INTRODUCTION It is proposed to develop the subject site at 5-9 Folkestone Street, Bowen Hills (Lots 6 to 8 on RP10094) with a multi unit dwelling comprising 8 levels of residential units (Ground (Level 1) to Level 8) and a basement level carpark. Based on the consultant’s site inspection the only potential environmental noise impacts upon the subject site are rail noise from the railway line to the west of the subject site, traffic noise from Abbotsford Road, noise from the commercial premises on the western side of Abbotsford Road and noise from Perry Park (soccer fields, carpark and grandstand) to the north of the subject site. The subject site is within a Transport Noise Corridor, as defined by Brisbane City Council – Queensland Development Code Transport MP 4.4 Noise, Sub-Category 1. In Sub-category 1 the anticipated traffic noise level is 58 – 62 dB(A) LA10,18H and the minimum transport noise reduction required for habitable rooms is 25 dB(A). Noise from vehicle activities and airconditioning units on the subject site could noise impact the adjoining residential uses. To assess rail noise impact upon the subject site and ambient noise levels a 48-hour noise level study was conducted from Monitoring Location A, on the southern (rear) boundary of 5 Folkestone Street, 3 metres in from the western boundary, with the microphone elevated 6 metres. This monitoring location was approximately 120 metres from the closest railway line and 80 metres from the closest commercial premises on the opposite side of Abbotsford Road. This report details the results of this noise level study, road, rail, commercial premises and on-site vehicle movement noise limits, noise level impacts and any required noise control measures.

CRITERIA Measurements and Calculations All noise level measurements were conducted in accordance with the following:

general requirements of the Queensland environmental protection legislation;

Environmental Protection (Noise) Policy 2008;

Noise Measurement Manual, Queensland Government – Environmental Protection Agency, 3rd Edition, March 2000;

Australian Standard AS 1055.1 – 1997, Acoustics – Description and measurement of environmental noise, Part 1 – General procedures;

Australian Standard AS 2702-1984, Acoustics – Methods for the Measurement of Road Traffic Noise (traffic noise).

All traffic noise calculations were performed in accordance with the following:

Calculation of Road Traffic Noise, Department of Transport, Welsh Office, HMSO, 1988; and

Australian Standard AS 3671-1989, Acoustics – Road Traffic Noise Intrusion – Building Siting and Construction.

Noise Limits

Rail Noise - DTMR

In accordance with the Department of Transport and Main Roads (DTMR) Policy Position Statement Development on Land Affected by Environmental Emissions from Transport and Transport Infrastructure Version 2, 10 May 2013 the rail noise limits for residential dwellings are:

building facade ≤ 65 dB(A) LAeq,24H facade corrected and ≤ 87 dB(A) (single event maximum sound pressure level ) facade corrected;

open space and recreation areas ≤ 62 dB(A) LAeq,24H free field and ≤ 84 dB(A) (single event maximum sound pressure level ) free field;

inside habitable rooms, ≤45 dB(A) single event maximum sound pressure level. The single event maximum sound level is the arithmetic average of the 15 highest train passby noise levels.

Road Traffic Noise

For road noise, The Brisbane City Council City Plan 2014, Noise Impact Assessment Planning Scheme Policy, does not stipulate noise limits for internal or external areas. The City Plan Information Package for the Noise Impact Assessment Planning Scheme Policy contains the following criteria in the Noise Methodologies Guideline section: outdoor recreation area noise limit is that the maximum LAeq,1hr should not exceed 60 dB(A) (for

any 1-hour period in the 24 hour day) and the LAeq,24hr should not exceed 55 dB(A);

habitable rooms noise limit is 35 dB(A) LAeq.



Time Varying Noise

Noise from vehicle movements on the subject site and from the commercial premises are time-varying. For this type of noise source, the following extract from the Noise Impact Assessment Planning Scheme Policy should be noted: “... Comparison of like parameters will mostly be applicable to assessment of noise emissions,

in which case, an acceptable environmental outcome using this methodology is achieved when the chosen parameter assessing the impact of the development does not exceed the same parameter describing the ambient noise by more than 3 dB(A). ...”.

