2 Proposed Residential/Mixed Use Development Environmental Noise and Vibration Impact Study Page Executive Summary Choice Properties REIT has retained the services of Aercoustics Engineering Limited to prepare a Preliminary Environmental Noise Report for a proposed Senior s Residence at Richmond Road in Ottawa, Ontario. This noise study is intended for the submission of a Zoning By-law Amendment (ZBA). The Site Plan Approval (SPA) submission is expected to include a separate Detailed Environmental Noise Report when more detailed information is available. The purpose of this study is to examine the existing and future noise environment in the development area and evaluate its impact potential on future noise sensitive receptors. This report also investigates the noise control features that are required for the development in order to meet the noise guidelines of the Ontario Ministry of the Environment and Climate Change (MOECC) and to satisfy the requirements of the City of Ottawa. This report considers the MOECC guideline NPC- Stationary and Transportation Sources Approval and Planning (August ). Figure provides a key plan showing the proposed development location. Figure shows the draft site/concept plan of the proposed development, including road traffic noise calculation locations. Figures and show an illustration of the noise prediction model for stationary noise source impact. The noise impact potential of the surrounding land uses on the proposed project has been examined and is further discussed in this document in accordance with the MOECC noise guidelines. The results of this study indicate that upgraded window, wall and door construction is not required for compliance with the MOECC criteria for indoor sound levels, and no acoustic barriers are recommended to address outdoor living areas. Warning Clauses are recommended to advise future residents of any potential noise impacts. It is understood that the proposed senior s residence is located on the same property as the RCSS Kirkwood food store, and that the two facilities will be operated by separate parties. Because of this special case, the NPC- document indicates that the noise impact from the food store may not need to be considered for land-use planning purposes. However, the developer has elected to consider this for reasons discussed in this report. To address the noise impact from existing nearby stationary noise sources, it is recommended that the property be designated an acoustical Class area, as described by Part, Section. of the City of Ottawa s Environmental Noise Control Guidelines (ENCG) and by the MOECC noise guidelines. Sample wording for a specific Class warning clause is included.

4 Proposed Residential/Mixed Use Development Environmental Noise and Vibration Impact Study Page Introduction Choice Properties REIT has retained the services of Aercoustics Engineering Limited (Aercoustics) to prepare a Preliminary Environmental Noise Report for a proposed Senior s Residence in the City of Ottawa, Ontario. The purpose of this study is to examine the existing and future noise environment in the development area and evaluate its impact potential on future noise sensitive receptors. This report also investigates the noise control features that are required for the development in order to meet the noise guidelines of the Ontario Ministry of the Environment and Climate Change (MOECC) and to satisfy the requirements of the City of Ottawa. This report considers the MOECC guideline NPC- Stationary and Transportation Sources Approval and Planning (August ). This noise study is intended for the submission of a Zoning By-law Amendment (ZBA). The Site Plan Approval (SPA) submission is expected to include a separate Detailed Environmental Noise Report when more detailed information is available. Figure provides a key plan showing the proposed development location. Figure shows the draft site/concept plan of the proposed development, including the critical transportation noise receptors. The proposed development consists of two mid-rise buildings, one with storeys of independent living (Building A) and another with storeys of assisted care or supportive living (Building B). In the context of the MOECC noise guidelines, the independent living units are considered residential and the assisted care building is considered a noise sensitive institutional purpose building. There is a total of residential units; this includes units for independent living and for supportive living. A site plan is included in Appendix A. The proposed site is located on the southwest corner of Kirkwood Avenue and Richmond Road in the city of Ottawa. The adjacent land-uses include existing residential to the northeast, east, south, and west and various commercial buildings to the north including the existing Real Canadian Superstore (RCSS Kirkwood). It is understood that the proposed senior s residence is located on the same property as the RCSS Kirkwood food store, and that the two facilities will be operated by separate parties. This report is based on the following information: Context Plan, dated April, and Architectural Plans, dated April,, both prepared by IBI Group Architects;

