EXECUTIVE SUMMARY
Urban Crossroads, Inc. has prepared this noise study to determine the potential noise impacts
and the necessary noise mitigation measures, if any, for the proposed Desert Wave development
(“Project”). The Project site is located west of Desert Willow Drive, in the City of Palm Desert. It
is our understanding that the Project is to consist of a 6.0-acre surf lagoon with restaurant, café,
bar, and two hotels with a maximum of 350 rooms and a maximum of 88 villas. This study has
been prepared to satisfy applicable City of Palm Desert standards and thresholds of significance
based on guidance provided by Appendix G of the California Environmental Quality Act (CEQA)
Guidelines. (1)
OFF-SITE TRAFFIC NOISE ANALYSIS
Traffic generated by the operation of the Project will influence the traffic noise levels in
surrounding off-site areas. To quantify the off-site traffic noise increases on the surrounding off-
site areas, the changes in traffic noise levels on 22 study-area roadway segments were calculated
based on the change in the average daily traffic (ADT) volumes. The traffic noise levels provided
in this analysis are based on the traffic forecasts found in the Desert Wave Traffic Impact Analysis
prepared by Urban Crossroads, Inc. (2) To assess the off-site noise level impacts associated with
the proposed Project, noise contour boundaries were developed for Existing (2019), Existing plus
Ambient Growth (EA) 2022, and EA plus Cumulative (EAC) 2022 conditions.
The analysis shows that the unmitigated Project-related traffic noise level increases under all
with Project traffic scenarios are considered less than significant impacts at land uses adjacent
to the study area roadway segments.
As a part of the Environmental Impact Report for the Project, three land use alternatives were
compared in terms of trip generation for the Project site, including: retail and multi-family
housing, single-family detached housing, and hotel use. Based on the Alternatives Trip
Generation Summary prepared by Urban Crossroads, Inc., all Project land use alternatives would
generate fewer daily trips than those of the Project. Therefore, off-site traffic noise level
increases related to the three land use alternatives are anticipated to be lower than those
presented in this report for the proposed Project land use. Moreover, since Project off-site traffic
noise level increases are shown in this report to result in less than significant noise impacts, the
three land use alternatives, which would generate fewer daily trips, would therefore, also result
in equivalent or lower off-site traffic noise level impacts.
OPERATIONAL NOISE ANALYSIS
Using reference noise levels to represent the expected noise sources from the Desert Wave site,
this analysis estimates the Project-related stationary-source noise levels at nearby sensitive
receiver locations under typical and special event conditions.

TYPICAL OPERATIONAL NOISE LEVELS
The typical activities associated with the proposed Desert Wave are anticipated to include surf
lagoon/wave machine activities, outdoor pool/spa activities, parking lot vehicle movements,
outdoor game activities, and roof-top air conditioning units. The typical condition operational
noise analysis shows that the unmitigated Project-related stationary-source noise levels at all
receiver locations will satisfy the City of Palm Desert base exterior noise level standards.
Moreover, the results of the analysis indicate that the unmitigated Project operational noise
levels will not contribute a long-term operational noise level impact to the existing ambient noise
environment. Therefore, the operational noise level impacts associated with the proposed 24-
hour seven days per week Project activities, such as the surf lagoon/wave machine activities,
outdoor pool/spa activities, parking lot vehicle movements, outdoor game activities, and roof-
top air conditioning units, are considered less than significant under typical conditions.
SPECIAL EVENT OPERATIONAL NOISE LEVELS
Project special event operational noise levels are analyzed for compliance with City of Palm
Desert Municipal Code base exterior noise level limits. Special event activities within the Project
site are anticipated to include live and/or amplified music, and as such, the special event
condition analysis includes all previously analyzed typical operational noise sources, with the
addition of live and/or amplified music operating simultaneously. The special event condition
operational noise analysis shows that the unmitigated Project-related stationary-source noise
levels at all receiver locations will satisfy the City of Palm Desert base exterior noise level
standards.
CONSTRUCTION NOISE ANALYSIS
Construction-related noise impacts are expected to create temporary and intermittent high-level
noise conditions at receivers surrounding the Project site. Using sample reference noise levels
to represent the planned construction activities of the Desert Wave site, this analysis estimates
the Project-related construction noise levels at nearby sensitive receiver locations. Since the City
of Palm Desert General Plan and Municipal Code do not identify specific construction noise level
thresholds, a threshold is identified based on the National Institute for Occupational Safety and
Health (NIOSH) limits for construction noise. The Project-related short-term construction noise
levels are expected to range from 28.5 to 68.4 dBA Leq and will satisfy the 85 dBA Leq threshold
identified by the National Institute for Occupational Safety and Health (NIOSH) at all receiver
locations. Therefore, based on the results of this analysis, all nearby sensitive receiver locations
will experience less than significant impacts due to Project construction noise levels.

CONSTRUCTION VIBRATION ANALYSIS
Construction activity can result in varying degrees of ground vibration, depending on the
equipment and methods used, distance to the affected structures and soil type. It is expected
that ground-borne vibration from Project construction activities would cause only intermittent,
localized intrusion. This analysis shows the highest construction vibration levels are expected to
approach 0.009 in/sec RMS, which is below the County of Riverside vibration standard of 0.01
in/sec RMS at all receiver locations. Therefore, the Project-related vibration impacts are
considered less than significant during the construction activities at the Project site.
Further, the Project-related construction vibration levels do not represent levels capable of
causing building damage to nearby residential homes. The FTA identifies construction vibration
levels capable of building damage ranging from 0.12 to 0.5 in/sec PPV. (3) The peak Project-
construction vibration levels approaching 0.013 in/sec PPV will remain below the FTA vibration
levels for building damage at the residential homes near the Project site. Moreover, the impacts
at the site of the closest sensitive receivers are unlikely to be sustained during the entire
construction period, but will occur rather only during the times that heavy construction
equipment is operating adjacent to the Project site perimeter.
SUMMARY OF SIGNIFICANCE FINDINGS
The results of this Desert Wave Noise Impact Analysis are summarized below based on the
significance criteria in Section 4 of this report. Table ES-1 shows the findings of significance for
each potential noise and/or vibration impact before and after any required mitigation measures.

1 INTRODUCTION
This noise analysis has been completed to determine the noise impacts associated with the
development of the proposed Desert Wave (“Project”). This noise study briefly describes the
proposed Project, provides information regarding noise fundamentals, describes the local
regulatory setting, provides the study methods and procedures for traffic noise analysis, and
evaluates the future exterior noise environment. In addition, this study includes an analysis of
the potential Project-related long-term operational and short-term construction noise and
vibration impacts.
1.1 SITE LOCATION
The proposed Desert Wave site is located west of Desert Willow Drive, in the City of Palm Desert,
as shown on Exhibit 1-A.
The Project site is mostly vacant with an existing parking lot located in the northwestern corner.
Existing land uses near the site include a golf course to the north, south, and east, and an existing
hotel use located west of the Project site.
1.2 PROJECT DESCRIPTION
It is our understanding that the Project is to consist of a 6.0-acre surf lagoon with restaurant,
café, bar, and two hotels with a maximum of 350 rooms and a maximum of 88 villas, as shown
on Exhibit 1-B.
The typical on-site Project-related noise sources are expected to include: surf lagoon/wave
machine activities, outdoor pool/spa activities, parking lot vehicle movements, outdoor game
activities, and roof-top air conditioning units. This noise analysis is intended to describe noise
level impacts associated with the expected typical and special event operational conditions at
the Project site. Special event activities within the Project site are anticipated to include live
and/or amplified music, and as such, the special event condition analysis includes all previously
identified typical operational noise sources with the addition of live and/or amplified music
operating simultaneously.

