Summary
The City of Santa Ana (City), in conjunction with the California Department of
Transportation (Caltrans), District 12, proposes to widen Fairview Street between 9th
Street and 16th Street, including replacing the Fairview Street bridge crossing over
the Santa Ana River (proposed Project) in Santa Ana, California. The purpose of the
project is to reduce congestion and improve pedestrian and bicyclist safety on
Fairview Street between 9th Street and 16th Street, consistent with the Orange
County Master Plan of Arterial Highways and the City's General Plan Circulation
Element.
South of 9th Street, Fairview Street provides three lanes in each direction, which are
reduced to two lanes in each direction north of 9th Street, across the existing four -
lane bridge, to 16th Street. The Fairview Street segment between 9th Street and 16th
Street is the only constraint for Fairview Street to be built out to its planned width of
six lanes. This condition causes a traffic "bottleneck" during peak hours. In addition,
there are no sidewalks, bikeways, or lighting on the existing bridge. Pedestrians and
bicyclists currently use the roadway shoulder to cross the bridge.
A Type 1 project, as defined by Title 23, Part 772, of the Code of Federal Regulations
(23 CFR 772), is any proposed Federal or Federal -aid highway project for the
construction of a highway on new location, the physical alteration of an existing
highway where there is either substantial horizontal or vertical alignment alteration,
or other activities listed as a Type 1 project. The proposed Project is considered a
Type 1 project because one additional travel lane in each direction would be added on
Fairview Street. A noise analysis is required for all Type 1 projects.
Existing land uses in the project area include single-family and multifamily
residences, a medical office, a park (Fairview Triangle Habitat Restoration Park), a
multi -use trail, vacant land, and office, commercial, and light industrial uses. The
primary source of noise in the project area is traffic on Fairview Street.
The terrain in the project area can be separated into four areas:
• Land uses east of Fairview Street and south of the Santa Ana River include single-
family and multifamily residences, vacant land, and commercial uses that range
from 3 feet (ft) higher to 7 ft lower in elevation than Fairview Street.
Fairview Street Improvements from 9th Street to 16th Street
and Bridge Replacement Project Noise Study Report
• Land uses west of Fairview Street and south of the Santa Ana River include
single-family and multifamily residences, a medical office, a park, a trail, and
office uses that range from 2 ft higher to 5 ft lower in elevation than Fairview
Street.
• Land uses east of Fairview Street and north of the Santa Ana River include single-
family residences and commercial and light industrial uses that range from 2 ft
higher in elevation than Fairview Street to approximately the same elevation as
Fairview Street.
• Land uses west of Fairview Street and north of the Santa Ana River include
single-family residences, vacant land, and commercial and light industrial uses
that range from 2 ft higher to 9 ft lower in elevation than Fairview Street.
Fifteen short-term noise level measurements were conducted at representative
locations to document the existing noise environment. All short-term noise level
measurements were used to calibrate the Federal Highway Administration (FHWA)
Traffic Noise Model (TNM) 2.5 (2004) with concurrent traffic counts and observed
vehicle speeds to ensure the accuracy of TNM 2.5. A total of 92 representative
existing receptors were modeled and evaluated for potential noise impacts resulting
from traffic noise. The results of the modeled noise levels for Existing, Future No
Build, and Future Build conditions are provided in Table B.1 in Appendix B.
Two long-term (24-hour) noise level measurements were conducted in the project
area to characterize the change in hourly noise levels over the course of a 24-hour
period in the project area and to identify the peak traffic noise hour.
When traffic noise impacts have been identified, noise abatement measures must be
considered. Traffic noise impacts result from one or more of the following
occurrences: (1) an increase of 12 A -weighted decibels (dBA) or more over the
corresponding existing noise levels, or (2) predicted noise levels approaching or
exceeding the Noise Abatement Criteria (NAC).
Implementation of the proposed Project would result in potential short-term noise
impacts during construction and long-term operational noise impacts from use of the
completed project. Of the 92 modeled receptors, nine receptors would approach or
exceed the NAC. No modeled receptors would experience a substantial increase of
12 dBA or more over their corresponding modeled existing noise levels.
Noise abatement measures were evaluated for receptors within the project limits that
would be or would continue to be exposed to traffic noise levels approaching or

exceeding the NAC. Six noise barriers were evaluated. The results of the noise barrier
modeling are shown in Table B.1 in Appendix B. All six noise barriers were capable
of reducing noise levels by 5 dBA or more, as required to be considered feasible.
A Noise Abatement Decision Report (NADR) will be prepared for the proposed
Project. The NADR is a design responsibility and is prepared to compile information
from the Noise Study Report (NSR), other relevant environmental studies, and design
considerations into a single, comprehensive document before public review of the
proposed Project. The NADR is prepared after completion of the NSR and prior to
publication of the draft environmental document. The NADR includes noise
abatement construction cost estimates that have been prepared and signed by the
project engineer based on site -specific conditions. Construction cost estimates are
compared to reasonable allowances in the NADR to identify which noise barrier
configurations are reasonable from a cost perspective. The reasonableness
determination of the feasible noise barriers shown in Tables 7.1 through 7.6 will be
reported in the NADR for the proposed Project.
The design of noise barriers presented in this report is preliminary and has been
conducted at a level appropriate for environmental review and not for final design of
the proposed Project. If pertinent parameters change substantially during the final
project design, preliminary noise barrier designs may be modified or eliminated from
the final project. A final decision on the construction of the noise abatement will be
made upon completion of the public involvement process during the final project
design process.
The closest residences are located approximately 50 ft from the project construction
areas. Therefore, the closest residences may be subject to short-term noise reaching
88 dBA maximum instantaneous noise level (Lmax) or higher generated by
construction activities in the project area. Compliance with the Caltrans Standard
Specifications, Section 14-8.02, and the City's Municipal Code, Section 18-314, will
be required to minimize construction noise impacts on land uses adjacent to the
project area. In compliance with these regulations, the contractor shall not perform
any construction activities between the hours of 8:00 p.m. and 7:00 a.m. on weekdays
and Saturdays, or at any time on Sundays and federal holidays.

