                       OR all of the following acceptable outcomes apply:

                       AO23.2 Buildings which include a habitable room are
                       setback the maximum distance possible from a state-
                       controlled road or type 1 multi-modal corridor.
                       AND
                       AO23.3 Buildings are designed and oriented so that
                       habitable rooms are located furthest from a state-
                       controlled road or type 1 multi-modal corridor.
                       AND
                       AO23.4 Buildings (other than a relevant residential
                       building or relocated building) are designed and
                       constructed using materials which ensure that
                       habitable rooms meet the following internal noise
                       criteria:
                           1. ≤35 dB(A) Leq (1 hour) (maximum hour over 24
                                hours).

                       Statutory note: Noise levels from a state-controlled
                       road or type 1 multi-modal corridor are to be
                       measured in accordance with AS1055.1–1997
                       Acoustics – Description and measurement of
                       environmental noise.

                       Note: To demonstrate compliance with the acceptable
                       outcome, it is recommended that a RPEQ certified
                       noise assessment report is provided, prepared in
                       accordance with the State Development Assessment
