Building in flood prone areas
Duty Planning and Building Officer Service Update.
Until further notice our regular Duty Planning and Building Officer service continues to be available via phone, Zoom, Teams and email. Our Duty Officers can be contacted on 8416 6333 or firstname.lastname@example.org. Face-to-face enquiries at our Development Desk at the Civic Centre are only available on a 'by prior appointment' basis. We apologise for any inconvenience.
If you're planning to build in an area that could be affected by flood in a major storm there are conditions which must be met.
Your application will be considered on merit, with consideration given to the nature of the land you plan to develop and the form of development you propose.
In most cases the ground floor level of new developments needs to be built 200mm above the level of floodwaters occurring during a 1-in-100-year storm event.
Before designing a new building or a building extension, contact us to determine the requirements for your property.
A 1-in-100-year storm event
A 1-in-100-year storm event is a storm which causes higher than average flooding and has a one per cent chance of striking in any given year.
This doesn’t mean that one only occurs every 100 years - floods can happen any time.
