Meeting Date:April 25, 2017 To:President and Board Members From:Kevin Crawford, Executive Manager Staff Contact:Lindsey Stephenson, Associate Engineer Lindsey.Stephenson@carlsbadca.gov Subject:Adopt a Resolution approving plans and specifications and authorizing the Secretary to the Board to advertise and receive bids for the La Costa Water Main Replacement, Project No. 5035. Recommended Action Adopt a Resolution approving plans and specifications and authorizing the Secretary to the Board to advertise and receive bids for the La Costa Water Main Replacement, Project No. 5035. Executive Summary In 2013,a pipeline failed within the south golf course of the Omni La Costa Resort. The existing asbestos cement pipeline, constructed in 1961,has reached the end of its useful life and is in need of replacement. Approximately 580 linear feet of new pipeline is proposed to be constructed by horizontal directional drilling (HDD) to minimize damage to the existing golf course. The remaining 390 linear feet will be standard open -cut construction. Additionally, two nearby waterline segments within limited access easements are also recommended to be replaced by a single pipeline. Service to customers will be maintained during construction. Staff recommends approval of the project plans and specifications, and authorization to advertise and receive construction bids for Project No. 5035. Discussion In 2013, an asbestos cement pipeline failed within the south golf course of the Omni La Costa Resort and has since been out of service while a new alignment was negotiated with the property owner.In order to mitigate future line -breaks including water loss,interruption of service, and property damage, staff recommends replacement of the old pipeline and a new alignment. The revised alignment allows easier access for maintenance and operations staff. The construction will include approximately 970 linear feet of 8-inch PVC waterlines crossing the south golf course and connection to the existing potable water distribution system adjacent to a condominium complex at 2500 Navarra Drive (2500 Navarra Drive Homeowners' Association). To minimize impacts to the golf course, approximately 580 linear feet of water line will be constructed using a trenchless construction method. The remaining 390 linear feet to connect to the condominium complex will be completed with standard open -cut construction. Item #10 April 25, 2017 Page 1 of 5 In addition, approximately 90 linear feet of new 8-inch waterline will be installed at 2522 Navarra Drive (La Costa Riviera Homeowners' Association) to provide a more reliable service to those customers and allow easier access for maintenance and operations staff. The current alignment is located between units in a very narrow easement which makes maintenance difficult.
