Noise Feasibility Study, Proposed Residential Development Page 1 77 Victoria Road, Guelph, Ontario May 7, 2021 1 Introduction and Summary HGC Engineering was retained by 2601625 Ontario Inc. to conduct a noise feasibility study for a proposed residential development to be located at 77 Victoria Road in the City of Guelph, Ontario. The proposed development will consist of two blocks of 3-storey stacked townhouses. The study is required by the Municipality as part of their rezoning and approvals process. This study is being updated to reflect the City of Guelph’s comments, dated March 22, 2021, included in Appendix D as well as the updated site plan prepared by Astrid J. Clos Planning Consultants dated April 7, 2021. The primary source of transportation noise is road traffic on Victoria Road. Relevant road traffic data was obtained from City of Guelph personnel. The data was used to predict future traffic sound levels at the façades of the proposed dwelling units and in the outdoor amenity areas. The predicted sound levels were compared to the guidelines of the Ministry of the Environment, Conservation and Parks (MECP) and the City. The results of this study indicate that with suitable noise control measures integrated into the design of the buildings, it is feasible to achieve the indoor MECP guideline sound levels from road traffic sources. The recommended noise control measures include appropriate wall and window glazing assemblies, an alternative means of ventilation to open windows, and an acoustic barrier around outdoor amenity areas with sound level excesses. Warning clauses will need to be included in the property, tenancy and purchase and sale and/or rental agreements to warn occupants of potentially audible transportation noise levels and of the nearby institutional uses. An analysis was also conducted to determine the anticipated impact of stationary noise from rooftop units at the existing institutional building (St. James Catholic School) to the south of the subject site on the proposed dwelling units. Reasonable estimates of the size and tonnage of the rooftop mechanical units have been recorded based on observations on a site visit. A 3D computer model of the area was created, using acoustic modelling software and manufacturer’s sound power data. The model was used in the analysis to predict sound levels associated with the existing rooftop mechanical equipment at the proposed residential units.
Noise Feasibility Study, Proposed Residential Development Page 2 77 Victoria Road, Guelph, Ontario May 7, 2021 The results indicate that sound emissions from the existing institutional building at the closest sensitive receptors will be at or below the MECP minimum exclusionary sound level limits. Further, physical mitigation measures will not be required for the rooftop units associated with the existing institutional building. 2 Site Description and Sources of Sound Figure 1 shows a key plan which identifies the location of the proposed residential development at the east side of Victoria Road, south of Cassino Avenue, specifically at 77 Victoria Road in the City of Guelph, Ontario. The concept plan prepared by Astrid J. Clos Planning Consultants dated April 7, 2021 is included as Figure 2a. The proposed development will consist of two blocks of 3-storey stacked townhouses. A site visit was conducted by HGC Engineering personnel on September 4, 2020 to make observations of the acoustic environment and to identify the significant noise sources in the vicinity. During the site visit, it was noted that the primary source of sound impacting the site is vehicular traffic on Victoria Road. The site is currently occupied by low-rise buildings which will be removed to make way for the proposed development. The surrounding area mainly consists of residential and institutional lands. Existing residential uses are located to the north, east and west. St. James Catholic School is located to the south. There are HVAC units on the roof of the existing school building and these have been included in the noise assessment. A noise warning clause is recommended in Section 3.4 to inform future occupants of the nearby institutional facilities in the area and that sounds may be audible at times. The subject site is considered to be in a Class 2 area as per correspondence with City of Guelph personnel.

3 Road Traffic Noise Assessment
3.1 Road Traffic Noise Criteria
Guidelines for acceptable levels of road traffic noise impacting residential developments are given in
the MECP publication NPC-300 “Environment Noise Guideline Stationary and Transportation
sources – Approval and Planning”, release date October 21, 2013, and are listed in Table I below.
The City of Guelph Noise Control Guidelines version 1.0 effective January 1, 2019 were also used in
conjunction with NPC-300. The values in Table I are energy equivalent (average) sound levels [LEQ]
in units of A-weighted decibels [dBA].
