            Criteria         Criteria Description
                             Whether an adaptation option will have adverse impacts on other
            Social Impact    social values or is likely to have community support e.g. access,
                             amenity, property values
            Reversible/      Whether an option is able to be ‘reversed’ or adapted to cater for
            adaptable        future needs
                             Whether an option is technically feasible (i.e. is effective in
                             mitigating the risk and is implementable)
                             Whether an option is able to be readily approved (i.e. is
            Effectiveness
                             consistent with current planning policy or legislative requirements)
                             Whether an option provides a long-term solution to the coastal
                             hazard risk, or is suitable for use as an interim option
                                 Table 2 - Adaptation options assessment criteria

The purpose of this stage of the project was to determine which of these adaptation options are
highly likely to be suitable for Noosa or which might work but for one reason or another require
further work to determine their feasibility, as well as those that are very likely to be ineffective or
unfeasible for inclusion in this plan. Reference Box #3 explains how each of the options were
assessed and categorised.

                                       Assessing adaptation options

 Using the criteria set out in Table 2 to score each option, a “traffic light” system was then used to group
 the options for deliberation as follows:

     •   Proceed: an option is considered suitable with no other adverse impacts, and requires no further
         development (i.e. studies, design etc). These could also be defined as “No Regrets” options
     •   Investigate Further: an option may be suitable, but should be subject to further detailed
         assessment at specific locations i.e. cost-benefit analysis
     •   Unfeasible: an option is not considered suitable at a location and may not be considered for
         further detailed analysis.



Having gathered information on potential adaptation options, an important next step in the project
was to undertake more detailed and rigorous socio-economic analyses (known as a cost-benefit
analysis) of the short-listed options using a range of social, environmental and economic criteria,
data and other information. This component was critical to informing the selection of the adaptation
actions presented in this plan.

For the most part, options included for this final stage of analysis were those that scored highly
within the ‘Investigate Further’ category. In addition, based on feedback from Council staff and the
community, it was determined that a number of options rated as ‘Unfeasible’ should also be
included to provide greater certainty and confidence that these actions should not form part of a
coastal hazards adaptation plan for Noosa.
