Collection: Dee River Basin District preliminary flood risk assessments

The Dee River Basin District lies partly in England and partly in Wales.

The Welsh part of the Dee River basin District includes parts of North East Wales. You can find information about flood risk planning in Wales on the Natural Resources Wales website.

The English part of the Dee River Basin District includes parts of Cheshire, Shropshire and the Wirral. Information on these areas is included in the preliminary flood risk assessments for Cheshire West and Chester Borough Council and Shropshire Council.

Under the Flood Risk Regulations 2009, each lead local flood authority must carry out a preliminary flood risk assessment (PFRA) for its area and review it every 6 years.

PFRAs are used to identify areas where the risk of flooding is significant.
