3 Noise Assessment Proposed Guelph Woods Development February 7, 2014 Executive Summary Novus Environmental Inc. (Novus) was retained by 5 Arthur Street Developments, Ontario Inc. to complete an Environmental Noise Feasibility Assessment for their proposed Guelph Woods mixed use commercial and residential development, located in Guelph, Ontario. This report is an update to the Noise Feasibility Study completed in April 2013 by Novus. The update to the analysis is based on the Site Plan included in the Urban Design Master Plan, dated January Changes include redesign of residential towers, inclusion of new townhouse complexes and incorporation of additional outdoor amenity areas/terraces. In addition, this report has been updated to include the current MOE NPC-300 guidelines, which have replaced the MOE LU-131 guidelines used in the previous assessment, which were in effect at that time. Noise impacts were assessed for railway and roadway noise sources, with recommendations presented to meet MOE NPC-300 guidelines. This report outlines the recommended noise control features, based on the current site plan for the proposed development. Requirements for building shell sound isolation have not changed significantly but have been updated to conform to the current plans. The requirement for air conditioning (and associated warning clause) to facilitate closed windows as a means of noise control has been removed, and the provision for air conditioning (and associated warning clause) is currently required for the entire development. Following an update to the current NPC-300 assessment methods for amenity areas/terraces, the previous noise barrier have either a reduced height or been removed. An additional noise barrier is required for a new amenity area/terrace located adjacent to the Guelph Junction Rail line. The vibration control requirements have not changed from the prior report.

6 Noise Assessment Proposed Guelph Woods Development February 7, INTRODUCTION Novus Environmental Inc. (Novus) was retained by 5 Arthur Street Developments, Ontario Inc. to update the Environmental Noise Feasibility Assessment, previously completed by Novus, for their proposed Guelph Woods mixed use commercial and residential development. The proposed development is located at 5 Arthur Street in Guelph, Ontario. This assessment was completed based on the updated Site Plan included in the January 2014 Urban Design Master Plan (UDMP). An assessment of the railway and roadway noise impacts was completed with recommendations presented to meet the Ontario Ministry of the Environment (MOE) Environmental Noise Guideline (NPC-300). The rail vibration impacts were previously assessed and provided in a separate report completed in March 20, The vibration study results were presented as critical set-back distances for mitigation requirements. As the results are generic, the Vibration report has not been updated at this time. 1.1 Nature of the Subject Lands The UDMP concept provides for the establishment of five (5) separate development phases where buildings would be constructed ranging in height from 4 to 14 storeys. The heritage buildings located at the site will be retained and incorporated into the UDMP concept. The proposed development will consist of the following: Phase 1, 2 and 3 Phase 1, 2 and 3 will be located south of the Guelph Junction Rail (GJR) line, and includes three (3) 12-storey residential towers, with 3-storey townhouse complexes located on the east and west ends of each Tower. A total of six (6) townhouse complexes are included. A podium level will connect all three (3) towers, with the potential uses including parking and amenity space. Terraces are anticipated on the rooftops of the towers, Townhouse complexes and the two (2) shared courtyards between the towers. Private balconies are also planned for the residential tower. Phase 4 A 14-storey residential tower + podium will be located on the south edge of the proposed development. The 5-storey podium level is expected to include retail space on the 1 st floor, parking on the remaining 2 nd to 5 th floors, and residential units along the west façade of the 2 nd to 5 th floors. Residential units are proposed for all floors of the tower on all facades. Terraces are anticipated on the rooftop of the podium, along the perimeter of the 9 th floor, and on the 2 nd floor along the west edge of the building Phase 5 A 14-storey residential tower + podium is the only building located on the north end of the site between the Goderich Exeter Railway (GEXR) and the Guelph Junction Rail Line. The podium level is expected to include retail use on the first floor, parking on the remaining 2 nd to 4 th floors, with residential units on the south-east corner from the 2 nd to 4 th floors. Residential units are proposed for all floors of the tower on all facades. Residential units are located at the south-east corner of the podium level on the 2 nd to 4 th floors. Terraces are Novus Environmental 1

