Noise Feasibility Study, Proposed Residential Development Page 1 2480 Old Bronte Road, Oakville, Ontario June 15, 2013 1 Introduction and Summary HGC Engineering was retained by New Horizon Development Group (Bronte) Inc. to conduct a noise feasibility study for a proposed mid-rise residential development (2480 Old Bronte Road) in the Town of Oakville, Ontario. The surrounding area includes existing commercial land uses to the north and existing residences to the west, south and east. A noise study is required by the municipality as part of the planning and approvals process, specifically for a Zoning By-Law Amendment. Road traffic information for Dundas Street, Bronte Road and Old Bronte Road were obtained from the Region of Halton and the Town of Oakville. The data was used to predict future traffic sound levels at the locations of the proposed residential dwelling facades. The predicted sound levels were compared to the guidelines of the Ministry of Environment (MOE), Region and Town. The current analysis is based on a review of the pertinent MOE guidelines, a review of the latest site plan concept prepared by Karp Namisniak Yamamoto provided to HGC Engineering on June 3, 2013, site visits, and review of an aerial photo of the area. Site visits were conducted during March 2013 to identify significant transportation and commercial noise sources in the vicinity of the proposed development. Reasonable assumptions have been used in the analysis to predict sound levels associated with nearby commercial operations on the proposed development. The predicted sound levels were compared to the guidelines of the Ministry of Environment (MOE) Guidelines for Noise Control in Land Use Planning. The results of this study indicate that with suitable noise control measures integrated into the design of building, it is feasible to achieve the indoor MOE guideline sound levels from the road traffic sources. The recommended noise control measures include appropriate wall and window glazing assemblies, and air-conditioning of suites so that windows can be kept closed. A number of warning clauses will need to be included in the property and tenancy agreements to warn occupants of potentially audible transportation noise levels and the presence of nearby commercial plaza.

Noise Feasibility Study, Proposed Residential Development Page 2 2480 Old Bronte Road, Oakville, Ontario June 15, 2013 2 Site Description and Noise Sources Figure 1 is a key plan of the site. Figure 2 is the latest site plan concept prepared by Karp Namisniak Yamamoto provided to HGC Engineering on June 3, 2013. Prediction locations [A] to [K] are indicated on Figure 2 for reference purposes. The proposed residential development is to consist of two 8-storey residential buildings, underground parking area and ground level parking areas. One heritage house is to be relocated to the southeast corner of the site. Appendix A includes supporting drawings and building elevations. Site visits were made by HGC Engineering personnel in the month of March 2013 to make observations of the acoustical environment, inspect and perform sound level measurements of neighbouring commercial operations and background sound levels due to road traffic. There is one commercial plaza to the north which includes the following businesses: Fasada (windows, doors, shutter, blinds, interiors), Westoak Animal Hospital, Ambiance Spa and Palermo Pub. There are existing residences to the west, east and south of the subject site. 3 Assessment of Road Traffic Noise on the Proposed Residential Buildings 3.1 Road Traffic Noise Criteria Guidelines for acceptable levels of road traffic noise impacting indoor spaces are given in the MOE publication LU-131 "Noise Assessment Criteria in Land Use Planning, 1997", its Annex and its accompanying document Requirements, Procedures and Implementation, 1997. These criteria are listed in Table I below. The values in Table I are energy equivalent average sound levels [L EQ ] in units of A-weighted decibels [dba].

