1 Project Description and Impact Summary
1.1 Introduction
This study analyzes the potential noise and vibration impacts of the proposed Ventana at Duncan
Canyon Specific Plan Amendment (herein referred to as “project” or “Specific Plan Amendment”) in
Fontana, California. Rincon Consultants, Inc. (Rincon) prepared this study under contract to City of
Fontana. The purpose of this study is to analyze the project’s noise and vibration impacts related to
both temporary construction activity and long-term operation of the project. Table 1 provides a
summary of project impacts. This technical study was prepared in support of a Supplemental
Environmental Impact Report (EIR) for the Ventana at Duncan Canyon Specific Plan, analyzed in a
previous Final EIR (State Clearinghouse Number 2005111048) that was approved by the City of
Fontana on March 27, 2007.

NOI-1 Construction Noise Best Management Practices
The project applicant shall reduce construction noise levels at the adjacent single- and multi-family
uses to the south of the project site, through measures such as, but not limited to:
▪ All construction equipment shall be equipped with noise-reduction devices such as mufflers to
minimize construction noise and all internal combustion engines shall be equipped with exhaust
and intake silencers in accordance with manufacturers’ specifications.
City of Fontana
Ventana at Duncan Canyon Specific Plan Amendment

▪ Equipment that is quieter than standard equipment shall be used, including electrically powered
equipment instead of internal combustion equipment where use of such equipment is a readily
available.
▪ The use of bells, whistles, alarms, and horns shall be restricted to safety warning purposes only.
▪ Construction areas for staging and warming up shall be located as far as possible from adjacent
residential buildings and sensitive receptors.
NOI-2 Exterior-to-Interior Noise Analysis
For residential units where exterior noise levels exceed 70 dBA CNEL, the project applicant shall
coordinate with the project architects and other contractors to ensure compliance with the 45 dBA
CNEL interior noise level standard. This shall be achieved through additional exterior-to-interior
noise analysis and incorporation of noise attenuation features once specific building plan
information is available. The information in the analysis shall include wall heights and lengths, room
volumes, window and door tables typical for a building plan, as well as information on other
openings in the building shell. With this specific building plan information, the analysis shall
determine the predicted interior noise levels at the planned on-site buildings. If predicted noise
levels are found to be in excess of the applicable limit, the report shall identify architectural
materials or techniques that could be included to reduce noise levels to the applicable limit. The
project applicant shall comply with mitigation measures included in the interior noise report to
reduce interior noise levels where applicable noise limits are exceeded.
1.2 Project Summary
Project Location
The 102-acre Specific Plan area is east of Interstate 15 (I-15), west of Citrus Avenue, and both north
and south of Duncan Canyon Road in the northern part of the City of Fontana, within San
Bernardino County, California. The Specific Plan area is bound by I-15 to the north and west, Citrus
Avenue to the east, and a Southern California Edison (SCE) transmission line corridor to the south.
Figure 1 shows the project site’s regional location and Figure 2 shows the Specific Plan area in its
vicinity context.
Regional access is available from the west via I-15. Regional access is also provided by nearby
Interstate 210 (I-210), Interstate 10 (I-10), and Interstate 215 (I-215). Direct access is provided by
Duncan Canyon Road, which bisects the project area to the west/east and Citrus Avenue, which
provides north/south access. Citrus Avenue currently terminates to the north at the intersection of
Duncan Canyon Road, while Duncan Canyon Road terminates to the east of Citrus Avenue.

Project Background
The existing Duncan Canyon at Ventana Specific Plan (2007 Specific Plan) was established in March
2007 to create a unique master planned development that captured the City’s vision for the
“Regional Mixed Use” zoning classification in northern Fontana, and the City’s vision for a Corporate
Corridor along I-15. Ten distinct development areas, designated as “Planning Areas,” were
established to implement the goals and objectives of the 2007 Specific Plan.
The ten Planning Areas consisted of four types of land use designations including Commercial,
Mixed Use, Medium Density Residential, and Medium-High Density Residential. The project included
the development of up to 574,500 square feet of commercial uses; 842 dwelling units in three
separate residential villages; a Corporate Office Corridor, including mid-rise office buildings, a
multi-story hotel, quality business restaurants; a focal point “Piazza;” a ““campanile” tower feature;
pedestrian corridors and bridges; and the construction of the realigned Lytle Creek Road on a
105-acre project site.
Project Description
The project includes a comprehensive Specific Plan Amendment to the 2007 Specific Plan. Six
Planning Areas are proposed, instead of ten as previously analyzed, involving the following land
uses: medium density residential, medium-high density residential, mixed-use entertainment,
commercial uses, and open space. Planning Areas 5 and 6 are both split into A and B sub-parcels
(i.e., 5a, 5b, 6a, and 6b). The Specific Plan Amendment would allow for development of 1,671 mid-
rise multi-family dwelling units and 476,500 square feet of commercial use in phases by Planning
Area, summarized in Table 2. There would be six phases with construction of certain Planning Areas
overlapping. Accounting for the construction overlap, there would be four unique phases.
Additionally, Duncan Canyon Road and Citrus Avenue (arterial roadways) and Lytle Creek Road
(backbone road) would be developed during Phase 1. The arterial roadways are approximately
7.3-acres and the backbone roads are approximately 10.5-acres for a total of 17.8-acres of roadway.
See Figure 3 for the land use Planning Areas for the Specific Plan Amendment.
Planning Areas 1 and 3 would be developed first between the years 2022 to late 2023. The first
phase would consist of 538 mid-rise dwelling units in Planning Area 1, which is approximately
20.7-acres located in the northeastern corner of the plan area. In Planning Area 3, 154,000 square
feet of commercial retail use and 26,000 square feet of medical-dental office use would be
constructed over 9.7-acres along the plan area’s northwestern edge. The arterial and backbone
roads would also be constructed during this phase to provide development flexibility for all planning
areas.
Phase 2 would occur from late 2023 to early 2025 with development occurring only in Planning
Area 2. The 13.2-acre parcel is located in the southeastern corner of the site south of Duncan
Canyon Road and west of Citrus Avenue. Under Phase 2, 396 mid-rise dwelling units would be
constructed.
The third phase of development would include Planning Areas 4, 5a, and 5b. Construction is
anticipated to occur from 2025 to 2028. Planning Area 4 is approximately 24 acres and located on
the outer western edge below Duncan Canyon Road. Land uses proposed in this area include
600 mid-rise dwelling units, 26,000 square feet of commercial retail use, a 31,200 square foot
supermarket, a 20,800 square foot pharmacy with a drive-thru, and 26,000 square feet of high-
turnover sit-down restaurant use. In Planning Areas 5a and 5b, the same land uses are proposed
City of Fontana
Ventana at Duncan Canyon Specific Plan Amendment
6
with both parcels totaling 46,250 square feet of commercial retail use, 10,853 square feet of high-
turnover site down restaurant, and 15,417 square feet for a fast-food restaurant.
Phase four would be the final phase and it would include the development of Planning Areas 6a and
6b. Approximately 137 dwelling units and 74,000 square feet of medical-dental offices would be
constructed in Planning Area 6a, while in Planning Area 6b only 26,000 square feet of commercial
retail would be constructed. During this phase, 0.5 acres of open space would also be developed.
These planning areas total 8.2-acres and are in the southeastern corner of the Specific Plan area.
Construction
Construction is assumed to begin January 2022 and is estimated to be completed in 2030 for a total
construction period of approximately nine years. Construction activities would include site
preparation, grading, building construction, paving, and architectural coating (i.e., painting). There
would be no demolition phase since the site is vacant. Each Planning Area was assumed to be
graded during its respective construction phase with no mass grading of the entire site. The total
earthwork for the plan area is 150,000 cubic yards with each planning area being balanced on-site.
All construction would occur within the current conceptual limits of the project.
Operation
Planning Areas 1 and 3 would be operational in 2023. The remainder of the plan area would be fully
built-out and operational by the year 2030.

