Summary
The purpose of this Noise Study Report (NSR) is to evaluate noise impacts and
abatement under the requirements of the 2011 Alaska Department of Transportation and
Public Facilities (DOT&PF) Noise Policy (2011 Noise Policy). The 2011 Noise Policy
provides procedures for preparing operational and construction noise studies and
evaluating noise abatement considered for federal and federal-aid highway projects.
The proposed Abbott Road Rehabilitation Project proposes to rehabilitate two miles of
Abbott Road between Lake Otis Parkway and Birch Road. Proposed improvements
include widening the road to accommodate a two-way left-turn lane, an additional
Eastbound thru lane at Lake Otis Parkway, lengthened crest vertical curves, rehabilitation
of the existing pathway from Lake Otis Parkway to Trailside Elementary driveway, and a
right turn lane from eastbound Abbott Road onto Birch Road.
The proposed project is considered a Type I project according to 23 CFR 772 because it
would add an auxiliary travel lane to Abbott Road. A noise analysis is required for all
Type I projects. A Type I project is defined in 23 CFR 772 as follows:
“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, which substantially changes either the horizontal or vertical
alignment, increases the number of through-traffic lanes, or adds an
auxiliary lane.”
Terrain in the project area is generally rolling with roadway grades ranging from flat to a
maximum of approximately 6.4 percent. Existing land uses in the project area include
residential, open space/recreational, commercial, institutional, industrial, medical, and
undeveloped land uses. However, the land uses affected by the proposed project include
single-family residential, open space/recreational (Ruth Arcand Park), institutional
(schools), medical uses, and a hotel. The primary source of noise in the project area is
traffic from Abbott Road. Traffic noise level predictions were made with the Federal
Highway Administration (FHWA) Traffic Noise Model (TNM®) Version 2.5 (FHWA,
2004). Using traffic volumes, speeds, roadway alignments, and cross-sections for the
project, the predicted future plus project noise levels were compared to existing ambient
noise levels and to applicable noise abatement criteria (NAC) to assess the project’s
potential noise impacts. This noise analysis evaluates noise exposure in terms of the
hourly equivalent sound level (Leq) during noisiest traffic hour and compares predicted
traffic noise levels to federal and state NAC and to existing noise levels to assess impacts.
The peak-traffic-noise-hour Leq describes the noise level that is equivalent to the energy

Summary
average noise levels that would be measured continuously during the hour producing the
highest traffic noise during a typical 24-hour period.
Five noise level measurements were conducted at representative locations to document
the existing ambient noise environment and calibrate the noise prediction model with
concurrent traffic counts and measured vehicle speeds. Noise measurements were taken
in areas representative of sensitive land uses closest to Abbott Road. The existing noise
levels measured were between 62.5 and 66.1 A-weighted decibels (dBA) in the project
area. A total of 87 noise sensitive receptors that represent the residential areas, Ruth
Arcand Park, institutional uses (schools), medical facilities, a hotel, and undeveloped land
along the project corridor were modeled and evaluated for potential noise impacts
resulting from traffic noise.
Existing, Future No Build, and Future Plus Project (Build) noise levels were computed
for the 87 noise-sensitive receptors. The predicted project Build noise levels were
compared to existing noise levels and to the applicable NAC to assess potential projectrelated noise impacts. None of the 87 modeled receptors in the project area exceed the
applicable NAC under Future Plus Project conditions. Therefore, the project would not
create a noise impact at any sensitive receptors in the project area, and consideration of
noise abatement measurements was not required.
During construction of the project, noise from construction activities may intermittently
dominate the noise environment in the immediate area of construction. No adverse noise
impacts from construction are anticipated because construction would be conducted in
accordance with the 2011 Noise Policy, federal regulation 23 CFR 772, and the
Anchorage Municipal Charter.

1.1.
Purpose of the Noise Study Report
The purpose of this Noise Study Report (NSR) is to evaluate noise impacts and
abatement under the requirements of Title 23, Part 772 of the Code of Federal
Regulations (23 CFR 772) “Procedures for Abatement of Highway Traffic Noise”. 23
CFR 772 provides procedures for preparing operational and construction noise 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.
The Alaska Department of Transportation and Public Facilities (DOT&PF) Noise Policy,
dated April 2011 (2011 Noise Policy), provides DOT&PF policy for implementing 23
CFR 772 in Alaska. The 2011 Noise Policy outlines the requirements for preparing noise
study reports.

Chapter 3. Fundamentals of Traffic Noise
The following is a brief discussion of fundamental traffic noise concepts. For a detailed
discussion, please refer to DOT&PF’s 2011 Noise Policy, which is available on
DOT&PF’s Web site at:
http://www.dot.alaska.gov/stwddes/desenviron/assets/pdf/resources/aknoisepolicy.pdf.
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, such as
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
receiver, and the propagation path between the two. The loudness of the noise source and
obstructions or atmospheric factors affecting the propagation path to the receiver
determines the sound level and characteristics of the noise perceived by the receiver. The
field of acoustics deals primarily with the propagation and control of sound.
3.2.
Frequency
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 micro-Pascals (mPa). One mPa is
approximately one hundred billionth (0.00000000001) of normal atmospheric pressure.
Sound pressure amplitudes for different kinds of noise environments can range from less
than 100 to 100,000,000 mPa. Because of this huge range of values, sound is rarely
expressed in terms of mPa. Instead, a logarithmic scale is used to describe sound
pressure level (SPL) in terms of decibels (dB). The threshold of hearing for young
people is about 0 dB, which corresponds to 20 mPa.

Chapter 3 Fundamentals of Traffic Noise
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 sound 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 dB—rather, they would combine to produce 73 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 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 within 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. Then, an “A-weighted” sound level (expressed in
units of dBA) can 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 of 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 traffic noise
reports are typically reported in terms of A-weighted decibels or dBA. Table 3-1, Typical
A-Weighted Noise Levels, describes typical A-weighted noise levels for various noise
sources.

Human Response to Changes in Noise Levels
As discussed above, 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 (1,000 Hz–8,000 Hz) range. In typical noisy
environments, changes in noise of 1 to 2 dB 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 (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 our 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 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 Sound Level (Leq): Leq represents an average of the sound energy
occurring over a specified period. 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 sound level (Leq[h]) is
the energy average of A-weighted sound levels occurring during a one-hour period,
and is the basis for noise abatement criteria (NAC) used by DOT&PF and FHWA.

Percentile-Exceeded Sound Level (Lxx): Lxx represents the sound level exceeded
for a given percentage of a specified period (e.g., L10 is the sound level exceeded 10
percent of the time, and L90 is the sound level exceeded 90 percent of the time).

Maximum Sound Level (Lmax): Lmax is the highest instantaneous sound level
measured during a specified period.

Day-Night Level (Ldn): Ldn 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 nighttime hours between 10 p.m. and 7 a.m.

Community Noise Equivalent Level (CNEL): Similar to Ldn, CNEL is the energy
average of the A-weighted sound levels occurring over a 24-hour period, with a 10dB penalty applied to A-weighted sound levels occurring during the nighttime hours
between 10 p.m. and 7 a.m., and a 5-dB penalty applied to the A-weighted sound
levels occurring during evening hours between 7 p.m. and 10 p.m.
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 following factors.
Abbott Road Rehabilitation Project Project from Lake Otis Parkway to Birch Road Noise Study Report
July 2015
8
Chapter 3 Fundamentals of Traffic Noise
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 decibels 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 decibels for each doubling of distance from a line source.
3.8.2. 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 sufficiently accurate for distances of less than 200 feet. 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 decibels 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 decibels 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 feet) from the
highway 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.
3.8.4. Shielding by Natural or Human-Made Features
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. 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

Chapter 3 Fundamentals of Traffic Noise
constructed between a source and a receiver specifically to reduce noise. A barrier that
breaks the line of sight between a source and a receiver will typically result in at least 5
dB of noise reduction. Taller barriers provide increased noise reduction. Vegetation
between the highway and receiver is rarely effective in reducing noise because it does not
create a solid barrier.

Chapter 4. Federal Regulations and State
Policies
This report focuses on the requirements of 23 CFR 772 and the 2011 DOT&PF Noise
Policy, as discussed below.
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, projects are categorized as Type I, Type II, or Type III projects.
FHWA defines a Type I 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 which substantially changes either the horizontal or vertical alignment, or
increases the number of through-traffic lanes. A Type II project is a noise barrier retrofit
project that involves no changes to highway capacity or alignment. DOT&PF does not
participate in Type II projects. Type III federal projects are those that neither meet the
definitions of Type I or Type II and for which a noise analysis is not required and no
consideration of noise abatement is warranted.
Type I projects include those that create a completely new noise source, as well as those
that increase the volume or speed of traffic or move the traffic closer to a receiver. Type
I projects include the addition of an interchange, ramp, auxiliary lane, or truck-climbing
lane to an existing highway, or widening an existing ramp by a full lane width for its
entire length. Projects unrelated to increased noise levels, such as striping, lighting,
signing, and landscaping projects, are not considered Type I projects.
Under 23 CFR 772, noise abatement must be considered for Type I projects if the project
is predicted to result in a traffic noise impact. 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 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 (a “substantial” noise increase). 23 CFR 772 does not
specifically define the terms “substantial increase” or “approach;” these criteria are
defined in the 2011 Noise Policy, as described below.

