RSL Care
Proposed RSL Retirement Village, Cooroy - Road and Rail Noise Assessment (Revised)

 

Table 6.2 presents Lama noise source measurement data for rubbish collection and refrigerated
trucks completed previously by Air Noise Environment personnel. Table 6.2 presents a summary of
maximum predicted receptor noise levels for each source.

Boid represents exceedance in the noise criterion

As indicated by Table 6.2, noise levels associated with refrigerated truck deliveries are predicted to
comply with the Lai noise criterion for the residential house located to the west on Lot 1. Noise
levels at the nearest ILUs are predicted to exceed the criteria by up to 63 dB(A).

Given the predicted noise attenuation provided by recommended construction materials for road
and rail noise mitigation, the impact on internal Lame noise levels at the nearest ILUs is predicted to
be minimal. As identified on Table 5.5, the recommended noise reduction for construction materials
for Bedroom 1 of ILU No. 88 and Bedroom 2 of ILU No. 126 are 23 and 27 respectively. Hence, an
internal Lamax noise level of 37 dB(A) (ILU No. 88) and 36 dB(A) (ILU No. 126) is predicted.

6.2.3 Traffic Accessing/Leaving the Site

Access points for vehicles are proposed along Lamonts Road at the north-west corner of the site.
The access point is proposed to be used by service vehicles (e.g. delivery trucks and rubbish
collection trucks) and by residences occupying the residential buildings (ie. ILUs and 20 Unit
Apartment). The Noosa Shire Council has requested that potential noise impacts on the residential
house on Lot 1 be assessed.

Traffic data provided by the client indicates that the peak AM and PM vehicles movements are