5 Proposed Residential/Mixed Use Development Environmental Noise and Vibration Impact Study Page RCSS Kirkwood Site Plan dated June, and Mechanical Plans dated May,, both provided by Loblaws. The dominant road traffic sources in the subject study area include Richmond Road, Kirkwood Avenue and Byron Avenue. This site is not affected by aircraft noise, or rail traffic noise or vibration. Guidelines and Criteria. Transportation Noise - Outdoor Living Area (OLA) MOECC Guidelines recommend that equivalent noise levels (Leq-hr) in outdoor living areas should not exceed dba. Predicted noise levels between dba and dba may be acceptable, provided that the future occupants of the buildings are made aware of the potential noise problems through appropriate warning clauses. Noise levels above dba are generally not acceptable. All unenclosed balconies and elevated terraces that are less than m in depth are exempt from meeting the MOECC outdoor noise criteria with regards to transportation noise sources. Should the depth of the future balconies and terraces be greater than m, they will be subject to the MOECC noise level limit of dba.. Transportation Noise - Indoor Living Spaces Indoor noise levels due to road traffic were also examined with respect to the MOECC Guidelines. Bedrooms are required to meet an indoor Leq-hr of dba from road traffic. The required indoor sound level limit for living or dining rooms is an Leq-hr of dba from road traffic. Retail, dining areas or general office spaces should meet the indoor noise level of dba from road traffic. To achieve these levels, the MOECC noise guidelines provide a basis for the type of windows, exterior walls and doors that will be required based on projected outdoor noise levels. It is also an MOECC requirement that a central air conditioning system be installed for dwellings when the nighttime or daytime outdoor transportation noise levels at the façade of the dwelling are above dba and dba, respectively. The provision for the future installation of central air conditioning must be made if the nighttime sound level is greater than dba and less than or equal to dba on the outside face of a bedroom window or the daytime sound level is greater than dba and less than or equal to dba on the outside face of a living/dining room window. This provision involves a ducted heating system sized to accommodate the addition of central air conditioning by the occupant. The required limits as per NPC- are summarized in Table below.

Stationary Noise Sources The noise level limits pertaining to the stationary noise sources under review have been established based on the MOECC publication NPC-. For sound from a stationary source, the sound level limit at a point of reception, expressed in terms of the one-hour equivalent sound level (Leq-hr), is the higher of the applicable exclusion limit value given in Table, or the background sound level for that point of reception.

Sound level limits apply during the nighttime period for the plane of the window of a noise sensitive space. In general, the outdoor points of reception will be protected during the nighttime as a consequence of meeting the sound level limits at the adjacent plane of window of noise sensitive spaces. Note that for Class,, and areas, the plane of window limits apply to a window that is assumed to be open. For Class areas, the plane of window limits apply to a window which is assumed to be closed, with the understanding that central air conditioning is

This distinction does not affect the The above listed sound level limits for an outdoor point of reception define the point of reception in any area in the development that is amenable for use by residents, including balconies. The sound level limits are also applicable for a point of reception location at the centre of the plane of any residential window or an operable window of a bedroom in a noise sensitive institutional purpose building. The sound level limit for noise produced by emergency equipment operating in nonemergency situations, such as testing or maintenance of such equipment, is db greater than the sound level limits otherwise applicable to stationary sources. Noise Level Predictions. Road Noise Calculations The dominant road traffic sources in the subject study area include Richmond Road, Kirkwood Avenue and Byron Avenue. Due to the intervening setback distance and significant shielding by existing buildings, the road traffic noise from Richmond Road was considered to be acoustically insignificant and is not addressed further. Noise level calculations were performed in accordance with the MOECC Guidelines and by the Guidelines of the Ontario Road Noise Analysis Method for Environment and Transportation (ORNAMENT). Sample copies of the traffic noise predictions from MOECC s Road Traffic Noise Prediction Model STAMSON (Version.) are included in Appendix B. The equivalent sound levels (Leq) due to road traffic were calculated at worst case noise sensitive residential and institutional purpose receptors in the proposed development. Calculations were performed for both daytime and nighttime conditions at receiver heights representing ground floor level as well as the top residential storey.. Road Traffic Data The road traffic volume counts and truck percentages are based on traffic data provided by the City of Ottawa Public Works. An annual growth rate of % for years was applied to the provided data. The day/night split was assumed based on similar roads. Copies of the raw road traffic data are included in Appendix B. Predictions of road traffic noise were based on the road traffic data outlined in Table below.