Ventana at Duncan Canyon Specific Plan Final Environmental Impact Report
Noise Mitigation
The Ventana at Duncan Canyon Specific Plan 2007 Final Environmental Impact Report (2007 EIR)
determined the following noise mitigation measures would be required:
▪ Measure 4.6.1: During construction, the following measures shall be implemented to
reduce noise on sensitive receptors:
□ All off-road construction equipment shall have properly operated and maintained
mufflers.
□ Stockpiling and equipment/vehicle staging shall be conducted as far as practicable from
occupied dwelling units or other nearby noise-sensitive land uses.
□ Idling of construction equipment shall be limited to the extent feasible. Equipment shall
be turned off when not in use.
□ Schedule noisy activities and impulsive noise generation such as pile driving or jack-
hammers during the late morning and early afternoon hours, or erect temporary
barriers, if necessary.
▪ Mitigation Measure 4.6.2: Homes in Planning Area 5 backing up to the I-15 Freeway shall be
required to site outdoor recreational uses on the opposite side of the buildings, allowing the
buildings to act as a sound wall. An 8-foot sound wall shall also be constructed at the edge
of the Freeway right-of-way. If this cannot be accomplished, setbacks, obstructions to the
noise path, or a 28-foot sound wall would be required to mitigate exterior noise to 65 dBA
CNEL.
▪ Mitigation Measure 4.6.3: Homes along Duncan Canyon Road shall be constructed with
dual-paned windows and supplemental ventilation to allow for 1 dBA CNEL attenuation to
meet the City of Fontana’s 45 dBA CNEL interior noise standard.
▪ Mitigation Measure 4.6.4: Homes in Planning Area 5 backing up to the I-15 Freeway shall be
constructed with upgraded structural acoustical features to allow for up to 35 dBA CNEL
attenuation to meet the City of Fontana’s 45 dBA CNEL interior noise standard. Dual-paned
windows and supplemental ventilation and highly upgraded structural features shall be
provided for homes closest to the freeway. A supplemental acoustical analysis shall be
submitted in conjunction with the issuance of building permits to verify that adequate
structural noise protection will be provided.
▪ Mitigation Measure 4.6.5: Conditional use permits for commercial uses shall contain
measures that control noise generation from goods deliveries, facility maintenance, and
mechanical equipment. These may include:
□ Location of commercial HVAC equipment away from residences or shielding of HVAC
equipment
□ Location of loading docks away from residences
□ Time restrictions on deliveries to commercial uses
□ Orientation of fast-food restaurant sound boards away from nearby residences; sound
walls around the order boards; or time restrictions on sound board use

□ Time restrictions on refuse collection or parking lot sweeping, or stacking or retrieval of
temporary outdoor storage
□ Location of the hotel’s pool and outdoor entertainment areas on the opposite side of
the hotel from the closest residential uses or construction of a sound wall
Background
Noise and Vibration Study 11
2 Background
2.1 Overview of Sound Measurement
Sound is a vibratory disturbance created by a moving or vibrating source, which is capable of being
detected by the hearing organs. Noise is defined as sound that is loud, unpleasant, unexpected, or
undesired and may therefore be classified as a more specific group of sounds. The effects of noise
on people can include general annoyance, interference with speech communication, sleep
disturbance, and, in the extreme, hearing impairment (California Department of Transportation
[Caltrans] 2013).
Noise levels are commonly measured in decibels (dB) using the A-weighted sound pressure level
(dBA). The A-weighting scale is an adjustment to the actual sound pressure levels so that they are
consistent with the human hearing response, which is most sensitive to frequencies around
4,000 Hertz and less sensitive to frequencies around and below 100 Hertz (Kinsler, et. al. 1999).
Decibels are measured on a logarithmic scale that quantifies sound intensity in a manner similar to
the Richter scale used to measure earthquake magnitudes. A doubling of the energy of a noise
source, such as doubling of traffic volume, would increase the noise level by 3 dBA; reducing the
energy in half would result in a 3 dBA decrease (Crocker 2007).
Human perception of noise has no simple correlation with sound energy: the perception of sound is
not linear in terms of dBA or in terms of sound energy. Two sources do not “sound twice as loud” as
one source. It is widely accepted that the average healthy ear can barely perceive changes of 3 dBA,
increase or decrease (i.e., twice the sound energy); that a change of 5 dBA is readily perceptible
(8 times the sound energy); and that an increase (or decrease) of 10 dBA sounds twice (half) as loud
([10.5x the sound energy] Crocker 2007).
Sound changes in both level and frequency spectrum as it travels from the source to the receiver.
The most obvious change is the decrease in level as the distance from the source increases. The
manner in which noise reduces with distance depends on factors such as the type of sources (e.g.,
point or line, the path the sound will travel, site conditions, and obstructions). Noise levels from a
point source typically attenuate, or drop off, at a rate of 6 dBA per doubling of distance (e.g.,
construction, industrial machinery, ventilation units). Noise from a line source (e.g., roadway,
pipeline, railroad) typically attenuates at about 3 dBA per doubling of distance (Caltrans 2013). The
propagation of noise is also affected by the intervening ground, known as ground absorption. A hard
site, such as a parking lot or smooth body of water, receives no additional ground attenuation and
the changes in noise levels with distance (drop-off rate) result from simply the geometric spreading
of the source. An additional ground attenuation value of 1.5 dBA per doubling of distance applies to
a soft site (e.g., soft dirt, grass, or scattered bushes and trees) (Caltrans 2013). Noise levels may also
be reduced by intervening structures. The amount of attenuation provided by this “shielding”
depends on the size of the object and the frequencies of the noise levels. Natural terrain features
such as hills and dense woods, and man-made features such as buildings and walls, can substantially
alter noise levels. Generally, any large structure blocking the line of sight will provide at least a
5-dBA reduction in source noise levels at the receiver (Federal Highway Administration [FHWA]
2011). Structures can substantially reduce exposure to noise as well. The FHWA’s guidelines indicate
that modern building construction generally provides an exterior-to-interior noise level reduction of
20 to 35 dBA with closed windows.