This criteria applies to time-varying noise, with the following qualifications:

applies during the daytime and evening; requires the source noise to be adjusted for tonality and impulsiveness, as appropriate; applies as a measured level, not a component level; applies at a distance of at least 3.5 metres from sensitive receptors. For time varying noise during the night-time (10 pm to 7 am), a different noise limit is applicable. In accordance with the Noise Impact Assessment Planning Scheme Policy:

“... Research adopted by the World Health Organisation (WHO), concludes that for short duration variable noise sources the onset of sleep disturbance commences at internal Lmax noise levels of between 45 dB(A) and 50 dB(A).

Accordingly, for these noise sources measured internal average maximum noise levels in area categories: R1-R3 must not regularly exceed 45 dB(A) & R4-R6 must not regularly exceed 50 dB(A). ...” Due to the location of the subject site in a residential area the adopted noise limit is 45 dB(A) LAmax.

Steady State Noise

In accordance with the Brisbane City Council City Plan 2014, for the constant continuous noise of plant, the noise limit criteria is that contained is ‘background + 3 dB(A)’ for the daytime, evening and night-time periods, based on the measured background sound levels. RAIL NOISE - DTMR Measured Noise Levels For the statistical parameters rail noise was assessed (unattended noise logger) from monitoring location A, which would have included other ambient noise sources such as traffic, birds, etc, whilst for maximum rail passby noise this was assessed from the same location from the audio file of the noise logger – post analysed in the office. Monitoring location A was approximately 120 metres from the closest of the railway tracks, with the microphone elevated 6 metres, on the southern boundary of the subject site, 3 metres from the western side boundary (closest boundary to the railway line). Refer Appendix A for details of noise level measurement equipment, equipment settings, calibration, monitoring location and atmospheric conditions and Appendix B for complete details of results of noise level measurements at monitoring location A.



For monitoring location A, in accordance with Appendix B, the following noise levels should be noted: Day 1

LAeq,24h = 49.3 dB(A) Day 2

LAeq,24h = 49.4 dB(A) Average

LAeq,24h = 49.4 dB(A) With respect to the single event maximum rail noise levels for train passbys, Table 1 details the maximum noise levels at monitoring location A, for each 1-hour period. For most of the time, rail noise was inaudible due to separation distance, traffic noise and the barrier effect to the railway line of the commercial buildings on the western side of Abbotsford Road.

All of the above noise level measurements were free-field, measured from 3 metres inside the closest boundary to the railway line of the subject site, on the southern boundary, with the microphone elevated 6 metres. From the above single event maximum rail noise levels the fifteen highest values are 70.7, 66.6, 53.8, 53.6, 53.2, 52.7, 52.5, 52.2, 52.0, 51.8, 51.6, 51.4, 50.9, 50.7 and 50.7 dB(A), average = 54.3 dB(A).



Building Facade Noise Levels At monitoring location A the rail noise levels are:

49.4 + 2.5 (facade correction) = 51.9 dB(A) LAeq,24h; and

54.3 + 2.5 (facade correction) = 56.8 dB(A) single event maximum rail passby noise. Both the LAeq,24H noise limit of 65 dB(A) and the single event maximum rail passby noise limit of 87 dB(A) are easily complied with at monitoring location A, which is as close to the railway line as any part of the proposed residential building, for all floor levels. Private Open Space and Recreation Area Noise Levels From the above measured noise levels at monitoring location A the private external living areas also comply with the noise limits. For external living areas these noise limits are an LAeq,24H of 62 dB(A) and a single event maximum rail passby noise limit of 84 dB(A), both free field. Rail Noise – Internal Areas The noise limits for the internal areas of the residential building are:

≤45 dB(A) single event maximum sound pressure level for habitable rooms. The measured noise level was, at monitoring location A, 56.8 dB(A), facade corrected. Therefore, for the closest portion of the building to the railway line, the RNR value would be:

habitable rooms: 56.8 – 45 = 11.8 dB(A). To calculate the minimum Rw requirements for materials of construction for rail noise, the following formula has been used (adopted from AS 3671-1989, traffic noise):

RNABCB = RNR + 10 logB10B [(SBCB SBfB) x (3 h) x 2TB60B x C] where RNABCB = traffic noise attenuation required for the component RNR = traffic noise reduction SBCB = surface area of the component SBfB = surface area of the floor h = ceiling height TB60B = reverberation time = 0.5 seconds C = number of components. Rw = RNABCB + 6 (approximately).

For the closest rooms to the railway Table 2 details the calculated minimum Rw requirements for the materials of construction. For any Units or rooms of Units not included in Table 2 standard materials of construction, including standard glazing, will provide adequate traffic noise level reduction. Refer Appendix C for details of all of the calculations.

