Executive Summary
Addendum No. 1 Housing Element Implementation and Public Safety Element Update SEIR iii
Executive Summary
The Project consists of an update to the City of Carlsbad’s Climate Action Plan (CAP Update). The city’s
CAP Update outlines goals, strategies, and actions for reducing emissions and combating climate
change. The current CAP, approved as part of the 2015 General Plan and amended in July 2020,
ensures that Carlsbad does its part to contribute to the goals of AB 32 and its successor legislation, SB
32, to reduce its GHG emissions to 1990 levels by 2020, and to 40 percent below 1990 by 2030. The
horizon year for the current CAP is 2035, corresponding with the buildout year of the 2015 General
Plan.
The CAP Update contains strategies to reduce local greenhouse gas (GHG) emissions and streamline
environmental review of future development projects in the city in accordance with the California
Environmental Quality Act (CEQA) such that new development is designed and built following
sustainable practices. This is the city’s second comprehensive update to the CAP, following the CAP
Amendment No. 1 in July 2020 and the original CAP which was adopted in September 2015. CAP
strategies reflect the goals and policies of the city’s General Plan, addressing topics such as increasing
energy efficiency, expanding bicycle and pedestrian infrastructure, and achieving solid waste reduction.
The CAP Update establishes measures and actions to assist the City of Carlsbad in achieving its GHG
emission reduction targets. The CAP Update includes measures organized into six sectors: water and
wastewater, energy, waste diversion, transportation, off-road equipment, and carbon sequestration.
These sectors serve as a way to organize GHG reduction measures and indicate the focus areas of the
associated measures. Within each measure there are one or more actions that define activities, programs,
policies, or projects that the city government will implement or support to achieve CAP Update goals.
In considering the potential environmental impacts of the CAP Update, the city has determined that the
EIR certified for the 2015 General Plan update (General Plan & Climate Action Plan Environmental
Impact Report, State Clearinghouse Number 2011011004, dated June 2015) and SEIR certified for the
2023 Housing Element Implementation and Public Safety Element Update (Housing Element
Implementation and Public Safety Element Update Supplemental Environmental Impact Report, State
Clearinghouse Number 2022090339, dated July 2023) are of continuing informational value. Further,
the city has determined that the potential environmental impacts (both direct and indirect impacts)
of the CAP Update are within the scope of the previously certified CEQA documents, and that none of
the conditions requiring subsequent or supplemental environmental review under CEQA Guidelines
section 15162 exists. Based on the information and analysis provided below, the city has determined
that only minor or technical changes to the previously certified EIRs are necessary and that preparation
of an Addendum pursuant to CEQA Guidelines section 15164 is appropriate. This Addendum was
prepared as a first-tier CEQA document to “adequately address” the direct and indirect physical
environmental effects of CAP Update implementation, including implementation ordinances, so the
city can focus analysis in second-tier documents and implementation actions on issues specific to later
projects. Agencies can adopt General Plan or zoning policies, and apply those policies to specific
projects that are consistent with the General Plan or zoning ordinance (Public Resources Code section
21083.3). Under such circumstances, if an impact is not peculiar to the project, then issues addressed
by those policies are statutorily exempt from further CEQA review. Based on the general nature of its
measures and actions, the CAP Update is analyzed herein to determine whether it could cause a direct
or reasonably foreseeable indirect change in the environment.

Introduction and Project Summary
Addendum No. 1 Housing Element Implementation and Public Safety Element Update SEIR 3
Project Description
The City of Carlsbad (City) strives to reduce its contribution to climate change through policy
frameworks that pursue the community’s goal of promoting a sustainable environment. The Climate
Action Plan Update (CAP Update) serves to continue and elevate this policy framework by realigning
its climate action policies with the most recent technological advancements, best practices, and State
legislation. The CAP Update is organized into the following chapters:
• Chapter 1, Introduction. The introduction provides an overview of the effects of global
climate change, describes the extensive and targeted outreach to engage community
members to ensure that the planning process is inclusive and representative of various needs
and viewpoints, and provides background for the city’s climate action planning process.
• Chapter 2, Greenhouse Gas Emissions Inventory, Forecasts, and Targets. This chapter
inventories the city’s GHG emissions to demonstrate the city’s overall contribution to climate
change and the contribution of individual GHG emissions sources and forecasts how
emissions are expected to change with future growth. This chapter presents the technical
basis for the CAP Update, and sets Carlsbad-specific GHG reduction targets for 2035 and
2045 that align with State legislation.
• Chapter 3, Greenhouse Gas Reduction Strategies and Measures. This chapter presents six
strategies and 25 measures that will reduce GHG emissions and build resilience to climate
impacts in the community (i.e., GHG reduction strategies). The strategies are organized into
six sectors: water and wastewater, energy, waste diversion, transportation, off-road
equipment, and carbon sequestration.
• Chapter 4, Implementation and Monitoring. Building off the information in Chapter 3, this
chapter outlines the process by which the city will implement CAP Update strategies and
measures, and how progress will be monitored over time to ensure the CAP Update is
effective in reducing emissions.
The CAP Update contains strategies to reduce local greenhouse gas (GHG) emissions and streamline
environmental review of future development projects in the city in accordance with the California
Environmental Quality Act (CEQA) such that new development is designed and built following
sustainable practices. The CAP Update is the city’s second comprehensive update to the CAP, following
the CAP Amendment No. 1 in July 2020 and the original CAP adopted in September 2015 as part of the
2015 General Plan. CAP strategies reflect the goals and policies of the city’s General Plan, addressing
topics such as increasing energy efficiency, expanding bicycle and pedestrian infrastructure, and
achieving solid waste reduction.
The CAP Update establishes measures and actions that would reduce GHG emissions in Carlsbad to
levels that achieve its GHG reduction targets, which are aligned with the State’s GHG reduction goals.
The city’s 2035 target requires GHG emissions to be reduced 50 percent below 2016 levels (aligned
with and extrapolated from SB 32) and reduced to 85 percent below 2016 levels by 2045 (aligned with
AB 1279). The CAP Update measures and actions are identified in Table 1. The measures and actions
meet the city’s GHG reduction targets.
The CAP Update meets the requirements for a qualified plan for the reduction of greenhouse gas
emissions under State CEQA Guidelines Section 15183. for use in cumulative impact analysis pertaining
to development projects. This Addendum No. 1 is intended to be used for future project-specific GHG
emissions analyses by providing the appropriate level of environmental review to allow for future
projects to tier from and streamline their analysis of GHG emissions pursuant to CEQA Guidelines

Section 15183.5(b)(2), unless otherwise determined to be cumulatively considerable. CEQA provides
a variety of devices available to streamline the environmental review process and avoid redundancy.
This Addendum No. 1 was also prepared to function as a first-tier CEQA document that would
“adequately address” the direct and indirect physical environmental effects of GHG reduction
measures including implementation ordinances so that city can focus the analysis in its second-tier
documents and implementation actions solely on the issues specific to the later project. Pursuant to
Public Resources Code section 21083.3, agencies can adopt General Plan or zoning policies, and apply
those policies to specific projects that are consistent with the General Plan or zoning ordinance. Under
such circumstances, if the impact at issue is not peculiar to the parcel or project, then the particular
issues addressed by those policies are statutorily exempt from further CEQA review. Based on the
“general nature” of the proposed measures and actions, the CAP Update is analyzed herein as to
determine whether the activity could cause a direct or reasonably foreseeable indirect change in the
environment.

Note: The implementation actions under each GHG reduction measure have been categorized as “Primary” or
“Supportive” to signify the degree in which an action affects the quantifiable GHG reductions that are expected
to be achieved with implementation. Primary actions are implementation actions that drive quantifiable GHG
reductions. Supportive actions provide additional support to the successful implementation of the measure and
may also have associated GHG reductions that have not been quantified as part of the CAP Update.
The city has developed an update to its Climate Action Plan Consistency Review Checklist (CAP
Oct. 2, 2024 Item #1 34 of 157
Introduction and Project Summary
Addendum No. 1 Housing Element Implementation and Public Safety Element Update SEIR 11
Consistency Checklist), in conjunction with the CAP Update, to provide a streamlined review process
for proposed new development projects that are subject to discretionary review and trigger
environmental review pursuant to CEQA. New developments that are consistent with growth
projections and applicable GHG reduction measures of the CAP Update are eligible for streamlining
under State CEQA Guidelines Section 15183.5. The proposed CAP Consistency Checklist is discussed in
more detail in Chapter 4 of the CAP update.
The CAP Update includes strategies, measures, and actions intended to reduce GHG emissions from
six emissions sectors. To achieve reductions in GHG emissions, measures and actions within each
sector are proposed to be implemented within specific timeframes. The strategies, measures, and
actions are listed in full in Table 1. The strategies, measures, and actions describe the overall approach
and detail the specific programs and actions that the city will carry out. This Addendum has been
prepared to address the implementation of the CAP Update measures and actions that could result in
reasonably foreseeable physical impacts to the environment. More focused CEQA analysis (focusing
on specifics of individual implementing actions) may be required in the future.
Discretionary Actions
The CAP Update would require the following discretionary actions by the City Council:
• Approval of Addendum No. 1 to the Housing Element Implementation and Public Safety
Element Update Supplemental Environmental Impact Report
• Adoption of the CAP Update

Project Context
Addendum No. 1 Housing Element Implementation and Public Safety Element Update SEIR 13
2 Project Context
The following provides a history and timeline of the environmental documentation that has been
prepared for the City of Carlsbad’s CAP and Housing Element Implementation and Public Safety
Element Update.
On September 22, 2015, the City of Carlsbad certified a final environmental impact report (EIR) for a
comprehensive update to the General Plan and a Climate Action Plan (General Plan & Climate Action
Plan Environmental Impact Report, State Clearinghouse Number 2011011004, dated June 2015) (City
of Carlsbad 2015). The city’s 2015 CAP was developed in response to AB 32, and the increasing severity
of climate events. The 2015 CAP includes goals, policies, and actions for Carlsbad to reduce GHG
emissions and address climate change through 2035. The certified EIR discussed the potential
environmental impacts (both direct and indirect impacts) associated with future development allowed
under the General Plan update and included a thorough analysis of the estimated build out of the city
through the horizon year 2035. The EIR found that, with implementation of the policies and programs
contained in the General Plan and recommended mitigation measures, all impacts (direct and indirect)
associated with future development under the General Plan update would be less than significant,
except impacts on Air Quality and Transportation which would be significant and unavoidable.
As statewide targets adjusted to limit global warming below 2 degrees Celsius, the city has adapted its
CAP and GHG reduction targets accordingly. On July 14, 2020, the City Council approved CAP
Amendment No. 1 to revise the GHG inventory and reduction targets and forecast, update reductions
from existing measures and incorporate community choice energy as a new reduction measure. This
was partially influenced by the publication of the 2017 California Air Resources Board (CARB) Climate
Change Scoping Plan (Scoping Plan) and the 2018 San Diego Association of Governments (SANDAG)
Regional Climate Action Planning Framework (ReCAP). Both documents included new guidance on
calculating GHG reduction targets. The amended CAP contained a 2012 GHG inventory, requiring the
recalculation of 2020 and 2035 emissions reduction targets and recalculation of the business-as-usual
(BAU) forecast, State and federal emissions reductions, and local reductions needed to reach a 2017
Scoping Plan aligned target. The BAU forecast assumes no additional actions to reduce GHG emissions
occur after 2012 (the updated baseline inventory year), providing an assessment of how Carlsbad’s
GHG emissions would change with future growth.
Addendum No. 1 to the 2015 General Plan Update and CAP EIR was prepared in May 2020 for updates
to the certified CAP (“CAP Amendment No. 1”) (City of Carlsbad 2020). CAP Amendment No. 1 included
use of the 2012 GHG inventory, calculation of 2020 and 2035 targets using the 2012 GHG inventory and
guidance from CARB’s 2017 Climate Change Scoping Plan, the addition of Community Choice Energy
(CCE) as a GHG reduction measure and recalculation of the CAP measures to reflect changes in State
and federal policies and the changed electrical generation emissions factor associated with CCE. The
Addendum concluded that CAP Amendment No. 1 did not constitute a substantial change in the project
or circumstances involving significant environmental effects or a substantial increase in the severity of
previously identified effects. The mitigation measures previously included and remaining in the CAP,
and the CCE implementation measure remained feasible. Therefore, CAP Amendment No. 1 did not
necessitate a subsequent EIR because it did not create any of the situations contained in State CEQA
Guidelines Section 15162.

