Recommended Action Adopt a Resolution approving plans and specifications and authorizing the secretary to the Board of the Carlsbad Municipal Water District (CMWD) to advertise and receive bids for the Valve Replacement: Phase I, Project No. 5019-A. Executive Summary The repair or replacement of inoperable valves is an integral component of a well-managed water distribution system. CMWD's Water Valve Repair/Replacement Program (Program) provides reliable water delivery, helps to maintain high service levels to customers, and also reduces water loss. CMWD has initiated this Program to repair or replace broken valves throughout the system. Phase I of the multi-year Program will install 52 valves at 19 prioritized locations throughout the CMWD service area. Staff recommends that the Board approve the plans and specifications and authorize the secretary to the Board to advertise and receive bids for the Valve Replacement: Phase I, Project No. 5019-A (Project). Discussion CMWD is focused on managing assets to maintain high service levels. CMWD has developed the Program to protect these assets, including the repair or replacement of valves determined to be inoperable during routine maintenance or operations. The Program is a multi-year capital improvement project known as the Water Valve Repair/Replacement Program (CIP No. 5019) to renew the broken valves identified. CMWD has prioritized the replacement of broken valves throughout the system based on the anticipated consequence of failure for that valve. A valve is determined to have a high consequence of failure if the loss of that.valve would be most detrimental, such as valves in close proximity to critical public service facilities, major transportation routes, major transmission lines, or sensitive environmental areas. This first phase of the Program, known as Valve Replacement: Phase I, Project No. 5019-A (Project) will replace broken valves at 19 prioritized locations throughout the CMWD service area. Subsequent phases will replace other broken valves. Page 445 Excavation to replace these broken valves will have associated costs and may be disruptive, so CMWD has assessed other improvements that could be made concurrently. In addition to replacing the broken valves, CMWD is replacing any valves that are on the same fitting as the broken valve and are of the same vintage. If the location of the broken valve could benefit from additional valves on the same fitting to provide better system control, CMWD would install new valves, as needed. Within the Project, 52 new valves will be installed at 19 key locations, categorized in the following table. The 19 key locations are distributed throughout the CMWD service area and are shown in Exhibit 2, with the majority in the northern portion of the city. Future phases of the Program will focus on more specific zones within the CMWD service area. VALVES TO BE INSTALLED UNDER VALVE REPLACEMENT: PHASE I, PROJECT NO. 5019-A Broken va lves to be replaced 19 Existing valves adjacent to broken valves and of similar vintage to be replaced 19 New valves to be installed to improve system operations 14 TOTAL VALVES TO BE INSTALLED 52 CMWD is also embarking on an innovative Condition Assessment Program to better characterize the state of existing water pipelines. A final component of the Project will be to complete condition assessment on the existing pipes while the pipes are exposed for the valve replacement work. While the valves are being replaced, a sample of the adjacent pipe will be removed from the pipe and the condition will be assessed. The information gathered through this effort will help CMWD prioritize future pipeline maintenance and improvements. The construction contract for the Project will contain general performance standards, technical specifications, sequencing and notification requirements to minimize disruptions, and a one year warranty period. Retention will be withheld from each progress payment until final acceptance of the Project. The anticipated construction duration is approximately one year, and the construction contract includes liquidated damages which may be assessed for each day in excess of the time specified for completion of the work. Fiscal Analysis The engineer's estimate of the construction cost ofthe Project is $1,600,000. The total project cost of $2,275,000 includes: construction contract; contingency for change orders management; construction management and inspection; and engineering and administrative support for contractor shop drawings, requests for information, meetings, and community outreach. In addition to the construction contract, an estimated $75,000 from the Water Condition Assessment Program (CIP No. 5051) will be used to conduct condition assessment on the existing pipes that are immediately adjacent to the valves being replaced. Page 446 The Project will be funded by the Water Valve Repair/Replacement Program (CIP No. 5019), with the condition assessment work being funded by the Water Condition Assessment Program (CIP No. 5051).

Environmental Evaluation (CEQA) This Project is exempt from California Environmental Quality Act (CEQA) review pursuant to CEQA Guidelines Section 15302(c) -replacement or reconstruction of an existing utility system and/or facility involving negligible or no expansion of capacity. Page 447 Public Notification This item was noticed in accordance with the Ralph M. Brown Act and was available for public viewing and review at least 72 hours prior to the scheduled meeting date. This Project will result in short-term water service disruptions at each of the 19 locations when the new valves are installed. Construction at some of the locations will also disrupt traffic and access. CMWD staff will complete public outreach within the vicinity of each valve replacement site for general notification of upcoming construction, as well as properly notify customers of any water service interruptions or traffic/access impacts during construction.
