1.0 INTRODUCTION

The City of Oshawa has initiated a Schedule C Municipal Class Environmental Assessment

(Class EA) to improve Conlin Road East between Simcoe Street North and Townline Road

North in the City of Oshawa, Ontario. AMEC Environment & Infrastructure, a Division of AMEC

Americas Limited (AMEC) has been retained by the City to complete the Class EA. This traffic

noise impact assessment report is prepared to support the Municipal Class EA process.

The objective of the study is to predict future “build” and future “no-build” sound levels from road

traffic in the area (i.e., noise levels with and without the proposed project taking place); to

assess potential noise impacts according to the applicable guidelines; to specify mitigation

measures where required; and to assess potential construction noise and provide a Code of

Practice to minimize construction noise impacts.

A glossary of commonly used noise terminology can be found in Appendix A.

1.1 Project Description (Nature of the Undertaking)

Conlin Road East is classified as an arterial roadway and is under the jurisdiction of the City of

Oshawa. The proposed improvements include widening of Conlin Road East from Simcoe

Street North to Grandview Street North to a four-lane road, urbanization of Conlin Road East

from Grandview Street North to Townline Road North, and constructing roundabouts on Conlin

Road East at Wilson Road North and Grandview Street North. The project limits are shown in

Figure 1.

1.2 Study Area (Area of Investigation)

In accordance with the Ministry of Transportation of Ontario (MTO) and the Ministry of

Environment (MOE) practices, the area of investigation for the project has been determined

using screening level modeling. The area of investigation is estimated as the closest setback

distance where noise from the future build roadway is equal to future ambient plus 5 dB. This

represents a 5 dB change from future ambient conditions. The Area of Investigation is

calculated for the Conlin Road East improvements and the calculation is included in

Appendix B.

For this project, the calculated Area of Investigation is 80 m on either side of Conlin Road East.

The Area of Investigation is shown in Figures 2 through 9.


TP113039 Page 2

2.0 ROAD TRAFFIC NOISE IMPACTS (OPERATIONAL NOISE)

For surface transportation projects, noise from the operation of a project following its completion

is of primary concern. This section of the report provides an evaluation of noise impacts from

road traffic noise resulting from the project.

2.1 Applicable Guidelines

There are several transportation noise guidelines that are applicable to this project. Ontario

Provincial policies established by the MTO and MOE are directly applicable under the Municipal

Class EA process for transportation projects, and are discussed in detail in this report. The City

of Oshawa does not have noise guidelines applicable to this project. The Region of Durham

Noise Abatement Policy (2012-W83) is applicable only to the installation and maintenance of

noise attenuation barriers associated with the regional road expansion projects, and therefore,

is not applicable to this project.

2.1.1 Ontario Provincial Guidelines and Policies

Ontario has a number of guidelines and documents related to assessing road traffic noise

impacts applicable to Conlin Road East. These documents and policies include:

Ontario MTO, Environmental Guide For Noise (MTO 2006); and

Ontario MTO, Environmental Reference for Highway Design (MTO 2002).

These guidelines apply to major roadway construction and reconstruction of municipal roads,

provincial highways and freeways. The Environmental Guide for Noise updates, improves and

supersedes both the MOE/MTO “Joint Protocol” (MTO & MOE, 1986) and the MTO Quality and

Standards Directive QST-A1 (MTO 1992a).

The Environmental Office Manual, Environmental Reference for Highway Design, and Draft

Environmental Guide for Noise are all MTO documents that serve as detailed technical

references for assessing vehicular road traffic noise on provincial highways in Ontario. All these

MTO documents have been considered in the preparation of the road traffic noise impact

outlined below.

Under the Environmental Guide for Noise, the importance of changes from a noise impact

perspective is based on the objective level and change from existing conditions. Assessments

should be based on a minimum 10-year future horizon year traffic data (i.e., on traffic volumes

10 years after the completion of the project). For this project, traffic data for years 2016, 2021

and 2031 are available, and the data for 2031 is considered for this assessment.

Noise mitigation is warranted when sound levels are increased to 65 dBA or the increase is

5 dB over the “no-build” ambient (MTO Environmental Guide for Noise). Mitigation measures

can include noise barriers, noise reducing asphalts, and changes in vertical profiles and


TP113039 Page 3

horizontal alignments. Noise mitigation where applied must be administratively, economically

and technically feasible, and must provide at least 5 dB of reduction averaged over the first row

of noise-sensitive receivers. Mitigation measures are restricted to within the roadway right-of-

way. Off right-of-way noise mitigation, such as window upgrades and air conditioning, is not

considered for this assessment as the assessment is for done for the Outdoor Living Area

(OLA). Noise mitigation requirements per MTO guidelines are summarized in Table 1.

