3 18 McArthur Avenue N INTRODUCTION AND SUMMARY Arch-Nova was retained to investigate the potential impact of environmental noise impact on the proposed development located at 18 McArthur Avenue in Ottawa Ontario. The assessment is based on the proposed building design, existing and future traffic noise sources, and the environmental noise guidelines of the Ministry of the Environment and Climate Change ( MOECC ) and the City of Ottawa. A noise study is required by the municipality as part of the planning and approvals process. This report was prepared based on a Site Plan prepared by SOMA PRO Design architects, dated March 14, The proposed development building consists of basement, three (3) storeys and a penthouse. The basement and the 1 st through the 3 rd floor will contain two residential units on each floor, and the penthouse will contain administrative office and tenant storage. There is a communal outdoor living area (OLA) associated with the proposed development located on the roof and backyard are identified amenities as defined as OLA under City of Ottawa or MOECC guidelines. The site is bounded by existing residential to the west, south and east, and commercial lands to the north. Further to the west, across the road, there are mixed commercial and residential lands. Figure 1 shows the proposed site including the aerial view of the surrounding area. Zoning map for the surrounding area is attached in Appendix A. 2.0 ENVIRONMENTAL NOISE ASSESSMENT The main environmental noise sources external to the project which were identified and have the potential to adversely affect the development are motor vehicle traffic noise along McArthur Avenue, North River Road and Vanier Pkwy.

4 18 McArthur Avenue N Traffic Noise Sources Road Traffic Road traffic associated with McArthur Avenue is the dominant environmental noise source in the vicinity of the proposed development. Secondary noise sources will include traffic on North River Road and Vanier Pkwy. Fully developed (2025) road traffic data was used in the analysis. Current traffic data for McArthur Avenue at North River Road, McArthur Avenue at Marguerite, and McArthur Avenue at Vanier Parkway were provided by City of Ottawa transportation department. As per the City of Ottawa transportation department, no traffic data was available for other smaller streets in the close proximity to the project site. Based on the physical location and residential density of the street, it was conservatively assumed the minimum traffic counts available in modeling software as recommended by the City of Ottawa Environmental Noise Control Guidelines. In addition, a yearly growth rate of 2.5% was used to calculate the traffic data. In order to calculate the fully developed road traffic volumes, numbers were grown to the year Traffic data was split into daytime/nighttime and autos/medium/heavy using City of Ottawa Environmental Noise Control Guidelines. Posted speed limits were used in the analysis. Data used in the noise modelling are found in Table 1. Table 1: Year 2026 Road Traffic Data Used in Analysis Street Time of Day Vehicles Medium Trucks Heavy Trucks Total McArthur Avenue North River Road Vanier Pkwy Total Total Total Provided road traffic data and road traffic calculations used for the study are included in Appendix B Rail Traffic Rail line is located beyond 1000 metres from the proposed development, which is out of zone of influence as per City of Ottawa Noise Protocol. Therefore, no further assessment was performed. Arch-Nova Design Inc. Page 3

5 18 McArthur Avenue N Air Traffic Proposed project is located outside of Airport Vicinity Development Zone and out of the zone of influence from the Airport Operating Influence Zone (AOIZ) and NEF/NEP contours lines. Therefore, no further assessment was performed. 2.2 Stationary Noise Sources Based on investigation of the surrounding areas, there are no potential stationary industrial sources of noise in the vicinity of the proposed development. The MOECC D-series guidelines were developed as guidance for recommended separation distances and other control measures for land use planning proposals to prevent or minimize adverse effects from the encroachment of incompatible land uses where a facility either exists or is proposed. Additionally, the MOECC developed the noise guidelines for stationary source noise impacting residential developments called the MOECC Publication NPC-300 Stationary and Transportation Sources Approval and Planning Since no industrial sources are located in the vicinity of the proposed development, neither the D-series guidelines nor NPC-300 have been considered further in this study. 3.0 TRAFFIC NOISE IMPACT 3.1 Applicable Noise Guideline City of Ottawa noise guidelines for transportation noise impacting residential developments are given in the publication City of Ottawa Environmental Noise Control Guidelines (Appendix E). A summary of the City of Ottawa noise requirements is provided Table 2 below. Arch-Nova Design Inc. Page 4

