Allan Wyatt – Panel Presentation Slide 2

• 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

Impact assessment

Allan Wyatt – Panel Presentation Slide 10

Methodology – Criteria for public domain viewpoints

Allan Wyatt – Panel Presentation Slide 11

Methodology – Scale of effects

• Nil

• Positive

• Negligible

• Low

• Medium

• High

Rating is not an averaging process

Allan Wyatt – Panel Presentation Slide 12

Methodology – Photomontages

• Images in report for reference

• A3 images all 80O FOV

• Panoramas would understate impact

• Assumed correlation between 18 lanes and visual impact not supported

• 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

Allan Wyatt – Panel Presentation Slide 39

Construction impacts:

• TBM launch sites

• Site compounds on public open space

• Temporary alienation of public parkland

Conclusion - construction

Allan Wyatt – Panel Presentation Slide 40

Operational impacts:

• Noise walls

• Ventilation structures

• Lack of space for landscaping

• Permanent loss of public parkland

Conclusion - operation
