3 Noise Feasibility Study, Mixed Use Development Page Martha Street, Burlington, Ontario September 4, INTRODUCTION AND SUMMARY HGC Engineering was retained by Adi Development Group to conduct a noise feasibility study for a proposed mixed use development to be located at the northwest corner of Lakeshore Boulevard and Martha Street, specifically at 374 Martha Street in Burlington, Ontario. The surrounding area includes residential and commercial land uses. A noise study is required by the municipality as part of the approvals process, specifically for rezoning and official plan amendment. This study is conducted in accordance with the guidelines of the Ministry of Environment (MOE). The primary noise sources which require analysis are: road traffic on Lakeshore Boulevard and its potential impact on the proposed residential building, the existing commercial and residential uses and their potential impact on the proposed residential building and any noise sources which are associated with the proposed residential building such as rooftop mechanical equipment and parking garage exhaust fans and their potential impact on the existing nearby residences. The results from the study indicate that the development is feasible from an environmental noise perspective. The road traffic sound level predictions indicate that noise control measures should be incorporated into the building envelope design such that indoor sound levels can comply with the MOE noise criteria. The recommended noise control measures include appropriate wall and window glazing assemblies, and air-conditioning of residential suites so that windows can be kept closed. Warning clauses are also recommended to inform the residents of the building of the traffic noise impacts and the presence of nearby commercial/office/retail facilities. A preliminary analysis of the sound levels associated with rooftop mechanical equipment and parking garage exhaust fans associated with the development are likely to meet the applicable limits at the existing residences to the north and east. Detailed noise studies should be conducted when mechanical equipment specifications for the rooftop units and parking garage exhaust fans are available to confirm that the sound level limits will be met. A preliminary analysis of the sound levels associated with rooftop mechanical equipment associated with the adjacent retirement home to the east was found to have the potential to exceed the applicable limits at the proposed residential building. Conceptual recommendations for mitigation

4 Noise Feasibility Study, Mixed Use Development Page Martha Street, Burlington, Ontario September 4, 2014 are provided. If B19R certification is to be sought, an acoustical consultant is required to review the mechanical and electrical drawings and details of demising constructions and mechanical/electrical equipment, when available, to help ensure that the noise impact of the development on itself are maintained within acceptable levels. 2 SITE DESCRIPTION AND NOISE SOURCES Figure 1 is a context plan of the site. Figure 2 is the site plan prepared by Raw Design dated August 28, The proposed development is to consist of one 5-storey high podium with a 28 storey residential tower above. There are 4 levels of underground parking. Commercial retail uses and parking spaces are located on the 1 st to 4 th Floor. Residential suites are located on the 5 th to 28 th floors. Preliminary elevations and floor plans are attached as Appendix A. Site visits were made by HGC Engineering personnel in July and August 2014 to make observations of the acoustical environment. The lands to the north and east are existing residential uses, including a retirement residence. To the south and west are existing commercial uses. The subject site is located in a Class 1 (urban) acoustical environment where the background sound is primarily made up of the sounds of road traffic and human activity (the urban hum). The dominant traffic noise source that will impact the proposed development is road traffic on Lakeshore Boulevard. Rooftop mechanical equipment associated with the commercial facilities and retirement residence closest to the development may potentially impact the proposed residential building. An assessment of the road traffic noise and rooftop mechanical equipment associated nearby commercial facilities at the proposed residential building was conducted. An assessment of noise from the rooftop mechanical equipment and parking garage exhaust fans associated with the proposed residential building was also conducted. Further details can be found in the following sections.

5 Noise Feasibility Study, Mixed Use Development Page Martha Street, Burlington, Ontario September 4, CRITERIA 3.1 Road Traffic Noise Criteria Guidelines for acceptable levels of road traffic noise impacting residential developments are given in the MOE publication NPC-300, Environmental Noise Guideline Stationary and Transportation Sources Approval and Planning, release date October 21, 2013, and 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]. Area Table I: MOE Road Traffic Noise Criteria (dba) Daytime L EQ (16 hour) Road Nighttime L EQ (8 hour) Road Outside Bedroom Windows 55 dba 50 dba Outdoor Living Area 55 dba -- Living/Dining Room 45 dba -- Bedroom 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 to be exceeded by up to 5 dba, without mitigation, if warning clauses are placed in the purchase and tenancy agreements to the property. Where OLA sound levels exceed 60 dba, physical mitigation is recommended 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 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

