Concerned about how flooding can impact your decision? Flood mapping | Business Queensland Council has developed five Flood Planning Areas (FPA) for Brisbane River and creek/waterway flooding to guide future building and development in flood-prone areas. It is important to note that flooding may still present a risk and could include overland flow which will be shown as a Property Development Flag further down the report. The Guide for flood studies and mapping in Queensland (PDF, 2.54MB) promotes a consistent approach to flood studies and mapping throughout the state . Not all maps in this archived site have been captured. The Flood Awareness Mapshows where floods occur now andthelikelihoodor chanceof different-size flood events occurring in the future. The dotted line represents the propertys Indicative Existing Floor Level. Brisbane Flood Maps: Where Are The Flood Zones? - Buildi target: "#hbspt-form-1677930581000-3089810119", This overland flow is generallyunsafe for people, vehicles and buildings, however these hazards are experienced less frequently than in high impact areas. There is a 1 in 20 chance (5% likelihood) of this type of flooding happening in any year. As part of City Plan, a new hazard-based Flood Overlay Code was introduced, to ensure that development adequately considers flooding. The DFL for Brisbane River flooding is a level of 3.7 metres AHD at the Brisbane City Gauge based on a flow of 6800 m3/s. Contains technical information designed for surveyors, builders, certifiers, architects and engineers to help them plan and build in accordance with Council's planning scheme. Note: Flood levels higher than those shown in FloodWise Property Reports can occur in any year, although such flood levels have a lower likelihood than those shown on the report. Are you looking at buying a property? In Australia, this elevation is usually expressed in metres AHD. You can download a Logan Flood Studies map (PDF 3 MB) that shows the extent of the area covered by each flood study. The largest flood of the 20th century occurred in January 1974, rising to a height of 5.45 metres on the Brisbane City Gauge at the river end of Edward Street. This example shows flooding from storm tide. Storm tide flooding is mapped separately. Flood levels may vary significantly across allotments of this size. Is updated more regularly, when a new flood study is adopted by Council. Overlays identify areas within Councils planning scheme that may include constrained land and/or areas sensitive to the effects of development.
