3 Noise Feasibility Study Page 1 Proposed Redevelopment of Glen Abbey Golf Club, Oakville, ON October 13, Introduction and Summary HGC Engineering was retained by Clublink Corporation ULC and ClubLink Holdings Ld. to conduct a Noise Feasibility Study of the proposed redevelopment of Glen Abbey Golf Club, south of Upper Middle Road West and north and east of Dorval Drive in the Town of Oakville, Ontario. The proposed redevelopment is to include a mix of residential, commercial and open space uses on approximately 230 acres of land. The study is required by the municipality as part of the planning applications process. The primary sources of noise are road traffic on Upper Middle Road West, Dorval Drive and Street A (connecting Dorval Drive and Upper Middle Road West, part of the redevelopment). Ultimate annual average daily traffic data (AADT) was obtained from the Region of Halton for Dorval Drive and Upper Middle Road West. Road traffic data for Street A was provided by BA Group. This data was used to predict future traffic sound levels at the locations of the proposed dwelling facades and in rear yard outdoor living areas. The predicted sound levels were compared to the guidelines of the Ministry of Environment and Climate Change (MOECC). The sound level predictions indicate that noise control measures should be incorporated into the design of the buildings such that indoor sound levels comply with the MOECC noise criteria. Acoustic barriers are required for the rear yards of dwelling units with exposure to Upper Middle Road West. Central air conditioning systems are required for the apartments with exposure to Upper Middle Road West, Dorval Drive and Street A. Forced air ventilation systems with ductwork sized for the future installation of central air conditioning by the occupant is recommended for the townhouse units with exposure to Dorval Drive, Upper Middle Road West and Street A. Upgraded glazing constructions are required for all building façades directly adjacent to and with exposure to Upper Middle Road West. All remaining units may be constructed with any building construction meeting the minimum requirements of the Ontario Building Code (OBC). Warning clauses are also recommended to inform future owners and tenants of the road traffic noise impacts. A detailed noise study should be required when more detailed lotting or phasing information is available.

4 Noise Feasibility Study Page 2 2 Site Description and Noise Sources Figure 1 is a key plan indicating the location of the subject site. The proposed redevelopment is located south of Upper Middle Road West and north and east of Dorval Drive, in Oakville, Ontario. Figure 2 shows the draft plan of the subdivision with block numbers prepared by Glen Schnarr & Associates Inc dated October 4, Figure 3 is the proposed concept plan dated August 17, The sound level prediction locations [A] to [W] for the proposed redevelopment are shown in Figure 3. The proposed residential development will consist of detached units, townhouse units, apartments, retail uses, commercial uses, open space, parks, buffer bocks, natural heritage system block and roadways. HGC Engineering personnel visited the site on January 12, 2016 in order to investigate the acoustic and topographic environment of the site. The site is currently a golf course. The acoustical environment surrounding the site is urban in nature. Surrounding the site are existing residential uses. Upper Middle Road West and Dorval Drive consist of 2 lanes in each direction. Background sound levels from road traffic on Upper Middle Road West and Dorval Drive dominate the site. There are no other significant sources of sound within 500 m of the site. 3 Sound Level Criteria 3.1 Traffic Noise Guidelines for acceptable levels of road traffic noise impacting residential developments are given in the MOECC 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 [LEQ] in units of A-weighted decibels [dba].

5 Noise Feasibility Study Page 3 Space Table I: Road Traffic Noise Criteria Daytime LEQ(16 hour) Road Nighttime LEQ(8 hour) Road Outside Bedroom Windows 55 dba 50 dba Outdoor Living Areas 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, 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 MOECC guidelines. The guidelines in the MOECC publication 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 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. The Region of Halton s minimum noise barrier height is 2.4 m and the maximum height is 3.5 m, based on the Draft Noise Abatement Guidelines dated April The Town of Oakville maximum acoustic fence height is 2.4 m based on the Development Engineering Procedures and Guidelines Manual dated October 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 by the occupant 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 bedroom window sound level is greater than 60 dba or the daytime sound level is greater than 65 dba due to road traffic noise.