6 Noise Feasibility Study, Mixed Use Development Page Martha Street, Burlington, Ontario September 4, 2014 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 to notify future residents of possible excesses are also required when nighttime sound levels exceed 50 dba at the plane of the bedroom or living/dining room window and 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 Criteria for Stationary Sources of Sound 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. Stationary sources of noise are defined as all sources that emit noise within a commercial or industrial/institutional facility boundary. All of the commercial facilities surrounding the proposed mixed development can be classified as stationary sources of sound. The Ministry of the Environment (MOE) provides guidelines for the assessment of stationary noise sources. NPC-300 Environment Noise Guideline Stationary and Transportation sources Approval and Planning referenced with regard to traffic noise above is also 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, NPC-300 stipulates that the limit for nonimpulsive 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

7 Noise Feasibility Study, Mixed Use Development Page Martha Street, Burlington, Ontario September 4, 2014 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). Typical ambient sound levels can be determined through automatic sound level monitoring or predicted from road traffic volumes in areas where traffic sound is dominant. Where it can be demonstrated that the hourly background sound levels remain greater than the exclusionary minimum limits listed above, the criterion becomes the lowest measured/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 dba apply. 4 ASSESSMENT OF ROAD TRAFFIC NOISE ON THE PROPOSED RESIDENTIAL BUILDING 4.1 Traffic Noise Predictions Road Traffic Data Road traffic data for Lakeshore Road was obtained from the City of Burlington in the form of turning movement Annual Average Daily Traffic (AADT) and is provided in Appendix B. A commercial vehicle percentage of 3.3% split into 1.3% medium trucks and 2.1% heavy trucks was used for Lakeshore Boulevard. The posted speed limit for Lakeshore Boulevard is 60 kph. Table II summarizes the ultimate traffic volume data. Table II: Road Traffic Data Projected to 2024 Road Name Cars Medium Heavy Trucks Trucks Total Daytime Lakeshore Blvd Nighttime Total Road Traffic Noise Predictions Prediction locations (Location [A] to [F] as indicated on Figure 2 were chosen around the residential building to obtain a good representation of the future sound levels at the dwelling units. The predictions were made using STAMSON version 5.04, a computer algorithm developed by the MOE.

8 Noise Feasibility Study, Mixed Use Development Page Martha Street, Burlington, Ontario September 4, 2014 Sample STAMSON output is included in Appendix C. The results of the predictions are presented in Table III. These results are based on the latest proposed site plan prepared by Raw Design. Sound levels were predicted at the top storey of the proposed residential building during the daytime and nighttime hours to investigate ventilation requirements. South levels were also predicted on outdoor terraces on the 5 th floor and rooftop during daytime hours to determine any noise barrier requirements. The building envelope setback indicated on the site plan was used in the analysis. Prediction Location Table III: Predicted Future Traffic Sound Levels Description Daytime At Façade, L EQ (16) Nighttime At Façade, L EQ (8) [A] South Façade, 28th floor [B] East Façade, 28th floor [C] North façade, 28th floor <55 <50 [D] West façade, 28th floor [E] 5 th Floor Terrace* [F] Rooftop Amenity Area* <55 -- Note:* Includes 1.07m parapet 4.2 Discussion and Recommendations The sound level predictions indicate that road traffic sound levels are expected to exceed MOE criteria during the daytime and nighttime at the facade with exposure to Lakeshore Boulevard. Recommendations are provided below Outdoor Living Areas The dwelling units have balconies that are less than 4 m in depth. Such balconies are not considered to be outdoor living areas under MOE guidelines. They are therefore, exempt from traffic noise assessment and physical mitigation will not be required. Common outdoor amenity areas are proposed on the 5 th floor and the roof. The predicted sound levels at these terraces will be between dba with a minimum 1.07m high parapet. Sound level excesses up to 5 dba are acceptable to the MOE without requiring physical mitigation with the use of a warning clause.

