<br />to calculate these based on a comparison of weekday to Saturday intersections counts to develop <br />a ratio to apply to the model weekday forecasts. This scope and cost estimate has been prepared <br />assuming up to 24 intersections will be analyzed, as described in Task 4.2b. <br /> <br />Task 4.2e: Traffic Operations Analysis <br /> <br />The impacts of the proposed project on traffic operations will be analyzed at the study locations <br />using the 2000 HCM methods for the weekday AM and PM and Saturday peak hours for the <br />scenarios. DA will use SYNCHRO to develop the level of service at all study intersections. DA <br />will also use SimTraffic simulation model to evaluate operations of the transportation system in <br />the immediate area surrounding the project site under the 2030 with Project Buildout scenario. <br />Simulating individual vehicles will allow a more detailed analysis of project impacts in the <br />immediate vicinity of the project site. The simulated area will include Marina Boulevard <br />between Merced Street and Teagarden Street, Merced Street between Marina Boulevard and <br />Fairway Drive, and Fairway Drive between Merced Street and 1-880. <br /> <br />DA will develop AM and PM peak hour link level and intersection level forecasts for the 2009, <br />2015, and 2030 scenarios. As mentioned above, these forecasts will be adjusted based on <br />standard incremental adjustment methods to minimize model errors. Since the ACCMA <br />Countywide model does not forecast weekend conditions, Saturday forecasts will be calculated <br />based on a comparison of weekday to Saturday intersections counts to develop a ratio to apply to <br />the weekday model forecasts. <br /> <br />The demand model will be adjusted to automatically subtract existing uses that may occupy the <br />previously occupied Albertson's Distribution Center from the baseline volumes to account for <br />the demolition of the site. <br /> <br />Weekday AM and PM and Saturday peak hour service levels will be calculated at the study <br />locations including intersections, freeway mainlines, and ramp junctions. Traffic impacts will be <br />evaluated according to the standards of significance for the City of San Leandro on City <br />roadways and for Caltrans on Caltrans facilities. Using the appropriate significance criteria, <br />significant impacts will be identified. <br /> <br />DA will identify and evaluate mitigation measures that would, if possible, reduce adverse <br />transportation impacts to less-than-significant levels. These measures may include, but not be <br />limited to, roadway improvements, signalization of unsignalized intersections, enhancements of <br />pedestrian and bicycle facilities, and transportation demand management (TDM) strategies such <br />as shuttle service to and from the BART Station. As part of this scope, DA will also analyze <br />impacts at the I-880/Marina Boulevard Interchange and propose mitigations to improve <br />operations. In addition, DA will explore the extension of Aladdin Road from its current terminus <br />east to San Leandro Boulevard as a potential mitigation measure. Level of significance after <br />implementation of mitigation measures will be evaluated. <br /> <br />Consulting Services Agreement between <br />City of San Leandro and EIP Associates <br /> <br />Page 26 of 43 <br />
