Collection: South West River Basin District preliminary flood risk assessments

The outstanding natural environment is recognised as one of the south west’s greatest assets. Just over 3 million people live in the South West River Basin District making it one of the least populated river basin districts, but the population is growing. By 2028 it will have grown by 16 per cent, the second highest increase of the English regions.

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.
