Paragraph 37 I1

If by reason of the construction of any specified work or of the failure of any such work the efficiency of any ordinary watercourse for flood defence purposes is impaired, or that watercourse is otherwise damaged, so as to require remedial action, such impairment or damage must be made good by the undertaker to the reasonable satisfaction of Cambridgeshire County Council and if the undertaker fails to do so, Cambridgeshire County Council may make good the same and recover from the undertaker the expense reasonably incurred by it in doing so.
