      4.     Conclusions
             The objective of this report is to assess the proposed development works with relation to
             Noosa Shire Council’s (NSC) Flood Hazard Overlay Code. Detailed volumetric and planning
             methodologies have been undertaken for this assessment.

             As part of the development application, it is proposed to construct a new dwelling on the
             existing filled pad. Earthworks will be required as part of the application to maintain flood
             storage during the defined flood event.

             Results show that the development area would provide up to 4628.62m3 of flood storage
             capacity during the defined flood event (1% AEP event), an increase in flood storage capacity
             from the existing site conditions. As such, the proposed development works are considered
             to not cause an adverse impact to neighbouring properties or the surrounding area.
             Developed site contours are presented in Figure 2, Appendix C.

             The proposed development involves constructing a dwelling at RL3.50m AHD. The floor level
             of the proposed dwelling therefore complies with the minimum flood planning level as
             specified in section 3.0.

             The proposed dwelling is to be structurally designed to be able to resist hydrostatic and
             hydrodynamic loads associated with flooding up to and including the 1% AEP flood event
             (maximum flow velocity of 1.20m/s and maximum flood depth of 0.7m).

             The Flood Hazard Overlay Code has been addressed in Appendix D of this report.
