1 INTRODUCTION
This noise analysis has been completed to determine the noise impacts associated with the
development of the proposed Slover Avenue and Cypress Avenue Warehouse (“Project”). This
noise study briefly describes the proposed Project, provides information regarding noise
fundamentals, sets out the local regulatory setting, presents the study methods and procedures
for transportation related CNEL traffic noise analysis, and evaluates the future exterior noise
environment. In addition, this study includes an analysis of the potential Project-related long-
term stationary-source operational noise and short-term construction noise and vibration
impacts.
1.1 SITE LOCATION
The proposed project is located on the northwest corner of Cypress Avenue and Slover Avenue
in the City of Fontana. The Project location is shown on Exhibit 1-A. The Project Site is generally
located directly south of the I-10 Freeway with the nearest noise sensitive residential uses
located south and west of the Project site.
1.2 PROJECT DESCRIPTION
The proposed Project includes the development of 469,095 square feet of high-cube fulfillment
center warehouse use (75% of the total square footage) and 156,365 square feet of high-cube
cold storage warehouse use (25% of the total square footage) for a total of 625,460 square feet,
as shown on Exhibit 1-B. The Project is anticipated to be developed within a single phase with an
Opening Year of 2023.
To present the potential worst-case conditions, the Project is assumed to be operational 24 hours
per day, seven days per week. It is expected that the Project business operations would primarily
be conducted within the enclosed buildings, except for traffic movement, parking, as well as
loading and unloading of trucks at designated loading bays. The on-site Project-related noise
sources are expected to include: loading dock activity, roof-top air conditioning units, parking lot
vehicle movements, trash enclosure activity, and truck movements.
Per the Slover Avenue and Cypress Avenue Warehouse Traffic Study prepared by Urban
Crossroads, Inc., the Project is expected to generate a total of approximately 1,334 vehicular trips
per day, which includes 296 truck trips per day (2).

2 FUNDAMENTALS
Noise is simply defined as "unwanted sound." Sound becomes unwanted when it interferes with
normal activities, when it causes actual physical harm or when it has adverse effects on health.
Noise is measured on a logarithmic scale of sound pressure level known as a decibel (dB). A-
weighted decibels (dBA) approximate the subjective response of the human ear to broad
frequency noise source by discriminating against very low and very high frequencies of the
audible spectrum. They are adjusted to reflect only those frequencies which are audible to the
human ear. Exhibit 2-A presents a summary of the typical noise levels and their subjective
loudness and effects that are described in more detail below.
EXHIBIT 2-A: TYPICAL NOISE LEVELS
Source: Environmental Protection Agency Office of Noise Abatement and Control, Information on Levels of Environmental Noise
Requisite to Protect Public Health and Welfare with an Adequate Margin of Safety (EPA/ONAC 550/9-74-004) March 1974.
2.1 RANGE OF NOISE
Since the range of intensities that the human ear can detect is so large, the scale frequently used
to measure intensity is a scale based on multiples of 10, the logarithmic scale. The scale for
measuring intensity is the decibel scale. Each interval of 10 decibels indicates a sound energy ten
times greater than before, which is perceived by the human ear as being roughly twice as loud.
(3) The most common sounds vary between 40 dBA (very quiet) to 100 dBA (very loud). Normal
conversation at three feet is roughly at 60 dBA, while loud jet engine noises equate to 110 dBA
Slover Avenue and Cypress Avenue Warehouse Noise Impact Analysis
13921-06 Noise Study
8
at approximately 100 feet, which can cause serious discomfort. (4) Another important aspect of
noise is the duration of the sound and the way it is described and distributed in time.
2.2 NOISE DESCRIPTORS
Environmental noise descriptors are generally based on averages, rather than instantaneous,
noise levels. The most used figure is the equivalent level (Leq). Equivalent sound levels are not
measured directly but are calculated from sound pressure levels typically measured in A-
weighted decibels (dBA). The equivalent sound level (Leq) represents a steady state sound level
containing the same total energy as a time varying signal over a given sample period (typically
one hour) and is commonly used to describe the “average” noise levels within the environment.
Peak hour or average noise levels, while useful, do not completely describe a given noise
environment. Noise levels lower than peak hour may be disturbing if they occur during times
when quiet is most desirable, namely evening and nighttime (sleeping) hours. To account for
this, the Community Noise Equivalent Level (CNEL), representing a composite 24-hour noise level
is utilized. The CNEL is the weighted average of the intensity of a sound, with corrections for time
of day, and averaged over 24 hours. The time of day corrections require the addition of 5 decibels
to dBA Leq sound levels in the evening from 7:00 p.m. to 10:00 p.m., and the addition of 10
decibels to dBA Leq sound levels at night between 10:00 p.m. and 7:00 a.m. These additions are
made to account for the noise sensitive time periods during the evening and night hours when
sound appears louder. CNEL does not represent the actual sound level heard at any time, but
rather represents the total sound exposure. The City of Fontana relies on the 24-hour CNEL level
to assess land use compatibility with transportation related noise sources.
2.3 SOUND PROPAGATION
When sound propagates over a distance, it changes in level and frequency content. The way noise
reduces with distance depends on the following factors.
2.3.1 GEOMETRIC SPREADING
Sound from a localized source (i.e., a stationary point source) propagates uniformly outward in a
spherical pattern. The sound level attenuates (or decreases) at a rate of 6 dB for each doubling
of distance from a point source. Highways consist of several localized noise sources on a defined
path and hence can be treated as a line source, which approximates the effect of several point
sources. Noise from a line source propagates outward in a cylindrical pattern, often referred to
as cylindrical spreading. Sound levels attenuate at a rate of 3 dB for each doubling of distance
from a line source. (3)
2.3.2 GROUND ABSORPTION
The propagation path of noise from a highway to a receiver is usually very close to the ground.
Noise attenuation from ground absorption and reflective wave canceling adds to the attenuation
associated with geometric spreading. Traditionally, the excess attenuation has also been
expressed in terms of attenuation per doubling of distance. This approximation is usually
Slover Avenue and Cypress Avenue Warehouse Noise Impact Analysis
13921-06 Noise Study
9
sufficiently accurate for distances of less than 200 ft. For acoustically hard sites (i.e., sites with a
reflective surface between the source and the receiver, such as a parking lot or body of water),
no excess ground attenuation is assumed. For acoustically absorptive or soft sites (i.e., those
sites with an absorptive ground surface between the source and the receiver such as soft dirt,
grass, or scattered bushes and trees), an excess ground attenuation value of 1.5 dB per doubling
of distance is normally assumed. When added to the cylindrical spreading, the excess ground
attenuation results in an overall drop-off rate of 4.5 dB per doubling of distance from a line
source. (5)
2.3.3 ATMOSPHERIC EFFECTS
Receivers located downwind from a source can be exposed to increased noise levels relative to
calm conditions, whereas locations upwind can have lowered noise levels. Sound levels can be
increased at large distances (e.g., more than 500 feet) due to atmospheric temperature inversion
(i.e., increasing temperature with elevation). Other factors such as air temperature, humidity,
and turbulence can also have significant effects. (3)
2.3.4 SHIELDING
A large object or barrier in the path between a noise source and a receiver can substantially
attenuate noise levels at the receiver. The amount of attenuation provided by shielding depends
on the size of the object and the frequency content of the noise source. Shielding by trees and
other such vegetation typically only has an “out of sight, out of mind” effect. That is, the
perception of noise impact tends to decrease when vegetation blocks the line-of-sight to nearby
residents. However, for vegetation to provide a substantial, or even noticeable, noise reduction,
the vegetation area must be at least 15 feet in height, 100 feet wide and dense enough to
completely obstruct the line-of sight between the source and the receiver. This size of vegetation
may provide up to 5 dBA of noise reduction. The Federal Highway Administration (FHWA) does
not consider the planting of vegetation to be a noise abatement measure. (5)
2.3.5 REFLECTION
Field studies conducted by the FHWA have shown that the reflection from barriers and buildings
does not substantially increase noise levels. (5) If all the noise striking a structure was reflected
back to a given receiving point, the increase would be theoretically limited to 3 dBA. Further, not
all the acoustical energy is reflected back to same point. Some of the energy would go over the
structure, some is reflected to points other than the given receiving point, some is scattered by
ground coverings (e.g., grass and other plants), and some is blocked by intervening structures
and/or obstacles (e.g., the noise source itself). Additionally, some of the reflected energy is lost
due to the longer path that the noise must travel. FHWA measurements made to quantify
reflective increases in traffic noise have not shown an increase of greater than 1-2 dBA; an
increase that is not perceptible to the average human ear.
2.4 NOISE CONTROL
Noise control is the process of obtaining an acceptable noise environment for an observation
point or receiver by controlling the noise source, transmission path, receiver, or all three. This
Slover Avenue and Cypress Avenue Warehouse Noise Impact Analysis
13921-06 Noise Study
10
concept is known as the source-path-receiver concept. In general, noise control measures can
be applied to these three elements.
2.5 NOISE BARRIER ATTENUATION
Effective noise barriers can reduce noise levels by up to 10 to 15 dBA, cutting the loudness of
traffic noise in half. A noise barrier is most effective when placed close to the noise source or
receiver. Noise barriers, however, do have limitations. For a noise barrier to work, it must be
high enough and long enough to block the path of the noise source. (5)
2.6 LAND USE COMPATIBILITY WITH NOISE
Some land uses are more tolerant of noise than others. For example, schools, hospitals,
churches, and residences are more sensitive to noise intrusion than are commercial or industrial
developments and related activities. As ambient noise levels affect the perceived amenity or
livability of a development, so too can the mismanagement of noise impacts impair the economic
health and growth potential of a community by reducing the area’s desirability as a place to live,
shop and work. For this reason, land use compatibility with the noise environment is an
important consideration in the planning and design process. The FHWA encourages State and
Local government to regulate land development in such a way that noise-sensitive land uses are
either prohibited from being located adjacent to a highway, or that the developments are
planned, designed, and constructed in such a way that noise impacts are minimized. (6)
2.7 COMMUNITY RESPONSE TO NOISE
Community responses to noise may range from registering a complaint by telephone or letter, to
initiating court action, depending upon everyone’s susceptibility to noise and personal attitudes
about noise. Several factors are related to the level of community annoyance including:
• Fear associated with noise producing activities;
• Socio-economic status and educational level;
• Perception that those affected are being unfairly treated;
• Attitudes regarding the usefulness of the noise-producing activity;
• Belief that the noise source can be controlled.
Approximately ten percent of the population has a very low tolerance for noise and will object to
any noise not of their making. Consequently, even in the quietest environment, some complaints
will occur. Twenty-five percent of the population will not complain even in very severe noise
environments. Thus, a variety of reactions can be expected from people exposed to any given
noise environment. (7) Surveys have shown that about ten percent of the people exposed to
traffic noise of 60 dBA will report being highly annoyed with the noise, and each increase of one
dBA is associated with approximately two percent more people being highly annoyed. When
traffic noise exceeds 60 dBA or aircraft noise exceeds 55 dBA, people may begin to complain. (7)
Despite this variability in behavior on an individual level, the population can be expected to
exhibit the following responses to changes in noise levels as shown on Exhibit 2-B. A change of

