9.4.2.2          Purpose and Overall Outcomes
(1)   The purpose of the Earthworks code is to ensure earthworks do not unreasonably impact on the natural environment or
      other properties and provide a safe and secure work environment.
(2)   The overall outcomes sought for the Earthworks code are:
      (a)   Earthworks are designed and constructed to be structurally sound.
      (b)   All onsite works provide land stability (including differential settlement or expansion in reactive soils).
      (c)   Earthworks avoid contamination of land.
      (d)   Flooding and drainage are appropriately addressed.
      (e)   Groundwater, watercourses and wetlands are protected.
      (f)   The loss of native remnant or regrowth vegetation is avoided.
