Subject: Carlsbad Boulevard and Tamarack Avenue Intersection Improvements,
Capital Improvement Program Project No. 6058
Recommended Action
1. Receive a presentation regarding the Intersection Control Alternatives Analysis for the
Carlsbad Boulevard and Tamarack Avenue Intersection Improvements Project, Capital
Improvement Program Project No. 6058; and
2. Receive input from the community; and
3. Support staff’s recommendation to the City Council to implement a modern-day
roundabout at the intersection of Carlsbad Boulevard and Tamarack Avenue.
Executive Summary
The City of Carlsbad is committed to creating “complete streets,” roads that are safe and
accessible, while balancing the needs of drivers, bicyclists, walkers, and other road users. One
area the city is redesigning into “complete streets” is Carlsbad Boulevard and Tamarack
Avenue, which will address the narrow sidewalk over the bridge, the bus stop in the center
median island, efficient intersection control, and making more room for walkers and bikers.
In 2015, the city received a grant from the San Diego Association of Governments Active
Transportation Grant Program, or ATGP. The Carlsbad Boulevard and Tamarack Avenue
Intersection Improvements project was selected for the grant because it promotes active
transportation improvements and traffic calming at this heavily traveled segment of Carlsbad
Boulevard to make it safe for all users. Additionally, the improvements meet the guiding
principles set forth by the city’s General Plan Mobility Element, which the City Council adopted
in 2015. While this project started before the city’s current traffic safety emergency, the
proposed improvements support the city’s focus on creating safer streets for all modes of
transportation.
The project also serves to close a critical multimodal gap in the transportation network by
improving the bicycle, pedestrian and transit environment on Carlsbad Boulevard. Operational
Feb. 6, 2023 Item #4 Page 1 of 324
enhancements to all modes provided by the project will improve connectivity and safety for all
users.
Staff have completed a variety of analyses and have worked with project neighbors and the
community to get their input on potential designs for the area. Two options for reconfiguring
the intersection of Carlsbad Boulevard and Tamarack Avenue are feasible.
Both options will widen the walking path over the bridge just south of Tamarack Avenue,
relocate the bus stop and add street parking. The options differ in how they manage traffic
flowing through the intersection. One features a traffic signal and the other a roundabout. The
city’s first roundabout on Carlsbad Boulevard is north of the project site at State Street, and the
City Council has approved another roundabout at Cannon Road and Carlsbad Boulevard.
Based on staff’s intersection control alternatives analysis focused on vehicle, bicycle, and
pedestrian modes, improved safety and best meeting the city’s policies for mobility, staff
recommend option two, roundabout.
Discussion
The Carlsbad Boulevard and Tamarack Avenue Intersection Improvements, Capital
Improvement Program, or CIP, Project No. 6058 incorporates elements from the Mobility
Element of the General Plan and Sustainable Mobility Plan. The project limits are provided in
Exhibit 1 Location Map.
With the goal to enhance safety for all users including drivers, walkers and bicyclists, the scope
of work proposes improvements such as:
• Reconfiguration of the intersection to provide efficient traffic flow
• Widening of the sidewalk, including to the south across the bridge
• Relocating the North County Transit District bus stops to provide safer access
• Improving pedestrian and bike facilities
• Improving Americans with Disabilities Act, or ADA, facilities
Background
The City of Carlsbad has received approval from the San Diego Association of Governments, or
SANDAG, two 36-month grant extensions. The second extension of the ATGP will expire in May
2025. The city considers this project as a high-profile project since it is along the coast and
would impact many city residents and visitors. In addition to temporary construction impacts,
the project will also have a permanent impact on the look and the feel of the whole area. Due
to these impacts, the city conducted an extensive public outreach effort to gather the public’s
input.
As part of the public engagement process from 2016 to 2018, staff hosted two community
workshops and open houses, an online survey, an in-person survey, and four on-site public
informational questions and answers. Staff additionally presented the project’s proposed
improvements to the California Coastal Commission and made presentations to the former
Traffic Safety Commission, now known as the Traffic & Mobility Commission. Staff incorporated
Feb. 6, 2023 Item #4 Page 2 of 324
feedback from these engagements to develop and refine design options for the intersection
improvements and associated technical studies.
During the preliminary assessment, topographic and site surveys revealed property line
ambiguities between the city and the California Department of Parks and Recreation, or State
Parks, properties. Staff have been in ongoing coordination with State Parks staff since early
2018 to address the long-term operating and maintenance associated with the project.
City staff have also worked with State Parks staff to receive concurrence on conceptual
intersection control designs since portions of the project are located within the State Park’s
right-of-way. Three alternatives were presented to State Parks for consideration, and additional
evaluation was prepared to address their comments. In 2021, city staff received a concurrence
letter from State Parks staff on the project’s conceptual designs.
Once city staff received the concurrence letter on the conceptual design options from State
Parks, staff advertised a request for qualifications in summer 2021 for engineering and
environmental services for the project. The city’s selection panel completed negotiations with
the selected firm, Wood Rodger, Inc. In March 2022, the City Council approved a professional
services agreement with Wood Rodgers, Inc. to provide engineering and environmental services
for the project.
Existing Conditions
Carlsbad Boulevard and Tamarack Avenue is currently a signalized intersection with pedestrian
crosswalks on the north and east legs. The northbound and southbound approaches currently
include protected left-turn phasing and the eastbound and westbound approaches include split
phasing. The study area consists of the following roadway segments that make up the four
approaches of the study intersection:
Carlsbad Boulevard:
•A four-lane roadway that runs north-south between the city limits.
•The southbound approach of the study intersection includes two through lanes, a
southbound left-turn pocket, and a signal-controlled channelized southbound right-turn
lane.
•The northbound approach includes one through lane, a shared through-right turn lane,
and a northbound left-turn pocket.
•Based on the General Plan Mobility Element (Mobility Element), Carlsbad Boulevard is
designated as an Identity Street north of Tamarack Avenue and as a Coastal Street south
of Tamarack Avenue.
Tamarack Avenue:
•A two-lane roadway with a two-way left-turn lane that generally runs east-west
between Carlsbad Boulevard and College Boulevard.
•Tamarack Avenue forms the westbound approach of the study intersection and contains
one shared through-right turn lane and a left-turn pocket.
•Tamarack Avenue is designated as a Neighborhood Connector Street.
Feb. 6, 2023 Item #4 Page 3 of 324
Beach Access Road
• A local access road that provides access to Tamarack State Beach parking lot.
• The Beach Access Road forms the eastbound approach to the study intersection and
contains a shared through-left turn lane, and a stop-controlled channelized right-turn
lane.
Existing Pedestrian Facilities
Within the project area, sidewalks exist along both sides of Carlsbad Boulevard and Tamarack
Avenue. Sidewalk along the west side of Carlsbad Boulevard south of Tamarack Avenue is 4-
feet-wide and buffered by a guardrail. Sidewalk along the west side of Carlsbad Boulevard north
of Tamarack Avenue is 8-feet-wide buffered by a landscaped area. Only two crosswalks exist at
the project intersection with push buttons, countdown signal heads, curb ramps on the north
and east legs of the intersection. Also, in the nearby vicinity is the Agua Hedionda trail head and
Coastal Rail Trail facilities.
Additionally, the existing conditions include narrow sidewalks, especially along the bridge
where people commonly walk in the bike lane. Currently there are no ADA compliant crossings
at this intersection.
Existing Bicycle Facilities
The project area includes Class II bike lanes. A Class II bike lane provides a delineated pathway
assigned to bicyclists to enable more predictable movements, accommodating bicyclists
through corridors. These Class II bike lanes are located along the northbound and southbound
Carlsbad Boulevard, and along the eastbound and westbound Tamarack Avenue.
Existing Transit Facilities
Immediate in the project area are North County Transit District, or NCTD, bus stops. The bus
stops are located on northbound Carlsbad Boulevard, approximately 170 feet north of
Tamarack Avenue, and on southbound Carlsbad Boulevard within the refuge island on the west
leg of the intersection. Both stops contain signage; however, there are currently no ADA-
compliant pedestrian facilities providing access to the stop on southbound Carlsbad Boulevard.
Guiding Principles
The goal of the Carlsbad Boulevard and Tamarack Avenue Intersection Improvement Project is
to accommodate all modes of transportation and improve beach access while promoting active
transportation and traffic calming at this heavily traveled segment of Carlsbad Boulevard. This
will make it safer for all modes of users and ensure an exceptional coastline experience in all
the ways people want to enjoy it.
The project improvements are proposed in accordance with the local policies, including
complete streets, Mobility Element of the General Plan, Sustainable Mobility Plan and Climate
Action Plan. The intent of complete streets is to create roads where all modes of transportation
are considered, to get people safely where they want to go by their choice of travel, walking,
biking, or driving. This policy reflects a new way of thinking about how people get around
Carlsbad, moving from managing car traffic to an approach focused on all modes of travel.
Feb. 6, 2023 Item #4 Page 4 of 324
The city’s Sustainable Mobility Plan includes specific guidance on the consideration of
roundabouts for intersection control which states, “The City of Carlsbad recognizes that
roundabouts are an effective intersection traffic control measure to calm traffic and improve
safety of intersections for pedestrians, bicyclists, and vehicles by reducing speeds and conflict
points. Roundabouts have added benefits of improving efficiency of vehicle operations of
intersections, reducing greenhouse gas emissions from idling vehicles and enhancing aesthetics.
Roundabouts will be considered on existing city streets where they could effectively address
safety or traffic operations issues or in new development projects when intersection control is
being considered. It is recognized that roundabouts may not be appropriate in the built
environment or at some high-volume intersections and shall be reviewed on a case-by-case
basis.”
In addition, the city recently declared state of local emergency for bike, e-bike and traffic safety
following an over 200% increase in bike and e-bike collisions since 2019. Since the traffic
emergency was declared in August 2022, and subsequently extended as of Jan. 24, 2023, the
city has made improvements to over 90 miles of local streets, increased traffic enforcement and
reprioritized traffic safety related projects. Safety is at the forefront of this project to safely
move all modes of travel through and around this intersection, while managing vehicle speeds
to promote safe pedestrian and bicycle movements.
Public input
Since the project began community feedback has helped shape the design and focus of these
improvements. Extensive outreach was conducted from 2016 to 2018, gathering the
community’s priorities and input on the potential designs. Stakeholder outreach with California
Coastal Commission and State Parks has been ongoing and will continue throughout the
engineering design and environmental permitting process.
Recently, visual simulations of the intersection control options were developed and shared with
the public to request input before moving on to the next stage. Outreach included:
• Mailer to property owners and residents located within the project area
• Community input banner hung on-site to promote the public input opportunity
• E-newsletters
• Social media posts
• Media articles
• In-person meetings with various community members and interest groups within the
project area.
Design Options
Based on previous work initiated during the early stages of the project to identify the
intersection control options, city staff and the consultant team worked to further evaluate
these options related to feasibility, operational functionality, and constructability. Two
intersection control design options are presented herein and include:
• Option 1 – Traffic Signal
• Option 2 – Single-lane Modern Roundabout
Both design options will include the following improvements:
Feb. 6, 2023 Item #4 Page 5 of 324
• Widen the sidewalk over the bridge on the west side, south of the intersection
• Relocate bus stops
• Add street parking
• Add pedestrian crossing south of Sequoia Ave, near Agua Hedionda Lagoon by the
Carlsbad Blvd Trailhead
Analysis Completed
The evaluation of these two design options for the intersection control at Carlsbad Blvd and
Tamarack Ave included a detailed analysis focused on vehicle, bicycle, and pedestrian modes.
Intersection counts were collected on May 12, 2022, when school was in session, as well as for
two summer Saturdays, June 18, 2022, and June 25, 2022. The two summer Saturday counts
were taken to satisfy the city’s Local Coastal Program requirement.
Traffic impacts and performance were evaluated based on three project scenarios using the
traffic counts collected as described above.
1. The existing conditions, which serves as the baseline.
2. The cumulative conditions that represent existing traffic volumes plus traffic projected
to be generated from near-term approved future projects that are expected to influence
the project area.
3. And lastly, the Horizon Year 2035 conditions, which is the future year scenario based on
growth found in the Transportation Forecast Information Center, or TFIC, as part of the
SANDAG’s Regional Transportation Demand Model, or RTDM.
The following was analyzed for each design option.
• Vehicular Level of Service and Delay
• Roundabout Feasibility and Operations
• Vehicular Queueing Analysis
• Pedestrian Level of Service
• Bicycle Level of Service
• Project Area Collision Summary and Safety Evaluation
The results are provided in Exhibit 2, Carlsbad Boulevard and Tamarack Avenue Intersection
Improvement Project Alternatives Analysis dated January 2023.
Option 1 – Traffic Signal
This intersection control option represents a three-lane signalized condition in which the
following improvements would be made, as shown on the cross section in Figure 1:
• Addition of high visibility pedestrian crossings on all four legs of the intersection
• Addition of green bike lane conflict zone striping that highlights the presence of
bicyclists
• Bulb-outs/curb extensions with directional curb ramps at the southeast corner of
Carlsbad Boulevard and Tamarack Avenue intersection and east leg of the Carlsbad
Boulevard and Sequoia Avenue intersection
• A parking lane and buffered bike lane on the west side of Carlsbad Boulevard north of
Tamarack Avenue
• Removal of the southbound channelized right-turn lane and conversion of one
southbound through lane to a shared-through right lane
Feb. 6, 2023 Item #4 Page 6 of 324
• Reduction of southbound Carlsbad Boulevard to one lane just before the proposed
midblock crossing
• Minimum expansion of the sidewalk width over the bridge that will vary between 8 and
15 feet
• Minimum expansion of the bike lane (varies from 6 to 8 feet) and buffer width (0 to 3
feet)

Figure 2 –Traffic Signal Simulations, looking south and north, respectively
Under the traffic signal intersection option, the intersection of Carlsbad Boulevard and
Redwood Avenue would remain full-access, however, the intersection of Carlsbad Boulevard
and Sequoia Avenue would be converted to right-in/right-out only.
Option 2 – Single-lane modern Roundabout
The roundabout intersection control option proposes many improvements similar to the traffic
signal option but with additional buffered bike lanes, and wider sidewalks. The cross section for
this option is shown in Figure 3. In the southbound direction, a lane would be dropped starting
just south of Cherry Avenue and would open back to two through lanes south of the Agua
Hedionda Lagoon bridge. In the northbound direction, a lane would be dropped south of the
Agua Hedionda Lagoon bridge and would open back to two through lanes north of Hemlock
Avenue.
Figure 3 - Roundabout Option Cross-Section Looking South on Carlsbad Boulevard
This alternative proposes the following additional differentiators from Option 1.
• An additional high visibility crosswalk on the east leg of Redwood Avenue
• ADA directional curb ramps at all pedestrian crossings within the roundabout
• Maximized with for bike lane (varies between 7 to 8 feet) with a 3-ft buffer throughout.
• Additional landscaping in and around the roundabout perimeter.

Visual simulations are included in Figure 4 to provide a graphical representation of how the
intersection may look with the single-lane modern roundabout option.
*Graphical representation only. Final design may vary.
Figure 4 – Roundabout Simulations, looking south and north, respectively
This roundabout option assumes installation of a metering signal on the eastbound approach
(west leg) with queue detection on the northbound approach (south leg) located approximately
500 feet south of the yield line. This means the vehicles approaching the roundabout from the
Beach Access Road (parking lot) will be metered in a similar fashion to a freeway on-ramp to
ensure the queue on Carlsbad Boulevard is clearing the intersection. An additional benefit of
this option is that the intersections of Carlsbad Boulevard with Redwood Avenue and Sequoia
Avenue remains fully accessible with no added restrictions.
Overall Intersection Control Options Comparison
The Alternatives Analysis process was used to evaluate and compare the two intersection
control options. In addition to city policies, engineering standards, the following criteria was
Feb. 6, 2023 Item #4 Page 9 of 324
included in the evaluation. An overall comparison between the two intersection options is
summarized in Table 1.
The evaluation criteria include:
• Pedestrian, bicycle and transit enhancements
• Traffic impacts and performance
• Environmental, including, biological resources, cultural resources and air
quality/greenhouse gas emissions
• Safety, including, collisions and conflict points and speed management
• Beach access
• Aesthetics
Although both options provide enhancements to the pedestrian, bicycle, and transit facilities
compared to current condition, the differences between the alternatives should be noted. The
roundabout provides significant benefits over the traffic signal option, including shorter
crossing distances, slower traffic speed through the intersection, less vehicle congestion,
shorter vehicle queuing distances, and lower number of potential conflict points.
For sidewalk facilities, the roundabout doubles the sidewalk width to 10 feet on the east side of
Carlsbad Blvd to the north of Tamarack Avenue, whereas with the traffic signal option it would
remain unchanged at 5 feet. On the west side of Carlsbad Boulevard, south of the intersection,
the roundabout provides maximized sidewalk width widening compared to the traffic signal
option.
Additionally, the sidewalk width over the Agua Hedionda Lagoon bridge can be maximized with
the roundabout option to provide more space for coastline access. Widening the sidewalk will
in turn enhance the coastline experience and beach activities as pedestrians and bicyclists will
feel more comfortable, reclaiming the area.
Bicycle facilities benefit the most with the roundabout option. This option provides the widest
bike lane and buffer widths (the preferred 8-foot width with 3-foot buffer). As for safety, the
roundabout option produces less than half the number of conflict points between all modes of
transportation, including vehicles, bicyclists, and pedestrians. The traffic signal option will
introduce some new conflicts points at the bus pull-outs, which will make this option have
slightly higher conflict count than the today’s current condition. The total conflict points
between vehicles and bicyclists at the intersection is only 27 for the roundabout, whereas a
high of 69 conflict points with the traffic signal option.
Traffic performance was quantified through the determination of “Level of Service”, or LOS.
Level of Service measures traffic operating conditions, whereby a letter grade “A” through “F” is
assigned to an intersection or roadway segment, representing progressively worsening traffic
operations. LOS “A” represents free-flow conditions with little to no delays, while LOS “F”
represents jammed or grid-lock conditions. The roundabout intersection option achieved the
highest LOS of B for the peak-hour traffic, compared to LOS C for the other option. This means
traffic can be expected to perform better with the roundabout, even at the worst hour,
compared to the other alternatives.
Feb. 6, 2023 Item #4 Page 10 of 324
Queuing for all movements at Carlsbad Boulevard and Tamarack Avenue was evaluated against
available storage space. The results for the traffic signal option would exceed the proposed turn
pocket length for the northbound, southbound and westbound left-turn movement during at
least one peak hour under all scenarios. Under the roundabout option, queueing on all
approaches is shown to fit within the available storage space.
As part of a previous outreach, the public expressed concern for the effect of the intersection of
Carlsbad Boulevard and Sequoia Avenue. The left-turn from Carlsbad Boulevard onto Sequoia
Avenue would be closed with the traffic signal option, while it would remain open with the
roundabout intersection option.
According to the US Department of Transportation Federal Highways Administration’s
Roundabouts: An Informal Guide: “Roundabouts may provide environmental benefits if they
reduce vehicle delay and the number and duration of stops compared with an alternative. Even
when there are heavy volumes, vehicles continue to advance slowly in moving queues rather
than coming to a complete stop. This may reduce noise and air quality impacts and fuel
consumption significantly by reducing the number of acceleration/deceleration cycles and the
time spent idling. In general, if stop or yield control is insufficient, traffic through roundabouts
generates less pollution and consumes less fuel than traffic at fixed-time signalized
intersections.”
The roundabout intersection option shows improvement in traffic congestion from the current
intersection condition. As a result, all emissions generated by gasoline vehicle usage would be
reduced. The roundabout allows the normal flow of traffic to continue moving without stopping
and idling at the intersection in nonpeak times, and avoids cold starts and stops, which tend to
generate more emissions compared with just slowing down. Qualitatively, the roundabout is
the superior build alternative from an air quality and greenhouse gas emissions standpoint.
While posted speeds will be the same for both options, the roundabout provides the most
effective speed management since drivers will merge to one lane in each direction followed by
the smaller radius circular motion of the roundabout. Drivers awareness is heightened while
navigating the roundabout due to the yield motions required and the flowing movement.
In addition, the roundabout provides the widest sidewalks for pedestrians and the widest
buffer areas for bike lanes. For the bicyclists that choose to stay within the roadway and enter
the roundabout with the vehicular traffic, vehicle speeds will be dropped enough that they can
position themselves amongst the vehicles (in front or behind) at similar speeds. In comparison,
the traffic signal option provide speed management with bulb-outs/curb extensions at joining
intersections.
When comparing the safety of both options, the roundabout would provide the most dynamic
speed management scenario with the most reduced injury and fatality rate. According to the
Transportation Research Board, or TRB, (2001) and National Cooperative Highway Research
Program, or NCHRP, (2007), the safety improvements provided by the roundabout include:
• More than 90% reduction in fatalities
Feb. 6, 2023 Item #4 Page 11 of 324
• 67% reduction in injuries
• 35% reduction in all crashes
• Slower speeds are generally safer for pedestrians
In addition, according to FHWA (2000) roundabouts reduce the frequency and severity of
crashes by:
• Eliminating the most severe types of crashes– high angle movements including right-
angle, left-turn, and head on collisions
• Decreasing relative speeds approaching and through the intersection. Lower speed is
associated with better yielding rates and reduced vehicle stopping distance
• Minimizing the speed differential of most road users
• Shortening the pedestrian crossing distances and pedestrians only cross one direction of
traffic at a time at each approach
• Decreasing vehicle to vehicle, pedestrian to vehicle and bicycle to vehicle conflict points
Table 1 provides more details and comparison between the traffic signal and roundabout
intersection control options.

Recommendations
Staff have reviewed the intersection control alternatives analysis in detail to evaluate the
feasibility, operational functionality and performance, and safety enhancements for all users for
the Carlsbad Boulevard and Tamarack Avenue intersection. Based on the results staff
recommend the single-lane modern roundabout as the preferred intersection control option.
Based on the community feedback highlighting the desire for better speed management,
alleviating congestion, improved safety for pedestrians and bicyclists, the roundabout option
addresses all these elements the best, while best meeting city policies and standards. The
roundabout option would be the safest option and change the characteristics of the road to
promote improved driver behavior.
Based on the engineering evaluation provided by the design consultant, the roundabout option
provides most efficient traffic operations, safer and shorter pedestrian crossings, better
improvements for bicyclists with respect to bike lane and buffer widths with the ability to either
use the multiuse path or the travel lane, with enhanced coastline experience.
The roundabout option creates the safest intersection scenario of the two options through:
• Reducing vehicle conflicts with pedestrians and bicyclists
• Reducing bike and vehicle speed differentials
• Reducing vehicle speed in general within and approaching the intersection
• Widening the sidewalk to increase pedestrian capacity and comfort
Studies have shown that roundabout intersection significantly reduce the number of serious
collision conflict points and result in a 90% reduction in fatalities compared to signalized
intersections. Additionally, the roundabout was modeled to ensure delivery trucks, trash trucks,
and emergency service vehicles can navigate in all directions through the intersection.
Furthermore, the roundabout option is the more sustainable option compared to a signalized
intersection. This option is the best for financial and environmental sustainability. It will
minimize infrastructure maintenance needs and costs. It will also reduce the air pollution
generated by vehicles and require less electricity and maintenance costs than a signalized
intersection. The roundabout option would require less pavement than the signalized
intersections and this leads to fewer greenhouse gas emissions from the construction and
maintenance and less surface water runoff during rain events. In addition, roundabouts can
reduce noise levels, as the design results in slower speeds through the intersection providing a
notable improvement in local noise pollution and providing residents with a quieter
environment.
It’s for the reasons provided throughout the staff report and based on the engineering and
mobility evaluations and compliance with city plans and policies that staff recommend the
roundabout as the preferred intersection control at Carlsbad Boulevard and Tamarack Avenue.
Next Steps
Following the Traffic & Mobility Commission’s review, staff will present the project to the City
Council with a recommendation to approve the preferred option. Once the preferred
Feb. 6, 2023 Item #4 Page 14 of 324
intersection control option is determined, the project will advance to final engineering design
and environmental review and permitting phase.
Final engineering design and environmental permitting will begin in April 2023 and is estimated
to be completed in early 2025. The project plans and specifications are targeted for approval
and authorization to solicit bids for construction in mid-2025. Staff plan to return to the City
Council with a request to award the construction contract in mid-2025. The construction is
targeted to start in late 2025 and be completed by late 2026, contingent upon coordination
with State Parks and obtaining a Coastal Development Permit.

