logical access to the aged care facility and allows the use to operate separately to the adjoining retirement
community. This proposed relocation results in no need for staff and visitors for the aged care facility to
traverse the retirement community and allows convenient access to the facility just off Eim Street. The
proposed access driveways and parking area for the amended aged care facility have been supported in the
attached Traffic Report (Appendix 1).

The proposed layout of the single storey aged care facility allows every ensuited and oversized room to gain
direct access to open space and be sufficiently setback from the property boundaries. The design of this
facility is based on the proven successful design principles of other existing Palm Lake Care facilities. Please
refer to Appendix E for the proposed Aged Care Facility Plans prepared by Interworks Architects.

Acoustics
A new Acoustic report has been prepared for this proposed amended development. The results and
recommendations of the assessment by ASK Consulting are as follows:

e Anise barrier is proposed for the roadside boundaries. The barrier is modelled as 2.0 metres to 3.5
metres high based on the proposed ground levels provided to ASK.

It is noted that the proposed noise barrier along Elm Street that is 3.5m high is very long and
relatively high for what appears to be a road carrying only minor to moderate traffic volumes. This is
due in part to the strict noise criterion being a quiet area, and the undulating terrain. It is noted that
in the previous ASK noise report for this site, the barrier height was restricted to 2.1m, resulting in
higher noise exposures at dwellings but accommodating this through more significant acoustic
upgrades for the dwellings. It is likely that any relaxation of the barrier height would require
acceptance from TMR and Council.

It is requested that a reduction in the 3.5m barrier fence be considered by TMR and Council and
alternatively allowing the 2.1m high fence with additional acoustic barriers through use of building
materials (e.g double glazed windows). Palm lake Works wish to discuss this option further with TMR
and Council.

e To achieve the target noise reductions from external noise to internal noise levels in MP4.4 will
require the construction details are of an appropriate acoustic standard, and that all external
openings to be closed when these habitable rooms are occupied.

e To achieve the target noise reductions from external noise to internal noise levels in MP4.4 will
require the construction details are of an appropriate acoustic standard, and that all external
openings to be closed when these habitable rooms are occupied. Therefore, an_air-
conditioning/mechanical ventilation system that does not degrade the internal acoustic environment
or the sound isolation of the building envelope, and also meets the ventilation requirements of the
Building Code of Australia may need to be installed.

Compliance with the above recommendations is predicted to result in compliance with relevant noise
criteria. Please refer to Appendix J for a copy of the Acoustic Report prepared by ASK Consulting