Noise Feasibility Study, Proposed Residential Development Page 3 2480 Old Bronte Road, Oakville, Ontario June 15, 2013 Area Table I: MOE Road Traffic Noise Criteria (dba) Daytime L EQ (16 hour) Road Nighttime L EQ (8 hour) Road Outside Bedroom Windows -- 50 dba Outdoor Living Area 55 dba -- Inside Living/Dining Rooms 45 dba -- Inside Bedrooms -- 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 used in reference to an outdoor patio, a backyard, a terrace or other area where passive recreation is expected to occur. Balconies that are less than 4 m in depth are not considered to be outdoor living areas under MOE guidelines. The MOE guidelines allow the daytime sound levels in an Outdoor Living Area (OLA) to be exceeded by up to 5 dba, without mitigation, provided that a clause warning future occupants of the potential noise concern is included to advise future owners or tenants through all offers of purchase and sale, and rental agreements. Where OLA sound levels exceed 60 dba, physical mitigation is recommended to reduce the OLA sound level to 60 dba or less. MOE guidelines require central air conditioning or other ventilation system installed prior to occupancy as an alternative means of ventilation to open windows for dwellings where nighttime sound levels outside bedroom windows exceed 60 dba or daytime sound levels exceed 65 dba outside living room windows. Provision for air conditioning is required when nighttime sound levels at bedroom windows are in the range of 51 to 60 dba. Sound attenuating building constructions are required when nighttime sound levels exceed 60 dba at the plane of the bedroom window due to road noise. Warning clauses are required to notify future residents of possible sound level excesses are also required when nighttime sound levels exceed 50 dba at the plane of the bedroom window due to road traffic.

Noise Feasibility Study, Proposed Residential Development Page 4 2480 Old Bronte Road, Oakville, Ontario June 15, 2013 3.2 Traffic Noise Assessment 3.2.1 Road Traffic Data The Town of Oakville recently adopted Old Bronte Road/Khalsa Gate from the Region of Halton and has not collected any traffic volume data. Data for Old Bronte Road/Khalsa Gate was obtained from HGC Engineering project files and has been used in the absence of recent data from the Town of Oakville. A speed limit of 60 km/h was used for Khalsa Gate. An estimated commercial vehicle percentage of 2% medium trucks was also used in the analysis, along with a day-night split of 90%/10%. Ultimate road traffic information for the Dundas Street and Bronte Road was obtained from the Region of Halton, and is provided in Appendix B. A speed limit of 60 km/h was used for both roadways. A commercial vehicle percentage of 13% was used for Dundas Street, split into 8% medium trucks and 5% heavy trucks, along with a day-night split of 90%/10%. A commercial vehicle percentage of 8% was used for Bronte Road, split into 5% medium trucks and 3% heavy trucks, along with a day-night split of 90%/10%. Table II below summarizes the road traffic volumes used in the current analysis.

Noise Feasibility Study, Proposed Residential Development Page 5 2480 Old Bronte Road, Oakville, Ontario June 15, 2013 3.2.2 Road Traffic Noise Predictions Prediction locations were chosen around the subject site to obtain a good representation of the future sound levels at the dwelling facades. The predictions were made using STAMSON version 5.04, a computer algorithm developed by the MOE. Sample STAMSON output is included in Appendix C. The results of the predictions are presented in Table III. Sound levels were predicted at the most impacted facades during the daytime and nighttime hours to investigate ventilation requirements. The building envelope setback indicated on the latest site plan concept was used in the analysis.

Noise Feasibility Study, Proposed Residential Development Page 6 2480 Old Bronte Road, Oakville, Ontario June 15, 2013 3.3 Discussion and Recommendations The sound level predictions indicate that road traffic sound levels exceed MOE criteria during the daytime and nighttime at the facades with exposure to the roadways. Recommendations are provided below. 3.3.1 Outdoor Living Areas The dwelling units in the 8-storey buildings will have balconies that are less than 4 m in depth. Such balconies are exempt from the definition of OLA under MOE guidelines. They are therefore, exempt from traffic noise assessment and physical mitigation will not be required. There are no other outdoor amenity areas identified on the site plan concept. 3.3.2 Ventilation Requirements The predicted sound levels at all the facades are high enough that the residential buildings should be equipped with central air conditioning systems to allow windows to remain closed. It is anticipated that central air conditioning systems will be provided in all suites. The outdoor rooftop mechanical equipment associated with the central air conditioning systems for the residential buildings should comply with the criteria of MOE publication NPC-205, Sound Level Limits for Stationary Sources in Class 1 & 2 Areas (Urban). 3.3.3 Building Facade Construction Predicted sound levels at the building facades were used to determine preliminary sound insulation requirements for the building envelope. Exterior Wall Construction The construction of the exterior walls of the buildings has not yet been finalized, but may include masonry components or spandrel glass and/or metal panels within an aluminum window system. The ground floors will include stone, the second floor will include partial stone materials and the rest of the floors will include EIFS material. In this analysis, it has been assumed that sound transmitted through elements other than the glazing elements is negligible in comparison. For example, if the exterior walls include spandrel glass or metal panels within an aluminum window system, sufficient