Alternatives Analysis
INTRODUCTION
This memorandum has been prepared to present an Alternatives Analysis for the proposed Carlsbad
Boulevard and Tamarack Avenue Intersection Improvement Project located in the City of Carlsbad,
California. This analysis evaluates four (4) project alternatives:
·No Build Alternative
·Alternative 1 – Signalized 3-Lane Intersection Alternative
·Alternative 2 – Signalized 4-Lane Intersection Alternative
·Alternative 3 – Roundabout Intersection Alternative
The results of this analysis are based on the city-approved Mobility Analysis, dated December 2, 2022.
PROJECT GOALS AND OBJECTIVES
As determined by the project development team, the City of Carlsbad, and the stakeholders of this project,
the goal of the Carlsbad Boulevard and Tamarack Avenue Intersection Improvement Project is to
accommodate all modes of transportation and improve beach access while promoting active transportation
improvements and speed management at this heavily traveled segment of Carlsbad Blvd to make it safer
for all modes of users. The city council aims to become a leader in multimodal transportation systems,
implementing creative approaches to moving people and goods through and within Carlsbad to enhance
Carlsbad’s coastline and ensure an exceptional experience in all the ways people want to enjoy it. The goal
of the project is to also close a critical gap in the transportation network by improving the bicycle,
pedestrian, and transit environment on Carlsbad Boulevard, thus promoting alternative modes as viable
forms of transportation, and improving safety for users that choose those alternative modes. The project
improvements provide operational enhancements for vehicles, bicycles, pedestrians, and riders consistent
with the city’s General Plan Mobility Element and Climate Action Plan.
Improvement features will include:
·Reconfiguration of the intersection to ease traffic flow
·Widening of the sidewalk, including to the south across the bridge
·Relocating the North County Transit District bus stops to provide safer access
·Improving pedestrian and bike facilities

EXISTING CONDITIONS
STUDY INTERSECTION
This analysis focuses on the intersection of Carlsbad Boulevard and Tamarack Avenue. The project location
and study limits are shown in Figure 1. Carlsbad Boulevard and Tamarack Avenue is currently a signalized
intersection with 10-foot-wide pedestrian crosswalks on the north and east legs. There is a 4-foot-wide
pedestrian refuge island through the north leg crossing. The sidewalk has visible cracks and spalling with
minor settlement and uplift in some areas. The northbound and southbound approaches currently include
protected left-turn phasing and the eastbound and westbound approaches include split phasing. The study
area consists of the following roadway segments that make up the four approaches of the study
intersection:
Carlsbad Boulevard: A four-lane roadway that runs north-south between the city limits. The posted speed
limit is 30 miles per hour (mph) north of Tamarack Avenue and 35 mph south of Tamarack Avenue. Based
on the City of Carlsbad General Plan Mobility Element (Mobility Element), Carlsbad Boulevard is designated
as an Identity Street north of Tamarack Avenue and as a Coastal Street south of Tamarack Avenue. The
southbound approach of the study intersection includes two through lanes, a southbound left-turn pocket,
and a signal-controlled channelized southbound right-split lane. The northbound approach includes two
through lanes and a northbound left-turn pocket.
Tamarack Avenue: Within the study area, Tamarack Avenue is a two-lane roadway with a two-way left-
turn lane that generally runs east-west between Carlsbad Boulevard and College Boulevard. The posted
speed limit is 30 miles per hour (mph) west of Skyline Road and 35 mph east of Skyline Road. Tamarack
Avenue forms the westbound approach of the study intersection and contains one shared through-right
turn lane and a left-turn pocket. Based on the Mobility Element, Tamarack Avenue is designated as a
Neighborhood Connector Street.
Beach Access Road: The Beach Access Road is a local access road that provides access to the Tamarack
State Beach parking lot, owned and operated by California Department of Parks and Recreation, State
Parks. There is no posted speed on this road, however, speeds can be assumed to be 25 mph or less. The
Beach Access Road forms the eastbound approach to the study intersection and contains a shared through-
left turn lane, and a stop-controlled channelized right-turn lane.
ADJACENT INTERSECTIONS
Redwood Avenue: Redwood Avenue is a two-lane east-west local roadway that forms a full access side-
street stop-controlled intersection with Carlsbad Boulevard approximately 300 feet north of Tamarack
Avenue. Redwood Avenue is designated as a “village street” in the Mobility Element.
Sequoia Avenue: Sequoia Avenue is a two-lane east-west local roadway that forms a full access side-street
stop-controlled intersection with Carlsbad Boulevard approximately 300 feet south of Tamarack Avenue.
Sequoia Avenue is designated as a “local/neighborhood street” in the Mobility Element.

PEDESTRIAN, BICYCLE, AND TRANSIT FACILITIES
Existing Pedestrian Facilities
Within the study area, sidewalks exist along both sides of Carlsbad Boulevard and Tamarack Avenue.
Sidewalk along the west side of Carlsbad Boulevard south of Tamarack Avenue is 4 to 5-feet-wide and
buffered by a guardrail. Sidewalk along the west side of Carlsbad Boulevard north of Tamarack Avenue is 8-
feet-wide buffered by a landscaped area. The Carlsbad Boulevard & Tamarack Avenue intersection contains
pedestrian crosswalks with push buttons, countdown signal heads, curb ramps on the north and east legs
of the intersection, and the Agua Hedionda trail head and Coastal Rail Trail facilities in the nearby vicinity.
Existing Bicycle Facilities
The City of Carlsbad General Plan Mobility Element and Carlsbad Bikeway Master Plan references three (3)
bikeway facility types, consistent with Caltrans definitions, as follows:
· Class I Bikeway (bike path) – provides a separated corridor that is not served by streets and
highways and is away from the influence of parallel streets. Class I bikeways are for non-vehicle use
only with opportunities for direct access and recreational benefits, right-of-way for the exclusive
use of bicycles and pedestrians, and cross flow conflicts are minimized.
· Class II Bikeway (bike lane) – provides a delineated right-of-way assigned to bicyclists to enable
more predictable movements, accommodating bicyclists through corridors where insufficient room
exists for side-by-side sharing of existing streets by motorists and bicyclists.
· Class III Bikeway (bike route) – shared facility that serves either continuity to other bicycle facilities
or designates preferred routes through high demand corridors.
Class II bikeways (bike lanes) exist on the following facilities:
· Northbound and southbound Carlsbad Boulevard within the study area.
· Eastbound and westbound Tamarack Avenue within the study area.
Existing Transit Facilities
Transit in the City of Carlsbad includes North County Transit District (NCTD) transit service, Americans
with Disabilities Act (ADA) paratransit service, the COASTER commuter rail, and Amtrak rail service. Bus
stops exist within the immediate study area on northbound Carlsbad Boulevard, approximately 170 feet
north of Tamarack Avenue, and on southbound Carlsbad Boulevard within the porkchop island on the west
leg of the intersection. Both stops contain signage and benches, however, there are currently no ADA-
compliant pedestrian facilities providing access to the stop on southbound Carlsbad Boulevard. The bus
stops are serviced by Route 101 of the NCTD (referred to as the “BREEZE”). Currently, Route 101 provides
service along Highway 101 between Oceanside Transit Center in Oceanside and UTC Transit Center in San
Diego. Service is provided seven days a week with approximately 30-minute headways throughout the day
and hourly headways in the evenings.
CONCEPTUAL ALTERNATIVES
PROPOSED ALTERNATIVES
This analysis studies the following four project alternatives:
No Build Alternative: This alternative presents a baseline condition in which no improvements would be
made to the study intersection and corridor.
Signalized 3-Lane Intersection Alternative: As seen on the attached Alternative 1 exhibit, this alternative
represents a signalized condition in which the following improvements would be made:
Feb. 6, 2023 Item #4 Page 20 of 324
Final Carlsbad Boulevard and Tamarack Avenue Intersection Improvement Project Alternatives Analysis 5 of 27
· New striping along Carlsbad Boulevard between Hemlock Avenue and just south of the Agua
Hedionda Lagoon bridge, along Tamarack Avenue approximately 175 feet east of Carlsbad
Boulevard, and along the Beach Access Road approximately 100 feet west of Carlsbad Boulevard.
· Addition of high visibility pedestrian crossings on all four legs of the study intersection and on the
east leg of the Carlsbad Boulevard & Sequoia Avenue intersection.
· Addition of green bike lane conflict zone striping that highlights the presence of bicyclists.
· Bulb-outs/curb extensions with directional curb ramps at the southeast corner of Carlsbad
Boulevard/Tamarack Ave intersection and east leg of the Carlsbad Boulevard/Sequoia Avenue
intersection.
· A parking lane and pull-out bus stop alongside a buffered bike lane on the west side of Carlsbad
Boulevard north of Tamarack Avenue.
· A pull-out bus stop on the east side of Carlsbad Boulevard south of Tamarack Avenue alongside a
bike lane.
· 6-ft bike lane without a buffer on the east side of Carlsbad Boulevard north of Tamarack Avenue to
Hemlock Avenue.
· 6-ft bike lane with a 2-ft buffer on both sides of the bike lane (with adjacent on-street parking) on
the west side of Carlsbad Boulevard north of Tamarack Avenue.
· 6-ft bike lane without a buffer on the west side of Carlsbad Boulevard south of Tamarack Avenue
for approximately 420 feet which then transitions to an 8-ft bike lane with a 3-ft buffer as it
continues south, ending south of the Agua Hedionda Lagoon bridge.
· 6-ft bike lane without a buffer on the east side of Carlsbad Boulevard between Tamarack Avenue
and Sequoia Avenue, followed by a 6-ft bike lane with a 2-ft buffer south of Sequoia Avenue to the
project limits south of the Agua Hedionda Lagoon bridge.
· 7-ft bike lane on both sides of Tamarack Avenue
· 10-ft western sidewalk to the north of Tamarack Avenue provided for the length of the proposed
bus stop only, as there is already an existing meandering sidewalk that would remain in place.
· Existing 5-ft eastern sidewalk would remain in place to the north of Tamarack Avenue.
· 9-ft western sidewalk to the south of Tamarack Avenue, which would then widen to 11 feet to the
south followed by a maximum 15.5-ft width on the bridge.
· 10-ft eastern sidewalk between Tamarack Avenue and Sequoia Avenue followed by a 5 to 6-ft
eastern sidewalk south of Sequoia Avenue.
· A new signalized midblock pedestrian crossing on Carlsbad Boulevard approximately 680 feet
south of the study intersection with ADA curb ramps.
· New directional ADA curb ramps at all pedestrian crossings within the study intersection and on
the east leg of the Carlsbad Boulevard & Sequoia Avenue intersection. All other curb ramps at
adjacent intersections would remain protected in place.
· One 10.5-ft to 11-ft through lane and one 10.5-ft to 11-ft through-right lane in the northbound
direction
· One 10-ft to 10.5-ft through lane and one 10-ft to 10.5-ft through-right lane in the southbound
direction
· A single 10-ft northbound and southbound exclusive left-turn lane
· 11-ft through lanes on Tamarack Avenue in both eastbound and westbound directions
· 11-ft left-turn lane on Tamarack Avenue
· Exclusive and separated 20-ft right-turn lane from Beach Access Road to southbound Carlsbad
Boulevard, separated by a median with a Caltrans Type C Island Passageway.
· A single through and receiving lane on the Beach Access Road of varying widths

Final Carlsbad Boulevard and Tamarack Avenue Intersection Improvement Project Alternatives Analysis 6 of 27
· Removal of the southbound channelized right-split lane and conversion of one southbound through
lane to a shared-through right lane.
· Reduction of southbound Carlsbad Boulevard to one lane just north of the proposed midblock
crossing with the merge taper beginning approximately 420 feet south of the Carlsbad
Blvd/Tamarack Ave intersection.
· Signal modification to include pedestrian phases for the west and south legs. The signal is assumed
to remain actuated uncoordinated.
Under the Signalized 3-Lane Intersection Alternative, the intersection of Carlsbad Boulevard and Redwood
Avenue would remain full-access, however, the intersection of Carlsbad Boulevard and Sequoia Avenue
would be converted to right-in/right-out only.
Signalized 4-Lane Intersection Alternative: As seen on the attached Alternative 2 exhibit, this alternative
represents a signalized condition that consists of almost all the improvements included in the Signalized 3-
Lane Intersection Alternative but omits the lane reduction on southbound Carlsbad Boulevard south of
Tamarack Avenue. Carlsbad Boulevard would remain a 4-lane corridor throughout the project limits. Due
to the inclusion of the 4th lane, the western sidewalk to the south of Tamarack Avenue, would widen to a
maximum 11-ft width to the south. Additionally, the southbound bike lane south of Tamarack Avenue
would be 6 feet wide without a buffer. All other lane, sidewalk, and bike lane widths would remain the
same as the Signalized 3-Lane Intersection Alternative.
Roundabout Intersection Alternative: As seen on the attached Alternative 3 exhibit, this alternative
proposes many improvements similar to the Signalized 3-Lane Intersection Alternative but with additional
buffered bike lanes, wider sidewalks, and would construct a single lane roundabout at the study
intersection. In the southbound direction, a lane would be dropped starting just south of Cherry Avenue
and would open back to two through lanes south of the Agua Hedionda Lagoon bridge. In the northbound
direction, a lane would be dropped south of the Agua Hedionda Lagoon bridge and would open back to two
through lanes north of Hemlock Avenue. This alternative proposes the following additional differentiators
from the Signalized 3-Lane Intersection Alternative:
· An additional high visibility crosswalk on the east leg of Redwood Avenue.
· ADA directional curb ramps at all pedestrian crossings within the roundabout
· 8-ft bike lane with a 3-ft buffer on the east side of Carlsbad Boulevard north of Tamarack Avenue to
Hemlock Avenue.
· 8-ft bike lane with a 3-ft buffer on both sides (with adjacent on-street parking) on the west side of
Carlsbad Boulevard north of Tamarack Avenue.
· 8-ft bike lane with a 3-ft buffer on the west side of Carlsbad Boulevard south of Tamarack Avenue.

· 7-ft bike lane with a 3-ft buffer on the east side of Carlsbad Boulevard between Tamarack Avenue
and Sequoia Avenue, followed by an 8-ft bike lane with a 3-ft buffer south of Sequoia Avenue to the
project limits south of the Agua Hedionda Lagoon bridge.
· 10-ft western sidewalk to the north of Tamarack Avenue. Existing meandering sidewalk would
remain in place.
· 9.2 to 10-ft eastern sidewalks to the north of Tamarack Avenue.
· 14-ft western sidewalk to the south of Tamarack Avenue, which would then widen to 16 feet to the
south followed by a 15-ft sidewalk width on the bridge.
· 10-ft eastern sidewalk between Tamarack Avenue and Sequoia Avenue followed by an 11-ft eastern
sidewalk south of Sequoia Avenue, which widens to 14 feet to the south followed by a 13-ft
sidewalk width on the bridge.
· 10.5-ft to 11-ft single through lane on southbound Carlsbad Boulevard, which would then widen as
it approaches the roundabout.
· 11-ft single through lane on northbound Carlsbad Boulevard, which would then widen as it
approaches the roundabout.
· 17-ft single lane within the roundabout.
· Truck apron interior circle of the roundabout.
· Additional truck apron in the southeast corner of the roundabout.
· 10-ft medians on Carlsbad Boulevard both north and south of the roundabout.
· 11-ft eastbound through lane and westbound through lane on Tamarack Ave, each of which would
widen as it approaches the roundabout.
· 11.5-ft eastbound lane and 10-ft westbound lane within the Beach Access Road, each of which
would widen as it approaches the roundabout.
· Exclusive and separated 22-ft right-turn lane from Beach Access Road to southbound Carlsbad
Boulevard, separated by a median with a Caltrans Type C Island Passageway.
· Varying width medians on Tamarack Avenue and the Beach Access Road.
· Additional landscaping around roundabout perimeter.
· The intersection improvements will include conduit to facilitate each leg and pedestrian crossings
could be signalized in the future as needed to address operational issues.
This alternative assumes installation of a metering signal on the eastbound approach (west leg) with queue
detection on the northbound approach (south leg) located approximately 500 feet south of the yield line.
This means the vehicles approaching the roundabout from the Beach Access Road will be metered in a
similar fashion to a freeway on-ramp to ensure the queue on Carlsbad Boulevard is clearing the
intersection. The intersections of Carlsbad Boulevard with Redwood Avenue and Sequoia Avenue would

remain full access.
The three conceptual project alternatives are shown in Appendix A.
ALTERNATIVES ANALYSIS PROCESS
This section details the alternatives and criteria to meet the goals defined by the City of Carlsbad and all
modes of transportation needs in a multi-step screening process as shown in the figure below.
PEDESTRIAN, BICYCLE, AND TRANSIT ENHANCEMENTS
One of the main goals of this project is to enhance the public facilities provided for pedestrians and
bicyclists. For pedestrians, this means creating wide and spacious sidewalks for pedestrians to both walk
alongside each other while also being able to stop and admire the coastline.
Implementing curb extension at the corners of the intersection will enhance pedestrian safety by
increasing pedestrian visibility and slowing vehicles. Curb extensions increase overall visibility by aligning
pedestrians with the parking lane and by reducing the crossing distance for pedestrians. By physically and
visually narrowing the roadway, vehicles are encouraged to slow down.
For bicyclists, this means providing bike lanes with buffers to separate bicyclists from vehicular traffic for
an added level of safety. When the bike lane runs adjacent to the on-street parking, a buffer between the
parking lane and the bike lane is also preferred. Bike lane widths should be a minimum of 6 feet, but 8 feet
is preferred to provide bicyclists with plenty of space to ride without providing so much width that a motor
vehicle could mistake the bike lane for a traffic lane.
For transit, this means providing near-side pull-out bus stop configurations. Near-side pull out stops
benefit traffic flow by not blocking the through lane while buses are stopped at the station. Safety is also
improved since transit riders come from the font, which is more visible to the transit operator. Pedestrian
enhancements will also benefit transit users, as wider sidewalks provide additional space for waiting riders
in addition to space for bus stop amenities.
To evaluate the pedestrian and bicycle enhancements, the Mobility Analysis performed for this project
determined the Multimodal Level of Service (MMLOS) for pedestrians and bicyclists. MMLOS provides a
qualitative “grade” assigned to specified travel modes, ranging from a LOS A to LOS F. As outlined in the
city’s General Plan, LOS A reflects a high service standard for a travel mode (e.g., outstanding

characteristics and experience for that mode) and LOS F reflects a poor service standard for a travel mode
(e.g. congestion for vehicles, no bicycle, pedestrian, or transit facilities, etc.)
MMLOS evaluates the safety and quality of access and mobility for pedestrian, bicyclist, and transit users
using methods documented in the Carlsbad General Plan Mobility Element, Chapter 3. The City of Carlsbad
MMLOS Tool takes into account inputs such as sidewalk and bike lane widths, speed limit, presence of
pedestrian and bike lane buffers, and speed management features such as bulb-outs and high visibility
crosswalks. Per Policy 3-P.4 in the General Plan Mobility Element, the study area pedestrian and bicycle
facilities should maintain LOS D or better. As published in Table 3-1 of the city’s General Plan, Transit is not
subject to a MMLOS standard.
Pedestrian and Bicycle MMLOS for the three main approaches of the Carlsbad Boulevard and Tamarack
Avenue intersection, as well as the segment of Carlsbad Boulevard between Sequoia Avenue and the south
end of the bridge, were evaluated for all alternatives under Existing conditions. Cumulative and Horizon
Year scenario analysis was omitted because Cumulative ADT volumes showed only a very slight increase
over Existing ADTs and projected Horizon Year ADTs were lower than Existing ADTs. As such, Horizon Year
and Cumulative condition MMLOS results were projected to be the same as Existing MMLOS results.
Pedestrian LOS for the segment of Carlsbad Boulevard between Sequoia Avenue and the south end of the
bridge is better under the Signalized 3-Lane Intersection Alternative and Roundabout Alternative than
under the 4-Lane Alternative, as the roadway would be narrower at the midblock crossing, allowing
pedestrians to cross fewer lanes. Table 1 shows the pedestrian and bicycle scores and LOS for each
direction of the study segments. As shown in Table 1, all three proposed project alternatives were found
to provide notably better pedestrian LOS and similar or better bicycle LOS over No Build conditions. See
Appendix D for the MMLOS Worksheets used to determine these results.
In addition to the MMLOS analysis, it should be noted that each alternative provides different pedestrian
and bicycle facilities. As noted in the alternative descriptions, these are:
· Pedestrian Facilities:
o No Build Alternative – Existing sidewalks are approximately 5 to 6 feet wide throughout the
project area, except on the west side of Carlsbad Boulevard south of Tamarack Avenue
where the sidewalk has metal beam guardrail followed by a barrier along the bridge, which
shrinks the sidewalk to 4 to 5 feet. Additionally, there is no curb-adjacent sidewalk on the
west side of Carlsbad Boulevard to the north of Tamarack Avenue; which instead has an
offset meandering sidewalk 8 feet wide. Crosswalks exist only on the north and eastern leg
of the Carlsbad Boulevard and Tamarack Avenue intersection with a maximum crossing
width of 76 feet.
o Signalized 3-Lane Intersection Alternative – Proposed sidewalks on the west side of
Carlsbad Boulevard to the north of Tamarack Avenue, and on the east side to the south
between Tamarack Avenue and Sequoia Avenue, are 10 feet wide. The existing 5-ft sidewalk
on the east side of Carlsbad Boulevard to the north of Tamarack Avenue would remain
protected in place. The proposed sidewalk on the west side of Carlsbad Boulevard to the
south of Tamarack Avenue is 9 feet minimum to 16 feet maximum. And the proposed
sidewalk on the east side of Carlsbad Boulevard to the south of Sequoia Avenue is 5 feet
minimum to 6 feet maximum. Crosswalks and directional curb ramps are proposed on all
legs of the intersection with a maximum crossing width of 65 feet. A Caltrans Type C Island
Passageway is proposed within the median island separating the exclusive right-turn lane
coming from the Beach Access Road.
o Signalized 4-Lane Intersection Alternative – Proposed sidewalks are the same as the
Signalized 3-Lane Intersection Alternative except on the west side of Carlsbad Boulevard to
the south of Tamarack Avenue: here they are 9 feet minimum to 11 feet maximum.
Proposed crosswalks are the same as the Signalized 3-Lane Intersection Alternative.
Feb. 6, 2023 Item #4 Page 25 of 324
Final Carlsbad Boulevard and Tamarack Avenue Intersection Improvement Project Alternatives Analysis 10 of 27
o Roundabout Alternative – Proposed sidewalks on the west side of Carlsbad Boulevard to the
north of Tamarack Avenue, on the east side to the north between Tamarack Avenue and
Redwood Avenue, and on the east side to the south between Tamarack Avenue and Sequoia
Avenue are 10 feet wide. On the east side of Carlsbad Boulevard to the north of Redwood
Avenue, the proposed sidewalk is 9.2 feet wide. Proposed sidewalk on the west side of
Carlsbad Boulevard to the south of Tamarack Avenue is 14 feet minimum to 16 feet
maximum. And the proposed sidewalk on the east side of Carlsbad Boulevard to the south of
Sequoia Avenue is 11 feet minimum to 14 feet maximum. Crosswalks are proposed on all
legs of the roundabout with median refugee island further reducing the maximum crossing
width to 22 feet. Each median refugee island includes a Caltrans Type A or B passageway. A
Caltrans Type C Island Passageway is proposed within the median porkchop separating the
exclusive right-turn lane coming from the Beach Access Road.
· Bicycle Facilities:
o No Build Alternative – The existing bike lane on the west side of Carlsbad Boulevard to the
north of Tamarack Avenue is 6.5 to 7.5 feet wide with no buffer. The existing bike lane on
the east side of Carlsbad Boulevard to the north of Tamarack Avenue is 5 to 7 feet wide with
no buffer. The existing bike lane on the west side of Carlsbad Boulevard to the south of
Tamarack Avenue is approximately 7 feet wide with a 2-ft buffer that widens to a 5-ft buffer
over the bridge. And the existing bike lane on the east side of Carlsbad Boulevard to the
south of Tamarack Avenue is approximately 7 feet wide with a varying buffer that widens to
5 feet over the bridge. Bicyclists and vehicles have 65 potential conflict points.
o Signalized 3-Lane Intersection Alternative - All 6-ft bike lanes, sometimes with 2-ft buffers
and sometimes without buffers, with a 3-ft buffer for the southbound bike lane over the
Agua Hedionda Lagoon bridge. Bicyclists and vehicles have 69 potential conflict points.
o Signalized 4-Lane Intersection Alternative – All 6-ft bike lanes, half with 2-ft buffers and half
without buffers. This alternative has the same number of potential bike and vehicle conflicts
as the Signalized 3-lane intersection Alternative.
o Roundabout Alternative – All 8-ft bike lanes with 3-ft buffers, except alongside the adjacent
parking where the bike lane is 7 feet with a 3-ft buffer on both sides. Bicyclists and vehicles
have 27 potential conflict points, which is about 50% fewer conflict points compared to a
signal-controlled intersection.
· Transit Facilities:
o No Build Alternative – The existing bus stop in the southbound direction of Carlsbad
Boulevard is located within the median island refuge at the southwest corner of the
Carlsbad Boulevard and Tamarack Avenue intersection. The pedestrian access ramp is not
ADA-compliant and does not connect to the pedestrian traveled path. When stopped at this
station, the bus is within the 8-foot bike lane and forces bicyclists into the vehicle lane to
bypass the stopped bus, introducing a major conflict point. The existing bus stop in the
northbound direction is located 120 feet north of the Carlsbad Boulevard and Tamarack
Avenue intersection and located 5 feet from a driveway. The sidewalk is 5 feet wide which
does not meet the minimum ramp deployment area (FHWA, 2015). When stopped at this
station the bus will be within both the bike lane and vehicle lane, causing cars to stop or
make unsafe maneuvers around the stopped bus.
o Signalized 3-Lane Intersection Alternative – Relocates bus stops to a near side
configuration. 8-ft wide bus station pull out with 80-foot-long and 10-foot-wide bus station.
Along the length of the bus pull-out is a 6-foot-wide high visibility green painted bike lane
with a 2-foot buffer on both sides.
o Signalized 4-Lane Intersection Alternative – Same transit enhancements as Signalized 3-
lane Intersection Alternative.
Feb. 6, 2023 Item #4 Page 26 of 324
Final Carlsbad Boulevard and Tamarack Avenue Intersection Improvement Project Alternatives Analysis 11 of 27
o Roundabout Alternative – 8-ft wide bus station pull out with 80-foot-long and 10-foot-wide
bus station. Along the length of the bus pull-out is a 7-ft high visibility green painted bike
lane with a 3-foot buffer on both sides.
Although the three proposed alternatives all provide clear enhancements to the pedestrian, bicycle, and
transit facilities compared to the No Build Alternative, the differences between the alternatives should be
noted. The roundabout provides significant benefits over the two signalized alternatives, including shorter
crossing distances, slower traffic speed, and lower number of potential conflict points. For sidewalk
facilities, where the signalized alternatives maintain existing 5-ft sidewalks on the east side to the north of
the intersection and proposed 5-ft sidewalks south of Sequoia Avenue on the east side, the roundabout
replaces these with much wider 10-ft and 11 to 14-ft widths, respectively. Additionally, on the west side
south of the intersection, the roundabout provides sidewalk widths between 14 to 16 feet, the signalized 3-
Lane intersection alternative provides 9 to 16 feet, and the 4-lane provides 9 to 11 feet. In a populated and
heavily traveled segment of a beachside location such as this, maximizing these widths is of extreme
importance.

