3 1.0 INTRODUCTION 1.1 The services of this firm were retained by Robinson Park Development Corp. to prepare a Detailed Noise Control Study for the proposed 6-storey apartment building located at 17, 19 & 23 Robinson Avenue within an existing residential neighbourhood in the City of Ottawa. The objective of this Report is to support an application for Site Plan Approval of the proposed development. 1.2 The site is bounded by the following land uses: - to the north by vacant lands. - to the south by residential homes and furthermore at a considerable distance by a Transitway Station (south of Queensway). - to the east by residential homes, and furthermore to the southeast, the City of Ottawa Municipal Yard. - to the west by residential homes. The location of the site is shown in Figure Major features of the development are defined by the Site Plan drawing prepared by M. David Blakely Architect Inc., dated October, 2008, revised on December 13, Figure 2 illustrates the general layout of the proposed development. 1.4 Major noise sources (current and future) impacting the development include: 1. Queensway (transportation source of noise) 2. Lees Avenue (transportation source of noise) 3. Transitway Station (stationary source of noise) 4. City of Ottawa Municipal Yard (stationary source of noise) 1.5 The scope of this report is to define the minimum noise attenuation requirements for the control of outdoor and indoor environmental sound levels. 1

4 2.0 SUMMARY AND RECOMMENDATIONS 2.1 SUMMARY Based on the analysis conducted in this investigation it is concluded that: 1. a) The unattenuated daytime sound level in the Common Outdoor Living Area (COLA) of the proposed apartment building will not exceed the recommended objective sound level. Therefore, outdoor noise control measures are not required. 2. a) The unattenuated sound levels at the outside walls of the proposed apartment building will exceed the recommended objective sound levels. Indoor noise controls are required for all units along with relevant warning clauses. 3. Although the projected sound levels are predicted to be above the sound level criteria outlined in Section 3, it is feasible to control sound levels within the indoor areas of the proposed apartment building to meet the stated criteria. 2.2 RECOMMENDATIONS A summary of the minimum noise attenuation requirements is presented in Table 1. A detailed description is as follows: 1. Air Conditioning All Units All dwelling units within the proposed building shall be equipped with central air conditioning systems with their condensing units to be located in noise insensitive locations. The sound levels of the condensing units shall meet the MOE's maximum Sound Rating number as well as the maximum sound level at the point(s) of reception outlined in publication NPC-216 and other levels specified by the municipality. The following warning clause shall be registered on title and included in all Development Agreements and Offers of Sale and Purchase or Lease of these properties: In order to achieve a suitable indoor noise environment, windows may have to remain closed; therefore this dwelling unit has been equipped with a central air conditioning system. It is also our recommendation that the necessary detailed technical analysis be performed prior to the certification process for Building 2

5 Permit to optimize the required air conditioning unit Sound Rating number (i.e. 7.6 bels or lower, as appropriate) after taking into consideration the specific lot/house design and proposed a/c unit location. Other a/c noise control measures, where required to meet the sound level criteria at the point(s) of reception, shall also be identified and shown on the applicable permit drawings/specifications. The Analysis Section in this study provides additional important details on the application of air conditioners. 2. Warning Clause *1 All Units The following warning clause shall be registered on title and included in all Development Agreements and Offers of Sale and Purchase or Lease of all units within the building: Purchasers/tenants are advised that despite the inclusion of noise control features within the building units, sound levels from increasing road traffic on Queensway and/or Lees Avenue may continue to be of concern, occasionally interfering with some activities of the dwelling occupants as the sound level exceeds the City of Ottawa s and the Ministry of Environment's noise criteria. The following warning clause shall also be registered on title and included in all Development Agreements and Offers of Sale and Purchase or Lease of these properties: Purchasers/tenants are advised that due to the proximity of the City of Ottawa Municipal Yard, sounds from the yard including, but not limited to, that of warning devices may at times be clearly audible and that the yard s operations may take place throughout the day and night. All Units with Balconies The following warning clause shall be registered on title and included in all Development Agreements and Offers of Sale and Purchase or Lease of those units having a balcony: Purchasers/tenants are advised that despite the inclusion of noise control features within this development and within the building units, sound levels from increasing road traffic on Queensway and/or Lees Avenue may continue to be of concern as the levels in the balcony may exceed the Ministry of *1 Reference should be made to Bulletin No , Environmental Warnings/Restrictions, Ontario Ministry of Consumer and Commercial Relations. 3

