2.2 Layout and Use description

We understand this development will be a double storey building. The layout is based on the McDonalds MOD_514 design.

Access to the subject site is via Reynolds Road.

Two drive-through Customer Order Device (COD) units are proposed to be located in the drive through, on the western side the building.

An off-loading bay is located between the northern end of the building and car parking bays and will be used for deliveries. Waste collection is from the staff carpark area to the west of the building.

The site plan for the development is shown in Figure 2.

2.3 Noise-sensitive premises nearby

The closest noise-sensitive premises to the proposed development are presented in Table 1 and are identified in the aerial photo in Figure 3.

We note that the residence at 840 Canning Highway will be shielded from noise on the development site by the two storey buildings on 842 Canning Highway therefore this receiver was not considered in this assessment.

3.0 NOISE CRITERIA

External noise emission from building services plant and other noise sources is governed by the Western Australia Environmental Protection (Noise) Regulations 1997 (the Noise Regulations). The Noise Regulations are a “prescribed standard” under the Environmental Protection Act 1986.

Under the Noise Regulations, noise emissions from one premises when assessed at another must comply with a set of noise limits. The noise limits applicable at a receiver are calculated by adding to a base noise limit an influencing factor (IF), which takes into account the land use and number of significant roads in the surrounding area. These noise limits are known as ‘assigned noise levels’ and apply at the receiving premises, of which there are three kinds: noise sensitive premises (e.g. residences, hotels, schools, aged care, etc.), commercial premises (e.g. offices, retail shops, etc.) and industrial premises. The assigned noise levels depend on the type of receiving premises, the time of day and day of the week.

The noise emissions are assessed over an assessment period which is between fifteen minutes and four hours. The assessment period must be appropriate for the assessment of the emission and depends on the type and character of the noise source(s).

The assigned noise levels are defined in terms of statistical A-weighted and Slow-weighted sound pressure levels and are:

LA 10, this is the noise level not to be exceeded for more than 10% of the assessment period.

LA 1, this is the noise level not to be exceeded for more than 1% of the assessment period.

LA max, this is the noise level not to be exceeded at any time.

In addition, the noise emissions must be free of annoying characteristics such as: impulsiveness, modulation and tonality. The elimination of annoying characteristics should be a priority in the design process. In cases when annoying characteristics cannot be eliminated, adjustments to measured or calculated levels are applied. These adjustments are presented in Table 3 below.

Adjustment where noise emission is not music. These adjustments are cumulative to a maximum of 15dB.

3.1 Influencing factor calculation

The relevant zoning map for the area is provided in Appendix B.

The assumptions made to estimate the influencing factor at the receiver at 35 Reynolds Road are presented in Table 4. We note that at the other residences; 34 Reynolds Road, and 842 and 859 Canning Highway, the influencing factor would be similar or slightly greater but we used the most conservative influencing factor for all four residences.

3.3 Specified works (waste collection, car park cleaning, etc.)

Regulation 14A of the Noise Regulations prescribes that noise emissions from specified works such as carpark cleaning, do not have to comply with the assigned noise levels if the works are carried out in accordance with regulation 14A(2):

during daytime hours

o 07:00 to 19:00 Monday to Saturday (excluding public holiday), or

o 09:00 to 19:00 on a Sunday or public holiday

in the quietest reasonable and practicable manner, and

using the quietest equipment reasonably available.

In the case where specified works are to be carried outside daytime hours (class 2 works) and their noise emissions are likely not to comply with Regulation 7, the works also need to be carried out according to a Noise Management Plan which has been approved by the local government authority CEO.

Predicted noise levels from specified works at the development are presented in Section 4.7 and are further discussed in Section 5.3.4.

4.0 NOISE MODEL

MDA has used a 3D acoustic computer model (Soundplan 7.3) to estimate noise levels from the proposed McDonalds restaurant to the nearest residential dwellings.

The estimates are based on the assumptions described in the following sections.

4.1 Modelling assumptions

The assumptions and noise controls required to achieve compliance are presented in Table 6 and, where applicable, illustrated in Figure 4.

Table 6: Summary of assumptions and noise controls

Item Description

Restaurant operating hours 24 hours per day, 7 days per week


Item Description

Delivery times Restricted to daytime (Mon-Sat 0700 to 1900, Sunday and public holidays 0900 to 1900)

Waste collection times Restricted to daytime (Mon-Sat 0700 to 1900, Sunday and public holidays 0900 to 1900)

If reversing alarms are required, truck to be fitted with broad-band reversing alarms

Carpark cleaning Restricted to daytime (Mon-Sat 0700 to 1900, Sunday and public holidays 0900 to 1900)

Hand-held professional leaf blower only

1 to 2 times a month

Noise walls 2.8 metres high wall spanning the entire width (east-west) of the development on north boundary

2.4m high wall with 0.5m x 0.5m minimum overhang over the closest drive through lane on west boundary

Existing 1.2m to 1.8m high fence from end of 2.4m wall to south boundary.

