4. Earthworks and Stormwater Management

As discussed at our meeting with Barlow Shelley at your office on Tuesday 26 November, there are
existing fixed levels on the site and immediately adjoining infrastructure that we are working to. These are:

e the Walter Hay Drive roundabout in the east at approximately RL 8;

e the level of the eastern end of the existing Hofmann Drive pavement at approximately RL4.0, and

e the level of the open space at the southern boundary of the site which varies from approximately
RL2.5 to RL3.6.

Necessarily, the southern lots require some fill to ensure that they are suitable for development and that
stormwater treatment can be undertaken within the lot prior to discharge in the open space. We have
minimised the extent of earthworks across the site. Some of the fill will be sourced from onsite particularly
Lots 2,5,6,8,9,10 and 16. The balance fill will be imported.

The amended plans attached depict:

- the extent of cut and fill including natural surface levels and finished levels (including in southern
lots 10-16);

- the proposed works within the bushfire setback of Lots 11-15, including hardstand and batter within
the lots;

- the extent of the proposed roadworks and pedestrian and cycle infrastructure; and

- the current survey plan as an underlay including the proposed pedestrian easement to the western
boundary of Lots 3 and 4.

The revised Stormwater Management Plan (SWMP) shows the indicative locations of bioretention devices
to maintain environmental habitat within covenant and open space areas, along with the typical section of
the proposed bioretention treatment (refer drawing SW07).

5. Vegetation Removal

We refer to the revised clearing plan and current aerial photo of the site provided at Attachment 6. The
extent of retained vegetation is dictated by the necessary civil works to deliver the lots and associated
services, including stormwater management, as well as road infrastructure. We have retained vegetation
where possible to lots to allow a park like setting for the ultimate development to be maintained.

As discussed at our workshop on 19 November, we are substantially retaining existing vegetation in Lots 3
and 7 until planning for the Village Mixed Use precinct has been completed and a future Development
Approval is obtained. We will undertake interim 10 metre clear fire break clearing within Lots 3 and 7 along
the southern boundary to provide a bushfire setback for Lots 4, 5, 6, 8 and 9. The existing 10 metre fire
break along the eastern side of Covenant J will be maintained. Clearing will be required to deliver the new
roundabouts and the North South Link road. Following the completion of the ROL works, Noosa Civic will
necessarily prepare a revised Bushfire Management Plan which will maintain these fire breaks on an
ongoing basis until Lot 3 is developed.

As discussed and agreed at our meeting on 19 November, Lot 23 is no longer proposed to be cleared —
any clearing will form part of a future Development Application.

We have revised the extent of clearing works in response to our detailed work regarding the extent of cut
and fill on the site as depicted on the revised civil documentation.

In respect of Lots 17-19, we are retaining 6 metres of vegetation to the rear of these lots. This will also
assist in providing a buffer to the rear of the Big W store at Noosa Civic, as well as the loading dock. Given
the current site levels and the need to provide appropriate stormwater management for these lots, we are
unable to retain the vegetation to Lot 17, 18 and part of Lot 19 fronting Hofmann Drive. We will be able to
retain a 6 metre wide vegetation strip to the front of Lot 21 and part of Lot 19, which is shown on the
attached plan.