Noise Feasibility Study, Proposed Residential Development Page 7 2480 Old Bronte Road, Oakville, Ontario June 15, 2013 sound insulation can typically be achieved by using a drywall assembly (2 layers) on separate framing behind the spandrel panels. Exterior Doors There may be glazed exterior doors (sliding or swing) for entry onto the balconies from living/dining rooms and some bedrooms. The glazing areas of the doors should be counted as part of the total window glazing area. All exterior doors should include good weather seals to reduce air infiltration to the minimum achievable levels. Acoustical Requirements for Glazing Assuming a maximum window to floor area of 50% (30% fixed and 20% operable) for the living/dining rooms and 50% for the bedrooms (30% fixed and 20% operable), the minimum acoustical requirement for the basic window glazing, including glass in fixed sections, sliding doors, and operable windows, is shown in Table IV.

Operable sections include sliding glass doors and operable windows, and provided that they include a good seal, will not significantly affect overall performance. Operable windows and sliding glass doors must be wellfitted and weather-stripped. Sample window assemblies which may achieve the STC requirements are summarized in Table V below. Note that acoustic performance varies with manufacturers construction details, and these are

OBC indicates any glazing construction meeting the minimum requirements of the Ontario Building Code. When the detailed floor plans and building elevations are available for both residential buildings, an acoustical consultant should refine the glazing constructions based on actual window to floor areas. 3.3.4 Warning Clauses The MOE noise guidelines recommend that warning clauses be included in the property and tenancy agreements for all dwellings, to inform prospective occupants of the potential traffic sound level excesses. The following sample warning clauses can be modified by the Municipality, as required. 8-storey residential buildings Type I: Purchasers are advised that despite the inclusion of noise control features in this development area and within the dwelling units, sound from increasing road traffic may continue to be of concern and may occasionally interfere with some activities of the dwelling occupants, as the outdoor traffic sound levels may exceed the noise criteria of the Municipality and the Ministry of Environment. This dwelling unit has been supplied with a central air conditioning system which allows windows and exterior doors to remain closed, thereby ensuring that the indoor sound levels are within the noise criteria of the Municipality and the Ministry of the Environment.

Noise Feasibility Study, Proposed Residential Development Page 10 2480 Old Bronte Road, Oakville, Ontario June 15, 2013 Purchasers are advised of the proximity of adjacent commercial plaza, the sound from which may at times be audible. These sample clauses are provided by the MOE as an example and can be modified by the Municipality as required. The reader is referred to Section 5 which contains a summary of the noise control recommendations for road traffic as well as industrial/commercial noise. 4 Assessment of Existing Stationary Sources of Sound There is one commercial building abutting the north property line of the subject site. HGC Engineering visited the subject site to observe these operations and identify potentially significant sources of sound during the month of March 2013. Access to the rooftop was not obtained. From site observations and from aerial photos of the adjacent commercial building, the noise sources identified to be potentially significant with respect to the subject site were associated rooftop mechanical equipment. Figure 1 indicates the nearby commercial building. The commercial plaza to the north which includes the following businesses: Fasada (windows, doors, shutter, blinds, interiors), Westoak Animal Hospital, Ambiance Spa and Palermo Pub. The businesses in the area of the subject site can be classified as commercial or office use. Typical hours of operation are 8 am to 6 pm. There is a pub which may be open until 11 pm. For the purposes of this analysis, the hours of operation were assumed to be 7 am to 11 pm. 4.1 Criteria for Acceptable Sound Levels Under MOE guidelines, the acoustical environment in this area is classified as urban or Class 1, as background sound levels are set by significant volumes of road traffic on surrounding roadways during daytime and night-time hours. Traffic on Dundas Street and Bronte Road audibly dominates the existing sound levels on the site. Stationary sources of noise are defined as all sources that emit noise within a commercial or

