No official flood warning or alert is on record for areas near the centre of this district since 2006. No warning on record here means the Environment Agency has issued no flood warning or alert for a flood area within that distance since its record begins in 2006. Warnings are issued for areas, not addresses, and when flooding is expected rather than when it happens, and the record covers England only — so this is the state of the warning record, not evidence a place has not flooded.

No recorded flood extent is mapped near this district's centre. No recorded outline near the district means no flood was mapped here, which is not evidence none happened: the Environment Agency mapped only some floods, mapping effort rose sharply after about 2000, and surface-water flooding is largely absent from this record.
