Air Quality Impact Analysis Memorandum for the LEGOLAND California 2025
Project in Carlsbad, California (LSA Project No. 20231502)
INTRODUCTION
LSA has prepared this Air Quality Impact Analysis Memorandum to evaluate potential impacts
associated with construction and operation of the proposed LEGOLAND California 2025 Project
(project) in Carlsbad, California. This analysis follows the methodology identified by the San Diego
County Air Pollution Control District (SDAPCD)1. This analysis includes an assessment of criteria
pollutant emissions, an assessment of carbon monoxide (CO) hot-spot impacts, and an assessment
of the project’s impact on sensitive receptors.
PROJECT LOCATION
The 2.38-acre project site is located within the Legoland Theme Park Carlsbad, in San Diego County,
California, at the site of the existing “Driving School” and “Junior Driving School” attractions, which
would be removed. The site is approximately 103,470 square feet (sq ft) (2.38 acres) in size with a
generally flat topography. Local access to the project site is provided by Legoland Drive and
Crossings Drive. The project location is shown in Figure 1 (all figures are provided in Attachment A).
PROJECT DESCRIPTION
The new attraction area would have a “space” theme where park guests would train for space
exploration, meet other intergalactic travelers, and blast off on missions into the LEGO Galaxy!
The proposed project would demolish the existing “Driving School” and “Junior Driving School”
attractions and redevelop the site with a new attraction called “Project Mars.” Existing site
development to be removed includes the driving school courses, queues, shade covers, a small retail

facility, and landscaping. Figure 2 illustrates the project site plan. The major components of the
proposed project are as follows:
• Primary Ride: The ride consists of an indoor roller coaster housed inside a new single-story,
32,319 sq ft, 44-foot-high pre-manufactured steel building. Ancillary uses within the building
include the ride queue, a LEGO brick building attraction, retail, and maintenance, as well as
mechanical and storage spaces.
• Secondary Ride: This ride has three cantilever arms that are lifted in the air by hydraulic
actuators and carry a counter-rotating gyro element holding four gondolas at each end. The
gondolas are designed to accommodate two riders to provide a capacity of up to 24 passengers.
• A Playscape: This would be an approximately 1,755 sq ft exterior area featuring a children’s play
structure with an alien spaceship theme.
• A Toddler Play Area (“Tot Spot”): The project also includes an approximately 1,234 sq ft exterior
area designed for the smallest guests, with LEGO DUPLO play features, shade cover, and seating.
Proposed site development will include grading, utilities, new hardscape, planting, and
retrofitting of existing recycled water irrigation systems.
In addition, landscape would be installed throughout the project site and would consist of
approximately 20,721 sq ft. The proposed project would utilize 100 percent recycled water for
irrigation, and all plant species would be in the low to moderate water use category. The proposed
project would be all electric and would not utilize natural gas for construction or operation.
Construction would include demolition, site preparation, grading, and building construction
activities. Construction of the proposed project is anticipated to commence in January 2024 and end
in March 2025. The project would demolish approximately 811 sq ft of the existing attractions.
Based on the preliminary grading plans, the project would require approximately 4,476 cubic yards
of soil cut, 1,236 cubic yards of fill, for a net total of approximately 3,240 cubic yards of export.
Demolition, grading, and building activities would involve the use of standard earthmoving
equipment such as large excavators, cranes, and other related equipment. In addition, the proposed
project would utilize Tier 2 construction equipment.
EXISTING LAND USES IN THE PROJECT AREA
For the purposes of this analysis, sensitive receptors are areas of the population that have an
increased sensitivity to air pollution or environmental contaminants. Sensitive receptor locations
include residences, schools, daycare centers, hospitals, parks, and similar uses that are sensitive to
air quality. Impacts on sensitive receptors are of particular concern because those receptors are the
population most vulnerable to the effects of air pollution. The project site is surrounded by a
business park to the west across Legoland Drive and the existing theme park immediately to the
north, east, and south. The closest sensitive receptor to the project site includes single-family
residential uses located approximately 2,900 feet to the south.

