S8.2.3 Bulk Earthworks and Retaining Walls

Objectives

  1. To allow manipulation of the natural landform whilst preserving distinctive scenic features.
  2. Management of landform manipulation to ensure conditions suitable for development are achieved.

Controls

  1. Development Applications are to provide accurate site surveys prepared by a qualified surveyor to provide a clear and accurate representation of the contours of the land.
  2. Retaining walls at the subdivisional works stage of development are permitted to reduce the need for cut and fill at the dwelling construction stage.
  3. Proposals requiring significant moving and filling of earth will be considered if it contributes to the overall quality of the development and the urban design outcomes for the area.
  4. Development Applications are to illustrate bulk earthworks and retaining walls and provide justification for proposed changes to land levels.
  5. The maximum height of a retaining wall is 1.5 metres.
  6. Any wall with a height of 1.5m or greater requires lodgement of a Development Application.
  7. In instances where a retaining wall greater than 1.5 metres in height is required, a second retaining wall is permitted providing the retaining wall structure incorporates a step of 1 metre in width, with the second retaining wall being limited to 1 metre in height (i.e. first wall a maximum of 1.5 metres and second retaining wall is a maximum of 1 metre).
  8. Retaining walls are to be constructed of masonry materials.
  9. Compaction of filled areas is to be 98% standard compaction and in accordance with AS 3798-1990 in accordance with engineering standards and a compaction certificate is to be submitted to Council.
  10. Earth moved from areas containing noxious weed material must be disposed of at an approved waste management facility and transported in compliance with the Noxious Weed Act 1993.