The impact of noise is not a function of loudness alone. The time of day when noise occurs and the
duration of the noise are also important factors of project noise impact. Most noise that lasts for
more than a few seconds is variable in its intensity. Consequently, a variety of noise descriptors
have been developed. One of the most frequently used noise metrics is the equivalent noise level
(Leq); it considers both duration and sound power level. Leq is defined as the single steady
A-weighted level equivalent to the same amount of energy as that contained in the actual
fluctuating levels over time. Typically, Leq is summed over a one-hour period. Lmax is the highest root
mean squared (RMS) sound pressure level within the sampling period, and Lmin is the lowest RMS
sound pressure level within the measuring period (Crocker 2007).
Noise that occurs at night tends to be more disturbing than that occurring during the day.
Community noise is usually measured using Day-Night Average Level (Ldn), which is the 24-hour
average noise level with a +10 dBA penalty for noise occurring during nighttime (10:00 p.m. to
7:00 a.m.) hours; it is also measured using Community Noise Equivalent Level (CNEL), which is the
24-hour average noise level with a +5 dBA penalty for noise occurring from 7:00 p.m. to 10:00 p.m.
and a +10 dBA penalty for noise occurring from 10:00 p.m. to 7:00 a.m. (Caltrans 2013). Noise levels
described by Ldn and CNEL usually differ by about 1 dBA or less. The relationship between the peak-
hour Leq value and the Ldn/CNEL depends on the distribution of traffic during the day, evening, and
night. Quiet suburban areas typically have CNEL noise levels in the range of 40 to 50 dBA, while
areas near arterial streets are in the 50 to 60-plus CNEL range. Normal conversational levels are in
the 60 to 65-dBA Leq range; ambient noise levels greater than 65 dBA Leq can interrupt conversations
(Federal Transit Administration [FTA] 2018).
2.2 Vibration
Groundborne vibration of concern in environmental analysis consists of the oscillatory waves that
move from a source through the ground to adjacent structures. The number of cycles per second of
oscillation makes up the vibration frequency, described in terms of Hz. The frequency of a vibrating
object describes how rapidly it oscillates. The normal frequency range of most groundborne
vibration that can be felt by the human body starts from a low frequency of less than 1 Hz and goes
to a high of about 200 Hz (Crocker 2007).
While people have varying sensitivities to vibrations at different frequencies, in general they are
most sensitive to low-frequency vibration. Vibration in buildings, such as from nearby construction
activities, may cause windows, items on shelves, and pictures on walls to rattle. Vibration of building
components can also take the form of an audible low-frequency rumbling noise, referred to as
groundborne noise. Groundborne noise is usually only a problem when the originating vibration
spectrum is dominated by frequencies in the upper end of the range (60 to 200 Hz), or when
foundations or utilities, such as sewer and water pipes, physically connect the structure and the
vibration source (FTA 2018). Although groundborne vibration is sometimes noticeable in outdoor
environments, it is almost never annoying to people who are outdoors. The primary concern from
vibration is that it can be intrusive and annoying to building occupants and vibration-sensitive land
uses.
Vibration energy spreads out as it travels through the ground, causing the vibration level to diminish
with distance away from the source. High-frequency vibrations diminish much more rapidly than
low frequencies, so low frequencies tend to dominate the spectrum at large distances from the
source. Discontinuities in the soil strata can also cause diffractions or channeling effects that affect
the propagation of vibration over long distances (Caltrans 2020). When a building is affected by
Background
Noise and Vibration Study 13
vibration, a ground-to-foundation coupling loss will usually reduce the overall vibration level.
However, under rare circumstances, the ground-to-foundation coupling may actually amplify the
vibration level due to structural resonances of the floors and walls.
Vibration amplitudes are usually expressed in peak particle velocity (PPV) or RMS vibration velocity.
The PPV and RMS velocity are normally described in inches per second. PPV is defined as the
maximum instantaneous positive or negative peak of a vibration signal. PPV is often used in
monitoring of blasting vibration because it is related to the stresses that are experienced by
buildings (Caltrans 2020).
2.3 Sensitive Receivers
Noise exposure goals for various types of land uses reflect the varying noise sensitivities associated
with those uses. Sensitive land uses are generally defined as locations where people reside or where
the presence of noise could adversely affect the use of the land. The City of Fontana General Plan
list of noise sensitive uses includes residential uses; hospitals; rest homes; long term care facilities;
mental care facilities; schools; libraries; places of worship; and passive recreation uses (City of
Fontana 2018). Sensitive receivers in the area include the single-family residences located across
Citrus Avenue (Lennar at Arboretum) to the east of the project site and single-family residential
developments approximately 500 feet (Laurel Oak at Shady Trails) and approximately 800 feet
(Shady Trails Community) to the south of the project site.
Vibration sensitive receivers are similar to noise sensitive receivers, such as residences and
institutional uses (e.g., schools, libraries, and religious facilities). The General Plan does not identify
vibration sensitive receivers; however, concert halls, hospitals, libraries, research operations,
residential areas, schools, and offices would also be considered vibration sensitive uses. Vibration
sensitive receivers also include buildings where vibrations may interfere with vibration-sensitive
equipment, affected by levels that may be well below those associated with human annoyance
(FTA 2018; Caltrans 2013).
2.4 Project Noise Setting
The most common source of noise in the project site vicinity is vehicular traffic from I-15, Duncan
Canyon Road, and Citrus Avenue. Aircraft over-flights are also audible on the project site.
Construction was active during noise measurements across Citrus Avenue and along Lytle Creek
Road adjacent to the project site. To characterize ambient sound levels at and near the project site,
three short-term 15-minute noise level measurements were conducted on May 26, 2021. Noise
Measurement (NM) 1 was conducted at the southeastern portion of the project site to capture
noise levels from Citrus Avenue. NM2 was conducted at the central portion of the project site to
capture ambient noise levels from Duncan Canyon Road. NM3 was conducted in the north central
portion of the project site to capture noise levels from I-15 at project noise sensitive receivers. Table
3 summarizes the results of the noise measurement, Table 4 shows the recorded traffic volumes
during noise measurements, and Figure 4 shows the measurement locations.

Federal
FTA Transit and Noise Vibration Impact Assessment Manual
The FTA provides reasonable criteria for assessing construction noise impacts based on the potential
for adverse community reaction in their Transit and Noise Vibration Impact Assessment Manual
(FTA 2018). For residential, commercial, and industrial uses, the daytime noise threshold is 80 dBA

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 each county and city to adopt a General Plan that includes a Noise
Element prepared per guidelines adopted by the Governor’s Office of Planning and Research. The
purpose of the Noise Element is to limit the exposure of the community to excessive noise levels.
The California Environmental Quality Act (CEQA) requires all known environmental effects of a
project be analyzed, including environmental noise impacts.

California Noise Control Act of 1973
California Health and Safety Code Sections 46000 through 46080, known as the California Noise
Control Act, find that excessive noise is a serious hazard to public health and welfare and that
exposure to certain levels of noise can result in physiological, psychological, and economic damage.
The act also finds that there is a continuous and increasing bombardment of noise in urban,
suburban, and rural areas. The California Noise Control Act declares that the State of California has a
responsibility to protect the health and welfare of its citizens by the control, prevention, and
abatement of noise. It is the policy of the State to provide an environment for all Californians that is
free from noise that jeopardizes their health or welfare.
California Building Code
CCR Title 24, Building Standards Administrative Code, Part 2, and the California Building Code codify
the state noise insulation standards. These noise standards apply to new construction in California
to control interior noise levels as they are affected by exterior noise sources. The regulations specify
that interior noise levels for residential and school land uses should not exceed 45 dBA CNEL.

City of Fontana Municipal Code
Chapter 18, Article II (Noise) and Chapter 30 Articles V (Residential Zoning Districts) and VII
(Industrial Zoning Districts) of the Fontana Municipal Code seeks to control unnecessary, excessive,
and annoying noise and vibration. The following sections would be applicable to the proposed
project:
▪ Section 18-63(b)(6), Loading, unloading or opening boxes. The creation of a loud, excessive,
impulsive or intrusive and excessive noise in connection with loading or unloading of any vehicle
or the opening and destruction of bales, boxes, crates and containers within 50 feet or more
from the edge of the property.
▪ 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. Project
construction noise levels are, therefore, considered exempt from municipal regulation if
City of Fontana

