Subject: Update on Intersection Traffic Control Options for the Carlsbad Boulevard and Tamarack Avenue Intersection Improvements Project
District 1
Recommended Action
Receive an update on the City Council’s decision regarding the Carlsbad Boulevard and Tamarack
Avenue Intersection Improvements Project.
Executive Summary
The Carlsbad Boulevard and Tamarack Avenue Intersection Improvements Project (Capital
Improvement Program Project No. 6058) is intended to enhance traffic operations, pedestrian
safety, and coastal access at the intersection of Carlsbad Boulevard and Tamarack Avenue.
In July 2023, the City Council approved a conceptual design for the project, featuring a
roundabout, pedestrian safety improvements, and a widened sidewalk on the bridge over the
Agua Hedionda Lagoon inlet (Resolution No. 2023-206). Staff were directed to proceed with
design and environmental permitting efforts but to defer construction approval until traffic
performance data could be collected from the nearby Carlsbad Boulevard and Cannon Road
roundabout, after this project is constructed.
The project is partly funded by a $1.054 million Active Transportation Program grant from the
San Diego Association of Governments (SANDAG). In November 2024, the City Council authorized
a request to SANDAG to amend the grant scope to exclude construction and extend the grant
deadline by two years. However, two SANDAG committees subsequently recommended denying
the city’s request, and the SANDAG Board has postponed further discussion. The grant is
currently set to expire on May 8, 2025, unless action is taken.
This report is provided in response to a minute motion by the Traffic Safety & Mobility
Commission from its April 7, 2025, meeting:
TRAFFIC SAFETY & MOBILITY COMMISSION
May 5, 2025 Item #3 Page 1 of 18
Staff Report
Minute motion by Commissioner Kohl, seconded by Commissioner Proulx, requesting to
agendize an item for a future meeting to receive a presentation regarding the San Diego
Association of Governments (SANDAG) Active Transportation Grant Program-funded
Carlsbad Boulevard and Tamarack Avenue Pedestrian Improvement Project – 6/0/1
(Coelho – Absent).
Discussion
Given the circumstances, staff presented three options to the City Council at its meeting on April
29, 2025:
1. Option 1 – Proceed with a roundabout as previously approved.
2. Option 2 – Shift to a traffic signal design at the intersection.
3. Option 3 – Pursue a smaller scale project focused on pedestrian and ADA improvements.
Each option was analyzed based on cost, construction feasibility, consistency with transportation
policies, and potential to retain grant funding. Option 3 would be the least costly (estimated $2
million), while Options 1 and 2 would cost over $17–19 million each and face longer
implementation timelines.
A full description of the options, fiscal impacts, and project history is provided in the attached
City Council staff report (Exhibit 1).
City Council Direction
Following review of the staff report and consideration of public feedback, the City Council made
a motion to proceed with Option 3, which includes a smaller scale project with limited
improvements at the Carlsbad Boulevard and Tamarack Avenue intersection. The motion was
adopted 5/0/0. This direction was based on public comment received at the meeting and to
deliver near-term safety and accessibility enhancements while minimizing project costs and
avoiding further delays. City Council members acknowledged the funding constraints and
uncertainty surrounding the SANDAG grant extension and determined that a streamlined project
scope offered the most feasible path forward. Option 3 will allow staff to continue with
environmental review, permitting, and final engineering, while preserving the opportunity to
pursue additional improvements in the future.
A video of the agenda item presentation and discussion of Item No. 9 is provided at:
https://carlsbadca.new.swagit.com/videos/341348
Next Steps
Staff will proceed with Option 3 as directed by the City Council, including coordination with
SANDAG regarding grant funding, advancing environmental review and permitting, and
preparing final engineering designs.

Subject: Intersection Traffic Control Options for the Carlsbad Boulevard and
Tamarack Avenue Intersection Improvements Project
District: 1
Recommended Action
1.Adopt a resolution confirming the City Council-adopted Resolution No. 2023-206, approving
a roundabout as the intersection traffic control option for the Carlsbad Boulevard and
Tamarack Avenue Intersection Improvements Project (Exhibit 1); or
2.Adopt a resolution approving a traffic signal at the intersection of Carlsbad Boulevard and
Tamarack Avenue as the preferred intersection traffic control option for the Carlsbad
Boulevard and Tamarack Avenue Intersection Improvements Project (Exhibit 2); or
3.Adopt a resolution approving a smaller scale project with limited improvements for the
Carlsbad Boulevard and Tamarack Avenue Intersection Improvements Project (Exhibit 3)
Executive Summary
The city has a Capital Improvement Program project to make significant improvements to the
Carlsbad Boulevard and Tamarack Avenue intersection based on a conceptual design the City
Council approved in 2023. (See Resolution No. 2023-206 included in Exhibit 4.) That design
includes a roundabout at the intersection, pedestrian safety improvements and a wider
sidewalk on the bridge over the Agua Hedionda Lagoon inlet. The project was to be partly
funded by a $1.054 million grant from the San Diego Association of Governments (SANDAG).