City of Carlsbad
Climate Action Plan Update
14 Addendum
The Housing Element Update for the General Plan was prepared in late 2020 and provided to the
California Department of Housing and Community Development (HCD) for preliminary review. The
Housing Element was analyzed under its own respective CEQA document, Addendum No. 2 to the
2015 General Plan EIR, which was approved by the City Council on April 6, 2021 (SCH#2011011004)
(City of Carlsbad 2021). This Addendum found that, with implementation of mitigation measures, all
impacts (direct and indirect) associated with the Housing Element did not identify any changes in the
Project (2015 General Plan), changes in circumstance, and/or any new information of substantial
importance that would cause significant effects to environmental resources. Addendum No. 2
determined that the 2015 General Plan EIR was of continuing informational value, the changes in the
2021 Housing Element Update were within the scope of that previously certified EIR, and none of the
conditions requiring the preparation of subsequent or supplemental environmental review under
CEQA Guidelines section 15162 existed.
On February 2, 2024, the City of Carlsbad certified a supplemental environmental impact report (SEIR)
which consists of amendments to the Carlsbad General Plan, including the Land Use and Community
Design Element and Public Safety Element, and amendments to Carlsbad Municipal Code Title 21, the
Zoning Ordinance (Housing Element Implementation and Public Safety Element Update Supplemental
Environmental Impact Report, State Clearinghouse Number 2022090339, dated July 2023) (City of
Carlsbad 2024). The certified SEIR discussed the potential environmental impacts (both direct and
indirect impacts) associated with the development of housing on 18 sites as part of the Housing Element
implementation. The SEIR identified updates to the Carlsbad General Plan, specifically the Land Use and
Community Design Element, to allow for this development. The Public Safety Element would also be
updated to ensure consistency with State regulations. Updates to the Land Use and Community Design
Element included the addition of two new residential land use designations (R-35 and R-40) for the
accommodation of higher density residential development, establishment of revised minimum
densities for some residential designations, miscellaneous, related changes to tables, text and policies,
and changes to land use designations on multiple sites to accommodate the city’s Regional Housing
Needs Allocation (RHNA) share. Updates to the Public Safety Element included the addition of the
requirements of new State legislation and the incorporation of new policies based on local and regional
data. The SEIR found that, with implementation of mitigation measures, all impacts (direct and indirect)
associated with the Housing Element Implementation and Public Safety Element Update would be less
than significant, except impacts on Air Quality, GHG, Noise, and Transportation which would be
significant and unavoidable.
In considering the potential environmental impacts of the CAP Update, the city has determined that
the EIR certified for the 2015 General Plan update and SEIR certified for the 2024 Housing Element
Implementation and Public Safety Element Update are of continuing informational value. The city also
has determined that the potential environmental impacts (both direct and indirect impacts) of the CAP
Update are within the scope of the previously certified EIR and SEIR and that none of the conditions
requiring subsequent or supplemental environmental review under CEQA Guidelines section 15162
exists. Based on the information and analysis provided below, the city has determined that only minor
or technical changes to the previously certified EIR are necessary and that that preparation of an
Addendum pursuant to CEQA Guidelines section 15164 is appropriate.
Oct. 2, 2024 Item #1 38 of 157
Overview of the CEQA Guidelines
Addendum No. 1 Housing Element Implementation and Public Safety Element Update SEIR 15
3 Overview of the CEQA Guidelines
Section 15160 of the CEQA Guidelines explains that there are several mechanisms, and variations in
environmental documents, that can be tailored to different situations and intended uses of
environmental review. Specifically, Section 15160 states that the “…variations listed [including
Subsequent EIRs, Supplemental EIRs, and Addendums] are not exclusive. Lead agencies may use other
variations consistent with the Guidelines to meet the needs of other circumstances.” This provision
allows Lead agencies to tailor the use of CEQA mechanisms (such as this Addendum) to fit the
circumstances presented to the Lead agency by a project. Here, the city has opted to prepare an
Addendum to assess the minor modifications of the Project that have transpired since preparation of
the EIR.
Public Resources Code Section 21166 and California Environmental Quality Act (CEQA) Guidelines
Sections 15162 and 15164 set forth the criteria for determining the appropriate additional
environmental documentation, if any, to be completed when changes are proposed to a project that
has a previously certified Environmental Impact Report (EIR). When considering the need for
additional environmental review, the fundamental determination a lead agency must make is whether
the previously certified EIR retains some informational value or whether changes in the project or
circumstances have rendered it wholly irrelevant. If the previously certified EIR has continuing
informational value, the lead agency then must determine whether the proposed changes in the
Project require additional environmental review under Public Resources Code Section 21166 and
CEQA Guidelines Section 15162.
CEQA Guidelines Section 15164 states that a lead agency shall prepare an addendum to a previously
certified EIR if some changes or additions are necessary, but none of the conditions described in
Section 15162 calling for preparation of a subsequent EIR have occurred. CEQA Guidelines section
15162(a) states that no Subsequent or Supplemental EIR shall be prepared for a project with a certified
EIR unless the lead agency determines, based on substantial evidence in the light of the whole record,
one or more of the following:
1. Substantial changes are proposed in the project that will require major revisions of the previous
EIR due to the involvement of new significant environmental effects or a substantial increase in
the severity of previously identified significant effects.
2. Substantial changes occur with respect to the circumstances under which the project is
undertaken which will require major revisions of the previous EIR due to the involvement of new
significant environmental effects or a substantial increase in the severity of previously identified
significant effects.
3. New information of substantial importance, which was not known and could not have been
known with the exercise of reasonable diligence at the time the previous EIR was certified as
complete, shows any of the following:
A. The project will have one or more significant effects not discussed in the previous EIR.
B. Significant effects previously examined will be substantially more severe than shown in the
previous EIR.
C. Mitigation measures or alternatives previously found not to be feasible would in fact be
feasible and would substantially reduce one or more significant effects of the project, but the
project proponents decline to adopt the mitigation measure or alternative.

Climate Action Plan Update
16 Addendum
D. Mitigation measures or alternatives that are considerably different from those analyzed in
the previous EIR would substantially reduce one or more significant effects on the
environment, but the project proponents decline to adopt the mitigation measure or
alternative.
The analysis pursuant to Section 15162 demonstrates whether the lead agency can approve the activity
as being within the scope of the existing certified EIR, that an addendum to the existing EIR would be
appropriate, and no new environmental document, such as a new EIR, would be required. The addendum
need not be circulated for public review but can be included in or attached to the final EIR, and the
decision-making body shall consider the addendum with the final EIR prior to deciding on the project.
The City of Carlsbad has prepared this Addendum, pursuant to CEQA Guidelines Sections 15162 and
15164, to evaluate whether the Project’s environmental impacts are covered by and within the scope
of the Housing Element Implementation and Public Safety Element Update Supplemental
Environmental Impact Report (State Clearinghouse Number 2022090339, dated July 2023). The
following Addendum details any changes in the Project, changes in circumstances under which the
Project is undertaken, and/or “new information of substantial importance” that may cause one or
more significant effects to environmental resources.
The responses herein substantiate and support the City of Carlsbad’s determination that the potential
environmental impacts of the CAP Update measures and actions are within the scope of the Housing
Element Implementation and Public Safety Element Update SEIR, do not require subsequent or
supplemental environmental review under CEQA Guidelines Section 15162 and, in conjunction with
the SEIR, preparation of an Addendum pursuant to CEQA Guidelines Section 15164 is appropriate.

City of Carlsbad
Climate Action Plan Update
18 Addendum
5 Addendum Methodology
The city has previously prepared and certified an EIR for the 2015 General Plan, an Addendum for the
CAP Amendment (2020), an Addendum for the Housing Element (2021), and a SEIR for the Housing
Element Implementation and Public Safety Element Update (2024). Collectively, these CEQA reviews
are known as the “Previous CEQA Documents.” No legal actions were filed challenging the Previous
CEQA Documents and thus are presumed valid.
Since the adoption of the Previous CEQA Documents, there have been no substantial changes in the
city’s policies that relate to actions in the CAP Update; neither has there been new information, or a
change of circumstances which would invalidate the Previous CEQA Documents. In addition, the city
adopted ordinances in 2019 that amended the Carlsbad Municipal Code related to energy efficiency,
renewable energy, alternative water heating, electric vehicle charging infrastructure and
transportation demand management, which further mitigate environmental impacts.
The CAP Update is a programmatic planning document which catalogues the priorities of the city for
reducing energy use and greenhouse gas emissions to meet State reduction targets. The CAP Update
does not approve or authorize a project that could potentially alter the environment. Rather, it
outlines the need for future work to advance each of the separate measures and actions.

Addendum Evaluation
Addendum No. 1 Housing Element Implementation and Public Safety Element Update SEIR 21
Previous CEQA Analysis Aesthetics Findings
The 2024 SEIR identified less than significant impacts for scenic vistas (AES-1), scenic resources within
scenic highways (AES-2), visual quality (AES-3), and light and glare (AES-4) (Section 4.1, Aesthetics).
Addendum Analysis
The implementation of the CAP Update measures and actions would result in short-term and long-
term changes related to aesthetics as described below.
Construction activities associated with the implementation of the CAP Update, such as equipment use
and staging of materials, would result in short-term, temporary changes to aesthetic conditions in the
city. The types of construction activities associated with the CAP Update would vary depending on the
type of CAP Update measure. For example, Measures T-1, T-4, T-5, T-8, and T-9 would involve removing
existing pavement; repaving roadway surfaces; painting or restriping pavement; modifying curbs; laying
concrete, and installing traffic signals, lighting, landscaping, street furniture, and other amenities. Some
of these improvements, such as Measure E-3.3, W-1, and W-2, would require limited ground
disturbance. Construction activities would be short-term and temporary, and would not involve
equipment of substantial height, bulk, or massing that would have substantial adverse effects on existing
scenic vistas, scenic resources, or visual quality. Because duration of these activities would be limited to
relatively short periods, their temporary effects on aesthetic resources would not be substantial.
Construction activities would also incrementally increase sources of light and glare in the city, for
example from outdoor lighting sources associated with construction of transportation improvements
and glare from construction vehicles and equipment. Construction activities would generally occur
during daytime hours and would comply with applicable lighting requirements including the City’s
Zoning Ordinance and Title 24 of the California Building Code that reduce light spillover. Furthermore,
construction activities would be located in developed areas with existing sources of outdoor lighting
and glare, characteristic of developed urban and suburban environments. Thus, the CAP Update would
not create temporary new sources of substantial light or glare that would adversely affect day or
nighttime views in the city.
Long-term changes resulting from implementation of CAP Update measures would include
improvements at or near grade level of existing roadways, as well as minor changes to traffic
intersections and walkways (through implementation of Measures T-1, T-4, T-5, T-8, and T-9),
improvements to water and wastewater systems (Measures W-1 and W-2), and planting of trees
(through implementation of Measure CS-1). Energy-related measures such as Measure E.3-3, which
includes the construction of solar carports, would also result in changes to the aesthetic environment.
Implementation of Measures T-1, T-4, T-5, T-8, and T-9 would also result in the installation of new
sidewalks, new and upgraded bikeways and walkways along existing developed roadways and rights-
of-way in the city, and the installation of roundabouts or control traffic within the intersections of
existing developed roadways. The CAP Update would not result in new features of substantial height,
bulk, or massing that would result in substantial long-term damage to scenic vistas, scenic resources,
or visual quality. Additionally, the increase in planted trees and the development of new landscaping
(Measure CS-1) would offer long-term visual improvement to the local surrounding area and would
not result in a substantial effect to scenic vistas, scenic resources, or visual quality.
Transportation measures and actions included in the CAP Update would include improvements to the
city’s existing pedestrian, bicycle, and transit network that may introduce new short term light
sources. In addition, installation of solar carports (Measure E-3.3) would introduce new sources of
glare from sunlight reflecting off of solar photovoltaic panels.

City of Carlsbad
Climate Action Plan Update
22 Addendum
These types of improvements would comply with applicable lighting requirements including the city’s
Zoning Ordinance and Title 24 of the California Building Code that reduce light spillover. Improvements
resulting from implementation of the CAP Update would be located in developed areas with existing
sources of outdoor lighting and glare, characteristic of developed urban and suburban environments.
Thus, the CAP Update would not create new long-term sources of substantial light or glare that would
adversely affect day or nighttime views in the city.
Conclusion
There are no changes in circumstances or new information of substantial importance that would
require major revisions to the 2024 SEIR or result in new significant effects or a substantial increase in
the severity of previously identified effects related to aesthetics. The 2024 SEIR did not identify
significant aesthetic impacts and did not identify mitigation measures. The CAP Update would not
result in any new or substantially more severe significant impacts related to aesthetics. Applicable Mitigation Measures from the SEIR
There are no mitigation measures from the 2024 SEIR identified to reduce impacts related to
aesthetics.

