EXECUTIVE SUMMARY
Urban Crossroads, Inc. has prepared this noise study to determine the noise exposure and the
necessary noise mitigation measures, if any, for the proposed Fontana Corporate Center
development (“Project”) located in the City of Fontana. The Project is to amend the existing
Fontana Gateway Specific Plan to develop 2 warehouses totaling 355,370 square feet. This study
has been prepared consistent with applicable City of Fontana noise standards, and significance
criteria based on guidance provided by Appendix G of the California Environmental Quality Act
(CEQA) Guidelines. (1)
The results of this Fontana Corporate Center Noise Impact Analysis are summarized below based
on the significance criteria in Section 4 of this report. Table ES-1 shows the findings of significance
for each potential noise and/or vibration impact under CEQA before and after any required

1 INTRODUCTION
This noise analysis has been completed to determine the noise impacts associated with the
development of the proposed Fontana Corporate Center (“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 north of Slover Avenue and west of Business Drive in the City of
Fontana, as shown on Exhibit 1-A. The Project site is located south of Interstate 10 the Southern
Pacific Railroad, and approximately four miles east of the Ontario International Airport (ONT).
The closest existing noise-sensitive residential uses in the Project study area are located to the
east and southeast of the Project site, with industrial uses located east, south, and west of the
Project site.
1.2 PROJECT DESCRIPTION
The Project is to amend the existing Fontana Gateway Specific Plan to develop two warehouse
buildings totaling 355,370 square feet. Building 1 to the east is to consist of 212,677 square feet
of warehouse use and Building 2 to the west is to consist of 142,693 square feet of warehousing
use. The Project is anticipated to be developed within a single phase with an Opening Year of
2023. The preliminary site plan for the proposed Project is shown on Exhibit 1-B.
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, trash
enclosure activity, parking lot vehicle movements, and truck movements. This noise analysis is
intended to describe noise level impacts associated with the expected typical 24-hour, seven days
per week operational activities at the Project site
Per the Fontana Corporate Center Traffic Study prepared by Urban Crossroads, Inc., the Project
is expected to generate a total of approximately 622 vehicular trips-ends per day (actual vehicles)
which includes 170 two-way 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
Fontana Corporate Center Noise Impact Analysis
14102-04 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
Fontana Corporate Center Noise Impact Analysis
14102-04 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
Fontana Corporate Center Noise Impact Analysis
14102-04 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
Fontana Corporate Center Noise Impact Analysis

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

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
noise source. If the development falls within an airport or freeway 65 dBA CNEL noise contour,
buildings shall be construction to provide an interior noise level environment attributable to
exterior sources that does not exceed an hourly equivalent level of 50 dBA Leq in occupied areas
during any hour of operation.
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:
Fontana Corporate Center Noise Impact Analysis
14102-04 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 Fontana Corporate Center Project, stationary-source (operational) noise such as the expected
loading dock activity, roof-top air conditioning units, trash enclosure activity, parking lot vehicle
movements, 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)

2 Leq represents a steady state sound level containing the same total energy as a time varying signal over a sample period. "Daytime" = 7:00 a.m. to 10:00 p.m.; "Nighttime" = 10:00 p.m. to 7:00 a.m.
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
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
Fontana Corporate Center Noise Impact Analysis
14102-04 Noise Study 15
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
Construction activity can result in varying degrees of ground-borne vibration, depending on the
equipment and methods used, distance to the affected structures and soil type. Construction
vibration is generally associated with pile driving and rock blasting. Other construction
equipment such as air compressors, light trucks, hydraulic loaders, etc., generates little or no
ground vibration. (8) To analyze vibration impacts originating from the operation and
construction of the Fontana Corporate Center, vibration-generating activities are appropriately
evaluated against standards established under a City’s Municipal Code, if such standards exist.
However, the City of Fontana does not identify specific vibration level limits. Therefore, for
analysis purposes, the Caltrans Transportation and Construction Vibration Guidance Manual,
Table 19, vibration damage are used in this noise study to assess potential temporary
construction-related impacts at adjacent building locations. (14 p. 38) The existing buildings
adjacent to the Project site can best be described as “older residential structures” with a
maximum acceptable continuous vibration threshold of 0.3 PPV (in/sec).
3.7 AIRPORT LAND USE COMPATIBILITY
The Project site is located approximately four miles east 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. (15) 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. For normally compatible
land use, either the activities associated with the land use are inherently noisy or standard
construction methods will sufficiently attenuate exterior noise to an acceptable indoor
community noise equivalent level (CNEL).

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
Threshold C, above, does not require further analysis. 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.
4.2 SIGNIFICANCE CRITERIA SUMMARY
Consistent with guidance provided by the City of Fontana, the following thresholds are used in
this analysis to evaluate potential impacts. (16) Noise impacts, therefore, shall be considered
significant if any of the following occur as a direct result of the proposed development. Table 4-
1 shows the significance criteria summary matrix.
4.3 NON-NOISE-SENSITIVE RECEIVERS
The Office of Planning and Research General Plan Guidelines, Appendix C was used to establish
the satisfactory noise levels of significance for non-noise-sensitive land uses in the Project study
area. (9) To determine if Project-related traffic noise level increases are significant at off-site
non-noise-sensitive land uses, when the noise levels, without or with the Project, at existing and
future non-noise-sensitive land uses (e.g., industrial, etc.) exceed the OPR General Plan
Guidelines, Appendix C: Noise Element Guidelines, normally acceptable 70 dBA CNEL noise level
criteria and the Project creates a barely perceptible 3 dBA CNEL or greater Project-related noise
level increase, noise impacts shall be considered significant.

