Strategic flood management

3. Flood investigations

One of our responsibilities is to investigate significant flood events and to publish as a result what is called a Section 19 investigation report.


What is a Section 19 investigation?

A Section 19 investigation is a statutory requirement for Lead Local Flood Authorities (LLFA) required under the Flood and Water Management Act (FWMA) 2010. The LLFA for Buckinghamshire is Buckinghamshire Council. When a flood happens, a LLFA must, to the extent that it considers it necessary or appropriate, investigate:

  • which risk management authorities have relevant flood risk management functions, and
  • whether each of those risk management authorities has exercised, or is proposing to exercise, those functions in response to the flood.


What do we investigate?

We have established a list of criteria for Section 19 flood investigations, which includes:

  • flooding to a certain number of properties and businesses
  • significant road closures