Oct. 2, 2024 Item #1 48 of 157
Addendum Evaluation
Addendum No. 1 Housing Element Implementation and Public Safety Element Update SEIR 25
Previous CEQA Analysis Agriculture and Forestry Resources Findings
The 2024 SEIR identified no impacts for converting Prime Farmland, Unique Farmland, or Farmland of
Statewide Importance (Farmland); for conflicting with existing zoning for agricultural use or a
Williamson Act contract or with existing zoning for, or cause rezoning of, forest land (as defined in
Public Resources Code Section 12220(g)); timberland (as defined by Public Resources Code Section
4526); or timberland zoned Timberland Production (as defined by Government Code Section
51104(g)); and for resulting in the loss of forest land or conversion of forest land to non-forest use; or
involving other changes in the existing environment which, due to their location or nature, could result
in conversion of Farmland to non-agricultural use or conversion of forest land to non-forest use
(Section 4.16.1, Agriculture and Forestry Resources).
Addendum Analysis
Implementation of the CAP Update would not result in the conversion of Important Farmland or forest
land to urban or other uses. Measures and actions included in the CAP Update may include
construction activities, such as equipment use and staging of materials; however, construction
activities would occur in previously disturbed, developed areas not currently used for agricultural uses
or under a Williamson Act contract. There are currently no Williamson Act contracts in the city and the
CAP Update does not propose land use changes that would affect the status of any Williamson Act
contracts (DOC 2024). Additionally, there are no areas in the city zoned as forest or timberland,
therefore, implementation of the CAP Update would not conflict with existing zoning or cause rezoning
any forest land, timberland, or timber land zoned for timberland production. Therefore, the CAP
Update would not involve other changes in the exiting environment which, due to their location or
nature, could result in the conversion of Farmland, to non-agricultural use or conversion of forest land
to non-forest use.
Conclusion
There are no changes in circumstances or new information of substantial importance that would
require major revisions to the 2024 SEIR or result in new significant effects or a substantial increase in
the severity of previously identified effects related to agriculture and forestry resources. The 2024
SEIR did not identify significant agriculture and forestry resources impacts and did not identify
mitigation measures. The CAP Update would not result in any new or substantially more severe
significant impacts related to agriculture and forestry resources. Applicable Mitigation Measures from the SEIR
There are no mitigation measures from the 2024 SEIR identified to reduce impacts related to
agriculture and forestry resources.

Addendum Evaluation
Addendum No. 1 Housing Element Implementation and Public Safety Element Update SEIR 27
Previous CEQA Analysis Air Quality Findings
The 2024 SEIR identified a less than significant impact related to a conflict with or obstruction of the
San Diego Regional Air Quality Strategy or State Implementation Plan (AQ-1) with implementation of
mitigation measure AQ-1. The 2024 SEIR identified that although mitigation measure AQ-2 would
reduce operational emissions from future development, it would be speculative to quantify such
emissions until details of the individual projects are known and concluded impacts to be significant
and unavoidable (AQ-2). The 2024 SEIR identified a less than significant impact related to exposing
offsite sensitive receptors to substantial pollution concentrations (AQ-3) with implementation of
mitigation measure AQ-3 and mitigation measure AQ-4. The 2024 SEIR also identified a less than
significant impact related to creating objectional odors (AQ-4) (Section 4.2, Air Quality).
Addendum Analysis
The implementation of the CAP Update measures and actions would result in short-term and long-
term changes related to air quality as described below.
Construction activities associated with the implementation of the CAP Update, such as equipment use,
construction of new facilities or retrofitting of existing facilities, would result in construction-related
air quality emissions. The types of construction activities associated with the CAP Update would vary
depending on the type of CAP Update measure. Examples of activities that would result from
implementation of the CAP Update measures include construction of new EV charging stations, public
zero emission vehicle and bicycle charging infrastructure, building efficiency retrofits, roundabouts or
traffic circles, new and improved bicycle infrastructure, new solar carports, and water and wastewater
system improvements (e.g., Measures T-1, T-2, T-3, T-4, T-5, T-8, T-9, E-3.3, W-1, and W-2). These
construction activities would involve using construction equipment and vehicles to remove existing
pavement; repave roadway surfaces; paint or restripe pavement; modify curbs; lay concrete, and
install traffic signals, lighting, landscaping, street furniture, and other amenities. These construction
activities would be completed by workers located in the city and surrounding areas in the San Diego
region.
Construction activities resulting from implementation of the CAP Update would generate emissions of
ROG, NOX, PM10, and PM2.5 associated with off-road equipment use (i.e. excavators, front loaders,
pavers, dump trucks, cranes, and backhoes), material and equipment delivery trips, worker commute
trips, and other miscellaneous activities. Construction activities would be relatively small in scale,
occur intermittently in different locations throughout the city, last for only short periods of time, and
would not require substantial relocation of construction workers from areas outside of the city and
the San Diego region. The CAP Update includes measures that would reduce air pollutant emissions
during construction activities. For example, measure OR-2 would increase the use of renewable and
alternative fuel construction equipment, while Measure T-9 would establish city fleet regulations for
idling, thus reducing construction vehicle idling time and further reducing construction related air
pollutant emissions. Due to the non-intensive, sporadic, and dispersed nature of these construction
activities, emissions of criteria air pollutants would not occur in concentrations which would exceed
SDAPCD thresholds and would therefore be consistent with the goals of the San Diego Regional Air
Quality Strategy or State Implementation Plan. Therefore, mitigation measure AQ-1 identified in the
SEIR would not apply to the construction related air pollutant emissions of the CAP Update. Mitigation
measure AQ-1 identified in the SEIR applies specifically to the construction impacts associated with
housing development projects permitted under implementation of the Housing Element Update, and
would therefore not apply to the CAP Update.

Climate Action Plan Update
28 Addendum
The CAP Update includes several measures (T-4, T-5) that would reduce GHG and vehicle miles
traveled (VMT) through the expansion of bicycle infrastructure, and increased connectivity of sidewalk
networks. Although there would be a temporary, nominal amount of vehicle trips related to
construction worker commute and equipment delivery associated with bike and sidewalk
improvements and other construction activities resulting from CAP Update implementation, the CAP
Update would not result in result in a cumulatively considerable net increase of any criteria pollutant
for which the project region is non-attainment under an applicable federal or State ambient air quality
standard. Therefore, mitigation measure AQ-2 identified in the SEIR would not apply to the CAP
Update.
Measures that would result in new zero emission vehicle and bicycle charging stations (T-8),
roundabouts (T-1), improved bicycle infrastructure (T-4), solar carports (E-3.3) would result in minor
criteria air pollutant and TAC emissions during construction. It is unlikely that these types of activities
would be of the size, intensity, or duration to exceed SDAPCD thresholds of significance or to emit
substantial TAC concentrations. Measure WD-1 would increase the diversion of solid and organic
waste from landfills which could lead to increased haul truck trips to and from composting and
recycling facilities; however, it is anticipated that these trips would displace the haul truck trips that
would be diverted from the landfill. A substantial net increase in the number of haul truck trips and
associated criteria air pollutant emissions within the city would not be anticipated. Furthermore, these
haul truck trips would likely be infrequent and would not involve the trucks idling for extended periods
of time near sensitive receptors. As such, implementation of the CAP Update would not expose off-
site sensitive receptors to substantial pollution concentrations. Therefore, mitigation measures AQ-3
and AQ-4 identified in the SEIR would not apply to the CAP Update.
Construction activities that would occur under CAP Update implementation would result in temporary
generation of odorous emissions. However, consistent with the less than significant impact
determination of the 2024 SEIR, given the temporary and intermittent nature of the impacts, and
dissipation of odor, construction-related odor impacts would be minor. Furthermore, construction
activities would be required to comply with SDAPCD Rule 51 (Nuisance), which regulates nuisance
odors (SDAPCD 1976).
Long-term changes resulting from implementation of the CAP Update would reduce GHG emissions
generated within the city by implementing numerous transportation-, water-, waste-, and energy-
related measures. For example, the implementation of the CAP Update would encourage the use of
alternatively fueled vehicles through measures such as Measure T-8 which would involve installing and
incentivizing public zero emission vehicle and bicycle infrastructure. This would reduce overall gasoline
and fuel consumption, therefore reducing air pollutant emissions related to fossil fuel combustion.
Other transportation-related measures such as Measures T-5, T-7, and T-10 would reduce VMT in the
city by improving street connectivity, provide resources and incentives for alternative commutes, such
as a carpool matching, and implement parking management strategies. Reducing VMT would reduce
the emission of air pollutants by decreasing the consumption of fossil fuel in vehicles and reducing
emissions related to tire and brake wear.
Actions aimed at diverting and eliminating solid waste from disposal in landfills would generate
compostable materials and demand for compost products (e.g., Measure WD-1), which would lead to a
need for haul trucks to transport these materials. Truck trips for hauling of organic waste to processing
facilities would be offset by reductions in truck trips to landfills. Organic waste collected in the city is
recycled at a Republic Services composting facility in Otay (City of Carlsbad 2024).

Energy-related measures such as Measure E-3.1 would continue to implement and enforce the city’s
reach code which is focused on requiring solar photovoltaic (PV) and other energy efficiency measures
for new and existing nonresidential buildings, while Measure E-3.3 focuses on the installation of solar
carports at city-owned parking lots. While these reduction measures were formulated to reduce GHGs,
they would also improve overall air quality by reducing the emission of criteria air pollutants. A higher
proportion of buildings powered by more efficient and/or renewable electric systems due to
implementation of Measure E-3.1 would reduce natural gas combustion at nonresidential land uses
within the city, which would also reduce local criteria air pollution. The effects associated with the
reduction of air pollutant emissions in the city and SDAPCD would be largely beneficial and would, by
nature, reduce the concentration of air pollutants. Therefore, operational activities under
implementation of the CAP Update would not result in the exceedance of SDAPCD thresholds and
would be considered consistent with the goals of the San Diego Regional Air Quality Strategy or State
Implementation Plan. Operational activities would also not violate air quality standards or contribute
to an existing air quality violation because project-related emissions would not exceed SDAPCD
thresholds or result in a cumulatively considerable net increase of criteria pollutants for which the
region is nonattainment under applicable federal or State ambient air quality standards.
The operation of the measures and actions in the CAP Update would not expose off-site sensitive
receptors to substantial pollution concentrations. Measure WD-1 would result in increased odors from
the anaerobic decomposition of composted waste and haul truck trips to composting facilities. These
impacts would be avoided through implementation of an Odor Impact Minimization Plan (OIMP) as
required by State regulation. Therefore, the CAP Update would not result in new emissions (such as
those leading to odors) adversely affecting a substantial number of people.
Conclusion
There are no changes in circumstances or new information of substantial importance that would
require major revisions to the 2024 SEIR or result in new significant effects or a substantial increase in
the severity of previously identified effects related to air quality. Implementation of mitigation
measures AQ-1 through AQ-4 from the SEIR are not applicable to the air quality impacts of the CAP
Update. The CAP Update would not result in any new or substantially more severe significant impacts
related to air quality. Applicable Mitigation Measures from the SEIR
The SEIR identified mitigation measures AQ-1 through AQ-4 for air quality impacts. None of these
mitigation measures are applicable to the CAP Update.

Previous CEQA Analysis Biological Resources Findings
The 2024 SEIR identified a less than significant impact related to a substantial adverse effect, either
directly or through habitat modifications, on any species identified as a candidate, sensitive, or special
status species in local or regional plans, policies, or regulations, or by the California Department of Fish
and Wildlife or US Fish and Wildlife Service (BIO-1) with implementation of mitigation measures BIO-
1 and BIO-2. The 2024 SEIR identified a less than significant impact to any riparian habitat or other
sensitive natural community identified in local or regional plans, policies, regulations or by the
California Department of Fish and Wildlife or US Fish and Wildlife Service (BIO-2) with implementation
of mitigation measures BIO-1, BIO-3, and BIO-4. The 2024 SEIR identified a less than significant impact
to State or federally protected wetlands (including, but not limited to, marsh, vernal pool, coastal, etc.)
(BIO-3) with implementation of mitigation measures BIO-1, BIO-3, BIO-4, and BIO-5. The 2024 SEIR
identified a less than significant impact to interfering substantially with the movement of any native
resident or migratory fish or wildlife species or with established native resident or migratory wildlife
corridors, or impeding the use of native wildlife nursery sites (BIO-4) with implementation of
mitigation measures BIO-1, BIO-3, and BIO-4. The 2024 SEIR identified a less than significant impact
related to conflicts with any local policies or ordinances protecting biological resources, such as a tree
preservation policy or ordinance (BIO-5) with implementation of mitigation measure BIO-6. The 2024
SEIR identified a less than significant impact related to conflicts with the provisions of an adopted
Habitat Conservation Plan, Natural Community Conservation Plan, or other approved local, regional,
or State habitat conservation plan (BIO-6) with implementation of mitigation measures BIO-1, BIO-2,
BIO-3, BIO-4, BIO-7 and BIO-8 (Section 4.3, Biological Resources).
Addendum Analysis
Implementation of the CAP Update would include measures and actions that involve construction and
ground disturbing activities, including minor grading and excavation. For example, Measures T-1, T-4, T-
5, T-8, and T-9 would involve removing existing pavement; repaving roadway surfaces; painting or
restriping pavement; modifying curbs; laying concrete, and installing traffic signals, lighting, landscaping,
and trees. Some of these improvements, such as Measures E-3.3, W-1, and W-2, would require limited
ground disturbance from construction activities. The CAP Update consists of minor improvements and
building retrofits within the city and construction activities would occur in previously disturbed,
developed areas such as roadways and parking lots that lack natural habitat and where candidate,
sensitive, or special-status species or their habitats are not present. Therefore, implementation of the
CAP Update would not cause a substantial adverse direct or indirect effect to special-status species.
Because implementation of the CAP Update would occur in previously disturbed, developed areas,
implementation of the CAP Update would not occur in areas where riparian habitat or other sensitive
natural communities, protected wetlands, wildlife corridors, and protected biological resources are
present. Furthermore, implementation of mitigation measure BIO-2 would reduce any impacts to
candidate, sensitive, or special status species in local or regional plans, policies, or regulations, or by the
California Department of Fish and Wildlife or US Fish and Wildlife Service because the pre-construction
bird surveys would ensure that active nests are identified and as necessary avoided. Implementation of
mitigation measure BIO-2 would also reduce conflicts with the city’s Habitat Conservation Plan, Natural
Community Conservation Plan, or other approved local, regional, or State habitat conservation plans
because it would assure compliance with the Migratory Bird Treaty Act (MBTA) and California Fish and
Game Code (CFGC) Section 3503. Implementation of mitigation measure BIO-6 would reduce any
conflicts with any local policies or ordinances protecting biological resources, such as a tree preservation
policy or ordinance because it would require a project-specific tree survey to determine measures to
address impacts such as avoidance, minimization, restoration, or compensation.

