1.0 Introduction
1.1 Purpose of Analysis and Study Objectives
The purpose of this noise study is to evaluate the potential noise impacts associated with
the proposed Chihuahua Tap House Limited Term Permit Application (project) and
recommend mitigation measures, if necessary, to help ensure the project complies with the
City of Newport Beach noise standards. The Limited Term Permit would allow live music/DJ
to occur indoors at the existing Chihuahua Tap House restaurant.
This report follows the City of Newport Beach Municipal Code, Chapter 10.26, Community
Noise Control standards and methodologies for analyzing noise impacts. The project shall
not create any noise, or allow the creation of any noise on the property which causes the
noise level when measured on any other property to exceed the noise standards described
in Chapter 10.26, Community Noise Control. The Newport Beach Community Noise Control
Ordinance is provided in Appendix A.
The following is provided in this report:
• A description of the study area and the proposed project
• Information regarding the fundamentals of noise
• Identification of the applicable Newport Beach noise standards
• Analysis of the existing noise environment
• Analysis of the project's operational noise impact to adjacent sensitive receptors
• Summary of recommended mitigation measures and project design features to reduce
noise level impacts.
1.2 Site Location
The project site is located at 3107 Newport Boulevard, in the City of Newport Beach. The
Chihuahua Tap House restaurant is currently operational and is located within the existing
Landing Shopping Center. The project site is zoned for Commercial Neighborhood uses.
Existing land uses surrounding the project site include; residential uses to the north, south
and west and commercial uses to the north, south and east; including restaurant and retail
uses. The nearest noise-sensitive land uses are considered the residential properties located

2.0 Fundamentals of Noise and Vibration
This section of the report provides basic information about noise and vibration and
presents some of the terms used in the report.
2.1 Sound. Noise. and Acoustics
The sound is a disturbance created by a moving or vibrating source and is capable of being
detected by the hearing organs. The sound may be thought of as mechanical energy of a
moving object transmitted by pressure waves through a medium to a human ear. For
traffic or stationary noise, the medium of concern is air. Noise is defined as sound that is
loud, unpleasant, unexpected, or unwanted.
2.2 Frequency and Hertz
A continuous sound is described by its frequency (pitch) and its amplitude (loudness).
Frequency relates to the number of pressure oscillations per second. Low-frequency sounds
are low in pitch (bass sounding) and high-frequency sounds are high in pitch (squeak).
These oscillations per second (cycles) are commonly referred to as Hertz (Hz). The human
ear can hear from the bass pitch starting out at 20 Hz all the way to the high pitch of
20,000 Hz.
2.3 Sound Pressure Levels and Decibels
The amplitude of a sound determines its loudness. The loudness of sound increases or
decreases, as the amplitude increases or decreases. Sound pressure amplitude is measured
in units of micro-Newton per square inch meter (N/m2), also called micro-Pascal (µPa).
One µPa is approximately one hundred billionths (0.00000000001) of normal atmospheric
pressure. Sound pressure level (SPL or Lp) is used to describe in logarithmic units the ratio
of actual sound pressures to a reference pressure squared. These units are called decibels
and abbreviated as dB.
2 .4 Addition of Decibels
Because decibels are on a logarithmic scale, sound pressure levels cannot be added or
subtracted by simple plus or minus addition. When two (2) sounds or equal SPL are
combined, they will produce an SPL 3 dB greater than the original single SPL.
In other words, sound energy must be doubled to produce a 3dB increase.
----------------------------r:,-,'2 engineering L.U..U group, inc.
2-1
PA2019-095
If two (2) sounds differ by approximately 1 0 dB the higher sound level is the predominant
sound.
2.5 Human Response to Changes in Noise Levels
In general, the healthy human ear is most sensitive to sounds between 1,000 Hz and
5,000 Hz, (A-weighted scale) and it perceives a sound within that range as being more
intense than a sound with a higher or lower frequency with the same magnitude. For
purposes of this report as well as with most environmental documents, the A-scale
weighing is typically reported in terms of A-weighted decibel (dBA). Typically, the human
ear can barely perceive the change in the noise level of 3 dB. A change in 5 dB is readily
perceptible, and a change in 10 dB is perceived as being twice or half as loud. As
previously discussed, a doubling of sound energy results in a 3 dB increase in sound, which
means that a doubling of sound energy (e.g. doubling the volume of traffic on a highway),
would result in a barely perceptible change in sound level.
2.6 Noise Descriptors
Noise in our daily environment fluctuates over time. Some noise levels occur in regular
patterns, others are random. Some noise levels are constant, while others are
sporadic. Noise descriptors were created to describe the different time-varying noise levels.
Following are the most commonly used noise descriptors along with brief definitions.
A-Weighted Sound Level
The sound pressure level in decibels as measured on a sound level meter using the
A-weighted filter network. The A-weighting filter de-emphasizes the very low and very
high-frequency components of the sound in a manner similar to the response of the
human ear. A numerical method of rating human judgment of loudness.
Ambient Noise Level
The composite of noise from all sources, near and far . In this context, the ambient noise
level constitutes the normal or existing level of environmental noise at a given location.