2 FUNDAMENTALS
Noise has been simply defined as "unwanted sound." Sound becomes unwanted when it
interferes with normal activities, when it causes actual physical harm or when it has adverse
effects on health. Noise is measured on a logarithmic scale of sound pressure level known as a
decibel (dB). A-weighted decibels (dBA) approximate the subjective response of the human ear
to broad frequency noise source by discriminating against very low and very high frequencies of
the audible spectrum. They are adjusted to reflect only those frequencies which are audible to
the human ear. Exhibit 2-A presents a summary of the typical noise levels and their subjective
loudness and effects that are described in more detail below.
EXHIBIT 2-A: TYPICAL NOISE LEVELS
Source: Environmental Protection Agency Office of Noise Abatement and Control, Information on Levels of Environmental Noise
Requisite to Protect Public Health and Welfare with an Adequate Margin of Safety (EPA/ONAC 550/9-74-004) March 1974.
2.1 RANGE OF NOISE
Since the range of intensities that the human ear can detect is so large, the scale frequently used
to measure intensity is a scale based on multiples of 10, the logarithmic scale. The scale for
measuring intensity is the decibel scale. Each interval of 10 decibels indicates a sound energy ten
times greater than before, which is perceived by the human ear as being roughly twice as loud.
(4) The most common sounds vary between 40 dBA (very quiet) to 100 dBA (very loud). Normal
conversation at three feet is roughly at 60 dBA, while loud jet engine noises equate to 110 dBA
Desert Wave Noise Impact Analysis
11826-03 Noise Study
10
at approximately 100 feet, which can cause serious discomfort. (5) Another important aspect of
noise is the duration of the sound and the way it is described and distributed in time.
2.2 NOISE DESCRIPTORS
Environmental noise descriptors are generally based on averages, rather than instantaneous,
noise levels. The most commonly used figure is the equivalent level (Leq). Equivalent sound levels
are not measured directly but are calculated from sound pressure levels typically measured in A-
weighted decibels (dBA). The equivalent sound level (Leq) represents a steady state sound level
containing the same total energy as a time varying signal over a given sample period and is
commonly used to describe the “average” noise levels within the environment.
Peak hour or average noise levels, while useful, do not completely describe a given noise
environment. Noise levels lower than peak hour may be disturbing if they occur during times
when quiet is most desirable, namely evening and nighttime (sleeping) hours. To account for
this, the Community Noise Equivalent Level (CNEL), representing a composite 24-hour noise level
is utilized. The CNEL is the weighted average of the intensity of a sound, with corrections for time
of day, and averaged over 24 hours. The time of day corrections require the addition of 5 decibels
to dBA Leq sound levels in the evening from 7:00 p.m. to 10:00 p.m., and the addition of 10
decibels to dBA Leq sound levels at night between 10:00 p.m. and 7:00 a.m. These additions are
made to account for the noise sensitive time periods during the evening and night hours when
sound appears louder. CNEL does not represent the actual sound level heard at any time, but
rather represents the total sound exposure. The City of Palm Desert relies on the 24-hour CNEL
level to assess land use compatibility with transportation related noise sources.
2.3 SOUND PROPAGATION
When sound propagates over a distance, it changes in level and frequency content. The way noise
reduces with distance depends on the following factors.
2.3.1 GEOMETRIC SPREADING
Sound from a localized source (i.e., a stationary point source) propagates uniformly outward in a
spherical pattern. The sound level attenuates (or decreases) at a rate of 6 dB for each doubling
of distance from a point source. Highways consist of several localized noise sources on a defined
path and hence can be treated as a line source, which approximates the effect of several point
sources. Noise from a line source propagates outward in a cylindrical pattern, often referred to
as cylindrical spreading. Sound levels attenuate at a rate of 3 dB for each doubling of distance
from a line source. (4)
2.3.2 GROUND ABSORPTION
The propagation path of noise from a highway to a receptor is usually very close to the ground.
Noise attenuation from ground absorption and reflective wave canceling adds to the attenuation
associated with geometric spreading. Traditionally, the excess attenuation has also been
expressed in terms of attenuation per doubling of distance. This approximation is usually
Desert Wave Noise Impact Analysis
11826-03 Noise Study
11
sufficiently accurate for distances of less than 200 ft. For acoustically hard sites (i.e., sites with a
reflective surface between the source and the receptor, such as a parking lot or body of water),
no excess ground attenuation is assumed. For acoustically absorptive or soft sites (i.e., those
sites with an absorptive ground surface between the source and the receptor such as soft dirt,
grass, or scattered bushes and trees), an excess ground attenuation value of 1.5 dB per doubling
of distance is normally assumed. When added to the cylindrical spreading, the excess ground
attenuation results in an overall drop-off rate of 4.5 dB per doubling of distance from a line
source. (6)
2.3.3 ATMOSPHERIC EFFECTS
Receptors located downwind from a source can be exposed to increased noise levels relative to
calm conditions, whereas locations upwind can have lowered noise levels. Sound levels can be
increased at large distances (e.g., more than 500 feet) due to atmospheric temperature inversion
(i.e., increasing temperature with elevation). Other factors such as air temperature, humidity,
and turbulence can also have significant effects. (4)
2.3.4 SHIELDING
A large object or barrier in the path between a noise source and a receptor can substantially
attenuate noise levels at the receptor. The amount of attenuation provided by shielding depends
on the size of the object and the frequency content of the noise source. Shielding by trees and
other such vegetation typically only has an “out of sight, out of mind” effect. That is, the
perception of noise impact tends to decrease when vegetation blocks the line-of-sight to nearby
residents. However, for vegetation to provide a substantial, or even noticeable, noise reduction,
the vegetation area must be at least 15 feet in height, 100 feet wide and dense enough to
completely obstruct the line-of sight between the source and the receiver. This size of vegetation
may provide up to 5 dBA of noise reduction. The FHWA does not consider the planting of
vegetation to be a noise abatement measure. (6)
2.4 NOISE CONTROL
Noise control is the process of obtaining an acceptable noise environment for an observation
point or receptor by controlling the noise source, transmission path, receptor, or all three. This
concept is known as the source-path-receptor concept. In general, noise control measures can
be applied to these three elements.
2.5 NOISE BARRIER ATTENUATION
Effective noise barriers can reduce noise levels by 10 to 15 dBA, cutting the loudness of traffic
noise in half. A noise barrier is most effective when placed close to the noise source or receptor.
Noise barriers, however, do have limitations. For a noise barrier to work, it must be high enough
and long enough to block the path of the noise source. (6)

2.6 LAND USE COMPATIBILITY WITH NOISE
Some land uses are more tolerant of noise than others. For example, schools, hospitals,
churches, and residences are more sensitive to noise intrusion than are commercial or industrial
developments and related activities. As ambient noise levels affect the perceived amenity or
livability of a development, so too can the mismanagement of noise impacts impair the economic
health and growth potential of a community by reducing the area’s desirability as a place to live,
shop and work. For this reason, land use compatibility with the noise environment is an
important consideration in the planning and design process. The FHWA encourages State and
Local government to regulate land development in such a way that noise-sensitive land uses are
either prohibited from being located adjacent to a highway, or that the developments are
planned, designed, and constructed in such a way that noise impacts are minimized. (7)
2.7 COMMUNITY RESPONSE TO NOISE
Community responses to noise may range from registering a complaint by telephone or letter, to
initiating court action, depending upon everyone’s susceptibility to noise and personal attitudes
about noise. Several factors are related to the level of community annoyance including:
• Fear associated with noise producing activities;
• Socio-economic status and educational level;
• Perception that those affected are being unfairly treated;
• Attitudes regarding the usefulness of the noise-producing activity;
• Belief that the noise source can be controlled.
Approximately ten percent of the population has a very low tolerance for noise and will object to
any noise not of their making. Consequently, even in the quietest environment, some complaints
will occur. Another twenty-five percent of the population will not complain even in very severe
noise environments. Thus, a variety of reactions can be expected from people exposed to any
given noise environment. (8) Surveys have shown that about ten percent of the people exposed
to traffic noise of 60 dBA will report being highly annoyed with the noise, and each increase of
one dBA is associated with approximately two percent more people being highly annoyed. When
traffic noise exceeds 60 dBA or aircraft noise exceeds 55 dBA, people may begin to complain. (8)
Despite this variability in behavior on an individual level, the population can be expected to
exhibit the following responses to changes in noise levels as shown on Exhibit 2-B. An increase
or decrease of 1 dBA cannot be perceived except in carefully controlled laboratory experiments,
a change of 3 dBA are considered barely perceptible, and changes of 5 dBA are considered readily
perceptible. (6)