Methodology
Noise and Vibration Study 19
3 Methodology
3.1 Construction Noise
Construction noise was estimated using the FHWA Roadway Construction Noise Model (RCNM)
(FHWA 2006). RCNM predicts construction noise levels for a variety of construction operations
based on empirical data and the application of acoustical propagation formulas. Using RCNM,
construction noise levels were estimated at noise sensitive receivers near the project site. RCNM
provides reference noise levels for standard construction equipment, with an attenuation rate of
6 dBA per doubling of distance for stationary equipment.
Variation in power imposes additional complexity in characterizing the noise source level from
construction equipment. Power variation is accounted for by describing the noise at a reference
distance from the equipment operating at full power and adjusting it based on the duty cycle of the
activity to determine the Leq of the operation (FHWA 2006). Each phase of construction has a
specific equipment mix, depending on the work to be accomplished during that phase. Each phase
also has its own noise characteristics; some will have higher continuous noise levels than others,
and some have high-impact noise levels.
Construction activity would result in temporary noise in the project site vicinity, exposing
surrounding nearby receivers to increased noise levels. Construction noise would typically be higher
during the heavier periods of initial construction (i.e., site preparation and grading) and would be
lower during the later construction phases (i.e., building construction and paving). Typical heavy
construction equipment during project grading could include dozers, loaders, graders, and dump
trucks. It is assumed that diesel engines would power all construction equipment. Construction
equipment would not all operate at the same time or location. In addition, construction equipment
would not be in constant use during the 8-hour operating day.
Project construction would occur nearest to single-family residences to the east (Arboretum Specific
Plan) and south (Citrus Heights North Specific Plan) of the project site. Over the course of a typical
construction day, construction equipment would be located as close as 300 feet and 400 feet to
properties east and south, respectively, but would typically be located at an average distance
farther away due to the nature of construction and the size of the project. Therefore, it is assumed
that over the course of a typical construction day the construction equipment would operate at an
average distance 350 feet from the single-family residences to the east and 450 feet from single
family residences to the south of the project site.
Construction noise is typically loudest during activities that involve excavation and move soil, such
as site preparation and grading. A potential high-intensity construction scenario includes a grader,
loader, dozer, and dump truck working during grading to excavate and move soil. At a distance of
350 feet and 450 feet, a grader, a front-end loader, a dozer, and a dump truck would generate a
noise level of 64 dBA Leq and 62 dBA Leq, respectively (RCNM calculations are included in
Appendix B).
3.2 Groundborne Vibration
The project does not include any substantial vibration sources associated with operation. Therefore,
construction activities have the greatest potential to generate groundborne vibration affecting
City of Fontana
Ventana at Duncan Canyon Specific Plan Amendment
20
nearby receivers, especially during grading and excavation of the project site. The greatest vibratory
source during construction within the project vicinity would be a vibratory roller. Neither blasting
nor pile driving would be required for construction of the project. Construction vibration estimates
are based on vibration levels reported by Caltrans and the FTA (Caltrans 2020, FTA 2018). Table 6
shows typical vibration levels for various pieces of construction equipment used in the assessment
of construction vibration (FTA 2018).

Equipment PPV at 25 ft. (in./sec.)
Large Bulldozer 0.089
Loaded Trucks 0.076
Small Bulldozer 0.003
Source: FTA 2018
Vibration limits used in this analysis to determine a potential impact to local land uses from
construction activities, such as blasting, pile-driving, vibratory compaction, demolition, drilling, or
excavation, are based on information contained in Caltrans’ Transportation and Construction
Vibration Guidance Manual and the Federal Transit Administration and the FTA Transit Noise and
Vibration Impact Assessment Manual (Caltrans 2020; FTA 2018). Maximum recommended vibration
limits by the American Association of State Highway and Transportation Officials (AASHTO) are
identified in Table 7.
Table 7 AASHTO Maximum Vibration Levels for Preventing Damage
Type of Situation Limiting Velocity (in./sec.)
Historic sites or other critical locations 0.1
Residential buildings, plastered walls 0.2–0.3
Residential buildings in good repair with gypsum board walls 0.4–0.5
Engineered structures, without plaster 1.0–1.5
Source: Caltrans 2020
Based on AASHTO recommendations, limiting vibration levels to below 0.2 in./sec. PPV at residential
structures would prevent structural damage regardless of building construction type. These limits
are applicable regardless of the frequency of the source. However, as shown in Table 8 and Table 9,
potential human annoyance associated with vibration is usually different if it is generated by a
steady state or a transient vibration source.
Table 8 Human Response to Steady State Vibration
PPV (in./sec.) Human Response
3.6 (at 2 Hz)–0.4 (at 20 Hz) Very disturbing
0.7 (at 2 Hz)–0.17 (at 20 Hz) Disturbing

0.012 Slightly perceptible

PPV (in./sec.) Human Response
2.0 Severe
0.9 Strongly perceptible
0.24 Distinctly perceptible
0.035 Barely perceptible
Source: Caltrans 2020
As shown in Table 9, the vibration level threshold at which transient vibration sources (such as
construction equipment) are considered to be distinctly perceptible is 0.24 in./sec. PPV. This analysis
uses the distinctly perceptible threshold for purposes of assessing vibration impacts.
Although groundborne vibration is sometimes noticeable in outdoor environments, it is almost
never annoying to people who are outdoors; therefore, the vibration level threshold is assessed at
occupied structures (FTA 2018). Therefore, all vibration impacts are assessed at the structure of an
affected property.
3.3 Operational Noise Sources
On-site noise source would include general conversations, landscape maintenance, waste hauling,
loading dock, parking lot, and the heating, ventilation, and air conditioning (HVAC) equipment.
There are no large gathering areas on the project site and these sources would be transient in
nature as people transit from vehicles to the stores or restaurants. Therefore, general conversations
would not represent a substantial noise source. Landscape maintenance and waste hauling typically
occur during the less noise sensitive daytime hours and would be active for short periods of time.
Heating, Ventilation, and Air Conditioning Units
Noise-generating mechanical equipment on building rooftops include HVAC units. The equipment
was assumed to be placed on the approximate center of the rooftop; noise levels for the equipment
are described below. This analysis conservatively assumes the equipment would operate
continuously for a full hour (100 percent for 60 minutes) during the daytime and nighttime. For a
conservative assessment, it has been assumed that the equipment would not include any type of
screening. Noise propagation was estimated in SoundPLAN using algorithms from ISO
Standard 9613-2, “Attenuation of Sound during Propagation Outdoors, Part 2: General Method of
Calculation.”
Based upon one ton of HVAC per 600 square feet of building space and the square footage of each
proposed building shown on the conceptual site plan, 10-ton Trane T/YHC120E HVAC units of 87 dB
were selected for analysis (see Appendix C for manufacturer’s specifications). Table 10 shows the
noise spectrum data and Table 11 shows the square footage and number of HVAC units applied to
each building modeled. Figure 5 shows the conceptual site plan with corresponding building labels.

3.4 Traffic Noise
Noise affecting the project site is primarily from traffic on I-15, Duncan Canyon Road, and Citrus
Avenue. Future noise levels affecting the compatibility of the project site were estimated in
SoundPLAN using algorithms and reference traffic noise reference levels from the FHWA’s Traffic
Noise Model (TNM). The off-site traffic noise increases were modeled with the FHWA RD-77-108
Traffic Noise Prediction Model.
The traffic vehicle classification mix for I-15 was based on Caltrans Truck Counts (Caltrans 2016). I-5
was modeled with a vehicle classification mix of 94.4 percent automobiles, 2.5 percent medium
trucks, and 3.1 percent heavy trucks and a posted speed limit of 65 miles per hour (mph).
Future traffic volumes on local roadways were obtained from the Ventana Specific Plan Amendment
Traffic Study (Urban Crossroads 2021). Traffic volumes were input into the model as shown in Table
12. The posted speed limits on Duncan Canyon Road, Citrus Avenue, Casa Grande, Summit Avenue,
Sierra Avenue and Lytle Creek Drive are 45 mph, 40 to 45 mph, 35 mph,45 to 50 mph, 55 mph, and
35 mph, respectively. Traffic counts conducted during noise monitoring consisted of primarily active
construction traffic vehicles and are not considered representative of typical vehicle classification
mix for Specific Plan area roadways. Therefore, the vehicle classification mix for modeling assumes a
typical breakdown of 96 percent automobiles, 2.5 percent medium trucks, and 1.5 percent heavy
trucks for local roadways.
Traffic distribution through the day was modeled assuming 75 percent of total daily vehicle traffic
during daytime hours, 15 percent of daily vehicle traffic during evening hours, and 10 percent of
daily vehicle traffic during nighttime hours. For determining noise-land use compatibility, exterior
traffic noise levels at the residential exterior common use areas (pool areas) and residential building
façades were calculated. Receivers were placed on the ground floor at 5 feet above ground level;
receivers at 2nd and 3rd stories were placed 15 and 25 feet above ground level.

