Access to drilling locations will require closure of a <br /> portion of the west bound lane of Durham Ferry Road, east of South Ahern Road (Hwy 33) and <br /> west of South Koster Road. Traffic control measures will be necessary in order to ensure the <br /> safety of vehicular traffic travelling within the work zone, as well as for the safety,of the workers <br /> and other personnel on site. <br /> Figure 1 includes a vicinity map of the project site. <br /> 2.0 TRAFFIC CONTROL <br /> Personnel and Site Conditions <br /> • All workers will wear brightly colored vests (orange and/or fluorescent yellow). <br /> • All workers will undergo a safety meeting addressing traffic safety issues. <br /> • Pedestrians will be kept 25 feet from the work area. <br /> 1 Lane 2 Way Traffic Control <br /> Traffic control has been proposed in accordance with California Department of Transportation <br /> Manual on Uniform Traffic Control Devices for Streets and Highways(MUTCD). <br /> Traffic will be controlled by a flagger at each end of the work space with the easternmost flagger <br /> being designated as the coordinator. Each flagger will be given a red flag. The red flag will be <br /> given to the driver of the last vehicle proceeding into the one lane section. The driver will be <br /> instructed to give the red flag to the flagger at the other end so the opposite flagger will know <br /> that it is safe to allow traffic to move in the other direction. <br /> Signs,Barricades and Traffic Cones-Durham Ferry Road West Bound Lane Closure <br /> (Figure 2) <br /> • For traffic traveling north on South Ahern Road (Hwy 33), a ROAD WORK AHEAD (W20- <br /> 1) sign will be displayed 495 feet before the intersection of S.
