> Electricity and water supply for the sewer pump station;
> Stormwater drainage pipelines; and

> General access slope to accommodate 1 in 100 year overflows.

The traffic assessment prepared by LSA for this development indicates that the existing road
transport infrastructure in the vicinity of the site is of sufficient capacity to accommodate any
additional traffic generated by the proposal. Details relating to the calculation of intersection
capacity and possible traffic volumes over a ten year time horizon have been included in the

Traffic Assessment Report.
WATER SUPPLY AND SEWERAGE

Water Supply

The existing water main extending from Council’s reticulated water supply and servicing the site
will require upgrading as part of the proposed development. Council’s records indicate that the
pipework is a non-standard size (approximately 65mm dia.) that was laid in the 1970s. The pipe
comprises old polyethylene that has greatly deteriorated and Council has confirmed that the
pipeline is expensive to maintain given the cost of non-standard fittings and the continuing

deterioration issues.

The alignment of the water main extends south along Myall Street from a 200mm dia main in
Ferrells Road. The pipeline is contained in the Myall Street reserve and crosses under the Bruce
Highway to Holts Road near the existing entrance to the development site. The exact location of
the highway crossing and its connection point at the site frontage is not known. The pipeline is
approximately 900 metres to 1 kilometre in length from the Ferrells Road connection point to the

site.

The capacity of the current system is low. The main reservoir is situated toward the opposite side
of town, with a top water level of 157.90 metres. The residual peak hour pressure at the
connection point on Ferrells Road is 29.08 metres at an elevation of 116 metres. As the site

extends to approximately 125 metres AHD, the static loss is in the order of 9 metres. Initial
