3 364 St. Patrick Street 7 th May 2013 ASSESSMENT OF THE TRAFFIC NOISE IMPACTS AT THE PROPOSED RESIDENTIAL DEVELOPMENT 364 ST. PATRICK STREET CITY OF OTTAWA 1. 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 residential development at 364 St. Patrick Street located 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 traffic noise from King Edward Avenue, St. Patrick Street and Murray St, on the interior and outdoor living areas of the proposed residential development. The assessment has been carried out in accordance with City of Ottawa Environmental Noise Control Guidelines 1 by Hugh Williamson Associates. The residential 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 residential development comprises of a nine (9) storey building rising to approximately 26.8 m above grade with the ground floor level housing the main entry lobby, restaurant with seating area, office, laundry room and fitness centre. Internal living areas are located on the second to ninth floor levels and comprise of a mix of studio and one and two bedroom apartments. The development includes a significant Outdoor Living Area (OLA) as shown in Figures 3, 4 and 6, which is in the form of a Roof Terrace located at the second floor level. A number of smaller common terraces are located at the seventh floor level. A number of units have small individual balconies at various levels. These are located on the north and western facades of the building. HVAC equipment is to be located in the basement of the building as such noise impacts from this equipment is insignificant. Site Description The land surrounding the proposed development consists of predominantly residential land uses. The primary source of environmental noise is vehicular traffic along St. Patrick Street, King Edward Avenue and Murray Street. p. 1

4 364 St. Patrick Street 7 th May 2013 Internal Living Areas: Second Floor: The internal layout of the second floor consists of studio and one bedroom apartments with living and bedrooms located as shown in Figure 4. Third to Sixth Floors: Floors three to six have identical layouts and consist of studio and one bedroom apartments with living and bedrooms as shown in Figure 5. Seventh to Ninth Floors: Floors seven to nine have identical layouts and consist of studio and one bedroom apartments with living and bedrooms. Outdoor Living Areas (OLA s): Second floor: A large roof terrace is to be located at the second floor level on the southern side of the building which faces Murray Street, see Figure 3. The second floor level Roof Terrace provides a significant outdoor living area for the residents with an area of 264 m 2. Small Balconies and Terraces:* Some units have small individual balconies at various levels with areas less than 10 m 2. These lie on the north and western facades of the building. Two Common Terraces are located on the seventh floor level with areas less the 32 m 2. *It is noted that the small balconies and terraces do not meet the minimum area requirements to be assessed as Outdoor Living Areas as per the City of Ottawa Environmental Noise Control Guidelines as such these do not qualify as noise sensitive points of reception for the purposes of this assessment and have not been included in this study. The ENCG state that for residences, the impacts of noise on OLA s are only considered when outdoor amenity areas such as a backyard or balcony exceed minimum areas of 56 m2 for single family dwellings, 46 m2 for semi-detached units and 37 m2 per unit for multiple unit residential buildings. p. 2

5 364 St. Patrick Street 7 th May Methodology and Assessment Criteria This report has been prepared in accordance with the assessment procedures set out in the City 3, 4, 5 of Ottawa ENCG, and the MoE guidelines for Noise Assessment in Land Use Planning The outdoor and indoor noise criteria (sound level limits) are listed in Appendix 1. These criteria 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 6, 7, 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 (OLAs) as well as plane of window locations, where rooms for living/dining or sleeping are located in residences. 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 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

6 364 St. Patrick Street 7 th May Points of Reception For the evaluation of noise impact, 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, 6 and 7. The noise assessment methodology is followed to predict the outdoor sound levels at the various 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 2 to POR6, 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 five worst case locations, with four locations being on the second floor, POR 3 to POR 6, and one location on the sixth floor, POR 2. Refer to See Table 1 and Figures 3, 4, 5, 6 and 7. 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 1 was selected as being the most exposed to traffic noise impacts. See Table 1 and Figures 3, 4 and 6. The point of reception at the OLA is located 3 m from the dwelling unit wall in the centre of the roof terrace, 1.2 m above the finished floor level of the terrace. It is noted that 1.2 m is used to represent the location of a person s head when sitting. p. 4

7 364 St. Patrick Street 7 th May 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

8 364 St. Patrick Street 7 th May 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 living areas on the upper floors at POR 2 to POR 6. 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 for these upper floor living areas must be designed to meet the indoor sound level criteria, 45 dba as indicated in Table 2. Indoor sound levels in the second floor level living / bedroom areas 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 wood 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 or stone veneer on 8 ICF walls 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

9 364 St. Patrick Street 7 th May 2013 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 1, will exceed the outdoor noise level criteria (55 dba), by up to 12.7 dba. As such noise mitigation is recommended as follows: Recommended Noise Mitigation: Roof Terrace at Second Floor Level (OLA): 2.5 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. Potential for Reassessment of Noise Control Measures The above recommended noise control measures are based on the assumption that there is open space between Murray Street and the proposed location of the Roof Terrace located on the second floor level. Future buildings in this open space may provide shielding from Murray Street road traffic noise and lead to less noise impact. If plans for buildings in this space become known prior to construction, then it is recommended that the need for the above noise control measures be reassessed. p. 7

10 364 St. Patrick Street 7 th May 2013 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. p. 8

11 364 St. Patrick Street 7 th May Conclusions and Recommendations A detailed traffic noise impact assessment has been conducted for the proposed 9-storey residential development located at 364 St. Patrick Street, Ottawa. 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 or stone veneer on 8 ICF walls will be sufficient in achieving acceptable indoor noise levels. 6.2 Outdoor sound levels exceed the ENCG criteria for ventilation requirements. The residential development requires the installation of central air-conditioning in all units. 6.3 It is recommended that the Warning Clause of Type D, below, taken from the ENCG, be applied. "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: 2.5 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 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. p. 9

12 364 St. Patrick Street 7 th May The above recommended noise control measures are based on the assumption that there is open space between Murray Street and the proposed location of the Roof Terrace located on the second floor level. Future buildings in this open space may provide shielding from Murray Street road traffic noise and lead to less noise impact. If plans for buildings in this space become known prior to construction, then it is recommended that the need for the above noise control measures be reassessed. Hugh Williamson, Ph.D., P.Eng.

"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." "This dwelling unit has been fitted with a forced air heating system and the ducting etc. was sized to accommodate central airconditioning. 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 as to comply with the noise criteria of MoE Publication NPC-216, Residential Air Conditioning Devices and thus minimize the noise impacts on and in the immediate vicinity of the subject property." "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 Environment's noise criteria." Purchasers/tenants are advised that due to the proximity of the adjacent industry (facility) (utility), sound levels from the industry (facility) (utility) may at times be audible. *Reference: ENCG 1 Table 1.13 and MoE Guidelines 4 p. 34
