Flood investigations

Under Government legislation, we are the Lead Local Flood Authority (LLFA) and are required to formally investigate flooding incidents where appropriate.

If an incident has a significant local impact an investigation will be triggered. It would not be practical or possible to investigate every reported incident. You can report a flooding incident through our form..

Reports are investigated if it has one or more of the following impacts:

  • caused internal flooding to a property used for residential or commercial purposes
  • resulted in major disruption to the flow of traffic
  • posed, or could have posed, a risk to human health
  • adversely affected the functioning of critical infrastructure
  • caused harmful impacts to environmentally or socially important assets

The purpose of an investigation is to:

  • investigate the what, when, why, and how the incident took place
  • act as a means of identifying potential future recommendations for actions to minimise the risk or impact of future flooding

These investigations (Section 19 reports) outline recommendations and actions that various organisations and authorities can do to minimise flood risk in affected areas. It is important to note that a Section 19 report is not an in-depth analysis of flooding risks or mechanisms.