In identifying noise impacts, primary consideration is given to exterior areas of frequent
human use. In situations where there are no exterior activities, or where the exterior
activities are far from the roadway or physically shielded in a manner that prevents an
impact on exterior activities, the interior criterion (Activity Category D) is used as the
basis for determining a noise impact.
4.2.
State Regulations and Policies
4.2.1.
Alaska Department of Transportation and Public Facilities Noise
Policy
The 2011 Noise Policy describes DOT&PF’s implementation of the requirements of the
FHWA Noise Standard at 23 CFR 772. The 2011 Noise Policy defines a noise increase
as substantial when the predicted future worst case noise level with project
Abbott Road Rehabilitation Project Project from Lake Otis Parkway to Birch Road Noise Study Report
July 2015

Chapter 4 Federal Regulations and State Policies
implementation is greater than or equal to an increase of 15 dBA over the existing noise
level. The 2011 Noise Policy also states that a sound level is considered to approach a
NAC level when the sound level is within 1 dBA 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 2011 Noise Policy provides detailed technical guidance for the evaluation of
highway traffic noise. This includes field measurement methods, noise modeling

Chapter 5. Study Methods and Procedures
5.1.
Methods for Identifying Land Uses and Selecting Noise
Measurement and Modeling Receiver 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 the
extent of frequent human use. Although all developed land uses are evaluated in this
analysis, the focus is on locations of exterior frequent human use that would benefit from
a lowered noise level. Accordingly, this impact analysis focuses on locations with
defined outdoor activity areas, such as residential backyards and common use areas at
multi-family residences.
Five noise measurement locations were selected to represent noise sensitive areas in close
proximity to Abbott Road, and also serve as noise modeling locations. Four noise
measurement locations represent residential uses, and one measurement location
represents a medical use [Anchorage Community Mental Health Services Inc.
(Daybreak)]. It is noted that all five noise measurement locations are considered areas of
“frequent human use” and are representative of the ambient noise levels at the sensitive
areas closest to Abbott Road. In general, 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. In addition to the noise measurement locations, several other non-measurement
locations were selected as modeling locations.
5.2.
Field Measurement Procedures
A field noise study was conducted to determine the existing noise environment in the
project vicinity. The following is a summary of the procedures used to collect sound
level data.
5.2.1. Existing Sound Level Measurements
Sound level data was collected at five locations on Wednesday, May 20, 2015, and
Thursday, May 21, 2015, using a Brüel & Kjær Hand-held Analyzer Type 2250 equipped
with a Type 4189 pre-polarized microphone. The monitoring equipment complies with
applicable requirements of the American National Standards Institute (ANSI) for Type I
(precision) sound level meters. Two measurements were taken, each for a 15-minute
period at each site (as required by the 2011 Noise Policy). As noted above, four
measurements were conducted at residential land uses (Activity Category B), and one
Abbott Road Rehabilitation Project Project from Lake Otis Parkway to Birch Road Noise Study Report
July 2015

Chapter 5 Study Methods and Procedures
measurement was conducted at a medical land use (Activity Category C). Noise levels
ranged between 62.5 and 66.1 dBA Leq. The measurement locations are identified in
Exhibit 5a through 5c, Noise Monitoring and Modeling Locations.
During the measurements, field staff attended the sound level meter. Leq values collected
during the measurement period (15 minutes in duration) were logged, and dominant noise
sources observed were also identified and logged. Using this approach, times when
traffic noise was observed to be a dominant contributor to noise levels could be
distinguished from non-traffic noise sources (such as aircraft and lawn equipment) that
may have contributed significantly to existing noise levels.
Temperature, wind speed, and humidity were recorded manually during the monitoring
session. During the measurements, wind speeds typically ranged from 0 to 5 miles per
hour (mph), and temperatures ranged from 59-66° degrees Fahrenheit.
Traffic on Abbott was classified and counted during the noise measurements. Vehicles
were classified as automobiles, medium-duty trucks, or heavy-duty trucks. An
automobile was defined as a vehicle with two axles and four tires that are designed
primarily to carry passengers. Small vans and light trucks were included in this category.
Medium-duty trucks included all cargo vehicles with two axles and six tires. Heavy-duty
trucks included all vehicles with three or more axles. The posted speed on Abbott Road
is 45 mph.
5.3.
Traffic Noise Levels Prediction Methods
Traffic noise levels were predicted using the FHWA Traffic Noise Model Version 2.5
(TNM 2.5). TNM 2.5 is a computer model based on two FHWA reports: FHWA-PD-96009 and FHWA-PD-96-010 (FHWA 1998a, 1998b). Key inputs to the traffic noise
model were the locations of roadways, shielding features (e.g., topography and
buildings), noise barriers, ground type, and receivers. Three-dimensional representations
of these inputs were developed using CAD drawings, aerials, and topographic contours
provided.

Exhibit 5c
Chapter 5 Study Methods and Procedures
Traffic noise was evaluated under existing conditions, design year no-project conditions,
and design year conditions with the project alternative. Abbott Road traffic volumes
based on a Level of Service (LOS) C traffic volume of 450 vehicles/lane/hour,1 vehicle
classification percentages, and traffic speeds under Existing, Future No Build, and Future
Plus Project conditions were input into the traffic noise model.
Traffic noise was also modeled for the following cross-streets (and associated speed
limits) along Abbott Road: Lake Otis Parkway (45 mph), Elmore Road (45 mph north of
Abbott Road, 25 mph south of Abbott Road), Carlson Road (25 mph), Spring Hill Drive
(25 mph), and Birch Road (45 mph). LOS C traffic volumes (450 vehicles/lane/hour)
were input for the aforementioned cross-streets, and were modeled for Existing, Future
No Build, and Future Plus Project conditions. Tables A-1 and A-2 in Appendix A
summarize the traffic volumes and assumptions used for modeling existing and designyear conditions with and without the project alternative.
To validate the accuracy of the model, TNM 2.5 was used to compare the measured
traffic noise levels to modeled noise levels at the field measurement locations (refer to
Table 6-1) and were normalized to 1-hour volumes. These normalized volumes were
assigned to the corresponding project area roadways to simulate the traffic noise during
the actual measurement period. Modeled and measured sound levels were then compared
to determine the accuracy of the model and if additional calibration of the model was
necessary.
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 approach or exceed the NAC for the applicable activity category, or
where predicted design-year noise levels are at least 15 dBA greater than existing noise
levels. Where traffic noise impacts are identified, noise abatement must be considered
for reasonableness and feasibility as required by the 2011 Noise Policy.
According to the 2011 Noise Policy, abatement measures are considered acoustically
feasible if a minimum noise reduction of 5 dBA or more is achieved for at least 50
percent of the first row dwelling units, and the abatement measure is considered nonhazardous (i.e., in compliance with the general design principles in the 2011 Noise
Policy). 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 three factors: (1) viewpoints of the property owners and
residents of the benefitted receptors; (2) cost effectiveness; and (3) ability to meet noise
reduction design goal.
The 2011 Noise Policy defines the procedure for assessing reasonableness of noise
barriers from a cost perspective. A cost-per-residence allowance is calculated for each
benefited residence (i.e., residences that receive at least 5 dBA of noise reduction from a
noise barrier). The base allowance for a benefitted receptor is $32,000. In addition, a
noise barrier is determined to be reasonable when the noise abatement measure results in
a minimum 7 dBA noise reduction at 50 percent or more of first row dwelling units.
Lastly, the viewpoints of property owners and residents must be solicited to determine if
noise abatement is desired (i.e., At least 60 percent of households and property owners
surveyed must want the noise abatement measure).

Chapter 6. Existing Noise Environment
6.1.
Existing Land Uses
A field investigation was conducted to identify land uses that could be subject to traffic
and construction noise impacts from the proposed project. Single-family residences
(Activity Category B), Anchorage Community Mental Health Services Inc. (Daybreak,
Activity Category C), AK Child & Family (Activity Category C), Trailside Elementary
School (Activity Category C), Robert Service High School (Activity Category C), Pacific
Northern Academy (Activity Category C), Abbott Loop Community Church (Activity
Category C and D), Grace and Truth Community Church (Activity Category C and D),
Ruth Arcand Park (Activity Category C), Country Road Manor Bed and Breakfast
(Activity Category E), and undeveloped land (Activity Category G) were the identified
land uses in the project area.
As required by the 2011 Noise Policy, although all developed land uses are evaluated in
this analysis, noise abatement is only considered for areas of frequent human use that
would benefit from a lowered noise level. Accordingly, this impact analysis focuses on
locations with defined outdoor activity areas, such as residential backyards, parks, and
common use areas.
6.2.
Noise Measurement Results
The existing noise environment in the project area is characterized below based on the
noise monitoring that was conducted.
6.2.1.
Existing Sound Level Measurements
The existing noise environment in the project area is described below based on noise
monitoring that was conducted at five representative noise-sensitive receptor locations.
The primary source of noise in the project area is traffic along Abbott Road. Table 6-1
summarizes the results of the noise monitoring conducted in the project area. The noise
measurement locations are also depicted in Exhibit 5a through 5c.
TNM 2.5 was used to compare measured traffic noise levels to modeled noise levels at
the field measurement locations (refer to Exhibit 5a through 5c). Table 6-2, Comparison
of Measured to Predicted Sound Levels in the TNM Model, compares measured and
modeled noise levels at the noise measurement locations M-1 through M-5. The
predicted sound levels are within 3 dB of the measured sound levels
Abbott Road Rehabilitation Project Project from Lake Otis Parkway to Birch Road Noise Study Report

and are, therefore, considered to be in reasonable agreement with the measured sound
level. Therefore, no calibration of the model was made.