ENVIRONMENTAL SETTING
Air quality is primarily a function of both local climate and local sources of air pollution and regional
pollution transport. The amount of a given pollutant in the atmosphere is determined by the
amount of the pollutant released and the atmosphere’s ability to transport and dilute the pollutant.
The major determinants of transport and dilution are wind, atmospheric stability, and terrain, and
for photochemical pollutants, sunshine.
A region’s topographic features have a direct correlation with air pollution flow and, therefore, are
used to determine the boundary of air basins. The proposed project is located in the City of Carlsbad
(City) within the jurisdiction of the SDAPCD, which regulates air quality in the San Diego Air Basin
(SDAB).
The SDAB experiences a persistent temperature inversion (increasing temperature with increasing
altitude) as a result of the Pacific high. This inversion limits the vertical dispersion of air
contaminants, holding them relatively near the ground. As the sun warms the ground and the lower
air layer, the temperature of the lower air layer approaches the temperature of the base of the
inversion (upper) layer until the inversion layer finally breaks, allowing vertical mixing with the lower
layer. This phenomenon is observed in midafternoon to late afternoon on hot summer days when
the air appears to clear up suddenly. Winter inversions frequently break by midmorning.
Winds in the project area blow predominantly from the south-southwest, with relatively low
velocities. Wind speeds in the project area average about 5 miles per hour. Summer wind speeds
average slightly higher than winter wind speeds. Low average wind speeds, together with a persistent
temperature inversion, limit the vertical dispersion of air pollutants throughout the SDAB. Strong, dry,
north or northeasterly winds, known as Santa Ana winds, occur during the fall and winter months,
dispersing air contaminants. The Santa Ana conditions tend to last for several days at a time.
The combination of stagnant wind conditions and low inversions produces the greatest pollutant
concentrations. On days of no inversion or high wind speeds, ambient air pollutant concentrations
are the lowest. During periods of low inversions and low wind speeds, air pollutants generated in
urbanized areas are transported predominantly onshore into Riverside and San Bernardino
Counties. In the winter, the greatest pollution problems are CO and nitrogen oxides (NOX) because
of extremely low inversions and air stagnation during the night and early morning hours. In the
summer, the longer daylight hours and brighter sunshine combine to cause a reaction between
hydrocarbons and NOX to form photochemical smog. Smog is a general term for naturally occurring
fog that has become mixed with smoke or pollution. In this context, it is better described as a form
of air pollution produced by the photochemical reaction of sunlight with pollutants that have been
released into the atmosphere, especially by automotive emissions.
Attainment Status
Both the State of California (State) and the federal government have established health-based
Ambient Air Quality Standards (AAQS) for six criteria air pollutants: carbon monoxide (CO), ozone
(O3), nitrogen dioxide (NO2), sulfur dioxide (SO2), lead (Pb), and suspended particulate matter (PM2.5
and PM10). The SDAB is designated as nonattainment for O3 for federal standards and
nonattainment for O3, PM10, and PM2.5 for State standards.
8/1/23 (P:\20231502-Legoland Mars Attraction\Product\AQ\Legoland California 2025 Project - AQ memo.docx) 4
Air quality monitoring stations are located throughout the nation and maintained by the local air
districts and State air quality regulating agencies. Data collected at permanent monitoring stations
are used by the United States Environmental Protection Agency (USEPA) to identify regions as
“attainment” or “nonattainment” depending on whether the regions meet the requirements stated
in the applicable National Air Quality Standards (NAAQS). Nonattainment areas are imposed with
additional restrictions as required by the USEPA. In addition, different classifications of attainment,
such as marginal, moderate, serious, severe, and extreme, are used to classify each air basin in the
State on a pollutant-by-pollutant basis. The classifications are used as a foundation to create air
quality management strategies to improve air quality and comply with the NAAQS. Attainment
statuses for each of the criteria pollutants for San Diego County are listed in Table A.