TRAFFIC IMPACTS AND PERFORMANCE
The Mobility Analysis performed for this project evaluated the following scenarios using the Traffic Counts
included in Appendix B:
• Existing Conditions: Existing traffic volumes from counts taken in May and June of 2022 on
Thursday’s and Saturday’s. These traffic counts are provided in Appendix B.
• Cumulative Conditions: A near-term scenario representing existing traffic volumes plus traffic
projected to be generated from approved and reasonably foreseeable pending projects that are
expected to influence the study area and intersection.
• Horizon Year 2035 Conditions: a future year scenario based on growth found in the
Transportation Forecast Information Center (TFIC) as part of the San Diego Association of
Governments (SANDAG) ABM2+/2021 Regional Transportation Demand Model (RTDM).
The study intersection was evaluated under the following time periods:
• Typical Weekday AM peak hour
• Typical Weekday PM peak hour
• Summer Weekend (Saturday) midday peak hour
Level of Service
Traffic operations were quantified through the determination of “Level of Service” (LOS). Level of Service is
a qualitative measure of traffic operating conditions, whereby a letter grade “A” through “F” is assigned to
an intersection or roadway segment, representing progressively worsening traffic operations. LOS “A”
represents free-flow conditions with little to no delays, while LOS “F” represents jammed or grid-lock
conditions. For the Mobility Analysis performed, it was assumed that city roadways and intersections
should strive to maintain LOS D or better operations during peak periods, when possible.
Intersection LOS results are shown in Table 2 below for all alternatives and scenarios. As shown in Table
2, the study intersection would operate at LOS C or better under all scenarios.

Queuing
95th Percentile queuing for all movements at Carlsbad Boulevard and Tamarack Avenue was evaluated
against existing and proposed available storage space using SimTraffic for signalized intersection control
and Sidra software for roundabout control. Storage space for turn lanes was based on turn pocket length
and storage space for through movement was based on the distance to the nearest cross street.
Table 3 below shows the 95th percentile queueing at each movement compared to the available storage
length.

Notes:
Bold values indicate queues that exceed storage length.
1Storage reported is available queueing length within a turn pocket or the length of a through lane before nearest conflicting cross-
street.
2 Where multiple lanes exist for one movement, queue reported is the highest for that movement.
3 Movement abbreviations are as follows: Northbound (NB), Northbound Left (NBL), Northbound Through (NBT), Southbound (SB),
Southbound Left (SBL), Southbound Right (SBR), Southbound Through (SBT), Eastbound (EB), Eastbound Through (EBT), Eastbound
Right (EBR), Westbound (WB), Westbound Left (WBL), Westbound Through (WBT).
As shown in Table 3, under the Signalized 3-Lane and 4-Lane Intersection Alternatives, queueing would
exceed the proposed turn pocket length for the northbound, southbound, and westbound left-turn
movement during at least one peak hour under all scenarios. Minimum turn pocket lengths to
accommodate maximum projected left-turn queues under the Signalized 3-Lane and 4-Lane Intersection
Alternatives are as follows:
Feb. 6, 2023 Item #4 Page 31 of 324
Final Carlsbad Boulevard and Tamarack Avenue Intersection Improvement Project Alternatives Analysis 16 of 27
· Northbound Left-Turn:
o Signalized 3-Lane Intersection Alternative: 135 feet
o 4-Lane Alternative: 140 feet
Proposed northbound left-turn queue lengths for the signalized alternatives can be
maximized to 150 feet. The additional length would take some width from the
western sidewalk; however, if selected this change would be implemented in final
design.
· Southbound Left-Turn:
o Signalized 3-Lane Intersection Alternative: 215 feet
o Signalized 4-Lane Intersection Alternative: 195 feet
Proposed southbound left-turn queue lengths for the signalized alternatives were
maximized at 97 feet. This length cannot be increased without removing access from
southbound Carlsbad Boulevard to Redwood Avenue.
· Westbound Left-Turn (from Tamarack Avenue):
o Signalized 3-Lane Intersection Alternative: 180 feet
o Signalized 4-Lane Intersection Alternative: 175 feet
Proposed left-turn queue lengths for the signalized alternatives were maximized at
93 feet. This length cannot be increased without acquisition of right of way from
adjacent properties.
Northbound and southbound queueing are projected to exceed available storage during at least one peak
hour for all scenarios under the Signalized 3-Lane and 4-Lane Intersection Alternatives. Worst-case
southbound queues under the Signalized 3-Lane Intersection Alternative would be 348 feet long (back of
queue would pass Redwood Avenue). Worst-case southbound queues under the 4-Lane Alternative would
be 272 feet long and are projected to be better than those under the Signalized 3-Lane Intersection
Alternative since the lane reduction of southbound Carlsbad Avenue south of Tamarack Avenue would not
occur under this Alternative.
Worst-case northbound queues are projected to be 539 feet and 536 feet long under the 3-Lane and 4-Lane
Alternatives, respectively, reaching back to the northern end of the Agua Hedionda Lagoon bridge. As the
intersection of Sequoia Avenue and Carlsbad Boulevard would be converted to right-in/right-out only
under these Alternatives, no queueing-related improvements are recommended at the Carlsbad Boulevard
& Sequoia Avenue intersection. Note that under worst-case conditions, both the northbound and
southbound queues were observed to clear the intersection in one cycle.
Under the Roundabout Alternative, queueing on all approaches is shown to fit within the available storage
space.
Eastbound (from beach parking driveway) shared left/through queueing is projected to fit within available
storage under all scenarios and alternatives. Eastbound right-turn queueing is shown to slightly exceed the
short, channelized right-turn pocket during the Existing Summer Saturday Peak Hour for the 4-Lane
Alternative. However as there is additional storage space along the drive aisle before reaching the beach
parking lot, queue storage is assumed to be adequate for this approach under all scenarios and alternatives.
Queueing at Redwood Avenue and Sequoia Avenue
As part of a previous outreach, the public expressed concern for the effect of the project alternatives on
queueing at the intersections of Carlsbad Boulevard with Redwood Avenue and Sequoia Avenue. These
potential queueing impacts were thus evaluated as part of the Mobility Analysis. Redwood Avenue is
proposed to remain full-access under all alternatives and Sequoia Avenue is proposed to be converted to
right-in/right-out only under the 3-Lane and 4-Lane Alternatives.
Results showed that maximum westbound and southbound left-turn queues at Redwood Avenue would
both fit within available storage space. At Sequoia Avenue, results showed that maximum westbound
Feb. 6, 2023 Item #4 Page 32 of 324
Final Carlsbad Boulevard and Tamarack Avenue Intersection Improvement Project Alternatives Analysis 17 of 27
queues are projected to fit within available storage space. As worst-case northbound left-turn queueing at
Carlsbad Boulevard and Tamarack Avenue is projected to be 137 feet, there may not be enough space to
retain the southbound left-turn pocket at Sequoia Avenue under the 3-Lane and 4-Lane Alternatives.
Therefore, it is recommended that Sequoia Avenue operate with right-in/right-out control under the 3-
Lane and 4-Lane Alternatives as proposed.
Since there would be no northbound left-turn pocket at the Carlsbad Boulevard and Tamarack Avenue
intersection under the Roundabout Alternative, there would be adequate room to provide a southbound
left-turn pocket at Sequoia Avenue under the Roundabout Alternative. Maximum 95th percentile
southbound left-turn queues at Sequoia Avenue are projected to be 25 feet, which fits within available
storage.
ENVIRONMENTAL CONSTRAINTS
Biological Resources
Early evaluation of the Biological Study Area and record searches of the surrounding areas identified
disturbed coastal sage scrub habitat that exists in a small strip between Carlsbad Boulevard and Tamarack
State Beach. There is potential for special status plant species in the project area based on the available
coastal habitat types present. The No Build Alternative would result in no changes to the Biological Study
Area. Each of the three build alternatives have potential to result in small, sliver impacts to adjacent
habitat; however, the City of Carlsbad is committed to minimizing or avoiding impacts wherever feasible,
and mitigating impacts when necessary. At this stage of the alternatives analysis, there is no substantive
difference in the anticipated impacts to biological resources between the three build alternatives.
Cultural Resources
Review of cultural records and coordination with State Parks identified one built environmental cultural
resource in the project area. State Parks has previously evaluated the Tamarack Beach Comfort Station
building and determined that it should be considered eligible for inclusion on the National Register of
Historic Places. None of the build alternatives are expected to result in direct or indirect impacts to the
Comfort Station. Additional coordination with local Native American groups and State Parks relating to the
protection of cultural and historic properties will occur during the environmental document phase of the
project.
Air Quality/Greenhouse Gas Emissions
The data from the Mobility Analysis performed for this project allows for a qualitative analysis of long term
air quality emissions as a result of the three build alternatives, when compared with the No Build
Alternative. Vehicle emissions are generated proportionately with gasoline usage and gasoline usage is
affected by changes in Vehicle Miles Traveled (VMT) and Vehicle Hours Traveled (VHT). Since this is an
intersection improvement project, no new trips are expected to be generated as a result of this project.
Table 2 above shows that none of the proposed alternatives would result in failing Level of Service so no
cut-through traffic or vehicles detouring around the intersection as a result of traffic congestion are
expected. As a result, this alternatives evaluation considers that each of the four alternatives would have
the same VMT.
According to the US Department of Transportation Federal Highways Administration’s Roundabouts: An
Informal Guide: “Roundabouts may provide environmental benefits if they reduce vehicle delay and the
number and duration of stops compared with an alternative. Even when there are heavy volumes, vehicles
continue to advance slowly in moving queues rather than coming to a complete stop. This may reduce noise
and air quality impacts and fuel consumption significantly by reducing the number of
acceleration/deceleration cycles and the time spent idling. In general, if stop or yield control is insufficient,
traffic through roundabouts generates less pollution and consumes less fuel than traffic at fixed-time
signalized intersections.”
Feb. 6, 2023 Item #4 Page 33 of 324
Final Carlsbad Boulevard and Tamarack Avenue Intersection Improvement Project Alternatives Analysis 18 of 27
VHT is directly affected by level of service and delay. When considering the three build alternatives and
comparing them to the No-Build Alternative, the 3-Lane and 4-Lane Alternatives provide variation in delay
depending on the turn movement and time of day. As shown in Table 3 above, some delay values show
improvement, and some are worse when compared to the No Build Alternative. If these signalized
alternatives are selected, additional qualitative modeling is recommended to provide a more detailed
representation of changes in air quality and greenhouse gas emissions that would occur in comparison
with the No Build Alternative. The Roundabout Alternative shows improvement in delay and traffic
congestion across the board when compared with the No Build Alternative. As a result, all emissions
generated by gasoline vehicle usage would be improved with this alternative. Furthermore, the roundabout
allows the normal flow of traffic to continue moving without stopping and idling at the intersection in non-
peak times, which further would reduce VHT and avoids cold starts and stops which tend to generate more
emissions compared with just slowing down. Qualitatively, the roundabout is the superior build alternative
from an air quality and greenhouse gas emissions standpoint.
SAFETY
Collisions and Conflict Points
This section discusses the collision history in the vicinity of the study intersection and safety impacts of the
different alternatives. Approximately fourteen years of crash data (January 2008 – July 2022) were
provided by the city (included in Appendix E) to identify high collision locations and common collision
characteristics. Table 4 summarizes the collisions in the study area, including the collision severity (fatal,
serious injury, other visible injury, complaint of pain, and property damage only (PDO)), the collision type
(broadside, sideswipe, rear-end, hit object), the cause of the collision (driving under the influence, unsafe
speed, improper turning, etc.), and the modes of transportation involved in the incident (vehicle to vehicle,
vehicle to bicyclist, and vehicle to pedestrian).

As shown in Table 4, the majority of collisions occurred at the intersection of Carlsbad Boulevard and

primary collision factors were driving under the influence, unsafe speed, improper turning, traffic signals

and signs, and unsafe starting or backing. Implementation of speed management measures proposed in the
project improvement alternatives would potentially help reduce the number of collisions caused by unsafe
speed and improper turning.
When comparing the safety of the three proposed alternatives, the roundabout would provide the most
dynamic speed management scenario with the most reduced injury and fatality rate. According to the
Transportation Research Board (TRB) (2001) and National Cooperative Highway Research Program
(NCHRP) (2007), the safety improvements provided by the roundabout include:
· More than 90% reduction in fatalities
· 67% reduction in injuries
· 35% reduction in all crashes
· Slower speeds are generally safer for pedestrians
In addition, according to FHWA (2000) roundabouts reduce the frequency and severity of crashes by:
· Eliminating the most severe types of crashes– high angle movements including right-angle, left-
turn, and head on collisions.
· Decreasing relative speeds approaching and through the intersection. Lower speed is associated
with better yielding rates and reduced vehicle stopping distance.
· Minimizing the speed differential of most road users
· Shortening the pedestrian crossing distances and pedestrians only cross one direction of traffic at a
time at each approach.
· Decreasing vehicle to vehicle, pedestrian to vehicle, and bicycle to vehicle conflict points
The frequency of crashes at an intersection is related to the number of conflict points at an intersection as
well as the magnitude of conflicting flows at each conflict point. A conflict point is a location where the
paths of two vehicles, a vehicle and bicycle, or a vehicle and pedestrian diverge, merge, or cross each other.
Fewer conflict points means fewer opportunities for collisions. The severity of a collision is determined
largely by the speed of
impact and the angle of
impact. The higher the
angle and higher the
speed, the more severe
a collision.

Figure 7. Pedestrian to vehicle conflict point comparison for conventional intersection and single lane approach
roundabout (FHWA, 2000).
A pedestrian is three times more likely to die when struck at 30 mph than at 20 mph, a difference of only 10
mph in speed. Typical commuter bicyclists’ speeds are in the range of 12 to 15 mph. Therefore, the
difference in speed is critical to all users. The minor additional delay or inconvenience to drivers of lower-
speed roundabout designs (as compared to higher-speed roundabout designs) is a tradeoff for the

approach roundabout (FHWA, 2000).
Feb. 6, 2023 Item #4 Page 36 of 324

substantial safety benefit to pedestrians and bicyclists. Older drivers may benefit from the additional time
to perceive, think, react, and correct for errors, as may all users (FHWA, 2000).
Speed Management Methods
While posted speeds will be the same for all alternatives, the roundabout provides the most effective speed
management of the proposed alternatives by forcing drivers to merge to one lane in each direction
followed by the smaller radius circular motion of the roundabout. Drivers must be more aware to navigate
the circular motion, as they are forced to slow down.
In addition, the roundabout provides the widest sidewalks for pedestrians and the most buffer areas for
bike lanes. It also forces bicyclists to slow down to enter 5-foot-wide bike ramps angled at approximately
45 degrees to their direction of travel before joining with pedestrians in the sidewalk. For the bicyclists
that choose to stay within the roadway and enter the roundabout with the vehicular traffic, vehicle speeds
will be dropped enough that they can position themselves amongst the vehicles (in front or behind) at
similar speeds.
In comparison, the Signalized 3-Lane and 4-Lane Intersection Alternatives provide speed management
through the use of bulb-outs/curb extensions at joining intersections as well as some widening of
sidewalks and some buffers for bike lanes (similar to the existing condition). These two alternatives
provide the same sidewalk and bike lane improvements throughout except in the southbound direction
south of Tamarack Avenue, where space from the lane drop is given to these other facilities.
This lane drop in the southbound direction provides an additional speed management measure for the
Signalized 3-Lane Intersection Alternative. As vehicles merge to one lane going southbound, they may also
be forced to stop at the signalized pedestrian crossing with high visibility crosswalk prior to the bridge.
Although the Signalized 4-Lane Intersection Alternative also has this crossing, the two lanes heading
southbound won’t be forced to slow down prior to the pedestrian signal. The Signalized 4-Lane
Intersection Alternative is likely to produce vehicles traveling at the fastest speeds in the southbound
direction. In addition, this pedestrian crossing in the Signalized 4-Lane Intersection Alternative has the
longest crossing distance of the three proposed alternatives, making it the least safe crossing of the three.
In the northbound direction, the Signalized 3-Lane and 4-Lane Intersection Alternatives are the same and
will therefore produce the same vehicle speeds. Both signalized alternatives, however, improve sidewalk
and bicycle facilities over existing conditions, and therefore still provide a safer intersection and corridor
compared to the No Build Alternative.
BEACH ACCESS
As discussed in the Safety section above, all three proposed build alternatives provide safety improvements
for pedestrians and bicyclists, and since many will be visiting the coastline and the beach, this means a
safer route for beach access as well. As noted above, all three build alternatives improve access for
pedestrian and bicyclists, but the roundabout alternative provides the safest scenario of the three by:
· Reducing vehicle conflicts with pedestrians and bicyclists
· Reducing bike and vehicle speed differentials
· Reducing vehicle speed in general within and approaching the intersection
· Widening the sidewalk to increase pedestrian capacity and comfort
Widening the sidewalk will in turn enhance the coastline experience and beach activities as pedestrians
will feel more comfortable, reclaiming the area. The roundabout alternative allows for the most sidewalk
widening, although all of the proposed alternatives offer improvements to sidewalk widths. The roadway
improvements proposed with this project are being coordinated with the City of Carlsbad Beach Access
Repairs Project, in which the city is working to repair access stairways, existing sidewalks, and the seawall
located along Carlsbad Boulevard, between Pine Ave and Tamarack Ave, and Carlsbad State Beach. Note
that the proposed improvements for the Beach Access Repairs Project do not encroach into the proposed
Feb. 6, 2023 Item #4 Page 37 of 324
Final Carlsbad Boulevard and Tamarack Avenue Intersection Improvement Project Alternatives Analysis 22 of 27
project limits for the subject project. However, the improvements are directly adjacent. With these two
projects side-by-side, all modes of users can expect a safer experience during their visit to the coastline and
Tamarack Beach upon these projects’ completion.
AESTHETICS
As would be expected with new construction, the three proposed alternatives would all improve the
aesthetics of the corridor and subject intersection and introduce new landscape areas to offset proposed
flatwork. The signalized alternatives would likely implement planters within the curb extensions/bulb-outs
alongside and between each of the curb ramps. The roundabout would do the same, as well as provide a
minimum 2-ft planter strip behind the curbs within the roundabout itself. There is an opportunity to
provide further landscaping with potential for a large tree or piece of artwork within the center.
Additionally, the roundabout would provide a clearer unobstructed coastline view and maximize the public
and private vista areas with the removal of the overhead traffic signals.
Although all build alternatives provide aesthetic benefits over the No Build Alternative, the roundabout
would be the most charming and visually appealing alternative of the three, as depicted in the visual
simulations below. These simulations include views from both north and south of the subject intersection
on Carlsbad Boulevard of the proposed Signalized 3-Lane Intersection (which can be assumed to be an
equal visual representation to the Signalized 4-Lane Intersection Alternative) as well as the Roundabout
Intersection Alternative.

PROJECT ALTERNATIVES OVERALL EVALUATION
In the Mobility Analysis, the project alternatives were evaluated based on a point system associated with
the lowest projected vehicular, pedestrian, and bicycle LOS for each alternative, where LOS A represents 6
points, LOS B represents 5 points, LOS C represents 4 points, LOS D represents 3 points, LOS E represents 2
points, and LOS F represents 1 point. Additionally, queueing was evaluated by assigning points based on
the worst-case 95th percentile queues where 0-100 feet of queueing represents 6 points, 101-200 feet
represents 5 points, 201-300 feet represents 4 points, 301-400 feet represents 3 points, 401-500 feet
represents 2 points, and 501+ feet represent 1 point. Table 5 provides a comparison between each
alternative based on this system.
As shown in Table 5, the Roundabout Alternative received the best overall score (21 points) based on
vehicle, pedestrian, and bicycle LOS and queueing. In addition to providing acceptable LOS and reasonable
queueing, the Roundabout Alternative would also enhance the pedestrian and bicycle experience and
improve safety in the study area. The second runner-up was the Signalized 3-Lane Intersection Alternative
with 17 points, followed closely by the 4-lane Alternative with 16 points. Compared to the No Build
Alternative at 12 points, all three build alternatives provide significant improvements compared to the
existing condition.

Based on the parameters, the Roundabout Alternative provides the best overall score based on vehicle,
pedestrian, and bicycle LOS and queueing. In addition to providing acceptable LOS and reasonable
queueing, the Roundabout Alternative would also enhance the pedestrian and bicycle experience. By
narrowing the roadway to one through lane in each direction followed by a sharp curve into the
roundabout, vehicle speeds and pedestrian crossing distances will be significantly decreased. As discussed
in the Safety section of this report, this would reduce the number of high-speed collisions and provide the
safest scenario for all users. In addition, the roundabout also slows bicyclists’ speeds by using 5-foot-wide
bike ramps angled at 45-degrees, forcing them to slow down as they join with pedestrians within the
sidewalk. For bicyclists that choose to stay within the roadway and join with the vehicles entering the
roundabout, vehicles are slowed enough that they’ll be traveling at similar speeds.
As discussed in each of the sections of this report, the enhancements provided by the roundabout are
superior to the other alternatives in almost every category, including pedestrian and bicycle enhancements,
traffic impacts and performance, environmental constraints, safety, and aesthetics. For the one remaining
category: beach access, all three build alternatives were found to produce similar benefits by aligning with
the adjacent Beach Access Repair Project. Overall, the roundabout was the front runner in almost every
category, and overall provides the most benefits.
Displayed below in Table 6 is an overall alternatives comparison table outlining several aspects of the
proposed design alternatives as well as the No Build Alternative. This table has been assembled as a tool for
comparing many of the features offered from each alternative, although does not include every topic
considered in this report. Items shown include:
· The sidewalk width over the Agua Hedionda Lagoon bridge is provided, showing that the Signalized
3-Lane Intersection Alternative and the Roundabout Intersection Alternative provide more space
for coastline viewing from the bridge than the Signalized 4-Lane Intersection Alternative.
· The existing 5-foot sidewalk on the east side of Carlsbad Blvd to the north of Tamarack Avenue will
remain protected in place for the signalized alternatives, while it will be widened to 10 feet for the
Roundabout Intersection Alternative.
· Bike lane and buffer widths are provided—the key being that the Roundabout Intersection
Alternative provides the widest of both (generally the preferred 8-foot width with 3-foot buffer).
· All proposed alternatives add additional parking spaces over the No Build Alternative.
Feb. 6, 2023 Item #4 Page 41 of 324
Final Carlsbad Boulevard and Tamarack Avenue Intersection Improvement Project Alternatives Analysis 26 of 27
· The left-turn from Carlsbad Boulevard onto Sequoia Avenue would be closed with the two
signalized alternatives, while it would remain open in the No Build and Roundabout Intersection
Alternatives.
· As discussed in the Safety section, the roundabout produces far less conflict points between all
modes of transportation, including vehicles, bicyclists, and pedestrians. Displayed in the table is the
total conflict points between vehicles and bicyclists at the subject intersection for each alternative.
The proposed signalized alternatives introduce some new conflict points at the bus pull-outs, so
have a slightly higher count than the No Build Alternative, while the Roundabout Intersection
Alternative is less than half the number of conflict points of all other alternatives.
· As discussed in the Safety section, the signalized alternatives introduce some safety measures,
which make them safer than the No Build Alternative. However, the Roundabout Intersection
Alternative provides the highest improvement regarding safety.
· All proposed alternatives achieved LOS A for Pedestrian MMLOS, compared to LOS D for the No
Build Alternative. However, all alternatives (including the No Build Alternative) achieved LOS A for
Bicycle MMLOS.
· In the Mobility Analysis, the Roundabout Intersection Alternative achieved the highest LOS of B for
the peak-hour traffic, compared to LOS C for all other alternatives. This means traffic can be
expected to perform better with the roundabout, even at the worst hour, compared to the other
alternatives.
For the reasons outlined above and throughout this report, the design team suggests selection of the
Roundabout Alternative as the preferred alternative for this project.

Hi!
As a Carlsbad resident I am 100% opposed to roundabouts. Carlsbad Boulevard is a busy, high traffic roadway.
Leave it four lanes with traffic lights. Enough with the so-called road diets and traffic calming. These don’t calm
traffic. They make drivers angry and make the road more dangerous, not less. Please stop pandering to the spandex
bicycle crowd. They don’t seem to accept that bike lanes are for bikes and traffic lanes are for cars. If you want safer
streets, strictly enforce traffic rules against cyclists and e-bikes. They regularly run red lights and ignore stop signs.
They fail to yield to pedestrians. Large packs of them, especially on the weekends, refuse to stay in the bike lanes
where they belong. Severely crack down on cycle lawlessness and road safety will improve for everyone. Thank
you! Alan

Subject:Tamarack/Carlsbad Blvd Roundabout - Public Input for Feb 6, 2023 hearing
Date:Tuesday, January 10, 2023 11:46:45 AM
Traffic Committee:
Regarding the Carlsbad proposal for a Roundabout at the Tamarack/Carlsbad Blvd
intersection, I am against this proposal. I am submitting this email because I will not be able to attend the Feb 6th public hearing in person.
Roundabouts are a great solution in specific settings such as slowing the primarily car traffic
on neighborhood streets such as the Roundabouts on Leucadia Blvd. In fact, I wish there was one on La Costa Ave at Gibraltar. However, a Roundabout on the busy intersection of
Carlsbad Blvd/Hwy 101, with competing cyclists, pedestrians, and cars, has the potential to place all at risk.
The recently installed Roundabout on Hwy 101 in Encinitas is an example of it being scary for
cyclists because of the narrowing of the road going through the Roundabout. TheTamarack/Carlsbad Blvd intersection adds many more pedestrians to the mix, which renders
that intersection even more chaotic and dangerous.
A Roundabout at the Tamarack/Carlsbad Blvd might also have the unwanted consequence of forcing more cars onto neighboring residential streets.
Pedestrian-activated Flashing Lights are also not a good idea, especially if the flashing light is
"yellow" rather than "red." They are dangerous for 1) pedestrians who are ignored by cars that consider a "yellow" light as a suggestion to stop, and 2) for cars who stop short, triggering a
rear-end accident by the vehicle behind. An example of dangerous a dangerous flashing yellow light is on Hwy 101 in Pacific Palisades (Los Angeles).
Respectfully,
Alice Noble

This would be a huge mistake at Tamarack Ave as traffic is already congested. The roundabout would back the traffic past Cannon Rd. NO VOTE FOR ROUNDABOUT ANY WHERE!

Subject:Tamarack revision feedback
Hi Lauren, thank you so much for sending this notice of the revision plan. I live on Chinquapin Ave and have enjoyed my
time in Carlsbad way more than anywhere else I've lived in North County (Solana Beach, Cardiff, etc).
I think the roundabout is a great option, and it seems to have worked really well in Leucadia. No idea of the specific data
regarding a roundabout's ability to manage flow efficiently in/out of the beach lot, but I imagine it's better.
Since this will mean more steady traffic through that intersection, a really meaningful (and cheap) addition would be
another on‐demand crosswalk (similar to the two or three a bit north) between the Agua Hedionda Lagoon trailhead and
the stairs down to the Tamarack jetty. There's a lot of jaywalking traffic that occurs because there's not really any good
options for residents on that side of the lagoon, and the lack of a stoplight would mean there aren't as many breaks in
traffic for people to make their crossing.
Any idea of the cost of one of the crossings that was added to the north?
Thanks,
Andrew

Dear City of Carlsbad, I am a longtime resident of the city, and while I don't mind roundabouts in general, I think putting a roundabout at this location is a bad idea. At least according to your renderings, it appears that the plan would combine a roundabout (which is confusing to people), a sharrow lane (which is confusing to people), and a pedestrian crosswalk (which is confusing to people). Add to the mix visitors who aren't familiar with the setup, and kids/teenagers going to the beach who aren't known for following rules of the road. It's just too much going on for one small area, and would be an accident waiting to happen. Even in the rendering it looks like the guy in the wheelchair is about to get hit by a car. I hope you decide on a safer solution. Barbara Oetting

I am in favor of the option of a stoplight and 3‐4 lanes on Carlsbad Blvd at Tamarack: 1. Traffic on Carlsbad Blvd ,
northbound, in the 4‐6 time frame is very congested. Reducing to two lanes would result in more congestion, more
pollution as cars idle in the que to enter the proposed round about. Like it or not, Hwy 101 is the alternative route when
I5 is congested/stop/go. Two lane option would make traffic flow and entry from the neighborhood, except, at
stoplight, very difficult. 2. The two lane option would severely limit emergency vehicles (fire/police) from moving
Northbound or Southbound on 101. 3. Carlsbad needs to decline the request from Virgilicci’s to expand, as this would
increase congestion at the intersection. 3. Moving the bus stop makes sense for me. 4. Additional parking should not be
at the expense of smoother traffic flows…….Bill Blank

I think that option #2 is definitely the best choice for the people of Carlsbad. The only concern is that
it will restrict traffic of people visiting Carlsbad. One of the problems in Carlsbad is that there is not
enough parking for the beach goers that visit here from out of town.
I also believe the speed limit on Carlsbad Blvd should be 35 all the way to Island Way once the restriping of the roadway between Palomar Airport and Island Way is completed. There is too much
walking and bike riding activity in this stretch of the road to allow for a 50 mile per hour speed limit.

I think the current stop lights are much safer than a roundabout. The flashing pedestrian lights give plenty of warning
and slow traffic better than a roundabout would.
Drivers get clear signals which they will not have with a roundabout and pedestrians who jaywalk will be injured.
Carlsbad Blvd is one of the loveliest drives in the county. Don’t ruin it.

Hello,
My family (including one child under 2 and another baby one the way) uses the Tamarack beach entrance and sea wall
walking paths near the corner of Carlsbad and Tamarack frequently. The traffic circle would be a huge improvement
compared to both what is there now as well as the other option that would keep 2 lanes and the traffic light.
Safety should be a priority, and based on the information you all put together on these options, the traffic circle would
be by far the safest option for this intersection, which sees heavy bike and pedestrian traffic.
Thank you,

Hi Lauren,
Wanted to share feedback as a 35+ year Carlsbad resident that has lived this entire time within blocks of
this intersection.
I strongly advocate for possible improvements to this intersection - but Not Converting this intersection to
a Roundabout.
I am an avid biker and walker, and use this intersection every day I am not traveling - so my feedback is
valid and current.
I lived on Sequoia Ave for a decade, and understand it's shortcomings when intersection PCH. Right
turns are like any other intersection, and if I every needed to go south on PCH at rush hour, I would
simply go east to Garfield, then left and down to the intersection in question. Would add no more than
60-90 seconds to my travel, and with the left turn light at Tamarack (turning south on PCH) this method
was faster than trying to turn south off of Sequoia onto PCH, and Much safer.
I bike up into Oceanside every weekend (to the pier area), and the roundabout leaving Carlsbad is the
most dangerous part of my travel! Do you bike this roundabout every week?
Locals and tourists, both, do not know how to properly use roundabouts. I see near collisions almost
every weekend! I am not safe, and about 1 out of 4 times I go though this roundabout I almost get run
over. Most dangerous intersection in Carlsbad to me personally. I see your note about FHA safety, and
from personal experience on a regular basis, I 100% disagree!
Roundabouts in Europe probably can stand behind data like this as they know how to use these
intersections. The CB/Oceanside Roundabout is horrible for both driving and biking.
If I went down your list - here are my comments as a long time Carlsbad resident that uses this
intersection on a daily basis in multiple ways (car/bike/walk):
Traffic: Satisfactory for leave it alone is fine by me
Bike/car conflict: Who ever says a roundabout is safer is absolutely crazy, and obviously doesn't bike
from Carlsbad down to Oceanside much! This is a totally false position (suggesting the Roundabout is
safer)
Sidewalk width - no real meaningful difference between the two, and should not play into any decision as
important and impacting as this. I walk to Cannon regularly, and have no issues with the sidewalks.
Bike lane - I bike this intersection almost every weekend, and I am perfectly fine with what we have. I see
little advantage to me by changing. I think these buffers are crazy, I stay in my lane, and cars stay in
theirs.
We Must keep 2 lanes flowing both ways on PCH (4 lanes), and all roads that are 2 lane each way today
must stay that way. What they did down in Oceanside merging down to a single lane causes mile long
backups in the summer each way. BTW, the roundabout between CB and Oceanside creates a auto
traffic nightmare in the summer as well! This should be removed in my book.
Sequoia - already shared above
Car noise and pollution - Who ever thought up this one needs counseling. Hope it wasn't you ;o) I 100%
disagree with both concepts of this line item, and think it's a way to divert attention from the real issues.
Emergency access - your tables suggest no improvement. I would suggest a roundabout would slow
down Fire and emergency vehicles tremendously - as it would stall them with the roundabout, and they
can maneuver though a standard (existing) stoplight. I think this is a smart intersection already, and can
detect flashing lights on emergency vehicles and switch traffic control lights to enable emergency vehicles
easier access. Even if it does not, what we have is better than a roundabout in my book. If it's not a
smart intersection, spend our hard earned tax dollars on that type of improvement!
So as you can tell, as a Long time Carlsbad resident, that has lived within a few block of this intersection
for 35 years - I am completely against making this into a roundabout. I hope you weigh residence input to
Feb. 6, 2023 Item #4 Page 121 of 324
those that have almost 4 decades of personal experience, use the intersection daily, and have seen first
hand how horrible roundabouts completely eliminate my personal safety.
Feel free to call me if you would like to discuss my personal, long term, interaction with this intersection.

Hi Lauren,
I have been living in Carlsbad for years. I live right next to this intersection Tamarack and Carlsbad Blvd, and it is a
busy one.
Please don’t make option 2 “Roundabout” the new safety plan. This is too much for the amount of people that would
be riding bikes and crossing, no cars would get a turn to go at all. This would create a traffic nightmare, and nobody
or most people in this area do not know how to correctly or safely use roundabouts either. I have seen the bad results
of a roundabout that does not work well in Oceanside and in Encinitas in smaller areas, and additionally this is just
too large a intersection for a roundabout. I really feel this would create a bigger danger for pedestrians and bikers
because the backup of cars would cause road rage and people would accidentally get hit since there are no lights
controlling everything.
Thank you for your consideration of my opinion and understanding of my request not to use a roundabout in this
intersection in Carlsbad.
Best,

I cannot state this more strongly, that the only sensible option is NUMBER 1. It makes good sense for traffic flow and
pedestrian and bike safety.
Option Number two is simply a bad idea. I have family who live on Carlsbad Blvd and I witness almost daily the traffic on
this street. It’s very heavy at times especially during spring and summer months. The proposed idea of traffic
Roundabouts will create so much more idling traffic jams as cars wait their turn to get through the 2 lane highway at the
intersection. This traffic will increase noise and air pollution and create dangers for bikers and pedestrians because
most drivers are confused when they get to the traffic roundabouts.
Option ONE is the best solution.

through traffic. It would also be helpful to have green cross hatching on Carlsbad Blvd to remind drivers the bike
lane is not a place to stop and check out the surf, load/unload passengers and gear for their day at the beach or wait
while they pray for a parking space to miraculously appear.
The single-lane roundabout looks like a winner to me!

Hello traffic commission,
I would put my vote in for opinion #2. We need more street parking with larger area for walkers/runners. We don't
need more traffic lanes. I would use the street as a bike lane to accommodate more street parking.
Thanks,

Option 1 would be safer for all!
Option 2 concerns:
I live in Bressi Ranch ‐ we have at least 4 roundabouts in our neighborhood. Half of the residents here still don’t have a
clue how to correctly use a roundabout!
Now you’re going to expect over 3 million tourists annually to figure it out. It’s a disaster waiting to happen.

I want to encourage widening the walking path/sidewalk south of Tamarack, on the west side
of Carlsbad Blvd (ocean side of street). It is necessary to step off the sidewalk and enter thestreet/bike lane when pedestrians are passing each way on the sidewalk. There isn't enough
space for people to pass each other without entering the road.
Adding street parking around Tamarack might help out the neighbors because we park in frontof their homes in the blocks around Tamarack. HOWEVER, adding street parking would
mean more cars entering and leaving lanes of traffic, and potentially more unsafe conditionsfor cyclists and pedestrians. I would rather see the beach parking lot expanded than add more
parking chaos on the street.
Thank you.Christine Habib

Subject:proposed changes to the 101
Dear traffic and city council,
I'm writing about the proposed changes to the 101. It seems Carlsbad is bent on going down the same road that my city,
Encinitas, has with Streetscape. Residents, businesses and cyclists are not happy with the results of Streetscape so far.
Its cost has far exceeded its estimates and at $65M, has created debt and taken funding from more important basic
infrastructure projects, specifically flooding in the same area.
Why are coastal cities that are determined to densify, removing lanes and ultimately creating more pollution (via more
traffic) by creating lane reductions? I'd hate to see Carlsbad's beautiful coast destroyed by expensive, popular plans that
have not served other cities well and will only create division between residents and more division with its government.
Though change is inevitable, it's incumbent on city leadership to plan judiciously and wisely for growth by
improving infrastructure and planning for more traffic and better traffic flow, as well as creating enough parking for
businesses, residents and visitors, which is the lifeblood of all of our communities.
Kind regards,
Cindy Cremona

Dear Lauren,I looked at the plans projected for the intersection at Carlsbad blvd
and Tamarack Avenue. I definitely and strongly urge the City to useOption 1 for two reasons.
1) Traffic signal keeps traffic moving. Roundabouts are so outdated andpeople don't know how to use them. We will have traffic nightmares
which is a costly way to get drivers frustrated!2) The Freeway, El Camino Real, and Carlsbad Blvd. are the only means
of north- South traffic if the freeway is backed up( which it doesseveral times daily). or there is an accident.
A roundabout would only contribute to the congestion. I am sure therewill be buildings built where the power plant is somewhere in the near
future and there will be a considerable traffic increase in this area. Aroundabout would only contribute to the congestion.
I am for option 1 and totally against option 2 and any further use ofroundabouts in Carlsbad.

I generally like roundabouts.
This one proposed , I vehemently object to.
Why?
- Reducing 2 lanes to 1 assures gridlock regardless of the roundabout - more pollution and increased global
warming
- The design you used at the Oceanside border is poor (not my original choice of words) - the bike lanes
disappears into the car lane at the roundabout ...so I can choose to stop (going uphill South ...p*** poor) , merge in
front of cars (die) , or ride up the sidewalk.
Why not ask the various (real) bicycle clubs (Swami's , SDBC, CycloVets , CAF) who ride there every day ( notice I
left out the lobby group ).

Dear Commissioners:Thank you for your efforts to improve safety and traffic flow at the intersection of Tamarack
Avenue and Carlsbad Boulevard.I support Option 1. Although I generally support roundabouts, this intersection presents an
unusual challenge to such an installation -- namely, that drivers exiting the State Beach parking lot are below the grade level of Carlsbad Boulevard. Entering a traffic circle from this
approach would be difficult and hazardous. This challenge would be even greater for the many out-of-town visitors who use the beach parking lot but are unfamiliar with our streets and
traffic.As a frequent user of this parking lot, I would feel safer and more comfortable with a red or
green light -- that is, knowing for sure whether I should stop or proceed through the intersection. I encourage you to adopt Option 1 for improved signaling and lane use.
Thank you for considering my input.Sincerely,

are no non-business residents as close to the street level as our residence at 111 TamarackAve. We are in favor of Option 2, the roundabout design.
Here's why:
1. It will slow speeds through the intersection.
2. It will reduce noise levels from motorcycles revving their bike to accelerate3. It will be MUCH safer for pedestrian crossings.
4. The traffic enforcement outside our North facing window will be minimized5. It will minimize car club and motorcycle cruising this stretch.
6. It will minimize the 5 traffic detours when traffic builds on the 5.
We are excited about the proposed option and look forward to the completion for this project

HI, I’m sending my thoughts about the proposed changes for this intersection. I believe the safest and most effective
option is to keep the traffic signals. I base this on my experience driving/walking in an area that has many roundabouts ‐
Vail, Co. I spend a number of months each year in Vail and it too is a tourist area and has become a year round resort
community. The roundabouts here work well in areas where you’re mostly dealing with cars and buses. They do not
work well when you consistently have people on foot or riding bicycles. The roundabouts become very dangerous
under these circumstances and end up being much less effective than having a signal control the movement of vehicles
and walkers/cyclists.
The roundabout in the north part of Carlsbad (leading into Oceanside) works well because there aren’t many walkers in
that area and most of the bicyclists are headed north/south. This isn’t the case at the Tamarack/Carlsbad Blvd
intersection. it often feels like there are as many people walking/cycling at this intersection as there are vehicles.
I appreciate the opportunity to provide input.

Hi Lauren,
I am responding to the brochure we received recently regarding potential changes on Carlsbad Blvd. at theTamarack intersection. Having lived on Garfield Street for a long time, both my husband and I have come up withsome creative solutions to the current alternatives being offered to ease traffic flow, increase pedestrian safety,provide access to the coast and all of its wonderful beaches, and support the property owners who deal with uniquechallenges living along the coast.
1. Rather than construct a round-about, please keep the two lanes and the light at Tamarack and Carlsbad
Blvd. This light allows pedestrians to cross safely, allows ample flow on either side of the meridian/center
line and keeps the flow of the coast going.
2. Blocking off Sequoia St and turning it into a cul-de-sac would result in a safer way to enter the
neighborhood. There is always an inordinate amount of traffic cutting through and making a left turn onto
Garfield Street without looking left due to a large tree and a Stop sign that obstructs vision to the driver.
It is dangerous for pedestrians as well who are walking on Garfield Street.
3. By maintaining just one access into the neighborhood with the stop light at Tamarack the side streets will
be safer without access from the coast through Sequoia. People must cross at the corner on Tamarack or
make a right turn here, or continue down the coast. A roundabout is not a good solution for this
intersection. We definitely need the two lanes going north and south on Carlsbad Blvd.
4. By keeping the light at Tamarack, and not turning onto Sequoia, the bus stop can be enlarged for safety,
the bike lane would continue without interruption, pedestrians would not have to cross another street; thus
eliminating another conflict point.
5. The neighbors who live on Sequoia would have easier and safer egress and ingress into their own
driveway.
6. Tamarack is a busy intersection and we need to keep everyone safe...we love that the police position
themselves at the north end of Agua Hedionda lagoon and watch for speeders.....we need to keep that
stretch at 35 mph or slower....
7. Without access into Sequoia Street, bike riders would not have to check for traffic at the turn as there
would be no turn...the bike lane would not be interrupted and everyone would be safer.
Please consider these alternatives to the plan that was presented for these changes to Tamarack Ave. and Carlsbad
Blvd.

I would be concerned about the traffic coming up from the beach parking lot, traffic coming up the hill has limited
visibility
"roundabout at Cannon Road and Carlsbad Boulevard."
Isn't a new fire station going in on Canon road (old SDGE) just a block from Carlsbad Boulevard blvd? Fire engines don't
navigate well over roundabout.
My opinion on roundabouts:
They are ok for low volume of traffic like State St.
But for heavy flow it becomes more of a race for drivers to get into roundabout.

Lauren,
I wanted to provide some feedback on the proposed redesign of the Tamarack/Carlsbad intersection. We live at
Tamarack, on the southeast corner of that intersection. We are strong advocates of Option 2 “Roundabout”.
Traffic is frequently backed up in front of our place from the signal. We’ve seen many places locally and around the
states where roundabouts provide much less congestion. For us and other residents this will also mean much less
pollution from the standing vehicles.
There are many vehicles every day traveling north on Carlsbad Blvd that pull an illegal u-turn (or many times a 3-
point turn) trying to access the beach to the south. Having a roundabout in place would eliminate that traffic hazard
and make it easy for beach goers to access the southern beach.
Thank you for considering the communities input. If we can provide any additional perspectives, fee free to reach
out.

I see the email that was sent out with the traffic signal or roundabout options. As a 18 year Carlsbad resident, I see alot
of issues in putting a roundabout in at this very busy intersection. The traffic signal is a much better and safer option on
my opinion. The traffic light is there currently based on high traffic volume. If a roundabout is put in, I believe it would
create more traffic, more accidents, and pedestrians causing traffic as well. Hopefully the current traffic signal stays in
place to keep the road safer.

Dear Lauren Ferrell,
We have owned our beach house for over 16 years on l52 Chinquapin and very familiar with that intersection. We use
the crosswalk several times a week.
I love, love, love roundabouts; however, the’re way too many pedestrians using that intersection to be safe for either
pedestrians or vehicles. Roundabouts are new to California which means that people are unfamiliar with the right of
way rules for them and may cause a lot of accidents.
We live in Henderson, Nevada and have many roundabouts in Lake Las Vegas and the city of Henderson. Very few
pedestrians cross our roundabouts. The reason roundabouts are good is because it keeps the traffic flowing; but if there
pedestrians crossing its going to cause a lot of rear end traffic accidents or a pedestrian accidents. Plus the driver
entering into the roundabout will need all the concentration to exit the desired lane.
Our suggestion would to leave the Signals. DO NOT DO ROUNDABOUTS !

Hello Lauren,
Living in the immediate vicinity of this project gives me a point of view I hope will bereviewed. We navigate this proposed intersection daily and have an alternative idea. I will
comment on the proposed plans then offer my suggestion.
Option 1:Sequoia Ave is the main problem:
* street parking has no order and many times passageway is reduced to a very narrow 1 laneroad
* Vehicles traveling eastbound from Carlsbad Blvd and then turning left on Garfield St.encounter a blind corner from the NW corner. Near accidents are a daily event here and with a
reduced traffic flow at Carlsbad Ave & Tamarack Ave, the Sequoia Ave traffic will increasesubstantially as vehicle attempt to shortcut that intersection
Option 2:
* reducing Carlsbad Ave from 4 lanes to two will create an immediate traffic jam * with no traffic light, frustrated drivers will be meeting other vehicles, cyclist, and
pedestrians at 1 narrow conflict point * southbound left turn into the beach parking from the roundabout during high season
creates another conflict point * Sequoia Ave problem (see option 1 comments). Substantial traffic increase at the Garfield
intersection creates an additional traffic burden on the Garfield residents. * westbound exit from Sequoia Ave will be nearly impossible
Suggestion for consideration:
* Option 1 best serves the flow of traffic and adding a second crosswalk is a great idea * Close off the ingress / egress flow to Sequoia from Carlsbad Ave making Sequoia a cul-
de-sac. (think Manzano Dr & Carlsbad Blvd). The inconvenience to Garfield St, ChinquapinAve, Date Ave, and Palm Ave residents will be minimal, create a safer access point for
pedestrians accessing the beach, and undoubtedly be a safer traffic solution for the SequoiaAve and Garfield St residents.
Thank you for your consideration.
Best,
Gary Cruse

driven through them in Carsbad, Leucadia, an La Jolla. ALL OF THEM are some of the WORST ideas anyone could ever

such a busy intersection from all four directions. IF you go through with this terrible idea, I shudder to think of the

Subject:Carlsbad Blvd and Tamarack Ave Proposal
Date:Tuesday, January 10, 2023 11:38:04 AM
As an impacted resident, below is my input on the two options proposed:
Option 1 - Traffic Signal
As a resident of Sequoia, the restricted access makes it much more difficult to leave and or come home. I exit
frequently southbound onto Carlsbad Blvd, as well as return from the village via left turn southbound on Carlsbad
Blvd. Travel will require more time and gas, and lower the value of my property with limited access.
I don’t see an explanation of where the additional width for the bus insets and expansion of the Carlsbad Blvd
sidewalk will come from?
Your table say this option will reduce car & noise emissions. I cannot see why that would occur - please explain.
Option 2 - Roundabout
This is clearly my least preferred option. We use the pedestrian crossing daily going across both Tamarack and
Carlsbad Blvd. This option presents significant opportunity for car vs pedestrian situations. Californians are not
experienced with roundabouts and the area is highly trafficked by younger drivers who frequently speed. The safety
of pedestrians and the exposure to liability by the city is significant. At nighttime, both in the summer with tourists
and in the fall with less daylight, visibility of pedestrians will be limited.
It is very common for Carlsbad Blvd to become a version of the old Carlsbad Raceway after 8:00pm each night,
with cars easily reaching speeds of 80-90+ mph. Pedestrians will be unsafe in the crosswalks as will cars trying to
enter/exit the roundabouts.
The roundabouts also appear to feature single lanes as they approach and exit. This will become a huge bottleneck
during the summertime and each week night from 4:00pm - 6:00pm with commuter traffic. This will significantly
add to traffic, car noise, and emissions in the area—and not present the “best” option as your table depicts. Cars
trying to navigate the roundabouts will be suddenly reduced from two lanes to one and then have to wait on
pedestrian traffic. It will become an even worse traffic nightmare. This will not be “efficient” for future traffic flow
as your table denotes.
Again, not sure where the width is coming from on Carlsbad Blvd for the bus inlets and the expanded width of the
sidewalks.
Thanks for the opportunity to comment.

As a Carlsbad resident who lives just off of Tamarack Avenue, I strongly support the construction of a single-
lane, modern roundabout for the intersection of Carlsbad Blvd and Tamarack Ave. The additional space that it
provides for pedestrians and cyclists will lead to less accidents and safer experiences for residents and visitors.
Thank you,

Subject:RE: Input for Tamarack and Carlsbad Blvd Roudabout
Hi Traffic & Mobility Commission ‐
My husband and I live off Chinquapin, about two blocks from where the proposed roundabout would be. I think the
roundabout is a great idea. I am always very nervous crossing the street at that intersection, particularly because cars
will turn right directly off Carlsbad Blvd onto Tamarack on my footpath even when it's my turn with the crossing light.
They just don't pay attention. It's particularly dangerous at night, and I've almost been hit a couple of times. Or they will
be coming towards the water down Tamarack and turn right in my footpath even when it's not their turn at the light. It's
especially dangerous crossing on the other side of the road too, the side where the ocean is, because the bus stop is
right there and there's no real crosswalk. Please let me know who I can send support letters to so I can continue to show
my support for this project as a local resident.
Thank you very much,
Havilah

Subject:Carlsbad Blvd & Tamarack Ave improvements
Hi. I’d like to give you my feedback on the proposed improvements to the Carlsbad Blvd & Tamarack Ave intersection
improvements.
I like the idea of the roundabout, but I am a little concerned about the amount of foot traffic at the intersection. Lots of
people (including myself cross Carlsbad Blvd there and there is lots of traffic. One lane should help though.
My other comments:
1. I do think that the sidewalk needs to be widened over the parking lot/bridge. It’s not wide enough for two people to
walk side by side. It’s especially difficult when someone has a stroller.
2. If walking on the West side of Carlsbad Blvd at the entrance to the parking lot there is no crosswalk or signals for
pedestrians, which makes it difficult to figure out when to walk. It looks like that may be addressed in the renderings, so
I hope that gets taken care of.
Thank you,
Janelle Dodkin

I own a unit at 111 Tamarack Ave, Carlsbad, CA 92008 and was very happy to see the
redesign ideas. My husband and I are all for option 2 - roundabout.
The noise from the cars speeding during the day and especially at night is extremely loud andoften scares us. It’s even worse when the cars and motorcycles wait at the light and rev their
engines.
From our balcony we have seen so many fights between bike riders and motorists. We alsoseen a lot of close accidents between them.
Crossing that intersection to get to the beach is quiet a nightmare especially for the people
crossing with children and their beach gear.
The last concern is when cars are exiting the beach parking lot, not everyone looks both waysbefore turning right on red. It’s dangerous.
Thank you for working on this project and for asking for out input. I hope you consider the
roundabout for safety and efficient traffic flow.

Hello,
I reviewed the renderings and descriptions for options 1 and 2. I favor option 2 but have the
following comments/concerns:
1. The bike lane gets weird through the traffic circle. I don’t understand how bikes safely
navigate the circle without totally hindering vehicles. Would one stupid bike rider cause the
entire circle to come to a stop?
2. There should be some sort of evidence regarding the effectiveness of the traffic circle for its
size and expected traffic volume. Show data that proves it is better throughput than option 1,
across many traffic volumes (light, medium, heavy).
3. Show predicted impact of large trucks going through the circle. Will there be limits on vehicle
size which can safely navigate the circle with bikes and pedestrians?
4. Show that you have considered kids on e-bikes. There are so many and they are not always
skilled riders – but they go fast as if they were motorcycles.
This circle will be much more crowded than the one near the North end of Carlsbad so I don’t think
that can be used as evidence for how well this new one will work.
Thanks for your consideration. Best regards,
Jeff Schafer

Hello,
I wanted to provide my SUPPORT for the tamarack avenue roundabout. We have an
increasing number of bicyclists and we need to calm traffic on Carlsbad Avenue.
My suggestion for improving it would be to create separated bike lanes where a curb creates a buffer between cyclists and cars. We have too many young teenagers and adults getting hit
riding bikes and ebikes and we need dedicated bike lanes on the coast and on arteries that access the coasts.
Overall I support this project as it but feel it could be enhanced by creating a dedicated bike
lane.
Leaving the intersection as a light is a recipe for disaster.