Notes:
1. Modeling results are rounded to the nearest decibel.
2. The measured noise levels and modeled noise levels are not directly comparable, as the measured
levels consist of ambient noise recorded over a 15-minute time period, while the modeled traffic
noise levels were calculated using DOT&PF LOS C traffic volumes of 450 vehicles/lane/hour on
Abbott Road, and the following cross-streets: Lake Otis Parkway, Elmore Road, Carlson Road,
Spring Hill Drive, and Birch Road.
3. A 20 dBA noise attenuation rate was utilized to determine the interior noise levels for standard
construction per the U.S. Department of Housing and Urban Development, The Noise Guidebook,
March 2009, page 14.

Notes:
1. Modeling results are rounded to the nearest decibel.
2. Future No Build traffic noise volumes are equal to existing volumes, assuming 450 vehicles/lane/hour (i.e., under Future No Build conditions, the
Abbott Road alignment/capacity would remain unchanged compared to existing conditions, thus, resulting in the same traffic volumes and noise
levels).
3. The measured noise levels and modeled noise levels are not directly comparable, as the measured levels consist of ambient noise recorded over
a 15-minute time period, while the modeled traffic noise levels were calculated using DOT&PF LOS C traffic volumes of 450 vehicles/lane/hour
for Abbott Road and the following cross-streets: Lake Otis Parkway, Elmore Road, Carlson Road, Spring Hill Drive, and Birch Road.
4. A 20 dBA noise attenuation rate was utilized to determine the interior noise levels for standard construction per the U.S. Department of Housing
and Urban Development, The Noise Guidebook, March 2009, page 14.

Chapter 7 Future Noise Environment, Impacts, and Considered Abatement
Modeling results in Table 7-1 indicate that predicted traffic noise levels for the designyear with-project conditions do not exceed the applicable NAC at any modeled receptors.
In addition, no noise-sensitive receptors within the project area would be exposed to a
project-related increase in noise levels of 15 dB or more. Therefore, the project would
not result in traffic noise impacts at any receptors in the vicinity of the project site, and
consideration of noise abatement measures is not required.

Chapter 8. Construction Noise
During construction of the project, noise from construction activities may intermittently
dominate the noise environment in the immediate area of construction. Construction
noise is regulated by federal regulation 23 CFR 772 - Procedures for Abatement of
Highway Traffic Noise and Construction Noise, and the 2011 Noise Policy. Table 8-1,
Construction Equipment Noise, summarizes noise levels produced by construction
equipment that is commonly used on roadway construction projects. Construction
equipment is expected to generate noise levels up to 95 dB at a distance of 25 feet, 89 dB
at 50 feet, and 83 at 100 feet. Noise produced by construction equipment would be
reduced over distance at a rate of about 6 dB per doubling of distance.

The closest sensitive receptors are located approximately 25 feet to the east of the project
construction area. Therefore, these receptor locations could be subject to noise between
approximately 86 and 95 dBA Lmax generated by construction activities along Abbott
Road. However, no adverse noise impacts from construction are anticipated because
construction would be conducted in accordance with the 2011 Noise Policy, federal
regulation 23 CFR 772, and applicable local noise standards. Construction noise would
be short-term, intermittent, and overshadowed by local traffic noise.
Further,
implementing the following measures would minimize the temporary noise impacts from
construction:

All equipment will have sound-control devices that are no less effective than those
provided on the original equipment. No equipment will have an unmuffled exhaust.

The contractor will implement appropriate additional noise mitigation measures,
including changing the location of stationary construction equipment, turning off
Abbott Road Rehabilitation Project Project from Lake Otis Parkway to Birch Road Noise Study Report

Chapter 8 Construction Noise
idling equipment, rescheduling construction activity, notifying adjacent residents in
advance of construction work, and installing acoustic barriers around stationary
construction noise sources.
Compliance with the construction hours specified in the Anchorage Municipal Charter
(i.e., construction is prohibited between the hours of 10:00 p.m. and 6:00 a.m. during the
construction season,2 or between the hours of 10:00 p.m. and 7:00 a.m. during other
months, or at any time on Sundays or state holidays) would be complied with in order to
minimize construction noise. The Anchorage Municipal Charter also prohibits
construction activities such that the sound level therefrom exceeds an Leq of 80 dB(A) at
or within a residential, commercial, or industrial real property boundary, or within a
noise-sensitive zone during any one hour of the daily period from 6:00 a.m. to 10:00 p.m.
during the construction season, or from 7:00 a.m. to 10:00 p.m. during other months.
Further, the Contractor shall equip all internal combustion engines with the manufacturerrecommended muffler and shall not operate any internal combustion engine on the job
site without the appropriate muffler.
Construction season means the period from April 1 through October 31, both dates inclusive, of each
year.

Notes:
1.
Based on Level of Service C volumes (450 vehicles per lane, per hour).
2.
The project is a roadway rehabilitation project, and the proposed improvements would not add capacity to Abbott Road. The project would add turn lanes and lengthen crest vertical
curves. Therefore, the Abbott Road roadway widths were extended in the TNM2.5 model to accommodate the proposed turning lanes and other improvements.
3.
The speed limit along Elmore Road is 25 miles per hour south of Abbott Road.

Notes:
1. Modeling results are rounded to the nearest decibel.
2. Future No Build traffic noise volumes are equal to existing volumes, assuming 450 vehicles/lane/hour (i.e., under Future No Build conditions, the Abbott Road alignment/capacity
would remain unchanged compared to existing conditions, thus, resulting in the same traffic volumes and noise levels).
3. The measured noise levels and modeled noise levels are not directly comparable, as the measured levels consist of ambient noise recorded over a 15-minute time period, while
the modeled traffic noise levels were calculated using DOT&PF LOS C traffic volumes of 450 vehicles/lane/hour.
4. 4. A 20 dBA noise attenuation rate was utilized to determine the interior noise levels for standard construction per the U.S. Department of Housing and Urban Development, The
Noise Guidebook, March 2009, page 14.

Appendix D DOT&PF 2011 Noise Policy
This appendix includes the April 2011 Alaska Department of Transportation & Public
Facilities (DOT&PF) Noise Policy.
Abbott Road Rehabilitation Project Project from Lake Otis Parkway to Birch Road Noise Study Report
July 2015