Rw 43 to 46: commercial double-glazed window system, consisting of two separate frames and laminated glass from 6.38 mm to 12.76 mm thick with improved acoustic seals.

With respect to the above Rw values, for the purpose of this report standard materials of construction have been assumed to have the following values:

external wall: 35;

roof/ceiling: 35;

glazing: 24 to 26. Based on the results of the calculated minimum Rw values for the closest units to the railway line (as detailed in Table 2), standard materials of construction throughout this proposed development will provide adequate rail noise level reduction. TRAFFIC NOISE Measured Noise Levels For details of the measurement equipment, equipment settings, calibration, monitoring location and atmospheric conditions, refer Appendix A. Monitoring location A is approximately 65 metres from the centre of traffic on Abbotsford Road, with the microphone elevated 6 metres to minimise the noise level reduction of intervening buildings. Appendix B details all of the results of the noise level measurements. In accordance with Appendix B, the following noise levels should be noted: Day 1

LAeq,24h = 49.3 dB(A)

Highest LAeq,1h for 24-hour period = 55.2 dB(A)

Highest LAeq,1h during the daytime and evening, for determining indoor living area noise levels = 55.2 dB(A)

Highest LAeq,1h during the night-time for determining indoor sleeping area noise levels = 50.3 dB(A).

Day 2

LAeq,24h = 49.4 dB(A)






Average

LAeq,24h = 49.4 dB(A)




All of the above noise level measurements were free-field, measured from 3 metres inside the closest boundary to Abbotsford Road, approximately 65 metres from the centre of traffic and with the microphone elevated 6.0 metres.

Predicted Traffic Noise Level Increase Brisbane City Council City Plan 2014, Noise Impact Assessment Planning Scheme Policy, requires that all traffic noise levels be adjusted for the predicted ultimate volume of traffic. Based on Brisbane City Council estimated current and ultimate traffic volumes and percentage commercial vehicles for Abbotsford Road the increase in traffic volume will cause the following increase in traffic noise from Abbotsford Road:

increase in traffic noise: 0.7 dB(A).

Ultimate Traffic Noise Levels For ultimate traffic volumes, the traffic noise levels at monitoring location A will be:

LAeq,24h = 49.4 + 0.7 = 50.1 dB(A)

LAeq,1h maximum = 54.6 + 0.7 = 55.3 dB(A)

LAeq,1h maximum daytime and evening = 54.6 + 0.7 = 55.3 dB(A)

LAeq,1h maximum night-time = 50.4 + 0.7 = 51.1 dB(A).

Traffic Noise Control - External Living Areas The noise limits for external living areas are:

55 dB(A) LAeq,24h; and

60 dB(A) LA10,1h maximum. These noise limits are complied with at monitoring location A and would equally be complied with at all external living areas of the proposed development, including those closest to Abbotsford Road. Therefore, for all of the external living areas – balconies – no traffic noise control is required.



Traffic Noise Control - Internal Living Areas The noise limits for internal habitable areas is 35 dB(A) LAeq,T. The TNR values, therefore, would be, relative to monitoring location A:

Habitable rooms: 55.3 – 35 = 20.3 dB(A). To determine the minimum requirements for Rw values of materials of construction for the proposed Units, the following formula from Australian Standard AS 3671-1989 was used:

TNAC = TNR + 10 log10 [(SC Sf) x (3 h) x 2T60 x C] where TNAC = traffic noise attenuation required for the component TNR = traffic noise reduction SC = surface area of the component Sf = surface area of the floor h = ceiling height T60 = reverberation time = 0.5 seconds C = number of components. Rw= TNAC + 6 (approximately). For the closest rooms of the proposed residential building to Abbotsford Road Table 1 details the minimum Rw requirements. For any rooms not included in Table 3, standard materials of construction, including standard glazing, will provide adequate traffic noise level reduction. Refer Appendix D for full details of calculations.

o daytime: 53 dB(A); o evening: 51 dB(A); o night: 46 dB(A);

o LA1,T: o daytime: 61 dB(A); o evening: 59 dB(A); o night: 54 dB(A);

o LA10,T: o daytime: 55 dB(A); o evening: 53 dB(A); o night: 49 dB(A);

COMMERCIAL PREMISES The commercial premises on the opposite side (western side) of Abbotsford Road have a potential to noise impact the subject site. These commercial premises include:

shop/showroom with associated warehouse;

motor vehicle second hand dealerships;

office building;

automotive smash repairs;

automotive tyre fitting.



