Stormwater management
6.7 Stormwater management
The objectives of this clause are as follows—
to minimise the impacts of urban stormwater on properties, native vegetation and receiving waters,
to avoid adverse impacts on soils and land stability,
to protect the environmental values of water identified for urban waterways in the Sydney Harbour and Parramatta River and Georges River catchments.
Development consent must not be granted to development on land to which this clause applies unless the consent authority is satisfied that the development—
is designed to maximise the use of water permeable surfaces on the land having regard to the soil characteristics affecting on-site infiltration of water, and
includes, if practicable, on-site stormwater retention for use as an alternative supply to mains water, groundwater or river water, and
avoids significant adverse impacts of stormwater runoff on adjoining properties, native bushland and receiving waters, or if the impact cannot be reasonably avoided, minimises and mitigates the impact.
