5 23, 33 & 39 Deerfox Drive Noise Control Feasibility Study 1.0 INTRODUCTION The proposed development at 23, 33, and 39 Deerfox Drive (Subject Site), is located south-west of the Deerfox Drive and Woodroffe Avenue intersection, as shown on Figure 1 Key Plan. The Subject Site is bound to the south by existing residences along Tierney Drive, to the east by existing residences along Woodroofe Avenue, to the north by Deerfox Drive, and to the west by existing residences along Settlers Ridge Way. The Subject Site has an area 2.25 ha, and the proposed subdivision will comprise of 41 single family dwellings. The development will contain a City of Ottawa municipal road allowance, 16.5 metres wide. The proposed site plan is shown on Figure 2 Site Plan. Novatech has been retained by Glenview Homes (Deerfox) Ltd. (Developer) to assess the environmental impact of noise for the Subject Site, the feasibility of mitigation measures, and recommend the appropriate noise attenuation measures to ensure compliance with the City of Ottawa Environmental Noise Control Guidelines, January 2016 (ENCG) and the Ministry of the Environment Environmental Noise Guideline, August 2013 (Provincial Guideline). As per the ENCG, this report is considered a Phase 1 Noise Control Feasibility Study. A Phase 2 Noise Control Detailed Study will be included as part of the supporting documentation submitted in support of the Plan of Subdivision Application. 2.0 NOISE CONTROL CRITERIA AND GUIDELINES 2.1 Sound Level Criteria The City of Ottawa is concerned with noise from aircraft, roads, transitways and railways as expressed in Section of the Official Plan (OP). These policies are supported by the ENCG which is a technical document that outlines the specific sound level criteria, commonly referred to as the Logarithmic Energy Equivalent Continuous Sound Level (L eq). The ENCG has been used as a guideline for this study. This study considers two types of noise sources, which are assessed separately: Surface transportation noise from Deerfox Drive, classified as a Collector on Schedule E, Urban Road Network, in the OP; Aircraft noise as the Subject Site is located in the Airport Vicinity Development Zone as illustrated on Schedule K, Environmental Constraints, in the OP. When considering surface transportation noise, proposed noise-sensitive developments must be evaluated within 100 m from the right-of-way of an existing or proposed arterial, collector, major collector, light rail transit, or bus transitway; 250 m from the right-of-way of an existing or proposed highway or a Secondary Main railway line; and 500 m from the right-of-way of a freeway, 400 series provincial highway, or Principle Main railway line. For the purposes of this study, Deerfox Drive is considered a collector and is within 100 m of the Subject Site, thus requiring analysis. Woodroofe Avenue is considered an arterial but is greater than 100 m from the Subject Site. 1

8 23, 33 & 39 Deerfox Drive Noise Control Feasibility Study For aircraft noise, the City of Ottawa and the Ottawa International Airport Authority have defined the noise contours using the Noise Exposure Forecast (NEF) and Noise Exposure Projection (NEP) methods. The noise contours define the Airport Operating Influence Zone (AOIZ) and Airport Vicinity Development Zone (AVDZ) as illustrated on Schedule K, Environmental Constraints, in the OP. Annex 10 of the OP further details the Noise Exposure Projection (NEP) areas of the Macdonald- Cartier Airport for planning purposes. The mandate of acoustical engineering in respect to land-use planning is typically to analyze, and where required, design an acceptable acoustic environment that complies with the ENCG document to the extent that is both reasonable and practical. The areas which must be assessed for acoustic protection include the Outdoor Living Area (OLA); and the Indoor Living Environment (ILE), for both living/dining area and sleeping quarters. The OLA is defined as part of the outdoor amenity area provided for the quiet enjoyment of the outdoor environment during the day-time period. These amenity areas are typically backyards, gardens, terraces and patios. The ILE is provided for the quiet enjoyment of the living/dining and sleeping quarters within a dwelling, during both the day-time and night-time periods. Surface Transportation Noise The OLA noise target for road surface transportation noise sources is 55 dba. This criterion may be exceeded by an amount not greater than 5 dba, subject to justification and the use of a warning clause. The ILE sets noise target for road surface transportation noise sources at 45 dba (day-time) and 40 dba (night-time), respectively. If this criterion is exceeded, the property may be subject to building component analysis to ensure noise criteria are met and warning clauses. The outdoor and indoor sound level criteria for surface transportation noise are summarized below in Table