Air Quality Monitoring Results
Air quality monitoring stations are located throughout the nation and are maintained by the local air
pollution control district and State air quality regulating agencies. The SDAPCD, together with the
California Air Resources Board (CARB), maintains ambient air quality monitoring stations in the
SDAB. The air quality monitoring station closest to the project area is the Camp Pendleton ambient
air quality monitoring station in Oceanside. The air quality trends from this station are used to
represent the ambient air quality in the project area. Ambient air quality in the project area from
2020 to 2022 is shown in Table B. CO, PM2.5, PM10, and SO2 are not monitored at the Camp
Pendleton station; therefore, Table B includes PM2.5, PM10, SO2, and CO data from the 533 First

Street monitoring station in El Cajon.2 As indicated in the monitoring results, no violations of the
federal and State PM10 standard occurred during the 3-year period. PM2.5 levels exceeded the
federal standard 2 times in 2020 only. The State 1-hour O3 standard was not exceeded in 2020, but
no data were available for 2021 or 2022. Additionally, the federal and State 8-hour O3 standards
were not exceeded during the 3-year period. The CO, SO2, and NO2 standards were not exceeded.
REGULATORY SETTING
Applicable federal, State, regional, and local air quality regulations are discussed below.
Federal Regulations
The 1970 federal Clean Air Act (CAA) authorized the establishment of national health-based air
quality standards and set deadlines for their attainment. The CAA Amendments of 1990 changed
deadlines for attaining national standards as well as the remedial actions required for areas of the
nation that exceed the standards. Under the CAA, State and local agencies in areas that exceed the
national standards are required to develop State Implementation Plans (SIPs) to demonstrate how
they will achieve the national standards by specified dates.
State Regulations
In 1988, the California Clean Air Act (CCAA) required that all air districts in the State endeavor to
achieve and maintain California Ambient Air Quality Standards (CAAQS) for CO, O3, SO2, and NO2 by
the earliest practical date. The CCAA provides districts with the authority to regulate indirect
sources and mandates that air quality districts focus particular attention on reducing emissions from
transportation and area-wide emission sources. Each nonattainment district is required to adopt a
plan to achieve a 5 percent annual reduction, averaged over consecutive 3-year periods, in district-
wide emissions of each nonattainment pollutant or its precursors. A Clean Air Plan shows how a
district would reduce emissions to achieve air quality standards. Generally, the State standards for
these pollutants are more stringent than the national standards.
The CARB is the State’s “clean air agency.” The CARB’s goals are to attain and maintain healthy air
quality, protect the public from exposure to toxic air contaminants, and oversee compliance with air
pollution rules and regulations.
Regional Regulations
San Diego County Air Pollution Control District. The SDAPCD has adopted air quality plans to
improve air quality, protect public health, and protect the climate. The San Diego Regional Air
Quality Strategy (RAQS) outlines SDAPCD plans and control measures designed to attain and
maintain the State standards, while San Diego’s portions of the SIP are designed to attain and
maintain federal standards. The RAQS was initially adopted in 1991 and is updated on a triennial
basis. The RAQS was updated in 1995, 1998, 2001, 2004, 2009, 2016, and most recently in
December 2022. The RAQS does not currently address the CAAQS for PM2.5 and PM10.

8/1/23 (P:\20231502-Legoland Mars Attraction\Product\AQ\Legoland California 2025 Project - AQ memo.docx) 7
SDAPCD has also developed the SDAB input to the SIP, which is required under the CAA for areas
that are out of attainment of air quality standards. Both the RAQS and SIP demonstrate the
effectiveness of CARB measures (mainly for mobile sources) and SDAPCD plans and control
measures (mainly for stationary and area-wide sources) for attaining the O3 NAAQS. The SIP is also
updated on a triennial basis. SDAPCD adopted its attainment plan and Reasonable Available Control
Technology Demonstration for the 2008 8-hour O3 NAAQS. In addition, the Measures to Reduce
Particulate Matter in San Diego County Report3 proposes measures to reduce particulate matter
emissions and recommends measures for further detailed evaluation and, if appropriate, future rule
development (or non-regulatory development, if applicable), adoption, and implementation in San
Diego County, in order to attain particulate matter CAAQS.