3 dBA are considered barely perceptible, and changes of 5 dBA are considered readily perceptible.

EXHIBIT 2-B: NOISE LEVEL INCREASE PERCEPTION
2.8 VIBRATION
Per the Federal Transit Administration (FTA) Transit Noise and Vibration Impact Assessment
Manual (8), vibration is the periodic oscillation of a medium or object. The rumbling sound
caused by the vibration of room surfaces is called structure-borne noise. Sources of ground-
borne vibrations include natural phenomena (e.g., earthquakes, volcanic eruptions, sea waves,
landslides) or human-made causes (e.g., explosions, machinery, traffic, trains, construction
equipment). Vibration sources may be continuous, such as factory machinery, or transient, such
as explosions. As is the case with airborne sound, ground-borne vibrations may be described by
amplitude and frequency.
There are several different methods that are used to quantify vibration. The peak particle
velocity (PPV) is defined as the maximum instantaneous peak of the vibration signal. The PPV is
most frequently used to describe vibration impacts to buildings but is not always suitable for
evaluating human response (annoyance) because it takes some time for the human body to
respond to vibration signals. Instead, the human body responds to average vibration amplitude
often described as the root mean square (RMS). The RMS amplitude is defined as the average of
the squared amplitude of the signal and is most frequently used to describe the effect of vibration
on the human body. Decibel notation (VdB) is commonly used to measure RMS. Decibel notation
(VdB) serves to reduce the range of numbers used to describe human response to vibration.
Typically, ground-borne vibration generated by man-made activities attenuates rapidly with
distance from the source of the vibration. Sensitive receivers for vibration include structures
(especially older masonry structures), people (especially residents, the elderly, and sick), and
vibration-sensitive equipment and/or activities.
The background vibration-velocity level in residential areas is generally 50 VdB. Ground-borne
vibration is normally perceptible to humans at approximately 65 VdB. For most people, a
vibration-velocity level of 75 VdB is the approximate dividing line between barely perceptible and
distinctly perceptible levels. Typical outdoor sources of perceptible ground-borne vibration are
construction equipment, steel-wheeled trains, and traffic on rough roads. If a roadway is smooth,
the ground-borne vibration is rarely perceptible. The range of interest is from approximately 50

VdB, which is the typical background vibration-velocity level, to 100 VdB, which is the general
threshold where minor damage can occur in fragile buildings. Exhibit 2-C illustrates common
vibration sources and the human and structural response to ground-borne vibration.

