MEMORANDUM
DATE: June 8, 2023
TO: Aaron Anderson, Public Storage
FROM: J.T. Stephens, Principal
Moe Abushanab, Noise Engineer
SUBJECT: Noise and Vibration Impact Analysis: Proposed Public Storage Redevelopment
Project in Fontana, California
INTRODUCTION AND PROJECT DESCRIPTION
This noise and vibration impact analysis has been prepared to evaluate the potential impacts
associated with the proposed Public Storage Redevelopment Project (project) in the City of Fontana
(City), San Bernardino County, California . This report is intended to satisfy the City’s requirement for
a project-specific noise and vibration impact analysis and examines the impacts of the proposed
project to the existing noise-sensitive uses adjacent to the project site. To properly account for the
impacts associated with the proposed project, existing noise levels are assessed based on noise
measurement data gathered in the vicinity of the project site (from October 24, 2022, to October
25, 2022) and project-related noise and vibration levels generated are based on estimated
construction equipment. Traffic volumes from the Trip Generation Analysis for the Public Storage
Fontana Project1 and additional stationary sources on the project site were also evaluated.
Location and Description
The 5.33-acre project site is located at 17173 Valley Boulevard in Fontana. Figure 1 shows the
project location and Figure 2, Site Plan, provides an overview of the proposed site plan (all figures
are in Attachment A).
Public Storage owns and operates the self-storage facility at 17173 Valley Blvd. The property includes
a vacant portion on the west side of the existing facility. This vacant portion is partially paved and is
used for truck parking for the adjacent hotel, which was approved as part of Design Review No. 94-
036. This area sits behind the SureStay Hotel, between the hotel parking and the freeway.
The proposed project includes construction of a new three-story self-storage building on the vacant
portion of the property including new parking, landscaping, and lighting. The project includes
demolition of the existing two-story building at the existing entrance to the self-storage facility and
construction of a new one-story office. Parking and access in the entrance area will be reconfigured
to meet the City’s form-based code. Landscaping will also be added to this area.

The existing buildings include about 90,170 SF of self-storage including the rental office. One existing
two story self-storage building of 9,298 SF would be demolished to provide for fire access to the new
three-story building of approximately 109,566 SF. The proposed building will be climate controlled
and all the storage units in the new building will be accessible only from the inside of the building. In
addition, the new building would be all electric and would not use natural gas.
The existing two-story self-storage building of 5,724 SF that includes the existing rental office, as well
as portions of two one-story self-storage buildings totaling 1,432 SF will be demolished to provide
room for the new one-story rental office building. The new rental office will include 1,268 SF. The
parking and circulation at the entrance to the facility on Valley Boulevard will also be reconfigured to
a better layout for customers. Parking for the new three-story building will be provided on the east
side of the building, adjacent to the loading lobby for the building.
Parking for the new three-story self-storage building would be provided on the east side of the
building, adjacent to the loading lobby. The operational noise analysis for the proposed project
anticipates truck loading and unloading activities associated with the project would occur only in the
parking stalls located east of the proposed building. Nine semi-trailer truck parking stalls currently
located at the southwestern portion of the project site serve patrons of the neighboring hotel and are
not part of the self-storage facility. The proposed three-story self-storage building would be
constructed in the area currently occupied by the truck parking stalls, so they would be relocated to
the north of the new three-story self-storage building in order to facilitate an existing shared
easement agreement between the Project Applicant and hotel owner. Truck parking and loading and
unloading activities in the semi-trailer truck parking stalls to be relocated north of the proposed self-
storage building would result from hotel operations and not from operation of the proposed project.
Therefore, these activities are not included in the operational noise analysis.
It is expected that construction of the project would start in May 2024 and be completed in April 2025.
Based on the preliminary grading plans, 1,000 cubic yards of soil would be imported. Demolition,
grading, and building activities would involve the use of construction equipment such as rubber-tired
dozers, tractors/loaders/backhoes, excavators, graders, scrapers, cranes, forklifts, generators,
welders, air compressors, and paving equipment.
METHODOLOGY
The evaluation of noise impacts associated with the proposed project includes the following:
• A determination of the short-term construction noise and vibration levels at off-site noise-
sensitive uses and comparison to the City’s General Plan and Municipal Code Ordinance
requirements;
• A determination of the long-term noise levels at off-site noise sensitive uses and comparison of
those levels to the City's pertinent noise standards; and
• If necessary, a determination of required mitigation measures, such as noise barriers, to reduce
long-term noise impacts from all sources.

CHARACTERISTICS OF SOUND
Noise is usually defined as unwanted sound. Noise consists of any sound that may produce
physiological or psychological damage and/or interfere with communication, work, rest, recreation,
and sleep.
To the human ear, sound has two significant characteristics: pitch and loudness. Pitch is generally an
annoyance, while loudness can affect the ability to hear. Pitch is the number of complete vibrations,
or cycles per second, of a wave resulting in the tone’s range from high to low. Loudness is the
strength of a sound that describes a noisy or quiet environment and is measured by the amplitude
of the sound wave. Loudness is determined by the intensity of the sound waves combined with the
reception characteristics of the human ear. Sound intensity refers to how hard the sound wave
strikes an object, which in turn produces the sound’s effect. This characteristic of sound can be
precisely measured with instruments. The analysis of a project defines the noise environment of the
project area in terms of sound intensity and its effect on adjacent sensitive land uses.
Measurement of Sound
Sound intensity is measured through the A-weighted scale to correct for the relative frequency
response of the human ear. That is, an A-weighted noise level de-emphasizes low and very high
frequencies of sound similar to the human ear’s de-emphasis of these frequencies. Unlike linear
units (e.g., inches or pounds), decibels are measured on a logarithmic scale representing points on a
sharply rising curve.
For example, 10 decibels (dB) is 10 times more intense than 1 dB, 20 dB is 100 times more intense
than 1 dB, and 30 dB is 1,000 times more intense than 1 dB. Thirty decibels (30 dB) represent
1,000 times as much acoustic energy as 1 dB. The decibel scale increases as the square of the
change, representing the sound pressure energy. A sound as soft as human breathing is about
10 times greater than 0 dB. The decibel system of measuring sound gives a rough connection
between the physical intensity of sound and its perceived loudness to the human ear. A 10 dB
increase in sound level is perceived by the human ear as only a doubling of the loudness of the
sound. Ambient sounds generally range from 30 dB (very quiet) to 100 dB (very loud).
Sound levels are generated from a source, and their decibel level decreases as the distance from
that source increases. Sound dissipates exponentially with distance from the noise source. For a
single-point source, sound levels decrease approximately 6 dB for each doubling of distance from
the source. This drop-off rate is appropriate for noise generated by stationary equipment. If noise is
produced by a line source (e.g., highway traffic or railroad operations), the sound decreases 3 dB for
each doubling of distance in a hard site environment. Similarly, line sources with intervening
absorptive vegetation or line sources that are located at a great distance to the receptor would
decrease 4.5 dB for each doubling of distance.
There are many ways to rate noise for various time periods, but an appropriate rating of ambient
noise affecting humans also accounts for the annoying effects of sound. The equivalent continuous
sound level (Leq) is the total sound energy of time-varying noise over a sample period. However, the
predominant rating scales for human communities in the State of California are the Leq and
Community Noise Equivalent Level (CNEL) or the day-night average noise level (Ldn) based on
6/8/23 «\\lsaazfiles.file.core.windows.net\projects\PUB2202\Technical Studies\Noise\Product\Noise and Vibration Memo_060823.docx» 4
A-weighted decibels (dBA). CNEL is the time-varying noise over a 24-hour period, with a
5 dBA weighting factor applied to the hourly Leq for noises occurring from 7:00 p.m. to 10:00 p.m.
(defined as relaxation hours), and a 10 dBA weighting factor applied to noises occurring from
10:00 p.m. to 7:00 a.m. (defined as sleeping hours). Ldn is similar to the CNEL scale but without the
adjustment for events occurring during the evening hours. CNEL and Ldn are within 1 dBA of each
other and are normally interchangeable. The City uses the CNEL noise scale for long-term noise
impact assessment.
Other noise rating scales of importance when assessing the annoyance factor include the maximum
instantaneous noise level (Lmax), which is the highest exponential time-averaged sound level that
occurs during a stated time period. The noise environments discussed in this analysis for short-term
noise impacts are specified in terms of maximum levels denoted by Lmax, which reflects peak
operating conditions and addresses the annoying aspects of intermittent noise. Lmax is often used
together with another noise scale or noise standards in terms of percentile noise levels in noise
ordinances for enforcement purposes. For example, the L10 noise level represents the noise level
exceeded 10 percent of the time during a stated period. The L50 noise level represents the median
noise level (i.e., half the time the noise level exceeds this level, and half the time it is less than this
level). The L90 noise level represents the noise level exceeded 90 percent of the time and is
considered the background noise level during a monitoring period. For a relatively constant noise
source, the Leq and L50 are approximately the same.
Noise impacts can be described in three categories. The first category is audible impacts that refer
to increases in noise levels noticeable to humans. Audible increases in noise levels generally refer to
a change of 3.0 dB or greater because this level has been found to be barely perceptible in exterior
environments. The second category, potentially audible, refers to a change in the noise level
between 1.0 and 3.0 dB. This range of noise levels has been found to be noticeable only in
laboratory environments. The last category is changes in noise levels of less than 1.0 dB, which are
inaudible to the human ear. Only audible changes in existing ambient or background noise levels are
considered potentially significant.
Physiological Effects of Noise
Physical damage to human hearing begins at prolonged exposure to noise levels higher than 85 dBA.
Exposure to high noise levels affects the entire system, with prolonged noise exposure in excess of
75 dBA increasing body tensions, thereby affecting blood pressure and functions of the heart and
the nervous system. In comparison, extended periods of noise exposure above 90 dBA would result
in permanent cell damage. When the noise level reaches 120 dBA, a tickling sensation occurs in the
human ear even with short-term exposure. This level of noise is called the threshold of feeling. As
the sound reaches 140 dBA, the tickling sensation is replaced by the feeling of pain in the ear. This is
called the threshold of pain. A sound level of 160–165 dBA will result in dizziness or loss of
equilibrium. The ambient or background noise problem is widespread and generally more
concentrated in urban areas than in outlying less developed areas.
Table A lists full definitions of acoustical terms, and Table B shows common sound levels and their
sources.

Table A: Definitions of Acoustical Terms
Term Definitions
Decibel, dB A unit of level that denotes the ratio between two quantities proportional to power, the number of
decibels is 10 times the logarithm (to the base 10) of this ratio.
Frequency, Hz Of a function periodic in time, the number of times that the quantity repeats itself in one second (i.e.,
number of cycles per second).
A-Weighted Sound Level, dBA The sound level obtained by use of A-weighting. The A-weighting filter deemphasizes the very low and very high frequency components of the sound in a manner similar to the frequency components of the
sound in a manner similar to the frequency response of the human ear and correlates well with
subjective reactions to noise. All sound levels in this assessment are A-weighted, unless reported otherwise.
L01, L10, L50, L90 The fast A-weighted noise levels equaled or exceeded by a fluctuating sound level for 1 percent, 10
percent, 50 percent, and 90 percent of a stated time period.
Equivalent Continuous
Noise Level, Leq
The level of a steady sound that, in a stated time period and at a stated location, has the same
A-weighted sound energy as the time varying sound.
Community Noise Equivalent Level, CNEL The 24-hour A-weighted average sound level from midnight to midnight, obtained after the addition of 5 dB to sound levels occurring in the evening from 7:00 p.m. to 10:00 p.m. and after the addition of
10 dB to sound levels occurring in the night between 10:00 p.m. and 7:00 a.m.
Day/Night Noise Level,
Ldn
The 24-hour A-weighted average sound level from midnight to midnight, obtained after the addition
of 10 dB to sound levels occurring in the night between 10:00 p.m. and 7:00 a.m.
Lmax, Lmin The maximum and minimum A-weighted sound levels measured on a sound level meter, during a
designated time interval, using fast time averaging.
Ambient Noise Level The all-encompassing noise associated with a given environment at a specified time, usually a composite of sound from many sources at many directions, near and far; no particular sound is
dominant.
Intrusive The noise that intrudes over and above the existing ambient noise at a given location. The relative
intrusiveness of a sound depends upon its amplitude, duration, frequency, and time of occurrence and tonal or informational content, as well as the prevailing ambient noise level.

CHARACTERISTICS OF VIBRATION
Vibration refers to ground-borne noise and perceptible motion. Ground-borne vibration is almost
exclusively a concern inside buildings and is rarely perceived as a problem outdoors, where the
motion may be discernible. Typically, there is more adverse reaction to effects associated with the
shaking of a building. Vibration energy propagates from a source through intervening soil and rock
layers to the foundations of nearby buildings. The vibration then propagates from the foundation
throughout the remainder of the structure. Building vibration may be perceived by occupants as the
motion of building surfaces, the rattling of items on shelves or hanging on walls, or a low-frequency
rumbling noise. The rumbling noise is caused by the vibration of walls, floors, and ceilings that
radiate sound waves.
Typical sources of ground-borne vibration are construction activities (e.g., blasting, pile driving, and
operating heavy-duty earthmoving equipment), steel-wheeled trains, and occasional traffic on rough
6/8/23 «\\lsaazfiles.file.core.windows.net\projects\PUB2202\Technical Studies\Noise\Product\Noise and Vibration Memo_060823.docx» 7
roads. Problems with both ground-borne vibration and noise from these sources are usually
localized to areas within approximately 100 feet (ft) of the vibration source, although there are
examples of ground-borne vibration causing interference out to distances greater than 200 ft (FTA
2018)2. When roadways are smooth, vibration from traffic, even heavy trucks, is rarely perceptible.
It is assumed for most projects that the roadway surface will be smooth enough that ground-borne
vibration from street traffic will not exceed the impact criteria; however, the construction of the
project could result in ground-borne vibration that may be perceptible.
Ground-borne vibration has the potential to damage buildings. Although it is very rare for typical
construction activities to cause even cosmetic building damage, it is not uncommon for construction
processes such as blasting and pile driving to cause vibration of sufficient amplitudes to damage
nearby buildings (FTA 2018)2. Ground-borne vibration that may resulting in damage is usually
measured in terms of peak particle velocity (PPV).
APPLICABLE NOISE STANDARDS
The applicable noise standards governing the project site include the criteria in the City’s Noise
Element of the General Plan (Noise Element) and the City of Fontana Municipal Code (FMC).
City of Fontana
Noise Element of the General Plan
The Noise Element provides the City’s goals and policies related to noise, including the land use
compatibility guidelines for community exterior noise environments. The City has identified the
following policies in the 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.
City of Fontana Municipal Code
Operational Noise Standards. This project utilizes the City’s residential noise control guidelines for
determining and mitigating non-transportation or stationary noise source impacts from operations
found in Section 30-469. For residential zoning districts, Section 30-469 indicates that “no use shall
create or cause to be created any sound that exceeds the ambient noise standards outlined in Table
30-469” (Table C below). The performance standards found in Section 30-469 limit the exterior noise
level to 65 dBA Leq during the daytime and nighttime hours at sensitive receiver locations.

Construction Noise Standards. The City 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.
State of California Green Building Standards Code
The State of California’s Green Building Standards Code (CALGreen) contains mandatory measures for
non-residential building construction in Section 5.507 on Environmental Comfort. 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.
Federal Transit Administration
Though the City does not have daytime construction noise level limits for activities that occur with the
specified hours of Section 18-63(b)(7), to determine potential CEQA noise impacts, construction noise
was assessed using criteria from the Transit Noise and Vibration Impact Assessment Manual (FTA
6/8/23 «\\lsaazfiles.file.core.windows.net\projects\PUB2202\Technical Studies\Noise\Product\Noise and Vibration Memo_060823.docx» 9
2018) (FTA Manual)3. Table D shows the FTA’s Detailed Assessment Construction Noise Criteria based
on the composite noise levels per construction phase.

APPLICABLE VIBRATION STANDARDS
The following information provides standards to which potential vibration impacts will be
compared.
City of Fontana General Plan Update
As discussed in the The City does not specify the vibration level that can be felt but indicates
predicted vibration levels that would occur during construction hours specified pursuant to
Municipal Code Section 18-63(b)(7) (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) are considered “an acceptable intrusion
of the ambient noise within that project area.”4
Federal Transit Administration
Vibration standards included in the Federal Transit Administration’s (FTA) Transit Noise and
Vibration Impact Assessment Manual (2018) (FTA Manual) are used in this analysis for ground-borne
vibration impacts on surrounding buildings.
The criteria for environmental impacts resulting from ground-borne vibration are based on the
maximum levels for a single event. The City’s Municipal Code does not include specific criteria for
assessing vibration impacts associated with damage. Therefore, for the purpose of determining the
significance of vibration impacts experienced at sensitive uses surrounding the project site, the
guidelines within the 2018 FTA Manual have been used to determine vibration impacts (refer to
Table E, below).

The FTA Manual (2018) guidelines show that a vibration level of up to 0.2 in/sec in PPV is considered
safe for non-engineered timber and masonry buildings which are the types of buildings located on
properties adjacent to the project site. Accordingly, the 0.2 in/sec in the PPV threshold was used to
evaluate vibration impacts at the nearest structures to the site.
THRESHOLDS OF SIGNIFICANCE
Based on Guidelines for the Implementation of the California Environmental Quality Act (CEQA),
Appendix G, Public Resources Code, Sections 15000–15387, a project will normally have a significant
effect on the environment related to noise if it will substantially increase the ambient noise levels
for adjoining areas or conflict with adopted environmental plans and the goals of the community in
which it is located.
The State CEQA Guidelines indicate that a project would have a significant impact on noise if it
would result in:
• 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;
• Generation of excessive ground-borne vibration or ground-borne noise levels; or
• 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, expose
people residing or working in the project area to excessive noise levels.
OVERVIEW OF THE EXISTING NOISE ENVIRONMENT
The primary existing noise sources in the project area are transportation facilities, including Valley
Boulevard and San Bernardino Freeway (I-10). In addition, periodic storage operations such as
loading and unloading are audible at the project site.
In order to assess the existing noise conditions in the area, long-term noise measurements were
conducted at the project site. Two long-term, 24-hour measurements were taken from October 24,
2022, to October 25, 2022. The locations of the noise measurements are shown on Figure 3, and the
results are summarized in Table F. Noise measurement data information are provided in Attachment
B of this analysis.

AIRCRAFT NOISE
The project site is approximately 8.8 miles east of Ontario International Airport (ONT). Based on a
review of the maps within the Los Angeles County Airport Land Use Commission [ALUC] website5,
the project site is located well outside the 65 dBA CNEL contour of ONT. Therefore, there would be
no impact from aircraft noise, and no further analysis is necessary.
Sensitive Land Uses in the Project Vicinity
Certain land uses are considered more sensitive to noise than others are. Examples of these include
residential areas, educational facilities, hospitals, childcare facilities, and senior housing. Land uses
adjacent to the project site include the following:
• Northwest: Fontana Medical Center opposite Valley Boulevard, approximately 480 ft from the
project site property line.
• East: Existing Extra Space Storage adjacent to the project site and single-family residential units
located approximately 190 ft from the project site property line.
• South: San Bernardino Freeway (I-10).

PROJECT IMPACT ANALYSIS
The proposed project would result in short-term construction noise and vibration impacts and long-
term mobile source noise and vibration impacts as described below.
Short-Term Construction-Related Impact Analysis
Project construction would result in short-term noise and vibration. Maximum construction noise
would be short-term, generally intermittent depending on the construction phase, and variable
depending on receiver distance from the active construction zone. The duration of various types of
construction noise and vibration would vary from one day to several weeks depending on the phase
of construction. The levels and types of impacts that may occur during construction are described
below.
Construction Noise Analysis
Two types of short-term noise would occur during project construction, including: (1) equipment
delivery and construction worker commutes; and (2) project construction operations.
The first type of short-term construction noise would result from the transport of construction
equipment and materials to the project site and construction worker commutes. These
transportation activities would incrementally raise noise levels on access roads leading to the site. It
is expected that larger trucks used in equipment delivery would generate higher noise impacts than
trucks associated with worker commutes. The single-event noise from equipment trucks passing at a
distance of 50 ft from a sensitive noise receptor would reach a maximum level of 84 dBA Lmax.
However, the pieces of heavy equipment for construction activities would be moved on site just one
time and would remain on site for the duration of each construction phase. This one-time trip, when
heavy construction equipment is moved on and off site, would not add to the daily traffic noise in
the project vicinity. The total number of daily vehicle trips would be minimal when compared to
existing traffic volumes on the affected streets, and the long-term noise level changes associated
with these trips would not be perceptible. Therefore, equipment transport noise and construction-
related worker commute impacts would be short term and would not result in a significant off-site
noise impact. No mitigation is required.
The second type of short-term noise impact is related to noise generated during demolition, site
preparation, grading, building construction, architectural coating, and paving on the project site.
Construction is undertaken in discrete steps, each of which has its own mix of equipment, and
6/8/23 «\\lsaazfiles.file.core.windows.net\projects\PUB2202\Technical Studies\Noise\Product\Noise and Vibration Memo_060823.docx» 13
consequently, its own noise characteristics. These various sequential phases would change the
character of the noise generated on the project site. Therefore, the noise levels vary as construction
progresses. Despite the variety in the type and size of construction equipment, similarities in the
dominant noise sources and patterns of operation allow construction-related noise ranges to be
categorized by work phase. Table G lists the maximum noise levels recommended for noise impact
assessments for typical construction equipment based on a distance of 50 ft between the
construction equipment and a noise receptor. Typical operating cycles for these types of
construction equipment may involve 1–2 minutes of full power operation followed by 3–4 minutes
at lower power settings.

ft = foot/feet
Lmax = maximum instantaneous sound level
In addition to the reference maximum noise level, the usage factor provided in Table G is utilized to
calculate the hourly noise level impact for each piece of equipment based on the following
equation:
−+=50log20.).log(10..)(DFULEequipLeq
where: Leq (equip) = Leq at a receiver resulting from the operation of a single
piece of equipment over a specified time period
E.L. = Noise emission level of the particular piece of equipment at
a reference distance of 50 ft
U.F. = Usage factor that accounts for the fraction of time that the
equipment is in use over the specified period of time
D = Distance from the receiver to the piece of equipment

Each piece of construction equipment operates as an individual point source. Utilizing the following
equation, a composite noise level can be calculated when multiple sources of noise operate
simultaneously:
𝐿𝐿𝐿𝐿𝐿𝐿 (𝑐𝑐𝑐𝑐𝑐𝑐𝑐𝑐𝑐𝑐𝑐𝑐𝑐𝑐𝑐𝑐𝐿𝐿)=10 ∗log10 ��10𝐿𝐿𝐿𝐿10𝐿𝐿
1 �
Table H shows the composite noise levels of the pieces of equipment for each construction phase at
a distance of 50 ft from the construction area. Once composite noise levels are calculated, reference
noise levels can then be adjusted for distance using the following equation: 𝐿𝐿𝐿𝐿𝐿𝐿 (𝑎𝑎𝑐𝑐 𝑑𝑑𝑐𝑐𝑐𝑐𝑐𝑐𝑎𝑎𝑑𝑑𝑐𝑐𝐿𝐿 𝑋𝑋)=𝐿𝐿𝐿𝐿𝐿𝐿 (𝑎𝑎𝑐𝑐 50 𝑓𝑓𝐿𝐿𝐿𝐿𝑐𝑐)−20 ∗lo g10 �𝑋𝑋50�
In general, this equation shows that doubling the distance would decrease noise levels by 6 dBA while
halving the distance would increase noise levels by 6 dBA.

1 Distances are from the average location of construction activity for each phase, assumed to be center of project site. Hotel uses
would be within 10 ft of the edge of construction activity.
dBA Leq = average A-weighted hourly noise level ft = foot/feet
As presented above, Table H shows the construction phases, the expected duration of each phase,
the equipment expected to be used during each phase, the composite noise levels of the equipment
at 50 ft, the distance of the nearest sensitive receptor from the average location of construction
activities (a distance of 160 ft from center of project site), and noise levels expected during each
phase of construction. These noise level projections do not take into account intervening
topography or barriers. Attachment C provides construction noise calculations.
6/8/23 «\\lsaazfiles.file.core.windows.net\projects\PUB2202\Technical Studies\Noise\Product\Noise and Vibration Memo_060823.docx» 15
It is expected that average noise levels during construction at the nearest sensitive receptor, hotel
to the west, would approach 78 dBA Leq during the site preparation phase, which would take place
for a duration of approximately 10 days. Average noise levels during other construction phases
would range from 64 dBA Leq to 77 dBA Leq. Noise levels at the nearest off-site commercial uses
(Extra Space Storage) to the east would reach an average noise level of 79 dBA Leq during the
daytime hours. These predicted noise levels would only occur when all construction equipment is
operating simultaneously and, therefore, these noise levels are assumed to be conservative in
nature.
Although the project construction-related short-term noise levels have the potential to be higher
than the ambient noise in the project vicinity, it would cease to occur once the project construction
is completed. Furthermore, the construction-related noise levels would be below the 80 dBA Leq and
85 dBA Leq criteria established by FTA for residential and commercial uses, respectively. Compliance
with the requirements of the City of Fontana Noise Ordinance, which states that construction
activities shall only occur between the hours of 7:00 a.m. and 6:00 p.m., Monday through Friday,
and between 8:00 a.m. and 5:00 p.m. on Saturday, and with incorporation of best business practices
for noise reduction, the overall noise levels generated will be minimized, and construction noise
impacts would be less than significant. No mitigation is required.
Construction Vibration Building Damage Potential
Ground-borne noise and vibration from construction activity would be low. Table I provides
reference PPV values and vibration levels (in terms of VdB) from typical construction vibration
sources at 25 ft. While there is currently limited information regarding vibration source levels
specific to the equipment which would be used for the project, to provide a comparison of vibration
levels expected for a project of this size, a large bulldozer would generate 0.089 PPV (in/sec) of
ground-borne vibration when measured at 25 ft, based on the FTA Manual. As shown previously in
Table E, it would take a minimum of 0.2 PPV (in/sec) to cause any potential building damage to non-
engineered timber and masonry buildings.

The distance to the nearest buildings for vibration impact analysis is measured between the nearest
off-site buildings and the project construction boundary (assuming the construction equipment
would only be used at or near the project setback line). The formula for vibration transmission is
provided below:
PPVequip = PPVref x (25/D)1.5
The closest structure to external construction activities is the hotel to the west, approximately 8 ft
from the western project construction boundary. Construction activities on the eastern portion of
the project would only include tenant improvement within existing buildings which are not expected
to generate noticeable vibration levels to the Extra Space Storage facility immediately adjacent to
the east. Using the reference data from Table I and the equation above, it is expected that vibration
levels generated by dump trucks and other large equipment would generate ground-borne vibration
levels of 0.352 PPV (in/sec) or higher at the closest structures to the project site. This vibration level
would exceed the 0.2 in/sec PPV threshold considered safe for non-engineered timber and masonry
buildings, which would result in a potentially significant impact. The distance from large
construction equipment with a reference vibration level of 0.089 in/sec PPV at 25 feet for which the
0.2 in/sec threshold would no longer be exceeded is 15 feet. Vibration levels at all other buildings
would be lower. Therefore, construction would not result in any vibration damage, and impacts
would be less than significant with the incorporation of Mitigation Measure NOI-1, as detailed
below.
Mitigation Measure NOI-1 Construction Vibration Damage. Due to the close proximity to
surrounding structures, the City of Fontana (City) Director of
Community Development, or designee, shall verify prior to issuance
of demolition or grading permits, that the approved plans require
that the construction contractor shall implement the following
mitigation measures during project construction activities to ensure
that damage does not occur at surrounding structures:
• Identify structures that are located within 15 feet (ft) of heavy
construction activities and that have the potential to be affected
by ground-borne vibration. This task shall be conducted by a
qualified structural engineer as approved by the City’s Director of
Community Development, or designee.
• Once the construction equipment list finalized, a comparison of
the proposed equipment to be used and the assumed equipment
vibration levels presented in Table 7-4 of the Federal Transit
Administration Noise and Vibration Impact Assessment Manual –
FTA Report No. .0123 shall be completed. If it is determined that
the proposed equipment would generate lower vibration levels
than assumed, further vibration mitigation would not be
necessary. However, if levels would potentially exceed the FTA
Damage Criteria presented in Table 7-5 of the Federal Transit
Administration Noise and Vibration Impact Assessment Manual –
6/8/23 «\\lsaazfiles.file.core.windows.net\projects\PUB2202\Technical Studies\Noise\Product\Noise and Vibration Memo_060823.docx» 17
FTA Report No. .0123, the applicant shall develop a vibration
monitoring and construction contingency plan for approval by
the City Director of Community Development, or designee, to
identify structures where monitoring would be conducted; set up
a vibration monitoring schedule; define structure-specific
vibration limits; and address the need to conduct photo,
elevation, and crack surveys to document before and after
construction conditions. Construction contingencies would be
identified for when vibration levels approached the limits.
• If a vibration monitoring and construction contingency plan is
deemed necessary, monitor vibration during initial construction
activities would be required. Monitoring results may indicate the
need for more or less intensive measurements.
• When vibration levels approach limits, suspend construction and
implement contingencies as identified in the approved vibration
monitoring and construction contingency plan to either lower
vibration levels or secure the affected structures.
Long-Term Off-Site Traffic Noise Impact Analysis
In order to assess the potential traffic impacts related to the proposed project, LSA estimates that
the proposed project would result in a net increase of 137 average daily trips (ADT) based on the
proposed increase in square footage. Based on the ADTs provided in Exhibit 9.5, Average Daily Trips,
of the Community Mobility and Circulation Element of the Fontana General Plan (Community
Mobility and Circulation Element 2018)6, the ADT along Valley Boulevard in the vicinity of the
project is approximately between 20,001 – 30,000 based on projections for the year 2016. While the
existing ADT is likely higher, using 20,001 ADT as the existing count would be a conservative
approach. The following equation was used to determine potential impacts of the project:
Change in CNEL = 10 log10 [Ve+p/Vexisting]
Where: Vexisting = the existing daily volume
Ve+p = existing daily volumes plus project
Change in CNEL = the increase in noise level due to the project
The results of the calculations show that an increase of less than 0.03 dBA CNEL is expected along
Valley Boulevard. A noise level increase of less than 3 dBA would not be perceptible to the human
ear; therefore, the traffic noise increase along Valley Boulevard resulting from the proposed project
would be less than significant. No mitigation is required.

Long-Term Operational Noise Impact Analysis
Adjacent off-site land uses would be potentially exposed to stationary-source noise impacts from
the proposed on-site heating, ventilation, and air conditioning (HVAC) equipment and truck
deliveries and loading and unloading activities. The potential noise impacts to off-site sensitive land
uses from the proposed operations are discussed below. To provide a conservative analysis, it is
assumed that within any given hour, 5 heavy trucks would maneuver to park near the loading zone
east of the proposed building. HVAC equipment is expected to run continuously for the duration of a
24-hour period. To determine the future noise impacts from project operations to the noise
sensitive uses, a 3-D noise model, SoundPLAN, was used to incorporate the site topography as well
as the shielding from the proposed building on-site. A graphic representation of the operational
noise impacts is presented in Attachment D.
Heating, Ventilation, and Air Conditioning Equipment
The project is estimated to have three (3) banks of four (4) rooftop HVAC units (total of 12 units) on
the proposed storage building to provide ventilation. The HVAC equipment could operate 24 hours
per day and would generate sound power levels (SPL) of up to 87 dBA SPL or 72 dBA Leq at 5 feet,
based on manufacturer data (Trane)7.
Truck Deliveries and Truck Loading and Unloading Activities
Noise levels generated by delivery trucks would be similar to noise readings from truck loading and
unloading activities, which generate a noise level of 75 dBA Leq at 20 ft based on measurements taken
by LSA (Operational Noise Impact Analysis for Richmond Wholesale Meat Distribution Center [LSA
2016]). During this process, noise levels are associated with the truck engine noise, air brakes, and
back-up alarms. These noise levels would occur for a shorter period of time (less than 5 minutes).
Maximum noise levels that occur during the truck movement process taken by LSA were measured to
be 86 dBA Lmax at a distance of 20 feet.
Tables J and K below show the combined hourly noise levels generated by HVAC equipment and truck
delivery activities at the closest off-site land uses. The project-related noise level impacts would range
from 52.0 dBA Leq to 55.9 dBA Leq at the surrounding sensitive receptors. These levels would be well
below the City’s exterior noise standard of 65 dBA Leq. Because project noise levels would not generate
a noise level by 3 dBA or more or exceed the City’s thresholds, the impact would be less than
significant, and no noise reduction measures are required.

Long-Term Ground-Borne Noise and Vibration from Vehicular Traffic
Because the rubber tires and suspension systems of buses and other on-road vehicles provide
vibration isolation and reduce noise, it is unusual for on-road vehicles to cause ground-borne noise
or vibration. When on-road vehicles cause such effects as the rattling of windows, the source is
almost always airborne noise. Most problems with on-road vehicle-related noise and vibration can
be directly related to a pothole, bump, expansion joint, or other discontinuity in the road surface.
Smoothing the bump or filling the pothole will usually solve the problem. The proposed project
would have roads with smooth pavement and would not result in significant ground-borne noise or
vibration impacts from vehicular traffic. No mitigation is required.
