A flood is defined as the covering of normally dry land by water that has escaped or been released from the normal confines of a lake, river, creek or other natural watercourse, a reservoir, canal or dam. WHAT IS A FLASH FLOOD? - Flash flooding is localised flooding that occurs when heavy rain cannot drain away quicker than it falls. A flash flood is defined by the speed of flooding, not the source or location of flooding. Flash flooding is typically caused by short duration storms over a localised area or catchment. The Bureau of Meteorology describes flash flooding as "Flooding occurring within about six hours of rain, usually the result of intense local rain and characterised by rapid rises in water-levels." reference A local example of a flash flood is the "supercell" thunderstorm that hit Woden in January 1971 where the Canberra Times reported rainfalls up to 100mm in 1 hour were recorded by private rain gauges in the suburbs of Farrer and Torrens." reference WHAT IS FLOOD RISK? - Flood risk includes both the probability of a flood occurring and the consequences if a flood occurs. The consequences of a flood are in turn affected by the number of people and properties exposed to floodwater and the vulnerability of these people and properties. For example, a river might burst its banks regularly, but if this flooding occurs in an isolated area where there are no people or infrastructure, then the flood risk is considered to be low. Similarly, a river might flood very rarely, but if many people and properties are located near this river and they live in dwellings that are vulnerable to floodwater damage, then the flood risk will be higher. HOW PRONE IS CANBERRA TO FLOODS? - Canberra planning has always taken into account the need to avoid development in flood prone areas. Since the 1970s planning for new urban development in the ACT has kept development above the 1% Annual Exceedance Probability (AEP) flood level. The local storm water system is designed to cope with the 1% AEP storm flows through a combination of piped flows and overland flows. However, no areas are completely immune to flooding. Floods greater than the 1% AEP are possible, and extremely intense local rainfall can cause localised flash flooding. WHAT IS A 1% AEP FLOOD? - The 1% AEP flood is a theoretical flood that is estimated to have has a 1% chance of being equalled or exceeded in any year. For example, if you experienced a 1% AEP flood last year, the chance of experiencing a similar magnitude flood this year is still 1%, regardless of when the previous 1% AEP flood was experienced. The 1% probability is calculated using computer modelling, historic rainfall and runoff records and a range of other assumptions. The value of the 1% AEP is an estimate that will change as the climate changes and as more historic rainfall and flooding information is gathered over time that might change assumptions used in the modelling and estimations. WHAT DOES ACT FLOOD DATA SHOW? - The flood data map shows an estimate of the areas likely to be flooded during a 1% AEP flood - also previously known as the 100 year flood line. The ACT flood map shows flooding extents for riverine flooding only i.e. flooding from named watercourses such as rivers and creeks. WHEN IS ACT FLOOD DATA BEING RELEASED? - The ACT flood data show the 1% AEP flood for the Molonglo River from Yass Road downstream to the Lake Burley Griffin surrounds and further downstream to below Coppins Crossing. There is a program to update flood studies over the next three years for creeks and some major stormwater channels within and adjacent to urban areas. Once these studies are completed, the 1% AEP flood extents will be made available on the ACT Government's ACTMAPi website. DISCLAIMER The ACT Government is providing this flood data for information purposes only. This data is derived from the best available modelling of the catchments and watercourses. The ACT Government cannot and does not guarantee the accu

In the SBMP, Fire Management Zones are identified as a subset of BPAs where measurable fuel management treatments are applied. The location and alignment of these zones reflect the risk of bushfires starting and spreading, and impacting on life, property and other assets. The zones established include Asset Protection Zones, Strategic Firefighting Advantage Zones, Land Management Zones and Rural Land Management Zones. The widths and locations of the Zones shown on this map are indicative and the actual widths and location will be determined in consideration of the ACT Fire Management Standards and operational requirements, through the development of Regional Fire Management Plans and Bushfire Operational Plans (including Farm Firewise). Chapter 11 of the SBMP details considerations used in determining the location and extent of Asset Protection Zones adjacent to new and established urban areas. Fire Management Zoning maps will be reviewed as required to reflect significant changes, which may include unplanned bushfires or changes to the location or extent of assets. The Commissioner is responsible for approval of these maps.
