Inundation adaptation outcomes and associated actions for Noosa Heads


The assessment of inundation risks across Noosa Heads shows the level of risk to some tourism,
business, recreational and infrastructure assets is projected to become intolerable in the later
decades of the century.

Given a range of socio-economic, environmental, and governance considerations, as well as
community feedback during the development of this plan, determine the most appropriate
adaptation pathway for responding to frequent inundation risks in this locality is one that supports
existing accessibility and infrastructure services, as well as current levels of residential, commercial
and retail development. In response to these risks, the preferred adaptation outcomes are:

   -   Use adaptive landscape design measures to mitigate risk to open space recreation and
       road network areas. This may include low level walls, seat and garden beds used to
       prevent periodic tidal inundation from spreading into parks and road areas.
   -   Increasing inundation risks to service infrastructure assets are mitigated through adaptive
       design.


Figure 18 shows the expected progression of these preferred outcomes between 2020 and 2100.
Table 17.18 provides a breakdown of actions in support of these outcomes, to be pursued within
the five -year life of this plan.