6 Environment criteria. 3. Implementation Procedures Prior to the issuance of building permits, the Builder's plans with respect to the units requiring noise control measures as referred to earlier shall be certified by an Acoustical Consultant as being in conformance with the recommendations of the Detailed Noise Control Study as approved and/or amended by the authorities having jurisdiction. Prior to their final inspection and release for occupancy, these dwelling units shall be certified by an Acoustical Consultant as being in compliance with the recommendations of the Detailed Noise Control Study. 4

7 3.0 SOUND LEVEL CRITERIA 3.1 SURFACE TRANSPORTATION CRITERIA The surface transportation noise is based on the objective sound levels specified by the City of Ottawa in their Environmental Noise Control Guidelines (ENCG) and by the Ontario Ministry of the Environment (Ref.: Publication LU-131) for different land uses and spaces. The following is summary of the applicable sound level criteria for surface transportation sources: Outdoor Living Areas (OLA) Area & Time Period Individual or Common Outdoor Living Areas (16 hr, 07:00-23:00) L eq (16) Road and Rail (dba) 55 Indoor Areas Type of Space Living/dining areas of residences, hospitals, schools, nursing/retirement homes, day-care centres, etc. (Time period: 16 hr, 07:00-23:00) Sleeping quarters of residences, hospitals, nursing/retirement homes, etc. (Time period: 8 hr, 23:00-07:00) General offices, reception areas, retail stores, etc. (Time period: 16 hr, 07:00-23:00) Living/dining areas of residences, hospitals, nursing/retirement homes, schools, day-care centres, theatres, places of worship, libraries, individual or semiprivate offices, conference rooms, reading rooms, etc. (Time period: 16 hr, 07:00-23:00) L eq (Time Period) (dba) Road Rail Sleeping quarters of hotels/motels (Time period: 8 hr, 23:00-07:00) The criteria for acceptable outdoor and indoor sound levels are based on 5

8 free-field predicted and/or measured sound levels at the applicable receiver locations, thus the effects of sound reflections and reverberant sound fields are not considered. If the sound level is less than or equal to the sound level criteria, no control measures will be required. The outdoor sound levels may exceed the outdoor sound level criterion by up to 5 decibels, provided that it can be demonstrated that it is not technically, economically or administratively feasible to achieve the criterion and that the occupants are informed of a potential disturbance due to the excess noise by means of a warning clause or cautionary note to be registered on title and included in all Development Agreement(s) and Offers of Sale and Purchase or Lease. Central air conditioning is required when the nighttime sound level at the outside wall of the sleeping quarters or bedrooms is equal to or exceeds Leq8hrs. 60 dba or when the daytime sound level at the outside wall of the Living/Dining/ Recreation space is equal to or exceeds Leq16hrs. 65 dba. If the nighttime sound level at the outside wall exceeds Leq8hrs. 50 dba but is less than 60 dba, or if the daytime sound level at the outside wall exceeds 55 dba but is less than Leq16hrs. 65 dba, then forced air heating with provision for future installation of central air conditioning is required. 3.2 CRITERIA FOR STATIONARY NOISE SOURCES The following criteria apply to the impact of Stationary Sources of noise as defined by the City and the MOE to include industrial and commercial facilities. The criteria apply to the impact of Stationary Sources external to the development on the proposed development or to the impact of any proposed Stationary Sources internal to the development on the development itself. The criteria used in this study are based on the guideline publications prepared by the City of Ottawa ENCG and the Ontario Ministry of Environment for planning of noise-sensitive land uses adjacent to sources of noise Noise Assessment Criteria in Land Use Planning-Publication LU-131 October 1997, Noise Assessment Criteria in Land Use Planning: Requirements, Procedures and Implementation, October 1997, and other relevant publications. The predicted and/or measured predictable worst case 1-hour equivalent sound levels (Leq1hr) of the stationary source(s) are normally compared with the higher of the corresponding Leq 1hr of road traffic or the following criteria: 6

