Travertine Specific Plan Noise Impact Analysis
EXECUTIVE SUMMARY
Urban Crossroads, Inc. has prepared this noise study to determine the noise exposure and the
necessary noise mitigation measures for the proposed Travertine Specific Plan development
("Project"). The Project site is generally located south of the hypothetical westerly extension of
Avenue 60 and west of the hypothetical southerly extension of Madison Street in the City of La
Quinta. The proposed mixed-use Project consists of approximately 758 single family detached
residential homes, 442 duplex residential units, a 100 -room resort hotel, and other resort/golf
facilities located in Planning Area 11 (PA 11). PA 11 consists of 46.2 acres and includes the
following land uses:
• Golf Practice (4 -Holes) & Driving Range: 23.9 Acres (up to 1,000 sf of clubhouse area)
• Golf Academy: 4.7 Acres (up to 5,500 sf of indoor floor area)
• Banquet Facility & Restaurant: 4.6 Acres (up to 10,000 sf of indoor floor area)
• Slopes: 13.0 Acres (passive outdoor use)
This study has been prepared to satisfy applicable City of La Quinta noise standards and
significance criteria based on guidance provided by Appendix G of the California Environmental
Quality Act (CEQA) Guidelines. (1)
OPERATIONAL NOISE LEVELS
The Travertine Specific Plan is not expected to include any operational noise source levels beyond
those typically associated with the planned residential, resort hotel and golf course land use in
the Project study area. This includes people moving around the site, parking lot vehicle
movements, air conditioning units, play areas, etc. and is generally considered as a noise -
sensitive receiving land use. Therefore, no potential operational noise impacts for the planned
residential, resort hotel and golf course land use are analyzed in the noise study. It is expected
that the primary noise activity will be due to the Project -related off-site vehicle traffic on nearby
roadways.
SUMMARY OF CEQA SIGNIFICANCE FINDINGS
The results of this Travertine Specific Plan Noise Impact Analysis are summarized below based on
the significance criteria in Section 4 of this report consistent with Appendix G of the California
Environmental Quality Act (CEQA) Guidelines. (1) Table ES -1 shows the findings of significance
for each potential noise and/or vibration impact under CEQA before and after any required
mitigation measures described below.

Travertine Specific Plan Noise Impact Analysis
1 INTRODUCTION
This noise analysis has been completed to determine the noise impacts associated with the
development of the proposed Travertine Specific Plan ("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 short-term construction noise impacts.
1.1 SITE LOCATION
The proposed Travertine Specific Plan Project is generally located south of the hypothetical
westerly extension of Avenue 60 and west of the hypothetical southerly extension of Madison
Street in the City of La Quinta, as shown on Exhibit 1-A. Bureau of Land Management land is
located adjacent to the Project's southern boundary, Martinez Mountain is located to the
southwest, and existing residential homes are located north and east of the Project site.
1.2 PROJECT DESCRIPTION
The proposed mixed-use Project consists of approximately 758 single family detached residential
homes, 442 duplex residential units, a 100 -room resort hotel, and other resort/golf facilities
located in Planning Area 11 (PA 11). PA 11 consists of 46.2 acres and includes the following land
uses:
• Golf Practice (4 -Holes) & Driving Range: 23.9 Acres (up to 1,000 sf of clubhouse area)
• Golf Academy: 4.7 Acres (up to 5,500 sf of indoor floor area)
• Banquet Facility & Restaurant: 4.6 Acres (up to 10,000 sf of indoor floor area)
• Slopes: 13.0 Acres (passive outdoor use)
The Travertine Project is proposed to be served by two access points: 1) the southerly extension
of South Jefferson as a Modified Secondary, south of Avenue 58, and 2) the westerly extension
of Avenue 62 as a Modified Secondary, west of Monroe Street. An emergency vehicle access
(EVA) is provided via Madison Street, from the northerly boundary of the Project's Planning Area
18 to Avenue 60. Since emergency vehicle activities are exempt from the provisions of the City
of La Quinta Noise Control Ordinance (9.100.210[E]) and due to the infrequent nature of this
activity, the potential emergency vehicle noise level impacts are considered Tess than significant.

Travertine Specific Plan Noise Impact Analysis
2 FUNDAMENTALS
Noise is simply defined as "unwanted sound." Sound becomes unwanted when it interferes with
normal activities, when it causes actual physical harm or when it has adverse effects on health.
Noise is measured on a logarithmic scale of sound pressure level known as a decibel (dB). A -
weighted decibels (dBA) approximate the subjective response of the human ear to broad
frequency noise source by discriminating against very low and very high frequencies of the
audible spectrum. They are adjusted to reflect only those frequencies which are audible to the
human ear. Exhibit 2-A presents a summary of the typical noise levels and their subjective
loudness and effects that are described in more detail below.

2.1 RANGE OF NOISE
Since the range of intensities that the human ear can detect is so large, the scale frequently used
to measure intensity is a scale based on multiples of 10, the logarithmic scale. The scale for
measuring intensity is the decibel scale. Each interval of 10 decibels indicates a sound energy ten
times greater than before, which is perceived by the human ear as being roughly twice as loud.
(2) The most common sounds vary between 40 dBA (very quiet) to 100 dBA (very loud). Normal
conversation at three feet is roughly at 60 dBA, while loud jet engine noises equate to 110 dBA
12189-13_Noise Study
7
URBAN
CROSSROA DS
Travertine Specific Plan Noise Impact Analysis
at approximately 100 feet, which can cause serious discomfort. (3) Another important aspect of
noise is the duration of the sound and the way it is described and distributed in time.
2.2 NOISE DESCRIPTORS
Environmental noise descriptors are generally based on averages, rather than instantaneous,
noise levels. The most 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 (typically
one hour) 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 La Quinta relies on the 24-hour CNEL
level to assess land use compatibility with transportation related noise sources.
2.3 SOUND PROPAGATION
When sound propagates over a distance, it changes in level and frequency content. The way noise
reduces with distance depends on the following factors.
2.3.1 GEOMETRIC SPREADING
Sound from a localized source (i.e., a stationary point source) propagates uniformly outward in a
spherical pattern. The sound level attenuates (or decreases) at a rate of 6 dB for each doubling
of distance from a point source. Highways consist of several localized noise sources on a defined
path and hence can be treated as a line source, which approximates the effect of several point
sources. Noise from a line source propagates outward in a cylindrical pattern, often referred to
as cylindrical spreading. Sound levels attenuate at a rate of 3 dB for each doubling of distance
from a line source. (2)
2.3.2 GROUND ABSORPTION
The propagation path of noise from a highway to a receiver is usually very close to the ground.
Noise attenuation from ground absorption and reflective wave canceling adds to the attenuation
associated with geometric spreading. Traditionally, the excess attenuation has also been
expressed in terms of attenuation per doubling of distance. This approximation is usually
12189-13_Noise Study
8
URBAN
CROSSROA DS
Travertine Specific Plan Noise Impact Analysis
sufficiently accurate for distances of less than 200 ft. For acoustically hard sites (i.e., sites with a
reflective surface between the source and the receiver, such as a parking lot or body of water),
no excess ground attenuation is assumed. For acoustically absorptive or soft sites (i.e., those
sites with an absorptive ground surface between the source and the receiver such as soft dirt,
grass, or scattered bushes and trees), an excess ground attenuation value of 1.5 dB per doubling
of distance is normally assumed. When added to the cylindrical spreading, the excess ground
attenuation results in an overall drop-off rate of 4.5 dB per doubling of distance from a line
source. (4)
2.3.3 ATMOSPHERIC EFFECTS
Receivers located downwind from a source can be exposed to increased noise levels relative to
calm conditions, whereas locations upwind can have lowered noise levels. Sound levels can be
increased at large distances (e.g., more than 500 feet) due to atmospheric temperature inversion
(i.e., increasing temperature with elevation). Other factors such as air temperature, humidity,
and turbulence can also have significant effects. (2)
2.3.4 SHIELDING
A large object or barrier in the path between a noise source and a receiver can substantially
attenuate noise levels at the receiver. The amount of attenuation provided by shielding depends
on the size of the object and the frequency content of the noise source. Shielding by trees and
other such vegetation typically only has an "out of sight, out of mind" effect. That is, the
perception of noise impact tends to decrease when vegetation blocks the line -of -sight to nearby
residents. However, for vegetation to provide a substantial, or even noticeable, noise reduction,
the vegetation area must be at least 15 feet in height, 100 feet wide and dense enough to
completely obstruct the line -of sight between the source and the receiver. This size of vegetation
may provide up to 5 dBA of noise reduction. The FHWA does not consider the planting of
vegetation to be a noise abatement measure. (4)
2.4 NOISE CONTROL
Noise control is the process of obtaining an acceptable noise environment for an observation
point or receiver by controlling the noise source, transmission path, receiver, or all three. This
concept is known as the source -path -receiver concept. In general, noise control measures can
be applied to these three elements.
2.5 NOISE BARRIER ATTENUATION
Effective noise barriers can reduce noise levels by up to 10 to 15 dBA, cutting the loudness of
traffic noise in half. A noise barrier is most effective when placed close to the noise source or
receiver. Noise barriers, however, do have limitations. For a noise barrier to work, it must be
high enough and long enough to block the path of the noise source. (4)

