 (1)    The purpose of the Flood Hazard overlay code is to:
        (a)   provide for the assessment of the compatibility of development in the flood hazard overlay to flood and storm tide inundation
              risk, taking into account the predicted effects of climate change;
        (b)   ensure that risk to life, property, community, economic activity and the environment during flood and storm tide inundation
              events is avoided or mitigated; and
        (c)   ensure that development does not increase potential for flood damage on­site or to other property.

 (2)    The overall outcomes sought for the Flood Hazard overlay code are:
        (a)   Development in areas at risk from flood and storm tide inundation is compatible with the nature of the defined flood event or
              defined storm tide event.
        (b)   Development protects floodplains and the flood conveyance capacity of waterways.
        (c)   Development is resilient to flood and storm tide events by ensuring siting and design responds to and minimises potential
              risks of flood and storm tide inundation to people and property.
        (d)   Development directly, indirectly and cumulatively avoids an unacceptable increase in the extent or severity of flood or storm
              tide inundation and does not significantly increase the potential for damage on the site or to other properties.
        (e)   Development supports and does not unduly burden disaster management response or recovery capacity and capabilities.
        (f)   Development avoids the release of hazardous materials as a result of a flood event.
        (g)   Natural processes and the protective function of landforms and vegetation are maintained in flooding and inundation areas.

  Floodplain protection, immunity and safety ­ for development areas

  Development provides that for all flood events up to and            The finished flood level is not less than the minimum design
  including the DFE :                                                 levels specified in Table 8.2.6.4
  (a)    the safety of people on the site is protected; and
  (b)    the risk of damage to property on the site is avoided or
         minimised as far as practicable.


  PO2                                                                 AO2

  undertaken in a manner that ensures:
  (a)    natural hydrological systems are protected from erosion,
         scour or flood damage on the premises or other premises;
  (b)    natural landforms and drainage lines are maintained to
         protect the hydraulic performance of waterways and flood
         plain; and
  (c)    development integrates with the natural landform rather
         than modifying the landform to suit the development as far
         as practicable.
