Flood investigations
Under Section 19 of the Flood & Water Management Act, when flooding reaches a defined trigger level a formal investigation is undertaken and will be published on this page.
This is "significant flooding" which is defined as:
- flooding that affects 20 or more properties internally in one flood event within the same location
- flooding that affects significant lengths of public highways and lasts for a period of 3 hours or more from the onset of flooding
These areas can also be viewed on our Flood and Water Management App.

We are currently looking at what support can be provided to individual properties. We will continue to work closely with the other primary agencies, such as the Environment Agency and the water companies, to:
- understand the cause of flooding events
- identify improvements in infrastructure and policy
We will work with local planning authorities to identify opportunities for local drainage improvements from new developments.