Table I: Road Noise Criteria (dBA)
Daytime LEQ(16 hour) Nighttime LEQ(8 hour)
Area
Road Road
Outdoor Living Areas 55 dBA --
Inside Living/Dining Rooms 45 dBA 40 dBA
Inside Bedrooms 45 dBA 40 dBA
Daytime refers to the period between 07:00 and 23:00, while nighttime refers to the period between
23:00 and 07:00. The term "Outdoor Living Area" (OLA) is a noise sensitive space intended for the
quiet enjoyment of the outdoor environment and is readily accessible from the building. OLA’s
include backyard and side yard areas of single family, semi-detached and townhouse dwellings,
gardens, terraces and patios, balconies and elevated terraces (e.g. Rooftops) that are not enclosed
with a minimum depth of 4 meters and common outdoor areas associated with high-rise and other
multi-unit buildings and passive recreational areas such as parks if identified by the City. Front yards
areas are not OLA’s.
The target sound level in an OLA is 55 dBA. The guidelines in the MECP publication allow the
sound level in an Outdoor Living Area to be exceeded by up to 5 dBA, without mitigation, if
warning clauses are placed in the purchase and rental agreements to the property. Where OLA sound
levels exceed 60 dBA, physical mitigation is required to reduce the OLA sound level to 55 dBA.
Where mitigation is not technically, economically and administratively feasible, an excess above the
limit of 55 dBA is acceptable with the use of a noise warning clause with some justification.Noise Feasibility Study, Proposed Residential Development Page 4 77 Victoria Road, Guelph, Ontario May 7, 2021 A central air conditioning system as an alternative means of ventilation to open windows is required for dwellings where nighttime sound levels outside bedroom or living/dining room windows exceed 60 dBA or daytime sound levels outside bedroom or living/dining room windows exceed 65 dBA. Forced-air ventilation with ducts sized to accommodate the future installation of air conditioning is required when nighttime sound levels at bedroom or living/dining room windows are in the range of 51 to 60 dBA or when daytime sound levels at bedroom or living/dining room windows are in the range of 56 to 65 dBA. Building components such as walls, windows and doors must be designed to achieve indoor sound level criteria when the plane of window nighttime sound level is greater than 60 dBA or the daytime sound level is greater than 65 dBA due to road traffic noise. Warning clauses are required to notify future residents of possible sound level excesses when nighttime sound levels exceed 50 dBA and/or daytime sound levels exceed 55 dBA in the outdoor living area and at the plane of the bedroom or living/dining room window due to road traffic. 3.2 Traffic Noise Predictions 3.2.1 Road Traffic Data Road traffic data for Victoria Road was obtained from the City of Guelph in the form of turning movement counts and is provided in Appendix A. The data was projected ten years from the anticipated occupation date to the year 2035 using a conservative estimate of 2.5% growth per year. A commercial vehicle percentage of 4.4% medium trucks and 3.4% heavy trucks was calculated. A posted speed limit of 50 km/h was applied. A day-night split of 90%/10% was used, as per ORNAMENT (Ontario Road Noise Analysis Method for Environment and Transportation), a document describing modelling procedures for the prediction of road traffic noise prepared by the MECP, for municipal roadways. Table II below indicates the road traffic data used in the analysis. Road traffic information is included in Appendix A along with sample calculations.

3.2.2 Road Traffic Noise Predictions
To assess the levels of road traffic noise which will impact the site in the future, predictions were
made using STAMSON version 5.04, a computer algorithm developed by the MECP. All
STAMSON outputs are included in Appendix B.
The predictions were performed at the top storey of the proposed buildings (receiver height of 7.5 m)
during daytime and nighttime hours to investigate ventilation requirements and in the outdoor
amenity areas (rear yards and ground floor common amenity area) to determine acoustic barrier
requirements. The distance setbacks of the proposed buildings from the roads indicated on the site
plan and aerial photos were used in the analysis. Sample distances are shown on Figure 2a.
Reflective ground has been applied in the STAMSON calculations for A to D. The results of these
predictions are summarized in Table III. The acoustic requirements may be subject to modifications
if the site plan is changed significantly.

