The main purpose of the Strategic Flood Risk Assessment (SFRA) is to provide:
-
up-to-date information and guidance on flood risk
-
inform the selection of options for Local Plan allocations and
-
support the determination of planning applications.

SFRA 2010 mapping for Middle Level Commissioner Areas
For those villages which are entirely within Flood Zone 3 as defined in the 2017 SFRA only, the 2010 SFRA, which took account of flood defences, will be used as the basis for decision-making, and general market housing will only be permitted in areas shown as being in Flood Zone 1 as defined in that document.
Note [PDF, 26.5MB] tabled at the September 2017 Development Management Committee which sets out this information and the SFRA 2010 mapping for Middle Level Commissioner Areas.
