7 PREVENTION OF EROSION AND SEDIMENTATION

In order to minimise damage to areas of retained vegetation (within or adjacent to
the subject site), erosion and sediment control measures will be employed
throughout the development phase in accordance with the approved Erosion and
Sediment Control Plans.

Measures to protect vegetation areas from erosion and sedimentation during the
construction phase of the development are outlined below:

i. Erosion & sediment control works shall be undertaken in accordance
with an approved Sediment and Erosion Control Plan. Some issues to
be considered include:

e Minimising the area of disturbance across the development
site;

e Perimeter bunds/cut-off drains designed to by-pass upstream
“clean” runoff around the works area;

e Silt fencing and silt traps established in a manner that will
protect the areas of vegetation to be retained from erosion and
sedimentation; and

e Stabilisation of steep batters/slopes.

ii. As construction activities may impact on retained vegetation areas
(within or adjacent to the subject site) it is important to ensure
sediment fencing is in place before site preparation and other
earthworks commence. Prior to any site preparation operations the
Project Manager (or other suitably qualified personnel) shall undertake
an inspection of all sediment fencing.

iti. Upon completion of earthworks and/or grubbing operations the site is
to be left free draining with no ponding of stormwater within areas of
retained vegetation.

iv. Landscaping works within subject site are to utilise suitable native
locally endemic species where appropriate and in accordance with
approved Landscape Plans.
