Re: Carlsbad Boulevard Water and Sewer Improvements at Terramar Project Update (District 2)
This memorandum provides an update to a previous Council Memorandum dated December 12, 2024, on the Carlsbad Boulevard Water and Sewer Improvements at Terramar Project (Project), Capital Improvement Program {CIP) Project Nos. 5048 and 5503-20 (Attachment A).
Background
On May 14, 2024, the CMWD Board of Directors and the City Council adopted resolutions to award a contract to SEMA Construction, Inc., in the amount of $4,783,628 for the Project.
The Project replaces some of the oldest asbestos concrete water mains in the city, approximately 5,000 linear feet (LF), and will abandon and/or remove 7,600 LF of water mains.
It will also replace and/or rehabilitate 1,500 LF of sewer mains and access holes. 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-quarter mile segment on Cannon Road from Carlsbad Boulevard east across the railroad tracks to Avenida Encinas.
Discussion
The Notice to Proceed was issued on August 30, 2024, and the underground work to replace the sewer and water pipelines is ongoing. The Project experienced delays due to San Diego Gas & Electric's {SDGE) slurry encasement of water utilities that was discovered after the start of construction and needed to be addressed before the Project could continue. SDGE completed this additional work at the end of January 2025.
The original project schedule included summer work restrictions due to the California Coastal Commission's Coastal Development Permit. City staff worked with Coastal Commission staff to revise the summer restrictions to avoid further construction delays and costs to the Project. A new Coastal Development Permit Waiver was approved by the Coastal Commission on March 13, 2025, which allows work to be performed during the summer months, Mondays through Fridays.

Public Works staff are working with Communication & Engagement Department staff to continue advanced notification and coordination with the residents and businesses that will be temporarily impacted during these facility improvements.
Next Steps
Construction will continue during the summer months in 2025, and the estimated construction completion date for the project is early 2026.

Utility Improvements in the Downtow'rrand Terra mar Area Update (Districts 1 & 2) This memorandum provides an update to a previous Council Memorandum dated October 13, 2022, provided as Attachment A, on two water and sewer utility replacement projects: the Carlsbad Boulevard Water and Sewer Improvements at Terramar, Capital Improvement Program {CIP) Project Nos. 5048 and 5503 (District 2), and the Downtown and Terramar Water Main Replacement, CIP Project No. 3904-C (Districts 1 and 2).
Background
Attachment A provides background information on the projects, including descriptions of the improvements.
Discussion
Carlsbad Boulevard Water and Sewer Improvements, CIP Project Nos. 5048 and 5503 The project will replace or rehabilitate approximately 5,100 lineal feet (LF) of water and sewer utilities along Carlsbad Boulevard and Cannon Road and is in the final design phase, which is estimated for completion in December 2023. The California Coastal Commission will consider granting a Coastal Development Permit {CDP) Waiver in October 2023, completing the discretionary permit process and allowing the project to advance to the bidding phase.
On September 20, 2023, the Planning Commission adopted a resolution to approve CDP 2022-0056, for the water and sewer utility improvements. Also, the Planning Commission adopted a resolution to approve a third addendum to the final Addendum to the Program Environmental Impact Report (PEIR) for the Water, Recycled Water and Sewer Master Plan Updates, which determined that these utility projects are consistent with California Environmental Quality Act (CEQA) Guidelines Sections 15162-15164.
Staff will continue to coordinate with the Coastal Commission, which reserves permitting authority in and north of Cannon Road, to obtain a CDP Waiver for the project. The Coastal Commission mailed notices to residents within a 100-feet radius of the project site to notify them that approval of a CDP Waiver will be noticed as part of the Deputy Director report for the San Diego Coast District at the Coastal Commission's meeting on October 12, 2023. The project is subject to the Coastal Commission's summer work moratorium and any required construction scheduling constraints will be specified in the contract documents.

• Hemlock Avenue -535 LF of pipe and 15 services (September-October 2023) • Shore Drive -1,200 LF of pipe and 33 services (October-November 2023) Each pipeline segment location required some design changes due to existing utility conflicts.
Change orders to date total $180,125, with a remaining contingency balance of $191,125.
To date, there are no archaeological or cultural resource findings, though monitoring will continue through the end of excavation activities.

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 pQrtion 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 offleld 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 Terra mar 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. Ail 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 8l 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.
