East Anglia ONE Offshore Windfarm Landscape Management PlanWork No 38 to 41


August, 2016


4.5.3 Internal service road 45.


A concrete internal access and service road and car parking area will be constructed within the substation. This is a 5m wide circulation road designed to meet the load bearing capacity of the vehicles delivering the electrical components.


4.5.4 Gravel surfaces 46.


There will be no vegetation within the substation as this would risk cross-over shorting and fouling of the equipment. Likewise, it is best practice to reduce the maintenance required within the substation for Health and Safety reasons. In order to provide a neutral, conductive free ground surface, an inert gravel ground dressing will be used within the substation, consisting of a locally sourced flint gravel where possible.


4.5.5 Self-binding gravel path 47.


A 1m wide footpath will be located around the outside of the perimeter fence and will be used for maintenance purposes. This footpath will be a timber edged self-binding gravel path, using a grey, angular gravel, free from clay with sufficient grit to enable compaction.


48.


4.6 Minor structures and services Minor structures within the proposal include:


 2.4m high perimeter fence, comprising a mesh fence configuration (Hi SEC Super 6 or similar solution) and corresponding double access gates.


 Deer proof fencing with rabbit mesh to delineate boundaries and protect new woodland planting.  Lighting within substation is to be low-level with occasional task lighting.


49. The following drawings within this landscape management plan illustrate these proposals:


 Appendix 1 - Hard Landscape General Arrangement (OPEN_150796_EA_H001).  Appendix 5 – Typical Construction Details: Fencing (EA1-GRD-DG-OPEN-796_D002).  Appendix 10 - NBS Landscape Specification (Section Q40 on fencing).


4.7 Tree protection 50.


Trees that are to be retained and are within the construction area will be protected by Heras fencing braced with scaffold poles (as per BS 5837:2012) as shown in the Tree Protection Plan (Appendix 11). Protective fencing to BS 5837:2012 is braced to protect from failure from impacts. The fencing is installed at a specified distance from the tree defined by the Root Protection Area (RPA) as calculated by an Arboricultural Clerk ofWorks.


51.


Trees and hedges outside the construction area, but within the DCO Boundary, will not be protected as it is assumed they will be at a distance far enough not to incur unnecessary or accidental construction damage.


52.


The storage of materials, spoil, vehicles, welfare facilities etc. will not be permitted within the protective fencing (i.e. within the RPA).


53.


An Arboricultural Clerk ofWorks will be appointed during construction to oversee the erection of protective fencing, the protection of trees to be retained and to ensure that all tree works are undertaken to the required standards. All tree works during construction, for example felling, to be undertaken by qualified arboriculturalist to BS 3988:2012: TreeWork – Recommendations.


54.


Appendix 11 – Tree Protection Plan (OPEN_150796_EA_T001) illustrates the tree and hedgerow removal required, together with tree protection areas.
