2021-11-15 GC Agenda - Item 7 - Attachment 1 - Coastal Hazards Adaptation Plan

                                                                        Noosa Coastal Hazards Adaptation Plan



Based on expert technical advice and feedback received through a series of community surveys and
workshops, a range of assessment criteria were applied to a list of 53 potential adaptation options for
assets and locations where risks are considered high or very high. These criteria are shown in Table 324.
The purpose of this stage of the project was to determine which of these adaptation options are likely
suitable for Noosa or which might work, but for one reason or another, require further work to determine
their feasibility. This stage also assessed those options 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.

     Criteria          Criteria Description
     Cost              Monetary costs to build/implement an adaptation option (further detailed studies
                       to confirm costs may be required), either by Council or private landowners
     Environmental     Whether an adaptation option will have adverse impacts on environmental values
     Impact            e.g. Matters of State Environmental Significance
     Social Impact     Whether an adaptation option will have adverse impacts on other 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 future needs
     adaptable
     Effectiveness     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 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 3 - Adaptation options assessment criteria

                                    Assessing adaptation options
        Using the criteria set out in Table to score each option, a “traffic light” system was then used
        to group the options for deliberation as follows:
        •	
          Proceed (‘GO’): 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 (‘SLOW’): an option may be suitable, but should be subject to further
          detailed assessment at specific locations e.g. cost-benefit analysis or lot-scale surveys
        •	
          Unfeasible (‘STOP’): an option is not considered suitable at a location and may not be
          considered for further detailed analysis.
