An official comprehensive plan, or any amendment thereof, or addition thereto, proposed by a plan commission shall be effective in the municipality and contiguous area herein prescribed only after its formal adoption by the corporate authorities. Such plan shall be advisory and in and of itself shall not be construed to regulate or control the use of private property in any way, except as to such part thereof as has been implemented by ordinances duly enacted by the corporate authorities. At any time or times, before or after the adoption of the official comprehensive plan by the corporate authorities, such corporate authorities may designate by ordinance an official map, which map may consist of the whole area included within the official comprehensive plan or one or more separate geographical or functional parts, and may include all or any part of the contiguous unincorporated area within one and one-half miles from the corporate limits of the municipality. Such map or maps shall be made a part of the ordinance, which ordinance shall specifically state standard requirements of the municipality relating to size of streets, alleys, public ways, parks, playgrounds, school sites, other public grounds and ways for public service facilities; the kind and quantity of materials which shall be used in the construction of streets and alleys; and the kind and quality of materials for public service facilities as may be consistent with Illinois Commerce Commission or industry standards, and shall contain the standards required for drainage and sanitary sewers and collection and treatment of sewage. The map shall be drawn to scale, shall be reasonably accurate, and shall show north point, section lines and numbers, and streams.

    The official comprehensive plan and the ordinance or ordinances including the official map shall be placed on file with the municipal clerk and shall be available at all times during business hours for public inspection. Copies of the plan, all ordinances implementing the same and including the official map, shall be made available to all interested parties upon payment of such sum as the corporate authorities shall determine to be adequate to reimburse the general fund of the municipality for the cost of printing and distributing the same.
