Strategic Flood Risk Assessment (SFRA)

The Council has recently undertaken a comprehensive Strategic Flood Risk Assessment (SFRA) exercise.

This included:


·        a Level1 Assessment and Climate Change Addendum in 2016,
·        a sequential test of the sites put forward for development in the 2016 Call for Sites exercise and considered potentially suitable for development through the            Strategic Land Availability Assessment, and
·        a Level 2 Flood Risk Assessment of the 13 sites preferred for development.  

Please note, for the Level 2 Assessment the flood risk information for each of the 13 sites has been mapped and the detail of the risk included in the accompanying table.  

To activate the information within the map, please tick the box adjoining the information you require. Please note, some sites have only very small areas within a Flood Zone 2 or 3 which occasionally forms the boundary to the site, and is not clearly seen on the Flood Map.