Alaska Department of Transportation & Public Facilities Alaska Environmental Procedures Manual Noise Policy April 2011 INTRODUCTION
This document contains the Alaska Department of Transportation and Public Facilities
(DOT&PF) noise policy on highway traffic noise and construction noise. This policy
describes DOT&PF's implementation of the requirements of the Federal Highway
Administration (FHWA) Noise Standard at 23 Code of Federal Regulations (CFR) Part
772 (see Appendix A). This policy also addresses how traffic noise is considered on
state funded projects. It applies to both design-build and design-bid-build projects.
DOT&PF developed this policy and submitted it to FHWA for their review and
concurrence.
Noise is defined as unwanted sound. Sound is produced by the vibration of sound
pressure waves in the air. Sound pressure levels are used to measure the intensity of
sound and are described in terms of decibels. The decibel (dB) is a logarithmic unit
which expresses the ratio of the sound pressure level being measured to a standard
reference level. Sound is composed of various frequencies, but the human ear does not
respond to all frequencies. Frequencies to which the human ear does not respond must
be filtered out when measuring highway noise levels. Since noise is measured on a
logarithmic scale, an increase 10 dB in the sound pressure level will be perceived by an
observer to be a doubling of the sound whereas a decrease in 10 dB will be perceived
as a halving of the sound. For example, a sound at 70 dB will be perceived as twice as
loud as a sound at 60 dB.
The level of highway traffic noise depends on three things: (l) the volume of the traffic,
(2) the speed of the traffic, and (3) the number of trucks in the flow of the traffic.
Generally, the loudness of traffic noise is increased by heavier traffic volumes, higher
speeds, and greater numbers of trucks. Vehicle noise is a combination of the noises
produced by the engine, exhaust, and tires. The loudness of traffic noise can also be
increased by defective mufflers or other faulty equipment on vehicles. Any condition
(such as a steep incline) that causes heavy laboring of motor vehicle engines will also
increase traffic noise levels. In addition, there are other more complicated factors that
affect the loudness of traffic noise. For example, as a person moves away from a
highway, traffic noise levels are reduced by distance, terrain, vegetation, and natural
and manmade obstacles. While traffic noise is not usually a problem for people who
live more than about 450 feet (150 meters) from heavily traveled freeways or more than
about 90-180 feet (30 to 60 meters from lightly traveled roads) there may be incidences
(ex. quiet settings, rural areas, etc.) where people can detect highway noise over
greater distances.
During the rapid expansion of the Interstate Highway System and other roadways in the
20th century, communities began to recognize that highway traffic noise and
construction noise had become important environmental impacts. In the 1972 Federalaid Highway Act, Congress required FHWA to develop a noise standard for new federalaid highway projects. While providing national criteria and requirements for all highway
agencies, the FHWA Noise Standard gives highway agencies flexibility that reflects
state-specific attitudes and objectives in approaching the problem of highway traffic and
Alaska EPM Noise Policy 2 April 2011 construction noise. This policy contains DOT&PF's policy on how highway traffic and
construction noise impacts are defined, how noise abatement is evaluated, and how
noise abatement decisions are made.
In addition to defining traffic noise impacts, the FHWA Noise Standard requires that
noise abatement measures be considered when traffic noise impacts are identified for
Type I federal projects, as defined in 23 CFR 772.5. For a more detailed definition of a
Type I project see the definitions section of this policy. Noise abatement measures that
are found to be feasible and reasonable must be constructed for Type I federal projects.
Feasible and reasonable noise abatement measures are eligible for federal-aid
participation at the same ratio or percentage as other eligible project costs. The
DOT&PF has accepted the federal definition of a Type I project for all state-funded
projects as well.
Federal regulations also include standards for Type II federal projects. A Type II federal
project is defined as a federal or federal-aid highway project for noise abatement on an
existing highway. For a Type II project to be eligible for federal-aid funding, the state
highway agency must develop and implement a Type II program in accordance with 23
CFR 772.7(e). Type II programs are entirely voluntary. The DOT&PF has elected not
to participate in a Type II program to retrofit existing state highways with noise
abatement.
Type III federal projects are those that neither meet the definitions of Type I or Type II
and for which a noise analysis is not required and no consideration of noise abatement
is warranted. The DOT&PF has accepted the federal definition of a Type III projects for
all state-funded projects as well.
PURPOSE
This policy describes the DOT&PF program to implement 23 CFR 772. Where FHWA
has given DOT&PF flexibility in implementing the standard, this policy describes the
DOT&PF approach to implementation. This policy also defines how the DOT&PF
addresses traffic noise in the design and construction of state-funded projects.
NOISE STANDARDS
This policy outlines the DOT&PF program to implement the FHWA Noise Standards
found in 23 CFR 772. It also describes how the DOT&PF addresses traffic noise on
state-funded projects. These standards include traffic noise prediction requirements,
noise analyses, noise abatement criteria, and requirements for informing local officials.
The State of Alaska does not have any traffic noise regulations. It is the DOT&PF policy
to follow the federal standards for traffic noise prediction requirements, and noise
analyses. Federal noise abatement criteria are followed to determine whether noise
Alaska EPM Noise Policy 3 April 2011 impacts exist and if abatement is feasible and reasonable, however, the decision to
provide noise abatement on state funded project follows slightly different procedures
(discussed the section of this policy entitled State-Funded Projects).
DEFINITIONS
The federal noise regulations definitions are located at 23 CFR 772.5. These
regulations are located in Appendix A.
Benefited Receptor. The recipient of an abatement measure that receives a noise
reduction at or above the minimum threshold of 5 dBA
Common Noise Environment. A group of receptors within the same Activity Category in
Table 1 that are exposed to similar noise sources and levels; traffic volumes, traffic mix,
and speed; and topographic features. Generally, common noise environments occur
between two secondary noise sources such as interchanges, intersections, and crossroads.
Date of Public Knowledge. The date of approval of the Categorical Exclusion (CE), the
Finding of No Significant Impact (FONSI) the Record of Decision (ROD), or in the case
of a state-funded project, approval of the State Environmental Checklist.
Design Year. The future year used to estimate the probable traffic volume for which a
highway is designed.
Existing Noise Levels: The worst noise hour, resulting from the combination of natural
and mechanical sources and human activity, usually present in a particular area. It
should be for the existing year of analysis.
Feasibility: The combination of acoustical and engineering factors considered in the
evaluation of a noise abatement measure.
Federal-aid Project: Any project utilizing federal funds for one or more phases (i.e.,
Environmental, Design, Right of Way, or Construction) or that is otherwise subject to
federal approval.
First Row Receivers: Closest residences or business impacted by noise from the
highway facility.
Impacted Receptor: The recipient that has a traffic noise impact.
L10: The sound level that is exceeded 10 percent of the time (the 90th percentile) for the
period under consideration, with L10(h) being the hourly value of L10.
Alaska EPM Noise Policy 4 April 2011 Leq: The equivalent steady-state sound level which in a stated period of time contains
the same acoustic energy as the time-varying sound level during the same time period,
with Leq(h) being the hourly value of Leq.
Multifamily Dwelling: A residential structure containing more than one residence. Each
residence in a multifamily dwelling shall be counted as one receptor when determining
impacted receptors and benefited receptors.
Noise Barrier: A physical obstruction constructed between the highway noise source
and the noise sensitive receptor(s) that lowers the noise level, including stand alone
noise walls, noise berms (earth or other material), and combination berm/wall systems.
Noise Reduction Design Goal: The optimum desired dBA noise reduction determined
from calculating the difference between future build noise levels with abatement, to
future build noise levels without abatement. The noise reduction design goal of the
DOT&PF is 7dBA.
Permitted: A definite commitment to develop land with an approved specific design of
land use activities as evidenced by the issuance of a building permit.
Property Owner: An individual or group of individuals that holds a title, deed, or other
legal documentation of ownership of a property or a residence.
Reasonableness: The combination of social, economic, and environmental factors
considered in the evaluation of a noise abatement measure.
Receptor: A discrete or representative location of a noise sensitive area(s), for any of
the land uses listed in Table 1.
Residence: A dwelling unit, either a single family residence or each dwelling unit in a
multifamily dwelling.
Resident: Someone who resides at a dwelling unit. May not necessarily be the owner of
the dwelling unit.
State-funded project: A project that is solely funded by state monies appropriated by
the Alaska State Legislature and requires no federal approvals for implementation.
Statement of Likelihood: A statement provided in the environmental clearance
document based on the feasibility and reasonableness analysis completed at the time
the environmental document is being approved.
Alaska EPM Noise Policy 5 April 2011 Substantial Construction: The granting of a building permit, prior to right-of-way
acquisition or construction approval, for the highway.
Substantial noise increase: One of two types of highway traffic noise impacts.
For a Type I project, DOT&PF considers an increase in noise levels of 15 dBA in the
design year over the existing noise level to be a substantial noise increase.
Traffic Noise Impacts: Design year build condition noise levels that approach or exceed
the NAC listed in Table 1 in 23 CFR 772 for the future build condition; or design year
build condition noise levels that create a substantial noise increase over existing noise
levels. The DOT&PF defines “approach” as 1 dBA below the FHWA noise abatement
criteria and a “substantial” noise increase as a 15 dBA increase over existing noise
levels.
Type I Project:
(1) The construction of a highway on new location; or,
(2) The physical alteration of an existing highway where there is either:
(i) Substantial Horizontal Alteration. A project that halves the distance between
the traffic noise source and the closest receptor between the existing condition to
the future build condition; or,
(ii) Substantial Vertical Alteration. A project that removes shielding therefore
exposing the line-of-sight between the receptor and the traffic noise source.
This is done by either altering the vertical alignment of the highway or by altering
the topography between the highway traffic noise source and the receptor; or,
(3) The addition of a through-traffic lane(s). This includes the addition of a through-traffic
lane that functions as a HOV lane, High-Occupancy Toll (HOT) lane, bus lane, or truck
climbing lane; or,
(4) The addition of an auxiliary lane, except when the auxiliary lane is a turn lane; or,
(5) The addition or relocation of interchange lanes or ramps added to a quadrant to
complete an existing partial interchange; or,
(6) Restriping existing pavement for the purpose of adding a through-traffic lane or an
auxiliary lane; or,
(7) The addition of a new or substantial alteration of a weigh station, rest stop, rideshare lot or toll plaza.
(8) If a project is determined to be a Type I project under this definition, the entire
project area as defined in the environmental document is a Type I project.
Type II Project: For a Type II project to be eligible for federal-aid funding, the highway
agency must develop and implement a Type II program in accordance with section
Alaska EPM Noise Policy 6 April 2011 772.7(e). The DOT&PF has elected not to participate in the voluntary Type II program at
this time1, so the retrofitting of noise barriers on existing roads is not currently done.
Type III Project: A federal or federal aid highway project that does not meet the
classifications of a Type I or Type II project. Type III projects do not require a noise
analysis or consideration of noise Abatement.
APPLICABILITY
This DOT&PF policy applies to all Type I federal highway projects in the State of
Alaska, that is, any projects that receive federal-aid funds or are otherwise subject to
FHWA approval. They include federal projects that are administered by Local Public
Agencies (LPAs) as well as DOT&PF.
This policy also applies to all Type I state-funded projects, and all Type I projects
proposed by Toll Road Authorities in the State of Alaska. Presently, the Knik Arm
Crossing Toll Authority (KABATA) is the only such authority in the State2. This policy
applies to state-funded design-build and design-bid-build projects. This policy does not
apply to Type III state-funded maintenance and operations activities and projects. In
general, the same methods are followed in the identification of noise impacts for statefunded projects as with federal-aid projects. For state-funded projects, results of noise
analyses will be documented in the State Projects Environmental Checklist. If noise
abatement is determined to be feasible and reasonable, the Regional Environmental
Manager will make a noise abatement recommendation to the Preconstruction
Engineer. The Preconstruction Engineer will decide whether the recommended
abatement measure will be constructed on state-funded projects. Abatement will be
provided only if it meets the feasibility and reasonableness criteria of this policy and the
state-funded appropriation can accommodate this expenditure.
The requirements of this policy apply uniformly and consistently to all Type I federal
projects, Type I state-funded projects, and Type I Toll Authority projects within the State
of Alaska.
DOT&PF has elected not to participate in the voluntary Type II noise program.
Consequently, the retrofitting of existing roads with noise abatement is not done by the
Department, unless there is a special appropriation by the State Legislature for such
abatement and the Department is designated the responsible agency for the project. In
those cases, the noise abatement measures being proposed must meet the feasibility
1
The Knik Arm Crossing Toll Authority (KABATA) has developed a PA that indicates that if Noise Abatement Criteria are exceeded then there will be noise barriers retrofitted to the project. 2
Projects that come out of KABATA are state‐funded, they follow the noise abatement procedures for State‐
funded projects, whereas if they are federally funded, they follow the procedures for federal projects. Alaska EPM Noise Policy 7 April 2011 and reasonableness criteria of this policy. Any disputes with this provision of the policy
and state lawmakers should be resolved by the DOT&PF Commissioner.
Type III projects are those projects that neither meet the definition of a Type I or Type II
project nor require a noise analysis or consideration of noise abatement.
If there are any questions about whether a project is subject to this policy or the FHWA
Noise Standard, contact the Regional Environmental Manager. Disagreements on these