Noise Feasibility Study, Proposed Residential Development Page 11 2480 Old Bronte Road, Oakville, Ontario June 15, 2013 industrial facility boundary. The commercial plaza to the north of the proposed residential development can be classified as stationary sources of sound. The Ministry of the Environment (MOE) provides guidelines for the assessment of stationary noise sources. LU-131, Noise Assessment Criteria in Land Use Planning, and its accompanying Annex, is intended for use in the planning of noise sensitive land uses adjacent to industrial and commercial facilities. The facade of a residence (i.e., the plane of a window to a noise sensitive interior space such as a bedroom or living/dining room), or any associated usable outdoor area are considered to be sensitive points of reception. For an urban area such as this, LU-131 stipulates that the limit for non-impulsive sound (sounds that do not have a marked impulsive character) is the greater of the exclusionary minimum sound level limit, or the hourly average level of road traffic (L eq ) in any hour that the source under consideration may operate (i.e. L eq1hr ). The exclusionary sound level limit for an urban Class 1 area is taken to be 50 dba during daytime hours (07:00 to 23:00), and 45 dba during nighttime hours (23:00 to 07:00). If the background sound levels due to road traffic exceed the exclusionary limits, then the background sound level becomes the criterion. The sound level limits in LU-131 are quite similar to those in NPC-205 which is used for industrial approvals under the Environmental Protection Act, with the exception that for land use planning purposes, the MOE guidelines allow for minor excesses, considering that control measures are not always fully feasible or effective. Occasional deliveries to restaurants and convenience stores are exempt from noise assessment, but heavy truck movements at a warehouse or busy shipping/receiving docks at an industry must generally be assessed. The building to the north may have deliveries with small cube vans, since there is no space for large tractor trailers. Trucking activities have not been included in this assessment since these activities were not observed during the site visit. Compliance with MOE criteria generally results in acceptable levels of sound at residential receptors although there may be residual audibility during periods of low background sound.

Noise Feasibility Study, Proposed Residential Development Page 12 2480 Old Bronte Road, Oakville, Ontario June 15, 2013 4.2 Minimum Hour Background Sound Levels at the Residential Receptors Typical ambient sound levels can be determined through prediction of road traffic volumes in areas where traffic sound is dominant. Where it can be demonstrated that the hourly ambient sound levels are greater than the exclusionary minimum limits listed above, the criterion becomes the lowest predicted one-hour L EQ sound level during each respective period. At locations where the ambient sound levels are low, the exclusionary minimum criteria of 50/45 apply. Because background sound in the vicinity of the subject development is dominated by road traffic it is appropriate to predict hourly background sound from road traffic volumes in order to determine applicable limits for impact of stationary noise sources. Hourly daytime traffic data was available for Dundas Street and Bronte Road from the Region of Halton and is provided in Appendix A. The minimum traffic volume during the daytime hours occurs at 10 11 pm. The minimum traffic volume during the nighttime hours occurs at 3 4 am. A commercial vehicle percentage of 8% was used for Bronte Road, split into 5% medium trucks and 3% heavy trucks along with a posted speed limit of 60 kph. A commercial vehicle percentage of 13% was used for Dundas Street, split into 8% medium trucks and 5% heavy trucks along with a posted speed limit of 80 kph. The traffic volumes were then used to predict minimum traffic sound levels at the closest residential receptors (R1 and R2, as shown in Figure 3) during the quietest day/nighttime hours. The worst case locations are the third and fourth floors of the residential buildings where the commercial plaza rooftop units are most exposed.

