Response to Flooding on 23 December 2020
On 23 December 2020, the Vale of Glamorgan experienced on average 33mm of rainfall over an 11hour period. During this intense rainfall a number of properties across the authority experienced internal flooding, in particular houses in Dinas Powys, Sully and Penarth.
As a lead Local Flood Authority, we have a statutory duty to log all instances of flooding and investigate where necessary.
Under Section 19 of the Flood and Water Management Act 2010, Vale of Glamorgan 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. A section 19 flood investigation report is a public statement of the circumstances of a flood event and what parties have a role in managing the risks. The Council has appointed a specialist consultant to assist in investigating the flooding as part of the section 19 report.
The flood investigation reports will consider:
Background information on location of flooding
Summary of rainfall event, information on the extent of flooding
The roles and responsibilities of each RMA
Recommended actions following the investigation.
As part of our response to the flooding incident on the 23 December, we have been working in partnership with Natural Resources Wales and Welsh Water to investigate areas, in particular Dinas Powys where a large number of properties were affected by main river flooding.