Addendum No. 1 Housing Element Implementation and Public Safety Element Update SEIR 33
Because duration of construction activities would be limited to relatively short periods, their
temporary effects on biological resources would not be substantial.
Long-term changes resulting from implementation of CAP Update measures would include
improvements at or near grade level of existing roadways, as well as minor changes to traffic
intersections and walkways (through implementation of Measures T-1, T-4, T-5, T-8, and T-9),
improvements to water and wastewater systems (Measures W-1 and W-2), planting of trees (through
implementation of Measure CS-1). Implementation of Measures T-1, T-4, T-5, T-8, and T-9 would also
result in the installation of new sidewalks, new and upgraded bikeways and walkways along existing
developed roadways and rights-of-way in the city, and the installation of roundabouts or control traffic
within the intersections of existing developed roadways. The CAP Update would not result in physical
improvements or effects that would result in substantial long-term damage to biological resources.
Conclusion
There are no changes in circumstances or new information of substantial importance that would
require major revisions to the 2024 SEIR or result in new significant effects or a substantial increase in
the severity of previously identified effects related to biological resources. Implementation of
mitigation measures BIO-1, BIO-3, BIO-4, BIO-5, BIO-7, and BIO-8 from the SEIR are not applicable to
the CAP Update. Implementation of mitigation measure BIO-2 would ensure a less-than-significant
impact to special-status biological resources. Implementation of mitigation measure BIO-6 would
ensure a less-than-significant impact for conflict with any local policies or ordinances protecting
biological resources, such as a tree preservation policy or ordinance. The CAP Update would not result
in any new or substantially more severe significant impacts related to biological resources. Applicable Mitigation Measures from the SEIR
The CAP Update would not result in more significant impacts related to biological resources. Mitigation
Measures BIO-2 and BIO-6 from the 2024 SEIR would apply to the CAP Update and ensure CAP Update
impacts related to biological resources are less than significant.
BIO-2 Pre-Construction Bird Surveys, Avoidance, and Notification
If construction activities are initiated during the bird nesting season (February 1 – August 31) involving
removal of vegetation or other nesting bird habitat, including abandoned structures and other man-
made features, a pre-construction nesting bird survey shall be conducted no more than three days
prior to initiation of ground disturbance and vegetation removal activities. The nesting bird pre-
construction survey shall be conducted on foot and shall include a 300-foot survey buffer around the
construction site. The survey shall be conducted by a biologist familiar with the identification of avian
species known to occur in southern California coastal communities (i.e., qualified biologist). If active
nests are found, an avoidance buffer shall be determined by a qualified biologist in coordination with
the city. The avoidance buffer width will depend upon the species, the proposed work activity, and
existing disturbances associated with land uses outside of the site, which shall be demarcated by the
biologist with bright orange construction fencing, flagging, construction lathe, or other means to
demarcate the boundary. All construction personnel shall be notified as to the existence of the buffer
zone and to avoid entering the buffer zone during the nesting season. No ground disturbing activities
shall occur within the buffer until the biologist has confirmed that breeding/nesting is completed, and
the young have fledged the nest. Encroachment into the buffer shall occur only at the discretion of
the qualified biologist on the basis that the encroachment will not be detrimental to an active nest. A
report summarizing the pre-construction survey(s) shall be prepared by a qualified biologist and shall
be submitted to the city prior to the commencement of construction activities.

BIO-6 Protected Tree and Tree Canopy Survey
Prior to the issuance of a grading permit, a tree survey shall be conducted by a certified arborist prior
to project construction to tag and assess all trees subject to the city’s Trees and Shrubs Ordinance
(Municipal Code Title 11.12) and/or CFMP. A city arborist will inspect the property and recommend
approving or denying the application in a written report submitted to the City Manager. The city shall
post a letter of notification and a non-removable marking upon the subject tree a minimum of 30 days
prior to its removal. The letter will be posted in a prominent location, visible from a public street and
will include, the location of the tree, the reason for the trees removal, the date of the scheduled
removal, the species of tree to be replanted, the size of the tree to be replanted, the date by which an
appeal must be made to the parks and recreation commission, and a description of the appeal process.
The following measures shall be implemented in addition to those required under the city’s permits
required for tree removal and maintenance ordinance Guidelines (Municipal Code Title 11.12.090) to
avoid and/or compensate for potential indirect impacts to preserved sensitive natural communities
and protected trees within Carlsbad before, during, and following construction activities.
PRE-CONSTRUCTION
• Fencing. Protective fencing at least three feet high with signs and flagging shall be erected
around all preserved sensitive natural communities where adjacent to proposed vegetation
clearing and grubbing, grading, or other construction activities. The protective fence shall be
installed at a minimum of five feet beyond the tree canopy dripline. The intent of protection
fencing is to prevent inadvertent limb/vegetation damage, root damage and/or compaction
by construction equipment. The protective fencing shall be depicted on all construction plans
and maps provided to contractors and labeled clearly to prohibit entry, and the placement of
the fence in the field shall be approved by a qualified biologist prior to initiation of
construction activities. The contractor shall maintain the fence to keep it upright, taut and
aligned at all times. Fencing shall be removed only after all construction activities are
completed.
• Pre-Construction Meeting. A pre-construction meeting shall be held between all site
contractors and a registered consulting arborist and/or a qualified biologist. All site
contractors and their employees shall provide written acknowledgement of their receiving
sensitive natural community protection training. This training shall include, but shall not be
limited to, the following information: (1) the location and marking of protected sensitive
natural communities; (2) the necessity of preventing damage to these sensitive natural
communities; and (3) a discussion of work practices that shall accomplish such.
DURING CONSTRUCTION
• Fence Monitoring. The protective fence shall be monitored regularly (at least weekly) during
construction activities to ensure that the fencing remains intact and functional, and that no
encroachment has occurred into the protected natural community; any repairs to the fence
or encroachment correction shall be conducted immediately.
• Equipment Operation and Storage. Contractors shall avoid using heavy equipment around
the sensitive natural communities. Operating heavy machinery around the root zones of
trees would increase soil compaction, which decreases soil aeration and, subsequently,
reduces water penetration into the soil. All heavy equipment and vehicles shall, at minimum,
stay out of the fenced protected zones, unless where specifically approved in writing and
under the supervision of a registered consulting arborist and/or a qualified biologist.

Addendum Evaluation
Addendum No. 1 Housing Element Implementation and Public Safety Element Update SEIR 35
• Materials Storage and Disposal. Contractors shall not store or discard any construction
materials within the fenced protected zones and shall remove all foreign debris within these
areas. The contractors shall leave the duff, mulch, chips, and leaves around the retained
trees for water retention and nutrient supply. Contractors shall avoid draining or leakage of
equipment fluids near retained trees. Fluids such as gasoline, diesel, oils, hydraulics, brake
and transmission fluids, paint, paint thinners, and glycol (anti-freeze) shall be disposed of
properly. The contractors shall ensure that equipment be parked at least 50 feet, and that
equipment/vehicle refueling occur at least 100 feet, from fenced protected zones to avoid
the possibility of leakage of equipment fluids into the soil.
• Grade Changes. Contractors shall ensure that grade changes, including adding fill, shall not
be permitted within the fenced protected zone without special written authorization and
under supervision by a registered consulting arborist and/or a qualified biologist. Lowering
the grade within the fenced protected zones could necessitate cutting main support and
feeder roots, thus jeopardizing the health and structural integrity of the tree(s). Adding soil,
even temporarily, on top of the existing grade could compact the soil further, and decrease
both water and air availability to the tree roots. Contractors shall ensure that grade changes
made outside of the fenced protected zone shall not create conditions that allow water to
pond.
• Trenching. Except where specifically approved in writing beforehand, all trenching shall be
outside of the fenced protected zone. Roots primarily extend in a horizontal direction
forming a support base to the tree similar to the base of a wineglass. Where trenching is
necessary in areas that contain roots from retained trees, contractors shall use trenching
techniques that include the use of either a root pruner (Dosko root pruner or equivalent) or
an Air-Spade to limit root impacts. An International Society of Arboriculture (ISA) certified
arborist or American Society of Consulting Arborists (ASCA) registered consulting arborist
shall ensure that all pruning cuts shall be clean and sharp, to minimize ripping, tearing, and
fracturing of the root system. Root damage caused by backhoes, earthmovers, dozers, or
graders is severe and may ultimately result in tree mortality. Use of both root pruning and
Air-Spade equipment shall be accompanied only by hand tools to remove soil from trench
locations. The trench shall be made no deeper than necessary.
• Erosion Control. Appropriate erosion control best management practices (BMPs) shall be
implemented to protect preserved sensitive natural communities during and following
project construction. Erosion control materials shall be certified as weed free.
• Inspection. An ISA certified arborist or ASCA registered consulting arborist shall inspect the
preserved trees adjacent to grading and construction activity on a monthly basis for the
duration of the grading and construction activities. A report summarizing site conditions,
observations, tree health, and recommendations for minimizing tree damage shall be
submitted by the registered consulting arborist following each inspection.
POST-CONSTRUCTION
• Mulch. The contractors shall ensure that the natural duff layer under all trees adjacent to
construction activities shall be maintained. This would stabilize soil temperatures in root zones,
conserve soil moisture, and reduce erosion. The contractors shall ensure that the mulch be
kept clear of the trunk base to avoid creating conditions favorable to the establishment and
growth of decay causing fungal pathogens. Should it be necessary to add organic mulch
beneath retained oak trees, packaged or commercial oak leaf mulch shall not be used as it may

36
contain root fungus. Also, the use of redwood chips shall be avoided as certain inhibitive
chemicals may be present in the wood. Other wood chips and crushed walnut shells can be
used, but the best mulch that provides a source of nutrients for the tree is its own leaf litter.
Any added organic mulch added by the contractors shall be applied to a maximum depth of 4
inches where possible.
• Watering Adjacent Plant Material. All installed landscaping plants near the preserved
sensitive natural communities shall require moderate to low levels of water. The surrounding
plants shall be watered infrequently with deep soaks and allowed to dry out in-between,
rather than frequent light irrigation. The soil shall not be allowed to become saturated or stay
continually wet, nor should drainage allow ponding of water. Irrigation spray shall not hit the
trunk of any tree. The contractors shall maintain a 30-inch dry-zone around all tree trunks. An
above ground micro-spray irrigation system shall be used in lieu of typical underground pop-
up sprays.
• Monitoring. An ISA certified arborist or ASCA registered consulting arborist shall inspect the
trees preserved on the site adjacent to construction activities for a period of two years following
the completion of construction. Monitoring visits shall be completed quarterly, totaling eight
visits. Following each monitoring visit, a report summarizing site conditions, observations, tree
health, and recommendations for promoting tree health shall be submitted to the city.
Additionally, any tree mortality shall be noted and any tree dying during the two-year
monitoring period shall be replaced at a minimum 3:1 ratio on-site in coordination with the city.