Noise Feasibility Study, Proposed Residential Development Page 13 2480 Old Bronte Road, Oakville, Ontario June 15, 2013 Table VI: Predicted Minimum Hourly Sound Levels and Noise Level Criteria at Residential Receptors [dba] Receptor Daytime (07:00 23:00) Night-time (23:00 07:00) R1, north façade, of 8-storey building facing Dundas Street 56 47 R2, north façade of 8-storey building facing Dundas Street with exposure to Bronte Road 59 49 Since the sound levels predicted are higher than the minimum exclusionary limits at the closest receptors, the predicted sound levels in Table VI were used to set both the daytime and nighttime criteria. It is noted that background sound levels from road traffic will be even higher in the future, due to future growth of road traffic, as the area develops. In each case, the limits apply at any point on the residential property, and outside the residential windows. 4.3 Noise Assessment Predictive noise modelling was used to assess the potential sound impact of rooftop equipment at the closest residential receptors. The noise prediction model was based on sound emission levels for rooftop equipment, assumed operational profiles (during the daytime), and established engineering methods for the prediction of outdoor sound propagation. These methods include the effects of distance, air absorption, and acoustical screening by barrier obstacles. Sound emission data for the rooftop equipment was obtained for similar commercial plaza from HGC Engineering project files and were used in the analysis. In accordance with establishing the predictable worst-case conditions, the rooftop HVAC equipment was assumed to operate at 100% capacity during daytime and evening hours, and 50% during night-time hours. The sound levels were used as input to a predictive computer model. The software used for this purpose (Cadna-A version 4.2.141 is a computer implementation of ISO Standard 9613-2.2 Acoustics - Attenuation of Sound During Propagation Outdoors. The ISO method accounts for reduction in sound level with distance due to geometrical spreading, air absorption, ground

Noise Feasibility Study, Proposed Residential Development Page 14 2480 Old Bronte Road, Oakville, Ontario June 15, 2013 attenuation and acoustical shielding by intervening structures such as barriers. The assumed sound power levels are listed in the table below. Table VII - Sound Power Level Specifications for Equipment [db re 10-12 W] Source Octave Band Centre Frequency [Hz] 63 125 250 500 1k 2k 4k 8k HVAC unit, 5 Ton -- 72 70 71 68 63 57 48 Carnes roof exhaust 90 86 80 76 73 72 73 61 condenser/compressor unit 94 93 88 86 86 82 78 70 The rooftop units were assumed to be located as per site observations and aerial photography. Four 5 Ton rooftop units, one 3 Ton rooftop unit, 1 exhaust fan and one condenser/compressor unit was assumed on the commercial plaza roof. Sound data for the HVAC units were obtained from HGC Engineering project files and are provided in Table VII. The location of the rooftop units are shown as crosses in the Figures3 5. Since the commercial plaza operates during the daytime and evening hours, a typical worst-case (busiest hour) scenario during the day was considered to be as follows: Assumed daytime worst-case scenario: All equipment operating continuously at full capacity; Assumed night-time worst-case scenario: All A/C equipment operating on a 50% duty cycle; The operating profiles outlined above were assumed in determining the one-hour equivalent sound level, L EQ, for a predictable worst case daytime and nighttime hour at the facades of the proposed residential buildings. Garbage collection and any shipping and receiving taking place will generally occur during the daytime hours. Commercial activities such as the occasional movement of customer vehicles on the

