Item 7: Detail any amenity impacts on neighbouring properties.

Applicant’s Response to Item 7: Item 7 comments that the proposed works include significant fill with
retaining walls along most boundaries of the subject properties and requests details of impacts on
neighbouring properties. As detailed in Attachment B the retaining wall and fence will have a typical
height of 2.8 metres which includes 900mm of fill required for minimum floor heights and screen
fencing typical for the area. The 900mm of fill required on the site is to comply with Councils minimum
floor height requirements for flooding and the fencing required for safety and privacy.

The fencing and fill has been engineered to address stormwater drainage on site and on adjoining
premises whilst providing privacy for the development and surrounding sites. An extract of the
proposed fencing and fill details is provided below.
