e Removing weed species within existing riparian vegetation during the revegetation of
these areas.

As detailed above the western tributary invert will be reshaped, lined with rock in the invert
and revegetated. The justifications for undertaking earthworks in the watercourse are as
follows:

e improve flood storage for the site,

e reduce maintenance requirements,

e remove mosquito breeding habitat, and

e improve drainage from Blue Wren Place which currently ponds.

See Drawing 1225-33 which shows the extent of earthworks in the western tributary plan,
long section, and cross-sections in Figures 9, 10, and 11 of the flood study showing the
minor reshaping of the channel.
