2.1

ASSESSMENT CRITERIA
RAIL NOISE

The Noosa Shire Council has specified an internal average Lame noise criteria of 50 dB(A) and
55 dB(A) for sleeping and living areas respectively. This criteria has been used for the assessment
of rail noise from the Cooroy Rail Corridor located to the west of the development site.

2.2

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) Lio (18 Hour) or less, where existing levels measured at the local government
deemed-to—comply dwelling setback distance are greater than 40 dB(A) Loo (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, intemal maximum design criterion levels specified
in table, AS 2107-1987.

Note: All extemal 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 DMR 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
deemed-to-comply dwelling setback distance are less than or equal to 45 dB(A) Ls0(18-
hour).’

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