7 Noise Assessment Proposed Guelph Woods Development February 7, 2014 located along the south edge of the podium, on the second floor, and on the rooftop of the podium. The existing Historic Buildings have been retained and are located south of the Guelph Junction Line, adjacent to the Speed River. The current land use is not known for these buildings, but has the potential to be used as commercial and residential units. A Site Plan is shown in Figure 1. A 3-D rendering of the proposed development is included in Appendix A. 1.2 Nature of the Surroundings The site is located at 5 Arthur Street in Guelph, Ontario. A context plan is shown in Figure 2. To the north of the site lies railway lands which form part of the GEXR Guelph Subdivision, a segment of Arthur Street, Elizabeth Street, and existing low-density residential lands. The GJR line runs east/west through the site, and divides the development into two (2) segments. To the west of the development lies Wellington Street East/Woolwich Street, Macdonnell Street, existing commercial land, residential land and the Speed River. To the south of the development lies Neeve Street, Cross Street, and existing high and low density residential land uses. To the east lies Arthur Street S, and existing commercial and low-density residential land uses. The land uses surrounding the proposed development include Commercial to the west, and Residential to the north, east and south. 2.0 TRANSPORTATION NOISE SOURCES The following transportation sources have the potential to produce substantial noise levels at the development: GEXR Guelph Subdivision rail corridor; GJR line separating the development; Wellington Street East/Woolwich St; Macdonnell Street; Arthur Street S; Elizabeth Street; Cross Street; and Neeve Street. The level of noise from these sources has been predicted, and this information has been used to identify façade, ventilation and warning clause requirements. Novus Environmental 2

8 Noise Assessment Proposed Guelph Woods Development February 7, TRANSPORTATION NOISE CRITERIA 3.1 Surface Transportation Noise Criteria Ministry of the Environment Publication NPC-300 Noise Sensitive Developments Ministry of the Environment (MOE) Publication NPC-300 provides sound level criteria for noise sensitive developments. The applicable portions of NPC-300 are Part C Land Use Planning and the associated definitions outlined in Part A Background. Table 1 to Table 4 below summarize applicable surface transportation (road and rail) criteria limits. Location Specific Criteria Table 1 summarizes criteria in terms of energy equivalent sound exposure (Leq) levels for specific noise-sensitive locations. Both outdoor and indoor locations are identified, with the focus of outdoor areas being amenity spaces. Indoor criteria vary with sensitivity of the space. As a result, sleep areas have more stringent criteria than Living / Dining room space. Table 1: MOE Publication NPC-300 Sound Level Criteria for Road and Rail Noise Type of Space Time Period Energy Equivalent Sound Exposure Assessment Level Leq (dba) Location Road Rail [1] Outdoor Living Area (OLA) Daytime ( h) Outdoors [2] Living / Dining Room [3] Daytime ( h) Indoors [4] Night time ( h) Indoors [4] Sleeping Quarters Daytime ( h) Indoors [4] Night time ( h) Indoors [4] Notes: 1) Whistle noise is excluded for OLA noise assessments, and included for Living / Dining Room and Sleeping Quarter assessments. 2) Road and Rail noise impacts are to be combined for assessment of OLA impacts. 3) Residence area Dens, Hospitals, Nursing Homes, Schools, Daycares are also included. During the nighttimeperiod, Schools and Daycares are excluded. 4) An assessment of indoor noise levels is required only if the criteria in Table 3 are exceeded. Novus Environmental 3

9 Noise Assessment Proposed Guelph Woods Development February 7, 2014 Ventilation and Warning Clauses Table 2 summarizes requirements for ventilation where windows potentially would have to remain closed as a means of noise control. Despite implementation of ventilation measures where required, warning clauses advising future occupants of the potential exceedence of the Table 1 guideline limits are still required as some occupants may choose not to use the ventilation means provided, This also applies to the OLA where an excess of up to 5 dba over the 55 dba OLA limit is often acceptable to many, particularly in the context of an urban environment. Table 2: MOE Publication NPC-300 Ventilation and Warning Clause Requirements Assessment Location Outdoor Living Area Plane of Window Time Period Daytime ( h) Daytime ( h) Night time ( h) Energy Equivalent Sound Exposure Level Leq (dba) Road Rail [1] Ventilation and Warning Claus Requirements [2] 56 to 60 incl.

