Where can I find an IDB?
IDBs manage drainage districts which occur in areas of special drainage need. The district each IDB covers is therefore determined by the local hydrology and not by political boundaries such as those of counties.
They either occur in broad open areas of lowland such as The Fens, Somerset Levels or Humberhead Levels or within the floodplains of rivers.
IDBs are geographically concentrated in Cambridgeshire, Kent, Lincolnshire, Norfolk, Nottinghamshire, Somerset and Yorkshire.
