            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
            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.
            COUNCIL ACCEPTS NO RESPONSIBILITY FOR THE ACCURACY OF THIS INFORMATION
            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.

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

                                           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.
                                           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.

                                           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
