MEMORANDUM
DATE: November 5, 2025
TO: Stacey Sassaman, Lewis Management Corporation
FROM: Jason Lui, Associate/Senior Noise Specialist
SUBJECT: Noise and Vibration Impact Analysis for the Proposed Enclave at North Fontana
Project in Fontana, California (LSA Project No. 20252531)
INTRODUCTION
This Noise and Vibration Impact Analysis has been prepared to evaluate the potential noise and
vibration impacts and mitigation measures associated with the Enclave at North Fontana Project
(project) in Fontana, California. This memorandum is intended to satisfy the requirements of the
City of Fontana (City) and the California Environmental Quality Act (CEQA) for a project-specific
noise and vibration impact analysis by examining the short-term and long-term noise and vibration
impacts on sensitive uses adjacent to the project site and evaluating mitigation measures that the
project may require. All references cited in this memorandum are included in Attachment A.
Project Location
The 11.99-acre project site is at the northeast corner of Curtis Avenue and Catawba Avenue in the
northern portion of Fontana, San Bernardino County, California. The project location is shown on
Figure 1 (all figures are provided in Attachment B).
Project Description
The proposed project includes the construction of a 153-unit condominium community, with
84 multi-family dwelling units and 69 single-family dwelling units. The proposed project would also
provide private open spaces, landscaped paseos, a central neighborhood park, internal circulation
consisting of six alleys, and frontage improvements along Curtis Avenue consisting of installation of
sidewalk, perimeter wall, decorative signage, and driveway access. The proposed project would also
include a 0.5-acre neighborhood park and approximately 80,190 square feet of landscaped area. The
proposed project would require a General Plan Amendment to the City’s existing General Plan to
change the designations from WMXU-2 Walkable Mixed Use Urban Village to Multi-Family. It would
also require a Zoning Map/Code amendment to rezone the site from Form-Based Code to Multiple
Family (R-3).
Primary access to the project site would be provided via gated entry from Curtis Avenue at Alley A,
with secondary gated exit-only access provided to the west at Alley B, also from Curtis Avenue.
Internal circulation weaves across the site via three north-south internal alleys (from west to east,
Alleys B, A, and C) and three east-west internal alleys (from north to south, Alleys F, E, and D) with
vehicle access to individual condominium units provided either directly from the alleys or by access
11/5/25 «P:\2025\20252531 - Enclave at North Fontana\PRODUCT\Technical Studies\Noise\Noise Memo 11.5.25.docx» 2
drives that spur off the east-west alleys. The proposed project would provide 306 garage parking
spaces and 132 on-site parking spaces dispersed throughout the site for a total of 438 parking
spaces. No driveway parking is proposed. The proposed project would include 139,439 square feet
of asphalt and 34,636 square feet of concrete. Figure 2 shows the site plan.
Construction would include excavation for grading, paving, and construction of the proposed
buildings, parking areas, and the installation of lighting, fencing, landscaping, and utility
connections. During grading, on-site soils would be excavated and recompacted in accordance with
the California Building Code (CBC) to accommodate the proposed residential buildings, as well as
parks and parking areas. As such, grading of the project site would balance soil import/export.
Construction hours would conform to City standards and be limited to 7:00 a.m. to 6:00 p.m.
Monday through Friday.
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 deemphasizes low and very high
frequencies of sound similar to the human ear’s de-emphasis of these frequencies. Decibels (dB),
unlike the linear scale (e.g., inches or pounds), are measured on a logarithmic scale, which is a scale
based on powers of 10.
For example, 10 dB is 10 times more intense than 0 dB, 20 dB is 100 times more intense than 0 dB,
and 30 dB is 1,000 times more intense than 0 dB. Thirty decibels (30 dB) represents 1,000 times as
much acoustic energy as 0 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
11/5/25 «P:\2025\20252531 - Enclave at North Fontana\PRODUCT\Technical Studies\Noise\Noise Memo 11.5.25.docx» 3
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; however, line source noise in a relatively flat
environment with absorptive vegetation decreases 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 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
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.
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 includes audible impacts that
refer to increases in noise levels noticeable to humans. Audible increases in noise levels generally
refer to a change of 3 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 dB and 3 dB. This range of noise levels has been found to be noticeable only in
laboratory environments. The last category includes changes in noise levels of less than 1 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.
11/5/25 «P:\2025\20252531 - Enclave at North Fontana\PRODUCT\Technical Studies\Noise\Noise Memo 11.5.25.docx» 4
As the sound reaches 140 dBA, the tickling sensation is replaced by the feeling of pain in the ear (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 area. Table A lists definitions of acoustical terms, and Table B
shows common sound levels and their sources.
Table A: Definitions of Acoustical Terms
Term Definition
Decibel, dB A unit of noise level that denotes the ratio between two quantities that are
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 1 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
de-emphasizes the very-low-frequency and very-high-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 report
are A-weighted unless reported otherwise.)
L2, L8, L50, L90 The fast A-weighted noise levels that are equaled or exceeded by a fluctuating
sound level 2 percent, 8 percent, 50 percent, and 90 percent of a stated time
period.
Equivalent Continuous Sound 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 Average 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 from 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 on its amplitude,
duration, frequency, time of occurrence, and tonal or informational content, as
well as the prevailing ambient noise level.

