5.0 EARTHWORKS
There will be earthworks required to facilitate construction of stormwater treatment facilities, sanitary
drainage and allow for an aesthetically pleasing and functional built form. There is little opportunity
for fill material to be won on site therefore most of the fill material will need to be imported.

The interface with the western boundary to the Council reserve will require approximately 2.0m of fill
to be placed. Preliminary Geotechnical reports indicate the subgrade material in this area is of very
poor quality and will likely cause issues with either a gravity or cantilevered retaining wall solution. It
is proposed that a stabilised batter into the Council Reserve would provide a better long term solution
at this interface.

In addition to the geotechnical challenges of retaining at this interface, a stabilised batter solution
would be more appropriate for the following reasons:
       Would provide safer and easier access to the council reserve.
       Safer from a vehicular and pedestrian perspective.
       More aesthetically pleasing.
       May add to fire buffering of buildings.
       If revegetated with native plant species would enhance the environmental qualities of the council
        reserve.

This area within the proposed footprint of the batter is already cleared therefore would result in very
little disturbance. Any solution would be subject to Geotechnical investigation and advice to
determine appropriate treatment. The photograph below (Figure 6), illustrates the ‘swampy’ nature
of the lower area of the site.