9 Outdoor Points of Reception The criteria for outdoor points of reception in any area amenable for use are: Area Time Of Day Sound Level, dba Major population centres or urban areas (MOE Class 1 Area) Areas that combine urban and rural environments) (MOE Class 2 Area Daytime and Evening 07:00-23:00 Daytime 07:00-19:00 Evening 19:00-23:00 Leq1hr 50* Leq1hr 50* Leq1hr 45* * or the minimum hourly background (ambient) sound level Leq1 hr, whichever is higher In the Plane of a Window The outdoor criteria for the plane of a window during the day and evening time periods are: Area Time Of Day Sound Level, dba Major population centres or urban areas (MOE Class 1 Area) Areas that combine urban and rural environments) (MOE Class 2 Area Daytime and Evening 07:00-23:00 Daytime 07:00-19:00 Evening 19:00-23:00 Leq1hr 50* Leq1hr 50* Leq1hr 45* * or the minimum hourly background (ambient) sound level Leq1 hr, whichever is higher The criteria for bedrooms or sleeping quarters during the nighttime period are: Area Time Of Day Sound Level, dba Major population centres or urban areas (MOE Class 1 Area) Areas that combine urban and rural environments (MOE Class 2 Area) Nighttime 23:00-07:00 Nighttime 23:00-07:00 Leq1hr 45* Leq1hr 45* * or the minimum hourly background (ambient) sound level Leq1 hr, whichever is higher 7

10 Impulse Noise For impulsive sounds, the MOE s recommended general criteria is that the source impulse sound level in dbai not exceed the ambient Leq due to road traffic or the minimum exclusion limits of 50 dba from 0700 to 1900 and 45 dba from The MOE s criteria for specific impulsive sounds that occur on frequent basis are in the range of 50 to 70 dbai depending on the nature of the source and the year the source was established. For impulsive sound characterized by impulses which are so infrequent that they cannot normally be measured using the MOE procedures for frequent impulses, the sound level criterion is 100 dbai. In general, for land use planning purposes of new noise-sensitive land uses, the MOE recommends the use of Publication LU-131, while for investigation of noise complaints and the approval of new Stationary Sources of noise the Ministry recommends the use of Publication to NPC-205. The MOE further states that where reference in Publication NPC-205 specifies two date specific criteria, depending on when the operation of the stationary sources commenced, such as 50 dbai or 60 dbai criteria for metalworking operations, the more stringent of the criteria, i.e. db 50 dbai in the example, is applicable for planning purposes. 8

11 4.0 ANALYSIS 4.1 TRANSPORTATION SOURCES OF NOISE The proposed development is located at 17, 19 and 23 Robinson Avenue in the City of Ottawa as shown in Figure 1.

Introduction The stationary sources of interest identified in this study are the municipal yard to the southeast of the proposed development, the Hurdman (bus) Station to the south and the Ottawa Train Station to the east. 9

12 2. Description of the Sources of Stationary Noise Hurdman Station is a relatively large bus connection point with a heavy volume of bus movements and idling, particularly during rush hours. The Ottawa Train Station is served by Via Rail intercity trains, the locomotives of which may idle for periods of time while and in between loading and unloading passengers at the platforms. The City of Ottawa Municipal Yard is located southeast of the site, at 29 Ch. Hurdman Road, approximately 115 to 225 m from the property line. This type of yard typically has spring/summer operations (such as for the parks or transportation departments), but analyses of several similar yards in the past suggests that the winter operation, particularly during snowfall, is the worst-case situation for sound emission generation; therefore the winter operation is assessed here. Figure 3 shows the locations of the subject sources of stationary noise. A body shop is located at the corner of Hurdman Road and Lees Avenue. The garage door faces the opposite direction from that of the proposed development. There is one exhaust stack on top of the body shop, which is at least 70 meters away from the proposed development, and only visible to those portions of façade that face The Queensway (high ambient). This type of commercial operation would presumably be required to be in compliance with sound level limits at existing residences that are much closer than the proposed residential development. Despite this, past experiences with sound studies of such operations indicate that the sound emissions would not significantly increase the total sound level at the proposed development due to the stationary sources, and would be well below the projected ambient sound levels for daytime operation. Therefore, this source is insignificant to this noise study. 3. Point of Reception The point of reception is approximately where the southeast façade of the proposed development would be, at a height of 18.1 meters (top of sixth floor window). The selected point of reception is the most exposed to the significant stationary sources of noise, due to its direction and height. Figure 3 also shows the point of reception. 4. Established Stationary Source Sound Levels The sound emission levels of the equipment at the municipal yard, busses idling and moving at Hurdman Station and locomotives idling at the Ottawa 10

