8.0 EARTHWORKS

An earthworks management plan will be prepared for the proposed development with a view to
minimise the construction impact on the surrounding environment. The intent is to generally
avoid earthworks that.exceed a depth of 0.5m provided that this will not apply to the
construction of car parks, water supply and sewerage, swimming pools and water bodies
generaily.

The proposed eco-cabins will be constructed using techniques that require minimal excavation.
The final location of the proposed eco-cabins will be determined based on minimal impact with
existing vegetation (ie position around existing trees).

The construction of the proposed road network servicing the eco-cabins will also be carried out
adopting construction methodologies that will minimise the need for significant earthworks. It is
proposed that the access ways be constructed with one way cross fall that will ensure minimal
earthworks requirement (given the natural topography of the land) and will also assist in the
stormwater management process.

A site slope analysis was carried out to identify any problematic site slope stability areas. Figure
9 provides a graphical illustration of the various grades that exist in the area. This figure
demonstrates that there are minimal areas that exhibit site grades of greater than 20%.
Locations selected forthe eco-cabins, the proposed lodge and associated facilities exhibit site
grades between 5%-15%.

The final location of the proposed major buildings, which will incorporate the lodge, interpretive
centre and café, will be selected based on the objective of minimisation of earthworks.
