Strategic Flood Risk Assessment

Strategic Flood Risk Assessment (SFRA) provides a comprehensive and robust appraisal of the extent and nature of flood risk from all sources of flooding, now, and in the future, taking into account the effects of Climate Change and its implications for land use planning.

National Policy requires that local planning policies use the results of the SFRA to direct development away from areas at greatest risk of flooding when preparing the Local Development Plan. The Study sets out the flood risk constraints to help inform the Local Plan, Neighbourhood Planning, and the determination of planning applications in North Norfolk.

The SFRA has been produced in collaboration with the Environment Agency (EA). It informs the EA flood risk mapping and provides the most up to date flood extents for all sources of flooding. The SFRA also projects flood risk forward into the future, taking account of predicted sea level rise and increased annual rainfall as a result of climate change. The SFRA is primarily a tool to inform the planning of future development such as new housing, schools and businesses. To make sure that these developments remain safe throughout their entire life, the Council must plan for how flood risk will be in the future, not just how it is now.

The SFRA also provides a comprehensive source of information and guidance on flood risk for North Norfolk, identifying the requirements for site specific flood risk assessments and allows the authority to determine the risks from all sources of flooding taking into account Climate Change.

The SFRA should be read in conjunction with the Introductory Note and the relevant technical appendices and explanatory text contained in Appendix D, along with the Addendum report April 2018.
