    Performance Outcome                                          Acceptable Outcome
                                  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.
                                  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).

Based on the measured noise levels in Section 5, the applicable criteria for the development is as
follows:
                               Table 4: Applicable SDAP Road Traffic Noise Criteria

                               Location                               Noise Level dB(A)
                                                  External Criteria
                     All facades of accommodation
                                                                       LA10(18hr) 60 dB(A)
                       activities (façade corrected)
                    All passive recreation areas in an

                   accommodation activity (free field)


6.1.2   Queensland Development Code MP4.4 - Road Traffic Noise
To determine the minimum design requirements for any accommodation buildings located in a
transport noise corridor (state-controlled roads), the Queensland Development Code Part 4.4 may
be applied if no alternative solutions are provided. In accordance with MP4.4, the noise categories
are stated in Table 5.

                     Table 5: Queensland Development Code Noise Categories – Road Traffic
                                                                  Noise level L10 (18hr) dB(A)
                                 Category
                                                                  (including façade correction)
                                Category 4                                     ≥ 73
                                Category 3                                    68-72
                                Category 2                                    63-67
                                Category 1                                    58-62
                                Category 0                                    ≤ 57


The building treatment for any future development onsite shall be determined at Building Approval
stage, in general accordance with the Queensland Development Code. Alternative solution may be
provided on request.