The RAQS relies on information from the CARB and the San Diego Association of Governments
(SANDAG), including mobile and area source emissions, as well as information regarding projected
growth in the County, to project future emissions and then determine from that the strategies
necessary for the reduction of emissions through regulatory controls. The CARB mobile source
emission projections and SANDAG growth projections are based on population and vehicle trends
and land use plans developed by the cities and by the County as part of the development of the
County’s General Plan. As such, projects that propose development that is consistent with the
growth anticipated by the General Plans would be consistent with the RAQS. In the event that a
project would propose development that is less dense than anticipated by the County’s General
Plan, the project would likewise be consistent with the RAQS. If a project proposes development
that is greater than that anticipated by the General Plan and SANDAG growth projections, the
project might be in conflict with the RAQS and SIP, and might have a potentially significant impact
on air quality.
The SIP relies on the same information from SANDAG to develop emission inventories and emission
reduction strategies that are included in the attainment demonstration for the SDAB. The SIP also
includes rules and regulations that have been adopted by the SDAPCD to control emissions from
stationary sources. These SIP-approved rules may be used as a guideline to determine whether a
project’s emissions would have the potential to conflict with the SIP and thereby hinder attainment
of the NAAQS for ozone.
SDAPCD Rules and Regulations. As stated above, the SDAPCD is responsible for planning,
implementing, and enforcing NAAQS and CAAQS in the SDAB. The following rules and regulations
apply to all sources within the jurisdiction of SDAPCD, and would apply to the proposed project:
1. SDAPCD Regulation IV: Prohibitions; Rule 50: Visible Emissions. Prohibits visible emissions from
exceeding a determined visual threshold from being emitted, this rule applies to the discharge
of any air contaminant other than uncombined water vapor.4

manufacturers, distributors, and end users of architectural and industrial maintenance coatings
to reduce volatile organic compound (VOC) emissions from the use of these coatings, primarily
by placing limits on the VOC content of various coating categories.7
San Diego Association of Governments. The SANDAG adopted the San Diego Forward: The 2021
Federal Regional Transportation Plan (2021 Regional Plan), which serves as the long-term blueprint
for the San Diego region that seeks to meet regulatory requirements, address traffic congestion, and
create equal access to jobs, education, healthcare, and other community resources. The 2021
Regional Plan considers climate action planning, climate adaptation, curb management, electric
vehicles, fix it first, housing, land use and regional growth, parking management, pricing,
transportation demand management, transportation system management and operations, and
vision zero.8

• Policy 4-P.56 Ensure that construction and grading projects minimize short-term impacts to air
quality.
○ Require grading projects to provide a storm water pollution prevention plan (SWPPP) in
compliance with City requirements, which include standards for best management practices
that control pollutants from dust generated by construction activities and those related to
vehicle and equipment cleaning, fueling, and maintenance.
○ Require grading projects to undertake measures to minimize mono-nitrogen oxides (NOX)
emissions from vehicle and equipment operations.
○ Monitor all construction to ensure that proper steps are implemented.
METHODOLOGY
Construction Emissions
Construction activities can generate a substantial amount of air pollution. Construction activities are
considered temporary; however, short-term impacts can contribute to exceedances of air quality
standards. Construction activities include demolition, site preparation, earthmoving, and general
construction. The emissions generated from these common construction activities include: fugitive
dust from soil disturbance; fuel combustion from mobile heavy-duty; diesel- and gasoline-powered
equipment; portable auxiliary equipment; and worker commute trips.
The California Emissions Estimator Model version 2022.1 (CalEEMod) computer program was used
to calculate emissions from on-site construction equipment and emissions from worker and vehicle
trips to the site. As described above, the project would demolish approximately 811 sq ft of the
existing park attractions to construct the “Project Mars” new theme park attraction, which was
included in CalEEMod. This analysis assumes that construction would begin in January 2024 and end
in March 2025, which was also included in CalEEMod. Based on the preliminary grading plans, the
project would require a net total of approximately 3,240 cubic yards of soil export, which was
included in CalEEMod. Demolition, grading, and building activities would involve the use of standard
earthmoving equipment such as large excavators, cranes, and other related equipment. All other
construction details are not yet known; therefore, default assumptions (e.g., construction duration,
construction worker and truck trips and fleet activities) from CalEEMod were used. This analysis also
assumes the use of Tier 2 construction equipment as allowed for under the CARB in-use off-road
diesel fueled fleets regulation.
