CHy of Santa Ana <br />On -Call Traffic Engineering <br />be drawn using fine dashed lines. Existing striping will be shown on the design <br />plans to help to identify removal quantities, lane alignments and join locations. <br />Construction area traffic control plans will be prepared showing two street <br />segments per sheet. The designs will isolate the construction area from vehicle <br />travel lanes. Guidelines for lane closure, lane drop transitions, barricades, <br />delineation and signing would be based on the City's preferred reference. <br />Typically, the "WATCH" or "Caltrans Manual", or the "Work Area Protection and <br />Traffic Control Manual" will be used. All three references are generally based on <br />similar factors, such as approach vehicle speed entering the work area. <br />Available lane widths and appropriate buffer areas between travel lanes and <br />work areas or trenches are critical design. factors, along with transition tapers. <br />Traffic control drawings would be supplemented with notes and details as <br />needed to clearly define the intended vehicle management. It is expected that <br />larger construction projects will be phased for the purpose of maintaining vehicle <br />flow through the work area at all times. Notes and details will be provided for <br />maintained access to local business and residential areas. Areas where major <br />construction will interfere with high vehicle volumes may require nighttime <br />construction. Work schedules will be clearly defined on the traffic management <br />plans. <br />Schedule of Work <br />Below is a schedule showing the approximate hours for each personnel category <br />for the tasks listed in Attachment A (for grant application schedule, see "B. <br />Preparation of Grant Applications"). <br />NEW TRAFFIC SIGNAL <br />DESIGN AND DRAFT PLANS <br />PRINCIPAL ENGINEER <br />1 <br />REGISTERED ENGINEER <br />g <br />ASST.