On Nov. 12, 2024, the Carlsbad City Council approved a request to SANDAG to amend the scope
of the grant by removing the construction phase and extending the grant by two years, so that
it would apply to just the earlier phases of the project. The amendment was intended to
change the grant scope to remove the construction phase from the grant funding scope and
extend it for two years. This is consistent with the City Council’s direction to postpone
construction of the project until more data can be collected and evaluated on how traffic is
performing at the nearby roundabout at Carlsbad Boulevard and Cannon Road intersection, as
the City Council had previously directed.
April 29, 2025 Item #9 Page 1 of 16
Exhibit 1
May 5, 2025 Item #3 Page 3 of 18
Two SANDAG committees have since recommended against supporting the request, and the
SANDAG Board of Directors have postponed a discussion on the issue.
This delay presents an opportunity for the City Council to re-evaluate the project’s scope and
implementation approach. If no action is taken by the City Council and SANDAG, the grant will
expire on May 8, 2025.
Staff are requesting the City Council’s decision on whether to follow the City Council’s previous
direction to proceed with the design and environmental permitting of a roundabout and wait
before proceeding with construction until five months after completion of the Carlsbad
Boulevard and Cannon Road roundabout, which would likely mean the city would not receive
the approximately $455,000 remaining in the grant funds, or to take another approach.
Explanation & Analysis
Timeline
The City Council authorized the Public Works Director to apply for a grant from SANDAG under
the Active Transportation Grant Program for the Carlsbad Boulevard and Tamarack Avenue
Intersection Improvements Project (Capital Improvement Program Project No. 6058), accepting
the terms of the grant agreement, on March 10, 2015,
• The Public Works Director signed the original grant for $1,054,000 on May 9, 2016.
• SANDAG provided two extensions to the grant term to allow the city more time to
collaborate on the project details with California State Parks, which owns land
immediately adjacent to the project area.
o Amendment No. 1 to the grant was approved by SANDAG On April 17, 2019,
extending the grant termination date to May 9, 2022.
o Amendment No. 2 to the grant was approved by SANDAG On May 3, 2022,
extending the grant termination date to May 8, 2025.
• On July 18, 2023, the City Council approved the conceptual design of the project, which
includes a roundabout at the intersection, pedestrian safety improvements and
widening the sidewalk on the bridge over the Agua Hedionda Lagoon inlet. (See
Resolution No. 2023-206 included in Exhibit 4.) The City Council authorized staff to
proceed with the project’s next steps, which include its final design and environmental
permitting, and directed staff to return with information on five months of traffic
performance at the coastal roundabout project at the intersection of Carlsbad
Boulevard and Cannon Road before seeking the City Council’s approval for construction.
That roundabout is expected to be completed in 2028. The staff report is provided in
Exhibit 4.
• On Nov. 12, 2024, the City Council authorized staff to ask SANDAG to amend the scope
of work to remove the construction phase and request a 24-month time extension of
the grant for the project. (Resolution No. 2024-245.)
• On Feb. 12, 2025, SANDAG’s TransNet Independent Taxpayer Oversight Committee
recommended that the SANDAG Board reject the city’s request. Committee members
expressed concern that the city’s request was unrealistic due to too many uncertainties,
such as the lack of a California Coastal Commission permit and environmental clearance
for the project, and stated it was unlikely that the project could be completed in the
timeframe the city has requested.
April 29, 2025 Item #9 Page 2 of 16May 5, 2025 Item #3 Page 4 of 18
• On March 21, 2025, the SANDAG Transportation Committee also recommended that the
SANDAG Board reject the city’s request. Some Transportation Committee members
expressed support for the project and noted it has region-wide benefits but also had
concerns about the progress to date, the absence of funding to construct the project
and the City Council’s decision to wait to approve the final design until another
roundabout project is completed and studied, which they said leaves the project’s
design and construction timeline uncertain.
