• Urban Design Approach
• Landscape, visual and recreational values
Evaluation objective:To minimise adverse effects on landscape values, visual amenity, recreational and open space values and to maximise the enhancement of these values where opportunities exist.
Scoping requirements

Methodology – Scale of effects
• Nil
• Positive
• Negligible
• Low
• Medium
• High
Rating is not an averaging process

Methodology – Photomontages
• Images in report for reference
• A3 images all 80O FOV
• Panoramas would understate impact

• Landscape impact of loss of parklandacknowledged
Response to submissions
Allan Wyatt – Panel Presentation Slide 38
• Assertion that not all viewpoints have been accessed – agree
• Assertion that these make adifference to the overall assessment –disagree
• Confusion between visibility and impact, especially in relation to ventilation structure
Response to landscape & visual amenity evidence – Stephen Schutt