Heavy/Medium Ratio (%).. Posted Speed (km/hr) Right of Way (R.O.W.) (m) *Data was assumed since information was not yet available. Stationary Noise Calculations The potential impact of the surrounding land uses on the proposed project has been examined. As noted above, the adjacent land-uses include existing residential to the northeast, east, south, and west, and an existing commercial buildings to the north. A site visit was conducted on March, during which Aercoustics staff interviewed facility representatives, recorded equipment information, and completed sound measurements. The RCSS Kirkwood food store located to the north of the proposed site represents the primary stationary noise source in the vicinity. It is understood that the proposed senior s residence is located on the same property as the RCSS Kirkwood food store, and that the two facilities will be operated by separate parties. Applicable noise guidelines indicate that the noise impact on a receptor within the same property boundaries of a stationary source should not be considered. Despite this, and because of the separated operation of these two sites, the developer has elected to assess the noise impact of the food store on the proposed dwellings to ensure future residents are not exposed to objectionable noise levels. Also, it is possible that this specific case is not what was intended in the wording of the MOECC noise guidelines. All other stationary noise sources, which include commercial developments on the north side of Richmond Road, have been considered acoustically insignificant due to the setback distance, the nature of the noise sources, and the ambient road traffic noise from Richmond Road. Based on discussions with the facility engineering staff, assumptions for rooftop unit nighttime duty cycles were made. The refrigeration condensers were assumed to operate at a % duty cycle during nighttime hours. The compressor room intake and exhaust fans were assumed to operate at a % duty cycle at all times. A % nighttime duty cycle was assumed for the mechanical HVAC rooftop units. The garbage

9 Proposed Residential/Mixed Use Development Environmental Noise and Vibration Impact Study Page compactors are enclosed within the existing partial loading dock enclosure and were not considered acoustically significant. Based on discussions with the facility management staff, there is a single loading bay which is used for receiving at any given time, with a second loading bay occupied by a storage trailer. Facility staff have advised that no shipping operations occur outside of daytime hours (: to :) as per the City of Ottawa noise by-law -. It is understood that a no engine idling policy for non-refrigerated trucks is enforced on site. At certain times of year such as holiday seasons, the storage trailer is refrigerated to accommodate additional perishable stock, and may operate for hours per day. Therefore, a worst case predictable daytime hour for the trucking activity includes two refrigerated truck deliveries, which could last up to minutes per delivery, alongside a running refrigerated storage trailer. A worst case predictable nighttime hour includes only the refrigerated storage trailer. There is an emergency standby natural gas generator set located on the rooftop, which is tested regularly for maintenance purposes. The noise from this generator is assessed separately from the other stationary noise sources on site and has a sound level limit db less stringent. It is understood that this testing occurs only during daytime hours. The proposed buildings are expected to have minimal impact on the surrounding environment. This should be confirmed at the detailed noise study stage once mechanical and electrical information becomes available such as the locations of underground parking exhaust fans, cooling towers or emergency standby generator equipment. Noise Prediction Results. Transportation Noise Results Table below lists the daytime and nighttime Leq s due to road traffic as predicted at noise sensitive locations within the development, labelled in blue on the site plan in Figure. There are several ground floor patios associated with Building A and B. These were considered to be outdoor living areas (OLA) for which the road traffic noise impact was assessed. The outdoor living area calculation locations are also shown in Figure. Sample calculations are provided in Appendix B.