Noise Feasibility Study, Proposed Residential Development Page 15 2480 Old Bronte Road, Oakville, Ontario June 15, 2013 property, the infrequent delivery of goods to convenience stores, fast food restaurants etc. and garbage collection are not of themselves considered to be significant noise sources in the MOE guidelines. The calculations consider the acoustical effects of distance and shielding by the buildings where applicable. The unmitigated sound levels due to the rooftop mechanical equipment at the closest neighbouring residences are summarized in the following table. Sound level contours are shown in Figures 4 and 5. Table VIII: Predicted Daytime Sound Levels at Residential Receptors [dba], Without Mitigation Receptor Criteria (Day/Night) Daytime Nighttime R1, north façade, of 8-storey building facing Dundas Street 56 / 47 54 51 R2, north façade of 8-storey building facing Dundas Street with exposure to Bronte Road 59 / 49 47 44 These results indicate that sound levels under a worst case operational scenario may exceed the MOE sound level limits by a minor amount (less than 5 dba) at the closest residential building (R1) to the commercial plaza, during the nighttime hours. Recommendations are provided in the following sections. 4.4 Discussion and Recommendations With Regard to Stationary Noise Sources Physical mitigation options with respect to the commercial plaza are quite limited in this case. With regard to the subject site, the MOE does not accept mechanical ventilation as a mitigation measure for stationary noise sources since the criteria apply outside the residential windows, however, it should be noted that the proposed residential buildings will include central air conditioning so that windows can remain closed. On site mitigation is therefore generally implemented through the provision of property line noise barriers and in this case such barriers are not feasible due to the

Noise Feasibility Study, Proposed Residential Development Page 16 2480 Old Bronte Road, Oakville, Ontario June 15, 2013 height of the receptors (upper windows). Exterior corridors or glazed solaria are options which could be considered for facades and storeys closest to the rooftop equipment to remove the affected residential windows (living rooms and bedrooms) of the dwelling units as points of reception, but such features are not considered to be feasible in the context of this development and considering the minor nature of the excess. Considering a worst case operational scenario, the Municipality may consider the minor nature of any potential noise excess to be acceptable in this case. The presence of the neighbouring commercial plaza should be addressed through the implementation of warning clauses in the offers of purchase and sale and tenancy agreements for the residential units. A typical wording is Purchasers are advised of the proximity of adjacent commercial plaza, the sound from which may at times be audible. 5 Summary of Recommendations The following recommendations are provided in regard to noise mitigation. 1. The residential buildings should be equipped with central air conditioning systems that will allow the windows to remain closed. The outdoor mechanical equipment associated with the central air conditioning systems for the residential building should comply with the criteria of MOE publication NPC-205, Sound Level Limits for Stationary Sources in Class 1 & 2 Areas (Urban). 2. Any glazing construction meeting the STC ratings presented in Table IV will provide sufficient acoustical insulation for the indoor spaces. 3. A detailed noise study should be conducted for the residential buildings when detailed floor plans and building elevations are available to refine glazing constructions based on actual window to floor area ratios. 4. Warning clauses should be included in the property and tenancy agreements and offers of purchase and sale for the dwelling units in the residential buildings to inform the future

Noise Feasibility Study, Proposed Residential Development Page 17 2480 Old Bronte Road, Oakville, Ontario June 15, 2013 owners/occupants of the noise issues and the presence of the roadways and the nearby commercial plaza. The reader is referred to the previous sections of this report where these recommendations are discussed in more detail. 5.1 Implementation To ensure that the noise control recommendations outlined above are fully implemented, it is recommended that: 1. A detailed noise study should be conducted by a Professional Engineer qualified to provide acoustical engineering services in the Province of Ontario when architectural plans (floor plans and elevations) are available to determine and specify the building envelope construction for the buildings, specifically glazing constructions based on actual window to floor area ratios. 2. Prior to the issuance of building permits for this development, a Professional Engineer qualified to perform acoustical services in the Province of Ontario shall review the builder's plans to ensure that the sound control measures as recommended in this report have been incorporated in their entirety.

For Bronte Road, the newest information is as follows: Bronte Road: 2011 AADT 29,000 2031 AADT 45,000 Posted Speed Limit 60 km/h Lanes by 2031 6 Trucks 5% medium, 3% heavy For Old Bronte Road, please contact the Town of Oakville (I don t think the 77,000 is accurate, maybe 7,000 (typo?)). They are doing a review/study for the ultimate design for Old Bronte Road so they should have developed ultimate volumes hopefully. I hope this helps.
