FLEMING & SONS CONCRETE, INC. PUMPING TRUCK YARD

VEHICLE MILES TRAVELED (VMT) SCREENING EVALUATION
Urban Crossroads, Inc. is pleased to provide the following Vehicle Miles Traveled (VMT) Screening Evaluation for the proposed Fleming & Sons Concrete, Inc.

Pumping Truck Yard ( Project), which is located at south west corner of the intersection of West Minthorn and North Riley in the City of Lake Elsinore.

PROJECT OVERVIEW
It is our understanding that the Project is to consist of a concrete pumping truck parking yard, minor maintenance, and administrative office building (7,500 square feet). The approximately 1.6-acre property is currently vacant.

A preliminary site plan for the proposed Project is found in Attachment A.

PROJECT OPERATIONAL CHARATERISTICS
The Project would provide for parking and maintenance of 10-12 concrete pump semi-trucks on site. Each day most will leave the yard and return. Trucks that are not working receive needed light duty maintenance such as tires, pipes, hoses, check and maintain fluids, fix mirror or windshield, etc. to be ready for use the following day. No major repair work is done on-site. Typical operations include the trucks exiting the yard and going directly to different jobsites each day, meet with concrete mixing trucks at the site and concrete is poured from the concrete trucks through the pumps to place concrete at the jobsite. Trucks will be washed out and cleaned off-site before returning to the yard. Trucks will also be re-fueled off-site.

Sales and parts ordering personnel will work out of the administrative office.

Typical operations will occur Monday through Friday (with occasional weekend operations) from 4:00 AM to 6:00 PM. There will be a pproximately 10 -12 employees on the site at any given time.

BACKGROUND
The California Environmental Quality Act (CEQA) requires all lead agencies to adopt VMT as the measure for identifying transportation impacts for land use projects.

To comply with CEQA, the City of Lake Elsinore adopted analytical procedures, screening tools, and impact thresholds for VMT, which are documented in the Traffic Impact Analysis Preparation Guide (Revised November 2022) (City Guidelines) (1).The City Guidelines were used to determine if the proposed Project can be screened from further VMT analysis.

VMT SCREENING
The City Guidelines provide details on appropriate screening criteria that can be used to identify when a proposed land use project is anticipated to result in a less than significant impact without conducting a more detailed project level analysis. To aid in the project -level VMT screening process, the City of Lake Elsinore utilizes the WRCOG VMT Screening Tool (Screening Tool). The web-based Screening Tool allows a user to select the Project’s parcel to determine if its location meets one or more of the land use screening criteria identified in the City Guidelines. The City of Lake Elsinore’s VMT screening steps as described within the City Guidelines are listed below and a land use project need only to meet one to result in a less than significant impact:
• Step 1: Transit Priority Area (TPA) Screening
• Step 2: Low VMT Area Screening
• Step 3: Project Type Screening
STEP 1: TPA SCREENING
Consistent with guidance identified in the City Guidelines, projects located within a Transit Priority Area (TPA) (i.e., within ½ mile of an existing “major transit stop”1 or an existing stop along a “high- quality transit corridor” 2) may be presumed to have a less than significant impact absent substantial evidence to the contrary.

However, the presumption may not be appropriate if a project:
• Has a Floor Area Ratio (FAR) of less than 0.75;
• Includes more parking for use by residents, customers, or employees of the project than required by the jurisdiction (if the jurisdiction requires the project to supply parking); • Is inconsistent with the applicable Sustainable Communities Strategy (as determined by the lead agency, with input from the Metropolitan Planning Organization); or • Replaces affordable residential units with a smaller number of moderate- or high-income residential units.

Based on the Screening Tool results, the Project is not located within a ½ mile of an existing major transit stop or an existing stop along a high-quality transit corridor. (See Attachment B) TPA Screening step is not met.

1 Pub. Resources Code, § 21064.3 (“‘Major transit stop’ means a site containing an existing rail transit station, a ferry terminal served by either a bus or rail transit service, or the intersection of two or more major bus routes with a frequency of service interval of 15 minutes or less during the morning and afternoon peak commute periods.”). 2 Pub. Resources Code, § 21155 (“For purposes of this section, a high-quality transit corridor means a corridor with fixed route bus service with service intervals no longer than 15 minutes during peak commute hours.”).

15715-01 VMT
STEP 2: LOW VMT AREA SCREENING
The City Guidelines state s that “ Residential and office projects located within a low VMT- generating area are presumed to have a less than significant impact absent substantial evidence to the contrary. In addition, other employment -related and mixed- use land use projects may qualify for the use of screening if the project can reasonably be expected to generate VMT per service population that is similar to the existing land uses in the low VMT area.” City Guidelines identifies low VMT generating traffic analysis zones as those that generate VMT per service population below the City of Lake Elsinore’s baseline3 VMT per service population.

The latest version of the Riverside County Transportation Model (RIVCOM) was used to determine the existing VMT per service population for TAZ 1025, where the Project is located. TAZ 1025 was found to generate 29.7 VMT per service population, which is below the City of Lake Elsinore's current citywide average VMT per service population of 35.5. The Project's proposed construction-related land use aligns with the existing land uses in TAZ 1025, such as construction and industrial employees, and is not anticipated introduce changes travel patterns in the area.

The Project is located in a low VMT -generating area based on VMT per service population.

Attachment B contains a screen shot of the Screening Tool output for the Project TAZ.

Low VMT Area Screening step is met.

STEP 3: PROJECT TYPE SCREENING
The City Guidelines identifies that local serving retail projects less than 50,000 square feet may be presumed to have a less than significant impact absent substantial evidence to the contrary.

In addition to local serving retail, other types of local serving use (e.g., local parks, local serving gas stations, non -destination hotels, affordable housing, places of worship, etc.) may also be presumed to have a less than significant impact as their uses are local serving in nature and would tend to shorten vehicle trips.
4 Based on the Project’s operational characteristics the Project does not lend itself to be considered a local serving use.

In addition, the City Guidelines states that small land use projects generating 110 or fewer daily vehicle trips are assumed to cause a less than significant impact on VMT.

TRIP GENERATION
Trip generation represents the amount of traffic which is both attracted to and produced by a development. Determining traffic generation for a specific project is therefore based upon forecasting the amount of traffic that is expected to be both attracted to and produced by the specific land uses being proposed for a given development.

In order to develop the traffic characteristics of the proposed Project, trip- generation statistics published in the Institute of Transportation Engineers (ITE) Trip Generation Manual (11th Edition, 2021) was used to estimate the trip generation. The latest Trip Generation Manual does not have

a land use category for the proposed storage yard for concrete pump trucks. As such, the following land use category has been selected from the Trip Generation Manual which closely estimates the anticipated traffic for the proposed Project:
• Th e trip generation rates for ITE land use code 180 (Specialty Trade Contractor) have been used to derive site specific trip generation estimates for the Project based on the total number of employees . In addition to the 10- 12 employees on site within the administrative offices, the calculations also assume an additional 12 drivers for the trucks (e.g., up to 24 employees). The vehicle mix has been obtained from the ITE’s Trip Generation Manual . All trucks are assumed to be 4+- axle in an effort to conduct a conservative analysis.

As noted in Table 1, refinements to the raw trip generation estimates have been made to provide a more detailed breakdown of trips between passenger cars and trucks. Trip generation for heavy trucks was further broken down by truck type (or axle type).

TABLE 1: PROJECT TRIP GENERATION RATES

The Project is estimated to generate a total of 88 two-way trips per day on a typical weekday as shown in Table 2.

TABLE 2: PROJECT TRIP GENERATION SUMMARY

The Project is forecasted to generate 88 daily vehicle trips, which is below the 110 daily trip threshold.

The Project Type Screening step is met.

EXECUTIVE SUMMARY

The approximately 1.6-acre project site is located at the southwest corner of the intersection of West Minthorn Street and North Riley Street in the City of Lake Elsinore, California. The project site is currently vacant and zoned as Limited Manufacturing District (M-1).

The proposed project includes the development of a concrete pumping truck storage yard, minor maintenance, and administrative office building of approximately 7,500 square feet. Access to the site would be accommodated via the two proposed driveways on North Riley Street.

The Project will have 10-12 concrete pump semi-trucks parked on the site. Each day most will leave the yard and return. Trucks that are not working receive needed light duty maintenance such as tires, pipes, hoses, check and maintain fluids, fix mirror or windshield, etc. to be ready for use the following day. No major repair work is done on-site. Trucks will leave the yard, go directly to different jobsites each day, meet with concrete mixing trucks at the site and concrete is poured from the concrete trucks through the pumps to place concrete at the jobsite. Trucks will be washed out and cleaned off-site before returning to the yard. Trucks will also be re-fueled off-site. Sales and parts ordering personnel will work out of the administrative office. Typical operations will occur Monday through Friday (with occasional weekend operations) from 4:00 AM to 6:00 PM. There will be approximately 10-12 employees on the site at any given time.

Existing Noise Environment

Sensitive receptors that may be affected by project generated noise include the property lines of the existing single-family residential uses located approximately 480 feet to the east (at the northeast corner of Minthorn Street and Spring Street), 425 feet to the southwest (along Langstaff Street), 460 feet east (along Spring Street), and 595 feet southeast (along Flint Street) and the single-family and multi-family residential uses located approximately 300 feet to the west (along Langstaff Street) of the project site boundaries.

Measured short-term ambient noise levels in the project vicinity ranged between 53 and 67.7 dBA L eq and long-term ambient noise levels ranged between 49.7 to 61.3 dBA L eq. The dominant noise source in the project vicinity was vehicle traffic Interstate 15, W Flint Street, N Spring Street, N Langstaff and other surrounding roadways.

Construction Noise Impacts

The project will comply with the hours specified in Section 17.176.080 of the City of Lake Elsinore Municipal Code. Based on the modeled construction noise levels, project construction noise levels will not exceed the applicable City mobile equipment noise thresholds at any of the modeled receptors. No mitigation is required.

On-Site Operation Noise Impacts

project operational noise is expected to range between 35.8 and 43.9 dBA L eq at nearby land uses and will not exceed the applicable stationary noise standards. This impact would be less than significant. No mitigation is required.

Mobile Source Noise Impacts

The addition of project trips is not expected to change noise levels more than the applicable threshold at any of the study roadway segments. The project impact is less than significant; no mitigation is required.

Groundborne Vibration Impacts

Fleming Concrete Pumping Truck Yard
Noise Impact Analysis
iv 19687
Groundborne vibration generated by project construction would not exceed the levels necessary to cause architectural damage to sensitive receptors. In addition, due to the distance to the nearest sensitive receptors, the threshold for annoyance due to vibration would not be anticipated to be exceeded. Furthermore, perceptibility of construction vibration would be temporary and would occur only during daytime hours. This impact would be less than significant. No mitigation is required.

Air Traffic Impacts

The closest airport to the project site is Skylark Airport, with airport runways located as close as approximately

3.06 miles to the southeast of the project site. Therefore, as Skylark Airport is further than two miles from the project site and is a small private airport, the proposed project would not expose people residing in or working in the area to excessive noise levels. The impact would be less than significant; no mitigation is required.

1. INTRODUCTION

This section describes the purpose of this study and the proposed project.

PURPOSE AND OBJECTIVES

The purpose of this report is to provide an assessment of the noise impacts resulting from development of the proposed project and to identify mitigation measures that may be necessary to reduce those impacts. The noise issues related to the proposed land use and development have been evaluated in light of applicable federal, state and local policies, including those of the City of Lake Elsinore, in the context of the California Environmental Quality Act (CEQA).

Although this is a technical report, effort has been made to write the report clearly and concisely. A list of acronyms and glossary are provided in Appendix A and Appendix B of this report to assist the reader with technical terms related to noise and vibration analysis.

PROJECT LOCATION

The approximately1.6-acre project site is located at the southwest corner of the intersection of West Minthorn Street and North Riley Street in the City of Lake Elsinore, California. The project site is currently vacant and zoned as Limited Manufacturing District (M-1). A vicinity map showing the project location is provided on Figure 1.

2. NOISE AND VIBRATION FUNDAMENTALS

This section provides an overview of key noise and vibration concepts.

NOISE FUNDAMENTALS

Sound is a pressure wave created by a moving or vibrating source that travels through an elastic medium such as air. Noise is defined as unwanted or objectionable sound. The effects of noise on people can include general annoyance, interference with speech communication, sleep disturbance, and in extreme circumstances, hearing impairment.

Commonly used noise terms are presented in Appendix B. The unit of measurement used to describe a noise level is the decibel (dB). The human ear is not equally sensitive to all frequencies within the sound spectrum.

Therefore, the “A-weighted” noise scale, which weights the frequencies to which humans are sensitive, is used for measurements. Noise levels using A-weighted measurements are written dB(A) or dBA.

From the noise source to the receiver, noise changes both in level and frequency spectrum. The most obvious is the decrease in noise as the distance from the source increases. The manner in which noise reduces with distance depends on whether the source is a point or line source as well as ground absorption, atmospheric effects and refraction, and shielding by natural and manmade features. Sound from point sources, such as air conditioning condensers, radiates uniformly outward as it travels away from the source in a spherical pattern.

The noise drop-off rate associated with this geometric spreading is 6 dBA per each doubling of the distance (dBA/DD). Transportation noise sources such as roadways are typically analyzed as line sources, since at any given moment the receiver may be impacted by noise from multiple vehicles at various locations along the roadway. Because of the geometry of a line source, the noise drop-off rate associated with the geometric spreading of a line source is 3 dBA/DD.

Decibels are measured on a logarithmic scale, which quantifies sound intensity in a manner similar to the Richter scale used for earthquake magnitudes. Thus, a doubling of the energy of a noise source, such as a doubled traffic volume, would increase the noise levels by 3 dBA; halving of the energy would result in a 3 dBA decrease. Figure 3 shows the relationship of various noise levels to commonly experienced noise events.

Average noise levels over a period of minutes or hours are usually expressed as dBA L eq, or the equivalent noise level for that period of time. For example, Leq(3-hr) would represent a 3-hour average. When no period is specified, a one-hour average is assumed.

Noise standards for land use compatibility are stated in terms of the Community Noise Equivalent Level (CNEL) and the Day-Night Average Noise Level (DNL). CNEL is a 24-hour weighted average measure of community noise. CNEL is obtained by adding five decibels to sound levels in the evening (7:00 PM to 10:00 PM), and by adding ten decibels to sound levels at night (10:00 PM to 7:00 AM). This weighting accounts for the increased human sensitivity to noise during the evening and nighttime hours. DNL is a very similar 24- hour average measure that weights only the nighttime hours.