EXHIBIT 2-B: NOISE LEVEL INCREASE PERCEPTION
2.8 EXPOSURE TO HIGH NOISE LEVELS
The Occupational Safety and Health Administration (OSHA) sets legal limits on noise exposure in
the workplace. The permissible exposure limit (PEL) for a worker over an eight-hour day is 90
dBA. The OSHA standard uses a 5 dBA exchange rate. This means that when the noise level is
increased by 5 dBA, the amount of time a person can be exposed to a certain noise level to receive
the same dose is cut in half. The National Institute for Occupational Safety and Health (NIOSH)
has recommended that all worker exposures to noise should be controlled below a level
equivalent to 85 dBA for eight hours to minimize occupational noise induced hearing loss. NIOSH
also recommends a 3 dBA exchange rate so that every increase by 3 dBA doubles the amount of
the noise and halves the recommended amount of exposure time. (9)
OSHA has implemented requirements to protect all workers in general industry (e.g. the
manufacturing and the service sectors) for employers to implement a Hearing Conservation
Program where workers are exposed to a time weighted average noise level of 85 dBA or higher
over an eight-hour work shift. Hearing Conservation Programs require employers to measure
noise levels, provide free annual hearing exams and free hearing protection, provide training,
and conduct evaluations of the adequacy of the hearing protectors in use unless changes to tools,
equipment and schedules are made so that they are less noisy and worker exposure to noise is
less than the 85 dBA. This noise study does not evaluate the noise exposure of workers within a
project or construction site based on CEQA requirements, and instead, evaluates Project-related
operational and construction noise levels at the nearby sensitive receiver locations in the Project
study area. Further, periodic exposure to high noise levels in short duration, such as Project
construction, is typically considered an annoyance and not impactful to human health. It would
take several years of exposure to high noise levels to result in hearing impairment. (10)
2.9 VIBRATION
Per the Federal Transit Administration (FTA) Transit Noise Impact and Vibration Assessment (3),
vibration is the periodic oscillation of a medium or object. The rumbling sound caused by the
vibration of room surfaces is called structure-borne noise. Sources of ground-borne vibrations
include natural phenomena (e.g., earthquakes, volcanic eruptions, sea waves, landslides) or
human-made causes (e.g., explosions, machinery, traffic, trains, construction equipment).
Vibration sources may be continuous, such as factory machinery, or transient, such as explosions.

As is the case with airborne sound, ground-borne vibrations may be described by amplitude and
frequency.
There are several different methods that are used to quantify vibration. The peak particle
velocity (PPV) is defined as the maximum instantaneous peak of the vibration signal. The PPV is
most frequently used to describe vibration impacts to buildings, but is not always suitable for
evaluating human response (annoyance) because it takes some time for the human body to
respond to vibration signals. Instead, the human body responds to average vibration amplitude
often described as the root mean square (RMS). The RMS amplitude is defined as the average of
the squared amplitude of the signal, and is most frequently used to describe the effect of
vibration on the human body. Decibel notation (VdB) is commonly used to measure RMS.
Decibel notation (VdB) serves to reduce the range of numbers used to describe human response
to vibration. Typically, ground-borne vibration generated by man-made activities attenuates
rapidly with distance from the source of the vibration. Sensitive receivers for vibration include
structures (especially older masonry structures), people (especially residents, the elderly, and
sick), and vibration-sensitive equipment.
The background vibration-velocity level in residential areas is generally 50 VdB. Ground-borne
vibration is normally perceptible to humans at approximately 65 VdB. For most people, a
vibration-velocity level of 75 VdB is the approximate dividing line between barely perceptible and
distinctly perceptible levels. Typical outdoor sources of perceptible ground-borne vibration are
construction equipment, steel-wheeled trains, and traffic on rough roads. If a roadway is smooth,
the ground-borne vibration is rarely perceptible. The range of interest is from approximately 50
VdB, which is the typical background vibration-velocity level, to 100 VdB, which is the general
threshold where minor damage can occur in fragile buildings. Exhibit 2-C illustrates common
vibration sources and the human and structural response to ground-borne vibration.

3 REGULATORY SETTING
To limit population exposure to physically and/or psychologically damaging as well as intrusive
noise levels, the federal government, the State of California, various county governments, and
most municipalities in the state have established standards and ordinances to control noise. In
most areas, automobile and truck traffic is the major source of environmental noise. Traffic
activity generally produces an average sound level that remains constant with time. Air and rail
traffic, and commercial and industrial activities are also major sources of noise in some areas.
Federal, state, and local agencies regulate different aspects of environmental noise. Federal and
state agencies generally set noise standards for mobile sources such as aircraft and motor
vehicles, while regulation of stationary sources is left to local agencies.
3.1 STATE OF CALIFORNIA NOISE REQUIREMENTS
The State of California regulates freeway noise, sets standards for sound transmission, provides
occupational noise control criteria, identifies noise standards, and provides guidance for local
land use compatibility. State law requires that each county and city adopt a General Plan that
includes a Noise Element which is to be prepared per guidelines adopted by the Governor’s Office
of Planning and Research (OPR). (11) The purpose of the Noise Element is to limit the exposure
of the community to excessive noise levels.
3.2 CITY OF PALM DESERT GENERAL PLAN NOISE ELEMENT
The City of Palm Desert has adopted a Noise Element of the General Plan to include noise control
in the planning process. (12) The Noise Element specifies the allowable exterior noise levels for
new developments impacted by transportation noise sources such as arterial roads, freeways,
airports and railroads. In addition, the Noise Element identifies several polices to minimize the
impacts of excessive noise levels throughout the community, and establishes noise level
requirements for all land uses
3.2.1 LAND USE COMPATIBILITY
The noise criteria identified in the City of Palm Desert Noise Element (Table 7.1) are guidelines to
evaluate the land use compatibility of transportation related noise. The compatibility criteria,
shown on Exhibit 3-A, provides the City of Palm Desert with a planning tool to gauge the
compatibility of land uses relative to existing and future exterior noise levels.
The Noise Compatibility Matrix describes categories of compatibility and not specific noise
standards. Commercial land uses are considered normally acceptable with unmitigated exterior
noise levels of less than 70 dBA CNEL, and residential uses with unmitigated exterior noise levels
of less than 60 dBA CNEL. For conditionally acceptable exterior noise levels, approaching 70 dBA
CNEL for residential and 75 dBA CNEL commercial uses, new construction or development should
be undertaken only after a detailed analysis of the noise reduction requirements is made and the
needed noise insulation features are included in the design. Conventional construction, but with
closed windows and fresh air supply systems or air conditioning will normally suffice. (12)

3.3 OPERATIONAL NOISE STANDARDS
The City of Palm Desert Municipal Code, Section 9.24.030, establishes the base exterior noise
levels for receiving land uses. Exterior noise levels at residential land uses shall not exceed 55
dBA Leq during the daytime hours (7:00 a.m. to 10:00 p.m.) and 45 dBA Leq during the nighttime
hours (10:00 p.m. to 7:00 a.m.). (13) For commercial uses, exterior noise levels shall not exceed
65 dBA Leq during the daytime hours (7:00 a.m. to 10:00 p.m.) and 55 dBA Leq during the nighttime
hours (10:00 p.m. to 7:00 a.m.). The City of Palm Desert Municipal Code base exterior noise level
standards are shown on Table 3-1 and are included in Appendix 3.1.
The City of Palm Desert Municipal Code identifies base exterior noise level standards which do
not account for the existing ambient noise level. Existing ambient noise levels in the Project study
area are shown to exceed the base exterior standards at some measurement locations (described
in Table 5-1), and as such, the ambient level would become the adjusted exterior noise level
standards per Section 9.24.030(C) of the City of Palm Desert Municipal Code. However, this
analysis relies on the more restrictive base exterior noise level standards of the City of Palm
Desert Municipal Code rather than adjusted exterior noise levels which may reflect higher
existing ambient conditions.

