Adaptation outcomes and associated actions

The assessment of erosion risks in Marcus Beach and Castaways Beach show the level of risk to
most assets is acceptable, however the risk to a section of David Low Way is expected to become
intolerable by the year 2070. Therefore, the most suitable adaptation pathway for this locality is
one that supports the provision of accessibility to residential communities currently dependent on
David Low Way.

As a result, the preferred adaptation outcomes for this locality are:

   -    Implement measures that support and enhance dunes, beach health and natural coastal
        processes as soon as possible
   -    Prevent the construction of hard protective structures where possible that are likely to
        exacerbate erosion risk, impact on preferred outcomes for dune and beach health, impair
        natural coastal processes, and lead to adverse impacts on neighbouring areas
   -    Seek to accommodate the risk to major infrastructure through (i.e. David Low Way)
        adaptive design in order to increase resilience during a major erosion event, and ensure
        continued functionality post-event.

The following actions will help progress the achievement of these outcomes:
