How will we generate the Alternative Solutions?
22
Case Studies • Help us understand the issues, technical
challenges, ideas and economics of the projects
Public Ideas • Ideas proposed by the members of the public and
past design proposals
How will we generate the Alternative Solutions?
23
Design Ideas • Six international design teams selected through a
competitive process to participate in an 8-week ideas generating exercise
• Two teams were assigned to each of three EA options: Improve, Replace, and Remove
• Detailed briefing on existing conditions and concurrent studies
• Feedback provided by stakeholder and technical committees mid-way through
• The complete design submissions are available for further review on our website
24
Questions for you to think about
• Which ideas are most consistent with your vision for the waterfront and the city?
• What ideas do you think are the most important to consider as part of the study?
• What ideas do you think are least important to consider as part of the study?
• Do you have any other ideas to suggest?
