Draft PPS18: Renewable Energy
Annex 1 Wind Energy Landscape and Visual Impact: Ancillary Development
A61. Ancillary elements also need to be fully addressed, as their impact can often be significant. Access tracks should be routed and designed to minimise both visual and habitat impacts. This can be minimised by careful route selection, which takes account of layout and appropriate surfacing material together with the impact of cuttings, embankments and drainage channels. Managing problems of erosion and providing for reinstatement of vegetation along the track is essential. Fencing, buildings and anemometer masts should be located and designed in a way which minimises clutter. It should be noted that peat is very slow at reinstatement and may require active management, e.g. brashings from nearby habitat, to limit the visual impact and erosion potential. The location and extent of the use of any borrow pit should also be indicated in the visual assessment.
A62. The impact of the transportation of components to site on the minor road network and on the associated trees and hedges should be assessed e.g. transportation involves 40m length lorries requiring large turning circles.
A63. Power lines connecting the individual turbines to the on-site substation will be underground. To avoid visual confusion, routing and design of power lines, connecting the wind farm substation to the electricity distribution system, will require sensitive treatment.
