                                33 Ross Crescent, Sunshine Beach – Coastal Hazzard Assessment | 33 Ross Crescent Family Trust



BMT calculated a dune slumping factor of 16m, and RHDHV computed a factor of 8m.

6.5.     Comparison summary
Comparison of the BMT (2018) and RHDHV erosion prone area assessment has identified that the primary
differences are related to the beach profiles, dune heights, storm tide levels adopted, where the short-term
erosion is measured and the method used to calculate dune slumping. The assessment undertaken by
BMT (2018) was a broader scale assessment to determine the erosion prone area at a beach compartment
level. In comparison, the assessment presented in this report is a site-specific assessment.

It is recommended that the erosion prone area assessment undertaken for this report is representative of
the current erosion vulnerability for the subject properties and is consistent with the ‘Coastal Hazards
Technical Guide’ (Department of Environment and Heritage Protection, 2013). The assessed erosion prone
area width of 85m measured from the toe of the frontal dune (refer Figure 6-7) should be adopted in relation
to the current development application related to building works within an erosion prone area and coastal
management area for 33 Ross Crescent, Sunshine Beach.
