(2) The Valuer General obviously considered the potentiality to flooding to be
highly relevant, for the very reason that it affected land value. There is clear
evidence in the Determinations themselves and in the files indicating that this
was recognised as a relevant factor. For example, Mr Lynar discussed with David
Kettle, who was the landowners' planning consultant the extent and cause of
flooding potential and the possibilities, cost and feasibility of raising the land. Mr
Kettle was asserting that 27 building blocks could be created on lot 2 above the
1% flood line. Mr Lynar queried the accuracy of the Flood Report with its
principal author, Mr Dewar of Webb, McKeown & Associates and apparently
obtained both oral and written acknowledgment from him that some of the land
on lot 2 could be above the 1/100 year flood level, or at least less than 0.5m below
it. It is obvious from file notes and correspondence that there was a real issue
about the accuracy of the Flood Study, as well as the possibility that its
conclusions about the subject land could be avoided by filling the land and/or
some waiver of Council policy adopting the 1% AEP flood as the designated
flood. Representatives of both "sides" interviewed by Mr Lynar suggested that
the truth of the contour levels would only be known for certain if a survey was
commissioned. Indeed one was, for lot 2, and the survey (dated 16 August 1994)
made its way into the Valuer General's files. Its interpretation was not the subject
of any submission in the appeal. However, handwritten markings on the survey
suggest that it was interpreted as disclosing that some of lot 2 was above 1/100
year flood contour. The possibility of a detention basin being constructed as a
means of alleviating the flood risk was also discussed by Mr Lynar with a Council
officer.