The closest of these commercial premises to the subject site are approximately 80 metres distant and include the office building, automotive smash repairs and automotive tyre fitting. From previous noise level measurements conducted by the consultant, typical commercial premises noise levels would be:

car driving on driveway: 50 dB(A) LA10,adj,T @ 8 m;

car door closing: 52 dB(A) LA10,adj,T @ 30 m;

car engine starting: 52 dB(A) LA10,adj,T @ 30 m;

delivery vehicle: 65 dB(A) LA10,adj,T @ 8 m;

impact wrench: 58 dB(A) LAeq,T @ 26 m;

light hammering: 83 dB(A) LAeq,T @ 5 m;

radio: 70 dB(A) LAeq,T @ 4 m;

compressor: 77 dB(A) LAeq,T @ 4 m;

cassette airconditioning: 70 dB(A) SWL. At the closest part of the subject site the above source noise levels from the commercial premises on the western side of Abbotsford Road would be:

car driving on driveway: 50 dB(A) LA10,adj,T @ 8 m – 20 (distance) = 30 dB(A);

car door closing: 52 dB(A) LA10,adj,T @ 30 m – 9 (distance) = 43 dB(A);

car engine starting: 52 dB(A) LA10,adj,T @ 30 m – 9 (distance) = 43 dB(A);

delivery vehicle: 65 dB(A) LA10,adj,T @ 8 m – 20 (distance) = 45 dB(A);

impact wrench: 58 dB(A) LAeq,T @ 26 m – 10 (distance) – 10 (inside to outside commercial premises via open doorway facing Abbotsford Road) = 38 dB(A);

light hammering: 83 dB(A) LAeq,T @ 5 m – 24 (distance) – 10 (inside to outside commercial premises via open doorway facing Abbotsford Road) = 49 dB(A);

radio: 70 dB(A) LAeq,T @ 4 m – 26 (distance) – 10 (inside to outside commercial premises via open doorway facing Abbotsford Road) = 34 dB(A);

compressor: 77 dB(A) LAeq,T @ 4 m – 26 (distance) – 10 (inside to outside commercial premises via open doorway facing Abbotsford Road) = 41 dB(A);

cassette airconditioning: 70 dB(A) SWL + 10 (assumed to be ten airconditioning units) – 46 (distance) = 34 dB(A).

Whilst the noise of the airconditioning units is steady state, all of the other noise source detailed above are time varying. The combined noise of all of the airconditioning unitd and the compressor would be 41 + 34 = 42 dB(A) (logarithmic addition). The daytime and evening noise limits for the time-varying noise sources is that the adjusted source noise and ambient noise combined should not exceed the ambient noise level alone, for the same parameter, by more than 3 dB(A). Therefore, based on the measured ambient noise levels, the noise limits are:

daytime: 55 dB(A) LA10,T + 3 = 58 dB(A) LA10,adj,T;

evening: 53 dB(A)LA10,T + 3 = 56 dB(A) LA10,adj,T. The time varying noise sources comply with these noise limits. Therefore, for the commercial premises to the west, no additional noise control measures are required for the time varying noise sources.



For the steady state noise sources (airconditioning units) the noise limits are ‘background + 3 dB(A)’ for the different time periods, namely:

daytime (0700 to 1800 hours): 47 + 3 = 50 dB(A);

evening (1800 to 2200 hours): 45 + 3 = 48 dB(A); and

night-time (2200 to 0700 hours): 40 + 3 = 43 dB(A). The noise of the compressor and cassette airconditioning units are steady state and both of these noise sources, individually and combined, comply with the above noise limits for the complete 24-hour day. PERRY PARK SOCCER To the north of the subject site is Perry Park, which is used for soccer training and competition matches. The closest part of Perry Park where there is likely to be a noise source is approximately 70 metres from the subject site, and these noise sources include:

playing soccer – players voices;

referee whistle;

crowd cheering from grandstand;

carpark;

club house airconditioning. From previous noise level measurements conducted by the consultant, typical source noise levels would be:





people laughing, talking: 60 dB(A) LA10,adj,T @ 10 m;

players communicating: 65 dB(A) LA10,adj,T @ 10 m;

crowd cheering, yelling: 70 dB(A) LA10,adj,T @ 10 m;


referee whistle: 68 dB(A) LA10,adj,T @ 8 m;