CODs Localised acoustic canopy. Example shown in Appendix C.

Mechanical services Fans 1 to 6 are to operate on low speed (i.e. low noise) setting during the night-time period.

Building parapets are min. 8.46m above ground. Refer to Appendix E for mechanical plant layout.

4.2 Model setup

The following assumptions in relation to the noise model were made:

Local topography included,

Local ground absorption (‘hard’ for roads and carpark, ‘soft’ for grassed areas),

All sensitive receivers as nominated in Section 2.3,

All existing buildings including any fencing which would provide noise barrier effects,

Proposed McDonalds restaurant double storey building, and

Noise sources and associated sound power levels as nominated in sections below.

Given the distance from source to the closest receivers is much less than 100 metres, we consider the CONCAWE algorithm is not appropriate in this specific case. Instead, the noise levels at all receivers were estimated based on the ISO Standard 9613-2 with the following meteorological conditions: 50% relative humidity and 15oC.

A schematic drawing of the acoustic model is shown in Appendix D.

4.3 Mechanical plant

This development is a based on the McDonalds store MOD_514 series layout and includes the equipment listed in Table 7 and Table 8 below.

The mechanical plant layout and parapet walls location and height used in this assessment are shown in Appendix E.

4.4 Drive through

Use of the drive through consists of a vehicle entering the drive-through, idling while placing an order, moving forward to the collection point, idling while collecting the order and finally, driving away.

This scenario has been represented in the noise model using as series of point sources located along the vehicle paths over the length of the drive through lanes in order to derive the statistical noise levels (LN).

The following vehicle noise data and source heights used are presented in Table 9.

4.5 Customer Ordering Devices (COD)

There will be two CODs overall, one in each drive through lane. MDA have measured noise levels of CODs at several existing McDonalds stores and has determined representative sound power level data for these devices. These are presented in Table 10.

4.6 Deliveries

The noise emissions from deliveries were split into two distinct activities in the noise model: vehicle movements; and delivery.

The sound power data for vehicle movements includes engine noise for various trucks types and represents the pass by noise level.

The data for delivery represents the maximum noise level (Lmax) generated during the delivery from one off events such as impact noises during pallet off-loading or opening/closing of truck doors. We note that during deliveries the truck engine will be switched off.

The sound power levels used in the model for each activity are presented in Table 11 and Table 12.

4.7 Waste collection and carpark cleaning

The noise emissions from waste collections and carpark cleaning activities were assessed independently from other activities on-site.

For waste collections, sound power data for garbage truck movements includes engine noise and represents the pass by noise level while the maximum sound power data represents bin pick-up, waste being emptied into truck and bin placed back on the ground.

The sound power levels used in the model for each activity are presented in Table 13 and Table 14.

5.0 ASSESSMENT

5.1 Representative Assessment Period (RAP)

The assigned noise levels are statistical noise levels occurring over a Representative Assessment Period (RAP) which is technically determined by an inspector or authorised officer. However, based on previous experience of similar projects we considered a RAP of 30 minutes is appropriate for the purpose of assessing the noise emissions from this development.

For a 30 minute RAP period, the assigned levels therefore mean:

The LA 10 is the noise level not to be exceeded for more than 180 seconds in any 30 minutes;

The LA 1 is the noise level not to be exceeded for more than 18 seconds in any 30 minutes; and

The LA max is the noise level not to be exceeded at any time.

5.2 Noise predictions

Noise from all sources on the site must meet the assigned noise levels. Compliance is determined by comparing the predicted noise level to the relevant assigned levels at the nearest affected residential dwellings.

5.2.1 Mechanical plant

The predicted noise levels from mechanical plant are presented in Table 15. For the purposes of this assessment it was assumed all plant operates simultaneously and continuously over extended periods of time. Therefore the applicable criterion for mechanical plant noise is the night-time LA 10.

5.2.2 Drive through

Noise predictions for vehicle movement are dependent on various factors including the number of vehicles, the type of vehicle, the vehicle speed and the path the vehicle takes as it moves around the site.