Recommendations are provided in the following sections. 3.3.1 Outdoor Living Areas The predicted sound level at the rear yard of the townhouse unit with flanking exposure to Victoria Road (Prediction Location [A]) will be up to 66 dBA, 11 dBA in excess of the MECP’s limit of 55 dBA. An acoustic barrier 2.0 m in height will reduce the sound level in this area to less than 60 dBA. The wall component of the barrier should be of a solid construction with a surface density of no less than 20 kg/m2. The walls may be constructed from a variety of materials such as wood, brick, pre-cast concrete or other concrete/wood composite systems provided that it is free of gaps or cracks, non-combustible, resistant to graffiti or include a graffiti resistant coating confirming to ASTM standards, vermin and fungi resistant, and has a minimum predicted lifespan of 20 years. The final material will need to be approved by the City of Guelph. The sound level at the rear yard of the townhouse unit with some exposure to Victoria Road (Prediction Location [B]) will be up 64 dBA, 9 dBA in excess of the MECP’s limit of 55 dBA. The implementation of the 2.0 m high acoustic barrier at the rear yard of the dwelling unit with flanking exposure to Victoria Road (Prediction Location [A]) will reduce sound levels in this area to less than 60 dBA. The predicted daytime sound levels in the interior common amenity area (Prediction Location [D]) will be 59 dBA, 4 dBA in excess of the MECP’s limit. The implementation of the 2.0 m high acoustic barrier at the rear yard of the dwelling unit with flanking exposure to Victoria Road (Prediction Location [A]) will further reduce sound levels in this area. The above grade units have balconies less than 4 m in depth. These balconies are not considered as outdoor living areas under MECP guidelines, and therefore are exempt from traffic noise assessment.
Noise Feasibility Study, Proposed Residential Development Page 7 77 Victoria Road, Guelph, Ontario May 7, 2021 3.3.2 Indoor Living Areas and Ventilation Requirements Central Air Conditioning The predicted sound levels at the top-storey façades of the proposed dwelling units with flanking exposure to Victoria Road (Prediction Location [A]) will be greater than 60 dBA during the nighttime and 65 dBA during the daytime. To address these excesses, the MECP guidelines recommend that the proposed dwelling units be equipped with central air conditioning. Provision for the Future Installation of Air Conditioning The predicted sound levels at the top-storey façades of the remaining dwelling units (Prediction Locations [B] and [C]) will be between 56 and 65 dBA during the daytime and between 51 and 60 dBA during the nighttime. The proposed buildings will require an alternative means of ventilation to open windows. The use of central air conditioning will exceed this requirement. The guidelines also recommend warning clauses for these dwelling units. These units are indicated in Figure 2b. Window or through-the-wall air conditioning units are not recommended for any residential units because of the noise they produce and because the units penetrate through the exterior wall which degrades the overall noise insulating properties of the envelope. The location, installation and sound ratings of the outdoor air conditioning devices should minimize noise impacts and comply with criteria of MECP publication NPC-300, as applicable. 3.3.3 Building Façade Constructions Future road traffic sound levels at the plane of windows of dwelling units with flanking exposure to Victoria Road (prediction location [A]) will be greater than 60 dBA during the nighttime. MECP guidelines recommend that the windows, walls and doors be designed so that the indoor sound levels comply with MECP noise criteria. Calculations have been performed to determine the building envelope construction likely to be required to maintain indoor sound levels within MECP guidelines. The calculation methods were developed by the National Research Council (NRC). They are based on the predicted future sound levels at the building facades and the anticipated area of the façade components (walls, windows and doors) relative to the floor area of the adjacent room. The minimum necessary specification for the building envelope of the dwelling units with flanking
Noise Feasibility Study, Proposed Residential Development Page 8 77 Victoria Road, Guelph, Ontario May 7, 2021 exposure to Victoria Road (prediction location [A]) is Acoustical Insulation Factor, AIF-29 for living/dining rooms and AIF-27 for bedrooms, based on the possibility of sound entering the building through walls and windows. As a general guideline, a glazing construction with two panes of 3 mm glass and 13 mm airspace with an STC rating of 30 will be sufficient for the dwelling unit as long as the window to floor area ratio does not exceed 32% for living/dining room and 50% for bedroom windows. If the patio doors are to be used in the dwelling, they must be included in the window area. Further Analysis When detailed floor plans and building elevations are available for the dwelling unit adjacent to Victoria Road (prediction location [A]), an acoustical consultant should provide revised glazing construction based on actual window to floor area ratios. The remaining dwelling units in the development will have predicted sound levels less than 65 dBA during the daytime and less than or equal to 60 dBA during the nighttime. Thus, any exterior wall and double glazed window construction meeting the minimum requirements of the OBC will provide adequate sound insulation. 3.4 Warning Clauses The MECP and City of Guelph guidelines recommend that warning clauses be included in the property and tenancy agreements and offers of purchase and sale for all units with anticipated road traffic sound levels excesses. Wording from the City of Guelph Noise Control Guidelines is included in Appendix C and provided below. The city requires the following general clause to be included for all units. General (Gen): The Transferee covenants with the Transferor that the below clause, verbatim, will be included in all subsequent Agreements of Purchase of sale or lease and Sale and Deeds conveying the lands described herein, which covenant shall run with the said lands and is for the benefit of the subsequent owners and renters of the said lands and the owner of the adjacent road.