determinations should be directed to the Statewide Environmental Manager. Due to the
long lead time necessary to complete a traffic noise study, the need for a noise study
should be determined early in project scoping.
TRAFFIC NOISE PREDICTION
The most recent version of the FHWA Traffic Noise Model (TNM), or other model
found acceptable to FHWA, pursuant to 23 CFR 772.9, will be utilized for all noise
predictions. The use of TNM Look-up Tables or any other model unacceptable to
FHWA is prohibited. Existing noise levels and future design year noise levels must be
predicted for all reasonable build alternatives carried forward in the National
Environmental Policy Act (NEPA) document. The future design year noise levels for
the No-Build alternative must also be predicted to satisfy documentation requirements
of NEPA.
The average pavement type must be used for all noise predictions unless the DOT&PF
obtains FHWA approval to use a different pavement type.
The use of noise contour lines can only be used for project alternative screening or for
land use planning purposes. Noise contour lines cannot be used for determining traffic
noise impacts. DOT&PF will use FHWA’s Traffic Noise Model most recently available
version to develop noise contours. The predictions will be for worst case hour noise
conditions. Generally, worst case hour are traffic levels at Level of Service (LOS) C or
D, rather than heavy traffic volumes. In heavily congested urban areas, the peak
traffic period (often LOS E or F) may not represent the worst noise conditions. For
example, speeds may be low and heavy truck volumes may drop as truckers try to
avoid severe congestion. Seasonal traffic variations should also be considered when
determining the worse case hour noise condition. The Project Manager should consult
with appropriate traffic and planning staff and review the annual traffic report in order
to determine the appropriate volumes and speeds to use in the analysis. This input
and any assumptions must be documented in the noise analyses report. DOT&PF will
use a design hourly volume (DHV) that correlate with Level C or D rather than peak
hour traffic. This will require coordination with Planning and Traffic to collect this
information.
Alaska EPM Noise Policy 8 April 2011 The input parameters for the TNM noise predictions should be documented in the
noise analysis report. Input parameters should be approved by the DOT&PF
Environmental Impact Analyst prior to modeling. All prediction results will be rounded
off to the closest whole number (i.e., 67.5 dBA will be rounded up to 68 dBA, 67.4 dBA
will be rounded down to 67dBA).
ANALYSIS OF TRAFFIC NOISE IMPACTS AND NOISE MEASUREMENTS
It is the DOT&PF Policy to utilize TNM noise predictions to model existing and future
worst case noise levels. Actual measurements of existing noise levels are only utilized
to validate TNM or other models acceptable to FHWA.
Noise Measurements
All noise measurements will be taken with an ANSI Type 1 or 2 integrating sound level
meter and will be A-weighted.
For proposed highways on new alignments where no highway currently exists, noise
measurements will be taken at representative receptor locations along the proposed
route in order to determine the existing noise level.
In general, noise measurements will be taken during either the morning or evening peak
traffic periods; or if LOS E or F exist, DOT&PF will use the traffic levels at Level of
Service (LOS) C or other time period to replicate the model. Noise measurements may
be taken outside the peak traffic periods for the sole intent of validating the TNM or
other model acceptable to FHWA. Noise measurements will follow FHWA procedures
for measuring traffic noise3. The locations, date, time, weather (sky cover, approximate
temperature, wind speed and direction, precipitation and snow cover), a description of
ground cover (hard or soft site), and traffic conditions (number of vehicles, percentage
medium and heavy trucks, motorcycles) will be recorded on each measurement data
sheet. Average traffic speeds can be estimated or measured and should also be noted
on the data sheet. A map depicting the measurement site relative to the road and
adjacent buildings must be provided (use actual measurements or locations using GPS,
estimated locations are not acceptable). Sufficient information should be provided to
allow re-creation of the measurements if necessary.
Two fifteen minute measurements will be taken at each receptor. Any noise sources
other than highway sources should be noted on the dated sheet.
Model Validation
3
FHWA Final Report – Measurement of Highway – Related Noise, 1996 [FHWA-PD-96-046DOT-VNTSCFHWA-96-5] Alaska EPM Noise Policy 9 April 2011 Noise measurements will be taken at representative locations throughout the proposed
project corridor. Locations of the measurements must be approved by the DOT&PF
Environmental Impact Analyst prior to being taken. Traffic counts will be taken
simultaneously with noise measurements. The actual traffic counts, vehicle types, and
speeds (estimated or measured) collected during the measurements will be utilized as
input to TNM for the purpose of validation. Noise prediction results will be compared
with actual measured results. Differences between the actual and predicted noise
measurements within ± 3dBA will be considered acceptable. If the difference is greater
than 3dBA, DOT&PF will coordinate with FHWA for direction. Either the model input will
be reevaluated at those locations to ensure an accurate representation of site geometry
and input, the noise measurements will be retaken, or shielding factors4 might be input
into TNM to offset these differences. Once the model is determined to be valid the
existing, Design Year Build (for all reasonable alternatives) and No-Build Noise Levels
can be predicted.
Noise Predictions and Impact Assessment
DOT&PF gives primary consideration to exterior areas of frequent human use. Noise
levels should typically be measured and/or predicted at exterior areas that receive
frequent human use at the first row of structures (i.e., residences and/or businesses).
These include patios or balconies of residential receivers. If access cannot be obtained
to take measurements on private property, then a location close to the highway right of
way line should be utilized. Measurements should not occur any closer than 10 feet
from a building or fence, because the object can reflect noise. The location of receptors
for noise predictions should be located at areas that receive frequent human use rather
than at the right of way line. Preferably, the receptor locations will be at locations that
will remain after construction of the proposed facility. Typically, a receptor location
should not be selected if the location will not exist after construction of the proposed
project because the basis for comparison would be lost. However, there may be some
receptors that are relocated with one Build Alternative and remain with another, so it is
not always possible to select receptor location that will exist after the construction of the
preferred alternative.
For Type I projects, a traffic noise analysis is required for all build alternatives under
detailed study in the NEPA process. All reasonable alternatives that have been carried
forward for detailed analysis within the categorical exclusion documentation,
environmental assessment or environmental impact statement and NOT rejected as
unreasonable during the alternatives screening process will be analyzed for noise
impacts. For Environmental Impact Statements or other studies that will examine broad
corridors, the appropriate scope and methodology of the noise analysis should be
4
Shielding factors are to be used only as an absolute last attempt option. In just about every case reviewing the location to ensure accuracy will either correct the differences. If not, then shielding factor is used as an adjustment factor that is applied to the single receiver to bring it into the 3 dB(A) range. Alaska EPM Noise Policy 10 April 2011 discussed with FHWA and other participating agencies early in the project planning
process.
For state-funded Type I projects a similar method of analysis will be followed. The
preferred alternative carried forward in the State Environmental Checklist will be
evaluated for noise impacts.
If any segment or component of an alternative meets the definition of a Type I project,
then the entire alternative is considered to be Type I and is subject to these noise
analysis requirements.
For Type I projects, the noise study area will be consistent with project limits, beginning
of the project to the end of the project based on logical termini for that specific project
(Beginning of Project to End of Project). The noise analysis must include analysis for
each Activity Category present in the study area.
LAND USE CATEGORIES
Federal land use activity categories are defined by 23 CFR 772. DOT&PF has
accepted the FHWA definition of these activity categories.
Activity Category A: Lands on which serenity and quiet are of extraordinary significance
and serve an important public need. DOT&PF must submit justifications to FHWA on a
case-by-case basis to designate any lands as Category A. Proposals and justifications
for designating land as Activity Category A will be submitted from the Regional
Environmental Manager through the state's FHWA Division Office and FHWA
Headquarters.
Activity Category B: Residential - exterior areas of single-family and multi-family homes.
Noise receptors should be located in areas that receive frequent human use (i.e.,
patios, balconies, playgrounds, gardens, etc.).
Activity Category C: Non-residential exterior areas of lands such as active sport areas,
amphitheaters, auditoriums, campgrounds, cemeteries, daycare centers, hospitals,
libraries, medical facilities, parks, picnic areas, places of worship, playgrounds, public
meeting rooms, public or nonprofit institutional structures, radio studios, recording
studios, recreation areas, Section 4(f) sites, schools, television studios, trails, and trail
crossings, etc. Receptors should be located in areas that represent the area that
receives the most frequent human use. Noise measurements and predictions will be
taken at an outdoor location that is representative of the typical use for this area that
receives the most frequent use. For structures, noise measurements and predictions
will be taken at a location that is representative of the exterior area that receives the
Alaska EPM Noise Policy 11 April 2011 most frequent use. Since the impact determinations are based on each area of frequent
human use, then the number of areas impacted would be calculated and an equivalent
number of residential units would be calculated to assess the feasibility and
reasonableness of any abatement measures. Equivalent number of residential units will
be calculated by determining the average residential lot size for the vicinity and then
dividing this into the non-residential area for a total amount of residential units. For
example: if a park has an area of 87,120 square feet, and the average residential lot
size is 60 feet by 200 feet or 12,000 square feet then we would use 8 equivalent
residential units to assess the feasibility and reasonableness of a proposed abatement
measure.
Activity Category D: Includes interiors of auditoriums, daycare centers, hospitals,
libraries, medical facilities, places of worship, public meeting rooms, public or nonprofit
institutional structures, radio studios, recording studios, schools, and television studios.
The impact determination will based on the area of frequent human use; therefore the
number of those areas that are impacted would be carried over to feasibility and
reasonableness. For example: If a daycare center has 15 various areas of frequent
human use (building and open space), but only 10 are impacted then 10 equivalent
residential units would be used for the feasibility and reasonableness determination. An
indoor analysis shall only be done after exhausting all reasonable outdoor analysis
options. If there are no exterior areas that receive frequent human use then
representative interior measurements may be appropriate if determined by
DOT&PF.Permission will be obtained from property owner to take interior noise
measurements at a designated receptor. Measurements will be taken with windows
closed and open if possible. Traffic counts will be taken concurrent with the
measurements.
Activity Category E: Exteriors of Hotels, motels, offices, restaurants/bars, and other
developed lands, properties or activities not included in A-D or F or other developed
lands that are less sensitive to highway noise. Noise measurements and predictions will
be taken at a location that is representative of the exterior area that receives the most
frequent use. The impact determination would be based on the total number of units
within the complex, and/or the capacity limit of the facility. For example: If a hotel has
45 units and two meeting areas with a total capacity of 100 people each, then the
number of receptors used for feasibility and reasonableness would be 200+ the 45
units.
Activity Category F: Agriculture, airports, bus yards, emergency services, industrial,
logging, maintenance facilities, manufacturing, mining, rail yards, retail facilities, shipyards, utilities (water resources, water treatment, electrical), warehousing, and other
land uses that are not sensitive to highway traffic noise. No highway noise analysis is
required under 23 CFR 772 at Activity Category F land uses. For example, no noise
analysis is required at locations that typically generate excessive levels of noise
themselves or where the activities taking place on them are not considered noise
Alaska EPM Noise Policy 12 April 2011 sensitive5 ) Proposals for designation of properties as Category F Activity Categories
must be approved by the Environmental Impact Analyst assigned to the project.
Activity Category G: (Undeveloped lands that are not permitted) Land permitted for
development (that is, a building permit has been issued on or before the date of public
knowledge), that land shall be analyzed under the Activity Category for that type of
development.
For land not permitted for development by the date of public knowledge (approval date
of NEPA document or State Environmental Checklist), DOT&PF shall determine future
noise levels pursuant to 23 CFR 772.17(a). The results shall be documented in the
project environmental documentation and in the noise analysis report. The analysis
should report the distance - measured from the proposed edge of the traveled way - to
the Noise Abatement Criteria (NAC) for all exterior land use categories. Any noise
abatement for such lands shall not be eligible for federal-aid participation.
DOT&PF DEFINITION OF “APPROACH THE NAC”
The DOT&PF defines “approach the NAC” as 1 dBA less than the NAC for Activity
Categories A-E in Table 1 that is located in Appendix B of this policy.
A traffic noise impact may occur even if the future noise level is lower than the existing
noise level. If the future noise level is 1 dBA less than or higher than the NAC for the
activity category, then a noise impact exists.
DOT&PF DEFINITION OF “SUBSTANTIAL INCREASE OVER EXISTING NOISE
LEVEL”
DOT&PF defines a “substantial increase over existing noise level” as 15 dBA over
existing noise levels. A substantial increase is independent of the absolute noise level.
A substantial increase over existing noise level is a noise impact, even if the future
noise level does not approach or exceed the NAC.
The traffic noise analysis will identify all measurement sites with the predecessor capital
letter M (i.e., M-1, M-2, M-3, etc.). All receptor sites where existing and future noise
levels are being predicted and where noise measurements were not taken will be
identified with the predecessor capital letter R (i.e., R-1, R-2, R-3, etc.). Receptors
where noise impacts are predicted to exist will be identified by receptor identification
number in the analyses report. Locations of the receptors will be identified on a map or

