Crossrail Act 2008

5 (1) Any work constructed under this Act for the purpose of providing a flood defence shall be maintained to the reasonable satisfaction of the Agency by the person who has control of the work.

(2) If any such work is not maintained to the reasonable satisfaction of the Agency, the Agency may by notice in writing require that person to repair and restore the work, or any part of it, or (if the person having control of the work so elects and the Agency in writing consents, such consent not to be unreasonably withheld), to remove the work and restore the site (including any sea defences) to its former condition, to such extent and within such limits as the Agency reasonably requires.

(3) If, within a reasonable period being not less than 28 days beginning with the date on which a notice in respect of any work is served under sub-paragraph (2) on the person who has control of that work, that person has failed to begin taking steps to comply with the reasonable requirements of the notice and has not thereafter made reasonably expeditious progress towards their implementation, the Agency may do what is necessary for such compliance and may recover any expenditure reasonably incurred by it in so doing from that person.

(4) In the event of any dispute as to the reasonableness of any requirement of a notice served under sub-paragraph (2), the Agency shall not except in a case of immediate foreseeable need exercise the powers of sub-paragraph (3) until the dispute has been finally determined.
