43.—(1) Following construction of the new flood defence embankment at Cherry Cobb Sands, the Cherry Cobb Sands breach must not be made in the existing flood defences without the prior written consent of the Environment Agency, in consultation with Natural England and the MMO.
(2) The Cherry Cobb Sands breach must not be made until the new embankment has had an adequate period of time (likely to be, but not limited to, one winter period (November to April inclusive)) in which to stabilise and for vegetation to become established on the embankment to ensure the integrity of the new flood defences.
(3) No development is to commence until a scheme to compensate for the impacts of piling noise on migratory salmon from the construction of the authorised development has been agreed with the Environment Agency. This must include, but is not limited to, a monitoring scheme to ensure the intended benefits of the scheme are realised and necessary actions are taken.
(4) No development is to commence until an assessment of the impacts on Stone Creek, Cherry Cobb Sands Creek and Keyingham Drain has been submitted to and agreed by the relevant planning authority, in consultation with the Environment Agency, together with an outline scheme of remedial action if the impacts on those locations should be greater than those assessed.
(5) Any remedial action must be carried out if the corresponding greater impacts occur.
44.—(1) No development is to commence until the detailed design of the Regulated Tidal Exchange (“RTE”) sluices has been submitted to and approved by the relevant planning authority, in consultation with the Environment Agency.
(2) The detailed design information must include the size and flow capacity of the sluices within the RTE scheme.
(3) No development is to commence until the detailed design of the channel leaving the Managed Realignment site and the invert level has been submitted to and approved by the relevant planning authority, in consultation with the Environment Agency, to include detailed design drawings, including dimensions.
(4) The discharge channel exiting the realignment site must be no larger than that currently presented and assessed in EX 28.3 Part 3 (11.6 metres bed width (invert level 1.5 metres AOD) with 1V:3H side slopes rising to an edge weir level of 2.0 metres AOD), unless otherwise agreed with the Environment Agency.
(5) The invert level of the drainage channel must be no higher than that currently presented and assessed in EX28.3 Part 3, Final Compensation Proposals, October 2012, (1.5 metres AOD), unless agreed otherwise in writing with the Environment Agency.