airconditioning: 75 dB(A) LAeq,T SWL (three roof mounted units). At the closest part of the subject site the above source noise levels from Perry Park would be:

car driving on driveway: 50 dB(A) LA10,adj,T @ 8 m – 19 (distance) = 31 dB(A);

car door closing: 52 dB(A) LA10,adj,T @ 30 m – 7 (distance) = 45 dB(A);

car engine starting: 52 dB(A) LA10,adj,T @ 30 m – 7 (distance) = 45 dB(A);

people laughing, talking: 60 dB(A) LA10,adj,T @ 10 m – 17 (distance) = 43 dB(A);

delivery vehicle: 65 dB(A) LA10,adj,T @ 8 m – 19 (distance) = 46 dB(A);

players communicating: 65 dB(A) LA10,adj,T @ 10 m – 17 (distance) = 48 dB(A);

crowd cheering, yelling: 70 dB(A) LA10,adj,T @ 10 m – 17 (distance) = 53 dB(A);

referee whistle: 68 dB(A) LA10,adj,T @ 8 m – 19 (distance) = 49 dB(A);

airconditioning: 75 dB(A) LAeq,T SWL (three roof mounted units, 100 m distant) – 48 (distance) + 5 (three units) = 32 dB(A).



The daytime and evening noise limits for the time-varying noise sources is that the adjusted source noise and ambient noise combined should not exceed the ambient noise level alone, for the same parameter, by more than 3 dB(A). Therefore, based on the measured ambient noise levels, the noise limits are:


evening: 53 dB(A)LA10,T + 3 = 56 dB(A) LA10,adj,T. The time varying noise sources (all of the above noise sources except the airconditioning units) comply with these noise limits. Therefore, for Perry Park to the north, no additional noise control measures are required for the time varying noise sources. For the steady state noise sources (three roof mounted airconditioning units) the noise limits are ‘background + 3 dB(A)’ for the different time periods, namely:



night-time (2200 to 0700 hours): 40 + 3 = 43 dB(A). The noise of the airconditioning units are steady state and the combined noise level of these noise sources comply with the above noise limits for the complete 24-hour day. ON-SITE NOISE On-site noise potentially impacting adjoining residential uses includes vehicle activities and noise from airconditioning units. Vehicle Activities From previous noise level measurements conducted by the consultant, typical on-site vehicle noise levels would be:




refuse truck: 65 dB(A) LA10,adj,T @ 10 m. The only residential that could be potentially impacted by on-site vehicle activities is the adjoining residence to the immediate west of the subject site, with the potential impact being vehicles on the driveway of the subject site and refuse truck, all at ground level. The noise of vehicle activities on the subject site at the closest adjoining residence to the west (referenced to a receiver at ground level) would be:

car driving on driveway: 50 dB(A) LA10,adj,T @ 8 m + 3 (distance) – 8 (2 m high acoustic barrier) = 45 dB(A).

car door closing: 52 dB(A) LA10,adj,T @ 30 m + 4 (distance) – 8 (2 m high acoustic barrier) = 48 dB(A);

car engine starting: 52 dB(A) LA10,adj,T @ 30 m + 4 (distance) – 8 (2 m high acoustic barrier) = 48 dB(A);

refuse truck: 65 dB(A) LA10,adj,T @ 10 m + 0 (distance) – 8 (2 m high acoustic barrier) = 57 dB(A).

The daytime and evening noise limits for the time-varying noise sources is that the adjusted source noise and ambient noise combined should not exceed the ambient noise level alone, for the same



parameter, by more than 3 dB(A). Therefore, based on the measured ambient noise levels, the noise limits are:


evening: 53 dB(A)LA10,T + 3 = 56 dB(A) LA10,adj,T. The daytime noise limit is complied with by all potential time varying noise sources at the closest adjoining residence to the west, with a 2 metre high acoustic barrier in place. The evening noise limit is also complied with, except for the noise of the refuse truck which exceeds the evening noise limit by 1 dB(A). With respect to this 1 dB(A) evening noise limit exceedance, it should be noted that, subjectively, a change in noise level of 1 to 2 dB(A) is not discernible to the human ear. Therefore a noise limit exceedance of up to 2 dB(A) will sound the same as the noise limit and, therefore, should be deemed to comply with the noise limit. The acoustic barrier on the nominated part of the western side boundary of the subject site must be 2.0 m high relative to existing ground levels. This acoustic barrier must be located as per Figure 7, must be continuous and gap free and have a minimum surface area density of 10 kg/m2. Examples of suitable materials of construction include:

reinforced concrete;

concrete block;

brick;

hebel panel;

sheet metal at least 2 mm thick;

minimum 7.5 mm thick fibrous cement sheet;

earth mound;

lapped timber palings, for example, kiln dried softwood palings at least 15 mm thick and overlapped a minimum 25 mm or at least 19 mm thick and overlapped a minimum 15 mm;

any combination of the above.

