Risk of Flooding from Surface Water Depth: 0.1 percent annual chance

This dataset is not suitable for identifying whether an individual property will flood. GIS layer showing the maximum depth of flooding from surface water that could result from a flood with a 0.1% chance of happening in any given year. The flood depth is grouped into 6 bands. NB: the maximum depth may not happen at the same time as the maximum speed of flow. This dataset is one output of our Risk of Flooding from Surface Water (RoFSW) mapping, previously known as the updated Flood Map for Surface Water (uFMfSW). It is one of a group of datasets previously available as the uFMfSW Complex Package. Further information on using these datasets can be found at the Resource Locator link below. Information Warnings: Risk of Flooding from Surface Water is not to be used at property level. If the Content is displayed in map form to others we recommend it should not be used with basemapping more detailed than 1:10,000 as the data is open to misinterpretation if used as a more detailed scale. Because of the way they have been produced and the fact that they are indicative, the maps are not appropriate to act as the sole evidence for any specific planning or regulatory decision or assessment of risk in relation to flooding at any scale without further supporting studies or evidence.