Chapter 1. Introduction
The City of Santa Ana (City), in conjunction with the California Department of
Transportation (Caltrans) District 12, proposes to widen Fairview Street between 9th
Street and 16th Street, including replacing the Fairview Street bridge crossing over
the Santa Ana River (proposed Project) in Santa Ana, California. The purpose of the
project is to reduce congestion and improve pedestrian and bicyclist safety on
Fairview Street between 9th Street and 16th Street, consistent with the Orange
County Master Plan of Arterial Highways and the City's General Plan Circulation
Element.
South of 9th Street, Fairview Street provides three lanes in each direction which are
reduced to two lanes in each direction north of 9th Street, across the existing four -
lane bridge, to 16th Street. The Fairview Street segment between 9th Street and 16th
Street is the only constraint for Fairview Street to be built out to its planned width of
six lanes. This condition causes a traffic "bottleneck" during peak hours. In addition,
there are no sidewalks, bikeways, or lighting on the existing bridge. Pedestrians and
bicyclists currently use the roadway shoulder to cross the bridge.
Within the project limits, Fairview Street is bordered by single-family residences and
a few commercial properties.
1.1. Purpose of the Noise Study Report
The purpose of Title 23, Part 772, of the Code of Federal Regulations (23 CFR 772),
"Procedures for Abatement of Highway Traffic Noise and Construction Noise,"
(1982) is to provide procedures to help protect public health and welfare, supply
Noise Abatement Criteria (NAC), and establish requirements for information to be
given to local officials for use in the planning and design of highways approved
pursuant to 23 CFR 772.1. As such, 23 CFR 772 provides procedures for preparing
operational and construction noise impact studies and evaluating noise abatement
considered for federal and federal -aid highway projects. According to 23 CFR 772.3,
all highway projects that are developed in conformance with this regulation are
deemed to be in conformance with Federal Highway Administration (FHWA) noise
standards.
Fairview Street Improvements from 9th Street to 16th Street
and Bridge Replacement Project Noise Study Report
ter 1. Introduction
The Caltrans Traffic Noise Analysis Protocol for New Highway Construction,
Reconstruction, and Retrofit Barrier Projects (Protocol) (Caltrans 2011) provides
Caltrans policy for implementing 23 CFR 772 in California. The Protocol outlines the
requirements for preparing Noise Study Reports (NSRs). The purpose of this NSR is
to evaluate noise impacts and noise abatement consistent with the requirements of
23 CFR 772.
1.2. Project Purpose and Need
The Project Area has a history of traffic congestion; however, the proposed Project
would improve traffic flow and alleviate congestion in this area. The proposed Project
would also increase pedestrian safety at Fairview Street bridge by constructing new
barrier rails, sidewalks, bicycle lanes, a raised median, and lighting on the proposed
bridge structure.
1.2.1. Project Purpose
The purpose of the proposed Project is to improve pedestrian/bicyclist safety and
traffic flow on and in the vicinity of Fairview Street bridge. The following goals/
objectives have been identified for the proposed Project:
• Provide for adequate vehicular capacity and greater pedestrian and bike safety on
Fairview Street bridge; and
• Make the Fairview Street bridge design and capacity consistent with the Orange
County Master Plan of Arterial Highways and the City of Santa Ana General Plan
Circulation Element.
1.2.2. Project Need
The existing Fairview Street bridge has insufficient safety barriers and capacity to
handle existing and projected traffic levels in the Project Area and is operating with
the following deficiencies within the Project limits:
• No sidewalks, bike lanes, center median or barrier, or lighting; and
• Congestion on and around the existing bridge due to high traffic demands and a
limited number of lanes relative to areas north and south of the bridge.
2 Fairview Street Improvements from 9th Street to 16th Street
and Bridge Replacement Project Noise Study Report
Chapter 2. Project Description
The City, in conjunction with Caltrans District 12, proposes to replace the Fairview
Street bridge over the Santa Ana River and widen Fairview Street between 9th Street
and 16th Street in Santa Ana, California. The City is the lead agency under the
California Environmental Quality Act (CEQA). Caltrans is the lead agency under the
National Environmental Policy Act (NEPA), as assigned by the FHWA through
NEPA Delegation.
This section describes the proposed Project and the alternatives that were developed
to meet the identified purpose and need of the proposed Project while avoiding or
minimizing environmental impacts. The two alternatives being evaluated are the
No Build Alternative and the Build Alternative.
2.1. No Build Alternative
The No Build Alternative assumes that no improvements are made to Fairview Street.
The No Build Alternative would maintain the existing conditions and provides a
baseline for comparison of the impacts under the Build Alternative. Under the No
Build Alternative, the performance of the roadway would continue to deteriorate with
the forecasted increase in traffic.
2.2. Build Alternative
The proposed Project includes widening Fairview Street between 9th Street and 16th
Street, including replacing the Fairview Street bridge crossing over the Santa Ana
River. The proposed Project would widen Fairview Street from two lanes in each
direction to three lanes in each direction, as shown in Figures 2-1 and 2-2. Fairview
Street bridge would be replaced with a new six -lane bridge (three lanes in each
direction), including a complete bridge deck with barrier rails, sidewalks, bicycle
lanes, a raised median, and lighting.
The proposed bridge would be expanded from approximately 52 feet (ft) to 100 ft in
width, and would have the same roadway profile as the existing bridge. The eight pier
walls that support the existing bridge would be removed, and four new pier walls
would be constructed to support the new bridge.

The proposed Project would partial acquire right-of-way take from three parcels (two
commercial parcels [Assessor's Parcel Numbers (APNs) 405-213-02 and 405-213-01]
and one single-family residence [APN 405-213-14]), as shown in Figure 2-2.
An existing 12-inch water line and a bank of 12 phone conduits cross the Santa Ana
River, suspended under the deck of the existing bridge. These utilities would need to
be temporarily relocated during construction and then permanently relocated to the
new bridge.
Water quality best management practices (BMPs) would be included to treat
stormwater runoff such as a vegetated swale adjacent to Fairview Street in the
Fairview Triangle rest area.
Fairview Street would remain open during the construction period with two
nouhbound lanes and one northbound lane, with lanes shifted to one side of the
bridge while the other side is replaced. Therefore, no detours would be required for
vehicles traveling along Fairview Street. Access to properties would be maintained.
During construction, pedestrians and bikes would be detoured away from the
Fairview Street bridge to the 17th Street Bridge to cross the Santa Ana River by way
of the Santa Ana River Trail (SART) between the hours of 9:00 a.m. and 7:00 p.m.,
when the gates to the SART are open and unlocked. After hours, pedestrians and
bicyclists who wish to cross the Santa Ana River would be detoured to adjacent City
streets such as King Street.
Construction of the proposed Project would require temporary closure of a portion of
the SART for the demolition and placement of the bridge superstructure. The SART
includes a Class I bike path on the eastern side and a regional riding and hiking trail
on the western side. The portion of the SART affected by project construction would
need to be temporarily closed four times for approximately 8 hours each time during
two summer periods for the placement of precast concrete girders. During these
periods, SART users would be detoured and signage would be provided to display the
dates of the closures and to identify the detour routes. Work on the north and south
sides of the bridge would be completed during separate periods so that SART users
can be detoured to the trail on the opposite side of the Santa Ana River at 5th Street.
There are gates and ramps located on both sides of the SART at 5th Street that
provide access to bicyclists and pedestrians for these detours. Details regarding the
detours are being coordinated with Orange County Parks. Other short-term closures
of up to 15 minutes would be allowed with flagmen.

