C.3.2.2 Preliminary landscape character and significance analysis Building on information gathered in the scope and policy context, desktop research should include gathering descriptive material relevant to understanding the character and significance of the proposed development and surrounding area, sufficient to inform the preliminary assessment. Identify and describe (in a preliminary manner) the landscape character of the study area and surrounding landscape(s). Consider: • The individual landscape character units that occur across the region (refer to Landscape Character Units Practice Note, Section C.7.2). • The main natural, rural and built (urban) characteristics. • Particular locations, features or characteristics of the landscape that are important to understanding its character and significance (including current or historic land uses). • Prominent and culturally important locations from which the wind farm may be visible. • The visual character of the landscape(s). Identify and document in a preliminary manner the communities and stakeholders who may hold values relating to the wind farm site and surrounding landscape (e.g. for a landscape that has State or National significance). Following the desktop research, the proponent should: • Prepare a generic base map of the wind farm development and its surrounding context. Supporting information to provide context should include roads, settlements, prominent landform features and landmarks, and shire boundaries/ district boundaries (if applicable). • Identify and map the landscape character units that occur within the study area and wider region (refer to Landscape Character Units Practice Note, Section C.7.2). • Define and map (in a preliminary manner) the likely extent of the study area for the landscape assessment, which should include a wider contextual study area and a primary study area. The wider contextual study area should cover an area that: • Places the broad landscape character unit in which the subject land is located into the context of adjoining landscape character units; and • Encompasses the location of any existing or proposed wind farms or other major infrastructure works identified in C.3.2.5 Identification of possible cumulative impacts (page 80). The primary study area should equate to the anticipated Viewshed, or Zone of Visual Influence, of the wind farm (refer to Viewshed Mapping Practice Note, Section C.7.5). Following the analysis, it is recommended that a preliminary site inspection is conducted to verify assumptions made in the above desktop analysis. The reporting (which could include photos and sketch maps) should be sufficiently rigorous to: • Ascertain (in a preliminary manner) the extent to which the character of the landscape would be changed by a wind farm. • Draw preliminary conclusions about the significance of the landscape(s) in which the wind farm is to be sited. • Provide the study area for the briefs for all the tasks in the Full Landscape Assessment (page 80). • Provide the basis for briefs for the C.4.1.2 Landscape significance analysis (page 82). Page 78 Draft National Wind Farm Development Guidelines – 2 July 2010
The preliminary landscape character and significance analysis should ascertain (in a preliminary manner) the extent to which the character of the landscape would be changed by a wind farm based on: • The size of the landscape character unit (refer to Landscape Character Units Practice Note, C.7.2). • The sensitivity to change of the landscape, including its capacity to absorb a wind farm both visually and in relation to non-visual elements such as documented social, cultural and environmental values. C.3.2.3 Preliminary views analysis This task should start by identifying all existing regionally and/or locally significant views and viewing locations. Other key locations from which the proposed wind farm is likely to be visible should then be identified (in a preliminary manner). These locations should include both public use locations (such as roads/ tourist drives, settlements, lookouts, recreation areas), within the subject land and surrounding area. With respect to views from private residences in relation to wind farm planning it should be noted that there is a typical understanding that there is no legal right to a view. Views from individual residences should not be included within the assessment and made publicly available. It is suggested that this work, if required, should be carried out as part of the community consultation process, and in particular, consultation with the closest neighbours to the wind farm development. Sought information (such as the location of buildings/ settlements and towns/ lookouts) can be initially compiled from aerial photography and then followed up and verified through fieldwork. It may also be worthwhile seeking information from local relevant authorities about the possibility of future developments/ dwellings within the subject land and surrounding area. Particular attention should be given to locations from which the proposed wind farm is likely to be visually prominent. These locations should be recorded on site using a handheld GPS. All preliminary views should then be subsequently verified and documented through on site photography. At this stage, it is highly recommended that a preliminary 3D ‘wireframe’ computer model that accurately depicts the wind farm development in the landscape is prepared (see 3D Computer Modelling Practice Note, Section C.7.4). Preliminary ‘wireframe’ depictions can be useful at this early stage to provide an accurate assessment of the wind farm development. This ‘dynamic’ assessment system allows the proponent to make preliminary adjustments to the location or scale (e.g. number of turbines) to provide the best fit in this landscape. If warranted (and given a preliminary ‘wireframe’ model has been prepared), the task could map the likely ‘viewshed’ of the wind farm (see Viewshed Mapping Practice Note, Section C.7.5). Furthermore, the task could prepare preliminary ‘wire frame’ photomontages that accurately demonstrate the visibility of the wind farm development in the landscape from key locations from which the development will be viewed (Photomontage Practice Note, Section C.7.6). This would normally be undertaken in the Full Landscape Assessment (page 80), but could justifiably be undertaken during this preliminary assessment phase if landscape impacts are anticipated to be potentially decisive when the application for the proposal is assessed. While models and photomontages should be accurate, they do not need to be of high quality presentation level at this stage. Draft National Wind Farm Development Guidelines – 2 July 2010 Page 79
