The Flood Risk Regulations 2009 require each lead local flood authority (LLFA) to carry out a preliminary flood risk assessment (PFRA) for its area, and to review it every 6 years.
The reason for reviewing the PFRA is to make sure that it is up to date.
Using the PFRA, an LLFA must decide if any part of its area is at significant risk from local sources of flooding for example surface water, groundwater and ordinary watercourses. It must identify such areas as flood risk areas, and review them every 6 years.
Each LLFA is responsible for the content of its preliminary flood risk assessment and any updates to it.