2 Leq represents a steady state sound level containing the same total energy as a time varying signal over a given sample period.
3.4 CONSTRUCTION NOISE STANDARDS
To control noise impacts associated with the construction of the proposed Project, the City of
Palm Desert has established limits to the hours of operation. However, neither the City of Palm
Desert General Plan nor Municipal Code establish numeric maximum acceptable construction
source noise levels at potentially affected receivers, which would allow for a quantified
determination of what CEQA constitutes a substantial temporary or periodic noise increase.
To evaluate whether the Project will generate potentially significant construction noise levels at
off-site sensitive receiver locations, a construction-related noise level threshold is adopted from
the Criteria for Recommended Standard: Occupational Noise Exposure prepared by the National
Institute for Occupational Safety and Health (NIOSH). (14) A division of the U.S. Department of
Health and Human Services, NIOSH identifies a noise level threshold based on the duration of
Desert Wave Noise Impact Analysis
11826-03 Noise Study
20
exposure to the source. The construction related noise level threshold starts at 85 dBA for more
than eight hours per day, and for every 3 dBA increase, the exposure time is cut in half. This
results in noise level thresholds of 88 dBA for more than four hours per day, 92 dBA for more
than one hour per day, 96 dBA for more than 30 minutes per day, and up to 100 dBA for more
than 15 minutes per day. (14) For the purposes of this analysis, the lowest, more conservative
construction noise level threshold of 85 dBA Leq is used as an acceptable threshold for
construction noise at the nearby sensitive receiver locations. Since this construction-related
noise level threshold represents the energy average of the noise source over a given time, they
are expressed as Leq noise levels. Therefore, the noise level threshold of 85 dBA Leq over a period
of eight hours or more is used to evaluate the potential Project-related construction noise level
impacts at the nearby sensitive receiver locations.
The Occupational Safety and Health Administration (OSHA) requires hearing protection be
provided by employers in workplaces where the noise levels may, over long periods of exposure
to high noise levels, endanger the hearing of their employees. Standard 29 CFR, Part 1910
indicates the noise levels under which a hearing conservation program is required to be provided
to workers exposed to high noise levels. (9) This analysis does not evaluate the noise exposure
of construction workers within the Project site based on CEQA requirements, and instead,
evaluates the Project-related construction noise levels at the nearby sensitive receiver locations
in the Project study area. Further, periodic exposure to high noise levels in short duration, such
as Project construction, is typically considered an annoyance and not impactful to human health.
It would take several years of exposure to high noise levels to result in hearing impairment. (10)
3.5 VIBRATION STANDARDS
The City of Palm Desert does not have vibration standards for temporary construction, but the
County of Riverside’s General Plan Noise Element does contain the human reaction to typical
vibration levels. Vibration levels with peak particle velocity of 0.787 inches per second are
considered readily perceptible and above 0.1968 in/sec are considered annoying to people in
buildings. Further, County of Riverside General Plan Policy N 16.3 identifies a motion velocity
perception threshold for vibration due to passing trains of 0.01 inches per second (in/sec) over
the range of one to 100 Hz, which is used in this noise study to assess potential impacts due to
Project construction vibration levels. (12)

4 SIGNIFICANCE CRITERIA
The following significance criteria are based on currently adopted guidance provided by Appendix
G of the California Environmental Quality Act (CEQA) Guidelines. (1) For the purposes of this
report, impacts would be potentially significant if the Project results in or causes:
A. Generation of a substantial temporary or permanent increase in ambient noise levels in the
vicinity of the project in excess of standards established in the local general plan or noise
ordinance, or applicable standards of other agencies?
B. Generation of excessive ground-borne vibration or ground-borne noise levels?
C. For a project located within the vicinity of a private airstrip or an airport land use plan or, where
such a plan has not been adopted, within two miles of a public airport or public use airport, would
the project expose people residing or working in the project area to excessive noise levels?
While the City of Palm Desert General Plan Guidelines provide direction on noise compatibility
and establish noise standards by land use type that are sufficient to assess the significance of
noise impacts, they do not define the levels at which increases are considered substantial for use
under Guideline A. CEQA Appendix G Guideline C applies to nearby public and private airports,
if any, and the Project’s land use compatibility.
CEQA GUIDELINES NOT FURTHER ANALYZED
The Project site is located approximately 8.3 miles southeast of Palm Springs International
Airport, and roughly 14.7 miles northwest of Jacqueline Cochran Airport, and as such, would not
be exposed to excessive aircraft noise levels. Therefore, impacts are considered less than
significant and no further noise analysis is conducted in relation to Guideline C.
4.1 NOISE-SENSITIVE RECEIVERS
Noise level increases resulting from the Project are evaluated based on the Appendix G CEQA
Guidelines described above at the closest sensitive receiver locations. Under CEQA,
consideration must be given to the magnitude of the increase, the existing ambient noise levels,
and the location of noise-sensitive receivers to determine if a noise increase represents a
significant adverse environmental impact. This approach recognizes that there is no single noise
increase that renders the noise impact significant. (15)
Unfortunately, there is no completely satisfactory way to measure the subjective effects of noise
or of the corresponding human reactions of annoyance and dissatisfaction. This is primarily
because of the wide variation in individual thresholds of annoyance and differing individual
experiences with noise. Thus, an important way of determining a person’s subjective reaction to
a new noise is the comparison of it to the existing environment to which one has adapted—the
so-called ambient environment.
In general, the more a new noise exceeds the previously existing ambient noise level, the less
acceptable the new noise will typically be judged. The Federal Interagency Committee on Noise
(FICON) (16) developed guidance to be used for the assessment of project-generated increases
Desert Wave Noise Impact Analysis
11826-03 Noise Study
22
in noise levels that consider the ambient noise level. The FICON recommendations are based on
studies that relate aircraft noise levels to the percentage of persons highly annoyed by aircraft
noise. Although the FICON recommendations were specifically developed to assess aircraft noise
impacts, these recommendations are often used in environmental noise impact assessments
involving the use of cumulative noise exposure metrics, such as the average-daily noise level
(CNEL) and equivalent continuous noise level (Leq).
As previously stated, the approach used in this noise study recognizes that there is no single noise
increase that renders the noise impact significant, based on a 2008 California Court of Appeal
ruling on Gray v. County of Madera. (15) For example, if the ambient noise environment is quiet
(<60 dBA) and the new noise source greatly increases the noise levels, an impact may occur if the
noise criteria may be exceeded. Therefore, for this analysis, FICON identifies a readily perceptible
5 dBA or greater project-related noise level increase is considered a significant impact when the
noise criteria for a given land use is exceeded. Per the FICON, in areas where the without project
noise levels range from 60 to 65 dBA, a 3 dBA barely perceptible noise level increase appears to
be appropriate for most people. When the without project noise levels already exceed 65 dBA,
any increase in community noise louder than 1.5 dBA or greater is considered a significant impact
if the noise criteria for a given land use is exceeded, since it likely contributes to an existing noise
exposure exceedance. Table 4-1 below provides a summary of the potential noise impact
significance criteria, based on guidance from FICON.
TABLE 4-1: SIGNIFICANCE OF NOISE IMPACTS AT NOISE-SENSITIVE RECEIVERS
Without Project Noise Level Potential Significant Impact
< 60 dBA 5 dBA or more
60 - 65 dBA 3 dBA or more
> 65 dBA 1.5 dBA or more
4.2 NON-NOISE-SENSITIVE RECEIVERS
The City of Palm Desert General Plan Noise Element, Table 7.1 was used to establish the
satisfactory noise levels of significance for non-noise-sensitive land uses in the Project study area.
As previously shown on Exhibit 3-A, the normally acceptable exterior noise levels for non-noise-
sensitive land uses is 70 dBA CNEL. Noise levels greater than 70 dBA CNEL are considered
conditionally acceptable. (12)
To determine if Project-related traffic noise level increases are significant at off-site non-noise-
sensitive land uses, a readily perceptible 5 dBA and barely perceptible 3 dBA criteria were used.
When the without Project noise levels at the non-noise-sensitive land uses are below the
normally acceptable 70 dBA CNEL compatibility criteria, a readily perceptible 5 dBA or greater
noise level increase is considered a significant impact. When the without Project noise levels are
greater than the normally acceptable 70 dBA CNEL land use compatibility criteria, a barely
perceptible 3 dBA or greater noise level increase is considered a significant impact since the noise
level criteria is already exceeded. The noise level increases used to determine significant impacts
Desert Wave Noise Impact Analysis
11826-03 Noise Study
23
for non-noise-sensitive land uses is generally consistent with the FICON noise level increase
thresholds s for noise-sensitive land uses but instead rely on the City of Palm Desert General Plan
Noise Element, Table 7.1, normally acceptable 70 dBA CNEL exterior noise level criteria.
4.3 SIGNIFICANCE CRITERIA SUMMARY
Noise impacts shall be considered significant if any of the following occur as a direct result of the
proposed development. Table 4-2 shows the significance criteria summary matrix.