3 REGULATORY SETTING
To limit population exposure to physically and/or psychologically damaging as well as intrusive
noise levels, the federal government, the State of California, various county governments, and
most municipalities in the State have established standards and ordinances to control noise. In
most areas, automobile and truck traffic is the major source of environmental noise. Traffic
activity generally produces an average sound level that remains constant with time. Air and rail
traffic, and commercial and industrial activities are also major sources of noise in some areas.
Federal, state, and local agencies regulate different aspects of environmental noise. Federal and
state agencies generally set noise standards for mobile sources such as aircraft and motor
vehicles, while regulation of stationary sources is left to local agencies.
3.1 STATE OF CALIFORNIA NOISE REQUIREMENTS
The State of California regulates freeway noise, sets standards for sound transmission, provides
occupational noise control criteria, identifies noise standards, and provides guidance for local
land use compatibility. State law requires that each county and city adopt a General Plan that
includes a Noise Element which is to be prepared per guidelines adopted by the Governor’s Office
of Planning and Research (OPR). (9) The purpose of the Noise Element is to limit the exposure of
the community to excessive noise levels. In addition, the California Environmental Quality Act
(CEQA) requires that all known environmental effects of a project be analyzed, including
environmental noise impacts.
3.2 STATE OF CALIFORNIA GREEN BUILDING STANDARDS CODE
The State of California’s Green Building Standards Code contains mandatory measures for non-
residential building construction in Section 5.507 on Environmental Comfort. (10) These noise
standards are applied to new construction in California for controlling interior noise levels
resulting from exterior noise sources. The regulations specify that acoustical studies must be
prepared when non-residential structures are developed in areas where the exterior noise levels
exceed 65 dBA CNEL, such as within a noise contour of an airport, freeway, railroad, and other
areas where noise contours are not readily available. If the development falls within an airport
or freeway 65 dBA CNEL noise contour, the combined sound transmission class (STC) rating of
the wall and roof-ceiling assemblies must be at least 50. For those developments in areas where
noise contours are not readily available and the noise level exceeds 65 dBA Leq for any hour of
operation, a wall and roof-ceiling combined STC rating of 45, and exterior windows with a
minimum STC rating of 40 are required (Section 5.507.4.1).
3.3 CITY OF FONTANA GENERAL PLAN NOISE ELEMENT
The City of Fontana General Plan was updated on November 13, 2018. (11) To protect residents
from the negative effect of “spillover” noise (Goal #10), the City of Fontana has identified the
following policies in the General Plan Noise Element:
Slover Avenue and Cypress Avenue Warehouse Noise Impact Analysis
13921-06 Noise Study
14
Policy
Residential land uses and areas identified as noise-sensitive shall be protected from excessive noise from
non-transportation sources including industrial, commercial, and residential activities and equipment.
Actions
A. Projects located in commercial areas shall not exceed stationary- source noise standards
at the property line of proximate residential or commercial uses.
B. Industrial uses shall not exceed commercial or residential stationary source noise
standards at the most proximate land uses.
C. Non-transportation noise shall be considered in land use planning decisions.
D. Construction shall be performed as quietly as feasible when performed in proximity to
residential or other noise sensitive land uses.
3.4 OPERATIONAL NOISE STANDARDS
To analyze noise impacts originating from a designated fixed location or private property such as
the Slover Avenue and Cypress Avenue Warehouse Project, stationary-source (operational) noise
such as the expected loading dock activity, roof-top air conditioning units, parking lot vehicle
movements, trash enclosure activity, and truck movements are typically evaluated against
standards established under a jurisdiction’s Municipal Code.
The City of Fontana noise control guidelines for determining and mitigating non-transportation
or stationary noise source impacts from operations in neighboring residential areas are found in
the Zoning and Development Code (Section 30-543), provided in Appendix 3.1. For industrial
zoning districts, Section 30-543 indicates that no person shall create or cause to be created any
sound which exceeds the noise levels in this section as measured at the property line of any
residentially zoned property. The performance standards found in Section 30-543 limit the
exterior noise level to 70 dBA Leq during the daytime hours, and 65 dBA Leq during the nighttime
hours at sensitive receiver locations as shown on Table 3-1. (12)

3.5 CONSTRUCTION NOISE STANDARDS
The City of Fontana has set restrictions to control noise impacts associated with the construction
of the proposed Project. According to Section 18-63(b)(7), Construction or repairing of buildings
or structures, construction activity is limited: between the hours of 7:00 a.m. and 6:00 p.m. on
weekdays and between the hours of 8:00 a.m. and 5:00 p.m. on Saturdays except in the case of
urgent necessity. (13) Project construction noise levels are, therefore, considered exempt from

13921-06 Noise Study
15
municipal regulation if activities occur within the hours specified in the City of Fontana Municipal
Code, Section 18-63(7) of 7:00 a.m. to 6:00 p.m. on weekdays and between the hours of 8:00
a.m. to 5:00 p.m. on Saturdays. However, if activity occurs outside of these hours, the City of
Fontana stationary-source (operational) noise level standards of 70 dBA Leq during the daytime
hours, and 65 dBA Leq during the nighttime hours shall apply as previously discussed in Section
3.4.
3.6 CONSTRUCTION VIBRATION STANDARDS
To analyze vibration impacts originating from the operation and construction of the Slover
Avenue and Cypress Avenue Warehouse, vibration-generating activities are typically evaluated
against standards established under a City’s Municipal Code. The City of Fontana Municipal Code,
Section 30-543, indicates that operational vibration levels shall not create or cause to be created
any activity that causes a vibration that can be felt beyond the property line with or without the
aid of an instrument. (13) For analysis purposes, a peak-particle-velocity (PPV) vibration
threshold of 0.2 in/sec PPV is used to determine perception consistent with the City of Fontana
Municipal Code requirements based on guidance provided by the Federal Transit Administration,
Transit Noise and Vibration Impact Assessment Manual. (8)
3.7 AIRPORT LAND USE COMPATIBILITY
The Project site is located roughly 7.7 miles northeast of the Ontario International Airport (ONT).
This places the Project site within the ONT Airport Influence Area according to Policy Map 2-1 of
the Ontario International Airport Land Use Compatibility Plan (ONT ALUCP). The ONT ALUCP was
amended July 2018 to promote compatibility between airport and the land uses that surround it.
(14) Since the Project site is located within the ONT Airport Influence Area, the Project is subject
to the Noise Criteria established on Table 2-3 in the ONT ALUCP. As shown on Exhibit 3-B, the
Project site is located within the ONT Airport Influence Area but outside the 60 dBA CNEL airport
noise impact zone consistent with Policy Map 2-3.
According to Table 2-3 of the ONT ALUCP, industrial land uses located outside the 60 dBA CNEL
noise level contours of ONT, such as the Project, are considered normally compatible land use
and must reduce interior noise levels to 50 dBA CNEL. Standard building construction practices
required under the State of California Green Building Standards Code (CALGreen) typically
provide up to 25 dBA CNEL of attenuation. With respect to noise generated by the ONT Airport
facilities and activities, application of standard CALGreen construction practices would yield
acceptable Project interior noise levels of approximately 35 dBA CNEL. In addition, the Project
does not propose or require facilities or actions that would contribute to or exacerbate noise
generated by ONT facilities and activities. Therefore, the Project would not be adversely affected
by airport/airfield noise, nor would the Project contribute to or result in adverse airport/airfield
noise impacts.

