6 Noise Control Study Mann Avenue Development (87 Mann Avenue) 2.2 NOISE SOURCES The City of Ottawa Official Plan stipulates that a noise study shall be prepared when a new development is proposed within 100 metres of an arterial, major collector roadway or bus transitway, 250m of a light rail corridor or highway and 500m of a major 400 freeway series. For the purpose of this report the new development will be analyzed as it is within 100m of collector roads and 500m of the 417 Queensway. Within the area of the proposed site, Schedule F, Section 7, Annex 1965 of The City of Ottawa Official Plan, entitled Urban Road Network stipulates: Mann Avenue: An existing undivided collector road with a protected right of way (ROW) width of 20.2m, consisting of one eastbound and one westbound lane with on street parking and a posted speed of 50Km/hr. Chapel Street: An existing undivided collector road with a protected right of way (ROW) width of 24.3m, consisting of one northbound and one southbound lane with on street parking and a posted speed of 50Km/hr. 417 Queensway: Refer to MOE Noise Control Guidelines. No rail or airport noise affects this site. 3.0 CITY OF OTTAWA NOISE CONTROL GUIDELINES 3.1 Sound Level Criteria The City of Ottawa is concerned with noise from aircraft, roads, transitways and railways as expressed in the City of Ottawa Official Plan (May 2003) since it can affect the quality of life of residents. To protect residents from unacceptable levels of noise, the City of Ottawa has specific environmental noise control guidelines, which are based on the technical guidelines and recommendations prepared by the Ontario Ministry of Environment. The City of Ottawa s Environmental Noise Control Guidelines (ENCG), Final Draft 9 May 10, 2006 has been used for the purpose of this report. The quantitative sound level criteria, which require that specific outdoor and indoor living areas of residential developments meet certain energy equivalent sound levels (Leq), are summarized in Table 1 and Table 2, respectively. Compliance with the outdoor sound level criteria will generally ensure compliance with the indoor sound level criteria when normal construction materials are utilized.

These amenity areas are typically backyards, gardens, terraces and patios. Table 2: City of Ottawa Indoor Noise Level Criteria Time Period Daytime (07:00 23:00) Receiver Location Living/Dining Rooms of residential dwelling units, theatres, places of worship, school, individual or semi9private offices, conference rooms, reading rooms, classrooms, etc Noise Level Criteria (Leq) 45 dba Nighttime (23:00 07:00) Sleeping quarters of residential units, hospitals, nursing homes, senior citizen homes, etc 40 dba 3.2 Noise Attenuation Requirements When sound levels are predicted to be less than the specified criteria for the daytime and nighttime conditions, no attenuation measures are required by the proponent. As the noise criteria is exceeded, a combination of attenuation measures are available to modify the development environment. These attenuation measures may include: Construction of a noise barrier wall and/or berm; Installation of a forced air ventilation system with provision for central air conditioning; Installation of central air conditioning; Custom building design, construction and/or acoustic insulation. If noise levels are expected to exceed the applicable sound level criteria, the City of Ottawa recommends a warning clause be registered on title. This warning clause serves to alert potential buyers and/or renters of the possible noise condition and of any limitations that may exist on his/her property. The warning clause would be registered on title and incorporated in the Development Agreement and in the Agreement of Purchase and Sale. Novatech Engineering Consultants Ltd. 3

Type B Purchasers/tenants are advised that despite the inclusion of noise control features in this 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 City s and the Ministry of the Environment s noise criteria. Type C This dwelling unit is fitted with a forced air heating system and the ducting, etc was sized to accommodate a central air conditioning system. Installation of central air conditioning by the occupant will allow windows and exterior doors to remain closed, thereby ensuring that the indoor sound levels are within the City s and the Ministry of Environment s noise criteria. (Note: The location and installation of the outdoor air conditioning device should be done so Novatech Engineering Consultants Ltd. 4

