The wisdom of amending the zoning map or the text of this title is a matter committed to the legislative discretion of the corporate authorities and is not dictated by any set standards. However, in determining whether a proposed amendment should be granted or denied, the corporate authorities should be guided by the principle that its power to amend this title is not an arbitrary one but one that may be exercised only when the public good demands or requires the amendment to be made. In considering whether that principle is satisfied in any particular case, the corporate authorities should weigh the following factors:
A. Existing uses and zoning classifications of properties in the vicinity of the subject property;
B. Trend of development in the vicinity of the subject property;
C. Extent to which the value of the subject property is diminished by the existing comprehensive plan designation or zoning classification;
D. Extent to which such diminution in value is offset by an increase in the public health, safety, and welfare;
E. Extent, if any, to which the use and enjoyment of adjacent properties would be affected by the proposed amendment;
F. Extent, if any, to which the value of adjacent properties would be affected by the proposed amendment;
G. Extent, if any, to which future orderly development and redevelopment of adjacent properties would be affected by the proposed amendment;
H. Suitability of the subject property for uses permitted or permissible under its present comprehensive plan designation or zoning classification;
I. Availability of adequate ingress and egress from the subject property and the extent to which traffic conditions in the immediate vicinity of the subject property would be affected by the proposed amendment;
J. Availability of adequate public utilities and essential public services to the subject property to accommodate the uses permitted or permissible under the present comprehensive plan designation or zoning classification;
K. Length of time that the subject property has been vacant or underutilized, in consideration of the context of the pace of development and redevelopment in the vicinity of the subject property; and
L. Community's need for the proposed map amendment and for the uses and development that it would allow. (2005 Zoning Code)