Aircraft Noise The OLA noise target for aircraft noise sources is 30 NEF/NEP. The use of a warning clause is required if the Subject Site is within the AVDZ or AOIZ boundary. The ILE sets noise target for aircraft noise sources at 5 NEF/NEP (day-time) and 0 NEF/NEP (night-time), respectively. If this criterion is exceeded, the property may be subject to building component analysis to ensure noise criteria are met and warning clauses. The outdoor and indoor sound level criteria for surface transportation noise are summarized below in Table

10 23, 33 & 39 Deerfox Drive Noise Control Feasibility Study Table 2.2: Outdoor and Indoor Sound Level Criteria for Aircraft Noise Environment Receiver Location and Description Time Period ENCG Equivalent Sound Level Criteria, NEF/NEP Outdoor Outdoor Living Area 24 hour period 30 Indoor Living/ dining, den areas of residences, hospitals, nursing homes, schools, daycare centres, etc. 24 hour period 5 Sleeping quarters 24 hour period Noise Attenuation Requirements When sound levels are predicted to be less than the specified criteria for the day-time and nighttime conditions, no attenuation measures are required by the proponent. As the noise criteria is exceeded, a combination of attenuation measures is recommended by the City of Ottawa to modify the development environment. These attenuation measures may include: Adjusting the site layout to maximize noise insensitive land uses between the noise source and sensitive receptor; Orienting buildings to provide sheltered zones in rear yards; Constructing noise barriers and/or berms; Building component design for acoustic insulation; Installation of a forced air ventilation system with provision for central air conditioning; Warning Clauses within Subdivision Agreement and Agreement of Purchase and Sale of prospective home buyers, all of which will be registered on title. Road noise from Deerfox Drive was found to exceed the allowable 55 dba noise level criteria. Consequently, alternative site layout options were initially considered to reduce and/or eliminate the need for a noise barrier. The best option would consist of fronting Lots 3 to 10, inclusive, towards Deerfox Drive, thus protecting the rear yard amenity area with the building walls and eliminating the noise barrier requirement along the site frontage. However, from a servicing and grading perspective this alternative isn t ideal as there are no receiving sanitary sewers fronting this section of Deerfox Drive and there is also a significant difference in elevation from the existing Deerfox Drive, which is low, to the proposed Street One. In order to tie into the existing elevations Lots 3 to 10 will likely consist of walkout and lookout units. In order to inform the purchasers, warning clauses will reference the specific mitigation measures utilized and state the need to maintain the specified noise mitigation measures. 4

11 23, 33 & 39 Deerfox Drive Noise Control Feasibility Study 3.0 NOISE SOURCES 3.1 Surface Transportation Deerfox Drive Deerfox Drive is classified as a 2-Lane Urban Collector (2-UCU) as per the 2013 Transportation Master Plan (TMP). As outlined in the ENCG (Appendix B, Table B1), this particular roadway class specifies an AADT of 8,000 vpd which should be used for sound level predictions. See markup of the Schedule E, Urban Road Network, highlighting the Subject Site location in Appendix A. Notwithstanding the above, it is important to note that the current AADT along Deerfox Drive is less than 4,000 vpd per the City Traffic Count which has been provided in Appendix B. For the purpose of this study an AADT of 8,000 vpd was utilized. The roadway noise parameters are summarized below in Table 3.1. Table 3.1: Deerfox Drive Traffic and Road Parameters Roadway Parameters Roadway Classification Annual Average Daily Traffic (AADT) Posted Speed Deerfox Drive 2 - Lane Urban Collector 8,000 vehicles/day km/hr. (40km/hr.) Day / Night Split (%) 92 / 8 Medium Trucks (%) 7 Heavy Trucks (%) Aircraft As mentioned in Section 2.1 above, the City of Ottawa and the Ottawa International Airport Authority have defined the noise contours using the Noise Exposure Forecast (NEF) and Noise Exposure Projection (NEP) methods. The AOIZ and AVDZ boundaries coincide with physical features such as roads, creeks, rail lines, and lot lines where possible. The noise contours include noise levels from aircraft flight, take-off, and ground operations to specific urban areas. See markup of the Annex 10, Land Use Constraints Due to Aircraft Noise, highlighting the Subject Site location in Appendix A. 4.0 NOISE LEVEL MODELLING AND PREDICTIONS 4.1 Surface Transportation - Acoustic Modeling For surface transportation sources, noise levels are calculated using the STAMSON computer program, version This program allows us to input variables of a road or railway such as traffic volume, types of vehicles, speed, barrier locations and topography to determine the environmental noise impact at a point of reception. 5

