1 Introduction and Summary
HGC Engineering was retained by 2591451 Ontario Inc. to conduct a noise feasibility study for a
proposed residential development to be located on the west side of Essa Road, north of Athabasca
Road specifically at 829 Essa Road, in the City of Barrie, Ontario. The proposed development
consists of one street townhouse block for a total of ten units. The study is required by the
municipality as part of their planning and approvals process.
Road traffic for Essa Road was obtained from City of Barrie personnel. This data was used to predict
future traffic sound levels at the proposed dwellings and in the rear yards. The predicted sound levels
were evaluated in accordance with the Ministry of the Environment, Conservation and Parks’
(MECP) noise guidelines.
Predicted sound levels exceed MECP guideline limits at the dwelling units closest to Essa Road. If
the area on the ground floor is considered an outdoor amenity area, an acoustic barrier will be
required for the rear yard of the dwelling unit with flanking exposure to Essa Road. Any rooftop
terraces should include a minimum 1.07 m high solid parapet. Forced air ventilation systems with
ductwork sized for the future installation of central air conditioning by the occupant will be required
for the first four dwelling units closest to Essa Road. Any exterior wall and double-glazed window
construction meeting the minimum requirements of the Ontario Building Code (OBC) will provide
sufficient sound insulation for all proposed dwelling units. The MECP guidelines require that
warning clauses be used to inform future residents of the traffic noise impacts, proximity to existing
institutional and commercial uses, and to address sound level excesses.

2 Site Description and Noise Sources
Figure 1 is a key plan showing the location of the proposed development. The site is located on the
west side of Essa Road and north of Athabaska Road, specifically at 829 Essa Road in the City of
Barrie, Ontario. Figure 2 shows the proposed site plan dated October 29, 2018. The proposed
development will consist of one block of 3-storey townhouses for a total of ten units.
The primary source of sound is vehicular traffic on Essa Road. There is an existing 1.5-storey
dwelling unit occupying the site which will be demolished to make way for the proposed
development. There are existing residences to the north, south and west. Timothy Christian School is
located to the northeast of the subject site. There is a container storage provider (“Secure Store”) east
of the development. Noise from the facility was not heard at the time of the site visit, nonetheless, a
warning clause is recommended to inform future occupants of the development of the proximity to
existing commercial uses and that sounds may be audible, as included in Section 5.4. There are no
other sources of stationary noise within 500 m of the subject site.
3 Sound Level Criteria
Guidelines for acceptable levels of road traffic noise impacting residential developments are outlined
in the MECP publication NPC-300 “Environmental Noise Guideline Stationary and Transportation
Sources – Approval and Planning”, Part C release date October 21, 2013 and are listed in Table 1
below. The values in Table 1 are energy equivalent (average) sound levels [LEQ] in units of
A-weighted decibels [dBA].
Noise Feasibility Study, Proposed Residential Development Page 3 829 Essa Road, Barrie, Ontario August 13, 2019
Table 1: Road Traffic Sound Level Criteria
Area Daytime LEQ (16 hour)
Road Night-time LEQ (8 hour)
Road
Outdoor Living Area 55 dBA --
Inside Living/Dining Rooms 45 dBA 45 dBA
Inside Bedrooms 45 dBA 40 dBA
Daytime refers to the period between 07:00 and 23:00. Nighttime refers to the time period between
23:00 and 07:00. The term Outdoor Living Area (OLA) is used in reference to an outdoor patio,
backyard, terrace, or other area where passive recreation is expected to occur.
The MECP guidelines allow the sound levels in an OLA be exceeded by up to 5 dBA (i.e. up to
60 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 below 60 dBA and as close to 55 dBA as technically, economically and
administratively feasible.
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 are
greater than 60 dBA and where daytime sound levels outside bedroom or living/dining room
windows are 65 dBA or greater. Forced-air ventilation with ducts sized to accommodate the future
installation of central 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. The use of warning clauses to notify future residents of possible
excesses is also required.

4 Traffic Noise Assessment
4.1 Road Traffic Data
Road traffic data for Essa Road was obtained from City of Barrie personnel. Data was provided in
the form of current Annual Average Daily Traffic (AADT) volumes, and are provided in
Appendix A. The traffic volumes were grown to the year 2029 using a growth rate of 2.5% per year.
A commercial vehicle percentage of 3% was obtained and split into 1.2% medium trucks and 1.8%
heavy trucks. A day/night split of 90%/10% and a speed limit of 60 km/h was used in the analysis.
Table 2 summarizes the road traffic data used in the analysis.

4.2 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. Sample
STAMSON output is included in Appendix B.
Predictions of the traffic sound levels were made at various dwellings in the proposed development.
The results of these predictions are summarized in Table 3. The acoustic requirements may be
subject to modifications if the site plan is changed significantly.
Sound levels were predicted at the plane of the windows of the proposed dwelling units during the
daytime and nighttime to investigate ventilation and building façade construction requirements.
Sound levels were also predicted in the potential rooftop terraces of the townhouse units to
investigate the need for acoustic barriers.

