NEXT STEPS


Proposed Next Steps

• Further design investigations and treatment of 2 options for Segments 1-2 - within existing EWL footprint - hugging the edge option

• Framework Plan Segments 1-5 Captures issues, opportunities and desired outcomes, spatial relationships at a high diagrammatic level with supporting written commentary
