Environmental Planning Instrument - Acid Sulfate Soils

This spatial dataset identifies areas of land showing the extent of acid sulfate soils. Acid sulfate soils have been classified into 5 different classes based on the likelihood of the acid sulfate soils being present in particular areas and at certain depths.

  • Class 1: Acid sulfate soils in a class 1 area are likely to be found on and below the natural ground surface.
  • Class 2 : Acid sulfate soils in a class 2 area are likely to be found below the natural ground surface.
  • Class 3: Acid sulfate soils in a class 3 area are likely to be found beyond 1 metre below the natural ground surface.
  • Class 4: Acid sulfate soils in a class 4 area are likely to be found beyond 2 metres below the natural ground surface.
  • Class 5: Acid sulfate soils are not typically found in Class 5 areas. Areas classified as Class 5 are located within 500 metres on adjacent class 1,2,3 or 4 land.