4 SIGNIFICANCE CRITERIA
The following significance criteria are based on currently adopted guidance provided by Appendix
G of the California Environmental Quality Act (CEQA) Guidelines. (1) For the purposes of this
report, impacts would be potentially significant if the Project results in or causes:
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 ground-borne vibration or ground-borne 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 project area to excessive noise levels?
While the City of Fontana General Plan Guidelines provide direction on noise compatibility and
establish noise standards by land use type that are sufficient to assess the significance of noise
impacts, they do not define the levels at which increases are considered substantial for use under
Guideline A. CEQA Appendix G Guideline C applies to nearby public and private airports, if any,
and the Project’s land use compatibility.
4.1 CEQA GUIDELINES NOT FURTHER ANALYZED
As previously indicated in Section 3.7, the ONT Airport noise contour boundaries are presented
on Exhibit 3-B of this report and show that the Project is considered normally compatible land
use since it is located outside the 60 dBA CNEL noise impact zone. Industrial/business
park/commercial land uses located outside the 60 dBA CNEL noise level contours of ONT, such as
the Project evaluated here, are considered a normally compatible land use, and must reduce
interior noise levels to 50 dBA CNEL. Standard building construction practices required under the
State of California Green Building Standards Code (CALGreen) typically provide up to 25 dBA CNEL
of attenuation. As such, application of standard CALGreen construction practices would yield
acceptable Project interior noise levels of approximately 35 dBA CNEL. Potential airstrip/airport
noise impacts affecting the Project are therefore not further analyzed.
4.2 NOISE-SENSITIVE RECEIVERS
Noise level increases resulting from the Project are evaluated based on the Appendix G CEQA
Guidelines described above at the closest sensitive receiver locations. Under CEQA,
consideration must be given to the magnitude of the increase, the existing ambient noise levels,
and the location of noise-sensitive receivers to determine if a noise increase represents a
significant adverse environmental impact. This approach recognizes that there is no single noise
increase that renders the noise impact significant. (15)
Unfortunately, there is no completely satisfactory way to measure the subjective effects of noise
or of the corresponding human reactions of annoyance and dissatisfaction. This is primarily
because of the wide variation in individual thresholds of annoyance and differing individual
Slover Avenue and Cypress Avenue Warehouse Noise Impact Analysis
13921-06 Noise Study
18
experiences with noise. Thus, an important way of determining a person’s subjective reaction to
a new noise is the comparison of it to the existing environment to which one has adapted—the
so-called ambient environment. In general, the more a new noise exceeds the previously existing
ambient noise level, the less acceptable the new noise will typically be judged. The Federal
Interagency Committee on Noise (FICON) (16) developed guidance to be used for the assessment
of project-generated increases in noise levels that consider the ambient noise level. The FICON
recommendations are based on studies that relate aircraft noise levels to the percentage of
persons highly annoyed by aircraft noise. Although the FICON recommendations were
specifically developed to assess aircraft noise impacts, these recommendations are often used in
environmental noise impact assessments involving the use of cumulative noise exposure metrics,
such as the average-daily noise level (CNEL) and equivalent continuous noise level (Leq).
As previously stated, the approach used in this noise study recognizes that there is no single noise
increase that renders the noise impact significant, based on a 2008 California Court of Appeal
ruling on Gray v. County of Madera. (15) For example, if the ambient noise environment is quiet
(<60 dBA) and the new noise source greatly increases the noise levels, an impact may occur if the
noise criteria may be exceeded. Therefore, for this analysis, FICON identifies a readily perceptible
5 dBA or greater project-related noise level increase is considered a significant impact when the
noise criteria for a given land use is exceeded. Per the FICON, in areas where the without project
noise levels range from 60 to 65 dBA, a 3 dBA barely perceptible noise level increase appears to
be appropriate for most people. When the without project noise levels already exceed 65 dBA,
any increase in community noise louder than 1.5 dBA or greater is considered a significant impact
if the noise criteria for a given land use is exceeded, since it likely contributes to an existing noise
exposure exceedance.
The FICON guidance provides an established source of criteria to assess the impacts of substantial
temporary or permanent increase in ambient noise levels. Based on the FICON criteria, the
amount to which a given noise level increase is considered acceptable is reduced when the
without Project noise levels are already shown to exceed certain land-use specific exterior noise
level criteria. The specific levels are based on typical responses to noise level increases of 5 dBA
or readily perceptible, 3 dBA or barely perceptible, and 1.5 dBA depending on the underlying
without Project noise levels for noise-sensitive uses. These levels of increases and their perceived
acceptance are consistent with guidance provided by both the Federal Highway Administration
(5 p. 9) and Caltrans (17 p. 2_48).

5 EXISTING NOISE LEVEL MEASUREMENTS
To assess the existing noise level environment, 24-hour noise level measurements were taken at
four locations in the Project study area. The receiver locations were selected to describe and
document the existing noise environment within the Project study area. Exhibit 5-A provides the
boundaries of the Project study area and the noise level measurement locations. To fully
describe the existing noise conditions, noise level measurements were collected by Urban
Crossroads, Inc. on Wednesday, August 5th, 2020. Appendix 5.1 includes study area photos.
5.1 MEASUREMENT PROCEDURE AND CRITERIA
To describe the existing noise environment, the hourly noise levels were measured during typical
weekday conditions over a 24-hour period. By collecting individual hourly noise level
measurements, it is possible to describe the daytime and nighttime hourly noise levels and
calculate the 24-hour CNEL. The long-term noise readings were recorded using Piccolo Type 2
integrating sound level meter and dataloggers. The Piccolo sound level meters were calibrated
using a Larson-Davis calibrator, Model CAL 150. All noise meters were programmed in "slow"
mode to record noise levels in "A" weighted form. The sound level meters and microphones
were equipped with a windscreen during all measurements. All noise level measurement
equipment satisfies the American National Standards Institute (ANSI) standard specifications for
sound level meters ANSI S1.4-2014/IEC 61672-1:2013. (18)
5.2 NOISE MEASUREMENT LOCATIONS
The long-term noise level measurements were positioned as close to the nearest sensitive
receiver locations as possible to assess the existing ambient hourly noise levels surrounding the
Project site. Both Caltrans and the FTA recognize that it is not reasonable to collect noise level
measurements that can fully represent every part of a private yard, patio, deck, or balcony
normally used for human activity when estimating impacts for new development projects. This
is demonstrated in the Caltrans general site location guidelines which indicate that, sites must be
free of noise contamination by sources other than sources of interest. Avoid sites located near
sources such as barking dogs, lawnmowers, pool pumps, and air conditioners unless it is the
express intent of the analyst to measure these sources. (3) Further, FTA guidance states, that it is
not necessary nor recommended that existing noise exposure be determined by measuring at
every noise-sensitive location in the project area. Rather, the recommended approach is to
characterize the noise environment for clusters of sites based on measurements or estimates at
representative locations in the community. (8)
Based on recommendations of Caltrans and the FTA, it is not necessary to collect measurements
at each individual building or residence, because each receiver measurement represents a group
of buildings that share acoustical equivalence. (8) In other words, the area represented by the
receiver shares similar shielding, terrain, and geometric relationship to the reference noise
source. Receivers represent a location of noise sensitive areas and are used to estimate the
future noise level impacts. Collecting reference ambient noise level measurements at the nearby
sensitive receiver locations allows for a comparison of the before and after Project noise levels
Slover Avenue and Cypress Avenue Warehouse Noise Impact Analysis
13921-06 Noise Study
22
and is necessary to assess potential noise impacts due to the Project’s contribution to the
ambient noise levels.
5.3 NOISE MEASUREMENT RESULTS
The noise measurements presented below focus on the average or equivalent sound levels (Leq).
The equivalent sound level (Leq) represents a steady state sound level containing the same total
energy as a time varying signal over a given sample period. Table 5-1 identifies the hourly
daytime (7:00 a.m. to 10:00 p.m.) and nighttime (10:00 p.m. to 7:00 a.m.) noise levels at each
noise level measurement location.