Operational Emissions
This air quality analysis includes estimating emissions associated with long-term operation of the
project. Indirect emissions of criteria pollutants with regional impacts would be emitted by project-
generated vehicle trips. In addition, localized air quality impacts (i.e., higher carbon monoxide
concentrations or “hot-spots”) near intersections or roadway segments in the project vicinity would
also potentially occur due to project-generated vehicle trips.
8/1/23 (P:\20231502-Legoland Mars Attraction\Product\AQ\Legoland California 2025 Project - AQ memo.docx) 10
Consistent with SDAPCD guidance for estimating emissions associated with land use development
projects, the CalEEMod computer program was used to calculate the long-term operational
emissions associated with the project. As discussed previously in the Project Description section, the
proposed project would construct an inside roller coaster and associated ancillary uses. CalEEMod
does not have specific land use codes for amusement parks. As such, the analysis was conducted
using the land use codes General Light Industry and Parking Lot to generally reflect the proposed
project. The proposed project would replace the existing attractions with a new attraction;
therefore, the proposed project would not generate new vehicle trips, which was assumed in
CalEEMod.
THRESHOLDS OF SIGNIFICANCE
The State CEQA Guidelines indicate that a project would normally have a significant adverse air
quality impact if project-generated pollutant emissions would do any of the following:
• Conflict with or obstruct implementation of the applicable air quality plan;
• Result in a cumulatively considerable net increase of any criteria pollutant for which the project
is nonattainment under applicable federal or State ambient air quality standards;
• Expose sensitive receptors to substantial pollutant concentrations; or
• Result in other emissions (such as those leading to odors) affecting a substantial number of
people.
Appendix G of the State CEQA Guidelines indicates that, where available, the significance criteria
established by the applicable air quality management district or air pollution control district may be
relied upon to determine whether a project would have a significant impact on air quality.
Regional Emissions Thresholds
The SDAPCD does not provide quantitative thresholds for determining the significance of
construction or mobile source-related impacts. However, the district does specify Air Quality Impact
Analysis (AQIA) trigger levels for new or modified stationary sources (SDAPCD Rules 20.2 and 20.3).
If these incremental levels for stationary sources are exceeded, an AQIA must be performed for the
proposed new or modified source. Although these trigger levels do not generally apply to mobile
sources or general land development projects, for comparative purposes, these levels may be used
to evaluate the increased emissions which would be discharged to the SDAB from proposed land
development projects.
For CEQA purposes, the screening criteria can be used as numeric methods to demonstrate that the
project’s total emissions (e.g., stationary and fugitive emissions, as well as emissions from mobile
sources) would not result in a significant impact to air quality. The hourly and yearly screening-level
thresholds are most appropriately used in situations when temporary emissions like emergency
generators or other stationary sources are proposed as a part of a project. The daily screening-level
thresholds are most appropriately used for the standard construction and operational emissions. As
8/1/23 (P:\20231502-Legoland Mars Attraction\Product\AQ\Legoland California 2025 Project - AQ memo.docx) 11
such, this analysis will compare the proposed project’s emissions to the daily screening-level
thresholds in Table C below.

the vicinity of the project are above or below State and federal CO standards. Because ambient CO
levels are below the standards throughout the SDAB, a project would be considered to have a
significant CO impact if project emissions result in an exceedance of one or more of the 1-hour or
8-hour standards. The following are applicable local emission concentration standards for CO:
• California State 1-hour CO standard of 20 parts per million (ppm)
• California State 8-hour CO standard of 9 ppm
IMPACT ANALYSIS
This section identifies potential air quality impacts associated with implementation of the proposed
project.