Description Outdoor Amenity Area; Building A Outdoor Amenity Area; Building B Source Distance (m) Leq (dba) Day Night Kirkwood Avenue -- Byron Avenue -- The noise levels listed in the table above were used to determine the window glazing as well as exterior wall requirements for each designated point of reception. These requirements consist of assumed window and wall to room floor area percentages based on typical residential high-rise construction in Ontario. Glazing requirements should be verified at the detailed noise study stage once floor plans and architectural drawings are finalized.. Stationary Noise Results The proposed site is currently considered an MOECC Class area due to existing road traffic during evening hours associated with the various commercial buildings. Three noise sensitive receptors were identified on the side which represent the worstcase noise impact locations. Receptors R and R on Building A represent the upper floor plane of window and ground level patio, respectively. Receptor R represents the upper floor plane of window on Building B. Noise from the identified stationary noise sources was modelled using Datakustik s noise prediction software CadnaA (Version.). Sample calculations are included in Appendix C. The building evaluation feature of the CadnaA noise prediction software was used to determine the worst case locations on the facades of the proposed residential buildings. The predicted sound level at the worst case patio location and the north faces of Building A and Building B is outlined in Table. The CadnaA noise prediction model with grid lines at a height of. m is shown in Figure.

Noise Control Recommendations. Outdoor Living Areas The road and rail noise level predictions, as listed in Table above, indicate that the future noise levels at the outdoor points of reception that are directly exposed to road traffic are below the applicable limit of dba. The outdoor amenity area (OLA) located adjacent to Building A is predicted to have an unmitigated equivalent sound level of dba. This is above the OLA sound level limit of dba which indicates that a warning clause is required to inform tenants that noise may at times be audible. It is not considered economically, aesthetically or practically feasible to provide mitigation which would reduce the predicted noise impact on these patios to below dba. As outlined in section.. of the Official Plan (), development without noise barriers is a first principle in the design of the City. Furthermore, it is understood that a large area of dedicated parkland is to be provided as part of this development application, which is expected to include areas set back from busy roads which may serve as alternate outdoor amenity areas for the future residents. The majority of this land is expected to have outdoor sound levels below dba due to road traffic. Any elevated outdoor living areas (OLA) such as terraces with a depth greater than m associated with any of the proposed residential buildings should be analyzed in further detail if any are added at a later stage. It is recommended that the client include warning clauses for all the ground floor residential units which advise future owners that noise from road traffic may at times be audible. See sample wording Warning Clauses in Section of this document.

12 Proposed Residential/Mixed Use Development Environmental Noise and Vibration Impact Study Page. Indoor Living Spaces Indoor sound levels have been examined with respect to MOECC Guidelines as summarized in Section of this report. The recommendations discussed below should be verified upon the detailed review of the architectural design of the proposed development. For the proposed buildings, calculations were performed with the noise insulation modelling software IBANA v. for assumed window and wall to floor area percentages. STC window requirements are expected to be met with standard high-rise window glazing (i.e. mm glass / mm air space / mm glass). Table Recommended Window Glazing Location Façade Floor Number Window STC Exterior Wall STC Buildings A & B All All STC OBC* *Exterior wall components meeting the minimum requirements of the Ontario Building Code (OBC) will provide adequate acoustical protection for the future indoor daytime living spaces. The above listed Sound Transmission Class (STC) rating should be reviewed and confirmed once the final suite layouts and architectural drawings are available. The worst case impact of the daytime road traffic is predicted to be dba at a high floor southeast corner room of the proposed Building B. At this noise level, standard window construction for mid-rise buildings meeting the Ontario Building Code (OBC) requirements is predicted to suffice for noise control purposes. Based on the indoor sound level predictions due to road traffic, central air conditioning is not mandatory for all buildings. However, it is understood that central air conditioning is planned for all units, and furthermore, it would be a requirement as a result of Class designation (see Class discussion below). It is recommended that a general warning clause be included in all lease agreements that advise potential buyers that noise from road traffic may be audible at times. See Warning Clause in Section.. Stationary Noise Sources To meet the Class sound level limits, it is predicted that the store would be required to alter its current operational practices and make significant changes to equipment, trucking routes and structure, including completely enclosing or relocating the south loading bay. This level of mitigation is understood to be cost-prohibitive and not feasible. The area surrounding the subject property is well developed and can be considered an urban commercial hub near a busy road (Richmond Road). The ambient noise character of this environment can be described to be dominated by man-made noise.