Previous CEQA Analysis Cultural Resources Findings
The 2024 SEIR identified a significant and unavoidable impact related to a substantial adverse change in
the significance of a historical resource pursuant to §15064.5 and identified no feasible mitigation
measures (CUL-1). The 2024 SEIR identified a less than significant impact related to a substantial adverse
change in the significance of an archaeological resource pursuant to §15064.5 (CUL-2). The 2024 SEIR
also identified a less than significant impact for disturbing any human remains, including those interred
outside of formal cemeteries (CUL-3) (Section 4.4, Cultural and Tribal Cultural Resources).
Addendum Analysis
Implementation of the CAP Update would result in physical changes to the environment that could
occur in proximity to or involve encountering historical resources. For example, some improvements
that result from the CAP Update, such as Measures T-1, T-4, T-5, T-8, T-9, CS-1, E-3.3, W-1, and W-2,
would require limited ground disturbance. Energy efficiency improvements and building retrofits
(Measure E-6) would involve minor changes to the exterior (e.g., rooftop solar panels) or interior (e.g.,
water heating and space heating and cooling systems) of existing buildings, and would not otherwise
involve features with substantial height, bulk, or massing that would cause a substantial adverse change
to a historic resource. Adherence to the relevant General Plan policies, the Historic Preservation
Ordinance, and the relevant elements of the Carlsbad Cultural Resource Guidelines would protect
historical resources from substantial adverse changes during CAP Update implementation.
Because ground disturbance associated with the implementation of CAP Update Measures T-1, T-4, T-
5, T-8, T-9, CS-1, E-3.3, W-1, and W-2 would be limited to shallow depths, comprised of artificial fill or
previously disturbed soils, archaeological resources are unlikely to be encountered. In addition,
construction activities associated with CAP Update implementation would occur in already disturbed
developed areas such as roadways and parking lots. Zero emission vehicle charging stations (Measure
T-8) would be installed in new and existing developments, and roadway improvements such as
roundabouts, traffic circles, walkways, and bicycle infrastructure would occur along existing developed
roadways. In addition, tree planting associated with Measure CS-1 would likely occur within city parks
and public rights-of-way. Furthermore, the Carlsbad Cultural Resource Guidelines addresses treatment
of cultural resources to avoid substantial adverse effects should they be encountered during ground
disturbance activities associated with the CAP Update. Therefore, with adherence to the Carlsbad
Cultural Resource Guidelines, implementation of the CAP Update would not cause a substantial
adverse change in the significance of an archaeological resource pursuant to §15064.5.
The Carlsbad Cultural Resource Guidelines Standard Treatment 11: Post-Review Discoveries section
addresses treatment of human remains should they be disturbed as a result of ground disturbing
activities. Moreover, human burials, in addition to being potential archaeological resources, have
specific provisions for treatment in Public Resources Code (PRC) Section 5097. The California Health
and Safety Code (Section 7050.5, 7051, and 7054) has specific provisions for the protection of human
burial remains. Existing regulations address the illegality of interfering with human burial remains, and
protect them from disturbance, vandalism, or destruction. They also include established procedures
to be implemented if Native American skeletal remains are discovered. PRC Section 5097.98 also
addresses the disposition of Native American burials, protects such remains, and provides for the
establishment of the NAHC to resolve any related disputes. All development projects are also subject
to State of California Health and Safety Code Section 7050.5 which states that, if human remains are
unearthed, no further disturbance can occur until the county coroner has made the necessary findings
as to the origin and disposition of the remains pursuant to the PRC Section 5097.98.

If the remains are determined to be of Native American descent, the coroner has 24 hours to notify
the Native American Heritage Commission which will determine and notify a most likely descendant

landowner within 48 hours of being granted access. With adherence to these existing regulations as
well as the Carlsbad Cultural Resource Guidelines, implementation of the CAP Update would not
disturb any human remains, including those interred outside of formal cemeteries.
Conclusion
There are no changes in circumstances or new information of substantial importance that would
require major revisions to the 2024 SEIR or result in new significant effects or a substantial increase in
the severity of previously identified effects related to cultural resources. The 2024 SEIR identified a
significant and unavoidable impact for cultural resources (CUL-1) and did not identify feasible
mitigation measures. The CAP Update would not result in any new or substantially more severe
significant impacts related to cultural resources. Applicable Mitigation Measures from the SEIR
There are no feasible mitigation measures from the 2024 SEIR to reduce impacts related to cultural
resources.

Addendum No. 1 Housing Element Implementation and Public Safety Element Update SEIR 41
Previous CEQA Analysis Energy Findings
The 2024 SEIR identified no impact for the wasteful, inefficient, or unnecessary consumption of energy
resources, during project construction or operation or for conflicts with or obstruction of a State or
local plan for renewable energy or energy efficiency (Section 4.16.2, Energy).
Addendum Analysis
Construction activities associated with implementation of the CAP Update measures and actions
would result in short-term consumption of energy resulting from the use of construction equipment.
The types of construction activities associated with the CAP Update would vary depending on the type
of CAP Update measure. Examples of activities that would result from implementation of CAP Update
measures include construction of new public zero emission vehicle and bicycle charging infrastructure,
building efficiency retrofits, roundabouts or traffic circles, bicycle infrastructure, new solar carports,
and water and wastewater system improvements (e.g., Measures T-1, T-2, T-3, T-4, T-5, T-8, T-9, E-3.3,
W-1, and W-2). These activities would consume energy resources such as electricity, fuels, and non-
renewable resources during construction. In addition, construction materials require energy to be
produced, and would likely be used in projects that involve new construction or replacement of older
materials. The California Green Building Standards Code (CALGreen) includes specific requirements
related to recycling, construction materials, and energy efficiency standards, which would apply to
construction projects envisioned by the CAP Update and help to minimize waste and energy
consumption. Although implementation of the CAP Update would result in short-term construction
activities that would consume energy resources, standard best management practices would discourage
unnecessary idling and the operation of poorly maintained equipment during construction. In addition,
the CAP Update includes measures that would reduce nonrenewable energy consumption during
construction activities. For example, Measure OR-2 would increase the use of renewable and
alternative fuel construction equipment, while Measure T-9 would establish city fleet regulations for
idling, thus reducing construction vehicle idling time and further reducing construction related energy
consumption.
Implementation of the CAP Update would improve operational energy efficiency and reduce the use of
fossil fuels, for example through measures which reduce VMT (Measure T-2) and encourage zero
emission vehicle use (Measure T-8), as well as measures which facilitate the increased generation and
utilization of renewable energy Measures E-1 through E-6). The measures and actions in the CAP Update
reduce GHG emissions, primarily by improving energy efficiency and decreasing consumption of fossil
fuels and nonrenewable energy consumption. Thus, implementation of the CAP Update would not result
in wasteful, inefficient, or unnecessary consumption of energy, consistent with the SEIR findings.
Where applicable, measures and actions associated with the CAP Update would be required to comply
with CALGreen, the latest California Building Code (CBC) requirements, including CBC Energy Efficiency
Standards, as well as all federal, State, and local rules and regulations pertaining to energy
consumption and conservation. Through implementation of city policies as delineated in the city’s
General Plan, and concurrent implementation of the CAP Update, measures and actions would support
the San Diego Regional Energy Strategy renewable energy goals and would not conflict with any
applicable plan, policy, or regulation adopted regarding renewable energy or energy efficiency.

Addendum No. 1 Housing Element Implementation and Public Safety Element Update SEIR 45
Previous CEQA Analysis Geology and Soils Findings
The 2024 SEIR identified less than significant impacts for the risk of loss, injury, or death involving
rupture of a known earthquake fault, as delineated on the most recent Alquist-Priolo Earthquake Fault
Zoning Map issued by the State Geologist for the area or based on other substantial evidence of a
known fault (GEO-1); and for the risk of loss, injury, or death involving strong seismic ground shaking,
seismic-related ground failure, including liquefaction or landslides (GEO-2). The 2024 SEIR also
identified less than significant impacts for substantial soil erosion or the loss of topsoil (GEO-3) and for
on or off-site landslide, lateral spreading, subsidence, liquefaction or collapse, and location on
expansive soils creating substantial direct or indirect risks to life or property (GEO-4). The 2024 SEIR
identified less than significant impacts for soils incapable of adequately supporting the use of septic
tanks or alternative wastewater disposal systems where sewers are not available for the disposal of
wastewater (GEO-5) and for the project to directly or indirectly destroy a unique paleontological
resource or site or unique geologic feature (GEO-6) (Section 4.5, Geology and Soils).
Addendum Analysis
Measures and actions associated with the CAP Update include improvements to energy infrastructure
(Measures E-1 through E-6), development of roundabouts (Measure T-1), bicycle infrastructure
(Measure T-4), pedestrian infrastructure (Measure T-5), and improvements to water and wastewater
infrastructure (Measures W-1, W-2). The measures identified in the CAP Update do not propose new
housing nor do they propose changes to policies or regulations related to land use or residential zoning.
Therefore, the CAP Update would not result in the risk of loss, injury, or death involving rupture of a
known earthquake fault, as delineated on the most recent Alquist-Priolo Earthquake Fault Zoning Map
issued by the State Geologist for the area or based on other substantial evidence of a known fault or
result in the risk of loss, injury, or death involving strong seismic ground shaking, seismic-related ground
failure, including liquefaction or landslides. The CAP Update would not result in substantial soil erosion
or the loss of topsoil or result in on or off-site landslide, lateral spreading, subsidence, liquefaction or
collapse, and location on expansive soils creating substantial direct or indirect risks to life or property.
The measures and actions in the CAP Update would not require use of septic tanks or alternative
wastewater disposal systems where sewers are not available for the disposal of wastewater.
Implementation of the CAP Update would include measures and actions (Measures T-1, T-4, T-5, T-8, T-
9, CS-1, E-3.3, W-1, and W-2) that involve ground disturbing activities which could encounter
paleontological resources in areas with moderate to high sensitivity. While encountering paleontological
resources is possible during CAP Update implementation, it is unlikely because of the shallow depth of
below ground disturbance associated with activities such as trenching to install zero emission vehicle
and bicycle charging infrastructure and making improvements to public roadway rights-of-way to
support walking and biking. For measures and actions requiring ground disturbance in areas underlain
by sensitive geologic units, the Carlsbad Cultural Resource Guidelines require a review of primary
literature and online databases, a paleontological assessment of the project area (plus a one-mile radius)
by the San Diego Museum of Natural History, and a field survey to determine if paleontological resources
or potentially fossiliferous sediments are present (if the sensitive sediments are exposed at the surface).
The results of these analyses are used to create a Paleontological Assessment Report which will provide
recommendations to mitigate impacts to paleontological resources, if necessary. The Carlsbad Cultural
Resource Guidelines set forth mitigation measures.
Additionally, General Plan policies 7-P.7 through 7-P.11 of the Arts, History, Culture, and Education
Element would reduce impacts to paleontological resources by implementing the Carlsbad Cultural
Resource Guidelines; requiring monitoring of ground-disturbing activities in areas known to contain

46
paleontological resources; and ensuring proper treatment and consultation of paleontological resources
discovered during ground-disturbing activities. With compliance with these guidelines and General Plan
policies, implementation of the CAP Update would not directly or indirectly destroy a unique
paleontological resource or site or unique geologic feature.
Conclusion
There are no changes in circumstances or new information of substantial importance that would
require major revisions to the 2024 SEIR or result in new significant effects or a substantial increase in
the severity of previously identified effects related to geology and soils. The 2024 SEIR did not identify
significant geology and soils impacts and did not identify mitigation measures. The CAP Update would
not result in any new or substantially more severe significant impacts related to geology and soils. Applicable Mitigation Measures from the SEIR
There are no mitigation measures from the 2024 SEIR identified to reduce impacts related to geology
and soils.

