14.—(1) Development must not be commenced within the 1% plus 30% for climate change flood extent of the Main Dyke, illustrated in Figure D8 of the Flood Risk Assessment (document reference TR010035/APP/5.2–v1) until details of a temporary compensatory flood storage scheme is submitted to and approved in writing by the Secretary of State. The scheme must include details of the design, function, construction and, as appropriate, decommissioning of the temporary compensatory flood storage area, to ensure that a suitably engineered solution is provided that will not impede access to Main Dyke (Skippool Creek) for maintenance purposes and will allow for the storage and subsequent drain down of flood waters that would be displaced by the development.
(2) The scheme must be fully implemented as approved and subsequently maintained in accordance with the approved details until it is decommissioned.
