(65 ILCS 5/9-3-1) (from Ch. 24, par. 9-3-1)
    Sec. 9-3-1. Any municipality may make a local improvement whenever the public necessity requires such improvement, subject only to the limitations prescribed in this Division 3. This Division 3 shall not be construed as repealing any other laws with respect to local improvements, but shall be considered as an additional grant of power for the purposes herein set out. Any number of streets, avenues, lanes or alleys, or any other public places, or parts thereof, to be improved may be included in one proceeding (even though they may be intersected by previously improved streets, avenues, roads or alleys which are not included in the proceeding) where they are contiguous or part of a connected system with reciprocal benefits.
