Contra Costa Boulevard Improvements

Project Summary
The Contra Costa Boulevard (CCB) Improvement Project (Viking Drive to Chilpancingo Parkway) is a large, multi-phased public works project along CCB with numerous construction elements, including roadway excavation, pavement overlay, intersection geometry modification, new median alignments, new curb/gutter alignments, concrete sidewalk installation, traffic signal replacement, street lighting installation, and streetscape/landscape enhancements.  The project limit extends from the CCB/Chilpancingo Parkway intersection south to approximately 200 feet south of the CCB/Viking Drive intersection.  The existing traffic signal at CCB/Golf Club Road and CCB/Viking Drive intersection will be replaced, and a second northbound left turn pocket will be added at the CCB/Golf Club Road intersection.  Approximately 36 existing trees that are currently in conflict with the proposed project improvements along the west side of CCB and along the existing median island will be removed as part of the project work.  Project construction near the business districts will take place at night to minimize the impact to traffic flow along CCB and the adjacent businesses.  Project construction near the residential neighborhoods will take place during the day to reduce nighttime noise impact to the adjacent property owners.

The CCB Improvement Project is funded by a number of Federal and County transportation grants, including $1,183,000 in Federal Highway Safety grant and $1,249,000 in countywide Measure J.  The remaining project cost is funded with local funds.  The total project construction is estimated to cost $4,473,917.

The CCB Improvement Project consists of three phases of work that will be constructed separately.  The first work phase consists of the construction of all concrete and electrical improvements, and all subsurface landscape components (e.g. irrigation, piping, and dirt placement).  The second work phase consists of pavement resurfacing/repair work, colored crosswalk treatment, and final pavement striping.  The third work phase consists of the installation of above ground streetscape improvements (e.g. final planting, mulch placement, and street furniture).  The CCB Improvement Project is estimated to be completed in the fall of 2014.  The general contractor for the project construction is Ghilotti Brothers Inc.

Park Engineering, Inc. has been hired by the City to perform construction management, project coordination, and public outreach for the project.  For all project related questions or concerns, please contact Jaemin Park (
