Hi Mike
Further to our meeting in relation to the proposed logging of pine trees on the northern slopes directly
below the observatory on Kaiti Hill, in my opinion there are unlikely to be any geotechnical issues of
significance to address in relation to the felling of trees beyond that which would need to be addressed
for any steeply sloping terrane. This conclusion is drawn from our extensive knowledge of the
engineering geology of Kaiti Hill and the variations of the geotechnical performance of the slopes
forming it from several deep level geotechnical investigations for repairs to the road and also from
numerous walkovers of the hill, including the subject catchment proposed to be logged.
Kind regards,
Georg Winkler
