Submitting information

If you have information that could help us with these investigations, such as your property flooded or photos of the flooding, please submit this to us if you have not already done so. Report a flood – Oxfordshire Flood Toolkit.

Our thresholds for doing a formal investigation and report are also set out on the above webpage.

Investigations will be undertaken in partnership with the district and city councils, the Environment Agency, other Risk Management Authorities, and the communities and businesses impacted. 

Legislation

The requirement to investigate and report is set out in the Flood and Water Management Act, 2010 that states:

1) On becoming aware of a flood in its area, a Lead Local Flood Authority must,

to the extent that it considers it necessary or appropriate, investigate: ‐

a. which risk management authorities have relevant flood risk management

functions, and

b. whether each of those risk management authorities has exercised, or is

c. proposing to exercise, those functions in response to the flood.

2) Where an authority carries out an investigation under subsection (1) it must: ‐

a. publish the results of its investigation, and

b. notify any relevant risk management authorities

Other locations

In locations where flooding of properties, businesses or infrastructure occurred but did not meet our thresholds for formal investigation and reporting we or partners will where possible investigate the source of the flooding and make any recommendations that could reduce future risk. But we cannot do so everywhere, and we will prioritise formal investigations and reporting.

Scope of investigations and reporting

It is important to note that while the Flood and Water Management Act, 2010 gives Oxfordshire County Council as Lead Local Flood Authority the duty to investigate and report on flooding that meet our thresholds, and we can make recommendations it does not give us with the powers or funding to act on all these recommendations, or make others undertake all recommendations.

We will work with others to promote and encourage the implementation of these recommendations, but it is for the relevant responsible body or persons to assess each recommendation in terms of the legal obligation, resource implications, priority and cost/benefit.