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. (5)
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. 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. (6) 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. (6)
Despite this variability in behavior on an individual level, the population can be expected to
exhibit the following responses to changes in noise levels as shown on Exhibit 2-B. A change of
3 dBA is considered barely perceptible, and changes of 5 dBA are considered readily perceptible.

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. (7)
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.
2.9 VIBRATION
Per the Federal Transit Administration (FTA) Transit Noise Impact and Vibration Assessment
Manual (8), vibration is the periodic oscillation of a medium or object. The rumbling sound
caused by the vibration of room surfaces is called structure -borne noise. Sources of ground -
borne vibrations include natural phenomena (e.g., earthquakes, volcanic eruptions, sea waves,
landslides) or human -made causes (e.g., explosions, machinery, traffic, trains, construction
equipment). Vibration sources may be continuous, such as factory machinery, or transient, such
as explosions. As is the case with airborne sound, ground -borne vibrations may be described by
amplitude and frequency.

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

3 REGULATORY SETTING
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). (9) The purpose of the Noise Element is to limit the exposure of
the community to excessive noise levels. In addition, the California Environmental Quality Act
(CEQA) requires that all known environmental effects of a project be analyzed, including
environmental noise impacts.
3.2 STATE OF CALIFORNIA BUILDING STANDARDS
The State of California's noise insulation standards are codified in the California Code of
Regulations, Title 24, Building Standards Administrative Code, Part 2, and the California Building
Code. These noise standards are applied to new construction in California for the purpose of
controlling interior noise levels resulting from exterior noise sources. The regulations specify that
acoustical studies must be prepared when noise -sensitive structures, such as residential
buildings, schools, or hospitals, are developed near major transportation noise sources, and
where such noise sources create an exterior noise level of 60 dBA CNEL or higher. Acoustical
studies that accompany building plans for noise -sensitive land uses must demonstrate that the
structure has been designed to limit interior noise in habitable rooms to acceptable noise levels.
For new residential buildings, schools, and hospitals, the acceptable interior noise limit for new
construction is 45 dBA CNEL.
3.3 CITY OF LA QUINTA GENERAL PLAN ENVIRONMENTAL HAZARDS ELEMENT
The City of La Quinta has adopted an Environmental Hazards Element (Chapter 4), Noise section,
of the General Plan which identifies areas where noise levels are expected to reach unacceptable
levels, and provides policies and programs which will assure that noise levels do not negatively
impact the community. (10) The Noise Element specifies the maximum exterior and interior noise
levels for new developments impacted by transportation noise sources such as arterial roads,
12189-13_Noise Study
15
URBAN
CROSSROADS
Travertine Specific Plan Noise Impact Analysis
freeways, airports and railroads. To protect City residents from excessive noise, the
Environmental Hazards Element contains the following goal related to the Project:
N-1 A healthful noise environment which complements the City's residential and resort
character.
The noise policies specified in the City of La Quinta Environmental Hazards Element provide the
guidelines necessary to satisfy this goal. To minimize noise impacts to noise -sensitive land uses,
the City has established Policy N-1.1 to identify noise standards consistent with the Land Use
Compatibility for Community Noise Environments, Table IV -3, for various land uses. The Noise
Element also provides several policies to minimize noise impacts from transportation, such as
Policy N-1.2, which requires a noise study and any necessary mitigation measures for new
developments along roadways where the noise levels are more than 65 dBA CNEL.
The noise criteria identified in the City of La Quinta Environmental Hazards Element, Noise
section, are guidelines to evaluate the land use compatibility of transportation related noise. The
compatibility criteria, shown on Exhibit 3-A, provides the city with a planning tool to gauge the
compatibility of land uses relative to existing and future exterior noise levels.
The Land Use Compatibility for Community Noise Environments (Table IV -3) matrix in the City of
La Quinta General Plan provides guidelines to evaluate the acceptability of the transportation
related noise level impacts. Noise -sensitive land uses, such as single-family residential, are
considered normally acceptable with exterior noise levels below 60 dBA CNEL and conditionally
acceptable with noise levels below 70 dBA CNEL. Hotel land uses are considered normally
acceptable with exterior noise levels below 65 dBA CNEL and conditionally acceptable with
exterior noise levels below 70 dBA CNEL. For conditionally acceptable land use, new construction
or development should be undertaken only after a detailed analysis of the noise reduction
requirements is made and needed noise insulation features are included in the design. (10)
Based on the City of La Quinta land use compatibility guidelines and Policy N-1.2, this noise study
has been prepared to satisfy an exterior noise level of 65 dBA CNEL for residential uses, a
conditionally acceptable exterior noise level of 70 dBA CNEL for hotel uses, and an interior noise
level of less than 45 dBA CNEL for both residential and hotel uses. This approach is consistent
with Policy N-1.2 and Table IV -3 of the General Plan Environmental Hazards Element, Noise
section.

