City officials plan to conduct a voluntary evacuation drill for part of downtown to better prepare for emergencies, Mayor Richard Daley announced Monday.
Daley said the Sept. 7 drill was planned in conjunction with National Preparedness Month, but he released few other details.
An e-mail obtained by The Associated Press addressed to tenants in an affected building indicated the drill involves four properties at the intersection two main downtown thoroughfares — Monroe Street and Wacker Drive — including the building that houses the Chicago Mercantile Exchange.