Chapter 2. Project Description
A temporary detour within the river bed may be required as a contingency. This
would involve construction of dirt and gravel ramps with asphalt topping to and from
the SART and the river bed.
Construction vehicles would access the Santa Ana River from the gate and ramp at
the County of Orange access road at the northwest corner of the bridge, and would
use the existing concrete access ramp into the river approximately 250 ft west of the
Project Area .All access roads to the SART that are utilized by construction vehicles
or for detour routes would be reconstructed and restored to pre -construction
conditions or better prior to project completion.

Chapter 3. Fundamentals of Traffic Noise
The following is a brief discussion of fundamental traffic noise concepts. For a
detailed discussion, refer to the Caltrans Technical Noise Supplement (TeNS), a
technical supplement to the Protocol that is available on the Caltrans website
(Caltrans 2013).
3.1. Sound, Noise, and Acoustics
Sound can be described as the mechanical energy of a vibrating object transmitted by
pressure waves through a liquid or gaseous medium (e.g., air) to a hearing organ
(e.g., a human ear). Noise is defined as loud, unexpected, or annoying sound.
In the science of acoustics, the fundamental model consists of a sound (or noise)
source, a receptor, and the propagation path between the two. The loudness of the
noise source and obstructions or atmospheric factors affecting the propagation path to
the receptor determine the sound level and characteristics of the noise perceived by
the receptor. The field of acoustics deals primarily with the propagation and control
of sound.
3.2. Frequency and Hertz
Continuous sound can be described by frequency (pitch) and amplitude (loudness).
A low -frequency sound is perceived as low in pitch. Frequency is expressed in terms
of cycles per second, or Hertz (Hz) (e.g., a frequency of 250 cycles per second is
referred to as 250 Hz). High frequencies are sometimes more conveniently expressed
in kilohertz (kHz), or thousands of Hertz. The audible frequency range for humans is
generally between 20 Hz and 20,000 Hz.
3.3. Sound Pressure Levels and Decibels
The amplitude of pressure waves generated by a sound source determines the
loudness of that source. Sound pressure amplitude is measured in micropascals (µPa).
One µPa is approximately one hundred billionths (0.00000000001) of the normal
atmospheric pressure. Sound pressure amplitudes for different kinds of noise
environments can range from less than 100 to 100,000,000 µPa. Because of this huge
range of values, sound is rarely expressed in terms of µPa. Instead, a logarithmic
scale is used to describe sound pressure level (SPL) in terms of decibels (dB).
Fairview Street Improvements from 9th Street to 16th Street 11
and Bridge Replacement Project Noise Study Report
3. Fundamentals of Traffic Noise
The threshold of hearing for young people is approximately 0 dB, which corresponds
to 20 [Pa.
3.4. Addition of Decibels
Because decibels are logarithmic units, SPL cannot be added or subtracted through
ordinary arithmetic. Under the decibel scale, a doubling of sound energy corresponds
to a 3 dB increase. In other words, when two identical sources are each producing
sounds of the same loudness, the resulting sound level at a given distance would be
3 dB higher than one source under the same conditions. For example, if one
automobile produces an SPL of 70 dB when it passes an observer, two cars passing
simultaneously would not produce 140 dBrather, they would combine to produce
73 dB, a difference of 3 dB. Under the decibel scale, three sources of equal loudness
together produce a sound level 5 dB louder than one source.
3.5. A -Weighted Decibels
The decibel scale alone does not adequately characterize how humans perceive noise.
The dominant frequencies of a sound have a substantial effect on the human response
to that sound. Although the intensity (energy per unit of area) of the sound is a purely
physical quantity, the loudness or human response is determined by the characteristics
of the human ear.
Human hearing is limited in the range of audible frequencies as well as in the way it
perceives the SPL in that range. In general, people are most sensitive to the frequency
range of 1,000-8,000 Hz and perceive sounds in that range better than sounds of the
same amplitude in higher or lower frequencies. To approximate the response of the
human ear, sound levels of individual frequency bands are weighted, depending on
the human sensitivity to those frequencies. An "A -weighted" sound level (expressed
in units of A -weighted decibels [dBA]) can then be computed based on this
information.
The A -weighting network approximates the frequency response of the average young
ear when listening to most ordinary sounds. When people make judgments regarding
the relative loudness or annoyance of a sound, their judgments correlate well with the
A -scale sound levels of those sounds. Other weighting networks have been devised to
address high noise levels or other special problems (e.g., B, C, and D scales), but
these scales are rarely used in conjunction with highway traffic noise. Noise levels for

