In December 2014 Cabinet approved a shift in approach to look at a more holistic and joined up approach to managing flood risk. This approach seeks to provide a more joined up and integrated approach to flood risk management by all authorities, agencies and communities. In September 2015 a progress report was reviewed by the ETE Select Committee on this approach and what this means in relation to next steps.
The catchment approach:
- aims to look at a whole river catchment, or sub-catchment and identify areas that are at risk and that have experienced flooding in recent events
- provides an understanding of how the catchment floods, which has not been based on administrative boundaries or flooding sources
- It makes clear that, when considering flood risk measures, there are likely to be a range of measures and options of varying in size, scale and complexity that may be appropriate
- Acknowledges that a number of authorities, agencies and communities need to come together to mitigate future flood risk
Work is currently underway on the Test and Itchen Catchment plans as theses were undertaken as pilot schemes following the flooding in 2013/2014.
Surface Water Management Plans (SWMPs) and Groundwater Management Plan
Previously the County Council has prepared Surface Water Management Plans (SWMP). The plan takes into account the risks posed by surface water flooding, including agreement about who will do what to better manage these risks.
Draft Surface Water Management plans are available for Rushmoor and Eastleigh.
The draft Surface Water Management Plan focuses on surface water flood risk in the borough. It describes the significant features which can impact on surface water flood risk. It collates and assesses historic data on surface water flood events in Rushmoor and uses Defra / Environment Agency mapping data and projections to determine likely future flood risk taking into account the impacts of climate change.
This data is described and assessed by Ward looking at each area’s susceptibility to flooding based on information from past flood events and the likelihood of future flooding based on national modelling data.

This data is described and assessed by Parish (including the un-parished area of Eastleigh town itself) looking at each area’s susceptibility to flooding based on information from past flood events and the likelihood of future flooding based on national modelling data.

The plans allow a hierarchy of flood risk in the borough to be identified along with surface water flooding ‘hotspots’ where further, more detailed work may be required into the causes of, and possible responses to, flood risk.
It highlights what solutions may be required to manage flood risk in those ‘hotspot’ areas and where further investigation is recommended.
Some flood risk management responses are proposed in the document covering a range of areas including effective communication, policy responses and physical works.
Ultimately the aim of identifying hotspots is to bring these areas to the attention of all parties who may be able to influence and reduce flood risk.
The draft SWMP was published for consultation in Spring 2013. We are currently amending the plan in the light of comments received and will publish the final version by the end of the year.
The Strategic Assessment and Background Information explains the terms used in these plans and provides overall background information across the County.