3.4 CONSTRUCTION NOISE STANDARDS
To analyze noise impacts originating from the construction of Travertine Specific Plan, noise from
construction activities are typically evaluated against standards established under a City's
Municipal Code. The Municipal Code noise standards for construction are described below for
the City of La Quinta to determine the potential noise impacts at nearby receiver locations. The
construction -related noise standards for each City are summarized in Table 3-1 below. The City
of La Quinta Municipal Code noise standards are provided in Appendix 3.1.

"n/a" = The City of La Quinta does not specify specific construction noise level standards.
To control noise impacts associated with the construction of the proposed Project, the City has
established limits to the hours of operation. The City of La Quinta Municipal Code, Section
6.08.050 indicates that construction, shall be limited to the hours of 7:00 a.m. to 5:30 p.m.
Mondays to Fridays during the months of October to April, and to the hours of 6:00 a.m. to 7:00
p.m. Mondays to Fridays during the months of May to September. All year, construction activities
are limited to 8:00 a.m. to 5:00 p.m. on Saturdays, with no activity allowed on Sundays. (11)
However, the City's General Plan and Municipal Code do not establish numeric maximum
acceptable construction source noise levels at potentially affected receivers, which would allow
for a quantified determination of what CEQA constitutes as the generation of noise levels in
excess of standards or as a substantial temporary or periodic noise increase, the following
construction noise level thresholds are used in this noise study.
3.4.1 CONSTRUCTION NOISE LEVEL COMPLIANCE THRESHOLD
To evaluate whether the Project will generate potentially significant temporary construction
noise levels at off-site sensitive receiver locations, a construction -related noise level threshold is
adopted from the Federal Transit Administration (FTA) Transit Noise and Vibration Impact
Assessment Manual. (8) According to the FTA, local noise ordinances are typically not very useful
in evaluating construction noise. They usually relate to nuisance and hours of allowed activity,
and sometimes specify limits in terms of maximum levels, but are generally not practical for
assessing the impact of a construction project. Project construction noise criteria should account
for the existing noise environment, the absolute noise levels during construction activities, the
duration of the construction, and the adjacent land use. Due to the lack of standardized
construction noise thresholds, the FTA provides guidelines that can be considered reasonable
12189-13_Noise Study
18
URBAN
CROSSROADS
Travertine Specific Plan Noise Impact Analysis
criteria for construction noise assessment. The FTA considers a daytime exterior construction
noise level of 80 dBA Leq as a reasonable threshold for noise sensitive residential land use. (8 p.
179)
3.5 CONSTRUCTION VIBRATION STANDARDS
Since the City of La Quinta does not identify specific construction vibration level standards, the
County of Riverside General Plan Noise Element Policy N 16.3 vibration standards are used in this
noise study. 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. (12) For the
purposes of this analysis, the perception threshold of 0.01 in/sec shall be used to assess the
potential impacts due to Project construction at nearby sensitive receiver locations.
Typically, the human response at the perception threshold for vibration includes annoyance in
residential areas as previously shown on Exhibit 2-C, when vibration levels expressed in vibration
decibels (VdB) approach 75 VdB. The County of Riverside, however, identifies a vibration
perception threshold of 0.01 in/sec. For vibration levels expressed in velocity, the human body
responds to the average vibration amplitude often described as the root -mean -square (RMS).
The RMS of a signal is the average of the squared amplitude of the signal, typically calculated
over a one -second period. As with airborne sound, the RMS velocity is often expressed in decibel
notation as vibration decibels (VdB), which serves to reduce the range of numbers used to
describe human response to vibration. Therefore, the County of Riverside vibration standard of
0.01 in/sec in RMS velocity levels is used in this analysis to assess the human perception of
vibration levels due to Project -related construction activities.

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 La Quinta General Plan provides direction on noise compatibility, and the City
of La Quinta Municipal Code establishes 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 project
related off-site traffic and operational noise levels are considered substantial for use under CEQA
Guideline A. Therefore, this section identifies noise level increase thresholds used to describe
the amount to which a given noise level increase is considered acceptable.
4.1 CEQA GUIDELINES NOT FURTHER ANALYZED
The Project site is located roughly 19 miles southeast of Palm Springs International Airport, and
five miles west of the Jacqueline Cochran Regional Airport. Therefore, the Project site is not
located within two miles of a public airport or the vicinity of a private airstrip, and as such, no
impact related to the exposure of people residing or working in the Project area to excessive
airport related noise levels is anticipated.
4.2 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. (13) 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.

URBAN
CROSSROADS
Travertine Specific Plan Noise Impact Analysis
4.2.1 SUBSTANTIAL PERMANENT NOISE LEVEL INCREASES
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) (14) developed guidance to be used for the assessment of project -generated increases
in noise levels that consider the ambient noise level. The FICON recommendations are based on
studies that relate aircraft noise levels to the percentage of persons highly annoyed by aircraft
noise. Although the FICON recommendations were specifically developed to assess aircraft noise
impacts, these recommendations are often used in environmental noise impact assessments
involving the use of cumulative noise exposure metrics, such as the average -daily noise level (i.e.,
CNEL).
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 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

5 dBA or more
60 - 65 dBA
3 dBA or more
> 65 dBA
1.5 dBA or more
Federal Interagency Committee on Noise (FICON), 1992.
4.2.2 SUBSTANTIAL TEMPORARY OF PERIODIC NOISE LEVEL INCREASES
Due to the temporary, short-term nature of noise -generating construction activities, the
temporary or periodic noise level increases over the existing ambient conditions must be
considered under CEQA Guideline D, consistent with the legal case, Friends of Riverside's Hills v.
Riverside Transportation Commission, et al. (15) Therefore, the Caltrans Traffic Noise Analysis
Protocol 12 dBA Leq substantial noise level increase threshold is used in this analysis to assess
temporary noise level increases. (16) If the Project -related construction noise levels generate a
temporary noise level increase above the existing ambient noise levels of up to 12 dBA Leq, then
the Project construction noise level increases will be considered a potentially significant impact.
Although the Caltrans recommendations were specifically developed to assess traffic noise
impacts, the 12 dBA Leq substantial noise level increase threshold is used in California to address
noise level increases with the potential to exceed existing conditions. (16)

