Find out more information about floor levels at your property using this map:

Using the map
Select the layers on the left that you want to view
Use the Point Identify tool to select an address within the map
Zoom in till you can see the black dots on the properties; then with the Point Identity tool selected, click the dot on the property of interest - or...
... Search for an address in the search box at the top right of the map.
Hint – enter a street address such as 36 Streetname and not 36 Streetname Street.
Click on the floor level point found at the left side of the map and the following information will be provided:
- Interim Floor Level – the minimum floor level for a new building or if significant extensions are required. This level may be subject to review as a result of new catchment modelling or a specific site assessment and is not necessarily the exact level that would be used for a consent. Refer to Floor Level Requirements for further information.
- Mean Ground Level – average ground level on the site as determined by the latest ground surface information.
- Min Ground Level – minimum ground level on the site as determined by the latest ground surface information.
- Max Ground Level – maximum ground level on the site as determined by the latest ground surface information.
- Floor Level Control Area (50 year) - area within and adjacent to the 50 year flood extent. The Council applies a 400mm freeboard above modelled water levels to set floor levels in this area.
- Flood extent (50 year) – estimated water level in a rainfall event with an average return interval of 50 years or a likelihood of 1/50 (=2%) in any one year.
- Flood extent (200 year) – estimated water level in a rainfall event with an average return interval of 200 years or a likelihood of 1/200 (=0.5%) in any one year. This return interval is used in the District Plan Flood Management Areas (FMA) to provide extra protection to areas which are otherwise vulnerable. The viewer shows these areas within the FMA only as they are not used for setting floor levels beyond the FMA.
- Water levels and ground levels - are expressed in metres above the Council’s datum level. This datum level is about nine metres below Mean Sea Level. So a level of 10m above the Council’s datum is about one metre above Mean Sea Level.
If your property is visible when you view the map on the website and no floor level information is available, then it is unlikely that any specific floor level will be required at the time of the consent. Standard Building Code clearances above surrounding ground will still apply.
If your property is shown as greyed out on the map on the website, the latest modelling information is still being processed and you should contact email@example.com for this specific information.
