4 Detailed Noise Study 115 Echo Drive 1.0 INTRODUCTION Novatech has been retained by Uniform Urban Developments to assesses potential noise sources that could affect the proposed development, planned at 113 and 115 Echo Drive is located on the north-east corner of Main Street and Echo Drive in the City of Ottawa, as shown in Figure 1. This study models and analyzes the sound levels, and makes specific recommendations to ensure compliance with the City of Ottawa Environmental Noise Control Guidelines (City of Ottawa, January 2016). The site area is approximately hectares and the proposed development consists of a 6- storey mid-rise condominium building with forty units. The proposed Site Plan, Building Elevation Plans, Floor Plans, and Grading Plan are attached in Appendix C and provides a more detailed layout of the proposed development. 2.0 NOISE CONTROL CRITERIA AND GUIDELINES 2.1 Sound Level Criteria The City of Ottawa is concerned with noise from aircraft, roads, transitways and railways as expressed in Section of the Official Plan. These policies are supported by the Environmental Noise Control Guidelines (ENCG) which is a technical document that outlines the specific sound level criteria, commonly refer to as the Logarithmic Energy Equivalent Continuous Sound Level (L eq). The ENCG has been used as a guideline for this report. When considering noise from surface transportation, proposed noise-sensitive developments must be evaluated within 100m from the right-of-way of an existing or proposed arterial, collector, major collector, light rail transit, or bus transitway; 250m from the right of way of an existing or proposed highway or a Secondary Main railway line; and 500m from the right of way of a freeway, 400 series provincial highway, or Principle Main railway line. For the purposes of this report, Colonel By Drive, Main Street, and Greenfield Avenue are considered arterial roadways and are within 100m of the proposed development thus requiring analysis. Additionally, Highway 417 is a 400-series provincial highway which is within 500m of the site, also requiring analysis. The mandate of acoustical engineering in respect to land-use planning is typically to analyze, and where required, design an acceptable acoustic environment that complies with the ENCG document to the extent that is both reasonable and practical. The areas which must be assessed for acoustic protection include the Outdoor Living Area (OLA); and the Indoor Living Environment, for both living/dining area and sleeping quarters. The Outdoor Living Area (OLA) is defined as that part of the outdoor amenity area provided for the quiet enjoyment of the outdoor environment during the daytime period. These amenity areas are typically backyards, gardens, terraces and patios. The OLA noise target for traffic noise sources is 55 dba. This criterion may be exceeded by an amount not greater than 5 dba, subject to justification and the use of a warning clause. It should be noted that for road, traffic sources, a balcony is not considered an OLA, unless it is the only OLA for the occupant and it is at least 4 m in depth, and unenclosed. Novatech 1

6 Detailed Noise Study 115 Echo Drive The residential Indoor Living Environment (ILE), defined for both living/dining and sleeping quarters, sets noise target for traffic noise sources at 45 dba (day-time) and 40 dba (nighttime), respectively. If this criterion is exceeded, the property may be subject to building component analysis to ensure noise criteria are met and warning clauses. The outdoor sound criterion and indoor sound level criteria are summarized below in Table 2-1. Table 2-1 Outdoor and Indoor Sound Level Criteria Environment Receiver Location and Description Time Period Abbreviation for Report & Modelling ENCG Equivalent Sound Level Criteria, L eq Outdoor Outdoor Living Area Daytime (07:00-23:00 hrs) 16 hour period OLA 55 dba Living/ dining, den areas of residences, hospitals, nursing homes, schools, daycare centres, etc. Daytime (07:00-23:00 hrs) 16 hour period ILED 45 dba Indoor Living/ dining, den areas of residences, hospitals, nursing homes, etc. (except schools or daycare centres) Night time (23:00-07:00 hrs) 8 hour period ILED 45 dba Sleeping quarters Daytime (07:00-23:00 hrs) 16 hour period ILES 45 dba Sleeping quarters Night Time (23:00-07:00 hrs) 8 hour period ILES 40 dba 2.2 Noise Attenuation Requirements When sound levels are predicted to be less than the specified criteria for the daytime and nighttime conditions, no attenuation measures are required by the proponent. As the noise criteria is exceeded, a combination of attenuation measures are recommended by the City of Ottawa to modify the development environment. These attenuation measures may include: Construction of a noise barrier wall; Specified building siting and component design for acoustic insulation; Installation of a forced air ventilation system with provision for central air conditioning; Warning Clauses within Development Agreement(s) and in the Agreement(s) or Offer(s) of Purchase and Sale of prospective home buyers, all of which will be registered on title.

At this particular section of Highway 417 there are 8-lanes for travel; therefore, for this study it was modelled as an 8-lane highway. The parameters to be used for sound level predictions are outlined in the ENCG (Appendix B, Table B1). The roadway noise parameters are summarized below in Table 3-4.

