             Table 10 - Change in Noosa Heads asset inundation risk profiles across planning horizons


At present, the only method for mitigating inundation risks in Noosa Heads is:

    -   Planning and land use regulations are in place for new development including minimum
        floor heights for new buildings.


Adaptation outcomes and associated actions – Inundation


The assessment of inundation risks across Noosa heads show the level of risk to some tourism,
business, recreational and infrastructure assets is likely 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.