Previous CEQA Analysis Greenhouse Gas Emissions Findings
The 2024 SEIR identified a significant and unavoidable impact for generating greenhouse gas
emissions, either directly or indirectly, that may have a significant impact on the environment and for
conflicting with an applicable plan, policy, or regulation adopted for the purpose of reducing the
emissions of greenhouse gases (GHG-1). It identifies Mitigation Measure GHG-1, which requires the
preparation of this CAP Update to reduce the GHG emissions impacts identified in the 2024 SEIR
(Section 4.6, Greenhouse Gas Emissions).
Addendum Analysis
The CAP Update establishes measures and actions that would reduce GHG emissions in Carlsbad to
levels that achieve its GHG reduction targets, which are aligned with the State’s GHG reduction goals.
The city’s 2035 target requires GHG emissions to be reduced 50 percent below 2016 levels (aligned
with and extrapolated from SB 32) and reduced to 85 percent below 2016 levels by 2045 (aligned with
AB 1279). The CAP Update measures and actions would meet the city’s GHG reduction targets.
In addition, implementation of the CAP Update would result in physical changes to the environment
that would involve short-term physical changes that could result in GHG emissions. Several of the
measures and actions identified in the CAP Update promote construction of new facilities or retrofitting
of existing facilities that would generate construction-related GHG emissions. Some examples of
activities that would generate construction-related GHG emissions include retrofitting of existing
buildings and developments to transition to renewable energy generation (Measures E-1, E-6, W-1, and
W-2), constructing roundabouts or traffic circles (Measure T-1), installation of solar carports (Measure
E-3.3), installation of zero emission vehicle charging stations (Measure T-8), improvements to
pedestrian and bicycling infrastructure (Measures T-5 and T-4), and implementation of activities related
to urban tree planting (Measure CS-1).
Implementation of the CAP Update would reduce overall GHG emissions generated within the city, for
example by encouraging the use of alternative fuels in vehicles and equipment (Measures T-8, OR-1, and
OR-2), reducing VMT (Measures T-5, T-7, and T-10), improving energy efficiency (Measures E-1 through
E-6), reducing waste generation (Measure WD-1), and increasing carbon sequestration (Measure CS-1).
In addition, measures that support energy efficiency and renewable energy generation would reduce
GHG emissions at power plants generating electricity that serve the city. Thus, any temporary GHG
emissions would be offset by the overall net benefit of GHG emissions reduction after implementation
of the CAP Update. Therefore, implementation of the CAP Update would not generate GHG emissions,
either directly or indirectly, that may have a significant impact on the environment, nor would
implementation of the CAP Update conflict with an applicable plan, policy, or regulation adopted for the
purpose of reducing the emissions of GHGs.
Conclusion
There are no changes in circumstances or new information of substantial importance that would require
major revisions to the 2024 SEIR or result in new significant effects or a substantial increase in the severity
of previously identified effects related to GHG emissions. Implementation of Mitigation Measure GHG-1,
which requires preparation of the CAP Update evaluated in this Addendum No. 1, would be satisfied by
preparation of the CAP Update, and therefore is not applicable to actions implementing the CAP Update.
The CAP Update would not result in any new or substantially more severe significant impacts related to
GHG emissions.

Previous CEQA Analysis Hazards and Hazardous Materials Findings
The 2024 SEIR identified less than significant impacts for the routine transport, use, or disposal of
hazardous materials and reasonably foreseeable upset and accident conditions involving the release
of hazardous materials (HAZ-1); emitting or handling hazardous or acutely hazardous materials,
substances, or waste within one-quarter mile of an existing or proposed school (HAZ-2); being located
on a site which is included on a list of hazardous materials sites compiled pursuant to Government
Code Section 65962.5 and creating a significant hazard to the public or the environment (HAZ-3); being
located within an airport land use plan or within two miles of a public airport or public use airport and
resulting in a safety hazard or excessive noise for people residing or working in the project area (HAZ-
4); and for impairing implementation of or physically interfering with an adopted emergency response
plan or emergency evacuation plan (HAZ-5) (Section 4.7, Hazards and Hazardous Materials).
Addendum Analysis
The implementation of the CAP Update measures and actions would result in short-term and long-
term changes related to hazards and hazardous materials as described below.
Construction activities and routine maintenance associated with implementation of the CAP Update
would result in short-term, temporary changes to hazards and hazardous materials conditions in the
city. Although the types of construction activities associated with the CAP Update would vary
depending on the type of CAP Update measure, they could result in an increase in the overall routine,
transport, use and disposal of hazardous materials in the city for construction activities. For example,
Measures T-1, T-4, T-5, T-8, and T-9 would involve removing existing pavement; repaving roadway
surfaces; painting or restriping pavement; modifying curbs; laying concrete, and installing traffic
signals, lighting, landscaping, street furniture, and other amenities. Construction activities would be
short-term and temporary and would be required to comply with relevant federal, State, and local
regulations that require strict adherence to guidelines regarding the safe use, transportation, and
disposal of hazardous materials as well as ensuring the reduction of the potential for humans or the
environment to be affected by an accidental release of hazardous materials. Enforcement of these
regulatory standards would ensure that the measures and actions facilitated by implementation of the
CAP Update would not create a significant hazard through reasonably foreseeable upset and/or
accident conditions involving the release of hazardous materials into the environment. Compliance
with applicable regulations would ensure that any hazardous materials used during the
implementation of the CAP Update would not result in hazardous emissions within one-quarter mile
of an existing or proposed school.
Some improvements as a result of the CAP Update, such as Measures E-3.3, W-1, and W-2, would
require limited ground disturbance which could result in the release of contaminants into the
environment, if they are present in the underlying soils and/or groundwater. In the event that CAP
Update implementation results in ground disturbance, any residual contamination that is encountered
would be remediated to allowable regulatory levels in accordance with applicable county and State
regulations before any ground-disturbing activities are permitted to occur. Therefore, implementation
of the CAP Update would not result in a significant hazard to the public or the environment due to
being located on a hazardous materials site.
The McClellan–Palomar Airport is located near the center of the city and has a Land Use Compatibility
Plan (ALUCP) developed and adopted by the San Diego County Airport Land Use Commission in 2010
and last amended in 2011 (San Diego County Regional Airport Authority 2011). The CAP Update
measures and actions would not result in new or relocated residential land uses, other types of noise-
Oct. 2, 2024 Item #1 76 of 157
Addendum Evaluation
Addendum No. 1 Housing Element Implementation and Public Safety Element Update SEIR 53
sensitive receptors, or new places of permanent employment where residents or workers could be
exposed to a safety hazard or excessive noise. Therefore, implementation of the CAP Update would
not expose residents or workers to a safety hazard or excessive noise levels.
Long-term changes resulting from implementation of CAP Update measures and actions would include
improvements at or near grade level of existing roadways, new and upgraded bikeways and sidewalks
along existing developed roadways and rights-of-way in the city, the installation of roundabouts or
traffic circles to control traffic within the intersections of existing developed roadways, and the
installation of zero emission charging infrastructure (through implementation of Measures T-1, T-4, T-
5, T-8, and T-9). However, these improvements would not adversely affect the capacity of roadways
during an emergency or evacuation. CAP Update Measure T-1, which encourages the installation of
roundabouts, would reduce congestion, thus increasing traffic flow and the ability to evacuate during
an emergency. Furthermore, the CAP Update measures and actions would comply with the San Diego
County Emergency Operations Plan (EOP) and the California Fire Code. Therefore, implementation of
the CAP Update would not impair or interfere with adopted emergency response or evacuation plans.
Conclusion
There are no changes in circumstances or new information of substantial importance that would
require major revisions to the 2024 SEIR or result in new significant effects or a substantial increase in
the severity of previously identified effects related to hazards and hazardous materials. The 2024 SEIR
did not identify significant hazards and hazardous material impacts and did not identify mitigation
measures. The CAP Update would not result in any new or substantially more severe significant
impacts related to hazards and hazardous material. Applicable Mitigation Measures from the SEIR
There are no mitigation measures from the 2024 SEIR identified to reduce impacts related to hazards
and hazardous materials.

Previous CEQA Analysis Hydrology and Water Quality Findings
The 2024 SEIR identified less than significant impacts related to the violation of water quality
standards, waste discharge requirements (WDR’s), or otherwise degradation of surface or ground
water quality (HYD-1); decreasing groundwater supplies or interfering with groundwater recharge
(HYD-2); altering the existing drainage patterns through the alteration of the course of a stream or
river or through the addition of impervious surfaces resulting in substantial erosion or siltation on- or
off-site, increasing the rate or amount of surface runoff in a manner which would result in flooding
on- or off-site, or creating or contributing runoff water which would exceed the capacity of existing or
planned stormwater drainage systems or provide substantial additional sources of polluted runoff
(HYD-3); impede or redirect flood flows or in flood hazard, tsunami, or seiche zones risk release of
pollutants due to project inundation (HYD-4); conflicts with or obstruction of implementation of a
water quality control plan or sustainable groundwater management plan (HYD-5) (Section 4.8,
Hydrology and Water Quality).
Addendum Analysis
The implementation of the CAP Update measures and actions would result in short-term and long-
term changes related to hydrology and water quality as described below.
The CAP Update measures involving construction activity would require minor grading, excavation,
and other ground disturbance associated with removing existing pavement; repaving roadway
surfaces; painting or restriping pavement; modifying curbs; laying concrete, and installing traffic
signals, lighting, landscaping, street furniture, and other amenities (through implementation of
Measures T-1, T-4, T-5, T-8, and T-9). Measures E-3.3, W-1, W-2, and CS-1 would also involve ground-
disturbing activities, which could, depending on their location, potentially cause soil erosion which in
turn can contaminate nearby surface water. However, implementation of the measures and actions in
the CAP Update would be required to comply with State and local water quality regulations designed
to control erosion and protect water quality during construction. This includes compliance with the
requirements of the State Water Resources Control Board (SWRCB) Construction General Permit,
which requires preparation and implementation of a Stormwater Pollution Prevention Plan (SWPPP)
for projects that disturb one acre or more of land. Erosion and sediment controls identified in the
SWPPP would substantially reduce the amount of soil disturbance, erosion, and sediment transport
into receiving waters, and pollutants in site runoff during construction. The CMC also sets forth
requirements and BMPs pertaining to the mitigation of erosion, sediment control and runoff as outlined
in CMC Chapter 15.12 and Chapter 15.16. Through compliance with all applicable regulations and
permits, implementation of the CAP Update would not violate any water quality standards or WDRs
or otherwise substantially degrade water quality; substantially alter the existing drainage pattern of
the site or area, including through the alteration of the course of a stream or river or through the
addition of impervious surfaces, in a manner which would result in substantial erosion or siltation on-
or off-site, increase the rate or amount of surface runoff in a manner which would result in flooding
on- or off-site, or create or contribute runoff water which would exceed the capacity of existing or
planned stormwater drainage systems or provide substantial additional sources of polluted runoff.
The CAP Update measures and actions involving ground disturbing activities (Measures T-1, T-4, T-5,
T-8, T-9, E-3.3, W-1, W-2, CS-1) could require the use of water for dust abatement as needed via a
water truck. However, the ground disturbing activities would be temporary and intermittent and
would not involve the substantial use of groundwater or otherwise affect recharge such that there
would be a net deficit in aquifer volume or a lowering of the local groundwater table level.

Furthermore, implementation of the CAP Update would not involve development of residential land
uses or other types of land development or induce population growth in an area that would increase
water demand. In addition, the city requires new construction and redevelopment to use low impact
development (LID) techniques. These techniques would ensure that pervious surfaces are
incorporated into development that would be facilitated by the project. Therefore, implementation of
the CAP Update would not decrease groundwater supplies or interfere with groundwater recharge.
Long-term changes resulting from implementation of the CAP Update measures would include
improvements at or near grade level of existing roadways, as well as minor changes to traffic intersections
and walkways (through implementation of Measures T-1, T-4, T-5, T-8, and T-9), improvements to water
and wastewater systems (Measures W-1 and W-2), and the planting of trees (through implementation of
Measure CS-1). The CMC requires BMPs to control the volume, rate, and potential pollutant load of
stormwater runoff from new development and redevelopment projects as a requirement of the
Municipal Stormwater Permit. Furthermore, the city’s LID ordinance in Chapter 15.12.080 aims to
specifically reduce the amount of surface runoff and aid in groundwater recharge through techniques
such as infiltration, evapotranspiration, bioretention and/or rainfall harvest and additional uses in
accordance with the requirements set forth in the MS4 permit and the LID standards manual. Given
compliance with the above regulations and requirements, implementation of the CAP Update would not
alter the existing drainage patterns or contribute runoff water in a manner which would result in
substantial erosion, siltation, or flooding, nor would it exceed the capacity of existing or planned
stormwater drainage systems.
Conclusion
There are no changes in circumstances or new information of substantial importance that would
require major revisions to the 2024 SEIR or result in new significant effects or a substantial increase in
the severity of previously identified effects related to hydrology and water quality. The 2024 SEIR did
not identify significant hydrology and water quality impacts and did not identify mitigation measures.
The CAP Update would not result in any new or substantially more severe significant impacts related
to hydrology and water quality. Applicable Mitigation Measures from the SEIR
There are no mitigation measures from the 2024 SEIR identified to reduce impacts related to hydrology
and water quality.

