Flood — Awareness — Flood Risk Overall

This dataset, created in June 2013, provides an indication of the likelihood of a flood occurring from one or more sources: creek, river, and storm tide inside the Brisbane City Council local government area. This layer contributes to the overall Flood Awareness Mapping for Brisbane City Council.Brisbane City Council has developed the Flood Awareness Maps and adopted the terms ‘high’, ‘medium’, ‘low’ and ‘very low’ likelihood areas to help residents and businesses better understand the likelihood of a flood affecting their property. The Flood Awareness Maps are an awareness tool and the maps do not provide information about the depth or speed of flood water. Information on potential flood levels for a property can be found in the FloodWise Property Report online.The Flood Awareness Maps are an awareness tool to provide an indication of the likelihood of a flood occurring from one or more sources: creek, river, overland flow and storm tide. The maps do not provide information about the depth or speed of flood water. Use the FloodWise Property Report for information about flood levels specific to your property.Many properties within the high and medium flood likelihood were affected by flooding in the 1974 and 2011 Brisbane River floods.Residents in the low and very low flood likelihood areas should still be aware of their risk of flooding and understand how they, as well as others in the area, may be affected.High likelihood areaFlooding is almost certain to occur in a high likelihood area. Residents and businesses are strongly advised to learn about the flood likelihood for their property so they can be prepared to help minimise the impact on their home, business and family.Medium likelihood areaFlooding is likely to occur in a medium likelihood area. Residents and businesses are advised to learn about the flood likelihood for their property so they can be prepared to help minimise the impact on their home, business and family.Low likelihood areaLow flood likelihood areas may experience flooding in a rare flood event. Residents and businesses should consider how flooding may affect their local area, suburb or community. Flooding is unlikely in a low flood likelihood area but it may still occur.Very low likelihood areaVery low likelihood areas are unlikely to flood except in a very rare or extreme flood event. Residents and businesses should consider how flooding may affect their local suburb, area or community. Flooding is very unlikely in a very low flood likelihood area, but may still occur.Brisbane City Council is working hard to reduce the impact of flooding but we all have a responsibility to understand our flood risk and be better prepared to minimise the impact of flooding on our homes, property and businesses.

本数据集创建于2013年6月，用于评估布里斯班市议会（Brisbane City Council）地方政府辖区内，由溪流、河流及风暴潮等一种或多种来源引发洪水的发生概率。该图层是布里斯班市议会整体洪水意识地图（Flood Awareness Mapping）的组成部分。
布里斯班市议会已编制洪水意识地图（Flood Awareness Maps），并采用“高”“中”“低”“极低”四个概率等级，帮助居民与企业更清晰地了解自家或商铺遭遇洪水影响的概率。此类洪水意识地图仅为认知辅助工具，不提供洪水水深与流速相关信息。特定物业的潜在洪水水位信息，可通过在线FloodWise物业报告（FloodWise Property Report）查询。
洪水意识地图可用于评估由溪流、河流、坡面径流（overland flow）及风暴潮等一种或多种来源引发洪水的发生概率。此类地图不提供洪水水深与流速相关信息。如需查询针对特定物业的洪水水位信息，请使用FloodWise物业报告。
1974年与2011年的布里斯班河洪水已对诸多处于高、中等洪水概率区域的物业造成影响。
处于低、极低洪水概率区域的居民仍需警惕洪水风险，并了解自身及所在区域其他人群可能受到的影响。
高概率区域：高概率区域几乎肯定会发生洪水。强烈建议居民与企业了解自家物业的洪水概率情况，以便做好准备，最大限度降低洪水对住宅、商铺及家庭的影响。
中概率区域：中概率区域可能发生洪水。建议居民与企业了解自家物业的洪水概率情况，以便做好准备，最大限度降低洪水对住宅、商铺及家庭的影响。
低概率区域：低概率区域仅在罕见洪水事件中可能遭遇洪水。居民与企业应了解洪水可能对所在街区、郊区或社区造成的影响。低概率区域发生洪水的可能性较低，但仍有可能发生。
极低概率区域：极低概率区域仅在极罕见或极端洪水事件中可能遭遇洪水。居民与企业应了解洪水可能对所在街区、郊区或社区造成的影响。极低概率区域发生洪水的可能性极低，但仍有可能发生。
布里斯班市议会正全力降低洪水带来的影响，但我们每个人都有责任了解自身的洪水风险，并做好更充分的准备，以最大限度减轻洪水对住宅、物业及商铺的影响。如需获取更多信息，请参阅议会官方网站。