13 Proposed Residential/Mixed Use Development Environmental Noise and Vibration Impact Study Page Given this, it is suggested that this property be designated an acoustical Class area, as described by Part, Section. of the City of Ottawa s Environmental Noise Control Guidelines (ENCG) and by the MOECC noise guidelines. The acoustical Class designation is a new item implemented in the MOECC s latest noise guidelines, NPC-, which is meant to be a tool for municipalities to use to promote urban intensification near existing noise sources at which the Class sound level limits may not be feasible. The designation is intended for high-density noise sensitive uses such as mid-rise or high-rise buildings, where central air conditioning is provided and where the size of operable windows is relatively small. This site is determined to qualify as a Class candidate for the following reasons: It is intended for development of new noise sensitive land uses that are not yet built; It is in proximity to existing, lawfully established stationary sources; and It is understood not to be generally feasible to develop the proposed site under the Class sound level limits. Furthermore, a Class area must have formal confirmation/designation from a City or Ontario Municipal Board approval or from a Planning Act application. More specifically, the following are examples of instruments provided by the Ministry through which a land may be designated Class : Zoning by-law provision; Official Plan Amendment; or Section agreement under the Planning Act. Mitigation is provided which is predicted to ensure the stationary noise impact on the proposed receptors is within the Class sound level limits. The recommended mitigation is as follows: The use of a seasonal refrigerated trailer at the loading bay area, which has been used to store excess stock during holiday seasons, shall be removed. With the incorporation of the above mitigation, the predicted sound level at the worst case patio location and the north faces of Building A and Building B is outlined in Table below. The mitigated CadnaA noise prediction model with grid lines at a height of. m is shown in Figure.

Sample Class warning clause wording is provided in Section of this document. Conclusions The results of this study indicate that compliance with the MOECC criteria for indoor sound levels can be achieved with regular construction which meets the requirements of the Ontario Building Code. No acoustic barriers are required to protect outdoor amenity areas. With the incorporation of the noise controls and planning authority designations discussed in this report, the sound levels due to stationary noise sources at the sensitive receptors of the proposed development will comply with the noise guidelines of the MOECC. As indicated in the City of Ottawa and MOECC implementation guidelines, where mitigation is required or noise may be a concern, future occupants will be advised through warning clauses. Section of the report provides notes and sample wording of the warning clauses. When detailed plans are available, including more detailed information on mechanical and electrical equipment selections and locations, these should be reviewed by an acoustical consultant to confirm the architectural sound isolation requirements to ensure compliance with the City of Ottawa noise by-laws and MOECC Guidelines.

15 Proposed Residential/Mixed Use Development Environmental Noise and Vibration Impact Study Page Warning Clauses The proposed buildings are planned to be rental properties. As such, there will not be title agreements for the occupants. These warning clauses shall be included in all lease agreements. Further, the warning clauses shall be included in a condition of the site plan agreement, which is to be registered on title. Rental and lease agreements for all units in the proposed residential and institutional noise purpose buildings are recommended to include the following warning clauses: Warning Clause : 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 occasions interfere with some activities of the dwelling occupants as the sound levels exceed the sound level limits of the Municipality and the Ministry of the Environment and Climate Change. Warning Clause : 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 sound level limits of the City of Ottawa and the Ministry of the Environment and Climate Change. Warning Clause : Tenants are advised that the dwelling unit is in proximity to existing commercial lands whose activities may at times be audible. Warning Clause : Tenants are advised that sound levels due to the adjacent RCSS Kirkwood food store are required to comply with sound level limits that are protective of indoor areas and are based on the assumption that windows and exterior doors are closed. This dwelling unit has been supplied with a ventilation/air conditioning system which will allow windows and exterior doors to remain closed.
