This section of coast is vulnerable to inundation in discrete areas. It is noted that subsequent risk assessments will be required for this part of the coast to combine the hazard and risk findings in order to produce a holistic picture of the overall vulnerability.

Inundation vulnerability is presented for St Leonards Lake Reserve (Figure 6-24) and Salt Lake (Figure 6-25). The hazard is low at St Leonards Lake Reserve, impacts become more significant with sea-level rise increases over 0.2 m in a 1% AEP event. The inundation hazard at Salt Lake shows the shoreline overwashing in a present day 1% AEP event (i.e. no sea-level rise). The difference here, compared with the previous hazard maps where large section of shoreline are overwashed and inundated, is that there are three particular spots along the shoreline lower than adjacent areas that will allow inundation to occur in the present day 1% AEP event. These are shown as breach locations in Figure 6-25. This information will aid in further risk and options assessments.

There is a significant inundation hazard at Indented Head near Andersons Reserve to the Esplanade at Portarlington (Figure 6-26) and Ramblers Road (Figure 6-27). These areas are both extremely low and flat. There is little to no dune formation fronting the hinterland, and low wooden retaining walls holding the shoreline in place in some locations.