5 EXISTING NOISE LEVEL MEASUREMENTS
To assess the existing noise level environment, 24-hour noise level measurements were taken at
three 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 Thursday, June 24, 2021. 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. (17)
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
Fontana Corporate Center Noise Impact Analysis
14102-04 Noise Study 20
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. Appendix 5.2 provides a summary of the existing hourly
ambient noise levels.

Table 5-1 provides the (energy average) noise levels used to describe the daytime and nighttime
ambient conditions. These daytime and nighttime energy average noise levels represent the
average of all hourly noise levels observed during these time periods expressed as a single
number. Appendix 5.2 provides summary worksheets of the noise levels for each hour as well as
the minimum, maximum, L1, L2, L5, L8, L25, L50, L90, L95, and L99 percentile noise levels observed
during the daytime and nighttime periods.
The background ambient noise levels in the Project study area are dominated by the
transportation-related noise associated with surface streets. This includes the auto and heavy
truck activities on study area roadway segments near the noise level measurement locations.

6 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. (18) 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. (19) 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. (20)
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. Table 6-1 identifies the five 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 Fontana Corporate
Center 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).
(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.

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 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 through 6-7 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 TRANSPORTATION NOISE IMPACTS
To assess the off-site transportation CNEL noise level impacts associated with the proposed
Project, noise contours were developed based on the Fontana Corporate Center Traffic Study. (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 Opening Year
Cumulative (2023). Appendix 7.1 includes a summary of the dBA CNEL traffic noise level contours
for each of the traffic scenarios.

7.2 EXISTING 2021 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
Fontana Corporate Center Traffic Study prepared by Urban Crossroads, Inc. 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. Therefore, no mitigation measures are
considered to reduce the Existing Plus Project traffic noise level increases. The future OYC traffic
noise conditions that include all cumulative projects are used to determine the significance of
the Project off-site traffic noise level increases on the study area roadway segments. Table 7-1
shows the Existing without Project conditions CNEL noise levels. The Existing without Project
exterior noise levels are expected to range from 71.7 to 75.1 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 71.7 to 75.1 dBA CNEL. Table 7-5 shows that the Project
off-site traffic noise level impacts will range from 0.0 to 0.1 dBA CNEL.
7.3 OYC 2023 PROJECT TRAFFIC NOISE LEVEL INCREASES
Table 7-3 presents the OYC without Project conditions CNEL noise levels. The OYC without
Project exterior noise levels are expected to range from 71.8 to 76.3 dBA CNEL, without
accounting for any noise attenuation features such as noise barriers or topography. Table 7-4
shows the OYC with Project conditions will range from 71.8 to 76.3 dBA CNEL. Table 7-6 shows
that the Project off-site traffic noise level increases will range from 0.0 to 0.1 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, three 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 existing noise sensitive residence at 10463 Calabash Avenue,
approximately 2,198 feet east of the Project site. Since there are no private outdoor living
areas (backyards) facing the Project site, receiver R1 is placed at the building façade. A
24-hour noise measurement was taken near this location, L1, to describe the existing
ambient noise environment.
R2: Location R2 represents the existing noise sensitive residence at 10709 Calabash Avenue,
approximately 2,602 feet east of the Project site. Since there are no private outdoor living
areas (backyards) facing the Project site, receiver R2 is placed at the building façade. A
24-hour noise measurement was taken near this location, L2, to describe the existing
ambient noise environment.
R3: Location R3 represents the existing noise sensitive residence at 13851 Santa Ana Avenue,
approximately 3,626 feet southeast of the Project site. Since there are no private outdoor
living areas (backyards) facing the Project site, receiver R3 is placed at the building façade.
A 24-hour noise measurement was taken near this location, L3, 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 Fontana
Corporate Center Project. Exhibit 9-A identifies the noise source locations 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 light 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, trash enclosure activity, parking lot vehicle movements, 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, trash
enclosure activity, parking lot vehicle movements, and truck movements all operating
continuously. 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 Larson
Davis Lxt Type 1 integrating sound level meters and dataloggers. All sound level meters were
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. (17)

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.
4 Entry Gate & Truck Movements are calculate based on the number of events by time of day (See Table 7-2).
9.2.2 LOADING DOCK ACTIVITY
The reference loading dock activities are intended to describe the typical operational noise
source levels associated with the Project. This includes truck idling, deliveries, backup alarms,
unloading/loading, docking including a combination of tractor trailer semi-trucks, two-axle
delivery trucks, and background forklift operations. At a uniform reference distance of 50 feet,
Urban Crossroads collected a reference noise level of 65.7 dBA Leq. The loading dock activity
noise level measurement was taken over a fifteen-minute period and represents multiple noise
sources taken from the center of activity. The reference noise level measurement includes
employees unloading a docked truck container included the squeaking of the truck’s shocks when
weight was removed from the truck, employees playing music over a radio, as well as a forklift
horn and backup alarm. In addition, during the noise level measurement a truck entered the
loading dock area and proceeded to reverse and dock in a nearby loading bay, adding truck
engine, idling, air brakes noise, in addition to on-going idling of an already docked truck.
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 unit is 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 unit is expected to be located on the roof of the Project building.

