of non-habitable areas;                                   b) for areas where flood modelling is
c) ensure carparking areas can be adequately drained;     available—a minimum of 300mm above
d) ensure drainage does not adversely impact upon         the modelled flood level; and
other premises; and                                       c) for areas where flood modelling is not

impact upon other premises by—                            known flood level;
i. causing ponding on the site or nearby land;
ii. increasing flooding, which adversely affects the      AND
safety or use of any land upstream and downstream;

overland flow path.                                       a) any drainage (including buildings and yards) flows