Predicted future Design Year No-Build Noise Level
Predicted future Design Year Build Noise Level for all reasonable alternatives
Identification of whether a noise impact exists or will exist at this receptor in the
future with and without the project.
ANALYSIS OF NOISE ABATEMENT MEASURES
A decision on whether to provide or not to provide a noise abatement measure must not
be arbitrary or capricious. The basis for the decision must be documented and
supportable, particularly if the decision is not to provide abatement and the affected
residents want an abatement measure to be constructed. The decision must be based
upon consistent and uniform application of this policy.
Noise abatement measures will be considered only when the existing or predicted future
traffic noise levels approach or exceed the FHWA Noise Abatement Criteria (Table 1),
or when the predicted future traffic noise levels (Design Year) of a build alternative
results in a substantial increase over the existing traffic noise levels. DOT&PF
considers a predicted noise level of 1 dBA below the FHWA Noise Abatement Criteria
as the condition of “approach”.
When traffic noise impacts are identified, then noise abatement shall be considered and
evaluated for acoustic feasibility and reasonableness. On a federal Type I project, then
the DOT&PF will construct it as a part of the project. For state Type I projects, if noise
abatement is considered feasible and reasonable, then the Regional Environmental
Manager will make a noise abatement recommendation to the Preconstruction
Engineer. The Preconstruction Engineer will decide whether the recommended
abatement measure will be constructed. Abatement will be provided on state funded
projects only if the Preconstruction Engineer determines that the state funded
appropriation can accommodate an expenditure on a noise abatement measure.
DOT&PF policy is that abatement for Activity Category A, B, C, D or E needs to be
feasible and reasonable on their own merits. DOT&PF does not provide noise
abatement measures for Activity Category F or G land uses unless it is necessary to
Alaska EPM Noise Policy 14 April 2011 protect adjacent sensitive land uses (for example if there is an Activity Category F or G
land use that is wedged into the project area that includes sensitive land uses, then by
default it will be evaluated for abatement). Land uses not sensitive to highway traffic
noise, and undeveloped lands will not be provided noise abatement.
Undeveloped land that is permitted for development (that is, a building permit has been
issued on or before the date of public knowledge) will be analyzed under the Activity
Category it has been permitted for. For example, if the undeveloped land is permitted to
be developed for residential land use (Activity Category B), then it will be considered
residential property in the analysis.
The following design principles from the “Guide on Evaluation and Abatement of Traffic
Noise, American Association of State Highway and Transportation Officials, 1993 and
“FHWA Highway Noise Barrier Design Handbook”, Federal Highway Administration,
December 2000 will be considered when determining whether to provide noise
abatement at impacted receptors.
Noise barriers will be designed such that they do not pose a hazard to birds or other
wildlife (i.e., clear panel barriers such as glass or plexiglass should not be used unless
there is some means incorporated into the panel to prevent bird collisions).
FEASIBILITY AND REASONABLENESS ANALYSIS
The two required criteria to consider when evaluating the incorporation of noise
abatement measures into a specific project are acoustic feasibility and reasonableness.
A noise abatement measure will be determined acoustically feasible and reasonable as
discussed below.
Acoustic Feasibility Criteria
Acoustic feasibility deals primarily with physics and engineering considerations (i.e., can
a substantial noise reduction be achieved given the conditions of a specific location; is
the ability to achieve noise reduction limited by factors such as topography, access
requirements for driveways or ramps, the presence of cross streets, or other noise
sources in the area).
1. Noise abatement measures are not feasible if a minimum of 5 dBA or more
reduction cannot be achieved for at least 50 percent of the front row dwelling
units. Noise abatement measures which do not achieve at least a 5 dBA
reduction are not prudent expenditures of public funds as any less of a reduction
is not easily detected by most people.
Alaska EPM Noise Policy 15 April 2011 2. Noise abatement measures are not feasible if they create a safety hazard to
the driving public, protected receptors or maintenance personnel. The Regional
Environmental Manager will consult with the Design and Maintenance &
Operations Sections when making this decision. The abatement measure should
be consistent with the following general design principles:





Noise abatement measures should be located beyond the recovery zone
of the traveled way; if a noise abatement measure is within 30 feet of the
traveled way, a traffic barrier may be warranted.
Noise abatement measures should not block the recommended site
distance (Alaska Highway Preconstruction Manual, Chapter 11) between
vehicles and intersecting roadways or on/off-ramps.
Protrusions on noise abatement measures near a traffic lane should be
avoided.
Facings on noise abatement measures that can become dislodged, or
barrier components that could shatter during an accident, or facings that
create excessive glare should be avoided.
Access should be provided to all sides of noise abatement measures to
allow for maintenance activities to take place.
All noise abatement measures should consider the design principles in the “Guide on
Evaluation and Abatement of Traffic Noise”, AASHTO, 1993.
a) Maintenance factors relating to replacement of materials damaged by impact,
cleaning the noise barrier, and maintenance associated with adjoining landscape
should be considered when determining feasibility.
b) Barrier access points for emergencies or water sources needed during
emergencies should be considered.
c) Minimum setback distances and placement of noise abatement measures
located at on/off-ramps and intersections should be based upon stopping sight
distances, which depend on driver reaction time and deceleration rate.
d) Placement of noise abatement measures should be a sufficient distance from
the travel way to assure adequate space for storage of plowed snow and to
assure that the abatement measure can withstand the additional loads that may
result from blown snow being both thrown and piled up against the noise
abatement measure.
e) Noise abatement measure design should minimize shading highways in critical
areas so that sunlight can melt ice or snow on the shoulders and travel lanes.
Reasonableness Criteria
Alaska EPM Noise Policy 16 April 2011 Reasonableness is a more subjective criterion than feasibility. It implies that common
sense and good judgment were applied in arriving at a decision. Reasonableness
should be based on a number of factors, not just one criterion. FHWA noise
regulations define three mandatory reasonableness factors that must be evaluated
for a noise abatement measure to be considered reasonable. They are:
A. Viewpoints of the property owners and residents of the benefitted
receptors
B. Cost Effectiveness
C. Noise Reduction Design Goal
The DOT&PF considers these three mandatory reasonableness factors to determine
reasonableness. The following optional reasonableness factors can only be used to
increase the cost allowed only on state-funded projects:
A. Date of development
B. Length of time receivers have been exposed to highway traffic noise
impacts
C. Exposure to higher absolute traffic noise Levels
D. Changes between existing and future build conditions
E. Percentage of mixed zone development
F. Use of noise compatible planning concepts by the local government
No single DOT&PF reasonableness factor shall be used to determine that a noise
abatement measure is unreasonable.
1. Cost Effectiveness (federal mandatory criterion). The noise abatement
measure cost is no more than $32,0006 per receptor, based upon the design
engineer’s estimate. This is determined by counting all receptors (including
owner-occupied, rental units, mobile homes, and businesses) benefited by the
noise abatement measure in any subdivision and/or given development, and
dividing that number into the total cost of the noise abatement measure. A
benefited receptor is defined as the recipient of an abatement measure that
receives a noise reduction at or above the minimum threshold of 5 dBA. Each
unit in a multi-family building will be counted as a separate receptor. Cost per
benefitted receptor must be reanalyzed at a regular interval not to exceed 5
years.
When the design engineer determines abatement measure cost, the estimate will
include all items necessary for the construction of the noise abatement measure.
Examples of cost items that should be included are traffic control, drainage
modification, foundations, retaining walls and right-of-way. Include a cost item
6
This figure was updated during DOT&PF 2009 development of a noise guideline to reflect inflation numbers of previous policies as well as updated with more current information that was provided by region offices. Alaska EPM Noise Policy 17 April 2011 only if it is directly related to the construction of the noise abatement measure7.
If a necessary a project feature, such as a retaining wall is included, then that
cost will not be added into the noise abatement construction cost estimate. If the
project incorporates visual mitigation such as the use of a transparent barrier with
surface texture, the additional cost will not be included in the abatement
construction cost estimate for the purpose of determining reasonableness.
Aesthetic treatments, such as artwork, re-vegetation, landscaping and barrier
treatments will not be included in the abatement measure cost estimate for the
purpose of determining reasonableness.
The cost per benefited receptor must be adjusted for inflation. Use the most
recent annual composite price index available from the FHWA Office of Program
Administration www.fhwa.dot.gov/programadmin/pricetrends.cfm. The latest price
index that FHWA developed is from 2006. This will be used until FHWA provides
more current index. In the event that FHWA does not provide a more current
index, DOT&PF will use the 2006 index and adjust it for inflation as necessary.
This will be accomplished by determining the ratio between the 2006 annual
composite index (221.3) and the most recent annual composite index available at
the time of the completion of the Noise Abatement Recommendation Worksheet
and adjust the $32,000 cost accordingly. DOT&PF will also take into
consideration the actual costs associated with project costs completed within the
time since 2006 in determining a more accurate cost per benefited receptor.
.
2. Views of the property owners and residents (federal mandatory criterion) that
benefit from noise abatement measures. To determine the desires of benefited
households and property owners, DOT&PF will contact all benefited households
and property owners to determine the level of interest for a noise abatement
measure. This contact could be in the form of a mail out questionnaire, phone
call survey, or door to door interviews whichever is most practical and cost
effective for the size of the proposed project. At least 60 percent of households
and property owners surveyed must want the noise abatement measure. The
term “household” is used instead of residents because a single dwelling unit
could have more or less inhabitants than another. The idea is not to give a
dwelling unit with multiple inhabitants more consideration than one with fewer
inhabitants. Also, property owners are also included as the dwelling units might
be rentals. The property owner should have a say in whether noise abatement is
provided to their property.
3. Noise reduction design goal (federal mandatory criterion). The DOT&PF noise
reduction design goal is 7dBA. 50 percent or more of the benefitted receptors in
the first row of structures must achieve this design goal for the noise abatement
7
DOT&PF will need to provide proof to the FHWA Division Office that the cost of any of these are solely and directly related to the noise abatement measure Alaska EPM Noise Policy 18 April 2011 to be considered reasonable. The DOT&PF goal is to provide more than the
minimum 7 dBA reduction to a majority of the benefitted receptors in the first row
of structures. This design goal is not extended to benefitted receptors beyond
the first row of structures, as the further one gets from the noise barrier the more
difficult it is to obtain a 7 dBA reduction.
The following criteria only apply to those state funded projects:
1. Development vs. Highway Timing (State funded only criterion). At least 50
percent of impacted receptors in the development (subdivision, apartment
complex, etc.) were built before initial construction of the highway. The date of
development is an important part of the determination of reasonableness. More
consideration is given to developments that were built before the highway was
built.
2. Development Existence (State funded only criterion). At least 50 percent of
impacted receptors in the development have existed for at least 10 years. More
consideration is given to residents who have experienced traffic noise impacts for
long periods of time.
3. Absolute Predicted Build Noise Level (State funded only criterion). The
predicted future build noise levels are at least 66 dBA. More consideration should
be given to areas with higher absolute traffic noise levels. Absolute noise levels
typically found along highways, 60-75 dBA, are deemed undesirable and cause
complaints from adjacent residents. In general, the higher the absolute noise, the
more complaints.
4. Relative Predicted Build Noise Level (State funded only criterion). The
predicted future build noise levels are at least 10 dBA greater than the existing
noise levels. More consideration is given to areas with larger increases over
existing noise levels. This gives greater consideration to projects for highways on
new location and major reconstruction than it does to projects of smaller
magnitude. For most people, a 3 dBA increase is barely perceptible, a 5 dBA
increase is readily perceptible, and a 10 dBA increase doubles the perceived
loudness of the noise.
5. Build vs. No-Build Noise Levels (State funded only criterion). The future build
noise levels are at least 5 dBA greater than the future no-build noise levels. More
consideration should be given to areas where larger changes in traffic noise
levels are expected to occur if the project is constructed than if it is not.
Alaska EPM Noise Policy 19 April 2011 6. Land use (State funded only criterion). Land use is not changing rapidly and
there are local ordinances or zoning in place to control the new development of
noise sensitive land uses adjacent to transportation corridors.
Noise Abatement Recommendation Worksheet
A noise abatement recommendation worksheet (Appendix B) will be filled out for each
noise receptor in the noise study. The Regional Environmental Manager will approve
and sign the worksheets. If an abatement measure is determined not feasible, then the
reasonableness analysis section of the Worksheet does not need to be completed.
Likewise, if it determined that the abatement measure is not reasonable, the feasibility
portion of the checklist will not have to be filled out. DOT&PF will only implement a
noise abatement measure if it has been determined both feasible and reasonable. The
Regional Environmental Manager will recommend or not recommend that a noise
abatement measure be implemented. The recommendation worksheet will be
submitted to the Project Manager (PM) who will sign the recommendation worksheet. If
the PM does not approve the recommendation then the Preconstruction Engineer will
resolve the dispute. The Preconstruction Engineer only needs to sign the noise
abatement recommendation worksheet if quiet pavements are recommended as
abatement on State-funded projects. The Regional Environmental Manager will ensure
that the recommendation is included in the project’s environmental document.
NOISE ANALYSIS REPORT
The results of the noise analysis will be presented in noise analysis report. The report
will discuss the purpose of the study, the methods utilized, the results of the study, any
proposed mitigation recommendations and a statement of likelihood. The noise analysis
will be appended to the environmental document. The following general format will be
followed for noise analysis reports.