14102-04 Noise Study 36
9.2.4 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
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.
9.2.5 PARKING LOT
To describe the on-site parking lot activity, a long-term 29-hour reference noise level
measurement was collected in the center of activity within the staff parking lot of an Amazon
distribution center. At 50 feet from the center of activity, the parking lot produced a reference
noise level of 56.1 dBA Leq. 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 in combination with car doors opening and closing.
9.2.6 TRUCK MOVEMENTS
The truck movements reference noise level measurement was collected over a period of 1 hour
and 28 minutes at the entry gate of the fleet maintenance building at 1333 Virginia Avenue. The
measurements represent 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. This activity is considered a
moving point source or line source and is used to represent the truck movements from the
driveway locations to the loading docks. Since these noise levels represent the typical tractor
trailer entering and exiting, the noise levels adequately describe the planned entry gate and truck
movements activities at the Project Site.
Consistent with the Fontana Corporate Center Traffic Study, the Project is expected to generate
a total of approximately 622 vehicle trip-ends per day (actual vehicles), which includes 170 truck
trip-ends per day. (2) Using the estimated number of truck trips in combination with time-of-day
vehicle splits, the number of truck movements by driveway location were calculated. As shown
on Table 9-2, this information is then used to calculate the truck movements noise source activity
based on the number of events by time of day.

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 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 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 from 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 0.0 was used in the CadnaA noise analysis to account for hard site
conditions. Appendix 9.1 includes the detailed noise model inputs.
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, trash enclosure activity, parking lot vehicle
movements, 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. Table 9-3
shows the Project operational noise levels during the daytime hours of 7:00 a.m. to 10:00 p.m.
Fontana Corporate Center Noise Impact Analysis
14102-04 Noise Study 38
The daytime hourly noise levels at the off-site receiver locations are expected to range from 45.2
to 46.8 dBA Leq.

7:00 a.m. The nighttime hourly noise levels at the off-site receiver locations are expected to
range from 45.2 to 46.8 dBA Leq. The differences between the daytime and nighttime noise levels
are largely related to the duration of noise activity (Table 9-1).

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 9-5 shows the operational
noise levels associated with Fontana Corporate Center Project will satisfy the City of Fontana 70
dBA Leq daytime and 65 dBA Leq nighttime exterior noise level standards at all nearby receiver
locations. Therefore, the operational noise impacts are considered less than significant at the
nearby noise-sensitive receiver locations.

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. Noise levels that would be experienced at receiver locations when
Project-source noise is added to the daytime and nighttime ambient conditions are presented on
Tables 9-6 and 9-7, respectively. As indicated on Tables 9-6 and 9-7, the Project will generate a
daytime and nighttime operational noise level increases ranging from 0.1 to 0.1 dBA Leq at the
nearby receiver locations. Project-related operational noise level increases will satisfy the
operational noise level increase significance criteria presented in Table 4-1, the increases at the
sensitive receiver locations will be less than significant.

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 nearby 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/Crushing
• 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). (21). 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 (22) to describe the typical
construction activities for each stage of Project construction.

10.3 TYPICAL 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 the 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. As shown on Table 10-2,
the construction noise levels are expected to range from 46.7 to 66.2 dBA Leq at the nearest
receiver locations. Appendix 10.1 includes the detailed CadnaA construction noise model inputs.

10.4 TYPICAL 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 46.2 to 49.9 dBA Leq and will satisfy the City of Fontana 65
dBA Leq nighttime stationary-source exterior hourly average Leq residential noise level threshold
at the nearest noise sensitive residential 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 employed. Operation of construction equipment causes ground
vibrations that spread through the ground and diminish in strength with distance. 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 for building damage using the following
vibration assessment methods defined by the FTA. To describe the vibration impacts the FTA
provides the following equation: PPVequip = PPVref x (25/D)1.5

Equipment PPV (in/sec)
at 25 feet
Small bulldozer 0.003
Jackhammer 0.035
Loaded Trucks 0.076
Large bulldozer 0.089
Source: Federal Transit Administration, Transit Noise and Vibration Impact Assessment Manual
Table 10-6 presents the expected Project related vibration levels at the nearest receiver
locations. At distances ranging from 2,198 to 3,626 feet from Project construction activities,
construction vibration velocity levels are estimated at 0.000 PPV (in/sec). Based on maximum
acceptable continuous vibration threshold of 0.3 PPV (in/sec) for older residential buildings, the
typical Project construction vibration levels will satisfy the building damage thresholds at all
receiver locations. In addition, the typical construction vibration levels at the nearest sensitive
receiver locations 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 boundaries.