Travertine Specific Plan Noise Impact Analysis
4.3 NON -NOISE -SENSITIVE RECEIVERS
To describe potential the off-site traffic noise level impacts on non -noise sensitive lands uses
adjacent to roadway segments carrying Project related traffic, this analysis has identified
thresholds of significance from the City of La Quinta General Plan. Table IV -3, Environmental
Hazards Element Noise section of the General Plan, identifies transportation -related noise level
criteria for land use compatibility. Per the City's Land Use Compatibility for Community Noise
Environments criteria, non -noise -sensitive within the industrial, manufacturing, utilities and
agricultural land use category in the Project study area are normally acceptable with exterior
noise levels approaching 70 dBA CNEL and conditionally acceptable with exterior noise levels
approaching 75 dBA CNEL. For the purposes of this noise study, non -noise sensitive land use
within the industrial, manufacturing, utilities and agricultural uses land use category are
considered normally acceptable land use with exterior noise levels below 70 dBA CNEL. (10)
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 are used.
When the without Project noise levels at the non -noise -sensitive land uses are below the 70 dBA
CNEL exterior noise level 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 70
dBA CNEL exterior noise level standard, 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 for non -noise -sensitive land uses is
generally consistent with the FICON noise level increase thresholds for noise -sensitive land uses
but instead rely on the City of La Quinta General Plan, Chapter 4, Environmental Hazards Element
Noise Section Table IV -3 exterior noise level criteria.
4.4 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, eight 24-hour noise level measurements were
taken at sensitive receiver locations in the Project study area. The receiver locations were
selected to describe and document the existing noise environment within the Project study area.
Exhibit 5-A provides the boundaries of the Project study area and the noise level measurement
locations. To fully describe the existing noise conditions, noise level measurements were
collected by Urban Crossroads, Inc. on Wednesday, August 16th, 2017. 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 any part of a private yard, patio, deck, or balcony normally
used for human activity when estimating impacts for new development projects. This is
demonstrated in the Caltrans general site location guidelines which indicate that, sites must be
free of noise contamination by sources other than sources of interest. Avoid sites located near
sources such as barking dogs, lawnmowers, pool pumps, and air conditioners unless it is the
express intent of the analyst to measure these sources. (2) Further, FTA guidance states, that it
is not necessary nor recommended that existing noise exposure be determined by measuring at
every noise -sensitive location in the project area. Rather, the recommended approach is to
characterize the noise environment for clusters of sites based on measurements or estimates at
representative locations in the community. (8)
Based on recommendations of Caltrans and the FTA, it is not necessary to collect measurements
at each individual building or residence, because each receiver measurement represents a group
of buildings that share acoustical equivalence. (8) In other words, the area represented by the
receiver shares similar shielding, terrain, and geometric relationship to the reference noise
source. Receivers represent a location of noise sensitive areas and are used to estimate the
future noise level impacts. Collecting reference ambient noise level measurements at the nearby

sensitive receiver locations allows for a comparison of the before and after Project noise levels
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

calculated at 53.2 dBA Leq with an average nighttime noise level of 53.9 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, Li, 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 the arterial roadway network. The 24-hour existing
noise level measurements shown on Table 5-1 present the existing ambient noise conditions.

6 METHODS AND PROCEDURES
The following section outlines the methods and procedures used to estimate and analyze the
future traffic noise environment. Consistent with OPR land use/noise compatibility standards,
all transportation related noise levels are presented in terms of the 24-hour CNEL's.
6.1 FHWA TRAFFIC NOISE PREDICTION MODEL
The expected roadway noise level increases from vehicular traffic were calculated by Urban
Crossroads, Inc. using a computer program that replicates the Federal Highway Administration
(FHWA) Traffic Noise Prediction Model- FHWA-RD-77-108. (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 study area roadway segments, the distance from the
centerline to adjacent land use based on the functional roadway classifications per the City of La
Quinta General Plan Circulation Element, and the posted vehicle speeds. For this analysis, soft
site conditions are used to analyze the traffic noise impacts within the Project study area. Soft
site conditions account for the sound propagation loss over natural surfaces such as normal earth
and ground vegetation. Research 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 noise
study. (20)
Consistent with Travertine Specific Plan Traffic Analysis prepared by Urban Crossroads, Inc. (21)
provides off-site roadway segment analysis for the following traffic scenarios.
• Existing Conditions
• Existing Plus Ambient Growth Plus Cumulative Projects with Project buildout (Phase 3)
• Phase 3 (2031) without Project Conditions
• Phase 3 (2031) with Project Conditions
• Year 2040 Conditions with Madison Street extension

3 provides the time of day (daytime, evening, and nighttime) vehicle splits and Table 6-4 presents
the traffic flow distributions (vehicle mix) used for this analysis. The vehicle mix provides the
hourly distribution percentages of automobile, medium trucks, and heavy trucks for input into
the FHWA noise prediction model.

7 OFF-SITE TRAFFIC NOISE IMPACTS
To assess the off-site transportation CNEL noise level impacts associated with development of
the proposed Project, noise contours were developed based on Travertine Specific Plan Traffic
Impact Analysis. (21) 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: This scenario refers to the existing present-day noise 2019 conditions, without the
proposed Project.
• Existing plus Ambient plus Cumulative (EAC) Project Phase 1 (2026): This scenario refers to the
existing plus ambient plus cumulative noise conditions at 2026 without and with the proposed
Project Phase 1. Project Phase 1 includes 530 single family detached residential homes, 74 duplex
residential units, and PA 11 resort/golf uses (golf practice, golf academy, and banquet
accommodations).
• Existing plus Ambient plus Cumulative (EAC) Project Phase 2 (2029): This scenario refers to the
existing plus ambient plus cumulative noise conditions at 2029 without and with the proposed
Project Phase 2. Project Phase 2 includes 673 single family detached residential homes, 237
duplex residential units, and PA 11 resort/golf uses (golf practice, golf academy, and banquet
accommodations).
• Existing plus Ambient plus Cumulative (EAC) Project Phase 3 (2031): This scenario refers to the
existing plus ambient plus cumulative noise conditions at 2031 without and with the proposed
Project Phase 3. Project Phase 3 includes 758 single family detached residential homes, 442
duplex residential units, a 100 -room resort hotel, and PA 11 resort/golf uses (golf practice, golf
academy, and banquet accommodations).
7.1 TRAFFIC NOISE CONTOURS
To quantify the Project's traffic noise impacts on the surrounding areas, the changes in traffic
noise levels on roadway segments surrounding the Project were calculated based on the changes
in the average daily traffic volumes. Based on the noise impact significance criteria described in
Section 4 and shown on Table 4-2, a significant off-site traffic noise level impact occurs:
• When the noise levels at existing and future noise -sensitive land uses (e.g., residential, etc.):
o are less than 60 dBA and the Project creates a readily perceptible 5 dBA or greater Project -
related noise level increase: or
o range from 60 to 65 dBA and the Project creates a barely perceptible 3 dBA or greater
Project -related noise level increase: or
o already exceed 65 dBA, and the Project creates a community noise level impact of greater
than 1.5 dBA (FICON, 1992).
• When the noise levels at existing and future non -noise -sensitive land uses (e.g., agricultural, etc.):
o are less than the City of La Quinta General Plan, Chapter 4, Environmental Hazards
Element Table IV -3 70 dBA CNEL noise level standard and the Project creates a readily
perceptible 5 dBA CNEL or greater Project -related noise level increase: or
12189-13_Noise Study