3.5 Significance Thresholds
The following thresholds are based on City of Fontana noise standards and Appendix G of the CEQA
Guidelines. Noise impacts would be considered significant if:
▪ Item 1. The project would result in the 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.
Based on the Fontana Municipal Code Section 18-63(b)(7) and FTA construction noise
standards, construction noise would be significant if:
− Construction and demolition work are conducted between the hours of 6:00 p.m. and
7:00 a.m. on weekdays and between the hours of 5:00 p.m. to 8:00 a.m. on Saturdays.
− Noise levels exceed the FTA daytime criteria of 80 dBA Leq, 85 dBA Leq, and 90 dBA Leq for
an 8-hour period for residential, commercial, and industrial land uses, respectively.
Based on the Fontana Municipal Code Section 30-469, operational noise would be
significant if:
− Noise levels exceed 45 dBA at interior areas and 65 dBA at exterior areas.
Traffic-related noise impacts would be considered significant if project-generated traffic
would result in exposure of sensitive receivers to an unacceptable increase in noise levels.
− For purposes of this analysis, a significant impact would occur if project-related traffic
increases the ambient noise environment of noise-sensitive land uses by 3 dBA or more
if the locations are subject to noise levels in excess of conditionally compatible levels, or
by 5 dBA or more if the locations are not subject to noise levels in excess of the
conditionally compatible levels identified in the City of Fontana General Plan.
▪ Item 2. The project would result in the generation of excessive groundborne vibration or
groundborne noise levels.
Vibration levels equal to or below 0.4 in./sec. PPV at residential structures would prevent
structural damage for most residential building and vibration levels equal to or less than
1.0 in./sec. PPV would prevent damage to more substantial construction, such as high-rise,
commercial, and industrial buildings. For human annoyance, the vibration level threshold at
which transient, or temporary, vibration sources are considered to be distinctly perceptible
is 0.24 in./sec. PPV.
▪ Item 3. 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, if the project exposes people residing or working in the project area to excessive noise
levels.

4 Impact Analysis
4.1 Item 1 – Temporary and Permanent Noise Increase
Item: Would the project 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? (Less Than
Significant Impact with Mitigation)
Construction
As described in Section 3.1, at a distance of 350 feet and 450 feet, a grader, a front-end loader, a
dozer, and a dump truck would generate a noise level of 64 dBA Leq and 62 dBA Leq, respectively. The
entire project would not be constructed all at once but built out in six phases. Actual buildout would
be subject to market and economic conditions, jurisdictional processing of approvals, and
infrastructure timing, and may vary from the construction phasing currently anticipated. As the
project Planning Areas are developed, residential uses in Planning Areas 1-A, 1-B, 3, and 4 may be
exposed to other Planning Area construction noise. Table 13 shows the combined hourly and
maximum construction noise levels attributable to construction of each Planning Area modeled,
noise sensitive receivers analyzed, and resulting exterior and interior noise levels.

See Appendix B for RCNM results.
As shown in Table 13, Planning Area construction exterior hourly noise levels would range from
62 dBA Leq to 75 dBA Leq at the nearest noise sensitive receivers, with maximum noise levels ranging
from 63 dBA Lmax to 76 dBA Lmax (see Appendix B for construction noise modeling results). Planning
Area construction interior hourly noise levels would range from 37 dBA Leq to 50 dBA Leq at the
Impact Analysis
Noise and Vibration Study 29
nearest noise sensitive receivers, with maximum noise levels ranging from 38 dBA Lmax to 51 dBA
Lmax. The FTA’s daytime construction noise limit is 80 dBA Leq for residential uses; therefore, project
construction noise levels would not exceed construction noise thresholds. In addition, construction
activities would be restricted to daytime hours per 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, avoiding noise sensitive nighttime hours where interior noise levels could be considered
an impact. Therefore, construction noise impacts would be less than significant.
However, the timing of construction would be market dependent and the potential exists for
construction noise to expose built out noise sensitive receivers in Planning Areas to subsequent
Planning Area construction noise. Therefore, the following recommendation should be taken into
consideration to benefit occupied on-site dwelling units.
Recommendation
The following recommendation would reduce construction noise levels at on-site noise sensitive
uses adjacent to Planning Areas under construction:
NOI-1 Construction Noise Best Management Practices
The project applicant shall reduce construction noise levels at the adjacent single- and multi-family
uses to the south of the project site, through measures such as, but not limited to:
▪ Locate stationary equipment as far as practicable from occupied on-site dwelling units.
▪ Electrically powered equipment instead of internal combustion equipment shall be used where
feasible.
▪ The use of bells, whistles, alarms, and horns shall be restricted to safety warning purposes only.
▪ Construction areas for staging and warming up shall be located as far as possible from occupied
on-site dwelling units.
Operation
The project would introduce sources of operational noise to the site, including mechanical
equipment (i.e., HVAC units). Assumptions for these sources are discussed in Section 3.3. Noise
levels at the nearest properties from each noise source and their combined noise levels are shown
in Table 14 and ground-floor noise contours are shown in Figure 6. As shown in Table 14,
operational HVAC noise on the project site would generate noise levels up to 47 dBA Leq at nearby
residential-zoned properties. The operational noise from project HVAC mechanical equipment
would not exceed Fontana’s operational noise standards of 65 dBA Leq.

See Appendix B for SoundPLAN results.
Off-site Traffic Noise Increases
The project would generate new vehicle trips that would increase noise levels on nearby roadways.
As discussed in the project Traffic Study, the project is anticipated to generate a net total of
17,352 daily vehicle trips with 1,786 AM peak hour trips and 1,531 PM peak hour trips (Urban
Crossroads 2021). The Traffic Study area includes roadway segments of Duncan Canyon Road, Citrus
Avenue, Casa Grande, Summit Avenue, Sierra Avenue, and Lytle Creek Road (Urban Crossroads
2021). Roadway segment volumes with and without project-generated traffic are shown in Table 15.
The project would make alterations to roadway alignments of Lytle Creek Road, however,
substantial changes to the vehicle classifications mix on local roadways is not expected. Therefore,
the primary factor affecting off-site noise levels would be increased traffic volumes. Noise levels
with and without project generated traffic were developed based on algorithms and reference
levels from FHWA TNM. Noise levels with and without project-generated traffic are shown in Table
15.
As discussed in Section 2.1, Overview of Sound, a doubling of the energy of a noise source, such as
doubling of traffic volume, would increase the noise level by 3 dBA. It is widely accepted that the
average healthy ear can barely perceive changes of 3 dBA, increase or decrease. Project-generated
traffic noise level increases would range between less than 1 dBA CNEL to 4 dBA CNEL. Two project
area roadway segments of Citrus Avenue, from the north to Lytle Creek Road and Lytle Creek Road
to Duncan Canyon Road, would experience the largest traffic noise level increases, 3 dBA CNEL and
4 dBA CNEL, respectively, when comparing 2023 to 2023 with and without project traffic scenarios.
It should be noted that there are no existing noise sensitive receivers along these roadway
segments.
For purposes of this analysis, a significant impact would occur if project-related traffic increases the
ambient noise environment of noise-sensitive land uses by 3 dBA or more if the locations are
subject to noise levels in excess of conditionally compatible levels, or by 5 dBA or more if the
locations are not subject to noise levels in excess of the conditionally compatible levels identified in
the City of Fontana General Plan. Therefore, impacts would be less than significant.