The resultant sound isolation parameter is required to be combined to determine and overall acoustic parameter. In addition to the building component criteria outlined in Table 3, NPC-300 also includes a façade construction requirement for Rail Noise only, outlined in Table 4. The façade construction requirements are necessary only if the development is located in the first row of dwellings. Table 4: MOE Publication NPC-300 Rail Noise Façade Requirements Assessment Location Plane of Bedroom Window Distance to Railway Less than 100 m Greater than 100 m [1] {2} Leq 24hr (dba) Notes: [1] 1) Assessed for developments located within the first row of dwellings. 2) Including whistle noise. Noise Control Requirement < 60 No additional requirement > 60 Brick Veneer or Acoustic Equivalent Required < 60 No additional requirement > 60 No additional requirement In summary, Roadway noise impacts were predicted at the plane-of-window for the proposed development. Providing the plane-of-window sound levels exceed the daytime and night-time sound levels indicated in Table 3, consideration of building façade construction and components is required to meet the indoor sound level criteria outlined in Table 1. In addition, the ventilation requirements and warning clauses as outlined in Table 2, have to be considered with specific requirements determined by the plane-of-window noise levels. As the proposed development includes outdoor amenity spaces, an assessment of OLA impacts was completed and compared to the criteria outlined in Table 1. Novus Environmental 5

11 Noise Assessment Proposed Guelph Woods Development February 7, Canadian National / GO Transit Guidelines CN has published updated noise and vibration guidelines for new residential development located adjacent to their railway corridors. These guidelines have also been adopted by Metrolinx/ GO Transit. The GEXR Guelph Subdivision would be classified as a Principal Main Line. Accordingly, the applicable guideline limits are presented below: Table 5: CN / GO Transit Sound Level Criteria for Rail Noise Type of Space Time Period Equivalent Sound Level (dba) Assessment Location Outdoor Living Area Daytime 55 Outdoors Living / Dining Room All 40 Indoors Sleeping Quarters All 35 Indoors CN and GO also generally require: Safety setback of habitable buildings from the railway rights-of-way to be a minimum of 30 metres in conjunction with a safety berm. The safety berm shall be adjoining and parallel to the railway rights-of-way with returns at the ends, 2.5 metres above grade at the property line. A noise attenuation barrier shall be adjoining and parallel to the railway rights-of-way, having returns at the ends, and a minimum total height of 5.5 metres above top-of-rail. Noise walls if used are located on top of the safety berm and/or engineered crash wall. Noise barriers are to be constructed without openings and must be of a durable material weighing not less than 20 kg per square metre of surface area. Subject to the review of the noise report, CN / GO Transit may consider other measures recommended by an approved Noise Consultant. Brick veneer or acoustical equivalent on the first row of housing beside the right of-way. Warning clause requirements. The proposed development is currently located in close proximity to the railway rights-of-way. The above CN/ GO requirements have been reviewed with the respective authorities, and were negotiated separately. Novus Environmental 6

12 Noise Assessment Proposed Guelph Woods Development February 7, TRAFFIC DATA AND FUTURE PROJECTIONS 4.1 Rail Traffic Data Rail traffic data for the GEXR Guelph Subdivision was obtained from Rail America Company Limited (Rail America) and from Metrolinx/ GO Transit. The Freight, VIA and GO rail data received is for a segment of the GEXR Guelph Subdivision further west along the rail line. Based on correspondence from Rail America and Metrolinx/GO Transit, the data received is considered applicable for this segment of track. The GEXR traffic data for Freight and VIA trains was provided as current volumes. A default growth rate of 2.5% was used to forecast the 10-yr future rail traffic volumes. The GO Train traffic data were provided as future projected volumes. The GJR rail data was provided by the City of Guelph, based on existing activity. As indicated by the City of Guelph, the applicable future 10-yr rail traffic volume is projected to double from current volumes. The rail traffic data used in the assessment is summarized below. Table 6: Summary of Rail Traffic Data Used in the Transportation Noise Analysis Railway GEXR, Guelph Subdivision Train Type No. of Trains [1] Day Night Typical No. of Locomotives (Power) Typical No. of Cars (Consist) Maximum Speed (km/h) Freight VIA Passenger GO Transit Guelph Junction Freight 8 2 [2] Notes: 1) The No. of Trains for the Guelph Junction takes into account that 1 train is 2 passes (i.e. 8 No. of Trains = 4 trains, with 2 passes each). 2) Per discussion with the City of Guelph, 1 train per year is scheduled on the Guelph Junction during the nighttime period. The forecasted doubling of traffic volumes is considered excessively conservative for both trains to occur in 1 night. Therefore future forecasted volumes assume a second train occurring on a different night of the year. Copies of the Rail Traffic data and calculations are provided in Appendix B. There are no at-grade rail crossings in the vicinity for the GEXR Guelph Subdivision rail line. An atgrade rail crossing for the GJR is located on Arthur Street S. As indicated by the City of Guelph, the Guelph Junction train horns are not typically sounded at this crossing. The tracks are constructed of continuously welded rail throughout along the GEXR Guelph Subdivision. Jointed rails are used for the Guelph Junction line, in which a +3 dba adjustment was applied to the wheel noise within the modelling to address jointed track conditions. Novus Environmental 7