Subject:Carlsbad Boulevard and Tamarack Avenue redevelopment community input
Date:Wednesday, January 4, 2023 7:11:34 PM
Dear Ms. Ferrell,
Yesterday, we received the City of Carlsbad mailer inviting public input on the improvements being
considered for the intersection of Carlsbad Boulevard and Tamarack Avenue. We were disappointed to
see the revival of what we viewed as an ill-considered proposal to convert this intersection into a
roundabout. Contrary to the north end of Carlsbad, where the roundabout connecting State Street to
Carlsbad Boulevard works well, this intersection is much more complex, including the entrance to
Tamarack State Beach, and has a high volume of pedestrian traffic for both the beach and sea wall
promenade. Further, the high volume of north/south Carlsbad Boulevard bike traffic is already
problematic at this intersection. Often the bike traffic (particularly the larger bike groups), do not obey the
traffic lights as they should, running red lights, failing to yield, and otherwise endangering pedestrian
traffic. We fully support greater police enforcement for this issue; however, we also see that the share the
road and yield-to-pedestrian aspect of the roundabout proposal will only serve to exacerbate an already
widely recognized problem. We fully supported the earlier proposal of dropping the number of vehicle
lanes down to three and other measures of slowing traffic, but the conversion of this complex mixed-use
intersection into a roundabout will create a pinch point that will adversely affect neighboring streets,
including our own, as well as endangering all non-vehicle users as traffic backs up and tempers flare.
We have lived in this area of Carlsbad for over 12 years, and have been watching this project closely.
Each proposal cites studies from various sources i.e. "according to the Federal Highway Administration,"
however, not only is this assertion devoid of context, I have not seen any study of this particular
intersection which takes into consideration the high volume of pedestrian traffic (particularly non resident
tourists during summer) and the impact on efficiency and safety of the proposed all-segment-yield
pedestrian crossing. The conclusion that I believe the previous study had regarding this intersection, was
that a roundabout was not feasible. We would be interested in understanding how this revived
proposal addresses those previously identified deficiencies. Having resided in London for several years,
we are very familiar with what a high-functioning roundabout can accomplish. That being said, in London,
where there is a high amount of pedestrian cross-traffic, either there are stop signals incorporated into the
roundabout, or pedestrian traffic is entirely diverted into underground passages, neither of which have
been considered in the proposed design concept. Further, unlike previous proposals of the
redevelopment, the inclusion of southbound traffic exiting from Sequoia implies that the southern lagoon
pedestrian crossing has been eliminated from this design concept, a development we find unfortunate. I
do not know if you were on this project when previous public comment was solicited, but I invite you to
review the survey conducted at that time and read it for impartiality. We participated in that survey when it
was posted, and believe it could serve as a prime example in a master class on obvious survey bias.
Lastly, we were disappointed that the option to reduce the coast highway by one lane to improve both the
promenade and increase beach access parking along the entire corridor south to Cannon seems to have
been dropped from consideration. In light of future redevelopment opportunities hopefully provided by use
of the property previously occupied by the power station, this seems like an opportunity missed to expand
the beautiful beach access Carlsbad already provides.
Thank you in advance for your consideration of my feedback, and for making yourself available to
residents.
Sincerely,
Jens Peter Timm and Melaine Timm Owners

To the City of Carlsbad Traffic Commission:
I strongly support the roundabout option of the traffic designs that you're considering at the
intersection of Tamarack and 101.
I'm a Solana Beach resident who enjoys driving to Carlsbad, then walking on the beach, dining, and shopping with friends. The roundabout option is a safe, efficient design for
pedestrians, motorists, and bicyclists. It will effectively slow down car traffic so that all who move through the intersection can do so safely and confidently. As a member of
BikeWalkSolana, an advisory group to the City of Solana Beach City Council, I'm also a strong advocate for traffic calming through roundabouts whenever possible.
I am sure that you on the Traffic Commission are aware of the many benefits of roundabouts.
Please be sure that you emphasize their benefits to Carlsbad residents once you select the roundabout design...so you don't have a public relations disaster with people who oppose them
at all costs. In 2018 the City of Solana Beach was forced to eliminate roundabouts from the design of the Lomas Santa Fe Corridor Improvement Project due to an outcry from a small
group (ROAR: Residents Opposed to All Roundabouts).
Roundabouts: YES!!!

Subject:Comment on Single-Lane Roundabout Proposal for Carlsbad Boulevard and Tamarack Avenue
To: City of Carlsbad Traffic Commissioners,
Ref: Single-Lane Roundabout option: Carlsbad Boulevard and Tamarack Avenue
A single lane roundabout will be an extremely dangerous choice.
With NO signal control over pedestrian traffic, during most daylight hours and on weekends, North and Southbound traffic will be at a crawl and backed up as a constant uncontrolled flow of pedestrians cross the intersection.
Cars entering the roundabout from Tamarack Ave or from the beach parking lot will certainly not have a fair, controlled, opportunity to enter the circle.
This option will surely cause motorists to bypass the roundabout by taking a Sequoia-to-Garfield or Redwood-to-Garfield route to bypass the roundabout during most traffic hours. This will cause additional traffic and pedestrian danger.
The CLSBVD-State St. roundabout works fairly well, but it has very little pedestrian and cross-traffic and is basically a merging intersection with a roundabout option (as I assume you are all aware).
Thanks for letting me voice an opinion! Cheers, Jim Hawes

I absolutely do not believe a roundabout will be safer at Tamarack and Canon. I think in very few situations, where you
have one lane roads, this form of traffic control works.
I have traveled and driven in many parts of the world and believe roundabouts work best in single lane applications.
When we see the assortment of vehicles from bikes, scooters, 18 wheelers, RV’s, tour buses etc……. and we try to
compress this into a one lane roundabout it is ridiculous.
I’ve lived in the neighborhood over 40 years and this is not a solution or improvement.

To whom it may concern,
In general, I am in favor of converting the intersection to a roundabout. However, I do not support the version in the
render, because it forces bicyclists and cars to merge. This is a very bad design. Bicycles need their own infrastructure.
And with ebikes becoming more and more common, and with their potential to replace cars as primary transport, we
should take bicycle infrastructure more seriously. The following video is an example of proper
design. https://youtu.be/FR5l48_h5Eo
I would like to further add that the parking and bike lane arrangement along the southbound stretch of coast highway
needs to be changed to protected bike lanes. In the current design, motorists park in the bike lanes while they wait for a
space to open up, forcing bicyclists either into the traffic lane, or between cars, both of which are hazards to bicyclists.
Here is a video on protected bike lanes. https://youtu.be/XN‐tSpQZmYk. And a design manual can be seen
here. https://www.nycstreetdesign.info/geometry/protected‐bike‐lane
Coast highway is a treasure of Carlsbad that people love to walk, jog, bike, or drive. We should make it the best it can be
for all.

For Traffic Commission meeting please add to package
On behalf of BikeWalk Carlsbad I’m writing in support of option 2 for a roundabout at the Tamarack
intersection of Carlsbad Blvd.
Roundabouts are 90% safer than signalized intersections for all users.
The roundabout allows for all traffic to keep moving and although speeds are slower and therefore
safer, the throughput for all traffic is the same or better as it can keep moving without waiting for
signals and being backed up at lights.
Crossing for all pedestrians is safer as motorists are moving slower with more attention and not
blowing through lights.
Pedestrians, runners, dog walkers will greatly benefit from the wider sidewalks and there will be less
overflow into the street to pass.
The roundabout at State street and Carlsbad Blvd was a huge improvement for bike and pedestrian
safety.
There has been push back on roundabouts with users being unfamiliar with them, but after they go
in the communities are extremely happy with the results. La Jolla is a great example of this. We
hope Carlsbad will continue the use of roundabouts to keep traffic moving safely through the
corridor.

Subject:Options for Tamarack at Carlsbad Blvd
Hi
I disagree with the option to put a roundabout at Carlsbad Blvd and Tamarack
It is too busy of an intersection, this will not make this junction safer, it will make a bottleneck and
changing this down
to one lane will increase traffic and frustrations.
People do not know how to drive around the roundabout at Buena Vista Lagoon entering
Carlsbad.
Drivers and People trying to cross the road and cyclists will all be impacted negatively.
I drive this road daily to and from work, there are so many speeders, there will be more accidents.
We need speed bumps all the way down from CVD to Cannon. Every morning going and coming
home from work
I have someone on my tail aggressively, I move over and they bomb down the road well over
45mph...
People are going to get frustrated and drive around the roundabout whether it is safe or not.
we will have long lines of traffic.... it is bad now.... what about emergency vehicles, how are they
going to get
through when it is backed up. What about summer traffic with RVs and out of state drivers
unfamiliar with the area.
Cyclists if you make the lane wider, they will only cycle 3 or 4 abreast and make safety an issue.
On the cyclist lanes now they ride 2 abreast instead of one; someone is always riding on or over
the white line... making it difficult
to drive past and most of the time there are always cars in the other lane, so hard to just move
over.
I also disagree on a roundabout at Carlsbad Blvd and Cannon..... A lot of the traffic is North and
South, people trying to
turn south or north from Cannon will not be able to get on the roundabout to do so.
Problem with Carlsbad blvd:
Speeders and drivers that do not stop at the flashing pedestrian lights/walkway, I have seen
people have close calls. I myself have almost been hit on two occasions, from drivers not
adhering to the flashing lights.

I really think we need lights in the ground at all the pedestrian cross walks. Actual lights that light up, twinkle
across the asphalt. May cities have them and we need them. I really can’t believe we don’t have them.
Good luck.

Lauren,
Thanks so much for calling me back!
There is a lot of discussion on Sequoia about this proposal and has been for years. We are
collectively concerned, and Sequoia Ave itself is a narrow cut-off street that has had its own issues
especially in the summer. One of the residents (who has since passed away) had been trying hard
for years to make it a one-way street going west-only.
I also have many other folks in the neighborhood that we can round up. My wife, Stacy (cc’ed), and I
are happy to help. We know many of the residents on Chinquapin and some of the other streets
near the lagoon as well. Can we set up a time to speak or meet next week? Please send me some
options that work for you and we can go from there. Afternoons generally better for me, but let me
know.
Regards,
Justin

Lauren,
I received the Tamarack Ave flyer from a neighbor today, and hopefully ours will arrive soon as well.I would like to see the traffic estimates on Sequoia Avenue with the plans and the Garfield/Tamarackintersection. I’d also like to see the other engineering traffic flow reports around the roundaboutduring peak season (summer) with pedestrians able to cross at will. I would like to see theassumptions in these models as well - ie - do they expect fewer vehicles to pass these roads versus theexisting 101 for some reason?
I’d also like you to review my email sent to you previously below. I will reiterate that the 101Oceanside border roundabout can not seem to be navigated competently by motorists when I passthough it, so I would expect this proposed roundabout to fail more severely with more traffic volume. Furthermore, there is no discussion or proposals about cut-off traffic on Sequoia Ave, which I wouldexpect to get worse as a percentage of vehicles passing it with either of these proposals.
I’d be pleased to sit down and discuss, which I requested in the previous email. I also asked abouttraffic impact studies, but those have not been provided either. I expect I will be very active duringthis process for Carlsbad. If it would be more productive to assemble others who live on SequoiaAvenue and the area affected by these proposals in the area south of Tamarack off Garfield Avenue, Ican begin that process as well, so please let me know the best or preferred way to move forward.

Subject: Tamarack/Carlsbad Blvd
Lauren,
Hi, I found you on the City of Carlsbad website associated with the Tamarack/Carlsbad
Blvd planning after looking over the Palomar/101 plan. I previously communicated with
Lolly Sangster. My family and I live on Sequoia Avenue and I work off Avenida Encinas
(address below), so my commute to work is rather short but entirely encompasses the
Tamarack plan and I experience navigating this area very frequently obviously. I have a
lot of concerns as the Carlsbad village traffic flow changes over the last few years have
seemed to create more traffic than less (double cross walks at Carlsbad Village and
Grand; and the undersized roundabouts that Americans continue to struggle with at the
101/Oceanside border) – I’d love to know if the city views these as successes. As a
Feb. 6, 2023 Item #4 Page 195 of 324
resident, I vote “not”.
This is very important to me given our proximity of our home on Sequoia Avenue and
daily use of these streets. From what I learned from Lolly, pedestrian safety had been
placed ahead of all other considerations; though I have no knowledge of any “ safety
events” that would suggest pedestrians are unsafe. Are there events or evidence of
unsafe outcomes?
Given the plan as proposed, I would expect a much more substantial back up in traffic
at the four-way stop at the Garfield/Tamarack intersection. All of the residents of the
area in our neighborhood (residing south of Tamarack Ave; east of 101; and west of the
railroad tracks) must now funnel through that intersection as opposed to being able to
take a left from Sequoia to travel south on the 101. I am not one to trust others’ work,
so I’d like to know if there are traffic impact studies during peak rush hours at the
Garfield/Tamarack intersection? The left from Sequoia Avenue to travel south on the
101 is used frequently by area residents. It offers a surprisingly easy, short wait to
execute; and this plan will divert that traffic towards that intersection.
One of the previous proposals considered turning the 101 between the Agua H. bridge
and Cannon to be one lane. How can this plan be considered independently of the
Cannon/101 roundabout proposal that is in the works along with other items that are
being considered? Substantial traffic backups already exist along the 101-south from
Tamarack Ave to Cannon due to the merger near Cannon. This further demonstrates the
traffic back up problem created by merging traffic on such a high flow road.
Lolly had indicated is this plan is somewhat less-than-ideal, but being considered to avoid
the longer review time from the coastal commission – is that the case? Why not wait
until the “better” or “perfect” plan can be approved and executed, rather than spend $2-
3 million on a short-term idea that seems to have challenges?
My street (Sequoia Avenue) is already a major “cut-off” street to avoid the Tamarack
Avenue right to proceed east from the 101. Cut off traffic flows through at high speeds
in their rush-hour aggravation often. What can be done to stop or alleviate this?
(humps; or a not-cut-off regulation such as Encinitas has off the 101 on the west side
during rush hour?).
I would like to speak with you at some point soon when convenient to understand the
process and how to be involved with the city’s process in general. If Sequoia turns into a
one-way street that only travels east, it will likely turn the street into a bumper-to-
bumper highway during periods of the day.

Justin Ferayorni

At a glance
The City of Carlsbad is committed to creating roads that are safe and accessible,
while balancing the needs of drivers, bicyclists, walkers and other road users.
Several years ago, the city worked with project neighbors and the community to get their input on potential designs. Since that time, the city completed additional
technical work and is now ready to get the community's input before moving on to the next phase.
Input can be shared with the Traffic & Mobility Commission in person on Feb. 6 or email to traffic@carlsbadca.gov
This project was started before the city’s local traffic emergency, but its goals support the Safer Streets Together initiative.
Public input
New designs for the intersection of Carlsbad Boulevard and Tamarack Avenue are ready
for review. Both options will address three important changes:
Widening the walking path over the bridge just south of Tamarack Avenue
Relocating the bus stop
Adding street parking
The options differ in how they manage traffic flowing through the intersection. These options include:
A three or four-lane road with a traffic signal
A single lane modern roundabout

Dear Traffic & Mobilitiy Commissioners,
As a resident of Carlsbad, I would like to provide input on these options, but am unable to attend the meeting. I far prefer Option #2. It optimizes use of the public thoroughfare for all modalities of transportation, not just vehicles. It fits the changes happening in Encinitas where highly trafficked areas are slowed down, cars are limited and space is provided for walkers and cyclists.
Vehicles on Carlsbad Boulevard already need to slow or stop for light and pedestrian crossing. A traffic circle would allow for continuous movement of all modes. Every year there are more and more examples of cities reworking their streets to better accommodate bikes and pedestrians. It is the future, and option #2 brings this future to Carlsbad.
Sincerely,
KathyDodson

I looked at the renderings for Tamarack in Carlsbad. I ride my bike through this intersection a lot. There is a lot of traffic
through this area and a roundabout would cause a tremendous amount of congestion and backlog/backup through this
intersection. And, it looks like a safety issue for bicycles. It forces bikes into the traffic lanes and forces a conflict with
cars turning right onto Tamarack. There should be a dedicated right turn lane onto Tamarack from northbound traffic.
This is where I see the most backups and conflict with bikes. This is partially caused by the first stop sign on east bound
Tamarack. Cars will back up from the stop sign all the way into the intersection. I have been hit by a car due to this
backup situation. A car trying to turn right but being backed up by other cars delayed by the stop sign. The stop sign
should be removed east bound to allow cars to get through and away from the busier intersection at Coast hwy. Extend
the bus lane into a dedicated right turn lane. Also a lot cheaper and less disruptive than a roundabout.
Thanks for listening and I hope you consider my concerns.

Traffic & Mobility Commissioners and staff -I would like to express my support for planned improvements to the Carlsbad Blvd and Tamarack intersection. Looking at the proposed options, the roundabout option has many more safety advantages not to mention less environmental impacts since it reduces vehicle idling.
The roundabout further north at Carlsbad Blvd (Coast Hwy 101) and State St years ago was a huge improvement and transformed a very dangerous intersection into a much safer environment and a more aesthetically pleasing entranceway into Carlsbad. It was a game changer for bicycle safety that is for sure.
Building on this first roundabout on Coast Hwy, another planned at Cannon and this proposed option at Tamarack is a great path forward for the City of Carlsbad.
As you likely know, the City of Encinitas will be constructing several roundabouts as part of Leucadia Streetscape along Coast Hwy to the south. Transforming this corridor from a car eccentric focus to a more complete street addressing all road users, including bicyclists and pedestrians, will further bring the areas back to the community to create a more thriving + active space along the coast. Traffic calming is an important feature of the roundabout option.
As a driver, bicyclist, and pedestrian that frequents this project area, I wanted to express my support for the roundabout option.
Thank you for your continued efforts as you serve your community (and greater North County) on this Commission.

Subject:Tamarack in Carlsbad Boulevard intersection
Hello, I am a Carlsbad resident and I’ve lived in this beautiful city since 1999. I’ve reviewed the conceptual designs for
this intersection, and do not think a roundabout is appropriate because it will likely create additional pedestrian and
vehicle conflicts since the traffic will never actually stop. Typical pedestrians at this intersection include people walking
their dogs and mothers pushing their babies in strollers or watching their toddlers ride scooters or bikes. Cyclists can
approximate vehicle speeds at a roundabout, but these other pedestrian groups are unable to match the speeds vehicles
would approach and pass through a roundabout. This would create a dangerous situation and would not improve public
safety.
In general, I like roundabouts because they keep traffic slowing but in this case where there is significant non‐vehicular
traffic in the way of pedestrians and cyclists I cannot support a roundabout, at this particular location. The idea of
widening the bridge over the lagoon entrance is good because it’s very tight for pedestrians to pass one another on the
west side of the roadway.
I walk the Carlsbad seawall weekly and in all seasons and see a lot of downsides with a roundabout at Tamarack and
Carlsbad Boulevard. I think the one at State Street works pretty well probably because there are not nearly as many
pedestrians using this stretch of roadway.
Thank you for the opportunity to review and provide comments on these preliminary designs.

I see two problems with the roundabout design. 1. It creates a vehicle choke point taking
the roadway from 2 lanes to 1 in order to negotiate the roundabout. 2. It mixes bicycles that
don’t want to use the roundabout with pedestrian traffic together on the sidewalk I’ve lived
in the U.K. and am very familiar with roundabouts and their benefits with keeping traffic
flowing. That only occurs when the lanes are not diminished for the roundabout. Crossing
the intersection at Pine to access the beach I am all to familiar with having to be heads up
for the vehicles and numerous bicyclists who run that light. I can’t imagine having to
navigate a sidewalk safely with the same bicyclists.

I’m excited that the city will be improving this very busy area. I live at Tamarack and Garfield. I walk/drive/bicycle

I love the ideas presented with the traffic circle and wider sidewalks. However, based on the circle at PCH near the
Oceanside border, I’m wondering if it won’t be frustrating for pedestrians and motorists? The circle at the Buena
Vista Lagoon is great because there is very little foot traffic and the cars flow nicely. Tamarack might do better with
an intersection like what is at the Village — all cars or all pedestrians with an ‘X’ crossing for foot traffic.
Thank you for your efforts to include citizens in this process. I’m sure it’s going to be a big job.

The area is pretty good as it is. I run there almost every day. Paint the green markers in the
bike lane area and maybe put some share the road signs up. The intersection does NOT need to be “reconfigured” and it certainly does not need confusing roundabouts. The cross walks
with the hazard lights already slow people down. THAT was a great idea and probably not that expensive. People and drivers looking at the ocean and people watching slow people down.
This is not the area where there is a problem. The problem areas are Oak and Roosevelt for starters. People and bikes blow that stop sign daily. I watch it happen from my office. I am
sure there are other problem areas in the village that are not coming to mind right now. Spend the money on placing more officers in the area (Carlsbad Blvd and Oak) to slow down the
errant speeders driving north and watching for drivers blowing yellow and red lights on Carlsbad Village Drive and Marion and Jefferson. Also, Jefferson by Hosp Park is a terribly
dangerous road. THAT is an area that needs attention. Green market should absolutely be placed there. No one stays in the lines on that road. It’s ridiculous. There are cyclists and
pedestrians walking in the area all of the time. Also, why are there no street lights on that section of the road? Come on people. If you don’t live in the village or drive or walk the area
EVERYDAY you should not be making decisions for the area.

sure who came up with the idea of the Roundabout, but as I understand the way it works this is an
absolutely stupid idea. As I understand a Roundabout, the first car into the circle has the right of way
throughout the circle, A 4-way stop makes more sense than this. With a Roundabout, you are hoping
everyone judges correctly and no one is in a hurry, This is a well-used intersection. To me that alone
makes no sense, but I will provide the following reasons:
1.It is ugly
2.An accident is more likely than with a traffic light (or even a 4-way stop)
3. It is also heavily used by bicyclists so now who gets into the intersection first....a bicycle or a car.
4. It is also heavily used by pedestrians who will have more difficulty getting across the street than with a
traffic light which allows them the right-of-way.
I don't see any sense in putting a Roundabout on ANY intersection that is heavily used by cars,
pedestrians AND bicyclists. Roundabouts as I see their placement are in locations normally where traffic
is not heavy and there is very little pedestrian use. On Sunday I turned left on Tamarack onto Carlsbad
Blvd to go to Costco. Mistake! I avoided the freeway because it was heavy with traffic. Carlsbad Blvd
was worse. Both lanes were bumper to bumper going south. A Roundabout there would have been
crazy. Cars would have been slipping into the Roundabout before their turn and judging when your turn
was would be almost impossible. A Roundabout makes no sense at this intersection, unless I am missing
something. I have been driving 60 years (and most of it has been in the Carlsbad/Oceanside area) so I
know a bit about traffic patterns around here. Even if I am only making a right turn in a Roundabout, I
can't do it until I determine if the car that got in the circle before me is coming three-quarters of the way
around.
Okay, so that is my 3-cents worth!

We would like to give our feedback on the 2 proposals for the intersection of Carlsbad Blvd and Tamarack Ave.
We are totally against taking away one lane, and thus having vehicles travelling in 1-lane both ways, and as
such we vote for Option 1. We would LOVE to see a Roundabout, as that totally reduces speeding and accidents, but NOT at the expense of taking a vehicle lane away from each direction. The traffic currently is very high at this intersection, and eliminating one lane will create horrendous traffic backups.
If there was a way to have the Roundabout and keep the 2 lanes in both directions, that would have our full support. But short of that we vote for Option 1.
Thank you.

Hello!
My family and I live off Tamarack & Jefferson, thus we go through the intersection of Tamarack & Carlsbad Blvd
frequently—both as a motorist as well as a pedestrian.
I can not express enough to the city how much a roundabout in that location is NOT a good idea. A roundabout within
an intersection that is as pedestrian dense as Tamarack & Carlsbad Blvd is flat out dangerous and a very bad idea.
I know that the city is trying to improve traffic flow but a roundabout would only make traffic much worse with how
many people cross through that intersection on a daily basis. The busy cross walks need to be timed with traffic lights
and a 4 way stop for the utmost safety. If the crosswalks are not timed there will be a constant flow of pedestrians using
the cross walk one after another rather than grouping together which will greatly impede the flow of traffic. A
roundabout in this busy intersection with heavily used crosswalks will confuse drivers and potentially result in the death
of a pedestrian. If the use of the cross walk is not timed with the traffic lights it will back up traffic exponentially.
My family walks the sidewalk on the southbound, west side of Carlsbad Blvd frequently to go to the beach near tower 33
& I agree that it should be widened. I have two young children and see the reasoning and need for this. My family and I
greatly prefer the plan WITHOUT the roundabout.

Quick feedback on the proposed options for the Tamarack/PCH intersection. I'm the owner of
305 Tamarack Ave and am very familiar with this intersection both as a driver and pedestrian.
I think that option 1 is the only viable choice, because of the volume of pedestrian trafficespecially during the summer months. I think option 2 would result in significant traffic
congestion in that area far exceeding a stop light, because of the pedestrian flow in addition toreducing to only one lane. That would create a perfect storm for very undesirable traffic
congestion. Option 1 will make pedestrian crossing much safer than it currently is.

To whom it may concern,
As a long time carlsbad resident and someone who lives quite near this project, thank you for addressing the Carlsbad
Blvd and Tamarack crossing. This intersection is sorely in need of improvements and either proposed solution will
greatly increase accessibility for all. I am strongly in favor of Option 2 to make the intersection a roundabout for
multiple reasons.
Looking at Leucadia, Encinitas, Solana Beach, and our downtown village area here in Cbad, the more space we pull away
from cars and give to the people the better it is for making towns feel more like communities and also better for
businesses. More people are walking which means they’re more likely to stop into local shops and also drivers are going
slow enough to actually notice what shops and restaurants exist in the area. While this particular intersection is more
residential than commercial, making the area more pedestrian friendly will also encourage people to explore our
beautiful lagoon trail in addition to allowing easier access to Tamarack Beach.
Most importantly, roundabouts are shown to be safer and more environmentally friendly than stoplights.
“Roundabouts are a safer alternative to traffic signals and stop signs. The tight circle of a roundabout
forces drivers to slow down, and the most severe types of intersection crashes — right-angle, left-turn and head-on collisions — are unlikely.
Roundabouts improve traffic flow and are better for the environment. Research shows that traffic flow improves after traditional intersections are converted to roundabouts. Less idling reduces vehicle emissions and fuel consumption.
Roundabouts generally are safer for pedestrians. Pedestrians walk on sidewalks around the perimeter and cross only one direction of traffic at a time. Crossing distances are relatively short, and traffic speeds are lower than at traditional intersections.” (source: https://www.iihs.org/topics/roundabouts)
We need a roundabout at this intersection to force drivers coming from the south to slow down as they enter an area
where so many pedestrians are crossing Carlsbad Boulevard to visit our beaches. Less idling cars means less emissions and better air quality where so many tourists and locals love to spend their time. Every single change our city makes should prioritize pedestrian safety to encourage locals and tourists to leisurely enjoy our beautiful city.
Option 2 is safer, more environmentally friendly, and better for our city.
Thank you for your time,

We love the idea of the bus stop in front of our house being moved South, The roundabout which would be a huge improvement, and, hopefully slow the speeders, racing vehicle's,
help with the noise from loud vehicles exhaust, and only 1 lane would be so nice for our neighborhood. Widening the sidewalk would be helpful in front of the restaurant, as people
have to walk out in the street if 2 people are on the sidewalk.The only thing we ask is that you don't have street parking on the Blvd. in front of our house.
We have enough cars parking on Redwood, and the restaurant crowd parking on our streets. I feel we are disturbed enough by the restaurant, and cars.

