"Petition" means the petition described in this Section.
"Precinct" means the smallest constituent territory within a municipality with a population of over 500,000 in which electors vote as a unit at the same polling place in any election governed by the Election Code.
"Restricted cannabis zone" means a precinct within which home cultivation, one or more types of cannabis business establishments, or both has been prohibited pursuant to an ordinance initiated by a petition under this Section.
Upon receiving a petition containing the signatures of at least 25% of the registered voters of the precinct, and concluding that the petition is legally sufficient following the posting and review process in subsection (c) of this Section, the city clerk shall notify the local alderperson of the ward in which the precinct is located. Upon being notified, that alderperson, following an assessment of relevant factors within the precinct, including, but not limited to, its geography, density and character, the prevalence of residentially zoned property, current licensed cannabis business establishments in the precinct, the current amount of home cultivation in the precinct, and the prevailing viewpoint with regard to the issue raised in the petition, may introduce an ordinance to the municipality's governing body creating a restricted cannabis zone in that precinct.
To be legally sufficient, a petition must contain the requisite number of valid signatures and all such signatures must be obtained within 90 days of the date that the city clerk publicly posts the notice of intent. Upon receipt, the city clerk shall post the petition on the municipality's website for a 30-day comment period. The city clerk is authorized to take all necessary and appropriate steps to verify the legal sufficiency of a submitted petition. Following the petition review and comment period, the city clerk shall publicly post online the status of the petition as accepted or rejected, and if rejected, the reasons therefor. If the city clerk rejects a petition as legally insufficient, a minimum of 12 months must elapse from the time the city clerk posts the rejection notice before a new notice of intent for that same precinct may be submitted.
If a notice of intent to initiate the petition process to prohibit the type of cannabis business establishment proposed in the precinct of the proposed cannabis business establishment is filed prior to the filing of the application or within the 7-day period after the filing of the application, the municipality shall not approve the application for at least 90 days after the city clerk publicly posts the notice of intent to initiate the petition process. If a petition is filed within the 90-day petition-gathering period described in subsection (c), the municipality shall not approve the application for an additional 90 days after the city clerk's receipt of the petition; provided that if the city clerk rejects a petition as legally insufficient, the municipality may approve the application prior to the end of the 90 days. If a petition is not submitted within the 90-day petition-gathering period described in subsection (c), the municipality may approve the application unless the approval is otherwise stayed pursuant to this subsection by a separate notice of intent to initiate the petition process filed timely within the 7-day period.
If no legally sufficient petition is timely filed, a minimum of 12 months must elapse before a new notice of intent for that same precinct may be submitted.