Estimates of overall customer numbers (over 24hrs) were taken from the existing store and typical hourly patronage was obtained from the traffic engineer. The typical hourly patronage profile over 24hrs as a percentage of total customers is presented in Figure 5.


Figure 5: Typical hourly McDonalds patronage data

We assumed this typical patronage profile also applies to the drive-through use and derived the traffic flow assumptions for this development which are presented in Table 16.

5.2.3 Customer Ordering Devices (CODs)

Measurements performed at a number of McDonalds drive through indicate that the average time that the COD is in use during an order is 16 seconds. Table 18 presents the criteria applicable to the COD noise emissions based on the numbers of cars over each time period.

The predicted noise levels at each receiver are presented in Table 19. These were predicted based on the sound power levels in Table 10 and the information presented in Table 18. In addition, since the instantaneous noise level of the COD will vary over time (speech is naturally variable), there will be a difference between the LAeq (on which the predictions are based) and LA 10 noise levels used for the assessment. To account for this at the receiver position, a 2dB adjustment has been applied. The adjustment is based on previous COD noise measurement by MDA.

5.2.4 Deliveries

The following deliveries are proposed to occur at this site:

2 main deliveries per week by a 5-10 tonne truck (main delivery).

3 - 4 bun deliveries per week by a 3-5 tonne truck (bun delivery).

The assumptions made in regard to deliveries are presented in Table 20 and the predicted noise levels at each receiver for the main deliveries are presented in Table 21. Given the lower sound power levels for the bun delivery truck, the predicted noise levels will be lower and have therefore not been presented.

5.2.5 Car park

Up to 29 car parking bays are provided for customers and staff as part of the development. We consider the noise emissions from vehicles movements within the car park are unlikely to impact on the amenity of the nearby residences since:

the development is adjacent to a major road (Canning Highway), and

vehicle movements within the car park are short duration transient events.

However, individual events such as car doors slamming or cars starting and revving can, especially at night, can have adverse impacts on the amenity of the local residents. Such events are of short duration and have therefore estimated the Lmax noise levels from such events at all nearby receivers. The estimated levels, based on the worst-case car park locations (see Appendix D), are presented in Table 22.

Regulation 14A applies to this type of activity therefore, the noise impact from waste collection at the McDonalds development was not specifically assessed against the assigned noise levels. Generic recommendations to comply with the Regulation 14A requirements are presented in Section 5.3.4.

5.3 Compliance assessment

The noise emissions from the development were assessed at the most affected receivers and against the applicable assigned noise level for the time period of interest.

5.3.1 LA 10 Assigned Noise Level

Based on the assumptions made above, night-time is the most stringent time period and therefore compliance with the night-time LA 10 assigned noise levels will result in compliance with the LA 10 for all other time periods. A summary of our assessment with the night-time LA 10 assigned noise level is presented in Table 24.

A summary of our assessment against the night-time LA 1 assigned noise level is presented in Table 25.

Deliveries only occur during the daytime period therefore a separate assessment is presented in Table 26.

5.3.4 Specified works (class 1)

In the case of this development specified works include waste collection and the cleaning of the carpark, both of which are carried out by sub-contractors. These activities will only be carried out during day time hours and sporadically. As such, they are considered class 1 works under regulation 14A.

The noise emissions from the class 1 works at the proposed development were predicted to inform the application process. However, as presented in Section 3.3, the noise emissions do not have to comply with Regulation 7 provided the works are carried out in accordance with regulation 14A(2).

To comply with the requirements of regulation 14A(2) we recommend the following:

Reversing alarms to be of the type that emits broadband noise in lieu of tonal reversing beepers

Use of impact matting under large waste bins to minimise impulsive noise

Source quietest equipment reasonably available

If reasonable and practicable, also source or modify equipment to avoid annoying characteristics


Favour use of newer equipment as they are generally quieter

Undertake regular checks and maintenance of vehicles and equipment to identify/repair noisy items.


6.0 CONCLUSIONS

Marshall Day Acoustics assessed the noise emissions from the proposed McDonalds development to be located on Lot 145 and Lot 146 on Canning Highway in Applecross.

Based on the assumptions and noise controls described in Section 4.1, our assessment demonstrates that the predicted noise emissions from the proposed development comply with the applicable assigned noise levels for all time periods at all receivers.

6.1 Annoying Characteristics

The noise emissions from the mechanical plant are unlikely to be tonal when assessed at the noise-sensitive receivers given the following:

The separation distances from sources to receiver

There is no direct line of sight between any mechanical plant equipment and receivers

Our experience on similar projects indicating that where several sources operate simultaneously, tones are masked by other sources within the development
