3 ASSESSMENT OF THE TRAFFIC NOISE IMPACTS AT THE PROPOSED HOLIDAY INN DEVELOPMENT 235 KING EDWARD AVENUE CITY OF OTTAWA 1.0 Introduction Hugh Williamson Associates Inc. has been retained by Holiday Inn Express & Suites Ottawa Airport to undertake a traffic noise impact assessment in relation to satisfying the City of Ottawa Environmental Noise Control Guidelines (ENCG) for the proposed Holiday Inn development to be located at 235 King Edward Avenue, at the intersection of King Edward Avenue and St. Patrick Street, in the City of Ottawa. This report describes an assessment of noise impacts from road traffic on King Edward Avenue, St. Patrick Street and Murray St, at the interior and outdoor living areas of the proposed development. The assessment has been carried out in accordance with City of Ottawa Environmental Noise Control Guidelines 1 by Hugh Williamson Associates. The proposed development is located between Murray Street and St. Patrick St on the eastern side of King Edward Avenue, as shown in Figures 1 and 2. The analysis was based on drawings and information that were received electronically from Woodman Architect & Associates Ltd. General Description of the Proposed Development The proposed Holiday Inn comprises of a nine (9) storey building rising to approximately 27 m above grade with the ground floor level housing the main entry lobby and pre-function / reception area, restaurant, meeting area, kitchen and offices. A fitness centre including an exercise room and indoor pool with associated outdoor terrace is provided on the second level, about 60% of the second level is comprised of guest suites. Internal living areas are located on the second to ninth floor levels and comprise of a mix of double, queen, king and accessible king guest suites. The development includes Outdoor Living Area (OLA) as shown in Figures 3, 4 and 6, which are in the form of roof terraces located at the second, third and seventh floor levels. HVAC equipment is to be located in the basement of the building as such noise impacts from this equipment is insignificant. p. 1

4 Site Description The land surrounding the proposed development consists of predominantly residential and commercial land uses. The primary source of environmental noise is vehicular traffic along St. Patrick Street, King Edward Avenue and Murray Street. Internal Living Areas: Ground Floor The internal layout of the ground floor consists of pre-function / reception area, restaurant, meeting room, and offices, located as shown in Figure 3. Second Floor: The internal layout of the second floor consists of guest suites with living / sleeping areas located as shown in Figure 4. Third to Sixth Floors: Floors three to six have identical layouts and consist of guest suites with living / sleeping areas located as shown in Figure 5. Seventh to Ninth Floors: Floors seven to nine have identical layouts and consist of guest suites with living / sleeping areas located as shown in Figure 6. Outdoor Living Areas (OLA s): Second floor: A large roof terrace is to be located at the second floor level on the south west corner of the building which faces King Edward Avenue and Murray Street, see Figure 4. The second floor level roof terrace provides a significant outdoor living area for the guests with an area of approximately 240 m 2. Third floor: A roof terrace is to be located at the third floor level on the south side of the building facing Murray Street, see Figure 5. The third floor level roof terrace is inaccessible to guests, hence, does not qualify as a noise sensitive point of reception as per ENCG criteria. Seventh floor: A roof terrace is to be located at the seventh floor level on the south side of the building with exposures to King Edward Avenue and Murray Street, see Figure 6. The seventh floor level roof terrace is inaccessible to guests, as such, does not qualify as a noise sensitive point of reception as per ENCG criteria. p. 2

5 2.0 Methodology and Assessment Criteria This report has been prepared in accordance with the assessment procedures set out in the City of Ottawa Environmental Noise Control Guidelines 1, ENCG, and MoE guidelines. 2,3 The outdoor and indoor noise criteria, sound level limits, are provided in Appendix 1. These limits are to be met by proposed noise sensitive developments using control measures such as site design, set-backs, noise barriers, acoustical requirements for building components and ventilation requirements. In some circumstances, warning clauses related to noise are required on titles, leases and sale agreements. The noise assessment methodology is summarised as follows: Noise generated by road traffic is predicted using STAMSON 3,4, a traffic noise model developed by the MoE. STAMSON takes into account such factors as distance from the road, height, nature of the intervening buildings and terrain, ground absorption, and noise barriers, if present. Noise from future road traffic is predicted using STAMSON at critical points of reception at the proposed development. Locations to be considered include outdoor living areas (OLA) as well as plane of window locations, where rooms for living or sleeping are provided. Noise levels are predicted as A-weighted equivalent sound levels, L EQ, (i.e. average levels) for various periods such as Day (07:00 to 23:00) and Night (23:00 to 07:00) periods. A-weighting is a frequency correction to sound pressure levels which approximates the response of the human ear and is used extensively for environmental noise assessments. Results are expressed in dba, A-weighted decibels. Based on the predicted sound levels, the specifications for mitigation measures such as noise barriers, building component requirements, ventilation requirements and warning clauses are determined according to criteria established by the City of Ottawa ENCG as described below. The noise criteria for outdoor living areas and indoor living areas are set out in Tables A1.1 and A1.2, Appendix 1. Building component requirements depend on the predicted outdoor noise levels and are set out in Table A1.3, Appendix 1. Where building component requirements need to be designed to achieve specific indoor sound levels, restrictions may apply such as the construction assembly and areas of walls, windows, and doors. The ventilation requirements, outdoor noise control measures and warning clause requirements are dependent on predicted outdoor noise levels and are set out in Tables A1.5 and A1.6, Appendix 1. Warning clauses, when required, are to be placed on title documents, sale agreements, and lease agreements. p. 3