12 Receiver 23, 33 & 39 Deerfox Drive Noise Control Feasibility Study To analyze the noise impact on the Subject Site from the aforementioned surface transportation noise source, two points of reception were implemented at the critical OLAs and two points of reception were implemented at the critical ILEs. The noise control plan for surface transportation noise (Figure NC1) shows the receiver locations. The parameters used in STAMSON to assess the noise impacts at the receiver locations can be found below in Table 4.1. It should be noted that, when practical and when the proposed layout of the Subject Site in relation to the existing and proposed residences permitted, screening was implemented to limit noise exposure from Deerfox Drive. To be conservative, a height of 5.25 meters was used since the builder has various bungalow products that may be constructed. Noise modeling was undertaken for the following environments: OLAs For the purposes of this noise impact assessment, all receivers for the OLA-16 time period are located 3.0 meters from the building façade, 1.5 meters above grade, and aligned with the midpoint of the subject façade as per the ENCG. ILEs For the purposes of this noise impact assessment, all receivers for the ILED-16 time period are located at the plane of window, 1.5 meters above grade, and aligned in closest proximity to the noise source as per the ENCG. All receivers for the ILES-16, and ILES-8 time periods are located at the plane of window, 4.5 meters above grade, and aligned in closest proximity to the noise source as per the ENCG. Table 4.1: Road Segment/ Receiver Parameters Segment Reference Outdoor Living Areas R1 Road Segment - Receiver Angles Shielding - Barrier Angles RØ1 RØ2 BØ1 BØ2 Receiver source distance (m) Shielding - Barrier Parameters Barrier receiver distance (m) Source ground elevation (m) Receiver ground elevation (m) Barrier ground elevation (m) S S R2 S Indoor Living Environments R1 S R2 S Notes: (1) Refer to Figure NC1 for receiver and noise source locations. (2) All receiver angles are the same for both unattenuated and attenuated scenarios. (3) All receiver angles are the same for ILEs (i.e., ILED-16, ILES-16, and ILES-8). (4) Source height = source ground elevation + 1.5m. 6

13 23, 33 & 39 Deerfox Drive Noise Control Feasibility Study (5) Receiver height = receiver ground elevation + 1.5m (for all OLA and ILED-16 time periods); receiver ground elevation + 4.5m (for ILES-16, and ILES-8 time periods). 4.2 Surface Transportation - Noise Level Predictions The following Table 4.2 summarizes the predicted sound levels at the receiver locations from the results of the STAMSON environmental noise software calculation. The complete modelling outputs can be found in Appendix B. Table 4.2: OLA Noise Level Summary Receiver Unattenuated L eq (8,000 vpd) OLA-16 Attenuated L eq (8,000 vpd) Noise Barrier Reference OLA-16 R No barrier required R Noise Barrier No m Ht Notes: (1) Refer to Figure NC1 for receiver and noise source locations. As outlined in Table 2.1, the target noise level for the OLA is 55 dba, with a provision of an additional 5 dba tolerance subject to justification and the use of a warning clause. For the established OLAs affected by the surface transportation noise within this proposed development, the day-time noise levels fall below the required OLA noise levels when implementing the attenuated measures where required, and below the maximum tolerable OLA noise levels when left unattenuated (i.e. no noise barrier being implemented). Refer to further discussions in Section 5.1 of this report. Table 4.3: ILE Noise Level Summary Receiver Unattenuated L eq (8,000 vpd) ILED-16 ILES-16 ILES-8 R R Notes: (1) Refer to Figure NC1 for receiver and noise source locations. The target noise levels for the ILE, also outlined in Table 2.1, for both living/dining area and sleeping quarters is 45 dba and 40 dba, respectively. To mitigate these sound levels, additional building component analysis is required to ensure noise criteria are met. Refer to further discussions in Section 5.2 of this report. 4.3 Aircraft Noise Level Predictions The impact of aircraft noise on the local environment was determined using IBANA-CALC, a software package developed by the National Research Council of Canada that calculates indoor noise levels for standard roof, wall, and window construction details for appropriate aircraft noise source spectra. Since the Subject Site is located within the AVDZ limit in close proximity to the 25 7