FUNDAMENTALS 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, but without the effects associated with the shaking of a building there is
less adverse reaction. 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. Annoyance from vibration often occurs when the vibration exceeds the
threshold of perception by 10 vibration velocity decibels (VdB) or less. This is an order of magnitude
below the damage threshold for normal buildings. 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 roads. Ground-borne vibration
and noise from these sources are usually localized to areas within approximately 100 feet from the
vibration source, although there are examples of ground-borne vibration causing interference out to
distances greater than 200 feet (see the Federal Transit Administration’s [FTA] 2018 Transit Noise
and Vibration Impact Assessment Manual). 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, both construction of a project and freight train operations on railroad tracks could result
in ground-borne vibration that may be perceptible and annoying.
11/5/25 «P:\2025\20252531 - Enclave at North Fontana\PRODUCT\Technical Studies\Noise\Noise Memo 11.5.25.docx» 6
Ground-borne noise is not likely to be a problem because noise arriving via the normal airborne path
will usually be greater than ground-borne noise. Ground-borne vibration has the potential to disturb
people and damage buildings. Although it is very rare for train-induced ground-borne vibration to
cause cosmetic building damage, it is not uncommon for heavy duty construction processes (e.g.,
blasting and pile driving) to cause vibration of sufficient amplitudes to damage nearby buildings (FTA
2018). Ground-borne vibration is usually measured in terms of vibration velocity, either the root-
mean-square (RMS) velocity or peak particle velocity (PPV). The RMS is best for characterizing
human response to building vibration, and PPV is used to characterize potential for damage. Decibel
notation acts to compress the range of numbers required to describe vibration. Vibration velocity
level in decibels is defined as:
Lv = 20 log10 [V/Vref]
where Lv is the VdB, “V” is the RMS velocity amplitude, and “Vref” is the reference velocity
amplitude, or 1 × 10-6 inches/second (in/sec) used in the United States.