Noise Feasibility Study, Proposed Residential Development Page 9 77 Victoria Road, Guelph, Ontario May 7, 2021 Wording for all dwelling units (Units 1 – 18) with sound level excesses is given below. Note that the unit number in “Unit [XX]” will change depending on the proposed residential suite considered. Type A: The Transferee of Unit [XX], for himself, his heirs, executors, administrators, successors, and assigns acknowledge being advised that despite the inclusion of noise control features in the development and/or within the building unit sound levels due to increasing road traffic may occasionally interfere with some indoor and/or outdoor activities of the dwelling occupants as the sound levels may at times exceed the sound level limits of the municipal and provincial noise criteria. The development includes a number of measures to help reduce noise impacts, listed below. To ensure that provincial and municipal sound level limits are not exceeded and/or to keep sound levels as low as possible it is important to maintain the sound attenuation features provided. Wording for proposed dwellings (Unit 1) requiring an acoustic barrier is given below. Type B: This development includes an acoustic barrier to help reduce the sound levels within the rear yard of this and other nearby units. The Transferee, for himself, his heirs, executors, administrators, successors and assigns acknowledge being additionally advised that the installed acoustic barrier is on private property and must be maintained and kept in good repair by the property owner. Any maintenance, repair or replacement is the responsibility of the property owner and shall be the same material or to the same standards, having the same colour, appearance and function of the original. Wording for proposed dwellings (Units 1 – 2) requiring central air conditioning systems is given below. Type C: This dwelling unit has been supplied with a central air conditioning system which will allow windows and exterior doors to remain closed, thereby ensuring that the indoor sound levels are within the municipal and provincial sound level limits. The building components of the dwelling unit (walls, windows, and exterior doors) have been designed to provide acoustic insulation so that, when windows and exterior doors are closed, the indoor sound levels are within the municipal and provincial sound level limits. The details of this building component design are available by contacting the builder of this unit.
Noise Feasibility Study, Proposed Residential Development Page 10 77 Victoria Road, Guelph, Ontario May 7, 2021 Wording for proposed buildings (Units 3 – 18) requiring forced air ventilation systems is given below. Type D: This dwelling unit has been designed with the provision for adding central air conditioning at the occupant’s discretion. Installation of central air conditioning by the occupant will allow windows and exterior doors to remain closed, thereby ensuring that the indoor sound levels are within the municipality and provincial sound level limits. The building components of the dwelling unit (walls, windows, and exterior doors) have been designed to provide acoustic insulation so that, when windows and exterior doors are closed, the indoor sound levels are within the municipal and provincial sound level limits. The details of this building component design are available by contacting the builder of this unit. Wording for proposed buildings (Units 1 – 18) in close proximity to existing institutional facilities is given below. Type E: The Transferee, for himself, his heirs, executors, administrators, successors, and assigns acknowledge being additionally advised that due to the proximity of the adjacent library, sound levels from the library may at times be audible. 4 Stationary Noise Assessment 4.1 Criteria Governing Stationary (Industrial) Noise Sources In Ontario, the guidelines of the Ontario Ministry of the Environment, Conservation and Parks (MECP) form the basis of environmental noise assessment. MECP publication NPC-300, “Environmental Noise Guideline Stationary and Transportation Sources – Approval and Planning”, release date October 21, 2013 provides criteria for assessing the noise impact of the rooftop equipment associated with the existing school building. The term Stationary Source is used to describe all noise sources at the site including mechanical equipment, conveyances, such as trucks when they are moving within the site boundaries. The MECP guidelines assess the noise impact of fluctuating sounds on an hourly energy equivalent (average) sound level basis, rather than on short-duration maximum sound levels. Hourly equivalent sound levels are denoted as the LEQ-1hr. The MECP guidelines stipulate that the sound level impact during a “predicable worst case hour” be considered. This is defined to be an hour when a typically busy “planned and predictable mode of operation” occurs at the subject facility coincident with a period of minimal background sound.
