Springfield City Council members are asking the city's corporation counsel for additional details involving potential locations of local marijuana facilities before possibly taking up a proposal next week to change the city's zoning code.

Springfield Ald. Frank Edwards (1st) said a vote on the proposed zoning ordinance could be postponed if aldermen still have questions about where medical marijuana facilities can legally operate come Tuesday's council meeting, the State Journal-Register reported.

The proposed ordinance currently under consideration by the council mirrors state rules on where medical marijuana cultivation centers and dispensaries can open as part of Illinois' Compassionate Use of Medical Cannabis Pilot Program Act.

Under the pending Springfield measure, cultivation centers in the city would have at least 2,500 feet away from schools, day cares and other places zoned for residential purposes. Dispensaries would also need to be at least 1,000 feet away from schools, day cares, residential dwellings and doctor offices.

Corporation Counsel Todd Greenburg said dispensaries could be defined as a drugstore, permitting the facilities to possibly open in downtown Springfield.
