# APL Flood Zone Map

The Flood Map indicates the extent of river flooding associated with a flood event having a 1% chance of occurring in any year (1 in 100-year event) and the extent of coastal flooding for the extreme sea level having a 0.5% chance of occurring in any year (1 in 200-year event). In both cases the potential effects of climate change on flood magnitudes are accounted for (by assuming a 20% increase in peak river flows, and taking into consideration the predicted degree of sea level rise based on a 2119 time horizon).

The Flood Map indicates where formal flood defences and flood alleviation schemes are in place, and the mapped extents of flooding reflect the influence of flood detemors on flood risk. However, defence structures may not completely remove the risk of flooding in extreme events. It should also be noted that defences can be breached or fail in extreme weather conditions, and coastal defences can be overlapped by large waves. These additional risk factors are not considered in the Flood Map.

The information provided is not an at resolution appropriate for localised flood risk assessments and should not be assumed as definitive at the property scale. Individual properties may, therefore, not always be at the same risk of flooding as surrounding areas/properties. If you believe that a particular property has a different risk of flooding to that shown on the Flood Map and/or if you have information you believe may not have taken into account when preparing the Flood Map please contact Mans Utilities. As and when additional relevant information becomes available to Mans Utilities, the Flood Map will be improved and updated.

Mans Utilities reserve at Intellectual property rights associated with the Flood Map. Mans Utilities believe that the Flood Map, and information contained therein, accords with the information currently available to it, but no representations or warranties (express or implied) are given with regard to its accuracy. To the fullest extent permitted by law Mans Utilities will not accept liability for any losses resulting in conviction with the Flood Map.