13 Ottawa Train Station were taken from the SS Wilson database of measured sound levels for such typical sources. A storage dome is located in the municipal yard, presumably for the road salt. A front end loader and trucks may be operating for most of a worstcase hour during a snowfall. The frequency, intensity, specific hours and duration of operations are on an as-needed basis, depending on weather. During a major storm, sanding, salting and ploughing could occur around the clock, with trucks and loaders arriving or departing (e.g., to replenish salt loads) at any time. The sound emission levels of the loader and the trucks (moving and idling) were taken from the SS Wilson database of similar equipment. 5. Sound Level Calculations Model A 3-D computer program for multiple point and line sources and multiple receivers developed by SS Wilson Associates was used to calculate the sound levels. The program takes into account: Reference sound levels and reference distances for the equipment working in each area of the subject development, i.e. sound emission levels. The Cartesian co-ordinates (x, y & z) of all sources and receivers. The number of events or occurrences of the noise in a given time period and the time period of each event. Spherical divergence factor. Additional attenuation due to sound barriers; natural or man-made types. Additional attenuation due to ground (as modified by sources/receiver elevations, the presence of intervening barriers and the type of ground). Atmospheric attenuation due to air molecular absorption. Acoustical shielding due to the presence of intervening buildings between a specific source and the receptor. 6. Impact Assessment and Findings The hourly analysis was divided into daytime (7 am to 11 pm) and nighttime (11 pm to 7 am) assessments. The corresponding maximum 11

14 applicable sound level criteria as set by LU-131 are 50 dba (day) and 45 dba (night). If the lowest hourly ambient sound levels (assessed separately within daytime and nighttime periods) at the receptor due to road traffic are higher than these sound levels, the criteria may be shifted to the higher levels since the receptor is already exposed to such sound levels. Hurdman Bus Station and Ottawa Train Station The total numbers of bus movements and busses idling used were based on actual observations of the Hurdman Station activities during a weekday afternoon evening rush hour. The worst-case operation occurs during such rush hour times, when most of the bus activity occurs at Hurdman Station. Based on past experience with bus stations, these times are taken as hours from 7 am to 9 am and from 5 pm to 7 pm, which are all within the daytime period. The busiest hours during the nighttime (5 am to 7 am) are assumed to have approximately 75% of the peak daytime volume; this is also a conservative estimate based on past experience with such bus stations. The Ottawa Train Station is assumed to have two locomotives idling during the daytime and nighttime hours of assessment. Appendix B includes sample calculations of the stationary sources of noise. The predicted overall sound levels at the receptor during the daytime and nighttime are 46 and 45 dba, respectively. This level is acceptable based on the criteria given above. It should be noted that the ambient sound levels at the receptor during the daytime and nighttime are higher than 46 dba; therefore, the sound levels due to the Hurdman Station and Ottawa Train Station will likely not be audible much of the time. Based on the above findings, noise control measures for the studied stationary sources of noise are not required. City of Ottawa Municipal Yard Actual traffic data for Queensway was not available, so the ambient sound level at the receptor due to traffic was estimated. The relevant road and traffic data were obtained from the City of Ottawa Environmental Noise Control Guidelines, May 2006, as described in Section 4.1 in this report. Because ultimate values are given, the traffic was scaled down conservatively, as it is assumed that the current traffic is significantly less than ultimate. The predicted ambient levels are as follows. 12

15 Sixth floor south façade (exposure to Queensway and municipal yard): Leq24hr 72.3 dba. Fourth floor south façade (exposure to Queensway and municipal yard): Leq24hr 71.7 dba. Sixth floor east façade (exposure to municipal yard, but only partial exposure to Queensway): Leq24hr 69.1 dba. Fourth floor east façade (exposure to municipal yard, but only partial exposure to Queensway): Leq24hr 68.0 dba. The hourly traffic variation was estimated by using values along a similar stretch of road on Hwy 174 (the hourly counts relative to the total should be similar even if actual totals are different). According to the estimate of traffic variation, the lowest hourly ambient sound levels will be related to the 24 hour ambient sound level as follows: daytime, -4 dba; night, -12 to -14 dba. This means that the daytime ambient sound level is estimated to the nearest decibel as follows. Sixth floor south façade: 68 dba daytime, 58 dba nighttime. Fourth floor south façade: 68 dba daytime, 58 dba nighttime. Sixth floor east façade: 65 dba daytime, 55 dba nighttime. Fourth floor east façade: 64 dba daytime, 54 dba nighttime. The estimated sound levels at the building façade due to operation of the municipal yard during the worst-case hour in the winter time is predicted to be up to approximately Leq(1hr) 53 dba at the fourth and sixth floors, east and south sides. This could be the case during the relatively infrequent major snow clearing/storm events occurring during the day or night. It should be noted that below the fourth floor of the development, there is a shielding effect from the building on the north side of the municipal yard, and levels due to the municipal yard drop to 45 to 47 dba at the facades of the proposed development. The combination of sound levels due to the Hurdman Bus Station, the Ottawa Train Station, and the Ottawa municipal yard is predicted to be 54 dba at the point of reception. It should also be noted that during a winter storm, with windows closed, there would be insignificant indoor noise impact on the residents of the proposed development. (Note that standard windows typically produce a 13

