This page focuses on KCC as Lead Local Flood Authority, who will be consulted on major development proposals in relation to local flood risk. However, as Highway Authority, KCC may adopt drainage systems associated with highway drainage. Additional information about what is required when designing SuDS in relation to highways is provided here.
SuDs Overview
KCC emphasises that new development must integrate SuDS that manage rainfall naturally, deliver multiple benefits, and include clear long-term maintenance arrangements. In line with DEFRA’s National Standards, it is expected for SuDS to mimic natural drainage and manage surface runoff at or close to the surface and as close to its source as practicable – simple pipe to strategic large basins will not be […]
