corridor, such as fencing or ground protection This information would assist the contractor with the ACoW to micro site the trenches and manage the storage of materials and movement of vehicles to provide optimum embedded mitigation against tree and hedge loss or damage.
Pre-construction 40
The roots of retained trees along the edge of the working width would be protected from soil compaction by the enforcement of Root Protection Areas that would be fenced off from the construction (the extent of which would be calculated using guidance from BS5837: 2012)
41 42
The location of pre- and post-construction land drains would also be adjusted to avoid or minimise damage to tree roots.
If tree removal is required at Bealings and/or Waldringfield, a specific Arboricultural Method Statement for the crossing of the Onshore Cable Route in those areas would be agreed with the Local Authority.
During Construction 43
The typical mitigation measures that would be employed during construction to minimise the impacts upon trees and woodland are as follows:
Facilitation pruning may be recommended where tree crowns are at risk from impact by machinery or high sided vehicles
Reduced working width of 35m within woodlands (including woodland at target note 341, shown on Figure 24.2.2, Appendix 24.2 of the ES) by storing soils from the woodland areas within the working width of adjacent sections of lower value habitat (on the same landownership)
Soil excavated from within the woodland areas would be stored separately to that removed from either side of the woodland. This would protect any seeds which may be present within the ancient woodland soil. Soil would be stored in a fenced-off area; highlighting its different origin to soil excavated outside of the woodland and preventing mixing of the two
Where this would unacceptably restrict the working width or cannot be achieved due to adjacent hedgerows, the maximum area possible would be fenced and measures taken to mitigate the impacts of working beneath the canopy of the trees such as bog matting and sand padding to spread