City of Fontana
General Plan Noise and Safety Chapter. The City’s General Plan Noise and Safety Chapter (2018)
lists the policies and actions required to meet the City’s noise-related goals. The following lists the
applicable goals, policies, and actions for the proposed project.
• Goal 3. Fontana’s residents are protected from negative effects of “spillover” noise.
o 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.
o 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.
11/5/25 «P:\2025\20252531 - Enclave at North Fontana\PRODUCT\Technical Studies\Noise\Noise Memo 11.5.25.docx» 8
To achieve Goal 3, the proposed project was assessed based on the requirements and noise
standards in the City’s Municipal Code, discussed below.
Municipal Code. Section 18-63(b)(7) of the City’s Municipal Code prohibits noises that are loud,
excessive, or impulsive and intrusive sound or noise that annoys or disturbs persons of ordinary
sensibilities from a distance of 50 feet or more from the edge of the property, structure, or unit in
which the source is located, are declared to be in violation, but such enumeration shall not be
deemed to be exclusive. Applicable noises that are prohibited under this section include the
following:
• Construction or Repairing of Buildings or Structures: The erection (including excavating),
demolition, alteration or repair of any building or structure other than 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 case of urgent necessity in the interest of public health and safety, and
then only with a permit from the building inspector, which permit may be granted for a
period not to exceed three days or less while the emergency continues and which permit
may be renewed for periods of three days or less while the emergency continues. If the
building inspector should determine that the public health and safety will not be impaired
by the erection, demolition, alteration or repair of any building or structure or the
excavation of streets and highways within the hours of 6:00 p.m. and 7:00 a.m., and if he
shall further determine that loss or inconvenience would result to any party in interest, he
may grant permission for such work to be done on weekdays within the hours of 6:00 p.m.
and 7:00 a.m., upon application being made at the time the permit for the work is awarded
or during the progress of the work.
Section 30-469 of the City’s Municipal Code (2025) has established daytime (7:00 a.m. to 10:00 p.m.)
and nighttime (10:00 p.m. to 7:00 a.m.) exterior noise standards of 65 dBA, for all zoning districts.
Section 30-470 of the City’s Municipal Code was used to evaluate potential vibration impacts from
project operations. This code states that no use shall create or cause to be created any activity that
causes a vibration that can be felt beyond the property line with or without the aid of an
instrument. Because the City does not specify the vibration level that can be felt, this analysis uses a
vibration perception threshold of 0.04 PPV (in/sec) from the Caltrans Manual (2020).
EXISTING SETTING
Overview of the Existing Noise Environment
Transportation facilities are the primary existing noise sources in the project area. Traffic noise in
the project area includes Curtis Avenue, Citrus Avenue, and other local roadways.

Ambient Noise Measurements
Long-Term Noise Measurements
Three long-term (24-hour) noise level measurements were conducted from August 28 to August 29,
2025, using Larson Davis Spark 706RC dosimeters to document the existing noise environment
within the project area. Table F summarizes the results of the long-term noise level measurements
along with a description of the measurement locations and noise sources that occurred during the
measurements. As shown in Table F, the calculated CNEL levels at LT-1, LT-2, and LT-3 were 58.2,
59.8, and 60.8 dBA, respectively. In addition, the daytime noise levels ranged from 46.4 to 60.0 dBA
Leq, and nighttime noise levels ranged from 48.9 to 55.6 dBA Leq. Also, the daytime maximum
instantaneous noise levels ranged from 61.7 to 80.0 dBA Lmax, and the nighttime maximum
instantaneous noise levels ranged from 58.6 to 77.5 dBA Lmax. The long-term noise level
measurement data sheets along with the hourly Leq and Lmax results are provided in Attachment C.

Existing Aircraft Noise
The closest public airport to the project site is Ontario International Airport, which is 9.1 miles
southwest of the project site. The Compatibility Policy Map: Noise Impact Zones from the
LA/Ontario International Airport Land Use Compatibility Plan (City of Ontario 2011) shows that the
project site is outside the 60 to 65 dBA CNEL noise contour. Also, there are no private airstrips
within 2 miles of the project site. Therefore, the project would not expose people working in the
project vicinity to aviation-related excessive noise levels, and this topic is not further discussed.

Existing Traffic Noise
The Federal Highway Administration (FHWA) Highway Traffic Noise Prediction Model (FHWA RD-77-
108) (FHWA 1977) was used to evaluate traffic-related noise conditions along roadways in the
project vicinity. This model requires various parameters, including traffic volumes, vehicle mix,
vehicle speed, and roadway geometry, to compute typical equivalent noise levels during daytime,
evening, and nighttime hours. The resulting noise levels are weighted and summed over 24-hour
periods to determine the CNEL values. The existing average daily traffic (ADT) volumes were derived
from The Enclave at North Fontana Residential Traffic Impact Analysis (Translutions, Inc. 2025). The
standard vehicle mix for Southern California roadways was used for roadways in the project vicinity.
Table G lists the existing traffic noise levels on roadways in the project vicinity. These noise levels
represent the worst-case scenario, which assumes that no shielding is provided between traffic and
the location where the noise contours are drawn. The specific assumptions used in developing these
noise levels and the model printouts are provided in Attachment D.

IMPACTS
Short-Term Construction Noise Impacts
Two types of short-term noise impacts could occur during construction on the project site. First,
construction crew commutes and the transport of construction equipment and materials to the site
for the proposed project would incrementally increase noise levels on roads leading to the site. The
pieces of heavy equipment for construction activities will be moved on site, will remain for the
duration of each construction phase, and will not add to the daily traffic volume in the project
vicinity. Although there would be a relatively high single-event noise exposure potential causing
intermittent noise nuisance (passing trucks at 50 feet would generate up to a maximum of 84 dBA),
the effect on longer-term (daily) ambient noise levels would be small because the daily
construction-related vehicle trips are small compared to the existing daily traffic volume on Curtis

Avenue and Citrus Avenue, which would be used to access the project site. The results of the
California Emissions Estimator Model (CalEEMod)(version 2022.1) contained in Attachment B of the
Air Quality, Energy, and Greenhouse Gas Technical Memorandum for the proposed Enclave at North
Fontana Project (LSA 2025) indicate that the combined building construction, paving, and
architectural coating phase would generate the most trips out of all of the construction phases due
to overlapping schedules and have an acoustical equivalent traffic volume of 290 and 266 passenger
car equivalent vehicles on Curtis Avenue and Citrus Avenue, respectively. Based on Table G, Curtis
Avenue and Citrus Avenue have estimated existing ADT volumes of 2,480 and 13,510, respectively,
near the project site. Based on the information above, construction-related traffic would increase
noise levels by up to 0.5 dBA. A noise level increase of less than 3 dBA would not be perceptible to
the human ear in an outdoor environment. Therefore, short-term construction-related noise
impacts associated with worker commute and equipment transport to the project site would be less
than significant. No mitigation measures are required.
The second type of short-term noise impact is related to noise generated from construction
activities. Construction is performed in discrete steps, each of which has its own mix of equipment
and, consequently, its own noise characteristics. The project anticipates site preparation, grading,
building construction, paving, and architectural coating phases of construction. These various
sequential phases change the character of the noise generated on a 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 H lists the Lmax recommended for noise
impact assessments for typical construction equipment included in the FHWA Highway Construction
Noise Handbook (FHWA 2006), based on a distance of 50 feet between the equipment and a noise
receptor.
Table I lists the anticipated construction equipment for each construction phase based on the
CalEEMod (Version 2022.1) results contained in Attachment B of the Air Quality, Energy, and
Greenhouse Gas Technical Memorandum for the proposed Enclave at North Fontana Project (LSA
2025). Table I shows the combined noise level at 50 feet from all of the equipment in each phase
and the Leq noise level for each equipment at 50 feet based on the quantity, reference Lmax noise
level at 50 feet, and the acoustical use factor. As shown in Table I, construction noise levels would
reach up to 89.2 dBA Leq at a distance of 50 feet.
Construction equipment is not situated at any one location during construction activities but is
typically spread throughout the residential development site at various distances from sensitive
receptors. Therefore, this analysis employs FTA guidance for calculating construction noise, which
recommends measuring construction noise produced by all construction equipment simultaneously
from the center of the residential development site. Table J shows the construction noise levels at the
closest residential property would reach up to 75.6 dBA Leq from the center of the project site.
Construction noise is temporary and would stop once project construction is completed. Compliance
with the City’s hours of construction pursuant to Section 18-63(b)(7) of the City’s Municipal Code
listed below would ensure construction-related noise would not be generated during the more
sensitive nighttime hours. Furthermore, construction-related noise levels would be below the FTA
noise level standard of 80 dBA Leq for residential uses. Therefore, construction noise impacts would be
less than significant. No mitigation measures are required.

Short-Term Construction Vibration Impacts
This construction vibration impact analysis discusses the level of human annoyance using vibration
levels in RMS amplitude and assesses the potential for building damage using vibration levels in PPV
(in/sec). Vibration levels calculated in RMS velocity are best for characterizing human response to
building vibration, whereas vibration levels in PPV are best for characterizing damage potential.

Table K shows the reference vibration levels at a distance of 25 feet for each type of standard
construction equipment from the Caltrans Manual (2020). Outdoor site preparation and grading for
the proposed project is expected to require the use of large bulldozers and loaded trucks, which
would generate ground-borne vibration of up to 0.089 in/sec PPV-max (0.062 in/sec PPV-RMS) and
0.076 in/sec PPV-max (0.053 in/sec PPV-RMS), respectively, when measured at 25 feet. Pile drivers,
vibratory rollers, and other heavy-tracked construction equipment would not be used during
construction of the proposed project.

The greatest vibration levels are anticipated during the site preparation and grading phases. All
other phases are expected to result in lower vibration levels. The distance to the nearest buildings
for vibration impact analysis is measured between the nearest off-site buildings and the project
boundary (assuming the construction equipment would be used at or near the project boundary)
because vibration impacts normally occur within the buildings.
The formula for vibration transmission is provided below:
PPVequip = PPVref x (25/D)1.1
Table L lists the projected vibration levels from various construction equipment expected to be used
on the project site in the active construction area to the nearest buildings in the project vicinity. As
shown in Table L, the closest residential building is approximately 335 feet from the center of the
project site and would experience a vibration level of up to 0.004 in/sec PPV-RMS. This vibration
level would not have the potential to result in community annoyance because vibration levels would
not exceed the Caltrans annoyance threshold of 0.04 in/sec PPV-RMS. Other building structures that
surround the project site would experience lower vibration levels because they are farther away.

Similarly, Table M lists the projected vibration levels from various construction equipment expected

project vicinity. As shown in Table M, the closest building is approximately 10 feet from the project
construction boundary and would experience a vibration level of up to 0.244 PPV (in/sec). This
vibration level would not have the potential to result in building damage because the building is
conservatively assumed to be an older residential structure or better, and the anticipated project-
related vibration levels would not exceed the Caltrans vibration damage threshold of 0.30 PPV
(in/sec). Other building structures that surround the project site would experience lower vibration
levels because they are farther away and are also conservatively assumed to be an older residential
structure or better, and the anticipated project-related vibration levels would not exceed the
Caltrans vibration damage threshold of 0.30 PPV (in/sec). Therefore, vibration levels generated from
project construction would be less than significant. No mitigation measures are required.