14 23, 33 & 39 Deerfox Drive Noise Control Feasibility Study NEF/NEP defined noise contour, a value of 25 NEF/NEP will be applied for the purpose of this study. As outlined in Table 2.2, the target noise level for the OLA is 30 NEF/NEP. For the established OLAs affected by the aircraft noise within this proposed development, the noise levels fall below the maximum allowable OLA noise level. Refer to further discussions in Section 5.1 of this report. As per the ENCG, all residential units between 25 NEF/NEP and the AIOZ, regardless of the contour location need to be assessed if not following the prescribed measures to mitigate the impact of aircraft noise in accordance to Part 6. The target noise levels for the ILE, also outlined in Table 2.2, for both living/dining area and sleeping quarters is 5 NEF/NEP and 0 NEF/NEP, respectively. To mitigate these sound levels, additional building component analysis is required to ensure noise criteria are met. Refer to further discussions in Section 5.2 of this report. 5.0 NOISE LEVEL ATTENUATION MEASURES 5.1 Outdoor Proposed Noise Barrier To meet the required OLA noise levels for the surface transportation and the current site layout, a noise barrier would be required at the Subject Site. As shown in the table in Section 4.2 of this report, with a 2.2 m high noise barrier being implemented along Lots 3 to 10 the noise levels at the specified OLAs are below the required 55 dba. Also shown in the table in Section 4.2, when left unattenuated the noise levels at the specified OLAs for Lots 3 to 10 remain below the maximum tolerable OLA noise level of 60 dba. In our opionion, the requiredment of a noise barrier for the Subject Site is avoidable based on the following factors: Deerfox Drive is classified as a 2-Lane Urban Collector (2-UCU) as per the 2013 Transportation Master Plan (TMP). As outlined in the ENCG (Appendix B, Table B1), this particular roadway class specifies an AADT of 8,000 vpd and were used for the sound level predictions. However, the current AADT along Deerfox Drive is less than 4,000 vpd per the City Traffic Count; Since the Subject Site is located within the AVDZ limit of the 25 NEF/NEP defined noise contour (which is equivalent to a noise level of 57 dba), the aircraft noise is considered to be above the required 55 dba. Deerfox Drive is currently not a bus route. As per the ENCG the OLA noise target for road surface transportation noise sources is 55 dba. This criterion may be exceeded by an amount not greater than 5 dba, subject to justification and the use of a warning clause. The unattenuated results of the STAMSON environmental noise software calculation were dba or lower under the maximum tolerable OLA noise level of 60 dba. As per the ENCG acoustic barriers (also called noise walls) help to contain sound but they also separate communities; they interfere with the movement and views of people and wildlife, and they separate neighbourhoods. acoustic barriers also decrease a feeling of safety in neighbourhoods and can be a barrier to community cohesiveness. With the goal 8

15 23, 33 & 39 Deerfox Drive Noise Control Feasibility Study of building liveable communities, acoustic barriers should be avoided under most circumstances. Acoustic barriers should only be used when other noise control measures have been considered and there is no other alternative. 5.2 Indoor Proposed Building Component Assessment When ILE noise levels exceed the day-time or night-time, the exterior shell system of the building envelope must be acoustically assessed to ensure the indoor noise criteria is achieved for both the surface transportation and aircraft noise. Based on the results in Section 4.2 and Section 4.3 of this report, in the proposed development the sound levels at various receiver locations are above both the day-time and night-time allowances. Therefore, additional analysis of the cladding system is warranted. To comply with the ENCG policies, the building envelope will require a minimum Acoustic Insulation Factor (AIF) or Sound Transmission Class (STC) rating to provide the desired indoor noise levels as shown above in Table 2.1 and Table 2.2. Although the surface transportation and aircraft noise will be assessed separately, it is necessary to convert both into a common unit of measurement for the purpose of the building component assessment, and to establish the governing scenario. As such, the 25 NEF/NEP was converted into an equivalent L eq 24hr using the following equation from the IBANA-CALC User s Manual in order to assess the building components. L eq 24hr = NEF/NEP + 32 L eq 24hr = = 57 dba At a minimum, all of the units within the Subject Site will need to have a building envelope capable of providing acceptable noise levels to meet the greater of the noise level predictions within Table 4.3 or the 57 dba for the aircraft noise. Per common industry practice, complete walls and individual wall elements are rated per the STC value. The STC ratings of common residential walls built in conformance with the Ontario Building Code typically exceed an STC rating of 35; and standard good quality double-glazed non-operable windows can have STC ratings ranging from 25 to 40 depending on the manufacturer, components, glazing or air spaces thickness, and seal materials. Generally, common industry practice provides sufficient mitigation to obtain the target noise levels for the ILE. Additional details and assessment of the proposed building components will be provided as part of the Phase 2 Noise Control Detailed Study. It is anticipated that Lots 1 to 10 will require further assessment on the proposed building components. 5.3 Provision for Central Air Conditioning To provide indoor isolation and avoid noise intrusion through open windows or doors, the installation of a forced air ventilation system with provisions for central air conditioning may be required. Additional details on which lots may be required to implement provisions for central air conditioning will be provided as part of the Phase 2 Noise Control Detailed Study. It is anticipated that Lots 1 to 10 will require provisions for central air conditioning. 9