6 TRAFFIC NOISE METHODS AND PROCEDURES
The following section outlines the methods and procedures used to model and analyze the future
traffic noise environment. Consistent with the Land Use Compatibility Criteria, all transportation
related noise levels are presented in terms of the 24-hour CNEL’s.
6.1 FHWA TRAFFIC NOISE PREDICTION MODEL
The expected roadway noise level increases from vehicular traffic were calculated by Urban
Crossroads, Inc. using a computer program that replicates the Federal Highway Administration
(FHWA) Traffic Noise Prediction Model- FHWA-RD-77-108. (19) The FHWA Model arrives at a
predicted noise level through a series of adjustments to the Reference Energy Mean Emission
Level (REMEL). In California the national REMELs are substituted with the California Vehicle Noise
(Calveno) Emission Levels. (20) Adjustments are then made to the REMEL to account for: the
roadway classification (e.g., collector, secondary, major or arterial), the roadway active width
(i.e., the distance between the center of the outermost travel lanes on each side of the roadway),
the total average daily traffic (ADT), the travel speed, the percentages of automobiles, medium
trucks, and heavy trucks in the traffic volume, the roadway grade, the angle of view (e.g., whether
the roadway view is blocked), the site conditions ("hard" or "soft" relates to the absorption of
the ground, pavement, or landscaping), and the percentage of total ADT which flows each hour
throughout a 24-hour period. Research conducted by Caltrans has shown that the use of soft site
conditions is appropriate for the application of the FHWA traffic noise prediction model used in
this analysis. (21)
6.2 OFF-SITE TRAFFIC NOISE PREDICTION MODEL INPUTS
Table 6-1 presents the roadway parameters used to assess the Project’s off-site dBA CNEL
transportation noise impacts consistent with the Slover Avenue and Cypress Avenue Warehouse
Traffic Study, prepared by Urban Crossroads, Inc. Table 6-1 identifies the three study area
roadway segments, the distance from the centerline to adjacent land use based on the functional
roadway classifications per the City of Fontana General Plan Circulation Element, and the posted
vehicle speeds. The ADT volumes used in this study area presented on Table 6-2 are based on
the Slover Avenue and Cypress Avenue Warehouse Traffic Study, prepared by Urban Crossroads,
Inc. for the following traffic scenarios under both Without and With Project alternatives: Existing
(2021), and Opening Year Cumulative (OYC) (2023). (2)
The ADT volumes vary for each roadway segment based on the existing traffic volumes and the
combination of project traffic distributions. This analysis relies on a comparative evaluation of
the off-site traffic noise impacts, without and with project ADT traffic volumes from the Project
traffic study.

To quantify the off-site noise levels, the Project related truck trips were added to the heavy truck
category in the FHWA noise prediction model. The addition of the Project related truck trips
increases the percentage of heavy trucks in the vehicle mix. This approach recognizes that the
FHWA noise prediction model is significantly influenced by the number of heavy trucks in the
vehicle mix. Table 6-3 provides the time of day (daytime, evening, and nighttime) vehicle splits.
The daily Project truck trip-ends were assigned to the individual off-site study area roadway
segments based on the Project truck trip distribution percentages documented in the Traffic
Impact Analysis. Using the Project truck trips in combination with the Project trip distribution,
Urban Crossroads, Inc. calculated the number of additional Project truck trips and vehicle mix
percentages for each of the study area roadway segments. Table 6-4 shows the traffic flow by
vehicle type (vehicle mix) used for all without Project traffic scenarios, and Tables 6-5 and 6-6
show the vehicle mixes used for the with Project traffic scenarios.

Due to the added Project truck trips, the increase in Project traffic volumes and the distributions
of trucks on the study area road segments, the percentage of autos, medium trucks and heavy
trucks will vary for each of the traffic scenarios. This explains why the existing and future traffic
volumes and vehicle mixes vary between seemingly identical study area roadway segments.

7 OFF-SITE TRAFFIC NOISE ANALYSIS
To assess the off-site transportation CNEL noise level impacts associated with the proposed
Project, noise contours were developed based on the Slover Avenue and Cypress Avenue
Warehouse Traffic Analysis. (2) Noise contour boundaries represent the equal levels of noise
exposure and are measured in CNEL from the center of the roadway.
7.1 TRAFFIC NOISE CONTOURS
Noise contours were used to assess the Project's incremental 24-hour dBA CNEL traffic-related
noise impacts at land uses adjacent to roadways conveying Project traffic. The noise contours
represent the distance to noise levels of a constant value and are measured from the center of
the roadway for the 70, 65, and 60 dBA CNEL noise levels. The noise contours do not consider
the effect of any existing noise barriers or topography that may attenuate ambient noise levels.
In addition, because the noise contours reflect modeling of vehicular noise on area roadways,
they appropriately do not reflect noise contributions from the surrounding stationary noise
sources within the Project study area.
Tables 7-1 through 7-4 present a summary of the exterior dBA CNEL traffic noise levels without
barrier attenuation. Roadway segments are analyzed from the without Project to the with
Project conditions in each of the following timeframes: Existing (2021), and OYC (2023).
Appendix 7.1 includes a summary of the dBA CNEL traffic noise level contours for each of the
traffic scenarios.

7.2 EXISTING PROJECT TRAFFIC NOISE LEVEL INCREASES
An analysis of existing traffic noise levels plus traffic noise generated by the proposed Project has
been included in this report to fully analyze all the existing traffic scenarios identified in the Slover
Avenue and Cypress Avenue Warehouse Traffic Impact Analysis. This condition is provided solely
for informational purposes and will not occur, since the Project will not be fully developed and
occupied under Existing conditions. Table 7-1 shows the Existing without Project conditions CNEL
noise levels. The Existing without Project exterior noise levels are expected to range from 75.5
to 76.0 dBA CNEL, without accounting for any noise attenuation features such as noise barriers
or topography. Table 7-2 shows the Existing with Project conditions will range from 76.0 to 76.3
dBA CNEL. Table 7-5 shows that the Project off-site traffic noise level impacts will range from 0.2
to 0.5 dBA CNEL. Based on the significance criteria for off-site traffic noise presented in Table 4-
1, land uses adjacent to the study area roadway segments would experience less than significant
noise level increases on receiving land uses due to the Project-related traffic.
7.3 OYC (2023) PROJECT TRAFFIC NOISE LEVEL INCREASES
Table 7-3 presents the OYC (2023) without Project conditions CNEL noise levels. The OYC (2023)
without Project exterior noise levels are expected to range from 76.4 to 76.8 dBA CNEL, without
accounting for any noise attenuation features such as noise barriers or topography. Table 7-4
shows the OYC (2023) with Project conditions will range from 76.8 to 77.0 dBA CNEL. Table 7-6
shows that the Project off-site traffic noise level increases will range from 0.2 to 0.4 dBA CNEL.
Based on the significance criteria for off-site traffic noise presented in Table 4-1, land uses
adjacent to the study area roadway segments would experience less than significant noise level
increases on receiving land uses due to the Project-related traffic.

8 RECEIVER LOCATIONS
To assess the potential for long-term operational and short-term construction noise impacts, the
following sensitive receiver locations, as shown on Exhibit 8-A, were identified as representative
locations for analysis. Sensitive receivers are generally defined as locations where people reside
or where the presence of unwanted sound could otherwise adversely affect the use of the land.
Noise-sensitive land uses are generally considered to include schools, hospitals, single-family
dwellings, mobile home parks, churches, libraries, and recreation areas. Moderately noise-
sensitive land uses typically include multi-family dwellings, hotels, motels, dormitories, out-
patient clinics, cemeteries, golf courses, country clubs, athletic/tennis clubs, and equestrian
clubs. Land uses that are considered relatively insensitive to noise include business, commercial,
and professional developments. Land uses that are typically not affected by noise include:
industrial, manufacturing, utilities, agriculture, undeveloped land, parking lots, warehousing,
liquid and solid waste facilities, salvage yards, and transit terminals.
To describe the potential off-site Project noise levels, four receiver locations in the vicinity of the
Project site were identified. All distances are measured from the Project site boundary to the
outdoor living areas (e.g., private backyards) or at the building façade, whichever is closer to the
Project site. The selection of receiver locations is based on FHWA guidelines and is consistent
with additional guidance provided by Caltrans and the FTA, as previously described in Section 5.2.
Other sensitive land uses in the Project study area that are located at greater distances than
those identified in this noise study will experience lower noise levels than those presented in this
report due to the additional attenuation from distance and the shielding of intervening
structures. Distance is measured in a straight line from the project boundary to each receiver
location.
R1: Location R1 represents the existing noise sensitive residence at 16412 Washington Drive,
approximately 485 feet north of the Project site. Since there are no private outdoor living
areas (backyards) facing the Project site, receiver R1 is placed at the residential building
façade. L1, A 24-hour noise measurement is used to describe the existing ambient noise
environment.
R2: Location R2 represents the existing noise sensitive residence at 16515 Slover Avenue,
approximately 226 feet southeast of the Project site. Receiver R2 is placed at the outdoor
living areas (backyards) facing the Project site. A 24-hour noise measurement was taken
near this location, L3, to describe the existing ambient noise environment.
R3: Location R3 represents the existing noise sensitive residence at 16355 Slover Avenue,
approximately 161 feet south of the Project site. Since there are no private outdoor living
areas (backyards) facing the Project site, receiver R3 is placed at the residential building
façade. A 24-hour noise measurement near this location, L4, is used to describe the
existing ambient noise environment.
R4: Location R4 represents the existing noise sensitive residence at 10424 Oleander Avenue,
approximately 94 feet west of the Project site. Since there are no private outdoor living
areas (backyards) facing the Project site, receiver R4 is placed at the residential building
façade. A 24-hour noise measurement, L1, is used to describe the existing ambient noise
environment.

9 OPERATIONAL NOISE ANALYSIS
This section analyzes the potential stationary-source operational noise impacts at the nearby
receiver locations, identified in Section 8, resulting from the operation of the proposed Slover
Avenue and Cypress Avenue Warehouse Project. Exhibit 9-A identifies the noise source locations
and the planned 14-foot-high screen wall used to assess the operational noise levels.
9.1 OPERATIONAL NOISE SOURCES
This operational noise analysis is intended to describe noise level impacts associated with the
expected typical of daytime and nighttime activities at the Project site. To present the potential
worst-case noise conditions, this analysis assumes the Project would be operational 24 hours per
day, seven days per week. Consistent with similar warehouse and industrial uses, the Project
business operations would primarily be conducted within the enclosed buildings, except for
traffic movement, parking, as well as loading and unloading of trucks at designated loading bays.
The on-site Project-related noise sources are expected to include: loading dock activity, roof-top
air conditioning units, parking lot vehicle movements, trash enclosure activity, and truck
movements.
9.2 REFERENCE NOISE LEVELS
To estimate the Project operational noise impacts, reference noise level measurements were
collected from similar types of activities to represent the noise levels expected with the
development of the proposed Project. This section provides a detailed description of the
reference noise level measurements shown on Table 9-1 used to estimate the Project operational
noise impacts. It is important to note that the following projected noise levels assume the worst-
case noise environment with the loading dock activity, roof-top air conditioning units, parking lot
vehicle movements, trash enclosure activity, and truck movements all operating at the same
time. These sources of noise activity will likely vary throughout the day.
9.2.1 MEASUREMENT PROCEDURES
The reference noise level measurements presented in this section were collected using a Larson
Davis LxT Type 1 precisions sound level meter (serial number 01146). The LxT sound level meter
was calibrated using a Larson-Davis calibrator, Model CAL 200, was programmed in "slow" mode
to record noise levels in "A" weighted form and was located at approximately five feet above the
ground elevation for each measurement. The sound level meters and microphones were
equipped with a windscreen during all measurements. All noise level measurement equipment
satisfies the American National Standards Institute (ANSI) standard specifications for sound level
meters ANSI S1.4-2014/IEC 61672-1:2013. (18)