Traffic Noise Land Use Compatibility
As discussed in Section 2.5, the Fontana General Plan Noise and Safety Element includes the criteria
for evaluating whether a given land use is compatible with the existing noise environment. The
project proposes a mix of uses, including noise sensitive residential uses. For noise sensitive
residential uses, noise levels up to 65 dBA CNEL are considered compatible with the City’s Noise and
Safety Element exterior noise criteria for land use compatibility.
Following the methodology discussed in Section 3.4, traffic noise levels were modeled at a series of
receivers at and residential building façades and exterior use areas were calculated in SoundPLAN.
Modeled noise levels are summarized in Table 16 and ground-floor noise contours are shown in
Figure 7.

For multi-family residential uses, the exterior noise level standard is typically applied at common
outdoor activity areas. Planning Areas 1b, 3, and 4 include a common outdoor activity area at the
pool areas. As shown in Table 16, the pool areas would be exposed to traffic noise levels below 65
dBA CNEL. These noise levels would not conflict with the City’s compatibility standards.
The commercial component of the Specific Plan would generally be exposed to traffic noise levels
between 64 and 77 dBA CNEL, see Table 16. The commercial uses of Planning Area 2, Planning
Area 4, Planning Area 5a, Planning Area 5b, and Planning Area 6 would be exposed to traffic noise
levels up to 77 dBA CNEL at facades adjacent to I-15. The commercial uses of Planning Area 4 would
be exposed to traffic noise levels up to 71 dBA CNEL at the nearest façade adjacent to Duncan
Canyon Road. The proposed commercial uses would not generally be considered noise sensitive.
These noise levels would not conflict with the City’s compatibility standards and the commercial
component of the project would be compatible with the ambient noise environment.
Planning Area 1a residential buildings would be exposed to traffic noise levels between 57 dBA and
72 dBA CNEL at first through third floor facades. The south facades of Buildings 1 and 3 would be
exposed to Duncan Canyon Road traffic noise levels of 70 dBA to 72 dBA CNEL at the first through
third floors. The west façade of Buildings 1 and 2 would be exposed to Lytle Creek Road traffic noise
levels of 66 dBA to 68 dBA CNEL at the second and third floors.
Planning Area 1b residential buildings would be exposed to traffic noise levels between 53 dBA and
70 dBA CNEL at first through third floor facades. The west facades of Buildings 1, 2, 4, 5, and north
façade of Building 7 would be exposed to Lytle Creek Road traffic noise levels of 66 dBA to 70 dBA
CNEL at the first through third floors.

Citrus Avenue traffic noise level of 66 dBA at the third-floor façade.

Planning Area 4 residential buildings would be exposed to traffic noise levels between 63 dBA and
75 dBA CNEL at the first through third floor facades. The west, northwest, and southwest facades of
Buildings 2, 4, 6, and 9 would be exposed to I-15 traffic noise levels of 67 dBA to 75 dBA CNEL at the
first through third floor facades. The south facades of Buildings 1 and 2 would also be exposed to
I-15 traffic noise levels of 69 dBA to 74 dBA CNEL at the first through third floor facades.
As noise levels would exceed 65 dBA CNEL, the project would be conditionally acceptable with the
noise environment based on community noise exposure standards from the General Plan.
Therefore, additional analysis to determine whether interior noise levels would not exceed 45 dBA
CNEL are discussed below.
The FHWA’s guidelines indicate that modern building construction generally provides an exterior-to-
interior noise level reduction of 20 to 35 dBA with closed windows (FHWA 2011). Based on a noise
exposure level of up to 75 dBA CNEL and a noise attenuation of 20 dBA, the interior noise levels
would be up to 55 dBA CNEL. Therefore, where building façade noise levels would exceed 65 dBA
CNEL (i.e., residential units adjacent to I-15 and Duncan Canyon Road), interior noise levels for the
project would not comply with the City’s interior noise standard of 45 dBA CNEL for residential uses.
Implementation of recommendation NOI-2, a detailed exterior-to-interior noise analysis of the noise
reduction requirements and needed noise insulation features included in the design to achieve
compliance with the interior noise standard, would be required.
Recommendation
NOI-2 Exterior-to-Interior Noise Analysis
For residential units where exterior noise levels exceed 65 dBA CNEL, the project applicant shall
coordinate with the project architects and other contractors to ensure compliance with the 45 dBA
CNEL interior noise level standard. This shall be achieved through additional exterior-to-interior
noise analysis and incorporation of noise attenuation features once specific building plan
information is available. The information in the analysis shall include wall heights and lengths, room
volumes, window and door tables typical for a building plan, as well as information on other
openings in the building shell. With this specific building plan information, the analysis shall
determine the predicted interior noise levels at the planned on-site buildings. If predicted noise
levels are found to be in excess of the applicable limit, the report shall identify architectural
materials or techniques that could be included to reduce noise levels to the applicable limit. The
project applicant shall comply with mitigation measures included in the interior noise report to
reduce interior noise levels where applicable noise limits are exceeded.
4.2 Item 2 – Vibration
Item: Would the project result in generation of excessive groundborne vibration or groundborne
noise levels? (Less Than Significant Impact)
Construction activities known to generate excessive groundborne vibration, such as pile driving,
would not be conducted by the project. The greatest anticipated source of vibration during general
project construction activities would be from a dozer, which may be used within 50 feet of the
nearest on-site vibration sensitive use. A dozer creates approximately 0.089 in./sec. PPV at a
distance of 25 feet (Caltrans 2020). This would equal a vibration level of 0.0315 in./sec. PPV at
Impact Analysis
Noise and Vibration Study 39
50 feet. This vibration level is lower than the human annoyance threshold of 0.24 in./sec. PPV and
the structural damage threshold of 0.4 in./sec. PPV. Therefore, temporary impacts associated with
construction would be less than significant.
The project does not include any substantial vibration sources associated with operation. Therefore,
operational vibration impacts would be less than significant.
4.3 Item 3 – Airport Noise
Item: 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? (No Impact)
The Ontario International Airport is approximately 10.7 miles southwest of the project site, and San
Bernardino International Airport is approximately 12.9 miles southeast of the project site. The
proposed project would not be situated within two miles of a public airport, public use airport, or an
airport land use plan area. Therefore, no substantial noise exposure from airport noise would occur
to construction workers, users, or employees of the project, and no impacts would occur.

