Proposed RSL Retirement Village, Cooroy — Road and Rail Noise Assessment SS

 

The design limit for any continuous fixed plant at the proposed aged care facility has been
calculated on the basis of the following assumptions:

» a 40 dB(A) noise limit (as specified in the EPP(Noise)), which the total noise level from
all continuous noise sources must not exceed;

* aminimum source to receptor distance of 25 m (for closest ILU); and

+ all plant are located in direct line of sight of the nearest neighbouring property (ie, they
are not shielded by the roofline or other structures or topographic features).

On the basis of these assumptions, the total sound power level from all continuous noise
sources at the site must be a maximum of 76 dB(A) to ensure that the specified night-time
criteria of 40 dB(A) is not exceeded at the nearest receptor position. If all noise sources are
shielded from the nearest receptors a sound power level of 86 dB(A) or more may be
acceptable depending on the height of the sources relative to the acoustic screening and the
type of structure involved.

It is recommended that continuously operating plant are located as far as possible from
proposed potentially sensitive development.

6.2.2 Loading Dock Noise

The proposed site layout has an area designated for service access associated with the aged
care facility, as shown on Figure 2. The regular services associated with the aged care facility
will most likely include refrigerated food trucks and waste disposal services. Based on site
survey plans, the minimum distance to the nearest sensitive receptors is 50 m (one-storey
residential house to the north of the development site).

Given the short-term nature of the above noise sources, the appropriate criterion to use for
assessing the acoustic impact is a background Laio plus 3 dB(A) noise level. Noise monitoring
Position 2 indicates an Laio noise level for the period between 7 am to 6 pm to be 56.1 dB(A).
Hence, a 59.1 dB(A) criterion is adopted. The 56.1 dB(A) noise level was measured during a
weekday, when the majority of service vehicles are expected to make deliveries.

Table 6.1 presents a summary of maximum source noise levels for refrigerated truck
deliveries and waste disposal vehicles measured by Air Noise Environment personnel.
Table 6.2 presents a summary of maximum predicted receptor noise levels for each of the
sources identified in Table 6.1.