Table 1: Summary of Mitigation Efforts under Ontario Road Traffic Noise Guidelines

Change in Sound Levels above Ambient and Absolute Future

Sound Levels with Project Mitigation Effort Required

<5 dB Increase OR <65 dBA Absolute

None

>5 dB Increase OR >65 dBA Absolute

Investigate noise control measures within right-of-way

Noise control measures where used must provide a minimum of 5 dB of attenuation, averaged over the first row of receivers or 3 dB of attenuation over the first row of affected receivers for upgrading existing measures

Mitigated to as close to ambient as possible, where technically, economically and administratively feasible

Note: Values are Leq (16h) levels for municipal and Provincial Highways, and Leq (24h) for Freeways

Under MTO and MOE policies, Leq (24h) sound levels are used to assess impacts from

freeways (400-series major highways), and daytime Leq (16h) sound levels are used to assess

impacts from all other Provincial highways and Municipal roadways. As this project is a

municipal arterial road, Leq (16h) values have been used for the assessment.

2.2 Location of Noise Sensitive Areas within the Area of Investigation

2.2.1 Definition of Noise Sensitive Areas

Noise impacts from transportation projects are evaluated at noise sensitive receptors within the

area. Noise receptors are called “Noise Sensitive Areas (NSAs)” in the MTO documents. Under

current Ontario guidelines, NSAs include the following land uses, provided they have an outdoor

living area associated with them:

Private homes (single family units and townhouses);

Multiple unit buildings such as apartments, provided they have a communal OLA

associated with them;

Hospitals and nursing homes for the aged, provided they have an OLA for use by

patients; and

Campgrounds that provide overnight accommodation.


TP113039 Page 4

The following land uses are generally not considered to qualify as NSAs:

Apartment balconies;

Educational facilities and daycare centres where there are OLAs for students (except

dormitories with OLA);

Churches and other places of worship;

Cemeteries;

Parks and picnic areas not part of a defined OLA;

All commercial; and

All industrial.

2.2.2 Future Land Uses

Lands that have been zoned for future noise sensitive uses and have an approved Plan of

Subdivision in place, but where NSAs do not currently exist must also be considered under

MOE policies. A review of the land use zoning within the project Area of Investigation has been

conducted for this assessment and the following subdivisions have been identified and

considered in this assessment:

Development between Wilson Road North and west of Harmony Road North on south of

Conlin Road East;

Development east of Grandview Road North on south of Conlin Road East; and

Development west of Townline Road North on south of Conlin Road East.

Noise barrier height proposed for the developments are considered in the assessment and their

height and location are provided in Appendix C.

2.2.3 Location and Number of Noise Receptors within the Area of Investigation

Two hundred and forty eight (248) single family homes are identified as noise receptors in the

study area and that includes one hundred and thirty three (133) existing houses and one

hundred and fifteen (115) future houses. Total of eleven (11) representative noise receptors are

modelled in this assessment to represent all the houses identified within the study area,

including future houses. The noise receptors considered in the noise modelling and the

representative noise receptor locations are shown in Figures 2 through 9, and they are

described in Table 2.

A site visit was conducted by AMEC staff on March 12, 2014. The existing noise barrier/berm

combination in the backyard of the houses on Secretariat Place and Norland Circle (NR01) were

identified during the site and are included in the assessment. The fence in the backyard of the

house south of Conlin Road East, just west of Walreg Drive is a semi private type and is not

considered as a noise barrier in this assessment (NR02). However, the wooden fence in the

backyard of the houses east of Walreg Drive is considered to be a noise barrier. The existing

noise barriers in the backyard of the house on Elmwood Court (NR04) and Valewood Court

were identified during the site and are included in the assessment. The existing barrier height

ranges from about 1.8 m to 2.2 m. The existing barrier height and location for the dwellings as

provided in the subdivision noise study are provided in Appendix C.

2.3 Road Traffic Data

The assessment is completed based on minimum 10-year future horizon year traffic data

(i.e., on traffic volumes 10 years after the completion of the project). Accordingly, a design year

of 2031 is considered for the assessment of this project.

Projected future ‘build’ traffic and ‘no-build’ traffic volumes, traffic split between passenger cars

and trucks, and posted traffic speed were provided by the traffic consultant for the project

(Paradigm Transportation Solutions Ltd).


