Flood Investigation Reports

Under Section 19 of the Flood and Water Management Act 2010, Rhondda Cynon Taf County Borough Council, as the Lead Local Flood Authority (LLFA), have a duty to investigate and publish reports on flood events that occur within its area to the extent that it considers it necessary or appropriate.

Section 19 of the Flood and Water Management Act 2010 provides that:

(a) which risk management authorities have relevant flood risk management functions, and

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

 The flood investigation reports include:

  • Background information on location of flooding
