Solution to the flooding problem

[harm_less]

In the Edcumbe  floods it was  found majority of properties that suffered flood damage were  on flat concrete    plinth  .  Its  cheap  &easy to build    which makes it popular  .Personally ive never lived in one  always prefered  it to be at least  3-400 mm off the ground  .Insurance  companies are looking at higher premiums for  houses built  on flat  plinth

Concrete plinth floors also fare far worse in earthquakes I would imagine, with what damage that does occur being far more problematic to repair.