It is widely accepted that the average healthy ear can barely perceive changes of 3 dBA; that a change of 5 dBA is readily perceptible, and that an increase (decrease) of 10 dBA sounds twice (half) as loud. This definition is recommended by the California Department of Transportation’s Technical Noise Supplement to the Traffic Noise Analysis Protocol (2013).

VIBRATION FUNDAMENTALS

The way in which vibration is transmitted through the earth is called propagation. Propagation of earthborn vibrations is complicated and difficult to predict because of the endless variations in the soil through which waves travel. There are three main types of vibration propagation: surface, compression and shear waves. 4 Fleming Concrete Pumping Truck Yard
Noise Impact Analysis
5 19687
Surface waves, or Rayleigh waves, travel along the ground’s surface. These waves carry most of their energy along an expanding circular wave front, similar to ripples produced by throwing a rock into a pool of water.

Compression waves, or P-waves, are body waves that carry their energy along an expanding spherical wave front. The particle motion in these waves is longitudinal (i.e., in a “push-pull” fashion). P-waves are analogous to airborne sound waves. Shear waves, or S-waves, are also body waves that carry energy along an expanding spherical wave front. However, unlike P-waves, the particle motion is transverse or “side-to-side and perpendicular to the direction of propagation”.

As vibration waves propagate from a source, the energy is spread over an ever-increasing area such that the energy level striking a given point is reduced with the distance from the energy source. This geometric spreading loss is inversely proportional to the square of the distance. Wave energy is also reduced with distance as a result of material damping in the form of internal friction, soil layering, and void spaces. The amount of attenuation provided by material damping varies with soil type and condition as well as the frequency of the wave.

Vibration amplitudes are usually expressed as either peak particle velocity (PPV) or the root mean square (RMS) velocity. The PPV is defined as the maximum instantaneous peak of the vibration signal in inches per second. The RMS of a signal is the average of the squared amplitude of the signal in vibration decibels (VdB), ref one micro-inch per second. The Federal Railroad Administration uses the abbreviation “VdB” for vibration decibels to reduce the potential for confusion with sound decibel.

PPV is appropriate for evaluating the potential of building damage and VdB is commonly used to evaluate human response. Decibel notation acts to compress the range of numbers required in measuring vibration.

Similar to the noise descriptors, L eq and Lmax can be used to describe the average vibration and the maximum vibration level observed during a single vibration measurement interval. Figure 4 illustrates common vibration sources and the human and structural responses to ground-borne vibration. As shown in the figure, the threshold of perception for human response is approximately 65 VdB; however, human response to vibration is not usually substantial unless the vibration exceeds 70 VdB. Vibration tolerance limits for sensitive instruments such as magnetic resonance imaging (MRI) or electron microscopes could be much lower than the human vibration perception threshold.

3. EXISTING NOISE ENVIRONMENT

This section describes the existing noise setting in the project vicinity.

EXISTING LAND USES AND SENSITIVE RECEPTORS

The project site is generally bordered by W Minthorn Street to the north; N Riley Street to the east; W Flint Street to the south; and the Temescal Wash/Lake Elsinore Outflow Channel to the west.

The State of California defines sensitive receptors as those land uses that require serenity or are otherwise adversely affected by noise events or conditions. Schools, libraries, churches, hospitals, single and multiple- family residential, including transient lodging, motels and hotel uses make up the majority of these areas.

Sensitive land uses that may be affected by project noise include the property lines of the existing single- family residential uses located approximately 480 feet to the east (at the northeast corner of Minthorn Street and Spring Street), 425 feet to the southwest (along Langstaff Street), 460 feet east (along Spring Street), and 595 feet southeast (along Flint Street) and the single-family and multi-family residential uses located approximately 300 feet to the west (along Langstaff Street) of the project site boundaries.

AMBIENT NOISE MEASUREMENTS

An American National Standards Institute (ANSI Section S1.4 2014 Class 1) Larson Davis model LxT sound level meter was used to document existing ambient noise levels. In order to document existing ambient noise levels in the project area, three (3) 15-minute daytime noise measurements were taken between 12:23 PM and 2:05 PM on November 28, 2023. In addition, one (1) long-term 24-hour noise measurement was also taken from November 28, 2023, to November 29, 2023. Figure 5 shows the noise measurement location map. Field worksheets and noise measurement worksheets are provided in Appendix C.

As shown in Figure 5, the noise meter was placed at the following locations:

 STNM1: represents the existing noise environment of the single-family residential uses located southwest of the project site along Langstaff Street (416 N Langstaff Street, Lake Elsinore). The noise meter was placed just northeast of the residential use.

 STNM2: represents the existing noise environment of the single-family residential uses along W Flint Street (109 W Flint Street, Lake Elsinore). The noise meter was placed just south of the southern property line of the residential use and just north of W Flint Street.

 STNM3: represents the existing noise environment of the single-family residential uses located to the east of the project site along N Spring Street (516 N Spring Street, Lake Elsinore). The noise meter was placed just west of the western property line of the residential use and just east of N Spring Street.

 LTNM1: represents the existing noise environment of the residential uses located west of the project site along N Langstaff Street (513 N Langstaff Street, Lake Elsinore). The noise meter was placed just east of the eastern property line of the residential use and just west of N Langstaff Street.

Table 1 provides a summary of the short-term ambient noise data. Table 2 provides hourly interval ambient noise data from the long-term noise measurements. Measured short-term ambient noise levels ranged between 53 and 67.7 dBA L eq. Long-term hourly noise measurement ambient noise levels ranged from 49.7 to 61.3 dBA Leq. The dominant noise source was vehicle traffic associated with the 15 Freeway, W Flint Street, N Spring Street, N Langstaff and other surrounding roadways. 8 Site Location Time Started Leq Lmax Lmin L(2) L(8) L(25) L(50) STNM1 12:23 PM 53.0 57.6 49.0 55.9 54.8 53.6 52.7

4. REGULATORY SETTING

This section documents the regulatory framework and applicable noise standards.

FEDERAL REGULATION

Federal Noise Control Act of 1972

The U.S. Environmental Protection Agency (EPA) Office of Noise Abatement and Control was originally established to coordinate federal noise control activities. After its inception, EPA’s Office of Noise Abatement and Control issued the Federal Noise Control Act of 1972, establishing programs and guidelines to identify and address the effects of noise on public health, welfare, and the environment. In response, the EPA published Information on Levels of Environmental Noise Requisite to Protect Public Health and Welfare with an Adequate Margin of Safety (Levels of Environmental Noise). The Levels of Environmental Noise recommended that the Ldn should not exceed 55 dBA outdoors or 45 dBA indoors to prevent significant activity interference and annoyance in noise-sensitive areas.

In 1981, EPA administrators determined that subjective issues such as noise would be better addressed at lower levels of government. Consequently, in 1982 responsibilities for regulating noise control policies were transferred to State and local governments. However, noise control guidelines and regulations contained in EPA rulings in prior years remain in place by designated Federal agencies, allowing more individualized control for specific issues by designated Federal, State, and local government agencies.

STATE REGULATIONS

State of California General Plan Guidelines 2017

Though not adopted by law, the State of California General Plan Guidelines 2017, published by the California Governor’s Office of Planning and Research (OPR) (OPR Guidelines), provides guidance for the compatibility of projects within areas of specific noise exposure. The OPR Guidelines identify the suitability of various types of construction relative to a range of outdoor noise levels and provide each local community some flexibility in setting local noise standards that allow for the variability in community preferences. Findings presented in the Levels of Environmental Noise Document (EPA 1974) influenced the recommendations of the OPR Guidelines, most importantly in the choice of noise exposure metrics (i.e., Ldn or CNEL) and in the upper limits for the normally acceptable outdoor exposure of noise-sensitive uses.

The OPR Guidelines include a Noise and Land Use Compatibility Matrix which identifies acceptable and unacceptable community noise exposure limits for various land use categories. Where the “normally acceptable” range is used, it is defined as the highest noise level that should be considered for the construction of the buildings which do not incorporate any special acoustical treatment or noise mitigation. The “conditionally acceptable” or “normally unacceptable” ranges include conditions calling for detailed acoustical study prior to the construction or operation of the proposed project.

California Department of Transportation (Caltrans)

The California Department of Transportation has published one of the seminal works for the analysis of ground-borne noise and vibration relating to transportation- and construction-induced vibrations and although the project is not subject to these regulations, it serves as useful tools to evaluate vibration impacts.

As shown in Table 3, the threshold at which there is a risk to “architectural” damage to historic and some older buildings is a peak particle velocity (PPV) of 0.25, at older residential structures a PPV of 0.3, and at new residential structures a PPV of 0.5. Table 4 shows that a PPV of 0.04 is the threshold at which groundborne vibration becomes distinctly perceptible in regard to annoyance. Therefore, these guidelines recommend that 12 Fleming Concrete Pumping Truck Yard
Noise Impact Analysis
13 19687
a standard of 0.3 inches per second (in/sec) PPV not be exceeded for the protection of older residential structures (California Department of Transportation, 2020).

LOCAL REGULATIONS

City of Lake Elsinore General Plan

The City of Lake Elsinore General Plan has established the following goals and policies in regard to noise which apply to the proposed project.

Goal 7 Maintain an environment for all City residents and visitors free of unhealthy, obtrusive, or otherwise excessive noise.

Policies

7.1 Apply the noise standards set forth in the Lake Elsinore Noise and Land Use Compatibility Matrix (see Table 5) and Interior and Exterior Noise Standards (see Table 6) when considering all new development and redevelopment proposed within the City.

7.2 Require that mixed-use structures and areas be designed to prevent transfer of noise and vibration from commercial areas to residential areas.

7.3 Strive to reduce the effect of transportation noise on the I-15.

7.4 Consider estimated roadway noise contours based upon Figure 3.6, Noise Contours of the General Plan, when making land use design decisions along busy roadways throughout the City.

7.5 Participate and cooperate with other agencies and jurisdictions in the development of noise abatement plans for highways.

City of Lake Elsinore Municipal Code

Section 17.176.060 Exterior noise limits.

A. Maximum permissible sound Levels by receiving land use.

1. The noise standards for the various categories of land use identified by the Noise Control Office(r) as presented in Table 7 shall, unless otherwise specifically indicated, apply to all such property within a designated zone.

2. No person shall operate, or cause to be operated, any source of sound at any location within the incorporated City or allow the creation of any noise on property owned, leased, occupied or otherwise controlled by such person, which causes the noise level when measured on any other property, either incorporated or unincorporated, to exceed:
a. The noise standard for that land use as specified in Table 7 for a cumulative period of more than 30 minutes in any hour; or
b. The noise standard plus five dB for a cumulative period of more than 15 minutes in any hour; or
c. The noise standard plus 10 dB for a cumulative period of more than five minutes in any hour; or
d. The noise standard plus 15 dB for a cumulative period of more than one minute in any hour; or
e. The noise standard plus 20 dB or the maximum measured ambient level, for any period of time.

3. If the measured ambient level differs from that permissible within any of the fast four noise limit categories above, the allowable noise exposure standard shall be adjusted in five dB increments in each category as appropriate to encompass or reflect said ambient noise level. 13 Fleming Concrete Pumping Truck Yard
Noise Impact Analysis
14 19687

4. If the measurement location is on a boundary between two different zones, the noise level limit applicable to the lower noise zone plus six dB shall apply.

5. If possible, the ambient noise shall be measured at the same location along the property line utilized in subsection (A)(2) of this section with the alleged offending noise source inoperative. If, for any reason, the alleged offending noise source cannot be shut down, the ambient noise must be estimated by performing a measurement in the same general area of the source but at a sufficient distance such that the noise from the source is at least 10 dB below the ambient in order that only the ambient level be measured. If the difference between the ambient and the noise source is five to 10 dB, then the level of the ambient itself can be reasonably determined by subtracting a one- decibel correction to account for the contribution of the source.

B. Correction for Character of Sound. In the event the alleged offensive noise, as judged by the Noise Control Officer, contains a steady, audible tone such as a whine, screech, or hum, or is a repetitive noise such as hammering or riveting, or contains music or speech conveying informational content, the standard limits set forth in Table 7 shall be reduced by five dB.

Section 17.176.070 Interior noise standards.

A. Maximum permissible dwelling interior sound levels.

1. The interior noise standards for multifamily residential dwellings as presented in Table 8 shall apply, unless otherwise specifically indicated, within all such dwellings with windows in their normal seasonal configuration.

2. No person shall operate or cause to be operated within a dwelling unit, any source of sound or allow the creation of any noise which causes the noise level when measured inside a neighboring receiving dwelling unit to exceed:
a. The noise standard as specified in Table 8 for a cumulative period of more than five minutes in any hour; or
b. The noise standard plus five dB for a cumulative period of more than one minute in any hour; or
c. The noise standard plus 10 dB or the maximum measured ambient, for any period of time.

3. If the measured ambient level differs from that permissible within any of the noise limit categories above, the allowable noise exposure standard shall be adjusted in five dB increments in each category as appropriate to reflect said ambient noise level.

Section 17.176.080 Prohibited acts.

No person shall unnecessarily make, continue, or cause to be made or continued, any noise disturbance. The following acts, and the causing or permitting thereof, are declared to be in violation of this chapter:

E. Loading, unloading, opening, closing or other handling of boxes, crates, containers, building materials, garbage cans, or similar objects between the hours of 10:00 PM and 7:00 AM in such a manner as to cause a noise disturbance across a residential real property line or at any time to violate the provisions of LEMC 17.176.060(A).

F. Construction/Demolition.

1. Operating or causing the operation of any tools or equipment used in construction, drilling, repair, alteration, or demolition work between weekday hours of 7:00 PM and 7:00 AM, or at any time on weekends or holidays, such that the sound therefrom creates a noise disturbance across a residential or commercial real property line, except for emergency work of public service utilities or by variance issued by the City.
14 Fleming Concrete Pumping Truck Yard

15 19687

2. Noise Restrictions at Affected Properties. Where technically and economically feasible, construction activities shall be conducted in such a manner that the maximum noise levels at affected properties will not exceed those listed in the schedule provided in Table 9.

