C.4.2 Visual Impact Assessment<br />

The output from the tasks below is a Visual Impact Assessment Report that:<br />

• Describes the wind farm proposal and surrounding landscape(s).<br />

• Describes the identified landscape and visual impacts, and the values on which they<br />

impact.<br />

• Evaluates the acceptability of individual landscape and visual impacts and of the<br />

wind farm as a whole.<br />

• Describes the method used to identify and rate impacts.<br />

• Includes supporting material including graphic depiction of impacts.<br />

The Visual Impact Assessment Report should clearly identify:<br />

• Any high-level negative impacts (e.g. those on landscapes of state or national<br />

significance, or which totally and irreversibly alter a value).<br />

• Any impacts on significant values for which there are unlikely to be any practical<br />

mitigation measures available.<br />

• Any impacts on significant values for which there are likely to be practical mitigation<br />

measures available.<br />

• Any positive landscape and/or visual impacts or benefits (e.g. enhanced scenic or<br />

visual values) of the wind farm, including those described by community-stakeholders.<br />

For a contentious project, the peer reviewer could test the results of the following tasks by<br />

using either the same method as the consultant or the peer reviewer’s recommended<br />

methodology. The decision to undertake a peer review is at the discretion of the relevant<br />

authority and proponent, if so required.<br />

C.4.2.1<br />

Assessment of impacts on landscape character and significance<br />

The impacts (positive and/or negative) of the proposed wind farm (including all<br />

components) on the character and significance of the landscape should then be<br />

identified and described.<br />

Particular consideration should be given to:<br />

• Specific features of the wind farm development which impact on the identified values<br />

of the landscape.<br />

• The degree to which character or significance is lost or altered by the wind farm<br />

development.<br />

• The scale, nature, duration and reversibility of impacts.<br />

The impact of the proposed wind farm (including all components) on the character and<br />

significance of the landscape should then be evaluated. The following questions should be<br />

addressed in the evaluation:<br />

• How does the wind farm impact on identified on valued landscape character and<br />

features<br />

• Is the impact on values of local, state, national or international importance<br />

• Do the effected stakeholders and communities understand the potential impacts on<br />

the landscape and its surrounds<br />

• Is the landscape character and features completely/partially lost or altered<br />

• To what extent are the negative impacts balanced by positive landscape benefits<br />

• What is the likelihood for removal of the wind farm and reinstatement of the<br />

landscape following decommissioning<br />
