                   Table 1819 - Change in Noosaville asset risk profiles across planning horizons


The existing methods for mitigating inundation risks in Noosaville are:

   -   Planning and land use regulations are in place including minimum floor heights for new
       buildings
   -   Minor revetment walls along the Noosa River shoreline.


Adaptation outcomes and associated actions for Noosaville

The assessment of inundation risks in Noosaville show the level of risk across all asset types in
areas adjacent to the Noosa River is likely to become intolerable by the year 2070.

Given a range of socio-economic, environmental, and governance considerations, as well as
significant levels of community feedback throughout the CHAP’s development, the most suitable
and feasible adaptation pathway for responding to inundation risks in this locality is one that
supports existing recreational and visual amenity values, accessibility and infrastructure services,
and current levels of residential, commercial and retail development.

As a result, the preferred adaptation outcomes for this locality are:

   -   Implement measures that protect important recreational areas, stormwater network, road
       and footpath assets from periodic tidal inundation
   -   Where possible, re-locate major recreational and infrastructure assets (e.g. amenities
       blocks) outside the project high -risk foreshore areas by 2070
   -   Where important recreational assets (e.g. Apex Park) cannot be feasibly re-located, seek to
       accommodate the risks by adapting the design of these assets (e.g. tolerant vegetation
       types) to be more resilient during and after inundation events
   -   Re-design important service infrastructure networks (e.g. road corridors) to be more
       resilient to projected changes in hazard extents.
