Risk of Flooding from Surface Water

High risk icon This is in an area that has a HIGH chance of flooding from surface water. This means that each year, this area has a chance of flooding of greater than 1 in 30 (3.3%).

Medium risk icon This is an area that has a MEDIUM chance of flooding from surface water. This means that each year, this area has a chance of flooding of between 1 in 100 (1%) and 1 in 30 (3.3%).

Low risk icon This is an area that has a LOW chance of flooding from surface water. This means that each year, this area has a chance of flooding of between 1 in 1000 (0.1%) and 1 in 100 (1%).

Vert low risk icon This is an area that has a VERY LOW chance of flooding from surface water. This means that each year, this area has a chance of flooding of less than 1 in 1000 (0.1%).

Risk of Flooding from Rivers

This is in an area that has a HIGH chance of flooding from rivers. This means that each year, this area has a chance of flooding of greater than 1 in 30 (3.3%).

This is an area that has a MEDIUM chance of flooding from rivers. This means that each year, this area has a chance of flooding of between 1 in 100 (1%) and 1 in 30 (3.3%).

This is an area that has a LOW chance of flooding from rivers. This means that each year, this area has a chance of flooding of between 1 in 1000 (0.1%) and 1 in 100 (1%).

This is an area that has a VERY LOW chance of flooding from rivers. This means that each year, this area has a chance of flooding of less than 1 in 1000 (0.1%).

This map takes into account the effect of any flood defences that may be in this area. Flood defences reduce, but do not completely stop the chance of flooding as they can be overtopped or fail.

Flood Map for Planning

This area could be flooded from a river by a flood that has a 1% (1 in 100) or greater chance of happening each year, if there were no flood defences. For planning and development purposes, this is termed Flood Zone 3.

This area is likely to be affected by a major flood, with up to a 0.1% (1 in 1000) chance of occurring each year. For planning and development purposes, this is termed Flood Zone 2.

This area is unlikely to flood from rivers. There is less than a 0.1% (1 in 1000) chance of flooding occurring each year. For planning and development purposes, this is termed Flood Zone 1.

Flood defences, built to protect against river floods with a 1 per cent (1 in 100) chance of happening each year. (not all will be shown, these are being added gradually through updates).

Areas benefitting from flood defences (not all will be shown, these are being added gradually through updates).

Upper Nene Catchment

Upper Nene catchment within which all drainage design must meet the increased standard of 1 in 200 (0.5%).

Main Rivers

Watercourses designated by the Environment Agency as main rivers. All other watercourses are ordinary watercourses.

Water and Sewerage Companies

Anglian Water

Severn Trent Water

Thames Water

Formal Flood Investigations

Locations where the County Council has undertaken and published a formal investigation of flooding under Section 19 of the Flood and Water Management Act 2010. To view these reports please visit our Flood Investigations Report page.

The maps are intended for guidance, and cannot provide details for individual properties. The maps have been produced by the Environment Agency, using information from Northamptonshire County Council where available/appropriate. You can view this information and more on the Environment Agency's "What's In Your Back Yard" map service.

The Risk of Flooding from Surface Water map shows the areas that are at risk from surface water flooding. If you disagree with the risk of flooding displayed on this map, where you have appropriate evidence (anecdotal evidence alone will not be sufficient), we will review this to see if it can be used to help the Environment Agency update this risk. However, without appropriate evidence, we cannot recommend changes to the map. If you require more information about Evidence Review Requests, please email the Environment Agency’s National Customer Contact Centre at: enquiries@environment-agency.gov.uk
The Risk of Flooding from Rivers map shows the extent and likelihood of flooding from rivers taking into account any flood defences.
The Flood Map for Planning shows Flood Zones without flood defences, as required for land-use planning purposes.

Northamptonshire County Council, supported by ESI Ltd, has undertaken a study to assess the risk of flooding from groundwater across the county. Due to license restrictions we cannot publish these maps in an interactive format on this page, however full details of the study and a PDF document of the map can be found in the Flood Library.
