Background
Outreach and construction act ivities on these two construction projects have begun and will continue until the end of 2024, as further described below. Phased construction is planned to minimize disruption of water service to the residents and businesses served. Public Works staff are working with the Communication & Engagement Department to reach out in advance of these critical projects to meet with, notify and coordinate with the businesses and residents that will be temporarily impacted during these facility improvements.
Carlsbad Boulevard Water and Sewer Improvements at Terramar, CIP Project Nos. 5048 and 5503 (District 2)
A Council Memorandum dated April 7, 2022, provides background information on CIP Project Nos. 5048 and 5503. This project will replace some of the oldest asbestos cement (AC) water mains in the city, approximately 5,000 lineal feet, and will abandon and/or remove 7,600 lineal feet of water mains. It will also replace and/or rehabilitate 1,500 lineal feet of sewer mains and manholes. The project is located on Carlsbad Boulevard from Tierra Del Oro Street south to approximately 300 feet south of Manzano Drive. It also includes a one-quar ter mile segment on Cannon Road from Carlsbad Boulevard east across the railroad tracks to Avenida Encinas.
Downtown and Terramar Water Main Replacement, CIP Project No. 3904-C (Districts 1 & 2) On August 30, 2022, Carlsbad Municipal Water District {CMWD) awarded a contract to Burtech Pipeline Incorporated for construction of CIP Project No. 3904-C. This project will replace approximately 4,400 lineal feet of aging AC water mains with eight-inch diameter polyvinyl chloride (PVC) wate r mains that serve five residential areas and one business area at the following locations:
• State St reet alley - from Grand Avenue to Carlsbad Village Drive • Juniper Avenue - from Carlsbad Boulevard to Garfield Street • Hemlock Avenue - from Carlsbad Boulevard to Garfield Street Public Works Branch

Carlsbad Boulevard Water and Sewer Improvements at Terramar, CIP Project Nos. 5048 and 5503 (District 2)
The project preliminary design is complete and final design is in progress.
On August 29, 2022, staff presented the proposed utility work to the California Coastal Commission, which reserves permitting authority north of Cannon Road. Coastal Commission staff opined that the portion of the project within the Local Coastal Plan area of deferred certification should qualify for a Coastal Development Permit (CDP) waiver. Staff will continue to work with the Coastal Commission for approval of the CDP waiver. The Planning Division of the Community Development Department will also review the project for conformance with the city's Local Coastal Plan, and staff are preparing the applications to initiate that process.
Subsurface investigations for the project will continue in October 2022 along Carlsbad Boulevard and Cannon Road. Utility potholing will commence at 20 locations in one to two weeks throughout the project area. This is a continuation of field exploration which began in late June when three soil borings were completed at these locations. These investigations will allow the project design to be finalized in the coming months. Public Works staff are working with the Communication & Engagement Department on notifications related to these activities.
Water and sewer utilities construction is estimated to commence in fall 2023 and be completed in late 2024. The project is subject to the Coastal Commission's summer work moratorium, and the construction scheduling constraints to be specified in the contract documents will be developed in consideration of CIP Project No. 3904-C construction activities.
Downtown and Terramar Water Main Replacement, CIP Project No. 3904-C (Districts 1 & 2) Construction of the Downtown and Terra mar project will commence in the coming months. Construction activity is anticipated to start at Tierra del Oro Street and Shore Drive, followed by the State Street alley site, then at three other sites on Garfield Street, Hemlock Avenue and Juniper Avenue.
Construction will occur over an estimated 14-month period with minimal work during summer months. All the sites have scheduling challenges related to the summer construction moratorium on Carlsbad Boulevard, the Farmer's Market at State Street, or water demand requirements of the Hubbs Research Center, which leaves limited options for construction scheduling. The construction periods for each site will be determined within the next several weeks with the approval of the contractor's construction schedule.
Phased construction is planned to minimize disruption of water service to the residents and businesses served. Public Works staff are working with the Communication & Engagement Council Memo - Utility Improvements in the Downtown and Terramar Area Update (Dist. 1 & 2) October 13, 2022
Department to reach out in advance of this critical project to meet with, notify and coordinate with the businesses and residents that will be temporarily impacted during these facility improvements.