Previous CEQA Analysis Land Use and Planning Findings
The 2024 SEIR identified no impact for physically dividing an established community (LU-1) and a less
than significant impact for conflicts with any land use plan, policy, or regulation (LU-2) (Section 4.9,
Land Use and Planning).
Addendum Analysis
Implementation of the CAP Update would not result in physical improvements that could physically
divide a community. For example, measures resulting in construction of roundabouts or traffic circles
(T-1) and bikeways (T-4) would reduce vehicle congestion and encourage bicycle trips, which would
increase community connectivity and access. Implementation of Measure T-5 would also increase
community connectivity and access by adding 6.1 miles of sidewalk to existing infrastructure and
increasing the connectivity of sidewalk networks. As such, the CAP Update measures and actions are
intended to improve, rather than impair, community connectivity and access throughout the city.
Therefore, implementation of the CAP Update would not result in construction of physical barriers
that would physically divide an established community.
The CAP Update measures and actions would include improvements to the city’s existing pedestrian,
bicycle, and transit network within developed areas (Measures T-1, T-3, T-4, and T-5). Implementation
of the CAP Update would not change existing land uses and would comply with all applicable land use
plans, policies, and regulations, including SANDAG’s 2021 Regional Plan and the city’s 2015 General
Plan. Therefore, implementation of the CAP Update would not cause a significant environmental
impact due to a conflict with any land use plan, policy, or regulation adopted for the purpose of
avoiding or mitigating an environmental effect.
Conclusion
There are no changes in circumstances or new information of substantial importance that would
require major revisions to the 2024 SEIR or result in new significant effects or a substantial increase in
the severity of previously identified effects related to land use and planning. The 2024 SEIR did not
identify significant land use and planning impacts and did not identify mitigation measures. The CAP
Update would not result in any new or substantially more severe significant impacts related to land use
and planning. Applicable Mitigation Measures from the SEIR
There are no mitigation measures from the 2024 SEIR identified to reduce impacts related to land
use and planning.

mineral resource recovery site delineated on a local general plan, specific plan, or other land use plan
(Section 4.16.3, Mineral Resources).
Addendum Analysis
Carlsbad does not have mineral resources of economic value or active mining sites (City of Carlsbad
2015), therefore the 2024 SEIR identified no impacts to the loss of availability of a known mineral
resource that would be of value to the region and the residents of the State, or the loss of availability
of a locally-important mineral resource recovery site delineated on a local general plan, specific plan,
or other land use plan. Similarly, implementation of the CAP Update would not result in the loss of
availability of a known mineral resource that would be of value to the region and the residents of the
State, or result in the loss of availability of a locally-important mineral resource recovery site
delineated on a local general plan, specific plan, or other land use plan.
Conclusion
There are no changes in circumstances or new information of substantial importance that would
require major revisions to the 2024 SEIR or result in new significant effects or a substantial increase in
the severity of previously identified effects related to mineral resources. The 2024 SEIR did not identify
significant mineral resources impacts and did not identify mitigation measures. The CAP Update would
not result in any new or substantially more severe significant impacts related to mineral resources. Applicable Mitigation Measures from the SEIR There are no mitigation measures from the 2024 SEIR identified to reduce impacts related to mineral
resources.

Addendum Evaluation
Addendum No. 1 Housing Element Implementation and Public Safety Element Update SEIR 65
Previous CEQA Analysis Noise Findings
The 2024 SEIR identified that although mitigation measure NOI-1 would reduce construction noise
impacts for projects located within 500 feet of noise-sensitive land uses, it conservatively concluded
impacts to be significant and unavoidable related to construction activities generating a substantial
temporary or permanent increase in ambient noise levels in the vicinity of the project in excess of
standards established in the local general plan or noise ordinance, or applicable standards of other
agencies (NOI-1). The 2024 SEIR identified a less than significant impact related to operational
activities generating a substantial temporary or permanent increase in ambient noise levels in the
vicinity of the project in excess of standards established in the local general plan or noise ordinance,
or applicable standards of other agencies (NOI-2). The 2024 SEIR identified a less than significant
impact related to the generation of excessive groundborne vibration or groundborne noise levels (NOI-
3) with implementation of mitigation measure NOI-2. The 2024 SEIR also identified a less than
significant impact related to excessive noise levels within the vicinity of a private airstrip or an airport
land use plan or (NOI-4) (Section 4.10, Noise).
Addendum Analysis
The implementation of the CAP Update measures and actions would result in short-term changes
related to noise as described below.
Construction activities associated with the implementation of the CAP Update, such as equipment use,
construction of new facilities or retrofitting of existing facilities, would result in construction-related
noise in the city. The types of construction activities associated with the CAP Update would vary
depending on the type of CAP Update measure. CAP Update measures that may result in the
generation of noise associated with construction activities include construction of new public zero
emission vehicle and bicycle charging infrastructure, building efficiency retrofits, roundabouts or
traffic circles, bicycle infrastructure, new solar carports, and water and wastewater system
improvements (e.g., Measures T-1, T-2, T-3, T-4, T-5, T-8, T-9, E-3.3, W-1, and W-2). Construction
activities associated with CAP Update measures and actions may involve using construction equipment
and vehicles to remove existing pavement; repave roadway surfaces; paint or restripe pavement;
modify curbs; lay concrete, and install traffic signals, lighting, landscaping, street furniture, and other
amenities. Construction equipment that could be used includes concrete saws for hardscape removal,
backhoes or mini excavators, skip loaders, smooth drum rollers, dump trucks, and striping and paving
machines, depending on the CAP Update measure. Construction activities associated with the CAP
Update would be short-term and would not involve equipment or activities, such as blasting or pile
driving that would result in the generation of a substantial temporary or permanent increase in
ambient noise levels or the generation of excessive groundborne vibration or groundborne noise levels.
Construction activities associated with the implementation of the CAP Update would not include two
subterranean levels or more (generally more than 20,000 cubic yards of excavated soil material), and
would be short term, thus avoiding a construction duration of 18 months. Construction activities
associated with the implementation of the CAP Update would not require use of large, heavy-duty
equipment types used in housing development projects or require pile driving, therefore, mitigation
measures NOI-1 andNOI-2 identified in the SEIR that were specific to impacts associated with housing
development permitted under implementation of the Housing Element Update would not apply to the
CAP Update.
Implementation of the CAP Update would be subject to existing city noise policies and regulations and
General Plan policies and programs, specifically those found in the Noise Element, and other local
agency polices and regulations pertaining to noise at any development site. Compliance with
Oct. 2, 2024 Item #1 89 of 157
City of Carlsbad
Climate Action Plan Update
66
Occupational Safety and Health Administration (OSHA) standards for worker safety would minimize
exposure of workers to excessive noise levels. Therefore, implementation of measures and actions
included in the CAP Update would not create a permanent increase in ambient noise levels or produce
a new permanent source of noise, and construction-related noise impacts would be reduced through
enforcement of applicable city or other local agency noise policies.
Long-term changes resulting from operation of the measures and actions in the CAP Update would not
permanently introduce any new stationary sources of noise (e.g., machinery, pumps, fans, compressors,
or other equipment) and would not generate new vehicle trips that would result in transportation-
related noise. The transportation-related measures such as Measures T-5, T-7, and T-10 would reduce
VMT in the city by improving street connectivity, provide resources and incentives for alternative
commutes, such as a carpool matching, and implement parking management strategies. Reducing
VMT would reduce transportation-related noise. Therefore, the CAP Update would not result in a
substantial temporary or permanent increase in ambient noise levels in excess of standards established
in the local general plan or noise ordinance, or applicable standards of other agencies or in the
generation of excessive groundborne vibration or groundborne noise levels.
The CAP Update does not propose any new sensitive receptors (e.g., residences, schools) that could
be adversely impacted from noise associated with aircraft flyovers. Temporary construction workers
would not be adversely affected by aircraft flyover as noise generated from construction equipment
would be the dominant noise exposure to them, which is generally dealt with by wearing ear plugs to
prevent hearing damage. Furthermore, long-term maintenance workers would not sleep on-site; thus,
they would not be exposed to potential sleep disturbance from aircraft flyovers. Thus, implementation
of the CAP Update would not expose people residing or working near an airport to excessive
airport/aircraft noise.
Conclusion
There are no changes in circumstances or new information of substantial importance that would
require major revisions to the 2024 SEIR or result in new significant effects or a substantial increase in
the severity of previously identified effects related to noise. Implementation of mitigation measures
NOI-1 and NOI-2 from the 2024 SEIR are not applicable to the CAP Update. The CAP Update would not
result in any new or substantially more severe significant impacts related to noise. Applicable Mitigation Measures from the SEIR
The SEIR identified Mitigation Measures NOI-1 and NOI-2 for noise impacts. Neither of these
mitigation measures are applicable to the CAP Update.

Previous CEQA Analysis Population and Housing Findings
The 2024 SEIR identified less than significant impacts for unplanned population growth (PH-1) and
substantial displacement of existing people or housing, necessitating the construction of replacement
housing elsewhere (PH-2) (Section 4.11, Population and Housing).
Addendum Analysis
Construction activities associated with the implementation of the CAP Update could require a
temporary increase in the number of construction workers traveling into the city to perform
construction work. These types of projects would be small, short-term, and temporary construction
projects, which would not require a large construction crew. Furthermore, construction workers
would likely be from Carlsbad or the greater San Diego region and permanent, substantial relocation
of workers would not be required. Therefore, implementation of the CAP Update would not result in
substantial population growth or employment growth in the city.
Implementation of the CAP Update would not displace people or housing because the measures and
actions in the CAP Update would not require the removal of existing housing and would not propose
changes to policies or regulations related to land use or residential zoning or otherwise increase
population growth in the city or surrounding areas. Therefore, implementation of the CAP Update
would not displace substantial numbers of existing people or housing, necessitating the construction of
replacement housing elsewhere.
Conclusion
There are no changes in circumstances or new information of substantial importance that would
require major revisions to the 2024 SEIR or result in new significant effects or a substantial increase in
the severity of previously identified effects related to population and housing. The 2024 SEIR did not
identify significant population and housing impacts and did not identify mitigation measures. The CAP
Update would not result in any new or substantially more severe significant impacts related to
population and housing. Applicable Mitigation Measures from the SEIR
There are no mitigation measures from the 2024 SEIR identified to reduce impacts related to
population and housing.

impacts, in order to maintain acceptable service ratios, response times, or other performance
objectives for any of the public services, including fire protection services (PS-1), police protection
services (PS-2), and schools (PS-3) (Section 4.12, Public Services and Recreation).
Addendum Analysis
The CAP Update would not generate new or increased demand for fire protection services or interfere
with or modify the ability of police and fire protection services to meet performance objectives or
response times outlined in the 2024 SEIR. The CAP Update does not include development of new
residences or the creation of substantial numbers of permanent jobs requiring increased fire or police
services. The CAP Update would not induce population growth in the community that would require
school services, new or expanded park facilities, other public facilities. The measures and actions from
the CAP Update would not generate increased demand for public services such that construction of
new or expanded facilities would be required to maintain adequate service ratios. Therefore,
implementation of the CAP Update would not result in substantial adverse physical impacts associated
with the provision of new or physically altered governmental facilities.
Conclusion
There are no changes in circumstances or new information of substantial importance that would
require major revisions to the 2024 SEIR or result in new significant effects or a substantial increase in
the severity of previously identified effects related to public services. The 2024 SEIR did not identify
significant public services impacts and did not identify mitigation measures. The CAP Update would
not result in any new or substantially more severe significant impacts related to public services. Applicable Mitigation Measures from the SEIR
There are no mitigation measures from the 2024 SEIR identified to reduce impacts related to public

Previous CEQA Analysis Recreation Findings
The 2024 SEIR identified less than significant impacts associated with the provision of new or physically
altered parks, or the need for new or physically altered parks, the construction of which could cause
significant environmental impacts, in order to maintain acceptable service ratios or other performance
objectives (PS-4). The 2024 SEIR identified less than significant impacts related to the increase in use
of existing neighborhood and regional parks or other recreational facilities such that substantial
physical deterioration of the facility would occur or be accelerated and for including recreational
facilities or requiring the construction or expansion of recreational facilities which might have an
adverse physical effect on the environment (PS-4) (Section 4.12, Public Services and Recreation).
Addendum Analysis
The CAP Update would not generate new or increased demand for parks and recreation facilities.
Typically, this impact occurs when a project induces population growth, such as new development or
a business that would necessitate a large number of new employees. The CAP Update does not include
development of new residences or the creation of substantial numbers of permanent jobs. Therefore,
implementation of the CAP Update would not result in substantial adverse physical impacts associated
with the provision of new or physically altered park facilities. Implementation of the CAP Update would
also not increase the use of recreational facilities to the extent that substantial deterioration would
occur or require the construction or expansion of recreational facilities.
Conclusion
There are no changes in circumstances or new information of substantial importance that would
require major revisions to the 2024 SEIR or result in new significant effects or a substantial increase in
the severity of previously identified effects related to recreation. The 2024 SEIR did not identify
significant recreation impacts and did not identify mitigation measures. The CAP Update would not
result in any new or substantially more severe significant impacts related to recreation. Applicable Mitigation Measures from the SEIR
There are no mitigation measures from the 2024 SEIR identified to reduce impacts related to