3.6. Human Response to Changes in Noise Levels
As discussed previously, doubling sound energy results in a 3 dB increase in sound.
However, given a sound level change measured with precise instrumentation, the
subjective human perception of a doubling of loudness will usually be different than
what is measured.
Under controlled conditions in an acoustical laboratory, the trained, healthy human
ear is able to discern 1 dB changes in sound levels when exposed to steady, single -
frequency ("pure -tone") signals in the midfrequency range (1,000-8,000 Hz).
In typical noisy environments, 1-2 dB changes in noise are generally not perceptible.
However, it is widely accepted that people are able to begin to detect sound level
increases of 3 dB in typical noisy environments. Further, a 5 dB increase is generally
perceived as a distinctly noticeable increase, and a 10 dB increase is generally
perceived as a doubling of loudness. Therefore, a doubling of sound energy
Fairview Street Improvements from 9th Street to 16th Street 13
and Bridge Replacement Project Noise Study Report
3. Fundamentals of Traffic Noise
(e.g., doubling the volume of traffic on a highway) that would result in a 3 dB
increase in sound would generally be perceived as barely detectable.
3.7. Noise Descriptors
Noise in the daily environment fluctuates over time. Some fluctuations are minor, but
some are substantial. Some noise levels occur in regular patterns, but others are
random. Some noise levels fluctuate rapidly, but others fluctuate slowly. Some noise
levels vary widely, but others are relatively constant. Various noise descriptors have
been developed to describe time -varying noise levels. The following are the noise
descriptors most commonly used in traffic noise analysis:
• Equivalent Continuous Sound Level (Leq): Leq represents an average of the
sound energy occurring over a specified period of time. In effect, Leq is the
steady-state sound level containing the same acoustical energy as the time -varying
sound that actually occurs during the same period. The 1-hour A -weighted
equivalent continuous sound level (Leq[h]) is the energy average of A -weighted
sound levels occurring during a 1-hour period and is the basis for the NAC used
by Caltrans and the FHWA.
• Percentile -Exceeded Sound Level (Lxx): Lxx represents the sound level exceeded
for a given percentage of a specified period of time (e.g., Llo is the sound level
exceeded 10 percent of the time and L90 is the sound level exceeded 90 percent of
the time).
• Maximum Instantaneous Sound Level (Lmax): Lma., is the highest instantaneous
sound level measured during a specified period.
• Day -Night Level (Ld„): Ld„ is the energy average of A -weighted sound levels
occurring over a 24-hour period, with a 10 dB penalty applied to A -weighted
sound levels occurring during the nighttime hours between 10:00 p.m. and
7:00 a.m.
• Community Noise Equivalent Level (CNEL): Similar to L&, CNEL is the
energy average of the A -weighted sound levels occurring over a 24-hour period,
with a 10 dB penalty applied to A -weighted sound levels occurring during the
nighttime hours between 10:00 p.m. and 7:00 a.m., and a 5 dB penalty applied to
the A -weighted sound levels occurring during the evening hours between
7:00 p.m. and 10:00 p.m.

and Bridge Replacement Project Noise Study Report
Chapter 3. Fundamentals of Traffic Noise
3.8. Sound Propagation
When sound propagates over a distance, it changes in level and frequency content.
The manner in which noise reduces with distance depends on the factors described
below.
3.8.1. Geometric Spreading
Sound from a localized source (i.e., a 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.
3.8.2. Ground Absorption
The propagation path of noise from a highway to a receptor is usually very close to
the ground. Noise attenuation from ground absorption and reflective wave canceling
adds to the attenuation associated with geometric spreading. Traditionally, the excess
attenuation has also been expressed in terms of attenuation per doubling of distance.
This approximation is usually sufficiently accurate for distances of less than 200 ft.
For acoustically hard sites (i.e., sites with a reflective surface between the source and
the receptor [e.g., a parking lot or body of water]), no excess ground attenuation is
assumed. For acoustically absorptive or soft sites (i.e., sites with an absorptive ground
surface between the source and the receptor [e.g., 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.
3.8.3. Atmospheric Effects
Receptors located downwind from a source can be exposed to increased noise levels
relative to calm conditions, whereas locations upwind can have lowered noise levels.
Sound levels can be increased at large distances (e.g., more than 500 ft) from the
highway due to atmospheric temperature inversion (i.e., increasing temperature with
elevation). Other factors (e.g., air temperature, humidity, and turbulence) can also
have significant effects.

and Bridge Replacement Project Noise Study Report
3. Fundamentals of Traffic Noise
3.8.4. Shielding by Natural or Human -Made Features
A large object or barrier in the path between a noise source and a receptor can
substantially attenuate noise levels at the receptor. The amount of attenuation
provided by shielding depends on the size of the object and the frequency content of
the noise source. Natural terrain features (e.g., hills and dense woods) and human -
made features (e.g., buildings and walls) can substantially reduce noise levels.
Walls are often constructed between a source and a receptor specifically to reduce
noise. A barrier that breaks the line of sight between a source and a receptor will
typically result in at least 5 dB of noise reduction. Taller barriers provide increased
noise reduction. Vegetation between a highway and a receptor is rarely effective in
reducing noise because it does not create a solid barrier.

Chapter 4. Federal, State, and Local
Policies and Procedures
This report focuses on the requirements of 23 CFR 772, as discussed in this chapter.
4.1. Federal Regulations
4.1.1. 23 CFR 772
23 CFR 772 provides procedures for preparing operational and construction noise
studies and evaluating noise abatement considered for federal and federal -aid
highway projects. Under 23 CFR 772.7, projects are categorized as Type 1, Type 2,
or Type 3 projects.
The FHWA defines a Type 1 project as a proposed federal or federal -aid highway
project for the construction of a highway on a new location or the physical alteration
of an existing highway that significantly changes either the horizontal or vertical
alignment of the highway. The following projects are also considered Type 1
projects:
• The addition of a through -traffic lane or lanes. This includes the addition of a
through -traffic lane that functions as a high -occupancy vehicle lane,
high -occupancy toll lane, bus lane, or truck climbing lane.
• The addition of an auxiliary lane, except for when the auxiliary lane is a turn lane.
• The addition or relocation of interchange lanes or ramps added to a quadrant to
complete an existing partial interchange.
• Restriping existing pavement for the purpose of adding a through -traffic lane or
an auxiliary lane.
• The addition of a new or substantial alteration of an existing weigh station, rest
stop, ride -share lot, or toll plaza.
If a project is determined to be a Type 1 project under this definition, the entire
project area as defined in the environmental document is a Type 1 project. A Type 2
project is a noise barrier retrofit project that involves no changes to highway capacity
or alignment. A Type 3 project is a project that does not meet the classifications of a
Type 1 or Type 2 project. Type 3 projects do not require a noise analysis.
Under 23 CFR 772.11, noise abatement must be considered for Type 1 projects if the
project is predicted to result in a traffic noise impact. In such cases, 23 CFR 772
Fairview Street Improvements from 9th Street to 16th Street 17
and Bridge Replacement Project Noise Study Report
ter 4. Federal, State, and Local Policies and Procedures
requires that the project sponsor "consider" noise abatement before adoption of the
final NEPA document. This process involves identification of noise abatement
measures that are reasonable, feasible, and likely to be incorporated into the project,
and of noise impacts for which no apparent solution is available.
Traffic noise impacts, as defined in 23 CFR 772.5, occur when the predicted noise
level in the design year approaches or exceeds the NAC specified in 23 CFR 772,
or a predicted noise level substantially exceeds the existing noise level (i.e., a
"substantial" noise increase). The terms "substantial increase" or "approach" are not
specifically defined in 23 CFR 772; these criteria are defined in the Protocol, as
described in the following section.
Table 4.1 summarizes the NAC corresponding to various land use activity categories.
Activity categories and related traffic noise impacts are determined based on the
actual land use in a given area.

