 (from Ch. 24, par. 11-12-7)Sec. 11-12-7.         The corporate authorities may initiate plans and maps by requesting the  plan commission to prepare an official comprehensive plan and recommend the  same, or may originate an official comprehensive plan, or a part thereof,  or an amendment thereto, and may refer same or suggested changes in an  existing comprehensive plan to the plan commission for its consideration  and recommendation thereon. No comprehensive plan or amendment thereto  shall be adopted that has not been submitted to the plan commission.The corporate authorities may adopt parts of a comprehensive plan  recommended by a plan commission without adopting the entire comprehensive  plan as recommended, or may modify or amend portions of a recommended  comprehensive plan without a re-reference of same to the plan commission,  and may adopt such comprehensive plan, as modified or amended. Such  comprehensive plan, when adopted, shall be the official comprehensive plan,  or part thereof, of that municipality.Upon submission by the corporate authorities of any suggested  comprehensive plan, part thereof, or amendment to an existing comprehensive  plan to the plan commission for consideration and recommendation, the  corporate authorities may require a report thereon from the plan commission  with its recommendation within 90 days from the date of such submission,  and if the plan commission shall fail to make such report within such 90  days, then the corporate authorities may proceed to consider such  comprehensive plan, or part thereof or amendment to an existing  comprehensive plan, for adoption, including arranging for and holding of a  public hearing thereon in accordance with the provisions hereinafter  contained in the same manner as if the plan commission had made its  recommendation.On and after the effective date of this amendatory act of 1961, an  official comprehensive plan, or any amendment thereof, shall not be adopted  by a municipality until notice and opportunity for public hearing have  first been afforded in the manner herein provided. Upon submission of a  comprehensive plan by the plan commission, or a proposed amendment to an  existing comprehensive plan, the corporate authorities shall schedule a  public hearing thereon, either before the plan commission or the corporate  authorities. Not less than 15 days' notice of the proposed hearing, and the  time and place thereof, shall be given by publication in a newspaper of  general circulation in the county or counties in which the municipality and  contiguous unincorporated territory are located. The hearing shall be  informal, but all persons desiring to be heard in support or opposition to  the comprehensive plan or amendment shall be afforded such opportunity, and  may submit their statements, orally, in writing, or both. The hearing may  be recessed to another date if not concluded, if notice of the time and  place thereof is publicly announced at the hearing or is given by newspaper  publication not less than 5 days prior to the recessed hearing.Within 90 days after the conclusion of the hearing, the corporate  authorities, after consideration of the recommendation of the plan  commission and such information as shall have been derived from the  hearing, shall either adopt the comprehensive plan or amendment in whole or  in part or reject the entire comprehensive plan or amendment. If adopted,  the corporate authorities shall enact the ordinance including a map or maps  as hereinbefore provided. In adopting an official comprehensive plan,  except as herein otherwise provided, the corporate authorities shall be  subject to the same limitations as to subject matter as apply to the plan  commission. If at the expiration of such 90 days, the corporate authorities  have taken no formal action, the comprehensive plan or amendment thereto  may thereafter not be acted upon by the corporate authorities without again  complying with the conditions of notice and hearing heretofore provided.No official map, or amendment or addition thereto, shall be ground for  rejection of any plat of subdivision or resubdivision by the corporate  authorities, if application for final approval of such subdivision or  resubdivision is filed with the corporate authorities 15 days or more prior  to the date on which the ordinance approving the official map, or amendment  or addition thereto, is adopted.The comprehensive plan or amendment shall become effective upon the  expiration of 10 days after the date of filing notice of the adoption of  such comprehensive plan or amendment with the recorder of the county.  Whenever used in this Section 11-12-7 the words "plans" or "comprehensive  plan" shall be deemed to mean and include, where applicable, an official  map or maps.    (Source: P.A. 83-358.)
