Is my home in or near a flood risk area?

 

Some areas are more susceptible to flooding than others. This may be because of their location near the coast, rivers or streams. In these areas, the extent of any potential flood area (the 'flood zone') can be mapped quite accurately, using computer modelling techniques.

 

To find out if your address lies in one of these flood zones, visit the Environment Agency web site through the link below, type your postcode or place name into the "Flood Map" box, press the 'GO' button and after viewing the 'Information summary' page you will see a map centred on your postcode, with flood zones coloured in blue. 'Zoom in' on the map for greater detail. The mapping is not accessible to users of accessibility software; details can be obtained by telephone from the Agency's 'Floodline' service on 0845 9881188.

 

If you are proposing to carry out works to a property in a Flood Zone you will often need to consult with the Agency. More details are available on our 'Development and Flood Risk' page.

Please note that whilst the Flood Maps show flood zones for both tidal and fluvial (river) flooding, they are constantly updated as new information becomes available. The maps do not show flooding areas associated with smaller ditches, nor areas likely to be affected by groundwater (springs or spring-like activity) which occur quite extensively in the Havant area due to the underlying chalk geology. For more information about areas susceptible to groundwater flooding, use this link to the Environment Agency's "Groundwater Information Service" instead.