URBAN
CROSSROADS
Travertine Specific Plan Noise Impact Analysis
o are greater than the City of La Quinta General Plan, Chapter 4, Environmental Hazards
Element Table IV -3 70 dBA CNEL noise level standard and the Project creates a barely
perceptible 3 dBA CNEL or greater Project -related noise level increase.
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 include the additional barrier attenuation
provided by existing noise barriers in the Project study area. 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 7-7 present a summary of the exterior traffic noise levels, without barrier
attenuation, for the 11 study area roadway segments analyzed in the Travertine Specific Plan
Traffic Impact Analysis. (21) Appendix 7.1 includes a summary of the traffic noise level contours
for each of the following seven traffic scenarios.
• Existing Conditions
• Existing With Project (Phase 3) Conditions
• Phase 3 (2031) Without Project
• Phase 3 (2031) With Project
• Year 2040 Conditions with Madison Street extension
• Year 2040 Conditions without Madison Street extension (GPA Option 1). Consistent with
the Travertine Specific Plan Traffic Impact Analysis, this scenario includes the termination
of Madison Street as a General Plan roadway, south of Avenue 60; future Jefferson Street
connection from Avenue 58 to Avenue 62; and, emergency vehicle access (EVA) is
provided via Madison Street, from the northerly boundary of the Project's Planning Area
18 to Avenue 60.
• Year 2040 Conditions without Madison Street extension and with Project Entry Gates
(GPA Option 2). Consistent with the Travertine Specific Plan Traffic Impact Analysis, this
scenario includes the termination of Madison Street as a General Plan roadway, south of
the Avenue 60; future Jefferson Street connection from Avenue 58 to Project boundary;
the deletion of Jefferson Street as General Plan roadway south of the hypothetical
westerly extension of Avenue 60, and the deletion of Avenue 62 west of the hypothetical
southerly extension of Madison Street; on-site entry gates on Jefferson Street; Jefferson
Street is a private roadway within the Project boundary, and emergency vehicle access
(EVA) is provided via Madison Street, from the northerly boundary of the Project's
Planning Area 18 to Avenue 60.

7.2 EXISTING WITH PROJECT TRAFFIC NOISE LEVEL INCREASES
An analysis of existing off-site traffic noise levels plus traffic noise generated by the proposed
Project (Phase 3) has been included in this report. This condition is provided solely for
informational purposes and will not occur, since the Project will not be fully developed and
occupied under Existing 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 58.8
to 70.3 dBA CNEL, without accounting for any noise attenuation features such as noise barriers
or topography. Table 7-2 shows the Existing with Project (Phase 3) conditions will range from
62.2 to 72.1 dBA CNEL. Table 7-8 shows that the Project (Phase 3) off-site traffic noise level
impacts on Existing conditions will range from 1.8 to 10.2 dBA CNEL. Based on the significance
criteria for off-site traffic noise presented in Table 4-2, eight of the study area roadway segments
are shown to experience potentially significant off-site traffic noise level increases due to the
development of the full Project (Phase 3) on Existing conditions.
However, as the background ambient and cumulative traffic volumes increase, the Project's
incremental project contributions will diminish over time. By Phase 3 (2031) conditions, the off-
site traffic analysis shows that the Project's contributions to the roadway noise levels will be
reduced.

7.3 PHASE 3 (2031) PROJECT TRAFFIC NOISE LEVEL INCREASES
Table 7-9 presents a comparison of Phase 3 (2031) without and with Project conditions CNEL
noise levels. Table 7-3 shows that the exterior noise levels are expected to range from 63.5 to
75.2 dBA CNEL without the Project. Table 7-4 presents Phase 3 (2031) with Project conditions
noise level contours that are expected to range from 67.9 to 75.8 dBA CNEL. As shown on Table
7-8, the Project will generate a noise level increase ranging from 0.0 to 6.2 dBA CNEL on the study
area roadway segments. Based on the significance criteria in Section 4, the Project -related noise
level increases are considered potentially significant under Phase (2031) with Project conditions
on the following roadway segments:
• Avenue 58 west of Madison Street (Segment #1)
• Avenue 62 west of Monroe Street (Segment #6)
• Monroe Street south of Avenue 60 (Segment #8)
The three roadway segments estimated to experience potentially significant noise level impacts
due to Project -related traffic are located near the Project Site.
Avenue 58 west of Madison Street (Segment #1): This roadway segment represents the planned
southerly extension of South Jefferson south of Avenue 58 west of Madison Street near The
Quarry at La Quinta golf course. A detailed review of this roadway segment shows that the noise
sensitive residential receivers in The Quarry at La Quinta may be impacted by future Project
traffic noise from Avenue 58. However, it appears that most of these noise sensitive residential
homes benefit from an existing 6 -to -8 -foot -high berm/noise barrier. Consistent with the City of
La Quinta Noise Element, the barrier was constructed to mitigate the future long-range General
Plan Roadway network and will provide the noise attenuation needed to satisfy the 65 dBA CNEL
exterior noise requirements. Therefore, since the existing noise sensitive residential land use in
The Quarry at La Quinta were developed with the appropriate exterior noise mitigation measures
to satisfy long-range General Plan buildout traffic conditions and the Project traffic is included as
part of the General Plan, the Project related off-site traffic noise increases over time are
considered less than significant for this segment.
Avenue 62 west of Monroe Street (Segment #6): A detailed review of this roadway segment
shows that the noise sensitive Trilogy La Quinta residential community is located north of Avenue
62. This segment has the highest noise level increase since it represents the primary access to
the Project site. In combination with the low existing traffic volumes, this segment will likely
experience a potentially significant off-site traffic noise level increase of 6.2 dBA CNEL when
measured at the right-of-way of the receiving land use. However, the noise sensitive residential
homes are set back approximately 300 feet from Avenue 62 behind an existing wall. At this
distance, the exterior noise levels are estimated at 53.9 dBA CNEL and will not exceed the 65 dBA
CNEL exterior noise requirements. Consistent with the City of La Quinta Noise Element, the
nearest noise sensitive receivers within the Trilogy La Quinta residential community located
north of Avenue 62 will satisfy the 65 dBA CNEL exterior noise requirements.
Therefore, since the existing noise sensitive residential land use in Trilogy La Quinta residential
community were developed with the appropriate exterior noise mitigation measures to satisfy
12189-13_Noise Study

URBAN
CROSSROA DS
Travertine Specific Plan Noise Impact Analysis
long-range General Plan buildout traffic conditions and the Project traffic is included as part of
the General Plan, the Project related off-site traffic noise increases over time are considered less
than significant for this segment.
Monroe Street south of Avenue 60 (Segment #8): A detailed review of this roadway segment
shows that the noise sensitive Trilogy La Quinta residential community is located west of Monroe
Street. This community was developed with the benefits of a substantial 8 -foot -high noise
barrier. Consistent with the City of La Quinta Noise Element, the existing noise barrier was
constructed to mitigate the future long-range General Plan Roadway network and will provide
the noise attenuation needed to satisfy the 65 dBA CNEL exterior noise requirements. Therefore,
since the existing noise sensitive residential land use on Monroe Street south of Avenue 60 was
developed with the appropriate exterior noise mitigation measures to satisfy long-range General
Plan buildout traffic conditions and the Project traffic is included as part of the General Plan, the
Project related off-site traffic noise increases over time are considered Tess than significant.
7.4 PROJECT OFF-SITE TRAFFIC NOISE IMPACTS
The off-site traffic noise analysis recognizes that the Project would generate a noise level increase
of up to 10.2 dBA CNEL on Avenue 62 west of Monroe Street (Segment #6) when measured at
the property line of the receiving land use. The existing traffic noise levels on this segment are
calculated at 58.8 dBA CNEL. The addition of Project (Phase 3) traffic is expected to increase the
off-site traffic noise levels to 69.0 dBA CNEL resulting in a project incremental traffic noise level
increase of 10.2 dBA CNEL. According to Caltrans, a traffic impact occurs when the future noise
level substantially exceeds the existing noise level. In California a substantial noise increase is
considered to occur when the project's predicted noise level exceeds the existing noise level by
12 dBA or more. The use of 12 dB was established in California many years ago and is based on
the concept that a 10 dB increase generally is perceived as a doubling of loudness. (2 pp. 3-2)
While the relative incremental increase due to the off-site Project traffic noise on Avenue 62 west
of Monroe Street (Segment #6) may be considered a doubling of the existing traffic noise levels,
it does not exceed the Caltrans 12 dB substantial noise level increase threshold. In addition, the
Existing plus Project (Phase 3) condition is provided solely for informational purposes and will not
occur, since the Project will not be fully developed and occupied under Existing conditions. The
noise levels presented in this analysis are intended to describe the off-site traffic noise levels at
the boundary of the roadway segment right-of-way and the property line of the receiving land
use and in many cases, this does not represent the backyard of the nearest noise sensitive
receivers.