Noise Feasibility Study, Proposed Residential Development Page 11
77 Victoria Road, Guelph, Ontario May 7, 2021
The decision to include the sound from trucks in an assessment under MECP noise guidelines
depends on the volume of trucking, and the nature of the facility. Occasional deliveries to retail
stores and convenience stores are exempt, for example, but heavy trucking at a warehouse or busy
shipping/receiving docks at an industry must generally be assessed. The likely activities at the
existing school may include the occasional movement of vehicles on the property to drop off and
pick up children, the infrequent deliveries of goods and garbage collection. These are not considered
to be significant noise sources in the MECP guidelines and are exempt from assessment. There are
no significant noise sources associated with the existing institutional buildings beyond the rooftop
mechanical equipment (i.e. deliveries, if any, would be sporadic, light and during daytime hours
only). Noise source locations are shown in Figure 3.
The criteria is based on the background sound level at sensitive points of reception (which are
typically residences) in the quietest hour that the source can be in operation. Background sound
includes sound from road traffic and natural sounds, but excludes the sources under assessment. For
relatively quiet areas where background sound may fall to low levels during some hours, NPC-300
stipulates various minimum limits. The exclusionary sound level limit for a stationary noise source in
a Class 2 area as stipulated by NPC-300 is shown in the table below.

Source sound levels for typical rooftop mechanical units and assumed operational information
(outlined below) were used as input to a predictive computer model (Cadna-A version 2021 MR2 (32
bit) : build 183.5110), in order to estimate the sound levels from the existing institutional building at
the proposed development. The computer model is based on the methods from ISO Standard 9613-
2.2, “Acoustic – Attenuation of Sound During Propagation Outdoors”, which accounts for reduction
in sound level with distance due to geometrical spreading, air absorption, ground attenuation and
acoustical shielding by intervening structures. Assumptions regarding the operating duty cycles ofNoise Feasibility Study, Proposed Residential Development Page 12

the equipment (100% during the daytime and evening, and 50% during the night-time) were included
based on our experience with other projects.
4.2 Assessment of Noise Emissions from Existing Rooftop Mechanical
Equipment at Adjacent Sensitive Receptors
Sound power levels from the existing rooftop mechanical equipment at the school building to the
south of the subject site were estimated based on an aerial photo and manufacturer’s data for the
mechanical equipment recorded on the site visit.
The source levels associated with the equipment are listed in Table V below in terms of sound power
level.

77 Victoria Road, Guelph, Ontario May 7, 2021
It is concluded that sounds from the existing rooftop mechanical equipment associated with the
adjacent institutional building are anticipated to comply with the MECP guidelines at the proposed
sensitive receptors and physical mitigation is not required.
5 Summary and Recommendations
The following list and Table VII summarize the recommendations made in this report. The reader is
referred to the previous sections of the report where these recommendations are discussed in more
detail.
1. The proposed dwelling units with flanking exposure to Victoria Road will require central air
conditioning systems. The remaining dwelling units should be equipped with forced air
ventilation systems with ductwork sized for the future installation of central air conditioning or
an alternative means of ventilation to open windows. The location, installation and sound ratings
of the air conditioning devices should comply with NPC-300, as applicable.
2. Upgraded glazing constructions are required for the dwelling units flanking onto Victoria Road,
as indicated in Section 3.3.3. When detailed floor plans and elevation drawings are available for
this dwelling unit, the glazing requirements should be refined based on actual window to floor
area ratios.
3. An acoustic barrier 2.0 m in height is required at the rear yard of Unit 1. When grading plans are
available, acoustic barrier heights should be refined as required.
4. Warning clauses, as included in the City of Guelph Noise Control Guidelines, should be included
in the property and tenancy agreements and offers of purchase or sale to inform future
owners/occupants of the noise issues and the presence of the roadways, as indicated in
Section 3.4 and as provided in Appendix C.Noise Feasibility Study, Proposed Residential Development Page 14

5.1 Implementation
To ensure that the sound control recommendations outlined above are properly implemented in the
site design, it is recommended that:
1) When architectural plans and grading plans are available, an acoustical consultant should
review the plans to determine appropriate window and wall constructions and refine acoustic
barrier requirements.
2) Prior to the issuance of occupancy permits for this development, the Municipality’s building
inspector or a Professional Engineer qualified to provide acoustical engineering services in
the Province of Ontario to certify that the noise control measures for the buildings have been
properly incorporated, installed and constructed.Subject Site Figure 1: Key Plan
