selecting a preferred concept. By its nature, this task is prepared concurrent and in collaboration with the development of an access plan for the BART station. The subtasks are comprised of: 2.2.1 Conceptual Engineering Alternatives Defines, and determines geometric feasibility of, concepts for San Leandro Boulevard that reduce the number of lanes from six to four, provide on-street parking, provide corner bulb-outs at intersections at pedestrian crossings, and add segments to, or narrow the median. It examines the type of landscaping that can be provided within the median and curbside. San Leandro Boulevard will be divided into two study segments: Segment 1: between Williams Street and West Estudillo Avenue Segment 2: between West Estudillo Avenue and Davis Street Up to three (3) conceptual engineering alternatives will be prepared in 50-scale diagrams on the topographic survey of San Leandro Boulevard (to be provided by the City of San Leandro). Intersection details will be illustrated at 20-scale. The concepts will be prepared with input from the technical assessment described below. 2.2.2 Traffic and Vehicular Assessment This task conducts technical and feasibility analyses to support the design concepts developed in Task 2.2.1. These analyses are comprised of: On-Street Parking Assessment We will evaluate the proposed on-street parking on San Leandro Boulevard from Williams Street to Davis Street. It is comprised of an estimation of the number of parking spaces for each study segment, identifies where red zones or bus stops are likely to be required, and recommends time restrictions based on proposed or anticipated adjacent land uses. This task is also comprised of an estimation of the loss in vehicular capacity due to friction caused by parking maneuvers. This estimate focuses on the segment between West Estudillo Avenue and Davis Street where traffic operations are more critical. Traffic Capacity Assessment This task is part of the traffic analysis conducted in Task 2.3 (see below). It evaluates the effect of reducing the number of travel lanes from six to four, and the effect of potentially adding and/or modifying traffic or pedestrian signals. We will use Synchro software which can evaluate the effects of signal coordination, on-street parking, queuing, pedestrian signal timing, and unsignalized intersections. We will provide measures of effectiveness consisting of conventional level of service (based on delay), vehicle queuing, and corridor travel time for the AM and PM peak hours. Specific analyses are comprised of: Queuing on San Leandro Boulevard from Davis Street to West Estudillo Avenue to determine lane configuration of this segment with or without a signal and/or signalized pedestrian crossing of West Estudillo Avenue.
