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

 

7.2. ROAD TRAFFIC NOISE

The modelling of road traffic noise for a 10 year horizon from construction of the proposed aged
care development has been completed. According to the modelling results, the Department of
Mains Roads criteria is predicted by up to 9 dB(A).

Compliance with the relevant noise criteria is predicted to be achieved by implementing the
Mitigation options for rail noise impacts (as summarised in Section 7.1).

Noise levels at private terrace areas are predicted to exceed the criteria for a number of ILU
buildings located adjacent to the Cooroy Connection Road (ILU buildings 94, 97, 104, 107, 108, 115
and 116). However, a large proportion of compliant area is provided in the shadow region of each
ILU building (see Figures 10b to 10f). Hence, compiiance with the DMR criterion is predicted
provided that private open space is designated in the shadow zone of these ILU buildings.

7.3. NOISE IMMISSIONS

The assessment has considered the potential impacts of services and fixed plant including waste
collection, air conditioning and refrigeration units on surrounding sensitive land uses including both
on and off-site receptors. In addition, the impact of traffic leaving and accessing the site via
Lamonts Road has also been considered.

The following findings have been determined regarding the acoustic impact of the development on
off-site and on-site sensitive receptors:

= all fixed air conditioning and refrigeration plant installed at the proposed care facility and
community village centre is located as far as practicable from surrounding sensitive land uses;

= the total sound power level for fixed plant installed at the proposed care facility and community
village should not exceed those presented in Table 6.1 in Section 6.2.1.2. The allowable sound
power level has the potential to be higher depending on the final location of fixed plant and
whether additional shielding or acoustic enclosures are provided; and

« noise associated with deliveries at the Aged Care Facility and traffic accessing/leaving the site
via Lamonts Road is predicted to be minimal and comply with the retevant criteria.
