2.3 Assessment of Site Features and Relative Frequency Analysis

Noosa Council’s Noosa Plan 2020 Landslide Hazard Overlay Map has identified the site as having a
landslide risk potential (> 15% slope).
An extract from the Landslide Overlay map showing the site is presented in Figure 4, and highlighted in
green.
