As a Lead Local Flood Authority (LLFA) Southampton City Council has a duty under the Flood and Water Management Act (2010) to investigate flood events that occur within the city boundary.
Section 19 of the Flood and Water Management Act (2010) states that, on becoming aware of a flood in its area, a lead local flood authority must, to the extent that it considers it necessary or appropriate, investigate –
a) which risk management authorities have relevant flood risk management functions, and
b) whether each of those risk management authorities has exercised, or is proposing to exercise, those functions in response to the flood.
It is not the responsibility of the Investigating Officer to resolve the flooding, however they will investigate the cause and notify the relevant authority who then have the duty to resolve the flooding. In Southampton these authorities could include:
• Southampton City Council
• Southern Water
• Environment Agency
• Associated British Ports (ABP)
Private landowners also have responsibilities in relation to land drainage and riparian ownership.
Upon learning of a flood event within Southampton, the Investigating Officer will follow the established Flood Investigations Protocol whereby it will be determined whether an investigation should be carried out using the Flood Investigations Guidance, taking into account the available resources and significance of the event. Both the protocol and guidance documents are available to view from the downloadable documents section of this page.
Where an investigation has been carried out, a flood investigation report will be produced and published. Reports will be available on this webpage shortly after the investigation is completed.
