7.0 DISCUSSION & CONCLUSIONS

The proposed development is located adjacent to a commercial building to the north and a storage yard for a
scaffold business to the east. Noise impacts from these businesses on the proposed development have been
considered in this report. In line with SC6.2.4 Appendix 1 - Requirements for technical assessments and
reports of the Noose Shire Plan 2020 reference was made to both the requirements of the Acoustic quality
Objectives for the Environmental Protection (Noise) Policy 2008 (EPP Noise) and Australian Standard AS
2107 Acoustics – Recommended design sound levels and reverberation times for building interiors. In order
to satisfy both these standards a series of acoustic treatments have been recommended to be applied to the
dwellings in order to achieve the internal noise levels from both of these standards. Details of these acoustic
treatments have been details in Section 6.1 of this report.

Noise impacts from the proposed pool area in the south east corner of the site on neighbouring properties
was also consider in Section 5.4 of this report. This assessment determined that noise impacts from the Pool
Area would exceed the Background Creep Criteria from the Environmental Protection (Noise) Policy 2008. In
order to mitigate the noise impacts from the pool area on these neighbouring properties it has been
recommended that a 1.8 m high acoustic fence be constructed along boundary of the site adjacent to this
area. The location of this fence is show Section 6.2 of this report. The proposed acoustic barrier would be
solid, gap free and achieve a surface density of at least 11 kg/m2. The barrier could be constructed of
double lapped timber, fibre cement or masonry.

The development is also not located within a Transport Noise Corridor and as such the impacts of transport
noise on the development have not been considered.

Subject to our calculations, the recommended acoustic building treatments, the proposed acoustic fence
adjacent to the pool area and conditions relating to hours of operation of the pool area, we believe that the
development will meet all requirements of Dual Occupancy and Multiple Dwelling Code of the Noose Shire
Plan 2020 and should be approved.