3. All mobile or stationary internal combustion engine powered equipment or machinery shall be equipped with suitable exhaust and air intake silencers in proper working order.

G. Operating or permitting the operation of any device that creates a vibration which is above the vibration perception threshold of any individual at or beyond the property boundary of the source if on private property or at 150 feet (46 meters) from the source if on a public space or public right-of-way.

K. Noise Sensitive Zones.

1. Creating or causing the creation of any sound within any noise sensitive zone, so as to exceed the specified land use noise standards set forth in LEMC 17.176.060(A); provided, that conspicuous signs are displayed indicating the zone; or

2. Creating or causing the creation of any sound within or adjacent to any noise sensitive zone, containing a hospital, nursing home, school, court or other designated area, so as to interfere with the functions of such activity or annoy the occupants in the activity; provided, that conspicuous signs are displayed indicating the presence of the zone.

5. ANALYTICAL METHODOLOGY AND MODEL PARAMETERS

This section discusses the analysis methodologies used to assess noise impacts.

CONSTRUCTION NOISE MODELING

Construction noise will vary depending on the construction process, type of equipment involved, location of the construction site with respect to sensitive receptors, the schedule proposed to carry out each task (e.g., hours and days of the week) and the duration of the construction work.

Construction noise associated with the proposed project was calculated at the sensitive receptor locations utilizing methodology presented in the Federal Transit Administration (FTA) Transit Noise and Vibration Impact Assessment Manual (2018) together with several key construction parameters, including: distance to each sensitive receiver, equipment usage, percent usage factor, and baseline parameters for the project site.

Distances to receptors were based on the acoustical center of the project site.

The equipment used to calculate the construction noise levels for each phase were based on the assumptions provided in the CalEEMod modeling in the Air Quality and Greenhouse Gas Assessment prepared for the proposed project (Urban Crossroads, 2023). For analysis purposes, the distance measured from the project site to sensitive receptors was assumed to be the acoustical center of the project site to the property line of residential properties with existing residential buildings. Sound emission levels associated with typical construction equipment as well as typical usage factors are provided in Table 10 . Construction noise worksheets are provided in Appendix D.

STATIONARY SOURCE/OPERATIONAL NOISE MODELING

The SoundPLAN acoustical modeling software was utilized to model project operational stationary noise levels from the proposed project to adjacent sensitive uses (e.g., residences). SoundPLAN is capable of evaluating stationary noise sources (e.g., parking lots, drive-through menus, car wash equipment, vacuums, etc.). The SoundPLAN software utilizes algorithms (based on the inverse square law) to calculate noise level projections.

The software allows the user to input specific noise sources, spectral content, sound barriers, building placement, topography, and sensitive receptor locations. In addition to the information provided below, noise modeling input and outputs assumptions are provided in Appendix E.

Operational noise levels were modeled utilizing representative sound levels in the SoundPLAN model.

Modeled noise sources include parking lot noise and HVAC equipment. All noise sources were modeled to be in full operation for an entire hour.

Parking Lot Noise

Parking lot noise was calculated using SoundPLAN methodology. Specifically, the traffic volume of the parking lot is entered with the number of moves per parking space, the hour and the number of parking bays. The user defines whether the parking lots are for automobiles, motorcycles, or trucks, and the emission level of a parking lot is automatically adjusted accordingly. The values for the number of parking moves for each time slice is the number of parking moves per reference unit (most often per parking bay), averaged for the hour 1.

SoundPLAN utilizes parking lot noise emission levels from the 6th revised edition of the parking lot study “Recommendations for the Calculation of Sound Emissions of Parking Areas, Motorcar Centers and Bus Stations as well as of Multi-Story Car Parks and Underground Car Parks” published by the Bavarian Landesamt für Umwelt provides calculation methods to determine the emissions of parking lots.

The parking lot emission table documents the reference level (Lw, ref) from parking lot study:

Lw, ref = Lw0 + KPA + KI + KD + KStrO + 10 log(B) [dB(A)]

With the following parameters:

Lw0 = Basic sound power, sound power level of one motion / per hour on P+R areas = 63 dB(A) KPA = Surcharge parking lot type
KI = Surcharge for impulse character
KD = Surcharge for the traffic passaging and searching for parking bays in the driving lanes 2.5 * lg (f * B - 9)
f = Parking bays per unit of the reference value
B = Reference value
KStrO = Surcharge for the road surface
B = Reference value

Mechanical Equipment (HVAC Units) Noise

A noise reference level of 67.7 dBA at 3 feet (sound power level of 78.7 dB) was utilized to represent rooftop 50 Ton Carrier HVAC units2. The noise source height for each HVAC unit was assumed at 1 meter above the roof top. Roof top is assumed to be approximately 40 feet (~12.2 meters) above grade. It is assumed that no HVAC equipment will be stored at ground level outside of the proposed building. A total of eight rooftop units were modeled.

MOBILE SOURCE NOISE MODELING

Noise from vehicular traffic was projected using a computer program that replicates the FHWA Traffic Noise Prediction Model (FHWA-RD-77-108). The FHWA model arrives at the predicted noise level through a series of adjustments to the Reference Energy Mean Emission Level (REMEL). Key model parameters and REMEL adjustments are presented below:

 Roadway classification (e.g., freeway, major arterial, arterial, secondary, collector, etc.)  Roadway active width (distance between the center of the outer most travel lanes on each side of the roadway)
 Average Daily Traffic (ADT) Volumes, Travel Speeds, Percentages of automobiles, medium trucks and heavy trucks
 Roadway grade and angle of view
 Site conditions (e.g., soft vs. hard)
 Percentage of total ADT which flows each hour throughout a 24-hour period.

Table 11 shows the roadway volumes, speeds, and site conditions used in the analysis. The following outlines key adjustments made to the REMEL for project site parameter inputs:

 Vertical and horizontal distances (sensitive receptor distance from noise source)  Noise barrier vertical and horizontal distances (noise barrier distance from sound source and receptor).  Traffic noise source spectra
 Topography

Traffic noise levels were calculated at the right-of-way based on distance from the centerline of the analyzed roadway. The modeling is theoretical and does not take into account any existing barriers, structures, and/or topographical features that may further reduce noise levels. Therefore, the modeled noise levels are shown

for comparative purposes only to show the difference between with and without project conditions. The traffic noise calculation worksheets are included in Appendix F.

GROUNDBORNE VIBRATION MODELING

Groundborne vibration modeling was performed using vibration propagation equations and construction equipment source levels obtained from the FTA Transit Noise and Vibration Impact Assessment Manual (2018).

Table 12 shows typical vibration levels associated with commonly used construction equipment based on data from the FTA.

There are several types of construction equipment that can cause vibration levels high enough to annoy people in the vicinity and/or result in architectural or structural damage to nearby structures and improvements. For example, as shown in Table 12, a vibratory roller could generate up to 0.21 in/sec PPV at and operation of a large bulldozer could generate up to 0.089 PPV at a distance of 25 feet (two of the most vibratory pieces of construction equipment). Groundborne vibration at sensitive receptors associated with this equipment would drop off as the equipment moves away. For example, as the vibratory roller moves further than 100 feet from the sensitive receptors, the vibration associated with it would drop below 0.0026 in/sec PPV. It should be noted that these vibration levels are reference levels and may vary slightly depending upon soil type and specific usage of each piece of equipment.

The fundamental equation used to calculate vibration propagation through average soil conditions and distance is as follows:

PPVequipment = PPVref (25/Drec)n

Where: PPVref = reference PPV at 25ft.

Drec = distance from equipment to receiver in ft.
n = 1.5 (the value related to the attenuation rate through ground)

Groundborne vibration calculations are provided in Appendix G.

6. NOISE AND VIBRATION IMPACTS

This section analyzes the significance of project-related noise and groundborne vibration impacts relative to standards established by the City of Lake Elsinore and other applicable agencies in the context of CEQA.

Appendix G of the California Environmental Quality Act Guidelines (Title 14, Division 6, Chapter 3 of the California Code of Regulations) includes an environmental checklist that identifies issues upon which findings of significance should be made. The CEQA Environmental Checklist Appendix G, XIII. Noise, requires determination if the project would result in:

a) Generation of 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?
b) Generation of excessive groundborne vibration or groundborne noise levels? c) For a project located within the vicinity of a private airstrip or an airport land use plan or, where such a plan has not been adopted, within two miles of a public airport or public use airport, would the project expose people residing or working in the area to excessive noise levels?

NOISE IMPACTS

Would the project result in:

Finding: Less Than Significant

In relation to the Environmental Checklist noise issue “a”, applicable standards established by the City of Lake Elsinore can be categorized into the following areas:

 Construction Noise
 Stationary Source Noise
 Mobile Source Noise

Construction Noise

Construction noise is regulated within Section 17.176.080 of the City of Lake Elsinore Municipal Code (see Regulatory Setting section of this report). Accordingly, the project would result in a significant impact if:

 Project construction occurs outside the weekday hours of 7:00 AM and 7:00 PM or at any time on weekends or holidays; or if project construction noise exceeds the following (see Table 9):

o At a place of business: 85 dBA from mobile equipment and 75 dBA from stationary equipment, o At a single-family residence: 75 dBA for mobile equipment and 60 dBA for stationary equipment, o At a multi-family residential building: 80 dBA for mobile equipment and 65 dBA for stationary equipment.

Project construction noise levels at nearby sensitive receptors were calculated using the FTA methodology.

Modeled locations are shown on Figure 6. Construction noise modeling worksheets for each phase are provided in Appendix D. Anticipated noise levels during each construction phase are presented in Table 13. 29 Fleming Concrete Pumping Truck Yard
Noise Impact Analysis
30 19687
As shown in Table 13, modeled construction noise levels reach up to 66.3 dBA L eq at the nearest residential property line to the northeast (131 Minthorn Street), up to 67.4 dBA L eq at the nearest commercial property line to the northwest, 68.8 dBA L eq at the nearest commercial property line to the northeast, 81 dBA L eq at the nearest industrial property line to the east, 65.4 dBA L eq at the nearest residential property line to the east, 62.2 dBA L eq at the nearest residential property line to the southeast, 62.6 dBA L eq at the nearest residential property line to the southwest, 72.9 dBA L eq at the nearest commercial property line to the west,

69.1 dBA Leq at the nearest single-family residential property line to the west, and 66.9 dBA Leq at the nearest multi-family residential property line to the west of the project site.

The project will comply with the allowed hours for construction specified in Section 17.176.080 of the City of Lake Elsinore Municipal Code; and based on the modeled construction noise levels (see Table 13), project construction noise levels will not exceed the applicable City mobile equipment noise thresholds at any of the modeled receptors.

Project Operational Noise (Onsite)

Interior and exterior noise standards for limiting noise pollution from one property to another are provided in the City of Lake Elsinore Municipal Code (see Table 7 and Table 8). Although not typically considered as “noise sensitive” land uses, noise standards are provided for commercial, industrial, and public land uses in addition to residential land uses. It should be noted that neither the General Plan nor the Municipal Code make clear as to whether the standards apply to existing land uses, the zone, or to the General Plan land use designation.

Existing sensitive receptors (existing residential land uses) in the project area are shown in Figure 6. The zoning of the project area is shown in Figure 7. For the purposes of this analysis, the more conservative assumption was utilized (existing land use). It should also be noted that per footnote 2 of Table 7, noise standards were adjusted based on existing measured noise levels.

Accordingly, the project would result in a significant impact if:

 Onsite operational would result in a significant impact if it exceeds any of the criteria provided below:

Land Use Exterior
Daytime Leq

Heavy Industrial 75 75

Onsite operational noise levels at nearby land uses were modeled using the SoundPLAN acoustical model.

SoundPLAN modeling worksheets are provided in Appendix E. A description of each noise source and model parameters are discussed in Section 5 of this report.

A conservative assumption was made that the total number of daily truck trips would occur during the modeled hour. As shown in Table 14, and on Figure 8 and Figure 9, project operational noise is expected to range between 35.8 and 43.9 dBA Leq at nearby land uses and will not exceed the applicable stationary noise standards. This impact would be less than significant. No mitigation is required.

Project Operational Noise (Offsite)

Noise Impact Analysis

California courts have rejected use of what is effectively a single “absolute noise level” threshold of significance (e.g., exceed 65 dBA CNEL) on the grounds that the use of such a threshold fails to consider the magnitude or severity of increases in noise levels attributable to the project in different environments (see King and Gardiner Farms, LLC v. County of Kern (2020) 45 Cal.App.5th 814). California courts have also upheld the use of “ambient plus increment” thresholds for assessing project noise impacts as consistent with CEQA, noting however, that the severity of existing noise levels should not be ignored by incorporating a smaller incremental threshold for areas where existing ambient noise levels were already high (see Mission Bay Alliance v. Office of Community Investment and Infrastructure (2016) 6 Cal.App.5th 160).

It is widely accepted that the average healthy human ear can barely perceive changes of 3 dBA in an outdoor environment and that a change of 5 dBA is readily perceptible.3 Therefore, considering relevant case law, the project would result in a significant impact if:

 The addition of project trips on surrounding roadways causes noise levels to increase by:
o 5 dBA where the existing ambient noise level is less than or equal to a CNEL of 60 dBA; or, o 3 dBA where the existing ambient noise level is a CNEL of 60 dBA to 65 dBA; or o 1.5 dBA where the existing ambient noise level is greater than or equal to a 65 dBA CNEL.

Mobile Source Noise

Roadway noise levels were calculated at roadways included in the Fleming & Sons Concrete, Pumping, Inc. Truck Yard Trip Generation Assessment (Ganddini Group, Inc., November 2, 2023) based on the FHWA Traffic Noise Prediction Model methodology. During operation, the proposed project is expected to generate approximately 88 average daily trips with 7 trips during the AM peak-hour and 17 trips during the PM peak-hour. Roadway noise levels were calculated for the following scenarios:
 Existing (without Project): This scenario refers to existing year traffic noise conditions.  Existing Plus Project: This scenario refers to existing year plus project traffic noise conditions.

Table 15 shows the change in existing roadway noise levels with the addition of project-generated operational trips. FHWA Traffic Noise Prediction Model calculation worksheets are provided in Appendix F.

As shown in Table 15, modeled existing traffic noise levels range between 71.14 and 72.18 dBA CNEL and the modeled Existing Plus Project traffic noise levels range between 71.24 and 72.24 dBA CNEL at the right- of-way of each study roadway segment.

