 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.

 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

 c)   development integrates with the natural landform rather
      than modifying the landform to suit the development as far
      as practicable.