Consistency with Applicable Air Quality Plans
The SDAPCD is responsible for developing and implementing the clean air plans for attainment and
maintenance of the AAQS in the SDAPCD specifically, the SIP and RAQS. The federal O3 maintenance
plan, which is part of the SIP, was adopted in 2012. The most recent O3 attainment plan was
adopted in 2020. The SIP includes a demonstration that current strategies and tactics will maintain
acceptable air quality in the SDAB based on the NAAQS. The RAQS was initially adopted in 1991 and
is updated on a triennial basis (most recently in 2022). The RAQS outlines SDAPCD plans and control
measures designed to attain the State’s air quality standards for O3. The SIP and RAQS rely on
information from CARB and SANDAG, including mobile and area source emissions, as well as
information regarding projected growth in the County as a whole and the cities in the County, to
project future emissions and determine the strategies necessary for the reduction of emissions
through regulatory controls. CARB mobile source emission projections and SANDAG growth
8/1/23 (P:\20231502-Legoland Mars Attraction\Product\AQ\Legoland California 2025 Project - AQ memo.docx) 12
projections are based on population, vehicle trends, and land use plans developed by the County
and the cities in the County as part of the development of their general plans.
As discussed above, projects that propose development that is consistent with the growth
anticipated by the General Plans would be consistent with the RAQS. In the event that a project
would propose development that is less dense than anticipated by the General Plan, the project
would likewise be consistent with the RAQS. If a project proposes development that is greater than
that anticipated by the General Plan and SANDAG growth projections, the project might be in
conflict with the RAQS and SIP, and might have a potentially significant impact on air quality.
The proposed project would replace the two existing attractions with a new indoor rollercoaster. As
such, the proposed project would not result in development in excess of that anticipated in the
General Plan or increases in population/housing growth beyond those contemplated by SANDAG. As
such, the proposed project would not increase the population, vehicle trips, or vehicle miles
traveled beyond that anticipated in the RAQS and SIP. Because the proposed project activities and
associated vehicle trips are anticipated in local air quality plans, the proposed project would be
consistent at a regional level with the underlying growth forecasts in the RAQS and SIP.
Criteria Pollutant Analysis
The SDAB is currently designated nonattainment for O3, PM10, and PM2.5 standards. The SDAB
nonattainment status is attributed to the region’s development history. Past, present, and future
development projects contribute to the region’s adverse air quality impacts on a cumulative basis.
By its very nature, air pollution is largely a cumulative impact. No single project is sufficient in size
to, by itself, result in nonattainment of an ambient air quality standard. Instead, a project’s
individual emissions contribute to existing cumulatively significant adverse air quality impacts. If a
project’s contribution to the cumulative impact is considerable, then the project’s impact on air
quality would be considered significant.
In developing thresholds of significance for air pollutants, SDAPCD considered the emission levels for
which a project’s individual emissions would be cumulatively considerable. If a project exceeds the
identified significance thresholds, its emissions would be cumulatively considerable, resulting in
significant adverse air quality impacts to the region’s existing air quality conditions. Therefore,
additional analysis to assess cumulative impacts is not necessary. The following analysis assesses the
potential project-level air quality impacts associated with construction and operation of the
proposed project.
Construction Emissions. During construction, short-term degradation of air quality may occur due to
the release of particulate matter emissions (i.e., fugitive dust) generated by demolition, grading,
building construction, paving, and other activities. Emissions from construction equipment are also
anticipated and would include CO, NOx, VOC, directly emitted PM2.5 or PM10, and toxic air
contaminants such as diesel exhaust particulate matter.
Project construction activities would include demolition, grading, site preparation, building
construction, architectural coating, and paving activities. Construction-related effects on air quality
from the proposed project would be greatest during the site preparation phase due to the
8/1/23 (P:\20231502-Legoland Mars Attraction\Product\AQ\Legoland California 2025 Project - AQ memo.docx) 13
disturbance of soils. If not properly controlled, these activities would temporarily generate
particulate emissions. Sources of fugitive dust would include disturbed soils at the construction site.
Unless properly controlled, vehicles leaving the site would deposit dirt and mud on local streets,
which could be an additional source of airborne dust after it dries. PM10 emissions would vary from
day to day, depending on the nature and magnitude of construction activity and local weather
conditions. PM10 emissions would depend on soil moisture, silt content of soil, wind speed, and
amount of operating equipment. Larger dust particles would settle near the source, whereas fine
particles would be dispersed over greater distances from the construction site.