The traffic and roadway parameters used for sound level predictions are shown in Table 4. Table 4: Traffic and Roadway Parameters Mann Avenue Chapel Street 417 Queensway Roadway Classification 29Lane Collector 9 Undivided 29Lane Collector 9 Undivided 69Lane Freeway Annual Average Daily Traffic (AADT) 8000 veh/day 8000 veh/day 18333/Lane Day/Night Split (%) 92/8 92/8 92/8 Medium Trucks (%) Heavy Trucks (%) Posted Speed 50Km/hr 50Km/hr 100Km/hr 4.2 NOISE LEVEL ANALYSIS The noise levels were analyzed using Version 5.03 of the STAMSON computer program issued by the MOE. Shielding from traffic noise generated by the 417 and Chapel St was inputted into STAMPSON in the form of No of house rows and House density. These values can be seen in Appendix A 9 Sound Level Calculations. Grading was required for the software and were obtained from NCC topographic plans shown on the grading plan contained in the back of this report. Receiver locations used in the noise simulations are shown on Figure 3 Receiver Location Plan. A larger scale plan is included in the back of the report. Novatech Engineering Consultants Ltd. 5

11 Noise Control Study Mann Avenue Development (87 Mann Avenue) 4.3 Noise Level Results STAMPSON simulated output noise levels (dba) or total leq (noise level equivalent) from all sources, can be viewed in Appendix A. Chapel St, Mann Ave and the 417 Queensway exceed the allowable noise level criteria, resulting in a required building façade analysis and warning clauses. The predicted noise levels at the selected receiver locations within the development are illustrated in Table 5. Daytime and nighttime noise levels are shown for the plane of window (POW). The receivers for the apartment units were located at the north9east side for the Mann Avenue Building. The balconies do not meet the City of Ottawa OLA criteria (e.g., OLA needs to be a minimum of 4.0m deep per Appendix B59B6 of ENCG). A receiver was placed at the north9east end of said OLA which presents the worst case sound exposure. Table 5: Simulation Results Noise Levels Leq (dba) File Name (R=Receiver) Daytime (POW Living/Dining) Nighttime (POW 9 Bedroom) R1 (Ground Floor) R2 (Third Floor) Implementation The City of Ottawa ENCG requires that noise clauses be applied when noise levels are above 55dBA and wall & window construction be reviewed when noise levels exceed 60 dba. The acoustical insulation factor (AIF) method recognized by the City of Ottawa is used to assess the wall and window requirements. The Acoustic Insulation Factor (AIF) is used as a measure of the reduction of outdoor noise provided by the elements of the outer surface of a building. The difference between the indoor noise criterion and the outdoor noise level establishes the acoustical insulation requirement for the exterior shell. The exterior shell is comprised of primarily two components; windows and walls (patio doors are treated as windows). Novatech Engineering Consultants Ltd. 6

12 Noise Control Study Mann Avenue Development (87 Mann Avenue) Canada Mortgage and Housing (CMHC) Standards 1 require that no component transmit more than 1/N of the total sound power that would give the maximum acceptable noise level inside the room. Thus, in a room with two exterior components, neither should transmit more than one9half of the total allowable sound power. Mathematically, this basic requirement can be expressed as: Required AIF = L eg (Outside) L eg (Inside) + 10 log 10 (N) +2dBA Where, N = Number of components; L = Sound Level expressed on a common decibel scale. The acoustical insulation factor for each of the buildings, day time giving the highest result, is calculated as follows: 87 Mann Avenue; AIF Day9time = 67 dba 45 dba + 10log(2) dba + 2dBA = 27 dba The above value can also be referenced directly from Table 11.2 in Appendix B. Tables from the document entitled Acoustic Insulation Factor: A Rating for the Insulation of Buildings Against Outdoor Noise, produced by the Division of Building Research, National Research Council of Canada, June 1980 (J.D. Quirt) were used to assess the exterior facade against the required AIF. This reference material is included in Appendix B. In order to assess the façade against the required AIF, percentage of window to room area and exterior wall to room area are required. This information was derived from the typical floor plan, which was obtained from the architect and is included in the back of this report. Results are presented in Table 6. Note, the height of windows and walls were extrapolated as typical heights being 1.5 to 2.0m respectively. Table 6: Percentage Window and Wall Area to Room Area Description Number and Type of Components Forming Building Envelope = 2 (Windows and Exterior Walls) Percentage of Window Area to Total Floor Area of Room Percentage of Wall Area to Total Floor Area of Room Values Corner Unit 87 Mann Ave Using the percentage of window area to room area, and the required acoustical insulation factor (AIF), Table 5 in Appendix B was used to identify the various window assembles that would satisfy the required AIF. Similarly, Table 6.3 in Appendix B was used to select the 1 Road and Rail Noise: Effects on Housing, CMHC, Ottawa. Publication NHA #185 1/78, 1978 Novatech Engineering Consultants Ltd. 7
