Freasdail Wind Farm RES 6.2 ASSESSMENT METHODOLOGY AND SIGNIFICANCE CRITERIA 6 LANDSCAPE AND VISUAL 6.2.1 Methodology 6.1 INTRODUCTION 6. The LVIA has been based on guidelines provided in: 1. This chapter of the Environmental Statement (ES) evaluates the effects of the proposed Freasdail Wind Farm (hereafter referred to as "the Development") on the landscape and visual amenity of the Site (as A guide to the assessment of cumulative effect of wind farm developments (ETSU/DTI, 2000)1; shown in Figure 4.1 of this ES and hereafter referred to as ‘the Site’) and surrounding area.

The Landscape and Visual Impact Assessment (LVIA) takes account of the effect of the Development on Landscape Character Assessment (The Countryside Agency and Scottish Natural Heritage 2002) ; the landscape both within and beyond the Site since the landscape character and visual amenity Guidelines for Landscape and Visual Effect Assessment (Landscape Institute and Institute of effects are likely to occur at locations at a considerable distance beyond the Site boundary.
