Part 7 Clause 7.2
7.2   Earthworks
(1)  The objective of this clause is to ensure that earthworks for which development consent is required will not have a detrimental impact on environmental functions and processes, neighbouring uses, cultural or heritage items or features of the surrounding land.
(2)  Development consent is required for earthworks unless—

(b)  the earthworks are ancillary to development that is permitted without consent under this Plan or to development for which development consent has been given.
(3)  Before granting development consent for earthworks (or for development involving ancillary earthworks), the consent authority must consider the following matters—
(a)  the likely disruption of, or any detrimental effect on, drainage patterns and soil stability in the locality of the development,
(b)  the effect of the development on the likely future use or redevelopment of the land,
(c)  the quality of the fill or the soil to be excavated, or both,
(d)  the effect of the development on the existing and likely amenity of adjoining properties,
(e)  the source of any fill material and the destination of any excavated material,
(f)  the likelihood of disturbing relics,
(g)  the proximity to, and potential for adverse impacts on, any waterway, drinking water catchment or environmentally sensitive area,
(h)  any appropriate measures proposed to avoid, minimise or mitigate the impacts of the development,
(i)  the proximity to, and potential for adverse impacts on, any heritage item, archaeological site, or heritage conservation area.
