Flood Risk Alleviation and Watercourse Access
Where planning permission is granted for development that may increase flood risk, conditions may be imposed to require necessary alleviation works and ensure adequate access to watercourses. Discharge into waterways requires separate consent from Rivers Agency under Schedule 6 of the Drainage (NI) Order 1973.
Works required to alleviate flood risk may result in unacceptable damage to visual amenity, nature conservation interest or the man-made heritage. On the limited occasions where exceptions to this policy arise and planning permission is granted, conditions may be imposed:
• To require necessary alleviation works; and
• To ensure adequate access to watercourses.
In addition, Schedule 6 of the Drainage (NI) Order 1973, requires the consent of Rivers Agency for any discharge into a waterway.
