ENG ACCEPTING BIDS AND AWARD OF CONTRACT TO SANCON ENGINEERING INC. FOR NORTH BATIQUITOS INTERCEPTOR SEWER MANHOLE REHABILITATION, PROJECT NO. 3538 DEPT. HEAD 1^1",T CITYATTY. jfcj^_ CITY MGR. / i/L RECOMMENDED ACTION: Adopt Resolution No. 2009-188 accepting bids and award of contract to Sancon Engineering Inc. for the North Batiquitos Interceptor Sewer Manhole Rehabilitation, Project No. 3538. ITEM EXPLANATION: The North Batiquitos Interceptor Sewer (NBIS) is divided into reaches NB1 through NB9 and begins near the north shore of the Batiquitos Lagoon at Columbine Drive, just west of El Camino Real. From that beginning point the NBIS pipeline alignment continues westerly along the north shore of the lagoon to the North Batiquitos Lift Station, located near Gabiano Lane. From the lift station the alignment goes northwesterly under Interstate 5 and continues north to the Encina Water Pollution Control Facility. The NBIS was constructed in the early and mid 1970s, with the final upper reaches being completed in 1976. This manhole rehabilitation project includes reaches NB1 through NB4 of the NBIS, a 1.9 mile long section of the sewer that follows the north shoreline of the lagoon between El Camino Real and Gabiano Lane. Much of the alignment is in or near a public trail with the remaining portions of the alignment traversing the Four Seasons Resort golf course, agricultural property and property owned by the Batiquitos Lagoon Foundation. During its most recent cleaning and inspection, the pipeline in reaches NB1 through NB4 was found to be in good condition. However, 41 manholes in this alignment were found to be severely corroded with considerable ground water infiltration present, and therefore in need of replacement or rehabilitation. In consideration of the sewer's sensitive location, specific methods of trenchless rehabilitation have been selected. Manholes will be rehabilitated without excavation, using low impact work methods designed to eliminate direct impacts to the surrounding habitat. In order to anticipate and minimize any impacts the project could have on the properties, City staff corresponded with the Aviara Masters Association, Four Seasons Resort, State of California, and Batiquitos Lagoon Foundation during the design phase of the project. Since much of the alignment is on or near the public trail and the resort golf course, a continued effort will be made to coordinate construction activities in an effort to minimize any inconveniences to the users of the properties during the construction phase. On April 14, 2009, through the adoption of Resolution No. 2009-069, the Carlsbad City Council approved plans and specifications and authorized the City Clerk to advertise to receive bids for the North Batiquitos Interceptor Sewer Manhole Rehabilitation, Project No. 3538. On June 25, 2009, two (2) sealed bids were received for the construction of this project, which are summarized in the table below: '<" "-..•'"•;... GQftOTtACTQR 1. Sancon Engineering Inc. 2.

ENVIRONMENTAL IMPACT: A Coastal Development Permit (CDP 07-13), Mitigated Negative Declaration (MND) and Mitigation Monitoring and Reporting Program (MMRP) were prepared for the Batiquitos Interceptor Sewer Rehabilitation Project pursuant to the California Environmental Quality Act (CEQA). The initial study (EIA Part II) prepared in conjunction with the project identified potentially significant effects on the environment with respect to biology and hydrology/water quality. However, mitigation measures have been employed, which reduce those effects to a less than significant level. Planning Commission Resolutions 6463 and 6464 approving the CDP, MND and MMRP were approved by the Planning Commission on September 17, 2008. No further environmental review is required.