I think this is not the best situation for a roundabout. I cross the street there often. I think that one lane will cause cars

summer especially. I think it would put people at risk. I favor other traffic calming installments that would slow traffic

Hello,
I noticed an issue with the statement regarding bicycle lanes and the roundabout option.
The table below implies that the bike width lane will be 7‐8 feet. It should be 0‐8 feet, because the bike lane completely
disappears in the roundabout, see below.
In the roundabout option, cyclists are pushed out into traffic and forced to merge with the thousands of cars per day
that use Coast Highway.
This is NOT a safe option. While cars would likely slow down, either due to narrower lanes or simply because all cars
would be sharing a single lane,
cyclists are going to be hard pressed to merge with that traffic. The design as shown below is a recipe for cyclist collision
with cars, and cyclist deaths. I implore
you to create a safer design for cyclists in this scenario.

I am writing to give comments on the proposed options put forward for the Tamarack/Carlsbad Blvd.
intersection. I am a 25-year resident of Carlsbad, and have a lot of experience with this intersection,
both driving and as a pedestrian. I lived a block from the intersection for 7-8 years (Garfield at Redwood), and now live just behind City Hall. I still walk from Carlsbad Village Drive to the power plant/Poseidon outflow channel at least once a week.
Overall, I appreciate that the City is working to improve the intersection and the sidewalks and
parking around it. I particularly like that the sidewalk over the bridge is to be widened with either option. While what's there works, it is narrow and squeezes pedestrian traffic. I believe that more pedestrians will use the route when it is widened, and fewer will resort to using the bike lane as an alternate.
As far as the main intersection options go, I prefer Option 1. In general, as a driver, I like roundabouts, but I do not think that it is a good idea at this intersection due to the large number of pedestrian crossings that occur there. I do not feel that roundabouts are a plus for pedestrians. The whole idea is that the drivers slow down, but do not have to stop. As a driver, one tends to focus on
the actions of other cars, and not on pedestrians. It has worked very well at Carlsbad Blvd. and
State, and I imagine that it will work pretty well at Carlsbad Blvd. and Cannon. But both of those intersections have significantly fewer pedestrians than at Tamarack. I realize and appreciate that Carlsbad has recently added more pedestrian crossing lights between Pine and Tamarack, and those are great, but pedestrian traffic at the Tamarack and Carlsbad Blvd. light will always remain heavy.
Thank you for the opportunity to comment.

Roundabouts are generally great as they covert a batch system to a continuous flow system. However, they have to be
large enough to swallow tomorrow’s traffic volume. A too small roundabout is a waste of money.

Hi Rachael Ross local business owner and a resident on the corner of Tamarack and Garfield.
I've read the proposal. I do like the idea of widening the sidewalk and bike lanes. I normallylove roundabouts but thier are a number of problems I see with putting one on Tamarack.
1. During summer months the foot traffic is high at that intersection. Traffic will back upbecause of constant pedestrian flow.
2. The danger to pedestrians mostly from motorcycles and fast cars not slowing down orlooking closely enough especially when making right hand turns.
3. I probably have had cars come at me at me and quickly brake at that intersection makingright hand turns over 300 times. I walk it every other day. I make eye contact with each car as
the pedestrian and wave to ensure my safety but I've seen tourist almost get taken out. Somereally close calls.
Some suggestions
1. Make the Tamarack PCH intersection like the one on Pch and Carlsbad village. With a noright hand turn light up sign when pedestrians are crossing and a diagonal cross.
2. Put a pedestrian light up cross walk at the corner of Tamarack and Garfield. Like the oneson PCH. That intersection has so much foot and bike traffic same issues.
Thank you for your consideration.

I prefer and support the use of roundabout intersections. However, there is a now a frequent rush hour back up
northbound on Carlsbad approaching Canon. For this intersection, It appears that narrowing Carlsbad at Tamarack to
one lane for a traffic circle would create the same long back up – likely all the way back into the Canon intersection –
when traffic merges from the two lanes between Canon and Tamarack. With that type of back up from the south, it
seems it would be difficult for traffic to merge onto Carlsbad from Tamarack due to the constant flow of northbound
traffic through the roundabout.

Subject:NO ROUNDABOUT!!!! Carlsbad Boulevard and Tamarack Avenue Intersection Improvements
The absolute last thing Carlsbad needs is a roundabout at Carlsbad Boulevard and Tamarack. It will introduce another
significant and unnecessary choke‐point on the coast. What are the results of the traffic flow studies for the
summertime, with out‐of‐towners trying to figure out a roundabout while trying to access the parking lot on Tamarack?
While local buses and traffic are just trying to move through?
This intersection is completely different than the one at State St, and WILL NOT work the same. I hate the State St
roundabout, but it serves as a “break” between Carlsbad and Oceanside. We do not need a “break” in the middle of
Carlsbad Blvd…the traffic backup will completely destroy any traffic flow on the road.
We need a traffic lane for north/south through‐traffic. We need a turning lane to get onto Tamarack and down to the
parking lot. We need a merging lane for buses into the north/south traffic; a roundabout would shove ALL TRAFFIC into a
single roundabout and paralyze the intersection.
Please publish traffic data for review, we need more than pretty pictures and renderings.

I would also like to see a crosswalk with flashing lights (similar to those north of this intersection) placed at the trailhead of Agua Hedionda Lagoon (just south of Tamarack Ave)
crossing the street to the bridge/beach. There are quite a few pedestrians (me included) who walk the lagoon and cross at this point. A flashing crosswalk would be much appreciated!

I live in Carlsbad and wanted to weigh in. I prefer the roundabout due to its efficiency, safety, and elegance. Traffic
lights just slow traffic and create the potential for frustrated drivers to speed up to try to "beat the light", which means
high speed collisions are more likely with the traffic light. Roundabouts slow traffic to keep the 'crazies' from going 85
mph, but they allow traffic to keep flowing when there isn't any cross‐traffic. This happens frequently ‐ I sit at
intersections probably 3 times a day waiting for the red light to change, while there is no cross‐traffic at all. Very
frustrating and so unnecessary. Let's be progressive and let traffic flow in a more natural and efficient way.

Please consider our input on the proposed changes. My husband and I have reviewed the mock up renditions of the
improved intersection vs using a roundabout in this location. We frequently walk this route and we see a roundabout as
a pedestrian and bicycle death sentence. LOL that is a little dramatic but not entirely. Roundabouts promote constant
flow of traffic but pedestrians and also bikes require a stop of traffic. A signalized intersection is more safe because
drivers are more accustomed to it. In a roundabout situation both pedestrians and bikers lose visibility to drivers
because drivers are more focused on maintaining flow. I hope you consider this point.
Best,

Subject:Tamarack/Carlsbad Blvd. traffic plan
Date:Monday, January 9, 2023 9:39:09 PM
Hello,
I'm a Carlsbad resident since 1974. A homeowner living on Sequoia Ave since 2001. My husband and I have raised
our two kids on Sequoia. When we remodeled in 2003, we made sure a front gate and a driveway gate was in the
landscape plan. We did this because our young children would play in the front yard, and it has never been safe.
Mainly due to the traffic flow and the speed of cars driving up Sequoia.
When I was in high school in the late 70s, we used to drive up Sequoia as a short cut to Tamarack Ave. Once I lived
on the street, I realized just about everyone did the same.
Prior to living on Sequoia, I lived on Garfield at Hemlock for 15 years. Needless to say, I've been in the
neighborhood for many, many years and personally experienced the increase of traffic, both pedestrian and auto, on
a daily basis.
Sometime ago I spoke to the City about making Sequoia Ave a one way street with traffic flow only going west.
Many of my neighbors would like to see the street closed off at Carlsbad Blvd. all together.
This new plan will severely impact my street, no matter what option is chosen.
The increase of traffic we will have on our street from a one lane round about is not acceptable. Not to mention the
lack of traffic flow on Carlsbad Blvd. Everyone will be driving up Sequoia to get out of the long line into the
roundabout. And angry drivers are a concern. I already see aggravated drivers on a daily basis, speeding up my
street to miss the red light at Tamarack.
I would like the city to take into consideration the amount of foot traffic crossing Carlsbad Blvd. to the beach.
People with surfboards, children, wagons, coolers, beach chairs, umbrellas, bbq grills, fishing poles, etc. How will
they safely cross in a roundabout and not impede traffic?
The city needs to consider other options. Both Cardiff and Solana Beach have walkways under the railroad tracks
for safer pedestrian crossings to the beach. Carlsbad should put a similar walkway under the bridge overpass, just
south of Sequoia. One that would start at the trailhead, under bridge, to the existing stairs at the Tamarack parking
lot. This would give pedestrians a safe place to cross and not delay the flow of traffic.
The flow of traffic in the village has worsened with the installation of the diagonal crosswalks. The single lane
roundabout in north Carlsbad creates traffic backup because the turn radius ia too narrow.
It's a very bad idea for the amount of traffic at Tamarack. Commuters use Carlsbad Blvd as a first option when I-5
is jammed north and south.
If the city chooses option 1, keeping the traffic signal, making no left turn from Sequoia going west and no left turn
onto Sequoia going south, I will propose to close Sequoia at Calsbad Blvd. from all incoming traffic.
See you at the meeting on February 6th.
Sincerely,
Stacy Foster Ferayorni

available to compare expected serviceability of roundabout vs signaled intersection? Data should be commensurate

I am supporting roundabout design but several citizens are concerned of traffic flow/ volume with narrowing of lane.

Subject:Carlsbad Blvd and Tamarack Project
Date:Tuesday, January 3, 2023 8:59:04 PM
Hi,
I’d like to offer perspective on the project for this intersection. As someone who has lived a block or
so from this intersection since 1994, an avid cyclist who travels this intersection regularly and as a
pedestrian going to and from the beach, there are some important insights I’d like to point out.
What I look for is to reduce the potential for tension and/or collisions between drivers, pedestrians
and cyclists. Being all three gives me a unique perspective that I think is worthy of sharing. I want to
break this down into northbound and southbound because Carlsbad Blvd is a downhill slope when
heading south and uphill of course when heading north. The slope dictates approach speeds
especially for cyclists.
1. Heading north: Cyclists go slower up hill than down. While avid cyclists go about 15+ miles
per hour through this intersection heading north, leisure riders will go maybe 8 to 10 miles
per hour. When either type of cyclist approaches the intersection as a roundabout, they must
“take the lane” to enter the intersection because of the narrowness of the entry point and the
elimination of the bike lane. Cyclists must look back and judge the speed of approaching
drivers before entering the car lane ahead of the roundabout. If timed well or in light traffic,
it’s not an issue. With heavier traffic or when a driver is traveling at a greater speed, the
cyclist entering the lane aggravates the driver understandably. At worst a collision occurs. The
roundabout creates a new danger that does not currently exist because of the elimination of
the bike lane and the protruding curb on the right which can be easily hit by a cyclist
navigating through the narrow passageway.
2. Heading south: Taking the same situation as above, now avid cyclists approach the
intersection at around 20+ miles per hour and leisure cyclists around 15+ miles per hour
because it is downhill. The narrow passageway and the elimination of the bike lane intensifies
the situation of the northbound side.
From a pedestrian point of view: As a pedestrian, I am mostly afraid of the cyclists. There are no red
light/green light indicators at a roundabout. Only the flashing yellow push button lights. As a
pedestrian when I cross into the crosswalk of a roundabout with one or more cars waiting, allows me
to confidently walk across. But the car or cars also create a visual blind to cyclists as they enter the
roundabout. I must then stop to see if the cyclist will stop, causing me to have the drivers waiting on
me to wait a little longer so that I can make sure I am clear to continue. The potential for collisions
between cyclists and pedestrians is elevated. Tension between pedestrians and drivers for “holding
them up” is elevated. I have seen situations like this as a cyclist. Leisure cyclists are less aware of this
danger and I have seen near collisions. We have our police doing their best to issue citations along
Carlsbad Blvd to protect pedestrians from cyclists. My point is why even introduce this new danger
in the first place. Police can’t protect every pedestrian at all times.
Feb. 6, 2023 Item #4 Page 271 of 324
I think having a definitive red light/green light intersection provides certainty to all three parties. I
am in favor of the traffic signal option because it provides more certainty and safety for all three
parties. The traffic lights sets the rules of who goes next versus leaving it up to the three parties. A
great example is the intersection of Carlsbad Blvd and Carlsbad Village Drive. All four entry points
have certainty for drivers, cyclists and pedestrians. There is greater peace and lesser conflict because
of the traffic signals and four way pedestrian 35 second all direction walkway. Even regular red
light/green light intersections provides greater peace because all parties know who has right of way
at every given moment. Roundabouts introduce random in my opinion.
I understand that the city might use the roundabout at Carlsbad Blvd and State St as a successful
example for Tamarack. Two things are different there versus Tamarack. One, it’s a three way versus
four way entry. And number two, it’s a steeper slope. A three way entry, especially this particular
three way is lesser volume than the four way entry at Tamarack. Based on my observation, the
number of vehicles entering from State St heading north is not nearly the volume as either main
entry point at Tamarack. I think the vehicle back up potential at a Tamarack roundabout would be
much greater than the State St roundabout. The slope of Carlsbad Blvd is important there because as
a cyclist heading north, the downhill provides the higher speed to “take the lane” much earlier on
the approach and at vehicle speeds which is much safer. Therefore, less conflict between drivers and
cyclists. Heading north, it is so steep, cyclists hitting the curb on the right at that pinch point is much
less likely by going so slow. Cyclists must still block vehicles as they enter the roundabout at slow
speeds though. No way to avoid that part.
Regarding the Sequoia Ave access, as a local I never take it westbound to turn left on Carlsbad Blvd.
The traffic makes this option much less desirable than going to the Tamarack/Carlsbad Blvd
intersection and wait through a full red light and turn left. Same for entering Sequoia heading south.
I never take that left. It’s much quicker for locals to take Redwood or Tamarack east off of Carlsbad
Blvd. The volume of traffic makes this choice much more pleasant and a faster way home. So, I don’t
think restricting the access to Sequoia under the traffic signal option is an issue. Given the
heightened vehicle back up lines with a roundabout, entering or exiting Sequoia becomes even less
desirable. Locals mainly only use Sequoia when heading northbound as a cut to Garfield St.
Overall, making the sidewalks wider is a great idea. This is especially true of both sides of the bridge
over the lagoon. Getting pedestrians out of the bike lane will reduce potential collisions on that
bridge as well. It will be much more prettier as well. If the roundabout idea prevails, I would highly
suggest finding a way to not eliminate the cyclist lane at the four corners of the roundabout and/or
not make the curbs so tight for cyclists to enter and exit the roundabout. These four corners are
where new problems will be introduced where they do not exist today.
Thank you for your attention.

Subject:Updated Carlsbad Blvd and Tamarack Designs Feedback
Good Morning -
Thanks so much for the opportunity to provide feedback to the subject matter.
As a Carlsbad Resident, since 1988, I have seen the corner of Tamarack and Carlsbad evolve. One thing
that has remained constant is the vehicular, and now bicycle and e-bike and pedestrian, traffic that has
remained ever present.
My wife and I had travelled, extensively, through Spain, Portugal and France. For a highway/roadway, as
busy as the Tamarack/Carlsbad Boulevard intersection, utilized round-a-bouts were of a much larger
scale, with two lanes of traffic revolving around the circle.
Throwing in bicycles, e-bikes and pedestrians into the size of the proposed Option 2 makes for "an
accident waiting to happen". Further, with no noted pedestrian signals, and with cyclists having to
"dodge" confused motorists who are attempting to enter and exit the circle is just not a logical plan.
One additional note, with Vigilucci's being right on the corner of this busy intersection, already difficult
access to their valet parking and their use of a drop-off point for their guests would be greatly
compromised. I realize that this is not part of the primary concern but, it will produce unnecessary safety
hazards.
Don't get me wrong, I enjoy traffic circles but, due to the size of the intersection, lack of pedestrian and
cyclist safety measures, I have to side with Option 1.
If you have any questions or require additional information, please let me know.
Respectfully,
Semper Fortis,

Having grown up in the east and driving with roundabouts, I personally think Option 2 is great, but
considering what I have seen with the lack of knowledge by local and visiting drivers on how to best use a
roundabout / circle- I would favor option 1 with a traffic light.
The roundabout entering into Carlsbad from Oceanside is a mess with drivers not familiar to the protocol of
using a roundabout; some of them race to enter others and look at it in dismay. Others just STOP.
What we really need in addition to a change is a traffic cop- directing traffic and handing out a ticket.

Subject:Regarding - Carlsbad Blvd & Tamarack Ave Intersection Improvement project
Hello,
I am a resident of Carlsbad, near where the above project is located. I spoke with Lauren Ferrell this afternoon to learn
more about this project. I am writing to encourage the project to move forward with the Traffic Circle option due to the
future slowing of this congested area as well as the safety issues and esthetics of this area. I also STRONGLY encourage a
crosswalk going from Sequoia to the other side of Carlsbad Village Drive. This is an area that is often “jaywalked” with
heavy traffic and dangerous consequences.There is good reason to widening the bridge in the area for pedestrians. Two‐
way pedestrian traffic when it involves small children, baby carriages and dogs gets extremely difficult. I applaud you
and your committees for their foresight.
Thank you,

Hello,
As a long time Carlsbad resident we prefer option one and the reason for that is having option two makes it
extremely difficult to cross the street as well as ride our bikes through the roundabout.
The roundabout at the end of Coast Hwy/State Street has been very difficult for us to use over the years, including
crossing without a car coming too quickly around the roundabout, as well as riding our bikes in the roundabout and
feeling like at any moment I’m going be hit by a car. Please don’t ruin what already works there with traffic flow
being great now. Our summers are busy and traffic will back up with continued pedestrians crossing at that location,
so how about option one and allow pedestrians to cross like you do at Carlsbad Village Drive and Coast Highway?
Thank you for listening.

To whom it may concern:
I am a long time Carlsbad resident that has lived here since 1995. I have carefully reviewed
the proposal options for the intersection of Tamarack and Carlsbad Blvd. (coast hwy). Frankly I nor my husband or neighbors find anything of value to change the current intersection. It
won't add value to our community and there's nothing wrong with the current intersection. Why spend the money when there's nothing wrong?
We all feel the money would be better spent on doing something about the teenagers using
their motorized bikes. Putting up electronic signs is NOT THE ANSWER! There needs to be an age limit to operate an electronic bike along with a driving test required for teenagers to
operate an electronic bike. I have seen numerous violations where kids drive in a lane for cars, they do not stop at stop signs/traffic signals, and I almost hit 2 kids on the winding road of
Jefferson that winds around the Buena Vista lagoon to Marron Road. They are BIKES and NOT a motorcycle! THIS NEEDS TO BE ADDRESSED ASAP BEFORE SOMEONE IS
KILLED!
Please consider spending the money where it can show the most value for the community and people's lives.

Lauren,I looked at the plans projected for the intersection at Carlsbad blvd
and Tamarack. I definitely and strongly urge the City to use Option 1for two reasons.
1) Traffic signal keeps traffic moving. Roundabouts are so outdated andpeople don't know how to use them. We will have traffic jams galore. A
very expensive way to get drivers frustrated!2) The Freeway, Elcamino Real, and Carlsbad Blvd. are the only means of
north- South traffic if the freeway is backed up( which it does severaltimes daily). or there is an accident.
A roundabout would only contribute to the congestion. I am suresomewhere in the near future there will be buildings built where the
power plant is and there will be a considerable traffic increase in thisarea. A roundabout would only contribute to the congestion.
I am for option 1 and totally against option 2 and any further use ofroundabouts in the city of Carlsbad.

Lauren,
Thank you for your recent mailer regarding this important intersection in our neighborhood. I
recognize this is a busy intersection and improvements can be made. We have owned our house for
about 18 years and have seen an increase in traffic and a few changes along Carlsbad Blvd. I feel the
best solution is Option #1 – Traffic Signal. The Signal provides a positive “Stop” in traffic which will
provide a much needed break in traffic on Carlsbad Blvd. for pedestrians crossing Carlsbad Blvd.
between Tamarack and Carlsbad Village Drive. This stretch of Carlsbad Blvd. has a tremendous
amount of pedestrians crossing with the aid of button operated flashing lights. Unfortunately, it has
been my family and our neighbor’s families experience that many drivers either ignore and or don’t
see the flashing lights, causing many close calls between pedestrians and vehicles. If a traffic circle is
installed, I envision a steady flow of vehicles which will only increase the difficulty in crossing
Carlsbad Blvd. Additionally, the Traffic Circle will also dump more east bound vehicle traffic from
Carlsbad Blvd. onto Tamarack causing a backup at the stop sign one block away at Tamarack and
Garfield.
The Traffic Circle would create another side issue. Decreasing signals will create an increase in traffic
volume due to, during heavy 5 freeway traffic, travelers would opt off the freeway and onto Carlsbad
Blvd. This is already an issue that will only increase with the Traffic Circle.
Please keep the signal and make improvements that don’t impact the quality of life for the local
residences.
Thank you,

1) there is a question about the buss stop. How about we eliminate this and every bus stop, as well as the totally empty
busses that drive all over? Cancel all busses with no ridership, and have anyone who needs public transportation to
apply for a city/county state funded uber account. that will save us all $/pollution/ time/traffic
2) round abouts are ok if they work.

Date:Friday, January 6, 2023 7:28:19 AM
Hello.
I am concerned about Option 2, that incorporates a roundabout at Carlsbad Blvd. and
Tamarack.
The rendering indicates that people riding bikes will be forced into traffic when proceeding
through the roundabout. This seems somewhat dangerous, because it assumes drivers will
respect the right of way of bike riders. A dedicated bike lane with a buffer would seem to
provide more safety.
This area also has many pedestrians. My experience has been that motorists oftentimes don’t
respect pedestrian signals, unlike a red light.
Thanks for the opportunity to provide input.

https://www.carlsbadca.gov/city-hall/meetings-agendas/boards-commissions/traffic-mobility-
commission
The roundabout planned/approved for Carlsbad Blvd and Tamarac Ave IS A VERY BAD PLAN. Because
there are no traffic lights at the roundabout, drivers will proceed without stopping if the circle is
empty of oncoming cars and will not stop for pedestrians. That is very likely given how 1) pedestrians
and bikers are less visible when crossing IN FRONT OF a roundabout, and 2) drivers are often pre-
occupied with the pretty ocean views and sidewalk activity at that spot. Second, because Carlsbad
Blvd is often bumper to bumper during both the morning and evening commutes, a driver
approaching from Tamarac to go south on Carlsbad blvd, for example, cannot get into the
roundabout to make that turn - traffic will be continuous. I've been in that situation numerous times
in roundabouts in Vista and no one lets you in probably because they think you will be 'cutting' into
their line - when you really only want to go in the opposite direction. Moreover, in a Vista
roundabout, I witnessed a horrible bike accident in which the biker was crossing the walkway in
completely stopped traffic (standstill in all directions - thinking it was safe)- the driver then got an
okay to enter the roundabout and -- boom - the biker was hit because the driver had waited so long
to enter the roundabout he/she was not looking to the right for the biker. But this situation would
not have occurred if there were street lights at the 4-way intersection because the lane in which
drivers enter would have been stopped. Please abandon this roundabout plan - it is very unsafe!

Also, a good way to spend $s….please consider restriping Cannon Blvd east of el Camino Real in the hotel/industrial

squeeze oncoming traffic closer together. Currently the bike lanes are hogging up too much space for safe vehicle

Subject:Fwd: Supporting Roundabout at Tamarack and Carlsbad Blvd
Dear Carlsbad Traffic Commission,
I strongly support Option 2, using a roundabout to improve the intersection of Tamarack and Carlsbad Blvd.
I regularly drive and bicycle throughout North County and I can clearly see the primary benefits for Option 2: improved
safety for everyone who uses the road: motorists, bicyclists, pedestrians, and others. The safety improvements from
roundabouts are well known as they reduce the number of conflict points, making the most dangerous head‐on and T‐
bone collisions between a motor vehicle and others virtually impossible. The accommodation for pedestrians in a
modern roundabout ensures pedestrians only need to look for conflicts in one direction as they proceed to/from the
pedestrian refuge in the splitter vane halfway. These safety improvements are important for your Vision Zero
aspirations.
Speeds will be reduced to a moderate 15‐20 mph: slower speeds through the intersection again make it safer for all.
Average travel times through a single roundabout will shorten trips and eliminate waiting at traffic signals, where idling
vehicles only add to pollution and noise, not to mention the aggravation of having to sit at a light.
Finally, your artist rendition for Option 2 shows how you can create not only a functional safety and efficiency
improvement but beautify an otherwise utilitarian road intersection. This will be a wonderful place to drive, bicycle and
walk, a model for other intersections along our North County Coast.

Carlsbad Traffic Commission:
I'm writing to support the roundabout option when reconfiguring the intersection of Carlsbad Blvd and Tamarack Ave.
I'm a former resident of Leucadia and longtime resident of La Jolla where we have five roundabouts in a row on LJ Blvd
in Bird Rock. There was a lot of debate and objection to that project too, but there is no doubt how effective
roundabouts are at traffic calming, slowing traffic, and improving safety, all while maintaining traffic throughput at a
high level. It's a win‐win‐win over traffic signals, all day long, every day. I have no doubt this intersection will see the
same advantages.
As a cyclist I must add that slowing cars down to the 15‐20 mph range, which roundabouts do, brings them down to
bike speeds, making in‐line integration of bikes and cars through the intersection feasible and safe, which is far better
than setting up riders for right hooks, left crosses and drive‐out crashes, as traffic signal intersections tend to do. We see
the roundabout advantages now on 101 in Leucadia, as well as in Bird Rock, and more and more other locations
throughout the county.
I look forward to seeing cars, bikes, e‐bikes all rolling through that intersection for years to come, safely yielding to, and
stopping for, pedestrians, as necessary.