3 Sound power level represents the total amount of acoustical energy (noise level) produced by a sound source independent
of distance or surroundings. Sound power levels calculated using the CadnaA noise model at the reference distance to the
noise source. Numbers may vary due to size differences between point and area noise sources.
9.2.2 COLD STORAGE LOADING DOCK ACTIVITY
To describe the loading dock activities, a reference noise level measurement was collected to
represent the truck activities. The reference noise level measurement was taken in the center of
the loading dock activity area and represents multiple concurrent noise sources resulting in a
combined noise level of 65.7 dBA Leq at a uniform distance of 50 feet. Specifically, the reference
noise level measurement represents one truck located approximately 30 feet from the noise level
meter with another truck passing by to park roughly 20 feet away, both with their engines idling.
Throughout the reference noise level measurement, a separate docked and running reefer truck
was located approximately 50 feet east of the measurement location. Additional background
noise sources included truck pass-by noise, truck drivers talking to each other next to docked
trucks, and air brake release noise when trucks parked.
9.2.3 ROOF-TOP AIR CONDITIONING UNITS
The noise level measurements describe a single mechanical roof-top air conditioning unit. The
reference noise level represents a Lennox SCA120 series 10-ton model packaged air conditioning
unit. At the uniform reference distance of 50 feet, the reference noise levels are 57.2 dBA Leq.
Based on the typical operating conditions observed over a four-day measurement period, the
roof-top air conditioning units are estimated to operate for and average 39 minutes per hour
during the daytime hours, and 28 minutes per hour during the nighttime hours. These operating
conditions reflect peak summer cooling requirements with measured temperatures approaching
96 degrees Fahrenheit (°F) with average daytime temperatures of 82°F. For this noise analysis,
the air conditioning units are expected to be located on the roof of the Project buildings.
9.2.5 TRASH ENCLOSURE ACTIVITY
To describe the noise levels associated with a trash enclosure activity, Urban Crossroads collected
a reference noise level measurement at an existing trash enclosure containing two dumpster
bins. The trash enclosure noise levels describe metal gates opening and closing, metal scraping
Slover Avenue and Cypress Avenue Warehouse Noise Impact Analysis
13921-06 Noise Study
38
against concrete floor sounds, dumpster movement on metal wheels, and trash dropping into
the metal dumpster. The reference noise levels describe trash enclosure noise activities when
trash is dropped into an empty metal dumpster, as would occur at the Project Site. The measured
reference noise level at the uniform 50-foot reference distance is 57.3 dBA Leq for the trash
enclosure activity. The reference noise level describes the expected noise source activities
associated with the trash enclosures for the Project’s proposed building. Typical trash enclosure
activities are estimated to occur for 10 minutes per hour.
9.2.6 PARKING LOT VEHICLE MOVEMENTS
To describe the on-site parking lot activity a reference noise level of 56.1 dBA Leq at 50 feet is
used. Parking activities are expected to take place during the full hour (60 minutes) throughout
the daytime and evening hours. The parking lot noise levels are mainly due cars pulling in and
out of parking spaces.
9.2.6 TRUCK MOVEMENTS
The truck movements reference noise level measurement was collected over a period of 1 hour
and 28 minutes and represents multiple heavy trucks entering and exiting the outdoor loading
dock area producing a reference noise level of 59.8 dBA Leq at 50 feet. The noise sources included
at this measurement location account for trucks entering and existing the Project driveways and
maneuvering in and out of the outdoor loading dock activity area.
9.3 CADNAA NOISE PREDICTION MODEL
To fully describe the exterior operational noise levels from the Project, Urban Crossroads, Inc.
developed a noise prediction model using the CadnaA (Computer Aided Noise Abatement)
computer program. CadnaA can analyze multiple types of noise sources using the spatially
accurate Project site plan, georeferenced Nearmap aerial imagery, topography, buildings, and
barriers in its calculations to predict outdoor noise levels.
Using the ISO 9613-2 protocol, CadnaA will calculate the distance from each noise source to the
noise receiver locations, using the ground absorption, distance, and barrier/building attenuation
inputs to provide a summary of noise level at each receiver and the partial noise level
contributions by noise source. Consistent with the ISO 9613-2 protocol, the CadnaA noise
prediction model relies on the reference sound power level (Lw) to describe individual noise
sources. While sound pressure levels (e.g., Leq) quantify in decibels the intensity of given sound
sources at a reference distance, sound power levels (Lw) are connected to the sound source and
are independent of distance. Sound pressure levels vary substantially with distance from the
source and diminish because of intervening obstacles and barriers, air absorption, wind, and
other factors. Sound power is the acoustical energy emitted by the sound source and is an
absolute value that is not affected by the environment.
The operational noise level calculations provided in this noise study account for the distance
attenuation provided due to geometric spreading, when sound from a localized stationary source
(i.e., a point source) propagates uniformly outward in a spherical pattern. A default ground
attenuation factor of 0.5 was used in the noise analysis to account for mixed ground representing

39
a combination of hard and soft surfaces. Appendix 9.1 includes the detailed noise model inputs
used to estimate the Project operational noise levels presented in this section including the
planned noise barriers.
9.4 PROJECT OPERATIONAL NOISE LEVELS
Using the reference noise levels to represent the proposed Project operations that include
loading dock activity, roof-top air conditioning units, parking lot vehicle movements, trash
enclosure activity, and truck movements, Urban Crossroads, Inc. calculated the operational
source noise levels that are expected to be generated at the Project site and the Project-related
noise level increases that would be experienced at each of the sensitive receiver locations. The
operational noise level calculations include the planned 14-foot-high screen wall located around
the southern loading dock as shown on Exhibit 9-A. Table 9-2 shows the Project operational noise
levels during the daytime hours of 7:00 a.m. to 10:00 p.m. The daytime hourly noise levels at the
off-site receiver locations are expected to range from 51.1 to 54.2 dBA Leq.

7:00 a.m. The nighttime hourly noise levels at the off-site receiver locations are expected to
range from 51.1 to 54.0 dBA Leq. The differences between the daytime and nighttime noise levels
are largely related to the duration of noise activity and the number of truck movements.

9.5 PROJECT OPERATIONAL NOISE LEVEL COMPLIANCE
To demonstrate compliance with local noise regulations, the Project-only operational noise levels
are evaluated against exterior noise level thresholds based on the City of Fontana exterior noise
level standards at nearby noise-sensitive receiver locations. Table 9-4 shows the operational
noise levels associated with Slover Avenue and Cypress Avenue Warehouse Project will satisfy
the City of Fontana 70 dBA Leq daytime and 65 dBA Leq nighttime exterior noise level standards at
the nearest receiver locations. Therefore, the operational noise impacts are considered less than
significant at the nearby noise-sensitive receiver locations.

"Daytime" = 7:00 a.m. to 10:00 p.m.; "Nighttime" = 10:00 p.m. to 7:00 a.m.
9.6 PROJECT OPERATIONAL NOISE LEVEL INCREASES
To describe the Project operational noise level increases, the Project operational noise levels are
combined with the existing ambient noise levels measurements for the nearby receiver locations
potentially impacted by Project operational noise sources. Since the units used to measure noise,
decibels (dB), are logarithmic units, the Project-operational and existing ambient noise levels
cannot be combined using standard arithmetic equations. (3) Instead, they must be
logarithmically added using the following base equation:
SPLTotal = 10log10[10SPL1/10 + 10SPL2/10 + … 10SPLn/10]
Where “SPL1,” “SPL2,” etc. are equal to the sound pressure levels being combined, or in this case,
the Project-operational and existing ambient noise levels. The difference between the combined
Project and ambient noise levels describes the Project noise level increases to the existing
ambient noise environment. As indicated on Tables 9-5 and 9-6, the Project is not expected to
generate a measurable daytime and nighttime operational noise level increase dBA Leq at the
nearest receiver locations. Project-related operational noise level increases will satisfy the
operational noise level increase significance criteria presented on Table 4-1. Therefore, the
incremental Project operational noise level increase is considered less than significant at all
receiver locations.

