The undertaker is required to carry out the authorised development in accordance with the latest flood risk assessment.

No part of the authorised development may commence until details of the surface water drainage strategy and (if any) foul water drainage system (including means of pollution control) for that part have been submitted to and approved by the relevant planning authority or, where the part falls within the administrative areas of both East Riding of Yorkshire Council and North Yorkshire Council, by both relevant planning authorities, and following consultation with the Environment Agency and the lead local flood authority where the surface water drainage strategy and/or foul water drainage system is affected by an updated version of the flood risk assessment.

The drainage strategy must be substantially in accordance with the framework surface water drainage strategy.

Any strategy approved pursuant to sub-paragraph (3) must be implemented as approved and maintained throughout the construction and operation of the authorised development.
