Flood investigations

As the Lead Local Flood Authority (LLFA), we have a duty to investigate flooding when it is 'necessary and appropriate' (Section 19 of the Flood and Water Management Act 2010).

Any incidents of flooding should be reported so we can:

• Keep accurate records
• Determine which areas are most at risk
• Prioritise areas for interventions

When flooding is reported we will decide whether to undertake a flood risk investigation. This is likely where:

• A property has been flooded inside on more than one occasion
• Five or more properties have been flooded inside during a single flood incident
• Critical infrastructure has been affected by flooding
• The source of flooding is ambiguous

The investigation will identify and document:

• Which Risk Management Authorities (RMA) have a flood risk management function in relation to the flood
• What each RMA is going to do, or has done in response to the flooding incident