• SANDAG’s Board of Directors were scheduled to discuss the grant at its March 28, 2025,
meeting, but the item was removed from the meeting’s agenda, to be scheduled at a
later date.
Grant terms
The grant was initially approved in the amount of $1,054,000, requiring a 42% local match by
the city to result in a total cost of $1,804,000.
The city has so far invoiced SANDAG for reimbursement of $599,186, which includes two
pending invoices totaling $10,896. The city has received $531,415 in cash payments because
SANDAG retains 10% of each payment to the city. Those retained funds are to be released to
the city after the project is completed.
The remaining balance of the grant is approximately $455,000.
Options
Staff offer the following options for the City Council’s consideration:
1. Adopt a resolution confirming the City Council’s previous direction in Resolution No. 2023-
206 approving a roundabout as the intersection traffic control option at the Carlsbad
Boulevard and Tamarack Avenue intersection for the Carlsbad Boulevard and Tamarack
Avenue Intersection Improvements Project. (Exhibit 1. Additional information on this option
and a copy of Resolution No. 2023-206 can be found in the July 18, 2023, staff report
provided as Exhibit 4.)
Pros
• Roundabouts can reduce vehicle conflict points with other vehicles, pedestrians
and bicycles as well as reduce vehicular speeds
• The roundabout option will result in the shortest delay for drivers, which means
traffic will move more efficiently through the roundabout compared to the
intersection with a traffic signal
• Roundabouts force cars to slow down and slower speeds tend to reduce the
severity of injury collisions
• Roundabouts are self-enforcing, meaning the design causes drivers to use more
caution
• Roundabouts result in less air pollution and electricity usage
• Roundabouts decrease acceleration noise from motorcycles and other loud
vehicles along the coast
• Meets the City Council’s policies related to traffic safety, mobility and
environmental sustainability
• The Traffic Safety & Mobility Commission recommended the roundabout option
on May 1, 2023
April 29, 2025 Item #9 Page 3 of 16May 5, 2025 Item #3 Page 5 of 18
• The San Diego County Bicycle Coalition supports the roundabout option as the
best design for cyclists of all types
Cons
• No construction funding has been identified for this option, which is estimated
to cost over $19 million
• Roundabouts are relatively new to Carlsbad, and some community members
have expressed concerns regarding a roundabout at this location due to the
large number of visitors and residents who use the intersection
• Construction may not start until 2029 because, in keeping with the City Council’s
direction, the final approval of this option is contingent upon review for five
months and satisfactory performance of the roundabout at the intersection of
Carlsbad Boulevard and Cannon Road, which is targeted to be completed in 2028
• The SANDAG Board could decide not to support the city’s request for the grant
extension for the reasons cited by the two SANDAG committees, which include
the City Council’s decision to wait to approve the final design until another
roundabout is completed and studied, thereby leaving the project’s design and
construction timeline uncertain
2. Adopt a resolution approving a traffic signal at the intersection of Carlsbad Boulevard and
Tamarack Avenue as the preferred intersection traffic control option for the Carlsbad
Boulevard and Tamarack Avenue Intersection Improvements Project. (Exhibit 2. Additional
information can be found in the July 18, 2023, staff report provided as Exhibit 4.)
Pros
• Also meets the City Council’s policies related to traffic safety, mobility and
environmental sustainability
• Enhances safety compared to the existing conditions
• Projections show the traffic signal would satisfactorily accommodate future
traffic flow until 2035
• Drivers are more accustomed to traffic signals
Cons
• No construction funding has been identified for this option, which is estimated
to cost over $17 million
3. Adopt a resolution approving a smaller scale project with limited intersection improvements
for the Carlsbad Boulevard and Tamarack Avenue Intersection Improvements Project.
(Exhibit 3.)
Pros
• The project design would be simpler and could be designed, permitted and
constructed faster
• The improvements would include an enhanced pedestrian pathway and
crosswalks and upgraded curb ramps to meet the current Americans with
Disabilities Act, or ADA, standards
• The estimated cost of $2 million is significantly lower than the first two options,
which would depend on the grade changes associated with creating pedestrian
pathways conforming to the current ADA standards
April 29, 2025 Item #9 Page 4 of 16May 5, 2025 Item #3 Page 6 of 18
• This option may help secure the remaining SANDAG grant and future grant funds
by providing a streamlined target delivery schedule that is not contingent upon
other projects and providing additional support documenting that the city is
committed to completing improvements at the intersection within a shorter time
frame
Cons
Not all the construction funding has been identified for this option
• Provides limited enhancements compared with Options 1 and 2
Fiscal Analysis
All three options would require additional appropriations at a future date. Option 3 is the least
expensive option, with a current cost estimate of $2 million as compared to over $19 million for
Option 1 and over $17 million for Option 2.
