The Committee on Economic, Capital and Technology Development met briefly yesterday afternoon to approve a property tax exemption for EDE Corp., the only exhibition display company based in Chicago. The 35-year-old, family-run company sought a Class 6(b) property tax incentive to expand their operations to a neighboring, vacant 35,000-square-foot-industrial building at 3790 W. 74th St. in the 13th Ward. If approved by the full City Council tomorrow, the company would save approximately $254,000 in tax savings over the 12-year period, and could re-apply for the tax break when it expires.
