    1. ≤35 dB(A) Leq (1 hour) (maximum hour over 24 hours).

NOTE: Facade correction is +2.5 dB(A) to the free field result.

PO24     Development involving an accommodation activity or land for a future accommodation activity
         minimises noise intrusion from a state-controlled road or type 1 multi-modal corridor in outdoor
         spaces for passive recreation.

AO24.1 A noise barrier or earth mound is provided which is designed, sited and constructed:

    1. to meet the following external noise criteria in outdoor spaces for passive recreation:

              a. ≤57 dB(A) LA10 (18 hour) free field (measured LA90 (18 hour) free field between 6 am
                 and 12 midnight ≤ 45 dB(A);
              b. ≤60 dB(A) LA10 (18 hour) free field (measured LA90 (18 hour) free field between 6 am
                 and 12 midnight > 45 dB(A).

    2. in accordance with 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.

OR all of the following acceptable outcomes apply:

AO24.2 Each dwelling has access to an outdoor space for passive recreation which is shielded from a
       state controlled road or type 1 multi-modal corridor by a building, solid gap-free fence, or other
       solid gap-free structure.

AND

AO24.3 Each dwelling with a balcony directly exposed to noise from a state-controlled road or type 1
       multi-modal corridor has a continuous solid gap-free balustrade (other than gaps required for
       drainage purposes to comply with the Building Code of Australia).

Additionally, habitable rooms within a transport noise corridor must comply with the Queensland
Development Code MP4.4, Buildings in a Transport Noise Corridor.
