Paragraph 118 Agency accessI1

If by reason of the construction of any specified work or the failure of any such work, the Agency’s access to flood defences or equipment maintained for flood defence purposes is materially obstructed, the undertaker must notify the Agency immediately and provide suitable alternative means of access that will allow the Agency to maintain the flood defence or use the equipment no less effectively than was possible before the obstruction occurred and such alternative access must be made available as soon as reasonably practicable after the undertaker becomes aware of such obstruction, except in the case of an emergency in which case the undertaker must provide such alternative means of access on demand.