Long-Term Traffic Noise Impacts
The FHWA Highway Traffic Noise Prediction Model (FHWA RD-77-108) was used to evaluate traffic-
related noise conditions along roadways in the project vicinity. This model requires various
parameters, including traffic volumes, vehicle mix, vehicle speed, and roadway geometry, to
compute typical equivalent noise levels during daytime, evening, and nighttime hours. The resulting
noise levels are weighted and summed over 24-hour periods to determine the CNEL values. The
Existing, Opening Year (2026), and Future (2050) without and with project ADT volumes were
derived from The Enclave at North Fontana Residential Traffic Impact Analysis (Translutions, Inc.
2025). The standard vehicle mix for Southern California roadways was used for traffic on these
roadway segments. Tables N, O, and P list the traffic noise levels for the Existing, Opening Year
(2026), and Future (2050) without and with project scenarios, respectively. These noise levels
represent the worst-case scenario, which assumes that no shielding is provided between the traffic
and the location where the noise contours are drawn. The specific assumptions used in developing
these noise levels and the model printouts are provided in Attachment D.
Tables N, O, and P show that the project-related traffic would increase noise by up to 1.1 dBA. This
noise level increase is below 3 dBA and would not be perceptible to the human ear in an outdoor
environment. Therefore, traffic noise from project-related traffic on off-site sensitive receptors
would be less than significant. No noise mitigation measures are required.
Long-Term Stationary Noise Impacts
The proposed project includes on-site ground floor heating, ventilation, and air conditioning (HVAC)
units for the proposed residences, which could potentially operate 24 hours per day. The
specifications of typical HVAC equipment, including the reference noise level, are provided in
Attachment E. Each HVAC unit would generate a noise level of 44.4 dBA Leq at a distance of 50 feet.
Based on the site plan of the proposed project and surrounding land uses, it is estimated that
off-site residences would be exposed to up to four HVAC units from on-site residences, which would
generate a noise level of 50.4 dBA Leq at a distance of 50 feet. The closest residential property line is
approximately 10 feet from the four HVAC units and would be exposed to noise levels of 59.4 dBA
Leq (50.4 dBA + 14.0 dBA = 64.4 dBA). This noise level would be lower when factoring shielding from
the proposed residential building, existing 6 foot high wall, and/or proposed 6 foot high wall shown
in the project plans and would not exceed the City’s daytime and nighttime stationary noise
standard of 65 dBA. Therefore, noise impacts from project operations would be less than significant.
No mitigation measures are required.
Long-Term Ground-Borne Noise and Vibration from Vehicular Traffic
Once operational, the proposed project would not generate vibration. In addition, vibration levels
generated from project-related traffic on the adjacent roadways (i.e., Curtis Avenue and Citrus
Avenue) would be unusual for on-road vehicles because the rubber tires and suspension systems of
on road vehicles provide vibration isolation. Therefore, vibration levels generated from project-
related operations would be less than significant. No mitigation measures are required.