13 Noise Assessment Proposed Guelph Woods Development February 7, 2014 The GEXR Overpass was observed to have increased noise levels during a train pass-by. An adjustment based on the Federal Transit Administration Transit Noise and Vibration Impact Assessment (FTA Guide) of +4 dba for an overpass was applied to the wheel noise for this section of the rail in the noise modelling. Future rail traffic sound levels at the proposed development were predicted using the Cadna/A computer model. Railways were modelled as line sources of sound, with sound emission rates calculated using the STEAM algorithms, the rail traffic noise model of the MOE. These predictions were validated and are equivalent to those made using the MOE s STEAM or STAMSON v5.04 rail traffic noise models. 4.2 Road Traffic Data Road traffic data was provided by Paradigm Transportation Solutions Limited (PTSL). Existing traffic volumes were determined using traffic volume surveys completed in 2012 and A generalized growth rate of 1.5% was provided by PTSL and used for predicting the 10-yr future traffic volumes. A copy of the existing traffic count data is included in Appendix B. An assumed day/night traffic volume split of 90% daytime / 10% night-time was used. Table 6 summarizes the road traffic data used in the analysis. Copies of the traffic volume calculations are included in Appendix B. Table 7: Summary of Road Traffic Data Used in the Transportation Noise Analysis Roadway Link Year 2023 Traffic Levels (AADT) Commercial Traffic Breakdown Truck Percentages [1] (%) Ratio of Medium to Heavy Trucks [2] (Med:Hvy) Vehicle Speed (km/h) Wellington St / Woolwich St 18, :8 50 Macdonnel Street 16, :8 50 Arthur Street S :8 50 Elizabeth Street 10, :8 50 Cross Street :8 50 Neeve Street 2, :8 50 Notes: 1) Truck Percentages were taken from the Turning Movement Counts 2) Ratio of Medium to Heavy Trucks taken from default ORNAMENT values Roadway traffic sound levels were predicted using the Cadna/A computer model, in a similar manner as roadway noise. Road sound emission rates were calculated using ORNAMENT modelling algorithms contained in STAMSON v5.04, the computerized noise model of the MOE. These predictions were validated and are equivalent to those made using the MOE s ORNAMENT or STAMSON v5.04 road traffic noise models. Novus Environmental 8

14 Noise Assessment Proposed Guelph Woods Development February 7, PROJECTED SOUND LEVELS Sound levels were predicted at the façades of the residential buildings within the development, and include the effect of the surrounding topography. The façade maps of the development, showing the ranges of predicted daytime and night-time sound levels, are presented in Figures 3 to 6 for railway impacts (day/night), railway impacts (24-hr), roadway impacts (day/night), and combined roadway and railway impacts (day/night), respectively. A summary of the worst-case sound levels for each building are presented in the following table. Table 8: Phase Summary of Worst-Case Predicted Façade Sound Levels Road and Rail Building Section [1] [2] Roadway Sound Combined Rail and Railway Sound Levels [1] [2] Levels Road Levels L eq Day L eq Night L eq 24h L eq Day L eq Night L eq Day L eq Night (dba) (dba) (dba) (dba) (dba) (dba) (dba) Tower Phase 1 Townhouse (East) Townhouse (West) Tower Phase 2 Townhouse (East) Townhouse (West) Tower Phase 3 Townhouse (East) Townhouse (West) Phase 4 Podium and Tower Phase 5 [3] Podium and Tower Historic Sections 3 and Building [4] Notes: - Daytime values are 16-hr L eq (Day) sound levels in dba.