Community Noise Equivalent Level (CNEL)
The average equivalent A-weighted sound . level during a 24-hour day, obtained after
addition of f ive (5) decibels to sound levels in the evening from 7:00 to 10:00 PM and
after addition of ten (1 0) decibels to sound levels in the night before 7 :00 AM and after
10:00 PM .
Decibel (dB)
A unit for measuring the amplitude of a sound, equal to 20 times the logarithm to the
base 10 of the ratio of the pressure of the sound measured to the reference pressure,
which is 20 micro-pascals .
dB(A)
A-weighted sound level (see definition above).
Equivalent Sound Level (LEQ)
The sound level corresponding to a steady noise level over a given sample period with the
same amount of acoustic energy as the actual time-varying noise level. The energy average
noise level during the sample period.
Habitable Room
Any room meeting the requirements of the Uniform Building Code or other applicable
regulations which is intended to be used for sleeping, living, cooking or dining purposes,
excluding such enclosed spaces as closets, pantries, bath or toilet rooms, service rooms,
connecting corridors, laundries, unfinished attics, foyers, storage spaces, cellars, utility
rooms, and similar spaces.
L(n)
The A-weighted sound level exceeded during a certain percentage of the sample time. For
example, L 1 0 in the sound level exceeded 10 percent of the sample time. Similarly, LS0,
L90, and L99, etc.

Outdoor Living Area
Outdoor spaces that are associated with residential land uses typically used for passive
recreational activities or other noise-sensitive uses. Such spaces include patio areas,
barbecue areas, jacuzzi areas, etc. associated with residential uses; outdoor patient
recovery or resting areas associated with hospitals, convalescent hospitals, or rest homes;
outdoor areas associated with places of worship which have a significant role in services or
other noise-sensitive activities; and outdoor school facilities routinely used for educational
purposes which may be adversely impacted by noise. Outdoor areas usually not included
in this definition are: front yard areas, driveways, greenbelts, maintenance areas and
storage areas associated with residential land uses; exterior areas at hospitals that are not
used for patient activities; outdoor areas associated with places of worship and principally
used for short-term social gatherings; and, outdoor areas associated with school facilities
that are not typically associated with educational uses prone to adverse noise impacts (for
example, school play yard areas).

Single Event Noise Exposure Level (SENEL)
The dBA level which, if it lasted for one (1) second, would produce the same A-weighted
sound energy as the actual event.
2. 7 Sound Propagation
As sound propagates from a source it spreads geometrically. The sound from a small,
localized source (i.e., a point source) radiates uniformly outward as it travels away from the
source in a spherical pattern. The sound level attenuates at a rate of 6 dB per doubling of
distance. The movement of vehicles down a roadway makes the source of the sound
appear to propagate from a line (i.e., line source) rather than a point source. This line
source results in the noise propagating from a roadway in a cylindrical spreading versus a
spherical spreading that results from a point source. The sound level attenuates for a line
source at a rate of 3 dB per doubling of distance.
As noise propagates from the source, it is affected by the ground and atmosphere. Noise
models use the hard site (reflective surfaces) and soft site (absorptive surfaces) to help
calculate predicted noise levels. Hard site conditions assume no excessive ground
absorption between the noise source and the receiver. Soft site conditions such as grass,
soft dirt or landscaping attenuate noise at an additional rate of 1.5 dB per doubling of
distance. When added to the geometric spreading, the excess ground attenuation results in
an overall noise attenuation of 4.5 dB per doubling of distance for a line source and 6.0 dB
per doubling of distance for a point source.
Research has demonstrated that atmospheric conditions can have a significant effect on
noise levels when noise receivers are located 200 feet from a noise source. Wind,
temperature, air humidity, and turbulence can further impact how far sound can travel.
Figure 1 shows typical sound levels from indoor and outdoor noise sources.

