IS Department
to set up the paging and alarm system. The design and construction
management contract was approved by the City Council on February 1s�. Staff
expects the design to be completed by early April and completion of
construction is anticipated by the end of June.
FEBRUARY 10, 2011 PAGE 3 T&T COMMISSION
( B. Multi -Year CIP — Comprehensive Infrastructure Management Plan — SE
Yee stated that about six months ago, the City engaged a consultant to assist
the City in developing a multi-year planning document that would look at the
City's sewer and storm drain infrastructure. They also assessed the inventory
and condition of the facilities in order to develop cost valuations and future
projects with respect to on-going costs to maintain and potentially rehabilitate
some of the infrastructure.
C. Industry's Grand Avenue Bridge Widening/Interchange Project— SE/Yee
reported that a funding application was initiated by the City of Industry to seek
funding from Metro for a portion of the project that lies within the City of D.B. at
the intersection of Grand Avenue and Golden Springs Drive. The project is to
improve the intersection by adding through lanes on Grand Avenue and
additional turn lanes on Golden Springs Drive. Stated costs for the
improvements is $15 million. The funding application requested $6 million with
the balance of the project costs to be paid by the City of Industry.
D. SR57/60 Feasibility Study — SE/Yee explained that staff members and
Council Members will visit Washington D.C. in March to gain visibility and
lobby for funding for the overall "big fix" improvement for the interchange. The
underlying goal is to be able to get this project listed on the re -authorization of
a Federal Transportation Bill.
E. Environmental Enhancement Mitigation (EEM) Improvement Project —
SE/Yee reported that this project was completed when plantings were installed
about a week and a half ago on Brea Canyon Road and Via Sorella.
F. NTMP — Briar Creek Road/Decorah Road Neighborhood/Willow Creek
Neighborhood — SE/Yee stated that staff plans to bring the concept back to
the neighborhood the first part of March. At that time, staff will request the
neighborhood to seek two-thirds approval of the residents along Willow Creek
in order to move forward with final plans for the project.
G. Lemon Avenue On/Off-Ramp Project — AE/Molina reported that staff
anticipated final plans and specs would be completed by the end of January.
However, due to staffing changes by the design consultant, plans are now
expected to be completed by the end of February for submission to Caltrans.
The right-of-way co-op agreement, the agreement to be executed between the
City and the State that would allow the State to go in and do the partial right-of-
way takes for the project, is the next step in the process. Staff is waiting for
the State to provide the fourth draft of the co-op agreement for City Attorney
review and presentation to Council. ,Staff hopes to have the draft agreement
by the end of February so that the matter can be scheduled for Council
agenda in March. Once the document is executed, the anticipated 18 -month
process will commence immediately with start of construction projected by the
end of 2012/beginning 2013.
H. Residential Area 7/Zone 5 Road Maintenance Project — AE/Molina stated
that yesterday, the consultant advised staff that they had been in the targeted
neighborhood conducting field investigation of the existing pavement
conditions. Preliminarily, the feedback is that the roadways appear to be in
fairly good shape. The final design scheme and repair recommendations will
be presented to staff by the end of February for bid opening by the end of
March/early April.
FEBRUARY 10, 2011 PAGE 4 T&T COMMISSION
I. Brea Canyon Road Drainage Improvement Project —AE/Molina indicated
that this project was completed this week. Three catch basins were
reconstructed along the east side of Brea Canyon Road, north of Pathfinder
Road.
J. 2010-2011 CDBG Curb Ramp Project—AE/Molina reported that this project
was awarded to CJ Construction and construction has commenced with an
average curb ramp completion of 20 per week. As required, the project is
scheduled to be completed by the end of February.
PWD/Liu reported that at its February 1, 2011 meeting, the City Council approved
Ordinance No. 01(2011), the updated Citywide Speed Zone Survey Study.
PWD/Liu stated that staff has been working with Caltrans since 2003 to get signal
improvements on the southbound SR- 57 off -ramp at Brea Canyon Cutoff Road. D.B.
completed its portion of the design work. The project went to bid two weeks ago and
received 13 proposals. Staff will recommend to the City Council to award the contract
to Freeway Electric and, if approved, signal construction will commence in March with
completion anticipated by the end of June.
IX. SCHEDULE OF FUTURE CITY EVENTS: As stated in the agenda.
ADJOURNMENT: There being no further business to come before the Traffic and
Transportation Commission, Chair/House adjourned the meeting at 7:40 p.m.

