Flooding

It is the Vale of Glamorgan Council's responsibility to take reasonable steps to prevent water from running off the adopted highway onto private property

 

However, remember flooding is a natural occurrence and no drainage system or flood protection measures can give absolute protection from all flooding events.

 

The emergency response to flooding falls primarily to the emergency services working with the local authority. We coordinate evacuation, provide emergency accommodation and other social services.

 

 

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

  • Investigation findings

  • 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.

 

Flooding Incident Form

Due to the high number of flooding incidents and the impact of Covid affecting our ability to investigate we will be letter dropping all residents who live within the flooding areas to ask them to complete a Flooding Incident Form

We are now allocating extra resources to inspect and where necessary cleanse all highway drainage in areas affected by flooding. 40 full-sized builders skips have been made available to residents to help dispose of water-damaged furniture, floor coverings and other household items.

 

Please note: Any information we gather over the course of our investigations will be shared with Welsh Water and Natural Resources Wales.

Owner or Occupier of Property

The first responsibility for protection of property in the event of flooding lies with the owner or occupier of the property. The owner or occupier is also responsible for any subsequent losses, repairs or remedial measures necessary.

 

Owners or occupiers living near water courses or adjoining areas / fields which give rise to excessive water run-off should take appropriate precautions in advance of a forecast of bad weather as highway drainage systems are not designed for and cannot cope with, run-off from adjoining fields.
