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 rare.
The absence of flood information does not imply that the above property is not subject to flooding, simply that Council has no
flood information for this property flooding.
If there is a history of flooding or drainage issues we recommend you seek professional advice on this matter.
SUNSHINE COAST COUNCIL ACCEPTS NO RESPONSIBILITY FOR THE ACCURACY OF THIS INFORMATION

GLOSSARY OF TERMS
            Term                                                         Definition
Applicant                      The individual/s requesting a flood search to be completed for a specified property.
                               The individual/s that are registered by Council as owning the property for which a flood
Registered Owners
                               search is requested.
                               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 Average Recurrence Interval (ARI) is a statistical estimate of the average period in
                               years between the occurrence of a flood of a given size or larger.
ARI
                               For example the 100 year ARI event will occur on average once every 100 years, this is
                               equivalent to a 100 year ARI having a 1% probability of occurring in any given year.

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

Location Description of
                               A description of the site where the Highest Historical Flood Level was recorded.
Recorded Historical Event
Date of Historical Event       The date on which the Highest Historical Flood Level occurred.
                               The minimum floor level calculated in accordance with the Town Plan through the addition
Minimum Floor Level            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.
                               Where a ‘regulation line’ has been set by Council to define the limit to which development
Flood Regulation Line
                               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.
                               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
                               The elevation of water generated by a tropical cyclone above or below the normal

                               A tropical cyclone is a low-pressure system which develops in the tropics and is sufficiently

                               km/h near the centre.
                               A factor of safety usually expressed as a height above the adopted Defined Flood Level. A
