This fast-track design included a feasibility study, design report, geotechnical investigation, RWQCB permitting, DOHS approval, CEQA documentation and permitting with Caltrans and the Flood Control District. DBE provided all of the listed services for this design, which included 10,000 LF of 8-inch through 30-inch diameter PVC recycled water pipeline, two (2) bridge crossings, retrofitting a soccer complex, groundwater replenishment basins and irrigation systems at a health care facility.

CANNON ROAD 24-INCH RECYCLED WATER MAIN
Carlsbad Municipal Water District
Carlsbad, CA

Design of this 24-inch diameter recycled water main included coordination and permitting with Caltrans for crossing under the I-5 freeway and traversing the freeway on and off ramps. Additionally, poor soil conditions required special design considerations and providing for support of existing utilities both parallel and perpendicular to the alignment. The pipe material selected for the 2,600 LF reach was cement mortar-lined and coated steel with a ductile iron alternate bid option. Other issues in the design were a deep storm drain crossing, special connections at each end and a connection for the freeway irrigation system.

BAKE PARKWAY RECYCLED WATER PIPELINE
Irvine Ranch Water District
Irvine, CA

Project consists of 4,060 LF of 12-inch diameter and 5,020 LF of 24-inch diameter PVC recycled water pipeline. DBE was responsible for all services from aerial topography and alignment study through construction support. A portion of the pipeline was constructed within an existing 700-foot-long Caltrans bridge spanning the I-5 freeway. A geotechnical investigation was provided, as was potholing of critical existing utilities. Provided services also included all coordination and permitting with Caltrans, City of Irvine and City of Lake Forest.