5 Conclusions
The project would generate both temporary construction-related noise and long-term noise
associated with operation of the project. Implementation of recommendation NOI-1 (Construction
Noise Best Management Practices) would include locating stationary equipment as far as practicable
from occupied on-site dwelling units, using electrically powered equipment instead of internal
combustion equipment where feasible, restricting the use of bells, whistles, alarms and horns, and
locating construction staging and warming areas as far as possible from occupied on-site dwelling
units. With implementation of recommendation NOI-1 and complying with daytime construction
hours 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, construction noise levels would be reduced to a level that does not exceed applicable
noise level limits from the Fontana Municipal Code Construction noise would not exceed Fontana
Municipal Code noise standards at the nearby land uses and impacts from construction noise would
be less than significant.
Operational HVAC activities on the project site would generate noise levels up to 47 dBA Leq at
nearby residential-zoned properties to the south and east of the site. The operational noise from
the mechanical equipment would comply with Fontana’s daytime and nighttime noise standards,
and impacts would be less than significant.
Project-generated traffic would generate an increase of up to 4 dBA CNEL on analyzed roadways.
The roadway segments of Citrus Avenue, from the north to Lytle Creek Road and Lytle Creek Road to
Duncan Canyon Road, would experience the largest traffic noise level increases, 3 dBA CNEL and
4 dBA CNEL, respectively, when comparing 2023 to 2023 with and without project traffic scenarios.
It should be noted that there are no existing noise sensitive receivers along these roadway segments
to be impacted. Furthermore, the project’s traffic noise increase would not exceed 60 dBA CNEL, the
City’s threshold for exterior noise impacts on residential areas. Therefore, off-site traffic impacts
would be less than significant.
Traffic noise levels at the residential common outdoor activity areas (pools areas) would range
between 53 dBA to 62 dBA CNEL and traffic noise levels at residential building façades would reach
75 dBA CNEL for residential buildings adjacent to Duncan Canyon Road and I-15. Therefore, based
on community noise exposure standards from the General Plan, the proposed uses are conditionally
compatible with the noise environment. With an exterior-to-interior noise level reduction of at least
20 dBA, interior noise levels for the project would exceed the City’s interior noise standard of
45 dBA CNEL. With implementation of NOI-2 (Exterior-to-Interior Noise Analysis) incorporation of
noise attenuation features once specific building plan information is available would comply with
the City’s interior noise threshold and impacts from interior traffic noise would be less than
significant.
The project would generate groundborne vibration during construction. Groundborne vibration
would not exceed the applicable vibration threshold at the nearest structures, and construction-
related vibration impacts would be less than significant.
The project site is outside the noise contours for the Ontario International Airport and San
Bernardino International Airport. Therefore, no substantial noise exposure would occur to
construction workers, employees, or users of the project from aircraft noise.

FEATURES AND BENEFITS (cont.)
Efficient operation
These air cooled condensing units will provide EER’s up
to 12.6 (tested in accordance with ASHRAE 90.1
standards).
This high efficiency will help reduce overall operating
cost and energy consumption.
Controls for performance dependability
The 38AU condensing units offer operating controls and
components designed for performance dependability. The
high efficiency hermetic scroll compressor is engineered
for long life and durability. The compressors include
vibration isolation for quiet operation. The high-pressure
switch protects the entire refrigeration system from
abnormally high operating pressures. A low-pressure
switch protects the system from loss of charge. These
units also include anti-short-cycling protection, which
helps to protect the units against compressor failure.
All units include a crankcase heater to eliminate liquid
slugging at start-up. Each unit comes standard with the
Comfort Alertt control system. This provides:
S System Go LED indicator
S Fault LED indicator
S Compressor fault LED indicator
S Phase loss protection
S Phase reversal protection
S Safety pressure indicator
S Anti--short cycle protection
Innovative Carrier 40RU packaged air hand-
lers are custom matched to 38AUZ/D condens-
ing units
Information on matching 40RU DX packaged air handler
follows for convenience. See separate product data for
more details. The 40RU Series has excellent fan
performance, efficient direct-expansion (DX) coils, a
unique combination of indoor-air quality features, and is
easy to install. Its versatility and state-of-the-art features
help to ensure economical performance of the split system
both now and in the future.
Indoor--air quality (IAQ) features
The unique combination of IAQ features in the 40RU
Series air handlers help to ensure that only clean, fresh,
conditioned air is delivered to the occupied space.
Direct-expansion (DX) 4 row cooling coils prevent the
build-up of humidity in the room, even during part-load
conditions.
Standard 2-in. (51mm) disposable filters remove dust and
airborne particles from the occupied space for cleaner air.
The pitched, non-corroding drain pan can be adjusted for
a right-hand or left-hand connection to suit many
applications and provide positive drainage and prevent
standing condensate.
The accessory economizer can provide ventilation air to
improve indoor-air quality by using demand control
ventilation. When used in conjunction with Carrier
Comfort System and CO2 sensors, the economizer admits
fresh outdoor air to replace stale, recirculated indoor air.
Economy
The 40RU Series packaged air handlers provide reduced
installation expense and energy-efficient performance.
Quick installation is ensured by the multipoise design.
Units can be installed in either the horizontal or vertical
configuration without modifications. Fan motors and
contactors are pre--wired and thermostatic expansion
valves (TXVs) are factory-installed on all 40RU models.
High efficiency, precision-balanced fans minimize air
turbulence, surging, and unbalanced operation, cutting
operation expenses.
The economizer accessory precisely controls the blend of
outdoor air and room air to achieve comfort levels. When
the outside air enthalpy is suitable, outside air dampers
can fully open to provide “free” cooling without
energizing mechanical cooling.
Rugged dependability
The 40RU series units are made to last. The die-formed
galvanized steel panels ensure structural integrity under
all operating conditions. Galvanized steel fan housings are
securely mounted to a die-formed galvanized steel fan
deck.
Rugged pillow-block bearings (40RU14) are securely
fastened to the solid steel fan shaft with split collets and
clamp locking devices. Smaller unit sizes have spider-type
bearings.
Coil flexibility
Model 40RU direct- expansion coils have galvanized steel
casings; inlet and outlet connections are on the same end.
The coils are designed for use with Puron (R--410A)
refrigerant and have
3/8-in. diameter copper tubes
mechanically bonded to aluminum sine-wave fins. The
coils include matched, factory-installed thermostatic
expansion valves (TXVs) with matching distributor
nozzles and offers a removable power element and
extended connections.
Easier installation and service
The multipoise design and component layout ensures
quick unit installation and operation. Units can be
converted from horizontal to vertical operation by simply
repositioning the unit. Drain pan connections are
duplicated on both sides of the unit. The filters, motor,
drive, TXVs, and coil connections are all easily accessed
by removing a single side panel.38AU

E-coated aluminum-fin coils have a flexible and durable
epoxy coating uniformly applied to all coil surfaces.
Unlike brittle phenolic dip and bake coatings, E-coating
provides superior protection with unmatched flexibility,
edge coverage, metal adhesion, thermal performance, and
most importantly, corrosion resistance.
E-coated coils provide this protection since all coil
surfaces are completely encapsulated from environmental
contamination. This coating is especially suitable in
industrial environments.
Pre--coated coils (RTPF coils only) provide protection in
mild coastal environments.
–29_C (–20_F) low-ambient temperature kit option
(MotorMaster Ir)controls outdoor-fan motor operation
to maintain the correct head pressure at low outdoor
ambient temperatures.
Louvered hail guard package protects coils against
damage from flying debris and hail.
Non-fused disconnect switch is used to remove power
locally at the condensing unit. This switch also includes a
power lockout capability to protect the service person.
This lockout switch saves the service person time and
effort because there is no need to access a distant
disconnect switch while servicing the unit.
NOTE: Non--fused disconnect switch cannot be used
when unit MOCP electrical rating exceeds 80 amps.

