2 EXECUTIVE SUMMARY This document describes a roadway traffic noise impact study for three proposed buildings that form part of a single development located at 383 Slater Street / 400 Albert Street in downtown Ottawa, Ontario. The three towers are known as Towers A, B, and C, and are 10, 27, and 27 storeys above grade, respectively. Tower A is nearest to Albert Street, located north on the site; Tower B is nearest to Bay Street and Slater Street on the southwest corner of the site; Tower C is nearest to Slater Street and Lyon Street on the southeast corner of the site. Figure 1 illustrates a site plan with surrounding context. The major source of noise affecting the development is roadway traffic along Albert Street, Slater Street, and Lyon Street. The assessment is based on: (i) theoretical noise prediction methods that conform to the Ministry of the Environment and Climate Change (MOECC) and City of Ottawa requirements; (ii) noise level criteria as specified by the City of Ottawa s Environmental Noise Control Guidelines (ENCG); (iii) future vehicular traffic volumes based on the City of Ottawa s Official Plan roadway classifications; and (iv) architectural drawings received from Woodman Architect & Associates Ltd. The results of the current study indicate that the dominant source of noise impacting the site is due to roadway traffic. Noise levels from roadway traffic will range between approximately 50 and 70 dba during the daytime period (07:00-23:00) and between 42 and 62 dba during the nighttime period (23:00-07:00). The highest noise level (i.e. 70 dba) occurs along the south and east façades of Tower C. Upgraded building components with higher sound attenuation properties are required where noise levels exceed 65 dba, as indicated in Figures 3-4. In addition to upgraded building components, all units in Towers A, B, and C will require air conditioning (or similar mechanical system), which will allow occupants to keep windows closed and maintain a comfortable living environment. In addition to ventilation requirements, it will also be required to include Warning Clauses in all Lease, Purchase and Sale Agreements, as summarized in Section 6.

4 1. INTRODUCTION Gradient Wind Engineering Inc. (GWE) was retained by Manor Park Management to undertake a traffic noise impact study for three proposed buildings that form part of a single development located at 383 Slater Street/400 Albert Street in Ottawa, Ontario. This report summarizes the methodology, results, and recommendations related to a roadway traffic noise assessment. GWE s scope of work involved assessing exterior and interior noise levels generated by local roadway traffic, throughout the site. The assessment was performed on the basis of theoretical noise calculation methods conforming to the City of Ottawa 1 and Ontario Ministry of the Environment and Climate Change (MOECC) 2 guidelines. Noise calculations were based on architectural drawings provided by Woodman Architect Inc., with future traffic volumes corresponding to the City of Ottawa s Official Plan (OP) roadway classifications. 2. TERMS OF REFERENCE The focus of this roadway traffic noise impact study is the proposed mixed-use, multi-building, development to be located at 383 Slater Street/400 Albert Street in Ottawa, Ontario. The site is situated on a parcel of land bounded by Albert Street to the north, Lyon Street north to the east, Slater Street to the south, and Bay Street to the west. In the near-field, the site is surrounded by the urban environment of downtown Ottawa, with the exception of the Nanny Goat Hill Community Garden to the southwest west. The proposed development features three buildings, referred to as Blocks A, B, and C, located on the north, southwest, and southeast portions of the site, respectively. The three buildings share four levels of underground parking, accessed from Bay Street, at the northwest corner of Block B. Block A is a 10-storey hotel, rising meters, measured from grade to the top of the roof slab. The main hotel entrance is along Albert Street, at the centre of the north elevation. The building features an exterior dining terrace at the ground floor and a rooftop terrace serving as an outdoor living area. Blocks B and C both feature 27-storey towers, which reach a height of meters, measured from grade to the top of the mechanical penthouse. The towers rise above six-storey podia with rectangular planforms, the long axis aligned in the east-west directions. At grade, Block B contains a residential lobby accessible from the south elevation and retail space accessible from the east elevation. Block C contains 1 City of Ottawa, Environmental Noise Control Guidelines, January Ontario Ministry of the Environment and Climate Change Publication NPC-300 Manor Park Management 383 Slater Street / 400 Albert Street, Ottawa: Roadway 1

