Technical Note in response to action notice

                                                               Ref No 20648-R1 – Rev 2




The subject dwelling is located on land with a surface level of approx. RL 10.5
according to the aerial contours – refer to the image below. This is well above any
known flood level in the area. It should also be noted that existing dwellings to the
east of the subject dwelling are sited on ground much lower than this.

In addition, the new dwelling has been constructed approximately 500mm above
existing ground levels – refer photos on the following pages.

In regard to the overland flow paths. The general lay of the land falls from the south
west to the north east. As part of the construction for the secondary dwelling the
owners have constructed an open drain within their property to collect the overland
flows and direct these to Turpentine Road to the east. Refer marked up image below
and site photos. As such the new dwelling does not cause additional ponding of
stormwater on any adjacent property.