Two-row hot water coils have 5/8-in. diameter copper
tubes mechanically bonded to aluminum plate fins. Coils
have non-ferrous headers.
One-row steam coil has 1-in. OD copper tube and
aluminum fins. The Inner Distributing Tube (IDT) design
provides uniform temperatures across the coil face. The
IDT steam coils are especially suited to applications
where sub-freezing air enters the unit.
Electric resistance heat coils have an open-wire design
and are mounted in a rigid frame. Safety cutouts for high
temperature conditions are standard.
Economizer (enthalpy controlled)provides ventilation
air and provides “free” cooling if the outside ambient
temperature and humidity are suitable. The economizer
can also be used in conjunction with Carrier Comfort
System thermostats and CO2 sensors to help meet indoor
air quality requirements. The economizer can be used in
both vertical and horizontal positions.
Discharge plenum directs the air discharge into the
occupied space; integral horizontal and vertical louvers
enable redirection of airflow. This accessory is available
unpainted or painted.
Return-air grille provides a protective barrier over the
return-air opening and gives a finished appearance to units
installed in the occupied space. This accessory is available
unpainted or painted.
Subbase provides a stable, raised platform and room for
condensate drain connection for floor-mounted units. This
accessory is available unpainted or painted.
Overhead suspension package includes necessary
brackets to support units in horizontal installations.
CO2 sensors can be used in conjunction with the
economizer accessory to help meet indoor air quality
requirements. The sensor signals the economizer to open
when the CO2 level in the space exceeds the setpoint. A

FEATURES AND BENEFITS (cont.)
Efficient operation
These air cooled condensing units will provide EER’s up
to 12.6 (tested in accordance with ASHRAE 90.1
standards).
This high efficiency will help reduce overall operating
cost and energy consumption.
Controls for performance dependability
The 38AU condensing units offer operating controls and
components designed for performance dependability. The
high efficiency hermetic scroll compressor is engineered
for long life and durability. The compressors include
vibration isolation for quiet operation. The high-pressure
switch protects the entire refrigeration system from
abnormally high operating pressures. A low-pressure
switch protects the system from loss of charge. These
units also include anti-short-cycling protection, which
helps to protect the units against compressor failure.
All units include a crankcase heater to eliminate liquid
slugging at start-up. Each unit comes standard with the
Comfort Alertt control system. This provides:
S System Go LED indicator
S Fault LED indicator
S Compressor fault LED indicator
S Phase loss protection
S Phase reversal protection
S Safety pressure indicator
S Anti--short cycle protection
Innovative Carrier 40RU packaged air hand-
lers are custom matched to 38AUZ/D condens-
ing units
Information on matching 40RU DX packaged air handler
follows for convenience. See separate product data for
more details. The 40RU Series has excellent fan
performance, efficient direct-expansion (DX) coils, a
unique combination of indoor-air quality features, and is
easy to install. Its versatility and state-of-the-art features
help to ensure economical performance of the split system
both now and in the future.
Indoor--air quality (IAQ) features
The unique combination of IAQ features in the 40RU
Series air handlers help to ensure that only clean, fresh,
conditioned air is delivered to the occupied space.
Direct-expansion (DX) 4 row cooling coils prevent the
build-up of humidity in the room, even during part-load
conditions.
Standard 2-in. (51mm) disposable filters remove dust and
airborne particles from the occupied space for cleaner air.
The pitched, non-corroding drain pan can be adjusted for
a right-hand or left-hand connection to suit many
applications and provide positive drainage and prevent
standing condensate.
The accessory economizer can provide ventilation air to
improve indoor-air quality by using demand control
ventilation. When used in conjunction with Carrier
Comfort System and CO2 sensors, the economizer admits
fresh outdoor air to replace stale, recirculated indoor air.
Economy
The 40RU Series packaged air handlers provide reduced
installation expense and energy-efficient performance.
Quick installation is ensured by the multipoise design.
Units can be installed in either the horizontal or vertical
configuration without modifications. Fan motors and
contactors are pre--wired and thermostatic expansion
valves (TXVs) are factory-installed on all 40RU models.
High efficiency, precision-balanced fans minimize air
turbulence, surging, and unbalanced operation, cutting
operation expenses.
The economizer accessory precisely controls the blend of
outdoor air and room air to achieve comfort levels. When
the outside air enthalpy is suitable, outside air dampers
can fully open to provide “free” cooling without
energizing mechanical cooling.
Rugged dependability
The 40RU series units are made to last. The die-formed
galvanized steel panels ensure structural integrity under
all operating conditions. Galvanized steel fan housings are
securely mounted to a die-formed galvanized steel fan
deck.
Rugged pillow-block bearings (40RU14) are securely
fastened to the solid steel fan shaft with split collets and
clamp locking devices. Smaller unit sizes have spider-type
bearings.
Coil flexibility
Model 40RU direct- expansion coils have galvanized steel
casings; inlet and outlet connections are on the same end.
The coils are designed for use with Puron (R--410A)
refrigerant and have
3/8-in. diameter copper tubes
mechanically bonded to aluminum sine-wave fins. The
coils include matched, factory-installed thermostatic
expansion valves (TXVs) with matching distributor
nozzles and offers a removable power element and
extended connections.
Easier installation and service
The multipoise design and component layout ensures
quick unit installation and operation. Units can be
converted from horizontal to vertical operation by simply
repositioning the unit. Drain pan connections are
duplicated on both sides of the unit. The filters, motor,
drive, TXVs, and coil connections are all easily accessed
by removing a single side panel.38AU

E-coated aluminum-fin coils have a flexible and durable
epoxy coating uniformly applied to all coil surfaces.
Unlike brittle phenolic dip and bake coatings, E-coating
provides superior protection with unmatched flexibility,
edge coverage, metal adhesion, thermal performance, and
most importantly, corrosion resistance.
E-coated coils provide this protection since all coil
surfaces are completely encapsulated from environmental
contamination. This coating is especially suitable in
industrial environments.
Pre--coated coils (RTPF coils only) provide protection in
mild coastal environments.
–29_C (–20_F) low-ambient temperature kit option
(MotorMaster Ir)controls outdoor-fan motor operation
to maintain the correct head pressure at low outdoor
ambient temperatures.
Louvered hail guard package protects coils against
damage from flying debris and hail.
Non-fused disconnect switch is used to remove power
locally at the condensing unit. This switch also includes a
power lockout capability to protect the service person.
This lockout switch saves the service person time and
effort because there is no need to access a distant
disconnect switch while servicing the unit.
NOTE: Non--fused disconnect switch cannot be used
when unit MOCP electrical rating exceeds 80 amps.

IDT steam coils are especially suited to applications
where sub-freezing air enters the unit.
Electric resistance heat coils have an open-wire design
and are mounted in a rigid frame. Safety cutouts for high
temperature conditions are standard.
Economizer (enthalpy controlled)provides ventilation
air and provides “free” cooling if the outside ambient
temperature and humidity are suitable. The economizer
can also be used in conjunction with Carrier Comfort
System thermostats and CO2 sensors to help meet indoor
air quality requirements. The economizer can be used in
both vertical and horizontal positions.
Discharge plenum directs the air discharge into the
occupied space; integral horizontal and vertical louvers
enable redirection of airflow. This accessory is available
unpainted or painted.
Return-air grille provides a protective barrier over the
return-air opening and gives a finished appearance to units
installed in the occupied space. This accessory is available
unpainted or painted.
Subbase provides a stable, raised platform and room for
condensate drain connection for floor-mounted units. This
accessory is available unpainted or painted.
Overhead suspension package includes necessary
brackets to support units in horizontal installations.
CO2 sensors can be used in conjunction with the
economizer accessory to help meet indoor air quality
requirements. The sensor signals the economizer to open
when the CO2 level in the space exceeds the setpoint. A
Carrier Comfort System programmable thermostat can
also be used to override the sensor if the outside-air
temperature is too high or too low.
Condensate drain trap includes an overflow shutoff
switch that can be wired to turn off the unit if the trap
becomes plugged. The kit also includes a wire harness
that can be connected to an alarm if desired. The
transparent trap is designed for easy service and
maintenance.38AU
