Applicant Brennan Planning Pty Ltd
Proposal Additions to Dwelling house (Building Works in Landslide Hazard
Overlay)
Memo Completed Date 25 October 2023
Memo Reviewed By Nadine Gorton 25.10.2023
PROPERTY DETAILS
Property Address 24 Attunga Heights, Noosa Heads
RP Description Lot 15 on RP89506
1. DETAILS
The proposal seeks an exemption for alterations and additions to an existing dwelling house
located on land described as Lot 15 RP89506 and addressed as 24 Attunga Heights, Noosa
Heads.
The Planning Act 2016 allows exemption certificates to be issued where ‘the effects of the
development would be minor or inconsequential, considering the circumstances under which the
development was categorised as assessable development’.
The Low Density Housing Code includes an error in that an ‘or’ has been excluded between
Acceptable Outcome AO22.1 and AO22.2 and that a slope stability report would satisfy the
acceptable outcomes if the report demonstrates as low or very low risk.
The applicant has provided a slope stability letter from SCG Consulting Engineers, Reference
Number: 29095(L1)) stating the following:
“Regarding the above site address, SCG Consulting Engineers performed a geotechnical
assessment of the property 21/05/2019.
The slope of the block was measured at 5% over the building site and 20% at the rear of the
property. Although mapping indicates a moderate risk of slope stability there is no indication
that a risk of instability exists on this block.
On further discussion with the design engineer and our RPEQ we feel a slope stability
assessment would not be required.”
Given the slope stability investigations previously performed on the site and no earthworks required
to establish the proposed deck, the development is considered minor and is not expected to cause
an adverse impact on the site. The proposed works limited to the first floor of the building and is
unlikely to cause an increased risk to the existing dwelling or adjoining properties.
