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

 

6 SERVICES AND FIXED PLANT NOISE

6.1 INTRODUCTION

The proposed retirement village will include a range of services and fixed plant, which have a
potential to impact the acoustic environment of the surrounding residential houses. Noise
emissions are expected to come from the following sources:

* waste collection services for all ILUs and care facility buildings;

» delivery of goods including refrigerated food to the care facility building;
« air conditioning units for all ILUs and care facitity buildings; and

* refrigeration condensers for care facility buildings.

These services and fixed plant have the potential to impact on noise amenity at both on-site
receptors (including residents of the {LUs) and off-site receptors. The nearest off-site
sensitive receptors (residential housing) are located to the east of the development, along
Trading Post road and to the north.

The following sections provide an assessment of the potential impacts of each of these
services and fixed plant items.

6.2 ASSESSMENT OF IMPACTS

6.2.1 Fixed Plant

Currently the detailed design of fixed plant items proposed for the retirement village have not
been finalised by the design team. Continuous noise sources at the site are likely to include
air conditioning and/or refrigeration plant for |LU and care facility buildings.

For the ILUs, the air conditioning units adopted for the development would be similar to those
of typical residential developments. Given the small size of the unit(s) likely to be required for
these buildings, impacts on surrounding uses (which predominantly include other ILUs) is
expected to be minimal. To minimise any potential impacts, however, it is recommended that
all condenser units for the ILU air conditioning systems be located as far as practicably
possible from sleeping areas for adjacent ILUs. Furthermore, it is recommended that, where
practical, all condenser units are located adjacent to the wall of the buildings such that there
is no angle of view to the condenser unit from any bedrooms of adjacent ILU buildings.

For the aged care facility and multi-purpose community village building, the design of the fixed
plant noise sources is not known at this stage. Given this the potential impact cannot be
predicted and a design noise limit for the plant must be specified instead. In accordance with
the Environmental Protection Regulation, a criteria based on the higher of the average
Lago noise level of 36.5 dB(A) and 40 dB(A) (refer to Table 2.2) is appropriate.
