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


August, 2016


(3) The landscaping management scheme must be implemented as approved. Implementation and maintenance of landscaping


1.3 Background 6.


The landscape proposals for the substation are designed to meet a key requirement: to provide visual screening of the substation in views from the surrounding area. This requirement formed a large part of the mitigation proposals which were recommended as part of the Environmental Statement for this development. In this respect a significant element of the landscape proposals are the new woodland and hedgerow planting, supplemented with earthwork bunds.


7.


The local landscape character, predominately agricultural and rural is influenced by the presence of the existing National Grid substation complex. The landscape proposals for the EA ONE substation therefore need to respond to both the rural character of the site and also the National Grid substation.


8.


Likewise, in formulating the landscape proposals, it was required to have due cognisance and consideration of other future energy project proposals that may occur within the local area; although the detail and definition of which are beyond the scope of this document.


9.


The key elements and approaches in the landscape proposals, as illustrated in the Soft Landscape General Arrangement (Appendix 2), therefore include:


 Hedgerows and woodland blocks provide required mitigation and visual screening.  Hedgerows and woodland relate to local landscape context.  The size and shape of woodland blocks respond to technical constraints (e.g. overhead and underground cable routes).


 Earthworks bunding around the western and southern perimeter will have natural looking, gentle slopes where possible (1:5 to 1:20) when looking towards substation.


 Western bund planted with trees to provide additional visual screening  Hedgerow planted along top of bund to screen and soften the substation perimeter fence – especially in views from the public bridleway to the south where technical constraints restrict planting opportunities for trees.


 Access road framed by hedges and woodland blocks to create visual separation from the existing wide bridleway and the National Grid substation access road.


 Species rich grassland areas will be established to provide a low maintenance ground cover which also enhances the local biodiversity in areas that are not to be returned to agricultural use or planted as woodland.


 Existing agricultural land use will be retained in other areas with arable fields, such as to the east between Bullenhall Farm and the Bramford NG substation.


 Amenity grasses used immediately next to perimeter foot track and along access track verge.  Sustainable Drainage System (SuDS) attenuation basin to include a permanent water pond which will have ecological benefits through habitat creation on the site.


 Additional ecological mitigation where deemed appropriate and necessary.
