NOISE ASSESSMENT REPORT Introduction February 8, 2016 1.0 INTRODUCTION 1.1 PURPOSE OF REPORT Stantec Consulting Ltd. has been retained by TC United Group to prepare an environmental noise assessment for the proposed 3 storey student apartment at 176 Greenfield Avenue, located in Ottawa East in the City of Ottawa. A site plan control application is being prepared and a Noise Assessment Study is required to address City policies regarding residential development adjacent to highways and arterial roads. The purpose of this report is to: outline the Ministry s guidelines and criteria for noise levels and residential land use; apply the noise level standards of the Ontario Ministry of the Environment to the site in conjunction with the City of Ottawa document Environmental Noise Control Guidelines (2006); determine the extent to which noise levels will be of concern to future residents of the proposed development, using the computerized version (STAMSON 5.03) of the M.O.E. s noise model; and outline recommendations for noise attenuation, as necessary, to achieve acceptable noise levels for future residents of the proposed development. This report has been revised to reflect City of Ottawa Comments received on January 21, 2016. 1.2 LOCATION The site is located along Greenfield Avenue, east of Main Street and north of Highway 417. The proposed site is illustrated in Figure 1. The proposed development consists of 6-bedroom suites on each floor including common living area. This report will focus on the rooms with exposure to Greenfield Avenue, Main Street and Highway 417. Surrounding land uses are as follows: north existing residential east existing residential south existing residential and Highway 417 west existing residential and commercial The main potential noise source that may impact the subject site is vehicular traffic and the volumes for these roadways are based on the City of Ottawa document Environmental Noise Control Guidelines. 1

NOISE ASSESSMENT REPORT Noise Level Criteria February 8, 2016 Figure 1 176 Greenfield Avenue Development 176 Greenfield Ave 2.0 NOISE LEVEL CRITERIA 2.1 GUIDELINES The Ontario Ministry of Environment (M.O.E.) has produced guidelines for noise levels for use in noise assessment and land use planning. Noise level criteria for residential land use are summarized in Table 1 below. Noise levels in excess of the guidelines presented are acceptable under certain conditions and with certain provisions. 2

NOISE ASSESSMENT REPORT Observations and Calculations February 8, 2016 3.0 OBSERVATIONS AND CALCULATIONS 3.1 NOISE LEVEL PREDICTIONS Noise predictions in this report were completed using the computerized version (STAMSON 5.03) of the M.O.E. noise model ORNAMENT to calculate noise levels from various sources. The program accepts variables related to noise sources and receivers, road traffic volumes, and the nature and extent of noise mitigation features, if required. 3.2 ROAD TRAFFIC VOLUMES Traffic volume data for Greenfield Avenue, Main Street and Highway 417 were provided by the City of Ottawa document Environmental Noise Control Guidelines. The document indicates that the average annual daily traffic volume for Greenfield Avenue and Main Street will be 15,000 vehicles per day for a 2-lane urban arterial and Highway 417 will be 146,664 vehicles for an 8-lane highway. Additional information regarding applicable assumptions and ratios for day/night traffic and car/ truck traffic is summarized as follows: heavy truck traffic for this segment is estimated to be 5% of total traffic volume; medium truck traffic for this segment is estimated to be 7% of total traffic volume; the rest is assumed to be car traffic; daytime (7 am 11 pm) traffic is assumed to be 92%, with the remaining 8% at night (11 pm 7 am); and the speed limit for Greenfield Avenue and Main Street is 50 km/hr and Highway 417 is 100 km/h Table 5 and Table 6 summarize the traffic volumes used for calculations in this report.

The resulting receiver sites are illustrated in Figure 2 and Figure 3 and the noise clauses are illustrated in Figure 4 through Figure 6. The receiver heights for indoor, daytime, and nighttime noise level calculations for the proposed buildings were completed at the mid-height of each floor. To account for the distance from the receivers along Greenfield Avenue that were under 15 metres, the Ornament methodology outlined in Section 5.5 of the Ornament Technical Document was applied. This distance adjustment factor is based on a reference 15.0 m receiversource distance and applied to generate the Ornament output for typical receivers. While it was developed for distances between 15.0m and 500.0m, it is felt that it will closely approximate distances slightly below 15.0m. The adjustment factor will be added to the 15.0m noise level to increase the resultant noise level for mitigation purposes. The adjustment factor calculation if as follows: 6

NOISE ASSESSMENT REPORT Conclusions and Recommendations February 8, 2016 4.0 CONCLUSIONS AND RECOMMENDATIONS 4.1 NOISE IMPACTS Predicted noise levels are above City of Ottawa and M.O.E. criteria at the daytime building face and the nighttime building face for potential units with exposure to Greenfield Avenue, Main Street and Highway 417. The following summarizes the measures required by the City of Ottawa and MOE criteria for the development to occur within accepted standards: Noise Warning Clause A is to be included in all offers of purchase and sale for the site due to the economic and technical feasibility of providing mitigation to Highway 417. Central air conditioning is to be installed in the building, inclusive of all floors. Noise Warning Clause D is to be included in all offers of purchase and sale of the building, inclusive of all floors. Noise warning clauses are provided in Appendix B. 4.2 INDOOR NOISE MITIGATION AIF METHOD For the floors and rooms requiring Noise Warning Clause D, the following building components will apply based on the Acoustical Insulation Factor (AIF) method, as per Environmental Noise Assessment in Land Use Planning Manual, 1999. The AIF value and minimum building component were based off the preliminary unit floor plans. The calculated noise levels requiring mitigation were 68.1 dba at the north side of the building during the daytime and 59.4 dba at the south side of the building during the nighttime. These noise levels were used to determine the typical building components required for the building façade. Table 9 summarizes the AIF values and minimum building components and Appendix C provides the floor plans and sample calculations.

In this situation, double glazed windows with 2mm thickness and various spacing outlined above would be required the building. Windows with an equivalent AIF may be substituted for the recommended thickness, glazing and spacing. E.g. a double glazed 3mm pane with 6mm spacing may be substituted for double glazed 2mm panes with 15mm pacing. 14

NOISE ASSESSMENT REPORT Conclusions and Recommendations February 8, 2016 *EW1 construction consists of: 12.7 mm gypsum board, vapour barrier, and 38x89 studs with 50 mm mineral wool or glass fibre batts in inner stud cavities. As well as sheathing and wood siding or metal siding and fibre backer board. Should the actual floor plans differ from the plans shown in Appendix C, updated calculations must be performed prior to the issuance of building permits. The inclusion of these measures will allow the residential development to proceed in accordance with MOE criteria with respect to environmental noise.