8 ON-SITE TRANSPORTATION NOISE IMPACTS
An on-site exterior noise impact analysis has been completed to determine the noise exposure
levels that would result from adjacent traffic noise sources to the noise sensitive receivers
located within the Project, and to identify potential noise abatement measures that would
achieve acceptable Project exterior and interior noise levels. Exterior noise levels are generally
limited to outdoor living areas of frequent human use (e.g., backyards of single-family homes).
Interior noise levels are evaluated at the first and second floor building facade.
The primary source of traffic noise affecting the Project site is anticipated to be from Jefferson
Street, North Loop and South Loop roadway segments. The Project will also experience some
background traffic noise impacts from other internal streets and parking lots; however, due to
the low traffic volume and low speeds of vehicles travelling on these roadways, traffic noise will
not make a significant contribution to the noise environment beyond of the right-of-way of each
road.
8.1 EXTERIOR NOISE ANALYSIS
Using the FHWA traffic noise prediction model and the parameters outlined in Tables 6-3 to 6-5,
the expected future exterior noise levels for the on-site building were calculated. Table 8-1
presents a summary of future exterior noise levels for the planned residential development
within the Travertine Specific Plan for long-range General Plan Buildout (2040) conditions. The
on-site exterior traffic noise levels indicate that the single-family residential development
adjacent to Jefferson Street, North Loop and South Loop will experience exterior noise levels
ranging from 61.2 to 62.5 dBA CNEL. Therefore, the future on-site exterior traffic noise impacts
will be less than significant. and no exterior noise abatement is needed to satisfy the City of La
Quinta 65 dBA CNEL exterior noise level standards for the proposed land uses adjacent to
Jefferson Street, North Loop or South Loop.

8.2 INTERIOR NOISE ANALYSIS
To ensure that the interior noise levels comply with the City of La Quinta interior noise level
standards, future noise levels were calculated at the first and second floor building fagade
locations.
8.2.1 NOISE REDUCTION METHODOLOGY
The interior noise level is the difference between the predicted exterior noise level at the building
facade and the noise reduction of the structure. Typical building construction will provide a Noise
Reduction (NR) of approximately 12 dBA with "windows open" and a minimum 25 dBA noise
reduction with "windows closed." (16) (4) However, sound leaks, cracks and openings within the
window assembly can greatly diminish its effectiveness in reducing noise. Several methods are
used to improve interior noise reduction, including: (1) weather-stripped solid core exterior
doors; (2) upgraded dual glazed windows; (3) mechanical ventilation/air conditioning; and (4)
exterior wall/roof assembles free of cut outs or openings.
8.2.2 INTERIOR NOISE LEVEL ASSESSMENT
Table 8-2 shows that the Project buildings will require a windows -closed condition and a means
of mechanical ventilation (e.g., air conditioning). Table 8-2 shows that the future interior noise
levels are expected to range from 36.2 to 37.5 dBA CNEL. The interior noise level analysis shows
that the City of La Quinta 45 dBA CNEL residential interior noise standards can be satisfied using
standard building construction and windows with standard STC ratings of 27 for all lots/units.
Therefore, the future on-site interior traffic noise impacts will be Tess than significant.

9 RECEIVER LOCATIONS
To assess the potential short-term construction noise impacts, the following receiver locations,
as shown on Exhibit 9-A, were identified as representative locations for analysis. Sensitive
receivers are generally defined as locations where people reside or where the presence of
unwanted sound could otherwise adversely affect the use of the land. Noise -sensitive land uses
are generally considered to include schools, hospitals, single-family dwellings, mobile home
parks, churches, libraries, and recreation areas. Moderately noise -sensitive land uses typically
include multi -family dwellings, hotels, motels, dormitories, out-patient clinics, cemeteries, golf
courses, country clubs, athletic/tennis clubs, and equestrian clubs. Land uses that are considered
relatively insensitive to noise include business, commercial, and professional developments.
Land uses that are typically not affected by noise include: industrial, manufacturing, utilities,
agriculture, undeveloped land, parking lots, warehousing, liquid and solid waste facilities, salvage
yards, and transit terminals.
To describe the potential off-site Project construction noise levels, six receiver locations in the
vicinity of the Project site were identified. All distances are measured from the Project site
boundary to the outdoor living areas (e.g., private backyards) or at the building facade, whichever
is closer to the Project site. The selection of receiver locations is based on FHWA guidelines and
is consistent with additional guidance provided by Caltrans and the FTA, as previously described
in Section 5.2. The nearest receptor where an individual can stay for a 24-hour period is
represented by R5 at approximately 1,268 feet east of the Project site boundary. Other sensitive
land uses in the Project study area that are located at greater distances than those identified in
this noise study will experience lower noise levels than those presented in this report due to the
additional attenuation from distance and the shielding of intervening structures. Distance is
measured in a straight line from the project boundary to each receiver location.
R1: Located approximately 4,517 feet north of the Project site, R1 represents existing
residential homes on Quarry Ranch Road. A 24-hour noise level measurement was taken
near this location, L1, to describe the existing ambient noise environment.
R2: Location R2 represents existing residential homes located approximately 6,872 feet north
of the Project site on Avenue 58. A 24-hour noise level measurement was taken near this
location, L2, to describe the existing ambient noise environment.
R3: Location R3 represents the existing residential homes located roughly 6,951 feet
northeast of the Project site at the southeast corner of Madison Street and Avenue 58. A
24-hour noise level measurement was taken near this location, L3, to describe the existing
ambient noise environment.
R4: Location R4 represents the existing residential homes located roughly 2,178 feet
northeast of the Project site. A 24-hour noise level measurement was taken near this
location, L8, to describe the existing ambient noise environment.
R5: Location R5 represents the existing residential community east of the Project site at
roughly 1,268 feet. A 24-hour noise level measurement was taken near this location, L7,
to describe the existing ambient noise environment.

10 CONSTRUCTION IMPACTS
This section analyzes potential off-site construction noise and vibration impacts associated with
the development of the entire Project. Exhibit 10-A shows the construction activity boundaries
in relation to the nearby off-site sensitive receiver locations.
10.1 CONSTRUCTION NOISE STANDARDS
To control noise impacts associated with the construction of the proposed Project, the City has
established limits to the hours of operation. The City of La Quinta Municipal Code, Section
6.08.050 indicates that construction, shall be limited to the hours of 7:00 a.m. to 5:30 p.m.
Mondays to Fridays during the months of October to April, and to the hours of 6:00 a.m. to 7:00
p.m. Mondays to Fridays during the months of May to September. All year, construction activities
are limited to 8:00 a.m. to 5:00 p.m. on Saturdays, with no activity allowed on Sundays. (11)
However, the City's General Plan and Municipal Code do not establish numeric maximum
acceptable construction source noise levels at potentially affected receivers, which would allow
for a quantified determination of what CEQA constitutes as the generation of noise levels in
excess of standards or as a substantial temporary or periodic noise increase, the following
construction noise level thresholds are used in this noise study. Therefore, the FTA noise level
threshold of 80 dBA Leq is used as a reasonable threshold to evaluate the potential Project -related
construction noise level impacts at the nearby sensitive receiver locations.
10.2 CONSTRUCTION ACTIVITIES
Noise generated by the Project construction equipment will include a combination of trucks,
power tools, concrete mixers, and portable generators operating simultaneously that when
combined can reach high levels. The number and mix of construction equipment are expected
to occur in the following stages:
• Site Preparation
• Grading
• Building Construction
• Paving
• Architectural Coating
10.3 TYPICAL CONSTRUCTION REFERENCE NOISE LEVELS
Noise generated by the Project construction equipment will include a combination of dozers,
graders, scrapers, trucks, power tools, rock mixers, and portable generators. Noise levels
generated by heavy construction equipment can range from approximately 68 dBA to more than
80 dBA when measured at 50 feet.

Travertine Specific Plan Noise Impact Analysis
To describe peak construction noise activities, this construction noise analysis was prepared using
reference noise level measurements published in the Update of Noise Database for Prediction of
Noise on Construction and Open Sites by the Department for Environment, Food and Rural Affairs
(DEFRA). (23). The DEFRA database provides the most recent and comprehensive source of
reference construction noise levels. Table 10-1 provides a summary of the DEFRA construction
reference noise level measurements expressed in hourly average dBA Leq using the estimated
FHWA Roadway Construction Noise Model (RCNM) usage factors (24) to describe the typical
construction activities for each stage of Project construction.

10.4 CADNAA NOISE PREDICTION MODEL
To fully describe the Project construction noise levels, Urban Crossroads, Inc. developed a noise
prediction model using the CadnaA (Computer Aided Noise Abatement) computer program.
CadnaA can analyze multiple types of noise sources using the spatially accurate Project site plan,
georeferenced Nearmap aerial imagery, topography, buildings, and barriers in its calculations to
predict outdoor noise levels. Using the ISO 9613 protocol, CadnaA will calculate the distance
from each noise source to the noise receiver locations, using the ground absorption, distance,
and barrier/building attenuation inputs to provide a summary of noise level at each receiver and
the partial noise level contributions by noise source. Consistent with the ISO 9613 protocol, the
CadnaA noise prediction model relies on the reference sound power level (Lw) to describe
individual noise sources. While sound pressure levels (e.g. Leq) quantify in decibels the intensity
12189-13_Noise Study
53
Co URBAN
Travertine Specific Plan Noise Impact Analysis
of given sound sources at a reference distance, sound power levels (Lw) are connected to the
sound source and are independent of distance. Sound pressure levels vary substantially with
distance from the source and diminish from intervening obstacles and barriers, air absorption,
wind, and other factors. Sound power is the acoustical energy emitted by the sound source and
is an absolute value that is not affected by the environment. The operational noise level
calculations provided in this noise study account for the distance attenuation provided due to
geometric spreading, when sound from a localized stationary source (i.e., a point source)
propagates uniformly outward in a spherical pattern. A default ground attenuation factor of 1.0
was used in the CadnaA noise analysis to account for soft site conditions. Appendix 9.1 includes
the detailed noise model inputs used to estimate the Project construction noise levels presented
in this section.
10.5 OFF-SITE CONSTRUCTION NOISE ANALYSIS
Using the reference construction equipment noise levels and the CadnaA noise prediction model,
calculations of the Project construction noise level impacts at the nearby off-site sensitive
receiver locations were completed. To assess the worst-case construction noise levels, the
Project construction noise analysis relies on the highest noise level impacts when the equipment
with the highest reference noise level is operating at the closest point from the edge of primary
construction activity (Project site boundary) to each of the off-site receiver location. As shown
on Table 10-2, the construction noise levels are expected to range from 28.9 to 58.7 dBA Leq, and
the highest construction levels are expected to range from 40.9 to 58.7 dBA Leq at the nearby off-
site receiver locations.

The construction noise analysis presents a conservative approach with the highest noise -level -
producing equipment for each stage of Project construction operating at the perimeter of the
Project site to the nearby sensitive receiver locations. This scenario is unlikely to occur during
typical construction activities and likely overstates the construction noise levels which will be
experienced at each receiver location.

10.6 OFF-SITE CONSTRUCTION NOISE LEVEL COMPLIANCE
To evaluate whether the Project will generate potentially significant short-term noise levels at
nearest receiver locations, a construction -related daytime noise level threshold of 80 dBA Leq is
used as a reasonable threshold to assess the daytime construction noise level impacts. The
construction noise analysis shows that the nearest off-site receiver locations will satisfy the
reasonable daytime 80 dBA Leq significance threshold during Project construction activities as
shown on Table 10-3. Therefore, the noise impacts due to Project construction noise are
considered less than significant at all off-site receiver locations.

10.7 ROCK CRUSHING REFERENCE NOISE LEVELS
An additional analysis was completed to assess the off-site construction noise level impacts due
to rock crushing activities during grading activity. No blasting is anticipated on the site. Based
on information provided by the Project Applicant, the Project will be graded in two phases (Phase
A and B) before Project infrastructure construction begins and is expected to balance. The
crushed rock will not be exported off-site and therefore no export activities are anticipated. The
type of crusher will be a mobile unit, anticipated to consist of Sandvik QJ331, Anaconda TD516,
or similar.
The rock crushing construction noise analysis was prepared using reference construction
equipment noise levels from the RCNM (25). Table 10-4 provides a summary of the reference
average Leq noise levels used to describe rock crushing construction activities that include a hoe
ram or breaker representing a percussion hammer fitted to an excavator for breaking rock.

Using the reference RCNM construction equipment noise levels shown on Table 10-4 and the
CadnaA noise prediction model, calculations of the rock crushing activity operating at the Project
site boundary to each off-site receiver location were completed. As shown on Table 10-5, the
unmitigated rock crushing noise levels are expected to range from 44.9 to 62.7 dBA Leq. The
construction noise analysis shows that the rock crushing activities will satisfy the reasonable
daytime 80 dBA Leq significance threshold at the nearest off-site receiver locations. Therefore,
the noise impacts due to Project rock crushing noise are considered less than significant at all off-
site receiver locations. Appendix 10.2 includes the rock crushing CadnaA noise model
calculations.

