    a) ≤65 dB(A) Leq (24 hour) facade corrected

AND

    b) ≤87 dB(A) (single event maximum sound pressure level) facade corrected.


Table 2, Item 2.2 states the following rail noise limits:

    c) ≤62 dB(A) Leq (24 hour) free field

AND

    d) ≤84 dB(A) (single event maximum sound pressure level) free field.


Noise Limits – Traffic

In accordance with the State Development Assessment Provisions State Code 1: Development in a
state-controlled road environment, Version 3.0, Table 1.5 Environmental Emissions and the associated
reference tables (Table 1, 2 and 3) the state controlled road noise limits for ‘accommodation activities’
are, for all facades:

Ground floor level requirements adjacent to a state controlled road

PO39     Development minimises noise intrusion from a state-controlled road in private open space.

AO39.1 Development provides a noise barrier or earth mound which is designed, sited and constructed:

    1. to achieve the maximum free field acoustic levels in reference table 2 (item 2.2) for private open
       space at the ground floor level.

         In accordance with Table 2 the acoustic levels are:
             a) ≤57 dB(A) L10 (18 hour) free field (measured L90 (18 hour) free field between 6am and
                 12 midnight ≤45 dB(A));

         OR

              b) ≤60 dB(A) L10 (18 hour) free field (measured L90 (18 hour) free field between 6am and
                 12 midnight >45 dB(A))

    2. in accordance with:
           a. chapter 7 integrated noise barrier design of the Transport Noise Management Code of
               Practice: Volume 1 (Road Traffic Noise), Department of Transport and Main Roads,
               2013;
           b. Technical Specification-MRTS15 Noise Fences, Transport and Main Roads, 2019;
           c. Technical Specification-MRTS04 General Earthworks, Transport and Main Roads,
               2020;

         OR

AO39.2 Development achieves the maximum free field acoustic level in reference table 2 (item 2.2) for
private open space by alternative noise attenuation measures where it is not practical to provide a noise
barrier or earth mound.

PO40 Development (excluding a relevant residential building or relocated building) minimises noise
intrusion from a state-controlled road in habitable rooms at the facade.