10 CONSTRUCTION ANALYSIS
This section analyzes potential impacts resulting from the short-term construction activities
associated with the development of the Project. Exhibit 10-A shows the construction activity
boundaries in relation to the nearest sensitive receiver locations previously described in Section
8. City of Fontana Municipal Code Section 18-63(7), states that project construction noise levels
are considered exempt between 7:00 a.m. and 6:00 p.m. on weekdays and between the hours of
8:00 a.m. to 5:00 p.m. on Saturdays.
If Project construction activity occurs outside of the hours specified in the Municipal Code, noise
levels shall satisfy the City of Fontana construction noise level thresholds of 70 dBA Leq during the
daytime hours and 65 dBA Leq during the nighttime hours.
10.1 CONSTRUCTION NOISE LEVELS
Noise generated by the Project construction equipment will include a combination of trucks,
power tools, concrete mixers, and portable generators that when combined can reach high
levels. The number and mix of construction equipment are expected to occur in the following
stages:
• Demolition
• Site Preparation
• Grading
• Building Construction
• Paving
• Architectural Coating
10.2 CONSTRUCTION REFERENCE NOISE LEVELS
To describe peak construction noise activities, this construction noise analysis was prepared using
reference noise level measurements published in the Update of Noise Database for Prediction of
Noise on Construction and Open Sites by the Department for Environment, Food and Rural Affairs
(DEFRA). (22). The DEFRA database provides the most recent and comprehensive source of
reference construction noise levels. Table 10-1 provides a summary of the DEFRA construction
reference noise level measurements expressed in hourly average dBA Leq using the estimated
FHWA Roadway Construction Noise Model (RCNM) usage factors (23) to describe the typical
construction activities for each stage of Project construction.

Transit Noise and Vibration Impact Assessment guidance for general construction noise assessment.
10.3 CONSTRUCTION NOISE ANALYSIS
Using the reference construction equipment noise levels and the CadnaA noise prediction model,
calculations of the Project construction noise level impacts at the nearest sensitive receiver
locations were completed. To assess the worst-case construction noise levels, the Project
construction noise analysis relies on the highest noise level impacts when multiple pieces of
equipment with the highest reference noise level is operating at the closest point from the edge
of primary construction activity (Project site boundary) to each receiver location. Consistent with
FTA guidance for general construction noise assessment, Table 10-1 presents the combined noise
levels for all equipment, assuming they operate at the same time. As shown on Table 10-2, the
construction noise levels are expected to range from 61.4 to 73.5 dBA Leq, and the highest
construction levels are expected to range from 68.4 to 73.5 dBA Leq at the nearest receiver
locations. Appendix 10.1 includes the detailed CadnaA construction noise model inputs.

10.4 CONSTRUCTION NOISE LEVEL COMPLIANCE
The construction noise analysis shows that the highest construction noise levels will occur when
construction activities take place at the closest point from the edge of primary construction
activity to each of the nearby receiver locations. Project construction noise levels are considered
exempt if activities occur within the hours specified in the City of Fontana Municipal Code,
Section 18-63(7) of 7:00 a.m. to 6:00 p.m. on weekdays and between the hours of 8:00 a.m. to
5:00 p.m. on Saturdays.
If Project construction activity occurs outside of the hours specified in the Municipal Code, noise
levels shall satisfy the City of Fontana construction noise level thresholds of 70 dBA Leq during the
daytime hours and 65 dBA Leq during the nighttime hours. At the time of this analysis, no Project
construction activity is planned within the hours specified in the City of Fontana Municipal Code,
Section 18-63(7). As shown on table 10-3, the noise impacts due to project construction noise is
considered less than significant at all receiver locations.

10.5 NIGHTTIME CONCRETE POUR NOISE ANALYSIS
It is our understanding that nighttime concrete pouring activities will occur as a part of Project
building construction activities. Nighttime concrete pouring activities are often used to support
reduced concrete mixer truck transit times and lower air temperatures than during the daytime
hours and are generally limited to the actual building area as shown on Exhibit 10-B. Since the
nighttime concrete pours will take place outside the permitted City of Fontana Municipal Code,
Section 18-63(b)(7) hours of 7:00 a.m. and 6:00 p.m. on weekdays and between the hours of 8:00
a.m. and 5:00 p.m. on Saturdays the Project Applicant will be required to obtain authorization
for nighttime work from the City of Fontana. Any nighttime construction noise activities shall
satisfy the residential noise limit categories outlined in Table 3-1.
As shown on Table 10-4, the noise levels associated with the nighttime concrete pour activities
(paving) are estimated to range from 51.1 to 54.2 dBA Leq and will satisfy the City of Fontana 65
dBA Leq nighttime stationary-source exterior hourly average Leq residential noise level threshold
at all the receiver locations. Based on the results of this analysis, all nearest noise receiver
locations will experience less than significant impacts due to the Project related nighttime
concrete pour activities. Appendix 10.2 includes the CadnaA nighttime concrete pour noise
model inputs.

10.6 TYPICAL CONSTRUCTION VIBRATION ANALYSIS
Construction activity can result in varying degrees of ground vibration, depending on the
equipment and methods used, distance to the affected structures and soil type. It is expected
that ground-borne vibration from Project construction activities would cause only intermittent,
localized intrusion. Ground-borne vibration levels resulting from typical construction activities
occurring within the Development Site were estimated by data published by the Federal Transit
Administration (FTA). (8) However, while vehicular traffic is rarely perceptible, construction has
the potential to result in varying degrees of temporary ground vibration, depending on the
specific construction activities and equipment used. Ground vibration levels associated with
various types of construction equipment are summarized on Table 10-5. Based on the
representative vibration levels presented for various construction equipment types, it is possible
to estimate the potential Project construction vibration levels using the following vibration
assessment methods defined by the FTA. To describe the human response (annoyance)
associated with vibration impacts the FTA provides the following equation: PPVequip = PPVref x
(25/D)1.5

Federal Transit Administration, Transit Noise and Vibration Impact Assessment Manual, September
2018.
Construction activity can result in varying degrees of ground vibration, depending on the
equipment and methods used, distance to the affected structures and soil type. It is expected
that ground-borne vibration from Project construction activities would cause only intermittent,
localized intrusion. The proposed Project’s construction activities most likely to cause vibration
impacts are:
• Heavy Construction Equipment: Although all heavy mobile construction equipment has the
potential of causing at least some perceptible vibration, the vibration is usually short-term and is
not of sufficient magnitude to cause building damage.
• Trucks: Trucks hauling building materials to construction sites can be sources of vibration
intrusion if the haul routes pass through residential neighborhoods on streets with bumps or
potholes. Repairing the bumps and potholes generally eliminates the problem.
Ground-borne vibration levels resulting from construction activities occurring within the Project
site were estimated by data published by the Federal Transit Administration (FTA). Construction
activities that would have the potential to generate low levels of ground-borne vibration within
the Project site include grading. Using the vibration source level of construction equipment
Slover Avenue and Cypress Avenue Warehouse Noise Impact Analysis
13921-06 Noise Study
50
provided on Table 10-5 and the construction vibration assessment methodology published by the
FTA, it is possible to estimate the Project vibration impacts.
At distances ranging from 94 to 495 feet from Project construction activity, construction vibration
velocity levels are estimated to range from 0.001 to 0.012 in/sec PPV, as shown on Table 10-6.
Based on the vibration standards used in this report, the Project construction vibration levels will
satisfy the 0.2 in/sec PPV threshold at all the nearby sensitive receiver locations. Therefore, the
vibration impacts due to Project construction are considered less than significant. Further,
vibration levels at the site of the closest sensitive receiver are unlikely to be sustained during the
entire construction period but will occur rather only during the times that heavy construction
equipment is operating adjacent to the Project site perimeter.