5 EXISTING NOISE LEVEL MEASUREMENTS
To assess the existing noise level environment, 24-hour noise level measurements were taken at
six locations in the Project study area. The receiver locations were selected to describe and
document the existing noise environment within the Project study area. Exhibit 5-A provides the
boundaries of the Project study area and the noise level measurement locations. To fully
describe the existing noise conditions, noise level measurements were collected by Urban
Crossroads, Inc. on Tuesday, January 22nd, 2019. Appendix 5.1 includes study area photos.
5.1 MEASUREMENT PROCEDURE AND CRITERIA
To describe the existing noise environment, the hourly noise levels were measured during typical
weekday conditions over a 24-hour period. By collecting individual hourly noise level
measurements, it is possible to describe the daytime and nighttime hourly noise levels and
calculate the 24-hour CNEL. The long-term noise readings were recorded using Piccolo Type 2
integrating sound level meter and dataloggers. The Piccolo sound level meters were calibrated
using a Larson-Davis calibrator, Model CAL 150. All noise meters were programmed in "slow"
mode to record noise levels in "A" weighted form. The sound level meters and microphones
were equipped with a windscreen during all measurements. All noise level measurement
equipment satisfies the American National Standards Institute (ANSI) standard specifications for
sound level meters ANSI S1.4-2014/IEC 61672-1:2013. (17)
5.2 NOISE MEASUREMENT LOCATIONS
The long-term noise level measurements were positioned as close to the nearest sensitive
receiver locations as possible to assess the existing ambient hourly noise levels surrounding the
Project site. Both Caltrans and the FTA recognize that it is not reasonable to collect noise level
measurements that can fully represent every part of a private yard, patio, deck, or balcony
normally used for human activity when estimating impacts for new development projects. This
is demonstrated in the Caltrans general site location guidelines which indicate that, sites must be
free of noise contamination by sources other than sources of interest. Avoid sites located near
sources such as barking dogs, lawnmowers, pool pumps, and air conditioners unless it is the
express intent of the analyst to measure these sources. (4) Further, FTA guidance states, that it is
not necessary nor recommended that existing noise exposure be determined by measuring at
every noise-sensitive location in the project area. Rather, the recommended approach is to
characterize the noise environment for clusters of sites based on measurements or estimates at
representative locations in the community. (3)
Based on recommendations of Caltrans and the FTA, it is not necessary to collect measurements
at each individual building or residence, because each receiver measurement represents a group
of buildings that share acoustical equivalence. (3) In other words, the area represented by the
receiver shares similar shielding, terrain, and geometric relationship to the reference noise
source. Receivers represent a location of noise sensitive areas and are used to estimate the
future noise level impacts. Collecting reference ambient noise level measurements at the nearby
sensitive receiver locations allows for a comparison of the before and after Project noise levels
Desert Wave Noise Impact Analysis
11826-03 Noise Study
26
and is necessary to assess potential noise impacts due to the Project’s contribution to the
ambient noise levels.
5.3 NOISE MEASUREMENT RESULTS
The noise measurements presented below focus on the average or equivalent sound levels (Leq).
The equivalent sound level (Leq) represents a steady state sound level containing the same total
energy as a time varying signal over a given sample period. Table 5-1 identifies the hourly
daytime (7:00 a.m. to 10:00 p.m.) and nighttime (10:00 p.m. to 7:00 a.m.) noise levels at each
noise level measurement location. Appendix 5.2 provides a summary of the existing hourly
ambient noise levels described below:
• Location L1 represents the noise levels on Portola Avenue west of the Project site, near
existing single-family residential homes. The noise level measurements collected show an
overall 24-hour exterior noise level of 71.7 dBA CNEL. The energy (logarithmic) average
daytime noise level was calculated at 69.4 dBA Leq with an average nighttime noise level of
63.4 dBA Leq.
• Location L2 represents the noise levels within The Westin Desert Willow Villas, near the
northeastern corner of the Project site boundaries. The noise level measurements collected
show an overall 24-hour exterior noise level of 53.4 dBA CNEL. The energy (logarithmic)
average daytime noise level was calculated at 49.3 dBA Leq with an average nighttime noise
level of 46.1 dBA Leq.
• Location L3 represents the noise levels on Desert Willow Drive, near the eastern boundary of
the Project site and existing golf courses. The 24-hour CNEL indicates that the overall exterior
noise level is 59.1 dBA CNEL. The energy (logarithmic) average daytime noise level was
calculated at 55.7 dBA Leq with an average nighttime noise level of 51.8 dBA Leq.
• Location L4 represents the noise levels on Desert Willow Drive, southeast of the Project site,
near Embarc Palm Desert Resort. The noise level measurements collected show an overall
24-hour exterior noise level of 55.0 dBA CNEL. The energy (logarithmic) average daytime
noise level was calculated at 49.7 dBA Leq with an average nighttime noise level of 48.2 dBA
Leq.
• Location L5 represents the noise levels on Willow Ridge within Embarc Palm Desert Resort,
south of the Project site boundaries. The 24-hour CNEL indicates that the overall exterior
noise level is 55.0 dBA CNEL. The energy (logarithmic) average daytime noise level was
calculated at 49.0 dBA Leq with an average nighttime noise level of 48.3 dBA Leq.
• Location L6 represents the noise levels on Willow Ridge, within The Westin Desert Willow
Villas Resort, near the southwestern boundary of the Project site. The noise level
measurements collected show an overall 24-hour exterior noise level of 55.2 dBA CNEL. The
energy (logarithmic) average daytime noise level was calculated at 52.3 dBA Leq with an
average nighttime noise level of 47.3 dBA Leq.

Table 5-1 provides the (energy average) noise levels used to describe the daytime and nighttime
ambient conditions. These daytime and nighttime energy average noise levels represent the
average of all hourly noise levels observed during these time periods expressed as a single
number. Appendix 5.2 provides summary worksheets of the noise levels for each hour as well as
the minimum, maximum, L1, L2, L5, L8, L25, L50, L90, L95, and L99 percentile noise levels observed
during the daytime and nighttime periods.
The background ambient noise levels in the Project study area are dominated by the
transportation-related noise associated with study area roadways in addition to background
stationary noise sources such as existing hotel and golf course activities. This includes the auto
and heavy truck activities on study area roadway segments near the noise level measurement
locations. The 24-hour existing noise level measurement results are shown on Table 5-1.