Previous CEQA Analysis Transportation Findings
The 2024 SEIR identified a less than significant impact for conflicts with a program, plan, ordinance or
policy addressing the circulation system, including transit, roadway, bicycle and pedestrian facilities
(T-1). The 2024 SEIR identified that although mitigation measure T-1 would aim to achieve VMT
reductions for development projects, it concluded impacts to be significant and unavoidable related
to CEQA Guidelines Section 15064.3, subdivision (b) (T-2). The 2024 SEIR identified a less than
significant impact related to substantially increasing hazards due to a geometric design feature (T-3)
and for inadequate emergency access (T-4) (Section 4.13, Transportation).
Addendum Analysis
Overall, implementation of the CAP Update (e.g., Measures T-1 through T-7 and T-10) would result in
lower total annual VMT levels in the city. However, short-term construction activities associated with
the CAP Update would lead to minor, temporary disruptions to traffic circulation patterns during the
period of construction. Projects that would require construction include retrofitting of existing
buildings and developments to transition to higher energy efficiency and renewable energy generation
(Measures E-1, E-6, W-1, and W-2), constructing roundabouts or traffic circles (Measure T-1),
installation of solar carports (Measure E-3.3), installation of zero emission vehicle charging stations
(Measure T-8), improvements to pedestrian and bicycling infrastructure (Measures T-5 and T-4), and
implementation of activities related to urban tree planting (Measure CS-1).
Long-term transportation changes could result from actions aimed at diverting and eliminating solid
waste; for example, generation of more compostable materials and demand for compost products
(Measure WD-1) would lead to a need for haul trucks to transport these materials. Truck trips for hauling
of organic waste to processing facilities would be offset by reductions in truck trips to landfills. Organic
waste collected in the city is recycled at a Republic Services composting facility in Otay (City of Carlsbad
2024). Other long-term transportation changes associated with the CAP Update could result from actions
that increase transit use and reduce commuting and traffic congestion. Actions such as increasing the
number of roundabouts or traffic circles (Measure T-1), and incentivizing people to use alternative modes
of travel (Measures T-2 and T-8) would lead to reduced traffic congestion. Changes to circulation patterns
for pedestrian and cycling mobility modes would result from implementation of new pedestrian and
bicycling routes, as well as enhancement of existing infrastructure (e.g., adding lanes, buffers, and
sidewalks). Implementation of the CAP Update would improve the operation of the circulation system in
several ways, including fewer vehicle trips on roadways and highways and higher numbers of transit
riders. Therefore, implementation of the CAP Update would not adversely affect the performance of the
circulation system and would not conflict with any applicable transportation plans, ordinances, or policies.
Implementation of the CAP Update would not induce substantial population or employment growth in
the city that would in turn generate increased VMT. Construction activities associated with the CAP
Update measures and actions would not require a large construction crew. Any temporary VMT
increases associated with construction activities would be more than offset by the CAP Update’s overall
effect of reducing the long-term rate of VMT in the city. Therefore, CAP Update implementation would
not conflict or be inconsistent with CEQA Guidelines section 15064.3(b). SEIR mitigation measure T-1,
which would reduce VMT levels of housing development identified in the SEIR, is not applicable to the
CAP Update because the CAP Update would result in decreased levels of VMT in the city.
The city maintains improvement standards that guide the construction of new transportation facilities
to minimize design hazards for all users of the system. Furthermore, General Plan policies 3-P.10, 3-
P.12, 3-P.13, and 3-P.16 would reduce impacts related to safety. Therefore, implementation of the
CAP Update would not substantially increase hazards due to a geometric design feature.

Addendum Evaluation
Addendum No. 1 Housing Element Implementation and Public Safety Element Update SEIR 75
In the short-term, implementation of the CAP Update would have the potential to affect emergency
access during construction of individual projects facilitated by the CAP Update. For example,
construction pertaining to improving pedestrian and bicycle infrastructure and safety (Measures T-4 and
T-5) could temporarily alter existing roadways that serve as emergency access routes. In the long-term,
the CAP Update would not result in new development or land uses that would require installation of
emergency access routes. Activities implementing the CAP Update would not be permitted to conflict
with regulatory requirements to provide adequate accommodation of fire access to structure frontages,
multiple access points to development, as well as adequate width, height, and turning radius of roadways
and access points, pursuant to California Building Code and California Fire Code requirements. Activities
implementing the CAP Update would be required to comply with city and San Diego County standards
and requirements and would undergo review by public safety officials as part of the approval process.
Additionally, General Plan policies 3-P.12, 3-P.29, 3-P.30, and 3-P.33 would prevent CAP update
implementation from resulting in physical effects that impede or obstruct emergency access. Therefore,
implementation of the CAP Update would not result in inadequate emergency access.
Conclusion
There are no changes in circumstances or new information of substantial importance that would
require major revisions to the 2024 SEIR or result in new significant effects or a substantial increase in
the severity of previously identified effects related to transportation. Implementation of Mitigation
Measure T-1 from the 2024 SEIR is not applicable to the CAP Update. The CAP Update would not result
in any new or substantially more severe significant impacts related to transportation. Applicable Mitigation Measures from the SEIR
The 2024 SEIR identified Mitigation Measure T-1 for transportation impact T-2. This mitigation
measure is not applicable to the CAP Update.

Previous CEQA Analysis Tribal Cultural Resources Findings
The 2024 SEIR identified less than significant impacts related to causing a substantial adverse change
in the significance of a Tribal cultural resource as defined in Public Resources Code Section 21074
that is listed or eligible for listing in the California Register of Historical Resources, or in a local
register of historical resources as defined in Public Resources Code Section 5020.1(k) or pursuant to
criteria set forth in subdivision (c) of Public Resources Code Section 5024.1 (CUL-4) (Section 4.4,
Cultural and Tribal Cultural Resources).
Addendum Analysis
Implementation of the CAP Update would result in physical changes to the environment that could
occur in proximity to or involve encountering tribal cultural resources. For example, some
improvements that result from the CAP Update, such as Measures T-1, T-4, T-5, T-8, T-9, CS-1, E-3.3, W-
1, and W-2, would require ground disturbing activities, including minor grading and excavation, during
which, depending on their location, a tribal cultural resource could be encountered. The Carlsbad
Cultural Resource Guidelines addresses identification and treatment of tribal cultural resources that
may be impacted as a result of the CAP Update. Therefore, implementation of the CAP Update would
not cause a substantial adverse change in the significance of a tribal cultural resource, defined in Public
Resources Code section 21074 as either a site, feature, place, cultural landscape that is geographically
defined in terms of the size and scope of the landscape, sacred place, or object with cultural value to a
California Native American tribe, and that is listed or eligible for listing in the California Register of
Historical Resources, or in a local register of historical resources as defined in Public Resources Code
section 5020.1(k). Since the CAP Update would adhere to the Carlsbad Cultural Resource Guidelines, it
would not cause a substantial adverse change in the significance of a tribal cultural resource, pursuant
to criteria set forth in subdivision (c) of Public Resources Code §5024.1.
Conclusion
There are no changes in circumstances or new information of substantial importance that would
require major revisions to the 2024 SEIR or result in new significant effects or a substantial increase in
the severity of previously identified effects related to tribal cultural resources. The 2024 SEIR did not
identify significant tribal cultural resources impacts and did not identify mitigation measures. The CAP
Update would not result in any new or substantially more severe significant impacts related to tribal
cultural resources. Applicable Mitigation Measures from the SEIR
There are no mitigation measures from the 2024 SEIR identified to reduce impacts related to tribal
cultural resources.

Previous CEQA Analysis Utilities and Service Systems Findings
The 2024 SEIR identified less than significant impacts related to the relocation or construction of new
or expanded water, wastewater treatment or stormwater drainage, electric power, natural gas, or
telecommunication facilities (UTIL-1); sufficient water supplies during normal, dry and multiple dry
years (UTIL-2); adequate wastewater treatment capacity (UTIL-3); the generation of solid waste in
excess of State or local standards, or in excess of the capacity of local infrastructure, or otherwise
impair the attainment of solid waste reduction goals and compliance with federal, State, and local
management and reduction statutes and regulations related to solid waste (UTIL-4) (Section 4.14,
Utilities and Service Systems).
Addendum Analysis
Implementation of the CAP Update would not increase development or induce population growth
directly or indirectly, because measures and actions do not propose new housing nor do they propose
changes to policies or regulations related to land use or residential or nonresidential zoning. Although
tree planting (Measure CS-1) would potentially increase demand for water used for irrigation, the CAP
Update would be required to comply with General Plan policies 9-P.3 through 9-P.6, which would
reduce impacts to water services and facilities by promoting water saving measures such as water sub-
metering, using recycled water for landscape irrigation, and using on-site gray water and rainwater
collection systems. Therefore, the CAP Update would not result in demand for new or expanded
infrastructure, including water, wastewater treatment, stormwater drainage, natural gas or
telecommunication facilities would not increase to serve new population or development.
The implementation of the CAP Update would incrementally increase electricity consumption, for
example through measures that increase the installation zero emission infrastructure (Measure T-8),
consume energy more efficiently within buildings and water systems (Measures E-3.1, E-3.2, E-4.2 E-
6, and W-2), and install solar carports (Measure E-3.3). However, as discussed in the San Diego Gas and
Electric Company (SDG&E)’s Integrated Resource Plan, SDG&E has existing plans in place to solicit
additional long-term renewable contracts, including conventional and long-duration storage
technologies (SDG&E 2022). The CAP Update’s support for using more renewable energy and more
efficient natural gas consumption would decrease demand for natural gas infrastructure.
The implementation of the CAP Update would not involve development of residential communities or
other non-residential development or induce population growth in an area that would increase
demand for wastewater treatment. Further, it would not involve the construction of restroom
facilities. Implementation of the CAP Update would not result in new habitable structures (e.g.,
housing, nonresidential development) that would generate wastewater, therefore, implementation of
the CAP Update would not exceed the capacity of any wastewater treatment provider.
Implementation of the CAP Update would not induce increased residential or non-residential
development, or population growth directly or indirectly, and there would be no increase in solid
waste production as a result of the CAP Update. Although some solid waste could be generated during
construction activities or through retrofitting buildings (Measure E-6), the solid waste generated
would be minimal due to the nature of construction activities and associated improvements, and
therefore would not exceed the capacity of local facilities. Measure WD-1 includes strategies to
continue to increase the diversion of waste from landfills, which is consistent with and would further
State solid waste statutes and goals Therefore, solid waste generated as a result of the CAP Update
would not be generated in excess of local standards or capacity of local infrastructure.

Addendum 85
Previous CEQA Analysis Wildfire Findings
The 2024 SEIR identified less than significant impacts for wildfire emergency response, access, and
evacuation (WF-1); and related to slope, prevailing winds, and other factors that could exacerbate
wildfire risks, installation or maintenance of associated infrastructure that may exacerbate fire risk or
that may result in temporary or ongoing impacts to the environment, exposing people or structures to significant risks, including downslope or downstream flooding or landslides, as a result of runoff, post-
fire slope instability, or drainage changes; and exposing people or structures, either directly or indirectly,
to a significant risk of loss, injury, or death involving wildland fires (WF-2) (Section 4.15, Wildfire).
Addendum Analysis
The implementation of the CAP Update would result in short-term and long-term changes related to wildfire as described below.
Implementation of the CAP Update would result in alterations of public roadways. The CAP Update measures and actions would include improvements at or near grade level of existing roadways, new and upgraded bikeways and walkways along existing developed roadways and rights-of-way in the city, and the installation of roundabouts or traffic circles to control traffic within the intersections of existing developed roadways (through implementation of Measures T-1, T-4, T-5, and T-8). However, these improvements would not adversely affect the capacity of roadways during an emergency or evacuation. New Class II bike lanes and Class II buffered bike plans implemented per Measure T-4
would be separately from vehicle lanes using paint and therefore would not impede the movement of emergency vehicles or vehicles during an evacuation event. CAP Update Measure T-1, which encourages the installation of roundabouts, would reduce congestion, thus increasing traffic flow and
the ability to evacuate during an emergency. Therefore, implementation of the CAP Update would not impair or interfere with adopted emergency response or evacuation plans.
Although the city is located within a Local Responsibly Area Very High Fire Hazard Severity Zone and
adjacent to a State Responsibility Area Very High Fire Hazard Severity Zone, the CAP Update measures and actions would not include the construction of new housing and do not propose changes to policies or regulations related to land use or residential zoning. The CAP Update would not introduce new
occupants that could be exposed to pollutant concentrations from a wildfire or the uncontrolled spread of as wildfire or require the installation or maintenance of associated infrastructure (such as roads, fuel brakes, emergency water sources, power lines or other utilities). Action CS-1.a would
continue implementation of the existing Community Forest Management Plan and therefore the CAP Update would not result in changes to the types of trees planted within fire hazard severity zones. Furthermore, activities associated with implementation of the CAP Update measures would comply
with the San Diego County Emergency Operations Plan (EOP) and be subject to the California Fire Code (CFC), which includes safety measures to minimize the threat of fire. Implementation of the CAP Update would also be required, where applicable, to meet CBC requirements, including CCR Title 24,
Part 2, which includes specific requirements related to exterior wildfire exposure. Impacts related to downslope or downstream flooding or landslides, as a result of runoff, post-fire slope instability, or drainage changes would be reduced by compliance with the CBC and CMC, as well as applicable
policies from the Public Safety Element Update (policies 6-P.20 through 6-P.31). Compliance with applicable policies, codes and regulations would reduce the risk of loss, injury, or death from wildfire and the CAP Update would not exacerbate wildfire risks.
