Paragraph 26 Surface water drainageI1

No authorised development may commence until, following consultation with NRW, details of the surface water drainage system (including means of pollution control) have been submitted to and approved by the relevant planning authority.

The details of the surface water drainage system submitted under paragraph (1) must accord with the Outline Surface Water Management Plan at Annex 8.1 of the environmental statement to ensure that existing runoff regimes are maintained where possible and no increase in peak runoff is experienced within receiving watercourses as a consequence of the authorised development and shall include a mechanism to establish a baseline for the existing surface water drainage conditions.

The surface water drainage system is to be constructed in accordance with the approved details.