In no case will project generated vehicle traffic result in an increase greater than 1.5 dB, and therefore, will not result in substantial increases in ambient noise levels along affected road segments (see Table 15). This impact is less than significant; no mitigation is required.

Construction Source Noise

Construction truck trips would occur throughout the construction period. Given the project site’s proximity to the 15 Freeway, it is anticipated that vendor and/or haul truck traffic would take the most direct route to the appropriate freeway ramps.

32 19687
Minthorn Street currently handles approximately 10,050 average daily vehicle trips. 4 According to the CalEEMod modeling in the Air Quality and Greenhouse Gas Assessment prepared for the proposed project (Urban Crossroads, 2023), the greatest number of construction-related vehicle trips per day would be during the grading phase of construction at up to approximately 88 vehicle trips per day (10 worker and 78.3 hauling trips per day). Therefore, vehicle traffic generated during project construction is nominal relative to existing roadway volumes and would not result in the doubling of traffic volume necessary to increase noise levels by 3 dBA. The project impact is less than significant; no mitigation is required.

GROUNDBORNE VIBRATION IMPACTS

Would the project result in:

b) Generation of excessive groundborne vibration or groundborne noise levels?

Finding: Less Than Significant

In relation to the Environmental Checklist noise issue “b”, the City of Lake Elsinore Municipal Code Section

17.176.080 states that operating or permitting the operation of any device that creates a vibration which is above the vibration perception threshold of any individual at or beyond the property boundary of the source if on private property or at 150 feet (46 meters) from the source if on a public space or public right-of-way is prohibited. However, the City does not specify a numerical threshold of significance concerning groundborne vibration. In the absence of a City-established numerical threshold, groundborne vibration impacts are based on guidance from the Transportation and Construction Vibration Guidance Manual (California Department of Transportation, 2020) (see Regulatory Setting section). Accordingly, the project would result in a significant impact if:

 Groundborne vibration levels generated by the project have the potential to cause architectural damage at nearby buildings by exceeding the following PPV:
□ 0.08 in/sec at extremely fragile historic buildings, ruins, ancient monuments □ 0.10 in/sec at fragile buildings
□ 0.25 in/sec at historic and some old buildings
□ 0.30 in/sec at older residential structures
□ 0.50 in/sec at new residential structures and modern industrial/commercial buildings.  Groundborne vibration levels generated by the project have the potential to cause annoyance to people living or working in nearby buildings by exceeding a PPV of 0.04 in/sec.

Groundborne vibration modeling worksheets are provided in Appendix G.

Based on the groundborne vibration modeling, use of a vibratory roller is expected to generate a PPV of 0.104 in/sec and use of a bulldozer is expected to generate a PPV of 0.044 in/sec at the closest off-site building, a commercial use located approximately 40 feet east of the project site ( Table 16). Therefore, groundborne vibration generated by project construction would not exceed the levels necessary to cause architectural damage.

As shown in Table 16, at all modeled sensitive uses, groundborne vibration would not exceed the annoyance threshold of a PPV of 0.04 in/sec. Therefore, groundborne vibration generated by project construction would not exceed the levels necessary to cause annoyance to persons living or working in nearby buildings. The project impact is less than significant; no mitigation is required.

4 As no existing average daily traffic volumes for Minthorn Street were available, to be conservative, this analysis utilized ambient noise measurements to estimate existing average daily vehicle trips. STNM3 (see Table 1) was used to estimate the existing average daily vehicle trips on Minthorn Street.
32 Fleming Concrete Pumping Truck Yard
Noise Impact Analysis
33 19687
The most substantial sources of groundborne vibration during post-construction project operations will include the movement of passenger vehicles and trucks on paved and generally smooth surfaces. Loaded trucks generally have a PPV of 0.076 at a distance of 25 feet (Caltrans 2020), which is a substantially lower PPV than that of a vibratory roller (0.210 in/sec PPV at 25 feet). Therefore, groundborne vibration levels generated by project operation would not exceed those modeled for project construction.

AIR TRAFFIC IMPACTS

Would the project result in:

c) For a project located within the vicinity of a private airstrip or an airport land use plan or, where such a plan has not been adopted, within two miles of a public airport or public use airport, would the project expose people residing or working in the area to excessive noise levels?

Finding: No Impact

The closest airport to the project site is Skylark Airport, with airport runways located as close as approximately

3.06 miles to the southeast of the project site. The City of Lake Elsinore General Plan sates that Skylark Airport is a privately owned airport which provides glider and skydiving opportunities with a gravel and sand runway surface, which does not permit optimal conditions for frequent and convenient airport operations. Therefore, as Skylark Airport is further than two miles from the project site and is a small private airport, the proposed project would not expose people residing in or working in the area to excessive noise levels. There is no impact, and no mitigation is required.

DEFINITIONS OF ACOUSTICAL TERMS
Apx-4

Term Definition
Ambient Noise
Level
The all-encompassing noise environment associated with a given environment, at a specified time, usually a composite of sound from many sources, at many directions, near and far, in which usually no particular sound is dominant.

A-Weighted Sound
Level, dBA
The sound level obtained by use of A-weighting. The A-weighting filter de-emphasizes the very low and very high frequency components of the sound in a manner similar to the frequency response of the human ear.

CNEL
Community Noise Equivalent Level. CNEL is a weighted 24-hour noise level that is obtained by adding five decibels to sound levels in the evening (7:00 PM to 10:00 PM), and by adding ten decibels to sound levels at night (10:00 PM to 7:00 AM). This weighting accounts for the increased human sensitivity to noise during the evening and nighttime hours.

Decibel, dB
A logarithmic unit of noise level measurement that relates the energy of a noise source to that of a constant reference level; the number of decibels is 10 times the logarithm (to the base 10) of this ratio.

DNL, Ldn
Day Night Level. The DNL, or Ldn is a weighted 24-hour noise level that is obtained by adding ten decibels to sound levels at night (10:00 PM to 7:00 AM). This weighting accounts for the increased human sensitivity to noise during the nighttime hours.

Equivalent
Continuous Noise
Level, Leq
A level of steady state sound that in a stated time period, and a stated location, has the same A-weighted sound energy as the time-varying sound.

Fast/Slow Meter
Response
The fast and slow meter responses are different settings on a sound level meter. The fast response setting takes a measurement every 100 milliseconds, while a slow setting takes one every second.

Frequency, Hertz In a function periodic in time, the number of times that the quantity repeats itself in one second (i.e., the number of cycles per second).

L02, L08, L50, L90 The A-weighted noise levels that are equaled or exceeded by a fluctuating sound level, 2 percent, 8 percent, 50 percent, and 90 percent of a stated time period, respectively.

Lmax, Lmin
Lmax is the RMS (root mean squared) maximum level of a noise source or environment measured on a sound level meter, during a designated time interval, using fast meter response. Lmin is the minimum level.

Offensive/
Offending/Intrusive
Noise
The noise that intrudes over and above the existing ambient noise at a given location.

The relative intrusiveness of sound depends on its amplitude, duration, frequency, and time of occurrence, and tonal information content as well as the prevailing ambient noise level.

Root Mean Square
(RMS)
A measure of the magnitude of a varying noise source quantity. The name derives from the calculation of the square root of the mean of the squares of the values. It can be calculated from either a series of lone values or a continuous varying function.

PROJECT AIR QUALITY IMPACTS

AIR QUALITY SETTING

SOUTH COAST AIR BASIN (SCAB)
The Project site is located in the SCAB within the jurisdiction of South Coast Air Quality Management District (SCAQMD) (1). The SCAQMD was created by the 1977 Lewis- Presley Air Quality Management Act, which merged four county air pollution control bodies into one regional district. Under the Act, the SCAQMD is responsible for bringing air quality in areas under its jurisdiction into conformity with federal and state air quality standards. As previously stated, the Project site is located within the SCAB, a 6,745 -square mile subregion of the SCAQMD, which includes portions of Los Angeles, Riverside, and San Bernardino Counties, and all of Orange County.

The SCAB is bounded by the Pacific Ocean to the west and the San Gabriel, San Bernardino, and San Jacinto Mountains to the north and east. The Los Angeles County portion of the Mojave Desert Air Basin is bounded by the San Gabriel Mountains to the south and west, the Los Angeles / Kern County border to the north, and the Los Angeles / San Bernardino County border to the east. The Riverside County portion of the Salton Sea Air Basin is bounded by the San Jacinto Mountains in the west and spans eastward up to the Palo Verde Valley.

Regional Climate
The regional climate has a substantial influence on air quality in the SCAB. In addition, the temperature, wind, humidity, precipitation, and amount of sunshine influence the air quality.

The annual average temperatures throughout the SCAB vary from the low to middle 60s degrees Fahrenheit (°F). Due to a decreased marine influence, the eastern portion of the SCAB shows greater variability in average annual minimum and maximum temperatures. January is the coldest month throughout the SCAB, with average minimum temperatures of 47°F in downtown Los Angeles and 36°F in San Bernardino. All portions of the SCAB have recorded maximum temperatures above 100°F.

Although the climate of the SCAB can be characterized as semi-arid, the air near the land surface is quite moist on most days because of the presence of a marine layer. This shallow layer of sea air is an important modifier of SCAB climate. Humidity restricts visibility in the SCAB, and the conversion of sulfur dioxide (SO
2) to sulfates (SO4) is heightened in air with high relative humidity.

The marine layer provides an environment for that conversion process, especially during the spring and summer months. The annual average relative humidity within the SCAB is 71 percent (%) along the coast and 59% inland. Since the ocean effect is dominant, periods of heavy early morning fog are frequent and low stratus clouds are a characteristic feature. These effects decrease with distance from the coast.

More than 90% of the SCAB’s rainfall occurs from November through April. The annual average rainfall varies from approximately nine inches in Riverside to fourteen inches in downtown Los Angeles. Monthly and yearly rainfall totals are extremely variable. Summer rainfall usually consists of widely scattered thunderstorms near the coast and slightly heavier shower activity in the eastern portion of the SCAB with frequency being higher near the coast.

15715-03 AQ & GHG Assessment
Due to its generally clear weather, about three -quarters of available sunshine is received in the SCAB. The remaining one-quarter is absorbed by clouds. The ultraviolet portion of this abundant radiation is a key factor in photochemical reactions. On th e shortest day of the year there are approximately 10 hours of possible sunshine, and on the longest day of the year there are approximately 14½ hours of possible sunshine.

The importance of wind to air pollution is considerable. The direction and speed of the wind determines the horizontal dispersion and transport of the air pollutants. During the late autumn to early spring rainy season, the SCAB is subjected to wind flow s associated with the traveling storms moving through the region from the northwest. This period also brings five to ten periods of strong, dry offshore winds, locally termed “Santa Anas” each year. During the dry season, which coincides with the months of maximum photochemical smog concentrations, the wind flow is bimodal, typified by a daytime onshore sea breeze and a nighttime offshore drainage wind.

Summer wind flows are created by the pressure differences between the relatively cold ocean and the unevenly heated and cooled land surfaces that modify the general northwesterly wind circulation over southern California. Nighttime drainage begins with the radiational cooling of the mountain slopes. Heavy, cool air descends the slopes and flows through the mountain passes and canyons as it follows the lowering terrain toward the ocean. Another characteristic wind regime in the SCAB is the “Catalina Eddy,” a low level cyclonic (counterclockwise) flow centered over Santa Catalina Island which results in an offshore flow to the southwest. On most spring and summer days, some indication of an eddy is apparent in coastal sections.

In the SCAB, there are two distinct temperature inversion structures that control vertical mixing of air pollution. During the summer, warm high-pressure descending (subsiding) air is undercut by a shallow layer of cool marine air. The boundary between these two layers of air is a persistent marine subsidence/inversion. This boundary prevents vertical mixing which effectively acts as an impervious lid to pollutants over the entire SCAB. The mixing height for the inversion structure is normally situated 1,000 to 1,500 feet above mean sea level.

A second inversion-type forms in conjunction with the drainage of cool air off the surrounding mountains at night followed by the seaward drift of this pool of cool air. The top of this layer forms a sharp boundary with the warmer air aloft and creates nocturnal radiation inversions.

These inversions occur primarily in the winter when nights are longer and onshore flow is weakest. They are typically only a few hundred feet above mean sea level. These inversions effectively trap pollutants, such as nitro gen oxides (NO X) and carbon monoxide (CO) from
vehicles, as the pool of cool air drifts seaward. Winter is therefore a period of high levels of primary pollutants along the coastline.

Wind Patterns and Project Location
The distinctive climate of the Project area and the SCAB is determined by its terrain and geographical location. The SCAB is located in a coastal plain with connecting broad valleys and low hills, bounded by the Pacific Ocean in the southwest quadrant with high mountains forming the remainder of the perimeter.

Wind patterns across the south coastal region are characterized by westerly and southwesterly onshore winds during the day and easterly or northeasterly breezes at night. Winds are characteristically light although the speed is somewhat greater during the dry summer months than during the rainy winter season.

Criteria Pollutants
Both the U.S. Environmental Protection Agency (EPA) and the California Air Resources Board (CARB) have established ambient air quality standards for common pollutants. These ambient air quality standards are levels of contaminants representing safe levels that avoid specific adverse health effects associated with each pollutant. The ambient air quality standards cover what are called “criteria” pollutants because the health and other effects of each pollutant are described in criteria documents. The six criteria pollutants are ozone (O 3) (precursor emissions include NOX
and reactive organic gases (ROG), CO, particulate matter (PM), nitrogen dioxide (NO 2), sulfur dioxide (SO2), and lead. Areas that meet ambient air quality standards are classified as attainment areas, while areas that do not meet these standards are classified as nonattainment areas. The Riverside County portion of the SCAB is designated as a nonattainment area for the federal O 3 and PM2.5 standards and is also a nonattainment area for the state standards for O 3, PM10, and PM2.5.

Toxic Air Contaminants (TAC) Trend
In 1984, as a result of public concern for exposure to airborne carcinogens, CARB adopted regulations to reduce the amount of TAC emissions resulting from mobile and area sources, such as cars, trucks, stationary products, and consumer products. According to the Ambient and Emission Trends of Toxic Air Contaminants in California journal article (2) which was prepared for CARB, results show that between 1990-2012, ambient concentration and emission trends for the seven TACs responsible for most of the known cancer risk associated with airborne exposure in California have declined significantly (betwe en 1990 and 2012). The seven TACs studied include those that are derived from mobile sources: diesel particulate matter (DPM), benzene (C 6H6), and
1,3-butadiene (C4H6); those that are derived from stationary sources: perchloroethylene (C 2Cl4) and hexavalent chromium (Cr(VI)); and those derived from photochemical reactions of emitted VOCs: formaldehyde (CH
2O) and acetaldehyde (C 2H4O)1. The decline in ambient concentration and emission trends of these TACs are a result of various regulations CARB has implemented to address cancer risk.