Hello,
I’m writing to voice my strong support for the roundabout option at the intersection of Carlsbad Blvd and Tamarack.
I live on Tamarack and frequently bike through that intersection and find cutting across multiple lanes of traffic to make
a left turn onto Tamarack very stressful. A roundabout would be much safer and efficient for people on bikes and also
create a more hospitable zone for what is already a high pedestrian traffic area frequented by children and older folks.
If I can make a suggestion, with increased bike ridership more bike racks would be great at Tamarack beach both by the
upper sidewalk and down below at the parking lot.
I hope the roundabout is approved and thank you for making our streets safer for everyone.

I am writing to oppose your idea of a roundabout.
Carlsbad Blvd is far to busy to narrow down to one lane. The traffic backup would be very bad.
Also the round about would be far to small.
Remember, this isn't 1950 and a sleepy little town. It is a heavily traded road.

Basically ok as is except:
1. Should eliminate option to proceed straight from Tam down to beach;
instead, beach traffic should rt turn to 101 then uturn then rt turn to beach;
similarly, traffic from beach shld rt turn only.
2. Currently, there is too much foot traffic in the sb bike lane creating hazard
as bikers must swerve into motor traffic lane to avoid pedestrians. Should keep
pedestrians off bike lane.

I'm just sharing my input about a roundabout at Tamarack and Carlsbad Blvd. Merging 3 lanes into one line would be a
colossal disaster!
Also, I live on Chestnut and the people and students from Carlsbad High speed down my street continuously. I know
speed bumps aren't an answer because the speed limit is 30 but how do we begin to change it to 25 so something can
happen before someone gets killed? I just don't understand why something hasn't already happened to quell the
speeding.
Thank you,

Subject:Fwd: Tamarack project update
Date:Tuesday, January 31, 2023 8:19:01 PM
Gentlemen,
I received the below update from the city on the Tamarack project. To say I'm disappointed is anunderstatement. Cutting down from the planned 9 vertical deflections to 4 will certainly NOT havethe same effect on this corridor than what was originally intended and proposed. When consideringthe long stretch of road, the changes in elevation throughout that encourage speeding and the sheernumber of vehicles using this street as a thoroughfare, one doesn't need a traffic engineer to come tothe conclusion that there is no way the new design will have the same intended effect. Commonsense should prevail.
While I have yet to see the design, you specifically call out keeping the raised crosswalk atSunnyhill, which is easily the most unused pedestrian cross point on this proposed stretch of roadwhile making no mention of the other raised crosswalks which are so desperately needed wherethey were proposed. I am praying that those are still in consideration (at Valley and James). Should those no longer be in consideration, I would have to wonder why the sense of urgency tokeep the raised crosswalk at Sunnyhill over these other two locations near the schools and expectthe city to back up their findings with facts that are made public.
The speed tables that extend the entire width of the street pose potential parking issues as well ashave a negative impact to the many bikers that use this roadway. I'm interested to understand thepushback from the Carlsbad fire department on the cushions versus the tables that extend the widthof the roadway. The below excerpt is from the US Department of Transportation Federal HighwayAdministration on roadway safety:
Field tests have shown speed cushions to reduce general vehicle speeds while providing little to no delay to fire
vehicles.vi Speed cushions are being used in place of speed humps in many jurisdictions due to their positive reception
from fire departments. The following are examples:vii
Austin, Texas found speed cushions have only a minimal, if any, impact on emergency response times with a
less than 1 second delay experienced by most emergency vehicles.
In San Diego, California, fire vehicles can travel over the cushions at full speed with no delay (when driving in the
middle of the roadway).
I will plan to be at the meeting on the 6th to voice my concerns in person but I would love to hearback from you prior to the meeting. I guessing another community meeting should be in order as Ihave a strong suspicion the majority of the folks who showed up for the roundtables a few monthsago to support change will be very disappointed in what the traffic engineers have come back with.

Traffic and Mobility Commissioners -
First, thank you for your service to the City of Carlsbad community and beyond.
I understand the intersection design plans for Tamarack and Carlsbad Blvd are coming to theCommission on Monday afternoon. Since I am unable to attend, I wanted to share my support
for the roundabout option via email ahead of the meeting.
I had engaged in the community input effort previously and through that process shared mysupport for the roundabout option, but wanted to ensure that I showed my support as well
directly here to you.
Having additional roundabouts along this corridor is key for traffic flow and traffic calmingAND enhanced safety for all road users. The first roundabout installed more than a decade ago
at the north end of the city at State St and Carlsbad Blvd was majorly transformative in somany positive ways. I encourage you as a commission to support an additional roundabout
being considered at Tamarack and Carlsbad Blvd. it will benefit motorists, bicyclists, andpedestrians alike and will transform and provide an opportunity for the beautification of this
key location along this coastal corridor.
Again, thank you for your service and your efforts around more mobility choices and trafficsafety improvements.
My best,
Kristine.

Dear Traffic & Mobility Commission Members:
In connection with the Feb. 6, 2023, 4 p.m., meeting agenda Item - 4. CARLSBAD BOULEVARD ANDTAMARACK AVENUE INTERSECTION, CAPITAL IMPROVEMENT PROGRAM PROJECT NO. 6058,please find our community comments and input below:
We strongly disagree with the Carlsbad design team’s suggested selection of the Option 2 Roundabout
Alternative as the preferred alternative for the following reasons:
1) By simply driving north and south along the coast during a mid-week rush hour period, it is readilyevident that Option 1 – Traffic signal, and the 4-Lane road provided, is necessary and advisablecompared to the Option 2 Roundabout, considering the very high number of vehicles currently needingaccess to Carlsbad Boulevard, and utilizing this coastal roadway daily.
2) The Option 1 – Traffic signal, and the 4-Lane road provided with traffic signals, is also much safer than
the Option 2 Roundabout option proposed by the design team for pedestrians desiring to quickly and
safely cross this very busy intersection, including disabled pedestrians.
3) The Option 1 – Traffic signal, and the 4-Lane road provided with traffic signals, is also safer than theOption 2 Roundabout option proposed by the design team for pedestrians and bicyclists crossing when
the blinding sun slowly goes down in the early evenings at this intersection.
4) Finally, under the Option 2 Roundabout, how are westbound vehicles supposed to quickly and safely
transition onto northbound/southbound Carlsbad Boulevard during rush hour commuting times with heavy
traffic (i.e. an endless number of rush hour vehicles going northbound/southbound at high speed on
Carlsbad Boulevard, with no traffic lights or stop signs to assist the transitional traffic and pedestrians)?
Option 1 – Traffic signal, and the 4-Lane road provided, is again highly advisable compared to the Option
2 Roundabout option.
Thank you for your consideration. Respectfully,

Good morning,
I wanted to provide my opinion on the potential options for modifying the intersection of
Carlsbad Boulevard and Tamarack Avenue.
I have relocated to Carlsbad for work from Orange County January of 2022, so I have been living here for about a year. I have been commuting and navigating around Carlsbad using my
personal vehicle for the majority of the time, with reluctance. I have just recently sold my vehicle and made the shift towards using a bicycle as my primary mode of transportation due
to the presence of numerous bikelines and alternate transportation options that the Northern San Diego County Region offers.
My feedback for the intersection would be to choose the roundabout. The option reduces the
focus on cars, optimizes the flow of traffic, and provides additional space forbicyclists/alternate transport. I think continuing to emphasize alternate transport options
beyond cars will continue to have its desired effect of reducing car dependency.
Thank you,
Brett Schmidt

next to this intersection. I would love to see option 2 -Roundabout implemented. I
feel the traffic would flow better at this intersection and less vehicles would be
running the red light.
My only concern is where is the more street parking going? I would hate to see RVs
and cars parked across the street from us blocking our view of the sand and surf. The main reason we bought in this complex is because of the unobstructed views.
Thank you and I am looking forward to the final project.

Date:Friday, February 3, 2023 6:07:38 PM
(1)PLEASE don't put yet another roundabout in at this intersection. I have lived
here most of my life near the current roundabout at Carlsbad Blvd and State and,
regardless of what your statistics may show, I have seen and experienced far more
confused drivers and near accidents now than before the roundabout. (A) Out-of-
towners frequently do not have experience with roundabouts and the counter-intuitive
rules for how to use them. (B) So far Carlsbad has made roundabouts that are too
small and so mistakes made by drivers have immediate effect with little time for otherdrivers to accommodate the errors.
(2)Whatever you eventually do with the intersection at Tamarack, please do not
overly favor the convenience of foot traffic. Carlsbad already does way too much tocater to tourism, sacrificing the quality of life in the City for year-round residents. An
example of this would be the lights at Grand and at Carlsbad Village Drive and
Carlsbad Blvd, where the light cycles (including the walk signs) take so long that we
locals avoid driving at the intersections to save time.
Thanks,

Subject:Proposed changes to Tamarack
Date:Sunday, February 5, 2023 8:22:26 PM
Good evening:
I am very happy to see the proposed changes to the intersection of Tamarack & Carlsbad Blvd. Both proposals
definitely have benefits. As a 5-year resident of the area, I agree that widening the road, more parking, and
expanding the pedestrian walkway are wonderful ideas.
As a person who frequently walks my dog along the area, I heavily favor the proposal that has traffic lights, Option
1. Whenever I have tried to cross at the current pedestrian areas, even with the lights flashing, many motorists do not
stop. I currently only walk to the traffic lights to cross, as I feel like I’m taking my life in my hands at the other
pedestrian crossings.
In addition, while I understand that roundabouts have environmental benefits, most drivers don’t know how to use
the roundabouts safely. I drive to Oceanside frequently and have found myself stuck behind drivers who don’t know
how to merge. I’ve also seen cyclists almost get hit by cars whose drivers don’t follow Chevron lane rules. I’ve seen
pedestrians almost hit while trying to cross. With how heavy pedestrian traffic is at this intersection, I think we will
see many injuries, both from cars and from cyclists who will now not stop for pedestrians. The traffic lights will
force everyone to stop.
For public safety, the traffic lights are the best option.
Thanks,
Fran Prather

Without spending a lot of time criticizing the minutiae of these proposals, I think a traffic circle is a really bad idea for this location. Although the improved aesthetics are alluring, I think it would make this intersection a nightmare in summer. Consider that no one, not pedestrian, not cyclist, not driver will be constrained by anything other than their own sense of giving right-of-way where right-of-way may be due. I think we're talking anarchy here. In my opinion, it will make what is already what can be a difficult intersection to navigate much worse. Jim Harte

Hello,
I would like to personally and sincerely request that NO traffic circle be built at the
intersection of Tamarack and Carlsbad Blvd.
I own and live in a home at Chinquapin and Jefferson. I am raising my young family right herein this neighborhood where decisions like this matter a great deal for us. For us we walk at this
intersection multiple times a week and drive through it almost daily. Please no traffic circle! While I have seen traffic circles work in different parts of the world (I used to live in the
United Kingdom), here in North County San Diego and Carlsbad specifically I haveexperienced them to be consistently dangerous and inefficient because people don’t know how
to properly use them. No one here in Carlsbad can guarantee that this will be safe or moreefficient than a traditional intersection. Just by using the traffic circle north of the city, a
person can easily tell that people don’t know what they are doing (not acknowledging who hasthe right of way, varying/dangerous speeds - too fast & too slow, no courtesy use of blinkers).
I am so fearful that the amount of traffic (walkers, bicyclists, and motorists) is a perfect stormfor a tragic accident. The people involved might be me, my husband, or children. While traffic
circles may generally/statistically help vehicle flow, it doesn’t help when people are veryunfamiliar and don’t know how to use them. A traffic circle is not a good choice for the
Tamarack and Carlsbad Blvd intersection with a large amount of pedestrians, residents andvisitors, and those just passing through our beautiful city.
I am asking, begging, pleading that the City of Carlsbad and its residents choose to NOT place
a traffic circle at Tamarack and Carlsbad Blvd.

Date:Sunday, February 5, 2023 1:35:52 PM
Dear Traffic Mobility Members,
Unfortunately, my schedule prevents me from speaking in person at the February 6th, 2023 meeting. I’m writing to
endorse the roundabout proposal at the intersection of Tamarack Avenue and Carlsbad Boulevard. The Carlsbad
Police report validates our family’s, long-held belief; the driver who hit and killed Christine Embree in the
intersection of Valley and Basswood was distracted. The infrastructure in place at the time of the collision and in
place today did not require the driver of the vehicle that struck Christine to engage with the road. She was allowed to
operate her vehicle distracted. A roundabout at the intersection of Tamarack Avenue and Carlsbad Boulevard would
force a driver and a bicyclist to engage with the road. Not only must speed be reduced to maneuver in the
roundabout, but one must continuously be alert for merging traffic. We believe Christine would be alive today had a
roundabout been in place at the intersection of Valley and Basswood on August 8th, 2022. In my further review of
the artist’s rendition of the roundabout, I didn’t see flashing lights at the crosswalk south of Tamarack Avenue.
Possibly just an oversight. From personal experience, I know the lights assist with crossing Carlsbad Boulevard
north of Tamarack Avenue. Thank you for taking the time to read my endorsement and for volunteering to create
safer streets in Carlsbad.
Best Wishes,

From: Steve Linke
Meeting Date: February 6, 2023
Subject: Public comment on Item #4: Carlsbad Boulevard/Tamarack Avenue intersection roundabout
I was on the Traffic & Mobility Commission until a few weeks ago. I support roundabouts at
intersections that would clearly benefit from them. However, I would advise asking for more
information in order to make a data-driven decision in this case. There are still unanswered safety and
operational concerns that continue my “lukewarm” support for this particular roundabout:
• The lack of traffic controls for pedestrians, as well as the potential risk of bicycle-pedestrian
collisions on the sidewalks, raise safety concerns.
• The heavy mixtures of pedestrian, bicycle, and vehicle volumes raise both safety and operational
concerns.
• No details are provided in the staff report about the roundabout itself or the traffic analysis
methods. Given its apparent small diameter and the expected volumes of users, Federal
Highway Administration (FHWA) guidance indicates that this roundabout will not have enough
capacity, further amplifying operational concerns.
Please note the following data from the staff report:
• Daily vehicle volumes are about 21,000 (~85%) on Carlsbad Boulevard and 3,000 (~15%) on
Tamarack Avenue for a total of 24,000 vehicles traversing the intersection daily.
• In the weekday peak hour, 184 pedestrians, 109 cyclists, and 2,123 vehicles traversed the
intersection.
• In the weekend peak hour, 249 pedestrians, 211 cyclists, and 2,108 vehicles traversed the
intersection
PEDESTRIAN SAFETY
Roundabout advantage: At a single-lane roundabout, pedestrians only have to cross two vehicle lanes,
and there is an “island” refuge between them. The shortened crossing distance is safer than crossing all
of the vehicle through and turn lanes of a signalized intersection.
Disadvantage: There is no traffic signal to stop vehicle and bicycle traffic, so pedestrians just have to
wait for a break in traffic or start across the crosswalk and hope that traffic stops for them. This is
particularly unsafe for sight-impaired individuals.
The staff report indicates that this roundabout will be designed to accommodate potential future stop
controls for pedestrians, but that defeats the “continuous flow” concept of a roundabout and could
have significant operational consequences that are not addressed in the traffic study—meaning that a
conventional traffic signal may have been the better operational option.
Also, if cyclists fail to dismount and walk their bikes on sidewalks, pedestrians are at risk of being hit (see
below).
2
CYCLIST SAFETY
Roundabout advantage: The preferred method for cyclists to navigate a single-lane roundabout is to
merge into the middle of the vehicle lane as the bike lane disappears, and then go around in the middle
of the roundabout lane among the vehicles. This allows maximum visibility of the cyclist to create a safer
traverse through the intersection.
For cyclists who are not comfortable taking the vehicle lane, they can go up a ramp onto the sidewalk
and, typically, dismount and walk their bikes along the sidewalks and crosswalks until they re-take the
bike lane.
Disadvantages: Cyclists who are not comfortable in the center of the roundabout lane may stay to the
right of the lane, encouraging vehicles to pass them in the roundabout, which is very unsafe due to the
narrow lane.
Cyclists who are uncomfortable taking the vehicle lane at all are forced to take a far more convoluted
pedestrian route to traverse the intersection, and, if they refuse to dismount and walk their bikes on the
narrower sidewalks and crosswalks, they put pedestrians at risk of being hit.
POTENTIAL OPERATIONAL FAILURE
A single-lane roundabout can accommodate a larger volume of vehicles with shorter travel time
(continuous flow) relative to a traffic signal (stop and go) on a street with one lane in each direction—as
long as pedestrian interruptions are not high. However, when pedestrian, bicycle, and vehicle volumes
are high, a single-lane roundabout cannot handle as much as a traffic signal with two lanes in each
direction. And, when a roundabout’s capacity is exceeded, it can become a congested mess.
I was unable to find in the staff report any mention of the diameter (or the corresponding target speed)
of the proposed roundabout—or any of the other details or methods I had previously requested—even
though that data has to be used in a roundabout traffic analysis. So, it is not possible to assess the
validity of the analysis or the ability of the roundabout to handle the expected volumes of pedestrians,
bicycles, and vehicles.
Based on the renderings, I would estimate that the roundabout will be approximately 75 feet in
diameter, with a corresponding target speed of about 15 mph. This relatively small diameter (very few
vehicles can be present simultaneously in the roundabout) puts it in the category of a very small “urban
compact roundabout” or a large “mini-roundabout.”
Data published by the FHWA indicate that smaller roundabouts like this tend to have capacities (above
which “level of service” transitions from “E” to “F”) of only about 14,000 vehicles per day1—far less than
the 24,000 vehicles per day currently serviced by this intersection. And FHWA guidance on even much
larger roundabouts max out at around 20,000 vehicles per day2.
FHWA guidance also indicates that peak entries from one direction should not exceed about 1,150
vehicle equivalents per hour into this type of roundabout (and that is likely overestimated in this case,
3
because it assumes a minimum 80-foot diameter roundabout). However, peak entries are well over
1,300 per hour on northbound Carlsbad Boulevard. 3
It seems that some sort of metering traffic signal will have to be installed on the western leg coming
from the beach, but it is unclear the impact that will have. In any event, it is important to see the actual
roundabout traffic analysis to determine how this roundabout will somehow overcome the capacity
concerns indicated in the FHWA guidance. In addition, I think robust education and enforcement are
going to be necessary initially at this roundabout to keep pedestrians and bicyclists safe.
SUPPORTING ENDNOTES
These are derived from “Roundabouts: An Informational Guide (Second Edition),” Federal Highway
Administration.
1 “Exhibit 3-2: Planning-level maximum daily service volumes for mini-roundabouts.” The following
graph assumes roundabouts of 45 to 80 feet in diameter, which likely includes the proposed
roundabout. The left turn percentage at the intersection is about 5%, and the cross-traffic on the minor
street (Tamarack Avenue) is only about 15%, indicating that the rough capacity would be around 14,000
vehicles per day (blue line).
2 “Exhibit 3-1: Maximum daily service volumes for a four-leg roundabout.” The yellow line on the
following graph assumes a full-size single-lane roundabout (typically more than double the diameter of
the proposed roundabout with a correspondingly higher capacity). Even so, the daily volumes at the
proposed intersection are still higher than expected capacity, particularly after accounting for the fact
that the cross-traffic on the minor street (Tamarack Avenue) is only about 15%, and the fact that the
western leg contributes such a small volume.
4
3 “Exhibit 4-3: Approach capacity of a single-lane roundabout.” The blue dashed line is for “Urban
Compact Roundabouts” with diameters of 80 to 180 feet, so this analysis may overestimate capacity
relative to the proposed roundabout. Even so, the northbound Carlsbad Boulevard peak hour had 1,297
vehicles and 109 cyclists, which translates to well over 1,300 vehicle equivalents entering the
roundabout (“entry flow”), exceeding capacity. Note that the “circulatory flow” (other vehicles going
past that entry point to execute left turns) was about 120 vehicles.

First,
Thank you for the opportunity to provide input prior to the meeting on Monday 2/6.
Option 2 which takes us down to a single lane in both directions with the round-about will only back-up traffic into
the village which is the last thing we want especially during the summer & vacation months and all the events
Carlsbad hosts. Also the pedestrian crossings just prior to the roundabout seems to cause some confusion not to
mention MANY places in the US still have not embraced roundabouts so the tourists, which we have an abundance
of, may not know the proper yielding - again causing confusion, more back-up and potential accidents..
Our vote, along with our neighbors input, is for the traditional Traffic light option. The traffic light option seems to
support all the needs while keeping traffic moving in both directions with 2 lanes, adding an additional pedestrian
crossing and also providing additional room to pedestrians and cyclists.
Thank You again for allowing our input!

Hello All,
I am writing you with great concern about the U-turn this project has just taken. Every single
neighbor that I have spoken to is against this and the consensus among the neighborhood is extreme
disappointment with this team. These changes go against the goal of the project and weaken the
proposal to the point that it will not come close to having the effect we as residents had hoped for.
Our community attended multiple meetings and we spoke about the Fire Department and how they
had pushed back against this issue in the past, and we were told that had been resolved, clearly it
was not.
The Fire Department is located off Carlsbad Village, which does not directly expose any residential
properties and is bult as a thoroughfare from the 5 to El Camino Real for traffic with multiple lanes.
In addition, Cannon Rd is equally setup for fast traffic and in a non-residential are. One street is less
than a mile south of Tamarack and one is less than a mile north. With both of these street’s setup for
heavy traffic and high speeds, why would you keep targeting the exposed residential neighborhood
on Tamarack which are literally speeding right through a school zone.
There are over 20+ young children that live on my block of Tamarack between Highland and Park
including the James street corridor. All these kids are Middle School age or younger and traverse
Tamarack at great risk multiple times day. All residents in this area use the dog run located next to
Valley Middle School and directly out from James street where it intersects with Tamarack. Not only
residents, but there are soccer, lacrosse, football, rugby and more organized kids sports going on
every weekend in the Valley Middle field, which sits directly on Tamarack. Removing the proposed
raised crosswalk at Tamarack and James goes to show that this public relations team and the
engineers working this project do not understand our concerns as a community.
When drivers get to the stop sign at Highland and Tamarack going east that is the exact start of the
problem. 90% of our traffic problem is due to drivers using this as a launch ramp due to the steep
decline and this is where most speed is generated going east. This impacts not only the residents on
this entire Tamarack corridor who have kids at the schools and/or use the dog run next to the field,
but also the residents in the James/Jeanne corridor and the entire weekend crowd of parents,
grandparents and kids who come for the sports. Every single time anyone wants to cross Tamarack,
they have to wait and dart across the busy street as cars come flying down the hill off Highland, this
poses the most dangerous threat to the neighborhood as this is the crossing spot for field sports,
school access, dog walkers and most activity at Valley Middle School. We need this raised cross walk
at James and Tamarack for the massive safety risk the hill at Highland poses to the community and
seems to encourage the high speeds for which this entire project has been tasked to address. I see
close calls and drivers gunning it down this hill every day. The newly proposed speed table between
1539 and 1549 will do nothing to help.
I have three young children all under eight years old and this is beyond infuriating. We need to
advocate to protect our residents but especially our children. In this corridor of Tamarack we are
within two blocks of Magnolia Elementary, adjacent to Valley Middle School and three blocks from
Carlsbad High School. We are in a school zone, but you wouldn’t know it. We do not need to be
using Tamarack as an emergency vehicle route when we have Carlsbad Village and Cannon on either
side. The Fire Department is located off Carlsbad Village, which does not directly expose any
residential properties and is built as a thoroughfare from the 5 to El Camino Real for traffic with
multiple lanes. In addition, Cannon Rd is equally setup for fast traffic and in a non-residential as well.
One street is less than a mile south of Tamarack and one is less than a mile north. With both street’s
are setup for heavy traffic and high speeds, why would you keep targeting the exposed residential
neighborhood on Tamarack and allowing drivers to speed right through a school zone? I fear all the
goodwill and positivity that we all felt over the last 5 or so months is coming to an end as we see the
bureaucracy creep in.
You are choosing saving seconds of time for emergency vehicles (which studies into speed cushions
have proven their impact to be insignificant when taken into account overall emergency response
times) by sacrificing the safety, well-being and neighborhood feel of all of these Carlsbad residents.
We as home owners have been through months of meetings, emails and advocacy to get this done.
The approval from residents was near unanimous for the proposal prior to the changes. Everyone
I’ve spoken to since the email is furious and feel as though the rug has been pulled from under us yet
again and the typical bureaucracy from the city departments has taken over the will of the people.
The change from the speed cushions to the speed tables is just another softening of what was given
to us and supported by the residents. This change is a big impact and lessens the intention of the
initiative once again, it makes no sense especially based on the studies such as referenced by my
neighbor Jason Oziel that show that this change isn’t needed and the time saved is not significant.
Removing over half of the proposed deterrents weakens the project and does not come close to
addressing the point of the issue, we need to force people to slow down not hold their hand and
gently suggest it. We have the chance to do this right and it looks like you are choosing not to.
It seems you are catering to traffic over people, the antithesis of this Carlsbad traffic Safety Initiative.
I will be in person, along with many fellow residents, at the Monday meeting to discuss all of this and
hopefully come back to the plan that we had all agreed worked.

We live next door to vigillucies, and are in favor of the round a bout due to noise, speeding
and street racing. However, we do not want parking on the West side (South bound) of the
street, across from our house. I see the bus stop going South, will be moved to the North
about 150 feet, from where it is now located. We can live with that, but we have enough
traffic congestion from the restaurant to have to put up with any more.

City of Carlsbad Mayor, Council and City Staff:
We strongly disagree with approving any roundabouts on Carlsbad Blvd. Removing lanes
provides a disservice to the community as a whole. Our beaches should be accessible for all and not just those that live close enough to walk or bike. The design will not only further
impact drivers but also impact emergency response. Why should cyclist have precedence over drivers on the roadway when realistically there are more vehicle commuters. It is more
dangerous to have cyclist move into a busy single sharrow lane and through the roundabout with vehicles than it is to keep separate. As a driver of a vehicle and cyclist, I feel more in
danger with Option 2. If you must improve the intersection, go with Option 1.
Thank you,

Having been a cyclist almost as long as Carlsbad has been a city, having cycled around the world in 60 countries, having been through traffic circles big (ARC DE TRIOMPHE) and small (Leucadia and Hymettus), having been dealt with every indignity that can be doled out to a cyclist, I have the experience to advise that any traffic circle that does not fullyaccommodate unfettered flow for a cyclist guarantees an accident.
Do not take this lightly. I inform all cyclists, especially those from other countries, that the United States is the most dangerous place to ride a bicycle. This is because of the inattentiveness of motorists in this country, at best, and utter disdain as typical. Do not ignore this poor assessment of motorists. And to make matters worse, this is a tourist town and tourists are at their worst.
That said, there is insufficient space for a proper traffic circle.

