02-03-2004 - Amar Road & Azusa Avenue ImprovementsCity of West Covina 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.

Sui;e 5v"9 ?arnna. California 91,353 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.

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.