6 3.0 Points of Reception For the evaluation of noise impacts, the critical points of reception, POR 1, POR 2, POR 3, POR 4, POR 5 and POR 6, were chosen which represent the location of worst case noise impacts at the proposed development. These points of reception are listed in Table 1 and shown in Figures 3, 4, 5, 8 and 9. The noise assessment methodology is followed to predict the outdoor sound levels at the critical points of reception. The predicted sound levels at each point of reception are then used to determine what mitigation levels are needed to achieve the complying outdoor and indoor sound levels as set out in Appendix 1. For assessment of indoor sound levels, points of reception, POR 1 to POR 5, were chosen at various locations on the building, being the most exposed to noise from St. Patrick Street, King Edward Avenue and Murray St respectively. Outdoor sound levels were calculated at these worst case locations, with locations being on the ground floor level, POR 1 and POR 2, and on the third floor level, POR 3 to POR 5. Refer to See Table 1 and Figures 3, 4 and 5. Plane of window locations are used as windows represent the least sound proof building component of the exterior partition. For the assessment of outdoor living areas, the location at POR 6 was selected to represent noise impacts at the outdoor living area, as shown in Table 1 and Figure 4. The point of reception at the OLA is located 3 m from the exterior wall in the centre of the roof terrace, 1.5 m above the finished floor level of the terrace. It is noted that 1.5 m is used to represent the location of a person s head when sitting. p. 4

7 4.0 Noise Source Modelling and Data The following road traffic data was used for assessing the traffic noise impacts at each point of reception on the building. The data was taken from the City of Ottawa ENCG which provides ultimate future traffic volume data for various roadways based on roadway class and number of lanes. The traffic data used represents future traffic volumes and correspond to a mature state of development, in the City s Official Plan. 1 St. Patrick Street is assessed as a 2-Lane Urban Arterial (2-UAU) with 15,000 AADT, posted speed limit of 50 km/hr, a 92/8 day/night split with 7% medium trucks and 5% heavy trucks by volume as set out in Table 1.7, City of Ottawa Environmental Noise Control Guidelines. 1 Murray Street is assessed as a 2-Lane Urban Arterial (2-UAU) with 15,000 AADT, posted speed limit of 50 km/hr, a 92/8 day/night split with 7% medium trucks and 5% heavy trucks by volume as set out in Table 1.7, City of Ottawa Environmental Noise Control Guidelines. 1 King Edward Avenue has been assessed as a 6-Lane Urban Arterial-Divided (4-UAD), with 50,000 AADT, with a speed limit of 40 km/hr, 92/8 day/night split with 7% medium trucks and 5% heavy trucks by volume, as set out in Table 1.7, City of Ottawa Environmental Noise Control Guidelines. 1 The proportions of traffic types and times recommended in the ENCG (Day/Night 92/8, medium trucks 7%, heavy trucks 5 %) were used to develop the traffic data for each road segment as shown in Table 2, Appendix 2. The surrounding topography was assumed to be a generally flat, reflective surface. Refer to Table 2: Future Traffic Volumes and Posted Speed Limits, Appendix 2. p. 5

8 5.0 Noise Impact Assessment Based on the future traffic projections and assumptions discussed in the previous section, sound levels were predicted at each of the worst-case points of reception, POR 1 to POR 6, using the MoE STAMSON noise modelling software. The results of predictions are contained in Tables 3 to 5. Samples of the outputs of the STAMSON software are given in Appendix 2. In the following, the implications of the estimated future noise levels in relation to the ENCG criteria as set out in Appendix 1, are discussed. Building Components As indicated in Table A1.3, where outdoor noise levels exceed various thresholds for living rooms and bedrooms, then building components, walls, windows, etc. must be designed to achieve the indoor sound level criteria set out in Table A1.2. As shown in Tables 3, these thresholds are exceeded during the day for the pre-function room (assessed as a reception area) and meeting room on the ground floor (POR 1 and POR 2) and at the guest suites POR 3 to POR 5 assessed at the third level. Note that these locations are the worst case, that is, the part of the building most exposed to road traffic noise. Hence the building components designed to meet the indoor sound level criteria at these locations will be sufficient to ensure compliance at other noise sensitive locations within the building. The indoor sound level criterion is indicated in Table A1.2. Indoor sound levels in the ground floor pre-function room, the ground floor meeting room and the third floor level most exposed guest suite, facing King Edward Avenue, have been estimated using standard acoustical procedures, see IBANA-Calculation output in Appendix 2, which take into account window areas, wall areas, room sizes and room absorption as well as the sound transmission characteristic of the external walls and windows. Refer to Table 6 for predicted indoor sound levels. External walls have been modelled as brick or stone veneer on insulated stud frame construction. Sound transmission characteristics of these components have been estimated based on national Research Council test data as shown in Appendix 2. It is noted that the proposed construction of brick veneer (STC 53) and cast in-situ concrete structural elements (STC 62) will exceed the minimum building component requirements, i.e. perform better. Windows have been modeled as double glazed operable windows (3 mm glass thickness, 13 mm air gap, 6 mm glass thickness) with sound transmission characteristics based on national Research Council test data as shown in Appendix 2. The resulting estimates of indoor sound levels comply with the daytime sound level criteria and nighttime sound level criteria. As such, with the proposed wall and window construction as specified above, indoor sound levels will meet the sound level criteria set out in Table A1.2. p. 6

