 “Adamson Town Planning, specialising in providing higher order town planning advice”




reconfiguring a lot is code assessable where involving earthworks exceeding 50m3 or involving
vegetation clearing or involve redirecting the existing flow of surface or ground water.

It is noted that under Table 13.6, the assessment table for material change of use, Residential uses
except a Detached House, require assessment against the Natural Hazards Overlay Code.
Consequently, the proposed Detached House is exempted, with this issue being addressed under the
Detached House Code (O9 & S(.2)) which is discussed below.

While it is questioned that the proposed open channel drain will result in earthworks exceeding 50m3
or involve the redirection of existing flow or surface or ground water, or in a practical sense does not
involve vegetation clearing, an assessment has been undertaken against the Natural Hazards Overlay
Code.

Under Table 13.8, the assessment benchmarks are provided for Landslide Hazard Areas:

General O1 & O2:
The extension to the dwelling has been established on the land in accordance with the Building Works
Code, in particular acceptable solution S7.2, with the provision of a geotechnical report (refer
Attachment 5). The construction of the open channel area has been considered by and will be
designed by a Registered Professional Engineer of Queensland (RPEQ – Dr Johnson of SLR – refer
Attachment 4). The proposed development has been located to ensure it does not compromise the
safety of people and property and complies with specific outcome O1.

With respect to O2, the proposed development including accessways has been designed and will be
constructed to:
   a) minimise impacts on the natural landform;
   b) minimise risk to people and property from landslide;
   c) avoids any potential instability and associated problems, including long term stability of the
       site and the development.

The proposed development meets specific outcome O2. Specific outcome O3 is not relevant to the
assessment.

Other Provisions for Reconfiguring a Lot

In terms of the other codes including the Landscaping Code and Engineering Works Codes, the
proposed development either complies with or could be conditioned to comply with the relevant
assessment benchmarks.

The subject land is located within the Urban Footprint under the South East Queensland Regional Plan
2017 and makes use of available residential land which can be readily serviced in an efficient and
effective manner at minimum cost.