5 a residential lobby accessible from the east elevation and retail spaces accessible from the east and west elevations. There is a rooftop terrace serving as an outdoor living area above the 6 th floor of Tower C. The major source of noise is roadway traffic along Albert Street, Lyon Street, and Slater Street. The site is surrounded with a mix of residential and commercial, low to high-rise buildings. Figure 1 illustrates a complete site plan with surrounding context. 3. OBJECTIVES The main goals of this work are to: (i) calculate the future noise levels on the study buildings produced by local roadway traffic, (ii) ensure that interior noise levels do not exceed the allowable limits specified by the City of Ottawa s Environmental Noise Control Guidelines (ENCG) as outlined in Section 4.2 of this report. 4. METHODOLOGY 4.1 Background Noise can be defined as any obtrusive sound. It is created at a source, transmitted through a medium, such as air, and intercepted by a receiver. Noise may be characterized in terms of the power of the source or the sound pressure at a specific distance. While the power of a source is characteristic of that particular source, the sound pressure depends on the location of the receiver and the path that the noise takes to reach the receiver. Measurement of noise is based on the decibel unit, dba, which is a logarithmic ratio referenced to a standard noise level ( Pascals). The A suffix refers to a weighting scale, which better represents how the noise is perceived by the human ear. With this scale, a doubling of power results in a 3 dba increase in measured noise levels and is just perceptible to most people. An increase of 10 dba is often perceived to be twice as loud. 4.2 Criteria for Roadway Traffic Noise For surface transportation, the equivalent sound energy level, L eq, provides a measure of the time varying noise levels, which is well correlated with the annoyance of sound. It is defined as the continuous sound level, which has the same energy as a time varying noise level over a period of time. For roadways, the L eq is commonly calculated on the basis of a 16-hour (L eq16) daytime (07:00-23:00) / 8-hour (L eq8) nighttime (23:00-07:00) split to assess its impacts on buildings. Table 1 below describes the applicable indoor noise level limits for both roadway and railway. The City of Ottawa s ENCG specifies that the recommended indoor noise limit range (that is relevant to this study) is 45 and 40 for residence living/dining areas and Manor Park Management 383 Slater Street / 400 Albert Street, Ottawa: Roadway 2

6 sleeping quarters respectively, as listed in Table 1. Based on GWE s experience, more comfortable indoor noise levels should be targeted toward 42 and 37 dba to control peak noise, and deficiencies in building envelope construction. TABLE 1: INDOOR SOUND LEVEL CRITERIA (ROAD & RAIL) 3 Type of Space Time Period Road L EQ (dba) Rail General offices, reception areas, retail stores, etc. 07:00 23: Living/dining/den areas of residences, hospitals, schools, nursing/retirement homes, day-care centres, theatres, places of worship, libraries, individual or semi-private offices, conference rooms, etc. 07:00 23: Sleeping quarters of hotels/motels 23:00 07: Sleeping quarters of residences, hospitals, nursing/retirement homes, etc. 23:00 07: Predicted noise levels at the plane of window (POW) dictate the action required to achieve the recommended sound levels. An open window is considered to provide a 10 dba reduction in noise, while a standard closed window is capable of providing a minimum 20 dba noise reduction. Therefore, where noise levels exceed 55 dba daytime and 50 dba nighttime, the ventilation for the building should consider the need for having windows and doors closed, which normally triggers the need for central air conditioning (or similar systems). Where noise levels exceed 65 dba daytime and 60 dba nighttime, building components will require higher levels of sound attenuation. 3 Adapted from ENCG Table 1.6 Manor Park Management 383 Slater Street / 400 Albert Street, Ottawa: Roadway 3

7 4.3 Roadway Noise Assessment Theoretical Roadway Traffic Noise Predictions Noise predictions were performed with the aid of the MOECC computerized noise assessment program, STAMSON 5.04, for road analysis. Appendix A includes the STAMSON 5.04 input and output data. Roadway noise calculations were performed by treating each road segment as separate line sources of noise, and by using existing building locations as noise barriers. In addition to the traffic volumes summarized in Table 2 below, theoretical noise predictions were based on the following parameters: Truck traffic on all roadways was taken to comprise 5% heavy trucks and 7% medium trucks, as per ENCG requirements for noise level predictions The day/night split was taken to be 92% / 8% respectively for all streets Absorptive and reflective intermediate ground surfaces based on specific source-receiver path ground characteristics The study site was treated as having flat/gently sloping topography In some cases, the building is closer than 15 m to the centreline of the roadway. It should be noted that the minimum distance which can be specified in STAMSON is 15 m. Noise levels within this distance are not expected to vary significantly and the only acceptable noise model for use by the City of Ottawa is STAMSON. Noise receptors were strategically identified at 30 locations around the study area, as illustrated in Figure Roadway Traffic Volumes The ENCG dictates that noise calculations should consider future sound levels based on a roadway s classification at the mature state of development. Therefore, traffic volumes are based on the roadway classifications outlined in the City of Ottawa s Official Plan (OP) and Transportation Master Plan 4, which provide additional details on future roadway expansions. Average Annual Daily Traffic (AADT) volumes are then based on data in Table B1 of the ENCG for each roadway classification. Table 2 (below) summarizes the AADT values used for each roadway included in this assessment. 4 City of Ottawa Transportation Master Plan, November 2013 Manor Park Management 383 Slater Street / 400 Albert Street, Ottawa: Roadway 4

