ATTCH 4 - IR Response - UXO vegetation clearance (Opec Systems)

method of clearing and survey in environmentally sensitive areas across Australia, including the Noosa
National Park.

A Digital/Analog survey will be undertaken over developable areas of the site, namely those areas identified
as “Building Envelope,” “Asset Protection Zone – Driveway,” and “Covenant (Bushfire Risk and Stormwater
Management) Area” identified on the Subdivision Layout Plan (Attachment 1) and the Vegetation
Management Plan – Occupation Phase (refer to John Delaney response). To enable an Digital/Analog survey
all vegetation will need to be reduced to a height of approximately 50mm above ground.

Figure 1 identifies the extent of clearing on the site in accordance with the above discussion. Areas marked
in green will involve minor clearing by hand/brushcutter for the purpose of a visual surface survey. Areas
marked in red will involve de-vegetation for the purpose of Digital/Analog survey. Figure 1 is indicative and is
intended to reflect the Covenant Area’s identified in the Subdivision Layout Plan (Attachment 1), Vegetation
Management Plan – Occupation Phase (refer to John Delaney response) and Vegetation Management Plan –
Construction Phase (refer to John Delaney response).

If there is any significant vegetation on the site which is sensitive to clearing as identified by a Vegetation
Management Plan, Clearing Permit or in consultation with the applicants ecologist (John Delaney – Cardno)
or otherwise, then that vegetation can be marked and excluded from clearing for the purpose of the survey.
It is noted that there may be requirement for a services trench to be excavated within the Environmental
Covenant (Habitat Protection) Area during the construction phase of the sub-division. This is indicatively
shown in the Vegetation Management Plan – Construction Phase by the green hatch (refer to John Delaney
response). If that is the case, then de-vegetation to enable Digital/Analog survey will be required in the area
of that trench. In accordance with the Vegetation Management Plan – Construction Phase the cleared area
would then be rehabilitated after construction of the services.
