Wrigley opened its global innovation center, a 200,000-square-foot office and lab
complex, in the summer of 2005 on the northern tip of Chicago’s Goose Island. The
center houses the company’s research and development, packaging, engineering,
regulatory and quality-control departments.

TERRA provided civil design for the site, including grading, drainage and detention
design for the site, utility connections, dimensional control, permitting with City of
Chicago and construction services. The roof drainage was allowed to flow directly
into the Chicago River undetained. The remainder of the site drainage is sent to a
system which treats the stormwater runoff prior to being discharged into the river.
