approximately 14,500 tonnes of CO2 every year, the equivalent of taking over 5,500 cars off the road. 1.2.7 This statement is set out in the following way:

· Chapter 1 provides an introduction to the development; · Chapter 2 describes the process of identifying the area of search and high level designing considerations; · Chapter 3 presents the design of the solar farm; · Chapter 4 considers outline baseline access undertaken so far; and · Chapter 5 outlines the key policy documents and Local Plan policies. OUTLINE DESCRIPTION OF THE SITE AND SURROUNDINGS 1.3.1 It is proposed to construct a solar farm and power storage units across a total area of approximately 110ha. However, the proposed deployment areas are dispersed over a wider area to ensure the scale of the facility sits sympathetically in the local landscape. The deployment sites are located to the west and south-east of the village Llanfihangel yn Nhowyn and to the south and south-east of the village Brygwran.

1.3.2 RAF Valley is situated to the south and the A55 lies to the north. SITE CONSTRAINTS 1.4.1 Drawing LC1001/01/01 identifies the environmental setting and constraints of land in and surrounding the proposal site.

1.4.2 Of note is the Site of Special Scientific Interest (SSSI) that is located partially on plot area 6 as is a Special Area of Conservation (SAC). A Scheduled Ancient Monument is located adjacent to plot area 3, furthermore there are several Listed Buildings surrounding the seven plot areas. 1.4.3 Drawing LC1001/01/01 also identifies three landscape character areas in which the plot areas are located.

Detailed assessments will also identify, where necessary mitigation to be incorporated into the design of the scheme to ensure environmental acceptability and enhancements. COMMUNITY ENGAGEMENT 2.3.1 An initial programme of community involvement has already commenced through contacting and advising Ward Members, Community Councils and near neighbours (to deployment areas) of the proposals. Further engagement with stakeholders is programmed when assessment works have been carried out and a draft planning application is available for review. A Statement of Community Involvement will detail the engagement process and the effect this had on the proposals. DESIGN ITERATION 2.4.1 Whilst several baseline assessments have been carried out further environmental assessments will be undertaken to inform the design of the proposed development. The proposed scope of assessment are detailed in the following section.

To help understand stage the proposal looks to be in broad accordance with these policy baseline conditions of the identified site preliminary reporting of the requirements. following key disciplines is included:

· Ecology; · Landscape character and Visual amenity; and · Cultural heritage.

6.1.3 The preliminary ecology survey found that the close proximity of some deployment areas to the RSPB Reserve and identified protected bird species means that special measures should be considered to protect high value species and habitats. 6.1.4 The deployment areas are located within landscape character areas that have medium sensitivity as they are influenced in many places by modern day developments such as wind farms, overhead lines and major transport corridors. Whilst there are a number of residential properties surrounding the deployment areas a viewpoint appraisal will be undertaken to illustrate the extent of visibility to the plot areas from representative locations within the study area.

6.1.5 Mitigation proposals will be developed for all the plot areas and is an integral part of the design and assessment process. The proposed mitigation and enhancement proposals will be developed to address identified landscape and visual issues, but also informed by ecological assessment and influenced by historical landscape structure 6.1.6 The initial heritage survey found that five of the seven solar plot areas