9 Noise Feasibility Study, Mixed Use Development Page Martha Street, Burlington, Ontario September 4, Ventilation Requirements It is understood that all dwelling units will be provided with central air conditioning which will satisfy the MOE ventilation requirements. All rooftop mechanical equipment associated with the cooling system should comply with the criteria of MOE publication NPC Building Facade Constructions The predicted sound levels at the façade for the dwelling units directly facing Lakeshore Boulevard (all dwelling units with windows facing south) will be greater than 65 dba during the daytime hours. MOE requires that building façade constructions be specified. Calculations were performed to determine the building envelope constructions required to maintain indoor sound levels within MOE 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 anticipated typical area ratios of the facade components (walls, windows, roofs and doors) and the floor area of the adjacent room Exterior Wall Constructions In this analysis, it has been assumed that sound transmitted through elements other than the glazing elements is negligible in comparison. The exterior walls should have sufficient acoustical insulation value such that the noise transmitted through the walls is negligible in comparison with the windows. The exterior walls may include spandrel glass or metal panels within an aluminum window system. Sufficient sound insulation can typically be achieved by using a drywall assembly on separate framing behind the spandrel panels. The recommended construction of this assembly depends on the details of the exterior spandrel panels as well as the relative wall areas versus the window areas in a given room. Further input regarding the design of the exterior walls can be provided during design development, if required 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 on the doors should be counted as part of the total

10 Noise Feasibility Study, Mixed Use Development Page Martha Street, Burlington, Ontario September 4, 2014 window glazing area. All exterior doors should include good weather seals to reduce air infiltration to the minimum achievable levels Glazing For the living/dining room of each floor adjacent to Lakeshore Boulevard, a glazing construction with a Sound Transmission Class (STC) rating of 30 will provide sufficient sound insulation for all living/dining rooms as long as the window area to floor area ratios does not exceed 80% and for bedrooms as long as the window area to floor area ratios does not exceed 63% Warning Clauses The MOE guidelines recommend that warning clauses be included in the property and tenancy agreements for all dwelling units. Suitable wording for future dwellings with sound level excesses is given below. 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 on Lakeshore Boulevard may occasionally interfere with some activities of the dwelling occupants as the sound levels exceed the Ministry of the Environment s noise criteria. 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 Municipality s and the Ministry of the Environment s noise criteria. This sample clause is provided by the MOE as an example and can be modified by the Municipality as required. 4.3 Summary of Traffic Noise Control Recommendations for the Proposed Residential Uses The following recommendations are provided in regard to noise mitigation for road traffic noise for the proposed residential building. 1. Central air conditioning will be provided to all residential units which satisfy MOE ventilation requirements. The mechanical equipment should comply with the criteria of MOE publication NPC-300.

11 Noise Feasibility Study, Mixed Use Development Page Martha Street, Burlington, Ontario September 4, Upgraded glazing constructions will be required for dwellings units with windows facing south towards Lakeshore Boulevard. 3. Warning clauses should be included in the property and tenancy agreements and offers of purchase and sale to inform the future residents of the residential building of the noise issues and the presence of the roadways. The reader is referred to the previous sections of the report where these recommendations are discussed in more detail. 5 IMPACT OF THE PROPOSED DEVELOPMENT ON THE ENVIRONMENT Commercial (stationary noise) sources of sound are assessed separately from traffic sources under MOE Guidelines. It is expected that any increase in local traffic associated with the development will not be substantial enough to affect noise levels significantly. At the time of this study, the design of the proposed building was in its initial stages, and the mechanical systems had not yet been developed. A preliminary noise impact assessment of the proposed residential development at existing residences has been conducted based on information obtained from similar residential buildings. The potential sources of concern associated with this development are understood to be parking garage exhaust fans (exhaust well terminates at grade at the northeast corner of the building) and cooling units located in the rooftop mechanical penthouse. The location of the parking garage exhaust fan vent is shown on Drawing No. A201 attached in Appendix A. There are existing residences to the north and east of the site (R1 R3) and are considered to be the sensitive receptors in this assessment. R1 is 1-storey residence to the north, R2 is a 3-storey live/work building and R3 is a 5-storey retirement residence to the east. Receptor locations are shown on Figure 2. The exclusionary daytime and nighttime limits of 50 dba and 45 dba outlined in Section 3.2 apply for all receptors. An overall outdoor sound power level of 110 dba was assumed for the rooftop mechanical

