2021-10-08 SM - Item 1 - Attachment 1 - Draft Coastal Hazards Adaptation Plan

   -   Planning controls on coastal development that prevent encroachment into the vegetated
       dune areas, thereby preserving natural coastal processes of erosion and accretion.


Preferred adaptation 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 may become intolerable by mid-late century.

Analysis of economic, social, and environmental considerations, as well as multiple legal and
governance constraints and 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
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 infrastructure assets outside the projected high risk
       coastal erosion prone area by 2070
   -   Where important recreational and 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.
