Helitak MCU App - Planning Report

7.4 Biodiversity, Waterways and Wetlands Overlay Code

The shed is located in the Riparian buffer area. The use is not using any highly toxic chemicals and
is a far less environmental risk than the previous agricultural uses (intensive cropping and turf farm).
As part of the previous approval for intensive cultivation, the shed’s location in the riparian buffer
area was scrutinised and considered to comply with the code.

A small 72m² office building is proposed generally within the existing footprint given car parking
previously occurred in the office location. In support of the application, the applicant is proposing
to regenerate with tube stock the equivalent area of the new building within the riparian buffer.

The proposal complies with the Biodiversity, Waterways and Wetland Overlay Code as all
development is contained generally within the existing footprint and regeneration with native tube
stock of the equivalent area to the office is proposed in the riparian buffer.



7.5 Flood Hazard Overlay Code

The site is known to flood and was highly scrutinised in the previous approval for intensive cultivation
which included the existing shed subject of this application. Performance Outcome PO1 and PO11
are relevant and provided below for reference.



PO1
Development      provides   that   for   all   flood    events     up   to    and   including   the   DFE :
(a)      the safety of people on the site is protected; and

(b)      the risk of damage to property on the site is avoided or minimised as far as practicable.

PO11
Development ensures that public safety and the environment are not adversely affected by
avoiding the release of hazardous materials into flood waters and the environment.

The Flood Assessment prepared for the previous intensive cultivation approval is a public document
and indicates that including the subject shed and the greenhouse, there is a no flood worsening at
the boundaries of the site. Given there is no further building works as part of this proposal, other
than a small demountable type office on skids which allows for the free flow of flood waters, no
change to the impact on the flood plain will occur.

The applicant is also willing to provide an early warning flood system to Six Mile Creek to ensure
there is ample time to evacuate to higher ground. As indicated in the Flood Assessment under the
previous approval, there is a minimum of 2 hours from the time Six Mile Creek reaches 92m AHD at a
location along the sites south western boundary.

The Helitak Fire Fighting Equipment Pty Ltd CEO will reside in the Dwelling house located near the
Lake Macdonald Drive frontage which will ensure any flood management plan is activated so staff
and delivery entry to the site is not accessed during flood events.