6 METHODS AND PROCEDURES
The following section outlines the methods and procedures used to model and analyze the future
traffic noise environment.
6.1 FHWA TRAFFIC NOISE PREDICTION MODEL
The expected roadway noise level increases from vehicular traffic were calculated by Urban
Crossroads, Inc. using a computer program that replicates the Federal Highway Administration
(FHWA) Traffic Noise Prediction Model- FHWA-RD-77-108. (18) The FHWA Model arrives at a
predicted noise level through a series of adjustments to the Reference Energy Mean Emission
Level (REMEL). In California the national REMELs are substituted with the California Vehicle Noise
(Calveno) Emission Levels. (19) Adjustments are then made to the REMEL to account for: the
roadway classification (e.g., collector, secondary, major or arterial), the roadway active width
(i.e., the distance between the center of the outermost travel lanes on each side of the roadway),
the total average daily traffic (ADT), the travel speed, the percentages of automobiles, medium
trucks, and heavy trucks in the traffic volume, the roadway grade, the angle of view (e.g., whether
the roadway view is blocked), the site conditions ("hard" or "soft" relates to the absorption of
the ground, pavement, or landscaping), and the percentage of total ADT which flows each hour
throughout a 24-hour period. Research conducted by Caltrans has shown that the use of soft site
conditions is appropriate for the application of the FHWA traffic noise prediction model used in
this analysis. (20)
6.2 OFF-SITE TRAFFIC NOISE PREDICTION MODEL INPUTS
Table 6-1 presents the roadway parameters used to assess the Project’s off-site transportation
noise impacts. Table 6-1 identifies the 22 study area roadway segments, the distance from the
centerline to adjacent land use based on the functional roadway classifications per the City of
Palm Desert General Plan Circulation Element, and the posted vehicle speeds. Where posted
vehicle speeds are unavailable, the 40 mph speed identified in the County of Riverside Office of
Industrial Hygiene Noise Study Guidelines is used. The ADT volumes used in this study are
presented on Table 6-2 and were obtained from the Desert Wave Traffic Impact Analysis, for the
following traffic scenarios: Existing (2019), Existing plus Ambient Growth (EA) 2022, and EA plus
Cumulative (EAC) 2022 conditions. (2)

6.3 VIBRATION ASSESSMENT
This analysis focuses on the potential ground-borne vibration associated with vehicular traffic
and construction activities. Ground-borne vibration levels from automobile traffic are generally
overshadowed by vibration generated by heavy trucks that roll over the same uneven roadway
surfaces. However, due to the rapid drop-off rate of ground-borne vibration and the short
duration of the associated events, vehicular traffic-induced ground-borne vibration is rarely
perceptible beyond the roadway right-of-way, and rarely results in vibration levels that cause
damage to buildings in the vicinity.
However, while vehicular traffic is rarely perceptible, construction has the potential to result in
varying degrees of temporary ground vibration, depending on the specific construction activities
and equipment used. Ground vibration levels associated with various types of construction
equipment are summarized on Table 6-5. Based on the representative vibration levels presented
for various construction equipment types, it is possible to estimate the human response
(annoyance) using the following vibration assessment methods defined by the FTA. To describe
the human response (annoyance) associated with vibration impacts the FTA provides the
following equation: PPVequip = PPVref x (25/D)1.5

7 OFF-SITE TRANSPORTATION NOISE IMPACTS
To assess the off-site transportation CNEL noise level impacts associated with the proposed
Project, noise contours were developed based on the Desert Wave Traffic Impact Analysis. (2)
Noise contour boundaries represent the equal levels of noise exposure and are measured in CNEL
from the center of the roadway. Noise contours were developed for the following traffic
scenarios:
• Existing (2019) Without / With Project:
o This scenario refers to the Existing present-day noise conditions, without and with the
proposed Project.
• Existing plus Ambient Growth (EA) 2022 Without / With Project:
o This scenario below refers to the background noise conditions at future Year 2022
without and with the proposed Project plus ambient growth.
• EA plus Cumulative (EAC) 2022 Without / With Project:
o This scenario below refers to the background noise conditions at future Year 2022
without and with the proposed Project plus ambient growth, and includes all
cumulative projects identified in the Traffic Impact Analysis.
7.1 TRAFFIC NOISE CONTOURS
Noise contours were used to assess the Project's incremental traffic-related noise impacts at land
uses adjacent to roadways conveying Project traffic. The noise contours represent the distance
to noise levels of a constant value and are measured from the center of the roadway for the 70,
65, and 60 dBA noise levels. The noise contours do not consider the effect of any existing noise
barriers or topography that may attenuate ambient noise levels. In addition, because the noise
contours reflect modeling of vehicular noise on area roadways, they appropriately do not reflect
noise contributions from the surrounding stationary noise sources within the Project study area.
Tables 7-1 through 7-6 present a summary of the exterior traffic noise levels, without barrier
attenuation, for the study area roadway segments analyzed from the without Project to the with
Project conditions in each of the following timeframes: Existing (2019), Existing plus Ambient
Growth (EA) 2022, and EA plus Cumulative (EAC) 2022. Appendix 7.1 includes a summary of the
traffic noise level contours for each of the traffic scenarios.

7.2 EXISTING CONDITIONS PROJECT TRAFFIC NOISE LEVEL CONTRIBUTIONS
An analysis of existing traffic noise levels plus traffic noise generated by the proposed Project has
been included in this report. However, the analysis of existing traffic noise levels plus traffic noise
generated by the proposed Project scenario will not actually occur since the Project would not
be fully constructed and operational until Year 2022 cumulative conditions.
Table 7-1 shows the Existing without Project conditions CNEL noise levels. The Existing without
Project exterior noise levels are expected to range from 64.9 to 74.2 dBA CNEL, without
accounting for any noise attenuation features such as noise barriers or topography. Table 7-2
shows the Existing with Project conditions will range from 65.2 to 74.2 dBA CNEL. Table 7-7
shows that the Project off-site traffic noise level increases will range from 0.0 to 0.4 dBA CNEL.

7.3 EA 2022 PROJECT TRAFFIC NOISE LEVEL CONTRIBUTIONS
Table 7-3 presents the Existing plus Ambient Growth (EA) without Project conditions CNEL noise
levels. The EA without Project exterior noise levels are expected to range from 64.8 to 74.4 dBA
CNEL, without accounting for any noise attenuation features such as noise barriers or

CNEL. Table 7-8 shows that the Project off-site traffic noise level increases will range from 0.0 to
0.4 dBA CNEL. Based on the significance criteria for off-site traffic noise presented in Table 4-2,
land uses adjacent to the study area roadway segments would experience less than significant
noise level impacts due to unmitigated Project-related traffic noise levels.

7.5 EIR ALTERNATIVE OFF-SITE TRAFFIC NOISE LEVELS
As a part of the Environmental Impact Report for the Project, three land use alternatives were
compared in terms of trip generation for the Project site, including: retail and multi-family
housing, single-family detached housing, and hotel use. Based on the Alternatives Trip
Generation Summary prepared by Urban Crossroads, Inc., all Project land use alternatives would
generate fewer daily trips than those of the Project. Therefore, off-site traffic noise level
increases related to the three land use alternatives are anticipated to be lower than those
presented in this report for the proposed Project land use. Moreover, since Project off-site traffic
noise level increases are shown in this report to result in less than significant noise impacts, the
three land use alternatives, which would generate fewer daily trips, would therefore, also result
in equivalent or lower off-site traffic noise level impacts.

8 SENSITIVE RECEIVER LOCATIONS
To assess the potential for long-term operational and short-term construction noise impacts, the
following sensitive receiver locations, as shown on Exhibit 8-A, were identified as representative
locations for analysis. Sensitive receivers are generally defined as locations where people reside
or where the presence of unwanted sound could otherwise adversely affect the use of the land.
Noise-sensitive land uses are generally considered to include schools, hospitals, single-family
dwellings, mobile home parks, churches, libraries, and recreation areas.
Sensitive receiver locations in the Project study area include residential uses and non-noise-
sensitive receiver locations include hotel and commercial uses, as described below. Other
sensitive land uses in the Project study area that are located at greater distances than those
identified in this noise study will experience lower noise levels than those presented in this report
due to the additional attenuation from distance and the shielding of intervening structures.
R1: Located approximately 1,306 feet west of the Project site, R1 represents existing
residential homes west of Portola Avenue. A 24-hour noise measurement was taken near
this location, L1, to describe the existing ambient noise environment.
R2: Location R2 represents the existing hotel and resort use located west of the Project site
at roughly 10 feet. A 24-hour noise measurement was taken near this location, L2, to
describe the existing ambient noise environment.
R3: Location R3 represents the existing hotel and resort use south of the Project site at
approximately 364 feet. A 24-hour noise measurement near this location, L6, is used to
describe the existing ambient noise environment.
R4: Location R4 represents the existing hotel and resort use located roughly 720 feet south
of the Project site. A 24-hour noise measurement near this location, L7, is used to
describe the existing ambient noise environment.
R5: Located approximately 1,652 feet east of the Project site, R5 represents existing
residential homes west of Cook Street. A 24-hour noise measurement was taken near
this location, L4, to describe the existing ambient noise environment.
R6: Location R6 represents the existing residential homes located north of the Project site at
roughly 1,136 feet, east of Portola Avenue. A 24-hour noise measurement was taken near
this location, L2, to describe the existing ambient noise environment.

