                                                       Residential buildings minimise risk from flooding by providing
                                                       parking and other low intensive, non-habitable uses at ground         AO6.3 – Not Applicable

                                                       is also encouraged for building works up to the probable
                                                       maximum flood to reduce the consequences of flooding.

                                                       AO6.5
                                                       Basements and underground car parking areas are designed to
                                                       drain and function safely during a flood event and power failure.
