Strategic Flood Risk Assessment - March 2026
This Level 1 Strategic Flood Risk Assessment (SFRA) is an update to the previous SFRA, published in 2016, using the latest flood risk information and data available at the time of writing, together with the most current flood risk planning policy and guidance.
The updated SFRA forms an essential part of the evidence base required to support the new Local Plan.
The key objectives of the SFRA are to:
- set out where flooding could happen now and in the future;
- help decide where new development should go;
- provide maps showing flood risk from all sources across the borough;
- provide a reference document which all parties involved in development planning can use for advice and guidance on flooding from all sources.
The main report and appendices are below.