12 Noise Feasibility Study, Mixed Use Development Page Martha Street, Burlington, Ontario September 4, 2014 penthouse of the residential building. The HVAC equipment was assumed to operate at 100% capacity during daytime hours and 50% during night-time hours. The parking garage exhaust fans are likely to be low pressure fans which will be connected to a carbon monoxide system and as such, the exhaust fans will only operate on an as needed basis. An overall sound power level of 80 dba was assumed for the parking garage exhaust fans. The parking garage exhaust fans are assumed to operate at 50% capacity during daytime and night-time hours. Calculations at the top storey of each receptor indicate that the predicted sound levels from the proposed development using the assumptions stated above will meet the applicable MOE limits at the residential receptors to the north and east. A Professional Engineer qualified to perform acoustical engineering services should review the design of the mechanical building systems and the equipment selections when they have been determined, to ensure that the noise levels emitted by the development to the environment are likely to meet the applicable limits. Tarion Builders Bulletin B19R requires that the internal design of condominium projects integrates suitable acoustic features to insulate the suites from noise from each other and amenities in accordance with the OBC, and limit the potential intrusions of mechanical and electrical services of the buildings on its residents. If B19R certification is to be sought, an acoustical consultant is required to review the mechanical and electrical drawings and details of demising constructions, details of any mechanical equipment associated with the ventilation systems and underground parking, when available, to help ensure that the noise impact of the development on itself are maintained within acceptable levels.

13 Noise Feasibility Study, Mixed Use Development Page Martha Street, Burlington, Ontario September 4, IMPACT OF EXISTING STATIONARY SOURCES OF SOUND ON THE PROPOSED RESIDENTIAL BUILDING There are numerous existing commercial uses surrounding the site. HGC Engineering visited the proposed site on several occasions to observe these operations and identify significant sources of sound during the month of July and August Description of the Adjacent Facilities Potential significant noise sources are observed to be rooftop HVAC units associated with the 1- storey commercial plaza to the west of the residential building and rooftop mechanical units associated with the 5-storey retirement residence located to the east of the residential building. 1-Storey Commercial Plaza The commercial plaza is located directly to the west of the development. The plaza consists of medical and law offices. Sources of sound associated with plaza are the rooftop HVAC equipment. Four rooftop HVAC units were observed. 5-Storey Retirement Residence The retirement residence is located on the east side of Martha Street. Sources of sound associated with the residence are the rooftop HVAC equipment. There are condensing units and air makeup units on the rooftop which were visible from the ground. 6.2 Noise Assessment Predictive noise modelling was used to assess the potential noise impact of existing rooftop equipment from surrounding facilities at the proposed residential building. The noise prediction model was based on sound emission levels for rooftop equipment, assumed operational profiles (during the daytime and nighttime), 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 typical rooftop equipment obtained from HGC Engineering files was used in the analysis. Locations of the rooftop equipment were obtained from aerial photography. In accordance with establishing the predictable worst-case conditions, the rooftop HVAC equipment

14 Noise Feasibility Study, Mixed Use Development Page Martha Street, Burlington, Ontario September 4, 2014 was assumed to operate at 100% capacity during daytime 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 ) is a computer implementation of ISO Standard 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 attenuation and acoustical shielding by intervening structures such as barriers. 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 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. The unmitigated sound levels due to the rooftop mechanical equipment at the proposed residential development are summarized in the following table. Sound level contours are shown in Figure 4. Table IV: Predicted Sound Levels at Proposed Building [dba], Without Mitigation Receptor Criteria Day/Night Daytime at Façade Night-time at Façade 5 th Floor, West Facade 50 / th Floor, East Facade 50 / th Floor, East Façade 50 / These results indicate that there is potential for sound level excesses under a worst case operational scenario at the proposed residential building on the east façade with exposure to the mechanical equipment of the retirement residence. Conceptual recommendations are provided in the following section.