The RA14 is our 14 SEER air conditioner and is part of the
Rheem air conditioner product line that extends from 13 to 20
SEER. This highly featured and reliable air conditioner is
designed for years of reliable, efficient operation when matched
with Rheem indoor aluminum evaporator coils and furnaces or
air handler units with aluminum evaporators.
Our unique composite base () reduces sound emission, elimi-
nates rattles, significantly reduces fasteners, eliminates corro-
sion and has integrated brass compressor attachment inserts
(). Furthermore it has incorporated into the design, water
management features, means for hand placement () for unit
maneuvering, screw trays () and inserts for lifting off unit
pad. ()
Service Valves () are rigidly mounted in the composite base
with 3" between suction and discharge valves, 4" clearance
below service valves and a minimum of 5" above the service
valves, creating industry leading installation ease. The minimum
27 square-inches around the service valves allows ample room
to remove service valve schrader prior to brazing, plenty of clear-
ance for easy brazing of the suction and discharge lines to ser-
vice valve outlets, easy access and hookup of low loss refriger-
ant gauges (), and access to the service valve caps for
opening. For applications with long-line lengths up to 250 feet
total equivalent length, up to 200 feet condenser above evapora-
tor, or up to 80 feet evaporator above condenser, the long-line
instructions in the installation manual should be followed.
Controls are accessed from the corner of the unit by removing
only two fasteners from the control access cover, revealing the
industry’s largest 15" wide and 14" tall control area (). With all
this room in the control area the high voltage electrical whip ()
can easily be inserted through the right size opening in the bot-
tom of the control area. Routing it leads directly to contractor
lugs for connection. The low voltage control wires () are easily
connected to units low voltage wiring. If contactor or capacitor
() needs to be replaced there is more than adequate space to
make the repair. Furthermore, if high pressure and low pressure
model was not purchased but is desired to be installed in the
field, the service window () can be removed by removing two
screws, to access the high and low side schrader fittings for easy
field installation. The entire corner can be removed providing
ultimate access to install the high and low pressure switch. ()
If in the rare event, greater access is needed to internal compo-
nents, such as the compressor, the entire corner of the unit can
be removed along with the top cover assembly to have unprece-
dented access to interior of the unit (). Extra wire length is
incorporated into each outdoor fan and compressor so top
cover and control panel can be positioned next to the unit. With
minimal effort the plug can be removed from the compressor
and the outdoor fan wires can be removed from the capacitor to
allow even more uncluttered access to the interior of the unit ().
Outdoor coil heights range from as short as 22" to 32", aiding
access to the compressor. Disassembly to this degree and com-
plete reassembly only takes a first time service technician less
than 10 minutes. ()
All units utilize strong formed louver panels which provide indus-
try leading coil protection. Louver removal for coil cleaning is
accomplished by removing one screw and lifting the panel out of
the composite base pan. () All RA14 units utilize single row
coils () making cleaning easy and complete, restoring the
performance of the air conditioner back to out of the box perfor-
mance levels year after year.
The outdoor fan motor has sleeve bearings and is inherently
protected. The motor is totally enclosed for maximum protection
from weather, dust and corrosion. Access to the outdoor fan is
made by removing four fasteners from the fan grille. The outdoor
fan can be removed from the fan grille by removing 4 fasteners
in the rare case outdoor fan motor fails.
Each cabinet has optimized composite () fan orifice assuring
efficient and quiet airflow.

The entire cabinet has powder post paint () achieving 1000
hour salt spray rating, allowing the cabinet to retain its aesthetics
throughout its life.
Scroll compressors with standard internal pressure relief and
internal thermal overload are used on all capacities assuring
longevity of high efficient and quiet operation for the life of the
product.
Each unit is shipped with filter drier for field installation and will
trap any moisture or dirt that could contaminate the refrigerant
system.
All cabinets have industry leading structural strength due to the
composite base pan (), interlocking corner post (), formed
curved louver panels () and drawn top cover () making it
the most durable cabinet on the market today.
Each RA14 capacity has undergone rigorous psychometric test-
ing to assure performance ratings of capacity, SEER and EER
per AHRI Standard 210/240 rating conditions. Also
each unit bears the UL mark and each unit is certified
to UL 1995 safety standards.
Each unit has undergone specific strain and modal testing to
assure tubing () is outside the units natural frequency and that
the suction and discharge lines connected to the compressor
withstand any starting, steady state operation or shut down
forces imposed by the compressor.
All units have been sound tested in sound chamber to AHRI 270
rating conditions, and A-weighted Sound Power Level tables
produced, assuring units have acceptable noise qualities (see
page 9). Each unit has been ran in cooling operation at 95°F and
82°F and sound ratings for the RA14 range from as low as 74
dBA to 77 dBA.
All units have been ship tested to assure units meet stringent
“over the road” shipping conditions.
As manufactured all units in the RA14 family have cooling capa-
bility to 55 °F. Addition of low ambient control will allow the unit
to operate down to 0°F. Factory testing is performed on each
unit. All component parts meet well defined specification and
continually go through receiving inspections. Each component
installed on a unit is scanned, assuring correct component uti-
lization for a given unit capacity and voltage. All condenser coils
are leak tested with pressurization test to 550#’s and once
installed and assembled, each units’ complete refrigerant
system is helium leak tested. All units are fully charged from the
factory for up to 15 feet of piping. All units are factory run tested.
The RA14 has a 10-year conditional compressor and parts war-
ranty (registration required).