4.1.2. Traffic Noise Analysis Protocol for New Highway Construction
and Reconstruction Projects
The Caltrans Protocol specifies the policies, procedures, and practices to be used by
agencies that sponsor new construction or reconstruction of federal or federal -aid
highway projects. The NAC specified in the Protocol are the same as those specified
in 23 CFR 772. The Protocol defines a noise increase as "substantial" when the
predicted noise levels under build conditions exceed existing noise levels by 12 dBA.
The Protocol also states that a sound level is considered to approach an NAC level
when the sound level is within 1 dB of the NAC identified in 23 CFR 772
(e.g., 66 dBA is considered to approach the NAC of 67 dBA, but 65 dBA is not).
The Caltrans TeNS (September 2013) and the Protocol provide detailed technical
guidance for the evaluation of highway traffic noise. This includes field measurement
methods, noise modeling methods, and report preparation guidance.
4.2. State Regulations and Policies
4.2.1. California Environmental Quality Act
Noise analysis under CEQA may be required regardless of whether the proposed
Project is a Type 1 project. The CEQA noise analysis is completely independent of
the 23 CFR 772 analysis done for NEPA. Under CEQA, the baseline noise level is
compared to the build noise level. The assessment entails looking at the existing
setting and how large or perceptible any noise increase would be in a given area. Key
considerations include the uniqueness of the setting, the sensitive nature of the noise
receptors, the magnitude of the noise increase, the number of residences affected, and
the absolute noise level.
The significance of noise impacts under CEQA are addressed in the environmental
document rather than in the NSR. Even though the NSR (or noise technical
memorandum) does not specifically evaluate the significance of noise impacts under
CEQA, it must contain the technical information that is needed to make that
determination in the environmental document.
4.2.2. Section 216 of the California Streets and Highways Code
Section 216 of the California Streets and Highways Code relates to the noise effects
of a proposed freeway project on public and private elementary and secondary
schools. Under this code, a noise impact occurs if, as a result of a proposed freeway
project, noise levels exceed 52 dBA Leq(h) in the interior of public or private
elementary or secondary school classrooms, libraries, multipurpose rooms, or spaces.
Fairview Street Improvements from 9th Street to 16th Street 19
and Bridge Replacement Project Noise Study Report
ter 4. Federal, State, and Local Policies and Procedures
This requirement does not replace the "approach or exceed" NAC criterion for
FHWA Activity Category D for classroom interiors, but it is a requirement that must
be addressed in addition to the requirements of 23 CFR 772.
If a project results in a noise impact under this code, noise abatement must be
provided to reduce classroom noise to a level that is at or below 52 dBA Leq(h). If the
noise levels generated from freeway and nonfreeway sources exceed 52 dBA Leq(h)
prior to construction of the proposed freeway project, noise abatement must be
provided to reduce noise to the level that existed prior to project construction.
4.3. Local Regulations and Policies
4.3.1. City of Santa Ana
Section 18-314 of the City's Municipal Code prohibits the construction, repair,
remodeling, or grading of any real property except between the hours of 7:00 a.m.
and 8:00 p.m. on weekdays and Saturdays. No such work is permitted on Sundays
and federal holidays.

Chapter 5. Study Methods and
Procedures
5.1. Methods for Identifying Land Uses and Selecting Noise
Measurement and Modeling Receptor Locations
A field investigation was conducted to identify land uses that could be subject to
traffic and construction noise impacts from the proposed Project. Land uses in the
project area were categorized by land use type, activity category (as defined in
Table 4.1), and frequency of human use. An area of frequent human use is an area
where people are exposed to traffic noise for an extended period of time on a regular
basis. One practical test for determining frequent human use is the presence of
existing facilities that invite human use such as benches, barbeque facilities, covered
group picnic areas, and uncovered picnic tables. As stated in the Protocol, noise
abatement is only considered for areas of frequent human use that would benefit from
a lowered noise level. Accordingly, this noise impact analysis focuses on locations
with defined outdoor activity areas (e.g., residential backyards, parks, and sitting
areas).
The topographical features of the project area relative to nearby existing and planned
land uses, such as hills and changes in terrain, were also identified.
Fifteen short-term measurement locations were selected to represent noise -sensitive
land uses in the project area. Two long-term measurement sites were selected to
capture the diurnal traffic noise level pattern in the project area. Short-term
measurement locations were selected to serve as representative modeling locations.
Also, other nonmeasurement locations were selected as modeling locations. A total of
92 receptor locations were modeled to represent land uses in the project area. These
monitoring and modeled receptor locations are shown on Figure 5-1.
5.2. Field Measurement Procedures
A field noise study was conducted in accordance with the recommended procedures
in the Caltrans TeNS (2013). The following is a summary of the procedures used to
collect short-term and long-term sound level data.

Chapter 5. Study Methods and Procedures
5.2.1. Short -Term Measurements
Short-term noise level measurements in the project vicinity were sampled during
off-peak traffic hours when traffic was flowing freely. Short-term noise level
measurements were made using Larson Davis Model 831, 824, and 820 Type 1 sound
level meters.
The following measurement procedures were used:
• Calibrate the sound level meter.
• Set up the sound level meter at a height of 5 ft.
• Commence noise monitoring.
• Collect site -specific data (e.g., date, time, direction of traffic, vehicle speed, and
location of the sound level meter relative to any existing feature).
• Count passing vehicles for a period of 20 minutes during noise level
measurement. Vehicles are split into three categories: automobiles, medium
trucks, and heavy trucks.
• Stop measurement after 20 minutes.
• Calibrate the sound level meter.
• Proceed to the next monitoring site and repeat.
The traffic counts were expanded to hourly volumes (multiplied by three to normalize
the results to hourly values) and entered into the FHWA Traffic Noise Model (TNM)
2.5 (2004) for each monitoring site. The monitoring results were used to calibrate the
model outputs.
5.2.2. Long -Term Measurements
Two long-term noise level measurements were conducted using one dosimeter in the
study area. The purpose of the long-term measurements was to identify variations in
sound levels throughout the day.
5.3. Traffic Noise Level Prediction Methods
Traffic noise levels were predicted using the FHWA's TNM 2.5 (FHWA 2004). TNM
2.5 is a computer model based on two FHWA reports: FHWA-PD-96-009 and
FHWA PD-96-010 (FHWA 1998a, 1998b). Key inputs to TNM 2.5 were the
locations of roadways, traffic mix, vehicle speeds, shielding features (e.g., topography
and buildings), noise barriers, ground type, and receptors.

