Detailed geometric studies, topographic surveys, and final construction <br />documents were prepared by Huitt-Zollars for this $5 million project to add one <br />through lane in each direction on Oso Parkway, right -turn -only lanes in each <br />direction on Marguerite Parkway, and create double left -turn lanes in all four <br />directions of the existing arterial highway intersection. Raised medians on all <br />four legs of the intersection were completely reconfigured. Design constraints <br />included access to existing developments, an adjacent hillside slope buttress, <br />major water pressure reducing station, and other utility vaults and facilities. This <br />project affected 4,600 linear feet of highway, three signalized intersections, and <br />included 1,700 linear feet of retaining walls. Construction plans, specifications, and estimates were prepared <br />for this $5 million project. The work of subconsultants for environmental documentation, traffic engineering, <br />landscape architecture, and cost estimating was coordinated by Huitt-Zollars. This project involved relocation of <br />numerous electrical, telephone, cable and gas utility facilities, and reinforcement of the underground vault for the <br />pressure reducing station.

The $2 million <br />project's purpose was to improve the capacity of this intersection to <br />accommodate increased traffic resulting from continued new residential <br />development throughout the region. Capacity improvements at the <br />intersection were as follows: <br />Antonio Parkway: Addition of a fourth southbound thru lane <br />and a third northbound left -turn lane onto Oso Parkway <br />Oso Parkway: Addition of a fourth eastbound thru lane <br />CLIENT CONTACT: <br />OC Public Works <br />Steve Soo - Project Manager <br />300 N.
