2.0 SCOPE AND METHOD OF INVESTIGATIONS
The aim of this report is to assess the potential risk of slope instability or Landslide risk for the
proposed residential development in its existing and post developed state.

It must be noted that this report reflects the results of a qualitative risk assessment only and is not
to be seen as a slope stability analysis or design report, nor is it intended to quantify a geotechnical
factor of safety or certify the design as provided by the client.

The methodology adopted by STA Consulting Engineers in order to determine the Landslide risk for
this site is obtained incorporating the following criteria :‐

       Guidelines developed by the Australian Geomechanics Society (AGS), Landslide Risk
        Management, Volume 42 No.1, March 2007.

       Landslide Frequency Assessment in accordance with the report “A Method of Zoning
        Landslide Hazards”, prepared by MacGregor and Taylor 2001.

       A review of existing Hazard mapping (where available), aerial photographs and various
        published information to assist in identifying past activity.

3.0 PROPOSED DEVELOPMENT
The proposed development is to involve the construction of a new residential dwelling on the
established residential type property. The proposed construction is intended to replace the existing
residence and be positioned as per the attached siting plan (refer appendix D) with a nominated off‐
set distance of between 6.0 metres and 6.021 metres from the front Eastern boundary, 2.450 metres
from the Southern side boundary, between 1.555 metres and 2.591 metres from the rear Western
boundary. The construction is to comprise of a double storey dwelling with a timber floor on bearers
and joists to the upper level supported by slab on ground to the lower floor. The external finish is to
comprise of selected cladding with a sheet metal roof. A inground swimming pool and water tank
are also proposed. These structures are to be positioned to the North Western aspect of the block,
adjacent to the proposed residence. New retaining walls and a masonry block wall fence are to be
included as part of the required landscaping.

Earthworks are to involve the demolition and removal of the existing dwelling and associated
structures including retaining walls located to the rear of the block. With a nominated platform level
of R.L 17.8 AHD, it is understood that only a site scrap will be required to achieve desired ground
levels.
