Paragraph 11

If any part of the specified works comprising a structure in, over or under a drainage work is constructed otherwise than in accordance with this Schedule, the Agency may by notice in writing to the Authority require the Authority, at the Authority’s expense, to comply with this Schedule or (if the Authority so elects and the Agency in writing consents, such consent not to be unreasonably withheld) to remove, alter or pull down the work and, where removal is required, to restore the site to its former condition to such an extent and within such limits as the Agency reasonably requires.