TP113039 Page 6

Traffic data was provided in the form of Peak AM and PM hourly traffic volumes, and the Annual

Average Daily Traffic (AADT) was calculated from the peak hour traffic assuming that the peak

hour is 10% of the AADT. Traffic split between day and night was done based on MOE’s traffic

volume projection guideline (90% / 10%). The breakdown of commercial vehicles into heavy

trucks and medium trucks was assumed to be proportional to the 55% / 45%. The traffic data

used in the assessment is summarized in Tables 3 and 4.

2.4 Noise Model Used

Traffic noise modelling for both future “no-build” and future “build” cases were completed

following the MOE ORNAMENT noise procedure, using the MOE STAMSON noise model.

STAMSON accounts for various traffic types and speeds, source-receiver distances, receiver

heights, the presence of building “rows” and accounts for the effectiveness of noise barriers.


TP113039 Page 8

The following factors were taken into account in the analysis:

Horizontal and vertical road-receiver geometry;

Road gradients;

Intervening terrain types (ground absorption);

Traffic volumes and percentage of trucks;

Vehicle speeds; and

Screening provided by houses and existing sound barriers.

Distances and receptor locations were obtained from plan drawings and existing sound barrier

information was used from photographs, noise study for the subdivision and notes taken during

the site visit conducted by AMEC staff. A copy of the proposed project layout is provided in

Appendix D.

2.5 Determination of Potential Impacts

Under the Joint Protocol and MTO Environmental Guide for Noise, the assessment of impact is

conducted by comparing future “build’ sound levels (with the project in place) with future

“no-build” sound levels. Table 5 presents a comparison of future “build” versus future “no-build”

sound levels.

The results indicate that the representative receptors NR01 through NR11 are in compliance

with the MTO noise guidelines. Therefore, investigation of noise mitigation is not required.

3.0 CONSTRUCTION NOISE IMPACTS

Construction noise impacts are temporary in nature, and largely unavoidable. With adequate

controls, impacts can be minimized. However, for some periods of time and types of work,

construction noise will be noticeable at some receptor locations. This section of the report

provides an evaluation of noise impacts from construction resulting from the undertaking, and

discusses guideline and Code of Practice requirements to minimize impacts.

3.1 Construction Noise Guidelines

3.1.1 Local Noise Control Bylaws

The proposed project is under the jurisdiction of the City of Oshawa and the Region of Durham.

The City’s Noise By-law (No. 112-82) is applicable to the project. The City’s noise bylaw

restricts noise, specifically from construction activities to the daytime period (7:00 one day to

19:00 next day and 9:00 to 17:00 on Sundays).

3.1.2 MOE Model Municipal Noise Control Bylaw

The MOE stipulates limits on noise emissions from individual items of equipment, rather than for

overall construction noise. In the presence of persistent noise complaints, sound emission

standards for the various types of construction equipment used on the project should be verified

to ensure that they meet the specified limits contained in MOE Publication

NPC-115 “Construction Equipment”, as follows (MOE 1977b) (Table 7).

Table 7: NPC-115 Maximum Noise Emission Levels for Typical Construction Equipment

Type of Unit Maximum Sound Level[1]

(dBA) Distance (m) Power Rating (kW)

Excavation Equipment[2] 83 15 Less than 75 kW

85 15 75 kW or Greater

Pneumatic Equipment[3] 85 7 -

Portable Compressors 76 7 -

Notes: [1] Maximum permissible sound levels presented here are for equipment manufactured after Jan. 1, 1981 [2] Excavation equipment includes bulldozers, backhoes, front end loaders, graders, excavators, steam rollers and other

equipment capable of being used for similar applications [3] Pneumatic equipment includes pavement breakers

3.2 Anticipated Construction Activities

The following construction activities are anticipated as part of this project:

Construction and rehabilitation of the base course;

Addition of new lane(s); and

Paving (and repaving) of the roadway surface.


TP113039 Page 11

3.3 Anticipated Construction Noise Levels

Construction activities will vary temporarily and spatially as the project progresses. Noise levels

from construction at a given receptor location will also vary over time as different activities take

place, and as those activities change location within the right-of-way.

At this time, a detailed construction plan is not available. An analysis of potential worst-case

construction noise levels for the aforementioned activities has been conducted based on

generic data (equipment types and activities). The analysis of construction noise was completed

and a sound level in the range of 65-81 dBA is expected at the modelled receptors. The

construction sound level calculations are provided in Appendix F.