The sections are labelled as Section 1 (closest to Guelph Junction Railway), then counter-clockwise from Section 1 (Refer Figure 1). Sections 3 and 5 have the potential to be noise sensitive. Novus Environmental 9

15 Noise Assessment Proposed Guelph Woods Development February 7, FAÇADE RECOMMENDATIONS 6.1 In-Room Noise Assessment As indicated in Table 3, for residential uses, construction conforming to the minimum requirements of the Ontario Building Code (OBC) is considered sufficient to control Railway noise impacts when façade sound exposure levels are less than or equal to 60 dba during the daytime and 55 dba during the night-time. Similarly, OBC construction is considered sufficient for roadway noise impacts less than or equal to 65 dba and 60 dba during the daytime and night-time periods, respectively. Since the worst-case roadway impacts were predicted to be below 65 dba during the daytime and 60 dba during the night-time for all buildings, Railway noise was found to drive the upgraded façade requirements. Based on the predicted façade sound levels shown in Figure 3 (railway) and the summary of façade sound exposure levels in Table 8, upgraded façade treatments are required for the following: Phase 5 Building Podium south facades Phase 5 Building Tower all facades Existing Heritage Building north and east facades of Sections 3 and 5 (refer Figure 1). Phase 1 Townhouse complex (East) north façade. Indoor sound levels and required Sound Transmission Classes (STCs) were estimated using the procedures outlined in National Research Council Building Practice Note BPN-56. The results of the facade STC requirements are discussed in the following sections. Detailed floor plans were not available at the time of the assessment. For the analysis, generic bedrooms and living rooms have been considered. Living rooms and bedrooms were assumed to have an intermediate level of absorption. Once detailed floor plans and façade plans become available, the requirements for the glazing should be reviewed by an Acoustical Consultant Phase 5 Residential Tower Façade Recommendations As detailed floor and façade plans were unavailable at the time of this assessment, the North Building façade recommendations were determined based on an assumed window-to-floor area of 80%. Table 9 summarizes the Facade STC requirements for both the podium and tower of the Phase 5 Residential Tower. It should be noted that corner units are likely to require an increase of approximately 3 STC points to account for noise entering the affected space from two (2) exposed sides.

The Phase 5 Building facade requirements range from STC 35 to STC 39 ratings. Depending on the window-to-wall ratio, the window STC requirements will vary. Assuming the window is the primary path for noise to enter the room, the window requirements for an STC 39 facade could range from STC 32 to STC 38 for 20% and 80% window-to-wall areas, respectively. Windows with an STC 38 rating would typically require laminated glass and/or windows with an overall thickness greater than a typical 1-1/8 window. A summary table of typical window types and STC ratings is included in Appendix C Heritage Building Façade Requirements The existing Heritage Building window requirements were determined based on an assumed 35% window-to-floor area, since detailed floor and façade plans were unavailable at the time. This assumes the primary path of entry for noise is the window. The existing Heritage Building was separated into five (5) sections for this assessment. Section 1 is located closest to the Guelph Junction rail line, with Section 2 located adjacent to Section 1 to the south. The remaining sections are labelled Section 3 to 5, continuing counter-clockwise from Section 2 (See Figure 1). At the time of this assessment, the uses for the Heritage Buildings were not known. In the previous assessment, Sections 1 and 2 were assumed to be used as retail space, with Section 4 used as a common amenity space for the residential Sections 3 and 5. These assumed uses have been retained in this assessment. Table 10 summarizes the window requirements for the existing Heritage Building. Novus Environmental 11

All other facades were predicted to have sound levels below the NPC-300 criteria for requiring upgraded building construction Phase 1 Townhouse (East) Façade Requirements Upgraded façade treatments are required for the north façade of the Phase 1 Townhouse (East) complex only. The north façade recommendations were determined based on an assumed window-tofloor area of 80%, since detailed floor and façade plans were unavailable at the time of this assessment. The facade STC requirements for the north façade are summarized below. Table 11: Summary of Facade STC Requirements Phase 1 Townhouse (East) Complex Phase Building Required STC N E S W Phase 1 Townhouse (East) 34 Notes: - Assumes carpeting in living rooms and bedrooms The north facade requires an STC34 rating. Depending on the window-to-wall ratio, the window STC requirements will vary. The window requirements could range from OBC construction to sealed double glazed windows assuming the window is the primary noise path for entering the room. A summary table of typical window types and STC ratings is included in Appendix C. 6.2 Rail Noise Façade Requirements The railway only noise façade requirements outlined in Table 4 were assessed for all buildings located within 100 m of the GEXR Guelph Subdivision and/or the Guelph Junction rail lines. The buildings considered in this assessment include the Phase 5 Building, the existing Heritage Building, the Phase 1 Residential Tower, and the Phase 1 Townhouse (East) Complex. The following is a summary of the façade requirements for rail noise only on these buildings. Novus Environmental 12