and Bridge Replacement Project Noise Study Report
5. Study Methods and Procedures
The existing and future 2040 traffic (design year) noise levels at all 92 receptor
locations were modeled using either the worst -case traffic operations (prior to speed
degradation) or peak -hour traffic volumes, whichever were lower. The worst -case
traffic condition is assumed to be level of service C and is generally loudest when
vehicles on a given roadway travel at free -flowing traffic conditions. Accordingly, the
worst -case traffic volume assumptions are based on the maximum number of vehicles
that can typically travel in a given lane while still resulting in free -flowing traffic
conditions. The worst -case traffic condition is assumed to be 750 vehicles per lane
per hour (vplph) on Fairview Street and other local roadways. The a.m. peak -hour
traffic volume was selected over the p.m. peak -hour traffic volume because the worst -
hour noise levels based on the long-term (24-hour) noise level measurements occur
during the a.m. hour. The a.m. and p.m. peak -hour traffic volumes were obtained
from the Traffic Impact Analysis (LSA 2018). A summary of traffic data inputs for
existing and future conditions is provided in Appendix A.
TNM 2.5 is sensitive to the volume of trucks on the roadway because trucks
contribute disproportionally to traffic noise. Vehicle distributions on Fairview Street
were obtained from traffic counts collected during ambient noise level measurement.
Vehicle distribution on other local roadways in the project area was assumed to be
similar to Fairview Street. Table 5.1 shows the vehicle distribution and vehicle speeds
for each vehicle category in the project area used to calculate existing and future
traffic noise levels.

5.4. Methods for Identifying Traffic Noise Impacts and
Consideration of Abatement
Traffic noise impacts are considered to occur at receptor locations where predicted
design -year noise levels are at least 12 dBA greater than existing noise levels, or
where predicted design -year noise levels approach or exceed the NAC for the
applicable activity category. Where traffic noise impacts are identified, noise
28 Fairview Street Improvements from 9th Street to 16th Street
and Bridge Replacement Project Noise Study Report
Chapter 5. Study Methods and Procedures
abatement must be considered for reasonableness and feasibility as required by
23 CFR 772 and the Protocol.
According to the Protocol, an abatement measure is considered acoustically feasible if
a minimum noise reduction of 5 dBA at impacted receptor locations is predicted with
implementation of the abatement measure. In addition, barriers should be designed to
intercept the line of sight from the exhaust stack of a truck to the first tier of receptors
as required by the Caltrans Highway Design Manual (2015), Chapter 1100. Other
factors that affect feasibility include topography, access requirements for driveways
and ramps, presence of local cross -streets, utility conflicts, other noise sources in the
area, and safety considerations. The overall reasonableness of noise abatement is
determined by considering factors such as the construction cost of the barrier, the
noise reduction design goal (a noise level reduction of 7 dBA or more at one or more
benefited receptors), and the viewpoints of benefited receptors (including property
owners and residents of the benefited receptors).
The Protocol defines the procedure for assessing the reasonableness of noise barriers
from a cost perspective. A cost allowance per residence is assigned to each benefited
residence (i.e., residences that receive at least 5 dBA of noise reduction from a noise
barrier). The 2018 allowance is $95,000 per benefited residence. Total allowances are
calculated by multiplying the cost allowance per residence by the number of benefited
residences.

6.2. Noise Measurement Results
The existing noise environment in the project area is based on short-term (20-minute)
and long-term (24-hour) noise level measurements.
6.2.1. Short -Term Monitoring
The primary source of noise in the project area is vehicular traffic on Fairview Street.
Short-term (20-minute) noise measurements were conducted to document existing
noise levels at 15 representative receptor locations in the project area. Short-term
noise level measurements were conducted using Larson Davis Models 831, 824, and
820 Type 1 sound level meters. Table 6.1 contains the results of the short-term noise
level measurements along with a description of the physical location of each
monitoring site. These short-term noise measurements were used to calibrate the
noise model and to predict the noise levels at all 92 modeled receptors in the project
area. The short-term monitoring locations are shown on Figure 5-1. The concurrent
traffic counts and observed vehicle speeds are provided in Appendix A. The noise
monitoring results for each monitoring site are included in Appendix C.

6.2.2. Long -Term Monitoring
Long-term traffic noise level measurements were conducted to document the peak
traffic noise hour. Long-term ambient noise monitoring was conducted using one
dosimeter at two representative locations in the project area. The long-term noise
level measurement at LT-1 was performed from 9:00 a.m. on Tuesday, April 17,
2018, to 9:00 a.m. on Wednesday, April 18, 2018, at a single-family residence at
1008 North King Street. Table 6.3 shows that traffic noise peaks during the 6:00 a.m.,
7:00 a.m., and 8:00 a.m. hours at LT-1. The long-term noise level measurement at
LT-2 was performed from 2:00 p.m. on Wednesday, April 18, 2018, to 2:00 p.m. on
Thursday, April 19, 2018, at a single-family residence at 2505 West 16th Street.
Table 6.4 shows that traffic noise peaks during the 8:00 a.m. hour at LT-2. The long-
term noise monitoring locations are shown on Figure 5-1. The long-term noise level
measurement results are shown in Tables 6.3 and 6.4.
6.3. Noise Model Calibration
Eight separate model runs for the 15 monitoring locations were conducted using the
traffic counts and observed vehicle speeds collected during the ambient noise
monitoring. The results of these model runs were compared to the measured ambient
noise levels to ensure the accuracy of TNM 2.5. Correction factors known as
K-factors were applied to each of the modeled receptor locations so that the
monitored and modeled noise levels were the same. Table 6.5 shows the measured
ambient noise level, the modeled noise levels using traffic counts and measured
vehicle speeds during noise monitoring, and the K-factor at each of the 15 monitored
locations.
As shown in Table 6.5, some of the monitoring locations have K-factors greater than
3 dBA but less than 5 dBA. Based on Section 4.4.1.6 of the TeNS, K-factors between
3 and 4 can be calibrated unless the validity of the noise measurement conducted is in
serious doubt.

field surveys of existing features and the TNM 2.5 modeled input data were
re-examined and determined to be accurate. Therefore, the K-factors shown in
Table 6.5 were used to calibrate the noise model.
6.4. Existing Noise Levels
The existing a.m. peak -hour traffic volumes obtained from the Traffic Impact Analysis
(LSA 2018) or the worst -case traffic operations (prior to speed degradation),
whichever were lower, were coded into TNM 2.5 with existing roadway conditions.
The a.m. peak -hour traffic volumes were selected over the p.m. peak -hour traffic
volumes because the long-term (24-hour) noise level measurements indicate that the
peak noise hour occurs during this period. Table B.1 in Appendix B provides the
results of the existing traffic noise modeling. Figure 5-1 shows the locations of the
modeled receptors.