6 Noise Feasibility Study Page 4 Warning clauses to notify future residents of possible noise 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. 4 Traffic Noise Assessment 4.1 Road Traffic Data Traffic data for Dorval Drive and Upper Middle Road West was obtained from the Region of Halton in the form of Ultimate Average Annual Daily Traffic (AADT) and is provided in Appendix A. A commercial vehicle percentage of 5% for medium trucks and 3% for heavy trucks was used for both roadways. A day/night split of 90/10% was used along with posted speed limit of 60 km/h for both roadways. Traffic data for Street A connecting Dorval Drive and Upper Middle Road West was provided by BA Group in the form of future AM and PM peak hour volumes. An AADT of vehicles per day for the year 2031 was applied. A commercial vehicle percentage of 1.5% for medium trucks and 1.5% for heavy trucks was assumed in the analysis. A day/night split of 90/10% was used along with assumed speed limit of 50 km/h. Table II summarizes the traffic volume data used in this study.

This modelling software was used to predict the future road traffic sound levels (LEQ) at the building facades. Sample STAMSON output is included in Appendix B. Predictions of the traffic sound levels were made at various locations around the proposed redevelopment. Sound levels were predicted in the plane of the living/dining room and bedroom windows during daytime and nighttime hours to investigate ventilation requirements or at the top storey of the apartment buildings. The results of these predictions are summarized in Table III and Table IV. The acoustic requirements may be subject to modifications if the site plan is changed significantly.

Recommendations to meet the indoor MOECC guidelines are discussed below. 5.1 Outdoor Living Areas The dwelling units in the apartments may include balconies or terraces which are less than 4 metres in depth. These are exempt from the definition of OLA under MOECC guidelines. Physical mitigation is not required.

10 Noise Feasibility Study Page 8 The majority of townhouse units may include decks and patios which are less than 4 metres in depth. These are exempt from the definition of OLA under MOECC guidelines. Physical mitigation is not required. The predicted sound levels in the rear yards of townhouse units with exposure to Upper Middle Road West (prediction location [N]) will be 64 dba. This is 9 dba in excess of the MOECC guideline limit. Physical mitigation is required. A 2.4 m high acoustic fence will reduce the overall sound level in the rear yards to 56 dba. The 1 dba in excess is acceptable to the MOECC, with the use of a noise warning clause. The location of the acoustic barriers is shown in Figure 4. The predicted sound levels in the rear yards of the townhouse units with some exposure to Upper Middle Road West (prediction location [O]) will be 57 dba. A 2.4 m high acoustic fence at the townhouse units with exposure to Upper Middle Road West (prediction location [N]) will reduce the sound levels in the rear yards of units at prediction location [O] to 55 dba. This is acceptable to the MOECC, with the use of a noise warning clause. Physical mitigation is not required. The remaining units away from the major roadways will have rear yards with sound levels less than 55 dba. Physical mitigation is not required. As a general note, acoustic barriers 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/m 2. 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 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. 5.2 Indoor Living Areas The predicted daytime sound levels at apartment buildings with exposure to Dorval Drive (prediction location [D] and [I]), Street A (prediction location ) and Upper Middle Road West (prediction location [Q], [R], [S], [T], [U], [V], [W]) will be greater than 56 dba and greater than 60 dba during nighttime. To address these excesses, MOECC guidelines recommend that all apartment

11 Noise Feasibility Study Page 9 buildings with exposure to Dorval Drive, Street A and Upper Middle Road West be equipped with central air conditioning systems or an alternative means of ventilation to open windows, so that the windows can be kept closed. Window or through-the-wall air conditioning units similar to motelstyle are not recommended because of the noise they produce and because the units penetrate through the exterior wall which degrades the overall sound insulating properties of the envelope unless they are in their own closet with an access door for maintenance. The location, installation and sound ratings of the outdoor air conditioning devices should minimize noise impacts and comply with criteria of MOECC publication NPC-300. Figure 4 indicates the units with central air conditioning. The predicted daytime sound levels at the townhouse dwelling units with exposure to Dorval Drive (prediction location [A], [B], [E], [G]), Street A (prediction location [H], [J] and [K]) and Upper Middle Road West (prediction location [N] and [O]) will be between 55 dba and 65 dba and between 51 and 60 dba during nighttime. These units will require forced air ventilation systems with ductwork sized for the provision for the future installation of central air conditioning systems by the occupant or an alternative means of ventilation to open windows. These units are indicated in Figure 4. The location, installation and sound ratings of the outdoor air conditioning devices should minimize noise impacts and comply with criteria of MOECC publication NPC-300. All remaining units within the redevelopment do not require any specific ventilation requirements. 5.3 Building Façade Constructions The predicted sound levels at apartment building facade with exposure to Upper Middle Road West (prediction locations [S] and [U]) are greater than 65 dba during the daytime due to road traffic. MOECC guidelines recommend that the windows, walls and doors be designed so that the indoor sound levels comply with MOECC noise criteria. The detailed building plans were not yet available for review by HGC Engineering at the time of this study. Preliminary calculations have been performed to determine the building envelope constructions likely to be required to maintain indoor sound levels within MOECC guidelines. The calculation methods were developed by National Research Council (NRC). They are based on the

12 Noise Feasibility Study Page 10 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. In this analysis, it has been assumed that sound transmitted through elements other than the glazing elements is negligible in comparison. Thus, the exterior walls should have sufficient acoustical insulation value such that the noise transmitted through the walls is negligible in comparison with the windows. Exterior walls that include spandrel glass or metal panels within an aluminum window system can have sufficient sound insulation if a drywall assembly on separate framing behind the spandrel panels is used. 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 are to be counted as part of the total window glazing area. All exterior doors should include good weather seals to reduce air (and noise) infiltration to the minimum achievable levels. Units Closest to Upper Middle Road West For the purpose of this preliminary analysis, typical window-to-floor areas were assumed to be 70% (i.e. 50% fixed, 20% operable including glazed sliding patio doors). Based upon these assumptions, it was determined that the glazing along the north façade facing Upper Middle Road must achieve a sound transmission class (STC) rating of at least 30 in order to achieve the target indoor sound level criteria. Awning windows, and swing or sliding doors to balconies should have tight seals sufficient to achieve similar acoustical performance ratings. When detailed floor plans and building elevations for the buildings closest to Upper Middle Road West are available, an acoustical consultant should provide revised recommendations based on actual window to floor area ratios. The remaining facades will have daytime sound levels that are less than 65 dba and less than 60 dba during nighttime. Thus, any exterior wall and double glazed window construction meeting the minimum requirements of the Ontario Building Code (OBC) will provide adequate sound insulation.

13 Noise Feasibility Study Page 11 Remaining Dwelling Units All other remaining townhouse and apartment units will have daytime sound levels that are less than 65 dba and 60 dba during nighttime. For these units, any exterior wall and doubled glazed window construction meeting the minimum requirements of the Ontario Building Code (OBC) will provide adequate sound insulation for the dwelling units. 5.4 Warning Clauses The MOECC guidelines recommend that warning clauses be included in the property and tenancy agreements for all units with anticipated road traffic sound levels. Examples are provided below. Suggested wording for future dwellings with sound levels exceeding the MOECC criteria 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 on occasion interfere with some activities of the dwelling occupants, including any raised patio and/or balcony, as sound levels exceed the sound level limits of the Municipality and the Ministry of the Environment and Climate Change. Suggested wording for future dwellings for which physical mitigation has been provided is given below. Type B: 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 noise criteria of the Municipality and the Ministry of the Environment and Climate Change.

14 Noise Feasibility Study Page 12 Suggested wording for future dwellings requiring forced air ventilation systems is given below. Type C: This dwelling unit has been fitted with a forced air heating system and the ducting etc., was sized to accommodate central air conditioning. Installation of central air conditioning 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 and Climate Change noise criteria. (Note: The location and installation of the outdoor air conditioning device should be done so as to minimize the noise impacts and comply with criteria of MOECC publication NPC-300.) Suggested wording for future dwellings requiring central air conditioning systems is given below. Type D: 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 and Climate Change. The sample clauses are provided by the MOECC as an example and can be modified by the Municipality as required. 6 Summary of Recommendations The following list and Table V and Table VI summarizes the recommendations made in this report. 1. A 2.4 m high acoustic barrier is required for the rear yards of townhouse units with exposure to Upper Middle Road West. 2. Central air conditioning systems will be required for the apartment buildings with exposure to Dorval Drive, Street A and Upper Middle Road West. Forced air ventilation systems with ductwork sized for future installation of central air conditioning systems by the occupant will be required for the townhouse units with exposure to Dorval Drive, Street A and Upper Middle Road West. The location, installation and sound ratings of the air conditioning devices should comply with NPC-300.

15 Noise Feasibility Study Page Upgraded glazing construction will be required for the apartment buildings with exposure to Upper Middle Road West, as indicated in section 5.3. When detailed floor plans are available, an acoustical consultant should provide revised recommendations based on actual window to floor area ratios. 4. Warning clauses should be included in the property and tenancy agreements to inform future owners and tenants of the property of the potential road traffic noise impacts. 5. A detailed noise study is required to revise the acoustic recommendations on a phase by phase basis or when more detailed lotting information is available.