4.0 Study Method and Procedures
The following section describes the measurement procedures, measurement locations, and
noise modeling procedures and assumptions used in the noise analysis.
4.1 Measurement Procedures and Criteria
Noise measurements are taken to determine the existing noise levels. A noise receiver or
receptor is any location in the noise analysis in which noise might produce an impact. The
following criteria are used to select measurement locations and receptors:
• Locations expected to receive the highest noise impacts, such as the first row of
houses
• Locations that are acoustically representative and equivalent of the area of concern
• Human land usage
• Sites clear of major obstruction and contamination
RK conducted the sound level measurements in accordance with Caltrans technical noise
specifications. All measurement equipment meets American National Standards Institute
(ANSI) specifications for sound level meters (S 1.4-1983 identified in Chapter
19.68.020.AA).
A Piccolo-II Type 2 sound level meter was used to conduct long term (24-hour) noise
measu rem en ts.
The Leq, Lmin, Lmax, L2, LB, L25, and LSO statistical data were recorded over the
measurement time period intervals and the information was utilized to define the noise
characteristics for the project. The following gives a brief description of the Caltrans
Technical Noise Supplement procedures for sound level measurements:
• Microphones for sound level meters were placed five (5) feet above the ground for
all short-term noise measurements and ten (1 O) feet above the ground for all long
term noise measurements.
• Sound level meters were calibrated before and after each measurement
• Following the calibration of equipment, a windscreen was placed over the
microphone
• Frequency weighting was set on "A" and slow response
• Results of the short-term noise measurements were recorded on field data sheets
-----------------------------r:,TJ engineering ~ group, inc.
4-1 ··,y11q11w r n
PA2019-095
• During any short-term noise measurements, any noise contaminations such as
barking dogs, local traffic, lawn mowers, or aircraft fly-overs were noted
• Temperature and sky conditions were observed and documented
Appendix B includes photos, field sheets, and measured noise data.
4.2 Referenced Noise Levels
To estimate future noise levels from the proposed project, referenced noise level are derived
from SoundPLAN™ software for both indoor live music and outside patio noise. Live
music/DJ noise levels are referenced at 105 dBA sound pressure level at the noise source .
Large beer garden noise has been used to model noise for the outside patio .
Indoor live music noise has been adjusted to account for the existing building enclosure
and sound barriers . All the windows and doors at Chihuahua Tap House are expected to
remain closed during live music performances, with the exception of brief periods when
doors open to allow persons to enter/exit the building.
4.3 Stationary Noise Modeling
On-site stationary noise sources were analyzed using Sound PLAN TM noise modeling
software . SoundPLAN TM is a standards-based program that incorporates more than twenty
national and international noise modeling guidelines. The following noise prediction
standards were used during the performance of this project:
• TNM 3.0 (TNM 2.5)
• FTNFRA -HSGT: 2005 (FTNFRA -HSGT;2005)
• RMR 2002 (EU-Interim) (RMR 2002)
• ISO 9613-2: 1996
• Nord2000
Projected noise levels from Sound PLAN TM are based on the following key parameters:
• Developing three -dimensional noise models of the project,
• Predicting the project noise levels at the selected community locations and
• Comparing the predicted noise with the existing community ambient noise levels at
the receptor locations .

5.0 Existing Noise Environment
The existing noise environment for the project site and surrounding areas has been
established based on noise measurement data collected by RK. Noise measurement data
indicates that traffic noise propagating from the adjacent roadways, as well as activities
from the surrounding residential and commercial land uses, are the main sources of
ambient noise at the project site and surrounding area.
Using a Piccolo-II Type 2 integrating-averaging sound level meter, one (1) 24-Hour noise
measurement was recorded at the nearest adjacent residential property line for three (3)
consecutive days on Friday, May 10th , Saturday, May 11 th , and Sunday, May 12th .
The noise monitoring locatior::i is representative of noise levels for the first row of homes
along 32 nd Street facing the project site.
The Leq, Lmin, Lmax, L2, L8, L25, and LSO statistical data were recorded on an hourly basis
over the 24-hour period. The information was utilized to define the noise characteristics for
the nearest adjacent noise sensitive land uses during daytime and nighttime hours.