9 OPERATIONAL NOISE IMPACTS
This section analyzes the potential stationary-source operational noise impacts at the nearby
receiver locations, identified in Section 8, resulting from operation of the proposed Desert Wave
Project. Exhibit 9-A identifies the representative receiver locations and noise source locations
used to assess the operational noise levels.
9.1 REFERENCE NOISE LEVELS
To estimate the Project operational noise impacts, reference noise level measurements were
collected from similar types of activities to represent the noise levels expected with the
development of the proposed Project. This section provides a detailed description of the
reference noise level measurements shown on Table 9-1 used to estimate the Project operational
noise impacts. It is important to note that the following projected noise levels assume the worst-
case noise environment with the surf lagoon/wave machine activities, outdoor pool/spa
activities, parking lot vehicle movements, outdoor game activities, and roof-top air conditioning
units all operating simultaneously. These noise level impacts will likely vary throughout the day.
9.1.1 SURF LAGOON/WAVE MACHINE ACTIVITY
Reference noise level measurements were provided by Wave Garden based on measurements
collected at the Wave Garden Demo Facility in Aizarnazabal, Spain in August 2017. The noise
level measurements represent the typical noise levels generated by the wave machine including
two waves at eight seconds each. The reference noise level used in this analysis is 83.6 dBA Leq
at a uniform reference distance of 50 feet. To present a conservative analysis, this noise study
assumes the surf lagoon and wave machine would operate continuously and at a constant rate
throughout both the daytime and nighttime hours, when in reality, activity is anticipated to vary
based on demand within the operational hours of 6:00 a.m. to 12:00 a.m.
9.2.2 OUTDOOR POOL/SPA ACTIVITY
To determine the noise levels associated with outdoor hotel pool and spa activity, Urban
Crossroads collected a reference noise level measurement on March 16th, 2005 at the Westin
Hotel in the City of Rancho Mirage. The measured reference noise level at 50 feet is 57.8 dBA
Leq. The outdoor pool/spa activity noise levels include a waterfall, people talking, and children
and adults swimming and playing in a pool.
9.2.3 PARKING LOT VEHICLE MOVEMENTS (AUTOS)
To determine the noise levels associated with parking lot vehicle movements, Urban Crossroads
collected a reference noise level measurement over a 24-hour period on May 17th, 2017 at the
parking lot for the Staybridge Suites in the City of Lake Forest. The peak hour of activity over the
24-hour noise level measurement period is used as the reference noise level for parking lot
vehicle movements for the purpose of this analysis. The measured reference noise level at 50
feet from parking lot vehicle movements was measured at 50.0 dBA Leq. The parking lot noise
levels are mainly due to cars pulling in and out of spaces and people talking.

11826-03 Noise Study

9.1.4 OUTDOOR GAME ACTIVITIES
To represent the potential noise level impacts associated with the Project’s outdoor game field
activities, a reference noise level measurement was collected on Wednesday, October 8th, 2014
at the Founders Park in the unincorporated community of Ladera Ranch in the County of Orange.
The reference noise levels collected at the Founders Park are expected to overestimate the noise
level activities within the outdoor fields and game areas at the Project site, since the reference
noise level measurement includes parents speaking on cell phones, kids playing, and background
youth soccer games, with coaches shouting instructions and people cheering and clapping. Using
the uniform reference distance of 50 feet, the reference playground activity noise level is 43.4
dBA Leq.
9.1.5 ROOF-TOP AIR CONDITIONING UNITS
To assess the impacts created by the roof-top air conditioning units at the Project buildings,
reference noise levels measurements were taken over a four-day total duration at the Santee
Walmart on July 27th, 2015. Located at 170 Town Center Parkway in the City of Santee, the noise
level measurements describe mechanical roof-top air conditioning units on the roof of an existing
Walmart store, in addition to background noise levels from additional roof-top units. The
reference noise level represents Lennox SCA120 series 10-ton model packaged air conditioning
units. At 5 feet from the closest roof-top air conditioning unit, the highest exterior noise level
from all four days of the measurement period was measured at 77.2 dBA Leq. Using the uniform
reference distance of 50 feet, the noise level is 57.2 dBA Leq. The operating conditions of the
reference noise level measurement reflect peak summer cooling requirements with measured
temperatures approaching 96 degrees Fahrenheit (°F) with average daytime temperatures of
82°F.
9.1.6 SPECIAL EVENTS: OUTDOOR EVENT ACTIVITY
To assess the noise impacts during outdoor special event activities, such as live or amplified
music, reference noise levels measurements were taken at a live, amplified music concert and
community event on September 19th, 2013. Located at the entrance of Clubhouse 2 of the Gate
12 Outdoor Event Space in the City of Laguna Woods, the noise level measurements describe a
community concert including a stage, sound amplifying equipment (e.g. speakers), and
unamplified crowd noise. At approximately 5 feet from the stage, the exterior noise levels were
measured at 86.8 dBA Leq. This equates to a reference noise level of 66.8 dBA Leq at 50 feet from
the noise source.

9.2 CADNAA NOISE PREDICTION MODEL
To fully describe the exterior operational noise levels from the Project, Urban Crossroads, Inc.
developed a noise prediction model using the CadnaA (Computer Aided Noise Abatement)
computer program. CadnaA can analyze the noise level of multiple types of noise sources and
calculates the noise levels at any location using the spatially accurate Project site plan and
includes the effects of topography, buildings, and multiple barriers in its calculations using the
latest standards to predict outdoor noise impacts.
Using the spatially accurate Project site plan and flown aerial imagery from Nearmap, a CadnaA
noise prediction model of the Project study area was developed. The noise model provides a
three-dimensional representation of the Project study area using the following key data inputs:
• Ground absorption;
• Multiple reflections at buildings and barriers;
• Reference noise level sources by type (area, point, etc.) and noise source height;
• Multiple noise receiver locations and heights;
• Topography and earthen berms;
• Barrier and building heights.
Desert Wave Noise Impact Analysis
11826-03 Noise Study
52
Based on these data inputs, the CadnaA noise prediction model will calculate the distance from
each noise source to the noise receiver locations, using the ground absorption, distance, and
barrier/building attenuation inputs to provide a summary of noise level calculations at each
receiver location and the partial noise level contributions by noise source. The reference sound
power level (PWL) for the highest noise source expected at the Project site was input into the
CadnaA noise prediction model. While sound pressure levels (e.g. Leq) quantify in decibels the
intensity of given sound sources at a reference distance, sound power levels (PWL) are connected
to the sound source and are independent of distance. Sound pressure levels vary substantially
with distance from the source, and also diminish as a result of intervening obstacles and barriers,
air absorption, wind, and other factors. Sound power is the acoustical energy emitted by the
sound source and is an absolute value that is not affected by the environment.
The operational noise level calculations provided in this noise study account for the distance
attenuation provided due to geometric spreading, when sound from a localized stationary source
(i.e., a point source) propagates uniformly outward in a spherical pattern. Soft site conditions
are used in the operational noise analysis which result in noise levels that attenuate (or decrease)
at a rate of 7.5 dBA for each doubling of distance from a point source, based on existing
conditions in the Project study area. Appendix 9.1 includes the CadnaA noise model inputs and
calculation data.
9.3 TYPICAL PROJECT OPERATIONAL NOISE LEVELS
As indicated on Table 9-2, the typical Project-only operational noise levels will range from 30.1
to 49.2 dBA Leq at the receiver locations. Table 9-2 also shows the operational noise levels
associated with Desert Wave Project will satisfy the City of Palm Desert base exterior noise level
standards at all nearby receiver locations.

are combined with the existing ambient noise levels measurements for the nearby receiver
locations potentially impacted by Project operational noise sources. Since the units used to
measure noise, decibels (dB), are logarithmic units, the Project-operational and existing ambient
noise levels cannot be combined using standard arithmetic equations. (4) Instead, they must be
logarithmically added using the following base equation:
Where “SPL1,” “SPL2,” etc. are equal to the sound pressure levels being combined, or in this case,
the Project-operational and existing ambient noise levels. The difference between the combined
Project and ambient noise levels describe the Project noise level contributions to the existing
ambient noise environment. Noise levels that would be experienced at receiver locations when
Project-source noise is added to the daytime and nighttime ambient conditions are presented on
Tables 9-3 and 9-4, respectively.
As indicated on Tables 9-3 and 9-4, the Project will generate unmitigated daytime operational
noise level increase of up to 3.0 dBA Leq and a nighttime operational noise level increases of up
to 4.8 dBA Leq at the nearby receiver locations, which will satisfy the significance criteria
presented in Table 4-2. Since the Project-related operational noise level contributions will satisfy
the operational noise level increase significance criteria presented in Table 4-2 under long-range
typical operational conditions, the increases at the receiver locations will be less than significant.