Water or other soil stabilizers can be used to control dust, resulting in emission reductions of
50 percent or more. The SDAPCD has established Rule 55, Fugitive Dust Control, which would
require the applicant to implement measures that would reduce the amount of particulate matter
generated during the construction period.10
In addition to dust-related PM10 emissions, heavy trucks and construction equipment powered by
gasoline and diesel engines would generate CO, sulfur oxides (SOx), NOx, VOC, and some soot
particulate (PM2.5 and PM10) in exhaust emissions. If construction activities were to increase traffic
congestion in the area, CO and other emissions from traffic would increase slightly while those
vehicles idle in traffic. These emissions would be temporary in nature and limited to the immediate
area surrounding the construction site.
Construction emissions were estimated for the project using CalEEMod and summarized in Table D.

The results shown in Table D indicate the proposed project would not exceed the significance
criteria for daily VOC, NOx, CO, SOx, PM10, or PM2.5 emissions. Therefore, construction of the
proposed project would not result in a cumulatively considerable net increase of any criteria
pollutant for which the project region is in nonattainment under an applicable federal or State
AAQS.

Operational Air Quality Impacts. Long-term air pollutant emissions associated typically include
emissions from area, energy, and mobile sources.
PM10 emissions result from running exhaust, tire and brake wear, and the entrainment of dust into
the atmosphere from vehicles traveling on paved roadways. Entrainment of PM10 occurs when
vehicle tires pulverize small rocks and pavement and the vehicle wakes generate airborne dust. The
contribution of tire and brake wear is small compared to the other particulate matter emission
processes. Gasoline-powered engines have small rates of particulate matter emissions compared
with diesel-powered vehicles. As discussed above, the proposed project would not generate any net
new vehicle trips; therefore, the proposed project would not result in mobile source emissions.
Energy-source emissions result from activities in buildings that use natural gas. The quantity of
emissions is the product of usage intensity (i.e., the amount of natural gas) and the emission factor
of the fuel source. The emission factor is determined by the fuel source, with cleaner energy
sources, like renewable energy, producing fewer emissions than conventional sources. As
mentioned above, the proposed project would be all-electric and would not utilize natural gas for
operation of the proposed project.
Typically, area source emissions consist of direct sources of air emissions located at the project site,
including architectural coatings and the use of landscape maintenance equipment. Area source
emissions associated with the project would include emissions from the use of architectural
coatings, consumer products, and landscaping equipment. This analysis assumes that the proposed
project would not include any fire pumps or backup diesel generators.
Long-term operational emissions associated with the proposed project were calculated using
CalEEMod. Table E provides the proposed project’s estimated operational emissions. Attachment B
provides CalEEMod output sheets.
The results shown in Table E indicate the proposed project would not exceed the significance criteria
for daily VOC, NOx, CO, SOx, PM10, or PM2.5 emissions. Therefore, operation of the proposed project
would not result in a cumulatively considerable net increase of any criteria pollutant for which the
project region is in nonattainment under an applicable federal or State AAQS.

Long-Term Microscale (CO Hot Spot) Analysis. Vehicular trips associated with the proposed project
would contribute to congestion at intersections and along roadway segments in the vicinity of the
proposed project site. Localized air quality impacts would occur when emissions from vehicular
traffic increase as a result of the proposed project. The primary mobile-source pollutant of local
concern is CO, a direct function of vehicle idling time and, thus, of traffic flow conditions. CO
transport is extremely limited; under normal meteorological conditions, it disperses rapidly with
distance from the source. However, under certain extreme meteorological conditions, CO
concentrations near a congested roadway or intersection may reach unhealthful levels, affecting
local sensitive receptors (e.g., residents, schoolchildren, the elderly, and hospital patients).
Typically, high CO concentrations are associated with roadways or intersections operating at
unacceptable levels of service or with extremely high traffic volumes. In areas with high ambient
background CO concentrations, modeling is recommended to determine a project’s effect on local
CO levels.
