PROJECT+SITE HISTORY OVERBUILD+LOBBY LOBBY WALL

Evolution of Plaza / Park Design

October 2011 • 3-story parking structure • Public park 35’ above plaza • 200 parking spaces • ½ acre of hardscape

January 2013 • 2-1/2 story parking structure • Parking reduced by 50 spaces • Plaza retail reduced 20% • Public ‘piazza’ • Landscape increased by 20%

•

The prior designs are but a representative sample of more than 10 iterations on design

•

20+ meetings with Alderman and DHED over 18+ months

•

Current plan reflects continual refinement and improvement to quality of public

July 2013 • 1-story parking structure, hidden underneath park • Parking reduced to 75 spaces • Landscaping constitutes more than 75% of total site area • Continuous landscaping along Randolph St