During the detailed design of the proposed project, the recommendations for noise
abatement made in the environmental document will be reevaluated to determine if they
are still valid. If it is determined that any noise abatement measure recommendation is
no longer valid, then the affected public will be notified and the environmental document
reevaluated or supplemented as appropriate.
NOISE ABATEMENT MEASURE REPORTING PER 23 CFR772.13(f)
DOT&PF will maintain an inventory of all constructed noise abatement measures and
report to FHWA per the requirements of 23 CFR 772.13(f).The inventory shall include
the following parameters:
1) Type of abatement and cost (overall cost, unit cost per/sq. ft.);
2) Average height;
3) Length;
4) Area;
5) Location (state, city, route);
6) Year of construction;
7) Average insertion loss/noise reduction as reported by the model in the noise analysis;
NAC category(s) protected;
8) Material(s) used (precast concrete, berm, lock, cast in place concrete, brick, metal,
wood, fiberglass, combination, plastic (transparent, opaque, other); features (absorptive,
reflective, surface texture); foundation (ground mounted, on structure); project type
(Type I, other federal funding, state funding, local funding).
INFORMATION REQUIRED FOR NEPA DECISION
Prior to CE approval or issuance of a FONSI or ROD for a Type I project, the DOT&PF
must identify,


The noise abatement measures that are feasible and reasonable, and are likely
to be incorporated into the project; Noise impacts for which no abatement
appears to be feasible and reasonable; and
The NEPA documentation shall identify the locations where noise impacts will
occur, where noise abatement is feasible and reasonable, and the locations that
have no feasible and reasonable abatement.
Alaska EPM Noise Policy 21 April 2011 Statement of likelihood The statement of likelihood should identify the preliminary
locations of feasible and reasonable abatement and a statement that the final noise
abatement recommendation will be made after the final design and public involvement
processes are complete. This statement of likelihood will be included in all NEPA
documentation and noise analyses reports:
“As a result of the feasibility and reasonableness analysis conducted as a part of
the environmental document, the DOT&PF proposes to incorporate the following
noise abatement measures (type, locations) into the proposed project. These
noise abatement recommendations are preliminary and based upon the
feasibility and reasonableness analysis completed at the time the environmental
document. Final recommendations for noise abatement will be based upon the
feasibility and reasonable analysis conducted during the detailed design of the
project. Any changes in the final abatement recommendations will result in the
reevaluation of the approved NEPA document and the solicitation of additional
public comment”.
THIRD PARTY FUNDING OF NOISE ABATEMENT
For federal projects, third party funding CANNOT be used to make up the difference in
cost between the reasonable cost allowance and the actual cost. Third party funding
can only be used to pay for additional features such as landscaping, aesthetic
treatments, etc. for noise barriers that meet cost-effectiveness criteria.
FEDERAL PARTICIPATION FOR TYPE I FEDERAL PROJECTS
Federal Funds may be used for Noise Abatement measures when traffic noise impacts
have been identified, and abatement measures have been determined to be feasible
and reasonable pursuant to 23 CFR 772.13(d).
The following noise abatement measures may be considered for incorporation into a
Type I project to reduce traffic noise impacts. The costs of such measures may be
included in federal-aid participation project costs with the federal share being the same
as that for the system on which the project is located.
(1) Construction of noise barriers, including acquisition of property rights, either
within or outside the highway right-of-way. Landscaping is not a viable noise
abatement measure.
(2) 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.
(3) Alteration of horizontal and vertical alignments.
Alaska EPM Noise Policy 22 April 2011 (4) Acquisition of real property or interests therein (predominantly unimproved
property) to serve as a buffer zone to preempt development which would be
adversely impacted by traffic noise.
(5) Noise insulation of Activity Category D land use facilities listed in Table 1.
Post-installation maintenance and operational costs for noise insulation are not eligible
for federal-aid funding.
Quieter pavement is currently not listed in federal regulations (23 CFR 772) as a noise
abatement measure for which federal funding may be used. Consequently, quiet
pavements cannot be used as noise abatement on federal-aid projects.
DOT&PF may consider quieter pavement to reduce traffic noise on a state-funded
project. However, the decision to provide such a measure will be decided by the
Preconstruction Engineer as described elsewhere in this policy.
INFORMATION FOR LOCAL OFFICIALS
In an effort to prevent future traffic noise impacts on currently undeveloped lands and to
maintain compatibility between highways and future development, DOT&PF will inform
local officials whose jurisdiction is within the highway project of the best estimation of
future noise levels for both developed and undeveloped properties in the immediate
vicinity of the project. In addition, information on federal-aid, non-eligibility of noise
abatement for lands permitted for development after the date of public knowledge will
also be provided to local officials. This usually will be accomplished by providing a copy
of either the project’s noise analysis or the approved environmental document to the
local government. This information may also be provided through the plat review
process.
CONSTRUCTION NOISE
For all Type I Federal and State Projects, it is the policy of DOT&PF to:
(a) Identify land uses or activities that may be affected by noise from construction
of the project. The identification is to be performed during the project
development studies.
(b) Determine the measures that are needed in the plans and specifications to
minimize or eliminate adverse construction noise impacts to the community.
This determination shall include a weighing of the benefits achieved and the
overall adverse social, economic, and environmental effects and costs of the
abatement measures.
(c) Incorporate the needed abatement measures in the plans and specifications.
The Regional Environmental Manager will work with the Design Engineering Manager to
reduce construction noise by requiring the contract specifications include the statement
that all construction equipment be properly maintained and have mufflers in acceptable
working condition. In the event that construction noise complaints occur during the
Alaska EPM Noise Policy 23 April 2011 course of construction activities, measures will be taken by the Construction Project
Engineer to resolve the problem to the extent practical. Measures might include locating
stationary construction equipment as far from nearby noise sensitive receivers as
possible, shutting off idling equipment, rescheduling construction operations to avoid
periods of noise annoyance, notifying nearby residents whenever extremely noisy
operations will be occurring, and installing permanent or portable acoustic abatement
measures around stationary construction noise sources.
In some cases there are no alternatives to conducting construction activities during the
night, on weekends, or on holidays. When deemed necessary, the Department will
make every effort to notify the public prior to conducting these activities. The public
involvement in these cases should occur during design and throughout the construction
duration. In some communities, local ordinances may restrict noise generating activities.
Where this is the case, the Department and its contractor will comply with local noise
ordinances and acquire any necessary noise permits for these activities prior to their
initiation.
STATE-FUNDED PROJECTS
In general, the same methods are followed in the identification of noise impacts for
state-funded projects and federal-aid projects. Results of noise analyses will be
documented in the State Projects Environmental Checklist. If noise abatement is
determined to be feasible and reasonable, then the Regional Environmental Manager
will make a recommendation to the Preconstruction Engineer. The Preconstruction
Engineer will decide whether the recommended abatement measure will be
constructed. Abatement will be provided only if it meets the feasibility and
reasonableness criteria of this policy and the state funded appropriation can
accommodate this expenditure.
SUPERCEDENCE
This policy is effective upon signature and replaces the Department’s March 1996 Noise
Policy and the April 2009 Traffic Noise Abatement Guidance. This policy is applicable
to any project that does not have an approved NEPA document prior to its
implementation.