18 Noise Assessment Proposed Guelph Woods Development February 7, Phase 5 Residential Tower and Podium Since the North Building is located within 100 m for both the GEXR Guelph Subdivision rail line and the Guelph Junction rail line, all facades have been assessed against the NPC dba L eq -24hr criteria. The south facade of the podium was predicted to exceed the 60 dba criteria, and is therefore required to have a brick veneer or acoustic equivalent. The 60 dba criteria is exceeded on the Tower portion along the North, West and South facades. Therefore, these facades also require a brick veneer or acoustic equivalent building component construction Existing Heritage Building The L eq -24hr values are predicted to exceed the 60 dba criteria for several facades on the existing historic building. However, the construction of the Historic Building currently includes a masonry façade. Therefore, the brick veneer or acoustic equivalent construction requirements are considered to be met Phase 1 Residential Tower The 60 dba L eq -24hr limits are predicted to be met for all facades of the Middle Section, North Tower. Therefore, no additional façade construction is required Phase 1 Townhouse (East) Complex The 60 dba L eq -24hr limits are predicted to be met for all facades of the North Townhouse complex. Therefore, no additional façade construction is required. 6.3 Outdoor Living Area Impacts The outdoor amenity spaces considered in this assessment includes the following: Rooftop terraces on each of the Phase 1, 2 and 3 Residential Towers; Rooftop terraces on top of the Phase 1, 2 and 3 Townhouse Complexes; 2 nd floor terraces for Phase 1 and Phase 3; Interior Courtyards between the Phase 1, 2 and 3 towers; Terraces on the rooftops of the podiums for Phase 4 and Phase 5 2 nd Floor terraces for Phase 4 and Phase 5. The locations of outdoor amenity spaces are shown in Figure 1. Based on the information provided, the individual private terraces are not anticipated to have a measured depth, between the building façade to the terrace edge, of 4 meters or more. Since this Novus Environmental 13

19 Noise Assessment Proposed Guelph Woods Development February 7, 2014 depth does not meet the NPC m minimum depth requirements for an individual terrace, these amenity spaces have not been included in this assessment Predicted OLA Impacts Noise impacts at each of the tower buildings communal amenity areas have been assessed. A summary of the unmitigated OLA impacts for these communal amenity areas are shown in Table 12. Table 12: Summary of Predicted Outdoor Amenity Space Sound Levels - Unmitigated Phase Amenity Area Location Range of Sound Level Impacts L eq Day (dba) 2nd Floor Terrace 57 Phase 1 Tower Rooftop Terrace Townhouse (East) Rooftop Terrace 57 Townhouse (West) Rooftop Terrace 60 Tower Rooftop Terrace Phase 2 Townhouse (East) Rooftop Terrace 55 Townhouse (West) Rooftop Terrace 59 Tower Rooftop Terrace Phase 3 Townhouse (East) Rooftop Terrace 54 Townhouse (West) Rooftop Terrace 59 2nd Floor Terrace 54 Phase 1, 2 and 3 Interior Courtyard Phase 4 Phase 5 Podium Rooftop Terrace nd Floor Terrace 60 Podium Rooftop Terrace nd Floor Terrace The predicted impacts exceed the 60 dba L eq Day upper limit of the OLA criteria range, at the Phase 5 terraces only. An assessment of noise mitigation for these areas is required Recommended OLA Mitigation Two (2) barriers were considered for the Phase 5 Building terraces. Figure 7 shows the locations/orientations of the proposed barriers. A summary of the rooftop terrace barriers and impacts are shown in Table 13, and shown in Figure 8. Novus Environmental 14

