Driveway Construction:

We note Condition 18 of the REC Approval in relation to driveway construction. The owners
intend to follow Cardno Plan 242001-001 Roadworks Plan and Longitudinal Section & 242001-
002 Driveway Cross Sections both dated 23-3-2012 with minor amendments as follows.

We propose the following surface treatments to reduce construction costs and comply with the
intent of REC Condition 18:

Construct the driveway from CH15-122.9 (steepest section>12%) with:
i. 125mm thick N32 concrete with SL72 mesh (provide 75mm minimum sub-base
pavement under concrete if subgrade CBR value=<6) at 3m width with 0.5m shoulder
on low side (3.5m total width)

The remaining section at CHO-15 will be 150mm thick gravel (to match existing driveway
construction, distance to nearest house is >40m).

We consider that the proposed house site and driveway comply with the intent of
Reconfiguration Approval REC2008/750 and sufficient information has been provided for Council
to approve the Operational Works.

Yours faithfully,
Callaghan & Toth
