TO: Andrew G.11smant, City Manager
Memorandum
and City Council AGENDA
FROM: Shannon A. Yauchzee, Director/City Engineer ITEM NO. G-2
Public Works Department DATE February 3, 2004
SUBJECT: AMAR ROAD AND AZUSA AVENUE IMPROVEMENTS
RECOMMENDATION:
It is recommended that the City Council provide staff with direction on this matter.
DISCUSSION:
Mayor Pro-Tem Miller asked that this item be agendized for discussion. Attached is a report
from Kimley-Horn and Associates, Inc. (traffic consultant), which was completed in the year
2000. This study was done to estimate costs for traffic mitigation for the proposed BKK business
park project. The first option shows traffic mitigation for the year 2005, which involves
widening of the intersection to add turn lanes, through lanes, and bus turnouts. The second
option involves construction of an underpass so that Azusa Avenue passes under Amar Road and
is based on year 2020 traffic projections. The third option involves an at -grade intersection
widening to accommodate the year 2020 traffic projections. All options could require acquisition
and relocation of businesses on the corners. The underpass could have a significant effect on the
remaining businesses, as access is more limited.
The Kimley-Horn and Associates, Inc. study could be revised and updated to consider the three
aforementioned options. Further details and options could be developed to show the
intersections level of service with no improvements or with improvements to the year 2005 and
2020.
ALTERNATIVES:
The City Council may elect to direct staff to:
1. Retain Kimley-Horn and Associates, Inc. to update this report, study alternatives, and to
update the cost estimates. This report would cost between $5,006 and $25,000 dollars. The
report would take two to six weeks to complete.
2. Retain a consultant firm to conduct a corridor type study on Azusa Avenue and Amar Road to
evaluate long term regional options and alternatives. This study could cost several hundred
thousand dollars. This study could take up to two years to complete.
3. Receive and file this report.
FISCAL IMPACT:
The costs of alternative traffic studies are listed above. Proposition "A" funding is available in
Project No. SP-00110 "Bus Shelter Replacement" (Account No. 121.81.8009.7200) for
alternative one and could be transferred into Project No. SP-01125 "South Azusa Avenue
Capacity Enhancement" (Account No. 121.81.8111.7200) for this work.
The cost to construct any of these mitigation alternatives are listed on the attached report,
however, costs' are based on the year 2000 report. The report could be updated to reflect any
future project options and current costs. The current construction costs for these options range
from about $2,000,000 to $32,000,000 dollars.

This memorandum is intended to summarize information prepared to estimate the
probable cost of improving the intersection of Amar Road and Azusa Avenue. This
information was prepared by Kimley-Horn and Associates, Inc. for City staff to respond
to West Covina City Council questions asked at the October 51h meeting regarding the
San Jose Hills Business park project. '
At the request of City staff, opinions of probable cost were calculated for several
different improvement options for the intersection of Amar Road and Azusa Avenue.
The options considered different forecast ve: rs, improvements required for the San
Jose Hills Business park project and for longer -term, year 2020 improvements. The
year 2020 improvements considered both at -grade and grade -separated
improvements. The different improvements are described below:
Year 2005 Improvements
The year 2005 improvements were identified by Kimley-Horn during the traffic analysis
completed for the environmental document. The improvement scenarios and probabie
costs are described below.
• Background Mitigation includes the through and turn lanes identified in the traffic
study as being required to accommodate the growth in traffic without the San Jose
Hills Business Park project. The conservative opinion of probable cost for these
improvements is $1,750,000. A detailed breakdown of the cost is provided in
Attachment A.
Project Mitigation assumes traffic levels with the San Jose Hills Business Park,
and that Background Mitigation improvements are in place. The improvements
include the addition of an exclusive right -turn lane and traffic signal modification.
The -conservative opinion or probable cost for these improvements is $265,000. A
detailed breakdown of the cost is provided in Attachment A.

Year 2020 Improvements
The year 2020 improvements were identified by Kimley-Horn in consultation with City
staff as what would likely be required to accommodate future traffic levels. It should be
noted that no detailed traffic analysis has been completed to identify these
improvements. The improvement scenarios and probable costs are described below.
At -Grade improvements consisting of additional left and through lanes and
dedicated right -turn channels on all approaches. The conservative opinion of
probable cost is $12,800,000. A detailed breakdown of the cost is provided in
Attachment B.
• Grade -Separation improvement would include construction of an overhead
structure for Azusa Avenue and urban interchange ramps with full intersection
movements. This improvement would require considerable right-of-way acquisition.
The conservative opinion of probable cost -is $31,700,000. A detailed breakdown
of the cost is provided in Attachment C.
It should be noted that the cost analysis for all options considered the cost of acquiring
additional right-of-way. The right-of-way costs were based upon land value data
provided to Kimley-Horn by City staff. The land value data included the cost of the
land, damage and legal fees. Assumptions viere aiso 7- .E.de ,. ne re': of
utilities, light standards, and traffic signal modifications. The attachments to this
memorandum include unit cost assumptions, land value assumptions and line item
costs for acquiring specific existing buildings.
