interchange with access provided to and from the Highway and to Cooroy adjacent to and north
of the highway. The interchange has been previously upgraded to accommodate local traffic as
well as the traffic generated from the timber mill which formerly operated on the site. Detailed
discussions relating to the access infrastructure have been included in the LSA Traffic

Assessment.

Electricity and Telecommunications

An above ground power line extends across the southern portion of the site, with a small
auxiliary line extending to the north-west to the existing building. The primary line supports a
33kV supply with a lower voltage (11kV) line also present. Preliminary investigations suggest
that the development of the site will require the relocation of the majority of this line along the
rear of the development, running within and parallel to the proposed parkland to be dedicated as
a vegetation buffer. An easement will need to be declared over the alignment of the underground

power line in favour of Energex (where not located within a road reserve).

A pad mounted transformer will be required to convert power from the 11kV line to required
consumer needs (possibly 415Vand 240V) to service the 6 allotments as Energex are unlikely to
permit connection to the 33kV line. This transformer may be located adjacent to the new cul-de-
sac on proposed Lot 6. The service will be extended from existing lines within the Holts Road

reserve to the new transformer along the cul-de-sac.

Drainage Infrastructure

Holts Road is serviced by a well constructed table drain located between the road pavement and

the property boundary. A 300mm dia. RCP extends across the existing site access.

Some diversion bunds, drainage swales and dams exist on site. The dams are likely to have been
installed as a method of improving water quality by retaining sediment during storm events, with
well defined entry points, etc observable during site inspections. The dams also have some
retention capacity, in particular the dam in the south-eastern corner of the site which has a
concrete overflow spillway. No other significant drainage infrastructure exists on the property. A
detailed Stormwater Drainage Assessment Report has been prepared by LSA to accompany this

application.