15 Noise Feasibility Study, Mixed Use Development Page Martha Street, Burlington, Ontario September 4, Discussion and Recommendations With Regard to Existing Stationary Noise Sources Under an assumed worst case operating scenario, the predicted nighttime sound levels may exceed the applicable criteria by up to 2 db on the east façade of the proposed residential building. A shielding structure (such as acoustic parapet wall) with a partial roof is recommended on the roof of the retirement residence to block the line of sight of the unit from all the residential dwellings on the east façades and will likely provide sufficient mitigation. It was observed that there is already a roof screen on the north and east side of the condensing unit on the rooftop of the retirement residence. This roof screen should be extended along the west side of the condensing unit with a partial roof. Figure 5 shows the noted mechanical unit. Prior to site plan approval, a detailed noise study should be conducted by a Professional Engineer qualified to perform acoustical engineering services in the Province of Ontario to confirm that the MOE limits will be met at the proposed residential building and to provide any recommendations which will be required Warning Clause The presence of the neighbouring commercial buildings should be addressed through the implementation of a warning clause in the offers of purchase and sale and tenancy agreements for the residential units in the proposed development. A typical wording is Purchasers are advised of the proximity of adjacent commercial facilities, the sound from which may at times be audible. 7 CONCLUSIONS In summary, HGC Engineering has reviewed the site plan and performed calculations to determine the impact of future road traffic noise on the development, the potential noise impact of the existing commercial uses and retirement home at the proposed residential building and the potential noise

16 Noise Feasibility Study, Mixed Use Development Page Martha Street, Burlington, Ontario September 4, 2014 impact of the proposed development at existing residences with respect to MOE guidelines. The results of the study indicate that the development is feasible from an environmental noise perspective. Assessment of road traffic noise indicates that the proposed residential building will require an alternative means of ventilation to open windows. Central air conditioning systems will be provided to all dwelling units which will satisfy the MOE ventilation requirements. Upgraded glazing constructions are required for the dwelling units facing Lakeshore Boulevard. Noise warning clauses will be required to inform future residents of the traffic noise excesses. Sound levels associated with the rooftop mechanical equipment and parking garage exhaust fans from the proposed building can meet the applicable sound limits at existing residential receptors. A Professional Engineer qualified to perform acoustical engineering services in the Province of Ontario should review the design of the mechanical building systems and the equipment selections when they have been determined, to ensure that the noise levels emitted by the development to the environment are likely to meet the applicable limits. Sound levels from rooftop mechanical equipment associated with the retirement residence located to the east of the site may exceed the applicable sound level limits at the proposed residential units. Additional mitigation measures in the form of a roof screen (extension of the existing screen) will reduce the sound level excesses at the residential building to meet the applicate MOE limits. The reader is referred to previous sections where the recommendations are discussed. A detailed noise study should be conducted by a Professional Engineer qualified to perform acoustical engineering services in the Province of Ontario to confirm that the MOE limits will be met at the residential building and to provide any recommendations which will be required. An additional warning clause should be included in all offers of purchase and sale and tenancy agreements regarding the presences of the nearby commercial facilities and sounds from these facilities may at times be audible.

17 Noise Feasibility Study, Mixed Use Development Page Martha Street, Burlington, Ontario September 4, RECOMMENDATIONS FOR IMPLEMENTATION To ensure that noise control recommendations outlined above are fully implemented, it is recommended: 1) Tarion Builders Bulletin B19R requires that the internal design of condominium projects integrates suitable acoustic features to insulate the suites from noise from each other and amenities in accordance with the OBC, and limit the potential intrusions of mechanical and electrical services of the buildings on its residents. If B19R certification is to be sought, an acoustical consultant is required to review the mechanical and electrical drawings and details of demising constructions and mechanical/electrical equipment, when available, to help ensure that the noise impact of the development on itself are maintained within acceptable levels. 2) Prior to site plan approval, a detailed noise study should be conducted by a Professional Engineer qualified to perform acoustical engineering services in the Province of Ontario to confirm that sound levels associated with the proposed building s rooftop mechanical equipment and parking garage exhaust fans will meet the MOE limits and provide any additional recommendations which may be required. 3) Prior to site plan approval, a detailed noise study should be conducted by a Professional Engineer qualified to perform acoustical engineering services in the Province of Ontario to confirm that sound levels associated with the rooftop mechanical equipment of the retirement residence will meet the MOE limits and provide any additional recommendations which may be required. 4) Before the issuance of building permit, a Professional Engineer qualified to perform acoustical engineering services in the Province of Ontario should review the plans and specifications to certify that the required noise control measures and sound level specifications determined in the detailed noise studies have been included in their entirety.

18 Noise Feasibility Study, Mixed Use Development Page Martha Street, Burlington, Ontario September 4, ) After construction, the municipal 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 implemented and constructed in accordance with the detailed noise studies.
