Note 1: A geotechnical / hydrogeological report may be required to<br />

demonstrate this.<br />

Note 2: If the ground level is modifi ed within the canopy spread, an<br />

arborist’s report will be required to assess the impact of the proposed<br />

works. Refer to AS4970:2009 Protection of trees on development sites.<br />

or concentrate stormwater or surface water runoff onto adjoining<br />

properties.<br />

subsurface/groundwater flows or direction on groundwater<br />

dependent ecosystems or species.<br />

Note: Riparian systems and a number of vegetation communities or species<br />

may be fully or partially dependent on subsurface/groundwater fl ows. A<br />

hydrogeological report may be required to address changes to groundwater.<br />