7.1. Future Noise Environment and Impacts
This NSR was prepared to determine the future traffic noise impacts at receptors
along Fairview Street. Potential long-term noise impacts under the Future Build
condition are solely from traffic noise. Traffic noise was evaluated for the worst -case
traffic condition. Using coordinates obtained from the topographic maps, 92 receptor
locations were evaluated in the model.
Future traffic noise levels at all 92 receptor locations were determined using either the
worst -case traffic operations (prior to speed degradation) or the 2040 a.m. peak -hour
traffic volumes obtained from the Traffic Impact Analysis (LSA 2018), whichever
were lower, as described in Section 5.3. Table B.1 in Appendix B summarizes the
TNM results for the Existing, Future No Build, and Future Build conditions. The
modeled future noise levels with the proposed Project were compared to the modeled
existing noise levels (after calibration) from TNM 2.5 to determine whether a
substantial noise increase would occur. The modeled future noise levels were also
compared to the NAC to determine whether a traffic noise impact would occur.
Traffic noise impacts occur when either of the following occurs: (1) the traffic noise
level at a receptor location is predicted to "approach or exceed" its corresponding
NAC or (2) the predicted traffic noise level is 12 dBA or more over the corresponding
modeled existing noise level at the receptor locations analyzed. When traffic noise
impacts occur, noise abatement measures must be considered. Of the 92 modeled
receptors, 9 receptors under the Future Build condition would approach or exceed the
NAC. No receptor would experience a substantial noise increase of 12 dBA or more
over its corresponding modeled existing noise level under any scenario. The receptor
locations listed below would be or would continue to be exposed to noise levels that
either approach or exceed the NAC under Future Build conditions.
• Receptor R-5: This receptor location represents an existing single-family
residence on the northbound side of Fairview Street between Civic Center Drive
and West 9th Street. Currently, a 4.7 ft high existing wall shields the residence.

and Bridge Replacement Project Noise Study Report
ter 7. Future Noise Environment, Impacts, and Considered Abatement
One noise barrier (Noise Barrier [NB] No. 1) was modeled along the private
property line on the northbound side of Fairview Street to shield this residence.
• Receptor R-8: This receptor location represents an existing single-family
residence on the southbound side of Fairview Street between Civic Center Drive
and West 9th Street. Currently, a 2.7 ft to 6 ft high existing wall shields this
residence. One noise barrier (NB No. 2) was modeled along the private property
line on the southbound side of Fairview Street to shield this residence.
• Receptor R-14: This receptor location represents an existing single-family
residence on the southbound side of Fairview Street between West 9th Street and
West 12th Street. Currently, a 5.3 ft high existing wall shields this residence. One
noise barrier (NB No. 3) was modeled along the private property line on the
southbound side of Fairview Street to shield this residence.
• Receptor R-23: This receptor location represents existing multifamily residences
on the southbound side of Fairview Street between West 9th Street and West 12th
Street. Existing wood fences along the private property line would not provide
effective noise attenuation at these residences. One noise barrier (NB No. 4) was
modeled along the private property line on the southbound side of Fairview Street
to shield these residences.
• Receptors R-24, R-25, and R-40: These receptor locations represent existing
single-family residences on the northbound side of Fairview Street between
West 9th Street and West 12th Street. Currently, a 4 ft to 6 ft high wall shields
these residences. One noise barrier (NB No. 5) was modeled along the private
property line on the northbound side of Fairview Street to shield these residences.
• Receptor R-46: This receptor location represents an existing single-family
residence on the southbound side of Fairview Street between West 12th Street and
the Santa Ana River. Currently, a 5.7 ft high existing wall shields this residence.
One noise barrier (NB No. 6) was modeled along the private property line on the
southbound side of Fairview Street to shield this residence.
• Receptor R-51: This receptor location represents a park on the southbound side
of Fairview Street between West 12th Street and the Santa Ana River. Currently,
no wall shields the park. Because there is driveway and pedestrian access onto
Fairview Street, it is not feasible to abate traffic noise from Fairview Street with
noise barriers.
7.2. Preliminary Noise Abatement Analysis
Noise abatement is considered where noise impacts are predicted in areas of frequent
human use that would benefit from a lowered noise level. According to 23 CFR
40 Fairview Street Improvements from 9th Street to 16th Street
and Bridge Replacement Project Noise Study Report
Chapter 7. Future Noise Environment, Impacts, and Considered Abatement
772(13)(c) and 772(15)(c), federal funding may be used for the following abatement
measures:
• Construction of noise barriers, including acquisition of property rights, either
within or outside the highway right-of-way.
• Traffic management measures including, but not limited to, traffic control devices
and signing for prohibition of certain vehicle types, time -use restrictions for
certain vehicle types, modified speed limits, and exclusive lane designations.
• Alteration of horizontal and vertical alignments.
• Acquisition of real property or interests therein (predominantly unimproved
property) to serve as a buffer zone to preempt development that would be
adversely impacted by traffic noise.
Noise barriers are the only form of noise abatement considered for this project. Each
noise barrier has been evaluated for feasibility based on achievable noise reduction.
For each noise barrier found to be acoustically feasible, reasonable cost allowances
were calculated by multiplying the number of benefited receptors by $95,000.
Table B.1 in Appendix B summarizes the results at receptor locations for the noise
barriers evaluated in detail for this project. Table B.1 shows predicted noise levels,
insertion loss, and the number of benefited receptors at analyzed barrier heights for
the Future Build condition.
For any noise barrier to be considered reasonable from a cost perspective, the
estimated cost of the noise barrier should be equal to or less than the total cost
allowance calculated for the barrier. The cost calculations of the noise barrier must
include all items appropriate and necessary for its construction (e.g., traffic control,
drainage modification, retaining walls, landscaping for graffiti abatement, and right-
of-way costs). Construction cost estimates are not provided in this NSR but will be
presented in the Noise Abatement Decision Report (NADR). The NADR is a design
responsibility and is prepared to compile information from the NSR, other relevant
environmental studies, and design considerations into a single comprehensive
document before public review of the project. The NADR is prepared by the project
engineer after completion of the NSR and prior to publication of the draft
environmental document. The NADR includes noise abatement construction cost
estimates that have been prepared and signed by the project engineer based on
site -specific conditions. Construction cost estimates are compared to reasonableness
allowances in the NADR to identify which wall configurations are reasonable from a
cost perspective.

