Executive Summary
Earlier this year, the City of Carlsbad asked the public to share their priorities for a 3-mile
stretch of Carlsbad Boulevard from Manzano Drive to La Costa Avenue, including the road itself
and the public land that could be freed up if the road were reconfigured.
Along south Carlsbad Boulevard, the city is working on the South Carlsbad Boulevard Climate
Adaptation Project, a grant-funded project focused on how to maximize the roadway’s
resiliency to coastal flooding and cliff erosion in a 1-mile stretch from Manzano Drive to 400
feet south of Island Way (Figure 1).
9/30/2022 Item 2 2 of 9
Figure 1. South Carlsbad Boulevard Project Area
Near Palomar Airport Road and Las Encinas Creek, southbound Carlsbad Boulevard is currently
exposed to bluff erosion hazards. Periodic flooding of the southbound lanes is already
occurring, resulting in beach cobble on the roadway surface and lane closures.
One end product of the study will be a conceptual design of how southbound Carlsbad
Boulevard from Manzano Drive to Island Way could be moved to the east. Due to the
requirements of the grant at this stage, the project team focused on changes to the roadway,
not the land that could be repurposed because of moving the road to the east.
Using community input, the city’s General Plan which includes several guiding principles for
south Carlsbad Boulevard, and findings of the grant’s studies, three preliminary roadway
designs have been developed that protect public infrastructure from future sea level rise while
prioritizing walking and biking paths. The preliminary roadway designs are meant to explore
viability of relocating South Carlsbad Boulevard through a climate adaptation lens; these are
not intended to be final designs.
Staff presented a project update to the Traffic & Mobility Commission on July 5, 2022, when
some commissioners expressed the need for additional traffic data. In addition, some
stakeholders expressed concern that more time was needed to evaluate the options before
selecting a preferred one.
While funding for the grant expires Feb. 28, 2023, staff are pursuing a grant extension to allow
more time for staff to work with the community, conduct a traffic study, and address issues and
impacts of the options.
Discussion
9/30/2022 Item 2 3 of 9
South Carlsbad Boulevard has a history of erosion and instability near Las Encinas Creek. The
city has closed this section of the roadway, including at Las Encinas Bridge during coastal
storms, resulting in a loss of access for emergency services, residents, businesses, and
recreational visitors. In response to flooding, rock barricades were extended twice under an
emergency permit approved by the California Coastal Commission. Most recently in 2016, rock
shoreline protection was placed during wave events that led to partial closure of the roadway
and emergency repair work.
Since Carlsbad Boulevard is used for coastal access, north-south travel for drivers, cyclists, and
pedestrians, and due to the history of closures related to climate impacts, the city applied for a
State Coastal Conservancy grant to explore options related to moving the roadway.
The grant-funded project’s scope of work includes:
•A cliff erosion assessment (Exhibit 1) to inform the other deliverables for this project.
•A restoration analysis of Las Encinas Creek, which will explore phased adaptation
options for the existing bridge, roadway, and revetment at the Creek, including habitat
restoration options for the area. A draft of the analysis is included in Exhibit 2, and a
final version is expected soon.
•Development of conceptual designs and options that incorporate resiliency to coastal
flooding, cliff erosion, and other sea level rise impacts (discussed later in this staff
report).
While funding for the grant expires on Feb. 28, 2023, staff are pursuing a grant extension to
allow more time for staff to work with the community and address issues and impacts of the
proposed options. Staff will also initiate data collection and work on a traffic study to present to
the Traffic & Mobility Commission with an options analysis when completed.
Community priorities
In early 2022, the City of Carlsbad gathered input from the community about their priorities,
needs, and values related to the future use of the entirety of south Carlsbad Boulevard
(extending beyond the segment being analyzed in the grant-funded project), within the
parameters of the city’s General Plan.
The public input report, shown in Exhibit 3, summarizes the key themes and feedback received
from this outreach.
When it comes to the roadway, some of the priorities shared by the community included:
•Safer bike lanes, including some separated from the flow of car traffic
•Safe, wide walking paths
•Less noise and air pollution from traffic when enjoying the coast
•Slowing down traffic along the coast
•Making it safer to cross the road to get to the coast
•Maintaining ocean views for drivers and residents who live along Carlsbad Boulevard
9/30/2022 Item 2 4 of 9
The Coastal Conservancy grant project was able to use the community’s input in designing
three road options for the 1-mile stretch from Manzano Drive to Island Way.