9 Outdoor Noise Control Measures As shown in Table 4, without mitigation, future outdoor daytime noise levels at the Outdoor Living Area (OLA) Point of Reception, POR 6, will exceed the outdoor noise level criteria of 55 dba, by up to 17.8 dba. As such noise mitigation is recommended as follows: Recommended Noise Mitigation: Roof Terrace at Second Floor Level (OLA): 3 m high noise barrier around all open edges of the roof terrace as shown in Figure 3. Height measured from finished floor level of terrace. Use of a transparent noise barrier to increase light penetration and vision may be appropriate. Noise barriers requirements: must be solid, with no gaps must have a surface density of no less than 20 kg/m 2, or be a commercial noise barrier product designed with sufficient sound transmission loss to act as an effective noise barrier. p. 7

10 Ventilation Requirements & Warning Clauses The predicted plane of window noise levels shown in Table 5, indicate that there is a requirement that the units be fitted with central ducted air-conditioning. The building has been designed with a central air conditioning and heating system, hence, the City ventilation requirements will be satisfied. The predicted sound levels, and the intention to fit the building with central heating and airconditioning indicate that a Warning Clause Type D in Table A1.6 is appropriate according to ENCG. Warning Clause Type D "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 City s and the Ministry of the Environment's noise criteria." This clause should be included in the Agreements of Purchase and Sale, and incorporated into the relevant development agreements which are registered on title of the property. The predicted sound levels at the roof terrace located on the second floor level, POR 6, were greater than 60 dba prior to mitigation. As per Table A1.5, Control measures (barriers) required to reduce the Leq to below 60 dba and as close to 55 dba as technically, economically and administratively feasible. As the resultant predicted sound levels, after mitigation, exceed 55 dba Warning Clause Type B in Table A1.6 is appropriate according to ENCG criteria. Warning Clause Type B "Purchasers/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) (transitway) (rail) (air) traffic may on occasions interfere with some activities of the dwelling occupants as the sound levels exceed the City's and the Ministry of Environment's noise criteria." p. 8

11 6.0 Conclusions and Recommendations A detailed traffic noise impact assessment has been conducted for the proposed 9-storey Holiday Inn development located at, Ontario. The assessment has been carried out according to City of Ottawa Environmental Noise Control Guidelines taking into account future road traffic noise from King Edward Avenue, St. Patrick Street and Murray Street. The assessment has led to the following recommendations and conclusions: 6.1 The proposed building envelope consisting of double glazed windows (minimum 3 mm glass thickness, minimum 13 mm air gap and minimum 6 mm glass thickness) and brick veneer walls with cast in-situ concrete structure will be sufficient in achieving acceptable indoor noise levels. 6.2 Outdoor sound levels exceed the ENCG criteria for ventilation requirements. The development requires the installation of central air-conditioning. 6.3 It is recommended that the Warning Clause Type B and D, taken from the ENCG, be applied. Warning Clause Type B "Purchasers/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) (transitway) (rail) (air) traffic may on occasions interfere with some activities of the dwelling occupants as the sound levels exceed the City's and the Ministry of Environment's noise criteria." Warning Clause Type D "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 City s and the Ministry of the Environment's noise criteria." This clause should be included in the Agreements of Purchase and Sale, and incorporated into the relevant Development Agreements which are registered on title of the property. 6.4 Noise barriers are recommended for the Roof Terrace (Outdoor Living Area) located on the second floor as follows: 3 m high noise barrier around all open edges of the roof terrace as shown in Figure 3. Height measured from finished floor level of terrace. p. 9

12 Use of a transparent noise barrier to increase light penetration and vision may be appropriate. Noise barriers must be solid, with no gaps Noise barriers must have a surface density of no less than 20 kg/m 2, or be a commercial noise barrier product designed with sufficient sound transmission loss to act as an effective noise barrier.