Amending the scope of the grant for Option 3 may allow the city to maximize the use of the
remaining grant funding, which is approximately $455,000. SANDAG would still need to approve
the requested 24-month time extension and the change in the project’s scope, but the
construction phase would still be included.
Next Steps
Upon the City Council’s direction, staff will work with SANDAG staff and submit a revised
request to amend the grant agreement, depending on which option is selected. Staff will also
work on the environmental review and permitting and final engineering design consistent with
the City Council-approved design option.
If the City Council takes no action and the SANDAG Board does not approve the amendment to
the grant agreement so that the requested time extension and scope change are not approved
prior to the grant expiring on May 8, 2025, staff would proceed with the City Council’s prior
direction in Resolution No. 2023-206 of continuing with design and environmental permitting of
the roundabout option and would request additional funding for design and environmental
permitting of approximately $455,000 at a future date, if needed.
Staff would also return to the City Council with its evaluation of the performance results of the
Carlsbad Boulevard and Cannon Road roundabout five months after its construction completion
and request a budget appropriation for construction of the Carlsbad Boulevard and Tamarack
Avenue Intersection Improvements Project roundabout option once the designs are completed.
Carlsbad Boulevard and Tamarack Avenue Intersection Improvements Project
Capital Improvement Program Project No. 6058
Total appropriation to date $2,908,569
Total expenditures and encumbrances to date -$1,861,117

Remaining balance (estimated, if grant extension is not approved) $592,452
April 29, 2025 Item #9 Page 5 of 16May 5, 2025 Item #3 Page 7 of 18
Environmental Evaluation
The proposed action to either confirm the roundabout option or approve a new preferred
intersection control option is statutorily exempt from environmental review under California
Environmental Quality Act Guidelines Section 15262 as it involves only feasibility or planning
studies, including consideration of environmental factors, for possible future actions that have
not been approved, adopted or funded. The proposed action does not have a legally binding
effect on any possible future discretionary action.

which includes a smaller scale project with limited improvements at the intersection of Carlsbad
Boulevard and Tamarack Avenue as the preferred option, and authorized staff to move forward with
the environmental review, permitting and final engineering design of the Project; and
WHEREAS, no additional funding is needed at this time but staff will return with a request for
additional design funding if the SANDAG grant is not extended and at a future date for funding of the
construction phase.
NOW, THEREFORE, BE IT RESOLVED by the City Council of the City of Carlsbad, California, as
follows:
1. That the above recitations are true and correct.
2. That the proposed action to approve a preferred intersection design option is statutorily
exempt from environmental review under CEQA Guidelines Section 15262 as it involves
only feasibility or planning studies, including consideration of environmental factors, for
possible future actions that have not been approved, adopted or funded. The proposed
action does not have a legally binding effect on any possible future discretionary action.
3. That the City Council approves a smaller scale project with limited improvements at the
Carlsbad Boulevard and Tamarack Avenue intersection as the preferred intersection
design option.
4. That staff are authorized to move forward with environmental review, permitting, and
final engineering for the selected design option of a smaller scale project with limited
intersection improvements for the Carlsbad Boulevard and Tamarack Avenue
Intersection Improvements Project, CIP Project No. 6058.

Subject:Public comment on 5/5/2025 Item #3 (Carlsbad Blvd/Tamarack Ave intersection control)
Date:Friday, May 2, 2025 2:29:49 PM
Traffic Commissioners:
I encourage you to read all of the correspondence received (Item #9) for the 4/29/2025 City
Council meeting on this item, as well as watch the meeting itself. There are numerous verythoughtful comments.
While on your commission, I supported multiple roundabouts and traffic circles. However, the
proposed one at Tamarack Avenue is very problematic. In addition, the North Countyroundabouts in the same class have had terrible collision and injury histories, including the
one at State Street in Carlsbad and El Portal Street in Encinitas--each with the highest collisionrates in their respective cities, including numerous pedestrian and bicycle involved collisions
and numerous severe injuries. I covered this in my presentation at the City Council meeting inthe link above.
Best regards,
Steve Linke
