Executive Summary The Project will construct approximately 4,400 linear feet of 8-inch diameter polyvinyl chloride water pipeline to replace aging asbestos concrete pipelines serving five residential areas and one business area within the City of Carlsbad. The Carlsbad Municipal Water District Board approval of these plans, specifications and contract documents is required under Carlsbad Municipal Code Section 3.28.080(E) because the expected value for this work is greater than $200,000. The construction cost estimate for the project, including contingency funds, is $3,615,000, and therefore is subject to this requirement. Staff recommend that the CMWD Board approve the plans, specifications and contract documents, and authorize the Secretary of the Board of Directors to advertise and receive project bids. Discussion The project will replace approximately 4,400 linear feet of aging asbestos concrete pipe with PVC pipe in six noncontiguous locations in the city: • Approximately 440 linear feet of pipe will be replaced in the State Street alley, between Grand Avenue and Carlsbad Village Drive, which serve 11 business customers • Approximately 530 linear feet of pipe will be replaced on Juniper Avenue, between Carlsbad Boulevard and Garfield Street, which serve the residents on this street June 21, 2022 Item #7 Page 1 of 11 MUNICIIPAL WATER D IISTRIC'f Staff Report • Approximately 530 linear feet of pipe will be replaced on Hemlock Avenue, between Carlsbad Boulevard and Garfield Street, which serve the residents on this street • Approximately 900 linear feet of pipe will be replaced on Garfield Street, between Chinquapin Avenue and the southern terminus of the street, which serve the residents on this street and the Hubbs Sea World Research facility • Approximately 800 linear feet of pipe will be replaced on Tierra del Oro Street, which serve the residents on this street • Approximately 1,200 linear feet of pipe will be replaced on Shore Drive, which serve the residents on this street Pipes will be upsized to 8 inches in diameter to meet current fire flow requirements and CMWD’s engineering standards. New, generally parallel, alignments were designed for four of the six locations. Construction in parallel alignments will allow existing water services to remain active during construction and limit residential shutdowns. After services are reconnected and the new lines are operational, the existing pipelines will be abandoned in place in accordance with CMWD’s engineering standards. The two locations where pipelines will not be constructed in parallel alignments are: • State Street alley, between Grand Avenue and Carlsbad Village Drive, where the new pipe will be replaced in the current alignment due to existing utility constraints. Prior to construction, a temporary highline will be installed to serve all State Street alley water customers during construction. Highlining the water services will provide the businesses with water service throughout construction operations and limit service interruptions. The existing water line will then be removed, and the new main will be constructed in the existing alignment. • Tierra del Oro Street, where the existing water main is looped around the street and private improvements have encroached over the water main. The new straight pipeline alignment will conform to CMWD engineering standards, facilitate future maintenance and avoid future breaks due to private improvement construction. The existing water line will remain in service during construction to minimize residential service disruptions. After services are connected and the new line is operational, the existing looped pipe will then be abandoned in place on keeping with CMWD’s engineering standards. Phased construction is planned to minimize disruption of water service to the residents and businesses served. CMWD staff are working with the Communication & Engagement Department to reach out in advance of the project to meet with, notify and coordinate with the businesses and residents that will be temporarily impacted during these facility improvements. Parking and delivery access for the State Street alley businesses will be addressed during pre- construction meetings with the contractors, based on input received during outreach meetings. Appropriate city and CMWD staff coordinated during project design, given their previous experience working in these areas. City staff have a good working history with the business communities in the Carlsbad Village and will maintain these relationships despite temporary disruptions that will ultimately improve their business operations. Affected customers will be provided with updates on the schedule of work. Residents will also receive multiple notifications prior to, during and following construction. Residential street parking will be June 21, 2022 Item #7 Page 2 of 11 temporarily impacted during these improvements to the residents’ water lines. Contract documents specify daily restoration of access to the areas. Additionally, project phasing will respect and incorporate schedules of various city community events planned in these areas, such as the annual Carlsbad Marathon and the weekly farmer’s market. Staff have incorporated known major city events into the contract specifications indicating restrictions on work schedules prior to and during these events. CMWD coordinated with the Transportation Department in their planned repaving of Tierra Del Oro Street and Shore Drive. Paving projects on these streets will now occur after the new water lines are installed. Paving for all other segments will be done in accordance with CMWD engineering standards for trench repaving. Options Staff provide the following options for the CMWD Board’s consideration: 1. Adopt a resolution approving the plans, specifications and contract documents for the project and authorizing the Secretary of the Board of Directors to advertise for bids for the Downtown and Terramar Water Main Replacement, Capital Improvement Program Project No. 3904-C. Pros • Provides capacity to meet fire flow water demands • Reduces risk associated with potential pipe breaks and emergency repairs Cons • Work will temporarily disrupt water service during connections to highline in the State Street alley and final reconnections of water services in all locations • Work will temporarily disrupt traffic and parking during daily construction working hours, but will be restored at the end of the day for access and parking 2. Do not adopt a resolution approving the plans, specifications and contract documents for the project Pros • None identified Cons • Delays project advertisement for construction bids, selection of contractor and start of construction • Increases risk of pipe leaks or breaks and emergency construction • Potential increase in construction costs due to delay in awarding construction contract Staff recommend Option 1 for the CMWD Board’s approval. Fiscal Analysis The engineer’s construction estimate is $2,927,300. The total project cost of $3,615,000 includes estimated construction costs, contingency, staff engineering, staff communications and construction management, and inspection services. A summary of the estimated costs and available funds is shown in the table below: June 21, 2022 Item #7 Page 3 of 11 Next Steps Upon the CMWD Board’s approval of the plans, specifications and contract documents, the Secretary of the Board of Directors will advertise a request for bids to construct the project. Staff will evaluate the bids received and the lowest responsive and responsible bidder will be identified. Staff will then return to the CMWD Board to consider the lowest responsive and responsible bid and possible award of a contract to the identified bidder, which is expected to be in fall 2022. Construction duration is 12 months. Staff anticipate completion of construction to be in fall 2023. Environmental Evaluation The project classifies as a replacement or reconstruction of existing utility and/or facilities involving negligible or no expansion of capacity and the City Planner has determined it is exempt from environmental review according to California Environmental Quality Act Guidelines Section 15302 (c). If the resolution is approved, staff will file a notice of exemption with the San Diego County Clerk in compliance with Section 21152 (b) of Public Resources Code. No exception to the exemption as set forth in Guidelines Section 15300.2 applies. Public Notification This item was noticed in accordance with the Ralph M.