An assessment of project-related impacts on localized ambient air quality requires that future
ambient air quality levels be projected. Existing CO concentrations in the immediate project vicinity
are not available. Ambient CO levels monitored at the El Cajon Monitoring Station located at 533
First Street (the closest station to the project site), showed a highest recorded 1-hour concentration
of 1.5 ppm (the State standard is 20 ppm) and a highest 8-hour concentration of 1.4 ppm (the State
standard is 9 ppm) from 2020 to 2022. The highest CO concentrations would normally occur during
peak traffic hours; hence, CO impacts calculated under peak traffic conditions represent a worst-
case analysis. Reduced speeds and vehicular congestion at intersections result in increased CO
emissions.
The proposed project is not expected to generate any net new vehicle trips during operation.
Therefore, CO concentrations are not expected to significantly increase as a result of the proposed
project. Therefore, given the extremely low level of CO concentrations in the project area and the
lack of traffic impacts at any intersections, project-related vehicles are not expected to result in CO
concentrations exceeding the State or federal CO standards. No CO hot spots would occur, and the
project would not result in any project-related impacts on CO concentrations.
Health Risk on Nearby Sensitive Receptors
Sensitive receptors are defined as people that have an increased sensitivity to air pollution or
environmental contaminants. Sensitive receptor locations include schools, parks and playgrounds,
daycare centers, nursing homes, hospitals, and residential dwelling units. The project site is
surrounded by a business park to the west across Legoland Drive and the existing theme park
immediately to the north, east, and south. The closest sensitive receptor to the project site includes
single-family residential uses located approximately 2,900 feet to the south.
Construction activities associated with the proposed project would generate airborne particulates
and fugitive dust, as well as a small quantity of pollutants associated with the use of construction
equipment (e.g., diesel-fueled vehicles and equipment) on a short-term basis. However, construc-
tion contractors would be required to implement measures to reduce or eliminate emissions by
following SDAPCD Rule 55, Fugitive Dust Control, which would require the applicant to implement
8/1/23 (P:\20231502-Legoland Mars Attraction\Product\AQ\Legoland California 2025 Project - AQ memo.docx) 16
measures that would reduce the amount of particulate matter generated during the construction
period. In addition, project construction emissions would be well below SDAPCD significance
thresholds. Once the project is constructed, the project would not be a source of substantial
pollutant emissions. Therefore, sensitive receptors are not expected to be exposed to substantial
pollutant concentrations during project construction and operation.
Odors
SDAPCD Rules 50, 51, and 55 require the project applicant to include implementation of standard
control measures for fugitive dust and diesel equipment emissions. Additionally, operators of off-
road vehicles (i.e., self-propelled diesel-fueled vehicles 25 horsepower and up that were not
designed to be driven on road) are required to limit vehicle idling to five minutes or less; register
and label vehicles in accordance with the CARB Diesel Off-Road Online Reporting System; restrict
the inclusion of older vehicles into fleets; and retire, replace, or repower older engines or install
Verified Diesel Emission Control Strategies (e.g., exhaust retrofits). Additionally, SDAPCD Rule 55
regarding nuisances states: “A person shall not discharge from any source whatsoever such
quantities of air contaminants or other material which cause injury, detriment, nuisance, or
annoyance to any considerable number of persons or to the public, or which endanger the comfort,
repose, health or safety of any such persons or the public, or which cause, or have a natural
tendency to cause injury or damage to business or property.”
During project construction, some odors may be present due to diesel exhaust. However, these
odors would be temporary and limited to the construction period. In addition, the proposed project
would be required to comply with SDAPCD nuisance and odor rules. The proposed project would not
include any activities or operations that would generate objectionable odors and once operational,
the project would not be a source of odors. Therefore, the proposed project would not result in
other emissions (such as those leading to odors) adversely affecting a substantial number of people.
CONCLUSION
Based on the analysis presented above, construction and operation of the proposed project would
not result in the generation of criteria air pollutants that would exceed SDAPCD thresholds and
mitigation measures are not required. Compliance with SDAPCD Rule 55: Fugitive Dust Control
would further reduce construction dust impacts. The project would also be consistent with the
applicable air quality plans. The proposed project is not expected to produce significant emissions
that would affect nearby sensitive receptors. The project would also not result in objectionable
odors affecting a substantial number of people. Therefore, the proposed project’s emissions would
be less than significant.