Based on the mitigated impacts in Figure 8 and Table 13, the 60 dba sound level limit + warning clause is met, with the proposed barriers. The proposed barriers can be composed of solid parapet walls and glass / plexiglass panels. The panels should be selected so that they have sufficient mass to adequately attenuate the noise (generally a minimum of 20 kg/m 2 face density). The panels and frames should be free of gaps and cracks on the sides and bottom. The system should also be designed to withstand any wind loading. An alternative to installing the above rooftop barriers is to use localized barriers around any specified seating areas within the OLAs. Since the predicted impacts are not considered excessive for the Phase 5 Building terraces, proper orientation of the seating areas and localized shielding would reduce the noise impacts to levels at or below 60 dba. 7.0 Ventilation and Warning Clause Requirements 7.1 Requirement for Central Air Conditioning Central air-conditioning and a warning clause is required for all affected units where the combined railway and roadway traffic noise exceeds 65 dba L eq and 60 dba L eq during the daytime and nighttime periods, respectively. The combined railway and roadway noise impacts are predicted to be at or below 65 dba L eq and 60 dba L eq during the daytime and night-time periods, respectively, for all facades. Therefore, central air-conditioning is not required for the proposed development. Novus Environmental 15

21 Noise Assessment Proposed Guelph Woods Development February 7, Requirement for Forced Air Heating and Provisions for Air Conditioning Where the daytime and night-time sound levels from the combined railway and roadway traffic exceeds 55 dba L eq and 50 dba L eq, respectively, forced air heating with provisions for future installation of central air conditioning, and a Warning Clause, are required. This would apply to the residential units in all phases and all building facades. A Type C Warning Clause is required for these units. Warning Clause details are provided in Appendix D. The warning clauses must be included in all agreements of purchase and sale or lease and all rental agreements. 7.3 Outdoor Living Areas Following the inclusion of the noise barriers, the OLA noise impacts are at or below 60 dba. A warning clause is required for each OLA, since the predicted impacts exceed the 55 dba criteria by the allowable 5 dba, with the exception of the Phase 3 Townhouse (East) rooftop terrace and the Interior Courtyards. An MOE NPC-300 Type B warning clause will be required. Warning Clause details are provided in Appendix D. The warning clauses must be included in all agreements of purchase and sale or lease and all rental agreements. 7.4 CN Railway / GO Metrolinx /GJR The CN Railway and GO Metrolinx requirements for a Principal Main Line indicate a warning clause should be inserted in all development agreements, offers to purchase, and agreements of Purchase and Sale or Lease of each dwelling unit within 300 m of the railway right-of-way. The Warning Clause Details are provided in Appendix D for both CN and GO. In addition, it is recommended a similar warning clause for GJR be included in offers of purchase, and agreements of Purchase and Sale or Lease of each dwelling unit within 300 m of the right-of-way. The Warning Clause Details for GJR are also provided in Appendix D. 8.0 CONCLUSIONS AND RECOMMENDATIONS The potential for noise and vibration impacts on the proposed Guelph Woods development have been assessed. The vibration impacts were assessed and included in a separate report. Based on the results of our studies, the following conclusions have been reached: An assessment of transportation noise impacts has been completed. Based on the results of the assessment, acoustically upgraded windows are required for the Phase 5 Residential Tower and Podium, existing Heritage Building, and the Phase 1 Townhouse (East) complex, as outlined in Section 6.1 A brick veneer or acoustic equivalent is required for several facades on the Phase 5 Residential Tower and Podium, as outlined in Section 6.2. Novus Environmental 16

22 Noise Assessment Proposed Guelph Woods Development February 7, 2014 Noise barriers are required for the roof top terraces of the Phase 5 Podium, as discussed in Section 6.3. Forced air heating with a provision for central air conditioning is required for all units, as discussed in Section 7. Warning clauses are required for the residential units and amenity areas, as outlined in Section 7 and Appendix D. Given the early stage of design and the conservative analysis that has been completed, the acoustical requirements above should be refined by an Acoustical Consultant as part of the future site plan approval application.

47 Kevin Carr From: Sent: To: Subject: Follow Up Flag: Flag Status: Adam Snow August :38 AM Kevin Carr RE: Train Data Request - Waterloo Ave and Gordon St, Guelph Ontario Follow up Flagged Hi Kevin I apologize for the delay in my response. Preliminary midterm (2021 +/-) weekday commuter train volumes at this location are in the order of 8 trains (6 day, 2 night). I note that these numbers are subject to change and may be influenced by passenger demand and funding availability. Trains will be comprised of a single locomotive and up to 12 passenger cars. The maximum passenger train speed in this area is 16 kph (10 mph). I trust that this information meets your needs. Let me know if you need anything else.
