Paragraph 76 I1

If by reason of the construction of the authorised development or of the failure of any such works the efficiency of any Flood Protection Work is impaired, or any such Flood Protection Work 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 the Agency and if the undertaker fails to do so, the Agency may make good the same and recover the expenditure reasonably incurred by it in doing so from the undertaker.