9.5 SPECIAL EVENT PROJECT OPERATIONAL NOISE COMPLIANCE
Project short-term special event operational noise levels are analyzed for compliance with City
of Palm Desert Municipal Code base exterior noise level limits. Special event activities within the
Project site are anticipated to include live and/or amplified music, and as such, this special event
condition analysis includes all previously analyzed typical operational noise sources, with the
addition of live and/or amplified music operating simultaneously. The special event condition
operational noise analysis shows that the unmitigated Project-related stationary-source noise
levels at all receiver locations will range from 30.1 to 49.2 dBA Leq, as shown on Table 9-5, and
will satisfy the City of Palm Desert base exterior noise level standards.

"Daytime" = 7:00 a.m. to 10:00 p.m.; "Nighttime" = 10:00 p.m. to 7:00 a.m.
Off-site parking is also proposed as part of Project special event activities, however, this analysis
focuses on the worst-case, short-term on-site Project operational activities since the live and/or
amplified music represents a new noise source in the Project study area. It is our understanding
that off-site parking would be provided in an existing parking lot area on the northwest corner of
Cook Street and Country Club Drive where an existing commercial shopping center parking lot
and vacant land exist today, and as such, off-site parking lot vehicle movements are not
anticipated to produce noise levels greater than those associated with existing ambient traffic
volumes and commercial parking and stationary-source activities under existing conditions.

10 CONSTRUCTION IMPACTS
This section analyzes potential impacts resulting from the short-term construction activities
associated with the development of the Project. Exhibit 10-A shows the construction noise
source locations in relation to the nearby sensitive receiver locations previously described in
Section 8.
10.1 CONSTRUCTION NOISE LEVELS
Noise generated by the Project construction equipment will include a combination of trucks,
power tools, concrete mixers, and portable generators that when combined can reach high
levels. The number and mix of construction equipment is expected to occur in the following
stages, based on similar projects in the City of Palm Desert:
• Site Preparation
• Grading
• Building Construction
• Architectural Coating
• Paving
This construction noise analysis was prepared using reference noise level measurements taken
by Urban Crossroads, Inc. to describe the typical construction activity noise levels for each stage
of Project construction. The construction reference noise level measurements represent a list of
typical construction activity noise levels. Noise levels generated by heavy construction
equipment can range from approximately 68 dBA to more than 80 dBA when measured at 50
feet. However, these noise levels diminish with distance from the construction site at a rate of 6
dBA per doubling of distance. For example, a noise level of 80 dBA measured at 50 feet from the
noise source to the receiver would be reduced to 74 dBA at 100 feet from the source to the
receiver, and would be further reduced to 68 dBA at 200 feet from the source to the receiver.
The construction stages and equipment are based on CalEEMod input data provided by Terran
Nova Planning & Research, Inc. (21)
10.2 CONSTRUCTION REFERENCE NOISE LEVELS
To describe the Project construction noise levels, measurements were collected for similar
activities at several construction sites. Table 10-1 provides a summary of the construction
reference noise level measurements. Since the reference noise levels were collected at varying
distances of 30 feet and 50 feet, all construction noise level measurements presented on Table
10-1 have been adjusted for consistency to describe a uniform reference distance of 50 feet.

4 Reference noise level measurements were collected from a nighttime concrete pour at an industrial construction site, located at 27334 San
Bernardino Avenue in the City of Redlands, between 1:00 a.m. to 2:00 a.m. on 7/1/15.
5 Reference noise levels are calculated at 50 feet using a drop off rate of 6 dBA per doubling of distance (point source).
10.3 CONSTRUCTION NOISE ANALYSIS
Using the reference construction equipment noise levels, calculations of the Project construction
noise level impacts at the nearby sensitive receiver locations were completed. Tables 10-2 to 10-
6 present the short-term construction noise levels for each stage of construction. Table 10-7
provides a summary of the construction noise levels by stage at the nearby noise-sensitive
receiver locations. Based on the stages of construction, the noise impacts associated with the
proposed Project are expected to create temporarily high noise levels at the nearby receiver
locations. To assess the worst-case construction noise levels, this analysis shows the highest
noise impacts when the equipment with the highest reference noise level is operating at the
closest point from the edge of primary construction activity to each receiver location.

10.4 CONSTRUCTION NOISE THRESHOLDS OF SIGNIFICANCE
The construction noise analysis shows that the highest construction noise levels will occur when
construction activities take place at the closest point from primary Project construction activity
to each of the nearby receiver locations. As shown on Table 10-7, the unmitigated construction
noise levels are expected to range from 28.5 to 68.4 dBA Leq at the nearby receiver locations.

To evaluate whether the Project will generate potentially significant short-term noise levels at
off-site sensitive receiver locations a construction-related the NIOSH noise level threshold of 85
dBA Leq is used as acceptable thresholds for construction noise at the nearby sensitive receiver
locations. Table 10-8 shows the highest construction noise levels at the potentially impacted
receiver locations are expected to approach 68.4 dBA Leq and will satisfy the NIOSH 85 dBA Leq
significance threshold during temporary Project construction activities. The noise impact due to
unmitigated Project construction noise levels is, therefore, considered a less than significant
impact at all nearby receiver locations.

10.5 CONSTRUCTION VIBRATION IMPACTS
Construction activity can result in varying degrees of ground vibration, depending on the
equipment and methods used, distance to the affected structures and soil type. It is expected
that ground-borne vibration from Project construction activities would cause only intermittent,
localized intrusion. The proposed Project’s construction activities most likely to cause vibration
impacts are:
• Heavy Construction Equipment: Although all heavy mobile construction equipment has the
potential of causing at least some perceptible vibration while operating close to buildings, the
vibration is usually short-term and is not of sufficient magnitude to cause building damage.
• Trucks: Trucks hauling building materials to construction sites can be sources of vibration
intrusion if the haul routes pass through residential neighborhoods on streets with bumps or
potholes. Repairing the bumps and potholes generally eliminates the problem.
Ground-borne vibration levels resulting from construction activities occurring within the Project
site were estimated by data published by the Federal Transit Administration. Construction
activities that would have the potential to generate low levels of ground-borne vibration within
the Project site include grading. Using the vibration source level of construction equipment
provided on Table 6-5 and the construction vibration assessment methodology published by the
FTA, it is possible to estimate the Project vibration impacts. Table 10-9 presents the expected
Project related vibration levels at the nearby receiver locations.
At distances ranging from 90 to 1,705 feet from Project construction activities, construction
vibration velocity levels are expected to approach 0.009 in/sec RMS and will remain below the
County of Riverside threshold of 0.01 in/sec RMS at all receiver locations, as shown on Table 10-
9. Therefore, the Project-related vibration impacts are considered less than significant during
the construction activities at the Project site.
Further, the Project-related construction vibration levels do not represent levels capable of
causing building damage to nearby residential homes. The FTA identifies construction vibration
levels capable of building damage ranging from 0.12 to 0.5 in/sec PPV. (3) The peak Project-
construction vibration levels shown on Table 10-9, approaching 0.013 in/sec PPV, are below the
FTA vibration levels for building damage at the residential homes near the Project site.
Moreover, the impacts at the site of the closest sensitive receivers are unlikely to be sustained
during the entire construction period, but will occur rather only during the times that heavy
construction equipment is operating adjacent to the Project site perimeter.
