Particular attention should be paid to the following points:
- Consent must be sought from the Department of Infrastructure Flood Management Division for any works that may affect any watercourse (excepting routine vegetation management), for example, riverbank engineering/ protection; installation of bridges, pipes and cross-channel fencing.
- Consent must be sought from the Department of Infrastructure before constructing anything or planting trees/ shrubs within 9.1 metres either side of a watercourse designated as a 'main river' under the Flood Risk Management Act 2013.
- For streams with a mostly stony substrate, works likely to disturb the channel or destabilise banks should be avoided from October to June (inclusive) in order to minimise impact on trout and salmon
- Disturbance of bankside vegetation, including reeds or bushes, should be avoided during the bird nesting season (March to August inclusive)
- If the invasive plants Japanese knotweed, giant hogweed or Himalayan balsam are found on or near river banks advice should be sought from:
