BACKGROUND The proposed traffic signal at West Las Positas Boulevard and Muirwood Drive is identified in the City's General Plan. The intersection is also identified as a high priority in the City's Traffic Signal Priority List and is necessary to mitigate school related traffic congestion during the morning and afternoon peak hours. The project will replace the existing all way stop signs with a traffic signal, which includes all required traffic signal equipment, traffic signal interconnect equipment, and miscellaneous signing and striping. This project will also reduce the size of the intersection, improving approaching sight distance, pedestrian access, bicycle circulation, and intersection operations. The proposed intersection improvements at Stoneridge Drive and Stoneridge Mall Road will reconstruct the existing northeast curb and sidewalk, allowing the existing third westbound through lane to be converted to a shared through /right turn lane. These improvements are required as part of an existing agreement between the City and BART to mitigate impacts from the recently opened West Dublin BART Station. DISCUSSION Bids Sealed bids for this traffic signal installation project were opened on March 16, 2011. There were seven (7) bids received ranging between $456,577 and $543,000. The apparent low bid was 16% lower than the engineer's estimate of $544,000 (see Attachment 3 for Bid Summary). Past work performed by Tim Paxin's Pacific Excavation, Inc. was verified to be satisfactory.