3.4 Construction Code of Practice Requirements (Mitigation)

To minimize the potential for construction noise impacts, it is recommended that provisions be

written into the contract documentation for the contractor, as outlined below:

All equipment should be properly maintained to limit noise emissions. As such, all

construction equipment should be operated with effective muffling devices that are in

good working order.

There should be explicit indication that Contractors are expected to comply with all

applicable requirements of the contract and local noise by-laws. Enforcement of noise

control by-laws is the responsibility of the Municipality for all work done by Contractors.

The Contract documents should contain a provision that any initial noise complaint will

trigger verification that the general noise control measures agreed to are in effect.

In the presence of persistent noise complaints, all construction equipment should be

verified to comply with MOE NPC-115 guidelines, as outlined in Section 3.

In the presence of persistent complaints and subject to the results of a field investigation,

alternative noise control measured may be required, where reasonably available. In

selecting appropriate noise control and mitigation measures, consideration should be

given to the technical, administrative and economic feasibility of the various alternatives.


TP113039 Page 12

4.0 CONCLUSIONS AND RECOMMENDATIONS

The potential environmental noise impacts of the Conlin Road East improvements between

Simcoe Street North and Townline Road North have been assessed. Both operational and

construction noise impacts have been considered in this assessment. The sound levels

predicted at representative noise receptors NR01 through NR11 are expected to meet the

applicable MTO guideline noise limits. Therefore, additional noise mitigation is not required and

has not been investigated for this improvement.

Construction noise impacts are temporary in nature but will be noticeable at times at residential

receptors. Methods to minimize construction noise impacts should be included in the

Construction Code of Practice, as outlined in the Section 3.4.

APPENDIX A

GLOSSARY OF COMMONLY USED NOISE TERMINOLOGY

of 4

APPENDIX A: BACKGROUND INFORMATION ON NOISE Ambient or Background Noise: The ambient noise from all sources other than the sound of interest (i.e. sound other than that being measured). Under most MOE guidelines, aircraft overflights and train noise, due to their transient nature, are normally excluded from measurements of background noise. Attenuation: The reduction of sound intensity by various means (e.g., air, humidity, porous materials, etc.). dB - Decibel: The logarithmic units associated with sound pressure level, sound power level, or acceleration level. See sound pressure level, for example. dBA - Decibel, A-Weighted: The logarithmic units associated with a sound pressure level, where the sound pressure signal has been filtered using a frequency weighting that mimics the response of the human ear to quiet sound levels. The resultant sound pressure level is therefore representative of the subjective response of the human ear. A-weighted sound pressure levels are denoted by the suffix ‘A’ (ie. dBA), and the term pressure is normally omitted from the description (i.e., sound level or noise level).

dBC - Decibel, C-Weighted: The logarithmic units associated with a sound pressure level, where the sound pressure signal has been filtered using a frequency weighting that mimics the response of the human ear to loud sound levels. C-weighted sound pressure levels are denoted by the suffix ‘C’ (ie. dBC). C-weighted levels are often used in low-frequency noise analysis, as the filtering effect is nearly flat at lower frequencies. dBL or dBLin - Decibel, Linear: The logarithmic units associated with a sound pressure level, where the sound pressure signal is unfiltered, and represents the full spectrum of incoming noise. Calibrator (Acoustical): A device which produces a known sound pressure on the microphone of a sound level measurement system, and is used to adjust the system to standard specifications.

Directivity Factor (Q) (also, Directional or Directionality Factor): A factor mathematically related to Directivity Index, used in calculating propagated sound levels to account for the effect of reflecting surfaces near to the source. For example, for a source in free space where the sound is radiating spherically, Q = 1. For a source located on or very near to a surface (such as the ground, a wall, rooftop, etc.), where the sound is radiating hemi-spherically, Q = 2. This accounts for the additional sound energy reflecting off the surface, and translates into a +3 dB add. Energy Equivalent Sound Level (Leq): An energy-average sound level taken over a specified period of time. It represents the average sound pressure encountered for the period. The time period is often added as a suffix to the label (e.g., Leq(24) for the 24-hour equivalent sound level). Leq is usually A-weighted. An Leq value expressed in dBA is a good, single value descriptor of the annoyance of noise. Exceedance Noise Level (LN): The noise level exceeded N% of the time. It is a statistical measure of the noise level. For highly varying sounds, the L90 represents the background noise level, L50 represents the median or typical noise level, and L10 represents the short term peak noise levels, such as those due to occasional traffic or a barking dog. Far Field: Describes a region in free space where the sound pressure level from a source obeys the inverse-square law (the sound pressure level decreases 6 dB with each doubling of distance from the source). Also, in this region the sound particle velocity is in phase with the sound pressure. Closer to the source where these two conditions do not hold constitutes the “near field” region. Free Sound Field (Free Field): A sound field in which the effects of obstacles or boundaries on sound propagated in that field are negligible. Frequency: The number of times per second that the sine wave of sound or of a vibrating object repeats itself, now expressed in hertz (Hz), formerly in cycles per second (cps). Hertz (Hz): Unit of measurement of frequency, numerically equal to cycles per second. Human Perception of Sound: The human perception of noise impact is an important consideration in qualifying the noise effects caused by projects. The following table presents a general guideline.

