SCG 0599 - Landslide Risk Assesment

Based on the provided plans, it is understood that the existing residence will be demolished, and a new 2-
storey residence with a partial inground garage basement and a semi-inground pool will be constructed.

A previous geotechnical report has been provided for the eastern neighbouring property located at 66 Peregian
Esplanade by Pacific Geotech. The geotechnical investigation comprised the drilling and sampling of five (5)
boreholes extending to depths ranging between 0.5 m and 7.4 m (drill rig refusal). The investigation
summarised the site as comprising very loose grading to very dense sand grading with depth. Ground water
was noted ranging between 2.6 m and 3.3 m below ground level. It is typical for groundwater to fluctuate
regularly throughout the area.

The provided report, in conjunction with local experience, is consistent with available mapping as shown in
Figure 3 below.

Noosa Shire Council mapping indicates that the proposed site is mapped ‘moderate hazards area’, as shown
in Figure 4.
