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 t he 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 adopt ed 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
Environment al Impact Report (PEIR) for the Water, Recycled Water and Sewer Master Plan
Updates, which determined that these utility projects are consistent with California
Environmental Qualit y Act (CEQA) Guidelines Sect ions 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 t he 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.

Downtown and Terramar Water Main Replacement, CIP Project No. 3904-C
The Carlsbad Municipal Water District (CMWD) Board awarded a contract in the amount of
$2,475,000 on August 30, 2022, and construction of the project is approximately 61%
completed. The following phases of pipeline installation are completed:
• Tierra del Oro -785 LF of pipe serving 20 customers installed February-May 2023
• Juniper Avenue -540 LF of pipe serving 22 customers installed April-May 2023
• State Street Alley-440 LF of pipe serving 11 businesses installed May-June 2023
• Garfield Street -900 LF of pipe serving 37 customers installed June-August 2023
The remaining locations are currently in construction and expected to be completed as follows:
• 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.
Next Steps
Carlsbad Boulevard Water and Sewer Improvements, CIP Project Nos. 5048 and 5503
Upon completion of final design and receipt of the CDP Waiver, staff will seek authorization
from the CMWD Board to advertise the project for bids and will return in early 2024 for
acceptance of bids and contract award. If approved, water and sewer utilities construction is
estimated to commence in Spring 2024 and be completed in Summer 2025. Staff will continue
to work with Community & Engagement staff to inform Terra mar area residents of the project's
status.
Street improvements proposed for the Terra mar Area Coastal Improvements, CIP Project No.
6054, will follow completion of the water and sewer utility improvements.
Downtown and Terramar Water Main Replacement, CIP Project No. 3904-C
Staff will continue to work with businesses and residents temporarily impacted during the
remaining pipeline improvements. CMWD Operations staff will continue to need to shut down
the water systems as part of the connection process to the new pipeline and connection to the
water distribution system.
Final trench repaving at all sites is scheduled for December 2023 and January 2024, and the
final project close-out is expected in early 2024.

Utility Improvements in the Downto~nd Terramar Area Update (Districts 1 & 2)
This memorandum provides an update on two water and sewer utility replacement projects:
the Carlsbad Boulevard Water and Sewer Improvements at Terra mar, 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 & 2).
Background
Outreach and construction activities 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
t hat 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-quarter 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) water mains that serve five residential areas and one business area at the
following locations:
• State Street alley-from Grand Avenue to Carlsbad Village Drive
• Juniper Avenue -from Carlsbad Boulevard to Garfield Street
• Hemlock Avenue -from Carlsbad Boulevard to Garfield Street

Discussion
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 investigat ions 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 Terramar 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 sit e 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 Terra mar 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.
Next Steps

areas is as follows:
o October 2022 -Subsurface utility investigations/potholing work will occur in Carlsbad
Boulevard and Cannon Road, as part of Carlsbad Boulevard Water and Sewer
Improvements at Terramar, CIP Project Nos. 5048 and 5503