Provision for central air conditioning 50 to 60 [3] Plane of + warning clause Window > 60 [3] Central air conditioning + warning clause Living Area Sleeping Area If Central AC is required, facade must be designed to meet these levels [2] The criterion may be exceeded by an amount not greater than 5 dba, subject to justification and use of a Warning Clause. [3] If façade levels exceed these criteria, building components must be designed to meet Indoor Criteria. For OLAs, a design goal of 55 dba L EQ,day is required. An unmitigated sound exposure due to road traffic of up to 60 dba is considered a minor excess and is permissible, provided a warning clause advising the occupant of the potential noise levels is used. A sound exposure greater than 60 dba must be reduced to 60 dba or less using physical mitigation methods such as berms or barriers, or combination of both. A central air conditioning system as an alternative means of ventilation to open windows is required for spaces where nighttime sound levels outside sensitive space windows exceed 60 dba or where daytime sound levels outside sensitive space windows exceed 65 dba. Forced-air ventilation with ducts sized to accommodate the future installation of air conditioning is required when nighttime sound levels at sensitive space windows are in the range of 51 to 60 dba or when daytime sound levels at sensitive space 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 sound level is greater than 60 dba or the daytime sound level is greater than 65 dba due to road traffic noise and when the Arch-Nova Design Inc. Page 5

7 18 McArthur Avenue N plane of window sound level is greater than 55 dba due to rail traffic noise. The use of warning clauses to notify future occupants of possible excesses is also recommended. 3.2 Traffic Noise Impact Assessment L EQ,night and L EQ,day attributable to McArthur Avenue, North River Road and Vanier Pkwy were calculated using STAMSON v5.0, the computerized road, rail, and transit traffic noise prediction model of the MOECC. Since the City of Ottawa requires projected sound exposures be based on ultimate traffic volumes for roadways, sound exposure levels were based on 2026 (future) road traffic predictions. Screening due to surrounding buildings and terrain was accounted for in the analysis, if applicable. The proposed development will have three (3) floors above the ground level and partial in ground level, identified as basement. It was assumed, that if the noise impact levels at the 1 st and 2 nd floor are acceptable (sensitive spaces with larger exposure), the rest of the upper floor units will be satisfied as well. Table 3 summarizes the predicted unmitigated daytime and nighttime sound exposures levels at predictable worst-case locations at the proposed development. Sample sound exposure calculation and analysis assumptions are included in Appendix D.

Page 7

9 18 McArthur Avenue N represent the OLA as part of a proposed future development. Analysis confirmed that the noise levels are acceptable at the proposed OLA (Ref. Table 3) Indoor Sensitive Area All floors on the north of the proposed development have predicted nighttime sound levels that are greater than 50 dba but less than 60 dba. To address these excesses, the City of Ottawa Environmental Noise Control Guidelines and MOECC guidelines recommend that these dwelling units be equipped with a forced air ventilation systems with ducts sized to accommodate the future installation of air conditioning by the occupant. Window or through-the-wall air conditioning units are not recommended for any sensitive spaces because of the noise they produce and because the units penetrate through the exterior wall which degrades the overall noise insulating properties of the envelope. The location, installation and sound ratings of the outdoor air conditioning devices should minimize noise impacts and comply with criteria of MOECC publication NPC-216, Residential Air Conditioning Devices. 4.3 Building Façade Construction All floors in the development will have nighttime sound levels at the façade that are less than 60 dba and daytime sound levels at the façade that are less than 65 dba. Therefore, any exterior wall, and double glazed window construction meeting the minimum requirements of the Ontario Building Code (OBC) will provide adequate sound insulation for all façades of dwelling units. 4.4 Warning Clauses The City of Ottawa Environmental Noise Control Guidelines and MOECC guidelines recommend that warning clauses be included in the property and tenancy agreements and offers of purchase and sale for dwelling units with anticipated traffic sound level excesses. Examples are provided below. Suggested wording for future development which has sound level excesses but do not require mitigation measures is given below. Type A: Purchasers/tenants are advised that sound levels due to increasing road and rail traffic may occasionally interfere with some activities of the dwelling unit occupants as the Arch-Nova Design Inc. Page 8

10 18 McArthur Avenue N sound levels exceed the Municipality s and the Ministry of the Environment s noise criteria. Suitable wording for proposed development building requiring forced air ventilation systems is given below. Type C: Purchasers/tenants are advised that 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 City s and the Ministry of the Environment s noise criteria. Purchasers/tenants are advised that the outdoor air cooled condenser unit itself can produce noise to interfere with outdoor recreational activities. Due consideration should be given to this noise factor when selecting the air cooled condenser units location or an alternative quieter type of unit could be selected. The condenser unit sound rating should not exceed 7.6 bels in accordance with ANSI Standard for units 3.5 ton or less. The location and installation of the outdoor air conditioning device should be done so as to minimize the noise impacts and have due regard for compliance with criteria of MOECC publication NPC-216, Residential Air Conditioning Devices. 5.0 CONCLUSION The noise feasibility study was conducted to meet the noise guidelines developed by the City of Ottawa and the MOECC under Guideline D-6 and NPC-300. Noise impacts at the proposed development have been evaluated and are predicted to meet MOECC and City of Ottawa noise requirements. No noise abatement measures are reuired. However, warning clauses advising the future occupants of the potential noise impacts will be required. The proposed development is considered feasible from an environmental noise impact perspective.