16 sound reduction of 10 dba when open and at least 20 dba when closed, from outside to inside.) Further, the MOE guidelines exclude infrequent events including activities related to essential public services such as road maintenance and snow removal. It should also be noted that the ambient sound level prediction is based on conservative assumptions because actual traffic data is not available. Taking into account the requirements of the MOE noise guidelines, the conservative estimate for ambient sound levels and the fact that negligible noise impact would result in practice, noise controls are not recommended. Nevertheless, the warning clause regarding the municipal yard specified in Section 2.2 of this report should be issued. 4.3 OUTDOOR NOISE ENVIRONMENT Noise predictions were carried out using STAMSON Version 5.04 (2000), the computerized version of the MOE noise prediction models, ORNAMENT. Overall sound level at the COLA of the proposed apartment building is shown in Table 2. Sample sound level calculations at representative receptor locations are presented in Appendix B. In consideration of the calculations, it is concluded that for all units within the proposed apartment building, the unattenuated daytime sound level in the designated COLA will not exceed the objective level of Leq 55 dba, therefore, outdoor noise control measures are not required. The analysis presented earlier demonstrated that the established sound level in the Outdoor Living Area during the daytime at the higher levels where balconies may exist are likely to exceed the MOE OLA's criteria. Based on the MOE guidelines, the balconies/terraces for the proposed development are not considered as OLA's due to the existence of the following conditions: a) An outdoor living area for common use is provided within the development (communal amenity area). b) The depth of the balcony/terrace is less than 4m. c) Balconies/terraces are located outside the exterior building façade. d) Balconies/terraces are unenclosed. No physical mitigation measures are therefore required and a warning clause registered on title will suffice. 14

17 4.4 INDOOR NOISE ENVIRONMENT The criteria for indoor Leq sound levels are based on projected Leq levels at the outside face of the dwellings with appropriate assumptions for the differences between the outdoor and indoor sound levels. If the outside Leq levels do not exceed the recommended objective sound levels, then the indoor Leq levels will not be exceeded, assuming standard building construction and openable windows. Overall daytime sound levels at the building facades are shown in Table 3. Overall nighttime sound levels at the building facades are shown in Table 4. In consideration of the estimated sound levels and by comparison to the acceptable indoor noise criteria (Section 3) the following is concluded: The daytime/nighttime noise environment at the outside walls of all units within the proposed building will exceed 60 dba. Central air conditioning is therefore required. The calculated Acoustic Insulation Factors (A.I.F.) are summarized in Tables 3 and 4. Since the projected highest Leq (day) sound level will be equal to or lower than 66 dba and/or the projected highest Leq (night) sound level will be equal to or lower than 63 dba we have not calculated the required Acoustic Insulation Factors (AIF) as the levels will not be of concern to warrant the use of special glazing or building components. Therefore, the highest daytime AIF will be equal to or lower than 28 and the highest nighttime AIF will be equal to or lower than 30 assuming 3 components. 4.5 TYPICAL WINDOW/WALL CONSTRUCTION As the detailed architectural plans are not available at this time, we have made certain assumptions based on typical building designs. Since the highest Leq (day) and/or Leq (night) are calculated to be equal to or lower than 66 dba and/or 63 dba respectively, it is expected that standard window glazing, doors and exterior walls meeting the requirements of the Ontario Building Code will be sufficient for this project. The worst case analysis assumes maximum ratios of window area to floor area of 32% and 20% for living/dining room and bedrooms respectively which should not be exceeded in order for this analysis to remain valid. It must be pointed out that there are several factors affecting the final glass selection including: 15

18 1. Size of window. 2. Room dimensions. 3. Floor level and direction room faces. 4. Fixed or openable glass. 5. The number of building components. 6. Type of wall to be used. 7. Projected sound levels outside the window. As the information above are typical examples only, therefore, prior to submission of the building plans for building permit, we recommend that the detailed architectural drawings of the units requiring noise control measures, as referred to earlier, be examined by the Acoustical Consultant in order to advise the design consultant on the specific building components for noise control. 16
