1 INTRODUCTION
This noise analysis has been completed to determine the noise impacts associated with the
development of the proposed North Fontana Industrial Complex (Acacia) (“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 east of Sierra Avenue and south of Duncan Canyon Road in the
City of Fontana as shown on Exhibit 1-A.
1.2 PROJECT DESCRIPTION
The proposed Project includes the development of two buildings: a 296,297 square foot
warehouse building (Building 1), and a smaller 88,746 square foot warehouse building (Building
2). It is anticipated to have an Opening Year of 2024. The preliminary site plan for the proposed
Project is shown on Exhibit 1-B.
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 operational activities at the Project site.

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.
(2) 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

at approximately 1,000 feet, which can cause serious discomfort. (3) 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 metric 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 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 noise can become more intrusive. 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. (2)
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
North Fontana Industrial Complex (Acacia) Noise Impact Analysis
14283-07 (Acacia) 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. (4)
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. (2)
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)
2.4 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
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 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 block the line-
of-sight path of sound from the noise source.

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
Approximately sixteen 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 may occur. Twenty to thirty percent of the population will not complain even in very
severe noise environments. (7 pp. 8-6) Thus, a variety of reactions can be expected from people
exposed to any given noise environment.
Surveys have shown that community response to noise varies from no reaction to vigorous action
for newly introduced noises averaging from 10 dB below existing to 25 dB above existing. (8)
According to research originally published in the Noise Effects Handbook (7), the percentage of
high annoyance ranges from approximately 0 percent at 45 dB or less, 10 percent are highly
annoyed around 60 dB, and increases rapidly to approximately 70 percent being highly annoyed
at approximately 85 dB or greater. 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 is considered barely perceptible, and changes of 5 dBA are
considered readily perceptible. (4)

2.8 VIBRATION
Per the Federal Transit Administration (FTA) Transit Noise Impact 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
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 CITY OF FONTANA GENERAL PLAN NOISE ELEMENT
The City of Fontana General Plan was updated on November 13, 2018. (10) 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:
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.

3.3 OPERATIONAL NOISE STANDARDS
Although the Project site is located within the City of Fontana, noise-sensitive receivers
potentially impacted by operational noise activities are also located in the City of Rialto.
However, the City of Rialto Municipal Code does not identify specific exterior noise level
standards. Therefore, the City of Fontana standards are used in this noise study to assess the
potential impacts at adjacent sensitive receiver locations consistent with Section 9.50.050[B] of
the City Rialto Municipal Code.
To analyze noise impacts originating from a designated fixed location or private property such as
the North Fontana Industrial Complex (Acacia) 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.
3.3.1 CITY OF FONTANA EXTERIOR NOISE STANDARDS
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. (11)

"Daytime" = 7:00 a.m. to 10:00 p.m.; "Nighttime" = 10:00 p.m. to 7:00 a.m.
3.4 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) of the city’s Municipal Code,
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. (12) 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 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. The City of Rialto Municipal Code does not identify
specific construction noise level standards, therefore, the City of Fontana standards are used in
this noise study to assess the potential impacts at adjacent sensitive receiver locations consistent
with Section 9.50.050[B] of the City Rialto Municipal Code, which states that construction
activities are permitted between the hours of 7:00 a.m. to 5:30 p.m. Monday through Friday from
October 1st to April 30th, 6:00 a.m. to 7:00 p.m. Monday through Friday from May 1st to
September 30th, and 8:00 a.m. to 5:00 p.m. on Saturdays any time of year; with no activity
allowed on Sundays or state holidays. (13).
3.5 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 construction of the North Fontana Industrial
Complex (Acacia), vibration-generating activities are appropriately evaluated against standards
established under a City’s Municipal Code, if such standards exist. However, the City of Fontana
and the City of Rialto do not identify specific vibration level limits. Therefore, for analysis
purposes, the Caltrans Transportation and Construction Vibration Guidance Manual, (14 p. 38)
Table 19, vibration damage are used in this noise study to assess potential temporary
construction-related impacts at adjacent building locations. The nearest noise sensitive 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).

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?
4.1 NOISE LEVEL INCREASES (THRESHOLD A)
Noise level increases resulting from the Project are evaluated based on the Appendix G CEQA
Guidelines. Under CEQA, consideration must be given to the magnitude of the increase, the
existing baseline ambient noise levels, and the location of 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) This is primarily
because of the wide variation in individual thresholds of annoyance and differing individual
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, a readily perceptible 5 dBA or greater
project-related noise level increase is considered a significant impact when the without project
noise levels are below 60 dBA. 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
North Fontana Industrial Complex (Acacia) Noise Impact Analysis
14283-07 (Acacia) Noise Study
18
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 baseline 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 (baseline) 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 (4 p. 9) and Caltrans (17 p. 2_48).
4.2 VIBRATION (THRESHOLD B)
As described in Section 3.5, the vibration impacts originating from the construction of North
Fontana Industrial Complex (Acacia), vibration-generating activities are appropriately evaluated
using the Caltrans vibration damage thresholds to assess potential temporary construction-
related impacts at adjacent building locations. The nearest noise sensitive 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).
4.3 CEQA GUIDELINES NOT FURTHER ANALYZED (THRESHOLD C)
CEQA Noise Threshold C applies when there are nearby public and private airports and/or air
strips and focuses on land use compatibility of the Project to nearby airports and airstrips. The
Project site is not located within two miles of an airport or airstrip. The closest airport is the
Ontario International Airport (ONT) located roughly 10.8 miles southwest of the Project site. As
such, the Project site would not be exposed to excessive noise levels from airport operations,
and therefore, impacts are considered less than significant, and no further noise analysis is
conducted in relation to Appendix G to the CEQA Guidelines, Noise Threshold C.

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, January 12th, 2022. 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 equivalent daytime and nighttime hourly noise
levels. 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. (2) 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

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 estimate 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) This methodology is commonly
used to describe the off-site traffic noise levels throughout California and is consistent with the
City of Fontana General Plan Noise Element.
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)
6.1.1 OFF-SITE TRAFFIC NOISE PREDICTION MODEL INPUTS
Table 6-1 presents the roadway parameters used to assess the Project’s off-site transportation
noise impacts. Table 6-1 identifies the six off-site 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, and the posted vehicle speeds. The ADT volumes used in this study
area presented on Table 6-2 are based on North Fontana Industrial Complex (Acacia) Traffic Study
by Urban Crossroads, Inc. for the following traffic scenarios. (22)
1. Existing (2021)
2. Existing (2021) plus Project (E+P)
3. Existing plus Ambient Growth without Project (EA)
4. Existing plus Ambient Growth with Project (EAP) (Acacia + Shea Sites)
5. Opening Year Cumulative (2024) without Project (OYC)
6. Opening Year Cumulative (2024) with Project (OYCP)
North Fontana Industrial Complex (Acacia) Noise Impact Analysis
14283-07 (Acacia) Noise Study
26
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 at the boundary of the right-of-way of the receiving adjacent
land use, 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.

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 North Fontana Industrial Complex (Acacia)
Traffic Impact Analysis. (22) 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 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 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 to 7-6 present a summary of the exterior traffic noise levels for each traffic condition.
Appendix 7.1 includes the traffic noise level contours worksheets.

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 for informational purposes and to fully analyze all the existing traffic
scenarios identified in the Traffic Study. However, the analysis of existing off-site traffic noise
levels plus traffic noise generated by the proposed Project scenario will not actually occur since
the Project would not be fully constructed and operational until 2024 conditions. Table 7-1
shows the Existing without Project conditions CNEL noise levels. The Existing without Project
exterior noise levels range from 59.3 to 76.5 dBA CNEL, without accounting for any noise
attenuation features such as noise barriers or topography. Table 7-2 shows the Existing with
Project conditions ranging from 60.1 to 76.6 dBA CNEL. Table 7-7 shows that the Project off-site
traffic noise level increases range from 0.0 to 0.8 dBA CNEL on the study area roadway segments.
Based on the significance criteria for off-site traffic noise presented in Section 4.1, land uses
adjacent to the study area roadway segments would experience less than significant noise level
impacts due to unmitigated Project-related traffic noise levels.
7.3 EA TRAFFIC NOISE LEVEL INCREASES
Table 7-3 presents the EA 2024 without Project conditions CNEL noise levels. The EA without
Project exterior noise levels range from 59.6 to 76.7 dBA CNEL, without accounting for any noise
attenuation features such as noise barriers or topography. Table 7-4 shows that the EA with
Project conditions will range from 60.3 to 76.9 dBA CNEL. Table 7-8 shows that the Project off-
site traffic noise level increases range from 0.0 to 0.7 dBA CNEL on the study area roadway
segments.
Based on the significance criteria for off-site traffic noise presented in Section 4.1, land uses
adjacent to the study area roadway segments would experience less than significant noise level
impacts due to unmitigated Project-related traffic noise levels.

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, five 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 4893 Condor Avenue,
approximately 58 feet north of the Project site. R1 is placed in the private outdoor living
areas (backyard) facing the Project site. 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 3404 North Flame Tree
Avenue in the City of Rialto, approximately 342 feet east of the Project site. R2 is placed
in the private outdoor living areas (backyard) facing the Project site. 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 2895 West Fairview Drive
in the City of Rialto, approximately 1,171 feet southeast of the Project site. R3 is placed
in the private outdoor living areas (backyard) facing the Project site. A 24-hour noise
measurement was taken near this location, L2, to describe the existing ambient noise
environment.
R4: Location R4 represents the existing noise sensitive residence at 16696 Avanti Lane,
approximately 1,384 feet southwest of the Project site. R4 is placed in the private outdoor
living areas (backyard) facing the Project site. A 24-hour noise measurement was taken
near this location, L3, to describe the existing ambient noise environment.

R5: Location R5 represents the existing noise sensitive Gabion Ranch Woodridge at 16502
Casa Grande Avenue, approximately 1,547 feet southwest of the Project site. Since there
are no private outdoor living areas (backyards) facing the Project site, receiver R5 is placed
at the building façade. A 24-hour noise measurement was taken near this location, L4, 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 North
Fontana Industrial Complex (Acacia) 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 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 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.
4 Truck Movements are calculate based on the number of events by time of day (See Table 9-2).
9.2.2 LOADING DOCK ACTIVITY
The reference loading dock activities are intended to describe the typical outdoor operational
noise activities associated with the Project. This includes truck idling, reefer activity (refrigerator
truck/cold storage), deliveries, backup alarms, trailer docking including a combination of tractor
trailer semi-trucks, two-axle delivery trucks, and background operation activities. Since the noise
levels generated by cold storage loading dock activity can be slightly higher due to the use of
refrigerated trucks or reefers, this analysis conservatively assumes that all loading dock activity
is associated with cold storage facilities, even though only 20 percent cold storage is anticipated.
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
North Fontana Industrial Complex (Acacia) Noise Impact Analysis
14283-07 (Acacia) Noise Study
40
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
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 long-term 29-hour reference noise level
measurement was collected in the center of activity within the staff parking lot of a warehouse
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.
9.2.7 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.
Consistent with the North Fontana Industrial Complex (Acacia) Traffic Study prepared by Urban
Crossroads, Inc., the Project is expected to generate a total of approximately 132 two-way truck
trips per day (22). Using the estimated number of truck trips in combination with time-of-day
vehicle splits, the number of truck movements were calculated. As shown on Table 9-2, this
information is then used to calculate the truck movements operational noise source activity
based on the number of events by time of day.

6 Calculated time of day entry gate and truck movements by location.
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 CadnaA noise analysis to account for mixed ground
representing 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.
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.
The daytime hourly noise levels at the off-site receiver locations are expected to range from 41.3
to 47.8 dBA Leq.

Table 9-4 shows the Project operational noise levels during the nighttime hours of 10:00 p.m. to
7:00 a.m. The nighttime hourly noise levels at the off-site receiver locations are expected to
range from 40.2 to 46.7 dBA Leq. The differences between the daytime and nighttime noise levels
are largely related to the estimated duration of noise activity as outlined in Table 9-1 and
Appendix 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 North Fontana Industrial Complex (Acacia) 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. - 10:00 p.m.; "Nighttime" = 10:00 p.m. - 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. (2) 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 Table 9-6, the Project will generate a daytime noise
operational level increase ranging from 0.5 to 1.0 dBA Leq at the nearest receiver locations. Table
9-7 shows that the Project will generate a nighttime operational noise level increase ranging from
0.9 to 3.3 dBA Leq at the nearest receiver locations. A review of the operational noise level
increases shows that the nighttime increases are somewhat higher than the daytime increases.
This is largely due to the lower nighttime ambient conditions that when combined with the
Project produce a higher relative increase.
The 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
The FTA Transit Noise and Vibration Impact Assessment Manual recognizes that construction
projects are accomplished in several different stages and outlines the procedures for assessing
noise impacts during construction. Each stage has a specific equipment mix, depending on the
work to be completed during that stage. As a result of the equipment mix, each stage has its own
noise characteristics; some stages have higher continuous noise levels than others, and some
have higher impact noise levels than others. The Project construction activities are expected to
occur in the following stages:
• Site Preparation
• Grading
• Building Construction
• Paving
• Architectural Coating
10.2 CONSTRUCTION REFERENCE NOISE LEVELS
To describe construction noise activities, this construction noise analysis was prepared using
reference construction equipment noise levels from the Federal Highway Administration (FHWA)
published the Roadway Construction Noise Model (RCNM), which includes a national database
of construction equipment reference noise emission levels. (23) The RCNM equipment database,
provides a comprehensive list of the noise generating characteristics for specific types of
construction equipment. In addition, the database provides an acoustical usage factor to
estimate the fraction of time each piece of construction equipment is operating at full power
(i.e., its loudest condition) during a construction operation.

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 nearby sensitive receiver
locations were completed. Consistent with FTA guidance for general construction noise
assessment, Table 10-1 presents the combined noise levels for the loudest construction
equipment, assuming they operate at the same time. As shown on Table 10-2, the construction
noise levels are expected to range from 36.3 to 59.2 dBA Leq at the nearby receiver locations.
Appendix 10.1 includes the detailed CadnaA construction noise model inputs.

Project site boundary to the nearest receiver locations. CadnaA construction noise model inputs are included in
Appendix 10.1.
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. 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.

5 Do the estimated Project construction noise levels exceed the construction noise level threshold during the
specified hours mentioned in The City of Fontana Municipal Code Section 18-63(7)?
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 pad 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.
10.5.1 NIGHTTIME CONCRETE POUR REFERENCE NOISE LEVEL MEASUREMENTS
To estimate the noise levels due to nighttime concrete pour activities, sample reference noise
level measurements were taken during a nighttime concrete pour at a construction site. Urban
Crossroads, Inc. collected short-term nighttime concrete pour reference noise level
measurements during the noise-sensitive nighttime hours between 1:00 a.m. to 2:00 a.m. The
reference noise levels describe the expected concrete pour noise sources that may include
concrete mixer truck movements and pouring activities, concrete paving equipment, rear
mounted concrete mixer truck backup alarms, engine idling, air brakes, generators, and workers
communicating/whistling.
To describe the nighttime concrete pour noise levels associated with the construction of the
North Fontana Industrial Complex (Acacia), this analysis relies on reference sound power level of
100.3 dBA Lw. While the Project noise levels will depend on the actual duration of activities and

specific equipment fleet in use at the time of construction, the reference sound power level of
100.3 dBA Lw is used to describe the expected Project nighttime concrete pour noise activities.

10.5.2 NIGHTTIME CONCRETE POUR NOISE LEVEL COMPLIANCE
As shown on Table 10-4, the noise levels associated with the nighttime concrete pour activities
are estimated to range from 29.1 to 47.8 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.

4 Do the estimated Project construction noise levels exceed the nighttime construction noise level
threshold?
10.6 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 human response (annoyance) and
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

Table 10-6 presents the expected Project related vibration levels at the nearby receiver locations.
At distances ranging from 58 to 1,547 feet from Project construction activities, construction
vibration velocity levels are estimated to range from 0.000 to 0.025 in/sec PPV. Based on
maximum acceptable continuous vibration threshold of 0.3 PPV (in/sec), the typical Project
construction vibration levels will fall below the building damage thresholds at all the noise
sensitive receiver locations. Therefore, the Project-related vibration impacts are considered less
than significant during typical construction activities at the Project site. Moreover, the vibration
levels reported at the 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 perimeter.
