Our flood records

The Flood Strategy will be based on an assessment of current and future flood risk. This assessment takes a range of available data sources and presents the information as a series of maps. These maps, and the analysis of the data, are the starting point for the strategy - they help to identify the locations where action is required to tackle flooding issues.  

The main sources of data for the assessment are:

• A database of flood events that has been kept by Hampshire County Council recording events reported by members of the public and local officers. This records flood events that occurred within the last five years and other significant events that have occurred historically. Information relating to each of these events such as cause, consequence and frequency is recorded in addition to the location of flooding. This shows where flooding has occurred.
• The Flood Map for Surface Water provided by the Environment Agency. This shows modelled flood outlines and indicates areas with a 1 in 30 and 1 in 200 chance of surface water flooding. This shows where flooding might occur.

A key part of the Local Flood Risk Management Strategy is the assessment of current and future flood risk. A series of maps have been produced to show different types of flooding and flood risk.

This data has been displayed in seven maps covering the Local Authority Areas:

• Basingstoke and Deane  2mb
• East Hampshire  2mb
• Eastleigh, Fareham, Gosport and Havant  1mb
• Hart and Rushmoor  2mb
• New Forest  1mb
• Test Valley  2mb
• Winchester  2mb
