DISCLAIMERS

Flood information provided by Council should only be used as a guide to the extent of flooding on the property. This
information may be inaccurate or incomplete and it is recommended that purchasers make their own local enquiries with
regard to the flooding and drainage history of the site. NO LIABILITY IS ACCEPTED FOR THIS INFORMATION.

The property information supplied does not represent the highest probable flood level that could occur on this property. A flood
more severe than the level described above may occur, although such events would be extraordinary.

The absence of flood information does not imply that the above property is not subject to flooding, simply that Council has no

GLOSSARY OF TERMS
Term Definition

The Australian Height Datum (AHD) is the reference level for defining reduced levels

AHD adopted by the National Mapping Council of Australia. The level of 0.0 m AHD is
approximately mean sea level.

Defined Flood Level A water level derived through mathematical modelling of the Defined Flood Event.
Terminology consistent with State Planning Policy (SPP, 2003) which states “Defined Flood

Defined Flood Event Event is the flood event adopted by a local government for the management of development
in a particular locality”.
The Annual Exceedance Probability is the likelihood of occurrence of a flood or storm tide
inundation event of a given size or larger in any one year, usually expressed as a
percentage. For example, if an event has an AEP of 1%, it means that there is a 1% risk

1% AEP. (i.e. probability of 0.01 or a likelihood of 1 in 100) of this event occurring in any one year. A

1% AEP event should not be interpreted as only occurring once in 100 years.

This flood event is also commonly called the 100 year ARI (Average Recurrence Interval) or
Q100.

 

Source of Information

Is a reference to the document summarising the results of the anticipated flooding relevant
to this location.

 

Highest Historical Flood
Level

The highest flood water level from all historic events for which Council has records.

 

Location Description of
Recorded Historical Event

A description of the site where the Highest Historical Flood Level was recorded.

 

Date of Historical Event

The date on which the Highest Historical Flood Level occurred.

 

Minimum Floor Level

The minimum floor level calculated in accordance with the Town Plan through the addition
of the relevant freeboard to the Defined Flood Level and the Highest Historical Flood Level.
Council requires that the higher of these two levels be used as the minimum floor level.

 

A factor of safety usually expressed as a height above the adopted Defined Flood Level. A

 

Freeboard freeboard tends to compensate for factors such as wave action and historical and modelling
uncertainties.
i ial situation: a livi i F I m, dini m,
Habitable Room/Area In a residential situation: a living or working area, such as a lounge roo ining root

rumpus room, kitchen, bedroom or workroom.

 

Flood Regulation Line

Where a ‘regulation line’ has been set by Council to define the limit to which development
may encroach onto a floodplain, development is undertaken outside such ‘regulation line’.

 

Rainfall Intensity

The amount of rainfall occurring in a unit of time, usually expressed in millimetres/hour.

 

Mean Sea Level

A tidal datum; the arithmetic mean of hourly heights of the sea at the tidal station observed
over a period of time (preferably 19 years). Source: BOM This is approximately 0.0 m AHD

 

Storm Surge

The elevation of water generated by a tropical cyclone above or below the normal
astronomical tide.

 

 

Tropical Cyclones

 

A tropical cyclone is a low-pressure system which develops in the tropics and is sufficiently
intense to produce sustained winds of at least 63 km/h or greater and gusts in excess of 90
km/h near the centre.
