a City of Pleasanton o _ a Task 1.2 - Alternafives Analysis After receipt of all of the above items, KHA will prepare a traffic operation analysis of the following scenarios: Existing Baseline -existing traffic volumes, geometry, and traffic control. _ Existing plus Signal -existing traffic volumes with installation of planned troffic signal. Future Baseline -future traffic volumes, with existing geometry and Traffic control. Future plus Signal -future traffic volumes with installation of planned traffic signal. Future Altemative 1 -remove $B loop off-ramp and replace with $B diagonal off-ramp IV. Project Delivery Future Altemative 2 -remove SB loop off-ramp, replace with SB diagonal off-ramp and add eastbound Bernal Avenue to SB I-680 loop on-ramp Future Altemative 3 -retain SB loop off-ramp, add SB diagonal off-ramp and add eastbound Bernal Avenue to SB I-680 loop on-ramp for full movement interchange. The three future alternatives listed above represent our preliminary recommended alternatives and may be modified before analysis is commenced based on the kick-off meeting conducted with City Staff. KHA will analyze Traffic levels for The identified key intersections under each analysis scenario. This effort will utilize SYNCHRO traffic analysis software and will report level of service, delay, and queuing results at the I-680 southbound ramps intersection with Bernal Avenue. In addition, a review of the alternative design operations impact on the adjacent intersection of I-680 northbound ramps and Bernal Avenue will include overall corridor delay, queuing issues, and any potential conflict zones. Based on the results of the analysis, KHA will identify the preferred alternative that provides the greatest overall benefits for traffic operations and design geometries at the study intersection. Task 1.3 -Altemafives Analysis Technirnl Memorandum KHA will prepare a technical memorandum including text, tables, and figures documenting the methodology and results of our analysis and figures, which will be submitted electronically for your review and comment. The Draft Technical Memorandum will recommend one preferred alternative for further detailed study during Phase 2 of the project. Based on one set of non-conflicting comments, the results of the traffic operation analysis will be revised and finalized for submittal. Three bound copies and one unbound copy of the final technical memorandum will be submitted to the City. It is not anticipated that KHA will attend any project meetings or public hearings of this stage in the project to determine selection of fhe preferred alternative. Instead, the Final Technical Memorandum will reflect the recommended preferred alternative to be studied in further detail for geometric design feasibility in Phase 2 of the project, as reviewed and revised based on comments by City Staff. 15 ~~~ endA~aa~w' .Ne TL820087.08
