Dominick's will close stores on Dec., 28, 2013.
Earlier this week, Dominick's parent company - Safeway - announced plans for three of its 13 stores in Chicago, which will be sold to Mariano's.
The task force will focus on the economic impact of certain vacant spots of land. People will still have access to fresh food and vegetables in key areas.
The task force will also give support to workers who will soon be unemployed and will have representation from the City Council, labor, city departments and agencies as well as industry experts.
Mariano's is buying three stores in Chicago on South Ashland, West Chicago Avenue and North Sheridan Road. The other eight are suburban stores in Park Ridge, Western Springs, Northfield and Westchester, and stores in Buffalo Grove, Gurnee, Aurora and Shorewood.
