District flood risk

Strategic Flood Risk Assessment Report July 2013

We commissioned consultants to undertake a Strategic Flood Risk Assessment (SFRA) for the district and the initial report was published in 2013. The Environment Agency supported the assessment by monitoring the methods used and checking the model results.  The assessment is part of government policy for planning authorities contained in the National Planning Practice Guidance.  The work was carried out jointly with the Vale of White Horse District Council and the report covered both districts. It can be found in the Strategic Flood Risk Assessment archive This link will take you to an external website...

We consider flood risk when preparing planning policies and direct development away from areas at highest risk of flooding as well as avoid inappropriate development in areas at some risk of flooding.

The assessment identifies areas that may be at flood risk. Taking account of climate change, it details factors that may influence the risk and identifies what development may be suitable for different areas of land. 

The maps that result from the assessment show flood zones 2 and 3.

Flood zone 2 is the medium probability flood risk area that has between a I in  100 and 1 in 1000 year annual probability of flooding (1% - 0.1%) in any year.  Flood zone 3 is the high probability flood risk area that has a 1 in 100 or greater annual probability of flooding (>1%) in any year.

Where existing properties fall within one of the flood zones owners may wish to consult the Environment Agency-s Flood Map website, which gives advice on how to prepare for flooding.

Only rivers and streams that flow through our towns and larger villages, where significant amounts of change may happen, were assessed in detail to help guide decisions about future development.  The report identifies the sources of data and gives advice to us as local planning authority about how to consider proposals in different areas.  In addition it provides advice for developers and landowners about  how potential development on different areas of land should have regard to flood risk.