ter 7. Future Noise Environment, Impacts, and Considered Abatement
The design of noise barriers presented in this report is preliminary and has been
conducted at a level appropriate for environmental review and not for final design of
the project. Preliminary information on the physical location, length, and height of
noise barriers is provided in this report. If pertinent parameters change substantially
during the final project design, preliminary noise barrier designs may be modified or
eliminated from the final project. A final decision on the construction of the noise
abatement will be made upon completion of the project design.
7.2.1. Future Build
The following is a discussion of the noise abatement measures considered for the
Future Build condition where traffic noise impacts are predicted.
7.2.1.1. Noise Barrier No. 1
A 169 ft long barrier (STA 36+55 to STA 37+31) along the private property line on
the northbound side of Fairview Street between Civic Center Drive and 9th Street was
analyzed to shield Receptor R-5. Table B.1 in Appendix B shows the results of the
analysis. NB No. 1 was evaluated from 6 ft to 16 ft high in 2 ft increments. Figure 7-1
shows the location of NB No. 1. Table 7.1 lists the highest noise barrier reduction, the
number of benefited residences, the reasonable allowance per benefited residence,
and the total reasonable allowance for each barrier height. The minimum feasible
barrier height is 8 ft.

and Bridge Replacement Project Noise Study Report
Chapter 8. Construction Noise
Two types of short-term noise impacts would occur during construction of the
proposed Project. The first type would be from construction crew commutes and the
transport of construction equipment and materials to the project site that would
incrementally raise noise levels on access roads leading to the site. The pieces of
heavy equipment for grading and construction activities will be moved on site, will
remain for the duration of each construction phase, and will not add to the daily
traffic volumes in the project vicinity. A high single -event noise exposure potential at
a maximum level of 84 dBA Lm,,x from trucks passing at 50 ft will exist. However, the
projected construction traffic volume will be minimal when compared to existing
traffic volumes on Fairview Street and other adjacent roadways, and the associated
long-term noise level change will not be perceptible. Therefore, short-term
construction -related worker commutes and equipment transport noise impacts would
be less than substantial.
The second type of short-term noise impact is related to noise generated during
roadway construction. Construction is performed in discrete steps, each of which has
its own mix of equipment and, consequently, its own noise characteristics. These
various sequential phases would change the character of the noise generated and the
noise levels in the project area as construction progresses. Despite the variety in the
type and size of construction equipment, similarities in the dominant noise sources
and patterns of operation allow construction -related noise ranges to be categorized by
work phase. Table 8.1 lists typical construction equipment noise levels (Lmax)
recommended for noise impact assessments based on a distance of 50 ft between the
equipment and a noise receptor.
Typical noise levels at 50 ft from an active construction area range up to 88 dBA L n x
during the noisiest construction phases. The site preparation phase, which includes
grading and paving, tends to generate the highest noise levels because the noisiest
construction equipment is earthmoving equipment. Earthmoving equipment includes
excavating machinery (e.g., backfillers, bulldozers, and front loaders). Earthmoving
and compacting equipment includes compactors, scrapers, and graders. Typical
operating cycles for these types of construction equipment may involve 1 or
2 minutes of full -power operation followed by 3 or 4 minutes at lower power settings.

Note: Noise levels reported in this table are rounded to the nearest whole number.
Maximum noise levels were developed based on Spec 721.560 from the CA/T program to be consistent with
the City of Boston's Noise Code for the "Big Dig" project.
2 The maximum noise level was developed based on the average noise level measured for each piece of
equipment during the CANT program in Boston, Massachusetts.
3 Because the maximum noise level based on the average noise level measured for this piece of equipment was

Construction of the proposed Project is expected to require the use of graders,
bulldozers, and water trucks/pickup trucks. Noise associated with the use of
construction equipment is estimated to be between 55 and 85 dBA Lmax at a distance
of 50 ft from the active construction area for the grading phase. As seen in Table 8.1,
the maximum noise level generated by each grader is assumed to be approximately
85 dBA Lmax at 50 ft from the grader in operation. Each bulldozer would generate
approximately 85 dBA Lmax at 50 ft. The maximum noise level generated by water
trucks/pickup trucks is estimated to be approximately 55 dBA Lmax at 50 ft from these
vehicles. Each doubling of the sound source with equal strength increases the noise
level by 3 dBA. Each piece of construction equipment operates as an individual point
source. The worst -case composite noise level at the nearest residence during this
52 Fairview Street Improvements from 9th Street to 16th Street
and Bridge Replacement Project Noise Study Report
Chapter 8. Construction Noise
phase of construction would be 88 dBA L,..,, at a distance of 50 ft from an active
construction area. Based on a usage factor of 40 percent, the worst -case combined
noise level during this phase of construction would be 84 dBA Leq at a distance of
50 ft from the active construction area.
The closest residences are located approximately 50 ft from the project construction
areas. Therefore, the closest residences may be subject to short-term noise reaching
88 dBA L.,,, generated by construction activities in the project area. Compliance with
Section 14-8.02 of the Caltrans Standard Specifications and Section 18-314 of the
City's Municipal Code will be required to minimize construction noise impacts on
land uses adjacent to the project site. In compliance with these regulations, the
contractor shall not perform any construction activities between the hours of
8:00 p.m. and 7:00 a.m. on weekdays and Saturdays, or at any time on Sundays and
federal holidays.

I.L.: Insertion Loss.
2 Activity categories without outdoor frequent human use areas were not evaluated against the NAC.
3 No barrier was analyzed at this location because the modeled receptor would not approach or exceed the NAC.
° Numbers in bold represent noise levels that approach or exceed the NAC.
5 Underlined noise levels have been attenuated by at least 5 dBA (i.e., feasible barrier height).
6 NF = Not Feasible.
A/E = Approach/Exceed Leq(h) = 1-hour A -weighted equivalent continuous sound level
dB = decibel(s) NAC = Noise Abatement Criteria
dBA = A -weighted decibel(s) NB = Noise Barrier
EW = Existing Wall NBR = Number of Benefited Receptors
ft = foot/feet PL = property line
ROW = right-of-way
