ENG APPROVAL OF PLANS AND SPECIFICATIONS AND AUTHORIZATION TO ADVERTISE TO RECEIVE BIDS FOR NORTH BATIQUITOS INTERCEPTOR SEWER MANHOLE REHABILITATION, PROJECT NO. 3538 DEPT. HEAD ]^TJ CITYATTY. . (gz>~ CITY MGR. JQ^ RECOMMENDED ACTION: Adopt Resolution No.2009-069 approving plans and specifications and authorizing the City Clerk to advertise to receive bids 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 Dr, 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 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. City staff has prepared plans and specifications for the rehabilitation of 41 existing manholes on the North Batiquitos Interceptor Sewer and the project drawings and contract documents are on file in the Public Works-Engineering Department. The manhole improvements are consistent with recommendation in the City's 2003 Sewer Master Plan. Staff recommends approving the plans and specifications and authorizing the City Clerk to advertise for bids for the North Batiquitos Interceptor Sewer Manhole Rehabilitation, Project No. 3538.
