 For reconfiguring a lot or operational works, development        In the Flood Hazard Overlay, or in areas otherwise
 does not directly, indirectly or cumulatively alter the flood    determined to be subject to the DFE or DSTE,
 characteristics external to the development site for all         development ensures:
 flooding and inundation events up to and including                        1. there is no loss of on-site flood storage
 the DFE or DSTE based on:

 Development ensures that building design and building form:      level and the levels of adjoining properties to facilitate
          1. accounts for potential flood risk;                   pedestrian flows and visual and physical connectivity
          2. is resilient to flood events; and                    between the footpath and ground floors.
