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

 

2 ASSESSMENT CRITERIA
2.1 ROAD TRAFFIC NOISE

The Queensland Department of Main Roads through its Road Traffic Noise Management:
Code of Practice (2000) specifies noise criteria for new and existing roads. Criteria for
proposed residential developments from the Code of Practice specify the requirements for the
current and future noise conditions as follows.

Criteria for residential development (Temporary or Permanent Occupancy) requires that:

Residential (Temporary or Permanent Occupancy)

‘Habitable Floors

" 60 dB(A) L1o (18 Hour) or less, where existing levels measured at the local government
deemed-to—comply dwelling setback distance are greater than 40 dB(A) Leo (8-Hour)
between 10 pm and 6 am; or

« 57 dB(A) Lio (18 hour) or less, where existing levels measured at the local government
deemed-to—comply dwelling setback distance are less than or equal to 40 dB(A) Loo
(8-hour) between 10 pm and 6 am

* Where the above criteria cannot be met, internal maximum design criterion levels
specified in table, AS 2107-1987.

Note: All external levels stated are free-field with the expectation that additional 2.5 dB(A)
increase is applied for the facade correction when the building is constructed. This will
achieve a level of less than 63 dB(A) and 60 dB(A), respectively, 1 metre from the most
exposed facade of a building.’

Specific guidance is also provided by the OMR for outdoor areas at developments:
‘Balconies and formal external open areas

® 60 dB(A) Lio (18 Hour) or less, where existing levels measured at the local government
deemed-to—comply dwelling setback distance are greater than 45 dB(A) Loo (18-Hour);
or

* 57 dB(A) Lio (18 hour) or less, where existing levels measured at the local government
deemea-to—comply dwelling setback distance are less than or equal to 45 dB(A)
Loo (18-hour).’

The above criteria has been considered for the purposes of this noise assessment.