The following details and observations are provided for the 24-hour noise measurement:
24-Hr Noise meter placed approximately 228 feet west of the Chihuahua Tap House,
near the residential uses along 32 nd Street. Noise meter was placed at
approximately 1 0 feet above ground level and 5 feet from the residential property
line. Ambient noise varies and includes traffic noise from 32 nd Street and Newport
Boulevard and pedestrian activity. The noise monitoring location is representative
of noise levels for the first row of homes along 32nd Street facing the project site.
The ambient noise measurement shows that existing noise levels currently exceed the
Newport Beach standards during certain times of the day and night at the residential
properties fronting along 32 nd Street. Therefore, per NBMC, Section 10.26.025, the
maximum allowable noise level during these times shall be increased to reflect the
maximum ambient noise level.
Exhibit C shows the 24-Hour noise measurement location.

6.0 Noise Impact Analysis
This assessment analyzes the change in the ambient environment as a result of operational
noise impacts generated by the project. The main sources of noise generated by the project
would include on-site stationary source noise generated by operational activities. Noise
level impacts are compared to the City of Newport Beach noise standards in the Municipal
Code. Mitigation measures are provided, as needed, to ensure the project's noise impact is
less than significant.
The project must demonstrate that noise levels generated by the project would not be in
excess of standards established in the City of Newport Beach Municipal Code, Chapter
10.26 --Community Noise Control.
6.1 Residential Noise Impacts
The potential noise impacts from the operation of the proposed restaurant to the nearest
residential land uses are analyzed. The project is requesting a Limited Term Permit to allow
live musidDJ on the premises. All live music will take place indoors. No live or amplified
music will be allowed on the patio. All the windows and doors at Chihuahua Tap House
are expected to remain closed during live music performances, with the exception of brief
periods when doors open to allow persons to enter/exit the building.
Project noise levels from live music events are combined with existing project noise levels,
including outdoor speakers and patio noise to determine the potential stationary noise
impacts to adjacent land uses.
Existing ambient noise levels are shown to currently exceed the Newport Beach Municipal
Code noise standards near the surrounding residential properties. Existing noise levels at
the surrounding residential properties are attributed to ambient conditions, including
roadway and pedestrian noise, and not specifically due to the project's existing operations.
As specified in Section 10.26.025(C) of the NBMC, in the event the ambient noise level
exceeds the noise standard, the maximum allowable noise level under said category shall
be increased to reflect the maximum ambient .noise level. NBMC also provides an allowance
for the maximum instantaneous noise levels equal to the value of the noise standard plus
twenty (20) OBA for any period of time.

As shown in Tables 3, the noise level generated by the project would be within the
allowable limits of the Newport Beach Noise Standards for both daytime and nighttime
conditions .
Furthermore, the change in the ambient environment as a result of the project is
considered less than significant. A significant increase in noise is considered to be 3 dBA
above the existing ambient environment. The 3 dBA threshold has been adopted from the
FHWA Highway Traffic Noise Analysis and Abatement Policy and Guidance document and
the Caltrans Basics of Highway Noise document, which define a 3 dBA increase as the
threshold at which the human ear can barely perceive a change in noise.
The operational noise from the proposed project is expected to be within the allowable
limits of the City of Newport Beach Municipal Code, Chapter 10 .26 --Community Noise
Control at the nearest residential properties located 220 feet away.
Stationary noise calculation worksheets are provided in Appendix C.

6.2 Summary of Analysis Results
The following findings are provided based on the results of this analysis:
1. Project noise levels are expected to be within the allowable limits of the City of
Newport Beach Exterior Noise Standards during daytime hours (7 a.m. to 10 p.m.).
2. Project noise levels are shown to be within the allowable limits of the City of
Newport Beach Exterior Noise Standards during nighttime hours (10 p.m. to 7
a.m.).
6.3 Summary of Analysis Recommendations
The following recommendations to help reduce any potential noise impacts or complaints
are provided:
1. No live music or amplified music should be played on the outdoor patio.
2. All doors and windows should remain closed (i.e ., not left open for extended
periods of time) while live music is playing.
6.4 Conclusions
RK Engineering Group, Inc. (RK) has completed a noise impact analysis for the proposed
Chihuahua Tap House Limited Term Permit Application. Based on the results and
recommendations of this analysis, indoor live music events allowed under the proposed
Limited Term Permit are not expected to result in a noise violation, as defined under the
City of Newport Beach Community Noise Control ordinance.
