Flood level approval is a process to check that anyone planning to build or renovate a property has considered their flood risk.
You must apply for flood level approval if:
- your property is at risk of flooding
- it's a condition of your planning permit
- a report and consent matter affects your building plans
- a consultant, architect, builder, or building surveyor asks you to.
Use our online form:
The assessment fee is $255.50. The fee does not incur GST.
You must include a survey plan that shows levels for the:
- nature strip
- kerb and channel
- drainage pits.
You must include floor plans that show:
- ground and basement levels
- vehicle and pedestrian entries
- any other possible location where flood water could enter the building.
You can request a flood assessment report with advice about the flood risk to your property.
Visit our Building or developing on flood-prone land page to get your report.
Assessing your plans
We assess your plans within 20 business days.
We will check that the proposed development:
- has a finished floor level above the identified flood level with 300 mm extra height (freeboard)
- is set back from overland flow paths (the paths that take the main flow of floodwater).
If you need to make changes you can resubmit your plans to [email protected].