10.9 WATER WELL CONSTRUCTION
In addition to the on-site crushing activity, the Project will also create off-site water well
construction noise level impacts. According to the applicant, the off-site water wells will be
limited to the confined aquifer and not within 1,000 feet of any existing CVWD well site.
According to the FHWA Road Construction Noise Model, reference noise level measurements
suggest that well drilling construction noise levels approach 78 dBA Leq at 50 feet. (24) Since the
actual location of the off-site water well construction sites and potentially impacted nearby noise
sensitive receivers are not known at this time, temporary noise barriers shall be required. Prior
to water well drilling, the construction site shall provide a temporary 24 -foot -high noise barrier.
Appendix 10.3 includes photos of the planned typical temporary 24 -foot -high noise barrier used
throughout the water well construction activity. The peak off-site water well construction noise
levels with the planned temporary 24 -foot -high noise barrier at 50 feet are expected to satisfy
the reasonable daytime exterior construction noise threshold of 80 dBA Leq during temporary
Project construction activities.
10.10 OFF-SITE SUBSTATION
Electric service to Travertine will be provided by Imperial Irrigation District (IID). An offsite
substation will be required for the Travertine development and will be located and constructed
during Construction Phase I. The location of the five -acre site will be within a two-mile radius of
the project. The actual location of the substation and potentially impacted nearby noise sensitive
receivers are not known at this time. However, all substation construction noise levels shall
satisfy the reasonable daytime exterior noise threshold of 80 dBA Leq during temporary Project
construction activities.
10.11 OFF-SITE CONSTRUCTION NOISE LEVEL INCREASES
To describe the off-site Project construction noise level contributions to the existing ambient
noise environment, the Project construction noise levels were combined with the existing
ambient noise levels measurements at the off-site receiver locations. The difference between
the combined Project -construction and ambient noise levels are used to describe the
construction noise level contributions. Temporary noise level increases that would be
experienced at sensitive receiver locations when Project construction -source noise is added to
the ambient daytime conditions are presented on Table 10-6. A temporary noise level increase
of 12 dBA is considered a potentially significant impact based on the Caltrans substantial noise
level increase criteria which is used to assess the Project -construction noise level increases. (16)
No nighttime construction activity is permitted in the City of La Quinta Municipal Code, and
therefore, nighttime noise level increases are not analyzed in this noise study.
As indicated in Table 10-6, the Project will contribute unmitigated, typical construction noise level
increases at nearby sensitive residential homes of up to 11.6 dBA Leq during the daytime hours.
Since the highest temporary noise level increase of up to 11.6 dBA Leq during Project construction
will satisfy the 12 dBA Leq significance threshold, the unmitigated construction noise level
increases are considered Tess than significant temporary noise impacts.

10.12 ON-SITE CONSTRUCTION NOISE ANALYSIS
Due to the phased nature of the Project development, future phases have the potential to
generate construction noise level impacts to previous phases of development. The project
grading will take place in two phases. Phase A will grade the southern half of the project and
Phase B grading will grade the northern half of the project. Phase B grading will impact the on-
site noise sensitive residential land uses planned in Phase 1A as shown on Exhibit 10-B. To assess
the potential Phase B grading construction noise source activity, receiver locations were
identified within in each of the Phase 1A Planning Areas to describe the on-site construction noise
level impacts.
Table 10-7 shows that the highest construction Phase B on-site Project grading construction of
noise levels are expected to range from 68.0 to 72.5 dBA Leq and will satisfy the reasonable
daytime 80 dBA Leq significance threshold. Therefore, the noise impacts due to the Phase B
grading construction noise source activities are considered Tess than significant at all the nearest
on-site receiver locations.

10.13 OFF-SITE 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. Ground -borne vibration levels resulting from typical construction activities
occurring within the Project site were estimated by data published by the Federal Transit
Administration (FTA). (8) However, while vehicular traffic is rarely perceptible, construction has

CR055ROAD5

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 9-11. Based on the
representative vibration levels presented for various construction equipment types, it is possible
to estimate the potential Project construction vibration levels 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

Source: Federal Transit Administration, Transit Noise and Vibration Impact Assessment Manual
Using the vibration source level of construction equipment provided on Table 10-11 and the
construction vibration assessment methodology published by the FTA, it is possible to estimate
the Project vibration impacts. Table 10-12 presents the expected Project related vibration levels
at the nearby receiver locations. At distances ranging from 1,268 to 6,9518 feet from Project
construction activities, construction vibration velocity levels are estimated to range from 0.0000
to 0.0002 in/sec RMS and will remain below the City of La Quinta threshold of 0.01 in/sec RMS
at all receiver locations, as shown on Table 10-12. The analysis shows that at 90 feet from the
construction vibration source activities, receivers would experience vibration velocity level of
0.0093 in/sec RMS. Therefore, vibration levels are considered Tess than significant any receiver
located at distances of greater than 90 from construction equipment.
Further, the levels 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. Construction at the Project site
will be restricted to daytime hours consistent with City requirements thereby eliminating
potential vibration impact during the sensitive nighttime hours.

10.14 CONSTRUCTION NOISE AND VIBRATION ABATEMENT MEASURES
Though construction noise is temporary, intermittent and of short duration, and will not present
any long-term impacts, the following abatement measures would reduce any noise level
increases produced by the construction equipment to the nearby noise -sensitive residential land
uses:
• Prior to approval of grading plans and/or issuance of building permits, plans shall include a note
indicating that noise -generating Project construction activities shall only occur between the hours
of 7:00 a.m. to 5:30 p.m. Mondays to Fridays during the months of October to April, and to the
hours of 6:00 a.m. to 7:00 p.m. Mondays to Fridays during the months of May to September. All
year, construction activities are limited to 8:00 a.m. to 5:00 p.m. on Saturdays, with no activity
allowed on Sundays. (11) The Project construction supervisor shall ensure compliance with the
note and the City shall conduct periodic inspection at its discretion.
• During all Project site construction, the construction contractors shall equip all construction
equipment, fixed or mobile, with properly operating and maintained mufflers, consistent with
manufacturers' standards. The construction contractor shall place all stationary construction
equipment so that emitted noise is directed away from the noise sensitive receptors nearest the
Project site.
• The construction contractor shall locate equipment staging in areas that will create the greatest
distance between construction -related noise sources and noise -sensitive receivers nearest the
Project site during all Project construction (i.e., to the west).
• The construction contractor shall limit construction haul truck deliveries to the same hours
specified for construction equipment (between the hours of 7:00 a.m. to 5:30 p.m. Mondays to
Fridays during the months of October to April, and to the hours of 6:00 a.m. to 7:00 p.m. Mondays
to Fridays during the months of May to September. All year, construction activities are limited to
8:00 a.m. to 5:00 p.m. on Saturdays, with no activity allowed on Sundays (11)). The contractor
shall design delivery routes to minimize the exposure of sensitive land uses or residential
dwellings to delivery truck -related noise.