To analysis the noise impact on the proposed building from the aforementioned noise sources, four points of reception were implemented. Figure 2 shows a plan of the receiver locations. To model the effects of floor height changes, Receivers R-A(X), R-B(X), R-C(X), Novatech 4

10 Detailed Noise Study 115 Echo Drive and R-D(X) are identified, whereby X represent Floors 1 to 6. In addition, Receiver R-OA is modelled to represent the rooftop outdoor amenity on Floor 7. The parameters used in STAMSON to assess the noise impacts at the receiver locations can be found below in Table 4.1. It should be noted that, when practical, screening was utilized when the orientation of the proposed development and the noise sources permitted. For Noise Source 3 the existing 2-story residential buildings along Greenfield Avenue were incorporated into the STAMSON model as a 7.0 m high barrier. At Noise Source 4 the existing 3.0 m high noise wall along the perimeter of the 417 Highway was used. To be conservative, no further screening from existing buildings surrounding the development was included in this noise assessment. Noise modeling was undertaken for the following environments: OLAs As per the architect s building floor plans which have been provided in Appendix C, the balconies located on Floors 1 to 5 do not qualify as OLAs, since they are generally less than 4.0 m in depth. However, the balconies located on Floor 6 are much larger and do warrant an OLA assessment. Receivers R-A(6), R-B(6), R-C(6), and R-D(6), are modelled to represent Floor 6 balconies. For the rooftop amenity on Floor 7, it has been identified as R-OA. The noise levels are calculated at the receivers which are located 3.0 m from the building face as per the City of Ottawa ENCG. It is being proposed that these balconies are to include a parapet wall (or guardrail), which provides a solid barrier wall for both safety purposes and for noise attenuation, provided this building component has a surface mass density of 20 kg/m 2. The proposed height of the barrier wall is 1.1 m. ILEs As per the architect s building floor plans, the worst-case scenarios for both ILE day-time and night-time receivers were modelled at the plane of window in closest proximity to the noise source. The modelling considered receivers at each floor, although in practice, due to the reflective nature of the ground noise surface, the sound levels will likely be identical at all floors along the modelled building face.

(ii) 'X' denotes the variable floor elevations + receiver height/ receiver elevation (m). Refer to Appendix C for the elevation plans. As outlined in Table 2-1, the target noise level for the OLA is 55 dba, with a provision of an additional 5 dba tolerance subject to justification and the use of a warning clause. For the established OLA s within this proposed development, which include the balconies on Floor 6 and the rooftop amenity on Floor 7, the day-time noise levels fall below the maximum permitted outdoor living area noise level when implementing the parapet wall. Refer to further discussions in Section 5.1 of this report. Furthermore, the target noise levels for the ILE, also outlined in Table 2-1, for both living/dining area and sleeping quarters is 45 dba and 40 dba, respectively. To mitigate these sound levels, additional building component analysis is required to ensure noise criteria are met. Refer to further discussions in Section 5.2 of this report. To avoid the noise intrusion through open windows or doors due to summer heat, the installation of a forced air ventilation system with provisions for central air conditioning may be required. Refer to further discussions in Section 5.3 of this report. Notwithstanding the outdoor and indoor mitigations, the inclusion of warning clauses within the Development Agreements, Agreements of Purchase and Sale, or Agreements of Lease of prospective home buyers/ leases is recommended. Refer to further discussions in Section 5.4 of this report. 5.0 NOISE LEVEL ATTENUATION MEASURES 5.1 Outdoor - Proposed Noise Barrier To meet the required OLA noise level of 55 dba (day-time), a parapet wall (or guardrail) is being proposed for the Floor 6 balconies and Floor 7 rooftop amenity. It is recommended that the wall be constructed around the perimeter of the terrace and have a surface mass density not less than 20 kg/m² to comply with the City Standard and to provide adequate noise attenuation. As shown in the tables in Section 4.2 of this report, the noise levels at the specified OLA s with a 1.1 m high parapet wall provide adequate noise attenuation. No further measures are required. Novatech 7