Decisions already made
The city’s General Plan includes guiding principles for south Carlsbad Boulevard, and the
mobility element further defines Carlsbad Boulevard as a “coastal street.” With these existing
policy statements, community members were asked to share their values, needs and priorities.
The City of Carlsbad’s General Plan includes several guiding principles for south Carlsbad
Boulevard:
•Carlsbad Boulevard shall become more than a road. This transportation corridor shall
provide for recreational, aesthetic and community gathering opportunities that equal
the remarkable character of the land.
•Community safety shall be a high priority. Create destination that provides a safe public
environment to recreate.
•Strategic public access and parking is a key to success. Development shall capitalize on
opportunities to add/enhance multiple public access points and public parking for the
beach and related recreational amenities.
•Open views are desirable and important to maintaining the character of the area.
Preservation and enhancement of views of ocean, lagoons, and other water bodies and
beaches shall be a high priority in road, landscaping, and amenity design and
development.
•Enhance the area’s vitality through diversity of recreational land uses. Carlsbad
Boulevard development shall provide for amenities, services, and goods that attract a
diversity of residents and visitors.
•Create vibrant and sustainable public spaces. Development shall provide for unique and
vibrant coastal gathering spaces where people of all age groups and interests can gather
to enjoy recreational and environmental amenities and supporting commercial uses.
•Connect community, place and spirit. Design shall complement and enhance
connectivity between existing community and regional land uses.
•Environmentally sensitive design is a key objective. Environmentally sensitive
development that respects coastal resources is of utmost importance.
•A signature scenic corridor shall be created through design that honors the coastline’s
natural beauty. The resulting improvements will capture the ‘essence’ of Carlsbad;
making it a special place for people from throughout the region with its natural beauty
and vibrant public spaces. Properly carried out, the realigned boulevard will maximize
public views and encourage everyone to slow down and enjoy the scenery.
•Reimagining of Carlsbad Boulevard should be visionary. The reimagined Carlsbad
Boulevard corridor will incorporate core community values articulated in the Carlsbad
Community Vision by providing:
1.Physical connectivity through multi-modal mobility improvements including
bikeways, pedestrian trails, and a traffic-calmed street;
9/30/2022 Item 2 5 of 9
2.Social connectivity through creation of memorable public spaces; and
3.Economic vitality through a combination of visitor and local-serving commercial,
civic, and recreational uses and services.
The city’s General Plan includes policies on how different types of streets are designed.
Carlsbad Boulevard falls under the category of coastal streets, which calls for the following
design elements:
•Primary purpose is to move people along the city’s ocean waterfront and connect
people to the beach, recreation, businesses, and residences in close proximity to the
waterfront. The street serves as a destination for people who drive, walk and bicycle
along the ocean waterfront.
•Designed to safely move all modes of travel while enhancing mobility for pedestrians
and bicyclists.
•Vehicle speeds shall be managed to support uses along the coast.
•Enhanced bicycle and pedestrian crossings should be provided, including: -High visibility
crosswalks – Enhanced pedestrian notifications (e.g., responsive push-button devices) –
Enhanced bicycle detection – Bicycle lanes shall be provided and can be further
enhanced or complemented by other facilities (such as bicycle lane buffers or off-street
pathways).
•Pedestrian facilities should be a minimum of five feet and shall strive for six to eight feet
in width and shall conform to ADA requirements.
•Pedestrian crossing distances should be minimized.
•Trail facilities should be encouraged.
•Opportunities for mid-block pedestrian crossings should be investigated.
•On-street parking should be provided.
•Transit facility and operation improvements should be encouraged.
Existing conditions
In its current configuration, Carlsbad Boulevard within the project area operates as a four-
vehicle lane section, with two vehicle lanes in each direction and is split by a large, landscaped
median. Both northbound and southbound directions have buffered bike lanes. Sidewalks are
provided sparsely throughout the project area near Island Way and Solamar Drive.
Carlsbad Boulevard is classified as a Coastal Street, meaning its primary purpose is to move
people along the city’s ocean waterfront and connect people to the beach, recreation,
businesses, and residences in close proximity to the waterfront.
Counts were collected as a part of the Carlsbad Active Transportation Monitoring program in
September 2021 along Carlsbad Boulevard between Avenida Encinas and Ponto Road. This
included 24-hour vehicular counts, 13-hour pedestrian counts and 13-hour bicycle counts. The
counts are summarized below:
•Weekday Vehicular Count: 10,833 vehicles
•Weekend Vehicular Count: 14,069 vehicles
9/30/2022 Item 2 6 of 9
•Weekday Bicycle Count: 797 bikes
•Weekend Bicycle Count: 2,509 bikes
•Weekday Pedestrian Count: 147 pedestrians
•Weekend Pedestrian Count: 408 pedestrians
As shown by these counts, this section of Carlsbad Boulevard not only moves vehicular traffic,
but also high volumes of pedestrians and bikes. As noted within the Carlsbad Active
Transportation Monitoring report, this section saw the largest weekend bike count and the
second largest weekday bike count out of all 26 study segments throughout Carlsbad.
