Inundation adaptation outcomes and associated actions for Noosa North Shore

The assessment of inundation risks within Noosa North Shore shows the level of risk to residential
and road network assets may become intolerable within approximately 20 years. Intolerable risks
to natural areas and biodiversity are more likely than not to eventuate by the year 2070.

Assessment of 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 services, visual amenity values and natural ecological processes. Therefore,
the preferred adaptation outcomes are:

    -   The increased inundation risk to service infrastructure assets is accommodated through
        adaptive design.


Figure 16 shows the expected progression of these preferred outcomes between 2020 and 2100.
Table 14. provides a breakdown of actions in support of these outcomes, to be pursued within the
five -year life of this plan.




 Pathways Map Legend
 Star = trigger points (points in time for when a decision needs to be made)
 Circle = commencement or future commencement of adaptation option
 Green solid line = active action on this adaptation pathway
 Green dotted line = effectiveness of this option may be reduced and require
 reassessment