Sensitive Receptor Locations
Some people are especially sensitive to air pollution and are given special consideration when evaluating air quality impacts from projects. These groups of people include children, the elderly, and individuals with pre-existing respiratory or cardiovascular illness. Structures that house these persons or places where they gather are defined as “sensitive receptors”. These structures typically include uses such as residences, hotels, and hospitals where an individual can remain for 24 hours. Consistent with the LST Methodology, the nearest land use where an individual could remain for 24 hours to the Project site has been used to determine construction and operational air quality impacts for emissions of PM
10 and PM2.5, since PM10 and PM2.5 thresholds
are based on a 24-hour averaging time.

Receptors in the Project study area are described below. All distances are measured from the Project site boundary to the outdoor living areas (e.g., backyards) or at the building façade,

1 It should be noted that ambient DPM concentrations are not measured directly. Rather, a surrogate method using the coefficient of haze (COH) and elemental carbon (EC) is used to estimate DPM concentrations.

REGULATORY BACKGROUND

FEDERAL REGULATIONS
The EPA is responsible for setting and enforcing the national ambient air quality standards (NAAQS) for O 3, CO, NO X, SO2, PM10, and lead (Pb) (3). The EPA has jurisdiction over emissions sources that are under the authority of the federal government including aircraft, locomotives, and emissions sources outside state waters (Outer Continental Shelf). The EPA also establishes emission standards for vehicles sold in states other than California. Automobiles sold in California must meet the stricter emission requirements of CARB.

The Federal Clean Air Act (CAA) was first enacted in 1955 and has been amended numerous times in subsequent years (1963, 1965, 1967, 1970, 1977, and 1990). The CAA establishes the federal air quality standards, the NAAQS, and specifies future dates for achieving compliance (4). The CAA also mandates that each state submit and implement state implementation plans (SIPs) for local areas not meeting these standards. These plans must include pollution control measures that demonstrate how the standards will be met.

The 1990 amendments to the CAA that identify specific emission reduction goals for areas not meeting the NAAQS require a demonstration of reasonable further progress toward attainment and incorporate additional sanctions for failure to attain or to meet in terim milestones. The sections of the CAA most directly applicable to the development of the Project site include Title I (Non-Attainment Provisions) and Title II (Mobile Source Provisions) (5) (6). Title I provisions were established with the goal of attaining the NAAQS for the following criteria pollutants O 3, NO2, SO2,
PM10, CO, PM2.5, and Pb. The NAAQS were amended in July 1997 to include an additional standard for O3 and to adopt a NAAQS for PM2.5.

Mobile source emissions are regulated in accordance with Title II provisions. These provisions require the use of cleaner burning gasoline and other cleaner burning fuels such as methanol and natural gas. Automobile manufacturers are also required to reduce tailpipe emissions of hydrocarbons and NO
X. NOX is a collective term that includes all forms of NOX which are emitted as byproducts of the combustion process.

CALIFORNIA REGULATIONS
CARB
The CARB, which became part of the California EPA (CalEPA) in 1991, is responsible for ensuring implementation of the California Clean Air Act (AB 2595), responding to the federal CAA, and for regulating emissions from consumer products and motor vehicles. AB 2595 mandates achievement of the maximum degree of emissions reductions possible from vehicular and other mobile sources in order to attain the state ambient air quality standards by the earliest practical date. The CARB established the California ambient air quality standards (CAAQS) for all pollutants for which the federal government has NAAQS and, in addition, establishes standards for SO 4,
visibility, hydrogen sulfide (H2S), and vinyl chloride (C2H3Cl). However, at this time, H2S and C2H3Cl are not measured at any monitoring stations in the SCAB because they are not considered to be a regional air quality problem. Generally, the CAAQS are more stringent than the NAAQS (7) (8).

Local air quality management districts, such as the SCAQMD, regulate air emissions from stationary sources such as commercial and industrial facilities. All air pollution control districts have been formally designated as attainment or non-attainment for each CAAQS.

Serious non-attainment areas are required to prepare Air Quality Management Plans (AQMP) that include specified emission reduction strategies in an effort to meet clean air goals. These plans are required to include:
• Application of Best Available Retrofit Control Technology to existing sources; • Developing control programs for area sources (e.g., architectural coatings and solvents) and indirect sources (e.g. motor vehicle use generated by residential and commercial development);
• A District permitting system designed to allow no net increase in emissions from any new or modified permitted sources of emissions;
• Implementing reasonably available transportation control measures and assuring a substantial reduction in growth rate of vehicle trips and miles traveled; • Significant use of low emissions vehicles by fleet operators; • Sufficient control strategies to achieve a 5% or more annual reduction in emissions or 15% or more in a period of three years for ROGs, NO
X, CO and PM10. However, air basins
may use alternative emission reduction strategy that achieves a reduction of less than 5% per year under certain circumstances.

AQMP
Currently, the NAAQS and CAAQS are exceeded in most parts of the SCAB. In response, the SCAQMD has adopted a series of AQMP to meet the state and federal ambient air quality standards (9). AQMPs are updated regularly in order to more effectively reduce emissions, accommodate growth, and to minimize any negative fiscal impacts of air pollution control on the economy.

APPLICABLE REGULATORY REQUIRMENTS
SCAQMD Rules that are currently applicable during construction activity for this Project include but are not limited to Rule 403 (Fugitive Dust) and Rule 1113 (Architectural Coatings) (10) (11).

SCAQMD Rule 403
This rule is intended to reduce the amount of particulate matter entrained in the ambient air as a result of anthropogenic (human- made) fugitive dust sources by requiring actions to prevent and reduce fugitive dust emissions. Rule 403 applies to any activi ty or human -made condition capable of generating fugitive dust and requires best available control measures to be applied to earth moving and grading activities. This rule is intended to reduce PM 10 emissions from any
transportation, handling, construction, or storage activity that has the potential to generate fugitive dust. PM
10 suppression techniques are summarized below.
• Portions of a construction site to remain inactive longer than a period of three months will be seeded and watered until grass cover is grown or otherwise stabilized. • All onsite roads will be paved as soon as feasible or watered periodically or chemically stabilized.
• All material transported offsite will be either sufficiently watered or securely covered to prevent excessive amounts of dust.
• The area disturbed by clearing, grading, earthmoving, or excavation operations will be minimized at all times.
• Where vehicles leave a construction site and enter adjacent public streets, the streets will be swept daily or washed down at the end of the workday to remove soil tracked onto the paved surface.

SCAQMD Rule 1113
This rule serves to limit the volatile organic compound (VOC) content of architectural coatings used on projects in the SCAQMD. Any person who supplies, sells, offers for sale, or manufactures any architectural coating for use on projects in the SCAQMD mus t comply with the current VOC standards set in this rule.

METHODOLOGY
In May 202 3, the California Air Pollution Control Officers Association (CAPCOA) in conjunction with other California air districts, including SCAQMD, released the latest version of the CalEEMod Version 2022.1 .1.20. The purpose of this model is to calculate construction -source and operational-source criteria pollutant (VOCs, NO
X, SOX, CO, PM10, and PM 2.5) and GHG emissions
from direct and indirect sources; and quantify applicable air quality and GHG reductions achieved from mitigation measures (12). Accordingly, the latest version of CalEEMod has been used for this Project to determine construction and operational air quality and greenhouse gas emissions.

Standards of Significance
The criteria used to determine the significance of potential Project-related air quality impacts are taken from the California Environmental Quality Act Guidelines ( CEQA Guidelines ) (14 CCR Alan Fleming, AF Properties, LLC
July 22, 2024

Page 9 of 36 ends

15715-03 AQ & GHG Assessment
§§15000, et seq.). Based on these thresholds, a project would result in a significant impact related to air quality if it would (13):
• Threshold 1: Conflict with or obstruct implementation of the applicable air quality plan. • Threshold 2: Result in a cumulatively considerable net increase of any criteria pollutant for which the project region is in non -attainment under an applicable federal or state ambient air quality standard.
• Threshold 3: Expose sensitive receptors to substantial pollutant concentrations. • Threshold 4 : Result in other emissions (such as those leading to odors) adversely affecting a substantial number of people.

AIR QUALITY REGIONAL EMISSIONS THRESHOLDS
The SCAQMD has developed regional significance thresholds for criteria pollutants, as summarized at Table 1 (14). The SCAQMD’s CEQA Air Quality Significance Thresholds ( March 2023) indicate that any projects in the South Coast Air Basin (SCAB) with daily emissions that exceed any of the indicated thresholds should be considered as having an individually and cumulatively significant air quality impact.

TABLE 1: MAXIMUM DAILY REGIONAL EMISSIONS THRESHOLDS

lbs/day – Pounds Per Day

AIR QUALITY LOCALIZED EMISSIONS THRESHOLDS
For this Project, the appropriate SRA for the LST analysis is the SCAQMD Lake Elsinore monitoring station (SRA 25). LSTs apply to CO, NO2, PM10, and PM2.5. The SCAQMD produced look-up tables for projects less than or equal to 5 acres in size . The SCAQMD’s screening look- up tables are utilized in determining localized impacts. It should be noted that since the look-up tables identify thresholds at only 1 acre, 2 acres, and 5 acres, linear regression has been utilized to determine localized significance thresholds. Consistent with SCAQMD guidance, the thresholds presented in Table 2 were calculated by interpolating the threshold values for the Project’s disturbed acreage.

The acres disturbed is based on the equipment list and days in the site preparation and grading phase according to the anticipated maximum number of acres a given piece of equipment can pass over in an 8- hour workday. The equipment -specific grading rates are summarized in the CalEEMod user’s guide, Appendix A: Calculation Details for CalEEMod (15). It should be noted that Alan Fleming, AF Properties, LLC
July 22, 2024

15715-03 AQ & GHG Assessment
the disturbed area per day is representative of a piece of equipment making multiple passes over the same land area. In other words, one Rubber Tired Dozer can make multiple passes over the same land area totaling 0.5 acres in a given 8-hour day. Appendix A of the CalEEMod User Manual only identifies equipment -specific grading rates for Crawler Tractors, Graders, Rubber Tired Dozers, and Scrapers; therefore, Tractors/Loaders/Backhoes equipment that was included in the demolition, site preparation and grading phase was replaced with Crawler Tractors. For analytical purposes, emissions associated with peak site preparation and grading activities are considered for purposes of localized significance thresholds (LSTs) since this phase represents the maximum localized emissions that would occur. The Project’s construction activities could disturb a maximum of approximately 1.5 acres per day for site preparation and 2 acres per day for grading activities. Any other construction phases of development would result in lesser emissions and consequently lesser impacts than what is disclosed herein. As such, Table 2 presents thresholds for localized construction and operational emissions.

CONSTRUCTION ACTIVITIES
Construction activities associated with the Project would result in emissions of VOCs, NO X, SOX, CO, PM10, and PM2.5. Construction related emissions are expected from the following construction activities:
• Site Preparation
• Grading (Import/Export)
• Building Construction
• Paving
• Architectural Coating

GRADING ACTIVITIES
Dust is typically a major concern during grading activities. Because such emissions are not amenable to collection and discharge through a controlled source, they are called “fugitive emissions”. Fugitive dust emissions rates vary as a function of many par ameters (soil silt, soil moisture, wind speed, area disturbed, number of vehicles, depth of disturbance or excavation, etc.). CalEEMod was utilized to calculate fugitive dust emissions resulting from this phase of activity. Per client provided data, the Project would require 2,500 cubic yards of export for Alan Fleming, AF Properties, LLC

Page 11 of 36 ends

15715-03 AQ & GHG Assessment
earthwork activities. The CalEEMod default trip length of 20- miles will be used to analyze the emissions associated with export activities.

ON-ROAD TRIPS
Construction generates on-road vehicle emissions from vehicle usage for workers, vendors, and haul trucks commuting to and from the site. Worker and hauling trips are based on CalEEMod defaults. It should be noted that for vendor trips, specifically, CalEEMod only assigns vendor trips to the Building Construction phase. Vendor trips would likely occur during all phases of construction. As such, the CalEEMod d efaults for vendor trips have been adjusted based on a ratio of the total vendor trips to the number of days of each subphase of activity.

CONSTRUCTION DURATION
For purposes of analysis, construction of Project is expected to commence in April 2024 and would last through November 2024. The construction schedule utilized in the analysis represents a “worst-case” analysis scenario should construction occur any time after the respective dates since emission factors for construction decrease as time passes and the analysis year increases due to emission regulations becoming more stringent

2. The duration of construction activity and
associated equipment represents a reasonable approximation of the expected construction fleet as required per CEQA Guidelines (16).

CONSTRUCTION EQUIPMENT
CalEEMod default parameters for equipment has been used. Consistent with industry standards and typical construction practices, each piece of equipment will operate up to a total of eight (8) hours per day, or more than two -thirds of the period during which construction activities are allowed pursuant to the code.

OFF-SITE PROJECT SITE UTILITY AND INFRASTRUCTURE IMPROVEMENTS To support the Project development, there will be off -site improvements associated with street improvements and underground utilities . It is expected that the off -site construction activities would not take place at one location for the entire duration of construction. Impacts associated with these activities are not expected to exceed the emissions identified for Project -related construction activities since the off-site construction areas would have physical constraints such as, roadway travel lanes, traf fic signals, and sidewalks which would limit the amount of daily activity that could occur. The physical constraints would limit the amount of construction equipment that could be used, and any off-site and utility infrastructure construction would not use equipment totals that would exceed the equipment totals.

2 As shown in the CalEEMod User’s Guide Version 2022.1, Section 4.3 “Off-Road Equipment” as the analysis year increases, emission factors for the same equipment pieces decrease due to the natural turnover of older equipment being replaced by newer less polluting equipment and new regulatory requirements.

REGIONAL CONSTRUCTION EMISSIONS SUMMARY
The estimated maximum daily construction emissions are summarized on Table 3, and as shown, the Project construction-source emissions would not exceed SCAQMD regional thresholds. Thus, the Project would result in a less than significant impact associated with construction activities.

Detailed construction model outputs are presented in Attachment A.

REGIONAL OPERATIONAL EMISSIONS
Operational activities associated with the Project would result in emissions of VOCs, NOX, CO, SOX, PM10, and PM2.5. Operational related emissions are expected from the following primary sources:
area source emissions, energy source emissions, and mobile source emissions.

The proposed Project related operational air quality impacts derive primarily from vehicle trips generated by the Project . Trip characteristics available from the Fleming & Sons Concrete Pumping, Inc. Truck Yard Trip Generation Assessment were utilized in this analysis (17). It should be noted that the Trip Generation Assessment assumed 4+ -axle Trucks only in an effort to conduct a conservative analysis.

To determine emissions from trucks for the proposed industrial use, the analysis incorporated the SCAQMD recommended truck trip length of 39.9 miles for 4+- axle (HHDT) trucks . The trip length function for trucks in CalEEMod has been revised to 3 9.9 miles, with an assumption of 100% primary trips for the proposed industrial land use.

The estimated operation-source emissions from the Project are summarized on Table 4. Detailed operation model outputs are presented in Attachment A. As shown on Table 4, operational - source emissions would not exceed the applicable SCAQMD regional thresholds for emissions of any criteria pollutant.

SENSITIVE RECEPTORS
The analysis makes use of methodology included in the SCAQMD Final Localized Significance Threshold Methodology (LST Methodology) (18). The SCAQMD has established that impacts to air quality are significant if there is a potential to contribute or cause localized exceedances of the federal and/or state ambient air quality standards (NAAQS/CAAQS). Collectively, these are referred to as Lo calized Significance Thresholds (LSTs). The SCAQMD established LSTs in response to the SCAQMD Governing Board’s Environmental Justice Initiative I-4

3. LSTs represent
the maximum emissions from a project that will not cause or contribute to an exceedance of the most stringent applicable federal or state ambient air quality standard at the sensitive receptor.

The SCAQMD states that lead agencies can use the LSTs as another indicator of significance in its air quality impact analyses. It should be noted that SCAQMD also states that Projects that are statutorily or categorically exempt under CEQA would not be subject to LST analyses. Projects exempt from CEQA also include infill projects that meet the H&S Code provisions. As such,

3 The purpose of SCAQMD’s Environmental Justice program is to ensure that everyone has the right to equal protection from air pollution and fair access to the decision-making process that works to improve the quality of air within their communities. Further, the SCAQMD defines Environmental Justice as “…equitable environmental policymaking and enforcement to protect the health of all residents, regardless of age, culture, ethnicity, gender, race, socioeconomic status, or geographic location, from the health effects of air pollution.” Alan Fleming, AF Properties, LLC
July 22, 2024

Page 14 of 36 ends

15715-03 AQ & GHG Assessment
although not required for this Project, LST analysis is presented to further underscore that there are in fact no significant impacts associated with the Project.

The SCAQMD recommends that the nearest sensitive receptor be considered when determining the Project’s potential to cause an individual or cumulatively significant impact. The nearest land use where an individual could remain for 24 hours to the Project site has been used to determine localized construction and operational air quality impacts for emissions of PM 10 and PM2.5 (since
PM10 and PM2.5 thresholds are based on a 24-hour averaging time). The nearest receptor used for evaluation of localized impacts of PM 10 and PM 2.5 is location R1, represented by the existing residence at 508-C North Langstaff St, approximately 355 feet (108 meters) west of the Project site. Receptors in the Project study area shown on Exhibit 2.

As previously stated, and consistent with LST Methodology, the nearest industrial/commercial use to the Project site is used to determine construction and operational LST air impacts for emissions of NO
X and CO as the averaging periods for these pollutants are shorter (8 hours or less) and it is reasonable to assume that an individual could be present at these sites for periods of one to 8 hours. The nearest receptor used for evaluation of localized impacts of NO X and CO is location R3, represented by an existing light industrial commercial building at 522 North Riley St, approximately 61 feet (19 meters) east of the Project site.

It should be noted that the LST Methodology explicitly states that “It is possible that a project may have receptors closer than 25 meters. Projects with boundaries located closer than 25 meters to the nearest receptor should use the LSTs for receptors located at 25 meters (18).” As such, for evaluation of localized NOx and CO, a 25-meter distance will be used.

LOCALIZED CONSTRUCTION EMISSIONS
Table 5 identifies the localized impacts at the nearest receptor location in the vicinity of the Project. Outputs from the model runs for construction LSTs are provided in Attachment A. For analytical purposes, emissions associated with peak site preparation and grading activities are considered for purposes of LSTs since these phases represents the maximum localized emissions that would occur. Any other construction phases of development that overlap would result in less emissions and consequently less impacts than what is disclosed herein. As shown in Table 5, emissions resulting from the Project construction will not exceed the numerical thresholds of significance established by the SCAQMD for any criteria pollutant . Thus, a less than significant impact would occur for localized Project-related construction-source emissions and no mitigation is required.

Table 6 identifies the localized operational impacts at the nearest receptor location in the vicinity of the Project. In an effort to establish a maximum potential impact scenario for analytical purposes, the emissions shown on Table 6 represent all on-site Project-related stationary (area) sources and on-site mobile source emissions. It should be noted that the longest on-site distance is roughly 0.16 miles for both trucks and passenger vehicles. As such, a separate CalEEMod run for operational LSTs has been prepared which accounts for the 0.16-mile on-site travel distance.

Outputs from the model runs for operational LSTs are provided in Attachment B. As shown in Table 6, emissions resulting from the Project operation will not exceed the numerical localized thresholds of significance established by the SCAQMD for any criteria pollutant. Thus, a less than significant impact would occur for localized Project-related operational-source emissions and no mitigation is required.

AIR QUALITY IMPACTS – CONSISTENCY WITH THRESHOLD NO. 1
Would the Project conflict with or obstruct implementation of the applicable air quality plan? The Project site is located within the SCAB, which is characterized by relatively poor air quality.

The SCAQMD has jurisdiction over an approximately 10,743 square -mile area consisting of the four-county Basin and the Los Angeles County and Riverside Coun ty portions of what use to be referred to as the Southeast Desert Air Basin. In these areas, the SCAQMD is principally responsible for air pollution control, and works directly with the Southern California Association of Governments (SCAG), county transportation commissions, local governments, as well as state and federal agencies to reduce emissions from stationary, mobile, and indirect sources to meet state and federal ambient air quality standards.

Currently, these state and federal air quality standards are exceeded in most parts of the SCAB.

In response, the SCAQMD has adopted a series of AQMPs to meet the state and federal ambient air quality standards. AQMPs are updated regularly in order to more effectively reduce emissions, accommodate growth, and to minimize any negative fiscal impacts of air pollution control on the economy.

In December 2022, the SCAQMD released the Final 2022 AQMP (2022 AQMP). The 2022 AQMP continues to evaluate current integrated strategies and control measures to meet the CAAQS, as well as explore new and innovative methods to reach its goals. Some of these approaches include utilizing incentive programs, recognizing existing co -benefit programs from other sectors, and developing a strategy with fair-share reductions at the federal, state, and local levels (19). Similar to the 201 6 AQMP, the 2022 AQMP incorporates scientific and technological information and planning assumptions, including the 2020-2045 RTP/SCS, a planning document that supports the integration of land use and transportation to help the region meet the federal CAA requirements (20). The Project’s consistency with the AQMP will be determined using the 2022 AQMP as discussed below.

Criteria for determining consistency with the AQMP are defined in Chapter 12, Section 12.2 and Section 12.3 of the 1993 CEQA Handbook (21). These indicators are discussed below.

The proposed Project will not result in an increase in the frequency or severity of existing air quality violations or cause or contribute to new violations or delay the timely attainment of air quality standards or the interim emissions reductions specified in the AQMP.

The violations that under this criterion refer to are the CAAQS and NAAQS. CAAQS and NAAQS violations would occur if regional or localized significance thresholds were exceeded.

Alan Fleming, AF Properties, LLC
July 22, 2024

Page 18 of 36 ends

15715-03 AQ & GHG Assessment
CAAQS and NAAQS violations would occur if regional or localized significance thresholds were exceeded. As evaluated, the Project’s regional and localized construction and operational-source emissions would not exceed applicable regional significance thresh olds. As such, a less than significant impact is expected.

On the basis of the preceding discussion, the Project is determined to be consistent with the first criterion.

The Project will not exceed the assumptions in the AQMP based on the years of Project build - out phase.

The 2022 AQMP demonstrates that the applicable ambient air quality standards can be achieved within the timeframes required under federal law. Growth projections from local general plans adopted by cities in the district are provided to the SCAG, which develops re gional growth forecasts, which are then used to develop future air quality forecasts for the AQMP. Development consistent with the growth projections in City of Lake Elsinore General Plan is considered to be consistent with the AQMP.

Peak day emissions generated by construction activities are largely independent of land use assignments, but rather are a function of development scope and maximum area of disturbance.

Irrespective of the site’s land use designation, development of the site to its maximum potential would likely occur, with disturbance of the entire site occurring during construction activities. As such, when considering that no emissions thresholds will be exceeded, a less than significant impact would result.

The City of Lake Elsinore General Plan designates the Project site as “ Historic District Business Professional” for APNs 377-232-006, -007, and -009. The “Historic District Business Professional” designation provides for office and administrative uses, light industrial, research and development, office-based firms, including office support facilities, restaurants, medical clinics, public and quasi-public uses, and similar compatible uses. This designation allows for a maximum FAR of 0.45 (22).

The zoning designation for the Project site is “M -1 Limited Manufacturing District,” which allows for light industrial uses that are relatively free of nuisance or hazardous characteristics and protect these areas from intrusion by residential, commercial, and other inharmonious uses.

The proposed Project includes the development of a concrete pumping truck storage yard, minor maintenance, and administrative office building of approximately 7,500 square feet on a currently vacant 1.5-acre site. As previously stated, the Project is consistent with the current land use and zoning designation. As such, the proposed Project would not conflict with the goals and objectives of the AQMP. Furthermore, the Project, as evaluated herein would not exceed the regional or localized air quality significance thresholds.

On the basis of the preceding discussion, the Project is determined to be consistent with the AQMP and a less than significant impact is expected.

AIR QUALITY IMPACTS – CONSISTENCY WITH THRESHOLD NO. 2
Would the Project result in a cumulatively considerable net increase of any criteria pollutant for which the project region is in non-attainment under an applicable federal or state ambient air quality standard?
The CAAQS designate the Project site as nonattainment for O3, PM10, and PM2.5 while the NAAQS designates the Project site as nonattainment for O3 and PM2.5.

The SCAQMD has published a report on how to address cumulative impacts from air pollution:

White Paper on Potential Control Strategies to Address Cumulative Impacts from Air Pollution (23). In this report the SCAQMD clearly states (Page D-3):
“…the SCAQMD uses the same significance thresholds for project specific and cumulative impacts for all environmental topics analyzed in an Environmental Assessment or EIR. The only case where the significance thresholds for project specific and cumulative impacts differ is the Hazard Index (HI) significance threshold for TAC emissions. The project specific (project increment) significance threshold is HI > 1.0 while the cumulative (facility- wide) is HI > 3.0. It should be noted that the HI is only one of three TAC emission significance thresholds considered (when applicable) in a CEQA analysis. The other two are the maximum individual cancer risk (MICR) and the cancer burden, both of which use the same significance thresholds (MICR of 10 in 1 million and cancer burden of 0.5) for project specific and cumulative impacts.

Projects that exceed the project-specific significance thresholds are considered by the SCAQMD to be cumulatively considerable. This is the reason project-specific and cumulative significance thresholds are the same. Conversely, projects that do not exceed the project-specific thresholds are generally not considered to be cumulatively significant.” Therefore, this analysis assumes that individual projects that do not generate operational or construction emissions that exceed the SCAQMD’s recommended daily thresholds for project - specific impacts would also not cause a cumulatively considerable increase in emissions for those pollutants for which SCAB is in nonattainment, and, therefore, would not be considered to have a significant, adverse air quality impact. Alternatively, individual project-related construction and operational emissions that exceed SCAQMD thresholds for project -specific impacts would be considered cumulatively considerable.

Construction Impacts
The Project‐specific evaluation of emissions presented in the preceding analysis demonstrates that proposed Project construction -source air pollutant emissions would not result in exceedances of regional thresholds. Therefore, proposed Project construction-source emissions would be considered less than significant on a project-specific and cumulative basis.

Operational Impacts
The Project‐specific evaluation of emissions presented in the preceding analysis demonstrates that proposed Project operational-source air pollutant emissions would not result in exceedances of regional thresholds. Therefore, the proposed Project operational-source emissions would be considered less than significant on a project-specific and cumulative basis.

Would the expose sensitive receptors to substantial pollutant concentrations? The potential impact of Project-generated air pollutant emissions at sensitive receptors has also been considered. Results of the LST analysis indicate that the Project will not exceed the SCAQMD localized significance thresholds during construction. Therefore, sensitive receptors would not be exposed to substantial pollutant concentrations during Project construction.

Additionally, the Project will not exceed the SCAQMD localized significance thresholds during operational activity. Therefore, sensitive receptors would not be exposed to substantial pollutant concentrations as the result of Project operations.

CO “HOT SPOT” ANALYSIS
As discussed below, the Project would not result in potentially adverse CO concentrations or “hot spots.” An adverse CO concentration, known as a “hot spot”, would occur if an exceedance of the state one-hour standard of 20 ppm or the eight-hour standard of 9 ppm were to occur.

It has long been recognized that CO hotspots are caused by vehicular emissions, primarily when idling at congested intersections. In response, vehicle emissions standards have become increasingly stringent in the last twenty years. Currently, the allowable CO emissions standard in California is a maximum of 3.4 grams/mile for passenger cars (there are requirements for certain vehicles that are more stringent). With the turnover of older vehicles, introduction of cleaner fuels, and implementation of increasingly sophisticated and efficient emissions control technologies, CO concentration in the SCAB is now designated as attainment.

To establish a more accurate record of baseline CO concentrations affecting the SCAB, a CO “hot spot” analysis was conducted in 2003 for four busy intersections in Los Angeles at the peak morning and afternoon time periods

4. This “hot spot” analysis did not predict any exceedance of the 1-hour (20.0 ppm) or 8-hour (9.0 ppm) CO standards, as shown on Table 7.