Increase in Noise Level (dB) Perception

3 or less insignificant due to imperceptibility

4 to 5 just-noticeable difference

6 to 9 marginally significant

10 or more significant, perceived as a doubling of sound exposure

of 4

Impact Sound: The sound produced by the collision of two solid objects, e.g., footsteps, dropped objects, etc., on an interior surface (wall, floor, or ceiling) of a building. Typical industrial sources include punch presses, forging hammers, etc. Impulsive Noise: a) Single or multiple sound pressure peak(s) (with either a rise time less than 200 milliseconds or total duration less than 200 milliseconds) spaced at least by 500 millisecond pauses, b) A sharp sound pressure peak occurring in a short interval of time. Infrasonic: Sounds of a frequency lower than 20 hertz. Insertion Loss (IL): The arithmetic difference between the sound level from a source before and after the installation of a noise mitigation measure, at the same location. Insertion loss is typically presented as a positive number, i.e., the post-mitigation sound level is lower than the pre-mitigation level. Insertion loss is expressed in dB and is usually specified per 1/1 octave band, per 1/3 octave band, or overall. Low Frequency Noise (LFN): Noise in the low frequency range, from infrasonic sounds (<20 Hz) up to 250 Hz. Masking: a) The process by which the threshold of audibility for a sound is raised by the presence of another (masking) sound, or b) The amount by which the threshold of audibility of a sound is raised by the presence of another (masking) sound. Near Field: The sound field very near to a source, where sound pressure does not obey the inverse-square law and the particle velocity is not in phase with the sound pressure. Noise: Unwanted sound. Noise Level: Same as Sound Level, except applied to unwanted sounds. Peak Sound Pressure Level: Same as Sound Pressure Level except that peak (not peak-to-peak) sound pressure values are used in place of RMS pressures. Quasi-Steady Impulsive Noise: Noise composed of a series of short, discrete events, characterized by rapid rise times, but with less than 0.5 seconds elapsing between events. RMS Sound Pressure: The square-root of the mean-squared pressure of a sound (usually the result of an RMS detector on a microphone signal). Reverberant Field: The region in a room where the reflected sound dominates, as opposed to the region close to the noise source where the direct sound dominates. Sound: a dynamic (fluctuating) pressure. Sound Exposure Level (SEL): An Leq referenced to a one second duration. Also known as the Single Event Level. It is a measure of the cumulative noise exposure for a single event. It provides a measure of the accumulation of sound energy over the duration of the event.

of 4

Sound Intensity: The sound energy flow through a unit area in a unit time. Sound Level Meter: An instrument comprised of a microphone, amplifier, output meter, and frequency-weighting networks which is used for the measurement of noise and sound levels. Sound Pressure Level (SPL): The logarithmic ratio of the RMS sound pressure to the sound pressure at the threshold of hearing. The sound pressure level is defined by equation (1) where P is the RMS pressure due to a sound and P0 is the reference pressure. P0 is usually taken as 2.0 × 10-5 Pascals. (1) SPL (dB) = 20 log(PRMS/P0) Sound Power Level (PWL): The logarithmic ratio of the instantaneous sound power (energy) of a noise source to that of an international standard reference power. The sound power level is defined by equation (2) where W is the sound power of the source in watts, and W0 is the reference power of 10-12 watts. (2) PWL (dB) = 10 log(W/W0) Interrelationships between sound pressure level (SPL) and sound power level (PWL) depend on the location and type of source. Spectrum: The description of a sound wave's resolution into its components of frequency and amplitude. Speed (Velocity) of Sound in Air: 344 m/s (1128 ft/s) at 70°F (21°C) in air at sea level. Threshold of Audibility (Threshold of Detectability): The minimum sound pressure level at which a person can hear a specified frequency of sound over a specified number of trials.
