       dune areas, thereby preserving natural coastal processes of erosion and accretion.


Preferred Aadaptation outcomes and associated actions for Peregian Beach

The assessment of erosion risks in Peregian Beach shows that the level of risk to some recreation
and infrastructure asset types is expected to may become intolerable by mid-late century.

Analysis of economic, social, and environmental considerations, as well as multiple legal and
governance constraints and significant input from the Noosa community indicates the most suitable
and feasible adaptation pathway in this locality is one that provides continuous support for natural
coastal processes and existing beach use, amenity, and adjacent recreational values by
implementing natural coastal protection solutions and a medium- to long-term transition of built
environment and recreational and infrastructure assets away from high erosion risk areas.

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
   -   Re-locate important recreational and service infrastructure assets outside the projected
       high risk coastal erosion prone area by 2070
   -   Where important recreational and service infrastructure assets cannot be feasibly re-
       located, seek to accommodate the risks by adapting the design of these assets to be more
       resilient during and after a major erosion event.

Figure 12 shows the expected progression of actions to support these preferred outcomes
between years 2020 and 2100. Table 5 provides a breakdown of actions in support of these
outcomes, to be pursued within the five year life of this plan.
