Flooding damage to houses in the Flockton Basin area in early March would probably have been avoided if floor levels were nearly half a metre higher.
This is one of the findings of scientific modelling through Riskscape carried out by NIWA. The software took data from photos supplied by residents and information from technicians called out to deal with flooding.
According to the modelling, there would have been no house-related damage if the floors were 45cm higher. A rise of 10cm would have reduced the costs of damage by half. The flooding in the Flockton Basin has been estimated at $2.2million (including contents).