Roadway options
Due to the requirements of the grant at this stage, the project team focused on changes to the
roadway, not the land that could be repurposed as a result of moving the road to the east. The
three options include:
•4-lane road with traffic signals
•2-lane road with roundabouts
•2-lane road with roundabouts and one enhanced pedestrian crossing
The preliminary conceptual design options are provided in Exhibit 4. All three options show a
majority of the Class-I and pedestrian pathway within the depicted coastal hazard zone and
along the existing southbound lanes of Carlsbad Boulevard. The Class-1 facility is a shared
pathway for exclusive use by pedestrians, bicyclists, and other non-motorized modes of travel
including strollers and skateboards. The Class-I path will be intended for use by slower moving
users with a maximum speed of 20 mph.
This is a cost-effective approach to achieve the planned separated bike and pedestrian
pathways, although, this alignment is only viable as long as the area is available for use. There
may be several iterations of Class-I and pedestrian pathway alignments as the coastline erodes
and changes in the future. The final deliverables for this project will include information on how
to “phase” the adaptation of all infrastructure in the coastal hazard zone, including this Class I
pathway, likely based on the frequency and intensity of climate impacts experienced in the
project area.
Staff presented a project update to the Traffic & Mobility Commission on July 5, 2022; a
summary of the comments and questions received at the meeting are included in Exhibit 6.
Staff also presented a project update to the Parks & Recreation Commission on July 18, 2022,
and the Planning Commission on August 17, 2022 and will be presenting to the Traffic &
Mobility Commission on August 18, 2022.
While the project’s scope includes preliminary options for roadway realignment that include
multi-use pathway as seen in Options 1-3, additional funding would be needed to further refine
and design any public access and recreational amenities. A memo capturing the public input
9/30/2022 Item 2 7 of 9
received and other analysis prepared, as well as a list of concepts for these amenities for
further consideration, will be prepared as a deliverable for the project.
Fiscal Analysis
No city funding is being requested at this time.
Next Steps
•Staff will continue to work with the State Coastal Conservancy to pursue a grant
extension beyond Feb. 28, 2023.
•Public input will be shared with the City Council on Sept. 13, 2022 to receive input on
the preliminary design options.
•Staff will continue to work with community groups affected by the design of the
preliminary roadway options to address concerns.
•A primary final deliverable for this project will be a conceptual design of how
southbound Carlsbad Boulevard from Manzano Drive to Island Way could be moved to
the east in order to adapt to climate change impacts and fulfill requirements for a
California Coastal Commission permit extension.
•The grant does not include funding to conduct environmental analysis, a detailed traffic
or roadway analysis, or to build the new road, just to complete a 30% design centered
around climate adaptation.
•Other final deliverables include the final Las Encinas Creek restoration analysis, a final
design report, and a long-term master plan that discusses phased adaptation over time.
•Beyond completing the grant-funded project, the City Council will provide direction on
next steps for the 1-mile section of roadway, Las Encinas Creek habitat restoration and
phased adaptation, and the full length of south Carlsbad Boulevard.
•At this time, no additional work has been included in the city’s FY 2022-23 budget for
either project.
Environmental Evaluation (CEQA)
The California Environmental Quality Act (“CEQA”) and its implementing regulations (“CEQA
Guidelines”) adopted by the Secretary of the California Natural Resources Agency, list classes of
projects that have been determined not to have a significant effect on the environment and as
a result are exempt from further environmental review under CEQA. The City Planner has
determined that this report is statutorily exempt from the requirements of CEQA pursuant to
CEQA Guidelines sections 15262, Feasibility and Planning Studies; and 15378(b)(5), which
exempts organizational or administrative activities of governments that will not result in direct
or indirect physical changes in the environment. This organizational and administrative activity
relates to the ongoing study of preparing an adaptation plan for a portion of a roadway
segment in the city (South Carlsbad Coastline Project). This general direction does not have a
legally binding effect on any possible future discretionary action. Public input received and
technical information prepared during the planning process will be utilized in preparing a future
environmental review document to support the South Carlsbad Boulevard Coastline Project.