13 Detailed Noise Study 115 Echo Drive 5.2 Indoor - Proposed Building Component Assessment When ILE noise levels exceed 45 dba (day-time) or 40 dba (night-time), the exterior shell system of the building envelope must be acoustically assessed to ensure the indoor noise criteria is achieved. Based on the results of Table 4-2, in the proposed development the sound levels at various receiver locations are above both the day-time and night-time allowance. Therefore, additional analysis of the cladding system is warranted. To comply with the ENCG policies, the building envelope will require a minimum Acoustic Insulation Factor (AIF) or Sound Transmission Class (STC) rating to provide the desired indoor noise levels as shown above in Table 2-1. Per common industry practice, complete walls and individual wall elements are rated per the STC value. The STC ratings of common residential walls built in conformance with the Ontario Building Code typically exceed STC 35; and standard good quality double-glazed non-operable windows can have STC ratings ranging from 25 to 40 depending on the manufacturer, components, glazing or air spaces thickness, and seal materials. AIF Method and Approximate STC Equivalent The required AIF is based on the outdoor mitigated noise levels (Outdoor L eq), ENCG indoor noise criterion indoor (Indoor L eq), and the number of façade components that make up the exterior shell. In practice, the exterior shell is comprised of primarily two components; windows (patio doors are treated as windows) and exterior walls. The Canada Mortgage and Housing Corporation (CMHC) Standards 1 provide guidance on the desired AIF ratings for different exterior shell components. Tables from the document entitled Acoustic Insulation Factor: A Rating for the Insulation of Buildings Against Outdoor Noise, produced by the Division of Building Research, National Research Council of Canada, June 1980 (J.D. Quirt) were used to assess the exterior facade against the required AIF. This reference material is included in Appendix B. The required AIF for the desired building facade analysis is calculated as follows: AIF = Outdoor L eq Indoor L eq + {10 x log 10 (N)} dba + 2dBA Where, N = Number of components (typically 2, i.e. windows and exterior walls); L eq = Sound Level Equivalent expressed on a common decibel scale. Example Receiver R - C(1): ILES-16 Day-time AIF = dba 45 dba + {10 x log 10 (2)} dba + 2dBA = dba ILES-8 Night-time AIF = dba 40 dba + {10 x log 10 (2)} dba + 2dBA = dba Based on the above results and to comply with the ENCG policies, the building components will require a minimum AIF rating of 31 to provide the appropriate indoor noise levels. The AIF can further be approximated to an STC equivalents, if floor plans are available. Based on preliminary building floor plans, window-to-floor ratios are between 40% and 63%. Accordingly, the AIF rating of 31, is equivalent to an STC rating of 33, 34, 35, for units having a window-to-floor ratio of 40%, 50%, and 63%, respectively. Likewise, wall-to-floor ratios are also between 40% and 63%. The AIF rating of 31, is equivalent to an STC rating of 34, 35, 36, for 1 Road and Rail Noise: Effects on Housing, CMHC, Ottawa. Publication NHA #185 1/78, 1978 Novatech 8

14 Detailed Noise Study 115 Echo Drive units having a wall-to-floor ratio of 40%, 50%, and 63%, respectively. The AIF to STC approximate equivalency tables can also be found in Appendix B. STC Method For more detailed analysis, the required STC is based on the outdoor noise levels (Outdoor L eq) minus the ENCG indoor noise criterion indoor (Indoor L eq). In practice, the exterior shell is comprised of primarily two components; windows (patio doors are treated as windows) and exterior walls. The Canada Mortgage and Housing Corporation (CMHC) Standards 2 provide guidance on the desired ratings for different exterior shell components. Tables and worksheets from the document entitled Building Practice Note: Controlling Sound Transmission into Buildings, produced by the Division of Building Research, National Research Council of Canada, September 1985 (J.D. Quirt) were used to determine the required STC for the exterior facade. This reference material is included in Appendix B. Results of the required STC for the desired building façade has been summarized in Table 5-1. Table 5-1 STC for the Building Façade Summary Location Typ. Unit Window/ Floor Ratio (%) Typ. Unit Exterior Wall/ Floor Ratio (%) Required Window STC Required Wall STC Floor Floors Floor Please note that the required window and wall STC values were determined based on preliminary building floor plans. Once the building floor plans have been finalized, the building components should be reviewed by an acoustical engineer to ensure that the components will provide acceptable indoor noise levels to comply with the ENCG guidelines. 5.3 Provision for Central Air Conditioning To provide indoor isolation and avoid noise intrusion through open windows or doors, the installation of a forced air ventilation system with provision for central air conditioning may be required. It is proposed to install central air conditioning for all units within this condominium building to allow the homeowners to keep the windows and exterior doors closed, ensuring the indoor sound levels are within the noise criteria. 5.4 Proposed Warning Clauses If noise levels are expected to exceed the applicable ENCG sound level criteria, the City of Ottawa recommends a warning clause be registered on title and incorporated into the Subdivision Agreement and in the Agreement of Purchase and Sale. The warning clause serves to alert potential buyers and/or renters of the possible noise condition and of any limitations that may exist on his/her property rights. Based on the noise modelling, a sample of these warning clauses are listed below. Table 5-2 provides a tabulated approach to summarize warning clauses required for each lot. 2 Road and Rail Noise: Effects on Housing, CMHC, Ottawa. Publication NHA #185 1/78, 1978 Novatech 9

15 Detailed Noise Study 115 Echo Drive Warning Clause Type A Purchasers/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 City s and the Ministry of the Environment s noise criteria. Warning Clause 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 and transitway traffic may on occasion interfere with some activities of the dwelling occupants as the sound levels exceed the City s and the Ministry of the Environment s noise criteria. Warning Clause 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 by the occupant will allow windows and exterior doors to remain closed, thereby ensuring that the indoor sound levels are within the City s and the Ministry of the Environment s noise criteria. (Note: The location and installation of the outdoor air conditioning device should be done so as to comply with noise criteria of MOE Publication NPC-216, Residential Air Conditioning Devices and thus minimize the noise impacts both on and in the immediate vicinity of the subject property.) Warning Clause Type D 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 City s and the Ministry of the Environment s noise criteria.