Long Beach Boulevard/Imperial Highway 3 3.1 8.4
Notes: Federal 1-hour standard is 35 ppm and the deferral 8-hour standard is 9.0 ppm.

Based on the SCAQMD's 2003 AQMP and the 1992 Federal Attainment Plan for Carbon Monoxide (1992 CO Plan ), peak carbon monoxide concentrations in the SCAB were a result of unusual meteorological and topographical conditions and not a result of traffic volumes and congestion

4 The CO “hot spot” analysis conducted in 2003 is the most current study used for CO “hot spot” analysis in the SCAB.

at a particular intersection. As evidence of this, for example, of the 8.4 ppm 8-hr CO concentration measured at the Long Beach Blvd. and Imperial Hwy. intersection (i.e., the highest CO generating intersection within the “hot spot” analysis), only 0.7 ppm was attributable to the traffic volumes and congestion at this intersection; the remaining 7.7 ppm were due to the ambient air measurements at the time the 2003 AQMP was prepared (24) . In contrast, an adverse CO concentration, known as a “hot spot”, would occur if an exceedance of the state one -hour standard of 20 parts per million (ppm) or the eight-hour standard of 9 ppm were to occur.

The ambient 1-hr and 8-hr CO concentration within the Project study area is estimated to be 0.9 ppm and 0.6 ppm, respectively (data from Lake Elsinore Area monitoring station for 202 2).

Therefore, even if the traffic volumes for the proposed Project were ten times the traffic volumes generated at the Long Beach Blvd. and Imperial Hwy. intersection, due to the on -going improvements in ambient air quality and vehicular emissions controls, the Project would not be capable of resulting in a CO “hot spot” at any study area intersections. As noted above, only 0.7 ppm were attributable to the traffic volumes and congestion at one of the busiest intersec tions in the SCAB. Therefore, if these traffic volumes were multiplied by ten times, it could be expected that the CO attributable to traffic would increase tenfold as well, resulting in 7 ppm – even if this were added to either the 1-hour or 8-hour CO concentrations within the Project study area, this would result in 7.9 ppm and 7.6 ppm for the 1 -hr and 8-hr timeframes, respectively. Neither of which would exceed the applicable 1-hr standard of 20 ppm or the 8-hr standard of 9 ppm.

Similar considerations are also employed by other Air Districts when evaluating potential CO concentration impacts. More specifically, the Bay Area Air Quality Management District (BAAQMD) concludes that under existing and future vehicle emission rates, a given project would have to increase traffic volumes at a single intersection by more than 44,000 vehicles per hour (vph)—or 24,000 vph where vertical and/or horizontal air does not mix —in order to generate a significant CO impact (25). Traffic volumes generating the CO concentrations for the “hot spot” analysis is shown on Table 8. The busiest intersection evaluated was that at Wilshire Boulevard and Veteran Avenue, which had AM/PM traffic volumes of 8,062 vph and 7,719 vph respectively (24)

Would the Project result in other emissions (such as those leading to odors) adversely affecting a substantial number of people?
The potential for the Project to generate objectionable odors has also been considered. Land uses generally associated with odor complaints include:
• Agricultural uses (livestock and farming)
• Wastewater treatment plants
• Food processing plants
• Chemical plants
• Composting operations
• Refineries
• Landfills
• Dairies
• Fiberglass molding facilities
The Project does not contain land uses typically associated with emitting objectionable odors.

Potential odor sources associated with the proposed Project may result from construction equipment exhaust and the application of asphalt and architectural coatings during construction activities and the temporary storage of typical solid waste (refuse) associated with the proposed Project’s (long-term operational) uses. Standard construction requirements would minimize odor impacts from construction. The construction odor emissions would be temporary, short -term, and intermittent in nature and would cease upon completion of the respective phase of construction and is thus considered less than significant. It is expected that Project -generated refuse would be stor ed in covered containers and removed at regular intervals in compliance with the solid waste regulations. The proposed Project would also be required to comply with SCAQMD Rule 402 to prevent occurrences of public nuisances. Therefore, odors associated with the proposed Project construction and operations would be less than significant and no mitigation is required (26).

PROJECT GHG ANALYSIS

CLIMATE CHANGE SETTING
Global climate change (GCC) is the change in average meteorological conditions on the earth with respect to temperature, precipitation, and storms. The majority of scientists believe that the climate shift taking place since the Industrial Revolution is occurring at a quicker rate and magnitude than in the past. Scientific evidence suggests that GCC is the result of increased concentrations of GHGs in the earth’s atmosphere, including carbon di oxide (CO 2), methane
(CH4), nitrous oxide (N 2O), and fluorinated gases. The majority of scientists believe that this increased rate of climate change is the result of GHGs resulting from human activity and industrialization over the past 200 years.

An individual project like the proposed Project evaluated in this memo cannot generate enough GHG emissions to affect a discernible change in global climate. However, the proposed Project may participate in the potential for GCC by its incremental contribution of GHGs combined with the cumulative increase of all other sources of GHGs, which when taken together constitute potential influences on GCC. Because these changes may have serious environmental consequences, this memo will evaluate the potential for the proposed Project to have a significant effect upon the environment as a result of its potential contribution to the greenhouse effect.

GCC refers to the change in average meteorological conditions on the earth with respect to temperature, wind patterns, precipitation and storms. Global temperatures are regulated by naturally occurring atmospheric gases such as water vapor, CO 2, N2O, CH4, hydrofluorocarbons
(HFCs), perfluorocarbons (PFCs), and sulfur hexafluoride (SF 6). These particular gases are important due to their residence time (duration they stay) in the atmosphere, which ranges from 10 years to more than 100 years. These gases allow solar radiation into the earth’s atmosphere, but prevent radiative heat from escaping, thus warming the earth’s atmosphere. GCC can occur naturally as it has in the past with the previous ice ages.

Gases that trap heat in the atmosphere are often referred to as GHGs. GHGs are released into the atmosphere by both natural and anthropogenic activity. Without the natural GHG effect, the earth’s average temperature would be approximately 61 degrees Fahrenheit (°F) cooler than it is currently. The cumulative accumulation of these gases in the earth’s atmosphere is considered to be the cause for the observed increase in the earth’s temperature.

For the purposes of this analysis, emissions of CO
2, CH4, and N2O were evaluated because these
gases are the primary contributors to GCC from development projects. Although there are other substances such as fluorinated gases that also contribute to GCC, these fluorinated gases were not evaluated as their sources are not well-defined and do not contain accepted emissions factors or methodology to accurately calculate these gases.

REGULATORY SETTING
Executive Order S-3-05
Former California Governor Arnold Schwarzenegger announced on June 1, 2005, through Executive Order S-3-05, the following reduction targets for GHG emissions:
• By 2010, reduce GHG emissions to 2000 levels.

Alan Fleming, AF Properties, LLC
July 22, 2024

Page 24 of 36 ends

15715-03 AQ & GHG Assessment
• By 2020, reduce GHG emissions to 1990 levels.
• By 2050, reduce GHG emissions to 80% below 1990 levels.

The 2050 reduction goal represents what some scientists believe is necessary to reach levels that will stabilize the climate. The 2020 goal was established to be a mid-term target. Because this is an executive order, the goals are not legally enforceable for local governments or the private sector.

Assembly Bill (AB) 32
The California State Legislature enacted AB 32, which requires that GHGs emitted in California be reduced to 1990 levels by the year 2020. “GHGs” as defined under AB 32 include CO 2, CH4, N2O,
hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), and sulfur hexafluoride (SF6). Since AB 32 was enacted, a seventh chemical, nitrogen trifluoride, has also been added to the list of GHGs.

CARB is the state agency charged with monitoring and regulating sources of GHGs. Pursuant to AB 32, CARB adopted regulations to achieve the maximum technologically feasible and cost - effective GHG emission reductions. AB 32 states the following:
“Global warming poses a serious threat to the economic well -being, public health, natural resources, and the environment of California. The potential adverse impacts of global warming include the exacerbation of air quality problems, a reduction in the quality and supply of water to the state from the Sierra snowpack, a rise in sea levels resulting in the displacement of thousands of coastal businesses and residences, damage to marine ecosystems and the natural environment, and an increase in the incidences of infectious diseases, asthma, and other human health-related problems.”
CARB approved the 1990 GHG emissions level of 427 million metric ton of CO 2 equivalent per
year (MMTCO2e) on December 6, 2007 (27). Therefore, emissions generated in California in 2020 are required to be equal to or less than 427 MMTCO2e. Emissions in 2020 in a “business as usual” (BAU) scenario were estimated to be 596 MMTCO 2e, which do not account for reductions from AB 32 regulations (28). At that level, a 28.4% reduction was required to achieve the 427 MMTCO2e 1990 inventory. In October 2010, CARB prepared an updated BAU 2020 forecast to account for the recession and slower forecasted growth. The forecasted inventory without the benefits of adopted regulation is now estimated at 545 MMTCO
2e. Therefore, under the updated forecast, a

21.7% reduction from BAU is required to achieve 1990 levels (29).

Progress in Achieving AB 32 Targets and Remaining Reductions Required The State has made steady progress in implementing AB 32 and achieving targets included in Executive Order S -3-05. The progress is shown in updated emission inventories prepared by CARB for 2000 through 2012 (30). The State has achieved the Executive Order S- 3-05 target for 2010 of reducing GHG emissions to 2000 levels. As shown below, the 2010 emission inventory achieved this target.
• 1990: 427 MMTCO
2e (AB 32 2020 target)
• 2000: 463 MMTCO2e (an average 8% reduction needed to achieve 1990 base) • 2010: 450 MMTCO2e (an average 5% reduction needed to achieve 1990 base) Alan Fleming, AF Properties, LLC

15715-03 AQ & GHG Assessment
CARB has also made substantial progress in achieving its goal of achieving 1990 emissions levels by 2020. As described earlier in this section, CARB revised the 2020 BAU inventory forecast to account for new lower growth projections, which resulted in a new lower reduction from BAU to achieve the 1990 base. The previous reduction from 2020 BAU needed to achieve 1990 levels was 28.4% and the latest reduction from 2020 BAU is 21.7%. • 2020: 545 MMTCO
2e BAU (an average 21.7% reduction from BAU needed to achieve 1990 base)
Senate Bill (SB) 32
On September 8, 2016, Governor Jerry Brown signed the SB 32 and its companion bill, AB 197. SB 32 requires the state to reduce statewide GHG emissions to 40% below 1990 levels by 2030, a reduction target that was first introduced in Executive Order B-30-15. The new legislation builds upon the AB 32 goal of 1990 levels by 2020 and provides an intermediate goal to achieving S -3- 05, which sets a statewide GHG reduction target of 80% below 1990 levels by 2050. AB 197 creates a legislative committee to oversee r egulators to ensure that CARB not only responds to the Governor, but also the Legislature (31).

AB 197
A condition of approval for SB 32 was the passage of AB 197. AB 197 requires that CARB consider the social costs of GHG emissions and prioritize direct reductions in GHG emissions at mobile sources and large stationary sources. AB 197 also gives the California legislature more oversight over CARB through the addition of two legislatively appointed members to the CARB Board and the establishment a legislative committee to make recommendations about CARB programs to the legislature.

Executive Order B-55-18 and SB 100
Executive Order B -55-18 and SB 100. SB 100 and Executive Order B -55-18 were signed by Governor Brown on September 10, 2018. Under the existing RPS, 25% of retail sales are required to be from renewable sources by December 31, 2016, 33% by December 31, 2020 , 40% by December 31, 2024, 45% by December 31, 2027, and 50% by December 31, 2030. SB 100 raises California’s RPS requirement to 50% renewable resources target by December 31, 2026, and to achieve a 60% target by December 31, 2030. SB 100 also requires th at retail sellers and local publicly owned electric utilities procure a minimum quantity of electricity products from eligible renewable energy resources so that the total kilowatt hours of those products sold to their retail end-use customers achieve 44% of retail sales by December 31, 2024, 52% by December 31, 2027, and 60% by December 31, 2030. In addition to targets under AB 32 and SB 32, Executive Order B- 55-18 establishes a carbon neutrality goal for the state of California by 2045; and sets a goal to maintain net negative emissions thereafter. The Executive Order directs the California Natural Resources Agency (CNRA), California Environmental Protection Agency (CalEPA), the Department of Food and Agriculture (CDFA), and CARB to include sequestration t argets in the Natural and Working Lands Climate Change Implementation Plan consistent with the carbon neutrality goal.

Title 24 California Code of Regulations (CCR)
California Code of Regulations (CCR) Title 24 Part 6: The California Energy Code was first adopted in 1978 in response to a legislative mandate to reduce California’s energy consumption.

15715-03 AQ & GHG Assessment
The standards are updated periodically to allow consideration and possible incorporation of new energy efficient technologies and methods. CCR, Title 24, Part 11: California Green Building Standards Code (CALGreen) is a comprehensive and uniform regulatory code for all residential, industrial, commercial, and school buildings that went in effect on August 1, 2009, and is administered by the California Building Standards Commission.

CALGreen is updated on a regular basis, with the most recent approved update consisting of the 2022 California Green Building Code Standards that was effective on January 1, 20235. As construction of the Project is anticipated to be completed in 2024, the Project would be required to comply with the Title 24 standards in place at that time.

SCAQMD
SCAQMD is the agency responsible for air quality planning and regulation in the SCAB. The SCAQMD addresses the impacts to climate change of projects subject to SCAQMD permit as a lead agency if they are the only agency having discretionary approval for the project and acts as a responsible agency when a land use agency must also approve discretionary permits for the project. The SCAQMD acts as an expert commenting agency for impacts to air quality. This expertise carries over to GHG emissions, so the agency helps local land use agencies through the development of models and emission thresholds that can be used to address GHG emissions.

