Sustainable Drainage Systems (SuDS)

Requirements for integrating sustainable drainage into new development, in line with DEFRA's National Standards.

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.
