6.2 Noise impacts from Pool Area

In section 5.4 of this noise impacts from the Pool Area were modelled and assessed against the Background
Creep Criteria from the Environmental Protection (Noise) Policy 2008. This assessment determined that
some noise impacts from this area would exceed this criteria.

In order to mitigate the noise impacts from the pool area on these neighbouring properties it is 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 over the page. 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 barrier would be constructed adjacent to retaining wall and would have a gap to allow
drainage. The arrangement of the barrier and retaining wall are also shown on the diagram over the page.

Modelling of the mitigation provided by the proposed acoustic fence has been conducted in the appendix to
this report. Details of this modelling are included in the appendix to this report. The results of the modelling
are presented in the table below and show all noise impacts from the pool area will now comply with the
Background Creep Assessment Criteria from the Environmental Protection (Noise) Policy 2008.

In addition to the proposed 1.8 m acoustic barriers to further limit the noise impacts from the pool area
overnight is also proposed to limit the hours of the Pool to between 7.00 am to 9.00 pm seven days a week.
