2.2         Site Inspection
A site inspection was undertaken by Paul Prenzler and Andrew Fielding on 23 September 2021 to observe
the site conditions and undertake field measurements of the beach.

The ‘seaward toe of the frontal dune’ was mapped using a handheld GPS to assist with determining the
erosion prone area width at the site. The ‘seaward toe of the frontal dune’ was determined based on the
guidance provided in the ‘Coastal Hazards Technical Guide’ (Department of Environment and Heritage
Protection, 2013) and the notes of NOS3A dated 8 July 2015 prepared by the Department of Environment
and Science (refer Appendix B). Figure 1 shows the ‘seaward toe of the frontal dune’ on Sunshine
Beach near the subject site in 2019 and 2021.

The distance from the rear property boundary of the site to the toe of the frontal dune approximately 90
metres.

2.3         Geotechnical Investigations
The geotechnical conditions at the site have been investigated by Tectonic Geotechnical Pty Ltd. The
scope of the geotechnical investigation includes the design of the house foundations to mitigate impacts
on the structure from potential beach erosion.

2.4         Survey
Survey of the site and adjoining beach system was undertaken by Minstaff Survey Pty Ltd on the 6th
October 2021. The survey is presented in Appendix C.

The survey has been supplemented with survey information from ETA 602 to describe the beach profile
through the surf zone to the depth of closure. This is consistent with the approach adopted by BMT
(2018).
