Respondent: Suffolk County Council

The reference to a ‘catchment’ approach to water management is recognised and supported. With a catchment strategy, neighbouring counties should be considered too. Watercourses and rivers reflect the properties of a catchment, rather than aligning with administrative county boundaries, posing cross boundary issues. Changes to the normal hydraulic regime, specifically fluvial and pluvial flooding as a result of growth should be accounted for on a cross-boundary scale. Both the River Waveney and Great Ouse run through Suffolk, thus cross boundary changes to water storage, flow and sedimentation could arise and should be taken into account.

Cross-boundary approach to storage and flood risk are particularly relevant strategic matters. Site specific mitigation may, however, be associated with green field run-off rates.