5 Discussion and Recommendations
The predictions indicate that the future traffic sound levels during the daytime and nighttime at the
proposed dwellings closest to Essa Road will exceed MECP guidelines. The following discussion
outlines recommendations for ventilation requirements, building façade constructions, and warning
clauses to achieve the noise criteria stated in Table 1.
5.1 Outdoor Living Areas
The proposed townhouse units may have rooftop terraces greater than 4 metres in depth. The
predicted daytime sound levels in the rooftop terraces of all the townhouse units will be less than
55 dBA, assuming a standard 1.07 m high solid parapet around the perimeter of the area. Further
physical mitigation will not be required.
If the area at ground level is an outdoor living area, the predicted sound level will be 61 dBA, 6 dBA
in excess of the MECP’s limit of 55 dBA. Physical mitigation in the form of an acoustic barrier will
be required. An acoustic barrier 2.0 m in height will reduce sound levels in the rear yard to less than
55 dBA.
When grading information is available, the acoustic barrier heights should be refined. An acoustic
barrier may be a combination of an acoustic wall and an earth berm. 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. The heights and extents
Noise Feasibility Study, Proposed Residential Development Page 6 829 Essa Road, Barrie, Ontario August 13, 2019 of the barriers should be chosen to reduce the sound levels in the OLA’s to below 60 dBA and as
close to 55 dBA as is technically, administratively and economically feasible, subject to the approval
of the municipality respecting any applicable fence height by-laws. A sample acoustic fence
specification is provided in Appendix C.
5.2 Indoor Living Areas and Ventilation Requirements
Provision for the Future Installation of Air Conditioning
The predicted sound levels at the façades of the proposed dwelling units closest to Essa
Road (prediction location [A]) will be between 56 and 65 dBA during the daytime hours and
between 51 and 60 dBA during the nighttime hours. These dwelling units require the provision for
the future installation of central air conditioning systems. This requirement is typically satisfied
through the installation of forced air ventilation systems with ductwork sized for the future
installation of central air conditioning by the occupant.
Figure 3 shows the ventilation requirements for the development. Window or through-the-wall air
conditioning units are not recommended for any residential unit 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.
5.3 Building Façade Constructions
The proposed dwelling units will have daytime and nighttime sound levels at the top storey façade
that are less than 65 dBA and 60 dBA, respectively. Any exterior wall and double glazed window
construction meeting the minimum requirements of the Ontario Building Code (OBC) will provide
adequate sound insulation for the dwelling units. Any insulated metal exterior door meeting OBC
requirements will be sufficient to provide noise insulation.
Noise Feasibility Study, Proposed Residential Development Page 7 829 Essa Road, Barrie, Ontario August 13, 2019 5.4 Warning Clauses
The MECP guidelines recommend that warning clauses be included in the property and tenancy
agreements for all units/lots with anticipated traffic sound level excesses. Examples are provided
below.
Suggested wording for future dwellings with sound level excesses is given below:
Type A:
Purchasers and tenants are advised that sound levels due to increasing road traffic may occasionally interfere with some activities of the dwelling occupants as the sound levels exceed the Municipality’s and the Ministry of the Environment, Conservation and Parks’ noise criteria.
If the area on the ground floor is considered and outdoor amenity area, suggested wording for future
dwelling units with daytime OLA sound levels exceeding the MECP criteria by 6 dB or more, for
which physical mitigation has been provided is given below.
Type A:
Purchasers/tenants are advised that despite the inclusion of noise control features in the development and within the building units, sound levels due to increasing road traffic may occasionally interfere with some activities of the dwelling occupants as the sound levels exceed the Municipality’s and the Ministry of the Environment, Conservation and Parks’ noise criteria. The acoustical barrier as installed shall be maintained, repaired or replaced by the owner. Any maintenance, repair or replacement shall be with the same material, to the same standards and having the same colour and appearance of the original.
A suggested wording for future dwellings requiring forced air ventilation systems is given below.
Type B:
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 in low and medium density developments will allow windows and exterior doors to remain closed, thereby ensuring that the indoor sound levels are within the sound level limits of the Municipality and the Ministry of the Environment, Conservation and Parks.
Noise Feasibility Study, Proposed Residential Development Page 8 829 Essa Road, Barrie, Ontario August 13, 2019 Suitable wording for dwellings near existing institutional and commercial facilities.
Type C:
Purchasers/tenants are advised that due to the proximity of existing institutional and commercial uses, sound levels from these facilities may at times be audible.
These sample clauses are provided by the MECP as examples and can be modified by the
Municipality as required.
6 Summary of Recommendations
In summary, HGC Engineering has reviewed the site plan and performed calculations to determine
the potential road traffic noise impact on the residential properties with respect to MECP guidelines.
The following are the recommendations.
1. A 2.0 m high acoustic barrier is required for the rear yard of the end unit adjacent to Essa Road.
When grading information is available, the acoustic barrier height should be refined. A solid
1.07 m high parapet is required around the perimeter of any rooftop amenity areas.
2. Forced air ventilation systems with ductwork sized for the future installation of central air
conditioning will be required for the proposed dwelling units closest to Essa Road. The location,
installation and sound ratings of the air conditioning devices should comply with NPC-300, as
applicable.
3. Any building construction meeting the minimum requirements of the Ontario Building Code will
provide sufficient acoustical insulation for the proposed dwelling units.
4. Warning clauses should be used to inform future residents of the traffic noise excesses and the
proximity to nearby commercial and institutional uses.

When grading information is available, acoustic barrier heights should be refined. + A 1.07 m high solid parapet is required for any rooftop amenity areas.
6.1 Implementation
To ensure that the noise recommendations outlined above are fully implemented, it is recommended
that:
1. If the area on the ground floor is considered an outdoor amenity area, an acoustic barrier will
be required for the rear yard of the dwelling unit with flanking exposure to Essa Road. When
grading plans are available, acoustic barrier heights should be refined.
2. Prior to the issuance of building permits for this development, the Municipality’s building
inspector or a Professional Engineer qualified to perform acoustical engineering services in
the Province of Ontario should certify that the noise control measures have been properly
incorporated.
3. Prior to assumption, the Municipality’s building inspector or a Professional Engineer
qualified to perform acoustical engineering services in the Province of Ontario should certify
that the noise control measures have been properly installed and constructed.