CITY OF DIAMOND BAR
TRAFFIC AND TRANSPORTATION COMMISSION
MEMORANDUM
DATE: February 28, 2011
MEETING DATE: April 14, 2011
TO: Chair and Members of the Traffic and Transportation Commission
VIA: David G. Liu, Director of Public Works/City Engineer
FROM: Kimberly Molina, Associate Engineer,bU
SUBJECT: Cleghorn Drive/Gold Nugget Avenue Neighborhood Traffic Management
Program Update
BACKGROUND/DISCUSSION:
In August of 2008 the City received a request to install speed cushions along Cleghorn
Drive due to concerns with speeding along the roadway. In accordance with the
Neighborhood Traffic Management Program (NTMP) guidelines a petition/request from
51% or 115 households within the Cleghorn Drive neighborhood was needed to begin
the NTMP. The initial requestor was able to obtain the 51% required and the NTMP
process began. The program was introduced to the neighborhood on February 19,
2009 in which approximately 10 residents were present. At that meeting it was decided
by those in attendance that Cleghorn Drive and Gold Nugget Ave. should be included in
the study for potential traffic calming devices. The neighborhood that was included in
the study is shown as Exhibit A-2 as well as the locations where staff collected speed
and volume data.
Traffic speed and volume Counts were collected in February 2009 over a three-day
period (Friday through Sunday) which indicated some speeding and volume issues
along Cleghorn Drive and Gold Nugget Ave. (Refer to Exhibits A-1 & A-2 which
identifies the locations of the counts as well as the February 2009 speed and volume
counts in orange.) Cleghorn Drive and Gold Nugget Avenue is a residential roadway
with a 25 MPH speed limit. Counts indicated an average 85 percentile speed between
30 and 35 MPH.
On August 6, 2009 staff held the second meeting for the neighborhood, however no one
was present. The meeting was rescheduled to September 9, 2009 during a regularly
schedule Traffic and Transportation Commission Meeting where the results of the
speed and volume counts as well as a conceptual plan of devices proposed to be
installed within the neighborhood were presented. Approximately 3 residents were in
attendance at the rescheduled second meeting. A two -phased approach was
developed which identified Phase I (refer to Exhibit B) as an educational outreach effort.
Additional signage (i.e. speed limit signage and speeding awareness signage) was
installed as well as education flyers that were mailed out to the entire neighborhood
informing the residents of the program. Phase II was identified as the actual installation
( of the traffic calming tools that were identified for the neighborhood. After discussion of
the proposed concept with those in attendance a petition was re -circulated through the
neighborhood, by the "team captains" to obtain the required 67% in favor of proceeding
with the Phase II plans, specifications and estimates (PS&E package) of the traffic
calming concept. Of the 273 parcels that are within the neighborhood, 183 parcels was
required to meet the 67% in favor of proceeding to the Phase II process in the NTMP.
Final signatures from 165 lots were obtained for a total of 60% in favor with proceeding
with the PS&E package of the concept plan.
While the required 67% was not obtained, staff believed that a clear majority of the
residents directly along the roadways where the tools were being proposed to be
installed was obtained (70% approval along Gold Nugget and 56% along Cleghorn
Drive) and therefore staff recommended moving forward with construction of the
proposed traffic calming tools.
Staff began design of the final plans in September 2009 which were presented at a third
meeting with the neighborhood in January 2010. These plans identified the locations of
the speed cushions, as well as red curb and stop sign installation there were to be
constructed as shown in Exhibit C. With the resident's support of the final design, a
construction contract was awarded in April 2010 and construction of the traffic calming
tools was completed in June 2010.
To determine the effectiveness of the traffic calming measures, a follow-up set of speed
and volume counts are collected 6 months after the construction was completed. Due
to the fact that the 6 -month counts for this neighborhood would have been collected in
December when traffic patterns are varied from "normal" patterns due to the Holiday
Season, the 6 -month follow-up counts were collected in January 2011.
Staff was pleased to find that the results are extremely favorable. The data indicates
that volume and the 85 percentile speed have decreased by as much as 296 vehicles
and 10 mph along Cleghorn Drive. Additionally, the volume and the 85 percentile speed
have decreased by as much as 113 vehicles and 11 mph along Gold Nugget Avenue.
(Refer to Volume and Speed differences as shown in green on Exhibit A).
The greatest concern of speeding and cut -through traffic, as indicated by the residents
at the meetings, was along Cleghorn Drive and while speeding was a concern for the
residents along Gold Nugget Avenue.
Overall, the 6 -month follow up traffic data indicates that the traffic calming measures
that were designed and installed within the Cleghorn Drive/Gold Nugget Avenue
Neighborhood have been effective at slowing down overall traffic within the
neighborhood and in many cases have been able to deter cut -through traffic from
traveling along the residential roadways.
RECOMMENDATION:
It is recommended that the Traffic and Transportation Commission receive and file the
report by staff regarding the results of the Cleghorn Drive/Gold Nugget Avenue
Neighborhood Traffic Management Program.