The difference between outdoor and indoor noise levels is the noise attenuation provided by the building envelope. According to common industry practice, complete walls and individual wall elements are rated according to the Sound Transmission Class (STC). The STC ratings of common residential walls built in conformance with the Ontario Building Code (2012) typically exceed STC 35, depending on exterior cladding, thickness, and interior finish details. For example, brick veneered walls can achieve STC 55. Standard good quality double-glazed non-operable windows can have STC ratings ranging from 25 to 40, depending on the window manufacturer, pane thickness, and inter-pane spacing. As previously mentioned, windows are the known weak point in a partition. When daytime noise levels (from road and rail sources) at the plane of the window exceed 65 dba, calculations must be performed to evaluate the sound transmission quality of the building components to ensure acceptable indoor noise levels. As a guideline, the anticipated STC requirements for windows have been estimated based on the overall noise reduction required for each intended use of space (STC = outdoor noise level targeted indoor noise levels). Note the City of Ottawa may require detailed window STC calculations be competed prior to building permit based on window sizes and floor plan layouts.

RESULTS AND DISCUSSION 5.1 Roadway Traffic Noise Levels The results of the roadway noise calculations are summarized below in Table 3 for receptors identified at the various heights, as well as for two outdoor living areas (OLA). Appendix A contains the complete set of input and output data from all STAMSON 5.04 calculations. The results of the current study indicate that noise levels due to roadway traffic over the site will range between 50 and 70 dba during the daytime period (07:00-23:00) and between 42 and 62 dba during the nighttime period (23:00-07:00). The highest noise level (i.e. 70 dba) occurs on the east and south facades of Tower C (Receptors 2, 4, 15, and 22), which are nearest and most exposed to Lyon Street and Slater Street. Outdoor noise levels are below the ENCG objective noise level of 55 dba. As such, noise control measures or mitigation are not required.

Therefore, upgraded building components will be required. The STC requirements for the windows of the three towers are summarized in Table 4 below for various units on various building facades within the development (see Figures 3-4): TABLE 4: STC REQUIREMENTS Location Facade Retail room window STC Living room window STC Bedroom window STC Tower A (Hotel) North East South Tower B West East North Tower C South East Note: Exterior wall components on these façades require a minimum STC of 45, where a window/wall system is used. Wall assemblies meeting STC 45 would include steel stud walls minimum 92 mm deep filled with batt insulation, exterior dense glass sheeting, and 16 mm gypsum board on the inside.

12 A review of window supplier literature indicates that the specified STC ratings can be achieved by a variety of window systems having a combination of glass thickness and inter-pane spacing. We have not specified any particular window configurations, as there are several manufacturers and various combinations of window components that will offer the necessary sound attenuation rating. However, it is the responsibility of the manufacturer to ensure that the specified window achieves the required STC. This can only be assured by using window configurations that have been certified by laboratory testing. The requirements for STC ratings assume that the remaining components of the building are constructed and installed according to the minimum standards of the Ontario Building Code. The specified STC requirements also apply to swinging and/or sliding patio doors. All specified building components will require review by a qualified acoustical engineer for conformance to the recommendations of this report prior to building permit application. Results of the calculations also indicate that all units in Towers A, B, and C will require air conditioning (or similar mechanical system), which will allow occupants to keep windows closed and maintain a comfortable living environment. In addition to ventilation requirements, it will also be required to include Warning Clauses in all Lease, Purchase and Sale Agreements, as summarized in Section CONCLUSIONS AND RECOMMENDATIONS The results of the current study indicate that roadway traffic is the dominant source of noise impacting the site. Noise levels due to roadway traffic will range between 50 and 70 dba during the daytime period (07:00-23:00) and between 42 and 62 dba during the nighttime period (23:00-07:00). The highest noise level (i.e. 70 dba) occurs along the south and east façades of Tower C. In addition, higher Sound Transmission Class (STC) ratings are required for building components where noise levels exceeded 65 dba, as described in Section 5.2 (See Figures 3-4). Results of the calculations also indicate that all units in Towers A, B, and C will require air conditioning (or similar mechanical system), which will allow occupants to keep windows closed and maintain a comfortable living environment. In addition to ventilation requirements, it will also be required to include Warning Clauses in all Lease, Purchase and Sale Agreements, as summarized 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 roadway traffic Manor Park Management 383 Slater Street / 400 Albert Street, Ottawa: Roadway 9