In 2008, SCAQMD formed a Working Group to identify GHG emissions thresholds for land use projects that could be used by local lead agencies in the SCAB. The Working Group developed several different options that are contained in the SCAQMD Draft Guidance Document – Interim CEQA GHG Significance Threshold, that could be applied by lead agencies. The working group has not provided additional guidance since release of the interim guidance in 2008. The SCAQMD Board has not approved the thresholds; however, the Guidance Document provides substantial evidence supporting the approaches to significance of GHG emissions that can be considered by the lead agency in adopting its own threshold. The current interim thresholds consist of the following tiered approach:
• Tier 1 consists of evaluating whether or not the project qualifies for any applicable exemption under CEQA.
• Tier 2 consists of determining whether the project is consistent with a GHG reduction plan. If a project is consistent with a qualifying local GHG reduction plan, it does not have significant GHG emissions.
• Tier 3 consists of screening values, which the lead agency can choose, but must be consistent with all projects within its jurisdiction. A project’s construction emissions are averaged over 30 years and are added to the project’s operational emissions. If a project’s emissions are below one of the following screening thresholds, then the project is less than significant:
o Residential and commercial land use: 3,000 m etric ton of CO 2 equivalent
(MTCO2e/yr)

o Industrial land use: 10,000 MTCO2e/yr
o Based on land use type: residential: 3,500 MTCO 2e/yr; commercial: 1,400 MTCO2e/yr; or mixed use: 3,000 MTCO2e/yr
• Tier 4 has the following options:
o Option 1: Reduce Business-as-Usual (BAU) emissions by a certain percentage; this percentage is currently undefined.
o Option 2: Early implementation of applicable AB 32 Scoping Plan measures o Option 3: 2020 target for service populations (SP), which includes residents and employees: 4.8 MTCO2e per SP per year for projects and 6.6 MTCO 2e per SP per year for plans;
o Option 3, 2035 target: 3.0 MTCO 2e per SP per year for projects and 4.1 MTCO 2e per SP per year for plans
• Tier 5 involves mitigation offsets to achieve target significance threshold.

The SCAQMD’s interim thresholds used the Executive Order S- 3-05-year 2050 goal as the basis for the Tier 3 screening level. Achieving the Executive Order’s objective would contribute to worldwide efforts to cap CO
2 concentrations at 450 ppm, thus stabilizing global climate.

SCAQMD only has authority over GHG emissions from development projects that include air quality permits. At this time, it is unknown if the project would include stationary sources of emissions subject to SCAQMD permits. Notwithstanding, if the Project requires a stationary permit, it would be subject to the applicable SCAQMD regulations.

SCAQMD Regulation XXVII, adopted in 2009 includes the following rules:
• Rule 2700 defines terms and post global warming potentials. • Rule 2701, Southern California (SoCal) Climate Solutions Exchange, establishes a voluntary program to encourage, quantify, and certify voluntary, high quality certified GHG emission reductions in the SCAQMD.
• Rule 2702, GHG Reduction Program created a program to produce GHG emission reductions within the SCAQMD. The SCAQMD will fund projects through contracts in response to requests for proposals or purchase reductions from other parties.

SCAQMD is the agency responsible for air quality planning and regulation in the SCAB. The SCAQMD addresses the impacts to climate change of projects subject to SCAQMD permit as a lead agency if they are the only agency having discretionary approval for the project and acts as a responsible agency when a land use agency must also approve discretionary permits for the project. The SCAQMD acts as an expert commenting agency for impacts to air quality. This expertise carries over to GHG emissions, so the agency helps local land use agencies through the development of models and emission thresholds that can be used to address GHG emissions.

CITY OF LAKE ELSINORE CLIMATE ACTION PLAN (CAP)
The City of Lake Elsinore CAP is a comprehensive document to ensure that the City reduces community-wide GHG emissions (32). The CAP was prepared concurrently with the City’s General Plan and environmental impact report (EIR), to serve as the City’s primary information and policy document for GHG emissions reductions in order to analyze and reduce potentially significant GHG emissions resulting from development under the City of Lake Elsinore General Plan.

The CAP includes a “Project-Level CAP Consistency Worksheet” to determine if further analysis is required. It should be noted that the “Project -Level CAP Consistency Worksheet” is generally applicable to traditional land use development projects . As such, pursuant to the CAP documentation, consistency with the CAP is evaluated on Table 10.

GHG IMPACTS
Standards of Significance
According to the CEQA Guidelines Appendix G thresholds, to determine whether impacts from GHG emissions are significant. Would the project:
• Threshold 1 : Generate GHG emissions, either directly or indirectly, that may have a significant impact on the environment?
• Threshold 2 : Conflict with an applicable plan, policy or regulation adopted for the purpose of reducing the emissions of GHGs?
The evaluation of an impact under CEQA requires measuring data from a project against both existing conditions and a “threshold of significance.” For establishing significance thresholds, the Office of Planning and Research’s amendments to the CEQA Guidel ines Section 15064.7(c) state “[w]hen adopting thresholds of significance, a lead agency may consider thresholds of significance previously adopted or recommended by other public agencies, or recommended by experts, provided the decision of the lead agency to adopt such thresholds is supported by substantial evidence.”
CEQA Guidelines Section 15064.4(a) further states, “. . . A lead agency shall have discretion to determine, in the context of a particular project, whether to: (1) Use a model or methodology to quantify greenhouse gas emissions resulting from a project, and which model or methodo logy to use . . .; or (2) Rely on a qualitative analysis or performance-based standards.” CEQA Guidelines Section 15064.4 provides that a lead agency should consider the following factors, among others, in assessing the significance of impacts from greenhouse gas emissions:
• Consideration #1: The extent to which the project may increase or reduce greenhouse gas emissions as compared to the existing environmental setting.

• Consideration #2: Whether the project emissions exceed a threshold of significance that the lead agency determines applies to the project.

• Consideration #3: The extent to which the project complies with regulations or requirements adopted to implement a statewide, regional, or local plan for the reduction or mitigation of greenhouse gas emissions. Such regulations or requirements must be Alan Fleming, AF Properties, LLC

Page 29 of 36 ends

15715-03 AQ & GHG Assessment
adopted by the relevant public agency through a public review process and must reduce or mitigate the project’s incremental contribution of greenhouse gas emissions. In determining the significance of impacts, the lead agency may consider a project’s consistency with the State’s long-term climate goals or strategies, provided that substantial evidence supports the agency’s analysis of how those goals or strategies address the project’s incremental contribution to climate change and its conclusion that the project’s incremental contribution is not cumulatively considerable.

Discussion on Establishment of Significance Thresholds
The City of Lake Elsinore has not adopted its own numeric threshold of significance for determining impacts with respect to project level GHG emissions. However, an acceptable approach, for small projects, is using a screening threshold of 3,000 MT CO2e/yr to determine if additional analysis is required. This approach is an accepted screening method used by the City of Lake Elsinore and numerous local agencies throughout South Coast Air Basin and is based on the SCAQMD staff’s proposed GHG screening threshold for stationary source emissions for non- industrial projects, as described in the SCAQMD’s Interim CEQA GHG Significance Threshold for Stationary Sources, Rules and Plans (“SCAQMD Interim GHG Threshold”). The SCAQMD Interim GHG Threshold identifies a screening threshold to determine whether additional analysis is required (33). As noted by the SCAQMD:
“…the…screening level for stationary sources is based on an emission capture rate of 90% for all new or modified projects...the policy objective of [SCAQMD’s] recommended interim GHG significance threshold proposal is to achieve an emission capture rate of 90% of all new or modified stationary source projects. A GHG significance threshold based on a 90% emission capture rate may be more appropriate to address the long-term adverse impacts associated with global climate change because most projects will be required to implement GHG reduction measures. Further, a 90% emission capture rate sets the emission threshold low enough to capture a substantial fraction of future stationary source projects that will be constructed to accommodate future statewide population and economic growth, while setting the emission threshold high enough to exclude small projects that will in aggregate contribute a relatively small fraction of the cumulative statewide GHG emissions. This assertion is based on the fact that [SCAQMD] staff estimates that these GHG emissions would account for slightly less than 1% of future 2050 statewide GHG emissions target (85 [MMT CO
2e/yr]). In addition, these small projects may be subject to future applicable GHG control regulations that would further reduce their overall future contribution to the statewide GHG inventory. Finally, these small sources are already subject to [Best Available Control Technology] (BACT) for criteria pollutants and are more likely to be single-permit facilities, so they are more likely to have few opportunities readily available to reduce GHG emissions from other parts of their facility.” (34)
Thus, and based on guidance from the SCAQMD, if a n industrial project would emit GHGs less than 3,000 MT CO
2e per year, the project is not considered a substantial GHG emitter and the GHG impact is less than significant, requiring no additional analysis and no mitigation. On the other hand, if an industrial project would emit GHGs in excess of 3,000 MT CO 2e/yr, then the project could be considered a substantial GHG emitter, which would require additional analysis and potentially mitigation.

Would the Project have the potential to generate direct or indirect GHG emissions that would result in a significant impact on the environment?

PROJECT GHG EMISSIONS
The estimated GHG emissions for the Project land use are summarized on Table 9. The estimated GHG emission include emissions from Carbon Dioxide (CO2), Methane (CH4), Nitrous Oxide (N2O), and Refrigerants (R). As shown on Table 9, the Project would generate a total of approximately 246.65 MTCO2e/yr. Detailed operation model outputs for the proposed Project are presented in Attachment A.

As discussed previously, the City of Lake Elsinore has not adopted its own numeric threshold of significance for determining impacts with respect to GHG emissions. A screening threshold of 3,000 MTCO2e/yr to determine if additional analysis is required is an acceptable approach for small projects. This ap proach is a widely accepted screening threshold used by the County of Riverside (35) and numerous cities in the SCAQMD staff’s proposed GHG screening threshold for stationary source emissions for non -industrial projects, as described in the SCAQMD’s Interim CEQA GHG Significance Threshold for Stationary Sources, Rules and Plans (“SCAQMD Interim GHG Threshold”). The SCAQMD Interim GHG Threshold identifies a screening threshold to determine whether additional analysis is required (34) projects that generate less than 3,000 MTCO 2e/yr would have a less-than-significant GHG emissions impact.

As shown, the proposed Project would generate a total of 246.65 MTCO2e/yr and would therefore not exceed the 3,000 MTCO2e/yr significance threshold. Thus, the Project would result in a less than significant impact with respect to GHG emissions.

GHG IMPACTS – CONSISTENCY WITH THRESHOLD NO. 2
Would the Project have the potential to conflict with any applicable plan, policy or regulation of an agency adopted for the purpose of reducing the emissions of GHGs? Pursuant to 15604.4 of the CEQA Guidelines, a lead agency may rely on qualitative analysis or performance-based standards to determine the significance of impacts from GHG emissions (36).

The 2022 Scoping Plan for Achieving Carbon Neutrality (2022 Scoping Plan) lays out a path to achieve targets for carbon neutrality and reduce anthropogenic greenhouse gas (GHG) emissions by 85 percent below 1990 levels no later than 2045, as directed by Assembly Bill 1279. The actions and outcomes in the plan will achieve significant reductions in fossil fuel combustion by deploying clean technologies and fuels, further reductions in short -lived climate pollutants, support for sustainable development, increased action on natural and working lands to reduce emissions and sequester carbon, and the capture and storage of carbon (37).

Additionally, the Project will result in approximately 246.65 MTCO 2e/yr and would not exceed the
screening threshold of 3,000 MTCO 2e/yr. Thus, Project -related emissions would not have a significant direct or indirect impact on GHG and climate change and would comply with the City’s GHG policies under the CAP without mitigation as shown on Table 10. Overall, the proposed Project would not conflict with the City’s CAP and impacts would be less than significant.

Finally, the Project is consistent with the general plan land use designation, density, building intensity, and applicable policies specified for the Project area in SCAG's Sustainable Community Strategy/ Regional Transportation Plan, which pursuant to SB 375 calls for the integration of transportation, land -use and housing policies to plan for achievement of the GHG -emissions target for the region. Thus, a less than significant impact related to GHG emissions from Project construction and operation would occur and no mitigation is required.

CONSISTENCY WITH CITY OF LAKE ELSINORE CAP
The City’s CAP, adopted in 2011, certified that the City’s target is consistent with AB 32’s 2020 goals. Although the Project will be completed post -2020, at the time this analysis was prepared, an updated CA P has not been formally adopted. The following table consists of an analysis of Project consistency with the policies in the CAP.

6. Climate Risk Detailed Report

6.1. Climate Risk Summary
Cal-Adapt midcentury 2040–2059 average projections for four hazards are reported below for your project location. These are under Representation Concentration Pathway (RCP) 8.5 which assumes GHG emissions will continue to rise strongly through 2050 and then plateau around 2100.

Climate Hazard Result for Project Location Unit
Temperature and Extreme Heat 27.9 annual days of extreme heat Extreme Precipitation 4.25 annual days with precipitation above 20 mm Sea Level Rise — meters of inundation depth
Wildfire 16.6 annual hectares burned
Temperature and Extreme Heat data are for grid cell in which your project are located. The projection is based on the 98th historical percentile of daily maximum/minimum temperatures from observed historical data (32 climate model ensemble from Cal-Adapt, 2040–2059 average under RCP 8.5). Each grid cell is 6 kilometers (km) by 6 km, or 3.7 miles (mi) by 3.7 mi.

Extreme Precipitation data are for the grid cell in which your project are located. The threshold of 20 mm is equivalent to about ¾ an inch of rain, which would be light to moderate rainfall if received over a full day or heavy rain if received over a period of 2 to 4 hours. Each grid cell is 6 kilometers (km) by 6 km, or 3.7 miles (mi) by 3.7 mi.

Sea Level Rise data are for the grid cell in which your project are located. The projections are from Radke et al. (2017), as reported in Cal-Adapt (Radke et al., 2017, CEC-500-2017-008), and consider inundation location and depth for the San Francisco Bay, the Sacramento-San Joaquin River Delta and California coast resulting different increments of sea level rise coupled with extreme storm events.

Users may select from four scenarios to view the range in potential inundation depth for the grid cell. The four scenarios are: No rise, 0.5 meter, 1.0 meter, 1.41 meters Wildfire data are for the grid cell in which your project are located. The projections are from UC Davis, as reported in Cal-Adapt (2040–2059 average under RCP 8.5), and consider historical data of climate, vegetation, population density, and large (> 400 ha) fire history. Users may select from four model simulations to view the range in potential wildfire probabilities for the grid cell. The four simulations make different assumptions about expected rainfall and temperature are: Warmer/drier (HadGEM2-ES), Cooler/wetter (CNRM-CM5), Average conditions (CanESM2), Range of different rainfall and temperature possibilities (MIROC5). Each grid cell is 6 kilometers (km) by 6 km, or 3.7 miles (mi) by 3.7 mi.