Airconditioning Noise from airconditioning units associated with the proposed development have the potential to noise impact the adjoining residences to the west, south and east. If the airconditioning units are located on balconies then the potentially worst impacted adjoining residences are to the south of the subject site, as of the above three sides of the proposed building the southern side has the greatest number of balconies. For residential cassette airconditioning units a typical noise level would be 63 dB(A) SWL. If there was one airconditioning unit per balcony then there would be a total of 18 airconditioning units on the southern side of the proposed building. The combined noise level of these 18 airconditioning units would be, at the closest adjoining residence to the south at an average separation distance of 20 metres:

63 dB(A) SWL – 34 (distance) + 12 (18 airconditioning units) = 41 dB(A) LAeq,T. For the steady state noise sources (airconditioning units) the noise limits are ‘background + 3 dB(A)’ for the different time periods, namely:



night-time (2200 to 0700 hours): 40 + 3 = 43 dB(A). The combined noise of the airconditioning units comply with the above noise limits for the complete 24-hour day. CONCLUSIONS It is proposed to develop the subject site at 5-9 Folkestone Street, Bowen Hills with a multi unit dwelling comprising 8 levels of residential units and a basement level carpark. Based on the consultant’s site inspection the only potential environmental noise impacts upon the subject site are:

rail noise from the railway line to the west of the subject site;

traffic noise from Abbotsford Road;

noise from the commercial premises on the western side of Abbotsford Road; and

noise from Perry Park (soccer fields, carpark and grandstand) to the north of the subject site. Noise from vehicle activities and airconditioning units on the subject site could noise impact the adjoining residential uses. To assess rail and traffic noise impact upon the subject site and ambient noise levels a 48-hour noise level study was conducted from Monitoring Location A, on the southern (rear) boundary of 5 Folkestone Street, 3 metres in from the western boundary, with the microphone elevated 6 metres. This monitoring location was approximately 120 metres from the closest railway line and 80 metres from the closest commercial premises on the opposite side of Abbotsford Road. Based on the results of the 48-hour noise level study and Department of Transport and Main Roads rail noise limit criteria for the facades of residential buildings and private external living areas, these noise limits are complied with. For internal habitable rooms Table 2 details the minimum Rw requirements. Based on the results of the calculated minimum Rw values, standard materials of construction will provide adequate rail noise reduction to all internal areas. For traffic noise the Brisbane City Council noise limits for external living areas complies with the noise limits for all proposed external living areas. Table 3 details the minimum Rw requirements for traffic noise control to habitable rooms. Based on the results of the calculated minimum Rw values, standard materials of construction will provide adequate rail noise reduction to all internal areas.



With respect to the closest commercial premises on the western side of Abbotsford Road, all potential time varying noise sources also comply with the noise limits for the daytime and evening and all potential steady state noise sources comply with the noise limits for the complete 24-hour day. Noise from Perry Park could include carpark activities, soccer play, referees whistle and crowd noise (cheering, yelling, etc). The noise of these activities were calculated to the subject site and, with no further noise control measures in place, comply with the daytime and evening noise limits. For vehicle activities on the subject site, the daytime and evening noise limits are complied with/effectively complied with by all noise sources associated with vehicle activities on the subject site, for the closest adjoining residence, which is to the immediate west of the subject site, provided a 2.0 metre high acoustic barrier is incorporated into this development on part of the western side boundary, located in accordance with Figure 7. This acoustic barrier must be continuous and gap free and have a minimum surface area density of 10 kg/m2. If the proposed residential units are to airconditioned and there is one airconditioning unit located on each balcony, then the southern side of the proposed building would have the greatest number of airconditioning units. The combined noise level of all of these airconditioning units (18 in total) complies with the noise limits for the complete 24-hour day, with no additional noise control measures in place. RECOMMENDATION It is recommended that, from an environmental noise perspective, the proposed residential development be approved, provided the noise control measures detailed in this report are incorporated into this development.