Dear Traffic and Mobility Commission,
Thank you for the opportunity to discuss the intersection at Tamarack and Carlsbad Boulevard.
The drawings you shared for two possible solutions to this intersection are quite varied. One shows the “round-
about” configuration and the other shows the “crosswalk” solution.
Here is my take away on both drawings.
Round-about:
This intersection is a TIGHT intersection to begin with. Now, add in a bike lane and a car lane that merge on
approaching the roundabout. If I were a bike rider, I would not be comfortable at all merging with cars onto a
roundabout. Then, consider this…. It’s a typical weekend, or just a beautiful day to go to the beach. You’ve
amassed your family and friends with all of your beach equipment….wagons, strollers, surfboards ,etc. You all are
waiting for a safe break in the roundabout. The little ones are rambunctious, the moms and dads are looking right
and left. One of the children too anxious to wait, breaks from their parents’ grip and steps or runs into the street.
Notice, because it is such a limited space between the sidewalk and the road, it’s very possible a bike will hit the
child or, a car will.
Obviously, my concern, as your concern is, the safety of everyone. I do not think this plan is safe in the least.
The second plan gives a little more room for crowds that enjoy our weather and beaches, to safely cross. The bold
blinking lights are the better of the two options. There is a CLEAR opportunity to cross safely.
Please consider my thoughts. Carlsbad is a family city, not just a bicycle community. Both groups have more of a
chance to be safe with this plan.

Joanne Melton

I strongly support installing a roundabout at the intersection of Tamarack and
Carlsbad Blvd. Roundabouts have been shown to greatly reduce t-bone crashes
between vehicles. They also help to slow traffic which decreases the chances of
severe or fatal crashes involving pedestrians and bicyclists. Roundabouts also help to

Hello Commissioners,
My name is Steve Shepherd, and unlike most of those emailing you on this topic, I am not a resident of Carlsbad, but rather a public works appointee and safe streets advocate from a
different coastal California city.
I am taking this opportunity to email you because I've seen the benefits of roundabouts and their effectiveness in both calming vehicle traffic and promoting a smooth and safe vehicle
flow. This is a complex intersection that lends itself to the safety provided by a roundabout as compared to a standard traffic signal. In addition, it is quite clear that the Roundabout Option
provides better safety and more opportunities for those walking, biking, or rolling along this wonderful beachfront boulevard.
When we seek to modify our public rights-of-way, the decision on how to proceed often
comes down to our priorities, and while many blindly prioritize standard improvements simply because that's the way it's always been done, I urge you to look further. I urge you to prioritize
increased safety and accessibility over just "following along." I urge you to select the design that reflects the values of your community.
Please look beyond that which has always been and select something that can be better.

Option 1 is OK, not optimal.
Option 2 would be a disaster, another Bar Pavillion in the making. Squeezing all the
traffic on the Coast Highway down to one lane, shared with selfish bike riders, with a
roundabout?? With people wanting to cross Coast Highway to boot?? This will cause
a major traffic jam! Roundabouts can work well where there is light traffic with very
little foot traffic, but it won't work here...WAY to congested. Plus, bike traffic is
directed up onto the sidewalk here? I know that is not the intention but that's how it is
drawn out.
I have been a Carlsbad resident for nearly 37 years and I drive through this intersection
2-4 times everyday. Option 2 is a very poor design.

Dear Commissioners,
I’m writing on behalf of the San Diego County Bicycle Coalition to comment on Item Four of the
Monday, December 5th meeting of the Carlsbad Traffic and Mobility Commission: Carlsbad
Boulevard and Tamarack Avenue Intersection, Capital Improvement Project No. 6058. We
would like to state our strong support for the roundabout option.Without question, a
roundabout would be the safer option for drivers, bicyclists, and pedestrians alike and
would allow for smoother traffic flow while creating a more vibrant public space along
Carlsbad’s Coast.
Reasons to Support a Roundabout
While single-lane roundabouts are almost always safer than traffic signals, we believe the
roundabout that staff are proposing at the intersection of Carlsbad Boulevard and Tamarack
Avenue is particularly well designed and deserving of the support of this commission. We would
like to break down the reasons why we support this roundabout into four categories:
1. Proven safety data
Decades of research have confirmed that roundabouts are safer than stop or signal-controlled
intersections.Studies in the United States have found that installing roundabouts in the place of
traffic signals leads to 35-47 percent reductions in all crashes and 72-80 percent reductions in
serious injury-causing crashes. However, not all roundabouts are created equal– without certain
safety features, some roundabouts can be more dangerous for cyclists and pedestrians. As we’ll
explain later, though, the roundabout proposed in Carlsbad has safety features that particularly
benefit cyclists and pedestrians.
2. Roundabouts physically calm traffic
Traffic signals ultimately rely on drivers following the law to protect other road users. If a driver is
impaired, distracted, or purposefully noncompliant, there is nothing preventing them from
blowing through a signal and colliding with other road users in the intersection at high speed.
Roundabouts, in contrast, force all drivers to slow down by making them navigate around a fixed
object in the middle of the intersection. Roundabouts designed to accommodate bicycle and
pedestrian traffic– like the one proposed at the intersection of Tamarack and Carlsbad– should
have a design speeds of 15-20mph, meaning the angles to navigate the roundabout are sharp
enough that drivers cannot comfortably pass through at higher speeds. Regardless of a driver's
intent or state of impairment, well-designed roundabouts should make it impossible for them to
blow through an intersection at high speed.
Slowing drivers down is crucial, because speed is by far the highest factor in determining
whether a pedestrian or cyclist will survive a crash. While the odds of a pedestrian dying are
only 10%if they are hit by a car traveling 20 mph, those odds increase to 75% when a car is
traveling 50 mph. With a signalized intersection, we could expect drivers to regularly speed
through at 50mph on Carlsbad Blvd. A roundabout would make those speeds impossible.
3. The proposed roundabout creates space for a complete street
In the two alternatives presented for Carlsbad Boulevard, the roundabout option is proposed to
have one lane in each direction, while the signalized option would have three lanes. Staff have
informed us that both of these designs are projected to allow for similar traffic volumes and
similar travel times.
This lane reduction is absolutely crucial for the safety of cyclists and the activation of this
section of the Carlsbad coast as a public space. While the signalized, multi-lane alternative only
allows for extremely narrow, 5-foot bike lanes along the gutter, the roundabout option creates
enough space for 8-foot bike lanes with 3 foot buffers in each direction. Five foot, unbuffered
bike lanes next to multiple lanes of traffic are only comfortable for the most experienced cyclists;
8 foot buffered bike lanes with wide buffers would be comfortable for almost everyone.
Additionally, single-lane roads are much safer for all road users than multi-lane roads.
Regardless of the posted speed limit,studies have shown that drivers drive much faster on
multi-lane roads than single lane roads. As mentioned earlier, speed is the largest factor in
whether a crash is fatal, so slowing traffic speeds is an essential safety strategy.
Finally, the lane reductions enabled by the roundabout would create radically more space for
pedestrians. The traffic signal option would maintain the existing 5-foot sidewalk width. This
current width is far too narrow to accommodate the many people who walk along the Carlsbad
Coast, which causes many joggers to run in the bike lanes instead, creating a significant crash
risk. The roundabout option would allow for the creation of 10-foot sidewalks along the coast,
creating space for the many people who already walk the coast, and creating space for more
people to enjoy this natural resource.
4. The proposed roundabout would create comfortable options for cyclists of all
confidence levels
While all roundabouts are safer for drivers, roundabouts must be designed with cyclists and
pedestrians in mind to be safer for them as well. Carlsbad’s proposed design thoughtfully
considers the needs of cyclists of all comfort levels.
Cyclists would have two options when approaching the Tamarack and Carlsbad roundabout
from the bike lane. If less confident interacting with traffic, they could merge right onto the
multi-use path adjacent to the roadway, allowing them to cross the next leg of the intersection as
pedestrians. If more confident, they could merge left into the general-purpose lane, allowing
them to navigate the roundabout as a vehicle. With a design speed of 15 mph, commanding the
traffic lane as a vehicle would be comfortable for most cyclists. After the roundabout, both
options allow cyclists to merge back into the bike lane to continue.
This design is fantastic, because it anticipates the needs of both experienced and inexperienced
cyclists. Moreover,studies have shown that this specific design is safer for pedestrians, cyclists,
and drivers alike.
Possible Improvements to Design
While we are enthusiastically supportive of the roundabout option, there are three possible
design amendments that we believe could improve the safety of the roundabout.
First, the proposed design includes a slip lane that allows drivers to turn right from the beach
parking lot to Carlsbad Boulevard without entering the roundabout.Slip lanes encourage drivers
to turn right without slowing down, and introduce an additional conflict point for pedestrians as
they cross the street. Moreover, the traffic volumes coming out of the parking lot into the
roundabout would most likely be relatively lower than those of any other leg of the intersection,
so the traffic justification for the additional slip lane is unclear.This slip lane should be
eliminated to increase bicycle and pedestrian safety.
Second,research has shown that for cyclists crossing roundabouts as pedestrians to be safe,
drivers must be given clear visual cues that cyclists may be present. The current rendering
shows cyclists simply merging onto the sidewalk/ multi-use path prior to the roundabout and
crossing as pedestrians.To clearly indicate that cyclists may be present, the section of the
multi-use path intended for cyclists after the merge should be brightly marked in green
paint and the path of cyclists across the roundabout legs should be marked with bright
green conflict striping.
Third, while merging less confident cyclists onto the multi-use paths is a safe design, the
multi-use paths adjacent to the roundabout should be widened as much as possible to allow for
a clear striping separating bicyclists and pedestrians while giving both ample space to
maneuver.
Conclusion
Thank you for taking our recommendations into consideration. As always, we appreciate
Carlsbad’s regional leadership on building streets that are safe for all modes of transportation.

Subject:feedback for the Tamarack Intersection Safety Improvements
Date:Thursday, February 2, 2023 11:07:13 PM
Hello,
My family has lived in the 101 neighborhood between Tamarack and Pine for 18 years. We
often use the pedestrian crossings at and between these streets daily if not multiple times perday. My young children and I have nearly been run over in these crossings at least once a
summer, and my husband often has to yell to get the drivers' attention while we are in themiddle of the crossing, to make sure we can finish crossing safely. Two particularly close-calls
happened at the northeast corner of the Tamarack intersection.
We are all strongly in favor of the roundabout option for this intersection. Not only will it limitthe amount of lanes we have to navigate when crossing the street, but will help make the cars
more aware of pedestrians and hopefully put drivers in a "yielding" orientation.
Further, it will keep traffic flowing smoothly, which will improve general congestionthroughout the neighborhood. The only drawback I can see is that people want a chance to
admire the ocean view and a stoplight gives them the pause to safely do that. But overall, thesafety gains of a roundabout far outweigh any negatives.
Here are my children's votes in favor of the roundabout, in their own words:
Bear (age 12): "There's not as many crashes when there's roundabouts. A roundabout would be
a lot nicer, instead of a straight road. I like roundabouts, they're more efficient."
Keyoni (age 11): "I think that roundabouts would be good because we've almost been hit manytimes when we cross that road and the roundabout could really help with that. Roundabouts
are a very efficient way to move traffic and I love going around them when we can. I thinkthey're really helpful and it could get a very good look on Carlsbad and I would love going
down to the beach and crossing at the roundabout."
Whitley (age 7): "I want the roundabout because it's fun to go around it."
Thank you for the chance to offer our input!

Date:Thursday, February 2, 2023 3:43:53 PM
Dear Traffic and Mobility Commission:
Regarding the potential changes to the Carlsbad Boulevard and Tamarack Avenue intersection, I implore you to
make safety the priority and opt for the three/four-lane with traffic light instead of a roundabout.
With the numerous pedestrians and cyclists, especially during the summer, a roundabout at that location is an
invitation to disaster. A roundabout to keep traffic flowing is good in theory, but as witnessed at the roundabout at
the north end of town, few people understand how to use one properly; I have seen numerous close calls that have
placed individuals and vehicles at risk.
A likely response to traffic back-ups caused by heavy pedestrian use (beach access) in crossing areas of a
roundabout is for drivers to use neighborhood streets as an alternative, again risking pedestrian safety.
In my opinion the best solution is to provide a traffic light as at the Carlsbad Village Drive intersection with all
pedestrians crossing at the same time.
A further suggestion is to install flashing lights in the crosswalk pavement at ALL beach crossings, as all too
frequently drivers ignore the lights on curb and median signs.

Date:Monday, February 6, 2023 12:58:04 PM
Hello,
Being as I may be late to today's meeting and I want my comments on the record, I am
including in written form in case I miss the public comment portion.
I am 100% against a roundabout at the intersection of Tamarack and Carlsbad Blvd. I amactually a fan of roundabouts in general and do agree that they tend to keep traffic flowing and
reduce friction points. HOWEVER, they are not a cure-all and aren't always the right option. I strongly believe this case falls into that category where a roundabout is absolutely the
WRONG solution.
The city is trying to use the success of the roundabout at the north end of town to glorify whatto expect at this intersection. That would be like trying to compare and apple to a banana.
There are nothing alike except that they are both fruits! The existing roundabout doesn't haveanything remotely close to Tamarack in terms of pedestrian (particularly youth) traffic.
Tamarack and Carlsbad Blvd is one of the most heavily traveled intersections for pedestriansin our city. In my view, this factor alone makes it a poor candidate for a roundabout. Most of
the studies that have been done on roundabout safety refer to vehicles and speak in generalterms about improved pedestrian safety as a result of generally slower speeds. However they
fail to address the nuances that this intersection experiences such as the volume of pedestriantraffic, large cyclist groups (you know, the spandex crew), youth and adults on e-bikes,
skateboards, and more.
In the documents presented as part of the agenda packet, it was stated that pedestrian countswere done over three days (one Thursday in May and 2 Saturdays in June). Anyone that has
spent any time in Carlsbad knows that is NOT the busiest time where we have the mostpedestrians using this stretch. Our beaches don't get packed until July and August! Also, the
times this data was collected was from 11 am to 12:45 pm on the Saturdays. That sure seemspretty limited and not a good representation of what happens throughout the day.
What is going to happen when the state lot at the end of Tamarack is jam packed with people
trying to find parking and the entrance is backed up the hill? This happens regularly in thesummer before the cones come out and close off access. With only one lane feeding into the
lot from the north, if this lot gets backed up, there is no way for traffic to flow through theroundabout and continue south.
What is going to happen when there is a pedestrian or biker that gets hit in the roundabout and
needs assistance? How will traffic be impacted with emergency vehicles. There will not beanother lane to go around.
With the lanes of traffic merging into one lane through the roundabout, the bike lanes will be
merged into traffic lanes to go through the roundabout. Many casual bikers as well as youthriders are not comfortable navigating that process. The proposed project encourages bikers
who are not comfortable using the vehicular traffic lanes to access the sidewalk via the rampsputting them in the direct line of travel with many pedestrians. This will no doubt cause more
conflict points than what is reflected in your renderings.
What is going to happen when a 14 year old comes barreling down Tamarack Ave to get tosurf PE on his/her ebike and cruises right into the circle if they perceive even the slightest of
gaps in traffic (you know that will happen) and there are pedestrians trying to cross as well? Itsounds like an accident waiting to happen.
There have been ZERO serious accidents at this intersection in the last 12 months. While I
agree that improvements are needed to make all users safe no matter the mode oftransportation, the roundabout is not the answer. Option 1 still widens sidewalks, provides
safer pedestrian crossings, and would be a major upgrade to the current configuration. It hasmy vote!

Dear Commissioners,
My name is Laura Keenan. My husband, Matt Keenan, was killed 16 months ago while riding
his bike. He was only 42 years old and father to our then 15 month-old son. Since his death I've gotten very involved in safe street advocacy and last year I founded Families for Safe
Streets San Diego. We're a group of families whose loved ones have been killed in traffic crashes or are survivors ourselves. All of our members' loved ones were killed while walking,
biking or scootering. We advocate for safe streets in San Diego County to save lives and other families from our pain. I am a resident of San Diego and worked for many years in Carlsbad. I
have many friends in Carlsbad and am up there regularly.
Thank you for taking the recent crashes in Carlsbad so seriously. I look forward to seeing safer streets throughout the city. I'm writing to voice my enthusiastic support for a roundabout at the
intersection of Carlsbad Blvd. and Tamarack Ave. Roundabouts save lives because they limit the top speed of cars; they are proven to reduce serious or fatal crashes by up to 80%. The
woman who hit my husband was going at least 35 mph. He didn't have a chance even though he was doing everything right, riding in the bike lane with his helmet on and using the
brightest lights possible. He died on the scene. It is impossible to drive 35 mph ina roundabout, but it is easy to drive through a traffic light at those speeds or faster. Like many
cities in San Diego and the US, traffic safety is an emergency in Carlsbad. Please prioritize lives and choose the safest option.
In addition, I know there's concern that roundabouts will create congestion and add to total
travel time. However, that is not true. Since roundabouts allow for yields, rather than stops, travel times are not longer even though the top speeds are reduced. They allow for a more
continual flow of traffic.
My husband would be alive today helping me raise our son and seeing him grow up if the driver who hit him was going 15 mph, the speed this roundabout design dictates.
Thank you for prioritizing lives by choosing the roundabout option. I and all of the Families
for For Safe San Diego thank you.

Hello,
My name is Nicole Matteson and I am currently a Master of Urban and Regional Planning
candidate at UCLA who researches bike lane infrastructure at UCLA's Institute ofTransportation Studies under the mentorship of Dr. Adam Millard Ball. I was raised in
Carlsbad and grew up on its beaches.
After reviewing the proposed designs for the intersection improvement at Tamarack ave andCarlsbad blvd, I have some questions and concerns. I would have loved to join the public
meeting tomorrow, but I have a Bike and Pedestrian Planning class at the same time (ironic!).
My comments are as follows:
1. What is the intention of this project if it could be narrowed down to one thing? Iunderstand this is hoping to relieve traffic and be part of your "complete streets"
initiative, but often it is impossible to accommodate drivers, bikers, and pedestrians inone project- one must make sacrifices. It is better to do one thing really well instead of
three things poorly. If your intention is to make the intersection safer for bikers, whydoes the roundabout not have a separate (buffered at least) area for bikers? The
roundabout is incredibly large, there are ways to protect bikers without them merginginto a shared lane, such as an external colored bike lane that lines the perimeter.
2. If the intersection changes to one motor vehicle lane in each direction, where does themerge occur and how do you plan to reduce congestion at that merge? Do these designsreflect traffic predictions well into the future?3. If your intention is to reduce traffic, will there be any infrastructure and qualityimprovements made to the bus service on this route? I understand the bus stop hasmoved and has a pull out. Will there be a shelter added to the bus stops to protect transitriders from extreme heat? Have you considered a dedicated bus lane? Perhaps adedicated shared lane for bicyclists and buses? The only effective and long termsolution for reducing vehicular traffic is getting people out of their cars. I understandtransit ridership in Carlsbad is not ideal, but how can we make transit more desirableand easy? Bus riders are not second class citizens, we must change that stigma to trulyimprove traffic congestion and mobility in Carlsbad. It would be silly to invest so muchmoney into a project that will only temporarily improve traffic flow now, but not a fewyears down the road.4. Have you considered a parking protected bike lane? This will create a physical barrierbetween vehicular traffic and bicyclists which is safer for both bikers and drivers.5. I see that it is a goal of this project to add more street parking to Carlsbad Blvd. Istrongly recommend against this and believe any additional street parking along thecoast will not improve vehicular congestion in the near and long term. It would be idealto instead introduce a dedicated beach parking area off the main road. This way beachgoers could park and walk a short distance to the beach while enjoying the newpedestrian infrastructure. If the goal is to reduce vehicular congestion, we should beproviding alternative places for vehicles to park. This will promote active transportationand improve pedestrian and bicyclist safety.6. Regarding option 1, have you considered reducing the width of the inner vehicular lanesto 9.5-10 ft and the turn lanes to 9 ft? Research has shown that vehicle lanes areunnecessarily large and that reducing their width can actually improve safety because itmakes drivers become more cautious and aware. This would free up at least another footthat can be added to the bike lanes, with priority going to the south bound bike lane.With the rise of electric bikes, we need bike lanes that can accommodate both electricbicyclists and traditional bicyclists. Electric bikers may need to pass traditional bikersbecause they can reach higher speeds. Adding more space to bike lanes can providepassing room without needing to enter vehicular traffic.
If there is a recording of the meeting I will look forward to watching it, but if not I plan to readthe minutes of the meeting. Thank you very much for your time and consideration of mycomments, I look forward to more opportunities to discuss infrastructure investments inCarlsbad!
All the best,Nicole MattesonMaster of Urban & Regional Planning Candidate,Class of 2023, UCLA

Subject:Support for Roundabout at Carlsbad Blvd and Tamarack Avenue
Date:Monday, February 6, 2023 1:17:54 PM
Dear Commissioners,
My name is Olivia Cullen and I am resident of 140 Acacia Avenue, Carlsbad, CA.
I'm writing to voice my enthusiastic support for a roundabout at the intersection of
Carlsbad Blvd. and Tamarack Ave. Roundabouts are proven to reduce serious or
fatal crashes by up to eighty percent. Traffic safety is an emergency in Carlsbad, and
we have no excuse not to choose the safest option.
Moreover, this option creates more space for wide sidewalks and bike lanes, which
will make this section of the Carlsbad coast a welcoming space for everyone, ratherthan just a throughway for high-speed traffic.
I strongly encourage the Traffic and Mobility Commission to support this option.
Sincerely,
Olivia Cullen

Subject:Roundabout at Tamarack and Carlsbad Blvd.
Date:Monday, February 6, 2023 12:17:01 PM
Hi There,
I had planned to be at the Traffic & Mobility Commission meeting tonight to register my concerns about the
proposed roundabout at Tamarack and Carlsbad Blvd. Unfortunately, I’m unable to do so. I called the City this
morning in hopes of speaking with someone directly and was asked to write an email to this address instead.
My family and I live on Carlsbad Boulevard. We are in favor of the more standard two lanes in both directions
option and opposed to the traffic roundabout. Our opposition to the roundabout takes two forms - both micro
(impact to us personally as residents on the street with two teenagers) and macro (safety, traffic flow, traffic volume,
quality of life for all).
Would it be possible for a staff member to call me? I’d like to hear what you’re thinking and share my specific
concerns with you.
My name is Polly Williams and I live in Carlsbad. My family has owned this home since 1972 and I have lived here
full time since 2015. It is hard enough to get in and out of our driveway at peak hours under current conditions; a
roundabout would make it nearly impossible.
Thank you,
Polly

Subject:Comments on Carlsbad Blvd. Tamarac Proposals
Date:Monday, February 6, 2023 10:01:15 AM
I have reviewed Proposal #1 and # 2, and to me it is clear that Proposal #1 is superior
and safer than Proposal #2. As an avid bicycle rider who frequently rides on
Carlsbad Boulevard, safety is a paramount concern. Below are my reasons.
Proposal #1 has a clearly marked dedicated bike lane along the side of Carlsbad
Boulevard road and going thru the Tamarac intersection. Cyclists do not have to
leave the bike lane and merge with traffic, which is very dangerous. If you need to improve the visibility and safety of the existing bike lane then do so.
Proposal #1 has a traffic light to slow down (yellow light) and stop all traffic
completely. This gives drivers, cyclists and pedestrians an opportunity to stop, check their surroundings and proceed more safely. There isn't a constant flow of cars and
bicyclists trying to safely navigate the Roundabout. You currently have a speed limit
in this area, so review that, modify if necessary, and then enforce it.
Proposal # 2 has bicycles MERGING with traffic and trying to safely navigate the
Roundabout with cars. This is incredibly dangerous (ask any cyclist). I avoid the
Roundabout at the north end of Carlsbad because it is so dangerous to navigate on a
bicycle. Drivers rarely stop, cut in front of you, are reluctant to let you merge, see bicyclists as an annoyance, tailgate you, and want to zip through the Roundabout as
quickly as possible. Drivers and bicyclists have to continuously look in all directions
for cars, bicyclists and pedestrians in or near the Roundabout, entering the
Roundabout, leaving the Roundabout or going full circle in the Roundabout. The fact is that NOBODY seems to know who has the Right-of-Way in a Roundabout. All
vehicles are constantly moving which is dangerous.
Your rendering for Proposal #2 has a guy in a wheelchair trying to scurry across the Roundabout with traffic coming in both directions, which is ridiculous. If this
handicapped person had a red light which stopped traffic, he wouldn't have to scurry
through a constant flow of traffic and put his life in the hands of hopefully considerate
drivers. Do you really think this Proposal will prevent collisions and save lives?
I truly hope that you will make the right decision and choose Proposal #1.
Thank you.
Sincerely,
Thomas Lane

First, we applaud this city's recent efforts to improve traffic safety for all.
My spouse and I have been residents since 1984 and are avid cyclists. We are strongly against
traffic circles especially at this busy intersection.
A road diet along with improved bike lines are the simplest and safest option. And of course , continued traffic enforcement by our outstanding police officers.
My wife refuses to ride in Encinitas due to the hardscape / bollard hazards. She also will not
ride to Oceanside due to the traffic circle north of Army Navy Academy. Needlessly merging bikes as well as vehicles into one lane is not the best solution when you have a safer option.
When faced with 2 options, most times the simplest solution is the better choice.
Grateful Carlsbad Residents,
David and Maren Fitzgibbons

Subject:Speed limit on Carlsbad Blvd
Date:Friday, February 3, 2023 12:50:33 PM
Since the plan is to make Carlsbad Blvd southbound one driving lane up to Island
Way my suggestion is the the speed limit be 35 until Island Way. There is so much
foot traffic on the road up to Island Way that it would be much safer if the 35 MPH
limit were to be maintained. Right now it shifts to 50 MPH at the light by the Hilton
Garden INN.
