Tree roots caused major interruption to a water main and sewer main in the San Juan neighborhood in the City Fullerton (City), California. The City sought to address the problem as well as fix the affected asphalt concrete pavement. In addition, the City took the opportunity to make improvements to median curbs, curb and gutters, and cross gutters along seven different streets within the San Juan Community.
Cannon was selected to prepare plans, specifications, and estimates (PS&E) and construction documents for the street, water, and sewer improvements. These included pavement reconstruction, raised median reconstruction, repair of broken/damaged curbs and gutters, replacement of cross gutters and driveway aprons, and curb ramp upgrades. Cannon designed an upsized 8-inch water main and existing water services reconnection as well as the removal and replacement of an existing 8-inch verified clay pipe sewer main. Cannon conducted a design alternative analysis for various asphalt pavement rehabilitation strategies during conceptual design. Full Depth Reclamation* with cement was selected as the preferred alternative for the final design.
Cannon also provided topographic survey, utility coordination, signing and striping improvements, pre- and post-construction monumentation preservation services, and teamed with subconsultants to include geotechnical investigation and utility potholing services.
