Technical Note in response to action notice

                                                                    Ref No 20648-R1 – Rev 2




The access was assessed for sight distance requirements. Turpentine Road does
not have a posted speed limit but other streets in this area such as Illoura Place have
a 60kph speed limit. Based on the road geometry (road width and horizontal
alignment) and observations of actual traffic using the road, it is our opinion that
60kph is a reasonable estimation of the speed environment. The visibility to the south
was measured as being over 200m to the south which exceeds the minimum
requirement for 60kph speed limit of 123m (and would exceed the requirements for
80 kph). The visibility to the north was restricted by the horizontal bend in the road
to only 60m, however given that Turpentine Road is a dead-end street, vehicles
exiting the property will virtually never turn to the right meaning sight distance to the
left is not critical for the safe operation of the driveway. It is noted that a similar sight
distance would apply for the existing access on the neighbouring property to the
south.

CONCLUSION & CERTIFICATION

In conclusion I certify that the secondary dwelling constructed at 22 Turpentine Road
is constructed well above local flood levels and does not cause additional ponding
of stormwater on any adjoining properties.

In addition, although the access to the property that services the second dwelling
does not fully comply with Council standard drawing RS-065 it is deemed to be a
suitable and safe access, constructed to a standard that is suitable for ongoing use
and is consistent with or exceeds the standard of other accesses on this road. As
such we request Council consider this report to be an Operational Works Application
to allow the driveway to be retained and continue to be used by the owners to access
their dwelling at 22 Turpentine Road, Ringtail Creek.
